First, no, I don't do every thing in assembly. I use other languages too. Assembly language does have its place though. Second, a few of my points may not apply to highly complex processors; for example, self-modifying code may not work on a processor with an instruction cache .
Hardware performance “obviously” affects software performance and affects how software is optimized. For example, the fact that caches are multiple orders of magnitude faster than RAM means that blocked array accesses give better performance than repeatedly striding through an array.
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...
#NodeJS : A quick optimization advice Can you spot the difference between these two files : that can explain a 50% performance gain : If you don’t, it’s normal, you try to read the code …
I was finally tempted into writing this from a Hacker News discussion on “ Debian Dropping the Linux Standard Base ,” where some interest was expressed in reading an architectural critique of systemd.
So, Windows 10 has just been released, and with it Ahead Of Time (AOT) compilation feature .NET native . Google also just recently introduc...
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…
This is a co-production with Veedrac, who wrote most of the awesome technical details.
Cowboy is the most popular Erlang framework for writing web servers. It is really impressive to see what cowboy accomplishes with such…
The Rust programming language has been able to run on bare-metal without the standard library for quite some while now. However, most Rust applications depend on the std crate, and therefore still need a full operating system to run.
The Google transport networking crew (QUIC, TCP, etc..) deserve a shout out for identifying and fixing a nearly decade old Linux kernel TCP ...
Percona’s CTO Vadim Tkachenko wrote a response to my Galera Snapshot Isolation post last week. I think Tkachenko may have misunderstood some of my results, and I’d like to clear those up now. I’ve ported the MariaDB tests to Percona XtraDB Cluster, and would like to confirm that using exclusive write locks on all…
I've been noticing more and more lately that we have a plethora of libraries and programs written for Go, which don't work on one platform o...

Microservices are a thing these days.
Experienced professional software engineer based in York, UK
Back in June, I was doing some analysis on a Windows driver and discovered that the INIT section had the read, write, and executable characteristics flags set. Windows executables (drivers included…
Previously, on Jepsen, we saw Chronos fail to run jobs after a network partition . In this post, we’ll see MariaDB Galera Cluster allow transactions to read partially committed state.
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
