After the most recent windows update (I downloaded about an hour ago), I can no longer locate my Ipython Notebooks. I run the Ipython Notebook as administrator since these wouldn't print properly otherwise, and this would show and save notebooks from/on a different location from the default (the default location being the one wherein I don't have to run as administrator). With this most recent update, the ran-as-administrator notebooks no longer show up, and I also can't locate them in my hard drive. I tried a system restore but this didn't help. I'm using Python 2.7 with Windows 7 professional on a Thinkpad T520.
I want to know where I can find the missing notebooks. These don't know show up in the Ipython Notebook home page, and also when I search the system for .ipynb files.
I found the files. These were in the System32 folder.

I'm currently using Manjaro Linux 18.1.2 and want to change my desktop environment from KDE to Bspwm. I tried to find find some guides, but failed to. Only some examples for popular managers like XFCE or Gnome, but their examples didn't help. Maybe it's because Bspwn is not that popular.
So can anyone provide quick guide how to do it without reinstalling the whole system?
BSPWM is a window manager, not a desktop environment. What you probably want to know is how to change KDE's default window manager (kwin) to BSPWM.
see
Basically, install bspwm if you haven't already and create a new executable shell script wm.sh in yourhomefile/.config/plasma-workspace/env with the line
export KDEWM=/bin/bspwm
This is self explanatory but it's setting KDE's default window manager from kwin to bspwm. Restart your PC and you should have bspwm.
I have WampServer Version 3.1.4 64bit installed on Windows 7 and it comes with PHP versions php5.6.38, php7.0.32, php7.1.22, and php7.2.10. I would like to use php5.6.x rather than php7.x.
So, when I switch from php7.2.10 to php5.6.38 from the server tray icon; it does not update the actual php version which is shown by phpinfo().
On localhost, it still says:
PHP Version: 7.2.10
However, it is updated on CLI side. This is tested with running this in the cmd:
php -v
The result is :
c:\wamp64\bin\apache\apache2.4.35\bin>php -v
PHP 5.6.38 (cli) (built: Sep 13 2018 12:45:08)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
After restarting WAMP services, and re opening the terminal, and restarting computer, it still not updated through phpinfo. It probably related the php version used by Apache service. How can I change this to 5.6.x
Any suggestions ?
Many thanks
Note : The issue is not related with changing php cli version as it was pointed here. I do not understand why some of them insist that this is potential duplication without reading the post carefully.
I have faced kind of similar issue, I have installed wampserver upgrades from https://wampserver.aviatechno.net/?lang=en. I needed php 7.3 and 7.4, after installing the php upgrades, those new versions were not being reflected in wampserver traymenu (left click on wamp icon->php-versions). After spending quite some time looking into this, finally could fix this by following steps :
Clearing logs (right click on wampserver icon -> tools -> empty logs)
[my php log file was 300+ MB].
Restarted wampserver and it was good to go.
I found solution from this thread http://forum.wampserver.com/read.php?2,159184
(TL:DR) Use left click -(instead of right click)- menu to change PHP versions.
(Long explanation)
Hi, this happened to me today. I was trying to change the php version from 7.2 to 5.6 to test something. However, Wampserver was not changing the web version of php. After much searching in the web and noticing in certain videos that some people were getting a different menu than me in the wamp server icon, I realised that there is a whole left click menu in wampserver in which you can change the php version and it does change the web version of php.
I understand that this can be a bit confusing for people who are used to using wampserver, but for someone who is using it for the first time, we are not used to having a left click menu in the bottom right icons. I hope this saves some time for others who have a similar issue than mine.
The wampmanager->Tools->Change PHP CLI Version menu only changes the version of PHP that will be used by wampmanager.exe to run all the PHP scripts that provide all the functionality of WAMPServer.
It has no effect on the version of PHP that will will be run from the command line in Windows.
If when you open a command windows and run the PHP interpreter >php.exe you actually get to the PHP interpreter, then you must have added one of the possible paths to one of WAMPServers PHP folders to the Window's PATH. You should never do this with WAMPServer, so if this is what you did, UNDO IT! This is for obvious reasons as you could have multiple versions of PHP available and want to run any one of them at any time as the CLI Version to test some code against multiple versions of PHP.
Instead create yourself a little batch/cmd file that accepts a php version as a parameter like in this answer I posted a while ago
With that you can set the PATH temporarily for the life of a command window ONLY. You can also make it include a PATH to the PEAR and/or COMPOSER folders at the same time, if you use either of these.
To check All VC Runtimes
There is a tool for checking if you have all the possible required VC Runtimes installed. Go to this page, the backup repo for WAMPServer, and download the little utility called Checks VC++ packages installed you will find it down near the bottom of the page. Download and run it, then throw it away, as it changes over time as new VC Runtimes become required.
I'm experimenting with the new Windows Subsystem for Linux as a way to develop Rails applications in Windows. I have WSL installed and I have Ruby in it but how do I use that Ruby from a Windows GUI application, specifically, RubyMine:
This is so I can easily start rails, run tests, etc.
If anyone is wondering how this can be done at this time with the latest version of Ruby, there is a WSL connector for the remote repo of ruby.
[Update 2020-10-30]
Updating the response below as a lot has changed and improved since my initial reply in 2017 😜
The awesome team at JetBrains have enabled RubyMine to talk to WSL via SSH and to use the "remote" Ruby interpreter, and even debug Ruby code running in WSL! :)
Also, in Windows 10 1903, WSL provides the ability to access Linux distros' filesystems from Windows via the \\wsl$\ pseudo-UNC path.
In Windows 10 2004, WSL added a Linux icon to File Explorer making it easier to discover this pseudo-UNC path.
So, in Windows 10 >= 1903, Windows apps, editors, IDEs, etc. can also access files stored in, for example, \\wsl$\Ubuntu\...!
👉 Notes:
Accessing files in Linux via \\wsl$\... will be slower than accessing files locally because file IO requests have to be marshalled back and forth via a 9P fileserver. If you intend on accessing files intensively, we recommend storing the files in the filesystem closest to whatever you'll be using to access those files most intensively.
Thus ... while you can access files directly via the pseudo-path, using WSL integrations built-in to tools like RubyMine, VSCode, Visual Studio, etc. should be preferred if available.
I have Python 2.7 installed in "C:\Python27". Now I run 1st demo of Python4delphi with D7, which somehow uses my Py2.7 install folder. If I rename Python folder, demo can't run (without error message). I didn't change properties of a demo form.
What part/file does py4delphi use from my Python folder?
python4delphi is a loose wrapper around the Python API and as such relies on a functioning Python installation. Typically on Windows this comprises at least the following:
The main Python directory. On your system this is C:\Python27.
The Python DLL which is python27.dll and lives in your system directory.
Registry settings that indicate where your Python directory is installed.
When you rename the Python directory, the registry settings refer to a location that no longer exists. And so the failure you observe is entirely to be expected.
Perhaps you are trying to work out how to deploy your application in a self-contained way without requiring an external dependency on a Python installation. If so, then I suggest you look in to one of the portable Python distributions. You may need to adapt python4delphi a little to find the Python DLL which will be located under your application's directory. But that should be all that's needed. Take care of the licensing issues too if you do distribute Python with your application.
Hopefully this has not been asked/answered before, but I haven't found anything that fits my issue.
I installed mono on CentOS 6.2 as described here using an rpm and then downloaded FSharp-2.0.0.0. I got it all set up and fsi works great (as long as I pass it the option --gui-) while as root. However, when I try to do it as a plain user I get an error telling me something about not being able to access the registry.
Here is a screenshot:
I'm not sure what the issue is (I've never used CentOS before, but a lab I work in does and I want to put FSharp on it for data processing -- thus I have to use CentOS, which I've read can be troublesome with mono). Thanks for any help!
I know little about CentOS, but the error message seems fairly clear, the mono process running fsi.exe does not have access to a file (the file path is given in the message). So it should be just a matter of running as root to give yourself access to the file, or better yet granting the current user access to this file via chmod (or similar tool).
