Happy new year 2012

pierrekoerber — Sat, 07 Jan 2012 05:32:32 +0000

New year, new objectives…

Last year I have migrated my site to a wordpress database. This year a have rebuild my old site with the amazing Bootstrap from twitter (http://twitter.github.com/bootstrap/ ). Why this comeback ?

1. WordPress is time consuming to manage. When you have installed wordpress on your server, it will be time consuming to keep it up to date. This is not my priority to do some sys admin so I just prefer to have static page with a link on my blog on wordpress.com.

2. Less well indexed… it’s seem to me that the whole stuff is less well indexed. We will see this year.

3. Harder to maintain static pages…

4. With bootstrap I can do my site very fast and I get more control on it.

And you what are your experience with wordpress ?

Greetings and happy new year.

xPages or not xPages

pierrekoerber — Thu, 10 Mar 2011 19:55:16 +0000

Are xPages a leading technologie ?

Obviously not. Of course Lotus has done a big effort to improve the gap between lotus notes and the today’s technologies, but they fail. The web has grown and they have choose the heavy choice of java and dojo.

What do you think ?

Coming next… dynamic class loading in lotusscript.,. stay tune !

Agent to create a backup of you names.nsf weekly

pierrekoerber — Mon, 24 Jan 2011 07:58:38 +0000

As an administrator, I often need to put me back in time to check something on the domino infrastructure. My Domino Domain is very small so I can afford to make a backup of my names.nsf every week.

This class, creat a copy of each documents of the names.nsf, zip it and attach it to a document… enjoy !

Generating an excelsheet with POI…

pierrekoerber — Thu, 23 Sep 2010 13:49:26 +0000

It’s very easy for an lotusscript developer to generate an excel sheet with some OLE… but when the code should be run on the server it’s getting bad.

My last entry was about to pass a vector to the java API from lotusscript. Here some background to create the excel sheet with POI.

Of course you should customize this code to fit your solution. If it run on the server with a lot of instances, remember to do some stress tests to avoid some servers issues.

Greetings…

First get – POI Export with poi 3.2

Dynamic arrays in lotusscript with ls2j

pierrekoerber — Thu, 23 Sep 2010 13:45:04 +0000

Last week, I was facing a tricky issue. I wanted to use some java to create an excel sheet. The POI java API requires a java vector. I created a dynamic array in lotusscript (to adjust the numbers of rows of my excel sheet) but when I called the POI API I’ve got an ugly error. The trick is to declare a variant, then affect the dynamic array to the variant and pass it to the JAVA API. So easy !

I wanted to do a lotusscript FT-search of the non existence of a field in documents… let’s begin some head aches… hopefully with google I found quickly a solution.

My iPad and me !

pierrekoerber — Sat, 04 Sep 2010 09:45:36 +0000

Already one month that I’ve got my iPad… and I don’t know how I have lived before it. I’m a

computer professional and I’m not afraid of a computer. So when Steve announced the iPad I felt a
little bit frustrated because I was wondering what will be the use of this big iPhone.

This tool is very cool and I want it to surf the web.

The cons

1. Don’t use it for writing

I’m a french speaker. So when you want to do special french characters it will takes you hour to
write something. It ‘s adapted to write short text and commands. It’s a little bit hard to
navigate in a big text in an edition mode.

2. You need a computer

Without a computer, you could do fast nothing. At the first start up iPad claims to be connected. One
big part of the iPad miracle is all the pre-processing done on your computer.
I tried to do some RDP… it not very conftable. You need a computer to upgrade the system

3. Wellcome in the Apple world

You are in the club… but hard to go out the fence. Everything is locked down by default. You
can unlock it but it’s your responsability.

4. Apple store… give me you money.

The apple store is a cash machine… for apple. You’re sollicited to pay for everything on the
iPad and sometimes it’s not for the goods. Apple has succedded in the micro-payment strategy.
Nothing is very

5. Keep it synch

The synch process it a little bit slow (I’m working under windows)

The pros…

1. It’s amazing to surf with your finger

It’s a pretty cool experience to go and conquer the web with your finger. The zoom is so easy and
it’s too cool to click anywhere.

2. Just open it and your surfing

Before that when you need to go on the we if you’re not on your computer it takes you time to do
it. Now just click, the iPad is ready and go… no wait !

3. Application on one click !

The same for the application. No wait… everything is fast… it

4. And it goes on, goes on…

The battery is very cool and it is serious… you can “work” for 10 hours. I understand why there
is no USB and Webcam and other battery consumer… the iPad is optimized and you can feel it !

5. The perfect tool for non-geek…

My little boy and my wife are what we can call technically, non-geek person… and you know what,
they feel confortable with the iPad. This is the perfect demonstration.

6. And too cool the appStore…

Here it’s like when going to the … you can find everything but nothing. A lot of stuff but

Conclusion… I think that Apple has done a kind of miracle. When I’m facing my computer screen
which is very big… I often wonder to do it with my fingers… The iPad has open a new area in
the computer world. Now the computer won’t be personnal again.
