If you're doing high performance Java you're definitely looking at the compiler output. At least you should be. It's arguably more important with Java than with the compiler output for something like C++, as C2 is much more

Anyone who is involved in any sort of performance critical work looks at compiler output on a regular, if not daily basis.

A lot of this is due the size of the corpus. Grep falls apart for severely underspecified queries, which is the difficult part of web search. For any given query in web search there can be several millions of candidate results. You can ge

Also hard to overstate the sheer impact of a tool like Excel, which in many ways is an ad-hoc programming tool so intuitive that anyone can learn to use it. Even though it sees more jeer than celebration, and is often something techies s

This was pretty much always wrong. Nobody writing performance critical code in Java trusts the compiler to magically figure things out, and the sort of code you arrive at if you want Java to go fast is generally unidiomatic.

Printing presses are not typewriters. The printing press did displace the manual copying of manuscripts, which had insanely low bandwidth and generally kinda sucked for everyone involved. But for several hundred years after, until the indu

Making a staggering $800/mo off Marginalia Search nowadays, off donos and API deals. Seems to be a pretty decent interest in API access now that everyone and their mother is building a personal AI assistant.

Workflows will randomly break and things will move around and change names even more often than before!

It's also chemistry. As long as we're using natural gas, there be a surplus of cheap ethane and we'll indirectly subsidize plastic, since making plastic out of the ethane puts that waste product to use (by creating plastic wa

Yeah it'll be great when plastic starts to rot like wood. Thank god we haven't spent the last 60 years using plastic as a water proof electrical insulator.

So you're a peasant in England in the 1300s. You caught the end of the medieval warm period, a period of unusually warm climate in Europe. It's been really easy to grow food, and the population of Europe has boomed. That ends in

Eh, this is true prior to an IPO, but listed companies (like every single one doing this shit) are very much beholden to shareholders and quarterly reports.

Thing with investor money is that after a while the investors start asking where their dividends are at. If you put all that money toward building features nobody asked for, you're in for a rough time.

As long as you're scheduled by the kernel and not something like Kubernetes with a CPU limit, you can generally oversubscribe I/O threads without much of a problem. They're mostly parked waiting for syscalls anyway. Heck, e

Even so you could use cgroups to cap the memory for the process (including its caches).

I'm no fan of journald, but I have some methodological issues with this test. The reads from /tmp/all.log are almost certainly cached since you just wrote the file, and will basically boil down to a memcpy call, rather than a

I wonder if this is related to their text watermarking. Given how well defined the terminology is in programming, imposing additional constraints (like SynthID) might be expected to give rise to these types of linguistic artifacts. The te

You get the exact same information in $ man systemd.exec Though reading the question again, I should have probably linked to the equivalent of $ man systemd-system.conf as well, that's where you can set the default behavior across syst

I did, and I still don't get why you would want this monstrosity over a structured append-only log file. If you want to index the data, you can do that when you roll over the file. That way you get the exact same robustness guarantee

What is the real-world use for these features? Who is this built for? Modern drives will read data at 500MB/s, sometimes even more. Your log files are approaching tens if not hundreds of gigabytes before a sequential read stops being

Yeah docker does a ton of network stuff when you start/stop containers, depending on your configuration. It's extra fun because it can drop existing connections when that happens. Had a process quietly in a crash loop for a solid

Parquet is probably an even better option. Columnar, compression, fast, succinct. All good things. You can read them with DuckDB, but you don't end up with O(log n) writes -- which is, to speak plain English, batshit fucking insane

Well there was an ambition, apparently. > Performance: journal operations for appending and browsing should be fast in terms of complexity. O(log n) or better is highly advisable, in order to provide for organization-wide log monitoring

There are mitigations in both software and hardware, but most consumer machines, by default, do almost none of that. No ECC RAM, no error correction in the filesystem.
