  • Caching strategies - LRU, MRU, Clock-Pro

    - by golgofa
    I am going to write a bachelor's science work on caching strategies and really, can't find any links to specifications or full descriptions of some of them. Only something like summaries from wikipedia. Please, help with some links on LRU, MRU caching and new-one - Clock Pro. Thanks a lot. All links are very useful for me. The purpose of work - is to compare different cache strategies to get more effiency. It based on WebApplication with ejb 2.0, so algorithm's will be implemented there, espesially in ejbLoad() and ejbFindByPrimarKey(). Also, one of aspects of this application - it will use not common scheme of tables in database - it based on metamodel. So, if you had any experience on this topic, i would be grateful to take some of your knowledge)

  • DTLoggedExec 1.0.0.2 Released

    - by Davide Mauri
    These last days has been full of work and the next days, up until the end of july, will follow the same ultra-busy scheme. This makes the improvement of DTLoggedExec a little bit slower than what I desire, but nonetheless Friday I’ve been able to relase an updated version of the tool that fixes a bug and add a very convenient option to make even more straightforward the creationg of execution logs: [bugfix] Fixed a bug that prevented loading packages from SSIS Package Store [new] Added support for {filename} placeholder in both Data Flow Profiling and CSV Log Provider The added feature allow to generate DataFlow profile logs and CSV logs that has the same name of the package that generated them, es: DTLoggedExec.exec /FILE:”MyPackage.dtsx” /LPA:"FILE=C:\Log\{filename}_{date}_{time}.dtsCSVLog" Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • What's the normal way machine-learning algorithms are integrated into normal programs?

    - by Benjamin Pollack
    I'm currently taking a machine learning course for fun, and the course heavily focuses on Matlab/Octave to write the code. One thing mentioned in the course is that, while Matlab/Octave are great for prototyping, they're very rarely used for production algorithms. Instead, those algorithms are typically rewritten in C++/Python/etc., using appropriate libraries, before reaching customers. Fair enough; I get that. But here's my question: is that done for cultural reasons, for technical reasons, or because there is really no language that provides Matlab/Octave-like fluidity, but in a compiled form that can be linked from C/C++/$MainstreamLanguage? The game industry uses Lua for game logic because it's easy to embed, and vastly superior for expressing things like AI. Likewise, there are Prolog variants for rules-heavy applications, Scheme variants for compilers, and so on. If there's a matrix equivalent language, what is it? If there isn't, why is this field different?

  • Are there any tweaks for fixing the appearance of Eclipse Juno on ubuntu?

    - by agnul
    As we have previously established ;-) running Eclipse on ubuntu is a bit disappointing on the UI side. Things are even worse now that Juno is out. Are there any tweaks specific to Gtk3 and Juno that help make things better? The new UI maybe needs some getting used to, but I'm not convinced. Padding got much worse with all the extra (useless?) space between panes. The gradient on the toolbar looks ugly, the quick search looks like it needs some more polish, the buttons to switch perspectives maybe would look nicer without the quick search bar, tabs are waaay to big. Not sure the color scheme has been fixed since I'm running a modified theme for the sake of old 3.7 (the infamous white on black tooltips)

  • How to identify the client is a search robot?

    - by Yau Leung
    I have built my entire site using AJAX (indeed it's GWT). I have also implemented AJAX crawling proposed by Google. However, after the implementation, I found that neither Yahoo , Bing, nor Baidu implemented that scheme! I'm wondering if there is a way to identify the web client is a search robot. If they are, they will be shown the HTML snapshot I created. It will be best if I can identify them in APACHE level, then I can just do a mod_rewrite. But it's still ok if I can do that in PHP or GWT.

  • What's the difference or purpose of a file format like ELF when flat binaries take up less space and can do the same thing?

    - by Sinister Clock
    I will give a better description now. In Linux driver development you need to follow a specification using an ELF file format as a finalized executable, i.e., that right there is not flat, it has headers, entry fields, and is basically carrying more weight than just a flat binary with opcodes. What is the purpose or in-depth difference of a Linux ELF file for a driver to interact with the video hardware, and, say, a bare, flat x86 16-bit binary I write that makes use of emulated graphics mode on a graphics card and writes to memory(besides the fact that the Linux driver probably is specific to making full use of the hardware and not just the emulated, backwards compatible memory accessing scheme). To sum it up, what is a difference or purpose of a binary like ELF with different headers and settings and just a flat binary with the necessary opcodes/instructions/data to do the same thing, just without any specific format? Example: Windows uses PE, Mac uses Mach-O/PEF, Linux uses ELF/FATELF, Unix uses COFF. What do any of them really mean or designate if you can just go flat, especially with a device driver which is system software.

  • What good free forum engines are out there? [closed]

    - by user1306322
    I'm looking for a forum engine for my website, which will look modern, easy to use and follow lengthy discussions. Most of the times people hear "forum" they imagine unresponsive phpBB with terrible color scheme and unnecessarily huge user info sections (avatar, signature) about 600px high each, which make it impossible to see more than 5 posts on a really big screen. I'd like it to be the other way around with my future forum. Features I'd like to see: Clean, transparent section/thread selection, Must not have "message posted, you will be redirected to wherever" screens, 1-click message posting (captchas are ok, but not the ones that erase the whole post when you mistype), Tree hierarchy for comments to posts

  • How to get rid of crawling errors due to the URL Encoded Slashes (%2F) problem in Apache

    - by user14198
    The Google web crawler has indexed a whole set of URLs with encoded slashes (%2F) for our site. I assume it has picked up the pages from our XML sitemap file. The problem is that the live pages will actually result in a failure because of the Url Encoded Slashes Problem in Apache. Some solutions are mentioned here We are implementing a 301 redirect scheme for all the error pages. This should make the Google bot delete the pages from the crawling errors (no more crashing pages). Does implementing the 301s require the pages to be "live"? In that case we may be forced to implement solution 1 in the article. The problem is that solution 1 will pose a security vulnerability..

  • How will the search rank get impacted if i move my mobile website to a single page application?

    - by rahul
    I have two different versions of my site. A desktop version and a mobile optimised version. That is for the same url the server renders different html for different user agents. I had been using vary header for this scheme as recommended by Google. However, now i want to move the mobile website to a single page application for several reasons. I want to know if google stops seeing anything on my mobile web version but the desktop version continues to work as it is, then how would the search rank be impacted given that mobile web gets more traffic than the desktop version. How would the vary header come jnto play

  • Design pattern: static function call with input/output containers?

    - by Pavlo Dyban
    I work for a company in software research department. We use algorithms from our real software and wrap them so that we can use them for prototyping. Every time an algorithm interface changes, we need to adapt our wrappers respectively. Recently all algorithms have been refactored in such a manner that instead of accepting many different inputs and returning outputs via referenced parameters, they now accept one input data container and one output data container (the latter is passed by reference). Algorithm interface is limited to a static function call like that: class MyAlgorithm{ static bool calculate(MyAlgorithmInput input, MyAlgorithmOutput &output); } This is actually a very powerful design, though I have never seen it in a C++ programming environment before. Changes in the number of parameters and their data types are now encapsulated and they don't change the algorithm callback. In the latest algorithm which I have developed I used the same scheme. Now I want to know if this is a popular design pattern and what it is called.

  • How to delete Analytics property from list in Webmaster Tools?

    - by toxalot
    When I look at the Google Analytics Property page in Webmaster Tools (where you associate a Google Analytics web property with a Webmaster Tools site), I see a list of a bunch of properties with weird names. They are test properties from when we were trying things out years ago. I can't view them or change their name in Analytics because they don't exist there. All their profiles were deleted years ago. Is there a way to remove these from the list in Webmaster Tools? Or, alternatively, a way to view them again in Analytics so I can give them a better name, at least. I know this doesn't matter in the big scheme of things, but I hate clutter.

  • UIDocumentInteractionController in iOS for Whatsapp Integration

    - by Smitha
    I was looking for a way to share my application created files through Whatsapp. I found we can chat using custom URL scheme provided by whatsapp : https://www.whatsapp.com/faq/iphone/23559013. But, to share files of my app, read that I have to use DicumentIntercationController. So, is there any smaple available? Also, when I read about apple docs, it says, "Create an instance of the UIDocumentInteractionController class for each file you want to interact with" (https://developer.apple.com/library/ios/documentation/FileManagement/Conceptual/DocumentInteraction_TopicsForIOS/Articles/PreviewingandOpeningItems.html#//apple_ref/doc/uid/TP40010410-SW1). So is it necessary to create instance for each file? I just want to share the files as and when i receive it through my service to my app. Thanks for the help in advance.

  • Programming languages with extensible syntax

    - by Giorgio
    I have only a limited knowledge of Lisp (trying to learn a bit in my free time) but as far as I understand Lisp macros allow to introduce new language constructs and syntax by describing them in Lisp itself. This means that a new construct can be added as a library, without changing the Lisp compiler / interpreter. This approach is very different from that of other programming languages. E.g., if I wanted to extend Pascal with a new kind of loop or some particular idiom I would have to extend the syntax and semantics of the language and then implement that new feature in the compiler. Are there other programming languages outside the Lisp family (i.e. apart from Common Lisp, Scheme, Clojure (?), Racket (?), etc) that offer a similar possibility to extend the language within the language itself?

  • How to backup a dev & QA folder website structure?

    - by novicePrgrmr
    A site I just became in charge of uses a really simple two folder structure to host the dev site and the QA site. The sites are hosted on the company servers so I just have the sites' folders mapped on my desktop. I would like to run some kind of backup scheme, but I am finding it hard to think of a way to do this effectively. The problem is that we aren't using any revision control software, and since the servers aren't controlled by me, I don't think I will be able to implement anything like that. Or could I? The entire site is static too, so no DB's or anything besides html, images, PDFs, etc.

  • Would you use (a dialect of) LISP for a real-world application? Where and why?

    - by Anto
    LISP (and dialects such as Scheme, Common LISP and Clojure) haven't gained much industry support even though they are quite decent programming languages. (At the moment though it seems like they are gaining some traction). Now, this is not directly related to the question, which is would you use a LISP dialect for a production program? What kind of program and why? Usages of the kind of being integrated into some other code (e.g. C) are included as well, but note that it is what you mean in your answer. Broad concepts are preferred but specific applications are okey as well.

  • Howto make a diff of a bios or backup/ restore all bios settings

    - by sfonck
    Hi, I'm using an Dell M90 Precision Laptop which has a NVidia Quadro FX 2500M graphics card and is running Windows XP. Laptop has been running fine - but a few weeks ago screen went 'white' - restarted computer- bios and startup screens show weird green dots and stripes, normal startup only shows a black screen... only VGA mode works to display something. I've been trying to remove and reinstall the correct drivers downloaded from Dell's website - no solution. I gave up and reinstalled XP - everything was working perfect again. 2 weeks later - again the white screen - tried everything again (flashin new bios also - nothing works) Reinstalled XP - everyhting was working again, so I made a DriveSnapShot of the partition. Today - again the 'white screen'. Ok, no problem ...I was thinking all I needed to do was to restore the DriveSnapShot backup... Few minutes later the backup is restored ... but guess what: video driver does not work correctly... As the DriveSnapShot restored the complete partition, as it was at the time everything was working perfectly, this would mean my driver problems are due to 'settings' in the bios or on the graphics-card itself + these 'settings' can get overridden by doing a new XP-install.... I'm out of options, can somebody help me to find a solution for this problem: Is there some way to backup and restore a bios after seeing some problems? Is there some way to know what is causing this problem like a bios diff utility? Thanks!

  • How can I recover data from a dmg that cannot mount?

    - by Benjamin Lee
    I backed up a hard drive in a dmg, then reformatted the hard drive. (I had deleted the efi partition before which was preventing me from reinstalling the operation system). When I tried use the restore function in disk utility it gave an input/output error. I get this error with anything I do to the image including mounting, converting, attaching, verifying, scanning, and getting info through hdiutil imageinfo. I have run all of these with hdiutil and the -noverify, -nomount, and -ignorebadchecksums flags. When I copy the image onto another disk/partition I get a different error: something like "No filesystem". I cannot repair the image with disk utility or asr, which both throw the I/O error. When I put the -verbose flag on the command I actually get a different error: "hdiutil: attach failed - No child processes". I have output from both the -verbose and -debug flags but it is fairly long so I had to attach a link to avoid the 3000 character limit. No recovery system can get the data because it is both compressed and unmountable. How can I get the data back, and what has gone wrong? -debug -verbose

  • Recover files from corrupt filesystem

    - by Emile 81
    My situation: I have an older 80GB IDE internal hdd, with a few files on that I would like very much to recover: some word documents some latex documents (text files) and pictures (png, jpg, eps files) some other text documents and visual studio project files I had backed them (not the latex ones though) up using svn, but have not committed lately, and would loose a lot of work if I cant recover. the hdd seems to have lost its filesystem, i have no idea how it came about. I know it has/had 3 NTFS partitions, i know the files i want are on the second or third partition. I read http://superuser.com/questions/81877/recover-hard-disk-data Partition Find and Mount did not see all the partitions using intelligent scan TestDisk does (i think), I followed the step by step instructions here, but when I try to list the files it says: "Can't open filesystem, filesystem seems damaged." I'm not sure how to proceed here, as TestDisks wiki does not contain this error message afaik. I don't know if the hdd is gonna fail, or some prog has caused the filesystem to be corrupt, the hdd doesnt make a sound, so i guess that's good. I would like some guidance so I don't accidentally cause more damage. (eg. is it ok to let testdisk write the filesystem to disk? I'm pretty the partitions are listed ok, but not 100%)

  • Why does my dd backup of MacBook OS X fail to boot upon restore?

    - by James
    I created a backup of a MacBook hard drive (WD2500BEVS-88US) by hooking it up as a secondary drive on my linux system (Ubuntu 10.10). I used the following command: sudo dd if=/dev/sdc of=/home/backup.img bs=2M This appears to have completed with no errors. I noticed that the file is only 68 GB in size even though the drive is 250 GB in capacity. I restored the image to a spare drive (WD2500BEVS) with the following command: sudo dd if=/home/backup.img of=/dev/sdb bs=2M When I boot the spare drive in the Mac, it appears to start up for a few seconds and then shuts down. (It does not appear to load into the OS at all). When I open up the drive that won't boot in GParted, it looks like this: When looking at the information for the middle partition with the little red exclamation mark, it shows this: The original hard drive that boots ok shows up like this: Further info on both drives: sudo fdisk -l Disk /dev/sdb: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 30402 244198580 ee GPT WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'!

  • Windows 7 AIK help

    - by microchasm
    I've just got in a few Windows 7 (64, Windows 7 Professional) machines, and I'm trying to get the AIK 2010 working. I've set up one of the machines, and installed AIK and MDT on it. I've followed the directions at http://technet.microsoft.com/en-us/library/dd349348%28WS.10%29.aspx about 3 times now, and also tried the built-in .chm help files that came with AIK. In AIK I grab the install.wim image off the OEM cd, at which point it asks me which version (I select Professional). I follow the rest of the instructions creating a new Autounattend answer file, and fill in the various bits and pieces according the the step-by-step guides. I verify the Answer file (No warnings or errors), save it, and copy it onto a USB drive. I go to another machine, insert it's OEM Win7 Disk, and power on. I've set BIOS to boot from CD, so it goes directly into the installation. Once The files are loaded, and Setup starts, it immediately asks which version to install (Home basic, Home Premium, Professiona, Ultimate). Ugh, I thought it was supposed to be an automated install, and that selecting the Version when opening the .wim file would answer this question. I looked for an option to set which version to be installed on the net, in the help, and in AIK itself; to no avail. Anyway, just for laughs I select Professional,and hit continue. It copies files for about 10 seconds, then fails with the following error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information. [OK]". Clicking OK reboots the box, and obviously there are no log files because the OS isn't installed. It is a Dell Optiplex 380 , Intel Core Duo 2.93 GHzl 4 GB RAM, 64 Bit. Any help would be REALLY appreciated.

  • Triple boot WIndows 7, Windows 8, and Mountain Lion on Macbook Pro

    - by Nathan
    Ok, So I have a bit of a unique situation here I could use some help on. I've modded my summer 2011 MBPro to have 2 harddrives by replacing the optical drive. OSX Mountain Lion is installed on a single partition of a 120GB SSD. The second drive is 750GB, partitioned as 550GB, 150GB, and ~50GB. I've set the 550GB to act as my OSX homefolder, but I'd like to install windows 7 and Windows 8 on the remaining partitions. It Took a while, but by following this guide, I eventually found a way to install Windows without a CD/DVD drive by following this http://huguesval.com/blog/2012/02/installing-windows-7-on-a-mac-without-superdrive-with-virtualbox/ It worked flawlessly for creating both windows 7 and windows 8 images that I could clone onto FAT32 partitions. However, I have encountered a problem when trying to triple boot. After I put Windows 8 onto the ~50GB partition and tried to boot into windows 7 I get an error that says something like: error: 0x0000000e The Boot selection failed because the required device is inaccessible. If I re-clone the windows 7 image onto the drive and select the option to "replace BCD" file for the drive, windows 7 will boot but windows 8 now gives me the same exact error. I realize this is a pretty extensive setup, but if anyone has some insight I'd love to hear it.

  • Update to Lion, Cannot boot into Bootcamp partitions, but can use in Parallels

    - by Jon Jester
    Using Snow Leopard had boot camp partitions for both XP and Windows 7. These were both accessible through Parallels 7 or through direct boot through boot camp. Each is on a separate partitioned hard drive. Upgraded to Lion, both were still accessible through Parallels, but have not been able to directly boot into either. Unfortunately is important to me to be able to boot into a least the Windows 7 partition. Have tried virtually everything I can find online. Seen similar issues, but nothing where they were usable virtually but not directly. Nothing works. reFit, correcting the master boot records in Windows with command line, have wiped the Windows 7 partition clean and reinstalled Windows 7 several times 1st using Boot Camp4 drivers then using Boot Camp3 drivers. Have tried resizing the bootcamp partitions. When booting into the Boot Camp partitions directly will go all the way to seeing the desktop before it fails, where I get a Windows error screen. I can see all the disks and their appropriate partitions both in OS X disk utility as well as the Windows installer utility.
