I'm pretty sure this is a hardware issue. Just to prove my point, I loaded up the Blink script and the default startup file, both resulting in the same error. I'm worried I may of fried something or done something similar. I'm fine if the only solution is to buy a new Arduino, I'd just like to know what happened.
Here are is error message from both scripts:
Startup File
Blink Script
No errors occur when compiling, but when the code is sent to the Arduino, that happens. Any ideas on what the problem is?
It's hard to tell you what happened without knowing what you were doing with your board before it stopped working.
This error may have many causes, one possibility is that you downloaded the .org IDE, which has a higher version number. In this case it should be sufficient to uninstall the Arduino IDE, then download the latest .cc IDE from here and install it. Be sure to make a backup of your sketches first.
Your problem may also be a corrupt bootloader, in which case burning the bootloader may help.
If u have another functioning arduino with same processer(atmega328 in my case) than burn bootloader on ur malfunctioning arduino using ur function arduino

Anybody else failing to open snapshots once they upgraded their VirtualBox from v5 to v6? Snapshots that were opening just fine are now failing for me with this error ...
HGCM#0: Bad auto mount point size: 0x5
[ver=3 pass=final] (VERR_SSM_DATA_UNIT_FORMAT_CHANGED).
Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Some very old snapshots are able to open; but most new ones and ALL the ones I save now using VirtualBox 6 are failing to open. Same error above.
My host is Windows10 and the saved VMs are Ubuntu18 guests.
Disclaimer: It should not be an excepted solution as your saved state will be lost.
As I don't have any sensitive data in the saved state. I have discarded the saved state and it works fine for my case.
EDIT: in some cases it looks like if you take a snapshot using the saved state, and then discard the saved state you might be able to recover back to where your saved state was
Steps
Right Click on the OS
Select Discard Saved State... in the context menu.
Screenshot
Host OS: Windows 10, Guest OS: Ubuntu 18.04, on Virtual Box 6.0.0
I have resolved this problem by installing Oracle_VM_VirtualBox_Extension_Pack-6.0.4.vbox-extpack for my VirtualBox-6.0.4-128413-Win

After some time I've got this problem with my C++ compiler.
When I write the code and I compile if for the first time, there's no problem and I can execute it normally. But then, after the program is finished in the terminal, if I make any change in the code and try to compile it again, I get this problem:
c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot open output file C:\Users\gabri\Codes/test.exe: Permission denied
collect2.exe: error: ld returned 1 exit status
And I get access denied when trying to run the .exe file after that.
I have no idea how to solve it. I try to compile usually in Sublime but even in an IDE like Codeblocks I get the same problem.
I don't know if it might help, but this is an image of my PC's Path, just in case.
Seems like you are trying to compile even when the previous process is still running. You must track it from task manager and kill the process before you compile it again.
Looking into your comment,seems like a permission issue may be,check if you are running the command prompt or the IDE with admin privilege or not,if no,try running it with administrator privilege.

I have a windows c++ application which runs under the normal (non-admin) user. I want that no user should be able to close/stop/terminate this application by any means.
Is there any active directory group policy available to achieve this or I need to do some programming for the same
The only way I know is that your app will launch run 2 or more background processes that check every few ms that your app and the other backgrounds are running, if not it re-launches them.This makes it very had or impossible to terminate your app manually.
You application might need to save its state to disk , if it needs to re-launch to the same stat is was when destroyed
you can also disable the close button or whatever can terminate your application. Also disable the taskmanager so users cannot kill your application
There is a technique called hooking which will allow injection of your code into Windows DLL's, altering certain behaviours performed by the operating system.
This would prevent the operating system killing these proccesses using the core DLL's.
There is a downside to this method though as it may flag up as a virus on anti-rootkit systems as this is a technique often used to prevent the user from killing an infection.

I'm sure this is a simple question, but I tried a couple google searches and wasn't sure what keywords to search.
After executing my program in C++ the .exe window that opens is only showing the bottom part of my output, while cutting off the top. Any thoughts on how to view all of my output?
Thank you.
You can redirect the output of the program to a file:
your-program.exe > file.txt
Alternatively, you can pipe the output into more:
your-program.exe | more
This will pause the output of your program when it fills one screen until you press the space bar.
Both approaches have their pros and cons: if you redirect the output to file and open that file while the program is running, you might not see the last chunk of data, because the OS might buffer the data before writing it to hard disk.
If you pipe the output into more then the execution of your program might be suspended while more is waiting for your input.
[Edit: incorporated enhzflep's suggestion of using a redirection to a file.]
suppose you have an "a.exe" program
execute　the program like this:
a.exe >1.txt
and open the file "1.txt" with notepad or other editor(such as notepad++).

Im trying to run Ubuntu in a virtual machine on virtual box. So far I have reinstalled virtualbox once to see if it was the cause, then I redownloaded the .iso, but when I try to run the machine it says it still won't run.
Failed to open a session for the virtual machine ubuntu.
The virtual machine 'ubuntu' has terminated unexpectedly during startup with exit code 1.
Result Code: E_FAIL (0x80004005)
Component: Machine
Interface: IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}
If you didn't power off the vm after last run, try right-click on VirtualBox Manager >> Discard Saved State. This will start the vm from (virtual) power off state. Current state of vm will be lost.
Are you using VirtualBox 4.3.14? There's a known bug which could be related: https://www.virtualbox.org/ticket/13187
I was having this problem, downgrading "solved" it.
Here's what I did and it worked properly:
(1) Move/copy your hard disk image (my_old_vm.vdi) to a
convenient folder, e.g. C:\my\VMS\my_new_vm\
(2) Create a new virtual machine (click the new button).
(2.b) At some point in time you are asked about the disk
to be used; choose 'existing disk image' and browse
to where you moved my_old_vm.vdi and select that.
(3) Start the VM and reconfigure the machine settings.
(4) Possibly delete the old machine. If you did not move the
.vdi file, then do not delete all files related to the
old machine.
This saved my day.
For me "Detachable Start" works, can you try it out?
I just went through exactly the same problem on a Windows VM. Uninstalling the Norton Internet Security and restarting my computer solved the problem. Credit to this article that I found here: https://forums.virtualbox.org/viewtopic.php?f=6&t=62615
