Homomorphic encryption allows a computer to run programs on encrypted data. Learn how homomorphic encryption works through interactive examples, build a homomorphically encrypted CRDT and see whether it has promise for local-first software.
In late 2016 I began helping Forgotten Empires on Age 1 DE , a UWP app shipping in the Windows Store on Feb 20th. I only helped occasionall...
Today, I’m releasing deflect , an implementation of reflection for Rust. Deflect can be used to recover the concrete types of trait objects, inspect the internal state of async generators, pretty-print arbitrary data, and much more.
Forgotten TODOs: ideas for contributing to open-source projects
Several years ago, I spent a serious chunk of time figuring out how to make really teensy ELF executable files. I started down this path because I was annoyed that all of my programs, no matter how short they were, never got smaller than 4k or so. I felt that was excessive, for C, and so I started looking at what ELF…
At Browserling we are huge open-source fans and we have open-sourced 90 node.js modules! That's right! 90 node.js modules. All written from scratch. We're crazy! Edit: Now we've open-sourced several hundred! Here is the complete list of all the modules together with their brief descriptions. We have published all…
Yet another big problem of the Internet era tackled by Mathematics. Looping GIFs are a very popular form of art on the Web, with two dedicated forums …
Using Java or Python in a professional IDE like IntelliJ IDEA, NetBeans, PyCharm, or Eclipse is not a good first introduction to programming for computer science students, whether they’re in the field to become web developers, systems software engineers, or academic computer science researchers.
In the fall of 2000, I took my first engineering class: ECE 352 , an entry-level digital design class for first-year computer engineers. It was standing room only, filled with waitlisted students who would find seats later in the semester as people dropped out. We had been warned in orientation that half of us…
Lessons about XML from the open source IRS Tax Withholding Estimator.
How X Window Managers Work, And How To Write One (Part I)
Intro The goal of this tutorial is to describe Python development ecosystem. It can be helpful for someone coming to Python from another programming language. They say that you should stick to algorithms and data structures, that you can learn a new language in just a couple of weeks, that it’s just a new syntax. I…
Elm 0.19 was released yesterday. There were a significant number of breaking changes at every level:...
This a rant, written at midnight, after battling software errors. Set your profanity filters accordingly. I despair over the state of software engineering - specifically, stability. We seem to have lost the understanding that computers are there to do the hard work for us. And I don't think we ever believed in a…
Explaining the different mental model Deno has about managing dependant code.
Systemd has a remotely exploitable bug in its DHCPv6 client . That means anybody on the local network can send you a packet and take control...
Why should anyone care about low-level programming?
There are three questions you have when you’re hiring a programmer (or anyone, for that matter): Are they smart? Can they get stuff done? Can you work with them? Someone who’s smart but doesn’t get stuff done should be your friend, not your employee. You can talk your problems over with them while they procrastinate…
Antonio Cuni's blog
It all started with Instagram Reels showing me too many yummy cooking videos. I wanted to try some recipes out myself. But I didn’t want to have to keep my phone in the kitchen, and I didn’t want to have to keep unlocking it to see the next step. I wanted to print the recipe out, and have it on the counter while I was…
Tiark Rompf is an Associate Professor at Purdue University. Notes and blog posts on programming, research, CS, software systems.
Programmers often need to 'filter out' data. Suppose that you are given a database of users where only a small percentage are 'paying customers' (say 5% or less). You can write an SQL query to check whether a given user is indeed a paying customer, but it might require a round trip to your database … Continue reading…
Some hidden features of the Python re module and the support machinery that drives it.
Some notes on the different patterns that may be present when people talk about event-driven architectures.
