Find the kind of businesses that you want to help, and offer a free trial and coaching for 30 days. The early customers are there for you to learn from so you shouldn't expect them to pay you (yet.) Building a lead database of the kind

I got an Echo during beta, and there was no API at all. Later, they opened up the API. They've had enough time to make it useful by now (like, answering more than one question in turn!) but it's still not 100%. Meanwhile, Google H

Berkeley Unix (or was that SunOS?) used to cone with btoa that used base 85, packing 4 bytes into 5 uucp/mail/Usenet safe characters. For some reason, base 64 became the standard, and I don't think there's space for anyt

Actually, the reason they inject ethanol (by law) is to reduce asthma and cancer. So I'm okay with that.

Yes, because a fake Comcast hotspot surely wouldn't display Comcast ads to make the fake complete? Comcast understands that politics works on money and connections, not facts, and had learned to play that game to great profit for thems

If TLS/HTTPS was easy to use from userspace C, HTTP could probably phase out very soon. Node, Go, Python, and other web tech actually makes this easier, because I don't have to call OpenSSL myself. So, even though I really love C,

I need a GPU and as much RAM as possible to run VMs. The new MBP, with wimpy graphics and 16 GB of RAM, does worse than a Razer Blade (also USB C, has been out since early 2016)

Why would you need to counter it? If it's right, it's right! The fact that US offices are designed to maximize return on real estate investment, not knowledge worker productivity, is well known. I wish our screens were better so t

Deliver better. Success comes in execution, not idea. Also, first movers don't always win, because second movers can learn without maintaining legacy. Who would you rather be? MySpace or Facebook? Alta Vista or Google? ICQ or Skype?

Actually, it has to do with the oxide layer in the Lithium battery. Good temperatures make it degrade slower, but it still degrades. LiFePO4 degrades slower than LiPo by a factor of 5 or better, but has lower power density (3.2V instead of

The voltage of the interconnect doesn't need to match the voltage at the capacitor. Buck converters for the win!

A Deans T connector is rated at 50A long term. For shorter time, it can carry more. (It's a matter of current times resistance minus thermal dissipation.)

The internal resistance of supercaps is higher than that, they cannot discharge in microseconds. Think about it: 5V 3F into 10 microseconds would require a resistance of micro-ohms, which is less than the resistance of the connecting wires.

18A is not a problem in itself, because the voltage isn't that high. Your drone likely draws more than 18A. Your car starter draws 10x that. High current just needs thick wires. 120V wall power, with a proper power supply, needs 1A or

Let's reframe the question: Why does society today not attempt to maximize happiness among all citizens? Resources are expended to make those with more resources marginally more happy, rather than someone with less resources comparativ

A password is safely stored in my brain and 100% portable. I can use it from whatever location. If I lose my computer, the password is not in the hands of bad guys. Not so with a client cert.

If you were convinced that the data and physics undeniably show that we're headed for a point where the global food supply system will collapse. And you believe all previous criticism has been adequately answered as nauseum. And you ex

They are not just outside the mainstream, but fundamentally not backed up by known physics and statistics.

I rather like the "everything is quantized and this is a result of accumulated truncation errors" theory.

If they feed electricity into the microwave horn, how strong is the induced magnetic field around the wires? Would that push against anything? How is that compensated for in measurements?

Confirmation bias much? Why don't we focus on the actual data? Sun activity is not a major driver of warming, according to data. Yet, this position paper names sun activity as a cause to dismiss atmosphere. Why is that, do you think?

Yes! Because primes are infinite! The statement assumes limited primes. And, because it falsifies, it proves primes must be unlimited. I find this argument based on prime factors much simpler.

It is said that, in a war of ideology, you cannot bring facts. But, what if facts are your ideology? This is the conundrum we're facing.

The question is: Solving what problems, at what scale? If you're a profitable company with a sizeable userbase, just buy Salesforce. It's clunky, it's expensive, but you can find contractors really easily to make it do whatev
