Data (eyes) says it all!

I have been bitten by the"what does data say?" bug these days.

I love to find out and understand the trends these days through the eye of data ( professional hazard)


Here are come very interesting articles I cam across to understand the things that baffle me.


Brexit (today's hottest topic and am sure for many more days to come)

I will keep adding here interesting trend explained by data :)

web application firewall vendors comparision

I plan to put our more articles regarding WAF (web application firewall).
But for now if you already know what WAF is and you are evaluating WAF vendors this post should help.
The are the top WAF vendors as per Gartner

But it's hard to compare the features etc. of the vendors without a compressed chart.


NSS Labs have evaluated different vendors extensively
Individual reports of their analysis can be found here in the test reports section for NSS Clients :-

More detailed analysis can be found here :-

Much more details (not on vendors though)  on WAF :-

Mentor with your tech skills : here are few choices and my experience.

I have been volunteering on and off in past few years.
Here are the avenues I have had in the past,  to share my expertise and skills:-
1) Google summer of code
2) Google Code-in
3) In coppell-ISD schools for Engineering week, Sharktank, Science fair,  IBM gigawatt camp e.t.c
4) getMAGIC


I have been volunteering for many other organisations as well like Vibha, AID (Association for India's development), Systers but today I want to talk about the opportunities where I was able to share my technical skills and learn and grow in the process.

My IBM-ISD mentoring sessions have been mostly event based but I totally love to get into the class meet the students in person and get infected by their enthusiasm and innocence.

My GSOC( google summer of code)  and GCI (google code in) has been equally enjoyable but in some sense it's been a little different. I don't get to meet my students but we work together like we would in a office setting but we work towards a humanitarian open source project..which is what makes it soo cool! Not only are you mentoring .. your work is actually being used for a good cause!!!
These are time-lined volunteering assignments ( in summer vacation or winter vacation for students) and everything is do-able remotely ( which is super convenient). I love the humanitarian opensource aspect of this soo much that this year I am organizing (actually co-chairing)  the Grace Hopper Conference Open Source Day ( GHC-OSD-2016).

My Magic mentor has been a very exquisite one. I got assigned a student in bay area and I started meeting her weekly (remotely over skype or gchat) and we made a personal connection. My assumption were soon shattered since she proved out to be a very mature, tech-savvy, hands-on little lady who did not need the "get-started" links for programming. She already had done a arduino project and this time we wanted to do a more advance complex and artistic project. We went ahead on that journey and how much a learned about this new generation of technology at their tips is incredible!!
I am looking forward to meeting her and helping her with her final presentation on magic project (and I guess I will updated the post once I am done with that)

I highly encourage all of you to consider volunteering your tech skills as a mentor .. it's always an amazing experience. Choose based on the time commitments you can make and your passions and interest .. but do choose one!!

If you're also a woman in tech/STEM, and have considered volunteering, please feel free to ask me and don't hesitate to reach out to me with anything i can help you .. if we share the same passion then also lets get in touch :) would love to hear from you.

Push your package to pip

Finally after a long time .. a PR on my git project  https://github.com/Neetuj/python-wns
reminded me that i still need to push it to pip.

Given the hits I get on my notification entry (most popular so far) push-notifications-on-apns-gcm-WNS 
I felt bad for not putting in the effort before to push python-wns to pip
Anyways I finally did it today and now you all can avail the power of pip for python-wns by

pip install python-wns

Now if you are the one who are not interested in my pyton-wns package but want to push your own package here are the steps I followed  (order can be important so follow it :)

• Register on https://testpypi.python.org/pypi
• Register on https://pypi.python.org/pypi
• Confirm all verification emails for the new accounts 
• create a .pypirc file "vim ~/.pypirc" which looks like this 
• [distutils]
  index-servers =
    pypi
    test
  
  [pypi]
  repository=https://pypi.python.org/pypi
  username=name
  password=pwd
  
  [test]
  repository=https://testpypi.python.org/pypi
  username=name
  password=pwd
• package your library like this  

• python-wns/
    setup.py
    setup.cfg
    LICENSE.txt
    README.md
    wns/
      __init__.py

      wnslib.py 

   
•  The setup.py needs to be in a certain format you can checkout mine here setup.py
• Then test 
•  python setup.py register -r test
•  proceed if you get Server response (200): OK
• python setup.py sdist upload -r test
• proceed if you get Server response (200): OK
• python setup.py register sdist upload
• and you are done!!  test "pip install python-wns"

Debugging openstack ....logs , services e.t.c

Something is broken ...
lets say heat is not starting up ..
what do we do ?

calm down!
check logs ( /var/log/heat-api.log,  /var/log/heat-api-cfn.log, /var/log/heat-engine.log)

Do you see any errors there ?? ( most of the times this should be sufficient)

but what if there is not error in the logs.. since the service is not even starting ?
try restarting the service(systemctl comes to rescue)

systemctl list-units |grep heat

systemctl status openstack-heat-api.service

systemctl status openstack-heat-api-cfn.service

systemctl status openstack-heat-engine.service

Just getting a failed status but no details ?try debugging

journalctl -u openstack-heat-api-cfn.service

here are few links which will help
