OP here; I just thought this was so cool. It's not really about Gulf Racing, its about the 2 colors they chose. Here's an excerpt:

"This phenomenon is called “Equiluminant Colors”. When our eyes encounter colors that are Equiluminant, we have a hard time assigning them positions, so the color tends to vibrate or move slightly. A great example of this is Richard Anusziewicz’s painting “Plus Reversed”. Artists use the technique of “equiluminance” to blur outlines and suggest motion. Because of the way our eyes and brains work, humans cannot perceive the edges of objects where object and background have the same luminance. If parts of a painting are equiluminant, their positions become ambiguous. They may seem to shift position or to float."
> That's because the object pipeline is functionally analogous to function chaining within a single runtime like in Python or Ruby

No it is not. See my response below.
Question for anyone working with CRISPR...

What's the current state of the art for using computers to model or simulate how a gene change will impact the rest of an organism?

Separate but related, if you were to collect data on that sort of thing during an experiment, how would you? I assume there's quite a bit of variation depending on experiment goal... Is imaging technology to the point where you can record what happens as video?
No.

The Fed conducts open market operations, and buys treasury bonds on the open market, directly. Because the goal is to keep the sovereign bond yields low. (To steer investors toward riskier investments with higher returns/yields.) So they basically buy up assets (return producing things) for cash (which loses value with inflation).

They then sit on the assets. (People say it's on their balance sheet, and that's why it's sort of an expansionary monetary policy, because it expands the central bank's balance sheet.) That's why it's not free money to the Government. (Whereas in Venezuela, the Government directly prints money for itself to pay wages and utility bills. Basically seigniorage.)

> My layman's understanding of the situation is that the most likely first use of this in humans will be for personal eugenics of one's offspring. Meaning, removing deleterious genes from, or adding beneficial ones to, your sperm or egg cells in a lab and then implanting an embryo.

My non-layman's prediction is that you are quite incorrect. As others are pointing out, successfully using CRISPER/Cas is hardly as trivial or as easy as the media's hype machine (or university PR offices) would like us to believe. Blatantly obvious ethical issues aside, embryos are hard to tamper with, and the odds of successfully achieving multiple edits to the genome are miniscule.

I think the most likely first application of the CRISPER/Cas system in human medicine will be in an autologous bone marrow transplant to correct a genetic disorder of the blood, likely sickle-cell anemia.

US QE has ended as far as I know. (https://en.wikipedia.org/wiki/Quantitative_easing#US_QE1.2C_...)

The purchased assets (treasury bonds and so on) are idling on the Fed's balance sheet. Eventually as bonds mature the Fed just cancels the newly-created-debt it used to buy the bond, and the asset just disappears from the balance sheet.

"It’s hard to imagine a government that opposes creativity can permanently have the upper hand..."

As a libertarian and privacy advocate, over the past decade or two I've consistently seen folks try to warn the public over surveillance and anonymity problems.

Most of the times, such warnings were laughed at. We got the usual tinfoil hat treatment.

I think the basic problem is this: it is hard to imagine the internet turning out to be the curse it is becoming. After all, as the author noted, we are all free to make our hotel and restaurant reservations.

For as long as I can remember I've had an interest in going to live in another country. But the older I get and the more I get to understand people and the more I travel, the more I start to hold myself back from actually moving to another country. Even if just for a year or two. I think I realise more and more that cultures really are different, vastly more than I once thought. It has me wonder what I would actually end up gaining from such a move, countries with language barriers even more so. Yet, I cannot stop thinking that by NOT doing it, I'm missing out greatly...
>I think most of us understand the historical pressure,

It doesn't look that way from the GP's comment: "I really wish they had found a less confusing way to bolt this move semantics / rvalue references stuff onto C++ ..."

... is actually an example of not understanding (or not being aware of) historical pressure.

If you create a new programming language (e.g. Rust) with a blank slate, you have more flexibility to make semantics "simpler" by rethinking the design of the syntax, the sigils, and the implicit defaults.

Rust syntax accomplishes "move semantics" without double ampersands (&&) sigils and "std::move()".[1] The end result is that Rust syntax looks less cluttered to move ownership around.

The key to Rust's clean syntax is the absence of "historical pressure".

Rust starts from a blank slate without worrying about breaking legacy code. Rust wasn't invented in 1982.

C++ move semantics uses C++1982/C++98 as a starting point and can't use naked variables to let the compiler carry out "moves". Legacy code would be ambiguous and compilation would break. The "rvalues std:move()" was proposed in 2002 and finalized for C++11. They had 9 years for others to challenge Howard's proposal and devise a simpler more elegant way that doesn't break existing code. Nobody came up with an alternative. Hence, the uglier C++ syntax bolted on for "moves" is probably as simple as we're going to get.

Financing is not an answer to this problem.

1. Banks may not choose to finance small businesses at all, because they can finance bigger businesses which are a lower risk.

2. If banks do finance small businesses, they charge them higher interest rates than a larger business, again, because a larger, more established business is lower risk. A small business that has to finance at a higher interest rate will have to make larger gross profits to pay their financing costs.

3. Larger businesses may have enough cash on hand that they don't require financing at all, which makes it even harder for small businesses to compete.

I wasn't ignoring financing when I said that high up-front costs and low long-term costs create the ideal conditions for large businesses to drive out small businesses. Financing simply doesn't solve this problem.
> I've used them for years, though the effect on taste might be a placebo

Personal anecdote that it may not be placebo:

I find the tap water where I live (Northern part of NL) pretty delicious. In fact I can hardly distinguish it from most non-carbonated bottled water, it's just clean with no particular flavour I would recognize (though maybe I'm used to it). When I visited the US (NY and New England area) I found the chlorine taste quite noticeable, also a slight dusty/earthy flavour (I didn't complain, and it was a hot summer).

However, one of the people we were staying with brought one of those plastic jug/caraffes with a built-in filter (probably charcoal), which she filled with tap water. I really didn't expect it to make much of a difference, because how was a tiny filter going to take chlorine molecules (not ions, right?) and that dusty flavour out of the water, that quickly, just by pouring through? (apparently I have no idea how these filters actually work, and a little voice in the back of my head dismissed it as some weird health fad thing)

Well, I was taught :-) I was pleasantly surprised when I found that the filtered water tasted "clean", pretty much just like it tastes back home. But since I really didn't expect it to taste much different than straight out of the tap, actually half-expecting the filter might make it a bit more "stale" (assuming it would mostly take out some of the CO2 and O2 gases), I doubt that could be placebo, wouldn't you agree?

On the other hand, placebo effect can be really weird, in your head, even if you really believe it's not affecting you, so I'm not going to presume there was no placebo going on. I also didn't think to try a double-blind test or something, instead happily enjoying the refreshing filtered water during a hot summer :-)

So, this click bait is kinda outdated, I think.

Furthermore, iirc, Google has a limit of numbers that you can reuse.

As those websites are used by ~100+ people, you can quite imagine that those numbers are flagged very quickly.

Thus, useless.
I'd say that real-time covering hours is less a marketing artifact but part of the academic definition that real-time means that guaranteed timing limits are kept, whatever size they have.
Well, yes and no. The money goes to bondholders, and whoever held the assets the Fed purchased. Basically investors.

The important thing to notice is that this is all a marginal effect. The Fed bought stuff already on the market, so the asset holders already wanted to liquidate those assets, but with the Fed entering the market and driving [bond] prices up (thus keeping [bond] yields down) investors can't just roll over the money, and other investors are discouraged to invest into low-yield assets, thus they try to invest into other stuff, bonds of riskier companies, foreign markets! (The QE programs drove yields down all across the globe, foreign currencies up http://www.bloomberg.com/news/articles/2015-01-23/rupiah-phi... and as a QE program ended this caused problems http://www.reuters.com/article/2013/08/19/us-india-markets-r..., because governments - just like in pre-2008 - saw cheap loans and went to town.)

So, all in all, money goes where the investor things it'll grow best (low righ and high yield). Real estate was that after 2000, nowadays it's all over the place. (RE is picking up again, look at the insane prices in SF and London; VCs pour billions into emerging sectors - look at the valuations here on HN; and naturally people look for riskier things, abroad, which is good for the global economy.)

I think the "untrusted system" in question is the system you're logging on from, because that's the only place where the private key could be compromised. I guess the idea is something like, you have a desperate need to log in to a server but the only computer you have physical access to is a machine you don't control (in an internet cafe, say). So you keep your one-time SSH key on a flash drive, use that key on the untrusted machine to log into your server, and you don't have to worry about the untrusted machine keeping a copy of your key (because that key is no longer valid). On the other hand, you do still have to worry about the untrusted machine injecting malicious commands into your session (including, possibly, malicious commands which would allow the attacker to log in to the server as you again in the future).
Great suggestions for non-technical people in there but if a real concern is ownership and control of content then the only real option is buying or renting server space and putting up a website with maybe Ghost (the most overrated blogging platform ever) or the open source Wordpress or just plain HTML. All the other options listed still could potentially shut you down for some weird TOS violation (like if you're a big KKK supporter or something). Is it likely to happen? No. But isn't this where we post our overanyzed takes on everything?

Why should it be tried first? This kind of experimentation takes decades and meanwhile people are dying.

How many unions do we have to try before we see that they don't really promote progress?

Good question. I've been googling and found nothing.

I think it means that they had regional power grids running with emergency links between them (nearest neighbour basis?) already in case a large part of the generating capacity in one region was lost or in case a site near the boundary of one region became disconnected from that region's main line.

One night they decided to try to activate all the inter-regional links so that power from all the power stations was available across the whole country. I got confused by the 'in parallel' bit, but then you would hardly be connecting them in series!

The grids would have been 3-phase and the frequency was controlled to be near exactly 50 Hz, but then you would have to synchronise the phase of each pair of grids before you made the link active... Any electrical engineers around?

This historical incident would make a good magazine article I think.
Ask HN: Map issues while using Uber
I frequently face problems related to maps while using Uber. http://intosimple.blogspot.in/2015/07/failed-optimization-probably.html describes the problem.

Do you face such problems with Uber ?
Cool! Was he building embedded testers, or commercial testers for semiconductor vendors? I would imagine that a lot has changed since then, especially with the shrinking process size and corresponding increase in retention failures.

In my experience, most of the reputable vendors like Micron, Samsung, and Spansion are pretty up front with how many bad blocks they allow their devices to ship with. The Micron device I've worked with most in designs allows 80 bad blocks per unit at shipment - that's about 2% of total blocks. I've never seen a brand new chip with that many bad blocks straight off the bat. (Two bad blocks in a brand new chip is unusual.)

Most of the big vendors moving to support the ONFI standard has actually had a pretty interesting effect - since NAND is in such demand and has a common interface, it's become pretty commoditized. If you want to sell chips, you have to abide by ONFI. If you do that, and your prices are competitive, your products have been just about guaranteed to sell. As a rule of thumb, however, I would agree with your sentiment. Vendors who won't share raw bit error rates or uncorrectable bit error rates are generally not worth the time of day. That's part of the reason I'm so fond of Micron and have cited them a bunch in these articles - they are very forthcoming with data about how their parts work, and how to put them into systems in such a way that they'll work over your device lifetime.

Sure. But my point was that there are much weaker points than the encryption in a communication system.

I've found that older VHS tapes often suffer from losing the sync signals, making the display shiver and bend. This can be corrected somewhat with a device called a Time Base Corrector.

One can collect the tapes and boxes, but being able to play the tapes is inevitably going away.

If you've got a video projector, watching even a good quality VHS tape that way is just awful (blotchy, fuzzy, smeary).

I'm all for the preservation of history, but I have no desire to handle VHS tapes ever again, and will always prefer higher res formats.
Yes it is, and stop trying to pretend otherwise.

Your long-winded comments about PowerShell's internal language and runtime features are utterly irrelevant since they exist within with PowerShell runtime, just as the features of Ruby, Python, JavaScript, the JVM languages, etc all exist within those runtimes.

You also tried to falsely claim that cmdlets are not instances of .NET classes in a previous discussion (https://news.ycombinator.com/item?id=9461682) and your comments are perfect examples of how PowerShell advocates use long posts of handwaving, obfuscation, and verifiably false claims to try to pretend PowerShell's functionality is different than it actually is.
Weather predictions are not fiction. Some businesses pay millions for a specific weather forecast (one that could dramatically influence the profitability of a venture) in order to enable better planning.
