About a year ago, [WayBack] Rumors of Cmd’s death have been greatly exaggerated – Windows Command Line Tools For Developers got published as a response to confusing posts like these:
But I still think it’s a wise idea to switch away from the Cmd and to PowerShell as with PowerShell you get way more consistent language features, far better documentation, truckloads of new features (of which I like the object pipeline and .NET interoperability most) and far fewer quirks.
It’s time as well, as by now, Windows 7 has been EOL for a while, and Windows 8.x is in extended support: [WayBack] Windows lifecycle fact sheet – Windows Help:
Client operating systems Latest update or service pack End of mainstream support End of extended support Windows XP Service Pack 3 April 14, 2009 April 8, 2014 Windows Vista Service Pack 2 April 10, 2012 April 11, 2017 Windows 7* Service Pack 1 January 13, 2015 January 14, 2020 Windows 8 Windows 8.1 January 9, 2018 January 10, 2023 Windows 10, released in July 2015** N/A October 13, 2020 October 14, 2025
Which means the PowerShell version baseline on supported Windows versions is at least 4.0: [Archive.is] windows 10 powershell version – Google Search and [WayBack] PowerShell versions and their Windows version – 4sysops
PowerShell and Windows versions ^
PowerShell Version Release Date Default Windows Versions PowerShell 2.0 October 2009 Windows 7 Windows Server 2008 R2 (**) PowerShell 3.0 September 2012 Windows 8 Windows Server 2012 PowerShell 4.0 October 2013 Windows 8.1 Windows Server 2012 R2 PowerShell 5.0 April 2014 (***) Windows 10
So try PowerShell now. You won’t regret it.

Quite a while back, I got attended to Ben, blogging: Show the complete apache config file:
If you really want to see all the complete config settings, there is no existing tool for that. This Stack Overflow page answered this question pretty well: You can use apachectl -S to see the settings of Virtual Host, or apachectl -M to see the loaded modules, but to see all settings, there is no such tool, you will have to go through all the files , starting from familiar yourself with the general structure of the httpd config files.… script …The usage is simple: Run it as
python CombineApacheConfig.py. Since there is no additional parameters given, it will retrieve the default Ubuntu apache config file from/etc/apache2/apache2.confand generate the result complete config file in/tmp/apache2.combined.conf. If your config file is in different location, then give the input file and output file location.Note: Apache server-info page http://127.0.0.1/server-info also provide similar information, but not in the config file format. It is in human readable format. The page works only when it is open from the same computer.
python CombineApacheConfig.py /etc/apache2/httpd.conf /tmp/apache2.combined.conf

Just in case you are wondering what these
%TEMP%\_MEI*folders are about: Google Drive apparently doesn’t clean up correctly when it exits because you log off or shut down Windows.This is ridiculous. It’s not as if there weren’t any options to let Windows do that cleanup if the program fails.
It is still not fixed:

Still doing it all these years later – only the size of the garbage left behind has changed (Size: 58.4 MB (61,303,879 bytes) Size on disk: 67.7 MB (71,061,504 bytes) 1/3 of which is icons) – why this isn’t committed to Chrome instead of held open in %TEMP% is beyond reasoning +Google Drive
Original forum source: [Archive.is] _MEI folder created at windows start – Google Product Forums
by Martin Friedl 3/17/13
Hi,
I just found out that on windows the google drive tool creates a ‘_MEIxxxxx’ folder on every startup of windows. The xxxxx is a number that differs at every startup. On my PC (with windows 7) this folder is created on ‘C:\’ and has a size of about 35MB. SO with every start of windows google drive occopies 35 additional MB. It looks as the content of the folder is mainly Pyhton-files.Is there a way to prevent google drive from creating an additional folder with every start of windows?
Best regards
Martin…

Klint said:
If you exit Google Drive by right-clicking the Google Drive icon in your Windows 7 notification area, and selecting Exit, then Google Drive shuts down properly and correctly deletes the _MEIxxx folder. Unfortunately, it leaves the folder behind if you leave Google Drive running when you log out or shut down. So, yes, it is a bug in Google Drive. It ought to terminate properly when the user logs out.

With system account starting with underscore:
dscl . list /Users
Without underscore, so only regular accounts:
dscl . list /Users | grep -v ^_.*

Wow: [WayBack] Wolfgang Rupprecht – Google+:
Dennis H. Klatt 1938 – 1988
I knew him at MIT. He was my undergraduate thesis advisor and was a kind and gentle person. When I knew him around 1980 he was about to build the prototype for the first Klatt Talker as it was called then. He had speech samples generated by running his mathematical model of the vocal tract on a large mainframe, but no way to generate speech in real time. I remember being quite happy years later when I heard he had convinced DEC to produce it. The local Boston radio stations would sometimes use it on air when they were goofing around. The initial voice (and the only voice early on) had a bug that made it sound like a Mexican accent to most people. It wasn’t intentional and was a bit of a surprise that a vocal tract modeled from first principles would sound that way. Going with that observation and figuring it was best to advertise bugs as features, the voice was often called “Carlos”. I didn’t realize that Hawking’s voice was also based on the Klatt models (and Klatt’s own voice at that!)
Poking around Google to see what else Google had on him dredged up one more interesting tidbit. There was a character in a TV cartoon called Deeklatt that used his voice. I wonder how many people realize that Deeklatt was a play on D. Klatt. Dennis, we should all be so lucky as to leave a legacy like yours.

I’ve a ton of slides, negatives and photos to scan and want to automate the process as much as possible. Think thousands.
Opinions are welcome on both the hardware to use and the process.
It looks like for slides and negatives the opinions vary between building your own rig, fiddling with flatbed lighting or buying a tad more expensive one.
But that was 3 years ago. How’s the state of the art right now?

I thought I had forgot about the SuSEfirewall2 changes (On my research list: migrate from OpenSuSE SuSEfirewall2 to firewalld) so assumed that was the reason I broke one of my secondaries (which runs on a Raspberry Pi 2):
Mistakes like these are the reason to have secondaries in the first place https://infrastatus.wiert.me and do port-mortems.
Which is kind of odd, as the SuSEfirewall2 didn’t throw any warnings like at this similar one:
This one still works because it is on the firewall in front of the Raspberry Pi 2:
(Screenshots of the above URLs are below).
In fact it was another mistake: I had forgotten to make the DHCP lease static, which resulted in a wrong IP address to be assigned upon reboot, instantly making the firewall rules invalid:
I could have fixed this remotely when I had thought about this.
