Author: Andy Glover Since releasing Spinnaker to the open source community in 2015 , the platform has flourished with the addition of new cloud providers, triggers, pipeline stages, and much more. Myriad new features, improvements, and innovations have been added by an ever growing, actively engaged community. Each new innovation has been a step towards an even better Continuous Delivery platform that facilitates rapid, reliable, safe delivery of flexible assets to pluggable deployment targets.
Wake up! It's HighScalability time: The web is 30 ! Some say it's not the web we wanted. But if we got that web, would it have ever grown so big? Worse usually is better. Do you like this sort of Stuff? I'd greatly appreciate your support on Patreon. Know anyone who needs cloud? I wrote Explain the Cloud Like I'm 10 just for them. It has 40 mostly 5 star reviews.
Are you deploying PostgreSQL in the cloud and want to understand your options for achieving high availability? In our previous blog post, Managing High Availability in PostgreSQL – Part I , we discussed the capabilities and functioning of PostgreSQL Automatic Failover (PAF) by ClusterLabs. In Part II, we’re introducing you to an alternative open source tool, Replication Manager from 2ndQuadrant, to be closely followed by Part III where we dive into our third alternative, Patroni by Zalan
Relational databases have been around for a long time. The relational model of data was pioneered back in the 1970s by E.F. Codd. The core technologies underpinning the major relational database management systems of today were developed in the 1980–1990s. Relational database fundamentals, including data relationships, ACID (Atomicity, Consistency, Isolation, Durability) transactions, and the SQL query language, have stood the test of time.
Smart developers are always looking ahead for ways to adapt in the ever changing world of web development. As trends emerge, new opportunities will arise. No one could have imagined what the web would look like today 20 years ago, so who knows what the coming decades will hold. Staying on top of the latest web development trends could eventually help you land a job that doesn’t exist yet.
The 737Max and Why Software Engineers Might Want to Pay Attention As someone with a bit of a reputation for talking about aviation and software development and operations , I’ve been asked about the 737Max repeatedly over the past week. I’ve been watching this story develop since November of last year, when the Lion Air 737Max crashed. Given recent developments, if you want a pure-aviation take on what’s going, there are better people to ask.
In our family it's a tradition that you get to decide what we'll have for dinner when it's your birthday. On my daughter's last birthday, she picked pizza. I took her to the nearby pizza shop to decide what pizza to get. A large screen dominates one wall of the pizza place, showing each order as it progresses through each stage of preparation. As I was looking at the screen, I noticed some names suddenly switched.

Google formally announced Lite Pages the other day and the response has been… let’s say mixed. Understandably so. The announcement post was a fairly typical product announcement post which is to say it was light (no pun intended) on the technical details and leaves a lot of open questions. Sometimes that’s fine. But in this case, the announcement has to deal with Google making changes to HTTPS content which, as you would expect, makes folks a little more nervous.
Small moves, smartly made, can set big things in motion. That’s a key to succeeding in a world of mounting performance pressure. In a previous post , I briefly alluded to the need to “zoom out” to smartly make small moves. In today’s post, I want to focus in more detail on the need to zoom in. Zoom out/zoom in strategies �
As you might know, sponsored advertisements are one of the things that are funding The Polyglot Developer and everything it accomplishes, so keeping sponsors happy and supplying them the metrics they need is very important. However, in most circumstances, more specifically when it comes to banner creatives, page views is not enough. For example if your sponsors or potential sponsors asked how many impressions each of your advertisement zones gets, you can’t just list off the page views tha
Do you know how to be a great conversation partner? I know I’m making progress, but it still feels like I have a long way to go. I’ve had a lot of teachers—my uncle, great books, friends, my spouse. But Celeste Headlee has earned a place high on my list of influential teachers of conversation. I have been reading and listening to more and more of Celeste’s work these days, and I always feel it helps me.
In this article, we are going to see how to create a multi subnet cluster spanning across multiple subnets for lab purposes. Creating such an environment should help creating Availability groups simulating a far replica residing in a different Data Center (Subnet) acting as a disaster recovery site in your lab for learning/experimenting real world […].
I strongly believe in the community. Communities are the real strength of open source. Not just the theoretical ability to study, modify and share code – but the fact that other people out there are doing these things. Creating a base of knowledge and a network of relations.These can become work relationships, valuable discussions, open source tools, or even friendships.
An important concern in optimizing the hardware platform is hardware components that restrict performance, known as bottlenecks. Quite often, the problem isn’t correcting performance bottlenecks as much as it is identifying them in the first place. Start with obtaining a performance baseline. You monitor the server over time so that you can determine Server average […].
This is the last in a series of scheduling- and calendaring-related topics. This one’s about my overall strategy of using scheduling as a tool to manage my time. Clearly, managing my time isn’t the same as managing my calendar, but managing the latter does help with the former. The essence of my strategy is this: I care about my time, but others care about my calendar, so I can forestall a lot of intrusions on my time by using my calendar intelligently.
A lot of factors are considered in a build vs buy decision. What are the technical capabilities of existing systems? Is the functionality a core offering of my own product? How complex would it really be to build? How much would buying cost? What about switching costs? One thing I find myself considering more and more is the philosophy of the people who are building the technology I am evaluating.
The first time I made an image responsive, it was as simple as coding these four lines: img { max-width: 100%; height auto; /* default */ }. Though that worked for me as a developer, it wasn’t the best for the audience. What happens if the the image in the src attribute is heavy? On high-end developer devices (like mine with 16GB RAM), few or no performance problems occur.
I’ve written a new 65-page ebook, titled DevOps for the Database. Drawn from what I’ve observed over the last 15 or so years in my own experience as well as that of many others, it tries to answer why and how some organizations deliver value to customers fast, run data-intensive applications with high quality, and have great engineering cultures—and why some don’t.
