headless ubuntu fsck waits for Y key during bootup

I have a headless Ubuntu 12.04 server in a datacenter 1500 miles away. Twice now on reboot the system decided it had to fsck. Unfortunately Ubuntu ran fsck in interactive mode, so I had to ask someone at my datacenter to go over, plug in a console, and press the Y key. How do I set it up so that fsck runs in non-interactive mode at boot time with the -y or -p (aka -a) flag?

For Ubuntu 15,16,17+ the FSCKFIX value setting is located in /lib/init/vars.sh

sudo nano /lib/init/vars.sh

change FSCKFIX=no to FSCKFIX=yes

How to fix USB flash, SD memory card, CD disc & Pen drive write-protected error?

We use removable storage devices a lot on a Windows computer, and some of you should at least once encounter the issue of the disk malfunction, which is mostly about “the disk is write protected”. When Windows starts to write protect your disk, for example, a SanDisk 4GB USB flash drive, you can no longer use it anymore until you remove the write protection. And the fix methods are as follows.

Method 1. diskpart command

Step 1. Open administrative Command Prompt.

Step 2. Type these commands one by one and press Enter key after each:

  • diskpart
  • list disk
  • select disk # (# is the number of USB drive with which you’re getting the write-protected error and is plugged in)
  • attributes disk clear readonly

Step 3. You may now close Command Prompt and re-plug the USB drive and check if the issue is resolved, by dragging a file to the drive or trying to format in Windows Disk Management or EaseUS Partition Master coming in the later part.

Invoke UI Changes Across Threads on VB .Net

I need to do this all the time and don’t have the best memory in the world. Today, I decided that I looked this up one too many times so here’s my solution to this multithreading problem:

The Problem:

You try to modify UI components created in one thread in another thread. In VB, you can only make UI changes on the same thread that created it so you get a nice “Cross thread operation not valid” exception.

Here’s the wrong code:

thread = New System.Threading.Thread(AddressOf DoStuff)
Private Sub DoStuff()
    'error occurs here'
    Me.Text = "Stuff"
End Sub

The Solution:

If you’re super lazy or you’re very sure of what your code is going to do, you can simply disable the exception with:

Private Sub DoStuff()
    Me.CheckForIllegalCrossThreadCalls = False
    Me.Text = "Stuff"
End Sub

This, of course, doesn’t prevent your code from making a mess. To do it properly, you need a delegate:

thread = New System.Threading.Thread(AddressOf DoStuff)
Private Delegate Sub DoStuffDelegate()
Private Sub DoStuff()
    If Me.InvokeRequired Then
        Me.Invoke(New DoStuffDelegate(AddressOf DoStuff))
        Me.Text = "Stuff"
    End If
End Sub

Wildly simple right?

To understand what the code does, you need to understand what Invoke() does. It can be confusing to google Invoke() because Delegates and Controls have different implementations of Invoke(). In this case, we’re calling Invoke on a subclass of Control. That causes the method on the second thread which is going through DoStuff() to run a method on the first thread (which created the UI element).

Now if you need parameters, here’s another example where “ReallyLongProcess” is a subroutine that raises an event “Done” with a parameter “success”

AddHandler Me.Done, AddressOf WorkFinished
thread = new System.Threading.Thread(AddressOf ReallyLongProcess)
Private Delegate Sub DoStuffDelegate(ByRef success as Boolean)
Private Sub DoStuff(ByRef success as Boolean)
    If Me.InvokeRequired Then
        Me.Invoke(New DoStuffDelegate(AddressOf DoStuff), success)
        If success Then
            'do stuff
            'do stuff
        End If
    End If
End Sub

        Me.CheckForIllegalCrossThreadCalls = False
            stp = ProgressBar1.Step * rnd.Next(-1, 2)
            newval = ProgressBar1.Value + stp
            If newval > ProgressBar1.Maximum Then
                newval = ProgressBar1.Maximum
            ElseIf newval < ProgressBar1.Minimum Then
                newval = ProgressBar1.Minimum
            End If

            ProgressBar1.Value = newval

    End Sub

Open Registry Editor. and navigate to the following Registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\MTCUVC

Next, in the right pane you will see a 32-bit DWORD value named EnableMtcUvc. In case you do not see it, create it. Its default value is 1. Change it to 0.
