'C' is perfectly adequate for delivering safe and correct* code. Just because it's possible to have 'C' code that is unsafe is not a blanket indictment of the language. Micheal Barr, the MISRA team, Valgrind all exist to aid and abet delivery of safe and correct systems.

*whatever that means in context...

As we say - "doctor, doctor it hurts when I do that!" "Well, don't do that!"

Tools like this simply automate or add leverage to that process.

And unless there's considerable community support for the use of something like this, it'll remain a smaller thing than raw 'C'. But many embedded projects are small enough that there's little pain in reinventing the wheel.

Neat product and like others have noted here - well done on the marketing. Doing other things while driving is dangerous no doubt, but it is also a very practical reality. Any product that embraces this practicality and tries to maximize eyes on on the road is a good step forward in making driving safer.

A random idea: Adding a camera to this could open up the dashcam market. In Russia for example, dashcams a very common and are a part of the driving culture (See http://en.wikipedia.org/wiki/Dashcam and http://en.wikipedia.org/wiki/Sousveillance).

More external cameras, IR, heat, whatever, looking out at all angles. I'm definitely for it. Not sure why we still have those drag inducing chunks sticking out of our sleek vehicles, the reflective things that can ice over, and that you have to calibrate for each driver, now that tiny cameras and range sensors are cheap and ubiquitous.

You don't need a non-religious example; environmentalism is a religion. Its precepts include that nature is good, that human activity is bad, and that by existing we are "destroying the planet" by taking it further away from some perfect pristine state that it would otherwise be in without our influence. The exact method as to how we are alleged to be "destroying the planet" changes from one generation to another, but it will never change that we are doing so. And so long as we raise children to believe in environmentalism, some of those kids will grow up to be scientists who find ways to cloak their religious views in a thin veneer of science...but that doesn't make them scientific views.
You don't need to, that said, there are a lot of riders that have more bike than they have the skills for. Sometimes I feel like I am in that category.

I just spent a weekend in Whistler at a mountain bike camp where a young lady on a maybe $1400 hard tail bike was rolling the same stuff I was on the rented $5k bike. She grew up riding Vancouver's north shore.

My advice for those looking to buy a bike that aren't already gear heads is:

1) Pick your budget
2) Test ride a bunch of bikes in that budget range
3) Pay attention to how the shop you test ride at is treating you -- you want a shop you are comfortable with

Fit of bike and how it feels to you is probably most important. If the bike you like is at a shop you aren't fond of, you can always use another shop for service.
> Karel Čapek (inventor of word robot)

Funnily enough, his robots were actually androids - biological, rather than mechanical, beings.

He also wrote, in 1922, a pantheistic gem called The Absolute at Large: mankind finds out how to get energy from matter annihilation. But that frees up "the absolute", which inspires religious devotion ...

(Pierre Boule, in "Les jeux de l'esprit", probably wrote up the opposite premise, general triumph of rationalism, with pretty much the same result, general conflict.)
It's just determined by the title, so there's nothing else to do.

There are two options on the extremes

1. Keep the HUD in focus and the road out of focus. Your eyes are still seeing a lot of road information that doesn't necessarily need the high fidelity. This is relatively safer than looking away entirely. The human brain can do a lot with scarce information.

2. Keep the road in focus and the HUD out of focus. For things like navigation this will still work fairly well since all you usually need for the navigation is the shape of the road, the direction you'll need to turn in, and how many blocks (roughly) you have until the destination. This is relatively safer than looking away at your phone or gps from time to time, or even looking around for the street names.

Realistically, people will switch between the two extremes.

As I mentioned in another comment, ironworking requires taking things to the next level in a pretty serious way if you want to cast it. Iron melts at 2800 degrees, you need ceramic crucibles, it is heavy, and so on. I'm not going to even consider iron until I have a lot more experience working with aluminum.

That said, I do have some friends who are experts at working iron, so if I do decide to take it up, I'll have a lot of good advisors.
If it was a site with "heavy write traffic" wouldn't the database already be stale anyway while the dump was being taken and restored? Zero downtime maybe not so hard. Zero write loss and zero read-only time is harder.
Sent you an email. This could be a lot of fun.
Did you even read the front page? Just scroll down a tiny bit and read:

"Navdy's transparent Head-Up Display (HUD) projects information
as if it's floating six feet in front of you. In the car you already have."

Further down:

"The image is focused into the distance so the road stays in focus while the driver views the information presented by Navdy. The same technology is used in all commercial airplanes so the pilot can keep their eyes on the runway while landing the airplane."
Many parts of machine tools like lathes need to be as flat as possible, because if the surface of the tool is not flat then that error is transferred to the object you are tooling. To get, say, a lathe bed flat, you buy or make a reference flat surface, paint the lathe bed blue, and then rub the surfaces together. The parts where the blue rubs off are the high parts. You take a scraper -- basically a modified chisel that takes off a thin layer of metal -- and scrape down the high parts. Wipe off the paint, repeat until there are no more high spots. It is very tedious.

It's hard to say why certain types of activities take off.

Inline skating (aka Rollerblading) came out of nowhere to become a very popular activity by the late 80s or thereabouts. (It predates that but that was around the time it really took off in the US.) Today, my observation in at least the places I live and visit is that it's essentially gone away--in spite of the increased availability of paved rail trails and the like.

Recreational kayaks have replaced canoes to a large degree.

Paddleboards are probably the hottest new thing in the watersports arena.

That said, you're right about both the technology aspects and the fact that road cycling was less prevalent and generally more dangerous at the time mountain biking came onto the scene.
"I also don't believe that these mountain bike pioneers were really that pioneering - since the invention of the bicycle people have been cycling off road and enjoying the thrills of descending at speed. It is kind of a natural thing to do. To a certain extent the bikes that came before mountain bikes - BMX - were off-road bikes albeit with small wheels although you could get medium flavour wheels with a BMX."

This.

As someone who grew up in Marin in the 70's I agree completely. When I first saw the title of this post I immediately thought it should be changed to "The Hippie Parents of the Daredevils Who Invented Mountain Biking" <dang, you listening?> IMO, the only reason that mountain biking took off is because our parents saw us hitchhiking up Tam and bombing down on our BMX bikes and wanted to try it out for themselves. Hence, the adaptation of "Klunkers" and "Bombers" that fit their larger body frames. Almost all of these people were, first and foremost, road cyclists.

btw - I first bombed Mt Tam on a BMX bike in 1974.
What is unenforceable about it? Seems enforceable to me. I think they should just make the punishment stiffer.

They're lying to get bonuses/overtime they did not work. The USPTO has a horrible hazard with respect to production quotas, where issuing a patent is less work than examining it, because they'll keep coming back until it costs too much or they get a patent. (I'm oversimplifying things a bit, but you get the idea.)

I don't mind letting them do telework at all. But I don't like paying ridiculous bonuses for unverifiable work.

You couldn't be more wrong. Maybe if you have 4 plugins this is a workable strategy. What if you have 20 or 50. How on earth do you update any of them cleanly?
"These dips could have been caused by a planet orbiting the
binary system, but in 2013, a different group proved that
the third object must be a star. They did this by finding
variations in the orbital period of the binary, variations
caused by the changing light travel time as the binary
orbits a third star."

Translated: the binary star system is co-orbiting a third object, whose pull on the binary is so strong that it must be star-sized rather than planet-sized. How do they measure this pull? It's a Doppler effect -- not the familiar one, a shift in the frequency of waves (like sound) -- but a shift in the frequency of the binary star orbit! This orbit is a clock with a constant 0.258 day period between ticks. When the binary is moving towards earth, these clock ticks are "catching up" [0] with the starlight moving towards earth -- they're compressed together, so the binary looks like it's orbiting faster than it actually is! If you measure this Doppler shift, how it changes as the binary orbits the third star (first moving slightly faster towards earth, then away from it), you can infer the speed of its orbit around the third star -- and from that, the mass of the third star!

I was just reading about this recently: I was going to say (wrongly) this technique was used by in the 17th century to measure the speed of light, by measuring a Doppler shift of the orbital period of Jupiter's moon Io [1]. In fact Ole Rømer measured the phase of Io's orbit, rather than the frequency. You can track Io's orbit phase very exactly by timing the moment it falls behind Jupiter's horizon (a regular eclipse). With Io's orbit as a clock located at Jupiter (the eclipse moment as the "tick"), you can measure differences in light travel time from Jupiter to Earth as they move apart. This is a phase measurement, not frequency; and it depends on the Jupiter-Earth distance, not their relative speed.

Oh look at that, using the term "gamer" to mean anyone that has played a game within a certain time-frame. Sorry, opening up Candy Crush does not make you a gamer.

I don't think it's helpful to call environmentalism a religion. It's a non-objective ideology, and I wish there were a single word for such a thing. Maybe we ought to redefine the word "religion" to mean "non-objective ideology," though. Then we could call it a religion.

Anyway, Robinson was not espousing environmentalism so much as distant-future-generation-ism. That's a distinctive (but equally incorrect) moral position. Not all environmentalists subscribe to the future-generational-imperative, and vice versa.

I actually find the future-generational-imperative to be more widely and uncritically assumed by everyday people, so probably more important to point that out than just plain old environmentalism.

I'm in the 35-44 group and I just continue downward. Salaries post 2k7 haven't recovered, and health care costs in the past couple years have sky rocketed with the new plans. So, with cost of living and property taxes increasing, my pay stagnating to falling when you include health care premiums, I can't even live paycheck to paycheck half the time. The sad thing is I make more in my current developer job of 15 years than if I left to go somewhere else to 2k7 pay levels, so that's not an option.

It's not just a young person thing. It's the new economy with the gap ever widening and I don't see it changing. Just get into the right field. Sales execs making real good money around here (the mid-Atlantic) while IT is not.

You've just described some possible flaws in a p-2-p system. Are there no flaws in the current cab system? Are there no flaws in Uber?

You've pointed out why it can't be perfect. You haven't proven that it can't work.

Perfect is the enemy of good. It doesn't have to be perfect. I was going to say it just has to be better than our current system. But it doesn't. It just has to be legal. Maybe it's better, maybe it's worse. But we're allowed to give it a try (generally speaking -- maybe not in California, but possibly in another state that doesn't have the same rules).

If the flaws you point out occur often enough, then people will stop using it and the experiment will fail.

I would say that's an unfair comparison, as the navdy aims to do much more, for better or worse. That said I had no idea this app existed and it seems perfect as a simple HUD. Given how I use my navigation system, having just the road ahead visualized is all I need.
It is impossible to do dragnet MITM undetected. The probability of a single target validating public keys is low, but if you try MITM`ing every connection, then people will notice the public keys do not match.
When they say the orbital period is 0.258 days, they mean the stars are moving so quickly around each other that it only takes ~6 hours to complete a full orbit? (It may be a little more complicated than that because both stars are moving with respect to a system-wide center of mass.)

I found that a fascinating thought, so I looked up other binary stars and found there's one with a period of ~17 minutes. http://en.wikipedia.org/wiki/Orbital_period#Binary_stars

(Disclaimer: this has nothing to do with special relativity, despite dealing with the speed of light! Delays in observing an event, due to light travel time, are not what relativity is. This is simpler stuff).

"In the first survey (1989), the younger group included families headed by people born after 1954, and so was dominated by baby boomers. The latest group (2013) includes families headed by people born after 1984, and they seem not to have done nearly as well early in their careers."

1989 - 1954 = 35

2013 - 1984 = 29

I'm not particularly surprised that younger-than-29-year olds, on an average, don't earn as much, or are as successful as younger-than-35-year-olds.

The only difference I'd make here is using rsync for the transfer of the dump. If you're migrating a large database, frequently MySQL in my experience, you can run rsync in advance.

With rsync you can cut the downtime between disabling the old-host and promoting the new-host to the time it takes the transfer the changes applied since your previous rsync.

For small hosts/data-sets this might not matter, but for large ones you'll get a real saving.
