This seems to be, quite obviously, an attempt at free marketing. They want to be able to point at the corpus of products influenced by SO, and say "see, we're pretty cool". Seems m…

There are several connections between Lambda and functional programming. 1. The snippets of code you run in Lambda are called "cloud functions". 2. Lambda applications are generall…

Your code looks correct. I would expect something closer to 50ms in the warm path (300ms in the cold path seems about right). I'll take a look tomorrow and see if I can reproduce w…

Lambda has a fairly generous free tier. Here are the details on pricing: https://aws.amazon.com/lambda/pricing/ You get up to 1M requests / month and 400,000 GB-seconds of compute …

Are you using Node.js or Java for your Lambda function? If you are using "Node.js", you may be seeing slow times if you are not calling "context.done" in the correct place, or if y…

In a leader election, a node won't vote for a candidate that doesn't have a record it believes to be committed. Thus, writing to a majority ensures that when the leader dies, the n…

A few things: 1. You don't have to round trip to every member before acking a write request, only to a majority of them. 2. If you use the right data structures for your state mach…

This is a nitpick, but it is lazy. It's not represented in head normal form, but it's still lazy. The limitations you mentioned are not an artifact of the implementation being eage…

Something like that may work for digital goods. You deliver some digital assets, the key to which can only be derived if a particular crypto currency transaction is performed. But …

There's an interesting split here: between contract validation, contract enforcement. Both have typically been handled by courts. Contract validation is typically very "human centr…

There are already 1M apps in the App Store. There's already too many apps, so preventing "over choice" isn't their goal.

A shelf space analogy doesn't make sense. With a real shelf, there is scarcity. Only so many shelves can fit in the store, and only so many products on a shelf. The marginal cost o…

In war, identity is a defined "negatively". That is, not by describing positive attributes to you, but by describing negative attributes to the enemy. "We are the opposite of x", h…

Is there any better way to change someone's mind, to change their fundamental mode of thought, to alter their perceptions and manner of reason than to educate them? Here's an even …

That's the whole point. It's disruptive technology: not as good, way more accessible.

This bothers me. I know this is a bit of a 'libertarian fantasy', but I think the constitution ought to be amended to contain something like the following: 1) No person shall be su…

The key take away from the article SHOULD be: don't rely on ntp if you don't have to. There are people who have to. They run their own atomic clocks, and worry about things such as…

I won't argue that constraints can lead to innovation. All art exists in some medium. Constraints are therefore inherit. Here's a simple question: what spurred Picaso's decision to…

Sigh. Not about the original article, but about the top comment in the original article. It presumes that Picaso, Bansky, and Monet can't paint like each other. Probably not true i…

Actually he has admitted he was wrong about the iPhone, thinking of it as a high end phone instead of a low end (but very convienient) computer. The author of the article, I think,…

The most interesting part is that the difference in votes is exactly equal to the number of individuals marked as "not voting".

Actually, no they couldn't. Patents only apply to the right of "first sale". You can resell any patented invention without the consent of the patent holder.

Jason has a point: You can maximize revenue by focusing on delivering higher value features to more lucrative customers. But, you need to be careful when following his advice. Blin…

If there was a sudden dramatic rise in the number of cases approaching trial, the natural response would be to increase the value of plea deals until the number of trials drops to …
