Utility scale renewables are in pennies pwr kWh in Levelized Cost, and continually dropping.

There are 10kWh/liter of jet fuel. Utility scale solar is 3c/kWh LCOE today.

Assuming a pessimistic 10% efficiency in electricity to synthetic jet fuel conversion via H2 hydrolysis and the Fischer Tropsch process, that's a hypothetical $3/liter of synthetic jet fuel.

Current petroleum based jet fuel is $1.50/liter.

If you improve the conversion efficiency to 20% and lower the LCOE of utility scale solar to 1c/kWh (projected by 2050), and the hypothetical liter of synthetic jet fuel drops to 50c/liter, all while petroleum jet-fuel grows increasingly scarce and more expensive.

The efficiency of synfuel production could rise significantly as the efficiency of feedstocks like H2 hydrolysis (already 50%+) increase, and if if CO for Fischer Tropsch can be sourced from biomass instead of sourcing it from atmospheric CO2.

Finally, it's likely that in the future we'll switch to using hydrogen directly as an aviation fuel, bypassing hydrocarbons altogether, at which point the electricity to air conversion efficiency nears 80%.

At those prices, you can begin to afford to overbuild renewable capacity to drive a synfuel pipeline to store that energy chemically, which we will arguably need to do for seasonal energy storage anyways.
No. No, no, no. Well, maybe. I mean, sure, of course. I mean, I guess that's right. So, yeah. Yes.

The problem isn't just faking a stack with a fast buffer, it's figuring out where the sources are, or rather, will be, with pipelined execution, or worse yet, decoding multiple instructions at once.

You also want to have multiple instructions writing a given architectural resource live at once. That's tough if top-of-stack is a buffer location.

> Calories in vs out is wrong because those who tote it assumes that only physical exercise has an effect on calories "out".

No, they actually dont assume that only physical exercise has an effect on calories burned. In fact, CICO is agnostic to the means by which calories are burned.

> This is why just restricting calories in and exercising more won't necessarily mean you loose weight.

Actually, so long as you burn more energy than you consume, you will lose weight. Again this is agnostic to how the energy is burned. What the body does to adjust is merely effecting the amount of energy burned. It does not effect the formula concerning CICO.

I didn't know it was a Rails project, though I suppose it makes sense. That's neat.
I'm guessing they weren't sure whether caste was a protected class.

Discrimination in law revolves around protected classes (race, religion, national origin, age and sex are the "big five" in the US, and subsequent acts and decisions have added sexual orientation/gender identity, familial status, pregnancy, disability, veteran status, and genetic information). If you act on the basis of that, someone can, well, make a federal case out of it.

On the other hand, if you discriminated on the basis of eye color -- pretending for a moment it wasn't correlated with race -- you might be a shitty manager, but it wouldn't be a legal issue.
Computing has been retreating off the personal & away into the cloud, to neo-mainframes. It feels like the revolution gets further off.
No, there are not. (In the USA) You are legally allowed to discriminate based on non-protected classes as long as the non-protected class is not being used as a proxy for a protected class.
I'm not sure about the problem of brittleness caused by buggy scripts you must rely on -- you'd get that in any language. But if the brittleness is caused by slightly different dependencies being installed for each developer or CI machine, I also recommend creating development environment setup and activation scripts that create a reproducible development environment (based on a requirements.txt generated via pip freeze, committed into the repo; or similar).

Even if the platforms you depend on don't do this, you can do it yourself. It won't fix their bugs, but it will make the development environment more deterministic.

I agree that not all embedded developers should have to work with daily or even monthly. Ideally, all they have to do is run to commands:

./scripts/setup-dev-env
source ./scripts/activate-dev-env

However, embedded software development heavily relies on invoking build systems, compilers, analyzers and other tools -- calling project-specific programs and scripts. At least one person on each project should be familiar with setting these up for the 1st time, document their usage, and support others.

It seems likely that they simply designed it for a max expected water temp and they're exceeding that max. If you need more water to cool the same amount, you're gonna need some bigger pipes.

It occurs to me that the "you're helping" might read as snark and it wasn't really intended that way, or at least, not as snark at you, but rather all of us.

It's silly to reject help from e.g. peer review, static analysis, smarter / safer languages. If you look at some tool and say "What kind of idiot would make the mistakes this catches?" the answer is almost certainly "idiots like you".
Lower than human driven cars? I think it is just basic math at that point when you try to generalize things.
> But actually, it's only been that way for a handful of generations. For about 300 years or so. Prior to the industrial revolution, the pace of technological innovation was so slow most people would not notice it within their lifetime.

It looks that way to us, but that is merely because we are too removed from that world to fully recognize how much things changed. As someone with no personal experience farming, the switch from say ox drawn to horse drawn plows, or from two field to three field systems might seem to be no big deal, but for an agricultural society they were very much revolutions. The printing press with movable type would utterly upend european society in the early modern period. But these are just the big events comparable to say the invention of the solid state transistor - lost to time were all the much more mundane tweaks to technologies that nevertheless would have had great effect on peoples day to day lives. Of course innovations did not spread as quickly due to slower means of communication and the lack of mass production meant it took some time for new items to replace old ones, and a generally lower standard of living made life simpler overall, but accounts from the past clearly show that people of the time still viewed the change as significant and there was substantial intergenerational angst.
I have a daily routine: 3x5 second horizontal handstands, 10 pull-ups and balance on one leg with eyes closed. It takes less than 5 mins, easy to make a habit of and really makes you feel and look better. Sometimes I throw in some stretches too.
According to German sources the government denies this report and points to the currently running evaluations. (e.g. https://www.rtl.de/cms/atomkraftwerke-in-deutschland-verwirr...)
Being inside those old repurposed telecom buildings can be WILD. I was in one that had overhead bundles of ethernet and fiber that had to be multiple feet thick, with the ladder rack bowing down under the weight. Elevator shafts were repurposed for running wires and fiber.

And then the building Google owns in Manhattan: https://en.wikipedia.org/wiki/111_Eighth_Avenue

That had a bunch of carrier hotels in it, I'm not sure if Google managed to kick them all out yet, since many had long term leases. But the building has a bunch of truck elevators in it... literally can load a truck up into the building. And a ton of fiber connectivity's which is why the carrier hotels were in there.
It always makes a lot of sense - time saved is time saved.

Flying east fast after a day of meetings means you get in bed on time.
Correct. Seen this exact scenario and opposites.

In the end - many companies aren’t super rigorous about whether your code that was written passes a test suite and compiled correctly.

I’ve known a few (token) people who have said that they were able to just “talk their way out of having to do leetcode” when presented with the problems. In my personal experience - there’s no way to do that at FAANG and crew if you’re not part of a special group. You either solve all problems asked optimally while not being part of a group the person hates or you don’t pass.

It’s no coincidence that certain races consistently give me leetcode hards as I’m not in their specific group. It’s also no coincidence they still give me a no when I solve the problem optimally when others give me a yes. ;)
Billions of people travel in cars. Those lives are on the line every day. One million people die in car crashes each year. The amount of injuries to people and property is huge. Preventing most of this carnage is a major goal of these self driving car initiatives. How many deaths from someone not following explicit instructions of always being ready to take over from the beta version of some self driving car system would you accept to save 1/2 a million lives per year? One, ten, one hundred, one thousand, more?

Beyond any research that you undertakevaround matrix, i would add: while its not new (having existed for several years now), its popularity has increased quite a bit in the last year or 2. So in my opinion its still early days. Althougj its evolved quite nicely. So some rough edges might be encountered - more so on the client/apps side, less on protocol side - but as the superfan that i am, i really feel it represents the future of distributed messaging, which one use-case is chat. Good luck!
More cooling towers would mean more water needed, since they rely on evaporating water. With river levels already low, I bet they're cautious about using more water.

I wonder if they're considering refrigeration, or if that's even feasible. Conceivably, you could use the power from the nuclear plant to cool itself, since refrigeration has a higher-than-1 coefficient of performance.

As a white person, I'm so sorry to hear about your internalized racism. /s

In all seriousness though, this is an aspect I really detest about anything related to "diversity". It doesn't really seem like it's actually about helping anyone, but more an opportunity for white people to pat themselves on the back without really doing anything other than policing language. All the people I know who "care" about diversity only started caring when it became part of their job.
I've never owned a smart-phone. Since I left the wireless industry I've always had a disposable pre-paid flip-phone that is not in my name. I do not feel isolated. I talk to the neighbors all the time and work with them on my homestead. If I needed more social interaction I would join one of the local churches despite not being religious. That would keep my social circles local. If I need to talk to family I radio them. FRS/CB

If the internet went too far sideways I could have a chat server and forum for local folks as most folks here are on the same fiber/dsl network. I already have some servers that are restricted to the CIDR blocks of my provider.

This might be interesting from a CS perspective, but useless to developers who have to create real life messy business applications.
Sure is (first link has the address). I was there once around '09/'10 for a tour and only remember them showing 2-3 floors which, again from what I remember, was the shared colocation space at the time. IIRC at least one floor was newly built out and barely occupied. We signed with them and I never had to go inside again.

As far as Chicago goes from what I remember someone at the company had a bad experience with DRT so we never looked at 600 S Federal but we did look at Equinix at 350 E Cermak (which REALLY stands out) and a handful of others that weren't memorable.

Thanks for the added detail!
FWIW the calorie counting model has worked well for me where others have failed. Anecdata, of course. But counting calories, as well as making some general, loosely-held shifts of what I eat (near zero liquid calories, minimize sugar, more fruits and veggies, max one fist-sized portion of meat per meal) have gotten my weight down significantly, and it feels easier than other methods I've tried.
Why not use AWS Security Hub? It already supports reading in all your accounts into a centralized report and running it against multiple standards.

You do pay for it (~$30 a month for my job) but you quite literally check a box and have no setup.
Having to debug X or audio breaking several times even over 10 years is a non-starter. Had these issues 0 times over 10 years on mac, albeit on several machines, but I think it’s extremely rare for someone to reinstall Mac OS ever. Only time I did it was when I tried to setup a hackintosh and that really broke some things.
You probably cant test it anymore, but I think it might have had something to do with the keys.

Yeah, so all that effects is CO (calories burned). This does not disprove CICO. I see Fatima has a limited grasp of logic.
Is it really a waste? I work in IT security and I find HN (and some other sites) very useful. Much insightful stuff in the comments.

The Republic XF-84H "Thunderscreech" was an American experimental turboprop aircraft derived from the F-84F Thunderstreak. Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the program's cancellation.

[. . .]

Unlike standard propellers that turn at subsonic speeds, the outer 24–30 inches (61–76 cm) of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards. The shock wave was actually powerful enough to knock a man down; an unfortunate crew chief who was inside a nearby C-47 was severely incapacitated during a 30-minute ground run. Coupled with the already considerable noise from the subsonic aspect of the propeller and the T40's dual turbine sections, the aircraft was notorious for inducing severe nausea and headaches among ground crews. In one report, a Republic engineer suffered a seizure after close range exposure to the shock waves emanating from a powered-up XF-84H.

The XF-84H design top speed was Mach .9 and probably made it to .7 in testing.

Upwork is a gig marketplace, like Fiverr, and they charge for their service. In the world of freelancing sites like Upwork and Fiverr are near the bottom in terms of finding quality work, establishing long-term relationships, and earning a decent income. You have to compete with tens of thousands of people, many of whom will charge as little as $5 to $15 per hour or a couple of hundred dollars for a fixed-fee project. The customers are often cheap and disorganized. It's possible to make a living on Upwork, but the people I have met who do make a living on those sites all live in low cost of living countries like Indonesia and Bangladesh.

Competition is always most fierce at the bottom, and that's what you'll see on Upwork and Fiverr.

The best sources of freelance work are, in decreasing order of effectiveness:

- Referrals from other clients, other freelancers, colleagues

- People you meet through your professional network, at meetups and conferences, and through introductions

- Recruiters, many of whom will place freelancers

- Your own online presence and reputation

- Contacting potential customers directly

- Online ads (Craigslist), gig marketplaces (Upwork, Fiverr)

So what you want is a good network of other freelancers, business owners, people who work with businesses like graphic designers and web marketing people, former co-workers and business colleagues, reputable recruiters, etc. Freelancing is a people and relationship business, not something you can do passively online.

You can look at agencies who represent and place freelancers and consultants. I work through 10X Management. Other agencies with a similar model exist, such as Toptal. Of course they all take a cut for their services but they are doing marketing and billing/payment for you, and writing the contracts, so that has some value.

I have a couple of articles on my web site about freelancing you might find useful.

Yeah, same. Maybe it's all mental, but it doesn't feel like it.

That said, I imagine you also aren't making a habit of it. Maybe training every day and then accidentally taking a week off give you some recuperation you didn't realize you needed.

Also, I’m not sure how you’re missing the very acrimonious Colorado River negotiations b/t upper and lower basin states. Upper basin is refusing to commit to water use quotes in 2023, lower basin states aren’t addressing the root cause at all while asking for cuts (my bias - this how the upper basin probably should act without rational acknowledgement and concessions of why Co/WY/UT should sacrifice water for Almond farms in CA and Arizona suburban sprawl and golf courses in literal deserts).

If you’re not aware of how heated this is getting, you should check in. It’s about to shape a tremendous amount of water policy for us, however it turns out.
