Re:Ethereum Plans to Cut Its Energy Consumption by 99 Percent on Thursday January 03, 2019 @09:32AM (#18815316)
Criticizing cryptocurrency for it's energy consumption is absolutely ridiculous. Every step in technology requires ever increasing energy consumption... hell... the universe expects us to keep increasing complexity and energy consumption! Increasing entropy is basically our purpose...

And trying to decide what is - or isn't - a valid use of energy is pure arrogance. If anything, we should be arguing about energy sources...

I believe a simple moving average would achieve the same result and that mixing training and test data for validation invalidates your model results...

On a positive note, nice showcase of how simple implementation with Keras is.

Re:Stop treating tech jerks like gods on Monday September 03, 2018 @02:40PM (#17904207)
can we stop telling other people what they should do?

these tech giants are worshiped for what they achieve and how they transform the world, not for their flaws. And yes, they are flawed... they are not "perfect" like the instagram role models you follow - and live vicariously thru.

and using bill gates as a good role model is just laughable to anyone who knows just a tiny bit about his work ethics as Microsoft CEO.

Re:Centralized Wins. Decentralized Loses on Saturday August 25, 2018 @11:26PM (#17844067)
there's a relevant gap in his 'history of the internet' analysis where centralized web was basically all that existed for users (i.e. AOL walled gardens).

as many things in society, these internet trends seem to follow cycles of discovery/innovation and improvement/cost-efficiency.

and the same way the previous centralized web crumbled with the appearance of novel services, so will the current centralized networks. trust in innovation.

Re:Status – A Mobile Ethereum OS on Friday April 21, 2017 @02:21AM (#14163473)
I believe the issue here is not doing a hardfork. Hardforks are needed sometimes.

The issue is the purpose of "The DAO" hardfork (in practical terms, a bailout) and how it was done (destroying Ethereum's blockchain immutability).

Re:Ask HN: The most cyberpunk city in the world? on Thursday April 06, 2017 @09:22AM (#14050233)
Watching this documentary (https://www.youtube.com/watch?v=SGJ5cZnoodY) about Shenzhen I got a very strong cyberpunk vibe, especially the last 1/3 of it. People at the streets fixing electronics, cheap/pirated circuit boards being sold at the curb, etc.
Re:What If Evolution Bred Reality Out of Us? on Tuesday September 06, 2016 @09:45PM (#12440502)
I don't think they are talking about having NO sense of reality. They are saying that having filters that 'simplify', or make these signals more 'user friendly' bring evolutionary benefits in comparison to experiencing reality as is. In other words, we experience an altered reality sculpted by our cognitive engine.

This reminds me of Aldous Huxley's "The Doors of Perception", by the way.

I disagree with that. I have put more than one hour in and have found many interesting planets, creatures and geological formations. I'm also captivated by the small stories. What are the Sentinels? What and who am I? What's at the center?

Off course, it takes time and patience. Many worlds are barren, many creatures as very bizarre. But if you explore enough, you finds gems. And that feeling of discovery is something no other game I can remember gave me.

This game in fact is a different experience. I get it if it's not everyone's cup of tea (in fact, apparently the game was built to be 'divisive' [1]).

What I recommend for people beginning is to take their time. Leave their ships behind somewhere and walk around the planet. After you distance yourself from your ship (enough that the return trip on foot is not an option, the only option is finding a beacon to call it), you'll start seeing changes on the terrain. An unexpected lake, sand dunes, cave networks, forests where there were none, etc. The variety on the game is quite impressive, actually... of course, some patterns do repeat. But isn't that true for the universe as well?

It was meant as a sarcastic comment, of course it is inaccurate. :)

IMHO: Unfortunately democracy doesn't work, in practice, as the theory might suggest. What we have in the majority of countries are people in power focused on either: - Preserving their power (status quo), or tangentially the power of those who put them in office - Shifting the power structure, so that they (and their group) can take control

There are few and far between examples of politicians (let alone governments) that act with true altruistic purposes, favoring the interests of "the people". The built-in incentives in our society (and some might argue, our own nature) unfortunately make this a rare occurrence.

By the way... I might argue that the government doesn't sell our information because there is no buyer. It is the user of this information. It is used to control (mainly to control dissent). ;)

Isn't that the deal that Hector Monsegur (sabu) got?
Ah... these hackers just don't understand that hacking, invading people's privacy and stealing their money is a government monopoly.
Re:Ask HN: How to learn about the history of computing? on Tuesday July 07, 2015 @10:52AM (#9845792)
You can find some great resources (although more unstructured) on Youtube. I recommend the following: - Computerphile (https://www.youtube.com/user/Computerphile) - The Secret Life of Machines (1990's series)(some episodes touch on computing - https://www.youtube.com/watch?v=gOULWR4h4Io)
Re:Brazil's gamble on deep water oil on Wednesday July 01, 2015 @10:26AM (#9812005)
compounding on the other responses, the increased emissions of CO2 in the atmosphere are also changing the ocean's chemical properties (acidification).. and this has a huge impact on the environmental equilibrium. https://en.wikipedia.org/wiki/Ocean_acidification
If capitalism is as good as they say, BTC entrepreneurs and miners should be pouring money into cleantech anytime now ;)

The second point is something I've asked myself without any clear answer. Interested too learning more about this.

Re:Telegram Bot Platform on Wednesday June 24, 2015 @06:21PM (#9774880)
Thanks for the reference! I've seen some implementations (https://github.com/asdofindia/python-whatsapp-bot) but usually Whatsapp bans accounts that do it.
Re:Telegram Bot Platform on Wednesday June 24, 2015 @05:46PM (#9774708)
I believe this an amazing move by Telegram. I firmly believe that open platforms tend to win in the long run.

Whatsapp should take the hint and open up their platform for developers... Curiously I was thinking about building bot-based services on their platform (largest user base in my country), but basically gave up after seing how closed they are to any initiative like this. Felt even worse after reading things like this: https://twitter.com/gcmartinelli/status/605776036358291456

Re:A Brazilian Wunderkind Who Calms Chaos on Thursday August 14, 2014 @12:50AM (#8176144)
I was actually surprised at the coverage, at least in online newspapers. There hasn't been any coverage on the first woman to win the prize, though...
Re:Ask HN: My industry's becoming commoditised and I'm scared on Wednesday February 19, 2014 @12:28PM (#7264754)
Could you please source some of the reports that talk about the automation of the workforce? I agree with the gist, but I lack sources to defend the point.

Ask HN: Can 'hackers' live outside soft/hardware?

What does HN think about definitions of 'hackers' that say the term can be applied to anyone who circumvents a specific system (be it online, physical or even conceptual like politics)?If such a definition is accepted, what are some examples of hackers 'outside' technology, or at least outside computing (ex: Wright Brothers)?

( Read More... | 6 comments | 5 points | on HN )
Sure! Pretty simple actually, running on GAE. Using jinja2 for the templates and some custom bootstrap for the frontend.

I plan on writing a bit about what goes on at the backend. I built some features I had never tried before (URL shortener, social integration, simple analytics). Maybe I'll open source part (or all) of it.

It won't impress any pros, but for a beginner I believe it's a great step forward, and my experience might help others. :)

this is my most recent personal project.

I built the platform from the ground up, a great learning experience for a beginner like me.

I would appreciate any feedback you guys have! Thanks!
