7. Conclusion and Future Work

This paper shows the first empirical results of eliminating the Global Interpreter Lock (GIL) in a scripting language through Hardware Transactional Memory (HTM) to improve the multi-thread performance of realistic programs.
We proposed a new automatic mechanism to dynamically adjust the transaction lengths on a per-yield-point basis.
Our mechanism chooses a near optimal tradeoff point between the relative overhead of the instructions to begin andend the transactions and the likelihood of transaction conflicts and footprint overflows. We experimented on the HTM facilities in the mainframe processor IBM zEC12 and the Intel 4th Generation Core processor (Xeon E3-1275 v3).
We evaluated the Ruby NAS Parallel Benchmarks (NPB),the WEBrick HTPP server, and Ruby on Rails. Our results show that HTM achieved up to a 4.4-fold speedup in the Ruby NPB, and 1.6-fold and 1.2-fold speedups in WEBrick and Ruby on Rails, respectively. The dynamic transaction-length adjustment chose the best transaction lengths. On Xeon E3-1275 v3, programs need to run long enough to benefit from the dynamic transaction-length adjustment. From all of these results, we concluded that HTM is an effective approach to achieve higher multi-thread performance compared to the GIL.
Our techniques will be effective also in Python, because our GIL elimination and dynamic transaction-length adjustment do not depend on Ruby. Conflict removal can be specific to each implementation. For example, the original Python implementation (CPython) uses reference counting GC, which will cause many conflicts, while PyPy uses copying GC and thus is more suitable for the GIL elimination through HTM.

Well, this is the part that excites me a lot. Industrial scale production and distribution of a nutritionally sufficient meal could do wonders in the developing world. As of now, even though there are food subsidies for the poor, there are additional expenses (gas, stoves) and wastage involved. And the saved time could be put to work.

A different incarnation of solyent could change the world.

Last time I said this [https://news.ycombinator.com/item?id=7765697], I was surprised I got downvoted into oblivion. I was genuinely curious why this isn't a good idea to take up at the governmental level.
Hilarious - you can't make this stuff up. I thought we were told that organic == better. I can just see it happening:

So, you'd want people to switch to PyPy, not Python 3.
The author is actually coming out mostly in favour of Soylent. The title asks a question and the article tries to answer it.
Thanks, this is all very interesting. I do think there's a bit more to consider though, such as how it's much harder to design walkably compact neighborhoods with arterial roadways than with gridded ones, meaning you might just get fewer cars in the gridded setup.
Maybe "soylent profitable" is the new "ramen profitable" or whatever.

This looks very well thought out and phenomenally useful for general fitness alone, with the potential to handle all sorts of applications, including tennis analysis. It's unfortunate that they're incredibly vague about what "summer launch" means, considering summer is only a few weeks away.

It is also very unfortunate that Android compatibility will not exist for another 4-6 months at the earliest. Focusing on a single mobile platform isn't something that should still be happening these days, especially when Android's market share dwarfs that of iOS. I look at the decision to focus on iOS in 2014 as a highly questionable business decision, at best.

When have you last time bought some video content? The last blue-ray I've legally bought first informed me that if I copy it I can get X years "in federal prison" then forced me to look at the ads lasting more minutes. On my new TV device, just to download the free apps I have to make an account by the manufacturer. Where I live piracy is actually always harder to be done, and that state doesn't even make life easier.
This confuses me too! The first time I ever heard about Solyent, it was this guy who decided to live on it for 30 days. I guess it generates better press than: "I occasionally eat Solyent in moderation, and it's pretty good".
In my experience, it varies both within age groups and between age groups.

I'm seriously considering it, at least as an experiment. I have type 1 diabetes, so I'm constantly trying to figure out how much insulin to take -- and I don't always get it right. This is mostly a matter of judging the food I'm consuming, but not completely; there's also endocrine issues which affect blood glucose levels (usually pushing them up), and exercise usually pulls blood glucose levels down.

I think having a "standard diet" which takes food out of the picture would make it much easier to figure out how all the other pieces fit together.
Cool to see you post here! We did draw inspiration from beatrix and a few other competitors in the space while building out this first version.

We understand enough about psychopathy that we can now fairly easily identify it by tests and brain scans. We can also fairly easily identify it in children at a very early age. The symptoms and behaviors are not particularly difficult to pick out. It's obviously very real. Unless you're suggesting child psychopaths have learned how to alter their own brains such that their brain scans look different than normal children and they are capable at the age of six of faking psychopathic behavior every day of their lives.

I suggest you upgrade your knowledge on the topic.

We've been around for 2 and a half years in this space. We do something very similar, but we have our own twist on it.

Just like FreshPost.io and Beatrix, we scour the internet for the latest news and blog posts based on your keywords. However, unlike those offerings, we go the extra mile and actually manually evaluate the content against your specific social media writing guidelines and we then draft a post for you to approve.

We're more like your own human social media assistant and ghostwriter. We're also more expensive, but you get what you pay for.

Over the years we have found that many of our customers really just want someone to handle it all directly, so we've recently started offering social media management services in a more traditional capacity.

Ultimately, It's nice to see more competition in this space.

FreshPost.io - your site looks great, although I don't see a link to your Facebook so I can evaluate how good your content is? Any links to see real results?

A New “Theory of Everything”: Reality Emerges from Cosmic Copyright Law
I think it could find a big market in people who care A LOT about eating specific nutrient proportions.

I'm working on the website Eat This Much (http://www.eatthismuch.com) and a huge portion of our audience are people that want to eat EXACTLY 40% of their calories from carbs, 30% from fat, and 30% from protein (that's part of the zone diet, as an example). Our meal plan generator allows you to request those proportions, but sometimes it can't meet the exact targets due to any number of other constraints, and it's a huge source of complaints from our users. It's a pretty complicated problem to solve while trying to give people a varied and interesting diet with real food, but Soylent makes it very simple. I use my own site as much as possible, and I'm excited to have it give me half of my calories from Soylent (probably my breakfast and lunch).
When reading both stories, I can't help but think the greatest problem with Python 2/3 is that there are supporters of both and that it splits somehow (not necessarily evenly) the community.

JavaScript, in the meantime, buried its proper version to prevent just that.

Thanks for the candid reply. Some juvenile part of me was hoping you'd say it was now a colorless, odorless gel.

What prompted the question is the recent spate of articles on gut flora. That was the first thing I thought of when I heard of Soylent--what does it do to your microbiome? If anyone can speak or speculate knowledgeably on the topic, I'm curious.
They're not supposed to be used when it's wet outside.
Yes it is, however not in excel. (written so a non tech person could understand)
There is no magic discovery about the nature of man hidden away in that data. Nothing you're average stand up comedian hasn't already written a bit about.
Yeah. I have trouble remembering to eat meals regularly - I guess I sort of just don't really like eating? - and Ensure is available at the drug store. It's perfect for that "oh crap I haven't eaten in 24 hours and my problem-solving skills are too compromised by low blood-sugar to figure out how to prepare or buy something that isn't garbage" state that I get into periodically. I'll try Soylent, but I don't see what's revolutionary about it.
This was touched on in the article but I still feel it's necessary to point out that nutrition is one of the least understood fields in science.

The primary reason is that there are almost zero proper clinical trials and interventional studies. We have thousands of cohort studies which prove almost nothing.

For example, for 60 years saturated fat has been considered the enemy of cardiovascular health (because of some poorly conducted cohort studies in the 60's and 70's). Just this March, BMJ published a major meta study that showing that there are no proven causal links between saturated fat and heart disease. In fact it is now being suggested that avoiding saturated fat has been detrimental because Americans have replaced fat intake with high glycemic index foods causing obesity and T2D.

Personally I have no doubt that Soylent will fail to provide some required nutrient or fail to induce a certain hormonal or chemical response which is obtained via natural food intake. We simply don't understand nutrition well enough to check all the boxes. That said, if Soylent wanted to follow the scientific method and conduct a proper interventional clinical trial with a control group, adequate study population and duration I would be happy to consider the results.
If it were only syntax, 2to3 would be the answer. Exceptions and Print are not the problem. Migrating unicode-aware code and CPython extensions is a much bigger task, and incidentally, much more useful.

nonlocal, asyncio, unicode, yield from. If you ask me, these four are very compelling reasons to switch to Python 3 and they solve very real problems.

You'll know how to manage your condition better than others but I'll point out that there is talk about a rather high GI for soylent thanks to the maltodextrin. Which could possibly mean it's not suited for you (or rather you might have to have a lot of smaller meals). Alternatively you could lookup DIY soylent and roll your own more appropriate recipe.

If you see code that checks for every possible type of exception or input error, do you think that code is secretly hoping that an exception occurs? Or do you just think the programmer is trying to cover all the bases so he/she can decide what happens when an error occurs?

Contracts are just the 'source code' that define agreements. There's nothing wrong with very specific and precise language. Granted, since contracts are tied to negotiation, some people can be over-aggressive, but mostly long contracts just come from people who have gotten burned before, and have no desire to be burned again.
Using the oil packets and purchasing the most cost effective plan (28 bags for 255/month), Soylent gives you 220 calories per dollar. For a relatively sedentary averaged sized adult male (2100 calories/day), it will cost you about $285/month.

Ensure powder from Amazon[0] gets you to about 205 calories per dollar, which comes to $305/month for the same adult male. I don't buy the 'it's a lot cheaper than Ensure' line.

Another competitor, "Optimum Nutrition Serious Mass" is on Amazon in 12 pound bags for $49. It works out to 408 calories per dollar. Only $154/month for the same example male.

Admittedly Ensure and Serious Mass have different marketing than Soylent (Ensure for old people and Serious Mass for bodybuilders), but if you compare their ingredients you'll find they aren't very different.

Article date is Jun 1, 2014. Is the author from the future?
You're not supposed to talk about the four men he killed, including the three he stabbed to death. It ruins the script.
The explicitly stated purpose of Soylent is NOT to live on. NOT to "End Food". It is to be a better occasional meal replacement. It's a nice improvement on many boring products that preceded it (Ensure, etc). But, that doesn't make for good linkbait headlines nor revenue-generating eyeballs on sidewall ads. This is yet another in a long series of manufactured-controversy articles propping up Soylent as either the Savior or the Devil. YOU DECIDE!

Not that I mind. I'm a backer of Soylent. When my month's supply arrives, I'm looking forward to living on it 100% for 30 days for a few reasons:

1) I need to lose a bit of weight. I know that for me, the best way to do that is to significantly change my "generally good but occasionally indulgent" diet. I know from experience that I can't willpower that into happening. But, I think that if I commit to a defined, strict diet, I stand a chance. Soylent should be particularly good for that because supposedly it won't leave me with carb/protein/fat cravings like every other diet I've tried.

2) I like the idea of going on a cleanse. What better cleanse than supposedly exactly what your body needs and nothing else?

3) I'm interested in the chemical science vs. mystical vitalism theory of nutrition debate. I.e. do we need certain chemicals or do we need "something to do with Real Food" to thrive? Supposedly, people feel really fine living on Soylent. I want to see for myself first-hand. I plan to get my "blood work" numbers measured before and after.
Wow. So what are the times when one would choose one reading over another?
I recently tried to deploy a desktop app written in Python. It was a nightmare. I recently taught scientific Python to prospective switchers. The installation step was a nightmare.

We really need pip wheels or conda to become mainstream. Pip alone doesn't cut it on platforms without compilers (Windows / OSX). Standalone installers are fine, but they don't resolve dependencies and they are only available for Windows.

I totally agree that the installation and deployment story should be a top priority. Once done, it would be another very compelling point on Python 3's feature list.

I'm glad that there are people out there thinking about these things. I've witnessed first hand some pretty amazing limb functionality improvements through nerve repair and definitely understand his confidence in that realm. However, I can't think of a scenario in which testing this really could be justified. The one that comes to mind first, of course, is a quadriplegic. But really, we'd be putting a real person through an incredibly traumatic procedure with a high likelihood of fatality for a chance at motility. I don't think there'd be much support for that.

Just because the ad says you'll want to live on Soylent, doesn't mean you would.

There's a certain kind of people who like to buy into simple formulas for health, success and so on. There are more of them than it's comfortable to admit.

The ad is worded to appeal to them, because after all Soylent is a business, and which business would ignore the large segment of the market that'll be buying your product regularly, every single day?

For those who are more balanced thinkers, Soylent remains an interesting option when you need to have a meal on the go. Better than fast food.

A side reminded, just like with vitamin pills, you should be skeptical of some of the claims made about Soylent's ingredients. Say, just because a product has calcium in some form doesn't mean your body can assimilate it in that form.

for some openings, the 'paths' do not really matter. You might have 25 transpositions leading up to the same position after 10 moves. A well known example is the classic isolated d4 pawn position that might come from:
- Nimzo Indian
- Caro-Kann Panov
- QGD
- Slav
- c3 Sicilian
- Alekhine's defence
and others.

Popularity has not a lot to do with the openings themselves but with other things like a good book being published, or a popular match (like WC).

Another thing you have is that some variations are really popular, and have good results, but are at one point refuted by a single game. As a result of this, the variation dies. but remains to have very good statistics.
