How to encrypt files with gocryptfs on Linux

Saturday 17th of August 2019 03:07:20 PM
Gocryptfs is a Filesystem in Userspace (FUSE)-mounted file-level encryption program. FUSE-mounted means that the encrypted files are stored in a single directory tree that is mounted, like a USB key, using the FUSE interface. This allows any user to do the mount—you don[he]#039[/he]t need to be root. Because gocryptfs encrypts at the file level, synchronization operations that copy your files can work efficiently on each file.

  • Cantor and the support for Jupyter notebooks at the finish line

    Hello everyone! It's been almost three weeks since my last post and this is going to be my my final post in this blog. So, I want to summarize all my work done in this GSoC project. Just to remember again, the goal of the project was to add the support for Jupiter notebooks to Cantor. This format is widely used in the scientific and education areas, mostly by the application Jupyter, and there is a lot of content available on the internet in this format (for example, here). By adding the support of this format in Cantor we’ll allow Cantor users access this content. This is short description, if you more intersted, you can found more details in my proporsal. [...] This is all for the limitations, I think. Let's talk about future plans and perspectives. In my opinion, this project has reached its initial goals, is finished now and will only need maintenance and support in terms of bug fixing and adjustment to potential format changes in future. When talking more generally, this project is part of the current overall development activities in Cantor to improve the usability and the stability of the application and to extend the feature set in order to enable more workflows and to reach to a bigger audience with this. See 19.08 and 18.12 release announcements to read more about the developments in the recent releases of Cantor. Support of the Jupyter notebook format is a big step into this direction but this not all. We have already many other items in our backlog like for the UX improvements, plots integration improvements going into this direction. Some of this items will be addressed soon. Some of them are something for the next GSoC project next year maybe? I think, that's all for now. Thank you for reading this blog and thank you for your interest in my project. Working on this project was a very interesting and pleasant period of my life. I am happy that I had this opportunity and was able to contribute to KDE and especially to Cantor with the support of my mentor Alexander Semke.

  • My Open-Source Activities from January to August 2019

    Debian is a general-purpose Linux distribution that is widely used on the planet. I am a Debian Developer who works on packages related to Android SDK and the Java ecosystem. I started a new package in an attempt to build the Android framework android.jar using the upstream build systems involving Ninja, Soong and others. Since the beginning we have been writing our own (very simple) makefiles to build the binaries in AOSP because their build logic tends to be simple and straightforward, until we worked on android.jar. Building it requires digging in so much code that it became incredibly hard to maintain, which is why we still haven’t brought in any newer version since android-framework-23. This is problematic as developers can’t build any apps that target Android 7+. After a month of work, this package is finally done. After all its dependencies are packaged in the future, it will be good to upload. This is where the students of Google Summer of Code (GSoC) come in!

  • Dive into the life and legacy of Alan Turing: 5 books and more

    Another well-known fact about Turing was his conviction for "gross indecency" because of his homosexuality, and the posthumous apology and pardon issued over more a half a decade after Turing’s death.

Collectively, these books cover his life, both professional and personal, and work others have done to build upon Turing’s ideas. Individually, or collectively, these works allow the reader to learn who Alan Turing was beyond just a few well-known, broad-stroke themes.
