Don't get hung up on 'pain perception', my point sits at a higher level of abstraction. It has very little to do with biology, more to do with topology.

If 'events at point_a' gets consciously interpreted by participation of cells one of which, lets call it point_b, is singularly dedicated to sensing events at point_a, we have a mapping in a mathematical sense from point a to point b. We know all such point_bs form a strict subset of the body, a part of the central nervous system.

If this mapping is continuous in the mathematical sense and a contraction, then a fixed point has to exist (a location that does its own interpretation). But the fixed point seems biologically implausible, that leaves us with the alternative that there has to be dead-zones -- places where events can happen but cannot be interpreted. (Example blind spot in the eye)

The way to avoid dead-zone would be to break continuity, or contractive property of the mapping.

> I am sure you could find an example … of a creature which has pain receptors in the brain …

I think my point would be easier to state for this hypothetical creature. If interpretation of pain is done by a strict subset of its cells and there is a one to one mapping -- at least one location b that interprets pain occurring at location a exclusively (presumably that's how the creature knows the pain is at 'a'), can this creature be free of dead-zones if the mapping is continuous and contractive. Can any creature free of dead-zones exist under those conditions. You claimed 'why not'. I am saying that if the mapping is a continuous contraction then either there has to exist dead zones or there is at least one self interpreting location.

To give another example of this phenomenon, if you spread the map of your city somewhere in your city, there has to exist at least one point in the map that sits exactly above the point it is representing -- the fixed point. The way to avoid this would be to have 'tears' in the map, or to have points in your city that are not closer on the map than they are in the city (that would be an unusual map).
Sorry, but this is BS. The course of a river is a direct result of several close-to-deterministic forces and influences. Caesar's Palace, along with "neurobiology, economics, and regulatory regimes" are manifestations of many different forces, a large number of which are subject to individual and social choice-making. The pretense that "neurobiology is destiny", "economics is as immutable as physics" and "regulatory regimes are natural law" is just completely bogus, and the argument is one entirely in favor of the status quo, by the status quo.

One scientist said it looked like it came from a lab and all the reactionaries latched onto this one statement as if it was the real truth being hidden from them. They promptly ignored when that same scientist admitted he overstated his position because that conflicts with their world view and censorship and persecution complex.

That's a bit of stretch, I think. I got my Tinnitus after my Cuba vacation too and I've seen some salsa practices when I was there however none of those had a loud music. I'm not into DJs and my only attempt to trying to get into a venue with a DJ ended with a frustration after giving up waiting in the lane to get into the Cave club in Trinidad.

Also, later I found out that my tinnitus is due to my unhealthy sitting position when using a copmuter that apparently was not so good on my neck.

> A 2019 US academic study found "brain abnormalities" in the diplomats who had fallen ill, but Cuba dismissed the report.

As did a lot of academics:

"The latest brain scans may provide fresh evidence of some injury, but the study was not without critics and some researchers have questioned whether there was any kind of attack at all.

“Finding evidence of brain change doesn’t provide evidence of brain injury or damage,” said Dr. Jon Stone, a professor of neurology at the Centre for Clinical Brain Sciences at the University of Edinburgh, who was not involved in the study.

Dr. Sergio Della Sala, a professor of human cognitive neuroscience also at the University of Edinburgh, in an email called the study “half baked.”

He noted that 12 of the affected workers who had a history of concussion prior to going to Cuba were included in the analyzes. “In comparison, none of the controls declared previous brain injury. This in itself could cause statistical group differences,” Della Sala said."

GC pauses are not the only GC issue. Thrashing the caches and blowing up memory usage by an order of magnitude can be also very bad for performance. In a database system memory is very precious - the more of it you can use for caching / buffering users data, the better the performance.

As for the subsecond spikes in latency, these tend to multiply in a distributed system. If serving a client request takes N internal requests, the likelihood of hitting a GC pause somewhere is much larger than if you did only one local request.

Not sure about Go, but none of the "free" Java's GC guarantees low pauses. There is STW fallback even in the most advanced ones like ZGC. So you never know when it stops for more than 1s.
The OS paper maps are still very popular these days but have managed to destroy both the paper and weatherproof ones over my time.

Also very easy to lose a map, the nice thing about phones is everyone else you are with is carrying one, less so with maps. The only real way you are going to get everyone in a groups phone breaking is if you are somewhere extremely cold.
this is incredible. I mean, I have fond memories of playing Tie Fighter (until a glitch with the floppies and an upgraded PC meant I couldn't install it again!!), I don't game or follow retrogaming land, so what is the background here:

What is X-Wing Alliance? Someone 'out of nowhere' (is the code open sourced or something) decided to redo all the engine/graphics to be 'modern'? It's incredible to me that this could exist/that someone put that much work into it. If the code is open, is it a matter of simply updating the engine and then replacing all the 'sprites' and textures with updated stuff, so really just a massive graphics update?

> The institution originated in Italy in the fifteenth century, where it gave poor people access to loans with reasonable interest rates. It used funds from charitable donors as capital, and made loans to the poor so they could avoid going to exploitative lenders. Borrowers offered valuables as collateral, making the mount of piety more like a pawn shop than a bank.

So the Belgian one is still running. Acceptable collateral [1]:

Jewellery, precious stones, and gold

Luxury watches, gold pocket watches, and antique clocks

Luxury leather goods (handbags, belts, etc. - certain brands only)

Comics and collected editions, and derived objects

Paintings

Objets d'art, sculptures, ivories, bronzes, and porcelain

Silverware

Glassware and crystal bearing a recognised mark

Coins of numismatic value

Wines and spirits of exceptional quality

High-end bicycles in excellent condition

Musical instruments

Now, i didn't grow up poor in Belgium, but these don't immediately strike me as the kind of things that the credit-hungry poor are likely to have lying around the place in any great quantity.

Incidentally, this was an interesting list to translate (with machine help!), because there are some expressions that don't have really good equivalents. The French version distinguishes "montres de poche" from those "à goussets", but i think a gousset is just a particular kind of pocket. I'm not entirely sure what "livres de collections" are, but in context it seems to mean fancy hardback editions of works, like those put out by the Folio Society [2]. Tableaux are paintings, not tables, Google. Cristaux signés seems to mean glass crystal items marked by their manufacturer - apparently British crystal is marked like that [3], but i've never heard anyone be concerned about it - and it seems to be a metonym for high quality. Similarly, for bicycles, "de marque" literally means "branded", but here i think it has a connotation of being made by a fancy manufacturer (Rolls-Royce is a marque, Vauxhall is a make!).

I was mostly just reacting to suggestions that paper maps are unnecessary. I actually agree that you don't always have to be fully prepared against any possible eventuality, however unlikely. And that carrying too much stuff can be a hazard on its own.

I've walked hundreds of miles in England and I've always carried a map with me but I've almost always used the OS app and the paper was mostly for planning and getting a bigger view.

I am suspicious of electronics. This just seems like a case where, given the easy backup, why not use it when it might matter.
I don't tend to experience hunger and, as a result, interrupting my activities to eat multiple times per day can feel like a bit of an inconvenience. So I've frequently fasted daily since before "intermittent fasting" entered the common lexicon. It's not really intentional though, I will quite literally forget to eat or otherwise just don't make it a priority.

In my experience, I'm not sure it's quite the panacea it's sometimes made out to be. Perhaps there are psychological benefits to intentionally fasting that I'm missing out on. In any case, quite often when I'm wondering why I feel like shit I end up realizing something like I haven't eaten in 24 hours or in the last 48 hours I've eaten less than 1000 calories. Oops. I'm trying to be better about regularly eating 2 meals per day because I really do feel better if I've been eating consistently.

I'm not sure it's doing my blood pressure any favors either. Despite regular fasting and having a BMI of 18.1 (technically slightly underweight, as the lower bound of a "healthy" BMI is 18.5), my blood pressure is usually around 140/95. But who knows, maybe it would be higher without the fasting.
It seems like the real problem then would be that managers don't feel like they can evaluate trustworthiness without in-person interaction or a pantopticon.
why are you lying about entire districts being burned down by BLM? Surely you can provide some actual evidence as to this happening. Right now is just looks like more completely unsupported right wing hysteria.

You make good points: the barriers to entry have dramatically decreased across a huge portion of the stack. With one notable exception: the cost and complexity of modern fabs increases every year while the companies involved consolidate or die out.

tsmc could easily decide “we’re not gonna fab your RISC-V design” at any moment and you’d be more or less SOL. I mean, you could fall back to a 150 nm process, but that kills a lot of opportunities.

And if things continue — if Apple, Amazon and Google move further in the direction of custom silicon — this will happen. Apple already has a pretty big advantage with their custom silicon — which they don’t sell for use in non-Apple products. Now just imagine if they brought tsmc in-house and had exclusive access to the most advanced fabs on the planet. Your ability to compete, and the room for people to build GPC would constrict MUCH further.

We have this enormous, all-pervasive stack built upon a foundation of like 3 companies, in the midst of massive consolidation. I honestly don’t understand how so many people who think about that are comfortable with it.
Out of 10 who say they'll quit maybe 1 actually will. And when they do there will 1000+ waiting to jump at a chance to work for Apple - under ANY condition.

How is this any different than how the US maintains its empire now?

David Brooks' column in the NYTimes this week is the same thing - using the excuse of LGBT rights to justify American colonial projects in Iraq, Afhanistan and Palestine, with an eye on Iran, China and Cuba. Use force to show the savages how it should be done. Empire has always been forged in the name of social justice. See the (racist) 1899 political cartoon, "The White Man's Burden."

As I read Adolph Reed say recently, ideology is the mechanism that harmonizes the principles that you want to believe you hold with what advances your material interests.

I think it is also interesting why people agree to work for the fraction of value they create for the company. Somehow this kind of suffering and exploitation is socially acceptable. Companies make billions and workers struggle to put food on the table.
I think governments should focus on companies avoiding tax rather than taxing them though workers (as workers suffer and yield is fraction of what companies should be paying) and we should look at tying minimum wage to company revenue (with a nationwide minimum, so that worker always gets paid a wage they can live off).

> Because "just rewrite your program in C to avoid GC pauses" is such a flawed argument

False. All popular databases are written in C, and continue because of the GC issue. I would not use a general-purpose database written in Java because of GC, for example. We'll see how well Go works in practise.

> sub second spikes in latency

Go is supposed to be sub-second GC pause latency, but understand that most SQL queries are sub-millisecond, so GC latency is still a significant issue compared to query times.

Go might be acceptable now for niche databases like column-store for certain use cases, though.

Also, see the excellent comment above about distributed systems and server cache issues. You can't do application performance analysis with GC literally everywhere.

The puerile knee-jerk hatred for C on HN has to stop - almost every software you use is written in C, from scripting languages to operating systems to web servers to databases.

Source: DBA who's worked with current databases, as well as a custom database written in Java with significant (ie. brutal) GC problems that required a total refactor (rewrite) to "work" at all.
The best thing about moving to remote work is that it will enable people to live in these smaller communities while having the increased income of the city. I hope this will bring more money back to local economies and revitalize rural areas.

Seller satisfaction will be the highest if the user buys the item. Basing the recommender on sales will make it a seller-focused recommender.

If the recommender somehow can be based on buyer satisfaction - it would be a system that focuses on the buyer. It would then perhaps not please the seller.

Taking it one step further, if a buyer is VERY satisfied, the buyer is likely to return for MORE purchases, ensuring the satisfaction of BOTH seller and buyer with the first recommendation. This is the ultimate recommender, measuring not first-purchase buyer/seller satisfaction, but rather measuring "so satisfied with the first purchase that the buyer returned for a second purchase".
