  • I started with rootless podman when I set up All My Things, and I have never had an issue with either maintaining or running it. Most Docker instructions are transposable, except that podman doesn’t assume everything lives as dockerhub and you always have to specify the host. I’ve run into a couple of edge cases where arguments are not 1:1 and I’ve had to dig to figure out what the argument is on podman. I don’t know if I’m actually more secure, but I feel more secure, and I really like not having the docker service running as root in the background. All in all, I think my experience with rootless podman has been better than my experience with docker, but at this point, I’ve had far more experience with podman.

    Podman-compose gives me indigestion, but docker-compose didn’t exist or wasn’t yet common back when I used docker; and by the time I was setting up a homelab, I’d already settled on podman. So I just don’t use it most of the time, and wire things up by hand when necessary. Again, I don’t know whether that’s just me, or if podman-compose is more flaky than docker-compose. Podman-compose is certainly much younger and less battle-tested. So is podman but, as I said, I’ve been happy with it.

    I really like running containers as separate users without that daemon - I can’t even remember what about the daemon was causing me grief; I think it may have been the fact that it was always running and consuming resources, even when I wasn’t running a container, which isn’t a consideration for a homelab. However, I’d rather deeply know one tool than kind of know two that do the same thing, and since I run containers in several different situations, using podman everywhere allows me to exploit the intimacy I wouldn’t have if I were using docker in some places and podman in others.



  • They can’t, tho. There are two reasons for this.

    Geolocating with cell towers requires trilateration, and needs special hardware on the cell towers. Companies used to install this hardware for emergency services, but stopped doing so as soon as they legally could as it’s very expensive. Cell towers can’t do triangulation by themselves as it requires even more expensive hardware to measure angles; trilateration doesn’t work without special equipment because wave propegation delays between the cellular antenna and the computers recording the signal are big enough to utterly throw off any estimate.

    An additional factor in making trilateration (or even triangulation, in rural cases where they did sometimes install triangulation antenna arrays on the towers) is that, since the UMTS standard, cell chips work really hard to minimize their radio signal strength. They find the closest antenna and then reduce their power until they can just barely talk to the tower; and except in certain cases they only talk to one tower at a time. This means that, at any given point, only one tower is responsible for handling traffic for the phone, and for triangulation you need 3. In addition to saving battery power, it saves the cell companies money, because of traffic congestion: a single tower can only handle so much traffic, and they have to put in more antennas and computers if the mobile density gets too high.

    The reason phones can use cellular signal to improve accuracy is because each phone can do its own triangulation, although it’s still not great and can be impossible because of power attenuation (being able to see only one tower - or maybe two - at a time); this is why Google and Apple use WiFi signals to improve accuracy, and why in-phone triangulation isn’t good enough: in any sufficiently dense urban or suburban environment, the combined informal of all the WiFi routers the phone can see, and the cell towers it can hear, can be enough to give a good, accurate position without having to turn on the GPS chip, obtain a satellite fix (which may be impossible indoors) and suck down power. But this is all done inside and from the phone - this isn’t something cell carriers can do themselves most of the time. Your phone has to send its location out somewhere.

    TL;DR: Cell carriers usually can’t locate you with any real accuracy, without the help of your phone actively reporting its calculated location. This is largely because it’s very expensive for carriers to install the necessary hardware to get any accuracy of more than hundreds of meters; they are loath to spend that money, and legislation requiring them to do so no longer exists, or is no longer enforced.

    Source: me. I worked for several years in a company that made all of the expensive equipment - hardware and software - and sold it to The Big Three carriers in the US. We also paid lobbyists to ensure that there were laws requiring cell providers to be able to locate phones for emergency services. We sent a bunch of our people and equipment to NYC on 9/11 and helped locate phones. I have no doubt law enforcement also used the capability, but that was between the cops and the cell providers. I know companies stopped doing this because we owned all of the patents on the technology and ruthlessly and successfully prosecuted the only one or two competitors in the market, and yet we still were going out of business at the end as, one by one, cell companies found ways to argue out of buying, installing, and maintaining all of this equipment. In the end, the competitors we couldn’t beat were Google and Apple, and the cell phones themselves.



  • I once owned a bunch of WiFi connected devices. One day I inspected my router logs and found out that they were all making calls to a bunch of services that weren’t the vendor - things like Google, and Facebook.

    WiFi connected devices require connecting to a router; in most homes, this is going to be one that’s also connected to the internet - most people aren’t going to buy a second router just for their smart home, or set up a disconnected second LAN on their one router. And nearly all of these devices come with an app, which talks to the device through an external service (I’m looking at you, Honeywell, and you, Rainbird). This is a privacy shit-show. WiFi is a terrible option for smart home devices.

    ZigBee, well, I haven’t had any luck with it - pairing problems which are certainly just a learning curve in my part and not an issue with the protocol. I chose ZWave myself because I read about the size and range limitations of ZigBee technology, versus ZWave, but honestly I could have gone either way. Back then, there was no appreciable price difference in devices. Most hubs support both, though, and I can’t see why I wouldn’t mix them (other than I need to figure out how to get ZigBee to work).

    In any case, low-power BT, ZigBee, or Zwave are all options, whereas I will not allow more WiFi smart devices in my house. I’m stuck with Honeywell and Rainbird, for… reasons… but that’s it. I don’t need to be poking more holes in my LAN security.





  • Opening an office is a completely different thing; there is an enormous difference between offshore contractors and offshore employees. That much, I’ll agree with.

    In the US, though, it’s usually cost-driven. When offshore mandates come down, it’s always in terms of getting more people for less cost. However, in most cases, you don’t get more quality code faster by throwing more people at it. It’s very much a case of “9 women making a baby in one month.” Rarely are software problems solved with larger teams; usually, a single, highly skilled programmer will do more for a software project than 5 junior developers.

    Not an projects are the same. Sometimes what you do need is a bunch of people. But it’s by far more the exception than the rule, and yet Management (especially in companies where software isn’t the core competency) almost always assumes the opposite.

    If you performed a survey in the US, I would bet good money that in the majority of cases the decision to offshore was not made by line managers, but by someone higher in the chain who did not have a software engineering degree.


  • Thing is, outsourcing never stopped. It’s still going strong, sending jobs to whichever country is cheapest.

    India is losing out to Indonesia, to Mexico, and to S American countries.

    It’s a really stupid drive to the bottom, and you always get what you pay for. Want a good development team in Bengaluru? It might be cheaper than in the US, but not that much cheaper. Want good developers in Mexico? You can get them, but they’re not the cheapest. And when a company outsources like this, they’ve already admitted they’re willing to sacrifice quality for cost savings, and you - as a manager - won’t be getting those good, more expensive developers. You’ll be getting whoever is cheapest.

    It is among the most stupid business practices I’ve had to fight with in my long career, and one of the things I hate the most.

    Developers are not cogs. You can’t swap them out like such, and any executive who thinks you can is a fool and an incompetent idiot.
