How to change screen resolution on Oracle Windows Compute Instance? - windows

I am a new user using Oracle VPS with Trial Credits, and I was wondering how do I change the screen resolution from 800x600 to 1920x1080? I found the articles below, but am unable to see the solution, and I am unsure if the below articles would be the solution. I don't really know how to navigate the Oracle instance, so I may have to change something there, but again I am not sure. Any help would be greatly appreciated!

I tried running QRes as well as using Set Display Resolution command, but those did nothing.

Facing issue while exporting at 1920x1080p in principle for mac

Am using Principle for Mac prototyping application, I have tried to export the sample video in the size of 1920x1080p. After exporting the video is not rendered properly, it stays in the first frame. Could you please help me about this problem.
I have found the solution for this, Principle application could not able to construct the interaction for the heavy file (i.e, my file has more than 50 slides) this is the major for the issue.
Thank you:)

Code Combat not interacting locally

I wanted to install Code Combat locally to be also able to understand it better. I have followed the steps (for Mac OSX, I have Yosemite) described at: https://github.com/codecombat/codecombat/wiki/Developer-environment
Everything worked. I have all the scripts running, without problems, mongo is up and running, the game is starting, but then, the game itself can't be proceeded.
I haven't restored the mongo dump, which is 2GB fat and which I can't download easily with my current internet connection, but it seems to be optional.
Looking on the console, I have a couple 404 that I can't explain, see below. If somebody could help me to get the game running locally, I would be very grateful.
GET /db/thang.type/529ffbf1cf1818f2be000001/version 404
GET /db/level/dungeons-of-kithgard/session 404
As well as the mp3 files, which I am fine not to have.
Thanks in advance,
Matthieu
PS: I would have liked to specify more tags, but as it concerns many languages and doesn't have a specific tag, I didn't know which one to add
OK, it's mandatory to have a mongo dump to have the base elements for the levels. But 2GB is too much and a solution will attempt to be found to be able to export only the required data. 200MB should be enough
UPDATE: With the following ticket being implemented, the size is reduced to less than 100MB: https://github.com/codecombat/codecombat/issues/1988

Live, evolving, dynamic wallpaper (desktop) on a Mac

Should it be possible to develop a dynamic desktop for the Mac? By "dynamic," I mean a desktop whose images take system parameters, such as the time and job information, and use this information to update the image. Information about image states would also be preserved between sessions. I'm not talking about a movie or a stochastic but autonomous screen saver. Is there any reason a user couldn't develop such a thing? (I'd like to ask how but am trying to keep the question constrained.)
I'm not new to programming but have no sense how Macs work. I'd like to know if there's some fatal flaw in my goal before I start digging in. Thanks in advance for any pointers.
Update: Wikipedia implies there's no direct way to do what I want to do--Mac desktop wallpaper must come from a folder of static images or a screen saver. The only viable approach I see at the moment would be to generate images periodically for such a screen saver (e.g., by adapting this Python script). If this is stupid or a slicker method might exist, would love to hear it.
Very late response but I only stumbled across the question and noticed some recent interest...
Aren't you looking for something like GeekTool ?
This seems to have been implemented in the latest version of Mac OS X: Mojave.
This article has some tips on how to make your own, towards the bottom: https://www.howtogeek.com/369645/download-more-dynamic-wallpapers-for-mojave-or-make-your-own/

A Good, Free screen sharing program for pair programming?

I am looking for a good, free (preferred) screen sharing program that works well for pair programming and code review sessions for Windows (Vista x64, Server 2008). It should allow either person take control of the screen and be fairly responsive for text editing over decent broadband connections. Additional features like the ability to draw/mark/annotate the other persons screen would be nice.
Edit: This will be used by developers in remote locations.
TeamViewer from http://www.teamviewer.com/ works very well. We use it for pair programming between London and Ukraine.
Notes:
We use Skype for voice.
TeamViewer uses extremely low bandwidth - 4kbyte/sec on average for programming in Visual Studio 2008 # 1024x768 resolution.
Can swap roles from hotseat to viewer with a button.
The remote view of the screen can be resized to fit in a smaller area with no loss in usability.
Windows Shared View works for me. It allows you to only share certain windows and even shows where your "attendees" mouse is. It would be best to use that in connection with some sort of voip connection so that you don't have to type questions/responses back and forth.
I have checked some hours now for a good one.
Best and the simplest thing i have found.
http://www.screenleap.com/
Free, no strings found so far.
No need to waste time installing or registering anything.
Works perfect with "share are only" if you have multimontor setup.
Most other software shares full screen default, and you cannot choose which monitor you share.
You need to be aware that it does not encrypt data. Check FAQ.
But if you have to run voice over Skype/Mymble/Whatever separate anyway..
What harm can a hacker do by simply getting 50% of the conference ?
Pff.. Oh you wished for screen sharing.. this one does not have it.
So try: http://www.mingleview.com/
It has that multimonitor "bug" and you need to install a simple pluginlike thing.
But "take control" is there and it's very simple also.
Most other software has bundled unneccesary functions like calendaring, document system, filesharing which i already have solutions for.
It's like developing games on excel macros..
unneccesary.. developers please learn that already !
I haven't actually tried it yet, but it looks promising. Check out DimDim. They have a free web service and a VMWare image on Sourceforge.
If you're using eclipse, you might wanna try ECF. There's a video presentation available here.
Try Mikogo at www.mikogo.com
very easy to setup. no problems with Firewalls etc etc
And my final suggestion, but this is not one I've tried. Go to Crossloop
On OSX, I've used vim and a multi-user GNU screen session - this gives much better responsiveness than VNC, screen-sharing, etc. I guess you could use these with Cygwin?
I like to use Screen Hero, which allows both users to use the mouse on the shared screen: http://screenhero.com/
or Zoom: http://zoom.us/
For a poor-man's solution, you can use the free edition of RealVNC. On the server, un-check all of these boxes:
(source: realvnc.com)
Would a VNC client not do the trick, combined with a one of those screen overlay apps people use for presentations (screenpen rings a bell)?
Another option is to use VNC, but use reverse connections. Have a look at this I use this in conjunction with No-IP to get a fixed address.
Do you need this to be remote?
You could just have two monitors set to mirror and 2 USB keyboards/mice
If it is remote then VNC is the way to go, I would use UltraVNC if you are looking for a free version, it has more features (chat, file transfer) than the free version of VNC - it also has a video driver hook that means it suffers less from any weird screen issues than regualr VNC.
If firewalls are a problem you can simply set up a VPN (which is probably a good idea anyway - although ultra can do encryption).
How about any of the services like Joel's https://www.copilot.com/?
Have you looked at the collaboration module that comes with netbeans? Its very useful for pair programming!
For multi-platform simplicity, I would suggest
https://join.me/ for screen share (you can even view a remote
screen using iOS!)
getting a phone headset, and using the phone for audio.

API for getting screen region changes?

I am writing a sort of screen-recording app for Windows and wish to know when and which regions of the screen/active window have changed.
Is there a Windows API I can hook to get notified of screen changes?
Or would I need to manually write something like this? :(
I always figured that Remote Desktop used some sort of API to detect what regions of the screen had changed and only sent back those images - this is exactly the behavior that I need.
I don't think there is an API in Windows that can tell you which parts of the screen have changed.
One possible way is using a video mirror driver like UltraVNC uses.
I think you'll find some clues here Screen Event Recorder DLL/Application, here About Hooks, and here Writing a Macro Recorder/Player using Win32 Journal Hooks
It would seem that you're going to have to do a fair bit of work to detect screen changes. This posting at tech-archive.net for instance. With this you can copy to RAM a reference screen and then take another and compare the two. It'd be up to you to define what kind of a change is a meaningful one. It's similar material to this article on desktop capture.
I think Remote Desktop streams GDI like commands. I don't know how they capture them in the first place.
Thanks for your help everyone. I ended up writing an image differencing class which seems to calculate the changed rectangles suprisingly quick. I've posted the gist of how it works here.
At the moment I'm just doing it in a timer but planning to do it after input events too.
Thanks heaps for your links Boost - I've only just looked at this thread again so I'll check them out soon.
