Worth a watch:
Twitter, Disqus comments and over 1 million uniques!
Some smaller updates:
It's not something I follow that closely, but my blog has been read by more than 1 million unique people since its introduction! I plan to spend some more time blogging here in the upcoming time and I hope you stay tuned! Thanks for the support!
Messaging at Scale at Instagram
Has a lot of great insights and scaling strategies you might use. Recommended watching:
Simplicity Matters by Rich Hickey
Great and insightful talk by the Clojure creator:
Good enough is good enough!
An amazing talk by Alex Martelli, the "Über Tech Lead" for Google. It is from this year's PyCon 2013, it has nothing to do with Python tho'!
How to become more productive by using 2 computers
I have a simple and neat productivity tip I want to share.
One of the things I noticed I do a lot (especially when presented with hard problems) is to procrastinate by opening my email, opening Hacker News or something similar. I think it's a fairly common thing for most people. The problem with this is that it's very unproductive: because the mind gets distracted, looses focus and needs to do constant context switching. It's also ruins Flow, a state you want to be in:
There's a lot of scientific research on the matter that concludes that multi-tasking and constant context switching is really bad for your productivity.
Back to the tip! It's really simple:
I have found out that this improves my productivity greatly. You should try it out :-) Home officeI also recently setup a pretty awesome home office (I don't work here all the days of the week, but the days I work here it's amazing):
PyCon Russia - Redis, the hacker's database
I recently visited my first PyCon and held a talk about Redis, scaling and some libraries such as bitmapist!
The slide and video are already up:
Releasing bitmapist.cohort - or how we saved over $2000/month!![]() I released bitmapist a while ago and I am happy to release an extension that makes the library much more powerful! Installation and source codesudo pip install -U bitmapist The reason why I implemented thisI want to tell you why I coded this (and how we saved over $2000/month by having this library). I looked at Mixpanel's retention feature - which seems amazing. The problem for us is that we would need to track over 20million events pr. month and Mixpanel is crazy expensive (it would cost us over $2000/month to get this feature!) So I did what any sensible person would do: I coded my own version and open-sourced it so others can contribute. There's for example already a PHP port of bitmapist! What can it help me with?This library makes it possible to implement real-time, highly scalable analytics that can answer following questions:
If you want to read more about cohort please read following: Screenshot of bitmapist.cohortWith bitmapist.cohort you can get a form and a table rendering of the data you keep in bitmapist. If this sounds confusing look at Mixpanel. Here's a screenshot:
Getting startedMark user 123 as active and mark some other events: from bitmapist import mark_event
from bitmapist import cohort as bitmapist_cohort
mark_event('active', 123)
mark_event('song:add', 123)
mark_event('song:play', 123)
Generate the form that makes it easy to query the bitmapist database: html_form = bitmapist_cohort.render_html_form(
action_url='/_Cohort',
selections1=[ ('Are Active', 'active'), ],
selections2=[ ('Played song', 'song:play'), ],
time_group='days',
select1='active',
select2='song:play'
)
# action_url is the action URL of the FORM element
# selections1, selections2 specifies the events that the user can select in the form
# time_group can be `days`, `weeks` or `months`
# select1, select2 specifies the current selected events in the FORM
Get the data and render it via HTML: dates_data = bitmapist_cohort.get_dates_data(select1='active',
select2='song:play',
time_group='days',
system='default')
html_data = bitmapist_cohort.render_html_data(dates_data,
time_group='days')
# All the arguments should come from the FORM element (html_form)
# but to make things more clear I have filled them in directly
Plug the above code into your codebase and you are ready to go :-) Happy hacking! We are hiring talented iOS developers
