DNF v.s. Yum

Filed under
Red Hat
HowTos

A lot has been said on fedora-devel in the last few weeks about DNF and Yum. I thought it might be useful to contribute my own views, considering I’ve spent the last half-decade consuming the internal Yum API and the last couple of years helping to design the replacement with about half a dozen of the packaging team here at Red Hat. I’m also a person who unsuccessfully tried to replace Yum completely with Zif in fedora a few years ago, so I know quite a bit about packaging systems and metadata parsing.

Recovering Linux after catastrophic deletion

Filed under
GNU
Linux
HowTos

A recurring Linux joke / horror story is running the command rm –rf /. Imagine if it actually happened? What would or could you do to recover?

Linux specialist Kyle Kelley recently decided to see what happened if he launched a new Linux server and ran rm –rf / as root.

This command is the remove (delete) command, with the flags –rf indicating to run recursively down all folders and subfolders, and to force deletion even if the file is ordinarily read-only. The / indicates the command is to run from the top-most root directory in Linux.

KDE

Before you follow my instructions to install Plasma 5 on your system, keep in mind that Plasma 5 is under heavy development and the stable release has not been made. Since it’s in development stage, there are (as expected) issues. Some of the issue you should be aware of include the missing wallpaper, icons may stop working now and then and Plasma Network Manager is missing as well.

Build your own distro part two

Filed under
GNU
Linux
HowTos

Canonical provides a minimal Ubuntu install CD. It’s smaller than the regular installation ISO and it installs a minimal version of the distribution. At its most basic, it gives the user a command line, network connectivity and not much else. From this bare-bones beginning, it’s possible to selectively add components while leaving out most of the cruft that tends to come with a standard distribution.

Android One: Let us fill you in on Google’s big game

India is now the world’s third largest Internet market and “on a bullet train to become the second”. But even when we become the second with around 300 million Internet users, India would still have over 75 per cent of the population that has no access to this so-called information superhighway. It is this chunk of population that will form the “next billion” which companies like Nokia, and now Google, has been talking about. And it is this next billion that Google thinks will line up to buy and good smartphone that is also affordable. Read more

Mesa Gets Closer To Having OpenGL 4.0 Tessellation Support

A significant patch-set was published on Saturday night that implements the driver-independent bits of OpenGL 4's ARB_tessellation_shader extension inside Mesa. The tessellation support has been one of the big pieces missing from Mesa's OpenGL 4 implementation and fortunately it's getting close to mainline. Chris Forbes of Intel published fifty-six patches this weekend that implement the driver-independent portions of the extension inside Mesa. Of course, the driver portions still need to follow for it to be useful. Read more

Small Console Menu Utilities

One of the great strengths of Linux is the whole raft of weird and wonderful open source utilities. That strength does not simply derive from the functionality they offer, but from the synergy generated by using them together, sometimes in conjunction with applications. The Unix philosophy spawned a "software tools" movement which focused on developing concise, basic, clear, modular and extensible code that can be used for other projects. This philosophy remains an important element for many Linux projects. Good open source developers writing utilities seek to make sure the utility does its job as well as possible, and work well with other utilities. The goal is that users have a handful of tools, each of which seeks to excel at one thing. Some utilities work well on their own. This article looks at four tiny utilities that offer menu facilities. They get virtually zero coverage in the Linux press, so you may not have heard of them before, but they are well crafted and might just fit the bill. Read more

Samsung ship SM-Z130H budget Tizen Smartphones to India for R&D Purposes

According to a Zauba International shipping manifest, Samsung have shipped 150 of these units from South Korea to India for R&D and Evaluation purposes, which is a fair amount for an R&D unit to continue its work with. We have been tracking two budget Tizen based Smartphones lately, the SM-Z130H & SM-Z130E, with various parts being shipped to India every couple of months or so, but this is one of the largest shipments that we have seen so far.
