The increasing number of concurrent browser connections

While I was catching up on the development of IE8 I found this over at the IE blog: Read more…

Dear Microsoft, please allow resume of large downloads

Dear Microsoft, when updating to Office 2008 SP1 for Mac I am asked to download a 180 Mb update file. While I appreciate you continuous improvement of software through the release of service packs, I must object to the poor implementation of the automatic update handler. Read more…

Building your own Twitter client with Fluid and jQuery

Like many before me, I was searching (unsuccessfully) for a decent twitter client. There are many, but most seem to be ad sponsored or based on a rather hefty framework like AIR (which by now, I guess, has been silently installed on my computer anyhow). Read more…

Quick site performance improvement

I have been playing with YSlow, Yahoo’s tool for web site profiling, for a while. If you haven’t tried YSlow (which is a Firefox addon to Firebug) I recommend you try it right away. Install the Firebug extension first and then add YSlow. Read more…

Reducing distractions, increasing productivity

In the Soviet Union in 1978…

…soviet dissident Yuri Orlov is sentenced to 7 years hard labor for distributing counterrevolutionary material. Also, some distant, mostly unknown relatives of mine decided to go on the trans-siberian railway. I found the photo album while helping my mom move some stuff in her old basement. Most of the pictures were too blurry but some turned out OK. Read more…

Feature requests for a vocabulary editor

I have been searching for quite a while now and apparently there is a missing piece of software waiting to be made. If you are working with RDF data in any way you have probably created a vocabulary using OWL and/or RDF schema sometime. This works well for all technologists out there but in my world vocabularies should be created by domain experts rather than developers. Domain experts do not know OWL or RDF schema. Read more…

Standards require reference implementations!

First, some people bash Microsoft for not implementing DIS 29500 (OOXML) in Office 2007. Then, someone discovers that OpenOffice 2.4 does not create proper ODF. (Update: The test procedure was wrong). And then, Microsoft announce that a coming Office service pack will add native ODF support to Microsoft Office ahead of OOXML support. And, South Africa appelas OOXML adoption. Will Microsoft Office 2007 become the first Office suite to support ODF?

At the heart of the issue is the lack of reference implementations. ISO is way behind W3C in this area. Could someone please tell ISO that open source reference implementations are an absolute necessity when working with standards for information exchange?

From the W3C technical report development process section 7.4.4:

Preferably, the Working Group should be able to demonstrate two interoperable implementations of each feature.

It is simple really. The benefit of a standard is created when it is used. Open source reference implementations shortens the time to market for everyone implementing the standard in their products and also disambiguate interpretation of the standard specification.

Tim, please tell me you know someone at ISO that can fix the process.

 

 

 

Defining Characteristics of a Successful Software Project

Lately, there has been some really interesting presentations and articles on agile methods and how they fit into the big picture of software development. One that was particularly interesting was Scott Ambler’s 2007 IT Project Success Rates Survey (also see the Javapolis presentation). Read more…

Dear lazyweb, please pimp our balcony

Spring is in the air and it is time to start using the balcony. Currently it is in a state of decay and mainly used to store old furniture. I am out of ideas what to make of it. Can you help? Measurements below.

Does your webserver give HEAD?

In the process of constructing a crawler that finds and checks PDF documents on a website I discovered a lot of sites that don’t return information for HEAD requests. A HEAD request should return the same set of HTTP headers as a normal GET request only without the actual payload.

The typical response seem to be status 500 (internal server error) on a lot of IIS sites. So, now is a good time to check your own sites to see what you get back from a:

curl --head http://www.mysite.com

Microsoft Word 2007/2008 Interoperability

Opening a particular Word 2007 document in Word 2008 can yield this error:

Microsoft word interoperability error message

Seriously? Can’t Microsoft get their own implementations to cooperate better? And this has just been approved as an ISO standard?
