edit (18.06.2015): Nowdays I’m using PM2, and here’s my post that explains how to use PM2.

Nodemon is a utility that will monitor for any changes in your source and automatically restart your server.  Install with npm:

npm install -g nodemon

Forever is a simple CLI tool for ensuring that a given script runs continuously (i.e. forever). Install with npm:

npm install -g forever

Forever & Nodemon running together:

forever start nodemon --exitcrash app.js

edit (24.02.2015):

If you get an error like this:

error:   Cannot start forever
error:   script /home/nikola/nodemon does not exist.

Try to run nodemon with the full path:

forever start /usr/bin/nodemon --exitcrash app.js

You can find out the path to nodemon by executing:

which nodemon

As you can see in the featured image, to find unread emails in Gmail, just search for is: unread and you will get all of your unread emails.

You can combine this, for example, to only find unread emails in a certain label: label:myStuff is:unread

I had to find some string inside one of the files, and I couldn’t remember in which file it was, classic 🙂

In linux, simple grep command would help, but on Windows there’s no such thing, or at least I thought… After some googling I came up with AstroGrep and I think it’s awesome, and it also comes with a GUI if you fancy that:

You can download it freely from their site.

Say you have a field called date in your MySQL table and its type is timestamp (example: ‘2014-08-23 08:37:57’), and you want to get all the records for today (so, all the records who’s dates are ‘2014-08-23’ neverminding the time). Here’s how yo do that:

SELECT * FROM `the_table` WHERE date(date) = curdate();

So, we’re using date() and curdate() functions here to help us achieve that.

Due to its folder nesting Windows can’t delete the folder as its name is too long. To solve this, install RimRaf:

npm install rimraf -g

and delete the node_modules folder easily with:

rimraf node_modules

edit: If you happen to get an “error” like this:

Don’t panic :), just try to run rimraf instead, as noted above. In most cases, all will be okay and you’ll be able to use it without a problem. If not, head to the comments, and we’ll take care of it together! For those who don’t care much about comments, here’s the post in which I address this node-inspector issue.

How to delete node_modules folder on Windows machine? http://t.co/0pV4OSTG1L #nodejs #windows #node_modules

Whenever I opened some pdf file and scrolled with the mouse the scrolling was per one page. Sure, you can change this by going to View -> Page Display -> Enable Scrolling:

but once you reopen Adobe Reader it’s back to as it was.

The solution is to make the default setting for all documents to have this setting and you do this by going to Edit -> Preferences and selecting Accessibility -> Override Page Display and setting it to Single Page Continuous.

edit: Thanks to Hugo André’s comment, it seems that in newer versions this is found by going to: “Go to the tab Adobe Reader -> Preferences”.

This has been haunting me for some time now – there’s just no Print Screen key on this keyboard which works on a Windows machine.

If you take a look at this thread you’ll see numerous attempts of which only installing AppleKeys2 worked for me. Now I only press F13 and woila – it works the same as Print Screen on a normal Windows keyboard.

If for some reason the link for AppleKeys2 is not working anymore, you can download it here.

So, if you have this in the code behind:

if (System.Windows.Forms.Screen.AllScreens.Length >= Config.ScreenNumber)
{
    System.Drawing.Rectangle screenBounds = System.Windows.Forms.Screen.AllScreens[Config.ScreenNumber - 1].Bounds;
    this.Left = screenBounds.Left;
    this.Top = screenBounds.Top;
}

And this in your XAML file on Window:

<Window WindowState="Maximized" ...

Asuming that Config.ScreenNumber equals 2, it will not position itself on the second screen no matter what you do, it will maximize on your main screen. What helped in the end was to remove the WindowState from the XAML definition and to add Loaded event handler:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    this.WindowState = WindowState.Maximized;
}

First you have to install NodeJS. You can do that via package manager for your distribution. In my case (RHEL) it is easily done with:

sudo yum install nodejs npm --enablerepo=epel

Installing CasperJS is easy via npm (Node package manager):

sudo npm install -g casperjs

You will get output similar to this:

To have the binaries in my path every time I log in I added this alias to my .bashrc:

alias phantomset="export PATH=$PATH:/usr/lib/node_modules/casperjs/node_modules/phantomjs/lib/phantom/bin/"

and my .bash_profile looks like this:

# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
phantomset

All of a sudden my arrow keys stopped working – up  and down keys scrolled the screen up and down, while left and right  had no effect. I found the solution here and basically all that you have to do is disable Scroll Lock on your keyboard! Pretty weird stuff, if I may add…
