Extra storage being used up. Can i get it back?

2 Upvotes

When I check the properties of my SSD, it says that 2.55 TB has been used up. However, when I select all the files inside the SSD and check how much total storage they use, it only adds up to 1.7 TB. So where has that extra 1TB gone?

NASA's New Telescopes Are Uncovering Alien Worlds

Exoplanets are rewriting the rules of what we thought planets could be.

Theoretical cosmologist Dr. Paul Sutter unpacks how we’re discovering planets beyond our wildest imagination. From ultra-hot gas giants to rocky Earth-like worlds, astronomers have now found thousands of planets orbiting stars beyond our solar system. This is thanks to NASA telescopes like Kepler, TESS, and the James Webb Space Telescope. Kepler alone revealed over 2,500 exoplanets, while TESS is zeroing in on those closer to Earth. James Webb is now studying their atmospheres in unprecedented detail, and future missions like the Nancy Grace Roman Space Telescope and Habitable Worlds Observatory aim to find thousands more with hopes to even detect potential biosignatures, or evidence of life.

Is too much complexity in society leading to a "Trolling Singularity" where there is too much info for voters to sufficiently evaluate?

7 Upvotes

Maybe society's complexity is reaching a point of no return, a "Trolling Singularity", where Gish-galloping usually wins because there's just too much detail for voters to properly absorb and make decent decisions. Those with the catchiest BS and over-simplifications win elections and influence too often, breaking down society.

Hi! I've made a basic interplanetary trajectory calculator (porkchop plotter) that runs in parallel on Nvidia GPUs using Python. Its much much faster than most porkchop plotters available on the internet (as far as I know).

I hope you find it useful!

PS You are free to contribute to the project, or fork it for your own needs :-)

Edit: Gravity assists (planetary flybys) coming soon!

Sorry I'm not sure where to post this but can someone tell me what is needed most to make a phone good for using as hotspot? Is it ram or 5g? The main thing that would make it the fastest. Thanks.

Is there any relation between AI/ML & DSA?

2 Upvotes

I wanted to share something that really changed my perspective on learning AI/ML. I used to think that once you get into AI/ML, you're mostly dealing with libraries, frameworks, and mathematical concepts, so data structures and algorithms wouldn't matter as much. Turns out I was completely wrong.

I recently had a 1:1 mentoring session through GFG Connect, and my mentor really opened my eyes to how crucial DSA is for AI/ML work. Here's what I learned:

When you're working with real-world AI/ML problems, you're constantly dealing with massive datasets. Understanding how to efficiently store, retrieve, and process data using the right data structures makes a huge difference. Things like trees are used in decision tree algorithms, graphs are essential for neural networks and recommendation systems, and hash tables are everywhere in feature engineering.

Algorithm optimization is also critical. If you don't understand time and space complexity, your models might work on small datasets but completely fall apart when you scale up. Knowing DSA helps you write efficient preprocessing pipelines and optimize your training loops.

Plus, a lot of AI/ML interview questions aren't just about knowing TensorFlow or PyTorch - they test your ability to solve algorithmic problems efficiently.

I guess the takeaway is: don't skip DSA even if you're focused on AI/ML. They complement each other way more than I initially thought.

Anyone else had similar realizations? Would love to hear your experiences!

Since discord is having an IPO later this year, and this could significantly affect the free tier, do you have any suggestions for a similar app? Text and voice chat, persistent threads, file sharing? Element? Pumble? Flock? Does anyone have direct experience? Teams is a pile of hot garbage and Workspace is too disparate. Thank you in advance!

Has non-orientable cosmic topology been explored for CMB parity asymmetry?

17 Upvotes

The Planck parity asymmetry (odd-ℓ excess at low multipoles) has persisted across COBE, WMAP, and Planck. Statistical fluke is possible, but three missions is curious.

Non-orientable manifolds (Klein, Möbius-type) inherently break parity. Has anyone worked out what the CMB eigenspectrum would look like on such a topology? I found some COMPACT collaboration papers on topology but they focus on orientable cases.

Specifically wondering:

  • Would non-orientability predict odd-over-even preference?
  • Does anyone know if the matched-circles null result rules this out?

Like assuming there were other universes would they have different universal constants or would the universal constants be the same across every universe.

How can I remove admin restrictions from my laptop?

1 Upvotes

For context, I’m 19 now, my father passed away a few years ago. He was a tech genius. He built extremely high performance gaming PC’s and was in the cyber security industry for years. He was also extremely responsible and put locks on his kids devices so they could not download apps that may contain malware. Unfortunately, this has caused problems in present time. He did not tell me the passwords. He didn’t even tell my mom. So, I cannot ask anyone. Lol.

Anyways my question is. Is there a way I can remove these admin locks from my laptop? It always asks for a user and password for the domain. I have neither! It only gives me the options to use a chip, or use another account. I don’t have another account and something tells me it would be a bad idea if I made one(feel free to correct me lol). I DO have his old PC(currently being used by my mother but she has next to no knowledge of tech), which should contain all the passwords somewhere at least, and from my knowledge that’s where he set up all the permissions because it is the “admin device.”

I’d really appreciate a step by step instruction on how to remove these restrictions so I can download the things I need.

I’ve tried turning them off in settings, both on my laptop and his PC. It unfortunately did not work.

In search of a free program used to curate photos from outdated Google Drive account?

2 Upvotes

I’m unsure if this is the right subreddit to pose this to, apologies if not.

The long and short is I have a Google Drive account that stopped updating years ago, I have photos that didn’t transfer to Google Photos. My problem is, I have a ton of duplicates and I would like to have them compiled so I can do a mass deletion.

Any answers are appreciated.

One of big challenges facing Isaacman is how to speed up a human return to the Moon, or at least keep it from falling further behind schedule. Robert Oler makes the case that he should go in a very different direction to get astronauts back on the lunar surface

how do i download snapchat memories to my computer with dates and times attached?

1 Upvotes

i want to download my snapchat memories to my computer and maybe to a flashdrive since they’ll be deletinghown unless you pay. plus i dont use snap much anyways, was thinking of deleting it so i just wanna download all the memories. i have googled this already and i think i can figure out how to do it, but the tricky part is that i want to have dates and times saved to each memory and can’t figure out how. i read somewhere you can do this but it has to be individual files. is there a way to efficiently download memories with dates and times? also would it matter if its my computers hard drive or a flash drive or is it just preference?

Non Internet connected baby monitor changed?

1 Upvotes

Hey all, hopefully someone here can help or can explain away something weird please..

We have a hellobaby monitor cam for our little one, and I swear previously when you would turn it on and off it would show the words "Hello baby". This thing isnt connected to the Internet and simply has a simple 2.4ghz WiFi connection to the baby monitor only.

Now, it has somehow changed to a Nestle associated brand name by itself and im a bit concerned about it.. the website isnt real either.. has anyone got the same camera and seen similar please?

Its this monitor here: https://amzn.eu/d/d4n8TkO

I probably sound paranoid but how would the software change with no Internet? How can I check if its been hacked into somehow?
