Amazon EC2 Inf1 instances and AWS Neuron now support YOLOv5 and ResNext deep learning models as well as the latest open-source Hugging Face Transformers. We have also optimized the Neuron compiler to enhance performance and you can now achieve an out-of-the box 12X higher throughput than comparable GPU-based instances for pre-trained BERT base models. These enhancements enable you to effectively meet your high-performance inference requirements and deploy state of the art deep learning models at low cost. 

You can use Amazon Neptune resources tags to add metadata and apply access policies to your Amazon Neptune resources. Now, you can allow resource tags set on your Neptune clusters to be automatically copied to any automated or manual database snapshots that are created from your clusters. Tags can be used with AWS Identity and Access Management (IAM) policies to manage access to Neptune resources and control what actions can be applied to those resources.

Amazon Rekognition Custom Labels supports the ability to use an AWS Key Management Service (KMS) key, to encrypt the image data delivered to the Rekognition Custom Labels service to train your custom machine learning model. By default, Amazon Rekognition Custom Labels encrypts the image data at rest using server-side encryption. With this release, if you provide Amazon Rekognition Custom Labels with your KMS key or alias ARN, Amazon Rekognition Custom Labels will use that KMS key instead to encrypt your training and test images.

Does anyone know how to generate a pair of synchronised non-overlapping square waves on the two channels of a FeelElec/FeelTech FY6900? The aim is to drive a synchronous dc-dc converter output stage. Attempts through the front panel, and accompanying PC control software, have failed so far. I contacted the company, which replied, but I could …

A plea for help has arrived in the EW inbox Does anyone have any information on an RS 257-571 panel meter? The data sheet would be perfect, but if you have a heap of ancient catalogues around, a scan of the catalogue page would probably be enough. Reports are that it is a 4 1/2 …

A sensor that I somehow missed, despite it being a popular building block in module form is the WCS1800 current sensor from Winson of Taiwan. It is part of a large family of current sensors from the same company with widely varying characteristics – in this case measuring ±35A dc or 25Arms ac. Bandwidth is a respectable 23kHz. …

I had a need to put some nominally 12V modules into a vehicle. They are specced at 12±0.5V, or similar. So putting them in a vehicle that will be charging at 14.4V and might even experience load-dump (the voltage surge that happens if the battery becomes disconnected when the engine is running) seemed too much …

A long time ago the term ‘white paper’ got hijacked. It was a phrase to describe a useful document about a subject. Then the worst kind of marketing folk realised that techies respected white papers, and started to label pages of meaningless fluff with ‘white paper’. From then on it was a down hill slide …

I was all ready to describe something that I knocked up over a couple of evenings during the lovely Bank Holiday. Then a friend asked: ‘why don’t you get people to work out what it is?’ So, short of ‘a mess’ or something impolite, what did I make? Some time later….. The wise correspondents of this …

I need an adjustable power resistor that can be switched with a resolution of 1Ω. After some thought and web surfing, I bought some 10W wirewounds, which are available in E24 values so that 1, 3, 12 and 24Ω are available. This meant that a binary progression incrementing in 3Ω steps is easily possible, with …
