Stop Microsoft Edge warning you before quitting on macOS

My new client only supports Microsoft Edge for logging onto their systems. Thus, I needed to install that onto my iMac and Mac Mini devices for those occasions when I am not using a Windows device (as it happens, I have yet to try that with Linux). However, Edge issues a warning on exiting it using the CMD+Q shortcut, the quickest way to do that and safer than clicking on the red X on the top right of the application as I have found with other situations on macOS (incidentally, that is similar to using the CMD+W keyboard shortcut). To get rid of the warning, I needed to go to Settings > Appearance > Browser behaviour and features > Warn before quitting with ⌘Q. Once there, it was a matter of toggling the setting to the off position and I was done. However, placing that under Appearance remains an odd decision to me.

What to do when Tuta Mail issues this message when logging into an account on macOS: Could not access Secret Storage

Two things changed before Tuta Mail stopped working as before: modifying Keychain Access settings and upgrading macOS from Sonoma to Sequoia. Either could have been a cause or none of them. The first of these was more likely a culprit than the other.

The result was the same: logging into Tuta Mail yielded an error like this: Could not access Secret Storage. The solution essentially is a two-step process: remove the app and delete its settings folder. Reinstallation then happens after these.

In Finder, go to Applications and move Tuta Mail to the Bin before clearing it from there. That uninstalls the app.

The next step needs you show hidden files and folders using the Command + Shift + . shortcut. Then, go to your home folder (this may need use of the Command + Shift + H shortcut). Open up the Library folder and find the folder called Application Support. Enter that and find the subfolder named tutanota-desktop. That needs to go to the Bin too before expunging it from there. Doing that provides the clean slate for restoration to commence.  After this, using the Command + Shift + . shortcut again hides the normally hidden files and folders once more.

Nothing is resolved with the removal of /Users/[username]/Library/Application Support/tutanota-desktop. Using the rm command from the command line interface will remove it faster than Finder, though that may be easier for many users.

Getting rsync to resolve symbolic links

Given how Dropbox changed its handling of symbolic links in 2019 such that internal links within a Dropbox file hierarchy got fixed and links leading outside from the Dropbox area no longer worked. Thankfully, the rsync utility found in many Linux and UNIX settings does not do that, as long as you have called it correctly.

By default, symbolic links are synchronised like any other file. That is what Dropbox does now. To get rsync to resolve the links as shortcuts to either a single file or more likely a folder containing more than one file, it needs the -L switch or option in the command. When that is present, the linked file or files will get synchronised and honours the point of having these links in the first place: allowing more flexibility with folder structures and avoiding any duplication of files and folders.

Opening up Kindle for PC in a maximised window on Windows 11

One irritation with the Windows app for Amazon Kindle is that it does not open in a maximised window, and it scarcely remembers your size settings from session to session. Finding a solution to this sizing issue is no easy task, so I happened on one of my own that I previously used with File Explorer folder shortcuts.

The first step is to find the actual location of the Start Menu shortcut. Trying C:\Users\[User Name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Amazon\Amazon Kindle should do that.

Next, right-click on the Kindle icon and choose Properties from the context menu that appears. In the dialogue box that causes to appear on the screen, look for the "Run:" setting. By default, this appears as "Normal Window" but you can change this to "Maximised", which is what I did before clicking on Apply before doing the same for the OK button to dismiss the dialogue box.

If you have pinned the shortcut to the taskbar or elsewhere, you may need to unpin it and pin it again to carry over the change. After that, I found that the Kindle app opened up in a maximised window as I wanted.

Creating soft and hard symbolic links using the Windows command line

In the world of UNIX and Linux, symbolic links are shortcuts, but they do not work like normal Windows shortcuts because you do not jump from one location to another with the file manager's address bar changing what it shows. Instead, it is as if you see the contents of the directory at another quicker to access location in the file system, and the same sort of thinking applies to files too. In some ways, it is like giving files and directories alternative aliases. There are soft links that point to the name of a given directory or file, and hard links that point to actual files or directories.

For a long time, I was under the mistaken impression that such things did not exist on Windows until I came across the mklink command, which came with the launch of Windows Vista at the start of 2007. While this feature might not be widely known, it demonstrates that Windows did adopt some UNIX and Linux capability long before other UNIX-like features, such as virtual desktops, were introduced in Windows 10.

By default, the aforementioned command sets up symbolic links to files and the /D switch allows the same to be done for directories too. The /H switch makes a hard link instead of a soft link, so we get much of the functionality of the ln command in UNIX and Linux. Here is an example that creates a soft symbolic link for a directory:

mklink /D shortcut target_directory

Above, shortcut is the name of the symbolic link file and target_directory is the destination to which it links. In my experience, it works best for destinations beyond your home folder and, from what I have read, hard links may not be possible across different disks either.

Smoother use of more than one SAS DMS session at a time

Unless you have access to SAS Enterprise Guide, being able to work on one project at a time can be a little inconvenient. It is possible to open up more than one Display Manager System (DMS, the traditional SAS programming interface) session at a time only to get a pop-up window for SAS documentation for the second and subsequent sessions. You don't get your settings shared across them, either, while also losing any changes to session options after shutdown.

The cause of both of the above is the locking of the SASUSER directory files by the first SAS session. However, it is possible to set up a number of directories and set the -sasuser option to point at different ones for different sessions.

On Windows, the command in the SAS shortcut becomes:

C:\Program Files\SAS\SAS 9.1\sas.exe -sasuser "c:\sasuser\session 1\"

On UNIX or Linux, it would look similar to this:

sas -sasuser "~/sasuser/session1/"

Since the "session1" in the folder paths above can be replaced with whatever you need, you can have as many as you want too. It might not seem much of a need but synchronising the SASUSER folders every now and again can give you a more consistent set of settings across each session, all without intrusive pop up boxes or extra messages in the log too.

Useful keyboard shortcuts for managing the window sizes of Windows applications

Maximising and minimising windows is all part and parcel of using window-based user interfaces, so it's nice to know that there are keyboard shortcuts that reduce the need to use your mouse all the time. Here are a few that work on Windows:

Alt+Space+N   Minimise

Alt+Space+X   Maximise

Alt+Space+R   Restore (set to default)

Uses for symbolic links

UNIX (and Linux) does a wonderful trick with its file and folder shortcuts; it effectively treats them as file and folder transporters that transfer associate a file or folder that exists in one folder hierarchy with another, and it is treated as if it exists in that hierarchy too. For example, the folder named images under /www/htdocs/blog can have a link under /www/htdocs/ that makes it appear that its contents exist in both places without any file duplication. For instance, the pwd command cannot tell a folder from a folder shortcut. To achieve this, I use what are called symbolic links and the following command achieves the outcome in the example:

ln -s /www/htdocs/blog/images /www/htdocs/images

The first file path is the destination for the link, while the second one is that for the link itself. Once, I had a problem with Google Reader not showing up images in its feed displays, so symbolic links rode to the rescue as they did for resolving a similar conundrum that I was encountering when editing posts in my hillwalking blog.

Adding a new hard drive

Having during the week obtained a new 320 GB hard drive, today I am adding it to my system after yesterdays scare with a PSU. As with any such item, you need to format and configure it to work with your operating system, be it Windows, Linux or whatever. Good old Partition Magic can help with this (I have version 7 from the Powerquest days) but Windows XP (Professional, anyway) does offer its own tool for the job: the Disk Management console. Unfortunately, it's a bit difficult to find. The easiest way to get to it is to type diskmgmt.msc into the Run command box. Otherwise, it is a matter of setting your Start Menu to show the Administrative Tools group (Taskbar and Start Menu properties> Start Menu tab > Customise > Advanced tab) and accessing through the computer Management console, for which there is a shortcut in this group. Of course, you need to have administrator access to your PC to do any of this.
