Currently, only local Win32/Unix and in memory FS are supported but interfaces are clean enought to be a good starting point to more FS (Zip, ftp, WedDav, GDrive/DropBox/SkyDrive).
Until 4.5 version, .Net restricts System.Array’s size to 2 Gb (like any single object) even in 64 bits environment.
Since .Net 4.5, a config entry can be used in 64 bits to permit greater size:
<configuration> <runtime> <gcAllowVeryLargeObjects enabled="true" /> </runtime> </configuration>
but Microsoft’s System.Array have index limited to Int32.MaxValue: 2147483647 (Mono can be use with configuration option –enable-big-arrays to use Int64 capacity – see here).
Another alternative can be to use it’s own big array like this one BigArray, getting around the 2GB array size limit – SpankyJ – Site Home – MSDN Blogs.
Set ToolTipService.ShowOnDisabled property to true.
An interesting analysis of performances of Asm.js generated by Emscripten versus C native code.
Pros: Asm.js can be really fast on optimized browser (currenltly only Firefox 22).
I’ve made my personnal very small test using The Lua VM, on the Web (higher is better):
- Firefox 22: 430
- IE 10: 133
- Chrome 28: 128
Even if Mozilla have made a great job on its Firefox 22 Asm.js optimizations, Asm.js future depends on its ability to convince either IE or Chrome to join their forces in Asm.js direction.
More details here: Surprise! Mozilla can produce near-native performance on the Web | Ars Technica.
Free weather maps and REST API in json/xml (OpenWeatherMap – actual and forecast weather).
A persistent asynchrounious dictionary of blob indexed by string. Usefull to implement cache of JSON.Net, HTTP Requests, Images or User credential (a BlobCache.Secure can be used for encrypted store). SQLite3 can(/should) be used for better reliable and concurency capacities.
And, of course, available as Portable Class Library (PCL): github/Akavache.
ReactiveUI brings MVVM to a new level with a simple binding model combining RX to Xaml. Property changes, commands, .Net eventsend of asynchronious actions becomes observable and can be combined together.
And version 5.0 is provided as Portable Class Library for:
- .NET 4.0/4.5 (WPF)
- Windows Phone 8
- Windows Store Apps (WinRT)
Great. Perhaps the next thing to try in a real project.
With the emscripten’s ability to generate asm.js (-s ASM_JS=1 details here) and recent advances in asm.js browser native support (Firefox 22+ and perhaps clue of Google interest), this way to port legacy code can be the next big thing.
