  • They are amazing but at the end of the day they are still humans and they can make mistakes. In the YouTube video referenced one of the C devs is heavily against rust.

    Decided to go look for CVEs from code the guy manages (Ted Ts’o) I found these

    CVE-2024-42304 — crash from undocumented function parameter invariants

    CVE-2024-40955 — out of bounds read

    CVE-2024-0775 — use-after-free

    CVE-2023-2513 — use-after-free

    CVE-2023-1252 — use-after-free

    CVE-2022-1184 — use-after-free

    CVE-2020-14314 — out of bounds read

    CVE-2019-19447 — use-after-free

    CVE-2018-10879 — use-after-free

    CVE-2018-10878 — out of bounds write

    CVE-2018-10881 — out of bounds read

    CVE-2015-8324 — null pointer dereference

    CVE-2014-8086 — race condition

    CVE-2011-2493 — call function pointer in uninitialized struct

    CVE-2009-0748 — null pointer dereference

    Do you see a pattern in the type of error here? It’s pretty much entirely memory related and right in the wheelhouse of something rust would just outright not allow short of just slapping everything into unsafe blocks.

    The Old Guard is not perfect, and they are acting as a barrier to new talent coming in. Sometimes change is good and I’m heavily in the camp that rust one of those times. Linus seems to agree as he allowed the code into the kernel which he would never do lightly or just because it’s fomo



  • Off-grid inverters bypass a LOT of that. And i should have been more clear on no backfeed. I would never recommend backfeed tbh. It comes with insane amounts of red tape, as you’ve noted, the equipment is also much more expensive for grid tie.

    Off-grid inverters are basically a backup UPS on steroids. They accept grid as an input but don’t feed back to it. They have far less regulation on their installations. Some places indeed you will still have some but usually you can get away with just having the final install inspected by a master electrician.


  • If you do it yourself it can be so much cheaper, For example with a goal of about 20k spent This bundle gets you 12Kw of inverter output and 30Kwh of batteries for 11k. Then just grab two Of these solar panel pallets for 28Kw of panels. Or Alternatively go smaller with just one pallet and save a bit. Then ofc you will get the 30% federal tax credit on top of everything

    Not everybody is going to want to do it themselves I get that, it’s actually very easy and straightforward I posted another comment here up above that goes into more detail but honestly just about anyone could learn to do it it’s not advanced electrical work by any stretch of the imagination.


  • To be fair this is just if you pay professionals to do it. They charge astronomically out the ass for labor for no reason. The actual cost of the equipment is surprisingly little if you buy it yourself, and installing it is very straightforward and easy you do not need to be particularly intelligent or skilled. I’ve done about five different systems at this point, two on RVs and three on houses. One of the houses and one of the RVs was my own and the rest are friends that I have helped set it up.

    For example with a goal of about 20k spent This bundle gets you 12Kw of inverter output and 30Kwh of batteries for 11k. Then just grab two Of these solar panel pallets for 28Kw of panels. Or Alternatively go smaller with just one pallet and save a bit. Then ofc you will get the 30% federal tax credit on top of everything.

    Ask any installer for a similar sized system and it’s almost certainly going to be 80k+ at minimum. The only part you may definitely want a professional for is if you plan on roof mounting them, have a roofer come help install the framing so you can ensure no leaks. But for ground mount (or if you are familiar with roofing) even that’s not needed.

    The actual electrical works is very straight forward. Everything is very clearly labeled, the documentation is very explicit about what goes where. On the solar panel side you’re literally working with DC so you’re literally only dealing with positive and negative. Even on the AC coupling side when you’re talking about an off-grid inverter you’re not back feeding into the grid so it’s very straightforward. Your house grid goes into the input, and your output on the inverter goes to your panel.

    The only stuff to watch out for in the NEC is rules about where your secondary panel for the solar output can be placed, has to be a certain distance from the ground, has to have a certain amount of clearance around it on all sides, has to be accessible, stuff like that but it’s all fairly easy to just look up thankfully




  • Your not too dumb to learn linux. I know it seems scary, and a lot of the autistic people that like it will try to convince you it’s only for really smart people. But at the end of the day a lot of basic tasks are actually easier on linux. There are some that are harder gaming used to be very difficult for example. Although thanks to valve, and the steam deck for the most part if it’s a steam game you can just click play and it’s probably going to work.

    But as an example of a more basic thing, let’s say you want to install an application.

    Windows: go to Google, type app name, make sure it’s the real actual website officially for that app and not a sponsored result or some other fake website, find the download, pray it’s not buried in a bunch of fake download buttons, double click the exe, be careful to make sure it’s not installing any toolbars or other packaged bullshit, finally get your application.

    Linux: there are some variations (apt dnf pacman) but all of them work the same, for arch it’s “pacman -Syu <name of app>” id argue thats WAY easier. If it’s not in the main repos chances are high it’s in the AUR (arch user repository) so you just yay -Syu <name of app>. It’s not harder (imo) just different.

    I’ve actually had a number of pretty average computer user friends let me help them transition to Linux because of the crap Windows is doing lately. And after getting used to the differences they agree that Linux is not actually harder, it’s just different, they grew up with windows, they are used to how things are done on windows, so it seemed difficult just because it wasn’t the same. But once they got used to it they would actually agree that a lot of things are actually easier.

    Now whether or not you want to put in that time to learn those differences, and change how you use your computer, is an entirely different question that you have to ask yourself. But you are not too stupid to learn Linux because realistically it’s not any more difficult than Windows is

    If we didn’t already have the perfect option that is bitwarden I would probably go for this. But there’s really no reason to switch away from bitwarden to this. It’s open source, gets regularly publicly audited, and nothing ever leaves your device unencrypted. So even if they had their data center broken into and all machines stolen physically I wouldn’t have to worry about my passwords

    I mean I was with you in the first half, I also tell my family either to use it I’m used to or don’t ask me for help. But I would not be so rude as to put gnome on it and force them to learn a completely different workflow.

    Especially when 99.9% of what they do is in a web browser there’s no reason to change anything on them. I just used KDE plasma as it’s already extremely Windows 7 like in layout right out of the box couple more tweaks to make it a little more Windows 10 like and they don’t have to relearn a bunch of shit.

    They don’t need to know how to install things, I have a tray applet helper for handling updates all they have to do is Click yes, doesn’t matter if they understand the differences between Windows and that. They just need to be able to open the web browser, open libreoffice, and occasionally click print. There’s no reason for me to force them into an entirely different workflow.

    I’m glad that your mother figured it out and seems to be doing well, but to me it just feels like an unnecessary change
