Temperature: I can't stand more than 25 °C (well, I can, but I don't like it).

Big software: I missed the old times where you just needed a text editor and a terminal in order to "create" computer programs. Nowadays it seems that you need IDEs (specially in mobile development), frameworks, unit testing frameworks, CI servers; and you have all types of "mini software programs" you have to use just because your team says "it's great". For example: Jasmine, Bower, Composer, Rake, Pip, Grunt, Gulp, Browserify, etc. I know all of them are pretty useful (and I would say, indispensable). Yeah, I know that the new rule in software development today is "write big-readable-maintainable-scalable-featurable software"... but as I've said I miss the little less-featured programs (like "ls").

Money: not to be able to buy online without a credit card. I would love to go to a physical store and buy a "pseudo credit card": "Hey dude, here you have 50 euros, give me a temporary credit card for that value". And then go to Amazon or whatever online shop and use that pseudo credit card without give any of my personal information or have to link the pseudo credit card with my bank account (like PayPal does).

Politics: I would love to see some engineers or scientists working in politics. I only see lawyers, economists and the like.

About the pseudo credit card, in Portugal (where I'm from) we have a system called mbnet [1] where any portuguese bank account owner may create a temporary credit card. I usually use it for buying things online. This card has some security restrictions: you can specify if it's going to be used for 1 or more transactions and the top amount of the transaction. It works pretty well.

You can buy pre-loaded credit cards at gas stations in the US, although I'm not sure how they work for online orders.

Just fine, I've used temp cards several times for that exact use-case.
