Why is chown not working within Docker? It _used_ to..?
FROM ubuntu:22.04
RUN mkdir /tmp/blah && chown www-data /tmp/blah && ls -ld /tmp/blah
# When it's building I see
# drwxr-xr-x 2 www-data root 4096 Aug 17 04:12 /tmp/blah
# Why when I run this with docker container run user/image /bin/ls -ld /tmp/blah
# do I see
# drwxr-xr-x 2 root root 4096 Aug 17 04:12 /tmp/blah

Hi.
We're trying to implement this code at https://bitcoin.stackexchange.com/a/32308/235711 in python with the
ecdsa library. Unfortunately, we're not clear on what language this code below is written in.. C++? C#?

We'd like to verify using python, but it doesn't seem to work. Can someone tell us what we're doing wrong?

Last active February 6, 2022 07:52
I have a set of ranges, and a set of data with positions, and I'd like to create averages of a specific window size (I'm using 3 in this example) of every possible sub range within these left and right positions... (I can't actually think of a good way of describing it, so here's a demo I made to perhaps make it clearer.)
create or replace table data (
pos int not null,
val float not null,
constraint data_pk primary key (pos)
);
insert into data (pos, val) values
(1, 2), (2, 3), (3, 5), (4, 7), (5, 11), (6, 13), (7, 17), (8, 19),
(9, 23), (10, 29), (11, 31), (12, 37), (13, 41), (14, 43), (15, 47), (16, 53),
(17, 59), (18, 61), (19, 67), (20, 71), (21, 73), (22, 79), (23, 83), (24, 89),
