• How to change the screen resolution in VNC viewer for Ubuntu 12.04 without a monitor?

  - by user325320

  I have Ubuntu 12.04 installed on a machine and I always use it remotely from VNC. When I have monitor connected to this machine, I can change the resolution of my VNC viewer in the following line: $vnc4server --geometry 1440x900 This worked for me, but I always use this machine remotely, I unplug the monitor and reboot. and the above command line not work anymore. Then I tried xrandr SZ: Pixels Physical Refresh *0 1024 x 768 ( 260mm x 195mm ) *60 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none There is only one option available, so I tried to add a new one. $cvt 1440 900 # 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync $xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync $xrandr --addmode S2 "1440x900_60.00" then I checked with xrandr again and can't see the new mode added. I try to execute the following command and get error says my RandR is too old. $xrandr --output S2 --mode 1440x900_60.00 xrandr: Server RandR version before 1.2 but this does not make sense to me, if I plug in the monitor back and run the xrandr command, it works again! It seems that Ubuntu must conntect to a real monitor before I can change my resolution in my VNC viewer. Can anyone help? UPDATE: Finally I solved this problem by changing to tightvncserver $tightvncserver -geometry 1440x900 works for me. Thanks everything answered my question

• Entity System with C++

  - by Dono

  I'm working on a game engine using the Entity System and I have some questions. How I see Entity System : Components : A class with attributs, set and get. Sprite Physicbody SpaceShip ... System : A class with a list of components. (Component logic) EntityManager Renderer Input Camera ... Entity : Just a empty class with a list of components. What I've done : Currently, I've got a program who allow me to do that : // Create a new entity/ Entity* entity = game.createEntity(); // Add some components. entity->addComponent( new TransformableComponent() ) ->setPosition( 15, 50 ) ->setRotation( 90 ) ->addComponent( new PhysicComponent() ) ->setMass( 70 ) ->addComponent( new SpriteComponent() ) ->setTexture( "name.png" ) ->addToSystem( new RendererSystem() ); My questions Did the system stock a list of components or a list of entities ? In the case where I stock a list of entities, I need to get the component of this entities on each frame, that's probably heavy isn't it ? Did the system stock a list of components or a list of entities ? In the case where I stock a list of entities, I need to get the component of this entities on each frame, that's probably heavy isn't it ?

• Cool SQL formatter tool

  - by AndyScott

  I have to deal with all types of code that was written by people from different organizations, different countries, using different languages, obviously standards are different across these sources.  One of the biggest headaches that I ahve come across is how people differ in the formatting of their SQL statements, specifically stored procs.  When you regularly get over 500 lines in a sproc, if the code is not formatted correctly, you can get lost trying to figure out where one nested BEGIN begins, and another nested END ends.  One of my co-workers showed me this site today that does a pretty damn good job of making sense of that type of code: http://www.dpriver.com/pp/sqlformat.htm.   This is a free website that offers a box to enter your nasty code, and click "Format SQL" and have it clean it for you.  I am sure that there are situations where this may not work, but given the code that I have been working with recently, it does a really good job.  There is a pay version with more options, including VS add-in, desktop component (with quickkeys to clean text in programs like notepad), the ability to output in HTML, and other stuff.  Heck, I watched a demo where the purchased version will take formatted SQL code and turn it into a generic Stringbuilder object embedded in a formatted. Yes, this seems like a shameless plug, but no, I have no relation/knowledge of anyone involved in the development of this product, it just seems useful.  Either way, I recommend checking out the free version.

• Code Trivia #4

  - by João Angelo

  Got the inspiration for this one in a recent stackoverflow question. What should the following code output and why? class Program { class Author { public string FirstName { get; set; } public string LastName { get; set; } public override string ToString() { return LastName + ", " + FirstName; } } static void Main() { Author[] authors = new[] { new Author { FirstName = "John", LastName = "Doe" }, new Author { FirstName = "Jane", LastName="Doe" } }; var line1 = String.Format("Authors: {0} and {1}", authors); Console.WriteLine(line1); string[] serial = new string[] { "AG27H", "6GHW9" }; var line2 = String.Format("Serial: {0}-{1}", serial); Console.WriteLine(line2); int[] version = new int[] { 1, 0 }; var line3 = String.Format("Version: {0}.{1}", version); Console.WriteLine(line3); } } Update: The code will print the first two lines // Authors: Doe, John and Doe, Jane // Serial: AG27H-6GHW9 and then throw an exception on the third call to String.Format because array covariance is not supported in value types. Given this the third call of String.Format will not resolve to String.Format(string, params object[]), like the previous two, but to String.Format(string, object) which fails to provide the second argument for the specified format and will then cause the exception.

• Apache hanging with MaxClients is reached

  - by Ash White

  My Apache 2.2 (preform MPM) is hanging when MaxClients is reached, rather than queueing up requests and serving them when child processes become free. When this happens, the web server is totally unresponsive until it is manually restarted. The server stack is Ubuntu 8, MySQL 5, PHP 5. Hardware is Dual Xeons (2.8) with 2GB of RAM. It serves 30,000 - 50,000 pageviews per day. Static images, CSS, and JS are offloaded to a separate server and PHP is cached using eAccelerator. The HTML output of many pages is cached to the filesystem. Relevant Apache directives: KeepAlive On MaxKeepAliveRequests 50 KeepAliveTimeout 2 StartServers 2 MaxClients 150 MinSpareThreads 25 MaxSpareThreads 75 ThreadsPerChild 25 MaxRequestsPerChild 2000

• 11gr2 DataGuard: Restarting DUPLICATE After a Failure

  - by rene.kundersma

  One of the great new features that comes in very handy when databases get larger and larger these days is RMAN's capability to duplicate from an active database and even restart a duplicate when it fails. Imagine yourself the problem I had lately; I used the duplicate from active database feature and had to wait for an hour or 6 before all datafiles where transferred.At the end of the process some error occurred because of the syntax. While this error was easily to solve I was afraid I had to redo the complete procedure and transfer the 2.5 TB again. Well, 11gr2 RMAN surprised when I re-ran my command with the following output: Using previous duplicated file +DATA/fin2prod/datafile/users.2968.719237649 for datafile 12 with checkpoint SCN of 183289288148 Using previous duplicated file +DATA/fin2prod/datafile/users.2703.719237975 for datafile 13 with checkpoint SCN of 183289295823 Above I only show a small snippet, but what happend is that RMAN smartly skipped all files that where already transferred ! The documentation says this: RMAN automatically optimizes a DUPLICATE command that is a repeat of a previously failed DUPLICATE command. The repeat DUPLICATE command notices which datafiles were successfully copied earlier and does not copy them again. This applies to all forms of duplication, whether they are backup-based (with and without a target connection) or active database duplication. The automatic optimization of the DUPLICATE command can be especially useful when a failure occurs during the duplication of very large databases. If a DUPLICATE operation fails, you need only run the DUPLICATE again, using the same parameters contained in the original DUPLICATE command. Please see chapter 23 of the 11g Release 2 Database Backup and Recovery User's Guide for more details. B.w.t. be very careful with the duplicate command. A small mistake in one of the 'convert' parameters can potentially overwrite your target's controlfile without prompting ! Rene Kundersma Technical Architect Oracle Technology Services

• Slower wireless speed in Ubuntu 12.04 (64-bit) on Asus USB-N13

  - by PhantonTurtle

  I have an Asus USB-N13 which I use for wireless internet on my desktop. The download speed I get on Windows 7 (dual-boot) is 15.22 Mbps. On Ubuntu 12.04 (64-bit) I can only get 1.09 Mbps. I asked a question about this on the Ubuntu forums as well, but I did not get an answer. Here is the output from lsmod | grep rt which gives me, parport_pc 32866 0 rtl8192cu 103297 0 rtl8192c_common 75767 1 rtl8192cu rtlwifi 111202 1 rtl8192cu mac80211 506816 3 rtl8192cu,rtl8192c_common,rtlwifi cfg80211 205544 2 rtlwifi,mac80211 parport 46562 3 parport_pc,ppdev,lp I installed the drivers from Realtek (my chipset is Realtek, not Ralink) but that did not work.

• Laptop battery: is voltage really important to respect?

  - by Marc-Andre R.

  I got an Acer Aspire 5100 and I just bought a new battery (after the stock battery just died yesterday). But I saw something after buying and I'm wondering whether it's really important or not. My stock battery was a 6-cell 4000mah 11.1v and the new battery is an 8-cell 4800mah 14.8v . I know that 8-cell and 4800mah is okay, but what about the 14.8v instead of 11.1v? The battery description says it's compatible with my laptop model (AS5100, model BL51), but the voltage difference makes me wonder. Will the laptop only take what it needs? Or will it be getting 14.8v straight in the brain? I know that my wall plug claims to output 19v, so logically I'm thinking a higher voltage battery shouldn't be a problem. Am I correct in thinking this? Thanks in advance for your answers!

• It&rsquo;s About You: Tell Microsoft How They&rsquo;re Doing!

  - by juanlarios

  Every fall and spring, a survey goes out to a few hundred thousand IT folk in Canada asking what they think of Microsoft as a company. The information they get from this survey helps them understand what problems and issues you’re facing and how they can do better. The team at Microsoft Canada takes the input they get from this survey very seriously. Now I don’t know who of you will get the survey and who won’t but if you do find an email in your inbox from "Microsoft Feedback” with an email address of “ [email protected] ” and a subject line “Help Microsoft Focus on Customers and Partners” from now until April 13th — it’s not a hoax or phishing email. Please open it and take a few minutes to tell them what you think. This is your chance to get your voice heard: If they’re doing well, feel free to pile on the kudos (they love positive feedback!) and if you see areas they can improve, please point them out so they can make adjustments (they also love constructive criticism!). The Microsoft team would like to thank you for all your feedback in the past — to those of you who have filled out the survey and sent them emails. Thank you to all who engage with them in so many different ways through events, the blogs, online and in person. You are why they do what they do and they feel lucky to work with such a great community! One last thing - even if you don’t get the survey you can always give the team feedback by emailing us directly through the Microsoft Canada IT Pro Feedback email address . They want to make sure they are serving you in the best possible way. Tell them what you want more of. What should they do less of or stop altogether? How can they help? Do you want more cowbell ? Let them know through the survey or the email alias. They love hearing from you!

• determining trustee of directories on novell netware volume

  - by Matt Delves

  Currently there are a lot of directories (user home directories that may no longer exist) on a netware volume. As this number is significant, I'm in need of an easy way of determining if there are any trustee's (existing users who have permissions to the directory) on the directories in question. So, several things I'm after. 1) Are there any applications, that take the input of a list of directories and output the same list with the trustee's attached? 2) Is there an easy way to determine the trustee's without looking at Console One? Thanks, Matt.

• How can I switch between the HDMI and DVI outputs of my graphics card?

  - by Owen Melbourne

  I've got an Nvidia GTX 560ti card which currently I've got my 2 monitors hooked up to using the 2 DVI ports. However its got a mini-HDMI port which I've plugged a HDMI cable in (with mini adapter) and lead it into my TV which is across the room. I'm hoping to be able to toggle between the HDMI output and the DVI outputs, however I'm not sure how I'd go about this, Could somebody please point me in the right direction, I'm not really worried about having all 3 on at the same time so that isn't a problem, but if its possible then I'll do that.

• Why do Finder and du report different file size?

  - by flipdoubt

  I am writing a geektool 3 script to show the size of a particular VMware Fusion virtual machine. Get Info in Finder says the file is "52.91 GB". I run the following du command to get the file size: > du -hs ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hs command returns the file size as "49G". What accounts for the difference from what Finder reports? Alternatively, I have tried replacing the -s option with the -d option like so: du -hd ~/Documents/Virtual\ Machines.localized/MY-PRECIOUS-7.vmwarevm | awk '{print $1}' This du -hd command returns the file size as "59G". What accounts for the difference between Finder, du -hd, and du -hs? Also, this du -hd command produces no output in geektool 3. What gives?

• Diagnosing xmodmap errors

  - by intuited

  I'm getting this error when trying to use xmodmap to get rid of caps lock: $ xmodmap -e 'clear Lock' X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 118 (X_SetModifierMapping) Value in failed request: 0x17 Serial number of failed request: 8 Current serial number in output stream: 8 I'm running xfce on Maverick "10.10" Meercat. This problem did not occur before I added the Keyboard Layouts applet to a panel; before doing that, I was able to run my xmodmap script to swap Esc and CapsLock: !Remap Caps_Lock as Escape remove Lock = Caps_Lock keysym Caps_Lock = Escape It may be relevant that I chose alt-capslock as the keyboard switch combo in the Keyboard Layouts preferences. I've had a similar problem before, on a different machine, running openbox. On that machine, this problem started when I upgraded to Lucid, and has persisted in Maverick (release 10.10). I reported a bug in xorg. However, it remains unclear whether it's really a problem with xorg, or if I'm just doing something wrong with my configuration. Have other people experienced this problem? Can someone shed some light on what's going on here? It seems there are quite a few layers involved, and I don't understand any of them particularly well, so any information would be helpful. update I've discovered that the problem is specifically triggered by adding the Canada layout variant "Multilingual" (ca-multix). If I instead add the variant "Multilingual (first part)", the problem does not occur. I think this will probably end up being a usable workaround, but I don't yet know what the difference between these variants is. I've filed a freedesktop issue, and am commenting on a related ubuntu issue.

• tcpdump selective acknowledgements question

  - by wlaus

  Hi All, I eventually sometimes watch most initial tcp connection attempts like this: tcpdump -nn -Z somepcapuser not src host (12x.x5.109.xxx or 62.75.160.xxx ) and not (port 9001 or 443 or 8080 ) and tcp[tcpflags]&(tcp-syn) !=0 and not tcp[tcpflags]& (tcp-ack) !=0 or icmp this works pretty well to quickly identify oddness so far. However, I now have a question on the following output: 03:53:52.227884 IP 203.81.166.20.53786 62.75.160.xxx.80: S 846930886:846930886(0) win 61690 "<"mss 1460,nop,nop,sackOK,opt-178:f04700000000,nop,wscale 4"" I wonder what the marked portion means, haven't seen that before.

• MPI Project Template for VS2010

  If you are developing MS MPI applications with Visual Studio 2010, you are probably tired of following some tedious steps for every new C++ project that you create, similar to the following:1. In Solution Explorer, right-click YourProjectName, then click Properties to open the Property Pages dialog box.2. Expand Configuration Properties and then under VC++ Directories place the cursor at the beginning of the list that appears in the Include Directories text box and then specify the location of the MS MPI C header files, followed by a semicolon, e.g.C:\Program Files\Microsoft HPC Pack 2008 SDK\Include;3. Still under Configuration Properties and under VC++ Directories place the cursor at the beginning of the list that appears in the Library Directories text box and then specify the location of the Microsoft HPC Pack 2008 SDK library file, followed by a semicolon, e.g.if you want to build/debug 32bit application:C:\Program Files\Microsoft HPC Pack 2008 SDK\Lib\i386;if you want to build/debug 64bit application:C:\Program Files\Microsoft HPC Pack 2008 SDK\Lib\amd64;4. Under Configuration Properties and then under Linker, select Input and place the cursor at the beginning of the list that appears in the Additional Dependencies text box and then type the name of the MS MPI library, i.e.msmpi.lib;5. In the code file#include "mpi.h"6. To debug the MPI project you have just setup, under Configuration Properties select Debugging and then switch the Debugger to launch combo value from Local Windows Debugger to MPI Cluster Debugger.Wouldn't it be great if at C++ project creation time you could choose an MPI Project Template that included the steps/configurations above? If you answered "yes", I have good news for you courtesy of a developer on our team (Qing). Feel free to download from Visual Studio gallery the MPI Project Template. Comments about this post welcome at the original blog.

• 1Tb disk formatted on Linux won't mount on windows nor mac

  - by Pedro MC

  I have an external HD (western digital) with 1Tb. I use Linux but I wanted to reserve a cross platform partition on the disk. I decided to create two partitions and used the "disks" application to do it. I created one partition with the LUKS (version 1) encryption and the other one, cross platform, in NTFS filesystem. Things work fine on my OS but when I try to use the disk (the cross platform partition) on both windows and mac the device is not recognized. What could it be? Next, output of "sfdisk -l /dev/sdb": Disk /dev/sdb: 121600 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sdb1 0+ 36473- 36473- 292968750 83 Linux /dev/sdb2 36473+ 121600- 85128- 683789062+ 83 Linux /dev/sdb3 0 - 0 0 0 Empty /dev/sdb4 0 - 0 0 0 Empty

  I work in cluster computing and am using Mac OS X 10.6. I send off hundreds of computing jobs a day, and each one comes back with with a different extension. For example, svmGeneSelect.o12345 which is the std output of my svmGeneSelect job which is job number 12345. I don't control the extensions. All files are plain text. I want OSX to open any file extension that it hasn't seen before with my favorite text editor when I click on it. Or even better set up file association defaults for extension patterns ie textEdit for extensions matching *.o*. I do NOT want to create file associations for individual files since this extension will only ever exist once, and I do not want to go through the process of selecting the application to use for each file. Thanks for any help you can offer.

• External microphone not working

  - by haireefairee

  gnome-volume-control does not recognise external hardware. My headphones work nonetheless, but an external microphone does not. External microphones used to work, but at times were temperamental - I would have to login or logout with or without microphone plugged in. I am running Ubuntu 10.04 LTS (Lucid Lynx) on an mSi U100 wind notebook with one Intel soundcard and trying to use a jack microphone which has worked previously. USB microphones have also been problematic. I have done the basics: Installed upgrades. Checked nothing is muted. Looked for the device on gnome-volume-control. Tried using a different microphone that works on a friends computer. Tested my microphone works when using a different computer. Checked my soundcard can be seen (cat /proc/asound/cards). I have done more complicated things: I have tried playing around with settings in alsamixer. Nothing is muted. I can adjust "mic" and "internal mic" regardless of whether an external microphone is plugged in. I have the choice of input source from "mic", "front mic", "line" and "CD". I've played around changing this and it hasn't helped. I only have one CAPTURE option. In gnome-sound-recorder I have the choice of line, microphone 1 and microphone 2. I have played around changing this option. None of these pick up sound from the external microphone. Microphone 2 is the microphone on my laptop which is bad quality. In gnome-sound-recorder I have the choice of different profiles, and changing this has not helped either. I have looked at gstreamer-properties but none of that seemed helpful. I don't know if there a way to check if these external devices are being picked up. I would like to make an external microphone work. Please help!

• Why are some checkboxes in Software Updater disabled?

  - by Drew Noakes

  In Ubuntu 13.04, the Software Updater shows some apps as having updates, but they're non-selectable: It's not clear why they're greyed out. On the command line: $ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done The following packages have been kept back: gnuplot-nox gnuplot-x11 nvidia-current 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded. Note too that running apt-get dist-upgrade does not cause them to be installed either, as it sometimes does with packages that are kept back. Here's the output: $ sudo apt-get dist-upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages have been kept back: gnuplot-nox gnuplot-x11 nvidia-current 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded. I took @quidage's suggestion, which gives the following. However subsequent upgrades show the same message: $ sudo apt-get install -f Reading package lists... Done Building dependency tree Reading state information... Done 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

• Synergy: server refused client

  - by Tom

  I am trying to get Synergy up and running from a new Windows 7 computer, to an XP computer. The Synergy installations seemed to go fine. I configured each to start on start-up, which they seem to, but the client won't connect. I get repeated: "server refused client with our name" messages in the log output. The Synergy FAQ says to "Add the client to the server's configuration file." But I can't seem to find an instruction set on how to do this. I've looked and looked, but I'm lost...

• Please help me, I need some solid career advice, put myself in a dumb situation

  - by Kevin

  Hi, First off, I just want to say thank you in advance for looking at my question and would really value your input on this subject. My core question is how do I proceed from the following predicament. I will be honest with you, I wasted my College Experience. I slacked off and didn't take any of my comp sci classes that seriously, somehow i still got out with a 3.25 GPA. But truth be told I learned nothing. I befriended most of my professors who went pretty lenient on me in terms of grading. However, I basically came out of College knowing how to program a simple calculator in VB.Net. I was (to my great surprise) hired by a very large respected company in Denver as a Junior developer. Well the long and the short of it is that I knew so little about programming that I quickly became the office pariah and was almost fired due to my incompetence. It has been 8 months now and I feel I have learned some basic things and I am not as picked on as I used to be by the other developers. However, everyone hates me and the first few months have given the other developers a horrible perception of me. I am no longer afraid of code or learning, but I have put my self in the precarious position of being the scapegoat of our department. I hate going to work every day because no one there is my friend and pretty much everyone is hostile to me. What should I do? Any advice?

• Can't adjust backlight on an Nvidia 335m GT

  - by Vladimir

  I have a laptop mySN QMG6 / Chiligreen Mobilitas NW which is Quanta TW9 barebone with intel i3 and nvidia 335m GT onboard. On ubuntu distros 10.04, 10.10, 11.04 and 11.10 i had problem with changing screen backlight with nouveau and nvidia drivers. FN+F4/F5 buttons did not change my brightness. I tried to edit xorg.conf, adding Option “RegistryDwords” “EnableBrightnessControl=1? Also tried to add some lines to grub acpi_osi="Linux" acpi_backlight=vendor Neither worked for me. Today I installed Ubuntu 12.04 beta2 and... With nouveau driver my FN key works, and changes the brightness (is it a new 3.0.22 linux kernel, or patched nouveau driver, i don't know). This is a big step forward. But, when installing proprietary nvidia driver (295.33) FN button stops working and i can't change brightness. I also tried workaround with xorg and grub with no result. Tried to install acpi from apt - no result. Is there anything left to try? I really need that nvidia driver working with FN keys, as i would like to have a working 3D acceleration. P.S. Does the nouveau driver has 3d acceleration like nvidia drivers??? If there is need to provide some log data, please write what should i print, as i'm a bit new to Ubuntu. P.P.S. Same problems i had with other Linux distros (Mint, Fedora and others) P.P.P.S. Other FN buttons work with both drivers (Mute, VOL UP/DOWN, WiFi on/off, Bluetooth, Sleep, Start/Pause, Stop, Next/Prev song) Some new thoughts... CONFIG_BACKLIGHT_GENERIC=m could this be an issue? Made this by grep BACKLIGHT /boot/config-3.2.0-22-generic-pae Full grep output can be viewed here: http://pastebin.com/sMRd2Z4k

• Keeping file for personal use with GPG

  - by trixcit

  I have a small text file with personal (sensitve) information. I'm currently encrypting/decrypting it with the Makefile, as described on http://www.madboa.com/geek/gpg-quickstart/ ; relevant section is edit: @umask 0077;\ $(GPG) --output $(FILEPLAIN) --decrypt $(FILECRYPT) @emacs $(FILEPLAIN) @umask 0077;\ $(GPG) --encrypt --recipient $(GPGID) $(FILEPLAIN) @$(RM) $(FILEPLAIN) view: @umask 0077; $(GPG) --decrypt $(FILECRYPT) | less this works fine for viewing, but not for editting: I first have to enter my password, then edit the file, but to encrypt it afterwards I again have to enter my password twice (and it's a long one). Is there a better way to do this?
