• WMII Terminal Width of 80 Columns for xterm (colrules)

  - by BCable

  I'm trying to get WMII to split horizontally at 80 columns for xterm, but I'm only seeing a way to do this via percentage. It would be nice to be able to set it by something other than percentage for various resolutions, but if I have to deal with that I will. The problem is that even percentages don't work at my resolution (1366x768). 47+47 in /colrules yields 79 characters and 48+48 yields 81 characters. As far as I can tell, there is no decimal system allowed so I could do 47.5 for instance. I came from Ion3 and I'm used to using 80 column terminals, resizable by the keyboard, to get a reasonable cut off point for VIM when I'm coding. I would just settle with using the mouse, but WMII seems to be much more fluid than Ion3, so I would have to do it a LOT, which sounds annoying. Any ideas?

• Using slime's C-x C-e (Eval the form under the point) with swank-clojure in emacs

  - by hiheelhottie

  Hi, I'm using swank-clojure in emacs on OSX. I'm able to run a slime session. When I use C-x C-e on a simple form in a .clj file like (+ 7 7) I get an sldb buffer with Unable to resolve symbol: + in this context [Thrown class java.lang.Exception] I'm able to evaluate that form in the slime session directly. I was hoping the form in the clj file would get evaluated in the running slime session. Can someone explain how C-x C-e works in swank-clojure and how I can get the form to be evaluated in the running slime session? Thanks, hhh

• How to use windows desktop from a linux machine in a local network?

  - by Hristo Hristov

  I have a computer running Windows 7 with no monitor or keyboard, connected to a local network. I have a few laptops running linux, also connected to the local network. I want to feel like I'm sitting in front of the windows, but using one of the linux laptops. How to do that? Maybe I can use some linux software to connect to remote desktop? Or I have to install client/server software on both machines? As this is a local network, I expect excellent experience with no lag. Thank you!

• C++ code beautifier for emacs/linux

  - by aaa

  hi I am looking for code beautifier for UNIX/emacs. I have looked at gnu indent, artistic style, however I need something a bit different. For example, I would like the following: for( int x= 0;; ++ x) if(x) break; to be formatted as for (int x = 0; ; ++x) if (x) break;. As far as I can tell artistic style does not do that (correct me if I am wrong). What can you recommend? Thanks edit both, artistic style and indent remove whitespace. Here is a small interactive command to beautify region: 405 (defun my-emacs-command-beautify-region() 406 (interactive) 407 (let ((cmd "astyle")) 408 (shell-command-on-region (region-beginning) (region-end) cmd (current-buffer) t))

• Ubuntu server hangs on reboot "could not stat resume device file"

  - by matnagel

  Instead of booting into the running system this machine stops and on the terminal I can see a message: could not stat resume device file /dev/sdb5 When I attach a keyboard and press enter the boot continues and the machine comes up like normal. But it's essential that this machine comes up under most circumstancs alone. There never was something like a "resume" on this machine. I tried several times to reboot, but this does not happen on all boots, I can not find a pattern here. There is a software raid running on the box. This is the syslog during boot: http://privatepaste.com/ff0fd0a51c/sdabfjahfgasjkgfu4gfsdzjcgfafasdjfhgasdcjfgauzfgafasgdufzg How can I get rid of this boot failure? We do not need resumes and best would be something that works here and now.

• jQuery Audio Player

  - by tony noriega

  I was given 2 MP3 files, one that is 4.5Mb and one that is 5.6Mb. I was instructed to have them play on a website i am managing. I have found a nice, clean looking CSS based jQuery audio player. My question is, is this the right solution for files that big? I am not sure if the player preloads the file, or streams it ? (if that is the correct terminology) i dont deal much with audio players and such... this player is from happyworm.com/jquery/jplayer/latest/demo-01.htm is there another approach i shoudl take to get this to play properly? I dont want it to have to buffer, and the visitor to wait, or slow page loading...etc..etc.. i want it to play clean and not affect the visitors session to the site. thanks

• Can a client determine whether the server has accept()'d a unix socket?

  - by Havoc P

  I'm dealing with a buggy server that will sometimes fail to accept() connections (but leaves its listening socket open). This is on Linux with unix domain sockets. Currently the only way to detect this is that after sending a bunch of data, the buffer fills up and blocks, and the server isn't sending any replies. This long-after-the-fact failure mode is hard to distinguish from other bugs - the server could be unresponsive for other reasons. Especially for unix domain sockets it seems the kernel should know whether accept() has occurred; is there any way to find this out? Can the client block until accept() happens somehow, or at least check whether it has? This is just for debugging purposes so it can be a little ugly.

• Why do my proxy settings keep changing?

  - by tjrobinson

  I am running Windows 7 and a few times a day the "Use a proxy server for your LAN (These settings will not apply to dial-up of VPN connections)." under "Local Area Network (LAN) Settings" checkbox becomes checked seemingly on it's own. Am I pressing some kind of hidden keyboard shortcut accidentally? What sort of applications might alter this setting and why? Unfortunately as this is a developer box, there's a lot of stuff that could be interfering, e.g. Visual Studio 2010, Windows Azure SDK and various browsers. Has anyone else come across this?

• How do I read input character-by-character in Java?

  - by Jergason

  I am used to the c-style getchar(), but it seems like there is nothing comparable for java. I am building a lexical analyzer, and I need to read in the input character by character. I know I can use the scanner to scan in a token or line and parse through the token char-by-char, but that seems unwieldy for strings spanning multiple lines. Is there a way to just get the next character from the input buffer in Java, or should I just plug away with the Scanner class? Edit: forgot to say where the input is coming from. The input is a file, not the keyboard.

• Writing my own iostream utility class: Is this a good idea?

  - by Alex

  I have an application that wants to read word by word, delimited by whitespace, from a file. I am using code along these lines: std::istream in; string word; while (in.good()) { in>>word; // Processing, etc. ... } My issue is that the processing on the words themselves is actually rather light. The major time consumer is a set of mySQL queries I run. What I was thinking is writing a buffered class that reads something like a kilobyte from the file, initializes a stringstream as a buffer, and performs extraction from that transparently to avoid a great many IO operations. Thoughts and advice?

• Bootable and remote controllable imaging software?

  - by stefan.at.wpf

  I am looking for an imaging software, that one can boot from CD or usb stick (therefore without installing anything on the system!) and then control by some kind of remote desktop. So something like a combination of Acronis TrueImage's Bootable Media and Windows Remote Desktop. I don't even need to be able to store the backup on a network drive, as an external usb hdd is attached for these purposes. Background: A system that is normally controlled by SSH / command line and therefore has no keyboard/mouse connected that I could use to control Acronis TrueImage.

• Huge area of stuck pixels

  - by pixelady

  A toddler slammed down my laptop screen while an iPod was laying on top of the keyboard. The damage resulted in a massive area of stuck pixels on the laptop screen, approximately 2 inches by 10 inches in area. I've tried running various programs that rapidly flick the pixels in different colors, as well as massaging the screen with heat and also without heat. These are the standard methods I read about for fixing a stuck pixel. But none of the online articles I read said how to fix a huge area of pixels, not just single pixels. What else can I try to get the many pixels unstuck? My computer is no longer under warranty and I don't want to buy a new one.

• Performance problems on RDC to our Terminal-Server Win2008 R2

  - by user40021

  Hello, we have a new win2008-R2 (2x Xeon X5570, 32GB RAM). There I have installed the terminal-server roles, thats all OK. Currently 5 users are working at this server, but all get a very low performance in their remote-desktop session. Sometime it takes 1-2 seconds till the keyboard-inputs will be performed and shown. At the clients I run RDP v 6.1 We have also an older TS-server (based on Win2003 with an Opteron-CPU), there are working about 20 users at the same time. There I do not have the troubles with the inputs at the remote-desktop sessions. Both servers are connected to the same gigabit-switch. Any ideas what could cause the troubles at the Win2008 R2? Many thanks in advance. Regards Chris

• What is a good motherboard for the Intel i7 series processor?

  - by jasondavis

  I am lost on choosing a good miotherboard at a decent price for my Intel i7-930 CPU. I have read bad things about all of them so far. Issues with RAM not working correctly, Windows not loading with USB keyboards plugged in and all kinds of nightmare stories. Here is my needs. - 6g/b SATA 3 - USB 3.0 - Cheaper is better - Support for up to 24gb of RAM, I will start out with only 12gb though - I will use 64bit v. of Windows 7 so the 4gb RAM limit should not be a problem from my OS - Should be able to boot even if I have a USB keyboard plugged in. If you have experience with a motherboard that meets these specs, please do tell about it. I appreciate any help, I am stuck right now on picking a good board.

• nxhtml and geben: debug mode stops responding to keystrokes upon step into html/php mixed line

  - by artistoex

  I'm using the php debugger geben and nxhtml-mode. While debugging, as soon as I step into a mixed line such as <foo><?php bar(); ?></foo> the debugger is no longer accepting any key-strokes. However, the mode line still indicates the debugger's presence (*debugging*'-entry). I guess this due to nxhtml's mode changes, because it's the exact same behavior geben shows after disabling end re-enabling it. Does anybody use nxhtml together with geben and has fixed it? Or is it possible to configure emacs to enable nxhtml conditionaly, such that php-mode is used instead when the buffer was opened by geben?

• Accessing ArrayBuffer from PHP $_POST after xmlHTTPrequest send()

  - by Dan

  I'm following the tuitions on XMLHttpRequest 2 from : https://developer.mozilla.org/en/DOM/XMLHttpRequest/Sending_and_Receiving_Binary_Data and http://www.html5rocks.com/en/tutorials/file/xhr2/#toc-send-arraybuffer They're great tutorials for the client side, and here is a working extract from my script: var imagebuffer = new ArrayBuffer(size); // create the readonly memory buffer var imagedata= new Uint8Array(imagebuffer); // create a view to manipulate data // do some cool stuff with imagedata var exchange=new XMLHttpRequest(); exchange.open("POST",url,true); exchange.send(arraybuffer); So far so good, and I can see from the both client and server control panels that plenty of data is being transferred. Here's my problem: how do I access the ArrayBuffer with PHP at the server? I'm used to the $_POST superglobal wanting parameters passing from a HTML form so it can be accessed as an array but I can't find any reference for how to access this binary array and stick it in my MySQL database.

• clear html webpage?

  - by noname

  i am currently developing a crawler that crawls all links on the web and displays them in the web browser (and saving it of course). but after some hours there will be a huge list displayed on the web browser and i want to only display lets say 1000 links at the same time. then i clear the html and display another 1000 links. this is also good for the RAM or it will eat up all memory. how do i clear the web browser screen? EDIT: i have seen some scripts using some flush buffer functions. has this anything to do with my case?

• [Python] How can I speed up unpickling large objects if I have plenty of RAM?

  - by conradlee

  It's taking me up to an hour to read a 1-gigabyte NetworkX graph data structure using cPickle (its 1-GB when stored on disk as a binary pickle file). Note that the file quickly loads into memory. In other words, if I run: import cPickle as pickle f = open("bigNetworkXGraph.pickle","rb") binary_data = f.read() # This part doesn't take long graph = pickle.loads(binary_data) # This takes ages How can I speed this last operation up? Note that I have tried pickling the data both in using both binary protocols (1 and 2), and it doesn't seem to make much difference which protocol I use. Also note that although I am using the "loads" (meaning "load string") function above, it is loading binary data, not ascii-data. I have 128gb of RAM on the system I'm using, so I'm hoping that somebody will tell me how to increase some read buffer buried in the pickle implementation.

• How to get password prompt from scp when launched remotely via ssh

  - by Zek

  When I ssh to a remote system and execute scp, I do not get a password prompt: # ssh 192.168.1.32 "scp joe\@192.168.1.31:/etc/hosts /tmp" Permission denied, please try again. Permission denied, please try again. Permission denied (publickey,password,keyboard-interactive). If I break it up like this, it works fine: # ssh 192.168.1.32 # scp joe\@192.168.1.31:/etc/hosts /tmp [email protected]'s password: How can I make it prompt me for the password in the first example above? Note: No, I cannot use key-based authentication for this.

• c++ library for endian-aware reading of raw file stream metadata?

  - by Kache4

  I've got raw data streams from image files, like: vector<char> rawData(fileSize); ifstream inFile("image.jpg"); inFile.read(&rawData[0]); I want to parse the headers of different image formats for height and width. Is there a portable library that can can read ints, longs, shorts, etc. from the buffer/stream, converting for endianess as specified? I'd like to be able to do something like: short x = rawData.readLeShort(offset); or long y = rawData.readBeLong(offset) An even better option would be a lightweight & portable image metadata library (without the extra weight of an image manipulation library) that can work on raw image data. I've found that Exif libraries out there don't support png and gif.

• Manipulating the address of a variable to store a smaller type?

  - by Sidnicious

  This is what I get for pampering myself with high-level programming languages. I have a function which writes a 32-bit value to a buffer, and a uint64_t on the stack. Is the following code a sane way to store it? uint64_t size = 0; // ... getBytes((uint32_t*)&size+0x1); I'm assuming that this would be the canonical, safe style: uint64_t size = 0; // ... uint32_t smallSize; getBytes(&smallSize); size = smallSize;

• How to open Firefox's "organize bookmarks" from Vimperator?

  - by Igor Popov

  Before using Vimperator, I used Xmarks for organizing and synchronizing bookmarks between computers. Now I installed Vimperator and I can only bookmark a page from command mode with :bmark. How can I open Organize Bookmarks with Vimperator? Besides disabling Vimperator and choosing it from the menu what else can I do? Before, I had CTRL + SHIFT + b to open the organizer. Now, in Vimperator, this shortcut doesn't work anymore, even after temporarily disabling Vimperator with CTRL + z. EDIT After setting the main menu visible (with :set go+=m thanks to Hamish Downer), I saw the shortcut for opening the organize bookmarks dialog (CTRL + SHIFT + o). I recently switched to Ubuntu Linux and in this version of Firefox some keyboard shortcuts are different then in Windows (including the shortcut for opening organize bookmarks). Sorry for my ignorance.
