To Ubuntu or to Kubuntu

Ubuntu

Within four days, I’ve reformatted my hard drive and installed Ubuntu and Kubuntu in quick successions…twice. So that’s a total of four Linux installations in four days. Once again, I was haunted by the ghost of indecision. Should I go for Ubuntu with the clean, minimalistic Gnome, or embrace Kubuntu with the fancy, aesthetic KDE?

My First Two Months With Ubuntu

Filed under
Ubuntu

It’s been a little over two full months that I’ve been using Ubuntu Linux as my sole operating system (cold turkey switch from Windows) and I think it’s about time to share some thoughts, some links, and hopefully a little knowledge that I’ve picked up along the way.

Earlier this month I covered Ubuntu's Migration Assistant, which is one of the features that will be found in Ubuntu 7.04 Feisty Fawn. The migration-assistant is designed to make it very easy for Microsoft Windows converts to jump into the Ubuntu world by automatically transferring files and settings.

Ubuntu Restricted Drivers Manager

Ubuntu

When trying out an Ubuntu daily LiveCD yesterday I noticed the new Ubuntu Restricted Drivers Manager. This manager makes it incredibly easy to manage the binary blob drivers. By default are the ATI/AMD and NVIDIA drivers, and from there you can literally install the drivers almost instantly. It should be very nice for new users!

The Visual History of Ubuntu

Filed under
Ubuntu

While Debian has been around for over a decade, Gentoo for five years, and Mandriva/Mandrake for nearly nine years, in less than three years of existence Ubuntu has received the most attention and generated the greatest amount of publicity in the Linux limelight. Why is that?

Programming: mmap. Python and More

  • Making the Most of your Memory with mmap
    Sometimes it seems that we have nearly infinite memory resources, especially compared to the tiny 48K RAM of yesteryear’s 8-bit computers. But today’s complex applications can soak up megabytes before you know it. While it would be great if developers planned their memory management for all applications, thinking through a memory management strategy is crucial for applications with especially RAM intensive features like image/video processing, massive databases, and machine learning. How do you plan a memory management strategy? It’s very dependent on your application and its requirements, but a good start is to work with your operating system instead of against it. That’s where memory mapping comes in. mmap can make your application’s performance better while also improving its memory profile by letting you leverage the same virtual memory paging machinery that the OS itself relies on. Smart use of the memory mapping API (Qt, UNIX, Windows) allows you to transparently handle massive data sets, automatically paging them out of memory as needed – and it’s much better than you’re likely to manage with a roll-your-own memory management scheme. Here’s a real-life use case of how we used mmap to optimize RAM use in QiTissue, a medical image application. This application loads, merges, manipulates, and displays highly detailed microscope images that are up to gigabytes in size. It needs to be efficient or risks running out of memory even on desktops loaded with RAM.

  • 13 Project Ideas for Intermediate Python Developers
    Learning the basics of Python is a wonderful experience. But the euphoria of just learning can be replaced by the hunger for hands-on projects. It’s normal to want to build projects, hence the need for project ideas. The problem though is that some projects are either too simple for an intermediate Python developer or too hard. This article will suggest projects you can work on as an intermediate Python developer. These project ideas will provide the appropriate level of challenge for you.

DebConf20 Conference to Be Hosted in Haifa, Israel, for Debian GNU/Linux 11

A port city built in tiers, Haifa is found in the northern area of Israel, extending from the Mediterranean sea till the north slope of the Carmel Mountain National Park. Haifa it's the third-largest city in Israel after Jerusalem and Tel Aviv, and it is close to the biblical city Nazareth where Jesus studied and prayed. In 2020, the Debian Project will celebrate 12 years since the first DebConf Debian developer conference, so they decided to choose Israel instead of Lisbon, Portugal, for next year's DebConf20 event despite the extensive discussions between the DebConf team and committee due to Israel's political system.

Ubuntu Leftovers

  • Debug ACPI DSDT and SSDT with ACPICA Utilities
    Using acpidbg on Ubuntu 18.04 x64 can be quite handy; however, the Linux kernel with ACPI_DEBUGGER is not always available, such as on Ubuntu for ARM. In such cases, acpica also provides a set of utilities, named acpica-tools, for ACPI debugging.
  • NVIDIA Jetson Nano is a $99 Computer Built for AI, Powered by Ubuntu
    Sold as a complete compute solution, the Jetson Nano Developer Kit wants to let embedded designers, researchers, and DIY makers harness the power of AI, all at an affordable price. A NVIDIA’s JetPack SDK provides a ‘complete desktop Linux environment based on Ubuntu 18.04 LTS’, replete with accelerated graphics, NVIDIA CUDA toolkit support, and more. NVIDIA say developers will find it “easy” to install leading open-source Machine Learning (ML) frameworks like TensorFlow, Caffe and Keras. Frameworks for computer vision and robotics development like OpenCV and ROS are also available via the SDK. The JetPack 4.2 SDK [shipped on the microSD card] provides a complete desktop Linux environment for Jetson Nano based on Ubuntu 18.04 with accelerated graphics, support for NVIDIA CUDA Toolkit 10.0, and libraries such as cuDNN 7.3 and TensorRT 5,” Nvidia says of the nimble Nano dev kit. But how powerful is it?
