HA is an absurdly heavyweight pile of Python and Docker. Get it a real computer — a used “thin client” with 8 GB of RAM is probably less expensive than an RPi4 plus case and power supply.

Sigh. They should never have diluted the “Optane” trademark by sticking it on this trash. The actual Optane branded enterprise SSDs were quite nice, although they were not easy to shop for.

Things go down and need to come back up. Take a look at almost any major cloud incident in the last 15 years — some combination of goofs results in a bunch of services going down. Then it takes many minutes or hours to come back up. Sure, o

Why on Earth did Intel implement this as a 2x2 device? They could have implemented multiple functions or they could have used a PCIe switch or they could have exposed their device as an NVMe device with multiple namespaces, etc. (I won’t

A ways back, I wrote a sort of database that was memory-mapped-file backed (a mistake, but I didn’t know that at the time), and I would have paid top dollar for even a few GB of NVDIMMs that could be put in an ordinary server and could be s

I feel like this is proving my point. You can’t read “Optane” and have any real idea of what you’re buying. Also… were those weird hybrid SSDs even implemented by actual hardware, or were they part of the giant series of massive kludges in

Intel did a spectacularly poor job with the ecosystem around the memory cells. They made two plays, and both were flops. 1. “Optane” in DIMM form factor. This targeted (I think) two markets. First, use as slower but cheaper and higher den

Is there some reasonable way to check whether the Fusion drive is failing? Some quick searches suggest that Apple’s built in tooling doesn’t actually help much.

I’ve helped someone with a rather clean iMac, circa 2019, still supported by Apple. Forget 6 minutes — you can spend a full hour from boot to giving up trying to get anything done. I think that Apple has gotten so used to having fast storag

I’ve seen quite a few pathetic failures of the cool modern ultrasonic-welded seams and also pathetic failures of high end well known athletic brands. But a competently sewn seam really ought to last at least as long as the fabric.

It would be nice if the other end of this could be addressed: a configurable policy to limit resolution of bucket names within an account namespace. Ideally, if someone doesn’t have permission to resolve a bucket name, they shouldn’t even b

Yes. They promise to wipe your data. That SLA has all the nines you can ask for as long as you measure it in the right direction :)

On a MacBook, one can download a data set, reboot, install updates, etc and still have the dataset. Those nice-ish AWS instances will wipe their local storage if they are stopped. Sure, one needs backups, but this is still annoying. Also,

Another stupid part of this: used cooking grease has positive market value! Quite a few companies, even in expensive places like Palo Alto, will happily supply you, for free, with barrels and such to hold your grease, and they'll come

There is a genuinely interesting complexity class called BQP/poly, which is pronounced something like “bounded-error quantum polynomial time with classical advice” (add some more syllables for a complete pronunciation). The JVG algorit

I have a project that has ordinary internal links, but they’re all relative because the entire project can be based at a variable path. If I were to adopt µJS, though, I would probably want to opt in on a per-link basis.

I’m curious: why does the default behavior do the magic replacement for absolute paths links but not for relative paths? Also, perhaps the CDN script snippets in the getting started page should include the integrity attribute.

On the flip side, it’s easy to get a bit stuck down the road by the mere fact that you have a singleton. Maybe you have amazing performance and very carefully managed safety, but you still have a single object that is inherently shared by

This is an unhelpful interpretation. With a decent memory-safe parser, it’s perfectly safe [1] to deserialize JSON or (most of) XML [0] protobuf or Cap’n Proto or HTTP requests, etc. Or to query a database containing untrusted data. You ne

Maybe a little bit. But serde works with JSON (among other formats), and you can use it to read and write JSON that interoperates with other libraries and languages just fine. Kind of like how SQLAlchemy looks kind of like you’re writing n

The whole “zero overhead” thing is IMO a red herring. I care about a few things: stability across versions and languages, space efficiency (sometimes) and performance. I do not care about “overhead” — performance trumps overhead every time.

There are many systems that take a native data structure in your favorite language and, using some sort of reflection, makes an on-disk structure that resembles it. Python pickles and Java’s serialization system are infamous examples, and
