What I think is funny is that circa 2008 I had a manager who used to work at Amazon who told me that "a surprising amount of Amazon artificial intelligence is artificial artificial…

I really think that they bury the lede: > As a setuid program meant for elevating privileges, all code that is compiled into sudo-rs has the potential to accidentally (or intention…

I used it and even took a class taught by salt stack employees. I really was not a fan. I think one of the core problems I ran into was that the tool attempted to layer on rpc beha…

I'm not sure if I follow but it does occur to me that being thrifty and changing from a aerospace engineering company to a financial engineering company can be two different things…

This is a very sharp tool and I find it's really rare to need it. I do alot of profiling and performance optimization. Especially with go. Allocation and gc is often a bottleneck. …

Going on 5+ years using a single giant org file. It's the only system I've ever been able to stick with for more than a couple days. I think of it as my labbook.

I love and hate this. On a visceral level I don't like dealing with issues via malicious compliance. OTOH I absolutely agree this is a good call if your goal is for more users to b…

> DNS without CGO works perfectly It does not. I know this because it impacts my daily work and the work of others. Honestly if you could make my day and go figure out exactly what…

I do like this about go. And on Linux it arguably makes sense (I say arguable because DNS without CGO is still a common cause of issues and incompatibility). But Linux has, to the …

There's a lot of subtleties. It's really easy to accidentally load test the wrong part of your web application due to differences in compression, cache hit ratios, http settings, e…

> My initial requirement was to send requests with unique parameters. To the best of my knowledge, no tool could do this. wrk does this with lua. https://github.com/wg/wrk/blob/mas…

Android has a BLE scanner app that can passively read info. I don't know enough about the protocol to know if that is the same thing you are referring to.

No memory leaks (unless you use shared memory). No weird connection pooling and caching issues or delays in picking up a config change. Every request is a fresh start, enforced by …

The actual damage is that it's pretty common (my last team has this happen) for a team to setup a cert, verify it works, and then when they deploy the cert it works some of the tim…

cryptography. Things that really need to be constant time and not be "optimized" by the compiler. See the .s files in: https://cs.opensource.google/go/go/+/refs/tags/go1.21.5:src/.…

text/template is probably ok... For some version of text. ditto with jinja and most templating languages. The cardinal sin of DevOps is using text macros to produce structured data…

I also ran into spooky negative dentry issues. On a fleet of seemingly identical physical machines one machine would constantly check for files that didn't exist (iirc it was someh…

It's the old "you are not the customer" but applied to management. I really really want to be told what the high level goals are and come up with a solution. So of course when I st…

This is an underrated capability (patching up requests) that many devops folks often take advantage of in platforms like haproxy, nginx, etc. I once worked at a company where someo…

Like laws? Or rules? Sure. They are methods of control.

Sorry, but that's not true. I wish it was. But running anything that bridges google3 and GCP is a nightmare. Outside of acquisitions and OSSish stuff like chrome, it's really rare …

I think this is a great idea. In the old days before fuse was so widely used I saw this same idea used in the jvm since it supports custom protocol handlers that you can use for vf…

It's basically still the only game in town for a high performance shared posix filesystem with multiple writers and builtin support in basically all operating systems. As an applic…

I have a simple guess. We are in a post zirp (zero interest rate policy) world. I've seen very large companies embracing degrowth. Quite possibly Microsoft told it's subsidiary Git…

I've noticed that this week. After spending a little time just reading on how to correctly write posix compliant code that was also guaranteed to do what I want, it's hard to come …
