Using the switch(true) pattern in JavaScript
The switch true pattern isn't well known but it is incredibly useful. It's not a JavaScript specific pattern, but I use it in almost every single project.

Demystifying programs that create programs, part 1: A disassembler
People appear to enjoy the blog posts about me porting different compilers to OpenBSD . What I would like to do for the next couple of posts beginning with this one is to take a step back and de-complexify these programs. Both the D compiler and the GNU Modula-2 compiler are highly complex pieces of software. But at…

Go HTTPS Servers with TLS
This post is a basic introduction to running HTTPS servers and clients in Go using TLS. It assumes some familiarity with public-key crypto. Feel free to check out my earlier posts about RSA and the Diffie-Hellman Key Exchange ; TLS uses the elliptic-curve version of Diffie-Hellman. I won't be covering how the protocol…

Downloading files from S3 with multithreading and Boto3
Yesterday I found myself googling how to do something that I’d think it was pretty standard: How to download multiple files from AWS S3 in parallel using Python? After not finding anything reliable in Stack Overflow, I went to the Boto3 documentation and started coding. Something I thought it would take me like 15…

Everyone is still terrible at creating software at scale
I have a hunch that once people saw the economic potential of software, they started looking for ways to "scale it up" and we haven't stopped searching yet.

A look at LLVM: comparing clamp implementations
Please note that this is not an endorsement or criticism of either of these languages. It’s simply something I found interesting with how LLVM handles code generation between the two. This is an implementation quirk, not a language issue. Update (April 9, 2021): A bug report was filed and a fix was pushed! The LLVM…

Why do long options start with two dashes? (2019)
Around 1990, Richard Stallman (RMS) and I were writing the GNU C library getopt() and he wanted to extend it to support long (multi-character) option names for user-friendliness. He considered Unix…

Commits are snapshots not diffs (2020)
Git has a reputation for being confusing. Users stumble over terminology and phrasing that misguides their expectations. This is most apparent in commands that “rewrite history” such as git cherry-pick or git rebase. In my experience,…

A Critique of the Open Letter Calling for the Removal of RMS
On March 21, Richard M. Stallman (RMS) announced that he is on the Free Software Foundation (FSF) board of directors again after having resigned in September 2019. Two days later, an open letter condemning RMS as misogynist, ableist, transphobic, intolerant, bigoted, hateful, and dangerous was published. The letter…

Lisp as an alternative to Java (2000)
It turns out my hopes were answered. First, Prechelt published another article that covers Tcl, Python, Perl, and Rexx. Also, Ron Garret (nee Erann Gat) did a follow-up study in which he asked programmers to write Prechelt's test program in Lisp. His results show that the resulting Lisp programs ran faster on average…
