This is the most insecure thing you can do to your linux system. That said however, when working on development systems at home I like to logon as SSH. Granted this is behind a firewall to a linux system with no access from the internet.
This was tested on Ubuntu 14.x on a Raspberry Pi.
I do this out of laziness. NEVER do this to an internet accessible system.

I often need to send text messages but my only way to send is via email. No worries. All carriers have a email version of your phone number that convert emails to texts. Here is how to figure out your email to text address:
- AT&T – email@example.com
- Verizon – firstname.lastname@example.org
- T-Mobile – email@example.com
- Sprint PCS – firstname.lastname@example.org
- Virgin Mobile – email@example.com
- US Cellular – firstname.lastname@example.org
- Nextel – email@example.com
- Boost – firstname.lastname@example.org
- Alltel – email@example.com
Cellular devices have many numbers associated with them, especially with respect to the SIM cards. Here’s a short list to keep them straight:
IMEI stands for International Mobile Station Equipment Identity and is used to identify 3GPP (also known as GSM (AT&T, TMobile, UMTS and LTE devices/networks) and iDEN mobile phones, as well as some satellite phones. It is usually found printed inside the battery compartment of the phone and often on the box the phone came in (think iPhone), but can also be displayed on-screen on most phones by entering *#06# on the dial pad, or alongside other system information in the settings menu on smartphone operating systems.
The IMEI is part of the phone, not the SIM card so swapping SIM cards won’t change the IMEI. (Kind of like a serial number)
ICCID stands for Integrated Circuit Card ID. This is the identifier of the actual SIM card itself – i.e. an identifier for the SIM chip. It is possible to change the information contained on a SIM (including the IMSI), but the identify of the SIM itself remains the same.
This allows you to swap SIM cards between phones and makes GSM style phones more convenient to use when you break your phone and want to swap it with a spare.
SIM stands for subscriber identification module and is basically the serial number of the card that you put in your GSM phone.
SIM cards come in many sizes, currently they are:
||ISO/IEC 7810:2003, ID-1
||ISO/IEC 7810:2003, ID-000
||ETSI TS 102 221 V9.0.0, Mini-UICC
||ETSI TS 102 221 V11.0.0
||JEDEC Design Guide 4.8, SON-8
UICC is the physical card most users refer to as a SIM. It stands for Universal Integrated Circuit Card. The SIM is a circuit component of this card.
Hope that helps. It’s shocking how the carrier customer service reps have no idea what any of this is an always ask you to read the longest number possible when they know full well the don’t need it….
This info will likely work for general linux as well, but my focus here is on the Pi. Continue reading “Auto running terminal applications (non GUI) on Raspberry PI”
I’m using the “official” Wi-Pi USB WiFi dongle and need to configure it. I’m going to do it via terminal over the wired ethernet port to start with. Continue reading “Configure WiFi on your Pi”
I got one of the cameras that use the port on the Pi. Here’s how to enable it:
raspi-config tool from your Terminal:
Enable camera and hit
Enter, then go to
Finish and you’ll be prompted to reboot.
You can refer to more documentation here on how to test and use it.
If you have encountered the error “This version of boot camp is not intended for this computer model” on a slightly older Intel Mac that does in fact run Windows 10, try the following:
- Launch CMD.exe as an administrator. You can do this by right-clicking on it and selecting RUN AS ADMINISTRATOR or left-clicking on it while holding CTRL+SHIFT to do the same.
- Change to your boot camp installation directory- in my case C:\users\administrator\desktop\bootcamp6\drivers\apple
- Execute the following command: msiexec /i bootcamp.msi
