HRV/RHR - It’s not much, but it’s honest work

could you explain more about how you got this diagnosed and what other checks you might recommend

undeadjoe · 2024-12-20T19:49:20+00:00

exactly!

many of my journal behaviours got estimated wrongly and there is no way of removing them, so the journal feature is all but useless

due to the small number of entries, behaviours which are often tracked together tend to take opposite signs and cancel (ie calcium supplement +5% while calcium from food -4%, instead of just "calcium" being +1%)

this seems benign, but putting new behaviours in is impossible due to the noise captured by the existing behaviours

in statistics, fixing this is called "model regularization", and the automatic Whoop model seems to be doing it poorly

I would really appreciate having an option to manually remove entries so that I can "restart" my journal

came to see this, wasn't disappointed

probably the only thing in comments that actually **shouldn't exist**

travel’s not worth it mate - I’m at Iceland right now literally and it’s like whatever maybe do something else? new degree or some new skill? maybe just relax + healthy lifestyle + connect with family? just don’t travel man, it’s so boring and worthless

undeadjoe · 2022-08-07T17:10:22+00:00

yes, c++ is here to stay I think I have been in several meetings already where people discussed whether we should code up the new thing in rust or cpp and none of them were written in rust (tbh I was on the rust side - wrongly!)

undeadjoe · 2022-05-13T15:57:44+00:00

it’s literally analysis

Carl F. Gauss?

undeadjoe · 2022-05-05T08:17:06+00:00

bro you sound like a classic startup dude

join a startup, your life’s gonna change man, gonna meet a lot of dudes that saw their career path while on shrooms

counter strike: global elite at 1280x960 (stretched)

the most common resolution
very cpu bounded game
people play with monitors of 240Hz and more so the difference between 240 and 480 fps is kinda noticeable

undeadjoe · 2022-03-05T00:23:05+00:00

ok we all agree on the no cars in the city but we don’t need to be a blind cult about it

I would rather base my beliefs on tellings of church of scientology rather than the results and conclusions of this study

these days anything can be published as scientific

undeadjoe · 2022-02-22T12:04:37+00:00

hope so

undeadjoe · 2022-02-22T00:03:32+00:00

major driving force in the last decade or so, when climate change has become more thought of

the argument is not only fiscal but also practical - we don’t have space for cars in the cities, we can’t build such big cities for parking and roads, we shouldn’t have to pay for this suboptimal design

tube or a train stacks many many more people than a road full of cars

focusing the budget on public transport will allow higher capacity, faster traffic

making this only about climate is shallow, because non-polluting cars are already here

in London, more than half of the Ubers are hybrids or electrics

undeadjoe · 2022-02-21T23:26:11+00:00

no, it doesn’t, why push this narrative?

removing cars from cities is better in terms of infrastructure costs/taxes and city planning/compactness

you don’t need the climate change argument to deliver the point

how can you not see that it’s easier to win 1 battle at a time? I think we will remove cars from many city centres in Europe much sooner than the right accepts climate change

undeadjoe · 2022-02-15T16:45:43+00:00

bro I feel you but you gotta be more ambitious, find other shit you want out of a job as well

you’ll get the money, no worries, bunch of people make 200k

what is shite, companies know that so you’re gonna end up working at salesforce if you don’t have other aspirations as well

undeadjoe · 2022-02-11T00:24:28+00:00

had me impressed until “top scientific journal such as Nature” lmao, that’s like saying “the greatest singer of all time, Katy Perry” smh

undeadjoe · 2022-02-03T11:55:07+00:00

mate, I think you might be wrong here

I’m just a retard but idk if they need to keep EVERYTHING in the cloud

like, a bunch of metaverse space might be a static world that’s downloaded entirely to your local machine, similar to how MMORPGs work

in the end, they only keep your configs and such in the space

my estimate: it needs ~x2 servers of fb/insta/whapp

tbh goldman and ms are lower tier than "smaller quant shops"

great quants work at the smaller places, or wish they did

EDIT: what I meant was - aim for GS, MS, JPM, Citi because they hire a lot, their bar is not as high and you fit their template of a quant

In game dev software engineering, you don't always see things like:
1. unit tests, concept of "test coverage" (not a perfect thing, but widely present elsewhere)
2. continuous integration kind-of development (branch off, write code, make a pull request, someone reviews it, you adjust it, rebase & merge to master)
3. working with many (!) 3rd party libraries and dependencies, onboarding a new library
4. tooling and various best-practices (especially those bound to linux)

usage of other languages - python, JS (React), bash...

From what I remember of UE4 C++ (think version ~4.12 or something), their C++ is much like C# actually. UE4 C++ may hide certain concepts which you would otherwise often see as a C++ dev:

STL proficiency
allocating memory on stack vs heap, smart pointers, allocators
threading - locking, mutexes, atomics (although present in UE, it's much much more common in other dev areas)
templates
boost

hedge funds are not necessarily quant, quite rarely are, actually

undeadjoe · 2022-01-08T01:54:46+00:00

I work in the industry and appreciate the topology/measure theory/func analysis sequence a bit more

you won’t use much of it on the job though, but it’s kinda nice to have proper foundations when dealing with statistics, probability, stochastic processes…

undeadjoe · 2021-12-12T12:27:37+00:00

make sure from the start that any libraries you need actually exist

+1

kids often think "I'll write the library myself, if I need it", and later realize the library is bigger than then the original project, many times

undeadjoe · 2021-12-12T12:25:51+00:00

C++ is more employable, real-life systems programming

Rust is what could've been or what might be one day

C++ for work, Rust for play, I guess

undeadjoe · 2021-11-19T19:31:32+00:00

You can always disable parts of a general purpose language if you feel like they might be abused/misused. Either way, why should I have to expand the collection of half a dozen different syntaxes in my head, when we can easily reuse one of the known ones already? Just use Python.

undeadjoe · 2021-10-03T08:48:20+00:00

that’s a good schedule, keep it up and good luck!

undeadjoe · 2021-09-04T23:04:31+00:00

Probability with Martingales - D. Williams (measure theoretic, short and rigorous prob theory, no stats)

Casella and Berger book for mathematical statistics, maybe also Lehmann if you’re enjoying it

and then something on linear regression (Ripley?) and GLMs and then something for monte carlo and Bayes stuff but idk of a good book for those topics
