Most post in this category are unfinished, imperfect, lack the polish a proper blog article should have, very often they have typos and even some time unfinished sentences. So why even bother? Well, because life isn’t perfect, and most imperfect. But it is important to get going anyway. It is important to persist. I know as I keep doing it it helps me shape my thinking. Mostly I avoid accumulating ideas in my head.

Click prediction may be a simple binary classification problem, but it requires a robust system architecture to function in production at scale. At AdRoll, we leverage the AWS ecosystem along with a suite of third party tools to build the predictors that power our pricing engine, BidIQ. This is a tour of the production pipelines and monitoring systems that keep BidIQ running. Introduction AdRoll participates on Real Time Bidding (RTB) ....

One of the main features in Java 10 in Local Type Inference, which allows us to substitute a type with the var reserved word in our source code. However, in order for this to become a feature that is useful to a developer rather than a feature developers will rue for many years to come, we need to learn how to use it and when to use it properly. This cheat sheet and blog is a reduced version of an blog post that Stuart Marks wrote on the Op..

My daughter loves dancing. She was entranced by this (so was I). The effort this must have taken to choreograph and the level of control between both the dancers is impressive.

In late 2016, I replaced my ISP router & modem combination – the BT SmartHub 6 – with separate bits of kit, to give me a little more freedom and something to occasionally tinker with. After a bit of research and bargain hunting, I ended up with: Modem – BT Openreach ECI VDSL 1b Router – Linksys WRT1200AC I originally picked up the WRT1200AC for its wireless speed & the ability to use opensource operating systems on it. I ran it from t..

The web is getting bigger. It is also getting slower. The funny thing is, every single day I’m visiting new sites to try out a new product or read a blog, and I find the same performance issues over and over again. All I have to do is check out DevTools to see that most images are way too large.

This talk is a code walkthrough, implementing a date picker to showcase the power of ember-changeset and contextual components. Given at the Ember Boston Community meetup. Ember-changeset is an addon that provides an abstraction over Ember models such that only valid data will ever be set in a model. Contextual components are a set of conventions that allow a developer to build a component that can be customized by its consuming applica..

SEO isn’t hard you need good content and good link. That’s kind of all. But when you cannot do any of these or you want to accelerate the process, might be worth thinking how you’re gonna optimise that process. Finding good content on this is pretty hard. This video however is really a neat finding. So enjoy !

This market is interesting now because I believe it’s at a juncture where we can choose one of two possible futures. We being the product builders, investors, and customers.

Every time you finish writing a blog post you get that feeling that it’s not ready to post it. It’s time for proofreading, but it’s painful to proofread your own writings. What is fun instead is reading someone else’s writings. So how great would it be if you could post your drafts somewhere, read and comment a couple of blog posts by people with your same interests, while your own get proofread by people like you?

Having multiple clients to handle multiple networks is a mess, especially the Slack client which is really heavy and annoying. Slack is deprecating its IRC gateway interface on May 15h 2018. Bitlbee is an IRC server working as a gateway to different IMs. Optionally Bitlbee can be compiled with LibPurple to support even more networks, like Slack and Hangouts. Here are some notes for Slack, Facebook and Hangouts to be enabled with Bitlbee.

I’m the chair this year for the first(!) ACM SIGPLAN International Workshop on Numerical Programming in Functional Languages (NPFL), which will be co-located with ICFP this September in St. Louis, Missouri, USA. Please consider submitting something! All you have to do is submit between half a page and a page describing your talk. There will … Continue reading Workshop on Numerical Programming in Functional Languages (NPFL)

There's this popular idea among developers that when you face a problem with code, you should get out a rubber duck and explain, to the duck, exactly how your code was supposed to work. Read more "Strange and maddening rules"

Something I always forget and have to search for is how to use Python to serve a directory for local testing and the like. Including it below so I have a copy I can always easily look it up. python -m SimpleHTTPServer 8090 and in Python 3 python3 -m http.server

This post covers the Langevin equation , a stochastic differential equation that models the dynamics of particles in Brownian motion 1 . This covers the ideas used in this reference due to Lennart Sjögren. Langevin Equation In 1907 Einstein published a paper that derived a macroscopic quantity $D$, the diffusion constant, with microscopic quantities : $$D = \frac{k_BT}{6\pi\eta a}$$ where $\eta$ is the viscosity of the liquid ....

Practice makes perfect. Or at least, it does help improve your skills. It does make you a better designer. A better problem solver. A better engineer. A better maker. Just better. Here are some resources to up your game. 1. Designercize Fancy designing a sortable list view for a habit-tracking app to help film snobs? Or how about designin dashboard for a smart home watering system, to help social media managers?

In class we recently discussed the simplified elastic rod model for polymers, which assumes that polymers can be modeled as an inextensible rod , i.e. that the length of the rod doesn't change, and that the twist of the polymer is ignorable (possibly because the polymer is joined by single bonds). I want to give a short proof of the statement that the tangent-tangent correlation function , i.e. the autocorrelation of the polymer at some d....

Expect tests are a technique I’ve written about before , but until recently, it’s been a little on the theoretical side. That’s because it’s been hard to take these ideas out for a spin due to lack of tooling outside of Jane Street’s walls.
