With the enormous attack surface of cloud providers like AWS, Azure, and GCP, why aren't there more security problems? Data breaches and cyber attacks occur daily. How do you explain the unreasonable effectiveness of cloud security? Google has an ebook on their security approach; Microsoft has some web pages. Both are the equivalent of that person who is disgustingly healthy and you ask them how they do it and they say "I don't know.

Guest Post by Wendy Dessler. Source- Pixabay. When trying to develop a new piece of software or an app, one of the first things a developer has to do is pick a programming language. For years, the debate has raged on regarding which programming language is better, Java or Scala. While some argue that just because Java is older it is better, others believe Scala is better for a variety of reasons.

Exploring use cases for the two tools. This episode of the O’Reilly Podcast, features a conversation on serverless and Kubernetes, with Kelsey Hightower , developer advocate for Google Cloud Platform at Google (and co-author of Kubernetes: Up and Running ), and Chris Gaun , Kubernetes product manager at Mesosphere. Discussion points: Hightower and Gaun agree that the biggest issue people face when deciding to start using Kubernetes is an underestimation of the learning curve.

In America, it is generally considered taboo to discuss salaries. Some of this is surely rooted in socially normative behavior, where discussions of personal finances are considered conversation’s most intimate tier. Some of it probably comes from that stigma being cemented into the “professional identity” expected of employees. (Some companies have even gone so far as to make open salary discussions a dismissible offense !

TL;DR : we cannot continue to use as much JavaScript as is now “normal” and expect the web to flourish. At the same time, most developers experience no constraint on their use of JS…until it’s too late. “JS neutral” (or negative) tools are here, but we’re stuck in a rhetorical rut. We need to reset our conversation about “developer experience” to factor in the asymmetric cost of JS.

The other week, there were a few articles that came out about Chrome’s NOSCRIPT intervention: an intervention that would disable JavaScript altogether on slow networks. Chrome intervening on behalf of the user when it feels the network is iffy isn’t exactly new. Chrome has several interventions including one that can replace images with placeholders and one that bypasses web fonts on slow connections.

Now, 10 years later a faster, stronger, and more reliable version of TLS has been released. Today we’re very excited to announce that KeyCDN has officially launched TLS 1.3 support for all customers. This brings with it some exciting benefits which we will discuss throughout this article.

Most modern web applications need to be able to handle data consumption requests and data manipulation requests from clients using HTTP. It is the norm to pass JSON data between these requests so it makes sense to use a NoSQL document database because JSON and similar is the common storage format, eliminating the need to marshal data to new formats in every request.

Many people ask what the difference between Alpha and Beta testing is? Both have important parts to play in bringing new or improved software to market. While the questions they ask serve different purposes, they are both forms of acceptance testing. Alpha and Beta testing differ in a number of ways, not least with the stage in development when they are implemented.

Chrome Extensions have been around for a long time. I believe they are a very under-explored technology - and if you’re a traditional web developer, there’s a very small learning curve since Chrome Extensions are comprised of HTML, JavaScript and CSS. Bonus - you don’t have to worry about every browser under the sun, just Chrome! (though Firefox is becoming extension-friendly, it might be a good idea to not include Chrome-only web features).

There’s something deeply ingrained in many developers, including myself, that creates a tendency to over-engineer. Maybe it’s how we’re taught or maybe it’s a natural desire to “future proof” our code. Regardless, this tendency is so strong that even being aware of it is not enough to prevent the behavior. Earlier this year, I was working on a system for helping users filter their emails.

MySQL has locking capabilities, for example table and row level locking, and such locks are needed to control data integrity in multi-user concurrency. Deadlocks—where two or more transactions are waiting for one another to give up locks before the transactions can proceed successfully—are an unwanted situation.

Most Intel microprocessors support “HyperThreading” (Intel’s trademark for their implementation of “simultaneous multithreading”) — which allows the hardware to support (typically) two “Logical Processors” for each physical core. Processes running on the two Logical Processors share most of the processor resources (particularly caches and execution units).
