35 - lately i've been learning about arcade machines. how they work, how to fix them, etc. Ive fixed two so far back to perfect working order. My next project is a small repair on a EM(electro mechanical) pinball machine from the 70s, kinda of excited about it.

#11246, I took Discrete Math I & II this past spring. It wasn't easy. Last math class I has was (failed) Calculus I in 1989 and (failed) again in 1990. I got a B+ and an A- this time, but I probably put in 30 hours per week studying and doing homework.
Just out of curiosity as I'm probably closer to your age than I am to the majority of folks here, are you taking these classes as part of a grad program in CS or related?

Undergrad. I never completed my degree so my manager (and his manager) encouraged me to go back to school and finish...especially since they are paying for it.

#11731. In Java, this code can spin forever if a different thread changes this.done, and it's not a "volatile" member. while(!this.done){ Thread.Sleep(1000); } The more I learn about Java, the more I'm shocked at how mostly-identical it is to C#. Except C# is clearly superior in the details. I expected to find something java did better, but I'm coming up short.
One interesting article I read had an interesting point: one thing Java does better is to use type Erasure. This was surprising to me because reified types are often touted as one of the best things about C#. The author's argument was that type erasure made implementing different type systems on the JVM easier, because type erasure isn't as strict, which makes the JVM a more attractive language target than the CRT.

#11821. Just started going through the K&R text to learn C, it's definitely helped some aspects about programming that I didn't get in my Java courses. Also doing it exclusively in vim so I can practice typing and making sure I learn a lot of vim and terminal commands.

#12044, a former coworker that I would go see once a year at a coding conference just passed. He was 47 and left behind a wife and three young daughters.
I learned never to take today for granted and don't put things off for tomorrow with your loved ones. Your job will send flowers to your family and then open up a req for your position. Don't put your job before your family.
