The good thing of people using for small problems overkill queue systems like Kafka or RabbitMQ is that they usually have time to react and correct the mistake after burning lots of engineering resources. The sooner they make the mistake, t

How much latency does it add?

Kudos. The most interesting thing in smartphones for my needs since the Nokia N900, not counting the SailfishOS efforts. I'll buy one if it works "a la Maemo" (Debian derivative).

Yes, that's how works the RB-tree example I linked. However, it is much harder doing that for implementing tries, except if you work only with the full node case, which would imply wasting a huge amount of space. At least, from my expe

A good point for both RB trees and linear-addressing hash tables is that they can be implemented with vectors( [1], [2]), allowing the case of initial reservation for N elements, so with a tricky implementation you could even have the data

Pine64 is ok, at least with Debian 8 (no hw video acceleration, fine for doing ARMv8 tests/builds).

I would love ARM releasing ARM1 and ARM2 processors (both with a 3-stage pipeline) for FPGAs, not because of economical interest, but because of historical and coolness purposes. And more, so you could e.g. run a synthesized Acorn Archimede

As contrast, calling C from Python, even using callbacks, it is very easy and incredibly useful, thanks to the "ctypes" [1] [1] https://docs.python.org/2/library/ctypes.html

Probably not using a Java VM, but a Minecraft-like game would be doable e.g. using GNU gcj (Java to native code). E.g. the PS2 (32MB RAM + 4MB VRAM, 294MHz R5900 2-way IoE w/ SIMD + 2 x VLIW VUs @294MHz, with massive fillrate capabilit

How it can be that inefficient? It looks like a monopoly or corruption. In Europe medical costs are way lower (not what the user pays, but the actual cost).

Intel already made an important effort regarding being Open Source friendly. In my opinion they should keep playing the nice guy role, avoiding PR fiascos.

May be the "Roman horse" here is that BGR is RGB in little endian format. Also, it has lots of advantages: little endian pixel handling allows using similar code for 24 and 32bpp (rr.gg.bb.rr.gg.bb vs rr.gg.bb.xx.rr.gg.bb.xx), so

Intel CPUs without firmware updates because of redistribution limitations? How can Intel make that mistake? Intel, please, reconsider that, for your own good.

"up to 160 million operations per second" Read operations? Write operations? Per core, or using N cores? For the case of one core at 3GHz, it would mean 20 CPU cycles per operation, which is barely enough for storing the data in t

But it is not Open Source. There are more commercial products using FPGA's for emulating gaming console hardware.
