• crontab still sending emails even with > /dev/null

  - by user2344668

  I have a crontab (root) that runs a script and output is set to /dev/null but I always get the emails whenever it runs. I only want to receive error emails. # Rackspace driveclient update (12pm MST) 0 12 * * * /root/scripts/driveclient-update > /dev/null The only way I can get it to turn off is to use /dev/null 2&1 but then I won't get error emails. This is happening on three different CentOS servers, two are 6.3 and one is 6.4. NOTE: I have read over and over that /dev/null is supposed to send stdout there and prevent the email if there is nothing but stdout from the script, so at works for at least some people; I cannot figure out why it is not working on these servers. Here's an example of where /dev/null is supposed to work: http://www.alphadevx.com/a/384-Suppressing-Cron-Job-Email-Notifications

• Position sprite at center of screen

  - by Wellie

  I am trying to get a sprite to position itself at the center of the screen but nothing seems to be working for me. I'm trying Viewport viewport = graphics.GraphicsDevice.Viewport; logoPosition = new Vector2((viewport.Width - towerImage.Width) / 2, (viewport.Height - towerImage.Height) / 2); and spriteBatch.Draw(towerImage, centre, null, Color.White, 0, baseOrigin, 1.0f, SpriteEffects.None, 0); This is my first time using XNA and I don't really have a clue what I'm doing.

• apt-get -f install removed software center and several other files

  - by user287858

  I ran sudo apt-get -f install and several files and programs were removed including software center. Is there a way to re-download everything as if ubuntu was new again without a cd? This computer does not have a cd-rom drive. I'd be fine with losing all the data on this computer. Also, when I run sudo apt-get install (almost anything) I get errors about dependencies and files not being available. Thanks to anyone who can help.

• /dev/null file became regular file

  - by user197719

  In our production server suddenly /dev/null became a regular file and due to this sshd service got stopped and not able to login the server. And also we tried to the below steps to configure back to character device file, rm -rf /dev/null mknod /dev/null c 1 3 As soon as we run the rm command /dev/null is being re-created as a regular file before mknod can run. We can't figure out how this happening and which component is creating this file. So until we solve this issue we are unable to create /dev/null as character device file.

• KVM guest io is much slower than host io: is that normal?

  - by Evolver

  I have a Qemu-KVM host system setup on CentOS 6.3. Four 1TB SATA HDDs working in Software RAID10. Guest CentOS 6.3 is installed on separate LVM. People say that they see guest performance almost equal to host performance, but I don't see that. My i/o tests are showing 30-70% slower performance on guest than on host system. I tried to change scheduler (set elevator=deadline on host and elevator=noop on guest), set blkio.weight to 1000 in cgroup, change io to virtio... But none of these changes gave me any significant results. This is a guest .xml config part: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/vgkvmnode/lv2'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> There are my tests: Host system: iozone test # iozone -a -i0 -i1 -i2 -s8G -r64k random random KB reclen write rewrite read reread read write 8388608 64 189930 197436 266786 267254 28644 66642 dd read test: one process and then four simultaneous processes # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct 1073741824 bytes (1.1 GB) copied, 4.23044 s, 254 MB/s # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 14.4528 s, 74.3 MB/s 1073741824 bytes (1.1 GB) copied, 14.562 s, 73.7 MB/s 1073741824 bytes (1.1 GB) copied, 14.6341 s, 73.4 MB/s 1073741824 bytes (1.1 GB) copied, 14.7006 s, 73.0 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 6.2039 s, 173 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 32.7173 s, 32.8 MB/s 1073741824 bytes (1.1 GB) copied, 32.8868 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9097 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9688 s, 32.6 MB/s Guest system: iozone test # iozone -a -i0 -i1 -i2 -s512M -r64k random random KB reclen write rewrite read reread read write 524288 64 93374 154596 141193 149865 21394 46264 dd read test: one process and then four simultaneous processes # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 1073741824 bytes (1.1 GB) copied, 5.04356 s, 213 MB/s # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 24.7348 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7378 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7408 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.744 s, 43.4 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 10.415 s, 103 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 49.8874 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8608 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8693 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.9427 s, 21.5 MB/s I wonder is that normal situation or did I missed something?

• How to record tv to network share with Windows Media Center?

  - by Peterdk

  Well, you would think that Windows 7's new MediaCenter would be up to the task of recording your TV to a network share/drive. Too bad, it looks like it's just not possible. I have a windows 2008 R2 server, and a Windows 7 machine with a TV card. Since my server has 2TB of storage, it would be nice to record directly to it's networked drive. (I mounted it as Z:). I tried the following: Selecting it in Media Center Itself: Not working. Not available. Editing the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\Recording , setting RecordPath to Z:\TV. Not working. Editing the registry: setting RecordPath to \\server\TV. Not working. Creating a Symlink (mklink \D) to Z:\TV and \\server\TV and setting that in the registry as RecordPath. Currently I am out of options. I could ofcourse Install Windows7 on my server, but I have no license for that, and my windows 2008 r2 is free from dreamspark. Are there people that are succesfully recording to a networked drive/storage? edit I also need to mention that I need to be able to acces the stored files from other PC's, like my laptop. So iSCSI is great for recording, but it looks like you can't access iSCSI devices from multiple PC's. Looks like sharing a iSCSI device is out of the question, so: Are there workarounds to get this thing recording to my network drive?

• How can I center something if I don't know ahead of time what the width is?

  - by zeckdude

  I am trying to center a paragraph tag with some text in it within a div, but I can't seem to center it using margin: 0 auto without having to specify a fixed width for the paragraph. I don't want to specify a fixed width, because I will have dynamic text coming into the paragraph tag and it will always be a different width based on how much text it is. Does anyone know how I can center the paragraph tag within the div without having to specify a fixed width for the paragraph or without using tables?

• A view from the call center for the Nashville Flood telethon

  - by Rob Foster

  I want to break away from my usual topic of something technical and talk about what I experienced tonight while working in the call center for the Nashville Flood telethon, which was broadcast on WSMV, CNN, and The Weather Channel.  We started receiving calls about 7pm local time and to be honest, I had no idea what to expect when going into this.  I mean, I'm a pretty good talker, but this is different...We had a good script of what to say and how we were supposed to say it, as well as paper forms and pens that we used to collect information from people who wanted to donate their money to help.  I took my first few calls pretty easily and it went pretty quick and easy.  Everyone was upbeat and happy to be in the call center as well as people happy to be donating money. Pizza, snacks, and soft drinks were flowing well.  Everyone is smiling and happy.  :) About 3 or 4 calls into my night, I got a call from a lady that had lost 2 family members in West Nashville who drowned in the floods.  She was crying when she called and I of course tried to console her.  She told me how bad her situation was, losing family members and much of her neighborhood.  After all this, she still just wanted to help other people.  She was donating all the money that she could to the telethon and I want to share a direct quote from her: "I want to donate this instead of buying flowers for my family members' funeral because people out there need help.". Please let me pause while I get myself together <again>.  That caught me so off guard (and still does). I had kids calling wanting to donate their allowance, open their piggy banks, whatever they could do.  These are kids.  Kids not much older than my boys.  Kids who should be focused on buying the next cool video game or toy or whatever but wanted to do something.  Everyone just seemed to want to help. I took calls from as far away as British Columbia as well and pretty much coast to coast.  how cool is that? Yet another thing that caught me off guard.  This kind lady that called from British Columbia told me how much she loved visiting Nashville and just hated to see this happen.  I belive that she said that she will be attending the CMA Fest this year too.  I was sure to tell her not to cancel her plans!  :) It felt like every call I took (and I took A LOT, as did everyone else) was very personal and heartfelt.  I've never had the privelage to do anything like this and fell lucky to have been able to help out with answering phones and logging donations.  Nashville will bounce back very quickly, people are out there day and night helping each other, and the spirits are very high here.  I hope that one day, my kids read this blog and better understand who they are, where they come from, and what the human spirt is and can be.  I love this city, I love the people here, I love the culture and even more than ever am proud to say that this is me.  This is us.  We are Nashville!

• Role Center Installation for IIS Default Feature XPS-VIEWER

  - by ssmantha

  While installing Dynamics Ax 2009 Roles Center and Enterprise Portal on Windows Server 2008 R2, there is a prerequisite for IIS Default components which fails to install. The error log file for IIS component installation points to an error while installing feature NET-XPS-VIEWER. This issue can be resolved by editing “ServerManagerCmdInputIIS.xml” file present in the support folder of the DAX 2009 installer. Edit the entry “<Feature Id="NET-XPS-Viewer" />” to “<Feature Id="NET-XPS-Viewer" />” and try reinstalling the installer should now continue uninterrupted. The issue is due to the feature name which is now XPS-VIEWER in windows server 2008 R2. Happy Installing!! :-)

My class, looks as follows: using UnityEngine; using System.Collections; public class PerspectiveOffCenter : MonoBehaviour { // Use this for initialization void Start () { } // Update is called once per frame void Update () { } public static Matrix4x4 GeneralizedPerspectiveProjection(Vector3 pa, Vector3 pb, Vector3 pc, Vector3 pe, float near, float far) { Vector3 va, vb, vc; Vector3 vr, vu, vn; float left, right, bottom, top, eyedistance; Matrix4x4 transformMatrix; Matrix4x4 projectionM; Matrix4x4 eyeTranslateM; Matrix4x4 finalProjection; ///Calculate the orthonormal for the screen (the screen coordinate system vr = pb - pa; vr.Normalize(); vu = pc - pa; vu.Normalize(); vn = Vector3.Cross(vr, vu); vn.Normalize(); //Calculate the vector from eye (pe) to screen corners (pa, pb, pc) va = pa-pe; vb = pb-pe; vc = pc-pe; //Get the distance;; from the eye to the screen plane eyedistance = -(Vector3.Dot(va, vn)); //Get the varaibles for the off center projection left = (Vector3.Dot(vr, va)*near)/eyedistance; right = (Vector3.Dot(vr, vb)*near)/eyedistance; bottom = (Vector3.Dot(vu, va)*near)/eyedistance; top = (Vector3.Dot(vu, vc)*near)/eyedistance; //Get this projection projectionM = PerspectiveOffCenter(left, right, bottom, top, near, far); //Fill in the transform matrix transformMatrix = new Matrix4x4(); transformMatrix[0, 0] = vr.x; transformMatrix[0, 1] = vr.y; transformMatrix[0, 2] = vr.z; transformMatrix[0, 3] = 0; transformMatrix[1, 0] = vu.x; transformMatrix[1, 1] = vu.y; transformMatrix[1, 2] = vu.z; transformMatrix[1, 3] = 0; transformMatrix[2, 0] = vn.x; transformMatrix[2, 1] = vn.y; transformMatrix[2, 2] = vn.z; transformMatrix[2, 3] = 0; transformMatrix[3, 0] = 0; transformMatrix[3, 1] = 0; transformMatrix[3, 2] = 0; transformMatrix[3, 3] = 1; //Now for the eye transform eyeTranslateM = new Matrix4x4(); eyeTranslateM[0, 0] = 1; eyeTranslateM[0, 1] = 0; eyeTranslateM[0, 2] = 0; eyeTranslateM[0, 3] = -pe.x; eyeTranslateM[1, 0] = 0; eyeTranslateM[1, 1] = 1; eyeTranslateM[1, 2] = 0; eyeTranslateM[1, 3] = -pe.y; eyeTranslateM[2, 0] = 0; eyeTranslateM[2, 1] = 0; eyeTranslateM[2, 2] = 1; eyeTranslateM[2, 3] = -pe.z; eyeTranslateM[3, 0] = 0; eyeTranslateM[3, 1] = 0; eyeTranslateM[3, 2] = 0; eyeTranslateM[3, 3] = 1f; //Multiply all together finalProjection = new Matrix4x4(); finalProjection = Matrix4x4.identity * projectionM*transformMatrix*eyeTranslateM; //finally return return finalProjection; } // Update is called once per frame public void FixedUpdate () { Camera cam = camera; //calculate projection Matrix4x4 genProjection = GeneralizedPerspectiveProjection( new Vector3(0,1,0), new Vector3(1,1,0), new Vector3(0,0,0), new Vector3(0,0,0), cam.nearClipPlane, cam.farClipPlane); //(BottomLeftCorner, BottomRightCorner, TopLeftCorner, trackerPosition, cam.nearClipPlane, cam.farClipPlane); cam.projectionMatrix = genProjection; } } My error lies in projectionM = PerspectiveOffCenter(left, right, bottom, top, near, far); The debugger states: Expression denotes a `type', where a 'variable', 'value' or 'method group' was expected. Thus, I changed the line to read: projectionM = new PerspectiveOffCenter(left, right, bottom, top, near, far); But then the error is changed to: The type 'PerspectiveOffCenter' does not contain a constructor that takes '6' arguments. For reasons that are obvious. So, finally, I changed the line to read: projectionM = new GeneralizedPerspectiveProjection(left, right, bottom, top, near, far); And the error I get is: is a 'method' but a 'type' was expected. With this last error, I'm not sure what it is I should do / missing. Can anyone see what it is that I'm missing to fix this error?

• Steady zoom on center in LWJGL (Modelview)

  - by l5p4ngl312

  I am having a problem in LWJGL with zooming in and out. I am using glScaled(zoom, zoom, 1) before glTranslated. There are 2 problems: 1. The rate of zoom speeds up a lot when zooming out (lower zoom value). 2. It zooms in on the bottom left corner of the screen rather than the center. Eventually, I would like to have the zoom focused on the mouse position. I have tried to fix these problems by make it glScaled(zoom^12, zoom^12, 1) so that the greater the zoom value, the faster it will zoom in order to balance out the faster zoom at lower zoom values. To compensate for the zoom focused on the bottom left, I have tried to subtract (zoom+1)^10 + 2^10 from the X and Y of each sprite. This results in a curved zoom path, first to the left and then to the right. It is a 2D game.

• A tale of two dev accounts

  - by TechTwaddle

  Note: I am currently in the process of relocating my blog from http://www.geekswithblogs.net/techtwaddle to my new address at http://www.techtwaddle.net I suggest you point your feed readers to the new address as I slowly transition to my new shared-hosted, ad-free wordpress blog :)   You probably remember my rant from a while back about my windows mobile developer account having problems with the new AppHub, well, there have been few developments and I thought I should share it with you. First up, the issue isn’t fixed yet. I still cannot login to AppHub using my windows mobile 6.x developer account and can’t view details of my Minesweeper app. Who knows how many copies its sold. I had numerous exchanges with Microsoft’s support team on the AppHub forums and via email as well (support ticket), but somehow we never managed to get to the root of it. In fact, the support team itself grew so tired of the problem that they suggested I create a new dev account. I grew impatient, and it was really frustrating to have an app ready for submission but not being able to do anything with it. Eventually, the frustration had to show somewhere, and it was on this forum thread Prabhu Kumar in reply to Nick Nick, I feel for you and totally understand the frustration. Since day one I have been getting the XBOX profile linking error, We encountered an issue connecting your App Hub account with your Xbox Live Profile. Please visit Xbox.com and update your contact information. After you have updated your contact information, please return to the App Hub (https://users.create.msdn.com/Register) to continue. I have an app published on the Windows Mobile 6.x marketplace since Aug, now I can't view the details of this app. I completed work on my WP7 application 1.5 months ago and the first version is ready for submission to marketplace, only if I can login. You can imagine how frustrating all this can be, the issue has taken far too long to be fixed, this has drained all my motivation. I have exchanged numerous mails with Microsoft support team on this issue, and from the looks of it they really are trying their best, unfortunately, their best is not good enough for some of us. During the first week of December I was told that there would be an update happening to AppHub around mid of December. I was hoping that the issue would be fixed but it wasn't. After the update the only change I notice is that the xbox.com link on the error page now takes me to the correct link. Previously, this link used to take me to the 404 page you mentioned above. Out of desperation, I am now considering creating another developer account on AppHub with a new live id, even this I am not 100% sure will work. I asked the support team when the next update to AppHub was planned and got this reply, "We do not have  release date to announce for the next App Hub update at this time. In regards to the login issue you are experiencing at this point the only solution would be to create a new account with a different live ID but make sure to go to xbox.com before hand to get all the information in order on that side." I know it's an extra $99, and not that I can't afford it but it doesn't feel right and I shouldn't have to be doing it in the first place. I have lost all hope of this issue being resolved. I went ahead and created a new dev account, the id verification was in progress when Shaun Taulbee of Microsoft, who has been really helpful in the forums, replied saying, If you find it necessary to pay again to create a new account due to a Microsoft problem, send in a support request asking for a refund and we'll review it (and likely approve it given the circumstances). The thought of refund made me happy, but I had my doubts. So once my second account was verified by Geotrust I applied for a refund through the developer dashboard, by creating a support ticket. Couple of days later I got an email from Microsoft saying that the refund had been approved! yay! Few days and the refund showed up on my bill, Well, thank you Microsoft, it means a lot. I am glad it’s over now. The new account works flawlessly. I would still like to get my first account working again and look at my app numbers for Win Mo 6.x, and probably transfer the credits to the new account somehow, but I’ll save it for another day. If you’ve had similar problems with the AppHub, and had to create a new account to submit your app, I suggest you contact the support team and get your dollars refunded!
