JDK 16 is out, and as usual, each new release comes with a bunch of new features, enhancements and bug fixes. ZGC received 46 enhancements and 25 bug fixes. Here I’ll cover a few of the more interesting enhancements.
In the previous post, we discovered the potential for data loss in RabbitMQ clusters . In this oft-requested installation of the Jepsen series, we’ll look at etcd : a new contender in the CP coordination service arena. We’ll also discuss Consul ’s findings with Jepsen.
Do you love ("very") high-level languages? Like Lisp, Smalltalk, Python, Ruby? Or maybe Haskell, ML? I love high-level languages.
It’s terribly punny/dorky of me, but reading your post it just occurred to me one could start a blog called “Race Condition” about being a person of color and being a computer scientist.
ABSTRACT In May 2003, the University of Wisconsin - Madison found that it was the recipient of a continuous large scale flood of inbound Internet traffic destined for one of the campus' public Network Time Protocol (NTP) servers. The flood traffic rate was hundreds-of-thousands of packets-per-second, and hundreds of…
In compression theory, the entropy encoding stage is typically the last stage of a compression algorithm, the one where the gains from t...
I like to think of Stack Overflow as running with scale but not at scale. By that I meant we run very efficiently, but I still don’t think of us as “big”, n...
My homepage for projects, jokes and bunnies.
The day before I submitted this column, news hit the net that the other shoe had finally dropped. After months of waiting and wondering what was to become of Be, we learned that Palm, Inc. will be purchasing Be's technology, intellectual property, and assets. While we don't yet know exactly what Palm plans to do with…
A look at the Go GC strategy
Previously in Jepsen , we discussed Redis . In this post, we’ll see MongoDB drop a phenomenal amount of data. See also: followup analyses of 2.6.7 and 3.4.0-rc3 .
One of the key gaps in Rust’s ecosystem has been a strong story for fast and productive asynchronous I/O . We have solid foundations, like the mio library, but they’re very low level: you have to wire up state machines and juggle callbacks directly.
Many programming "best practices" taught today are performance disasters waiting to happen.
Please note: our followup analysis of 3.4.0-rc3 revealed additional faults in MongoDB’s replication algorithms which could lead to the loss of acknowledged documents–even with Majority Write Concern, journaling, and fsynced writes.
Apple’s latest line of Macs includes their in-house “M1” system-on-chip, featuring a custom GPU. This poses a problem for those of us in the Asahi Linux project who wish to run Linux on our devices, as this custom Apple GPU has neither public documentation nor open source drivers. Some speculate it might descend from…
Your browser doesn't seem to support CSS , which this page uses for all styling. Don't be surprised if it looks kinda boring.
There's been some recent discussion about whether the X server is abandonware. As the person arguably most responsible for its care and feed...
In this Jepsen report, we’ll verify RethinkDB’s support for linearizable operations using majority reads and writes, and explore assorted read and write anomalies when consistency levels are relaxed. This work was funded by RethinkDB, and conducted in accordance with the Jepsen ethics policy .
It was a quiet Wednesday afternoon. Wednesday, 1st October, 15:15 BST, to be precise, when Peter, an office-mate of mine, leaned away from his terminal and said to me, " Mario, I'm having a little trouble sending mail. " Knowing that msg was capable of confusing even the most capable of people, I sauntered over to his…
This article explains how to correctly handle filenames in Bourne shells (the primary shell of Unix/Linux/POSIX systems), based on the issues discussed in 'Fixing Unix/Linux/Filenames'. Many programs fail to work properly on filenames that include spaces, begin with dash (-), include newlines, and so on, because…
When you have to build a web application, you are often asked to add search. The magnifying glass is something that we now add to wireframes without even knowing what we are going to search.
The size of binaries in the Nim programming language seems to be a popular topic recently . Nim’s slogan is expressive, efficient, elegant , so let’s examine the efficient part in this post by exploring a few ways to reduce the size of a simple Nim Hello World binary on Linux. Along the way we will:
git , Single page HTML , Kindle .mobi , PDF , .epub , HTML for printing , book cover .
How many problem domains require wrapping signed integers or non-wrapping unsigned integers? Can the current undefined case be replaced with a trap and everything else be left intact?
This post is about uninitialized memory, but also about the semantics of highly optimized “low-level” languages in general. I will try to convince you that reasoning by “what the hardware d...
