It is primarily used to generate detailed images conditioned on text descriptions, though it can also be applied to other tasks such as inpainting, outpainting, and generating image-to-image translations guided by a text prompt.”. This […]
0 0 When using AI models like Stable Diffusion, sometimes input images need to be of a specific size. In case of Stable Diffusion, multiples of 64 are required. Stable Diffusion (at least 1.5) works best with images of 512 pixels in width or height. If you have an image that is […]
0 0 In the IoT world, some devices generate large volumes of events that can be difficult for back-end systems to process in real time. Of course you can use NiFi to throttle messages, however this will not be sufficient if the flow of events is consistently higher than what can be […]

For example CPUs getting stuck when assigning multiple CPUs to a VM and issues with auto adjusting the guest resolution when resizing the VM window. These annoyances drove me […]
0 0 Previously I wrote about generating random data which conforms to an AVRO schema (here). In a recent use-case, I encountered the situation where there were several separate schema files containing different AVRO types. The message used types from those different files. For the generation of random data, I first needed […]
