How to use Material icons in Vaadin Flow (14.6)

Asked 2021-Jun-15 at 08:56

I'd like to use Material icons in a Vaadin 14.6 application. I found recipes for Lumo and Iron icons here (the default), but did not discover how to integrate Material icons. How can that be accomplished?

NB: This component seems to be not usable for Vaadin 14.x

ANSWER

Answered 2021-Jun-15 at 08:56

There are basically three approaches to this.

Easy approach

If you use only few icons. https://fonts.google.com/icons allows you to download each icon as svg or png file. So you can easily use those in Image component of Vaadin.

Light approach, use it as a font

There is training video at Vaadin's site which describes various things related to theming and styling of the app, at 19:30 timestamp there is a chapter about how to configure custom font:

https://vaadin.com/learn/training/v14-theming

Material icons are just a font, which you can include in your project.

Place the webfont files under e.g. "src/main/webapp/fonts/MaterialIcons" (note location is different if you have Spring Boot jar packaged project) and import the generated css

Your code is correct. And TreeTable does show all columns, you just miss the horizontal scroll at bottom of the grid.

To fix the situation, you need to

init UI in container ( currently it is atached to the body ). To do so you need to add container property to the UI configuration

QUESTION

How much quota cost does the LiveChatMessages.list method incur?

Asked 2021-May-29 at 04:55

I'm writing this app right now and one of its components is using the LiveChatMessages resource's list method to retrieve all the live chats in a stream. My issue is not with the functionality itself, the youtube documentation was quite clear regarding this (hats off to the youtube engineers if you're reading this).

My question instead is regarding the quota system. In my journey to figuring this out, I went to the holy grail of youtube data API quotas first aka the documentation. It led me to this page:

https://developers.google.com/youtube/v3/determine_quota_cost

Now, this has the information for all the quota for various Youtube Data API resources except for the LiveChatMessages resource. Ironically, the text at the top says:

YouTube Live Streaming API methods are, technically, part of the YouTube Data API, and calls to those methods also incur quota costs. As such, API methods for live streaming are also listed in the table.

And yet the table does not even mention anything regarding the LiveStreaming API. Now, I kind of just glossed past this and from the context of all the other methods and assumed that it only incurred one quota.

I ran my app on a mid-scale stream of around 500 viewers at the time and the quota ran out in way less time than I expected. Now, I'm not sure whether I understood the quota cost correctly or the LiveChatMessages.list method had a completely different quota system.

But my app queried the LiveChatMessages.list method every 5 seconds. Which meant that it would incur 12 quota costs every minute, 720 quotas cost every hour. And since I had a quota limit of 10,000. I assumed it would be able to handle over 13 hours of live streaming without the quota capping out. But instead, it would only be about a few hours before the quota capped over.

Anyways hopefully a youtube engineer sees this and can tell me what the quota mechanics are like for the LiveChatMessages.list method because the documentation does not really mention it.

...

ANSWER

Answered 2021-May-29 at 04:55

Short answer

By my calculation, the number of quota points consumed by a LiveChatMessages.list request is 5 points.

Explanation

The 5 point request cost is based on a back-calculation of the total query cost over one day of API access. A sample YouTube application looks for the latest live broadcast and retrieves all live messages from chat on a regular interval. After a day of running, visit the google cloud platform quotas section and identify the Queries per day quota of the YouTube Data API v3 service. This screenshot shows that the current usage of the daily quota is 8,180:

Now, visiting the YouTube API metrics, we can obtain a breakdown of the API calls by type:

num calls service call type 45 youtube.api.v3.V3DataLiveBroadcastService.List 1,627 youtube.api.v3.V3DataLiveChatMessageService.List

How do 45 + 1,627 = 8,180? 5 point factor for chat message list requests:

8,180 quota points = 5x(1627 message list requests) + 1x(45 broadcast requests)

Practical limits of the Youtube API 10,000 point quota

As I pointed out in the issue tracker, this limit seems lovw. For an application that interacts with live chat by making a request each 1s:

(10,000 points) / (5 pts/request) / (1 request/s) / (60 min/hr) = 33 minutes

Consider the extreme boundary case: if a live stream runs for 24 hrs/day, how many live chat requests can the quota support?

(5 pts/request) / (10,000 points/day) * (24 hr/day) * (3600 s/hr) = 43.2 s/request

QUESTION

BigQuery: user metadata described by start date and end date - Create permutations across multiple tables

Asked 2021-May-27 at 19:29

I have some BigQuery tables that contains some metadata related to an user, and the time interval on when that value is valid.

For example:

this table traces how the user color changes in time:

this table traces how the user fruits changes in time:

First, note that the time interval between the 2 tables are not equals, can partially overlap, overlap entirely or not overlap entirely, based on the nature of the single metadata

The goal here is to merge the metadata columns of the 2 table, in order to create a single table that ricreates the same structure of date start-end, while considering all the values and the date of each change.

So far I did this:

Asked 2021-May-23 at 03:40

Sorry for the choppy title, word limit (ironic). I've created a bot that responds with a randomly chosen string from a list when it's mentioned, pretty normal.

The thing is that most of the strings in my list are more than 280 chars, twitters word limit. Also the fact that the users twitter handle, the '@', and the space after the username (where the string should start) count towards the word limit

This is the code that I have come up with but I am stumped...

ANSWER

Answered 2021-May-23 at 03:40

This is a work in progress and needs some more testing based on your use case. I did some research and determine that the best way to split your long tweets would be with textwrap. This module will allow you to cleanly break your tweets into chunks.

I only attempted one tweet and one twitter handle in my tests, but I believe that the code below should work for your use case or give you a solid starting point to fit this functionality into your code.

Let me know if you have any questions about the code.

I'm pretty sure it is throwing an out of bounds error because you are deleting entries as you are iterating. You should trying running the loop in reverse: for(int i = myLines.size() - 1; i >= 0; i--)

Also I'm not sure why your for loops' upper bound is i < myLines.size() + 2; instead just .size()
