Slashdot videos: Now with more Slashdot!
1) ComputerCraft. Programming turtles in Lua and watching them go can be entertaining..
2) Pneumaticraft. Little arial drones (quadcopters) can be programmed using a very simple modular/graphical programming scheme.
3) Steve's Factory. The programming is more logical and less wordy, but the mod has a steeper learing curve.. and is a bit more boring as nothing moves around...
I battled with it on Far Cry 3. I still do not understand why I needed to login to UPLAY *after* I logged into Steam (where I played it from). Wasn't Steam enough of a DRM check for UbiSoft? 2 levels of login really?
AFAIK the original article was about someone who did not even install it correctly.. but still having to require it on top of Steam is just ridiculous.
In my work I find GSM carrier NAT infrastructure to be very annoying. Firmware running on the phone must be aware of a "use it or lose it" mentality in the carrier, in my experience this is usually around 15 minutes for TCP, then the NAT hardware flushes your route and it effectively disappears (breaking the protocol). UDP is even shorter.
In systems which must be bi-directional, this issue of keeping the connection alive is a concern, not so much for the phone but for the server which may be sending data back to the phone sporadically. It also forces the phone firmware to perform the initial connect, so useful server-based utilities are hard to put on the phone without modifying them.
IPv6 would (likely) provide a static IP address on the phone resolving all of these issues and providing better support for downstream communications from a base to the phone(s).
For all the kiddies reading this, realize that back in the 80's there were no readily available resource other than small electronic stores and mail order catalogs for young people to feed their interest in electronics. The material that Forrest Mims wrote was an invaluable resource into learning how design digital circuits using the new IC technology for that time.
I never made that flanger/phaser (audio effect) circuit though...
