"The speed gap between multiplication and addition has narrowed considerably over the past 20 years to the point where multiplication can be even faster than addition in some chip architectures."

Does anyone have an example of hardware where multiplication is actually faster than addition? That's not an intuitive result unless they're talking about floating point numbers, and even then...
Pretty big difference in situations. I don't recall any country in recent history making such a big move as firing a nuke at the US out of the blue. Not in 1939, 1941, 2002, or 2019.
I create short-lived checklists all the time. For an up-coming food shopping outing, or a to-do list for the weekend.

My favourite ones are for vacations... My wife and I will be taking our son (who will be 5 months old at the time) on his first trip that will require long haul flights (Australia - Vietnam - UK) so I'm currently working on a checklist for what to have in our hand luggage, and a separate one for the hold luggage. For me, it's part of the looking-forward aspect to such a trip, plus there are lots of things that we really don't want to forget, or run out of.

And anyone who's scuba dived will be familiar with the three item checklist that forms part of the pre-dive "buddy check".

* B A R (buoyancy, air, releases) in the UK

* A B C (air, buoyancy, clips) in the US and probably elsewhere

A potential life saver!
@jermaustin1 is right. Nuisance lawsuits rarely go to trial because the cost to litigate is far higher than the settlement demand. Patent assertion entities are usually looking for a quick payout and these cases typically do not last long. Many patent litigators will give you a free one-hour consultation. It does not hurt to ask. (Source: I am a patent litigator, and my firm does free one-hour consultations. I've even done longer ones for free. When you talk to the lawyer, just say that other firms are waiving the cost to discuss your initial options. That is not unusual at all.)
You're right -- it's a bad title, and your constructive criticism is appreciated.
Nothing is perfectly safe. To be clear, I'm not in favor of anyone being held down at gunpoint and administered a vaccine. I'm fine with at least some organizations, including schools, requiring participants to have been vaccinated or have medical exemptions.That preserves the ability to opt out if you are so concerned about the risks but implies certain trade-offs.
CTO's personal experimentation/prototype team? Like mini skunkworks for experiments that benefit from and ought to have zero bureaucracy. That's what I'd ask for if I were high enough up the chain. "give me a 5 person squad of elites and the mandate to point them at anything at all."
It's amazing that you are being downvoted for providing a source explaining the reason for what happened in pakistan/afghanistan. Is it brigading or are people just on a downvote rampage?
I partially disagree.

I completely agree that "trick" questions only select for people comfortable with trick questions. It doesn't hurt if someone who is good at them that is on the team but let it happen organically -- and let it be a non-jerk, which is more important!

I completely agree that coding problems can be excuses for jerks to nitpick, and about the only "good" thing that could come out of such a situation is that the candidate learns that the company employs jerks and doesn't mind them talking to candidates.

However:

The whiteboard can be a welcoming tool if used right. How do you think, how do you talk about the problem, do you actually know the basics?

We use Java, C++, Python and Javascript. We do want you to know one of them. We don't care, in the interview if you forget or misname the name of a routine, or get the arguments backwards (you're not in front of a computer; you don't have to worry about your typing speed, looking up the name, unfamiliar settings on the machine you're in front of, house style etc). We don't care if you forgot a semicolon or even a closing brace, much less a #include. Use whichever language you're most comfortable from the set you'd be using in your job. The best "problems" should be less than a dozen lines, even without any fancy tricks.

We pick something boring, say from the standard library, and nothing tricky like a hash table. Really boring like floor(). If you can't figure out how floor() does its "magic" that's scary. If you need to look up how to balance a tree in place, that would be no big deal so don't put someone on the spot. If you claim to know python but can't print your outputm, that's bad. If you claim to know python and your indentation isn't clear on the whiteboard who cares?

I've told this story on HN before: almost 20 years ago I interviewed a candidate who wrote a routine to shuffle a deck of cards on the whiteboard (we use even simpler examples today). His program ended up elaborately coping the input to the output without shuffling. One of us asked, "Is that really a shuffle?" He said, "Oh I'm a fucking idiot" and fixed it. He was an awesome hire.

At one company we had a standard question (again, write XXX from the standard library) that had a special outlying case. Only one candidate got that, but we hired several people who missed it. Stuff like that can be caught in code review.

But I've interviewed several candidate who spoke well and claimed to know, say, C, but couldn't write "hello, world" in that language. Whiteboard caught it.
I agree. Going back in time wouldnt be too bad. I miss the first days of twitter where i would have discussions with other engs on tech, or days where fewer but higher quality content was the norm.

We probably need a better filter. I stopped using fb years ago, same for twitter. No regrets
One anecdote: My North American math education seemed to focus on rote memorization, with little creative thinking at all. Did you have a different experience? Not sure how they teach math in Japan though.
As if the algorithms behind numerical methods weren't hard enough, now we have to add parallelism :)
Hi! I'm the author of the story and want to note that I only asked Google why it wasn't removing the apps after their investigation confirmed a major policy infraction. By then their investigation was close to a week old.

Google confirmed that these apps were committing ad fraud, and told me that ad fraud is against Play store policy. Yet the company was going to keep the apps in the store. That didn't make sense to me. Fortunately, they reversed their position.

(Also, in case it matters, I didn't submit my story here. But I always appreciate the interesting threads on my ad fraud stories.)
Antihistamines make you sleepy. That's why they are usually on "do not fly if you're taking it" list, even for commercial and private pilots.

Yeah can confirm - OPORD briefs are given in powerpoint with neat graphics and an accompanying paper narrative. Make sure you have the right font and color scheme, though.

They've also picked up the Ex-Motorola RFIC team in Phoenix. Integrating those two teams 9 time zones away I'm sure went poorly. I worked with both of those teams, and they're both sharp. I'm sure the integration was tough, and obviously went poorly.
So it's okay for you to not vaccinate because you have a good excuse. It's not okay for me to skip a historically non mandatory vaccine, nor to advocate for my own right to protect my own life and health.

This is exactly the line of reasoning I'm criticizing. This is the type of ugly argument that radicalizes people with serious health issues who find it beneficial to not vaccinate, but don't have "the right excuse" to make that okay for them.

You were all up in arms at the idea that I was talking about you. You are still being attacking when it's my life on the line here.

There's no actual logical consistency here.

> Amazing that a disease that was eradicated decades ago...

Measles hasn't been eradicated the way that Smallpox was declared eradicated globally in 1980.

Measles is active in many parts of the world that don't vaccinate for it.
Easy answer... cyberstalk them and show off how much you know about their “private” lives.
I really think at this point that it would be more effective for "privacy advocates" to switch gears. Trying to end the war on drugs, legalize prostitution, make the culture more permissive, etc. actually has a chance of succeeding while privacy has only been losing ground for decades at this point.
>I'm pretty sure we want to be very careful about how far we want to go down the path of provide a complete set of vaccination records

Ok, let's move the path upstream then. If you want a passport and/or a driver's license renewal, you need to provide a vaccination record or a valid medical exemption. These are travel documents and I personally wouldn't want to sit next to a measles infested traveler on a plane.

The problem will resolve itself in some years as credentials expire.
The thing is, charities and churches are rarely "run well". Many charities have become a cash cow for their executives and office staff (“Hey, look, we can direct a lot of these donations to paying us extremely generous salaries”), with actual generosity to those in need almost seeming an afterthought. I saw this firsthand when I volunteered in the central office of a charity, and it rather shattered my idealism.

Churches have been notorious for either stipulating that recipients act in a certain church-approved way to get aid, or giving charity in the hope that recipients will convert. Either way, it hardly strikes most people outside that religion as "generous".

It is worth pointing to the Nordic countries, where private charitable endeavours have largely faded away with the rise of the welfare state, and even the local churches are happy to let the state take care of the feeding, clothing and housing business because the state enjoys economy of scale far beyond any church’s ability. In spite of the dwindling of private charity, those countries have less wealth disparity than countries fond of charitable activity. Consequently, some feel that charity is a just an awkward substitute for a functional state, not a good thing in itself.
So we can have other options besides Javascript for full stack development? It makes more sense to have a server-side language that runs in the browser than shoehorn a niche programming language made for web browsers into a general purpose server-side language.
Ask HN: Who is running full Bitcoin or Ethereum node these days?
Given the current size of the complete blockchain for BitCoin or Ethereum, who would be able to afford to run the full node these days? I know that I can't. It almost feels that one would need to purchase a specialized hardware which would not be chip, just to be able to run the node. Isn't this by itself defeats the purpose of blockchain?
And it's not getting any better over time -- it's only going to get worse. Does the size of these blockchains jeopardizes the future of these cryptos?

This article is fantastic, thanks so much. I kid you not, I was already planning to learn about DP tonight and then I saw this article and I'm done! I get it.

The tricky part to learn, and one that I'm sure comes with experience, is how to identify the subproblem + recurrence relation. One thing this clarified for me is the construction of the grid and how it is dependent on inputs because of the DAG. But you can have a recurrence relation that uses more than two sub-problems. i.e. the DP method for calculating Levenshtein distance involves a recurrence relation with 3 previous values (subtraction, addition, substitution).
Capitalism has become pretty controversial lately, so if I had to venture a guess I would say that's likely why.

Can I ask why you put quotes on 'those with needs'?
Uh....you just responded to someone saying "most of the profits aren't from vaccinations" with the profit for an entire company that provides everything from cancer treatments to diabetes medications to also everything else.

They did call out Gardasil as a major cause of the increase in profits from the previous year, but it wasn't 6.2B by any stretch of the imagination.

With physical consumer products this used to be solved by the distributor and retail buyer chain.

Company makes a product and provides samples to the distributors buyers who then run it through the wringer. If it's crap then they don't order any. If it's 'good' then they'll market it to the retail buyers who place orders if they think they can sell it (and it's not crap).

None of that exists in the 'app market'. If it did then you'd submit an app to a distributor who would notice you're sending private user data to a Chinese website and they'll not only not market it, they'll never touch any of your stuff again.

The downside of that system is 99.99% of apps out there would never get installed on a phone in the wild.
But why would I want the keys I use the most to be all near one another? I find that I type the fastest when I have to press keys that are far from one another. What complicates the Dvorak suggestion further is that I use the same keyboard to type two other languages.

My hands rest where they do because of games, because that's what I'm most used to.
I think the article does't clarify that point, because it says:

Yes it's a tech advert blog post, don't bother.

My personal experience is that there are situations where you want to completely disable swap on Linux. Workstations/desktops with large RAM (16GB or more) can see awful swapping when it comes time to close/restart Chromium/Firefox after long periods of use, and I've seen more than one instance where some large-RAM server application which needed to be completely restarted every 24-hours or more.

Swap is usually good, but not always.

> If you don't have a unique supply chain, then what advantage do you have over a mom and pop discount store?

In the article it mentioned those managers dictate what gets on the shelf and mention how they chase after surprise hit (wax nose hair). It seems they're more agile than their competitors and let managers living in those area decides what products to stock.

Perhaps they don't need a unique supply chain?
I feel the only way you could be against a peanut ban in schools is by:

A) Thinking peanut allergies are some kind of health fad or fashionable illness

B) Thinking consumption of peanuts at school is some kind of inalienable human right

C) Having evidence that a peanut ban at schools doesn't reduce cases of children choking to death in front of their peers
Okay then, let's establish a baseline: What, exactly then, is your reason for skipping vaccination? What is your exact reason? I've given mine for why I have had to avoid some vaccines in the past.

Because as I've established above, people who cannot get vaccines for legitimate health reasons (such as allergic reactions or compromised immune systems) are already protected by the system that exists. Otherwise if you're denying vaccines for ideological reasons: You are threatening the lives of other people for no good reason.
Frankly, it's hard to say. The year before it, we had super gonnerhea scare. Before that the hospital super bacteria scare. Before that, it was the ebola scare. Ever since I'd started paying attention to the news, we have a medical (bacteria/virus/fungi/etc) related scare every few months so I've just learn to ignore it mostly. It seems to come in waves. Now, we seem to be in a medical scare phase with fungi, measles, etc. Invariably this scare will die down and we'll all forget it and a new scare ( asteroids, supervolcanoes, ? ) will take over. Then it'll be climate or AI or social media or maybe north korea or terrorism or whatever is in queue. I've just learned to not care. I'm numb to the incessant fearmongering.
And yet it will only happen when those willing to do so do it.

I'm not saying nothing bad will ever happen - as you say, the will to do it is there.

But I'd much rather deny them the effort of all the people who COULD do it but choose not to.

After all, if you're doing something you'd rather not just because someone else might (or even probably will)...you're not very convincing that you'd rather not do it.
I took a number theory class from you almost 10 years ago, and it changed my life. So, thanks. :)
Miniaturized, cheap, low-power electronics and ubiquitous wireless Internet, plus modern image and audio process/recognition, are the end of it, really. It's over. War's lost as long as those exist, and good luck getting rid of them. Cell phones and giving all our data to 3rd parties who can track us without restriction are making it much worse, but the other tools are there, now. We built the ultimate totalitarian toolkit, and a massive disinformation machine that leaves us even less certain what's "grassroots" and what's enemy action than we ever have been.

We split the privacy atom and no non-proliferation treaty equivalent is anywhere near the Overton window, nor likely to be any time soon.

Whoops.

Drones are susceptible to electronic counter-measures (ECM). As it stands now, Russia has a lead in this field. So, (presumably) has China which is busy buying Russian military hardware in addition to developing its own.

Drones are great for slaughtering camel herders armed with AK-47s and TOW missiles. They're not that great against a tech-parity adversary.

Cool article!
I would posit that most people do care about their privacy, but that most people aren't aware how exposed they really are.

Indeed, well. The average person cares about privacy but they don't understand privacy. I mean, it various ways I probably don't fully understand privacy.

Which is to say, on reflection, that privacy and security are fundamentally intertwined just all the various points-of-entry for the bad guys are intertwined.

And the thing with security is that it isn't a feature and an add-on. In an organization, everyone has to care or no can. And with individuals, the same. A given individual can't expect just AV to protect their security and they can't expect a website by itself to protect their privacy.

Where, as I said above, I'm not optimistic on all these concerns.

Which begs the question, why do we make an exception with vaccines? It seems like vaccines are being presented as completely safe & completely effective by some proponents.

You see nuance in this issue, but then, why are critics of vaccines silenced & ridiculed? I thought "nothing in medicine is straightforward"...

I do not know much about Japanese education system in general (I used translated version of the problems) but from what I observe in their challenge math problems used for admission into selective schools and creative output in other industries like popular mangas, the culture clearly values creativity.

The emphasis on skill mastery is most likely there and popularized in the US and globally by Kumon which might skew the perception somewhat.

The component which I am unsure if they emphasize enough is the understanding of math concepts, which is possibly a strength of American math education relative to Asia from what I see from textbooks for training American teachers.

I would appreciate more insight from others here.

Thanks. I also think people are latching onto the word "device" strongly. I really just meant some form of automation.
Brutal, but:

Either:

1. Do it -- You're ok with this failing and being locked out of academia -- then go for it! Maybe, if it fails, you'd be happy joining cloudera or another placing building notebooks!

2. Do it -- You're on track for paying living wages, both for yourself and future employees, say within 6mo organically, or with outside investment (from your post... you're still before then). Maybe live abroad for a year to further cut down!

3. Go back for a year -- Let it grow a bit more, and push any income you'd have taken to others who are earlier in their career

In both 'do it' scenarios, get ready to pivot/expand to areas that will do a better job of keeping food on the table for your employees families, and to keep failing at it until something works. If you can't stomache that, wait till you can hire someone who will, or keep it as a hobby.
