The Technology Behind GitHub’s New Code Search
- Timothy Clem tl;dr: "We were motivated to create our own solution by three things: (1) We’ve got a vision for an entirely new user experience that’s about being able to ask questions of code and get answers through iteratively searching, browsing, navigating, and reading code. (2) We understand that code search is uniquely different from general text search. (3) GitHub’s scale is truly a unique challenge... north of 200 million repositories.featured in #388
Why Does 0.1 + 0.2 = 0.30000000000000004?
- Julia Evans tl;dr: "This is roughly how floating point addition works: (1) Add together the numbers with extra precision (2) Round the result to the nearest floating point number... So let’s use these rules to calculate 0.1 + 0.2. I just learned how floating point addition works yesterday so it’s possible I’ve made some mistakes in this post, but I did get the answers I expected at the end."featured in #388

Reversing UK Mobile Rail Tickets
tl;dr: "But what data is inside the barcode of a mobile ticket, and how do they work? Could people who aren’t ticket inspectors get the data out of them? It turns out that the answer is a bit more interesting than I initially expected!" The author shows your ticket barcode, which is often written below the code in plain text, might let someone access a surprising amount of detailed tracking information as to where you are and what trains you’re taking.featured in #387
Asynchronous Computing At Meta: Overview And Learnings
- Sayak Kundu Artem Denisov tl;dr: "We have built a platform for serverless asynchronous computing that is provided as a service for other engineering teams. They register asynchronous functions on the platform and then submit workloads for execution via our SDK. The platform executes these workloads in the background on a large fleet of workers and provides additional capabilities such as load balancing, rate limiting, quota management, downstream protection and many others."featured in #387
How We Improved DNS Record Build Speed By More Than 4,000x
- Alex Fattouche tl;dr: "Our network now spans over 270 cities in over 100 countries, interconnecting with more than 10,000 networks globally. According to w3 stats, “Cloudflare is used as a DNS server provider by 15.3% of all the websites.” This means we have an enormous responsibility to serve DNS in the fastest and most reliable way possible."featured in #383

Hello World Under The Microscope
tl;dr: "We will trace the execution path of the "Hello World" micro-program written in Python and run on Windows, starting from a single call to the high-level print function, through the subsequent levels of abstraction of the interpreter, operating system and graphics drivers, and ending with the display of the corresponding pixels on the screen. As it turns out, this path in itself is neither simple nor short, but definitely fascinating."featured in #359
