Internally at IBM we use BlueGroups to manage permissions for various services. It’s basically just regular LDAP groups inside of a Tivoli Directory Server. We have a web UI for managing those groups. Unfortunately the definition of managing apparently doesn’t include finding the list of groups you’re a member of. For this you need some ldapsearch trickery.

First, find the dn for your user:

$ ldapsearch -x -h bluepages.ibm.com -b ou=bluepages,o=ibm.com "(mail=NAME@CC.ibm.com)" dn

Then use that dn to find the groups you’re a member of:

$ ldapsearch -x -h bluepages.ibm.com -b ou=memberList,ou=ibmgroups,o=ibm.com "(uniqueMember=uid=SSSSSSCCC,c=CC,ou=bluepages,o=ibm.com)" dn


Disaster Recovery

Reality check: Does your disaster recovery plan defy the laws of physics?

Sure, it's always a middleware problem.

Working as a middleware admin? Then you should really check out t-rob’s latest post. This post works for any middleware you’re working with, not only MQ :-)

Project Jigsaw

Jigsaw will most likely be delayed again. This time until Java 9. The goals are ambitious, but given a first demo of this was shown at JavaOne three years ago, this is pretty disappointing. You can find the FAQ on Mark’s blog and join the discussion there or send your feedback directly to the Java SE 8 Comments List.


Amazon Glacier

Amazon yesterday released their latest Amazon Web Service called Amazon Glacier, a remote archiving/long-term storage service. The downside is that Amazon can take several hours to make your data available for download after you request it, but that’s not too bad when used as an archive or backup. You also can’t arbitrarily name objects stored in Amazon Glacier, as objects are named by the service when you store data there, so you need to remember which object is which after you store it.

Apart from the obvious use as a remote backup, which is kind of boring, this might be interesting for use as an archive storage to store things “just in case” for a limited period of time. I got really used to the Tivoli Storage Manager archive feature on servers. You just put something in the archive that you would rather delete, but don’t know if you might need it back in the next few months. It gets stored in the archive for later retrieval and if you don’t need it anymore it just vanishes from the archive after 90 days, or whatever timeout you set when storing it in the archive.

Wouldn’t it be awesome to have something like this without the hassle of having your own tape library? Amazon’s cost model even seems to favor this use. You don’t pay for incoming data transfer, monthly storage costs are rather low, and you only pay a penalty if you remove data earlier than 90 days.

Google Nexus 7

A few weeks ago after Google I/O 2012 I played around with my brother’s N7 he got there and now I need one too :)

It’s said that it will be released in Germany in September, so I still got a few weeks to go, but there is still one question open: 8GB or 16GB?

I think I should be good with 8GB, but who knows… :-/

Nokia Lumia 800

I’ve now used my Nokia Lumia 800 for the last four months and I must say I’m impressed. It’s not only the hardware design itself, which is excellent, but it’s the compact design and the simple software interface that I really like.

Everything I wrote in my post about choosing a new smartphone still holds true, but given nothing is perfect, I’d also like to report a few annoyances I have with this phone:

  • Nokia Maps and Bing Maps don’t show a compass because apparently there is none. - why nobody mentioned this in their reviews is beyond me.

  • Even though Bing Maps understands coordinates, Nokia Maps doesn’t. And Google Maps links sent from Android need to be copy & pasted as they’re not understood and linked to Bing Maps. This makes sending/receiving a location much less convenient than on Android.

  • Nokia Drive maps work offline, but Nokia Maps don’t.

If you find iPhones too gimmicky and the high-end Androids too large and hate Android fragmentation and its update craziness, this might be your perfect phone too. Play with it at a store and see if you like it… they don’t bite, even though the software is from the northwest. :)
