If you think that while you are off an about on or off the ship the cabin steward and assistants are carefully cleaning your room and making towel animals, and that’s it, you are wrong. Unfortunately they also go through all your luggage and try to find anything they can take that you might not…

Recently taking a pen-testing course made me realize that security is such an important topic in software design, more so than I ever realized. Being a professional programmer for the last 15 years and attaining both undergraduate and graduate degrees in computer science helped me find only the basics of security. It took getting into…

We use self signed certificates at LeadSift for our dev and qa servers behind the firewall and have our team just import the certificate into their computers. Recently after months of it working just fine, I got an error on Google Chrome which looked like this. Attackers might be trying to steal your information from…

If you have duplicate entries in your /etc/groups or duplicates in general, in our case the same group in /etc/group that was also in ldap. So essentially “`getent group“` returns duplicates with different ids. The first entry will take…

At our company we had used hipchat for a little over 2 years, back when it was charging for when you had more than 5 users. I had previously tried to get the founders to try slack (since it was all the buzz) and failed. Since nothing was broken, I decided that hipchat was good…

TLDR; Gunicorn isn’t just “trendy” it actually works really well, in some cases (like mine) works much better than uWSGI. (also it seems that uwsgi is now becoming trendy, so am I just a hipster for switching to the uncool option :P) History I have always been a big fan of the uWSGI project. It has…
