IPA/IdM is the gold standard for user management on a fleet of servers.

Gluster is the best replicated filesystem hands down and Ceph is the only alternative to expensive SANs that scales well.

Ansible is by far the most popular config management tool.

Foreman+Candlepin/Satellite is one of the few sane ways to do patch management.

There are a lot more things RH has under their belt that I could talk about but I just did the list that was mentioned.
All countries already have infrastructure for strategic gas reserves that are sufficiently sized to cover demand for long periods. So storing renewable energy via power-to-gas processes is probably the way to go.
My understanding is the passcode and timeout behavior is on dedicated hardware that's tied to the OS level encryption. It's not possible (or maybe just not feasible) to replace or update this hardware.
Escape rooms are NOT big business because a) no repeat business and more importantly b) they scale terribly.

If we're entering conspiracy theory territory, why couldn't Epstein use said resources and connections to find a lookalike/prop artist, buy people and fake his own suicide?
Thanks for your comment. I'll download this and try it out. I like the idea that your app is opinionated. It shortens the amount of time of setup.
> if does not have a return value in a language like Java. In other words, it is not an expression, but a statement. Because everything in Clojure is an expression, there is no equivalent construct to Java’s if in it.

Anyone know the language design rationale behind the way Java does it? It seems much easier to make everything an expression. Ive always disliked that part of Javascript and being forced to use ternary operators to do a single line return statement for a conditional. Same with case statements.
That depends on what you mean. My knee jerk reaction is, no, I don't. But they're different cars for different purposes for me (as an enthusiast). I sold the R around the time we bought the Tesla because the only thing we needed less than 1 $40k car is 2 $40k cars. (We've got 4 cars at the moment, though I'm currently at CarMax trying to get rid of one of them).

The Model 3 is the first appliance car I've owned. But I went into this eyes wide open; it was the right decision at the time and it's still the right decision. The R I basically stopped driving when I got a new job where I biked to work for a year. The Model 3 was a replacement for my wife's 175k mile Subaru, and we bought it immediately after my company was acquired and we started carpooling together. The 3 is a better commuter/appliance more suited to 2 drivers who trade off, cheaper to run, gives us HOV lane access on the rare occasion where one of us drives solo, and my wife hadn't driven stick since she lived in Australia many years ago so she didn't really show interest in driving the R.

The R was my (other) fun car, with all the euro goodies on it. It was fantastic everyday runabout, fun car, roadtrip machine that could eat miles like nobody's business. The 3 is, again, an appliance. I don't really like sedans, but I wanted an EV, and I like Teslas, but could never justify spending the coin for an S.

Given infinite money and space, I'd still have the R, too. Though I'd probably never drive it, because it's so easy and convenient to just hop in the Tesla and go, any time, anywhere. It never has to warm up, it never needs me to stop at the gas station before I run my errands, hell, I don't even need a key.
It’ll probably get stolen or vandalized in that area. Source, I live nearby.
Many of these got added to OpenStreetMap at that time. OSMAnd will announce them, the last time (years ago) I used it while driving over some the implementation left a bit to be desired, it announced them about 10 times.

Here's a quick query visualizing just how many there are:

I think the FRA data includes information about what type of control each crossing has. It wouldn't be a huge project to highlight the less controlled crossings that are on higher speed and higher traffic routes.

> But you have to understand that there are a lot of highly educated, highly paid people trying to figure how to make their products as addictive as possible to as many people as possible. So a lot of people stand no chance because their weaknesses are being exploited with precision

This is the leap I don't buy. First of all, it's factually incorrect: you're not being targeted with anything like precision. I worked in AI research before the boom and work between research and product now, I'm likely better than most of the highly educated, highly paid people you're talking about, and ML models aren't the otherworldly wizardry that people think they are. They work well on average; there's no highly paid team dedicated to analyzing wutbrodo or ididntdothis's usage and building a custom model. If you're making a mild effort to recognize and push back against mindless media consumption, you've already moved yourself away from the center of mass being targeted. And frankly, these companies aren't going to chase after you when the bulk of their usage comes from the chunks of the population whose behavior clusters better.

> Do you have no habits that annoy you but keep coming back no matter how much you try too get rid of them?

Honestly? No, I don't. I don't think I'm even particularly good at moment-to-moment willpower either. I just look at it differently. To take my diet as an example, it's almost exactly where I want it to be from a health perspective. It's to the point that my friends assume I'm some sort of iron-willed ascetic continually putting in effort to eat well, but it's completely effortless for me. But it took a literal decade for me to get here, through incremental change and letting my habits (and probably biology) adjust. If I had been in a rush and gotten repeatedly frustrated at my lack of rapid progress, I doubt I would have ever ended up here.

Reducing mindless media consumption and usage is similar (though in my experience, takes far less time), and is helped along by any number of apps and extensions.

This isn't a general argument that this is trivial for everyone, nor that regulation is inappropriate to help the average person who hasn't recognized the problem. What I'm pushing back against is the claim that "there's no hope of escape" for most, barring some extreme level of informedness or willpower. There are highly paid people with decades more experience making junk food hyperpalatable too. But while there's scope for regulation to help the average person, it'd be both inaccurate and unhelpful to claim that "there's no hope of escape" for an individual from the Standard American Diet.
An alternative grip exercise that can be done anywhere and avoids the injury risk of climbing, is to alternately make a fist and then open your hands as far as possible while spreading your fingers apart. Start slowly and gradually increase the speed and repetitions. Be sure to have at least one rest day between sessions (I actually think two rest days is better). After a couple of weeks, you should be able to do it extremely quickly for hundreds of reps until your forearms are completely fatigued. In each workout, try to open and close your hand more quickly than the previous workout. Make your fingers look like a blur of motion. It is surprising how completely fatiguing this can be after just a few minutes.

These principles are presented in the context of a game, their goal is to make the gameplay more fun. Applying these to real life seems a long shot.

I don't understand your parenthetical assertion that domestic abuse and mass shootings are not crime. Of course, they certainly are crime.
That just means it will take longer for the full effects to kick in. The gun lobby puts out tons of arguments that amount to "your proposed solution isn't perfect so it shouldn't be done."
And that's also a good defensive move.

Given the market is moving, even IBM's major customers would eventually migrate to newer technologies. (On the order of decades)

By providing something that mostly satisfies that need, IBM essentially drilled a relief well to take the pressure off. When they're ready to migrate, they could get 80% value of what a non-IBM migration would get them by moving to IBM's product.

For a lot of large, slow, conservative orgs, that's good enough.

She contacted the legal team and they went back and forth and finally decided that no, we couldn't have our fee waived

You’re really telling me that their legal team told them it would be a breach of their contract for Verizon to issue a refund? What could the lawyers possibly be worried about would happen if they charged their customer less?

Verizon and Comcast are two companies I avoid at all costs.
There is no reason to discontinue their mainframe business. Banks and other institutions have applications running successfully on those platforms. The industry has learned that it is better to integrate applications than to replace—especially when the replacement is a 40 year old app that runs the business.

Let's hope we didn't just replace 40% of electricity with renewables by 2040, or we can probably kiss civilization as we know it goodbye. We need to reduce global carbon emissions by 50% by 2030 if we want a fighting chance of staying below 2°. That's much more than just electricity.
Works great for kg/lb conversions too.

kg x2 + 10% = lbs

lbs /2 - 10% = kg

I've yet to find a fast one for C to F temp conversions though. It takes a bit longer to do the 9/5-5/9 + or - equation in your head.

"p" makes sense if you know that it stands for "predicate". It's not nearly as arcane as car and cdr.

Also can we finally settle on a name for these things now? If car and cdr are too arcane we can do away with them (though I like being able to do caddadadr) but why do we need "first" and "rest" rather than the already established "head" and "tail"?
I particularly dislike "rest" since it's a relative term, i.e. in normal speech saying that you're going to do something with "the rest" of the list means something different depending on how much of the list you already used.

Did the person sizing the solar panels in this hypothetical forget that it was sometimes cloudy? Seems a rather silly mistake.

Wouldn't they have access to data predicting to within fairly narrow margins how often this would occur statistically?

I mean if cloudy weather reduces the output by a factor of 4 then you don't really need to bring long term storage into the matter to have trouble if you're going size everything on the basis that will only provide the required energy on the very sunniest days.

For comparison, here [1] is a wiki article on a different recent radioactive release from Russia (of Ruthenium-106). International parties detected it very quickly, but it took a fair time to trace it back to it's probable source at the Mayak facility. This current event seems in some ways more serious, in other ways less, but a bit better in terms of the transparency in the Russian governmental response (they've at least acknowledged it).

Tavis Rudd's Using Python to Code by Voice [0] is also interesting.

Looking up that URL, I came across the more recent Coding by Voice with Dragonfly [1]. Haven't seen that one yet, but just quickly skimmed through. Unfortunately the live demos are silent (you can't hear speaker Boudewijn Aasman talk to the computer), but it seems worth checking out if you're interested in setting up some recent voice recognition software with your own custom voice command syntax.

Perhaps it’s simpler and more efficient speed control circuitry. For a DC motor you just need to step down the DC voltage from the batteries. For a brushless motor you basically need a variable frequency inverter that’s necessarily going to be more complex and possibly less efficient.
Are any JavaScript developers excited for Blazor?
I see a bunch of hype about Blazor and have dug pretty deep into the framework and certainly see some exciting developments.

However, I haven't read much about the opinions of really talented front end engineers who currently love and prefer javascript / typescript. What do you think?
Why do you think that this is a meaningless metric. It seems to me that we need at least enough storage to last for a night. Realistically we need enough storage to cover reduced production and increased demand through winter.

The paper proposes that the entirety of dark matter is a massive free (as in non-interacting and non-self-interacting) field that appeared at the end of inflation, but before big bang nucleosynthesis ("BBN"). In order to make this work with observations of the cosmic microwave background, the field has to have much lower mass earlier during inflation than at inflation's end. The mass-gaining mechanism is not elucidated.

There is only one known scalar field -- the Higgs -- and it is far from a free field.

Any non-gravitational interaction between this proposed field and the rest of the universe (including self-interactions) after the end of inflation is incompatible with this proposal. (One contrast this with other proposals such as WIMPs, which are not free fields, and typically also not scalars) and axions (which are scalars, but are not free); most of these are explicitly non-free because they also try to solve some problems in the Standard Model of Particle Physics via new interactions).

The phase between the end of inflation and before some of the dense matter (mostly the quark-gluon plasma, and ancestors thereof) condensed into nucleons and nuclei is far from the much hotter and much much denser phase in which quantum uncertainties and classical curvature do not obviously play well with one another. Barring very early black holes from direct collapse (perhaps seeded by overdensities in this massive proposed field), touched on in this paper only very briefly as "enhanced structure formation", the post-inflation/pre-BBN universe this paper describes is free from strong curvature requiring any sort of quantum gravity: one is safely in the land of quantum field theory on (classical) curved spacetime, and in practically any small spacetime region after the decay into the proposed massive free scalar, one can even ignore the (global) curvature.

The paper proposes constraints on the mass of the field and on its ancestor field(s) but otherwise does not contemplate the much earlier universe. The central feature of the paper is that it commits totally to minimal-coupling (i.e., the late time field is truly free, other than gravitation). The field contents generate and respond to curvature, and that's it.

The paper also features what appears to be one of the most confusing initial two sentences that science writers have latched onto in many many papers...

Finally, I think it is better to link the abs page than the PDF directly. Speaking only for myself, the abs page has puts significant and useful metadata front-and-centre and other metadata at the same reliable one-click distance from the PDF itself. Not all PDFs make it easy to go to the abs page in a click, and fewer still suggest that the PDF itself may have been superseded by a subsequent revision (or by publication somewhere in final form).

For this paper, the abs link is https://arxiv.org/abs/1905.01214
In Clojure, first and rest apply to sequences, which are a logical list abstraction. They apply to lists, but they can also be used on sequential views of indexed vectors, maps, sets, database result sets, files in a dir, lines in a file, and an open world of "things that can be seen in some order". head and tail I suspect are much more tied to linked lists and data structure than the more plain first and rest.
Meanwhile, there is something special about base-12, namely that the log base 2 of 3 has a really good rational approximation as 17/12, the log base 2 of 5 has a pretty good approximation as 7/3 (you can do better with 28ths).

This is the basis for the 12-tone equal temperament scale in music, and it only works if you use base-12. So if we used base-12 for our numbers then someone would have the bright idea to name all of our musical notes with numbers and we could just do a key change (or chord formation) by addition.
Perhaps it would be nice if I got a small verbal audio cue from whatever navigation app I was using a minute or so before reaching the rail crossing. We already get these notifications when it's time to make a turn and rail crossings aren't so frequent as to make such warnings annoying.

Neither do they need three-point-anything accelerations in the environment you describe. The only thing that makes it not a bad thing is that they don't have to trade much (if any) efficiency at more modest loads to achieve this, very much unlike their ICE brethren who want similar numbers.
IBM products have no license-checking built in, on purpose. They want you to make more copies than your negotiated license agreement allows. Then, when the auditor comes in, they charge you the sky-high list price, backdating it as well.

If your control structures are expressions then they can lead to code that the maintainers of the language might not want to promote. Remember that language design is not just about being as flexible as possible. If it were we would have stopped with Lisp. Languages are also designed with readability, portability, and simplicity in mind.

Imagine if you could write this (nonsense) code in Java:

bool a = (while (b) { if (c) { b=d;} else { b=e; }});

While it is efficient, some may balk at how “implicit” it is.

I miss the old IBM Thinkpads; sure, they cost $4,000 during the height of the dot-com boom, but those things were built like tanks. I got a 600X when a dot-com was liquidating its assets for $700 and it was my primary computer for over six years.

The newer Thinkpads from Lenovo are more like wannabe Macbooks; I miss batteries you could swap out without opening the computer and Thinkpads you could open without using a spudger.
