Feed: Redis Labs. Author: Simon Prickett. Redis University is pleased to announce the immediate availability of free, self-paced, on-demand online courses. A lot has changed in recent weeks, and many of us are now at home, perhaps a bit more than we’d like to be. To help make this shelter-in-place time as productive as possible, we figured this would be a great time to give the Redis community the chance to complete as many courses as you can, all at your own pace. Take as many courses as you like—just be sure to complete them before they close on May ... Read More

Feed: Redis Labs. Author: Itamar Haber. Earlier today, security firm TrendMicro published a blog post with findings from the company’s security researchers. The team had used Shodan, the popular search engine for internet-connected or Internet of Things (IoT) devices, to identify more than 8,000 unsecure Redis servers across various clouds. When left unsecured, such servers could be used by cybercriminals for nefarious purposes. A declining number of exposed Redis servers That number is substantial, but it demonstrates a constant, if not declining, number of exposed servers overall. About three years ago, I used the same method to count 9,916 such ... Read More

Feed: Redis Labs. Author: Kyle Davis. First, let me warn you that I am not a game developer. So this post, which has been rattling around in my head for a number of years now, is partly a look at how a theoretical game would work with Redis but also a metaphor to help readers understand how Redis works.  Phew!  With all that out of the way, let’s talk about implementing a game that is powered by Redis. We’re going to call this game Super Redis Brothers—it’s an action platformer connected to a central server. It stars Redisman, who needs ... Read More

Feed: Redis Labs. Author: Guy Royse. Like many software engineers, I enjoy a good game of Dungeons & Dragons. I love powering up my character and facing increasingly more powerful foes. Doing this right requires gold and experience. And the best way to get those things is a good old-fashioned dungeon crawl. If you need some context on D&D, this video might help. The short but overly simplified version: in D&D you explore underground complexes, fight monsters therein, and take their gold. Unfortunately, dungeons aren’t set up for the convenience of adventurers like us. Sometimes the monster is challenging but ... Read More

Feed: Redis Labs. Author: Loris Cro. It used to be that Redis Enterprise was just one of many offerings in the Google Cloud Marketplace, but now thanks to the partnership between Redis Labs and Google, Redis Enterprise is integrated into the Google Cloud Console. This integration means you not only can enjoy unified billing, but also that you can use your Google Cloud credits to pay for Redis Enterprise. Enabling the service Let’s take a look at how to enable the Redis Enterprise API in your Google Cloud project. The starting point is the sidebar of your Cloud Console. At ... Read More

Feed: Redis Labs. Author: Guy Royse. I’ve got a problem. I have tens of millions of players in my online game World of EverCraft (Not a real game. But if it was, it would be from Blizzards of the Coast!). This is a great problem to have. So many gamers! But when a new user signs up, it takes forever to determine if their desired username is taken or not. It’s a simple enough query but the vast amount of data makes it slow. Switching to Redis helped. Instead of a simplistic but slow SQL query: > SELECT COUNT(*) FROM ... Read More

Feed: Redis Labs. Author: Britiana Andrade. As we draw ever closer to RedisConf 2020 Takeaway starting May 12, we want to hear from you about the cool things you use Redis for. The Redis community is one of the most inspiring and creative groups of developers in the world—and we want to showcase the community’s achievements. That’s why we’re excited to announce the Rediscover Redis Competition! The Rediscover Redis Competition We’re challenging members of the Redis community to show off how they have rediscovered Redis. Almost every developer knows how to use Redis as a cache to build top-performing applications ... Read More

Feed: Redis Labs. Author: Kyle Davis. Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.—Dr. Ian Malcolm, in Jurassic Park “Best Practices” has become a trope in technology. Sure, you can do something with a given tool, but is doing so really a good idea? The fact that this topic comes up again and again speaks to the flexibility of our tools. Best practices are great for beginners to learn the right things from the get-go. The problem is that, sometimes, as software engineers, we have imperfect memories of these ... Read More

Feed: Redis Labs. Author: Loris Cro. Despite the complex-sounding name, probabilistic data structures are relatively simple data structures that can be very useful for solving streaming-analytics problems at scale. Probabilistic data structures make heavy use of concepts from information theory (such as hashing) to give you an approximate view of some characteristics of your data. The reason why you might be fine with an approximation versus a complete and precise description is because in exchange they save an enormous amount of storage space and deliver great performance compared to traditional data structures. Streaming analytics One situation where performance and space ... Read More

Feed: Redis Labs. Author: Dave Nielsen. The Redis community is one of the most engaging, curious, and inspiring groups of developers and IT folks in the world. We love hearing how you’ve used Redis to solve problems and how it’s changed the way you build and scale your applications. We also recognize there are many ways you like to share your thoughts and experiences, such as through Twitter, YouTube, Stack Overflow, blogs, Github, and in-person meetups (once the Coronavirus is under control).  To help you share in the ways that work best for you, we’ve created a community page to ...
