WriteFreely: Start a blog, build a community

ven, 02/22/2019 - 09:02

As more of our lives move online, we become dependent on large services with millions (or billions) of users to communicate with each other. Although we tend to notice problems only when these platforms change a policy, erect a paywall, or suffer a data breach, we can often feel how these mass-broadcast platforms don't always have our best interests in mind and often don't "connect" us in the ways they purport to.

Developer happiness: What you need to know

ven, 02/22/2019 - 09:00

A person needs the right tools for the job. There's nothing as frustrating as getting halfway through a car repair, for instance, only to discover you don't have the specialized tool you need to complete the job. The same concept applies to developers: you need the tools to do what you are best at, without disrupting your workflow with compliance and security needs, so you can produce code faster.

Natural disasters on the rise: How open data and tools can save lives

jeu, 02/21/2019 - 09:03

If you've lived through a major, natural disaster, you know that during the first few days you'll probably have to rely on a mental map, instead of using a smartphone as an extension of your brain. Where's the closest hospital with disaster care? What about shelters? Gas stations? And how many soft story buildings—with their propensity to collapse—will you have to zig-zag around to get there?

Infrastructure monitoring: Defense against surprise downtime

mer, 02/20/2019 - 09:01

Infrastructure monitoring is an integral part of infrastructure management. It is an IT manager's first line of defense against surprise downtime. Severe issues can inject considerable downtime to live infrastructure, sometimes causing heavy loss of money and material.

Monitoring collects time-series data from your infrastructure so it can be analyzed to predict upcoming issues with the infrastructure and its underlying components. This gives the IT manager or support staff time to prepare and apply a resolution before a problem occurs.

A good monitoring system provides:

Do Linux distributions still matter with containers?

mer, 02/20/2019 - 09:00

Some people say Linux distributions no longer matter with containers. Alternative approaches, like distroless and scratch containers, seem to be all the rage. It appears we are considering and making technology decisions based more on fashion sense and immediate emotional gratification than thinking through the secondary effects of our choices. We should be asking questions like: How will these choices affect maintenance six months down the road? What are the engineering tradeoffs? How does this paradigm shift affect our build systems at scale?

3 tools for viewing files at the command line

mar, 02/19/2019 - 09:01

I always say you don't need to use the command line to use Linux effectively—I know many Linux users who never crack open a terminal window and are quite happy. However, even though I don't consider myself a techie, I spend about 20% of my computing time at the command line, manipulating files, processing text, and using utilities.

One thing I often do in a terminal window is viewing files, whether text or word processor files. Sometimes it's just easier to use a command line utility than to fire up a text editor or a word processor.

Make websites more readable with a shell script

ven, 02/15/2019 - 09:02

If you want people to find your website useful, they need to be able to read it. The colors you choose for your text can affect the readability of your site. Unfortunately, a popular trend in web design is to use low-contrast colors when printing text, such as gray text on a white background. Maybe that looks really cool to the web designer, but it is really hard for many of us to read.

Why should you use Rust in WebAssembly?

ven, 02/15/2019 - 09:01

WebAssembly (Wasm) is a technology that has the chance to reshape how we build apps for the browser. Not only will it allow us to build whole new classes of web applications, but it will also allow us to make existing apps written in JavaScript even more performant. 

In this article about the state of the Rust and Wasm ecosystem, I'll try to explain why Rust is the language that can unlock the true potential of WebAssembly.
