Late night semi related rant while I can't sleep.

I worked at one place where we had this big distributed system for processing about 1M table rows (recalculate some stuff with latest code to see if latest code has regressions).

I joined a couple years after launch and it took months to get it working okay and have good visibility on it.

It took about eight hours to run, eventually got it down to three. The actual calculations only took like a second per object, so with 24 or so VMs you get the 8 hours. Sometimes it would take too long and the cron would seed the next batch of items in the queue without checking if it was empty, resulting in a process that never finished!

You're probably thinking, just add more nodes! Scale horizontally! We'll, we were on kubernetes. Except we weren't allowed to use k8s. We had to use this abstraction provided by devops AROUND k8s. This framework had some limitations.

Also, simply scaling horizontally would take down the production DB due to number of connections, instead of say using multithreading and reusing connections.

I had a solution that ran through all the data on my MacBook with GNU parallel in less than an hour, but I could never convince the architects to let me deploy it. :)

So, distributed stuff can be really nice. But if you're having trouble building the simple version done well, probably don't make it distributed yet. I might still have PTSD from "hey can you run the Thing on your laptop again? The Thing in prod won't finish for another 9 hours."
1st quess:

Looks like at least one of the engines failed at launch. There was not enough thrust to get into orbit. Automatic shutdown after the rocket was outside parameters.

Oh noes! Should we cancel her for that?

I feel like you're making a storm in a glass of water.

>Certainly doesn't seem like someone I would want to work with either.

But you don't work with her ... so what's the real issue here?

This isn't _large scale_ yet, we only have about 15 services using this library. I'm hoping that now we've stabilised and are spending time on making things structurally better (removing tech debt, improving the tests, rewriting the docs) that will rise.

My tip would be to not worry too much about covering every last detail or feature immediately, aim to do what most people need most of the time and release early - then if there's demand for extra stuff add it as you go.
The key issue is that any use case that sounds legitimate is still not really legitimate because, as a rule, it's illegal to operate a transmitter without a specific license and in almost every case the condition of that license is that you won't interfere with others.

The difference asserted in that quotes is essentially between "willful malicious illegal activity" and "negligent illegal activity", there's no reasonable possibility that it would have been a legitimate use - as far as I understand, simply importing that particular device would already be illegal - there is an exemption in the rules (https://www.ecfr.gov/cgi-bin/text-idx?SID=a230935ff03941152f...) for "Three or fewer radio frequency devices are being imported for the individual's personal use" but that only applies to specific categories of devices and would not apply to that jammer.

Boring Appsec
I'm trying to make the point that the state itself abuses "protected" kids. The living conditions of "protected" kids are horrible, abusive and destructive. Watch a movie like:

https://www.imdb.com/title/tt2370248/

Conditions for kids in state care are little better than a trailer camp. Education in "juvie" is often better than that offered to victims of child abuse (which, yes, causes some kids to commit a serious crime to get some education. Why? It's the only way they can guarantee a placement, or a new placement (because some places in youth services are horrible, EVEN by the very low standards of youth services), or the opposite: guarantee a stop to constant changes in placement). The kids are kept there by force regardless of whether it's juvie or not (which is just one more reason violence is a constant in the life of these kids).

I find it absurd that the government, abusing kids in their care, have the slightest interest in using CSAM detection to protect kids. I don't want to say it, not for all, but for the vast majority of abuse, a kid is better off abused at home. Not because that's good for them. Because youth services and state abuse is far worse than the worst they face at home.

Detection of CSAM forcibly brings more kids into this system and, frankly, it's almost always better to leave them in an abusive family (esp. because most cases are about possession of CSAM, not about abuse of their own kids. Is this ideal? Of course not! Is it better than youth services? Absolutely)

https://sci-hub.se/10.1257/aer.97.5.1583

Without an extreme rise in the minimum standards of care for kids in state care, I am entirely opposed to any and all attempts to detect child abuse. It makes things far worse for more kids instead of better.

And, frankly, I question the intent of people doing the detection. Because every effort just comes down to being one more "trap" for these kids to fall into. Do X (or have it done to you), and you get thrown into the hell that is youth services.

You want to help kids? Care well for specific kids. Adopt them. Make some kids yourself with a partner. DO NOT interfere in the lives of other children unless you're willing to make the full commitment: have the kid living with you, whatever stunts they pull, whatever beliefs they have, whether they accept you or not, for AT LEAST 10 years (ie. until 25 or so).

If you're not willing to do that, there is no form of help those kids need or want from you. Go and help kids with homework in your local school. Help out at a hospital. Whatever.

The OP wrote in Lisp. The Lisp compiler reflects on the code, and realizing that it’s trying all combinations, cross-compiled it to a quantum computer which produced an approximate answer.
Should have posted this on April Fools.

Interesting idea about the non profit. I too would probably pay.
"miserable" mode. It was a mod introduced in vbulletin 2 by community members.

When installed it extended the idea of banning or shadow banning as it degraded the user experience for the person in question. Basically giving the impression that the site was malfunctioning to the point that it was frustrating for the user and they left the site for a while. This included random delays to the page loading, and sending them to a different page and ignoring their intent.

The argument I was replying to is the numbers are skewed by survivorship bias, but given >98% of people survive that's only going to skew the numbers 2% or so not 600% or whatever.

There are no reasonable known lower bounds for knapsack beyond "you must at the very least spend Omega(n) time reading read the entire input".

For sorting too, actually. The famous n log n bound comes from the decision tree complexity, which in turn assumes that only comparison queries can be made ("is A > B?"). However, many domains give more flexibility than just comparison queries, and in particular there are known O(n log log n)-time sorting algorithms for integers (see, for example, https://dl.acm.org/doi/10.1145/509907.509993 ).

While one can come up with contrived domains with arbitrarily large lower bounds (all the way up to computability-centered shenanigans like "sort these Turing machines by how long they take to halt on the empty tape, with ties broken by a lexicographical ordering"), most useful ones not derived from EXPTIME-hard problems tend to have no known lower bound better than just linear.
Geez... those phones are beasts.

I have to agree that the author is somewhat responsible here. Reading it I don't get a strong sense of urgency or ownership.

If this work was important, then why wait on another team who give you a "no telling when" reponse? Get the team together, and assign someone to do it same week. Don't do half-assed follow ups then complain when the dashboard team (which has already shown you it's not their priority) doesn't do anything about it.

If it isn't important, then go focus on the important stuff.
But I think the point is not that they found a chemical that can inhibit CA, it's the idea that targeting CA could be useful. From that point of view, CA dependence really is the "Achilles' heel" of tumors, since tumors (presumably) require vascularization, CA prevents hypoxic regions from acidifying and CA inhibitors will halt tumor growth.

If the initial chemical this team found is not good, no problem, another can be found.

Interesting that I found, on a hunch, that aspirin is also a CA inhibitor[0] (could explain some of its cancer-reducing effect), and further that aspirin derivatives are also promising CA inhibitors[1] (targeting CAIX).

Putting all that together it seems there's a ripe avenue of research for targeting the Achilles' heel of tumors: find CA inhibitors derived from already well-tolerated cheap widely available generic drug (aspirin), and pursue those that are safe and effective in humans. I'm optimistic! :P ;) xX

Surprisingly if you browse HN with "showdead" on, you'll find quite a few people don't realise. Others realise but keep posting comments they know most people won't read (you can tell in some cases because occasionally someone will mention their ban in comments).

(I browse with showdead on because the volume is small on HN, and every now and again you come across people in the former category who were shadowbanned for one or a few incidents relatively far in the past, who since then seem to have acted reasonable, where it's worth pointing it out so they can appeal their ban - mostly the flagged comments or shadowbans are well deserved, though)
In general, they're right. But you have to be careful not to fall into the opposite trap.

Business people and VCs love MVPs and iterative solutions, because they love to sell first and build later. And others have the obligation to scramble and to actually build the solution. So, by all means, evaluate what you are building first. But that is no excuse for selling stuff that you haven't built yet or don't even know if you can build.

Now that I think about it, testing the market and the customer-fit on one hand and testing the technical feasibility and implementing the thing on the other hand are actually both things that salespeople like to skimp on. That's why there are so many half-baked, only half-fitting solutions out there.
Firefox has put some restrictions on scrollbar styling after websites began abusing it for their branding at the cost of accessibility. Other browsers did something similar. I'm not sure if you can even customise the dropdown menu if it's styled by your OS by default, either.

You're right about the missing highlights. Those feel like something not too difficult to implement with a CSS animation and some extra colored borders, so hopefully someone will write a PR for that eventually.
Ok, so you claim rockets in space and change of whole industry to electric cars doesn't have impact on the world for example?
This looks interesting for hacker/gamer spaces, probably also hacker themed pubs, but I wonder if it could be easily adapted to allow the crew to operate their stations remotely, that is, each one at their home.
If remotely networked, it could be expanded to have more ships fighting against each other; the kind of game and related voice communications should suffer less from latency which usually plagues first person shooters etc.

No, you don't get the money back. In theory you should act as if you got the tickets for free. You are going because you find the concert interesting, you do not go because you have already spend $50.

Also you take into account future costs. If you want to go to the concert and there are several days that you can go, you choose to go to the one that you already have tickets. Attending any other day will cost you $50.

Another cost is the social consequences. Maybe you do not want to go anymore, but you know that your mother will be pissed off after she gave you the money. Or you may be judged as irresponsible by your friends if you don't go.

That you paid in the past do not matter anymore. But are there future consequences what you need to worry about.

What about sex toy shops? As small provider selling selected sex toys you constantly face a PayPal and stripe (or whatever) ban. IMO it makes no sense.

Or a portal for prostitutes to advertise their services. I tried forever to find a way to charge CC or PayPal but it's impossible without a huge existing volume. These providers basically enforce a monopoly on this market. Even thought it is completely legal here.

For me the US is enforcing their moral believes on us. In my culture this differentiation does not make sense
Anything within 1 billion light years from us is considered “near by universe”, it’s sometimes also called our local universe.

Tt’s the region of space around us in which cosmic evolution doesn’t play a major factor for observations unlike something that say is 10 billion light years away.

Basically it’s a anything close enough to us that when we observe it we can assume that at least as far as the galactic evolution goes it’s in a current or “developed” state, as in mature and fully formed galaxies.
I don't know the details and they are probably classified anyway. I know about the jammers from a person I worked with as a CS student. This was a project on improving frequency assignment algorithms in battlefield radio networks. We (the university) did the algorithms and they (military) did the reality checks on why a theoretically good assignment doesn't work in reality.
Alright, so in practice Hide my email doesn’t work, the sites you sign up at will still receive your real email. That seems incredibly badly implemented by Apple.

But how can the browser even have your email? Or is Apple leaking in from their systems somehow?
Sometimes it's maybe even good to start with the assumption that if a politician in a large country says that they'll do this and that good thing, because of human rights or religion -- then he's trying to manipulate you
No you don't. You only need to find a combination of toys in your answer that sum to another toy to easily see its not the only possible answer. If your solution involves the duckie for example that can be replaced by buying both the pinwheel and whistle. Or just find another combination of toys that works.
From the article:
“In economic terms, sunk costs are costs that have already been incurred and cannot be recovered.”

It wouldn’t be a sunk cost if if going to the concert was still valued at $50 or more.
That's a... great idea. I had neighbourhood cats decimate my plants when growing them outside, like they would eat not only the leaves but also the buds until there was nothing left.

Had my dog as security but he wasn't always around the plants lol.
I don't find it an interesting problem at all. Generations of mathematicians and scientists discovered secrets of the universe and made calculations without using calculators. 90% of my math tests were done without calculators. Science tests were only about calculating out formulas -- many of which needed to be memorized anyway.

I think you either embrace the technology fully, or you allow only the basic scientific calculators -- something like the Casio FX 240 ($8 on Amazon).

Stop artificially limiting what I can do with a gadget, just because of some stupid exam rule that hasn't applied to me in 30 years.

Oh the average user does very much have problems. They just don't have a place to talk about them out loud. With modern design, people get confused all the time whether something is clickable. Seen that happen so many times I lost count.

> Every single person who starts writing a new application in a memory-unsafe language that will deal with untrusted inputs is declaring up front that they are willing to tolerate the inevitable vulnerabilities and exploits caused by that decision.

Meanwhile we banished Java and Flash from browsers, with JavaScript still leading every pwn2Own contest because these "memory safe" languages are ultimately still implemented by humans paid to prioritize new features instead of security. I still haven't seen a website that absolutely needed multi threading, certainly didn't break anything of note when it had to be disabled as specter mitigation.
If Emacs is an OS, then of course there should be different distributions of it.

That's like complaining that Windows is broken because it doesn't come with MS Office out of the box.

I agree with the point on "Delete your icebox" but I'd argue that this phenomenon exists in other tracking tools. It takes conscious effort to not use icebox/backlog as a wishlist bucket that you want to work on but never have the time for.

That being said, I really like the fact that Tracker encourages you do not get bogged down on small details and overplanning like other planning tools.

I guess the hard part here was to split the work into these small independent chunks, that a single person can work on, and that in the end all chunks can then be joined or replaced. That is where companies rise or fall.
I really did appreciate the post, but I also felt weird about that language. Not offended or anything, but it stood out.

Not to detract from the nice explanation in that post, but I do think "smart" can be a bit of annoying term. It sort of implies an innate property. I'm pretty confident anyone can become really good at anything, given enough motivation and time. I'd prefer the term "experienced" or something to that effect.

I'd like to think, for all their promises of reliability, mobile phone carriers would notice a sudden hole punched in their coverage maps, since they can monitor the signal quality of each device from their central control as they move around the area, and investigate themselves or summon the FCC once they discover it's not natural interference.
