  • MySQL reclaim index space after large delete?

    - by cdunn
    After performing a large delete in MySQL, I understand you need to run a NULL ALTER to reclaim disk space, is this also true for reclaiming index space? We have tables using 10G of index space and have deleted/archived large chunks of this data and unsure if we need to rebuild the table in order to decrease the size of the index. Can anyone offer any advice? We are trying to avoid rebuilding the table since it would take quite awhile and lock the table. Thanks!

  • domain screensaver control software

    - by Pec
    I'm looking to buy a screensaver control product with granular control. I have about 2000 workstations which require dozens of different timeout values, lock/not locked on resume settings, different screen saver files (that can be frequently updated depending on department), etc. It's looking to be quite an undertaking accomplishing this with domain group policies so I'm hoping you guys have some suggestions of products to use. Hopefully such products would integrate with AD. Thanks

  • Computer wakes up from hibernation at exctly 3:40am every day

    - by vascoFG
    I'm getting tired of waking up to my computer being turned on, and event log shows that it's waking up everyday at 3:40am and most times won't go back to sleep after the determined 30 minutes (maybe from being in the lock screen?). There are no devices armed for wake, activation timers are disabled and all wake options disabled in the BIOS and energy star 4.0c is enabled (was disabled before but no difference).

  • HP ProLiant DL380 G3 Running Windows Server 2000 has crashed between 6-7:30am for the past 5 days

    - by user109717
    I have a HP ProLiant DL380 G3 running Windows Server 2000 that has been crashing everyday between 6-730am. This started when I changed out a failing hard drive 6 days ago. I have looked at the scheduled tasks which does not have anything pertaining to this issue. Below are the only things I see in the system log and some of the dump files. Can this be a hardware issue if this happens at a certain time frame everyday? Any help is greatly appreciated. Thanks The previous system shutdown at 6:07:55 AM on 2/7/2012 was unexpected.

  • Use of .apply() with 'new' operator. Is this possible?

    - by Premasagar
    In JavaScript, I want to create an object instance (via the new operator), but pass an arbitrary number of arguments to the constructor. Is this possible? What I want to do is something like this (but the code below does not work): function Something(){ // init stuff } function createSomething(){ return new Something.apply(null, arguments); } var s = createSomething(a,b,c); // 's' is an instance of Something The Answer From the responses here, it became clear that there's no in-built way to call .apply() with the new operator. However, people suggested a number of really interesting solutions to the problem. My preferred solution was this one from Matthew Crumley (I've modified it to pass the arguments property): var createSomething = (function() { function F(args) { return Something.apply(this, args); } F.prototype = Something.prototype; return function() { return new F(arguments); } })();

  • How do you create a cbuffer or global variable that is gpu modifiable?

    - by bobobobo
    I'm implementing tonemapping in a pixel shader, for hdr lighting. The vertex shader outputs vertices with colors. I need to find the max color and save it in a global. However when I try and write the global in my hlsl code, //clamp the max color below by this color clamp( maxColor, output.color, float4( 1e6,1e6,1e6,1e6 ) ) ; I see: error X3025: global variables are implicitly constant, enable compatibility mode to allow modification What is the correct way to declare a shader global in d3d11 that the vertex shader can write to, and the pixel shader can read? I realize this is a bit tough since the vertex shaders are supposed to run in parallel, and introducing a shader global that they all write to means a lock..

  • Hekaton – SQL Server’s in-memory database engine

    - by Christian
    Microsoft have just gone public at the PASS Summit in Seattle about a new SQL Server engine that they’re working on which is optimized for high-memory servers – an in-memory OLTP database engine which is built-in to SQL Server rather than a separate entity.  This means that you can move just the performance critical parts of your database to Hekaton. The new engine really pushes the performance boundaries by eliminating as many instructions as possible: Main memory optimized tables which are decoupled from on-disk structures; Everything is lock and latch free; More work is pushed to compile time so your T-SQL code is compiled natively into low-level code. We’re already working with a customer on an early adoption program so expect to hear from us on what we learn about implementing it!   Christian Bolton - MCA, MCM, MVP Technical Director http://coeo.com - SQL Server Consulting & Managed Services

  • Wildcard SSL certificate support in Weblogic

    - by user10139630
    Weblogic by default doesnt validate ssl certificates with wildcard entries. i.e. with cn = *.example.com . The impact of this is any ssl handshake which involves these kind of certificates are by default rejected. A clean resolution for this is to use custom hostname verifier and point the same to use the class weblogic.security.utils.SSLWLSWildcardHostnameVerifier To make this change, Launch WLS console Click on Environment -> Servers on your left Select Admin Server Then go to SSL tab Lock & Edit Scroll down and expand advanced section Here change Hostname verification entry to Custom Hostname Verifier Below in Custom Hostname verifier enter "weblogic.security.utils.SSLWLSWildcardHostnameVerifier" Restart weblogic
