macos – Installing 11.2.2 on external drives

Is anybody else facing issues running 11.2.2 from external drives?

I am trying to install 11.2.2 on an external flash disk.
I have a Samsung DUO Plus and a SanDisk Ultra Dual Drive.

The SanDisk was running Catalina and I tried to update it to Big Sur via the App Store but it get’s stuck at “Less than 1 minute remaining” when installing.

The Samsung (fresh install) starts failing at some point during install, gives a kernel panic and reboots. That whole process repeats itself until i force the machine to shut down.

Installing Catalina on the Samsung works fine. Then updating that to Big Sur ends in an Apple logo boot-loop.

The issue occurs on a MacBook Pro 15″ 2018 as well as a MacBook Air 13″ 2015.
I’ve downloaded the installer multiple times and tried using the installer on the internal MacBook Pro drive (with success) to rule out issues with the installer-image.

logging – Do external harddrives keep track of the computers they’re plugged in to?

I know that it’s possible for a computer to set up logging or auditing, and keep track of what devices are plugged into IT. But do external harddrives keep track of what computers THEY are ever plugged in to? Intentionally, or unintentionally? (Assume they have just been taken out of the box from Best Buy — specops IT hasn’t loaded anything on.)

I’m trying to analyze a Samsung T5 right now but I want to know in general.

If the answer is Yes, or Maybe, should wiping the hard drive get rid of this information, or is it stored DEEP in the drive, somehow? I’m always suspicious of how much “wiping” does, even with a multi-pass algorithm.

How to List Custom-Made Files From External Storage Using The file Extension (eg: “.mp3” or “.m4a” or “.xyz”) – Android Studio

I want to retrieve files from my android device and list them in a List View or Recycler View. I need to do this using the files extension so that I may also retrieve custom-made files with their own file extension, eg: “.xyz”. This is what I’ve done so far

public static ArrayList<MyFiles>getAllFiles(Context context){
        ArrayList<MyFiles>tempList = new ArrayList<>();
        Uri uri = MediaStore.Files.getContentUri("external");
        Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
        if (cursor!=null && cursor.moveToFirst()){
            while (cursor.moveToNext()){
                String path = cursor.getString(cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA));
                String title = cursor.getString(cursor.getColumnIndex(MediaStore.Files.FileColumns.DISPLAY_NAME));
                String ext = title.substring(title.lastIndexOf(".")+1);
                if (ext.equals("mp3")||ext.equals("m4a")||ext.equals("xyz")){
                    // check...
                    Log.e("path: "+path,"Name: "+title);
                    //adding the path and title to my Model Class
                    MyFiles myFiles = new MyFiles(path,title); 
        return tempList;

This method successfully returns a List of files with “.mp3” and “.m4a” extensions but files with the extension “.xyz” are not showing. What am I missing, or is there a better way of doing this?

nat – Which MPoA bridging protocol to use for delegating the public IP to an external router?

I have a DrayTek 130 VDSL2 modem, which uses PPPoA for connection. My ISP requires CHAP for authentication, but I am using an alternative OS on an external router, whose PPP plugin does not work as one would expect, thus having trouble with establishing a PPP link on my ISP’s network.

Before I could paraphrase my question, I’d like to make it clear what I am trying to achieve:

  1. Eliminating the need for PPP authentication on the external router by saving the login details on the modem.
  2. Disabling the LAN and delegating the public IP to the external router.

As for the first objective, I have found the corresponding options in the console, allowing me to save the login details, but unfortunately it turns the device into a router and I can not use the public IP on the external router for NAT.

As for the second objective, I have turned on the MPoA with bridged LLC, allowing me to delegate the public IP to the external router, but in this case I have to use PPP and CHAP on the external router for authentication.

Unfortunately I am unable to do both in the same time.

First of all, is it possible at all, to delegate the public IP to an external router without having two public IP addresses?

This modem offers three MPoA bridging protocols: LLC, VC-MUX, IPoE. My question is which one could solve both my problems?

spells – Do external, non-innate methods exist in Faerûn circa 1489 DR to situationally alter the efficacy of spellcasting?

Prior to D&D5e, Forgotten Realms lore included various situational methods and circumstances that could change the way spells and spellcasting worked. For example, the 1e product Volos’ Guide to All Things Magical includes a lengthy section on the use of various materials as special spell components. Using, say, a star sapphire in the casting of globe of invulnerability would increase level of spells warded off by the globe (see VGtATM p. 51). On the other hand, consuming the herb spellbane detailed in the 2e product Volo’s Guide to Cormyr would entirely suppress spellcasting ability for a period of time (VGtC p. 110).

Faerûn has changed a lot across editions, however, and nowhere is that more true than in the way magic and spells work. Maybe those old methods of amplifying or weakening spells and spellcasting are still effective, or maybe they aren’t. Is there any lore either way in 5e-era publications, i.e., in the Realms as they are post-Second Sundering, circa 1489 DR? Are there any other, different but comparable methods available?

To be clear, I’m interested here in methods that are temporary, ephemeral, and external to the caster and/or target — not innate abilities, learned skills, divine gifts, etc. Magic items are fair game, as are special substances (magical or otherwise). Even locations with special properties that change the way spells function would fit the bill.

unix – BASH: List External drives

I am trying to make a script that list all disk on my Mac exluding /dev/disk0 and /dev/disk0 (I only want it to show the external and virtual drives) and the name of the primary partition.

Something like this:

1.- USB1    /dev/disk2
2.- USB2    /dev/disk3
3.- USB3    /dev/disk4
4.- USB4    /dev/disk5

I am pretty new to Bash scripting – How to fix Photos error while trying to open iPhoto library from external hard drive “Photos was unable to open the library” error 4302

Any idea how to get it to open?

Found this thread googling – – but don’t understand the proposed solution.

linux – How to output rEFind boot interface to external monitor

I connected my AOC monitor through HDMI to my HP laptop. And I am using rEFind as a boot manager to choose between Arch Linux and Windows 10. But the rEfind is shown only on my laptop monitor.

I understand that at this moment of booting there are not drivers loaded for the monitor, because this is happening during the OS boot process. But I know, that for GRUB for example there is a way to set the output through some options in it’s config file.

So is there any way to make rEFind show it’s interface on external connected monitor?

Also people say that there is an option in a BIOS to boot into specified monitor (external/LCD). But unfortunately there is no such option in my BIOS version.

photos – Can i store and access iphotos library on external hard drive (and still have it backup to my cloud network)?

Apologies for my technical ineptness. What i aim to do i store my large iphoto library on an external HDD and access it from that so it does not us my laptops more limited SSD storage. Is it possible i can set this hard drive to backup via my computer to the same local network attacked storage that my computer backs up to. If so how would this been set up?

Cheers, Ben.
