A Bitcoin like protocol for sending/receiving real money (USD, INR). Why to pay 2% to banks and card processors when we can use blockchain for the same.

#152A/B testing for the masses. Here's an example: Say a someone is deciding which shirt to wear. They whip out their smartphone, launch the A/B app, takes a picture of themselves wearing each of two shirts. Within 30 seconds, they have an answer of which shirt hundreds of people liked better. While they're waiting for the reply, they're prompted to rate other people's pictures. This is as simple as seeing two pictures a…
This is actually pretty interesting. I think many people have thought of a product along these lines and, as mentioned by others, there have been several versions of this tried. I think the key is in the constraints you have outlined. Obviously it's a mobile app. You take two pics and post. You then vote on other's ABs. Every vote you make on someone else's AB earns you a vote on your own. If you want a bunch of opin…
I mentioned this idea to a client some time ago, exactly like this. Each vote gives you a vote on your own pictures. It was not in the scope of the product but I do still like the idea.

It's limited to pictures of people, but MyBestFace sounds like what you're describing. https://www.okcupid.com/mybestface
You're right, the methodology is similar, just for different goals. That one is trying to figure out which picture to use for your profile, whereas this app is trying to help you in making every-day decisions such as what to wear or what to buy. A key element is the response time -- I'm not sure how fast this service gets you an answer but I'm assuming it's not within seconds.

#154"please", a command-line interface for natural language commands. So, like Siri, but for your terminal. Ie: $ please push the changes i've made today to the master repo $ please archive this directory into foo.zip $ please clone the bootstrap repo from github $ please find any files under ~/ matching 'foo-*.txt' and containing 'bar' Sure, all of these can be expressed using CLI tools we have today, but isn't it time…
I'd wager that ANY person who actually uses CLI tools to do things does not want, nor need, to write full sentences to do these things. Everyone that uses CLI tools always says they do so because it is the fastest way possible to do X. That point becomes moot once you have to write sentences.

I'm just some guy, you know? But this sounds awesome to me. Maybe the trick, compared with Fashism (really?), which seems to have been about feedback on your Fashion more generally and pickfu which seems to address feedback more generally, the trick would be to really narrow it down.
To just an app for two photos, which is better, and let people make of it what they will. Would need decent facebook integration, so you can ask your friends, not just random strangers.

Well, their slow response time is presumably because that's the best they can do.... how would you improve on it?

#157A service that sits between my bank account and subscription services that only accepts charges that I've preapproved. This would let me keep track of the services that I have so I don't end up with subscriptions to sites or services that I've forgotten about. It would also let me revoke permission to charge the account at any time. No need to cancel a card if one won't cancel or changes the fees--you just revoke the…
Direct Debit in the UK does this. You can cancel any instruction at any time, usually through your online banking where all instructions and charges are listed. It is widespread and the norm for subscriptions.
Same here in Portugal. And we also have free virtual CCs with predefined limits.

I see what you are saying and I like it a lot. I think you would still need a way to have people discover the current state you live in. One thing that comes to mind is taxes that differ per state. If I told amazon to ship my package to bob@foo.bar they would still need to know where I live.
You give Amazon your ID number. They do a lookup on the ID when you place an order to receive the current mailing address. It would apply to everything, so you give all of your friends and family your mailing ID. Anytime they want to send you something, they run a lookup on the ID (enter it into a website) and get your current address. It's similar to a website. If HN moves to another server, everyone doesn't have to…
I think it would only work if the USPTO was in on it, instead of forcing everyone to look up the address. It should still be publicly available (for the Amazon case, and such), but not required just to send something.

I don't know - I live in the terminal, and I definitively wouldn't use it for regular commands (sed, grep, tar, etc), but if it was smart enough, I could see myself using it for software that I rarely use and which has complicated options.
For example, I'd rather type
please convert movie.avi to h264 at 720p with subtitles from movie.srt
Bonus points if it could print the translated command before running it - it'd double as a learning tool.

> Isn't that what your own name does? I've never heard of anyone being able to send mail to a person using only their name on an envelope. You would have a unique "ID" which you can assign to any physical address. This is all you ever give out. If you move, you update one record, and your mail will come to the right place.

Interestingly enough a colleague of mine managed to send a post card to himself from a different country using only his email address as identifier. Of course the email address was on the form
@..
so it should have been fairly easy to route.
