Thanks! That's interesting too - lifting the public tweet limit would also fundamentally change Twitter. As an author of tweets, I think I'd like it. I think @byuu mentioned it would promote intelligent discourse on important subjects - I agree.

As a reader though, I don't want to lose the high-bandwidth nature of Twitter. The headline thought/status/caption in your stream, with a link to the details hits an information consumption optimum for me.

It's really that first DM in a conversation where I think 140 characters causes me to leave Twitter. Maybe I'm doing it wrong - often trying to stuff salutation + context + question into the first DM. If the convo gets past that, then yeah, 140 is fine.
Hi. I'm the author of the post. The Census report you mention is cited by a lot of other posts out there re work habits. That definitely doesn't make it more credible - just wanted to mention that it's often cited.
They are paying 49 dollars per square foot/year for a fairly cheap (as far as market rates go) 11k sqft office at 564 Pacific.

Rent to Revenue ratios make little sense for growing startups. It will change.
$4k a month is 20% of gross at $250,000 a year. That's acceptable, but not great, and it gets you a modestly nice one-bedroom apartment in a "transitional" neighborhood in SF.

But hey, if your baseline for "fantastic" is the family in NYC that can barely afford housing, then have at it.
I grew up with traditional CI cookware. I know how to season it and how to wash it.

The roommate recently purchased an enameled cast iron skillet. The use and care guide was pretty poorly written. So, a couple of stupid questions on the topic follow:

* The coating inside the pan is enamel, and doesn't need maintenance?

* One needs to not use metal utensils (or steel wool) in order to not damage the coating?

* One can wash the damn thing with soap and water without harming the coating?

Thanks in advance. :D
Median 1BR rent in Oakland is $2000 per month (according to: http://blog.sfgate.com/ontheblock/2015/05/12/what-you-can-ge...). So, look, that's not cheap, but it's $1,500/month less than the median rent in SF that you quoted. The equivalent of an after-tax raise of $18,000 per year.

Yes, it's not in the city. Noted. But, you know, life is full of trade-offs.
It was taken from the Sanskrit meaning for "time". :)
Most of my doctors visits are relatively routine... blood work every 3 months, followups on medications, etc. Killing half a day every other month for that drives me nuts... but that's just me.
(7) This doesn't apply to all performance cars, but in track racing where you really need to save every possible ounce, it's common to take the battery out altogether after starting the car and run it off the alternator.

> Can you start a company outside the valley? Yes. Is it going to make things much more difficult for yourself doing so? Probably.

I would love to see data on this one way or another. I find it very hard to believe that it is quantifiably more difficult to start a company outside of Silicon Valley. But you are not the first person to state that.
right. But it is a nice clean GUI, that handles the 95% percent without any fluff. The git program is very complicated, designed to handle large projects, and it does have a learning curve (especially to keep all the commands straight e.g. git branch -l, git branch -d, git checkout -b, git "reqeust-pull"???). When I was first learning git, I was a little overwhelmed at its variety of commands in the man, and would have preferred this GUI where I'm able to simply click on repos, click to create a branch, and click to create a pull request, to handle 95%+ of use cases. Even hardcore linux users like to use simple GUI tools, sometimes.
Two of these I haven't done: Cherry-picking (well I did once, it went so wrong I had to reset the repository), and Bisects. That sounds very useful.

Indeed, it works as nicely as you'd expect! I have a blog post in the pipeline describing how we do deployments... I need to get that pushed out.
One of the things missing on the map is elevation. FiDi & SOMA are effectively surrounded by Twin Peaks, Russian Hill, Pacific Heights, and Portrero Hill. Those hills contribute to increasing commute times as well as cultural boundaries.
Maybe it's not the whole time commuting, but the time added due to rush hour traffic?
Indeed. In this instance a negative keyword filter would be appropriate. :-)

"Companies" seem like terrible vehicles to work on "projects". Is there a better answer? The dreaded incubator?
Increase supply (e.g., build more housing) or reduce demand (e.g., find a way to make it less important for people who want to work together to live nearby). Those are really the only two choices.
By "the money", I assume you mean "the investors". Most customers are not in the bay area.

Anyway, here's a startup protip: make a business that is growing revenue like crazy, and investors will give you money no matter where your offices are. Move to SF without a business that is growing revenue like crazy, and they probably won't give you money.

...but you'll be able to take a zipcar to Sand Hill Road for the rejection. That's worth something, right?
Of course you won't learn much about a country from reading a single article about it in the relevant section of a weekly newspaper. But if you read it regularly, you'll read numerous articles about that country over the course of a year - probably more than 50 in the case of a moderately powerful and dynamic country like India. Over time you'll realize that some predictions made in the articles pan out, some don't, some is consequential, some not and so on.

Reading a single issue will not make you well-informed; at most it will provide you with something to chat about at a cocktail party (if you're the sort of person who likes to chat about the news) or a point of reference if you meet someone from a foreign country and want to ask a topical question.

I've found that reading over time is advantageous, not because one collects more and more trivia about more and more places (although that's true) but because the more important themes emerge of their own accord most of the time. By this is I mean that one tends to become aware of major issues long before they rise to the top of the 24 hour news cycle.
One challenge in going after the enthusiast market is going to be, the enthusiast market already has options.

Back when I drove a fast sporty little car, I got one of these:

http://www.amazon.com/gp/product/B0002ILK6I

$100, 4 pounds. Proven technology. I can buy it today.

Half the cost, 60% more capacity, and 2/3 the weight of this "Ohm". Smaller too, from the looks of the "Ohm".

I'm not trying to rag on you guys, but I can't figure out why I would pick the "Ohm", unless maybe it's got a really rippin' CCA.

Edit: Amazon is incorrect, ODYSSEY quotes the battery as 15.4lbs:

http://shop.odysseybattery.com/p/pc680-p

To compare like for like, we would look here:

http://shop.odysseybattery.com/p/pc310-p?pp=12

8Ah, 5.9lbs, tiny, $163 on Amazon. I hope you can beat it on CCA.
I would think that most engineers renting 1br apartments are doing so with a significant other. That brings the per-person cost down to $1750, or a minimum of $75k / year.
It's a hard problem, but BART's issues come down to a bunch of fiefdom infighting among different counties.

Paris and London have pretty fantastic transit.
The picture shows 'after inflation', and the rule of thumb is indeed a 4% redraw rate, so the graph seems about right. At 4%, you will keep your capital. At lower rates, you will burn some capital, but not enough to go bankrupt, unless you are really unlucky (last part was also calculated).

So in my opinion, the graph confirms the rule of thumb.
Google was a bad idea because at that time Yahoo, Excite, Lycos and all those "portals" were making money by keeping the traffic on their site instead of sending them away. They didn't even invest much on "search" as we know it because it's better if users generate more pageviews while trying to find something they want. Now google adsense and adwords sound so obvious but nobody knew they would be so powerful. Google was no doubt a cool "project" but no one knew how it would sustain itself (nowadays it's taken for granted you would make money by advertising but back then that was not so obvious probably) Same goes for Facebook. One big distinction between a company and project is company makes money and project doesn't necessarily have to.
it's a lot of risk

What’s a lot of risk? Saving a significant portion of your income? Sounds less risky than “work until I’m 70 and then hope I have a good pension.”
Oh wonderful. Installed it, and now none of the git repos I pointed it to are recognized by git command line anymore :/
"historically illiterate" are pretty strong words. Actually everyone is historically illiterate by these standards because the ideas that any one person is familiar with is a vanishingly small percentage of all the ideas the human race has ever had. Furthermore, the origins of ideas are impossible to trace with any great precision. Is the most famous person the person with the best ideas? Was the person with access to the printing press the person with the best ideas? Frankly it strikes me as a form of intellectual hipsterism to be bothered so much by this.

Rich Hickey gained fame for this because he stated an idea very clearly and compellingly, this is non-trivial and should not be so flippantly dismissed as just recyling old ideas—all your ideas are recycled too.

Looking at some of the negative reviews on Steam, it's not a matter of entitled gamers (and gamers are the most self-entitled demographic in history...). Plenty of the negative reviews I've seen so far are long, and a prime criticism is the 2-hour gameplay time. A few also mention problems with bland gameplay. Everyone agrees that it's beautiful, but it doesn't matter how beautiful your game is if it's short with no replay and the gameplay isn't solid.
I don't know about the three commenters, but I have no connection with Ryan or the company. Very interesting that HN might be worthy of being gamed.

That's why I think everyone should bike to work if possible. It has little to no environmental impact and a positive health impact. And because you are killing two birds with one stone by exercising during your commute, you really aren't wasting any time.

Cities are expensive for a relatively simple reason: the number of people who want to live there exceeds the number of open spots.

Two immediate solutions:

(1) Create compelling reasons for someone to not want to live in this one particular city. For instance, allow one to work remotely. There are hundreds if not thousands of amazing cities to be enjoyed, not to mention the vast stretches of rural land for those who don't want to live in a city at all.

(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.

Note that both of these are mostly matters of just convincing people to jump on board the plan. People in general are resistant to remote work (especially outside the software world, but even inside it), and some cities like San Francisco are extremely hostile towards a vast number of proposals to just build more housing.

When you combine the desire to compress an entire industry into one city with a refusal to build more housing units, what result could you possibly expect?
Yeah, it would be more accurate to say that Ng's course (as best I remember it) provides a good introduction to machine learning and covers unsupervised learning, for which deep learning is one approach.
Do LiFePO4 provide enough cranking amps for a sportbike?
Yes, in two ways. First, it's often useful to target malware or other systems by the common packer code they use. This doesn't require deobfuscating anything.

More interestingly, the matching algorithms we developed are by design resistant to many common obfuscation schemes. For example, Proguard renames variables and functions, as well as discarding dead code. But other aspects of the code that we index, including control flow structures and data references survive. We've designed our matching engine to apply a combination of all these factors to be resilient to changes in subsets of them.

Compilation is one of the simplest forms of "obfuscation", so started with dealing with different levels of optimization discarding code or changing the opcodes.

If a program is self-decrypting, then we have to apply standard unpacking techniques to get back to a reasonable format before ingesting it. Nothing magic there.
So does Austin. Not my particular bit of Austin, but most of it.
The same file system that the Linux developers have tried (and failed) to clone for almost 10 years now? Yeah, must be totally unremarkable.
If you're doing wok cooking, you can get to 900 degrees, although most of us who did not have the gas company adjust the stove for optimal Chinese cooking don't get quite that high. 600 F isn't crazy in wok cooking on a stovetop, though, and Teflon is not guaranteed to retain its properties above 400F. [1,2] Here's a PSA: Teflon-coated woks suck anyway!

Remember that Teflon and related products aren't only for stovetop use. There are many non-stick baking sheets and muffin pans as well, and it's not that unusual to cook muffins, scones, cakes, or pizza (esp pizza [3]) at temperatures above 400. Moreover, using the broiler can quickly get you to a high temperature.

Interestingly, there are a lot of documented cases of bird death in conjunction with Teflon usage [4]. Birds are very sensitive -- hence "canary in coal mine" -- but it is interesting to see that bird death can happen during normal use of Teflon and related products, certainly at temperatures below 400F.

In Camberville, we're increasing supply... of luxury condos. So far, I haven't seen it make a dent in the market. Fort Point in Boston went from having almost no housing to hundreds of new units... yet I called one of the buildings and found their 1BRs to be $3,200/month.

The public transit infrastructure, and road infrastructure, in Boston and SF is insufficient to make living further away ok for most people. But again, that basically just creates neighborhoods of software/biotech people and nothing else, which feels terrible.
We (MSFT/Yammer office) are most definitely NOT in the financial district (god I wish). We're in the tenderloin/civic area where you regularly see addicts shooting up on the stairs as you walk down to bart. It is one of the worst areas of the city. Though it is getting nicer now that many companies are moving in.
What I've heard, no. That video was (probably) from a live stream.
> It's only poor engineering...

Poor policy, really. We should not be extending the operation of old plants.

The engineering is relatively poor based on what we now know about building and siting nuclear plants, but it was state of the art at the time.
A stiff land tax within major cities would probably be the most comprehensive solution. It would incentivize intensive use of land, leading to denser housing (compared to a property tax, which incentivizes the opposite); it would also make urban land a less compelling investment, leading to lower prices.
This comes up time and time again on HN. Due to the demographic here, everyone seems to know at least SOMEONE who makes $200K+, but there's no evidence that these compensation packages are anything but outliers (even including equity), no matter the age/vintage of company.
Modern cars with keyless entry typically draw ~50mA@12V when "off", this power is used to power the receiver, keep ECU state for such things as learned fuel maps, blink the alarm-on indicator, etc. 45Ah capacity gets you a bit over a month to drain down the battery, while 10Ah gets you a bit over a week. This isn't good, you'd have to keep it on a battery tender if you're not driving the car for just a week.

I can also see how one would implement a low voltage cutoff to prevent running down the battery, but then, how in the world do you automatically re-engage the battery to allow starting the car? You've shut off the power to the whole car, so you no longer have a circuit to monitor. If you're allowing some amount of current to trickle out, you must, by definition, be allowing the voltage to sag, which can run the ECU or alarm out of spec, causing havoc.

As the battery designer, your only input to make these decisions is the resistance of the car's electrical system.

The only thing you control is your own internal resistance.
The cleaning step.

Steps one through three are what is called "seasoning" the pan. It's a process that often makes a bunch of smoke. Ideally, you only ever have to do that once. Cooking on cast iron doesn't produce a smoky mess.
It depends on a lot of things of course, but yes, over the lifetime of the battery, it will pay for at least a large percentage of itself. We estimate about $10 a year gas savings.
The one other thing is to dramatically improve public transportation connections so that areas of the region that are currently not convenient for many people to live in become viable neighbourhoods.
Well just looking at Meetup.com

Django (excluding python specific):
MV: 2231, NYC: 2120, Austin: 41, Chicago: 126

RoR (excluding ruby only) MV: 4119, NYC: 4390, Austin: 158, Chicago: 417

I could probably go deeper but at least from a glance it is easy to see why starting in NYC or SF would be preferable.
You have a Honda?

The problem is I don't understand how the battery would shut down just lights and accessories without a) losing all your radio presets b) requiring entering the anti-theft code in the radio (risky because if you get it wrong you can brick your radio) c) still have power to know that you're trying to start the car.

It seems to me this requires more than internal battery smarts but changes to the car's wiring to have separate battery connections for computer, accessory, and starter.

Right now most cars have just one big post clamp for the + and - battery connections.
In recent news, many HN users avoid up-voting/commenting on things that disagree with pg/sama/etc. in the chance that their likelihood of getting into YC will be hindered.
I do think building up is a pretty good idea. I just wish it all currently in the Boston area wasn't luxury condos. And the existence of those luxury condos hasn't seemed to deflate the demand on other housing yet. Maybe in time?

If you have a limited amount of area and many many people that want to live there, something has to give. You can build up (which SF largely refuses to do) but even that has its limits and its costs.

The larger answer is changing things so not everyone wants to live in the same place.

Figuring out how more people could work remotely while remaining productive would have a huge payoff in this area. But I don't think that's particularly amenable to a wholly technical solution. It's more of a problem of applied psychology in the form of management techniques.

From a different direction, considerably better urban and regional mass transit would help. In the bay area, that's made much more difficult by the relatively small geographic size of SF proper as compared to the metro area. Compare NYC which incorporated its inner suburbs a century ago. Though on the upside at least all of the bay area is in one state.
Storing a lot of energy and delivering it faster are two separate problems. The batteries you linked are design to store a lot of energy, but are only rated to deliver it at 30Amps. Cranking even a medium sized sedan would take 5x that or more. Creating something that can do that reliably requires a lower energy density. LiFePO4 by itself also doesn't stand up particularly well to cold temperature. The capacitors do most of the heavy lifting involved in starting the car. Using the combination of the two also enables some other nice things like the dead battery prevention.
I disagree. IMO private messages shouldn't have the same limitation, and I think Twitter would actually benefit from carefully increasing public limits in two or three ways:

* Don't count attached images and single links towards the character limit (attaching an image leaves you with less than 140 characters)
* Don't count tweeting directly at someone towards the limit (additional @'s should count)
* Don't count the first hashtag towards it either

These changes would allow you to reply to someone, include the chat's hashtag, and include a single link or image, while still having 140 characters to express an idea. It wouldn't lead to massive clutter or abuse, but it would make public conversations less about the limits and abbreviations, which do hinder readability, and more about the content.

It can get really hard to express anything other than overly simplified, individual concepts in a chat, or reference external links, without eating up a substantial amount of the current character limit.
I've prototyped similar with just 7 maxwell caps in series wired in parallel with a lead-acid battery. The caps can start an engine entirely on their own, and the lead-acid maintains the voltage when off. It works fairly well.

I think someone already sells a device to work like that for commercial tractors, and I was wondering when someone more interested in starting a company than I am would realize you could have a tiny battery plus EDLCs for a car.
