You get what you pay for…

Sep23
2011
avatar Written by Alex

The old adage the “you get what you pay for” is mostly true. It means you don’t get anything for free, and where you scrimp on the cost you’ll tend to get cheap crap in return.

This is certainly true in the broadband market: if you see a high headline rate for peanuts (think adverts for ‘unlimited’ 24MBps broadband at just £5/mth), then the chances are pretty high that you’ll be throttled to hell and cut off after you’ve managed to download a couple of gigabytes. Similarly if you pay more for a more honest ISP – ‘honest’ in that they don’t massively oversell their backbone network – then you’ll typically see much more reliable (and faster) results.

Now, regardless of all that, we all get screwed by the fact that the performance of xDSL technologies degrades over distance: that 24MBps might be almost true if you sleep under a desk in the exchange; it certainly isn’t true if (like me) you live a good few kilometers away. This problem is the catalyst for no end of inventive measures taken by users, from foil wrapping cables to eliminate noise, to establishing private microwave links to friends with faster connections. Me? I stick with BE who at least allow me to control the all-too-critical SNR ratio myself for a fairly reasonable price.

The SNR ratio determines the balance between all-out-hell-for-leather speed and make-it-actually-usable reliability. At one end of the spectrum you’ll have a line that synchronises at a high speed but is so noisy that packets get garbled along the way; the result is a slower real-world speed because all those garbled packets need to be retransmitted (probably repeatedly) until they come through in one piece. At the other end, you have a line configured for reliability, where potential speed is sacrificed to esnure all packets come through in one attempt. Obviously, the balance lies in the middle: there is always a sweet spot where the optimum SNR lies, and it’s always some way below the ISP’s determined setting (they want to avoid you phoning in and costing them money of course).

Unlike most ISPs, my BE line lets me set that figure. Their fastest setting gave a 20% speed boost over my previous ISP with no (perceptible) reliability issues. Great! I’ve now long believed that this is about the maximum speed my 6km-long line can support.

But, it turns out that, just rarely, you get more than what you pay for. In my case, I have a Billion 7800n router that is pretty awesome. It’s awesome before you know about the hidden /snr.html page. After that you discover it’s friggin’ marvelous! – it’s simply the best router you can buy for xDSL internet access (IMHO) … Why? Because it allows me to set my SNR below even BE’s lower limit, and somehow manages to still pull it off with no (perceptible) reliability issues.

The end result? Another 25% speed increase for free, gratis, nada.

Amazing Amazon

OK. Those who know me well know that I’ll give people (or companies) a hard time when they need a good kick up the arse. Those who know me really well know I’ll also go out of my way to recognize the exceptional.

In Cyprus I dropped my Kindle. It was in its case, and was dropped from only a couple of feet, but I dropped it through clumsiness and the screen cracked. I didn’t buy the nice scotch at the airport on the basis that it cost the same as the replacement Kindle I expected to have to buy.

Cue Amazing Amazon. Yesterday morning at around 8am I clicked the ‘Contact Us’ button on their website and within 10 seconds had a call from them. Having explained my clumsiness and that my Kindle is 11 month’s old and well used/loved/battered, the very helpful guy on the other end explained that they believe a Kindle should survive a 5 foot fall and he’d therefore send me a replacement. That replacement turned up now.

Let’s recap: I have a device that’s barely within its warranty. I’m clumsy. I drop my device. I break my device. There’s no manufacturer fault at all.

And yet Amazon manage not only to take it on the chin on my behalf but get me a replacement device within 26 hours. Oh, and they’ll pick up the other one from anywhere, whenever, at my convenience.

THAT my friends is how to run a business and keep your customers fiercely loyal! Amazon, I’m yours.

Erect, oink moos / Cookies Mentor

I don’t understand why the web is pretty unusable without cookies.

I’ve taken to using the excellent Cookie Monster add-on for Firefox to eliminate the quite astonishingly array of advertising and tracking cookies that I’d picked up. Since then, no tracking cookies, but almost every site breaks at first until it’s explicitly permitted to write a cookie, most without any kind of warning or error message. This was abundantly clear when trying to buy a poster photo print at the weekend.

Cookies and sessions are not the same thing, and apparently the web programmers responsible for much of what’s out there don’t quite get that. Here’s a hint:

Sessions encompass the scope of my current interaction with your site. Not just this single stateless HTTP request, but my whole interaction. Feel free to put a session ID in the URL. This in no way precludes you from handling my entire interaction, whether it’s viewing the front page of your postcard site or actually purchasing something.

Cookies encompass the scope of multiple interactions with your site. That is, they provide a method for you to store a piece of information that enables you to correlate multiple sessions.

The functional difference to both of us is minimal: if I refuse your cookie, I’ll have to identify myself every time I establish a new session. That is a reasonable fallback and is my choice. I appreciate this might interfere with your ability to sell my browsing habits to all and sundry, but (shockingly) your and my idea of the role you play in our relationship is different.

In the end, I bought my photo print from a site that gave me the product I wanted without forcing cookies on me.

To the rest of you, fix it or f**k off.

The balance between ful and less.

Useful: Being able to do one job, procure one’s tools, and generally do what you’re paid to do.

Useless: Being so drowned in bureaucracy that you can’t achieve anything.

I recognize that organizations have a requirement to track and measure; that governance and accountability is important. But I seem to find more and more people these days who suffer from an inability to do the most simple and mundane tasks in their jobs. In their wisdom, their organizations have elected to wrap everything in process and traceability, even when the cost of doing so vastly outweighs the risk of not.

It reminds me of a valuable lesson I learnt many years back at IBM: I needed to do an hour-long task. My programme management (in their wisdom) insisted in wrapping this small task in The Project Management Method, which did little except turn it into an 80 man-day monstrosity where nothing was achieved except many dozen-attendee meetings. Unsurprisingly for anybody who works (or worked) in the corporate world, after four months of meetings, the ‘project’ entered JFDI mode (“Just Fucking Do It” for the uninitiated) and was completed by lunch. We all have stories like this.

What’s this got to do with the present day? Well, that programme’s interest then, and my customers’ interests now, are around risk mitigation. At one extreme, everything’s a free-for-all and nobody knows what the hell is going on. At the other, you can’t go to the toilet without filling forms in triplicate. It turns out there’s only a process for the latter. And the real problem is that nobody seems to have accounted for the fact that the risk mitigation bureaucracy is itself a risk.

I propose a new method; One that establishes a formula to determine the JFDI threshold for a given organization: that is the value/time/cost where the risk of doing something is significantly outweighed by the risk of risk control.

I don’t know what the formula is yet, but I’m sure the risk of wasting my time discovering it will be worth it.

Social networking

Jul24

(Today’s modern) Social networking is largely defined by Facebook and Twitter. However, for me, both’s flaws are based on two incredibly simple statements:

- The Facebook model assumes that you have one, single, social network. At Harvard this was true; for the rest of the world it most certainly isn’t! All of Facebook’s privacy concerns and the endless stream of mindless junk on there boil down to this one fact. And when you can’t filter the single network, that’s when the problems occur.

- Twitter is nothing more than pub-sub text messaging. This is a model that works well only for those whose communication patterns follow the pub-sub model: namely companies who issue public statements of one kind or another; and celebrities. For all other users it is little more than an ineffective email.

So?

Well, I’ve been playing with Google+ and it seems to deal with these problems quite nicely.

Circles enable the definition of multiple social networks, providing both privacy and filtering capabilities – so simple and yet powerful enough to filter the wheat from all that chaff! For Facebook this is an interesting problem: introduce Circles-like functionality (and no, lists are not quite the same) and you risk your business which rests on whoring out information to all and sundry; don’t and you risk your business by losing users in droves.

Google+ doesn’t seem to provide any obvious method for direct communication with a contact. Don’t get me wrong… you can do it, but it’s not obvious. For me, this equates to them not trying to replace email with pseudo-email, which can only be good! (Think of getting Facebook emails telling you to log onto Facebook to get a message – why on earth did your ‘friend’ not just email you in the first place?!).

I left Facebook about 18 months ago because of the mindless pitter-patter of drunken photos, baby photos and generally garbled crap. As far as I can tell from Mrs Me, I haven’t missed anything in that time. But that doesn’t mean I don’t see a use case for social networking – I do. Just not the way Facebook does it.

So, with Google+, am I a social networking convert? Well, only if it meets my use case for social networking which, so far, it seems to. So far, it has none of the chaff due to its invite-only status – though even when it does inevitably arrive I can filter that out. It has built-in video-conferencing, giving it the potential to replace the oh-so-bloated Skype. And it has no ads. In short, it seems to allow me to share things with select groups of people.

Time will tell.

UK terror-ier than who?

Jul11

Reading today on the BBC, they include the scare-mongering definitions of terror threat levels in the UK:

UK terror threat levels

  • Critical – attack expected imminently
  • Severe – attack highly likely
  • Substantial – attack a strong possibility
  • Moderate – attack possible but not likely
  • Low – an attack unlikely

Now, this just reminded me of a time I went to a restaurant and they handed me a feedback/comments card that had the question:

How did you rate the service today? : Good/Very Good/Excellent

Given the very definition of the word ‘moderate’, I assume it should fall in the middle. Surely a more balanced set of definitions would be along the lines of:

  • Critical – expected imminent attack
  • Likely – attack highly likely
  • Moderate – attack possible
  • Unlikely – attack not likely
  • Very Low – never say never, but it really would be a surprise

Or maybe, I’m just not ‘terrorized’ given the fact that I’m more likely to succumb to, well, pretty much anything else (particularly when I drive).

Re-opened

This site has been a blank facade for quite a while now. There’s a reason for that: I tend to communicate with those I wish to via the traditional methods – email and the phone!

But, people get confused, and expect to find things here. So it’s re-opened.

This isn’t to say you’ll find endless witty or erudite posts… you won’t. But there are links above and on the right to some key services that I do provide – namely Webmail and file transfers, and some that I consider truly useful, like the excellent ITA Flight search tool.

Yes, I will post something here occasionally, but it will likely be work-related – thoughts on BPM (that’s the self-referential BPM Pattern Management acronym btw.) perhaps?
