I have it in the back of my mind that in fact some of Tesla's Software Engineers are from Apple previously.

A simple Google search isn't returning anything backing that up unfortunately so take it with a grain of salt for now. I think I remember it from a Model S release video I once watched on YouTube which means I can't look it up right now. If I remember when I get home I'll try to dig it up and link it.
I've have great success with something similar to The Pomodoro Technique. Alternating activities every few segments helps me go a lot longer than I would trying to plow through on one subject.

> I wonder what it will be like in a decade or so looking back on the lovely period where only the US Government had lethal drones, and operated them with relative restraint.

You are exactly right. Except of course that the current 'relative restraint' is in the eye of the beholder, and it probably doesn't seem like 'relative restraint' to those living in certain areas of Pakistan.

But yeah, soon enough that'll be all of us. We're in for a world of horror. If we were wise, we'd be establishing the idea that military drones are to be prohibited by international treaty and considered a war crime, not normalizing them.
As these get smaller and smaller, we get closer and closer to a dog pod grid:

Aerostat meant anything that hung in the air. This was an easy trick to pull off
nowadays. Nanotech materials were stronger. Computers were infinitesimal. Power
supplies were much more potent. It was almost difficult not to build things
that were lighter than air. . . .

Given that it was so easy to make things that would float in air, it was not
much of a stretch to add an air turbine. This was nothing more than a small
propeller, or series of them, mounted in a tubular foramen wrought through
the body of the aerostat, drawing in air at one end and forcing it out the other
to generate thrust. A device built with several thrusters pointed along
different axes could remain in one position, or indeed navigate through space.

Each aerostat in the dog pod grid was a mirror-surfaced, aerodynamic teardrop
just wide enough, at its widest part, to have contained a pingpong ball. These
pods were programmed to hang in space in a hexagonal grid pattern, about ten
centimeters apart near the ground (close enough to stop a dog but not a cat,
hence "dog pods") and spaced wider as they got higher. In this fashion a hemi-
spherical dome was limned around the sacrosanct airspace of the New Atlantis
Clave. When wind gusted, the pods all swung into it like weathervanes, and the
grid deformed for a bit as the pods were shoved around; but all of them even-
tually worked their way back into place, swimming upstream like minnows, pro-
pelling the air turbines. The 'bines made a thin hissing noise, like a razor
blade cutting air, that, when multiplied by the number of pods within earshot,
engendered a not altogether cheerful ambience. Enough wrestling with the wind,
and a pod's battery would run down. Then it would swim over and nuzzle its
neighbor. The two would mate in midair, like dragonflies, and the weaker would
take power from the stronger. The system included larger aerostats called nurse
drones that would cruise around dumping large amounts of power into randomly
selected pods all over the grid, which would then distribute it to their neigh-
bors. If a pod thought it was having mechanical trouble, it would send out a
message, and a fresh pod would fly out from the Royal Security installation be-
neath Source Victoria and relieve it so that it could fly home to be decompiled.

Except that now, he's probably a minority shareholder (I think he invested $1bn of his own money, and I saw that MSFT invested $2bn) so if they say jump, he has to ask "how high?" All depends on how the deal was structured, though.

Silver Lake, if they're like other private equity firms, are going to want a 20% return in around 5 years. They're going to put pressure on him to sell the unprofitable parts of the firm.
Depends if your advice is binding. I mean if I call and pay for legal advice, follow that advice and realise I have committed a crime despite being informed that I was on the right side of the law then what have I paid for?
Arguably, licensing that while not licensing look-and-feel elements would be a smart strategy. Licensing the under-the-hood tech gets them money to fund the really expensive and groundbreaking R&D, while keeping the UI out of competitor's hands lets them effectively differentiate.
The rating of individual users sounds interesting, can you comment on that? I would like to rate other forum users, and then find conversations composed of users I like.
This is a myth. Microsoft bought a symbolic amount of stock. At the time Apple had over a billion dollars of cash in the bank. Microsoft was making over $300M a year in revenue from the Office product on the Mac platform, so it was in their best interest to keep up development. The only reason they were going to stop was to strong-arm Apple.

Back then Apple wasn't in great shape, running at a marginal loss or profit, but other companies at the time, like Compaq, were bleeding hundreds of millions of dollars in losses per quarter.
One suggestion to the author of the article. Let the reader decide if Tesla's strategy is ingenious. It may seem like a small thing, but I don't like being told what to think. Make your points and leave it up to the reader.
Web applications are built around the DOM, using onClick methods and many other "web-only" apis. They can not be easily ported without almost a total rewrite, so you may as well use a different language. I also think that recommending a different language is better then recommending javascript, even if that's all the person knows (naturally I'm not suggesting they remove javascript support).
You can abstract the channel operations behind interfaces and regain type safety. Inspired by the sort package, I wrote http://thegoods.biz/broadcast for doing broadcast type patterns safely. To use it you implement two trivial methods on a channel type and away you go, single producer multiple consumer channels.

I think there are clever solutions to these types of problems that have yet to be explored because most of the focus is on what Go lacks from other languages.
Forget about potential speed pitfalls, and consider the following: If your hands leave the sink dry, you no longer need a regularly cleaned tile room to keep things sanitary, because nobody will be dripping/flinging water everywhere. Where might you be able to put sinks now, or how might this change a washroom? That's what is really interesting to me right now.
If such a "solution" involves safely querying, analyzing, storing and manipulating data in any way, SQL and relational databases are usually the best option in practice.

It's much more effective and efficient to use a SQL query than it is to throw together a huge amount of imperative JavaScript code (that's usually very specific to a single NoSQL database, as well) merely to perform the equivalent query.

It's much safer to use a database that offers true support for transactions and constraints, rather than trying to hack together that functionality in some Ruby or PHP data layer code, or relying on some vague promise of "eventual consistency", for instance.

It's much more maintainable, and leads to higher-quality data, to spend some time thinking about a schema, rather than just arbitrarily throwing data into a schema-less system, and then having to deal with the lack of a schema throughout any application code that's ever written.

Aside from an extremely small and limited handful of situations (Google and Facebook, for instance), relational databases are the best tool for the job.

Syncdocs http://syncdocs.com lets you publish a website to Google Drive right from your desktop. It also gives a much shorter goo.gl URL, and automatically re-publishes changes.

However, Google Drive might has usage restrictions, so this is probably only for low traffic sites.
Agree - Daniel Kahneman's Thinking Fast & Slow is a good book that addresses the topic. Understanding how the brain works a bit really helped me to get "in the zone" a lot more often and I have certainly seen gains in focus/concentration (which translates into learning/ability) because of it.
Generally speculation only executes one side of the branch. Speculative threading has been proposed using SMT to execute both sides, but usually you're better off trusting the branch predictor and using threads as non-speculative state.
I guess this answers, "What's he been up to?" Great for him! The need is real. I feel like most discussion boards I'm a part of haven't evolved much relative to the rest of the internet. Even news.ycombinator.com is a case in point.

Cloudflare would never say (and never has said) "meet serverless DNS", because I'm still paying for a DNS server somewhere over at Cloudflare. Sure, it's a different server, but we are still paying (basically the same amount, if not more) for a server.

The title of this post should be "meet a more client heavy version of WebRTC", because that's what it is.

I don't understand the quote "Riskiest of all, it ditched the conventional hydraulic systems used for actuating a plane’s moving parts, and replaced them with electrical controls." This isn't true at all. It has hydraulics and the only difference is one of the lines (center) uses electrical hydraulic pumps. Makes you wonder about the article..
Implications: People are not going to be great at their second job or at night school. It's probably better to quit a tiring job and find a quiet one where you can study something you want to do with your life.
Not sure if that was meant to be a rhetorical question, but here's my opinion:

"Best" posts--those which are a good source of information--have a high view-to-interaction ratio. An inflammatory post on a forum or Reddit tends to see more replies than the average. A good reference piece or poignant story seems more likely to stand on its own--it will have more views than most posts, and have a high view/reply ratio.

What separates a good post from an insignificant one is baseline views. If a thread has been opened 10000 times and everyone has read a certain comment, it's likely to be informative or controversial.

The "best of", even within a single topic/thread, is also per-user and temporal. The best-of in a thread to me is no longer a best-of when I've fully internalized it. I really value Reddit's collapse button/link for this reason.
Here it is, surprised this popped up so late in the piece.

Well if you've used one of their airblade systems you can see that they have a 'down shoot' sort of effect. I've never seen an air-tap so I don't know if they achieve the same result but I suspect that the water uses the same path as the air, and so blowing toward the sink would make the most sense. In that case a poor basin design could get you into trouble with water bouncing back I suppose.
I'm personally very excited to be picking through the ember application(s). It's rather rare to find large-ish open-sourced ember codebases, so I'm pretty stoked about this. Thanks!
Following yesterday's discussion on Ember.js / AngularJS (http://news.ycombinator.com/item?id=5168803) I think this is one more item in the "why to give Ember a try" side (Just for the mere fact that SE chose it over other alternatives, used it and open sourced it, and had you somehow involved I assume). Were you consulting them on Ember development aspects? Were you involved in the development somehow? do they use version 1.0?
obvious question: how is this compared to Redis?

I was optimizing for the total network throughput of the bathroom.

But you didn't. You have serialized access to two resources that were previously independent.

Since a significant portion of users need only one of the two resources you have created a new point of contention. For access to the faucet not only do I have to wait for people washing their hands, now I also have to wait for people drying their hands.

My wife and I have 3 Dyson vacuums. We purchased one and then acquired a couple more over the years. Two are standard room/floor vacuums and another is more like a carpet/floor 'broom'.

They are expensive but all have worked flawlessly. One we've owned for more than 8 years and it's in perfect condition. No bag and it sucks up pet hair like you wouldn't believe. Better than any other vacuum I've ever owned.

As for the Henry vacuums, I'm not sure you'd get the same power for 1/4 the price. There appear to be some models that are that price differential but once you get up to the higher power models it's still cheaper but about 3/4 the price.

Dyson is a lot like Apple. They make dependable, designed products that simply work. You can get by with something else but it will most likely be inferior in form and function.

In another 5 years they'll finally get around to producing a show about Silicon Valley now.

About how the silicon became fabless and offshored. About how Indians took over Koreatown, how all the buildings along the 101 stretch went up then empty.

About how the pioneers settled down while the goldrushers came in wanting a piece in San Francisco even though the 49ers came down to Santa Clara. About how the old campuses went away and got replaced by higher density condos since no one could afford houses.

About how there were the rich and the other half scrambled. About what happens in the middle of the night in those Sunnyvale corporate parks.

About how it's just really bitter and sweet as home.

And to add to your point, since Discourse is taking VC money, it will not supplant phpBB, vBulletin and the likes. Absolutely free software that's been around for more than a decade and web hosts don't have to pay for it either.

As a fellow Cocoa dev, may I ask why you're using PXListView? AppKit has a view-based table view now (since 10.7?) that covers the same feature set.

Moreover, PX has not been maintained since 2011, and there is a bunch of issues and pull requests that are being ignored. There are some forks that fix things, but no canonical one.

PS: Nice app, good work!
Your app may not be intended to replace the website but it doesn't actually work. That's the problem with your app; it isn't functional.
Reminds me of one of my graduate classes, which was about designing distributed operating systems for such things (we used TinyOS: http://en.wikipedia.org/wiki/TinyOS):

Interesting rant, I don't disagree but I see the same forces at work in Dyson that I see in Apple in terms of functional design. And charging a premium for that.

Dyson's biggest contribution to the vacuum market was figuring out how to vacuum without a bag. That was a pretty big deal since vacuum bags were the 'ink cartridges' of the home appliance industry as far as I can tell.

That said, the fake geek speak marketing also rubs me the wrong way.

That will depend on the application in question and how much of the code is directly related to the GUI.

All of the business logic , AJAX requests etc should be fairly reusable.

I know there have been plenty of times building web apps where I have had to maintain separate front-end and back-end code in different languages that does exactly the same thing.

Time can also be a factor, if you are already maintaining a web client , a mac client in obj-C and possibly an android Java client having to learn yet another language and ecosystem is probably not what you want.
You could probably leave the copper coils on the ground somehow, which then I guess would be just like a power plug :)
Think about where the term literally stems from. A smoking gun may tell who did something and what he did. I have trouble imagining a gun (smoking or not) explain why he did it.
Rebranding could be considered a feature depending on your point of view. Most phpBB hosts don't seem to screw with it too bad apart from maybe inserting a few ads.

Yup, for values of "close" that are 3.5 minutes away, which seems pretty far considering how fast those things seem to move. I imagine the real limit will be radio range (you might be able to use some inertial guidance to get the device back into the general area to be able to pick up the IR beacon).
Ask PG: How do you find personal fulfillment by helping startups?
Sincere question, no troll here. I love the tech/startup scene and struggle with this all the time.

As someone who obviously doesn't think there's any afterlife, why are you spending a defining part of your career helping create (even) more startups?

I'm assuming it's not for the money so you must get plenty of personal satisfaction out of it. But it's one of those "is this the absolute best problem I could spending my time on?"
Good point. I was thinking of lacking functions within scripts, which is quite annoying for small projects, but not a major problem for larger things.
Speculation down both sides is independent of SMT and if I remember correct there were proposals to do this - especially where the branch predictor "knew" it wasn't doing a good job on a branch (no point going down both sides of a 99.9% predicted branch).

The problem is that you rapidly run out of execution resources (what if there are more branches to follow, for example) and you will burn lots of energy executing things that don't happen (not to mention speculatively loading things that aren't needed, etc). I remember seeing some papers on the limits of ILP and I think this was one of the 'extreme' ideas (speculation down multiple paths).
This is well documented and doesn't happen with good web practices. If you accept and trust user input, you fail.

Summary of the exploit: If you accept a username from a browser that is (artificially, maliciously) submitted in a typed fashion (as a number or bool), and accept it as such, implicit conversion kicks in.

Both Rails and MySQL perform implicit conversion, so if you sanity check your apps to make sure the string you get from your browser or web service is in fact a string, there is no problem.

Or do you trust your web users?
Expect Labs Partners With Factual To Grow Its Anticipatory Computing Engine
Well, that should be fixable - if this is an actual DMCA takedown (instead of a simple complaint), then it does come with a mandatory requirement to be 'under penalty of perjury'. Intentional misuse can thus be persecuted, and may get even criminal penalties.

Of course, it's a big question whether they will try to fight it in courts and if DMCA perjury jurisdiction can effectively reach the accused company in India.
It is the complete episode?
I'll be the first to agree Dyson is somewhat overpriced but I don't think their products warrant this level of animosity. Those vacuums may be expensive, but they work very well. I've not encountered this "Henry" unit but I've used Miele and Nilfisk and now just use a Dyson. If it breaks in 6 months get a warranty replacement.

And I agree $400 for a fan is ridiculous but what is the alternative? I admit I've got a couple of those fans and I would have liked not to pay that much but it was that or a $15 chinese piece of junk, or a gigantic industrial looking chrome thing.

Show me a company making well designed, innovative high tech domestic electrical equipment and selling them at reasonable prices and I'm sold. Until then, we have Dyson.
Kind of like when Mitsubishi first came out with the jet towel years ahead of Dyson's "airblade"?

There's one piece that's missing: production support.

Now Tesla is entering a phase where they will have perhaps tens of thousands of heavy, battery-powered pieces of transportation hardware deployed, and user support might be a bitch. Nobody's done this before. Ever.

Don't get me wrong. They have done a tremendously fine job so far, but they are nowhere near out of the woods yet, as I'm sure Musk knows. Here's wishing them the best of luck through the hump over the next five years or so.

(Interesting how with startups you do one impossible thing only to be given another, and another. Each time it's like "And now comes the really tough part...")
I don't know about writers and the morning, but there is plenty of evidence that the ideal block of learning or studying is pretty small. For example, you have spaced repetition ( http://www.gwern.net/Spaced%20repetition ), where a few short minutes of studying spread out over time is vastly more efficient than a few big blocks of studying with no subsequent review sessions. And I believe there's a bunch of research on lectures becoming a waste of time after around 15-20 minutes (IIRC, FAA-sponsored).
