  • My experience with a Pi4B has been rock solid and plenty fast for what I’ve tried so far, at low power consumption.

    While I had problems in the beginning, it was all from the micro-SD card. People here will recommend staying away but I’ve had no problems since buying an “extreme” card. Well, starting to hit the size limit now - I can no longer kick off multiple concurrent updates because limited free space available on, I think, 16G card. Get bigger


  • If you’re starting with ha, don’t feel confined to only one.

    IMPORTANT: a local area mesh is not just a low powered way of connecting devices but is inherently local-only. Highly recommended

    The more common local area meshes include

    • Zigbee - open standard, lots of inexpensive sensors
    • Z-Wave - devices need to pay for certification but are more standard. I found more smart switches using this in my area
    • Thread - the new standard. Same frequency as Zigbee but IPv6 based. Slowly rolling out.

    The new Matter/Thread standard has support of the major players (Apple, Google, Amazon) so seems like the way to go for the future, but products are slow to roll out so you can’t count on it yet

    Personally I found the strengths of each compelling so quickly added all three of the above to my ha setup. Ha is fine with it so why limit yourself

    I follow the principle that devices must work “as expected” for my users, automation adds capabilities but does not replace them. This comes together with a focus on smart switches

    • can be used interactively just like any switch
    • continue to work as expected even if ha is down
    • typically act as routers to strengthen your local area mesh. I have switches acting as routers for Zigbee, zwave, and Thread, so all my local area meshes are solid everywhere
    • then I can automate





  • I got into each mesh technology for specific devices. Home Assistant supports them all and they seem to coexist just fine in my use case.

    I have a small to medium setup with only a few simple automations and a focus on voice control and scheduling

    Preference

    • Thread - given Apple, Amazon, and Google support and the standardization work, I expect this to be the future. Eventually. But I’m getting impatient. If I’m buying a device, I prefer Thread but usually it’s not yet
    • z-Wave - my first, and most devices. Basically this was what was most available at local stores when I started. No complaints
    • Zigbee - by far the biggest selection of simple, cheap sensors. I need to more of those
    • all too much is WiFi but I try to avoid

    But it also helps that my approach is generally switches and outlets. Hard-wired, predictable network, tend to be repeaters. I have comparatively fewer leaf nodes.

    This approach also fits in with my biggest challenge. While my house is small, it’s an older one with dense materials that blocks a lot of radio signals. For example I have no cell phone reception inside yet strong signal just out any door. My focus on switches and outlets overcome this with a repeater in every room

    So for example a few years back I got a z-wave IR blaster to control a mini-split AC because at the time I mostly used z-wave. I already had a z-wave light switch in the same room, acting as a repeater, so no worries about connectivity. Now I have both z-wave and Zigbee light switches in that room so expect both meshes to be strong for any future devices in that room

    I’m not entirely sure why all the hate : Jenkins can do the most things the must ways. And yes, it’s so much nicer defining a pipeline with a fully functional language than an assortment of yaml files

    Actually that was my response when my company wanted to start using Gitlab ci. It only has one way of doing things so you can probably get a faster start if you had no ci, were a small company, and had simple builds. However we’re over 4,000 builds in many languages from 12 year old monoliths to modern micro services and containers…… and way too much godawful JavaScript. Do you want the quick and simple tool great for a small startup or the all powerful kitchen sink of tools?



  • Signing (intermediate) certs have been compromised before. That means a bad actor can issue fake certs that are validated up to your root ca certs

    While you can invalidate that signing cert, without useful and ubiquitous revocation lists, there’s nothing you can do to propagate that.

    A compromised signing certs, effectively means invalidating the ca cert, to limit the damage






  • Even from the headline, your article states they were profitable in 2020. Yes, back then a lot of it was due carbon credits. So they priced things according to the market they were in?

    Are you complaining that GM for example was only profitable because of those credits? They (and other legacy manufacturers) decided it was more profitable for them to buy carbon credits from Tesla than to develop their own EVs. You could argue they were only profitable because they could buy pollution rights from Tesla.

    But of course that’s old news. Profits ebb and flow but Tesla has more recently been profitable even not counting those credits.

    Regardless the market has changed and those pollution credits no longer exist. It’s a different world for both EV manufacturers and legacy manufacturers, so we’ll see what happens. Pollution is free again, although of course the picture is complicated by trade wars, fascism and musk s reputation, as well as the meteoric rise of competitors in China


  • Yeah there have definitely been times when I’m driving quite a bit faster than I think in my model y. But the scary part is my teen. The very first time I let him drive my Tesla, he drove faster than I ever have

    But acceleration can be worse. The first time I found a “safe” stretch of road to try, the acceleration pushed me back in my seat so far that I no longer had a solid grip on the steering wheel. I really scared myself there, and among other things keep the seat tilted farther forward now

    Still, not trying to be pedantic here but terminology is important. Seems like you’re talking about quality or reliability.

    Generally

    • safety ratings are government or independent tests on newly manufactured cars. The goal is to detect design issues. Tesla has always had very high safety ratings
    • quality or reliability is how these cars hold up over time. The goal is to detect manufacturing issues and places where too many compromises are made. There are many places attempting to do this and one source may be annual safety inspections. Teslas used to have some very well publicized quality issues that would show up here. Early model s and model X were effectively hand made, and they took a couple years to stabilize model 3 manufacturing. As far as I know they are similar to other manufacturers now (except of course the Cybertruck), but I’d certainly expect historical data to not be as forgiving.
    • accident data is real life results in how they’re used. In this case we have way too many streamers misusing teslas self-driving feature, convincing others it’s more capable than even Tesla claims, that probably contributes. But I believe it’s also the sheer acceleration. It used to be the Mustang that was stereotypically more acceleration than drivers can handle, but we may have that here as well. Every Tesla has outstanding acceleration and of course you’d try it. It will be more than you expect: can you handle it?

    Edit to add

    • insurance data generally determines repairability. We see that for a variety of reasons teslas are expensive to repair. Some of it’s the design, some the materials, some the plethora of tech, and some is availability of parts, and the lack of third party parts
