  • Upon further reflection, spring stiffness does not care about length.

    It does. If you have two springs with the same diameter made from the same wire, but one spring has the double amount of coils, i.e. the double length, the longer spring will have half the stiffness (or the double compliance) of the shorter spring.

    This design would reduce the effective spring stiffness by half (and therefore the force)

    In fact it’s the opposite. The “dead” coils at the end and in the centre increase the overall (compressive) striffness of the spring.

    The most obvious other way to reduce stiffness would be reducing wire thickness, which could reduce reliability.

    Slightly increasing (or decreasing) spring stiffness by changing the wire diameter is much harder to do, as the diameter of the wire enters the stiffness factor by the power of four orders of magnitude, i.e. increasing the diameter from 0.4 mm to 0.5 mm increases the stiffness by factor 2.44. Thus, it’s much simpler to introduce ‘dead’ or fewer coils in the spring to increase its stiffness when the outer geometric design properties (spring diameter and length) are given by the design of the pen.





  • However, Valeskog told the newspaper [Dagens Nyheter] that it would refuse such a move which was “the opposite of what we stand for,” as he called for the U.S. to withdraw the demand.

    This is the polite Swedish way of saying “Fuck off!”

    He said it the U.S. embassy that benefits from the City of Stockholm, not the other way around. If the U.S. ended ties with the city’s planning office, the embassy would have difficulty getting a permit for construction. “It’s their headache, not ours,” Valeskog, added according to a translation.

  • If I was to install one more home partition from the LMDE installation USB, would it automatically fix things for me in Grub or would I have to fix things myself before or after?

    If I understand you right, you want to install two additional SSDs, one for Linux root (system), probably ext4 formatted, and one ‘home’ for your personal data?

    If that’s the case, the boot loader GRUB is going to be installed onto the system SSD and will usually automatically detect the Windows boot loader on your current, Windows only, hard drive. If it didn’t, you need to toggle an option in GRUB’s configuration file and run update-grub again.

    For your home-partiotion on the other SSD, there exist two options:

    1. The home partition is Linux exclusive, probably ext4 formatted (this doesn’t work with NTFS), and all your data will be stored there. Yet, afaIk, you need to install an ext4 driver in Windows to access the data when you’re on Windows.

    2. The home partition is mutually accessible. (This the setup on my wifes laptop). There it’s NTFS formatted and the respective folders (Documents, Downloads, Pictures,… ) are mounted one by one using bind in /etc/fstab to their Linux counterpart.

    Edit: I’ve forgot to mention that, first I created folders named Documents, Downloads,… on the new partition before being able to mount them in Linux.

    After copying the data in Windows from the old folders to the new ones, the old folders can be deleted and replaced by hardlinks to their new counterparts using the Windows command line or PowerShell.
