The latest blog posts to take off on Hacker News. 190 posts.
We started listing xz-compressed versions of kernel archives in all our announcements back in March 2013, and the time has come to complete the switch. Effective immediately, we will no longer be providing bzip2-compressed versions for new releases of the Linux kernel and other software. Any previously released…
A few minutes ago I came across a Hacker News post that detailed a method of adding search to your static site. As you probably know, adding search to a static site is a bit tricky, because you can’t just send the query to a server and have the server process it and return the results. If you want full-text search…
A few weeks ago I criticized a proposal by Antirez for a hypothetical linearizable system built on top of Redis WAIT and a strong coordinator. I showed that the coordinator he suggested was physically impossible to build, and that anybody who tried to actually implement that design would run into serious problems. I…
asm.js is a simple subset of JavaScript that is very easy to optimize, suitable for use as a compiler target from languages like C and C++. Earlier this year Firefox ...
Day 45: I now have Rust code for executing executables!
The AppNeta award-winning suite of network monitoring tools allow unparalleled SaaS-based application end-user performance monitoring for 100% delivery confidence.
There’s a key piece of magic in the engineering of the Internet which you rely on every single day. It happens in the TCP protocol, one of the fundamental building blocks of the Internet. TCP…
TLS is not slow, it's unoptimized. A hands-on tour of optimizing nginx to deliver one-RTT Time To First Byte (TTFB) with TLS.
Today's announced collaboration between Red Hat and dotCloud , the company behind Docker, is exciting for a lot of reasons. As the release n...
In a recent blog post , antirez detailed a new operation in Redis: WAIT . WAIT is proposed as an enhancement to Redis’ replication protocol to reduce the window of data loss in replicated Redis systems; clients can block awaiting acknowledgement of a write to a given number of nodes (or time out if the given threshold…
C is, today, a unique programming language. Surprisingly few people can really program in C and yet many of us have quite strong opinions about it. Buffer overflows, stack smashing, integer overflows — C has many well publicised flaws, and these terms are often bandied about confidently, even by those unfamiliar with…
A couple of years ago I wrote an article about the Curiously Recurring Template Pattern in C++ , focusing on the motivation behind it and how to implement it.
Since this January, David Anderson and I have been working on making Firefox use multiple processes. Tom Schuster (evilpie on IRC) joined us as an intern this summer, and Felipe Gomes, Mark Hammond…
Day 37: After 5 days, my OS doesn't crash when I press a key
I recently scored a Hewlett Packard 1670A Deep Memory Logic Analyzer and I finally had a chance to fire it up. This unit dates back to 1992 ...
Day 36: On programming without malloc
Recently I've been doing some benchmarking and came upon a very surprising behavior from a number of different Intel i7 CPUs (it manifests on Sandy Bridge and Haswell desktop-class CPUs as well as Sandy Bridge-EP Xeon CPUs).
Citus gives you all the greatness of Postgres plus the superpowers of distributed tables. By distributing your data and queries, your application gets high performance—at any scale. The Citus database is available as open source and as a managed service on Azure.
This talk is about using simple values (as opposed to complex objects) not just for holding data, but also as the boundaries between components and subsystems. It moves through many topics: functional programming; mutability's relationship to OO; isolated unit testing with and without test doubles; and concurrency, to…
Last week, during Tomas ' keynote at MySQL Percona Live Conference in London we announced as one of "previews" of the following MySQL 5.7 release(s) -- an over 1,000,000 Query/sec result obtained with InnoDB Memcached plugin on a Read-Only workload. This article here is just to confirm the announced results without…
A couple nights ago I was looking over the UEFI spec, and I realized it shouldn't be too hard to write UEFI applications in Rust. It turns out, you can, and her…
In this article I want to explore what happens when a statically linked program gets executed on Linux. By statically linked I mean a program that does not require any shared objects to run, even the ubiquitous libc . In reality, most programs one encounters on Linux aren't statically linked, and do require one or…
As I was exiting Oxford Railway Station, I glanced at this screen showing the bus departure times. Notice anything odd about it? sigh Yet again someone has shoehorned Microsoft Windows into a product it is completely unsuitable for. Why does a screen which displays a fairly basic set of information need to be running…
Kim: Yeah, right. It's just sockets . Course, it's totally portable so you don't have to handle all the weird stuff different operating systems ask you to do.
