This article is written by Preetam Jinka , Senior Infrastructure Engineer at ShiftLeft. Originially published as Time Series at ShiftLeft. Time series are a major component of the ShiftLeft runtime experience. This is true for many other products and organizations too, but each case involves different characteristics and requirements. This post describes the requirements that we have to work with, how we use TimescaleDB to store and retrieve time series data, and the tooling we’ve develope
A new report explores how far companies have come with microservices. Fads come and go in the technology world—anyone remember AJAX ? When new, shiny things appear, architects often struggle to determine whether this is merely the latest fad or a genuine future direction. Microservices are evolving from fad to trend. Several years ago, many companies experimented with microservices but had doubts about the operational complexity and engineering maturity required to achieve success.
Subtitle: Making Windows Slower Part 3: Process Destruction. In the summer of 2017 I wrestled with a Windows performance problem. Process destruction was slow, serialized, and was blocking the system input queue, leading to repeated short mouse-movement hangs when building Chrome. The root cause was that Windows was wasting a lot of time looking up GDI objects during process destruction, and it did this while holding the system-global user32 critical section.
Last week I had the opportunity to present at a technical SEO conference about performance. At the speakers dinner, I was enjoying a really good conversation with a few folks I met. At one point, I brought up quokkas because they’re amazing and I desperately want to hang out with one. Or a few. Anyway. It turns out, the other folks at the table were not familar.

Git is the go-to version control tool for most software developers because it allows them to efficiently manage their source code and track file changes while working with a large team. In fact, Git has so many uses that memorizing its various commands can be a daunting task, which is why we’ve created this git cheat sheet. This guide includes an introduction to Git, a glossary of terms and lists of commonly used Git commands.
The number of performance metrics is large and increases every year. It's important to understand what the different metrics represent and pick metrics that are important for your site. Our Evaluating rendering metrics post was a popular (and fun) way to compare and choose rendering metrics. Recently I created this timeline of performance metric medians from the HTTP Archive for the world's top ~1.3 million sites: Here's the same chart for mobile: People who have worked on web performance won't

The tremendous growth in visual computing is fueled by the rapid increase in deployment of visual sensing (e.g. cameras) in many usages ranging from digital security/surveillance and automated retail (e.g. smart cameras & analytics) to interactive/immersive environments and autonomous driving (e.g. interactive AR/VR, gaming and critical decision making).
I recently came across the need for a date/time parser that used natural language processing. Maleega’s date picker is extremely barebones and needed replacing. I left it barebones because I wanted time to figure out how to build a good date/time picker. Every one that I’ve used has felt clunky. This is probably because of the inherent challenges with date and time.
With Google's new expanded text ads (90 characters vs. 45) there is more room to make your case to potential buyers. One of the best ways to optimize a PPC account is to improve the ad text. This article shows how you can use local landmarks to boost click-through rates and conversions.

This is the latest edition of our newsletter. To receive the email version please subscribe here. So another AWS re:Invent has come and gone and . well, we’ve almost recovered. It was, as expected, another fascinating and stimulating week. We spent most of our time chatting to various folk about what they are doing with AWS now, and where they hope to proceed in 2019.
By now, I have to be on record at least a few thousand times in saying that WebPageTest.org is an absurdly valuable tool. Pat gave the performance community an incredible gift by building it and making it available to the broader community for free. I spend a lot of time in WebPageTest. A lot of time. A while back, I made myself a little Alfred (like Spotlight but significantly more powerful and useful) workflow to make it easy for me to fire off a test quickly.

Historical Archive?—?Cloud Camp?—?September 2008 [I found this in an archive and thought it was worth sharing 10 years on.

There are a lot of password managers on the market, some in the cloud, some local, all with features that may or may not be useful in all circumstances. I’m personally an advocate of being in control of your secure information and shedding reliance on closed source or cloud alternatives. This is why I use pass , the standard unix password manager.
In the perfect world, each team in our organisation would spend 100% of their time on improving products and delivering value to customers. Every second of every day would be spent producing value which increases customer satisfaction and the business’s bottom line. This perfect world does not exist due to the limited capacity of human cognition. No single person can have all the skills and knowledge needed of the business and of the technical solution.
