I was bit by a 2.6 year old Fox(Pro)

Talk about old ghosts coming back to haunt you.

I was upgrading a customer's old Foxfire! installation from version 3.0 to 8.0. They were running Foxfire! 3.0 under FoxPro 2.6/Windows.

But they had this one report that kept on crashing under the 8.0 version that would run fine under their old version.

I tried to run Foxfire! 3.0 under a copy of Visual FoxPro and it crashed there as well.

Hmmm...what could it be? I looked at the SQL generated.

There was the problem that was causing the crash: one of the relationships was referring to a field that didn't even exist.

The field in the SQL referred to a field named PART_SEC_ID_I but the real field was called PART_SEC_I.

But why didn't it crash under the older version?

The reason? FoxPro 2.6 ignored the extra fields.

I opened up the table in FoxPro 2.6.

? part_sec_i
** returned a value
? part_sec_id_i
** returned the same value.

Sheesh...I can't believe we were actually able to build quality applications back then but then again, when our tool wouldn't even tell us we were wrong in our field names - who needed field validation?

Now the fun part - how to tell someone that even though their old application worked great, it was actually not reporting a problem it should have been.

Well, that explains CodePlex...

In a move that will be sure to anger open source (or rather anti-paid software, anti-Microsoft open source)  zealots, Microsoft is planning to buy GitHub.

A year ago, I mused about why Microsoft would shut down CodePlex and how the world needs competing source code repositories to be strong. I'm not the only one per this Slashdot article :
"...people have warned about GitHub becoming as large as it did as problematic because it concentrates too much of the power to make or break the open source world in a single entity, moreso because there were valid questions about GitHubs financial viability...." - Jacques Mattheij

I will be interested in seeing this play out - whether developers jump ship or not. Have all the efforts Microsoft has made in pushing towards open source be seen as genuine or will all the zealots jump ship or maybe even attack?

Microsoft's comment about why they shut down CodePlex referred to how spammers were using CodePlex. Well, GitHub has its own …

Attending Southwest Fox 2019 could change your life - Find out how

Southwest Fox is coming up in October and as I do every year, I spoke with the organizers Rick, Doug and Tamar on the FoxShow.

Deadlines for Southwest Fox:
Super-saver price (before July 1): $695
Early-bird price (before August 1): $770
Regular price (August 1 and later): $820
This year, I took a different approach with separate shows for each organizer but the main message is still the same : July 1st is their Go/No-Go date.

Conferences don't talk about this very often. I don't think developers really question if Apple will hold their WWDC in June or Microsoft will hold their Build conference - but that's because those conferences are vendor-led.

Southwest Fox is a community-driven conference - it's not driven by a company with an agenda. Listen to the interviews and you can hear how important each of the organizers feel the live connection between speakers and among attendees.

FoxInCloud Stats

FoxInCloud sent this link a while back about their statistics regarding visits to their site:

What's interesting here is the breakdown of people. Yes, I think it's understandable that the Fox community is getting older.

Another factor is the growth of the mobile and web environments taking over development. These environments really do push people towards the newer non-SQL or free SQL/hosted environments but more towards hosted storage options like Amazon and Google. A tool like FoxInCloud that helps MOVE existing applications to the cloud inherently competes with those environments.

But FoxInCloud also allows developers to extend their application further by giving them a starting point using Javascript and the basic CSS (such as Bootstrap). If you're not rebuilding your application from scratch, it's certainly a great step forward.
