I’m not aware of studies involving radiocarbon dating of paved roads, so I can’t say conclusively, but I believe the leading hypothesis is that they didn’t exist 50,000 years ago.

I am aware of using phase change of water for various cooling purposes. Finding references again on them isn't difficult if you know what you're looking for.

Many years ago there was a green building series on KQED that featured such approaches.

Shifting when you are using energy is part of conservation.

As to how it works... it's a cubic rather than planar ice skating rink. You freeze a block of water at night, and then during the day, slowly melt it as you transfer waste heat from the building into it (rather than rejecting the waste heat with a compressor during peak energy use hours).

Distant area code SIMs do wonders.

I was still living in Vancouver, Canada when I learned maybe six or so years ago AT&T has removed all roaming restrictions in North America. So a few of us banded together, one of us crossed over to New York picked up a group subscription of sorts and we had very cheap subscriptions. Only the last 1-2 years did Canadian providers caught up, somewhat.

But the real advantage was if anyone called from a "local" number, local to my SIM at least, I immediately knew it was spam. I do not know anyone in Buffalo, I do not do business in Buffalo, there's no authority which has anything to do with me there, nothing. It's spam.

Patlabor is criminally underrated, in particular Patlabor II by Oshii. Often neglected given how popular his other stuff like GitS is but probably one of the best animated films when it comes to post WWII Japan's military/political questions.

All 2FA really boils down to is a "otpauth://totp" URL that clients use to generate time based tokens. Once you have those exported somewhere, you can move to any TOTP app you want (desktop or mobile)

Haha, I see you manically rage posting in this topic. I empathise, it's fucking shit when "smart" people foist something unwanted on you because they think it's better for you. FWIW, I'm feeling pretty liberated to have moved my OTP codes out of authy and into multiple locations - my data, as much as I'd prefer not to use it, is now under my control.

You can get the old desktop version from chocolatey/choco - https://community.chocolatey.org/packages/authy-desktop/

If anyone wants to try this themselves, this is the recipe that worked for me;

- Enable multi device for authy on my phone

- Install the 3.0 desktop authy client from chocolatey

- Get logged in and set up on the desktop client so that you can see the current OTP codes (not the lock symbol)

- Uninstall the 3.0.0 desktop authy client

- Install the 2.2.3 desktop authy client from chocolatey (https://community.chocolatey.org/packages/authy-desktop/2.2.... or choco install authy-desktop --version=2.2.3)

- DISCONNECT FROM THE INTERNET AFTER OPENING 2.2.3 AND BEFORE IT POPS THE UPDATE DIALOG

- The update dialog will block the program and you can't use the chrome remote debugger in the later steps

- Start from step 2 of https://gist.github.com/gboudreau/94bb0c11a6209c82418d01a59d...

This reminded me so much of math tutoring, and so little of technology.

The tutor helps immerse the student; the tutor creates a rapid feedback loop for the student to test out ideas; the tutor scaffolds problems and adjusts to the student's pace and failures; the tutor ought to motivate the student.

I worry that these thought-pieces are too dreamy, and that there's unrealistic expectations for tech to solve teaching. Hopefully those in this space are grounded by real teaching experience.

Ultimately, I've found that the best learning happens with highly motivated students and/or with thoughtfully designed learning content. On well-designed content: I'm reminded of the recent HN post about map coloring, which was scaffolded into simple steps with basic interaction, and another post about Chile, which flowed smoothly with digestible writing and lots of images. The tech was largely irrelevant to those posts.

My annoyance is that _anyone_ would write a book on a technical subject who knows absolutely nothing about the subject. LLMs aren't a philosophical concept; they're a software mechanism with myriad constraints and design limitations built in. Understanding their future demands a deep understanding of those mechanisms. So why on earth would an academic who knows zero about engineering, software, or AI techniques have the temerity to write a book suggesting he can see farther into the evolution of LLMs than, say, a carpenter or bricklayer? At least those skills know something about physical mechanisms and engineering constraints. But not Bostrom.

The continued interest in a book of bold uninformed argumentation that's so obviously insubstantial just goes to show how bad humans are at telling the difference between useful knowledge and wild speculation. It's almost as silly as caring whether the prognostications of Rod Brooks (or worse still, Ray Kurzweil) come true. As if guessing right actually meant something...
> Professor Woan used a technique called Bayesian analysis, which uses probability to quantify uncertainty based on incomplete data, to calculate the likely number of holes in the mechanism using the positions of the surviving holes and the placement of the ring’s surviving six fragments. His results showed strong evidence that the mechanism’s calendar ring contained either 354 or 355 holes.

> At the same time, one of Professor Woan’s colleagues at the University’s Institute for Gravitational Research, Dr Joseph Bayley, had also heard about the problem. He adapted techniques used by their research group to analyse the signals picked up by the LIGO gravitational wave detectors, which measure the tiny ripples in spacetime, caused by massive astronomical events like the collision of black holes, as they pass through the Earth, to scrutinise the calendar ring.

The title was very clickbait
Yeah, the more I read the post the more confused I am actually. At first glance to me this seemed like a non-paradox. So I kept wondering if I'm missing something, but based on everyone's responses, maybe I'm not?
I was curious, because I was always told Hawthorns weren't poisonous, and I can't find anything more about this. The only source seems to be the book itself, I couldn't find the study, and I can't find any other sources that say Hawthorn or its thorns are poisonous.

Either way, it's probably a bad idea to get stabbed in the eye by their thorns.
The 'smart' animal club keeps getting bigger
> A spokesperson for the German Federal Office for Economic Affairs and Export Control confirmed that quantum computer export controls would be the result of negotiations under the Wassenaar Arrangement

So confirmed to be not mysterious and instead enacted through a defined a known process? The only mysterious part is countries not sharing the analysis for the specific qubits but that doesn’t sound too unreasonable.
I like The Guardian for sports, particularly football.
This isn't that strange or mysterious.

The main reason that nations and multinational corporations have been investing in post-quantum cryptography is the looming threat of Store Now Decrypt Later attacks.

Given that, it makes logical sense they would also want to control exports of the tech that would undo their other investments. But they don't want to stymy industry or academia, so they set a threshold that prevents the unlimited distribution of practical tech that may be cryptography-relevant.

This is even less surprising when you consider the biggest investor into quantum computers is China, and probably not for philanthropic reasons.

One curiosity I have: Do they mean 34 stable cubits, or would 34 unstable cubits count?

Some more discussion last week: https://news.ycombinator.com/item?id=40817306
“In Adreno tradition, Adreno X1’s first level cache is a dedicated texture cache. Compute accesses bypass the L1 and go to the next level in the cache hierarchy. It’s quite different from current AMD, Nvidia, and Intel GPU architectures, which have a general purpose first level cache with significant capacity. On prior Adreno generations, the GPU-wide L2 cache would have to absorb all compute accesses. Adreno X1 takes some pressure off the L2 by adding 128 KB cluster caches.”

People have been tinkering with L1 cache conditionality since the L1i and L1d split in 1976 but the Qualcomm people are going hard on this and the jury seems out how it’s going to play.

The line between the L1 and the register file has been getting blurrier every year for over a decade and I increasingly have a heuristic around paying the most attention to L2 behavior until the profiles are in but I’m admittedly engaging in alchemy.

Can any serious chip people as opposed to an enthusiastic novice like myself weigh in on how the thinking is shaping up WRT this?

> people like owning multiple devices that fit the mood

Agree this is a big factor, but with peripherals to extend your smartphone into a laptop you do still have to own multiple “devices” (discrete units of physical hardware). If you’re already gonna have to lug around a dongle/adapter and one or more pieces of hardware (mouse, keyboard, screen) to get the laptop experience, you might as well just lug around an entire laptop.

Also, “cloud” software (not just things like Google docs, but the widespread use of web applications allowing you to log in to some app from anywhere) has solved a lot of the biggest problems in this space. You can easily access all the important things on your phone from a laptop, unless you go out of your way to not upload something somewhere. So being able to convert a smartphone into a laptop is mostly about saving money on hardware (which may not be that much. Do you pay $200 for peripherals to get an underpowered laptop powered by a phone, or a mid-like laptop?) or addressing a very niche UX need.
They aren't gunning for Chromebook deployments...these are currently in business laptop models and AMD may have already beaten them in all fronts on some of these per dollar other than ultralight and video playback duration. Lenovo has a A model that can do 16 hours and light gaming. more importantly it runs x86 apps full speed.

I agree these likely will take over the sub $1000 market if given the chance but they are shooting at $1500-2000
Yes, I understood - but this has nothing to do with encryption. Data that is encrypted is save. Any data that is not encrypted (or was not encrypted) would offer an attack surface. Since I use ZFS for all my data, all my data is encrypted from Minute 1 of a new hard drive.

Roku update turns on hated motion-smoothing feature, with no off switch
Thanks. Indeed, it doesn't directly answer my question. For one, the author seems to be failing the "Chesterton's fence" test here: it doesn't even try to answer what langchain is supposed to be good at, but ends up being bad. It just plainly says it's bad, that's all.

And, as stated, I also don't know the answer to that question, so this is kinda one of the primary concerns here. I mean, one possible answer seems pretty obvious to me: it would be better to keep your app vendor-agnostic (to be able to switch from OpenAI to Anthropic with 1 ENV var) if at all possible. Neither of articles and doc-pages I've read in the past few hours tries to answer to what extent this is possible and why, and if it even is supposed to be a real selling-point of langchain. TBH, I still have no idea what the main selling point even is.
Thank you - added to my wishlist

Study measuring toxic metals in tampons shows arsenic, lead, other contaminants
> The metal concentrations varied by where the tampons were purchased (US vs. EU/UK), organic vs. non-organic, and store- vs. name-brand. However, they found that metals were present in all types of tampons; no category had consistently lower concentrations of all or most metals. Lead concentrations were higher in non-organic tampons but arsenic was higher in organic tampons.
>
> Metals could make their way into tampons a number of ways: The cotton material could have absorbed the metals from water, air, soil, through a nearby contaminant (for example, if a cotton field was near a lead smelter), or some might be added intentionally during manufacturing as part of a pigment, whitener, antibacterial agent, or some other process in the factory producing the products.
Forgive me, I've been hearing that since 2010. I've been through at least a couple cycles of "but they are this time, seriously!" myself personally -- this most recent cycle was the first one the Apple inteligentsia widely agreed it wasn't worth even talking about.

Kafka versus Nabokov
I grew up in San Diego and at the time being involved with technology meant living in Qualcomm’s shadow in one way or another.

So I tend to agree that being the reference mobile SoC vendor outside of Cupertino is pretty on brand for their absolute top priority. At Qualcomm if it doesn’t make dollars it doesn’t make sense as we used to say.

And good for them! After a brief flirtation with the idea of becoming a pure play CDMA patent troll they seem to have gotten back to their roots and started doing engineering again. It’s a cool company.

I moved from British Columbia (250 area code) to the Montreal suburbs (450 area code). The one digit difference was a huge issue: the number of times businesses and government agencies would helpfully "correct" my phone number when I gave it to them or when they tried to call it meant I missed a substantial number of important phone calls. I get it, my French isn't the greatest and I have a thick Anglo accent, but "deux cinq zéro" sounds very different from "quatre cinq zéro." Eventually I just gave up and got a local number (I ported my old one to VOIP.ms and forwarded it so I wouldn't miss calls).

I think this is just an example of the fact that any tool can be misused or used poorly. I used scrum at my last employer, and it worked quite well. But we didn't use it stupidly; it was just a tool to keep track of what we were working on, and plan what we were going to work on next, that's all.

Sure, we had some discussions about story points, but they were quick. When we had to assign story points to a task, we'd all use story point playing cards (they have the typical Fibonacci sequence story points printed on them: 1, 2, 3, 5, 8, 13, 20) and turn them over at the same time to basically vote on the points. If there were any large disagreements (one person voting 1 while everyone else votes 8 for instance), we'd stop and discuss why that person thought it would be so much more or less effort. Usually, 30 seconds of discussion would clear up the disagreement and we'd move on to the next task. The whole meeting would last less than 1 hour, and was held every 2 weeks. And I think it had a secondary benefit: it got us all in the room together to just talk to each other as team, instead of just sitting in front of our computers and not talking to anyone, which was our usual activity. Social interaction is good for people.

I can relate so much! Went to Uffizi once, I wondered why so many people were lining up to get in because I had zero clue about art at the time, after deciding to actually take a look in the museum with audio guide, I spent almost 4 hours in Uffizi though I didn't have many clues about lots of them, I was just trying to "feel" the pieces, years later, I finally started to read books about art and suddenly I had this amazing realization of "wow isn't that art that I've seen before?" then it all makes sense now, it's one of the best feeling ever, now I usually just go checkout museums, venues or whatever it is because I know even though I cannot appreciate the art at the moment, some day in the future I'll be glad that I take the chance to look at it.
Exactly this. When I used it, that's exactly how it was, and honestly it was great compared to the utterly chaotic and disorganized method of organizing work I've seen in other workplaces.

It seems like all the people who absolutely hate it worked in dysfunctional places that completely misused the tool, or treated it like some kind of religion.

>There are several ways in which it's bad. Forcing all the work to fit into sprints, for instance.

That's misusing it. The sprints are just forcing regular meetings to assess progress and make changes if necessary. There's no reason to absolutely force everything to get done in 2 weeks. If something doesn't get finished in a sprint, discuss what happened in the biweekly meeting and if any changes need to be made, and then move it to the next sprint.
Not the parent, but I write recovery codes down and store in a safe at my home.

The difference compared to a password is that these recovery codes are single use, used only in exceptional cases and physically airgapped. On the other hand my password is multi use, is used daily by me and in the event of a breach will be exposed to the attacker.

I will know if someone steals my recovery codes. I'll have no idea if someone gains knowledge of my password though.
