# Threshold Signatures
FROST is an algorithm that produces a regular schnorr signature, and allows a quite large number of unequal shares.
A threshold signature has the interesting feature that it is a randomness
beacon. If there is one honest participant party to the signing it generates a
random value unpredictable to all participants, This has obvious utility in

[FROST with unequal shares]:https://github.com/Trust-Machines/frost
Source code for [FROST with unequal shares] is available on github, implemented for the bitcoin elliptic curve.
Each of the participants acts as the trusted dealer for his own share, hands
out shares in it to everyone else, and the final key is the sum of everyone's
share.

hundred and fifty six dimensions. So a dimensionally reduced point is not
necessarily reduced by a whole lot.
Two hundred and fifty six dimensions is still an impractically large
dimensionality, albeit an improvement on what was likely a near infinite
number of dimensions.
To reduce it to something actually useful, need principal component
analysis. If non linear methods required, as likely they will be, neural
network methods.
For spaces of dimension higher than fifteen or so, clever methods of
nearest neighbour search generally fail, and people generally wind up with
brute force search, comparing each point to each of the others, and then

Thus all changes should be made, explained, and approved by persons

It is preferable to simplify the history recorded in git by rebasing the
changes in the branch that you want pulled to the most recent version
signed by the puller of the branch that you want it pulled into. This
produces an artificially linear history, which is likely to be more
intelligible and informative than the actual history. In particular, more
intelligible to the person who has been requested to pull.

If you amend file system UUID's referenced in fstab and boot, have to amend `/etc/fstab` and `/boot/efi/EFI/debian/grub.cfg`, then rerun `update-grub`.
But a better solution is to change all the UUIDs, since every piece of software expects them to be unique, and edit `/etc/fstab` accordingly. Which will probably stop grub from booting your system, because in grub.cfg it is searching for the /boot or / by UUID.
However, sometimes one can add one additional virtual disk to a sata

To couple to the desktop requires a pile of information and configuration,
which most people ignore most of the time. To the extent that they provide it,
they seem to write it for the Gnome based desktops, Cinnamon and Mate more
for Mate because it is older and has changed less.
An install program should use `desktop-file-install` which is presumably
customized for each desktop,
The autostart directory `$XDG_CONFIG_HOME /autostart' is a part of the
freedesktop.org/XDG [Desktop Application Autostart Specification].
`$XDG_CONFIG_HOME` is seldom set, in which case it is equal to `~/.config`, hence the autostart directory is nearly always `~/.config/autostart`
The desktop specification is chock full of references to `$XDG_foo_bar`,
which is confusing because these are environment variables that no one
ever sets, and which should never be set, which means that their default
values *almost* always apply. Further, many of the directories are not
default created, so the first program to write a file into them has to create them. Which is likely to be your program, because superuser is likely to
create a user specially for your program.
