7 ways to remember Linux commands

Friday 13th of December 2019 03:00:34 AM

Some Linux commands are very easy to remember. The names may have only a couple letters and they often relate directly to what you want to do – like cd for changing directories or pwd for displaying the present working directory. Others can be very difficult to remember, especially if what you want to do relies on using a series of options.

So, let’s look at some commands and tricks that can help you remember commands that do just what you need them to do and that make issuing those commands so much easier.

Google Cloud gets a new family of cheaper general-purpose compute instances

Friday 13th of December 2019 12:00:28 AM

Google Cloud today announced the launch of its new E2 family of compute instances. These new instances, which are meant for general-purpose workloads, offer a significant cost benefit, with saving of around 31% compared to the current N1 general-purpose instances. The E2 family runs on standard Intel and AMD chips, but as Google notes, they also use a custom CPU scheduler “that dynamically maps virtual CPU and memory to physical CPU and memory to maximize utilization.”

Companies Prefer Hybrid Cloud to Escape Public Cloud Data Grabbity

Thursday 12th of December 2019 07:12:29 PM

As the cloud native space is maturing, customers have started to discern the pros and cons of public cloud. They can see not just the facade of convenience and promised cost savings, but also the bills piling up and having to hand over critical business data to public cloud companies.

Red Hat recently conducted a global customer survey about this and results indicate that customers prefer hybrid cloud over public cloud. More than 31% respondents actually used the term hybrid cloud as their cloud strategy.

Rob Hirschfeld, founder and CEO of RackN and attendee of the recent Gartner IT Infrastructure, Operations & Cloud Strategies Conference, noticed a similar tone. “Discussions and data from the Gartner IO Summit support that hybrid is preferred. There’s just so much existing infrastructure that it’s not practical to be ‘pure’ anything! It’s not so much that they want hybrid but that it’s the reality they are facing.”

There are many reasons why customers prefer hybrid over public cloud or pure private cloud. Red Hat says it boils down to three factors: data security, cost benefits, and data integration.

“Everyone accepts that cloud is secure; however, operators are starting to question how well they can control their data in cloud. Also, some of them don’t trust the cloud vendors, especially with some of the new analytics services,” said Hirschfeld.

Hybrid cloud enables customers to balance all three factors highlighted in the Red Hat survey. They can move pieces of their infrastructure between public and private cloud depending on the need. It lets them reap the benefits of public cloud without having to compromise their data.

Although 31% might seem like a small number, it doesn’t mean that the remaining 69% is running their workloads on public cloud. In fact, only 12% described themselves as having either a public cloud first strategy or a strategy to standardize on a single public cloud. Red Hat says 6% described their strategy as multi-cloud based on multiple public clouds, while 21% have a private cloud first strategy.

In particular, EMEA respondents described themselves as having a private cloud strategy, not hybrid. This region is concerned about handing over their data to US-based cloud companies, given its current political landscape. A simple embargo on your country will cut your entire business out of the public cloud run by Google, AWS, and Azure. Some of the biggest use cases in this region involve companies building their own private and public cloud using OpenStack.

Perhaps the most worrisome finding is that there are still companies without any concrete cloud strategy. Around 17% of the respondents were still working on a plan, while 12% respondents didn’t have any plan at all. Unfortunately, these companies are so far behind the curve that their future hangs in the balance. Hirschfeld warns that there is an urgency to cut their technical debt and embrace cloud now or they will find it hard to survive in the modern world.

In fact, Hirschfeld states that you need to have a cloud strategy even if you don’t use cloud. “The reality is that cloud is the default deployment choice for everything — from demos and proof-of-concept to training — because it’s predictable and accessible.” Teams must adapt to the patterns, even if they are not adopting.

The Red Hat survey found that companies do recognize the importance of building up technical skills. When asked to choose their top non-IT funding priorities, respondents chose both technical skills training (16%) and a digital transformation strategy (16%).

However, new technologies and jargon are emerging at such a fast pace that it’s virtually impossible to find experts (or even skilled professionals) in technologies that were open-sourced at CNCF just a month ago. The hype/adoption curve is so accelerated that it has gotten silly. Therefore, porting to the latest shiny requires evaluation.

“The reality is that new projects, even Kubernetes, still need baking time for scale operations. If there are not enough people with knowledge, then it’s OK (really, it’s required) to pick your battles or slow your adoption,” said Hirschfeld.

Devs: Open Source Is Growing Despite Challenges

Thursday 12th of December 2019 02:00:29 PM

Optimism about the future of open source is high among software developers worldwide. However, a growing number of devs worry that a lack of funding and corporate support threatens its sustainability. That is one of the key takeaways from DigitalOcean’s second annual open source survey, published in its “Currents, Open Source 2019,” seasonal report last week.

The online survey provides a snapshot of the state of open source, as well as a gauge of the inclusivity and friendliness of contributors. More than 5,800 developers from around the world participated. Overall, developers were optimistic about the state of the open source community.

Hello, LineageOS 17.1

We have been working extremely hard since Android 10’s release last August to port our features to this new version of Android. Thanks to massive refactoring done in some parts of AOSP, we had to work harder than anticipated to bring some features forward, and in some cases, introduced implementations similar to some of our features into AOSP (but we’ll get to that later). First, let’s talk about naming versioning - you may be thinking “Shouldn’t this be 17.0, as AOSP is on 10, and not 10.1?”. and given our previous versioning, you’d be correct. When the December Android Security Bulletin (ASB) dropped, we rebased on the more feature filled Google Pixel 4/4 XL tag of AOSP. We decided that, in the future, if we decide for any reason to rebase a large number of repos on a different tag, we will uprev our subversion, eg. 17.0 -> 17.1. As per this migration, on March 4th, we locked all lineage-17.0 branches and abandoned existing 17.0 changes. Not to fear, you can always cherry-pick your changes to 17.1, even via the Gerrit UI if you’d like! Read more Also: LineageOS 17.1 released

Red Hat Enterprise Linux helps pioneering unmanned marine research

In 1620, the Mayflower embarked on an uncertain journey across the Atlantic Ocean, with more than 100 pilgrims on board hoping to begin a new life in the New World. Now, 400 years later, The Mayflower Autonomous Ship (MAS) will follow in the footsteps of the original ship from Plymouth, England to Plymouth, Massachusetts. Only this time, there will be no human captain or onboard crew. It will be one of the first full-sized, fully-autonomous and unmanned vessels to cross the Atlantic Ocean. The MAS project is a global collaboration led by marine research organization Promare. Conceived as a way to commemorate the 400th anniversary of the Mayflower voyage, it could have long-lasting implications for the shipping industry and the future of oceanographic research. The autonomous shipping market is projected to grow from $90BN today to over $130BN by 2030. However; many of today's autonomous ships are just automated and do not dynamically adapt to new situations. Using an integrated set of IBM's AI, cloud, and edge technologies, ProMare is aiming to give the Mayflower the ability to operate independently in some of the most challenging circumstances on the planet.
