October 10 2016: Manchester BarCamp and tracking intrusions on uWSGI

As no-one had prepared anything specially for the meeting and David S was occupied trying to get Adobe Flash to work on John W’s computer, we chatted among ourselves with Brian and Ash sharing their experiences of Manchester BarCamp. The arrangements had been better this year with half a dozen lecture rooms available. Brian had given his IoT talk which he had tried out on us the previous month and they had enjoyed sessions on Hacker Packet Radio and Git.

September 12 2016: MQTT, Node-RED, micro-benchmarks and review of the year

Brian gave a demonstration of live messaging between ‘things’ using MQTT in which members were encouraged to participate; this involved installing Mosquitto, a message ‘broker’ for MQTT, and then connecting to the temporary wi-fi network which Brian had set up.

August 8 2016: Intel Compute Stick, Jekyll, Slackbuilds, reveal.js and Instant Messaging

John H announced that David C was moving back to the area after his wife had obtained a job in Leeds.

John showed his Intel Compute Stick; unfortunately, we did not have a female HDMI connector to enable it to be demonstrated.

Darren described the on-going saga of trying to get Slackware 14.2 running with LVM where he had made progress but not found a complete solution.

July 11 2016: Prototyping, VHS to DVD, Huginn, booting to LVM and UPS

John H shared a video he had made of a student presentation on prototyping in 1987; students had been divided into groups of four to research a topic and his group had decided to present their results by way of a series of sketches. At the time development mostly involved COBOL and programming only started after the requirements had been fully specified which normally meant that, by the time the program was delivered, things had moved on and the program no longer met the needs of the organisation. The proposed solution was prototyping of a model of the program to get user feedback before embarking on the programming or building the entire application by prototyping through a series of iterations in much the same way as free and open source software is now developed.

Brian demonstrated in this presentation how he set up a Raspberry Pi 2 as a router essentially by setting up a static IP during configuration and then handing over to a DNS server.

April 11 2016: BASH for Windows, Linus Torvalds and other matters

David S had hoped to be able to demonstrate BASH for Windows though he had found that he had to sign away all his rights to register on the Windows Insider Program and, when he had done that, found that the relevant option had not being installed on his tablet. So all he could do was point to the BASH on Ubuntu on Windows site.

March 14 2016: dBASE II, Scribus and Raspberry Pi 3 vs Odroid C2

John H picked up on a discussion at the previous meeting to give a presentation on dBASE II. He had never upgraded to dBASE III because it was not backwards compatible with dBASE II (other programs of that era like WordStar and Supercalc had maintained backwards compatibility; so it was possible to use them on both CP/M and DOS machines) and because dBASE II had an operator similar to LIKE "%<substring>%" in SQL which had not been implemented in dBASE III. As he had made extensive use of this operator in his programs, an upgrade to dBASE III would have involved an extensive rewrite of all his programs.

February 8 2016: Parquet, Impala, Internet connections, Linuxone and snooping

Alice started us off with Optimising Impala Queries, or a ‘Distributed Lego Community’, a demonstration of the principles behind Parquet, a columnar storage format, and Impala, an analytic database, for the Hadoop ecosystem. Columnar storage formats overcome the burden of reading every row of a table based database such as SQL.
