I just found an email bug in iOS 7.0.2 – if you open a draft email where the from address isn’t one of those listed against the account you can edit and send with the usual “swoosh” but the mail is neither delivered, copied to your sent folder nor otherwise recoverable without recourse to backups.
Steps to reproduce:
- On another system, create an email with a from address not registered with your iOS device
- Open the draft on the iOS device and hit Send
- You get the “swoosh” but the email isn’t delivered, is not in your sent folder or indeed anywhere I can find
If I add the from address to my iOS settings for that mail account and try again it works as expected.
Verified on my iPhone – I’ve not tried the iPad or iPod and haven’t tried other ISPs (it could be provider specific).

Dimensions of National Culture – fascinating application of science to cultural differences by Gerte Hofstede. You may have heard of the Big Five personality traits, here’s the same thing for countries. From Hofstede’s web site:
The values that distinguished countries from each other could be grouped statistically into four clusters. These four groups became the Hofstede dimensions of national culture:
- Power Distance (PDI)
- Individualism versus Collectivism (IDV)
- Masculinity versus Femininity (MAS)
- Uncertainty Avoidance (UAI)
A fifth Dimension was added in 1991 based on research by Michael Bond who conducted an additional international study among students with a survey instrument that was developed together with Chinese employees and managers.
That Dimension, based on Confucian dynamism, is Long-Term Orientation (LTO) and was applied to 23 countries.
In 2010, research by Michael Minkov allowed to extend the number of country scores for this dimension to 93, using recent World Values Survey data from representative samples of national populations.
There’s a tool on the site to compare countries. For example, you’d have thought Sweden was very like Denmark – according to his research there are differences. There’s also an iPhone app called Culture GPS to give you the same insight while on the go.
Internally my company gives us access to GlobeSmart:
GlobeSmart is a powerful online tool available to [employees]. It provides information on conducting business effectively in over 50 countries. Developed from extensive research and interviews with business people from each country, it is organized into more than 50 continuously updated topics. It helps you learn how to communicate, build relationships, and collaborate with new and existing colleagues and customers around the globe.
Lots more to GlobeSmart than I can cover here, they do refer to Hofstede‘s work.

Found my iPhone refusing to send email today despite months of reliable operation. No obvious changes I’m aware of since I last successfully sent email. It reported:
Cannot send mail, no password provided for account
Strange – the password was set. I tried entering the correct password again – important data point, no “Verifying …” cycle. Still failed. Set it to something wrong, “Verifying …” ran and confirmed it was wrong. I set it right, no “Verifying …” cycle. Still not working. Cold booted the phone (power + home held until you see the Apple logo). No joy. Killed Mail. No joy. Hmm.
Finally fixed it. I set the password incorrectly, let the “Verifying …” cycle run (and fail) but saved the settings anyway. Tried to send email, password incorrect. Set the password correctly, verifies OK, now it all works.

As a member of the Institute of Advanced Motorists and a regular cyclist I’ve wondering whether the Goals for Driver Education (GDE) matrix can be applied to developing cyclist safety. With my own children learning to ride on the roads it’s more pertinent today than ever.
Briefly the matrix maps four levels to three areas. The levels are:
- Goals for life and skills for living
- Goals and context of driving
- Driving in traffic
- Vehicle Control
The three areas are:
- Knowledge and Skill
- Risk Increasing Aspects
- Self Assessment
It’s a hierarchical model and driver/cyclist training typically focuses on the lower two levels. Various road safety organisations are promoting focussing on the higher levels as a more effective means of developing safer drivers.
For example, you may have great control, be experienced in traffic, but you just missed your turning and you’re late – suddenly you find yourself taking more risks.
The lower levels are much easier to explain and teach. The highest level is about who you are and your attitudes – much harder to fix but surely worthy of the investment.

I just realised why I don’t use RSS readers very often – you can’t create content with them.
I doubt there will ever be one tool to rule them all – Facebook is trying very hard in this area – but I want to minimise the number of ways I have of keeping up with and contributing to communities both inside and outside my company.
To successfully follow communities an RSS reader beats visiting each one manually but if I want to contribute I have to step outside the RSS reader.
RSS makes perfect sense for (say) news, eg The Guardian – where I do use RSS – but apart from that I don’t ‘consume’ that much (note to self, reconsider intent to purchase an iPad 2).
When it comes to active participation I find myself being sucked back into communities that run on email – the lowest common denominator in more than one sense. Other communities get less attention, eg Facebook. In some ways the communities that are a priority for me do tend to end up in my INBOX. Others have to wait until I have time to browse.
Are there any RSS readers that will let you post content?
A quick search suggests not and I suspect the problem is not the tools but the lack of a common protocol to post content.
Perhaps another way of putting it is that I tend towards producing and less consuming?

I recently started running Thunderbird 3.0.3 on Solaris with a large 2000+ mail folder hierarchy accessed through IMAP. It rapidly becomes unusable. Problems seen include:
1. In stderr the following sorts of message are seen:
(thunderbird-bin:7792): Gtk-WARNING **:
Error loading icon: Failed to open file
Too many open files
2. The GUI pops up errors like this:
Unable to open the summary file for XXX. Perhaps there
was an error on disk, or the full path is too long.
Where XXX varies.
3. Some icons in the menus appear as a blank page with a
red cross (x) in them.
4. Mouse and keyboard operations silently fail.
Restarting Thunderbird corrects the problem for a few minutes but then problem returns.
pfiles(1) against the thunderbird-bin process shows file descriptors being limited to around 256:
$ pfiles $(pgrep -u $LOGNAME thunderbird-bin) | tail
The open files are predominantly the local cached file of the IMAP folder.
Some internal discussion found the following workaround, hurrah!
$ ulimit -n 2048
$ export LD_PRELOAD_32=/usr/lib/extendedFILE.so.1
Essentially it’s hitting the 32-Bit stdio 256 File-Descriptors Limitation. See the man pages on
Solaris bug logged (6955102) – though I’m not sure whether the fix is to have the workaround in the Solaris start scripts or work with the Thunderbird developers to have it handle FDs better.

Many moons ago Sun introduced SunTOPS (Sun’s Talent Optimization System) for development planning. Included in the notes, sadly I no longer have a copy, was this intriguing diagram:
I’ve since found what I believe to be the underlying research behind this, it’s the 70/20/10 model. There is a reference to it in the Princeton University Learning Process.
I’ve not found a reference to the idea that development plans usually turn this in its head – in other words, we incorrectly assume that development is 70% training, 20% learning from others, 10% job experience. If anyone knows where this came from please let me know.
According to Princeton:
70/20/10 learning concept was developed by Morgan McCall, Robert W. Eichinger, and Michael M. Lombardo at the Center for Creative Leadership and is specifically mentioned in The Career Architect Development Planner 3rd edition by Michael M. Lombardo and Robert W. Eichinger.
The seriously chunky and expensive The Career Architect Development Planner isn’t in my local library or searchable on-line. I’d love to take a peek
Update – 13th May 2013
Since writing that article I found a blog post Let’s kill a few learning holy cows – 70:20:10 is dead (or at least seriously ill) which states “If you examine the peer reviewed articles, there is not one single empirical study that validates 70:20:10″.
Doesn’t mean it’s wrong, it’s just that there’s no supporting evidence.
Interesting, I wonder if this is a bit like Albert Mehrabian’s widely misrepresented “7%-38%-55% rule” – there’s a very specific case for which it’s true. Or is it largely true, but evasive in its supporting evidence?

As already blogged by Chris,
With the push of this feature into Solaris:
6874309 Remove NIS+ from Solaris
PSARC/2009/530 Removal of NIS+
a bit of Solaris history is made. The namespace that was to replace NIS (YP) has been survived by the system it was to replace.
My first day at Sun Microsystems in 1995 was the day I first touched NIS+ having geekily read and re-read the white papers prior to my joining. Chris was already service’s recognised NIS+ expert world-wide so I was in excellent company as tentatively typed my first
To witness its removal is eerie to the least. The irony is that I’m now the manager responsible for the team that just removed something that’s been been a golden thread running through my career at Sun for what is almost 15 years. I’ll raise a virtual glass to all the people who’ve worked on it and with it – cheers. As Chris said, “it was fun”.

Interesting article in the Guardian on crowdsourcing – companies using large numbers of distributed people rather than technology to solve problems.
While not directly related to working from home it struck a chord with me. I commented on Rands’s article on “The Pond”. One of the things I wrote was:
“One concern whether remote or not is that if my work is so precisely defined then the company may decide to contract the work elsewhere, possibly off-shore. Human nature means that the unquantifiable work that keeps me valued is so much more visible in the pond.”
Occasionally I entertain the idea of working remotely so that I can live where I want to live and all the other good stuff around home working. The article was a useful reality check and had me thinking about where I and the people I work with add value.

Another extraordinary TED presentation, this time by Barry Schwartz on The real crisis? We stopped being wise. It echoes a theme I’m seeing in many areas around how an over-attention to goals, metrics, rules, incentives, etc not only demonstrates a lack of trust by those setting them, it actually encourages the very behaviour they are seeking to avoid.
I’m a little leery about SMART goals. It’s in all the management books of course and as a manager I’m expected to set them but we tend to over-rely on them. As Barry says in his presentation, we need rules, we need incentives but not more and more of them. They have their place but understand the limitations. I also recommend When Goal Setting Goes Bad which discusses the working paper entitled Goals Gone Wild: The Systematic Side Effects of Over-Prescribing Goal Setting.
Barry talks about how any scheme of incentives can be subverted and calls for wisdom and ethics to be nurtured. There’s a Wired interview with Barry where he says:
“When you rely on incentives, you undermine virtues. Then when you discover that you actually need people who want to do the right thing, those people don’t exist because you’ve crushed anyone’s desire to do the right thing with all these incentives. And if you bring in a new set of people to replace them — virtuous, moral people who want to do the right thing — and they’re subjected to the same set of incentives, they’re going to become just like the people they replaced.
I’m not talking about getting rid of incentives; people have to make a living. But people need to understand that rules and incentives aren’t enough…. The more rules and incentives you have, the less wisdom you will have. There needs to be room left on the one hand to nurture in people the desire to do the right thing and on the other hand to give them the tools so that they’ll know what the right thing is. This incredible pressure to increase payoffs is an obstacle to doing the right thing. You will never be able to create a system of incentives that rewards people for doing the right thing. The system of incentives may start out that way, but very quickly clever people will find ways to … game it.”
Amen to that.
