  • 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.


  • Clear containers for anything that isn’t commercially labeled. My wife used to wrap leftovers (or anything, really) in aluminum foil. more than two thirds of the time I’d end up throwing it out after a couple of weeks because, since nobody knew what was in the mystery packages, nobody ate it. I bought some glass storage containers (the kind with the plastic, locking lids) so it’s obvious what is contained within. A lot less waste.

    Also, I’ve got pull-out bottom freezer with one basket and one deep “bin” and shit got lost so I 3D printed dividers and organized it.


  • I had high hopes for Dex when it was first announced and I was on android for my phone, but dragging around a monitor was more work than just bringing my laptop. I got a 12.9" iPad a couple years ago as a portable library, then last year thought I might replace my (Windows) laptop by adding a keyboard and mouse to the iPad so I wouldn’t have to take both into the field for minor work. I’ve also got a Samsung S7 so I tested it out as well. The capability/usability gap between the full desktop version of Word and the mobile versions made me give up. Understand I have a dozen templates, from simple to complex, in Word, and around 20 calculation or tracking Excel sheets - so transitioning to Pages/Docs and Sheets/Numbers would cost me about $20k in productivity time. And I still wouldn’t have my CAD, finite element analysis, or industry-specific utilities with me.



  • 100% true - but if people feel the need to create so many mods, then there are probably lots of things people feel aren’t good enough about the game. I’ll admit my gaming time is limited, so just researching and adding mods could easily take all my time. I mean, fuck, I sold my Warthog HOTAS and went back to a cheap thrusmaster not because I liked the thrustmaster better, but because I was spending more time writing and fixing scripts and updating my bindings than actually playing the game. And every time an update would come out that would break a script I would spend pretty much my entire gaming time budget for a couple weeks just getting it running again. It got to the point where I just didn’t play those games because every patch would change something and something (even something small) would break or be incompatible. I’m kind of over that.





  • If you’re not writing your own software for the phone, and you don’t need access to the raw sensor data, there’s likely an equal app for iPhone now. I was in the same boat for a while - needing things that only android offered. I switched to iPhone in '19 I think, and I’ve found replacement apps for everything except detailed wifi scanning. Also, the apps I used on android which offered direct GPS tracking would show how many satellites and nominal locations are just binary - you have signal or you don’t. That’s frustrating when you’re at the edge of signal and trying to get a lock.

    I can see how it would be a deal breaker if you need a specific app for work. I can’t switch to mac as several of my (multi-thousand dollar) analysis programs are windows only, and if an update breaks something or there’s an incompatibility, it costs me $2k/day to troubleshoot.


  • 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.
