Internet connection down? Make your mac talk to you when your internet (or other device) is back on line!

Usually is extremely annoying having to wait until your network connection is back after you had to reset your router, a power outage occured and you didnt had a battery on your network equipment, or maybe you rebooted a server or other device and are waiting for it to get back online. For all of you Mac users, I have a fun solution, make your mac give you a message when it comes back. Simply open up the terminal and type the following code: until ping -W1 -c1 google.com; do sleep 5; done && say We are back online! This will make your Mac speak that message to you when it receives a ping back from Google, meaning you should be ready to go back online. If you are waiting for other device to come back online, just change the address to ping as the following example: until ping -W1 -c1 192.168.1.32; do sleep 5; done && say the internet is back You will need to replace the IP address with the one you are waiting to get back online, you could even replace the I...

Different configuration settings on your router can be set to rehuse IP addresses with a certain frequency. Maybe you need to set your computer's IP static to be able to get to a service hosted inside your computer from anther device, or you are configuring any other software, knowing your IP might not be extremely straight forward.

Why is my MacBook fan so loud from boot?

I thought my Mac was getting old since the fan was creating a really loud noise, you could start hearing the fan since about five minutes after turning on my computer. So I did a little bit of digging and found the reason. First of all, In order to identify the process that is eating all of your CPU usage, to do this, we will use Activity Monitor, which comes installed in all  Mac OSX . To open the program, go to your Applications folder -> Utilities folder, and it should be at the top,  or do a simple Spotlight search (Command + space bar) and search for "Activity Monitor" Opening Activity Monitor, we should get a window like the one below, from here we can easily identify which is the process that is consuming the most of our resources and we can see if there is something we can do or not. In this example, we can see that the processes that are consuming the most CPU power are "fseventsd" and "launchhd" doing some quick internet research, I ...

View a Facebook locked profile picture

Facebook privacy is one of the most common topics we see in the news every couple of months, either that a new update on their policies is made or what not. Although in every update they try to fix every bug there is, this is sometimes impossible due to the fact that this "bugs" are actually functions that allow either the platform or other apps connected to Facebook to work properly. In on of this updates, Facebook added the feature to hide the full size profile picture from anyone except your friends, It is also possible to hide from friends if you switch the permission to "Only me". In this tutorial I'm going to show you how you can easily explode one of this bugs in order to gain access to locked profile pictures (and as a bonus get a full size image). 1.- First of all, you need to get the username of the profile you want to see the picture from, this username can be found in your address bar when viewing its profile page. 2.- Copy and p...

What do those weird mac keyboard symbols actually mean?

I bought my first mac around the last part of 2010, and till this day I haven't learned what those weird looking sings are, but lucky you, I did some research (maybe not enough but) here's what I found: The command key (or cmd in some keyboards) This is one of the keys that I use the most, also one of the ones that if I see the symbol ill recognize almost instantly (mainly because the symbol is printed into the key). This key is used as the control key in macs, so instead of making copy/paste like you will do in Windows (control + c/v), you use the keys 'command + c' to copy and 'command + v' to paste. There are a ton of functions that this key can be used for and some cool tricks, but Ill talk about that in another entry. Alt of Option key This key, although I use it regularly, is one key that I have trouble memorizing the symbol (contrary to the command key, the symbol is not printed in the key). One way you cold memorize the symb...
