  • Industry-style practices for increasing productivity in a small scientific environment

    - by drachenfels
    Hi, I work in a small, independent scientific lab in a university in the United States, and it has come to my notice that, compared with a lot of practices that are ostensibly followed in the industry, like daily checkout into a version control system, use of a single IDE/editor for all languages (like emacs), etc, we follow rather shoddy programming practices. So, I was thinking of getting together all my programs, scripts, etc, and building a streamlined environment to increase productivity. I'd like suggestions from people on Stack Overflow for the same. Here is my primary plan.: I use MATLAB, C and Python scripts, and I'd like to edit, compile them from a single editor, and ensure correct version control. (questions/things for which I'd like suggestions are in italics) 1] Install Cygwin, and get it to work well with Windows so I can use git or a similar version control system (is there a DVCS which can work directly from the windows CLI, so I can skip the Cygwin step?). 2] Set up emacs to work with C, Python, and MATLAB files, so I can edit and compile all three at once from a single editor (say, emacs) (I'm not very familiar with the emacs menu, but is there a way to set the path to the compiler for certain languages? I know I can Google this, but emacs documentation has proved very hard for me to read so far, so I'd appreciate it if someone told me in simple language) 3] Start checking in code at the end of each day or half-day so as to maintain a proper path of progress of my code (two questions), can you checkout files directly from emacs? is there a way to checkout LabVIEW files into a DVCS like git? Lastly, I'd like to apologize for the rather vague nature of the question, and hope I shall learn to ask better questions over time. I'd appreciate it if people gave their suggestions, though, and point to any resources which may help me learn.

  • Debugging fortran code in Eclipse with Photran and GDB debugger: missing symbols

    - by tvandenbrande
    I have a program, written in fortran90, previously successfully compiled on a compaq compiler and working, that I'm now trying to compile with gfortran. I can compile the code to an .exe and run it. It works fine until a certain point in the routine and then an error is thrown. My current configuration: Windows 7 Eclipse Juno with CDT Photran Cygwin installation with gfortran compiler and GDB debugger (gdb.exe) Configurations for the debugger: GDB command set: Standard (Windows) Protocol: mi Shared libraries: don't load shared library symbols automatically (when activating this, no changes are noted). When running the debug command I get the following output: .gdbinit: No such file or directory. Reading symbols from /cygdrive/c/Users/thys/Documents/doctoraat/12_in progress/Hamfem/Debug/Hamfem.exe...done. auto-solib-add on Undefined command: "auto-solib-add". Try "help". Warning: C:/Users/thys/Documents/doctoraat/12_in progress/Hamfem/Hamfem/in: No such file or directory. [New Thread 5816.0x1914] [New Thread 5816.0x654] Basicly that leaves me with 2 questions: Where can I find the .gdbinit file in the cygwin installation? Are there any other possible errors in my setup, or points to think about?

  • Help regarding Android NDK

    - by Siva Kumar
    I am a beginner in using Android NDK. I am using Eclipse and I installed cygwin to build the c file to generate the .so file But while building the c file in cygwin I am always getting the error make: ***No rule to make target 'file.c' ... .Stop I tried building different C codes but for every file it says the same error .. Here is the source code: public class ndktest extends Activity { static { System.loadLibrary("ndkt"); } private native void helloLog(String logThis); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); helloLog("this is to test log file"); } } file.c void Java_com_ndktest_helloLog(JNIEnv * env, jobject this, jstring logThis) { jboolean isCopy; const char * szLogThis = (*env)->GetStringUTFChars(env, logThis, &isCopy); (*env)->ReleaseStringUTFChars(env, logThis, szLogThis); } And here is my Android.mk LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_LDLIBS := -llog LOCAL_MODULE := ndkt LOCAL_SRC_FILES := file.c include $(BUILD_SHARED_LIBRARY) I searched for the solution for the cause of error ... but nothing works for me. Can anyone tell me where I am making the mistake ? Thanks, Siva Kumar

  • lightweight/portable VCS for server-hopping DBA?

    - by Aaron
    I'm looking for a VCS that'll help me keep all of my work scripts in-sync. Requirements: Portable (as in flash drive, not code-level) Run on Windows XP and Server 2003+ No installation dependencies (Cygwin, perl, Python) I use Mercurial on my work machine for version control of the various T-SQL, ksh, perl, and CMD/BAT scripts that I maintain as a MS SQL Server DBA and Unix sysadmin. So far, hg has worked for my AIX boxes- I mount my home directory as I login, and deal with the repo as if it were local. I haven't been able to find a similar solution for the Windows machines I use. Most of them I do not have Local Admin rights; even if I did, I'd rather not install (and maintain) Python + Mercurial on all of them. I can't get to my home directory on them remotely, which leaves a client running on each machine as the only option. Bonus points for an answer that would let me use a single repo for both the Windows and Unix machines. :) I'm running WinXP, with heavy use of Cygwin and a CrunchBang VM.

  • Mono & DeflateStream

    - by ILya
    I have a simple code byte[] buffer = Encoding.UTF8.GetBytes("abracadabra"); MemoryStream ms = new MemoryStream(); DeflateStream ds = new DeflateStream(ms, CompressionMode.Compress, false); ms.Write(buffer, 0, buffer.Length); DeflateStream ds2 = new DeflateStream(ms, CompressionMode.Decompress, false); byte[] buffer2 = new byte[ms.Length]; ds2.Read(buffer2, 0, (int)ms.Length); Console.WriteLine(Encoding.UTF8.GetString(buffer2)); And when reading from ds2, i have the following: Stacktrace: at (wrapper managed-to-native) System.IO.Compression.DeflateStream.ReadZStream (intptr,intptr,int) <0x00004 at (wrapper managed-to-native) System.IO.Compression.DeflateStream.ReadZStream (intptr,intptr,int) <0x00004 at System.IO.Compression.DeflateStream.ReadInternal (byte[],int,int) [0x00031] in C:\cygwin\tmp\monobuild\build\BUILD\mono-2.6.3\mcs\class\System\System.IO.Compression\DeflateStream.cs:192 at System.IO.Compression.DeflateStream.Read (byte[],int,int) [0x00086] in C:\cygwin\tmp\monobuild\build\BUILD\mono-2.6.3\mcs\class\System\System.IO.Compression\DeflateStream.cs:214 at testtesttest.MainClass.Main (string[]) [0x00041] in C:\Users\ilukyanov\Desktop\Cassini\GZipDemo\Main.cs:27 at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. This problem appears in Mono 2.6.1 & 2.6.3... Is there any known way to successfully read from DeflateStream in Mono? Or maybe there are some third-party open-source assemblies with the same functionality?

  • Python ctypes in_dll string assignment

    - by ackdesha
    I could use some help assigning to a global C variable in DLL using ctypes. The following is an example of what I'm trying: test.c contains the following #include <stdio.h> char name[60]; void test(void) { printf("Name is %s\n", name); } On windows (cygwin) I build a DLL (Test.dll) as follows: gcc -g -c -Wall test.c gcc -Wall -mrtd -mno-cygwin -shared -W1,--add-stdcall-alias -o Test.dll test.o When trying to modify the name variable and then calling the C test function using the ctypes interface I get the following... >>> from ctypes import * >>> dll = windll.Test >>> dll <WinDLL 'Test', handle ... at ...> >>> f = c_char_p.in_dll(dll, 'name') >>> f c_char_p(None) >>> f.value = 'foo' >>> f c_char_p('foo') >>> dll.test() Name is Name is 48+? 13 Why does the test function print garbage in this case?

  • Free solution to backup folders to external SFTP server with shadow copy

    - by Sergiy Byelozyorov
    I have an account in university on Linux machine with 10TB of free space accessible via SFTP. I would like to backup my Windows 7 x64 laptop to university. Currently I am using rsync+cygwin, but backup is pretty slow (without shadow copy) and I hate console window appearing every day on my screen when I login. So I am looking for something like Windows Backup but with support for SFTP. Combination of tools will work too.

  • Ruby on rails gems and win 7

    - by cbrulak
    I have a networked home share (at work). This is my HOMEPATH,HOMESHARE,etc. When I installed the rails gem and other the .gems folder was created there (which is on a network drive) and consequently any code that needs a gem or a gem lookup is slow. And I'm wondering which environment variables need to be corrected. I've googled this but most results are dealing with cygwin so any ideas? Thanks

  • Start multiple instances of Firefox; Xephyr rootless mode

    - by Vi
    How can I have multiple independent instances of Mozilla Firefox 3.5 on the same X server, but started from different user accounts (consequently, different profiles)? Limited success was only with Xephyr :1, DISPLAY=:1 /usr/local/bin/firefox, but Xephyr has no Cygwin/X's "rootless" mode so it's not comfortable. The idea is to have one Firefox instance for various "Serious Business" things and the other for regular browsing with dozens of add-ons securely isolated.

    I'm having strange problem with my putty console. I'm establishing connection over ssh to my home computer [ windows 7 + freesshd server ]. Everything works just fine, but I'm getting this tiny screen with output, I can resize it of course, but the content is still in small box [ content doesn't resize ] I've tried to change the number of columns and rows in properties, but it didn't change anything. The same thing is with cygwin client.

  • Spaces and Parenthesis in windows PATH variable screws up batch files.

    - by NoName
    So, my path variable (System-Adv Settings-Env Vars-System-PATH) is set to: C:\Python26\Lib\site-packages\PyQt4\bin; %SystemRoot%\system32; %SystemRoot%; %SystemRoot%\System32\Wbem; %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\; C:\Python26\; C:\Python26\Scripts\; C:\cygwin\bin; "C:\PathWithSpaces\What_is_this_bullshit"; "C:\PathWithSpaces 1.5\What_is_this_bullshit_1.5"; "C:\PathWithSpaces (2.0)\What_is_this_bullshit_2.0"; "C:\Program Files (x86)\IronPython 2.6"; "C:\Program Files (x86)\Subversion\bin"; "C:\Program Files (x86)\Git\cmd"; "C:\Program Files (x86)\PuTTY"; "C:\Program Files (x86)\Mercurial"; Z:\droid\android-sdk-windows\tools; Although, obviously, without the newlines. Notice the lines containing PathWithSpaces - the first has no spaces, the second has a space, and the third has a space followed by a parenthesis. Now, notice the output of this batch file: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\>vcvars32.bat C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin>"C:\Program Files (x86 )\Microsoft Visual Studio 9.0\Common7\Tools\vsvars32.bat" Setting environment for using Microsoft Visual Studio 2008 x86 tools. \What_is_this_bullshit_2.0";"C:\Program was unexpected at this time.

So, what is this bullshit? Specifically: Directory in path that is properly escaped with quotes, but with no spaces = fine Directory in path that is properly escaped with quotes, and has spaces but no parenthesis = fine Directory in path that is properly escaped with quotes, and has spaces and has a parenthesis = ERROR Whats going on here? How can I fix this? I'll probably resort to a junction point to let my tools still work as workaround, but if you have any insight into this, please let me know :)

  • What is the best way to run emacs under Windows?

    - by Zubair
    I tried using the GNU Emacs download, unzipped it and then clicked on emacs.exe, but got some obscure error. Then I tried Cygwin emacs, but when I press ctrl x ctrl c to quit emacs it thinks I pressed ctrl x ctrl "g"!!! I checked all the key mapping and they work otherwise in Emacs. Is there another version of emacs for windows that just works!

  • How do I change colors on-the-fly in mintty?

    - by Thomas L Holaday
    How do I change the colors in a Cygwin mintty session which is already open? Is it possible? Use case: Under environment-imposed time constraints, multiple terminal windows have been opened without forethought. In order to reduce the risk of typing the commands for system A into the terminal for system B, it would be nice if they were different colors. Is there some escape sequence or whatnot that can change the color scheme for a running session?

  • Windows - How to remotely watch log files

    - by weismat
    I would like to look at some log files solely via the console on a standard Windows 7 machine. The logs are created by schedulded tasks and I find it a hazzle to use VNC for this purpose. What technology should I look at? Powershell, Cygwin via ssh or something else? The log files are written using log4Net - thus there might also be an easy way to reconfigure it to create events or something else for remote display.

  • Windows7: Gaining administrator rights in CLI without being prompted for password

    - by liori
    Hello, I am trying to write a script which includes disk defragmentation as one of its steps. defrag needs administrative rights to work. I tried to use runas /user:Administrator, but it always asked me for password (even though there isn't one set). The script needs to run unattended for a long time, and it needs to be started from standard user account (it is actually being run by cygwin), so I'd like to get rid of that prompt. Is this possible? Thanks,

  • Reliable file copy (move) process - mostly Unix/Linux

    - by mfinni
    Short story : We have a need for a rock-solid reliable file mover process. We have source directories that are often being written to that we need to move files from. The files come in pairs - a big binary, and a small XML index. We get a CTL file that defines these file bundles. There is a process that operates on the files once they are in the destination directory; that gets rid of them when it's done. Would rsync do the best job, or do we need to get more complex? Long story as follows : We have multiple sources to pull from : one set of directories are on a Windows machine (that does have Cygwin and an SSH daemon), and a whole pile of directories are on a set of SFTP servers (Most of these are also Windows.) Our destinations are a list of directories on AIX servers. We used to use a very reliable Perl script on the Windows/Cygwin machine when it was our only source. However, we're working on getting rid of that machine, and there are other sources now, the SFTP servers, that we cannot presently run our own scripts on. For security reasons, we can't run the copy jobs on our AIX servers - they have no access to the source servers. We currently have a homegrown Java program on a Linux machine that uses SFTP to pull from the various new SFTP source directories, copies to a local tmp directory, verifies that everything is present, then copies that to the AIX machines, and then deletes the files from the source. However, we're finding any number of bugs or poorly-handled error checking. None of us are Java experts, so fixing/improving this may be difficult. Concerns for us are: With a remote source (SFTP), will rsync leave alone any file still being written? Some of these files are large. From reading the docs, it seems like rysnc will be very good about not removing the source until the destination is reliably written. Does anyone have experience confirming or disproving this? Additional info We will be concerned about the ingestion process that operates on the files once they are in the destination directory. We don't want it operating on files while we are in the process of copying them; it waits until the small XML index file is present. Our current copy job are supposed to copy the XML file last. Sometimes the network has problems, sometimes the SFTP source servers crap out on us. Sometimes we typo the config files and a destination directory doesn't exist. We never want to lose a file due to this sort of error. We need good logs If you were presented with this, would you just script up some rsync? Or would you build or buy a tool, and if so, what would it be (or what technologies would it use?) I (and others on my team) are decent with Perl.

  • What is the Windows analog of the Linux watch command?

    - by PeterJCLaw
    I'm looking for a Windows program/script/command line function that works like Linux's watch program. watch periodically calls another program/whatever and shows the result, which is great for refreshing an output file or similar every second: watch cat my-output.txt or, more powerfully: watch grep "fail" my-output.txt I've looked for it in cygwin's library, but it doesn't seem to be present.
