I would think something attached to gloves might be easier to spot than something attached to a bicycle.

That said, I can't imagine a situation where you could see a cyclist but not see them indicating. If anything, signalling makes the cyclist more visible and obvious.

In theory, the EU requires you to collect VAT from EU citizens regardless of where you yourself are based.

The new rules state that you should charge VAT at the customer's local rate, so being based in a tax haven wouldn't - again, in theory - do you any good.

How on earth they ever intend to enforce any of this against the rest of the world is anyone's guess.
All this knowledge and unfortunately, zero sign of any real policy change.
I think what Dan was trying to nudge you towards was sharing some of your knowledge with us, and starting some good discussion on those topics.
For me F#'s syntax is so clean and pleasant to look at, I just love it. But having been in the JVM land for too long, at the beginning I like to get a bit more 'native' and learn OCaml. Hopefully acquired functional programming knowledge can be transferred to F#+Xamarin app development later.
I'd say the MongoDB folks made a pretty safe choice here, since WiredTiger offers both LSM and Btree engines. I've recently completed some more benchmarks on all of the above-tested engines, and will be publishing the report soon (as soon as it's done being written...). Testing on-disk, with DBs 5x larger than RAM, at data sizes of 24, 96, 384, 768, 2000, and 4000 bytes per record. The important result to note is that LSM's high write speed advantage only exists for small record sizes, and for short durations. On long duration tests the compaction overhead stops them in their tracks, and at data sizes above 2000 bytes per record, LSM write amplification is too expensive (regardless of test duration). I.e., above 2000 byte records, Btrees are always faster than LSMs.

This result is particularly relevant for MongoDB, since a document store tends to have large records containing multiple fields, as opposed to individual values being stored as separate small records.

And in cases where that applies (large records), nothing comes anywhere close to LMDB's performance.

(A preview of the on-disk test results I mentioned was presented at BuildStuff.LT last week http://symas.com/mdb/20141120-BuildStuff-Lightning.pdf pages 103-on)
Is the long-term outcome looking like, one day, twenty years from now, we'll be collecting every last sales tax based on where the customer is right this very second?

It seems a bit unfair for the EU to demand e.g. US-based sites to collect VAT, and there not being anything going in the opposite direction.
More cores buys you only so much unless memory bandwidth and preferably number of memory subsystems is also increased (NUMA sockets). It's often easy to consume all L3/memory bandwidth with just one core. A single Haswell core can load over 150 GB of data per second, 64 bytes per cycle.

Wikipedia - and encyclopedias in general - are good sources for established works, not the cutting edge. I think this applies to computer science as well. The CS material on Wikipedia that you would expect to find in an undergrad curriculum is excellent. But the treatment for the research areas I am familiar with is not good. That, however, is to be expected - we're still figuring it out!
> respect the decisions the citizens have taken (in this case, regarding taxes) through democratic ways

Except the citizens haven't taken that decision: the unelected European Commission has.

We could probably go down the reductio ad absurdum road of highlighting their appointment by someone who got elected somewhere along the way, but this powerful body is in no way directly accountable to citizens.

Some of the British North American colonials had a popular mantra of "no taxation without representation", which might appeal in this situation.
Finally.

To me, this looks like a step further away from Flash (used for copying things to the clipboard), which I see as a great thing.

Also, I've been working on a password manager that could dramatically benefit from such an API. I hope that browser vendors will allow synthetic copy/paste (especially copy) events if explicitly allowed by the user (similar to how geolocation APIs work). This would be especially helpful for mobile devices where it's difficult to copy things at the moment.

Except my phone will get itself in a state where that latency stays high, and bandwidth drops for a long time. Only solution is to turn wifi off/on. That definitely seems like a bug.

I'm fine with lower throughput while discovery is going on, but when nothing's changed on the network I've been on for days, and my phone can't use wifi anymore, that's a bug.

It is no small source of acrimony in the University of Cambridge that Manchester beat them to the first stored-program computer by one month with the Baby. However, once the Baby had been demonstrated, it was promptly dismantled, leaving Cambridge's EDSAC with the title of the world's first practical stored-program computer. The EDSAC was then used for nine years at the Mathematical Laboratory before being shut down in favour of the EDSAC 2.

Back when I was doing my degree, the 50th anniversary of the EDSAC came around, and we were given a project of creating a simulator for the machine. This we did, even including the rather interesting sound that the original machine made from a loudspeaker connected across the main mercury delay line. Yes, RAM was implemented as a long tube of mercury with sound pulses travelling down it and fed back into the beginning again.

Your tax-free business is then more profitable than the one that complies with the law, which is unfair. Collecting less taxes would have a detrimental effect in the state, too.
Javascript has superior facilities for scoping, abstraction, and calculation.

Sharing a single scoping system between JS, HTML and CSS removes the need for global symbols (classnames or ids) to link the two together.

Abstractions in preprocessors are implemented by means of macros, and can lead to large file sizes.

My question is can the government actually regulate this kind of thing? As our Greek friend above said, people worked off the books. One might argue that a rational response to the issue is the works to unite against the tyranny. My rebut is that if you're poor, living paycheck to paycheck, you can't unionize because you'll be out of work and starving.

The Tor browser doesn't block ads. Just javascript and flash. His point is the internet is becoming increasingly hostile to privacy. It's already extremely difficult if not impossible to create anonymous accounts with tools like Tor. Which discourages things like whistle blowing, or people from areas with oppressive governments.
The difference between your work and home wifi networks might be multicast settings. Another idea is that at work there's a number of wifi APs on a number of channels, so your devices don't have to switch channels to do the awdl0 broadcast/receive.

I agree with you that incumbent commercial publishers are sucking up a lot of money that could be better spent elsewhere. Where I disagree is on the specific numbers. It's not about the publishing platform or physical printing but the administration of journal's operations. The editorial board and the referees work for "free" (which actually means paid for by someone else, usually universities), but the management and administration does not.

I point to PLoS as essentially the model you're asking for. It's a non-profit publisher started by open-access advocates working as researchers. There are no investors making a profit and they're mission is to spread open-access as a model, and they end up charging $2200+ per article for most of their journals. If that's the number they came up with, then I'm led to believe that that's what it costs to publish a journal, at least in the biosciences. As I said, there are small journals that operate for free, but if you look at large-scale open-access operations, started by idealists, I don't think you're going to find any that sustainably gets by with article charges less than around $1500.

For comparison, when I looked at Elsevier's finances, it seemed that they're charging roughly $5000 per article and half of that goes to their operations and half is profit. So their costs are roughly the same as PLoS, but they charge twice as much in order to make a substantial profit.

As for why I felt the need to correct you, I think it's because I think in general people ignore the real monetary costs associated with open-access publishing. I believe that author-pays open-access is the way of the future, but getting there will mean that researchers will have to find ways to pay these fees when they haven't had to pay before. In principle, this just involves redirecting money from subscriptions to pay author charges and there'd even be money left over, but actually performing that switch across thousands of institutions is not simple. Too often I run into the attitude that for-profit publishing is charging money for a trivial job, and so people wonder why it hasn't been replaced. However, the truth is that they're performing an important and real task with real costs, while also over-charging for it, and that's not going to be replaced overnight.
This particularly applies to those with access to stuff not on JSTOR, which often doesn't get the typical two-hour turnaround of /r/scholar.
For what it's worth, thought I'd drop a bit of my story here since April. I interviewed at Dropbox, ebay, Netflix and others after losing my job. American, FWIW, with a California birth certificate and everything if it matters. Did I get a job offer?

Not a single one.

More than a dozen interviews, zero offers but I can find consulting offers (with far, far lower hourly wage than in 2006-2009 last time I did consulting). I have friends who have been unable to find work also, with skills, experience and blue chip, so to speak, resumes. Somehow saying we need more skilled workers when folks in Silicon Valley with a decade of experience who have worked for, and been given awards by, the biggest names in tech only means that employers want it cheaper.

A friend on an H1B who lost their job? Gainfully employed in less than a month after losing theirs, then again, they have to be seriously motivated else they get shipped away. Until the new immigration policy gets passed where we export jobless Californians to Oregon, my only option was to rebuild a consulting business.

Funniest thing is, now that I'm an "Agency," again, I've had a list of people wanting me to hire them. So it certainly feels like there is a lot more unemployment out there than what I read in the media, at least with my experience...of course, YMMV.
Optimization lessons to learn from the V8 JavaScript engine
That is not my primary point. The point I was trying to make is that the journalist has interviewed one author of a "paper" that is published as a "report" on a biased organizations website. In short, he is trying to feign an appearance of rigor and research where there is none.
> There has been nine price increases since 2001! This has NOT been because of inflation which has been minimal and stable. ... The government never would have raised stamp prices nine times in the last 13 years (based on past history)

A stamp in 2001 was 34 cents. That would be 45 cents in 2013 money.

The same price as a stamp in 1890.

And while you blame USPS for adjusted prices for inflation, it's actually mandated by the government. USPS prices are tied to the CPI-U index by Congress.

So clearly the government is happy to raise prices, since they've mandated this, and they've kept a stamp at roughly 45 cents for over 100 years.

Maybe I am missing something but how could you be subject to collecting taxes for a country that you have nothing to do with? AFAIK, EU laws apply to EU entities. If you are not EU citizen and do not own any EU-registered company, how could they have jurisdiction over you?
This is sort of the key point. There's nothing especially inherently dangerous about heroin, but because of the way it's marketed it attracts people who have been basically rejected by society who don't really care much whether they live or die.

If you marketed caffeine the same way you would see the same patterns of behaviors around coffee, the fact that it's heroin where we see these issues is fairly arbitrary.
I suspect if you're OK at CSS and great at JS, this would have some appeal. Conversely, if you're great with CSS and OK at JS, this will not.

It doesn't help that in most of the examples the Javascript implementation is more complex than the css implementation.

You give a very clear overview of the differences between the languages and I agree it is important to stress that there are significant differences between the two. The OP mentions mobile development though and if the goal is to ship apps targeting iOS and Android, it is not going to be practical to use OCaml- hence my suggestion.

The Collective Mind
For all of the STL's power, and all the useful stuff in std::algorithm, it's still impossible to write something as elegant as a list comprehension in Python. It's really exciting to see Eric's work taking us closer to this goal.

On the other hand, I always worry about all the magic implicit behavior in C++, both in old and new language features. We're writing in C++, we care about efficiency. Eric addresses this by requiring rvalue references in the container algorithms, but in general it's pretty easy to write code that does more work than you expected.

Since most undesired magic in C++ boils down to allocating heap memory unexpectedly, it would be cool to add syntax to could tell the compiler that a block is not allowed to allocate, like:

noalloc {
bigvec = std::move(bigvec) | cont::sort | cont::unique;
}

Whilst I don't know the ins and outs of your business or the implications of non-EU/EEA businesses selling to member state consumers... I'm wondering how such a requirement would be enforceable, given that you are outside the EU? I've yet to see anything that declares a requirement that you must collect VAT - but I have seen HMRC guidance saying that member state businesses selling outside the EU are not affected and don't have to charge/collect VAT, so I'm inclined to believe that it's reciprocal.

A question that occurs for me is how TTIP would affect this situation, though. If TTIP was established, would the EU then require US businesses to collect VAT in the same fashion? Because that would be really sucky for you.
Blocking payment from EU accounts to accounts of firms failing to comply, I guess. That's the standard way to act against firms from shady countries. There are generally cooperation agreements if you're from a developed economy.
I'm surprised bicycles don't try v-belts.

With a standard frame the chain goes through the rear triangle. To install and replace the chain you need to be able to open it at a master link to get it around that piece of the frame. Both the v-belt and frame do best if you don't open them.
Hey, how do you know he's an ass? Because you think he showed poor taste in that article?

You're going too far. "Written so badly," "written by someone with poor taste," call it whatever you will. But don't insult him just because you think his joke was offensive.

Don't forget there's a human being at the other end. Getting this kind of feedback is very discouraging and disappointing.

In fact, it's not even feedback, it's just an insult.

Which, if you ask me, is poor taste.
You would spend more effort wording the questions than a spammer would paying people to solve them on mechanical turk, then storing the answer if it ever comes up again.
"The article author suggests that the Korean laws may not have gone far enough."

That's a really scary line of logic though. "We did a thing, and there was no effect. We propose that to obtain the desired effect we should do even more of the thing that had no effect."

That's undisprovable.

It's possible that doing the thing that produced no results even harder could have some positive effect, but the world is probably even more full of things that produced no results but if pushed harder will have negative effects. Part of being a real scientist is acknowledging that this can only be interpreted as evidence against the idea that forcing shorter work hours will make people happier, no matter how cognitively or emotionally challenging it is. That's being a scientist.

(To forstall the two obvious replies: Consider the difference between the words "evidence" and "proof". And once again, let me underline the scientific dangers in "We tested for X->Y and found no evidence for it, but we're still going to assert that X->Y." This logic doesn't just apply to "work hour reduction", it applies to all null results, of all kinds.)
That is a fair point, in my experience Tor is just used by bots to spam comments up with junk.

This is probably different for larger sites of course but on our scale there's no worries blocking Tor

Actually this is not really new. Since 2003 Businesses outside the EU that sell to private (not business) customers in the EU need to pay VAT to an EU member country.

This is called VAT on e-Services.

Most App Stores (except Google Play) took care of this already but if you did direct sales (e.g. via Paypal, direct payments etc) you need to calculate the tax every quarter and pay it to a member state (which will then distribute it to the other states so that you need to do only one payment).

You can read more on the UK government page:

https://secure.hmce.gov.uk/ecom/voes/welcome.do

The main new thing now is that app stores who had a subsidiary in Luxembourg can no longer funnel it through the lowest VAT country but need to split it up according to the customer country.
