Is it just me or does the data aspect of the site feel horribly designed? E.g, the main graph is hard to read since most of the data points are in the $0.10/part range but the graph's y-axis is overwhelmed by the right side with it's $3.11/part train set. And if I click on that, https://brickinsights.com/sets/categories/26 shows 4 data points and it's overwhelmed by a single outlier from 1991. And the time-sequence chart near the bottom uses a line graph rather than a scatterplot which overwhelms the useful data.

A better graph would be a time-sequence scatterplot of price/part on a log scale like https://www.reddit.com/r/dataisbeautiful/comments/5oanki/leg...

Almost every Lego set I've ever owned (going back 30+ years to when I used to get Lego) and now my son's Lego recently have all had at least one leftover piece.
That's what I mean, when Google became generally available they had none of that on their site.

For quite a while at least before they joined the crowd.
See also the Lean Game Server at https://adam.math.hhu.de/ , and in particular the "Natural Number Game" (for Lean 4!), which has done the rounds on HN a few times.

Does anyone know of a Lean book that builds up the basics from absolutely nothing, not even the Lean standard library? I'm curious about the foundations that lie just above the language.
This is a personal project aiming to replicate analog coupling dynamics with asynchronous digital circuits FPGAs, not a claim that we can solve NP complete problems with a fundamental speedup.

Also, these sorts of Ising architectures get their speed-up are based on oscillator interaction, not parallelism. It's relevant to this article because it leverages oscillators on FPGAs in a nifty way :)

One solution that I use and like because it is reliable, is to change the BIOS to "Power On" after a power failure and use a smart plug to turn on the computer.

So turning the smart plug on my phone on would start the computer. I use it for my backup server with a JBOD that is only turned on when I need it. You can also schedule on/off time on the app. And if you want to programmatically turn it on/off you can setup Home Assistant with the plug.
Considering that I would pay double this to avoid doing a captcha, I conclude that 1) captchas are irretrievably broken, 2) there is a profitable arbitrage opportunity here.
Unfortunately not. I can understand if that's a dealbreaker for you.

There are a few reasons we're not using iCloud:
1. We eventually intend to support other platforms, like Windows and the web.
2. Though they're admittedly rare, we've heard some iCloud horror stories. @DanielDe (OP) lost some files using iCloud Drive, so it's hard for us to trust it.
3. We wanted much tighter control over syncing to provide the particular experience we were aiming for. Things like live cursors for shared lists, and the way our offline experience works, are tightly tied into our sync engine.

Hamas knew the response would be disproportionate, it banked on it.
I think it's the first war where one party is trying to maximize losses in its own populace (using human shields or just lying and using basic propaganda/Pallywood style videos). The whole point is to try to isolate Israel, make it pariah state.
And it's working at least from an international politics viewpoint.
The thing is nobody in Israel really cares about it now. So the slow process of turning Gaza into a pile of rubble is progressing regardless.

Now the important point is when it's all over, Netanyahu is kicked out and the new Israeli government will work hard to prevent anything from growing back in Gaza. If the coward Netanyahu stays, everything will come back to the same old "Concept" and Hamas will be back (it's already happening, the port they are building). Netanyahu needs Hamas and Hamas needs Netanyahu.
I live in Germany, and am moving to a place ~50km from my workplace. It's a small town with about 15k inhabitants. It's an affordable and nice place, but I'm only really doing because there's a direct regional train to the main city. In fact, I can commute faster than some people living _in_ the city.

But here's the thing: this train I'm talking about _is not_ an ICE, it's a _regional_ train, but it makes only one stop, and cruises at 160km/h. And being a regional train, I can ride on the Deutschlandticket, which costs 49 euros a month. Even if they raise the price on that ticket (likely), it will still be worth.

Good regional train services is the key to this problem. Provide nice services into the cities, allow those towns to densify around their station, and that will relieve the pressure.
I can't believe it's been 8 years.
While I absolutely agree with PG here on identifying a missing link and solving it with technology as your own project is a good way to own a startup, I also feel most of his examples are reminiscent of survivorship bias.

For every one of these giant trillion dollar companies, there are also thousands of companies that couldn't make it. Also, just by the distribution of it all, not every company can be a Google. Not trying to be pessimistic here; everyone should be able to try solving some problem as a project and have fun meanwhile. However, expecting a Google out of it could be a bit too demanding.

Sunsetting OpenBB Terminal: Why, How, and What Now?
Dry Clutch DCT technology is nearly equivalent efficiency to a manual transmission. Its the same dry-clutch to connect the engine to the wheels after all, though there's additional weight required as Gear1/3/5/7 are on Clutch#1 and Gear2/4/6/8 are on Clutch#2.

ZF-8 apparently removed a lot of the "slushbox" / wet-clutch problems with efficiency. Its apparently the best / peak automatic transmission technology with exceptionally good reviews and specifications, though the main problem seems to be downshifts. But upshifts (1->2->3->4...) are basically solved with ZF-8 and operate at high efficiency.

CVTs are manual-transmission/clutch-like levels of efficiency, though there's so much diversity in CVT implementations I feel like its hard to discuss.

Hybrid Vehicles are either directly-connected / 1-gear systems (ex: Honda: ICE Engine gets a gear and EV engine gets a 2nd gear, no transmission otherwise required), or the Toyota Power-split device (aka: Prius) that has exceptionally good efficiency as you're probably aware.

----------

Manual Transmission's main benefit is economy. Its just a bit of hydraulics controlling a drum-brake like system (aka: the Clutch) with a human controlling the gears, so no need for any complex logic.

I think economy cars / low-cost cars need to go back to manual transmissions. But maybe USA is just too rich and that the $20,000+ price point is high enough to just default to automatic transmissions.

There's a lot of "machine empathy" in manual transmissions, they're exceptionally simple, cheap, and reliable (when used properly).
From the description, one small part of the code:

--64[T=1[O=32[L=(X=*Y&7)&1,o=X/2&1,l]=0,t=(c=y)&7,a=c/8&7,Y]>>6,g=~-T?y:(n)y,d=BX=y,l]

The difference between bf and c sometimes is small
Ehhh, that's a poor take. The indirect benefits of fundamental research like particle physics are massive.

We all know about how the web — which turned out to have a few commercial applications — was invented by Tim Berners-Lee at CERN in order to facilitate better collaboration and data sharing among researchers.

There's the advances in high-performance computing and data processing, medical imaging innovations like PET scans, fundamental tech for touchscreens, and so on.

And don't get me started on the motivational and inspirational value of science and how it encourages people to pursue engineering and other technical endeavors. Hard to measure, sure, but it's damn important. There's a reason the moon landing was the most watched event in the history of television.

It's difficult to overstate these indirect impacts.

The Fujitsu device is a synchronous digital architecture. I'm using asynchronous oscillators, more like Lo et. al. (https://www.nature.com/articles/s41593-024-01607-5)

The timing is a little muddled here - Scott Hassan (who, interestingly enough, wrote most of the original code for Google) founded eGroups with Carl Page in 1997, after working on BackRub/Google. The two should be viewed as parallel projects - Google actually started first, but eGroups raised money first. It’s true that Larry got valuable experience through having his brother raise capital first, but much of that also came from having supportive angels like (Sun founder) Andy Bechtolsteim, (Stanford professor and Granite Systems founder) David Cheriton, (Junglee and Netscape exec) Ram Shriram, and (Amazon founder) Jeff Bezos.

How hard are you pressing the clutch that it gives you knee pain?

I did my first 10 years of driving in a manual and when you get a hang of the gearbox you barely need the clutch at all. Just a light tap, barely disengage anything.

Nowadays the sequential dogbox in my motorcycle is my fav. Similar to what rally cars use. You only need the clutch when stopping, otherwise you can just jam between gears with a light flick of the throttle to relieve tension. No electronics.

Wish nonracing cars came with that option. I think some 90’s supercars have it.
Call me crazy, but I don't think the goal of AI should be to give the rock with electricity in it "a valuable experience".
Mostly coincidentally--although there were one or two overlapping participants--Cognitive Science is usually dated to an MIT conference a few months later. (Although I don't think it was called that yet.)
Wait, does it also simulate the feel of the torque curve?
I've tried it before. I didn't find it meaningfully better than a moleskine with grid paper (in some ways worse) or sticky notes around my monitor. Again, paper for task management doesn't work for me
I don't know what it's like in the states, but if you do that here in the UK then some idiot will jump into the gap in a bid to try and get a couple of car-lengths ahead and then you're forced to brake anyway.
Hm thanks for reminding me that I need to change the fluid in my DSG.

It's annoying that the VW manual suggests comically long service intervals for this stuff to make it look like the running costs are lower than they are. I want to just keep the car until it has 300k+ miles. But it's all about shifting those units initially.
Yes! Super important feature that I'm realizing we never mention on the website, I'll have to add it. Thanks for bringing that to our attention :)

I've always wondered if it would be able to build a car transmission with a clutch similar to a motorcycle. Those are very easy to replace.
1. Self guided recurrent loops. Rnns are difficult to train correctly, which is why transformer architecture took over, but for reasoning there needs to be some sort of recurrent loop that is self determined by the model to iterate on the correct answer.

Can you explain this some more?
The E=mc² article is performative art. The origin of it, if I had to guess, was someone saying "moral relativism is evil" then, "all forms of relativism are evil", then "general and special relativity are evil". I can't really tell if it's an honest view or not, but the related articles also seem to illustrate how hard it is for "big tent conservatism" to form a cohesive world. If Einstein is right, then the speed of light was a constant and matter warps space as we observe with telescopes. If things are billions of light years away, then the world can't be 6000 years old. If the world isn't 6000 years old, the bible isn't literally true in all respects.

There's also the question of incident response, if a human driver "malfunctions" you take them out of service and the rest of the world keeps going, but if a self-driving model malfunctions there are potentially millions of vehicles running the same software ready to make exactly the same mistake until the issue is isolated and fixed. Should we ground the entire fleet of vehicles running that software until the issue is resolved and software re-certified, if the software is demonstrably dangerous? How much would that cost?

VW/Audi DCT has manual mode that allows shift up/down and stays set on a gear. The only difference is it won’t comply if you aggressively downshift or will eventually shift up if you rev too much.
since when do you have CDC out of the box with PG though?

Accident-driven development.
don't forget the part where EVs are making transmissions themselves obsolete. there are still underlying gears, but there's just not a transmission in the same way.
I don’t think people are so simple - that Aldous Huxley joked about wanting more sex doesn’t convince me that’s truly the driving force of his entire life. And, just practically speaking, a smart scientist man could live a sex-filled emotionless life at that time, and still today… you don’t need to be a nihilist to go on Ashley Madison or seek a Sugar Baby.

More substantively, it seems like you’re endorsing a view that Wikipedia sums up as anti scientific and biased. I hate to dismiss someone so blithely but it is fairly strongly worded. To quote the spiciest parts:

Freeman's book was controversial in its turn and was met with considerable backlash and harsh criticism from the anthropology community, but it was received enthusiastically by communities of scientists who believed that sexual mores were more or less universal across cultures. Later in 1983, a special session of Mead's supporters in the American Anthropological Association (to which Freeman was not invited) declared it to be "poorly written, unscientific, irresponsible and misleading." Some anthropologists who studied Samoan culture argued in favor of Freeman's findings and contradicted those of Mead, but others argued that Freeman's work did not invalidate Mead's work because Samoan culture had been changed by the integration of Christianity in the decades between Mead's and Freeman's fieldwork periods.

Eleanor Leacock traveled to Samoa in 1985 and undertook research among the youth living in urban areas. The research results indicate that the assertions of Derek Freeman were seriously flawed.

At the least, I think we should all agree that no one was out to “prove the way humanity should be”, just explore non-western ways of life. And I believe the consensus among gender theorists and anthropologists is that western sexuality is arbitrary in many ways. That’s not a condemnation of every single part of it, especially dishonest adultery as you seem focused on, but it’s certainly a reason to investigate non-western society’s IMO.

> For what it's worth, a response time of 100ms is perceived as instantaneous

That's not true. From the source you cited:

> Increasing latency above 13 ms has an increasingly negative impact on human performance for a given task. While imperceptible at first, added latency continues to degrade a human’s processing ability until approaching 75 to 100 ms. Here we become very conscious that input has become too slow

The 100ms figure was in regard to conversational interactions with a computer.

It's the best place I know of for math gossip.
Concentric-shaft wet DCTs aren't bad - for example, replacing the clutch pack on a VW DQ250 is very similar to replacing the torque converter on an automatic. You have to drain it but it's not particularly involved. There's basically a cover on the bell housing behind the flywheel, drain the fluid, remove the snap ring, and you're looking at the clutch pack. Lift it off and lift a new one back on.

Rebuilding the clutch packs themselves is a tedious and obnoxious process, because they're a giant stack of friction material that needs to be shimmed into tolerance, but you often just buy the clutch pack as a whole assembly.

I'd massively prefer a wet clutch even for long term serviceability - a few hundred dollars or less every year or two for fresh fluid and you've got a long service life before an expensive removal.
Do you know if there's a better link or obituary than this rather barebones wikipedia page?
I hate to burst your bubble, but when you do the dynamic systems math, they are sadly equivalent. You are working in the continuous time domain while the synchronous devices are working in the discrete time domain.
I can't tell if this is sarcastic or not.

Surely we should encourage young scientists to "dream big", as long as we also teach them to actually "do science" effectively right?

Maybe it's the vagueness of what "dream" means here. Imagination, creativity, and the like can be valuable insofar as they steer us to look in new useful directions and ask new useful questions. As long as the "looking" and "asking" are done with an honest aim toward finding the truth and an understanding of the tools scientists have developed to do that effectively I don't see the problem.

I don't see the takeaway message from this article being "this scientist's dreams were too lofty", but something more like "this scientist ignored good scientific practice in pursuit of his lofty dreams".
I made a script last year that scraped LEGO pricing data from their website. Besides finding out that the Bugatti Bolide Technic set is a pretty good deal as a parts bag, I found that there's only a weak correlation between set size and PPP. The Dots sets throw a wrench in things, of course, and large Technic sets often have expensive electronic and pneumatic parts that must be considered.

My conclusion was that PPP is useful as a bargain-hunting tool, but not as a model for broad price analysis.

Here's that for anyone interested:

I bet it's more likely that a given Lego set that is missing pieces was produced, packaged, shipped, and sold, nearby other piece-missing sets.

In other words, I would not expect the distribution of Lego sets that are missing pieces to be evenly or randomly distributed.
having collected through the 90's, I can attest that there are a lot less specialty parts now, but in recent sets that number appears to be growing again. almost every fairly large set I've purchased in the last 2 years have had 10-12 new-to-me parts in it, and the other sets continue to include those same parts as well.

mostly, they've been pieces to make some change for SNOT, but there seem to be so many of them now that it feels like we're going back to that 90's mentality.

some of those sets:

* batman shadow box (with my first ever missing piece!)
* dune ornithopter (great build)
* loop rollercoaster (not counting those loop tracks)
* orient express (my least favorite build in the last few years)

> The solution to these problems came from Khuri-Yakub’s lab at Stanford University. In experiments in the early 2000s, the researchers found that increasing the voltage on CMUT-like structures caused the electrostatic forces to overcome the restoring forces of the membrane. As a result, the center of the membrane collapses onto the substrate.
