SBT is the default build tool for the Scala programming community: you can build Scala using other tools, but the vast majority of the community uses SBT. Despite that, nobody seems to like SBT: people say it's confusing, complicated, and opaque. This post will deeply analyze what exactly it is about SBT that people…
In 1996, Paul Kocher published a novel attack on RSA, specifically on RSA implementations , that extracted information on the private key by simply measuring the time taken by the private key operation on various inputs. It took a few years for people to accept the idea that such attacks were practical and could be…
Project Loom's mission is to make it easier to write, debug, profile and maintain concurrent applications meeting today's requirements. Threads, provided by Java from its first day, are a natural and convenient concurrency construct (putting aside the separate question of communication among threads) which is being…
I normally do not read comp.lang.c, but Jim McKie told me that `` Duff's device '' had come up in comp.lang.c again. I have lost the version that was sent to netnews in May 1984, but I have reproduced below the note in which I originally proposed the device. (If anybody has a copy of the netnews version, I would…
smallpt is a global illumination renderer. It is 99 lines of C++, is open source, and renders the above scene using unbiased Monte Carlo path tracing (click for full size) .
“The Implementation of Functional Languages” is a book about implementing functional programming languages using lazy graph reduction, and it divides into three parts. The first part describes how to translate a high-level functional language into an intermediate language, called the lambda calculus, incuding detailed…
This PEP describes an addition to the standard library called Data Classes. Although they use a very different mechanism, Data Classes can be thought of as “mutable namedtuples with defaults”. Because Data Classes use normal class definition syntax, y...
A look at the Go GC strategy
Update: This post got a sequel, Breaking our latin-1 assumptions. I’ve seen misconceptions about Unicode crop up regularly in posts discussing it. …
Gitea is a community fork of the popular self hosted Git service Gogs. We're a growing group of former Gogs users and contributors who found the single maintainer management model of Gogs frustrating and thus decided to make an effort to build a more open and faster development m

You're not alone, jclancy. In the five years since this question was asked, there have been over a million other developers who got stuck in Vim and couldn't escape without a bit of help. Indeed, the difficulty of quitting the Vim editor is a common joke among developers.
How we will all work together toward Go 2.
Pagination, pervasive as it is in web applications, is easy to implement inefficiently. This post examines different methods of server-side pagination and their tradeoffs in PostgreSQL. Methods explored include limit-offset, cursors, keyset pagination, as well as more exotic techniques.
This time we'll focus on Linux's select(2) successor - the epoll(2) I/O multiplexing syscall.
To type or not to type: quantifying detectable bugs in JavaScript Gao et al., ICSE 2017 This is a terrific piece of work with immediate practical applications for many project teams. Is it worth th…
My twitter feed has recently been filled with discussions about the following program #include <cstdlib> typedef int (*Function)(); s...
There are lots of people and places that create and collect algorithms of all types ( here are a few WWW sites). Unfortunately, in building systems hardware and software, we in The Aggregate often have found it necessary to do relatively obscure low-level things very efficiently. Many of the tricks we've devised or…
Hi everyone. About half a year ago whenever I was sitting deeply in Factorio and when I needed to spend time in my phone, I was reading FFF or Factorio forum. Later when I decided to move - I suddenly realized that Wube is the most logical target to apply my crazy mind. All thanks to those FFF and you guys. Now I am…
Have you heard of the Bitcoin Lightning Network? It is a proposal that claims that:
What is slack doing? The process was in the background when this happened. I wasn't even interacting with it - I was in a meeting. I only noticed because my laptop fans were whurring when I got back. Restarting slack seemed to fix it for now. But that's not abnormal
Welcome to this tutorial series on ARM assembly basics. This is the preparation for the followup tutorial series on ARM exploit development . Before we can dive into creating ARM shellcode and build ROP chains, we need to cover some ARM Assembly basics first.
Building resilient services by identifying foreign state mutations and grouping local changes into restartable atomic phases so that every request can be driven to completion.
We’re going to reproduce some results from papers on filesystem robustness that were written up roughly a decade ago : Prabhakaran et al. SOSP 05 paper , which injected errors below the filesystem and Gunawi et al. FAST 08 , which looked at how often filesystems failed to check return codes of functions that can…
