Keeping it Small and Simple


Stuff one-legged, cat-owning, 33-year-old she-males with two kids like

Is it just me or are there too many Stuff X people like blogs popping up? It was (maybe) funny for a while, but I think its time to move on. How about something original, for a change?

It can’t be all that difficult to come up with a new concept that is dumb enough to attract loads of people who will do anything as an excuse not to do the things that they are supposed to be doing.


Web Developer add-on for Firefox 3

Filed under: Software — Tags: , , , — Lorenzo E. Danielsson @ 18:53

I finally got around to installing the Web Developer add-on. Last time I checked, which was a long time ago, it wasn’t yet updated for Firefox 3. Today I was browsing through the extensions site and realized that it has been updated.

If you are a web site designer and/or developer, you might want to have a look at the Web Developer add-on. It adds a toolbar that gives you a bunch of web development related functions. One that I find useful, is the ability to highlight elements, like DIVs. I use that to figure out where my (table-less) layouts go wrong.

On the downside, it adds a huge toolbar. I wish there was a key-binding to quickly hide/unhide it (maybe there is one, but I’m not aware of it).

Good beginner book for learning Python

Filed under: Python Programming — Tags: , , , , , , , — Lorenzo E. Danielsson @ 21:32

If you are completely new to programming take a look at How to Think Like a Computer Scientist. It seems quite good, and starts at the very beginning. It is also available on-line, so you don’t have to run to the bookstore and fork out $$$.

It teaches Python, which I think is a good beginner language. It also teaches programming in general, and you will find that what you learn will help you later if you want to learn other languages. Many people will tell you a lot about which programming language is the best first programming language. I don’t think it matters much really. What is more important is to learn one language and to learn it well.

Of course, there are a lot of other good resources as well. It’s good to have access to as many as possible. Each one will have its strengths and drawbacks.

Once you have got a good understanding of the basics, I recommend Dive Into Python which is also available in the Debian repositories (aptitude install diveintopython).

A difference between men and women

Filed under: Humor, Sex — Tags: , , , — Lorenzo E. Danielsson @ 20:47

Women have “vagina dialogues” where the openly talk about their vaginas.

We men are different. We engage in “cock dialogues” where we talk to our cocks. “Get up you lazy tool! It’s the first time in months that I can have real sex and you want to sleep!”

Why do I doubt God’s existence?

Filed under: Religion — Tags: , , , — Lorenzo E. Danielsson @ 20:12

*sigh* Here we go again. I am responding to this.

Part 1

We know God exists through the things He has made. “Since the creation of the world, invisible realities, God’s eternal power and divinity have become visible, recognized through the things He has made.” (Rom. 1:20)

Hermeneutics. This just establishes the claimed existence of a god by reference to a book. Give us a method for testing the claimed facts.

Often the reason people reject God’s existence is not based on logic, but on emotion.

Care to back this claim up? I, as I have mentioned in several posts, neither deny nor accept the existence of any god. I do not believe in gods, but I am aware of the impossibility of conclusively proving God’s “non-existence”.

Imagine if we turn the statement around: often people claim that God exists based not on logic, but on emotion. That sounds at least as reasonable as the original statement. I am sure that there are a lot of people on both sides that make a lot of emotional claims.

They do not want to believe in God because this would mean they have to keep His commandments.

Another claim without any support whatsoever. There are many non-religious reasons to follow at least some of those commandments. Laws against killing and stealing, for instance, seem to be pretty universal, even in societies that are not Christian. And of course, the Christian church has historically killed people who have questioned its authority.

St. Augustine says: “He who denies the existence of God, has some reason for wishing that God did not exist.”

This is just a quote from one author, who happens to have been a Christian. The quote confuses the words deny and wish. Asking people who don’t believe what their reasons are would quickly refute this claim.

If there was a Big Bang, who caused it? Every cause has an effect, and there cannot be a limitless number of limited causes. Ultimately there must be an uncaused cause. If we have a line of dominoes and they fall down, something must have moved the first one. God is the uncaused cause, the unmoved mover.

Now here is a really interesting question. Now of course, it is fully possible to be an atheist and not believe in the Big Bang theory, but let’s for a moment pretend that every non-believer also is a believer in Big Bang.

It is an unanswered question what was the original energy that caused everything to happen. That could point to a god, but not necessarily. There could be other explanations, including ones that we haven’t even thought of. And if a god was the original source of energy, does that mean that Christians then accept the Big Bang theory? Because if they don’t there is no need to put this argument forward, since a Big Bang initiated by God is still in opposition to biblical claims.

I could go further and ask why this should point to the existence of the Christian god. Why couldn’t the original energy be Thor? Or Jupiter? Or any other god.

Part II

Here the author lists a few “arguments” for the existence of god.

Argument from Design
This is so stupid I don’t even know where to begin. I can’t speak for all atheists, but I have never met an atheist that claims that everything happens “by accident”. The creation of the universe is normally explained as having happened through a series of physical processes. Hardly an accident, in other words. I’m an agnostic, so I’ll be a bit more careful about proclaiming what actually happened, at least I can see conclusive evidence.

Moreover, this has absolutely no bearing on the very determined building of a car in a factory. The car is built because there is a factory there, there are materials and workers, there is a company that has set up operations in order to produce units of car for a purpose (normally sales).

Argument from Dependency
Even if we accept this it in no way establishes the existence of a god. And even if we choose to use this as an argument, in what way does it establish the existence of the Christian god as opposed to any other god?

Argument from Conscience
Many people deny the existence of absolute moral law. And there are many moral absolutists who deny the existence of god. Utilitarians, for instance, believe in an absolute moral law, but are not necessarily religious (although individual utilitarians could be religious).

Pascal’s Wager
This is pretty the argument that C.S. Lewis’ put forward for believing in God. The problem is that what if you genuinely do not believe? Should you still pretend to believe “just in case”? That doesn’t seem reasonable to me. Of course, the Christian church would still want you to, because they are interested in your money.

The Purpose of Life Argument
This whole argument presupposes that there is a purpose of life. Of course, the author does not present any support for that claim. It may well be that it is valuable for people to think that there is a purpose of life. That does not mean that there actually is one.

An mpd clone in Ruby

Filed under: Ruby Programming, Rubygame — Tags: , , , , , , , — Lorenzo E. Danielsson @ 18:02

I was bored, so I decided to write a clone of my music player of choice, the excellent mpd. I also put together a little client, similar to my favorite mpd client, the highly usable mpc.

These are of course watered-down clones that cannot match the original mpd. I wasn’t so much interested in writing an alternative to mdp as just writing something for the fun of it. Feel free to improve upon it.

You will need to have Rubygame installed on the machine that is running the server. There are alternatives that you could look into, but I happen to know Rubygame so I am using it. It is likely that I will at some point experiment with other libraries.

Server/client communication is done via XML-RPC. This makes everything very simple. Again, if you want to practice, you change to some other method for client/server communication (SOAP, your own protocol, or whatever).

Other things you could do include writing a GUI client (I recommend Tk, but Qt4 is also nice, Gtk less so, but at least its Ruby bindings are decent to work with). Or, if you think everything should run in the browser, why not a web client? Of course, you can also add more features. In that case I recommend looking into what mpd supports and try to implement as much of it as possible.

First the server, rmpd:

What I’d like to see on the new WP dashboard

Filed under: Wordpress — Tags: , — Lorenzo E. Danielsson @ 16:34

After having used the new WordPress dashboard for a few hours, the thing that sticks out is information overflow. Don’t get me wrong, as I said in my previous post, I mostly like the new dashboard.

But, I wish each block had an expander so that I could expand/contract it. That way, I would have more control over what information I see at any point in time. Further, it would be nice to be able to re-organize the blocks. The summary block that appears at the very top holds the information that I am least directly interested in. I would have loved to position that block at the very bottom instead.

I don’t know far it is possible to customize the WordPress dashboard. I’ve never wanted to do anything like this before. But now, I think it’s time to look into it a little. WordPress (the software) is open source, so it is simple to modify to your own needs, if you are running your own site, or running it locally. But, at, we cannot modify the code so we have to rely on whatever configuration options the UI gives us.

Moreover, I’ve noticed that the new UI leads to more scrolling. Possibly fewer clicks than before, but more scrolling. Having tags and categories beneath the editor on the Write page is beginning to get frustrating. The natural place to have these would be beside the editor, as before.

Interestingly, the Tags and Categories blocks do have the expanders that are missing on the dashboard.

All in all, the new look and feel is probably a step in the right direction with a few quirks that would need to be fixed. With regard to the things that used to be good and have got worse, there is an old saying: if it ain’t broke, don’t fix it.

2008.04.04 upgrade

Filed under: Wordpress — Tags: , , — Lorenzo E. Danielsson @ 22:27

I guess everybody who blogs here will have noticed already. The first thing I noticed was a new dashboard with more information on it. I like it! Then I noticed that the Write Post page has also changed quite a bit.

It all looks nice. It will take a while to get used to some of the changes, but in the long run I think this will allow us to work with WordPress more efficiently (less page clicks for instance).

Currently my pages timeout frequently and I have to reload a few times, but I hope that is just an “upgrade in process”.

An animated history of American empire
