Boston | Full-time | Onsite

We're hiring Haskell & Elm engineers for a Boston-based distributed systems startup (still in stealth mode) focused on automated data engineering. Must be willing to relocate to Boston.

Knowledge of Machine Learning and experience with distributed systems a plus for Haskell position. Knowledge of basic information design a plus for Elm position (but definitely not required!).

Reach out to me directly via brendan@hyperplane.vc if interested.

PS: Even if you're not, we'd love to grab coffee or drinks with fellow Haskell engineers in the area.

> "Making email and PGP easier to use is not only a UX issue."

Yes, but UX is still the biggest issue. By all means develop next gen crypto tech: but first, make what we have now usable by people who aren't Unix people.

I would pay money for binaries of an Open Source GnuPG for OS X which wasn't awful to use.

Out of these two, the plea bargaining system always seemed the most corrupt to me. It's also widespread (in some form^) and predates privatization.

I say some form, because confessions forced with threats of far worse punishment are a long unbroken tradition. It used to be more common for them to happen after sentencing, say during your punishment.

The modern form usually revolves around an enormous range of potential punishments. 6 months probation if you confess/bargain, 6 ears in jail otherwise. It's especially malicious because it's all happening between lawyers, without judicial involvement. Well paid lawyers are important in courts too, but at least there is a neutral judge in the room.

It's not unique to the US.

If "high tax" countries have a genuine problem with this then they should reduce their corporate tax. Don't blame the solution, blame the problem.

If corporate tax is 30-35%, people are going to try and optimise as much as humanly possible. If corporate tax is between 10 and 20%, it becomes a lot less of an issue.

Except it never answered why the DA's are sending more people to prison. That sort of begs the question, right? The best conclusion the author came up with was:

> Maybe it’s that next election they’re looking at, that they remain tough on crime because they want to become attorney general or governor. There’s no clear data on this.

which is a super weak answer. As jordigh said above, it's because prisons are now largely run for profit. Most people who were already aware of the large prison population already knew that for-profit prisons was the reason this phenomenon occurred. Honestly, this article sounds like a propaganda piece to serve as a red herring for the for-profit prison industry to keep chugging along.

Any government agency meets this description, though. Your sense of smell is accurate -- it's where fraud does occur in reality. But the more serious fraud on the public comes when prison owners are incentivized to buy less food and sell the labor of their prisoners.

Sorry, haven't RTFA, but what I know is that when people get heavier, the babies they get are biased to more weight. These kids, now adults, have a body that is trained or prepared for more weight, and it won't give up that easily.

I'm 5 kg overweight, and should lose another 10 kg to get the ideal weight. My goal is not to gain any weight, and I've kept it stable for about 10 years. I know when I overeat, and I feel really bad when I gain another kg. If that happens, it takes a week or so to lose it again.

In Texas, we had a prison system director named Andy Collins who involved himself and the whole prison system in a huge scandal(s) about 20 years ago, and the stink from that still hasn't gone away. It was super embarrassing. Collins signed contracts to purchase some soybean product that was supposed to resemble food from an ex-convict (from Canada, not TDCJ). He didn't use the required bid process, and was receiving kickbacks for the stuff. They bought so much of it that it sat in warehouses and rotted. The inmates just wouldn't eat it. (source: I was a TDCJ guard at the time). The current directors seem content with minor scandals, and are presently leaving the wide-scale graft to someone else. TDCJ has been pretty territorial in protecting their control over staffing, and the citizens of the state were happy to fund enough concrete and bars to prevent the state needing to use those kind of creative tricks in order to get more beds. The biggest scandal with prison privatization in Texas, as far as I am aware was the problem(s) I mentioned before with the Texas Youth Commission. That's not an argument for privatization though, our private prisons still suck; we just don't do much of it here. We're apparently very proud of having one of the largest prison systems in the world, and I think our public prison officials tend to see private prisons as a threat (at least until they retire and consult for them).

>You get some weird situations where public institutions use staff from contractors, rent buildings and buy in all their services.

Yeah, IIRC TYC had all of that, and while it was talked about, nothing was really done until the sex-scandal broke.

> That "1 lb / 3500 calories" figure you quoted isn't an absolute law, but more like a rule of thumb.

And it's not even a very useful rule of thumb. Research suggests [1] that because of how the energy dynamics work in practice (i.e. a sack of ideally functioning fat cells is a pretty unrealistic model for human metabolism), most people need an estimated deficit of much more than 3,500 calories to actually burn a pound of fat.

HOW TO:Sketch your next great email template
Just thinking aloud here, but if your user name is the email address, you could actually store a hash of the user name, use that to look up the account and verify the login, then keep a map from the hash to the user-entered name in an in-memory database. This way the user name (email address) never gets stored.

This would also work when someone has forgotten their password, as long as they don't forget the email address they used to sign up. (This is actually the only reason why the user name has to be the same as the email address.)

You can't send regular information emails with this, though.
This is really interesting! There seems to be some additional technical information here:

https://boards.openpandora.org/topic/18485-free-lossless-ima...

- for interlacing it uses a generalization of PNG's Adam7; unlike PNG, the geometry of the 2D interlacing is exploited heavily to get better pixel estimation, which means the overhead of interlacing is small (vs simple scanline encoding, which has the benefit of locality so usually compresses better)

- the colorspace is a lossless simplified variant of YIQ, alpha and Y channel are encoded first, chroma channels later

- the real innovation is in the way the contexts are defined for the arithmetic coding: during encoding, a decision tree is constructed (a description of which is encoded in the compressed stream) which is a way to dynamically adapt the CABAC contexts to the specific encoded image. We have called this method "MANIAC", which is a backronym for "Meta-Adaptive Near-zero Integer Arithmetic Coding".
It's easy to find self-described Christians who are extremely right-wing and favor harsh sentences for "lawbreakers" because they see themselves as the good people who will never break a law, and therefore never experience or otherwise have to think about proportionality.

If they are at all studied in classic literature and world history, it should at least be at the back of their mind, because it's been a known effect since at least the Romans. Where do you think the phrase "bread and circuses" comes from?
Perhaps the MANIAC/CABAC decoding or encoding is computationally more intensive compared to the others? Concerning lack of support, just like with the BPG decoder you could generate the Javascript through Emscripten so any javaszcript enabled browser can view them. Personally an even more efficient lossy image compressor would be great (getting my avatar down to 1K and still sharp). When using diagrams or text the mozjpeg artifact eraser is adequate.
Migration State and Welfare State
Like so many things, there is no single correct answer.

For myself, if I focus on diet and not worry about exercise I find that I have to eat very little if I want to lose more than a few pounds. So little that I'm miserable all the time. Forever. On the flip side, if I exercise[1] I not only burn calories but increase muscle mass which burns more calories. Other people seem to do well with a focus on diet and not so much exercise. Weight loss should be about losing weight in a healthy, sustainable way, however that works out for the individual. To continue doing something that's not working because it's supposed to be The Right Way is counterproductive and demotivating. I think most people can find some balance between eating healthier/less and exercising more, in a way they can keep up.

1. I've only had two effective exercise regimens: resistance training (weight lifting) and martial arts. If I try to jog, walk, or whatever I will become more and more irregular and eventually quit. Other people love to run. Whatever works.

There's a specific incantation required to send the routed ISO orders via BATS as mentioned in the article. I can see how a refactoring might accidentally change that.

With that said, libraries that send orders to exchanges are required by the exchanges to be certified against their expected behaviors. If you want to send routed ISO orders, you have to test that with them. When making changes to said libraries, it can often be good to re-certify to ensure things are still working as expected.
Hi, this is a small demo I made not long ago.
I love to read articles about product, internet, especially from Great people like Paul Graham, Andrew Chen. etc. So I thought about setting up a personal RSS reader, and filter the feeds with Pocket Index, to select out better content for reading. And here is the result.
It's not pretty-looking, but it's useful for me, and I hope this would help you too.
In the README, this description is given of the process:

"When the list of repositories has been compiled, it proceeds to gather all the filenames in each repository and runs them through a series of observers that will flag the files, if they match any patterns of known sensitive files. This step might take a while if the organization is big or if the members have a lot of public repositories."

Digging in to the source code under `/lib/gitrob/observers/`, you'll find `sensitive_files.rb` [1]. It looks like this class loads patterns from `patterns.json` [2]. This file contains patterns that match common sensitive files like private key files, common configuration files, command history files, and config files. It has the ability to match by path, filename, or extension.

No tool can look at a file and say for sure if it contains sensitive information, but this list looks like a good start for flagging common mistakes. I'm sure the author would appreciate pull requests to patterns.json as well.

I know people don't want to hear it but private prisons are only 8%, but keep on believing what you need to.
I've been doing that and have seen pretty steady drops too. Since June when I started, I've dropped 11kg, with a rate of about 0.9kg per week. Asides from one weekend when I went to visit friends in the UK for a Real Ale Train trip, and a couple of slices of fudge cake in the office, pretty much the closest thing to processed sugar I've been consuming is some honey on soda bread in the evening. Once I run out of honey, I'll probably stop with that too.

The biggest thing I've done regarding fruit is getting rid of fruit juice. I don't think fruit itself is so bad, because of the sheer solid mass of the fruit itself. With fruit juice, that's mostly thrown away, and you're consuming what's essentially fructose water, which isn't particularly healthy!
