Difficult math is about recognizing patterns
Jeff Bezos tells a great story about the smartest guy he knew at Princeton. He and a classmate were working on a really tough partial differential equation and getting nowhere. They spent 3 hours on the problem and gave up.

When zero cost abstractions aren't zero cost
Rust is built around the concept of “zero cost abstraction”. The idea is that you can write human-friendly high level code and the compiler will give you for free performance at least as good as any optimized low level code you could have written yourself. With zero cost abstraction, you no longer have to trade off…

Beyond coupling and cohesion: strategies for un-fucking yourself
This post belongs in the ‘highly speculative’ category. It contains ideas that I’ve yet to flesh out and properly pin down. Reader beware!

Apple’s Mistake

Bloom Filters: More than a space-efficient hashmap
A bloom filter is one of those data structures you are probably already aware of, or have at least heard about. For those looking for a simple recap, they are a probabilistic data structure which can …

Apps Getting Worse
Too often, a popular consumer app unexpectedly gets worse: Some combination of harder to use, missing features, and slower. At a time in history where software is significantly eating the world, this is nonsensical. It’s also damaging to the lives of the people who depend on these products.

Imaging Cygnus a at 8.45 GHz with ATA
Earlier this year, I published a post showing our results of the interferometric imaging of Cassiopeia A and Cygnus A at 4.9 GHz with the Allen Telescope Array . Near the end of July, I decided to perform more interferometric observations of Cygnus A at a higher frequency, in order to obtain better resolution. I chose…

Revisiting Prechelt’s paper comparing Java, Lisp, C/C++ and scripting languages
In 1999, Lutz Prechelt published a seminal article on the COMMUNICATIONS OF THE ACM (October 1999/Vol. 42, No. 10) called Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences , henceforth Java VS C , which seems to have later (March 2000) been expanded into a full paper, An empirical comparison…

Constexpr is a Platform (2020)
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution. In both cases you restrict yourself to the subset of C++ that works on your target platform, use conditional compilation if your code…

Screw You, Microsoft Edge

I closed a lot of browser tabs
I am widely admired at work for my ability to have many, many browser tabs open. (That, at least, is what I take from the frequent shouts of “holy cow, man, look at your browser!”) Nonetheless, I have long thought that it would be worth getting my total tab count down. I have tabs open for a bunch of reasons.

Big Tech are supposed to be the plumbers, not patricians of internet discourse
When tech companies take it upon themselves to arbitrate what is or isn't misinformation they think they're the patricians of internet discourse. The reality is they're the plumbing. Meanwhile, most of the mainstream media coverage around the pandemic can be classified into five logical fallacies.

The macOS Sandbox File Limit
There has recently been some renewed discussion on Twitter about the limitation that the macOS sandbox places on the number of open files an app can access at once. Apps are still running into problems because of this limitation, and there is not a lot of technical detail available on it outside of Apple, so I’d like…

; Echo “Shell Injection”
This is an introductory article about shell injection, a security vulnerability allowing an attacker to execute arbitrary code on the user's machine. This is a well-studied problem, and there are simple and efficient solutions to it. It's relatively easy to design library API in such a way as to shield the application…

Increase HTTP performance by fitting in the initial TCP slow start window
Did you know that if your site’s under ~12kb the first page will load significantly faster? Servers only send a few packets (typically 10) in the initial round-trip while TCP is warming up (referred to as TCP slow start). After sending the first set of packets, it needs to wait for the client to acknowledge it…
