The first discussion we should be having, is whether guardrails make sense at all. When I was young and first fiddling with electronics, a friend and I put together a voice synthesizer. Of course we had it say "bad" things.

Is it really so different with LLMs?

You can use your word processor to write all sorts of evil stuff. Would we want "guardrails" to prevent that? Daddy Microsoft saying "no, you cannot use this tool to write about X, Y and Z"?

This sounds to me like a really bad idea.
> IGA has a lot of potential to solve many of the pain points of FEM.

Isn't IGA's shtick just replacing classical shape functions with the splines used to specify the geometry?

If I recall correctly convergence rates are exactly the same, but the whole approach fails to realize that, other than boundaries, geometry and the fields of quantities of interest do not have the same spatial distributions.

IGA has been around for ages, and never materialized beyond the "let's reuse the CAD functions" trick, which ends up making the problem more complex without any tangible return when compared with plain old P-refinent. What is left in terms of potential?

> Tom Hughes, who is mentioned several times, is now the de facto leader of the IGA research community.

I recall the name Tom Hughes. I have his FEM book and he's been for years (decades) the only one pushing the concept. The reason being that the whole computational mechanics community looked at it,found it interesting, but ultimately wasn't worth the trouble. There are far more interesting and promising ideas in FEM than using splines to build elements.
As an autistic worker, I find it impossible to lie... could this help in a discrimination case?
How is its offline performance?
The problem is that it's doing both when it's only supposed to do one.
More than downloading a bunch of information, I would also think about hoarding computers that might last a long time if taken care of... along with a durable power source that doesn't require fossil fuels. (eg: This potentially includes gasification based generators)

For the internet to "go down for an indefinite period" there would need to be some pretty big changes to our current world. The reason it "goes down" also matters a lot.

1) Political reasons (eg: whomever is in power wants to control information flow)

This will likely mean that certain kinds of information can still flow because we don't want to crash the entire economy.

In this case, I would want all of the information I could get my hands on about known history. This includes previous regimes and how they ultimately played out.

2) Geo-political (some other country bans your access to their resources)

This is a harder case to enforce without complete isolation ... but theoretically possible.

In this case, technical howtos are still useful as you can probably still get modern supplies. Depending on what my country produces, I would probably want to get all information about those processes as I could. Also, if my country doesn't produce a lot of food, information on what can be grown locally would be helpful... along with ways to protect it from nature.

3) Global catastrophe (plague/virus/nuclear winter/etc...)

Maybe enough of the internet is just "lost" and the technical means to resurrect it has also disappeared.

At this point, you need to think about being completely self-sufficient. ie: Grow your own food, make your own tools, protect yourself from animals and people. It would be helpful to have some tools at the start for this. Maybe even just basic gardening tools and a greenhouse ... and whatever form of protection makes the most sense to you. Find some land that can sustain you; Leftover city supplies will likely disappear very fast.

4) All of the above, simultaneously.

It's time to just get a Bible and start praying. Maybe a bunker, too. Survival will likely be a lot of luck and a lot of cunning.
I mean, if you're willing to spend that much, and it'll be very expensive, then sure. It's just technophobia - machines are going to be more accurate than a human (who also can make a mistake!).
If sugar is added, it’s in the ingredients list in the EU. They are sorted by decreasing amount, hence while you won’t be able to tell exactly how much was added, you can narrow it down. But sometimes they add different sugar types and it becomes really difficult to estimate the quantity of added sugar.

Hence I would say it’s easy to know if sugar is added if you know the names it goes by. But it’s difficult to know how much.
It's not patenting Morse code. It's patenting adding the capability to a smartphone using a rocker switch.

Besides, I'm pretty sure the patent has expired.

My motivation on this was simply that I am an inventor, and what's an inventor without a patent here and there? The stuff I invented for D has not been patented.
>> as the "curse of dimensionality," where as dimensionality increases, the distance between points tends to become more uniform and large

Since embeddings are the middle layer of an ANN, doesn't this suggest that there are too many dimensions used during training. I would think a training goal would be to have relatively uniform coverage of the space
Author here. I now know some places in Melbourne that have a good success rate on projects. Some of them are so small as to be invisible and rarely hire. One uses two specific independent recruiters or internal referrals. As far as I know, they are extremely profitable because the competition is a joke.

For many organizations, the success rate is indeed 0%. A Group of Eight university (our top 8 universities nationwide), for example, sent me a job description a few months ago where they misspelled the word engineer, and left change tracking on in the Word document. This allowed me to walk through the profiles of the people running their data projects, and it was super obvious that many of the people involved aren't going to do a good job. They could have saved millions by having a random HN person eyeball the CVs of their chosen leadership team.
“Cunt” is not a particularly offensive word though. I think its a bit more taboo than bitch now, but I think its very common to use cunt/bitch/whore around women to signal a friendly/relaxed attitude.

I'm not sure why WebGPU is a step too far but WebGL isn't? Every other API for using a GPU went the same direction; why should HTML be stuck with a JS projection of OpenGL ES while native developers get Vulkan? The security properties of both are very similar, Vulkan/Metal/DX12 just lets you skip varying levels of compatibility nonsense inherent in old graphics APIs.

This is nice. Any way to also make it an Erlang complient node so it can be called from a erlang cluster?
It's a nice piece of machinery. Looks like they finally went all-electric and got rid of the hydraulics. The new model is much less bulky.

The task it is doing is undemanding. It's just moving things from one set of large slots to another. No need for precision placement, unstructured bin-picking, or object separation. If it could pick up engine covers from the messy pile seen atop one of the racks and slot them into the storage unit, that would be more impressive. It's cool to see this done with a humanoid, but off the shelf industrial robots could do that job. This is the same place where Rethink Robotics got stuck. They could do simple object movements in mostly-structured situations, but so can lots of other simpler approaches.

Amazon, despite substantial efforts, still doesn't have full robot picking. About two years ago, Amazon announced their "Sparrow" picking robot. But that seems to be experimental. It's not seen in videos of Amazon warehouses in 2024. Amazon is using the Agility humanoid, but only experimentally.[1]

This is how Amazon currently does picking.[2] Racks of product come to the picker on robotic platforms. The picking system projects a light square on the space in the rack from which the picker should take the product. The picker picks the item, waves it under a barcode scanner, and drops it in an outgoing bin. Repeat for 8 hours. The job requires no more than a room-temperature IQ. Machines should think. People should work.

Amazon keeps trying to automate that step.

I think the issue is that a lot of times they get impacted, where they are basically sideways cramming into another tooth, and it's a lot easier to remove them before that happens than afterwards, which means dentists tend to be really aggressive about suggesting they get removed. One of those situations where you see the problem a lot so you think it's a bigger deal than it actually is. Like someone that works at a car dealer saying that every Whatever is crap because that's all the work on, despite it statistically not being worse than any other model.
Stripe Closed My Account
After three months of using Stripe, they conducted a routine credit check and requested three months of bank statements. Since I use a Payoneer receiving account, I provided a Payoneer statement covering this period. However, shortly after I uploaded the documents, my account was closed, with Stripe citing it as high-risk. I have never had a chargeback, and I run a legitimate web hosting business.

Note:Stripe asked for the statement from the bank used for payouts, which for me is Payoneer, so I sent that. If they’d asked for a personal bank statement, I’d have happily provided it, but their request specifically focused on my payout account.

Each to their own but I consider native applications a step down from web apps.

I also get to spend a lot of time with executives thanks to the blog's success, and part of it isn't just incentives, it's pure confusion. People have no idea what they're buying.

I also get invitations to "sponsor events" now, since people see "director" on LinkedIn and think I have way more money than I do. Their business model seems to be flattering executives by inviting them to events where they can network with other rich people, then ask me for "sponsorship" money so that I can go into the room and brainwash them with my marketing material. I might even try it at some point to see if that's an accurate read.

On my vacation in Cuba some years ago, I found out that there are quite many westerners going there to learns Spanish in Cuban educational institutions. There were also university students who were there to participate in vocational education in Cuba-specific product manufacturing like rum. AFAIK even in Soviet times there were friendship programs and partnerships with the West to build civil ties which facilitated student exchanges etc, so I wouldn't be surprised if there are for DPRK too. I also recall something about joint programs with Korea/DPRK/EU/US to do production in special zones inside DPRK.

Except for Americans, the place was full of western tourists like me and my HSBC cards worked just fine. Those insulated places might not be as insulated as the general perception leads you to believe. The internet situation was PIA, though I hear its much better now.

> Applying FEM to real-life problems can involve the resolving of quite a lot of "little" practical and theoretical gotchas, bugs, etc.

FEM at it's core ends up being just a technique to find approximate solutions to problems expressed with partial differential equations.

Finding solutions to practical problems that meet both boundary conditions and domain is practically impossible to have with analytical methods. FEM trades off correctness with an approximation that can be exact in prescribed boundary conditions but is an approximation in both how domains are expressed and the solution,and has nice properties such as the approximation errors converging to the exact solution by refining the approximation. This means exponentially larger computational budgets.
Given the amount of people blindly trusting the output, I think that a case could be made that guardrails are a necessity for LLMs.

I liked the Tesla snake robot for charging.[1] But it upset many people.

It looks complicated but is a rather simple mechanical design. There are several motors in the base pulling on cables. The arm itself is just segments, disks, and cables. So all the complexity is in the base, and you can surround that with a metal or concrete box to prevent damage. Arm replacement wouldn't be too expensive.

Tesla is now touting wireless car charging, but that's a lot of power to transmit through air.

From my experience operating it I reckon it does the following: after you fill it and start, it starts heating and measures the time it takes to reach 100°C. This allows it (in the rice program) to figure out the amount of mass present and adjust the simmering time under pressure accordingly.

Using the same trick (in alll programs) it figures out overfilling and aborts for safety reasons.

Edit: I think the only sensor needed is a temperature sensor.
You were asked for bank statements and you gave them not-a-bank statements from another online payment processor… from Stripe’s POV you look like a reasonable approximation of a money launderer.

A legitimate business should be able to provide statements from a legitimate bank on request. Assuming you are legitimate and your Payoneer account ultimately ties to an actual bank, appeal to Stripe with that extra data and plead overwork fatigue.
I download drivers straight from nvidia.com and it takes many steps: go to drivers page, choose product series, choose product (choices don’t seem to matter but who knows if that’s gonna change at some point), click start search, click on the search result to go to driver page, click download, run installer, click click click click click. It’s a hassle compared to updating just about anything else on my machines.

I only do it because (1) GeForce Experience requires logging in with Nvidia account and seems to log me out every time; (2) when GeForce Experience updates the driver it seems to pause forever doing god knows what between finishing the download and starting to install.

Wanted to share something we’ve been building—MagicSet—a platform designed to help companies actually connect with their leads. If you’re in B2B, you know the struggle of sending outreach that lands… somewhere in spam or just gets ignored because it feels impersonal. We’ve tried to tackle that head-on with MagicSet.

Here’s what we do differently:

Personalized Deliverability: We deliver emails through Amazon and Google servers, which helps get more opens by making sure emails actually get through—no sketchy domains or low deliverability rates.

Multi-Channel, Automated Follow-Ups: The platform handles follow-ups automatically across email, voicemail drops, and even direct mail. This way, we’re not just “checking in” on one channel; the leads are actually getting reminders on multiple fronts, which keeps us on their radar without feeling overly pushy.

Real-Time Analytics and A/B Testing: We offer real-time tracking and tonality testing, so you can tweak your messaging as you go and see what really works. You’re not just sending messages into the void; you’re building something that gets better each time.

Flexible, Pay-As-You-Go Pricing: There are no contracts or long-term commitments, which was super important for us. You pay only for what you use, so it’s pretty low risk to try out.

BYOL (Bring Your Own List): You can bring your own leads or let us help create lists. So if you’re already sitting on data, you can import it and start right away, but we’ve got you if you need some help building lists too.

This is ideal for teams that need more than just a one-size-fits-all solution—especially if you’re in high-ticket sales, consulting, or other B2B services where every lead counts. We’ve heard from early users that it’s helping cut down manual work and actually get more meetings booked with real prospects.

If this sounds like it could help, check out the demo at magicset.ai. I’d love to hear your thoughts, especially if you’ve been frustrated by the limitations of other platforms out there.

Thanks for reading, and open to any questions or feedback!
