In the ELF format there are two ways of providing a hash table of symbols. DT_HASH and DT_GNU_HASH . The first one is part of SYSV generic ABI and is well documented and marked as mandatory. DT_GNU_HASH is a newer, smaller, and faster replacement that is not documented , implemented in a few places (Glibc, GNU ld…
If someone knows even a little about Spanner, the first question they have is: "How does CockroachDB provide external consistency without atomic clocks?"

WSL 2 is a new architecture that allows for dramatic file system performance and full system call compatibility in WSL using a Linux kernel.
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.
One of our large scale data infrastructure challenges here at Cloudflare is around providing HTTP traffic analytics to our customers. HTTP Analytics is available to all our customers via two options:
Last November I went to an IETF meeting for the first time. The IETF is an interesting place; it seems to be about 1/3 maintenance grunt wo...
While I was writing the post comparing the new Qualcomm server chip, Centriq, to our current stock of Intel Skylake-based Xeons, I noticed a disturbing phenomena.
This comes up far too often, so rather than continuing to explain it over and over again, I’m going to try to do a really good job of it once and link to it here.
200 SQL statements per webpage is excessive for client/server database engines like MySQL, PostgreSQL, or SQL Server.
Memory Integrity Enforcement (MIE) is the culmination of an unprecedented design and engineering effort spanning half a decade that combines the unique strengths of Apple silicon hardware with our advanced operating system security to provide industry-first, always-on memory safety protection across our devices …
One of my favorite Amazon Leadership Principles is Customer Obsession. When we launched AWS Lambda, we focused on giving developers a secure serverless experience so that they could avoid managing infrastructure. In order to attain the desired level of isolation we used dedicated EC2 instances for each customer. This…
This page is about a technique for reducing the memory footprint of programs in compiled languages with C-like structures - manually repacking these declarations for reduced size. To read it, you will require basic knowledge of the C programming language.
A catalogue of software constructs, languages, or APIs which are unexpectedly Turing-complete; implications for security and reliability.

tl;dr: Having swap is a reasonably important part of a well functioning system. Without it, sane memory management becomes harder to achieve.
Insights from Googlers into our products, technology, and the Google culture
A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room…
An introduction to the idea that code should be approached with a mindset towards compressing it semantically, rather than orienting it around objects.

How to use Go's built-in profiler to understand and optimize your programs.
A couple years ago, I took a road trip from Wisconsin to Washington and mostly stayed in rural hotels on the way. I expected the internet in rural areas too sparse to have cable internet to be slow, but I was still surprised that a large fraction of the web was inaccessible. Some blogs with lightweight styling were…
