Yeah, I talked about how assets are different than things we need, like health…

The original comment references luxury assets like supercars. In the USA, the average adult needs a car of some sort to function in society, and often cannot afford the unplanned purchase of a reliable used car (let's call that $15K). Collision insurance that will cover most of the cost of a replacement car is a reasonable value for many people, and the insurance company doesn't have any special leverage like access to massive discounts on replacement cars (they may have access to modest discounts on repair services, but nothing like what health insurance has).

You just don’t understand it

I think I made it pretty clear I understand that for-profit health insurance is a scam because providers overcharge anyone who doesn't have it to an extreme degree. That's not the case for pretty much anything else.

For-profit insurance for most things isn't a scam. Insuring against the destruction of a house or car, for example is a calculated tradeoff; on average, you lose money (expected value is negative), but only a little at a time. In exchange, you get a guarantee that you won't lose an asset you can't afford to replace.

For-profit health insurance in the USA is a special sort of scam because they negotiate prices that aren't available to the public, often an order of magnitude lower.

If someone was going to reward me for burning a lot of tokens, I'd feed LLM output into the LLM input until they ran out of rewards.

Deathbeak XVII keeps coming up from behind the bench to nip at my butt

Of course he does. Your name is Grass. That's what they eat.

Using it as a laptop? In theory, a 10" screen thin and light laptop with the guts in the base instead of the screen is a better design. There aren't very many of those to be had, especially not for $90 on Ebay.

Watching videos during taxi, takeoff, and landing? The alternative is paying attention to the safety briefing. I think I won't.

Surface Go 2.

It wasn't a Linux tablet when it first arrived, but that was easy to fix.

[–] Zak@lemmy.world 3 points 3 weeks ago

Most models are just PCs. The cameras in my Surface Go 2 don't work out of the box on Linux, but everything else is fine.

The power supplies for those things showed up dirt cheap on Ebay at a time when 2A+ USB power supplies were premium items. I bought a bunch of them.

As the owner of a proper Linux tablet, tablets are for combining with keyboards for use as small laptops.

They're also good for watching videos during taxi, takeoff, and landing during which laptop use is forbidden.

That means if Google’s verification system gets widely adopted, browsing the web could become a headache.

Using a phone to scan a QR code in order to access a website on my desktop is a headache even if it has no dependencies in particular.

I enjoyed being able to safely ride my bike the 8 miles to school

Aside from the risk of the authorities treating it as child neglect, do you believe this would be less safe to do now? If so, why?

It seems very unlikely to me that the model itself has a list of banned words, and much more likely that a purported list is hallucinated.

If they did want to have a simple list like that, it would probably go in the harness rather than the model, and the model wouldn't have been trained on it, nor would a reasonably designed harness provide it to the model. Legitimate use cases, such as asking the model for a list of abusive words for use as a first pass in a filtering system could get tripped up.

As a test, I asked Perplexity to generate such a list. It did a bad job, including such words as abuse, hate, and threat which are far more likely to be innocuous than abusive. It did also include some highly offensive slurs that one would expect on any banned words list.

This LED has popped up a couple times and sold out quickly. I think it's expected to go into full production, but for anyone who wants to try one now....

 

The LG 32G810SA-W.AEU is available to me for 400€, which is half its typical price. My important use cases are photo editing and software development. I will be calibrating whatever display I buy using a spectrophotometer.

Specs, but here's a quick overview:

Spec -
Diagonal 32"
Aspect 16:9
Resolution 3840x2160
Panel type IPS
Color gamut 95% DCI P3
Refresh 144 Hz
Contrast 1000:1
Brightness 400 nits
GtG response 1ms
Connectivity USB-C DP + PD (65W), HDMI, DP 1.4, 2xUSB-A (downstream), ethernet
Features WebOS, "HDR400" (fake HDR), FreeSync, G-Sync

In the short term, at least, I'll be running it from a Thinkpad P14s gen3 (AMD), which will drive it at 60Hz. PD is nice, but 65W is a bit weak, and my laptop will drain the battery under sustained load. WebOS doesn't seem like something I'll ever use, and from what I've read, all "HDR" anywhere near this combination of size and price is worthless.

I've been known to do occasional light gaming and watch videos on my PC, which would be improved by the fast response time, but I think color gamut, viewing angles, and contrast get priority in roughly that order. I'm not finding better contrast without either a much higher price or much worse color.

 

The article speculates about the gosling's survival; the family was photographed yesterday and posted to reddit.

 

A family member gave me an old convertible Chromebook, which I (of course) installed Linux on for the fun of it. It has convinced me there's a place in my life for a Linux tablet, though it's not quite the right device for me.

The Surface Go 2 seems about right with less size and more memory than the Chromebook, but I figured I should ask if people like anything else. Here are some preferences:

  • 500-600g weight seems about right; the Chromebook is 1100g and that's a bit much
  • 10" or so, 3:2 or 4:3, nothing more oblong
  • Pressure-sensitive stylus support
  • Expandable storage - an SSD I can swap without a heat gun is ideal, but an SD card slot will do
  • Headphone jack
  • x86-64, not ARM
  • 8gb RAM
  • $100ish for used B-grade
 

My Opus BT-C3100 smells like magic smoke and looks like this. I suppose I could change these resistors and it might be OK, but I could also buy things.

I'm looking for 2-4 slots; it should fit protected 21700s; it shouldn't have a noisy fan that runs all the time like the Opus; USB-C input is preferred, but not required.

I'm broadly aware of what's on the market, but I want to know if you love or hate yours.

 

For background, it's hard to make a flashlight that works well on both AA batteries (0.8-1.7V potential operating range) and 14500 Li-ion batteries (2.8-4.2V operating range) given that white LEDs need about 3V.

For a long time, companies would make lights designed for AA using a boost driver that increases the output voltage, do just enough so it wouldn't burn out with excessive input voltage, and say that 14500 size Li-ion was "supported". Max output would, indeed be brighter, but low modes were usually far too high, and the flashlights could easily damage batteries that didn't have over-discharge protection.

The Skilhunt M150 was one of the first lights to do a substantially better job. Using a Li-ion battery, it sent the power through a variable-output linear regulator so both battery types could have reasonable modes, and it would shut off to prevent over-discharge. Several competitors use a similar approach today, but linear regulators are inefficient; they just turn the excess voltage to heat.

The ideal solution is either to use a higher-voltage LED configuration and boost the output voltage for both battery types, or to use a driver that can both boost (increase) and buck (decrease) voltage efficiently. The Emisar D3AA is the only light on the market doing AA/14500 with a high-voltage LED configuration (three in series for ~9V), and I believe the new M150 will be the first one using the buck/boost approach (though it's possible Zebralight has done it in the past).
