OERu makes a college education affordable

Friday 17th of August 2018 07:02:00 AM

Open, higher education courses are a boon to adults who don’t have the time, money, or confidence to enroll in traditional college courses but want to further their education for work or personal satisfaction. OERu is a great option for these learners. It allows people to take courses assembled by accredited colleges and universities for free, using open textbooks, and pay for assessment only when (and if) they want to apply for formal academic credit.

Mixing software development roles produces great results

Friday 17th of August 2018 07:01:00 AM

Most open source communities don’t have a lot of formal roles. There are certainly people who help with sysadmin tasks, testing, writing documentation, and translating or developing code. But people in open source communities typically move among different roles, often fulfilling several at once.

In contrast, team members at most traditional companies have defined roles, working on documentation, support, QA, and in other areas.

What is your favorite Linux window manager?

Thursday 16th of August 2018 07:00:00 AM

While many Linux users have a strong preference for a window manager of choice, for those just making their way over from Windows or Mac, it may be hard to understand what a window manager is, or that it's even something you have a choice in. A window manager is the part of your system that dictates how individual application windows look, and how you can interact with, control, and arrange them.

How to navigate your GNOME Linux desktop with only a keyboard

Wednesday 15th of August 2018 07:00:00 AM

Almost ever since I first started using Linux, I've been on a mission to find the perfect window manager.

My first experience with Linux was in the late 90s, and I first tried installing it on my own in the early 2000s. Like many converts, my previous experience was largely with Windows, and so my early mission was to find an experience that closely replicated Windows, or at least let me interact with it in a familiar way.

Automating backups on a Raspberry Pi NAS

Tuesday 14th of August 2018 07:03:00 AM

In the first part of this three-part series using a Raspberry Pi for network-attached storage (NAS), we covered the fundamentals of the NAS setup, attached two 1TB hard drives (one for data and one for backups), and mounted the data drive on a remote device via the network filesystem (NFS). In part two, we will look at automating backups. Automated backups allow you to continually secure your data and recover from a hardware defect or accidental file removal.

HTTP request routing and validation with gorilla/mux

Tuesday 14th of August 2018 07:02:00 AM

The Go networking library includes the http.ServeMux structure type, which supports HTTP request multiplexing (routing): A web server routes an HTTP request for a hosted resource, with a URI such as /sales4today, to a code handler; the handler performs the appropriate logic before sending an HTTP response, typically an HTML page. Here’s a sketch of the architecture:

5 open source strategy and simulation games for Linux

Tuesday 14th of August 2018 07:01:00 AM

Gaming has traditionally been one of Linux's weak points. That has changed somewhat in recent years thanks to Steam, GOG, and other efforts to bring commercial games to multiple operating systems, but those games are often not open source. Sure, the games can be played on an open source operating system, but that is not good enough for an open source purist.

  • Uber Open Sources Its Large Scale Metrics Platform M3
    Uber's engineering team released its metrics platform M3, which it has been using internally for some years, as open source. The platform was built to replace its Graphite based system, and provides cluster management, aggregation, collection, storage management, a distributed time series database (TSDB) and a query engine with its own query language M3QL. [...] M3's query engine provides a single global view of all metrics without cross region replication. Metrics are written to local regional M3DB instances and replication is local to a region. Queries go to both the regional local instances as well as to coordinators in remote regions where metrics are stored. The results are aggregated locally, and future work is planned wherein  any query aggregation would happen at the remote coordinators.
  • SD Times Open-Source Project of the Week: Dev.to
    This week’s highlighted project comes courtesy of a community of developers who hope that their codebase will be used to foster communities like theirs, focused on education and collaboration among peers of any skill level. Dev.to’s codebase is open-source as of last week week and the community-building platform’s developers think that further community involvement in development will lead to great things. [...] Halpern made sure to clarify in the post that this release is not simply a library for creating the types of community-driven communication platforms that dev.to embodies, but the for-profit company’s entire codebase. “However, that is a perfectly valid use case in the future,” Halpern wrote in a post leading up to the release. “If you are interested in contributing such that we can eventually help people stand up their own version of this platform for their own business or society, we’ll definitely welcome that input.” The platform is a Ruby on Rails app with a Preact front-end. The company is hard at work on native apps for iOS and Android but say its technology choices are fluid.
  • RLS 1.0 release candidate
    The current version of the Rust Language Server (RLS), 0.130.5, is the first 1.0 release candidate. It is available on nightly and beta channels, and from the 3rd September will be available with stable Rust. 1.0 for the RLS is a somewhat arbitrary milestone. We think the RLS can handle most small and medium size projects (notable, it doesn't work with Rust itself, but that is large and has a very complex build system), and we think it is release quality. However there are certainly limitations and many planned improvements. It would be really useful if you could help us test the release candidate! Please report any crashes, or projects where the RLS gives no information or any bugs where it gives incorrect information.
  • Mozilla brings back Stylish Add-on to Firefox after it was Banned Last Year
    The Stylish add-on, with which you can give websites their very own style, is back for Firefox. This improvement has been welcomed by many users. The history of this Add-on is quite complicated as it was supposedly twice removed and added back before it was removed again. Now it has been added back as reported by Vess (@VessOnSecurity). [...] The add-on Stylish has been brought back in the Mozilla’s add-on storehouse. What users should know: This expansion was criticized some time prior as a user data collector and has been prohibited and banned a year back from Mozilla’s Add-on store. Owing to its notoriety of collecting data of users’ website visits in a way which makes it convenient to reveal users’ identity to third parties, Google and Mozilla banned it last year. It is indeed surprising as to why Mozilla decided to bring it back to its browser after it was criticized for compromising users’ identity.

  • As Academic Publishers Fight And Subvert Open Access, Preprints Offer An Alternative Approach For Sharing Knowledge Widely
    That's certainly true, but is easy to remedy. Academics who plan to publish a preprint could offer a copy of the paper to the group of trusted journalists under embargo -- just as they would with traditional papers. One sentence describing why it would be worth reading is all that is required by way of introduction. To the extent that the system works for today's published papers, it will also work for preprints. Some authors may publish without giving journalists time to check with other experts, but that's also true for current papers. Similarly, some journalists may hanker after full press releases that spoon-feed them the results, but if they can't be bothered working it out for themselves, or contacting the researchers and asking for an explanation, they probably wouldn't write a very good article anyway. The other concern relates to the quality of preprints. One of the key differences between a preprint and a paper published in a journal is that the latter usually goes through the process of "peer review", whereby fellow academics read and critique it. But it is widely agreed that the peer review process has serious flaws, as many have pointed out for years -- and as Sheldon himself admits. Indeed, as defenders note, preprints allow far more scrutiny to be applied than with traditional peer review, because they are open for all to read and spot mistakes. There are some new and interesting projects to formalize this kind of open review. Sheldon rightly has particular concerns about papers on public health matters, where lives might be put at risk by erroneous or misleading results. But major preprint sites like bioRxiv (for biology) and the upcoming medRxiv (for medicine and health sciences) are already trying to reduce that problem by actively screening preprints before they are posted.
  • MUMPS Masochism part I: Line and Block Scope

    It's sort of an open secret that I sometimes use ANSI M, better known as MUMPS. It was developed in the 60's, and it definitely still looks like something from the 60's. But it's 1,000 times uglier than anything from that decade. I've made plenty of people, from software testers at work to other developers on IRC, recoil in horror from showing them samples of even relatively mundane code like a simple "Hello, World!".

Microsoft Openwashing

  • Microsoft open sources new framework for Windows driver development [Ed: openwashing Microsoft Windows by pretending that when you write proprietary drivers for a proprietary O/S that does DRM, spies on users etc. you actually do something "open"]
  • Microsoft to Open Source Its Network Replication Software [Ed: Microsoft is openwashing some more of its entirely proprietary 'offerings', a hallmark of a company of liars. Come to us! The traps are free, the cages will be "open".]
  • GitHub goes off the Rails as Microsoft closes in [Ed: Microsoft will take GitHub off the rail like it did Skype and LinkedIn (totally lost)]
    GitHub's platform group is about 155 people at the moment and growing, said Lambert. And much of the group's focus is on breaking GitHub apart. GitHub is about a third of the way through an architectural change that began last year. The company is moving away from Ruby on Rails toward a more heterogeneous, composable infrastructure. Ruby still has a place at GitHub – Lambert referred to the company as a Ruby shop, but he said there's more Go, Java and even some Haskell being deployed for services. The goal, he explained, is to make GitHub's internal capabilities accessible to integrators and partners. "Our monolith is starting to break up and we're starting to abstract things into services," said Lambert. "The platform we've chosen to put them on is Kubernetes."

Benchmarks Of Btrfs RAID On Four Samsung 970 EVO NVMe SSDs

With the MSI MEG X399 CREATION that we received as part of the launch package for the Threadripper 2950X and Threadripper 2990WX it includes the XPANDER-AERO that provides 4-way M.2 NVMe SSD slots on a PCI Express x16 card. The XPANDER-AERO is actively cooled and could be passed off as a small form factor graphics card upon a very cursory examination. With this card I've been running tests on four Samsung 970 EVO NVMe SSDs in RAID to offer stellar Linux I/O performance. Here are some initial benchmarks using Btrfs. Read more
