Rasberry Pi

For this weeks ‘from around the web’ we are looking at some very cool screens that I’ve just started working with for an Arduino project, some advice from the National Cyber Security Centre and a brilliant set of resources to build a plan to secure an IT environment.

Nextion displays for Raspberry Pi/Arduino
For a little while now I’ve been working on various little Arduino based projects (of note soil and general environment sensors); in looking to branch out to some more areas I’ve decided to build a ‘sensor array’ for my car and naturally will need some way to display all the data being captured. For this I came across the Nextion displays which come in a variety of sizes, have an easy to use application to design how the screen looks/works and only needs power + serial connectivity to work.

Hopefully pretty soon I’ll get some more detailed examples of this ‘sensor array’ on here.

For a basic but handy document about how cyber criminals breach passwords and for advice on how to make better passwords look no further than this link from the National Cyber Security Centre.

CIS Cyber Security Best Practices
Sometimes organisations are just bombarded with advice on ‘where to start’ with Cyber Security, some might say start with logging, others perhaps just having an inventory of what you have or maybe having the very best firewall you can afford (pro tip it’s the second one!). To get some real answers that are sized appropriately for any organisation the Centre for Internet Security is the place to start.

Having recently jumped into the world of Windows 10 IoT the first stumbling point seems to be Installing an app (which has multiple dependencies) onto my Rasberry Pi 2 Model B using the AppX Manager.

In particular after selecting the AppX file, the Certificate and listing out the Dependencies I get the error:

Commit deployment

Error source: <appx file>.appx

Error code: 0x80004005

The solution quite luckily is rather simple in that you should install the Dependencies using the AppX part of the Install app section first and then just install the .appx file and the certificate. See the screen shots below for more details…
