Squid unexpectedly stopped working with my home internet connection. I created a temporary user:
cd /etc/squid/
sudo htpasswd -B squid-password temp
sudo service squid reload
tried the following command
curl -v -x https://developernote.com:3129 --proxy-user temp:<password> -I https://api.ipify.org/
with another internet provider and it succeeded.
(more…)With the command below
mogrify -path . -strip -quality 50% *.jpg
I reduces the size of the following images

The code below demonstrates how to access underlying range iterator by transformed iterator:
struct A
{
int x;
};
struct B
{
A* a;
};
std::vector<B> v;
int main()
{
auto a_range = v | std::views::transform(std::mem_fn(&B::a));
auto i = std::ranges::find(a_range, 5, std::mem_fn(&A::x));
A* a = *i;
B& b = *(i.base());
}
ROWID is of alias of an integer primary key:
CREATE TABLE test1(id INTEGER, b TEXT, PRIMARY KEY(id))
INSERT INTO test1 (id, b) VALUES (5, 'five');
INSERT INTO test1 (id, b) VALUES (6, 'six');
INSERT INTO test1 (b) VALUES ('seven');
SELECT rowid, * FROM test1;
Added video codecs to pjsip.conf:
allow=h263p
allow=h263
allow=h264
allow=vp8
