Why would F5, best known as a high-end, enterprise Internet Service Provider (ISP), acquire NGINX, which most people know because of its high-speed, open-source web server, NGINX?
When you describe it that way, this $670 million acquisition sounds like a great deal… for the 1990s. But both companies are far more than that, and together they hope to become the backbone for Software-as-a-Service (SaaS) cloud services and other net-based application delivery services. Now, that’s a 21st century deal.
Let’s make one thing clear immediately: While a speedy web server is all well and good, this deal is not about web servers per se — nor is it about what had long been seen as a rivalry between Nginx and the Apache HTTP Server.
No, François Locoh-Donou F5’s CEO explained ahead of the deal’s completion that the two companies will be about providing DevOps for cloud networking. Specifically, the pair will bring together “the modern, open-source applications developed in and for the cloud and the traditional, mission-critical applications that are often the last to migrate out of the enterprise data center.”
NGINX CEO Gus Robertson assures NGINX customers that “F5 is committed to the NGINX open-source technology, developers, and community.” NGINX’s open-source heart will keep beating on in F5’s body.
As for NGINX’s commercial products, moving forward Robertson says they will be:
- Infusing F5 security capabilities into NGINX products.
- Extending NGINX Controller with additional control plane functionality to manage lightweight application delivery controller (ADCs) and load-balancers.
- Enhancing the NGINX Controller API Management Module.
- Accelerating the development of a new NGINX Controller Service Mesh Module for microservices and Kubernetes capabilities.
When you put it all together, you see the two joining forces to create an open-source-based, high-end network application services for today’s cloud-based IT world.
NGINX’s customers and partners like this idea. At Red Hat Summit in Boston, NGINX VP of Global Strategic Alliances and Partnerships Christine Puccio said: “We already have really good movement on on controllers. A lot of our security and management partners want to plug into out open APIs. With our partners, we’ve developed kind of a target list of features they need, and we already have designs in the pipeline.”
To make all this work and help integrate F5 and NGINX’s products together, Robertson, along with the company’s founders and its 250-employee team, will continue to run the NGINX business from its San Francisco home.
The Feature That You Likely Didn’t Know Your iPhone Camera Had
If you’ve ever wanted to take photos while recording video without having to resort to screen captures of video stills, Apple has something for that in almost all of the new phones it’s released since September 2019. QuickTake is a built-in and easy-to-use feature that lets you record video and snap pictures using the same device, with no need to switch between camera modes or download any additional camera apps.
There’s a small catch, however. While the process is very simple when you know how to turn it on, it may affect the overall quality of your photos. In essence, if your photo settings are adjusted for higher-quality images, those settings won’t carry over to video. And since QuickTake uses video camera sensors rather than the regular ones, there’s not much you can do to change that. Newer iPhone models do support up to 4K video, which could yield better results.
Regardless, whatever your reasons for wanting to take photos while simultaneously recording video with your iPhone may be, it’s a very simple process.
How to use QuickTake
Making use of your iPhone’s QuickTake feature doesn’t require any special setup or settings changes — it’s already part of the default Camera app so long as you’re using iOS 13 or newer.
- Open the Camera app and leave it on the default Photo mode. You should see “Photo” highlighted in yellow, just above the Shutter Button.
- When you’re ready to record, press and hold the Shutter Button to begin recording video. Recording will stop if you release the Shutter Button.
- Slide your finger from the Shutter Button over to the Lock icon in the bottom-right corner of the screen (where the button for swapping between front- and rear-facing cameras normally is).
- The Lock icon will change to a small Shutter Button, and the video recording button will change to the regular recording icon. At this point, your iPhone will continue to record video if you remove your finger from the screen.
- While your video is recording, tap the small Shutter Button in the bottom-right corner of the screen to take photos.
- Tap the recording button (it will look like a Stop button while recording) to stop taking video.
The QuickTake video you’ve recorded and all of the photos you snapped will appear in your Photos app. Due to videos being added to the Photos app once recording stops (rather than when it starts), the new video will appear after your QuickTake photos.
The Science Behind The Deadly Lake
A buildup of carbon dioxide gas is not uncommon for crater lakes, with many of them occasionally releasing bubbles of it over time. Volcanic activity taking place below the Earth’s surface (and below the lake itself) will cause gasses to seep up through the lakebed and into the water. Something that generally isn’t a concern as deeper, colder water is able to absorb substantial amounts of carbon dioxide, but if the concentration gets too dense it can create bubbles that float up to and burst on the surface of the water.
This in itself is common, and the volume of carbon dioxide usually released in this manner will dissipate into the air quickly. However, it’s theorized that Lake Nyos had been amassing an uncharacteristically large amount of gas due to a combination of factors like location, local climate, overall depth, and water pressure. Once that buildup had been disturbed, it all came rocketing out.
Whether it was due to a rock slide, strong winds, or an unexpected temperature change throwing off the delicate balance is still unknown. But whatever the catalyst was, it caused the lower layer of deep, carbon-infused water to start to rise. Which then began to warm up, reducing its ability to contain the gas. The resulting perpetual cycle of rising waters and gasses creates the type of explosion you might see after opening a carbonated beverage after it’s been shaken vigorously.
The Super Nintendo’s Secret Weapon
The Super Nintendo featured seven different video rendering modes, each offering a different level of display detail, shown in one to four background layers. Most of the Super Nintendo’s games utilized Mode 1, which could display 16-color sprites and backgrounds on two layers plus a 4-color sprite on a third layer. This little trick was the key to the parallax scrolling effect you’d see in games like “Super Mario World,” where background elements would scroll at different rates from foreground elements.
Mode 7, however, was the only one of these display modes that permitted advanced visual effects. In a nutshell, Mode 7 allows the Super Nintendo to take a 2D image and apply 3D rendering effects to it, such as scrolling, curving, stretching, and more. By switching to Mode 7, games could transform one of their background layers into an independently moving image, which could be used for gameplay modifications and simple spectacle. Plus, with a bit of creative warping, a 2D image could be changed into a pseudo-3D view, having 2D sprites move around in a flat 3D space. It’s kind of like rolling a ball on a treadmill.
