:Are you talking about the source code? Most flash source files are in the .fla format, which isn't text, but binary (zeros and ones). You need a flash decompiler to get those files. Some people use Flex, which is plain-text XML that you compile into Flash. But most of the time, you work on .fla files and sometimes .as files (which are plain text, but don't work without a .fla file). You need Adobe Flash Professional to open .fla files, by the way.--[[User:Drknkn|Drknkn]] ([[User talk:Drknkn|talk]]) 01:29, 15 October 2009 (UTC) |

== Quote marks will not appear until I type a second one == |
||
Hello all. I have a seemingly one-off, weird and annoying issue. I am using an HP laptop computer: |
|||
I've had a doppler loop radar gadget (or widget, if the term is preferable) on my igoogle page for months until today,centered on my hometown. Suddenly, it no longer worked as of today. As a result, I went searching for another one and either a) The gadget has been disabled and is no longer available or b) It is not a true loop radar display that shows the progression of rain etc. but rather a static display that updates perhaps every hour if I hit "refresh." Anyone else having this problem? Any explanations? Any solutions other than the NWS site? I loved having that gadget on my igoogle page!--[[User:Myersdtm|Myersdtm]] ([[User talk:Myersdtm|talk]]) 03:04, 15 October 2009 (UTC) |

:System Model HP Spectre x360 Convertible |

:Version 10.0.19045 |
|||
:Build 19045 |
|||
Every time I type a quote mark on this computer (or an apostrophe using the same keyboard key without shifting) nothing happens. It is only when I invoke the character key a ''second time'' (in a row, without moving the cursor) that anything happens, which is that, only then, TWO quote marks appear. I then I have to delete one of them. Same thing for apostrophes, though I use quotes far more frequently. This happens anywhere I attempt to type the character, including when I placed this one " right now. Please note that the key is not gummed up or anything, it always works to place the two after I type the character the second time. Any ideas? |

: What happens if you type a single <TT>'</tt> or <TT>"</tt>, followed by some other character, like a letter? |
|||
: It sounds like you're in some strange mode which is attempting to interpret various multi-keystroke sequences. Those can be perfectly ordinary — for example, as you may know, on a Mac you can type Option-U to get a bare umlaut, which when you then type a letter like A or U combines with it to form Ä or Ü. But obviously these " and ' sequences you're encountering are bizarre and unwanted! (I've never heard of combining sequences starting with " or ', either.) |
|||
: My guess is that these sequences are defined for the convenience of typists in some language other than English. I would go to the relevant control panel — perhaps "Keyboard", although under Windows I'm not sure — and make sure you've got English specified as your language, with no funny extra options specified. —[[User:scs|scs]] ([[User talk:scs|talk]]) 22:10, 11 December 2024 (UTC) |

|||
::Yes you're right. When you're on the international keyboard (or other non-English one) if you type a quote and then a vowel you get an umlaut. With this keyboard layout the first time you press a quote key it will not type it, and you have to press it twice to type a quote. |
|||
::On Windows 10, on the bottom right, to the left of the date and time, there is an area where you can click to change the keyboard layout. For the international keyboard it is "ENG INTL". If you click it you can change to the normal keyboard, "ENG" or "ENG US" or whatever you prefer. ―<span style="font-family:Poppins, Helvetica, Sans-serif;">[[User:Panamitsu|Panamitsu]]</span> [[User_talk:Panamitsu|(talk)]] 22:23, 11 December 2024 (UTC) |

::See [[dead key]]. I suppose your system is configured to see ' and " as dead keys, producing no direct output, but combining with the next character you type to create a letter with [[acute accent]] or [[two dots (diacritic)|two dots]]. I haven't used Windows since XP days, but I suppose that if the following character doesn't accept those diacritics, the ' or " is inserted after all. Try switching to a different keyboard layout.

: Have you tried a {{key|"|space}} sequence? I've seen such behavior of a keyboard in Windows when working in a language with diacritic letters. It simulates old typewriter - hit a diacritic symbol first, which gets printed with no carriage move, then hit a letter, which gets printed at the same place and then a carriage advances to a next position. Following this mode you hit a diacritic + space sequence to get a diacritic symbol alone. --[[User:CiaPan|CiaPan]] ([[User talk:CiaPan|talk]]) 15:38, 12 December 2024 (UTC) |

===Cursor Jumping Randomly=== |
|||
Sometimes when I am typing in a Word document or editing Wikipedia in a source window, I discover that the cursor isn't where I think it should be. The cursor has jumped to somewhere else on the screen, apparently randomly. I have to do a Ctrl-Z to undo what I typed in the wrong place, and then move the cursor back to where I want it. If this is caused by line noise, how do I minimize the impact? How likely is that a new mouse would resolve the problem? Are there any settings that I should diddle with? |

Yesterday I developed this bizarre new problem: Powerpoint (2003) runs, but appears to be running in some other display space. Keyboard commands work, but I can't see anything. I can switch between applications, bring Powerpoint into focus, and even pull down menus... but I can't see the Powerpoint window other than those menus. The slideshow mode works fine, however. On starting Powerpoint, the splash screen flashes on for a fraction of a second, and then vanishes off into its mystery display space. |

A picture illustrates the problem. Here's Powerpoint running and in focus (note that it is highlighted on the taskbar) As you see, I can pull down menus by using the appropriate key combinations; note that all menus start at the top left of the screen (ordinarily the menu shown here would be docked to the top menu bar somewhere in the top middle of the screen): [http://tinypic.com/r/9jlid5/4] |

== Online game lagging == |

Is there any way ISP's can fix this by providing more bandwidth?[[User:Accdude92|Accdude92]] ([[User talk:Accdude92|talk]]) ([[User:Accdude92/guestbook|sign]]) 13:39, 15 October 2009 (UTC) |
|||
:"Lag" can be caused by many things, including network latency, game server compute-overload, your CPU or graphics card overload, etc. If network latency (specifically, between your system and the server) is the bottleneck, then increasing the bandwidth from your ISP might reduce the lag that you experience. Whether this is possible depends on the technical and economic situation of your ISP in your area. [[User:Nimur|Nimur]] ([[User talk:Nimur|talk]]) 13:51, 15 October 2009 (UTC) |
|||
::You can't always reduce latency by increasing bandwidth. If a network link is congested (too busy), then increasing bandwidth will reduce latency. But if you're just trying to communicate with a server on the other side of the planet, all the bandwidth in the world will not bring your latency down -- the speed of light is your foe, not congestion. --[[User:Fubar Obfusco|FOo]] ([[User talk:Fubar Obfusco|talk]]) 17:02, 15 October 2009 (UTC) |
|||
: "Lag" is a kinda fuzzy term - "Bandwidth" and "Latency" are better precisely because their meanings don't overlap. Consider, for example, if you want to send a LOT of data to a friend on the other side of town. You could send it over the Internet - or you could write it onto a bunch of memory cards, put them into the back of your car - and drive over to your friends house. Now - the amount of data you can cram into the back of your car in micro-xD memory cards is spectacular - a petabyte maybe. The amount of time it would take to send a petabyte over the Internet would be measured in years! So the '''bandwidth''' of your car is vastly better than the Internet. But the '''latency''' of your car is awful - it takes half an hour to get across town even if you only need to send one byte! So if you want to send a 10 line email - then, because the latency, the Internet is a better choice. (See: [[Sneakernet]] and a real-world experiment to prove that a carrier pidgeon with a memory stick strapped to it's leg had better bandwidth than the [[Telkom]] ISP!) |
|||
: The amount of "Lag" in the system is composed in part by a lack of bandwidth and in part by too much latency. When you are waiting for (say) a movie to download - then certainly a lack of bandwidth is the most likely reason it's lagging your expectations. But if you clicked on a link to a small page on a (mostly) text-only web site like the one you're reading now - then any lag is most likely due to a latency - and increasing the available bandwidth probably wouldn't help much...just as carrying that 10 line email across town isn't going to go any quicker if you drive it there in your car - or in an 18 wheel truck - because while the truck has much better bandwidth than your car - it's irrelevent because they both have the same horrible latency. |

== What to do with a Toshiba Satellite 105CS? == |
|||
I've recently been given a Toshiba Satellite 105CS. This is a very old laptop: Pentium 75Mhz, 16Kb cache, 500 Mb hard drive, no CD, 1 3.5" floppy drive, and only 8 MB of RAM (not a typo; 8192 kilobytes!). There's also no OS installed. There is a dual PC card slot, and I received with it a 28.8 kbps FAX/modem card. |
|||
I'm scratching my head about what to do with this beast '''without spending money'''. Yes, I could trash/recycle it, but I'd rather try to do something useful or fun. I'd love to learn to work with a flavor of Linux (I worked with MS-DOS and lived through Win3.1, Win95, Win98, Win2K, WinXP. Before DOS I worked with [[RT-11]] and even [[CP/M]]). However, I have available a floppy-based install for MS-DOS 6.22, and a CD for Win2K that I'm not currently using. I may even have an old Win98 installation. And I have the (increasing rare) PC with a 3.5 floppy, so I can write to those. And, of course, access to the Internet. |

This directory, <code>C:\ErdUndoCache</code> (on a windows system, obviously) hold a lot of "stuff" on my system, which I'd like to clean up, and I can't figure out which application owns & operates it. Google searches for ErdUndoCache bury me in pages of HiJackThis logs, which make no sense. |

::::Specific ports are not inherently "more risky" - but if you pick a port which is commonly used to host another widespread software service, you might find statistically more random "probes" by random drive-by portscanners. Your Java program can verify the IP of who is connecting - so you can use specific-host-only connections (if you trust a specific IP, e.g. your parents' PC); the IP connecting to you can not be spoofed (unless your parents' PC is a "man in the middle" proxying somebody else's attack). You can use a Secure Socket in Java, and you can implement any of a variety of custom authorization verification handshaking protocols. It's very unlikely that an automated port scanner would guess a particular long authentication byte sequence "password" - which you could send in plain-text, or hash against the current UTC time and host IP, to make it more secure.

: Home-brewing your own network protocol generally isn't necessary, and may open up security problems you haven't considered. I'd generally recommend running a secure-shell server like [[OpenSSH]] (on a non-standard port, so you don't have to look at so much port-knocking noise in the logs). With that you can tunnel anything you want, from windows and unix networking protocols to remote screen protocols link VNC; and if you really need to write your own protocol, it's probably easier to write a non-secured version of it, and tunnel that through SSH too. -- [[User:Finlay McWalter|Finlay McWalter]] • [[User talk:Finlay McWalter|Talk]] 21:13, 16 October 2009 (UTC) |

- While I'm here, I have another question. I always liked the battle system in FFT and was wondering if there was a program that would let you set up the characters, conditions, and terrains and have a multiplayer battle in a similair fashion; namely, could one get something like the FFT battle engine, but set it up so that it is two players without computer controlled characters? If this is not possible, how hard would it be to program something like this? What would be a good language to do it in? (I've often tossed around the idea of making my own, I just don't have that much experience with game programming; though I do have experience with other areas.

:The big difference between these two motherboards is one supports DDR3 and the other DDR2. As DDR2 is still significantly cheaper then DDR3 I would recommend you stick with it. You're unlikely to see any performance difference in the vast majority of real world applications e.g. [http://www.anandtech.com/memory/showdoc.aspx?i=2989] [http://www.tomshardware.com/forum/255223-30-ddr2-ddr3-core] so the only real benefit would be being able to use the RAM in a future DDR3 computer but given the price that's not likely to be a big advantage and the advantage is the ability to upgrade the RAM in the future for a reasonable price (since DDR3 will eventually overtake DDR2 in price and then will get cheaper) but again if you get 4GB now (and given the price there's little reason not to) there's not likely to be any real reason to upgrade in the future I would expect.

This is such a simple question but I have a problem that's driving me BONKERS. |
|||
When I am using excel, very frequently when I click on a cell or a line, it will select 2, 3, or 4 cells/lines below it. I can't get it to stop doing this. It seems to happen at random and has nothing to do with the doc itself, the formatting, previous actions, or anything else. It will keep happening for 2-3 minutes and then suddenly it will stop and I can select 1 cell/line again. My colleagues report this issue all the time and no one has a clue why it happens or how to stop it. |

It happens with any and all docs, including those created by other sources and other offices. It happens on multiple computers. Definitely has nothing to do with merges. I could create a document right now thats just a list of my friend's names, and it might happen. Or it might not. No clear pattern. It seems that many of my colleagues just deal with it and treat it like "one of those things". Excel is always trying to "help" you by doing frustrating things automatically, such as creating formulas where you don't want them. I am assuming that's what's happening here. |

* Gohome00, I would bet that this has something to do with your typing or clicking habits. If you are holding down SHIFT or CTRL when you click it will select more then one cell at a time. SHIFT selects every sell between the initial cell and the finial cell in a square shape, CTRL selects the initial cell and the clicked cell. If the mouse is moving when you click it's possible to select two or more cells at a time. If you dial down the mouse sensitivity (speed) it might prevent this.

:: These services certainly exist - but are really expensive. For a one-off, they are the cheapest (and only) route. But if you need to do this a lot, you might also like to look at the "[[RepRap]]" project and also things like the [[MakerBot]]. These small machines can be built for relatively low cost ([http://store.makerbot.com/cupcake-cnc.html $750 in kit-form] - about $400 if you make it yourself from scratch) and it will do exactly what you're asking. The [[RepRap]] machine can even make all of the plastic parts you need to make another RepRap machine! The business end looks like a hot-melt glue gun (although it's hotter and a little more sophisticated) and a pair of motors drives that around in two axes to 'draw' a thin layer of plastic representing a cross-section of your object. A third motor moves the plastic depositor up and down vertically so that the model can be built up layer by layer. It's slow - it could take an hour or more to make even a pretty small object - and there are rather severe restrictions on the size of objects that you can make with it - but compared to the commercial services, it would probably pay for itself after making maybe just a dozen objects. |
|||
:: Alternatively if your objects don't have under-cuts - and if you're at all good with tools, you could do as I did and build a [http://www.instructables.com/id/How-to-Make-a-Three-Axis-CNC-Machine-Cheaply-and-/ three Axis milling machine] for about $200. I built mine over several weekends using MDF for the major structural parts, aluminium channels and roller-blade bearings as the guide-rails and three stepper motors with long lead-screws to drive a 2hp router motor in the X, Y and Z directions. I used a couple of [[Arduino]] computers to control it using instructions written to an SD memory card - so it doesn't tie up my PC for hours at time. Mine will carve wood and some sorts of plastic pretty efficiently at sizes up to 4'x3'x9" - and with precision of about a millimeter or so. It can also cut metal - but you have to go very slowly and lubricate the cutting surface - which is a major pain. You can drive it from all sorts of 3D file formats from existing OpenSourced software. It doesn't have the versatility of the plastic deposition machines like RepRap - but it's cheap to make and can produce much larger and more robust work-pieces than those plastic deposition machines. My longer term plan is to use the CNC milling machine to make the parts for my own design of 3D printer...and to make a smaller five-axis CNC machine with a Dremel as the cutting tool. That machine would be able to make under-cuts and such like. |

== slow file copying speed == |
|||
I have a Thinkpad T61 laptop running Ubuntu 8.04. The laptop has an internal SATA hard drive and also a plug-in bay with a second hard drive (you can put an optical drive there instead if you want). The second HD is also SATA but I'm pretty sure the plug-in bay has a SATA-PATA bridge inside. Both drives have ext3 file systems. Anyway, I tried copying a 4gb .iso file from the internal drive to the plug-in drive and after a while, the transfer slowed to around 5MB/sec, which just seems pathetic. Copying from the internal drive to an external USB drive gets around 5x that speed (though much more cpu load). It's not the speed of the PATA bus either. I unmounted and remounted the plug-in drive, then catted the copied file to /dev/null and got about 60MB/sec transfer. So why was the original copying so slow? It was slow whether I used cp, dd, or rsync. The computer has tons of ram and was not heavily loaded at the time of the tests. Any ideas?

|||
:Those rates (5MB/sec and 60 MB/sec) very closely match the transfer speeds for USB 1.1 and 2.0. Probably, for whatever reason, the plug-in drive was originally only recognized as a USB 1.x compliant device; on reconnecting, the correct driver was detected and loaded, and the device functioned with full USB 2.0 speed.

|||
:::I think I got it - it was slow between the internal SATA drive and the bay-drive - probably because these devices share the same [[southbridge]]/[[Conventional PCI|peripheral controller]]; but the data can not go directly from disk-drive-1 to disk-drive-2 (it must [[Direct Memory Access|go to main memory]], at least - and may have to actually use the CPU). Thus the memory-northbridge-southbridge bandwidth is split in half. The case of an external USB drive does not share the PCI bus - so this bandwidth is not bottlenecked, and the full USB transfer speed is possible. There are still a few curious issues with the numbers; you could benchmark a lot more to really narrow down where the real worst-case performance happens to locate what the bottleneck is (but it may not be worthwhile, depending on how often you need high performance data transfer).

:Whoa, something weird is going on, catting the file from the INTERNAL drive to /dev/null just took 16 minutes (4 MB/sec). I wonder if something is wrong with the internal drive. I'm trying another copy with a different large file. Just last night I backed up the drive to an external USB 2.0 drive and got 20+ MB/sec transfer. But I see no error messages in "dmesg" or syslog. Anyway, there are 3 drives: 1) internal SATA, should be directly on PCI bus and fast. 2) Plug-in bay drive, on SATA-PATA bridge that should be on the bus; 3) external USB 2.0 drive. There is also a 4th possibility, which is that I have an ExpressCard eSATA adapter (plugs into internal PCIe if I understand properly) that I can connect an external drive to, but I haven't tried that yet. Right now, something seems flat-out wrong with the internal drive, like maybe it has gotten in some weird DMA mode. I wonder how to diagnose this.

== Rebol v Python - which is better? == |
|||
I've only programmed with basic and logo previously, and I want to learn a more up to date language that will allow me to interact with the web and with Windows or Linux. Although the Wikipedia article about [[Rebol]] is a very dry formal description (*) that does not do the language justice and makes it appear totally unsuitable for the casual user or beginner, the tutorials here http://www.musiclessonz.com/rebol_tutorial.html make the language very alluring. (* Its as if the [[Motorcycle]] article was like this: "A /motorcycle/ is an electro-mechanical device which transforms the chemical energy of hydrocarbons into kinetic energy...."). |
|||
Can anyone put the case for Python and say why I should learn Python rather than Rebol? I am only going to learn to use one language. Speed of learning and quick programming (not program speed) are what is important to me. It would only be for ocassional casual use. It looks like Rebol can do things in a single line of code (see http://www.rebol.com/oneliners.html for example) that would take pages in other languages, and also that I can do web things with it that would be too complicated for me to attempt in other languages.

Thanks for your replies but sorry I think that is less than convincing evidence for the superiority of Python. Python may have a big-user base prescence on the web because getting it to do some things are difficult/complicated, while with Rebol these same thing may only require one or two command words.

::When I was using Windows I'd put command programs in a single directory (e.g. e:\utils) and put that directory in the path. Command-line programs are very useful and the great majority of them have few files that are really needed, so it's easy for a dozen or more programs to coexist in the same directory.

Sorry I don't know the answer to your specific question but I imagine that these "next page" links have an easily identifiable set of filenames, and if you can't easily get wget to get these filenames and little more, then simply get the whole of the relevant section of the site and then delete the stuff that's of no interest to you. -- [[User:Hoary|Hoary]] ([[User talk:Hoary|talk]]) 02:19, 17 October 2009 (UTC) |

== Converting WAV to MIDI == |
|||
I have several WAV sound files that I need to convert into MIDI format. What's a free program that will do this? Mediaconverter.org doesn't convert to or from MIDIs for some reason. --[[Special:Contributions/75.10.49.150|75.10.49.150]] ([[User talk:75.10.49.150|talk]]) 22:11, 16 October 2009 (UTC) |

:A WAV file contains samples of the sound wave, several thousands per second. Consequently, any sound may be represented as a WAV data file. A MIDI file, however, is merely a sequence of instrument names, notes, and velocities, and thus only (relatively) simple music may be represented as a MIDI file. Among other things, song and general sound effects cannot be represented as a sequence of notes. In fact, you can compare WAV files to bitmap images, and MIDI files to vector images. A bitmap image contains the colour value at each pixel (millions of them per image), and a vector image file contains only a list of objects (circle, line, etc.) and their attributes (colour, line width, etc.). Thus it is easy to convert a MIDI file to a WAV file, and a vector image to a bitmap image, but it is extremely difficult to do it in the other direction. --[[User:Andreas Rejbrand|Andreas Rejbrand]] ([[User talk:Andreas Rejbrand|talk]]) 22:16, 16 October 2009 (UTC) |

:::Yes, you might want to consider learning about [[Asynchronous I/O]] for some background theory, and [[Thread (computer science)|creating a separate thread]] for the audio I/O. [http://java.sun.com/javase/6/docs/enwiki/api/java/lang/Thread.html Java Thread]s are basically built into the language, and are fairly straightforward - you will need to instantiate a thread and and provide it with a run() function that performs the audio playback. If you are using the newest [http://java.sun.com/j2se/1.5.0/docs/enwiki/api/javax/sound/sampled/Clip.html Sampled Sound in javax.sound.sampled], then the default start() and stop() methods are already asynchronous (threaded), so you don't have to do this manually.

:WAV to MIDI is essentially impossible. WAV is like the recording of an orchestra playing - MIDI is like the printed score sheets that the musicians were reading from at the time. There is software (and hardware) that can extract note information from the pitch of the music - but it's really patchy and doesn't work for anything but simplest single-instrument recordings.

: The obvious first thing to try is to connect to your router with an ethernet cable; this will tell you whether the problem is a local wireless problem, or a problem with the internet connection as a whole. Diagnosis and fixes for these two kinds of error are often very <s>difficult</s>edit: different. In the meantime, stop all peer-to-peer programs like Bittorrent; in my experience consumer DSL routers can inexplicably exhaust some internal resource, and become fatally horked when confronted with the torrent (sic) of traffic such programs throw at them. -- [[User:Finlay McWalter|Finlay McWalter]] • [[User talk:Finlay McWalter|Talk]] 22:42, 16 October 2009 (UTC) |

:(e/c) Thanks for providing a useful amount of information. If the problem turns out to be with the WiFi, there are several fixes you can try. Obviously, you need to be within range for it to work. What is the signal strength as reported by Windows? A recently purchased wireless router should have the strength to cover a two- or three-storey house. Piggybacking on the neighbour's WiFi does not usually get the speed or stability that you want. Do you know the brand and model number of your router? Other quick fixes: if there are many other wireless networks in the area, then you might want to change the broadcast channel. Most routers default to channel 6 - try changing to channel 1 or 11. Some cordless phones and microwaves also emit the same frequency (~2.4 GHz). For me, changing to channel 11 solved an interference problem with a neighbour's router. It's all trial-and-error. If possible, you can move your router to a better location, away from the computer and in the centre of the range of which you wish to connect to the network.

:I used that AT&T service on my wife's machine for a while - it was awful. As you say - poor bandwidth, patchy connections, generally a total disaster. I carefully documented the problems - worked with them patiently for a month while they tried to fix it, making all sorts of ridiculous claims that it was my computer (I used three different one - they couldn't all be at fault) - they claimed that "Windows needs to be rebooted once a day to keep the networking reliable" (possibly reasonable advice - but I was using Linux!), etc, etc. Then I demanded (and got) all of my money back for the whole 60 days I'd been using it and the refunded the price of my network adapter too. I switched to RoadRunner - things have been working just fine since then. So I don't think you should blame XP or the wireless adapter until you've hassled the AT&T helpline a bunch of times. It's very likely to be the AT&T service. [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 03:48, 17 October 2009 (UTC) |

:One diagnostic thing you might try out is to see how the connection works when "wired" (you should probably be able to connect to your wireless router with an ethernet cable). Is it faster?

: I'll guess that your are accessing your email account using the [[POP3]] protocol (it's in the account settings screen in Outlook). Very often people's POP3 clients (that's Outlook in your case) are configured to download emails and ''remove'' them from the mail server. You can configure the client to download and ''not'' remove the mail server's copy. That way Both machines can see it (I don't have outlook to hand so I don't know the precise option you'll use). A downside of this is that mail will then build up in your mail server, so you may need to be more diligent about tidying it up yourself (so you don't exceed any quota your ISP may apply). As an alternative to POP3, you may be able to use the [[IMAP]] protocol instead, which is better suited for sharing one email account between multiple machines (you can, for example, create subfolders on the mail server and then file mail as appropriate - and all the email clients see the change almost instantly). -- [[User:Finlay McWalter|Finlay McWalter]] • [[User talk:Finlay McWalter|Talk]] 23:14, 16 October 2009 (UTC) |

One downside to this juggling act is that the secondary computer won't have access to any e-mails the first computer has downloaded. One alternative, OP, is to set up [[Remote Desktop Services|Windows Remote Desktop]] or [[VNC]] so your 2nd computer merely logs into the 1st computer and sees whatever you'd see on the screen of the first computer.

:You didn't mention the key point, what video codec is the video? For 1080 this would commonly be h264 but doesn't have to be. Also you didn't mention what your current specs are in particular the current processor and motherboard (or at least whether it has a PCIe16 slot available). Most dual core processors, should be able to handle even fairly complicated h264 especially with an efficient codec like h264. However if you already have a decent processor and your computer has a PCIe16 slot available then simply getting a modern ATI or Nvidia card which supports full h264 (and preferably VC-1) bitstreaming would be enough for most files (although a few aren't supported but most nowadays are 'DXVA compatible') and likely to be cheaper, however getting it to work on Windows XP may be a little more difficult then Windows Vista. mHz is an exceptionally poor measure, see [[mHz myth]]. If you are set on getting a new computer, I would suggest a decent dual core (say an E5200/5300 or any Athlon II X2 or Athlon X2 7xxx) and a GPU supporting bitstreaming would sufficiently cover whatever you need [[User:Nil Einne|Nil Einne]] ([[User talk:Nil Einne|talk]]) 11:01, 17 October 2009 (UTC) |

I have Sun (not openjre) javaws on Fedora 11 without SELinux enabled. When I run a jnlp app, my keyboard is disabled on the app. Googling hasn't turned up anything useful.

: I can only say that Sun JavaWS on Ubuntu 9.04 properly opens and displays JNLP apps and delivers keyboard events to them normally. It doesn't make sense for a security property to allow AWT/Swing objects to appear on screen, but to not deliver keyboard events to them, so I really doubt there's a security property that is so granular. If I were to guess, I'd hazard that it's a bad interaction between the window manager and the toplevel window, in that somehow the java app doesn't get focus properly, or doesn't think it does. Try, as a first instance, running the SwingSet2 demo from [http://java.sun.com/javase/technologies/desktop/javawebstart/demos.html Sun's demo page] and changing the Look-and-feel (that really shouldn't matter, but clearly something is wrong). -- [[User:Finlay McWalter|Finlay McWalter]] • [[User talk:Finlay McWalter|Talk]] 15:22, 17 October 2009 (UTC) |

: There are rather more sophisticated task-manager-like programs, like [[Process Explorer]], but they kill processes in fundamentally the same way that Task Manager does (and so really shouldn't do anything better). The only thing I can suggest is that you're actually killing a [[subprocess]] of firefox, and leaving the parent intact.

:I think it isn't possible but I'm not sure. It is better to have the functions in a file, and then import them. A proper editor will let you run an inferior python shell inside an editor buffer and directly load python functions to it from other buffers, eg [[GNU Emacs|emacs]] does this with C-M-x. Emacs or any other decent editor would also give you [[syntax highlighting]] and autoindenting and more.

If I have a binary file that I want to print it out as hex data in a terminal, you can just use the "[[od (Unix)|od]] -h" command.

:Just <code>echo -e '\x''##''\x''##''' >file</code> should work, if it's not a problem to put the data on the command line in that format. If you'd rather, <code>perl -e 'while(read STDIN,$_,2) {print chr hex;}'</code> will read a ''solid'' block of hex from stdin (no spaces or newlines) and write the corresponding data on stdout.

- To avoid videos with crocheting Chinese ladies and such – if that's not your thing – make sure the video is from the original channel and not some pirated and hacked video. The name of the channel (such as Eyewitness News ABC7NY, Jimmy Kimmel Live, ESPN MBL, ...) is given below the title of the video.

[edit]Quote marks will not appear until I type a second one
[edit]Hello all. I have a seemingly one-off, weird and annoying issue. I am using an HP laptop computer:
- OS Name Microsoft Windows 10 Home
- System Model HP Spectre x360 Convertible
- Version 10.0.19045
- Build 19045
Every time I type a quote mark on this computer (or an apostrophe using the same keyboard key without shifting) nothing happens. It is only when I invoke the character key a second time (in a row, without moving the cursor) that anything happens, which is that, only then, TWO quote marks appear. I then I have to delete one of them. Same thing for apostrophes, though I use quotes far more frequently. This happens anywhere I attempt to type the character, including when I placed this one " right now. Please note that the key is not gummed up or anything, it always works to place the two after I type the character the second time. Any ideas? --68.129.153.226 (talk) 17:23, 11 December 2024 (UTC)
- When did this start happening? Has it always been like this? If not, what changed? Be honest. MinorProphet (talk) 20:29, 11 December 2024 (UTC)
- My 13-year old Mac Mini has stopped working. (I have already purchased a new computer, arriving in about two weeks.) I thus borrowed this HP from my sister a week ago, whereupon I discovered this issue. I thus have no idea of the timeline of the problem.--68.129.153.226 (talk) 21:07, 11 December 2024 (UTC)
- What happens if you type a single ' or ", followed by some other character, like a letter?
- It sounds like you're in some strange mode which is attempting to interpret various multi-keystroke sequences. Those can be perfectly ordinary — for example, as you may know, on a Mac you can type Option-U to get a bare umlaut, which when you then type a letter like A or U combines with it to form Ä or Ü. But obviously these " and ' sequences you're encountering are bizarre and unwanted! (I've never heard of combining sequences starting with " or ', either.)
- My guess is that these sequences are defined for the convenience of typists in some language other than English. I would go to the relevant control panel — perhaps "Keyboard", although under Windows I'm not sure — and make sure you've got English specified as your language, with no funny extra options specified. —scs (talk) 22:10, 11 December 2024 (UTC)
- Per the below, it sounds like you might well see different behavior depending on whether you type the " or ' followed by a vowel like A or U, versus a consonant like B or S. —scs (talk) 22:16, 12 December 2024 (UTC)
- Yes you're right. When you're on the international keyboard (or other non-English one) if you type a quote and then a vowel you get an umlaut. With this keyboard layout the first time you press a quote key it will not type it, and you have to press it twice to type a quote.
- On Windows 10, on the bottom right, to the left of the date and time, there is an area where you can click to change the keyboard layout. For the international keyboard it is "ENG INTL". If you click it you can change to the normal keyboard, "ENG" or "ENG US" or whatever you prefer. ―Panamitsu (talk) 22:23, 11 December 2024 (UTC)
- See dead key. I suppose your system is configured to see ' and " as dead keys, producing no direct output, but combining with the next character you type to create a letter with acute accent or two dots. I haven't used Windows since XP days, but I suppose that if the following character doesn't accept those diacritics, the ' or " is inserted after all. Try switching to a different keyboard layout. PiusImpavidus (talk) 10:37, 12 December 2024 (UTC)
- Have you tried a "+space sequence? I've seen such behavior of a keyboard in Windows when working in a language with diacritic letters. It simulates old typewriter - hit a diacritic symbol first, which gets printed with no carriage move, then hit a letter, which gets printed at the same place and then a carriage advances to a next position. Following this mode you hit a diacritic + space sequence to get a diacritic symbol alone. --CiaPan (talk) 15:38, 12 December 2024 (UTC)
- Well, 68.129.153.226, we're all agog to know whether any of our suggestions have worked. Be honest. MinorProphet (talk) 17:35, 13 December 2024 (UTC)
- I am on Windows 10 on Dell laptop. I have experienced this behavior and I suspect it started after some OS update.
- But note that, when you wish to include anything in double/single quote, you must continue to type as usual. The double/single quote becomes visible only after you type any following character (not just single/double quote).
- You may be already aware of it, but I thought if you don't know, it will be less frustrating experience once you know how it works. manya (talk) 06:04, 16 December 2024 (UTC)

[edit]Questions About New Laptop Computer
[edit]My old laptop computer developed problems with the power, so that it wouldn't start when connected to regular line current. It would start when connected to high-amperage current in an electronics store, but that wasn't useful, and it was time to replace it after five years. I now have some questions about problems with a new laptop computer. The new laptop computer is an HP running Windows 11. Robert McClenon (talk) 04:43, 15 December 2024 (UTC)
Cursor Jumping Randomly
[edit]Sometimes when I am typing in a Word document or editing Wikipedia in a source window, I discover that the cursor isn't where I think it should be. The cursor has jumped to somewhere else on the screen, apparently randomly. I have to do a Ctrl-Z to undo what I typed in the wrong place, and then move the cursor back to where I want it. If this is caused by line noise, how do I minimize the impact? How likely is that a new mouse would resolve the problem? Are there any settings that I should diddle with? Robert McClenon (talk) 04:43, 15 December 2024 (UTC)
- First thing I would do is give the mouse and mousepad a good clean and disconnect and reconnect it. Shantavira|feed me 09:14, 15 December 2024 (UTC)
- Possibly due to your hand brushing the trackpad while typing. If you have a mouse, you could experiment with disabling the trackpad: how to disable touchpad on hp laptop. Or even just try turning it off while typing. This erratic caret jumping used to happen to me a lot, too, when my laptop was new, until I found the key to disable the trackpad.
- The term caret or insertion point is useful to exclude the mouse cursor (the pointer) from searches. Card Zero (talk) 12:54, 15 December 2024 (UTC)
- Thank you, User:Card Zero. I disabled the touchpad. For users who always use a mouse, the touchpad is a complication. Robert McClenon (talk) 19:06, 15 December 2024 (UTC)
- I now have a possibly useless question. The documentation referred to an option that disables the touchpad when there is a mouse, but the only option that I found in the settings is the option that always disables the touchpad. I would like to specify that the touchpad is disabled when there is a mouse, and enable it if there is no mouse. This makes very little difference because I will always use a mouse. Is it possible that that option isn't available on my computer? This isn't important. Robert McClenon (talk) 02:38, 17 December 2024 (UTC)

Network File Sharing
[edit]With the old laptop, I had set up network file sharing, so that the laptop computer could view and edit files in shared folders on my desktop computer, a Dell, also running Windows 11, if they were both within range of my wireless router (and the desktop computer always is). The desktop computer could also access files in shared folders on the laptop, if the laptop was I have tried to set up network file sharing with the new laptop computer. I tried calling the technical support offered by the electronics chain that I bought the computers from, and I made seven calls to them, none of which worked, and I have concluded that their technical support people don't know what they are doing, and, worse, don't know the limits of their knowledge. Does anyone have advice on a book that will tell me how to set up network file sharing with Windows 11, that has neither too little nor too much information for a retired database engineer? Robert McClenon (talk) 04:43, 15 December 2024 (UTC)
- @Robert McClenon Did you try this? TheTechie@enwiki (she/they | talk) 20:21, 16 December 2024 (UTC)
- User:TheTechie - Thank you. That describes the basics, and describes what I had done successfully with the previous laptop computer. I need either a much greater level of detail, or a troubleshooting guide, or something like that. That was helpful in that it doesn't point out anything that I am doing wrong.
