Reasons Startups Fail
Your comment is incorrect. There are numerous types of stock. The biggest division being preferred and common. Common entails voting rights, preferred does not. There are also share classes. For instance Google has class A, B, C shares. Class A are what people buy and do entail minimal voting rights. Class B are voting shares owned primarily by the founders and carry 10x the voting rights per share of class A. And class C are voteless shares generally distributed to employees for compensation. Sergey Brin and Larry Page own a minority of all outstanding Google shares (about 13%) but have majority control of the voting power in the company. The same is true of companies such as Facebook and Zuckerberg.

This leads to the rather interesting insight that the current direction and actions of of Alpha/Google/YouTube etc have been ultimately under the exclusive control of Brin and Page; similarly for Zuckerberg/Facebook. These companies' actions give the most honest insight possible into their owners' worldviews. Not the most comforting thought.

As a parisian who stayed in SF for a month last year, i can tell you SF is way better for pedestrians than Paris, without any question (except for the hills of course).

Streets are wide enough that you never feel stuck in a line, there are trees everywhere, and the wind from the ocean makes the air feel very clean.

The reason Paris is spending so much energy thinking about its organization is because it is ( and has always been) completely overcrowded with one of the highest population density in the world. For a city that’s almost 2 thousand years old, that’s an extremely difficult problem to tackle.
Having actual WiFi coverage in the tunnels would be a good start. Now it only works at the stations, maybe for 15 seconds at a time, on each stop. It's awful
I'm sure everyone would be all ears if Zuckerberg were asked for advice on how to best violate people's privacy, or Bezos were asked how to abuse warehouse workers, but there's no reason why the opinions of those two regarding e.g. medicine would be worth more than those of actual specialists and experts.

Just because someone's successful it doesn't mean they're wise. Looking at Zuckerberg fumble from scandal to scandal certainly doesn't give one that impression. He's just another ruthless rich businessman.

> There’s no reason why any PyPI package can’t have meaningful reviews published

You are completely correct. There's no reason at all why any random PyPI package can't have meaningful reviews published. I would go so far as to say that this is true without any changes to the standard library or current processes at all.

With that in mind, I'm thinking about all the various packages my colleages use. I don't think I've seen published reviews for an appreciable fraction of them in any language. This suggests that perhaps enabling reviews might not be the hard problem to solve here.

This thought process also hilights to me that the major advantage of a stdlib is that you have a higher degree of assurance that its contents have seen meaningful review by multiple sets of eyes. It's not just the potential for review that matters, it's the degree of assurance.

I don't know that massively popular utilities were ever "reimplemented" with the same name. Ported, or forked, or extended, but not reimplemented. It's not clear to me if pcp-dstat is a fork or a total rewrite.

I know that moving stack variables to the data section is in fact an optimization that is in use by commercial compilers. It works fine with function pointers. There are two possible answers to the problem of a compile-then-link workflow involving multiple object files.

The first is that the optimization can be limited to within one file. Calls going between source files can sometimes limit the optimization opportunity because it may become impossible to prove that there is no mutual recursion. Functions that may be involved in recursion can not be optimized in this way. One might add a #pragma to override the compiler's determination of safety.

The second possible answer is to have the link phase do the real compiling. The supposed compile phase just preprocesses and verifies syntax.

Function pointers certainly liven things up. Suppose the function pointer of type *X is used to call a function of type X, which then exclusively calls functions of type Y. If we know that none of those type Y functions end up calling any type X functions, then that first-mentioned function of type X will not get more than one stack frame. It is thus safe to optimize with that assumption.

For the first paragraph: I'm not saying no to ads, I'm saying know to wanton abuse of my privacy to provide mistargeted ads when the whole point of that abuse is to provide correctly targeted ads.

2nd paragraph: those ads leverage their context, better than modern "targeted" ads. An ad for a tech product showing up on a tech site is more applicable than a dishwasher. Likewise an ad for a dishwasher on a homeware review site is better than an ad for a computer. The targeting is not providing anything useful.

Final paragraph: you are making the argument that the abuse of privacy is critical to the ad ecosystem, to the extent that in the absence of tracking then the entire ecosystem collapses. This is demonstrably false: when AdWords started it wasn't built on tracking and other such abuses of the end user, it was based on the context of the page the ad is embedded in.

The problem we've got to now, is that the ad networks started pushing "targeted" ads over non targeted to the extent that they have managed to convince everyone that the tracking abuse is necessary.

>while China's expansion into the US went on unrestrained. If this process continued on unchecked, China would definitely replace the US as the world power.

pretty much any projection, from consevative to optimistic implies that China will replace / supplement the United States on a 'several decades+' timeframe, so the aggressive stance taken by the US on a election cycle basis strikes me as unwise. At the end of the century Asia will be the center of the world.

This is one advantage that China always had over the US, politicians in the country are able to think in 40 instead of 4 year intervals. And given that broadened context, poking the bear now simply to delay their capabilities by a few years seems like not such a good idea.

Ask HN: Cheapest service available that captures CO2
Hi HN,

What is the cheapest service available that proposes CO2 capture ?

Ideally I would like to buy CO2 from that service and get a certificate in return.

Thank you!

Not hard.

But boycotting Amazon because of it is selling facial recognition API? Most people will call it nonsense.
That's my preference as well.

I love the Microsoft Universal Mobile Keyboard. The cover of this keyboard also acts as stand for any mobile/tablet device and is magnetically attached to the keyboard, but obviously can be detached and placed wherever you want. Unfortunately the latest iPad Pro 11 redesign renders the stand unusable for the device as it doesn't hold the new iPad Pro securely. Before I was able to use it with several generations of iPads.

I would expect commenters here to have better reading comprehension skills. I explicitly allowed that one could have ethics based on arbitrary consensus.

That said, your discomfort is natural. After all, if the foundation of ethics is purely natural, then what is it? Logic perhaps? What logic tells us that murder is wrong, when logically murder is sometimes advantageous? Is it science then? What science tells us that rape is wrong, when evolution tells us fitness is propagating genes? Then is it aesthetics? Are goodness and beauty the same? Or is there an objective standard of right and wrong that isn't dependent on any human being's whims or self-interest? If so, what is its source?
Why do you think it is the worst? If you don't consider Python, what would you then think is the worst?

Genuinely curious. I use Python daily and I rarely encounter problems with it. There is some getting used to in the beginning, but I went through a similar phase when I started using npm and cargo as well.

What I can say is that I had to go through a lot of experimentation myself to arrive at the tools I use now (pyenv + Poetry). And if anything, maybe the lack of one way that is adopted by everyone in the community is the problem.

If someone wants to pay you to do something immoral, then that means that you're the best/cheapest/some mix of that they found. If you refuse, you make an immoral act more expensive or reduce its "benefits".

That can be enough to reduce the cost/benefit ratio far enough that your potential customer does not consider it worth it anymore. If it does not, the next best option also has the option to refuse, and so on. Even if the immoral act eventually gets done, you have harmed the immoral actor, thus reducing their ability to act in the future -- and it's likely that you wouldn't approve of their future actions either.

The Bloomberg article exacerbates the bigotry many Japanese have against their own fellow citizens. In the caption of the first picture: "She’s not all Japanese, but she was Miss Universe Japan 2015."

Yes, she is "all" Japanese. She grew up in Japan, with her Japanese mother, attending Japanese schools. This is the subtle bigotry toward people who are "half" (as they're called in Japan) rather than "dual". Many Japanese will always consider them "less Japanese" or outsiders.

She had dual citizenship because of her father. When asked which citizenship she would she would choose, she said,
「もちろん、日本を選ぶわ。自分では、私はとことん日本人だと思っている。そう、１００％日本人よ。肌の色の違いは、その人となりとは全く関係ないはず」

"Of course I will choose Japan. I think of myself as thoroughly Japanese. 100% Japanese. It should have nothing to do with heredity, with a different skin color."

We can't substitute water for anything, though. Hundreds of millions of people will lose their water, won't adapt to that, and will move to the northern hemisphere which holds the vast majority of the world's surface level fresh water, or they'll die trying.

No day tickets. A return from a suburb to Center is around £8.

Compared to say, Kentish Town west to Kew for £2.50. The TFL caps are great.

Because your random truckspot has way lower throughput than any major port. You absolutely can do a full freeze-and-search on a German Autobahn (and it regularly gets done to check for driving clock records, overloading and insecure fastening of load), but in a port? No way. Only thing that's remotely practical is to check 1 of N containers with a drug dog or an x-ray and that's it.
At least on certain lines, if you lean on the doors, emergency brakes will be applied, regardless of whether the train is in a tunnel or not.

> what battery can you hold in your hand that can output 50W?

Batteries used for drone racing can easily be held in your hand and can put out hundreds of watts.

Most flashlight and laser pointers use 18650 batteries. Something like the Samsung INR18650-20S can put out ~100W from a slightly bigger form factor than AA batteries.

As I wrote in the second paragraph ("cynicism level a bit darker"), it would be impossible for rewards to outbid transaction fees anyways, because the latter can be inflated in plausibly deniable cooperation between launderer and bank: slap on some bogus insurance, the 24 hours on call special and that outrageously expensive package that would in theory allow to summon a clerk being flown out to your yacht. All understood, on both sides, to be specifically designed to increase transaction fees to make turning a blind eye worthwhile. Money launderers know everything about reading and writing between the lines, it's basically their job.

Banks would still just catch the small fish who shop around for the lowest rates like a regular person. In the end, sibling comments about snakes and hazards are right.
