Google wireless-g repeater. Comet Tuttle (talk) 05:38, 19 January 2010 (UTC)[reply]

It's not entirely a matter of range - three floors isn't much distance for a regular WiFi system. The bigger problem is the amount of intervening walls, floors and ceilings which attenuate the signal. Remember also that the signals have to go both ways - so while getting a higher power router helps in getting signals out to your PC's - it won't help with getting them back again because that's down to the transmitter power in the PC's - which you can't reasonably change. The idea of using wireless repeaters (as Comet Tuttle suggests) is therefore the better answer. SteveBaker (talk) 03:53, 20 January 2010 (UTC)[reply]

I write graphics programs in BASIC using SCREEN 12 mode which gives a display size 640x480 pix and 16 colours. I would like to change the palette colours, for example to a 16-step grey scale, by POKE'ing bytes into the palette address. (There is a PALETTE command but I have not succeeded in using it to get what I want.) Can anyone tell me the address where the palette is stored? Cuddlyable3 (talk) 12:07, 19 January 2010 (UTC)[reply]

It is not stored in memory but in VGA registers, so you would need OUT instructions, or whatever they are called in Basic. (If not OUT try PORT or something.) —Preceding unsigned comment added by 195.35.160.133 (talk) 13:13, 19 January 2010 (UTC)[reply]

The part of the VGA you need to OUT to is called the DAC (Digital Analog Converter). It has 256 byte-triplets for the red-green-blue values of the max. 256 vga colors. Technical details here: [[1]]. Btw, PALETTE should work too, I think. 195.35.160.133 (talk) 13:25, 19 January 2010 (UTC) Martin.[reply]

In QBasic 1.1, when you are using SCREEN 12, you can use the PALETTE statement as follows:

PALETTE n, r + (256 * g) + (65536 * b)

where n is 0 to 15, and r, g, and b are 0 to 63. --Bavi H (talk) 01:11, 20 January 2010 (UTC)[reply]

PALETTE command in Turbo Basic is different. The second parameter is not an rgb triple, it is an index 0 to 64 into the VGA palette. (That's according to the manual. I wonder why 64 and not 63. On trying it I get various colours but no grey scale.) Cuddlyable3 (talk) 22:54, 22 January 2010 (UTC)[reply]

I couldn't find a manual, but did find a copy of Turbo Basic and played around with it. In QBasic, the PALETTE command accepts a different range of arguments depending on what SCREEN mode you are in. However, it seems the Turbo Basic PALETTE command only lets you choose from the 64 colors available in the VGA text mode (SCREEN 0 with a VGA monitor), no matter what SCREEN mode you are in.

value = (r and 1)*32 + (r>1)*-4 + (g and 1)*16 + (g>1)*-2 + (b and 1)*8 + (b>1)*-1

PALETTE n, value

Note: (x and 1) is 0 if x is even, otherwise 1. (x>1) is -1 if x>1, otherwise 0.

r, g, and b can be 0 to 3. value ends up being 0 to 63. (Not 0 to 64, probably a misprint in the manual.)

The only grayscale values are 0 (black), 56 (dark gray), 7 (light gray), and 63 (white). --Bavi H (talk) 07:41, 23 January 2010 (UTC)[reply]

The EGA color palette has more info about this set of 64 colors. --Bavi H (talk) 02:15, 24 January 2010 (UTC)[reply]

After a little searching, I found The VGA palette, QBasic, and you, which shows the appropriate OUT commands to use as a faster alternative to the PALETTE statement. --Bavi H (talk) 02:51, 20 January 2010 (UTC)[reply]

I found how to get the 16-step grey scale. The 16 colours numbered 0..15 mode have to be non-linearly mapped to palette indices thus:

for c=0 to 15   'c is colour
 select case c
   case 0 to 5, 7
     cc=c
   case 6
     cc=20
   case else 'i.e. c=8..15
     cc=c+48
 end select
 out &H3c8,cc 'put the palette index in the DAC Write Address register
 
 'write 3 bytes RGB of a grey tone
 for n=0 to 2
  out &H3C9,c*4  'DAC Data Register. Allowed values are 0..63
 next n
next c

is JSP a Servlet?

Assuming you mean JavaServer Pages then "Architecturally, JSP may be viewed as a high-level abstraction of Java servlets." (from the article).87.102.67.84 (talk) 13:35, 19 January 2010 (UTC)[reply]

JSP is a technology, encompassing a programming meta-language, a compiler integration technology, and a set of standard practices for installing on a web server. A servlet is a specific compiled incarnation of a specific program that conforms to certain specifications. JSP can be used to generate servlets - these technologies are commonly used together and integrate well. Servlets can also be compiled directly from Java source code, without ever writing JSP. JSP can also operate a dynamic web page without ever compiling a servlet, but this is uncommon. Nimur (talk) 20:18, 19 January 2010 (UTC)[reply]

It usually refers to a search engine of software cracking tools—used for pirating software, games, etc. The cracks are programs that modify the original program in order to eliminate its copy-protection schemes. I suspect they have gotten a lot less necessary for pirating these days, as it has become more common to just download the entire, cracked program available via torrent websites.

What geographical information is in the following telephone number?

007077226…and then three digits which I omit for privacy

As far as I understand, 007 is Russia and Kazakhstan, and the following zero is perhaps somehow not part of the area code, but inserted for all international calls (if so, wouldn't that make the country code +70 instead of +7?), but I failed to find any area codes starting with 77 (or 077) in lists of area codes: kasach.de, Rostelecom, Kazakhstan (Казахстан), Russia (Россия)

So, is it a special number (mobile phone? secret service? god?), or did I get something wrong and it's a normal place like eastern Kazakhstan or Almaty? 23:37, 19 January 2010 (UTC)

I assume by the wording in your question that you are located outside of Russia and inside Europe, so your international dialing prefix is "00". Is that correct? Also, are you sure this is exactly how the number was written (i.e. are you sure the "007" is a country code and prefix as opposed to part of a local number)?

The reason I ask is because the number you give is also one digit short. Normal Russian phone numbers are 10 digits, in the format (NNN) XXX-XX-XX after you remove the country code and prefix. In addition, no Russian phone number has an area code starting with 7, and Kazakstan's area codes all seem to be 71x or 72x. Xenon54 / talk / 01:15, 20 January 2010 (UTC)[reply]

Thank you. Yes, I am in Germany, and I've given the number as displayed in the phone (somebody called in the early morning), minus the last 3 digits. I'm not sure but I don't think there's anything that starts with 00 except calls from/to abroad. The phone always shows calls from abroad as 00, followed by the country code. The easiest thing would probably be to call back and ask, but that's expensive and requires a common language. Somebody must have dialed the wrong number, but it itches me that whoever it was seemingly called from nowhere. I've added another list of Kaz. area codes to my original post. 84.46.48.150 (talk) 01:32, 20 January 2010 (UTC)[reply]

Hmm...interesting. Germany's phone numbers are 10 digits, correct? Continuing the theory that the caller is from Kazakhstan: perhaps the mysterious caller's number was too long to display properly. Try going to yellowpages.kz (in English, surprisingly) and typing in the number beginning from 226, leaving the drop-down at any city. See what comes up. If you don't get any results (because the linked website is "yellow pages" and thus businesses only) that doesn't rule out the number being a residential area, but as there are no white pages for the country you would be out of luck. Xenon54 / talk / 02:07, 20 January 2010 (UTC)[reply]

How it used to be is like this: '00' is the international access code in use in most countries, '7' is the code for Russia. Unlike most countries, Russia did not drop the leading '0' from area code; so '077' would be the area code of a city somewhere in Russia. However, according to Telephone numbers in Russia, there have been many changes including the replacement of area codes with a leading '0', so the '077' could be an obsolete area code. The international operator here in the UK confirmed that the leading '0' is no longer needed.

The operator did propose another theory though, that the number is infact a UK mobile and someone has added the '007' international code to Russia thinking that it is needed if the person is visiting Russia (it isn't - just enter the number as if they were still at home). However, I did notice that if that was the case there are too few numbers for a UK mobile. Perhaps this is nothing to do with Russia at all and it's just a UK mobile number with an extra zero on the very front. Or perhaps it is nothing to do with UK mobiles but another country's mobile service (one that uses only 9 digits). What happens when you call? Astronaut (talk) 02:06, 20 January 2010 (UTC)[reply]

Actually, since they called you the caller's number should appear to come from a real place. I think the only way you are going to find out is to call them back. TBH is is likely to be a wrong number - if they really want to speak with you, they'll probably call again. Astronaut (talk) 02:08, 20 January 2010 (UTC)[reply]

And if it is a UK mobile number, use caution - 07077 mobile numbers are 'personal' or 'vanity' numbers and some are used under the PN2 system which have the ability to be diverted anywhere in the world, some of the cost of which is charged to the caller. Nanonic (talk) 02:14, 20 January 2010 (UTC)[reply]

Thank you people for your efforts, I didn't expect anyone to go to the trouble (and cost?) of calling and asking an operator! You're a very helpful bunch! To Xenon: When this phone truncates numbers for display, it attaches a "…" in front of what fits in the display to indicate removal of the first digits. I tried your yellow pages, which showed no results for the exact number and likely variants, but showed a few numbers in Almaty and Astana starting with the first four digits (226X). What I know about German phone numbers is this: I dial 0+four digits for my grandmother's village and three digits for her house, newer lines have longer numbers. The city I live in has 0+two digits area code followed by a number of six to eight digits of which the first must not be 0. To Astronaut: The caller called on 2009-01-19, so they couldn't have used an obsolete code. The German counterpart to the UK's 070 numbers are 0700 numbers. I've checked several times, and the number at hand does not start with 070…, but with 0070… as given above. I haven't understood the operator's theory, but if it were a UK number, wouldn't my phone show 0044… as it does with simple landline callers? Not sure about this, though – I don't think I've ever had somebody call here from a special personal/vanity number. Oh, and a UK person probably wouldn't have called between 5 and 6 am. To Nanonic: Since it doesn't look like a UK number to me, I might try VoIP later to call our mysterious caller back. Will post result here.

Hello! I have a laptop that can connect to my TV so that I can see the screen and watch Internet TV. I use a wireless mouse to navigate from my couch. The problem I have is when I watch some full-screen videos, the player ignores all input and I must walk up to the laptop's keyboard and press ESC to access another video, change the channel, etc. I was wondering if anyone could write me a program so that when I right-click on my wireless mouse, the program "translates" the input and fires an ESC key event so that I can exit from full screen without getting up (and satisfying my laziness :) ). If it's C, I can compile the source on my side. If that's too much to ask, I would appreciate some pointer for writing the code myself (navegating the Windows API has been a disaster, and registering a global hook that can communicate with another application has been beyond my comprehension.

Yeah, and I vaguely recall that our conclusion was that no, an AWT Robot can't intercept mouse events unless it already has focus. You could try some clever tricks, like keeping the robot focused, but forwarding events to the intended program; but in general this isn't really going to work very well.

I've asked a similar question before about this issue, but have not been able to get a solution, unfortunately. My problem is I have a folder moved from Vista to Ubuntu over my network. It still has Vista permissions on it, so my Ubuntu machine can't modify the folder (I actually just want to delete it), but my Vista machine can't delete the folder on Ubuntu because it doesn't have the Ubuntu permissions. I'm wondering if I can get Samba to allow all activity from my Vista machine (modifying and deleting folders, etc.) and yet still deny access from anyone else?

Well, if the folder has been copied over, it will not have "Vista permissions". It may have limited permissions on Ubuntu, and it may belong to a different user from your normal account, but its permissions are under Ubuntu's control. Open a terminal, navigate to the folder containing your folder, and do either of sudo chown -R `whoami` stubornfolder; chmod -R u+rwx stubornfolder (to make it yours and grant yourself all rights), or simply do sudo rm -r stubornfolder. sudo may ask for your password, depending on the configuration. --Stephan Schulz (talk) 12:44, 20 January 2010 (UTC)[reply]

Ok so I recently (well, 6 months ago) upgraded just about every component of a PC I bought in '07 that came with Windows XP, and now it's demanding to be re-activated. It claims I can do it online, but won't let me connect to the internet (I guess because it won't let me do anything until it's re-activated.) So I tried doing it over the phone but it was one of those weird "I'm a robot, read off some numbers to me" things, so even though it didn't work I figure it could just be because "3" sounds like "Z" or something.

If it's an OEM version of Windows (and it sounds like it is because you said it came with the PC), then you shouldn't be able to reactivate it. I'm afraid OEM licences are for the machine they're sold with and can't be transferred (unlike retail licences which can). From Microsoft's point of view changing the motherboard is basically creating a whole new computer (which is essentially what you've done) and when changing a motherboard on an OEM licence it should be changed by the original OEM manufacturer who should supply a compatible one (if not exactly the same) thus not breaking the EULA so it can be reactivated.

I haven't played a game on my PC since the days of Quake, MDK and Riven. Can anyone recommend a good game to get me back into it? I like Myst/Riven type adventures, also shoot-'em-ups, but I'm not too keen on war scanarios - I prefer puzzle solving or the odd worlds of MDK etc. 86.150.103.201 (talk) 15:40, 20 January 2010 (UTC)[reply]

For a point and click game in the same vein as Myst I recommend Syberia.

For First Person Shooters, it's harder to say. That genre has grown enormously since the days of Quake. Do you want squad-based survival horror? Try Left 4 Dead. Action Packed soldiering? Try Modern Warfare II. Creepy retro-future single-player? Bioshock. First Person puzzle game? Try Portal. And that's just for starters. APL (talk) 15:56, 20 January 2010 (UTC)[reply]

Wow, no games since the days of Quake? You missed out on a number of classics :) Sadly, adventures in the style of Myst and Riven have pretty much disappeared, but the AGS community is still pretty active...you can find a number of free adventure games on Big Blue Cup, the main AGS website. As far as firt-person shooters go, Half Life and Half Life 2 were pretty good (if you decide on getting Half Life 2, get the Orange Box, that way you'll also get Portal as a bonus - it's pretty short, not really a full game, but had extremely innovative and funny puzzle gameplay). My favourite Shooter in the last couple of years was Deus Ex - it's more of a hybrid of FPS and RPG gameplay, and it has the best storyline I've ever found in a game. If you don't mind the violence and occasional profanity, have a look at the GTA series - I'm still hooked on GTA San Andreas's early 90s nostalgia and open-world sandbox gameplay. -- Ferkelparade π 16:09, 20 January 2010 (UTC)[reply]

Yeah, well, I thought I was too old to be playing them ... but an old nostalgia has crept over me. Never was a techie, so another related question from me - are games much better on a Gameboy/Nintendo/whatever the gizmo of choice is these days etc than a PC? Do they justify the cost? Or should I just stick with my PC? Thanks for all suggestions so far. I ought to add I'm female so the war scenario games don't do it for me though I did enjoy the sniper-scope in MDK with the mooning aliens. 86.150.103.201 (talk) 16:17, 20 January 2010 (UTC)[reply]

Well, the main difference between PCs and consoles is that consoles are (in theory) hassle-free - you just put in the game disc and start playing without ever worrying about graphics drivers or hardware upgrades. The downside is that all consoles have a somewhat limited choice of games compared to whats's available for Windows PCs (still enough to keep you occupied for months, probably :) and that the controllers used by consoles take some getting used to and don't work too well for certain types of games (I can't play first person shooters or strategy games without a mouse, but that may just be me). All the games recommended by APL and me are already a couple of years old, so they will run on relatively modest hardware and probably not require you to spend huge sums on upgrading your PC -- Ferkelparade π 16:34, 20 January 2010 (UTC)[reply]

While the PC has "more" games, I'm not sure that's a selling point. The vast array of crap tends to hide the good stuff, and the best games of recent memory sometimes don't release for the PC or delay the PC release for weeks or months. I'd argue that between the Xbox and the PC, the Xbox has more variety in modern games. That said, if she hasn't been playing since Quake and Riven, she's got a long backlog of good games for the PC. —ShadowRanger ^(talk|stalk) 16:49, 20 January 2010 (UTC)[reply]

It's not true that point and click adventure games have disappeared. They're a large market. Walk into a Best Buy and they'll have an entire shelf of them for PC! (It's just that shooter games have gotten larger.) Of course, only a certain percentage of those are worth playing, But that has always been true.

Try games by The Adventure Company. There are also a good number of adventure games for the DS. (Try Hotel Dusk) If those aren't "lighthearted" enough, The most recent Sam & Max game was in '07. That's not exactly point-and-click, but it's similar.

If you liked first person games like quake, and you like puzzles, I do recommend Portal (video game). It's quite good. APL (talk) 16:44, 20 January 2010 (UTC)[reply]

Half-Life 2 is one of the more rewarding recent games I've played—it sucks you in pretty good, and has an excellent balance of action and puzzle sequences, great plot pacing, clever innovations, etc. GTA: Vice City is a great way to try out a "sandbox" style game. I tend to go for games that came out a couple years ago—the prices are usually low, my not-totally-up-to-date system can usually handle them just fine, and it's easier to figure out which are the stinkers and which are really worth your time. Deus Ex is a bit older but I thought it was pretty enjoyable as well. --Mr.98 (talk) 16:39, 20 January 2010 (UTC)[reply]

(ec)Games are *different* on a console vs. a PC. For certain genres, they may be better or worse (FPS games are usually better on a PC due to the enhanced precision of a mouse, but you may lose out on online matchmaking and co-op play that is more common on the console). RTS games are frequently harder to play on a console as well (though the Wii seems like it would work well, since the Wiimote can substitute for a mouse). And RPG type games are usually simplified for a console; on the other hand, any RPG released on both PC and console will likely be similarly simplified on the PC. That said, while the number of available controls is less on a console, it's easier to use them all due to the ergonomics of the controller, and game conventions are little more static, so it's often easier to translate your muscle memory across games. Shooting uses the trigger buttons, A (on an Xbox) is usually a movement related button (jump or roll), etc. While I still feel RPGs lose out from the reduced control set, action/adventure games which use less controls, but use them all frequently (e.g. Shadow Complex, Assassin's Creed and its sequel, Batman: Arkham Asylum) often benefit from the fact that all the controls are equally accessible.

Consoles provide a more consistent experience at a lower price; a PC capable of playing the most modern games will run at least twice what the console would, and is often less stable due to the array of hardware involved, but the graphics and load times can be much better in exchange. You'll have more options on a console too, particularly on a 360, less so on a Wii; the PS3 has some good exclusives, but far less games in general, and the multiplatform games released for it are usually better on the Xbox or PC. Porting to the PC adds enough of a test load that smaller game companies often don't bother.

I don't know of many Myst/Riven type games nowadays; on the other hand, most of my friends that appreciated that genre like the story driven games like Way of the Samurai. You might also like puzzle games like Braid. For FPS games, Left 4 Dead and its sequel are a good game to start on now; it encourages team play, and it works well on both console and PC (since zombies don't dodge much, the loss of precision with a console analog stick isn't a huge deal). —ShadowRanger ^(talk|stalk) 16:45, 20 January 2010 (UTC)[reply]

Oooh I've just looked at the trailer for Half Life 2 - looks good, with those war of the world tripods. Syberia looks like my sort of thing too.

Just a note: I wouldn't discount GTA IV based on the reputation of the franchise. While you can play it as a sandbox mafia game, it actually features a reasonably in-depth storyline; the main character is at least somewhat conflicted by the actions he takes, it's not just "I'm the best, so I kill everyone and take their stuff". I haven't finished it myself (only just unlocked the third island), but it's not a mindless violence type of game. Yes, when you do fight, it's people, so weigh that yourself, but there's more to it than killing people (there's a reason the game is the highest rated Xbox game of all time on Metacritic). Also, for a shooting game that isn't just shooting (and features more alien surrounding), I'll plug Mass Effect. It's a hybrid RPG/shooter (weighted in favor of RPG) that features a decent storyline and some pretty awesome settings and enemies. —ShadowRanger ^(talk|stalk) 16:56, 20 January 2010 (UTC)[reply]

I lost interest in GTA games now that I can get my "driving around recklessly" fix from "Offroad Raptor Safari". (Buy here, Play Free on Facebook Here) APL (talk) 17:53, 20 January 2010 (UTC)[reply]

Mass Effect (which I mentioned before) has a range of body types. The female version of the main character (you choose the gender) has what I'd guess are around a B cup (my ability to gauge exact cup size isn't great, but it's no larger than a C cup, and I'm pretty sure A cup is flatter), though it's hard to tell through armor. An example can be seen here (ignore the specific facial features, which are customizable). I think the human female NPC that serves as a potential romance target is a little larger, but I'm pretty sure she's still well below D cups. I should warn you though, Mass Effect does occasionally involve killing humans. I can only think of one main story quest where it's required (tracking down a lead, you have to fight through a bunch of thugs protecting a minor crime lord, and some of those thugs are human). That said, most of the combat will be against sentient machines, creepy plant creatures, and psionic insectoids. The fights against humanoid creatures are less common, and those are fairly evenly split between the various combat capable sentient races of the galaxy, meaning humans are less than 10% of your total foes. Aside from the quest I mentioned, I believe it is possible to avoid killing any humans in the rest of the game, through diplomacy and avoiding certain side-quests. —ShadowRanger ^(talk|stalk) 17:57, 20 January 2010 (UTC)[reply]

One problem with PC games is the never ending cycle of developers stretching the latest/fastest/best hardware to the absolute limit.

If you like a combination of adventuring and at-your-own-pace shooting, I can't recommend Fallout 3 highly enough. Also, if you're thinking of taking up shooters, you will find that Team Fortress 2 is an excellent light-hearted FPS (with fairly modest requirements).

If I create a cone in OpenGL, it will point in the ${\displaystyle (0,0,1)}$ direction. I want to rotate it, so that it ends up pointing in the ${\displaystyle \mathbf {v} =(x,y,z)}$ direction. Then I have to rotate (a positive angle) around the ${\displaystyle (0,0,1)\times (x,y,z)=(-y,x,0)}$ axis. To this end, I introduce a new orthonormal basis in ${\displaystyle \mathbb {R} ^{3}}$: I set ${\displaystyle \mathbf {f} _{1}=(x,y,0)/norm}$, ${\displaystyle \mathbf {f} _{2}=(0,0,1)}$, and ${\displaystyle \mathbf {f} _{3}=(-y,x,0)/norm}$, where ${\displaystyle norm={\sqrt {x^{2}+y^{2}}}}$. Hence, the orthogonal basis transformation matrix is

${\displaystyle T={1 \over norm}{\begin{pmatrix}x&0&-y\\y&0&x\\0&norm&0\end{pmatrix}}}$.

In this basis, we need to rotate the angle ${\displaystyle \varphi =\arccos {{(\mathbf {e_{3}} ,\mathbf {v} )} \over {\|\mathbf {e_{3}} \|\|\mathbf {v} \|}}}$ around ${\displaystyle \mathbf {f} _{3}}$. Hence the linear tranformation matrix is

${\displaystyle A_{f}={\begin{pmatrix}1&0&0\\0&\cos(\varphi )&-\sin(\varphi )\\0&\sin(\varphi )&\cos(\varphi )\end{pmatrix}}}$

so that the matrix in the standard basis is

${\displaystyle A_{e}=TA_{f}T^{t}}$.

Before I tell OpenGL to render the cone, I multiply the model-view matrix by ${\displaystyle A_{e}^{'}}$, where ${\displaystyle A_{e}^{'}}$ is obtained from ${\displaystyle A_{e}}$ by first adding a zero row and then adding the column ${\displaystyle (0,0,0,1)}$. But it appears not to work quite as one would expect. Why? —Preceding unsigned comment added by Andreas Rejbrand (talk • contribs) 18:56, 20 January 2010 (UTC)[reply]

I have a Mac using OS X 10.4. I'd like to use the characters "barred small capital i" (U+ID7B, ᵻ) and "barred Latin upsilon" (U+1D7E, ᵾ), which I've heard are available on newer versions of Lucida Grande, but on my version they just show up as boxes. See this not so enlightening exchange that I had with John Wells:

Lazar said... I'm still waiting for barred small capital i and barred Latin upsilon.

John Wells said... Lazar, didn't you like the ᵻ (U+ID7B) I gave you yesterday? Or have you not got the current Lucida Grande font installed? The other one you ask for is ᵾ (U+1D7E).

Lazar said... Oh, I have an older version of Lucida Grande. I must look into that.

I know this will seem like a dodge, but you're probably better off asking on the language desk.

Interesting question - I never thought that extended characters could be font related. I can't talk for Macs since I use Windows 7, but doing some tests on Microsoft Word it seems that weird characters are supported by all fonts. I'm not sure if it is font support or at some point there is a cut-off and it extends less common fonts into a system font that supports characters beyond ASCII. You should investigate unicode support for your Mac - see if there is a setup somewhere that allows you to change the default code page being used. AFAIK UTF8 (unicode) and variants like UTF8-AL32 support all languages and major characters (unless you happen to speak Klingon). Sandman30s (talk) 14:32, 21 January 2010 (UTC)[reply]

Note on your last point, many unicode fonts do however lack support for less common real world languages. Take a look at Help:Multilingual support (Indic) for example. Windows 7 & Vista are a lot better then Windows XP, but still lack the Burmese character set. Also for extinct languages, e.g. Gothic alphabet or Help:Fonts (we helped someone with this here once). [6] may also be of interest. Of course in some cases even if the fonts are there, the OS or browser may not handle Complex text layout properly, necessary for some languages. Nil Einne (talk) 14:34, 22 January 2010 (UTC)[reply]

If you don't mind any font, there may be a free font available which supports them. Usually I believe, the OS or browser will automatically use an alternative font if necessary so it should show up fine if you have at least one font. If you want Lucida Grande, I'm not sure if there's much we can do. Presuming your computer is up to date, it may not be possible. It's fairly common that fonts are not updated and you need a newer version of the OS or program to get the latest version. And scalable fonts are held to be copyrightable in the US [7] so you're not going to get help violating copyright here. And Lucida Grande is almost definitely copyrighted. P.S. If you know John C. Wells, could you see if we could get some other free photos of him?

An antivirus program recently detected a trojan - "Alureon" - the warning appeared when looking at e-mail (web based) in a browser - the trojan appeared to located in the browsers temp. directory.

Question: I can understand a web page downloading many unwanted things (but actually activating them is another thing), but what about a web based e-mail program (using ajax)- given that I didn't get any instructions to start an .exe or activeX, or similar - does this mean the trojan wasn't activated. If it could have been activated without me actually opening anything other than the email - how? Thanks.87.102.67.84 (talk) 16:07, 21 January 2010 (UTC)[reply]

You're probably okay; downloading a Trojan without activating it is usually harmless. The webmail site or your browser may have cached the attachment locally in preparation for downloading, but that doesn't mean they ran it. If there is a flaw in the browser (e.g. the recent zero day exploits against IE6, and to a lesser extent IE7/8), it might be exploited to activate the Trojan (in which case it's not properly a Trojan; a Trojan by definition requires the user to activate it). You should make sure your browser is up to date with the latest patches, if it isn't, or if you're running IE of some flavor (for which the known exploits have not had a patch released yet), you should run a full system scan with your regular virus checker and, if possible, one other checker (you don't need a second live scanner, but a second opinion system scan would be a good idea). —ShadowRanger ^(talk|stalk) 22:26, 21 January 2010 (UTC)[reply]

One unusual thing that happened was a memory access error from adobe reader when I shut the system down (never happened before) - this makes me suspicious of noise on the system - maybe something like a buffer overflow exploit messing up memory. Enough to make me reinstall.

However if my suspicions are true - it's not clear to me how using just html and javascript such a thing could (overflow) have been done. I thought I understood that modern OS's just didn't allow memory writes outside a sandboxed area set aside. It's possible that the adobe error had nothing to do with it. Any clues?87.102.67.84 (talk) 00:06, 22 January 2010 (UTC)[reply]

Assuming there was a JS exploit, they don't need to infect the OS itself immediately. If they can break the JS interpreter, they can just request the OS write a file and start a program; any program can do this unless that privilege is explicitly removed. The browser is designed to not start programs without user interaction, but if the browser itself was compromised, it can do anything you can do (although it can't take admin privileges on Linux or Vista or later machine unless the OS itself has an unpatched vulnerability). Even without admin privileges though, it can write to your user directory, create registry entries specific to your login, etc. Admin privileges are needed to hide itself from virus scanners well, but they aren't required to listen to keystrokes, operate a covert server on your machine, and run most programs. —ShadowRanger ^(talk|stalk) 15:58, 22 January 2010 (UTC)[reply]

Why when running DOS, Win 95 98 or ME in a virtual machine does it always use 50% of hosts cpu when idle, whereas running Win 2000, XP, Vista or 7 in a virtual machine uses very little of the host cpu when idle? —Preceding unsigned comment added by 82.43.91.83 (talk) 16:45, 21 January 2010 (UTC)[reply]

I'm not familiar with this behavior (I've only used VMs in the past five years or so, and usually with XP or more recent OSes), but I can provide a theory. The high CPU OSes you mention are all OSes that provide some level of direct access to the hardware by random programs. Simple actions like polling for I/O must be intercepted, interpreted and then passed along to the safe interface used by the host OS. In a more modern OS that shares the aversion to direct hardware access, you can recognize and rewrite the API calls on load to point to the VM manager's functions that pass them to the host OS. On an older OS, the lack of an API means you need to examine every memory access to see if it's trying to access "special" addresses associated with hardware under the old OS. There's no marking to tell you ahead of time that the address is special, so you're stuck with dynamic interpretation on the fly.

Again, this is a theory. I'm a CS major, and I worked with people on the VM team at Microsoft, but I'm not an expert; take this as the likely explanation, but don't rely on it to land on the moon, pass a test, etc. :-) —ShadowRanger ^(talk|stalk) 22:17, 21 January 2010 (UTC)[reply]

One additional note: The 50% really means 100% of one core, it's not some magic number. The VM is completely occupying a single CPU, and you have a dual core (or hyperthreaded) machine. The VM tells the guest OS that there is only one processor, so as to maintain performance for the host OS and other programs competing for CPU. —ShadowRanger ^(talk|stalk) 22:20, 21 January 2010 (UTC)[reply]

What's the known lifespan of an e-Ink display? Does it only work for so many on-off cycles or so many years? What happens when they stop working? Does it go light/dark/or freeze the last image? --70.167.58.6 (talk) 18:53, 21 January 2010 (UTC)[reply]

The manufacturer does not give it a lifespan. It is electronic, so it will eventually wear out. It is also pixel-based. There are a bunch of little capsules (like pixels) that can be one color or a different color (black/white is normal). The color changes based on the charge behind the capsule. It is possible for a capsule to break through force - such as slamming the display with a hammer. I see the circuit behind the crystal as the point of failure. I expect that when it begins to fail, you will see lines where it is always white or always black - very similar to what an LCD display looks like as it begins to fail. -- kainaw™ 22:03, 21 January 2010 (UTC)[reply]

I'd suspect, based on what I know of the technology, that the lifecycle would be measured primarily in on-off cycles. On the other hand, I suspect the screen itself won't be the main point of failure in these devices; damage due to accidents and poor care, combined with the relatively short useful life of the built-in batteries are likely to off it before the screen has been used enough to suffer wear from mere pixel cycling. —ShadowRanger ^(talk|stalk) 22:08, 21 January 2010 (UTC)[reply]

Now that I think about it... Being off for an extremely long time will likely cause the charged "ink" to lose some charge. Being on puts a charge near the ink, so it will tend to work properly. Being off places the positive/negative charged ink near each other. I see it similar to tossing bunch of magnets in a drawer. If left for an extremely long time, some won't work as well. However, we are talking about long after the circuit to charge/discharge the ink has worn out. -- kainaw™ 22:19, 21 January 2010 (UTC)[reply]

I think the charge is chemical (eg think of charged surfactant like molecules (eg oleyl trimethyl ammonium) embedded in a polymer with the counter ion (eg Cl-) being soluble - slightly different in practice) - so loss of charge as such wouldn't be a problem. Excluding the damage to wires already mentioned above, I'd expect degradation of the polymer to be one problem - eg especially under uv light or in radical rich enviroments (eg a sunny california, outdoors and in the smog) - a glass cover would stop most of this. Simple things like the charged particles starting to stick together (agglomeration) would reduce effectiveness over time, which is not beyond the bounds of possibility. Thickening of the carrier liquid (again uv light) could slow or eventually stop response. Beyond that there is much I can think of - they may be very long lasting - I couldn't find any much data either.87.102.67.84 (talk) 23:20, 21 January 2010 (UTC)[reply]

Hello! Consider the following code snippet:

//Thread 1 extends Thread
InputStream in;
byte[] bytes = new byte[100];
//... in is initialized properly, but may or may not contain bytes yet
try{
in.read(bytes);
}
catch(IOException e) {
//ignore
}
catch(InterruptedException e)
{
//do something
}


//Thread 2
Thread_1 toInterrupt = new Thread_1();
toInterrupt.start();
//...
toInterrupt.interrupt();

If Thread_1 is interrupted while it is blocking waiting to read at in.read(), will an InterruptedException be thrown, and execution will switch from in.read() to code in the catch{} block? This is probably an easy question, but I'm just not sure if the method to interrupt must throw a checked InterrruptedException (like Thread.sleep()) for the interrupt to work properly. Thank you!--el Aprel (^facta-_facienda) 23:10, 21 January 2010 (UTC)[reply]

Yes, if the timing is right and Thread 2 executes the interrupt() call during a period when Thread 1 is still blocking on the read, then control for Thread 1 will transfer to the catch block, because an InterruptedException was received. (Thread 2 will continue marching along, unless you intentionally wait for some response or notification from Thread 1). in.read() is a blocking method. If it is interrupted, the behavior of the InputStream will depend on the instantiated class type of InputStream. You may or may not lose bytes as a result of this - again, check carefully whether the exact InputStream you instantiated is declared thread safe. (In other words, whether an interrupted read() operation guarantees some kind of rollback mechanism). If you're using one of the Sun implementations, thread-safety and behavior for I/O is defined in the javadoc. Also, note that Thread.interrupt() documents behavior if the java.nio InterruptibleChannel API is in use. ("If this thread is blocked in an I/O operation upon an interruptible channel then the channel will be closed, the thread's interrupt status will be set, and the thread will receive a ClosedByInterruptException.") For other cases, you may have to check with the sourcecode of the InputStream or unit-test it. This article from a Java developer news site discusses some finer details.

Thank you for the quick response, Nimur! Exactly what I needed to know.--el Aprel (^facta-_facienda) 00:13, 22 January 2010 (UTC)[reply]

Nonsense. Read does not declare InterruptedException. It will throw an InterruptedIOException instead. You can treat it specially if you put the InterruptedIOException catch block before the IOException catch block. —Preceding unsigned comment added by 80.226.1.7 (talk) 01:45, 23 January 2010 (UTC)[reply]

Ah. I think this is true. The InputStream may be implemented by a class which does throw that exception, but the way this code is written, it must be treated as a generic InputStream (irrespective of its additional capabilities at runtime). As the IP pointed out, the specific type of IOException that could be thrown is an InterruptedIOException. My mistake - I spoke too soon! Nimur (talk) 03:06, 23 January 2010 (UTC)[reply]

Internet in North Korea may also be of interest Nil Einne (talk) 14:00, 22 January 2010 (UTC)[reply]

There are certainly internet websites hosted in North Korea, and there is internet infrastructure there. The extent to which it is freely available is debatable, but there is absolutely physical network connectivity. There are also internal data and voice networks which are not connected to the globally-administered network system with global IPs assigned by ICANN and its collaborators. At this point, it's worth making a critical definition: "the" internet is just the largest interconnected network. There are dozens of other large networks - some even using identical IP-based technology - which are not connected to "the" internet. Nimur (talk) 18:55, 22 January 2010 (UTC)[reply]

Nimur: could you give a couple examples of such a large network which is not connect to The Internet? Enquiring minds want to know! (I'm assuming you are not just talking about large company or university intranets, right?) DaHorsesMouth (talk) 01:31, 23 January 2010 (UTC)[reply]

Large intranets are not really independent, because they use globally valid IP addresses and rely on the outside internet infrastructure for connectivity. NIPRNet has some connection to the Internet - however, its network infrastructure is entirely redundant to the civilian internet (it does not rely on any routers that constitute The Internet to get data from point A to point B). SIPRNet comes to mind as one entirely redundant internet that specifically does not connect to the globally addressable internet. How big is it? Where is it? You'll never know... But seriously, this is used for many in-country and out-of-country data connections, including things as diverse and benign as emails, telephone calls, and web sites, as well as things that we can only speculate about. Small regional and local independent and unconnected SIPRNets almost certainly also exist, but the likelihood that we will ever hear about them in public is close to zero. JWICS claims to be "worldwide." Surely other large organizations with sensitive networks, both inside and outside the United States, have similar systems. To some extent, any large LAN with more than one internetworked subnet can be called an internet, provided that it has a globally managed IP scheme, at least one or two routers (especially if they are peering using a border gateway protocol), and a unified domain name service which can be entirely unrelated to "the internet" DNS scheme.

I have been trying to print some work out from my computer, but all the colours are coming out rather different to they are on screen, mostly rather paler than I had wanted, but also dramatically bright, particularly the browns which look orange instead. At the same time, the print quality is rather bad, but the printer is pouring so much ink onto the page that the paper has been bent out of shape. And the margin on one side has gone, the pictures go right to the edge, where there is a row of smudgy triangles, presumably something to do with the way the ink moves back and forth over the paper. Is there any way of fixing all of this rather soon, such that I can get everything printed out nicely?

I am not a fan of Microsoft, but. Microsoft Office 2000 is 128mb in size, OpenOffice is 401mb. Internet Explorer is 4.7mb, Mozilla Firefox is 26.4mb. Why the huge difference in sizes? I've heard it said that Internet Explorer is smaller because it is integrated into Windows, but I should'nt think it makes that much of a difference. 92.29.31.202 (talk) 13:56, 22 January 2010 (UTC)[reply]

Um why are you comparing a 10 year old version of Office to (I presume) a modern version of OpenOffice? Also it's not clear to me where these sizes are coming from. I have the IE8 download for Windows XP x32 on my computer. It's 16.5mb. I also have the download for Firefox 3.5.3, it's 7.5 mb. Of course such sizes are not particularly useful since it depends on things like optional components, compression used etc. Are you referring to RAM usage when running? If so it'll vary depending on a number of factors. For example, what component of Office? For the browser, did you just open it with a single window, no tabs and no page open? P.S. The integration can make a big difference because the various components can make up for a substanial proportion of the size or memory usage. For example, if I could program, I could surely design a special version of Firefox with a download size of say 250k and memory usage of a few mb even with many windows open but it requires the 'Firefox support component' which is always running and is an additional download of say 10 mb with memory usage in the hundreds of mb with lots of windows open. Would you say this special Firefox is 'less bloated' then the normal Firefox? P.S. I hope you're not considering a version if IE older then IE8 considering what buggy POS they tend to be, particularly IE6 or older. Before someone says IE8 is the same, that may be partially true, but ignores the may point which is that however bad IE8 may be, IE7 and particularly IE6 and older are far worse Nil Einne (talk) 14:06, 22 January 2010 (UTC)[reply]

The size is the size of the program. MS Office 2000 is the only one I've got. Internet Explorer is version 8. Now I think of it Firefox may include the size of some plugins, but I recall the plugins were small in size. Let us not let hysteria triumph over an objective consideration of the facts. 92.29.31.202 (talk) 15:30, 22 January 2010 (UTC)[reply]

Keep in mind, OpenOffice and Firefox ship not just their executables, but all their support code in one package. By contrast, many elements of IE are common controls in the operating system; you paid the cost for them when you installed the OS in the first place. IE8 is less tightly integrated, but in older versions of IE, IE was just the menu bar and frame encapsulating an instance of the HTML rendering DLL that shipped with the OS, so you couldn't get an exact "size" of IE. Beyond that, we've reached the point where even small flash based hard drives are 32 GB in size or larger. A difference of a couple hundred meg is very little; most people only use a dozen programs or so, so even if you "wasted" 200 MB a pop (and keep in mind, the software may be providing additional features with the space used), you'd still only use up an extra 2.4 GB. My home machine has 1.7 TB of storage space, and maybe 10% of that is programs (and most of that is games, not productivity programs). If Firefox used five times the space I'd still consider the features to be worth it. —ShadowRanger ^(talk|stalk) 15:44, 22 January 2010 (UTC)[reply]

My Firefox version 3.5.6 is 17M. I don't have a single size for OpenOffice because you can download each part you want separately. The core that is always needed is 220M. After that, the word processor is 73K, the spreadsheet is 61K, and the presentation program is 58K. If I download everything, I'll never get to 401M. -- kainaw™ 14:48, 22 January 2010 (UTC)[reply]

Do you mean the word processor is 73M, the spreadsheet is 61M and the presentation program is 58M? Nil Einne (talk) 14:54, 22 January 2010 (UTC)[reply]

According to the download packages, each one is K. I double-checked because I couldn't see it being so small, but it says K. I figure you are downloading them in the core and then doing nothing more than downloading a launcher for each one with the separate packages. Rather stupid way to do it in my opinion. -- kainaw™ 15:13, 22 January 2010 (UTC)[reply]

In defense of the OpenOffice design philosophy, here's the Technology Overview - Component Interoperability whitepaper. Kainaw correctly points out that the ~50 kilobyte packages are separate launchers - formally, these are the "Application Layer." On account of the nature of modern digital documents, there is a System Abstraction Layer below this - effectively there's no difference between the software which runs the spreadsheet or the word processor, except for the user interface toolbars. This is necessary - what would you do if you had to open a document which contained a chart or table? You need the software subroutines which handle those components. Similarly, if you had a chart or spreadsheet with lots of text in one cell - that would be handled by the Text Processing routine. So, you need the entire core (technically, though, there are two sub-sets of the System Abstraction Layer, you can install separately). Nimur (talk) 23:42, 22 January 2010 (UTC)[reply]

On my Mac, MS Office 2004 is 524 MB, OpenOffice is 345MB. I would count these as being pretty much in the same range. Firefox is 50MB, Safari is 102MB. --Mr.98 (talk) 15:43, 22 January 2010 (UTC)[reply]

That's actually a good illustration of my point: On a Mac, the OS doesn't ship with the support DLLs Microsoft can rely on in Windows (for example, the Edit and RichEdit controls), so the program has to include them in the installer, so you see the cost of MS Office more accurately. That said, my point about hard disk space being infinite stands; the only way you run out of space on a home machine nowadays is media files (video in particular); programs really don't enter in to the equation. —ShadowRanger ^(talk|stalk) 15:48, 22 January 2010 (UTC)[reply]

Is it possible to create a .htaccess file that redirects while keeping the original URL displayed in the browser's address bar, even across filenames? 202.10.91.153 (talk) 16:50, 22 January 2010 (UTC)[reply]

I'm afraid not, any redirect will literally redirect them and the browser will show the new URL. The only way to do what you want is to have an HTML page on the server using a frame or iframe to point to the "real" site. ZX81 ^talk 17:09, 22 January 2010 (UTC)[reply]

(edit conflict) Yes, at least as long as the URL you're redirecting to is on your site. What you want is what Apache calls an "internal redirect" (as opposed to an actual HTTP redirect). With mod_rewrite, you accomplish that by not using the "R" flag in your RewriteRule (and making sure that the redirect target is not a full URL, or at least not one pointing to another site).

If you have both mod_redirect and mod_proxy installed, you can also use the "P" flag to issue an "internal redirect" to an URL on another site, at least sort of: what Apache does in this case is act as a proxy server, fetching the content of the URL from the other server and sending it back to the user as if it had come from your site instead. Ask yourself twice if this is really what you want to do, though: usually, it's not. —Ilmari Karonen (talk) 17:13, 22 January 2010 (UTC)[reply]

Good information, but those really strain the definition of "redirect". --Sean 19:07, 22 January 2010 (UTC)[reply]

Well, I think it works pretty good if you don't know it is called "mod_rewrite," which isn't exactly intuitive regarding what is going on.

Many years ago I was told that a CD would outlive a CD player if played constantly 24/7. Is this true? —Preceding unsigned comment added by 82.43.91.83 (talk) 17:59, 22 January 2010 (UTC)[reply]

I agree with the statement, but can't find a reference for the expected life of a CD in our compact disc article. (Anyone feel like remedying this?) Even a recordable CD, though, which is expected to experience disc rot way before a regular (non-recordable) CD, is expected to last from 20 to 100 years, according to the compact disc article. By contrast, I don't think a CD player could be expected to run for 20 years continuously without breaking. Again, though, I have no actual reference to cite. This situation is the reverse of a record player, where the vinyl record becomes scratched as the needle scrapes across the pits; a CD player only physically touches the CD on the inside rim, where there's no data stored. The data is read "touchessly" via a laser that just reflects off the CD's surface, so there's little opportunity for the CD to get scratched or degraded like a vinyl record in a record player is. Comet Tuttle (talk) 18:05, 22 January 2010 (UTC)[reply]

Makes sense to me. CD players have moving parts—moving parts break down pretty quick. The CD in the CD player is not doing anything but rotating—reading data off of it causes no wear. CDs do certainly "die" after awhile but it's not from being used in the player. They can, of course, get damaged when being put into a player, or being outside of the player. But once they are in, nothing really happens to them. --Mr.98 (talk) 23:52, 22 January 2010 (UTC)[reply]

I’ve rented a hosted dedicated server running Windows Server 2003 Web Edition for several years now. The server is mainly used as a web server (with Tomcat), but it’s also running e-mail (James) and SQL (MySQL) services. Starting sixteen days ago, the daily bandwidth usage skyrocketed according to the web hosting company, but the Tomcat log files don’t show a significant increase in HTTP bandwidth served. Furthermore, at the moment the network utilization shown on the Task Manager is low, so the super high bandwidth isn’t occurring all day. I suspect that maybe someone’s trying to hack the server using an attack that uses high bandwidth, but the attack isn’t going on all day. It would be very helpful to at least figure out which service is using up the bandwidth, so it would be very handy to be able to see the bandwidth over the course of a day broken down by how much of that bandwidth is going through each port. It would also be handy to see which remote IP address is using up the most bandwidth over the course of a day. Is there a more-or-less standard tool that would let me figure those two things out? I can’t find a tool built into Windows Server 2003 Web Edition that does what I need.

I happened to see a somewhat related thread above that mentions WireShark, so I’ve been reading some about that, thinking perhaps that would do what I need. But I’m concerned that for security reasons, my web hosting company might not be happy about me using a tool that puts the network card into promiscuous mode. Plus, I don’t have any need to see all the traffic passing through the network; I only need statistical information about packets that are addressed to my server. Since it sounds like there are ways of detecting a network card that’s in promiscuous mode, I’d prefer to not use a tool that uses promiscuous mode, to avoid any possibility of getting in trouble with the web hosting company. Red Act (talk) 01:50, 23 January 2010 (UTC)[reply]

Wireshark only puts the adapter into promiscuous mode if you tell it to; if you tell it not to, it just captures all the packets to and from this specific MAC (and broadcast and multicast packets).

I would like to use the public domain panel of drawings from this newspaper article in an article I am writing. I use Paint.NET for cropping/cleanup. I want to get the cleanest copy of the image I can, which I could if I could download the image and then manipulate it with the program, but the newspaper image (see previous link) provides pdf and "JP2" (which I think is JPEG 2000). I don't have Adobe Professional, which I think would allow me to save it as a different file format and then I could import that into Paint.NET. When I tried the download option, nothing on my computer supported opening the JP2 format, and I'm not how I could import that either even if I could download. Using print screen I need to make the image far too low a resolution to capture the six panel image with the descriptive text legible. I thought maybe I'd break it into two three panel images but the resolution still sucks. The only way I could do it is to zoom in on each of the six panels and print screen from there, resulting in six images, and I don't want to use them in that way.

I downloaded Gimp (which I'm keeping) but when I import the pdf (using "open location") with the URL of the PDF, the downloaded version doesn't have anywhere near the resolution that the image on the website does. In other words, if you use the "zoom box" on the Chronicling America site, you can get crisp resolution over one panel of the six panel image. When I try the same with either the pdf version download using adobe reader, or the GIMP import of the download, when I zoom the same way it pixelates, leading me to believe the pdf version they are allowing is fixed at a much lower resolution than the original. So I think downloading the JP2 is the only workable solution. Thanks for the offer Nyttend! However, as I said the pdf isn't viable. I'll try to figure something else out. Going to go try some JP2 google searches for a free program.--Fuhghettaboutit (talk) 14:42, 23 January 2010 (UTC)[reply]

For ImageMagick: What OS are you running on? If it is a Windows-based, all you really need is the executable, convert.exe, that comes with the download package. If you are on anything Unix-based (e.g. OS X or Linux), then yeah, welcome to free-software hell, you might as well ignore it because it'll take an entire day to compile even if you don't run into trouble compiling the secondary packages. (Am I bitter about this? Yes indeed.) --Mr.98 (talk) 15:10, 23 January 2010 (UTC)[reply]

Running Windows XP. I looked for an executable in the download but didn't see one (and already trashed the download and emptied the trash).--Fuhghettaboutit (talk) 15:55, 23 January 2010 (UTC)[reply]

I have another issue. Now. When I click on the download JP2 it tries to open using Quicktime, and what I get is a screen opening with the Quicktime logo with a question mark overlayed. How do I make it so that the program I download to open the JP2 is the actual program that is used by my computer to attempt to open the JP2 when I download it from the Chronicling America site? (yes I know, I'm needy).--Fuhghettaboutit (talk) 15:55, 23 January 2010 (UTC)[reply]

One workaround is that instead of clicking the JP2 file, right-click it, choose "Open With", and then choose whatever app you want to use instead of the QuickTime player. (BTW, I use Irfanview for all graphics conversion needs and recommend it; it works with JPEG 2000 also.) Comet Tuttle (talk) 16:47, 23 January 2010 (UTC)[reply]

I tried but it doesn't give the option for "open with". Here's a screenshot.--Fuhghettaboutit (talk) 18:35, 23 January 2010 (UTC)[reply]

You need to download it to your computer first (select "Save Link As..." from the menu shown in your screenshot). Then open the folder you saved it to, right-click the file and select "Open With..." and then pick the program you want from the submenu. —Ilmari Karonen (talk) 23:43, 23 January 2010 (UTC)[reply]

Thank you all. With all the various help I received, not only did I learn a few things, but was able to download the file in its full version and upload it in high resolution glory, here. For closure, I was able to download and use Irfanview to recognize the JP2 and convert it to a format Paint.NET/Gimp both recognize.

Please do your own homework.

Welcome to the Wikipedia Reference Desk. Your question appears to be a homework question. I apologize if this is a misinterpretation, but it is our aim here not to do people's homework for them, but to merely aid them in doing it themselves. Letting someone else do your homework does not help you learn nearly as much as doing it yourself. Please attempt to solve the problem or answer the question yourself first. If you need help with a specific part of your homework, feel free to tell us where you are stuck and ask for help. If you need help grasping the concept of a problem, by all means let us know.

It seems that you might want to read the computer virus article. The term "virus" is sometimes (incorrectly) used to describe any type of malicious computer software; really, to qualify as a virus, it needs to self-replicate. You can design such a program using a programming language and a compiler. Antivirus software uses numerous methods to prevent a virus infection - most commonly, the software has a database of known bad programs, and prevents the computer from downloading any file which contain those programs. You'll find some information about repairing a computer from malware in the malware article. Nimur (talk) 07:00, 23 January 2010 (UTC)[reply]

I have a few password protected pdf files that I want to remove the passwords from. I have the passwords. I can read these files and print them, but there is no longer any reason for them to remain protected and I'm tired of looking up passwords whenever I want to open one. I already tried printing them to a pdf creator. I don't understand why that didn't work, but it didn't. Any other ideas? 69.208.0.74 (talk) 07:21, 23 January 2010 (UTC)[reply]

Download PDFSharp. Create a tool based on the following code:

static void Unlock(String filename, String password)
{
	PdfDocument document = PdfReader.Open(filename, password, PdfDocumentOpenMode.ReadOnly);
	document.Save(filename);
}

The newly written PDF will contain all of the same contents but will not be password locked. I use this technique quite frequently. 124.214.131.55 (talk) 07:41, 23 January 2010 (UTC)[reply]

difference between html server componemts and asp.net server components .can i use the html server components in a asp.net web applications ?

HTML components are sent directly to the browser as is. ASP.NET components are converted into HTML by the server, then sent to the browser. So, no matter what component you use, they'll all end up as HTML in the end. You can mix them up. It doesn't matter.--Drknkn (talk) 18:39, 23 January 2010 (UTC)[reply]

Some trail programs allow say 30 days of use then stop working a demand payment. If the program is uninstalled, then reinstalled it still remembers that the 30 days have been used. Obviously the uninstall process isn't a complete clear of all changes; something remains in the windows system. I want to clear this "remember" information to ensure the system is cleared of ALL traces of the previously installed program. How?

It no doubt varies program by program. Usually such things are hidden in the Registry, but exactly where that info is stored, is probably different for each program. --Mr.98 (talk) 16:02, 23 January 2010 (UTC)[reply]

They deliberately leave Registry entries and small files in different places to prevent what you are proposing to do. In theory, you could edit (or restore a backup of) your registry, and delete any small data files, but you will need to find out where they all reside. Formatting your hard drive and reinstalling your operating system is a very drastic solution to your problem. Dbfirs 08:44, 24 January 2010 (UTC)[reply]

What layer in the osi model does a server work with? I would guess Session and application, but does it know anything about the other layers.--Dbjohn (talk) 16:18, 23 January 2010 (UTC)[reply]

It would depend on the type of the server (e.g., DNS, application, etc.). I think that application servers and web servers are unfamiliar with the details of the lower layers. The operating system would handle breaking up the data into packets and resolving addresses (with the aid of other servers and routers, of course). The application server would simply perform method calls using the operating system's networking API. It does not care how those methods work. It only calls them and the OS knows the individual instructions within those methods.--Drknkn (talk) 18:36, 23 January 2010 (UTC)[reply]

It's worth noting that a lot of modern "Web 2.0" servers are streaming multimedia over proprietary protocols (RTMP comes to mind). So, the server software must be aware of at least OSI layers 4 through 7 (since it's probably spewing out UDP packets with custom payloads). Most other stuff on the "web" uses TCP and HTTP, allowing the server software to only care about Layers 6 and 7. Nimur (talk) 20:08, 23 January 2010 (UTC)[reply]

None of the cited examples use a network protocol that follows the OSI model, these are all TCP/IP based systems.

Currently wide screen monitors are cheaper than the full screen computer monitors. Not only that, some stores don't stock monitors with a 4:3 aspect ratio. My own 19" acer monitor died recently and I'm using a ViewSonic widescreen TV/monitor as a makeshift screen. Using this monitor there are a couple of things that bother me. 1) some programs force the screen resolution to 800x600, 1024x768, etc. meaning it looks stretched on this widescreen. 2) this monitor does not have a way to adjust aspect ratio. Sure, I can adjust adjust the desktop resolution to make things proportional, but that ONLY works for the desktop. Yes Widescreen is how human eyes naturally see the world and its good for watching movies, but its really bad for games and programs built for 4:3 (i.e. anything older than two years). Of the wide screen monitors out there, are there kinds that can switch between 4:3 and 16:9 aspect ratios? Preferably something that can automatically adjust aspect ratio based on the input resolution. — Kjammer  ⌂ 21:39, 23 January 2010 (UTC)[reply]

Many video cards let you choose how to handle scaling when displaying a resolution lower than the LCD resolution. For instance, my nVidia driver lets me choose between "Use nVidia scaling", "Use nVidia scaling with preserved aspect ratio", "use the LCDs built-in scaling", and "do not scale". --Andreas Rejbrand (talk) 21:49, 23 January 2010 (UTC)[reply]

I think you are either out of date or confused as to how programs handle wide-screen monitors these days. Every game I run that has a 4:3 aspect ratio just puts black bars on the side—it does not warp the image. They are far more flexible than you think they are. I have a wide-screen monitor and a wide-screen laptop and have no problem at all playing older games on it. --Mr.98 (talk) 22:22, 23 January 2010 (UTC)[reply]

Don't have a widescreen monitor either, but I know some (can't recall brand) have a button on them to switch between 16:9(wide) & 4:3(normal) ratio. Some games allow you to select wide screen as well as 'standard' resolution/ratios, without any bars or distortion. --220.101.28.25 (talk) 23:42, 23 January 2010 (UTC)[reply]

Mr.98, your video drivers may be fancier than mine — my games don't do that; Warcraft 3 is an example of a game that just stretches wide to fit my monitor. Kjammer, I agree, it drives me nuts, too, that my local large-chain electronics store seems to stock 95% 1080p resolution monitors, which is just lame. I have started to buy monitors from Newegg or other online electronics retailers, but this seems to be some sort of wave of the future, unfortunately. Comet Tuttle (talk) 23:44, 23 January 2010 (UTC)[reply]

I agree, if you send a non-widescreen image to a monitor, by default it'll stretch it UNLESS: A) The video driver is set to add the black bars/keep the normal proportions (as mentioned above NVIDIA cards can do this, but it's not on by default) or B) The monitor is set to diable scaling/streching in it's options, but then it'll also introduce lines above and below too (a 1024x768 image on a 1920x1200 monitor would result in a smaller squarer image in the middle of the widescreen monitor with black borders all around).

I have a computer with 2 hard drives, one IDE drive and one SATA drive. I installed a kind of old version of Windows XP (without a slipstreamed SATA driver) in the IDE drive and now I have a fully working Windows XP, however, the SATA drive is not recognized, neither by the OS, neither (apparently) by the BIOS.

What's the problem?

Thanks in advance. 85.244.155.144 (talk) 22:19, 23 January 2010 (UTC)[reply]

Hm — if it really isn't showing up in the BIOS screen then the problem is of course irrelevant to your OS. First you need to see that thing in the BIOS. Switch the SATA drive to a different physical SATA connector on the motherboard; or disconnect the IDE drive and see if the SATA drive starts showing up; or try a different SATA cable. Comet Tuttle (talk) 23:45, 23 January 2010 (UTC)[reply]

I'm not testing right now, but I'm almost sure the computer booted from the SATA disk the last time I tried without the IDE one. Actually, the former operating system was installed on the SATA drive. Perhaps the board recognizes it and I didn't notice. Or can the IDE disk be causing some problem? 85.244.155.144 (talk) 23:57, 23 January 2010 (UTC)[reply]

Just to confirm, did you have both drives working with your previous operating system? Or is the IDE drive a new addition? If it's a new addition it might be that your motherboard supports an IDE emulation mode for SATA disks (which is what you are using) but that only works as long as you don't have something plugged into the IDE ports. If this is the case you'd need to into the BIOS and either turn off the SATA->IDE emulation (so it is truely seen as SATA and IDE) or experiment with the different physical ports. Bewarned that changing these options may result in Windows no longer booting due to the "boot drive" having changed physical location and you'd either need to reinstall again or edit the boot.ini file with another boot disc. ZX81 ^talk 00:18, 24 January 2010 (UTC)[reply]

I had both drives, however, since there was valuable information in the SATA drive and the OS was malfunctioning, I preferred to install the new operating system in the IDE drive. 85.244.155.144 (talk) 11:07, 24 January 2010 (UTC)[reply]

I have a set of speakers with the sort of cords that plug into a computer sound cord. My tv/dvd only has rca inputs. Can I connect them using some sort of adapter? I found one review saying the speakers were good except they cannot be connected to a tv easily. Is there hope for me, or should I give up and just use them with my computer? Calliopejen1 (talk) 04:27, 24 January 2010 (UTC)[reply]

If your TV only has RCA inputs, you can't connect that to a speaker. Your TV needs outputs. If it does have RCA outputs, you can buy an RCA-to-3.5mm adapter cable for anywhere from $5 to $15. This cable may be called an "A/V-to-Stereo" cable, an "RCA-to-Stereo", "RCA-to-1/8 inch", or "RCA-to-3.5mm" cable. Here's one from Amazon, and a similar one with a male 3.5mm connection. Do these look like they would plug in to the input/output combination you need? Nimur (talk) 04:36, 24 January 2010 (UTC)[reply]

The [ http://www.amazon.com/Audio-Adapter-Rca-Mini-phone-Stereo/dp/B000A3GPIS first one] looks good, but my speakers have three of the speaker cord things (black, green, and orange). Is there a cable for that? I'm so helpless because I don't know cord vocabulary. Calliopejen1 (talk) 04:43, 24 January 2010 (UTC)[reply]

Maybe you can photograph the back of the TV or DVD player; and the speakers, with cord(s). Do you need help uploading images? If there's a black/green/orange set of cables, usually this is a 5.1 system or a subwoofer connection - you'll need a source device (like a DVD player or Blu-Ray player) that supports surround sound to connect everything, but you can use the Green for just standard 2-way stereo. But I'm confused - I was under the impression you said the speakers plug into a "computer sound cord" (i.e., like a headphone jack - a 3.5mm stereo cable). Can you clearly describe or upload an image of how many speakers you have, how many cables they connect to, and what jacks you have available on the TV or DVD? Nimur (talk) 05:36, 24 January 2010 (UTC)[reply]

Okay, sorry for the confusion.... My TV has three holes. They take cords that look like this (I think these are RCA cords). My speakers are these and have three cords that look like this. I read somewhere on the internet that these plugs go into a sound card, so that's why I wrote that... They do plug into computer but I only have one speaker jack on my computer. When I plug the speakers into my computer, the black one makes the sound go to the back speakers, the orange one makes it go to the center speaker, and the green one makes it go to the front speakers.

You're trying to set the ethernet adapter to promiscuous mode and its driver is saying it can't. Promiscuous mode is rarely supported by wireless ethernet adapters (and is meaningless when the connection is encrypted) and usually doesn't work with modern wired network equipment (even the cheapest hubs really work like switches and don't send all traffic to each port). So you need to set the capture session to not use promiscuous mode. -- Finlay McWalter • Talk 15:28, 24 January 2010 (UTC)[reply]
