  • Bash sourcing of functions in other languages

    - by ABach
    This is, perhaps, a silly question, but it's something that I've wondered about: is it possible to, say, define a Ruby/Python/Perl/etc. function in some file and then source it in Bash (to make it available anywhere in the current shell)? At the moment, I "source" scripts/functions in other languages by creating a bash alias that executes that script... But I wonder if it's possible for Bash to interpret those other functions directly? Thanks. :)

  • Is this scenario in compliance with GPLv3?

    - by Sean Kinsey
    For arguments sake, say that we create a web application , that depends on a GPLv3 licensed component, lets say Ext JS. Based on Section 0 of the license, the common notion is that the entire web application (the client side javascript) falls under the definition of a covered work: A “covered work” means either the unmodified Program or a work based on the Program. and that it will therefor have to be distributed under the same license Ok, so here comes the fun part: This is a short 'program' that is based on Ext JS var myPanel = new Ext.Panel(); The question that arises is: Have I now violated the GPL by not including the source of Ext JS and its license? Ok, so lets take another example <!doctype html> <html> <head> <title>my title</title> <script type="text/javascript" src="http://extjs.cachefly.net/ext-3.2.1/ext-all.js"> </script> <link rel="stylesheet" type="text/css" href="http://extjs.cachefly.net/ext-3.2.1/resources/css/ext-all.css" /> <script type="text/javascript"> var myPanel = new Ext.Panel(); </script> </head> <body> </body> </html> Have I now violated the terms of the GPL? The code conveyed by me to you is in a non-functional state - it will have to be combined with the actual source of Ext JS, which you(your browser) will have to retrieve, from a source made public by someone else to be usable. Now, if the answer to the above is no, how does me conveying this code in visible form differ from the 'invisible' form conveyed by my web server? As a side note, a very similar thing is done in Linux with many projects that depends on less permissive licenses - the user has to retrieve these on its own and make these available for the primary lib/executable. How is this not the same if the user is informed on beforehand that he (the browser) will have to retrieve the needed resources from a different source? Just to make it clear, I'm pro FLOSS, and I have also published a number of projects licensed under more permissive licenses. The reason I'm asking this is that I still haven't found anyone offering a definitive answer to this.

  • Support FOSS Projects via T-Shirts

    - by The MYYN
    Can we get a list of free and open source projects, which can be supported through purchasing branded garment? Free Software Foundation http://shop.fsf.org/ ps. I know this is extremly off-topic. But I'd like to buy clothing and support open source at the same time, if possible. And I'd like to know, where this is possible.

  • What are the most relevant OSS projects for .NET?

    - by Scott Hanselman
    Not a popularity contest, but if you were to elect some in some categories, what would be the names? Here are a few suggested categories. The only criteria I’d insist on would be: needs to be fully OSS, not a one-man show, have some people involved, have source available and with a well-know open source license (hopefully with no distinction between commercial and other uses) Blog engines Wikis Web frameworks WPF frameworks Silverlight frameworks Unit test frameworks (including spec?) ASP.Net tools more specialized frameworks Scott Hanselman and Hamilton Verissimo de Oliveira

  • Version Control System with API. Need to get metrics

    - by w1z
    Hi all, I have next situation. I need to choise source control system for my project. This scs must provide the API to my .net application to get information about check-in-s for specified user and date period and about changes which was done in this check-in-s (the number of added and updated lines). What source control system provides this functionality? P.S. I can't use the TFS, it's a limitation..

  • Is It Possible to Make Close Sourced PHP Product?

    - by Morgan Cheng
    I'm curious that whether all PHP product must be open sourced if it is to be deployed to other's web site. Since PHP code is executed by interpretation, if I have PHP product to be deployed on other's host, it seems no reason to prevent others view the source code. So, PHP product is destined to be open source, right?

  • compare a directory of files with an svn revision

    - by JoelFan
    If I have a directory of files (with subdirectories) that is not under source control (no .svn directories), is there any way to compare it with a revision in svn (i.e. "svn diff")? Similar question: if I have a directory of files that is under source control, can I do a diff with to a different URL than the one it was checked out from?

  • Are there any inherent benefits or drawbacks to choosing Google Code vs. SourceForge vs. Codeplex?

    - by kdmurray
    I've got a couple of different projects that I'd like to post up as open source. I've been trying to decide which of the three big open-source project hosting sites makes the most sense, or if I should just host it myself. Are there any inherent drawbacks or benefits to these three? Is there a "best" place to host a project? Do different sites make more sense for different kinds of projects?

  • OpenSource programming-languages in development?

    - by pile of junk
    I'm very interested in interpreter and compiler development and because I don't want to continue building mini compilers and interpreters I thought I could help some open-source project. Are there currently open-source projects on compilers/interpreters in early stages seeking developers? I mean yeah.. There won't be much to do for someone like me in Python, Ruby, and so on.

  • iPhone - Open excel from SSRS 2008

    - by milesmcgehee
    We're currently having a problem with our 2008 SSRS server sending excel reports to users with iPhones. They get the email with no problems, but when the XLS file is opened on the phone, it returns an error of: Invalid format. Everyone else can open the report with no problems (email/blackberry) The odd thing, is I can drag the file to my desktop from the message, open it, save it, and then email it again and it opens just fine on the phone. Does anyone know of hotfix that can be applied to the SSRS server to create the XLS files correctly? Or something I can change to make this work? I know we can send all the attachments in PDF but I'd like to keep them XLS if at all possible.

  • Adobe Illustrator can't open SVG file

    - by themapguyde
    I have a generated SVG file which for some reason won't open in Adobe Illustrator when I serve the file content from my ASP.net application, but if I were to write this generated file directly to the file system from my ASP.net application, the file opens fine! I've put a zip of the two files here: http://dl.dropbox.com/u/1761973/Files.zip The zip has two files: Map.svg Test.svg Map.svg doesn't open in Illustrator, it shows up a Text Import Options dialog, and upon clicking OK, will show the XML content of the file. Test.svg opens fine in Illustrator. Doing a comparison of the two files yields NO DIFFERENCES whatsoever! There must be something different in these two files (caused by downloading the generated SVG from the web browser), but I have no idea what?

  • How to know the source of certain TCP traffic on AIX

    - by A.Rashad
    We have two AIX boxes, one for production system and another for testing. both systems are running ATM machine switches, where the ATM device is connected via TCP socket. we had an issue on production system where the machine would power off or get disconnected but the netstat -na | grep <IP of machine > would still mention that the socket is up when simulated that case on the UAT environment, the problem did not happen, where the socket would terminate in 3 to 5 minutes. when sniffed on the traffic between the machine and ATM we found that no traffic takes place on production while there is some sort of heartbeat on UAT. but it is not initiated by the application. $>tcpdump | grep -v "10.2.2.71" | grep -v "HSRP" | grep "10.3.1.30" tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en6, link-type 1, capture size 96 bytes 09:08:13.323421 IP server073.afs3-callback > 10.3.1.30.impera: . 278204201:278204202(1) ack 3307884029 win 164 09:08:13.335334 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:08:23.425771 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:08:23.425789 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 09:09:13.628985 IP server073.afs3-callback > 10.3.1.30.impera: . 0:1(1) ack 1 win 164 09:09:13.633900 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:09:23.373634 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:09:23.373647 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 while on production, that traffic is not there. we want to know where this traffic is initiated from to implement on production to sense disconnection our comms parameters are: tcp_keepcnt = 2 tcp_keepidle = 100 tcp_keepinit = 150 tcp_keepintvl = 150 tcp_finwait2 = 1200 can anyone help? Editing Question: One point I missed because I was rushing to a meeting. the difference between the Production and UAT in setup is that in Production we have an application called F5 working as load balancer between the ATMs and the AIX box, while it is a direct connection through MPLS in case of UAT. note: we had one MPLS and one GPRS connected ATMs on UAT, and both connections terminated when unplugged in about 4 minutes Edit 2 the no -o tcp_timewait command returns 1 in both Production and UAT

  • Open source tomcat log viewer

    - by Ari
    I'm managing several tomcat instances (aprox 30-35) and looking for some console to centralize the logs. I tried php-syslog-ng before (no with tomcat), and found it useful. I would like that these software would have some of these features: -Syntax highlight according to the severity of the exceptions. -Tree view for stack traces and nested exceptions. Bonus point: -Alarm when certain pattern is matched.

  • Natively open .doc or .odt file in LaTex

    - by MaQleod
    I have looked at ways to convert word or open office text files to LaTex format, and those have been addressed on SU here and here. These will work, but I'd rather have a native single-step solution. Does anyone know of any module or add-on for LaTex that will let one open .doc and/or .odt files without the use of third-party conversion tools? It would be ideal if it would allow for editing and saving in the same format. If it makes any difference, I am using LaTex Editor in Windows.

  • Unable to run openoffice in headless mode

    - by uswaretech
    I want to automoate some PPT - PDF conversions, so I want to run openoffice in headless mode for scripting. On my machine with X running I can start opemoffice in headless mode via soffice -accept="socket,port=8100;urp;" -headless This doesn't seem to work on a server with X not running. $ soffice -accept="socket,port=8100;urp;" -headless /usr/lib/openoffice/program/soffice.bin X11 error: Can't open display: Set DISPLAY environment variable, use -display option or check permissions of your X-Server (See "man X" resp. "man xhost" for details) $ The error doesnt seem to make sense as well, as the point of specifying -headless was so that I do not need X, while this command seems to look for X.

  • Find the source of malware?

    - by Jud Stephenson
    I have a server that was running an older version of lighttpd (1.4.19 on a freebsd 6.2-RELEASE (yea, old) machine) and google alerted me that it had found malware embedded on one of my server's pages. It just so happened to be our index page. I promptly removed the malware and started looking at server logs for how it got there. With no trace in any of the logs of the files being edited, I noticed that the index page's owner had been changed to www, which is the lighttpd user. I then concluded that some sort of veunerability must have existed for that software version and promptly upgraded to 1.4.26. Now the malware is back. I have started some pretty verbose server logging with ftp, lighttpd, and all login attempts to try and see how this script is getting in. Are their any suggestions as to other approaches to take?

  • setting ulimit and ubuntu 8.04

    - by Wizzard
    Hi there, We have two ubuntu 8.04 servers. With the database server I set the table_cache to 1000 however when I restart mysql the status only shows 257 and the open files limit says 1024 I adjusted ulimit by doing ulimit -n 8192 and then restarting mysql; this seemed to do the tick however after a few hours I did ulimit -n and saw it had returned back to 1024 Bit of a worry. I edited the /etc/security/limits.conf and added mysql soft nofile 8192 mysql hard nofile 8192 then rebooted, no change. I then edited and change mysql to * rebooted, no change I then edited and changed it to one line * - nofile 8192 and rebooted, no change. cat /proc/sys/fs/file-max gives me 768730 sysctl fs.file-max gives me fs.file-max = 768730 I am at a bit of a loss to how I can set and keep the ulimit value set so I can increase the table cache properly on mysql.

  • Problems configuring DB2 CLI/ODBC System DSN ODBC Data Source Administrator

    - by Komyg
    I am trying to create a System DSN ODBC connection to a DB2 9.5 database, but I am getting a very strange problem. I've looked through the internet and found the following page that has some instructions on how I should proceed: http://www.ryslander.com/how-to-install-and-configure-db2-odbc-driver/. I followed these instructions and I am able to create a new System DSN, however when I try to configure it it seems as if my configurations don't work at all. For example, when I click on the "Configure" button on my System DSN and I add a TCP/IP protocol configuration on the "Advanced Settings" tab and click "Ok", no errors appear, but when I click on "Configure" again my TCP/IP setting has vanished. This happened to all my other configurations, such as database name, username, password etc. Could you help me figure out what I am doing wrong? Note: my user is in the administrator group and I am using a Windows Server 2008 R2 Enterprise x64. UPDATE I managed to create a User DSN and connect to the database. However the problem with the System DSN remains.

  • VNC over SSH on open Tunnel

    - by Joey Bagodonuts
    Is it possible to bind VNC server to a open SSH tunnel? I have a tablet that has initiated a reverse ssh tunnel to my server. This works fine over port 8080. I need to now bind to this port from my local machine. It looks like Ubuntu has some "remote desktop viewier" that has ssh built in capabilities so I assume the only thing I need to do now is figure out how to bind the tablets VNCserver to the open SSH tunnel. Is this possible? Thanks

  • Detecting source of memory usage on a Linux box

What's more, memory usage is growing all the time. I've had to restart my server once a week, because once my 256mb fills up it starts swapping, which it wouldn't do just for disk cache. Shouldn't there be some way for me to see the culprit?! I'm new to server admin, so please if there's something obvious I'm overlooking point it out to me.

So where do I look to see what is using all this memory?

  • TrueCrypt: Open volume without mounting

    - by Totomobile
    I have a corrupt TrueCrypt volume. When I try to mount it, the password is fine but I get an error: hdiutil attach failed no mountable file systems. I just need to open it without TrueCrypt trying to mount it too, so I can use that partition in a data recovery program. Also it's just an image file volume. I have read the documentation here: http://www.truecrypt.org/docs/?s=command-line-usage But I can't figure out which switch I need to use to only open an image and not mount it. I am using the Mac version, and I have set up an alias for the TrueCrypt shell command, so I can just type: truecrypt -t -v - ?? [][]..
