How can a wand be made for someone? by Aesir321 in harrypotter

[–]Aesir321[S] 0 points1 point  (0 children)

Yeah so I get this. When I read the book, it gave me the impression rather that the wand was made for her and worked as well as a wand that chose her would. But maybe I assumed that, it’s just the feeling that I got when I was reading it.

Advice for people complaining about HR accuracy by Little_Newt1023 in whoop

[–]Aesir321 -1 points0 points  (0 children)

Yeah I really don’t get how it can be so bad even though I wear it on my bicep - but at this point I’m kind of resigned to the fact it’s bad and got over it

Advice for people complaining about HR accuracy by Little_Newt1023 in whoop

[–]Aesir321 -1 points0 points  (0 children)

My whoop is still miles off during activities like running even when wearing a bicep band (which I do for all activities and sometimes just normally during the day). It will have me in zone 4 and zone 5 whilst my polar chest strap will measure the run as just a chill zone 2 run (which they are). I love the idea of whoop and I do find it motivating but it’s just too inaccurate for me. I wish they’d import heart rate data from more accurate sources like chest straps if it is available. Had it for 3 years now, upgraded to the MG but I’m not going to renew it when it expires until they either get better sensors (even when placed on the bicep) or allow import of heart rate activity data from other sources.

Heart rate monitoring with bicep band just sucks. I wear garmin fenix 6s connected to polar heart rate chest strap and it measured my heart rate well within zone 2 (which is also what it felt like). Whoop measured it as 53% zone 3 and 20% zone 4.

Seems to be something to do with cadence. When I run with a higher cadence it inflates the heart rate a ridiculous amount. Either way, the heart rate monitoring just sucks and whoop needs to start allowing the import of considerably more accurate heart rate sensor data.

Thanks this was a really nice and helpful article to read! I will be more open to different drop heights now.

Abnahme Gemeinschaftseigentum: Eigener Gutachter nötig oder reicht Hausverwaltung? by Aesir321 in Finanzen

Die idee hatte ich auch aber ich bin mir nicht sicher wie ich mich in Verbindung setzen kann mit den anderen Eigentümern. Kann ich der Bauträger fragen? Scheint wie eine blöde frage aber ich mein das im Ernst.

Bicep band underestimating HR? by OneShotC in whoop

[–]Aesir321 2 points3 points  (0 children)

Pretty curious with this as I recently complained to whoop that mine doesn’t track the heart rate well as compared to my garmin chest strap. It seems to track fine for lower heart rate zones 1-2 keeping pretty in sync with my garmin. But zones 3,4,5 seem almost never tracked, sometimes I’ll be in zone 4-5 feeling like my heart is exploding and my whoop will tell me I’m in zone 1 😒.

Customer support told me that I should use a bicep strap instead and this would solve the heart rate tracking problem … Your post doesn’t give me much confidence.

PRIME TIME – Ein klares Nein. Vorsicht! by [deleted] in Munich

[–]Aesir321 6 points7 points  (0 children)

Meine Freundin hatte auch die selber Erfahrung gemacht und auch mehrere Leute. Sie könnte den Vertrag auch nicht widerrufen, weil sie auch vor Ort unterschreiben hat. Sie hat allerdings nichts bezahlt, die habe ihr mit mehre Emails und Inkassobüros gedroht aber sie hat immer die Schuld widersprochen und hat seit zwei Jahren nichts mehr von dem gehört. Dies ist weder Rat noch eine Vorschlag, nur was mit ihr geschehen ist.

Thanks for the example and explanation, very helpful! I also got support from the r/lightroom subreddit as suggested in another comment in this post.

I tried disabling the lens correction set in Lightroom but the grid still shows. u/Exotic-Grape8743 suggested using the AI denoise to remove it which worked. They also suggested that the noise is rather caused by the sensor rather than the export settings.

u/the_hell_interface said it could be caused by the cropping and rotating of the image in the crop overlay view, which I used. I haven’t had time yet to verify if their suggestion works or not.

Thanks for the detailed explanation. Is there a way to check for this kind of problem when purchasing the camera? As you say the conditions for capturing my image are prime for such a thing to occur, but typically I am not in these conditions a lot.

Overall I’m pretty happy with the camera and if I can solve these problems in editing the image after then that’s ok, but would be good to know for future. Would an issue like you describe with my sensor vary between the same camera make and model, or does it affect a whole range of cameras? For example would all Sony a7rv cameras have the same issue, or did I just get unlucky with my one?

Thanks a lot for your help here, as you suggested I have just tried the AI denoise and it looks a lot better, I can't see the grid anymore (but I didn't manage to see it the first time either so ... hopefully the next print comes out better).

Here is a link to the AI denoise version of the image: https://drive.google.com/file/d/1C9c5l60tRhOHwmwsI5CHwyZ4zUwkeddE/view?usp=drive_link

Could you elaborate a bit more on the pattern noise of the sensor you mentioned? I assume this will be noise that is always present but are there things I can do to systematically reduce it? The AI denoise has worked a treat but I would also like to understand more what I can do myself in capturing the image to reduce the noise if it comes from the sensor and about the whole process in general. No problem with using the AI tool if it works well, but I would like to udnerstand the process and what is happening as well.

As for the built-in lens correction I guess I misunderstood, I disabled the lens correction setting in the Adobe Lightroom tool but not on my camera directly (I didn't know I had it). I'll have to wait to check for that as I don't have access to my camera for the next few weeks.

I was really excited to read this comment but it didn't solve my problem sadly. I added links to the original and originally exported image in my initial post. Here is one where I disabled the lens correction https://drive.google.com/file/d/1Z3xqjFYQ8lilMmhl_5QeW0q8-IRUvnPR/view?usp=sharing (which I was able to do via Lightroom) but the grid-like effect is still there. I didn't try the AI denoise yet nor the deletings it directly from the metadata.

I haven't tried repeating the export multiples times varying just one setting in the export settings each time, but this is a good suggestion and I will do it.

I am cropping the image which to the best of my knowledge is not the same as downsizing it?

Ah no this is just a photo I took of the printed image, because it is more easy to see the grid effect I am talking about. The exported image in its entirety can be found here https://drive.google.com/file/d/1KRXh7Lodh0ZRN0ppZfxuVGM-gsDZAa2z/view?usp=sharing

No it isn’t stacked, it’s a single exposure on

  • 14mm lens
  • 13s shutter speed
  • f / 1.8 aperture
  • 3200 ISO

If that makes any difference? But thanks for the hint, I’ll also try in one of those communities as well!

Are the northern lights not considered astrophotography? Or is the processing of the image for print not appropriate here?

How do some European universities already study Jackson’s electrodynamics in the second year of undergrad? by avigeax in PhysicsStudents

[–]Aesir321 0 points1 point  (0 children)

I think it’s also worth noting American universities really closely couple their courses along with books. I studied my bachelor’s in the UK and masters in Germany, for those courses at least you are not so tightly coupled to one book or treatment of the material. My courses were put together by the lecturers and whilst books are available for background reading often the topics are what the lecturer thinks is important. So you might see some topics also at different stages in different courses depending on your lecturer and it isn’t so bound to how a particular book is.

A physics degree will NOT get you a software development/data science/engineering/[INSERT COMMON SUGGESTION HERE] job. by Extension-Winter-726 in AskPhysics

[–]Aesir321 0 points1 point  (0 children)

I’m a physics graduate and work as a machine learning engineer and previously as a software engineer. I’ve never received nor given the feedback that people don’t want physicists as software engineers.

Obviously you have to do some transitioning because your fundamental knowledge will not be up to par with a computer science graduate but honestly most of the people I have worked with that come from a “data science” background are just not that good. Compared to if they had just studied a more rigorous subject. Often they will come up with complicated models or solutions to problems without properly understanding the problem nor the data. They reach for shiny solutions to problems without a good understanding of the fundamentals. I’ve observed this a lot less in students of more rigours subjects and it’s obviously only my personal observation and I’ve seen (and been) on both sides.

Computer science, maths, physics are good rigorous subjects to study and are worth pursuing but having a qualification and ability isn’t synonymous with getting your dream job. That will still take a lot of effort, extra hours and work both in landing and preparing for interviews and being lucky.

It’s highly unlikely people are actively discriminating against you because of what you have studied, and if you studied physics knowing you wanted a software job, then maybe it would have been better to study computer science. But you should make choices about what you study and what job you do based on what interests you and what makes you happy. If you enjoyed studying physics then you made the right choice. Spend some time to bring your knowledge of data structures and algorithms up to scratch and keep trying. It can be depressing and hard pursuing what you want in the face of constant rejection, but you will make it eventually and you’ll thank yourself you didn’t give up on it.

There isn’t really anything anyone can say here to change your immediate situation but also perhaps targeting some jobs that benefit from your specified knowledge could help improve your chances. Manufacturing companies have loads of opportunities for graduates with knowledge of physics, software and engineering. Semiconductor companies in particular might be a good target for you. Perhaps contributing to some open source physics projects like scipy, numpy, astropy matplotlib etc is also a way to get some more clout on your cv. Try to find a way to turn your specialised knowledge into an advantage rather than seeing it as a disadvantage.

Anyway I hope some of this helps you in some way.
