From a 2020's perspective, X11 is deeply weird. It was written back when huge enormous servers were the only systems with enough oomph to do anything useful, and those servers had 128mb of ram (think of something like a sun 3/480

Well, I certainly track capacity by power used by servers under management, but a system that's pinned on one thread is at 100% utilization, for very real definitions of "capacity" but the power consumed will also be some s

Isn't this just a subset of the existing capacity monitoring problem where I want to know how loaded a multi-core system is under the following scenario: Some critical path, single-threaded task is at 100% of capacity of a core; the sy

I'm not sure I'd want to switch to a pure UDP world just because there's lots of bandwidth in the data center. Any situation where Moore's Law works against you will run into problems unless there's back-pressure b

I suspect he's referring to the "D Language Foundation[1]" Mr. Bright, thank you for Empire. Some of my earliest tinkering memories are of upgrading my 5150 to have a V20 CPU and being somewhat pleased that map generation to

I've had the pleasure of dealing with devs who read this and decide it says "emit json formatted text to stdout and let someone else figure it out, just like it says in some web page." The guidance is explicitly "send i

It certainly doesn't say "use a logging library" it says: A twelve-factor app never concerns itself with routing or storage of its output stream. It should not attempt to write to or manage logfiles. Instead, each running pro

I'm saying that, the one thing I know about looks like obvious nonsense -- "write your logs to stdout and let someone else sort it out" -- so I assume the rest of it is equally facile and silly. So now, when I see a reference

It says "send it to stdout and let someone else figure it out." As that someone else, who often has bug reports like "why aren't my log events all in one record in my thing? Because you filled your stdout with newlines!

So -- there's a file, that's created by some something in a container emitting a string of bytes. A file must go through a parsing and serialization phase to be useful to a logging infrastructure. Just because you decorate the c

The twelve factor app says: A twelve-factor app never concerns itself with routing or storage of its output stream. It should not attempt to write to or manage logfiles. Instead, each running process writes its event stream, unbuffered, to

by cduzz 3y ago
No, writing files is nearly as bad as writing to stdout -- both imply someone else has to parse the output. If the logs matter -- write them to an API that retains log structure by serializing it. If the logs don't matter, then they do

There's the "Plumber Problem[1]" by John Siracusa where you watch a story and see a problem in your specific domain that leads you to mistrust the whole story. With the 12 factor nonsense, I see the guidance of "Dump unf

IMO the "3 rules" ought to be: 1. don't give your robot a gun. 2. don't teach it how to put more bullets into the gun you just gave it. 3. don't teach it how to make bullets after teaching it how to reload the gun.

I'm not sure if the version in use at $workplace is out of date or incorrectly configured, but it is a dreadful prometheus client in that it doesn't use labels, it just shovels all the metadata into the metric name like a 1935 sty

If by "gearbox" you mean "Pulley" -- a setup such as this is probably most efficiently done by just putting a big (wide) pulley on the front crankshaft accessory belt and correct diameter pulley on the alternator, to get

Yeah, they didn't mention many specifics; I also imagine that they're just pulling the power off the engine using the accessory belt connected to their existing alternator -> inverter setup. Similarly -- the concerns about how

The thing that will totally replace splunk (and elastic and snowflake and likely several other whole ecosystems) is some random thing pouring data into clickhouse. I am nervous about how clickhouse is going to monetize, whenever they decide

That's certainly true, and also the case in many modern file formats. For example there's the story of the academic studies with falsified data [1] where forensics on the included excel documents showed they'd gone through an

Well, copying is simply not atomic in linux; directory entry operations (rename, link, unlink) are atomic. There is a definition somewhere that says how many bytes may be written atomically; that's it -- past that writes are not atomi

I recently switched from android to the iphone ecosystem; I had a 3a and then a 4a, and recently updated to a 7a, but it never really clicked with me -- just too big. Got a 13 mini; I kinda don't like a bunch of aspects of the iphone e

Oh, I don't dispute that maybe very modern cars have addressed this. I don't swap cars too often and have been pretty happy with my "one transmission, a planetary reduction gearbox" car (maybe there are 2 transmissions,
