"Oh yeah, EVs have very little moving parts so they will last 2x or 3x as long as normal cars. Perhaps three or four decades or 500k miles."

Do the batteries last that long? (They're about half the price of the car currently.) Last I knew, lithium-ion batteries lose capacity over clock-time. Some types lose capacity less soon than laptop/phone batteries[1], but I didn't quickly find out how much slower, nor what type of battery Tesla is using. (Do you have info?) Maybe we can't even know: lithium-ion batteries were only invented 40 years ago[2], and modern Li-ion chemistry and size much more recently.

Its ok, I don't have their interests at heart either. That's what business is.

What happens when one of these services go away? I will make other arrangements.

I wouldn't start using a service if the value of the convenience/savings gained, combined with how long I think it will be available, weren't a better deal than the alternatives.

But, yeah, I'd rather own some things than rent them. Movies used to be one of those things, but there's no way I could buy and store all the things I can see on netflix.

I'd still rather own my music. But I will listen to a song hundreds or even thousands of times.
Oh, okay. In that case you want to look at transactional email services. MailChimp offers that as well with https://mandrill.com, but there are a ton of other offerings as well like http://sendgrid.com.
I suspect that eventually we're going to start integrating chip-scale atomic clocks[1] into our mobile devices, which will allow a much longer synchronisation period. Right now they're still ~35g and ~130mW power, but that's only going down. There's going to be a whole bunch of interesting new distributed processing stuff you can do with highly accurate synchronised nodes; something like the Google Spanner system on a more local scale, perhaps.

Finding a good name for your startup is becoming more difficult each day
No, consumer reviews are a replacement for safety inspections. The morbid side of me says "dead men post no reviews". But the real problem is how many people would need to be hurt (financially or physically) before enough reviews got out? If its one then a seller could be held hostage by a single bad review(legitimate or otherwise).
"Hewlett-Packard’s acquisition last year of the British software maker Autonomy for $11.1 billion “may be worse than Time Warner,” Toni Sacconaghi, the respected technology analyst at Sanford C. Bernstein, told me, a view that was echoed this week by several H.P. analysts, rivals and disgruntled investors.

Last week, H.P. stunned investors still reeling from more than a year of management upheavals, corporate blunders and disappointing earnings when it said it was writing down $8.8 billion of its acquisition of Autonomy, in effect admitting that it had overpaid by an astonishing 79 percent."

Doesn't that mean they overpaid by 482 percent? It is true that the acquisition lost 79 percent of its value, but the editor seems to have gotten the math wrong here.

Something I still wish I had done for my current startup is pitching the idea to the companies it can benefit most and offer them to work on it freelance for half your usual rate while keeping full IP.

That would allow you to work on your startup, validate the idea and providing income.

It may be somewhat interesting to analyze the properties of randomly-generated labyrinths of this type.

For instance, some spaces are clearly enclosed. i.e., there is a finite border outside which you cannot escape. Some paths seem to run on for a very long time. Are all paths enclosed? If so, given a random point on a randomly generated maze, what is the average area of an enclosure?
So I did a non-scientific test on my Raspberry Pi at home with a 4G card that has typically been my 'move an .iso around' it is a 'class 10' card from Microcenter Warehouse. Using this perl program:

use warnings;

my $letters = "ABCEDEGHIJKLMNOPQRSTUVWXYZ-";
my $range = length $letters;

while (1) {
foreach (1..16) {
my $nm = "A";
foreach (1 .. 15) {
$nm .= substr($letters, rand($range), 1);
}
open(my $fh, ">", "$nm.delete-me");
foreach (1 .. 128) {
$nm .= substr($letters, rand($range), 1);
}
print $fh "$nm\n";

My hobby is weightlifing. About 3 weeks out from a competition I systematically wean myself off caffeine by substituting more and more decaf into my regular coffee until I'm purely on decaf.

Why? Two reasons.

The first is tolerance. Caffeine tolerance reduces the sense of freshness, alertness, energy etc that coffee gives for any given dose. But tolerance isn't a linear function for all the effects of caffeeine.

The practical upshot is that, on competition day, I wind up needing more caffeine than usual to give me the extra pep to really perform well. But if I'm already tolerant to caffeine, my "pep" dose will be high enough to cause sweaty hands and to degrade my motor control -- in my case my grip becomes weaker and my pulls are not as crisp. Olympic-style weightlifting is a precision sport; I can't afford that.

Whereas, if I've weaned myself off caffeine over the preceding weeks, there's been adenosine re-regulation and I've become more sensitised to it again. So I can get all the pep and energy to push through a competition (it can be very draining with all the warm up lifts) without the sweaty hands or weaker grip or less accurate pulling technique.

The second reason to wean myself is that going cold turkey is absolute hell.

One rule I observe these days is that I don't consume caffeine after 1pm. I can't get to sleep otherwise. In practice this means two cups a day: one when I wake up, one before or during lunch. Even after the noticeable effects of caffeine have faded, it has enough of a half life to make it difficult to fall asleep in a timely fashion. Then you get stuck in the caffeine-sleeplessness-caffeine feedback loop. Worth avoiding.

I don't get the hype around evernote. I find their app rather clunky, but more importantly their security story is a disaster waiting to happen. Last I checked encryption was only available selectively for individual notes, and again the UI was so clunky that it's probably hardly being used.

Thus it takes only one disgruntled employee or motivated cracker to make many people very, very unhappy.
We talked with some popular "mysql consultants" about things like mysql-master-ha and there was always a lot of hand waving murmuring about how existing solutions were incomplete / had lots of bugs / were not to be trusted in production.

It looks to me like they do mostly the same thing. We wrote our script in Ruby because it's what we know and have the most expertise with, which makes it easy for us to debug.

mysql_role_swap is not black magic, it doesn't do automatic failover, it doesn't run in the background / daemonize itself. It fails gracefully in a way we find predictable and useful.
The article makes a point of comparing the mergers to the broader economic conditions at the time. HP acquired Autonomy and lost money at a time when the computer industry was (and still is) growing.

On the other hand, AOL and Time Warner merged right before the bubble burst and BoA acquired Merrill Lynch at the same time the economy was crashing. Without the acquisition, Merrill would have gone bankrupt anyway and BoA's market cap would have cratered anyway because the entire financial sector was cratering at the same time. In fact, the US government heavily pressured (threatened) BoA into acquiring Merrill (http://www.washingtonpost.com/wp-dyn/content/article/2009/04...).

So no, they're much different cases.

Yeah, I get a headache when miss my dose. I have a variable schedule which causes that to happen about every other week so I've stopped drinking tea or coffee on any kind of regular basis. Now I only drink some when I need it and usually not more than once a week.

When you don't drink it all the time even a small cup goes a really long way, at least for me.

They have the location, gender, sophisticated rule systems (to which they could add marriage laws), and a manual review system. If it became important to them to have peoples' marriages in their systems they could probably put such a system together.

I think it would be like complying with China in filtering their results where they could argue that somehow working within the system is more helpful than working outside the system. They could say that it would just give people who couldn't get legally married more incentive to become politically involved.

http://en.wikipedia.org/wiki/Criticism_of_Google#China

Google could provide a marriage API that would allow companies, like insurers, to have their system check if people are married, to determine benefits. Building law checking into their system might not target people who are attempting fraud, but removing false entries of any kind could increase the reputation of the system.

The Autonomy debacle aside, what has Meg Whitman accomplished since she took over HP ? After a long tortured process that needn't take so long, she enshrined WebOS's abandonment. And with her at the helm, HP continues to fail to innovate in the consumer electronics space. No decent phones, No compelling tablet, not even a laptop worth glossing over. Zilch.

When is she going move on from blaming her failed predecessors for their missteps & actually put an imprint of her own.

It's not a binary proposition. You can have puppet institute and you can have a completely independent one. Usually you'll get something in between. I don't think that Vanderbilt's quality has a lot to do with it.

This next bit may be a bit cynical:

Even if they weren't funded by the coffee industry, however, they would have existential issues. If their whole purpose is to study coffee then I think that there will be a tendency to either promote coffee or to try to strike a balance. The latter is almost as bad as the former.

Maybe I'm wrong. Maybe they would have no problem publishing nothing about negative results if that was what they got, but I would bet against it. If they get a string of negative results (and don't lose their funding), they are going to start looking for studies that have a more potential upside to balance things out.
I don't think pursuing revenue/profit is the first thing you should do. Education projects need sometime to 'get going'. My advice is start doing it in the weekends, find a few users, see what they love, change what they hate, find more users and iterate until you can leave you job.

Another thing, put someone aboard. If you can't convice your best friend (or somebody close) that it's a good idea, maybe you wouldn't convice a VC or pg.

Semantic layout of UIViews IOS library
I enjoy a simple little tool that makes embedding user content easier.

However, the problem with user-generated JavaScript is not security, it's termination. To my knowledge, there is no 100% safe way to prevent a user script from locking up the thread/tab/process without completely restructuring it. Looking at you, Google Caja. Iframe solutions will reduce the attack vectors to your page, but they will not keep it from locking up. So if you have user-generated content that is displayed on your main page/feed, make sure you don't allow JavaScript until there is a 99.5% sure way to determine script lockup pre-execution.

Seat-belts were invented more than a 100 years before they were mandated by the government. They were available as options on Ford vehicles more than 25 years before they were mandated by the government.

I'm sure the seat-belt manufacturers had nothing to do with them becoming mandatory, right?

Remember, I said regulation requires two components. A business interest with money to "grease the wheels" of government and a public interest component that convinces the public that it's wonderful for them. The seat-belt manufacturers provided the former, Mr. Nader the later. There doesn't need to be direct cooperation. Merely the presence of both.

Not that seat-belts don't save lives, they certainly do, but don't kid yourself ... there is always somebody who wins and somebody who loses with each regulation passed, somebody who makes money and someone who loses just smidgen of their liberty.

Again, read Adam Smith.

> obliging taxis to take you anywhere within the city limits

> must take an extensive test requiring memorisation of virtually every street

Both of these could be things the bigger taxi companies already did willingly, but then pushed for legislation when competing upstarts began undercutting them by offering service only to high traffic routes. If the big taxi companies already do it, they are unharmed by the legislation, but competing companies much spend resources to follow the new regulations.
Interesting theory, but the productivity is almost entirely due to not having to write large blocks of code. For example, in our last project, I didn't have to write an admin interface, users, roles, authentication, tagging, forms and more. The messiness was tangential, not useful.

I think what you mean is credentialling, not "grading". Education and credentials only loosely overlap. My understanding of history is that this credentials vs education thing is a long standing problem. I don't foresee it ever really being resolved.

I would love to use the Internet as a means to educate people. I am still trying to figure out how. Among other things, I would like to create a simulation (aka "game"). That's a longstanding dream. I have done things like start a design doc, but sometimes it seems like the dreams I have are impossible dreams.

Effectively reaching your target audience is the big challenge. I think it only gets bigger with the Internet because of the huge diversity of people online.
Don't the landlords put these clauses in their contracts to conform to mandatory laws (like zoning)? If that's the case, then it seems like a bit of a stretch to consider that a voluntary agreement.
I strongly endorse this idea. The faster and more completely the development community moves away from using PHP in production, the better. I've started telling people not that PHP is bad, but that PHP is the avatar of technical debt. No matter what you personally do with PHP, the creators of the language and the other participants in the PHP ecosystem make it impossible to create a significant project in PHP without taking on ruinous amounts of technical debt - some of which takes the form of critical security problems! Python and Ruby, despite their faults, are more secure by default and have better security teams.

So in summary, I bet that purging PHP was tough, and I think you made the right choice.
