As far as I can tell every top level comment in this thread claiming that Nuclear is more expensive than wind/solar is simply wrong.

-- First of all, complaints about the capex of nuclear make little sense if you are trying to argue for wind/solar; as the only reason you could plausibly make a case that solar/wind enjoy a comparable marginal levelized cost as fossil fuels is assuming that the cost of capital is insanely low thus making the large upfront capital expenditures on solar/wind infrastructure look like a better tradeoff than the cheaper upfront cost of fossil fuel and higher ongoing maintenance/fuel to run a fossil fuel plant.

If you are making that assumption for wind/solar it stands to reason you can make the same assumptions for nuclear as well. Of course, in the "real world" only super rich countries can afford to make those tradeoffs in the first place and given that nuclear usually requires access to cheap capital (i.e. government loans) it stands to reason wind/solar have the same problems; and to use an example I will return to later Germany has considerable subsidies for wind/solar compared to fossil fuels as expected.

-- Secondly, no utility uses the marginal cost of producing electricity for a power source that is inherently variable. The economic costs of failing to produce enough power for a regional or national utility outweigh any hypothetical marginal advantage for wind/solar. Essentially every wind/solar power source has to have a reliable backup source that can step in to ensure the utility can meet the demand for electricity. In most cases this just means you build cheap combined cycle gas plants. If you are a rich country like germany you can afford to overbuild your power generation capacity.

Countries like germany also have the advantage of being able to purchase energy from neighboring countries to make up shortfalls in demand. The german energy program relies on the availability of french nuclear power for precisely this reason. Of course, some days you can trumpet that some gigantic % of total production is supplied by wind/solar but this is mostly irrelevant from the financial perspective of the utility.

-- Finally, energy storage for wind/solar simply doesn't make sense with current technology. To take one example, Hydropower can already be expensive; now add in the cost of producing enough renewable energy to power all the original power produced by hydro cycle AND the cost of machinery to somehow replicate the operation of gravity. Basically you are looking at 2.5 to 3x the cost of your original investment to make your variable energy source reliable. Current lithium battery technology is totally unworkable at scale as another alternative.

To top it off I think the levelized cost figures often trumpted on this site for wind/solar are off anyway. Basically, unless you get a bunch of subsidies from the government it almost never makes sense unfortunately.

I was commenting on the effect the renewables would have on running the grid itself. In general, the grid seems to be able to handle to increases in renewables we've seen so far and those we see coming.

CommonCrawl already has open dataset in petabyte size ready on AWS. Even if it didn’t exist, scrapping 80GB of data in AWS is trivial. I am surprised authors considered this as such a big deal. Also notice that performance is not anywhere close to humans. It sort of works and it’s astonishing that it does but long way to go before we have to fear weaponizing text generation.
A better system would be to offer buyout of the panels when the house sells.

For example if they decide that the system needs to be bought for 20k when the house gets sold, then when you want to sell your house you just bump the price 20k to account for the panels buyout.

There, no lien to the home, and no confusion from the buyers thinking they get a house with solar panels when they're just getting a house where somebody else's panels are installed.

From my own subjective experience:

DO has huge reliability issues, particularly in NYC. Over the course of several months I had repeated brief network drops on random VMs (during EST business hours, lasting up to a couple minutes). Their object storage in NYC3 (only location at time I used the product) would constantly drop uploads of larger files (experienced in multiple locations behind different firewalls, not environmental) and was also down for several days at one point not too long ago.

Perhaps things have improved, or my experiences with roughly 20 VMs distributed between Toronto and NYC was abnormal given the overwhelmingly positive sentiment in this thread but I figured I'd offer my $0.02 if only to play the contrarian.

Yep, you can't put the genie back in the bottle.

If you successfully tested a nuclear weapon it would be incredibly naive to think you could save the world from nuclear weapons just by keeping its implementation secret, someone else out there is just as smart as you and once you've proven it's possible then it's just a matter of time before someone else figures out how you did it.

You're right to ask, it does not. In the FOSS world the license of the compiler has nothing to do with the license of the compiled software, and that also goes for the GPL 3.

>> The levelized cost of wind and solar is already cheaper than nuclear. They can be brought online in months rather than years, they can be deployed at whatever scale is needed and we can use market forces to do so.

I'm not personally aware of any place where this is actually true.

Even assuming you are not building out wind and solar on the scale of a country like germany you still need comparable subsidies to incentivize power producers to build new renewable energy sources; to say nothing of the grid management cost. You can quibble with exactly how large the subsidy is and, to be fair; unless you are employed by a consulting comapany you will never have access to the internal accounting figures that actually value the marginal cost of electricity produced by variable renewable sources compared to conventional sources but the subsidy is almost certainly not less than 15-17% of the wholesale price. Given that this subsidy is guaranteed by law to extend far into the future it simply defies imagination to assume that the levelized cost is somehow comparable at all.

I see this kind of argument a lot and a fair number of times someone claims they work in the energy industry or at a think tank with renewable energy or something. If that is the case I find it strange that they can't name actual examples where wind/solar don't require subsidies. It's usually just a link to a Lezard report with strange CoC assumptions.

Of better, you want to display the ranking to each user if there are multiple quiz.

So, they never say this is near flawless, or that it would fool you in a turing test. In some contexts though, it may be usable maliciously.

Yes, refusing to do things that are technically bad is a technical matter hence a developers job. And what happens if you say no, they either go find a developer who will do it (seen that so often) or they go to the CTO/Engineer Manager/etc to try and get them to agree. In both cases, a developers job is to give technical feedback such as "Sorry but that's a security threat, you'll need to figure a new approach. Maybe try Z." not, "I think it is a better idea to work on X instead because it's going to generate Y". One is technical feedback on their idea and the other is a product/business idea.

> Expanding out of a strictly coding role isn't just good for career progression, it's a necessity for career self-preservation, too.

The first part is pretty much my point. To progress in a career in IT you have to stop doing technical work to progress. Development is a dead end job, just a reasonably well paid one. The second part, for the most part, I've never really seen. Most developers I've worked with haven't been held accountable for anything in such a long time that they get offended when you point out 500 servers going down in 20 countries because of one Redis server is embarrassing and we should work on stopping that from ever happening again and give excuses why it's not.

Yes, exactly. Life is a marathon and if you put in consistent effort you'll make it to the "finish line". Perhaps slower than some others who had more time to move more quickly or with significant breaks, but you’ll get there.

Maybe a polarizing opinion, but if you put yourself in a box that “doesn’t have enough time” just because you have a commute, are a parent, [insert other excuse here], then it’s the equivalent of sitting at the start line and watching everyone, even the walkers, tread ahead. It's okay if that's what you want, but it is a choice.

Delphi was my first exposure to a real programming language almost 20 years ago. I'm very glad that it was it as I look upon the landscape of software engineering nowadays and it's totally opaque to beginners.

Delphi has right abstractions in a right place - you designed the form in a easy GUI and filled in methods with your code [0].

Why it was that way? Because it was designed to be simple and it worked (no need for Bret Victor's magic). (There was a blog of former Delphi developer that explained their thought process)

For the record I worked professionally in JavaScript (TypeScript) (backend and frontend), Java (Kotlin), C# and Ruby. I also did small chunks of support code in C/C++, Rust, Red/Rebol, Python, PHP, Go, Prolog and Lua.

If I wanted to teach kids programming today, something easy to understand but at the same sufficiently complex I'd probably choose Delphi (Lazarus looks like Delphi 5/7 from screenshots).

I'm a more casual developer just to put that out there, but I'm Australian. Since this law came out, I have definitely lost a few contracts. Eg you can see in their eyes when they hear my accent. Yes it's just from my point of view, and I'm probably also shaking more birds out of the tree than really exist, but it's my belief.

Irrespective of that view though , any Aussie programmer who lives abroad(such as myself), have to consider what would be waiting if we visited family and friends.

I can honestly say I'd make a stand, screw the consequences, but what about everyone else? I'm a headstrong bastard(too much haha), but others have families to consider (I do as well, but my wife supports me on this position).

I moved to Japan for my wife, that doesn't mean we planned to stay here forever, while I do want to now, I know quite a few Aussies here that want to return eventually.

What I remember most fondly about the Borland stack was how well it abstracted away all the messy Windows 3.x and 95 UI code and made working professionally as a Windows dev much less stressful.

Also, for a time, it totally blew away MS Visual C, although the VCL was hella inconsistent, and that was rather maddening at times.

To be at max productivity you had to scour the web looking for snippets that showed you how to, say, add strings to this widget or draw on that canvas.

The RAD implementation was rather brilliant, and for several years at least blew its main competitor, Visual Basic (ugh) totally out of the water.

Additionally, they are audited externally, currently by Norway. Although I'm not entirely sure what would happen if they were to fail an audit.
