Note
that like using WinRT in .NET, you use the System.Uri .NET class instead of the Windows.Foundation.Uri WinRT class which is not projected and under the covers the system will convert the System.Uri
to a Windows.Foundation.Uri.
You can use conditional breakpoints and debugging commands in windbg and cdb that together can amount to effectively patching a binary at runtime. This can be useful if you have symbols but you
can't easily rebuild the binary. Or if the patch is small and the binary requires a great deal of time to rebuild.
Skipping code
If you want to skip a chunk of code you can set a breakpoint at the start address of the code to skip and set the breakpoint's command to change the instruction pointer register to point to the
address at the end of the code to skip and go. Voila you're skipping over that code now. For example:
bp 0x6dd6879b "r @eip=0x6dd687c3 ; g"
Changing parameters
You may want to modify parameters or variables and this is simple of course. In the following example a conditional breakpoint ANDs out a bit from dwFlags. Now when we run its as if no one is
passing in that flag.
bp wiwi!RelativeCrack "?? dwFlags &= 0xFDFFFFFF;g"
Slightly more difficult is to modify string values. If the new string length is the same size or smaller than the previous, you may be able to modify the string value in place. But if the string
is longer or the string memory isn't writable, you'll need a new chunk of memory into which to write your new string. You can use .dvalloc to allocate some memory and ezu to write a string into
the newly allocated memory. In the following example I then overwrite the register containing the parameter I want to modify:
.dvalloc 100 ezu 000002a9`d4eb0000 "mfcore.dll" r rcx = 000002a9`d4eb0000
Calling functions
You can also use .call to actually make new calls to methods or functions. Read more about that on the Old New Thing: Stupid debugger tricks: Calling functions and methods. Again, all of this can be used in a breakpoint command to
effectively patch a binary.
This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration
space missions, like a trip to an asteroid or even to Mars.
The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But
unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to
internet. So no checking social media kids!
The only people they will talk with regularly are mission control and each other.
The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection.
What will they be doing?
Because this mission simulates a 715-day journey to a Near-Earth asteroid, the four crew members will complete activities similar to what would happen during an outbound transit, on location at
the asteroid, and the return transit phases of a mission (just in a bit of an accelerated timeframe). This simulation means that even when communicating with mission control, there will be a
delay on all communications ranging from 1 to 10 minutes each way. The crew will also perform virtual spacewalk missions once they reach their destination, where they will inspect the asteroid
and collect samples from it.
A few other details:
The crew follows a timeline that is similar to one used for the ISS crew.
They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercises.
They will be growing and taking care of plants and brine shrimp, which they will analyze and document.
But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario
simulations, including one that will require them to maneuver through a debris field during the Earth-bound phase of the mission.
Throughout the mission, researchers will gather information about cohabitation, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous
devices that each capture different types of data.
Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were
working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.
Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.
In total, this mission will include 19 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for
future missions.

Chakra, the JavaScript engine powering the Edge browser and JavaScript Windows Store apps, does the work to project WinRT into JavaScript. It is responsible for, among other things, converting
back and forth between JavaScript types and WinRT types. Some basics are intuitive, like a JavaScript string is converted back and forth with WinRT’s string representation. For other basic types
check out the MSDN links at the top of the page. For structs, interface instances, class instances, and objects things are more complicated.
A struct, class instance, or interface instance in WinRT is projected into JavaScript as a JavaScript object with corresponding property names and values. This JavaScript object representation of
a WinRT type can be passed into other WinRT APIs that take the same underlying type as a parameter. This JavaScript object is special in that Chakra keeps a reference to the underlying WinRT
object and so it can be reused with other WinRT APIs.
However, if you start with plain JavaScript objects and want to interact with WinRT APIs that take non-basic WinRT types, your options are less plentiful. You can use a plain JavaScript object as
a WinRT struct, so long as the property names on the JavaScript object match the WinRT struct’s. Chakra will implicitly create an instance of the WinRT struct for you when you call a WinRT method
that takes that WinRT struct as a parameter and fill in the WinRT struct’s values with the values from the corresponding properties on your JavaScript object.
// C# WinRT component public struct ExampleStruct { public string String; public int Int; }
public sealed class ExampleStructContainer { ExampleStruct value; public void Set(ExampleStruct value) { this.value = value; }
public ExampleStruct Get() { return this.value; } }
You cannot have a plain JavaScript object and use it as a WinRT class instance or WinRT interface instance. Chakra does not provide such a conversion even with ES6 classes.
You cannot take a JavaScript object with arbitrary property names that are unknown at compile time and don’t correspond to a specific WinRT struct and pass that into a WinRT method. If you need
to do this, you have to write additional JavaScript code to explicitly convert your arbitrary JavaScript object into an array of property name and value pairs or something else that could be
represented in WinRT.
However, the other direction you can do. An instance of a Windows.Foundation.Collections.IPropertySet implementation in WinRT is projected into JavaScript as a JavaScript object with property
names and values corresponding to the key and value pairs in the IPropertySet. In this way you can project a WinRT object as a JavaScript object with arbitrary property names and types. But
again, the reverse is not possible. Chakra will not convert an arbitrary JavaScript object into an IPropertySet.
// C# WinRT component public sealed class PropertySetContainer { private Windows.Foundation.Collections.IPropertySet otherValue = null;
public Windows.Foundation.Collections.IPropertySet other { get { return otherValue; } set { otherValue = value; } } }
public sealed class PropertySet : Windows.Foundation.Collections.IPropertySet { private IDictionary map = new Dictionary();
public PropertySet() { map.Add("abc", "def"); map.Add("ghi", "jkl"); map.Add("mno", "pqr"); } // ... rest of PropertySet implementation is simple wrapper around the map member.
// JS code var propertySet = new ExampleWinRTComponent.ExampleNamespace.PropertySet(); console.log("propertySet: " + JSON.stringify(propertySet)); // propertySet: {"abc":"def","ghi":"jkl","mno":"pqr"}
var propertySetContainer = new ExampleWinRTComponent.ExampleNamespace.PropertySetContainer(); propertySetContainer.other = propertySet; console.log("propertySetContainer.other: " + JSON.stringify(propertySetContainer.other)); // propertySetContainer.other: {"abc":"def","ghi":"jkl","mno":"pqr"}
There’s also no way to implicitly convert a DOM object into a WinRT type. If you want to write third party WinRT code that interacts with the DOM, you must do so indirectly and explicitly in
JavaScript code that is interacting with your third party WinRT. You’ll have to extract the information you want from your DOM objects to pass into WinRT methods and similarly have to pass
messages out from WinRT that say what actions the JavaScript should perform on the DOM.
“This is the chronicle of the most epic retaliation and how I pranked my roommate with targeted Facebook Ads to the point of complete paranoia and delusion.”
Funny anecdote but also a how-to on creating a Facebook ad campaign that targets a single person.
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.
