Global Average BMI value for both men and women
Global Average BMI value for both men and women

BMI Calories  is a small index off free health and fitness calculators mainly designed to be universally applicable for worldwide usage (each one has a metric system and a standard US measuring system).

The above picture is a screenshot of the interactive geo-chart-map, which displays the average BMI values in 177 countries for both men and women and can be found on the bmi calculator page.

Other calculators available on the site:

  • BMR calculator – for figuring out your basal metabolic rate (or resting metabolic rate, as it is sometimes referred to)
  • A Calorie intake calculator – for figuring out how many calories a day the body requires depending on the physical activity level you undergo. The nice thing about it is that it also has a section with a table of physical activities that span over ~300 or so different types of activities and their associated calorie consumption / expenditure values.
  • Body Fat percentage calculator – the name says it all, however what’s nice about it is that, aside from the actual body fat percentage value calculated, it also provides some insights into fat and lean mass,  body adiposity index (also known as BAI), and a value of the body fat extracted using the BMI – for adults and children alike.

Like with the interesting information from the global average BMI, all other calculators come with a plethora of additional information related to the actual calculation, which makes it a great resource for whenever you need to calculate these values, but also have some time to browse around. – Calculates the Best Time to Go to Sleep So You Wake Up Refreshed

Nginx Error – 413 Request Entity Too Large Fix

If you’re getting 413 Request Entity Too Large errors trying to upload files to your webserver, you need to increase the client body size limit in your nginx.conf configuration file.

Add ‘client_max_body_size xxM’ inside the server section, where xx is the size (in MB) that you want to allow for files upload to your webserver.

The client_max_body_size directive assigns the maximum accepted body size of client request, indicated by the line Content-Length in the header of request.

To edit your nginx configuration, in your terminal type the following:

sudo nano /etc/nginx/nginx.conf
sudo nano /usr/local/nginx/conf/nginx.conf
and set the
# set client body size to 2M #
client_max_body_size 2M;

as per the example below:

http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

server {
client_max_body_size 2M;
listen 80;
server_name localhost;

WordPress theme upload error “PCLZIP_ERR_BAD_FORMAT (-10)”

While trying to install a wordpress theme that was packaged as an .rar archive I got the following error:

The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

This is because I’m trying to unpack a .rar archive and the server doesn’t have rar archive support installed, however you can get around this issue quite easily.

All you need to do is unpack the .rar archive and re-pack it as a .zip archive and re-try the upload. Everything will work as expected after that.

Git – How to delete a local branch or remote

Git – delete a local branch:

git branch -d some_example_local_branch

Git – delete/remove a remote branch:

git push origin : some_example_remote_branch

In case of error after trying to remove remote branch, run:

git fetch -p

This is what the error message would look like:

error: unable to push to unqualified destination: some_example_remote_branch
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to '[email protected]_name'

and this is caused due to the fact that perhaps anyone else has already deleted the branch and you need to synchronize your branch list.
