Glorp findings – using count:

Conntinuing on the Customer/Order example from my last post, we might want to only send some ads to customers who have ordered at least twice in the past. For this we'd first have to cunt all orders of our customers who haven't ordered for at least 100 days. So the first step is to create … Continue reading Glorp findings – using count:

So here is the idea: I am struggling with Glorp … Continue reading Glorp Subqueries – notExists:

Seaside Learnings, pt. 123

In your delegating WATask or  WAComponent you will see the callback code run as if all was good, just the new components won't show up in th browser. This will take a long time to debug and you won't … Continue reading Seaside Learnings, pt. 123

Why many managers failed…

So one of my posts on the Pharo Mailing list just made it into the Pharo Weekly News Blog 😉

Weekly news about Pharo

to understand the power they could have in their hand. Here is a testimony on the Pharo mailing-list. This is why we should build powerful new solutions in Pharo 🙂

Stef

Petr,

I’ve been working as a Consultant for many big corporations (mainly in VA Smalltalk) since 1996. The situation you describe is very well known to me. But in my opinion there is no technical reason for this. It’s a managerial problem. Ever since IBM went out to their customers and told them to move to Java for the better ini the mid-90ies, managers wanted the Smalltalk projects to go away as fast as possible. Nobody asked why IBM was still happily using VisualAge Smalltalk internally at that time frame….

So the Smalltalk projects were declared legacy by Management. Replacement projects were started with big efforts and optimism. Some went well, some somewhat came to fly in a bit…

Seaside 3.2 Session timeout & let’s start a blog parade

Seaside 3.2 is not actually new, but we just recently switched to VAST 8.6.3, which ships with Seaside 3.2. Before that we were on VAST 8.6 and Seaside 3.1.x (x=I don't remember exactly).

Glorp/DB2 – Tip: Sorting case insensitive

If you are working with Glorp and DB2 and use #orderBy: you may have found out that the results of ordering by CHAR or VARCHAR columns may end up strange. DB2 assumes that a Small letter is less than a capitalized one. "Hans" is lower than "HANK". In my case this came obvious in a … Continue reading Glorp/DB2 – Tip: Sorting case insensitive
