This post is the first in a series on the difficult task of rounding a floating-point number to an integer. Laugh not! The easiest-looking questions can hide unforeseen difficulties, and the most widely accepted solutions can be wrong. This is part 0.99999999999999 of a series.

I started using a Samsung 550 Chromebook as my on-the-go machine two semesters ago. It worked nicely for taking notes, but I remained a skeptic: how could I ever write code from a glorified web browser? Fast forward 6 months: today, I love hacking on my Chromebook, and I have no problems working offline. It took some effort to get everything set up, so I’ve put together my recommendations to get other folks up to speed. Not for those of you who prefer IDEs - the main tools here are a terminal and web browser.

You have an idea for a program. It’s the best program idea you’ve ever had so you quickly prototype something in C... A work of genius. You quickly compile and run it to make sure all is good... Boom! But wait… What has happened? How has it gone from being quite an understandable high level program into being something that your processor can understand and run. Let’s go through what’s happening step by step. From compiling to cleaning up what you forgot to free(), and all the steps in between.

As told in a previous post, I like to watch the RDS-TMC traffic messages every now and then, just for fun. Even though I've never had a car. Actually I haven't done it for years now, but thought I'd share with you the joy of solving the enigma. RDS-TMC is used in car navigators to inform the driver about traffic jams, roadworks and urgent stuff like that. It's being broadcast on a subcarrier of a public radio FM transmission. It's encrypted in many countries, including mine, so that it could be monetized by selling the encryption keys. Cracking traffic message encryption is more fun than sitting in traffic.

The Jawbone UP fitness tracker is a lot more useful now that Jawbone has opened the API to third-party developers. One of the most exciting companies tapping into the UP platform is online automation tool, IFTTT. In the article below, I will talk a little bit about connecting your UP to IFTTT and then list some of my favorite recipes. Yes, there are APIs for network-connected fitness trackers. We live in the future.

I read scientific biographies hopeful that I might understand how they achieved scientific greatness, in order obviously, that I might emulate it. The outcome is, inevitably, that I better appreciate just how exceptional the individuals are and how unlikely any strategy dependent upon emulation might be. Only one practical lesson shines through, the requirement for a sustained and unblinking focus on a challenge that is worthy of the effort that must be devoted to it. Scientific greatness is earned, but it is also chosen. The habits of 11 highly brilliant people.

It’s a challenge to present deeply technical material to a room of people with varying expertise levels. If you leave it out, you’re abandoning the substance of your presentation. If you focus on it exclusively, you will lose most of the room. Expect to repeat yourselves two or even three times (but only one link here).

The elite of the tech world have decided that Google Glass is the future. And perhaps they're right, but, Google Glass is clearly not the present. It's not even the near-future, if the early reviews that are rolling in turn out to be accurate.... After reading all the reviews, and talking to people who actually wore Glass, I just see a product plagued by bugs, and of questionable use, that's generating a lot of buzz because people want so desperately to have some new gadget to latch onto, and fear being wrong about the next major technology trend. Reminder: mobile phones were once awkward, buggy and only used by jerks.

An idea that's guaranteed to take off. I think the buzz is definitely justified.

Stressing over your upcoming presentation where you have to type a bunch of code from memory or from a script? AutoHotKey can help you automate much of the “writing” of the code so you can write demos on the fly. AutoHotKey does so much more, but for a quick and simple way to write demos on the fly, it really is top-notch. If only all coding were as easy as this script.

“Slipping” or missing the intended completion or milestone date of software projects is as old as software itself. There’s a rich history of our industry tracking intended v. actual ship dates and speculating as to the length of the slip and the cause. Even with all this history, slipping is a complex and nuanced topic worth a bit of discussion about slipping as an engineering concept. Missed it by *that* much.

In the semiconductor world, integration is omnipresent, driven by Moore’s Law. Integration reduces power and cost while increasing performance. The latest realization of this trend is the System-on-a-Chip (SoC) approach pervasive among PCs, tablets, and smartphones. And the latest SoC is Haswell. Haswell is the first new family of SoCs from Intel to target the 22nm FinFET process, which uses a non-planar transistor that wraps around the gate on three sides. While Ivy Bridge was the first family of 22nm products, it was not fully optimized for the 22nm process. The CPU was a shrink of the 32nm Sandy Bridge rather than a new design. Optimized for a mobile future... finally.

If you want to know the most in-demand tech skills, that info is readily available. Want to learn the programming skills most coveted by employers? Done. But what are the skills and specialties that no one wants any more? What core competencies raise red flags instead of call backs? The only solution is to keep learning - and keep showing that you can learn.

Software Support and PC Support are on the list? 
I'm calling BS on that. The mighty cloud might be nice and shiny but every large office I know of still relies heavily on their PCs and desktop software.

Agreed, unfortunately there are a lot of idiots who spout idiotic things on the internet.

As is QA.
The smart phone and mobile market exploded, which is a different economy. Now, recruiter looks at his percentages and sees something. Some recruiters might want to reevaluate why we still feed people like them.
FWIW, the Austin Post article cited sounds quite different:
“[Employers] want people who are coding outside of work or committing to open source projects. Saying you’re ‘updating your skills’ means you’re working towards the goal of making money. That may be your goal, but employers don’t want to hear that. They want to hear you’re coding all the time because you love what you do.”

At Box, we’re very interested in the quality of our code, which is why we’re constantly evaluating our processes to figure out how we can do better. We even have a team of Code Reliability Engineers (CREs) that help others write better code and provide training both internally and externally. Recently, we’ve turned a critical eye towards code reviews and have been implementing a new process called code workshops. Code reviews are often terrible experiences. This idea may make them better.

The 2013 Linux Storage, Filesystem, and Memory Management Summit was held April 18 and 19 in San Francisco, California, immediately after the Linux Foundation's Collaboration Summit. This page will gather the coverage of this event, which was split into three separate tracks. The latest Linux discussions, all gathered in one place.

In NoSQL: Past, Present, Future Eric Brewer has a particularly fine section on explaining the often hard to understand ideas of BASE (Basically Available, Soft State, Eventually Consistent), ACID (Atomicity, Consistency, Isolation, Durability), CAP (Consistency Availability, Partition Tolerance), in terms of a pernicious long standing myth about the sanctity of consistency in banking. Myth: Money is important, so banks must use transactions to keep money safe and consistent, right? When availability is more important than consistency.

Clearly this is the policy of every government in the world.
