QUESTION
I am trying to make sense of the following presentation, see page 27:
Could someone please describe the command line tools available in libjxl that can help me work with existing palettes ?
I tried a naive:
...ANSWER
Answered 2022-Mar-29 at 15:39The libjxl encoder either takes a JPEG bitstream as input (for the special case of lossless JPEG recompression), or pixels. It does not make any difference if those pixels are given via a PPM file, a PNG8 file, a PNG24 file, an RGB memory buffer, or any other way, if the pixels are the same, the result will be the same.
In your example, you have an image that is just solid white, so it will be encoded the same way regardless of how you pass it to cjxl.
Now if those pixels happen to use only few colors, as will be the case for PNG8 since there can be at most 256 colors in that case, the encoder (at a default effort setting) will detect this and use the jxl Palette transform to represent the image more compactly. In jxl, palettes can have arbitrary sizes, there is no limit to 256 colors. The --palette option in cjxl can be used to set the maximum number of colors for which it will still use the Palette transform — if the input image has more colors than that, it will not use Palette.
The use of Palette is considered an internal encoding tool in jxl, not part of the externally exposed image metadata. It can be used by the encoder to effectively recompress PNG8 files, but by no means will it necessarily always use that encoding tool when the input is PNG8, and it might also use Palette when the input has more than 256 colors. The Palette transform of jxl is quite versatile, it can also be applied to individual channels, to more or less than 3 channels, and palette entries can be not only specific colors but also so-called "delta palette entries" which are not a color but signed pixel values that get added to the predicted pixel value.
QUESTION
Sagemaker pipelines are rather unclear to me, I'm not experienced in the field of ML but I'm working on figuring out the pipeline definitions.
I have a few questions:
Is sagemaker pipelines a stand-alone service/feature? Because I don't see any option to create them through the console, though I do see CloudFormation and CDK resources.
Is a sagemaker pipeline essentially codepipeline? How do these integrate, how do these differ?
There's also a Python SDK, how does this differ from the CDK and CloudFormation?
I can't seem to find any examples besides the Python SDK usage, how come?
The docs and workshops seem only to properly describe the Python SDK usage,it would be really helpful if someone could clear this up for me!
...ANSWER
Answered 2022-Mar-22 at 22:39SageMaker has two things called Pipelines: Model Building Pipelines and Serial Inference Pipelines. I believe you're referring to the former
A model building pipeline defines steps in a machine learning workflow, such as pre-processing, hyperparameter tuning, batch transformations, and setting up endpoints
A serial inference pipeline is two or more SageMaker models run one after the other
A model building pipeline is defined in JSON, and is hosted/run in some sort of proprietary, serverless fashion by SageMaker
Is sagemaker pipelines a stand-alone service/feature? Because I don't see any option to create them through the console, though I do see CloudFormation and CDK resources.
You can create/modify them using the API, which can also be called via the CLI, Python SDK, or CloudFormation. These all use the AWS API under the hood
You can start/stop/view them in SageMaker Studio:

In the wonderful FBlazorShop
repo, Onur Gumus is riffing off of Steve Sanderson’s Pizza Workshop with F# flavor. On line 128 of blob/master/FBlazorShop.Web.BlazorClient/Home/Home.fs
[GitHub], Onur is passing an Elmish Message
for the parent, HomeView
, inheriting ElmishComponent
, to a child, PizzaConfigView
, inheriting ElmishComponent
. By convention, we can see Message
being converted (?) to PizzaConfigMsg

QUESTION
Im creating a workshop manual for my motorbike and my plan is to make the main window show drawn image of the bike (see example below, picture from google) and i would be able to click certain parts of the bike. Lets say i want to see information about the engine, i could click the engine and it would open up.
Should i create an image with transparent background for each part and put them on right spots in the software? If so, how do i make them clickable by "ignoring" the background so only the visible part would be clickable?

QUESTION
I'm working on a d3-force visualisation, which requires data in a specific shape. I've got an array of objects, each with an array of tags.
...ANSWER
Answered 2022-Mar-10 at 11:14You can use hash grouping approach. First make an object where keys are hashes of the links, and then use only the values as the result.
QUESTION
In my Workshop application, I would like to have a bar chart with a changeable x-axis. A dropdown widget would be used to select the desired x-axis.
For this I am writing a TypeScript function, that will return the data that will feed the chart widget.
I have wrote the following function:
...ANSWER
Answered 2022-Mar-03 at 10:44Some of the more powerful parts of Typescript's type-system allow us to specify a type-safe version of this aggregation function. I detail one approach to this in Part 1 below.
When exposing this type-safe aggregation function, we need to perform some additional checks because Functions doesn't currently support union types (see 'Functions API: Input and output types' in your Palantir documentation). I list my code for this in Part 2 below.
Part 1: A type-safe aggregationFirst, we list all the property API names that we'd like to group-by as a new union type of literal types. These should be the API names you'd normally use to access these properties in a Function.
QUESTION
I would like to know how can I filter on grouped data in Foundry Functions. I already managed to group and aggregate on my data, see below:
...ANSWER
Answered 2022-Feb-15 at 14:39You should be able to loop through the grouping
variable. You can always check what is inside with an old console.log(grouping)
and then preview.
It should look something like:
QUESTION
While looking at upskilling myself, I was watching the really quite excellent ggplot2 workshop to get myself better at using the package by understanding how it works at a fundamental level.
As part of that workshop, I was struck by one of the visualisations used in the workshop as being especially useful for explaining a layered hierarchy of dependencies, and I'm looking to figure out how I could generate such a picture (ideally using R).
These two pictures show the two parts of the visualisation I'm trying to reproduce: Stacked Planes with labels:
Stacked Planes, with transparencies for most, and labels (appropriately highlighted):
I have been able to produce something similar, using rgl, but it's not nearly as nice. Given I am trying to upskill myself in ggplot2, I would like to be able to produce it using ggplot2 (or one of it's extensions), as that would enable me to control some of the "nicities" of the graphic much easier).
Is this possible using ggplot2 or an extension package?
The code for producing it in rgl is:

QUESTION
Whenever I am trying to run the docker images, it is exiting in immediately.
...ANSWER
Answered 2021-Aug-22 at 15:41Since you're already using Docker
, I'd suggest using a multi-stage build. Using a standard docker image like golang
one can build an executable asset which is guaranteed to work with other docker linux images:
