Acaba de terminar la semana en el que mucha gente se auto-inflije castigos a fin de contentar o conseguir el favor de la deidad en la que creen. Es curiosa esta tradición y lo mucho que se sigue por los medios de comunicación. Hay gente capaz de hacerse auténticas animaladas, como clavarse unos clavos en pies y manos o flagelarse la espalda (cuanto más sangrienta quede, mayor y mejor es tu fervor religioso). Luego, a parte de las lesiones....

We'd just released "uboot BJ", introducing blogging and video galleries to uboot. well really a lot of things were far from optimal about the software. lots of bugs but a lot of things which were integration troubles, i.e. one bit of software worked 95% and another software worked 95% and together they worked 0%. today and yesterday sat with smo and went through a whole bunch of software from ..

This post is an analysis of the difference in philosophy between static and dynamic typed languages and the pragmatic ramifications of these philosophical differences. I will use Nil/Null/None-types as basis for the example. The Nil-value is used in OO programming languages to designated a non-assigned value. Any object reference can be nil, which gives it a special role. In effect, Nil is an instance of all types. This is a concept that ca..

Aslak Hellesøy created the …. interesting tool Guatanamo. From the documentation: “Do you have problems maintaining high test coverage? All code is guilty until tested innocent. Send the untested code to Guantanamo!” (that is, delete it) I think this is a very interesting policy, and even though it is too extreme to ever be practical, it reveals an underlying principle: If code doesn’t have tests, it doesn’t have value. Chances are that it ..

I am planning to see if I can do some more work on test automation. I have discovered that I am pretty good at going into existing code bases and adding tests now. In order to practice, and to have something to demonstrate, I would like to find a deserving open source project that I could add some unit tests to. The design of the project doesn’t have to be good.

My newest computer is a Dell XPS thing. It’s a huge monster of a laptop (really a gaming laptop, good for the performance). It comes with external LED lights on the top, sides and bottom. These lights are normally only configurable though a custom program. Since I got the PC, I have been dying to find a way to control these LEDs from a script. Finally, today, I found out how.

Writing my previous post got be thinking about code comments. I have seen a lot of bad comments in my years, and I’d like it to stop! Here are a few examples from the horror cabinet of the world of code comments. Stating the bloody obvious Never, ever, say in comments what the code already says. Ever: class Bar { /** gets the foo of the bar */ public String getFoo() {.

Recently, there has been a discussion about code comments on the pragmatic programmer mailing list: “Should you comment or not? What should be commented?” The one point I haven’t seen expressed succinctly is the following: Given a finite amount of time and a codebase with some … issues (which codebase doesn’t have issues?) what is the most useful thing you could do with your time? How often is the answer “comment more”?

In the book Software for Your Head, Jim McCarthy introduces The Core Protocols (pdf). Even though the book occasionally give off a new-agey feeling with ritualistic interaction, I think the Protocols have a lot of merit. I especially like “the decider protocol” As I see it, the Decider protocol is a basic tool for consensus-based decisions. I think consensus as a tools in misunderstood and underutilized. It is easy to assume that basing dec..

Your exchanging flexibility for velocity in development, for a delay in changing you mind, and it is really a bad notion! … In other terms, constaints are liberating”

OK - so Apple released the new Intel Macs this month and shocked everyone with their amazing speed improvements. But what I noticed is that Apple didn’t create a whole new look for them - essentially, the new line is in the same beautiful package as the iMac G5 and PowerBook. These designs must be very good if Apple is going to stick with them, and as a result, are key turning points in Mac evolution. Does evolutionary theory apply to co..

One of the most profound ideas in lambda calculus, is the Y-operator. I’ve learned the Y-operator at least three times, and every time, I found it extremely hard to understand.

Widgets (or Gadgets) are small applications, which usually provide some kind of visual information or access to a frequently used function. Because widgets are in fact applications, they too can include malicious code. Furthermore, due to the simplicity of legitimate widgets, such as calculators and clocks, they are developed without security in mind. In this presentation, we will explain the three different types of widgets in detail....

Intrusion Analysis has been primarily reserved for network junkies and bit biters.

I will show how entropy, a measure of information content defined by Shannon in 1948, can provide useful ways of organizing and analyzing log data. In particular, we use entropy and mutual information heuristics to group syslog records and packet captures in such a way as to bring out anomalies and summarize the overall structure in each particular data set. I will show a modification of Ethereal that is based on these heuristics,....

The core of the security problem is that most software contains latent bugs, and many of these bug can be exploited by attackers to cause the software to do something undesirable to the victim's computer. To block this threat, one can either use only perfect software (of which there is a shortage :) or use a security system to control what software may and may not do. The problem is that such systems are historically very difficult to use....
