I live in Minnesota. My impression is that employee turnover is ~2-3x higher in coastal markets, which I'd expect to lead to (1) less willingness to obtain company-specific/business domain-specific expertise, (2) more fire drills/"we'll fix it later" syndrome as people leave at inopportune times, and (3) more resume-driven development, which in turn means more time spent working with unfamiliar and/or inappropriate frameworks. In terms of intelligence and coding ability there's probably about zero difference on average, but the environment here just seems more conducive to building quality stuff.

Ironically, a lot of the big employers around here still think dev salaries in Minnesota are too high and are increasingly squandering that advantage by bringing in contractors from H1B body shops instead of continuing to develop talent internally.

There is a quite a bit of incorrect economic analysis in this thread and elsewhere. In a rational market the halving should have no impact on the price of Bitcoin because it's a well known event that should have already been priced in.

It's totally possible that the price might go up, but the reason for that rise would be the irrational behavior of other market participants and people should acknowledge that.
It could be improved yes. Earlier I noticed I only split the array into two and not into m pieces. So later went on a tangent on finding the best way to do that. But, I made the test case happy.

Also it says the length of the array is under 1000, so such an optimization is unnecessary.

The point though is that I probably couldn't do the basic solution with a gun to my head, much less an optimized one. One whiff of struggle and I'd panic and it'd be over at that point. I get very good reviews on my work under normal conditions.

Expecting an optimized, "original" work in a watched/timed environment is ridiculous imho. Interviewer is clueless and destined for failure.

I'll keep this link however. Next time a poor interviewer comes to me with similar I'll first state, I don't do 'swordfish' problems. If they insist, I'll challenge them to this one first. :D

As long a s Bitcoin has value, mining will always make sense.

First thing, even if the block reward is zero, there are still transactions fees. We are not here yet but they are expected to be the primary motivation in the future.

Second, difficulty scale proportionally to the global mining power so that one block is mined every 10 minutes or so. As rewards decrease, the most expensive mining operations will shut down, keeping the cheaper ones profitable. An equilibrium will be found.

The last point is a problem as it makes the network more centralized, potentially allowing for 51% attacks.

Exactly. My company, rent + outsourced IT + utilities, etc is around $12,000/mo for 4400 sqft. So $30 per foot.

Problem I have with that is after the dot bomb we were looking at office space and it seemed that the high flyers that threw $$$[1] at their office build outs were all out of business. Where the ones where you had as a friends company, network cables stapled to the walls weren't.

It's not so much the money spent but the thought that those were the guys that didn't have a sense of how to prioritize their cash flow.

What? FDE is all symmetric crypto, long since 256-bit, and I think all AES. AES is extremely well understood, and the threat scenario for FDE is also purely cold attacks so even any side channels are irrelevant. I've never seen any feasible attack suggested even in principle, so I'm curious what you have in mind in 10-30 years. If you're thinking "quantum computers", you've gotten confused. Against symmetric keys those only provide at best square root(n) speed up via Grover's Algorithm, essentially halving the key size space. But 128-bit is still infeasible to search, and it'd be trivial to counter anyway by doubling the key length. It's only against current asymmetric cryptosystems that Shor's Algorithm can apply in principle (if if Big-If an actual scalable general purpose QC can actually be built).

The property binding all zero-sum games together is that the amount of resources contributed to the pot is precisely equal to the amount that is paid out. Because nothing additional is created in a zero-sum game, for every player who wins something from the pot, there must be a loser.

By that definition, most of Europe has UBI and then some ;)

> Is it really that bad a thought that the goal of tech is to finance a society where no one is left without food and basic, decent, shelter?

That's a very US-centric view. Food insecurity is a solved problem in Europe and has been for decades. Basic, decent shelter? How about 450sqft, utilities included and we'll buy you a TV, throw in free health care, free higher education and 400€ a month in cash? Yet still, people will claim that this does not allow for genuine self-actualization because somebody else will have 900sqft and two TVs or a car.

> Why does it have to be a struggle for so many when we can just build tech that covers basic needs.

Because people don't want to be limited to basic needs, they want what they see others having. They want smartphones, microwaves, computers, internet, entertainment, transportation etc. And as society, we still need somebody to actually create all of that and keep it running. Incentivizing opting out of contribution is, from society's perspective, counter-productive, and the more you redistribute, the more you encourage the contributing members to leave.

Consider this: Germany is at or near the top for total taxation of working individuals. At the same time, top salaries for high-skilled workers are significantly lower than in the US.

Say we add some more taxes to redistribute more towards the unemployed and remove the rest of incentive to work for low-skilled workers. We'll increase the number of people opting to not work, further increasing the required taxes on those that do. And we'll increase the earning-gap for high-skilled workers compared to e.g. the US, increasing the reward of emigration for that group. That's a vicious circle and it's going to be hard to stop once it reinforces itself.
For all Bitcoin miners to be profitable, the global reward for mining Bitcoin must be less than the global cost. Since the reward has now halved, I think the electricity spend should also drop by half, but this may already be accounted for since miners have known about the halvening for a while and should have reduced capacity accordingly already.

> Are you saying that it is not allowed on HN to address someone by their name after they have introduced themselves?

We can't make a simple rule about this. Imagine someone posting "Oh my god, Joe Schmoe! We worked together at Acme Inc!" or whatever. That's harmless. But yeah, if you're in an argument with someone - don't go there. In that case it most likely signals personal aggression.

I appreciate that you don't like hypocrisy and posturing. I don't either. But there can easily be distortion in our interpretation of such things online. We have so few data points on each other that whatever picture we receive is mostly how our own imagination has connected the dots; and we tend to fill in the blank spaces with material from our own darker side. The net result is that we end up feeling surrounded by our own demons on the internet - I've written about this in the past: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu.... That clearly doesn't take us to good places, so we need to guard against it.
E) Most miners accept less profits than they had previously earned. Those that can no longer profitably mine shut down, causing a small dip in hash rate.
For complete Bitcoin newbies, it is perhaps worth noting that while newsworthy, this event is not like an earthquake or a stock market crash as it does not come as a surprise to anyone:

This event was (modulo + or - a month) pre-determined from the very first day bitcoin was launched (and so is the next halvening and the one after that).
Yeah, it's that one except with "MAKE MORE CORES", probably back from when Intel was doing better.
I dont believe it is pilot training, but rather Ryanair doesnt always install proper lighting for heavy fog nor do the smaller european airports on the runways themselves. The lack of more advanced lighting on the planes is probably fine for major european airports that have ground lighting rated to a category of visibility, but the smaller airports have a lesser lighting and fewer backups so combined with Ryanair planes the pilots don’t/can’t risk landing. I had this experience in Poland, where a ryanair flight was expected to land in Bydgoszcz but landed in Gdansk instead (without informing anyone in English of what or where we were)

> Nicholson: With scite, we’re working to introduce Smart Citations. These citations provide the context for each citation and its meaning. For example, we want to know whether the citation provides supporting or contradicting evidence – not just the metrics of how many times it has been previously cited, viewed, or downloaded. This allows people to look at a study and quickly determine if it has been supported or contradicted.

We found that most cited articles (58%) are uncited or untested by subsequent studies, while the remainder show wide variability in contradicting or supporting evidence (2- 40%). This sounds bad, but is actually not too different from all scientific articles in general. Indeed, scientific articles on Wikipedia receive more supporting citations than the scientific literature as a whole.

So their "Director of Technical Operations" hasn't even graduated college yet? Hopefully it's just a puffed up title and he's not actually in charge of anything. Not that you need a college degree to be a good technical leader or that young people can't be good leaders but I don't understand how he could really be in charge of tech ops if he's been busy at Stanford.

Debatable. Personally I would not try to do a project that uses wifi on a cell battery. And if you don't need wifi then you have much better options that use low current not only while sleeping (e.g. nrf series)

Ask HN: What’s the deal with executives having a “not” personal office?
I’ve noticed at two larger companies, that I worked at, with an open office plan the each executive would get a conference room just for the executive. They would decorate it, add a couch, remove the large table, and install a mini fridge while still having a desk on the floor, but never spend time there.

Why don’t they call it their office instead of a conference room? We can all see it.
I've met the Neurable guys a couple years ago at a pitch event. I recall seeing a presentation where Ramses controlled a vehicle using the headset as a basic directional input method.

It'll be interesting to see what kind of applications they end up heading towards!

I guess we'll just agree to disagree.
It's pretty genius system if you think about it. Each of these halving events will shuffle the market players because different actors can be motivated by different incentives. If difficulty drops, then it might be an incentive for smaller players to enter mining again.

It's a chaotic system by design which makes it really hard to predict what will happen in the long run.
Elephants are massive, and have a very large number of cells compared to humans, yet their rates of cancer aren't higher than ours. Research indicates that it may be due to TP53, a cancer suppression gene that is repeated a ton in the elephant. I could see anti-aging therapy eventually being used in conjunction with gene therapy to strengthen our own tumor suppression capacity.
It's a little more nuanced than just getting paid half as much to mine. Miners earn income form two sources, a per-block "subsidy" (source of the mining analogy, this is simply materialized and given to the miner), and per-transaction "fee" for each transaction included in a blocks (these fees are paid by the transaction initiator). Only the subsidy is getting halved. I think the long term vision was the fees would be the main source of income, but they've never made it past around 30%, and are currently only about 5-10% of the total reward.
I used some of the lumens that I got through keybase. Mostly because I was buying something online and saw crypto as a payment option.

No, the maintainers have purposely neutered its usability in favor of it becoming a "digital gold" or a "digital reserve". Fees are far to high for common uses, and this is entirely intentional. If you are looking for usable crypto currencies, you should look at Ethereum, Bitcoin Cash, Monero, or many others who have set up their chains to accommodate actual day to day use.
> Since the reward has now halved, I think the electricity spend should also drop by half

I doubt that. Look at the recent oil production issues: despite demand falling off a cliff, and the price of oil following it, production (supply) hasn't dropped anywhere near enough to match the fall in demand. It's basically a game of chicken--keep going at full force, eating your losses, in the hopes that your competitors are weaker and will be forced to fold before you will.

It depends on the size of your sales pipeline; if small or just starting out, a senior/lead should be able to do sales as well but not everyone is good at it. I've done each & both together. Solution design and pre-sales work aren't always compatible due to different turnaround times so prioritisation if being done as a combined role can be challenging.

This is one of those things that "someone must have already done, it must be out there." Thank you for being that person.
YouTube has long been problematic with their removal of content (especially unsupportable copyright claims), but when it comes to this issue I don't care. Facebook and Twitter are still struggling to come up with guiding principles for content moderation and to distribute and standardize them to tens of thousands of moderators, so I'm willing to give them some leeway.

The core issue is: nobody has an expectation that they are guaranteed their (stupid) content _must_ be accepted by a social media platform.

So long as a person can make+host their own website or torrent for the controversial content (yes, I get that this is much higher friction), all that is lost is the _convenience_ to _find_ the content. I'd wager the Anarchist's Cookbook and issues of the ISIS magazines are still bouncing around the internet somewhere, but they shouldn't be available for the average teenager to stumble upon when their crazy uncle shares/retweets it to the world. It's a quick way to empower angst and anti-government sentiment among those who feel powerless (literally the recipe for terrorism).

The only thing I dislike about the removal of this video content is that it gives the gullible conspiracy theorists the "they are removing it because they know it's true!!1!" argument.
