With all the hype that do-it-yourself IoT is getting today, we're seing solderless boards connected to computers. That brings back good old memories to me. At the back of my books you can read that I controlled my electric train using an Atari ST. It was HO scale and I used the computer's parallel port connected to some relays. That was circa 1990. Well I don't have pictures of that but then I moved on to controlling a tinier train with a Psion Series 3 circa 1992. Same solderless boards and relays. I don't have pictures from that time either but I do still have the hardware, thanks to my parents: Unfortunately it's disconnected now, but wouldn't require much to get connected again. Between the parallel port and relays there where (one for each output) a transistor and a resistor. 8 relays, 8 resistors, 8 transistors: I managed to control 8 independent outputs. Which allowed me in turn to control the train's movement (forward, backwards), plus rail...

Just like last year I'm proud I'll speak at Dev Day Mons . Proud because this is a great event. My session will be the following: ASP.NET Core: why, how? Whatever your prior experience in the Web, we'll see why and how to build a web application with ASP.NET Core MVC. A great way to catch up with ASP.NET Core MVC in case you didn't get into it yet. All day long you can meet me at the lounge and get my signed books. Plus Dev Day attendees get a chance to win my books. Dev Day Mons is a one-day event where developers can catch up with hot development technologies in a nice and friendly environment. It takes place on November 28 2017 and you still have one week left to buy your early bird ticket for half the regular price. So get it now . PS: session description in French for those eager to know: Quelle que soit votre expérience préalable dans le Web, nous verrons pourquoi et comment réaliser une application web avec ASP.NET Core MVC. Au cours de ce...

Today I spent the whole day teaching code to 24 kindergarten kids. Each one of them programmed a Lego Mindstorms robotized fireman truck (they had just studied a lot about firemen), and then they coded a cartoon using Scratch Jr. That was a lot of fun for them and for me. They all enjoyed coding the truck and cartoon, and I'm suprised how far we got. I had planned teaching them about loops and basic actions (motors for the wheels and ladder for the truck, plus sounds and pauses) but they got me farther. Many asked about parallel actions and coded them, and some asked about conditions. Many asked about all Scratch blocks and used events. That's impressive for kids who had no previous contact with programming. I'm impressed by those kids. A funny moment was when some kids asked me if it was my job to do such things. When I answered yes, they told me I was overly lucky and that they want to be programers. Now I have a Mindstorms teaching kit for kindergar...
