A Closer Look at Damn Small Linux

The take-along operating system

Saving Other Data
Other files that you download or create should be handled with care. You'll want to make sure to save on the permanent storage of your keydrive rather than a transient directory elsewhere. This is where your /myfiles subdirectory comes in handy. Save to this directory and you can count on finding your files again on the next reboot, even if you boot up on a different computer next time.

Taking it Along: Everything-To-Go with MyDSL
Restoring Customization and Saved Applications
Everything you tucked away on your keydrive will be available next time you boot up. This happens in part because DSL makes a backup of some important system files and directories when you shut down. To make sure this happens properly it's a good idea to do a manual back up before you shut down the computer.

To back up, choose the following from the DSL main menu: System | Backup / Restore. Next enter just the device name where you want your backup saved. If you booted from a CD and have a keydrive inserted, use: sda1. If you have a bootable keydrive with a second partition for data use: sda2. Click "Backup" and wait for the program to finish before shutting down. This creates a compressed archive file called "backup.tar.gz" in the root directory of the filesystem.

When you boot up next time, DSL will search for and discover its backup archive on the keydrive and restore the files and settings back to the way you last saw them. Now any computer you boot up with your take-along CD/floppy/keydrive will seem like your very own.

Other Uses for DSL
Internet Kiosk
Let's say you want an inexpensive way to convert some old PCs into a collection of Internet kiosks for an art gallery, business directory, or school project. Running DSL with Firefox would make this easy.

First, you can make Firefox start up automatically at boot time. Just edit the file called ~/.xinitrc and insert this command:

/usr/local/bin/firefox http://your.home.page &

For a kiosk it would be good to disable extraneous menus and applications and limit the scope of the browser. For more information on building Linux-based kiosks, there are a number of how-tos available (Google: "linux kiosk"). Once you've got one kiosk working, it would be easy to duplicate the contents of its keydrive onto others to create more kiosks.

Web Server (System | Control Panel | MonkeyWeb)
For fun I turned my bootable keydrive into a portable library of e-books hosted on a Web server. It runs a MonkeyWeb server - included with DSL - to serve out electronic books that I downloaded for free from Project Gutenberg (www.gutenberg.org). First I copied a number of classic e-texts into the /dsl/Share directory. Then I started up the MonkeyWeb Web server (included with DSL) from the System | Control Panel menu. Now users can access these books from any computer on the network by browsing to http://192.168.1.102/Share. With a few changes this machine can be configured to automatically serve out e-texts from a better-named URL every time it boots.

Remote Desktops
Another handy trick is to make DSL available remotely from another computer. To do this I downloaded VNC (called "vncserver") from MyDSL. VNC is a remote desktop program. Many client programs exist for Windows and Mac. I use the popular "Chicken of the VNC" (Google: "vnc chicken") for OS X to access my "headless" DSL (i.e., no monitor). Once you've installed "vncserver" from MyDSL, select MyDSL | vncserver | vnc4x0 and connect to your DSL machine using its DNS address, e.g. 192.168.1.102. When running full screen, the PowerBook appears to be running DSL.

In summary, I've found this take-along operating system to be a great companion for doing most of what I need from a computer. Once your keydrive is configured the way you want, it will seem like you can take your computer everywhere without really having to take your computer anywhere.

DSL is a good minimalist distro. If you are looking for a more usable distro you should try a lighter PCLinuxOS versionsuch as PCLinuxOS Junior or PCLinuxOS TinyMe.

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
