He can reduce it if he only does first names. "316 Chrises, 241 Matts, 189 Justins, ..."

Cool idea. I'm glad I remembered how to say "ASS".

Typical morse code keyers have 2 buttons, long and short, so you don't have to worry about how long to hold it down. I think that would make this a lot easier.

I don't understand, what is the advantage over using Chrome's history menu?

People are complaining about how bad SWT is, and I definitely agree. It's a product of systems engineers, not the modern hipster-designer breed of developers.

If you fall into the latter category and want to work with Java, I highly recommend JavaFX Webview. It's essentially webkit as a UI layer, so you get to work with HTML5/Bootstrap/whatever. Surprisingly, its interface from Java to Javascript is quite well designed.

Will people really agree to an unpaid internship for some brand-new, unknown company? What's the reasoning there?

This can't really be viable unless it is for something where the attackers need ridiculously large scale. Hashcash was actually invented for preventing spam emails, where attackers are used to sending billions of messages per day.

Why not just use a subreddit?

If the fix was that easy, it would have been implemented by now. Doing so would prevent some useful behavior. For instance, an embeddable Facebook like button needs to run in an iframe and uses facebook.com cookies to be able to associate the like with the user.

I hope you realize you are accepting full risk for all your users' money by using Helloblock. You have a team of 5, is it really too much work to run your own node?

It took me a second to remember where I knew your name from. :P I used to always tell people to go to your site, once we put it up on a giant projector at a LAN party until nobody could take it anymore.

This makes me wonder what the longest Wikipedia article title is...

Make it say "HIRE ME!"

I don't really expect anyone to keep theirs after the initial novelty has worn off, it was just a quick, fun thing for me to make.

Hey, what happened to that flashing RGB thing with the catchy song on your website?

It's surprising to me that this project can get so much positive attention from developers, and even investors (according to their website). It is pretty critical that the people building the future Bitcoin ecosystem learn what sort of services they should stay away from.

Also, I wonder how much they paid for that domain.

It will take a week for that, and you only lose one column of pixels. If it still fits, you could prepend some spaces to your text to push it over a few months.

This is fine for learning about Bitcoin, but don't use this is in production. No matter how secure you think you are, someone can likely get into your server and serve their own JavaScript (making your clients send all their money and/or keys). Also, this tutorial uses a Bitcoin centralized service to communicate with the network, and you have to trust that they won't feed you false information/withhold transactions/perform malleability attacks.

Your username...

I think I misunderstood your README: "Unencrypted wallets are unsupported and are never written to disk. This design decision has the consequence of generating new wallets on the fly impossible: a frontend is required to provide a wallet encryption passphrase."

The README for the btcwallet library says that it needs to decrypt the root key every time it needs to derive a new address. With hierarchical deterministic keys, you can derive a public-only key, which lets you derive new public keys without needing to enter the password every time.

This has the benefit of less time for the unencrypted key to be vulnerable in memory and also ease-of-use since it can automatically search the blockchain for keys generated by the user. For application servers this adds a huge layer of security since you can accept money with the private keys fully airgapped.

The author misses the point that Kolmogorov Complexity isn't meant to be used as a practical measurement, but is just a theoretical way to think about information. There is no way to measure a string's "Kolmogorov Units", but you can just generally agree that "abababababababababababababababababababab" is less complex than "ababaaabbabaabaababbbabaababbbaaababbbba".

If you really wanted a practical standard measure, the language would have to be simple Turing machine instructions, so that the language implementation isn't more optimized for expressing certain things (which is the problem discussed in the post).

You're kidding, but some day, scanning people's brain structure and comparing would probably be pretty effective.

I've thought about how public chargers are something that businesses should start using. Imagine sitting down at a restaurant and getting a full charge during your meal.

If wireless charging gets more standard, then there won't be an eyesore of cables.

Hard to do effectively until we have consumer FMRI hardware that can measure dopamine/serotonin release.

Google could implement this very effectively when they have a couple self-driving cars going around each city scanning for empty parking spots.

Before then, you might have to do something hacky like user-submitted data.

A mobile app that scans for unsecured WiFi and automatically sends the location to the service. People who want free WiFi can search and find the closest one.

It's sure to cause some legal/moral controversy, but it is pretty trivial to implement and might be pretty interesting.

Instead of connecting to the people within 1 mile, it should be the n closest people. This would give the same effect, but work for anyone living in any population density.

The title made me think it was going to somehow be a vi-based editor (and that sounds like a good idea).

I like how having a lot of random stuff ends up making some natural-looking textures: http://zenphoton.com/#AAQAAkACAAEgdwAeAAsAKgArABMA/wAASgH9AF...
