JSONView 0.3

JSONView 0.3 is now available at addons.mozilla.org. This fixes an error that was showing up when really large JSON files were being displayed, and adds a feature that displays empty arrays and object on one line instead of on two (and doesn’t display the expand/collapse button for them). I also put in some preliminary support for JSONP, based on a patch submitted by Gabriel Barros. The catch is that it only works with content served with the “application/json” MIME type, which is actually not the correct MIME type for JSONP – it should be “text/javascript” or another JavaScript type. Unfortunately I haven’t been able to figure out how to get Firefox to let me handle “text/javascript” the way I do with “application/json” – it seems to be special-cased or something. If any Firefox gurus are reading and know a solution, please let me know! I was holding onto this release for a while hoping to fix that, but I decided that releasing something was better than nothing, so it’s out there and you can play with it. You can see an example JSONP response with the callback highlighted here. I did notice a bug with the 0.3 release right after it was approved – if a value is 0 or false, it shows up as blank. I’ll have that bug fixed with the next release, which should be very soon. It’s great to see that JSONView has become so popular, with over 50,000 downloads and about 12,000 regular users.

XBList 3.2.4

Halo 3: ODST was released a couple weeks ago, and Bungie redesigned their site a bit to include ODST info in your Service Record. This included changing the pages just enough that XBList got confused trying to figure out emblems for people who had never played Halo, and started showing the wrong emblems for those people (only if you prefer Halo emblems to Xbox emblems, which isn’t the default). Not a huge bug, but I took the opportunity to clean up a bunch of stuff in XBList and put out a little release. In addition to the Halo emblem fix, I fixed a bug where your settings could get corrupted and you wouldn’t be able to start XBList. I also cleaned up the menus and settings, consolidating the Halo links into one item, and removing the option to choose a custom notification sound or turn off debug logging. The debug log is much easier to get to if you’re having trouble – previously I had people dig through their Application Data folders for the log, but now there’s an item in the Help menu that opens the debug log directly. Paired with some much more detailed logging, I should be able to fix future problems much more easily. I also changed the system tray icon to bring XBList to the front on a single click rather than a double click, since that feels much more natural in Windows 7. Lastly (and probably not too importantly for most people), I’m storing emblems in your local Windows profile now, instead of the roaming profile. For the few people who use XBList and have roaming profiles enabled, this should save you some sync time. Anyway, you should have been prompted to update when I pushed the update two weeks ago, but if you haven’t gotten it yet you should download and install it now. I still have plans for a major overhaul of XBList, but it’s low on my list of priorities – XBList is still pretty popular, but not as much as it used to be, with maybe 5,000 active users.

TopProcess 1.4

This last update has been a long time coming. Ever since I installed Internet Explorer 8, the TopProcess sidebar gadget has been randomly crashing. I’m not sure what changed in Internet Explorer to make it screw up every so often, but it does. However, it only crashes after running for a few days, so for months I’ve been tweaking the code a bit, then waiting until it crashes, then tweaking some more, rinse, repeat. I’ve finally nailed it down to the point where crashes are very rare, and then I added some code that automatically resets the gadget when it crashes. So you should never see it mess up again. There is also a gadget log file in the gadget’s install directory that I’m using to store errors, so it should be easier to troubleshoot in the future. Lastly, Jean-Pierre van Riel contributed a patch that added IO tracking to TopProcess, so there is now a third way to view your processes. This view shows you the total IO usage (combined bytes in and out, per second) which seems to cover both disk and network access. Get the update from me or from Windows Live Gallery and be sure to rate the gadget. I’m excited to see that it’s been downloaded over 100,000 times from WLG (plus who knows how many downloads from my site).

I’ve still got a partial rewrite of XBList sitting on a back burner that should fix the intermittent crashes some people have been reporting, as well as drop the “sign in with Internet Explorer” requirement and generally make logging in more reliable. However, I’ve got a lot of other projects going, and XBList doesn’t crash for me, so it might be a while until it’s out. Until then, enjoy XBList 3.2.2 and the new Xbox.com!

Update: I was a bit too hasty, and 3.2.2 had a bug that prevented it from loading your Xbox Live messages. I’ve uploaded 3.2.3 that fixes that.

I do a lot of these challenges, so I wanted to be able to keep track of their progress on my sidebar. The gadget shows you the time left in the challenge, the current standings, and the “live score”, which is the gamerscore each player has earned that day that hasn’t been counted in the official standings yet (gamerscore is sampled by 360Voice.com at midnight PST each day). Once the challenge is over, the winner is given a little crown and the gadget waits for the next challenge.

Fortunately, the 360Voice.com developers had the good sense to provide an XML web services API to their challenge data (and a lot of other stuff too!) so it’s not too hard to make cool things like this gadget that tie into their site. For this project I went ahead and included my favorite JavaScript library, jQuery, and a neat jQuery-based databinding library called chain.js. Using these made development a lot smoother – the old familiar Sidebar bugs and Internet Explorer weirdness was still there, but overall it wasn’t too bad. I’ve specifically designed it to be as light as possible on 360Voice.com’s API too, so hopefully it won’t impact their service.

I think this is the most attractive gadget I’ve made – it’s certainly the most data-rich. I’m really proud of how it came out. I hope everybody enjoys it, and if you haven’t ever done a 360Voice challenge, go start one! Also, if you like it, please rate it at Windows Live Gallery.

P.S.: While I was monkeying around with gadgets, I’ve made some minor changes to my Top Process gadget – the text-fade option is no longer there since it really didn’t add anything, and I may have fixed a couple minor bugs.

When it’s floating, you can choose either form of the Bungie Card. It’s a little weirder when it’s docked to the sidebar. First, it scales down to fit the sidebar. Then, to see the wide version, you just click on the gadget and the wide card shows up in a flyout. It’s a nice way to keep track of things without taking up too much space. As a bonus, double-clicking on either form will take you to your Halo 3 stats page.

Like the other gadgets I’ve done, this was much more difficult to develop than it should have been. The hardest part was getting the scaled-down card for when the sidebar is docked. At first I just zoomed out the page, like I had done for my Xbox Live Gamercard gadget, but it looked absolutely awful. With the exception of newer browsers like Firefox 3 and Safari, “resizing” an image by just changing the HTML element’s dimensions has always used nearest-neighbor filtering, resulting in a truly horrid image. My first instinct was to try and use the MS-proprietary “filter” CSS property to apply a Matrix DXImageTransform that would do the scaling, since that transform has an argument that’ll get it to use bilinear filtering, which is at least decent. However, Sidebar seems to think that that is a dangerous “active content” operation and blocks it. I tweaked it around for a while before stumbling on a workaround – the BasicImage filter was not blocked, and if I applied any transform at all, the basic zoom scaling would filter the image in a more pleasant way. So right now I’m using an opacity filter set to make the image completely opaque. It’s silly, but it works, and I guess this is what I should expect at this point. Trust me, you wouldn’t have liked it before – the image on the left is the way it looks now, the image on the right is with the original smoothing method:

I actually have another Xbox-related Sidebar gadget in development which is more complex but of limited interest. I hope everyone enjoys the Bungie Card gadget – feel free to send me feedback directly, and please rate the gadget at Windows Live Gallery.
