Using 2 External HDMI Monitors to a Macbook Pro 2017 without Mirrorring External Displays

My Macbook Pro 2017 is currently connected to an external HDMI monitor through a hub. This hub occupies both USB-C ports on one side of the laptop and contains a HDMI output which is connected to the external monitor.

enter image description here

Can a second external monitor be connected to the Macbook pro via HDMI without having it in mirrored mode due to Mac’s lack of support for MST? I am thinking of getting a USB-C to HDMI adapter and connecting this to the existing USB-C hub, will this allow the 2nd external monitor to extend instead of mirroring the first external display?

rooting – Android 10 forensics – Root a cellphone without SD Card and without installing any external apps

I would like to root my Samsung J6 mobile phone that is running Android 10 in order to apply forensically sounding techniques on it (basically recovering deleted data etc). So far, as I researched on web, all of the rooting methods require installing of softwares such as magisk to a component such as either SD card or internal memory of mobile phone. The thing is, I don’t have an SD Card inserted on the phone, and I don’t want to install any external software into my cellphone memory. Is there any way to root this cell phone without installing any app into its memory(rooting via using only connected computer)? Any help will be appreciated.

macos – External display: After standby, window positions are reset (MacBook Pro clamshell mode)

I’m running macOS Big Sur on a MacBook Pro 15-inch 2017 in clamshell mode with an external display (LG 27UD58). I almost never open the laptop or disconnect it from the display.

After I wake my MacBook from sleep, the windows all gather in the lower-left corner, instead of remembering their previous positions.

Is there a way to fix this?

I thought that maybe there is an LG driver I could install but I couldn’t find anything. I’ve seen similar reports by other users but haven’t come across any solution so far.

Thanks for your help!

configuration – How to bind maria-db server to external ip on eno1 and vlan ip on eno2

Server version: Ubuntu 18.04

On eno1 I have an extra failover IP configured
On eno2 I have a VLAN configured

I read that MYSQL can bind to more than one IP using separated with a comma.

My question is, can I bind a failover IP from eno1 and a VLAN IP from eno2 like so?

bind-address = vvv.vvv.vvv.vvv,

Triple checking before I commit to the install and configuration.

macos – How to automount an external drive to hold ~/LIbrary

Xcode simulators as usual multiples and expands
turning ~/Library into a dumpster

now on 256gb drive there is no space to install xcode 14.2 and i;m thinking to resolve the issue extensively
buying an external 0.5tb drive

How could I auto mount it to ~/Library
upon login and migrate all the stuff that’s currently in ~/Library to it?

could I just mount it in ~/.profile ?
I assume user interaction is needed if I sudo mount anything and .profile / .bashrc was meant to run without UI.


bcs – Unable to access data from external list by REST API

I’m trying to retrieve items from external list by REST API. The external list displays data from SQL Server view. Unfortunately I always get error saying that the list does not exist. This happens both in the case of using api by GUID (like _api/web/lists(guid’96A46528-61AC-4130-8533-67978DAC8A14′)) or by title. I’ve also retrieved all the lists (_api/web/lists) and there’s no list by that ID or title. What could be the reason?

macos – Is it okay to use an external flash drive to store a Photos Library?

I’m getting an M1 MacBook Pro from my employer which only has 512 GB of flash storage (my 2018 MBP has 1 TB), so I’ll need to move my 350 GB Photos library to an external drive. I know that I could have Photos optimize for storage (I do have iCloud Library), but I think it’s best to have the full-size Photos library stored somewhere.

Would it be okay to store the Photos library on an external thumb-type flash drive from a reputable manufacturer such as SanDisk, or should I stick to a more conventional external USB flash drive, such as the SanDisk Extreme series?

unity – Can i use a method to change a variable that is external to it?

I’m trying to change two booleans that exist outside my method. I read about passing by value and passing by reference and in this case i think the correct way is to use passing-by-reference.

However, it is not working. I call the method and my booleans still with the same value as before the calling.

Can someone help me?

MacBook Pro/MacOS BigSur external monitor issue with display Resolution/sharpness/Color

  • Get the correct EDID data

    • You may need to understand what is EDID data etc. Which is given in this question
  • However, in MacOS BigSur, now everything is SHA protected. So, you cannot write anything to /Systems/ folder of it (which is a good thing for protection)

  • Now follow the instructions given in this link to copy the override instructions.

(Basically, you need to copy the overrides to /Library/Displays/Contents/Resources/Overrides/DisplayVendorID-*)

Hope it helps to someone…
