>Why send email at all?

- Old bug tracking system going away and how to use the new one

- New feature added to the testing infrastructure and how to use it

- Changes that affect the build system - requiring people to update their paths, etc.

- Weird bug I'm trying to debug (listing all approaches I've tried so far) (usually sent after consulting one or two people privately and getting nowhere).

>Talk to people in private, give them a call, etc.

This doesn't apply to any of the above. Usually my longer emails are for things everyone in the team needs to know.

What usually happens is:

1. Either the person did not read the email at all and start asking everyone for help when things don't work.

2. They read the email, but did not encounter the problem until a week later. Instead of trying to find the email and reading it, they just go to the author. Thus, the author has to explain things about 5 times (first time in the email, and the remaining 4 to people who did not want to read the email).

Granted, I could have put the information on the wiki and just sent a brief email with a link to the wiki page, but then I'll get people coming to me asking "Hey can you send me the wiki link again?" because they cannot figure out what to search for.

In general, people would rather talk than read. Even technical people. The primary reason people do not read my emails is that I am accessible. They would rather come to my cube, call me or IM me than read an email. This is why I put a minor barrier to reaching me: I'm usually not on IM. My next step will probably be to ask my manager to put my cube on the opposite end of the floor as the rest of my team. If I succeed, I'm sure the rate at which people read my emails will go up a lot. It's not a long walk, but that extra bit of effort will cause most people to try more options before walking.

Yes sometimes I wonder if we’re not 4-d “fuzzy” objects. The fuzz being the range of probabilities (and very small realistically).
Look up the statistics on police officer safety. It is not a particularly dangerous job overall.
Individual beneficial ownership as a criterium would widen your definition only somewhat. Plus you could give corporate shareholders non-voting shares I guess.
The problem is that juries without a minority on them absolutely find minorities guilty at a higher rate than when one or more minorities are on the jury.

As the thread below noted, it's not fair to have historical conditions that produced winners (white men, countries with colonies, etc) and then make things more equal by saying "That's all over" and failing to recognize the results of previous injustice that are still embedded in our lives.

I could have offered other suggestions. I specifically said 'juries that roughly reflect their communities in racial and sexual senses'. I don't feel that's an unreasonably burdensome ask in pursuit of Justice.

I don’t see how that could work generally. Sure, it might be possible to enforce by-laws when making a sale/purchase (but extra obligations would inevitably drive down the sale price), but what of situations in which collateral shares are foreclosed upon, they are inherited, or other non-voluntary transfers of ownership? What if one day they ended up even temporarily in the hands of a government (for example, the Italian government’s property and assets cannot by law by encumbered in such a manner). What then? The chain is broken.
The military often operates on much more restrictive rules of engagement.

Example, where a soldier was criminally charged for shooting a likely combatant in the head, after nearly being blown up by a bomb.

Sports is a zero-sum game. Productive labor is not. The mathematician Paul Erdos used amphetamines to make many major breakthroughs. This was a great benefit for society, regardless of whether he perhaps took a professorship that some less productive mathematician would otherwise have obtained.
This gets challenging when you have solar export and a bidirectional meter. The light blinks for every _absolute_ kWh. That is, you don’t know if that was imported or exported electricity, so you need additional information. One approach I’ve seen is to use current clamps just to work out the difference between what’s coming out of the solar inverter, and what’s going into the house. If a > b then the blinks are export, and vice versa.
This sounds like something you could reasonably crowdfund, while delivering a really useful product.
Classicism is something entirely different.

This is "people who have more knowledge will know more". Just like someone who learnt math in high and middle school will be able to budget better, and even improve their tax returns. This isn't classicism.
Then you don't get to be a cop. Or a soldier.
Do your rules correctly handle ownerships that cannot be modelled as acyclical directed graphs (ACGs) (i.e. ownership hierarchies with loops in them)?
It's still three days if you send money between for example Chase and Wells Fargo, because... Fuck if I know why.
It's great that there's de-segregation and I agree with your sentiments.

On the flipside there's a backlash, in the form of a knee-jerk anti-gentrification sentiment that rapidly escalates on racial terms. Both politically (community board priorities and attitudes) and on the street - there's a lot of hostility towards newcomers.

That one's incredibly complex. What you laud as desegregation, many in Bed Stuy, etc. would call displacement.
I tend to agree with the Austrian school of economics, but this entire article is idiotic, and I'm certain that Hayek would tear it to shreds.
What when ISIS figure out this is the easiest way to terrorize people in US? What are we going to do then?
Luckily the ISIS followers are not so smart... But North Korean intelligence might pull something like this on a much larger scale. And target specific individuals.
> What's full-disk encryption do if Facebook et al are going to funnel the data off your devices anyways?

Since you mention it, full-disk encryption does nothing if your computer is on or asleep, which is the case for most users most of the time. It only works if your computer is off.
I guess it'll be just like the good old days with Firefox 1.5.
Wish that an accessible real-time port was required here in Australia. Best I can do is download the 30minute interval data from my electricity retailer after the meter sends them overnight (or use other hacks like reading the blinks)

>American cops seem like they're all on a hair trigger to kill at the slightest hint of danger, rather than as a last resort when they're truly threatened.

This is generally correct. Police in the US are trained to hit "center mass" so they're less likely to miss and more likely to stop an assailant (I believe the NYPD has a 50% hit rate in a shooting, so police are already missing at least half the time). A lot of the reasoning I've heard from police is along the lines of "we don't know if he's on PCP or something and a shot to the leg won't stop him" which is an utter nonsense way to justify it.
I know a guy who submitted apps with a comment, you get $300 if you can help me with some things. 9 out of 10 times it didn't work. But with 1 guy it worked and he promoted fake apps like this.

Agree that Microsoft would be a plausible buyer. They have deep pockets, have hired ex-Docker engineers such as Jess Frazelle on the Azure team, and are investing heavily in the capability to run Linux-based Docker containers seamlessly on Windows. However, they still need to persuade people to use their stack. Aquiring Docker-the-company is the sort of thing Microsoft would do to buy their way into the market.
Try finding enough people willing to do that. I'm not willing to die with the badge on, so I will never be a police officer. But I suspect that if you ask police officers the same question, many of them are also not truly willing to make the ultimate sacrifice. I'm not really sure what to do about this. Surely many of those who are willing to make that sacrifice are already police officers or other first responders.
> However, I contend that the police should not be likely to kill someone

I'm not arguing that they should. I'm saying that they are, and having knowledge that they are makes the one calling in the threat seriously in the wrong. I can't stress enough, the caller's twitter handle is SWauTistic. They know full well what they're doing.
Funny, this happens often in my neighborhood where people wear pants too big for their waists with no belts.
"Innocent until proven guilty in a court of law."

Unless you are murdered by the police for pulling up your pants.

Unless you are murdered by the police "restraining" you.

Unless you are murdered by the police in your cell.

Unless you are mentally incompetent and are tricked into signing a confession.

Unless you are mentally competent and are persuaded by the evidence (not of the crime, but the evidence that the system is corrupt) that you should plead to a lesser crime.

You have to make it to the court before that little sound-bite of freedom kicks in.
It's changed, but not correct.

Currently, all the units in the 'fact box' are KWh. That
is "Kelvin Watt hours", which makes no sense. You want kWh, i.e. lower case 'k', upper case 'W', lower case 'h'.

Wikipedia has a reasonable article explaining that 'K' is Kelvin and 'k' is the prefix for 10^3:
https://en.wikipedia.org/wiki/International_System_of_Units

Same problem in the footnotes, though MWh is correct, so that's good.
Random, sure. Uniformly distributed? Not sure.

Can anyone explain to me the continued prominence of "Object-Oriented Design" as part of a fundamental computer science curriculum?

It seems to me that the basics of OOP, the kind of things that most programmers need to know about, can be covered in a single lecture or two as part of a general programming or software engineering class. Java-oriented design patterns and general API design seem more appropriate as an advanced/optional offering for students who are interested.

The linked curriculum has 6 weeks dedicated to Object-Oriented Design in the intermediate part of the "core programming" section. It seems like that much time could be spent on something more fundamental.
I'd like to understand e-bike usage from a user perspective. Why does it appeal to a traditional biker to use an e-bike in the city (not talking cross country)? Why not „just bike“ or the opposite as in scooter/e-scooter? How come there is such a big market in between?
Thanks for linking such a useful site. It was interesting comparing the Europe to US rates too.
What about the guy who gave the false address? It seems that he is culpable too.
This is such a cool article. A blast from the past, but so meaningful. All of us need to start paying more attention to security.
There’s more connection to excessive traffic stops than to gun ownership.

Guns are definately a problem, but a bigger problem is the idea that we Officers at high risk so that they can be gloried toll collectors. If you cut traffic stops by 80% and used cameras for speed enforcement, you’d dramatically reduce Officer shootings and attacks on officers.

Train them to be EMTs and paramedics instead. The police and public should not be afraid of each other.
>I didn't have a receipt or anything.

IIRC from my current law course, if you didn't get a receipt (or other proof of transaction/contract) the vendor has no right to your money. You'll get receipts everywhere.

Fraud is rare enough here that it's not much of a hassle, the legal system being in favor of the customer helps too.

Germany has also a rather non-credit oriented mindset, people don't like taking up debts or credit, a debit card is usually prefered by everyone, seller and buyer.
Get the top one if you use this machine professionally. In my opinion, time savings will pay off it many times, even if that'll be 10% boost in performance.
Having more control would be valuable, and thus, more expensive. You will have to pay more in order to have more control, while you could pay less and earn the same.

It appears to me that it will, at least, make more expensive to think short term than long term, and that is the intended incentive of this stock exchange (as you could as well just buy more shares if you want more control).
The death of a single innocent civilian is objectively worse than the death of a single police officer.
I had a similar idea (x) a few years ago, but leading this kind of project is way beyond my capabilities. I'm thrilled to see people try to accomplish this, and you seem to have a fantastic team, congrats.

(x) My first idea was to create a market where you couldn't resell a stock until some (long) time has passed. Pretty much the exact opposite of algorithmic trading trying to pass orders at light speed. Another was to forbid any kind of option (not stock options, options) or any other indirect way of speculating over a stock. The idea was to try to ensure the stock owners that someone wouldn't be able to crash the stock of a company he doesn't have any interest in, just for profit.

All of those considerations stemmed from the 2008 crash of course, and all the irrational behaviors that followed. But i still think there should be a way to provide a "safer" place for business owners to attract new shareholders.
You're already working on some kind of laptop, right? See what usage you get at the moment. Look at the resource activity graph. Are you ever pegged at 100% CPU for more than a few seconds? You'll know the answer from there.
Apparently the USA is behind Norway, Finland, and Switzerland in mass shooting deaths per 100k population [1]. For typical gun related homocides it is most certainly correlated with poverty and education.

Objections to Telegram App, by Edward Snowden
This seems to me to be what happened in the Daniel Shaver case, who was drunk and in his pajamas when police (responding to a report of a brandished gun being spotted in his motel room window) confronted him. He was facedown and yelled at for ~4 minutes before being shot when officers mistook him pulling up his waistband for reaching for a weapon:

https://mobile.nytimes.com/2017/12/09/us/police-shooting-vid...

The officer who shot him was exonerated but IMO, the officer belligerently shouting confusing instructions at him should have faced scrutiny. Instead, he got to retire with a full pension while testifying on behalf of the officer who did pull the trigger.

One trouble is that it's much faster to create fake news than to shoot them down with evidence.

And as we have seen (for example with conspiracy theories), some people refuse to believe no matter how much facts you try to throw at them.

With centralized platforms we might be able to still block the fake stuff and discredit people who post junk, but in decentralized world this will be impossible. People choose who they follow and to which fact checking service (if any) they subscribe.
> And therefore, of all the discussion forums I can think of, HN is the one that is most likely to have a view on censorship that prefers freedom of speech rather than suppression of wrong-thinking.

You appear to be suffering from the misapprehension that "freedom of speech" means "the HN community should tolerate bullshit" rather than "you can't be put in jail for bullshit". The difference is extremely important to many of us.
I've got a 2011 Macbook Air (1.7Ghz i5).

That's a good idea. I don't seem to be using that much CPU yeah... I was mostly thinking about future versions of MacOS that might require more power.
It was some years ago on first or second gen Xeon. Wouldn't be surprised if your new CPU is twice as fast.

There is a vulnerability in PBKDF2 that halved the amount of operations. New libraries make use of it but it wasn't known at the time.

That 15+ seconds would be 1+ minute back then. Assume the first implementations were poorly optimized and that's multiple minutes.
This information does support the claim that the Israeli government submitted requests to Facebook. I wonder if Facebook publishes information on how many requests each government makes.

Aside: It's funny the article says Tel Aviv submitted the requests, when the office is in Jerusalem http://www.justice.gov.il/ContactUs/Pages/default.aspx. Subtle.
High level of stress and anxiety will do that too.
Pension is something we should all expect at 50? Really?
Whenever I had to go to the bank for whatever reason, I would check out the teller's desks while they were working on my transaction. It passed the time, but it was pretty interesting.

At least at that time, at that bank branch, a typical teller's desk included: 1 Dell desktop and accompanying monitor, 1 automatic bill counter, 1 desk calculator, 1 check reader, probably a few pens and some with cute designs on them, a few stationery holders for various slips, forms, notices and marketing materials.

All in all, pretty boring affair, but near as I can tell banks are basically stuffy offices from the 80s. Just swap out the Dell for I dunno, an IBM PC or an Apple //.
Yeah, I thought not.
I'm not sure about 6-7 year olds, but in my experience most toddlers walk like that while barefoot naturally.
Our rules follow existing SEC rules for beneficial ownership; they tend not to take a very CS-centric view of things :)
I would go further to say that the second amendment failed so miserably that if you shoot a police officer in self defense (such as in the case of the article), it is game over for you. You either won’t see the light of day again or be put to death. They’ve essentially made acting against the establishment _so illegal_ you’d be crazy to even try.

By merely being engaged by a police officer, you’re dead.
The accusations against Verant Interactive/Sony Online were that the EverQuest was designed to make you get addicted, play endlessly- that they knew what the consequences of these design decisions were.

An example: often bosses would spawn once every K hours- randomly. So you might have to wait a literal 24 hours in a row without ever seeing the boss you need to kill, and he has a 1 in X chance of dropping the item you actually wanted. There were no 'instance' dungeons- the whole server shared that one room with the boss, so maybe you go there to wait for the boss to spawn, and there's two other groups already waiting.

There is a lot about it that was akin to a slot machine and those people who sit and put money into the machine over and over, all day. The same reward mechanism in the brain was being triggered. And from the perspective of players, that waiting, that fighting bosses, all of that was work that you put in to get the reward. And that feeling of putting in work and achieving something- even something that isn't real- that was the addiction when it felt like you couldn't ever get that in real life.

Death in the game was a big deal too- you lost experience, lost maybe hours or days or work. You could lose a level! This triggered really complex fear-of-loss psychology, and for people already dealing with psychological issues (that's why they played EQ so much) there were always stories about the rage from dying. Just really unhealthy stuff all around.

I don't personally think it was designed to do this to humans, no truly malicious intent, but it did mess with people.
To me, this whole article just drips with techno-utopic hubris. The author seems honestly surprised that in its two decades of existence, Amazon hasn't yet managed to reinvent the book. ("If Amazon wanted to, it could with a single act bring a new form of book into being.") Well, perhaps things are not quite that simple. After all, books have been undergoing constant optimization for the past two millenia - never mind decades. It's hard to truly reinvent something that has been successful (and continually improving) for so long.

I'm not against ebooks per se - I own an ebook reader and I think it's great for journeys and the like (though I do prefer physical books where possible). But ebooks are just books on another medium, rather like switching from parchment to paper. They are not the "new form of book" the author envisions. I don't think a book needs all those fancy features he talks about. Sure, they can be pretty gimmicks, and perhaps even helpful here and there. But not everything needs to be, or can be, improved upon by digital technology. A book is a book, and it's been that a long time before Jeff Bezos came along. I dare say it will remain that long after he is gone.
This is explained by the teaching staff having been there for 25 years and no effective process in place to force them to change the curriculum.

It seems like the police is trying to shift the blame 100% on the caller. He might be a terrible human being who deserves punishment, but indeed the sole responsibility lies with the police who pulled the trigger.

But yeah, instead of training for more people skills, let us give them more military-grade weapons.

It's part of a good foundation for measure theory which is part of a good foundation for probability which can be used in any type of computational role. Also, understanding a bit about manifolds, neighborhoods, and things like that are a big part of deep learning theory. I am only acquainted with undergrad topology, but I would say it has had more of an impact on my work and projects and future learning than quick sort ever has or <insert random CS degree topic here>.

Tangentially, it is a great topic to learn in general for those with a math interest and a bare minimum requirement for any higher math learning.

American police and military are trained to shoot for the largest target area, center of mass, as this is the least likely area to have unintentional results.

Some examples of unintentional results are:
1) Missing.
2) Hitting another person.
3) Maming, or otherwise causing grievous injury such as shooting in the leg and hitting an artery on accident when you didn't intend to kill the target.
