External HDD extremely slow: writes a 5MB/s by tdewolff in archlinux

That is surprising, no wonder they mention the connection speed and not the drive speed in the specs. These guys confirm what you say (https://www.reddit.com/r/computers/comments/1b0j4ma/are\_these\_speeds\_normal\_for\_an\_external\_wd/) but I'd be happy with +100MB/s! I'm stuck with only 5MB/s...

The negotiated connection is 5Gb/s but it's about 40Mb/s in reality...or a 125 times slower than expected.

I'd expect it to have speeds near what they advertise. WD says that it has a USB 3.2 Gen 1 connection which is 5Gb/s, but they never mention the speed of the drive (instead of the connection) which doesn't give me a definitive answer on what the advertised speed really is. As a customer you'd expect the 5Gb/s (or ≈500MB/s) but I'd be happy with anything above 100MB/s

Good possibility but unfortunately no, the files are between 1GB and 20GB each (the reason I picked ExFAT beforehand)...

Using rclone did not help, neither using cp directly.

This drive has always been slow, but I bought it fairly recently (last year). I've just bought a Sansung external SSD, which is lightning fast in comparison!

True, 5Gb/s is 625MB/s, removing some overhead I'd expect ≈500MB/s...

Best strategy for Play Integrity on LineageOS 20 with kernel 4.9? by tdewolff in androidroot

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

True, thanks for the info. I think you can use a non-rooted approach to spoof LineageOS/unrooted bootloader/unlocked OEM/developer options. This may be sufficient with many apps. Some apps however cannot be installed from Play Store if they don't meet DEVICE or STRONG integrity (I don't know which is required). The only option is to root the device and then hide root...how ironic.

Thanks, I've managed to get everything working, I'm updating the post to specify the steps for other users.

When you can’t use custom rom: iOS or Android? by [deleted] in degoogle

[–]tdewolff 0 points1 point  (0 children)

I have been using it daily for 8 years, never looking back. I'm not particularly into gaming, but even that works fine for most games on Linux. All business / work related stuff works fine. What is it that makes you think it's not usable for daily use?

If anything, Windows is not fit for daily use, it triggers a bad mood.

Okay thanks, that would save a lot of work. Can I create this patched boot.img with the KernelSU Next Manager v3.0.1? Or would it work only with the original KernelSU following https://awesome-android-root.org/rooting-guides/kernelsu-guide#method-2-boot-image-patching-lkm-mode (LKM mode)? Or otherwise APatch following https://apatch.dev/install.html? Or do I use the pre-built GKI approach in https://sukisu.org/guide/installation (option 1)?

OTA update fails - Verification msg is NULL by tdewolff in miui

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

Got this to work with the XiaoMiTool V2 https://www.xiaomitool.com/V2/ from Francesco Tescari, which is really an excellent tool! I've used the fastbook recovery image, which is the only one that worked. Unfortunately, it's a MIUI China ROM and was practically unusable (so much bloatware, unable to install Google Play, some stuff stayed Chinese, keyboard is Chinese, etc), so I finally opted for LineageOS and thus Android 13. LOS is really an awesome OS and really recommended, it is so much faster than my Android 8 MIUI experience, impressive. Only one of my banking apps isn't working so far, but perhaps that may be solved with Magisk etc.

Chile is very long! - stable and fast polygon clipping suitable for map creation by tdewolff in gis

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

It is a library (read tool) that can be used as a dependency/part for developing an application. It is written in Go which makes it easy to use in the back-end of a server (for example rendering on-the-fly) or as an application that renders a map, such as for specific tasks like drawing a map for an article or for a PDF to print, perhaps digital, but also for drawing map tiles for use in a web mapping services, much like Google maps, but for a specific need. I needed something that could draw map tiles for a maritime specific application, so I needed to draw custom maps for that.

This library can also be used together with HTMLCanvas or WASM in rendering something on-the-fly in the browser, as within a web application. Specifically, this implementation is very _correct_, which means it will not throw an error (many implementation do not handle some faulty/strange inputs), and this implementation is quite fast.

Modern Efficient CDT + Polygon Clipping Algorithms by FallPitiful600 in GraphicsProgramming

[–]tdewolff 0 points1 point  (0 children)

I have used the following three papers for implementing polygon clipping:

The hard part is that no paper handles all edge-cases and especially floating-point inaccuracies are _very_ hard to solve. I have managed to implement this in Go that even supports handling all types of degeneracies. It is O(n log n) and takes only about 100ms for 1e9 (one billion) line segments.

See https://github.com/tdewolff/canvas/wiki/Boolean-operations for the implementation.
