Undefined behavior and null terminated strings with the attendant buffer overflows are not fundamental constants of low level programming; they’re implementation details of C. Rusty (and Nim, Modula, Pascal, Ada, etc.) show that it’s perfectly possible to write low-level code with zero-cost abstractions without “unsafe by default” programming languages like C.
Under the hood Stan attempts to find globally optimal parameter values for your function which you've expressed as a joint probability density. To do this it relies on the same MCMC theoretical results which indicate how the recursive process of sampling and posterior updating leads to the global optimum. The big deal about Stan is that its algorithm for doing this is state-of-the-art, and that it can work with a huge variety (including custom) density functions by utilising auto-differentiation.

Sampling is a slow approach when there are other alternatives. For example, if you are after OLS regression, you can do the equivalent with Stan but it may be an order of magnitude slower than plain OLS. Further, the calculation of your likelihood function will scale linearly with the size of the data. But adding new parameters will scale exponentially, so you may find that a model with 2 free parameters which takes 10 minutes to fit takes 2 hours with 3 parameters.

A good thing about Stan however, is that it is parallelisable so you can run it on many cores (and it will scale linearly for a good while) and you can also run it on MPI across many machines. Some regression functions with very large matrices support GPUs (although Stan requires double precision to work). So to some extent you can "throw more money at it" to get a result out and it has been used for very big data problems in astronomy for example which however utilised something like 600k cores if memory serves correctly.
tl;dr - if we don't create it, control it, and make sure everyone knows about it, someone else is going to make all those decisions for you. Its coming regardless

These are not equivalent comparisons to me. Tobacco was always harmful, inhaling smoke in general is just bad, and the others could be through improper use but safe otherwise. Let alone all of what you mentioned will not have the impact AI will

AI's potential is equally good and equally bad and any of the bad is purely because someone or some group employs it that way.

The real danger of AI isn't the obvious tinpot dictators using it drive war but in politicians and government officials hiding behind the term as an excuse for their bad decisions. The more you demand of your government to give you stuff or services the more likely you will be subject to this tech

I say this each time the subject of AI abuse, facial recognition or similar comes up.

This is not something that cancel culture will stop. Nothing is going to stop it from coming. So the best alternative to the technically and morally (hate using that word) driven people is to hit it head on from all directions. This means working to make sure it does what it is supposed to do but also that everyone knows what it really cannot do, working the legal end to insure there are laws and consequences for employing the technology incorrectly, and through the information end in keeping the public fully aware of who is using, how they use it, and how to legally protect yourself from it.
"Defunctionalising" makes sense for performance. Ability to debug is a pro. I wanted to point out the similarity between these separate methods. In any case though, I would hope that an optimising compiler would not push onto the stack variables which are not used later in the function. Repeatedly pushing a pointer to the structure you're working on is indeed an overhead of recursive calls.
Mit to mention that the fact that European states are so authoritarian and immoral about it incentivized theft and deception. I wouldn’t have even bothered reporting anything if I were him, and this case seems to prove the point why. They’ve likely also note through their draconian policies lost the information on where the finds were made and all associated historical knowledge, e.g., the coins of a certain type would indicate the location of possible troop movement that was not clear before.

Maybe someone could share their experience who has made the switch recently. If it is not a big thing that could potentially break everything, then I'd be happy to try it out.
It's too bad YouTube doesn't let you keep your history (so you can go back and find something you saw before) without it feeding into recommendations.

For me YouTube recommendations are not toxic, they are so amazing I some times wonder how comes the world around is not heaven when everybody has free access to this.

That's because I always watch high-quality educational content and some beautiful comforting and inspiring music. So for me YouTube is a fountain of knowledge, visual and musical aesthetics etc. Every day I get inspiration, healthy kind of fun and learn something cool, useful and healthy.

But people who watch stupid and destructive stuff (even once) are doomed because they are going to get the same and worse kind of content recommended over and over. This is a particularly underestimated social problem indeed.

That's why I recommend to avoid signing-in into YouTube. Better watch anonymously so you can always clean the cookies and get out of the pit.

It's the equivalent of the Valley Forge Rocket. An arduous trial in the birth of a young nation which incidentally happened to go on and genocide an entire continent of indigenous cultures and people's and forever remove them from the world's collective heritage.

No, it's not the 3.98-4.0 GHz gap.

> Given the neighboring aviation band (from 4.2 to 4.4 GHz) allocated exclusively for vital aeronautical radionavigation equipment

They are afraid of (a) heavy use in the 3.7 - 3.98 GHz band (fundamental emissions) and (b) "accidental" broadcasts in 4.2 to 4.4 GHz range (spurious emissions). The study [1] on p. 12 in §6.1.1 basically assumes the 5G equipment will blast an interfering signal on altimeter band at full power. I think any frequency allocation request can be shut down this way.

And I don't think 5G network will work properly if even a fraction of the assumptions in that report are true. If you look at https://en.wikipedia.org/wiki/5G_NR_frequency_bands, you will see that bandwidths are in 10s of MHz and the sub-carrier spacing [2] is as low as 15kHz. If 5G radios will be off by 15kHz (as opposed to 202000 kHz from 3.98 to 4.2 GHz as the aviation industry is implying), 5G network transmissions will not work properly.

Is this just another piece of data confirming that it is a bad idea to place market orders? With a market order you are essentially saying to the broker "I want this stock right now, you can decide what the price is". With a limit order, it seems much harder to pull any tricks.

It seems like market orders are, and always have been, for chumps. Robinhood is just being more shameless about abusing them than previous brokers.
But they don’t emphasize it or mention it officially during orientation. It was only mentioned during one of the smaller tech trainings facilitated by a longtime Googler. To paraphrase their words, “I’m not sure why we don’t say this anymore.”

So the statement that it’s really not a slogan anymore is quite true from my experience.

Bayesian modeling has a somewhat distinct feeling to both (typical) deep learning algorithms and boosting/bagging classifiers.

Most particularly, Bayesian modeling tends to be generative modeling as opposed to discriminative. This means that you construct your model by describing a process which generates your observed data from a set of latent/unknown quantities.

For instance, we might observe that n[u, d] clicks are observed on user u on day d for various choices of u and d. We could build a variety of generative stories here: that n[u, d] is independent of u and d, just being a random draw from a Normal(mu, sigma) distribution; that n[u, d] incorporates another unknown parameter p[u], the user's propensity to click, and then is a random draw from Normal(mu + b p[u], sigma); or that we also include season trends sm[d] and ss[d] to both the mean and spread of n[u, d], saying it's Normal(mu + b p[u] + sm[d], sigma * ss[d]).

In these examples, the unknown latents are parameters like mu, sigma, and b as well as any latent data needed to give shape to p[-], sm[-], and ss[-]. Once we've posited the structure of this generative model, we'd like to infer what values those latents might take as informed by the data.

This is the bread and butter of Stan modeling. It lets you describe these generative models as a "forward" process where we sample latents in a simple forward program. Similar to Tensorflow/etc Stan extracts from this forward program a DAG and computes derivatives, but instead of simply maximizing an objective function through backdrop, Stan uses these derivatives to perform a sampling algorithm over the latents (mu, sigma, b).

Ultimately, this gives you a distribution of plausible latent configurations given the data you've observed. This distribution is a key point of Bayesian modeling and can provide a lot of information beyond what the objective-maximizing value would. As a simple example, it's trivial from a Bayesian output distribution to make statements like "we're 95% confident that mu > 0.1".

The pronunciation of something is secondary to its definition. But with a phonetic language, it's easy to fool yourself as well as others of an understanding that is not very deep.

well, children are introduced to "reading" as in mapping written symbols to phonemes. Yes, there's more to reading than that, as in you can side-step the mapping to phonemes and map straight to "meaning", but nobody is doing that with children. Phonetic languages just make the (indispensable) step of text to sound easier and gives you a head start.

The SEC decision seems a little harsh on Robinhood. If RH had executed all of its customers orders on the public exchanges, instead of routing any to brokers, it would be in the clear (and a lot of people would be saying how great it was that RH didn't take payment for order flow). Directed orders are absolutely fine.

But because they chose to shop around for better prices than they could have achieved with directed orders, they had an obligation to pass on more of that price improvement to the customer. How much more? It's not clear. Seems like the SEC is hinting at "roughly as much as everyone else does" - brokers shouldn't be allowed a business model that subsidises low trading fees with high PFOF.

Other brokers subsidise their low or zero trading fees by collecting interest on their customers' cash balances. This only works when the balances are relatively large. The SEC's approach arguably encourages transparency, but I don't find either business model particularly transparent - the bigger effect is to discourage brokers targeting smaller clients.

I've recently tried 10 or so schematic capture programs from Ubuntu repository and my experience was very bad. Designing single transistor amplifier was almost impossible in most of them. Ridiculous ui, crashes, simple things like changing resistor value and seeing change required 10s of clicks. I ended up designing scheme in caneda, then I made a screenshot and exported netlist. Then I made simple app in lazarus where I put image in the window and added panels atop of each element, when I scrolled mouse above panel it changed that value in netlist by 1% and instantly run netlist in spice and rendered transient chart. No clicking, no switching modes, no dialogs. In hour or so I had amplifier tuned. Doing this in any of those existing programs would take me a month.
That's okay, I've noticed google has started to make it completely useless in any case. I tried to watch a speed run for a game (~2 hours) recently and google deemed to interrupt me with an ad every 3-5 minutes. Not even TV does that.

There used to be a hypothesis that DNA originated in viruses and that the three branches of life (archea, bacteria and eukaryota) evolved when three different DNA viruses encountered preexisting RNA-based cells. (https://www.pnas.org/content/103/10/3669)

Nowadays however it is more widely believed that eukaryota descend from archea, but anyway it's pretty much a given that viruses are not and have never been alive. And while the opposite has happened, gene transfer usually goes from viruses to cells, endowing them with new abilities, more than the opposite direction.
The "ungolfed" code looks like this:

<input id=i>
<a onclick='u.innerHTML+="<li onclick=innerHTML=innerHTML.strike()>"+i.value'>+
<a onclick=u.innerHTML="">X</a>
<ol id=u>

There are 4 occurrences of "innerHTML" and 3 occurrences of " onclick='" so I replaced those two substrings with H and o.

The whole HTML is rendered using an ES6 template literal (document.write(` ... `))

Everytime a ${H} or a ${o} is present in the template, the value of H or o is copied here.

It's a native feature of JS since ES6.

Besides that, the second <a> implicitly closes the first <a>, so no need to use </a>. The id's are global, that's why we can access i.value or u.innerHTML directly. In onclick, "this" (the current element) is implicit. Finally, the strikethrough is done using the (deprecated but still working) .strike() String method.
yes, yes, I said that already: "...multiple independently-owned verification nodes..."
The trick was to know beforehand what would work and what wouldn't. That way you only had to spend a couple of hours in the end fixing small things that were broken in IE. A couple of well-placed "zoom: 1" could fix a lot.
HTML absolutely used to “say how things needed to be rendered”: with tags like B, I, FONT and so on. It was developed when documents were expected to be WYSIWYG-style markup (Word/WordPerfect, Latex, etc).

CSS was designed to strip that away only after people decided the future of hypertext should look more like XML. In doing so, they added the constraint that you should be able to get completely different outputs depending on which media you use to access the content - which at the time largely meant printing vs browsing.

But I agree that the whole thing was fundamentally document-based and has been bent out of shape in the subsequent decades. Once the content/presentation separation was abandoned, all bets were off. Now we are in a situation where content is driven by CSS properties via JS manipulation. We have the worst of both worlds. Ironically, this was enabled by something called XMLHttpRequest...

Is there an error in this sentence or am I misunderstanding something: "But in other languages or environments, the stack space may have a hard limit, and it may be advised to not use unbounded stack space." - I'd say it might be advised to use unbounded stack space, and the current text uses double negation.
I agree with placing limit orders instead of market orders, but if an illiquid stock is quoted at 20.00 to 20.10, placing a limit order to buy at 20.10 is not much different from a market order, at least for a small number of shares. It's possible some brokers will offer more price improvement than others in this trade, filling you at less than 20.10.
What Toyota and VW have is politics and that's why they are still trailing behind Tesla. Big parts of their engineers and managers have expertise and background in internal combustion engines and this means much more coupling with this technology. A turnaround in such businesses is much harder than in software, so I expect that only those of the traditional manufacturers who can rebuild their strategies and sell it to their middle management to survive the next decade or two.

DHH Announces Release of 'New Magic' for Ruby on Rails

I believe you are correct, but the real issue was not the firearms the robbers were using, but rather the penetrating power of the police firearms against the robbers' body armor[1]. Because they were both wearing body armor, the two bank robbers were shot a total of 40 times without being killed. (One shot himself and the other bled to death).

Police at that point were mostly using 9mm pistols, .38 caliber revolvers, and 12 gauge shotguns, none of which were capable of penetrating the body armor. More heavily armed police such as SWAT were using MP5s, which shot 9mm as well.

The robbery lead to the distribution of higher velocity firearms like the M16 among the LAPD, and a similar incident in Miami lead to the adoption of the 10mm pistol cartridge by thy FBI.
