  • Why does my $LD_LIBRARY_PATH get unset when using screen with bash?

    - by UltraNurd
    This is related to http://superuser.com/questions/27376/why-does-my-ld-library-path-get-unset-launching-terminal, but a different set of symptoms. First, /usr/bin/screen is setuid as per the other question. Second, the default shell on this system is /bin/tcsh for various historical reasons, and we're not allowed to chsh to /bin/bash, so I typically run bash manually immediately after login. Third, I almost always use screen, but I want ctrl-a ctrl-c in screen to create a new bash "tab", so I always invoke bash first. That is: {~} $ echo $SHELL /bin/tcsh {~} $ bash [~] echo $SHELL /bin/bash [~] screen -U [~] ...and when reconnecting: {~} $ echo $SHELL /bin/tcsh {~} $ screen -dUr [~] echo $SHELL /bin/bash [~] However, my $LD_LIBRARY_PATH is there in tcsh, there in bash, but empty once I run screen; it is still present if I just run screen from tcsh, but then I get new tcsh "tabs" when I use ctrl-a ctrl-c in screen. Any ideas?

  • Animating Tile with Blitting taking up Memory.

    - by Kid
    I am trying to animate a specific tile in my 2d Array, using blitting. The animation consists of three different 16x16 sprites in a tilesheet. Now that works perfect with the code below. BUT it's causing memory leakage. Every second the FlashPlayer is taking up +140 kb more in memory. What part of the following code could possibly cause the leak: //The variable Rectangle finds where on the 2d array we should clear the pixels //Fillrect follows up by setting alpha 0 at that spot before we copy in nxt Sprite //Tiletype is a variable that holds what kind of tile the next tile in animation is //(from tileSheet) //drawTile() gets Sprite from tilesheet and copyPixels it into right position on canvas public function animateSprite():void{ tileGround.bitmapData.lock(); if(anmArray[0].tileType > 42){ anmArray[0].tileType = 40; frameCount = 0; } var rect:Rectangle = new Rectangle(anmArray[0].xtile * ts, anmArray[0].ytile * ts, ts, ts); tileGround.bitmapData.fillRect(rect, 0); anmArray[0].tileType = 40 + frameCount; drawTile(anmArray[0].tileType, anmArray[0].xtile, anmArray[0].ytile); frameCount++; tileGround.bitmapData.unlock(); } public function drawTile(spriteType:int, xt:int, yt:int):void{ var tileSprite:Bitmap = getImageFromSheet(spriteType, ts); var rec:Rectangle = new Rectangle(0, 0, ts, ts); var pt:Point = new Point(xt * ts, yt * ts); tileGround.bitmapData.copyPixels(tileSprite.bitmapData, rec, pt, null, null, true); } public function getImageFromSheet(spriteType:int, size:int):Bitmap{ var sheetColumns:int = tSheet.width/ts; var col:int = spriteType % sheetColumns; var row:int = Math.floor(spriteType/sheetColumns); var rec:Rectangle = new Rectangle(col * ts, row * ts, size, size); var pt:Point = new Point(0,0); var correctTile:Bitmap = new Bitmap(new BitmapData(size, size, false, 0)); correctTile.bitmapData.copyPixels(tSheet, rec, pt, null, null, true); return correctTile; }

  • Where do I learn about IP blocks and subnets? Or is there just a calculator that does it all for me?

    - by cwd
    Amazon's elastic compute tool (among others) requires the ip block format for their command: ec2-authorize websrv -P tcp -p 80 -s 205.192.0.0/16 I may be doing this wrong, but as far as I can tell I need to use the block format even for a single IP address. 1) So, how would I do that for this IP? 71.75.232.132 Several years ago I took a CCNA class, and I remember going over IPs and subnets, masks, broadcast addresses, class a/b/c networks, etc. However a lot seems to have changed since then - for example I don't think you can tell what "class" a network is in just by looking at it anymore - sometimes they could be multiple classes. 2) Anyhow, my second question is where do I go to get a refresher on all these things? 3) Or should I just be using ipcalc or an online calculator to do it all for me - and if so, which one?

  • Steam (via Wine) crashes after login - any troubleshooting tips?

    - by new Thrall
    The Steam client crashes after I login. After submitting my credentials, Steam displays a dialog box informing me the client is 'connecting'. I then see the Steam main page and news page displayed for roughly a second or so before the client crashes. I'm running Ubuntu 10.10 (I think..what's the best way to verify? uname only displays Linux) which I've installed on a usb flash drive using a capser-rw file for persistence. wine-1.3.14 I'm not sure how to troubleshoot.

  • Clusterware 11gR2 &ndash; Setting up an Active/Passive failover configuration

    - by Gilles Haro
    Oracle provides many interesting ways to ensure High Availability. Dataguard configurations, RAC configurations or even both (as recommended for a Maximum Available Architecture - MAA) are the most frequently found. But when it comes to protecting a system with an Active/Passive architecture with failover capabilities, one often thinks to expensive third party cluster systems. Oracle Clusterware technology, which comes free with Oracle Database, is – in the knowing of most people - often linked to Oracle RAC and therefore, is rarely used to implement failover solutions. 11gR2 Clusterware – which is part of Oracle Grid Infrastructure - provides a comprehensive framework to setup automatic failover configurations. It is actually possible to make “failover-able'” and, therefore to protect, almost every kind of application (from xclock to the more complex Application Server) In the next couple of lines, I will try to present the different steps to achieve this goal : Have a fully operational 11gR2 database protected by automatic failover capabilities. I assume you are fluent in installing Oracle Database 11gR2, Oracle Grid Infrastructure 11gR2 on a Linux system and that ASM is not a problem for you (as I am using it as a shared storage). If not, please have a look at Oracle Documentation. As often, I made my tests using an Oracle VirtualBox environment. The scripts are tested and functional. Unfortunately, there can always be a typo or a mistake. This blog entry is not a course around the Clusterware Framework. I just hope it will let you see how powerful it is and that it will give you the whilst to go further with it…   Prerequisite 2 Linux boxes (OELCluster01 and OELCluster02) at the same OS level. I used OEL 5 Update 5 with Enterprise Kernel. Shared Storage (SAN). On my VirtualBox system, I used Openfiler to simulate the SAN Oracle 11gR2 Database (11.2.0.1) Oracle 11gR2 Grid Infrastructure (11.2.0.1)   Step 1 – Install the software Using asmlib, create 3 ASM disks (ASM_CRS, ASM_DTA and ASM_FRA) Install Grid Infrastructure for a cluster (OELCluster01 and OELCluster02 are the 2 nodes of the cluster) Use ASM_CRS to store Voting Disk and OCR. Use SCAN. Install Oracle Database Standalone binaries on both nodes. Use asmca to check/mount the disk groups on 2 nodes Use dbca to create and configure a database on the primary node Let’s name it DB11G. Copy the pfile, password file to the second node. Create adump directoty on the second node.   Step 2 - Setup the resource to be protected After its creation with dbca, the database is automatically protected by the Oracle Restart technology available with Grid Infrastructure. Consequently, it restarts automatically (if possible) after a crash (ex: kill –9 smon). A database resource has been created for that in the Cluster Registry. We can observe this with the command : crsctl status resource that shows and ora.dba11g.db entry. Let’s save the definition of this resource, for future use : mkdir –p /crs/11.2.0/HA_scripts chown oracle:oinstall /crs/11.2.0/HA_scripts crsctl status resource ora.db11g.db -p > /crs/11.2.0/HA_scripts/myResource.txt Although very interesting, Oracle Restart is not cluster aware and cannot restart the database on any other node of the cluster. So, let’s remove it from the OCR definitions, we don’t need it ! srvctl stop database -d DB11G srvctl remove database -d DB11G Instead of it, we need to create a new resource of a more general type : cluster_resource. Here are the steps to achieve this : Create an action script :  /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh #!/bin/bash export ORACLE_HOME=/oracle/product/11.2.0/dbhome_1 export ORACLE_SID=DB11G case $1 in 'start')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   startup EOF   RET=0   ;; 'stop')   $ORACLE_HOME/bin/sqlplus /nolog <<EOF   connect / as sysdba   shutdown immediate EOF   RET=0   ;; 'check')    ok=`ps -ef | grep smon | grep $ORACLE_SID | wc -l`    if [ $ok = 0 ]; then      RET=1    else      RET=0    fi    ;; '*')      RET=0   ;; esac if [ $RET -eq 0 ]; then    exit 0 else    exit 1 fi   This script must provide, at least, methods to start, stop and check the database. It is self-explaining and contains nothing special. Just be aware that it is run as Oracle user (because of the ACL property – see later) and needs to know about the environment. It also needs to be present on every node of the cluster. chmod +x /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh scp  /crs/11.2.0/HA_scripts/my_ActivePassive_Cluster.sh   oracle@OELCluster02:/crs/11.2.0/HA_scripts Create a new resource file, based on the information we got from previous  myResource.txt . Name it myNewResource.txt. myResource.txt  is shown below. As we can see, it defines an ora.database.type resource, named ora.db11g.db. A lot of properties are related to this type of resource and do not need to be used for a cluster_resource.

Notice the NAME property that should not have the ora. prefix Notice the TYPE property that is not ora.database.type but cluster_resource. Notice the definition of ACTION_SCRIPT.

Take care of the resource type. It needs to be a cluster_resource and not a ora.database.type resource (Oracle recommendation) .   crsctl add resource DB11G.db  -type cluster_resource -file /crs/11.2.0/HA_scripts/myNewResource.txt Step 3 - Start the resource crsctl start resource DB11G.db This command launches the ACTION_SCRIPT with a start and a check parameter on the primary node of the cluster. Step 4 - Test this We will test the setup using 2 methods. crsctl relocate resource DB11G.db This command calls the ACTION_SCRIPT  (on the two nodes)  to stop the database on the active node and start it on the other node. Once done, we can revert back to the original node, but, this time we can use a more “MS$ like” method :Turn off the server on which the database is running. After short delay, you should observe that the database is relocated on node 1. Conclusion Once the software installed and the standalone database created (which is a rather common and usual task), the steps to reach the objective are quite easy : Create an executable action script on every node of the cluster. Create a resource file. Create/Register the resource with OCR using the resource file. Start the resource. This solution is a very interesting alternative to licensable third party solutions.   References Clusterware 11gR2 documentation Oracle Clusterware Resource Reference   Gilles Haro Technical Expert - Core Technology, Oracle Consulting

  • Crafty.js multiplayer platform game, keeping players in sync

    - by johnwards
    I'm using crafty.js to create a very simple platform game. It doesn't need to stop cheating, it's actually just seeing other players move around, and it doesn't need to have collision detection between players. They are "shadows". How I've gone about it so far is to use http://pubnub.com to send messages between clients. These messages are simple. The first if a new player arrival, the second is a key down and the third is a key up. The code is here: https://github.com/whiteoctober/craftyconcept However I've hit against the old chestnut of keeping everything in sync. At the moment I'm letting the each of the clients decide where to place the other players based on the received key events, I also only move "you" until I get a key press event back from pubsub. My thinking here is to try and keep things in sync! However it isn't perfect, http://www.whiteoctober.co.uk/john/gametest/, things can get out of sync very easily. Key presses arrive in the wrong order etc. Is there any simple solutions to this, I would like to keep it all client side (with pubnub) and not have a central server with positions etc if possible.

  • unity, seeing all instances of same open application windows on all virtual desktop

    - by Nasser M. Abbasi
    I noticed this strange issue with unity. I am using 12.04. The desktop has 4 virtual desktops, which I can switch between using the 'workspace switcher' which is very nice. But I noticed the following: When I have 2 instances of the same app (say 2 different firefox windows, or 2 different terminal windows), in 2 different virtual desktops, then I click on the icon for that application located on the launcher panel (the left long strip with icons on it), then I see the application comes into focus. Then when I click again right away (on the same icon on the launcher), then now all instances of this application that are open come into ONE view (may be on was on desktop 1, and the other was on desktop 3 for example) and then I can now click on the one instance window that I want to select to use. This is all very nice actually. But this does NOT work for all applications! I just tried it, and it worked for firefox, and for gedit and for the gnome terminal. I have one firefox window open in virtual desktop 1, and another window open in virtual desktop 2. I clicked once on the firefox icon, then again, and both windows came into the main desktop and I was able to select which one to use. When I tried the same thing on dolphin file manager, which I also had 2 windows (instances) of it open in 2 different virtual desktops, this behavior did not happen. I clicked again, and nothing happened. Only one remained in focus. So I had to fo look for the second dolphin window the hard way. It looks like some apps are supported by this feature and some are not. How does one make it so that all applications are supported like this? This is a very handy feature. Is it a configuration item somewhere? thanks

  • Render on other render targets starting from one already rendered on

    - by JTulip
    I have to perform a double pass convolution on a texture that is actually the color attachment of another render target, and store it in the color attachment of ANOTHER render target. This must be done multiple time, but using the same texture as starting point What I do now is (a bit abstracted, but what I have abstract is guaranteed to work singularly) renderOnRT(firstTarget); // This is working. for each other RT currRT{ glBindFramebuffer(GL_FRAMEBUFFER, currRT.frameBufferID); programX.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, firstTarget.colorAttachmentID); programX.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, firstTarget.depthAttachmentID); programX.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); // quadBuffID is a VBO for a screen aligned quad. It is fine. programX.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS,0,4); programY.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, currRT.colorAttachmentID); // The second pass is done on the previous pass programY.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, currRT.depthAttachmentID); programY.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); programY.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS, 0, 4); } The problem is that I end up with black textures and not the wanted result. The GLSL programs program(X,Y) works fine, already tested on single targets. Is there something stupid I am missing? Even an hint is much appreciated, thanks!

  • Booting sequence. Ubuntu 12.04 installation and cohabitation with former OSes

    - by Stephane Rolland
    I am on the brink of installing Ubuntu 12.04 Precise Pengolin on the first primary partition of my hard-drive. (A day in History for me since I had always kept a MS windows at this first place). But I have some fears: This is my last computer available (In the past I used to have 2 or even 3 machines so I could always un/plug HDs for recovery operations and rescue) The current booting sequence is not straight forard. So as to explain the boot sequence let me briefly sum-up the history of this laptop computer. It was a dedicated Windows Vista computer. 1st and only Primary partition. Then I added Windows 7 (on the 2nd primary partition) letting the Windows Vista Boot Loader manage the boot sequence. Then I added Ubuntu 10.04 Lucid Lynx on the 1st sub-partition of the Extended Partitionm asking Grub to be the boot loader. But when I ask Grub to launch windows it launches the Vista BootLoader that manages the choice betzeen Vista and 7. So in theory Grub is on the MasterBootRecord - though I understand where the Vista BootLoader remains. Now, I will no longer use the Ubuntu 10.04 ( on extended partition) and also the Windows vista (on the first primary partition). I will install Ubuntu 12.04 on the First Primary, asking it to install a new bootloader. I want to keep the Windows 7 that is already on the Second Primary partition. And I want it to be loaded by the Ubuntu Boot loader(I don4t knoz zhich is included in this version)... And I am afraid the last point will not work.

  • Unity3d: calculate the result of a transform without modifying transform object itself

    - by Heisenbug
    I'm in the following situation: I need to move an object in some way, basically rotating it around its parent local position, or translating it in its parent local space (I know how to do this). The amount of rotation and translation is know at runtime (it depends on several factors, the speed of the object, enviroment factors, etc..). The problem is the following: I can perform this transformation only if the result position of the transformed object fit some criterias. An example could be this: the distance between the position before and after the transformation must be less than a given threshold. (Actually the conditions could be several and more complex) The problem is that if I use Transform.Rotate and Transform.Translate methods of my GameObject, I will loose the original Transform values. I think I can't copy the original Transform using instantiate for performance issues. How can I perform such a task? I think I have more or less 2 possibilities: First Don't modify the GameObject position through Transform. Calculate which will be the position after the transform. If the position is legal, modify transform through Translate and Rotate methods Second Store the original transform someway. Transform the object using Translate and Rotate. If the transformed position is illegal, restore the original one.

  • Enumerable Interleave Extension Method

    - by João Angelo
    A recent stackoverflow question, which I didn’t bookmark and now I’m unable to find, inspired me to implement an extension method for Enumerable that allows to insert a constant element between each pair of elements in a sequence. Kind of what String.Join does for strings, but maintaining an enumerable as the return value. Having done the single element part I got a bit carried away and ended up expanding it adding overloads to support interleaving elements of another sequence and support for a predicate to control when interleaving takes place. I have to confess that I did this for fun and now I can’t think of any real usage scenario, nonetheless, it may prove useful for someone. First a simple example: var target = new string[] { "(", ")", "(", ")" }; var result = target.Interleave(".", (f, s) => f == "("); // Prints: (.)(.) Console.WriteLine(String.Join(string.Empty, result)); And now the untested but documented implementation: using System; using System.Collections; using System.Collections.Generic; using System.Linq; public static class EnumerableExtensions { /// <summary> /// Iterates infinitely over a constant element. /// </summary> /// <typeparam name="T"> /// The type of element in the sequence. /// </typeparam> private class InfiniteSequence<T> : IEnumerable<T>, IEnumerator<T> { public InfiniteSequence(T element) { this.Element = element;

  • conditional formatting for subsequent rows or columns

    - by Trailokya Saikia
    I have data in a range of cells (say six columns and one hundred rows). The first four column contains data and the sixth column has a limiting value. For data in every row the limiting value is different. I have one hundred such rows. I am successfully using Conditional formatting (e.g. cells containing data less than limiting value in first five columns are made red) for 1st row. But how to copy this conditional formatting so that it is applicable for entire hundred rows with respective limiting values. I tried with format painter. But it retains the same source cell (here limiting value) for the purpose of conditional formatting in second and subsequent rows. So, now I am required to use conditional formatting for each row separately s

  • Hybrid USB Install Method - netboot and iso

    - by Samus Arin
    I was following the steps here ("Preparing Files for USB Memory Stick Booting") https://help.ubuntu.com/10.04/installation-guide/i386/boot-usb-files.html to create a installation usb drive for 12.1. The very first paragraph of the article states "The second is to also copy a CD image onto the USB stick and use that as a source for packages, possibly in combination with a mirror." However, the only instructions mentioned regarding an iso image is to simply copy one somewhere on the drive (after its been made bootable and syslinux, vmlinuz and initrd.gz installed/copied): "you should now copy an Ubuntu ISO image onto the stick." I thought it strange there where no configuration steps for "pointing" the kernel to the iso (like a line in syslinux.cfg or a boot: option or something), but went ahead with the install anyway. I don't think the iso was used at all, it appeared that all the OS files where downloaded during the install process. Therefore, I was wondering if anyone knew how to use this local iso image in this particular installation technique (I know the image can be installed with dd, but thats a different technique), b/c I need to reinstall (I installed unity, but it's wayy to much for my little Atom based netbook) ? Thank you.

  • Multiple audio sources on a single gameObject in unity

    - by angryInsomniac
    So, I have an audio system set up wherein I have loaded all my audio clips centrally and play them on demand by passing the requesting audioSource into the sound manager. However, there is a complication wherein if I want to overlay multiple looping sounds, I need to have multiple audio sources on an object, which is fine , so I created two in my script instantiated them and played my clips on them and then the world went crazy. For some reason, when I create two audio Sources in an object only the latest one is ever used, even if I explicitly keep objects separated, playing a clip on one or the other plays the clip on the last one that was created, furthermore, either this last one is not created in the right place or somehow messes with the rolloff rules because I can hear it all across my level, havign just one source works fine, but putting a second one on it causes shit to go batshit insane. Does anyone know the reason / solution for this ? Some pseudocode : guardSoundsSource = (AudioSource)gameObject.AddComponent("AudioSource"); guardSoundsSource.name = "Guard_Sounds_source"; // Setup this source guardThrusterSource = (AudioSource)gameObject.AddComponent("AudioSource"); guardThrusterSource.name = "Guard_Thruster_Source"; // setup this source // play using custom Sound manager soundMan.soundMgr.playOnSource(guardSoundsSource,"Guard_Idle_loop" ,true,GameManager.Manager.PlayerType); // this method prints out the name of the source the sound was to be played on and it always shows "Guard_Thruster_Source" even on the "Guard_Idle_loop" even though I clearly told it to use "Guard_Sounds_source"

  • Flash AS3 sidescrolling tiles optimization

    - by Galvanize
    I'm trying to make a sidescrolling game in Flash that will run on a low performance laptop. While studying the subject from Tonypa I saw that he builds a Bitmap by making copys of the BitmapData of each tile from the Tile Sheet and placing it on the bigger Bitmat with the size of the screen. But when I came to think on how to scroll my map I ran into some optimization doubts. I came up with two choices: Create a MovieClip, place a Bitmap instance for each tile that is shown on the screen + 1 row in it, then move them all. Then when the tile ran off the screen I would move it to end of the MovieClip and replace their BitmapData for the next row in my map. Use a Bitmap with copys of each tile in it (as shown in Tonypa's tutorial) but 1 extra row, move the whole Bitmap, and when it comes the time to replace rows, redraw the whole Bitmap and move it back to the origin position. The first idea is how a co-worker of mine suggested, the second one is my own, but none of us has enough technical knowledge to be sure on a technique that would be optimal in performance, can anyone help?

To my understanding hard faults should be fairly rare on a machine with. Are there any logs I can show you? Or investigate myself. The general performance of the machine is ok, i can access SBS2008 and change settings fairly smoothly without hangs etc. However, we connect to the server and do quite a bit of SQL via an application.

  • A Trip to the Moon (Le Voyage dans la Lune) [Super Retro Classic Sci-Fi Video]

    - by Asian Angel
    If you are into retro sci-fi movies, then you will definitely want to have a look at this French classic from 1902. This silent movie is only 10.5 minutes long, but is well worth watching and makes for a fun romp through the early days of sci-fi. From YouTube: A Trip to the Moon (French: Le Voyage dans la lune) is a 1902 French black and white silent science fiction film. It is loosely based on two popular novels of the time: From the Earth to the Moon by Jules Verne and The First Men in the Moon by H. G. Wells. The film was written and directed by Georges Melies, assisted by his brother Gaston. The film runs 14 minutes if projected at 16 frames per second, which was the standard frame rate at the time the film was produced. It was extremely popular at the time of its release and is the best-known of the hundreds of fantasy films made by Melies. A Trip to the Moon is the first science fiction film, and utilizes innovative animation and special effects, including the iconic shot of the rocketship landing in the Moon’s eye.

  • Meaningful concise method naming guidelines

    - by Sam
    Recently I started releasing an open source project, while I was the only user of the library I did not care about the names, but know I want to assign clever names to each methods to make it easier to learn, but I also need to use concise names so they are easy to write as well. I was thinking about some guidelines about the naming, I am aware of lots of guidelines that only care about letters casing or some simple notes. Here, I am looking after guidelines for meaningful concise naming. For example, this could be part of the guidelines I am looking after: Use Add when an existing item is going to be added to a target, Use Create when a new item is being created and added to a target. Use Remove when an existing item is going to be removed from a target, Use delete when an item is going to be removed permanently. Pair AddXXX methods with RemoveXXX and Pair CreateXXX methods with DeleteXXX methods, but do not mix them. The above guidance may be intuitive for native English speakers, but for me that English is my second language I need to be told about things like this.

  • Graphics performance of 945GME

    - by l0b0
    Edit: Since setting Appearance - Visual Effects up to a stunning "Normal", I now get ~35 FPS in glxgears right after login, with nothing else running :( I'm getting terrible graphics performance in NeverWinter Nights (native with SoU+HotU+CEP2) on my Eee PC 1005HAB. Even with all graphics settings (including the "advanced" ones) at minimum I get about 2-10 FPS, depending on the scene. Firefox is really sluggish as well - Changing tabs often takes a second, scrolling is laggy, and typing this I notice the delay between pressing keys and seeing the text on screen. The rest of the OS is running OK, although general performance seems to be even worse than my old Eee PC 900. glxgears gives about 60 FPS, which is apparently as it should be (synchronized with the monitor refresh rate). Bugs like Launchpad #252094 and the instructions for Reverting the Jaunty Xorg intel driver to 2.4 are old enough that I'm afraid following the instructions would render the system unusable. Are there any tips for improving graphics performance on this system that are still relevant for 10.10? $ uname -a Linux l0b0eee 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:40:58 UTC 2011 i686 GNU/Linux $ lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03) $ glxinfo name of display: :0.0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.4 ...

  • linux need to discover local sata mirror before hba attached scsi

    - by Ryan
    (none of the machines mentioned are in production) Hello, I'm trying to install Centos 5.4, which wants to put the boot loader on either the boot sector of the boot drive (a local SATA mirror, recognized second as sdb) or the mba of a hba-attached SCSI array (recognized first as sda). There's a LILO install already on the mba of sdb, which keeps trying to boot first. If I zero out the MBA of sdb, would the boot loader at sdb1 be found and booted? I was thinking of that as a plan B, as I was mostly thinking of coaxing CentOS to find the local mirror first and bring that up as sda, but I haven't found info on how to do this anywhere.

  • DAO/Webservice Consumption in Web Application

    - by Gavin
    I am currently working on converting a "legacy" web-based (Coldfusion) application from single data source (MSSQL database) to multi-tier OOP. In my current system there is a read/write database with all the usual stuff and additional "read-only" databases that are exported daily/hourly from an Enterprise Resource Planning (ERP) system by SSIS jobs with business product/item and manufacturing/SCM planning data. The reason I have the opportunity and need to convert to multi-tier OOP is a newer more modern ERP system is being implemented business wide that will be a complete replacement. This newer ERP system offers several interfaces for third party applications like mine, from direct SQL access to either a dotNet web-service or a SOAP-like web-service. I have found several suitable frameworks I would be happy to use (Coldspring, FW/1) but I am not sure what design patterns apply to my data access object/component and how to manage the connection/session tokens, with this background, my question has the following three parts: Firstly I have concerns with moving from the relative safety of a SSIS job that protects me from downtime and speed of the ERP system to directly connecting with one of the web services which I note seem significantly slower than I expected (simple/small requests often take up to a whole second). Are there any design patterns I can investigate/use to cache/protect my data tier? It is my understanding data access objects (the component that connects directly with the web services and convert them into the data types I can then work with in my Domain Objects) should be singletons (and will act as an Adapter/Facade), am I correct? As part of the data access object I have to setup a connection by username/password (I could set up multiple users and/or connect multiple times with this) which responds with a session token that needs to be provided on every subsequent request. Do I do this once and share it across the whole application, do I setup a new "connection" for every user of my application and keep the token in their session scope (might quickly hit licensing limits), do I set the "connection" up per page request, or is there a design pattern I am missing that can manage multiple "connections" where a requests/access uses the first free "connection"? It is worth noting if the ERP system dies I will need to reset/invalidate all the connections and start from scratch, and depending on which web-service I use might need manually close the "connection/session"

  • Learn to Take a Punch, Learn to Counter, Keep Moving Forward

    - by D'Arcy Lussier
    Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/10/28/154483.aspxDuring a boxing workout a few months ago our trainer had us do something called “breadbaskets”. That’s where you hold your arms up and a partner punches you in your midsection – your breadbasket. I put my arms up, and braced for impact. The trainer came over, saw I was a bit nervous, and coached me through. I can see the fear in your eyes. Don’t be afraid to take the punch. Tighten your core, breathe through the hit. Don’t panic. Over the summer we’d do counter drills as well. This is where a partner throws a punch, you defend but also throw one back – a counter punch. You never just sit back and take a beating, you deflect the blow and come back with one more powerful. These lessons on fighting can apply to all aspects of our lives and any attempts at success that we have. I saw this image recently and agree with it 100%: Success is never a straight forward line. It’s messy, its wrought with failures, its learning over time and applying those life lessons. It’s learning how to take punches and lose your fear, its seeing a punch coming and countering it, but most of all its not giving up and continually moving forward. We do stairs at boxing, which is running up and down three flights of stairs. I’m not anywhere near incredible shape and after doing multiple stairs in a single workout you can feel gassed, tired, even discouraged after hitting the second floor and seeing everyone else running by you. I read a quote from Martin Luther King Jr. that I cling to throughout my day: You want to be successful? Take the punches, but learn how to take them. Counter them. and no matter what, always move forward.
