Anything IT related (which is most things I say) :-)

Day 21- A picture of something that makes you happy

I think it was pretty obvious to anyone who reads this blog that the answer would be something computer/linux/open source related. :-)

My entire life is built around being with computers, it’s an integral part of who I am and a lot of my ethic, beliefs and friends have all been directly influenced by my interest and enjoyment of computing – particularly the open source side of it.

I love the ability to do anything with computers, create anything I want, solve any problem and do anything I wish – as it stands my entire life is computer based – communication, music, photos, writings, projects – I could quite happily sell all my assets other than my laptop and colo server.

So naturally, the picture has to be:

Day 15- Put your iPod on shuffle: First 10 songs that play

This question was clearly devised by someone who failed to realise that there is any music player *other* than the ipod.

For the record, I have never owned a portable Apple device (ipod/iphone/ipad, etc) nor do I intend to – supporting Apple means supporting a company that believes in locking down your freedom in proprietary systems.

I listen to all my music directly off my laptop – either with my Sennheiser HD212pro headphones or via a NAD3021i amp with some JPW speakers.

I set my entire music collection on shuffle, here’s what I got:

  1. Muse – Hysteria
  2. DragonForce – Ultra Beatdown
  3. Disturbed – Pain Redefined
  4. Rush – 2112
  5. Marillion – Bitter Suite
  6. Iron Madien – Run to the hills
  7. Nightwish – Ocean Soul
  8. Genesis – Jesus He Knows Me (live version)
  9. Hawkwind – Do That
  10. Kraftwerk – The Model

As you can see, I have a range of tastes. :-)

Day 12- How you found out about blogging and why you made one

I’ve been building websites since back when I was in primary school playing around with geocities websites (ah, those were the days ;-)

I set up jethrocarr.com back in 2006 which turned into a blog the following year and finally got upgraded in 2010 to WordPress.

No idea where I “found out about blogging” from, I’ve grown up with the internet all my life and having an online presence has always been something that I’ve done.

Day 07- A picture of someone/something that has the biggest impact on you

This is a tricky one, there have been a lot of people who have had a great impact – friends, parents, colleagues, so I’ve chosen the event that had the biggest impact on me.

This picture is from linux.conf.au 2006, which was the very first linux.conf.au I ever attended, held in Dunedin NZ.

I had just left college and was looking for a job in IT at the time, planning to sit my RHCE in a couple months (which I did and passed), before taking my first job.

To say that linux.conf.au blew my mind, would be an understatement – before then I was a geek sitting in my bedroom, compiling linux systems from source and attending college with a bunch of time wasters – at linux.conf.au, I realised that I wasn’t alone and that there were hundreds of ubernerds like myself out there.

It was an entire week of geekery with some of the brightest minds and celebrities of the open source work, I came away from it with:

  • Dozens of new friends, some whom I still talk to on a semi-frequent basis.
  • Realisation that most geeks are a pretty friendly, awesome bunch to hang with.
  • Discovered, it’s normal to sit around on your laptop all the time.
  • Knew that I was on the right path with a life in IT.

But linux.conf.au also served as a point in my life where I formulated my ideas regarding ethics, open source, freedom and many of the views that I hold to this day.

Probably one of the most memorable experiences in my life – I still go to linux.conf.au every year and it’s still my most favourite week of the year and I always come back feeling excited and renewed with awesome ideas.

Migrating Outlook profiles manually

As much as a I dislike Microsoft Outlook, we have a number of customers using it whom require support services and for the most part, it tends to meet their needs.

Like any Microsoft product, Outlook does have it’s own set of quirks and annoyances. In particular, the process of moving account mail and settings is much more complicated than competitors like Thunderbird who have a simple directory containing both config and files.

Whilst Outlook will use PST files for local email storage (don’t even get me started about PST files…) it doesn’t store the configration for accounts/settings as a file that you can copy across, so after moving to a new computer/account, the files can’t be re-imported.

This can be avoided if you use the windows migration tools, but these aren’t always appropriate for every situation, nor are they any use when you’re recovering selective bits of data from a backup.

The good news is that there is an (I think undocumented) way to copy the Outlook profile settings over to another computer/user.

To do so, run regedit and browse to the following location in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion
                              \Windows Messaging Subsystem\Profiles

Whilst it’s all just blob data, these registry values contain your account settings and details for Outlook.  By exporting the profile(s) from this location you can then re-import onto the new account/computer to retain all your settings.

When Outlook starts, it will remember all the settings (excluding passwords) and if it can’t locate the PST files in their previous location, it will prompt for the new one.

nut and shutdown timers

Network UPS Tools is a useful package for controlling UPSes with Linux servers – I recently moved to this package from apcupsd since it offers better integration with RHEL-style distributions.

Unfortunately the packages aren’t shipped with CentOS, so I’ve created some packages for it which can be downloaded from the Amberdms public repositories.

Most of the setup is pretty straightforwards (follow along with the online help) but the one issue that had me stuck was setting the time until shutdown, which would default to only two minutes – hardly enough for systems such as virtual machine servers.

Turns out this can only be adjusted by changing the settings on the UPS itself – in my case I was using an APC UPS.

You can get a listing with:

$ upsc YOURUPS

To change the timer (at least on APC BackUPS) you should run:

$ upsrw -u admin -p PASSWORD -s battery.runtime.low=SECONDS YOURUPS@localhost

The notes I read suggested that this should remain in the UPS settings, but in testing I found the value was reset – I suggest including the command in /etc/rc.local to ensure it gets run every boot time.

Day 01- A recent picture of you and 15 interesting facts about yourself

To start of the 30 days of me blogging challenge here is the day 01 post containing 15 (hopefully) interesting facts about me as well as a recent picture (or three since I’m bit of a camwhore).

1. I’m somewhat of a workaholic. Actually, that would be an understatement, I’m regularly doing 60 to 80 hour weeks and spending far too much time on a computer.

2. My family unit consists of myself, mum, dad and a younger brother. Dad is from the UK, don’t have much to do with that side of the family, and mum is from NZ. Tend to see mum’s parents semi-frequently, but outside of that I don’t associate with my extended family.

Like my dad always says, “Family stops at front door”. ;-) I just tend not to see a need to associate with them when I share no interests, just because they’re family.

3. I run a Wellington-based IT startup company called Amberdms, focusing on open source software and solutions. This means I get no sleep, work insane hours and am constantly hurrying around doing ten things at once.

4. I’m single. I’ve dated a bit and had a few flings, but never really formed a proper relationship with anyone. I recently started dating again to (somewhat) disastrous and/or amusing results depending on your point of view ;-)

5. According to my twitter followers, I’m known to be obsessed with cougars. In reality, I tend to subconsciously fancy older women, simply on the basis that we tend to interact and relate better.

My dating age range tends to be 18-30, lately I’ve been exploring the upper levels of that range and met some awesome ladies, although I think the age gap is a problem for some – I fear I may be cursed to be single until I’m in my 30s :-/

6. I’m younger than I look or behave – many people believe that I am around 25 but that’s a little off…

7. There are frequent debates about my sanity. In my defence, I’ve never been *proven* to be insane. I’d also like to point out that genius often borders on madness ;-) I might also mention I have a slight ego here…

8. I got into computers properly around intermediate school and was hooked on Linux within my first year of college (high-school for you American/international readers), starting off with Mandrake 6 and later moving to Red Hat 8 and onwards.

For a couple years I had my own Linux distribution (Jedo Linux) as a fun side project, which also taught me far too much about packaging, compiling and how a Linux operating system fits together.

9. I’m a born and bred Wellingtonian, although have been to a number of places in NZ and AU, mostly for business or conferences. Don’t have any particular plans to travel in the near future, I like it here and business somewhat ties me to Wellington.

10.  I’m a bitter, godless, atheist, I have very little time for religion – which will get me in trouble sometimes since I tend to open my mouth too much.

I think part of the problem is I can’t see any way someone could believe in religion and it really surprises me when I discover that someone I know has beliefs.

Having said that, I don’t really mind people who are religious for the right reasons (eg: caring about others, being good to people and having their own beliefs) rather than some religious believers who use it to try and silence or suppress things they dislike or try enforcing their beliefs via legislation or constant campaigning.

I’ve met some pretty amazing and caring people and cute couples who find that religion helps them, but I’m not sure it’s something I can ever understand.

11. Of course being a bitter godless atheist doesn’t mean I don’t have morals/ethics/beliefs – I’ve been lacto-octo vegetarian since 2008 and slowly moving towards veganism. This was slowly brought on by considering the fact that I’d never hurt a pet, yet was eating animals of equilivent intelligence, so I made the jump in 2008 and haven’t looked back.

I’m a pretty lazy cook, so I’m not exactly the most healthy vegetarian as you’ll quickly realise reading some of my posts/tweets. ;-)

I try to avoid being the whole “fanatical vegetarian” but I do have some pretty strong opinions about it and sometimes get into “vigorous debates” over the issue.

12. I flat with my friend Tom. Being a meat eater and opinionated, we tend to have interesting debates and philosophical discussions about just about everything anywhere.

13. I’m a strong believer in open source, my laptop runs Fedora Linux and running an almost entirely open source stack (there are a couple proprietary applications for work). Linux and open source has been a huge part of my life, both in getting me a job, but also as a way of making heaps of smart, fantastic friends and developing strong morals/beliefs about freedom, information, government and more. It’s probably one of the largest influences in my life.

14. At times I suffer from being somewhat egotistical and overly demanding with requests – something I’m trying to avoid.

15. I’m an infoholic – addicted to email, twitter and RSS feeds. I read almost every single message I ever get, which can take a bit too much time sometimes.

Upgraded to WordPress

For a long time I’ve been asked “when are you getting an RSS feed” and “when is your blog getting updated?”.

I’ve been pretty busy and haven’t had the time to upgrade my custom built system dating back to 2006, so I’ve finally decided to make the jump to WordPress, since it’ll make the maintenance and upgrading of it so much easier in future.

I’m also aiming to start blogging a bit more frequently, beginning with the 30-days blogging challenge that started up on Twitter – more about this soon – as well as being able to blog from my smart phone whilst on the go. :-)

At this stage, some of the old content is still missing, as I am slowly importing and reformatting/fixing a lot of materials – if you want to access the old site for anything, you can still reach it at: https://www.jethrocarr.com/old/

Linux on Lenovo X201i Laptop

Sadly after almost 5 years of loyal service, my beloved Libretto U100 recently started showing signs of it’s age by crashing randomly and struggling to keep up with my daily tasks.

To replace it, I wanted something both lightweight and portable, but also powerful to keep up with all the large documents and projects I’m working on.

I ended up selecting a Lenovo X201i laptop, Lenovo’s ultraportable model.

THE LAPTOP

With a 12″ widescreen LCD and weight of about 1.5kg, it’s certainly larger than my Libretto, but a great compromise between usability and portability. Having a fullsize keyboard is another major advantage and it certainly makes the laptop more productive on the go.

I also purchase the extended 9-cell battery, which gets me about 7 hours life, enough to get me through a day of customer meetings.

Over all it’s a fantastic machine, and with a Intel Core i5 and 4GB of RAM packed into the system it’s a fast system able to tackle everything I throw at it.
