Maps are models. All models are wrong. Some are useful.
PLenz··on What Happens When Hyperscalers and Clouds Buy Most Servers and Storage?
This is the same argument that mainframe companies made in the 80s. Mass commodity systems will eventually kill the big gpu except for legacy and niche workloads. It's the tech infra circle of life.
PLenz··on Friends don't let friends export to CSV
Everything reads it, everything writes it. CSV is the one true data format to which everything else will eventually be converted to by users.

PLenz··on Fortran vs Python: The counter-intuitive rise of Python in scientific computing (2020)
This is less the difference between fortran and python and more the difference between run once for an experiment culture and run as part of a pipeline culture.

Languages are mostly funglible, coding culutre is not.

PLenz··on Approximate Nearest Neighbor Oh Yeah (Annoy)
The great thing about Annoy is that you can write the index to disk and thus do big data work on tiny workers at the edge. I've never really seen anything else do the same.

PLenz··on Ask HN: Lessons learned from implementing user-facing analytics / dashboards?
No matter what you do, someone will use your dashboard to post-hoc justify a pre-made decision. When it all goes wrong you'll be blamed for making a bad dashboard.
PLenz··on I moved states just before the return-to-office order at Amazon, so I quit
First: It's a power issue. Employment is at will so ceos feel they have more power (or at least leverage) and can say they're firing ypu for a reason. Leases have the power with the landlords so ceos feel they need to be more circumpect. Second: it's a positioning issue. Ceos are usually thinking about their next gig. Layoffs because we overhired: agressive, good ceoing. Too much real estate: bad ceoing, doesn't look great on the next job search.
PLenz··on Ask HN: Are “theoretical” concepts being lost by new engineers?
And then we would move the issue to the licenses. You would _need_ to learn, say, UML when no one actually uses it because the standards body said so.

They're not citizens. They can't vote at all.
PLenz··on A raid on a Kansas newspaper likely broke the law, experts say. But which one?
The search warrant was itself illegal. Hiding behind it is not a valid defense.
PLenz··on Analysis of the data job market using HN job posts
DS was always an overloaded title - speciation into various other titles is ultimately good and indicates a healthy and maturing ecosystem. You still need DS though, in the multi-armed bandit that is your organization your real DS are your explore function - they figure out what to do. The other roles are exploit - they do it.
PLenz··on Chicago’s Railroad Problem
Good read - historically the railroads depended on a system of demurage to make money (deliberate oversimplification alert): this included three pots of money paid by the shipper, one to the originating railroad, one to the terminating railroad, and a per-mile fee to earch railroad that moved the car in between. Railroads could even specialize in different types of traffic, the NKP in the midwest was a mover of fast freights between various eastern and western systems. Many major cities would have a terminal railroad jointly owned by the larger systems who's major job was to interchange traffic between the major roads. Demuragr was a regulated system under the ICC.Come the end of the ICC and deregulation this system changed unit traffic, whole blocks of cars or even whole trains just for a shipper, became more important then single car load demurage system. Infrastructure (tracks, yards, the physical stuff of railroading) changed to support this mainly via abandonment or spin off (the spin offs are usually called shortlines or class 3s). New stuff is rarely built but refurbishment or reconstruction of old infra is fairly common. And all that leads into the situation the article talks about.

PLenz··on Judge rules Wyoming corner crossers did not trespass
New York has a law to cover exactly this - the landlord has to provide acess through the building. This (and other zoning shenanigans) is why so many buildings in NYC have public atriums or plazas attached. Of course many of those are also conveniently locked all the time because the landlords "forget" that they're public space.
