yep. Somewhere, the BBC still has footage of that happening, taken by me for a mini-handcam documentary on crypto.
Disclaimed: I know sweet f-a about cryptography, and was expecting 100% of this pdf to go straight over my head.

On the other hand, why is the author using "i++" in a preamble of a for loop?
That would have been more correct, yes.

I am more interested in the mentioning of "the spirit of the open source" part. Just image that if one day we are in a world that full of all those "open source electronic cars", to me it will just be too beautiful to see.
At which point you are hostage to a UNION, that turns around and holds a $50,000 gun to your head if you break what is effectively a noncompete.

Remind me again how the UNION is the solution to this particular problem?

Unions solve some problems. However, this is an instance where the Union is a problem.

IMO it's an education problem. I used to work in bone density testing and almost universally people were shocked to learn that cola might hurt their bones. Ironically being heavy means higher estrogen levels and a heavier load to carry (which is exercise for your bones) so the effect was sometimes canceled out. But if you don't know that there is a lot of sugar in some beverages, or you don't do the math to figure out how many servings of the "low cal" beverage you're getting when you drink multiple 2 liter bottles a day then you're screwed!

Just like activity trackers can help improve health by improving awareness (and yes, maybe some guilt) I still think any food/calorie tracking technology could help. And remember here we're talking about nourishment for which there is a nearly free and readily available alternative; water.
Only if that person had offspring at some point.
The first thing you want to think about is your product iteration. If you have a crappy app, you will be throwing your money away with any ad budgets you have. If you don't know ASO that well, I would suggest going with someone like Mobile Action. (I don't know the other two, but if they are the same, they are worth taking a look at).
Added this to the post - it's actually even worse. Two steps, no on boarding at all.

I'm the blog author. I'm glad you guys are getting a kick out of my write-up! I'll answer a few of the questions/comments here, and I'm happy to answer any other questions.
Personally, I see nukes as more ethical than patents. You can make the argument that MAD-based nuclear deterrence has saved us (at least so far) from a third world war. Not everyone will agree, of course, but a strong case can be made.

On the other hand, to defend patents, you have to show that there are things on the market that we can buy that would not have been made available to us if not for patent rights. Nobody can claim that patents have saved us from a catastrophic world war by forcing our leaders to find less destructive ways to disagree. About the most you can say is that without patents, some lifesaving medications for some relatively uncommon conditions wouldn't have been economically feasible to develop.

Musk's comparison of patents to land mines is much more apt than comparing them to nukes. Only a psychopath (or a land mine manufacturer) would argue that humanity is better off because land mines exist. Nuclear weapons are a genuine gray area in comparison.
Well I'm saying it tongue in cheek. For a long time I and many others have stuffed JSON in SQL table columns, and I will continue to do so (heck, databases have started supporting JSON as a result).

But every time a developer sees an interesting twist on a piece of technology and goes for it, peers call it a bad practice.

I've been through many cycles like this, and inevitably some time passes, and one day you wake up to see yesterday's bad practices have turned into exciting advancements.

Moral of the story is, ignore the wisdom of the day and go for it, tiger. Stuff that JSON in an SQL table.

That's a great idea actually. However, I think I am not allowed to monetize from it because of youtube's terms of service. For now, I just want as many people as possible to use this little extension and give me feedbacks. I am just happy to serve other people's needs of listening to music :)
Awesome thanks. I really like it.
I’m not sure if you saw it, but the last figure in the post is a spectrogram of the motor under load. I'd say the load results were the most interesting because they revealed differences in the speed control of the different models.
It does seem an irrational consideration - why is 30k BTC (less than $20m) labeled "such a large amount" instead of "irrelevantly small amount" ?

Even for BTC scale, this amount shouldn't be a big deal by itself. $20m or 30k BTC simply is not big in the financial market sense - it's a big amount for an individual or a single small company; but that's not a significant amount at all for supply/demand of any currency with supposedly millions of BTC in circulation.

If reality matches the published BTC market data, then 30k BTC should be a drop in a bucket with no meaningful change to the market. And if that kind of money actually does mean "a dump of a large amount", then the currently popularized BTC market estimates, capitalization, etc are exaggerating reality thousandfold.

The GP isn't mocking the OP's work, just trying to point out it's a total apple and oranges situation.
Ask HN: How do I know if the startup I'm working at is dysfunctional
Background: this is my first job out of college, and I joined the startup ~9 months ago, right when they launched (I'm engineer #2, before me, the founders outsourced the prototype to an offshore team). The company is working on ecommerce/ affiliate model with a small twist

Right now, we have ~1200 registered user, with about 100 active users, and we gained about ~100 users/month. On the development side, we have a straight up waterfall process with 1 hour "scrum meeting" everyday, we have 5 developers right now. We have no automated testing at all, a deployment update every ~4-5weeks, and a tech stack/ jobs advertisement that would look like it's from 2006. A few months ago, I tried to write some unit tests, and I was asked to removed it from git because the CTO doesn't want git to be polluted.

I believe that a) Our rate of growth is too slow, and b) Our development process is a bit less than ideal and c) Fundamentally, something is wrong with our company (at least, from the tech side), from all the things that I've heard and read. However, I acknowledge that startup is far from the pinnacle of engineering, and even the user stats could be misleading. I talked with one of the founders about speed of development being too slow, and he (with a business background) said that from his experience with other startup, it's not slow, with which I firmly disagree. So the question I'm wondering is, how could I judge the state of the startup right now?
Obviously you would do more than just trust a web page as a licence to the patents, but I imagine it would be hard for Tesla to win an infringement case after publishing this. This is no "Sun CEO blogs congratulating Google on android" level of plausible ambiguity.

Looks like thus is c++ as well.
This is good in a way. It's yet another tacit admission of the legal legitimacy of bitcoin by USG. It's not like USG would seize 20kg of cocaine then sell it into the market in an auction!
What happens if this non-profit vanishes, or becomes insolvent overnight? For example, if the founder of the non-profit takes all the USD and disappears? Your cryptocurrency suddenly becomes entirely worthless, and there doesn't seem to be any way to prevent this scenario from happening.

The only viable way to accomplish this that I can think of is to have a large government run the system, not a non-profit. And since you're tying the value of your cryptocurrency to the USD, perhaps having the United States government run the thing isn't a bad idea. Although it's hard to imagine what the US government would stand to benefit by enabling this system.
Nothing stops any company from now going to Tesla, aware that Tesla is open to a highly favorable licensing agreement, and propose just such a move.

If you check out the spectrograms you'll see that there are a lot of different frequencies in the audio. I wasn't sure if the most powerful frequency would be the true rotation rate, so that's why I wanted to have a separate method to check. However, as TheLoneWolfing mentioned, it turns out that the most powerful frequency is indeed once per revolution.
You just rephrased what I said, except that you replaced "person" with the scarier sounding "speculator."
Exactly. Ember is directly inspired by Cocoa, and Cocoa has been using stateful MVC with incredible success for the past decade.
Seeing how there is nothing particularly innovative at Tesla... This is not surprising
I think there was one guy who was trying to get his coins back.
Please don't make everybody appreciate this story of grief. Everybody who is aware of this now is really sorry for Erics loss. We will accept that cancer is bad. We accept that your daughter dying at this very young age is tragic. But we all will suffer loss in our lives, most of us when our parents die.

Making one's daughters death public like this is arrogant und unfair. It lifts his loss over the ones that we ourselves will have to suffer. We are not even allowed to discuss this rationally, because of the strength of the emotion.

I do not support this "movement", hashtag or thing in general, and I feel emotionally molested.

Edit: Happy downvoting. My grandma killed herself at the age of 86 with a plastic bag. I am claiming IngeborgCreamBeige.
What's falsifiable is the theory of value.

With my theory of value, Bitcoin has to collapse. Keynes talked about how markets could remain irrational longer than he was able to remain solvent, but that said, with my theory of value it has to collapse. So my theory of value is falsifiable.

The theory which says Bitcoin is valuable is "its valuable because its valuable". It's not really falsifiable. They say it's valuable because people find it valuable. If it loses value, they'll say it was because people stopped finding it valuable. How is that theory falsifiable? Whether it goes up or down, they can claim they were right. It's a tautological argument.

Gold is valuable because it is useful. It can be used to fill teeth, it can be used in electronics, for industrial purposes etc. Geologists spend time looking for where gold might be, then speculators spend time looking there, and if they're right, miners spend time mining it. As gold has a use, and has been useful for thousands of years, investors have a fairly certain (but not absolute) idea that they can exchange the gold they mine for other things.

Gold does have an inherent value. Compare an ounce of gold to a 1971 dollar. The 2014 dollar is worth a fifth of what the 1971 dollar was. An ounce of gold did not have it's value removed. Gold has an inherent useful value. The Papiermark, dollar etc. depend on the shifting winds of governments. The US government can fire up the printing presses and half the value of the dollar in a few days. You can't half the value of gold as easily, you'd have to make some kind of major scientific breakthrough.
There have been quite a few times that science has confirmed accounts in the Tanakh and New Testament ... large portions of both are dedicated to conveying history regardless of whether you believe in the spiritual aspects described.
Thank you, you made my day. Though in truth, I'm not very brave, I'm single, without wife, girlfriend, or kids, or anyone really depending upon me. And I work for government because I got tired of making rich men richer. I'm an idealist, and an idiot in truth. But thank you.
It would be awkwardly phrased, but he probably meant by that the effect of his submission doing well.

I agree. I've been feeling like we've lost a lot of the pure fun of hacking and hackathons where the prize is substantial or gets you in with a VC orients the thing more toward business and away from just being a fun time hacking on cool stuff.
That would be excessive. But reserving some space in CSS for the memory of the daughter of someone who had a significant impact on the CSS standard is probably fine.

We don't have monuments to every dead world leader in Washington, D.C., but we somehow find room to make a few for United States presidents.

> Last week, Maxim Ksenov, deputy head of Roskomnadzor, took to Russian newspaper Izvestia to complain about an unnamed Twitter account that "published monstrous things" and called for the overthrow of the political regime and the destruction of capitalism. Ksenov threatened to block Twitter entirely unless they "listen to us and periodically remove illegal content."

Wait, so calling for the destruction of Capitalism is illegal now in Russia?

That might be news to the quarter of the Duma who are Communists: https://en.wikipedia.org/wiki/Communist_Party_of_the_Russian...
"We have essentially no patents in SpaceX. Our primary long-term competition is in China," said Musk in the interview. "If we published patents, it would be farcical, because the Chinese would just use them as a recipe book."

Perhaps Tesla relies on trade secrecy as well?
> With my theory of value, Bitcoin has to collapse.

There's absolutely no risk to a vague claim like that. It's unfalsifiable. Either we witness Bitcoin collapse, in which case you made an amazing prediction, or we don't witness Bitcoin collapse, and on your deathbed you can be proud that you haven't been proven wrong yet.

To make a meaningful prediction, name a time (preferably within most of our expected lifetimes) and a market price. Of course, if you could do that with any confidence, you should also trade with that same confidence.
One of the inherent assumptions of neo-classical economics is that we're all selfish, rational, utility maximizing, humans. That's built into our understanding of markets and how they function.

Now I understand where the author is coming from, and I agree there is a terrible lack of trust in modern America. I just don't agree that the cynical view, that all humans are untrustworthy shit-bags, is all that terrible. Cyncism causes parties to make explicit their assumptions about future behavior. We can then codify this assumed behavior in contracts.

If I was a battery manufacturer and I wanted to use Tesla's patents, I would approach Tesla and ask for a contractual agreement whereby Tesla agreed not to use those patents against me. If Tesla were unwilling to enter into this sort of contractual agreement with me, I would assume they were reserving the right to later use these patents against me.
Eric might not be the active agent in this, and I understand the context. Wether Eric feels addressed by this or the person behind the hashtag, I believe that my argument becomes clear.
It's not just those services and apps, it's pretty much anything that has to do with music.

Try rippig classical CDs and you quickly discover how bad the online music registries are at identifying albums, how bad ripping software is at sorting out composer from artist, etc.

In nearly all aspects of software dealing with music, classical is the odd man out. It's a constant frustration.
You can also download a spectrograph app for your smartphone and see it update live. I did that a few years ago when I was getting into a debate online about blender speeds.
Author is very unfair to the "capitalist environment like America's". Our market-driven society requires, and rewards/trains, a level of trust that's less-common elsewhere. Just two data points:

(1) Americans are "The Weirdest People in the World", per one review of psychological studies, in economic games. They're more willing to punish 'unfair' offers in the 'Ultimatum Game', and offer higher shares against naked self-interest in the similar 'Dictator Game'. See for more details:

http://www.psmag.com/magazines/magazine-feature-story-magazi...

(2) We've had a number of explicitly "anti-capitalist" nation-states in the last 150 years. They haven't been paragons of collective action for the greater good, or protection of the common environment. In particular, the ex-Communist societies and emigrants-from-same sometimes take a while to adjust to new economies where every stranger, government and non-government alike, isn't constantly trying to screw them under false pretense of shared-sacrifice.

The actual games in "capitalist America" are only very occasionally dog-eat-dog zero-sum affairs. More often, they're iterated games rewarding not just consciously chosen cooperation but an optimistic, cooperate-by-default mindset. Politics, with its zero-sum elections and redistributions, is an exception. Its partisanship shouldn't be attributed to market processes, but to electoral/governmental ones.
Zapp Payments Hackday in London 7,8 July – Shoreditch, London
As someone who has done lots of work for both EU and US companies I agree. The amount of times American companies just say "trust us" versus EU companies definitely grates on me. The US is not all terrible, but there is tons of work force exploitation going on in the US. Especially in the bay area.
So if we could all just trust Elon Musk and never question anything about him or his companies we could save the environment, and capitalism and our culture and all of humanity?

OK then.
What's not consistent?

Also, it seems that "criminals" are the new "terrorists".

You should also be able to see the speed of the blades (or a multiple depending on how the motor is wound) in the back-emf produced by the motor and fed back out the power cord. I've seen many cases where a sewing machine would produce frequencies that interfered with the horizontal and vertical sync of a television set ... in principle, a blender motor should als be noisy.

The simplest way to test this would be to connect an oscilloscope or spectrum analyzer to the AC power line. This can be dangerous, so I'd recommend capacitive-coupling or for an even safer test, inductive coupling. Capacitors are effective high-pass filters, so picking the correct value will reject the 60Hz power while letting you see the high frequencies produced by the blender.
The last line about China seems extremely unnecessary and inaccurate.

"Stop making your loss public; it's not more important than the losses in my life" is an argument I don't hear often. I can see some merit in it, but it sounds like a counter-argument to functionally any form of public funeral or acknowledgement of death. Couldn't this reasoning be applied as criticism for the funeral of Michael Jackson, Jim Henson, basically any celebrity or political figure, and any soldier who returns from military service in a casket?

You can hold that line of reasoning, it's internally consistent... But it appears disjoint from the cultural values I perceive. Maybe the culture is wrong; in this case, my gut tells me it isn't, but I don't have a good counter-argument to explain my gut. ;)
And part of that is not attacking targets where you're likely to significantly injure yourself as well as your opponent. There's a lot to be said for not punching someone in the jaw.
>As principled as Google's stand was in refusing to pull an offensive video, it probably did more to stifle the free flow of information than had they pulled the "offensive" video on request.

It definitely feels like a lose-lose situation for liberty when governments can pressure websites to censor at the risk of a total block.

Google is currently working on a crowdsourced proxy called uProxy in order to push back against censorship. If uProxy succeeds, it will no longer be necessary to meet censors half way.

They could probably get more value out of the bitcoins by selling them slowly in the market rather than issuing a block sale. That's like Ackman running to the market and yelling for sale 20,000,000 shares of JCP. He instead slowly acquires or divests his stake.
Ok, I'll bite, because I like the Red Dwarf reference in your username.

Yea, I went funny with the scale. Jumped straight from skycraper to something the size of a GSV from the Culture series.
This may be the wrong venue to say this, but the war against proprietary technology and patents doesn't totally make sense to me. I've read about many of the popular cases where large corporations use patents as a legal tactic to stall competitors, and I understand how it hurts innovation.

On the other hand, can't patents protect smaller companies? Open sourcing projects and technology has its case-by-case pros and cons. I agree the increase in open source adoption has had a largely positive impact on the development community. But there seems to be a lot of stigma against 'proprietary' as a whole.

How is your company supposed to grow if you can't protect your technology from being easily replicated by competitors?
