Allow people to filter in a shared read-only excel file on Sharepoint

I have an excel file that is hosted on Sharepoint and accessible to anyone with a link. I don’t want anyone to be able to change the data in the file, so I’ve removed Edit access for everyone but me. The tricky thing is that I do want people to be able to filter in […]

Catalina System Preferences shows update badge, but no updates are available

I just upgraded to Catalina, and now my System Preferences icon in the Dock shows an update badge with an annoying little “1” in it: So far, so similar to this old question. Unlike that question, though, when I open up System Preferences, the Software Update icon has the same update badge, so I can […]

Upload newly installed graphics drivers from command line, and switch afterwards

I have installed the nvidia driver recommended by [1] using the nvidia graphics ppa [2] but the computer freezes if I log out of my profile; not even a Ctrl+Alt+Function key responds. I do a hard power-down then. Afterwards it works all as expected. In the future, though, I would avoid the hard-power down. I […]

Some of these are clients they’ve been working with for months and others are brand new prospects that they’re reaching out to for the first time. They don’t receive […]

How to log details of certificates for each connection in OpenVPN?

I’m running an OpenVPN-server for some IoT-devices and many of those devices need their certificates replaced because the old ones expire. Updating those certificates is a fragile, manual process using slow mobile connections and additionally those devices can be accessed using OVPN only. For this reason, I want to make extra sure that the certificates […]

Reference request: a survey of (linear) Krein-Rutman theory

I’m looking for a survey article or book chapter where a rather exhaustive treatment of the Krein-Rutman theory of positive linear operators an ordered Banach spaces is given. Motivation. Some explanation is probably required. Classicly, one finds two types of “Krein-Rutman theorems”, and many versions thereof, in the literature: Let $X$ be a real Banach […]

Music stops when the screen is off

After selecting a music file to open in file explorer in a floating mode, the music stops as soon as the phone is locked. I whitelisted both the player and explorer in battery saver settings but no luck. Playing music in the music player itself isn’t creating this problem, though.

Pairwise merging of files in parallel until only 1 file left over

I’d like to combine a bunch of language model (LM) count files using SRILM’s ngram-merge program. With that program, I could combine a whole directory of count files, e.g. ngram-merge -write combined_file — folder/*. However, with my amount of data it would run for days, so I’d love to merge the files in parallel! The […]

How Can I Add A Dual-Boot Installation of PrimeOS to my GRUB?

Recently, I installed PrimeOS (Standard version) onto my computer in its own ext4 partition. During the installation it asked if I would like to install GRUB2, obviously unaware that my computer already had it. This attempt to install Prime is only just after a nasty encounter with Android-x86, where a new GRUB was installed without […]
