my life in a nutshell: I pay $4 a month to run headscale on a tiny VPS in order to avoid the possibility that I may one day fill up all 100 slots in tailscaleā€˜s free plan

see, you send your messages to Trustworthy Chuck, and theyā€™re encrypted all the way

then he saves them in a text file in plaintext

then chuck encrypts it to send it to someone else! thatā€™s way more encryption than most e2ee messengers

also pssh with these people and their ed25519 encryption. how many bits do they even have, huh? 256? hah Iā€™m sitting here with like twice that in my RSAs

eight and a half hours of client work later and Iā€™m supposed to be able to do the things on my personal todo list, now?

how does anyone keep up with this? >.>

ktemkin,
@ktemkin@chaos.social avatar

to be fair I guess there was also an hour and a half of finance and budgeting, and an hour of open source work before that; so maybe weā€™re actually doing okay?

@whitequark we canā€™t get stims to work like they used to, anymore ā€” and the more time goes by the more our brain resists taking them

maybe we need to switch to likeā€¦ methylphenidate, for a bit, just to let the brain know whatā€™s in store for it if it doesnā€™t fall in line

(more realistically I suspect the sheer number of anticonvulsants we have to take to not be tortured by internal tremors is actually reducing the efficacy of stimulants)

ktemkin,
@ktemkin@chaos.social avatar

@whitequark there are other drugs too, but the ones we take donā€™t tend to make us more able to get stuff done; just less broken in the moments between >.>

btw, if youā€™re of the opinion that phrases like ā€œchecking if X is saneā€ / ā€œsanity checkā€ are awkward/inappropriate language to use in code/docs:

the phrase ā€œsensicalā€ or ā€œconsistentā€ often fill the gap nicely (e.g. ā€œensure the value X is sensicalā€ / ā€œconsistency checkā€)

ktemkin,

@xahteiwi "sanity check" is an English-language idiom, anyway, that carries meaning because of the culture it's steeped in, so I think it's actually a worse violator than a word that has a relevant dictionary meaning, especially in terms of being jargon

(I think I'd prefer the more complex word to the idiomatic/vernacular phrase were I reading it in one of the various languages I speak but am not a native speaker in)

ktemkin,
@ktemkin@chaos.social avatar

@xahteiwi @funkylab I mean, Iā€™m not suggesting anyone be forced to switch over ā€” I just feel like I might make other people feel bad if I use those terms, so I tend not to

on the other hand, with how much trauma I have? Iā€™ve absolutely been somewhere between ā€œgoing insaneā€ and ā€œinsaneā€, so I less need a sanity check and more a check that at least my code is consistent and my results make sense

ktemkin,
@ktemkin@chaos.social avatar

@xahteiwi @funkylab (also worth noting that ā€œsaneā€ being a positive term is actually part of the problem ā€” in the same way as using saying ā€œabledā€ or ā€œnon-handicappedā€ as a positive term would be.

even if you believe itā€™s better to be sane and able, itā€™s probably not kind to put reminders of the whole thing in your code; and may make people think youā€™d look down on them for being otherwise)

we have a problem where we lose our phone frequently while itā€™s in plain sightā€” mostly because it blends in with darker surfaces like desks or in piles of darker blankets. worse, our brain just isnā€™t able to always put it in a sensical place

we shall see if an engineering solution does better than a policy one:

@recursive @stoneymonster I worked on a Citrix project that wound up being in the hands of an much smaller company and team after Citrix divested themselves of it, and once we dug ourselves out of some of the bizarre decisions they had made, it was a massive boost in development speed

btw, in the same way you might have multiple backup hw security keys, consider varying the brands of the ones you buy, within the realm of the ones you trust!

if one manufacturerā€™s design has a fault, itā€™s better if your keys are not all impacted at once (especially if the fault is one that makes them stop working too soon, or etc)

ktemkin,
@ktemkin@chaos.social avatar

this advice brought to you by my pack rat desire to try all of the various hw key technologies

@jpm this is one of those client projects where itā€™s being made in such quantity that every layer I can strip off saves thousands per batch (and yet everything is differential and needs approximate impedance control up to some GHz)

thereā€™s three of these CSPs in close proximity, the main manufacturer only has a 1:N:1 process (so no arbitrary blind and buried vias), and I would like the planes under them to not resemble swiss cheese =P

ktemkin,
@ktemkin@chaos.social avatar

@jpm [I managed to break everything out of a CS100, CS196 and CS 144 on only three signal layers, only blind vias on 1:2, and with no buried vias, thanks to FPGAs making it easy to swap things around]

now I just need to run an EM solver and see if Iā€™m utterly fucked =P

opinion time: whatā€™s the appropriate number of hardware tokens / HSMs to have?
(smartcards, yubikeys, hard u2f tokens, pkcs11/15/piv-card, whatever term you use for your variant~)

@svc so you /donā€™t/ want to come into this unmarked panel van?

@blue_led thatā€™s a neat idea! I use SSS for other things (especially for guarding credentials/KEKs for team things that have user privacy implications, so no one or two users can just decide to snoop), but havenā€™t thought of adding redundancy via outside distribution
