I've been slogging away at this for ages and can't figure it out. All the other StackOverflow answers are marked as accepted but don't work so I'm sure I'm missing something!
I have a ListView inside a content page, that I simply want to bind to a property of List. The listview appears blank with the binding but DOES appear when I specifically set the ItemsSource after the web API returns its data - however, I want to do it property and bind it.
...ANSWER
Answered 2019-Oct-07 at 06:48If you want the ListView to automatically update as items are added, removed and changed in the underlying list, you'll need to use an ObservableCollection. ObservableCollection is defined in System.Collections.ObjectModel and is just like List, except that it can notify ListView of any changes

QUESTION
I'm pretty new to the Linux device tree, and I am searching for a way to disable the SD Card Interface on my Linux embedded system.
I recently figured out how to disable my USB Interface by unbinding it's device driver, using echo -n 1-0:1.0 > /sys/bus/usb/drivers/hub/unbind
Now I am trying to do the same for the SD Card slot, but I am running into problems finding the correct path/driver to unbind. I believe the device is located in /sys/block/mmcblk1, but I'm not really sure how to go about finding the correct device id/unbind file. Any tips on disabling an SD interface?
Edit 1: Upon further inspection, mmcblk1 doesn't even show up when there is no SD card inserted in the slot. How should I go about disabling the interface itself, not just disabling a single card?
Edit 2: It looks like disabling hotplugging might work, but I am now struggling to understand mdev rules.
Edit 3 (Solution): After slogging through the device tree, I was able to track down the specific device and driver combination that was running my mmc reader. echo -n mmc1:aaaa > /sys/bus/mmc/drivers/mmcblk/unbind is able to unbind the driver from the device (mmc1:aaaa). I also had to tweak my mdev rules, as the driver was reloaded every time I plugged in my device. The final solution was to drop the following into /etc/mdev.conf: mmcblk([1-9]+) root:disk 777 @echo -n mmc1:aaaa > /sys/bus/mmc/drivers/mmcblk/unbind, which runs every time an mmc device binds (excluding mmcblk0, as we are using that elsewhere) and immediately unbinds the driver.
ANSWER
Answered 2018-Apr-16 at 21:40You can try blacklisting /lib/modules/$(uname -r)/kernel/drivers
/mmc/core/mmc_block.ko.xz.
Create the file /etc/modprobe.d/blacklist_sdcard.conf and add the line: "blacklist mmc_block" without the quotes, and then reboot.
Note that this might disable other devices on your system if something else uses it, so you might discover you've created a problem.
edit
Sorry the above didn't work for you. I was also concerned that other things were using the device driver.
This should do it:
Create /etc/udev/rules.d/99-disable-automount.rules
and add the line:
ACTION=="add|change",KERNEL=="sdb",ENV{UDISKS_IGNORE}="1"
using whatever device the card reader mounts as for the "KERNEL==" section.
Then do udevadm control --reload
and you should be all set.
QUESTION
I have a UWP app that includes a webview that shows files compiled from a separate source. The separate source dumps all the files out into a folder, and I want to just include the entire contents of that folder automatically in my UWP build.
I've not found a simple, automatic way to do this.
I can sloggingly add them manually using this method: Copying assets into UWP application package however this doesn't really help me because the process that generates the files in the folder can add, remove or change the names of the files all over the place. Every time it does this (and this can be multiple times a day) I have to go in and re-add or remove the files that have appeared/disappeared.
Currently my best idea is to write a script that will parse the folder, list the files and then automatically generate a vcxproj file from that list. This, however, seems hacky and would have several drawbacks (eg. any changes I make to the project file in VS2015 would get binned unless I also changed the script)
Is there a way to just tell VS2015 to put all the files (and sub-folders) in a named folder into the UWP app, no questions asked?
...ANSWER
Answered 2017-Sep-29 at 08:36It's possible to add a folder and all subfolders and files via a Property Sheet/.props file.
This example includes all files and the folder structure below 'TestItem' in the UWP appx package under 'Assets\Website'. Note that there's no entry for TestItem itself, as that is the root.
QUESTION
I'm working on an algorithm that repeatedly needs the (Euclidean) distance to the k-th closest point from some given query point all taken from a vector of points. Also, I repeatedly need to find all points within a given radius of a point.
I'm thinking of using k-d trees from the nanoflann library. However, the knnSearch() function returns all the k nearest neighbours, which I don't require. (The radiusSearch() function suits me just fine, though).
Is there a more efficient way to get what I need, other than slogging through all the k nearest neighbours every time? A better data structure or a better implementation? (I'm using C++.)
...ANSWER
Answered 2017-Sep-03 at 07:05I'm thinking of using k-d trees
Excellent choice for 2D or 3D.
k-d trees are a good choice for low dimensional data (which I assume you have since nanoflann is "mostly optimized for 2D or 3D point clouds.").
Is there a more efficient way to get what I need, other than slogging through all the k nearest neighbors every time?
You need the k-th Nearest Neighbor (NN), but when searching a k-d tree for k NNs, the costly operation (in terms of time) is finding the first NN (which requires you to descend down the tree, all way from the root to a leaf).
Finding the 2nd, 3rd or another indexed NN is relatively cheap, and I highly doubt that it will harm performance (i.e. that getting the k-th NN out of the k NNs returned by the tree will be the bottleneck).
So, I strongly suggest you not to worry about that step.
A better data structure or a better implementation?
I don't think so. I haven't used nanoflann, but CGAL for this kind of queries, and it worth giving a try (however CGAL requires installing (not a piece of cake), while nanoflann is just a header include).

QUESTION
(Followup code-review question here, with more details of the context of this loop.)
Environment:
- Windows 7 x64
- VS 2017 community
- Targeting x64 code on Intel i7700k (kaby lake)
I don't write a lot of assembler code, and when I do, it's either short enough or simple enough that I don't have to worry much about squeezing the maximum amount of perf out of it. My more complex code is usually written in C and I let the compiler's optimizers worry about latency, code alignment, etc.
However in my current project, MSVC's optimizer does a remarkably poor job on the code in my critical path. So...
I haven't yet found a good tool that does either a static or runtime analysis of x64 assembler code with a view to removing stalls, improving latency, etc. All I've got is the VS profiler which tells me (roughly) which instructions are taking the most time. And the clock on the wall that tells me if the latest change has made things better or worse.
As an alternative, I've been slogging my way thru Agner's docs with the hope of squeezing some more perf out of my code. The problem is that it's hard to understand any of his work until you understand all of it. But pieces of it make sense, and I'm trying to apply what I have learned.
What that in mind, here's the core of my innermost loop which (not surprisingly) is where the VS profiler says my time is being spent:
...ANSWER
Answered 2017-Jul-16 at 11:12A partial answer:
Intel provides a tool named Intel Architecture Code Analyzer (described here) that does static analysis of code, showing (kind of) what ports are in use in a section of asm code.
Unfortunately:
- v2.3 doesn't include the essential (and only) header file. You can find this file in v2.2.
- v2.2 includes the header, but omits a python script (pt.py) for analyzing the output. This file is also not included in v2.3 (haven't found it yet).
- One of the output formats from iaca is a .dot file, that is read by graphviz, but the Intel docs fail to describe which of the 38 executables in graphviz is used to display output.
But perhaps most importantly (for my needs):
- v2.3 (currently the most recent release) supports Skylake, but not Kaby Lake.
Given how the implementation details change between processors, that makes all the output suspect. Dates in the pdf file suggest that v2.3 was released July 2017, meaning that I'm probably going to have to wait a while for the next release.
QUESTION
I've got a situation in C++ where I have a costly sub-problem: nearly a minute. Further, this subproblem--bool f(x)--gets longer as x ranges from [1,n].
On the range of [1,n], there is a point 1 such that f(k), k < j is always false...and f(m), j < m is always true.
I need to find that point.
The way I need to do it is with binary search starting at x=1 (so that it never even touches the time consuming region, where x is close to n).
Right now, I am manually slogging through a binary search implementation where I start at a minimum value for a function (so, f(1), which is false). Then I double the input value until I reach a state where f(x) is happy (true). This part is no big deal. I can do it manually fine.
Next, I want to binary search on the range [x/2,x] for the first value where f(x) = true (noting that f(x/2) must equal false, since f(1) = false...and I need to do it without making any mistakes. And this is where things are getting a little hairy.
So I have a creeping suspicion that C++ has this already implemented, but I am new to C++, and have limited experience with the libraries. I am currently looking at binary search, but I don't see a way to bin search for the actual point at which all values of a function change from false to true.
Rather, it seems to be greedy: it would just grab the first true it finds, rather than the minimum true.
How would I do this in C++?
The inputs of my search function would be as follows:
...ANSWER
Answered 2017-Mar-24 at 21:33You can implement a custom iterator that "points" to true or false depending on the index it represents and use std::lower_bound function to find the first true value.
