How much overhead should we expect from enabling integer overflow checks? Using a compiler flag or built-in intrinsics, we should be able to do the check with a conditional branch that branches based on the overflow flag that add and sub set. Code that looks like
This time we'll focus on Linux's select(2) successor - the epoll(2) I/O multiplexing syscall.
Concurrent operations can be grouped relatively neatly into categories based on their cost
The urge to replace the mainframe has reinvented the mainframe and its problems.
Investigating some details of SIMD related frequency transitions on Intel CPUs.
I usually write about security features or techniques on Windows. But today’s blog is not directly related to any security topics, other than the usual added risk that any new system call introduces. However, it’s an interesting addition to the I/O world in Windows that could be useful for developers and I thought it…
This post explains the project's motivation from several perspectives. Unix shell is an old and successful technology, so there are many ways of looking at it.
Dash knows your context, your team, and your work, so your team can stay organized, easily find and share knowledge, and keep projects secure, all from one place.
In this blogpost I argue why it's strongly recommended to use ZFS with ECC memory when building a NAS. I would argue that if you do not use ECC memory, it's reasonable to also forgo on ZFS altogether and use any (legacy) file system that suits your needs.
In Prague, the C++ committee took a series of polls on whether to break ABI, and decided not to. There was no applause. But I’m not sure we fully understood what we did and the consequences it could have.
Introduction: Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32
Update: Here's how to get started using Ubuntu on Windows See also Scott Hanselman's blog here I'm in San Francisco this week, attendin...
Listen in on Jane Street’s Ron Minsky as he has conversations with engineers working on everything from clock synchronization to reliable multicast, build systems to reconfigurable hardware. Get a peek at how Jane Street approaches problems, and how those ideas relate to tech more broadly.
I couldn't remember every UUID so I wrote them all down
What goes on behind the magical macros in the C protothreads library? Why are they macros? How do the macros work? Read on for the explanation.
Numerous claims about Judy's performance are made in the Judy whitepaper . I don't think any of those claims are wrong. However, it does not appear that sufficient effort was put in benchmarking Judy against other data structures. Now, it is unlikely there is another data structure that is both as fast and as small as…
This article is part of Jepsen , a series on network partitions. We’re going to learn about distributed consensus, discuss the CAP theorem’s implications, and demonstrate how different databases behave under partition.
Cloudflare is a security company, and the heart of Workers is, in my view, a security project. Running code written by third parties is always a scary proposition, and the primary concern of the Workers team is to make that safe.
The Backend Infrastructure team at Discord was hard at work improving the scalability and performance of our core real-time communications infrastructure.
We’ve always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we’re performance wonks (guilty!), but because we think speed is a competitive advantage. There’s plenty of experimental data proving that the slower your website loads and displays, the less people
Discover how Expensify achieved remarkable scaling: 4M QPS on one server! Dive into optimizing SQLite for impressive performance gains.
For lists of FreeBSD AMI IDs, please consult the appropriate FreeBSD release announcement; you can also launch FreeBSD through the AWS Marketplace .
Cloudflare’s mission is to help build a faster and more secure Internet. Over the last several years, the Internet Engineering Task Force (IETF) has been working on a new version of TLS, the protocol that powers the secure web.
For the first time, a large high-temperature superconducting electromagnet was ramped to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created. The demonstration helps resolve the greatest uncertainty in the quest to build the first fusion power plant that can produce more energy than…
Last week during a casual conversation I overheard a colleague saying: "The Linux network stack is slow! You can't expect it to do more than 50 thousand packets per second per core!"
