  - by wag2639

  What's a good C and GDK+ 2 integrated development environment (IDE) for developing in Ubuntu? Please state Pros and Cons for each suggestion. Notes: I'm used to using Visual C++ for Windows and C++ On Linux, I usually use gcc and vi (I'd want something friendlier than GDB) Thanks

• How it was detected if last ACK lost in TCP connection termination procedure?

  - by sonali

  In TCP Connection Termination, when client enters in TIME_WAIT state means the client waits for a period of time equal to double the maximum segment life (MSL) time, to ensure the ACK it sent was received. (I read above from a book computer networking by kurose and also given in following URL http://www.tcpipguide.com/free/t_TCPConnectionTermination-2.htm ) But how it was detected if last ACK(send by client as a response to server FIN) lost?

• How change the layout (e.g. background-color) of autoplaylists in foobar2000?

  - by UdeF

  A nice feature of the highly customizable music player foobar2000 is to generate autoplaylists. Autoplaylists are filtered lists of music that automatically update when you add new music to your collection. You would usually generate one by searching for something and saving it as new autoplaylists, e.g.: %added% DURING LAST 4 WEEKS %genre% HAS jazz OR %genre% HAS downtempo %date% GREATER 1949 AND %date% LESS 1970 Autoplaylist playlists are locked: You can't add or delete files. You can note that thanks to the little icon in the status bar at the bottom of your screen: foobar2000 let's you customize nearly everything, so here is my question: Is there a way to change the layout of the autoplaylists? For example i want to change the background-color in my playlist view. I use the Columns UI component.

• Does frequently formatting and reinstalling an operating system damage a hard drive?

  - by Closure Cowboy

  I tend to format and reinstall my operating system fairly frequently (about once a month). I apologize for my lack of technical terms, but I do not perform a "full format" (the type of formatting that zeros-out the existing data). Regardless, I know that most modern operating systems consume several GBs of data. Is doing this particular damaging to my hard drives? Would it matter whether I'm using a solid state drive (I'm not)?

• Very Dark Windows 7 Screen

  - by user147521

  My Gateway laptop -Windows 7- screen became too dark a few days ago after I finished installing Windows automatic update. I can see nothing unless I use a flashlight. Windows login screen is the only bright screen for few seconds. What should I do to resolve this issue? I checked power-saving/ Power Options settings and rebooting in Safe Mode. I tried to lower the refresh rate but it did not allow me. The laptop adapter type is ATI Radeon Xpress series. I calibrated display color. I uninstalled and reinstalled the adapter. I tried to update the driver but the driver is up to-date. Any help would be appreciated.

• Tcp Port Open by Unknown Service

  - by Singularity

  Running openSUSE 11.2 x86_64. Here's what a nmap of my IP provides: PORT STATE SERVICE 23/tcp open telnet 80/tcp open http 2800/tcp open unknown 8008/tcp open http I would like to know How to view What service is causing Port 2800 to be opened? A few search engine results led me to believe that it is supposedly a port opened by a Trojan called "Theef". If it is indeed a Trojan, what can be done to weed it out? Is my desktop's security compromised?

• Other processes take over port 80 when restarting Apache - why, and how to solve?

  - by user72149

  I have a CentOS 5.5 server running Apache on port 80 as well as some other applications. All works fine until I for some reason need to restart the httpd process. Doing so returns: sudo /etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs First I thought perhaps httpd had frozen and was still running, but that was not the case. So I ran netstat to find out what was using port 80: sudo netstat -tlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:7203 *:* LISTEN 24012/java tcp 0 0 localhost.localdomain:smux *:* LISTEN 3547/snmpd tcp 0 0 *:mysql *:* LISTEN 21966/mysqld tcp 0 0 *:ssh *:* LISTEN 3562/sshd tcp 0 0 *:http *:* LISTEN 3780/python26 Turns out that my python process had taken over listening to http in the instant that httpd was restarting. So, I killed python and tried starting httpd again - but ran into the same error. Netstat again: sudo netstat -tlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:7203 *:* LISTEN 24012/java tcp 0 0 localhost.localdomain:smux *:* LISTEN 3547/snmpd tcp 0 0 *:mysql *:* LISTEN 21966/mysqld tcp 0 0 *:ssh *:* LISTEN 3562/sshd tcp 0 0 *:http *:* LISTEN 24012/java Now my java process had taken over listening to http. I killed that too and could then successfully restart httpd. But this is a terrible workaround. Why will these python and java processes start listening to port 80 as soon as httpd is restarted? How to solve? Two other comments. 1) Both java and python processes are started by apache from a php script. But when apache is restarted, they should not be affected. And 2) I have the same setup on two other machines running Ubuntu and there's no problem there. Any ideas? Edit: The Java process listens to port 7203 and the python process supposedly doesn't listen to any port. For some reason, they start listening to port 80 when apache is restarted. This hasn't happened before. On Ubuntu it runs fine. For some reason, on my current CentOS 5.5 machine, this problem arises.

• Any way to disable specific CPU idle (Cx) states?

  - by Philippe

  I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy. FYI: I'm running Windows 7 64-bit

• Monitor does not turn on until reset

  - by eggonlegs

  I have a system with an ATI 4870 hooked up to a Samsung P2350 using DVI. My motherboard is a GA-EP45 DS4P with the latest BIOS. The situation is: I turn on my PC (with the power switch) I get a blank screen I hit reset and the PC boots up normally, i.e. the monitor turns on and This has been the case for a couple of months (Was away for a while, came back and it was the same case). I was hoping the situation would somehow fix itself but alas, nothing. I have tried numerous settings in the BIOS (Combinations of different settings of the ACPI and power saving options) and have tried different cables. Has anyone experienced this before? I don't know where to go from here. It is pretty infuriating because it means I can't put my computer to sleep, as the monitor won't come on. Any help is appreciated. Thanks

• Will any USB DVD reader work with Apple Mac's?

  - by Kev

  Following on from this question: Can Apple Macintosh computers boot from a USB volume? Can I use any USB 2.0 DVD drive to boot a Mac from? I had a look around my local PC World today and only the more expensive drives explicitly state on the packaging that they were Mac compatible. Is this just because these products have been through Apple's hardware approval/testing programme, or do Mac's have some special requirement?

• Requisite of file.append

  - by Jeff Strunk

  Is it possible to make salt require that a particular file was appended to as opposed to the file merely existing? It seems like I can only require a file state. The source looks like it strips out any method names from a require attribute. In the example below, I only want the foo service to run if my lines have been appended to /etc/security/limits.conf. file.append: - name: /etc/security/limits.conf - text: - root hard nofile 65535 - root soft nofile 65535 foo: service.running: - enable: True - require: - file.append: /etc/security/limits.conf

• Is there a proper way to clear logs?

  - by John H.

  I was wondering if there was a proper way to clear logs in general? I'm new to Ubuntu and I'm trying to set up Postfix. The log in question is /var/log/mail.log. I was wondering if there was a correct way to clear it, rather than me going in it and deleting all the lines and saving it. I find that sometimes errors don't get written to it immediately after I clear the log and save it. Side note: I'm having trouble setting up Postfix and am trying to make it easier for me to read the logs hoping it can help me out, instead of having to scroll all the way down.

• VirtualBox Shared Folder encoding issue

  - by Somebody

  I'm using Ubuntu in Virtualbox and have a shared folder mounted to Virtualbox which i'm accessing inside Ubuntu. The problem is, that when i'm editing and saving some files from shared folder in Windows it's getting some strange symbols at the end of edited file. There must be some encoding issues. Doesn't Virtualbox automatically converts files to Unix standards? To fix that, i have to re-mount shared folder inside Ubuntu each time i'm editing some file. Any solution to avoid re-mounting each time I edit? I'm mounting like that: mount -t vboxsf SVN /opt/htdocs/ Thanks.

• How to make one CPU to be used simulataneously be three different users

  - by beginning_steps

  As a bootstrapping start-up we are thinking of saving on the IT hardware cost by making more use of the hardware that we have. As a solopreneur I have a laptop config : intel core2duo processor, 3Gb RAM and 250 GB RAM. Now we are planning to increase our team to 3 members. Will like your suggestions on the nest cost-effective step that I can take so that I can use the computing power of the existing laptop to act as a kind of server and then buy to more monitors where the new recruits can do the daily work on and they need to have different login id and access and they dont need access to all the files/applications as are available in my laptop. We use internet intensively to do our day to day activity. Please share you experience, whether you think this is a good ploy or there is any other more effective way of achieving the same result.

• Hardware advice for bitmap / openGL image processing server?

  - by pdizz

  I am trying to work out a build for a processing server to handle bitmap processing as well as openGL rendering for chroma-keying images and Photoshop automation. My searches here and on Google have turned up surprisingly few results, and seeing that there aren't tags for bitmap or image processing I take it this is a specialized application. The bitmap processing is very cpu-intensive while the chroma-keying and Photoshop stuff is gpu-intensive. I doubt this is a case of over-optimization as our company batches thousands of images a day (currently on individual workstations) and any saving in processing time and workstation down-time would be beneficial. Does anyone have any experience with this type of processing server? Any special considerations that would go into a build like this or am I over-thinking it?

• Macro to copy values to new sheet and prompt user where they want to save

  - by MasterJedi

  I'm looking to create a macro in Excel 2007 which will do the following: copy the formatting and values from a sheet called 'report', insert this into a new workbook, naming the file with the value in 'B9' and appending the word 'report' to this when copying the data into a new workbook, the formatting of the original should be retained, but cell contents pasted as values rather than formulas prior to saving the file with the above name, the user will be prompted to choose their folder at the end, a message will be displayed alerting the user that the file has been saved successfully Any assistance would be much appreciated. Thanks. I have attempted to do this, but my experience with VBA is limited. Here is what I have done so far... Application.DisplayAlerts = False Worksheets("Report").Copy With ActiveSheet.UsedRange .Value = .Value End With ActiveSheet.DrawingObjects.Delete Set wbNew = ActiveWorkbook wbNew.SaveAs Application.GetSaveAsFilename wbNew.Close True Application.DisplayAlerts = True

  I use TextMate on Mac OS X to develop. The files I need to edit are on a Linux machine, and I have the Linux filesystem mounted on my Mac OS X. Opening the files and saving them in TextMate is not a problem. What I want to do (from my Mac OS X) is be able to... SSH <linux> cd <folder> mate <filename> I want that to open up the file in TextMate on my Mac OS X (thus, shifting focus from my Terminal.app to TextMate.app). How can I achieve this effect?

• FTP client hangs after a while

  - by lfbn

  I'm using Linux Ubuntu 12.04 with curlftpfs to connect to a remote server. After mounting a remote ftp, opening and saving files with vim, list directories and files, for some time, after a while (no more of 30 minutes), with no reason it hangs. After opening other terminal tabs, all tabs remain iddle...but when using filezilla without restart the computer I still can get to the server and working with no problem. When using Nautilus, instead of curlftpfs, I'm having the same problem. After a while it hangs. Can anyone help me please?

• Registry changes not being preserved (unwanted restore)

  - by W Hofmeyr

  Changes made to system or program settings which are stored in the registry are restored to a previous values after a reboot. This question was also posted Each time I do restart - Windows 8 resets my settings/registry to some state The "solution" was to create a new user - this is not an option as the user is defined by the domain server. Does anyone know what is causing the resetting and what a proper solution is?

• Is WAMP installed to use mod_php?

  Really simple question, I'm completely confused about whether the 'default' state for php to run in is as a part of apache, until today I thought php was a separate program which apache communicated with. So is WAMP installed as mod_php?
