• Installed geany has no options

  - by arundex

  I'm new to geany IDE. I installed geany from ubuntu software centre, and the window has no options other than opening a new file. I can't file any preference, tools option too for configuring. I heard it is a full fledged IDE. Also, from the screenshots available from the software center, it seems my Geany installation is missing almost everything. I'm not able to post the screenshots, but my interface just has 3 buttons. create a new file, open an existing file and a quit button. Everything else is inactive. I accidentally closed the sidepane, and I can't find any options to bring back that too. EDIT What am I missing in my Geany installation? PS: I tried installing from source from geany website. But, it posted some error saying GTK files not found. But, I removed geany from software centre and reinstalled several times. It installed Geany without problems, but with afore mentioned problems, that is I have nothing in my interface. Also, even after reinstalling, somehow Geany remembers to hide the sidepane by default, which I'm not able to see at all. I also added Geany ppa repository manually for latest fixes, but still when I reinstall from software centre I get a plain blank Geany interface. Thanks.

• What makes Ubuntu awesome [closed]

  - by Shagun

  My question may sound stupid or inappropriate for this site in which case I apologize before hand. This thing has bothered me for quiet some time so please correct me if there is anything inappropriate: I have been using Ubuntu for past 1 year and I know how awesome it is and in what terms is it better than windows.But around 2 weeks ago some of my friends asked me to show them something on Ubuntu or tell something about Ubuntu that makes people prefer it over windows. I tried to convince them by telling things like its open-source, that most of the super-computers run on Linux, that its unaffected by virus and other stuff but they seemed unconvinced. Maybe what they we looking for was some mind-boggling feature which only Ubuntu (Linux) has. Since that day I have been thinking but yet don't have anything that will show them the true powers of Linux. Please suggest your response to such a situation as it troubles me that I am not able to explain them one thing that I myself believe in. Thank you. PS : I am not looking for a theoretical answer but would like to hear of one such application which it and only it provides.

• Central Storage for windows user accounts homedirs .. hardware/software needed?

  - by mtkoan

  We have ~120+ users in our network, and are endeavoring to centralize logon authentication and home directory storage server-side. Most of the users are Windows 2000/XP machines, and a few running Mac OS X. Ideally the solution will be open-source-- can this all be managed from a Linux server running LDAP and Samba? Or would a hacked-NAS Box with a FreeNAS or similar suffice? Or is Micro$oft's Active Directory really the preference here. Is it viable to store PST files on this server for users to read from and write to? They are very large ~1.5gb. We have no mail server (or money) capable of Exchange or IMAP, only an old POP3. What kind of hardware horsepower and network architecture should we have for this kind of thing?

• C#.NET: How to update multiple .NET pages when a particular event occurs in one .Net page? In another words how to use Observer pattern(Publish and subscribe to events)

  Problem: Suppose you have a scenario in which you have to update multiple pages when an event occurs in main page. For example imagine you have a main page where you are dispalying a tab control. This tab control has 3 tab pages where you are loading 3 different user controls. On click of an update button in main page imagine if you have do something in all the 3 tab panels. In other words an event in main page has to be handled in many other pages. An event in main page which contains the tab control has to be handled in all the tab panels(user controls) Answer: Use Observer pattern Define a base page for the page that contains the tab control. Main page which contains the tab: Baseline_Baseline Basepage for the above main page: BaselineBasePage User control that has to be udpated for an event in main page: Baseline_PriorNonDeloitte Source Code: public class BaselineBasePage : System.Web.UI.Page { IList lstControls = new List(); public void Add(IObserver userControl) { lstControls.Add(userControl); } public void Remove(IObserver userControl) { lstControls.Remove(userControl); } public void RemoveAllUserControls() { lstControls.Clear(); } public void Update(SaveEventArgs e) { foreach (IObserver LobjControl in lstControls) { LobjControl.Save(e); } } } public interface IObserver { void Update(SaveEventArgs e); } public partial class Baseline_Baseline : BaselineBasePage { . . . this.Add(_ucPI); this.Add(_ucPI1); protected void abActionBar_saveClicked(object sender, EventArgs e) { SaveEventArgs se = new SaveEventArgs(); se.TabType = (BaselineTabType)tcBaseline.ActiveTabIndex; this.Update(se); } } Public class Baseline_PriorNonDeloitte : System.Web.UI.UserControl,IObserver { public void Update(SaveEventArgs e) { } } More info at: http://www.dofactory.com/Patterns/PatternObserver.aspx span.fullpost {display:none;}

• Windows 7 Desktop slideshow

  - by blackmastiff

  I have my windows 7 (Home Professional if it matters) set to automatically change the background every 20 minutes with the source of the slideshow as a folder in the Pictures library. Recently, the slideshow has not been functioning. The pictures do not change while the computer is on; they only seem to change when it is shut down (i.e. there is a different desktop on each boot), or about 50% of the time when waking the computer from hibernation. I've changed the time settings, the folder location on the drive, and made sure to disable all programs that tweak the desktop with no luck. Any thoughts?

• Looking for a product configurator

  - by Netsrac

  I am looking for a product configurator for products with high complexity. The main goal is to allow a sales person to configure the product in a correct and working manner. The product is a combination of hard- and software options. The options for sure have dependecies (so option A needs B and C) and can also exclude each other. The performance requirements of the software related to the hardware need to be considered. So some rules need to be defineable. Does anybody know a tool (preferred open source) doing that job? Thanks for your help.

• Will learning to use Fedora also teach me my way around Redhat (CentOS)?

  - by Matt Untsaiyi

  I want to dive into the open source world and start using a Linux distro while learning to program. I've looked over the options and it pretty much boils down to Fedora or CentOS. The reasoning behind it is I'm hoping to kill two birds with one stone... Redhat seems to be "the choice" for servers, so I figure as I learn to program, I can also learn my way around Linux... or Redhat more specifically... and get that under my belt too. I want to use Fedora, and be on the frontier of new software (since I'm not doing anything critical), but if it's completely different than Redhat I'd rather just use CentOS. So is it? Or can I use one and know the other?

• Why my Firefox displays XML files as blank pages?

  - by n1313

  Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons, but the problem was not solved. All other browsers (Chrome, Opera) render the same file as an XML tree. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please?

• Twisted pair cable twists and unwanted signals issue

  - by ziaharipur

  I am confused about one point I have read the following paragraph from the networking book. “the twists in the twisted pair cable are used to avoid the unwanted signals. For example one twist, one wire is closer to the noise source and the other is farther; in the next twist the reverse is true. Twisting makes its probable that both wires are equally affected by the unwanted signal. This means that the receiver which calculate the difference between the two receives no unwanted signal.” Now ok I understood the purpose of twists but I am confused about how receiver will calculate the difference when it will receive the signal?. How unwanted signal will be eliminated ? Another thing that I want to make clear is , I am beginner please provide such an answer that can be understood.

• Live HTML Preview

  - by netbeanstips

  When you need to edit an HTML document in NetBeans you may find useful this little plugin that adds a Preview tab to HTML editor window. The plugin works with some small issues in NetBeans 7.4 but I recommend using development builds instead. So install the plugin, restart NetBeans and open any HTML document. Notice there's a Preview button in editor's toolbar (see the red rectangle in the picture below). Now split the editor window by dragging the split button at top right corner. You can also use menu View - Split - Vertically.  Then in the bottom split part toggle Preview button. You will get a live preview of your HTML source code. The preview pane will auto-refresh as you edit the HTML code. There are even some handy tools in Preview toolbar, for example you can resize the preview browser to match the screen dimensions of various device types. I know there is full-blown HTML5 support in NetBeans 7.4. But if you need to edit a single document or when you're running Java-only NetBeans distribution this plugin may come handy... Note: The plugin is built on top of embedded WebKit browser which is based on JavaFX WebView component. So there might be some issue when using the plugin on some flavors of Linux.

• How can I find a computer on my network that is doing mass mailings?

  - by Alex Ciarlill

  I was notified by my isp that one of my machines is sending out spam. This happened about 3 months ago on windows machine running cygwin that was hacked due to an SSH vuln. The hackers setup IIS and SMTP. I cleared out the machine and all the services are disabled so I think that machine is okay I am wondering if there is any other way to identify which machine it could be coming from? The ISP has NO useful information such as source port, destination port, destination IP... nothing. I am running DD-WRT on my router, Windows 7 PC and a Windows XP PC.

• iTunes for Ubuntu Studio

  - by soundblastdj

  I have finally gotten my old Mac HDD sorted out, and now I would like to know if anybody has either: a) a way to run iTunes without wine, as it did not work out well for me the last time I tried it, or b) any other media player that will sync with an iPod and, more importantly, use the same file system. When my Mac died, I started to get into open source. I bought a MacBook Air, only out of necessity. For almost two years now, I have not once backed up or synced my iPod. I am getting nervous that it may give up on it's life soon and would like to find a solution. I don't have enough room on my Air, and it would just erase my iPod anyway... Another thing that I am having trouble with is the way iTunes arranged the music. Now, it is arranged all by artist, then album, the song and I would like to have a media library, but somewhere around 400GB of music is a lot to sift through (I have attempted in the past). Thus I am looking for something that will use the same library format. A side note: As I was writing this I started to wonder; Is a Hackintosh in order here? If somebody will give me instructions on how to install MacOSX for free (maybe Mavericks?) in a dual boot with Ubuntu, I will be ever grateful. :) Thanks, soundblastdj

• Wireshark TCP Window Size Value

  - by T Vernon

  I am debugging an application with Wireshark and watching the TCP Window Size value shrink on one side of the communication. If the packet's TCP section shows a "Window size value: 1", does that mean the source's window size is 1 or the destination's window size is 1? I know one side is communicating faster than the other can handle, I just want be sure I know which one it is. 1 192.168.0.1 - 192.168.0.100, Modbus/TCP, Length: 66, Window Size Value: 1 2 192.168.0.100 - 192.168.0.1, TCP, Length: 60, Window Size Value: 92 3 192.168.0.100 - 192.168.0.1 TCP, Length: 310, Window Size Value: 92 4 192.168.0.1 - 192.168.0.100 TCP, Length: 54, Window Size Value: 0 So is 192.168.0.1's window size 0 or is it reporting that 192.168.0.100's window is 0? Thanks.

• Automated monitoring of a remote system that sends email alerts.

  - by user23105

  I need to monitor a remote system where the only access I have is that I can subscribe to email alerts of completed/failed jobs. I would like a system that can monitor these emails and provide an SMS or other alert when: An email indicates failure. A process that was expected to complete by a given time has not. A process that was expected to complete N minutes after completion of another process has not completed. Are there any existing tools that allow this? I'd consider any option - SaaS, open-source, COTS, as long as I don't have to write it myself! Cheers, Blake

• websites resolving in browser but not resolving in CLI. Can ping IP but not domain name (unknown host)

  - by tjkoding

  Hi guys I'm currently developing using rails and for some reason bundle install is returning the following output Error Bundler::HTTPError during request to dependency API Fetching full source index from https://rubygems.org/ Could not reach https://rubygems.org/ I've discovered that pinging by domain name keeps returning an unknown host. The browser is still resolving web pages just fine and I've managed to confirm that the problem is localized (i.e. the rubygems page isn't down). I'm completely lost so any help would be much appreciated. Thanks in advance!

• Command-line tool to search for file names on offline backup drives

  - by halloleo

  I am looking for an open-source (command-line) tool to register and search all my (backup) drives on a file name level. I want to search for file and folder names preferably written as regular expressions or file glob patterns. The external drives contain just normal HFS and NTFS filesystems. The backups are done via direct file copy. Requirement is that the tool compiles on OS X and works without each of the drives attached, but rather pointing me to the drive in case a drive contains a file with the pattern I searched for. At the moment I use a hand-knit script solution with locate databases, one for each external backup drive, but this is rather cumbersome, because locate itself can accesses only one database at a time and does not contain any management system for all the indices/databases. Are there any other tools out there for this?

• Crunchbang asks for URIs to get build dependencies for php5 [closed]

  - by Koen027

  I'm trying to install PHP5, by compiling it myself. I'm doing this on Crunchbang Linux, version 11. Specifically, the version using the 3.2 kernel. Crunchbang 11 is based on Debian. This is a 64-bit Virtual machine, running on a 64-bit Win7 Professional. Using Virtualbox 4.2 This is my sources.list file: http://pastebin.com/rQJNwX7c When I try to do sudo apt-get build-dep php5, I get the following output: Reading package lists... Done Building dependency tree Reading state information... Done E: You must put some 'source' URIs in your sources.list I'm not sure what's going on here. Can anyone point out what's missing in my setup? Also, since I'm under 300 reputation on serverfault, I can't add the "crunchbang" tag.

• Recommend a desktop app to monitor port 80 on servers

  - by busyone

  Hello, I did some googling but was unsuccessful, so I am posting here. I am looking to get an app (preferably free/open source) to monitor my servers on port 80 that would send me an email/text when some predefined timeout triggers. I could probably write something in VB to do this but i am burried with projects, why reinvent the wheel. I know there are services out there that want you to pay $5/month to do so, I was thinking about a Windows app that would sit on my computer and simply monitor predefined list of IPs on port 80. Thanks!

• What is the most effective approach to learn an unfamiliar complex program? [closed]

  - by bdroc

  Possible Duplicate: How do you dive into large code bases? I have quite a bit of experience with different programming languages and writing small and functional programs for a variety of purposes. My coding skills aren't what I have a problem with. In fact, I've written a decent web application from scratch for my startup. However, I have trouble jumping into unfamiliar applications. What's the most effective way to approach learning a new program's structure and/or architecture so that I can start attacking the code effectively? Are there useful tools for their respective languages (Python and Java are my two primary languages)? Should I be starting with just looking at function names or documentation? How do you veterans approach this problem? I find this has to be with minimal help from coworkers or contributors who are already familiar with the application and have better things to do than help me. I'd love to practice this skill in an open source project so any suggestions for starting points (maybe mildly complex) would be great too!

• Autojump in 12.04 doesn't work

  - by hnasarat

  https://launchpad.net/ubuntu/+source/autojump I installed with apt-get, checked out the man page and added . /usr/share/autojump/autojump.sh to my .bashrc, like it says. When I cd around the filesystem, nothing gets added to ~/.local/share/autojump. I then tried adding . /usr/share/autojump/autojump.bash, but that didn't work either. autojump -a ~/Dropbox properly creates a file ~/.local/share/autojump/autojump.txt, but running j Drop < TAB > doesn't autocomplete to j ~/Dropbox/ as it should. However, j < TAB > does autocomplete to j ~/Dropbox. I know my bash-completion is working since it works for git, dd, and others. I know there's a newer version in the repositories set for Quantal. Perhaps that would work? I don't know how to install that version though. I've used autojump with mac homebrew (and it installed without any issue), so I know there is missing functionality. In general I'm really annoyed that I can't get this working...I've spent hours on it! Needless to say, help would be very appreciated.

• Phishing attack stuck with jsp loginAction.do page? [closed]

  - by user970533

  I 'm testing a phishing website on a staged replica of an jsp web-application. I'm doing the usual attack which involves changing the post and action field of source code to divert to my own written jsp script capture the logins and redirect the victim to the original website. It looks easy but trust me its has been me more then 2 weeks I cannot write the logins to the text file. I have tested the jsp page on my local wamp server it works fine. In staged when I click on the ok button for user/password field I'm taken to loginAction.do script. I checked this using tamper data add on on firefox. The only way I was able to make my script run was to use burp proxy intercept the request and change action parameter to refer my uploaded script. I want to know what does an loginAction.do? I have googled it - its quite common to see it in jsp application. I have checked the code; there is nothing that tells me why the page always point to the .do script instead of mine. Is there some kind of redirection in tomcat configuration. I like to know. I'm unable to exploit this attack vector? I need the community help

• Transient mysqlcheck errors about "size of datafile" (file too small)

  - by Adam Backstrom

  Running mysqlcheck on a live database is giving me transient errors like this one: mydatabase.mytable error : Size of datafile is: 500719688 Should be: 501000484 error : Corrupt When I run the command again or check the table one-off using mysql, it's listed as OK. Is this just a side effect of running checks on live tables? Is it possible that data is not flushed, hence the strange discrepancy? We moved several databases this morning by shutting down mysqld on the source and rsyncing files across to the new server, but these are all MyISAM tables so I don't believe the two things are related. (But I mention it just in case.)
