I still get goose bumps reading that article – but then I am a geek, if that wasn’t obvious. Whilst, grid computing with GFS, MapReduce, Hadoop, are still very much relevant and great (and most others still trying to use and understand it); Dynamo (from Amazon) and BigTable lead to NoSQL which is great and still worth spending a lot of time learning, playing, and, experimenting – I would love to hear on what they are doing now with Colossus (think of that as GFS vNext), Caffeine and, Spanner.
7 years is an eternity and who knows what is cooking? And of course what are both Microsoft and Amazon doing to compete around this. How can you not continue to be excited the world we are living in? 🙂
Microsoft just announced an update around the HoloLens that allows you to share on what you are seeing (from a first-person perspective) with others to make to more interactive. This is a combination of MRC (Mixed Reality Capture) which already exists and some new updates that address some of the short coming of the MRC – especially when working with a audience.
The main use case on the spectator view – as the name suggests is to allow those in the room not wearing a device to see the holograms but also the interactions that the folks wearing HoloLens with their mixed reality experience.
You can use this to capture a mixed-reality scene, live stream the content (say in a meeting / conference), and, shoot/record the video. This essentially is the ‘cheap’ version of the special camera rig that Microsoft uses for keynote presentations.
It is not as straight forward as you might imagine; but at the same time if you are doing this ‘properly’ it isn’t as complex as well. You need some special equipment, and need to change some configuration, and add details to your apps to account for this.
You do need some special DSLR cameras (with HDMI output), and some other hardware – details can be found here. You can also 3D print the mount (STP can be found here).
And in addition there are a bunch of other steps that you need to do – from calibrating (to get the offset from the camera), to the Compositor (which is a unity extension) and allows you to record the video and change the hologram opacity, spatial mapping data details, etc.
I have been using Mouse without Borders, a program that allows you to make a virtual KVM between machines for some time at home and it is awesome. You can use one set of keybard and mouse among various (windows) machines including clipboard and copy and paste. If you haven’t tried it, I would highly recommend it.
However lately I could not connect between two machines and kept getting the error: “Only one usage of each socket address“. To the point where it was unusable and was pretty annoying. I looked online at their site but nothing jumped out. BTW, I was seeing this only on one machine (running Windows 10) and not the other one (also running Windows 10 but an inner ring of the Creators Update – essentially the next version of Windows).
What I understand the issue to be is that Windows is running out of ports and where programs that use a port for a short time, it won’t matter much, in this case the port is always going to be used.
The solution that seems to be working for me is quite simple – we increase the number of ports available to Windows. This is quite simple and to do this if you run an elevated command prompt and copy and paste the following command:
netsh int ipv4 set dynamicport tcp start=1025 num=64511
And if you are not sure on how to get the elevated command prompt – easiest way to do that is press WinKey + X, and from the menu select Command Prompt (Admin) as shown below.
