keyboard – Revert back from a BT dongle 4.0 to internal bluetooth controller won’t work

When the Mac mini 2018 was released, I was experiencing Magic Mouse 2 issues (choppiness, etc), like many others, so I decided to get a Bluetooth 4.0 dongle (IOGear GBU521) and see if the problem would go away. It did…

I plugged in the new adapter, went into Bluetooth Explorer, under “HCI Controller Selector” selected my adapter “Broadcom Corp, Location ID XXXXXXX”, made it ACTIVE and I was good to go. From memory, I don’t believe I did anything else to get this to work. One thing though. When I would reboot, it would go back to the internal Bluetooth controller so after reading about it, I used this Terminal code sudo nvram bluetoothHostControllerSwitchBehavior=always and all was good…

A year later and after moving my workstation around, I would like to go back to using the internal Bluetooth controller but it seems I can’t.

This is what I did… I unplugged the dongle and the mouse and keyboard no longer show under the Bluetooth devices panel, for me to Connect to. So I tried the following…

1- Unplugged all devices and hubs going to the Mac mini except for a wired mouse, keyboard and monitor so I can set things up.

2- I entered this code in Terminal sudo nvram -d bluetoothHostControllerSwitchBehavior (to go back to the default setting).

3- I trashed com.apple.bluetooth.plist & com.apple.bluetooth.xxxxxxxxxx (random numbers and letters)

4- Shift-Option to Debug (Reset the Bluetooth Module, Factory reset all connected Apple devices, Remove all devices) re-booted.

5- PRAM (Option-Command-P-R)

6- SMC (Unplug AC cord, 15 seconds, replug and wait 5 seconds) Reboot.

I’m not sure what I may be missing here but all that I’ve tried so far isn’t working and I’ve tried it multiple times. Maybe there’s a Kext file I need to delete (replace) but I’m not sure what to do. I know I can plug the dongle back in again, and the mouse and keyboard will show up in the Bluetooth panel but I shouldn’t have to anymore. Actually, when I also plug in an older Bluetooth 2.0 dongle, I’m able to connect devices to it. Very strange.

Any help or advice would be appreciated.

Thank you.

iphone – Apple Watch deletes all songs from its internal store after iOS sync

I have an iTunes playlist with 150 songs set to sync with Apple Watch. I sleep, let the Watch on its charger, then by morning I have all 150 songs on it working fine. I can confirm this by going into the Watch app then General > About. However, whenever I sync my iTunes with my iPhone, all songs are automatically deleted from the Apple Watch, even if the playlist is still the same (on the iPhone nothing happens, everything is still fine). Then the songs will only be synced again when I put it back on the charger.

Anyone knows why it might be happening?

Thank you!

Apple Watch Series 3 – WatchOS 6.2.6

unity – Does animation have internal “update”-cycle where I can make calculations between steps?

I am new to Unity and not game developer at all, so sorry if this question might be stupid. I have an animation in my project. Is there some points where Unity calculates/recalculates the next position of animated character? Is there some function like for example “OnAnimationSample()”? I want to make calculations between theese points. I didn’t found anything in the documentation and hope that someone more experienced than me know some way to tackle, although the task is quite peculiar

seo – Should I use rel=”nofollow” on already existing internal links?

I have a big video website. It’s not in the index yet, I try to do my best for better indexing before opening and now I have a question. New videos are displayed on the main page and there’s a navigation for accessing pages with an older videos. On the page with any video there’s a section with related videos (without navigation). There are no videos displayed that the robot couldn’t access through the main page. Furthermore, these videos a little bit changes with every page refresh. Should I add an rel="nofollow" attribute to links in this section?

Chrome “Secure DNS” setting in v83 breaks access to internal websites

I have found that if I attempt to access a web based service internal to my home network then Chrome will fail to properly resolve the URL. An example would be if I were to try to browse to my Plex server using its fqdn; plex.mydomain.com. This is only if the “Secure DNS” setting is enabled. It appears to be directing my web requests to a DNS server outside my network. Rather than taking me to my Plex server web frontend I’ll actually be redirected to a page on my pfsense router with an error warning me of a potential DNS Rebinding attack.

I run my own internal DNS server. It’s a simply Windows 2012r2 server. Everything on my internal network is pointed to this server, which is configured to forward requests to Google’s DNS server for records that it doesn’t know about.

I like the idea of using Secure DNS (or DNS over HTTPS). But I can’t seem to use it for the above reason. I’m wondering though, if I were to configure my internal DNS server to support DNSSEC then that might fix the problem. I’m thinking I’d also need to adjust my Chrome settings to use my internal DNS server for it’s Secure DNS service. Does that all sound correct?

Has anyone else observed this problem?

wallet – Bitcoin Core internal Electrum Server

I think the preferred technique to use ‘bitcoin core as a wallet backend’ is through block filters, like the new compact block filters (an improvement over bloom filters). The protocol is known as Neutrino and lowers the CPU and storage requirements for your bitcoin core node (an electrumx database takes around 50 GB right now). To create these filters in bitcoin core, you need to launch add the bitcoind option blockfilterindex=1 or blockfilterindex=basic. With these filters, you can filter for blocks that affect the addresses (scriptPubKeys) that belong to your wallet. Several lightning wallets use this technique

This block filtering technique produces some false-positives, so you will fetch blocks that end up not affecting your addresses. Because you are requesting more than just the relevant transactions to your wallet, you end up consuming much more bandwidth than using an electrum server but it has the advantage of being more private.

Neutrino is used by several lightning network wallets:

Do internal outgoing links affect rank of the origin page

I have few hundred top ranking pages (with good SEPRs) on my website. Now I would like to add links to internal pages from those top ranking pages (aimed at additional value for users). But I have a doubt if those links would dilute the page rank of the origin pages. Is my worry justified?
