Nice landing page to check various aspects of IP addresses: [WayBack] ipvoid.com:
We offer a vast range of IP address tools to discover details about IP addresses. IP smtp blacklist check, whois lookup, dns lookup, ping, and more!
I irregularly use them to check out blacklist issues (yes, sometimes 8.8.8.8, 8.8.4.4 and even 9.9.9.9 appear on blacklists).

Some interesting links on the “open with” database:
Simple solution to clean the list:
# Clean up LaunchServices to remove duplicates in the “Open With” menu. alias lscleanup="/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user && killall Finder"`
These were by products of what I was really searching for:
Some applications are greyed out, for instance when editing the “Open with…” for the .cap extension (which are pcap network captures that Wireshark can process).
After the steps below, sometimes the menu still does not update for all files of that extension.
This alias helped me to get that to work: alias restart-finder='killall -KILL Finder'.
Links that helped me finding out:
The trick is to toggle “Recommended Applications” into “All Applications”:
Then you can select “Wireshark.app”:
The same happens when you filter on a name (for instance because you know that Wireshark will work fine):
A final thing is that you have to check “Always Open With” so it ends up in the list.

most websites are now using https by default.
And that’s great, but it also means that if you’re relying on poorly-behaved wifi networks, it can be hard to get online. Secure browsers and websites using https make it impossible for those wifi networks to send you to a login or payment page. Basically, those networks can’t tap into your connection just like attackers can’t.
So to get your brain-dead hotel, airport or other WiFi connection to work:

This indeed was an Excel 2011 for Mac thing.
Even without macros or VBA modules, Excel 2011 for Mac shows this dialog when opening a .xls file.
The solution was simple: save as .xlsx.

Some interesting thoughts on DVCS: [WayBack] Unorthodocs: Abandon your DVCS and Return to Sanity – bitquabit
Besides the very good point it raises about DVCS (Git, Mercurial and most other DVCSes treat the whole state of the repository as the atom) it also indicates quite a few shortcomings:
I see many other advantages of DVCS systems (for instance that you only need to locally have the branches you are interested in, way better tooling for DVCS systems, ditto for sites hosting DVCS), but it always a good thing to know the weak spots of what you are working with.

Examples like the one below from [WayBack] Scopes and names can really be deceiving. A root class and a descendant class can both have public fields, properties and methods with the same name… – Lars Fosdal – Google+ used to be part of the “language day” during my 5 day Delphi introductory courses.
Maybe I should find back more of those from the days, brush them up a little, then post them in a repository.
The thread has some nice references to tools that give better warnings and comparisons with other languages.
Anyone wanting to assist with that?

Your Delphi “licensed to” might be totally different from what it is actually licensed to.
From [WayBack] Hello people, any idea what exactly mean …licensed to test ??? My Delphi is registered with a valid account, subscription, serial number and so on. – Dobrin Petkov – Google+, at least these sources might be used different from the actual licensee name:

One day, on a legacy Linux system, logrotate managed to skip some files in the middle of a sequence in /var/log.
Since I didn’t have time to sort out the cause (the system was being phased out), I used this to compress the rest of the log-files (dated in 2017):
sudo -u bash
pushd /var/log
ls | grep -vw xz | grep "\-20......$" | xargs -L 1 ls -alh
After that you can execute this in the same directory:
ls | grep -vw xz | grep "\-20......$" | xargs -L 1 time xz
It skips any xz files and includes only files in the year 2017.
I occasionally tracked progress with this:
ls -alh /var/log/ | grep -v xz | less
That got back a few gigabytes of disk space, just enough to help me migrate the system away.
