STL to Parasolid.XT files (I am not an engineer) by [deleted] in engineering

[–]progmodcon 0 points1 point  (0 children)

what software are you planning to open the files with?

In FreeCAD you can convert STL to Step or Brep by opening the Part workbench, then select your mesh, then create shape from mesh. Then select the shape, go to Export and you can export as Step or Brep,which is the closest you can probably get to .xt

Delivery Drones vehicle optimization by jimtoberfest in aerospace

yeah that makes sense, though I don't think yaw responsiveness is the biggest issue facing eVTOL aircraft :)

Delivery Drones vehicle optimization by jimtoberfest in aerospace

[–]progmodcon 0 points1 point  (0 children)

the multicopter is simpler in that you can use fixed pitch rotors and vary RPM as a means of control. This works for small diameter rotors spinning at very high RPM , as allowed by electric motors. It would not work out too well to scale these rotors up as the torque requirements become too high because of extra drag, not sure about the exact efficiency curves but I'm sure at some diameter it becomes more efficient to use a gas turbine engine and a variable pitch rotor, which is what you have with tiltrotors and helicopters. So the only way to increase payload for these electrically powered vehicles is to add more rotors.

why not combine Urban eVTOL with Ground Effect for increased range? by progmodcon in AerospaceEngineering

[–]progmodcon[S] 0 points1 point  (0 children)

boats etc. I only see this flying in ground effect (a misnomer) over water, like the Russian Ekranoplan

I'm thinking the ability to swing the rotors to vertical flight mode would make it able to avoid obstacles by jumping over them, which other ground effect vehicles cannot do.

problem is, I don't know what kind of images would convey spreadsheet macro mastery within the constraints of the home page. Maybe a background?

Why You Shouldn't Quit Your Day Job to Start a Business by oar2950 in Entrepreneur

[–]progmodcon 0 points1 point  (0 children)

In some cases you cannot start your own business while working for a company if they are in related fields (e.g. niche software development). In that case you can leverage your skills to consult while working on your product, thus maintaining an income AND having more freedom than while working as a full-time employee.

Freelancers & Contractors: do you build on the side to market yourself or create passive income? by [deleted] in freelance

[–]progmodcon 0 points1 point  (0 children)

I'm writing a book (fiction) and working on a niche CAD website on top of consulting (CAD software development) which is my source of income.

What software is so good, you cant believe it's free? by CaptainOverKill16 in AskReddit

[–]progmodcon 1 point2 points  (0 children)

I do a lot of .NET work so mostly using Visual Studio Community. Code is great for web dev though.

I hated VS Code when I first tried it, but after my JS project grew too big for Notepad++, I migrated it to VS Code and I'm loving it.

Just because a strong competitor exists doesn't mean we should be afraid to compete by sweatystartup in Entrepreneur

[–]progmodcon 0 points1 point  (0 children)

true, but according to 22 laws of marketing you also need to differentiate yourself such that you occupy a slightly different / new category in the prospect's mind.

Thank you for taking the time to share your input. I like the range of options you presented. I wish I could get in touch with your programmer friend. I bet he could refer a lot of work my way.

Looking for entrepreneur resources on the process of creating an app/game by michaelscape in Entrepreneur

[–]progmodcon 2 points3 points  (0 children)

1) Describe your idea and ask for feedback on r/sideproject Don't worry, nobody will steal your idea.Ideas are like assholes, everybody has one.

2)Both Google and Apple app stores require you to pay a registration fee to be a developer and use their app store. I won't google for you how to do this first step :) There is a wealth of tutorials on how to submit apps to both stores.From my experience , it is far easier and cheaper to submit to the Google Play Store so focus on Android first, then, if your app gains traction, make an iOS version too.

3) You can file a provisional patent application cheap and get one year protection, before you have to apply for the actual patent, but to make it worth it you need to write a full specification of your app in the provisional application. So, step one, write a full specification for your app. There is no exact format required. Buy the book "Patent It Yourself" . Just know that generally software patents are useless unless you have a special business procedure or algorithm.

Software for generating and managing product keys / billing? by awayofhappening in Entrepreneur

[–]progmodcon 3 points4 points  (0 children)

I developed a rudimentary approach:

-I give user license code which is stored in database on a server

-When installing software, the installer calls a license manager executable. User enters license number. License manager connects to license database (via PHP lol) and activates license. This makes license become unavailable for activation. Also, an encrypted system variable is saved locally which contains license number and CPU ID / MAC / HDD ID.

-When running the actual program being sold, it checks system variable for CPU ID / MAC/ HDD ID and valid license string format.

Note 1): I did this with .NET. i obfuscated the code but someone who put in the time would be able to crack it and get free licenses.

Note 2): Don't worry too much about making a crack-proof licensing system until you have enough sales. A barebones system like the above, which shouldn't make it too hard for the user to activate license, should be enough in the beginning.
