BT Midband: Just like ordinary dial-up, only without the good bits (part 2)

My crazy rant about BT’s Midband internet service yesterday wasn’t completely out of the blue. I have spent time with the product. Too much time, in fact. It took me about an hour to wade through BT’s hundreds of customer service and sales numbers to even order Midband. And then I spent three and a half fruitless hours on Saturday trying to get it to work. And failing.

I’m going to be cutting and cruel to BT in the rest of this article, but I do have to give them some credit up front: after spending 20 minutes on hold to their dedicated Midband Technical support help line, the woman I spoke to was top notch. I’ve dealt with a lot of helpdesk operators in my time, but never has first-level support been so clued-up and helpful. Maybe I got lucky, or maybe the Midband people are all like this. Whatever the case, I was very impressed. (The conclusion we eventually came to was that there was too much line noise. An engineer is being dispatched to investigate.)

Anyway, on with the disaster movie.

BT Midband: Just like ordinary dial-up, only without the good bits (part 1)

If you’re unfortunate enough not to live in an area covered by cable or BT’s sporadic ADSL service, you used to be limited to dial-up. But the British government and communication regulators have been very keen to show that Britain is “showing global leadership” with regard to the adoption of broadband. So BT (provider of the UK’s telephone infrastructure) has been urged to speed up their roll-out plans, and to look into alternative technologies to serve hard-to-reach areas (like Scotland).

Hence: Midband. Midband is neither dial-up nor broadband, but a demented hybrid that combines the worst aspects of both, and then discards any vestiges of quality the sickly offspring might have retained. In fact, it’s ISDN. The meeting where the service was green-lighted must have gone something like this:


Senior Executive #1: Guys, we need to bridge the gap between dial-up and broadband. We can’t get broadband out to remote areas quickly enough, and if we don’t show some progress soon, I’ll be in danger of losing my six-figure bonus.

Senior Executive #2: It’s worse than that–some members of the board think they might miss out on a knighthood in the next honours list!

Senior Executive #1: Jesus.

Pause for deep thought and reflection upon the fickle nature of job security.

Junior Executive: Hey, why don’t we part-upgrade all the remote exchanges to something cheaper but slower than real broadband? We could call it, I don’t know, Midband?

Senior Executive #2: Mmm, nice. But we’d have to go back and re-upgrade all of the exchanges later. Future costs against current benefits. I’m not sure if the board would go for it.

Senior Executive #1: I like that Midband name, though.

Senior Executive #2: Catchy.

Going Analogue

Since buying a digital camera in 2000 (an Olympus C3000 Zoom) we haven’t really looked back on analogue photography. Although we had bought a brand new APS camera in 1999, it disappeared into a dusty drawer as soon as we’d tested the digital waters. Earlier this year we even bought a second digital camera, a superslim Casio Exilim EX-S2.

The Olympus is a great all-round camera, and takes superb landscape shots, but it is quite bulky to carry around. The Casio is a snapshot camera. It’s great for people pictures, it’s tiny enough to slip into a pocket without spoiling the line of your trousers, and it turns on almost instantly. It’s rubbish at doing landscape or architecture shots, but that’s okay, because that’s not what we use it for.

A couple of months ago, however, we had a little accident with the Casio. The result was a cracked LCD screen, an £80 repair bill, and about four weeks without the camera.

Normally this wouldn’t be a problem, as we still had the Olympus, but it so happened that in those four weeks, Abi was away on her own for a bookbinding conference, and Alex and I were up in Aberdeen visting my grandmother. Abi ended up taking the Olympus down South with her, and Alex and I brought our quaint old APS device: a Canon Elph 260Z.

Now, when APS (“Advanced Photo System“) first arrived on the scene, I thought it was pretty cool:

  • Instead of a normal roll of 35mm film, APS cameras take a little film cartridge. APS cameras all auto-load these cartridges, so there is no messing about with threading film through a series of rollers.
  • The cartridges are asymmetric, so there is only one way they’ll fit in the camera. There is also a visual status indicator on the cartridge itself to show whether the film is (1) new, (2) in progress, (3) finished, or (4) developed. If your camera allows it, you can even swap cartridges in mid-roll.
  • At the time of taking a photo, you can specify a “framing mode” for the photo. The three modes are “Classic” (4:3 ratio), “HDTV” (9:5), or “panoramic” (about 10:3). The camera will actually photograph as much of the scene as the lens permits, but the framing mode will determine how the picture is cropped when it is printed.
  • When you get your pictures developed, they don’t come back with strips of negatives. Instead, you get back the cartridge itself (with the roll of developed negatives nicely tucked away inside it) and an index print, showing thumbnails of all the pictures on the roll. (And the prints, of course.)

The down side of APS is that it doesn’t have the same picture resolution as 35mm film. The negative is only about half as big, which means (in digital terms) that it has half the pixels. It’s like taking a picture with a 4 Megapixel camera vs a 2 Megapixel camera: you’ll be able to blow up the 4 Megapixel image to a much greater size before the individual pixels become visible. (The “grain” of the film, in analogue terms.)

To be honest, we never took enough pictures with the Canon for this downside to become noticeable. Migrating from 35mm to APS seemed like a step forward.

Moving from digital back to film photography, however, is an enormous pain in the ass:

  • No LCD screen. Some sophisticated film cameras now have LCD panels as well as optical viewfinders, but on digital cameras, LCD screens are the norm. Unless the lighting conditions are really bad (i.e. too much light), I would much rather hold the camera away from my face and watch the LCD, than hold it up to my eye and look through the viewfinder.
  • Every photo you take has to be developed and printed. Getting two rolls of APS film (65 shots) developed at Boots costs £16. If you factor in the cost of the film itself (£3-4 per roll), that works out at about 35 pence per photo. With our digital cameras, it’s not unusual for us to fire off 65 shots in a couple of hours, and that costs us exactly nothing. Note also that APS film and developing is more expensive than 35mm.
  • If you’re used to working with digital, you’ll probably want to get your analogue photos digitised. That means letting the developer stick them on a CD (at additional cost), or scanning them yourself (time and effort). Scanning from the negatives will give you better results, but APS really falls down here because the negatives are hidden inside that formerly convenient cartridge. And they’re not easy to get out.

All this adds up to one result: if you’re used to digital, you won’t ever want to go back to APS. 35mm, despite being the older technology, is actually much more suited to the digital age.

Mailinator follow-up

After I had grasped the concept behind Mailinator, one of the first things that came to mind was, won’t companies start blacklisting mailinator.com email addresses?

Paul Tyma, mailinator’s creator, has answered the question:

“1) Its likely that registration sites will start banning mailinator addresses. The definite first on the list are the ones that already ban yahoo and hotmail addresses and such. The trick is that they already have an infrastructure for banning. If their system has none, its a pain to add and may not be worth the trouble.

2) We have a few aliases set up, but as you can imagine, those just prolong the life. Its possible that enough aliases could become such a chore to track that most registrations will still get through.”

It’s the traditional problem with blacklists. They’re a cat-and-mouse arms race where the “attacker” always has the upper hand, because it always takes the “defender” a finite time to respond. The list of domains that will redirect to mailinator is growing steadily already. If you discover that some site has blocked mailinator.com addresses, don’t worry–there are plenty of alternatives by now.

Turns out that Paul Tyma is also one of the guys behind Dash-O and Dotfuscator, the popular Java and .NET code obfuscation tools. Interesting guy. Have a look at his home page for some recent articles he’s written:

The “Is programming…?” article dovetails with two recent articles by Bob Cringely: “Body Count: Why Moving to India Won’t Really Help IT” and “May the Source Be With You:
IT Productivity Doesn’t Have to Be an Oxymoron, but Outsourcing Isn’t the Way to Achieve It
“. Long-distance outsourcing worries me. It makes me think that there won’t be much of a market for programmers in the UK in ten years’ time, and that I’ll have to do yet another career change. I’ve tried teaching; maybe I’ll become a plumber instead.

His Java article is interesting because I’m start starting to learn Java. He addresses the performance issue, which is something that I’ve always disliked about the language. Server-side Java has never bothered me, but GUI apps have always felt…sluggish. Now I understand some of the reasons behind this.

He does, however, point out the SWT (Standard Widget Toolkit) libraries, which are a set of platform-specific GUI widgets that drive the underlying OS at a much lover-level than Swing does, with a resultant increase in performance. The Eclipse IDE is based on SWT, and it certainly feets nice and snappy. (Unfortunately, SWT seems to be severely under-documented, which is going to make it tough to learn.)

RSS Category feeds

Minor site update: I’ve now created RSS feeds for each entry category on this blog. So, for example, if you’re only interested in my “Techie” posts, you can use an RSS newsreader to subscribe to just that category. You can find the links to each category’s feed by going to the main categories index.

Will this actually be of use to anyone? Dunno. But I had some time on my hands while I was copying some files, and I couldn’t be bothered doing anything more constructive.

Disaster recovery

Sunpig.com was off the air for about nine hours from 2am (GMT) last night. Our site is histed with EZPublishing, whose are either resellers for Colossus.net, or they have their servers co-located at the same facility. Whatever the case, Colossus.net had a fire at their server facility last night. According to their recorded phone message, a power transformer exploded and set the cooling oil on fire.

The fire has been put out now, they have a backup transformer/generator in place, and their servers are starting to come back on-line again. It doesn’t look like we’ve lost any data on the web server, but I’m not sure what has happened to our incoming mail in the time that the server was out. If you’ve sent us anything in the last 12 hours, you might want to re-send it in case it got lost…

Note to self: must finish off those backup scripts…. I’ve got a script that creates a backup of our server database every day, but I haven’t got round to making it do anything useful with the backup afterwards…like email it to me, or FTP it to a different location. Fat lot of good that was going to be if the machine had gone up in flames. Keeping your backups on the same machine as your original files–or even in the same building–is about as useful as the proverbial chocolate teapot.
