About MISRA C

MISRA C was first published in 1998. Now in its third edition, MISRA C "Guidelines for the use of the C language in critical systems" was established to provide a "restricted subset of a standardized structured language" as required in the 1994 MISRA Guidelines, for automotive systems being developed to meet the requirements of Safety Integrity Level (SIL) 2 and above.

Subsequently, it has been adopted and used across a wide variety of industries and applications including the rail, aerospace, military and medical sectors.

VDA Automotive SYS Conference 2015 Report

Download My Conference Presentation As previously mentioned, last week I attended the VDA Automotive SYS Conference in Potsdam.

The theme of my presentation was MISRA C – Safety v Security and discussed the coverage of MISRA C against ISO/IEC 17691 (the C Secure standard).

As my debut on the conference circuit, I think things went as well as expected, and I'm greatful for the positive feedback received from delegates.

Geocacheing in Germany

Background

The scene is set: attending a conference in Germany, and you have a couple of hours free in the evening. Do you (a) sit in the bar and drink beer, or (b) go geocaching?

A bit of a silly question, really…

A Souvenir From Brandenburg

Souvenir from Stadt Brandenburg

Souvenir from Stadt Brandenburg

Checking the Geocaching website, a circuit of a dozen or so caches looked do-able – with a possible bonus of a six-haul Tracker-hotel. So armed with my phone running the cgeo app, and a translation of the various cache webpages, I set off with a conference co-attendee (aka TheDoctor12)

The Geocaching system offers a souvenir for each Stadt in Germany – so completion of the first cache resulted in the award of a new icon… my first non-UK territory

The Coin and Tracker Bug Hotel

Coin & TB Hotel "Waldlehrpfad" Wildpark Potsdam

Coin & TB Hotel “Waldlehrpfad” Wildpark Potsdam

With three of the first four on the route safely logged, we entered the Waldlehrpfad in such of the Coin and Tracker-Bug Hotel… reportedly holding six trackables.

Unfortunately, only two were present:

  • Grisu der kleine Drache
  • Stefricks Metropolis Express

I retrieved these two for a journey to England… and the other four logged as missing.

Continuing the Walk

Onward we trekked, taking in a further three more but skipping other two planned caches due to too much activity, before reaching the nearest one to the hotel. Unfortunately, in the fading light this wooded area precluded further exploration, so we decided to call it a night. But I went to find Am Boden the following morning!

  1. Haus33
  2. Haveldurchblick
  3. Haveldurchblick 2
  4. Coin & TB Hotel "Waldlehrpfad" Wildpark Potsdam
  5. Einer am Rande
  6. So geht es auch
  7. Blick nach Potsdam #1
  8. Am Boden

I did not "DNF" the three that we did not find, as we skipped them, rather than didn't find them.

An enjoyable walk, in some lovely countryside… hopefully I will be back again some time, to find a few more!

ISO/IEC/IEEE 29119 Faces Objections

As a member of the UK Mirror Panel to WG26, which is responsible for the ISO 29119 standard, I am disappointed to read of the objection to the standard led by the International Society for Software Testing, which has resulted in a formal petition to ISO.

Is Software just a Black Art?

Background

In the August 2014 edition of the IET's E&T Magazine, Tim Fellows wrote an article titled How to avoid getting sucked into the black hole of software development (link).  The article seems to blame the bulk of software related problems on the contracts, but I think Mr Fellows misses the point completely.

I'd like to challenge some of the points made…

A trip down memory lane

Between Easter 1978 and the summer of 1979, we lived at RAF Locking in Somerset.  Since we left, following my father's posting, I have never been back.

Yesterday (20th May) I attended the Reliable Software Developer's conference in Bristol, and (as reported on my Amateur Radio page) used the spare time between sessions to activate a few local Worked All Britain squares. A quick glance at the map had shown that a drive-by was possible…

RAF LockingLocking - The Water Tower

RAF Locking closed in 1999, following the relocation of No.1 Radio School to RAF Cosford.  The site was sold by the MoD in 2002.

Approaching the camp, the water tower was still prominent, and as a glanced at the tower, the car immediately in front of me turned directly into the married quarters at Mendip Road – this threw me slightly, as when we lived there, this entrance was gated and permanently closed. Of course, nowadays, the married quarters are in private hands, so there is no need for the gate to be closed… so I followed…

It was like entering a time-warp… even after 35 years, everything was exactly as I remembered it…

Flowerdown Road

Following Mendip Road, passing the Water Tower, I turned into Broadway, then into Flowerdown Road.

Flowerdown Road - FrontFlowerdown Road - SideJust to repeat what I said above: it was like entering a time-warp… even after 35 years, everything was exactly as I remembered it… although the garage clearly had a new roof, even the garage door was still the same blue that I remember!

I stopped briefly to take some photos, without wanting to draw too much attention to myself.
