Re: Forum Shuffle

If further reorganization of the forums is still being considered, I would suggest "Windows 10 for IoT" be removed from "Other programming languages" and placed under "Other" in the Operating System Distributions section.

Re: Is it suitable? For a Computer Science course?

I would check with the university to see which specific computer system they need for the course of study and buy that type of system. Almost all computer science departments maintain computing labs which are suitable for doing the course work. A Pi would be good over the summer before attending. I...

Re: We're looking at introducing more swag - what would you like to see?

There's a guy somewhere on the forum asking if he should get his son a Pi for going to uni. He's going to need a key-ring, isn't he? Giving your son a bottle opener for the university may send the wrong message. I think an official Pi heatsink shaped into the Raspberry logo (along with a 3B+ to ins...

Re: A Extended Pascal Implementation : CONCEPT.

DavidS would not like it though, looks too much like C. You may be right.

Such a compiler would then serve as a resource for simple hobbyist projects and people using...

Re: What Does Hiding the Details of I/O in Library Calls Teach?

The Ion compiler can compile a million lines of code in a handful of seconds whereas GCC takes half an hour for similar input. The Bitwise project sounds nice. It is a little unfair, however, to compare the speed of a compiler which emits C code to a tool chain which creates linked optimized execut...

It's like the device is limited to 100mbit. Without working flow control the remote device sends packets at gigabit speeds.

Use the built-in 100 Mbit Ethernet or force the gigabit dongle to use 100 Mbit mode. The theoretical 3x speed gain with gigabit connected through USB2 requires working flow control and doesn't happen when simultaneously using USB storage anyway.
