prpl··on Data centers in space makes no sense
yeah if you want a heat thruster
prpl··on Banning lead in gas worked. The proof is in our hair
There will continue to be new gas plants as long as there are coal plants which will be converted, usually around the time a major overhaul would need to be taken anyway.
prpl··on No knives, only cook knives
I assume he also meant the Alameda Antiques Fair as well.
prpl··on How Google got its groove back and edged ahead of OpenAI
Google, as a company, is easily ahead even if the model isn't, for various reasons.

Their real mote is the cost efficiency and the ad business. They can (probably) justify the AI spend and stay solvent longer than the market can stay irrational.

prpl··on Lessons from the PG&E outage
I suspected this. They were moving, but randomly to an observer. I’d seen about 2 out of maybe 20 stopped Waymos navigating around Arguello and Geary area in SF Saturday at 6PM. What was worse was that there was little to no connectivity service across all 3 main providers deeper in the power outage area as well - Spruce and Geary or west of Park Presidio (I have 2 phones, with Google Fi/T-Mobile, AT&T, and Verizon).
prpl··on NIST was 5 μs off UTC after last week's power cut
those are GPS based too. You typically would have a circuit you trained off off 1PPS and hopefully had a 10 or so satellites in view.

You can get 50ns with this. Of course, you would verify at NIST.

prpl··on Pricing Changes for GitHub Actions
it's just software.

it changes and you move on.

prpl··on Ask HN: Should "I asked $AI, and it said" replies be forbidden in HN guidelines?
were lmgtfy links ever forbidden?
prpl··on 650GB of Data (Delta Lake on S3). Polars vs. DuckDB vs. Daft vs. Spark
"but now also has a sql engine"

it has had a combined SQL and dataframe engine since March 2015...

prpl··on Asus Announces October Availability of ProArt Display 8K PA32KCX
30 or 32" 5k is what I'd love - maybe 6k at 32
prpl··on Zohran Mamdani wins the New York mayoral race
The minimum wage should easily be 11-13 by any inflation metric you use for the last 40 years, and doubling that for a high cost of living place is reasonable.

Lots of states have state-run liquor stores, even super conservative ones.

It’s a smaller delta than you think.

prpl··on Uv is the best thing to happen to the Python ecosystem in a decade
You generate multiple lock files for each OS/Arch variant. You specify the dependency versions in a different file (may also be in a recipe)

Can you show me someone who has packaged log4cxx in a wheel? Is it in pip?

Arbitrary examples, I know, but I moved a large software that was truly mixed C++ and python project to conda-forge and all sorts of random C++ dependencies were in there, which drastically simplified distribution and drastically reduced compile time.

If I had done it today, it might be nix+bazel, or maybe conda+bazel, but maintaining a world of C++ libraries for distribution as wheels does not sound like fun - especially because nobody is doing that work as a community now

prpl··on Uv is the best thing to happen to the Python ecosystem in a decade
conda (and its derivatives that are also “conda” now), and conda-forge specifically, are the best ways to install things that will work across operating systems, architectures, and languages - without having to resort to compiling everything.

Want to make sure a software stack works well on a Cray with MPI+cuda+MKL, macOS, and ARM linux, with both C++ and Python libraries? It’s possible with conda-forge.

prpl··on Bazel and Glibc Versions
llvm_toolchain or gcc-toolchain or the uber one are all some possibilities
prpl··on Bazel and Glibc Versions
no, you just need a compatible starlit/glibc. you pick an old version (e.g. RHEL8) or otherwise compile with multiple tool chains if you need newer glibc features
prpl··on Trump to impose $100k fee for H-1B worker visas, White House says
Hyderabad is not that cheap for the top 10%, probably closer 90-100k base.

Honestly, even Germany is probably better bang-for-the-buck than Hyderabad, but Hyderabad has the volume and the offices.

prpl··on React is winning by default and slowing innovation
nobody wants innovation
prpl··on Adding OR logic forced us to confront why users preferred raw SQL
Salesforce’s SOQL, like was mentioned with Jira’s JQL, also handles this type of thing _okay_ without explicit joins.

I think “SQL is the interface” even for telemtry is the thing that truly makes sense, but it is messy with logs compared to splunk for example

prpl··on An LLM does not need to understand MCP
A comprehensive solution for

1. A user interacting with multiple MCP servers, behind a gateway (with MCP client support) to get authentication from the user to those servers in some way (OAuth/OIDC, with PKCE, usually, sometimes token exchange), allowing out-of-band auth

2. The same, but built on identity for service accounts/native identity or something, for automation

would enable this. There’s a few SEPs open now around this.

prpl··on Rules by which a great empire may be reduced to a small one (1773)
or engineers from Engineers
prpl··on White House Orders NASA to Destroy Important Satellite
Terrible, but predictable, as part of a continued assault on data.
prpl··on Writing a good design document
Expand, condense, compress, expand, compress.

Then somebody comes along and asks about something specific, so you expand.

Finally they use an LLM to compress after their pet idea was satisfied.

It’s crazy really, we’re just on a never ending rollercoaster here.

prpl··on Writing a good design document
you squander sooo much more time whenever people are not on the same page, or if people are worried you didn’t cover their corner case.
prpl··on Show HN: A high-altitude low-power flight computer for high-altitude balloons
looks like a bunch of NEWBS.

(guessing github.com/NEWBS was taken)

prpl··on Rotring 600 Ballpoint Pen
Graphgear 500 is also excellent, though without a retractable tip. I think those who like the grip of a rotring would prefer it over the 1000.
prpl··on 4k NASA employees opt to leave agency through deferred resignation program
Well, among other things, the Vice President was quite literally a tech venture capitalist with all sorts of tech support (not that kind though)
prpl··on New sphere-packing record stems from an unexpected source
The correct option is to treat such conversations as a protocol with a negotiation at the onset.
prpl··on Vera C. Rubin Observatory first images
Too late to edit - I meant Deep.
prpl··on Vera C. Rubin Observatory first images
That won’t happen for this telescope. It has so many unique capabilities that other telescopes would be shuttered first.
