How to make snaps faster | Ubuntu

A great user experience is (or at least, should be) an integral part of any software that involves user interaction. On the desktop, this starts with the application launch, and continues through the session. The overall time to completion of tasks as well as interactive responsiveness are a core element in this journey.

If you’re a snap developer or publisher, the topic of speed may arise for various reasons. The differences in the overall architecture and principles of operation of snaps, in comparison to software deployed as Deb or RPM packages, can sometimes lead to a slower experience. This goes against the prime directive of desktop usage. In this article, we want to show you a number of methods and tools you can use to make your snaps snappy.

Ian's TechBlog: Installing Ubuntu Core onto 64-bit Bare Metal

I have a re-purposed AMD64 laptop motherboard, ready to become an experimental Ubuntu Core server.

It's in fine condition. You can see that it boots an Ubuntu LiveUSB's "Try Ubuntu" environment just fine. Attached to the motherboard is a new 60GB SSD for testing. The real server will use a 1TB HDD.

But Ubuntu Core doesn't install on bare metal from a Live USB. It's still easy, though.

Using Salsa with contrib and non-free - linux.codehelp.co.uk

OK, I know contrib and non-free aren't popular topics to many but I've had to sort out some simple CI for such contributions and I thought it best to document how to get it working. You will need access to the GitLab Settings for the project in Salsa - or ask someone to add some CI/CD variables on your behalf. (If CI isn't running at all, the settings will need to be modified to enable debian/salsa-ci.yml first, in the same way as packages in main).

MySQL date format – what you need to know | FOSS Linux

MySQL is derived from ‘My’- the cofounder’s daughter and SQL- Structured Query Language. It is an open-source type of relational database management system. This relational database system helps organize data into relatable tables, thereby enabling structural relations of different data sets.

MySQL date is one of the temporal data types that can manage data values alongside other data types such as numeric data types, String data types, Boolean data types, date and time, and spatial data types.

The DATE_FORMAT() function is used in MySQL to format date using the specified format value. For instance, if a date is provided, the function will format it concerning the specified parameters.

snap Vs .deb Package

As the number of Linux applications grows, so does the concern about security. Even though there are few recorded Linux attack incidents, it is conceivable to be attacked by viruses, hackers, or malware.

Because Linux is open-source, those problems are fixed faster, and the community may contribute to maintaining the Linux World ready for any bug or virus that appears. When installing a vulnerable application (or app), it may require libraries that are no longer accessible on that distro’s version.
In this article, we’ll go through the key distinctions between.deb and.snap packages.
