networking essentials
what is networking essentials and what is really involved in networking essentials? —Preceding unsigned comment added by Michaelchawiya (talk • contribs) 09:14, 3 May 2010 (UTC)

PHP question
Would it be possible to use php to convert a folder full of htm files to mhtml? 82.43.89.71 (talk) 15:22, 3 May 2010 (UTC)


 * Yes, but it might be difficult to do from scratch. PEAR, which you can get from the official PHP distribution site, will greatly assist you with this task.  I think there's a Base-64 PEAR utility, and there is Mail_Mime that can easily create and work with MIME encoding and decoding.  Nimur (talk) 16:24, 3 May 2010 (UTC)
 * Also, I may be jumping the gun on this one, but it seems like you're converting to mhtml to allow some sort of code execution that htm does not allow (obviously). Instead of converting all the files to mhtml, you can add an 'AddType' declaration to your web server's configuration that will parse htm's as mhtml's--rocketrye12talk/contribs 22:33, 6 May 2010 (UTC)

THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU. 8. U.S. GOVERNMENT END USERS. The Covered Software is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" (as that term is defined at 48 C.F.R. $ 252.227-7014(a)(1)) and "commercial computer software documentation" as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Covered Software with only those rights set forth herein. This U.S. Government Rights clause is in lieu of, and supersedes, any other FAR, DFAR, or other clause or provision that addresses Government rights in computer software under this License. 9. MISCELLANEOUS. This License represents the complete agreement concerning subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by the law of the jurisdiction specified in a notice contained within the Original Software (except to the extent applicable law, if any, provides otherwise), excluding such jurisdiction's conflict-of-law provisions. Any litigation relating to this License shall be subject to the jurisdiction of the courts located in the jurisdiction and venue specified in a notice contained within the Original Software, with the losing party responsible for costs, including, without limitation, court costs and reasonable attorneys' fees and expenses. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not apply to this License. You agree that You alone are responsible for compliance with the United States export administration regulations (and the export control laws and regulation of any other countries) when You use, distribute or otherwise make available any Covered Software. 10. RESPONSIBILITY FOR CLAIMS. As between Initial Developer and the Contributors, each party is responsible for claims and damages arising, directly or indirectly, out of its utilization of rights under this License and You agree to work with Initial Developer and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or shall be deemed to constitute any admission of liability.

I think I could come up with a RegEx for that, but my gut feeling is that I shouldn't use RegExes in an XML document. However, I've never manipulated XML files before, so I'm not sure what the beginner-friendly options are (there's a whole manure-load of XML-related modules on CPAN). Ideally, I'd like to use a module that is part of the standard Ubuntu Hardy Heron release, or at least has a .deb package in a standard repository. -- 78.43.60.58 (talk) 16:50, 3 May 2010 (UTC)
 * I can't help you with Perl, but doing it in Python (with the BeautifulSoup XML processor) is straightforward:


 * I'm sure Perl will have any number of equivalent libraries. -- Finlay McWalter • Talk 18:05, 3 May 2010 (UTC)
 * I don't really know python, but what you posted looks like you're simply removing all occurences of "disabled", which is not what I want. -- 78.43.60.58 (talk) 17:50, 5 May 2010 (UTC)


 * Hopefully you have a perl DOM-parser for XML? You need to find a node with the name "something" (possibly with some defined attributes), and remove any _child_ tags named "disabled". Take a look at http://cpansearch.perl.org/src/ENNO/libxml-enno-1.00/html/XML/DOM.html, then check out for example XML::DOM::Node->removeChild Hope you can figure out the rest.

Laptop freezing
I have a Dell Inspiron I bought last year. I forgot which model # but now when I surf the internet, it freezes after 15 min. no matter where I am. I do have McAfee Total Protection and I almost run the Spybot daily. What can I do to fix this? --Reticuli88 (talk) 19:39, 3 May 2010 (UTC)


 * Some questions: What version of Windows are you running?  What browser do you use?  Do you use wired or wireless networking?  Have you tried using a different Web browser instead?  Does the computer freeze after 15 minutes even if you don't have a Web browser open?  Comet Tuttle (talk) 20:42, 3 May 2010 (UTC)


 * The laptop could be overheating. Press F2 during startup to access BIOS and check the temperature of the parts inside your computer (viz. the CPU). Also check the event log for errors: Go to Start --> Run... and type <tt>eventvwr.msc</tt>. Also check the device manager (right-click on My Computer --> Manage --> Device Manager) for driver issues.--Best Dog Ever (talk) 21:28, 3 May 2010 (UTC)

 * Write down the temperatures and Google them. Sorry, but each CPU and motherboard has a different maximum temperature, so it really depends on the make and model of the CPU in your laptop. Some BIOS versions don't show the temperatures, though.--Best Dog Ever (talk) 01:44, 4 May 2010 (UTC)

Blu-ray playback on PC
My computer can play Blu-ray, but it has a (noticable) skip. Can anyone tell me what I'm doing wrong, so that I may try to rectify the issue? Specs Intel Core 2 Duo E4500 (2.2 GHz, 2MB L2) 6GB DDR2 800 500GB HDD, ~70% full Radeon HD3650 (1GB DDR2) Gigabyte Mobo Internal BD-ROM (I think it's 4X) Thanks. If I left something out, ask. Mxvxnyxvxn (talk) 21:36, 3 May 2010 (UTC)


 * What software are you using to play it? 82.43.89.71 (talk) 21:39, 3 May 2010 (UTC)


 * The included PowerDVD (Came with the drive.) Mxvxnyxvxn (talk) 05:10, 4 May 2010 (UTC)


 * That PC spec can certainly handle bluray. I managed to get bluray playback working perfectly with the free player Media Player Classic (you will have to open the VOB? files individually though). This was years ago in the early days of bluray however; I'm sure bluray playback on PCs has come a long way since then. I remember I had to install Nvidia Pure Video so I'm not sure if there's an equivalent for ATI. You can also investigate the Matroska Splitter drivers for HD playback. I stopped caring when I bought a PS3 but that's cheating... Sandman30s (talk) 19:53, 4 May 2010 (UTC)
 * Is your virus scanner checking out the contents of the disk? Also have you got the hardware acceleration turned on? Is you computer doing anything else at the same time? Graeme Bartlett (talk) 22:13, 4 May 2010 (UTC)
