Pricing Shifts between CreateSpace, IngramSpark, and KDP Print
Before I go all stabby, though, let’s gather all the information. For an apples-to-apples comparison, I’m setting the CreateSpace price of Spilled Mirovar to $6.99, same as KDP Print and IngramSpark. We really need to make two comparisons. CreateSpace’s Expanded Distribution (CSED) is analogous to IngramSpark, and CreateSpace’s Amazon service is migrating to KDP Print.

FreeBSD lockless algorithm - seq
Those days locking algorithms are critical for operating systems, especially in a multi-threaded world. With time it turns out that classical locks, like mutex, are performance costly. Even when we are using techniques like having reads and writes mutex, synchronizing the state between CPUs can be costly. To optimize some cases, the lockless algorithm started to be used.
There are multiple places in the kernel where we need to read some variables very often, but there is a small number of cases when we write to them. For such cases, the seq interface was created. [...]

How does the process title works?
Let's start by defining what the title of a process is - in this article, we will understand the name reported by ps(1)/top(1). When we are creating a new process using fork(2) the process inherits the name from its parent. In the scenario when we call exec(2) function we also pass the list of the arguments for a process, which will be treated as a process title. What if we would like to change the title of the process when it's running? It turns out that many operating systems do it in a different way. In this article we will discuss how open source operating systems like FreeBSD, Linux, OpenBSD, NetBSD, and DragonFlyBSD do it.

Users are able to declare disk images as ‘raw’ or ‘qcow2’ using either vmctl and vm.conf. The default disk image format is ‘raw’ if not specified.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
