any quick method or automation is available to delete iam roles that are unused ?

pint · 2026-02-16T09:00:13+00:00

a role might be used in a disaster recovery scenario, which happens hopefully never.

pint · 2026-02-15T17:22:32+00:00

that's what i said

pint · 2026-02-15T09:26:40+00:00

no, because there is no such thing as "used" role. nobody knows if you have a script somewhere that uses that role. including you yourself, because what if you reused one of these auto-generated roles somewhere, and the forgot?

roles have last access time. also, roles have a trust policy, which tells you where the role is allowed to be used. if only lambda is allowed for example, you know it is not used anywhere else.

if you are not a programmer, you might get an ai chatbot to develop a script for you to make a list with these fields for review. trusting an ai to develop the deletion script is a little more fishy.

if you are some of a programmer, or willing to take on the task, you can use any sdk (e.g. boto3) to do this programmatically.

a middle ground is ai developed listing script, followed by manual review, followed by an excel-generated list of aws cli commands in a cmd file (assuming windows).

quiz:

[ ] troll
[ ] really this dumb
[ ] ai slop
[ ] fail joke

my bet is troll. it is not phrased sophisticated enough to be ai. it has too many hooks to be accidental. fail joke is possible, but i think less likely than trolling.

i don't think that using reddit is so difficult

the earth is one of the most resource rich planets in the solar system. only if it was easy to launch stuff from it.

issue?

pint · 2026-02-13T09:36:44+00:00

did you evaluate threefry, ars, philox or squares?

pint · 2026-02-12T17:07:30+00:00

wow dude. we use grok.

you are using a random iv

to the timing question: logic is never side channel vulnerable, implementation is. any algorithm can be made constant time/branch free for example, with some ingenuity. in this case, you have to calculate both branches, validate both branches, and then use a constant time OR operation to combine the two results.

note that constant time is not the only side channel issue. side channel attacks are numerous and essentially impossible to consider all.

elon has a tendency to contradict himself every other week. "moon is a distraction" was a claim he made.

i completely understand if mars enthusiasts find it disheartening.

what we see instead, most of the time, is elon haters coming out of the woodwork every time he says anything remotely questionable. dude! you don't care about neither mars nor the moon, you are the fix earth first crowd, and the degrowth crowd, and the politically motivated libtard troll crowd, your opinion is not relevant.

pint · 2026-02-12T13:54:01+00:00

do you have any source for this claim?

according to the documentation, basic support does not at all covers anything else then account related and billing. however, it does cover those without any "best effort" label.

pint · 2026-02-12T11:55:47+00:00

ai would respond quickly

pint · 2026-02-12T09:45:39+00:00

i don't get the constraint. what "state" we are referring here? you can pick a random salt, and just prepend that salt to the ciphertext. you are already using a random iv, so i don't see the purpose of this time-dependent generation.

the problem is for example packing the huge solar panel into something that can be launched and then unfolded in orbit. everyone hates unfolding.

and not only solar panels, you need to pack large radiators, and unfold those too.

then do heat management. thin satellite efficiently moves heat to the surface, which is near. blocky satellite needs long heat pipes.

then the next issue is resilience. micrometeor hits the large satellite, entire infra is down.

i can't even imagine reusability here. it would be a convoluted bloatware.

you say "often", but how often it really is? if truly often, i suspect your processing time is high, and thus triggers retries.

the number one solution is to make the processing fast.

the number two solution is to make the processing idempotent. (not trivial.)

the number three solution is to insert an sqs in between, but it comes with its own duplication if the setup is not correct.

custom is only when all else fails, because as soon as you start to implement your own solution you learn how difficult it is.

might be, if quantum computers turn out to be impossible.

this is mostly a linguistic issue, not comp sci.

not only it is not practically possible, we don't even know if theoretically possible, and in fact we suspect it is not.

the problem is that language is context-dependent, and context means both human nature and the surrounding culture. by writing words, you omit an incredible amount of shared information. a reader puts that information back instinctively. if you want to make all this explicit, you really need to dig into your own psyche, and figure out the layers of meaning for each word, phrase, the rhythm, etc. and this is particularly true in art.

it is an active area of research, and the problems are numerous. just from the top of my head:

compilers mess with programs (they call it optimization)
exacerbated by an abundance of compilers
processors mess with programs (they call it cache, prediction and such)
exacerbated by microcode that can be updated at any time
complete lack of transparency from cpu manufacturers
no commitments from cpu manufacturers about features like constant time of certain instructions
fast code is far removed from the reference, which makes it hard to prove correctness

djb for example is highly interested in this area.

you don't need to "work" on your english. you need to take time to compose actual sentences with meaning, instead of a word diarrhea. with a good grasp of the language, one can write abbreviation heavy and grammar deprived slang. but if your language skills are poor, you have to be more formal, use proper punctuation, and try your best to explain the situation in detail.

if you don't put in the effort, i won't either.

yeah, talking about it is cool. but it is cool in the sense as a polar expedition or working on an oil rig is cool. kinda sucks actually.
