Find My Device is completely useless until the device is unlocked. As long as it is rebooted and not unlocked, there is no way to detect its location. Since most phones (if not all), use an encrypted filesystem. With such, no service can’t start if the device isn’t initially unlocked after reboot, including Find my device.

This isn’t only a issue with Google’s implementation, it’s the same with other implementations to.

Feel free to try it by yourself. Nothing easier than that. Reboot your phone and try to find it via Find My Device or ring it, without to enter your password before. It will not work.

BTW: it doesn’t make sense to exclude security and privacy related things from encryption. Otherwise there would be an unusually high risk to compromise this sort of data.

I wonder the same, some time ago but for different reasons. If I have to buy a gaming laptop, what should I choose? Intel CPU and Nvidia was my best friend on Windows, but on Linux I’m totally unsure. I think AMD does a better job for gaming under Linux, but I have absolutely no idea if that’s true.

Is there some variable to use as placeholder for the current logged in user, or do I have to use one gid/uid for all users on the laptop?

laskobar, 9 months ago

Ohhh nice. I will try that one. Have used only a simple battle mixer and the good old sl-1200 mk2 for several years. Maybe it’s time to try some digital mixer. Nice that there is something for Linux… Thx for the link.

The depth is changing constantly, because new subdirs are created and removed during the day and/or upload/sync process. Thats why the script is walking across the complete directory structure every time. But the dummy file is a nice suggestion. In this case, I can monitor only the dummy file and trigger the script on dummy file change. Good idea.

Since the script I’m talking about, makes some changes to the synced files, this is not a job for Resilio Sync. For the sync job itself, I’m using SFTP, because this is the easiest to setup on all clients/platforms. I’m only interested how I could safely dedect, if the sync is finished and start the script to do it’s job’s. The tip with the changing file is nice. I’m using that for now. Absolute reliable so far, for this task.

It will use your current profile with settings automatically

Not really. There is only a Switch with GBit and standard FritzBox 7590 as a Router. The Switch is connected to the Router on the WAN Port as it should be (if i remember right) and the RPi4 to one of the Switch ports. The Laptop is directly connected to the router. The cable is a standard GBit cable. There should be nothing with 100MBit.

The speed looks fine for me on the Laptop itself:

<pre style="background-color:#ffffff;">
<span style="color:#323232;">/dev/sda:
</span><span style="color:#323232;"> Timing cached reads:   28080 MB in  1.98 seconds = 14161.28 MB/sec
</span><span style="color:#323232;"> Timing buffered disk reads: 448 MB in  3.02 seconds = 148.55 MB/sec
</span>

<pre style="background-color:#ffffff;">
<span style="color:#323232;"> /dev/sda:
</span><span style="color:#323232;"> Timing O_DIRECT cached reads:   604 MB in  2.00 seconds = 301.42 MB/sec
</span><span style="color:#323232;"> Timing O_DIRECT disk reads: 454 MB in  3.02 seconds = 150.36 MB/sec
</span>

On the Pi itself i get:

<pre style="background-color:#ffffff;">
<span style="color:#323232;">/dev/sda:
</span><span style="color:#323232;"> Timing cached reads:   1974 MB in  2.00 seconds = 988.54 MB/sec
</span><span style="color:#323232;"> Timing buffered disk reads: 196 MB in  3.02 seconds =  64.91 MB/sec
</span>

<pre style="background-color:#ffffff;">
<span style="color:#323232;">/dev/sda:
</span><span style="color:#323232;"> Timing O_DIRECT cached reads:   122 MB in  2.01 seconds =  60.64 MB/sec
</span><span style="color:#323232;"> Timing O_DIRECT disk reads: 194 MB in  3.03 seconds =  64.03 MB/sec
</span>

This also much above the speed, i got, when i transfer files via SFTP/SCP.

I have tested also iperf and got: 0.0000-10.2100 sec 113 MBytes 93.1 Mbits/sec

It seems like this is really somewhere limiting to 100MBit.

laskobar, 10 months ago

It seems the limiting factor is the switch or cable. If i connect the Rpi to the router directly, i get: 0.0000-10.1222 sec 281 MBytes 233 Mbits/sec

laskobar, 10 months ago

Its the cable. After changing the cable between the Switch and the Router, i got iperf test up to: 0.0000-10.0416 sec 1.09 GBytes 932 Mbits/sec.

We had some workmen in the house a few weeks ago. Apparently, they damaged the cable. The test cable was unfortunately too short for permanent use, but it was enough for testing. I now get an upload of 65MB/sec on an average. This is about the same as the limit I had already determined through hdparm on the RPi4. I don’t know, why hdparm is faster directly on the laptop, maybe the USB Controller is not the best on the RPi4. But anything is better than 11MB/sec.

The situation is different when the laptop is only connected to the network via WiFi. Here I get a maximum of 28MB/sec. I have not yet found a solution how this could be faster.

Alles gut :-) Das Problem ist gelöst. Die Dachdecker haben das LAN Kabel beschädigt. Werd mal ein Neues am Montag ordern. Ich hasse es nur, das Kabel zu verlegen. Das liegt teilweise unter dem Laminat im Flur, was ich mühsam verlegt habe. Was solls, da muss ich wohl durch.

I’ve been testing KDE for several weeks now, XFCE before that but I’m back to Gnome. It just feels right. Everything is where I expect it to be. No searching in thousands of menus. What scares me about KDE is that there are tons of options and stuff that no one will ever need. Especially KMail I find just awful. So many options and you only find what you are looking for, after an extensive search via a search engine of your choice. This is totally frustrating. XFCE does a lot better here, but I miss the one or other pleasant animation when opening windows and the like. Gnome, on the other hand, isn’t great either, but I feel most comfortable here.

Ahhh thats it. Many thx.

I have not much mods enabled. Only colored icons, from time to time “build info” when I have to check air leaks and some scripts like PAM and AutoLCD. The rest is Vanilla+DLC’s. I have hoped that I can remove PAM and can use Automatons for the same task, but this isn’t capable of automatically mining as of yet

laskobar, 10 months ago

I will have a look in the evening. Many thx for the tip.

laskobar, 10 months ago

What do you mean with Proton folder? Is this the game itself under “SteamLibrary” (in my case /mnt/games/SteamLibrary/steamapps/common/SpaceEngineers)? Or is there some other folder do clear?

laskobar, 10 months ago

Many that makes it a lot more clear, which folder is meant. I will try that and report later, if that works. Many thx. I will also try GE variant.

laskobar, 10 months ago

Not really. In my case i start it from within Steam Library and not from commandline, but i have tried the --force -q dotnet48 shortcut also, with no positive result. Yesterday, I could play the game for more than 3 hours, but today, starting it the same way, it crashes after loading 1% of the save game.

I’m starting it now in a parallel installed Windows, where the save game location is shared between both OS (-appdata “/path/to/folder” -skipintro). Maybe i find a better way and must not boot to Windows. Since i start this really seldom, it has to download a lot of Updates before i can continue.
