Finding patterns...

So now that Rick has put up the FoxBlogs tag cloud, some may be asking "what's a tag cloud?"

Basically it's running the content analysis service from Yahoo (who knew they had one? Everytime Google talks about something, everyone's on it but Yahoo? Needs to do better job of marketing to developers- or maybe I should just listen better )

What does that do? Wow - no wonder no one likes to listen to developers ramble on...they talk and talk and talk but don't really say what it does... (this is because I just went through 5 minutes of links without a good "stand on its own" description.)

Essentially, it attempts to put things into context automatically. For example, when Ken Levy talkes about Headphones, , the entire set of threads are tagged with that term. Now how does it recognize that term? That's the trick.

From Yahoo's own Y!Q (context query), "Y!Q analyzes the context you provide and determines automagically the most important keywords to use." - so you can provide the context but it determines the keywords.

Uh - "automagically?"

In short, it must look for patterns. Patterns are really quite interesting. I'm just starting to read as opposed to listen, to Freakonomics by Steven Levitt and Stephen Drubner.

(it was on my Audible wish list but I ended up getting the hard copy version)

In one chapter, they describe how they identified that some teachers in the Chicago Public System were cheating on standardized tests (yes, teachers, not students - read the book - very cool chapter on why a teacher would be motivated to cheat) - and they did it through patterns ( teachers "fixed" certain exams with the correct answers in a "pattern").

Now patterns aren't necessarily keywords but it would be very cool to take the TagCloud data at the end of, say, a year, and see if there are any patterns in the way people blog - kind of like a VFP ZeitGeist

I love finding patterns in data - it's one of the things I love about using FoxPro interactively. While the TagCloud application doesn't do the analysis automatically, it is very cool the way it highlights keywords that everyone is talking about (obvious ones like Microsoft, vfp and visual foxpro) and ones that have only been mentioned a few times or only on a particular site (like that all important word, "argh!")

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

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.

eero icons - What the heck?

How to change icons used by eero.... Formerly titled: Eero router - Nicknames and icons UPDATE: Finally!!!! The most recent update to the eero now allows you to specify icons from their library. And it's a GOOD library - thank you. Finally! If you've extended your wireless network using eero , you have downloaded the app. I upgraded my network when I noticed a bunch of dead spots in what should have been a fairly reasonable coverage space (1700 sqft home). With two eero devices, our home is pretty well covered. Click on Connected devices and every device connected to your network is displayed. The eero app identifies the manufacturer and, with some devices, even the name of a given device. The eero app may also show an icon that represents its use. Some of the more obvious icons are those for phones, laptops and TVs. Unfortunately, the majority of devices get a fairly generic "wifi" icon. But you can change this. Give devices a nickname using ce
