As someone else suggested, there are plenty of kde apps that could use some devs.
Kde plasma multi-monitor support could also use some love, though its much better than it was a year ago.
I know that mobile linux could definately use more devs, if you want to stretch the meaning of desktop 😁. Kde plasma mobile specifically needs help porting their stuff to qt6 for the up coming plasma 6 release.
They are decommisioned datacenter drives, this could be for a variety of reasons (including errors). There are many discussions online about them wiping smart data.
It depends on your use case, I have a few of their drives in a nas specifically for media. I received one bad drive that failed my burn in tests, which they exchange without issue. All of my important files are stored on a seporate ssd based store.
Serverpartdeals is good.
https://www.goharddrive.com/ is another option. Generally slightly more expensive than serverpartdeals, but with better warranty.
Both are reputable options
I'm using US Mobile. You can choose between using their GSM network (T-Mobile) or their CDMA network (Verizon). Their prices are fantastic and it's all prepaid, so you can limit how much personal information you give them. They've worked out a deal with Verizon so your data isn't deprioratized even though you're not a primary Verizon customer, so there's no speed penalty. I've been very happy with them
Opnsense has an arguably better UI, and more frequent updates.
You can look into the drama about the pfsense devs when opnsource forked it but the tldr is the pfsense devs were openly hostile in a variety of unprofessional and uncalled for ways to opnsense.
More recently, pfsense devs rushed the wire guard integration which turned out to be so problematic that the wire guard devs had to publicly comment that it shouldn't be included inorder to prevent it from shipping. One of the reasons why opnsense forked a few years prior was due to bad code quality of pfsense.
Also my two cents, if you're going to create this list to benefit the community and you don't want to include too many options, then you'll need to make informed decisions on which projects to include and why. Relying on the community is fine, and crowed sourcing knowledge is powerful, but don't ignore large projects without researching them
If you're insane this company makes hardware keys that you can implant under your skin and read via nfc https://dangerousthings.com/product/apex-flex/
(There is also a ring version if for some reason you don't want to shove a microchip inside you 🫣)
