I tried running a Meteor.js app on my Samsung Smart TV (2013 I think) stock Internet Browser and received "out of memory errors". I'm interested in see if any can or has run a Meteor.Js app on some of the latest SMART TV Browsers...
eg. I tried a running a sample app to test Meteor.js Streams package...
Just curious...thanks for any feedback!
I am doing some work against LG Smart TVs and have been debugging out-of-memory errors as well. Two major things: large client side minimongo databases are all in-memory and can contribute to the issue. Usually just limiting how much you publish on the server should help. Secondly, images. Those are likely your main culprits. These TVs don't understand single page apps too well and will only flush memory consumed by images when the page reloads.

I am attempting to install Cubase Elements 10.5 'stay at home trial but fail to get any audio.
I have followed numerous guides online about shuffling various Gb files around (surely thats the installer job) but still nothing.
All audio mapping shows as connected.
When testing eg using the Production > Blues Rock Production (so its not even setup), for each Channel I get the error message:
The current preset or project was created with a previous version of HALion Sonic SE. If you modify the preset using new features of this trial version a previous version might not be able to load it or the preset might sound different
if I just click ok and load the project it seems to play, but no audio or output levels show.
I am getting nowhere with Steinburg 'Support', raised a support request and this is just ignored.
I have been trying to get this working for about a month and installed several times.
VST Connections
Audio Device and Driver
The application is in focus when it fails to provide audio, not sure where to make it play in background.
Screenshots of fault:
Chose a project as test, but when loading each of the channels shows this error,
I click ok to make it load:
Press play, no sound
but see it playing here:
Attach a screenshot of your VST connections in Cubase to help others diagnose your system.
Ensure you have latest drivers for your audio card etc.
Ensure your operating system (or any other background/foreground app) is not using the outputs you have selected in Cubase.
as they may not be multi-client.
ASIO compatible hardware is recommended.
Ensure background audio is enabled in Cubase if the application is not in focus.
Confirm that you have followed at least the steps above in any further replies. Specify your level of experience with computer audio in general, so that further information is relevant to you :-)
I acquired a batch of WT0490 wearable pdas with detachable scan head, so converted an application originally made for Windows Mobile (which has been running perfectly for several years) to run on the WT4090s. The devices use these versions:
Windows CE 5.0
EMDK 2.6
ASP.net CF 2.0
Since rollout I've seen some very frustrating behaviour, which seems to start happening after the devices have been operating a few days. Users are reporting the following error:
Unexpected error in application
SCAN_Enable
There doesnt seem to be any noticeable pattern, several devices will be working perfectly for a few days then suddenly this error will show. THen a few days and a few reboots later they work again.
All devices were taken right back to stock settings then our cabs deployed to them. All identical models. We've tried altering memory allocation, swapping scanner headers etc but there is no pattern.
The error seems to occur on load of the first form after login, the login screen displays a list of users in a dropdown with a password box so that part of the app works ok, it seems to be when the scanner is initialised that this failure happens.
I had 40 devices, now 30+ have gone down with this same issue so my gut is telling me its a software issue but as yet ive not been able to find out why.
We've tried warm boots, cold boots, complete reprovisionings as well. We have a couple of dev units that don't show the problem although they are not in regular use so maybe we just haven't seen the problem 'yet'.
I hope someone out there has had this issue and knows how to fix it.
Thanks in advance.
WT4090 was built by Motorola Solution enterprise business, now part of Zebra Technologies. The WT4090 is currently in EOS (End Of Sales) but is still supported by Zebra if you've a maintenance contract.
You can check if you've the latest OS version and fixes installed on the device looking on Zebra Technologies support website.
For question on how to develop for Zebra Technologies devices you can take a look at Launchpad, Zebra's developer community website.
It's Worth noting that these devices have detachable barcode scanners - so if the scanner is not correctly attached, you get a SCAN_Enable error.
If you don't release the scanner, you can also see this error as a previous form could have the scanner blocked.
You may also find you have the ScanWedge app running - this will also block the scanner so you cannot get it enabled. The EMDK needs exclusive access to the scanner to enable it.
Backstory
I have recently moved to a more rural area for a few weeks. Unfortunately there isn't a fixed internet connection here, so I have been using a 3G modem. Data is expensive in Australia so I have been monitoring what applications use the most data and shutting down everything that I can.
Question
I have noticed that I have a peak of network traffic every time Android Studios successfully builds one of my apps. According to the mac Activity Monitor the peak is about 3.2MB. I have tried turning off usage statistics however that doesn't seem to help.
Does anyone know what is causing this network burst and how to stop it?
More Info
I have included a Wireshark dump in a zip for anyone interested in taking a look at the packets. I can tell that it is going to Google at the 74.125.237.78 IP. Data is quite expensive here in Australia and I'd like to minimise my cost while I have to use a 3G modem.
Gradle connects to the internet to fetch dependencies and to make sure you have the latest versions of dependencies (if you specified versions as 1.2.+).
If you would like to disable this, in Android Studio 0.5.1+ you can enable Offline Mode by navigating to File->Settings->Gradle->Offline work.
But note that even in offline mode, Gradle will still connect to the internet periodically (every 24 hours) to ensure that dependencies with versions that use '+' are up to date.
My laptop's processor doesn't support SLAT so I can't run the WP8 emulator on my laptop and use that to take screenshots.
I have a Lumia 920 and I can take screenshots with it, but only for one of the three screen sizes available on Windows Phone.
Is there any way to take screenshots for all the different screen sizes in this case?
I had the same problem. There is not a way to have your Lumia 920 render in a different resolution if that's what you're asking. This makes verifying those resolutions pretty tough. It really makes you have to trust in your layout that your application can scale correctly.
To get the screenshots, I used my Lumia 920 to take screenshots, then I used paint.net to resize the images to the correct sizes for the store requirements. It's a little misleading to the user but it's all you can do without having the devices you need to test.
Other options would be to reach out to your local Microsoft developer evangelist to see if you can get a device to test those resolutions. Then if all else fails and you're still not comfortable shipping your app without testing on those resolutions you can always find a developer friend that is willing to run your app on their emulator.
If you're using a Windows Phone 8, you can just press the Power and Start buttons simultaneously to take a screenshot.
My company has a Compact Framework.NET WinForms application which runs on rugged handhelds manufactured by companies like Motorola, Intermec and Psion. These are expensive devices with built-in barcode scanners that are used in harsh conditions.
The configuration of the handheld application is managed by business users through our web site. The devices pick up the configuration when they sync from within the handheld application. Field workers use the handhelds, business users use the web site.
The business users have expressed the desire to, for lack of a better description, configure and preview or even fully use the actual handheld application through a web browser. They want to make configuration changes in the web site and immediately see what the impact will be in the handheld, without having to have a physical device (again, the devices are quite expensive). They want to be able to create training materials or conduct sales meetings and be able to demonstrate the application to their customers without having a physical device on hand.
Microsoft offers several Device Emulators, but they are probably too complex for business users. They are developer tools. One idea might be to somehow use the emulators within virtual machines possibly in conjunction with Terminal Services or even some kind of clever screen capture/VNC to show an emulated device in a browser. I suspect running emulators in the fashion may not exactly be a scalable solution, however. Also, only one emulator at a time on a single machine can be "cradled" and connected to network.
I'm looking for any suggestions which might help me meet the business users' requirements.
Thanks.
The only thing I can think of offhand is not that simple, but would probably be useful (and certainly the only "true" way for them to test).
I'd create a service that works like the Remote Display app (part of the WinMo Developer power tools, also ships with Platform Builder for CE), in fact it might just use that app (the source code for it actually ships with Platform Builder, so the eval version of PB would get you that source).
You would then create a web interface that acts as a "shell" for that service, marshalling the display image out to a web page and image clicks back as mouse events to the device.
