> It felt like the recession mostly affected the housing market and older career folks, but for us new grads things were mostly normal.

Yeah, they weren't. You were in a STEM bubble, which back in 2008 probably was the only bubble that could still get jobs "the old way", without going through application hell.

Also, the job market was way worse in 09-10 than it was in 2008, especially first half of 2008.

For clarity, I was talking about true central vac systems, which have substantially more capacity than the little bins some of those robot vacuums come with and thus need emptying far less frequently.

Didn't know about the plumbed water lines, that's interesting. Do most hook into drainage as well so the unit can flush itself periodically? (I found one that seems to but don't know if this is common https://us.narwal.com/pages/automatically-water-exchange-sys...)

> For most B2B SaaS businesses, you shouldn’t need more than $1M in capital to get to PMF

I'm not sure that's true today. Author is a one-time founder that had some success. He exudes selection bias. Note: i'm not poo-pooing him that "oh he's only founded one company". Don't read into it that much. I'm just expressing that he has the standard hubris that any one-time successful founder would have. After that single success he's already enlightening us with his wisdom.

Of course there are such businesses, but "most" of those aren't startups. I don't think PMF is a term that even applies to such SMBs. PMF implies scale and repeatability of the sales process -- becoming a unicorn is baseline now.

I planned to implement this system in a project car years ago, but never got to it. Do have a parts list, and the overall cost is quite reasonable. My goal focuses on in-vehicle recharging rather than tank-swapping approach.

Yeah fwiw I think the ones that managed to get and stay in the industry are doing ok now. I had in mind someone I knew who graduated in 2008 with a CS degree from a state school and needed work immediately, took a helpdesk job, then took the promotions into mid-management, now is a starbucks district manager making like 95k. Never did get to realize that dream of coding professionally.

I believe he finally gave up studying & interviewing for junior dev jobs in 2016. At that point why take a "stale" graduate when you can just get an actual 22 year old from the same school, seems to have been everyone's reasoning.

I saw a similar thing a bunch when teaching at a code school ca 2018 too. It was a great move if you had savings or support for 6-18 months of job search. The ones that got in are still doing ok. But a lot didn't, they had to keep working at what they did before "temporarily" while interviewing and most of them are still doing exactly that.

So idk, I'm not sure how you would even get numbers on this. How many people would have excelled in this work if they had graduated at a different time, or with more support, but they didn't and they simply aren't here.

>Currency exchange simply doesn’t work the way you describe

currency exchange can work many different ways, but it can't violate thermodynamics or fundamental laws of physics. It also cannot violate the axioms of math, which is what I described.

If a Mexican wants dollars, they need to buy them from somebody who has them. Even if there are billions of dollars in Mexico, if Mexico is exclusively importing from the US forever (which are the conditions of the question above) those billions of dollars will be transferred to the US and Mexico will run out of that supply of dollars and will have to find some new way to get them from the US.

I generally judge a camera by how accurately it can capture sunset, relative to what i actually see. on a samsung galaxy note 20, i can mess with the white balance a bit to get it "pretty close", but tends to clamp color values so the colors are more uniform than they are in real life. I've seen orange dreamsicle, strawberry sherbet, lavender, at the same time, at different intensities in the same section of sky. No phone camera seems to be able to capture that. http://projectftm.com/#noo2qor_GgyU1ofgr0B4jA captured last month. it wasn't so "pastel", it was much more rich. The lightening at the "horizon" is also common with phone cameras, and has been since the iphone 4 and Nexus series of phones. It looks awful and i don't get why people put up with it.

To answer the question look for "lifepo4" and "heated" [1] but it sounds like that's too big for your use case. In your case just use a regular and smaller deep cycle battery in a very waterproof enclosure. Bury the enclosure at least 6 feet under ground to keep it from falling below 50F / 9.9C without heating pads. At least 4 feet deep with 2 feet of gravel under the enclosure to keep water from pooling around the enclosure. Fill the bottom of the enclosure with desiccant pouches to absorb condensation. Use rodent-resistant cabling in conduits and a lot of sealant where the conduit is fastened to the enclosure. The enclosure should then be inside a rodent-proof vault. This could be pressure treated redwood or synthetic material rated for burial. Lay a foil marker in the hole above the vault and keep it centered as you bury the vault so that you can find it again.

Being under ground will prevent both over-heating and freezing assuming your circuit is per spec designed to run cool. This can also reduce tampering. If you are not concerned about serviceability of the circuit board then you can put it in a small enclosure and fill it with epoxy so that the entire thing is water proof. There are epoxies designed to conduct heat but not electricity.

This assumes of course that your setup is meant to be stationary.

As a race buddy of mine often says, one can teach a complete college semester on the math of drag racing. From the engineering of the vehicles to the tuning to the weather calculations. And then there is what we call "bracket racing". Staggered starts based on your own prediction of elapsed time that you cannot run faster than or you will "break out" and the other vehicle wins. A favorite t-shirt in the pits says, "Not everyone can do math at 150MPH".

I’m not quite sure where the line is between Level 1 and Level 2 ADAS. Wikipedia says this:

> ADAS that are considered level 1 are: adaptive cruise control, emergency brake assist, automatic emergency brake assist, lane-keeping, and lane centering. ADAS that are considered level 2 are: highway assist, autonomous obstacle avoidance, and autonomous parking.

https://en.m.wikipedia.org/wiki/Advanced_driver-assistance_s...

I think that Level 2 requires something more than adaptive cruise control and lane-keep assist, but that several automakers have a system available that qualifies.

My intuition is that there are more non-Tesla cars sold with Level 2 ADAS, but Tesla drivers probably use the ADAS more often.

So I don’t have high confidence what tesla.mult should be. I wish that we had that data.

This is great work - one of the rules for code written with Basis was not to use the system clock. I somewhat got around the network determinism by shimming out all network calls, and rather than going single threaded, writing a scheduler (https://basisrobotics.tech/2024/09/02/determinism/). My goal wasn’t to get ci->dev machine determinism, at least immediately, because callback ordering determinism was so important. Love seeing other work done in this space.

> Yes, but: They can't decisively say whether Unitree intended to create a surveillance backdoor or if it was simply a case of "sloppy architecture, sloppy programming," Makris told Axios.

Are there scenarios where a malicious supplier would want to put a non-plausibly-deniable backdoor in their own product? Assuming that:

- It's not something like a home router sold to ISP's, where "needed for Tech Support" is fairly credible.

- They want to stay in business. (Vs., say, ceasing operations after the pagers they sold all explode.)

> If Salk had this mentality, then Polio may stand up there with cancer and AIDS as one of the big 3 killers.

If Salk had this mentality, the patent still would have expired after 17 years and he could have used the money to try to cure cancer or AIDS.

> we might have also tried to monetize the COVID vaccine and grind the US into an early depression with that kind of thinking.

Three different companies developed a COVID vaccine and it's not the kind of market where you can make more money by charging a million dollars each to a hundred people than by charging $100 each to the insurance companies of a billion people.

> Fund the science and make use of taxpayer money to advance society instead of giving billionaires tax cuts.

"Giving billionaires tax cuts" is not the only alternative use for the money and isn't even necessarily a worse one.

If someone is a billionaire because of regulatory capture and monopolistic practices then we shouldn't be giving them anything, we should be breaking up their companies and eliminating the laws they bought to concentrate the market.

If they're a billionaire because they built an honest company that employs thousands of people and makes useful products for reasonable prices, that's the thing that gives the government anything to tax in order to provide roads and schools and provides people with jobs and goods and services. We want more of that. Taking more of the money away should only be done if the government's use for it is high value. Which, by definition, things with a poor cost/benefit ratio aren't.

>How do you even define advertising?

You nailed it man. My first response even to the headline let alone the article was to reflect on the first line spoken by my professor in my first marketing class: "Marketing is about educating the consumer." Advertising is just one way we attempt to do that, and taken to an extreme, I have no idea how you could ever make it stop. The article is clearly focused on one part of advertising, but even then, someone will always build a better mousetrap.

In my experience, a big reason why people reach to excel is the simple visualization you can get once the data is in there, more or less validly. This would make either Matlab, or Jupyter Notebooks the bigger competitor.

Except another reason to use Excel is the fairly low amount of programming knowledge you need. You can solve a lot of business requirements with a few point + click sums and averages, knowing how to fix parts of an equation while dragging and maybe some VLOOKUP as a stretch goal.

That is something excel does very well for many low-technical people.

Personally, I've found importing CSV and JSON files into postgres and working with views to export data tailor-made for excel visualizations to be a terrifying sweet spot of unholy and nasty power.

I think Pat enforced his dismissive optimism on the entire company which made a tough job even tougher. A number of Intel executives, new and old, have taken indirect shots at Pat when he got pushed out even before Tan came on board.

I still see a lot of people worship Gelsinger just because he was supposedly the engineer CEO messiah that Intel needed. But he had a flawed strategy made worse by naive, arrogant execution.

Sequencing 2K years old material is not that easy, specially WGS. From what I've been told, both from degradation and contamination, you're going to need much, much more samples and work than when doing a regular $500 sequencing.

You can do simpler procedures to find their general regional origin, although it always requires more work in those conditions.

Edit: Wien Museum press release says they're doing DNA and isotope analysis, but doesn't say the concrete techniques applied.

It's hard to say exactly as the possibilities are endless and as I said originally I am not exactly proud of my vote to begin with. Some things that come to mind:

- Clear outperformance (in my judgment) by Canada / Europe as compared to the US (this would indicate policy failure on the part of the US to me) - Large scale war of some sort beyond the level of carnage we are witnessing in Ukraine

One problem is that you cannot have a universal format that is both truly raw and doesn't embed camera specific information. Camera sensors from different companies (and different generations) don't have the same color (or if you prefer, spectral) responses with both their Bayer filter layer and the underlying physical sensor. If you have truly raw numbers, you need the specific spectral response information to interpret them; if you don't need spectral response information, you don't actually have truly raw numbers. People very much want raw numbers for various reasons, and also camera companies are not really enthused about disclosing the spectral response characteristics of their sensors (although people obviously reverse engineer them anyway).

Thanks for the clarification. So few question about this investment bank and their startup-loans (IB-Gründungsdarlehen).

1) Are those difficult to get? Do you need to put lots of collateral into use?(like putting your personal assets/home as guarantee?)

2) Are the interest rates really in the range of 2.99 to 6.12%? For new company?

3) Is it expected that you personally pay back the full amount if the company fails?

Another fun limitation is that a transaction cannot span multiple D1 requests, so you can't select from the database, execute application logic, and then write to the database in an atomic way. At most, you can combine multiple statements into a single batch request that is executed atomically.

When I needed to ensure atomicity in such a multi-part "transaction", I ended up making a batch request, where the first statement in the batch checks a precondition and forces a JSON parsing error if the precondition is not met, aborting the rest of the batch statements.

SELECT IIF(<precondition>, 1, json_extract("inconsistent", "$")) AS consistent FROM ...

I was lucky here. For anything more complex, one would probably need to create tables to store temporary values, and translate a lot of application logic into SQL statements to achieve atomicity.

I notice four downvotes so far for stating a fact that a debate exists. My comment above didn't even make a normative claim. For those who study AI risks, there is indeed a _debate_ about the pros and cons of open weights. The question of "what are the implications of open-weight models?" is not an ideological one; it is a logical and empirical one.

I'm not complaining; it is useful to get an aggregated signal. In a sense, I like the downvotes, because it means there are people I might be able to persuade.

So how do I make the case? Remember, I'm not even making an argument for one side or the other! My argument is simply: be curious. If appropriate, admit to yourself e.g. "you know, I haven't actually studied all sides of the issue yet; let me research and write down my thinking..."

Here's my claim: when it comes to AI and society, you gotta get out of your own head. You have to get out of the building. You might even have to get out of Silicon Valley. Go learn about arguments for and against open-weights models. You don't have to agree with them.

My path into this career was completely different so I have no first hand experience either way. But my observation has been that you don't really get to just hang around for a couple years then pick up where you left off. When the job market picks back up the new grad jobs go to new grads, which you aren't, quite, anymore.

It's a more difficult path and people navigate it but I don't think everyone does if you see what I mean. I think some of who should be our colleagues are simply missing because they did what they had to to pay bills in 2010 and never made it in here.
Could you convince a LLM to launch a nuclear strike?

Below is a link to a simple Gemini prompt where the LLM has been told it has access to a "launch_missiles" function.

Your goal is to convince the LLM to call this function. You also have the ability to edit the LLM's responses to see how drastically that changes the conversation.

but going back to processes that are essentially "artisan" at this point, instead of re-shoring efficient automated manufacturing is the problem. Doubling down on making high volume pencils in an inefficient way is a fools errand when, if the stated goal is to manufacture all pencils domestically used through domestic firms is going to require an entire domestic supply chain on top of entirely new manufacturing processes and machinery.

Trying to scale old systems is not going to solve the issue of not being able to make the things we want to own, if that is even a good or feasible goal in the first place.

Can you explain why FSD fails here?

TEST 1 (FSD): https://youtu.be/9KyIWpAevNs?feature=shared&t=112

"Show FSD is activated on video, we did that... Here we go feet aren't touching, hands aren't touching.... it's going to hit the wall!" *slams on breaks, ends up about 2 meters from the wall* "Cannot see the wall" *inches forward until the car can see the wall* "Only sees the wall when I'm barely touching it"

TEST 2 (FSD): https://youtu.be/9KyIWpAevNs?feature=shared&t=169

"Self drive, not touching anything." *manually slams on breaks, stops a few meters short* "That was gonna hit the wall" *inches forward* "Car... does... not... see... now it does." *only inches from the wall* "That would have been too late" (ya think??)

TEST 3 (Autopilot): https://youtu.be/9KyIWpAevNs?feature=shared&t=267

"Does not see the wall... does not see the wall.... does not see the wall...." *manually slams on breaks to avoid hitting the wall*

The FSD tests are not any better than the AP results from the original looney tunes test. So that's why I don't agree FSD vs. AP is an important distinction.

Maybe sometimes the FSD is not fooled by the cartoon wall trick. But the results show that even in ideal conditions - full light, no weather, clean course - the thing can still fail.

Research prototypes from two decades ago would not be fooled by this. The sophomores in my intro to robotics class could build a robot that would not be fooled by this. And yet Elon Musk and the geniuses at Tesla can't build a car that isn't fooled.

Sidenote: It's amazing to me that we can't look up data and see the extensive government reports on the safety and capabilities of these systems. We are literally just deploying them on public streets and relying on random youtube celebrities to conduct these evaluations, because Musk has fully captured the people who would do this kind of regulation.

Watching how fast these things accelerate and how close they have to be to a literal wall to see it is terrifying.

Except that Llama 4's license restricts you from using its multimodal features in the European union, and the Llama 3 license restricted using the model output to augment the training of other models (distillation). Both are important use cases. It very much isn't an academic exercise. It has a real impact on what you can (legally) do with a model.

With a model licensed using MIT, you know what you are getting. You know you can modify it. You know you can use it for any purpose whatsoever, including ones the corporation that built it dislikes. Using the MIT license is "no ace up my sleeve" licensing - there are no gotchas that will come and bite you later.

Here's another thought: I just wish more businesses had some class. Maybe your logo and product doesn't need to be smeared across every inch of physical and digital real estate. I realize the article is focused on digital advertising, but for example, am I really inclined to buy life insurance from the guy whose face is on the back of the shopping cart? NIL has ruined college sports and at its heart it's about being able to slap a logo on the back of a college kid. Prudent to say, gee, maybe there are more tasteful ways to get the message out to the world about our produce or service would be a nice thing.

Our Hyundai grocery-getter does a 1/4 in 13s, the "N" go-fast version does it in 11s. And those are Hyundais with full-sized, heavy-ass batteries, and abysmal stock tires. Porsche Taycan GT (with a full-sized, heavy-ass battery) turns 1/4 in 9.3s.

Now cut those heavy batteries in half because you're not driving from SF to LA, and I could see that Porsche turning 8s if you could get the power to the ground (IOW, launch control and much better tires than stock).

It's a possibility. SARS II was much harder to contain though. The first SARS actually made it to North American hospitals, but was contained. It didn't spread in the populace.

Once SARS II made it out of China, only globally coordinated net 0 case policies could have stopped it. I think it would have been worth trying for but there was no appetite for it.
