IE8 on Windows XP does not support SNI

, 64px-Internet_Explorer_7_Logoor “you desktop IT people have broken something”.

Just before Windows XP gets to take a well earned retirement on “the farm”, it popped it’s ugly head up this week with an end user complaining we did something to break their new website

On purpose no less.

It seems IE8/Windows XP was receiving the wrong HTTPS certificate.

Upon investigation, I realised that the issue was that IE8 on WinXP does not support SNI.

Server Name Indication allows a web browser to tell a web host what site it is connecting to.  (A web host can host multiple web sites …).  The reason why a browser needs to tell the web host it connects to, is so the web browser gets the right HTTPS certificate.

If the browser does not support SNI then the browser will get the default web host certificate.  Which may cause certificate errors to be displayed in the browser.

To prove that it was a lack of SNI support causing the issue, I used the excellent Qualys SSL Labs SSL Server Test tool.

I suggested to the customer that they use an alternate web browser, until they can replace Windows XP.

Travelling the “C” Road

HeathcoteIn Victoria, we have several classifications of roads, the “C” classification being the lowest grade of the classified roads.

C’ roads are generally two lane sealed roads with shoulders. ‘C’ roads provide important links between population centres and between these centres and the primary transport network. An example of a ‘C’ road is the Geelong-Portarlington Road (C123).

The good thing about “C” routes is that they really are the road less travelled.  Not much traffic, not many police and you get to see things you otherwise would miss.

Such as riding over a crest on the Burke & Wills Track near Mia Mia, and having a kangaroo bound down the road in front of you.  Skippy was bouncing along at 25 km/h, before he decided to bound into the bush.

The other thing, you get to drop in to shops which have the “Best Shop Award” for the last 5 years running.  The cynic would wonder how so many bakeries/restaurants in the same region, can win so many different prizes?  Made up awards???  Surely not!

My two recent “C” road trips were as follows:
Melbourne –> Echuca (M2 C743 C325 B75 C347 C362 C351)
Melbourne –> Maffra (C101 M1 C426 C486 C103 C105)

(with thanks to Smee for suggesting the Echuca Route)

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.
