How to Download and Custom Install Office 2024 / 365 Choose only the Apps You Need
This write up is based on this video.
https://www.youtube.com/watch?v=w9q_rqjD0XU
I chose this video when there are many videos on this topic because it is up to date. I used the file to download the Office programs and the process worked.
You may want to read this KB first before starting to get the general overview of this Office Deployment Tool.
Overview of the Office Deployment Tool
https://learn.microsoft.com/en-us/microsoft-365-apps/deploy/overview-office-deployment-tool
Below is the configuration file. It is just a plain text file. Open a blank file in your preferred text editor and paste the text below on it. Save this config file with the xml extension. The file name is configuration-Office365-x64.xml
Everything between the open and close <!-- comment tag is ignored by the script parser which is the accompanied Setup program. The Microsoft 365 ProPlus edition has everything that most of us ever needs. These include Word, Excel, PowerPoint, Outlook, OneNote, Access, and Publisher (Access/Publisher PC only). I explicitly added Bing, Groove, Lync, Onedrive, Teams, Designer, Clipchamp, Copilot, Visio, and Project to the exclusion list because these may get installed by accident, taking up disk space and download time. Remember, the config file explicitly specifies to the Microsoft server to download and install only the programs on the list from the Microsoft 365 ProPlus package.
However, the list does not explicitly include Word, Excel, PowerPoint, and Outlook. However, these programs will be downloaded and installed once the script is run.
The Product ID on the script says O365ProPlusRetail. It is the ID for the Office 365 Enterprise E3. Below is the KB on the various product IDs for these applications and plans.
You can experiment with various IDs to get the specific software you want.
<!-- Office 365 client configuration file sample. To be used for Office 365 ProPlus apps, Office 365 Business apps, Project Pro for Office 365 and Visio Pro for Office 365.

Unable to add a Gmail account to classic Outlook
Many people still use the Outlook program with its classic interface, still possible with the latest Office 2024 Outlook program or part of Microsoft/Office 365, this is a big problem. Microsoft has a KB for this specific problem.

Create a USB installer for macOS 26 Tahoe
Type softwareupdate --fetch-full-installer --full-installer-version 26.0 in the Terminal. This will fetch the DMG to the Applications folder. Presumably when newer versions of Tahoe are release, you have to modify the number in the command.

Windows 11 IoT LTSC
I installed Windows 11 IoT LTSC and regular Windows 11 Pro, both 64bit and 24H2, on the same computer that has only 8GB of RAM to see what computing resources each version of Windows 11 take.
The IoT LTSC version by itself consumes 4GB of the RAM (50%) and 5% of CPU idle. Its footprint is 30GB of disk space.
Oddly, the regular Windows 11 Pro install uses the same amount of disk space and RAM (50%) usage, but less CPU (3%) usage.
Therefore, from this limited test, running the IoT LTSC version has no performance advantage other than getting longer support.
General support for Windows 10 expires in 2025 because its GA (general availability) was July 29, 2015. However, the IoT LTSC version of Windows 10 based on 22H2 continues to get support until January 13, 2032.
Windows 11 GA date was October 5, 2021, meaning Microsoft will stop supporting it in 2031. For the IoT LTSC version based on 24H2, its support ends in 2034.

Synology DS223j Missing drive JBOD

I put some test data on the volume. Then after I have shutdown the NAS, I physically removed Drive 2 from the set. Then I turned the NAS back on. The NAS did turn on, but making a beeping sound. I could still log into the DSM 7.2 via the web interface, but it told me that one of the drive was missing -- as expected.
So what happened to the data? Unfortunately all the shares in the volume were inaccessible. They did not even show up in DSM File Station. I had hope that only the data in the removed drive would be missing, but the deleterious effect was global.
When I put Drive 2 back in, but removed Drive 1, the result was the same. All data was inaccessible. Basically, in a JBOD configuration, presumably applying to all Synology models with multi-drive configurations, the data is lost when one drive is removed or non-operational. This is the same effect as a RAID-0 set.
I had to rebuild the volume from scratch when a blank drive was put back into the storage pool.

Convert macOS Sequoia.app Installer to ISO
When you download any operating system to install on a computer, it is always a good idea to download the OS from a reputable source, namely Apple for macOS and Microsoft for Windows. This is to avoid malware in these files. The operating system is the foundation of any computer. Therefore, it has to be as clean as possible.
Microsoft offers the ISO file of Windows so you can create a bootable USB drive from it. The ISO format is a flexible format that can be used for other purposes. Another use is to mount it as if it were a physical CD so you can install Windows, or any OS, as a guest OS on a virtual machine created by VMWare, VirtualBox, or Parallel.
Apple, as usual, does things its own way by not offering its macOS files in the ISO format. When you download macOS Sequoia for example from the Apple App Store, it is is the .app format which is similar to ISO, but unfortunately does not have the flexibility of the ISO format. Therefore, when you want to install Sequoia inside a VMWare virtual machine, you have to convert the .app file to an .iso file. Again, Apple doe not make this conversion simple. Fortunately, it is possible to do so without the need to use a third-party program may inject malware into the resultant file during the creation process. If you don't mind doing some command line work in macOS Terminal, this can be done.
- Download the "Install macOS Sequoia.app" from Apple using the App Store. As said, this ensures the file is free of malware.
- Copy the file called “Install macOS Sequoia.app” installer from the Applications folder into your Desktop.
- Open Terminal.
- Create a dmg container on the desktop the size of 20GB named “Sequoia.dmg” by entering this command. You can copy and paste the command into the Terminal.
hdiutil create -o ~/Desktop/Sequoia -size 20000m -volname Sequoia -layout SPUD -fs HFS+J - Mount the Sequoia.dmg container into your device.
hdiutil attach ~/Desktop/Sequoia.dmg -noverify -mountpoint /Volumes/Sequoia - Create a bootable macOS Sequoia installer into the created dmg container.
sudo ~/Desktop/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/Sequoia --nointeraction - Detach the created bootable dmg container.
hdiutil detach /Volumes/Install\ macOS\ Sequoia - Convert dmg to cdr container.
hdiutil convert ~/Desktop/Sequoia.dmg -format UDTO -o ~/Desktop/Sequoia.cdr - Convert cdr to the bootable iso image.
mv ~/Desktop/Sequoia.cdr ~/Desktop/Sequoia.iso

Strange Bug in Windows 11 Installer
You would think that Microsoft with its virtually unlimited manpower and knowledge of its own operating system could not have made such basic mistake, but it did. When the installer for Windows 11 24H2 is created on a USB thumbdrive to be used to install Windows on a blank disk, early in the installation process, there is a bug where if you choose the default settings, the installer routine would not give you the option to pick what partition to install Windows 11 onto. You would not get this window.
Instead, the installing process will install into the primary partition. If there is an existing copy of Windows there, it will replace it. This makes creating a dual boot system impossible.
Fortunately, the buggy installer offers the option to Select Previous Version at Setup which when selected, will use the Windows 10 version of the setup where such a bug does not exist. If you choose this option, you get the desired screen with all partitions listed.

MOCA Galore
This is a long overdue update to a post I made in 2013.
https://packetrider.blogspot.com/2013/12/actiontec-wcb3000n-and-ecb3500t.html
Since then, the MOCA protocol has been updated a few revisions with the latest at version 2.5. This protocol allows network traffic at gigabit speeds to go through the coax wiring. Needless to say, to get these blistering speeds, MOCA devices have to support the MOCA 2.5 standard. Actiontec has these devices. The name itself has been rebranded as ScreenBeam. Below are the MOCA 2.5 products.
https://www.amazon.com/Actiontec-MoCA-Network-Adapter-Ethernet/dp/B088KV2YYL?ref_=ast_sto_dp&th=1
The difference between the ECB7250S02 and the ECB6250S02 is the 7250 can handle more network traffic. For a home network with less than 10 network devices, save some money and get the ECB6250S02 or its kit version ECB6250K02.
While these devices work as advertised, they have one shortcoming. Each has only 1 network port. This means you can only connect one network device to the adapter. However, other vendors of MOCA 2.5 offer adapters that have multiple network ports. One of these is Translite Global.
https://www.transliteglobal.com/moca-distribution
https://www.amazon.com/MoCA-2-5-Gigabit-Ethernet-Ports/dp/B07Z3SB1HH?ref_=ast_sto_dp&th=1
Despite what its website says, the "white" model with 4 network ports has been discontinued. I think I know why because my testing with the 2-port TL-MC84 adapter, there is an extra 3 ms of ping time when network traffic goes through these adapters. I suspect the CPU in these adapters cannot handle more than 2 network devices. The TL-MC84 I bought has an older firmware version. Strangely the vendor's website does not offer for download a newer firmware. I had to get it from tech support. I think it's their way of harvesting their customer's contact info for marketing purposes. No spam yet from them. If you need the newer firmware, here it is. Presumably, it's on the vendor's Google Drive.
https://drive.google.com/drive/folders/1UD8a-DJ-_6HNqTFvlGDYHaJnaTv8OAyg?usp=sharing
Incidentally, MOCA is not the only protocol that uses the coax cables to transmit Ethernet data. There is another called G.hn Ethernet Over Coax. It is newer than MOCA. I am not familiar with it, but I will research on if it is any better than MOCA. If G.hn allows PoE over the coax, it will be a big improvement over MOCA. One advantage G.hn has is it transmits its signal at lower frequencies than MOCA. Therefore, its signal can go farther. Low frequency signals can make use of older lower quality coax. Therefore if your home has very old coax that doesn't seem to work with MOCA, G.hn over coax may be a good alternative.

Progressive Web App
As more people access the Internet using web browsers, web browsers have to evolve their sophistication and complexity to adapt to the traditional programs people have been accustomed to, programs that are installed locally on the computers. For example, many people are accustomed to the Microsoft Outlook program that they find the interface for the online web version lackluster. How does Microsoft make the web version of Outlook, accessed with a web browser, to have the look and feel of the desktop version of Outlook? The compromise is to make the web version a progressive web app.
PWAs are installed using the offline cache of a device's web browser. This is akin to Java applets that have been fallen out of favor because they require the Java virtual machine installed first on the device. PWAs only need a modern web browser to act like this virtual machine.
When you use a Chromebook, the only program on it is a glorified version of Google Chrome. This is where PWAs shine. You can use traditional programs as PWAs to get better performance. One such program is Zoom. Running Zoom on a web browser is slow and buggy because it has to interface with the computer's microphone, camera, and speaker. As a PWA, Zoom works better at these tasks.
https://learn.microsoft.com/en-us/microsoft-edge/progressive-web-apps-chromium
When you visit a website that offers PWA version of its service, you can install this PWA by going to the Customize and Control of Google Chrome, the 3 vertical dots at the upper right corner of the Chrome browser. Then go to Cast, Save, and Share. If a PWA is available to access the website's service, you should see something like this. I use Outlook as an example.The first thing you notice when running the Outlook PWA is the removal of browser navigation buttons and the URL address bar. This makes the interface look like the desktop version of Outlook.
One side benefit is the offline nature of PWA can be used to cache an offline version of selected pages in a website so that you can browse these pages when the device is not connected to the Internet. This is basically the web crawler of the past. With PWA, the web crawler feature is built into the PWA so the website's administrator can control what pages can be cached using the PWA controls in the browser. This provides consistency of the caching across multiple web browsers. Imagine your daily routine is to visit a news website. You would casually access the various webpages while inside the PWA. Then you would hop on a bus to go to work. While you are on the bus, you can fire up this reading device and revisit the same web pages offline or only need to fetch the latest info on pages that have been modified since the initial caching, saving Internet bandwidth. Moreover, with PWAs, it is possible to access the same cached pages from different devices. You would cache the pages on a desktop, then the cached pages are synched to the PWA on a second device such as your phone at home over wifi. Then you can revisit the same pages on the phone while riding the bus where Internet connection is spotty.

Improve Your Roku Device Wifi Reception and wired network connection
Some Roku streaming devices have a USB port. This port can be used to plug in an Ethernet-to-USB adapter so the Roku device receives its Internet via a wired connection.
https://support.roku.com/article/360058027813
For TVs that have Roku built-in, try these adapters:
https://www.youtube.com/watch?v=W6vlHmwFVrQ
Adapters with gigabit 1000mbps don't work. Always try the adapters with 100mbps (aka Fast Ethernet) with USB2. Any adapter that has the ASIX AX88772A chipset in its circuitry seems to play nice with RokuTVs and Roky streaming devices that lack the network jack. It's most likely that a Roku device with a network jack actually uses this chipset. Don't be worry about the "slower" 100mbps speed. It is fast enough even for 4K videos.
The key steps are:
1. Turn the TV USB port to ON so the TV will recognize any USB item plugged in to it. The USB on the RokuTV is meant for a harddrive that has videos and pictures to play from, but when a compatible USB-to-Ethernet adapter is plugged in, the TV will recognize it as wired network.
2. If the TV does not recognize it, Reset the Internet connection in the RokuTV system to refresh it.
Settings -->System-->Advanced-->Network Reset.
What if a wired connection is not an option? You can still improve on the wifi reception by supplanting the device's wimpy internal wifi antenna with a more powerful external antenna. Roku does not sell its own Ethernet-to-USB adapters, but it does sell this external USB-powered wifi transceiver.
Power Cable with Long-range Wi-Fi Receiver
https://www.roku.com/products/accessories/usb-power-cable-with-long-range-wifi-receiver-streaming-stick-4k-and-4k-plus?srsltid=AfmBOoo1ImnLQqJl_6UhC_R99xtcLhdrmpHhvLdUOqBJ75J9QfrkJBdM
The larger end USB (USB-A) plugs into your TV USB port. Because this connection is to power the transceiver, if the TV has a USB port meant for power, use that. You can also plug this USB-A end to an actual USB charger that is used to charge your phone.
The smaller USB end (USB-B) goes into your Roku device. Because this transceiver is made by Roku, the Roku device should automatically detect it and disable its own internal antenna in favor of this external one. With this external transceiver, your Roku streaming device should be able to pick up fainter wifi signal from your wifi router.
This transceiver is compatible with these streaming devices:
Roku Streaming Stick 4K (models 3820X and 3820X2)
Roku Streaming Stick 4K+ (models 3821X and 3821X2)
This makes sense because 4K videos require more data going into the devices, necessitating a more sensitive receiver.

Share YouTube Playlists
If some people, including yourself, rely heavily on Youtube to work on a project or share an interest, everyone can collaborate more efficiently by sharing playlists. Below is the how-to guide to do this.
https://support.google.com/youtube/answer/6109639?hl=en
Needless to say, unless you are members of the same family group, you cannot share private playlists. The shared playlists must be either Unlisted or Public.

Microphone Plug Types
The video below is a good start to get information on a bewildering array of microphones.
https://www.youtube.com/watch?v=K0rCUohAVws
Below is the plug with a 4-hole interface called TA4F aka TQG aka 4-pin mini XLR. The TA4F end would go to a variety of wireless transmitters. Transmitters are devices that you clip onto your belt. They communicate wirelessly to an audio receiver appliance in an AV cabinet. The other end of this adapter is a microdot that is plugged into a microphone. Notice each hole has a number.

Use more than one version of macOS and Windows on same Mac
People can dual boot Windows computers for a long time, including with Linux and Windows. However, Mac users don't know they can do the same with having multiple macOS systems running on the same Mac computer. The process is simple.

Sync Between Apple Photos App and Google Photos App
I should mention first that the backed up files are not physically stored on the GP app on the mobile device. Only thumbnails are stored there to reduce storage consumption on the these mobile devices which by their nature, usually do not have a lot of storage to accommodate hefty-sized media files.
You can delete files from AP and GP.
When you delete a file from AP, this file will not be deleted on GP. This makes sense because GP acts as a backup. Think about it, if you delete the source file, and this action is replicated automatically to the backup copy, the action defeats the purpose of a backup, doesn't it?
By contrast, when you delete a file from GP, be it on the iPhone or iPad or on the GP website, this file is no longer visible on GP because it is marked as "to be deleted" in GP. In 60 days, this file will be automatically and permanently deleted from GP trash.
If you don't want to wait 60 days for this automatic deletion in AP via GP, you can go to the GP app and tell it to empty the trash.

Installing Windows 11 on incompatible PCs
First, make sure you have the following things:
- Windows 11 ISO file, downloaded from Microsoft website
- Windows 10 bootable USB drive of at least 8GB. This is the USB that will install "Windows 10" into the computer where the core Windows 11 payload is encapsulated by the preflight Windows 10 installer.
- Computer running Windows 10 to use to put the core Windows 11 (the wolf) into the Windows 10 (sheep clothing)
- Navigate to the Windows 11 ISO file on the Windows 10 machine.
- Right click on it and choose Mount.
- Open the mounted ISO image and open the sources folder inside.
- Look for the install.wim file, select it, and press Ctrl + C.
- Connect the bootable Windows 10 USB drive to PC and open it.
- Also, find and open the sources folder inside.
- Press Ctrl + V to paste the install.wim file you’ve copied.
- Click Replace the file in the destination in the pop-up dialog window.
- Reboot your computer into BIOS and enter the boot menu.
- Change the boot device order: adjust your bootable USB drive to be the first option.
- Exit BIOS and save changes.
- Your computer will restart and you’ll be asked to select and install a Windows 11 version. Remember, the installer from the USB drive thinks it is installing Windows 10, but it is actually installing Windows 11 because the source wim file is Windows 11.
