The nice thing about rings or other methods like racetracks etc is that the particles come around and go through the same accelerator structure multiple times. Secondly, if you want to collide two beams, the advantage of a ring is that each particle has multiple chances of scattering of the other beam, as it "comes around" to the intersection region millions of times.
That being said, linear accelerators are a thing, as they have other advantages.
The best guitar players also do a form of stretch tuning, depending upon the range of the piece that they are playing. Just as on a piano, the high end of the instrument will sound flat if they didn't. This is a limitation of all stringed instruments.
I've been driving in intense blizzards and ice and steep bad roads of Colorado for 20 years now. Still never had an accident or even gone off the road. That's the standard. Anything less and I'm completely uninterested, because it's just bad tech.

When your engineers say the problem is "too hard to solve" you need to hire better engineers, because those engineers are lying to you. Just because everyone is racing towards a technology and some teams are doing it poorly doesn't mean the problems are insurmountable.
I walked to school as a young kid too in the US, but that was decades ago. Things have completely changed so you and I were children.
I don't think you understand Dart's type system. It has “dynamic”, which is equivalent to “any”!

Dart's type system is worse because you can pass in null for any type at any time. This circumvents any sense of type safety your method signatures might suggest. It's no better than Java.
A self driving car won't have a steering wheel, break and accelerator. Because it really doesn't make sense to expect user take control instantly while the algorithm panics.

Basically when people say the term self-driving car, they mean a human brain like entity driving the car. Humans don't exactly panic and expect a person sitting next to them control a car in case they can't handle it. Sure in those situation a human would get into accidents too. But in case of a machine, such an accident is already programmed to happen. Its like fixed. Which is a very different thing. In fact its even wrong to call it an accident if you know a panic will happen. Its more like programmed manslaughter.
It isn't nearly as easy to connect to people outside the workplace. You have to reach out to people to get their personal contact details, and doing this en-masse could be construed as organizing activity by itself. They could even argue you are ex-filtrating confidential information (list of employees).
> It's silly to equate a legal defense with a belief though.

It's actually silly not to. As was said; when there is something at stake their story is something other than what they offer while placating outrage. I can't fathom rationally choosing to believe meaningless pillow talk over the black and white filings of Google's representation in a court.

>That sapiens mostly preferred 'Abrahamic religion' to others is then a consequence to this starting point.

Sapiens didn't mostly prefer Abrahamic religion. Judaism didn't proselytize as far as I'm aware, and Christianity and Islam converted many cultures and people by force (although not exclusively.)

And you're not considering the widespread preference for Buddhist and animist religions, which over time likely equal if not surpass the Abrahamic faiths... although to be fair those also sometimes were spread by force as well.
Debit cards in almost all cases have less protections that are clearly stated.
This can be easily illustrated using this example [1], which uses both the Boehm GC (v8.0.2) and jemalloc (v5.0.1), directly installed via Homebrew, as well as the system malloc on macOS to implement the binary trees benchmark from the benchmark game.

The benchmark keeps a large live set and allocates aggressively, making it an unattractive scenario for many GCs.

The Boehm GC is being run with the following four distinct configurations:

- Four marker threads in parallel, trading CPU time for wall clock time and lower pause times.

- Single-threaded marking.

- GC disabled, all memory is freed explicitly.

- Incremental collection (using virtual memory).

The results, run on a Macbook Pro with a six core 2.6 GHz Core i7:

$ make benchmark DEPTH=21
# jemalloc explicit malloc()/free()
/usr/bin/time ./btree-jemalloc 21 >/dev/null
17.53 real 17.40 user 0.11 sys
# Boehm GC with four parallel marker threads
GC_MARKERS=4 /usr/bin/time ./btree-gc 21 >/dev/null
8.50 real 10.87 user 0.09 sys
# Boehm GC with single-threaded marking
GC_MARKERS=1 /usr/bin/time ./btree-gc 21 >/dev/null
10.40 real 10.33 user 0.05 sys
# Boehm GC with explicit deallocation
GC_MARKERS=1 /usr/bin/time ./btree-gc-free 21 >/dev/null
11.75 real 11.70 user 0.04 sys
# Boehm GC with incremental collection (single-threaded)
/usr/bin/time ./btree-gc-inc 21 >/dev/null
18.39 real 16.40 user 5.11 sys
# System malloc()/free()
/usr/bin/time ./btree-sysmalloc 21 >/dev/null
64.43 real 63.69 user 0.71 sys

Obviously, one should not read too much into this, as this is a very specific scenario with its own very specific allocation behavior that will not match other use cases. And one can speed up this specific example easily with a specialized allocator (as all allocations have the same size and predictable lifetime). Plus, different GCs make different tradeoffs, and so do general purpose manual allocators.

But for throughput at least, the worries about GC overhead tend to be exaggerated.

In practice, any language with proper value types will also spend only a fairly small fraction on allocation and garbage collection, so overhead becomes less of a problem.

>Non-tenure track academic teaching positions that pay "horribly"... I can already imagine the kind of talent they attract.

Honestly, as a former CC student, non-TT professors/lectures at the junior level were some amazing teachers. While they may only have a masters in their field, most of them are taking these jobs out of enjoyment as secondary income or after retirement.

Examples: One psych prof is a clinical child psychologist, teaches PT, highest evals in the dept.

Other psych prof, retired psychologist, head of CHARGE research, drove 45 minutes to teach PT

Social work prof, 20+ year professional, teaches PT, was a complete savior to her students.

Eng prof, trans, former Navy, journalist, taught PT.

Chem prof, retired, works at a local grocery store stocking fruit PT, lectures PT

I'm a googler, going anonymous for soon-to-be obvious reasons.

While I think this headline is overblown, I think the change would be for the better. For the past couple of years working at Google has been like what I'd imagine it's to work for the Trump administration: constant scandals, people around you being outraged, constant diversion of internal attention to issues unrelated to the core business etc.

Nominally the internal culture is all for open communication and being yourself. However, it's far easier to express an opinion that signals your 'good' and 'acceptable' values by eg. demanding Google shuts down anything that's even remotely suspicious. This leads to the loudest voices being the most extreme ones and makes you feel like you're alone with your opinion if you happen to favor nuanced debate over knee jerk reactions. For example, I think Dragonfly is a good idea and something we should pursue - but honestly, I'm only comfortable expressing that opinion to a select few coworkers in a private setting.

This brings me to my point of why I think more company control over worker organization might be good. I take pride in my work ethic. My dad raised me to respect the work I do. And every time a new scandal comes along and the internal company focus gets diverted to an issue on which only a small part of the company feels comfortable expressing their opinions of, my attention gets diverted and my work suffers. As does the company as a whole. As a stock owner, having an internal company culture less focused on outrage would be a great improvement.

I've never quite believed this argument. It's worked in a lot of circumstances, I agree, but it requires the dimensionless constants to be of order 1. This is usually a reasonable assumption, but it's known to be false in gravity! The cosmological constant ought to be the leading order term in the EH action, but it's too small by ~100 orders of magnitude.
Interesting side note, when I did a 4-day water fast, I noticed around day 2 that my morning breath was virtually gone.

That cost too is highly inflated. My wife has a crazy bad eyes/strong prescription and she was able to get glasses including frames for under $70 from Zenni.

I agree you need to keep expectations realistic, but ... it's not like humans have access to some special snow oracle or rain oracle that we use to drive, and it seems unnecessarily pessimistic to bet on "we can never get a machine to recognize a rainy environment like humans can".

I read somewhere that a mix of 50% olive oil and 50% butter very closely approximates the lipid profile of human fat. If saturated fat is bad for you, why does the body choose to store "bad" fats? Wouldn't evolution have weeded out saturated fat storage since it's "bad" for your cardiovascular system?

While it is not completely impossible, if political ramifications were the prime drivers, meat, dairy and grain would have a lot more space and would have suffered when comparing to previous version of the guide.

The guide as likely little effect outside the country, its effect is more on small institutional kitchens (daycares, schools, clinics etc.), its content is unlikely to affect international sales. Its political effect is more likely to be felt internally, through perception of people in the affected industries rather than the effect the guide may have on their sales.

Some of the not so favoured are powerful industries what occupy a lot of land across several provinces (wheat), have suffered recently and are getting more politically active (dairy) or are in areas where the party currently in power needs to keep its support for the next election (meat).
>Aafia Ahmad, a sophomore computer science major at U.T. Austin, had hoped to take an elective course in computer security this semester. But when she tried to sign up during early registration in November, the course was already full.

I know this doesn't refute the point the article is trying to make, but it doesn't seem that unreasonable to me that an underclassman might not get into a highly sought after elective. A lot of the "fun" electives when I was in school were little passion projects taught by one professor for one or two small sections a semester (or maybe only one semester per year), and while I agree it sucks that not everyone can take the classes, I wouldn't want them to die out because of complaints along the lines of "if you can't accommodate everyone, don't offer the course". Not that the article is saying that should be the case, I just worry that too many complaints about this kind of thing just puts pressure on the good professors who put enough effort into a class that a bunch of people want to take it.
The answer is that being a human with moral and ethical obligations to the rest of humanity should take precedence over being a corporate leader. If you don't sell censorship and weapons tech or cut backroom deals to silence victims of sexual harassment, there's no need to try to stop your employees from talking about it.
> It appears that there is a conflict of vision within Google.

Perhaps, but when then chips are down and Google is obliged to file their position on pain of perjury it is clear which 'vision' is real and which is window dressing.
For a moment I thought that Native Instruments actually built it and got into that business.
As a liberal, I hate to admit, but you're totally correct here.

For one thing, military bases are not at all representative of regular USA; they're operated by the DOD and rules there are entirely different than in civilian places, and are largely up to the discretion of the base commander, not the local police department and courts.

Also, the way things are in small towns ("red") is completely different than in both urban areas and also in rich suburban areas. Where I expect people to call the cops is in the rich suburban areas, which aren't exactly what I'd call "bright blue", they're really their own weird version of purple (lots of Republican voters in those places, but they're not like the Republicans on military bases or in small town USA).
Man, I didn't think that at all but now I wish it was! Would love to read some in depth articles about these kinds of social clubs and the societies they create
A lion has tougher skin than a human. But the primary difference is knowledge. We as humans know that some small tiny spiders are warrant no amount of fear but some, like the brown recluse, can absolutely mess your day up. A small brown spider is a small brown spider to a lion. On a more higher level, we are aware of our mortality, and this colors our entire experience of almost everything in life, from the biggest things to the littlest things like spiders, which is why all the world's faiths all have something to say about death. I am not sure the lion sits and contemplates his mortality.

Not really. It’s a good question to ask but the answer is rather simple: R1 institutions stay afloat because of research grants; they need researchers to secure that grant $$.
It seems, from the outside, that Google has quickly pivoted over the past 5? years from an innovative tech company to an entrenched, political operation trying to preserve status quos and revenue streams.

Is that naive impression off base or is the kernel of truth there?
I understand why you think that, but isn't it possible for other people to be compassionate? I think of all of the people that flock to cities to volunteer after a natural disaster. The most compassionate will be able to use their money to put it towards the things they care about. Additionally, if this was implemented at the local level, the excess tax pool, would be able to be accessed by all locals to directly help their area.
> I find it curious that we are going to hold autonomous vehicles to a perhaps impossibly high standard while we also hold people to barely any standards at all.

This is all US-centric obviously, but my 2c: We can blame individuals for bad behavior, it's harder for us to reason about complex systems breaking and that scares us.

When an accident happens currently, we immediately rush to judgement: You're a bad driver, you were going too fast, there's order in the universe and you made a conscious choice to disrupt that. We'll really reach sometimes too (I've heard this in real life): You had a stroke and lost control of your car? The crash is still your fault, you should've lived a healthier lifestyle. Or it's your spouse's fault, they should've noticed you were acting funny and not let you drive the car.

When people screw up, it's almost always someone's fault even if we have to really reach for it. We rarely consider the system that led to the failure and absolve the individual. When computers screw up, it's unclear who to blame and it's much scarier as a result, so we hold computers to a much higher standard.

the competition is often between people with phds. i am not 100% sure that a university teacher needs to have a phd, but it seems that even keeping that requirement, the present system is pathological. most people with phds do not make the cut for researcher, which leads to the university being short on teachers.
Can confirm that the police fraud report helps grease the gears (in the UK, this is done through Action Fraud).

The bank went from "we won't help you" to "oh, we'll fix that" about as soon as I told them I had a crime reference number...

I guess this has something to do with the penalties for making a false police report being much higher (in criminal law terms) than lying to a bank.

Ask HN: My co-founders are screwing me. What can I do?
(throwaway to keep anonymous)

I'm co-founder and minority share holder of a small company. No investors. Company is not doing so great in last few years. Bad product decisions. Feature bloat. Bad sales. and so on. Customers are leaving and business is going down. Some customers will probably stay long, so there is still money.

My role is quite critical. But I kinda automated my job and my stuff is working really well. So even if I leave, things will stay ok for a some time. And also bringing someone to take over would probably be ok.

Our agreement basically to get same salary. But now they cut my salary big time. And theirs not.

I can sue and probably win. But by the time I win (takes long), maybe there would be no money to win.

Technically I can probably do something to pressure, but it might be not legal (and not moral).

What to do ? or not do ? Sorry for bad language. Not a native.
The system is completely different in Scotland from the rest of the UK - undergraduate degrees are usually 4 years here rather than 3 years in rest of the UK.

This is largely based on the fact that admittance is done mainly done on what people do in 5th year of high school rather than 6th year A-levels.

At this point, I use Docker for almost every project that I work on, and one of the reasons is that Docker allows me to create a separate environment for each project. I don't need to learn multiple version managers, and it works equally well for non-language tools, like Postgres and Redis.
Another good reason to use a fintech bank account such as Monzo [1] or a credit card such as Tandem [2] or a virtual card that can forward transactions onto any other card such as Curve [3].

All of these services can give you a push notification every time a transaction is made on your account so that you are immediately made aware and are able to cancel them. You can block the card from within the app immediately.

I'd also like to point out that the entire state of Utah felt it necessary to pass a law making "free range parenting" (letting your kids run around outside unattended) legal, because they had so many problems with people calling the police.

Remember, any time the police are called, even if it's stupid, they have to show up and investigate, and when there's no parents around, that means they have to find them, and at the minimum you have a giant hassle on your hands.

Even in the incident you cite, the CPS did act badly, and that was just in one place. Why did they ever get to the point where they acted like that in the first place? It would have been unthinkable in other developed nations.

And in your own link, the last line is:
"The encounters between the Meitivs and the government have led to an intense debate among parents and educators.["

Why is there an "intense debate" about this? Obviously it's a big, big issue in the US, or else there wouldn't be any "intense debate" about it.
