We are just getting started but we have plans to build an interactive input methods where you can add more details to your apps. We do have plans getting there. We are initially mobile focussed.
Even something as mundane as error correction coding were developed at NASA, for communicating with spacecraft - technology that's now present in e.g. CD/DVDs, and every mobile communication system.

Now, if they hadn't developed it, someone else probably would, but perhaps not at that time - leaving us at years behind where we currently are with e.g. the speeds on our mobile devices.

This is why I've learned to always under promise and (try to) over deliver. Whenever I think a project may take me 4 hours, I tell them 3 days. 1 week = 1 month, and so forth.

Another valuable technique is the Pomodoro one, dividing one's work into intense 25 minute chunks of time. One then starts to think about work in terms of number of Pomodoros, giving oneself better a better idea of quantities of work. There are other productivity and health benefits as well.

I see the issue with a search in the App Store, but I have no clue why this is happening. It shows the name in search suggestions, but when I'm clicking on it, there is no my app in the results. Any idea why?
By measurable, I mean objectively. Mattering "as much as a vote can possibly matter" is not objective. Because in that case, all the ones who did not express their vote also had a decisive (non-)vote. Their (non-)vote made the same difference.

All of this does not make any sense. Voting is by essence a collective action, and can not be divided into individual actions.

Well it can, of course, but is has the same kind of meaning as wondering which of somebody's cells triggered his/her cancer, or what is the responsibility of a given car in a given traffic jam (especially those created by slowing cars on the opposite lane of the one having a real accident).
Wordpress injection vulnerability through comment fields
This argument in this article is mainly based on a naive realloc() that does allocate-copy-free, but on a system with virtual memory the memory allocator should be able to reallocate by modifying page table entries, which is far faster than copying the data around; in the (highly improbable) unfortunate case that there are no contiguous VAs on every reallocation, this method still has to move a quadratic number of PTEs, but for the given example of growing to 1M, assuming 4K pages that's only 256 PTEs in total - and 1 + 2 + 3 + ... 256 is 32896. Assuming each PTE is 4 bytes, that gives 131584 total bytes moved, in the pathologically worse case.

And if you’re lucky the OS’s virtual memory system will do some magic with page tables to make the copying cheap. But still, it’s a lot of churn.

There is no actual copying of data, and as the numbers show, a little over 128K for zero-copy reallocations via VM is still 16x less than the 2M of a doubling, copying buffer.

Thus, a better strategy could be allocate-copy-free with doubling size for small buffers, and resizing in page-sized increments allowing realloc() to do zero-copy via VM for large buffers.

offshot topic, from reading the stats at the end of the article: How are cars with higher city than highway milage not violating conservation of energy?

I've heard the explanation that regenerative braking in city driving recharges the battery, but surely it's still better to not brake at all, right? You must incur some loss recharging the battery from kinetic energy?
What do you mean? The close-up shot at 2:52s is under vacuum. The "fluttering" you see is the elastic wave in the feather caused by the sudden drop in internal tension. The feather is an elastic object (to a first approximation). When the feather is hung, there's internal tension keeping it stationary and giving its shape. When the feather is unhooked, this internal tension doesn't just disappear instantaneously, rather an elastic wave travels through the feather at the speed of sound in the feather. Because the feather is not a perfect elastic medium, the effect you see is a damped harmonic oscillator, but it takes non-zero finite time to dampen sufficiently.

This is true for the big ball too, except that the speed of sound is orders of magnitude faster in it, and the spring constant of the material (steel?) is also many order of magnitude larger than the spring constant of the feather.

The center of mass of both objects falls at the same rate. At t=0, d^2x/dt^2=0 for the points closer to the ground and d^2x/dt^2=2g for the points that were just unhooked. Also see https://www.youtube.com/watch?v=mAA613hqqZ0
There are two rate by options "Top Movies" and "Strictly by rating".

"Top movies" take into account the number of votes and use the same algorithm as IMDB does for their top 250.

"Strictly by rating" does what it says. It sorts movies strictly by rating, and only includes movies that have at least ~8 reviews on RT, ~25000 on IMDB.
Damaging human rights is itself a form of harm that should go on the other side of the scales from fighting "terrorism". Ferguson reminded people that in many places the average person on the street is far, far more likely to be killed by a cop than a "terrorist".

Terrorism and police brutality are both law enforcement problems, and the solution is the same: enforce the existing law, impartially, publicly and universally.

The additional problem of terrorism is trying to fight it in other people's countries, where the enforcement brutality is even more of a problem. If you count the Iraq war as "anti-terrorism", then the effect of US anti-terrorism has been to kill, injure, abuse or displace far more people than Al-Quaida. ISIS are more deadly still, but they should be regarded as a hostile state rather than a terrorist group.
What you may not understand is that because our government and those who control society are significantly more sophisticated than brutish regimes you are most likely thinking of, you don't seem to recognize the ruse and subtle means for propaganda that are used to maintain a certain state, rather than attempt to bruit-force a desirable outcome. We have a long history of brutish and vile actions that led our society to reach the point where a subtle background frequency keeps the system humming. Just because you cannot see something for your inability to step out from the mainstream and get a wider perspective, does not make your attempt at negating valid. It is easy to go with the flow and ride the stream; it is far easier to question yourself and everything you have been taught and think you know. It takes courage and insight not easily gained.

I think the torque output would probably break internal drive train components as soon as you hit the accelerator on a gear type setup (you also cant use the back tires for output, it will flip the car over).

You actually want / need some tire flex to absorb the initial torque. This is especially true with electric motors, where 100% of the torque shows up instantly (gas engines have a torque curve)

Watch a NHRA funny car start in slow motion. The big fat back tires actually wrinkle up into themselves a lot, then spring back out[1].

1. See a doctor who knows the fuck about ADD (probably not your family doctor). Get properly diagnosed. ADD is similar to dozens of other things.

2. If you have it to any significant degree, then you need to understand you are working with a Swiss cheese brain [1], that your brain may be closer to that of someone with brain damage or substance abuse. Therefore until you change the brain chemistry (with medication), you may not see significant changes.

I thought I could manage it with exercise and diet and life strategies, but over 10 years I have learned that is not the case for me. Seeing the brain scans really made this a reality, that I'm not working with a full deck unmedicated. I would not have a great job or a great wife and a great kid if I were not medicated.

I use iTunes as my primary media collection, between iTunes Radio, Movies and TV I buy or rent, and even drop in videos from other sources so that I can AirPlay to my AppleTV. I don't sync my iPhone, but I use Automatic Downloading for music and videos, which is very convenient. This works because I can listen to those songs or watch those movies on my Mac or my iOS devices, so it's worthwhile to have it in my library. That is not the case with iOS apps, which take up space on my SSD and offer no functionality. So yeah, I usually resort to texting myself links to Apps to avoid downloading them from iTunes.
A Tesla S was tested at constant 120 km/h to reach 184 km. An Audi would reach 1000km. How far does a Tesla go at 200km/h? 100km? Less?
> that for vast majority of people it's really not important how a car drives at 120mph+

That's why Tesla increased max speed for the new model to 250 km/h?

> That makes me sad personally, but rationally autobahn driving is not a major component of any discussion.

'Rationally driving' is not a part of any discussion of a car in this class. Nobody needs such environmentally unfriendly cars like a Tesla S or the cars of the German brands...

Lower speeds mean lower air resistance. City fuel economy should be higher than highway if braking energy is recovered at a high enough efficiency.

With the HTML5 player you can double the speed; it's entirely in browser, so you can probably capture the Javascript event and make it go at 5x or 10x or whatever is needed to play at full speed. (It'll be up to you to then dub in Yakety Sax.)

> haha, cue firefox going back to using ridiculous amounts of memory in 5, 4, 3, 2, 1.

I just had to force-kill Firefox (v. 33.0.2, on a OS X v. 10.8.1 with 4GB of memory) when it decided to not respond anymore after I had tried (silly me) to open a 14 MB XML page stored on disk. Looking in the Activity Monitor that XML file caused FF to load one of the CPUs at 100% and to use 1.5GB of memory (for opening a 14MB file, that's two orders of magnitude less, I cannot even understand how this can still happen, in 2014).

Don't get me wrong, I've sticked to using FF for more than 10 years now, but they need to get their s.it together.

Later edit: I also checked in Chrome (v. 38.0.2125.111) and saw the same behavior when trying to open that 14MB XML file. At least in Chrome's case killing the tab was much faster (in FF's case I had to kill the whole window from inside Activity Monitor). I've taken a quick look and found bug reports like this one (for FF: https://bugzilla.mozilla.org/show_bug.cgi?id=291643), opened in 2005 and still not closed, which mentiond something like "it all happens because of XML processing". My stupid question is: why in God's name does a browser need at least two orders of magnitude more memory in order to process XML? Isn't XML just marked-up text? I don't get it. What does the browser need to "process"? This is just stupid.

When is fraud "legitimate"? Legitimate fraud sounds a lot like a contradiction.
Why try and be so clever?

I'd hate to be tracing a problem and find code deep in a lib trying to do that. It's OK-ish to expose such things in explicit API, but then you put the burden of choosing (and updating) such constants on the app developer.

If you're trying to avoid too much slop (up to 50% waste), you could either:

- grow by a smaller factor (1.25x, 1.5x)

- trigger a shrinking realloc when certain usage/stability criteria are met (bonus points for exposing this as explicit API rather than implicit behaviour on access, since that could cause exactly the kind of "weird slowdown" people spend ages trying to find (http://antirez.com/news/84)

Even worrying about slop is probably wrong, since if it's a big alloc wasting space, your VM system will probably not even map any physical RAM until it's used. i.e. there would be literally no downside.

(And as to your specific idea - imagine for a sec that future systems might introduce new ways of restricting memory (e.g. linux cgroups) or adding memory (hot-swap RAM, emulated by VMs?). Then your code would be tuning with the wrong value. Not saying that that is likely, but imho you'd just making things more fragile by trying to embed magic in the code.
Perhaps they can now afford to fix that annoying bug: "Figures are updated every 5 hours, last update was 16:17 hours ago"

True, but they're one of a few investigating new ways of launching rockets without having to go through the thick lower atmosphere and from stationary.

I was very confused here. Western Design Centre, not Western Digital. WDC is still around [1] (or at least the website is up - it was last updated two years ago according to the front page).

For those unaware, the 6502 design was largely the product of two people: Chuck Peddle and Bill Mensch.

Chuck Peddle was an ex-Motorola guy that was on the 6800 team but was dissatisfied that Motorola was unwilling to bet on a much cheaper chip aimed at the mass market (the 6800 was around the $250 level before Peddle left; the 6502 debuted at $25 I believe).

Bill Mench was/is by pretty much all accounts a near super-human layout guy. At this time chips were still laid out without much, if any, computer assistance, and prototype turnaround was slow and expensive, so he was a major asset by cutting the number of prototypes needed (the legend - no idea if it is true - is that he had an amazing run of 9 or so designs that came back working on the first try; far simpler designs than these days of course, but to have any come back working on first try was uncommon).

Jack Tramiel at Commodore (who bought MOS) was always penny pinching, and so Mensch was able to retain rights to produce his own 6502 derivatives, and founded Western Design Centre, and have continued designing and selling related cores ever since.

Every project has 'gotchas'. And I don't mean just every coding project, I mean every project anywhere, ever.

Part of the key of navigating those 'gotchas' is to immediately communicate it to your stakeholders when you run into one.

Sit down and watch HGTV for a an hour or two, and you'll see that carpenters, plumbers, electricians, and HVAC contractors all run into problems -

'Whoops, this wall is load bearing, we'll need a beam here and it's going to take us another 3 days to add it.'

'Your main drain is made out of clay, and we'll need to spend 25% of your budget to replace it, looks like you won't be getting that powder room after all'

'The main of your HVAC stack is right where you want to put that doorway, we'll have to spend another $5k on this project to re-route it.'

People that typically finance projects are used to hearing these kinds of problems. Don't assume they won't like hearing them and will fire you - that's a huge mistake. Be honest and upfront with them. Problems like these are not your fault, just be clear on what it's going to take to fix them.
