  • It will die when there is an alternative app that competes with marketplace. That + messenger keep most people there. Signal (or whatsapp which while meta, isn’t tied to fb account)'already can replace messenger.

    That is simply the truth. Here is Belgium we have an app called 2dehands which is very prolific and have a way better interface and experience than marketplace (even though it is nowhere near perfect or great).

    Marketplace is definitely completely secondary to 2dehands in the Flemish part. Brussels still uses marketplace a lot, but literally all marketplace needs in order to slowly die off is competition but the 2nd hand market is not a lucrative app space with no real funding opportunities outside of data sale so nobody does it.


  • Interesting thoughts in this thread.

    I simply switched to having an unencrypted boot partition with the automount key on a flash drive. After it boots the server, just remove the whole boot partition. Physical separation is much much more powerful for smash and grabs, petty seizures, and evil maid than TPMs.

    The flash drive is stored securely when I am in the area. Flash drive can go in the machine if I am away for a while or have something critical.

    I go a step further and have password-only data drive description so I have to ssh in to set up the data drives again, but the principle would be the same.


  • Most of what you see on charcoal filters are literally just dust and water.

    Plus, nobody actually keeps up with filter maintenance. Charcoal filters sitting in free air are horrible for this. Charcoal filters have a saturation time as a function of mass

    I was looking into fiber laser safety for ABS vaporization for my company and came across a few studies (can’t find right now).

    Activated charcoal filters in free air become saturated after like a week or so of use just because of the fact that they absorb both the tiny amount of unwanted compounds along with massive amounts of common air particles. You really need an enclosed container with butterfly valves like the Weller units https://www.weller-tools.com/us/en/filtration/products/solder-fumes with heavy carbon filters along with other absorbers in order to not completely saturate.

    After the first week, the “solder fume extractor” filters are literally just collecting dust. Your charcoal filter looks exactly like my mesh computer dust filter in the picture as far as what it caught.




  • Lol docker is literally the easiest and most user-friendly server program administration method… It is literally one user-readable configuration file and everything is automatic.

    Vm’s are more complicated and have you even tried managing many services on bare metal with conflicting libraries, database versions, etc…? That is truly arcane arts of programming scripts.


  • Interesting. I had no idea about this project!

    Sadly they are using the Maxim sensor hub with seperate LEDs and data acquisition where i am just using an all-in-one sensor.

    Who knows? I am making the development board right now so maybe I will find that using the same part will make it easier lol

    Very cool project! I wonder when it is called the “pi” when there is nothing related to Pi or the raspberry/orange/banana pi ecosystem? 😂


  • My hobby right now is making a completely local fitness watch without any screen or distractions. Just logs heart rate, spo2, activity, and sleep using actual Bluetooth standard profiles (HRP, POP, PAMP, etc… Instead of proprietary hacked together custom profiles of most watches). No GPS either because if I want that, I will just bring my phone. Maybe an extension of my job though since I design medical device electronics for work. The only feedback is an LED and good LRA haptics (hopefully). I hope to make it compatible either with whoop replacement straps or standard watch bands.

    Bit of a serial hobbyist:

    • gardening
    • cooking and making new recipes
    • weight lifting
    • running (need to get back into it)
    • implementing a smart home
    • growing mushrooms
    • baking bread
    • making cheese (stopped because Belgium has almost no non-ultrapasteurized milk anymore)
    • designing flight sticks for space simulators
    • running a home server






  • KNX is indeed a protocol, but there is a whole multi - manufacturer ecosystem around it. It is mostly used in the commercial space. It is literally the ultimate smart electricity ecosystem for reliability.

    Everything that I did is done in the electrical box so you buy traditional push button switches for the walls with very thin, cheap cable, and then your lights as normal.

    It is wired originally with twisted pair bus that delivers power and data. They branched out also into wireless products also now using 898MHz bands (same as zwave).

    The protocol is very tightly regulated but everything is guaranteed to work. It isn’t wireless so it doesn’t have shitty mesh problems like zwave and ZigBee have with many devices. You don’t get bad device behaviors and disconnects with power outages. There are no shitty batteries to replace (and no fibaro zwave devices having ridiculous battery drains when outside of a +/-10C range from 20C).

    It will simply work and keep working for your lifetime, unlike many or most ZigBee and Zwave devices.

    Unlike Starfighter says, It actually isn’t that expensive for basic home users. if you do it correctly and don’t go for “everything being LCD panels”. It is much much cheaper than retrofitting every socket with ZigBee or zwave smart switches. I am fully stripping and renovating my house and it is literally about the same price as doing everything with modern teleruptors, with 10x the functionality. If you include the license, then maybe 10% more expensive.

    It cost me literally 1400€ 32 switches, 16 circuits of on/off lights and fans (or I could use them for roll blinds), and 4 dimming circuits, plus temperature and humidity sensors to smartly turn on bathroom fans. It is €30 for every Shelly wave module which would be 1000€ just for the switches alone with no dimming or sensing. Plus if you are already rewiring you house, you get to save a shit ton of money using small gauge cable with potential-less contacts.

    Don’t get me wrong, zwave is great, but KNX is absolutely king at only a marginal price premium (for standard home users, commercial focused HVAC controllers and such are expensive as hell)

    Edit: also one thing to note is that all UI elements of KNX through pretty much all the manufacturers look like they are from 2010 or earlier (and they often are). I much prefer other options or a Home Assistant tablet or something.



  • I really miss Microsoft AD configuration GUI.

    Wait, no, that sort of group you have to make through Entra, formerly Azure admin center, wait no they actually wanted a SharePoint site for the group, wait no you can’t do that through entra even though you can see the groups, you have to do that through O365 admin center, wait no you can only make a SharePoint aaand teams group there, you have to click more -> SharePoint admin center and then create a new group there, but not the default, you have to click “show more group types”, but where can you modify the members of this group? Oh you can just go back to O365 admin center to do that. Now you want to make some small access changes to the force-created email for the group? Oh well you have to go to Exchange admin center for that. Wait, not Outlook admin center? No they are named different things just to make it easy.

    Now someone who made an event involving the group is on holiday so I have to remove it, I can do that from exchange admin center right? Well actually the easiest way to do that is to log into Exchange from a power shell terminal through the GUI pop-up and terminal commands. But wait, the search for the event actually doesn’t work there ever, even with the exact name? I guess I will give myself rights to the calendar, reboot Outlook, go to the calendar, remove the event, go back to the terminal, remove my rights to the calendar, restart outlook.

    Actually, I don’t miss Microsoft sysadmin tools.
