Thanks for the analysis and insight!

I found at least one of the posts, and you’re right, that’s not really what impressed them. It just stuck with me because I’m a hardware girl.

I’d believe it because I remember the same being true for TikTok.

I don’t have the links on me right now, but I remember clearly that when tiktok was new, engineers trying to figure out what data it collected found that the app could recognize when it was being observed, and would “rewite” itself to evade detection.

They noted that they’d never seen this outside of sophisticated malware, and doubted that a social media company had the resources to write such a program.

In hot weather, I use silica gel neck wraps, which slowly release water to keep you cool (if soggy). I really want to try making an equivalent out of sodium sulphate gel and see how it compares.

That’s the only way to offer free services?! What about donation-based models? Maybe Mozilla could have set up something like what Brave has, except not based around a sketchy cryptocurrency.

Please correct me if I’m mistaken, but I thought Brave only gave donatable tokens to users as a reward for watching ads… ads which Brave curated for the user based on their activity. It’s just targeted ad revenue with extra steps.

At first blush, it seems to me that both Brave and Anonym want to be the middleman for targeted advertising. What am I missing?

Makeover day!

I admitted to some of my friends that I’d love the chance to get some makeup tips from them, and they pounced on that with unexpected enthusiasm. They scheduled an appointment at the mall, saying it was a rite of passage. So I got my makeup done by a professional makeup artist who taught me how to do things like foundation matching and mixing color changer, all while a gaggle of absolutely wonderful people took notes and told me I looked beautiful.

I’ve been running on that high for weeks now.

Solid point. A laptop battery is around 60Wh, and charging that in 1 minute would pull 3.6kW from the outlet, or roughly double what a US residential outlet can deliver.

Supercaps stay pretty cool under high current charging/discharging, but your laptop would have to be the size of a mini fridge.

The research paper itself was only talking about using the tech for wearable electronics, which tend to be tiny. The article probably made the cars-and-phones connection for SEO. Good tech, bad journalism.

Yeah, this matches my experience.

A supercapacitor buffer will cost around twice as much and deliver around 1/10th the watt-hours of a similarly-sized lead acid battery. And lead acid isn’t exactly great to begin with.

Capacitors are useful, but only in applications where the total amount of energy stored is more-or-less unimportant.

Yeah, no. This is not about chargers or batteries or phones or cars. This study is about improved charge/discharge rates for supercapacitors.

Supercaps have very high flow rate, but extremely low capacity. Put them in a phone or a car and it would run very fast for five minutes. Supercaps are useful, don’t get me wrong, but they’re not batteries.

Very cool research from UC Boulder, but the journalism leans way too far into clickbait.

I’d argue your SO might not be displaying neurotypical behavior.

Between 50-85% of autistic spectrum people (plus a significant portion of people with PTSD or depression) experience Alexithymia, or significant difficulty in recognizing and analyzing their emotional state.

When I’m feeling bad, my SO frequently assumes I’m withholding the reason from him in some sort of passive-aggressive mindgame, and I have to remind him that I barely know what my mood is, let alone what’s causing it.

I’m getting better at it, but it’s a lot of work and I still regularly mistake stomachaches for anxiety.

When a smaller nation aligns itself with a larger empire or coalition, it will gravitate towards that collective’s philosophy. Sometime’s it’s imposed through political or military pressure, or “encouraged” through subversion, but it can just as easily happen through the natural influence of a larger and more prolific culture.

Historically, there have been more socialist and/or communist states associated with the USSR than not. Especially when measured by population.

Sodium batteries are commercially available as of early this year. I’ve seen Hakadi and Sriko tested independently on Youtube – they’re the real deal (sodium has a unique charging curve), but they have the same/similar organic electrolyte as LFP cells (I believe Natron uses PBA on both anode and cathode plus water-based electrolyte).

Youtube videos often gloss over the details for the sake of uninhibited futurism.

Large-scale hydrogen electrolysis has a cost of around 55kWh/kg, and when you combust the H2 directly you get about 39kWh/kg back. Without compression/transport, using H2 as a heating fuel is 71% efficient.

H2 is usually compressed for transport. Compression of 1 kg of H2 to 700 bar costs about 5kWh of additional electricity. I’ll spare you the calcs, but truck transport is under 1kWh/kg H2. This reduces our efficiency to 39kWh/61kWh or 64%.

Converting H2 to ammonia takes the place of the compressor and truck. 2 mols of ammonia burn for 162kcal, less than the 204kcal you’d get from 3 mols of H2. The Haber-Bosch process reduces output to 31kWh per kg of H2 put in. This reduces out efficiency to 31kWh/55kWh or 56%.

With currently-proven cracking technology, it costs around 23kcal/mol of ammonia, reducing overall efficiency to about 55%. It is more effective to burn ammonia directly than to convert it into H2 and burn the H2.

Using ammonia as a transport medium removes a bunch of technical problems, but it introduces new ones. It’s corrosive, it’s toxic, it burns eyes/lungs/skin, and it wastes more energy than you’d think.

Despite the fediverse’s reputation for leaning leftist, I feel like such a stranger with how often I find myself arguing that the collective action and solidarity of the working class can and has improved the material outcomes of nations, with or without the capital of the owner class, and with or without the approval of the government.

Fight in whatever way makes sense to you. Some people will carpool or use less hot water. Some will put peer pressure on wealthy acquaintances. Some will alter design requirements or RFQs. Some will [redacted] a pipeline. It all works towards the same end.

Yes, this is the fault of the owner class, but who do you think is going to force them to change if we all sit on our hands and say, “I dunno, man, that sounds like someone else’s responsibility.”

I will say this about Biden: the dude’s downright sneaky. It seems to be his administration’s main strategy to publicly walk back a major agenda point, let right-wingers celebrate, and then after the media hype (and potential for right-wing backlash) dies out, quietly split it up into smaller programs that get pushed further than the original agenda ever could.

• He blocked the rail strike, but then went back and ensured the unions got their sick leave anyway.
• He approved historic oil projects, but then went back and curtailed more oil production than he ever approved.
• He let Senator Manchin gut EV tax credits, but then spread that money out in the IRA and IIJA with green infrastructure funding so comprehensive that it has international attention.
• He’s been criticized for being soft on China’s military (by the right) and emissions (by the left), but the CHIPS Act and FABS Act and ban(s) on chip and tooling exports have all but eliminated China’s greatest source of geopolitical leverage: their nascent monopoly on electronics.
• The SCOTUS struck down student loan forgiveness, but Biden went back and forgave more, this time splitting it into multiple smaller programs that are harder to stop.

So yeah, it seems on-brand that the Biden administration would push for LNG exports after Russia’s invasion of Ukraine, and then go back later and curtail them instead.

Exactly. Hertz vocally blames higher repair costs and long repair times for the Teslas that make up the bulk of their EV fleet. Other EV manufacturers don’t share those problems.
