If you read the link you'll see that they found out go forces a GC every two minutes no matter the amount of garbage.

virtualSatai··on The Real Value of $100 in Each US State
I'm in no means an expert in this, but I think it's because of the relative sizes of the economies in each state [1]. California and New York are very large in terms of GDP/GSP and will therefore move this weighted average accordingly.

Wouldn't it make sense for the BBC to sell their service to people outside of the UK? Aren't they allowed to? Or do they already?

What's your specs/browser? I get: http://i.imgur.com/dtKCSxL.png in Waterfox 40.1.0, and http://i.imgur.com/4bu0Hev.png in Chrome 47.0. 20x and 26x improvement over the slowest.
virtualSatai··on Show HN: PJON_ASK – Radio multimaster communications bus system for Arduino
Isn't https://github.com/gioblu/PJON_ASK/blob/master/PJON_ASK.cpp#... sufficient?

Internally RadioHead and VirtualWire uses a 4to6 bit en-/de-coding. Their reasoning is that if your payload is either high or low for too long, "for a good DC balance". have you experianced anything related to this? You but in 0b01 padding before each byte, maybe this is enough. Your solution is substantially lower overhead.

You speak a lot about VirtualWire, this is no longer used. It was been replaced with RadioHead. There are no significant feature differences, afaik.

I'll try this out tomorrow, using say 5 Arduinos with 433 MHz radios.

What antennas do you use for the radio modules? We've used quarter-wave monopole of 17.3 cm on both the receiver and transmitter with some success.

virtualSatai··on Elon Musk Had a Deal to Sell Tesla to Google in 2013
I'm pretty sure it has been seen before that Google or another big tech company buys a smaller up-and-comming company/great idea, and it is never heard from again.
virtualSatai··on Tupper's Self-Referential Formula
You have a pixel grid of 17 x 106, anything you want to drawn in it can be.

To draw an arbitrary figure do this: Start with the pixel in the lowest left corner, if black put 1 as the first digit of a binary number else put 0, then continue first up then one right, the down. Convert this (1802 digit) binary number to decimal and use it as input for the function and there it is.

virtualSatai··on Simple CPU
The gates with the simple toggle functions are really good and simple to use. It reminds me of playing around with redstone in minecraft.

Knowing most if not all of this already I cannot say how well it teaches, but it does describe what I spent much longer on learning.

They already have ReSharper, that combined with Visual Studio is pretty good.

This is a good concept, and executed well. What is the backend and is this open source?
