Wikpedia puts it nicely:
"The concept of concurrent computing is frequently confused with the related but distinct concept of parallel computing,[3][4] although both can be described as “multiple processes executing during the same period of time”. In parallel computing, execution occurs at the same physical instant: for example, on separate processors of a multi-processor machine, with the goal of speeding up computations—parallel computing is impossible on a (one-core) single processor, as only one computation can occur at any instant (during any single clock cycle).[a] By contrast, concurrent computing consists of process lifetimes overlapping, but execution does not happen at the same instant. "
A cpu (core) can only do one thing at a time. When you have multiple cores you can do multiple things at the same time. Multitasking in programming sense is a bad term, it’s a term more for the masses.
Bit simplified:
- concurrency: you seem to be doing multiple things at the same time. In reality they are run little by little one after another. Doesn’t really speed things up.
- parallelism: you actually run multiple things at the same time (multiple cpus/cpu cores required). If the code scales properly or is designed to truly run in parallel the speed up is relative to the number of cpus available.
Edit: It’s much more complex subject then I’ve presented here.
9·28 days agoExcellent article. That’s why I use OSS first and foremost as they don’t have the incentive to bring in € instead they are more focused on a quality product.

In the EU this kind of automatic opting-in to marketing/data sharing is against the GDPR as it requires explicit consent from user/customer. I’m in the EU and have those settings but they were both toggled off, as expected.
8·2 months agoI stand corrected. I use Tumbleweed so have not kept up to date on that front.
OpenSuse is already by itself a well rounded distro. It supports multiple desktops out-of-the-box, is highly customizable so it doesn’t really need forks.
SUSE Linux Enterprise isn’t really a fork. OpenSuse Leap is to SLE a bit like Fedora is to Red Hat i.e. the community version which is then frozen at some point to build SLE.
It is. It’s a rolling release so it has the latest packages. It’s not bleeding edge like arch. All software goes thru an automatic testing in OpenQA before they are allowed in the repo so there’s some quality control. It’s also very stable.
I’m on the Other category, both for home and work. I use Tumbleweed in both.
I’m in the EU and that section in the settings isn’t even there. I guess they aren’t doing it here, for now at least. Probably due to GDPR.

Have you tried Okular?
I use that myself though haven’t sent a sms/mms in like > 10 years. Anyhow FOSS > stock spyware any day. The fossify project has many other useful tools as well.
