  • Pretty tiny. It’s Slovakia. 49,035km2
    But if you travel daily, you’ll still do quite some distance.

    Just tried checking the Amtrak website, but I am not sure what I am looking at. Is it different train classes? Does the price differ by time?
    I just checked something that seems like a more or less normal route. New York City to Philadelphia, 1 hour 27 minutes, can’t find the distance, at 7:17am. “Coach” option says $92.

    Oh, hell, you even have to give them your ID? Why? I chose Adult ticket.

    Oh well, looks more or less like a straight line on map. Let me get the distance from map, let’s say 82mi approximately. Closest for comparison is Považská Bystrica to Bratislava at 6:54am, 169km (105mi), but I really just wanted to avoid something shorter. That’s 1 hour 39 minutes, so close enough by time at least. 2nd class is €8.30.

    So if I checked right, for more or less the same thing that’s $92 vs €8.30. Wild.






  • the so-called Chromebook Challenge includes students sticking things into Chromebook ports to short-circuit the system.

    I am rather surprised that works. I thought any modern device would have overload protection in place. I think I even remember accidentally tripping it on some device, but it would just reset after reboot.
    I also tried to see the max output current of my previous phone this way. Load it up till the protection trips. Result: Stable up to 2.1A, tripped at 2.5A.

    Oh, yeah. A Xiaomi phone charger I have also shuts down if I either overload it or immediately load it near max rating rather than gradually increase the load.




  • Time to calculate how much 1 marshmallow is worth in time considering minimum wage in my country.

    Let’s begin.
    Minimum wage in Slovakia is €4.69/h.
    An 80g bag of Jojo marshmallows is €1.19 at Tesco.
    It claims one portion is 3 marshmallows which is 11.7g.
    Therefore 1 marshmallow is 3.9g.
    Therefore there are 20 - 21 marshmallows in the bag.
    Therefore 1 marshmallow costs roughly €0.058.
    €4.69/h is €0.078/m or €0.0013/s.
    Therefore, 1 marshmallow costs roughly 44.62 seconds of work time.

    Well, assuming there are no taxes. So maybe something close to 1 minute per marshmallow. Although… maybe if we add total time, including time you’re not working… 12 marshmallows an hour, 288 a day, 2016 a week, 8640 a month. That’s €501.12/month.

    Based on this the minimum monthly wage after taxes and all is €661.80/month.

    Conclusion: It is worth the 5 minutes.



  • Now if you want to get really convincing and prank the city big time, get a team of people, steal the necessary equipment and materials. Remove the spikes carefully, making sure the surface is nice and smooth. Add benches, trash cans and large planters with some nice plants. The choice is yours. Make a large sign with name of the city on it, and add it to the space so that it’s visible.
    Next, a big thing.
    Close down the road on both sides. On one side, remove the road lines, paint a bicycle lane and add street lights. Add more benches and trash cans along the way.
    On the other side, from which that sign with city name is clearly visible, you’ll rip out the road. Then fill the hole with chunky rocks. Lay evenly spaced sleepers on top of them, put steel rails on top, and anchor them to the sleepers. Next, you fill the gaps with some smaller stones along the way.

    Optimally, you’ll keep this prank ongoing through the entire country and add other necessary components to it.




  • I quite like my ancient inkjet HP. Keeps printing with “empty” cartridge just fine, and the bottle of ink from AliExpress lasts a long time even if drenching paper with dark mode documents.
    I paid 71 cents on sale for 500ml of ink, though it’s otherwise around 20 bucks. Still worth it.

    Now, there may just be one problem for most, it doesn’t work with Windows anymore. HP website doesn’t provide drivers saying they get automatically installed by Windows. Windows says it can’t find drivers and to use manufacturer’s website.

    But it works with HPLIP on Linux.

    Oh, and 1 more thing. There’s a high DPI mode that can almost match laser in sharpness. But, it takes 20 minutes per page. Yes, not a typo.
