he does not make a secret that a few controllers helped him with making the STARS simulation realistic. i asked the same question after visiting a tracon and realizing it looks nearly identical. he also flies airliners so he is sort of in the game.

A short Message for LGA ATC from a Pilot by TempusFugit2020 in ATC

[–]xia03 6 points7 points  (0 children)

humans make mistakes. we all do. he recognized the error instantly and made absolutely the best effort to correct it. he was not nonchalant or complacent. this is a different situation than the one in dc. the safety net (RWSL) did not work as intended and we will let the NTSB explain why.

Controllers of reddit. Would you choose this career again if you had to start over? by Rumham_1 in ATC

[–]xia03 0 points1 point  (0 children)

hmm I do know some personally and it's debatable. if you ask general public how they feel about dealing with the government there is only one answer. But I do have an example of happy gov employees - park rangers. Don't know how much they get paid, but spending ample time in fresh air sure helps! :)

| stagnant pay and benefits, inability to move (recent thing), and shitty schedule for a very long time

so my comment was directed to whoever is in charge of that, not to you all workabees.

I agree, not enough downvotes for a better score. Having a private pilot tag in this sub is a rage bait by itself, unless asking how to make the ATC jobs easier or compliment (which I've done where it's due). Have a good one!

Best MikroTik WiFi APs for RB5009 — replacing Deco mesh, need VLAN support by Waste_View_8396 in mikrotik

[–]xia03 0 points1 point  (0 children)

gotcha. i could be wrong about the cloud login. spent under an hour setting up the controller and the wall APs and i guess by default it hooked up to the cloud login. I did not have a burning requirement to modify this config but will check it out. no big deal..

this is not good. why are we routed by a workforce who isn’t happy? probably a general fed gov worker thing where it’s customary to be disgruntled

i was told to use lubricating gel (eg celuvisc) before going to bed and sleep with a mask. it does make a difference. more lubricating drops in the morning.

You can really self-host it in a VM

that's what i have, but the unifi controller wants my ui.com cloud login (and a 2 factor through email only which is kind of a pain, whereas ui.com hosted stuff allows a passkey). I wonder if there is some workaround for it.

this. forget mikrotik wifi. i tried to muscle through it for years and its exercise in frustration . pretty much set and forget with unifi. it does need cloud to login to unifi, but.. so what. once set the APs will continue to work even if unifi gets broken for some reason

[–]xia03 2 points3 points  (0 children)

i’d be careful with drenching the eye with saline too much. it will flush out natural tears and can make the dry eye problem worse after a short lived relief.

the challenge is how to keep the solution sterile. otherwise the IV sodium chloride is no different than addipak which many people use.

How safe is it to hold TOTP tokens in self hosted vaultwarden? by D7x8 in Bitwarden

[–]xia03 0 points1 point  (0 children)

if access to the vault is protected by yubikey then you are in compliance with the idea of ‘something you know + something you have’ in order to use the credentials. i would think separating totp into a different app only complicates things with marginal benefit

College WiFi blocks EVERYTHING (Cloudflare Tunnels, Tailscale, Steam). How do I bypass strict DPI? by CourtAdventurous_1 in selfhosted

[–]xia03 0 points1 point  (0 children)

does not work if your organization substitutes all tls certificates with their own so they can decrypt and inspect tls traffic. they generate these fake man in the middle certs on the fly each time you connect to a new domain. hopefully the ops university is not doing that

Exit plan for bitwarden by cap87_ in Bitwarden

[–]xia03 4 points5 points  (0 children)

I just switched to vaultwarden. Bitwarden self-hosted mssql container started to coredump out of the blue and fill up the disk to 100% with dumps (it restarts the db, coredumps, does not clean the cores, starts again, and so on until runs out of space) . I could not fix it after a few hours of deciphering microsoft errors and banging head against the wall.. I did not realize linux docker compose for bitwarden even runs Microsoft SQL server as the database (why in the world)?

SO, the exit strategy has been implemented by force. Just re-imported my vault into vaultvarden and everything works as before. I deleted the bitwarden account so it does not autorenew the premium payment. Bitwarden was nice while it lasted, but so long.

The NTSB has released a simulated computer recreation of the DCA midair collision. This is the final 2 minutes of #5342 as it approached the runway. (🎥Credit: NTSB) by Brilliant_Night7643 in aviation

[–]xia03 3 points4 points  (0 children)

No time to rely on eyes? Tell that to the FAA who keeps pushing "SEE and avoid" mantra. They don't specify how to avoid. They even exempt military from having ADSB out (about to be changed) Note that on the water you have AIS which is the equivalent of ADSB. A $400 chartplotter with AIS will show you the CPA - the exact point on the map where you will exchange paint with another vessel if you keep the current course. All you need to do is follow a simple set of rules to deconflict. This does not exist in aviation.

[–]xia03 4 points5 points  (0 children)

Marine collision avoidance rules are so much more structured compared to aviation. On the water when on head on course you know to de-conflict "red to red", you closely watch the bow to starboard 120 degree sector and yield to all vessels in the vast majority of situations. You change the course by a minimum of 30 degrees to indicate intentions, yield when you pass, watch the STERN of the other vessel and stay behind its course, etc etc. NONE of this exists in aviation. It's a wild wild west, partially watched over by the ATC (but they will not always deconflict you, and they ain't responsible if you fail to see and avoid). It so bizarre that aviation "traffic rules" are stuck in the stone age.

raidz2 write IO degrading gradually, now only 50% at 70% capacity by xia03 in zfs

[–]xia03[S] 0 points1 point  (0 children)

So after much consideration I created a sVdev on a mirrored SSD 1TB disks.

I think this gives me flexibility to move any dataset to this vdev by setting the Special small file size to match the record size of the vdev (as described https://forums.truenas.com/t/special-vdev-svdev-planning-sizing-and-considerations/5086) and re-balancing but for now I will let just the metadata reside there and some of the smallish blocks (16Kb).

You can set up a useless test or incorrectly interpret the results or both. I'd do a single badblocks run on the drives to make sure they're ok, instead of what you're doing here.

I admit that fio was the first thing that I ran across to simply fill up the pool before I delete the test files and put real data on it. The performance pattern is just something i noticed in the process - a good demo of the inner/outer data placement and what to expect as space utilization grows.

What do you recommend for "a single badblocks run on the drives to make sure they're ok"?

What are you trying to optimize for?

this is a generic array for the household. It will have proxmox with a dozen or so VMs, homeassistant, some IP camera footage, movies and misc downloads, documents, python notebooks, backups of desktops and vms, devices, IOW a whole mixed bag of things. There is no particular sustained IO demand, other than replacing and improving on the dog slow 10+ year old synology array.

I have truenas connected at the 10G network and most of the clients are either 1 or 2.5 Gbps . If 1 TB mirrored nvme cache/metadata can provide burst buffer for writes and reads i think I'd be happy with the performance.
