  • How to Make Ubuntu Play MP3 Files

    - by Trevor Bekolay
    Because of licensing issues, Ubuntu is unable to play MP3s out of the box. We’ll show you how to play MP3s and other restricted file formats in about four mouse clicks. The philosophy behind Ubuntu is that software should be free and accessible to all. Whether MP3 and other file formats are free is unclear in many countries, so Ubuntu does not include software to read these file formats by default. Fortunately, it does include a package that installs the most commonly used file formats all at once, including a Flash plugin for Firefox. Note: These instructions are for Ubuntu 10.04. There are small differences for earlier versions of Ubuntu. Play MP3 Files Open the Ubuntu Software Center, found in the Applications menu.   Click on View and ensure that All Software is selected. Type “restricted extras” into the search box at the top-right. Find the Ubuntu restricted extras package and click Install. Enter your password when prompted. Once the install is complete, close out of Ubuntu Software Center, and you’ll be able to play MP3 files! To confirm this, we’ll open up Rhythmbox, found in the Sound & Video section of the Applications menu. Our test MP3 plays with no problems! Note: If Rhythmbox tells you that MP3 plugins are not installed, close Rhythmbox and reopen it. You should not have to install anything extra through Rhythmbox.   Despite this extra step, playing the most common audio and video file formats – including Flash videos on the internet – is simple. All the software comes installed, you just have to teach them how to read your files.

  • Oracle’s AutoVue Enables Visual Decision Making

    - by Pam Petropoulos
    That old saying about a picture being worth a thousand words has never been truer.  Check out the latest reports from IDC Manufacturing Insights which highlight the importance of incorporating visual information in all facets of decision making and the role that Oracle’s AutoVue Enterprise Visualization solutions can play. Take a look at the excerpts below and be sure to click on the titles to read the full reports. Technology Spotlight: Optimizing the Product Life Cycle Through Visual Decision Making, August 2012 Manufacturers find it increasingly challenging to make effective product-related decisions as the result of expanded technical complexities, elongated supply chains, and a shortage of experienced workers. These factors challenge the traditional methodologies companies use to make critical decisions. However, companies can improve decision making by the use of visual decision making, which synthesizes information from multiple sources into highly usable visual context and integrates it with existing enterprise applications such as PLM and ERP systems. Product-related information presented in a visual form and shared across communities of practice with diverse roles, backgrounds, and job skills helps level the playing field for collaboration across business functions, technologies, and enterprises. Visual decision making can contribute to manufacturers making more effective product-related decisions throughout the complete product life cycle. This Technology Spotlight examines these trends and the role that Oracle's AutoVue and its Augmented Business Visualization (ABV) solution play in this strategic market. Analyst Connection: Using Visual Decision Making to Optimize Manufacturing Design and Development, September 2012 In today's environments, global manufacturers are managing a broad range of information. Data is often scattered across countless files throughout the product life cycle, generated by different applications and platforms. Organizations are struggling to utilize these multidisciplinary sources in an optimal way. Visual decision making is a strategy and technology that can address this challenge by integrating and widening access to digital information assets. Integrating with PLM and ERP tools across engineering, manufacturing, sales, and marketing, visual decision making makes digital content more accessible to employees and partners in the supply chain. The use of visual decision-making information rendered in the appropriate business context and shared across functional teams contributes to more effective product-related decision making and positively impacts business performance.

  • Make Windows Position Your Dual Monitors Correctly

    - by Mysticgeek
    If you have a dual monitor setup and each monitor is a different size or height, it can be annoying trying to move the mouse pointer between them. Here is a quick tip that will help make the process easier. Align Monitors In our example, we’re using Windows 7, but the process is essentially the same in all versions, but getting to Display Settings is different. In Windows 7 open the Start menu and type display settings into the search box and hit Enter. In Vista right-click the desktop and click Personalize. Then from the Personalize appearance and sounds menu click on Display Settings. In XP right-click on the desktop and select Properties then in Display Properties click the Settings tab. Now here is where you can change the appearance of your monitors. In this example we have a larger 22” LCD and a smaller 19” and it can be annoying getting the mouse pointer from one to another depending where you are on each monitor. So what you want to do is simply move each display around to a particular height so it’s easier to get the pointer over. For example with this setting we know we’ll have no problem moving the pointer to the other screen at the top of each display.   Of course here you can flip your monitors around, change the display resolution, orientation, etc. If you have dual monitors where one might be larger or set up higher than the other, then this is a great way to get them finely tuned. You will have to play around with the settings a bit to settle on what works best for you.

  • Set App Windows to Always be on Top

    - by Asian Angel
    Sometimes you have a small app or other software that you want to keep topmost but how do you keep it on top without a lot of hassle? If this sounds like your situation then you might want to have a look at OnTop. Before For our example we had four individual apps open…any of the four could easily be on top at the moment. OnTop in Action The exe file for the app comes in a zip file. Simply unzip the file, place it in the Program Files Folder, create a shortcut and you are ready to go. Once you start OnTop you will see a new System Tray Icon…right click to access the Context Menu with a list of currently open apps. We decided to set Winamp to be always topmost first. Note: OnTop detected all three individual sections of our Winamp Player along with the individual monitors running in our Taskbar. Clicking on Paint.NET brought it forward over Firefox and Microsoft Word but Winamp was still sitting on top. Clicking on Microsoft Word next still did not affect Winamp’s topmost status. Nice. As soon as we switched the topmost status to Microsoft Word you can see that it immediately came to the front. One thing that we did note in our tests…the best method for switching topmost status is either to choose a different app or close the app that was topmost. Conclusion OnTop might be considered niche software but if you have an app window that you need to keep on top of other windows then you might want to give this small app a try.

  • Using Dependency Walker

    - by Valter Minute
    Dependency Walker is a very useful tool that can be used to find dependencies of a Portable Executable module. The PE format is used also on Windows CE and this means that Dependency Walker can be used to analyze also Windows CE/Windows Embedded Compact module. On Win32 it can be used also to monitor modules loaded by an application during runtime, this feature is not supported on CE. You can download dependency walker for free here: http://dependencywalker.com/. To analyze the dependencies of a Windows CE/Windows Embedded Compact 7 module you can just open it using Dependency Walker. If you want to check if a specific module can run on a Windows CE/Windows Compact 7 OS Image you can copy the executable in the same directory that contains your OS binaries (FLATRELEASEDIR). In this way Dependency Walker will highlight missing dlls or missing entry points inside existing dlls. Let’s do a quick sample. You need to check if myapp.exe (an application from a third party) can run on an image generated with your Test01 OSDesign. Copy Myapp.exe to the flat release directory of your OS Design. Launch depends.exe and use the File\Open option of its main menu to open the application executable file you just copied. You may receive an error if some of the modules required by your applications are missing. Before you analyze the module dependencies is important to configure Dependency Walker to check DLL in the same folder where your application file is stored. This is needed because some Windows CE DLLs have the same name of Win32 system DLLs but different entry points. To configure the DLL search path select “Options\Configure Module Search Order…” from Depenency Walker main menu. Select “The application directory” from the “Current Search Order” list, select it, and move it to the top of the list using the “Move Up” button. The system will ask to refresh the window contents to reflect your configuration change, click on “Yes” to proceed. Now you can inspect myapp.exe dependencies. Some DLLs are missing (XAMLRUNTIME.DLL and TILEENGINE.DLL) and OLE32.DLL exists but does not export the “CoInitialize” entry point that is required by myapp.exe. The bad news is that MyApp.exe will not run on your OS Image, the good news is that now you know what’s missing and you can add the required modules to your OS Design and fix the problem!

  • /etc/enviorment not being read into PATH variable

    - by Dan
    In Ubuntu the path variable is stored in /etc/enviorment. This is mine (I've made no changes to it, this is the system default): $ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" but when I examine my PATH variable: $ echo $PATH /home/dan/bin:/home/dan/bin:/bin:/usr/bin:/usr/local/bin:/usr/bin/X11 You'll notice /usr/games is missing (it was there up until a few days ago). My /etc/profile makes no mention of PATH. My ~/.profile is the default and only has: if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi This only happens in gnome, not in tty1-6. This is missing from both gnome terminal and when I try to call applications from the applications dropdown. Anyone know what could be causing this? Thanks.

  • Dynamic group membership to work around no nested security group support for Active Directory

    - by Bernie White
    My problem is that I have a number of network administration applications like SAN switches that do not support nested groups from Active Directory Domain Services (AD DS). These legacy administration applications use either LDAP or LDAPS. I am fairly sure I can use Active Directory Lightweight Directory Services (AD LDS) and possibly Windows Authorization Manager to work around this issue; however I am not really sure where to start. I want to end up with: A single group that can be queried over LDAP/LDAPS for all it’s direct members LDAP proxy for user name and password credentials to AD DS Easy way to admin the group, ideally the group would aggregate the nested membership in AD DS. a native solution using freely available components from the Windows stack. If you have any suggestions or solutions that you have previously used to solve this issue please let me know.

  • How do I change OSX package install directory?

    - by Scott
    It drives me nuts that every time I download a binary to run on OSX that it wants to install in system directories. ~/Applications is a perfectly fine place to install and doesn't require blindly authenticating somebody else's binary. Is there a way to change the install directory for packages? On a few I've been able to open the package and edit the plist to install it elsewhere, but that doesn't work universally. I install from source when I can, but it isn't always an option. Is there a good way to force the installer to use ~/Applications?

  • Working with Visual Studio Web Development Server and IE6 in XP Mode on Windows 7

    - by Igor Milovanovic
    (Brian Reiter from  thoughtful computing has described this setup in this StackOverflow thread. The credit for the idea is entirely his, I have just extended it with some step by step descriptions and added some links and screenhots.)   If you are forced  to still support Internet Explorer 6, you can setup following combination on your machine to make the development for it less painful. A common problem if you are developing on Windows 7 is that you can’t install IE6 on your machine. (Not that you want that anyway). So you will probably end up working locally with IE8 and FF, and test your IE6 compatibility on a separate machine. This can get quite annoying, because you will have to maintain two different development environments, not have all the tools available, etc.   You can help yourself by installing IE6 in a Windows 7 XP Mode, which is basically just an Windows XP running in a virtual machine.   [1] Windows XP Mode installation   After you have installed and configured your XP mode (remember the security settings like Windows Update and antivirus software), you can add the shortcut to the IE6 in the virtual machine to the “all users” start menu. This shortcut will be replicated to your windows 7 XP mode start menu, and you will be able to seamlessly start your IE 6 as a normal window on your Windows 7 desktop.   [2] Configure IE6 for the Windows 7 installation   If you configure your XP – Mode to use (Shared Networking)  NAT, you can now use IE6 to browse the sites in the internet. (add proxy settings to IE6 if necessary)                       The problem now is that you can’t connect to the webdev server which is running on your local machine. This is because web development server is crippled to allow only local connections for security reasons.   In order to trick webdev in believing that the requests are coming from local machine itself you can use a light weight proxy like privoxy on your host (windows 7) machine and configure the IE6 running in the virtual host.   The first step is to make the host machine (running windows 7) reachable from the virtual machine (running XP). In order to do that, you can install the loopback adapter, and configure it to use an IP which is routable from the virtual machine. In example screenshot (192.168.1.66).   [3] How to install loopback adapter in Windows 7   After installation you can assign a static IP which is routable from the virtual machine (in example 192.168.1.66)                     The next step is to configure privoxy to listen on that IP address (using some not used port, in example, the default port 8118)   Change following line in config.txt:   # #      Suppose you are running Privoxy on an IPv6-capable machine and #      you want it to listen on the IPv6 address of the loopback device: # #        listen-address [::1]:8118 # # listen-address  192.168.1.66:8118   The last step is to configure the IE6 to use Privoxy which is running on your Windows 7 host machine as proxy for all addresses (including localhost)                             And now you can use your Windows7 XP Mode IE6 to connect to your Visual Studio’s webdev web server.                         [4] http://stackoverflow.com/questions/683151/connect-remotely-to-webdev-webserver-exe

  • Will being a VPN Client interrupt web pages hosted by IIS?

    - by f1gm3nt3d
    We have a dedicated server that is primarily used to host our website. I've been tasked with determining the feasibility of setting up a VPN connection from it to our Internal Network at our offices for a few ease of use purposes. My concern is that if I establish this VPN connection our Website will only be available internally and not to the internet in general. I'm concerned about this because in everything I read the fact is stated that by default all network traffic is routed over the VPN connection when it's established, is this also true for applications such as IIS that are listening for incoming connections? TL;DR Will having a VPN Client up and running cause a problem with server applications that may be listening on the NIC connected to the Internet due to changes that VPN makes in the routing tables?

  • Open source Distributed computing tool

    - by Prasenjit Chatterjee
    I want to set up distributed computing on my Local Area Network consisting a bunch of PCs. Say for the time being each one has the same OS - Windows 7. Is there any opensource tool available so that I can share the resources of these PCs over the LAN and increase the speed of my applications and the memory space. I know that if its a graphics intensive application then, it is not very practical, because the speed of LAN is much slower than Graphics processors. But I only want to share general applications, some basic softwares, Programming language IDEs etc. Can anyone shed some light on it? Thanks in Advance..

  • Multiple Ubuntu Server SSH Connections

    - by Craig Smith
    I'm trialing a ubuntu server 12.04 LTS to replace a Windows Server that I use but I have got a little stuck with SSH I'm currently able to SSH into the server but I need to have multiple persistent SSH connections as I have at least 3 applications that need to run in the server and still be able to access their terminals to issue commands to the applications. At the moment this is fine if I use the physical terminals of the machine as I can just jump between the three terminals I use but remotely doing this is the issue. As I'm not entirely familiar with this side of linux I'm not sure if this is even possible to do or how to even get around this issue.

  • Optimizing Solaris 11 SHA-1 on Intel Processors

    - by danx
    SHA-1 is a "hash" or "digest" operation that produces a 160 bit (20 byte) checksum value on arbitrary data, such as a file. It is intended to uniquely identify text and to verify it hasn't been modified. Max Locktyukhin and others at Intel have improved the performance of the SHA-1 digest algorithm using multiple techniques. This code has been incorporated into Solaris 11 and is available in the Solaris Crypto Framework via the libmd(3LIB), the industry-standard libpkcs11(3LIB) library, and Solaris kernel module sha1. The optimized code is used automatically on systems with a x86 CPU supporting SSSE3 (Intel Supplemental SSSE3). Intel microprocessor architectures that support SSSE3 include Nehalem, Westmere, Sandy Bridge microprocessor families. Further optimizations are available for microprocessors that support AVX (such as Sandy Bridge). Although SHA-1 is considered obsolete because of weaknesses found in the SHA-1 algorithm—NIST recommends using at least SHA-256, SHA-1 is still widely used and will be with us for awhile more. Collisions (the same SHA-1 result for two different inputs) can be found with moderate effort. SHA-1 is used heavily though in SSL/TLS, for example. And SHA-1 is stronger than the older MD5 digest algorithm, another digest option defined in SSL/TLS. Optimizations Review SHA-1 operates by reading an arbitrary amount of data. The data is read in 512 bit (64 byte) blocks (the last block is padded in a specific way to ensure it's a full 64 bytes). Each 64 byte block has 80 "rounds" of calculations (consisting of a mixture of "ROTATE-LEFT", "AND", and "XOR") applied to the block. Each round produces a 32-bit intermediate result, called W[i]. Here's what each round operates: The first 16 rounds, rounds 0 to 15, read the 512 bit block 32 bits at-a-time. These 32 bits is used as input to the round. The remaining rounds, rounds 16 to 79, use the results from the previous rounds as input. Specifically for round i it XORs the results of rounds i-3, i-8, i-14, and i-16 and rotates the result left 1 bit. The remaining calculations for the round is a series of AND, XOR, and ROTATE-LEFT operators on the 32-bit input and some constants. The 32-bit result is saved as W[i] for round i. The 32-bit result of the final round, W[79], is the SHA-1 checksum. Optimization: Vectorization The first 16 rounds can be vectorized (computed in parallel) because they don't depend on the output of a previous round. As for the remaining rounds, because of step 2 above, computing round i depends on the results of round i-3, W[i-3], one can vectorize 3 rounds at-a-time. Max Locktyukhin found through simple factoring, explained in detail in his article referenced below, that the dependencies of round i on the results of rounds i-3, i-8, i-14, and i-16 can be replaced instead with dependencies on the results of rounds i-6, i-16, i-28, and i-32. That is, instead of initializing intermediate result W[i] with: W[i] = (W[i-3] XOR W[i-8] XOR W[i-14] XOR W[i-16]) ROTATE-LEFT 1 Initialize W[i] as follows: W[i] = (W[i-6] XOR W[i-16] XOR W[i-28] XOR W[i-32]) ROTATE-LEFT 2 That means that 6 rounds could be vectorized at once, with no additional calculations, instead of just 3! This optimization is independent of Intel or any other microprocessor architecture, although the microprocessor has to support vectorization to use it, and exploits one of the weaknesses of SHA-1. Optimization: SSSE3 Intel SSSE3 makes use of 16 %xmm registers, each 128 bits wide. The 4 32-bit inputs to a round, W[i-6], W[i-16], W[i-28], W[i-32], all fit in one %xmm register. The following code snippet, from Max Locktyukhin's article, converted to ATT assembly syntax, computes 4 rounds in parallel with just a dozen or so SSSE3 instructions: movdqa W_minus_04, W_TMP pxor W_minus_28, W // W equals W[i-32:i-29] before XOR // W = W[i-32:i-29] ^ W[i-28:i-25] palignr $8, W_minus_08, W_TMP // W_TMP = W[i-6:i-3], combined from // W[i-4:i-1] and W[i-8:i-5] vectors pxor W_minus_16, W // W = (W[i-32:i-29] ^ W[i-28:i-25]) ^ W[i-16:i-13] pxor W_TMP, W // W = (W[i-32:i-29] ^ W[i-28:i-25] ^ W[i-16:i-13]) ^ W[i-6:i-3]) movdqa W, W_TMP // 4 dwords in W are rotated left by 2 psrld $30, W // rotate left by 2 W = (W >> 30) | (W << 2) pslld $2, W_TMP por W, W_TMP movdqa W_TMP, W // four new W values W[i:i+3] are now calculated paddd (K_XMM), W_TMP // adding 4 current round's values of K movdqa W_TMP, (WK(i)) // storing for downstream GPR instructions to read A window of the 32 previous results, W[i-1] to W[i-32] is saved in memory on the stack. This is best illustrated with a chart. Without vectorization, computing the rounds is like this (each "R" represents 1 round of SHA-1 computation): RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR With vectorization, 4 rounds can be computed in parallel: RRRRRRRRRRRRRRRRRRRR RRRRRRRRRRRRRRRRRRRR RRRRRRRRRRRRRRRRRRRR RRRRRRRRRRRRRRRRRRRR Optimization: AVX The new "Sandy Bridge" microprocessor architecture, which supports AVX, allows another interesting optimization. SSSE3 instructions have two operands, a input and an output. AVX allows three operands, two inputs and an output. In many cases two SSSE3 instructions can be combined into one AVX instruction. The difference is best illustrated with an example. Consider these two instructions from the snippet above: pxor W_minus_16, W // W = (W[i-32:i-29] ^ W[i-28:i-25]) ^ W[i-16:i-13] pxor W_TMP, W // W = (W[i-32:i-29] ^ W[i-28:i-25] ^ W[i-16:i-13]) ^ W[i-6:i-3]) With AVX they can be combined in one instruction: vpxor W_minus_16, W, W_TMP // W = (W[i-32:i-29] ^ W[i-28:i-25] ^ W[i-16:i-13]) ^ W[i-6:i-3]) This optimization is also in Solaris, although Sandy Bridge-based systems aren't widely available yet. As an exercise for the reader, AVX also has 256-bit media registers, %ymm0 - %ymm15 (a superset of 128-bit %xmm0 - %xmm15). Can %ymm registers be used to parallelize the code even more? Optimization: Solaris-specific In addition to using the Intel code described above, I performed other minor optimizations to the Solaris SHA-1 code: Increased the digest(1) and mac(1) command's buffer size from 4K to 64K, as previously done for decrypt(1) and encrypt(1). This size is well suited for ZFS file systems, but helps for other file systems as well. Optimized encode functions, which byte swap the input and output data, to copy/byte-swap 4 or 8 bytes at-a-time instead of 1 byte-at-a-time. Enhanced the Solaris mdb(1) and kmdb(1) debuggers to display all 16 %xmm and %ymm registers (mdb "$x" command). Previously they only displayed the first 8 that are available in 32-bit mode. Can't optimize if you can't debug :-). Changed the SHA-1 code to allow processing in "chunks" greater than 2 Gigabytes (64-bits) Performance I measured performance on a Sun Ultra 27 (which has a Nehalem-class Xeon 5500 Intel W3570 microprocessor @3.2GHz). Turbo mode is disabled for consistent performance measurement. Graphs are better than words and numbers, so here they are: The first graph shows the Solaris digest(1) command before and after the optimizations discussed here, contained in libmd(3LIB). I ran the digest command on a half GByte file in swapfs (/tmp) and execution time decreased from 1.35 seconds to 0.98 seconds. The second graph shows the the results of an internal microbenchmark that uses the Solaris libpkcs11(3LIB) library. The operations are on a 128 byte buffer with 10,000 iterations. The results show operations increased from 320,000 to 416,000 operations per second. Finally the third graph shows the results of an internal kernel microbenchmark that uses the Solaris /kernel/crypto/amd64/sha1 module. The operations are on a 64Kbyte buffer with 100 iterations. third graph shows the results of an internal kernel microbenchmark that uses the Solaris /kernel/crypto/amd64/sha1 module. The operations are on a 64Kbyte buffer with 100 iterations. The results show for 1 kernel thread, operations increased from 410 to 600 MBytes/second. For 8 kernel threads, operations increase from 1540 to 1940 MBytes/second. Availability This code is in Solaris 11 FCS. It is available in the 64-bit libmd(3LIB) library for 64-bit programs and is in the Solaris kernel. You must be running hardware that supports Intel's SSSE3 instructions (for example, Intel Nehalem, Westmere, or Sandy Bridge microprocessor architectures). The easiest way to determine if SSSE3 is available is with the isainfo(1) command. For example, nehalem $ isainfo -v $ isainfo -v 64-bit amd64 applications sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu 32-bit i386 applications sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov sep cx8 tsc fpu If the output also shows "avx", the Solaris executes the even-more optimized 3-operand AVX instructions for SHA-1 mentioned above: sandybridge $ isainfo -v 64-bit amd64 applications avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu 32-bit i386 applications avx xsave pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov sep cx8 tsc fpu No special configuration or setup is needed to take advantage of this code. Solaris libraries and kernel automatically determine if it's running on SSSE3 or AVX-capable machines and execute the correctly-tuned code for that microprocessor. Summary The Solaris 11 Crypto Framework, via the sha1 kernel module and libmd(3LIB) and libpkcs11(3LIB) libraries, incorporated a useful SHA-1 optimization from Intel for SSSE3-capable microprocessors. As with other Solaris optimizations, they come automatically "under the hood" with the current Solaris release.
