If you noticed that Gmail, chat a few other Google Apps services were disrupted on Tuesday 10th December 2012, you may be interested in the official Google incident report (see the PDF linked to this post). Also, good comment on the event by Christopher Dawson on the ZDNet blog.

Offline Google Mail & Calendar

posted 14 Sep 2011, 06:24 by Francois Joubert   [ updated 14 Sep 2011, 06:42 ]

I contacted Google Support about my offline gmail and calendar problem and got the following as their first response:


Please if you haven't already done so clear your browser cache several times and try logging out and back in a few times, first in browser, then in apps.

To do this in Chrome:

- Click the wrench icon  on the browser toolbar.
- Select Tools.
- Select Clear browsing data.
- In the dialog that appears, select the checkboxes for the types of information that you want to remove.
- Use the menu at the top to select the amount of data that you want to delete. Select beginning of time to delete everything.
- Click Clear browsing data.

It seems rather drastic to have to clear down everything for all time but offline mail app now works. Only mail that has synced to your local machine will be available to the offline app (not surprising).

The app is currently unreachable.

5 Google Apps Questions

posted 8 Jul 2011, 08:58 by Francois Joubert   [ updated 8 Jul 2011, 09:05 ]

Q: How long does it take to migrate?
A: It varies by organisation size and the number of servers being used but normally 1 message per user per second is a good rule of thumb. So if you have 10 client servers each processing 10 users (for 100 users) you are getting 100 messages a second. If each of the 100 users has 10,000 messages (for a total of 1M messages), migration is 10,000 seconds or 2.78 hours. As you can see for a small organization it’s pretty quick.

Q: Is their any downtime?
A: Using Google dual delivery, Google servers operate alongside your current mail system delivering mail to both systems till Gmail mirrors your old system and then the old system is turned off.

Q: What is Postini and how much does it cost?
A: Postini is an email and web security service, it filters spam and malware before the message hits the mail service. Email retention can be purchased in a 1 or 10 year increments. Costs depend on whether the organisation has Google Apps for Buiness.

Q: What security options are available with Google Apps?
A: Google is FISMA and SAS70 Type II certified. A two step verification helps further secure Google accounts. Basically, you enter your password then a verification code is sent to a mobile device that has to then be entered into the account. This way even if someone has your password they can’t access your account. (Google Apps Security, pdf)

Q: Can Google Apps support multiple domains under one account?
A: Yes, multiple domains are supported either as separate domains or domain addresses. This way you can send and receive mail to joe.bloggs@somedomain.co.uk and joe.bloggs@somedomainagain.co.uk while only paying for the somedomain.co.uk Google account.

We need Standards

IEEE 802 Standards Committee Turns 30 (posted by Mike Fratto)
The IEEE 802 Standard Committee, turns 30 on March 13th and has been a major influence on data networking. Ethernet is the OSI layer two standard for data communications and in 30 years, the speeds at which Ethernet operates has risen four orders of magnitude from 10 Mbps to 100 Gbps, and the diversity of where it is used (LAN, WAN, wireless) has grown. Indeed, topics have exploded from frame formats to power management and study groups to analyze esoteric events like static discharge in copper cables. That's a lot of work for a 30 year old group. 

Clouds & Frameworks

posted 14 Mar 2010, 15:19 by Francois Joubert

I have been thinking about modelling business and came across Zachman's Framework in my reading. Without going into detail, it seems that the idea of distributed effort is central to the thinking. 

To be effective, you either have to be highly centralised in your organisation, which does not scale, or do something else. The something else so many businesses and other organisations have turned to is de-centralisation which brings with it a whole host of problems.

The holy grail in this endeavour is a completely distributed organisation with each distributed component operating efficiently and effectively interfacing with each necessary other component. This does require co-ordination and the adherence to strict standards. This implies that there is an authority in the system and that each component is accountable to that authority.

With the so-called Software-as-a-Service model comes a challenge because the authority (the business) cannot control the platform and readily define how the business components interface on a technology level.

Hello World

It had to be done! This was the output of my first computer program and I guess the first output for many programmers around the world. Now it is the first post on this blog. 

Rest assured I do not intend to discuss programming nor technology much; I aim to spend my time thinking about how businesses can use internet-based technology platforms and applications to solve business problems. It is all too easy to get distracted by the technology and what it can do in itself rather than its application in supporting business actions. This is partly due to our historic toy attitude towards computers.

My main focus will be Google Apps and other cloud-based technologies and how they may be used. These technologies are different to the recent tradition of installing much software on the desktop and in the data centre, and may seem rather toy-like in comparison.
