So if right at this moment the world had only enough doctors to care for half the population, regardless of the price, that wouldn't be a shortage of doctors?

If there were a severe drought and only enough food to keep half of us alive, but prices weren't capped... That wouldn't be a food shortage?

If there are only 10,000 people in a field who are under the age of 70 but have at least 20 years of experience, and the industry needs 50,000 of them to function efficiently - that's not a shortage of experienced skilled workers?

Not everything is a commodity. Not every commodity experiences a drop in demand as the price rises. Some things are needs that people continue to have demand for even if they can't afford them due to shortages. Even commodities have limits to their production. And some things can't be produced quickly enough to address a short or medium term shortage.

Markets aren't magic. They have inefficiencies and externalities and logic limits. Econ 101 deals only in simplifications and spherical cows. And people with specific skill sets aren't spherical cows.
That's flawed reasoning IMO. Do they expect the underlying porject maintainers to have the same resources they do to compensate third party vulnerability research?

It really should be the other way around, public facing, revenue generating projects should do all they can to subsidise vulnerability research and upstream their findings. The alternative would be to start paying up more for the code they use from third party and what are the odds of that.
I don't know if it's just me, but this article seems to give a creepy "the USA is the only that matters" vibe. For instance, the sentence "[...] while this may be handy for privacy-savvy Americans, it can make it much harder for the government and law enforcement to fight terrorists and criminals [...]" sounds as if only privacy-savvy USA citizens matter, while privacy-savvy people from the rest of the world can get lost.

Also, the idea of a foreign country being able to disrupt transactions all over the world, with the people having no recourse other than appealing to said foreign country, is creepy. If someone in Austria wants to send money to Brazil, that should be a matter only between Austria and Brazil (or perhaps the rest of the Eurozone, since their currency is shared), and a third-party country shouldn't be able to arbitrarily interfere on a whim.

Belgium is only as large as Italy's Lombardy plus Piedmont, two adjacent regions in the north west. There is no Italian equivalent of a two region pass, but Lombardy has an unlimited monthly pass for all public transportation, bus, metro, regional trains, at 107 Euro, plus an extra 40 Euro to access fast national trains (within Lombardy). Given that an unlimited monthly city pass in Milan is 35 Euro, it's about the same cost of your Belgium ticket. It's for half the area but it's unlimited. Anyway, if we had a region the size of Belgium probably the price wouldn't increase much: people tend to travel close to home.

This seems like the main driver. It seems like you get substantial currency black markets if your artificially pegged exchange rate (for either foreign currency or goods & services) begins drifting from the rate the market will bear. Black market currency trading is arbitrage between an official system and a free market.

Yeah, and better do not forget to cancel those because the friendly DB automatically prolongs these for another year.

In case you refuse to pay, they send a friendly debt collection service -- Infoscore, which conveniently also acts as a credit rating agency.

If you still refuse to pay, the "independent" law firm Haas & Kollegen, which magically resides in the same building as the "independent" debt collection agency and credit rating agency, will take you to court.

Did I mention that these three entities are totally independent, as required by law?
Really it boils down to the fact that (to quote a very insightful comment I can no longer recall the author of) “if I flip a coin and look at it whilst hiding it from your sight, the outcome is perfectly deterministic for me but it is still perfectly random for you” (and, I'll add, the maximum speed at which I can “de-randomise” the outcome for you is by telling you what I measured (at the speed of light)).

First question I would ask: what compiler are you using, and have you audited the binary it spits out. Sometimes it pays to know a little assembly and be able to use a debugger.
Why a few days?

You keep saying this, why does it take a few days to move terabytes?

You're not explaining it at all.

Not only that, with reddit most of that data is historic and unchanging so you can pre-move it.
It looks to be a less complete solution, since it only relies on the LLVM C API which is incomplete. llvmlite digs into the C++ API as well, so while it has more work to do to keep up with changes in LLVM, it's more more feature-complete
I'm just wowed by this not already being part of V8. What else have they been doing?

Don't disagree with you that Bitcoin's current role is small potatoes. Don't disagree that Newsweek (and this author) aren't especially great sources of information.

That being said, writing it off as FUD is premature. The fact that it is getting written tells you where media and possibly government focus is now. We can either write that focus off or consider the implications.

Terrorist and criminal organizations are some of the most effective users of new media in the world. ISIS produces some of the most slickly-produced videos you'll ever see. They know and harness Telegram and other apps. If they are not stupid - and they aren't, they're looking for whatever advantages they can get. We can acknowledge this without a bias for or against cryptos.

The Bitcoin and cryptocurrency community has since birth by and large been about speculation and making stacks of cash. That's been it's reason for existence and adoption practically - otherwise it would just make for really cool tech that we all talk about on HN. It's been running straight ahead with fully anonymous protocols which while great have the most natural application in black market purchases, and early adopters/users that while they have a right to use them, practically don't need to - their actions are tracked via hundreds of other unrelated means.

The cryptocurrency community has done really poor job of policing itself. It's done a really excellent job of attracting attention through exchange after exchange being hacked and/or scams. Maybe it can't and shouldn't try to restraining itself or police itself, but the natural result of that is someone else is going to police it or shut it down.

Instead of just saying it's FUD, this article is probably ahead of the curve. This is going to become a bigger and bigger issue. Either Bitcoin advocates find out effective arguments or means or it's going to get shutdown.

If they really worried about $600 in the Gaza strip, what happens when that turns to $600k and then $6 million? Because that will happen as the technology advances. Does that give governments the right to intervene? No, but it makes a bigger and bigger target.

There might not be an effective solution, but it's the canary in the coal mine. The US government was never just going to let this stuff happen unhindered.

The fact that they are paying attention when there's not much to pay attention to is all you need to know. Just wait until there's a sizable sum a politician can make a media campaign out of...

> I'd also appreciate a link to the explanation of "What in GR we would consider perturbations of dS and IR corrections."

Here's a quick overview of perturbation theory then an example of how one might apply it in GR.

IR is "infrared", low-energy physics, as opposed to UV, "ultraviolet", high-energy physics. In this context, UV means strong gravity where quantum effects are expected to be important. Galaxy-galaxy gravitational lensing (which is the subject of the Brouwer et al. paper that's the subject of the newscientist article linked at the top) is purely a weak gravity problem[1], so is in the IR limit of General Relativity. If you want different results from standard General Relativity you can add corrections by hand in a variety of ways; in the galaxy-galaxy lensing case they would be in the infrared.

[1] strong gravity is hidden behind the event horizons of the black holes of the galaxies and, arguendo, if we could see the strong gravity near the black hole centres, it would not be relevant by virtue of being drowned out by all the stars, gas, dust and other matter.

ETA: This is nice and terse, too: https://www.wikiwand.com/en/Non-exact_solutions_in_general_r...
Cause v correlation. Symptom v disease. We don't struggle with "facts" as much as we too often fail to apply enough critical thinking to get the real story identified and in context.

Humans are shallow. We know this.
Doesn't this assume that as each bug in MRuby becomes more difficult to find, they're also more severe? Couldn't it instead be the opposite, that each bug is less severe because all of the serious ones have been closed?
I really haven't read anything about that. In fact, Venezuela has been issuing debt bonds without any blocks. Are you sure you are talking about Venezuela?
With those lower 'underlying project' bugs there are multiple actors who can compensate for vulnerability research, so the market rate goes down.

It makes sense to either: lower the payout to reflect market rate or start a seperate scheme for those projects that others can buy into. Unfortunately if you use a seperate scheme you end up paying for bugs that don't affect you.

Personally I'd have split my own payouts into things from my own project (100%) and things from other projects (10%).

The fact they haven't done this suggests to me that they consider the bounty system too expensive - either in payouts or maintenance. By reducing payouts you will likely reduce interest and increase signal to noise at the cost of less signal.

"Virtually certain"

You may want to update your confidence. Most of SE Asia has no hygiene laws for restaurants and yet tourists flock and rarely does anything terrible result.

Why would restaurant eating be a race to a bottom? It already can't compete on cost with cooking at home.
What we need is a construction that is as secure as the strongest underlying primitive. For instance, for symmetric encryption: Let M be the secret message, C1 the first cypher, C2 the second cypher, K1 and K2 two randomly generated, independent keys. Oh, and a nonce, but let's ignore that for now.

I Think it is easy to prove that C1(K1, C2(K2, M)) is at least as hard to break as either C1(K1, M) or C2(K2, M). Because if one of the cypher is easy to crack, the other can still work.

Hashes are different, because they're not reversible. In this case, a bad hash could indeed project the input space into a smaller output space than expected, and previous or subsequent hashes cannot reverse this mistake.
Thank you very much! Very insightful

Their web site might give a clue that they produce a parallel debugger and profiler integrated with an (Eclipse PPT-like?) GUI. The debugger is based on launching instances of gdb (which isn't trivial at scale).

More to the point, can someone tell me why I should use the profiler rather than the free/gratis tools, like TAU? Their salesman couldn't.

While a full parallel debugger is clearly useful in difficult cases, easily the most useful debugging tool is stack traces, perhaps from openmpi's automatic backtrace or LLNL's STAT. I don't know whether Totalview (proprietary alternative to DDT) was ever seriously used when we had it available to a multi-site project.

From what I recall of prices, if you're going to buy the tools for more cores than on the sort of single node we have, you're talking something like my salary. Then, in practice most university users won't measure or debug anyway, and may not accept deadlock as a concept when systems people do.
You conveniently miss the part where people are losing money and savings because they cannot exchange the bank notes they had at home before the deadline ends. 30% percent of the population here does not have access to a bank account and cannot deposit the bills.

Are the people living in the most remote parts of the country supposed to make the journey to Caracas to the Central Bank to deposit their money? What are they going to pay the bus ticket with? The worthless paper they are now holding? Are they supposed to travel with a bag full of cash in one of the most dangerous countries in the world?

If you live here in Venezuela you know most workers get paid on Fridays in cash. Now , most are left holding a bunch of worthless paper just because Maduro decided to play improvisation with the economy once again. Those workers now have no money to pay for food till monday.

Why did the government lie and say that the new bills would be in every bank on the 15th? Turns out they just arrived yesterday! The new bills weren't even in the country. Just a small sampling of their incompetence.
Yes, it's generally called an "Opticom" system, as that is one of the more popular ones. The technology has been in use for decades.
That sounds like "Alexander". Interesting.
I had to google this:

>> Betteridge's law of headlines is one name for an adage that states: "Any headline that ends in a question mark can be answered by the word no." It is named after Ian Betteridge, a British technology journalist, although the principle is much older.

Nice, but now someone has to write an article on Betteridge's law headlined "Can this headline be answered by the word 'no'?".

We just have to look at the world of bitcoin mining to see that custom fabricated ASICs would wipe the floor with general purpose CPUs for this kind of task.

I have to agree with the perhaps inappropriately named logicallee. And I'd go further - it's not just a matter of age, nor (as others in this thread have said) of inability or stupidity, if someone works for a salary under market value. I am far from the best at my job in the world, but I'm ok, and for the longest time as a freelancer I charged way under the market (in fact I suspect I still do, though not so egregiously). This was - I think - not because I "overestimated my ability" or anything like that. I was simply not a business-minded person. I was afraid to ask for more. I earned enough to live from, and the rest seemed somehow distasteful to me. I'm not saying this is the ideal, just a fact. And if I have these characteristics, perhaps others do too.
Just last week I bought return tickets from Rome to Milan for the days around Christmas on Italo (the only competitor for high speed trains) and I paid under 50 euros return. Also the distance is not 420 km, but closer to 600 (it's 480 km as the bird flies). And regarding stops, you can get one that doesn't stop at all and it's 2h40 IIRC.
I'd been reading about the mess of privatized rail in the UK for a while, but what really shocked me when I was traveling around Manchester were all the diesel trains. In Germany nearly everything is electric, especially in and around cities.
You can't compare a trip just by length. The total speed of a train is limited by how many stops it needs to make, and the layout of the actual tracks. Having to do lots of curves to avoid populated areas for example can slow a train down considerably. However if you can go through empty land for hundreds of kilometers in a straight line, you can go full throttle for most of it.

One train on google maps for example has 7 stops between Beijing and Shanghai. Meanwhile Hamburg-Munich has 9 stops on a trip half the length.
It reminds me of when the Windows version of Firefox was faster running in WINE than the native Linux one... which then begs the question of whether the same could be true of SQL Server.

...but it's unfortunately not even installable.
average speed is slower due to regular stops. beijing to shanghai seems to stop 5 times. hamburg to munich stops 9 times despite being only 60% of the distance.
Turning them red isn't terribly useful. As you point out, we can already drive through a red light after checking that approaching traffic has stopped.

By turning the light green, it allows cars that might otherwise be obstructing the intersection to proceed through it, clearing a path.
Yes, printing money is the root cause of the inflation.

But no, you can't just make a trivial fix like you said. Venezuela has a dysfunctional government that used to be propped up by oil exports back when oil used to be a highly-priced commodity. After the crash in oil prices, the sorce of income dried up and revealed huge flaws in the country's infrastructure and government inefficiency and corruption.

It might help to read a bit more closely. A lot of the optimisations being discussed were already added years ago; the point is that they are not as useful in real-world usage as they are in benchmarks (or, in fact, disadvantageous).

JIT compiling a highly dynamic language is quite a different task than AOT compiling a statically typed language. Bit-twiddling tricks are unlikely to be the biggest concern. Try starting with the obvious like https://en.wikipedia.org/wiki/Just-in-time_compilation
I'll play devils advocate here. Their solution is too complex and tries to fix a non-problem.

For someone learning Arabic the letters are the first of many challenging steps. I learned the Arabic letters in 1 day with flashcards. That single day was easy compared with everything that came afterwards. Using a romanized scripts makes all these subsequent steps with grammar and accents much harder.

I can see how this would be helpful in accurately learning new accents, but accents are notoriously inaccurate and flexible, the Arabic letters leave that flexibility, outside of academic text Romanized letters would require so many exceptions that it be like nailing jello to a wall.

It would be useful for news organizations if this system was applied across many languages so that we can always spell and pronounce names correctly.

The use of non-english keyboard letters creates complexity. I much prefer the use of number replacements for letters that teens use when texting. sa7?
I don't find it better than PostgreSQL for most applications but their sales department is much stronger. In the enterprise, many applications are sold specifically to run with the Oracle system. Oracle's other products can be a mish-mash - Peoplesoft is a horrible mess (my favorite line during the sales process was "PeopleCode is a Javascript like language that compiles into COBOL - later we found that the COBOL compiler wasn't included in our quote).

I do need to say that there's a lot of humor available with Oracle - watching Ellison's keynote at Oracle OpenWorld made me think I was hearing about AWS. Every product he talked about was cloud-this and cloud-that. Who knew that every product Oracle ever made was part of the cloud? He also trotted out the idea that you could create applications without developers by demonstrating an application he made himself - I guess he's representative of a typical administrative assistant?
You're making the argument "If I apply good crypto plus crypto which might or might not be good, the worst case scenario is that I end up with crypto which is at least as good as the good crypto."

You're the perfect example of Dunning-Kruger, where your skills at crypto are really bad so lack the knowledge to evaluate your crypto skills. You're exactly the kind of person that advice is aimed at.
Except Hannover Berlin is more or less the same as Paris Lille. Paris Lille is under 1h and the price never exceeds 35 euros (which means you can sometimes find tickets under 20).

Now compare the prices with the price of everything else in France and Germany and you'll see why I say that trains in Germany are terribly overpriced.
Afaik breaking a 128-bit ECC key does not require brute-forcing 2^128 keys but rather computing 1 difficult problem on a 128-bit input.

Breaking e.g. AES key of n bits requires you to try 2^n combinations, but the actual computation per key is very fast.

It's not a "scam". Electricity is fungible, there's no such thing as "dirty" electrons. Everything feeds into the same grid, and the math works out. Germany buys a ton of hydroelectric power from Norway, and generates its own wind and solar. What more do you want, exactly?
