I have a friend who, no matter how many times I have explained it, calls her Internet connection WiFi. I was really confused at first when she said she pays for Wi-Fi. She's 27.
And they used to say kids were good with computers. I think if you graph computer illiteracy vs. year of birth, people who were born around the 80's are in the bottom of a bathtub curve.
The boomers are hopeless with tech, because they grew up without it. But gen-z is also hopeless, because they grew up with opaque appliances like Iphones. You use it how Apple allows you to. The inner workings of it are hidden behind endless abstractions and shiny (liquid!) UI. Every error message is something like "Oopsie woopsie" with a sad face emoji. When it breaks you toss it in the garbage.
This reads like an "uphill both ways" story, but we used to build our own computers (still do, but I used to too), because that was how you aquired one unless you bought a Dell like a lamer. When your software messed up it segfaulted or coredumped, and you had to figure it out. When your hardware broke, you took it apart. People today use Discord because picking a client and specifying a server and port combo to connect to is too hard. And so on and so forth, you get the point...
And the point is these damn kids are on my lawn, making TikTok videos.
This also applies to many other things, such as cars. But perhaps the timeline is shifted.
But if we go earlier a bit, it was common for people to know much more about house construction, electric work, flooring, making furniture etc. IKEA emulates some of this, but it's really a different thing to live around things you truly understand, you participated in builting your house, you know how and why everything is in it, you can fix your car, you can make produce in your garden, you eat your chickens' eggs, which you can turn into baked chicken, the whole process from hatching to hen to plate is managed by you etc.
People are having less and less control and understanding of their lives. It's all "coming from somewhere" and wrapped in abstractions and euphemisms. You no longer buy things, just rent, etc. It really changes the mentality to a more child-like thinking, at the mercy of some opaque system. With AI we will get the final blow. No skills, no intellectual muscle, just as people don't even remember the and driving directions to even places they regularly visit, because GPS gives instructions so it's just not memorized. It will be the same but for everything.
It's why I became an electrician, and specialised in telecoms. I realised in my 20's that I didn't want to spend the rest of my life typing on a keyboard, and telecoms is the right kind of combination of geekery and practical work. Plus I know all the fundamental electrician stuff. I highly recommend this career path if you feel the same way. My last job was in robotics where my combined skillset of being a Linux-focused computer+networking geek and having electrical skills made me pretty unique. Lately my career has taken a bizarre turn where I do AV, networking and electrical work, plus... swimming pool maintenance. Life, uh, finds a way.
Anyways, apart from knowing how a car works on a theoretical level, I have no idea how to fix mine, and getting fucked at the dealership is a part of my life I have begrudgingly accepted.
I had similar revelation watching friend’s son asking him stuff about how to use cell phone. When I was young, it was always the other way around. And it still is, I keep helping my parents. But now I wonder if I’ll end up the IT guy in both generational directions.
I think we will, but I’m cringing harder and harder these days because my “clients” (friends and children) are often bringing me problems that are just unsolvable due to all the guardrails put up “for our protection.” For instance, “my iPhone says it’s full”
looks at storage stats
40GB worth of “System Data” and 20GB of Safari “Documents and Data” - zero visibility as to what it is let alone simple controls to get rid of it in a reasonable way. On a real computer, that’s the kind of thing an admin has ultimate authority over. Now, especially on phones, you may as well be a call center tech saying “Well, I guess you can erase the entire phone and don’t restore a backup?” because that’s the only guaranteed fix for most problems.
Not always the case. Generating traffic can be more computationally intense than routing the traffic. I've done speed tests on a few routers local to it and the results have been less than stellar compared to getting expected results with it just routing traffic (consumer routers). Granted these tests were a few years ago and things have progressed, but how often are people upgrading their routers?
Also, most 1Gbit/s and faster routers have hardware-accelerated packet forwarding, aka "flow offloading", aka "hardware NAT", where forwarded packets mostly don't touch software at all.
Some routers even have internal "CPU" port of packet core with significantly slower line rate than that of external ports'. So traffic that terminates/originates at the router is necessarily quite a bit slower, regardless of possibly extra-beefy processor, and efficient software. Not really a problem since that traffic would normally be limited to UI, software updates, ARP/NDP/DHCP, and occasional first packet of a forwarded network connection.
I guess if things get ugly they have some (terrible) plausible deniability? “What do you mean my $10 Windows Enterprise key is stolen? I thought that was the going rate. Linux is free”
Both. Microsoft would probably never go after the buyer, but I just wondered the justification people buying from the grey market are - legally speaking in many places, you're just paying money to pirate it - it's not a valid license.
I've used Ceph in a home lab setting for 9 years or so now. Since cephadm is has gotten even easier to manage even though it really was never that hard. A few pointers. No SMR drives, they have such bad performance that they can periodically drop out of the cluster. Second, no consumer SSDs/NVMe devices. You need power loss prevention on your drives. Ceph directly writes to the drive, it ignores cache, without PLP you may literally have slower performance than rust.
You also want fast networking, I just use 10Gbps. My nodes each are 6 rust and 1 NVMe drive each, 5 nodes. I colocate my MONs and MDS daemons with my OSDs, each node has 64GB of RAM and I use around 40GB.
Usage is RDB for a three node OpenStack cluster, and CephFS. I have about 424TiB between rust and NVMe raw.
I just bought a framework this past week largely due to the easy to replace keyboard. On my last two laptops a year after the three year warranty the keyboards started to die. So, just in case that happens again, and just In case fame.work were to go under, I bought a replacement keyboard from the get-go to store for later.
