If anyone is interested in how mathematicians think and do proofs there are many helpful books. For example,

Mathematical Proofs: A Transition to Advanced Mathematics by Chartrand and others.

How to Prove It: A Structured Approach by Velleman.

Learning to Reason: An Introduction to Logic, Sets, and Relations by Nancy Rodgers.

Elementary Discrete Math books make for great intro to proofs and math thought:

Discrete Mathematics with Applications by Epp.

Mathematics: A Discrete Introduction by Scheinerman.

There are tons of terrific introductory books on other subjects in math if anyone's interested.

"start meditating"

Research has not shown that meditation beats a placebo

To be clear, I'm not generally a fan of infinite scrolling either.

I'm not sure it is possible to talk about this in general terms - the specific use-case needs to be considered. In the case of Wikipedia, I think that the page size of a typical Wikipedia page isn't problematic.

I suspect it's actually pretty rare that the HTTP response size for text documents is big enough to be a problem. 1M of text is pretty large in terms of text, and most pages would have more than that in embedded images.

Pretty sure quite a lot of people out there would rather take more frequent, good sex over something rather superficial as broader shoulders. Sex can be extremely pleasant especially if all parties feel like it and are longing for each other. Getting older the opportunities for such sex can become less frequent though, and an increased sex drive could help to counter that. Not sure taking drugs is the best way to achieve that though..
Alcohol, plastics (which leech from containers into the liquid they contain), pesticides (on fruits, vegetables)—there are a host of environmental factors that reduce our testosterone levels.

And as for anxiety, I think our modern urban lifestyle far increases our anxiety levels compared to our ancestors.

Since Perl 5 doesn't have a GIL, I doubt any of the Perl 6s will. Threaded Perl has been a thing for 15 years or so. It's not something to "solve", either your interpreter is reentrant, or it isn't.

But spawning threads in your Perl code comes with the same set of problems as anywhere else, it's easy to create races or deadlocks, and Perl happily lets you do these things if you ask it to.

> Isn't that rather a psychological issue? After all, aging is still quite unavoidable. Would postponing the unavoidable end really make you less mortified?

Well, it was merely a way of saying that I worry about aging. No one is questioning the "unavoidable end", really - I am just interested in the idea of aging without losing too much life "quality".

> Sort of the same remark as above. Moreover, it is (afaik) not proven taking any kind of drug will counter or reverse the damage done by sitting all day - so taking drugs anyway would just act as a placebo: it doesn't really help with the actual problem, but you wouldn't feel guilty because you would think it does help. Which is maybe worse than your current situation as you would be less tempted to find a more suitable solution. Which is hard to figure out without knowing your particular situation, but would typically include things such as less continuous sitting, more breaks, more moving around.

As above, please, don't take this as a "personal drama". I'm not really looking for any miracle drug. I get up hourly to stretch and drink water. I workout 4 times a week and do my best to keep nutrition in order. As I said above, I'm just curious; the user "toadi" has an experience which seems interesting, which is (only) what I asked for.

Just a quick remark, this is not strictly true: "would just act as a placebo: it doesn't really help with the actual problem". A placebo can really help with "actual" problems.
>- I didn't get huge muscles or less body fat with more testosterone (huge myth that I thought would change for me)

The many studies done on this subject show that testosterone makes a huge impact on muscle growth. Take this 10 week study for instance, http://www.nejm.org/doi/full/10.1056/NEJM199607043350101. The placebo group working out didn't experience nearly as much muscle gain as those taking testosterone did when they were not working out.

I get the impression that many of the donations are from individuals. That's crazy considering the great work they're doing. They really need a sugar daddy, like the big G, to fund them.

Compare this with much less ambitious projects where developers gets funded when some company or other commits to it. Perhaps the Euro-centric development holds them back here from getting some of well earned Silicon Valley cash?

I wish I had the slighest idea how to help them, apart from pitching in some beer money. They do truly great work.

I suspect women never really talked about menopause until recent decades, yet they have been experiencing it throughout the existence of our species. (Although there is that traditional "Maiden, Mother, Crone" thing. Hmm.)

Anyway, only recently have men started talking about andropause. The main reason it is still a controversial subject is because men's reproduction systems don't completely shut down, and because the process can sometimes be much slower. However we still go through many of the same hormonal changes and it is rather unnerving.

I think we have only the barest minimum of understanding of the chemical processes that control and regulate our bodies. Jumping on the production a single chemical as the root of all issues is a little ridiculous sounding to me. Especially in light of all of the recent discoveries about our microbiome. (gut bacteria)

It is an insanely complex interplay. Over the next few decades I'm sure our understanding will increase exponentially.

It would indeed be very interesting to compare the spectrum and balance of hormones and microbiome structures from 100 years ago to those typical in the contemporary human. It could be different because of lifestyle and environment, or it could be self regulating, and nearly the same (the perceived differences being cultural).

Seth Godin on the Icarus Deception and Artists
I suppose the .99 psychological pricing works as good as ever (UK and elsewhere).

A somewhat silly angle to this is that while most items are sold with prices in euros and cents, over here automobile fuels are sold with three digits after the euro in the price. I.e. a litre of petrol/gas is 1.399€, not 1.39€. The third nine is generally shown smaller in the price ads. With the volumes of trade being large and margins small, this makes a lot of difference to gas station chains.

This is even more funny because elsewhere even the euro cent is too small. We don't use euro cent coins here; the rationale by government was to reduce the cost of handling small coins. Thus all shopping is rounded to the nearest 5 cents, and this also applies to credit/debit card payments.

Unfortunately, it's not something I have answers to. I guess I just look at the success of something like the Micro Python campaign [0] (also a cool project) and wonder if something similar could be achieved.

There are plenty of companies that could benefit from PyPy doing well though. How many python servers do youtube / reddit etc run? With some investment in PyPy they could reduce their on-going costs. Youtube could easily dump $100k into the PyPy project, so what's stopping them? (I suspect the answer in that case is that Google just aren't interested)

I'm in a startup that doesn't have money to invest in PyPy, but if we we had more cash we'd definitely look at putting some into PyPy (though our use case is the hairy NumPy side of things).

I guess in the case of PyPy it's maybe less interesting to individuals but maybe there's some way of reframing it to make it interesting.

In a way, I'm sort of the target market here, because I use python all the time and I haven't donated to PyPy. So why haven't I donated (other than being quite broke because I'm starting a business)?

I think part of it is the urgency. There are 3 specific campaigns you're running [1] to get funding, along with funding for the general project itself. And the campaigns themselves are great - you have good overviews of the issues that you're solving, a realistic approach and a proven track record of being able to execute. But I don't know when those campaigns started and what the cut-off date is. They sort of feel ongoing and it feels like there's no loss in not donating right now. Compare with something like kickstarter, where you have a date by which if there hasn't been enough funding you may end up losing out on something really cool.

Sorry for the rather rambling brain-dump, but maybe there's some useful perspective here.

Presumably if you go this route you can't enter any organised sporting events or do any form of competitive racing? Just saying, because as you get older, if you start getting some fitness back you'll possibly want to start challenging yourself this way -- look how many vets enter triathlons and marathons, ride gran fondos etc. I'd see supplements like this as a last resort, for when a changed diet/exercise regime etc. haven't worked.

I am guessing because some hormonal changes in mid/elder life will kick in some kind of emotional down that is mostly fillable by children, rather than peer validation and stuff.

That's what I am terrified of. Celibacy allows me to have room to do everything I want to do in life. I'm just terrified I will wake up one day (again) with a hormonal landslide affecting every thought, direction, and attitude I have.

Cats like me though, so there's always that.

Considering the quality of cyanogenmods "stable" releases, never. Hobbyist professionals are still hobbyists and not liable for the damage their code may do.
Instead of using a service like this one (or Hound) that comments directly on pull requests, we chose to integrate the same tools in our build process with Phare (https://github.com/mirego/phare), a command-line tool we built which runs Rubocop, JSHint, JSCS, etc. and exits with a global status.

If the code has coding style violations, the build breaks. Exactly like it would if we pushed a failing test.

Personally, I’m not a fan of the noise generated by comments about coding style on pull requests.
Amazon sells so many different things that it is difficult to find products within a particular niche. When you look for educational toys on Amazon you will not presented with electronic kits (for example) because mostly that is not what a generic customer wants. Even if you go looking for a particular niche it can be very tricky.

There are lots of sites that sell the same products Amazon do but target a particular niche. A brand like RadioShack could use the Amazon backend and only expose a particular type of product that fits within the traditional RadioShack ethos.

Ask HN: Would you implement a decision table library, in 2015?
I would really appreciate the HN's community advice on this topic.
My requirement is to take decisions based on a common mechanism, not a workflow but merely a matching approach via a decision table (the concept has been pushed as a solution since the beginning, refusing rule engines and wishing to get rid of if-else code). The proposed solution is a decision table, with decision conditions (a column) and actions (another column) + some operators (boolean, any, not, business-like) in order to have a reusable library, matching a set of decisions based on a provided decision table and a matching function, semantically free, via decision table definition in XML, decision table manageable in memory, dynamic SQL creation.
However, I do not really support this solution as I think performances, scalability and clustering (if in-memory-table would be used) would be seriously impacted. And the library would then end up as not-so-reusable and force its consumers to workarounds/adaptations/steps-back. Moreover, I see several principles which could be easily broken: KISS (Keep it Stupid Simple), YAGNI (You Ain't Gonna Need It), somehow also PLA (Principle of Least Astonishment). Too many buzz words perhaps, but the alternative would probably be to use an existing product (OpenL Tablets, DTRules, JBoos Drools) or rethink the solution just via Design patterns appliances (if you really don't want to see if-else everywhere).

Would you really implement a decision table library in 2015? Would you actually use decision tables in your application or push for other alternatives?

Thanks a lot!
If it doesn't help more than a placebo, then it doesn't help at all.
Having done both, repeatedly: use Wordpress or another blogging platform (I hear good things about Jekyll but haven't used it).

The feature set issue looks small, but becomes bigger the more time you spend on the single piece of blogging software. And the bigger and more sprawling your homebrew system becomes, the slower it is to add additional features, and the more likely you are to introduce bugs or security issues...

On that subject, security's another major problem. SEO comment spammers are persistent, and if they discover a way that your blogging code isn't secure, they'll hammer you. WP, provided you keep it up to date, has a lot more eyes making sure it's secure than you do.

(Counter-argument: if you're not going to keep the install up to date, don't go WP. You WILL get hacked.)
The logic of these (unelected) representatives boggles the mind.

The question is not if Placebo is an efficient method. We know for sure that it is. The question is if training and practicing meditation is better than doing nothing.

If you don't beat the placebo, it could mean that there's nothing to train and practice.
This could not be further from the truth. I doubt my CS professors would be able to solve a PDE (or algebraic geometry etc etc). Likewise, few math professors would be able to write a parser generator (or code worth a damn).

The narrative that "the internet [is] becoming more crowded" is a gimmick to raise fees. I'm already paying for the capacity I expect to use. My fees should be applied to upgrade capacity. If that model isn't sustainable, there is no business. Microsoft doesn't get to send me a bill for buying the console (hypothetically low margin), but no games (higher margin).

Differently: I pay X dollars per month for a maximum rate. Somewhere along the lines, people (who didn't want to upgrade their networks) started talking about "toll booths", and "bandwidth hogs", saying that there are "capacity" problems, implicitly requiring that my maximum rate for a month - which I can compare easily to alternative providers - be turned into a maximum rate (... based on a model business person, or senior, who checks email twice a week, or some other idealized average subscriber). It was a grift to turn a fungible commodity into a value-added, highly tiered, set of offerings (which I can't differentiate between readily, and so am less able to switch providers), but with larger margins. In short, it's not a surprise to see network neutrality dismantled now that this billing model is completely swallowed.
