The key to making continuous integration work well is to ensure that the build stays green – ensuring that the team always knows that if something doesn’t work it was their change that broke it. However, in any environment with a build pipeline beyond a simple commit build, for example integration, acceptance or deployment tests, sometimes things will break. When that happens, there is always a natural tendency to commit an additional change that will fix it.

Here’s a fun one, we have some code generated using javassist that looks a bit like: public void doStuff(byte actionId) {<br /> switch (actionId) {<br /> case 0: doOneThing(); break;<br /> case 1: doSomethingElse(); break;<br /> default: <br /> throw new IllegalArgumentException("Unknown action: " + actionId);<br /> }<br />} This works perfectly fine on Java 6 and Java 7 but fails on Java 8. It turns out the problematic part is "Unknown action: " + actionId.

The truth is out: money is just an IOU, and the banks are rolling in it: What the Bank of England admitted this week is that none of this is really true. To quote from its own initial summary: “Rather than banks receiving deposits when households save and then lending them out, bank lending creates deposits” … “In normal times, the central bank does not fix the amount of money in circulation, nor is central bank money ‘multiplied up’ into more loans and deposits.

Esoteric Curio – 折伏 – as it relates to coding Our job as a team is to reinforce each other and make each other more productive. While I attempt to conquer some of the engineering tasks as well as legal tasks, and human resource tasks I face, I need concentration and it world certainly help to not be interrupted. I used to think I needed those times of required solitute pretty much all the time.

Geekdom is not a club; it’s a destination, open to anyone who wants to put in the time and effort to travel there… …dive headfirst into the things that interest you. Soak up every experience. Lose yourself in the pursuit of knowledge. When you finally come up for air, you’ll find that the long road to geekdom no longer stretches out before you. No one can deny you entry. You’re already home.

As a follow up to the earlier link regarding the performance of animations in CSS vs JavaScript, Christian Heilmann – Myth busting mythbusted: Jack is doing a great job arguing his point that CSS animations are not always better than JavaScript animations. The issue is that all this does is debunking a blanket statement that was flawed from the very beginning and distilled down to a sound bite. An argument like “CSS animations are better than JavaScript animations for performance” is not a technical argument.

Myth Busting: CSS Animations vs. JavaScript: As someone who’s fascinated (bordering on obsessed, actually) with animation and performance, I eagerly jumped on the CSS bandwagon. I didn’t get far, though, before I started uncovering a bunch of major problems that nobody was talking about. I was shocked. This article is meant to raise awareness about some of the more significant shortcomings of CSS-based animation so that you can avoid the headaches I encountered, and make a more informed decision about when to use JS and when to use CSS for animation.

The Guardian: Are iPads and tablets bad for young children? Kaufman strongly believes it is wrong to presume the same evils of tablets as televisions. “When scientists and paediatrician advocacy groups have talked about the danger of screen time for kids, they are lumping together all types of screen use. But most of the research is on TV. It seems misguided to assume that iPad apps are going to have the same effect.

If you’ve gotten used to your trackpad scrolling the same way as on iOS and (by default) OS X but you’re using Linux you’ll want to go to the “Mouse & Touchpad” settings panel and tick “Content sticks to fingers”. Yeah I know,shockingly simple but for whatever reason I had assumed “Content sticks to fingers” related to some weird drag and drop system…

This is mostly a note to myself, but often when I setup a new Linux install, I find that JUnit tests run significantly slower than usual. The CPU is nearly entirely idle and there’s almost no IO-wait making it hard to work out what’s going on. The problem is that JUnit (or something in our tests or test runner) is doing a DNS lookup on the machine’s hostname. That lookup should be really fast, but if you’re connected to a VPN it may search the remote DNS server which takes time and makes the tests take much longer than they should.

Chris Poole – Small things add up: By migrating to the new domain, end users now save roughly 100 KB upstream per page load, which at 500 million pageviews per month adds up to 46 terabytes per month in savings for our users. I find this unreal. Just by moving images to a domain that doesn’t have cookies. Impressive, especially given that users upload data significantly slower than they download it and HTTP 1.

Ron Qartel: Developing First Class Software with the Developers that Google Rejects Focus on building a great team and a great way to develop, not on hiring individual hotshots. I would caution however that XP isn’t necessarily the “great way to develop” that will work best for your team and your circumstances, but its certainly a good starting point. Just remember that the one key Agile principal is to continuously improve the way you work.
