: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. Pirated videos come from an unfamiliar channel; other than that, everything looks the same as the legit video. --[[User talk:Lambiam#top|Lambiam]] 07:35, 10 December 2024 (UTC) |

== Cheapest pocket 'computer' == |
|||
= December 11 = |
|||
What would be the cheapest pocket-sized or less self-contained computing device? Some constraints: it must 1) have some kind of alpha-numeric keyboard - a touch-screen keyboard might do. 2) have a display that can at least show text and numbers. 3) have some high level programming language 4) be able to save data or programs 5) be able to trabsfer data and programs to and from a computer. Thanks. (As paper LCDs are now possible, I hope that one day soon it will soon be possible to buy a pocket computer for a few pounds or dollars.)

Hello all. I have a seemingly one-off, weird and annoying issue. I am using an HP laptop computer: |
|||
: Personally, I'm still waiting for my [[OpenPandora]]. Graphing calculators like the TI-92 sell used for under $40 on ebay. They've got a weird form factor, though. You might go for an older PalmOS machine. They don't come native with built-in programming tools, but you can get C compilers and stuff.

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".

::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) |

I'm OK with software, but I know nothing at all about hardware, so when I decided to build a computer I was forced to turn to the Internet. Off a suggested parts list for a budget gaming computer, I got most of the following parts, although a few were no longer available so I had to try to find an alternative.

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.

===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? |

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).

::::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) |

::In Java, wrapping the protocol in SSL would be possible using [http://java.sun.com/javase/technologies/security/ Security], e.g. the [http://java.sun.com/j2se/1.4.2/docs/enwiki/api/javax/net/ssl/SSLSocket.html SSLSocket] (with SSL implemented by Sun, not by OpenSSH).

I was wondering, are the complexity classes of algorithms used to solve the 3-Sat descion problem determined based upon the number of actual variables or the number of expressions? For example, would the input size of (a + !a + b) AND (b + !b + a) AND (a + a + a) be 2 since {a,b} has 2 elements or 3 since 3 expressions are being conjuncted? (Obvbiously, this example can be very easily reduced down to fewer expressions, etc.) [[Special:Contributions/66.202.66.78|66.202.66.78]] ([[User talk:66.202.66.78|talk]]) 07:37, 16 October 2009 (UTC) |

== Final Fantasy Tactics == |

- 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. Note: I really don't care about the quality of the graphics, just the system.) Actually, while here, I would like to ask the same question, only with regards to FF7 Chocobo racing portion from the Golden Saucer. (Again, this doesn't need to be an exact duplicate, just something related that I could customize and, possibly, mess around with the actual code) Thanks:) [[Special:Contributions/66.202.66.78|66.202.66.78]] ([[User talk:66.202.66.78|talk]]) 07:45, 16 October 2009 (UTC) |

: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.

::::It depends on your budget but I would regard 25% (actually probably more then that from what I've seen) as significantly more expensive that you have to ask yourself what for? In this case, a big question is future proof against what? As I've mentioned, given the current price of RAM, the advantage of being able to use your RAM in a future computer is IMHO pretty much worthless (particularly since in most places you could easily sell your DDR2 RAM for a fair amount if it comes down to that). So the only real advantage which I also mentioned would be being able to upgrade RAM in the future (any decent RAM should have a lifetime warranty so having to replace broken RAM is not an issue) at a more decent price and with larger sticks (since it is unlikely we will see 4gb DDR2 sticks but I would expect 4gb DDR3 sticks to eventually take hold and become a recent price). If you are a gamer, simulatenous edit very large photos, do CAD or 3D work, edit HDTV, run a database or otherwise may really need such a large amount of RAM in the future then it may be worth considering. But in reality, the average user doesn't really need even 4gb nowadays, the only reason I recommend it is because it's the only sensible option (well unless you're looking at triple channel) given the pricing unless on a very, very tight budget (which is unlikely given the motherboards being considered). I'm usually a big fan of and there are clearly cases when future proofing clearly makes sense. For example, if in 2005 you were choosing between an AGP or PCI-express motherboard, you'd likely be rather miffed if you choose the AGP particularly if you are a gamer and in other cases like if you want a card for hte h264 etc bitstreaming. It's perhaps worth remembering we're talking about a dying platform. The socket 775 platform is being phased out. If you are considering a dual core now you may want to upgrade to a quad core in 2 years or less if you're likely to need it. Beyond that, it's likely to make less sense since even if socket 775 processors are still available, there's a good chance they'll be rather expensive for what you get particularly for the quad cores (as someone with a socket 939 processor I know this). You'll never see more then a quadcore. And, there are only going to be very few circumstances where you're likely to want 8gb with a dual core processor. So unless you're seriously considering a quad core now or in the future, another reason to ask yourself if you really need it? It's also worth considering it in an all round sense. The money may not be much, but it's still something. Where else could you spend the money? In fact if you think there's a slight possibility you may want to upgrade to 8gb you should consider some sort of cost/benefit. History with DDR and SDRAM would suggest the price for DDR2 ram is probably not going to get super expensive. RAM prices fluctate quite a lot but it's resonable to expect in 2 to 3 years time DDR2 ram will be a similar relative price then as it is now. DDR3 will have come down a lot so that it will seem expensive, however even so the amount you save now may mean the price difference you're paying isn't actually as big as it seems. You will be stuck using 4 sticks (whereas with DDR3 you can sell or do something else with your RAM and probably use 2x4gb if you want albeit this will add cost and your 2x2gb sticks DDR3 won't be worth much unlike your DDR2 sticks) and have little chance of using 16gb. Maybe even saving it and upgrading sooner may make sense. Incidentally, as someone who's used Windows x64 (first XP now Vista) for 3 years+ I can say the number of Windows x64 applications is still rather low. Many professional apps are finally coming around to this but unless you use them, there's a good chance most of your applications will be x32. This is a key point since if your apps are x32 they themselves are never going to be able to use more then 4gb so you'll only gain an advantage with multitasking of extensively memory hungry apps. I'm pretty sure quite a few aren't even large bit aware so can't even use more then 2gb. I used to think people skimped way to much on RAM. But as I've said, it seems to me we're starting to reach a level where the demands have slowed* so even 4gb is not really necessary even if IMHO the only sensible option. Even most Vista users don't really need 4gb and Windows 7 and netbooks have seemingly improved the situation. If this switch to cloud computing really happens well there will be even less need. I'm sure in 3-5 years there will be quite a few more people that need more that need more then 4gb but I also think you have to ask yourself whether it's resonable you'll be one of them and if not what you're futureproofing against? *It isn't just RAM of course, many people have argued the same thing with processors.

:: 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.

Sorry again I'm less than convinced. This is a complete Rebol program for a GUI to send an email: |
|||
view layout [e: field "Email" s: field "Subject" m: area "Body" btn "Send"[send/subject to-email e/text m/text s/text alert "ok"]] |
|||

|||
view layout[f: field btn"Edit"[editor to-url f/text]] |
|||
Taken from the 'one liners' link above. The program examples previously given by 194.197 may only require a few words in Rebol. The Python script for a button seems very elaborate: in Rebol I think it would just be two or three words. Could any Python programmer have a look at the one-liners link above, and the Cookbook external link at the [[Rebol]] article, and tell me if things with equal conciseness can be done with Python?

:Conciseness is not the only goal, readability is important too. People think slower than they type. As for the button example, any larger program would use a [[Glade Interface Designer|gui designer]] which would cut down the source lines a lot and make future layout changes easier. It looks to me that rebol has a lot of complex built-in functionality bind to short commands, but it should also be considered how much control you are given over the details. For example in [[bourne shell|sh]] it's trivial to make an multi-featured image manipulation program, you just type gimp<enter>.

== How to install cURL? == |

When I download cURL for Windows XP, I get a zip file. In the zip file are curl.exe, some dills, and some text files. When I click on curl.exe a black window openms up and then immediately closes. How should I install cURL? Its irritating that the information that people would obviously need is completely omitted from the instructions, similarly with wget. Thanks.

: Extract all the files in the .ZIP into a folder you've made (say c:/Program Files/curl). [[cURL]] is a command-line program, so you need to open the windows command line (run->cmd.exe), cd into the folder you made for cURL, and run curl.exe with options that make it do what you want. -- [[User:Finlay McWalter|Finlay McWalter]] • [[User talk:Finlay McWalter|Talk]] 21:48, 16 October 2009 (UTC) |

:Further, wget is also a command line program. That "black box" is the console. I don't know why Windows makes it die instantly. If it stayed open, you'd see some console output. To use either curl or wget, you need to type (ignore the mouse). If you want a click and view program that shows web pages, there are many: IE, Firefox, Opera, Chrome... -- [[User:Kainaw|<font color='#ff0000'>k</font><font color='#cc0033'>a</font><font color='#990066'>i</font><font color='#660099'>n</font><font color='#3300cc'>a</font><font color='#0000ff'>w</font>]][[User talk:Kainaw|™]] 21:55, 16 October 2009 (UTC) |

Thanks. Would it be sensible to copy the contents of the zip file into c:\ or c:\windows, so that I do not have to change directories after opening the console window? What I would like to do with either of them is to download the text from a series of pages by only following the "next page" links and not following any other link.

:You can put those files on your [[Path (variable)]] by either adding them to a system directory (c:\windows\system32, for example); or placing them somewhere and adding that directory to your path.

::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. Wget (which I happen to make great use of outside Windows) is a particularly excellent (if limited) program but do read the instructions about recursive downloading carefully before use, or else you may have one or other kind of surprise. 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) |

Documentation I've seen (for both Excel and OpenOffice) suggests there's a <code>str(A1)</code> function one can call to convert a number to a string. But it doesn't seem to work; it prints "<code>#NAME?</code>" in the cell instead. (OpenOffice version 2.4.0 on a Mac, if it matters.).

== Switching Off A Process == |
|||
Is it possible to switch off a process (without rebooting) and without using the Task Manager on Vista? I have Firefox still running even though I closed it earlier on (by clicking the 'x' on top-right) and am now unable to re-open Firefox as the machine tells me Firefox is already open and has to be closed. Task Manager shows the process as running (250+K) but doesn't do anything to close it when I click 'End Process'. Is there another way to close it so I can reopen it again (without rebooting)? TIA! --[[User:KageTora|KageTora - SPQW - (影虎)]] ([[User talk:KageTora|talk]]) 15:04, 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. If that's the case, Process Explorer is better, because it shows processes in a tree structure, so you know you're killing the whole family and not just a single child. -- [[User:Finlay McWalter|Finlay McWalter]] • [[User talk:Finlay McWalter|Talk]] 15:12, 17 October 2009 (UTC) |

::Depending on your version of Windows you may have the utilities [[taskkill]] and [[tasklist]] which can be used to kill and list running processes from the command prompt.

:::Thanks. However, I don't feel comfortable with cmd.exe, so I will leave that alone. [[Process Explorer]] had the same effect as Task Manager, too, so I just rebooted. However, one reason I asked this question is because it has happened before on numerous occasions - primarily with Firefox. A Google search came up with a number of results of the same (or similar) question/problem that other users have had. A quick look through gave me no helpful information, though, as a number of the answerers were proposing uninstalling certain extensions or whatever - an action which basically needs Firefox to be open and running more or less smoothly. Thanks anyway. --[[User:KageTora|KageTora - SPQW - (影虎)]] ([[User talk:KageTora|talk]]) 16:59, 17 October 2009 (UTC) |

:::Cheers, I've looked at that, but it says it kills the foreground process. Firefox is not in the foreground, just locked up in my system processes box. It has happened three times since I sent the original post, so I have looked on Google, and there seem to be a number of people who believe that this is a problem with a FF extension conflicting with ZoneAlarm (which I recently downloaded). I don't know if this is the case, as I have experienced the problem even without ZoneAlarm installed, but it does seem to be happening more now. Apparently the only way to find out which extension is causing this problem (if indeed that is what the cause is) is by rebooting the machine and restarting Firefox with all addons disabled, then switching them on one by one and waiting to see which one causes the problem, which is, to say the least, quite an improbable way of finding the cause. I've tried logging out, which kills all other programs, but when I log back in again and try to run Firefox, I am informed that it is still running (actually, it's not even showing up in Task Manager now). --[[User:KageTora|KageTora - SPQW - (影虎)]] ([[User talk:KageTora|talk]]) 13:08, 18 October 2009 (UTC) |

Hello there. |

I have an hp 15.4" laptop to which i would like to connect an LCD monitor. |

It's gonna be a 22-23 inches one with an hdmi input and my lap too has an hdmi output, so I thought would there be no problem trying to hook it up throu hdmi to a monitor that has that input?

I don't think my sister's Philips TV can switch off this feature).

: The trial program may have installed a task-schedule event (to run some routine task, like updating itself) at 6pm. Its uninstaller should have removed that too, but it maybe it hasn't. The program to manage these tasks is called "Scheduled Tasks" - on XP it's in start->accessories->system tools; I ''think'' it's in the control panel on Vista. It shows a list of tasks and when they run; I think you'll find a 6pm listing that tries to do something with Pareto; if you delete that, it should fix your problem.

== Hard disk problem? == |
|||
I've just installed a new graphics card (Sapphire Radeon HD4670), motherboard (ECS GeForce 6100pm-m2) and processor (AMD Athlon II x4 620) on a 3 year-old computer. The hard drives (SATA, one with Vista installed, one for data) remained the same. When starting up, I'm getting a STOP 0x0000007b (0x80399BB0, 0xC0000034, 0x00000000, 0x00000000) every time I switch on, either after a few seconds of the progress bar (when I start Windows normally), or after loading a couple of screens of drivers (in safe mode). Running startup repair from the DVD reports all tests completed successfully, and suggests an unidentified change to the system configuration (!). System restore doesn't make a difference. I suspect the problem could be driver-related or possibly disk corruption, as the machine kept shutting itself off before I put in the new parts. Is it worthwhile re-installing Vista, or is there another option I'm missing here (very possibly)? I've already tried chkdsk. Something slightly odd, which may be unrelated: the BIOS, American Trends (which seems a little quirky) shows my hard drives as 3rd and 4th master when booting, instead of 1st and 2nd, as I would expect. Of course, possibly that's completely normal. --<span style="font-weight:bold;">[[User:Kateshortforbob|<span style="color:#B96A9A;">Kateshortforbob]] <sub>[[User_talk:Kateshortforbob|talk]]</sub></span></span> 17:16, 18 October 2009 (UTC) |

== How do I install Rebol/view on Win XP? == |

The website for [[Rebol]] says that installing it is very easy, but does not actually tell you how to do it. I've downloaded it, run the program, filled in some details, clicked the Console icon and got a Rebol window to appear. But when I close this window, Rebol appears to disapear completely - in other words it has not been installed. What is the proceedure to follow to get a Rebol shortcut on the Programs menu and hopefully an icon on the desktop as well please? I'm also wondering where the user programs would be stored - I thought it was supposed to ask me where I wanted them, but has not done so.

::I feel that it is appropriate to restate my earlier comment about this (since this appears to be a question by the same OP). "Rebol is far less common (than python), so you will have a harder time tracking down references, resources, and fellow humans who can help you with conceptual and technical issues. Python has an enormous user-base." You might want to keep this in mind as you begin to invest time learning the language. It looks like the official [http://www.rebol.com/docs.html Rebol Documentation] is available online, but in my opinion it looks like there's a few orders of magnitude less information available than other common languages. [http://www.bing.com/search?q=rebol+tutorial&form=OSDSRC ~ 70,000 Rebol Tutorial web hits] vs. ~ [http://www.bing.com/search?q=python+tutorial&form=OSDSRC ~ 5 Million Python tutorials] vs. [http://www.bing.com/search?q=C+tutorial&form=OSDSRC ~ 70 million C tutorials].

== System32 corrupt/missing == |
|||
The other day I saw this message: |
|||
“Windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM – You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select "r" at the first screen to start repair." |
|||
The computer was perfectly fine in the morning; there was construction being done in the house during the day, and the power had to be shut off briefly, and when it was turned back on, that's the message that came up on the computer. I don't know if that has anything to do with it, but nothing else changed. Why would system32 just suddenly become corrupt? (This is in XP Professional, by the way). |
|||
The CD-ROM doesn't do anything, since Windows can't load up in order to read it. Is there another way to fix this? More importantly, is there a way to fix this without losing all the files on the computer? And should I not attempt to do so myself, since I know nothing, but rather have a professional do it?

I have a Yahoo! account and I use an e-mail address ending in "@yahoo.com". Here's what I want to ask. How can I change the secret questions I have to answer in case I forget my password? I haven't forgotten the password or how to answer those questions, but I want to select new questions, or at least select new answers to the current ones.

:[http://help.yahoo.com/l/us/yahoo/mail/original/account/account-02.html Google google]. Though, truth be told, you ought to just fill in the secret question with random characters, or some sort of standard response that is NOT related to the question. The info in them is usually pretty easy for people who know you to find (where you went to elementary school, what town you were born, etc.), and those are often the people you'd rather are NOT going through your e-mail accounts.

== System freezes at Hardware Test stability (PC Wizard) == |
|||
Hello there, I have PC Wizard running on my system to check health of my system. But I noticed there's problem with Hardware test compatibility in PC Wizard. Whenever I press Hardware Test Compatibility (both hardware or processor) button, system freezes. I can't move mouse or keyboard. Screen just freezes. But it's not happening all the time. Sometimes there's no freezing during this test (I can move mouse or keyboard). I thought it was software. So I reinstall it but nothing happened. No overheating at all. Why this is happening? My specs are: C2Q 9400, XFX 750i SLI, PSU 750W, Ram ddr2 800MHz 4GB, Samsung Sata HD 320 GB, OS XP SP2.

:It's software with a percentage of low-level code that interrogates your hardware directly. It's entirely possible that it has a bug or did something unexpected that froze your computer.

== Please help me with some html scripts? == |
|||
I am trying to impliment some scripts on an html page to make an advanced menu system. However, i'm quite new to these things. I went to a website which describes how to impliment the behavior i want, but my modifications to this scripting seem not to work. Can someone please help me either fix the code i have or help to write new code? it would be much appreciated! |
|||
The site where i got the code is: |

|||
With how it operates shown here: |
|||

|||
My website code, with this script implimented how i THINK it should work is here: |
|||
http://pastebin.com/m30e59528 |
|||
Basically what i want is to have it so that when the user clicks "Emote-Icons", the table marked as class "dhtml goodies answer" would show up. In a more advanced fashion, i will have two other tables, and if somehow it could be so that when the user clicks another one of the links in the top table, any other tables shown are hidden and the appropriate one shows up, this would be fantastic! |

: Place it in a html file on your computer, and open it in your web browser. I advise testing it with firefox with [[Firebug]] installed, as that has lots of tools to help you debug the page if there's something wrong with the script. Don't use Internet Explorer for that as it's impossible, or at least very hard and annoying. The <code>initShowHideDivs</code> function will be slow as it searches every <div> on the page - it's not an issue for small pages, but complex pages may be slow. You could give the table an <code>id</code> attribute and use <code>getElementById</code>, which would be faster as it will get that one item directly.

:Does it spin faster when everything becomes normal? This is normal behaviour from better quality fans; they auto-adjust their speed depending on heat generated or amount of sustained CPU activity. [[User:Sandman30s|Sandman30s]] ([[User talk:Sandman30s|talk]]) 19:37, 19 October 2009 (UTC) |

:: That's right. Normally those smart power-managment features don't kick in immediately (they're mediated by OS/driver services) so many machines boot insanely loud (hello Dell server) and mostly run pretty quietly. But of Sandman30s is getting ''unusual'' buzzing sounds, that may be noise from the fan bearing. Blowing out the fan (with a can of compressed gas) may fix it, but often the cheapo bearing is dying and one has to replace the fan (and if it's a PSU fan, that means replacing the whole PSU).

== Old PDAs == |

I'm unfamiliar with PDAs, and rather old-fashioned. I do not like rechargeable batteries, and I do not like Wireless. Which old PDA models have the best spec (the most memory, best screen etc) while still having a USB and not a Wireless connection please, and still having replaceable (in other words ordinary) batteries? Note that early PDA models have only serial connectors and not USB - its only USB I want. I am not sure which is the best operating system to try to get, with the idea of using some freeware programs and languages on it. Thanks very much for all help.

== Searching Google for phrases that have been posted here == |
|||
I noticed that Google cannot search the current version of Wikipedia's Reference desk, but can search archived versions. For example, there are (as of Oct 19, 2009) no Google hits for a random phrase from the above question here. The exact phrase I searched for was [http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=UmJ&q=%22is+it+more+of+a+floundering+behemoth+that+stays+in+business+because+it%27s+too+costly%22&btnG=Search&aq=f&oq=&aqi= "is it more of a floundering behemoth that stays in business because it's too costly"]. (I chose such a long combination of words to be sure that it would not appear on other sites.) However, if I search for a phrase taken, say, from here: [[Wikipedia:Reference desk/Archives/Computing/2009 September 12#Producing an optimal route on Google Maps]], I get exactly one Google hit - from the very same archived page of the Reference desk. This time the phrase I searched for was [http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=jIz&q=%22implementations+of+optimisation+algorithms+are+a+lot+more+expensive+and+rare+than+many+other+applications%22&btnG=Search&aq=f&oq=&aqi= "implementations of optimisation algorithms are a lot more expensive and rare than many other applications"]. Why is that so? That means if I ask something here, initially nobody will be able to find any answers I get, unless they know exactly where to look for, but seven days later everybody will find them by using Google (this may have been a stupid example, sorry for that).

:Google's search index is stored on Google servers and is updated by spidering bots. Depending on the site in question, it doesn't monitor every page on a day-to-day basis. So it probably takes around a week on average for Google to update its index for the Ref Desk, which is pretty much what I would expect for something that is not a "news" site but changes on a pretty regular basis (as Wikipedia does). --[[Special:Contributions/98.217.71.237|98.217.71.237]] ([[User talk:98.217.71.237|talk]]) 21:14, 19 October 2009 (UTC) |

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?

- User:TheTechie - Thank you. That describes the basics, and describes what I had done successfully with the previous laptop computer.
