"It is wrong to suppose that if you can’t measure it, you can’t manage it—a costly myth." –W. Edwards Deming The Deming quote at the top of this post is often twisted into something worthy of Frederick Taylor: "if you can't measure it, you can't manage it." Deming would disagree.

Formats, linking, and versioning are important in well-formed RESTful APIs. In this series of posts on RESTful API design, we started from the spec of a bike rental application and we're moving towards a fully functional API design. In the first article , we talked about how to identify the URL and HTTP method pairs we would need to implement the server-side API for the application.

About a week ago I wrote about Ripple in a tutorial titled, Build a Ripple XRP Wallet for Android and iOS with Ionic Framework , which focused on mobile development as a followup to a cross-platform desktop application that I had written about before that. There are many who would advise against storing sensitive wallet information on a computer or anything connected to the internet.

The Working Set Size (WSS) is how much memory an application needs to keep working. Your app may have populated 100 Gbytes of main memory, but only uses 50 Mbytes each second to do its job. That's the working set size. It is used for capacity planning and scalability analysis. You may never have seen WSS measured by any tool (I haven't either). OSes usually show you virtual memory and resident memory, shown as the "VIRT" and "RES" columns in top.

I produced a decent amount of content in 2017. In fact, I wrote more blog posts than I have since 2013. Just not here. I wrote 17 posts for the Snyk blog and a handful of posts for other sites as well. I posted 889 tweets to Twitter. I reviewed 47 books on Goodreads. I’m probably forgetting some other things. But here, on my own site? Four. I wrote four posts.

The traditional daily stand-up meeting as generally practiced ranges from merely ineffective to a colossal waste of time. It's a band-aid that's hiding ineffective communication. First, some history. The 15-minute "stand-up meeting" is de rigueur for many Agile shops. It's been a standard practice from very early.

Charts are a great way to illustrate data within an application. No one likes trying to make sense of raw data or looking at it via a table. Instead a nice bar chart or line graph can paint a perfect picture of what’s going on. There are a lot of charting libraries available, but my personal favorite is Chart.js. It is a vanilla JavaScript library, so including it within a framework can be a little intimidating.

One of the best parts of my job is getting to talk to so many people from so many different companies about web performance. Every company is different, and I learn a ton from talking to each one. But one question that almost every person asks me – regardless of what industry they're in or the size of their organization – is this: How can I create a stronger culture of web performance at my company?

Software development is hard. Bugs and inaccurate time estimates are a fact of life. Software is too complex these days for things to go exactly as we’d like. However, developers often add to the difficulty of software development by doing certain things that make it harder than necessary. I know I have. One of these tendencies is associating less typing with saving time.

I spent a lot less time this year on social media. Mostly this was a conscious decision—the firehose that social media provides wasn’t doing my brain (or mood) any favors. So I dialed it back. At first, I had to trick myself, hiding my Twitter icon several pages deep on my phone so it was very inconvenient while making sure my Kindle app was up front and center.

"This isn't to say that alternative approaches to management are dead, or that they have no future. It is to say that in the absence of serious upheaval - the destabilization / disruption of established organizations, or the formation of countervailing power to the trends above - the alternatives to the Freds will thrive only on the margins (in pockets within organizations) and in the emerging (e.g., equity-funded tech start-up firms)." -- Me , September 2013 I wrote that nearly 5 years ago.

I’m a big fan, and hoarder, of Raspberry Pi devices. If you’ve seen my previous Raspberry Pi tutorials , you’ll know I like using them for hardware and software projects. These microcomputers use very little energy and have decent processors and memory, making them great for a diverse set of projects. With blockchain and cryptocurrencies on the rise, Raspberry Pi devices become great for getting familiar with concepts such as wallets, mining, and synchronized nodes.

Change is a constant for digital publishers. From Facebook reworking their News Feed (again) to show fewer posts from publishers to Google’s Speed Update including mobile load time in search rankings , the digital publishing industry has a lot to grapple with these days. Publishers don’t just need to worry about fake news, but also digital transformation and fierce competition for readers.

There was no deep goal — just a desire to see the maximum GFLOPS in action.

Explore the factors that make up a reactive microservice. One of the key principles in employing a Microservices-based Architecture is Divide and Conquer : the decomposition of the system into discrete and isolated subsystems communicating over well-defined protocols. Isolation is a prerequisite for resilience and elasticity and requires asynchronous communication boundaries between services to decouple them in: Continue reading What is a reactive microservice?

It was titled, Create a Cross-Platform Desktop Ripple XRP Wallet with Vue.js and Electron , and it focused on cross-platform desktop application development. A popular request on Twitter was around developing a mobile Android and iOS wallet for Ripple XRP coins.

I often say that one of my favorite quotes is: “There are developers with 30 years of experience and there are developers with 1 year of experience repeated 30 times.” This was said by a professor of mine who had 30 years of experience. It’s an important thought because some developers may have a lot of experience on paper, but they aren’t actually very good developers.

As photographers, we're always looking for the best way to carry our gear when traveling. Airplanes, especially smaller ones, are the most challenging for transporting photo equipment. Checking your cameras and lenses, even in a hard case, increases the risk of damage or theft. Most photographers prefer packing their delicate optics into carry-on bags, and leaving tripods, lighting equipment, and other more robust equipment in checked baggage.

Up until now, I’ve only been writing about interacting with different currencies. However, I haven’t discussed how to safely store your wallet information. When it comes to storing anything sensitive, whether it be cryptocurrency secrets or something else, you must do so safely and securely.
