I also stopped arguing, I don't waste energy or my focus on random stuff, did happen with the age I think... unless... unless it's my wife or my mum who is wrong. If I think I'm right and they wrong, I will argue with al my energy. Of course!

I never did choose any single thing in my job, just because of how it could look in my resume.

After +20 years of Linux sysadmin/devops, and because a spinal disc herniation last year, now I'm looking for a job.

99% of job offers, will ask for EKS/Kubernetes now.

It's like the VMware of the years 200[1-9], or like the "Cloud" of the years 201[1-9].

I've always specialized in physical datacenters and servers, being it on-premises, colocation, embedded, etc... so I'm out of the market now, at least in Spain (which always goes like 8 years behind the market).

You can try to avoid it, and it's nice when you save thousands of operational/performance/security/etc issues and dollars to your company across the years, and you look like a guru that goes ahead of industry issue to your boss eyes, but, it will make finding a job... 99% harder.

It doesn't matter if you demonstrate the highest level on Linux, scripting, ansible, networking, security, hardware, performance tuning, high availability, all kind of balancers, switching, routing, firewalls, encryption, backups, monitoring, log management, compliance, architecture, isolation, budget management, team management, provider/customer management, debugging, automation, programming full stack, and a long etc. If you say "I never worked with Kubernetes, but I learn fast", with your best sincerity at the interview, then you're automatically out of the process. No matter if you're talking with human resources, a helper of the CTO, or the CTO. You're out.

No icons in my desktop (window manager, fluxbox). It's the UI I'm used since... too many years to count.

Custom keys to launch the most used apps.

Alt+F2 to launch less used apps.

And... the big star... one of my reasons for stay in fluxbox for so many years, the custom menu (right click anywhere in the root background, left click in the corner of the toolbar, or custom key to launch the menu).

Custom menu that can make includes, oh yeah, can be updated via cron/systemd-timer/scripts, etc so you can have a hierarchical menu to all your machines, by project, by datacenter, by service, IPMI, ssh, remote desktop... always up to date (i.e. from ansible-inventory). Or you can have your browser boomarks in the menu (with the same folder hierarchy). Or you can implement your own RSS in the menu via cron. Anything you can imagine.

For me, hierarchy > 2D positioning, and "desktop" != root folder for any "data".

Last step of my weird, non mainstream setup, is the all my data is not in my home, but it's in /data/myuser (in a partition separated from the OS), in folders like backup, docs, downloads, media, src, vms which are linked to my home. All dot files that I care are under my custom config management system (sh script + git), and all the data is in /data (+backups). Why I mention this? it's on topic... some apps try hard to use the "desktop" directory. So I have this bit just for them:

    $ grep DESKTOP .config/user-dirs.dirs
    XDG_DESKTOP_DIR="$HOME/docs/desktop"

Because why the hell a browser need to mkdir ~/Desktop or ~/Downloads for nothing.

My app launching shortcuts/menu are very well organized and optimized. My data is in /data. I live without the "desktop is everything/anything/chaos-thing" seen in many people machines, and I'm happy.

When I've used other's OSs with a desktop full of icons, I dislike specially not being able to make the exact placement because of auto alignment.

If I used desktop+icons, would like something like diagramming apps: "Let me place things exactly where I want, but, let me align groups of selected items, horizontally and vertically, via context menu/shortcut when selected".

Debian can run with SELinux if you like that.

Debian uses AppArmor by default, probably because of the Canonical influence (there are more Debian developers and maintainers paid by Canonical than by RedHat).

But you can run Debian with SELinux (as well as with other LSMs, MACs, etc like Tomoyo).

At my last jobs, we disabled any of SELinux, AppArmor and Auditd on Debian/Ubuntu, just for the sake of performance. And we never detected any security issue for our usage and requirements. So I'm not an expert in this field.

Not sure what the purpose of the article, or the whole blog, is. You want to influence the choosing of Debian Vs RHEL Vs Oracle Linux in some place? As I'm not sure, will stop here.

Not sure if call it mental or physical organization, but there is more crossing out of words and whole sentences, words that I try to fit into small spaces, or arrows to/from outlined areas below with more space. Like:

    +--------------+
    |  abcd abcd a |
    | bcd abcd.--\ |
    |            | |
    |  efgh ijkl | |
    | ijkl m nnn | |
    |            | |
    |      +-------+
    |      | abc a |
    |      | abcd  |
    +------+-------+

A technique that I don't know what to call, is the horizontal brace. Like the ASCII 123, but horizontally, to insert something between two words, above or below the line.

A handicap of the notebook, is that you can't find historical data/names/dates so easy, or synonyms... but as I iterate a few times over the text after the first draft, those gaps can be fixed latter while typing the text.

Sorry, edited to clarify. I mean avoiding AI.

Mainly I use vim. But yes, sometimes I also use a traditional notepad with a soft ink pen. To avoid myself some screen time, because I'm out of home, or just to make some use of it.

I think the output flow is about the same using pen and paper than using vim, at least for me.

The original "By hand" did mean "without AI help/inspiration".

I'm writing a book. A novel. By hand (this is, no AI involved, just me and vim).

Sometimes I feel I'm loosing the time, because nowadays there is a lot of AI generated content and even more competence in self-published books.

After a long walk against myself, of about 10 months, it's nearly finished (in my native language, Spanish). It still needs a few more reviews and retouching.

I got recently unemployed after +20 years as Linux sysadmin, and my wife is now unemployed too (after +20 years in HHRR), fortunately we have still a few savings.

I dream that it will (economically) work, but most of the time I intuit there will be less than a few sales from family and friends.

Depending on how it goes, I've already the script for the second and third parts.

In parallel I'm researching different ways to generate cash flow without working for another person. I would like to avoid going to search for a job in the current market of cloud, docker and kubernetes, as I'm more a hardware/colocation guy, and 99,9% of job offers request for docker/kubernetes.

It's wrong.

    3500 in -> go to parents house -> 1000 into bitcoin
                                   ->  100 into speculative coins on bull market, or making sorts in bear markets
                                   ->  300 into gold
                                   ->  600 to stocks with dividend growth
                                   ->  400 to real state or REITs
                                   ->  200 to speculative stocks
                                   ->  500 to your bank account (with some interest)
                                   ->  200 to cash, for those days you go out of your parents home
                                   ->  200 to presents for your parents

If your parents complain, give them the money of the presents, part from the bank account or from the speculative stuff, to silence them.

Repeat and reinvest benefits into non correlative actives.

Once you reach a balance of ((90 years - your age) x 12 months) * (3500 * N), maybe you can leave your parents home (not mandatory), and try to race with your yearly benefices, against the *real* inflation. N is a magic number, to cover the compound inflation during all those years, without penalizing too much the first years.

Maybe next year 3500/month is still ok, but in 30 years it won't.

If you're over 70's, do not follow this advice, take the 3500 and live la vida loca each month. Like in the "latin" song from the country that did never ever speak "latin".

Have a nice day.

Now seriously: The real important stuff when working with budgets, is to "see" the "estimate Vs real" thing.

Reminds me of those monitoring dashboards printing lot of unexpected output from checks, which in turn doesn't expect not being able to interact with state files on a read-only filesystem, reporting the wrong state (i.e. critical instead of unknown), etc.

More fan of agents and an HA core for monitoring, than from direct push notifications, but still, used this smartd notifications like 15 years ago in Debian, and never realized of this issue (maybe because once the OS disc fails, we cared more about other issues than about the smartd notification).

Those were the years were you could try to put the mechanical disc in the fridge for some minutes and try again, or with some Seagate disks, change the electronic circuit for other disk of the same model and recover the data (they used to fail in the electronic part more than the magnetic plates).

If my ISP gives me 10 Gbps, I want my PC to have (at least) a 10Gbps single path to the router.

So, If I already have a 10 Gbps path to the router, I don't want to add a 300 Mbps failing air path added to my way to the router.

In the context of the parent (at home networks), I think most people has two paths... WiFi or RJ45-UTP. And with that multipath setup (WiFi + RJ45, I don't get why other comments are talking about cellular networks "at home") is not usual to walk away; right, you could walk, as far as long is the rj45 cable, but...

To keep HA on WiFi when walking around, there are other technologies more battle tested than MPTCP.

At home/lan we use LACP, VRRP... I mean link aggregation and HA needs are solved time ago.

With multiple ISPs, or on a complex enough LAN, we can use multiple routing tables + weights too.

Also, if the ISP at home can do 10Gbps, 1Gbps, 300 Mbps whatever... I want to be able to use them with a single path, so there is no gain using multiple paths. Eventually, when I have cable+wifi connected at the same time, I use to force one of both, cannot see a reason to prefer using both at the same time.

Maybe the latency thing? Never had that issue at home, but could understand that usage case "just use the network segment with less latency to reach $thing".
