Using 2 subreports in a jrxml template for as_pdf doesn't result in the expected output. But passing variables back to the master reports works at least 🤣#JoelKallmanDay

Some small improvements for #as_pdf 4 #plsql as_pdf 4.0.2 is much better than as_pdf3 :) And a second example:

I started to work on upgrading #as_pdf3 No yet ready for #ZugFerd but my latest test result is: Validating file "my.pdf" for conformance level pdfa-3b The document does conform to the PDF/A-3b standard.

Someone asked this week about password protection a PDF with as_pdf3. I once had that working, but I couldn't find any sources. I did some 12 years old source with code to add password protection to an Excel file. So I quickly added that to #as_xlsx before I loose that too 😃

I just wrote a new blog post about Implementing User Access Control in #orclAPEX with Oracle Identity and Access Management 📝 Get ready for part two, where we'll explore how to limit access to just the right group of people or manage their permissions✅ tm-apex.hashnode.dev/impleme…

It was a great day as a passionate Oracle APEX developer and I couldn't resist publishing a blog post about the new native QR Code and Barcode generation in Oracle APEX 23.2 ✨ lmoreaux.hashnode.dev/oracle… #orclAPEX

I did some more work on my #plsql #zstd decompresser. It parses now 100% of a 100 files test set😀 It only takes 60 seconds ⏱️😟 #plsql definitely needs some bit-fiddling functions 🤞

Look what I got at #apexworld2023. A book, not about #orclapex, but about my favorite languages SQL and #plsql. By @alexnuijten @patch72

Was playing around with MFA and my #orclapex demo application for as_barcode. Did you know that the Microsoft Authenticator app not only supports QR-code, but also an Aztec-barcode? github.com/antonscheffer/as_…

By the way, for validating the TOTP-code I didn't use dbms_crypto, as_crypto, oos_util_crypto, or any other package, just a simple query. Simple meaning just 30 lines. Finally found a good usage for standard_hash #orcldb #orclapex

Barcodes in Oracle APEX, without a javascript library? No problem. See apex.oracle.com/pls/apex/f?p… #orclapex #as_barcode #plsql #orcldb

I said "No problem", but that seems to be not true. The demo application is not available anymore, workspace not accessible, gone???? But is it related to #as_barcode? I don't know :) #orclapex

Added a howto github.com/antonscheffer/as_… to create a JWT with #plsql using #as_crypto in the #orcldb RS256, ES256 or HS256
