    I'm trying to set up wireless on vostro 1520 dell laptop, with latest Ubuntu install.

  • Why does ruby-debug say 'Saved frames may be incomplete'

    - by Chris McCauley
    From time-to-time I get this when a breakpoint is triggered. It looks like stack frames aren't getting saved so I can't step back through the call stack - a real pain. See below for an example --> #0 BatchProcess.add_failure_record(row_id#Fixnum, test#Struct::Test, message#String,...) at line server/processes/batch.rb:309 Warning: saved frames may be incomplete; compare with caller(0). (rdb:1) pp caller ["./server/processes/batch.rb:309:in `run_tests'", "./server/processes/common/generic_process.rb:219:in `each'", "./server/processes/common/generic_process.rb:219:in `run_tests'", "./server/processes/common/generic_process.rb:271:in `run_plan'", "./server/processes/common/corrections.rb:19:in `each_with_index'", "./server/processes/common/generic_process.rb:266:in `each'", "./server/processes/common/generic_process.rb:266:in `each_with_index'", "./server/processes/common/generic_process.rb:266:in `run_plan'", "./server/processes/batch.rb:202:in `run_engine'", "/usr/lib/ruby/1.8/benchmark.rb:293:in `measure'", "./server/processes/batch.rb:201:in `run_engine'", "./server/processes/common/generic_process.rb:88:in `run_dataset'", "./server/processes/batch.rb:210:in `run_dataset'", "/usr/lib/ruby/1.8/benchmark.rb:293:in `measure'", "./server/processes/batch.rb:209:in `run_dataset'", "./server/processes/common/generic_process.rb:159:in `run'", "./server/processes/common/generic_process.rb:158:in `each'", "./server/processes/common/generic_process.rb:158:in `run'", "./server/processes/batch.rb:350:in `run'", "/usr/lib/ruby/1.8/benchmark.rb:293:in `measure'", "./server/processes/batch.rb:349:in `run'", "server/processes/test_runs/run_tests.rb:55:in `run_one_process'", "server/processes/test_runs/run_tests.rb:81"] Any ideas on how to stop this happening?

  • What's the largest (most complex) PHP algorithm ever implemented in a single monolithic PHP script?

    - by Alex R
    I'm working on a tool which converts PHP code to Scala. As one of the finishing touches, I'm in need of a really good (er, somewhat biased) benchmark. By dumb luck my first benchmark attempt was with some code which uses bcmath extensively, which unfortunately is 1000x slower in Java, making the Scala code 22x slower overall than the original PHP. So I'm looking for some meaningful PHP benchmark with the following characteristics: The source needs to be in a single file. I need it to be simple to setup - no databases, hard-to-find input files, etc. Simple text input and output preferred. It should not use features that are slow in Java (BigInteger, trigonometric functions, etc). It should not use exoteric or dynamic PHP functions (e.g. no "eval" or "variable vars"). It should not over-rely on built-in libraries, e.g. MD5, crypt, etc. It should not be I/O bound. A CPU-bound memory-hungry algorithm is preferred. Basically, intensive OO operations, integer and string manipulation, recursion, etc would be great. Thanks

  • PHP shell_exec() - Run directly, or perform a cron (bash/php) and include MySQL layer?

    - by Jimbo
    Sorry if the title is vague - I wasn't quite sure how to word it! What I'm Doing I'm running a Linux command to output data into a variable, parse the data, and output it as an array. Array values will be displayed on a page using PHP, and this PHP page output is requested via AJAX every 10 seconds so, in effect, the data will be retrieved and displayed/updated every 10 seconds. There could be as many as 10,000 characters being parsed on every request, although this is usually much lower. Alternative Idea I want to know if there is a better* alternative method of retrieving this data every 10 seconds, as multiple users (<10) will be having this command executed automatically for them. A cronjob running on the server could execute either bash or php (which is faster?) to grab the data and store it in a MySQL database. Then, any AJAX calls to the PHP output would return values in the MySQL database rather than making a direct call to execute server code every 10 seconds. Why? I know there are security concerns with running execs directly from PHP, and (I hope this isn't micro-optimisation) I'm worried about CPU usage on the server. The server is running a sempron processor. Yes, they do still exist. Having this only execute when the user is on the page (idea #1) means that the server isn't running code that doesn't need to be run. However, is this slow and insecure? Just in case the type of linux command may be of assistance in determining it's efficiency: shell_exec("transmission-remote $host:$port --auth $username:$password -l"); I'm hoping that there are differences in efficiency and level of security with the two methods I have outlined above, and that this isn't just micro-micro-optimisation. If there are alternative methods that are better*, I'd love to learn about these! :)

  • How do I mount an EBS root volume to a windows instance in Amazon EC2

    - by Kyle
    So basically, I created a large windows server for development, and then I created a micro windows server for production. I set up everything how I wanted it on my development server, and then i unmounted the drives, and mounted them to my micro server. Now I'm trying to get back into my large windows development server, and I'm getting the error. Invalid value 'i-4896ce28' for instanceId. Instance does not have a volume attached at root (/dev/sda1) this error pops up when I try to start my large windows server. I've remounted the drives to the large development server, and I still get this message. I'm not really sure what to do, I've read other posts and everyone is giving these almost like command line arguments and talking about other tools, and I really have no clue what any of that means, or where I even have an option to enter any commands without be logged into a specific instance.

  • stress testing opencl/Ati GPU on 12.04

    - by lurscher
    What does people normally use to stress test their GPU on ubuntu 12.04? I tried installing Phoronix Benchmark suite ubuntu .deb but it tries to install freeglu3-dev and at the same time complains about $ phoronix-test-suite benchmark pts/opencl The following dependencies are needed and will be installed: freeglut3-dev This process may take several minutes. Reading package lists... Building dependency tree... Reading state information... freeglut3-dev is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 90 not upgraded. There are dependencies still missing from the system: - OpenGL Utility Kit / GLUT 1: Ignore missing dependencies and proceed with installation. 2: Skip installing the tests with missing dependencies. 3: Re-attempt to install the missing dependencies. 4: Quit the current Phoronix Test Suite process. Missing dependencies action: 4 so even if it is installing freeglu3, it still complains about missing GLUT. You can't win against GLUT it seems So, what does people use for this? i mean, really, because i have tried googling for an hour and it is not paying up Thanks!

  • Increase application performance on Amazon AWS

    - by Honus Wagner
    I've got a client with an MVC v1 (.NET) application running on a micro instance. On this instance, I've got .NET, IIS 7.5, and MS SQL Server 2008 running to handle the application. The client has reported that it is taking nearly 10 seconds to process each request. Even loading the initial login page takes about that long, then logging in takes that long, etc etc. The currently running instance specs are as follows: 615 MB RAM Intel Xenon CPU E5430 @ 2.66GHz 2.78 GHz 64-Bit Is the memory availability the issue? or is it the processing power? I forsee two options: Change to a larget instance Set up a 2-tier architecture with two micro instances Which of these will give the application better performance? Thanks in advance.

  • How to switch sound-drivers, and to which? [AMD] Hudson Azalia Controller

    - by Anders Martini
    System settings/sound does not open, freezes and I have to force close. Speaker symbol with volume control does not open scroll-down menu, and there is no sounds. Many people have problems with Hudson Azalia in Ubuntu, but I found no working solution. I don't really understand much of this, but here are some more details: aplay -l : **** List of PLAYBACK Hardware Devices **** (after running this one, it starts some kind of process that doesn't get any results, and doesn't stop, terminal has to be shut down) lspci -vnn | grep -iA5 audio: 00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Device [1002:9902] Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0444000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel -- 00:14.2 Audio device [0403]: Advanced Micro Devices [AMD] Hudson Azalia Controller [1022:780d] (rev 01) Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, slow devsel, latency 32, IRQ 54 Memory at f0440000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel It seems to me that I'm currently running hda Intel drivers on my AMD Hudson Azalia soundcard.

  • WPA2 authentication fails on Ubuntu 12.04 using Rosewill RNX-N1

    - by user94156
    Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. RNX-X1 works on other systems (including TV); also have 2 of 'em and tried each. Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok. Would appreciate some diagnostic guidance and insight (phrased for a newbie!)

  • Access Amazon Linux EC2 over VNC using Guacamole

    - by Neon Flash
    I have a t1.micro Amazon Linux AMI instance running. Now, I want to access it using VNC so that I get the GUI. I came across Guacamole and the installation instructions for the server side configuration. So, I get it that we need to setup Apache Tomcat on the Linux machine and then install all the required dependencies, edit the configuration files for Tomcat. But, how do I access it from Windows? What is the client side configuration? From what I understood so far, instead of using a VNC Client like TightVNC or VNCViewer, we can use the Web Browser to access the Amazon EC2 instance. I am using Windows 7 as the client. I would like to access the Amazon Linux AMI (t1.micro instance) over VNC so that I get the GUI.

  • WPA2 authentication fails using USB network devices (Linksys and Rosewill)

    - by Greg Youtz
    Decided to reduce the clutter in the house and replace a wired connection with a wireless one on my wife's system using USB network device Rosewill RNX-X1. I can see and connect to unprotected network, but WPA2 authentication repeatedly fails. Tried the same with a Linksys USB network adapter. Both failed to authenticate. Worth noting that I recently switched from Comcast to CenturyLink and so switched routers. The system connected successfully to previous router (Linksys EA4500) using WPA2. Would think it is the router (Actiontec C1000A) but all other devices (TV, iPad, Windows, Blackberry, and Squeezebox) connect ok. Would appreciate some diagnostic guidance and insight (phrased for a newbie!)

  • Ubuntu 12.04 problem with E160 huawei - can't detect the device and freezing system

    - by Matt
    I have just installed 12.04 and plugged in E160 and nothing happened - modem doesn't mount. I have found this solution : Ubuntu does not mount some Huawei devices due to bugs, problems etc. See if these work: 1st option: Connect the USB modem. After 10 seconds, type this in a terminal window: lsusb The output will be like this: Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 004: ID 12d1:140b Huawei Technologies Co., Ltd.

  • Decoupling software components via naming convention

    - by csteinmueller
    I'm currently evaluating alternatives to refactor a drivermanagement. In my multitier architecture I have Baseclass DAL.Device //my entity Interfaces BL.IDriver //handles the dataprocessing between application and device BL.IDriverCreator //creates an IDriver from a Device BL.IDriverFactory //handles the driver creation requests Every specialization of Device has a corresponding IDriver implementation and a corresponding IDriverCreator implementation. At the moment the mapping is fix via a type check within the business layer / DriverFactory. That means every new driver needs a) changing code within the DriverFactory and b) referencing the new IDriver implementation / assembly. On a customers point of view that means, every new driver, used or not, needs a complex revalidation of their hardware environment, because it's a critical process. My first inspiration was to use a caliburn micro like nameconvention see Caliburn.Micro: Xaml Made Easy BL.RestDriver BL.RestDriverCreator DAL.RestDevice After receiving the RestDevicewithin the IDriverFactory I can load all driver dlls via reflection and do a namesplitting/comparing (extracting the xx from xxDriverCreator and xxDevice) Another idea would be a custom attribute (which also leads to comparing strings). My question: is that a good approach above layer borders? If not, what would be a good approach?

  • SATA 3 PCIe Controller working with decreased performance (slower than SATA 2)

    - by V M
    After reading this question about maxing out an SSD I decided to do so myself. My mobo only supports SATA 2 and has two PCIe 2.0 x1 connectors (which promiss up to 500 mb/s). So after some searching I decided to go with this controller from amazon. My Samsung magician benchmark before upgrade (running SATA 2): Now after installing the controller all of the benchmark scores are lower (even though the Samsung Magician app confirms its connected to a SATA 3 port): What can I do to remedy this? Any help is appreciated.

  • fglrx: No matching Device section for instance... found how to fix it?

    - by Lejo
    I have HD 4850 card, Ubuntu 12.10 and installed legacy drivers using makson96 ppa. The issue is, that FGLRX can not detect my device and loads vesa bios. I had the same problem on ubuntu 11.10, 12.04 versions. I want to manually help fglrx find a matching device to load as it shoudld do. It is interesting, why does fglrx search for a device in a PCI:0@1:0:1 Bus? in xorg.cof different bus is indicated: Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

  • Metaphor for task synchronization [closed]

    - by nkint
    I'm looking for a metaphor. A friend of mine taught me to use metaphors from nature, everyday life, math, and use them to design my projects. They can help in creating a better design or better understanding or the problem, and they are cool. Now I'm working on a project with hardware and micro-controllers in C. For convenience, I have decided to use multiple micro-controllers as co-processor units for real-time (the slaves) and a master. This has saved me a lot of headache: I can code the main logic in the master without paying too much attention to super optimizing everything; I don't care if I need some blocking-call; I don't worry about serial communication with the computer. I just send messages to the slaves and they are super fast super in real time. I like my design and it seems to work well. So here are the important concepts that I'm trying capture in the metaphor: hierarchy of processing Not using one big brain but rather several small, distributed brain units using distributed power or resources I'm looking for a good metaphor for this concept of having one unit synchronize the work of all the others. Preferably, the metaphor would come from nature, biology, or zoology.

  • How to get the best LINPACK result and conquer the Top500?

    - by knweiss
    Given a large Linux HPC cluster with hundreds/thousands of nodes. What are your best practices to get the best possible LINPACK benchmark (HPL) result to submit for the Top500 supercomputer list? To give you an idea what kind of answers I would appreciate here are some sub-questions (with links): How to you tune the parameters (N, NB, P, Q, memory-alignment, etc) for the HPL.dat file (without spending too much time trying each possible permutation - esp with large problem sizes N)? Are there any Top500 submission rules to be aware of? What is allowed, what isn't? Which MPI product, which version? Does it make a difference? Any special host order in your MPI machine file? Do you use CPU pinning? How to you configure your interconnect? Which interconnect? Which BLAS package do you use for which CPU model? (Intel MKL, AMD ACML, GotoBLAS2, etc.) How do you prepare for the big run (on all nodes)? Start with small runs on a subset of nodes and then scale up? Is it really necessary to run LINPACK with a big run on all of the nodes (or is extrapolation allowed)? How do you optimize for the latest Intel/AMD CPUs? Hyperthreading? NUMA? Is it worth it to recompile the software stack or do you use precompiled binaries? Which settings? Which compiler optimizations, which compiler? (What about profile-based compilation?) How to get the best result given only a limited amount of time to do the benchmark run? (You can block a huge cluster forever) How do you prepare the individual nodes (stopping system daemons, freeing memory, etc)? How do you deal with hardware faults (ruining a huge run)? Are there any must-read documents or websites about this topic? E.g. I would love to hear about some background stories of some of the current Top500 systems and how they did their LINPACK benchmark. I deliberately don't want to mention concrete hardware details or discuss hardware recommendations because I don't want to limit the answers. However, feel free to mention hints e.g. for specific CPU models.

  • SSD install - what do I need to watch out for when reconfiguring SATA ports?

    - by tim11g
    I installed a Samsung 840 SSD in a Windows 7 machine. It seems to be working fine, but I'm not seeing the expected performance. The AS SSD benchmark gives 76 for read and 138 for write. At the upper left of the benchmark it says "pciide - BAD" and "31K - BAD". I'm assuming the "pciide BAD" means the motherboard (Gigabyte GA-P35-DS4) is configured as IDE emulation and needs to change to native SATA. I don't know what the "31K" refers to. The bios settings look like this: I saw this article that indicates that changing the SATA mode of the boot drive can cause problems (Blue Screen): Error message occurs after you change the SATA mode of the boot drive What is the correct procedure to change the SATA Mode without causing a system failure? Apply the registry change from the MSFT article above first, then reboot and change the SATA mode? Will the SATA mode change in the BIOS affect other drives?

  • How to debug lack of sound in Asus EEE PC

    - by Kalmar
    I have an Asus EEE PC 1225B with fresh Lubuntu 12.04. And no sound. It doesn't seem to be some common problem, so I have to make some research what's up. I tried running alsamixer, so I know I have Realtek ALC269VB with nothing muted unexpectedly. What can I do next to identify and solve the problem?

  • Belarc Advisor (Store Passwords using Reversible Encryption)

    - by Steve
    Hi, I'm using Belarc Advisor to examine my PC. Part of BA is a security benchmark summary, which examines components of windows security and provides a benchmark rating. Two items are marked as Fail: - Store Passwords using Reversible Encryption - Password History Size I have opened the Local Security Settings tool from the Control Panel Administrative Tools, and ensured that the "Store passwords using reversible encryption" setting is enabled. Also, I've set the password history to a number. So I'm a bit miffed about the Fail marks. Any idea why the Fail marks appear? Any clues how I can Pass them? Thanks, Steve.
