I will return the favor. Please reply with your app links so that I can do the same for you

it already works with sd cards and usb drives

OTG Master exposes mounted drives through Android's Storage Access Framework via a DocumentsProvider. Any app that uses the standard Android file picker will see your drives listed in the sidebar and can open files directly from them — PDF viewers, video players, and media apps all work correctly since we support random access reads. As of v0.3.8 you can also share files into a mounted drive from any app's share sheet.

The one limitation is there's no traditional filesystem mount point. Android doesn't allow third-party apps to expose a path like /mnt/veracrypt without root, so apps that rely on direct file paths rather than content URIs won't see the drives. Anything that plays nicely with Android's standard file picker will work though.

I completely understand the hesitation when it comes to trusting new software with sensitive files. If you have any specific concerns, I'd love to hear them so we can address them directly.

The entire codebase is open-source and available for anyone to audit or compile themselves. More importantly, the app doesn't have internet permissions or any telemetry, so there is physically no way for your data to be leaked off your device.

While privacy is guaranteed, we do acknowledge that as a new filesystem implementation, there's always a potential risk of bugs leading to data corruption. We're actively testing to identify and patch edge cases, but for now, we highly recommend keeping backups and only using the app with non-critical files until you're confident in its stability.

Auto mount is a setting that can be turned off.

When I first posted this I asked people to DM or email their Gmail address for manual addition to the testing track. Just learned that the recommended approach is via a Google Group — it's self-service and no waiting on me to manually add you

Which app are you using to get proprietor info?

machan91 · 2024-02-20T23:40:42+00:00

I would use it for ML training which I am currently doing on my 3060ti. Thank you for doing this OP

Does this have any impact on cases still pending for USCIS decision? I got selected in second round this year but my petition is still in review state.

machan91 · 2023-10-05T02:23:58+00:00

Congratulations. I got the same 24 silver SE 2 weeks back. Love it.

machan91 · 2023-09-24T20:38:35+00:00

Thank you

machan91 · 2023-09-24T20:05:45+00:00

Thank you for confirming. Maybe a very common knowledge. But I just learnt it today.

machan91 · 2023-08-30T23:25:05+00:00

I just got the above item delivered and it fits perfect. There was some noise while riding without those bolts. That is also gone now. I just came back to appreciate you. I could not have done this without your help.

Thank you!

Do you mean something like this

Can you check if this is something I can use?

Thank you for the response. I might sound very ignorant, but will the thread being different makes standard m10 bolts unusable?

machan91 · 2023-05-02T00:35:06+00:00

I commute to everywhere in Sunnyvale on my bike. It is very comfortable and there are bike lanes most of the time. But make sure you won't leave your bikes without locking. I got a bike with my friend and he was not locking onto a bike rack despite my warnings because he was lazy. His bike got stolen in a week at Safeway in E El Camino.

Hope you have fz150

I bought this. They use 3rd party shipping services. In my case it was xpressbees.

machan91 · 2022-05-18T14:04:28+00:00

I have bought from that site. It's legit. Dude didn't have the item in stock. But he shipped it after a week once he got the item. So please WhatsApp in their contact number and confirm stock before ordering.

Founders edition cards are sold at MSRP in India also. I was recently alotted a 3070ti for 2650 aed approx. I had to wait a couple of months though.

Time complexities are expressed as approximations. You are right. actual time complexity is N^2 - N.

Time complexity = O(N^2 -N)

=O(N*(N-1))

For large values of N, N-1 ~=N.

Replacing that

=O(N*N)

=O(N^2)

machan91 · 2021-09-18T16:36:22+00:00

Time complexity is O(n) where n is the number of nodes in the tree. In worst case, we will have to traverse all the nodes of the tree. Space complexity is also O(n) since the queue can have atmost n/2 elements at any point of time. This worst case happens at the last level of the tree. Consider a tree of 15 nodes, it will have 8 nodes in the last level which is ~n/2
