Wow, 210 CCA from a LiFePO, I had no idea.

The supercaps provide a huge enhancement in longevity, since the maximum current draw from the battery is lower. This can even mean a difference in manufacturing for the battery in some cases, as there are design tradeoffs between peak current draw and lifetime.

It's also potentially lower weight and lower cost, since you won't need as large of a battery (EDLCs aren't cheap though, so there is a limit).

Yeah, it's really a problem best solved at the car level. Brownout detectors shut off all but the most important systems in the car, and then shut off everything when the battery is reaching critical levels to prevent damage.

Inhale- USC Startup looking to solve indoor/outdoor air pollution
Hey guys would love to hear your feedback on a startup I've been working on called Krafft IT. It is is an environmental tech startup in Los Angeles focused on bringing cleaner air to communities. Our objective is to provide localized data on air quality both indoors and outdoors and allow users to purify the air in their homes,thereby removing harmful toxins and reducing preventable hospital visits while also advocating a healthier lifestyle. We want to integrate air quality as a central
component of the “smarthome” through integration with NEST, Rachio, and other
“smart” products. We want to help people with asthma, respiratory air allergies,
and promote overall awareness about air quality. Our first product which will be
released in our kickstarter campaign in about a couple of weeks is called Inhale. I've included the specifics below. Our website is www.krafftit.com

INHALE- Smartphone Application - ios, android (FREE)
Inhale is a software product that aggregates air quality data from the government (ozone, pm 2.5, pollen) and displays it in a patent protected intuitive way for users to plan outdoor activities based on the air quality in their area. Our algorithm also provides predictions for up to four days to let users to be aware of the air quality and potential for overexposure around them. The final component is the ability for the software tool to measure the total amount of ozone,
pm 2.5, or pollen inhaled through the duration of an outdoor activity by using the pulse meter on a smartwatch o smartphone.
Hi @cpuguy83,

Thanks for your feedback. I couldn't gather enough information for bug reporting (But I had few rich logs that told "docker" has invalid memory access.)

As a work-around, I use a special patch of docker-compose that helps the containers to restart automatically when "docker" daemon restarts :)

> There's also been a known issue around creating lots of `docker exec` instances and those references not being released (so you can query for status later), this is also resolved.

Woh, this seems my case, though I am not sure about "releasing" (We run "exec" and "exit"; we don't hold any "exec" for longer than 2 seconds.) I haven't seen this mentioned in changelog (FIXME). Let me try again in ticket system!
Indeed. I wonder if Ohm works the same way, in that if you have an optimal driving pattern it will last you for 20 years. I suspect based on the Li-ion batteries in laptops and how poorly they last that the Ohm will have a much more predictable failure curve.
We've been asked this a few times, and from everything we've been able to find. DOT approval doesn't apply to starting batteries. There are two different things people generally refer to when they mention. 1) Transporting lithium batteries above a certain size requires an approval. For this one, the battery we use is below the levels they regulate. 2) there are also approvals you have to get for electric vehicle batteries which primarily stipulates a maximum amount of volume of electrolyte that it can spill in the case of it being destroyed in a crash, which doesn't apply to us at all. If we're wrong, and there is some regulation that does apply to us, we'd be more than happy to know about it. Please link me to it.

As far as testing, we've been driving on it ourselves for 5 months now. We have a cycle and temperature testing setup in our shop. We will do all of the testing we need to before we ship to anyone. Our earliest customers are likely to be the people in the world closest to us. We won't give you anything we wouldn't feel comfortable with them using.

Seoul has a pretty fantastic public transit system. Busses and subways come every 5 to 15 minutes, are clean and fast (you better hold on tight!), and are still expanding year after year to the few underserved areas in Seoul and to the cities surrounded Seoul. There are digital signs giving you the time and location of the coming vehicle, and TVs showing news and entertainment segments. Strong cellular service so you're never without a connection. The busses and subways do stop running around midnight to 1AM, but there is always the choice of taking a taxi, which are also plentiful, fast, and cheap (a ride from the south part of Seoul to the north part is only about $10).

3 Stages of a Relationship
> quickly create scalable affordable housing in major cities?

Even in Finland, with relatively good salaries for construction workers, and high quality buildings insulated to withstand Finnish winters, building an apartment building usually costs under 2000€/m2 ($165/sq-ft).

It is not the construction that makes apartments expensive, it is the price of land in a good location.

So the problem is mostly political. Existing residents usually strongly oppose building new homes for new people in their neighborhoods. Especially if you'd like to build higher and denser than the area previously was. And the potential future residents do not have a right to vote, only the existing residents can vote. And even if you can buy a piece of land, city politicians/bureaucrats may not give you permission to build as much square footage as you might want. Because the want to "preserve the character of the neighborhood".

So usually cities do all kind of kicking and screaming to resist growth.
Is the starter even going to crank before the computer is running? Old cars, sure I can see this working.
You could just start the car in neutral, then the clutch engagement zone doesn't matter...
Wanna bet? Health care is more expensive here. Cars are more expensive here (to purchase, but more importantly, to maintain). Food and alcohol are dramatically more expensive here.

In fact, pretty much everything you'll spend money on as a normal adult is more expensive here. I actually can't think of anything that wouldn't be more expensive, unless it's something that's already an obscene luxury good, like a Ferrari.

Your only argument here seems to be that you can make a calculated bet to pay off student loans, because 78% of $130k ($101k) is larger than 88% of 100k ($88k). Maybe, but good luck with that: I think you'll find that the cost of living easily consumes the difference.
Paying engineers more will most likely increase rent prices accordingly. The solution seems to match recruitment objectives with available rooms.
Mine is a little over 30 minutes in good weather[1] (28 miles of mostly highway), Sirius XM and Audible have been great investments. Its about the right length to get the days work sorted out in my mind, but I would live closer if I could.

The reservation suffers from a serious housing shortage never mind not being a member of the local tribe, and eastern ND has a lot of families of folks working in western ND, so housing is a bit hard to find.

Yes, the caps. Classically the reason we use lead-acid in cars is its tremendous power density. Here they are combining LiPo (high energy density) with caps (high power density).

My truck battery pumps out 750CA for short bursts. That's about 12 horsepower. Lithium batteries can only accomplish that in large parallel banks.

The real question is how dev salaries stack up around the rest of the US. Bay Area developers have higher social status than their colleagues in other places, which (admittedly very anecdotally) seems to correlate with better pay.

Are there dev jobs paying, say, $150k in Chicago? If so, I don't see much advertising/discussion for them...
I agree. But "fish" is quite strange to me, especially its way to recall history. In "Bash", I can type "^ R" and browser the history very fast. In "fish", I have to type and select with up/down array; it's not easy to browser the history randomly (FIXME).

My #Bash" history has > 96k entries (woh, believe it or not; because of this too big number, "xterm" + "screen" always stuck when exitting; but "urxvt" + "tmux" work perfectly thanks to "urxvt" daemon mode.)

Porting this huge history database from my daily "bash" to "fish" is just a nightmare ... :D
Ohm can be used for racing, assuming the rules of the race don't require using a stock battery. A lot of our early users and testers actually come from the racing community.
I started to walk to work more than a year ago (5km one way, about 45mins). Makes a world of a difference, as it gives me more or less two hours of exercise per day, time to get my mind on/off of work, call family/friends and other stuff. Bottom line for me - it's less the time spent commuting, than whether you can spend it in a useful way.
$1500 a month isn't "a little better." And Oakland is far from being a cripplingly long way out in the 'burbs.

Plenty of people -- most people? -- in SF have a car too, and no, you don't actually need $500/month for a car. And hey, it's eminently possible to live in Oakland without a car if you really feel that's a priority.

I agree with you: the market is efficient. It's efficient and filled with people who put a big premium on being near the hip areas of SF. If you have less money than those people, you can get more monetarily efficient by being willing to be farther from the hip areas of SF. If you have identical preferences to a bunch of other people making $100,000-$150,000 in an area averse to adding housing density, then... well, you're going to be bidding a lot for a limited supply of housing.
Yeah, that's great, but here in NYC it's either freezing or hazy-humid for 2/3 of the year. Oh yeah, and my commute would be about 2.5 hrs each way, according to Google Maps.

It's not sufficient in Canada. We regularly see temperatures below 30 C. Hopefully they can push it lower, because a battery that quits when it's cold out is pretty much worthless up here.

> (2) Build more housing units in the city. Eliminate zoning restrictions. Stop worrying about protecting the existing homeowners and pay more attention to everyone else.

These three things are not synonymous - or at least, they need not be.

For example, New York is building a lot of units. (A lot of them happen to be luxury units which often sit vacant since they are used purely as investment vehicles by foreign entities, but that's a separate problem.) The real issue is that Manhattan is an island, and there's only so much you can cram into 33 square miles (though they're working on squeezing every last cubic inch out of that). They're also, of course, building at an absolutely unbelievable pace in Brooklyn, Queens, and even the Bronx[0].

San Francisco, on the other hand, has been incredibly slow to build more inventory (and also build upwards), compared to the amount that the demand has increased. This may be partly due to zoning issues, but not entirely, and the situation that San Francisco is in is not typical of most cities.

Houston is famous for having no zoning code, but New York has a very extensive zoning code[1]. In fact, the market for air rights in New York is quite complicated and fascinating[2]. You can build more housing without scaling back zoning restrictions or removing them entirely; there's just not always enough will to do so in every city.

[0] not sure about Staten Island, but... well, let's not talk about that.

Indeed, we've been advocating this approach since Aug 2, 2008. But to be more specific, when PhoneGap was first developed it would load the HTML/CSS/JavaScript from a server just like a chrome-less browser with the url hard coded. Unfortunately Apple started to reject apps that used PhoneGap because they felt it violated this rule which forced us to change how it works to have the web assets already packaged in the application.

We later found out that Apple thought PhoneGap was our own custom version of webkit which is what actually concerned them more. Once they came to learn more about the implementation detail on how PhoneGap works it started to become accepted but this was a very long process.

To clarify, 1) Apple hasn't always approved apps packaged with PhoneGap. 2) PhoneGap hasn't always taken this approach (although this was the initial design).
Its all to do with transportation and nightlife. Bart runs down market street and then south through the mission. A lot of people work near market street. Easy commute. The mission also has a strange mix of gentrification. It has a big mix of locals and new tech workers. With the influx of tech workers there is also a lot of nightlife.

Now if you live in a place like sunset or anywhere in the southern part of the city you are kind of stuck. The southern part of the city you will have to take a bus. The bus can be a terrible experience, if you live on the edges expect a 1hr 1way commute. This is just a rough guideline, not always true. Sure sunset has muni trains but its still slow because the majority of the time muni is above ground on the road and does not have right of way.

I live in outer richmond. I think the pricing data is skewed here due to seacliff.

TLDR; transportation sucks. Most of the areas that look cheap require you to have a car and drive.
Good point. I have a standing desk, so always looking for ways to turn work into some health benefits. Also reminds me of my commute in London via tube from Putney to Canary Wharf which was over an hour each way. I learned two new programming languages while doing that commute.
I'm sure that let him quit his job a whole one year earlier.
(Talking about interactive "fish" shell; but that's the point: I need to be familiar with its interative mode first.)
The article argues for telecommuting to reduce commutes. I think a far less radical approach would be to open multiple offices and put teams in more affordable secondary cities. Modern technology has made it pretty easy to spread your organization across multiple offices. I work at an organization of less than 35 people that has offices in three cities. Outsourcing IT/HR/building administration makes it pretty low-cost to have additional offices, to the point where it might actually be cheaper when you weigh the fixed overhead of each location against the cheaper office space outside NYC/SF.

I live in Baltimore now, and before that in Wilmington, and I'm astonished that more companies don't have offices in those cities. Both cities have a lot less traffic than D.C. and Philadelphia, respectively, and are well-served by rail. I'd imagine there would be a lot of talented people who would sign up at offices in those cities so long as they weren't backoffice locations and they could still do frontline work.
Well, a lot of people / orgs say its important, but dont do it..

>Especially if you'd like to build higher and denser than the area previously was.

because typical "higher and denser" coupled with bottom-line optimization by the developer results in making crappy, less livable environment. More people means need for more transportation, more parks ... - the developer in cooperation with the city could build parks inside/on-top the new high-rise, build new transportation options, etc.., yet it would cut into the bottom-line. Classical tragedy of commons. So existing residents resist more load on the existing commons, yet i think it would be different if new construction was creating more commons and/or really improving existing.

We depend on a huge number of program features so CFG alone isn't enough to throw it off (data references, function layout, linker behavior, and much more are included in our matching).

You're right that, at some point, you've destroyed enough of the features that matching will fail. For that case, you'll always need targeted techniques, such as for virtualizing obfuscators. Since there's a big performance loss when you use them, almost no legitimate mobile apps are willing to pay the battery and speed loss.
Cool. I think it is some kind of special award one can win: being blocked by an authoritarian government. Kudos to Reddit. Long live free speech.
I've never felt uneasy around British police officers. The Metropolitan Police were particularly helpful to me on two occasions. I'm just a somewhat frequent visitor, though. However, the British police have a rather good reputation they mostly live up to in my opinion.

Police in Germany are good as well in that respect. Mostly polite and to the point. Never needlessly aggressive.

I do feel uneasy about the police as a system though and what it's about to become. Home security (or whatever euphemistic term that's called nowadays), politicians and police representatives arguing for ever more surveillance and authoritarian measures. That's what's undermining police work in almost every Western country no matter how good and trustworthy the police in those countries actually might be.
> The way I see it, remote-workers are like work-place superconductivity: Brain power and productivity arrive instantly where they’re needed with zero transmission cost.

I think that's a weak analogy. I think a better one is that you have a core that's off the motherboard but starts up fast. Sure, there's no wake up time, but your communication with the chip is limited by the bus.

We work together to communicate. Being physically remote, even with email, chat, phone, VC, etc. is still lower bandwidth that physical presence. You can certainly make remote work successful, but I think you're lying to yourself if you don't acknowledge that being together in space matters.

This article really isn't an argument for remote work any more than it is an argument for living closer to work.
