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. On a Mac you need to in..

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....

Recently, when I tried to access http://slashdot.org/ in Firefox, I would see my browser title bar flash briefly to “AT&T GUI”, and then I would get redirected to: http://slashdot.org/ cgi-bin/redirect.ha which returns slashdot’s custom error 404 page! 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..

Black Friday” is the day after Thanksgiving in the United States. That's the day that most people are off work and starting to think about Christmas. 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..

One of the problems in cross platform development is availability of functionality on one platform that is missing on another. Case in point sending an SMS message. Android, Blackberry & J2ME support sending SMS’s in the background without showing the user anything. They even support a form of intercepting incoming SMS’s to one degree or another (but that’s rather problematic). iOS & Windows Phone just don’t have that ability, the best ..

Originally published on the AdRoll Blog on November 12, 2014 . The advertising industry has undeniably become a data play, as consumers are generating valuable data with every digital interaction. We hear buzzwords like “big data,” “machine learning” and “real-time algorithms,” but little about how these puzzle pieces fit together to help marketers achieve their business objectives. Over the last few years, the ad tech industry has lea....

Imagine you’re surfing through the web and all the pages show you the wait spinner for 15 seconds. How long would you continue to surf without losing your patience? How long until you move to doing something else? What if one website does this to you? Would you visit that page again without complaining? Would you recommend the website to anyone else?

As we wrote before our new Garbage Collector is designed for amazing speed and never locks, this worked really well for most cases but we started running into weird crashes that took us deep into the seemingly simple GC code and exposed a flaw in our “no locking” approach. It seems that our assumption that we can just mark all the static objects was flawed since a thread might mutate the static (global) object while the GC is ru..

Level design for days" has been my motto for several months now, and this week is no different. Behold, new challenge levels! These are timed, bite-sized maps with simple goals that can be completed in under a minute. They're the kind of things you can create in the level editor and share on Steam. I need to find a new texture for that garish green material. Lots of other things are happening, but they're more like a million ti..

Imagine yourself as a taxi driver, waiting at the front of a taxi rank for your next fare to who knows where. You've been in the business a long time and the city's streets feel like old friends. All of a sudden your rear passenger door opens and a new customer starts to climb into the back seat. The passenger starts with a question, "how much is it to the airport?" Your response is almost automatic these days, "about a hundred, give or tak..

At Thoughtworks, most of our projects begin with an inception where all the stakeholders in the project get together to analyse and start the discovery phase of the project. It’s usually done in order to develop a shared understanding about the project. There’s no working software to speak of, but we get a clear sense of why we want to build something.

Deploying your first Python-app can be tedious if you want to do everything by yourself. There are many great tutorials that help you set up all the necessary programs you’ll need to host your webapp. And trust me, it’s not easy: You’ll have to use a webserver that proxies the requests from your browser to a WSGI server . This in turn handles the communication with your app. You’ll also have to serve the static media like images, w....
