FW: Cool VFP stuff - Field repositories (by John Koziol)


The real question is.-. When does this get into vfp? Giving visual foxpro oop data management would be totally amazing!

Maybe in the next version...

"A field repository is kind of like domains in other databases or parent classes in OOP terms. You can create and maintain a repository of fields with attributes that are maintained by linking table fields with the repository fields. Any change in the repository get implemented in tables using the shared fields.


Using a field repository, though, LastName C(30) would be a shared, common field and guarantees the attributes are exactly the same from table to table. So, as I said before, you gain in your data some of the RAD pros you get from using object parent classes. Kind of a data structural inheritance.

Several VFP tools, commercial and public domain, incorporate this concept under a variety of names. Cool concept."

Blogs and RSS come to Microsoft.com

MS has just introduced their portal and it's pretty comprehensive. Nothing quite like learning that some people use AIM instead of MSN messenger, or that there really may be a need for supporting 4 monitors ( Cyrus Complains ) However, it's really a great sign that MS is serious about supporting the blogging community which seems to have um, exploded in size in the past year.

Elevating Project Specifications with Three Insightful ChatGPT Prompts

For developers and testers, ChatGPT, the freely accessible tool from OpenAI, is game-changing. If you want to learn a new programming language, ask for samples or have it convert your existing code. This can be done in Visual Studio Code (using GitHub CoPilot) or directly in the ChatGPT app or web site.  If you’re a tester, ChatGPT can write a test spec or actual test code (if you use Jest or Cypress) based on existing code, copied and pasted into the input area. But ChatGPT can be of huge value for analysts (whether system or business) who need to validate their needs. There’s often a disconnect between developers and analysts. Analysts complain that developers don’t build what they asked for or ask too many questions. Developers complain that analysts haven’t thought of obvious things. In these situations, ChatGPT can be a great intermediary. At its worst, it forces you to think about and then discount obvious issues. At best, it clarifies the needs into documented requirements. ...

Programmers vs. Developers vs. Architects

I received an email this morning from Brandon Savage 's newsletter. Brandon's a PHP guru (works at Mozilla) but his newsletter and books have some great overall perspectives for developers of all languages. However, this last one (What's the difference between developers and architects?) kind of rubs me the wrong way. Either that, or I've just missed the natural inflation of job descriptions. (maybe, it's like the change in terminology between Garbage man and Waste Engineer or Secretary and Office Administrator) So maybe it's just me - but I think there's still a big difference between Programmer, Developer and then of course, architect. The key thing here is that every role has a different perspective and every one of those perspectives has value. The original MSF create roles like Product Manager, Program Manager, Developer, Tester, etc - so every concept may pigeon hole people into different roles. But the statements Brandon makes are often distinction...
