So, last night I undertook some surgery, and replaced the motherboard and processor in my old gaming rig with a slightly upgraded combo so that I can squeak in under the minimum specs for Star Citizen. After the bootup, windows started telling me that my copy was no longer licensed.

Now, I had used the free upgrade from win 7 Pro, and as such had a win 10 pro install for the last 3 years or so. All above board. Now, the system is telling me I only have a win 10 home license showing on the system, and that I need to install home to use it.

Why would this happen, and how can I get my win 10 pro license back in good standing on the new hardware? Again, only the motherboard and processor have changed...

EDIT

I ended up purchasing a new license from StackSocial as suggested by pseudolobster below, and the issue is now resolved. Thanks to everyone for all the helpful responses!

I'm attempting to make my company's online software documentation ADA-accessible. We have several JavaScript elements that are currently not accessible to a screen reader. The one I'm working on is a set of tabs that show/hide content depending on which one you click. I am trying to use ARIA tags to make the tabs accessible. I have based my code off of this page, with some modifications. Namely, they use <a> tags as the active element and I do not want to use <a> tags.

While I'm able to get the tabs to work fine for me (a sighted person), testing with a screen reader shows mixed results. I can get the tabs to work using the Windows Narrator screen reader on Microsoft Edge in Windows 10, but not Chrome or Firefox in Windows 11. In those configurations, it is impossible to switch tabs. (I haven't tested every possible permutation, but it's probably a browser issue.) I don't know why this is happening because I have set up all my ARIA tags, and it does work on Edge.

Can anyone help me understand what I'm doing wrong so I can debug the issue and improve the code? Requirements are:

• The first tab must be selected (showing content) by default. Other tab content must be hidden by default, except the tab button to click on
• Sighted users must be able to navigate between tabs by clicking on the tab headers via mouse
• Visually impaired users must be able to navigate between tabs via keyboard/screen reader
• The presence, function, and usage of the tabs must be clear to the screen reader
• I do not want to use an <a> tag nested in the <li> as the active element because this causes the page to jump around when sighted users click on it. I would like the entire "button" (right now, the <li> tag) to be clickable.
• Must work on all/most common browsers and popular operating systems

I suspect this is a JS issue, but I'm at a loss here and I don't know how to proceed.

I used Macrium Reflect to clone a Windows 11 install from one bad SSD to a new one. I had to reinstall to repair the Windows install, but it's a done deal, but I feel burned by Macrium and want to find an alternative.

I was wondering if anybody had any leads on great cloning software for general use? I'm willing to pay money, and it can be online or offline software (in OS or via USB).

I have two drives, a 4TB and 1TB HDDI'm cloning to 4TB SSDs to have on newer devices, since these two are quite old and I got a deal on a pair of Crucial SSDs on Amazon (a brand/line I'm familiar with, they're good drives). These largely have games that aren't installed, legacy data old music rips I want access to, and currently active user profiles.

My goal: clone the partitions over to the new drives, pop them in with hopefully the same drive letters, and expand the partitions to use all free space and be done with it. Ideally I would also have tool I can recommend to others without concern, assuming they have basic computer literacy.

Will CloneZilla do this just fine? Is there anything better, proprietary or otherwise? Any idea how long this can be expected to take over Sata II (I've got a hotswap port I'll be cloning to outside my case, then popping it open to swap the drives).

The end of the year is approaching fast and I still have some educational budget to spend. Therefore I would love to hear your suggestions for educational resources to spend some money on.

I'm open for all suggestions, but I would love to dive more into low level programming. I spend most of my work time as a backend dev. And it is nice for a change to something else than REST-endpoints.
At the beginning of the year, I bought the amazing Crafting Interpreters by Robert Nystrom and I'm enjoying tremendously.

So any recommendations going into the same direction or similar deep dives into topics like OS-dev, Game dev/graphics (tiny renderer comes to my mind) or writing emulators would be appreciated.

To get the discussion started, my top recommendation for his year would be Crafting Interpreters by Robert Nystrom.
If you are interested in the inner workings of interpreter and compilers and want a nice "program-along" book get it. I would recommend the paper-version, it is a beautiful book.

I am asking as I have just created one. I won't advertise it here, as it feels not in good faith and I don't think Tildes is the right audience (I imagine most of the techies here are probably fairly seasoned).

I want to offer some kind of programming tuition to people at a good rate (read: affordable to those that might be on a low income but wish to learn). I am doing this to raise money for my local cardiology ward, who have just been told there isn't enough in the budget to cover their Christmas party this year. Morale is low there, and I'd like to help cover the deficit.

How would you structure something like this?

Initially, I have written that I have no set fee and am happy to offer services on case-by-case basis (words to that effect). But in a discussion with a friend, they suggested I should do something like:

• Small donation (£1 - £25): Access to a chatroom (Discord?) where someone can ask questions, and I'll strive to answer and help them as fast as possible)
• Medium donation (£25 - £50): I will arrange a group session where I cover some basic programming concepts and host a Q&A at the end to help bridge any gaps in understanding.
• Large donation (£50+): I will arrange a one-to-one session (via call, video or instant messaging) where I will help go more in-depth on a topic or help debug a specific problem.

If anyone has any experience with this type of thing, I'd appreciate any advice. I have only been a professional software developer for three years, so I am reasonably experienced, but not exactly an industry veteran. I want to set realistic expectations for this service.

I'm happy to share a link to the open collective via private message if anyone wants to have a look over it and offer any advice.

I'm looking to get a new laptop for when I want to go work at a coffee shop or something.

I have seen the Framework laptops and like the idea of a modular computer you can upgrade or repair.

I'm a little hesitant though. The last laptop I tried was to buy a Pinebook a year or two ago. I got it, turned it on once and it worked fine, but then after that it would just get a black screen when I powered it on. Some posts online indicated that it might be because the memory card wasn't seated properly and it might fix the problem to reseat it. But the tiny screws on the bottom were really tight and I ended up stripping one of them while trying to open it up, so now I just have a laptop I've used once collecting dust.

I want to make sure I have an easier experience with my next computer. Can anyone attest to the reliability of the Framework 13?

I'm a technical writer. My company sells DevOps software mostly operated on the command line. I'm responsible for explaining this software via HTML5 documentation on our website.

One of our largest customers employs at least one software developer who is "totally blind" and requires a screen reader to work. I assume others exist, but they have not contacted us. Unfortunately, our website is not 100% ADA-compliant. It's far from the worst I've seen, but it could be a lot better.

I'm familiar with high-level web accessibility paradigms and am currently doing an informal audit of our website to determine what we need to improve to make it fully ADA-compliant. I've prioritized discovery for accessibility concerns in our next sprint. Eventually, I'd like to look into hiring a consultant to do a more robust analysis, but only if necessary because I'd need to request funding. Unfortunately, I have limited control over the text that displays in our product, just the documentation. Long-term, I'd like to collaborate with the product team to ensure our CLI is fully ADA-compliant.

I've begun reading web accessibility materials from the government. In the meantime, I wanted to ask: are any of you blind or low-vision, or have you used screen readers in the past? Or do you know any blind/low-vision devs? Either way, can you provide any personal insight into any of the things I can do as a technical writer to improve the usability of software documentation for the purpose of enabling you to do your job? My goal is to make the documentation experience great for screen reader users, not just OK.

I'm seeing a lot of news in my feed about Qualcomm chips approaching laptop performance, such as

Will this turn out any better than the last few times Microsoft tried to break away from Intel? Would you want such a laptop? Will it wake Intel out of its complacency?

Would appreciate any pointers or hints from anyone who's tackled this challenge. Thanks in advance!

Hello,

I have quite some technical question and my DuckDuckGo-fu seems very weak on this one. I hope it is ok to post questions on Tildes, as it is not really discussion material... but someone can still learn and use whatever come from this.

I have Live Aid concert that I ripped from my DVDs and I wanted to merge the individual video files (there are four) into one long video. I'm on Linux and I'm used to ffmpeg in command line, though I do not know it that much. Each of the input videos has its own chapters and I would like to transfer those chapters into the final video as well. Preferably adding a chapter in between every input video.

I was unable to find if ffmpeg allows for something like that in a single inline command. I may have to export chapters from each input video and add them into one "chapter" file and redo times by hand on them and then use this file as "chapter" input when merging the videos, but all this is just a theory on my part.

Is there some FFmpeg expert here who has done something like that?

Hey all, I'm interested in going down the rabbit hole with Ubiquiti equipment or other manufacturers, more specifically with access points, routers, and a switch. I want to ween off my ISP-supplied all-in-one equipment as their newer hardware limits basic features such as port forwarding, and I'm interested in re-enabling my self-hosted software. Wi-Fi standards have been moving pretty quickly, as have hardware. What setups do you have established in your homes?

I don't really have a budget in mind, and have a 2.5GbE port I'd like to utilize for media consumption over LAN.

Between "enshittification" and my general admiration for hobbyist websites, I have felt more and more pressed to learn how to make the websites I want to see and offer it at low cost. At the same time, people usually have to maintain their day jobs and development expenses. I am curious how easy or difficult it is for people to do. (Also, I guess please share your small website if you'd like)

Hi everyone,

So, I have a DS923+ with 4GB of RAM and while it is running fine most of the time with my Docker containers, I guess everything could be more fluid (e.g. scrolling on Jellyfin while it is loading info / images).

Since the Linux OS uses free RAM as cache, I was looking to buy an extra stick of RAM. I was thinking of buying a 8GB of RAM which in total my system would then have 12 GB. Not sure if overkill, but still, I run a few containers.

I’ve actually searched on the Synology subreddit, but everyone is basically buying 16GB of RAM or maxing out the GB allowed for the RAM on the DS923+. So, that is the reason why I’m asking here.

I know that Kingston has some 8GB RAM sticks which should work with DS923+ but it seems they are blacklisted by Synology, so it seems you will always have a warning on the notification list which I wanted to avoid. :/ But on that list (see here: Ram list), it seems the 8GB RAM that Synology uses is sourced from Innodisk or Adata, so you shouldn’t get any warning there. Sadly, I can’t find them anywhere for sale. Even when I contacted the companies directly.

In conclusion, has anyone bought a 8GB ECC RAM for the DS923+ which doesn’t give a DSM warning?

Thanks everyone in advance!

Cheers!
