Network checking in WinRT(C# implementation) - windows-8

How we can check the status of network in windows 8 metro application. ie the availability of different networks(3g,4g, wifi etc)

Try this method, I think this is the simplest form of checking network availability in windows 8.

navigator.connection downlink shows a maximum of 10Mbps

Using this API: https://developer.mozilla.org/en-US/docs/Web/API/Network_Information_API
You can run $ navigator.connection in a browser console to receive your different values regarding your network connection.
However the downlink attribute is a max of 10 (aka 10Mbps). Why is it capped here? Doesn't really help me since I need more info since I am deciding whether a client can handle HD video that may very well require over 10Mbps, thanks.
I found the answer in the comments to this answer: https://stackoverflow.com/a/47511842/3973137
Turns out Chrome caps it at 10 Mbps to prevent fingerprinting

OS X WebKit possible to recieve connection speed?

I am workin on a small internet browser in Xcode for OS X using the WebKit framework and I was wondering if it was possible to get a WKWebView's live connection speeds (Upload and Download) to the website and display them in Level Indicators (and write values next to them in textfields). (or any alternatives if not possible with WebKit) Thanks :D
To determine the actual speed, you need to measure the time it takes to upload or download a buffer of known length. If you just need to know if they're connected via WiFi or some other (presumably slower) method, there are ways to determine the type of connection you have. Here's a random example I found for doing this: How to check for an active Internet connection on iOS or macOS?

Is it possible to test the CAN loopback mode without using oscilloscope?

I am working on the CAN on LPC1857 microcontroller. This is the first time I am working on the CAN driver.
I am right now testing the loopback mode in CAN. I have successfully transmitted the message. This I know because of the values in the status register. But now I need to verify whether I have received the same message at the receiver end. Since I do not have any oscilloscope with me, I wanted to know whether it is possible to check the output at the receiver end using software. I am using LPCxpresso IDE for the coding purpose. If yes, can you please give me a brief idea about how it is done?
Any help is appreciated.
Thanks,
Pavan.

Replicate poor wi-fi for testing

I want to test an iPad app that needs an internet connection. I want to sit at my desk next to my router and test it against a poor wifi connection. How can I replicate a really poor wifi connection? Wrap the router in tin foil? Try and limit the router connection speed to the internet?
Thanks.
In the end I tested the app using the iOS simulator in Xcode on a Mac, then used the excellent Network Link Conditioner tool (that comes with Xcode) to tune my network speed as required. Worked a treat.
Better ways to do these tests are to use RF isolation chambers.
Did you try reducing the power levels on Access Point to minimum?
On a different note, if you want to have a bad Wi-Fi environment,create lot of interference on same channel from another Access Point.

How to program midi messages to HUI Pro Tools uses?

I found some specs online but It wouldn't work for Play.
I tried
const UInt8 noteOn[] = {0x90, 127}; and it didn't work.
Does anybody know what midi messages to HUI Pro Tools uses for play and stop?
There are 2 main Protocols out there for controlling DAWs, Logic Control and Mackie Control (HUI). Unfortunately both are close protocols. Only recently Apple added support for TouchOSC (iOS application) and the OSC protocol (Open Sound Control) in general for Logic Pro, hopefully Pro Tools to follow (maybe it already did and I'm not updated, you better check it out).
If you want to reverse engineer the record/stop buttons and you own some sort of Mackie Control device, I recommend using Midi Monitor or LC Xmu to monitor what data gets in. Not sure whats there for PC users, on my PC era I used my Pro Soundcard.
If you don't own some sort of controller and looking around the internet for the answer please notice that these protocols have many versions that each manufacture tweak a little bit. On the other hand, there are not that many options, you can try them ALL :)
Anyhow, I program an iOS application that controls Logic Pro without using LC or MC at all. I opened Logic's Key Command and set the Midi Listen button of the Start/Stop on, then sent some Midi Note from my iOS application to calibrate the button. It worked well, but was not intuitive to users so I decided to give up.
You can send a midi machine control message through your virtual server with you virtual server, I had some success after reading this: http://en.wikipedia.org/wiki/MIDI_Machine_Control
Be sure to enable your virtual source as a mmc in your DAW. Also there is a Boolean check in the core midi docs you can use to verify that your program is sending the mmc messages, I believe it is something like kmidimachinecontrolenable, it is a coremidi constant and should not be hard to find.
