  • Do support sites like Stack Overflow upset the paid-support open source model?

    - by ajax81
    In order to stay relevant in the marketplace, I'm researching new business models for my software company. The open source model with paid support seems like a good fit for our product, but I have concerns about whether or not a paid support model is viable in an era where top-notch help is readily available for free on sites like those in the Stack Exchange network. Case in point -- I moved my employees to Ubuntu last year because I didn't want to pay for Win 7 licenses and new hardware (plus, the mono platform was highly attractive). My staff had no Linux experience, but were able to achieve relative competency in about 120 days with the help of AskUbuntu, Stack Overflow, and a few "For Dummies" books. We did employ an Ubuntu consultant for 7 days to provide training and support, but beyond that spent $0.00 on any kind of paid expertise. In regards to my due diligence, I ran a 3 month beta of the freemium-paid-support model with one of our smaller customers, and achieved mediocre results. I'd like to think its because our software is so stable and easy to use that the customer didn't need much paid support, but I suspect that they circumvented the terms of our SLA in the same manner that we did with the move to Ubuntu. Does anyone out there has any thoughts, advice, or experience relevant to the move I'm considering? What worked, what didn't, etc?

  • KDE: How can I select audio output device for mplayer?

    - by grimripper
    I recently installed Kubuntu 13.10 64-bit, and I'm having a problem with selecting audio output device. In Phonon, when I select audio device preference order and press Apply, Amarok and Dragon will immediately switch to the preferred device. VLC and SMplayer are not affected. VLC has its own setting for selecting the output device, but SMplayer remains a problem. It always plays audio on internal audio, and I can't change output to HDMI. How can I select HDMI for SMplayer's audio output device? I don't know if it matters, but when I select HDMI audio in Phonon and click Test, the test sound plays on the internal audio output as well. In the hardware settings tab, the front left and front right test buttons play audio on HDMI. Also, volume up/down buttons affect HDMI volume when SMplayer is focused. This would make sense if I could get SMplayer to play audio over HDMI, but it would be better if the volume keys affected SMplayer's own volume, or the "mplayer2: audio stream" which appears in volume control while mplayer is playing. EDIT: I've recompiled mplayer with alsa support, and can now select the audio output device from SMplayer's settings. Didn't affect the issue with Phonon of course, but it's a suitable workaround.

  • Recommendations for a web-based help system

    - by ggkmath
    Hi Experts, I'm putting together a fairly large GUI. I'm a tech person, but more on the hardware side, not software. I'm wondering what software package would be best suited to enable me to generate a web-based help-system. Preferably it takes care of a lot of coding, allowing me to focus on the content. For example, the user would click on a link in the GUI when they have a question, that brings them to a web-based Help Guide, for example, providing an overview of how to use the GUI, perhaps a searchable index (key-word based index), table of contents, etc, for navigating through the Help Guide. My first thought was to program everything in XHTML using Dreamweaver, but my layout requirements are fairly modest (just figures and text, maybe a few equations), and I'd prefer not to spend a lot of time concentrating on the programming. Was wondering if any software existed that made generating web-based navigatable pages easy to create/publish. Again, I'm not really a programmer, so if there's something obvious out there, I'm probably not aware of it. Any advice much appreciated! Thanks in advance.

  • Data Center Modernization: Harness the power of Oracle Exalogic and Exadata with PeopleSoft

    - by Michelle Kimihira
    Author: Latha Krishnaswamy, Senior Manager, Exalogic Product Management   Allegis Group - a Hanover, MD-based global staffing company is the largest privately held staffing company in the United States with more than 10,000 internal employees and 90,000 contract employees. Allegis Group is a $6+ billion company, offering a full range of specialized staffing and recruiting solutions to clients in a wide range of industries.   The company processes about 133,000 paychecks per week, every week of the year. With 300 offices around the world and the hefty task of managing HR and payroll, the PeopleSoft system at Allegis  is a mission-critical application. The firm is in the midst of a data center modernization initiative. Part of that project meant moving the company's PeopleSoft applications (Financials and HR Modules as well as Custom Time & Expense module) to a converged infrastructure.     The company ran a proof of concept with four different converged architectures before deciding upon Exadata and Exalogic as the platform of choice.   Performance combined with High availability for running mission-critical payroll processes drove this decision.  During the testing on Exadata and Exalogic Allegis applied a particular (11-F) tax update in production environment. What job ran for roughly six hours completed in less than 1.5 hours. With additional tuning the second run of the Tax update 11-F reduced to 33 minutes - a 90% improvement!     Not only that, the move will help the company save money on middleware by consolidating use of Oracle licensing in a single platform.   Summary With a modern data center powered by Exalogic and Exadata to run mission-critical PeopleSoft HR and Financial Applications, Allegis is positioned to manage business growth and improve employee productivity. PeopleSoft applications run on engineered systems platform minimizing hardware and software integration risks.

  • Touchpad stopped working on an Acer AspireOne D255E

    - by Gustavo
    I have a less than a year old Acer AspireOne D255E with a fresh install of Ubuntu 11.10. Everything has been working fine. Great OS and great netbook. But today the touchpad stopped working. It had been working fine. I closed the netbook and when I opened it again, a couple of hours later, I could not move the pointer with the touchpad. I can not get the pointer to move. I cleaned the touchpad surface well, just in case. Everything else is working fine. All the software updates are up-to-date. I have rebooted several times with no solution. I have attached an USB mouse and the pointer works well. What can I do to troubleshoot the problem? I have gone to the System Settings, touchpad section, and there is not much that I can do there. I would like to determine first if it is a hardware or software issue and then how to resolve it. Is there a way that I can reinstall the touchpad drivers. just in case it is a software problem? I have been using Ubuntu for nearly a year now and am very happy with it. Are there any wise Ubuntu gurus out there who can help me? Thank you for reading this note.

  • Cursor seems to freeze in the first attempt of typing - Unity 3D, 12.04

    - by Denis
    It happens in the first attempt of typing, no matter is after the startup, or 5 minutes later, or then after. The cursor (or maybe it's the system) seems to freeze, no matter the application I use, taking up 5 sec to appear what is typed. Subsequently, everything is normal, using another applications. @Anwar Shah suggested it could be a daemon waiting to run before the lauching of the first application. Turning off Zeitgest didn't help. It occurs only with Unity-3d. Tested with Unity-2d, everything is fine. Tried to change some Compiz settings, nothing worked, although not tested with every single parameter. Also I deactivated Ati proprietary driver, no effect. My system: AMD E350 1.6Gh, 2G-Ram, ATI graphics - Ubuntu 12.04, 64bits. Update 1: the cursor is blinking normally before I start typing. After the first character (which is not showed), seems to freeze, taking 5 seconds to get normal again. Very annoying, specially when you want to access login sites. Update 2: I tested on a different and old machine (Athlon 64 4800 x2, 4Gb ram, no problems - takes 2 seconds, acceptable. I think it could be related to my specific hardware (Samsung RV415), but not sure about it. Anyone experiencing something similar? Is that what I should expect, or can be fixed or improved? Thanks.

  • how to create a mirror of minimum size to install Ubuntu

    - by Registered User
    I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like http://bderzhavets.wordpress.com/2008/10/28/install-ubuntu-intrepid-server-pv-domu-at-xen-33-port-via-httpgetco-centos-52-dom0/ the host and client are both going to be my laptop, I Google d and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree.Which is where I have to do this work.So I have to create a URL structure which is similar to Ubuntu mirrors.So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

  • OS choice for functional developing

    - by Carsten König
    I'm mainly a .NET developer so I normaly use Windows/VisualStudio (that means: I'm spoiled) but I'm enjoying Haskell and other (mostly functional) languagues in my spare time. Now for Haskell the windows-support is ok (you can get the Haskell-Platform) but latley I tried to get a basic Clojure/Scheme environment set up and it's just a pain on windows. So I'm thinking about trying out another OS for better tooling and languague support. Of course that leaves me with MacOS or some Linux distribution. I never used MacOS before and of course Linux would be cheaper (free) and I don't think I can parallel-boot MacOS on your normal PC-Hardware (can you?). PLUS: I don't have a clue about the tools you can use on those (to me) forign OSs. To make it short: I want to explore more Haskell, Clojure, Scala, Scheme and of course need at least good tooling for JavaScript/HTML5/Css. Support for .NET/Mono/F# would be great but for this I will still have my Win7 boot. So I like to know: - what is your prefered OS, Distribution (is Ubuntu viable?) - what Editor/IDE are you using Thank you for your help! PS: I'm not sure if this is the right place for this question but I surely hope so - if not please let me know where I should move this to (StackOverflow don't seem to be the right place IMHO)

  • Start frei für die Exadata Community im neuen Look!

    - by Frank Schneede (Exadata Community)
    Endlich ist es soweit! Pünktlich mit dem Start der DOAG Konferenz 2012, die vom 20.11. - 22.11.2012 in Nürnberg stattfindet, geht die Deutsche Exadata Community in völlig neu gestaltetem Outfit an den Start. Sie werden hier regelmäßig über neue Ankündigungen sowie Tipps und Tricks im Umgang mit Exadata informiert. Durch das freiere Blogformat werden an dieser Stelle auch Berichte über Exadata Projekte erscheinen, die besonders hervorhebenswert sind. Ich denke, Sie dürfen gespannt sein! Vieles hat sich seit dem letzten Update in der Community getan, denn auf der diesjährigen Oracle Open World in San Franzisco wurde eine ganze Reihe spannender Ankündigungen rund um Exadata gemacht. Die kürzlich vorgestellten Modelle Exadata Database Machine X3-2 und X3-8 sind in der grundlegenden Architektur zwar unverändert geblieben, jedoch sind die Modelle mit aktuellen Prozessoren in SandyBridge Mikroprozessorarchitektur noch leistungsfähiger als bisher. Der vierfach vergrößerte Flash Cache nimmt wesentlich mehr Daten auf und macht die Exadata so zur "In-Memory" Database Machine. Mit der neuen Exadata Software 11.2.3.2 kann der Flash Cache nun als persistenter Write Back Flash Cache verwendet werden. Durch das neuartige Caching profitieren auch OLTP Applikationen, die eine hohe Last von schreibenden Transaktionen verursachen, stärker von der Exadata Technologie. Ein neues Einstiegsmodell, das Exadata X3-2 Eighth Rack, vervollständigt die Produktfamilie und senkt abermals die Einstiegshürde für die Kunden.  Die beiden Community Tipps zur Exadata Hardware wurden aktualisiert. Lesen Sie alles über die Exadata Database Machine X3-2 und deren große Schwester, die Exadata Database Machine X3-8.

  • Repair ext4 filesystem on USB drive

    - by phineas
    Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

  • Issues in pulse audio in Ubuntu 11.10

    - by Kamal
    Good Morning All. I am a new ubuntu user. So please forgive me if this question is too basic. I have installed Ubuntu 11.10 in my machine. I have logged in as USER_A. My external audio device is a Headset and I was able to hear the audio properly. I need to join my Ubuntu machine to a window's domain (my office server). I followed the steps explained in http://www.ghacks.net/2010/04/21/join-a-ubuntu-machine-to-a-windows-domain/ and was successful in joining my ubuntu machine to the windows domain. sudo apt-get install likewise-open5 sudo domainjoin-cli join DOMAIN USER_B Now when I logged in as USER_B, there is no audio for this user in the same machine. I crossed check with my User_A account. There is no issues with the sound for User_A. Only for User_B, there is no audio. When I checked the sound settings of User_B, there is no device listed in Hardware, Input and Output. Whereas for User A, my Headset is listed in Input and Output. Can anyone please help me on this. Why there is no sound for User_B? Thank you.

  • Sound not working after installing PCI video card and then removing it

    - by bakhshu
    I am running 11.10 on a HP/Compaq Presario sr1010z, and the video/audio was working fine with whatever was in the machine already. Then I installed a new video card (PCI/nVidia), which disabled the audio/video on the old one automatically. But that card didn't work out too well so I removed it. Now the video is back to normal, but the audio is gone. I have tried the following: 1. In BIOS, set audio to on/enable rather than Auto 2. Looked for hardware in System Settings Sound, but nothing shows up there 3. But when I run the sysinfo utility, I get the description of the audio controller When I do a 'sudo aplay -l', I get 'aplay: device_list:240: no soundcards found...' And then when I do a 'lspci -v | grep -A7 -i "audio"' I get the following: 00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] SiS7012 AC'97 Sound Controller (rev a0) Subsystem: Hewlett-Packard Company Device 2a05 Flags: bus master, medium devsel, latency 32, IRQ 5 I/O ports at a000 [size=256] I/O ports at a400 [size=128] Capabilities: 00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.1 Controller (rev 0f) (prog-if 10 [OHCI]) Any ideas on how to fix this?

  • Using EC2 instance as main development platform

    - by David
    My problem I am working as a consultant for various companies. Each company provides me with a laptop where with their software on and I also have my own where I have my development environment. I tend to buy a new laptop every second year and find myself spending lots of time configuring and installing software. I also sometimes spend a lot of time waiting for my laptop to process things. To solve all these issues, I am now considering using EC2 (running windows instances) as my main development platform and just access this from any PC I happen to be at. I calculated that running the High-CPU On-Demand Instances (medium) for 8 hours a day for a year costs me 580$, which is acceptable. I imagine that when I approach the workplace each day, I will make a single click my phone to fire up the instance, so it is ready when I get to work. I should have different icons on my phone to fire up the various instance types. The same software should of course automatically be loaded on the various hardware (sometimes I would even need their instance with 68.4 GB of memory). Another advantage is that if I am having a specific problem with my instance, I could fire up another instance and have someone look into the problem and update the image. My question: Does anyone have experience with such a setup on EC2? What kind of problems do you forsee?

  • Multiple displays using AMD drivers

    - by Halik
    I am currently running a dual display setup with nVidia 8800GTS video card, on a Ubuntu 12.10 box. The current setup uses nVidia TwinView to render the image on a 1920x1200 display and 1600x1200 one. I'm planning to add a third, 1280x1024 display to the setup. The change will require me to upgrade my GFX card to one supporting triple displays. I'll probably go with Sapphire Radeon 7770 (FLEX edition, to avoid additional active DP-DVI adapters). Before I invest in new GFX I wanted to ask - how well the AMD drivers will support such a setup. It does not matter whether it's fglrx or the OSS ones. If I remember correctly, when running Fedora on a Radeon x800, I had 'void' areas above and below the working area on my second display. The desktop was rendered in 1920+1280 width and 1200 height (which left 176px of vertical space accessible for my cursor and windows but not displayed on the screen - I'd prefer to avoid that). It may have very well been my misconfiguration back then. Generally, are there any solutions from AMD on par with TwinView? Or is it a non-issue at all? Also, I'm wondering about the usual stuff - hardware h264 decoding support, glitch-free flash support, any issues with Compiz/Unity?

  • LiveMeeting VC PowerShell PASS – Troubleshooting SQL Server with PowerShell

    - by Laerte Junior
    Guys, join me on Wednesday July 18th 12 noon EDT (GMT -4) for a presentation called Troubleshooting SQL Server With PowerShell. It will be in English, so please make allowances for this. I’m sure that you’re aware that my English is not perfect, but it is not so bad. I will do my best, you can be sure. The registration link will be available soon from PowerShell.sqlpass.org, so I hope to see you there. It will be a session without slides. Just code; pure PowerShell code. Trust me, We will see a lot of COOL stuff.Big thanks to Aaron Nelson (@sqlvariant) for the opportunity! Here are some more details about the presentation: “Troubleshooting SQL Server with PowerShell – The Next Level’ It is normal for us to have to face poorly performing queries or even complete failure in our SQL server environments. This can happen for a variety of reasons including poor Database Designs, hardware failure, improperly-configured systems and OS Updates applied without testing. As Database Administrators, we need to take precaution to minimize the impact of these problems when they occur, and so we need the tools and methodology required to identify and solve issues quickly. In this Session we will use PowerShell to explore some common troubleshooting techniques used in our day-to-day work as s DBA. This will include a variety of such activities including Gathering Performance Counters in several servers at the same time using background jobs, identifying Blocked Sessions and Reading & filtering the SQL Error Log even if the Instance is offline The approach will be using some advanced PowerShell techniques that allow us to scale the code for multiple servers and run the data collection in asynchronous mode.

  • Compiling custom kernel 3.7.x lowlatency on Ubuntu 12.04

    - by FlabbergastedPickle
    All, I have a peculiar problem with trying to compile a lowlatency flavor of the latest 3.7 kernel. I retrieved the prepatched source from the launchpad using bzr, compiled it using the usual make-kpkg using the current config file plus default options for the rest, installed the kernel and booted into it. Everything works except for the fglrx and wl drivers that I had to install in the original 12.04 lowlatency kernel. So, I tried recompiling these and succeeded with both of them (no errors were reported)--wl driver required a minor adjustment to system.h include while latest fglrx 12.11 beta11 (released yesterday, Dec. 3rd, 2012) compiled without the hitch. Yet, when I try to modprobe either module (both having in common the fact that they were built after the kernel, fglrx as a deb, and wl via the usual make/make install), I get "FATAL: no MODULENAME module found" (MODULENAME being either wl or fglrx). The graphic driver watermark shows 3D crossed out and "for testing purposes" (or "unsupported hardware," can't remember), and no fglrx or wl is loaded. More mysteriously, dmesg shows no attempt on kernel's behalf to load the said drivers, even though they are clearly in the right /lib/modules/KERNEL_VERSION folder. How is this possible? Has something fundamentally changed in 3.7 kernel that would prevent modprobing of these? I know that there is driver signing option that was merged recently but as far as I could tell the kernel config file generated by the build process had that disabled. OTOH, while building wl driver, I did get a warning that the driver was not signed... Then again, even if the kernel disallowed loading of those modules, shouldn't dmesg reflect that? Any thoughts on this one are most appreciated.

  • Battery not recognized on my laptop (and it recognizes my laptop as a desktop)

    - by AZorin
    I have installed Ubuntu (both 10.10 and 11.04 pre-release) on my laptop but my battery is not recognized and it is detected as a desktop system rather than a laptop. I have tried to get the output of cat /proc/acpi/battery/BAT1/state but the directory doesn't exist. I have tried another guide to paste the battery info into this directory but it doesn't allow me to do that and says that the directory doesn't exist, even though I'm trying to make it. I tried it in root Nautilus and even on an install of Lubuntu (with a root file manager) but it still failed to budge. I really don't know what to do as I have tried all the guides on the internet that I could find. Is there any way to change the configuration file(s) that detect the internal hardware of the computer. The /proc directory is a temporary RAM directory afaik. Is there a directory where that data is stored permanently and where the RAM reads if you know what I mean? Thanks in advance. AZorin This issue has been reported as bug #764513.

  • Brain picking during job interview

    - by mark
    Recently, I had a job interview at a big Silicon Valley company for a senior software developer/R&D position. I had several technical phone screens, an all day on-site interview and more technical phone screens for another position later. The interviews went really well, I have a PhD and working experience in the area I was applying for yet no offer was made. So far, so good. It was an interesting experience, I am employed, absolutely no hard feelings about this. Some of the interviewers asked really detailed questions to the point of being suspicious about new technologies I have been working on. These technologies are still in development and have not come to market yet. I know some major hardware/software companies are working on this too. I have had many interviews before and based on my former interviewing experience and the impression some of the interviewers left behind, I know now all this company wanted from me is to extract some ideas about what I did in this field. Remember, I am referring to a R&D position, not the standard software developer stuff. Has anybody encountered this situation so far? And how did you deal with it? I am not so much concerned about "stealing" ideas but more about being tricked into showing up for an interview when there is no intension to hire anyway. I am considering refusing technical interviews in the future and instead proposing a trial period in which the company can easily reconsider its hiring decision.

  • Alternative to NV Occlusion Query - getting the number of fragments which passed the depth test

    - by Etan
    In "modern" environments, the "NV Occlusion Query" extension provide a method to get the number of fragments which passed the depth test. However, on the iPad / iPhone using OpenGL ES, the extension is not available. What is the most performant approach to implement a similar behaviour in the fragment shader? Some of my ideas: Render the object completely in white, then count all the colors together using a two-pass shader where first a vertical line is rendered and for each fragment the shader computes the sum over the whole row. Then, a single vertex is rendered whose fragment sums all the partial sums of the first pass. Doesn't seem to be very efficient. Render the object completely in white over a black background. Downsample recursively, abusing the hardware linear interpolation between textures until being at a reasonably small resolution. This leads to fragments which have a greyscale level depending on the number of white pixels where in their corresponding region. Is this even accurate enough? ... ?

  • My cpus are powered down periodically

    I post here because I am using Ubuntu but this is probably an hardware problem. Since I bought my new setup with AMD Athlon(tm) II X4 635 Processor and asus m4a89td pro/usb3 motherboard with ecc ram I have stuttering on videos. I was using ubuntu 11.10 now ubuntu 12.10. Looking at syslog I have found that periodically (I notice only on videos but it happens always) this thing happens: Mar 6 23:36:42 virtual1 kernel: [28564.375548] smpboot: CPU 1 is now offline Mar 6 23:36:42 virtual1 kernel: [28564.380751] smpboot: CPU 2 is now offline Mar 6 23:36:42 virtual1 kernel: [28564.394947] smpboot: CPU 3 is now offline Mar 6 23:36:48 virtual1 kernel: [28569.917021] smpboot: Booting Node 0 Processor 1 APIC 0x1 Mar 6 23:36:48 virtual1 kernel: [28569.928015] LVT offset 0 assigned for vector 0xf9 Mar 6 23:36:48 virtual1 kernel: [28569.928372] [Firmware Bug]: cpu 1, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu Mar 6 23:36:48 virtual1 kernel: [28569.928378] perf: IBS APIC setup failed on cpu #1 Mar 6 23:36:48 virtual1 kernel: [28569.931305] process: Switch to broadcast mode on CPU1 Mar 6 23:36:48 virtual1 kernel: [28569.934255] smpboot: Booting Node 0 Processor 2 APIC 0x2 Mar 6 23:36:48 virtual1 kernel: [28569.945554] [Firmware Bug]: cpu 2, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu Mar 6 23:36:48 virtual1 kernel: [28569.945558] perf: IBS APIC setup failed on cpu #2 Mar 6 23:36:48 virtual1 kernel: [28569.948124] process: Switch to broadcast mode on CPU2 Mar 6 23:36:48 virtual1 kernel: [28569.949644] smpboot: Booting Node 0 Processor 3 APIC 0x3 Mar 6 23:36:48 virtual1 kernel: [28569.960838] [Firmware Bug]: cpu 3, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu Mar 6 23:36:48 virtual1 kernel: [28569.960840] perf: IBS APIC setup failed on cpu #3 Mar 6 23:36:48 virtual1 kernel: [28569.962953] process: Switch to broadcast mode on CPU3 I have: updated bios; tried all (really) bios options; changed ram; changed psu and cpu cooler; tried 3.8.1 kernel. What can I do now? Please help me! Thanks, Mario

  • Best Usage of Multiple Computers For a Developer

    - by whaley
    I have two Macbook Pros - both are comparable in hardware. One is a 17" and the other a 15". The 17" has a slightly swifter CPU clock speed, but beyond that the differences are completely negligible. I tried a setup a while back where I had the 17" hooked up to an external monitor in the middle of my desk with the 15" laptop immediately to the right of it, and was using teleport to control the 15" from my 17". All development, terminal usage, etc. etc. was being done on the 17" and the 15" was primarily used for email / IM / IRC... or anything secondary to what I was working on. I have a MobileMe account so preferences were synced, but otherwise I didn't really use anything else to keep the computers in sync (I use dropbox/git but probably not optimally). For reasons I can't put my finger on, this setup never felt quite right. A few things that irked me was the 15" was way under-utlized and the 17" was overutilized having 2 laptops and a 21" monitor all on one desk actually took up lots of desk space and it felt like I had too much to look at. I reverted back to just using the 17" and the external monitor and keeping the 15" around the house (and using it very sparingly). For those of you who are using multiple laptops (or just multiple machines for that matter), I'd like to see setups that work for you for when you have 2 or more machines that gives you optimal productivity and why. I'd like to give this one more shot but with a different approach than my previous - which was using the 15" as a machine for secondary things (communication, reading documentation, etc. etc).
