FRC Spyder 2014?

[pyroslev]

I was at the FTC East Super Regional Last weekend. And I think about 100 people downloaded the app after I showed it to them. You could always tell when a score notification came in cause of someone's reaction.

I just refreshed the app, and I have rankings from the PNW Championship. Android 4.0.

Thank you for the app!

Until the number of matches is >= number of teams, the OPR system of equations is underdetermined.

Consider the equation a + b = 3, there are an infinite number of solutions. The same thing occurs when there are less matches then teams. Since there are 6 teams per match, opr is underdetermined until everyone has 6 matches.

At the championship, it will take until the middle of Friday before OPR is overdetermined.

FRC Tracker won't calculate OPR until the solution is overdetermined. Users of FRC Spyder and any other live OPR updating tool should definitely take OPR with a huge grain of salt until the solution is overdetermined.

Following up, since I was one of those for whom the update wasn't fetching data on Thursday: no problems updating from PNW championship on Friday.

We'll consider more features for next year, but we're currently too busy with paying jobs to add anything else this year.

Hi, Mike,

If there are any interests, I can volunteer to work with the 610 programmers to port it to BlackBerry BB10 for the community. A little giveback to FIRST and the Canadian smartphone pioneer. BB10 can run many Android apps with a simple wrapper.

Billy.

Isn't it half the number of teams? Correct me if I'm wrong, but doesn't each match have two equations, one for each alliance's score?

Is anyone having issues with Spyder on Newton? Not all teams are showing up. It was working earlier today.

Yeah, me too. But the field isnt showing rankings either on matches. I think they had to reset everything and when a team plays now, they are being re-added into the rankings. Just give it a few more matches and everyone should be back.

It's fixed now. They updated it during lunch. FMS wasn't updating properly.

As a preemptive warning, FIRST's data feeds are broken and this is why FRC Spyder isn't updating. Someone at FIRST appears to be editing their result HTML pages using Microsoft Word (!) and this produces a different HTML structure than their normal pages. Since FIRST does not provide the data in a clean API format, we're forced to scrape the data from their result pages and parse it. When they publish data using Microsoft Word, Word changes the layout of the HTML which makes it incompatible with our data parsers.

Unfortunately we are extremely busy supporting the VEX Robotics World Championship and don't have time to tweak our data parsers to deal with the changes FIRST has made.

Maybe someday FIRST will get this right and provide the data in a way more suited for app consumption.

I second the post above. It is very frustrating that FIRST doesn't provide better tools for these third party sites like The Blue Alliance and At The Control. Obviously they want these sites to exist!
