Welcome to the Era of Living Cell Programming

I was reading Understanding mRNA COVID-19 Vaccines by the United States Centers of Disease Control and Prevention when it stunned me that living cell can be programmed in vivo. mRNA COVID-19 vaccines are produced by Pfizer and Moderna. I already knew what Ribonucleic acid (RNA) is. RNA is almost a half part of DNA the super-intelligent organic codes that manifest us. But I didn't know that they can produce messenger RNA (mRNA) which can instruct cells to do whatever they wanted.

This is my understanding so far. mRNA vaccines instruct our cells to make a protein and then triggers antibodies to kill the protein. In the case of mRNA COVID-19 vaccines it will instruct our cells to make a part of the virus proteins which is harmless to our body but sufficient enough to trigger the antibodies. Later when the real virus enters our body the trained antibodies will kill it.

mRNA is a new kind of medicinal system. An mRNA can be sequenced or programmed to instruct a cell to make all sort of things like producing drug compounds or other organic compounds. A cell is like a computer and an RNA is the software. The mRNA system is better than the so-called nano-computer or nano-robot, or bio-chip because it is non-intrusive and looks just like a part of the living system.

The race is now on to encode mRNA for any purposes. This is the subject of in-silico genetic engineering, computer-aided drug discovery and design (CADD), and computational molecular physics. It involves big data, Artificial Intelligence (AI) and supercomputers. The entropy has just begun. 

How about the dark side? Can mRNA turns a cell into a bad actor? In real life all viruses have RNA. It is ironic that we now use mRNA to kill viruses. Hopefully, the system will not fall into the hands of naughty scientists who will code the mRNA with more instructions than it is intended to be. A lot of codes can be packed in a single strand of mRNA.

Setting Up PyScripter for Quantum GIS

PyScripter is a general purpose Python Integrated Development Environment (IDE). Quantum GIS (QGIS) is a desktop GIS application that can be extended with Python plugins. Both are open source softwares. We intend to use PyScripter as an IDE to build QGIS Python plugin. We are using PyScripter 2.4.1.0 and QGIS 1.6.0 in Windows. PyScripter does not come with Python. On the other hand, QGIS is built in with Python. Thus, we will setup up PyScripter to use the build in Python in QGIS. We assume both PyScripter and QGIS are already installed. Preparing PyScripter batch file We assume that QGIS is installed in C:\OSGeo4W\ folder and PyScripter is installed in C:\Program Files\PyScripter\ . 1. Copy qgis.bat in C:\OSGeo4W\ bin to pyscripter.bat 2. Edit pyscripter.bat to remove the last line that read something like this start "Quantum GIS" /B "%OSGEO4W_ROOT%"\apps\qgis\bin\qgis.exe %* and replace it with this in one line Start "PyScripter" /B "C:\Progr

Sending Emails via SMTP

msmtp  requires a minimal setup for sending emails via SMTP compared to sendmail. Here is a configuration for you to send emails from a web host to an external SMTP server. Prior to doing that, you must check whether there is a clear communication channel between your web host and the SMTP server. You can use Telnet . Set up msmtp You are going to set msmtp as an MTA . Hence, you need to remove all other MTAs such as postfix and sendmail: $ sudo apt-get --purge autoremove postfix sendmail Install msmtp and related utilities: $ sudo apt-get install msmtp msmtp-mta mailutils Configure msmtp: $ sudo nano /etc/msmtprc # Set default values for all following accounts. defaults # Use the mail submission port 587 instead of the SMTP port 25. port 587 # Always use TLS. tls on # Set a list of trusted CAs for TLS. The default is to use system settings, but # you can select your own file. tls_trust_file /etc/ssl/certs/ca-certificates.crt # The SMTP server account mx host mail.mx.example

fatal: Couldn't find remote ref master

If you are using Github then  master is now known as main . Whatever you want to do with a master must now be referred to a main . If you search for this error message on the Internet then you will encounter with a lot of old discussions on how to set up your master properly which is probably not what you are looking for. The master  is your problem. Rename it to main . I wrote Git My Way about two years ago. Today I created another Github repository. I got this  "fatal: Couldn't find remote ref master"  error message when I wanted to sync the new repo for the first time with my notebook using the notes I wrote in the blog. All the discussions around the error message I found on the Internet were perplexing. Then I recalled that Github had renamed master to main  due to the master-slave connotation. We always have a master copy of a code, never a slave copy. Now suddenly a word context has been diminished for good. What is going to happen to the existing vast documen
