Just wanted to say that I really like the ideas you've expressed on the blog. I've found myself thinking similar thoughts, such as about combining shell, awk, make into one language. Keep it up! I'll add that my ideal "c

Respectfully, actually, I think you missed the point. Linux itself offers a number of powerful features such as namespaces to isolate programs, capabilities that can be dropped, etc., including the User Namespace feature we're discussi

Russ Allbery's investigation [1] into alternative init systems, in the Debian's project to select the best one, also viewed this systemd property in a similar way -- a surprising and unexpected benefit. Systemd's native under

I think systemd needs to do most of the things it does. Russ Allbery's analysis of systemd [1], written as part of Debian's evaluation of whether to switch to systemd, explains the benefits. Journal integration is something that R

Fascinating. It will be wondrous to see if it occurs. It also reminds me of a premise in one of my favorite science fiction novels, Diaspora by Greg Egan. In the story, the characters are monitoring the orbit of a binary star system. The or

It is not equally powerful, but Java's approach is easure. This means that at compile time the language can differentiate List<String> and List<Buffer>, and will type check them correctly, but at runtime the generic type ge

I think you make good points, but I think email works well as a secure group communication system for private organizations, and may improve over time as a federated one. One important benefit of email is that you're not reliant on any

Yes, that's a good point. Red Hat Enterprise Linux is open source software, for example, but many companies still pay for RedHat's support services, because the task of doing for yourself what they do for you can be complicated, e
