Why I launched a consulting agency on open principles

Thursday 9th of March 2017 08:00:00 AM

For the vast majority of my career in the corporate world, I felt trapped in an environment that didn't work for me. The rules of that world seemed to contradict my core values—and I wasn't willing to compromise my integrity and core self for someone else to make a dollar.

How to set up a personal web server with a Raspberry Pi

Tuesday 7th of March 2017 08:03:00 AM

A personal web server is "the cloud," except you own and control it as opposed to a large corporation.

Owning a little cloud has a lot of benefits, including customization, free storage, free Internet services, a path into open source software, high-quality security, full control over your content, the ability to make quick changes, a place to experiment with code, and much more. Most of these benefits are immeasurable, but financially these benefits can save you over $100 per month.

How to make release notes count

Tuesday 7th of March 2017 08:01:00 AM

Congratulations! You're ready to ship the latest release of your software package. Now you need to make sure your release notes are in order. Sure, you could just slap "bug fixes and performance improvements" on the box and call it a day, but that doesn't really tell your users anything.

Working for a mission, not a boss

Tuesday 7th of March 2017 08:00:00 AM

I had a brilliant opportunity to interview Suresh V. Shankar, founder of Crayon, at Slush Singapore 2016. At the conference, he spoke about his experience—and the difficulties he faced—as an entrepreneur. He also talked about how he overcame them.

Suresh sold his previous company, RedPill Solutions, to IBM in 2009. However, his entrepreneurial journey did not end there. He went on to start a new company, Crayon, with the goal of simplifying big data.

Using proprietary services to develop open source software

Monday 6th of March 2017 08:03:00 AM

It is now pretty well accepted that open source is a superior way of producing software. Almost everyone is doing open source these days. In particular, the ability for users to look under the hood and make changes results in tools that are better adapted to their workflows. It reduces the cost and risk of finding yourself locked in with a vendor in an unbalanced relationship. It contributes to a virtuous circle of continuous improvement, blurring the lines between consumers and producers. It enables everyone to remix and invent new things. It adds up to the common human knowledge.

GNU Screen or tmux?

Monday 6th of March 2017 08:02:00 AM

If you've spent a fair amount of time working on the command line, chances are you've tried out a terminal multiplexer. These helpful tools let users easily switch between applications in the terminal, save sessions to come back to later, and manage connections to many machines at ones from one location.

Program LEGO Mindstorms robots over WiFi with BrickPi

Friday 3rd of March 2017 08:01:00 AM

For the past year, I've been teaching students how to build and program robots using the LEGO Mindstorms EV3 platform. From the outset, I wanted to find a way to use Scratch and other open source programming languages to extend the capabilities of the platform. That search led me to BrickPi, a Raspberry Pi add-on board from Dexter Industries that easily interfaces with Mindstorms sensors and motors.

  • Open-source developers targeted in sophisticated malware attack
    For the past few months, developers who publish their code on GitHub have been targeted in an attack campaign that uses a little-known but potent cyberespionage malware. The attacks started in January and consisted of malicious emails specifically crafted to attract the attention of developers, such as requests for help with development projects and offers of payment for custom programming jobs. The emails had .gz attachments that contained Word documents with malicious macro code attached. If allowed to execute, the macro code executed a PowerShell script that reached out to a remote server and downloaded a malware program known as Dimnie.
  • A scramble at Cisco exposes uncomfortable truths about U.S. cyber defense
    When WikiLeaks founder Julian Assange disclosed earlier this month that his anti-secrecy group had obtained CIA tools for hacking into technology products made by U.S. companies, security engineers at Cisco Systems (CSCO.O) swung into action. The Wikileaks documents described how the Central Intelligence Agency had learned more than a year ago how to exploit flaws in Cisco's widely used Internet switches, which direct electronic traffic, to enable eavesdropping. Senior Cisco managers immediately reassigned staff from other projects to figure out how the CIA hacking tricks worked, so they could help customers patch their systems and prevent criminal hackers or spies from using the same methods, three employees told Reuters on condition of anonymity.
  • NTPsec: a Secure, Hardened NTP Implementation
    Network time synchronization—aligning your computer's clock to the same Universal Coordinated Time (UTC) that everyone else is using—is both necessary and a hard problem. Many internet protocols rely on being able to exchange UTC timestamps accurate to small tolerances, but the clock crystal in your computer drifts (its frequency varies by temperature), so it needs occasional adjustments. That's where life gets complicated. Sure, you can get another computer to tell you what time it thinks it is, but if you don't know how long that packet took to get to you, the report isn't very useful. On top of that, its clock might be broken—or lying. To get anywhere, you need to exchange packets with several computers that allow you to compare your notion of UTC with theirs, estimate network delays, apply statistical cluster analysis to the resulting inputs to get a plausible approximation of real UTC, and then adjust your local clock to it. Generally speaking, you can get sustained accuracy to on the close order of 10 milliseconds this way, although asymmetrical routing delays can make it much worse if you're in a bad neighborhood of the internet.

    I assume that every permutation of scams will eventually be tried; it is interesting that the initial ones preyed on people's avarice and dishonesty: "I will transfer millions to your bank account, then you share with me" - with subsequent scams appealing to another demographic: "I want to donate a large sum to your religious charity" - to perhaps capture a more virtuous but still credulous lot. Where will it end ?
