>All bullets yaw and tumble when they hit a person, that is a matter of physics.

exactly. It has to have enough speed for the yawing/tumbling to result in fragmentation. And that is what achieved with modern weapons like M16, AK74.

>The idea that they are somehow specially designed to do that is an urban myth.

For example the 5N7 5.45 AK-74 bullet, the "poison" one, had an air-pocket in front between jacket and the core. We don't know whether it was intentionally designed to enhance the tumbling upon hitting the body - we do know it did significantly enhance it.

>occurs when a bullet that is near maximum stabilization undergoes sudden structural stress.

yep, yaw upon hitting target at short up to medium distance when the speed is still close to maximum.

> That is literally the opposite of trying to make a bullet tumble.

in that in previous sentences you're conflating bullet stabilization/tumbling during flight with the tumbling upon hitting the body. It is 2 different things.

>They aren't any more or less cruel than the cartridges they replaced.

Higher fragmentation and higher tumbling makes them more cruel. There is also shockwave issue from the higher speed, yet it it is outside of the type of effects we're talking about and is a topic on its own.

>US weapon and cartridge re-designs have incidentally eliminated it in pursuit of other priorities.

and as i already mentioned in pursuit of other priorities USSR/Russia moved to more stable round. So at least we have that.
> Well, multiple people have been fired and imprisoned

1 out of 4 initially involved people has been charged. People who did the initial coverup are still untouched. One chief of police was fired by a mayor. Firing someone for helping with murder or current attack on unarmed civilians is a joke and bringing that up will only make people more angry. (Fired cops often go straight into security jobs)

I tend to agree. Part of the problem is when developers get thrown into unfamiliar code bases but can't read code well, they may think about just doing a rewrite.

But really, Thoughtful refactoring is better. And as another comment noted, in many cases good architecture comes from learning by past mistakes of yourself and others.

OTOH, there are edge cases. I'm currently finishing up a rewrite, but it was due to the existing software being written in a language that most people aren't proficient in and isn't really the norm in our company.

I've witnessed but did not participate in two rewrites. In one case, a company wanted to switch languages and databases (got sick of oracle licensing.)

In another case, the company had a pretty good justification for a rewrite; the system was a monstrosity of .NET on top of VB6. In fact, in this case after the initial rewrite attempt failed and there was a change in management we pivoted strategy. Instead of trying to rewrite the world we would just continue to refactor things as we made changes to those modules, and only hard-rewrite the VB6 code. I don't know if they're still doing that, but it was a -lot- more productive than the rewrite team spending a year producing nothing that ever made it to production.
I've thought about this for a long time.

Ranked choice voting and vote out everyone with a party affiliation on either side, the end goal being to take away the majority from both parties at both the state and federal level (and county etc also). After you get that you can start doing things like term limits, reining in K-street, etc.

That's the start to taking back both congress and eventually potus/scotus etc.

Unfortunately many people identify with their party as a tribe and fail to acknowledge the oligarchs own them both. As Chris Hedges says, it's the quiet bipartisanship you don't hear about that's the most dangerous.
This is a fair distinction to point out.

You can also spread the message to your friends and family. That Grubhub, uber eats, etc are not the best way to support a local business, and that they conduct these deceptive tactics.

I’ve had friends in the past week state “I’m supporting local tonight” and then continue on to state they ordered via uber eats.

They’re upset to know, but thankful to be informed, that ordering via uber eats doesn’t actually support local in the way they believe they are.

The whole fake websites / fake phone numbers just adds to the bad taste, supporting local does not align with supporting deceptive middle men.

There is no proof GH added value here. Allow me to share a related story:

In some places in Eastern Europe, for a while, you could see these people stand in front of empty, free parking spots in the street. As soon as they would see a car approaching they would wave their hands and signal you to park there. To be clear, these people were not afiliated with city hall or other public institutions in any way.

If you drove away, no biggie. If you parked, they would do a big show of moving around the car and telling you when you were too close to the curb, when you should start turning the wheel etc.

Once you were done, they would walk up to you and heavily imply they should be paid for the service they provided ("discovering" the parking space for you and helping you park). You could safely ignore them and they might cuss at you but that was about it.

My girlfriend used to lovingly call them Parking Consultants.

These GH stories have a very similar energy, with middlemen forcefully putting themselves in front of you when you follow a discovery path _that would naturally lead you to the restaurant you were looking for_ (e.g. by showing up higher than the restaurant you're tying to order from in the Google search).

>How can we repair a system that's been systematically corrupted over several years?

Slowly, over several years or quickly with high body count and/or slim odds of lasting success depending on the nature of the proposed changes.

History is littered with attempts to move fast and break things but lasting change takes time because people's attitudes have to change. At the end of the day even unpopular dictators require some amount of consent of the governed in order to rule. You can try to play politics and then use the power gained to push whatever it faster with propaganda, indoctrination, legislation (which is somewhere between an appeal to authority and coercion when used in this manner) but if you push faster than the population actually wants they might push back.
It is possible to hire bodyguards who aren't ex-cops with stained records.

(I don't know the truth about the situation, but if the facts are correct, that is morally troubling.)

> where the amount of police killed per year on duty(even disregarding accidents) is more akin to a third world country than anything going on in the EU.

Police officers in the US face 12.9 fatalities per 100,000 workers. In comparison, construction workers see 14.3, agricultural workers see 17.7, farmers and ranchers around 24 and truck drivers 26.9.

Being an officer is not even close to the top most dangerous jobs in the US. Saying it's on the level of a 'third-world country' is objectively wrong.

If the president wants to express violent/hateful/racist speech, it is even more important the public see it, so that they can judge it and vote accordingly.

I would rather know if the president is a bigot, and their latest misguided thoughts, than not know. I want others to be able to see and judge the behavior as well. Therefore I think the public interest is to provide a free and unmoderated platform.

The solution to a president you dont like is voting them out of office, not gagging them so they appear less offensive. If you dont personally want to see the content > unfollow

I'm not even in the tech industry: jerk yourself off somewhere else.

because Apple will protect your cherished revenue stream

I'm a big fan of free software, and I dislike Apple. You can see this with my post history, it's no secret. Just the other day I got hounded on for calling proprietary software morally wrong. My code's floating around with free licenses all over the Internet. And I love it!

while you go on about how incredibly unethical it all is

Apple's unethical, Google's unethical, but you can release ethical applications on Apple devices (jailbroken app stores) and on Android devices (F-Droid).

Calling people "trying to preserve their livelihood" "incredibly unethical" is the most entitled, self-serving, upper-class-bubbled nonsense I've ever seen in my life.

I grew up in poverty, which is directly where my view is rooted.

Pretending that gutting people's ability to be writers is a net social good

Pretending that gutting access to books for people who can't afford them is a "net social good" is self-serving, entitled, upper-class nonsense.

is such flagrant champagne socialist nonsense

Not a socialist over here (not so fond of capitalism, either), but nice try. If you actually believe in the capitalist nonsense you're circlejerking so hard you wouldn't be against the market providing an alternative.

Disrupting the chain of royalties that allows authors to survive is probably not the most effective way of dealing with it, insofar as your argument boils down to "things authors create are too darn valuable."

The National Emergency Library doesn't include anything published in the last five years, has DRM, so on. It does minimal harm to the profits of authors, and I've already linked a post about the study the European Union funded that showed that actual piracy improves book sales, so...

You want actual change, push for systemic change. Don't act like it's somehow moral to deny a buoy to someone who's drowning, or deny water to someone who's dying of thirst.
> SoHo was looted two days in a row. Where were the NYPD?

Local news reporting tries to explain what's going on: https://www.youtube.com/watch?v=SJGT06zIUiY&t=2m01s

"What you've been seeing is basically a cat and mouse game all night. The police have been here with a huge show of force, but they can't stop people, because they don't know that they've necessarily been looting. And so they're waiting for somebody to do something, police move onto the next block, and then someone does something."

I don't know one way or another whether this is the whole truth, but it appears to play a significant role according to the reporter.
I wish we had more opportunities to learn about and highlight the kind of tech that could change or strongly affect this sort of narrative.

Tech isn't always the answer, but here we are on HN reading about a frustrating issue, a bunch of spinning wheels in a sense, and we're good at tech as a group.

I don't even know what it would look like, but currently the typical HN community response to this stuff is hyper-perceptive. From "here we go" to "here's what the article says". This alone is far too limited (we're not just here with our popcorn; we want to _do_) and it creates a pattern that can eventually shut out such news because no traction can be gained--what's the point.

IMO we can build communications environments and frameworks that empower ourselves and others to take creative action, even of the sociopolitical type. And if we can't build 'em, we can share and promote the news.

(Some of you are already doing this--thank you, please keep sharing your work)

It certainly sounds like we need to fire that guy before he “teaches” any more police.
The point is that the two are coupled. It is not clear why 0 false negatives is the aim. In almost all hard problems, you cannot have 0 false positives and 0 false negatives.

Normally, getting to 0 false negatives requires a large number of false positives. E.g. if I wanted a 0 false negative pregnancy test, the only feasible way would be to tell some very large proportion (maybe all) test takers they are pregnant.

If it requires 20 innocent people to be killed in order to achieve say a goal of 1 police officer failing to identify a threat, who says that is the right balance?

You want to take emotions out of it, I say the life officer of a police officer is no more important than an innocent person, and given a police officer has a) control of which situations they enter and b) presumably accepts some level of risk from the job the choose and c)
Killings by police are an externality that the police system is not incentivised to fix in a meaningful way , they should bear the burden of systemic risk from those interactions. Accepting no less than 1 innocent death for 1 police death seems like the rational baseline, and I think there are compelling points to suggest it should be less than one innocent death to police death.

Quite many people are unhappy with their newer Macbook experiences! Sad to see the quality drop in Apple products.

I'll add mine to the list:

My 2012 MacBook Air has been my favourite laptop I used it for five years and my parents two after that. One of the best 700 hundred euros (student discount) I've spent.
Then for my work I got previously used ~2014 MBP it worked well. Solid "Apple quality". Then I got an "upgrade" (i think it was 2018 MBP) and it was the most unpleasant experience I have yet to have with computers. Luckily I didn't have to pay for it, but still - so many problems that are unacceptable for any laptop. It really got me out of the Apple fanboy train.

- Keyboard didn't work if the computer got too hot (which it did)
- Some buttons didn't properly as dust or some particles got under them
- Same problems with the trackpad than the article writer
- Don't even get me started with the touchbar (why?!)
- Battery life disappointed as I was expecting it to atleast compare with the 2020 Air's (of course my expectations might have been the problem here)
- If external monitors were hooked up and you woke up the laptop there as 25% that it froze completely and you had to reboot

The laptop got sent to maintenance - they dusted the keyboard but other problems persisted. After one year of that pain I went back to studying and bought used Thinkpad X220 and installed Arch. That is now my favourite computer!

Last month I bought XPS 13 for programming since x220's CPU doesn't support virtualization. It runs manjaro and is like 2014 MBP was - does the job really well. After finally going full into Linux world I wonder if I'll ever come back.
Orwell, writing about the Spanish civil war, gives the release of arms stockpiles to trade union militias as a key factor in the early fighting against Franco. That war saw a combination of foreign intervention, plus soldiers and police choosing either side, but militias still played a crucial role.

It's not clear whether arms stockpiles would have the same impact on a modern war, but they might.
I enjoyed the article, but am maybe too dense to understand the repercussions. My understanding of the summary is that a goal is to be able to develop these graphs and then convert them back to ruby so that developers who know ruby can see how the compiler is optimizing. My honest question is, why does this matter? If the developers then start writing code more in line with what a compiler would do, then it seems compilation would be faster - is it significant, and is this a reason why? What else could it be? Thanks for the article and any thoughts!

I haven't read the article, but #4 is the interesting item on that list. #3 is the Goldilocks option, the one that sounds between-the-extremes like the just-right porridge that Goldilocks ate—but it's not realistic, because "be extremely cautious when interpreting them" exceeds what the human mind is capable of.
At a certain philosophical / high level, I don't like the idea of the 'human-memorable names' .onion feature.

It's politicising software. Open-source software should never have an official, hard-coded opinion about any of the content findable through it.

I've seen the Firefox org increasing do similar things when reading their email newsletter. It even stopped me donating to Firefox.

A core idea of Tor is to not censor. When you give special access to some sites, it feels like the opposite of net neutrality. That is on the censorship spectrum.

I guess it's not too bad if they never block any content at the protocol or software level, but at some point, giving certain content privileged features at the software/protocol level is a two-edged sword. It means you're forced to deny supporting other content.

Indeed, once Tor starts having an official opinion about online content at the browser level, who's to stop people starting to pressure Tor to block certain content, since they're basically starting to be in that realm now? It can be a slippery slope.

I'd prefer at the very least it be toned down to a third party add-on. It's great to make onion sites easier to access, of course. But it should be in a way that doesn't involve political or legal barriers for content creators.

BTW, I highly encourage anyone with a linux box at home just sitting there 24/7 to start an obfs4 bridge relay. It's not that hard, and low on resources. #tor-relays IRC extremely helpful in getting you set up.

I've been running one for about a year and it's provided tens/hundreds of GBs of Tor Internet to people hopefully in Asia, South America, and the Middle East - protesters who really, really need some help in anonymization or gaining access to blocked content.

that's not unreasonable. I saw your post a few minutes after another that claimed there were a billion guns in the US, so I was starting to wonder if this was a common misconception.

I personally don't feel that pervasive civilian gun ownership is incompatible with proportionate policing, but that's certainly a debate that reasonable people can have.
Barr is one of the most dangerous AG's this country has ever had. He believes in extreme executive power. That "secularism" is evil and the downfall of this country. Worst of all imo, is that he believes that the law enforcement of the federal government is there solely to serve the president. Somehow he still calls himself a conservative.
Joining the police is a choice. Being a woman of color is not a choice. Making a blanket statement about those two groups is therefore entirely different.

My blanket statement about police was also framed as a question. I said I have seen very little evidence I was wrong. If you think I am wrong, you could try providing an answer to that question rather than attacking the question itself.
