Understood, but still if XYZ is down at 9AM and you don't need to go there untill 11AM, you're not likely going to check. So then, you go about doing PQR task all morning, to then find out its still F@cked at 11AM. So, the cost is not the 30 seconds to figure it out, but the whole AM you wasted.

Or alternatively, all the time you pre-emtively are checking all over the place at T-1 for using it at T. Depending upon the resolution of this, that can be a PITA and a waste of time. Far more than you skipping over 1/30 of a page on the internet.

Alternatively, there may be some better way to do it. There could be a list/screen for relevance to the community or a seperate page or whatever. But one needs to address or dimensionalize the tension between information flow and efficiency a bit more than your first formulation.

In my local area skateboards are legal on the street except if it has a centre line marker (ie, a white line dividing traffic).

In my opinion, the laws should be uniform regardless of the device (e-bike, e-skateboard, e-whatever). This means restricted to certain types of roads, and possibly allowed on the sidewalk but with speed limits.
> Can someone tell me if it is able to dynamically adapt quality based on available bandwidth?

Depends on what you mean. It is a variable bitrate codec, and the encoder can easily adjust the bitrate of the stream.
But you would need a way to discover the available bandwidth and communicate it to the encoder - Opus is just a codec, not a container or streaming protocol.

> If it loses packets in the stream, do we get a 'skip' in the audio or does the quality go down?

The standard doesn't mandate a specific way to deal with packet loss, but the reference implementation tries to handle this gracefully. [1]

Some properties of the encoding facilitate this: for instance, packets can optionally include a reduced-bitrate encoding of the previous packet to provide redundancy. [2]

Your premise is flawed. Programmer is to user as refrigerator manufacturer is to user. If the fridge fails and your food goes bad, caveat emptor. If you have a problem with that, nobody is stopping you from writing your own code.
Performing Linear Regression Using Ruby
Looks like they're toothed belts, so they should perform OK when wet.

It also looks like they have a belt per wheel, so there's a good deal of redundancy. Because there's apparently no differential gearing it means you have to lift up the outside wheels in tight (e.g. walking speed) turns, but that often happens naturally anyway on a skateboard.

Just kidding.

It's not an argument at all. It's a manner of speech. To be more verbose: I can't think of a compelling reason why you would blindly type whatever instructions you see on the screen, into your terminal. Unless you were being forced.
I saw an invention once which was a foot-operated brake for the back wheels of a long board. I think it had tiny drum brakes for the wheels or something like that. It had a big metal heat soak to absorb the heat from braking. Given I've never seen one, I guess it flopped.
Personally, I think there is room for many more! The ones there are out there are generally way to bloated and weird functional hybrids that doesn’t solve key issues.

I would argue that the ones we have are way too model heavy, and makes all kinds of presumptions what a model is.

I've only been here less than a year so I haven't been exposed to that. What I've observed is that the culture is very compartmentalized in the sense that there are lots of small teams that each have a specific product they work on. Each team basically has it's own culture and way of doing things.

That isn't good for standards/best practices, but it does mean that teams have a lot of leeway to do things pretty much however they want. My team has a ton of flexibility on how we code, test, and deploy, though we have to work within some red tape imposed by other teams that have their own way of doing their things.

In my day to day work I'm actually pretty free to work how I want without being pushed by people up the food chain. That could be because the product I work on is a supplementary product and not a 'core' product, though.

A large avalanche in Montroc, France, in 1999, 300,000 cubic metres of snow slid on a 30° slope, achieving a speed of 100 km/h (60 mph). It killed 12 people in their chalets under 100,000 tons of snow, 5 meters (15 ft) deep. The mayor of Chamonix was convicted of second-degree murder for not evacuating the area, but received a suspended sentence.

TL;DR: Avalanche Risk? = Don't skate !

Fanmail is a part of being a celebrity, and managing your fans is what keeps them happy and giving you money in innumerate ways.

Asking your most fanatic to pay you more money just to email you would be insulting and might trigger backlash.

Since the motors are engaged full time (no freewheel) and are self-exciting, they're going to give some drag due to iron losses, which is magnified by the gearing of the belts, as well as some stored angular momentum.

I intentionally avoided terms like "middle class" because they are so misused in the U.S. It has a specific sociological meaning and, sadly, only about 10-20 percent of Americans are actually in the middle class. Upper class means that you have enough social connections, resources and influence that you don't need to work. Middle class means you have enough resources and contacts to secure steady, well-paid work. (That doesn't describe many people, but it is what the professions used to be like.) Lower class means you are exposed to the volatility of the labor market; if it doesn't need you, you're fried. Under-class means you are outside the mainstream labor market and can't get in.

I'd map those like this:

E1 = Global "Power Elite". One must continually fight for power to stay a part of it; this is *not* a purely hereditary class-- access is limited through heredity, but even lucky-born slackers fall to E2 and E3.
E2 = Upper class. Mostly hereditary. More humble and decent than E1 because the 1930s-60s taught their "robber baron" forebears a lesson.
E3+G1 = "Working rich" or, if you like, the top end of the upper-middle class.
E4+G2 = Upper-middle class.
G3+L1 = Middle class. This level is still way above median, by the way. Again, average is not "middle class". Would that it were.
G4+L2 = Lower-middle class. Fussell called this class "high prole".
L3 = Working class, "blue collar".
L4 = Working poor.
U = Destitute, plus the generational poor.

There is no Fussellian "Category X" on this linearization, but that would probably be mapped to G1/G2+.

One thing that is interesting is how alike the top and bottom are in certain cultural aspects (such as treatment of women). The very high and very low seem to be alike in some ways, perhaps because money, commerce, and aggressive masculinity dominate the lives of people in both otherwise opposite categories.

"It's not really that HTML5 requires extra work, it's that it lets you get away with not putting in extra work and then the lack of that work ends up biting you in the end."

I have never experienced such hard-torque spin in my life. It's not that you would need to put in overtime if you worked here. It's just that we really let you get away with never putting in overtime, if you don't want to. And then that lack of overtime ends up biting you in the end.
I dont know for sure, but I dont think games like Fez, Super Meat Boy or Braid used Unity at all. I think they must be mostly OpenGL?

This brings up an interesting point though. For those starting a carer in "Indie Gaming" should they migrate to Unity or it they can learn OpenGL they should do that?

Unity comes with a hefty price tag though, I think $1500.
Social Media Can Save Lives

Populations under natural selection grow exponentially in the presence of sufficient food. If we have 100,000 times more food capacity than we need, and the population doubling time is a very slow 100 years, then we hit the Malthusian limit in 1,700 years. Exponential growth is a powerful process.

This is the reason so many science fiction stories are set on a future Earth that is baking hot (industrial waste heat) and has fertility police that terminate unlicensed pregnancies. It's a simple extrapolation of current conditions.
From what I can tell, this wouldn't help me one bit. I'm an American who would love the opportunity to found a startup in Canada. That means being there from conception to MVP. But it sounds like this plan will only allow a pretty advanced company, one that has gained the interest of VCs, to move there. If a company was founded elsewhere and was that far along, why would the team move it to Canada? Furthermore, what of startups that don't require VC money, is it really in Canada's best interest to put out the "Not Welcome" mat for them?
I think the country needs to devise a program that lets the next non-resident Jobs/Woz or Gates/Allen to set up shop in their Canadian garage and get to work without any of this VC-related nonsense here.

I visited these guys a couple weeks ago and played some 7 Wonders with some of them after class. It was a fun group and it was really neat to see how it's run.

I've been working pretty hard in improving my skills on my own via Coursera, Code School, etc... but this is way better. Pair programming and then chatting with all the other pairs working on the same thing looked like it was not only effective, but also motivational. It was a fun group to hang out with, too.

The organizer was even kind enough to share a few tidbits of advice for in in terms of learning materials, etc for me to pursue on my own.

I'm definitely applying for their next batch.
What? I'm about to buy, what problem are you speaking of?
A better summary of the article would be "Canada planning to make it harder for entrepreneurs to immigrate".

Otherwise one could think that progress is being made. Whereas it looks like Canada doesn't even want entrepreneurs; instead it wants "hot" companies to move to Canada (see VC requirement and just 2750 visas/year).
Is the idea of a mobile mechanic new in the US? Lube Mobile [1] has been in Australia for at least 25 years and has spawned a bunch of local copies.

The demand for both Rails and iOS devs in SF is huge, the market is nowhere near saturated. It's really the opposite: as Devbootcamp gains success, the applicant and recruiting company pools grow larger.

We taught Ruby/Rails for the first 3 weeks of the current iOS course; several of our alumni directly speak to their experiences learning Rails in their testimonials. That said, the most important (and hardest) concepts to learn through these programs are the fundamental skills of software development (how to model a real-world problem, how to design a solution, how to debug...). Those core, essential skills are common to both Rails and iOS, as well as any other software development work.

I don't know, but the data is out there. You can buy the complete stock history of the Nasdaq fairly cheaply. If you only want day's end prices it might even be available for free.

A quick search found some links for best performing stocks per year[1][2], which indicates that 10x is rare enough that it only happens once every few years.

Honestly for many cars there's not many jobs that require a lift. Even an engine swap can be done with a crane and some clever-ness/swearing. Granted working on an MR car (or poorly-designed front engine) may require dropping the engine out the bottom, but most cars you can get to most everything without lifting the car up more than a foot or so.
A great way to train yourself for the type of lateral position front/back balance needed for all types of boarding (skate, snow, surf) is the Indoboard.

http://indoboard.com

I'd recommend the longer "Pro" model if you're targeting longboard skateboarding.

It's amazing how much Indoboard helps. It will quickly give you an innate sense for where to position your feet, how far forward or backward to lean, and (for a shortbaord) when you're approaching that "oh shit" threshold where the board will fly out from your feet like a banana.

After that, get a longboard and start slow in as much empty pavement space you can find. Try to always keep your knees bent. Start with kicking in front (i.e. the way you're facing) with your back foot instead of in back with your front foot.

Beware of cracks.. beware of hills- even gradual ones. Mentally prepare yourself for some bloody knees, elbows, and palms. Enjoy- it is a really fun way to get around short distances.

I would expect their own apps to rely on whatever user interface libraries the OS offers in order to remain consistent and seamlessly integrate with the other applications on the machine. I have used Windows (and developed lots of software on it) and it always struck me as odd that some MS applications had bits and pieces of the next release of Windows cooked into its interface. I am used to various UI flavors at the same time and rarely even notice it, but I spend most of my time on Linux and I would never expect Emacs to nicely blend in with the rest of the Unity desktop.

Is it too hard to make an IDE only with the UI elements Windows offers? How much extra effort does it represent to make an application that's different from the vanilla look and feel of the environment?

I don't work for Facebook. I work at a mobile company that does iOS and Android development. I work daily on our Android apps. Here is my experience:

1. The cost of maintaining iOS and Android is something like 1.5x the cost of maintaining just one or the other. Most of the investment is architecture and design. About 50% of the design is portable across iOS and Android.

2. Developing reliable HTML5 that behaves predictably is as expensive as developing for a native platform. You may already have the skills, but that doesn't make it less expensive.

3. Most touch frameworks (jQuery mobile, etc.) get you 85% of the way there and then you're stuck. To get an app that can compete with native in terms of realization of design, you end up with lots of non-framework code.

4. (Android specific) The same fragmentation that hurts native development hurts support for HTML5. The test matrix for HTML5/browser compatibility on Android is almost as daunting as the native support. Different device/os versions have different web cores that have different foibles. Its just as big a grab bag as ever.

5. Multimedia support for these environments is just atrocious. Unless you can proxy/convert all content, all but the most trivial content is inaccessible. You end up calling into other applications on the platforms which can present a much less compelling presentation to the user.

I'm not going to say its impossible. I'm leaving out all the arguments of performance because it just gets to be to specific to the use case. I have not seen a compelling example of a unified mobile & desktop browser code base that would eliminate all mobile maintenance. Besides just having people rip up my points, I'd be interested in hearing what HTML5 components people are finding make these issues manageable.

In the long run, its not black or white. We use HTML5/css/js for some things and native for most things. Its how we keep things moving but I'm sure we'll revisit this over and over to make sure we keep investing in the right platform.
