Yes, there are complex dataflow (ah!) dependencies between heterogeneous threads, often bidirectional. Using shared pointers would means trading potential deadlocks with potential leaks due to circular dependencies (I'm not saying it is worse, but it is a tradeoff).

> How is instead dedicating a single core a worse solution?

It is pretty much guaranteed to perform worse, if that's what you mean. Is it worth the effort and extra complexity? Probably not.

The timestamping jitter with an FPGA would probably be on the order of tens of nanoseconds while we're talking microseconds with a software solution.

> There are no gains from custom hardware as network variability would mask them.

I _think_ multiple cascaded jitters in a system add with the square root of the sum of squares, so there would still be an improvement.

Consider a system where you had 10 microseconds of inherent jitter, then you added another 10 microseconds on top of that. The total is not 10 microseconds - it would be 14.
Of course it's influenced by expectation. That wine students get it wrong when misled is hardly surprising. The question is, what does it actually mean?

Wine experts regularly identify wines when blinded but not misled. The "subtle flavors" are objectively there -- you can see them on a gas chromatograph. But the experts aren't there to be poor-quality GCs. They're there to identify wines that other people will think are interesting.

Some people find the language they use to describe it off-putting, but they're just trying to describe a sensory experience, using familiar language in unfamiliar ways. It's readily understood by their colleagues.

There's an objective difference between that and "power of suggestion" that's poorly conveyed by this article. I believe that's why the article is dated and lacks follow-ups. It doesn't say what people think it does, and researchers either didn't bother to look in more details or didn't think that what they found was as interesting.

I'll reiterate that these subtle differences don't have to be important to you to enjoy wine. People get attached to the high prices and snobbery of very high end wines. But that's not really what wine tasting is about, and it's absolutely not necessary to enjoy wine.
Let's say language is a tool to convey information regardless of truth or precision.

You can disguise negative information giving it the appearance of a usual positive one (the fake discount).

It's more a property of information than of language, or rather a property of our information processor, so lazy it doesn't check every single piece 3 times but instead rely on habit and context
That's one particular implementation for one language runtime one common OS. It's neither a requirement of the C language nor of the ELF executable file format.
Not an expert here but have some experience with it:

Assuming that each peer is connected to every other peer via a mesh network [see this image for reference: https://github.com/feross/simple-peer/blob/master/img/full-m...], each outgoing stream (esp. audio / video) is likely going to be duplicated, per recipient.

Scalability over a mesh network is fully dependent on CPU and network performance of all of the connected devices, and I'd doubt it could handle 12 participants if there is video involved, unless all participants are running relatively high-end and modern devices, with optimal network conditions.

You'll need a SFU or an MFU running on the server to handle larger rooms, while enabling all connected devices to only have to send one output stream per media type, regardless of how many connected participants there are.

“What exactly is spacetime? Is it a real thing like an atom, or just a mathematical construct that is used to describe how mass 'generates' gravity?”

This is a false dichotomy. Atoms too are "just" a mathematical construct used to describe how certain observable, physical systems behave. It's even called the atomic _theory_, and like all other good theories it knows its limits. At low enough energies, it's too fine and at high enough energies it's too coarse a model. Spacetime is exactly as real as any other current model of observable physical phenomena that physics can offer.

My "archive file format" of choice today is an assembler. Stuff data into arrays of bytes, then resolve the pointers when you build the "archive".

You then can walk through the structure with pointers like you would in C. If you want to build a directory to give things names, go ahead. I deliberated long before deciding to store the length of the block before the block, but since most of the data structures were variable-sized I would have invented some way to code the length.

It’s great, but highly dependent upon which SRE team you’re on. Google’s internal infrastructure has advanced immensely over the past 5-10 years, which has shifted many capabilities from SRE to dev teams. Over time it has become relatively easy to build the long tail of scalable, reliable services, which has changed the responsibilities of SRE. For some of the larger teams/products, SRE is fundamentally unchanged and is really rewarding, but for others its responsibility has unintentionally evolved to more of a 24x7 operator role.

Well yes, case in point, social media has a tribalizing effect on people. I don't disagree that comments on the internet tend to be polarizing. I wouldn't have commented at all if it wasn't to disagree with somebody, that's normal in these parts.

I wonder what happens when most of the population is relying on such a medium for their understanding of the world beyond what they can see and touch? I don't think me setting a good example here on HN is going to have much effect against the basic human impulses that social media selects for.
Could we introduce this kind of addiction in healthy things, like excising or healthy diet or anything like that?

I read this series some time ago, and I thought there were many gems in it that tracked my experiences that I could not articulate.

For instance, there's a bit in here about rationalism, and how the rationalist community might be good at being "correct", the kind of rationalism espoused, which prizes removing biases, doesn't always result in achieving the desired ends or winning.

https://commoncog.com/blog/chinese-businessmen-superstition-...

To me, a pure rationalism relies on your mental models of the world being correct in essential ways (to use a PCA analogy, in the principal components). However, the business world is one where higher-order effects dominate, so even if you have a rational first-order mental model of the world, that mental model is often insufficient.

This is where the empirical approach shines. The terms are used loosely in the article, but it differentiates between "epistemic rationality" (how do you know that your beliefs are true?) and "instrumental rationality" (how do you make better decisions to achieve your goals?), and the observation is that businessmen with high acumen -- in any culture, I would argue, but especially among the early Chinese settlers in Southeast Asia who generally lacked much formal education -- tended to employ "instrumental rationality" a lot. It was a kind of experimental culture within a conservative culture, which I find fascinating.

This seems to track with how startups work today -- create an MVP, ship, get feedback and iterate -- as opposed to the old product development approach of doing market surveys/focus groups, waterfalling the product engineering and then shipping a shiny product (that potentially no one wants).

I personally think that for most things, first-order mental models (i.e. simple cause and effect) will get you 80% of the way there, but in order to get over the lump of the last 20% of diminishing returns (where higher-order effects dominate), empiricism/instrumental rationality is necessary.

In the flip side, one of the downsides of being hyperrational is to overthink things. All mental models of the world are incomplete, so one can end up optimizing a narrow model of reality. We've all come across stuff that "shouldn't technically work" but do in real life. In many cases, it's more useful to just interact with reality directly. Uber and AirBnb shouldn't work -- some might argue they don't -- after all, who would trust strangers enough to book a car or a room on the Internet? Yet, empirically they do work for the most part, or at least the trust part does.
How many rows? What is the "fast" you expect?

My main app sync data across ERPs and their main case is batch loading of data. This mean that I need to nearly mirror a SQL Server/Oracle/Cobol/Firebase/Etc database into sqlite, clean it, then upload to postgresql.

I have more troubles fast loading into PG than sqlite (not saying I don't have them in the past!) and sqlite is very very fast to me.
It's possible that the newspaper didn't understand what a web search entails.

Yes, if you search for the name of the blog you can find his personal name, but the issue is that if you searched for the personal name you wouldn't find the blog. A search of term to result is not symmetric if reversed.

The wish was that by publishing the name it connected the name to the blog, even though previously the blog was connected to the name. Thats not the same thing and it requires a bit of effort to understand.

For example, if you use the name of one of my online identities it could probably bring up a wiki page saying that I went to the web 2.0 conference a decade ago, but if you searched for the web 2.0 conference you would never find that identity in the search results.

> To do PTP "right" requires every switch to support it and a NIC with hardware timestamps.

I agree, but PTP will in fact work over regular commercial switches on a LAN. The problem is that it will introduce jitter if there's other traffic on the network, but as long as the paths from master to slave (terms used in the standard) remain symmetric, you can filter this out and achieve performance almost as good as if you were using PTP transparent switches.
I simply added a local storage inspector bookmark to my chrome profile, so it gets sync to all devices. Now on any page, I just need to type its name, it will appear in dropdown, & clicking it exports all local storage used by current page or domain as json file.

Code of bookmarklet:

javascript:(function() { var backup = {}; for (i = 0; i < localStorage.length; i++) { var key = localStorage.key(i); var value = localStorage.getItem(key); backup[key] = escape(encodeURIComponent(value)); } var json = JSON.stringify(backup); var base = btoa(json); var href = 'data:text/javascript;charset=utf-8;base64,' + base; var link = document.createElement('a'); link.setAttribute('download', 'backup.json'); link.setAttribute('href', href); document.querySelector('body').appendChild(link); link.click(); link.remove();})()

I hesitated to reply because this is such a subjective issue. I look at the software on the Android and Windows side and just don't see much of interest to me. That's just me though.

I think one area that Apple clearly does excel at though is software features that take advantage of specific hardware features. The fact they design the whole product in sync on both the hardware and software side, without either taking priority by itself is truly unique in the industry. So for example the way the M1 has instructions that accelerate particular operations common on the OSX/iOS software stack, or the computational photography software that works hand in glove with the neural engine hardware.

The fact that apple develops their own developer tools, OS, application software, hardware and even CPUs now is unique in the industry and deep software skills are a really important differentiator. Maybe that side is slipping, but if so that will be a big problem for them down the line.
Well this has all the hallmarks of being very cool.
>A 1660 Ti 4gb RAM laptop gpu, runs about as fast as Collab CPU does

According to the chart on that page you linked to the Lenovo Legion (with the 1660ti) is about 30% faster than the Colab GPU. The Lenovo 480s (CPU only, no GPU) is about the same speed as the Colab CPU. So if you can train your model on the on 4GB of VRAM, a laptop with a discrete GPU (if you exclude the really basic business laptop GPUs) may be useful.

You claim this "thread" leads to all reason and truth being invalid, which is overreaching, to put it plainly. How do you reckon that all mathematics, the periodic table of elements, the planetary bodies in our solar system, are suddenly invalidated because humans weren't deciding to study them, but were merely following natural behavioral patterns? If we don't have free will, does that invalidate all aliens' civilizations study of universal laws too?

In my view, humans are curious creatures whose natural inclination to study their surroundings led them to discover scientific truths, which exist on a higher plane than our mere thought. Combine this with societal support of scientific activity, and we have a burst of discovery of truth and reason which was hitherto un-revealed to us. Our "free will" and "decision" has nothing to do with 2+2=4 or that Mars is red due to rusty iron, these are simply factual scientific observations which have stood the test of time in science: no theories have invalidated them.

So, our free will is not necessary for the physical laws of the universe to exist. They existed before us and will exist after us. So where do we lose all reason and truth by being merely curious, as opposed to having a homunculous man in our heads telling us what to do at each moment?

Look into meditation practice if you still believe in the switchboard operator pulling all the strings in your mind. I challenge you to find free will in yourself, find something you're actually genuinely choosing. Can you explain why free will allows the random thoughts that crop up in your mind constantly? Those random thoughts dictate our behaviors, the actions of humans; but where are they from? They're random nervous firings that our physical body, physical tongue, physical fingers, are all acting upon, there is no "switchboard operator" choosing anything at any time.
It's got a very helpful transaction block wrapper structure that allows you to do some really interesting things with database transactions.

To be perfectly honest, one of the things that I always love about Rails is exactly how good the database layer is with ActiveRecord. I like using the advanced features of my database, especially PostgreSQL, and I've found that it's really easy to do with Rails.

The "Scopes" feature of active record that let's you save small snippets of a query and chain them together is fantastic. I've used it to create complex filter functions that combine full text search and coordinate distance as simple methods that can be attached to any query.

Being able to add a `.search("fender").distance_from(location, 5, :miles)` onto any query made my life so much easier.

It's been a few years, but I wrote about some of my favorites.

This isn't about laziness or the difficulty in understanding anything. There is a fundamental limitation of perception and cognition. Science can only describe what it sees. But it never knows if there is something important yet undiscovered that will change the analysis, because you just can't know what you don't know.

The universe is always capable of surprise. We are trapped forever with a limitation in what kind of pronouncements we can make about truth. The best we could ever say, is that something appears to be true today.

For instance, there is a chance that we are actually in a simulation -- that we're literally just a running computer program. If that is the case, the programmers of that simulation could change the instructions that control our physics at any moment. And everything that you have declared "true" will have to be reevaluated.

This might seem unlikely, but it is not impossible, and so science has to keep an open mind and hedge its bets when making any declaration about reality. Science can only give you a probability that something is true, it can not ever say things with 100% confidence.

You can literally write my_method = Kernel.method(:puts) and it’ll give you the method to do what you wish with.

As far as defining anonymous functions, literally all you have to do is:

my_func = -> (input) { output }

That makes a “lambda” which is literally just a function you can pass around anonymously.

You call it via either my_func.call(input) or simply my_func[input].

That capability is used all over the place.

Ruby absolutely has first class functions, the only thing you can say is it the syntax is slightly different if you want to use them anonymously (with no object context).
I've no clue whether Scott has turned into a misogynist over the past few years. (I think it unlikely, but theoretically possible.) I would assume, though, that he assumes that other people who say things that aren't inconsistent with his views while sounding like they agree with him are in agreement with him.

This is usually a reasonable heuristic, but it falls over when one person thinks “childhood malnutrition harms brain development, reducing intelligence, so improving the diet of poor children is urgent”⁰ and somebody else thinks “rich people are rich because they've earned their wealth because they're genetically really intelligent; it's social Darwinism”, but the only things the two are saying to each other are things like “poor people / members of minority ethnic groups score lower on average on IQ tests¹”.

---

⁰: I've seen Scott make basically this argument – though it was probably about intestinal worms rather than nutrition.

¹: Since I brought this up, I'm going to use the opportunity to suggest that Scott has, historically, put too much credence on IQ tests as a proxy for intelligence. I was basically tutored to be able to do well in IQ tests, as a result of my background, and I've never seen him take things like that into account – despite the decades of academic research backing up my anecdote (IQ tests are culturally-specific).
The problem is their opinion often aren't actually based on first principles. Humans have a strong tendency to form an opinion for various emotional and social reasons, and then build up a set of justifications ex post facto, often without realizing it. The more intelligent you are the easier it is to do subconsciously and it's often harder for your ego to admit the strong role your id played.
