It’s this already debunked by the famous Danish McDonald’s example?

This is also simple math.

Let’s say you buy a product for $100 with these example costs:

$30 of the price goes to labor

$30 of the price goes to rent/utilities/“keeping the lights on”

$30 of the price goes to inputs (materials)

$10 of the price goes to profit.

Let’s say wages go up by 20%.

Labor goes up to $36, now your price is $106.

Wages went up by 20% but your price went up by 6%.

Maybe we have to add the labor of the input materials, but a lot of input materials have low labor costs than finished products in the restaurant industry. E.g., a tortilla from a tortilla factory doesn’t have 30% of its price represented by labor cost, since it’s made on an automated assembly line. Still, for ease, let’s just say our input materials went up by ~6% to $32

At the end of the day your total cost of your product went up less than 10% but all the employees got a massive 20% raise.

But also, if any of these employees were already making above minimum wage, then we can’t even assume that the purchase price is going up by 6%. In reality it’s probably only going up by 0-3%. Then you’ve getting the benefit of not starving your poorest people and having them depend on government aid.

What’s the point of having a low minimum wage if you’re just going to supplement it with state benefits anyway? Walmart hires tens of thousands of employees who work full schedules but depend on government assistance to survive. Why not just pay them a living wage out of Walmart’s pockets and remove the government assistance from the equation?

Part of the size was the internal power supply. And that thing got hot, too. I used them at school, but at home only had the smaller 1541-II with an external power brick.

The Apple II disk drives, on the other hand, were not only cheap (Apple was different then!) and fast, but were powered by the ribbon cable connecting them to the computer.

> why is it not trivial to add a path stage as an alternative to the vertex stage?

Because paths, unlike triangles are not fixed size or have screen space locality. Paths consist of multiple contours of segments, typically cubic bezier curves and a winding rule.

You can't draw one segment out of a contour on the screen and continue to the next one, let alone do them in parallel. A vertical line segment on the left hand side going bottom to top of your screen will make every pixel to the right of it "inside" the path, but if there's another line segment going top to bottom somewhere the pixel and it's outside again.

You need to evaluate the winding rule for every curve segment on every pixel and sum it up.

By contrast, all the pixels inside the triangle are also inside the bounding box of the triangle and the inside/outside test for a pixel is trivially simple.

There are at least four popular approaches to GPU vector graphics:

1) Loop-Blinn: Use CPU to tessellate the path to triangles on the inside and on the edges of the paths. Use a special shader with some tricks to evaluate a bezier curve for the triangles on the edges.

2) Stencil then cover: For each line segment in a tessellated curve, draw a rectangle that extends to the left edge of the contour and use two sided stencil function to add +1 or -1 to the stencil buffer. Draw another rectangle on top of the whole path and set the stencil test to draw only where the stencil buffer is non-zero (or even/odd) according to the winding rule.

3) Draw a rectangle with a special shader that evaluates all the curves in a path, and use a spatial data structure to skip some. Useful for fonts and quadratic bezier curves, not full vector graphics. Much faster than the other methods for simple and small (pixel size) filled paths. Example: Lengyel's method / Slug library.

4) Compute based methods such as the one in this article or Raph Levien's work: use a grid based system with tessellated line segments to limit the number of curves that have to be evaluated per pixel.

Now this is only filling paths, which is the easy part. Stroking paths is much more difficult. Full SVG support has both and much more.

> In fact, you could likely use the geometry stage to create arbitrarily dense vertices based on path data passed to the shader without needing any new GPU features.

Geometry shaders are commonly used with stencil-then-cover to avoid a CPU preprocessing step.

But none of the GPU geometry stages (geometry, tessellation or mesh shaders) are powerful enough to deal with all the corner cases of tessellating vector graphics paths, self intersections, cusps, holes, degenerate curves etc. It's not a very parallel friendly problem.

> Why is this not done?

As I've described here: all of these ideas have been done with varying degrees of success.

> Is the CPU render still faster than these options?

No, the fastest methods are a combination of CPU preprocessing for the difficult geometry problems and GPU for blasting out the pixels.

Some relevant job ads for Anthropic:

https://www.anthropic.com/careers/jobs/5025624008 - "Research Engineer – Cybersecurity RL" - "This role blends research and engineering, requiring you to both develop novel approaches and realize them in code. Your work will include designing and implementing RL environments, conducting experiments and evaluations, delivering your work into production training runs, and collaborating with other researchers, engineers, and cybersecurity specialists across and outside Anthropic."

https://www.anthropic.com/careers/jobs/4924308008 - "Research Engineer / Research Scientist, Biology & Life Sciences" - "As a founding member of our team, you'll work at the intersection of cutting-edge AI and the biological sciences, developing rigorous methods to measure and improve model performance on complex scientific tasks."

The key trend in 2025 was a new emphasis on reinforcement learning - models are no longer just trained by dumping in a ton of scraped text, there's now a TON of work involved designing reinforcement learning loops that teach them how to do specific useful things - and designing those loops requires subject-matter expertise.

That's why they got so much better at code over the past six months - code is the perfect target for RL because you can run generated code and see if it works or not.

If Lysenko Jr wants us all to eat steaks, he should get to work on either eliminating ticks, or creating a cure for alphagal (alpha galactose) allergy transmitted by many ticks. I've had to stop eating beef (my wife gives me a little bite of her steak once in awhile), along with lamb and pork (pork seems to be less of a problem than beef, but I still have to eat it in moderation).

In case you're not familiar with this allergy, it doesn't behave like other food allergies: instead of getting instant symptoms, it hits you hours later, making it hard to figure out why you suddenly have hives---unless you already know about alpha gal.

Of course that's a factor. The article doesn't get into causes much, but this anecdote provides a bit of color and gives a vague sense of the scale of a few factors:

> Onions that cost $9 a sack before COVID now run $80. Beef is up more than $2 a pound, adding $6,000 to his monthly costs. Labor adds another $3,000.

So, ehhm, yeah, I sort-of question the data in this article. A US$5.50 burrito in Downtown SF in 2014? Nah... even Taco Bell takeout was already more expensive than that at the time.

Also: sure, some places overdo it on the pricing: I distinctly remember walking out of a Rotterdam (somewhere in The Netherlands) establishment due to them charging 25 Euros for a lunch sandwich, like 2 decades ago, despite this not being a fancy place at all. No inflation in sight, just greed and/or an inability to read the target audience...

I see how the article is framed, but I see a lot of good things in that timeline:

MAHA Commission assessing health risks from food ingredients and chemicals and developing a strategy to combat childhood chronic disease
Closing the GRAS loophole
Phasing out synthetic food dyes
$235 million specifically aimed at improving nutrition, controlling food additives and addressing food safety
$15 million specifically for modernizing infant formula oversight
$7 million to support critical laboratory operations

For me, the salient turning point was the Reagan administration, which began cultivation of the attitude that government collection of routine data on weather, railroad traffic, crime, health, ... was intrinsically suspect, expensive, and partisan, rather than a public service and scientific adjunct.

I'll say this a different way: my personal opinion is that there's at least a whole book that deserves to be written on the documentable underinvestment in government measurements of national characteristics. We've trained a couple of generations--especially the most recent one--that rhetoric, rather than analysis, is the appropriate basis for policy decisions.

Skepticism, or at least reserve, in the face of expertise, can be a healthy impulse. It's simultaneously a leading slogan of the jingoistic playbook of authoritarians. Anti-intellectualism isn't a solvable problem: it's an ongoing temptation that every society needs to address in contemporary terms.

They're looking at actual 2014 menus.

But yeah, it's likely an outlier in 2014 to be that cheap. More like $7-8.

Locally (not in SV), one can still find "cheap" burritos at Mexican joints. By cheap I mean $11-12.

In one local restaurant, they bumped up burritos from about $11 to $18 within a year. I stopped going there.

Many things have been practiced/studied for thousands of years - that alone isn't interesting or valuable imo.

What are the objective benefits of meditation - what is the exact/specific process and what specifically does it accomplish?

I can see how being in a silent reflective state and similar practices could have various effects and benefits (not that I know specifically what those are) - but what separates me zoning out in the shower/on the bus from actual meditation? How is 'guided' meditation when you're actively listening to someone else even the same thing?

Whenever I ask my meditating/'spiritual' friends about these things the response is basically vague undecipherable gibberish and allusions that it is unexplainable to someone like me who is not ready to accept the truths lol.

Thanks for your kind words. I've added mail to profile, feel free to reach out.

If you are into air quality monitoring you might like homeassistant either with DIY sensors based on esphome (quite easy if you like very basic tinkering with low voltage) or with some off-the-shelf IOT products. If you just want to have a reliable CO2 sensor I can recommend the aranet4, but unfortunately those are quite expensive.

I had some electrical sockets which were super corroded from the humdity, so that the copper wire turned black even though the plastic wrap of the cable was still on it. The humidity must have moved up the cable for ~10cm. The mold damage that I found a year later was at the same wall, but I didn't mentally connect these two things at the time.

It is bad. Its fine when you read the opinions for the first time, but after a while you notice over half of the discussion is just repeating the same off-topic talking points over and over and over again on every submission.

"Off topic but...", "The CSS on this site...", "Have you noticed this web page is 5/10/20MB...", "Why is the webpage making 20+ requests...", "Microsoft bla bla bla...", "Elon Musk bla bla bla...", "I havent used cryptocurrency at all and it is bad because..."

All of these on some post about a new library release or government policy or social commentary.

I know the customer's couldn't care about the quality of the code they see. But the idea that they don't care about software being bad/laggy/bloated ever, because it "still solves problems", doesn't stand up to scrutiny as an immutable fact of the universe. Market conditions can change.

I'm banking on a future that if users feel they can (perhaps vibe) code their own solutions, they are far less likely to open their wallets for our bloatware solutions. Why pay exorbitant rents for shitty SaaS if you can make your own thing ad-free, exactly to your own mental spec?

I want the "computers are new, programmers are in short supply, customer is desperate" era we've had in my lifetime so far to come to a close.

These are great, thanks!
That GBA "butano" compiles with -fno-rtti -fno-exceptions, so it is not a C++ engine/library according to C++ standard! It is, however, an impressive piece of work.

The ESP32 SDK (I lol'd at your "even", those Xtensa/RISCV chips can even run linux kernel!) is extremely impressive - they support enabling/disabling rtti and exceptions (obviously disabled by default, but the fact they implemented support for that is amazing). So "real C++" is possible on ESP32, which is good to know.

For comparision, here are the minimum SQLite dependencies from the submitted article: memcmp() memcpy() memmove() memset() strcmp() strlen() strncmp()

Of course you could run javascript and erlang on MCU too, but is that API better than C? Your claim of "skill issue" sounds like RedBull challenge. Please let us unskilled people simply call library functions.

Worth noting that ruminants have less variance between "good diets" and "bad diets" for the animals than other animal protein sources. IE: you're better off with a grain fed steak than an unnaturally fed non-ruminant animal.

As to the calories, yes calories count, but the fact that it is calorie dense doesn't necessarily mean you should avoid it so much as be aware if you are mixing sources and having excessive meals. I know a lot of people on carnivore diets for inflammatory and diabetic control and the total calorie intake is less of an issue in those cases. Even with a pound of steak and a dozen eggs a day, weight loss is still happening for overweight diabetics on carnivore diets.

Just meat is very sating and impossible for most people to overeat in practice... at least from my own experience and exposure. The relative mono diet also helps with this.

Honestly, you can find studies to prove just about anything when it comes to nutrition. Too much money involved. Sometimes you have to use common sense or try different diets to see how your body reacts. I find "high fiber" and "low protein" to be a suspicious suggestion though. Protein generally has a small insulin response, your body actually needs protein, and if things like the "protein leverage hypothesis" are correct it can also help with satiety. Fiber, on the other hand, is literally food stuff that can't be digested. It can be helpful for your colon bacteria, but that's about it.

Just because an article comes from Harvard doesn't mean it's correct -- Harvard scientists were also behind the original food pyramid, and were likely paid off by the sugar industry.

There's more to manufacturing than just rebuilding factories. You need everything from supply chains (which are going to include some foreign materials in many cases), to people who want to work in a factory in 2026, to consumers who want to pay extra for domestically made products.

It's not as easy as saying "just tax imports" or "just tax offshoring" because that hits the average folks who are barely getting by, as every cost gets passed down to the consumer.

I live in a country that used to be heavily industrialized (back in the previous regime when the goal was to be self-sufficient). In the 90s we lost most of the domestic industry as the factories got privatized and opening foreign trade enabled cheaper foreign products to flood the market. Most factories were sold off or just went out of business.

There's been some success with small businesses doing manufacturing domestically but it's mostly niche and not near what it used to be back when every house had at least some domestically made clothes, furniture, electronics...

Labor is expensive, market small, taxes high, and lately even high energy costs and rising import fees on materials from abroad. Plus of course the fact that people can't afford to pay 5-10x for the same thing made domestically when they can barely afford the thing at 1x the price.

> My router assigns dynamic IP addresses, meaning my server location kept changing.

I've had a similar problem in the past. It turns out that most routers have a way to assign an IP address statically based on the MAC address of the requesting device without affecting the other DHCP devices on the network.

I do this for my pi-hole, my NAS and my gaming PC.

Have you tried Roo Code in "Orchestrator" mode? I find it generally "chews" the tasks I give it to then spoon feed into sub-tasks in "Code" (or others) mode, leaving less room to stray from very focused "bite-sized" changes.

I do need to steer it sometimes, but since it doesn't change a lot at a time, I can usually guide the agent and stop the disaster before it spreads.

A big caveat is I haven't tried heavy front-end stuff with it, more django stuff, and I'm pretty happy with the output.

Cook very large or numerous portions. Use what you need for 1 meal, freeze the rest to save for future meals. Based on how much your family eats in that first meal, divide up the remaining amount into that sized portions when freezing. Warm up the frozen food in the oven (still may take an hour, but you can do other things during that time).

Frozen vegetables are pretty cheap and easy to warm up quickly in the microwave or an air fryer. They may not be as good for you as fresh produce, but that can be a reasonable tradeoff based on the season and free time.

Chest freezers are reasonably cheap to buy (new or used) and cheap to operate, assuming you have the physical space and an open electrical outlet. They don't consume much electricity, mine uses about 75W for the compressor (when it's running, which is less than 50% of the time) and about 250W for the defrost heaters (which seem to turn on for about 15 minutes roughly once per day.

Steak is actually an excellent source of protein (and fat, if you get the fattier steak as you should).

Just because vegetables, lentils or nuts contain protein it doesn't mean it's the same/equivalent to the protein in an animal product.

Meat is actually super easy for humans to digest and it has no downsides to it. All vegetables on the other side contain plenty of anti-nutrients such as folate and oxalates.

Nice. I built something similar using a Rust-based daemon running on my Mac. It listens to the microphone state (not the camera) via a Core Audio property listener (AudioObjectPropertyListenerProc), rather than log monitoring or polling, so it works even when the camera is turned off.
When the mic status changes, the daemon toggles a light by sending a simple message via zigbee2mqtt.
I also installed a fire alarm plate above my door, powered by a cheap Zigbee socket, similar to this one: https://ampac.net/wp-content/uploads/2017/05/4210-0131-Warni...

Great. Now let's start replacing fast food places with places that still serve you quickly but serve healthy food. Complete meals of whole foods.

One of the problems with the way we live and work is that it's so easy to go for the quick option. If you're working 60+ hours a week or trying to run a busy household, unhealthy food options are really attractive for you because they're so convenient. People generally know what good food is, it's just that they make the sacrifice because there's other things going on in their lives.

I've said things like this before and people respond like "well, I run my own business and raise a family and volunteer at my church and so on and on... AND cook perfectly healthy meals 3 times a day!" That's awesome for you, you're amazing, but let's get real.

That sounds more like the fad Atkin's weight loss diet that said you could eat unlimited meat/fat/protein, but no carbs.

This new JFK Jr diet has something in common with the Paleo "cave man" diet, which at least makes some sense in the argument ("this is what our bodies have evolved to eat") if not the specifics. I'm not sure where the emphasis on milk/cheese and eggs comes from since this all modern, not hunter-gatherer, and largely unhealthy, and putting red-meat at the top (more cholesterol, together with the eggs), and whole grain at the bottom makes zero sense - a recipe for heart attacks and colon cancer.
