Built a tagging small media viewer, try it out

Originally started as an experiment to test whether xattrs can serve as a viable replacement for sqlite as a container of tagging meta-data, this project has developed into a fairly serviceable small media browser and has became a tool I use to browse my vast collection of stock photos, memes, and wallpapers.

Was hoping to see what folks here thought of it. Here's its most notable aspects:

* with xattrs, tags stays with the files even if moved/renamed
* supports all popular animated image formats (gifs, webms, etc)
* will happily work with large collections containing tens of thousands of files without perf issues
* supports loading thumbnails that conform to the freedesktop thumbnailer draft standard (dbus support is WIP)
* supports mapping files to custom generated thumbnails including animated ones
* supports sorting files by numeric & delimited names
* fairly easy to customize

[This picture is from 0.0.2 so some elements has since improved](https://i.redd.it/zj6gzp7uiyu41.gif)

The long term vision for this project is to make it highly extensible (basically do for small media browsing what vscode did for programming). Also a secondary goal, via an extension, make it the UI of my other project [fs-curator](https://github.com/unreadablewxy/fs-curator).

Project Github: [https://github.com/unreadablewxy/fs-viewer/releases/tag/0.0.3](https://github.com/unreadablewxy/fs-viewer/releases/tag/0.0.3)

It also works with windows if that's important to anyone. Through some samba configs, can expose tags via alt-streams (which this program also supports).

Feedback, bug reports, feature ideas, patches all appreciated.

USB Command line voltage measurement suggestion

Can anyone suggest a way for me to have some sort of USB dongle that I can use to connect to a batter to measure the voltage and/or amperage of the battery? I want to measure my solar panel backup batteries and my current amperage consumption.

MacBook Pro 2018 / Kali Linux

Hi ! First post here.

It's been 2 days since I'm trying to dual boot kali linux on my Macintosh (MacBook Pro 2018), but it keeps failing again and again... and when I finally succeed, when I'm booting the kali partition there's this error : icm firmware is in wrong mode: 15

So I was wondering if It's me who is doing it wrong or if it's just not possible to dual boot kali on macintosh... Is anybody had similar experience ?

Thanks in advance :)

LibreOffice, KDE and Onboard

I am not sure where to post this but a while ago I had an issue under LibreOffice where I would type double characters for every button I pressed, kind of like "tthhiiss".

I recently discovered that running Onboard and LibreOffice at the same time causes the double typing to occur whereas if I ran LibreOffice without Onboard running, I can type normally. I just wanted to bring this up to anyone running LibreOffice experiencing this could examine the problem between the two programs.

I mentioned KDE because when I ran LibreOffice with the GTK3 toolkit with Onboard I wasn't experiencing double typing so it's something to do with these three all together.

A note of appreciation to everyone out their maintaining open source projects!

Earlier this week I posted a small project I was working on to reddit, expecting maybe a couple of people at most would be interested in it. To my surprise though, it gained a moderate amount of attention. Before I knew it, I was managing pull requests and helping people out with bug reports.

Before I continue, I want to clarify that I am **extremely** grateful to anyone who took time to look at my silly project, and especially to those who continue to contribute to it and make it much better than I ever would've done on my own.

That being said, the experience was weirdly stressful! Suddenly this small project for myself was no longer just for myself. I had to take into account other people's ideas for the project, various bugs that I never would've encountered during my use, in the meantime making sure the project stuck to my vision and maintained quality. Saying no to someone who has taken time out of their day in an earnest attempt to help you is no fun.

And I felt this way with only 2-3 people contributing and no more than 10 real bug reports. I can only imagine how those who are maintaining larger projects with lots of contributors feel. So I just wanted to say thanks to everyone who's putting in the work!

ASUS ZenBook Duo UX481FL & Ubuntu (X-Post with /r/ASUS & /r/Ubuntu)

Recently I bought an ASUS ZenBook Duo UX481FL, and I thought I'd share my experience single-booting Ubuntu 20.04 LTS ("Focal Fossa")... There's a *lot* of folks talking about the various versions of the ASUS ZenBook *Pro* Duo - which I'd *love* to get (I can't justify spending AU$5,000+ / US$3,196+ on a laptop though!), but not many people talking about the "poor man's" version, the ZenBook Duo.

​

Firstly, I needed to disable "Intel RST Premium with Intel Optane System Acceleration" - the Ubuntu installer simply *refused* to continue until this was *disabled*... I don't know too much about it, but it *appears* to be some sort of functionality that treats the storage drive like a RAID setup - which seems illogical, because there's only the *one* storage drive in this *particular* laptop.

Anyway with the laptop off, hold "F2" whilst you press the "power" key and let go as soon as the ASUS logo appears. Once you're in the UEFI setup screen, you can disable "Intel RST Premium with Intel Optane System Acceleration" by going to Advanced tab-->SATA Configuration-->SATA Mode Selection-->AHCI (it should be highlighted black)-->pressing Esc-->Save & Exit tab-->Save Changes and Exit.

​

Secondly, let me say that the dual screens is a *lot* more than a gimmick... I bought this laptop *partly* because I thought I *might* have a use for dual screens and *partly* because I want to support ASUS' vision of "future laptops", but *mostly* because it's unique and I wanted to see how it ran under Linux-based operating systems - which is *surprisingly* well.

I find that I use the bottom display *all the time* \- my e-mail stays there and when I'm performing a task that *only* requires my *supervision* (e.g. uploading files to my websites or copying files to / from another computer or storage drive), I'll have the relevant program on the "lower" display, whilst I continue to work or play on the "upper" display.

*Definitely* a step in the right direction for the future of laptops, and far *more* useful than the "TouchBar" on my son's (over-priced!) Apple MacBook Pro!

​

That's not to say everything is perfect - there are *some* things that don't work or don't work as they *should*, but in all fairness, this is to be *expected* when you have a laptop that is *especially* unique from a hardware perspective.

​

**Screen and ScreenPad Plus**

Both screens work "out-of-the-box" and the lower screen accepts "touch" input - though I don't have a stylus yet (waiting to hear back from ASUS if there was *supposed* to be one in the box or not), so I haven't played around with this too much... Ubuntu "sees" the lower display as a second built-in display, and you can join both displays, mirror them or use them as separate displays. You *will* need to initially go into Settings and "drag" the smaller display *below* the main display though, because the *default setting* is to the *side* of the "upper" display (Ubuntu *will* remember this choice between reboots, so you will only need to do this once): Settings-->Screen Display.

The brightness can be adjusted on the "upper" display, but frustratingly *not* the lower display at the time of writing... I have seen some stuff online in reference to the ZenBook *Pro* Duo that suggests there *may* be a work-around for this until it is fixed in Ubuntu, GNOME and / or the Linux kernel, but I have not looked into this just yet.

There are hardware keys to swap the content on both screens (i.e. the content on the "upper" screen moves to the bottom, and vice-versa), and disable the "lower" screen - these have *no effect* under Ubuntu 20.04 LTS ("Focal Fossa") at the time of writing. You *can* disable one display or the other in Ubuntu's settings; if you disable to "upper" screen it will switch off *completely*, if you disable the "lower" screen, it will show no content, but the backlight is still on (i.e. it's just a "black", backlit screen with no content).

​

**Touchpad / Numeric Pad**

The touchpad works

just as well as any other touchpad and you can enable / disable it using either the keyboard shortcut ("F6", when the function keys are *disabled*) or Ubuntu's respective setting (Settings-->Mouse & Touchpad-->Touchpad-->Touchpad)... Try as I might, I have *not* been able to get the numeric pad to appear as yet (it's *supposed* to display a touch-sensitive numeric pad when the touchpad is *disabled*) - I'm still trying to clarify the *method* which should be used under a Microsoft Windows-based operating system to achieve this, but at the time of writing I have had no luck under Ubuntu 20.04 LTS ("Focal Fossa") using various methods.

​

**Keyboard**

By *default*, the keyboard will have the "function" keys enabled after *every* reboot, even if you change this setting using the respective keyboard shortcut... I have not yet found a way to *change* this behavior, so if you're like me and prefer the "secondary function" of the function keys (e.g. volume or brightness adjustment) to be the "primary function", you will need to turn change this after *each reboot*: hold "Fn" and press "Esc" (the light on the "Fn" key *should* go off).

All of the "secondary functions" on the "function" keys (volume, brightness, etc...) seem to be working *except* for "F10" (which *usually* turns the camera on and off - it has no effect under Ubuntu), "F11" (screen-capture tool - it has no effect under Ubuntu) and "F12" (My ASUS - it has no effect under Ubuntu)... You *should* be able to change the function of these non-working keys in Ubuntu's settings (Settings-->Keyboard Shortcuts), though I have not *yet* tested this.

​

The UEFI conveniently allows you to disable or enable certain functionality (such as the camera, bluetooth, etc...) at a *UEFI level*, though I have not yet tested this because like many people, I'm working from home at the moment and need all this stuff active (under normal circumstances, I would disable the camera)... Interestingly, the UEFI refers to a *card reader*, which does not seem to be mentioned in the specifications and is seemingly not present - I might have to look into this a little further (not that I actually have a *need* for a card reader).

No other issues have been identified at the time of writing. I can see that the ZenBook *Pro* Duo has some problems with the wireless networking (Wi-Fi) card and detecting the battery capacity - I have *not* had these problems with the ZenBook Duo. I also did *not* need to switch off SMART or Fast Boot, as some ZenBook *Pro* Duo users say they have had to do.

Lastly, some people say that they have had issues resuming from suspend with the ZenBook *Pro* Duo - I have *not* had issues resuming from suspend with the ZenBook Duo and as best I can tell, the laptop is in fact suspending when I close it (the laptop).

​

I will update this post if I identify any other issues or test any other stuff that I've missed.

​

Feel free to post any questions below and I will do my best to answer them...

Running Linux on Android on Samsung DeX is pretty neat!

As many of you guys know, there are ways to get Linux running on top of Android if you are willing to deal with certain limits. I wanted to see how far it can go. I was able to use Andronix and Termux to get a working version of Fedora 30 (aarch64 version) on my S9+ and was able to get a xfce desktop which can be vnc'd into. I am surprised at the performance given that I was only at 35% battery and that I was basically running everything at once.

For the future I want to get the cycle renderer for Blender, get updated GetDP solver, get some OpenFOAM/Calculix/Elmer/Su2 solvers such that I can visualize with Paraview.
