I'd love to know why the author (I've seen that elsewhere as well) would aim at not writing some plpgsql? Is it for the "tour-de-force" bragging rights? I've found that a plgpsql routine can be so much more efficient and faster to devise; especially with good use of triggers. Executing schema-related logic in "ring-0" is way faster and the transaction guarantees integrity? Isnt guaranteed integrity with some logic "vagrant-ish"? :-)

BTW awesome products Hashicorp, way to go!

Interesting read. I wonder if this is only some bandwidth optimization to throw more hardware at the problem or an actual shift in perspective, ref no NaN/Inf, instead clamps to maxval. Could this introduce artifacts/will math libs need to code around this, or will this enable some new insight?

nice! any iOS clients in the works?

Totally unrelated: has anyone noticed that the bar on the F in the FORD logo ends with an e? It has been like that for a while. I remember reading somewhere that Henry Ford had forecasted that transportation was going to be all electric in the future; maybe related? Anyway, I think the demand for this will take them by suprise, and incidently, CT and Rivian need to get those factories churning quick.

Actually if they can build an Expedition SUV on this platform in short order, they could have another model T on their hands. That little e at the end of the bar crossing the capital F would finally take its meaning! (seriously in this price range, it could be a Panel van replacement for amazon, FEDEX, plumbers etc. A suburban ppl mover would be an absolute hit, I'd buy one in advance. (not a 100$ deposit, and cancel my CT reservation that I'm hoping to convert on to a yet to be announced hypothetical tesla SUV based on CT...)

I tried putting in a reservation in Canada yesteday. I think they got slashdoted. Spinning.... Victim of their success. Maybe they will understand why Tesla does not need paid for marketing?

I wonder if this is legal. I know Apple asks you to disable location tracking when returning devices to them for warranty. This could be abused by terrorists to use the postman nefariously...

maybe someone could have sent him a copy of this film? https://en.wikipedia.org/wiki/Rose_Island_(film)

A bit of hacking, some solar panels, a few stereos, tents, some poker chips, a rock band's visit... how long before the authorities would force him off? How many bitcoins would have he raked? (OK this is thinking different in a slightly hollywoodesque way... still)

cheers!

those that can't do teach, and those that can't teach troll open source devs?

If it would be my univ, I'd send a personal email to the dean. https://cse.umn.edu/college/office-dean#:~:text=Dean%20Mosta....

If enough grads do that, I would expect the university will do something about it, and that would send a message. It's about where the money comes from in the end; (tuition, grants, research partnerships etc) IMO none of these sources would be very happy about what might amount to defacement of public property and waste of the time of people that are working for the good of mankind by providing free tools(bicycle of the mind) to future generations.

There is no novelty in this research; bad actors have been trying to introduce bad patches for as long as open source has been open.

(I posted this on another entry that dropped out of the first page of HN? sorry for the dupe)

I fail to see how this does not amount to vandalism of public property. https://www.shouselaw.com/ca/defense/penal-code/594/

Me thinks that If you hold a degree from the University of Minnesota it would be a good idea to let your university know what you think of this.

congrats on the raise!

SQLite is a really neat thing. I was looking at extensions and how to augment it; you could even add a pg_notify -like feature: https://sqlite.org/c3ref/update_hook.html and have worker processes doing what would amount to out of process stored procedures in postgres (or UDF in SQLite) -- in any language you'd like.

You can only register one callback per table tho, although you could from this callback fire other functions... All in all it's an awesome tool for a project like tailscape, but I think the hackers there went for a flat file.

Personally I'd would love to see in process postgres; a build of postgres that is geared for integrating a set of your threads, and builds the whole of postgres with your app on all major OSs, only listening to the inside by default. For the same reason I'm using nodejs; to be able to run the same code anywhere. I think bundle size would be a minor issue, really, I downloaded Sage9.2 yesterday, it's 2GB! VSCode is 100MB download, and they refer to it as a small download...

cheers! happy coding,

Thank you for this post. I have been interested in rust because of matrix, and although I found it a bit more intimidating than go to toy with, I was inclined to try it on a real project over go because it felt like the closest to the hardware while not having the memory risks of C. The co-routines/async was/is the most daunting aspect of Rust, and a post with a sensational title like the grand-parent could have swayed me the other way.

As an aside, It would be great to have some sort of federated cred(meritocratic in some way) in hackernews, instead of a flat democratic populist point system; it would lower the potential eternal September effect.

I would love to see a personal meta-pointing system, it could be on wrapping site: if I downvote a "waste of hackers daytime" article (say a long form article about what is life) in my "daytime" profile, I get a weighted downvoted feed by other users that also downvoted this item--basically using peers that vote like you as a pre-filter. I could have multiple filters, one for quick daytime hacker scan, and one for leisure factoid. One could even meta-meta-vote and give some other hackers' handle a heavier weight...

I dont know what this does to you, but every time I read a PG essay I get an urge to write. This is a very virtuous habit, that allows one to have continuity.

Thanks PG again for a nicely written arc (pun intended), for the somehow diffuse encouragement to write a log, and good luck with what comes next! (if you come up with an august (both meaning implied, the month and the adjective) clubhouse written in bel with only a text interface, please send an invite my way) :-) cheers, F

my question is: who benefits? Follow the money. About if this hack is true or not: It should have been simple to prove true.

Just show a single compromised article with an extra chip, at least one is bound to show up on ebay? Can three letter agencies round up all compromised hardware in all of America in secrecy?? To this day none has shown up, it's all theoretically true. A compromised sample is worth at least 1M vues on youtube, it's worth real money, yet it remains elusive.

A compromised BIOS update is more likely, a BMC IMPI infected by a trojan thing; the new piece is hinting to that in the FUD. Then again, that should be possible to find in a compromised board on ebay (prolly worth less yt vues since nothing physical to look at), and therefore prove this article is not a hit piece for someone with a short position.

I think WSB best look into this... :-)

Cheers! edit: typo

hello Matt, you might be interested in this: uses binlog to provide 2 way sync to postgres including hard delete detection, using postgres triggers. https://github.com/francoisp/rosettable

check this out, https://github.com/francoisp/rosettable. Uses binlog a reader to call postgres triggers, upon which you can build 2 way sync realtime.

Very nice! Data wants to be free. Please check out this rosettable thing we open-sourced last year, it could come in handy: it allows real time ETL-like sync between mysql and postgres. https://github.com/francoisp/rosettable I've implemented the struts of a framework built around rosettable, with mautic <-> davical as a proof of concept, it keeps a user defined map (one to one, many to one, one to many and many to many) in sync, live, both ways, surviving restarts even if there's been divergent edits on both sides while offline.

I havent released this as OS yet, but I'll put a demo online shortly.

For datalakes, I've also implemented something that could be useful: check out duplexRsync: https://github.com/francoisp/duplexRsync. I'll try to reach out via email to make sure you guys see this.

cheers! best, F

I wonder if the rating would be electric only after a while... I would imagine that the various authorities would create a different license, like for seaplanes and IFR. It would make some sense as mis-managing the fuel-air mixture on a small piston plane can lead to catastrophic failure. (frozen carb for ex)

very nice ! I had been using XDisplay, (wired, Macosx iOS only) requires an app on iOS device and needs a patch once in a while... maybe because Apple was about to come out with sidecar? (API changes?) Anyway this is WAY better! True hacker: hard to build a business out of it, so open-sources it. May the source be with you! Cheers

Looks like a clear case of migration to postgres. A single table with jsonb. You can do indexes on jsonb and a few plpgsql for partial updates, and forget about it for a while.

a slightly different angle, also opensource: mautic

I think Amazon and covid (semi and full lockdowns, local shops closing etc) have exposed an idea that you touch on, decoupling the last mile shipping from amazon/doordash/etc; a market/depots/etc for peered-powered distributed shipping/delivery. I would guess the bulk cost of shipping is the fist and last few miles.

The small business support is a weak angle at best. There is a local small business that is dying/already dead that did just that and more: the local paper. I think History will look back as this and ascribe the craziness of these years to "social networking", and give Apple the white knight--good side, if they stay the course and prevail. I long for printed news that cannot change during the day, and for less influencers on influencing platforms.

this list uses the golden rule: short and sweet concepts, precisely worded.

kudos to Paul for this one. Writing about a very very charged and divisive social phenomenon and putting out a meta-conception that casts a better light in a very adroit, objective angle. True free thinker stuff. This is prolly how enlightened individuals had to softly tread their way also in other times, although one on one and small groups allows more forgiveness and time to practice wording your conception than big bad internet.
