中文版 In 2015, AWS introduced s2n, a new open source implementation of the TLS/SSL protocols that protect the privacy and integrity of data moving over a network. s2n was designed to be secure, simple, small, and fast. The project is thriving, and we use it extensively. In February, our CISO Stephen Schmidt shared that…
Update: Note that the capture method I use needs to read pixels back from the GPU which can be slow. This means the Windows 10 results are probably worse than they should be. However, without external hardware this seems to be the only way to measure keyboard to screen latency.
The 1973 Fourth Edition of the Unix Programmer’s Manual doesn’t seem to be available online in typeset form. This is how I managed to recreate it from its source code.
As the purpose of a database system is to store data, there is close relationship with the filesystem. Yves Trudeau reconsiders the use of ZFS with MySQL.
Ever since the first EC2 instances launched — the ones which were retrospectively named "m1.small" — Amazon has relied on the Xen hypervisor. No longer: C5 instances use KVM. This sounds like it would be a problem, but in fact that change didn't bother FreeBSD at all: Now that everything uses hardware-based paging…
At Kolide, part of what we do is build a client-server system that facilitates the management of large, isolated installations of an open-source tool called osquery. While I’ve written and spoken about osquery in the past, in this post I want to focus on how we use Go to solve many of the challenges we face building…

I doubt there has ever been a time when software architecture was seen as a raging success. The “three-tier architecture” of the web has held up extremely well and is an excellent place for many people to start. The “12 Factor App” approach has encouraged developers to adopt practices that make deployment and scaling…
Though most relational databases (like MySQL) are "row oriented", in that they keep rows stored together... experience has taught us that pivoting the data arrow so that columns, and not rows, are stored together can be beneficial. This is an old observation that most experienced programmers know about as the…
As some of you may know, there's a wall of lava lamps in the lobby of our San Francisco office that we use for cryptography. In this post, we’re going to explore how that works in technical detail.
Techniques and tools for profiling Go applications including pprof, benchmarks, and memory management analysis.
My VM is lighter (and safer) than your container Manco et al., SOSP’17 Can we have the improved isolation of VMs, with the efficiency of containers? In today’s paper choice the authors investigate …
I've used Linux containers directly and indirectly for years, but I wanted to become more familiar with them. So I wrote some code. This used to be 500 lines of code, I swear, but I've revised it some since publishing; I've ended up with about 70 lines more.
Emerging cryptocurrencies, such as Bitcoin and Ethereum have reached market capitalizations in the billions of U.S. dollars and transactions volumes in the hundreds of millions of U.S. dollars per …
An in-depth look at the challenges faced when scaling the GitLab database and the solutions we applied to help solve the problems with our database setup.
Performance budgets are an essential but under-appreciated part of product success and team health. Most partners we work with are not aware of the real-world operating environment and make inappropriate technology choices as a result. We set a time budget of less than 5 seconds first-load Time-to-Interactive and less…
You know how sometimes if you mistype a filename in Bash, it corrects your spelling and runs the command anyway?* Such as when changing directory, or opening a file. I have an idea: Suicide Linux. Any time - any time - you type any remotely incorrect command, the interpreter cr...

Scaling up TCP servers is usually straightforward. Most deployments start by using a single process setup. When the need arises more worker processes are added.
