When connecting to berry over ssl fails from firefox, check the VPN.

Check cloudflare.

sudo over tramp


/ssh:berry|sudo:berry:/etc:

Resize image


convert -resize 20% 1677228853090.jpg decider.jpg

Convert file to utf-8


iconv -f iso-8859-1 -t utf-8 ea.iso -o ea.html

Update htdig index

Comment the 3 Rewrite lines in the http configuration (prevent redirection to https)


tar zxf /tmp/new.tgz
sudo perl -pi -e 's/Rewrite/# Rewrite/' /etc/apache2/sites-available/000-default.conf
sudo apachectl graceful
export DBDIR=/opt/www/htdig/db COMMONDIR=/opt/www/htdig/common BINDIR=/opt/www/htdig/bin
sudo $BINDIR/htdig
sudo perl -pi -e 's/# Rewrite/Rewrite/' /etc/apache2/sites-available/000-default.conf
sudo apachectl graceful
LC_COLLATE=C sudo $BINDIR/htmerge

Update git forks

This is especially valid for ~/git/mgirod/gcc (very active) but also for ~/git/mgirod/icu.


gcc> git pull upstream master
gcc> git commit -m 'pull update' -a
gcc> git push

Build debuggable

So far failed to understand how to avoid optimizations completely.


fstr> make CXXFLAGS="-std=c++11 -ggdb -Og" # was not working—maybe better now (6.3)
fstr> make CXXFLAGS="-std=c++11 -g -O0"

Debug


fstr> gdb fstr
(gdb) b 631
(gdb) run
(gdb) s

Useful:


(gdb) finish
(gdb) info stack
(gdb) q

Interesting files:

/usr/include/c++/6.3/bits/ios_base.h
/usr/include/c++/6.3/ostream
/usr/include/c++/6.3/fstream
/usr/include/c++/6.3/streambuf
/usr/include/c++/6.3/bits/char_traits.h
/usr/include/c++/6.3/bits/basic_ios.tcc
/usr/include/c++/6.3/bits/fstream.tcc
/usr/include/c++/6.3/bits/locale_classes.tcc

gcc-6_3_0-release:

~/git/mgirod/gcc-6.3/libstdc++-v3/src/c++98/ios_locale.cc
~/git/mgirod/gcc-6.3/libstdc++-v3/src/c++98/locale.cc
~/git/mgirod/gcc-6.3/libstdc++-v3/src/c++98/codecvt.cc

Expected effect: the string should get appended to the file


fstr> cat utest.txt; echo
