  • I hate how bloated the kernel is. I’d like it to fit into main memory.

    Take a copy of lspci, lsusb. Use them to build a kernel from source with only the bits you need and then make the bits you might need modules. Include your filesystem driver into the kernel and you can skip the usual initramfs stage and jump straight to your root filesystem.

    Might take a few tries, but at least it doesn’t take 18 hours to compile the kernel anymore…


  • You need silicon.

    The earth’s crust is about 25 percent silicon. Sand made out of quartz like desert sand is about 50 percent silicon. Beach sand is usually mainly calcium carbonate from shells and it doesn’t contain much silicon at all. Volcanic beach sand is more likely the same as the earth’s crust so 25-50 percent.

    So as long as you refine your sand/gravel/rocks/lava so that you’re left with pretty much pure silicon, you’re good to go.





  • i like how the answers are the exact same generic unhelpful drivel you hear 20k times a month if you’re…

    Searching for a solution to any problem on the internet.

    There are a million ad- laden sites that, in answer to a technical question about your PC, suggest that you run antivirus, system file checker, oh and then just format and reinstall your operating system. That is also 90 percent of the answers coming from “Microsoft volunteer support engineers” on Microsoft’s own support forums as well, just please like and upvote their answer if it helps you.

    There are a million Instagram and tiktok videos showing obvious trivial, shitty, solutions to everyday problems as if they are revealing the secrets of the universe while they’re glueing bottle tops and scraps of car tires together to make a television remote holder.

    There are a trillion posts on Reddit from trolls and shitheads just doing it for teh lulz and Google is happily slurping this entire torrent of shit down and trying to regurgitate it as advice with no human oversight.

    I reckon their search business has about two years left at this rate before the general public regards them as a joke.

    Edit: and the shittification of the internet has all been Google’s doing. The need for sites to get higher up in Google’s PageRank™ or be forever invisible has absolutely ruined it. The torrent of garbage now needed to ensure that various algorithms favour your content has fucked it for everyone. Good job, Google.


  • I work in OT. The number of “best practice” IT mantras that companies mindlessly pick up and then slavishly follow to the detriment of their mainly-OT business is alarming.

    Make your own damn best practice that suits your business best, don’t copy and paste something from a megacorp. Sure, include elements from megacorp’s best practice if they are applicable, but don’t be a slave to the entirety of it.





  • LIVE BLACKBIRDS???

    Sing a song of sixpence a pocket full of rye,

    Four and twenty blackbirds baked in a pie.

    When the pie was opened the birds began to sing,

    Oh wasn’t that a dainty dish to set before the king?

    The king was in his counting house counting out his money,

    The queen was in the parlour eating bread and honey

    The maid was in the garden hanging out the clothes,

    When down came a blackbird and pecked off her nose!

    Moral of the story, don’t be a minor character in an 18th century nursery rhyme.



  • Yes, I shifted to my own domain after my default ISP of 20 years decided that email was just too hard, you know? They didn’t outright say it, they just started batch processing emails so that I’d get all my daily emails at around 2 am the next day. Super handy for time limited password reset emails!

    A few hours reading a guide and setting up a $5/mo linode email server with SPF and dmarc, a few more hours transferring 20 years of IMAP mail from my old account to a folder, and a month or so of changing a few site contact emails over each day when they emailed something to my old account, and now I’ve got an email server on my own domain that is 10 times faster at sending/receiving mail than my old ISP ever was.

    And now I can have [email protected] and [email protected] and random other disposable addresses so that when they are inevitably sold off for the $$$ I can just dump them and maintain a spam free inbox.


  • You’re thinking of a firewall. NAT is just the thing that makes a connection appear to come from…

    That connection only “appears to come from” if I explicitly put a rule in my NAT table directing it to my computer behind the router doing the NAT-ing.

    Otherwise all connections through NAT are started from internal->external network requests and the state table in NAT keeps track of which internal IP is talking to which external IP and directs traffic as necessary.

    So OP is correct, it does apply a measure of security. Port scanning someone behind NAT isn’t possible, you just end up port scanning their crappy NAT router provided by their ISP unless they have specifically opened up some ports and directed them to their internal IP address.

    Compare this to IPV6 where you get a slice of the public address space to place your devices in and they are all directly addressable. In that case your crappy ISP router also is a “proper” firewall. Strangely enough it usually is a “stateful” firewall with default deny-all rules that tracks network connections and looks and performs almost exactly like the NAT version, just without address translation.
