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…

Confessions of an Unreal Engine 4 Engineering Firefighter (2018)
Author's Note After Release I'm really blown away by the reception of this article. It has spread far wider than I could have ever imagined. The many comments and discussions it has prompted that essentially confirm what I believe is truth by not just fellow engineers but many

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…

Don’t hire top talent; hire for weaknesses
Design your hiring process to find the right people to strengthen your teams' weaknesses, rather than trying to find the best people. Instead of "how can we find the smartest people?" think about "how can we find the people who will make our team stronger?"

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…

A reading list for new engineering managers
<p>Like many engineers, I got thrown into management without any real guidance. I thought management was just telling people what to do. I thought there wasn’t any real science to it; you just needed to feel your way through it. I was wrong: there’s a whole field of study here, and you can learn a lot by…

Donation page "not compliant with Google Play Policies"
I recently updated Pixel Wheels banner image on Google Play. That triggered a review of the game: shortly after the update I received a message telling me Pixel Wheels was "not compliant with Google Play Policies". What nefarious activity does the game engage in? Sneak on users? Mine bitcoins?

Setting up Starlink
In March, I got an email from SpaceX saying Starlink was available at my address, and I could pre-order. I paid $500 for the equipment, plus $25 for a Volcano Roof Mount, and $99 for the first month of service, and a few weeks later, I got the kit you see in the image above. I was a little too excited about getting…

Everyone is still terrible at creating software at scale

Was the NE2000 really that bad?
Over the last few months I have been on and off digging into the history of early PC networking products, especially Ethernet-based ones. In that context, it is impossible to miss the classic NE2000 adapter with all its offshoots and clones. Especially in the Linux community, the NE2000 seems to have had rather bad…
