Using Google Gemini’s File API with ColdFusion

/ / No Comments
I promise, I’m not turning this back into a ColdFusion blog, but as I prepare my presentation next week at Summit and update my Google Gemini code for some ColdFusion demos, I ran into a particularly gnarly bit that I wanted to share in a post. For the most part, I’ve had no issues using Gemini’s REST APIs in ColdFusion, but the File API ended up being more difficult. If you go the documentation for uploading, and use the ‘Shell’ language tab, you can see an example like so: MIME_TYPE=$ (file -b --mime-type "$ {IMG_PATH_2}")NUM_BYTES=$ (wc -c < "$ {IMG_PATH_2}")DISPLAY_NAME=TEXTtmp_header_file=upload-header.tmp# Initial resumable request... more →

Using the Gemini File API for Prompts with Media

/ / No Comments
Using media in your prompts (what’s called ‘multimodal’) with the Gemini API is fairly simple in small cases. You can encode your input with base64 and pass it along with your prompt. While this works well, it’s got limitations that may be quickly hit – most specifically a file size limit of 20 megs. A few months ago, I shared a demo of using your device’s camera to detect cat breeds. With today’s cameras taking incredibly detailed pictures, I hit that limit right away and had to write some code to resize the image to a smaller size. Luckily, the Gemini API has a better way of handling that, the File API. The File API # This API provides a separate method... more →

How to Get a Base64 Version of a File From Command Line

/ / No Comments
A while back I wrote an article on how to Convert Image to Data URI with JavaScript. It’s a neat trick developers can use for any number of reasons. Instead of abusing canvas, however, why not simply get the base64 data from command line? You can use base64 and pbcopy to convert a file to base64 and copy it to the clipboard: # base64 gets data, pbcopy copies to clipboard base64 -i logo.jpeg | pbcopy Once you have the file data copied in base64 format, the URL format to use the data is: # data:{mime-type};base64,{data} data:image/jpeg;base64,/9j/4AAQSkZJRgAB...... While base64 data and data URIs do look cryptic, they’re useful to avoid making requests to other files. I use them... more →

Download Data as a File with Alpine.js

/ / No Comments
As my readers know, I’ve been updating some of my earlier Vue.js examples to demonstrate how they would work with Alpine.js. Normally I post these "conversions" when I see one of the Vue posts pop up in my stats. Today I noticed this entry was "trending" – Vue Quick Shot – Downloading Data as a File. I thought it would be a great candidate for showing an Alpine version. Let’s take a look. While I won’t repeat everything from the previous post, I’ll quickly cover how it worked. First, it makes use of the download attribute of the anchor tag. This will take a normal link operation and instead ask the browser to download the resource at the... more →

Determine Default App for File Type from Command Line

/ / No Comments
One quality of life improvement any developer can make for themselves is ensuring different file types open in the app they’re most proficient in. If you know me, you know I prefer accomplishing as much as possible from the command line. The duti utility allows users to determine default file type from command line. The duti utility allows developers to query which app is the default for different file types. You can install duti with brew: brew install duti Once you have duti available, you can check on the default app for file type with the following command: ~ duti -x md Xcode.app /Applications/Xcode.app com.apple.dt.Xcode You can set the default app by using its package: duti... more →
