  • Git for beginners: The definitive practical guide

    - by Adam Davis
    Ok, after seeing this post by PJ Hyett, I have decided to skip to the end and go with git. So what I need is a beginners practical guide to git. "Beginner" being defined as someone who knows how to handle their compiler, understands to some level what a makefile is, and has touched source control without understanding it very well. "Practical" being defined as this person doesn't want to get into great detail regarding what git is doing in the background, and doesn't even care (or know) that it's distributed. Your answers might hint at the possibilities, but try to aim for the beginner that wants to keep a 'main' repository on a 'server' which is backed up and secure, and treat their local repository as merely a 'client' resource. Procedural note: PLEASE pick one and only one of the below topics and answer it clearly and concisely in any given answer. Don't try to jam a bunch of information into one answer. Don't just link to other resources - cut and paste with attribution if copyright allows, otherwise learn it and explain it in your own words (ie, don't make people leave this page to learn a task). Please comment on, or edit, an already existing answer unless your explanation is very different and you think the community is better served with a different explanation rather than altering the existing explanation. So: Installation/Setup How to install git How do you set up git? Try to cover linux, windows, mac, think 'client/server' mindset. Setup GIT Server with Msysgit on Windows How do you create a new project/repository? How do you configure it to ignore files (.obj, .user, etc) that are not really part of the codebase? Working with the code How do you get the latest code? How do you check out code? How do you commit changes? How do you see what's uncommitted, or the status of your current codebase? How do you destroy unwanted commits? How do you compare two revisions of a file, or your current file and a previous revision? How do you see the history of revisions to a file? How do you handle binary files (visio docs, for instance, or compiler environments)? How do you merge files changed at the "same time"? How do you undo (revert or reset) a commit? Tagging, branching, releases, baselines How do you 'mark' 'tag' or 'release' a particular set of revisions for a particular set of files so you can always pull that one later? How do you pull a particular 'release'? How do you branch? How do you merge branches? How do you resolve conflicts and complete the merge? How do you merge parts of one branch into another branch? What is rebasing? How do I track remote branches? How can I create a branch on a remote repository? Other Describe and link to a good gui, IDE plugin, etc that makes git a non-command line resource, but please list its limitations as well as its good. msysgit - Cross platform, included with git gitk - Cross platform history viewer, included with git gitnub - OS X gitx - OS X history viewer smartgit - Cross platform, commercial, beta tig - console GUI for Linux qgit - GUI for Windows, Linux Any other common tasks a beginner should know? Git Status tells you what you just did, what branch you have, and other useful information How do I work effectively with a subversion repository set as my source control source? Other git beginner's references git guide git book git magic gitcasts github guides git tutorial Progit - book by Scott Chacon Git - SVN Crash Course Delving into git Understanding git conceptually I will go through the entries from time to time and 'tidy' them up so they have a consistent look/feel and it's easy to scan the list - feel free to follow a simple "header - brief explanation - list of instructions - gotchas and extra info" template. I'll also link to the entries from the bullet list above so it's easy to find them later.

  • Cross Compiling Boost for use on the Gumstix Overo with GumROS

    - by amelim
    I'm trying to cross-compile boost for use with the ROS framework on a Gumstix Overo. I've been following the posted instructions here (modifying the script when need be), however I've come across an issue where bjam will not compile boost properly. I call bjam as follows: # boost if [ ! -f /opt/gumros/lib/libboost_date_time-gcc41-mt-1_38.so ] ; then if [ ! -f boost_1_38_0.tar.gz ] ; then wget --tries=10 http://heanet.dl.sourceforge.net/sourceforge/boost/boost_1_38_0.tar.gz fi # tar xzf boost_1_38_0.tar.gz cd boost_1_38_0 GPP_PATH=${OVEROTOP}/tmp/cross/armv7a/arm-angstrom-linux-gnueabi/bin/g++ GPP_VER=`${GPP_PATH} -v 2>&1 | tail -1 | awk '{print $3}'` echo "using gcc : ${GPP_VER} : ${GPP_PATH} ; " > tools/build/v2/user-config.jam sudo apt-get install bjam set +o errexit sudo bjam --toolset=gcc-${GPP_VER} --prefix=/opt/gumros --with-date_time install set -o errexit cd .. else echo "boost appears to be already installed; skipping." fi if [ ! -f /opt/gumros/lib/libboost_date_time-gcc41-mt-1_38.so ] ; then echo "Failed to compile libboost_date_time"; exit; fi I've checked the user-config to make sure everything was kosher as well as making sure the GPP_PATH is correct. However, when I run the scrip I come across compilation errors such as: Reading package lists... Done Building dependency tree Reading state information...

  • Python and mechanize login script

    - by Perun
    Hi fellow programmers! I am trying to write a script to login into my universities "food balance" page using python and the mechanize module... This is the page I am trying to log into: http://www.wcu.edu/11407.asp The website has the following form to login: <FORM method=post action=https://itapp.wcu.edu/BanAuthRedirector/Default.aspx><INPUT value=https://cf.wcu.edu/busafrs/catcard/idsearch.cfm type=hidden name=wcuirs_uri> <P><B>WCU ID Number<BR></B><INPUT maxLength=12 size=12 type=password name=id> </P> <P><B>PIN<BR></B><INPUT maxLength=20 type=password name=PIN> </P> <P></P> <P><INPUT value="Request Access" type=submit name=submit> </P></FORM> From this we know that I need to fill in the following fields: 1. name=id 2. name=PIN With the action: action=https://itapp.wcu.edu/BanAuthRedirector/Default.aspx This is the script I have written thus far: #!/usr/bin/python2 -W ignore import mechanize, cookielib from time import sleep url = 'http://www.wcu.edu/11407.asp' myId = '11111111111' myPin = '22222222222' # Browser #br = mechanize.Browser() #br = mechanize.Browser(factory=mechanize.DefaultFactory(i_want_broken_xhtml_support=True)) br = mechanize.Browser(factory=mechanize.RobustFactory()) # Use this because of bad html tags in the html... # Cookie Jar cj = cookielib.LWPCookieJar() br.set_cookiejar(cj) # Browser options br.set_handle_equiv(True) br.set_handle_gzip(True) br.set_handle_redirect(True) br.set_handle_referer(True) br.set_handle_robots(False) # Follows refresh 0 but not hangs on refresh > 0 br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1) # User-Agent (fake agent to google-chrome linux x86_64) br.addheaders = [('User-agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11'), ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'), ('Accept-Encoding', 'gzip,deflate,sdch'), ('Accept-Language', 'en-US,en;q=0.8'), ('Accept-Charset', 'ISO-8859-1,utf-8;q=0.7,*;q=0.3')] # The site we will navigate into br.open(url) # Go though all the forms (for debugging only) for f in br.forms(): print f # Select the first (index two) form br.select_form(nr=2) # User credentials br.form['id'] = myId br.form['PIN'] = myPin br.form.action = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx' # Login br.submit() # Wait 10 seconds sleep(10) # Save to a file f = file('mycatpage.html', 'w') f.write(br.response().read()) f.close() Now the problem... For some odd reason the page I get back (in mycatpage.html) is the login page and not the expected page that displays my "cat cash balance" and "number of block meals" left... Does anyone have any idea why? Keep in mind that everything is correct with the header files and while the id and pass are not really 111111111 and 222222222, the correct values do work with the website (using a browser...) Thanks in advance EDIT Another script I tried: from urllib import urlopen, urlencode import urllib2 import httplib url = 'https://itapp.wcu.edu/BanAuthRedirector/Default.aspx' myId = 'xxxxxxxx' myPin = 'xxxxxxxx' data = { 'id':myId, 'PIN':myPin, 'submit':'Request Access', 'wcuirs_uri':'https://cf.wcu.edu/busafrs/catcard/idsearch.cfm' } opener = urllib2.build_opener() opener.addheaders = [('User-agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11'), ('Accept', 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8'), ('Accept-Encoding', 'gzip,deflate,sdch'), ('Accept-Language', 'en-US,en;q=0.8'), ('Accept-Charset', 'ISO-8859-1,utf-8;q=0.7,*;q=0.3')] request = urllib2.Request(url, urlencode(data)) open("mycatpage.html", 'w').write(opener.open(request)) This has the same behavior...

  • urllib2 misbehaving with dynamically loaded content

    - by Sheena
    Some Code headers = {} headers['user-agent'] = 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0' headers['Accept'] = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' headers['Accept-Language'] = 'en-gb,en;q=0.5' #headers['Accept-Encoding'] = 'gzip, deflate' request = urllib.request.Request(sURL, headers = headers) try: response = urllib.request.urlopen(request) except error.HTTPError as e: print('The server couldn\'t fulfill the request.') print('Error code: {0}'.format(e.code)) except error.URLError as e: print('We failed to reach a server.') print('Reason: {0}'.format(e.reason)) else: f = open('output/{0}.html'.format(sFileName),'w') f.write(response.read().decode('utf-8')) A url http://groupon.cl/descuentos/santiago-centro The situation Here's what I did: enable javascript in browser open url above and keep an eye on the console disable javascript repeat step 2 use urllib2 to grab the webpage and save it to a file enable javascript open the file with browser and observe console repeat 7 with javascript off results In step 2 I saw that a whole lot of the page content was loaded dynamically using ajax. So the HTML that arrived was a sort of skeleton and ajax was used to fill in the gaps. This is fine and not at all surprising Since the page should be seo friendly it should work fine without js. in step 4 nothing happens in the console and the skeleton page loads pre-populated rendering the ajax unnecessary. This is also completely not confusing in step 7 the ajax calls are made but fail. this is also ok since the urls they are using are not local, the calls are thus broken. The page looks like the skeleton. This is also great and expected. in step 8: no ajax calls are made and the skeleton is just a skeleton. I would have thought that this should behave very much like in step 4 question What I want to do is use urllib2 to grab the html from step 4 but I cant figure out how. What am I missing and how could I pull this off? To paraphrase If I was writing a spider I would want to be able to grab plain ol' HTML (as in that which resulted in step 4). I dont want to execute ajax stuff or any javascript at all. I don't want to populate anything dynamically. I just want HTML. The seo friendly site wants me to get what I want because that's what seo is all about. How would one go about getting plain HTML content given the situation I outlined? To do it manually I would turn off js, navigate to the page and copy the html. I want to automate this. stuff I've tried I used wireshark to look at packet headers and the GETs sent off from my pc in steps 2 and 4 have the same headers. Reading about SEO stuff makes me think that this is pretty normal otherwise techniques such as hijax wouldn't be used. Here are the headers my browser sends: Host: groupon.cl User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-gb,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Here are the headers my script sends: Accept-Encoding: identity Host: groupon.cl Accept-Language: en-gb,en;q=0.5 Connection: close Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 User-Agent: User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0 The differences are: my script has Connection = close instead of keep-alive. I can't see how this would cause a problem my script has Accept-encoding = identity. This might be the cause of the problem. I can't really see why the host would use this field to determine the user-agent though. If I change encoding to match the browser request headers then I have trouble decoding it. I'm working on this now... watch this space, I'll update the question as new info comes up

  • How to build android cts? And how to add and run your test case?

    - by Leox
    From 2.0 the cts is freely downloadable from android's repository. But there is no documents about it. Does anyone can tell me: how to build cts? Is there a standard procedure? How to run cts? How to add customized test case? Here, share my experience. After repo sync all source, you can't directly run "make" to build all source. You will get some errors. Now, I'am trying to first build android source without cts, and then build cts alone. Also, here are some reference for run cts: http://i-miss-erin.blogspot.com/2010/05/how-to-add-test-plan-package-to-android.html www.mentby.com/chenny/how-does-cts-work-where-can-i-get-the-test-streams.html www.jxva.com/?act=blog!article&articleId=157 1st time Update @ 5-13 18:39 +8:00 I do the following steps: 1.build android source without cts (move cts out of the $SDK_ROOT). 2.build cts (move cts back). both jdk1.5 and 1.6 have the following errors: 1.The 1st time "make cts" report: "Caused by: java.io.FileNotFoundException: ...(Too many open files)" 2.The 2nd time "make cts" report: "acp: file 'out/host/linux-x86/obj/EXECUTABLES/vm-tests_intermediates/tests/data' does not exist" 3.The 3rd time "make cts" report: "/bin/bash: line 0: cd: out/host/linux-x86/obj/EXECUTABLES/vm-tests_intermediates/hostjunit_files/classes: No such file or directory" 4.The last time "make cts" report: "zip error: Nothing to do!

  • Authenticating Windows 7 against MIT Kerberos 5

    - by tommed
    Hi There, I've been wracking my brains trying to get Windows 7 authenticating against a MIT Kerberos 5 Realm (which is running on an Arch Linux server). I've done the following on the server (aka dc1): Installed and configured a NTP time server Installed and configured DHCP and DNS (setup for the domain tnet.loc) Installed Kerberos from source Setup the database Configured the keytab Setup the ACL file with: *@TNET.LOC * Added a policy for my user and my machine: addpol users addpol admin addpol hosts ank -policy users [email protected] ank -policy admin tom/[email protected] ank -policy hosts host/wdesk3.tnet.loc -pw MYPASSWORDHERE I then did the following to the windows 7 client (aka wdesk3): Made sure the ip address was supplied by my DHCP server and dc1.tnet.loc pings ok Set the internet time server to my linux server (aka dc1.tnet.loc) Used ksetup to configure the realm: ksetup /SetRealm TNET.LOC ksetup /AddKdc dc1.tnet.loc ksetip /SetComputerPassword MYPASSWORDHERE ksetip /MapUser * * After some googl-ing I found that DES encryption was disabled by Windows 7 by default and I turned the policy on to support DES encryption over Kerberos Then I rebooted the windows client However after doing all that I still cannot login from my Windows client. :( Looking at the logs on the server; the request looks fine and everything works great, I think the issue is that the response from the KDC is not recognized by the Windows Client and a generic login error appears: "Login Failure: User name or password is invalid". The log file for the server looks like this (I tail'ed this so I know it's happening when the Windows machine attempts the login): If I supply an invalid realm in the login window I get a completely different error message, so I don't think it's a connection problem from the client to the server? But I can't find any error logs on the Windows machine? (anyone know where these are?) If I try: runas /netonly /user:[email protected] cmd.exe everything works (although I don't get anything appear in the server logs, so I'm wondering if it's not touching the server for this??), but if I run: runas /user:[email protected] cmd.exe I get the same authentication error. Any Kerberos Gurus out there who can give me some ideas as to what to try next? pretty please?

  • Programming activities for high school kids who have no idea what CS or programming is

    - by pointdxt
    I work at a small high school that's in a very high poverty area. There are only a handful of seniors that are thinking about applying to be an engineer of some sort in college and only 1 kid that applied for Computer Science (he has a couple acceptances so far!). He's been talking to me a lot as I majored in Computer Science as well and he is very excited about it. Unfortunately, our school doesn't have a Computer Science course of any kind so he asks me a lot of stuff. I want to help him out since he's really excited about majoring in CS but I don't know where to begin. I could say put Linux on a computer, go online and go research stuff like I did but this kid needs some direction and he doesn't even know what Linux is let alone have a free computer around for that sort of thing. He doesn't know much about CS but is keenly interested in having a computer do all sorts of things but I don't know how to help him in a meaningful way. Any advice? I'm not a teacher at the school so I'm not a great educator, I do IT at the school.

  • Java Runtime.getRuntime().exec() alternatives

    - by twilbrand
    I have a collection of webapps that are running under tomcat. Tomcat is configured to have as much as 2 GB of memory using the -Xmx argument. Many of the webapps need to perform a task that ends up making use of the following code: Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(command); process.waitFor(); ... The issue we are having is related to the way that this "child-process" is getting created on Linux (Redhat 4.4 and Centos 5.4). It's my understanding that an amount of memory equal to the amount tomcat is using needs to be free in the pool of physical (non-swap) system memory initially for this child process to be created. When we don't have enough free physical memory, we are getting this: java.io.IOException: error=12, Cannot allocate memory at java.lang.UNIXProcess.<init>(UNIXProcess.java:148) at java.lang.ProcessImpl.start(ProcessImpl.java:65) at java.lang.ProcessBuilder.start(ProcessBuilder.java:452) ... 28 more My questions are: 1) Is it possible to remove the requirement for an amount of memory equal to the parent process being free in the physical memory? I'm looking for an answer that allows me to specify how much memory the child process gets or to allow java on linux to access swap memory. 2) What are the alternatives to Runtime.getRuntime().exec() if no solution to #1 exists? I could only think of two, neither of which is very desirable. JNI (very un-desirable) or rewriting the program we are calling in java and making it it's own process that the webapp communicates with somehow. There has to be others. 3) Is there another side to this problem that I'm not seeing that could potentially fix it? Lowering the amount of memory used by tomcat is not an option. Increasing the memory on the server is always an option, but seems like more a band-aid. Servers are running java 6.

  • C: Running Unix configure file in Windows

    - by Shiftbit
    I would like to port a few applications that I use on Linux to Windows. In particular I have been working on wdiff. A program that compares the differences word by word of two files. Currently I have been able to successfully compile the program on windows through Cygwin. However, I would like to run the program natively on Windows similar to the Project: UnixUtils. How would I go about porting unix utilities on a windows environment? My possible guess it to manually create the ./configure file so that I can create a proper makefile. Am I on the right track? Has anyone had experience porting GNU software to windows? Update: I've compiled it on Code::Blocks and I get two errors: wdiff.c|226|error: `SIGPIPE' undeclared (first use in this function) readpipe.c:71: undefined reference to `_pipe' readpipe.c:74: undefined reference to `_fork This is a linux signal that is not supported by windows... equvilancy? wdiff.c|1198|error: `PRODUCT' undeclared (first use in this function)| this is in the configure.in file... hardcode would probably be the fastest solution... Outcome: MSYS took care of the configure problems, however MinGW couldnt solve the posix issues. I attempt to utilize pthreads as recommended by mrjoltcola. However, after several hours I couldnt get it to compile nor link using the provided libraries. I think if this had worked it would have been the solution I was after. Special mention to Michael Madsen for MSYS.

  • How to improve Java perfomance on Informix for Windows

    - by Michal Niklas
    I have problem with performance of Java UDR functions on Informix on Windows. On this server I already have some functions in C and SPL. I chose one function to write it in those 3 languages and I measured performance of this function on test table. Function calculates some kind of checksum so it not use any db libraries etc. only string and math operations. I observed performance on 30k records with SQL like: select function(txt) from _tmp_perf_test and I changed function to 'function_c, function_spl or function_java. My performance tests showed that C function is the fastest, SPL function is about 5 times slower, where Java is 100 (one hundred!) times slower than C. I checked it few times and 1:100 ratio didn't improve. I changed Java function to simply return length of the string but even this do not help so it looks, that there is general problem with Java function invocation, because there was no difference in time between Java function that calculate checksum and Java function that returns length of the string. I increased JVM_MAX_HEAP_SIZE to 128 and it not helped too. I use IBM Informix Dynamic Server Version 11.50.TC6DE. The same test on Linux server: IBM Informix Dynamic Server Version 11.50.FC6 show more "normal" results, i.e. Java is slower from C and SPL but only 2 to 5 times. What can I do to improve Java performance on Informix server on Windows?

  • Large number of simultaneous long-running operations in Qt

    - by Hostile Fork
    I have some long-running operations that number in the hundreds. At the moment they are each on their own thread. My main goal in using threads is not to speed these operations up. The more important thing in this case is that they appear to run simultaneously. I'm aware of cooperative multitasking and fibers. However, I'm trying to avoid anything that would require touching the code in the operations, e.g. peppering them with things like yieldToScheduler(). I also don't want to prescribe that these routines be stylized to be coded to emit queues of bite-sized task items...I want to treat them as black boxes. For the moment I can live with these downsides: Maximum # of threads tend to be O(1000) Cost per thread is O(1MB) To address the bad cache performance due to context-switches, I did have the idea of a timer which would juggle the priorities such that only idealThreadCount() threads were ever at Normal priority, with all the rest set to Idle. This would let me widen the timeslices, which would mean fewer context switches and still be okay for my purposes. Question #1: Is that a good idea at all? One certain downside is it won't work on Linux (docs say no QThread::setPriority() there). Question #2: Any other ideas or approaches? Is QtConcurrent thinking about this scenario? (Some related reading: how-many-threads-does-it-take-to-make-them-a-bad-choice, many-threads-or-as-few-threads-as-possible, maximum-number-of-threads-per-process-in-linux)

  • URL Encoding using C#

    - by masfenix
    I have an application which I've developed for a friend. It sends a POST request to the VB forum software and logs someone in (with out setting cookies or anything). Once the user is logged in I create a variable that creates a path on their local machine. c:\tempfolder\date\username The problem is that some usernames are throwing "Illegal chars" exception. For example if my username was mas|fenix it would throw an exception.. Path.Combine( _ Environment.GetFolderPath(System.Environment.SpecialFolder.CommonApplicationData), _ DateTime.Now.ToString("ddMMyyhhmm") + "-" + form1.username) I don't want to remove it from the string, but a folder with their username is created through FTP on a server. And this leads to my second question. If I am creating a folder on the server can I leave the "illegal chars" in? I only ask this because the server is Linux based, and I am not sure if Linux accepts it or not.. EDIT: It seems that URL encode is NOT what I want.. Here's what I want to do: old username = mas|fenix new username = mas%xxfenix Where %xx is the ASCII value or any other value that would easily identify the character.

  • Problem compiling gnustep-gui-0.16.0 undefined reference to png_sizeof

    - by stefanB
    I'm trying to compile GNUstep on a linux box but gnustep-gui-0.16.0 package is failing. I downloaded GNUstep Startup stable 0.20.1 (http://wwwmain.gnustep.org/resources/downloads.php)and follow instructions about how to compile (./configure && make). I'm getting this error: libgnustep-gui.so: undefined reference to 'png_sizeof' I have compiled latest libpng (1.2.34) and I can see that png_sizeof is defined as macro. However, I'm not quite sure how to fix the gnustep-gui-0.16.0 build. I tried to pass the include/lib directory where libpng is installed to configure build but nothing seems to help. I have quite up to date linux box but using gcc 3.3 (upgrade is not an option - but this should not be a problem). Full error: Making all for tool set_show_service...

Linking tool set_show_service ... ../Source/./obj/libgnustep-gui.so: undefined reference to `png_sizeof' collect2: ld returned 1 exit status gmake[3]: *** [obj/set_show_service] Error 1 gmake[2]: *** [set_show_service.all.tool.variables] Error 2 gmake[1]: *** [internal-all] Error 2 gmake[1]: Leaving directory `/home/bla/local/src/gnustep-startup-0.22.0/build/gnustep-gui-0.16.0' gmake[3]: *** [obj/set_show_service] Error 1 gmake[2]: *** [set_show_service.all.tool.variables] Error 2 gmake[1]: *** [internal-all] Error 2 Any suggestions?

  • ELF: linking: Why do I get undefined references in .so files

    - by ki.lya.online.fr
    Hi, I'm trying to build a program against wxWidgets, and I get a linker error. I'd like to really understand what it means. The error is: /usr/lib/libwx_baseu-2.8.so: undefined reference to `std::ctype<char>::_M_widen_init() const@GLIBCXX_3.4.11' What I don't understand is why the error is at libwx_baseu-2.8.so. I thought that .so files had all its symbols resolved, contrary to .o files that still need linking. When I ldd the .so, I get can resolve all its linked libraries, so there is no problem there: $ ldd /usr/lib/libwx_baseu-2.8.so linux-gate.so.1 => (0x00476000) libz.so.1 => /lib/libz.so.1 (0x00d9c000) libdl.so.2 => /lib/libdl.so.2 (0x002a8000) libm.so.6 => /lib/libm.so.6 (0x00759000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x002ad000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x0068d000) libpthread.so.0 => /lib/libpthread.so.0 (0x006f0000) libc.so.6 => /lib/libc.so.6 (0x00477000) /lib/ld-linux.so.2 (0x007f6000) Does it means that the .so file was not compiled correctly (in that case, it's a bug in my distribution package) or does it means that there are missing libraries on the linker command line for my particular program? Additionally, do you know how I can get a list on undefined symbols in an ELF file. I tried readelf -s but I can't find the missing symbol. Thank you. Mildred

  • Source Control Manager Backend

    - by Gabriel Parenza
    Hi Friends, What do you think is a better approach for Source Control Manager Backend. I am weighing File system vs Hosted Subversion service. Hosted Subversion-- (My company already has another group taking care of this) Advantages: * Zero maintenance on our end * Auto-backup and recovery * Reliability by auto-backup and file redundancy. * File history view in built, file merge, file diff On the other hand, while File system does not have the featured mentioned above but is much more simpler. Moreover, if files are hosted on Linux machine, which is backed up, it takes care of file system crash issues. Subversion will need working copies, which are going to be on this same Linux machine, and hence the need to not have an extra layer. Folks, I am looking for stronger reasons why I should take Subversion instead of keeping thing simple and going with File System. Let me know your opinions. Very thanks in advance, Gabriel. PS: I have explored few Commercial Source Manager, and have decide to go this route as it better suits our need.

  • cannot receive UDP broadcast packets

    - by user292792
    Hello I have 2 boxes: - an embedded device (ARM Omap with linux) which I'll call "Omap". - a PC (can either be Windows or linux). Scenario 1 Both boxes are in the same network (example: my office). The Omap gets its address from a DHCP server (ex: 192.168.10.110). The PC has always the same address (ex. 192.168.10.104). I can successfully exchange UDP broadcast packets on any port. Success. Scenario 2 The 2 boxes are in a network withOUT a DHCP server. The PC has a static IP address (example: 10.10.10.20). The Omap boots, looks for a DHCP server, doesn't find it, and is in what I call "bad IP address" state. Now... Broadcasting UDP packets from the Omap works: the PC can see them. The opposite doesn't work: UDP packets broadcasted by the PC are not seen by the Omap. I am using Wireshark on another PC to verify that the packets are being sent. Failure. I tried to change the Omap ip address (with ifconfig)... no luck. What am I missing? To complete the picture, when the Omap is in Scenario 2, if I run udhcpc ... it can communicate with the DHCP server and get an IP address. I also see the packets with Wireshark. So this means that the DHCP client is able to broadcast UDP packets. (Yes, I tried to use DHCP ports 67/68 but it doesn't work). I am using Boost C++ Asio UDP sockets. Specifically, I took the multicast examples and changed them to do broadcasting. Any help is appreciated. Thanks, Benedetto

  • How would the conversion of a custom CMS using a text-file-based database to Drupal be tackled?

    - by James Morris
    Just today I've started using Drupal for a site I'm designing/developing. For my own site http://jwm-art.net I wrote a user-unfriendly CMS in PHP. My brief experience with Drupal is making me want to convert from the CMS I wrote. A CMS whose sole method (other than comments) of automatically publishing content is by logging in via SSH and using NANO to create a plain text file in a format like so*: head<<END_HEAD title = Audio keywords= open,source,audio,sequencing,sampling,synthesis descr = Music, noise, and audio, created by James W. Morris. parent = home END_HEAD main<<END_MAIN text<<END_TEXT Digital music, noise, and audio made exclusively with @=xlink=http://www.linux-sound.org@:Linux Audio Software@_=@. END_TEXT image=gfb@--@;Accompanying image for penonpaper-c@right ilink=audio_2008 br= ilink=audio_2007 br= ilink=audio_2006 END_MAIN info=text<<END_TEXT I've been making PC based music since the early nineties - fortunately most of it only exists as tape recordings. END_TEXT ( http://jwm-art.net/dark.php?p=audio - There's just over 400 pages on there. ) *The jounal-entry form which takes some of the work out of it, has mysteriously broken. And it still required SSH access to copy the file to the main dat dir and to check I had actually remembered the format correctly and the code hadn't mis-formatted anything (which it always does). I don't want to drop all the old content (just some), but how much work would be involved in converting it, factoring into account I've been using Drupal for a day, have not written any PHP for a couple of years, and have zero knowledge of SQL? How might a team of developers tackle this? How do-able is it for one guy in his spare time?

  • Making REST request using LWP::Simple

    - by Alienfluid
    I am trying to use LWP::Simple to make a GET request to a REST service. Here's the simple code: use LWP::Simple; $uri = "http://api.stackoverflow.com/0.8/questions/tagged/php"; $jsonresponse= get $uri; print $jsonresponse; On my local machine, running Ubuntu 10.4, and Perl version 5.10.1: farhan@farhan-lnx:~$ perl --version This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi I can get the correct response and have it printed on the screen. E.g.: farhan@farhan-lnx:~$ head -10 output.txt { "total": 1000, "page": 1, "pagesize": 30, "questions": [ { "tags": [ "php", "arrays", "coding-style" (... snipped ...) But on my host's machine to which I SSH into, I get garbage printed on the screen for the same exact code. I am assuming it has something to do with the encoding, but the REST service does not return the character set type in the response, so how do I force LWP::Simple to use the correct encoding? Any ideas what may be going on here? Here's the version of Perl on my host's machine: [dredd]$ perl --version This is perl, v5.8.8 built for x86_64-linux-gnu-thread-multi
