2013

Fifteen years ago I would spend six weeks writing the incorrect year on every cheque I wrote.

In 2013 I’ll be lucky to write a cheque during the year.

Browsers

I’ve been a long time user and supporter of Firefox – through all of the pains and memory hogging years. Before that I swore by Netscape Navigator.

I dabbled for a short time with Rockmelt – good idea – but didn’t seem to have the execution and updates.

I’m now back to trying Chrome. It’s improved a lot.

For fairness – Internet Explorer 10 is actually pretty impressive too. The ONE THING that I miss is a plugin that does adblock. There is a paid option for IE9 – but nothing for IE10.

Hyper-V and Windows Server 2012

Just loving Windows Server 2012 and the updated version of Hyper-V – it’s fast and furious on modern hardware.

The updated Linux support is great too – multiple v-procs – and great aware drivers for SUSE Linux.

Microsoft Dynamics CRM 2011

There’s a lot to be said about ease of use – especially when it comes to extensive customisation.

I’ve spent the weekend installing and building the “back office” for Grania’s business using Microsoft Dynamics CRM 2011 – and it’s been pleasantly rewarding. No code, no SQL, no UI hacking – and I’ve got a really solid, supportable CRM for her Music Together business fully working.

The best part is that the customisation is fully portable – and can be moved up to Dynamics CRM Online. That’s powerful.

The startup goes live

I’m the silent half of Grania’s business. The business process, policy and web monkey. I talk about marketing, lead generation, moving people through the funnel – she gets to teach pre-schoolers Music Together® classes.

The best part of all – telling friends that the business had gone live – and watching the Apache logs to see when people hit the site. It was a real warm and fuzzy moment to see .. one.. two.. three.. then more hits to the site. Early days; and friends aren’t customers – but one step has been taken.

Heat kills hard drives

It was hot this weekend – over 35°C (92°F) outside – and the home servers were suffering somewhat.

Western Washington is pretty friendly for servers – it’s usually cool – but we do get occasional spikes.

Normally I’ll add an extra fan to the rack – but this time I was away for the weekend. The firewall/IDS server hard drive collapsed and died. The alert monitors sent a final notification that the internal temperature reached 120°C. The final straw was a power outage for over an hour that triggered the UPS and graceful shutdown. On power restoration everything came back as expected – but the firewall sat with an unbootable file system.

It only took twenty minutes to replace the hardware – and it running happily at 42°C right now.

Postfix, IPv6 and non-delivery

Interesting issue this week with Postfix and IPv6. The webserver was resolving MX records as usual for delivery of blog notification – and also looking up AAAA records for delivery via SMTP over IPv6. Without a functioning route from home to the far end these were obviously failing and not retrying with the (routable) IPv4.

The fix was to force Postfix to only use IPv4 – there’s a great readme on this.

/etc/postfix/main.cf:
    # You must stop/start Postfix after changing this parameter.
    inet_protocols = ipv4       (DEFAULT: enable IPv4 only)
