  • How do I change the color settings in emacs23 running in a terminal console?

    - by Anonymous
    I use xterm and set its appearance in ~/.Xdefaults: XTerm*background: paleTurquoise XTerm*foreground: black I also use emacs, but set its appearance differently in ~/.emacs: (set-background-color "black") (set-foreground-color "yellow") I usually run emacs within the terminal console with emacs -nw, rather than creating a separate X window. For some reason, this doesn't work properly for emacs23; instead, emacs retains the pale turquoise background of my xterm window. Looking at what's new in emacs23, I noted that: ** When running in a new enough xterm (newer than version 242), Emacs asks xterm what the background color is and it sets up faces accordingly for a dark background if needed (the current default is to consider the background light). So it's a feature, not a bug? Anyway, is there some way that I can I tell emacs23 to ignore the xterm background settings when running in console mode, and use the settings in ~/.emacs instead? I'll also note that: Running M-x set-background-color within emacs23 -nw has no effect. It works fine in emacs23 running in a separate X window (without the -nw option). It worked fine in emacs22; and I'm not really sure whether I need to use emacs23... It's not just xterm: the same problem exists with $TERM=cygwin, for example.

  • Python c_types .dll functions (pari library)

    - by silinter
    Alright, so a couple days ago I decided to try and write a primitive wrapper for the PARI library. Ever since then I've been playing with ctypes library in loading the dll and accessing the functions contained using code similar to the following: from ctypes import * libcyg=CDLL("<path/cygwin1.dll") #It needs cygwin to be loaded. Not sure why. pari=CDLL("<path>/libpari-gmp-2.4.dll") print pari.fibo #fibonacci function #prints something like "<_FuncPtr object at 0x00BA5828>" So the functions are there and they can potentially be accessed, but I always recieve an access violation no matter what I try. For example: pari.fibo(5) #access violation pari.fibo(c_int(5)) #access violation pari.fibo.argtypes=[c_long] #setting arguments manually pari.fibo.restype=long #set the return type pari.fibo(byref(c_int(5))) #access violation reading 0x04 consistently and any variation on that, including setting argtypes to receive pointers. The Pari .dll is written in C and the fibonacci function's syntax within the library is GEN fibo(long x) (docs @http://pari.math.u-bordeaux.fr/dochtml/html/Arithmetic_functions.html#fibonacci, I need more rep it seems). Could it be the return type that's causing these errors, as it is not a standard int or long but a GEN type, which is unique to the PARI library? Any help would be appreciated. If anyone is able to successfully load the library and use ANY function from within python, please tell; I've been at this for hours now.

  • Ruby Gem Install question + answer(on windows vista Home Basic environment)

    - by Vamsi
    Recently I am having problems with installing rcov gem on my windows (vista Home Basic environment), so after googling I found one solution and that is gem install rcov -v 0.8.1.1.0 #version that installs without errors gem update rcov #update to the latest version, in my case rcov-0.8.1.2.0-x86-mswin32 But this solution didn't worked on my colleague's system (windows xp) and after that we came to know about RubyInstaller devkit for winddows But that dev kit is not working on my vista, when I tried gem install rcov in my command prompt, it game me this error, C:\Users\Vamsi>gem install rcov Building native extensions. This could take a while... ERROR: Error installing rcov: ERROR: Failed to build gem native extension.ERROR: Failed to build gem native extension. D:/Spritle/Programs/Ruby/bin/ruby.exe extconf.rb creating Makefile nmake 'nmake' is not recognized as an internal or external command, operable program or batch file.

Results logged to D:/Spritle/Programs/Ruby/lib/ruby/gems/1.8/gems/rcov-0.9.8/ext /rcovrt/gem_make.out So after that my colleague tried to install nmake as well but it was throwing some other error. Can some one suggest a better solution for solving this problems for all windows environments? I am aware of cygwin for windows but I am not sure that is an 100% solution either.

  • How to test a struts 2.1.x developer?

    - by Jason Pyeron
    We employ test to filter out those who can't. The tests are designed to be very low effort for those who can and too much effort for those who can't. Here is an example for java web application developer on an Oracle project: We only work with contractors who can use the tools we use, to determine if you can use the tools we have devised some very simple tests. Instructions If you are prepared and knowledgeable this will take you about 2-5 minutes. Suggested knowledge and tools: * subversion 1.6 see http://subversion.tigris.org/ or http://cygwin.com/setup.exe * java 1.6 see http://java.sun.com/javase/downloads/index.jsp * oracle >=10g see http://www.oracle.com/technology/software/products/jdev/index.html * j2ee server see http://tomcat.apache.org/download-55.cgi or http://www.jboss.org/jbossas/downloads/ Steps 1. check out svn://statics32.pdinc.us/home/subversion/guest 2. deploy the war file found at trunk/test.war 3. browse to the web application you installed from the war file and answer the one SQL question: How many rows are in the table 'testdata' where column 'value' ends with either an 'A' or an 'a'? The login credentials are in trunk/doc/oracle.txt 4. make a RESULTS HASH by submitting your answer to the form. 5. create a file in tmp/YourUserName.txt and put the RESULTS HASH in it, not the answer. 6. check in your file (don't forget to add the file first). 7. message me with the revision number of your check in. As such I am looking for ideas on how to test for someone to be a struts 2.1 w/ annotations.

  • Unable to access Java-created file -- sometimes

    - by BlairHippo
    In Java, I'm working with code running under WinXP that creates a file like this: public synchronized void store(Properties props, byte[] data) { try { File file = filenameBasedOnProperties(props); if ( file.exists() ) { return; } File temp = File.createTempFile("tempfile", null); FileOutputStream out = new FileOutputStream(temp); out.write(data); out.flush(); out.close(); file.getParentFile().mkdirs(); temp.renameTo(file); } catch (IOException ex) { // Complain and whine and stuff } } Sometimes, when a file is created this way, it's just about totally inaccessible from outside the code (though the code responsible for opening and reading the file has no problem), even when the application isn't running. When accessed via Windows Explorer, I can't move, rename, delete, or even open the file. Under Cygwin, I get the following when I ls -l the directory: ls: cannot access [big-honkin-filename] total 0 ?????????? ? ? ? ? ? [big-honkin-filename] As implied, the filenames are big, but under the 260-character max for XP (though they are slightly over 200 characters). To further add to the sense the my computer just wants me to feel stupid, sometimes the files created by this code are perfectly normal. The only pattern I've spotted is that once one file in the directory "locks", the rest are screwed. Anybody ever run into something like this before, or have any insights into what's going on here?

  • Advantages of Using Linux as primary developer desktop

    - by Nick N
    I want to get some input on some of the advantages of why developers should and need to use Linux as their primary development desktop on a daily basic as opposed to using Windows. This is particulary helpful when your Dev, QA, and Production environments are Linux. The current analogy that I keep coming back to is. If I build my demo car as a Ford Escort, but my project car is a Ford Mustang, it doesn't make sense at all. I'm currently at an IT department that allows dual boot with Windows and Linux, but some run Linux while the vast majority use Windows. Here's several advantages that I've came up with since using Linux as a primary desktop. Same Exact operating system as Dev, QA, and Production Same Scripts (.sh) instead of maintaining (.bat and *.sh). Somewhat mitigated by using cygwin, but still a bit different. Team learns simple commands such as: cd, ls, cat, top Team learns Advanced commands like: pkill, pgrep, chmod, su, sudo, ssh, scp Full access to installs typically for Linux, such as RPM, DEB installs just like the target environments. The list could go on and on, but I want to get some feedback of anything that I may have missed, or even any disadvantages (of course there are some). To me it makes sense to migrate an entire team over to using Linux, and using Virtual Box, running Windows XP VM's to test functional items that 95% of most of the world uses. This is similar but a little different thread going on here as well. link text

  • Basic C programming question

    - by Amit
    Hi all, I've just started to learn C and it's going pretty slow...I wanted to write a program that takes in an integer argument and returns it's doubled value (aka take in integer, multiply by 2, and printf that value). I purposely did not want to use the scanf function. Here's what I have so far and what is not compiling... #include <stdio.h> int main(int index) { if (!(index)) { printf("No index given"); return 1; } a = index*2; printf("Mult by 2 %d",a); return 0; } So basically when the program is executed I want to supply the index integer. So, in cygwin, I would write something like ./a 10 and 10 would be stored into the index variable. Also, I want to program to return "No index given" and exit if no index value was supplied... Anyone care to help what I'm doing wrong? EDIT: This code returns 1 error upon compilation and is based on the help by @James: #include <stdio.h> int main(int 1, char index) { int index, a; if (!(index)) { printf("No index given"); return 1; } a = index*2; printf("Mult by 2 %d",a); return 0; } Thanks! Amit

  • Can piping of screen to file change the result of a C++ code?

    - by Biga
    I am having this very weird behaviour with a C++ code: It gives me different results when running with and without piping the screen to a file (reproducible in cygwin and linux). I mean, if I get the same executable and run it like './run' or run it like './run out.log', I get different results! I use std::cout to output to screen, all lines ending with endl; I use ifstream for the input file; I use ofstream for output, all lines ending with endl. I am using g++ 4. Any idea what is going on? UPDATE: I have hard-coded the input data, so 'ifstream' is not used, and problem persists. UPDATE 2: That's getting interesting. I have output three variables that are computed initially, and that's what I get with and without piping direct to screen: 0 -0.02 0 piped: 0 -0.02 1.04083e-17 So there's a round-off difference with and without piping the output! Now, why piping would interefere with an internal computation of the code?

  • char[] and char* compatibility?

    - by Aerovistae
    In essence, will this code work? And before you say "Run it and see!", I just realized my cygwin didn't come with gcc and it's currently 40 minutes away from completing reinstallation. That being said: char* words[1000]; for(int i = 0; i<1000; i++) words[i] = NULL; char buffer[ 1024 ]; //omit code that places "ADD splash\0" into the buffer if(strncmp (buffer, "ADD ", 4){ char* temp = buffer + 4; printf("Adding: %s", temp); int i = 0; while(words[i] != NULL) i++; words[i] = temp; } I'm mostly uncertain about the line char* temp = buffer + 4, and also whether I can assign words[i] in the manner that I am. Am I going to get type errors when I eventually try to compile this in 40 minutes? Also-- if this works, why don't I need to use malloc() on each element of words[]? Why can I say words[i] = temp, instead of needing to allocate memory for words[i] the length of temp?

  • How do I distribute my slightly customized Linux in VirtualBox?

    - by goodrone
    Suppose I've got some Arch Linux installation which I'd like to distribute among students with (sometimes very) basic Linux knowledge to make them able to compile C programs in an environment very similar to that in the university. (Things like Cygwin or MinGW seem to be inappropriate here.) I also choose VirtualBox as a holder for the virtual system. The question is: how do I distribute it? I mean: installing VirtualBox on the target machine (if not still installed) uncompressing and copying my image file (.VDI) registering the image (so that VirtualBox could see it when launched) configuring the guest system in VirtualBox (network, memory, etc.) optionally installing PuTTY to simplify interfacing with the guest Linux Should I create an installer? Which one? Or just write some .BAT-scripts? (Target host system is Windows, mostly XP and Vista.) I definately don't want to have a webpage with screen shot explaining where to click and what to press, because it's boring. Additionaly, what will be the best (the most user-friendly) way to configure network when the guest Linux system is run for the first time?

  • Can redirection of screen output to file change the result of a C++ code?

    - by Biga
    I am having this very weird behaviour with a C++ code: It gives me different results when running with and without redirecting the screen output to a file (reproducible in cygwin and linux).

  • Segmentation fault on returning from main (very short and simple code, no arrays or pointers)

    - by Gábor Kovács
    I've been wondering why the following trivial code produces a segmentation fault when returning from main(): //Produces "Error while dumping state (probably corrupted stack); Segmentation fault" #include <iostream> #include <fstream> #include <vector> using namespace std; class Test { vector<int> numbers; }; int main() { Test a; ifstream infile; cout << "Last statement..." << endl; // this gets executed return 0; } Interestingly, 1) if only one of the two variables is declared, I don't get the error, 2) if I declare a vector variable instead of an object with a vector member, everything's fine, 3) if I declare an ofstream instead of an ifstream, again, everything works fine. Something appears to be wrong with this specific combination... Could this be a compiler bug? I use gcc version 3.4.4 with cygwin. Thanks for the tips in advance. Gábor

  • The proper way to script periodically pulling a page from an https site

    - by DarthShader
    I want to create a command-line script for Cygwin/Bash that logs into a site, navigates to a specific page and compares it with the results of the last run. So far, I have it working with Lynx like so: ----snpipped, just setting variables---- echo "# Command logfile created by Lynx 2.8.5rel.5 (29 Oct 2005) ----snipped the recorded keystrokes------- key Right Arrow key p key Right Arrow key ^U" >> $tmp1 #p, right arrow initiate the page saving #"type" the filename inside the "where to save" dialog for i in $(seq 0 $((${#tmp2} - 1))) do echo "key ${tmp2:$i:1}" >> $tmp1 done #hit enter and quit echo "key ^J key y key q key y " >> $tmp1 lynx -accept_all_cookies -cmd_script=$tmp1 https://thewebpage.com/login diff $tmp2 $oldComp mv $tmp2 $oldComp It definitely does not feel "right": the cmd_script consists of relative user actions instead of specifying the exact link names and actions. So, if anything on the site ever changes, switches places, or a new link is added - I will have to re-create the actions. Also, I can't check for any errors so I can't abort the script if something goes wrong (login failed, etc) Another alternative I have been looking at is Mechanize with Ruby (as a note - I have 0 experience with Ruby). What would be the best way to improve or rewrite this?

  • Problem deleting .svn directories on Windows XP

    - by John L
    I don't seem to have this problem on my home laptop with Windows XP, but then I don't do much work there. On my work laptop, with Windows XP, I have a problem deleting directories when it has directories that contain .svn directories. When it does eventually work, I have the same issue emptying the Recycle bin. The pop-up window says "Cannot remove folder text-base: The directory is not empty" or prop-base or other folder under .svn This continued to happen after I changed config of TortoiseSVN to stop the TSVN cache process from running and after a reboot of the system. Multiple tries will eventually get it done. But it is a huge annoyance because there are other issues I'm trying to fix, so I'm hoping it is related. 'Connected Backup PC' also runs on the laptop and the real problem is that cygwin commands don't always work. So I keep thinking the dot files and dot directories have something to do with both problems and/or the backup or other process scanning the directories is doing it. But I've run out of ideas of what to try or how to identify the problem further.

  • Which DVCS would work best on Windows for my scenario?

    - by PoorLuzer
    At work I use ClearCase and SourceSafe, but have found some time to do some time to code for myself enroute thanks to a disposable laptop. However, I wish I had a lightweight VCS on my system using which I would be able to make changes to my code during the commute and then push/grab them from my Linux systems. I use git on my home system, but I can't really get it working on Windows. I don't want all that cygwin hack. If it does not run natively on Windows, it just won't do. What have you guys tried on your Windows system? Something that YOU use. The big player at the moment seems to be Mercurial? What would be best for a one (or maybe two) man team? I just need to maintain : Versioned copies of source code. Checking in and out should be as less obtrusive as possible. I am looking forward to a multiple Undo kind of feature (like that in an EMacs buffer) but persistent. I really like the way git keeps track of lines moving between files in a source code set I should be able to move part(s)/sub tree(s) of the source tree (each sub tree implies a module/plugin to my the main software I am building) to an archival system either completly or partially and restore them back from the archive as and when required and the system should track any changes to this tree as well. I actually want to experiment with my code as much as possible without me manually keeping track of what I modified and what I need to undo once I try out some idea, so that I am back to where I want to continue from. Notes : A similar topic came up a year ago : http://stackoverflow.com/questions/4670/dvcs-choices-whats-good-for-windows I hope things have changed, and I really want people to share their own, real life experiences. Not something they recommend without using it or they think will work.

  • Optimize Duplicate Detection

    - by Dave Jarvis
    Background This is an optimization problem. Oracle Forms XML files have elements such as: <Trigger TriggerName="name" TriggerText="SELECT * FROM DUAL" ... /> Where the TriggerText is arbitrary SQL code. Each SQL statement has been extracted into uniquely named files such as: sql/module=DIAL_ACCESS+trigger=KEY-LISTVAL+filename=d_access.fmb.sql sql/module=REP_PAT_SEEN+trigger=KEY-LISTVAL+filename=rep_pat_seen.fmb.sql I wrote a script to generate a list of exact duplicates using a brute force approach. Problem There are 37,497 files to compare against each other; it takes 8 minutes to compare one file against all the others. Logically, if A = B and A = C, then there is no need to check if B = C. So the problem is: how do you eliminate the redundant comparisons? The script will complete in approximately 208 days. Script Source Code The comparison script is as follows: #!/bin/bash echo Loading directory ... for i in $(find sql/ -type f -name \*.sql); do echo Comparing $i ... for j in $(find sql/ -type f -name \*.sql); do if [ "$i" = "$j" ]; then continue; fi # Case insensitive compare, ignore spaces diff -IEbwBaq $i $j > /dev/null # 0 = no difference (i.e., duplicate code) if [ $? = 0 ]; then echo $i :: $j >> clones.txt fi done done Question How would you optimize the script so that checking for cloned code is a few orders of magnitude faster? System Constraints Using a quad-core CPU with an SSD; trying to avoid using cloud services if possible. The system is a Windows-based machine with Cygwin installed -- algorithms or solutions in other languages are welcome. Thank you!

  • How can I attach multiple urls to a single git remote?

    - by deterb
    I'm currently using git on windows through a combination of msysgit and Cygwin. I have a laptop which I move around quite a bit, so it's not on a consistent location. Unfortunately, I don't have a consistent name for it due to the computer name not being resolved on all of the locations I connect to, so I can't just use the computer name as the host for the url (e.g. git://compname/repo), so I have to use the IP address. Is there a way I can add multiple urls to pull from for a particular remote? I've seen git remote set-url --add [--push] <name> <newurl> as a way to add multiple URLs to a remote, and I can see the updates in the .git/config file, but git only tries to use the first one. Is there a way to get git to try to use all of the urls? I've tried both git fetch and git remote update, but neither tries anything after the first url. Note that I haven't tried this on linux yet, and I can't fix the computer name resolution as this is at work. Thanks

  • C++: What is the size of an object of an empty class?

    - by Ashwin
    I was wondering what could be the size of an object of an empty class. It surely could not be 0 bytes since it should be possible to reference and point to it like any other object. But, how big is such an object? I used this small program: #include <iostream> using namespace std; class Empty {}; int main() { Empty e; cerr << sizeof(e) << endl; return 0; } The output I got on both Visual C++ and Cygwin-g++ compilers was 1 byte! This was a little surprising to me since I was expecting it to be of the size of the machine word (32 bits or 4 bytes). Can anyone explain why the size of 1 byte? Why not 4 bytes? Is this dependent on compiler or the machine too? Also, can someone give a more cogent reason for why an empty class object will not be of size 0 bytes?

  • Rsync: windows 7, synology: login error and permission denied error

    - by loonboon
    Good day to all of you all, I'm running into strange/stupid errors, and I hope anybody would be so kind to help me out. I have to admit, I am by no means a guru, so please bear with me :-) Situation: -Synology NAS (runs Linux), and Windows 7 desktop (1 normal/restricted user Lisa and 1 admin user). - Data from W7 desktop to be rsynced to synology: /volume1/home/Lisa/Backup - Rsync command: c:\cygwin\bin\rsync -avz /cygdrive/e/Lisa/ [email protected]:/volume1/homes/Lisa/Backup - I've set up ssh per these two threads: a. http://www.cesareriva.com/archives/102 b. http://www.cesareriva.com/archives/112 Now the horrors begin: - root is allowed to run the rsync succesfully, however, he doesn't login automatically (so I can not use rsync in W7 batchscripts, which is of course required). - Lisa is allowed to login automatically but he can not succesfully finish the rsync command because of permission errors: rsync change dir /volume1/homes/Lisa/Backup failed: permissions denied. This happens for each and every file and subdir rsync tries to create. However, the main directory (Backup) is created. When I try to copy files from windows explorer to the directory 'Backup' using the very same user Lisa everything goes smoothly. So, obviously, there is a permission problem somewhere; either my rsync-command isn't correct, or the folder permissions for homes/Lisa aren't correct (but, then again, Windows 7 copies files to that folder without any problems, so that does make me believe the homes/Lisa-permissions don't appear to be the problem). I also tried adding: --chmod=Dugo+x --chmod=ugo+r which I found somewhere on the web, to the rsync-command, but this didn't solve any problem and gave the exact errors. Would anybody please please help me on how to fix this? I am utterly frustrated about this, because I have been trying for 1 month to get everything to work and it simply doesn't work. I bought the big Synology to end the horrors of 20 external USB-disks for once and for all (we have many pictures and home vids of our deceased dogs and want to watch these, the horrors being 'what material is on what disk'). I'll gladly return the favour of somebody helping me out by buying you a nice beer (paypal), if you could end my misery. I am not extremely skilled on Linux (not at all :-( ) so if you could give an extra word when possible so I understand what to do, I'd be very grateful. I really hope somebody can help me out, Thank you in advance, Lisa

  • batch file infinite loop when parsing file

    - by Bart
    Okay, this should be a really simple task but its proving to be more complicated than I think it should be. I'm clearly doing something wrong, and would like someone else's input. What I would like to do is parse through a file containing paths to directories and set permissions on those directories. An example line of the input file. There are several lines, all formatted the same way, with a different path to a directory. E:\stuff\Things\something else (X)\ (The file in question is generated under Cygwin using find to list all directories with "(X)" in the name. The file is then passed through unix2win to make it windows compatible. I've also tried manually creating the input file from within windows to rule out the file's creation method as the problem.) Here's where I'm stuck... I wrote the following quick and dirty batch file in Windows XP and it worked without any issues at all, but it will not work in server 2k8. Batch file code to run through the file and set permissions: FOR /F "tokens=*" %%A IN (dirlist.txt) DO echo y| cacls "%%A" /T /C /G "Domain Admins":f "Some Group":f "some-security-group":f What this is SUPPOSED to do (and does in XP) is loop through the specified file (dirlist.txt) and run cacls.exe on each directory it pulls from the file. The "echo y|" is in there to automagically confirm when cacls helpfully asks "are you sure?" for every directory in the list. Unfortunately, however, what it DOES is fall into an infinite loop. I've tried surrounding everything after "DO" with quotes, which prevents the endless loop but confuses cacls so it throws an error. Interestingly, I've tried running the code from after "DO" manually (obviously replacing the variable with the full path, copied straight from the file) at a command prompt and it runs as expected. I don't think it's the file or the loop, as adding quotes to the command to be executed prevents the loop from continuing past where it's supposed to... I really have no idea at this point. Any help would be appreciated. I have a feeling it's going to be something increadibly stupid... but I'm pulling my hair out so I thought I'd ask.

  • Persistent static routes fail on MacOS 10.6.5 startup!

    - by verbalicious
    I'm unable to get static routes to persist a reboot on Mac OS 10.6.5. I've tried all of the methods prescribed in Google search results, and previous posts on this site. I've tried manually creating a launchd daemon, and used RouteSplit's launchd daemon to no avail. It's clear that the interface is not ready when these methods attempt to apply the route. This workstation in question is getting its IP from DHCP and probably hasn't gotten its DHCP lease when the command runs. We're able to apply the route by hand when logged in, but not through startup methods. Is there another way to apply this route by sneaking the command into something later, but before the login window appears to the user? Here is some relevant log info from system.log. You can see the "route: writing to routing socket: Network is unreachable" errors where my launchd script fires off. I've tried adding extra "sleep" and "ipconfig waitall" statements later in the script but this doesn't fly.

  • Huawei b153 limit of devices

    - by bdecaf
    I set up my home network all through this 3G wifi router. Problem is it only allows 5 devices to connect. That's not much especially if a wifi printer and gaming consoles keep hogging these slots. On the other hand I don't see the point on blocking these devices. They are (should) not doing anything online just intern in my network. The documentation I can find is surpirisingly unhelpful and focuses how to plug the device in a power socket. So what would be my options. Notes: I have already been able to get a shell on the device using ssh. It's running some Busybox. But I fail to find the how and where this limit is enforced/created. Notes 2: Specifically my device is a 3WebCube - unfortunately not specifically marked with the Huawei Model number. Successes so far After enabling ssh in the options I can login: ssh -T [email protected] [email protected]'s password: ------------------------------- -----Welcome to ATP Cli------ ------------------------------- unfortunately because of this -T - the tab key does not work for autocomplete and all inputted commands will be echoed. Also no history with arrow keys. ATP interface this custom interface is not very useful: ATP>help help Welcome to ATP command line tool. If any question, please input "?" at the end of command.
