scrubs··on Ask HN: Two specific Postgres encrypt questions
Thank you for response.

>You are missunderstanding the transport encryption(everything related to authentication and pg_hba.conf) and the encrytion of the data at rest

Correct! My questions perhaps implied one is connected to the other whereas they are completely separate. I could have been clearer.

>it means that indices for encrypted columns become useless and are only a waste of cpu time.

are you saying that blunt-force encryption of all data-at-rest renders indexes pointless? Could you provide more context here?

Cheers

scrubs··on Did my old job only exist because of fraud?
I was briefly employed by a robotics company in the US ... robotics is too nice: glorified if/then/else is better.

The owner was the son of an old school magnate out of PA.

Among other things his line has always stuck with me: "A whale that surfaces is soon harpooned."

The company never made money. I think the whole thing was run as a loss on purpose for tax purposes. I became tired of the head manager/engineer combo (big fish in this tiny, tiny world) and left.

Even they knew this company was never really trying to do anything serious. Strange indeed

This allegedly already put a friend's friend out of business - the owner/operator complained Biden would mess her business up and was pro trump.

scrubs··on User Guide to Model Checking for Industrial Programmers with TLA+
If you interested in formal model checking using TLA+, this may of interest you. In this github repository https://github.com/gshanemiller/tla-examples find,

- tla.pdf - numerous examples

The PDF describes model checking in TLA working through minimal background (fairness, model state etc.), application in TLA, two non-trivial models, and two appendices with reference background on TLA, and its procedural cousin PlusCal.

scrubs··on Why Russian Propaganda Works – and How to Stop Falling for It
The issue at hand is Russia invaded Ukraine. That's a Russian problem.
scrubs··on Alberta to hold referendum on whether to remain in Canada
No, not tyranny necessarily. If it's malign morphing into hate speech, racial or genetic seregation, imposing religion, esp. backed up by state power that's a problem. For example, the US has a senate to balance out the house while at the same time California's take on something cannot be rejected out of hand reflexively as tyranny
scrubs··on Alberta to hold referendum on whether to remain in Canada
Politics? Is it? Or is politics a grand word for whining and adults in a perpetual small world? Law, history are at least more grounded as a basis to argue for or against.

Let's not let politics' meaning become so diffuse it's just free speech by another name. Herein "politics" seems to be too inconsequential for a far more consequential result than cycling out party A for B for a few years would have.

I've half joked before that brexit was the only solution Cameron et al saw left because they didnt have a way to hold Brussel's paper pushers to account. Taking your ball and going home is not bold leadership: it's an admission one's argument and solution is weak.

scrubs··on Alberta to hold referendum on whether to remain in Canada
Ah i forgot that.. that was dumb on fed Canada's part
scrubs··on Alberta to hold referendum on whether to remain in Canada
>If the people want to change them, they absolutely have the right to do so

Not so fast. They are in a union with other provinces ergo they have a say.

If nonetheless in some asinine way they secede, will they take their portion of Canada's debt, and other liabilities?

Won't all other provinces require them to negotiate a border, security, and trade policy? Surely they can't expect to be separate yet equal to BC or even the NWT?

scrubs··on $40K for an $8 knob? The case for a military right to repair
Exactly. The dod was dumb enough to sign the restrictive contracts too. Simultaneously it's darn time the dod gets off their duff and either demands much higher customer satisfaction or tells the other side we'll handle selected repairs ourselves.

It's the enlisted men/women who ultimately have to bear up under their choices: does their equipment work in battle or not? And tax payers to pay. As soon as the dod discovers they have ultimately accountability whence ultimate control things will balance better

And an aside: it'd be awesome if every round didnt cost 500 million+ ... I have recently been depressed to hear we spent a large majority of missiles etc in Iran. Iran? Really? How in the hell are we gonna deal with something serious? (Iran/oil is serious of course .. but Iran isn't china)

scrubs··on Graduates are booing pep talks on AI at college commencements
Entitled? Or something?

Reactionary. At worst young kids are lazy (in selected cases only) and nieve about how work works.

Entitlement comes from mental disorder or growing up in affluence like much of the upper 5%.

Moreover, kids from middle to lower income brackets i think work harder, are more resilient, and take their education more seriously than those that just fall in Harvard. The underlying difference? Consequences in the real world. When you always land on your feet or feel untouchable entitlement is 6 months away to a lifetime of clueless.

scrubs··on Donald Trump and sons to be 'forever' exempt from tax audits
Yes. Caught that too. In oth3r places ive read pending claims. This doesn't eliminate future claims nor revoking this deal as illegal.
scrubs··on Remove .zig Files from Bun
Im learning zig for kernel bypass packet work. Aside from some noise, and one bug filed on cross compliation (prob simple to fix) bug, it works like I expect. Export of zig code to clib works fine. Comptime is great. Compile time superb. Like TB I will import no other modules ... and avoid all async.

But this link has got me concerned. When I get more ibverbs work done ill see how good/bad it is in rust.

In this kind of extremely low latency high throughput work there is hardly any (mostly none) MT data structures. Memory is pre-allocated for one pinned thread. Atomics are not much used either. So rust isn't going to help on design much. But I think rust/c interoperability is worse than zig.

In fairness to zig many of these issues were closed when zig 0.16.0 was released, which is what im using.

We'll see

scrubs··on Google Chrome silently installs a 4 GB AI model on your device without consent
Misguided?

Apt install tells what it's gonna do. That's the standard to measure against.

Corporations have become entitled. Like the op i am sick of it.

scrubs··on What can we gain by losing infinity?
You cannot observe infinity operationally. Take 0 and add 1 repeatedly. For what n does n+1 become infinite? Never. Since you can't construct infinity you can only believe in it like God.

Hence the jargon "completed infinity". Semantically --- but not in the symbols themselves 0+1+1..." one can pass from finite to infinite by arguing since every n has a successor define Z to be the set of all successors "completing into infinity".

Not having infinity is the real reason a+b=b+a can't be proved in ultra finitism. Induction which depends on the idea of completed infinity is what is otherwise is used.

scrubs··on California high-speed rail price tag jumps to $231B, nearly 7x 2008 estimate
I don't think unions are the primary problem. Maybe cal can use immeninent domain to get land for tracks. $231 billion is a stupid number whatever the goal.
scrubs··on Trump Administration Will Pay More Energy Firms to Cancel Wind Farms
The trump administration is the most egregious stuck on stupid government in the 21st century so far. To reach this level of radioactive skank on parade, the US (which includes me) had to fall well below what used to be our own standards.

You know what'd be great foreign policy? 100% energy independence preferably trending green. And thereto no more mideast wars. Or if we do get into one (and if our hand us forced), we no longer have to have one hand tied behind our back because of global oil markets, or the hormutz straight.

Allegedly a Spanish gov official quipped: every time the US helps other countries with democracy, it lucks out and finds oil. There is some truth to that.

scrubs··on Can AI be a 'child of God'? Inside Anthropic's meeting with Christian leaders
Absolutely! When you're hawking linear algebra to christains through the back door of "serious question: can or should AI be saved?" ... it's completely and irredeemably stupid.
scrubs··on Can AI be a 'child of God'? Inside Anthropic's meeting with Christian leaders
You way over thought this. Talking about AI accepting the Lord ... is angles dancing on a needle.

It's talk by people with nothing serious going on. It's cheap, pointless pontificating.

scrubs··on Author of "Careless People" banned from saying anything negative about Meta
You make a good point; I agree.
scrubs··on Author of "Careless People" banned from saying anything negative about Meta
America doesn't own greed. Hardly.

But like the movie American Psycho the American presentation of greed is starkly in your face ... it's something horrifying to see

scrubs··on Author of "Careless People" banned from saying anything negative about Meta
Well absolutely. Half the times we're tough on kids is in hopes they don't permanently turn into adults their behavior reminds of

And as kids learning from adults (although the subject matter is different) is exemplified in To Kill a Mockingbird.

As of today I am periodically embarrassed to be an American. Periodic in the sense that every once in a while the shameless behavior of elites feels like I ok'd in the presence of foreigners. Today's climate reminds that in our society i guess as always the suck-ups, butt kisserers, and hustle at all costs is alive and well in the top 10% of society.

Relatedly, this is ultimately why European courts went they way of the dodo. Moody kings, palace intrigue, the maneuvering for kinship to power, the gossip, the scandals whilst spending stupid money so aggravated people we quit.

I seriously dislike this current environment. And I can report not everybody is that way. They're still a few classy lads and ladies out there... but gosh the players are no longer afraid of sunlight at the same time

scrubs··on Why the US Navy won't blast the Iranians and 'open' Strait of Hormuz
We (the US) probably spend too much per munition and do not have manufacturing capacity like China. We're not helpless, but i dont get the sense we have plenty of stock either. Both are problems.

(1) In this back and forth I'm surprised mines in the straight are not mentioned.

(2) im having difficulty seeing how cheap drones incapacitates a carrier. They are there to project force well into enemy territory for precise strikes. The carrier can be some distance from the shore. Now, the question turns to strike what? Surely drone manufacturing plants and barracks would have to be on list or ... they'd be less effective.

(3) if drones are sub-mach speeds why not shoot down with a glorified gattleling gun as opposed to expensive missiles or lasers?

scrubs··on After 16 years and $8B, the military's new GPS software still doesn't work
Sometimes I think the US federal government has too much money. The management function is to say yes to resources in set A and no to everything else. Now, if there's too much money so |A| can grow quite big, you don't have to be good at management anymore to pay for A. Same thing on munitions. Does every damn thing need to be $100k+? Maybe the Pentagon needs less cash.

Our ability as Americans to run large complex projects sucks apart from nasa and a few national labs.

scrubs··on The Many Roots of Our Suffering: Reflections on Robert Trivers (1943–2026)
Wow! This was a fantastic read! Not only well written, it's all brand new to me, something to share with my better half who would love it, and describes new viewpoints I had no idea were around.

Sometimes hn is on fire. Thanks for posting.

Yep ... go/zig pkg management has the same benefit compared to c/c++.
scrubs··on So where are all the AI apps?
What you write is for the service provider, not for customers.

I'm interested in customers. I'm interested in business, which has a support and risk dimension.
