Shame they’re a bunch of morons – they told me taking pictures of their restaurant from the street was illegal (!?). If someone came and took a picture of an ad I plastered on my wall…I’d be more happy than anything, it would mean people notice it (even if it was a competitor). Anyway, if you come to Barcelona, check out Fresh&Ready, not for the food, but for the free WiFi.
Browsing through some old photo albums, I came across a set of photos from my years with the Kinder Mountain Rescue Team, based in Hayfield, UK. After going through high school in Southend, near London, I moved to Whaley Bridge, a small town south of Manchester, to pursue my degree in Aeronautical Engineering at the University of Salford. One day, while walking towards the popular Kinder reservoir area for a weekend walk, I noticed a small hut belonging to the KMRT, and basically crashed into one of their meetings. After talking to some people from the exec team, I was accepted as a probie, not without a strange look on some faces (”what’s this guy from Spain who we’ve never seen before doing here?” sort of look). Normal probie period is six months, but, normally probies are introduced by team members, who know them and their capabilities and can make the recommendation. I was coming out of the blue, so I spent about a year as a probie, before being admitted as a full member.
Why, would you ask? Well, a couple of years earlier, I broke an ankle while descending a winter route in the French Pyrenees, and was brought to safety by a mountain rescue team. Ever since, I felt there was something I had to pay back – and this was the chance. During my stay with the KMRT, we performed all sorts of operations, from rescues of people with broken limbs, to searches for lost walkers. We trained a lot, and participated in huge exercises involving many local teams, Police, RAF helicopters and aircraft, K-9 units, and the ambulance service. One of the exercises I keep pictures of is a paper helicopter crash on Kinder plateau (we used the word ‘paper’ to describe anything fictional in the contest of an exercise, for example, “call the paper RAF and request a paper helicopter and a paper ambulance”, just in case anyone listening on the radio thought it was the real thing)
A very realistic victim, with a very realistic amputated limb. The excellent members of the Casualties Union provide the most believable victims you can find, with makeup, real bone fragments (from sheep of course!), and other surprises. Everything you’d need to film a good zombie movie.
Finally, this picture was taken during a winter route in Scotland, the most remarkable fact being that we had perfect weather – which is something to put in your memoirs. As we descended, a single, tiny, white and fluffy cloud passed by, as if saying “yeah, you’re not going to get away -that- easily!”. For the record, Andy was just making fun with the ice pick, he didn’t actually hit anyone!
They are usually forgotten, as they tend to see a lot less action than non-airport bound firefighters, but boy, do they have cool equipment to play with! Airport fire departments have some very tight performance parameters, basically, because when a huge piece of aluminium, titanium, passengers and fuel crashes and ignites on or near a runway, every second counts. That’s the reason this 40-ton baby accelerates from 0 to 80 Km/h (50mph) in around 25 seconds. In proportion to weight, this is faster than a 1997 McLaren F1, which hits 100 Km/h (60mph) in 3.3 seconds!
The Rosenbauer Panther 8×8 MA5 airport and rescue firefighting vehicle. Sporting a 1000 hp engine (yes, that is not a typo), it carries 12.5 tons of water, 1.5 tons of foam liquid, and up to 1 ton of NP powder. Full specs here. Up to three monitors (two mounted at the front, one top) give it a range from 25 meters up to 85 meters, all controlled from the cabin with joysticks and cameras. At 11 bars of pressure, the top monitor can empty the water tank in two minutes. The cabin controls look like something out of Star Wars.
Note the complex MFD control system for the hydraulics – so much for turning a wheel and having water come out a hose, right? While I did part-time work at Southend Airport, I was able to ride and operate a much smaller, much simpler, but equally fun Carmichael truck. Will post a pic when I find it and scan it (film rolls back then, the only thing digital in cameras was your finger).
MS Paint, Visua, Irfan View, Adobe Photo Deluxe and Paint Shop Pro will be mentioned here. This group has been cited because they are often found among the software available to users.
MS Paint is installed with Windows. It can be used for cropping and re-sizing, among others.
Irfan View is a free download. Irfan View is full-featured viewer/modifier/converter.
Visua can be obtained from private archives and is mainly an easy-to-operate viewer and format converter, which can be used to crop and re-size.
Adobe Photo Deluxe is often bundled with purchased peripherals like printer, scanner, or camera. It is a full-featured viewer/modifier/converter. More complete image application programs like Adobe PhotoShop LE have occasionally been sent as free software with the purchase of a peripheral.
JASCs Paint Shop Pro has many uses, and is suitable for colorizing and some types of retouching. It also is an image format converter, with the standard supported file types. It has a collection of tools that allow a user to make many types of midifications to an image. In the Colors|Adjust tool, there are six menu choices that provide dialog screens for making modifications. Among them are a gamma tool adjustment where the gamma values selected for red, green, and blue may be selected independently or together.
Altering the image content (in addition to the modifying steps shown above) can include:
Smoothing edges, reducing granularity, reducing moir patterns, adding special effects, balancing brightness from one region of the image to another, retouching, rotating the image by multiples of 90 degrees, rotating the image by a selected amount, and flipping an image horzontally or vertically.
Printing features may include:
Print preview, an image scaling and positioning feature, rotating the image by 90 degrees, presence or absence of header, footer, pre-set margins, etc.
Viewing features may include:
Manual or automatic stepping through a collection of files, viewing a cluster of files as thumbnails, reproducing sound files along with images.
Applications to add displayability to images include:
Adding captions and/or legends, adding automatic presentation features to an image collection.
Displaying animated images:
Animated GIFs are a stepped sequence of GIF images which simulate motion. Animated GIFs wont work in all viewing software. They are commonly used on web pages, as they will display properly in web browsing viewers.
A brief discussion on images which are produced in scanner formats or in image converter formats.
When working with images in scanner software or in image converter software, it is useful to remember that these are temporary image files with formats which:
Can modify the appearance of the image file that was imported. Can be used to make a print of the modified image. Usually wont be useful in this current format to share but will allow you to see what you have Must be saved or exported to a folder elsewhere on a drive which has a folder assigned to accept it, if you wish to share it or archive it. Dont alter the source image that is, not unless you save or export the file and assign the same file name and place it in the folder from which it came.
Although such scanned temporary files may be retained by some scanner software, they will only serve as your own archived images for later retrieval, and then generally for short retention periods.
Just today UPS dropped off (well, I intercepted the driver in mid-flight, but that’s a different story) the Jawbone Bluetooth headset I was waiting for – and boy, does it work wonders! This has to be the best implemented piece of DSP technology I have seen. If you don’t believe in ‘official’ demos and blurb from jawbone.com (they are true), just check out this audio recording [WAV, 48kHz, 1.7MB]. The first part is recorder using my Mac with an unsquelched radio about 30cm from the headset, with the DSP turned off. I then turn it on, and the audio is recorded perfectly, with barely a hint of the background noise.
How do they do it? I’ve not opened this baby up, as it’s too good-looking (and expensive), but it seems that they combine two directional microphones with a vibration sensor (the small white dot you see on the picture) that picks up bone-transmitted voice from your jaw (thus the name). By matching the vibrations, which are not enough to actually record sound, with the incoming audio from the microphones, they can take away the extra noise very effectively. I should know, as in my previous job, one of our biggest problems was noise and echo cancellation (I was responsible for electronics R&D at SouthWing, designing and testing Bluetooth headsets and other accesories) – and we could never completely kill feedback echo, and noise – forget it. Our designs were in the top league as far as audio quality and noise went, but try what I just did today and the whole recording would have been like the first half.
Good job, Aliph!

Maybe it is time to get creative – today I got mighty pissed off at them, because the driver who was supposed to deliver my Jawbone headset today, was “confused” by an address like this:
Street Name 16 my@emailaddress.com
Apparently, the fact that the contact email got wrongly appended to the street address caused major confusion in the brain cells of this driver, who should of course apply for Mensa right now. The rest of the address was just fine, the only thing ‘weird’ was the email address mixed in. Of course, they cannot turn him around, and I have to wait until tomorrow…
