I do maths as a hobby but I'm very visual/spatial thinker and not good at proofs/jargon. I've also made several math video games (supermathworld.com is the latest).

What I've found is that high interest and aptitude is not enough for community recognition. It seems like a pretty competitive thing, you have to do something significant like prove an unproven theorem to really get "recognition".

But why do you want recognition? Or is your goal just to have more fun?

The argument is not an argument at all, but an appeal to ideology.

Ironically, the ideology that is appealed to is the best argument for net neutrality.
The plastic key fob is totally isolated from any network. If your phone was isolated like this you would need a new phone. Google Authenticator can be cloned if you compromise the device. A plastic key fob that has no input is for all practical purposes impossible to clone and if it's stolen it can be easily revoked.
I wonder if you could make a big drill out of hundreds of hot swappable high torque Tesla motors that were intelligently geared and well mounted. Hot swapping battery packs from the underside of a car via automation was demonstrated years back by Tesla so learnings there could be used. Tesla uses a bunch of widely available 18650s for their packs and benefit from that same modularity, and I imagine big cost savings there for a drill that size even with a great deal of breakage in the array of motors.
WTF! Who raises $5.5B at one go?
> The argument is not an argument at all, but an appeal to ideology.

All arguments for policy (or action more generally) are, at root, appeals to ideology. You can't get "should do" results anywhere else.

Correct. I think Google will be replaced but due to their investment it won't be easy.
Looking from the other direction, say an elevator can handle 60 cars an hour, so given staggered commutes it might serve the needs of 100 drivers. If having elevator access let you cover most of your commute at 100mph, what would that be worth? Multiply by 100 drivers, and 10 more to get from annual revenue to capital expense and I'd say million dollar elevators are no impediment at all.
Agreed to an extent, but I think we're going to have to wait and see what the next four years have in store for us. A lot of being Canadian has to do with... not being American. The only place in Canada where I feel there is a definite core identity (completely separable from "not being american") is Quebec.

Harper being so pro-monarchy, insisting on the War of 1812 as being a national foundational myth, trying to assert soverignty in the North seem to be a realization of this identity problem. Also take the current celebrations for the federation's 150th anniversary: the branding completely skips the fact that there were people in the region calling themselves Canadiens for roughly 200 years prior...

Add to that the recent underwhelming documentary on the country's history done by the CBC and the current Premier's own belief that the country has no core identity (being "post-national").

All in all I believe there's a good chance that Canada as you and I know it today will not be around to celebrate another 100 years.

But they may also host unwanted or even malicious software, firmware, or hardware—and the buyer may not know the difference, or even know what to look for.

Alternatively, the clones are often the ones which will omit the user-hostile DRM and such. Thus you get HDMI splitters which don't actually re-encrypt HDCP, DVD players which don't implement region restrictions or the "unskippable" bits (https://en.wikipedia.org/wiki/User_operation_prohibition ) , Androids with unlocked bootloaders by default, etc.

Of course, to an organisation like the IEEE, who have always appeared to be pro-DRM, pro-IP, pro-copyright, that would probably be considered "malicious"...

The whole safety/security argument, while true, I think is somewhat overblown and these days increasingly used to justify an authoritarian agenda.
“The Righteous Mind” or Why We Can’t Get Along, Part 1
I think it's more nuanced than that.

You can break down the world into the 99% that "know" that it's impossible. They'll never invent that world-changing thing.

That leaves 1% that "don't know" that it's impossible. Of that 1%, 99% will try and fail.

The remaining 1% of the 1% succeed, like George Dantzig (who came late to a Stats class at UC Berkeley, thought some problems on the board were homework, and a few days later handed the professor solutions to some famous open problems in statistics), and Jack Kilby (who, seeing computer performance limited by the number of wires soldered by hand, demonstrated -- against the protests of his "we-know-better" co-workers -- that you could get rid of the wires, resulting in the integrated circuit).

It's important to remember the 99% of the 1%. There are probably people on HN who have tried and failed. But rather than simply saying that it is impossible, we should encourage people to share share how and why the problem is difficult, so that hopefully the next person to try won't waste their time retracing the failures of the previous generation.

No. At least, not in the case of graph computation. This was the conventional wisdom with some people, but circa a year or so ago when we did some measurements, no.

If you don't want to read everything (but you should, before trusting the conclusions), the relevant measurements are here:

Edit: Reading the paper, they cite these measurements and present their work as "only [..] 8.8× slower than a distributed in-memory" system (GraM, a different system than timely dataflow). The quote is on the first page.

UEFI cannot be disabled. The "disable" UI is a big fat fucking lie by morons who think everyone else is a moron, therefore they concoct big fat fucking lies like this one.

What they've done with the "disable" option is enable a compatibility support module for UEFI to present a faux-BIOS to the operating system. The point of a CSM was to provide backward compatibility to legacy operating system that have no idea how to talk to UEFI, but can interface with BIOS.

So all you're doing is using UEFI and also a fake BIOS layer. But they call this "disabling" UEFI. Hence it's a big fat fucking lie. The things liars tell people who they think are stupid. So, you know, you should be a little pissed at people who think you're a moron that you need to be lied to.

"Distantly"?
Apart from the tragedy of the commons problem, it's also hard because we don't know if the benefits will outweigh the costs. As far as I've heard, the science doesn't answer that accurately enough to actually make a decision. We might be better off with global warming than with a premature end to oil and coal.

Bear in mind that global warming isn't the end of the world, it's just a change. Humans will certainly adapt and carry on. The problem is the costs might be inconveniently high - or they might be tolerable.
Xkcd's chart starts a mere 22,000 years ago.

It is not representative of the history of the Earth.

To take just one example, I'm pretty sure that the sudden arrival of the Chicxulub "dinosaur killer" asteroid produced a change in Earth's climate that was vastly more devastating and immensely more rapid than anything we're seeing today.

"Unprecedented", indeed.

Edit: added a few references.

http://www.sciencedirect.com/science/article/pii/S0277379104...

"We revisit the portion of (Nature 391 (1998) 141) devoted to the abrupt temperature increase reconstruction at the Younger Dryas/Preboreal transition...Three quasi-independent approaches employed in this work all give the same result of a +10 °C warming in several decades or less."

http://www.sciencedirect.com/science/article/pii/S0012821X08...

"Here, we report on the second abrupt warming (4 ± 1.5 °C), which occurred at the end of a short lived cooler interval known as the Preboreal Oscillation (11,270 ± 30 B.P.). A rapid snow accumulation increase suggests that the climatic transition may have occurred within a few years."

One ten degree event and one 4 degree event. Both much larger than anything we've seen.

There have been many others. In fact, it is believed that at least 25 such events took place in the last glacial period alone. See: https://en.wikipedia.org/wiki/Dansgaard%E2%80%93Oeschger_eve...
I'm not that person, but I think the Facebook meme pages fill a specific niche that Yik Yak had their hands in.

Yik Yak had this market cornered for a long time, but because of some dumb decisions it's mostly dead now

Considering that the language made huge strides forward with ES2015, ES2016, and ES2017, what does that mean?

Spirited debates about JS vs. OCaml are implementation thinking.
> I think you are conflating surplus with utility. Full flights have more utility than not full flights...but the market surplus available is unaltered.

Utility is quantity that is measured with respect to an individual (subjective), whereas surplus is an objective measure. This is but one difference, and I am not conflating them. Fuller flights (less dead-weight loss) means there is more surplus to go around, and which will in general be divided up between the buyers and sellers.

I could say similar things about your understanding of price discrimination. My guess is that most of your confusion comes from thinking in terms of an idealized model where prices are dominated by marginal costs, whereas fixed costs for planes are very large.

This can all be inferred from the definitions you link to, you just haven't internalized them.
If subways are already as tight as sardine cans, how would giving everybody in that train a full car full of room even be the slightest bit possible? There just isn't enough physical room in the tunnels for that.
Yeah, compare the BART to the subway in Stockholm and it's night and day. Nice public transport is absolutely possible. I remember the first time I lived in the Bay Area they were building BART and I had these expectations... And then years later when I rode it for the first time, I wondered why public transport this close to the center of the tech universe was so shitty. I mean, the trains in Europe have wifi and are clean and beautiful and comfortable and quiet. They're also secure, mostly because of how they handle as a society the kinds of people that make public transit a bad experience. It is astonishing to me that we don't have and can't have nice things in the United States.

I gave up at being 100% on 5s, 95% on 7s, and 80% on 8s. For someone like myself who's not a naturally talented anagrammer, the workload to just maintain what I had learned got to be too much.

> Mostly because they live/work in areas that aren't dense enough to have good last-mile public transit, and they don't want to deal with transfers.

Well, suburbanization was a totally dumbass move. Maybe instead of building tunnels, we could be rebuilding cities. We could be designing them to be attractive enough that people would want to live there.

I actually think the Viva system in York Region, Ontario, Canada is a great model for this.

Highway 7 started as a car-only multi-lane highway. They took a multi-phase approach to building out a light-rail system. The first phase was adding bus rapid transit, increasing fares, and increasing density of new construction. The second phase was adding dedicated bus lanes and light-rail-ready stations. The final phase will be to add tracks and trains on top of the road.

I've worked through most of my packaging and pyenv/virtualenv issues but I must say I found it much more convoluted and painful than any other language I've worked with in the past 6 years. The need for all the virtualenv's makes me sad, and I'm not a huge fan of the shim system. Working on multiple projects that need different versions of a dependency, particularly when your also working on that dependency, can be a pain still. This is very subjective but pipenv was just released THIS YEAR and has over 3k stars on github; clearly there is some general angst out there.

But I more meant the ecosystem in general:

A "batteries included" language makes me create my own UTC tzinfo implementation so I can get a datetime in UTC... Python's time situation is maddening and by far the worst I've worked with. I'm sure others feel this way because there are a bakers dozen of time libraries trying to fill the gaps.

I almost rage quit the industry trying to save and retrieve a UTC datetime from the database with sqlalchemy. Luckily I found Arrow and ArrowType and that's been working well enough for now.

On the subject of time this has been open for close to five years?
https://bugs.python.org/issue15873 . I get the impression that lots of proposed improvements are languishing like this.

sqlalchemy and alembic feel like JUST ONE GUY is working on them. Massive achievement, but the gaps are visible.

The module system feels stale; a holdout of a system from different workflow times. Splitting stuff off into separate files for maintainability(including improving multi-dev workflows trying to reduce conflicts) creates some gross imports.

It feels like there is a reluctance to evolve the language itself; a lot of enhancements appear to be made via more magic metaprogramming and function usage. super(Cls, self).__init__() comes off as an artifact of this. Not really my cup of tea these days, but I can see how this is very subjective.

The propper way to handle generated members with pylint is supposedly a plugin; which almost no projects provide.

Type annotations are supposed to go a long way in 3.x, but the prevalence of metaprogramming and lack of tooling awareness has probably defeated more jedi than Darth Vader.

boto3 has no official async support even though lambda just released support for Python 3.6. Meanwhile the javascript sdk is shipping with TypeScript definitions and a new promise interface.

A lot of this is very subjective(other than perhaps the languishing of certain library areas) of course. To me though, after having worked with a lot of other languages, it just feels like Python is a bit of a ghetto these days. It's like the language world has built north and Python is.. Not living to the north.

There would be benefits to licensing web dev. I wouldn't suggest that a license should be required for any web development but if the website is used to safeguard PII or secure financial transactions then I don't think it would be too unreasonable to do so to get rid of these clowns. I used to work in an SMB web development shop and the incompetence that I'd see daily from our competition really changed my perspective on the field.

I used to feel almost like an imposter when I first started but I've seen so many "experts" who have been selling their services for decades yet they don't understand even the fundamentals of their profession. We already require licensing professionals for many things which are arguably less important than a lot of websites. I think a fair balance could be struck here to make sure that large businesses like Betfair can't get away with this crap yet not stifle hobbyists or businesses whose websites don't pose any appreciable risk.
Java Clean Code – Methods
Ask HN: Found stolen code in our Git repo. What should I do?
I work at a startup founded by a former Google engineer. He claims to have single-handedly written the original software before raising VC money to build a team. I was super impressed by our CEO's technical talent and incredible productivity. But I recently found from the git history that many files had Google's copyright notice and authorship annotations before they got deleted by the CEO.

Should I confront him? Should I contact the press? Should I inform our investors? Should I get in touch with Google? (Will they even care? We're not Uber. We are a tiny startup in a market they chose not to enter.) Should I just look for another job?

What should I do? What are your thoughts? I really need guidance, thanks!

I think JS ecosystem is an order of magnitude more unstable. I can still write a Django/Flask/Pyramid app in roughly the same way I did 5 years ago. The key libraries have longer and more consistent development. The whole environment is just easier to use. Maybe I am biased from nearly a decade of heavy Pyhton use, but I have written a non-trivial amount of JS code. Angular 1 is basically a relic. It just isn't a user friendly sandbox to play in. Python has its warts but we build and use tools in Python and it seems much easier than JS.
