Nitpicking is good, it helps to clarify the conversation.

So my reference to refueling was around the time issue the GP mentioned, typical electric vehicles take a lot of time to transfer the same number of joules of energy that a gasoline car can transfer in a couple of minutes. That said, lets look a bit more at your concern.

You wrote : "only because electric power transmission is a damn-hard problem to solve at a global scale."

You are absolutely correct that a generalized solution for global power distribution of electricity is an unsolved problem. However you must be careful applying the general problem to a more specific case. Car charging has some nice features, one you can start and stop the electricity to it over the course of a charge and it won't notice (it will just take longer), its a constant load vs a varying load. These two aspects of it combine to make some creative solutions possible. One of them is fuel cell recharging.

Fuel cells can generate energy reliably from hydrocarbons but they really don't like rapid changes in load, they are most efficient when they can deliver a steady stream of current. So from an engineering perspective you could build a fuel cell based 'supercharger' type station, where you pour in 10 - 20 gallons of gasoline and plug in. Finesses both the long distance transmission of power and the availability. But its just one of a number of creative ways to fuel cars which want electricity rather than gasoline.

One of my favorite nuclear power 'hacks' was to build a 10GW nuclear plant in the middle of the desert, and next to it build a solar panel plant. Using using power (and heat) from the nuclear plant you melt silicon, refine it into crystals, smelt aluminum and build solar panels which you then truck off to places that need power. You are essentially putting the scary nuclear plant far from humans in a place they don't want to live anyway, and making a way to generate power which you then transport to places where you want power.

If you put enough solar panels in your village in Nairobi to charge up your Tesla truck over the course of a week then once a week used your truck to carry goods from the village into the city, I still think that would be a benefit to the village, but I cannot prove that.
Not exactly what you're looking for, but Mixpanel has something they call Funnel Analysis. If your registration has multiple steps, funnel analysis will tell you where you are losing customers. Mixpanel can tell you that a customer clicked the invite link and then stopped filling out the registration form half way through. It's then your job to figure out why that might happen.
Happens to me all the time, new ideas seem more appealing, perhaps easier to implement, and more profitable. so why not move on ?

That still seems like something of a second order problem in that you're solving your own problem that you might need in order to solve a customer's problem.
The main value to the customer wasn't ftp'ing the files over, it was the technical understanding to find a script of value, make sure it was written properly, documented, etc. Not to mention the time you took to understand their issues.

"Choose Life" for Developers
> A scalable variation of BSD socket API is supported by every major OS with a sole exception of Windows

It's funny, you mention "epoll, signalfd, timerfd" as an example of a portable API, and then when I point out they're Linux APIs, you suddenly start talking about "a scalable variation" of the BSD sockets API. As for your "scalable variation of BSD sockets API", why don't you tell us the name so we know what you're referring to? Are you talking about Kqueue for example, or something else?

> an abstraction that is both simpler

I/O completion ports are just read-write queues... you ReadFile(), and when it's done, an item goes into the queue.
(You can insert your own tasks into the queue, too, if you want.) Now just pop off the next item in the queue and off goes your thread. What part of that was so complex compared to your portable API (which for some reason you didn't feel was appropriate to mention the name of)?

> and more universal

Can't reply to it without knowing what "scalable variation" you're referring to, and why you didn't actually mention it as an example of portability when you were actually talking about the subject. Is portability actually a concern for you or no? (If it is, why did you bring up non-portable examples?!)
I think it would be reasonable to start requiring a compositor for transparency, if it simplifies the code.

That way we can have our cake and eat it - most of the time if you don't have a compositor then transparency doesn't make sense anyway (performance is terrible) - instances include VNC.

I'd certainly be happy with this solution.

(Speaking as a transparent gnome terminal user).
Attacking The Job Creator Myth
I just tried fish and after half a minute declared it too slow: it is slow to complete (and not very good) and slow to print (or maybe slow to glob: "ls " takes far more time in fish than in bash or zsh).

I do not know if it has all I love in zsh (things like (.) or (om^/) or * or !$), but I would not trade zsh's completion for gaining 10% on startup time.
Good point and a funny post. Although what he sees as fart apps are now "startups" that were not built but "founded" by "founders" causing major "disruption" to all billion dollar industries, unless they are addressing some multi- million dollar "niche".

It's great that people started to ask this question. In past this type of projects were entertained as a hobby, hopefully making a little impact or improving a programming skill.

I hope we get back to basics soon and bloggers will stop promoting entrepreneurs who are just looking for a lottery ticket to next instagram, but entrepreneurs who build reasonable and durable businesses.

I don't think commercial vs. open source really affects that much - regardless of open-source-ness, different projects are run in different ways. Just to give two examples, surely Office's switch to the Ribbon (and putting Office Apps online) was more speculative (or disruptive, or innovative, or whatever you want to call it) than anything being done by the open source office suites. Likewise, Visual Studio 2010 represented a big break from the past with a switch to many managed APIs driving their extensibility story (including the move to WPF for their UI), which was a huge change from their existing COM APIs.

Not all commercial projects are run like Windows, and it seems to me that most of their conservatism doesn't come from lazy or shoddy or shortsighted developers and managers, but rather their large number of hardware and software partners who take dependencies on undocumented implementation details (see Raymond Chen's blog for a virtually infinite supply of such anecdotes).
Nice, I use Tomboy too and just sync the data directory to SpiderOak, but that doesn't help with Android. Will check this out, thanks.
I should not have to dig around the FAQ to find out it costs $12k, that's a large sum of money to consider spending before jumping into the class. It should, at the very very least be on the application, if not on the front page.

I've given Gnome 3 a fair shot despite the fail whale cries from community at large, but after a couple of months it's really starting to wear on me, particularly drag & drop support, which is straight up GONE, system-wide, ouch.

On the plus side, Nautilus has become pointless as I've switched to Midnight Commander, a great FM.

I do have background transparency set for gnome terminal, a nice touch, I quite like it.

Currently hiding Gnome behind I3 WM, but it does creep up to the surface at times, like the odd mid-beer bomit (burp -vomit).

Oh well, nothing is perfect on Linux, there must be some pain involved; otherwise it would be OSX where pain is replaced with happy spinning beach balls ;-)
JavaScript as a compilation target - Making it fast
I disagree. By allowing people to use the word depression to mean "sad" or "upset" or "pissed" or "bored," or whatever word they replace it with, we are doing those with depression more harm.

If someone says they are depressed, we should tell them they need to get diagnosed. Treating it less than it is, I think, does more harm.

> I should really have looked for help a lot sooner.

But you didn't, precisely because people use the word far too lightly far too often.
Tesla's market cap is currently one and a half times Fiat's. I know it's a rough measure, but that seems a bit excessive.
Then the problem lies with programs that do understand animated GIFs, and not those that don't!

If the GIF software can navigate multiple frames, then it must know how to render them. Its only lazy programs that would export these incomplete frames by just copying the bitstream. A properly written program would export a full frame, made from the composites of the previous parts of the animation.

The programs that are viewing these single frame exports are rendering them just fine, they were simply supplied with poor data.
More trips to the gas station means more fuel burned going to the gas station. Do you have evidence that the savings from carrying less weight outweighs this?

As a programmer I think that well-written code can be beautiful. A pithy, innovative Python script should be worth more than, say, a script that powers a run-of-the-mill to-do list app.

At the same time, I think it's understandable that users and investors don't evaluate startups the way I do, using a programmer's mindset. They're more interested in how well the overall idea has been executed from design, marketing and user experience standpoints.
Very interesting background and well written. My own schooling was more straightforward. I went through K-12 normally in (thankfully good) public schools in NJ and then got my BS in computer science at a relatively normal 4 year university. And I have to agree with you that none of that taught or encouraged self motivation. I always felt like I was just going through the motions to finish school and get to the real world.

Work after college didn't help either. All of the jobs I've had so far (going on 12 years now) have spoon fed me work to do and only my most recent job has given me any flexibility to be creative and solve problems that are beyond the scraps of work they give me.

Getting a taste of building something that I see a need for that wasn't just assigned to me has finally started me towards feeling some motivation to do my own projects on my own time and it feels really good. Over time I hope that I can expand this to my actual job and other parts of my life. I'm just a little sad that its taken me until my mid-30s to get this, so I'm glad to see you've figured it out as early as you have and I hope to help my daughter learn it early on. :)
Well most likely this comment won't be seen by many but still I thought to add my views on what I think can be one way to control depression, specially short term once which we all must have gone through.

1. Most likely life is outpacing "your" speed so lower the speed of life. You don't have to do N things, do N/2 things. It is OK to take breaks and not do anything for few days.

2. Most of the time, depression comes because of disappointment. It is good time to tell yourself that Life is unfair and move on.

3. Do not judge yourself too much, failures are fine. Everyone fails, it is just that they don't talk about it. Despite your failures, most likely, you are still doing better than majority of the people in the world.

4. Talk to people, most of the time, you just want someone around you to talk and may be take care of.

5. Learn new things and Find new hobbies, it often helps cheering you up.

6. Avoid depressing thoughts as they suck you in never ending spiral. Again, talk to people, learn new things and find new hobbies to avoid this loop.

"The author should do more research"

Add: Fawning. This is an article whose intent is to polarize the community of haters and likers by comparing it to Apple.

There is really no comparison. The Tesla isn't a better "car" in the sense of how it gets you between a and b than the existing vehicles out there which are mature products that have been improved over time in the features and benefits that people care about. With Tesla you have to worry about distance, batteries, the high cost - I mean who cares if it accelerates as quickly as it does and who cares that there is no noise?

The potential market for products in the price category that computers are in is much different from cars. Most people don't buy multiple cars and replacing one is a big decision to make. It's not like adding an ipod and an ipad.

Bottom line is what do I get by buying an Electric car exactly even assuming it is the same price as the gas vehicle? How important is the gas savings when you weigh that over the lack of utility in other areas?

I mean get real. Stuff like this will be a non-starter to most people:

"which will give you 150 miles of power in a 30-minute charge"

How many people are going to want to deal with that?

People buy cars on emotion not rationality. It's the same reason someone wants 4 wheel drive even though they might only need it a few days per year.
Wine tasting is not bullshit
Saying wine tasting is bullshit is like saying medicine is bullshit. Pre-20th century medicine was mostly charlatans. Even today the unregulated pseudo-medical market is full of fakes and placebos. But it's a logical fallacy to conclude that ALL medicine is bullshit. The key is staying grounded in a scientific methodology.

This show demonstrates, in a charming affable way, that there is in fact an ability for humans to taste things with specificity.

Great feedback!

We are completely optimized for mobile.

We don't really have a designer on the team, and we all agree the overall design needs some work so design/UI critiques are very, very welcomed.

I don't want to comment on each and every section because I honestly don't have a design bone in my body, but I assure you I will be taking all of your suggestions to the team to see where we can improve.

Love the overlay suggestion. That's pretty awesome.

Suggestions on log-in, signup, info/pricing, nav bar - taken.

Once again, thanks for the advice. This is where we really need some help so it was most appreciated.

or perhaps:

Many people need wine if you want them to work. A windows program on Linux is no exception.

"Test drive one."

But how many people care about how a car drives vs. what they have now?

I own a 911 but I can tell you my mother has no interest and no utility in that car nor does my father. When it just went in for service the dealer gave me a hybrid Cayenne as a loaner. That car has much more utility than the 911. But I have no interest in it at all. Cost of fuel has nothing to do with it either. It's to big (I've had that type of car before when I needed something with that kind of space and it comes in handy).

So my question is, of the things that Tesla is good for NOW (not in 5 or 10 years) what features does it have that the general public cares about that will drive sales? Because I fail to see that the "driving" experience will be one of them. I mean it's not like I get into the Porsche every day when I drive it and say "wow this is so super I'm so happy". After a bit you just get used to it.
They weren't overhyped. Your point is a common and old canard.

The worry wasn't that avian flu or the swine flu would kill a lot of people in their current states, but that they would mutate into something considerably more dangerous. The swine flu, for example, was known to spread easily but wasn't _yet_ very lethal. The avian flu (H5N1) didn't _yet_ spread easily, but was very lethal.

If the swine flu mutated into something more lethal or if the avian flu mutated into something more communicable, then everyone would probably know someone that died from either virus. And that's exactly the worry with these new crop of viruses, and why it's important to react with extraordinarily measures -- to prevent them from becoming something much worse.

That is an excellent question! In the ideal case you would tap into a sub-surface aquifer, in the worst case you would initially import it (creating an artificial sub-surface aquifer :-)) Presumably for safety and economics reasons the system would run closed loop which would minimize losses. The challenge would be heat dump on the turbine supply, however given how cold it gets a night in the desert one might be able to finesse that with surface radiators connected thermally to the reservoirs.

In full disclosure, when the conversation originally came up (when discussing nuclear vs solar a while ago) we just did the basic math/materials analysis and did not do a full operational analysis on the idea.
