4 is the number of Melbourne Bike Share Bicycles I needed to get home last night.

Melbourne Bike Share and friends Bicycle 1: Federation Square
Bicycle had a buckled rear wheel, which I didn’t notice until I was powering along in third gear.

Bicycle 2: Coventry Street
Misaligned handle bars, so I was steering on an angle.

Bicycle 3: Melbourne Sports and Aquatic Centre
Bike would “”skip”” a gear.  Not a big problem unless you’re powering along in 3rd gear and it skips on you.

Bicycle 4: Melbourne Sports and Aquatic Centre
This one got me all the way home.

Aside from last nights problems, I’ve had a fairly good run with Melbourne Bike Share bicycles.  By my estimate and experiences so far, I reckon about 1 in 5 bicycles are faulty.

Blind faith in technology

Technology is a great thing.  You’re flying along with not a care in the world.

Then your Electronic Flight Bag fails, leaving you without a clue as to where you are.

Do you, as a pilot, have a backup?

A Civil Aviation Safety Engineer estimated earlier this year that 90% of Visual Flight Rules pilots failed to have a backup.  A backup being maps/charts/lists of radio frequencies.  The requirements to carry a set of accessible set of maps etc. before the flight commences, is outlined in CASA Regulation 233(1)(h)

233  Responsibility of pilot in command before flight
(1)  The pilot in command of an aircraft must not commence a flight if he or she has not received evidence, and taken such action as is necessary to ensure, that:

(h)  the latest editions of the aeronautical maps, charts and other aeronautical information and instructions, published in AIP or by a person approved in writing, that are applicable:
(i)  to the route to be flown; and
(ii)  to any alternative route that may be flown on that flight;
are carried in the aircraft and are readily accessible to the flight crew.

Yes, the Pilot In Command could argue that their EFB worked before taking off, but wouldn’t it be better to have a “Plan B”?

And know how to use it.

10 most annoying road habits

Melbourne Traffic Congestion

In May 2014, the RACV/Leader Newspaper published the results of their “Redspot” membership survey into the worst traffic congestion areas in Melbourne.  Here they are:

  1. Murrumbeena Rd/Neerim Rd, Murrumbeena
    Melbourne’s busiest and worst railway crossing,
  2. Chandler Highway, between Heidelberg Rd Alphington to Princess St Kew
    Bottleneck
  3. Point Cook Rd via Princes Fwy to Dunnings Rd, Seabrook.
    Congestion
  4. Koornang Rd/Morton Ave, Carnegie
    Busy railway crossing
  5. Burke Rd between Monash Fwy and Malvern Rd, Glen Iris
    Congestion
  6. Forsyth Rd/Old Geelong Rd, Hoppers Crossing
    Congestion at T intersection.
  7. Clayton Rd/Carinish Rd, Clayton
    Another busy railway crossing.
  8. High St/Spring St/Cheddar Rd. Reservoir
    Complex railway crossing.
  9. Lower Heidelberg Rd/Banksia St/Burgundy St/Jika St, Heidelberg
    Congestion
  10. Gap Rd/Horne St, Sunbury
    Busy roundabout

They are already suffering a greater punishment than any of us could administer with judgement.

rbftag.jpgIt’s the distractions which harm or kill us.  Consider the following:

The link between all these, is the distractions which occurred.

A study published in June 2002 titled “The Stressed Hippocampus, Synaptic Plasticity and Lost Memories” concludes in part

“Stress, a naturalistic factor that contributes to memory impairments, constitutes a significant problem in today’s increasingly populous and long-living society.”

Or to put it another way:

‘The important factors that keep showing up involve a combination of stress, emotion, lack of sleep and change in routine, where the basal ganglia is trying to do what it’s supposed to do, and the conscious mind is too weakened to resist. What happens is that the memory circuits in a vulnerable hippocampus literally get overwritten, like with a computer program. Unless the memory circuit is rebooted—such as if the child cries, or, you know, if the wife mentions the child in the back—it can entirely disappear.’
– Professor David Diamond in a March 2009 Washington Post article

What lessons can be learnt?

  1. Remember that making a mistaking or error can happen to anyone, including you.
  2. Tiredness is your enemy.  If you are tired, you are more likely to make a mistake.
  3. Be aware of distractions.  Eliminate distractions as much as possible.
  4. Use memory aides, or checklists, as needed.

Enable TLS 1.2 on Windows 7 & 8.

My beautiful picture We’re in the process of developing a new Windows 8.1 SOE for a customer.  One of the things I looked at was Internet Explorer HTTPS transmission security.  Out of that, one of the things I recommend is enabling TLS 1.2.

TLS 1.2 – Configure Internet Explorer to use TLS 1.2 by default.
Transport Layer Security is how web browsers* communicate over the Internet.  The current version, TLS 1.2 has a number of security enhancements & protection mechanisms over previous versions.  Enabling it is, not only a Microsoft recommendation, but a good thing.  Internet Explorer will fail back to older TLS versions if the web site doesn’t support TLS 1.2.

You can enable TLS 1.2 support via Group Policy or directly via Internet Explorer –> Internet Options –> Advanced –> Security.

How do I test that Internet Explorer is using TLS 1.2?
Visit:

  1. https://cc.dcsec.uni-hannover.de/
    If the webpage reports under the “Further Information” heading that “This connection uses TLSv1.2 with …”, then you have enabled TLS 1.2.
    or
  2. How’s My SSL?  If, under the Version heading, it says TLS 1.2, then you’re using TLS 1.2.

What about other web browsers?
No.  You’ll need to configure each web browser to support TLS 1.2.  Some have better TLS support than others.

How do I tell whether a website supports TLS 1.2?
Use SSL Configuration Checker to test the website.

What if my web host tells me to disable TLS 1.1 or TLS 1.2?
”Run!”, would be my first thought.  Your web host is telling you that they are not interested in providing a secure website.
