carlosedp··on Learning Verilog and FPGA
I started playing with FPGAs and HDLs a couple years ago with no hardware design background (I'm mostly a software architect/engineer) and in the end found that a "higher-level" HDL suited me better.

I chose Chisel (https://www.chisel-lang.org/) an HDL based on Scala (technically a Scala DSL) which can provide many facilities to hardware generation.

I'd highly advise looking into it although also knowing Verilog helps a lot.

carlosedp··on Debian Riscv64 port in mid 2019
The Unleashed board has a performance similar to a Raspberry Pi 3 in cpu terms but it's biggest bottleneck is that the SD card is running on a SPI bus where it gets something like 2MB/s. This is due to having the complete SOC as opensource and the SD card association not allowing open source IP for it's interface.
carlosedp··on Arm Announces Client CPU Roadmap For Laptops
Here is a simple benchmark comparing a Linux VM in my laptop with 2 cores, 4 cores and the RockPro64 board. On the SBC section I've put the power consumption during my tests:

Fantastic for a $80 board that consumes less than 10W.

According to the post they fetch from Foursquare API.
carlosedp··on LG Smart TVs log USB filenames and viewing info to LG servers
Actually that's not necessary. I have XBMC installed into an old Macbook that uses the Apple Remote perfectly. Their usage fits into A.R. layout and buttons.
carlosedp··on LG Smart TVs log USB filenames and viewing info to LG servers
The Apple remote is exactly the remote that came to my mind when I think simplicity. That's what most people use. up, down, left, right, center(for enter/go/confirm) and a menu (for options, back).

Thats 99% of a remote usage, the rest is handled by any GUI.

carlosedp··on Ask HN: Had someone switched back from SublimeText?
Tried Sublime a couple times but I always miss something from VIM. Switched back. No patience/knowledge to customize Sublime the way I do with VIM.
carlosedp··on Python trademark at risk in Europe
EVE-Online, a big MMO uses Python for it's servers and clients and they even contribute to Stackless Python source. They are in Iceland. Maybe you could try contacting them.
carlosedp··on How SoundCloud built its new single-page main website using Backbone.js
This is exactly the approach I'm doing. I'm writing the app entirely server based, just a couple of ajax do avoid loading unnecessary data at some time.

The time I finish the app, I will tweak and optimize loading either by AJAX or implement something like backbone views.

carlosedp··on How SoundCloud built its new single-page main website using Backbone.js
Do you share the same templates between server and backbone? I'm trying to escape code duplication as much as I can.

Do anyone knows any pattern to have the server templates sent to backbone avoiding duplication?

carlosedp··on How SoundCloud built its new single-page main website using Backbone.js
How this goes against the recent Twitter move to return rendering to the server? How to find the right balance of client and server functionality?
carlosedp··on Ask HN: Buying new MBP this weekend. After market SSD recommendations?
I'm about to add an SSD to my 13'' MBP and put the current 320GB into OWC's data doubler (replacing the DVD drive).

I will go with OWC's Mercury 6G 120GB SSD. But still haven't decided between Electra and Extreme.

carlosedp··on Ask HN: Which one should I learn deeper, Node.JS/Express.JS or Ruby on Rails?
Actually I`m thinking about what could I build myself... maturing some ideas but in the meantime, I'm been looking at the market if there are opportunities for me to move and work in USA since I'm from Brazil.
carlosedp··on Ask HN: Which one should I learn deeper, Node.JS/Express.JS or Ruby on Rails?
I thought the same about Express the beginning but as I learned my way thru it I found it very simple indeed. You can build a Web App on a couple lines and never worry about protocols and stuff. Easily integrated with Websockets using Socket.io too.

About Rails, I think that seems like there is too much happening behind the curtains with magic. Express seems more objective.

carlosedp··on Ask HN: Which one should I learn deeper, Node.JS/Express.JS or Ruby on Rails?
Maybe you are right. Recently I've been playing with Node and some of my recent projects (they are on http://github.com/carlosedp ) are made with Node.

Also, every time I think about learning Rails deeper I think "damn, I already know how to do this on Node. Why bother..." but the industry wants Rails experience and every Rails developer I read loves it.

That's where the question came. Should I go with the current market or should I invest in a "promise" for the future?

São Paulo here too.
carlosedp··on Top Programming Fonts
Very nice font. Just replaced Vera Sans Mono with it on my VIM configuration. Great tip.
carlosedp··on PyPy 1.5 Released: Catching Up
Nice, the CCP guys are great maintaining Stackless... Kristjan and Richard do a great job on it. If there are any clues or tips on how can I help out, it would be a pleasure.
carlosedp··on PyPy 1.5 Released: Catching Up
Fantastic... Christian worked hard on Stackless and I think it`s a great feature. On Pypy it would be easier to maintain and add functionality, unfortunately, I struggle on Stackless internals and it`s low level C gimmicks so I can't help on it. It would be great to have something like a good framework in the future to make it`s adoption easier. We have the Stackless Examples project to address this initial learning curve thing. http://code.google.com/p/stacklessexamples/
carlosedp··on PyPy 1.5 Released: Catching Up
I wonder how hard is the integration of Stackless and the JIT features. That would be killer.
carlosedp··on The Little MongoDB Book available on GitHub
Congratulations for the book, also for using simple and effective publishing tools like markdown and Pandoc.
carlosedp··on Give HN: Free project/startup idea. Please make this.
Exactly, the Google Reader does its job pretty well and the most important thing is that if I read something at work, I don't have to skip the same post at home. Google Reader and native clients that integrates to it like Reeder are fantastic.
carlosedp··on Pypy wants you - now's the time to start contributing to Pypy
It would be great to have the JIT and Stackless features together.

carlosedp··on PyPy 1.4: Ouroboros in practice
I hope they add support for JIT with the Stackless features.
carlosedp··on Python-on-a-Chip now supports Arduino Mega (BlimpDuino, Robotics, Touch Screens)
I saw that Stackless threads can be run, It means that the actual Stackless Tasklets (http://www.stackless.com) can be created? Any doc about the implementation?

Is the capsule reuseable? It looks pretty beat up from the outside.
