google pixel – How to set default Alarm app when Open by Default menu is disabled?

So, I’m trying to change my default alarm in Google Assistant (Pixel 5) to another alarm clock app I have installed (Alarm Clock Beyond). When I tell the assistant “Wake me up in 5 minutes”, it just uses Google’s native clock app. The default menu for the clock app is disabled, and I haven’t been able to make any progress on this.

sorting – In LibreOffice Calc, why would sort buttons and menu items suddenly become disabled?

I was creating a spreadsheet in LibreOffice Calc. Several times, I used the “Sort Ascending” and “Sort Descending” toolbar buttons. All was well, and everything was working as expected.

As I continued to edit my spreadsheet, I noticed that all the “Sort” toolbar buttons were dimmed, and so were the corresponding menuitems.

Why would all the sort functions suddenly become disabled in LibreOffice Calc? All other functionality appears to be working.

If it matters, I’m currently using v7.1.2.2. I did try closing LibreOffice Calc and restarting it, as well as rebooting the system.

Chrome Tab Grid Layout can no longer be disabled via chrome://flags, is there another way?

Doing some more research, I find that this is no longer enough

Update: That used to be it, but with the most recent update Google broke this fix, but never fear there is a temporary solution to make it work again.

  1. Type “chrome://flags/#temporary-unexpire-flags-m88” into the address bar
  2. Tap on the drop-down menu in the Tab Grid Layout entry
  3. Select “Enabled”
  4. Tap the Relaunch button at the bottom of the screen

I suspect that will only be a temporary solution though.

homebrew – brew gives: “Error: gocryptfs has been disabled because it requires FUSE!” during encfsgui installation

I’m receiving errors while installing pyencfsgui

When I run brew install encfs or brew install encfs I get the message Error: encfs / gocryptfs has been disabled because it requires FUSE!

I’ve installed the osxfuse brew package and rebooted my mac.

After receiving the error message above, I installed the macfuse desktop package and rebooted my mac again.

Scheduled disabling of android apps that cannot be disabled during the active period

I’m currently using FocusMe to accomplish this task. The issue is that I can just uninstall the app during the active period to get access to my previously disabled apps. I need a solution that will make it impossible (or just really time consuming) to disable a scheduled disabling of apps on my android phone. I haven’t found an app that can do all of this and i haven’t found an "app lock" app that will completely prevent me from uninstalling FocusMe (or whatever other app) and the "app lock" app. If I have to I can root.

networking – Wifi Hotspot – Getting 504 Timeout (and CORS) when cache is not disabled

I have an android phone that I’m using for wifi hotspot to which I connect my laptop to. There is generally no problem with it however sometimes content just doesn’t load.
I tried checking the Network DevTools to see what the problems are and figured out what requests were causing it. The causes were requests to a different domain and they are in “(pending)” status for a long time and eventually turning “CORS error missing Allow Origin”. Upon examining further (using a different network) the responses properly have the needed headers and the requests properly have the origin matching the allow orgin header. When I tried checking again (with the mobile network), the response it receives is the 504 Gateway Timeout (which doesn’t have the allow origin header) so Network DevTools i think treated it as CORS.

Now the thing is, when I try to use the “Disable Caching” feature of devtools everything works fine (except that caching is disabled so it eats quite more). So I am not sure what would be the cause of the 504 timeouts and if possible find a solution for it.

I’ve also noticed that I can load the requested url on a different tab and then that specific resource would load fine on the main site I was visiting but doing this for every resource is pretty tedious and doesn’t really fix the issue. I have also tried using a different android device with the same SIM but it still had the same results.

As a band-aid, I was thinking of disabling cache for the specific domains but I am still unsure of how I will do it.

differential equations – WhenEvent disabled in NDsolve

I try to simulate particle motion in electric field. Ex and Ey is the intensity of electric field in X axis and y axis resepectively, which is related to the position of particle.

g = 9.8; q = 1.08 10^-13;
s = NDSolve({m x''(t) + 6 (Pi) (Eta) R x'(t) == q Ex(x(t), y(t), t),
     m y''(t) + 6 (Pi) (Eta) R y'(t) == q Ey(x(t), y(t), t) - m g, 
    x(0) == 0, y(0) == 100 b, x'(0) == y'(0) == 0, 
    WhenEvent(1 b < y(t) < 5 b, y'(t) -> -0.35 y'(t))}, {x, y}, {t, 0,
     0.1}, Method -> {"StiffnessSwitching", 
     Method -> {"ExplicitRungeKutta", Automatic}}, AccuracyGoal -> 2, 
   PrecisionGoal -> 4, Method -> {"DiscontinuityProcessing" -> False},
    MaxStepSize -> 10^-6);
StepDataPlot(s)
ParametricPlot(Evaluate({x(t), y(t)} /. s), {t, 0, 0.1})

WhenEvent describes that when particle land on the plane, it will bounce. Initially, I wrote like this
WhenEvent(y(t)==0, y'(t) -> -0.35 y'(t))}

enter image description here

I thought Ndsovle might miss the point. So I enlarge the the section of WhenEvent and minimize the Max step size. But it still doesnot work.

I do not know Whether I set the parameters wrong or use the wrong method.

Sometimes, it will notes that Singularity or stiffness problesm, so I add “StiffnessSwitching”. And the function of Ex and Ey is piecewise periodic function, so I add Method -> {"DiscontinuityProcessing" -> False}

I am a rookie in using NDsolve. I am still learning it in dealing with particle trajectories. Thank you very much for any constructive ideas.

Here is complete code. Most of the previous ones are for calculating the electric field. If you have time to comb through the code, just run it. Thanks again.

Windows 10 File Explorer Navigation Pane Toggle Disabled

My folder options are set to open Windows Explorer to the This PC page. But whenever I first open explorer, I cannot toggle the visibility of the navigation pane. I can navigate to a different folder and then back to This PC, the navigation pane is enabled again. How can I toggle the navigation pane without having to change directories first?
