I've no experience with Synology and have no opinion regarding their motivations, execution, or handling of customers. However... Long long ago I worked for a major NAS vendor. We had customers with huge NAS farms [1] and extremely val

One man's ongoing journey coaxing an LLM to write Common Lisp code. Bonus "AI generated" poem by Stanislaw Lem, and a five-paragraph story actually generated by LLM: "The Unspeakable Syntax: A Tale of Lispian Horror.&quo

As another layman, no, I don't think so. The "twin paradox" [1] is a prime example. The two twins depart from a common point in time and space, go about their separate travels, and meet again at a common point in space-time.

You don't really want an agile toilet interface. This is more a waterfall project.

OK, the "typically 10^12 TEC" vs. a +/- 1 TECU (10^16 TEC) disturbance was really bugging me. I think the slide has an error, or there's an apples/oranges issue. The +/- 1 TECU looks to be consistent, but the

Pretty astounding, isn't it? I don't see a paper, but there was a webinar [1]. There's a technical synopsis at 8:00. The phenomenon they're measuring is actually signficant. It's the total number of (free?) electron

The red line is axial acceleration. The rocket rapidly slows to terminal velocity, reaching it at about 25 sec., then continues to slowly decelerate as t.v. decreases as the air gets thicker. [edit: *] The black line is estimated velocity,

For folks jumping on saying "that's not a carrier thing". All comms are a carrier thing. Whether it's ETWS, SMS, or IP, it's going through the carrier, they process it, and they do extensive traffic management. Ca

Totally believable if the debugging device was doing something with a serial port. I once hacked something together to interface a PC serial port to a Raspberry Pi. The PC serial is real-ish RS-232, with negative voltages. The Pi side was j

My most vivid gRPC experience is from 10 years or so ago, so things have probably changed. We were heavily Go and micro-services. Switched from, IIRC, protobuf over HTTP, to gRPC "as it was meant to be used." Ran into a weird, fla

One does not simply walk into RPC country. Communication modes are architectual decisions, and they flavor everything. There's as much difference between IPC and RPC as there is between popping open a chat window to ask a question, and

Ooh, clever. Vaguely envision entropy problems, that some mash-up of Godel's Incompleteness theorem, Maxwell's Demon, and Bell's Inequality, and Newton's laws conspires against it. Maybe sending changes back add entropy,

No. This and all previous flights have intentionlly been barely sub-orbital, with less than one orbit. Launch in Texas, re-entry over Indian Ocean. A full orbit at that altitude takes about 90 minutes; this was over in a little over an hour

I don't think so. That's assuming the program will always be in a frame of reference which is temporally unbounded. If, for example, it fell into a black hole it would, IIUC, never progress (even locally) beyond the moment of inte

As TFA says, they were specifically looking for the effect. It an "HDAC inhibitor." These uh, inhibit the enzyme HDAC, which is known to shut down brain plasticity in adult (mice). As to why they figured that out, some of the st

OK, one more round. An API spec is a contract , not a guarentee of correctness. You, as the client, are free to pass me any data that fits the spec. If my parsing library does the wrong thing, then I've got a bug and need to fix it.

We're in general agreement about the purpose of unit tests. I disagree on a couple of points. Tests do not document the API. No test is complete, and for that reason alone can't completely document anything. For example, a good

Excellent points, violently agree, my question was poorly worded. The purpose of units tests is to verify the contracted API is actually being provided by the implementation details . A clearer question might have been "what are uni

What do you use unit tests for, other than verifying implementation details? Perhaps we have a difference in definition. To me, a unit test for a function such as "parse_news_email" would explore variations in parameters and state
