Moving toward Apache Beam 2.x, I want to use templates as much as possible, and ValueProvider accordingly.
In my logic, I am using a FixedWindow, but the duration is flexible, so I rather get it from a ValueProvider.
The problem is that FixedWindows.of() only get Duration, and I failed to find a simple way to grab a ValueProvider and make a duration out of it.
Please advise,
Shushu
Unfortunately this question has a simple answer: this is currently not supported. Feel free to file a JIRA - it seems like a reasonable request.
Ran into this exact issue today but with SlidingWindows, we just wrote our own windowing function with a new param that was a ValueProvider instead (similar to https://github.com/apache/beam/pull/3358/files) and this seems to work.

As part of the new updates, Roblox has decided to remove the Velocity component. Anyone know any work-arounds?
Sorry if this response is late, however I guess it's not too late to answer, since nobody has.
A roblox staff member has confirmed that a solution to replacing the Velocity component is .GetVelocityByPosition(), however you probably want to use .AssemblyLinearVelocity() or .AssemblyAngularVelocity(), all of this really depends on the context you are using it.
I also want to clarify, depreciation does not mean you can't use it anymore, it usually means that you are better off not using it, however, just go by the solution, it's better that way if you do.
I was doing web scraper but then I got blocked for too much commands and someone said I should retriev the json itself with this url and try play with it :https://steamcommunity.com/market/search/render/?query=&start=1490&count=10&search_descriptions=0&sort_column=price&sort_dir=desc&appid=730&norender=1
and I changed it to this :https://steamcommunity.com/market/search/render/?query=&start=0&count=100&search_descriptions=0&appid=730&norender=1 but when I try to do more than 100 it doesn't give me more outputs is there a way to fix this? Btw Iam new to programing and stuff, so I dont know much.
Short answer: no.
These query parameters are most likely limited by Valve itself. Also, WebScraping / Crawling has the huge disadvantage that many or even most providers are actually blocking requests after a determined amount of requests / after a distinct use pattern whatsoever.
The only way to counteract this is to use an official API. By now, there's no such thing though.
I want to simulate lidars. I saw that a class DepthSensor was mentioned in the documentation, but I have not found its actual implementation. For now, I am planning on using the RgbdSensor class and use only the height I need of the depth point cloud I receive to simulate my lidars.
Just to get your input on that, maybe I missed something, but is there a specific class for lidars, and how would you go about adding lidars to a simulation?
Thanks in advance,
Arnaud
You've discovered an anchronism in the code. There had previously been a lidar-like sensor (called DepthSensor). The extant documentation refers to that class. The class's removal should've been accompanied by a clean up of the documentation.
The approach you are taking is the expected approach given Drake's current state.
There has always been an intention to re-introduce a lidar-like sensor in Drake's current architecture. It simply hasn't been a high priority.
I'd recommend you proceed with what you're currently doing (lidar from depth images) but, at the same time, post an issue requesting a lidar-like query with specific focus on the minimum lidar-properties that you require. A discussion regarding how that would differ from what you can actually get from the depth images would better inform of us your unique needs and how to prioritize it. (You can also indicate more advanced features that you need less but would be good to have, of course).
As for the question: how would you go about adding lidars?
That's problematic. Ideally, what you would need is ray-casting ability. The intent is for QueryObject to support such a query, but it hasn't happened yet. (It's certainly the underlying technology we'd have used to implement a LidarSensor.) In the absence of that kind of functionality, you'd essentially have to do it yourself in the most horrible, tedious way imaginable. I'd go so far as to suggest that it's not feasible with the current API.
I am looking for a quite specific tool for generating charts, within Ruby on Rails application. I have done a research and couldn't find a solution that suits me.
Maybe you've bumped upon it and could just point me to it with a link? :)
My requirements for a solution are:
it has to feature basic chart types
like Pie, Bar, Stacked Bar, Line.
it has to have basic configuration of
a chart like legend, axis
description.
it has to be able to generate and save chart into image file without
actually rendering it in a browser
being a Ruby library would be nice,
but it is not obligatory
not being Gruff Graphing Library, I
am looking for something more up to
date, with less issues.
If you are aware about something, please post a link - it'll take you just a few seconds.
I think, that it is what you're looking for.

I've made a number of useful charts with the Google Chart API. There are a few gems: googlecharts, gchartrb. I haven't used them but they look like a good first cut.
As to not displaying it you can just make the call and save the result. No need to render, just make the call, get the URL, and fetch the file.
The only one that has satisfied all these conditions:
I have been able to make it works without need of install weird dependencies
Not has an HTML context requirement (all JS libraries)
Not depends on GCharts (net traffic dependency)
Exports to static graphic format
is gerbilcharts
Chartkick!!!
It's super nice. =)
It's been a long time since I asked this question and I see new people coming and posting new answers, which his great. This small post of mine turned out to be a small compendium of available libraries.
I decided to add my two cents. Nowadays whenever I am dealing with charts I usually use Highcharts. Highcharts is a very pleasant library by itself, but additionally there is incredible gem highcharts_on_rails which facilitates creating charts using DSL written in Ruby.
If you found this question and you're looking for options, consider highcharts_on_rails.
This might be able to do what you want:
Gruff
You can use rchart for plotting various chart.
I am using openflashchart
http://pullmonkey.com/projects/open_flash_chart2/
you can save generated json data in database and render when needed
I need to be able to find the current time from an online source rather than the system to make sure the time is correct. I need to do this in actionscript, preferably 2 rather than 3 though if you have any solution at all post it. Thanks ahead of time for the help.
Here's a possible reference: http://board.flashkit.com/board/showthread.php?t=663535
The easiest is solution is probably as above, to create a server-side script to return the time and then fetch that in your ActionScript.
Another option is to create an NTP client in ActionScript. Unfortunately it's been a while since I've done any ActionScript, but here's a straightforward example in Python if anyone wants to do a port: http://maxinbjohn.blog.com/2366141/
