Debian vs Ubuntu in 2020- The Ultimate Showdown

Filed under
Debian
Ubuntu

As a computer software distribution package, Ubuntu and Debian are utilized in two ways...

Desktop Operating System
Server

Although they are similar in many ways, they have their differences. Ubuntu is based on the testing branch of Debian and often, Debian involves too many manual works and so it is not recommended for beginners. While Ubuntu is easy to use for beginners, it is not as stable as Debian in its built. Let us have a comparison between Debian vs Ubuntu.

Ubuntu MATE 20.04.1 for Raspberry Pi Now Has a Second Beta Ready for Testing

Filed under
Ubuntu

Martin Wimpress published a new beta version of the upcoming Ubuntu MATE 20.04.1 images for Raspberry Pi devices, which you can download and test right now on the tiny computer.

Ubuntu MATE 20.04.1 for Raspberry Pi promises major new features, such as support for the latest Raspberry Pi 4 SCBs, better graphics, experimental USB booting, basic rendering for the Firefox web browser by default, support for the rpi-eeprom utility for updating the Raspberry Pi 4 bootloader EEPROM, and a new configuration tool.

Based on the recently released Ubuntu 20.04.1 LTS (Focal Fossa) operating system, the upcoming Ubuntu MATE 20.04.1 for Raspberry Pi release is now in its latest stages of development, with a second beta version ready for public testing.

Since beta 1, the team fixed Wi-Fi issues that occurred on the first boot during the initial setup wizard and dropped the gpu_mem memory option that lets you specify how much memory the GPU can use from the config.txt file for better performance.

The beta 2 is also powered by the same Linux 5.4 LTS kernel used in Ubuntu 20.04.1 LTS, and uses the latest MATE 1.24 desktop environment and most the core apps that are also available in the Ubuntu MATE 20.04.1 LTS release for PCs.

Ubuntu 18.04.5 LTS Released with Linux Kernel 5.4 LTS from Ubuntu 20.04 LTS

Filed under
Linux
Ubuntu

Ubuntu 18.04.5 LTS comes six months after the Ubuntu 18.04.4 LTS point release and two and a half years after the release of Ubuntu 18.04 LTS (Bionic Beaver), which is normally supported until April 2023, though the end of life is planned for April 2028 due to Canonical’s new 10-year support policy.

The good news for those still using Ubuntu 18.04 LTS (Bionic Beaver) is that Ubuntu 18.04.5 LTS brings yet another kernel and graphics stacks bump. This time, it runs the Linux 5.4 LTS kernel and Mesa 20.0.8 graphics stack from Ubuntu 20.04 LTS (Focal Fossa).

  • Jonathan Carter: GameMode in Debian

    About two years ago, I ran into some bugs running a game on Debian, so installed Windows 10 on a spare computer and ran it on there. I learned that when you launch a game in Windows 10, it automatically disables notifications, screensaver, reduces power saving measures and gives the game maximum priority. I thought “Oh, that’s actually quite nice, but we probably won’t see that kind of integration on Linux any time soon”. The very next week, I read the initial announcement of GameMode, a tool from Feral Interactive that does a bunch of tricks to maximise performance for games running on Linux.

Ubuntu 18.04.5 and 16.04.7 LTS Release Candidate ISOs Now Ready for Public Testing

Filed under
Ubuntu

After last week’s release of Ubuntu 20.04.1 LTS as the first point release in the Focal Fossa series, Canonical is now working on new point releases for its long-term supported Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 16.04 LTS (Xenial Xerus) operating system series.

Your reaction right now would be like… wait, Ubuntu 16.04.7? Why? Aren’t there only five point releases during the life cycle of an Ubuntu LTS series? Yes, you’re right, Canonical usually bakes only five ISO point releases for each LTS series, but sometime they have to release emergency ISOs because of some nasty bugs.

It happened last year with Ubuntu 16.04.6 LTS and Ubuntu 14.04.6 LTS (now ESM) to patch a critical security vulnerability in the APT package manager, which allowed attackers to execute code as root or possibly install malicious apps and crash the system.

AMD Ryzen Embedded SBC Review with Ubuntu 20.04

Filed under
Reviews
Ubuntu

DFI GHF51 Ryzen Embedded SBC runs about as well in Ubuntu 20.04 as it does in Windows 10. Everything basically works and performs well. Our testing shows AMD Ryzen Embedded R1606G processor to offer slightly better performance than the top of the line Intel Gemini Lake Pentium J5005 processor.

I also had one of the same issues as in Windows: one Seagate USB hard drive would not work reliability at all with transfer stalled. That’s probably just a hardware incompatibility, as the drive works with other platforms, and other USB storage devices achieve normal performance when connected to DFI SBC. I also noticed some artifacts with one 3D graphics benchmark, but those did not show up in other 3D accelerated programs.

DFI GHF51 is an impressive piece of hardware as it packs lots of CPU and GPU power in a form factor similar to Raspberry Pi 4 SBC. I’d like to thank DFI for sending a review sample. If you plan to buy in large quantities to integrate the board into your product, you could contact the company via the product page. It’s used to be available as a sample on the company’s DFI-ITOX online store for $378, but it has been taken down since last time.

  • Are universities spending enough on cybersecurity? [iophk: Windows TCO]

    Such attacks “will absolutely continue”, said Mark Ford, who leads higher education risk and financial advisory services for the audit firm Deloitte. As higher education becomes known as an “easy target”, this increasingly “attracts the bad guys”, he explained.

    The threat comes not just from criminals seeking money. Universities now house arguably the most valuable secrets on earth – plans for a coronavirus vaccine – putting them in the sights of state-backed [cr]ackers. In July, UK, US and Canadian intelligence services warned that Russian groups were attempting to target Covid-19 vaccine research and development.

    This raises the question: are universities doing enough to defend themselves against [cr]acking?

    If you want to create a truly open standard, you _need_ to make it simple.

    There are no exceptions to this rule. When a standard becomes harder to fully implement than what your average motivated programmer can do in two months (max!), it _shouldn't_ be considered "open" anymore.

  • In Which COVID-19 Misinformation Leads To A Bunch of Graphs Made With Rust

    A funny — and by funny, I mean sad — thing has happened. Recently the Kansas Department of Health and Environment (KDHE) has been analyzing data from the patchwork implementation of mask requirements in Kansas. They came to a conclusion that shouldn’t be surprising to anyone: masks help. They published a chart showing this. A right-wing propaganda publication got ahold of this, and claimed the numbers were “doctored” because there were two-different Y-axes. I set about to analyze the data myself from public sources, and produced graphs of various kinds using a single Y-axis and supporting the idea that the graphs were not, in fact, doctored. Here’s one graph that’s showing that: In order to do that, I had imported COVID-19 data from various public sources. Many states in the US are large enough to have significant variation in COVID-19 conditions, and many of the source people look at don’t show county-level data over time. I wanted to do that.

  • Basics of Working with the SQLite Database in Python

    A database is one of the most useful and popular files for storing data; they can be used to store any kind of data, including text, numbers, images, binary data, files, etc. SQLite is a relational database management system based on the SQL language. It is a C library, and it provides an API to work with other programming languages, including Python. It does not require a separate server process to be run as needed in large database engines like MySQL and Postgresql. It is swift and lightweight, and the entire database is stored in a single disk file, which makes it portable like CSV or other data storage files. Many applications use SQLite for internal data storage, mainly in environments like mobile devices or small applications.

    Perl 7 has been announced as the next direction of Perl development. My previous blog post explored at a high level the risks and benefits of the announced direction, as well as those of a more incremental proposal.

I would like to explore each of the arguments presented for this design choice.

  • SSH vs. kubectl exec

    There’s a lot of similarities between SSH and kubectl, and both have their strengths and weaknesses. While SSH is architecturally set in stone, higher-level software can learn a thing or two from Kubernetes about centralized configuration when managing a fleet of machines. See Teleport for an example of how this can be done. SSH could also borrow the credential management approach from kubeconfigs (i.e. “put all my client creds and server info into one file that I can copy around”).

    kubectl could improve on its non-shell features like port forwarding and file transfer. It’s raw data throughput is also lacking, which precludes it from becoming a transport-layer protocol like SSH. In practice, these tools are complementary and get used for different tasks, it’s not “one or the other”. I hope this post helped you learn something new about both!

  • Benign Data Races Considered Harmful

    The series of posts about so called benign data races stirred a lot of controversy and led to numerous discussions at the startup I was working at called Corensic. Two bastions formed, one claiming that no data race was benign, and the other claiming that data races were essential for performance. Then it turned out that we couldn’t even agree on the definition of a data race. In particular, the C++11 definition seemed to deviate from the established notions.

  • Micronaut 2.0 Full-Stack Java Framework Released

    The Micronaut framework uses Java's annotation processors, which work with any JVM language that supports them, as well as an HTTP server and client built on the Netty non-blocking I/O client server framework. To provide a programming model similar to Spring and Grails, these annotation processors pre-compile the required metadata to perform DI, define AOP proxies, and configure applications to run in a low-memory environment, the company says. Many of the APIs in Micronaut were "heavily inspired" by Spring and Grails," which was by design and aids in bringing developers up to speed quickly," the company says.

  • Understanding computer vision and AI, part 1

    An active area in the field of computer vision is object detection, where the goal is to not only localize objects of interest within an image but also assign a label to each of these objects of interest. Considerable recent successes in the area of object detection stem from modern advances in deep learning, particularly leveraging deep convolutional neural networks. Much of the initial focus was on improving accuracy, leading to increasingly more complex object detection networks such as SSD, R-CNN, Mask R-CNN, and other extended variants of these networks. While such networks demonstrated state-of-the-art object detection performance, they were very challenging, if not impossible, to deploy on edge and mobile devices due to computational and memory constraints. This greatly limits the widespread adoption for a wide range of applications such as robotics, video surveillance, autonomous driving where local embedded processing is required. [...] Model Evaluation is an integral part of the model development process. It helps to find the best model that represents our data and how well the chosen model performs on unseen data. To improve the model we tune the hyper-parameters; parameter that determines the network structure (number of neurons in the network, network activation functions) or training parameter (gradient descent learning rate, adding parameters like momentum in the weight update rule). Tuning those parameters is an inevitable and important step to obtain better performance. Methods like GridSearch and RandomizedSearch can be used to navigate through the different parameters.
