I'm not sure why this software behaves that way -- but it used to be a (mis)feature of measuring typing speed on mechanical typewriters -- there were no do-overs. The only way to correct would be to either go back and strike-through -- or manually correct, whiting out the error, and typing the correct word. The first wasn't really usable for "typed" letters and such -- and either would take much more time than on a word processor. Because of this, when measuring wpm/typing speed, errors are severely punished -- even if many of those can be taken care of with auto-correct and/or much faster manual correction.

I'm not sure sticking to this measure for typing speed now that hardly anyone uses typewriters -- but errors do break flow, and for that reason it is good to train towards perfect typing -- even if that means typing a little "slower".

"Optimisation" may include "throw away the shaders provided by the game and replace them with entirely different ones written by NVIDIA for this specific game".
Ah, yes. Thank you!

Although, that means the 10x setup must cost much more. I think the idea in the comments above was taking 10 cheaper, weaker servers and somehow coming out with roughly the same price...

Well, in any case, things just got too complicated :)

NVIDIA provides restricted source to everything but TXAA, PhysX and beta libraries.[1] I'll re-iterate my point: AMD would have access to the code if they walked in the door.

This happens to an almost comic degree in Boston. One car, invariably with Maine plates, insists on leaving five car lengths between them and the driver in front of them. By Boston standards this is a monster opening which is quickly filled and the Maine driver continues to back off. This happens the entire way through the city.

As a researcher, it's always safer to only test online services that have a bounty program and/or researcher amnesty program in place. By virtue of having those programs, however, those companies are demonstrating a certain level of information security maturity. If your interest is in warning users of risks to their privacy, the greatest risks to it are most often found in companies who haven't quite gotten there yet. By finding the issues and reporting them to the company, they may spur them to improve. If the company is unresponsive, disclosing the issues publicly instead may motivate them to respond. We don't want that response to be a lawsuit or criminal charges when the researcher is performing a public service.

Security researchers try to call attention to security and privacy risks early. They aren't always right, but even when they're wrong, it's still beneficial for the rest of us to have them sounding their warning calls.
Yes, and starting from the distributed version first, one can even miss the fact that everything can be immensely faster once the communication is out of the way.

There's no a single simple answer, except: don't decide about the implementation first, instead competently and without prejudice evaluate your actual possibilities.

Also don't decide the language like "Python" or "Ruby" first. If you expect that the calculations are going to take a month, then code them in Ruby and wait the month for the result, you can miss the fact that you could have had the results in one day by just using another language, most probably without sacrifying the readability of the code much. Only if the task is really CPU-bound, of course.

On another side, if you have a ready solution in Python, and you'd need a month to develop the solution for other language, the first thing you have to consider is how often you plan to repeat the calculations afterwards. Etc.

We can build phones that last us a few days on a charge already. We have all the technology we need. The problem is we (both customers and OEMs):

1) don't really want a slower/more efficient processor (like Cortex A7/A53)

2) don't really want a smaller ~4.5" screen

3) don't really want a 960x540 or 800x480 resolution

If we could build a "premium" phone with those specs (for instance the same resolution, but a much newer and more efficient display technology) we could make them last even more than these low-end phones where we typically find these specs.
I was under the impression that electrons moved at the speed of light, but according to [1], they "only" move at 2200 km/s, which is less than 1% of the speed of light (~300000 km/s).

But my point is that a lot of people who aren't trained graphic designers, know nothing about the history or practice of graphic design, and have probably never studied art are able to produce cool designs that are close to the standard of professional work.

And also that being to do this is a huge personal and business benefit.

Being able to code gives you - what? If you're not doing something useful with code - probably professionally - it's not a communicative, practical skill.

Office, much as I hate it, kind of is.

There may be some intangible benefits. But so far as I know there has been no research to suggest that learning to code improves personal, social, academic, or professional outcomes at school.

Meanwhile there's a lot of research to suggest that learning a musical instrument or a second language has obvious measurable benefits.

Obviously I'm not against coding. But I'm definitely against any mythology of coding that suggests it's a key literacy skill - because based on real evidence, there a lot of other skills with a better claim to that.

This is something I love to think about when driving on the highway. I've read so much on it. I've also had some thoughts on recommendations to solve it

1. Divided lanes for 3+ lane highways. Basically a modified HOV lane but no occupancy restriction. The far left lane would have lane dividers with openings every 5 miles (or 3 exits). The middle lane opening every 2-3 miles (or every other exit). The idea is that it would force a certain average speed of traffic and hopefully distance between cars in the respective lanes.

2. Smart roads to adequately distance cars from each other. Either a driver assistance signal or actually controlling the internal cruise control system.
this reminds me of this quote

"Before I learned the art, a punch was just a punch, and a kick, just a kick.
After I learned the art, a punch was no longer a punch, a kick, no longer a kick.
Now that I understand the art, a punch is just a punch and a kick is just a kick."
-- Bruce Lee
Ironically or without thought might last until the first time the going gets tricky, don't you think?
Yup.

We don't even have "cruise control" that is usable in the wintertime -- but we just placidly believe every yahoo who claims to have solved the problem of completely autonomous driving!

Have we ever heard of Unit Testing? It is unlikely that my 10-line function is 100% correct. But, I just know that any random company's Autonomous Vehicle is certainly able to handle black ice in a white-out. What could possibly go wrong?
Ad 0. I agree. Your article got valid point. I wouldn't do serious research based solely on complicated spreadsheet.

Though in many non-techies things, like daily sales transactions it is a way to go.

Ad 1. pandas/numpy would put it on par with 2.

Ad 2. Would disagree. I know data scientist using Spark. Mostly they like Scala API.

In general, everyone got their favorite weapon of choice and what they feel comfortable. The point is that simpler solutions sometimes are just enough do their job.

I stopped using it about 3 years ago. We got our Wordpress installation hacked every 2 or 3 months. I'm uncertain about their security today, but back then was basically non-existent. Their plugin system is helpful, but it also increases the attack surface of your website.

How do we (and the OEMs) know that there isn't a large enough subset of customers that want these things? I'm guessing many customers would accept a weaker processor and lower-resolution screen in exchange for more battery life if the phone's marketing emphasized the battery life over the processor and screen specs. And while we're at it, why not go all the way to a Cortex A5?

So after giving it some thought and doing some additional research it looks like they are building a superdetailed graph based on your relations, textual content etc. etc., try and determine and geocode locations based on the analyzed data and then plot those locations through Google Maps. It looks like it is even smart enough to go through your followers, determine the kind of relationship you have with that particular person, and if you and the other person are closely related enough pick certain locations up from their timeline and share those locations between your profile and that of the other person (something which supposedly has happened to a friend of mine given the returned data.)

"I know people would would be highly insulted if you called them hourly paid."

On the other hand, there are also high-status professionals, like lawyers, who bill by the hour.

I think one advantage of being paid for every hour of work you do is that whoever is paying you is going to be less likely to burn overtime hours on meaningless things. For example, that arbitrary end-of-month deadline you're working on doesn't look nearly as urgent to the business if they need to pay for the night and weekend hours required to meet it. If the company knows that each of your hours is valuable, they might even treat you with more respect.

No, it's still a thing. The headline conveys the general idea/summary of the article, the first paragraph conveys the most meat, and information gets more and more 'fluffy' from there.

Headlines are carefully crafted to sell papers, but definitely convey a message. So, for example you get (from the NYT today)
"Banks Admit Scheme to Rig Currency Price";
"ISIS Seizes a City Pivotal in Syria and in History";
"Rallying Cry in Anti-Test Movement: 'Opt Out'; and
"Kentucky G.O.P. Left in Disarray by a Close Race."

Instead of:
"You'll never believe what these bankers were caught doing";
"Four things ISIS is famous for";
"Teachers want your kids to skip these tests?!?";
"5 reasons the Kentucky G.O.P is in Disarray".

See the difference?
A Replacement for Quantum-Vulnerable RSA
* Once you create an application, you can set how you want your users to provide their identity. You can ask just for the email, email+digits or just their phone number. However, when you deny a notification from your phone, the user is required to provide the second identifier (email requires additional last 3 digits, phone number also requires email, and email+digits requires the full number in addition)
* The system only allows a single login per user, so if you have initiated the request first, somebody else would have to wait for you to finish the request until they can initiate it). There are additional limitations happening in the background that prevents spammy logins to reach the user's phone.
* We're still trying to improve our UX, so we might take that in consideration for future releases

It seems as though that might have changed[1] (dated 1 year after yours). In truth those in the AAA industry might only be privy to what is actually going on, as I'm seeing a lot of PR bullshit/he-says-she-says from both sides.

I'd like to know as well.

I remember seeing some data about iPhone battery life over the generations. Apple has basically held it steady - as the processors and screens have improved, the power efficiency has improved just enough to hold battery life constant.

The exception to this was the 6+ which due to it's larger size, had a fair bit more battery life.

Personally, I'd love a phone with 6+ battery life or better in the 5S form-factor. I don't need or want a large screen - that's why I have tablets and laptops.
I'm a bit confused, don't the losses of an AC->DC converter go into heat as well? Why is that less efficient than a cheap AC heater? Is the energy lost in some other way or is the heat generated by the converter not usable?
Though to be fair, no larger business would ever pay Dell sticker price. I bet they would sell it to a good client for only 200k ;)

I'm doing the John Hopkins/Coursera "Programming in R"[1] course at the moment.

This course seems to be written for statisticians to learn programming, but as someone going the other way it is painful.

There's an assignment[2], where a function prototype is

makeCacheMatrix <- function(x = matrix()) {}

makeCacheMatrix doesn't make a matrix (it wraps a preexisting matrix in a structure that lets it cache the inverse of the matrix along with it).

While I understand that the problem is a constructed one to teach R scoping, the completely wrong naming of the function makes me wince everytime I see it.

Today I'm working on dataset of 1GB, which fits in memory. But it is not enough. If a variable is category/factor you need to introduce dummy values and your dataset starts picking the weight.

My point that "data in memory" is just the beginning...
yes, currently the app has an optional pin unlock that you can set per profile. However, we're looking to add additional "something you know"'s on the user's part to minimize unauthorized access to the device.
I hope the new low-level API kids on the block, like metal and vulkan, can switch the fight to actually compete in having solid GPU performance, and benefit consumers in the end.

Then, maybe a GPU independent HairThing™/intermediate level toolkits can actually flourish.
I thought that too. My mistake was in confusing the speed of the "wave" or signal (which travels at about 50% to 99% the speed of light) and the speed of the electron, which is quite slow.

I think I'm confused about waves because of early childhood text books that had person A's mouth, then some lines increasing in size (like the lines on WIFI symbols) and then person B's ear. I now think of waves as moving forward, pushing forward, rather than up and down.

Is there a version of "Maths for mums and dads" that covers science?

> Think Fort Knox like. We use the same algorithms approved for top secret information like AES 256, SHA3 and public-private key encryption.

statements like this make me very very nervous as AES by itself is basically useless and the impotent part being how they use AES.
The drift speed of an electron in metal is actually much, much slower, somewhere on the order of millimeters per second. The electromagnetic wave in metal propagates a lot faster, and it's usually pretty close to the speed of light in a vacuum. The link you posted was talking about the speed of an electron in an atom or something.
Wow, why such negativity here? I'd guess it's because it's a rich person saying it, which I get.

Do we really need to cite the benefits of working less?
No, that's exactly what you're trying to accomplish.

You're already got a headway interruption. Both buses are arriving at stops after a longer-than-usual interval. That means there are more passengers waiting.

You've put the empty bus ahead of the full one. It picks up the waiting passengers.

The full bus trails, briefly, it discharges passengers, but loads none (or at worst, a very few).

This continues either to the end of the line (at which point regular headways are once again established), or, possibly, until the lead bus becomes full. At that point, you might swap positions, but only then.

If you were to put the full bus in the lead because it was "getting delayed", you'd only re-create the problem you initially had: of a full bus trying to load and unload passengers, which happens much more slowly than for an empty bus, while the less loaded bus that can accomplish loadings/unloadings faster trails behind.

Your letting the trailing, full bus lead doesn't save time.
