Reviews

When it comes to new laptops for the summer of 2018 that are Linux-friendly, the latest-generation Dell XPS 13 with Intel Kabylake-R processor ranks high on that list. Recent in upgrading my main production workstation, I decided to go with the Dell XPS 13 9370 while using Fedora Workstation 28 and it's been a phenomenal combination. Here are my thoughts on the current Dell XPS 13 as well as some benchmarks and other information.

Here's the New Login Screen of Ubuntu 18.10 (Cosmic Cuttlefish) with Yaru Theme

Filed under
Ubuntu

One of the most attractive things about the forthcoming Ubuntu 18.10 operating system, due for release later this fall on October 18, 2018, is its new look and feel, which is provided by the so-called Communitheme that was recently renamed as Yaru, a system-wide theme for Ubuntu Desktop.

As part of this community initiative, Ubuntu 18.10 will get a brand-new look and feel that will make the popular computer operating system more modern, more accessible, and more attractive. And, today we finally have a first look at the Yaru theme on the current Ubuntu 18.10 (Cosmic Cuttlefish) development release.

  • How to be the lazy sysadmin

    The job of a Linux SysAdmin is always complex and often fraught with various pitfalls and obstacles. Ranging from never having enough time to do everything, to having the Pointy-Haired Boss (PHB) staring over your shoulder while you try to work on the task that she or he just gave you, to having the most critical server in your care crash at the most inopportune time, problems and challenges abound. I have found that becoming the Lazy Sysadmin can help.

  • What's in a container image: Meeting the legal challenges

    Container technology has, for many years, been transforming how workloads in data centers are managed and speeding the cycle of application development and deployment.

    In addition, container images are increasingly used as a distribution format, with container registries a mechanism for software distribution. Isn't this just like packages distributed using package management tools? Not quite. While container image distribution is similar to RPMs, DEBs, and other package management systems (for example, storing and distributing archives of files), the implications of container image distribution are more complicated. It is not the fault of container technology itself; rather, it's because container distribution is used differently than package management systems.

  • IBM & Google Launch 'Istio' Cloud Software, but Amazon & Microsoft Skip the Party

    Istio, an open source project backed by IBM, Google, Red Hat and others for connecting, managing and securing Kubernetes containers, hits version 1.0 Tuesday. But can Istio become ubiquitous without support from market leaders Amazon Web Services and Microsoft?

    Istio, also backed by Lyft Inc. and Pivotal , is a "service mesh," picking up where Kubernetes leaves off. Kubernetes provides orchestration to run multiple containers, manage their lifecycle, keep them available and scale them up and down as needed. Istio is software for managing how containers interact with each other.

  • The Istio service mesh hits version 1.0
  • What is Istio? The latest open source project out of Google
  • Istio sets sail as Red Hat renovates OpenShift container ship

    Red Hat is celebrating the 1.0 release of Istio, the open source microservices management project, and the arrival of version 3.10 of its OpenShift software container platform.

    Istio's 1.0 release received mention at Google Cloud Next last week, but the official bits are expected on Tuesday. The software serves as a management mechanism for distributed microservices, providing capabilities like traffic management, service identity and security, policy enforcement and telemetry among apps running across multiple Kubernetes clusters and hosts.

  • IBM, Google, Red Hat push Istio to 1.0 release

    IBM launched Istio along with Google Cloud and Lyft a little more than a year ago. The goal of Istio is to give developers a vendor-neutral way to connect, secure and manage networks of various microservices.

    Managing microservices is a critical issue since enterprises are increasingly built on them. By breaking services and applications into smaller parts developers can be more agile. The issue is that managing various microservices requires a good bit of choreography.

Story of GNOME Shell Extensions

Filed under
GNOME

A long time ago (exactly 10 years ago) it was decided that the the shell for GNOME would be written in JavaScript. GNOME 3 was still looking for its new face, a lot of UI experimentation was taking place, and JavaScript looked like the best candidate for it. Moreover it was a popular language on the web, so barriers to entry for new contributors would be significantly lowered.

When you have the shell written in JavaScript you can very easily patch it and alter its look and behaviour. And that’s what people started doing. Upstream was not very keen to officially support extensions due to their nature: they’re just hot patching the GNOME Shell code. They have virtually unlimited possibilities in changing look and behaviour, but also in introducing instability.

  • Karl Dubost: Week notes - 2020 w39 - worklog - A new era

    So the Mozilla Webcompat team is entering a new era. Mike Taylor (by the time this will be published) was the manager of the webcompat team at Mozilla since August 2015. He decided to leave. Monday, September 21 was his last day. We had to file an issue about this. The new interim manager is… well… myself. So last week and this week will be a lot about: * have a better understanding of the tasks and meetings that Mike was attending. * trying to readjust schedules and understanding how to get a bit of sleep with a distributed organization which has most of its meeting toward friendly European and American time zones. Basically, all meetings are outside the reasonable working timeframe (8:00 to 17:00 Japan Time). * trying to figure out how to switch from peer to manager with the other persons in the webcompat team. I want to remove any sources of stress.

Programming Leftovers

  • Code your first algorithm in Scratch

    With more kids learning from home this year, it's important to engage them with unique learning opportunities. The classroom looks very different than it did before, and it's going to continue to evolve. So should the lessons we teach. In the first article in this series, I shared how my students taught me to code. Over the next few weeks, I will be exploring how educators and parents can harness the power of coding to teach kids a wide variety of skills. "But I don't know anything about coding!" you may be shouting at your computer. That's one of the beauties of open source code: everyone is a learner, and everyone is a teacher. Whether you're new to coding or you've been doing it all your life, part of the process is making mistakes. It's all about problem-solving and learning how to find information. The greatest tool an educator has in a coding classroom is the phrase, "I don't know; let's find out together!"

  • 5 questions to ask yourself when writing project documentation

    Before getting down to the actual writing part of documenting another one of your open source projects, and even before interviewing the experts, it's a good idea to answer some high-level questions about your new document. [...] Or, what company is behind the document? What brand identity does it want to convey to its audience? The answer to this question will significantly influence your writing style. The company may also have its own style guide or at least a formal mission statement, in which case, you should start there. If the company is just starting out, you may ask the questions above to the document's owner. As the writer, it's important to integrate the voice and persona you create for the company with your own worldview and beliefs. This will make your writing sound more natural and less like company jargon.

  • 33 Excellent Free Books to Learn all about R

    The R language is the de facto standard among statisticians for the development of statistical software, and is widely used for statistical software development and data analysis. R is a modern dialect of S, one of several statistical programming languages designed at Bell Laboratories. R is much more than a programming language. It’s an interactive suite of software facilities for data manipulation, calculation, and graphical display. R offers a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, …) and graphical techniques, and is highly extensible. The ability to download and install R packages is a key factor which makes R an excellent language to learn. What else makes R awesome? Here’s a taster.

  • Find all the prime numbers less than 'n' in O(n) Time complexity

    Our task is to find all the prime numbers that are less than n in Linear Time. We use Sieve of Eratosthenes to find the prime numbers till n. But the time complexity is O(N log (log N)). Here our desired time complexity is O(N). Hence a modified version of the Sieve of Eratosthenes is to be used.

  • PyPy 7.3.2 triple release: python 2.7, 3.6, and 3.7

    The interpreters are based on much the same codebase, thus the multiple release. This is a micro release, all APIs are compatible with the 7.3.0 (Dec 2019) and 7.3.1 (April 2020) releases, but read on to find out what is new. Conda Forge now supports PyPy as a python interpreter. The support is quite complete for linux and macOS. This is the result of a lot of hard work and good will on the part of the Conda Forge team. A big shout out to them for taking this on. Development of PyPy has transitioning to https://foss.heptapod.net/pypy/pypy. This move was covered more extensively in this blog post. We have seen an increase in the number of drive-by contributors who are able to use gitlab + mercurial to create merge requests. The CFFI backend has been updated to version 1.14.2. We recommend using CFFI rather than c-extensions to interact with C, and using cppyy for performant wrapping of C++ code for Python.

  • Foreign Hackers Cripple Texas County’s Email System, Raising Election Security Concerns

    Last week, voters and election administrators who emailed Leanne Jackson, the clerk of rural Hamilton County in central Texas, received bureaucratic-looking replies. “Re: official precinct results,” one subject line read. The text supplied passwords for an attached file.

    But Jackson didn’t send the messages. Instead, they came from Sri Lankan and Congolese email addresses, and they cleverly hid malicious software inside a Microsoft Word attachment. By the time Jackson learned about the forgery, it was too late. Hackers continued to fire off look-alike replies. Jackson’s three-person office, already grappling with the coronavirus pandemic, ground to a near standstill.

    An unnamed U.S. federal agency was hit with a cyber-attack after a [attacker] used valid access credentials, authorities said on Thursday.

    While many details of the hack weren’t revealed, federal authorities did divulge that the [attacker] was able to browse directories, copy at least one file and exfiltrate data, according to the Cybersecurity & Infrastructure Security Agency, known as CISA.

    The [attacker] implanted malware that evaded the agency’s protection system and was able to gain access to the network by using valid access credentials for multiple users’ Microsoft 365 accounts and domain administrator accounts, according to authorities.

New in calibre 5.0

Welcome back, calibre users. It has been a year since calibre 4.0. The two headline features are Highlighting support in the calibre E-book viewer and that calibre has now moved to Python 3. There has been a lot of work on the calibre E-book viewer. It now supports Highlighting. The highlights can be colors, underlines, strikethrough, etc. and have added notes. All highlights can be both stored in EPUB files for easy sharing and centrally in the calibre library for easy browsing. Additionally, the E-book viewer now supports both vertical and right-to-left text. calibre has moved to using Python 3. This is because Python 2 was end-of-lifed this year. This should be completely transparent to calibre users, the only caveat being that some third party calibre plugins have not yet been ported to Python 3 and therefore will not work in calibre 5. For status on the various plugin ports, see here. This effort involved porting half-a-million lines of Python code and tens-of-thousands of lines of extension code to Python 3. This would not have been possible without the help of Eli Schwartz and Flaviu Tamas. Read more Also: 5 Best free software for disk imaging or cloning hard drives
