Hi, I am starting a project on active ventilation control and came across your page on ThingsSpeak when googleing dew point. I am looking into using a series of ESP 8266 to give feedback about the state of the room climate. It looks like your monitoring system is set up and working great. Please tell me, how you are monitoring the dew point and di you write the code? Many thanks Jason

hi, sry for late answer. posted links explaining it in my blog ... https://de.mathworks.com/help/thingspeak/analyze-your-data.html

FontCode

Research from Columbia Computer Graphics Group can create textual encryption by minute altering of font characteristics using neural networks:

We introduce FontCode, an information embedding technique for text documents. Provided a text document with specific fonts, our method embeds user-specified information in the text by perturbing the glyphs of text characters while preserving the text content. We devise an algorithm to choose unobtrusive yet machine-recognizable glyph perturbations, leveraging a recently developed generative model that alters the glyphs of each character continuously on a font manifold. We then introduce an algorithm that embeds a user-provided message in the text document and produces an encoded document whose appearance is minimally perturbed from the original document. We also present a glyph recognition method that recovers the embedded information from an encoded document stored as a vector graphic or pixel image, or even on a printed paper. In addition, we introduce a new error-correction coding scheme that rectifies a certain number of recognition errors. Lastly, we demonstrate that our technique enables a wide array of applications, using it as a text document metadata holder, an unobtrusive optical barcode, a cryptographic message embedding scheme, and a text document signature.

Just A Line

Google Creative Lab have released an Augmented Reality doodle app that will work with all modern Android phones, and allows you to create a video of your work:

Make simple drawings in AR, then share your creation with a short video.

Based on our previous open-source experiments with ARCore, Just a Line is an app that lets you make simple drawings in augmented reality, then share your creation with a short video. Touch the screen to draw, then hit record and share what you make. If you’re a developer, you can use the open-sourced code as a starter project for ARCore.
