My Favorite Pomodoro App for Mac I bought this app because I struggle with ADHD and love the pomodoro technique for years I've been looking for a way to bring the cute and simple tomato timer to Mac/ the digital interface. I wanted a cute design with charts and tracking and this app has given me just that. Tomato is a Pomodoro timer for OS X. With Tomato you can easily manage your tasks and time them in a Pomodoro-like fashion. Adhering to the 25/5 minute cycle is key when using the Pomodoro technique. Tomato supports you by sitting in your status bar and timing the Pomodoro unobtrusively.
TTL (Time To Live) is a timer value included in packets sent over networks that tells the recipient how long to hold or use the packet before discarding and expiring the data (packet). TTL values are different for different Operating Systems. So, you can determine the OS based on the TTL value. You can get the TTL value by pinging an address. Here is the output got by pinging 'subinsb.com' on my system :
As you can see from the output, you got the TTL value. Since this website is hosted on a Red Hat system, it returned 57 which is close to 64 (TTL default value of Linux system). So, from this we can understand the OS of the remote system. Here are the default TTL values of different devices / Operating Systems :

I will update this table in the future when there's a release of new important OS whenever I get the time. You can get the short version of default TTL values by this table :
Tomato Mac Os Update
Device / OS | TTL |
*nix (Linux/Unix) | 64 |
Windows | 128 |
Solaris/AIX | 254 |
