I can't access the admin menu

Fri, 08/31/2018 - 20:51

I log in on a Drupal 7 site as administrator user, but I am not able to access the admin menu.

I tried clearing the cache, but it doesn't work. All the user accounts I have tried with have administrator access and have that role.

Does anyone have some ideas on what the problem could be?

Correct field-type to display a book's page

Fri, 08/31/2018 - 20:51

I'd like to create a book in my Drupal site but I chose to do that manually, without using the Book module so I won't be limited by its options.

Thus, I first created a new content-type named "book_pages" and then I gave it a long text field with summary ("body"), and I need a second field-type for paging, but I'm not sure what its field-type should be:

It should automatically include the node order-number** so that if the node is the fifth node of the content-type a user would see the following, when visiting the fifth book_page:

text (body) 5 (page-number)

What field-type should I choose?

Here’s What You Need to Know about Building a “User-Friendly” Website

Fri, 08/31/2018 - 18:36
In the recent years, user-friendliness or usability has become a crucial factor in determining the success of a website. With the competition getting more intense by the minute, your prospects will quickly move on to another site if they don’t find your website easy to use. Your website’s conversion rate can increase by 200% to 400% with a well-designed interface, while you can get a $100 return for every dollar that your company invests in your website’s user experience. That shouldn’t come as a surprise as nearly 95% of users believe positive user experience is the most critical factor they’re …

Employee Spotlight – Keith Thompson, DevOps Training Architect

Fri, 08/31/2018 - 17:46

Our Training Architects worked super hard to create 150+ new enterprise-grade, hands-on training this Summer and the DevOps team released 6 new Courses and 52 interactive Learning Activities.

Meet one of our DevOpsTraining Architects, Keith Thompson, below and see why he loves working at Linux Academy.

Currently listening to: Coder Radio

1. What do you do at Linux Academy?

I’m currently a DevOps Training Architect, but it looks like I’ll be creating development related content in the future. The end of October will mark my first year with Linux Academy.

2. What did you do before this? 

I was a software engineer prior to joining LA. Most of my work was web development, but I also spent a lot of time working on automation and development tools. I was also a “YouTuber” on nights and weekends, which is how LA found me.

3. What do you like most about what you do?

I really just like helping people. When I first switched from studying mathematics to computer science I felt like I had so much to learn. It was true, but I didn’t realize how helpful people in technology can be and I owe a lot of my success to others who were further along in their career providing me guidance and help.

4. What’s your favorite part of working at Linux Academy? 

Interacting with students is my favorite part of my job. I love to teach, but it wouldn’t be near as fulfilling if I didn’t have any interaction with our students.

5. You just released a new course, Basic Chef Fluency Badge, can you tell us about it?

Basic Chef Fluency Badge was my first certification course and it was an update to a course that Anthony James created so I felt a lot of pressure to do a good job. The course and exam cover a broad range of topics within the Chef and the surrounding tools so I have to cover quite a few different things in the course, but I had one main goal for myself: ensure that the student would be comfortable using Chef by the time they finish the course. I knew that if I could meet that goal then the students would have no trouble passing the exam. I’m confident that I achieved what I set out to do with the course and I’m proud of it.

6. How do you live out one of our core 5 missions?

“We put our students’ futures first” is the mission value that I think about the most. Every piece of content that I create is filtered through that idea. If I create something and then later find that it was more of a novel idea and not truly useful to a student bettering themselves then I simply discard it and try again until the benefit is undeniable.

7. What do you like to do in your free time? 

I like to play video games, read, and program. In the 3 months of nice weather we get in the midwest USA I also enjoy golfing.

8. What’s your favorite food?

Tacos. I love all sorts of tacos.

9. What’s your favorite quote and why?

I’m not a big quote guy, but the first that comes to mind is “slow is smooth, smooth is fast.” Everything I’ve ever achieved a decent level of skill in points back to this idea (and a love of practice). If something is worth doing then it’s probably worth doing well, and if you want to do it well then start slow.

10. What’s something you’re really excited about right now?

My wife and I recently moved into our first house, and I’m still pretty excited about that.

11. What do you like to collect?

Books. I love learning and books are a nice way to learn about things other than technology.

12. If you could have any superpower, what would it be, and why?

I’ve thought about this a lot and I’ve got to go with teleportation. Its great for business (ie instant delivery), no more wasted time traveling in the car or plane, safer than a car, and there aren’t any downsides that I can think of.

13. You’re a new addition to the crayon box, what color would you be and why?

Some shade of orange for no other reason than I like orange.

14. Teach us something we may not know in 10 sentences or less.

If you’re playing table tennis, you must toss the ball up at least 6 inches from an open palm before hitting it on the way down so that it hits your side of the table first. In singles, the area of the table that the serve hits on either side doesn’t matter, but in doubles, you need to server cross court from your right-hand side to the opponents’ right-hand side. Outside of organized play, a lot of people seem to get these rules wrong.

15. If you could interview one person (dead or alive), who would it be?

King Solomon. There’s something enticing about being able to ask the “wisest person to ever live” any question.

16. What’s one thing on your bucket list?

I would like to publish a book. It will probably something related to tech or personal finance, but I have no idea when I’ll be able to make time to get to it.

Check out Keith’s new course: Basic Chef Fluency Badge to get prepared to pass the Basic Chef Fluency Badge exam! Through the lessons, hands-on labs, and live environments in this course, you’ll gain the experience necessary to be able to deploy and utilize Chef for configuration management. Learn basic Chef terminology, product offerings, design philosophy and more!

Chef Hands-On Labs in this course:
  1. Setting Up A Chef Server, Workstation, and Bootstrapping a Node
  2. Writing and Deploying a Chef PostgreSQL Cookbook
  3. Configuring Chef Nodes Using Roles

Firefox to Block Tracking by Default, ZeroPhone Project Coming Soon, Google Code-in 2018, OpenStack Releases Version 18 "Rocky" and Greg Kroah-Hartman on Meltdown and Spectre Vulnerabilities

Fri, 08/31/2018 - 17:46

News briefs for August 31, 2018.

Mozilla yesterday announced a different approach to anti-tracking on the internet. Mozilla's new approach means that "in the near future, Firefox will—by default—protect users by blocking tracking while also offering a clear set of controls to give our users more choice over what information they share with sites." In order to accomplish this, Mozilla has three key initiatives: improve page load performance, remove cross-site tracking and mitigate harmful practices.

ZeroPhone, an "open-source Linux-powered $50 smartphone, is being launched on Crowd Supply. The project is coming soon, and according to its description, "It has no carrier locks, bloated apps, or data mining, and it doesn't depend on big companies." In addition, it's based on Raspberry Pi Zero, ESP8266 and Arduino.

Google announces its Google Code-in (GCI) 2018 contest. The contest begins October 23, 2018 and ends December 12, 2018, and "students ages 13–17 from around the world can learn about open source development by working on real open source projects, with mentorship from active developers." See the Google Code-in 2018 site for information for both students and mentoring organizations.

OpenStack released Rocky, version 18, of the open-source cloud infrastructure software yesterday. According to the release statement, the two main new features are "refinements to Ironic (the bare metal provisioning service) and fast forward upgrades". In addition, version 18 addresses "new user requirements for hardware accelerators, high availability configurations, serverless capabilities, and edge and internet of things (IoT) use cases".

Greg Kroah-Hartman warned attendees at the Open Source Summit North America about the "the severe impact the Meltdown and Spectre CPU vulnerabilities could have on them, as well as detailed how Linux kernel developers are dealing with the flaws", eWeek reports. He also strongly criticized the way Intel initially handled the disclosure.

The best defense against deepfake AI might be . . . blinking

Fri, 08/31/2018 - 17:03

Researchers can now detect AI-generated fake video with a 95% success rate–and it’s all thanks to the eyes.

A new form of misinformation is poised to spread through online communities as the 2018 midterm election campaigns heat up. Called “deepfakes” after the pseudonymous online account that popularized the technique–which may have chosen its name because the process uses a technical method called “deep learning”–these fake videos look very realistic.

Tidal-cli-client version 2.0 released

Fri, 08/31/2018 - 16:25

If you are a user of Tidal, like me and use Linux, you propably know, there is no dedicated client for Tidal for Linux. There are some web wrappers, requiring Flash and so on, but how great would it be to have an open-source terminal client for Tidal?

So I have created tidal-cli-client in January. And now the new completly re-designed from scratch version has been released. It supports custom configuration, better error handling, chaching api requests, playback queue control, unit tests and so much more. Check it out on Github: https://github.com/okonek/tidal-cli-client and npm: https://www.npmjs.com/package/tidal-cli-client. I have also written a blog post about this project: https://okonek.github.io/programming/stories/nodejs/open-source/2018/08/29/how-did-i-write-tidalcliclient-20.html

I'd love to get some feedback and new features suggestions from you about my app. Some contributions would be awesome!

Thanks, John

FOSS Project Spotlight: Run Remote Tasks on Linux and Windows with Puppet Bolt

Fri, 08/31/2018 - 16:25
by John S. Tonello

Puppet, the company that makes automation software for managing systems and delivering software, has introduced Puppet Bolt, an open-source, agentless multiplatform tool for running commands, scripts, tasks and orchestrated workflows on remote Linux and Windows systems.

The tool, which is freely available as a Linux package, Ruby gem and macOS or Windows installer, is ideal for sysadmins and others who want to perform a wide range of automation tasks on remote bare-metal servers, VMs or cloud instances without the need for any prerequisites. Puppet Bolt doesn't require any previous Puppet know-how. Nor does it require a Puppet agent or Puppet master. It uses only SSH and WinRM (or can piggyback Puppet transports) to communicate and execute tasks on remote nodes.

Despite its simplicity, Puppet Bolt can execute all your existing scripts written in Bash, PowerShell, Python or any other language, stop and start Linux or Windows services, gather information about packages and system facts, or deploy procedural orchestrated workflows, otherwise known as plans. You can do all this right from your workstation or laptop.

For those already using open-source Puppet or Puppet Enterprise, Puppet Bolt enables you to take advantage of the more than 5,700 modules available in the Puppet Forge for everything from deploying database servers to setting up Docker or Kubernetes. You also can query PuppetDB directly with Puppet Bolt.

Install Puppet Bolt and Run Some Tasks

You also can install Puppet Bolt with apt or yum once you add the Puppet repositories:

$ sudo apt install puppet-bolt

You can install Puppet Bolt on Windows with the available .msi, or if you're running Bash on Windows 10, by using the Linux instructions for the flavor you installed. Follow the link in the Resources section to see detailed installation instructions for your favorite platform.

If you're running Ruby (and have gcc and make on your workstation), you can get Puppet Bolt up and running in moments with the simple command:

$ gem install bolt

In just a few minutes, you're now ready to start running one-off commands, tasks, scripts or plans. Puppet Bolt is perfect for troubleshooting or deploying quick changes, distributing scripts to run across your infrastructure, or automating changes that need to happen in a particular order as part of an application deployment. See the built-in Puppet Bolt commands by running:

$ bolt help

Figure 1. Built-in Puppet Bolt Commands

A typical Puppet Bolt command looks like this:

Bang & Olufsen’s new speaker is pure skeuomorphism

Fri, 08/31/2018 - 16:04

And I love it.

Bang & Olufsen’s new Beosound Edge is either a piece of conceptual art about skeuomorphism, or a gigantic practical joke. I think it may be both.
