Police officers have a lot of discretion and I'm not sure that a camera is always the best way to get preferential treatment within that discretion. It may be legal but in addition to the courts recognizing it as acceptable officers need to do the same. A court decision will not change the perception of recording among officers but hopefully as more people exercise their rights it will become commonplace and not stigmatized by the police.

I told some people that I consider "Mindstorms" the most important book of the 20th century.

Why is that?

Little kids (2 to 4 y.o.) are like scientists. They are curious, and they continuously experiment. The world is their laboratory, and they are having such a blast with it. They build theories about nature, they test them, debug them, discard some, improve others. This cycle is not unlike how computer programs go through.

And then they go to school. And the curiosity and joy is squashed without delay and replaced with the dread of the homework. Millions of scientists replaced every year by millions of little order obeying soldiers.

Can school be different? Can kids continue to be little scientists, and have fun, and learn by discovery and aha moments and by constructing their own internal models of the world? Mindstorms' emphatic answer is that it can, and the recipe is there.

Are we going in that direction? Fortunately, I think so (at least in the US), although I feel that the private schools and the top public schools are way ahead of the rest. I am not fully familiar with the whole education movement of the last 50 years or so, but from a distance it appears to me that Mindstorms is a (if not the) guiding force there.

If you are at all interested in education, I can't see how you can go wrong reading this book.

You ask about science after civilization has broken down, but then also mention after democracy and peace are gone.

If you're thinking of a lawless Mad Max style apocalypse, most likely sciences will be regulated to discovering things that were already known but then lost to humanity. You could see it like the unrest after the Roman Empire fell (the Dark Ages) where lots of knowledge was lost and had to be learned again from scratch.

It is entirely possible that things will still be recognizable as a civilization even if democratic institutions are gone and even if a nation is at war.

There are pursuits of sciences under a monarchy and even authoritarian dictatorships. During time of conflict, science might focus on military technologies (which often have later civilian applications) or on technology to help pacify the population (agriculture, comfort goods, surveillance technologies).
It's hard to be free when you're dead or in prison.

In any case, I don't quite get your point, since I used that to argue against capitulating.
Wow. That's pretty bad.

I have a similar story of inept police and injustice:

I have an uncle who is a real piece of work. A druggie who my great-grandparents adopted, raised and supported until they both died.

One night he was at my great-grandparents house, harrassing them for money and threatening them. My poor great-grandfather, a 71 year old man at the time, called 911. The operator heard my uncle scream something about killing my grand-grandmother. I guess he was coming off of drugs.

By the time the local sheriff's office responded to the call, my uncle Tim was long gone. The only male present was my 71 year old great-grandfather, so the two deputies incompetently assumed he was the perpetrator.

They didn't even let him put on shoes.

They manhandled my poor grandfather. They took him to jail and he slept on the floor of a cell. He was extremely injured, my mother was furious and encouraged him to press charges. But he was a stubborn old man who spent most of his life as a fire-and-brimstone pastor of a church, in other words he was too polite to take them to court.

The pictures of his injuries are burned into my brain. Massive scrapes, his thin skin peeled back. Bruises all over his face and body. The idea of him sleeping on the floor of a cell...absolutely sickening.

He died a few years later, stomach cancer. He was a great man. I miss him.

p.s. I also have a story of that same department doing me great justice, so keep in mind that it was the two assholes who responded, not the entire sheriff's office that was to blame.

Some of those deputies were good people who saved my ass a few times, let me off the hook a few times, etc. I will say that I'm glad to have moved, though.
I didn't contradict myself at all. Speed and price are two separate concerns. One does not imply the other.

Our Slack integrations make it very very easy to create a Slack bot and all the tasks around a Slack bot (i.e. broadcasts, subscriptions, scheduling tasks, human take over). We have very nice features like automatic users profile fetching (and caching) and all the Web APIs actions are implemented. The only drawback is that we have no deep integration for Slack Grid (yet)
I just bought a Volt for this reason. My wife will be able to stay electric 90+ % of the time, but this weekend's 150 mile round-trip out of town and back for her will be stress free. I'm not sure even being in a Tesla would be as convenient since I don't think there's a supercharger directly on the route.
what went wrong: TLDR probably Ctrl-C,Ctrl-V.

(Just to be clear, this is about Zcoin, not Zcash/Zerocash. The two are completely different)

The fix is here. https://github.com/zcoinofficial/zcoin/commit/33796c839f7d4d...
What happened?

First, some stylized facts about ZCoin:

0) ZCoin is a fork of Bitcoin that uses a 4 year old academic research library, libzerocoin, to make anonymous payments using the Zerocoin protocol.

1) Unlike Zcash/Zerocash, the Zerocoin protocol has only fixed value coins.

2) To get multiple denominations, you have completely separate instances of the anonymous currency that just happen to live on the same blockchain as the other denominations.

3) Zerocoin has its own bitcoin like non anonymous base currency. Call it basecoin.

4) You spend basecoins to get zerocoins.

5) When you spend zerocoins, you get basecoins.

6) ZQ_WILLIAMSON and ZQ_PEDERSEN are denominations, worth 100 and 50 respectively, defined in libzerocoin.

So what went wrong?

When you convert a zerocoin into 100 basecoin, the ZCoin code forked from bitcoin checked if the coin was a valid instance of ZQ_PEDERSEN (worth 50 ) not ZQ_WILLIAMSON (worth 100). So you paid 50 for the zcoin,got it into the instance for ZQ_PEDERSEN, but got back 100. Free money.

Why did this happen? Well, it looks like in order to support the multiple denominations libzerocoin offers, the ZCoin developers wrote some code for one denomination and then duplicated it for each remaining denomination. There are five in total, ZQ_LOVELACE=1,ZQ_GOLDWASSER=10, ZQ_RACKOFF = 25, ZQ_PEDERSEN = 50,ZQ_WILLIAMSON = 100.

But on the last one, ZQ_PEDERSEN was not changed to ZQ_WILLIAMSON in a few places. This caused the bug.

Caveat: I have nothing to do with ZCoin. However, I am an author of the zerocoin protocol, libzerocoin, the zerocash protocol, and am involved with Zcash.
I've always had a personal saying to short any story or company that appears on the cover of Time Magazine. The thought being that by the time a movement or company is that mainstream it is oversold.

I'm inclined to stick to my heuristic here. I'm not seeing any scientific basis to these life enhancing approaches. Rather, I see extremely wealthy individuals who are afraid of dying.

Lorenzo de Medici was also magnificently wealthy and willing to deploy substantial capital in an attempt to live longer. Supposedly he ate crushed diamonds on the recommendation of his doctors, before he died.

>They get some cut of the base pricing plus tip money. Idea is they'll come out profitable on a regular basis despite paying to be there.

I'm fairly sure this is also how strippers often work. Pay the house a fee for the night somewhere in the $50-$200 range, and then hopefully make it back in tips and private dances before the end of the evening.

In all three cases - strippers, hairdressers, consultants - this results in a clear and unambiguous motivation to do a good job and provide value to your customers or you lose your shirt.

In a manner of speaking.

I don't think Tesla has any sort of talent edge in the self-driving car space. Their original autopilot was mostly built on tech from MobileEye and from what I've heard Tesla doesn't pay great either, and unlike SpaceX their mission is not unique.

Having a network of cars collecting data is great, but they may not actually be able to collect all of it simply because it is super high bandwidth, whereas those with test cars can stick a rack of disks in the car and collect all of the data.
While there are cases where privacy rights should kick in (your example of private phone calls is a good one), I cannot imagine how an on-duty and in uniform officer doing something in public (where there is no reasonable expectation of privacy) should expect to not be recorded. That officer is armed and dangerous. In some circumstances, is legally allowed to use deadly force against citizens. Abuse of that power has happened to frequently to claim that the officer needs privacy to carry out their public service.
Perhaps one of these [1] in the boot would reduce stress. It gives about 4 miles of range per hour of charge [2], so only for reducing stress, not for actual planned use!

There are some insane performance. I thought memory bandwidth was a limitation, to move 2~4TB data through memory. Then saw it was a cross join of 1M numbers X 1M numbers. 1 million of 4-byte int is just 4MB, which can fit comfortably in the L1/L2/L3 caches. And the output of the 1M x 1M cross join is thrown away; just a counter is incremented. So no 1T results were pushed through the memory.

A cross join is just two nested loops iterating over one array over another. With 40 cores, each handles 25 billions iterations of the 1 trillion. Assuming each iteration takes 10 CPU cycles, a 6GHZ core can handle 600M iterations/second. 25B / 600M = 41 seconds to run the whole thing.

Yes, 1 second is too fast.

Awesome that they figured it out it's the JVM optimized out the no-side effect computation.
There are a ton of laws about what you can or cannot record and what you are allowed to do with your recordings. Some activities you do have a protected right to privacy like healthcare access.

Great comment. I just want to point out the obvious you can believe you're great & be a nice, humble person.

The self-image comes into play when you're trying to act in a certain accordance with what's in your head. If you think you're bound for great things, you'll look for great things to tackle and you won't be satisfied until you're at whatever version of success you have in your head. If your self-image is happy & settled-down, you'll similarly stress over this. Eventually though, you'll probably get what you wanted because the law of attraction is quite real.

When you talk about accomplishment, it's a relative term though I understand you mean money in this case. Self-image is self-directed, and typically comes from a desire, which naturally comes from a lack. You will see many buy into the trap that money = happiness, and they will thus imagine themselves as some rich, successful tech CEO. After that, self-image has to match up with real-world, so work. The ones who truly believe they are will eventually succeed, and the ones with little willpower will fail. This goes for every facet of life.

That's why it's good to ponder "who am I?" because it's actually a step after "what do I want?" If you can see it, you can be it. Some will call it megalomania and others will call it dedication. Without knowing the person intimately, it's hard to understand which it is, but I'm an optimist and lean on the side of most successful people got there through a lot of hard work -- where their self-image was tested again & again.

The truth is nobody can tell you that you are or aren't successful. Ultimately, it's a personal decision and comes down to if your ideal version of yourself is staring back at you in the mirror.

I agree you should be allowed to record anything a police officer does in the line of duty. I'm all for going one step further and requiring all uniformed police officers to wear bodycams at all times. But we just shouldn't set the bar at "if I can see it or hear it I can record it".

Journalists as a rule exhibit next to no ability to analyze or distinguish varieties of what is going on in the areas of (a) meaningful longevity science that can plausibly produce large gains in life span at some point, (b) dumb "anti-aging" industry nonsense, and (c) longevity science that is not in principle capable of useful gains in life span.

They are given the instruction from above to write something about efforts to live longer in order to fill today's news hole, grab the first five things they come across in a quick search of recent news, rank them all equally, and throw them into the blender. Out pops a popular science article. Little to no attempt is made to gain or convey insight or understanding.

Seems like a high bar to pass to have law abiding citizens treated with respect for the law.

Same with getting cops to not be so quick to pull the trigger and default to respecting people's life.

This attitude of absolute power that some American police hold is as much a cultural issue than one of legal semantics. It has to be confronted without being blown off as an attack on police.

The best approach is probably taking a reasoned, most cops are good, approach and focus in on the minority who flaunt the law.

The solution might be via policy (making it easier to fire cops) or training. But thanks to the all powerful unions I'm sure this will be a big uphill battle.

Agreed here. And also when you find a group of friends who want to achieve the same goal as you do, you'll find that those opportunities to improve your impromptu keep growing. For example when competition time comes up. I remember how we would train for those. It's all about getting into it. Once you find the flow you can decide if you want to practice more to perfect it. But otherwise it becomes more or less like a bicycle. You don't forget how to cycle. But the occasional ride to keep you fit will help :D

it's the ultimate irony. It feels like anonymity because you decouple the "get a bunch of BTC" from "cash out to USD", so it's the worst of both worlds.

It's anonymous at first, so fraud can't easily be reversed. But it's "eventually completely public", so people who might want to use it for anonymity are sitting on a ticking time bomb. Eventually, their identities will be revealed.

There's a business opportunity here in the US. It's now clear that the current administration intends to deport every illegal immigrant they can identify. This will reduce the pool of cheap labor in specific industries. That creates an opportunity for automation.

- Floor care. This should have been automated by now. The Roomba and its friends just aren't good enough at cleaning. What the world needs is a good $3000 industrial strength floor cleaning robot. The technology exists [2] but is too bulky. Here's the Swiss version.[3]
And the advanced R&D version, which is not practical yet.[4] This technology is here, almost. Commercial cleaning needs to become one well-paid person and a crew of robots. This is within reach, and now there's an incentive.

- Lawn care. "Mow, blow, and go" should have been automated by now.

- Commercial dishwashing. Pre-inspection, sorting, vision-guided aiming of pressure wash jets, and post-inspection is needed. A robot at the Baxter level should be able to do this.
