  • You might want to re-read the article. That quote was talking about lithium ion batteries.

    This scarcity, combined with the surge in demand for the lithium-ion batteries for laptops, phones and EVs, have sent prices skyrocketing, putting the needed batteries further out of reach.

    Lithium deposits are also concentrated. The “Lithium Triangle” of Chile, Argentina and Bolivia holds more than 75% of the world’s lithium supply, with other deposits in Australia, North Carolina and Nevada. This benefits some nations over others in the decarbonization needed to fight climate change.

    “Global action requires working together to access critically important materials,” Meng said.




  • If the slide has all the information, then it’s a poor slide deck.

    The slides are supposed to be an outline. The rule of thumb is max seven lines and max seven words per line.

    Here’s a couple examples.

    Good slide:

    • Revenue: -10% vs Estimate
    • Industry trends
    • Low demand for new products
    • Strong demand for XYZ

    Also good slide, depending on who you’re presenting to:

    • Revenue: -10% vs Estimate
    • Industry: -3%
    • New products: -30%
    • XYZ: +4%

    Bad slide:

    • Revenue is 10% below estimate
    • Industry has seen a 3% drop in sales
    • New products ABC and MNO have had a 30% lower demand than we expected
    • Product XYZ has higher demand than anticipated with sales 4% higher than estimate

    All the extra information on the bad slide can be delivered by the presenter. It’s not necessary on the slide. The slide is for people to glance at to assist them during and after the presentation and to help them anchor themselves in the discussion.






  • OpnSense would be the easiest way if you wanted to go. It’s still not easy, but the articles online should help you out.

    First you’d need a machine. I’ve got an m920q I bought off eBay for $135 after shipping.

    The computer will likely only have one Ethernet port. And it’s likely the port is Realtek which isn’t supported well.

    So, you’ll need to get yourself a NIC (a fancy term for a network card). There are good forum posts and articles online about the best NICs to buy for your needs. Intel is a must. However, you can find many of their NICs online labeled as another brand - usually HP, Lenovo, or Dell. Again, the forum posts will tell you what to look for.

    If you bought the same computer I mentioned above, you’ll also need a riser and a bezel. Amazon and eBay will have a good selection.

    Now assemble it. Flash the computer with OpnSense. Don’t plug it in as your router yet. Follow along with some basic setup guides online to figure out how you want it configured.

    Once you’re happy, plug it in as your router and test that it works. If not, you’ll need to put your old router back in place until you can figure out what you need to change.


  • SD has pass through charging, so once the battery is fully charged and also while it is plugged in, you aren’t powering it through the battery like cell phones and most laptops do.

    That’s how nearly all modern devices work. Li-Ion can’t be charged and discharged simultaneously. There is circuitry to split the power between the battery and the device when it’s being charged.

    Cheaper devices will just stop charging when you use them or they won’t work at all when plugged in.




  • Only way I’m using most shopping sites is if I know they’re trustworthy and if they support PayPal or one of the major payment processors. I’m not going to type my CC number into a random website and trust that they aren’t hacked.

    There are a lot of issues with PayPal, but at least it makes it easy for me to get a refund if the seller refuses. The last time I had to get a refund, it was because the seller told me I had to ship my $20 product back to China in order to get a 50% refund. This was despite the returns agreement explicitly requiring them to cover return shipping and that shipping it to China would have cost me about $150.

  • Blame the Republicans in Congress.

    It took until last May for the Senate to finally confirm the fifth Commissioner. Per law, they can’t create new rules or regulations when there’s a vacancy.

    Have you noticed that 5G was getting faster and had more coverage until it more or less stopped last year? For the first time in history, Congress did not renew the FCC’s spectrum auction authority. T-Mobile bought a lot of 2.5Ghz spectrum back in 2022 but the FCC couldn’t grant it to them. It wasn’t until a month and a half ago that they could use it… Because Congress passed a bill that granted the authority for auctions held prior to March 2023.

    They’ve also tried going after the VOIP services that don’t follow STIR/SHAKEN or allow robocallers. But they don’t have enough funding to do much more than the minimum. For the very few that they can catch, they first provide a warning period for the company to remove robocallers and correct their systems. If that fails, the FCC then permits carriers to block the provider, but they can’t mandate it.

    Except even that’s not enough. The FCC can’t take actual legal action against the providers, only the robocallers. So quite often, the provider will just change their business name, list different fake people as their executives, and then rejoin the networks as if nothing ever happened. Look up One Owl Telecom - they’ve done this numerous times.
