Malcolm specifically said that "it takes 10000 hours of deliberate practice to achieve mastery."

There are two component here: 1) 10000 hours and 2) deliberate practice.

What op present us are "you can ditch 10000 hours because deliberate practice is enough" but when you go through the article it shows that all test subject were trained for very narrow set of mastery for short time period (bean bag tossing, microsurgey) or very wide set of mastery for long period of time (football play)
Scattered, a world without paper
I was thinking about this, was wondering if "ToastMasters" style talks would work (http://www.toastmastersclubs.org/welcome/). I wonder if it would be possible to teach each other Tech stuff and use some of the methods that ToastMasters use. The format used is encouragement and improvements. First someone presents something and then someone else encourages the presenter and offers suggestions for improvement. People learn from each other and encourage each other.

Vox.com was banned 4 years ago. I unbanned it yesterday (I think) when someone told me it's Ezra Klein's and Matt Yglesias' new thing. Hopefully it won't be the source of too many off-topic articles here.

Register.co.uk isn't banned, but it's penalized as a lightweight site for having been the source of countless fluff, linkbait, and trollery over the years.

One idea I saw posted last week that I'm scoping out and considering working on: Dataclips for everyone.

Heroku Dataclips allow you to share the results of a SQL query against your database with a simple URL. It'd be really cool as a standalone service that you could hook up to your non-Heroku DBs (local, QA, production, etc). An API would be sweet as well (imagine having a dataclip with your stack traces during QA).
Systems Programming at Twitter (2012)
The QuickCheck model is at least as good as unit tests and is more likely to actually find bugs and corner cases. The resulting code is no more complex either. The only drawback I see is that it requires you to design your code in a very modular way that makes things amenable to automated input generation.

I know RNG's can be vulnerable to hardware backdoors or backdoor-like weaknesses of some kind, but are hardware AES implementations vulnerable to that, too?
Once you stop programming, your skills will degrade like a musician who stops practicing, you'll eventually forget what its like to be a programmer like a parent forgets what its like to be a teenager. You'll lose your ability to connect with programmers, but hopefully by that time you are managing managers who manage programmers, or something like that.

Google can't fill these information gaps, and any manager who trusts Google over their engineers is probably a toxic one at that.
Just curious but where did you see this? This was posted last week on /r/php and the Laravel creator stepped in and pointed out that it was patched awhile ago.
You're still hoping for no bugs and only considering the case of crypto. Maybe there are other interesting secrets recoverable with techniques like these from software written without such cares.

Edit: I wonder if similar timing attacks can be used against the VMs of scripting languages to recover code. It would be a neat hack.

This title is better but still makes the error of assuming the linked story relates to nuclear waste. It doesn't, but instead compares the environmental radioactivity surrounding both types of power plants.
Why didn't I see this when it was posted? How can this post have only 1 point, when the previous one had more than 300?! I would have thought that this would have been in the front page for a while, since so many people liked the idea (me included). I am not an expert in this field, so I don't think I can help a lot, but I support this and hope, that we could see this someday in the future.

Yes. That was the guide, along with the pointer semantics table, that basically convinced me to give Rust a second chance, since if pointers could be summed up in a table, they were definitely comprehensible even for a PL peon like me.
It can still be useful documentation. Four years later and after a couple rounds of heavy refactoring, it's nice to verify that 2+2 still equals 4.
Landing is also a way less serious range safety concern than taking off because the rocket is essentially empty of fuel, rather than full of fuel.
Stanford Encyclopedia of Philosophy (SEP) is an immensely useful resource with a great deal of authority behind it. I used it all the time in college and grad school to get a quick, general understanding of any new philosophical topic that I came across.

Just like Wikipedia, everything is properly cited and you will find all the primary sources in the Bibliography. Unlike Wikipedia, SEP is carefully curated by professionals, but I think it's an excellent example of professional curation done right. Despite the fact that most articles are written by people who are known to have strong opinions on the topics they write about, the articles themselves are generally neutral and contain pro and con arguments for various points of view. Because philosophical theories are often highly controversial and there aren't many concrete facts that everyone can agree on, Wikipedia's model is probably not appropriate here.

"Philosophy of Computer Science", however, is a relatively new addition to SEP, and the low maturity of the field is easily noticeable. Too many topics are squeezed into the same article (instead of being separated into their own articles), and despite the author's effort to include diverse sources, it's clear that not many people are making direct contributions to this field. But I expect this to get better over time. SEP articles are frequently updated, although not as often as Wikipedia. After a couple of major revisions, the article will probably look much better than it already is.

Since computer science is very closely related to various other topics in the logic and epistemology sections of SEP, I would also like to see more cross-references... But it seems that SEP editors are less enthusiastic about linking between articles than Wikipedia editors are. Most links are lumped together in the "Related Entries" section at the end. After all, these people are used to writing textbooks, not online encyclopedias.
You And I – One Direction (Hipster Nerds Cover)
or VBScript for that matter.. I think there's some confusion about why JS won. JS couldn't easily manipulate the DOM either until JQuery in 2005-2006.

The fact that Java, ActiveX etc.. had full control of the system and causes problems ensuring security was an issue, but it is not the reason why JS beat them all.

Don't discount the power of 1) free and 2) easy to use software that is 3) not controlled by a single corporation. JS is the only web programming language that is all of these.

Yea, maybe Python or Clojure in the browser would be cool. I would argue Clojure is absolutely more difficult for a novice to learn, and Python provides what additional benefit? JS was there first.

The only reasons why plugins existed is you couldn't do these kinds of things in the DOM. JQ, and the subsequent advances in browser technology, HTML, CSS, JS - made it so you can. Also, other things being equal - programmers will choose elegance over bloat, less layers of abstraction over more. Plugin architecture became just an unnecessary layer between the programmer and the browser, after HTML/JS/CSS caught up.

JS did not become ubiquitous by accident, or because it was the only choice. There were many choices (all being pimped by big well-funded companies). JS won because it was the better than the alternatives.

Many variables share this exact graph shape over the 1960-2000 period, without having anything to do with crime. It's not a particularly characteristic shape. This seems to be a textbook example of "correlation does not imply causation".

If there was causation (due to the neurological effects of long-term lead exposure during childhood years), then you would observe delayed correlation (at a 20 year scale), not simultaneous correlation.

Compared to the state of "Linux on the desktop" when I first used it, it is absolutely amazing -- no more manually configuring my NICs using jumpers, no more writing a PPP config file (and chat script!) by hand (from scratch), no more running out to buy a different video card because mine isn't supported.

It's not perfect by any means but it is certainly usable by a majority of the population.

How would you feel if, upon asking for a discount (say, 10% off a $100k contract), I offer to instead raise the base rate just for your contract, so it costs the same in the end, but you can also say you got a discount?

Another reason it's less daunting is that, by the time of the landing burn, there's very little fuel remaining in the rocket. On the way up, the rocket has to have enough fuel to power the 9 first-stage engines for 181 seconds, and the second stage engine for 412 seconds. (As well as fuel for the various return and landing burns.) So it will have over 2000 engine-seconds of fuel.

In the landing burn, it's powering 1 engine for maybe 10 seconds. So that's less than half a percent of the initial fuel mass - something that would make a potential failure a lot less dangerous.
So in summary, if you want your company to be the size (employee wise) of a family, you don't need processes (a written down instruction of how to do something).

If you want your company to be the size of a religion, you do.
Free speech is more than just some amendment to the constitution or some right Americans are guaranteed. It's a much larger concept about allowing people to communicate their opinions and ideas without fear of any punishment, not just legal punishment.

I completely identify with this poster. I inherited an app written in CA Clipper (a language from 1987) It became FoxPro. I had to learn those ancient technologies. Surprisingly, I really enjoyed it. I loved those old terminal/DOS apps. Around 1999, we made the decision to migrate the entire app to Object Pascal/Delphi/Kylix/InterBase/FireBirdSql. It was an incredible effort. I loathed, yet loved it. What I learned during that year STILL comes back from time to time in my current development projects. Kinda makes me feel old! When I started doing C#, I felt quite at home. Apparently, the guy who did Delphi, got hired at Microsoft.
One of the guys who worked with me was an ex-employee of the university we were submitting the proposal to. It's always... fun when procurement divisions are involved. :-)

I changed it to the title of one of the sections. This is a trick we often use when the article title (which is often by a headline writer, not the article author) is linkbait or misleading. Assuming it covers the scope of the article, it's often better.
I wasn't really sure why SpaceX decided to launch when they knew that recovering the first stage would be almost impossible when the waves in the Atlantic were 20' high. I guess recovery of the stage was the tertiary reason for the launch (after the payload for the ISS and for the cubesats), however was it critical to launch at that point or could they have waited a few more days for the weather to improve?

One thought which had occurred to me was maybe they needed to get people working on the upcoming Orbcomm OG2 launch which is currently scheduled for May. When you think about all the time and energy which goes into fabricating the rocket along with all nine Merlin engines, it really hits home how significant of an achievement making reusable rockets will be when SpaceX pulls it off. You have to think that at some point in the not-too-distant future it would be absolutely crazy to launch a rocket where you knew you were going to lose the first stage.

PSR-0 and PSR-4 autoloading of classes in PHP
I think one of the biggest barriers to formal verification is that it is, for lack of a better term, "too formal". There's a bunch of other terminology, language, etc. you have to learn, and the learning curve is steep. For someone who just wants to prove a few pre/post-conditions on some functions (that's why I looked into Coq originally - and gave up because it was too hard), it's too much. There is a feeling that it is too theoretical. I eventually found it easier to prove what I needed to, manually.
The difference is Google mostly works. And yes I hate that Google has lousy support.

AirBNB's corporate culture is based on the idea that nobody will care because the users would do it for free but it is nice to get paid.

When you raise 500M on a 10B valuation, people start to care more that your stuff works. If you get a moldy muffin at a bake sale you say, "no big deal that was a nice guy". If you get a moldy muffin at Starbucks you get a lawyer.

I am now a "Starbucks Franchisee" and so people expect more. I am also betting big on AirBNB with multiple properties, so I need them to do their part.

As to the "dig" that I should be using Hyatt or Doubletree to do this... I expect I will soon. You don't expect them to stay out of the market do you? I expect Expedia to be in the space in the next 3 years as the legality of running a hotel (and that's what I do) gets shaken out in NYC and SF.

Extremely vulnerable I'm sure. It should be trivial for a hardware backdoor to get the key out of the AES-NI instructions and then have some kind of secret instruction to give the key to the attacker. The attacker would just need to spin up a VM on the same CPU and start extracting keys. But if you already don't trust Intel/AMD you're screwed anyway. Hardware backdoors are really scary and unverifiable.
As you can prove to yourself by rereading the parent comment of mine, I have stated not that “good ideas and inspiration are not a product of routine”, but that “good ideas and inspiration do not come up routinely”. To further explain my thoughts, let me add that one need not be inspired or have a good idea to train themselves (training is what the kind of routine we're talking about ultimately is), but need be wishing to train and have some idea, which need not be good.

It is a fine method of developing one's art/science/etc... skills to regularly practise, but not a fine method when it comes to startups and founding companies, think I; for such things happen to have consumers, people who may be favouring the product and incorporating it to their daily lives, which will be disrupted when the founder loses their interest in that product and proceeds to the next month's startup.

They may have had a goal of building 12 web sites in 12 months, or 12 blog posts in 12 days, but this person chose to launch 12 startups each month, and launch those to press. Launching companies regularly is dissimilar to painting regularly. (TBH, I did not double check if this serial founder is referring to some ordinary web application as startup)

Some say it was a decline in environmental lead, as the linked article does. Some say it was the advent of mandatory sentencing and three-strikes laws. Some say it was the easy availability of birth control and abortion, meaning fewer unwanted children were born.

But, social psychologists to the contrary, we will never know, because this kind of study can never ascend to the level of science. All we can be sure of is a rise in ... not crime, but contentless articles whose titles end in a question mark.
I'm not sure I understand. This doesn't appear to be a $200 laser cutter, it's just a $200 laser that can cut through some materials that you strap to the head of an existing CNC machine or 3D printer.
