VASTGoodies just turned 10

As Adriaan just announced on his blog, VAStGoodies.com was launched the 27th of January, 10 years ago now. But not only that, just a few days before that milestone, another milestone was reached: the 1000th upload! The introduction of VASTGoodies was a much-needed and welcomed addition to the Smalltalk universe. Back in the 2000's the … Continue reading VASTGoodies just turned 10

What to do when VAST x64 (and Seaside) on Linux need a little help finding libcrypto.so

[update: I just updated the title of the post, because on other Linux machines,  like our test and production servers, there is a link named libcrypto.so in the 64 bits libraries path, so the change to the ini file is not necessary there... 20591215 0 lrwxrwxrwx 1 root root 16 Jun 20 13:29 /usr/lib/x86_64-linux-gnu/libcrypto.so -> … Continue reading What to do when VAST x64 (and Seaside) on Linux need a little help finding libcrypto.so

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:

Glorp Subqueries – notExists:

I decided to get back to blogging after a very long break. Since I am quite busy with our Kontolino! project, I also decided that I need to get back to blogging with small articles that require little time - but might still be useful. So here is the idea: I am struggling with Glorp … Continue reading Glorp Subqueries – notExists:

Seaside Learnings, pt. 123

Note to self: never, never ever try to use show:onAnswer: or answer: in an Ajax callback. 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

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). Among the numerous changes in Seaside 3.2 is the new session timeout configuration. Up to Seaside 3.1 the way to configure session … Continue reading Seaside 3.2 Session timeout & let’s start a blog parade

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

Expressions you’d probably never type

... and yet they give the expected result. I just tried this one, assuming it's probably worth a try, but it will most likely not work: String with: Character cr with: Character lf. Not that this is interesting or such. I was just surprised you can use with:with: to create Strings. Go back to work, … Continue reading Expressions you’d probably never type
