Linux for Windows users

From a FB forum:
If you're looking for a Linux distribution that is most similar to Windows and also fully supports NVIDIA graphics, here are the best options for you:

Zorin OS – Zorin OS is the closest in terms of look and feel to Windows. It offers an interface that resembles Windows 7 and Windows 10, which makes it ideal for users transitioning from Windows. Zorin OS supports NVIDIA graphics well and comes with a tool to easily install the proprietary NVIDIA drivers. It's an excellent choice for those who want a familiar experience with solid NVIDIA support.

Linux Mint (Cinnamon) – Linux Mint is one of the most Windows-like Linux distributions, especially with the Cinnamon desktop environment. It provides a very user-friendly experience and a familiar layout. Mint supports NVIDIA graphics, and the process for installing the proprietary drivers is simple and integrated into the system. This makes it a top choice for users coming from Windows.

Ubuntu – Ubuntu with its default GNOME desktop is a bit different from Windows, but it can be made more Windows-like by installing the Ubuntu MATE or Ubuntu Budgie desktop environments. Ubuntu has strong NVIDIA support, and drivers can be easily installed via the Additional Drivers tool. It's a reliable choice for those who want solid support and a lot of resources.

Pop!_OS – While Pop!_OS, developed by System76, is not exactly Windows-like in appearance, it is extremely user-friendly, especially for users who need high-performance NVIDIA graphics. It offers built-in support for NVIDIA graphics cards and provides automatic installation of the proper drivers. For users who prioritize performance and ease of use with NVIDIA hardware, Pop!_OS is an excellent choice.

Summary:
Zorin OS is the closest to Windows in terms of design and experience while also providing full support for NVIDIA graphics.
Linux Mint (Cinnamon) is another excellent Windows-like option with solid NVIDIA support.
Ubuntu offers good NVIDIA compatibility but is less Windows-like than the other two.
Pop!_OS is perfect for those who need high-performance NVIDIA support, though it may not resemble Windows as much.

Schedule automatic iPhone reboots (sort of ...)

How to Automatically Restart iOS Every Day
https://medium.com/@bjammin/how-to-automatically-restart-ios-every-day-4b3bfdba7a90

"Experts ... say forcibly closing apps could stop criminals from monitoring …
Persistence is difficult on iOS, and restarting it will clean up running processes.

We could use the Reminders app to set a reminder and then go through the process of holding the buttons, swiping, etc. But, there's a better way.
Shortcuts app! We still get a pop-up prompt and still need to be there to hit "Ok." Apple probably doesn't want to allow scheduled restarts because of the risk of a phone turning off in the middle of an emergency. But I'm pretty happy with this one-click approach.

On your iPhone, open the Shortcuts App which should be installed by default. Then:
  •     Tap on the Automation tab
  •     Create Personal Automation (or click the plus if you have some)
  •     Time of Day (or use another trigger)
  •     set your schedule & tap Next
  •     tap Add action
  •     search for shutdown and tap add
  •     Tap the word "Shutdown" and change it to "Restart"
  •     Next
  •     Done"

Workshop / workspace organization tips

On the topic of workshop or workspace organization:
Just a tiny chapter in the Lean Book of Excellence is 5S.
A series of steps to achieve organizational excellence which very few ever attain.  It is not easy - it is time spent up front to lead efficiency ongoing.
So here is what 5S in its simplest terms -

#1 Sort - only keep what is needed. All else removed.

#2 Set - every item has a place where it lives. 
  • All like items in one place. 
  • Label drawers/cabins on the exterior because once you 5S everything you will get really frustrated by not being able to find what you are looking for.

#3 Shine - clean up and use methods for keeping sets/items like hand tools, etc. from rolling around. (foam storyboards, socket trays)

#4 Standardize - If more than one station/workbench, use the same tool -mfg./model - where possible.

#5 Sustain - implement a plan to keep #1 through #4 from dissolving back into the chaos from which it came. Mainly, At the end of the day/project everything is back in its place.

Once done, clutter should be a thing of the past. Zero searching around for that special tool.

How to Play Audio From Multiple Outputs in Windows 11

In testing, this doesn't significantly increase the volume of sound coming through monitor speakers via HDMI, but the sound does seem a bit clearer.  Using the headphone jack to drive proper speakers via a small amplifier is still preferable.

Advancements in synthetic skin could lead to better prosthetics

New Electronic Skin Communicates With the Brain Just Like Your Actual Skin (from FB):
A team of engineers at Stanford University has created a revolutionary soft electronic skin that communicates directly with the brain, mimicking the function of natural nerve signals.
Unlike previous iterations that rely on external devices, this next-gen e-skin senses temperature and pressure, converting them into electrical impulses similar to those sent by human nerve endings.
This innovation follows other cutting-edge projects, like a spray-on skin for gesture recognition and a smart bandage that monitors wound healing. Engineers at MIT and Graz University of Technology are also pushing the boundaries with sweat-proof e-skins and hybrid materials that detect temperature, moisture, and pressure.
The Stanford e-skin is made up of layers just nanometers thick, using materials like the rubber found in surgical gloves. The final product, supported by a substrate to maintain durability, is as thin as a sheet of paper. Operating at just 5 volts, the e-skin offers safe, sensitive feedback—potentially transforming prosthetics by providing a realistic sense of touch. Future goals include wirelessly transmitting these sensory signals to chips embedded in the nervous system, allowing prosthetic users to move their limbs naturally. With ongoing research focused on enhancing these capabilities, the Stanford team is inching closer to making human-prosthetic integration a reality.

US Special Forces Rifles

It appears that rifles developed in the 1980s, firing cartridges developed nearly a century ago are still what our Special Forces need.

One reason for keeping the large 50 caliber round is that it has enough room to fit explosives or incendiaries when they would be most effective.
https://www.globalsecurity.org/military/systems/munitions/mk211.htm

There is (always) some talk of moving to a smaller round.  A bullet doesn't need to be a specific diameter to hit a target with sufficient energy to destroy it.  Also, cartridge cases can get smaller as propellants get more powerful and gun metals get stronger.  Small lighter cartridges make it easier to carry more rounds, but they need to be as effective (or more so) than the ones they're replacing.  This article is about different military rounds, but it makes the point:
https://www.pewpewtactical.com/7-62-nato-vs-5-56-nato/

I find it interesting that the current Barrett 50 caliber used by our troops is semi-automatic.  In civilian distance competitions, Barrett's bolt-action rifles in the same caliber are more accurate.  Perhaps the rate of fire (and the demands of urban combat) is nearly as important as it's accuracy in current combat scenarios.

DVD Drives Turned Into Microscopes


" This build requires two DVD pickups. By scanning once horizontally and once vertically and measuring the returning light from the DVD laser, an image can be created. For this build, the second pickup is used to move the object itself. The entire device is controlled by an Analog Discovery 2, although this principle could be ported to other microcontroller platforms. Thanks to the extremely fine laser in a DVD and the precise movements of the motors found in the control machinery, the images obtained using this method have the potential to be more detailed than comparable visible light microscopes.
While this isn't quite scanning electron microscope territory, it's good enough to clearly image the internal workings of a de-capped integrated circuit."

Night Vision in a Vehicle: Is It Worth It? (July, 2022)  

Night Vision for Your Car or Truck:  (Amazon search: "night vision camera for cars." )
https://www.autoweek.com/car-life/diy/a31936162/want-night-vision-for-your-car-or-truck-there-are-options-at-every-price-point/
"Unlike night vision on Cadillacs and BMWs, the Lanmodo (https://www.lanmodo.com/lanmodo-1080p-automotive-night-vision-system.html) unit is not infrared. It takes whatever light is left out there once the sun goes down and sort of multiplies it on the little screen. I was amazed at what it could see.
...
And while those infrared cameras see only in black and white, the Lanmodo broadcast in beautiful color."

"Anyway, night vision stuff is fun, but to be really useful, in my opinion, you would need to incorporate the large animal warning software offered by many carmakers. So yes, it looks like you're gonna have to buy that Cadillac." or BMW, Mercedes, etc.

"Messaging vs. calling -
When you travel or go on outside adventures, having a fully loaded SAT phone may not be necessary. Opting for a more basic satellite communication solution also means saving money. 
You've already got a smartphone—what you need is another layer of communication safety outside the cell phone zone. 
If you want to keep it simple, consider a satellite GPS messenger. These devices allow you to send messages to family and friends, letting them know you are safe, and also have important extra safety features like GPS location and SOS signals."

Emergency SOS via satellite -  Apple's iPhone safety feature:
    https://www.pocket-lint.com/apple-emergency-sos-via-satellite-iphone-features-explained/
  • "Apple introduced Emergency SOS via satellite on the iPhone 14 and 15 models, allowing users to contact emergency services in areas without reception.
  •  This feature is for emergencies only and cannot be used for calls or other purposes. It will be routed to the appropriate emergency services or the AAA for roadside assistance.
  • Satellite coverage is required to use Emergency SOS via satellite, and users will be guided through the process of sending an emergency text."
  • "This is a messaging system - you can't use it to place calls or anything else - it's for emergencies only and will be routed through to the appropriate emergency services, or the AAA for roadside assistance."
  • " The service was only available in the US and Canada at launch. This includes Puerto Rico and the US Virgin Islands, but not Guam or American Samoa.
  • It expanded to the UK, Ireland, France and Germany in December 2022, and then to Australia and New Zealand in April 2023, and by the end of 2023 the list will also include Austria, Belgium, Italy, Luxembourg, Netherlands, Portugal, Spain, and Switzerland.
  • ... However, the roadside assistance part of Emergency SOS is currently US-only, since it's in tight partnership with the AAA."

If you see SOS, No Service, or Searching on your iPhone or iPad:

Use Emergency SOS on your iPhone - With Emergency SOS, you can quickly and easily call for help and alert your emergency contacts:  https://support.apple.com/en-us/104992
"When you make a call with SOS, your iPhone automatically calls the local emergency number and shares your location information with emergency services1. In some countries and regions, you might need to choose the service that you need.
...
On iPhone 14 or later (all models), you can even use Emergency SOS via satellite to text emergency services when no cellular and Wi-Fi coverage is available."

Iomega Zip drives

Still handy today for small files if you don't want to use USB sticks:
https://en.wikipedia.org/wiki/Zip_drive
" Zip disks must be used in a drive with an equal or greater storage capacity. Higher-capacity drives can read lower-capacity media. The 250 MB drive writes much more slowly to 100 MB disks than the 100 MB drive,... They can be formatted in any version of Windows as normal... The 750 MB drive has read-only support for 100 MB disks."
" Sales of Zip drives and disks declined steadily from 1999 to 2003.[10] Zip disks had a relatively high cost per megabyte compared to the falling costs of then-new CD-R and CD-RW discs."
"... during their prime, Zip disks greatly eased the exchange of files that were too big to fit into a standard 3+12-inch floppy or an email attachment, and there was no high-speed connection to transfer the file to the recipient."

Swiss Micros calculators - updated HP clones with RPN

These get great reviews on FB's HP RPN site (https://www.facebook.com/groups/hpcalc/):

" The DM16L is the programmer's calculator designed to display and work with numbers in hexadecimal, decimal, octal and binary, and convert numbers from one base to another. A number of specialized functions are provided to assist the programmer, including left- and right-shifting, masking, and bitwise logical operations."  https://www.swissmicros.com/product/dm16l
CHF (Swiss Franc) 149 = about $175
Console Mode: " Once the serial connection to the calculator is established, calculator responds to switching to Serial Console Mode..."
" The USB connection features a command line interface for saving and restoring complete calculator states.
Firmware update via USB is possible using the SwissMicros Firmware Update Tool (on Windows) or standard lpc21isp utility on Linux and MacOS."
Uses RPN - "The Hewlett-Packard Voyager series of calculators were introduced by Hewlett-Packard in 1981.[4] All members of this series are programmable, use Reverse Polish Notation, and feature continuous memory. Nearly identical in appearance, each model provided different capabilities and was aimed at different user markets." 
" HP-16C – computer programmer's calculator (1982–1989)."
" The HP Voyager series calculators are keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional branching and looping instructions, allowing programs to perform repetitive operations and make decisions."

From FB: " They are slightly different beasts. The DM41X runs the original HP-41CX ROM code on emulated hardware while the DM42 runs the "Free42" software emulator on the native hardware. The DM41X is much faster than an original HP-41CX, but the DM42 is way, way faster than the DM41X. For comparison, the DM41X takes 407s to solve the "N Queens" problem on a 7x7 board; the DM42 solves it in 16s on battery power, and 6.8s on USB power."

"The DM42, one of our flagship line-up of RPN calculators, is a true homage to the legendary HP-42S, widely regarded as one of the most desired calculators ever made. The DM42 is the most precise calculator on the worldwide market - second to none - and uses the powerful and proven RPN logic. The DM42 runs Free42, based on a decimal floating-point math library and IEEE 754-2008 quadruple precision decimal floating-point, encoding numbers in 16 bytes and giving 34 decimal places of precision with exponents ranging from -6143 to +6144."

"The DM41X, another member of our flagship line-up of RPN calculators, is a faithful recreation of the software environment of the HP-41CX, one of the most versatile calculators ever created and the first alphanumerical calculator, in a modern hardware architecture. Easily share or back up your programs or your entire DM41X environment and use hundreds of existing, professionally developed software applications with this rugged calculator sporting a stainless steel case and a Gorilla Glass screen.Like all SwissMicros calculators, the DM41X uses the efficient and time-tested RPN logic."

Can I Get Sound Notifications on Both iPhone & Apple Watch

How to Get Sound Notifications on Both iPhone and Apple Watch:
https://techwiser.com/how-to-get-sound-notifications-on-both-iphone-and-apple-watch/
"If your iPhone is unlocked, your notifications will arrive on the iPhone itself and will not go to the Watch. It makes sense because if you are using the iPhone, you should be able to see the notifications on the phone itself. You shouldn't have to look at your watch to check the notifications.
...
On the other hand, if your iPhone is locked, which indicates that you are not using your phone, the notifications will arrive on the Apple Watch provided it is unlocked.
...
But the problem arises when a user wants notifications to arrive on both the devices i.e., Apple Watch and iPhone. You may ask, why? Well, every user has different reasons. The primary reason being the sound of the notification is louder on the iPhone than on the Watch.

Sadly, Apple doesn't provide any direct setting to achieve this behavior. However, there's a workaround that lets you get notifications on both Apple Watch and iPhone."
"To get notifications on both Apple Watch and iPhone, you need to turn off the wrist detection feature. Unfortunately, you will have to sacrifice certain things after you turn off wrist detection:
  •     Heart rate tracking and it's notifications are turned off.
  •     Your watch will not lock or unlock automatically.
  •     You will have to enter the passcode to authorize payments using Apple Watch.
  •     Emergency calls will not be made in case of fall detection.
  •     Some other activity measurements could also stop working."

---------------------------------------------------------------------------------------------

"... by design, when using an iPhone that is locked, it will route all text messages notification alerts to the iWatch.  If the phone is unlocked it will not."
"You can turn off Apple Watch notifications and then get all your notifications on the iPhone by using the iPhone "Watch" app -> Messages -> Notifications Off"

"You can send Apple Watch Feedback and ask for a feature change
Https://www.apple.com/feedback/watch.html
They will not reply, but it does get read."

"     If the watch is on silent (which it can be if the phone has been switched to silent during the day, the watch stays on silent) you don't get anything.

On your phone, go to the Watch app. Go to General>Do Not Disturb>Mirror iPhone and turn it off. That way, your watch will not get switched to silent when your phone is. Also, go to Sounds & Haptics. Make sure that Haptic Alerts are enabled and that you have ticked "Prominent'. "

Transfer Photos from iPhone to Windows 11

How to Transfer Photos from iPhone to Windows 11:
https://www.howtogeek.com/765820/how-to-quickly-transfer-photos-from-iphone-to-windows-11/
"right-click your iPhone in File Explorer and select "Import" to import them automatically."
"After Windows has found all the new photos and videos it hasn't imported before, it will show you how many can be imported.
If you want to experiment with Windows 11's (somewhat confusing) attempt to organize your photos, you can choose the "Review, organize, and group items to import option." However, we recommend doing a simple import: Select "Import all new items now," then click the "Import" button."
"If you'd like to erase all the photos and videos from your iPhone after you're done importing, place a checkmark beside "Erase After Importing.""
"Open a File Explorer window and navigate to your Pictures folder. In that folder, you'll find a dated folder that contains all the photos and videos that you just imported."
"If you notice a bunch of AAE files in the folder with the pictures, don't be alarmed. Those are special metadata files Apple uses to store photo editing info. They are useless on Windows, so it's safe to delete any .AAE files you find."

WordStar 7, the last ever DOS version, is re-released for free

"The preferred tool of Arthur C Clarke, Anne Rice and George R R Martin":

" Sawyer has taken the final release, packaged it up along with some useful tools — including DOS emulators for modern Windows – and shared the result."

" The download is 680MB, but as well as the app itself, full documentation, and some tools to help translate WordStar documents to more modern formats, it also includes copies of two FOSS tools that will let you run this MS-DOS application on modern Windows: DOSbox-X and vDosPlus. Regular Register readers may recognize both from our story on how to run DOS on a 64-bit OS from last year. Sawyer also offers a handy command reference [PDF]."

" While it certainly has been abandoned since the end of the 20th century, the term "abandonware" isn't a legal one. It's not clear to us who owns the intellectual property. We doubt it's one of the surviving offshoots, today's Houghton Mifflin Harcourt, but it could be another offshoot, Software MacKiev. Either way, it's very unlikely that the owners will care."

Door Locks, Digital Entry Locks, and other home security devices

For escape from a courtyard where the door and the gate are locked:

First, the simplest & least expensive solution is to fasten a pushbutton key safe somewhere inside the courtyard and install conventional locks on the doors:

http://www.amazon.com/AccessPoint-Original-Slimline-Pushbutton-Combination/dp/B000GTQU22/ref=sr_1_1?s=hi&ie=UTF8&qid=1338987189&sr=1-1

 

To avoid being locked out, install knob or lever locks that either don't have a key, or a knob lock that unlocks when you turn the inside handle. 

  • I almost never install key locking knobs/levers under a deadbolt anymore. One less keyhole to mess with when in a hurry, they have no security anyway, and harder to get locked out. 
  • Non locking is called a passage function (or hallway/closet lock). 
  • A keyed lever that unlocks when you turn the inside handle is called "push button locking" as opposed to "turn button locking". The ANSI designation is F82.

Regarding digital entry locks, I have never seen a residential one with a keypad on both sides, or a double cylinder deadbolt with a keypad. There is one commercial double keypad, Trilogy by Alarm Lock. Pure Junk ...

 

Most of the residential keypad units are also not well designed and succumb quickly to a variety of attacks all of which can be found on the internet. I would stay away from the Kwikset, Weiser, & Master. 

 

If you really want double cylinder deadbolts AND keypad control, you will need to go to a commercial solution with either an electrified mortise lock for the deadbolt, or a standard deadbolt and a special electric strike on the frame. Probably $1,000 per door installed.

 

What I use at home is Schlage. I have the Schlage Link (Now rebranded as Nexia).  You can get digital entry handles or deadbolts, cameras, an energy management thermostat, and other sensors all on a Z-Wave network

A Nexia Bridge connects to your router to allow you to control your home through a broadband Internet connection. It communicates wirelessly with many other Nexia-compatible Z-Wave products so that you have complete control over your home, whether you're at home or away. 

You can control the system via iPhone or a web browser and an annual subscription fee is charged, about $100.00.  You can set schedules, scenes, events, view the cameras, unlock a door, change the temperature, etc. 

 

Regarding keylocks, my short answer is Schlage, however the sliding door my be problematic. I need to see a picture & dimensions, especially of any existing lock that was provided.


STAY AWAY from the so called "Smart Key" products that allow you to rekey the lock yourself. There are some very well known attacks. 

For example, on the Kwikset, cut a key to all #4 cuts, and using a vise grip, insert the key and turn. The lock breaks and opens. 

Schlage had a similar product, but to their credit, removed it quickly from the market. Not so with Kwikset. 

With key locks, you get what you pay for. Good locks cost more.

Democrats want their president to have more executive power, but not Trump (or any Republican)


"This Supreme Court term has been an absolutely stellar one for those who like the idea of the federal bureaucracy being restrained. It was also a big one for Donald Trump - not only did he win in the Fischer case, but he walked away from his own immunity case with more guaranteed immunity than I think even he was expecting.
This term's cases showed a conservative majority (and, at times, a coalition majority) that laws are being too broadly interpreted. The federal agencies of the executive branch are interpreting too much power from laws that are too vaguely written by the lawmakers of the legislative branch. As a result, our laws and regulations are being wielded with reckless disregard for the common man."

"But their frustration over the immunity case is directly at odds with their frustration over the Chevron case and others. They are torn between their love of executive branch power and their hatred of a potential Trump as the leader of the executive branch. ...
Their chief complaint about the immunity case is that it would grant Trump too much power as president. But their chief complaint about several of the other cases is that it takes away too much power from the executive branch."

"The immunity decision is much more narrow than the Democrats will honestly admit. The majority was clear in its ruling - absolute immunity extends only to official acts as president. In other words, if it isn't a power granted to the president via the Constitution or by Congress, then it isn't covered in the Supreme Court's decision.
So, with all due respect to Sonia Sotomayor, it's foolish to claim that Trump could arbitrarily assassinate political opponents and be covered by presidential immunity."
If that power existed, then the current president (Biden) could have Trump assassinated ...

"What the Supreme Court did in those cases restricted Trump from far more power than he gained in the immunity ruling because those agencies are within the scope of his office."

"The Democrats aren't mad because they think the rulings are bad. They do think that, but their anger is more over the fact that they are struggling to jail Trump before the election (that's been their strategy for beating Trump from Day 1) and the fact that they don't actually want the legislative branch to have to do work. They would rather Congress serve as a bunch of ideological figureheads while the executive branch does all the heavy lifting.

Mossberg 500 Persuader & Cruiser Reviews

Mossberg 500 Persuader & Cruiser | Gun Review:
https://athlonoutdoors.com/article/mossberg-500-persuader-gun-review/

Some folks rely on the distinctive "shuck-shuck" sound a pump gun makes as a deterrent.  My instructors advised trying hard to make no sounds until the gun goes bang if the situation warrants that.  Either way, a 12-guage pump shotgun is a powerful tool to end home invasions.

"Pump guns are noted for their reliability. You can depend on a manually operated pump, which is comforting when lives are on the line. In the unlikely event of a misfire, cycling the slide will quickly have you back in business."
"No other type of weapon has a longer record of proven battlefield success."
"The Mossberg 500 Persuader sports a conventional buttstock with a recoil pad. The pump-action forend on the test gun has an integral tactical light that throws a bright, high-intensity beam when the rubber insert on either side of the forend is squeezed. This L3 light from Insight Technology produces a tungsten-halogen beam rated at 125 peak lumens, with a battery life of 90 minutes of continuous operation. The L3 features a "temporarily on," a "temporarily off" and a "strobe" setting, and is operated by an ambidextrous pressure pad on either side of the slide handle.
...
The light is bright enough to temporarily blind your assailant, while giving you a clear picture of who's facing you and where to aim. If you feel you're in imminent danger and must shoot, the shotgun eliminates the need to "double-tap," or fire a pair of closely spaced shells, as you would with a handgun."
"The Persuader's 18.5-inch barrel gives the gun an overall length of just 38.5 inches, making it easy to swing in the confines of any room in your house. If you want something even more compact, the Cruiser, which comes with a pistol grip, measures just 31 inches overall. This length comes in handy for carrying the gun in your car or a truck and is ideal when there's little room to deploy a full-length shotgun."
"A tab on the left side of the receiver and to the rear of the trigger allows you to cycle the action to remove a loaded shell from the chamber. This tab also serves as a loaded chamber indicator—if the full-length of the tab is visible, the action is loaded, cocked and ready to fire. If the tab is retracted into the action, the chamber is empty."
"The receiver is drilled and tapped to allow mounting a scope or adding a Picatinny rail. A variety of sighting options are available, including ghost-ring aperture sights, laser sights and virtually any optic that fits a Picatinny rail. Both the Persuader and Cruiser shotguns come standard with a white-dot front bead."
NOTE: according to MidwayUSA, these models have been discontinued, but the Model 500 is still available in many variations.

You can convert any Mossberg shotgun (and other popular shotguns) with an 18.5" barrel and a weapon light like the Streamlight TL Racker Weapon Light:

Build an your own cheap NAS (Network Attached Storage)

How cheap can you build a NAS (Network Attached Storage)?
https://www.xda-developers.com/how-cheap-can-you-build-a-nas/
"All you need to ensure is that you have SATA slots for your HDDs  ..."

How to turn an old PC into a NAS:  https://www.xda-developers.com/how-turn-old-pc-into-nas/
"Any old desktop PC will do, but the better the hardware the more capabilities you have."
"Plenty of people use old Raspberry Pis for media streaming without transcoding and with a hard drive attached for data storage."

"For a NAS, you'll want to pick up specialized NAS drives, but that's all ...
You'll just need to have enough SATA connections on your motherboard and space for the drives inside your computer.
If your PC has things like a DVD reader, you can even buy adapters from the 5.25-inch slots desktops typically use to get them to fit a 3.5-inch SATA drive."
"It could be good to also pick up an SSD for booting from. This doesn't have to be large, and in most cases, a 64GB SSD is more than enough. You can get a larger one and partition it if you'd like to use the secondary partition for caching, but you don't need to and you'll be completely fine without it."

"TrueNAS Core is technically more supported than TrueNAS Scale, and it's based on FreeBSD. Most people would prefer Scale for running actual apps, so if you want your NAS to be more than just storage, you probably don't want to go with Core unless you're comfortable doing some advanced tinkering. Core is very stable with wider documentation and longer support, but Scale will typically be easier, especially if you already know your way around Linux."

"TrueNAS Scale is a Debian-based (so, Linux) OS that you can install on a NAS, and it manages your Docker containers using Kubernetes. Containers are how you run most programs on a NAS, where a container is essentially an isolated digital island for an application to run in. To allow it to connect to other containers on the machine and to share data, you build "bridges" between these islands by allowing them to directly connect to each other. Containers are naturally isolated, which is great for security and means that applications only share the data that you let them share."

"OpenMediaVault looks dated, but it's very functional. You're not locked into using the ZFS file system meaning that there's a lot of flexibility in adding and changing drives around, and there's also no real hardware requirements. OpenMediaVault can run on a Raspberry Pi if you want it to, and it's a lot more straightforward and to the point in its UI. I find myself sometimes clicking around in TrueNAS to find options for things in a sea of menus, whereas OpenMediaVault is a lot more deliberate. It's different software for different people, but it's worth checking out too."

TrueNAS operating system:  https://www.truenas.com/
TrueNAS CORE Minimum Requirements -
64-Bit CPU | 8 GB RAM (16 GB Recommended) | 16 GB Boot Drive (SSD Encouraged) | At Least One Attached Disk | Network Port | Hardware RAID Not Recommended
https://www.truenas.com/truenas-core/
https://www.truenas.com/download-truenas-core/

Best hard drives for NAS:  https://www.xda-developers.com/best-nas-hard-drive/
Look for Western Digital WD Purple drives for under $100 ... some of the old 2Tb versions are available for less than $50.
"Alternatively, you can go for the affordable Seagate BarraCuda 1TB hard drive. While it lacks the high reliability or better storage capacity of the other drives on this list, it's an inexpensive option if you plan to use your NAS as a media server.
That said, if you're planning to outfit your PC with a quick and snappy storage drive, it's better to invest in a high-speed SSD instead. From ultra-fast PCIe SSDs to easy-to-carry external SSDs, there's quite a lot to choose from, too."

"...a great Google Photos alternative: Nextcloud. Nextcloud is a self-hosted cloud storage provider that you can access and automatically synchronize from multiple devices. I have all of my photos that I capture on my smartphone automatically back up to my Nextcloud instance, meaning I can then access those photos anywhere else really easily as well."

"Jellyfin is similar to Plex except that it's free and completely open source, but you can self host your own media with it. For example, if you have a lot of ripped DVDs and TV shows (I do), then you can host these and stream them to your devices in your home. There are a ton of automations you can set up with Jellyfin and many different applications that you can install to work with it, so be sure to do some digging into this one if you're interested."

How to turn an old PC into a NAS server:  
https://www.nasmaster.com/how-to-turn-an-old-pc-into-a-nas-server/

"An old PC is a perfect candidate for recycling into a NAS."
"A NAS is run continuously like a server. I recommend Seagate IronWolf or Western Digital Red (Plus) drives for NAS enclosures."

"Running a NAS is a great way to save money on subscription services. Have an active account with Spotify, Netflix, and Google Drive? Cancel them all and run everything from your single NAS server. This will cost a considerable upfront sum of money but will save you much more in the long term. Plex Media Server can catalog all your photos, movies, music, and shows for streaming to almost any device.

Then there's the potential for hosting websites from the server. Play Minecraft or some other online games with custom server support? That's possible too! Then there's security with some surveillance system apps on your old PC-turned-NAS. Last, you can use the NAS for storing data such as backups."

"It's possible to run a NAS with your existing copy of Windows. This is an OS you're perhaps most familiar with and it's good to go if already installed. Some issues with a desktop OS such as Windows are unnecessary bloat running in the background, slowing the NAS down, and Windows does not support RAID.

Luckily, there are a few server environments available without paying a penny! One of the most popular is OpenMediaVault. It may not have the flashiest user interface, but this robust OS has excellent hardware support and is incredibly easy to use. Another great OS is Unraid, which acts differently and more as just a bunch of disks (JBOD).
What is openmediavault (Free, Open Source)? https://www.openmediavault.org/
Unraid ($49, free trial) - a powerful, easy-to-use OS for servers & NAS: https://unraid.net/
"Unraid OS lets you use what you have to build what you want."
"Mix and match hard drives of any size to build your server and grow your storage capacity."

Finally, there's TrueNAS CORE. This is another free server environment that offers excellent performance and reliability. It's geared toward those with advanced knowledge and experience but can be mastered in a few hours with handy guides if you're building your first DIY NAS. TrueNAS SCALE is the better option for running apps."

Best NAS drives 2024: Reliable HDD, SSD, and M.2 cache: https://www.nasmaster.com/best-nas-drives/
"The best NAS drive would be one that's specifically designed for use in servers. You could go all-out and pay big bucks for enterprise-grade drives, but manufacturers including Seagate and Western Digital have NAS-specific HDDs and SSDs. Just don't go and use your old desktop PC drives."

"We'd usually not recommend an SSD for NAS storage since it's not the best choice due to how flash storage degrades over time through use. Mechanical drives are better overall and don't have a finite amount of data that can be written."

How to Turn a Raspberry Pi Into a NAS for Whole-Home File Sharing:
https://www.pcmag.com/how-to/how-to-turn-a-raspberry-pi-into-a-nas-for-whole-home-file-sharing
"... a standard external drive will do the trick in most cases. However, since the Pi may not be able to supply enough power to all your drives, you may need one that plugs into the wall or a powered USB hub. If you want a cleaner setup, you can use an internal drive designed for network attached storage, but that would require a big enough case."
"A NAS-Friendly Case (optional): If you want your system to have a clean look, it may behoove you to get an enclosure that fits your Pi and connected drives. This will also help to organize the mess of wires and cables this project will create."

"Start by installing Raspbian with the recommended software as described in our beginner's guide (https://www.pcmag.com/how-to/beginners-guide-how-to-get-started-with-raspberry-pi#:~:text=How%20to%20Install%20an%20Operating%20System%20on%20an%20SD%20Card)."

"If you prefer, you can SSH into your Pi and perform these commands from another PC."
