Non-sequitur.

Quantum mechanics didn't require $10B (or whatever the equivalent would be in 1930-ish currency) to create. The "inventors" of QM were trying to explain measurements that were already made, quite inexpensively, that did not fit the model of nature that we had at that time.

Basically, the experiments were done, measurements made. Now the theorists were trying to understand what they needed in order to be able to provide a model that fit these results. This required a number of specific mental leaps of faith. Some of these are controversial even today. But they fit the experiments, so the issue for us is one of a mental model.

But ... and this is critical, not all of physics is quantum mechanical. Orbital calculations don't (normally) require QM. Steam engines, heat engines, etc. don't normally require QM.

The objections some of us have with classifying "all of physics being HEP" is that it is not, and the reality is that most physics do not require accelerators. Most new physics won't require accelerators.

A great example from earlier this year is the first sighting of a Majorana fermion[1]. Though this article also makes the mistake of "In particle physics, fermions are a class of elementary particles". Its not in particle (HEP) physics. Its in physics.

>> When you choose something, dont quit when you start to doubt if theres a better way. You aren’t actually equipped to make that evaluation until you have tried and succeeded/failed with your current path.

This is something I learned from my former boss (director of research): Don't try and evaluate your experiment before it's finished. See it through before checking your hypothesis.

In the case of local councils there are a huge number of improvements they could do locally. Roads, parks, community centers, etc

Now, I know this isn't really the place for a lecture on economics but I find this model of economics very unintuitive. Surely the inheritors of the estates of these elderly people will also have plenty of demand for many goods and services? I certainly could do with a cook and chauffeur. A trope of dancers wouldn't be ammiss either. If I promised to spend the savings of these deceased people on cooks and dancers, would you be happy with that money falling to me to keep demand constant?
Yep. This is called seek vs scan. It's a common issue when you start hitting 10's of thousands of records.
What's fascinating about this is that the home computer "revolution" could have started a few years sooner had people just realized they could make a CPU out of 33 74xxx series IC chips. These were relatively low cost by the early to mid 70s. It took a generation of skill to go back and see what could be done with just these logic building blocks.
The section on Lamba missed the biggest problem: latency and cost.

For low regularity calls, Lambda suffers badly from the cold start problem. The first call to Lambda must actually create the lambda which can take hundreds of milliseconds. This problem also shows up when the level of requests exceeds the number of lambdas currently active, causing a cold start as the new lambda instance is created. It’s not uncommon to see some services inject fake requests with some regularity to insure that there are enough warm lambda instances to avoid the cold start problem, which is silly.

Secondly, all lambda calls are charged by the millisecond, but the all calls are rounded up to 100ms. So if your typical lambda call is 5ms, you might be paying for 20x more time than you’re actually using.

Both of these issues led my former team to use a regular ECS app rather than lambdas.
io_uring requires userspace to access it using a well-defined load/store memory ordering. Care must be taken to make sure the compiler does not reorder instructions but also to use the correct load/store instructions so hardware doesn't reorder loads and stores. This is easier to (accidentally) get correct on x86 as it has stronger ordering guarantees. In other words, if you are not careful your code might be correct on x86 but fail on Arm, etc. Needless to say the library handles all of this correctly.
From the paper:

>However, the .01 c mission sketched in [10] has a spacecraft mass of only 6.6 mg, divided between the sail and the payload. Multiplying this by 100 while keeping the sail mass fixed leaves a payload mass of barely .65 grams.

Oof. That's not a lot.

Oh don't trouble yourself on my account. I have no urgent use for it, so will just wait for it to be done properly.

And you're right about the percentage field. I didn't notice that 9% was correct for that field rather than 0.09.
What truly boggles my mind is this:

* Personal consumption expenditures constitute 67% to 68% of US GDP every year: https://apps.bea.gov/iTable/iTable.cfm?reqid=19&step=3&isuri...

* Business revenues are the flip-side of those consumption expenditures, because every dollar consumers spend, to a close approximation, is a dollar of revenue for some business -- whether it's your Aunt Tilly's burger joint, your local movie theater, one of the airlines, a downtown hotel, an amusement park like Disneyland, a retailer like Neiman Marcus, and yes, Amazon and Google too. So, 67% to 68% of US GDP every year, give or take, is made up of business revenues from sales to consumers.

* If consumer spending in the US collapses by, say, 30% (a figure I've seen in some articles), business revenues from sales to consumers in the US necessarily declines by a similar magnitude at the same time. If two things are near mirror images of each other, and one declines 30%, the other declines by a similar magnitude too. For every expense not incurred by consumers, there's an equal sale not made by some business.

I don't even know how to reason about the impact of a 30% collapse in business revenues across the entire country.

Except you don’t know whether the neighbours house isn’t on fire, so you had better go in just in case. And while you are there, take an inventory of everything you find, record the data forever for unknown future purposes, and then never leave. It is not a valid comparison.
I want to believe in ActivityPub, because it has traction and seems to be doing this federation thing very well. The problem is that ActivityPub is not a protocol, it's a framework for building protocols... The spec is voluntarily vague and allows for "undefined behaviour". The issue is that you can't "implement" ActivityPub, you can implement something that respects ActivityPub but will be incompatible with another implementor's vision.

There desperately needs to be more work on writing down what platform does what, and remove all duplicates because it's not a viable path.

Writing a SQL database from scratch in Go: 4. a database/SQL driver
I think it is a cultural thing. I am Indian living in US. 32 years old, married and my wife and I live with my parents and we couldn’t be happier. I will always live with my parents.

Now this of course varies from culture to culture and household to household.

We are very very happy and our kids always have grandparents around in the same house (big house - it matters).

We get unsolicited advice and counseling from our parents ALL the time. Sometimes we hate it and sometimes we appreciate it. We disagree over many things and don’t see eye to eye on many small issues. But on a macro level, we are aligned.

Now that we are all working from home, my favorite part of the day is the morning where we all sit down and have a cup of chai made by whoever happens to be in the mood of making that day. We are a solid team and we all play a part in making each others’ lives better.

I have always wondered about how our kids will be when they grow up. I am not going to expect them to live with us and I am going to prepare myself mentally for that. But by God, it would be a blessing if my kids and my wife and I live together forever just like I am with my parents. Nothing would make me happier to live my life in a smooth continuous gradual way, rather than big disparate phases where kids move out, we live alone, we get very old, someone takes us in and take care of us until we die. I am scared of that.

It can be reshaped, but the plastic will not have the same mechanical and optical properties as "virgin" PET, so it can't be used for the same applications.
It only destroys the goods if you let them soak in the solution for hours. How does that make it dangerous? If someone wanted to just destroy goods, fire is way more effective.
The opening of doors prior to having you make your decision is a red herring. The person opening the doors knows which one the prize is behind, and they’re only going to open doors which have no prize. So if there’s 1000 doors, you have a 1/1000 chance of choosing the correct door, and there’s a 999/1000 chance that the prize is behind a different door. So if the host selectively opens 998 losing doors, leaving your original selection and one other door closed, there is still a 999/1000 chance that the prize is behind the door you didn’t choose. If the host instead opened the doors randomly, there would be a 998/1000 chance that they’d reveal the prize before narrowing it down to the two doors. But they don’t open them randomly, which is why the door opening doesn’t matter. You’re effectively being given a choice between the one random door you originally chose, or every other door.
It’s probably our respective filter bubbles, which is a whole other problem

I just spent 20 minutes browsing your site, revisiting these epic scenes. Thanks for sharing!
In another comment on this thread they explained that space and time are parts of the same vector, <x, y, z, t>, with velocity being the speed of light. Here you mentioned time is frozen at the black hole event horizon - does this have to do with the theory that we can use black holes as "portals" to distant parts of the galaxy? So if time is 0 and we have <x, y, z, 0>, does this mean we travel at the speed of light?
My point was that great literature doesn't need the involvement of 90% of the population to exist.

If 90% of the people stop reading books "deeply" (and that's assuming they ever did), we still get to have Tolstoys of our day for the people who want to spend their time that way. This is no loss for humanity.

You picked "reading books" as your metric of progress, but that choice needs to be justified. If, instead, you picked "watching programmed television", you could be similarly concerned as more people are cutting cable, but fewer people would take this argument seriously.

Thanks I didn't know this. I just looked up since when PowerPc 64-bit is a think.
Thanks a ton for the detailed feedback. You are right about all of the feature expectations. This app is a product of 2-nights worth of work. We'll keep on progressing it further.

- Active/passive filters mean "still ongoing offers" and "responded offers" but I see why that might not be obvious.

- Can you elaborate that subtotal part? I'm not sure what you mean.

- We are thinking of payment processing, but that's not an MVP-level feature in my mind, so that feature needs to wait a little.

I recently hit a reCAPTCHA while trying to edit a ticket on one of my projects hosted on Gitlab.com. Since I block reCAPTCHA, this was silently failing and I had to debug this. This prevented me to edit this ticket. This is bad.

I initially chose Gitorious when I needed to share an open source project because it was free software. I've been transfered to Gitlab.com and was ok with this back then.

But requiring me to run this piece of non free tracking malware and solve a captcha to manage my free software project, and worse, making me force this upon the contributors of my projects? This is bullshit.

I know the Gitlab staff is on HN, so thank you for your amazing software and for the free hosting, but be aware that this is making me move as soon as possible and actively discourage people from using Gitlab.com. ReCAPTCHA is not OK. Never.

Cloudflare made the move [1]. Will you?

First off, I don't understand how my stance is "speculation", but yours is not.

> Well arrays are bounds checked by default in Rust, so you can't do that one.

But that's my entire point. If you're observing a benefit here, it's decidedly not due to the wrap-around, but due to other features (like bounds checking), and the argument should be that those features make Rust better than C++. It seems strange to give praise to the multiplication wrap-around instead.
I don't have access to the article right now either, but I would like to note to the "this enzyme is going to eat all our stuff!" commenters that, in general, most enzymes don't work very effectively in ambient conditions. The abstract doesn't go into detail into how they acheived the "90% in 10h" metric, but I would assume this was in a precisely controlled solution, incubated at an optimal temperature, with fresh enzyme that hadn't had a chance to start denaturing. You aren't going to be able to spray this on the plastic siding of someone's house and watch it wither away (even if home siding was PET and not, IIRC, vinyl or something.)

I guess I can't rule out at that some recombinant bacterium expressing this enzyme might escape the lab and start causing PET objects to get moldy or develop a patina if left out too long [0]. But that would require that this enzyme somehow benefits the bacterium enough that natural selection wouldn't favor dropping the gene for it.

LEP was annihilating electrons with positrons; LHC does not, as it only accelerates protons. FCC will have the option to do both: the plan includes two separate pipes in the same tunnel, one for protons, one for electrons.

This however does not increase the collision energy significantly: a single electron-positron pair has the (rest) energy of ~1MeV -- this is what is released during the annihilation, but the energies we want to go to at the next collider go up to 10TeV, so 10^7 times larger.

Something I would like to see is Prolog/logic programming embedded in a general purpose programming language, rather than as a standalone system.

Racket and Perl 6 are the only small userbase languages in the last 8-10 years to amaze me with their feature sets and to make me want to learn them just for the sake of experiencing them.
I'm sorry, but I disagree with the label "fundamental" here.

One can observe anti-de Sitter spaces in superfluid systems. Is that not more "fundamental" than zoology of particles and their interactions? That has, literally to do with the metric tensor of space. Seems to be a bit more fundamental to me than things interacting in that space.

Put another way, the "fundamental" argument is very weak, and everyone outside of HEP knows this.

Really cool. The iPhone replaces the touchpad since it already has a great touchscreen. The MacBook can be much more affordable because it doesn't need CPU/GPU/memory/wifi/bluetooth anymore (assuming if it uses a wired connection to communicate with the MacBook).

Love using Docs as a source. A while back I wrote a service[1] which creates an API using Google Drive and Docs as a source. Docs are naturally pages, and the Drive folder structure builds the hierarchy/tree of pages using a pretty simple naming convention (Mainly for ordering). The CMS/collaborative aspect is great. Some things that aren't ideal are:

- Seeing print-style page breaks in docs
- Formatting images. Although, having Google host them is nice
- The html Google Drive generates is inlined, inconsistent, and pretty nasty. I resorted to using markdown in Docs.

The exciting thing is that there is real progress in increasing temperature stability of enzymes. That's the point of the article, engineering an enzyme that is still active above the glass transition temperature of the substrate. I remember a paper where they tried random mutations all over some enzyme, it was just mindless make-work for an army of graduate students. This one is different.

Traders can certainly spread their bets across many companies representing a business sector, and routinely do so. This "a few firms might go bankrupt so this explains why entire sectors experience massive volatility that isn't justified by long-term revenue expectations" claim seems like someone trying to rationalize irrational human behavior.
It's worth calling out here that for games that maintain a steady 30 Hz flicker (very common on NES, and even carried over to SNES in a few titles) played on an original CRT, the effect really works quite well, in part due to the slow response time of the hardware, and also in part due to persistence of vision. On most real CRT monitors, a properly rendered 30 Hz flicker (ie, when the game isn't delaying frames due to lag) closely approximates a 50% alpha blend against the background. This was often confounded on NES due to the 8-sprites-per-scanline limit, so your memory of Super Dodgeball's "flickery nightmare" is accurate.

A modern flat LCD panel has a much faster response time for the individual pixels, making the effect seem harsher even when the software works correctly. Complicating matters, many emulators of older game systems struggle to push out exactly 60 Hz (sometimes on purpose, to correctly simulate the original hardware's non-60 Hz timings) which can introduce additional artifacts and make the result look messy.
Yes, Android Studio (and the emulator)

The Android app development went from my first laptop with 4GB RAM and HDD to my second laptop with 8GB RAM and HDD to my current, third laptop with 16 GB RAM and SDD.

Or government response isn't the reason for the difference.

Japan's government didn't respond quickly to COVID-19 (some have even said they actively tried to downplay it to protect the Olympics) and yet Japan has very few cases.

Perhaps the difference is cultural, or geographic, or travel patterns, or something else entirely.

Thanks for the response! I guess my issue is that there's no actual value in owning non-dividend shares for any amount of time. So I can sell the stock to someone else, but what are they paying me for? The opportunity for the value to increase more? Why is someone interested in paying me more than I paid? I feel like there's never any real money that's made back by owning those shares. What's the goal?

Removed from the stock market, if I privately invest in a company for $1m for 10% of the company, it's because I'm hoping that someone else will see that the company has value and purchase it, giving me 10% of that future purchase price. The company sells a product of some sort, and I have a 10% vote in what they do with that money, which I'm hoping is to sell to a larger company.

Is the goal the same on all of these non-dividend paying companies -- to be bought by a bigger company? Because otherwise there's no value in the shares except speculation itself, which seems pointless to me
