Phil 3.26.15

8:00 – 4:00 SR

  • Tested threejs on target browsers. The hardware acceleration is iffy, but the software renderer and the raytracer work fine
  • Deployed Dong’s FR fixes
  • Working on splitting the chart elements into their own module.
  • Argh! Fat arrow functions can’t inherit in TypeScript! Thinking about making a mapping table? Something like
    • fooPtr = (var:number):void =>{…};
    • fooFn(var:number):void{fooPtr(var);}
    • ????
  • Set up and implemented an interface for calculating behaviors, which works nicely:
  • public behavior = (dClock:number, elapsed:number):void => {
   var rb = this.wglCanvas;
   var ci:IChartElement;
   var i:number = 0;
   if (rb) {
      rb.dprint("Hello controller - sin(elapsed) = " + Math.sin(elapsed).toFixed(2));
      for (i = 0; i < this.chartElements.length; i++) {
         ci = this.chartElements[i];
         ci.setZOffset(Math.sin(elapsed + i));
         ci.behavior(dClock, elapsed);
      }
   }
};

  • modified POC processing so that it cannot be edited/deleted if used in others.
  • tried to update Angular to latest (1.3.15 or 1.4), didn’t work with min attribute in Obligations/Outlays…..
  • fixed incorrect Funding Amount (Number.MAX_VALUE) showing in Obligations/Outlays
  • working on setting central login page….

  • Set up Mark’s accounts
  • Set up an admin account for our tester. Not sure if that’s actually needed?
  • Brought over the latest and greatest for Bill to scan. Should be ready for testing tomorrow.
  • Finish integrating Chartinfo class into testbed. Done, but more of an adventure than I was expecting. First, my development box began acting weird (fan noises, flickering graphics, slow performance). Then it BSOD’d. When I finally got it back up, the debugger kept on getting confused about comments. Once that was sorted, I couldn’t get picking to work on area charts, even though it worked fine for everything else. That traced back to a null value for the component name, which is an explicit test I run to manage tooltips. So once the name from the ChartInfo item was loaded into the glComponent, everything began working correctly. Sheesh.
  • Tried to get my laptop again and also a replacement workstation, since this one is now suspect.
  • Running CC

  • reworking on POC processing
    • server returns list of POCs on add
    • fixed Error not showing on Save/Edit/Delete
    • added instruction
    • set all the modals (pop-ups) to use backdrop: ‘static’ so background is grayed out and must click Ok/Cancel to dismiss

  • Lenny’s out for the week. Going to coordinate with Don and Mike(?) for the time being.
  • Need to set up cluster and stacked barcharts. I think it’s mostly a size and offset issue, so there need to be multiple arrays. Since area charts and bar charts pretty much use the same raw data, I think I’ll make a data object that contains the needed data. That can be set by a server call and passed in regardless of the chart type. Cluster bar charts are just offset by the index times the width. The width in turn is the spacing divided by the number of columns and clusters.
  • It strikes me that if we have enough problems having hardware rendering, that we can use raytracing. Either in the server (povray), or using the threejs raytracer. There is no THREE.RaytracingRenderer in definitelyTyped though.
  • Found a bug while making sure that the software rendering looks ok (it does). Fixed. The OrbitControls were resetting the camera origin. I just needed to not set OrbitControls if the scene is not dynamic.
  • Added ChartInfo class that stores all the numbers for a bar chart or area chart. Compiles, will test tomorrow.
  • Burned a disk containing the newest threejs for Bill.

Phil 3.23.15

8:00 – 10:00, 12:00- 5:00 SR

  • Snow flurries are predicted for tomorrow. Some start to spring, huh?
  • Deployed new FR. All seems to be working.
  • Pinged our potential new servers. They respond in half the time and are farther away. I mean like Georgia, I think.
  • Adding bar charts. Once that works, I’ll try to figure out where all the code should go. I also need to talk to Dong about hooking up to a data source.
  • Bar charts are in and working. Need to set them up for ortho2 rendering.

  • continue working on FR
    • added calculate functions to the download template
    • download works on Chrome, partially on Firefox
    • only a page is downloaded
    • tried various data attribute….. found this is the way!
    • pom.setAttribute('href', 'data:text/attachment,' + encodeURIComponent(content.innerHTML));

  • Still working on the lab problem. I’m using the roll of a six-sided dice to represent labs. Here’s the issue.
    • For an even distribution over a set of options, the probability of an event converges nicely: EvenDistribution
    • A random distribution converges, but not so nicely: RandomDistribution
    • Loaded dice also converge, but in a different way: LoadedDice
    • The question is, how do I tell that the difference between 1 and 2 is acceptable, but that the difference between 2 and 3 isn’t? Also very important is how many “rolls” do you need before you can say that the dice is loaded one way or another? I was looking at Chi Squares, but that doesn’t seem to be right. Currently looking at Binomial Distributions.
    • Ok, it looks like Binomial Distributions are what we want. Here’s what it looks like:BinomialTail
    • In the chart, probabilities accumulate for the first 100 rolls, and then a cumulative binomial distribution is calculated where at least one success happens in the next ten trials. The excel function that does this is:
      • =1-BINOM.DIST(<successes-1>,<trial number starting at 2>, <calculated probability>, TRUE)
    • Note that the probability of a future even sums to more than 100%. This is because the probability of one face coming up at least once in the next ten trials is pretty independent of the other faces, so they get added together. That being said, the differences between the likelihoods remains consistent until they go asymptotic at 100%. This is a pretty good indicator of how far out in the future a prediction can be made. In this case, it looks like 5-15 trials in the future before the high values converge. Note though that the very low values (F5 and F6,which were near zero) still do not have a significant impact on the outcome in this time horizon. So the ability to project into the future is strongly dependent on how spread out the initial probabilities are when the binomial calculations are invoked.

Phil 3.19.15

8:00 – 4:30 SR

  • Worked out a way to calculate the liklihood that a lab will be able to spend it’s money based on past performance. I think it can also be primed with an arbitrary distribution. Need to think about that.
  • Area Charts
    • Added an option to render fastest, which may be needed for Canvas Rendering. Transparency works in SW, which is nice.
    • Adding a method to add to or set the z offset.
    • Added gridlines. Getting close to tying all the pieces together.

  • working on FR
    • added Contract Funded Amount to server codes
    • tried to use $watch for summing the Funded Amount – not quite working. Does $watch check for reference instead of values?
    • HTML generation for export and saving it as MSWORD works!
    • Chrome just saves file where Firefox asks to Save or Open… Is it my browser settings?
    • reworking template

Phil 3.18.15

8:00 – 4:00 SR

  • No problems with the new FR. Testing to begin Friday?
  • Need to look into JIT manufacturing process control as possible way of managing labs
  • The current goal is to see how trustworthy labs are WRT spending their funds to target. It turns out, I have an equation for that 🙂
  • Added behavior callback to CanvasClasses and ComponentClasses. It also seems to have fixed my weird ts error in Webstorm.
    • Tested and working.
  • Adding tooltip data points to track the top line of the chart, including when the chart is animating. – done

Progress for today:

  • working on FR Export…
    • created a directive and templates to generate HTML using $compile service
    • controller in the directive doesn’t work quite right.
  • another field for Contract Details – Contract Funded Amount
    • modified client codes
    • added contract_funded_amount to fr_contract_details table – db_updates.sql
      • ALTER TABLE `fr_contract_details` ADD `contract_funded_amount` DECIMAL(10,2) NULL AFTER `funding_request_id`;
    • working on server codes
