  • Battery circuits come on enough to be a load that needs to be considered and will show up if you measure load on the device vs load consumed by the components connected to the power supply. In terms of low power devices, it is significant, though not the primary concern. But compared to the pi PSU, the charger not to mention the battery and internal PSU of a laptop, consume way more power and produce way more heat.

    All of the rest assumes needing always on, heavy load processing which isn’t what the post I replied to was talking about. I was specifically replying to idle power load. And in my case, even with a bunch of self hosted applications, most of the time my servers are idling. If I was running a virtualization farm or something that was always under heavy load, then yes, as I mentioned, a single board server isn’t ideal.

    As for disks, I don’t use SSDs on my pis except one that actually does a lot of local data processing. Everything else runs in memory and stores persistent data on my NAS, including logging. Virtual memory/swap is disabled on all and things that need temporary storage/cache of small amounts of data is cached on RAM disks where applications can’t be configured to not use disk caching. The only need for the SD card is for boot and some minimal IO needed for local OS operation. I have a Raspberry Pi 3 B i got about 8 or 9 years or so ago with the same SD card in it.

    They aren’t what I use as a database server, obviously, but they are extremely low power compared to what an old laptop would need and work great for things like pihole, and other network applications as well as being a part if my home kubernetes cluster and run the majority of the cluster’s processes on demand.



  • Not quite. Unless the system has pretty advanced power management and is using very recent technology with high density, it’s unlikely that an x64 chipset will use less power than a comparably powered arm64 chipset. Not just the processor, but the smaller board is actually a power saver and allows it to generate less heat meaning both less power wasted and dissipated as heat as well as less power needed for fans to properly dissipate the heat. I’ve never seen a laptop use 3W at idle when considering the whole device, maybe just the CPU, but not if you include the rest of the components like RAM and disks and power supply. And especially true in a laptop that is old enough that it’s being recycled. Heck, the power supply and charger alone might be using 3W at idle with full battery.

    With a raspberry pi 4, the typical power usage for the 2GB RAM model is 5W under load for the whole device and about half that for idle. Add a couple of watts for the extra memory and wider bus on the 8GB model and other things can add to that, but that’s mostly accurate. The pi 5 is a little more and the 3 is a little less. Of course, the efficiency of the laptop at full load might end up being better than a comparable number of raspberry pis it would take to do the same amount if work, but comparing a single pi or any other reputable arm-based, single board computer to a single laptop at idle is always going to be that way.







  • Problem with Manjaro is they have their own opinionated repository that is not always in sync with Arch because they try to introduce more “stability”. I found this actually caused the opposite in most cases as there are a lot of dependencies that end up being behind and so you can’t install more stable versions of a lot of software. With the complexity of modern software dependencies, it has become a big problem. Also, they have in the past caused lots of problems with AUR and have let their SSL certs expire multiple times. Overall, they just haven’t been reliable IMHO, so I moved to Fedora a while back.


  • Real problem is that the rules change every year so the software has to be constantly updated and that sometimes requires insider information about what changes are coming. Often the IRS publications aren’t available until the last minute or later, definitely not in enough time for proper quality processes. So, while simple returns can sometimes be done with software like this, a lot of people rely on the software or agencies to know all the new rules.

    That being said, I would like it a lot if there was a way to file very single form, but fill it out manually in the software, without calculations being done by the software. At least then you could file electronically regardless of what complex forms you need to file with complex worksheets and sub-forms, if the software didn’t need to know about those things, just the forms you actually file. As it is, the only way to file these is with expensive software or on paper which can take many months for the IRS to process and you could be on the hook for interest if you file something wrong and the IRS doesn’t reject in time for you to correct it and resubmit before interest charges accrue.

    Also, a lot of IRS processes require the software to be certified (or at least did the last time I looked at it) because their software isn’t sophisticated enough to validate the complex forms, so getting that certification might be difficult for FOSS software. I’ll be interested to see how that plays out.


  • Same. I had been using Ubuntu for over a decade for all of my Desktops, but had used CENTOS/Rocky for servers. Now I switched to Fedora for desktop which simplifies things since now only my Raspberry Pis use deb vs rpm.

    Snap is super frustrating and the gate-keeping of updates and features behind the Pro subscription is annoying. I don’t want to have an account if I dint have to. It’s just one more privacy violation waiting to happen with no real benefit to me even if it is free for personal use.



  • I had to get away from Ubuntu because of the recent performance issues and the requirement to have an account to get updates faster. I have used CENTOS and more recently Rocky Linux on all my servers for over a decade, so Fedora was the obvious choice for me. I had problems with desktop applications being missing from rpm repos in the past, but that has greatly reduced improved and flatpack has helped with some stragglers. But I’m still not a fan of RedHat, but Fedora is a little more separate from them than Ubuntu is from Canonical.

    I tried Debian, but it’s not easy to get up and running on a more modern laptop or desktop without a lot of tweaking and kernel mods. It’s a good base OS but not good out of the box desktop OS. Same issue with Arch based distros.
