RedLine13 integrates with AWS to handle the spin up, management, and termination of your load generator servers without you ever having to worry about any of those details. We also support starting load generators from any AWS region. This is useful for when you want to simulate traffic which originates from geographically diverse sources. In this brief post, we will show you how to run a multi-region test to achieve this. This is available in our paid and free plans.

When our test runs, in this particular example you can see that we have started load generators in several regions around the globe. This test generates traffic originating from the United States, Ireland, Germany, and Japan:
The TIDA-01379 reference design permits to generate fast load transient signals required for the evaluation of converter stability. The board includes three separable load transient generators that are either regulated or non-regulated and are able to support different load configurations. The loads can be referenced to ground or floating.
But it's not the main functionality of the project. It's the generator form that allows users to modify the animated images as desired from within the web-site and create own unique "pre-loaders". Just click on a desired animation and you can set your own custom image colors, size, animation speed, frames amount and other advanced options. All loading icons on Preloaders.net project are free of charge both for personal and commercial use (except for re-distribution, which requires a reference to the project).
StresStimulus is a load testing tool for websites, mobile and Enterprise apps. It determines the web performance and scalability of your application under the rigors of heavy traffic load. Hundreds or thousands of physical users are realistically emulated through on-premise load generators or in a cloud testing environment. At the same time, server monitoring information is collected in real-time to pinpoint application performance bottlenecks and isolate web speed issues. StresStimulus makes website stress testing and mobile performance testing super easy thanks to its end-to-end test wizard that walks you through recording, configuring and executing tests. It also saves time on mobile app load testing due to its out-of-the-box support for native app frameworks. What sets StresStimulus apart from other performance testing tools is its support for complex websites and apps combined with its competitive pricing.
Run tests from a single test machine or spread virtual users between any number of load generators instantiated on-premise, on your private cloud or in public clouds such as Amazon Web Services or Azure.
High ScalabilityCloudTest can test thousands to millions of users concurrently generating traffic on your site or app. Due to the flexible nature of the architecture, setting up to test for a 100 user test versus a 100K user test does not require much more effort. Basically, as soon as testing needs and test windows are defined, spin up the environment and load generators required and start testing.
Lithophane GiftsThe best Christmas presents have a personal touch, and 3D printing makes personalization easier than ever. Nothing is more personal than memories shared by loved ones. Memories captured in a photo can be preserved for generations, and there is perhaps no better way to preserve these memories than with a 3D printed lithophane lamp.Lithophane lamps are a novel way to display cherished pictures and they make for excellent, 3D printed Christmas gifts. The recently released lithophane lamp maker at Lithophane Maker generates a lithophane lampshade that can fit on lamps you already have in your home. This new process is much simpler than what was previously required to design and assemble a lithophane lamp ( -this-3d-printed-lithophane-lamp-makes-your-photographs-3d.html). Before the tools at Lithophane Maker were available, makers had to 1) buy several items (LED strip, DC Jack, Wire, etc), 2) crop pictures to the required aspect ratio, 3) create lithophanes from the pictures, 4) print the lithophanes and lamp structure separately, and 5) assemble everything together which includes soldering. In summary, this pioneering (but complicated) process requires that the lamp structure, lithophanes, lighting, and power had to be designed and assembled which can be time consuming, error prone, and often very frustrating if the many parts do not fit together securely (or at all).The lithophane maker tool makes this process much easier. The user simply uploads 1-4 pictures, and the lamp lithophane maker automatically combines the images together and creates a custom border and frame. No image cropping or CAD design is required, and the tool turns your pictures into a 3d printable stl model of a 1-piece lampshade that can be mounted to a lamp. You don't have to solder wires together to make custom circuitry that could be a fire hazard. The lampshade's interface can also be customized, though the default settings make the lampshade fit a typical lamp. The size of the lampshade is easily adjusted by changing the lampshade's radius and the dimensions of the lampshade's frame. The height of the lampshade lithophane is shown to the user before the lithophane is created, though it is set by the selected radius and the aspect ratio of the uploaded photos. The lamp lithophane maker greatly simplifies the design process, and saves its users quite a bit of unnecessary headache.Lithophane Maker was created by a 3D printing hobbyist for 3D printing hobbyists. The website includes several free tools that turn photos into lithophane models with frames, holes, and adapters that make it possible to mount a lithophane under a hook, on a lamp, or on a night light. The lithophane tools at Lithophane Maker are estimated to have saved users thousands of hours in the two months that they've been available. If you find any bugs or have any suggestions, you can share them with me by joining the Lithophane Maker User's group on Facebook or by emailing me at support@lithophanemaker.comRecent updatesSeveral improvements have been made since my last blog post, and many were suggested by users like you! To list a few: 1) A frame was added to the night light lithophanes. Turn you pictures into a night light lithophane (here) that is backlit by a night light you already own. 2) The Lithophane Lamp Maker now has a "clamp" interface that gives you a greater tolerance on your interface with the lamp, so that it is easier fit your lamp and takes less time to print. 3) I made the Circular Lithophane Maker more error proof by making it nearly impossible for the user to put the cropping circle outside of the picture. 4) All of the lithophane makers now give you a zipped file that includes your stl file and the settings you used to make the stl file. 5) I updated aspects of the server's back end to make it so that I can debug errors that aren't reported to me. That said, please continue to report any bugs you find, because this works best, and I will fix the error fastest if you ask!
Nuclear power plants are essentially base-load generators, running continuously. Where it is necessary to vary the output according to daily and weekly load cycles, for instance in France, where there is a very high reliance on nuclear power, they can be adapted to load-follow. For BWRs this is reasonably easy without burning the core unevenly, but for a PWR (as in France) to run at less than full power for much of the time depends on where it is in the 18 to 24-month refueling cycle, and whether it is designed with special control rods which diminish power levels throughout the core without shutting it down. So while the ability on any individual PWR reactor to run on a sustained basis at low power decreases markedly as it progresses through the refueling cycle, there is considerable scope for running a fleet of reactors in load-following mode. Generation III plants and small modular reactors have more scope for load-following, and as fast neutron reactors become more established, their ability in this regard will be an asset.
The impact of high levels of intermittent, low cost power will be to reduce the load factors of base-load power generators, and thereby increase their unit costs per kilowatt-hour. Given the high capital costs of nuclear, such an impact will significantly increase the levelised generation costs of nuclear. For example, a 15% decrease in the capacity factor of a nuclear power plant could increase its levelised cost by about 24%.
A quite different rationale applies to using nuclear energy (or any other emission-free base-load plant) for hydrogen. Here the plant would be run continuously at full capacity, with perhaps all the output being supplied to the grid in peak periods and any not needed to meet civil demand being used to make hydrogen at other times. This would mean maximum efficiency for the nuclear power plants, and that hydrogen was made opportunistically when it suited the grid manager, with electrolyser capacity factors above 65% readily achieved.
