Really? Your employer doesn't tell you what's expected of you?

Being quite a large company, my employer has a fairly heavyweight goals management system, in which you and your manager set expectations, then measure yourself against them during the following year.

We have no idea what Satoshi's success criteria were. so how can Bitcoin be a failure?

Perhaps the aim was for Bitcoin to be routinely used by almost everyone in the world -- in which case, yes, it'll probably fail, but that would have been an outrageous target.
Perhaps the aim was for it to become useful to a few thousand niche users -- in which case it's already a success.
Perhaps the aim was just to see what happens -- in which case it can't fail.

Bitcoin is what it is -- and it's interesting to watch.

... if I worked from home or had a private office.

As it is, in an open-plan office, I don't want to disturb my colleagues, or feed them a constant stream of what I'm searching for.

However, I've only just started using voice on my Nexus 4. I'd simply assumed it wouldn't work well enough, but I gave it a go when I wanted to send a text in a hurry -- and was astonished to find that it *faultlessly* transcribed "I'm on my way. If I'm not there in ten minutes avenge my death", spoken at full speed.

So since then I've checked out the full range of voice instructions, and plenty of them are useful.

Not if it's a legal mandate, so every other shop is charging the same for bags.

Take a bag with you to the shop. It's not difficult.

Well, I don't know about you, but I hardly need bags for general waste any more.

All food waste either goes into my own compost, or into the green wheelie bin for composting by the council -- my council now accepts meat and cooked leftovers.

Paper, cardboard, metal, glass and plastic packaging goes in a recycling box for kerbside collection.

That leaves a very small amount of other waste, to go in the grey wheelie bin. It's seldom a quarter-full when the fortnightly collection day comes. There's just no need for bags, because it's all dry.

If you feel you need trash bags, you should pay for them. You can either pay for carrier bags, which you then re-use as trash bags, or (cheaper) buy a roll of actual trash bags.

Yes, and everybody got used to it really quickly.

Even though it's a negligible charge, people tend to react by carrying a couple of spare carrier bags with them in case they go to a shop.

Effective against what? A Parrot AR Drone (the hobby UAV under test) is about 57cm across. Much less than that side-on.

That's a pretty tiny target at 600 meters distance.

Beautifully put, and correct.

However:

Which makes it notable. Before you use a consumer-oriented item for more serious use, you need to evaluate its fitness for purpose.

Of course, you might go ahead and use it anyway - that's what risk assessment is all about.

With all your accomplishments, how does it makes you feel that the introduction to this Q&A begins with your hair?

Seriously, would we do this for a male engineer?

Any language that cross-compiles to JS is cross-browser. Correct.

I love what Minter did with Tempest to create Space Giraffe - Xbox 360 and later PC.

Lots of people don't get it, but that's because they haven't taken the time to understand it properly. I urge you to try it out, with the "missing manual" http://minotaurproject.co.uk/SpaceGiraffe/walkthrough.php

I'm not sure I can love a simple Tempest any more.

Quite.

"Every day I find my bike tyre has gone flat, and my crappy pump takes 10 minutes to inflate it. So I'm getting a better pump."

Both rate-limiting and captchas protect against brute force password attacks.

Whether you need both (or either) is up for discussion, and probably depends on your application.

Security is often annoying. Entering passwords is annoying. Getting RSA keyfobs out of your pocket is annoying.

When it's used to protect against brute force password attacks, a captcha is definitely a security mechanism.

When it's used to discourage spam, well, it's on the edge of the fuzzy area most people understand by "security". It's protecting the availability of a service, against the threat of spam making it unusable.

Fine. Add that to the criteria.
