I don’t understand why there isn’t a simple system where you register your interest in vaccine, age, medical conditions and leave your contact info to be called in when your shot is ready.

I think issuing fiat money and setting price of credit by fiat are two faces of the same coin. I think the way real interest rates behaved under the "Gold Standard" would be close to an answer to your question.

Yeah, I admit my comparison to the subway costs was not fair.

Still, let them try something new. What have you got to lose? If the R&D work they're doing here results in even marginal improvements in tunneling technology, I'd call this a win for everyone.

Yeah, that's fair, but no reason why we shouldn't do both. Unfortunately the US government is not gonna make that happen any time soon.

Yeah, those subway networks cost $2.7 billion per mile (in NYC) and take decades to complete. He managed to do it in a couple of years at an estimated cost of $10 million. Even if that number is wrong by an order of magnitude this is a massive improvement.

The "Elon Musk" persona is no doubt annoying, but is that a reason to undermine and shoot down new ideas? Don't let your schadenfreude get in the way of recognizing real achievements.

Cars are an established industry too...

I really don't understand all the cynicism around this. It's a prototype of a bold idea, in all likelihood it will fail (like most bold new ideas), but at least they're trying something new. That's how change happens, through trial and error, not through foolproof, perfectly executed plans. For better or for worse, Elon Musk has a track record of taking difficult ideas and beating all odds to make them a reality.

If you wanna call out Elon Musk for something, call him out for his abusive management practices and erratic/abusive behavior on twitter. Calling him out for trying out bold ideas (with all the trial and error that entails) is really petty and counterproductive.

> So i know what local echo is. It has nothing to do with prediction :)

Not precisely, because you're sometimes predicting whether a keypress should be rendered as a letter on the screen or not (e.g. if you click 'j' in vim command mode it doesn't actually print j). mosh, at least from my experimentation, seems smart enough to do that reliably.

That's not what mosh is, it doesn't predict what you're going to type. It however proactively renders the characters you type before it receives confirmation from the tty on the other end.

In other words, imagine typing ssh somebox.typo.com and waiting 1 second before the text renders and discovering the typo, then pressing backspace, waiting a while for the backspaces to render, then going through all of this again. With mosh you'll be able to instantly see what you typed and fix it. On high latency connections it makes a huge difference in quality of life.

Your payment form is not secure, even though it makes a submission over SSL, the fact that it is hosted on a non-SSL page exposes it to Man in the Middle attacks. An attacker may, for example, change the iframe URL to something controlled by the attacker but looks like the payment form on your site, and trick users into giving them their credit card details.

The fix is simple, make your whole site https and redirect all http traffic over to https. There are cheap SSL certificates out there (as low as $99 a year) and its pretty easy to setup.

Or you can just select the block of text and type gq. This will do what par does, and can be adjusted with vim's 'textwidth' and 'formatoptions' settings.

This behavior can be turned off by adding this to .zshrc:

  setopt no_nomatch # if there are no matches for globs, leave them alone and execute the command

zsh also tries to autocomplete directory names using variables in global namespace that point to directories. I found that behavior maddening and can be turned off with:

  setopt no_cdable_vars # don't use named directories in cd autocompletion

The problem with graphical programming is that it is inefficient when it comes to using a large API. There are only so many icons and graphical objects you can fit on a screen, while still making it easy for users to find them.

That's why they are restrictive, they have to choose only a narrow set of methods to expose to the users. By narrowing their available functionality they also become useful for a smaller domain of problems.

Codify does not try to replace text-based programming, but instead to make it easier and sometimes more efficient for graphics-intensive programming. For example, the easy to reach color selector is much faster than having to use a separate tool to get the numbers for the color you want. Same thing for the image selector.

Did Netflix really jump from 15.9 million subscribers in 2010 to 25.6 million in June 2011? That's an increase of about 10 million subscribers in about a year, compared to an increase of 3.6 million between 2009-2010.

I don't think there is a need to use the tracking software to build a case against the burglar. They caught him with stolen property and have fingerprints. No need to go high-tech here.

zsh can be a shoein replacement for bash, and its globbing facilities makes 'find' almost obsolete for me. For example:

  find . -name "*.css"

is:

  ls -d **/*.css

in zsh. Other examples, all derived from the article:

  find . -type f -name "*.css" ==> ls **/*.css(.)
  
  find . -name "*.css" -exec grep -l "#content" {} \; 
         ==> grep -l "#content" **/*.css

  find . -ctime -1 -type f ==> ls **/*(.c-1)

  find . \! -path "*CVS*" -type f -name "*.css" 
         ==> ls **/*.css(.e{'echo $REPLY | grep -v "CVS"'})

More can be found in the "Glob Qualifiers" section of the zshexpn(1) man page.
