There are people who are alive today, and who won't be next year because of extreme weather events tied to climate change. And that's before getting into real live issues to do with water rights, habitation, crop resilience to changing weather patterns, energy access and usage. These issues are likely to spark wars in our lifetime (if they haven't already.. Syria and the Arab Spring was tied to crop failures and high…

I'm not sure this is true, at least not on net. Do you have any scientific evidence showing a net global increase in extreme weather events in the last several decades?

Have you even looked out the window, lately?

> The most pressing problem for humanity is global climate disruption. Our climate and ecology are certainly at risk, but I think the biggest threat in the world right now is the rapid rise of fascist China. They're challenging the notion that free speech and democracy are required for capitalism and economic gain. China has grown so emboldened under President Xi that they're no longer content to just alter or buy ou…

Exactly.

The most pressing problem for humanity is global climate disruption. Arguably, working on anything that doesn't help there is not just wasted effort, but actively harmful. Wind, solar power, energy storage still have huge room for improvement. Direct solar or wind -> liquid fuel will be essential to adapting fast. Windmills can drive production of liquid ammonia on farms (needing only air and water inputs), for use d…

HFCs are already being phased out in favor of HFOs (though you could certainly argue that this should be happening more quickly), is there a strong reason to go for ammonia based systems over HFO?

Thank you, the atmospheric half-life of HFOs is short enough to make it a viable alternative to ammonia as a refrigerant. However, the existing stocks of HFCs, in installed systems, is enough to match, if vented, the heating from all the CO2 currently in the atmosphere.

There really isn't, any more. A few more polys in the models and a few more rays in the path tracing aren't a big difference. Check out what Blender can do with Eevee, which is more-or-less a realtime engine. Better physics simulations are still a big differentiator, but that doesn't matter for characters. The only reason rendered likenesses don't appear in films more (because they already do, look at Peter Cushing)…

The CGI Peter Cushing is obviously CGI and non CGI Peter Cushing is obviously not. Its impressive but its not remotely close to being there yet. Is there a better example? You can probably make some CGI stills that fool people pretty well, but so far I haven't seen a convincing animated character. Death Stranding is even more glaringly obvious. However to be fair to the devs they aren't under the impression that it l…

> CGI Peter Cushing is obviously CGI and non CGI Peter Cushing is obviously not.

It's interesting you say that, because I've found there are two camps of people on CGI Cushing: those who say the CGI is blindingly obvious and nowhere near realism, and those who didn't even notice. It is already good enough to fool some of the population.

I'm also not saying Death Stranding is photorealistic--unlike Tarkin it wouldn't fool anyone. I'm saying there's nowhere near an "ocean" of quality difference between the best video games and film CGI. Death Stranding isn't an example I'd use because it runs on PS4 and thus lacks the raytracing and high poly counts of state-of-the-art PC games.

I work in this field so I'm incredibly biased: automated business solutions that cut entry-level data employees out of the equation. You save TONS on the bottom line, and cut out human-driven process that is error prone and difficult to manage. I'm talking about things beyond "API-driven dev", more in the realms of Puppeteer, Microsoft Office automation, screen-scraping (mouse/keyboard), etc. I make API's out of thin…

The key to these types of solutions is always to follow the 80/20 rule. For example, it’s foolish to say and attempt “I will automate all of your data entry people” because there will always be weird idiosyncrasies that are better fit for humans. You will dash yourself against the rocks trying to get a “100% complete” solution. Instead, create software that allows 1 person to do the job of 5. You create massive busin…

How do you guys network with the right business people to speak their language and find out how their processes work? You need that info (a problem description) before you come out with a solution, don’t you?

Just ask. People absolutely love talking about their problems, it'll probably be the most animated thing they have to say about the business they're in.

"Some people profess difficulty at finding applications to write. I have never understood this: talk to people. People have problems — lots of problems, more than you could enumerate in a hundred lifetimes. Talk to a carpenter, ask him what about carpentry sucks. Talk to the receptionist at your dentist’s office — ask her what about her job sucks. Talk to a teacher — ask her what she spends time that she thinks adds the least value to her day."

Not sure what more recent xboxes are like, but the original xbox was a cut down windows 2000 running on Intel and Nvidia. It was really close to commodity hardware and software.

the current Xbox is running a Windows 10 (one kernel design) while the PS4 run a patched up FreeBSD. Only Nintendo bothers with writing custom kernels, and historically Sony with the PS2 having exotic "Cell" processor units.

The Switch also runs on FreeBSD, not custom.

It is true. "New data show that extreme weather events have become more frequent over the past 36 years, with a significant uptick in floods and other hydrological events compared even with five years ago, according to a new publication" https://www.sciencedaily.com/releases/2018/03/180321130859.h...

In the online world, it seems like there are two big things happening right now: - Neural networks / ML (eg GPT-2) Definitely nowhere near its potential for being applied to a wide variety of areas. Find a niche you like and apply there. - Security / Privacy (eg Telegram) Rapidly growing demand pretty much everywhere. Bonus points if you can make your product great for standard users and at the same time hackable/cus…

As someone using ML in production at scale, it's not the sophistication of the models themselves, but all the "boring" operational stuff around them. - Keeping them fed with clean, high quality, low latency feature data. - Understanding the impact of an ML intervention on the overall system or business process, in aggregate and for all the relevant subpopulations. - Understanding why scores may be drifting. These are…

Such ridiculousness in posts like these. You want to stop climate change? That effort needs to include China and India, which between the two, are good for much of climate changing exhausts. You want truly renewable energy, with high yields and limited need for resources, go nuclear. Oh that's right, our climate zealots, who would have you punished for using your internal combustion engine auto, are afraid of nuclear, so that's off the table. Is climate change real? Yes. But stop with the sensational Green New Deals and the banning of air travel and such. Start with China and India.
