  Meta tag in HTML header

In server response, we can use response.setHeader() to set the meta information in header of a HTML page. The usage is response.setHeader(name,context); meta is used to simulate the response header of HTTP protocol in HTML page. It should be put between the <head> and </head> tag. 1. <meta name="Generator" content="" > <!--This is to specify the tool which generates this page such as Microsoft FrontPage 4.0 etc --> 2. <meta name="keywords" content=""> <!-- To tel...

  HTTP Streaming and Internet Explorer

In early 2006, Alex Russell posted about a neat hack that the Google Talk team in Gmail use to support Comet in Internet Explorer, a trick which works as far back as IE 5.01. What great news! A reliable way to stream Comet messages to Microsoft’s browsers. If only it were that easy. I have not been alone in the following findings: after connecting the htmlfile ActiveX object as a streaming Comet transport to my Comet server, everything works perfectly for a few messages, but then abruptly...

  Open source code libraries suffer from vulnerabilities

A study of how 31 popular open source code libraries were downloaded over the past 12 months found that more than a third of the 1,261 versions of these libraries had a known vulnerability and about a quarter of the downloads were tainted. The study was undertaken by Aspect Security, which evaluates software for vulnerabilities, with Sonatype, a firm that provides a central repository housing more than 300,000 libraries for downloading open source components and gets 4 billion requests pe...

  Automate Everything

Performing manual, repetitive tasks enrages me. I used to think this was a corollary of being a programmer, but I’ve come to suspect (or hope) that this behaviour is inherent in being human. But being able to hack together scripts simply makes it much easier to go from a state of rage to a basic solution in a very small amount of time. As a side point, this is one of the reasons that teaching the basics of programming in schools is so important. It’s hard to think of any j...

  Subdomain Configuration

Subdomain ConfigurationA subdomain configuration is very similar to a domain name configuration. The only difference is that the subdomain entry is tied to the corresponding domain name lookup. A request for the subdomain (e.g. http://content.websitegear.com) will be routed to a DNS server containing the DNS information for the parent domain (websitegear.com). Once the DNS record for the subdomain is resolved to a particular IP address, the request is sent to the web server listening on that IP ...

  Optimization Tricks used by the Lockless Memory Allocator

With the releasing of the Lockless Memory Allocator under the GPL version 3.0 license, we can now discuss more of the optimization tricks used inside it. Many of these are things you wouldn't want to use in normal code. However, when speed is the ultimate goal, sometimes we need to break a few rules and use code that is a little sneaky.The SlabA slab is a well-known technique for allocating fixed size objects. For a given object size, a chunk of memory is divided up into smaller regions of that ...

  Why I Quit My Job to Start a Tech Company

Back in November of 2006, before NY Mag and TimeOut put startups on the cover, before the “tech bubble”, before Twitter and Foursquare were popular, before working at a startup in NY was considered a reasonable thing to do, I was a private equity investor for a $1.6 billion fund called Quadrangle Group. It was just my third year out of college and I made a little over $250,000. For a Brazilian immigrant who spent most of his childhood kind of worried he would have to do physica...
