Feedback Schmeedback

"Bad Customer -- BEWARE" sign, stamped on forehead

Oops! I spoke out!

Assertion: Online auction site feedback systems do not (in general) reflect the way things work in the real world and are therefore flawed — and unfair.

Supporting (all too common) scenario

You buy a misrepresented product from an online auction site. Specifically, the sales text claims the product is fully compatible with all XYZ’s.

The product arrives, is well made, of evident high quality and in good condition. But it immediately becomes clear that it, in fact, cannot possibly be used with your XYZ. Let’s say that it’s a large, circular object and your XYZ is a fine representation of the proverbial small, square hole. Clearly, the seller has made a mistake. (Or have they?)

You notify the seller of the problem by private email, politely, who responds by denying your (absolutely undeniably obvious and accurate) claim, saying that it’s your fault for, “not knowing how to use the product”. They offer no advice as to how to use it, however — presumably because by this point, they must know that it is indeed impossible. But who knows. Maybe they’re just a bit slow?

So, you try once more to convince them, supplying associated evidence, carefully explaining the (obvious) details as to why the circle won’t fit in the square hole, as it were.

Alas, once more, the seller just (sort of politely) blames you for not knowing how to use the product correctly. “I can assure you that this gadget does fit in an XYZ’s square hole. We’ve sold hundreds of them and never had a complaint before.” This time, they offer to be a nice seller by refunding your purchase money — conveniently forgetting that you would have to pay the shipping cost for return, not to mention all the hassle involved.

(You decide not to bother, because you’ve already paid $5 shipping for the $14 item and value your time and money too much to be stupid about it. Instead, you opt to resell the otherwise fine gadget on the same auction site, this time clearly stating its true nature.)

Having given up on the seller’s ability to be reasonable (or sufficiently intelligent to understand the difference between two shapes?) you try to warn others by posting negative feedback stating, “The seller made inaccurate claims as to the product’s compatibility. It is not compatible with XYZ as they claim. The seller refused to acknowledge this fact (twice) and instead blamed the buyer for ‘not knowing how to use’ the product correctly.”

Missing the point entirely — that they are essentially lying to all who stumble upon their listing for this product in the future — the seller responds by giving you negative feedback, “Buyer not happy with product. Offered a refund. Buyer refused. This buyer is trouble. Do not trade!”

So then, you got yourself burned by a seller and tried to warn others. For your troubles, you got burned again — indelibly. Your once perfect trading record with this auction site is no more, because you simply dared to speak out to warn others about this rogue seller. The auction site’s staff were no help. All they could offer was to mediate the disagreement via email. But neither the seller or the buyer are going to budge.

Conclusion? Online auction site feedback systems are clearly flawed. If  the above scenario were to be played out in the real world, then you might now be required to walk around with a warning sign on your forehead saying, “Bad customer! BEWARE!” — and all at the sole discretion of the seller.

Your only other option would be to do what most intelligent auction site users seem to resolve to do, which is to let the, ‘big bad seller’ get away with wasting people’s time, money and effort through blatant misrepresentation of merchandise, all for the sake of maintaining a nice, pretty, 100% positive feedback. After all, every one knows that placing negative feedback against a seller will almost certainly result in reflected negative feedback, regardless of the facts and there’s nothing you can do about it.

Label me a martyr if you will, but I decided to stand on principal and wear the sign on my forehead.

I am now forever labelled, a “Bad Customer!” Shame on me! Long live truth! (And justice?)

 

Facebook Support an Expensive Sham

Facebook is at it again …

Facebook has long been known for not taking sufficient care with users’ money and privacy, having hit the news headlines on several occasions. Seems they’re at it again.

Yesterday, I *tried* to get a simple ad running on their system, just a test really — though I did attempt to complete payment for a real ad. I tried three times, each time receiving various, different error messages and automated apologies, with messages like “we’re working to fix this problem …”, etc. At no time did I receive any message saying that my credit card had been charged and at no time did I see anything to suggest that the ads had in fact been accepted and lodged for running.

Today, I see that Facebook managed to fix the problem (I’m assuming), gather up the broken database data from my broken orders and then go ahead and charge me for essentially the same ad, run at the same time, to the same audience (all the same settings), three times. It’s not really the exact same ad, since I tried three times to get the ad to be accepted, each time having to re-enter all the data from scratch and each time receiving errors messages. So, technically, the ad was re-created three separate times.

Now, with any decent and reputable online vendor, you’d be able to contact them to query or complain about what had happened and get something down about it … maybe a refund or some credits or something. But not Facebook.

With Facebook, when you reply to a billing email, you simply get a message back saying that they don’t accept email responses to billing notices. They provide a link to a ad-related help page. Of course, every last character of text on that page is about assuming YOU, the user, have done something wrong or don’t know what you are doing.

There is no way to raise a specific request for help, only the FAQ. There is a message that reads…

Please note that if you choose to contact the Facebook Ads team, we’re only able to provide support for inquiries in Dutch, English, French, German, Italian, Spanish, Swedish, Arabic, and Turkish.

… but there’s no way to contact them, that I can find. They further state …

We’re also unable to offer phone support at this time, but will be happy to respond to questions submitted through contact forms on this site.

… but again, there are not, in fact, any “Contact Us” links anywhere “on this site”.

None of this is in compliance with laws designed protect online consumers and credit card users of course. It’s just Facebook, being their usual half-ass selves, making a mess of things.

What’s the one big lesson Facebook keeps kicking back in users’ faces, concerning both privacy and monetary transactions?

IF IN DOUBT — DON’T!

I suppose its only fair that I also point out that the ads did actually run and did in fact gain some 81 clicks at about $1.23 each. So not all was lost, though the cost was 3x the intended budget.

But sorry, Facebook. Your credibility just went down yet another notch. Very, very poor.

2.4GHz Video BAD for FPV RC Aircraft

All the best RC remote control stuff is in the 2.4GHz band now. That makes 2.4GHz video senders a no-no for on board your aircraft. Unfortunately, 900MHz is out too, because it essentially cannot be used legally in most countries at practical power levels without at least a Ham license, and even then nothing appears available that even transmits in the licensed Ham bands. And even if that were overcome, 900MHz is still far to close to 2.4GHz and will still overload the RC receiver circuitry anyway. (Video senders have relatively high output power and MUCH higher power density than RC signals.)

You might think, “Fine, I’ll just use an old 72MHz or 40MHz ‘long antenna’ RC remote controller. Fine. But … you’re going to potentially anger other RC aircraft users when your 2.4GHz, 1,000mW video transmitter, possibly miles away, shoots down their plane(s). And, if there’s other RC operators in your area, you’re going to experience video corruption on your downlink anyway.

So 2.4GHz and 900MHz video links just don’t make sense any more.

Understanding that first, I Googled briefly and came across this product in the 5.8GHz band. I have no idea if it’s the best available or even how well it works in practice. But it looks pretty sweet to me, just at a glance. Not cheap but. :(

DSL2+ Upgrade and QoS Limiting Attainable Speed

A lot of people tell me, “Hey man, you’re really smart!” But times like these do make me question their judgement …

Some time back, our DSL line was upgraded from ADSL to ADSL2+. The reported downlink ADSL rate went from about 5,500bps to 16,000bps. However, the actual downlink rate as reported by speedtest.net barely increased at all. I figured, “Damn. They’ve put a limit on the back-haul at the ATM level and I’ll just have to live with it.”

But more recently, the guy who rents the cottage at the back of our property decided to get his own DSL connection, instead of sharing ours over the WiFi link. Low and behold, he gets the same ADSL rate (more or less) AND he gets more than double the actual download rate. Clearly, he’s using the same DMAC and on the same back-haul link. So what gives?

I use a D-Link modem, patched with latest firmware and a LinkSys WRT-54G, also patched for more features. He uses just the little ‘free’ box supplied by the ISP. He let me do some swap tests. Here’s what I learned …

  1. His modem on my line gives me 11Mbps
  2. My modem, connected directly to my iMac also gives me 11Mbps
  3. My set-up through the LinkSys WRT-54G limits me to just under 6Mbps
  4. If I increase the ‘total available downstream bandwidth’ setting in the WRT-54G QoS area from 6000 to 11500, then low and behold, I get 11Mbps through the LinkSys! :P

I use QoS (Quality of Service) because I have a couple of SIP telephone circuits in the house. This ensures that if someone on the shared network is doing a big download (or upload), any phone calls in progress don’t get adversely affected. But in order for the bandwidth management to work, the LinkSys needs to know what bandwidth is actually available in order to start limiting connections when it reaches its usable limit I simply forgot all about it! Doh.

Mystery solved. Solution? Turn off QoS, run through the speedtest.net thing, then set the QoS available bandwidths to just under what I actually have available. Now, it’s working a treat.

Podcasts — a Royal Delight

Call me slow, but I only just recently discovered podcastle.org and escapepod.org — two short story podcast collections, so far as I can tell so far anyway. Frankly. I’m enjoying listening to the stories so much that I haven’t even figured out entire what the two sites are mostly all about. *shrug* They both have About pages though, so if you don’t get hooked on the stories like I have, I’m sure you can read all about it for yourself. :D

While on on the topic of podcasts, just in case you don’t already know, there are some great Sci-Fi/Fantasy novel length story blogs at the following web addresses (also available through iTunes subscriptions) …

… and if you listen to those, you’ll hear promos for many more story podcasts, story writers, musicians and much more. If you’re at all like me, that list alone will keep your ears full of interest and intrigue for many, many hours. Have fun!

Living a Non-Conformist Lifestyle

A close friend just flicked me this guy’s social media/BLOG URL titled, The Art of Nonconformity.

He (Chris) seems to be one of those ‘one in a thousand” type characters, who just go out and LIVE like most people wish they could or regret they didn’t (myself included to a large degree!) He travels a lot, having a goal to, “visit every country in the world” before his 35th birthday in 2012. He’s university ‘educated’ and a conscious life-long learner. Like me! :P

I can see myself getting buried in Chris’ content for a good long time. His writing have so far been very interesting to me — and are indeed targeted at anyone not wishing to live their lives merely the way others tell them they should.

Haven’t got much time to rave on about Chris’ site right now, so why not just go check it out yourself!

Let me know what you think — leave a comment!

Potato and Nano-Tech Battery Technology

Commenting on a Google Buzz post about boiled potato batteries for emerging nations, a friend related how impressed he was with his electrical drill battery pack. Being the type I am, I replied enthusiastically with the following …

That will be the ‘A123′ branded (inside the pack) Lithium Iron Phosphate (LiFePO4) tech, heavily used by Dewalt. I have two 4-packs of those. Each cell have a nominal voltage of 3.3V and capacity of 2300mAh.

Far as I know, A123 were the first to use nano-laser techniques to make the substrate for the chemicals to rest in. They still hold tight to their patent, so I don’t think anyone else is doing it exactly that way yet. (A123′s primary target market is electrical vehicles.)

But there’s a whole new generation beyond that now, back into the lighter weight, more power for size/weight Lithium Polymer stuff. These are known as the ‘Generation-3 Li-Polys’ or simply ‘G3 packs’.

Lithium polymer cells typically do not have a (heavy) hard outer casing like the A123 cells. They are also rectangular so as not to ‘waste’ so much space, and have a nominal cell voltage of 3.7V vs. 3.3V. In the past, the G2′s and prior could not handle the type of charge current the A123′s could (by far) and had a much shorter cycle life. But that gap has really been narrowed won now with the G3 tech. The new G3 packs are very, very cool — especially when combined with 3-phase electric motors with total efficiency (including controller electronics) approaching 90% in some cases!

My Align(tm) T-Rex 500 Helicopter runs on a G3 2600mAh 22.2V pack (6-cell or ’6S’ as they’re known). It puts out about 300 Watts of mechanical power during average aerobatic flying manoeuvres, peaking almost a 500 Watts when pushed hard (at about 75% electrical efficiency if I recall correctly). Flight times are about 5 minutes — and that’s more than enough for my nervous system I can can assure you!


A similar version to what I have. It’s a very fun machine. But I’d just *love*
to have a T-Rex 700E! I’ve seen the 600′s fly and they’re so amazingly
stable and ‘floaty’. The 700 must be awesome.

Amazon patent ‘social networking’. WTF?

Oh dear. But how not surprising.

Not to be outspoken or anything, but …

I finally gave up on the patent system completely in late 2000 when I learned from a friend that the start-up company he worked for was under attack by a competitor who had somehow patented the idea (only recently at the time) that you could determine if a particular cellular comms module ‘had coverage’ by assessing the voltage on the signal strength (RSSI) pin of its radio chip. DUH. Being as that’s the only reason the chip manufacturer put the signal there in the first place and, besides the same standardised signal having been present on hundreds of radio chips and interfaces for many years, they had also fully (publicly) documented its purpose in this instance. So it all seemed a pretty clear case of an invalid patent.

But the start-up spent over NZ$70,000 of investor funds trying to get the judge to see that simple fact before giving up in disgust. As I recall, they continued with the product by adjusting the code to simply see if a call could be initiated as the method of determining coverage in boolean fashion. (And set about publicising that fact in the public domain as far and wide as they could so as to foil the rogue patent attorneys and their questionable client.)

Flip the roles around of course and you’ll find thousands of highly expensive, completely valid patents begin reduced to worthlessness for the same legal costs reason.

That’s just one of thousands upon thousands of similar stories since patents began. The original idea was good. I invent a bicycle and patent the two-wheeled form of transport. You invent the flip down stand so the thing doesn’t need a lamp post to stay parked upright. You pay me a licence for the original idea, I pay you a license for the nifty advancement, and we both go on to manufacture better bicycles. Now everyone, not least the consumer, wins. But long gone are those well intentioned ideas it seems.

Now you have this nonsense from Amazon as reported reported by PC World — Facebook, stop what you’re doing: Amazon has patent for ‘social network’.

In my perhaps not so humble opinion, the patent attorneys responsible for this embarrassment to all things good in the human race should be lined up and shot … or at least laughed at and ignored. Personally, I’d rather invite the tax man to dinner than partake of a single piece of bread with those low-lifes.

Patents seem to me today as little more than a tool used by the greedy to stay (or hopefully fail to get) wealthy.  Frankly, I don’t understand why anyone pays them any attention any more. Oh yeah. Legal costs of not doing so. I forgot. What a crock. *shrug*

Long live open standards and open source!

Another pingback test

I’ve enabled XML-RPC protocols on the company blog. This might make pingbacks work over there. Somehow I dout it, but here goes nothing …

Here’s the link to the pingback post on the company blog.

Pingback. What is it?

This is really just a test post to check that pingbacks are working between this, my personal blog, and ‘that’, one of my company blogs. (See below.)

WordPress is said to support pingbacks automatically. So, when I mention my blog post over at NZ Hosting’s blog, a comment should end up over there automatically — having been automatically verified as to this post actually containing a link to the blog over there. Clear as mud eh?! :P

I’m going to add a second link to a blog post where I first learnt how both pingbacks and trackbacks work, without which I’d not be writing this anyway, so it seems only fair. :D

Assuming this works, I’ll be fairly impressed. But I have to say, I can already see a couple of potential ‘gotchas’.
