So you have set up a test elastic beanstalk environment because you don’t want to put at risk your production elastic bean.
You don’t want to pay for the time you’re not using it, and there’s no freaking “Pause Environment” option.


all you can do is “Terminate Environment”? but then to crete the damn environment it takes forever to configure (if you’re using the dashboard), so we don’t want to do that.

If you try to terminate the associated EC2 instance, the Elastic Beanstalk environment will automatically provision a new machine for you, so that doesn’t work. What do you do?

Open the Elastic Bean environment you want to pause and go to “Configuration”

On the Scaling card, click on the Gear icon to change its settings

in the “Auto Scaling” options, set the “Minimum instance count” to 0, and the “Maximum instance count” to 0

Hit “Apply”

Wait for your environment to apply the new configuration

Now your health status has switched to gray. It’s now paused and you won’t be paying for the test ec2 instance while you’re not working on it.

If you are curious and you check the ec2 instances associated to the environment, it/them should be terminated now, but now the environment won’t try to provision new ones.

Savings in your pocket. Cheers.

Photoshop: How to Convert a Path into a Shape

So you wanted to create a Custom Shape on photoshop but you started drawing a path because of the nature of what you were doing (or because you forgot to change the pen mode to Shape) and now when you want to right click > “Define Custom Path…” it’s disabled in the menu.

Here’s the solution:

1. Select the path with the path selection tool.
2. Go to Layer > New Fill Layer > Solid Color. (Or use the Create new fill or adjustment layer button in the layers palette)
3. You have turned a path into a new shape layer.

How to resize a VirtualBox fixed size virtual drive (.vdi) on Mac

So you created a disk for your Windows or Linux VirtualBox VM and you made the mistake of not creating the drive as a dynamically expanding storage drive, you chose fixed size.

Now you’re running out of space and all your Google searches point you to stupid posts on the forums that lead to nowhere, specially if you are a MacOSX user, look no further, you’ve found the solution to your problem on this post.

VirtualBox for Mac comes with a tool called VBoxManage, this tool is all you need to resize your virtual disk.

When you’re using the VBoxManage tool make sure your VM is not running, stop it completely to be safe.

Step 0. Backup your current drive (optional)

I recommend that before you do anything you clone your existing drive, just in case…

You can clone your drive using guess what? yes, the VBoxManage tool. No need to download any external tools.

[bash]$ VboxManage clonehd <path to your original drive> <path of the copy>[/bash]

in my computer it looked exactly like this:

[bash]$ VBoxManage clonehd /Users/gubatron/VirtualBox VMs/windows7-64bit/windows7-64bit.vdi /Users/gubatron/windows7-64bit.cloned.vdi

If you don’t know where your .vdi file is, it’s very simple, right Click your VM > Settings > Storage, and mouse over the .vdi to see it’s physical location on your Mac hardrive.

Mouse over your virtual drive if you don’t know its location

Step 1. Resize!

The command to resize is:
[bash]$ VBoxManage modifyhd <path to your vdi> –resize <new size in megabytes>[/bash]

In my case I had a 20GB drive that I wanted to double in size (40GB), a quick Google search for “40GB to megabytes” yields the number 40960, so that’s what I put on my –resize parameter.

This is how it looked for me:
[bash]$ VBoxManage modifyhd /Users/gubatron/VirtualBox VMs/windows7-64bit/windows7-64bit.vdi –resize 40960

The ‘resizing’ is almost immediate.

Step 2. (Re)Start VirtualBox

After you’ve physically resized your drive, both VirtualBox and your OS should know about the changes.

At this point, clicking on your VM in the VirtualBox window will show that it still has the old size:

Before: (Note the size of the drive at the bottom of the image)

After doing the resize, shutdown completely your VirtualBox, and launch it again. When you see the information about the storage drives attached to your VM you should see the new disk size.

After: (Note the size of the drive at the bottom of the image)

Step 3. Let your OS know the new logical size of the drive

Your OS is still not aware of the changes, you need to let it know about them

When you start your VM, it won’t know right away what the new size of the disk is, you’ll have let the operating system know that there is additional space it can use.

If your VM is running Windows 7, the way to let the operating system know that it can use the additional space on your drive is very straight forward.

Click on the Windows (Start) Icon on the Bar > Right Click on “Computer” > Manage (You’ll need to be an Administrator)

The “Computer Management” window will open, in it go to:

Storage > Disk Management > Right Click on the partition you want to extend.

Select the option that says “Extend”, a Wizard will open, just hit Next until it ends if you want to use the whole space.

After you’re done, if you refresh your “Computer” on the File explorer the resized drive should show right away

That’s it, enjoy and let me know how it went.
