I was just wondering if it is possible to connect to a chrooted environment with VNC... forgive me if this is nonsense, I don't know much about this stuff... it's just that I'm having lots and lots of problems trying to use graphical applications inside a chrooted environment... (yeah, I know how to use the terminal, but it is not enough...) SF007 (talk) 03:40, 24 August 2008 (UTC)[reply]

X11 by TCP can be used in this situation. Setting DISPLAY=127.0.0.1:0 in the environment probably should be enough to use it. By default, X uses a Unix domain socket which requires a file which is probably not included in the chroot. MTM (talk) 08:27, 24 August 2008 (UTC)[reply]

when an autorun doesn't function and it gives the message 'the application failed to initialize properly (0-c0000006) click on OK to terminate the application', how can it be resolved? Some file is missing? How can I know which file? Thanks. --Omidinist (talk) 07:58, 24 August 2008 (UTC)[reply]

Is there _any_ way to input a regular expression and find all possible strings that it would match? Processing time, memory, and storage are of no concern. I don't care how wacky or out of the way the solution is. If I have to install a virtual machine running Plan 9 on a 64-bit edition of Windows 7 I'm for it. This is only for simple regular expressions, like (T|t)itles? --mboverload@ 08:06, 24 August 2008 (UTC)[reply]

In most cases, there is no upper bound on the length of a string that can be matched, so there is an infinite collection of matching strings. How do you suppose they can all be listed? --tcsetattr (talk / contribs) 08:36, 24 August 2008 (UTC)[reply]

Sorry, I should have clarified this is only for simple regular expressions, like (T|t)itles? --mboverload@ 08:49, 24 August 2008 (UTC)[reply]

But /.*/ is also simple and there are simply infinite number of matches. You have to refine your definition of "simple" a bit before this can go anywhere. --antilived^{T | C | G} 09:07, 24 August 2008 (UTC)[reply]

It is possible with regular expressions like /x|y/, /x?/ or /x{1,3}/ and their combinations. Just all possibilities have to be enumerated and collected in a set. I haven't heard about any program which does it, but it looks simple. MTM (talk) 09:29, 24 August 2008 (UTC)[reply]

Here's a subset of the list matching the regular expression "(T|t)itles":

Titles
titles
abcTitlesxyz
!"#$Titles%&'()

See where this is going? Without anchors ("^" at the beginning and "$" at the end) you haven't limited the length of the string that can be matched. A regular expression that matches only a finite set of strings would have anchors at the beginning and end, and no "*" or "{N,}" quantifiers. It's pretty easy for the finite lists to be very large too. "^[a-z]{5}$", matching any string made of 5 lower-case letters, has 26^5=11,881,376 possible matches.

I though only about the matched part, so /a/ would result only in "a". From the original post: "Processing time, memory, and storage are of no concern.". MTM (talk) 09:37, 24 August 2008 (UTC)[reply]

If you're thinking that this regexp-to-list converter would be a good tool for learning regular expressions, I hope you've changed your mind by now. (There are tools for that already; search for "regular expression editor" or "regular expression debugger".) --tcsetattr (talk / contribs) 09:33, 24 August 2008 (UTC)[reply]

I don't know as much about regular expressions as you, but I hope you look at the spirit of my question. (T|t)itles? , in my mind but not the computer's, has 4 possible matches, Title, Titles, title, titles. I'm not trying to generate a list of every valid Visa number =). I don't know how to format it correctly so it wouldn't match things outside of the word, but that is something I will learn. Thanks for your expertise. --mboverload@ 09:40, 24 August 2008 (UTC)[reply]

The deeper point in my reply was that regular expressions in real usage are quite often not anchored at both ends. We grep for patterns in a file, but we want to see the whole line that contained the match, not just the matched substring. And the "*" repetition operator is used a lot. The proposed listing tool will apply only to a small minority of useful regular expressions. As an educational device it would suck. For generating lists of strings with alternatives like /[Tt]itles?/ -> {"Titles", titles", "Title", "title"} and /[a-z]{5}/ -> {"aaaaa", "aaaab", ..., "zzzzz"} you don't really need a regular expression. I'm left wondering if there's another motivation. Because if it's a good idea, this tool wouldn't be hard to build. --tcsetattr (talk / contribs) 09:56, 24 August 2008 (UTC)[reply]

Well, if time is LITERALLY of no concern then (in a Linux/Cygwin setup) you could write a 1 line C program ('while(1)putchar(rand()%127);') that would generate random strings and pipe the result into 'grep'. That exactly fulfills the demands of your question...so consider it answered!

But for a practical answer (which is what everyone else is attempting to provide), because so many regexps can match a literally infinite number of strings you have to sharply limit the regexp syntax to (for example) prohibit '*' or anything that matches a variable number of characters. So this tool you imagine wouldn't be able to operate on "normal" regexp's - only within this rather carefully restricted subset. But even so, in almost all "real" examples of regexp's the combinatorial explosion will kill you. So it becomes just really unlikely that anyone will try to write such a tool in a 'normal' manner. I think you're doomed!

SteveBaker (talk) 16:52, 24 August 2008 (UTC)[reply]

Enough philosophy, here's an implementation. This is a Haskell program that takes a regular expression on the command line and prints out all strings matching that regular expression, without duplication, sorted by length and lexicographically within each length. It supports only "theorists' regular expressions" and not Unixy extensions like [a-z] or a{3,5} or even . (though it does support ? and +). If the regular expression matches infinitely many strings then the program will run forever but every matching string will be printed at a finite time. I tested it with GHC but it should work with Hugs or any other implementation that supports the Parsec library. If you save the program as regex.hs you can compile it with the command line ghc -package parsec -O -o regex regex.hs. It's quite fast (not that it couldn't be faster) and I find the output from expressions like (aa|bbb)* rather soothing. I hereby release this code into the public domain. Let me know here or on my talk page if you notice any bugs.

Hi; there's a user uploading episodes of a television program to YouTube, and putting the names of other programmes in the tags. This means that whenever searching for any of the listed programmes, one has to wade through pages of the irrelevant episodes he produces before getting to what one wants. I made two polite comments about this; the first received a polite but negative reply, the second just resulted in the whole conversation being wiped and my commenting privileges being suspended. I've emailed this user, but don't expect this to prevail.

The question is - what next? Is there a "report to staff" option where I can make clear what it is I have a problem with? A "report user" facility? A way to exclude his videos from my search results (failing ways to help the whole community by clearing them, that is!)... any tips?

I have a few questions about installing programs on Ubuntu. Thus far I have been installing through the repositories.(With the various methods possible,"sudo apt-get install" along with "Add/Remove" in the Main Menu). But what about stuff that's not in the repositories and needs to be downloaded? For that stuff I encounter files that might end in "tar.gz" or something and when the message pops up it says Bzip archive. It says Archive Manager is the default thing for this sort of thing. So I select it, extract and all that. And then....nothing. Is the program installed? How do I run it? Are there other ways of getting programs? Did I do something wrong? And what's installing through source? Sorry for all the questions. Thanks in advance.--Xp54321 ^{(Hello! • Contribs)} 15:25, 24 August 2008 (UTC)[reply]

There's usually a file called "README" or "INSTALL" to look at, but the normal procedure is to open a shell, cd into the directory, and run:

./configure -- you don't always need to run this, sometimes it is missing

make -- this compiles it all and creates the program for you to run. The program is normally placed into the "bin" directory.

It is normally best to run it from the bin directory, but some projects can be installed into /usr/bin etc with: sudo make install

That's the basics - it might fail if you're missing some libraries. If so, try and work out what they are and install them with synaptic. --h2g2bob (talk) 16:22, 24 August 2008 (UTC)[reply]

Thanks for the answers, but what does "cd into the directory" mean? How do you open a shell?--Xp54321 ^{(Hello! • Contribs)} 18:14, 24 August 2008 (UTC)[reply]

A "shell" is a program that presents a command line interface to the computer's file system, programs and processes. It's mostly just a way of making system calls, running programs etc, but it will also feature commands that work together to form a quasi-programming language allowing you to write little scripts which use logic, control flow, interaction between programs etc etc. Anyway, to open a shell, choose Main Menu >> Accessories >> Terminal. "cd to a directory" means use the "cd" command to change the working directory of the shell to a certain directory. Here's an example from my shell

me@mycomputer:~$ ls
Desktop  film  incoming  music  oddments  print  sort  tools  zoo
me@mycomputer:~$ cd oddments/
me@mycomputer:~/oddments$ ls
bills  flat  megadrive  sainsburys
me@mycomputer:~/oddments$ 

The "ls" command lists directory contents. Note that "~" is an alias for your home directory (/home/me). You can type "help" at the prompt to get help about built in commands, or use man to get help about specific programs. Also, building from source means getting a compiler and associated tools on your very own computer to create an executable program from the source code supplied. It's kinda fun, and reassuring to do once in a while to prove you can. —Preceding unsigned comment added by 78.86.164.115 (talk) 18:59, 24 August 2008 (UTC)[reply]

cd means to change directory and shell is the terminal (Applications>Accessories>Terminal).

Well, I'm not really an expert or anything, but basically, you can have an FTP site as well. It's essentially like, oh, the folders on your computer, where you can see and copy and move the files or folders on your hard drive. Only it's for files on a server. Archives of files (like the Interactive Fiction Archive, for example) often have an "FTP mode", because some people prefer to view files that way instead of in a big list. --Alinnisawest(talk) 18:53, 24 August 2008 (UTC)[reply]

FTP is faster than HTTP, because there's less overhead. As for a site, I don't know about Apache, but I've set up FTP sites using the IIS feature built into Windows XP and Server 2003.

On Unix-like systems proftpd or vsftpd can be used. Since FTP is less secure (does not support encryption of e.g. passwords used for authentication) I use sftp instead. MTM (talk) 19:52, 24 August 2008 (UTC)[reply]

HTTP is a newcomer among Internet protocols. FTP is one of the oldest Internet protocols still in use. Many of the online file archives that are now offered through HTTP began as FTP archives (and are still offered that way). Accessing archives through FTP has some big advantages over HTTP, like the fact that FTP clients let you transfer whole groups of files using wildcards or drag-and-drop. However, FTP is a pretty bad design; it survives only by virtue of its entrenchment. It certainly isn't faster than HTTP (unless your HTTP implementation is broken) and in many cases it will be slower. Also, it doesn't work well through firewalls or through tunnels (like SSH tunnels). Despite its similar name, SFTP is a totally different protocol. It's a much better design which combines the advantages of FTP and HTTP for file transfer. Unfortunately the software support for it isn't nearly as good as for HTTP or FTP, at either the client or the server end. -- BenRG (talk) 20:21, 24 August 2008 (UTC)[reply]

Actually from what I've read, FTP is "certainly" much faster than HTTP.--129.82.41.232 (talk) 21:18, 24 August 2008 (UTC)[reply]

Those huge paperback training tomes that litter the "Computers" section of bookstores are, to put it politely, not written by experts. Only the third book you linked offers any reason for its claim, and surely you can see that the reason ("because FTP does not support the display of graphics or streaming media, it can transfer files much faster than HTTP") doesn't make any sense. (The same book goes right on to claim that FTP can't be used to serve web pages, which must be news to these people.) Both HTTP and FTP just send the raw bytes of the file over a TCP connection. HTTP supports sending more than one file over a single TCP connection, FTP doesn't. If FTP is faster it's because HTTP is being routed through a slow proxy, or the ISP is throttling HTTP connections, or something else that has nothing to do with the protocols as such. -- BenRG (talk) 00:14, 25 August 2008 (UTC)[reply]

I formatted and reinstalled Windows XP on one partition of my HDD and now my GRUB bootloader menu won't show up to let me boot Linux. What do I need to do to get the menu back? (By the way, I chose only to format the partition that Windows was on by using the OEM's CD). Ζρς ι'β' ^¡hábleme! 20:19, 24 August 2008 (UTC)[reply]

It rather depends what that OEM CD has done. Some are proper windows installers, in which case the installer has zapped the disk's master boot record. If that's the case, boot with a liveCD and restore grub (see the grub documentation). If, as is common with many OEM restore disks, it's not a windows installer but a Norton Ghost-like disk image extractor, then it has zapped your linux partition and you'll need to start again. You can tell which has happened by examining the partition table for the disk (either using Windows' disk manager plugin or Linux's gparted). It's incumbent on me at this point to repeat my oft-ignored plea to those trying Linux for the first time - "Repartitioning and bootloaders are hard for those with limited, windows-only, experience. Cheap removable IDE disks (one for linux, one for windows) is the path of least pain for the unwary".

There are tools for doing this (wget can certainly copy pages recursively (see article on wget), but I'm not sure whether it rewrites all the links to point to local copies), but there is a (slight) caveat: websites and their administrators HATE this sort-of behaviour. Depending on how much you download, this can put an enormous strain on a server. If you want a good list of these sorts of programs, you can look at what programs wikipedia bans in its robots.txt: [1] (look at the note on wget, for instance). If you do this, please act responsibly, and not completely crash the server you're downloading from. 90.235.4.253 (talk) 21:56, 24 August 2008 (UTC)[reply]

If you're only downloading one copy of things it's usually not that bad. Wget only really runs into trouble if you're flooding the server with requests (rather than just one at a time) or if you instruct it to download massive amounts of giant file sizes (e.g. videos and etc.). But just mirroring sites is usually not any more server strain than browsing usually is. --98.217.8.46 (talk) 02:00, 25 August 2008 (UTC)[reply]

The -k or --convert-links option to wget should alter the links to allow local viewing. -- Coneslayer (talk) 17:03, 25 August 2008 (UTC)[reply]

Using a Windows machine? Try HTTrack. It's easy to use, and robust. There are also Firefox extensions that can do this; I've used one called ScrapBook to good effect, except that it doesn't maintain releative paths (e.g. all the HTML gets dumped into one big directory with all the images, etc., which is fine if you are just saving the page to view it later—it'll all work just fine in Firefox—but not so good if you're doing web development with it and need it to be a perfect mirroring of the file structure, not just the appearance). --98.217.8.46 (talk) 02:00, 25 August 2008 (UTC)[reply]

Thanks for the answers so far. And yes, it is a Windows machine. StuRat (talk) 19:30, 26 August 2008 (UTC)[reply]

Can you tell me the websites that are about crucifixions?24.165.11.18 (talk) 22:00, 24 August 2008 (UTC)[reply]

You can search the Internet for this information using a search engine like Google or Yahoo!. Go to google.com, type "crucifixions" into the box, and click "google search". You'll then get a list of the websites related to crucifixions. --h2g2bob (talk) 23:41, 24 August 2008 (UTC)[reply]

As I wrote on August 23, whenever I get a page or email listing a phone number, it simply vanishes from the screen. Like, if someone sends me an email with their telephone number, it will briefly show up and then fade away. Also if I look up a phone number on White Pages.com the same thing happens. I also will be on a site looking up (say for instance the nearest Walgreens) Walgreens.com will show the store address and phone number and before I can write it down it fades away. This is very puzzling to me. I don't recall this happening in the past....just the past couple of months. I haven't been doing anything different with my computer lately. Does anyone else have this problem64.184.124.178 (talk) 23:20, 24 August 2008 (UTC)[reply]

It's only phone numbers that disappear? Does it just leave a white space where it was? Ζρς ι'β' ^¡hábleme! 23:45, 24 August 2008 (UTC)[reply]

Perhaps it's a screensaver coming on (or backlighting on a backlit screen going off). Moving the mouse will bring it back if this is the case. --h2g2bob (talk) 00:39, 25 August 2008 (UTC)[reply]

Please don't repost the same question each day. You will continue to get answers where you originally posted: [2]. StuRat (talk) 00:57, 25 August 2008 (UTC)[reply]
