This weekend I’m roaming a bit afield of my normal haunts.
I’m looking at service hosted JVMs in windows and in particular having such a service interact with the SERVICE_CONTROL_PRESHUTDOWN message. Handling this message allows a service to defer shutdown while handling activities that it needs to complete before the actual shutdown processing begins. I suspect it may also allow that service to call AbortSystemShutdown() in order to cancel the shutdown.
I spent my sandbox time this weekend bouncing between JavaFX and various java spring topics.
I have pretty much concluded that JavaFX isn’t somewhere I want to spend sandbox time. It appears to be less capable and productive than WPF for local UI work and Angular on Spring appear more broadly useful in the environments where Java reigns supreme.
Continue reading Monday morning after some java spring for the weekend…
Ok..and Kestrel seems to be the .NET Core alternative to the OWIN stuff under .NET classic.
Yet another option…in my case the OWIN side is likely more interesting as I’m almost certainly going to be doing things that need interop or similar windows-centric functionality. Interesting as a Linux facing option though. May also be lower overhead in cases where a particular micro-service doesn’t need access to native capabilities.
I am also expecting to need some sort of SSL certificate to enable TLS on these links (don’t need the full commercial cert probably as these are likely going to be expose by IP address and not on the open web). I need to understand what is needed to deploy TLS, ideally with cert verification on both ends using certs I’ve created myself and that don’t correspond to a particular URL.
In this case I’m looking to ensure no MITM attacks and to encrypt the traffic but not to ensure much more than that. I don’t want further authentication to leak and I want to protect the connection (for example for a web UI on a small ‘appliance’ that may at times be exposed to an open internet connection).
Mostly saving these to read/watch in more detail later. Options on top of options here…
I continue to bounce back and forth between self-hosted web UI and WPF UI for implementing simple user interactions.
WPF is likely to be easier to build the right sort of thing with but is a bit less flexible and more ‘backward looking’. Web interfaces require a self-hosting solution if they’re going to be stand-alone and cross more lines of language and environment.
On balance the web UI path is better as a learning experience and aside from a few corner-cases (OpenGL say) likely to result in a better user experience in the long run.
I’m still looking for the right self-hosting solution and UI framework solution. I’m going to have to settle on one shortly so that I can being experimenting in the ninecrows sandbox and getting a feel for the technology.
Current links of interest on the self-hosting front:
There also seem to be some hard choices between versions of the framework…classic and core in particular.
More to learn as things move forward. I expect I’ll wind up doing things with both/all before I’m done as they have different strengths. The sorts of things a WPF/WinForms/MFC UI can do in terms of digging into the system and being screen real-estate aware along make them of great interest.
I’m getting things going on some sandbox software projects that have been sitting on the shelf for some time. Perhaps a bit spread out but should be interesting.
I want to be able to put together free-standing service applications that expose both RESTful programmatic control and single page interactive GUIs without involving an external web server.
I’ve also signed up for several of the sale Udemy courses…started out with an impulse buy of the Unreal Engine Programming course and an associated Blender course. Added in some Angular, Node and web programming stuff. Probably more in there than I’ll have time to get to, but at $10 each I can deal.
Looking at some sandbox projects that need web interfaces.
Winding up with a big split here
- PHP/Apache (LAMP) for real site work.
Anything that needs to run up here on my hosting will be something LAMP-like. Code needs to be PHP (at least locally) with back end persistence in MySQL.
Front end should be more flexible. As long as the back ends can provide what the browser side code needs all should be good.
- IIS/ASP.NET looks like the easiest choice (with .net core MVC as the tool set) for windows integrated work. I have a few things that want to run locally on a system but present a web interface externally. These tools should provide lots of ‘traction’ with close windows integration. Probably an Angular front end and perhaps a full service on the back-end.
- Node.js shows up in many places. It provides a fast to deploy web server that is flexible and easy to code for. It is on my list in part because it has been showing up in places that are interesting and it part because it promises to support light-weight tasks where IIS would seem like over-kill.
For the front ends there are a huge number of choices out there. Of the ones I’ve seen
- Angular 2 seems to be pretty capable and well respected. I expect to do at least some work with Angular and if it proves easy to work with I may focus on it.
- Bootstrap is older (I think) but appears to provide a similar set of tools and infrastructure. If I run into issues with Angular, I may give this a try for something small and see how well it works.
I am also looking at free-standing, light weight web server options that run in C#. This is primarily aimed at RESTful interfaces to back-end code. OWIN and Katana seem to promise something like this while on the C++ side (and I expect C++ will show up now and then) microhttpd looks promising (with GPL restrictions, but these are sandbox projects).
Currently doing quite a bit of reading. Soon I’ve got to kick off from reading and get to some doing. Not sure what I’ll tackle first but I will probably try to list the things I’d like to kick around before I pick one…stay tuned.
Cool rundown of some of the transition from stop motion to CGI. In particular I had never considered that motion blur would be an issue with the believability of stop motion sequences. Makes sense after hearing the description though.
Mashable page here video here.
It is pretty amazing how far and fast this technology has moved. I’m wondering what will happen now with VR/AR as they seem to have the potential to follow the same curves. Back end them through something like AWS or a direct peer to peer link and you should be able to look at building multi-person immersive environments. Add in voice recognition to replace keyboard entry. Use either multiple camera views of the participants or limb sensors and you should be able to make it amazingly real.
