Em reacção à enorme quantidade de votos nulos nestas eleições nos votos por correspondência (outra vez) porque os eleitores não entendem o processo de votação, aparece um delegado a dizer “é por isso que o voto eletrónico é urgente!”

Ora, eu fico que é precisamente prova do contrário:

  1. então o estado ainda não conseguiu implementar o voto por correspondência de forma funcional, e achamos que vai conseguir implementar um sistema de votação que tem um grau de complexidade de uma ofdem altamente superior?
  2. os eleitores não percebem como funciona o sistema de voto por correspondência, e vão entender o desenho de um sistema de voto eletrónico?

Maybe you’ll enjoy this as well:

I still have one of my first modems, a Creatix LC 144 VF:

Image

I think this was the modem that I used when I first connected to the internet, but I’m not sure.

I plugged it in again and it still works:

Image


Image

The firmware appears to be from 1994, which sounds about right. I don’t think we had internet access before that. We certainly did use local mailboxes, though. (Or BBS’s, as you might call them.)

I now want to actually use that modem again. For the moment, I can only use a phone to dial into it, I lack a second modem to actually establish a connection. Here’s a video:

Image

Not spectacular, but the modem does answer after me entering ATA.

I bought another cheap old modem on eBay and am now waiting for it to arrive. Once it’s here, I want to simulate an actual dial-up session, hopefully from OS/2 or Windows 3.x.

↳ In-reply-to » Over the past few weeks I've been experimenting with and doing some deep learning and researching into neutral networks and evolutionary adaptation of them. The thing is I haven't gotten very far. I've been able to build two different approaches so far with limited results. The frustrating part is that these things are so "random" it isn't even funny. Like I can't even get a basic ANN + GA to evolve a network that solves the XOR pattern every time with high levels of accuracy. 😞

This is one of my attempts: 

$ go build ./cmd/xor/... && ./xor

Best network performance:
