Reminder to self: adopt the below code to do $(…) expansion like the Delphi IDE does

Posted by jpluimers on 2018/07/26

The below code expands %…% for environment variables and $(…) for CSIDL values.

Someday I will find time to convert it to something that does expansion like the $(…) one from the Delphi IDE.

  • CSIDLsUnit

Switching from net-tools to iproute2 or not? You probably have no choice, but the iproute2 cheat-sheet is 20+ pages…

Posted by jpluimers on 2018/03/20

Last year I came across this semi-humorous post: [WayBack] Bwahahaha, now that they took your init and replaced it with systemd, they are coming after your ifconfig. Next thing is that they will come after your… – Kristian Köhntopp – Google+

Underneath is a bigger problem: net-tools had been dormant for a long time, which means a lot of people rely on the predictable behaviour – especially by parsing the output for post processing.

Those days are definitely over: net-tools is in more active maintenance now breaking scripts like crazing. So since the foundation of networking on most distributions is now iproute2, it’s better to learn iproute2.

That’s not easy though, so here is some background reading to do:

I got this little translation table from the last link:

program obsoleted by
arp ip neigh
ifconfig ip addr
ipmaddr ip maddr
iptunnel ip tunnel
route ip route
nameif ifrename
mii-tool ethtool

Getting close to 7zip GUI “Ultra” compression from a batch file

Posted by jpluimers on 2018/02/23

These are the command-line parameters I assembled to get close to “Ultra” compression from the 7-zip command-line:

"C:\Program Files\7-Zip\7z.exe" a -t7z -m0=lzma2:d1024m -mx=9 -aoa -mfb=64 -md=32m -ms=on -sdel filename archive.7z

This will move filename to archive.7z using maximum compression.

Sometimes this is slightly better than “Ultra” compression from the 7-zip UI, sometimes slightly worse, but never far apart.
