What can I say, I start this blog entry with a down side. The beautiful WYSIWYG editor that WordPress has, does not work on the iPad. That makes writing this not the easiest of tasks. Well, I downloaded the WordPress App and at lest I can type as much as I like.

Casio PB-100

The iPad…. Well I have to start this story a little while ago. Let’s say about 27 years. In my hand is my first (self bought) computer. Model PB-100 from CASIO. It’s a calculator with Basic dialect and all of 588 bytes of RAM. For me it was sheer amazing. I had 12 bytes output. I could conquer the world!!!

Not quite. In a certain way though yes I could. This little machine was about 12mm high, 16.5cm wide and 7.1cm high. It ran on two flat lithium batteries. If I’m not mistaken CR3202′s and they lasted for ever. I COULD take it everywhere and I pretty much did.

Of course 588 bytes quickly set an end to the unlimited potential. Causing me to go down the route of bigger and more desk bound computers. The flexibility was gone but a lot of power was gained. Nonetheless I missed the days of moving around with my computer. As a little side note the PB-100 is still in use today by my father. It’s still working well after 27 years!

Apple Newton MP2000

Years and years later, when laptops already roamed the trains, planes and office lobbies, I still missed the easy portability of that calculator. It was just always there. This was the time when the PDA revolution started. In succession I had a Apple Newton MP2000, a Psion Mx5, and several Palm devices. As a PDA the Psions were top. The Symbian/EPOC OS making all the difference. The one I did regret most selling though was the Newton. It was just leagues ahead of the competition.

Anyway for all the goodness of those platforms the input methodology was their biggest flaw it was always a compromise. Battery times were good though. What killed them all in the end were two things though:

1) the Internet. The graphical and display requirements were just too much for the processing power of these small devices and the displays were too small.

2) Connectivity to the outside world. All needed some syncing software via serial cable/USB and if you had multiple PCs you were in deep trouble.

I also have to admit here that I actually don’t like notebooks and laptops. I can’t really put my finger on why though. I had quite a few in my time also including MacBooks but they jut don’t give me the portability I want. They are to big to be truly portable and too small to replace my desktop (mainly screen size that is).

Finally Apple gave us the iPhone. I have a 3GS and that immediately changed the way I communicated and what I did on the go. I must contend I am a iPhone power user of sorts. Few games but a heaps of SSH, VNC, RDP, networking Apps stuff. I also like the absolutely brilliant way it converges calendars and email. This was the first time I was really all round happy with a mobile device…..if it weren’t for the screen size.

Psion MX5 PRO

And this is where the iPad now comes in. It is the right size, weight, power class and also very important; it doesn’t do too much. There is still a space for my iMac in all this. But it allows me to be productive on the go (like now), do my email and my surfing. It also streams video quite nicely so I can use it as a sort of TV.

The iPad certainly doesn’t do away with the iPhone. It is much more complementary. I wish Apple hadn’t locked the communication between the two devices down that much. I went for the 32gb option with 3G. The middle path between space and mobility. So far that looks a good decision.

So, my experiences…. Well my first experience was short lived. After about three hours the screen suddenly gave up mid flight. Very annoying that. So I rushed into town the next day and got it exchanged *phew*. So now I am on iPad v2.0 all going well so far. Let’s start with the down sides.

  1. Aluminum can get REALLY cold! But that’s rather due to our bad insulation in our house.
  2. Where’s the camera?
  3. Keynote doesn’t allow the use of a clicker (yet)
  4. No iOS4 (yet)
  5. WordPress WYSIWYG editor don’t work
  6. The USB power issues it has
  7. Where is the calculator?
  8. Where is SMS?

But all in all these niggles are minor. The good is that it’s absolutely awesome! After searching for decades this is the mobile device I always wanted. It gives me the flexibility without the bulk. The virtual keyboard is great. Little excursion on that… I can type nearly as fast on this thing as on a keyboard. The reason is probably that I never learned to 10-finger type. I still need to look at the keyboard. My hand movements to keys is random at best but it’s not slow. From the iPhone I’m used to not needing a tactile response and I actually find the glass that Apple uses nice to touch. Another cool side effect is that you can type easily in the pitch black.

Anyway… Oh yes, perfect device. The iPad like the iPhone follows the same principle of being more of a window on your data. So your emails and calender are just aggregates of your real services like Gmail or Exchange. So the iPad actually doesn’t save your stuff locally. This, in the age of Cloud Computing, is a good thing. Our data is ever more on-line. The need to have it locally is evaporating quickly.

I’ve now shown the iPad to a few people and the response is phenomenal. It’s like a no-brainer selling this thing. Switch it on, 50% sold and use it for 30 seconds…sold. This is the kind of device most people didn’t know they have been waiting for. The use is next to instinctive, no explanation necessary. Even ardent Apple nay-sayers are sold on it. Oh and I just wrote the last two paragraphs easily on the bumpy bus. Even a netbook would have been awkward in this situation. My only problem is that I am now getting motion sickness. ;-)

So in all, I definitely see this device as a milestone in computer and interface development. I am convinced we will look back on it like we do now on the first Macintoshes. It is also a much more revolutionary device than the iPhone. Where that was evolution of a concept this is revolution. The whole expectation of how personal computing is understood will change. Maybe it won’t be Apple selling the most devices in the end but neither did the Macintosh but it still was a revolutionary product (btw has someone already hacked an iPad into a Macintosh shell?).

Have a look at the iPad if you have some unused €£¥$ lying around! Don’t if you don’t. The temptation is just too big. :-)

This year the Oceania CITCON was held in Wellington to my huge delight. It was a first attendance for me.

I won’t go into detail about what was said and done because the website has a good Wiki where you can read-up on what went down. I hope all the scribes put up what they have. There should also be some audio tracks up there soon. This post is mainly about me posting some rough & dirty pics. AND of course to rave about how AMAZINGLY GREAT this unconference was. Lots to take home and brilliant people in attendance!

Thanks again to PJ and Jeff for helping us do our own conference! Great stuff!

Starting us all off To CITCON (speak KITKON!!!! VERY IMPORTANT!)

So…..what’s on the menu

Lively discussion

Now this is what I call OFF TOPIC

CI tools and the pro’s and con’s

I created my Twitter account sometime in 2009 but just couldn’t figure out what to do with it and what it was for. So I dropped the whole subject and fired up FaceBook.

2010 and WeekendTesting is gaining traction. In the process of getting involved I was confronted multiple times on how I could NOT have a twitter account. So in order to see what the fuss was about I re-activated twitter a couple of weeks back. Mainly for the whole testing scene thing.

This was during the same time the ugly FaceBook-privacy monster reared it’s head. So the motivation to look for an alternative communication channel was high.

After a few weeks of being tested-twitter-tester here’s my verdict: AWESOME!!!!

I have learned more about testing, test-tools, methodologies in about 3 weeks than in the last year (OK, I do exclude that dice-game-thing with James B. from that)! Twitter is like a huge meeting/melting of minds machine. I love it.

Unlike FaceBook it is focused. The 140 chars is annoying but extremely helpful in concentrating thought and communication. FaceBook is personal and tends to be mostly bla-bla. Cool for catching up with mom but not for debating testing or communicating information quickly. FaceBook is a wasteland when it comes to progressing your subject at hand. Twitter is the opposite.

I am encouraging the uptake of twitter as a tester. It helps the trade, it helps your know-how. FTW

Oh and my twitter account: @Oliver_NZ

About three hours ago I got involved in a twitter-discussion with James Bach (@jamesmarcusbach) and Michael Bolton @michaelbolton). The discussion was all about how to call automated testing in conjunction with exploratory testing (ET).

The knee-jerk reaction would be to call it “automated exploratory testing” or “exploratory test automation”. Sounds good and without much ado we could put that into a test strategy/plan of some sort. But… what are we really saying? Just put yourself in the shoes of an unexperienced project manager or line manager. I could see a converstationlike the one below:

Tester: “We will be doing automated exploratory testing!”

PM: “Cool! I like that idea. …hmmmm… so you mean after some test scripting we can get rid of all those testers! Wow! Double cool!”

Tester: “No, no”

PM: “Getting confused here. Alredy wrote here ‘decrease test effort by $50k’.”

Tester: “That’s not what I said. I meant….”

PM: “So no automated exploratory testing?”

Tester: “No. What I meant was….”

PM: “On a different topic altogether,….”

Testing is really great in choosing terminology that misleads non testing people in not getting it. This being one example.

What we want to say is that exploratory testing can use automation to facilitate the process of exploring. In the wider sense automation is just one part of our “bag of goodies” that we carry around. It is a powerful and sometimes inevitable tool but it does neither exploring nor testing. All automation can really do is checking (check out Michael Bolton’s blog on checking vs. testing http://www.developsense.com/blog/) and supporting manual testing.

So I’d suggest something like “tool-supported exploratory testing”. It clearly defines action and scope. John Bach (@jbtestpilot) commented that the dash based names were not so ideal and I do tend to agree. For the moment though I’d see it as the only really viable option bar something completely new (like Bionic testing, Remote control testing – thanks John).  I personally would love to have an acronym like ETX. I have so far failed at finding the long version for ETX though.

What this discussion has sparked in me though is to think twice about the terminology I use. The pitfalls are plenty and easy to fall into. So my advice to testers is to start caring about what you call things. It might propell your testing into a favourable direction and do away with the constant need to correct mis-conceptions.

Thanks James, Michael, Ben (Simo, @QualityFrog) and John for a great twitter session!

A while ago I blogged about my absolute love for my Sennheiser PX 100′s. They are truly astoundingly good headphones for use with iPods and other mobile sound sources. The quality getting up there with big headphones that cost a whole lot more. So….. I lost them. Looked for a week and then gave up.

So I started looking for a new pair and to my surprise discovered Sennheiser was nice enough to have brought out a new model. The PX 100 II’s.  They have had a slight or not so slight update around the edges. I think the main things are:

  • Broader and tighter headband
  • One-sided cable with other ear cable going through headband
  • Updated speakers
  • No more case (but a nylon bag)

After searching the Internet there were lots of reports either way. Some said the sound was too basey, others said the sound was great. So after a couple of weeks of listening to them I think I can add now my own analysis.

  1. The sound is slightly different. In my opinion better and still the stellar PX 100 sound. A+
  2. The single cable connect thing is an absolute godsend! Just for that I’d buy them. No more feeling for the three dots to know where left is ;-) A++
  3. I like the firmer headband. It’s better when listening lying down and it feels much more sturdy in general. A+
  4. Downsides…..none.

Looks again like I’m a fanboy. I didn’t really set out to be one, being very cautious because of the different reports. In the end they just blew me away as the original PX 100′s did at the time.

One week later my old headphones turned up and now I have both. So far haven’t touched the old ones. The II’s are just so much more convenient and easy to use. I know that sounds like an odd thing to say about headphones but Sennheiser made them so much more usable. I am very thankful I did end up buying these even though the old ones turned up again. I am even thinking of selling my old ones because I can’t think of where I’d like to use them anymore.

So there you go. My fanboy endorsement for the NEW Sennheiser PX 100II’s.

    Well, the first step is done. We have just had the first ever WTAZ session! And it went great! *yay*

    The objective was here:
    http://groups.google.co.nz/group/software-testers-new-zealand/browse_thread/thread/6cbee3a6fb040310

    The raised bugs can be seen on http://bugrepository.com – project WTANZ01

    The transcript is here: WTANZ Session 01 18-04-2010

    As you can see the session was very lively and we had a really good attendance for a first time Weekend testing session. We pretty much kept to the time-frame of 2hrs.

    The goal was to test the mortgage calculator on Sorted.org.nz. This is a popular website in NZ to learn about finances and things like retirement amongst others. From the word GO everybody really dug their heels in. One of the first insights was that there seems to be quite a big discrepancy when comparing results between various interest calculators. We really didn’t quite get to the bottom of that but it was interesting that a simple seeming thing can have so many “interpretations”.

    Further testing quickly showed the obvious. This website has NO validation checking but….. it doesn’t fall over either. No matter what you threw at it it would process the results. Never mind if the answer was correct. For details see the raised defects.

    The testing then focused on usability more general usability and browser testing. This might have all been  bit much for one session but nonetheless there were some good learning points to take home (check from log time 19:25 onwards).

    The discussion after highlighted that in such a high pressure testing situation most used the ET path. Some ideas around planning were done and shared with some good insights. I’m sure everyone could take something home from this.

    All in all great fun and great sharing. It all made my facilitation role so much easier :)

    So after all the butterflies I’m glad it all went well and we’re all looking forward to Marlena’s session in a fortnight.

    Also have a look at Ram’s blog entry that gives even more detail on what we did.

    Cheers & till next time!

    This weekend we’ll finally have our own Weekend Testing chapter in Australia & New Zealand! It’s been a few weeks in prep but it’s finally happening and I’m excited.

    weekendtesting.com

    Oh, you probably won’t know what Weekend Testing (WT, http://weekendtesting.com) is! So let me explain… This WT stuff was “invented” in India and is spreading the globe. The aim is that Testers learn from other testers while using their skills. So the low down is, at a certain time on the weekend and undefined number of testers meet on a Skype chat and a facilitator then poses a task/mission. The testers go and do their stuff for an hour and then come back and discuss what they did and why.

    The success has been quite phenomenal so far. There are three chapters in India and one in Europe. Because the time zone differences are quite extreme for us here at the other side of the globe there was a need to start our own chapter. So….

    18th April is the first session
    6:30PM New Zealand time and
    4:30PM AUS time (east coast).

    For more details have a look here: http://marlenacompton.com/?p=692

    I started using Ubuntu in earnest with 8.04 and 10.04 will mark 2 years of using Ubuntu at my work desktop. I am a Mac fanboy but in the office I have the choice Windows 7….well that is about the only choice. I decided to go rouge and run Ubuntu way back when. It works quite well for me in conjunction with CrossoverOffice. There are definitely nigglies and I wouldn’t suggest running it at work if you’re not IT savvy. Running it as home OS is a lot simpler because you are not dependent on Microsoft back-end services.

    Anyway 10.04 is about to drop on us and it is a LTS release (Long Term Support) which is nice. It has lots of new cool features and the design has improved a little too. So have fun using it!

    In NZ the government has declared that raising the literacy and numeracy rate is extremely important to the economic growth of the country. That is very commendable but…. THEN WHY THE H*LL ARE BOOKS SO DARN EXPENSIVE HERE? No wonder nobody reads. It’s like 3-4x more expensive buying the book than the DVD. Even Blue-Ray disks are cheaper. For the price of a mid price book I can get the DVD and the DVD player to match.

    So my civil duty it is to tell my fellow new zealanders about www.bookdepository.co.uk. It’s like Amazon but it has a distinct advantage…..FREE GLOBAL DELIVERY!!!! Now that is music to a Kiwi’s ears. No more waiting until you have US$150 worth of books to order from Amazon. Get them in your post box for the price of a book. And that price being that what the book really costs – before our kind bookstores put the gold-lining on the price.

    Bookdepository has a very good selection of books and is sometimes even cheaper than Amazon (depending on exchange rate). The fastest delivery (and we have already had dozens) is 4 days with 5-6 being the norm. The longest was about 2 weeks. Every book is sent separately so books that are not in stock don’t delay books that are in stock.

    All you bookworms out there rejoice and order to your hearts content!

    This will cause more kiwi $$$ to go off-shore and will force our bookstores out of business. But…see it from the positive side. You’re doing the country a service. You are supporting the upward trend of literacy and abolishing these ridiculously high retail book prices. Let’s force them to re-think what they are doing.

    Oh and… Mr. Key you can probably save a whole lot of tax-$$$ if you start ordering schoolbooks from overseas ;-)

    Ubuntu Linux is my trusty fellow at work. It is ideal for all those tasks I need to do. I have been running it from version 8.04 onwards. Now it is nearly time to upgrade again with 9.10 just around the corner. This will be another LTS release (Long Term Support). So here’s the countdown….

    I have checked out the alpha and beta releases and they look spectacular. Definite improvements over 9.04. I’m also very interested in the advancement of the server side with cloud computing being the big new thing.
