Over the years I’ve shared how to perform a number of actions with cURL: how to send POST data, how to retrieve headers, follow redirects, check GZIP encoding, and more. Another useful cURL directive is sending the user agent, as some servers respond with different content or headers depending on the user agent. Let’s have […]

The post How to Specify User Agent with cURL appeared first on David Walsh Blog.

Meanwhile, Subrata Biswas, principal secretary, department of agriculture and marketing, said they were ready for a legal explanation.

In the new series “Agent Carter” Marvel expands its universe to the small screen with help from Industrial Light & Magic. Creating high-quality visual effects was nothing new for the the award-winning team, but working against grueling weekly delivery dates proved to be a monstrous challenge. Mike Seymour finds out how they did it.

Elite Beat Agents is based off a Japanese video game for Nintendo DS. But instead of male cheerleaders and Japanese pop songs, the U.S. version relies on “Men In Black”-like agents and good ol’ fashioned American hits from the Jackson 5 and Madonna. Chris Kohler explains why the stateside edition is the best music game of all time.

We go behind the scenes to show you how visual effects company Double Negative created the dark energy Zero Matter in ABC's "Agent Carter."

Former FBI agent and body language expert Joe Navarro breaks down the various ways we communicate non-verbally. What does it mean when we fold our arms? Why do we interlace our fingers? Can a poker player actually hide their body language?

Former FBI agent and body language expert Joe Navarro breaks down the body language of well known mobsters. Why did Bugsy Siegel dress so sharply? What does it mean when Mickey Cohen pinches his nose? Why does John Dillinger sit with his arms crossed? Joe Navarro teaches us what all these non-verbals REALLY mean.

John Stewart, FBI agent and unit chief at the Hazardous Devices School, breaks down how bomb units in the police and military dispose of improvised explosive devices (IED) and other forms of ordnance. John explores the various disposal techniques used in the field, and explains how they keep themselves safe while investigating suspicious packages.

I was on the podcast A Question Of Code recently. It was fun! The podcast is aimed at people who are making a career change into web development, so it’s right up my alley.

I sometimes get asked about what a new starter should learn. On the podcast, I mentioned a post I wrote a while back with links to some great resources and tutorials. As I said then:

For web development, start with HTML, then CSS, then JavaScript (and don’t move on to JavaScript too quickly—really get to grips with HTML and CSS first).

That’s assuming you want to be a good well-rounded web developer. But it might be that you need to get a job as quickly as possible. In that case, my advice would be very different. I would advise you to learn React.

Believe me, I take no pleasure in giving that advice. But given the reality of what recruiters are looking for, knowing React is going to increase your chances of getting a job (something that’s reflected in the curricula of coding schools). And it’s always possible to work backwards from React to the more fundamental web technologies of HTML, CSS, and JavaScript. I hope.

Regardless of your initial route, what’s the next step? How do you go from starting out in web development to being a top-notch web developer?

I don’t consider myself to be a top-notch web developer (far from it), but I am very fortunate in that I’ve had the opportunity to work alongside some tippety-top-notch developers at Clearleft—Trys, Cassie, Danielle, Mark, Graham, Charlotte, Andy, and Natalie.

They—and other top-notch developers I’m fortunate to know—have something in common. They prioritise users. Sure, they’ll all have their favourite technologies and specialised areas, but they don’t lose sight of who they’re building for.

When you think about it, there’s quite a power imbalance between users and developers on the web. Users can—ideally—choose which web browser to use, and maybe make some preference changes if they know where to look, but that’s about it. Developers dictate everything else—the technology that a website will use, the sheer amount of code shipped over the network to the user, whether the site will be built in a fragile or a resilient way. Users are dependent on developers, but developers don’t always act in the best interests of users. It’s a classic example of the principle-agent problem:

The principal–agent problem, in political science and economics (also known as agency dilemma or the agency problem) occurs when one person or entity (the “agent”), is able to make decisions and/or take actions on behalf of, or that impact, another person or entity: the “principal”. This dilemma exists in circumstances where agents are motivated to act in their own best interests, which are contrary to those of their principals, and is an example of moral hazard.

A top-notch developer never forgets that they are an agent, and that the user is the principal.

But is it realistic to expect web developers to be so focused on user needs? After all, there’s a whole separate field of user experience design that specialises in this focus. It hardly seems practical to suggest that a top-notch developer needs to first become a good UX designer. There’s already plenty to focus on when it comes to just the technology side of front-end development.

So maybe this is too simplistic a way of defining the principle-agent relationship between users and developers:

user :: developer

There’s something that sits in between, mediating that relationship. It’s a piece of software that in the world of web standards is even referred to as a “user agent”: the web browser.

user :: web browser :: developer

So if making the leap to understanding users seems too much of a stretch, there’s an intermediate step. Get to know how web browsers work. As a web developer, if you know what web browsers “like” and “dislike”, you’re well on the way to making great user experiences. If you understand the pain points for browser when they’re parsing and rendering your code, you’ve got a pretty good proxy for understanding the pain points that your users are experiencing.
