Root is often disabled by default when Ubuntu is installed. However, you might find it active when Ubuntu (or other Linux distribution) is deployed in automated environments E.g. when installed with a Virtual Private Server (VPS).
To disable root and administer the system from other user accounts, consider setting up sudo. As root, add a user to sudo that can execute commands as root:
$ sudo adduser trevor sudo
Note that you should replace trevor with a username on your system. Exit the shell as root and login with the username that you just added to sudo (or any other pre-configured sudoer). Use sudo to disable the root password, thus disabling login.
$ sudo passwd -dl root
If you are in a circumstance where you need to enable the root account, type the following while logged in as a sudoer:
$ sudo passwd root
You will be prompted to enter and confirm the password for root.
Read the Ubuntu Official Documentation on RootSudo for additional information and a clear explanation on the benefits of disabling root.
There is a practical session on Thymeleaf and Thymesheet with Agile Staffordshire this month, hosted by Ruth Mills. The session will introduce these Java view layer technologies and how they can be utilised alongside Maven and Spring. This hands-on session will provide an opportunity to use these technologies with examples. It promises to be a good evening and I am looking forward to it.
If you are interested in attending, details can be found on the Agile Staffordshire Blog and on Meet-up. I look forward to seeing you there!
On Thursday 28th May, Paul Williams is hosting a follow-up to his Git at the Command Line session earlier this year. Paul is going to build on the previous session by digging deeper into branchless development, feature switches, and how to commit and push bite size changes with a practical workshop.
As ever, you can read more details about Agile Staffordshire on their blog and register your intention to attend via the meet up group. It is free of charge and new comers are welcome. This month’s Agile Staffordshire event is a practical session, so bring your laptop! Check the meet up notes for software prerequisites. I am looking forward to it.
I wanted to help a friend, Andy Wootton, bring some attention to the Green Party candidate, Claire McInvenna, in South Staffordshire. Take a look at his blog. My local Green Party branch is North Staffordshire.
I’m not stating a political preference, but I do like to help make people aware of discussions. The UK is not a two-party democracy. Use the comments to post Staffordshire party and indepdent web sites. The link spread might help.
Learning how to use a tool is one of the best value-for-time activities for a software developer. Vi isn’t a new tool; on the contrary it has a long and distinguished history as an editor. There’s a real treat planned this evening with Agile Staffordshire and I encourage you to stop by and join in. Details are available on the Agile Staffordshire Blog.
Jason Underhill and Paul Williams have organised a superb showcase of vi being used in a professional context as a tool for software development. These two know their craft and will definitely have some useful and interesting articles to show you.
January’s Agile Staffordshire session looks set to be another great one. It will be great opportunity to acquire some experience with version control software. Git techniques will be presented in this session by the abundantly capable Paul Williams. Stop by on Meet-up and let Agile Staffordshire know that you’re intending to join in!
Network Utility has moved again in the latest release of Mac OS X (Yosemite).
It is located in:
Macintosh HD > System > Library > CoreServices > Applications > Network Utility
Alternatively, you can launch the program from the System Report menu (under ‘Window’). From the Apple Menu, click ‘About This Mac…’. Click ‘System Report…’ and from the ‘Window’ menu, click ‘Network Utility’.
About this Mac… shows system information about your device.
Once the Network Utility is running, use the context menu from the dock icon to show the location of the application in Finder or pin it permanently.
The Network Utility – a useful program that keeps moving location.
Network Utility shown in Finder.
Why does it move?
I would like to know why this application keeps moving. For the longest time, Network Utility was located under ‘utilities’ in ‘Applications’. That made sense. Can anyone enlighten me as to why the location of this useful application is continually obfuscated?
On Tuesday 4th November 2014 at 18:00, the North Staffordshire Branch of BCS and Agile Staffordshire are getting together for a special event. We will be sharing experiences in a series of lightning talks and exercises. This will be a great opportunity to network and learn more about what is going on in the area. This event is also ideal for students with an interest in software development who want to know more about practicing agile techniques in the industry. Continue reading
This month’s Agile Staffordshire session is going to a be a real treat. Ian Russell is scheduled to deliver a session on F#, a functional-first programming language. This is of particular interest to me as I have no experience with functional-first programming and this session should prove to be a good opportunity to ‘dip my toe in the water’.
You don’t need to be a ‘member’ to take part. The Agile Staffordshire sessions are open. Just register your interest on the Meet-up page and read the blog for information.
A reminder that Agile Staffordshire is meeting up tomorrow at Staffordshire University for the Lean Code Challenge. As usual, details are available on the Agile Staffordshire Blog and you can register your attendance on Meetup.com.
I will be there and I hope to see you there too! New members are always welcome, it is a good opportunity to network with industry and academia.
