  • phpThumb cache problems

    - by Cabeludo
    I'm using phpThumb - the PHP thumbnail generator. 'phpThumb.config.php': $PHPTHUMB_CONFIG['cache_maxage'] = 10; $PHPTHUMB_CONFIG['cache_maxsize'] = 1000; $PHPTHUMB_CONFIG['cache_maxfiles'] = 10; but it does nothing... I've got 108 MB in 922 files... and it keeps growing. Thanks for any suggestions.

  • Cache Auth Tokens (or Caching HTTP headers in General) - Best Practices

    - by viatropos
    I'm using the Ruby GData Library to access Google Docs and I recently got the GData::Client::CaptchaError because I was re-logging in with every request. Reading this post, it recommends not logging in with every request, but caching the authentication token. How do I go about doing that correctly? Google says it expires every 24 hours, and it doesn't seem like I should store it in the session, so what should I do? I'm using Ruby on Rails with all this. Thanks so much

  • "conveyor belt" cache architecture

    - by Andrew Matthews
    I'm producing an application with a few peculiar internal communication characteristics that make the usual suspects for data storage and transport (Qs and RDBMSs) ill-fitted. I'm wondering whether there is a product out there that matches the following characteristics: all data put into it is peristent all reads are delivered out of memory data is universally available data lives where it is most needed data is versioned (nice to have) updates are transactional (I'd like ACID characteristics) data is potentially replicated, but always in sync works on windows is based on or has bindings for .NET is really fast is really robust is redundant is scalable I'm looking at things like Microsoft codename "Velocity", but I am not sure whether it fits all of the above characteristics. Likewise, Memcached is not a perfect fit either. The current version of this app opts for an RDBMS with a signaling system for inter-system sync, but latency is too high and versioning of the DB is a pain. I need all the robustness, but with none of the trade-offs.

  • Needed help with deleting rails cache

    - by WarDoGG
    I have been given a project of editing a website which is coded in RoR. However, the changes which i make in the view file is not visible immediately after a hard refresh but after 15-20 mins, the changes reflect. I am guessing this has something to do with the RoR caching system. Can someone please help me out ? The changes i made are purely HTML based like changing HTML attributes, filenames etc...

  • Why this cache doesn't work using final as modifier

    - by Pentium10
    I have this code to get the Cursor once for this instance, and the Log shows it is called many times although I marked as final. What I am missing? private Cursor getAllContactsCached() { final Cursor c=this.getList(); return c; } getAllContactsCached method should retrieve list once, and the 2nd time it should reuse the final object for return

  • xml cache on iphone

    - by dubbeat
    Hi, Could somebody suggest a technique or class library to read up on for XML Caching on the iphone? The biggest lag in my app is the XML being downloaded from the server. If a user views a screen the xml has to be downloaded and parsed and theres a wait of a few seconds. If they leave the screen and come back to it again they have to wait all over again which is kinda crappy.

  • How to make Windows 7 machine allocate a lot of hard disk cache?

    - by Jian Lin
    I am recording some game play capture (recording playing of PS3 or Wii) using a PC with Windows 7 and Hauppauge 1212 HD Recorder, and I have 4GB of RAM... is there a way to increase the size of Windows 7's hard disk cache size so that writing to the hard drive can be super fast? Since there is at least 1.5GB of RAM not being used, something like allocating 1GB just as hard disk cache, is it possible?

  • Does extra hard drive cache make a difference for streaming video?

    - by johnny
    I am looking at the following two drives for a RAID device, which will be streaming normal things but also a lot of video: Seagate Constellation ES.3 ST4000NM0033 - hard drive - 4 TB - SATA-600 TOSHIBA DT01ACA300 3TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Will the 128 MB cache on the Seagate have an effect in my described scenario, compared to the 64 MB on the Toshiba? If so, what sort of difference can I expect? I'm using a qnap device, if that matters.

  • How much does HDD cache matter with Linux softraid?

    - by Jawa
    I'm in a process of renewing/expanding my disk sets, but not quite sure what kind of disks to get, cache-wise. What difference does disk cache amount of 16/32/64MB do, in capacities of, say, 1/1.5/2TB SATA disks? The disks will be used in a webapp server and in a media workstation, with Linux's softraid in raid-1/raid-5 configurations. Note, that as both purposes are purely for a hobby, the pricetag for a dozen of disks is a big issue.

  • Find and free disk space that is unused but unavailable (due to file system error, etc.)

    - by Voyagerfan5761
    Sometimes I get the feeling that if an app such as μTorrent allocates files on my FAT32-formatted flash drive, but then is killed or crashes (as happens more than a few times a month), that space just disappears from my file system. Whether or not that is the case, sometimes I do get a chill from wondering if I've lost hundreds of MB in available storage due to carelessness or malfunctions. Checking my disk with WinDirStat just makes it worse, because I see the huge "<Unknown>" item at the disk root staring at me, eating up well over a gigabyte. It might be FS inefficiency (due to 32 or 64kb sector/cluster size and a lot of tiny files) or it might be a glitch... Is there a tool I can download and run to check my file system and make sure that there aren't any unused allocated blocks on the disk? I want to make sure I'm not losing any disk space to I/O errors, etc.

  • Why do [flush-8:16] and [jbd2/sdb2-8] occasionally use 99.99% disk IO?

    - by ændrük
    Approximately twice a week, the entire graphical interface will lock up for about 10-20 seconds without warning while I am doing simple tasks such as browsing the web or writing a paper. When this happens, GUI elements do not respond to mouse or keyboard input, and the System Monitor applet displays 100% IOWait processor usage. Today, I finally happened to have GNOME Terminal already open when the problem started. Despite other applications such as Google Chrome, Firefox, GNOME Do, and GNOME Panel being unresponsive, the terminal was usable. I ran iotop and observed that commands named [flush-8:16] and [jbd2/sdb2-8] were alternately using 99.99% IO. What are these, and how can I prevent them from causing GUI unresponsiveness? Here is dumpe2fs /dev/sdb2, if it's relevant.

  • When to use Truecrypt, and when not to?

    - by tm77
    I have about 30 (this number will most likely grow over the next few years to 50 or more) unencrypted laptops that I have been tasked to encrypt (entire drive). These machines will be used off site regularly by my users. These machines are running Windows 7 and XP (about 50/50), but more Windows 7 every month. I have experience with Truecrypt, and have had no issues. It appears to be THE solution for a free solution. My concern with Truecrypt is that my users will have 2 passswords needed to login to their machines. Also, I need to choose to either have 1 password for my organization, or carefully document each machine's password (management nightmare). In my mind, choosing between a managed and a free encryption solution is primarily based on the NUMBER of machines that will be encrypted and supported. Two questions: From a management standpoint, what is the tipping point of users where a managed solution would pay for itself over Truecrypt? What are some good third party solutions? (I will consider Bitlocker, but the price to upgrade Windows 7 licenses is a turn-off) I would love to hear from some admins with experience in supporting encrypted machines in a corporate environment. Many thanks in advance!

  • How to create VHD disk image from a Linux live system?

    - by Federico
    Once more, I have to resort at the experts here at SuperUser, as my other sources (mainly Google ;-)) didn't prove very helpful... So basically, I would like to create a VHD image of a physical disk to be archived/accessed/maybe even mounted in a virtual machine. Now, there are dozens of articles and tutorials on how to do that on the web, but none that meets exactly the conditions I would like to achieve: I would like the destination file to be a VHD image, as Windows 7 can mount it natively, even over the network and many other programs can use it (VirtualBox, ...) The disk I'm trying to image contains a Windows XP install, so in theory, I could use the disk2vhd utility, but I would like to find a solution that doesn't require booting that Windows XP install (ie keep the disk read-only) Thus I was searching for a solution involving some sort of live system (running from a USB stic or the network) However, all the solutions that I've came across either make use of disk2vhd or use the dd command under linux, which does a complete copy of the disk (ie even empty blocks) and does not output a VHD file. Is there a tool/program under Linux that can directly create a VHD file? Or is is possible to convert a raw disk image created using dd to a VHD file, without allocating space for the empty blocks? How would you proceed? As always, any advice or comment is highly appreciated!!

  • CentOS 5.5 installation on disk image

    - by Dima
    Today, in order to install CentOS 5.5 I'm using kickstart script. I would like to install CentOS on different way: Create disk image (using dd command) Create filesystem on this disk image using mkfs.ext3 Install CentOS on this filesystem Make this disk image bootable (using grub-install) Copy the disk image to the physical hard disk (using dd command) I know to do all these items except 3. Is it possible to do it? If yes, how can I install CentOS on the disk image?

  • limit linux background flush (dirty pages)

    - by korkman
    Background flushing in linux happens when either too much written data is pending (adjustable via /proc/sys/vm/dirty_background_ratio) or a timeout for pending writes is reached (/proc/sys/vm/dirty_expire_centisecs). Unless another limit is being hit (/proc/sys/vm/dirty_ratio), more written data may be cached. Further writes will block. In theory, this should create a background process writing out dirty pages without disturbing other processes. In practice, it does disturb any process doing uncached reading or synchronous writing. Badly. This is because the background flush actually writes at 100% device speed and any other device requests at this time will be delayed (because all queues and write-caches on the road are filled). Is there any way to limit the amount of requests per second the flushing process performs, or otherwise effectively prioritize other device I/O?

  • Disallow user from decrypting the startup disk

    - by Blacklight Shining
    When you enable FileVault's full-disk encryption, it asks for the password of each account on the system to allow every user to decrypt the disk. You can simply choose not to have a user enter their password, and they will not be able to decrypt the disk. However, if you create an account after enabling disk encryption, the user is automatically allowed to decrypt the disk. How do I disallow a user from decrypting the startup disk?
