In part one of this series we introduced the idea of a message log, touched on why it’s useful, and discussed the storage mechanics behind it. In part two, we discuss data replication. We have our log. We know how to write data to it and read it back as well as how data is persisted. The caveat to this is, although we…
Welcome to LTT Labs - your go-to destination for all things tech. Explore comprehensive test results, insightful commentary, and the latest analysis in hardware.
One large difference between C and most other programming languages is that in C, you have to handle memory yourself rather than having a garbage collector do it for you. Ensuring that memory is allocated at the correct moment is not very difficult (and something that needs to be done manually in pretty much every…
A tale how running your own x509 root CA – for internal services – changed in the last 20 years.
I’ve got this rock64, which is an aarch64 board comparable to a Raspberry Pi 3 B+ with 4 gigs of ram. For years I’ve wanted to put a distribution on here that doesn’t have a premade image available, mainly because out of all the options on that page I don’t actually like any of them. Well, except NetBSD, but NetBSD…
A problem I experienced when pursuing my PhD and submitting academic articles was that I had built solutions to problems that required dramatic scale to be effective and worthwhile. Responses to my publication submissions often claimed such problems did not exist; however, I had observed them during my time within…
Parallel evolution.
I have developed some interest in the Rust programming language. Rust is a systems programming language which means it gets out of the way of developers interested in reaching low-level internals of a system. What sets it aside from other systems languages though is: Borrow checking to guarantee memory safety…
The Corner is Square's technical blog covering software engineering, APIs, data, open source and more.
See how ClickHouse delivers faster query performance on 500 billion rows of data compared to ScyllaDB, leveraging an Intel NUC mini PC, advanced compression, and materialized views.
Performance results naturally depend on the underlying hardware. The following benchmarks show the execution times for sorting 50 million doubles using different sorting implementations. The measurements were taken on an Apple M1 system using Clang and on an AMD Ryzen 3 Linux system using GCC , both compiled with the…
What connections are, how they affect our systems, and how and why pooling works.
Benchmarking throughput and latency of Amazon AWS Simple Storage Service (S3), Google Cloud Storage (GCS) and Microsoft Azure Storage object storage services
This blog series will examine Git’s internals to help make your engineering system more efficient. Part I discusses how Git stores its data in packfiles using custom compression techniques.
If you had asked me whether or not it was possible to get a 2x speedup for my LazySorted project by adding a single line of code, I would have told you "No way, substantial speedups can really only come from algorithm changes." But surprisingly, I was able to do so by adding a single line using the __builtin_prefetch…
Notes on BPF & eBPF
The new Riptide garbage collector in WebKit leads to a five-fold improvement in latency in the JetStream/splay-latency test.
8 April 2019 by Phillip Johnston • Last updated 22 August 2022For most programmers, a C or C++ program’s life begins at the main function. They are blissfully unaware of the hidden steps that happen between invoking a program and executing main. Depending on the program and the compiler, there are all kinds of…
[Updated on 2022-03-13: add expert choice routing.] [Updated on 2022-06-10]: Greg and I wrote a shorted and upgraded version of this post, published on OpenAI Blog: “Techniques for Training Large Neural Networks”
I play World of Warcraft . Being a Linux user requires me to run this in Wine , a Windows API translation layer. While Wine is continuously improving, its performance in Direct3D games still leaves much to be desired.
StringZilla v4 brings CUDA acceleration for string processing: 109x faster than Nvidia's CuDF on edit distances, plus 52-bit MinHash fingerprinting and AES-based hashing.
Personal experience with moving away from Apple's world.
Machine code isn't scary. If you can make sure your JSON conforms to a JSON schema, you can write machine code.
In order to get the most performant site possible when building the codebase for our public Stack Overflow site, we didn’t always follow best practices.
Microsoft’s in-house Linux, the distribution that grew out of CBL-Mariner, just hit public preview as a general-purpose cloud OS you can run on any Azure VM and coming soon to WSL.
