  • Only good if the laptop has a proper tablet mode for note-taking/drawing with a pen stored inside a chassis slot. I’ve a non-convertible Thinkpad that for whatever reason has a touchscreen and I end up activating it by accident more than on purpose. It also seems that the additional electric fields associated with the touch functionality makes the screen attract far more dust than any non-touch laptop.


  • Have used both and Philips felt much more satisfying. Check-ups at the dentist turned out fine either way though. Problem with Oral-B are the hollow brush stems with a hole in the middle. The gunk I find built up inside when it comes time to replace the head has me paranoid.

    The cheapest “One by Sonicare” model felt too weak IMO but also unless you need the fancy health tracking features, there’s not too much to be gained going beyond the 4100. Brush head replacement prices aren’t too bad online.

    If you do go for Oral-B, be wary of aftermarket brush heads since there are moving parts inside and the mechanism in the cheap ones will break within a month, so the brushes stop actually spinning.

    Either way, go with the rechargeable models. On the AA/AAA-powered ones, the drop in brushing power isn’t too noticeable day-to-day. But the moment you replace the batteries, you realize how much you’ve missed out while the motor was gradually starved of voltage.



  • Several times in my own electronics and many times in secondhand items. The potassium hydroxide electrolyte never quite evaporates and seeps under the crevices, requiring a full disassembly to prevent further corrosion.

    Worst offenders are the pesky little alkaline button cells. Every alkaline cell inevitably evolves hydrogen gas as the electrochemical reaction proceeds and in those tiny canisters, the gas very quickly has nowhere to go but out along with the cell’s guts. The secret is to get the silver oxide versions, same voltage, a bit pricier, but far less leakage.

    I guess the silver lining to the declining popularity of AA and AAA powered devices is that I can finally afford to use only Ni-MH or primary lithium cells in all of my devices. Those chemistries are mostly immune to leaking.





  • Tempered glass and thick case. Specifically one of those cases with interlocking front and back pieces. Makes it look and feel like it was always an integral part of the phone. In fact it is now, after I took out the glue to replace the battery and couldn’t be bothered to put glue back.

    Tore out the plastic sheet included with it and stuck a glass protector in its place. Glass doesn’t have to be expensive, I got mine in a 2-pack for just $6. Maybe the more expensive ones have some oleophobic, anti-glare, or anti-scratch, but mine’s held up nicely for over 3 years.

    I don’t mind the extra heft at all and would probably have perpetual anxiety if I had to use a phone without a case.




  • You could make it about equivalent to the protections afforded by the typical BIOS password, i.e. the attacker must first disassemble your laptop to reflash the spi chip or pull the hard drive. A grub.cfg like so would do, assuming everything in encrypted partitions:

    set prefix=(memdisk)/boot/grub
    set superusers="myuser"
    password_pbkdf2 myuser grub.pbkdf2.sha512.10000.<your hashed password>
    cryptomount -u <UUID of LUKS container>
    search.fs_uuid <UUID of the root filesystem under LUKS container> root cryptouuid/<UUID of LUKS container>
    configfile ($root)/@rootfs/boot/grub/grub.cfg
    

    Assuming you boot directly to GRUB or locked out the SeaBIOS boot device selector, then GRUB will only ever look for a boot device matching your disk’s UUID; attempting to do anything else aside from entering the LUKS passphrase will prompt for the GRUB password. You’d still have your own recovery path by pressing Esc, entering your GRUB password, and dropping to the GRUB shell. Bonus points for patching the GRUB code so it doesn’t echo the UUID of your disk.

    No, it isn’t bulletproof against physical access. But yes, I had the same question you did when starting out with coreboot and this was the solution I came up with.


  • What I like to call temporal horror vacui. Some things are easy to start, they do require some periodic checking, but are otherwise passive. So I’ll start a 3d print, get water boiling on the stove, or start running an offline backup. Then my mind is bothered that those are such “empty”, “unproductive” tasks, and so reactively fills in the gaps with things I’ve been procrastinating like dishes, meal prep, planning, etc.

    Also body doubling. For emails, I have a good friend at work who also massively struggles with them, so every now and then, we make a commitment to each other and for an hour or two, both sweep through our inboxes, with a bit of commiseration along the way.

    Anyway, it’s still a struggle that makes me wonder about seeking an ADHD evaluation … next month maybe.



  • I use it to generate little bash and python scripts for mundane tasks, random ideas I don’t have a good starting point for, or boilerplate code I don’t have the energy to write manually. Or also to decipher cryptic error messages and logs. Nothing that I publish though, just all testing and personal scripts.

    I do this with models running locally on my gpu. 14B parameters is surprisingly decent and fast enough for a 16 GB slot-powered workstation model.

    For fun, since the model is local, I also toss in some excerpts of my writing, see what it can glean from my style and vocabulary, something I’d never do with an LLM hosted by someone else for obvious reasons.



  • Focus follows mouse and unchecking the option to auto raise the active window. Couldn’t live without it and being used to it has made me extremely clumsy when I do pick up my Windows work laptop.

    I change the taskbar clock to be a one-line MM/DD HH:MM:SS format, drop in my customized locale (based on en-US for maximum compatibility, but without having to deal with US formats and units that I’m not fond of), and point the taskbar shortcut for my text editor to a script that creates a pre-named file and launches the editor with autosave enabled. Because having to manually save and come up with a name for your spur-of-the-moment notes sucks, automatically generating 20260831_text_1 is so much better than a, b, a2, etc.

    XFCE specific, I get rid of the second panel full of launchers. Acquired taste, but also Chicago95 theme and icon pack.







  • For anonymity alone, no. You ought to at least aspire to live the nomad lifestyle first and put up with its challenges, then enjoy whatever anonymity comes from it as a bonus.

    If you don’t mind apartment living, you could consider the arrangement I had at one point. Private landlord who didn’t run background checks, accepted payment in any reasonable form, many tenants, communal mailbox without apartment numbers or names required. Internet, utilities, etc. all rolled into rent and not individually metered. Might be harder to find but they exist.
