Random thoughts about random subjects… From science to literature and between manga and watercolours, passing by data science and rugby; including film, physics and fiction, programming, pictures and puns.
I have been using GSuite in the last year or so at work. In general it seem to be fine, good usage of the email capabilities provided by Gmail and the storage, together with shared drives, and things like that are fine.
Calendar is ok and it does the work, however there was a very irritating thing when being invited to see other colleague’s calendars and/or subscriptions to them. On the one hand it is useful to see calendar availability, but I don’t want to see all of those calendars on my mobile device, or the Calendar app on my Macbook all the time.
A quick solution would be to “uncheck” the unwanted calendars on your device, but… The problem is, when you uncheck those calendars, they’re still there. You may not see them, but boy, you do continue getting reminders, notifications, alerts – and most (all?) of the time they are not even for me to act on!
So if you require to remove these extra calendar, bit still access then via the web and Google apps then do the following:
I have been considering moving a considerable photo collection I have amassed for a few years now after getting my first digital camera. I used to take a lot of pictures before that with a beloved Cannon SLR that belonged to my father. Sadly that camera got stolen in a holiday in Cancun… but that is a story for another time.
Anyway, I used to use Picasa to organise my photos into albums and upload or share some with friends and family. Picasa was superseded by Google Photos and I never quite liked losing some control on where my photos went.
I have been an iOS user of Apple Photos — I like the simplicity of taking a picture and it being part of an album that I keep in my phone until I clean the album… I did try using the Mac version, but as I said I never liked just getting a soup of pictures. I wanted to keep them in the album/folder hierarchy I curated myself. It is until now that I have found a way for Apple Photos to respect my hierarchy. Here is what you need to do:
Find the place where your pictures are organised folders and drag the top folder onto the Photos App icon in the Dock. It does not matter if the App is running
NOTE: Do not drag it to the Photo App window. If you do, the applications behaves in a different way and you will end up with a soup of photographs.
At the top of the window you will see a checkbox that reads “Keep Folder Organisation” on the top right (see the screenshot above)
Click the blue button, “Import All New Items”
Et voilà! Your imported photos will show up in an organised folder in the sidebar.
UPDATE – On April 1st 2021 MacTex released the 2021 version of the software. In this new version the code is universal and works well with both Intel and Apple silicon:
All binaries in MacTeX-2021 are universal, with code for both Arm and Intel processors. The same source code is used to compile both types of code, so Apple’s Arm and Intel machines are on exactly the same footing.
I have been playing with a new M1 MacBook Air and I must admit it is quite an experience. It is a very responsive fast little machine with no fan! Great so far. I have been looking into using a lot of the software that enables my own work and that includes, among other things, LaTeX.
I had a look at the MacTeX pages about ARM and it was great to see that the view is that Rosetta 2 would have me covered… I am not ready to go native just yet… So after installing the software I was surprised to get some messages in my terminal telling me that pdflatex could not be found.
After playing with things for a bit I found that the location of the files ended up in a folder indicating the architecture of the machine. So if you are looking for things in your machine, please take look for things in the following path:
I have had to point some other software to this location and things seem to be working fine. I have not looked into the implication of other things such as the conversion of jupyter notebooks into LaTeX documents…. I will do and report back.
I have been using LibreOffice on and off for a few years now and generally I think it is a great alternative to the MS Office offering. It does the tasks that are required and the improvements over different versions have been steady and useful
I had however a very strange experience in which dialogue boxes and other windows such as alerts and messages just showed blank text. It was obvious that there was some important information in them, but it was not possible to read them. In some cases it was ok… I mean I knew here the “OK” button was expected to appear, or where “Cancel” should be placed. However, it was an annoying (at best) and limiting (at worst) exoperience.
After digging in a bit I realised what the problem was. The fonts that were supposed to be showing were at fault. The culprits were as follows:
After removing these two fonts from ~/Library/Fonts/ everything went back to normal. I hope this helps in case you are having a similar issue.
Have you tried taking a screenshot in your Mac and are annoyed at having to wait for the floating thumbnail – in other words you wait for 5 seconds before the screenshot becomes a file? Well here you can find out how to get rid of that.
Follow these steps:
1) Type CMD + SHIFT + 5 2) Click OPTIONS 3) Uncheck “Show Floating Thumbnail” 4) Et voilà!
“Why do I have to use backslashes (\) in Windows, but forward slashes (/) in everything else?” This is a question that I have been asked by a number of people over the years and I have been meaning to write something about it for a long time now.
It seems that Windows is really the odd one out as Linux, OS X and even Android uses forward slashes. It seems that the cause of this annoying (at times) difference is due to accidental events.
In the 1970s, Unix first introduced the forward slash to separate entries in a directory path. So far so good. In the meantime, the initial version of MS DOS did not even support the use of directories… and we are talking early 80s here! At the time, IBM has the main contributor to Microsofr utilities and they used the forward slash as a flag or switch character (In Unix we use a hyphen for this). You can still see a vestigial tail in some commands… Think dir /w for example.
The next version of MS DOs started support for directories and to keep compatibility, IBM expected to continue usage of / as a flag and as such the alternative for directory path separation, Windows started using \. Once you start using this in your own environment, who cares what other people use in their operating systems!! Right? In that way, in Windows the use of the different slashes tells you if you are running an option (/) or a directory path (\).
I have recently taken Mojave for a spin and I am really happy with the changes in the new OS. I know it is merely eye-candy, but I really like the dark theme. Things have been working well, but I came across a nagging issue with my MagicMouse:
For some reason the secondary click would simply not work. I had made sure the settings were enabled by making sure that the “Secondary Click” option was ticked (see screenshot below). I tried ticking it on and off, restarting the machine, deleting the mouse and reconnecting it… nothing had worked…
Finally I decided to take a look at some of the plist files and here is my solution to this problem:
Hello everyone! I am very pleased to take a question from John who got in touch with Quantum Tunnel using the form here. John’s favourite scientist is Einstein and his question is as follows:
In Mac mail I cannot delete unwanted email addresses. I have done the routine of deleting all addresses from the previous receiptant list, but when starting a new email unwanted addresses appear.. Any help is appreciated. Thanks, John
John is referring to the solution I provided in this earlier post. Sadly, the list of his lucky friends/colleagues/family (delete as appropriate) he has email recently persists even after clearing the “Previous Recipients” as explained in the post before.
There may be a way to force the clearing of these persistent email address:
Quit Mail and Address Book (in case the latter is open)
I was looking for the location of iBooks files (including ePub, PDFs and others) so that I can curate the list of manually exported files. Finding iBooks in my Mac should not be a difficult task, although it took a few minutes. I thought of sharing that here in the blog for future reference and in the hope that some of yo may find it useful.
We will use the Terminal, as doing things from Finder tends to redirect us. A first place to look into is the following one:
It is not unusual to come across encoding problems when opening files in Python 3. The subject matter is a large topic of discussion, and here I am providing some quick ways to deal with a typical encoding issue you are likely to encounter.
Say you are interested in opening a CSV file to be loaded into a pandas dataframe. If the stars align and the generator of your CSV is magnanimous, they may have saved the file using UTF-8. If so you may get away with reading the file (here called my file.csv) as follows
import python as pd
df = pd.read_csv('myfile.csv')
You should in principle pass a parameter to pandas telling it what encoding the file has been saved with, so a more complete version of the snippet above would be:
import python as pd
df = pd.read_csv('myfile.csv', encoding='utf-8')
What happens when you don’t know what encoding was used to save the file? Well, you can ask, but it is very unlikely that the file generator know… What to do? Well there are some libraries that can be helpful.
Install the chardet module as follows from the terminal
