Quickstart SDR with gqrx, GNU Radio and the RTL-SDR dongle

Software Defined Radio (SDR) provides many opportunities for both experimentation and solving real-world problems. It is not exactly a new technology but it has become significantly more accessible due to the increases in desktop computing power (for performing the DSP functions) and simultaneous reduction in the cost of SDR hardware.

Choosing smartcards, readers and hardware for the Outreachy project

One of the projects proposed for this round of Outreachy is the PGP / PKI Clean Room live image.

Outreachy and GSoC 2017 opportunities in Computer Security, Cryptography, PGP and Python

I've proposed the PGP/PKI Clean Room as a topic in Outreachy this year. The topic will also be promoted as part of GSoC 2017.

If you are interested in helping as either an intern or mentor, please follow the instructions there to make contact.

Outreachy and GSoC 2017 opportunities in Multimedia Real-Time Communication

DVD-based Clean Room for PGP and PKI

There is increasing interest in computer security these days and more and more people are using some form of PKI, whether it is signing Git tags, signing packages for a GNU/Linux distribution or just signing your emails.

How many mobile phone accounts will be hijacked this summer?

Summer vacations have been getting tougher in recent years. Airlines cut into your precious vacation time with their online check-in procedures and a dozen reminder messages, there is growing concern about airport security and Brexit has already put one large travel firm into liquidation leaving holidaymakers in limbo.

Let's Encrypt torpedoes cost and maintenance issues for Free RTC

Many people have now heard of the EFF-backed free certificate authority Let's Encrypt. Not only is it free of charge, it has also introduced a fully automated mechanism for certificate renewals, eliminating a tedious chore that has imposed upon busy sysadmins everywhere for many years.

These two benefits - elimination of cost and elimination of annual maintenance effort - imply that server operators can now deploy certificates for far more services than they would have previously.

Can you help with monitoring packages in Debian and Ubuntu?

Debian (and consequently Ubuntu) contains a range of extraordinarily useful monitoring packages.

I've been maintaining several of them at a basic level but as more of my time is taken up by free Real-Time Communications software, I haven't been able to follow the latest upstream releases for all of the other packages I maintain. The versions we are distributing now still serve their purpose well, but as some people would like newer versions, I don't want to stand in the way.
