Files Are Hard
I haven't used a desktop email client in years. None of them could handle the volume of email I get without at least occasionally corrupting my mailbox. Pine, Eudora, and outlook have all corrupted my inbox, forcing me to restore from backup. How is it that desktop mail clients are less reliable than gmail, even…

A Constructive Look at TempleOS
TempleOS is somewhat of a legend in the operating system community. Its sole author, Terry A. Davis , has spent the past 12 years attempting to create a new operating from scratch. Terry explains that God has instructed him to construct a temple , a 640x480 covenant of perfection. Unfortunately Terry also suffers from…

Will ZFS and non-ECC RAM kill your data?
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.

To ECC or Not to ECC
On one of my visits to the Computer History Museum – and by the way this is an absolute must-visit place if you are ever in the San Francisco bay area – I saw an early Google server rack circa 1999 in the exhibits. Not too fancy, right? Maybe even… a

Call Me Maybe: MongoDB Stale Reads
Please note: our followup analysis of 3.4.0-rc3 revealed additional faults in MongoDB’s replication algorithms which could lead to the loss of acknowledged documents–even with Majority Write Concern, journaling, and fsynced writes.

Nim binary size from 160 KB to 150 Bytes
The size of binaries in the Nim programming language seems to be a popular topic recently . Nim’s slogan is expressive, efficient, elegant , so let’s examine the efficient part in this post by exploring a few ways to reduce the size of a simple Nim Hello World binary on Linux. Along the way we will:

There Is No Thread
This is an essential truth of async in its purest form: There is no thread.

Lock freedom without garbage collection in Rust
It’s widespread folklore that one advantage of garbage collection is the ease of building high-performance lock-free data structures. Manual memory management for these data structures is not easy, and a GC makes it trivial.

Structural and semantic deficiencies in the systemd architecture
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.

Call me maybe: Elasticsearch 1.5.0
Previously, on Jepsen , we demonstrated stale and dirty reads in MongoDB . In this post, we return to Elasticsearch, which loses data when the network fails, nodes pause, or processes crash.

151-byte static Linux binary in Rust
Part of the sales pitch for Rust is that it's "as bare metal as C". 1 Rust can do anything C can do, run anywhere C can run, 2 with code...

Redundancy vs. dependencies: which is worse? (2008)
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…

Why Intel Added Cache Partitioning
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…

What's New in CPUs Since the 80s and How Does It Affect Programmers?
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…
