In Win8.1 JavaScript UWP apps we supported multiple windows using MSApp DOM APIs. In Win10 we use window.open and window and a new MSApp API getViewId and the previous MSApp APIs are gone:
| Win10 | Win8.1 | |
|---|---|---|
| Create new window | window.open | MSApp.createNewView |
| New window object | window | MSAppView |
| viewId | MSApp.getViewId(window) | MSAppView.viewId |
We use window.open and window for creating new windows, but then to interact with WinRT APIs we add the MSApp.getViewId API. It takes a window object as a parameter and returns a viewId number that can be used with the various Windows.UI.ViewManagement.ApplicationViewSwitcher APIs.
Views in WinRT normally start hidden and the end developer uses something like TryShowAsStandaloneAsync
to display the view once it is fully prepared. In the web world, window.open shows a window immediately and the end user can watch as content is loaded and rendered. To have your new windows act
like views in WinRT and not display immediately we have added a window.open option. For example
let newWindow = window.open("https://example.com", null, "msHideView=yes");
The primary window that is initially opened by the OS acts differently than the secondary windows that it opens:
| Primary | Secondary | |
|---|---|---|
| window.open | Allowed | Disallowed |
| window.close | Close app | Close window |
| Navigation restrictions | ACUR only | No restrictions |
The restriction on secondary windows such that they cannot open secondary windows could change in the future depending on feedback.
Lastly, there is a very difficult technical issue preventing us from properly supporting synchronous, same-origin, cross-window, script calls. That is, when you open a window that's same origin, script in one window is allowed to directly call functions in the other window and some of these calls will fail. postMessage calls work just fine and is the recommended way to do things if that's possible for you. Otherwise we continue to work on improving this.
On whistleblower Edward Scissorhands: "to cast him out… simply because he has scissors

From Inside Edward Snowden’s Life as a Robot:
Wizner had to jump on a phone call during a meeting with his whistleblower client. When he got off the phone, he found that Snowden had rolled the bot into civil liberties lawyer Jameel Jaffer’s office and was discussing the 702 provision of the Foreign Intelligence Surveillance Act. “It was kind of cool,” Wizner says.
It is neat but they’re marketing video is at times strangely terrifying. Put different music on when the Susan-bot comes up behind the unknowing Mark and this could be a horror movie trailer.
More than 90% of Americans believe that the US government is unduly influenced by money, and the Mayday.US super PAC is raising $5M to fund the election campaigns of politicians who’ll pledge to dismantle super PACs and enact other campaign finance reforms. They raised more than $1M in 30 days last month, and this month, the goal is $5M. It’s the brainchild of Lawrence Lessig, who’s going to run prototype the project by running five electoral campaigns in 2014, and use the lessons of those projects to win enough anti-corruption seats in 2016 to effect real change.
Again, I’m not able to contribute to Mayday.US, because I’m a Canadian and Briton. But I ask my American friends to put in $10, and promise that I’ll put CAD1000 into any comparable Canadian effort and/or £1000 into a comparable UK effort. We all win when countries embrace evidence-based policy guided by doing what’s best for its citizens, rather than lining the pockets of corrupting multinationals.

My second completed app for the Windows Store was Words with Hints a companion to Words with Friends or other Scrabble like games that gives you *ahem* hints. You provide your tiles and optionally letters placed in a line on the board and Words with Hints gives you word options.
I wrote this the first time by building a regular expression to check against my dictionary of words which made for a slow app on the Surface. In subsequent release of the app I now spawn four web workers (one for each of the Surface's cores) each with its own fourth of my dictionary. Each fourth of the dictionary is a trie which makes it easy for me to discard whole chunks of possible combinations of Scrabble letters as I walk the tree of possibilities.
The dictionaries are large and takes a noticeable amount of time to load on the Surface. The best performing mechanism I found to load them is as JavaScript source files that simply define their portion of the dictionary on the global object and synchronously (only on the worker so not blocking the UI thread). Putting them into .js files means they take advantage of bytecode caching making them load faster. However because the data is mostly strings and not code there is a dramatic size increase when the app is installed. The total size of the four dictionary .js files is about 44Mb. The bytecode cache for the dictionary files is about double that 88Mb meaning the dictionary plus the bytecode cache is 132Mb.
To handle the bother of postMessage communication and web workers this was the first app in which I used my promise MessagePort project which I'll discuss more in the future.
This is the first app in which I used the Microsoft Ad SDK. It was difficult to find the install for the SDK and difficult to use their website, but once setup, the Ad SDK was easy to import into VS and easy to use in my app.
“Jon Hamm And Adam Scott’s ‘greatest Event In Tv
History’ Was A Tribute To A Forgotten ’80s Classic
If you know more about Simon and Simon than its intro and general premise, you’re better at TV than I am. If you’ve never heard of Simon and Simon, you’re the BEST at TV because, honestly, Simon
& Simon — a CBS series about two mismatched brothers who ran a private detective service; it ran for eight seasons — wasn’t good.

PPACA (aka Obamacare) broken down into its main subsections with brief explinations and citations linking into the actual PPACA document (why is it always PDF?).
Its interesting to see the very small number of parts folks are complaining about versus the rest which mostly strikes me as “how could this not already be the case?”
I’m no expert, and everything I posted here I attribute mostly to Wikipedia or the actual bill itself, with an occasional Google search to clarify stuff. I am absolutely not a difinitive source or expert. I was just trying to simplify things as best I can without dumbing them down. I’m glad that many of you found this helpful.”
Breakdown of the STL’s implementation of next_permutation. Ever wondered how that works?
By the URI RFC there is only one way to represent a particular IPv4 address in the host of a URI. This is the standard dotted decimal notation of four bytes in decimal with no leading zeroes delimited by periods. And no leading zeros are allowed which means there's only one textual representation of a particular IPv4 address.
However as discussed in the URI RFC, there are other forms of IPv4 addresses that although not officially allowed are generally accepted. Many implementations used inet_aton to parse the address from the URI which accepts more than just dotted decimal. Instead of dotted decimal, each dot delimited part can be in decimal, octal (if preceded by a '0') or hex (if preceded by '0x' or '0X'). And that's each section individually - they don't have to match. And there need not be 4 parts: there can be between 1 and 4 (inclusive). In case of less than 4, the last part in the string represents all of the left over bytes, not just one.
For example the following are all equivalent:
The bread and butter of URI related security issues is when one part of the system disagrees with another about the interpretation of the URI. So this non-standard, non-normal form syntax has been been a great source of security issues in the past. Its mostly well known now (CreateUri normalizes these non-normal forms to dotted decimal), but occasionally a good tool for bypassing naive URI blocking systems.
Sarah and I have been enjoying Glitch for a while now. Reviews are usually positive although occasionally biting (but mostly accurate).
I enjoy Glitch as a game of exploration: exploring the game's lands with hidden and secret rooms, and exploring the games skills and game mechanics. The issue with my enjoyment coming from exploration is that after I've explored all streets and learned all skills I've got nothing left to do. But I've found that even after that I can have fun writing client side JavaScript against Glitch's web APIs making tools (I work on the Glitch Helperator) for use in Glitch. And on a semi-regular basis they add new features reviving my interest in the game itself.
I had previously replaced my use of Delicious with Google Reader. Delicious had a number of issues during their switch over from Yahoo to the new owners and I was eventually fed up enough to remove it from daily use. I used Delicious to do the following things:
Of course I wrote this and switched over about 1 week before Google removed the sharing feature from Google Reader. I'm irritated but in practice it forced me to find a different option which has worked out mostly better. New blog post coming soon about that...
Irritatingly, my G1 won't show me PDFs so I've made the Google Docs PDF viewer which will load PDFs on the web up in Google Docs. Google Docs has the useful ability to display PDFs in web browsers without any Adobe software and works (mostly) on Android.
This was very easy to put together as an Android activity. First its necessary to register the application as handling PDFs from the web. This is done via the intent-filter declaration in the manifest:
intent-filter
action android:name="android.intent.action.VIEW"/
data android:scheme="http" android:mimeType="application/pdf"/
category android:name="android.intent.category.DEFAULT"/
category android:name="android.intent.category.BROWSABLE"/
/intent-filterSecond, the activity opens up the browser to Google Docs pointing to the PDF.
Intent intent = new Intent();
intent.setAction(getIntent().getAction());
intent.setData(Uri.parse(
"http://docs.google.com/gview?embedded=true&url=" +
percentEncodeForQuery(getIntent().getData().toString())));
startActivity(intent);
