More Magic

The European Commission has posted a "call for evidence" on open source for digital sovereignty.

I feel a change is happening in how people produce and (want to) consume software, and I want to give my two cents on the matter.

Recently, a user was asking on IRC why CHICKEN doesn't give proper line numbers for error call traces in the interpreter.

Recently I joined bevuta IT, where I am now working on a big project written in Clojure.

As you may know, I co-maintain the uri-generic egg, together with Ivan Raikov.

We're getting close to a CHICKEN 5 release, so let's take a look at the cool new stuff!

Now that we have covered the most important algorithms, it's time to take a look at the internal data representation of extended numerals.

In this instalment of the blog series, we'll take a look at how string->number and number->string are implemented for bignums.

Now that you understand the basic bignum algorithms, let's look at various tricks to speed up these operations.

This is the second part documenting my journey to add full numeric tower support to CHICKEN core.

Originally, CHICKEN only supported fixnums (small integers) and flonums (floating-point numbers).

The recent trouble at GitHub, both cultural changes within the company and criticism from the community, reminded me how unstable the whole "free as in beer code hosting for the public good" idea really is.

I just submitted a patch to add a statistical profiler to CHICKEN.

Maybe you've noticed the little Flattr icons that I've added at the bottom of each post, and now you're wondering if, and why, you should support my blogging efforts with a donation.

In my earlier post about the garbage collector, I lied a little bit about the data representation that CHICKEN uses.

When you're writing Scheme code in CHICKEN it's sometimes necessary to make a little excursion to C.

One of CHICKEN's coolest features has to be its unique approach to garbage collection.

Today I'd like to talk about how CHICKEN Scheme handles distribution of language extensions (which we call "eggs").

Recently there was a small flame war on the Chicken-hackers mailing list.

I've finally decided to get a proper domain name: http://www.more-magic.net.

Last time I explained how sloppy representations can cause various vulnerabilities.

The two biggest threats to the web are caused by the same underlying mistake.

Today we'll look at an old, experimental DSL of my own design.

Today I'd like to discuss Scheme Regular Expressions (SRE).

After last time's example of SCSS, I'd like to take a look at SXML, another Lispy DSL I'm using in this blog.

Setting up this blog was a good excuse to try out SCSS, which I'd been meaning to do for quite a long time.

Welcome to my renewed website.
