Faster trading allows market makers to operate with smaller capital investments. This lowers the barrier to entry in the market making business, creating more competition. More competition reduces the costs of trading. (And not just in theory. Market making used to be exclusively the domain of a few big players. It's not anymore.) Reduced cost of trading matters to almost everyone who's involved in the markets. Passive index funds, for example, have to trade to reinvest profits and to rebalance their composition. That's why Vanguard -- the most evangelical of the passive fund managers -- firmly defends HFT.

You may ask, well, why do we need market makers at all? Well, you don't have to use them. You have other options for trading. Call up your broker and ask. What you'll discover is that these other options have far larger transaction costs.

A lot of the complaints about HFT I've seen on Hacker News seem to think that no one should get paid for market making. I don't think that's possible. (And if it is, I'd love to know how.) Transaction costs are an inescapable part of trading; ultimately, you're faced with the choice between tilting your hand to other traders or paying some intermediary to take on risk for you. Generally, it costs less to choose the second option.

>> The majority of prisons are still state owned and run.

Do you also have privatisation happening by the back-door?

i.e. how many private services do the public prisons use? You get some weird situations where public institutions use staff from contractors, rent buildings and buy in all their services.

Docker in the Cloud: Introduction to AWS Container Service
A common refrain you hear from law enforcement is "ignorance of the law is no protection from breaking it."

But what if it was?

As Harvey Silverglate details in his book, "3 Felonies a Day,[1]" it is absurdly easy to accidentally commit a federal crime and serve prison time. The idea behind vindictive punishment is to make it so bad that you won't commit a crime, but if people aren't aware of the liabilities, how can people truly know their risk? Often intent has to be proven, but if it's in the interest of the prosecutor and their career to get a conviction, they'll get a conviction.

I think to reduce the "arrest/convict, ask questions later" approach is to give every officer and prosecutor a publicly available scorecard that shows their record of rightful arrests and convictions versus wrongful ones, as well as excessive punishment sought and applied in wrongful cases.

There is a scene at the end of the hilarious murder trial film, My Cousin Vinny, when the defense's expert witness completely shatters the prosecution's case, and the prosecutor immediately moves to dismiss all charges. I wonder if that would happen today?

> exercise is not they key to weight loss, proper eating is.

Anecdote here, but I've found that for me the key to weight loss has been exercise-first. I decided that I'd never be very good at reducing my dietary input (I really enjoy food) so I focused instead on increasing my energy output by incorporating progressively more physical activity into my lifestyle.

Over the past few years I have steadily and gradually ramped up my activity through walking, running, cycling, body-weight exercises, plyometrics, stand-up desk, and so on, and I've been progressively losing weight and feeling better physically, mentally and emotionally. As a result, other complementary aspects of health - sleeping, eating - have also tended to fall into healthier patterns in a positive feedback loop.

It's hard to believe that exercise isn't the key to weight loss when I burn 2,000 calories on my Saturday morning run.
I don't believe the prison work programs are forced at all, I think they have a choice to do it. Instead it's a chance for them to get work experience/vocation education that they might not have received.

Yes if you do it every day. The reality is that it's normally just as easy to eat -50 cal a day so it balances out for most people.

Also I think it would be more normal to eat +/- 50 cal from maintenance each day then occasionally go way over, gaining weight that way.
One reason for this are mandatory minimum sentences. And in that case, it is the politicians who made the sentencing, in a way.

I agree that knowing basics of Vim is of great help and adds value to a programmer's skill set.

I don't agree that it should be the only thing one uses for all development/writing tasks.

Yes, vim is ubiquitous. However, no one uses vim without high levels of customization. So i think there is a bigger dependency issue here.

Also, I've seen millennials struggling to cope with vim - it's like handing a cassette to a person who's grown up with an iPod.

That is exactly the control mechanism that was used by a number of Arab countries, including Saudi Arabia, to prevent the Arab Spring revolutions from happening within their borders. They handed out billions of cash to the populace.

"...the Saudi state began spending $130 billion to pump up civil servant salaries (paying two extra months’ salaries)"

"In Kuwait, at around the same time, the state increased civil servant salaries by 115 percent at a cost of more than $1 billion, and at an additional cost of $5 billion, gave a cash handout of Kuwaiti Dinar (KD) 1000 to its citizens and promised free distribution of foodstuffs for fourteen months"

Actually a lot of judges were very opposed to mandatory sentencing because it removes a lot of their power.
I want to point out that the console uses a (quite appealing [1]) fixed palette of 16 colors for all of its graphics. I think having a fixed palette is a great idea. I can see it helping would-be game developers overcome their initial art style analysis paralysis and helping ensure that the games have a recognizable "PICO-8" look.

The problems are:

- The hardware you are emulating is usually undocumented

- For recent systems, you must use a JIT for CPU emulation or it will be too slow

- For pretty much anything with 3D, you need to use GPU acceleration or it will be too slow (and the host and emulated GPUs might work very differently)

- Users want to run 3D games at arbitrary resolutions higher than the ones intended for the emulated targets, so you need to add trickery to handle that (like transparently resizing framebuffer-sized internal textures and so on)

- For recent systems, you may need to emulate a memory access with a single memory access, which means you need to setup the host virtual space to be the same as the emulated system, which requires lots of tricks to handle MMIO regions, memory mapped in multiple places, and finding a place to put the emulator code

- Sometimes you need to emulate one or more software APIs instead of the hardware, because emulating the hardware would be too hard or too slow or not allow to replace functionality (this is called "HLE" - high level emulation)

- You need to map keyboard+mouse and optional 360 controller to whatever input system the emulated target uses, as well as supporting plugging in the actual emulated controllers with some kind of adapter

- There may be a copyrighted BIOS or OS that you need to reimplement or support extracting from the machine
Often times judges have their hands tied. Many minimum sentencing laws were passed in the late '80's & throughout the '90's in response to the crime waves of the era. Judges simply can't give lower sentences in many instances even if they want to. In my opinion, this is a significant contributing factor.
Pretty much. The bottom of the 1% is the elite of people who still actually work for a living, such as lawyers, dentists, and doctors.
You're right, there are certainly many mental factors that contribute to weight gain, such as hunger, willpower etc. that vary from person to person. However, as far as actual physical weight gain (controlling for height and muscle mass), the dominating factor is calories in vs. calories out.

For people like you who are tall and skinny and it seems impossible to gain weight, you are either not eating as much as you think you are consistently (i.e. not correctly tracking your calorie intake) or you are grossly underestimating how many calories obese people consume on a daily basis.

Just eating at McDonalds 1-2 times a day doesn't mean anything if you are just getting a burger, but if you get three burgers, a large fry and large coke on a daily basis, that is going to make a difference.

Along with mental factors, poor dietary upbringing, as well as horrible (and consistently changing) nutrition advice are strong contributors to problems with weight gain.

>An odd thing to say about a slate article, but I think they're overthinking it.

I've seen this same trope going around recently that drug law reform won't help us control the prison population, usually as an excuse not to reform drug laws. If you get caught with drugs, you may well be breaking other laws that allow police or D.A.'s to charge you as a violent or higher level offender. Caught with drugs and a gun? Your gun possession may have been legal in absence of the drugs but now you may be on the hook for a/another felony. Did you "resist arrest"? They love this stuff because they think it makes them look more effective.

Real engineers are like true Scotsmen, because you can never have enough process.

In this case, of course tests really do prove the absence of bugs rather than just (not) proving their presence.

I really don't like the whole "unit tests lets you not worry about breaking things" view. That's not confidence, it's overconfidence. And it doesn't even mostly work for things where "correct" is more fuzzy than "eventually produces this exact output".

You'd be surprised what constitutes a felony. In some states a theft or destruction of an item valued at over $100 is a felony. In fact the crux of this article is that the prison population has risen so dramatically due to the decision by prosecutors to file dramatically more felony charges than they they had previously filed:

"What appears to happen during this time—the years I look at are 1994 to 2008, just based on the data that’s available—is that the probability that a district attorney files a felony charge against an arrestee goes from about 1 in 3, to 2 in 3. So over the course of the ’90s and 2000s, district attorneys just got much more aggressive in how they filed charges. Defendants who they would not have filed felony charges against before, they now are charging with felonies. I can’t tell you why they’re doing that. No one’s really got an answer to that yet. But it does seem that the number of felony cases filed shoots up very strongly, even as the number of arrests goes down."
It would be terrible if photogenic, attractive and likeable people went to jail for the same amount of time as an ugly asshole who isn't part of our tribe. If that happened, we'd have a relatable human face going to jail.
My favorite explanation I found on the issue is on "The Hacker's Diet" (free ebook).

https://www.fourmilab.ch/hackdiet/e4/

The author's theory is that the issue is not on of metabolism, but that people overeating do not have a good "I'm full" mechanism.

Most people like you that "can eat all they want and not gain weight" in reality... don't. They balance out their intake naturally, if not in the scope of a meal, over a day or so.

For example the concept of leaving unfinished food on the plate it completely alien to me (or not going for seconds if available), while most normal people just stop when they feel they are ok.

In my very personal and anecdotal experience every time I started dieting counting calories and exercising I have always lost weight, consistently, while when I stopped I gained weight back (again, consistently and predictably).

Most other diets that have a scientific basis should be efficient as well, since what they all have in common is to enforce some sort of control on your intake.

Either way I agree that it's about genetics and willpower but, not having the possibility to change genetics, the mechanism to counter it exists and it's not a mystery, it's really a psychological issue, IMHO.

Relevant recent quote from someone at the UN:

> "Unfortunately only when the poor enter the halls of the rich, do the rich notice that the poor exist."

http://www.reuters.com/article/2015/09/27/us-un-assembly-ref...

Inequality is a problem for the rich, too, and not just because the poor will eventually revolt on them and take their stuff by force or murder them violently, but also because when most money is concentrated in the hands of only a few, the "economy" becomes weaker and less dynamic, as people can't afford to buy all sorts of stuff anymore (from the rich people's companies). The lesson here is not to postpone solving the inequality problem until the poor are already at their doors or causing riots in the streets.

Fast Algorithms for Exact String Matching
Finally. I was unfortunately victim to this (not in the US, but in Canada) where objectively, it should have been dropped, but the prosecutor wanted to make an example of me. The case was unbelievably flimsy, but you have no idea the pressure you're under when you're facing opponents who have financial and social incentives to punish you. The morning of my trial (I refused to accept anything before then), the prosecutor was losing her shit because she could lose, screaming and yelling at me. I literally laughed in her face, then accepted the least possible thing that resulted in no conviction or record without a trial. The witnesses had financial incentives to lie and I did not have the resources to go through an appeal.

Things I heard throughout this ordeal:

1. If you were white, this never would have happened.
2. I cannot believe how much $witness is lying, yet you can't prove it.

Since this problem, I've seen the same prosecutor try and catch other people in the same bullshit law to the point where it has been in the news. I've countered with my own silent battle, getting politicians to talk to me and I can say that this has directly resulted in some changes, which I'm happy about. One of them told actually told me that he wishes I would have won so that he could use me as an example. Can you believe it?

I gotta tell you, it's frustrating as anything I have ever experienced in my life. But living well is the best revenge and I've got a great life.

> Some people won't need your plan because they stay at low weight no matter what they eat.

This is just not true. I find that the people who say that actually eat a lot less calorie wise than they think. Eat 4500 calories per day for 2 years and see if you stay skinny. McDonalds 2 times a day is more like 2000 calories at the very high end. It takes time to eat 4500 cals per day, most skinny people can't do it at all but it's easy for fat people. Eating only unhealthy food every day doesn't really say anything about energy in vs energy out
I will caveat this and say that I am speaking from an entrepreneur's perspective, and OP obviously has more experience investing than I do, but I am skeptical of taking this line of thinking too far.

There is a problem with this model—and I am not saying it won't work—that VC firms get the best deals by having high deal flow and have a reputation for working supporting entrepreneurs (or in some cases firing the CEO and making the company extremely successful). If you treat the VC market like the stock market, with quant trading firms, you will: (1) miss deals because oftentimes once a company has any visibility it is too late to get in their investment pipeline, (2) make bad decisions because it is hard to extrapolate from very little data.

To your point about no management fees, unless you are independently wealthy, how do you cover costs? I ask not as a rhetorical device, because it is not possible to propose such a thing without a plan, I am just interested to know how you think about it.
