  • can’t fuck off from our responsibilities when we can’t be arsed with minimal consequences

    This might be the most (long term) depressing thing about adult life. Having a class for a semester or a year means that the mental overhead of a class builds up but, when you’re done, that demand is gone and you start over without baggage next term. Jobs build up that overhead, but it just never lets off, ever, unless you quit to take a new job. Switching (professional) jobs is similar to a semester/year end and - esp if you can swing a couple weeks in between - gives you that re-zeroing and that little honeymoon period at the beginning like the start of a class when you don’t have homework yet. The difference is that the switch often occurs on a scale of a decade, not a year.



  • I think it doesn’t go far enough. Straight up, no one should be permitted to create or transmit the likeness of anyone [prior to, say, 20 years following their death] without their explicit, written permission. Make the fine $1,000,000 or 10% of the offender’s net worth, whichever is greater; same penalty and corporate revocation for any corporation involved. Everyone involved from the prompt writer to the work-for-hire people should be liable for the full penalty. I can’t think of a valid, non-entertainment (parody/humor), reason for non-consensual impersonation - and using it for humor or parody is a slippery slope to propaganda weaponization. There is no baby in this tub of bathwater.







  • If you’ve ever had a contact allow a service to read their contacts, you are in their database. That then gets cross-referenced with the (relatively few) online store providers the first time you use that address - or the obfuscated emailname.store@* version that was meant to serialize or identify spammers but which the simplest script can undo. Now your shipping/billing address, phone, and partial purchase history can be linked with every social media company that weird chick who did upside down keg hits with you that one night decided to allow contact access. Or your aunt Gertrude.

    And it’s not even that complicated. Are you in the contacts list of anyone who has ever used the internet? Google, yahoo, or microsoft definitely know who you are in their internal databases and can create a web of contacts and likely contacts just from a couple of emails. Heck, I remember when there were “contact synchronization” websites where you could transfer your contacts between gmail addresses, or to/from other mail services. It was free, so I can just about guarantee they’re selling all of your info, which has been checked and corroborated by however many of your contacts decided to use their services.



  • SMS and (at least for craigslist) voice 2FA doesn’t work with VoIP (Google Voice numbers, including numbers ported from mobile operators). IRS 2FA via SMS definitely doesn’t work, nor does Dunkin Donuts (which invalidates use of their entire app on all mobile platforms). Some services offer voice 2FA which will go through, and some offer email, but many don’t. Of course the vast majority of 2FA over SMS work with the major VoIP providers, but if you hit one where it doesn’t…there’s either no way around it or you have to wait for a snailmail 2FA token (IRS).


  • I currently have (almost) only VoIP numbers. My cell phone technically has a carrier number, but only my immediate family and two friends (8 people in total) actually have that number for my contact, and I keep it that way for safety/security purposes. As a result, I already can’t do things like try ChatGPT, use the some vendor apps, or get quasi-2 factor codes from several businesses - including the IRS. Their systems simply can’t interact across a VoIP gateway. There really should be a certificate authority for these things, but the POTS system is just so fucking old.



  • Storage and transport of H2 is a big deal because of the unique properties (very low transition temp/very high pressure for liquid). That generally means for a non-pressurized, non-cryogenic storage it has to be combined into another molecule and then catalyzed back out, real time, for use. And, of course, the ignition ratio range (4%-75% in air) means that it’s very easy to accidentally ignite a H2 leak; substantially easier than most other fuels, though this is mitigated by it’s density and ability to disperse in an unenclosed area.

    Production is theoretically energy efficient as you can create it with hydrolysis, but the cheapest way of producing it, by far, is cracking of methane, which requires a high temperature process to create. It may not produce a high volume of CO2, but it perpetuates the cycle of exploration and extraction of gaseous hydrocarbons and the related environmental dangers and downsides.


  • Entirely true, but since we’re talking volume, this is only a 25% increase in linear dimensions (for the advertised 2x increase) or 35% (for the 2.5X maximum slurry density). If we are limited to a specific height of retention, that’s 40% and 60% (rounded). Note: for structural capacity, like a tank, retaining a g=2.5 liquid requires substantially higher strength than a g=1 liquid (for a given retention height). Since this is the internet and should source my knowledge: I know this because I happen to be an engineer who designs retaining structures. Anyway…

    For the effective cost of creating and maintaining the slurry, maintaining the integrity of the system (and keeping out wildlife), and the cost of decommissioning the otherwise unusable fluid, you’re likely talking about a reduction in area of 20-38% (1/8) to switch from using plain water to this engineered material. I don’t disagree that there may be some edge cases where the increased risk and expense is justifiable, but it’s hard to see this being viable except as some kind of tech demo.


  • This is logically efficient from a technical standpoint, but from a practical perspective is a terrible idea. You’re only getting 2-2.5x th energy storage out of the process, but in return you’re effectively requiring that the entire fluid system be isolated from the environment. Toxicity aside, you can’t do anything with the fluid outside of the system. It’s probably not something you want local fauna drinking, nor do you want even the slightest chance of this leaking into the local aquifers. I presume that, if it’s not fully isolated, the fluid mix balance would have to be adjusted to offset evaporation of the water. And if the plant turns out not to be as great at you hoped hat do you do with the fluid?

    Some numbers - a quick google says “According to Ofgem, the typical household in Britain uses approximately 2,900 kWh of electricity annually.” I’m going to round that up to 8kWh/day. For a small village of, say, 1250 homes and a three day storage capacity, that’s 30MWh. 1MJ (MWs) is 1000kg (one metric ton) stored at 100m - the upper end of this project. Since 3600 seconds per hour x 1MWs = 1 MWh, and we want 30, that’s 1MT x 3600 x 30 = 108,000 Metric Tons of this high density liquid needed for a small project to put a 3 power day buffer in place for a town of 1250 houses. WTF are you going to do with 108,000 metric tons of high-density fluid if you decide is isn’t working? Your reservoir would only need to be 25% bigger (wider, longer, and deeper/taller) to just do the whole thing with water and you wouldn’t need to figure out how to get 3500 full size tanker trucks to transport it all away somewhere for a different project for for de-slurry processing.
