The shopping links may not contain the best or cheapest sources of information and gear, just places I happened to run into while looking for something. I haven't completely checked out and cannot vouch for any of these links. Some of this is specific to the D.C. Metropolitan area or the University of Maryland. A lot is not up to date.

Clonezilla Live My favorite disk backup tool for Linux and Windows.
Fast and Free. Not very user friendly, but stops on error, and runs under user control - extremely important. (Tools that continue after an error, and/or do automated backups to a permanently mounted drive, are mostly useless, because if a source or destination drive starts to fail, or if you are infected by a virus, the new (bad) backups overwrite the old (good) backups. Likewise, Microsoft Windows backup is too complicated to use, because of microsoft adds too many copy protection features - most people don't succeed in creating a usable backup.)
You should only run backups to a removable drive that you remove when not doing a back-up, under your control, and after doing a "chkdsk/b :" (under a cmdshell run with administrative privilidges) on all source drives (for NTFS drives), or run fsck on linux partitions, or backups may not be recoverable. (Once in a while, and before your first backup, you may also want to run chkdsk/b on your destination drive.) If Clonezilla still fails with an I/O error, despite this, you can go into expert mode, and try the -rescue and -z6 (lzip) options. Old Clonezilla fails on Windows 8 and Windows 10, but it is possible new haved fixed this - or at least I see people used it.
Clonezilla is sometimes used to Clone hard drives as well as back them up - but beware that Microsoft doesn't approve of multiple PCs running the same licensed copy of Windows. It may also not work.

Zone Alarm from Zone Labs I don't use this anymore, because it slowed everything down. Windows Security Essentials is mostly sufficient, if kept up to date, and you regularly use Windows Update.

PCMag: The Best VPN Services of 2017
U.S. ISPs can legally resell info about everything you do over the Internet to anyone - and they do. In addition, WiFi and most shared communication lines (such as are used for Internet) are easily intercepted, and any website can be spoofed to fool your browser into making you reveal your accounts and passwords. So using a VPN (Virtual Private Network), which encrypts the data, is often a good idea - if you trust the VPN service. (Since free VPN services must sell such info to make a profit, they probably can't be trusted.) Though a VPN may not stop anyone, like a government, willing to devote sufficient resources, from monitoring your activities (e.g., hiding your IP address and location may not work), so don't do anything illegal. Also, VPNs, like most things that rely on encryption, may not provide long-term privacy - in the long term, most secret codes can be broken, so intercepted data can be saved for future decryption. Yes, I'm being paranoid, but it is a well thought out paranoia. ☺

I tried two well rated VPN services, PureVPN and NordVPN. I had trouble accessing Yahoo and Google search engines and email, as well as video streaming services, and initially couldn't see PureVPN's own web page from PureVPN's own VPN server. But PureVPN tech support was very helpful, and found me (temporary) work arounds. They explained that many websites blacklist published VPN server IP addresses, which means they all work for a very limited period of time. So, while VPNs do help safeguard passwords, you should expect frequent unreliability when using commercial VPN services to access 3rd party servers. In addition, using a common VPN while logging in to gmail may be impossible, because they verify your IP address - unless you set up 2-step verification (e.g., verify you are you through a phone call - which won't work if you use Google Voice). (PureVPN suggested to always use the same VPN server IP address with gmail - maybe that would work.) The only reliable way to make a VPN work with 3rd party servers is to set up your own server, and not publish its existence. Some companies set up their own VPNs so their employees can access their own internal workplace networks. (Though, that can be a bad idea, if employees trust it too much, and ignore security.) Furthermore, VPNs usually slow down network access, and some ISPs deliberately slow down VPN and other proxy data.
PureVPN A well-rated relatively cheap VPN service, which I use.
NordVPN Another well rated VPN service that I tried.

Shopping, general

Caution I've recently had bad experiences ordering stuff from China. All the sellers had 97%+ positive feedback from eBay. Many others now tell me that you should only buy from 99.6%+ positive feedback sellers listed by eBay as top rated sellers - and read all the negative feedback. If anyone says they didn't get what they ordered, or that the seller delayed and delayed, or told them not to give a negative review, or had bad English - stay away from them. Make sure they have been selling through eBay for a few years, with 10,000 or more sales. Oddly enough, this didn't used to be true. I wish the Chinese government regulated merchants more carefully.

Kodi A free IPTV streaming app - the leading platform for Internet Television
Note: You can find many "Kodi" or "Android TV" boxes on-line at eBay or Amazon, that can be used to watch TV and movies from various sources over the Internet, without a PC. From experience, many are fake or don't work - I suggest you restrict yourself to orders from top rated sellers from your own country. AFAIK, this link, only contains stuff that is legal in the U.S. and most countries.
Kodi Wiki Manual e.g., includes list of supported devices
Kodi Wiki: HOW-TO:Modify the video cache so audio and video don't stutter (i.e., start and stop).
  Example of advancedsettings.xml for Kodi 17, assuming lots of (flash-based) memory available. Also turns off flash image to speed kodi start-up. Goes in a directory named something like kodi/Userdata or .kodi/userdata.
GeeXboX - a small (can even boot from a CD or jump drive), very fast operating system that can run Kodi. I tried this because Kodi on a windows PC running on a (slow) Atom CPU kept stuttering despite using the above advancedsettings.xml
