bash – Did I create my environment variables to be stored $PATH, correctly?

trying to set up my Django application to work via CURL, not working. The issue is I have to set up my environment variables.


export DB_ADMIN
export DB_HOST
export DB_PORT
export DB

export PATH=$PATH:$DB_PORT/bin
export PATH=$PATH:$DB_ADMIN/bin
export PATH=$PATH:$DB_HOST/bin
export PATH=$PATH:$DB/bin

Could I get some verification if I set up my enviroment variables correctly? I want them to be accessible via my $PATH. Thank you in advance for your comment.

My rooted tablet running 4.2.2 won’t Factory Reset? How can I create whatever file might be missing?

I have ADB enabled and wiped data but my tablet is still in a boot loop. I have another tablet that’s been altered nearly identical to the boot looped tablet so I’m wondering if I can copy a file using my cable that’ll fix my issue.
*I don’t believe a recovery.img file exists on either tablet or idk how to find it as I’m VERY NEW to any type of mods.
*When attempting factory reset with hard buttons the recovery screen flashes for a split second but tablet immediately reboots into a boot loop.
*ADB command wipe data did a wipe but tablet still won’t boot up completely.

unity – How to create terrain made of small tiles?

Whether performance is an issue depends on the size and quantity of the tiles. If the environment is 10×10 tiles, there shouldn’t be any performance issues. If the environment is 1000 x 1000 tiles, spawning 1 million tiles at once is probably going to kill performance.

If the map is very large (in terms of number of tiles) but only a small portion of it is visible at a time (e.g. due to a top-down camera angle), you can use a pooling system. E.g. say the map is 1000 x 1000 tiles but only 10 x 10 tiles are visible at once. You could spawn a 12 x 12 block of tiles, which gives you 1 row of padding on each side. When the camera moves towards one edge of the screen, you move the tiles from the opposite edge of the screen over to create the new row of tiles that’s coming into view.

Here’s a diagram with a 2×2 viewable area and 1 row of padding around each edge.

legal – Want to create pokemon fan-game, need advice on copyright

I want to create a pokemon text game. Obviously I will use various stuff that belongs to Nintendo, like pokemon, professor, region names and sprites from the games. Can Nintendo sue me or take down my game and for what? What are the possibilities?

I think it’s important to note that:

  • It is a text adventure game that lacks any mechanics of known official games
  • It is going to be absolutely non-profit, I won’t accept any money, including donations, for my creation
  • It is going to be based on a website
  • I’m not expecting more than 1000 users per day to visit it
  • To sum up, the IP of Nintendo I want to use are pokemon sprites and various names, copyrighted by Nintendo
  • There are a lot of pokemon web-games operating like neopets that weren’t currently shut down

I would be very thankful for any advice or help!

p.s. Sorry for my bad English, that’s not my mother tongue. :^]

wifi – Can someone create a fake phone number and impersonate my IP address?

I’ll try to keep this short. I am involved in a defamation civil lawsuit. I did not author the posts, but the plaintiff believes I did and seems to be doing everything in their power to make it seem like I did.

Every time there is an event in the case in my favor, I get some sort of notification – reset request for a social media account, a verification code for various dating apps, etc. I only began receiving these when the case began. Perhaps trying to dig up dirt on me, but unable to.

Yesterday was a case event and this time, a masked phone number texted them in the middle of the night threatening to post embarrassing photos/videos of him/her being cheated on by their spouse. Again, NOT me or anyone I know. Something is very suspicious about this and I’m afraid of being set-up on their end. They do know my address and IP address. They do not know the new WIFI password. Maybe this is someone legitimate, but the timing is highly suspicious which makes me think there is foul play on their end.

So my question is, could they set me up? I mean, could they have set-up a fake number and made it look like it came from my Wifi? Or really me in any way? I wouldn’t be surprised if they hired a hacker (they are these types of people). If someone on my network accidently clicked a suspicious link, could they get in? Is there a way for me to tell? I want to be ready for the worst when the subpoena comes back.

Thanks in advance for any help!!

c# – How to create a modular system of multiple .NET Core applications extending a single application?

So first of all let me explain what I want to achieve:

I want to create a basic .NET Core console application which is responsible for loading external extensions (more on this later on), listening for events, connection handling etc.

Let’s assume this application is a Discord bot or Amazon’s Alexa. It is responsible for starting, shutting down, connecting and so on.

But you want to provide a system to extend this basic application with a plug n play system. So instead of extending the core repository you would create another repository with a .NET Core library which provides a new feature/command/skill.

At the end you would have a core application in one repository and multiple repositories extending the core application.

How to develop this?

Let’s assume

  • Developer A creates the core application in a repository myApp.core
  • Developer B wants to create a “Hello World” command in a separate repository myApp.extensions.hello-world
  • Developer C wants to create a “Ping” command in a separate repository

Developer A could work on the application it’s easy to test locally.

Developers B and C create libraries for their features. To get their libraries loaded into the application Developer A loads all DLL files from a specific directory “Extensions” during startup.

But how could Developers B and C test their new features if they want to debug the libraries in their IDEs? They can’t run that library so they have to test that library by running the core application.

Things might get tricky if developer A is an employee and developer B and C are just customers creating their own commands but don’t have access to the core application.

So how would developers B and C debug their libraries locally then? Are there any better approaches for this? Maybe Docker helps out?
