The point of the various 100% solar, wind, battery projections that exist is that no new tech is needed.

Things won't be 100% Solar, Wind, Battery because other minor techs like nuclear, hydro, tidal, biomass or whatever already exist to some degree and can be part of the system. But current solar, wind and battery tech is enough, we just need to build it. The first 80% is the easy bit, with the greates payback, so there's no need to wait around.
Present biomass energy doesn't have remotely close to scale required to decarbonize ocean transportation. I'm sure the "advanced" part of advanced biomass assumes some mega-algae or something else that is far more productive than existing biomass, but if that technology hasn't been developed yet then you might as well just say nuclear fusion is the solution.

Hydrogen is currently produced via steam reformation [1], which emits carbon dioxide. Electrolysis is less efficient and corrosion of electrodes inhibits scale.

Nuclear maritime propulsion is far more mature than any of the alternatives. Submarines and warships have been using it for over half a century. Could a technological breakthrough create a better alternative? Maybe, but we can't move ships with potential technologies until said technologies make the transition from "potential" to "real".

The good news is that it’s very possible to “run the math,” and people run power generation capacity expansion models and production cost/dispatch models to look at these things. And then 15-25 years of solar irradiance and other weather data, at hourly resolution or shorter intervals, is available for most of the world.

Maybe the general public extrapolates from their own experience, but grid planners and researchers do much more than that.
It probably doesn't help much against a roach infestation, but fully automatic espresso machines make a good cup and keep the convenience. Ours was $1500 and has already paid for itself buying whole beans instead of k-cups.
boric acid is extremely effective. I use only boric acid, and i live in a forest. I put the powder under the stove, around the edges of cabinets, under the fridge, etc. After a new dusting (every 3-4 months or more) the carcasses will show up, maybe a half dozen.

And if you want a spray to kill insects you can see and watch, IPA (rubbing alcohol) and mint extract works fine. Except against centipedes.

For ants boric acid works sometimes, but so does talc or diatomaceous earth. However this stops them from tracking while you clean up whatever they're after. In my experience dealing with sugar ants, pissants, RIFA (fire ants from south america), fire ants (red ants in CA), and so on; the only 100% effective way to get rid of them is to put popcorn kernels in a blender and chop it till everything is smaller than 1/16" or so, and leave that somewhere moisture can't get to it. Ants eat it and bring it back to the nest to eat and then explode. I can't verify they actually explode, but that's the mechanism of action.

AFAIK boric acid and DE aren't harmful to humans, and corn and rubbing alcohol are usually fairly safe.
The number of discovered paleolithic burn sites easily ranges into the thousands.

Later occupation of a site wouldn’t change much - substantially different eras are easy to identify by relative stratigraphy, and fires hot enough for metalworking can typically be loosely dated by their archaeomagnetic signatures.

Quite simply, if you're stating things authoritatively, then you should have a source.
My experience was exactly the same. This is probably unfair, but I got the impression that the people who made Julia never actually.. used it? But of course that can't be true so maybe my work flow was just significantly different than theirs?

Not a fan of Python at all but now I just stick with that for my quant analysis. Tons of issues with Python too but atleast they are all known / well documented problems (also chatgpt knows pandas / matplotlib / python very well).
I'm pretty happy with https://www.mockplus.com
The picture I was looking for in the article! Thanks.
If it helps, even by 10 million LOC (assumedly most of which isn't unused legacy cruft) you're starting to dig deeply into templates and codegen instead of actual manual coding. I'm sure with all this AI stuff that will only get larger and larger.

But yeah, outside of some of the largest of FAANG software, there aren't a lot of codebases that can truly justify 100m lines of code. I'm sure GTA VI is over 100m lines but can be cut down to 10m if that was a priority (it never is)
Would you prefer PG&E defer critical maintenance on a field of solar panels or a nuclear plant?

That question dovetails into nuclear's biggest hurdle; the risk for catastrophe is high, both in reality and especially politically, so regulation is high, and thus the cost to build, operate, and decommission is immense.
I mean for the author's case you could go all the way and use CF Pages
The runtime I'm talking about is for the language that the JIT compiler is written in.

If I want to use a JIT compiler that is written in Java in my C++ game I now have to distribute the Java runtime with my game. That's an example of "not easily embeddable".
NRC missed one, eh? That's the thing with regulatory commissions, once you put them in you're never getting the thing done.

But we should always remember, regulations are written in blood.

But this is the classic technique of how to slow down something. Infiltrate by agreeing, and then kill it with committee. At least one W3C anti-ad group is currently hamstrung with this technique.

It's pretty good. And the best part is that the suckers you're exploiting will argue for you after a point because they'd have to justify why they couldn't get something done otherwise.

Yes! Another well-known program reducer is C-Reduce [0]. When Csmith [1] started churning out very large programs that exhibited errors in C compilers, the compiler maintainers asked the researchers to please reduce the ~81KB files to a more manageable size so they could understand the errors better. C-Reduce was developed specifically to address that need.

It's already 2-3 million +. Apple has amazing security, especially for the Iphone and continously monitors it and dishes out silent patches. For a REALLY high level example, it restricts system calls per process and requires all calls to be signed with an apple key, AND it restricts who you can do the system call to, these are continuously monitored and updated. Not only this, but persistence on Iphone is effectively dead, meaning you have to reinfect the device after every reboot. One of the big things you notice in the article is the use of ROP, apple requires every executable page to be signed by them, hence why you have to have these assfisting of rop chains.

It's true that it's hard to tell from the screenshots, but I'd say this game is way more non-euclidian than a mere "euclidian plus portals" kind of space. It's not simply the projection that makes it look strange, and there is no projection that can possibly make a hyperbolic world look like a normal 2d world. For example, a circle in hyperbolic space contains a lot more space than a circle in euclidian space with the same radius. If you want to get a better intuition for this, consider just trying the game.
Yeah, the safety standards for nuclear reactors exaggerate the dangers compared to the alternatives that are suitable for base load generation
Thanks, this is kind of on the path i'm also on.

A lot of entrepreneurial types are very much running around in the same circles jumping on the same trends and seeing life from the same perspective.

I remember being part of an incubator where there were 4 coffee distribution companies at the same time, pretty funny. Many others were doing online services for other tech people like some ouroboros.

At the same time designers and hacker types are often a bit introverted and isolate themselves with their work.

This creates a very deep disconnect between "the vast majority of people" that aren't very vocal online about problems, even more so the huge elderly demographic, but even zoomers are not tech savvy these days. So there should really be lots of opportunities out there if you don't focus on the tiny hot niches or techy spheres that so many people here target paradoxically.

Ie. combining "techy, nerdy or design skills" while forcing yourself out there is honestly a potential superpower - the other way around is not feasible for most, ie. the sales type learning tech that takes years and years to learn. Off course you can also always team up.
I love the concept of this game, very well thought and engaging
If copyright lasted 20 years like patents, it would be reasonable for AI companies to wait. 100 years is not reasonable.
Ironically: via the lens of ideas embodied by classical / full linear logic, there’s very elegant programming ideas the exactly correspond with the law of excluded middle.

This was my take as well, and I dont know how people who listened to the interview get it so wrong.

He basically described how you can make transaction fees or arbitrage fees on others engaging in speculation.

A very dumbed down example would how the post office can make legitimate income on postage while someone else operates a Ponzi by mail schemes. Or for that matter, brokerages take commissions when people trade meme stocks and unprofitable companies every day.

I see that one of the steps in exploit was to use GPU registers to bypass kernel memory protection. Does it mean that the vulnerability cannot be fixed by an update and existing devices will stay vulnerable?
to be fair, it's harder and harder to come up with an idea first. there's a lot of patents that have to be researched to see if your idea is first or just a first^Nth person to have the idea. that's a definite specialty skill and even then they're not perfect
I might enjoy a paid Haskell course, but thr site didn't seem to offer such.
Then go and get funding for it! Because apparently you know better than anyone else who was involved in defining this strategy. And given many, to domain experts, just hairbrained ideas get, or used to get, VC funding, it should be easy, right? And a tremendous market, just imagine what a hyper-unicorn one can build by having the monopoly on power the cargo vessels of the future!
They also say they are going to approve 6 to 8 more per year indefinitely.
Nuclear is renewable for the same reason geothermal is renewable, and you can get uranium out of seawater for the same price as mining it

The QR code, use, whatever isnt the problem to solve to. Its resolution.

This has always been a psychological issue with Humans and Signage.

Signage is a HUGE FUCKING DEAL (If you have ever had to some up with a signage policy for a Hospital with thousands of addressible spaces, where a certain population of 'stake holders' (nurses) are involved - getting naming/numbering correct in a large space where ALSO robots need to understand the convensions... that is south fast.

I have a bunch of solutions on this matter - if you really want to deep into coding... (I orignially designed a coding schema for Lucas Letterman which was shot down by the head of ILM engineering as "the worst Idea He had ever seen" to later incorporate that into his networking duties as head of networking at goog)

Anyway -- I am totally pro QR - but with GPTs, I feel like we are finally at the cusp to leverage them in a meaningful way.

(and for the downvoters - the schema I came up with for ILM was proposed in 2003, He didnt take the reigns at G until ~2008) - If GPT had been involved in some of my design projects- that would have been game changing, thus I propose that the most disruptable industy right now (aside from day trading) is construction.

Tons of models - but a model doesnt reflect real-world encounters/interactions/success...

(Honestly I dont know what to share, vs what to build.

realistic, but probably far from "optimal" (not that LoC is a good target for anything other than complexity). There simply isn't much incentive to properly refactor legacy code into something more managable. Rather eat the cost with devs ramping up and working around the cruft.
In this instance it seems you should avoid this habit.

Capitalized too, is that a new thing?
Yes. An example (in the associated paper) is to create a minimal reproduction of a crash so it's easier to debug.
I asked my optometrist about the best setting for viewing comfort, and she said black letters on white background. So I have that, except with a bit of tint, also following a theory that looking at certain colors affects moods.
Good thing that cube of uranium doesn’t need any extra space around it! We can just line them all up next to each other. Criticality accident? What’s that?

Clear cutting forest to put in solar isn’t likely to be cost-efficient. There’s plenty of shitty desert and mountainside land available.
This will not be neutral on Pizza Hut. The delivered price is their price.
The sellers’ goal is achieving a reliable income stream at the lowest cost, which dampens risk taking.

The buyers’ goal is to receive something which surprising and new, which means risk taking.

Trying to make balance both is the trick, and few media companies have the executives and management skills to pull it off.

This is a win for the environment and for human rights. A lot of people on here are talking about how solar and wind are better alternatives. The problem with that is that they typically need to be stored in batteries made of cobalt. The vast majority of cobalt mines exist in the Congo where modern day slavery exists to extract it. This affects everything from your Tesla to your iPhone.
The writing of the article was not as precise as it needed to be (I assume for the sake of saving space and words). It was a summary given in lay terms to an audience that could dig deeper into the source research results if they needed further clarification.

"After private equity acquisition, Medicare beneficiaries admitted to private equity hospitals experienced a 25.4% increase in hospital-acquired conditions compared with those treated at control hospitals. ... This increase in hospital-acquired conditions was driven by a 27.3% increase in falls and a 37.7% increase in central line–associated bloodstream infections at private equity hospitals, despite placing 16.2% fewer central lines."

I think it's fine and pythonic[1,2] to monkey patch when used in moderation and done explicitly:

I wouldn't do it as a side-effect of an import. Down that path lies Ruby. :-)

> answer to that is simple: powerlines, wind, hydro

Wind is still intermittent. Transmission and hydro expensive. The point still stands that marginal new power will become much more expensive before solar reaches anywhere close to sole source.
What makes the fear legitimate?
No AI needed. I use a custom code generator to generate 80% to 90% of the code I need in CRUD applications. And I can actually trust the code unlike code written by an AI.
We ran into a problem where we blew the direct memory limit recently.

To trace the problem, I added a breakpoint on ByteBuffer.allocateDirect() - this is how DM is normally allocated. But rather than suspending the process, we set it to print the stacktrace and continue.

This gave us handy output of possible causes. Focusing on the cases which were called from our own code (likely to be the root cause), we found a call to Files.readAllBytes() - which immediately sounds suspicious to cause a memory leak. Indeed this was the culprit, and explained why the problem was sporadic and hard to reproduce (there is some kind of per-thread caching behaviour of direct memory I never did understand properly).

Incidentally, Files.readAllBytes() uses direct memory because it uses an area of memory which both the OS can access (onto which to read the file contents) and which also Java can access (for the application code, rather than copying to the heap, which could be inefficient for large files).

Fortunately, this "by inspection" approach got us to the answer.

Others have stated profiling would work well. We'd have needed a local reproduction of the issue, which wasn't available at the time (could not reproduce without realistic workloads). Otherwise we could have used our SaaS APM software which runs in deployed envs, but that takes a sampling approach and doesn't really dig deep enough for this kind of stuff.
Batteries cannot feasibly achieve the scale required to even out diurnal, let alone seasonal, fluctuations. The amount of batteries produced is nowhere near enough to satisfy demands for grid storage, and it'd massively set back electric vehicle adoption. Even as battery production ramps up, it's mostly going to go the EVs. Furthermore, electricity demand is going to go up too as people move from gas heating to electric heating and combustion vehicles are replaced with EVs.

"No new tech is needed" is a pointless statement if it can't reach the required scale. You might as well say "just build more dams". We don't need any more wind or solar. Just build dams everywhere.

An open source approach to locally record everything you view on your Apple Silicon computer.

Note: Relies on Apple Silicon, and configured to only produce Apple Silicon builds.

I think the idea of recording everything you see has the potential to change how we interact with our computers, and believe it should be open source.

Also, from a privacy / security perspective, this is like... pretty scary stuff, and I want the code open so we know for certain that nothing is leaving your laptop. Even logging to Sentry has the potential to leak private info.
I mean, sure, but the parent should also just explicitly state what it is they were asking or claiming. I’ve answered every question asked. Making vague declarations about something not being “the benchmark,” while not stating what you think “the benchmark” should be, is unhelpful.

I've had Lockdown mode enabled for a few months. It's great, and not much of an annoyance at all. You do need to be fairly tech-savvy and remember that it's enabled, because sometimes something silently breaks and you need to opt-out of it (which you can do for a specific website, or WebViews within a specific app). And it won't auto-join "insecure" WiFi which can be annoying at a hotel, but frankly it's probably for the best. Also you won't receive texts with attachments in them, which is usually desirable but breaks workflows like activating a new SIM card while traveling (it's possible this was broken for me due to some other setting to exclude texts from unknown numbers).

The most noticeable difference is that SVG elements (?) are replaced with emojis. I'm not sure how that fallback works but it's funny to see buttons have seemingly random emojis embedded in them. (Does anyone know the details of how this replacement is done? Is it actually glyph fonts being replaced, not SVG?)

We used CloudEvents internally at Segment as an evolution of the existing ad hoc format that evolved naturally over time. We were generally happy with its ability to bring some semblance of order, documentation, and guidance to our event format while also being flexible to changes. For example, we layered on the ability for internal services to return 207 Multi-Status responses to batched events and it didn't require major hacks.

There should be a "roof-tile" mandated on every single structure built which captures weather information for every single structure. And that structure should be able to be read by any device which states in a standard format the sunlight avg per N, rainfall avg per N and temp.
