I'm pretty sure the exercise was to show the absolute extremes that could be achieved in a toy application and possibly how easy one could achieve some level of IO blocking scaling that has been harder than most other tasks in java of late. More and more, heap allocations are cheaper, often with sub-milli collector locks, CPU scaling has more to do with what you're doing instead of the platform, but java have enough tools to make your application fast.

For extremely IO wait bound workloads though, there was always a LOT if hoops to jump through to make performance strong since OS threads always have a notable stack memory footprint that just doesn't scale well when you could have thousands of OS threads waiting around just taking up RAM.

"Not a whole lot to show" from the LHC? We got the Higgs Boson, and piles of data providing more accurate measurements of fundamental constants in the Standard Model, along with a ton of progress in various "applied" areas related to developing the materials/tools for constructing the thing.

There's a good reason Gurobi is so expensive, and the company hires so many stellar optimization experts. Building a top-tier solver is hard, and short of a paradigm shift I don't see this as a realistic timeline given the low funding they're asking for, and what I've heard about previous attempts to match Gurobi with far more funding.

If this is your first time reading something like this, you need the obligatory structure. If you already know everything, it's not for you. If it's complicated and normies can't do it, that can't be helped, it's what we have. If you are a normie looking for privacy and see that it looks unintelligibly difficult, that's educational. You might be upset by that fact, and therefore support and amplify criticisms of the current regimes, software that simplifies the process, and/or legislation to protect people.

I’ve been impressed with Google’s OR-Tools CP-SAT solver which is free to use. I think I will need a good reason to us something other than a satisfiability solver on most problems. It’s a bit like the Pareto principle. You can spend a fraction of the time running a sat solver and get most of the benefit of trying to find the optimal result.

I nevertheless object with a side reasoning: costs are complex beast, in an age of scarcity, where oil is pushed aside no matter if for good or bad reasons, how costs can change?

I mean: maintaining an aerial network and relevant trolleys is surely expensive, but expensive in what? In natural resources or in worked hours q
and hour of vehicle mandatory stops? If it's just in worked hours/maintenance time than in the aforementioned age of scarcity such cost does not matter much.

Few marginal notes:

- at page 77 the graph 5-35 show a curious cost per km change in late 2008, why? Is this due to aging or to purely economical factors like supply chain changes for spare parts, safety norms changes etc?

- the ability to roll and change routes without capital infrastructure set up will be king is another complex beast: on scale that's the reason many researchers try to push naval and very-short-range aviation, from flying taxis to city-to-nearby-city small scale logistics: STOL/VTOL have almost the same industrial cost (beware, industrial not price tag on sale) than modern cars and vans, they cost more in opex but new physical road/rail infra development and regular maintenance/changes cost skyrocketing high capex for an uncertain future since they demand 10+y just to be finished on scale and they need 30-50+y to be paid back enough. At city scale though maintaining a complete coverage of a municipal aerial electrical grid for vehicles especially if we ALSO open if to future other transports (like food distribution logistic till even private cars) might be sustainable. Not in today economy, but in the new world one. In the end actual cities are not sustainable already, we figure out new smaller cities that look like much to small factories with workers inside also for this issue...

- with actual battery chemistry we simply can't sustain a real BEV fleet, we can't produce enough batteries for a new FIRST generation of vehicles nor we know how to recycle them to having enough resources for the next generation in just 5-8 years. BEVs can be done for a small scale of private vehicles, mostly targeting wealthy people + some "glorified golf cart" [1] for specific short range usage...

I was applying Occam to myself as a meta-researcher (I like that term!) not to “scientists”. I will happily assume there is a wide range of literacy among scientists, and that it wouldn’t take many positive results for research on thymalin to start ringing bells. I will also admit to the assumption that Russia cannot possibly be the only place where there is a high degree of willingness to experiment aggressively with , on, or on behalf of people who are running out of time. China seems like one place. India. Indonesia. It’s very difficult to see how real progress in this field wouldn’t be publicized.

As an aside, may I suggest to you that in a forum with many Americans, use of the word “retarded” will usually get you a very strongly negative reaction and obliterate consideration of any other points you may be making.
> There's an example too, but this could use more emphasis.

To be fair, handling lambda cold start is AWS lambda 101, and initialization is the starting point. I'd say that the only people not aware of this is those who are just taking their first steps.

This requirement is even notorious in JDK lambdas, and leads to the need to use dependency injection frameworks to handle initialization and consequently favour compile-time dependency injection frameworks such as Dagger over runtime ones like Guice.

> things that could be safely cached in a hashmap, etc.

I'd add that caching data in /tmp to get it through lazy evaluation is also a quite basic technique. The contents of /tmp are preserved between some calls and checking if the data is still there is an effective technique to shave off some milliseconds.
Windows does not allocate handles sequentially, and I've seen this pop up as a race condition and bug. I don't think changing the way they're assigned is necessarily good enough.

Twitter is more like hooking electrodes to a the brains of a frog and watching parts of it jump when you apply current.

The people worrying about Musk: (a) believe that twitter offers such zombie like control over "global consciousness", (b) that such controls are a good thing, and (c) that Musk is the Wrong Person to wield them, which means there must be Right People somewhere.

I think they're wrong on all counts.

It was only last week I made a submission about porting a trivial text-adventure game (which I wrote) from CP/M to the ZX Spectrum.

The features I have available are laughable, even basic things like entering text have to be done "by hand", no readline, no sounds, and doing everything manually is a recipe for confusion unless you're very careful.

Still fun to play with such machines though, even now, and some of the games hold up pretty well even if we ignore the nostalgia component.

> string theory this and god particle that, and it's really not very satisfying or illuminating

I think what would be interesting would be a study of why researchers are drawn to string theory. I remember reading about it in OMNI magazine as a teen back in the 80's. During my studies at university, I learned about many proposals in physics that failed after people spend decades trying to hammer into reality (like the electrical ether, or planetary motion), only to have a genius show up and resolve the dilemmas with a completely different proposal. Going on its 5th decade, string theory feels like one of these ancient red herrings, but maybe it just needs a few more centuries?
Weak research, I have at least 4 out of 10 in my dice collection, some improved (my "d1000" set has 10 or 11 digits, newer and rarer d100 makes in addition to the old Zocchi patent, both d4 numbering schemes...).
I just started watching (and enjoying) Sabine's YouTube channel after one of her posts were shared on HN the other week.

I am surprised to find so many people here have negative opinions on Sabine. I've probably seen a dozen videos about the double slit experiment but her explanation about it (and why the other videos were not precise/accurate) was really eye opening for me as a layman. Also her explanations about delayed observer not being as "weird" as people claim was also very helpful in demystifying quantum weirdnesses.

She seems like a competent physicist with strong opinions that are grounded in some basis - can someone elaborate why they don't like her points of view? Are they problematic scientifically or do they just not like her style of rhetoric?

We don't need accountants and lawyers just to live our lives. We don't even need them if we have a well paying job, a mortgage, a fulfilling long term relationship, and a clutch of progeny.

But we do need them to run a business, because --and this is the part that explains why-- your brain is finite, and you cannot be an expert at accounting, and law, and your actual profession. The willingness to outsource expertise to other people is what makes society possible.

As for calling income tax a punishment: that's a bit weird, because you're not paying taxes on "your money", your money is what's left after taxes, the amount before taxes was your employer's money. Only some of that is going to be yours. If you live in the US, you unfortunately live with an idiotic system in which you are handed the full sum, being way more than is actually yours, and then making you responsible for splitting it up correctly and punishing you if you don't. However, if you live in a more modern country, at least in terms of how tax is handled, you wouldn't need to do this at all. The taxes will be withheld as part of the transaction, paid by the party doing the paying, and what is received is 100% the receiver's money, with no further taxes owed. (we see the same idiocy vs. sensibility with sales tax: some countries like Canada or the US have the insane habit of listing untaxed price in stores, with an inflated price at the till. More sane countries instead list the actual price of goods, with the tax processing taking place in the computers that handle the payments)

Remember: your country needs to make money for it to stay a country. Setting a rule where any monetary transaction taking place in the nation (made possible only because there is a working national economy in the first place) has to include a portion that gets used to fund the nation that makes the economy possible isn't too crazy. Sales tax, income tax, capital gains tax, etc. are basically all the same thing (money changes hands, the nation gets a portion of it so it so that it can keep operating) using different rates (mostly) adjusted to be appropriate to how much is necessary to prosper. Of course, in a good tax implementation, you don't "get that money and then you have to pay taxes", instead those taxes are withheld as part of the payment and when the tax date rolls over, you have nothing to do (something that a number of countries actually do).

It's when you get into levies (property tax, fuel surcharges, etc) that things become a bit more questionable, and one of those "what kind of country do you live in" differentiators.

To add onto this, first start with the premise that you don’t have to do anything at all in life. You can be a bum. Sure it would bother some people but it’s true.

Then spend a few years thinking about things that are truly worth doing. Long term goals that truly excite you which you can build towards.

Don’t do anything just because. Only do things that give you joy or are towards a goal you find exciting. Life is short and don’t waste it on pointless tasks.

This is how I personally found more motivation.

The fact that Visa and Mastercard have these great margins is entirely down to their duopoly. In a competitive market the fees would be massively lower because it's not actually that expensive running the network. 2%, think about that! With the amount of transactions they do they're printing money. You're paying for this, it's your money and that of every other person, even those who do not use the companies, because the vendors pay the fee. That's the genius part of their model and since most people don't care about finance they don't understand how they're being ripped off.
In the South, yes -- air conditioners are definitely the biggest cost we have for electricity.

I do feel that hempcrete would be a good building choice for a lot of places in the US, based on insulation capacity and relatively low cost of materials.

But the cost of labor to build with it would be higher, due to lack of familiarity with the materials, and it would take longer to build with -- especially compared to prefab or other higher speed building methods. And then there's the increased cost in labor to do the interior fittings.

I am a fan of hempcrete. But it will take significant adjustments to the building process here in the US.

That sounds like you are complaining about the amount of investment in experimental physics in general, rather than the LHC in particular. It is true that fundamental physics could use a major breakthrough from the theorists. However, the theorists we do have are desperate for more experimental evidence to help them.

Add to that that experimental physics is simply far more expensive then theoretical physics, and it should come as no surprise that we spend more money on experiments then pure theory.

The complaint about LHC is more about questioning weather spending $5 billion to smash protons together is the most effective way of getting more empirical evidence to the physicists.
[..]The treerooms have no sewage system and eco-friendly products are used when cleaning. Each has a modern, environmentally-friendly and completely odorless combustion toilet where everything is incinerated at 600°C using electricity. The Mirrorcube treeroom, on the other hand, has an electrically-powered, odorless freezing toilet. Bathrooms feature water-efficient sinks with enough running water for washing hands and face and brushing teeth. All wastewater is collected in a container that is emptied daily, while showers are located in a separate building. No drains are placed affecting nature adversely.[..] This is the bit that I found interesting and ended up at this forum: https://forum.susana.org/141-other-types-of-toilets-and-sani...

The amount of water used for flushing human waste(around 10k liters a year) that can be saved with freezing toilets is enormous. Energy cost isn’t much compared to our current sewage systems. Composting is important.
No, never. SQLite is one of the things I use most. Similarly, I respect the project and developers behind it a lot.

On the other hand, I don't accept calling something damned because it's old, or has quirks or both. This is the same API (and set of standards) I work with, and I had my fair share of problems with it too.

However, I accept that no API/Standard is perfect, and work my life around it. Also we have a huge ecosystem built around it, and while it's not perfect, it's working so far.

And yes, I refuse to give my freedom to make errors, crash and burn spectacularly in the name of ease of use and abstractions. Because I need that performance, and want to be able to reach to hardware without all these layers and safety nets.

We have abstracted safety nets above POSIX level, and anyone can use that if they want.
> Because for most people privacy on the internet isn't important.

This is untrue and the only place I see people claiming it's true (ironically) is here on HN. Privacy is intentionally made as difficult as possible when using anything where control could conceivably be centralized. These services are also made crucial through the elimination of others that are more privacy-respecting. In the case of the internet, this is inevitable because internet business don't have to make a profit, and they destroy the previous businesses that did.

I don't meet anyone who doesn't want privacy as the default. It's weird to even have to say that when Snapchat is winning among the generations that get most accused of being comfortable with this corporate and government-imposed lack of privacy.

There's a specific figure of speech related to this claim that kind of irks me: when someone says that they "choose to believe" something.

Really? You can choose to believe something? I'm really not sure I can. If you really think that you can, try an experiment like this:

1. Look closely at something familiar--maybe your car or your house, for example. Identify what color it is, or what colors predominate.

2. Now turn the other way so that you can't see it. Choose to believe that it's a different color.

3. Turn at look at it again. Are you surprised by what you see?

The vast majority of people I’ve seen using neopronouns, or “it” or “they” pronouns (either exclusively or alternatively with classical gendered pronouns, e.g., “she/they”) have nonbinary gender identity or agender identity, and the vast majority of the exceptions are trans, and all the rest (i.e., the cisgender ones) I’ve encountered are one of bisexual, pansexual, asexual, or same-gender attracted, usually also with gender non-conforming presentation.

I have yet to encounter a cisgender heterosexual with nontraditional pronouns for their gender, though I am sure there are some somewhere doing it.
