Artificial intelligence (AI) seems poised to run most of the world these days: it’s detecting skin cancer, looking for hate speech on Facebook, and even flagging possible lies in police reports in Spain. But AIs aren’t all run by mega-corporations and governments, you can download some algorithms and play with them yourself, with often hilarious results.

Github is an excellent resource for programmers of all levels and serves as a great repository of readily available software and development tools. The website is a chore to use on anything other than a desktop, but that could soon change thanks to a new dedicated app that GitHub is asking you to help beta test.

I’ve always wanted to learn how to code. I’d like to at least learn enough of a programming language to create some basic automations — or figure out some neat ways to control the various LED lighting kits I own.

When I was a kid, I couldn’t have imagined learning to code, build a website or create an app or a game. (OK, I still can’t imagine doing those things, but I can’t even properly work my son’s Kindle Fire, so I’m a bit of a mess when it comes to technology.) Our digital native children, however, eat this stuff up.

There are a lot of good reasons to delete your tweets, but I’ve been hesitant to pull the trigger. While the idea makes sense on paper, I know there are things I will regret erasing. We’ve recommended services to clear your Twitter before, but as far as I know, all of them delete your whole history. It’s all or nothing.

If you want to teach your kid how to code, there’s certainly no shortage of apps, iPad-connected toys, motorised kits and programmable pets that you can buy for your future Google employee. Some are great, no doubt, but many focus on isolated skills, which may or may not be relevant in the decades ahead. For young children, what might be more critical than learning to code is learning how to think like a coder. And for that, they don’t even need a computer.

There are so many ways to learn web development, your problem might be how to choose a starting point. The design site CSS-Tricks has their own guide for learning HTML and CSS — but they’ve compiled plenty of alternatives into a wide-ranging but approachable list.

Starting December 1, you can learn a bit of code for free at your local Apple Store. The retailer’s annual ‘Hour of Code’ event runs from December 1 to December 14 - and most Aussie stores are participating. Here are the details!

If you want to learn how to code, there are a ton of resources out there to help you learn how. Websites like Codecademy, Udacity, and Khan Academy can help you kick the tires a little bit and see if coding is for you. This week, a group from Google launched another option, a mobile app called Grasshopper that can help you learn Javascript during your morning commute.

Coding school App Academy has opened a free online interactive version of its 12-week curriculum. That’s a pretty good deal, since the Academy’s in-person classes in San Francisco and New York can cost as much as a semester in university. The online version involves less direct human interaction, but it includes online mentors and access to a community Slack chat.

There are as many ways to learn to code as there are ways to use your coding ability. You can learn it from college courses, books, online resources — or from one of several growing boot camps for developers of all ages. We talked to the founders of two such boot camps: David Graham of Code Ninjas, for kids 7–14 and Michael Choi of Coding Dojo, for teens and adults. They explained their different approaches, both of which give their students the ability to build their own applications.

Keen to set your kids up for the future? Here's 10 ways to get them coding.

Dear Lifehacker, I'm a teenager in year 10 and I've started looking at things like programming and coding. I was wondering if you could tell me how to get started with programs like C and Python? I've struggled to find helpful tutorials online for teenagers.

If you're new to building web apps, check out the first issue of You Got This! a friendly zine from developer community Glitch. The issue teaches the basic concepts behind web servers, and the npm package manager for Javascript. It also features career profiles of three community-leading web developers, and blurbs of advice from a dozen more developers from places such as Google, Mozilla and Slack.

Machine learning (AKA AI) seems bizarre and complicated. It's the tech behind image and speech recognition, recommendation systems, and all kinds of tasks that computers used to be really bad at but are now really good at. It involves teaching a computer to teach itself. And you can learn to do it in well under a year, according to data scientist Bargava. You'll need to put in a solid 10-20 hours a week, but you will learn a lot along the way.
