• How to log error queries in mysql?

  - by Kaizoku

  I know that there is general_log that logs all queries, but I want to find out which query has an error, and get the error message. I have tried running an error query on purpose, but it logs as a normal query and doesn't report it with error. Any ideas?

• how to find out which servers are accessing Oracle Internet Directory ?

  - by mad sammy

  Hi, We have a OID which is maintaining data about various users. This OID is being accessed by many weblogic servers. Weblogic servers are getting authenticated using this LDAP, but when a particular server authentication fails it causes authentication process failure for all servers, so we want to track that specific server which is causing this error. Is there any facility to know which servers are using the OID or i would like to know that does OID maintains any LOGs of its usage for security purpose.. Thanks.

• how do i computationally slice an audio file into small samples?

  - by user26700

  i need to cut audio files into small samples of even length. What i need is basically a batch processor for audio which does it, and names the slices numerically. i'm on os x and found Audio Splitter, the shortest possible sample length with it is 1 second though, too long for my purpose. Anyone know an alternative?

• Amazon EC2 Ami recommendations for free tier?

  - by Console

  Amazon web services recently introduced a free tier, where you basically get free stuff to try out AWS and run tiny sites and projects. Basically it's free as long as you remain below a certain limit of bandwidth, disk storage etc. Since going over the limits can quickly become quite expensive (for a hobbyist) I would like some recommendations or suggestions about which AMI's I can run on the free tier, for the purpose of trying out Ruby on Rails and/or Django.

• mpasdlta files -- what are they?

  - by Tmdean

  I noticed a bunch of folders in the root of my hard drive named with a string of hex digits that contain files named with a GUID ending with "mpasdlta.vdm" and "mpavdlta.vdm". From some Googling, I've determined that these files are spyware and virus definition files used by Microsoft Security Essentials. Are these files safe to delete? (Why doesn't Microsoft follow their own guidelines and store application data in the folders intended for that purpose? grumble grumble)

• Why do "ls" in UNIX and "dir" in DOS have different names?

  - by bizso09

  Why do they have different names for the same command, listing a directory? Surely, they could have talked to each other and agreed on one common name, such as for example cd which is the same for both unix and dos. This decision to have different names has created many headaches for developers and users and also increased incompatibility between the two systems. Did they do it on purpose? Then how come "cd" is the same?

• Is there an emoticon to express irony?

  - by Dimitri C.

  I use irony rather often, but in written texts such as email I'm often afraid that it might be misinterpreted by the reader. Therefore I'd like to use an emoticon to make the irony explicit, but I'm not sure which one is most often used for this purpose. Which one would be most suited?

• Can you please explain substitution in RewriteRule

  - by Scott

  I have the following statements in an .htaccess file RewriteCond %{HTTP_HOST} ^myOldDomain\.com$ [NC] RewriteRule ^(.*)$ https://myNewDomaink.com/$1 [R=301,L] It works fine. I basically found some sample code and modified it to my specific purpose. What I don't quite understand is: Why does $1 refer to the the portion of the supplied url after the hostname - where is the documentation for this? There is no backreference in the RewriteCond.

• Immersed versus 'normal' version of chrome

  - by Nanne

  I installed chrome, and now I have 2 ways to open chrome: if I open chrome from the metro-tile menu, I get the full-screen, immersed, windows-8 style chrome. If I start the link I got on my desktop, I get the windowed version. Apart from the fact that I would like to know how I might do that on purpose, I also want to know what's going on so I can use the windowed version (I prefer that for a browser) from all links I have, especially the one in the menu.

• Creating Fedora RPMs with a defined Vendor

  - by user800133

  I would like all of my organizations RPMs to have a vendor defined so we can easily see which of our RPMs are installed. Does anyone know why Fedora says: Do not use these tags: Packager Vendor Copyright http://fedoraproject.org/wiki/How_to_create_an_RPM_package They give no reasoning at all. If not using "Vendor" are there recommendations as to another method that is commonly used for this purpose?

• rdate for Windows 2008

  - by Lars D

  I need a command line tool that adjusts the time of a Windows 2008 server, using an internet clock. The purpose is to adjust the time in a script, when other apps from that script are not running. It is not an option to use the built-in NTP service because that makes some apps on this server fail - note, that this server is used in an industrial environment with no PCs on the network and no Windows update or similar applied. Any idea, anyone?

• Database Snapshots of Mirrored databases affect performance of Principal database?

  - by yrushka

  I have 2 servers set in Mirroring High-safety. One is Principal and another in Mirror. Currently I have 2 snapshots of a Production database (100 GB size) created on Principal server (for no_lock purpose of massive select processes) and 2 snapshots on the mirror server for the same database for reporting purposes. I know snapshots reduce performance of source databases but I am not sure if snapshots from mirror server have any impact on principal server's performance. thanks,

• Windows - How to remotely watch log files

  - by weismat

  I would like to look at some log files solely via the console on a standard Windows 7 machine. The logs are created by schedulded tasks and I find it a hazzle to use VNC for this purpose. What technology should I look at? Powershell, Cygwin via ssh or something else? The log files are written using log4Net - thus there might also be an easy way to reconfigure it to create events or something else for remote display.

• Providing a static IP for resources behind AWS Elastic Load Balancer (ELB)

  - by tharrison

  I need a static IP address that handles SSL traffic from a known source (a partner). Our servers are behind an AWS Elastic Load Balancer (ELB), which cannot provide a static IP address; many threads about this here. My thought is to create an instance in EC2 whose sole purpose in life is to be a reverse proxy server having it's own IP address; accepting HTTPS requests and forwarding them to the load balancer. Are there better solutions?

• The real differences between Red Hat Enterprise Linux (RHEL) and CentOS

  - by w00binda

  I know that "the vast majority of changes made (by CentOS team ndr) will be made to comply with the upstream vendor's re-distribution policies concerning trademarked names or logos" But I'm looking for a way to measure the real differences between RHEL and CentOS. My goal is to demonstrate "scientifically" that is possibile to use CentOS for development and testing purpose and use RHEL in the production environment. Any suggestion? Thanks in advance.

  - by Rupert

  I'm looking to buy some usb sticks which will mainly be used in tech support for the purposes of removing viruses and booting up various OS's.

• Arch linux as a wireless router with a USB modem

  - by orlox

  I'm trying to act as an access point to share the internet I get from a USB modem on arch linux. From what I've seen so far, most of what I've found deals with installing particular distributions like DD-WRT to this purpose, but I haven't been able to find any particular and comprehensive solution. Has anyone done this before? I don't know how relevant it might be, but my wireless card is a broadcom device.
