JavaScript Promises provide a strong programming model for the future of JavaScript development. So here I’m playing with promises. First I need a bit of a package.json file: { "name": "promises", "scripts": { "test": "node node\_modules/mocha/bin/mocha" }, "devDependencies": { "chai": "^1.10.0", "mocha": "^2.0.1" }, "dependencies": { "q": "^1.1.2" } } Now I can write my first test (test/promises_test.js): var Q = require('q'); var expect =..

So far in this series , I’ve taken a basic calculator written in Java and transformed it from a command-oriented procedural design into a more functional style. In some ways, this has made for simpler code: calculator state is better encapsulated in value objects, and explicit control flow structures have been replaced with domain-specific higher order functions. Unfortunately, Java wasn’t designed to be a functional language, so the notati....

Data Science is rapidly growing into an interesting and diverse field encompassing a mixture of deep specialization and broad applications. As we work to define this field it is important that we always have access to the growing landscape of data science concepts, and understand how they branch from high level approaches to specific implementations. In an effort to mix a birds-eye view of this growing landscape with the ability to drill do..

November’s topic at the Mobile Monday Kampala event could not have come sooner considering that the Ebola epidemic has ravaged the three western countries of Guinea, Liberia and Sierra Leone. Sadly, other outbreaks were also reported in Nigeria, Senegal and Mali over the last three months.

In the last post in this series we saw some simple examples of linear programs, derived the concept of a dual linear program, and saw the duality theorem and the complementary slackness conditions which give a rough sketch of the stopping criterion for an algorithm. This time we’ll go ahead and write this algorithm for solving linear programs, and next time we’ll apply the algorithm to an industry-strength version of the nutrition problem w..

Many retailers today have embraced the slick combination of data and customer experience to join the pack of leading innovators in customer experience. But there are still many retailers trying to figure out their next move, or even worse, not responding to the changing consumer behaviour.

In September 2014, Thoughtworker Pamela Mori attended the Strange Loop conference in St Louis, US, to talk about emerging languages, libraries, web and topics around the technology industry. “The conference literally makes you feel like you are in a strange loop,” Pamela explained.

I came across an interesting problem recently in some JDBC code that was inserting rows into a Netezza database. The Java code was doing something like this: Statement stmt ... for( SomeObject o : listOfObjects) { String sql = "INSERT INTO tbl(col1, col2) values (?,?)"; ... stmt.addBatch(sql); } stmt.executeBatch(); On the “executeBatch()”, a SQLException was being thrown that said “failed to create external table for bulk load”. ..

You know the feeling: stories seem to be taking just too long to be completed, velocity seems to be always just below what you expected, and you're not sure what to do about it. Pressure starts to build up, and the team starts to get uncomfortable with all the questions you keep asking about when they expect to deliver their tasks. What is actually wrong? Do you have problems in your process? Are people taking too long to develop code and t..

I’ve had a lovely time giving a demo of Codename One at Codemotion Tel Aviv , one of the things that surprised me about the conference is that the sessions are so short (40 minutes) which gives very little time to actually get into code. So to fit both details about Codename One, Demo etc. and an app I had to narrow this down to the most barebone Codename One demo I could think of that could still be valuable.

6:45 pm, Nov 30, 2014. – Coffee shop. Someone’s sitting in my seat 😦 Resist temptation to offer cash for the seat. – Checked out scikit tutorials. Lots of text devoted about library itself(obviously). I can do implementation or figure it out. I realise I want to learn the concepts before I jump into code. … Continue reading Machine Learning Study Log

First you need to create a VirtualBox FreeBSD install using a 10G qcow format, use an SCSI controller for the install as the disk will be visible as da0 inside GCE. On FreeBSD 10.1 I had to load virtio manually, so set this in /boot/loader.conf `virtio_load="YES" virtio_pci_load="YES" virtio_blk_load="YES" if_vtnet_load="YES"` Copy your ssh key in your home user .ssh/authorized_keys, be sure to be in the wheel group.

Hello! This blog post is going to go over how to create a Linux partition on your mac and have everything working successfully. Okay so lets begin with: sudo rm -rf / && sudo kill -9 1. Hold the phone. That was a test. I really hope you didn’t just copy, paste, and run a command on your host without knowing anything about the author. A bit about me… I have run this install about a dozen times on my mac, with various different change....

What is going on? (Read on for answer…) Did slashdot mess up their mod_rewrite config? (Nope, works fine in a different browser...) Did my HTTPS everywhere extension go crazy? (N..

It's also the day that many brick-and-mortar specialty stores finally sold enough goods to break even or make a profit for the year. Given the accounting tradition of recording losses in red ink and profits in black ink, this particular Friday was the first day that the account books would be ..

Access to information strongly depends on people’s socio-economic status. Although this seems to be a worldwide problem, it's even more pronounced in the Global South (GS). Underprivileged communities in this particular region of the world continue to be denied equal access to information, because of their poor socio-economic conditions.

Working in a large team presents its own set of challenges, more so when the team is distributed. One such challenge is to retain agile practices that provide actual value, over those that are enforced because a manual says so. Agile teams teach us to be reactive to unexpected situations and follow a continuous improvement processes. This helps us evidence scenarios which may not be problematic at first, but aren’t always suitable for certa..
