> There's something I don't understand in this statement and in GP's story: when you stay static in the water, provided you don't carry extra weight, you just naturally go up and float to the surface. If you want to stay down, you have to actively move in order to counter Archimedes' force.

If you've got a lungful of air. Exhale first, and most people will sink like a stone.

My Dad had a trick, which I've done a few times myself as an adult, where he'd hyperventilate for a bit to get his blood heavily oxygenated, then exhale fully and just lie quietly on the bottom of the pool for a minute or so. (In the shallow end, so he only needed to stand up to breathe.) It's surprisingly soothing; after reading this thread, though, I'm not sure I'd do it at a public pool to avoid freaking out the lifeguard, and I certainly wouldn't teach any kids to do it.

(Floatation also depends a lot on your body fat percentage. Babies are very chubby, so they float, but I can imagine that a real lean kid in the middle of a growth spurt wouldn't be so buoyant.)

This is very wise.

You try to make the best architectural decision that you can at the time, with the knowledge and resources you have available. Time passes and you learn new things -- maybe the problem changes, or your understanding of it improves, or your understanding of alternative implementation strategies improves. For whatever reason, you can now imagine a new architecture that would be superior, if only it were implemented to replace the old architecture. Now you have technical debt. This doesn't necessarily mean that the best decision now is to pay off the debt by reworking the architecture -- that depends upon a cost/benefit/opportunity cost analysis.

edit:

Tangentially, there's a pretty interesting presentation by Kevlin Henney titled "The Architecture of Uncertainty" [1]. My poor summary: When designing the initial architecture of a system, Kevlin suggests that the team brainstorm to identify which parts of the system have a lot of uncertainty. Each region of uncertainty then becomes a subsystem. Put interfaces between the subsystems that need to be connected. Hopefully you now have an architecture with stable interfaces, even if individual subsystems need to be completely rewritten during the course of the project.

Are there any examples around of combining Bootstrap and Flexbox; i.e. relying on Flexbox for layout and NOT using Bootstrap's grid, but using Bootstrap's other components... is that practical without a significant rewrite of Bootstrap (i.e. do the component styles make lots of assumptions about being sited within the Bootstrap grid).
Thanks for doing this.

Sometime back I tried to develop habit of listening to podcasts about startups while working out. I gave up finally when I realized most podcasts I find on web on related topic are with people who are trying to sell something (mostly book).

Any other good sources on podcasts with founders that are not trying to sell their book?
I'm curious about this. Does something like wxWidgets offer all widgets that are available in an OS?

Does it offer the files listing widget the Mac has in that fourth mode, where flipping between files shows on top an extra area that feels like flipping between music CDs?

I guess the point is, what do you do with widgets available in one OS that aren't available in another? Should UI libraries keep up?
> Well, it does offer the functionality of being usable integrated environment, which I know a lot of the emacs/vi people dismiss

Maybe the vi people do, but I'm not sure about the Emacs people, seeing as SLIME is the modern day free integrated environment for Common Lisp programming.

Regardless, my point was less about the superiority of Emacs and more that Emacs is the oft-cited textbook example of a "bloated" program (as per the "Emacs is an excellent operating system; too bad it's missing a good editor" joke), yet is dwarfed in size by the likes of VS and Eclipse while having parity or near-parity functionality-wise.
It would take an extraordinary effort. I doubt there is anyone who could learn this material given anything less than a year of solid study -- and I am thinking of the leading researchers in the world, who are already experts in everything related. I am a professional mathematician myself, and I doubt I could manage it even within a year.

This is dictated by the difficulty of the subject, and it is even more so since Mochizuki's papers are notoriously difficult to read. What I have heard from other research mathematicians is that Mochizuki doesn't make much of an effort to make himself comprehensible, to answer questions, or in general to explain his results to the community.

Also please be warned that the consensus is generally that Mochizuki's theory is probably incorrect.

That said, if you want to learn the stuff, there is no reference other than Mochizuki's papers themselves. If you would like to learn some general background theory I would recommend learning some algebraic geometry, for which see Ravi Vakil's book:

http://math.stanford.edu/~vakil/216blog/FOAGapr2915public.pd...

and maybe Milne on etale cohmology:

http://www.jmilne.org/math/CourseNotes/LEC210.pdf

If you find that incomprehensible, start with Dummit and Foote's Abstract Algebra (read it cover to cover), Neukirch's Algebraic Number Theory, Atiyah and Macdonald's Commutative Algebra, and Fulton and Harris's Representation Theory.

If you indeed want to read all that, you may as well enroll in a Ph.D. program in math....

Your comment would have more value if you provided a specific example. Which philosophers refuse to consider scientific evidence? Is the scientific evidence conclusive enough? Does it mean the entire subfield of philosophy of mind is in crisis?
I'd rather say the science of mind is in crisis, since we still have no good scientific explanation of intelligence, consciousness, or how a brain works in general.
I have heard that the current system woefully misallocates bandwidth and that Full Frequency Spread Spectrum transmission would help with that.

For all the great ingestion capabilities of rsync.net, their pricing still isn't nearly competitive with any of the cloud storage services.

Could someone from rsync.net explain why? Am I looking at rsync.net the wrong way? Is it meant to serve a different use case?

The front page of the website says "Cloud Storage for Offsite Backups" but the pricing shows that it costs 8-20c/month depending on usage. Meanwhile GCS Nearline and Amazon Glacier (also offsite backup products) are at 1c/GB and even their regular storage is at ~3c.

Sell me. What does rsync.net offer me that justifies an 8x-20x price bump?
Yeah I bet. Jeans are pretty fun. They get amazingly heavy and restrictive.
So I took a look at those. I can't argue with the Ars article on batteries, although I wonder if it's really worth using Li-Ion batteries for homes when lead-acid is super simple, and I think cheap, (I'm not sure if the acid's recyclable, though).

The first linked article talks about storage, not generation - is it the correct link? If we can get solar into the $0.02 - $0.04 range we'll have largely won the battle.

On shrinking wilderness, I'm not sure about some of the methodology in that paper. For land use in agriculture it seems to have tailored the timescale studied to support the theory that we're using less land for agriculture, but even the selective charts show we're almost at peak corn acreage and headed up-and-to-the-right. The argument about saying cubic yards of wood production per hectare of forest is going up was missing a timescale, and charting wood used per dollar of GDP doesn't really tell us anything about how much wood is actually being used, it just makes a chart that looks like its heading in the right direction. I think the US may be seeing less land under agriculture, but I think a lot more food is being imported from Central & South America, and Asia, areas that were not discussed in relation to area under agriculture. I didn't look up the reputation of thebreakthrough.org, but the paper read somewhat like a "we're doing fine - stop worrying" study influenced by parties that don't want rapid change.

There have been some major wins on the wilderness vs. non-wilderness front, though. Many waterways in North America is probably cleaner than it was 30 years ago, (think of the Great Lakes, and around NYC. I'm not sure about the Mississippi, Columbia, or Colorado river systems). Acid rain on the east coast & central Canada has largely been dealt with, and some species are even coming back to places they've been gone from for years, (I caught a salmon on vacation in BC last year for the first time in 20 years).
Beyond Reformatting: More Code Cleanup
I was fascinated by the link[1] in this line "As a result, instead of being hostile to fuzzing, Firefox developers actively help me fuzz their code."

It almost reads like a parody, but it's clearly quite serious; a detailed, thoughtful discussion of how you can ensure your continued ability to ship buggy products. (I know, that's not how the authors see it. But I know which philosophy I hope the people developing the software I have to use have, and it looks a lot more like Firefox than RIM.)

Its quite easy to build unhackable software. It just also happens to be unuseful. Its always a tradeoff.

NTSB preliminary report about F16 and C150 collision
What a great story. It's so nice to see real philanthropists: people helping others before helping themselves. In the Tech industry, many startups claim they will make a change and make the world better when they actually think that they will make their own life better.
This woman is a perfect example how the Tech industry can give to others directly.
> Phones and cloud services aren't in competition, they're complimentary services -- phones create demand for cloud services.

Sure, from the standpoint that devices create demand for computing services, which these days are delivered via the cloud. But there's a lot less of an inherent advantage that Microsoft has in that environment.

On top of that, the money to be made is a lot lower. Let's throw out a scenario here - Microsoft trades its OS dominance for a dominance in cloud computing. They lose all of their OS revenue (unlikely to happen) in exchange for having a huge chunk of the cloud computing market (also unlikely to happen).

If we model this out - Amazon AWS in 2015 will make roughly $6b in revenue, which is about 10% of the total public cloud market in 2015 according to IDC In 2018, this market is supposed to be 128b. Let's say that Microsoft in 2018 has 2x Amazon's current market share, which would be a huge success by any measure, that gives them ~$24b in revenue.

Which is half of what they made in business software licensing in 2014. Half. They made 40 billion just on the business licensing end of their traditional software business.

I fully believe Microsoft will continue to live and innovate and potentially succeed in this brave new world, but it will do so at a huge long-term impact to its revenue and size.
Or it could be a testament to how little real-world use Plan 9 saw. This is the same reason Latin doesn't change.
One example of an app you'd want to run on ethereum is something like a prediction market (PM). A PM is a pretty general financial market and can be used to speculate on things from "Who will become the US President in 2016?" to "Will Russia invade Estonia by 2020?" to "Will American Pharoah win the Triple Crown?"

Ethereum is useful for this because it allows for distributed custody of funds. No one controls the funds stored in these contracts, so there's no one to run away with and steal all the money, and, since it's run on Ethereum, there's no middleman taking 5-10% fees. In fact, for the first time, we can have a truly global prediction market, and _anyone_ can create markets on it to boot! This is just one app possible on ethereum, and it's one I'm building - www.augur.net if you're interested.

Ethereum's basically a platform that allows you to create "smart contracts" (aka programs) that are practically guaranteed to execute the way you write them. And multiple people can interact with the programs and it'll still be executed the same way. This is a bit abstract, but the main huge advantage this allows is: you can finally send money to some program, and the program will do exactly what it says it will, and no one else can modify the results or even touch your money. Bitcoin allows you to send money around, Ethereum allows you to enter into complex contracts with money, and those contracts are always enforceable.

To take this into the real world, imagine you want to make a bitcoin prediction market. Since you can't run the complicated buy/sell machinery of a prediction market directly on bitcoin, you're forced to take deposits from users, match their orders, and then do payouts accordingly after the event occurs. You can run away with the funds at any time, and there's nothing stopping you. Sure, you could elect to use multisignature wallets or cold storage, but that didn't stop MtGox from happening. Heck, even InTrade, the largest prior prediction market had millions of dollars of funds embezzled by their later CEO.

Now with Ethereum, we can send funds to a contract, they're stored there. You can buy and sell and all orders go through the contract. At the end payouts are done by the code in the contract, and no one can take the funds held in the contract.
Where did you read "1000x cheaper"?
And they say comparing to SSD and HDD it will not be cheaper but faster and comparing to RAM it will be cheaper but not faster.
First, those are completely different standards of safety. If airplanes felt as often as surgery fails, people would not travel on them all the time. Even radical sports are much safer than surgery.

Also, pilots must sustain a good enough performance for hours, while surgeons must sustain a great performance for minutes. Those are very different requirements, and may quite well fit different personalities.
Right, but my point is that we're not quite at the point where a computer can reasonably process that much visual input, determine whether or not something is exhibiting the signs of drowning, and alert a lifeguard with a minimum of errors. False positives will lead to personnel confusion, and false negatives will lead to dead swimmers.

This isn't to mention that automation does encourage complacency. One of the primary reasons for the recent Malaysia Air jet disappearances according to investigations is an excessive reliance upon automated systems to fly planes, and insufficient knowledge of flying without such tools. I reckon a similar situation could be a real danger here as well (if not amplified considerably; most lifeguards (at least where I've lived) were usually highschool students doing it as an extracurricular/volunteer activity, summer job, etc., and teenagers aren't exactly known for having an above-average attention span).

Cool, thank you for the concrete number.
It is a breach, but only a severe one if there were things (of import) for which another plausible excuse could not have been trivially constructed. And again, this is an issue because individuals cannot credibly be secure, which is quite specifically something the NSA has worked to ensure.

Native emulation has been a goal of the web from the beginning. I can recall several efforts as far back as '96 to create websites to replace desktop apps and we arguably achieved that around 2005 with apps like Google Maps or Writely. Two years before the iPhone was released we were chasing the tail of "native". The web vs native debate skips over the idea that these two worlds actually inform each other and are largely populated by the same developer community.

As an industry, I think people are starting to place more value on the comprehensibility of software over its capability and that's where I think PPK hits home here. When you're building to satisfy immediate needs it makes sense to eventually stop and revisit your implementation to make sure (1) those needs are still relevant and (2) your implementation adequately satisfies them. That's what I see this as, not a call to stop chasing native, but a call for replacing the patchwork with comprehensible design. I think that's perfectly reasonable and I would go so far as to say we should build it in as a cultural value to pause every 10 years to both celebrate what we've accomplished and refine the result.

The fact is that there is a greater East-West struggle going on right now. It was Saddam. Now it is Assad. Next it may be Rouhani.
