Or for earthquake-prone areas where the roads may be mostly intact, however the drinking water could be bad.
Of course, that would require having the bike beforehand.

Develop multitasking applications with PHP V5 0

Submitted by Anonymous Coward on Monday August 13 2007, @06:24PM

An anonymous reader writes "Many PHP developers believe that because standard PHP lacks threading capabilities, it's impossible for a practical PHP application to multitask. Not true... PHP doesn't support threading in the way other languages like the Java programming language or C++ do, but the examples in this article show that PHP can exploit in-process multitasking and has more potential for speed-ups than many realize."

Building a (fast) Wikipedia offline reader-> 0

ttsiod writes "An internet connection is not always at hand... I wanted to install Wikipedia on my laptop to be able to carry it along with me on business trips... After trying and rejecting the normal (MySQL-based) procedure, I quickly hacked a much better one over the weekend, using open source tools. Highlights: (1) Very fast searching (2) Keyword (actually, title words) based searching (3) Search produces multiple possible articles, sorted by probability (you choose amongst them) (4) LaTEX based rendering for Mathematical equations (5) Harddisk usage is minimal: space for the original .bz2 file plus the index built through Xapian (6) Orders of magnitude faster to install (a matter of hours) compared to loading the "dump" into MySQL — which, if you want to enable keyword searching, takes *days*. Enjoy!"

visual search engine 1

kwarren writes "I made this search engine that's completely visual (the is no text field to enter any sort of query). It attempts to profile a user based on how they rate certain images, and then find past searches that are most similar and gives related results. A lot of people say it reminds them of that 20q.net game; some times it's shockingly accurate, and sometimes it's unimpressive. It definitely shows improvement — some friends and I were trying to search for random topics, and it was pretty common for irrelevant results the first search, but some times as soon as the second or third search relevant results would appear withing 4 or 5 *ratings*. It checks both positive and negative relationships, and some times seems to have built a category using deductive reasoning. It's a pretty cool idea, but doesn't seem 100% accurate, so I'm putting it here for input and feedback. Thanks! -kpw"

Dmitry Dvoinikov writes "This article discusses the effects that data fragmentation has on the database performance under a mixed load. The experiment on a PostgreSQL database that follows the theoretical part yields some numbers and graphs and shows how bad fragmentation is for I/O and shared buffer pool.

What ever happened to Web engineering? 0

Submitted by Anonymous Coward on Thursday July 26 2007, @04:47PM

An anonymous reader writes "Web pages have become a major functional component of the daily lives of millions of people; you, the Web developer, are in a position to make that part of everyone's lives better. Does it ever occur to you that today's Web developers could learn a thing or two from traditional computer programming? What we have today is a generation of Web designers and developers who are attempting to build increasingly sophisticated Web sites without reference to the best practices of software engineering, which this article explores."
