I think that all other considerations are of the extrinsic real-world kind – domain modeling, usability, schedules, platforms, etc. I also think that I can show how any "good" programming practice is mainly aimed at minimizing redundancy, dependencies, or both. I even think that you can tell a "good" programmer from a…
Back in summer I have read a new bookpublished by one of the core Intel architects about the Management Engine (ME).I didn’t quite like what I read there. In...
Hamidreza Soleimani's Blog - Just about what I know
Typical server utilization is between 10% and 50%. Google has demonstrated 90% utilization without impacting latency SLAs . Xkcd estimated that Google owns 2 million machines . If you estimate an amortized total cost of $4k per machine per year , that's $8 billion per year. With numbers like that, even small…
My colleague Mingxue Zhao sent me a guest post designed to make sure that you are aware of an important time / clock issue. Note: This post was first published on May 18, 2015. We made some important additions and corrections on May 25, 2015. — Jeff; The International Earth Rotation and Reference Systems (IERS) […]
David Baron put this up in Mozilla’s San Francisco office a while back:
Here at Malwarebytes we are experiencing phenomenal growth, and since I have joined the company over 1 year ago in the Silicon Valley, one my main responsibilities has been to architect and develop several systems to power a fast-growing security company and all the needed infrastructure to support a product that is…
When I joined CloudFlare about 18 months ago, we had just started to build out our new Data Platform. At that point, the log processing and analytics pipeline built in the early days of the company had reached its limits.

An overview of my work on improving SIMD in Rust.
A while ago, I posted about ffvp9, FFmpeg's native decoder for the VP9 video codec, which significantly outperforms Google's decoder (part of libvpx). We also talked about encoding performance (quality, mainly), and showed VP9 significantly outperformed H.264, although it was much slower. The elephant-in-the-room…
Deliver modern applications with NGINX. Explore high-performance load balancing, API gateways, and web server solutions trusted by top global enterprises.
Its not a secret that I've been working on sandboxed desktop applications recently. In fact, I recently gave a talk at devconf.cz about it. However, up until now I've mainly been focusing on the bundling and deployment aspects of the problem. I've been running applications in their own environment, but having pretty…
The microservices architecture can be useful, but to know if it's suitable in your context you need to understand its costs and benefits.
In a recent blog post we explained how to tweak a simple UDP application to maximize throughput. This time we are going to optimize our UDP application for latency. Fighting with latency is a great excuse to discuss modern features of multiqueue NICs.
asm.js is an easy-to-optimize subset of JavaScript. It runs in all browsers without plugins, and is a good target for porting C/C++ codebases such as game engines - which have ...
Microservices are a thing these days.
My mental model of CPUs is stuck in the 1980s: basically boxes that do arithmetic, logic, bit twiddling and shifting, and loading and storing things in memory. I'm vaguely aware of various newer developments like vector instructions (SIMD) and the idea that newer CPUs have support for virtualization (though I have no…
Why you should understand (a little) about TCP
I previously suggested that we might be able to get parallel sequential scan committed to PostgreSQL 9.5. That did not happen. However, I...
