Read the original article at Review: Here Comes Everybody by Clay Shirky
Clay Shirky tells a great story. Here Comes Everybody begins with a case of a lost phone in a taxi cab, and the extraordinary turn of events that led to the owner retrieving it. From photos posted online, to NYPD who were uninterested in following up, to taking it all online. Through that online publicity, the story got picked up by the NY Times and CNN, which put pressure on the police to track down the taxi. It's a great example that illustrates the nuances, both good and bad, powerful and persistent that the Internet can unleash.
Throughout the book he weaves stories about the network effect, friends and friends of friends, and how that impacts information, organization, and the spread …[Read more]

Saw this interesting paper about highly concurrent programming methods and figured the word should be spread! It’s not new material but it’s a good read. See the full article here: http://www.usenix.org/events/hotos03/tech/full_papers/vonbehren/vonbehren_html/
“Highly concurrent applications such as Internet servers and transaction processing databases present a number of challenges to application designers. First, handling large numbers of concurrent tasks requires the use of scalable data structures. Second, these systems typically operate near maximum capacity, which creates resource contention and high sensitivity to scheduling decisions; overload must be handled with care to avoid thrashing. Finally, race conditions and subtle corner cases are common, which makes debugging and code maintenance difficult.
LinuxTag is the most important place for Linux and open source software in Europe. Last year, LinuxTag had over ten thousand attendees, and over 300 speakers. This year, the 16th LinuxTag will be June 9-12, 2010 at the Berlin Fairgrounds in Germany.
LinuxTag seeks exciting and suitable proposals for presentations in the conference tracks. The Call for Papers ends today.
I am proud to be a member of the LinuxTag Program Committee. Although a lot of proposals have already been submitted, there are some topics missing that I’d personally like to see covered. So, if you’re up for a last minute submission, get your inspiration from the following list:
- Is/was the recent economic crisis an …
This is going to be a really short post, but for someone it could save an hour of life.
So, you’ve nothing to do and you’ve decided to play around with IPv6 or maybe you’re happened to be an administrator of a web service that needs to support IPv6 connectivity and you need to make your nginx server work nicely with this protocol.
First thing you need to do is to enable IPv6 in nginx by
recompiling it with
--with-ipv6 configure option and
reinstalling it. If you use some pre-built package, check if your
nginx already has this key enabled by running
The results should have
--with-ipv6 option in
|[root@node ~]# nginx …|
Others have done it, so why shouldn’t I do it, too? Well, usually that’s not my line of thought, but when today I read David Linsin's blog post about his stats I thought I might follow along.
The overall visits to my blog – and countless others with no doubt – display the workday/weekend jagged line one would expect. The summer months seem to be a little lower on average, but that’s ok, people deserve their vacations. Blue line is 2009, green line is 2008 for comparison.
For a lot of log processing, I need to store IP addresses in a database table. The standard process was always to convert it to an unsigned int in perl or php and then insert it. Today I discovered an easier way. MySQL's INET_ATON function. It takes an address in dotted quad format and converts it into an INT. So, all you have to do is this:
INSERT INTO table (ip) VALUES (INET_ATON('$ip_address'));
Coming to the Hyatt Santa Clara, for the MySQL Conference & Expo 2009? Beware, that this year, the in-room Internet just isn’t so peachy.
When you check in, there’s this option of a “Business Plan” that Hyatt sells you - USD$30, for free wired in-room Internet (a $12.95/day value), free breakfast (this includes 15% gratuity, so a $20+ value), a free bottle of water (yes, otherwise its $3.95), and all the local and long distance calls in the US that you’ll need (depending on what you do, YMMV). It seemed like a good deal.
Now, for the benefit of others, which has taken about four days for me to fix. When you’re on this plan, the Hyatt rebates your Internet within an hour or so of you signing up for the deal. This tells their ISP that you’re now not able to get access to anything else, but Port 80 and Port 443 access — yes, SMTP, IMAP, SSH, IRC and all …[Read more]
