I still have memories of playing this game in college backbenches. Never thought of developing this game until last week. It took me two days and just 400 lines of code to write the whole game using HTML Canvas and Javascript. My take on the first mobile game that I played.

ELDAM 1.4.0 released. With the new radical change in Elastic Search to drop mapping types, we had to do some changes to the ELDAM library. The add item API will now automatically create an index, if it doesn’t exist during commit phase. In 6.0 only one mapping can be defined for each index.

Lotus Image crop jQuery plugin. A plugin that you can use in your web page to visually crop an image. Once the user finishes his selection, we can retrieve the width, height, x position, y position and zoom values to crop the image using any of image processing libraries like pillow, imageJ, and Magick++ etc..
Code on GitHub: https://github.com/bemineni/lotus-imagecrop
$(".lotus-image-container").lotusImageCrop({'onchange': function(top,left,zoom,width,height){
$("#x-position").val(left.toString())
$("#y-position").val(top.toString())
$('#zoom').val(zoom)
}})
$("#increase").on('click',function(e){
$(".lotus-image-container").lotusImageCrop('increaseZoom')
e.preventDefault();
})
$("#decrease").on('click',function(e){
$(".lotus-image-container").lotusImageCrop('decreaseZoom')
e.preventDefault();
})
My first cooking blog of one of my favorite food Egg Fried Rice. I have seen many variations of making this dish. There is the authentic Chinese version, Spicy Indian version, Thai version with peanuts and Singapore version. This is my first attempt making the simple and easy Chinese version. Let’s start with the ingredients
Optional
Let’s start by making some scrambled eggs. Add some oil, break two eggs onto the frying pan, add some pepper and scramble the eggs. Transfer the scrambled eggs onto a plate.
Add some oil and fry the minced garlic.
Add onions fry until they are golden brown
Add carrots and capsicum and fry for some time
Add some salt to the vegetables, so that they don’t taste bland
Add green peas and fry until cooked
Add cooked rice
Add some black pepper
Add some soy sauce
Stir rice and all the ingredients until they are mixed well
Now add some fish sauce half a teaspoon.
Add some salt as needed. Caution – Both soy sauce(if salted) and fish sauce contain salt. Optional – Add two teaspoon of sesame oil.
Add scrambled eggs and stir well
We are almost done. Add some spring onions and stir well
We are done, serve the fried rice with some soy sauce or hot sauce
Please leave your comments if you have enjoyed making this dish.

git init .
We use the git URL in the form git:\\…
git clone git://github.com/bemineni/eldam.git
git add [filename];
The below command will add any new file that hasn’t been added to the current project
git add .
git status
-s Short output
git status -s
git diff
Show both staged and unstaged changes comparing with the head revision
git diff HEAD
To show the short status output of the diff
git diff --stat
git commit -m "Message"
This will open the default editor to enter the message.
git commit
Will get all the changes logs with respect to the branch
git log
A compact version of the log output.
git log --oneline
Will show a graph of the branches and changes
git log --oneline --graph
git reset HEAD [filename]
git rm
git mv
git tag -a
To get all the tags from the remote
git fetch origin --tags
To find out the current branch details use the below command
git branch
To find out last commits on all the branches.
git branch -v
git branch
The branch should have been created using the previous command
git checkout [name of new or existing branch]
The -b creates a new branch and switches to the new branch.
git checkout -b
git branch -d
This push the changes to the remote repository and delete the branch
git push [remote-name] :[branchname]
This command will merge the changes and move to the branch that was used to create this branch.
git merge
lists all of the remote repositories
git remote -v
Example:
$ git remote -v github git@github.com:bemineni/baamv.git (fetch) github git@github.com:bemineni/baamv.git (push)
git remote add [name] [url]
Example
$git remote add origin git@github.com:something/something.git
This command will remove the remote repositories
git remote rm [name]
Example
$git remote rm github
git remote rename [old_name] [new_name]
Example
$git remote rename github origin
git remote set-url
Example
git remote set-url github git@github.com:something/something.git
To synchronize your repository with a remote repository, fetching all the data it has into your branch reference locally for merging
git fetch git pull -> This will fetch from the remote and merge with the current branch locally
It will take what your [branch] looks like and push it to be [branch] on the remote, if possible. If someone else has pushed since you last fetched and merged, the Git server will deny your push until you are up to date.
git push
When you have changed on your working copy, from the command line do:
git stash
This will stash your current changes and clear your status
git pull
This will pull changes from an upstream branch. Make sure it says fast-forward in the report. If it doesn’t, you are probably doing an unintended merge
git stash pop
This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in the stash so you can start over if needed.
If you need to see what is in your stash
git stash list
We can now update and delete multiple document records using Elasticsearch query DSL and scripts. In this release below two new methods are included.
https://pypi.python.org/pypi/eldam/1.2.0
Documentation for this release at http://eldam.readthedocs.io/en/v1.2.0/
ElasticSearch Data Manager (eldam). eldam works with Zope transaction. You can add, delete or update documents all through your session. All data will be included in Elasticsearch database at the end when the transaction is committed. The module can be used in your web application to add/modify or delete elastic search data that will be committed along with other transaction data manager like zope.sqlalchemy. If any one of the transaction fails, then every Elasticsearch committed data will be reverted back. It’s like all go in or none. eldam implements two-phase commit as defined by the Zope transaction module. The module is well suited for a pyramid application.
https://pypi.python.org/pypi/eldam/1.0.1
pip install eldam
import transaction
from eldam.elasticdatamanager import ElasticDataManager
edm = ElasticDataManager()
edm.connect({
'elasticsearch_hosts':["16.83.62.232:9200","16.83.63.114:9200"]
} ,"test")
edm.add({'_type':'group',
'_id':'2',
'_source':{
"gid": 234,
"owner": "bemineni",
"name": "Sammy",
"grp_hash": "456678",
"description": "Sammy group"
}
})
transaction.commit()

We can generate a self-signed certificate using one simple command. This is fast and simple
izero@Ganesha ~/devel/demo $ openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout device.key -out device.crt Generating a 2048 bit RSA private key ..............................................................+++ ........+++ writing new private key to 'device.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [AU]:US State or Province Name (full name) [Some-State]:TX Locality Name (eg, city) []:Houston Organization Name (eg, company) [Internet Widgits Pty Ltd]:Lotus Inc Organizational Unit Name (eg, section) []:Lotus apps Common Name (e.g. server FQDN or YOUR name) []:iamzeroblog.wordpress.com Email Address []:srikanth.bemineni@gmail.com
What all did happen by executing this single command?
Now use your certificate(device.crt) and key(device.key) in your web server.

I want to start with some scenarios dealing with different people in your life.
Now think what you are going to do in all these situations?
There is varying level of emotions, feeling and personal loss that can result based on the righteous decision you make. In some situations the decision can affect your life very personally, In some it may be minimal, some times it may not affect you at all, you may also give suggestions on what is right thing to do at that time.
I feel we have varying degree of will to fight these demons in our mind to take the righteous decision. The situation may not always deal with some simple things mentioned above or with some ones life itself. The decision may with be with respect to materialistic gain or loss.
In the above questions, that last two situation is where our demons really kicks in. I feel if a person can really overcome this, then he is a pure soul who has conquered his demons. We can also at our subconscious level can tell where we are, and who is guiding our mind at this moment, is it the seven sins of evil or the path to righteousness . If we are with a person for long time, we can definitely tell what his decision would be , when these kind of situation occurs in his life.
Most of people including me move around this scale.
As this blog is written people in India are getting their new currency. I have been talking to some of my friends, seeing so many videos of people blaming the decision. Some people say common people should not be affected, some say government need to attack the big shots. From my perspective, every person in India from the multi millionaire to a street beggar is hiding some black money. Every one has some or significant amount of money that is not “reported” to the government. Looking up to the above questions, the situation falls under the last category. “My money is gone” for the mistakes that I have done to not disclose my money to the government. The crossed sentence is the whole statement which has the answer for the righteous decision. Lets see to how much extent the people of India are going to fight the demons to make the country a better place.
In my ten years of the programming experience, this is the most common programming bug that I always see in the code.
class A;
class B
{
public:
B(A* parent)
{
m_parent = parent;
}
void funcB()
{
delete m_parent;
}
public:
A* m_parent;
};
class A
{
A()
{
bptr = new B(this);
}
~A()
{
}
void funcA()
{
bptr->funcB();
}
void sayHi()
{
cout<<"Hi this is A"; } public: B* bptr; }; main() { A* aptr = new A(); aptr->funcA();
aptr->sayHi();
}
Some times these may be not be a straight forward bug like the one mentioned above. The difficulty is in finding when the Object was deleted. The best way is to put a break point at A’s destruct-or.
In Qt always try to use deleteLater to delete an object. Some times the object would have generated the event, and we should not be deleting the calling object from the slot or event processing handler. The best example I can give is during the socket disconnect event. The disconnect signal would be emitted on the socket closeEvent. If this event is handled by a slot in your program then , don’t delete the socket in the disconnected handler slot. Always use deleteLater(socket) to delete the socket object in the closeEvent handler. This will make sure that the socket object is deleted before the event loop starts processing the next event.
