With a flick of the wrist, the tablet turns into ... an additional monitor

Hello, attentive habrachitatel. After publishing a topic with photos of the workplaces of Khabrovites, I still waited for a reaction to the β€œEaster egg” in the photo of my cluttered workplace, namely, questions like: β€œWhat is this tablet with Windows and why are there such small icons on it?” The answer is similar to "the death of Koshcheeva" - after all, the tablet (regular iPad 3Gen) in our […]

Making it easy to build Linux from source with UmVirt LFS Packages

Perhaps many of the users of GNU / Linux in the light of recent initiatives of the authorities to create a "sovereign" Internet were puzzled by the goal of insuring against the unavailability of the repositories of popular distributions of GNU / Linux.

And again about the second monitor from the tablet ...

Having turned out to be the owner of such an average tablet with a non-working sensor (the eldest son tried), he thought for a long time where to adapt it. Googled, googled and googled (one, two, Hacker #227), as well as many other recipes involving spacedesk, iDispla and some others. That's just bad luck - I have Linux. Googling some more, I found a few recipes and through a little shamanism I got an acceptable […]

4K: evolution or marketing?

Is 4K destined to become the TV standard, or will it remain a privilege reserved for the few? What awaits providers who launch UHD service? In the BROADVISION analysts' report you will find the answer to these and other questions. At first glance, it may seem that the quality of a television picture is directly dependent on the quantity: the more pixels per square inch, the better. For confirmation, no […]

cmus console player for linux
