10:47 <beneroth> Regenaxer, Question about data modelling: You have an entity, and it has a date property. Now it's should be possible to store the date value should with varying accuracy (because of not-yet-complete or incomplete knowledge), e.g. as an exact date (2019-05-14) but also as an date-range (e.g. May 2019) - how would you model this in pilDB ? 3 properties? one bag property with 3 values (exact, start, end) ? Of course, it would be nice to have the value indexe

10:47 <beneroth> d and get with when doing a range query (when the value is within the range, be it a single value or an overlapping range value)

10:47 <beneroth> so maybe 3 properties and a +UB index?

10:51 <Regenaxer> Hmm, aren't simply 2 dates enough?

10:51 <Regenaxer> From-Till, and may be same

10:52 <Regenaxer> (if (= (: from) (: till)) ...

10:52 <Regenaxer> or just one (: dat)

10:52 <Regenaxer> and an optional diff (: rng) range

10:53 <Regenaxer> So you save space if it is exact :)

10:59 <beneroth> nice idea with the imprecision-range

11:01 <beneroth> right, probably just two (from, till) dates are enough, setting both to the same value if the exact date is known. so any range queries goes over both properties, and the results get uniqued.

11:01 <beneroth> thanks for your advice!

11:11 <Regenaxer> +UB is rather for multi-dimensional values (e.g. coordinates). IThink it will not be right for two close values)

19:56 <rick42> hallo peeps

19:58 <rick42> alexshendi: r u still using mastodon? i did for a while last year then (apparently) i've completely abandoned it. lol

19:58 <alexshendi> Hi, rick42

19:59 <rick42> hi, alexshendi!

20:00 <alexshendi> Yes, I still use Mastodon. I have deleted my Facebook and Twitter accounts.

20:05 <rick42> peter hessler was so kind enough to put up a node and so i feel bad for not using it. (guilt. lol)

20:05 <rick42> i will keep the account though. i may get back into it. heh

22:35 <beneroth> [OT] new fun with attacks on Intel CPUs (similar in principle to Meltdown and Spectre, but now targeting CPU buffers, not CPU cache!) https://mdsattacks.com/

22:35 <beneroth> "

22:35 <beneroth> We show that attackers who can run unprivileged code on machines with recent Intel CPUs - whether using shared cloud computing resources, or using JavaScript on a malicious website or advertisement - can steal data from other programs running on the same machine, across any security boundary"

22:36 <beneroth> "We show that Fallout can be used to break Kernel Address Space Layout Randomization (KASLR)," - in case we have to annoy Ubuntu eventually again (not that there is a point, but you understand, Regenaxer )

22:37 <beneroth> too many turtles
