Security with AWS Cognito: Building Your First User Pool

Building a secure authentication service is a complex and time-consuming task and you expose your app and your users to unnecessary risks. This is where third-party authentication services come in.
If you're already heavily invested in the AWS ecosystem, Cognito offers a seamless and secure way to manage user authentication for your web and mobile applications since it integrates smoothly with other AWS services like API Gateway and IAM.
Amazon Cognito is an identity platform for web and mobile apps. It’s a user directory, an authentication server, and an authorization service for OAuth 2.0 access tokens and AWS credentials.
An Amazon Cognito User Pool is a fully managed user directory that simplifies user authentication and authorization for web and mobile applications. It securely stores user information, handles user sign-up, sign-in, and password recovery.
An Amazon Cognito Identity Pool is a service that simplifies user authentication and authorization for web and mobile applications. It manages user identities, provides temporary AWS credentials, and enables flexible access control to AWS resources.
This tutorial is intended for beginners, as such we’ll be utilizing the AWS Console instead of the CLI. Additionally, I am expecting that you already have your AWS Account ready for use.
Go to your AWS Console, and look for Cognito. Click on Create User Pool.
Once your User pool has been created, you can click on it and navigate to App integration. Once you're there, scroll down to your App clients and click on your App client. Navigate to the Hosted UI segment and click on View Hosted UI.
Signing in will not give any response, as we didn't handle our callbacks properly.
This walkthrough introduced you to Amazon Cognito's user pools and hosted UI service, which is just the beginning of your journey through the Amazon cloud.

What Is Edge Computing? 7 Key Benefits for Businesses

Edge computing extends computing power and information storage to the network periphery, cutting down round-trip time, increasing privacy, and has numerous other advantages for today’s enterprises.
Edge computing reduces latency which means the distance between a data source and a data processing unit. This benefit comes in handy for real-time processing applications such as self-driving cars and augmented reality and industrial automations that require split-second decisions.
Fog computing helps improve data security and minimizes the movement of data to the cloud by keeping data near where it is generated. This method enables companies to observe data protection policies within their geographic regions.
By shifting data processing to closer points to the source of the information, companies are able to filter the data and only send relevant information to a central cloud for more detailed study. In this way, bandwidth is preserved, and the cloud menace is mitigated especially in the storage of data thus reducing storage expenses.
Edge devices would still be functional, able to gather and analyze data to mitigate such challenges of network failure and improve overall returns on hours worked.
With edge computing, a business can easily scale up its infrastructure when the need arises. This quality is crucial for sectors at the peak of their growth cycle or for those that experience seasonal changes in demand.
Edge computing allows processing data created by IoT devices closer to the source of the data and hence speeds up data processing near the source. This quality is boon for smart factories, connected healthcare equipment, smart agriculture certainly enabling speedy outreach and local data processing.
Fog computing reduces overhead by minimizing data transfers and hence saves energy. Edge computing can assist in reducing the environmental impact by helping companies comply with environmental regulations faster and help in making the world a healthier place.
With these seven main advantages, edge computing is revolutionizing company operations by enabling more rapid and effective data processing near the source, boosting sustainability and help in keeping ahead of the trends by adopting cutting-edge technology.

HP OmniBook Ultra 14 review: a solid entry for AMD

The HP OmniBook Ultra 14 features an AMD Ryzen AI 9 chipset for great performance and has a surprisingly good battery life, but it’s not quite good enough to make it onto our list of the best best laptops.
The OmniBook Ultra 14 has a few shortcomings including a slightly underwhelming IPS display, the touchpad could be haptic, and list prices can be expensive.
The OmniBook Ultra 14 has several configurations starting at $1,350 for the base model featuring an AMD Ryzen AI 9 chipset, 16GB of RAM, a 512GB SSD, and a 14.0-inch 2.2K IPS display (the only option).
The OmniBook Ultra 14 is a well-made laptop with a chassis, keyboard deck, and lid that all resist bending, flexing, and twisting.
The keyboard of the OmniBook Ultra 14 is great, but unfortunately, the touchpad is less impressive. There’s plenty of space for a larger version but, for whatever reason, HP didn’t include the excellent haptic touchpad it used on the OmniBook Ultra Flip 14.
The 14.0-inch 16:10 2.2K (2240 x 1400) IPS display is good enough but falls a bit short of expectations.
For connectivity, the OmniBook has just two USB-C ports with Thunderbolt 4 and a USB-A port. The webcam is HP’s latest 9MP version, and it will support Microsoft’s Copilot+ PC initiative including enhanced Studio Effects software, along with HP’s own AI Companion features that will be rolling out.
When comparing the most recent chipsets, the AMD Ryzen AI 9 that the OmniBook Ultra 14 utilizes takes a strong lead in performance. It will rip through the most demanding productivity workflows but won’t be the best for video editing or running more than older games at limited graphics.
The OmniBook Ultra 14 has 68-watt-hour battery life that is just OK for a 14-inch laptop.
Overall, the HP OmniBook Ultra 14 is a good device, and it's a decent value for a very nicely configured laptop. But it’s not as impressive as HP’s OmniBook Ultra Flip 14, despite being priced similarly.

Nvidia’s DLSS is an obvious choice over AMD’s FSR, but this shouldn’t dictate your GPU buying decisions

Nvidia's DLSS has taken the market by storm, with its flagship RTX 4090 providing the best performance on gaming PCs to date.
AMD FSR is good for handheld gaming, but it is not superior to Nvidia's offering.
DLSS 3 has shown to push in-game frame rates above and beyond usual standards at higher resolutions with ray-tracing enabled.
However, upscaling methods should not be the only factor when deciding which GPU to buy, especially since plenty of games run great on AMD's Radeon GPUs.
AI-powered upscaling methods such as DLSS 4, FSR 4 and XeSS are becoming prominent factors in the future of PC gaming.
The worry is that game developers will release poorly optimized games and use upscaling methods as a quick solution.
Therefore, upscaling tools should not be the deciding factor for your GPU choice, since your GPU's power and hardware specifications matter the most.
AMD's decision to allow FSR 3 to be used on a wide range of graphics cards goes a long way in showing where its loyalties lie.
Although AMD GPUs cannot use DLSS, dismissing a purchase of an AMD GPU solely based on that is a poor choice.
If Nvidia allows DLSS 3's successor to be used with older GPUs, then users should not let this factor dictate their GPU upgrade decision.
