Asynchronous Socket Programming What is 'asynchronous socket programming'? a.k.a. event-driven programming or select()-based multiplexing, it's a solution to a network programming problem: How do I talk to bunch of different network connections at once, all within one process/thread? Let's say you're writing a database server that accepts requests via a tcp connection. If you expect to have many simultaneous requests coming in, you might look at the following options: synchronous: you handle one request at a time, each in turn. pros: simple cons: any one request can hold up all the other requests fork: you start a new process to handle each request. pros: easy cons: does not scale well, hundreds of connections means hundreds of processes. fork() is the Unix programmer's hammer.
Teach Coding in the Classroom: Resources from ISTE '14 I was super excited to attend Hack Education (originally called “EdubloggerCon”), an all-day unconference held the Friday before the formal start of ISTE 2014. This interactive day of learning, now in its eighth year, was touted to me as the event to attend in Atlanta, and it did not disappoint. The informal, small-group conversations were inclusive and welcoming. The "rule of two feet" meant that if you needed to move, you were encouraged. And session topics were diverse -- on the schedule were discussions about maker education, augmented reality, design thinking, game-based learning, coding in the classroom, digital storytelling, and many, many more! In an attempt to heed Dave Guymon’s call to share the ISTE learning (see his blog post on Getting Smart, "Don’t Leave Your Learning Behind: What To Do Now That #ISTE2014 Is Over"), here are some resources discussed by a group of elementary and secondary educators during a morning session on coding in the classroom.
