Getting and setting max zIndex with jQuery - Rick... →
After having written some code to do this a few times I created a small plug-in that handles both finding the max zIndex and incrementing it by a specific value on the selected element(s). The latter is probably the more common case – it’s rare that you need to know the highest zOrder but don’t actually need to set it.
Apple's new OS geared for multicore future | Deep... →
That’s because Mac OS X 10.6 begins a longer-term Apple attempt to get ahead by cracking a problem facing the entire computer industry: squeezing useful work out of modern processors. Instead of stuffing Snow Leopard with immediately obvious new features, Apple is trying to adjust to the new reality in which processors can do many jobs simultaneously rather than one job fast.

At the foundation of Amazon’s cloud computing are infrastructure services such as Amazon’s S3 (Simple Storage Service), SimpleDB, and EC2 (Elastic Compute Cloud) that provide the resources for constructing Internet-scale computing platforms and a great variety of applications. The requirements placed on these infrastructure services are very strict; they need to score high marks in the...

Cassandra is a highly scalable, eventually consistent, distributed, structured key-value store. Cassandra brings together the distributed systems technologies from Dynamo and the data model from Google’s BigTable. Like Dynamo, Cassandra is eventually consistent. Like BigTable, Cassandra provides a ColumnFamily-based data model richer than typical key/value systems.

Snow Leopard security - The good, the bad and the... →
Known as ASLR, or address space layout randomization, the measure picks a different memory location to load system components each time the OS is started. While Microsoft has had it implemented since the roll-out of Windows Vista, the analogous protection in Snow Leopard, which went on sale Friday, suffers from a crucial deficiency: It fails to randomize core parts of the OS, including the heap,...
Design in Open Source | Mark Boulton →
It all started last Thursday morning. At Mark Boulton Design, we’re finally getting around to redesigning the studio site, and we’re using Drupal to do it. The whole team is hard at work, but probably none more so than our developer, Tim. As you do, first thing in the morning I was checking out the work been done to date and, typically, I was viewing source.

How to find un-indexed queries in MySQL, without... →
The key is knowing what it really means for a query to “not use an index.” There are two conditions that trigger this — not using an index at all, or not using a “good” index. Both of these set a bit. If either bit is set, the query is captured by the filter and logged. Both of these bits also set a corresponding bit in the protocol, so the TCP response to the client actually says “here comes the...

Extensible Messaging and Presence Protocol →
eXtensible Messaging and Presence Protocol (XMPP) is an open, XML-based protocol originally aimed at near-real-time, extensible instant messaging (IM) and presence information (e.g., buddy lists), but now expanded into the broader realm of message oriented middleware.[1] It remains the core protocol of the Jabber Instant Messaging and Presence technology. Built to be extensible, the protocol has...
a little bit of zeank » JSJaC →
JSJaC is a jabber/XMPP client library written in JavaScript to ease implementation of web based jabber/XMPP clients. For communication with a jabber server it needs to support either HTTP Polling or XMPP Over BOSH (formerly known as HTTP Binding). JSJaC has an object oriented design which should be quite easy to use. Communication is done by using the XML HTTP Request object also refered to as...
XEP-0206: XMPP Over BOSH →
This specification defines how the Bidirectional-streams Over Synchronous HTTP (BOSH) technology can be used to transport XMPP stanzas. The result is an HTTP binding for XMPP communications that is useful in situations where a device or client is unable to maintain a long-lived TCP connection to an XMPP server.
XEP-0124: Bidirectional-streams Over Synchronous... →
This specification defines a transport protocol that emulates the semantics of a long-lived, bidirectional TCP connection between two entities (such as a client and a server) by efficiently using multiple synchronous HTTP request/response pairs without requiring the use of frequent polling or chunked responses.
BOSH →
Bidirectional-streams Over Synchronous HTTP (BOSH) is a transport protocol that emulates a bidirectional stream between two entities (such as a client and a server) by using multiple synchronous HTTP request/response pairs without requiring the use of polling or asynchronous chunking. It is a draft standard of the XMPP Standards Foundation. The related standard XMPP Over BOSH defines how BOSH may...

In Ruby, we have the great fortune to have one major framework (Rails) and a number of minor frameworks that drive innovation forward. One of the great minor frameworks which has been getting a lot of traction recently is Sinatra, primarily because it exposes a great DSL for writing small, single-purpose apps.

“On Rake” by John Barnette →
I’ve been reading a lot of Rakefiles lately, and it’s obvious that the folks writing them think of Rake as An Engine For Encapsulating Tasks. That’s fine, but it’s only part of what Rake can do.

droppy - Nested drop down menus →
Quick and dirty nested drop-down menu in the jQuery styleee. I needed a nav like this for a recent project and a quick Googling turned up nothing that really suited, so droppy was born. It hasn’t been designed with flexibility in mind - if you like what you see, great, integration should be a breeze - otherwise I’d look for something more configurable elsewhere.

TestSwarm, the project that I’ve been working on over the past 6 months, or so, is now open to the public. Mozilla has been very gracious, allowing me to work on this project exclusively.

When PubSubHubbub launched at our Real-Time Stream CrunchUp event last month, pretty much everyone in the audience immediately recognized it as a very cool thing. Basically, it takes any feed and significantly speeds up the time it takes to be found by various sources using new hubs that specifically gather that information. But the biggest fan of it may be the company that employs the two who...

Google Code Blog: Towards a programmable web:... →
Why shouldn’t the web itself be programmable? A programmable web enables one application to be extended by another to create new applications that people haven’t imagined before. This goes beyond mash-ups, which primarily combine data sources together into new views. A programmable web is reactive and relies on Web Hooks for event-driven notification, syncing, chaining, modification,...
