> absolutely no reason

There is a very good reason:

> Results show that the average risk of severe injury for a pedestrian struck by a vehicle reaches 10% at an impact speed of 16 mph, 25% at 23 mph, 50% at 31 mph, 75% at 39 mph, and 90% at 46 mph. The average risk of death for a pedestrian reaches 10% at an impact speed of 23 mph, 25% at 32 mph, 50% at 42 mph, 75% at 50 mph, and 90% at 58 mph. https://aaafoundation.org/impact-speed-pedestrians-risk-seve...

And this understates the difference, because at lower speed those collisions are also much less likely to occur at all.

If you could systematically reduce the speed on all urban/suburban streets to no more than 20 mph (actual driving speed, not posted limit), it would be a huge safety win for humans living in those places.

It would also make the environment much calmer, quieter, and less stressful.
Here's another one I was thinking about. It's an idea for a hierarchical Free Space Bitmap. I don't know if anything like this has appeared in a real file system or not.

At the lowest level, let's have one bit represent if a 4K chunk is free space or occupied. 64 bits at this level tells you the usage of 64 * 4096 bytes (256KB)

Then Level 2. Two arrays. One bit at this level represents 64 bits in the level 1 array. One array for All-Bits-Set in level 1, one array for Any-Bit-Set in level 1. 64 bits at Level 2 tells you usage of 64 * 64 * 4096 bytes (16MB).

Then Level 3. Two arrays. One bit at this level represents 64 bits in the level 2 array. One array for All-Bits-Set in level 2, one array for Any-Bit-Set in level 2. 64 bits at Level 3 tells you the usage of 1GB.

I'd imagine there would be ways to use the hierarchical tables to quickly find a hole of a particular size without checking only the lowest level.
Good lord the PRICE difference alone
Sure. Any idea how to do that?
> Extremely cheap experiments.

Well, their theory extended into more extreme regimes. Blame them for making theories about such small or fast things.

> Was it worth it in order to remove the 0.00001% chance that Einstein was wrong?

Even Einstein thought that GWs would be unobservable, they were basically a fringe theory, much like wormholes. The change across both astronomy and general relativity due to observing GWs is also quite vast. It could show us the currently unknown neutron star matter equation of state, which could have profound impacts on a quantum theory of gravity.

I don't think you really know what you are talking about frankly, both the LHC and projects like LIGO, VIRGO, KAGRA have had HUGE impacts on physics. I work on LIGO myself, specifically on new methods for reducing quantum noise, and that has huge impacts on high precision measurements. One example would be the incredible new breakthroughs in non-classical states of light, such as squeezed light. Yesterday in journal club we read a paper about how squeezed light could be used to greatly enhance the sensitivity of the tracking of biological particles. Also not only new practical techniques, but a huge amount of interesting new fundamental quantum measurement theory came about due to these detectors. The list goes on and on, I could fill many pages listing both the primary science and secondary technology (especially quantum technology) benefits that came from LIGO. It was absolutely 100% worth it

A surprise chicane, without even a sign, on a road with a history of speeding cars. What could possibly go wrong?

This also seems to be farm country. Converting productive fields to non-productive traffic calming structures would be about as popular as banning pickup trucks.
that is what multiple reproductions are for

indeed, the initial experiment is not immune to such concerns, and might itself have succeeded by making a mistake or failed because it lacked the technical capability

The counterintuitive thing to do is to make roads "feel" unsafe to make them safe.

A example of this (here done for laugh) is [0], where a single lane muddy curvy hillside road has a speed limit of 80 km/h (50 mph).

The point I would like to make here is that on a street like this is it impossible to joyride and even with low visibility intersections the risk of a T-bone or a fatal crash is minuscule.

This particular example is a strawman of the problem: there are many reasons why most roads cannot be like this, it is just an example of "If the drivers have to pay attention they will pay attention"

For routing you can also use a sparse radix tree, also known as a Patricia tree. This allows fast matching against a set prefixes (which is used for IP routing) without taking up a lot of space.
Used to love visiting two places on my yearly visits to Silicon Valley. One was the Computer Literacy bookstore and the other was Fry's computer store. Always spent money at both on each visit. Neither Detroit or Chicago had anything to compare to them.
Everyone needs shelter, sure. But just because Malibu is nice doesn't mean I can just show up there and expect a place to live while doing the most basic of jobs. You can extrapolate this to any town that doesn't fit the budget. You can get a studio in Merced, CA for $600 a month.

And we're not even talking about shelter. We're talking about owning a piece of the earth and having dozens of other humans build you a shelter, and then letting you sell it one day. Making other humans build you a home probably isn't going to ever be so cheap that everyone could just buy their own. That's why people live with family or friends or work to learn skills beyond minimum wage.
What I hoped for was a list of RAM requirements. Models are often presented as if it's irrelevant how many 80GB A100s you need. But in reality, trying out even inference often has a hard threshold based on the hardware you have at hand. And that hardware still is predominantly <= 24GB (3090 TI, A5000, A30).

Does anybody know of such a list? I.e. models with their respective minimum RAM requirements?
Thanks this website is very helpful!

And then we travell to some third world country to buy "forrest planted" certificates from some corrupt official, to return that imaginary crime number down to zero with imaginary good deeds.

And that kids is how you not only not solve a problem, but introduce a bureaucratic feeld good layer that actually accelerates the problems.

Easier solution would be to just compute industrial product logetivity, aka how long it lasts as a usefull entity and tax accordingly. That would change things up, to reward a car lasting 40 years.
The trained model is the hypothesis. We test the hypothesis by validating the model against unseen data.

I see this discussion ends where all crypto/Web3 proponents end it: discussion of specifics.

Crypto seems to be great when waving problems away, but no one seems to be able to give implementation details.
The term "Inflation" is used in two forms interchangeably by most people, and this leads to miscommunication. Inflation is used for:

(a) price inflation: increasing prices for individual goods.

(b) monetary inflation: an increase in the amount of money used.

Both types of inflation means you get less goods for the same amount of (in this instance) Dollars. Monetary inflation (b) is mostly created by central banks and commercial banks, who increase the amount of dollars via Quantitative Easing, or fractional reserve banking. Price inflation (a) is the effect of markets reacting to changes in supplies and macro trends.

Price inflation isn't even over all products, and products generally fall into three categories: deflationary goods, stable goods, and inflationary goods. Deflationary goods have traditionally been electronics like televisions. Innovation in these areas drives down prices for products hard. Stable goods are products like lumber, food, or oil. Inflationary goods are often luxury brand items like Gucci bags, or yachts.

What is noticeable now is a marked increase in price inflation for stable goods. The source of this inflation is usually one of the following:

1. Supply-side issues (Chinese harbours closed because of Corona outbreaks, the issue with meat as discussed in the article)

2. ESG goals driving up energy prices (which affect production costs and prices for fertiliser. A good example of this is Sri Lanka)

3. International sanctions against Russia (further increasing the cost for fertiliser and increasing the price of energy for the western European market).
I have to agree. Adding safe, non-automatic memory management to a language will increase its complexity considerably, and I don’t see it changing even with the below mentioned new languages/techniques. Even just fundamentally, manual memory management begets functions that know about the memory architecture of your program, solidifying a given architecture. Changing this latter will result in a recursive refactor, which even if safe, is problematic/complex.

Sure, it is a worthy tradeoff in certain, very niche cases (though other than writing other performant runtimes and realtime audio processing, I fail to see another area where a GC couldn’t fit - including even OSs), for which we need a language, but I really don’t get this recent hate for garbage collection, when it is truly one of the biggest productivity improvements for a PL, while simultaneously it being very performant (quite likely outperforming any naive manual take on more complex problems).
No salary range usually means salary dumping.

Where I work the management play this game, job postings without salary range and then they try the lower possible offer.
Finland is not one high trust society. Its two. They almost had a civil war back then when the sovjets nearly invaded and society split in two high trust societies (left - stalin collaborateurs) and right (finland patriots). There are still towns were the sides do not shop in the same super market.
You don't even that to go as high as 10,000. Imagine someone suddenly doing the job of 10 persons, that's entire teams being decimated. Go to a job board and imagine 9 of out 10 job postings not existing. How much harder it'll be to seek another job.
We’re told that you need to squat with a vertical spine and vertical shins. Even high school kids figure out that’s impossible to do.

I’m in full alignment with the article: squatting is just about balance in the end: how can you keep your center of gravity over mid foot as you bring your hips below (or near) your knees and back up again. You might find cues that help you find a good, repeatable position (break at the hips, stay tall, weight back, drop into your ankles, knees out, etc), but that’s personal to you. If you squat a lot, you’ll find the positions that knock you off balance, or bother your hips, or cause strain on your ankles, or whatever, and learn to avoid them with cues that help you find the groove where nothing hurts.
Yeah, infectious disease beats free assembly every time.
Also, the algorithms around using Reduced Order Binary Decision Diagrams (ROBDD) to represent sets efficiently. They are used in verification algorithms with very large state spaces, such as "Symbolic Model Checking: 10^20 states and beyond" by Burch, Clarke, and McMillan <http://www.cse.chalmers.se/edu/year/2012/course/TDA956/Paper...>

I want to write a content based pub/sub system. Where a subscriber says "I want messages where field X = A, y = B and z > C".

I've looked around and I've seen R+ Trees are potentially a solution but there's very little info on how they're actually created in code.

Does anyone know of any nice data structures to do this? Obviously the most basic way is just indexing each field and that works for simple equality but gets harder when you're trying to do other comparators like < and >.
Basically all tech reviewers, LTT included, are garbage because of this arrangement.

To have a day one review, you have to get a prerelease device. To get said device, you have to stick to mfg talking points. It's an awful circle of scummy companies and scummy people.

Really wish there was a reviewer who just buys shit with their own money AFTER release, and tells it like it is. Some may exist, but none of the household names have the integrity to do so.
I am an experienced ML Engineer of 10 years and have worked at several large flagship tech companies. I do not agree that fastai is not appropriate for real-life projects. If you know the fastai library well, you know its a layered api on top of pytorch, which allows you to customize things to your needs quite easily. For example, it is fairly straightforward to get any pytorch model out of a Learner object. Furthermore, lots of care has been taken to keep the apis very consistent with pytorch as well.

It's also the only library I know of that consistently bakes in best practices like super convergence techniques or making things like test time augmentation very seamless. Many libraries lag behind fastai 1-2 years in this regards, and frankly it can be frustrating to use other frameworks sometimes.

There is a slight learning curve, for example to learn the DataBlocks API or the callback system, but once you really understand what is happening you will understand how nice the API is and how well engineered it is.

Side note: Regarding being an experienced software engineer, I highly recommend digging into how the python language was extended for this project (fastcore) and the development workflow used (nbdev), which I think could be interesting for those software engineers you mention as well as heighten your understanding of the ecosystem of tools.
He wants to talk about black on black crime. As opposed to white on white crime which is not talked about as separate issue. Because, most murder by large number are among people who know each other - are friends, family, do business. And those groups tend to have same race.
I worked for a pharmaceutical company that tried to open a second factory producing more of the same thing that it was already successfully making and it never worked. They built the entire factory, it didn't work, they spent years and millions of dollars trying to debug it, it simply never worked out. They ended up just essentially running the US factory at three shifts to meet the increased demand. To this day I don't think anyone knows why the European production line never worked. Things can fail to reproduce without fraud.
A lot of people don't know about the related segment and interval trees. Both efficiently allow you to compute all time ranges that overlap a point. This can be generalized to higher dimensional spaces.

For example if you have a set of calendar invites with a start and stop time (say tens of millions of them) and you want to find all invites which span 12pm (that is start before 12 and end after 12) you want an interval tree.

I don’t really see how it meets that definition. It’s not a note or a contract, it’s just numbers and a global state, it represents nothing.

Inflation is when the ratio of <money available>/<goods available> grows.

This can happen by the numerator growing (your (a)) or the denominator shrinking (your (b)).
Thanks. What I like about w3m is 1) opening images via an external viewer if I want to, and 2) the UI, where everything is done on a command line at the bottom of the screen, vi-style. No input boxes like in Links. That aside, I remember thinking that Links did render some HTML elements better than w3m, though.

For contemporary w3m trickery, see http://w3m.rocks

EDIT: mynx looks interesting, I wasn't aware of it. Really close to my dream browsing experience: A browser that renders HTML as text, has only a few control keys (w3m has quite many, and it can cause confusion at times). Customizing would only be possible via config.h, including handles for viewing images, PDF files etc. I wonder why mynx lacks a "back" key, though.

My absolute favorite, Cuckoo hashing, has been mentioned already, but so far (239 comment in) nobody has mention this approach (called?) to store an array A[] of N-bit numbers, most of which are zero or small: use N set of numbers S[N], such that for each A[I] you store I in S[J] where J are the bit positions where A[I] have a set bit. In other words, S[J] are the indices of elements from A that has a set bit in position J.

The representation of S can be anything, and even dynamically adapting to the data. I’ve seen trees of bitmaps for example.
For the amount of effort put into customer tracking, big data, and using machine learning to crunch on the results, the advertising and marketing industry should have this nailed by now. If they don't, maybe it's impossible.
Ok, by that measure I guess over 90% of projects would fail. Which would probably be unfair in most cases, because unlike this project, where the scope as defined by the client was 100% clear from the start, most clients when starting out with a project can't really say exactly what they want, so the scope creep is not only driven by the agency, but also (sometimes mostly) by the client.
Its relatable; I belong to the same part of the world.
XFS has a long and solid track record, but without the workload-dependent regressions which can be encountered in a copy-on-write filesystem. Decent hard drives have had internal checksums for ages. If the drive is even halfway functioning, it will catch the bad blocks--making that particular ZFS feature largely redundant, and databases that matter are going to be on a RAID anyway, which has its own additional layer of parity.

ZFS is fantastic for some applications, not so much for others.
Of course. But these points aren't aimed at the EU (they don't have a leg to stand on, at most they can say they need more time but they can't really find good arguments against the new law). The way I see it, Apple has 3 options:

1) Appeal to infinity, using all resources they can.

2) Comply but make things so difficult for the user that they effectively retain the control over the device as before. (Anybody remembers browserchoice.eu?)

3) Convince the US government the law goes too far and they should intervene. Given the war in Ukraine, it would be extremely easy to convince the countries bordering with Russia, Belarus and Ukraine they should support the USA in this case.
All of this is great, you just need to adjust your threshold for automation so that it results in net savings when it comes to time.
People don't seem to grasp that 9% inflation is extremely high across an economy as large as the US. The 70s had 15% inflation, everyone with their rage boner demanding 50% inflation in the CPI wants ridiculous reports of hyperinflation.

Finger trees. They work on an arbitrary monoid and maintain a list of items.
You can insert and remove items in logarithmic time, as well as ask for the sum of items in a given range, also in logarithmic time.

This is useful for example when you want to convert between offsets and line/column numbers efficiently, while you also want to efficiently update/insert/replace lines.
