The price didn't fully recover for about a week. (Not sure how to share it, but go to https://www.investing.com/currencies/btc-usd-historical-data and enter 10/1/2013 to 10/9/2013 - based on the prices, it looks like they use Bitstamp for pricing data). I assume they are using an interval similar to what you're desiring - perhaps start of day in UTC or the like

Here's a chart of the immediate drop and rebound, where you see it didn't recover to the price pre-announcement:

My wife has one of the new ones with the "particular" keyboard. I think it's okay (the keyboard), but it's pretty noisy.
> we as modern humans

Most humans had literally nothing to do with this.
I'm pretty sure the more recent, higher-end RPN calculators have lots more than 4 stack slots.

4 is usually enough in practice anyway. Your example is artificial.

Besides, are you sure your infix calculator will accept this deep a nesting of parentheses? The TI models that were contemporary with the early HPs certainly wouldn't!
At least the pollution is more centralized and can be dealt with more efficiently.
I'm still rocking an iPhone 5. I use it mainly for browsing, news apps and spotify. It has the latest OS, all new apps are usable (except games of course).

Recently the battery got swollen, I took it to an apple shop and got a replacement (a refurbished iPhone 5) for 100 dollars.
Yes it's the premise of the article, but I still think it's a strawman.

You can have more or less equality, and equality increasing measures are fairly popular.
Lots of people want to be drones so that they can feed their families. Ideally, they could feed their families without being drones, but your saying that they should be glad to lose their drone jobs without gaining a different means of support is simply cruel.
Roku apps feel pretty clunky/jerky compared to Chromecast and Apple TV. Feels like a product built in the 2000s.
Firing is never fast or easy. It usually takes months to realize your mistake since it takes that long to get up to speed on a new job, And then you have to hire someone else, and get them up to speed. As a result, you're delayed by months, and out months of salary.

Also, firing is terrible for morale. You really can't do it that often.

Failing to hire a good engineer is only a big cost if you can't find a decent alternative hire. If you're paying a 6 figure salary with massive benefits like Facebook or Google, you usually have a long queue of qualified candidates to choose from. Maybe the next guy will turn out to be better than the guy you passed on.

> You will never get a chance to hire them again, and probably all of their friends.

I happen to know that Google gets lots of repeat applicants. They have an explicit "wait a year before reapplying" policy.

I really doubt many people who want to work for these companies decide not to because a friend didn't get the job. That's just sort of crazy.
Nuclear power
Okay. "Loop detected. It terminates conditionally on the value of `a`".

I would think that deciding if a loop halts is equivalent to the halting problem (just wrap your program in a loop). Merely detecting loops seems insufficient.
IIRC, a car engine runs at about 25% efficiency and a power plant usually exceeds 40%.
Code style, inconsistent APIs, a feature that's barely tested by its own contributor, introducing dependencies on innards that were planned to be removed by an ongoing refactoring project, etc. So many ways contributions can go wrong.
It is my understanding that once efficiencies are factored in, electric cars powered by fossil fuel power plants are still cleaner than gasoline for the simple reason that internal combustion engines are rarely running at peak efficiency (efficiency is 0% when idling to use the extreme case), and even peak efficiency is lower than you can get from the power plant. That said, China is also investing heavily in alternative energy, so the situation would only improve over time.
> If they shut down Chinese exchanges, many savvy Chinese will just use international exchanges and trade IRL with paper-wallets.

Except Chinese who are merely savvy, but do not have political connections won't be allowed to transfer significant sums out of the country. Part of the reason for Bitcoin's popularity in China is that it allowed a way around those capital controls.
Best thing I've read about the news: http://www.aaronsw.com/weblog/hatethenews

I read monthlys now. Only sometimes I can't resist checking the daily (or instant) news.
This is an interesting move not only from the environmental perspective, but also the industrial. Depending on how they do this, they could be creating a captive market that pushes demand for EVs to the point Chineese automakers get a real head start on affordable electric car design and manufacturing.
>The cite has some other interesting information. For example, "In 2015, white men represented about 74% of all partners." Remember that white males are only 33% of the U.S. population.

You just brought up the fact that there are few women in the pipeline for IT, and in the very next paragraph you're glossing over the possibility there are fewer non-white people in the pipeline at law firms.

Furthermore, how many of those women fell off the partner track when they had families? You can't put in 70+ hours a week with young children unless you're not spending any time with them. And once you're off the partner track, it's a herculean effort to get back on for a lawyer of either sex.
Whoa there, a lot more went away than 'some shareholder value'. If you put your 40 years in pushing papers, maxed out your Roth IRA and 401k contributions in that wonderful glorious year of 2008 - that went away.
Those people who previously had signed for an ARM with a lender[0] to purchase a home (for which likely had no income to justify a mortgage), when that rate shot up after that introductory term expired-- they certainly lost more than just "some exec jobs".[1]

"the useful bits that remain." Yeah, a bunch of well-financed speculators will buy those foreclosed properties for pennies on the dollar and profit from the other end of that as well. And don't forget, for every dollar that was long on a swap, someone was short and made a damn killing. It's not like that those 30 year US notes were bought back by the government to decrease USD circulation.[2]

I'm right there with you though on your second and third assertions. (Though, on an optimistic note, more companies seem to be side-stepping the standard monopolistic 'approach the standard set of IBs to underwrite your IPO and give them 6% since they're the only ones who have the Rolodex to call up John, his old buddy from Wharton, or Grant his golfing buddy')

There are the equivalent of IRC chats admitted to evidence from a whistle-blower (immunity for amnesty) where Trader A would say "can you plz make sure that __ doesn't go above __ for 2 days? ive got <a position worth about 300 million USD> in <some ISDA product> deep, it'd rly help.. if you can make this work I'll get you whatever you need 50k..100k". (It's been a while since I read the transcripts, but that's the lexicon in which they spoke, and how the transactions were structured internally amongst what amounts to a group of ~100 people. With more or less complete control for the overnight rates for the entire world, they were gaming the system at magnitude so large where kickbacks between other agents would treat 50k and 100k EUR as interchangable.)

Some certainly harmed more than others.

I've never worked at Facebook (so I can't compare directly), but I've never met a Googler who shied away from open sourcing code for legal reasons; no one ever said "I would open source this, but only if I could attach a patent grant to it."

There are plenty of reasons that someone might choose not to open source code (e.g. they like working on only internal infrastructure or don't want to bother with external maintenance), but I don't think the patent grant has anything to do with why a developer at {Google, Facebook, Microsoft} would choose to open source (or not) a library.
They're not banning mining. Miners will be inconvenienced because they will have to sell for dollars overseas and move the money back into China, but it won't be the end of the industry.
What makes a bad hire? Couldn't a 60-70% hire be trained up, rather than expecting all of the candidates to be 90%?
Morality, morality morality, right, wrong, good, evil, bla bla bla... oh and if you disagree with me you should be shamed and ridiculed.

This is just an appeal to the mob to punish those that have a different value system then you. It works because there are enough people in the mob that agree with you that they know the absolute sense of what right and wrong is, that they all will punish those that don't share the same belief system, and praise you for sharing theirs.

So you get that tiny instinctual reward because you have shown yourself to be a valued member of the crowd through upvotes. And you'll also get an instinctual reward due to the sense of power, because those that oppose you are punished get downvoted to oblivion. This completes the circle, and keeps the mob mentality self sustaining. However, no intellectual progress comes out of it, and in fact it makes everyone dumber by rewarding only those who praise the mob.
Thanks for sharing this. I'm looking into Rainforest Trust now and they see to be one of the most credible and highly rated charity organizations (it's always so hard to make sure your donations aren't just bring taken advantage of).
I didn't understand how smart it was until I read your comment!
Why developer evangelism is the secret to the success of Kubernetes
It is cleaner, as the power plants always run at peak efficiency while combustion engines in cars only achieve about 50% of that. So even in the worst case, the electric car is not bad. Of course, an electric car does not have any noxious exhausts inside the cities, nor does it make as much noise as a combustion engine.

But few grids are 100% fossil, and most importantly, most if not all grids are going to get significantly cleaner during the lifetime of the electric car. So electric cars are picking up any enhancements to the electricity production.
If we're comparing with ICE vehicles, an easy way to think about this is how driving style alone can affect mileage. A power plant can be designed and run most efficiently to produce power all the time.

That aside, the fuels used in power plants aren't generally the same as those used in vehicles, are they?
In addition can pollution (Co2, NOX, noise, etc) be effectively de-urbanized.
$20k wine is probably not going to taste any better than $20 wine, objectively speaking. It's just a luxury good for conspicuous spending.
> If something looks like it's an impossibly good investment, it may actually be.

Probably not a fair criticism of the investor in this case. 20 years ago, it would have been a totally accurate assessment.
That misses a key point I was making: OS updates.

Yes, I too have a Nexus 4 (bought in 2012) and it still works fine. But no more updates. I don't consider that on par with say my previous work laptop, which was also 3 years before I upgraded.

I also own a Moto E (2nd Gen, $60-ish) and bought a Moto G+ for my brother this year, but I can't count on them to receive OS updates for as long.
This seems relevant; China are investing heavily in renewable energy:

Interesting. I never knew about that, or had long forgotten. The assertion about the editor being written in Common Lisp is especially surprising; is that true? I never used Lucid or SPE, but I certainly did use Lucid Emacs -- in fact I still use XEmacs daily. Why would they have written a second editor?
The power for electric cars need not, of course, come from fossil fuels at all. Nuclear, solar, geothermic - the car doesn't care. As ever, naturally, workable fusion fixes much...
Freezing I can see being fast and easy. At best you can troll someone by freezing their credit at an inopportune time - which might cause them to lose money, but less likely in general, surely.

Unfreezing? The whole point is to delay access, it can't be fast or it defeats the purpose. "They" have everything they need to unfreeze (otherwise why would freezing be necessary), so the only real protection you have is to forcibly delay access until you can prevent it.
You don't get PM2.5, PM10 and NOX from the tailpipe so less carcinogens in the city.

Natural resources are limited and an increased demand is going to make prices rise especially if the demand goes faster than the supply expansion.

Sleepycat did this https://wikipedia.org/wiki/Sleepycat_Software and seemed to work out for them.

But if opensource truly is infrastructure, why not nationalize it? i.e. government pays maintainers a subsistence wage (provided they meet some scale crtieria, perhaps similar to automatic royalties for pop-song airplay).

Users (i.e. big corporations) would pay a levy to fund this. Of course, it could be set up privately, independent of a government.
What if one leaves the team and the new members find it hard to make any changes without creating a few extra bugs?

Entropy is hard enough to fight, and without documentation or tests, I think, the software is doomed.
Not only are car engines run at sometimes-inefficient RPMs - they also have to optimize for weight, volume, and convenient torques/speeds for a car transmission, all of which come at the expense of efficiency.
Isn't it equally cruel to talk like people want to be drones?

Nobody want to be drones. They are forced into being drones.

Simply keeping those jobs around, merely as an exchange of blood labor for basic living support, is not a mercy to the people you are trying to help. No, it is slaver's talk. It signals a greater failure of the social security network, or the dysfunction of redistribution of wealth to benefit the general public, that people cannot keep basic living standard without such compromise.

Wouldn't applying high taxes also be 'micromanaging'? And why do you think the market, guided by tax changes or not, should decide on how long we keep building combustion engine cars?

If the market wanted to keep them around for a hundred years, until the oil runs out, would that be ok, given what we know about how damaging the emissions from cars are?
Not to mention that EV's powered by fossils fuel power plants provide cleaner air where people are.

Further, a few large plants can better filter particulates and other exhaust more efficiently than millions of smaller engines in every car.
I think the answer is you can solve the halting problem if you have finite memory. You just need to consider every possible memory value. Eventually no new memory values can be introduced, so the next state must be one of the already inspected memory values.

Of course all this takes at least exponential time and so is outside our normal computability assumptions.
The table at the end would benefit from a column indicating the availability of the source code.
thats not what happens in reality. US and China still use tons of coal to generate electricity.
I think you'll agree there's a huge bias in Bitcoin dialog. Peaks are indelible truths, but dips always have asterisks. Let's flip your comments around:

"The price went over $5000 for one day. That does not count as a peak."
"Using the hightest point of the day also isn't useful. Traders typically use a moving average. Neither the lowest nor the highest peak is a useful way to compute the price of bitcoin for the day."
"If you're going to wag your finger and say "Nu uh" and trot out data saying that it went up to X price, well, yes, you're technically correct. But I think most people would agree that the price over the next week is a far more useful way to know whether the price truly went over $4900 or not."
"In other words, if BTC went over $4900 for a day, who cares? No one."

Yet in any conversation of price, that $5000+ ATH is the watermark.
The benefits go both ways.

As a programmer that can work with FOSS software, you have now much more employment options because frameworks/etc. are not proprietary to the company you work for, and you easily transfer your knowledge to another company. If your job is "now to glue free modules together" you are also most likely responsible for a bigger part of the product due to FOSS, which could give you a better position in salary negotiations.

FOSS also gives (not just, but more so than others) developers better non-employment options. As a freelancer, you can more or less choose your software stack and then go hunting for clients, without having to worry about licencing fees limiting your client base. As a founder, you can much more cheaply found a tech-company, because there is much smaller upfront investment necessary, and when started as a side-project can be as cheap as renting a server.

The first time you have to return into python all the gains evaporate.
As I said, we improved python code a few times and it never even got near.
What it did was a bunch of convolutions, dot products, multiplications, fft, gamma probability equations. Even vector comparisons used numpy. Used direct hdf5 interface numpy has and fast view interface for overlaps.

Numba choked on the code by the way and crashed unless views were removed. And then it produced much worse performance.
High taxes still leave some space for innovation compared to a straight ban.
The BGI project referenced above was hindered by certain suboptimal methodological assumptions. It does not appear that the Chinese are any further than the West in the field, and the most notable replicable advances have occurred in the supposedly-stymied labs of the West.

It is worth remembering that China is a highly ideological society with blinders and "PC" of its own, and is not entirely uninfluenced by Western priorities.
Well some OSS is developed by universities and research institutes, which is a form of indirect nationalization.
sure there is ... any centrally allocated system of real or artificially scarce resources based on market dynamics works this way. For instance, radio frequencies, water rights, domain names and ticket scalping. In some municipalities liquor licenses, mobile network providers, broadband, and now marijuana licenses work this way too.

I wouldn't be surprised if banks, cosmetologists and realtors were like this too, but I don't know enough about them.
Well, I read something that I take with a grain of salt and so should you, but here it is:

Those new Nokias are only carrying the brand name under typical chinese design and manufacturing process. The incentive would be to revive the brand in markets where Nokia had stronghold with its cheaper models and the average phone has poor quality. If that's the case it'd be very disappointing for what you are expecting.
I am pretty sure that electric cars are going to take over the car market. Tesla has shown that electric cars can be more desirable than combustion engined ones. They are also the best way to reduce the environmental impact of cars. Currently, the market share is limited by the higher price and more so even by the small number of different electrical models offered. The price does not matter if you cannot get the car model you want in the first place.

So any threats of fossil car sales is about accelerating the switch and push car makers into quickly offering a wider variety of electric cars. As soon as electric cars cross 50% market share, combustion engine cars probably will become less desirable and difficult to sell. So a total ban should not matter too much then, the trick is getting to 50%.

So an entire continent was just a big happy picnic for 60,000 years, with no famine or war? Uh huh.
yeah, exactly that, and the price to buy it for them was probably so cheap (relatively) that it's almost 0 investment
That's a strange view of open source that borders on communism.

You don't have any duties or obligation towards any individual to assist them with their issues.

The only obligations you have is to be honest about the project. For example, if you know that the project is not written with security in mind, you must announce the fact, so that people don't go using the project assuming you took care of all potential exploits.

Beyond that, you have no obligations towards anyone. Quite the opposite. You've already done your part. You donated the product of your effort for free. The obligation is on people who use your product. If they want you to care of their issues, they are obliged to give something back in return. At the very least, appreciation.
> Also, iPhones are extremely economical. My iPhone 6, which cost $749 at the time, is coming up to 3 years old.

Uh, what? I'm on my second ~$70 Android smart phone in eight years. It's a tad slow, but we're talking about literally a few seconds of waiting, nothing truly inconvenient. I have honestly never been impressed by anything a $600+ iPhone can do beyond what my phone can. The only drawback is that it isn't compatible with Apple group texts, but that is more than made up for by the fact that I truly don't care if my phone gets lost or breaks (I back up my files, so I'm only out 70 bucks). I have no idea why people spend so much money on phones.
That's a good way to screw over poor people who have to commute..
> Most new phones are pretty damn good, even the mid range.

For the first week, at least. Then they start to accumulate cruft and slow down, eventually becoming barely usable.

I've experienced it in the past. I see it happen for my friends and family. I decided some time ago to save up that $750 - $1k and go for the high-range phones, so that I can use them for two or three years without daily frustrations.

The top-most commenter is right. Phones are used even more frequently than cars; for many, even more frequently than other types of computers combined. It's one of those things it's not worth to cheap out on - like a mattress or an office chair.

(Now, of course part of me is happy for the mid-range phones costing what they do, because this is why high-end phones cost $1k and not $10k.)
many countries grant pharmacists the monopoly of selling drugs and limit the number of pharmacies per area. This kind of system is used across many fields.

Moreover most big mining operations use alternative energy sources, usually hydropower.
