Windows & Service Development

 As a consultant I've been able to start developing application and services at the lower levels of the operating system. Which is pretty interesting compared to what I use to do. I find myself doing the same thing with my web development.

EFCore - Parallel Async

Currently dont have any use for it. https://stackoverflow.com/questions/44063832/what-is-the-best-practice-in-ef-core-for-using-parallel-async-calls-with-an-inje https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/ I've also been moving away from EF in favor for Dapper, still using tasks that might be unless until I write myself an example.

Handling Raw Html

For sometime now I've been at a point in my research to find the proper way to handle raw html. Sometimes you need your api to push raw html with syntax that can't be edited once its submitted.  Handling all html in a 2D array where the first in just the html tag and the second is a child's value which can also be a html tag. { ["p"]["test"]  This may also be another case to start my project with a headless orchard core project. Using fluid syntax might be the better way to allow an api to take information and using a custom javascript library to convert html to the api?

Image Enhancement Research

For some of the projects I have in mind this would be a great way to handle poor quality images, for example schematics that have low pixels. From there I would have an easier time convert to svg files but that is a project later down the road. For now this is something I need to keep in mind of. msmsajjadi/EnhanceNet-Code: EnhanceNet: Single Image Super-Resolution Through Automated Texture Synthesis (official repository)

Linux: Managing Security & System Logs

Not a linux novice by any means, so this last year (2019) I had been tracking logs on my server.

Aspnet Dotnet Notes: Custom Authorization & App_Data

Trying to handle a secure folder  where the files are not pushed to the server at deploy. Like all files in wwwroot they are in source control, these will not. The files I'm storing are so big that moving them is a separate process do outside of my application. https://stackoverflow.com/questions/36775942/how-do-i-serve-static-files-only-to-authorized-users https://github.com/ClintBailiff/MiddlewareDemo/blob/master/Startup.cs get current user   inside an MVC controller: From the  Controller  base class, you can get the  IClaimsPrincipal  from the  User  property System .

Mongodb Cheatsheet

This cheat sheet is based on the latest version of mongodb, which initial had setup and didn't encounter any problems. However that all changed when I was working remote and forgot I disabled the port no my network, rather than with the server. So I went pointing around where I didn't need to and ended up messing things up. The Best tutorial out there is of course on digital ocean for my setup on ubuntu 16.04 , this articles isn't so much about getting setup. I just wanted to include it because I found myself looking back at it to see if I missed a step. Bugs/Problems Now comes all the messed up things I found and had to deal with. firewall - Port seems to be open, but connection refused try using 0.0.0.0 in the bin_ip for the /etc/mongo.conf try sudo ufw disable and check to see if it works without the firewall (probably still wont but worth a shot), then just sudo ufw enable. Make sure port 27017 is open. Then check this  linux - Connection refused to MongoDB e...

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loo...
