While playing the game War Thunder if you use the address http://localhost:8111 you can access a website that shows the current parameters of your plane that you are flying.
I want to access this data and automatically export it into files. For example the power performance of the engine at certain heights.
I use beautiful soup and urllib to access the data. However I have no clue how to send the data from my game with it. Without that however the website does not show any data.
Does anyone have an idea how I can send this data with my request?
If you're writing your script in Python, you can use this module. Once you have the data, you can write out the data like so:
with open('logger.txt','a') as outFile:
outFile.writelines(data)
Obviously, it'll take more effort to get things working, but it's a good start.

I built a WSGI page that contains both tabulated data and a scatterplot of the same data from a database. (I'm using flask and matplotlib but that doesn't matter). This generates two separate requests: One for the HTML page and one for the dynamically generated image called from the tag. Since the database is rather slow and since both requests need exactly the same data I'd like to make this work with just one SQL query. Two approaches come to mind:
After querying the DB in the HTML view function, generate the scatterplot and save that in a PNG file somewhere. Then pass the tabulated data on to the template and serve up the cached PNG once the browser requests the image.
Somehow embed the image data in the HTML itself and have the browser render it using Javascript.
Approach 1. is simple and straightforward, but I also need a way to get rid of the cached images when they are not needed any more. This is prone to get messy. Since the app is purely http-request driven I would have to scan my cache dir on each request and decide which file is old enough to be deleted. Alternatively I could have an "onload" javascript function call my app a third time to trigger deletion of the image. Maybe clever, but robust?
I have no idea how to do this, let alone in a browser-compatible way.
Any suggestions?
I've been on Usenet for 25 years and still posting a question is the best method to find the answer yourself after a few minutes:
<img src="data:image/png;base64, {{imgdata}}">
and in the view function:
return flask.render_template('chart_page.html', imgdata=base64.b64encode(pixbuf))
End of story. No javascript.
I have a bit of a situation. I was assigned a task to create a system that will take a KML file and update markers dynamically on a map. I'm currently generating the KML from a Wireshark Dissection and now need a way to take said data into a mapping tool. There are a few situations:
The PC that will be running the system will not have internet access, so I will need to cache de map data.
Each marker might move location so I need to erase said marker's previous location and update it with a new marker location. I do have a sequence ID I can identify it with, but I don't know how I'll update the new location.
It needs to be dynamically updated. A system will send data, my Wireshark Dissector will dissect the data and export it into a KML. This KML will need to be dynamically loaded into the system.
The basic idea in mind is like looking at Google Maps and watching your car move as it tracks your GPS location. But I need to make this tracking system work for a lot more targets than just one.
I'm sorry I currently have no foundation on where to start, but that's why I ask for your guidance. I've researched on ArcGIS, QGIS, Google Earth and Maps, but I haven't found a way to upload dynamically nor refresh the system.
Anything that could help me start finding a solution for this task will be appreciated.
Thank you for your time.
I had experience using leaflet js which allowed you to use bing map, google map, or opensource MapQuest to display mobile-track and car-tracking (for GM OnStar). I am also coding for kml to display flight-tracking on google earth now.
First, I am not sure it is possible or not :
you have a machine not connecting to internet
you want to use those map resource on internet
SO that I will assume that your machine can access internet. Then, there are many solutions.
You may try to see the simple tutorial on http://leafletjs.com/
You will have idea how to do it.
Plus, you have search for examples for Google earth (on which, I can display 3D tracking route).
Hope this help.
Other than map, see my sample to " Dynamic update data on Google Earth " in the following :
https://sites.google.com/site/canadadennischen888/home/kml/auto-refresh-3d-tracking
hope this help ....
(The following are copy from my link which talking about KML for 3D Google Earth. But I believe you can make it into 2D if you have to "not-use-google-earth".)

How to make a dynamic Auto refresh 3D Tracking :
prepare a RestFul service to generate KML file from DB
(sample as in https://sites.google.com/site/canadadennischen888/home/kml/3d-tracking)
My other jsp code will generate a KMZ file which has a link to my Restful service. KMZ file has onInterval ( as in the bottom)
Jsp web page allow user to download KMZ file.
When Google Earth open KMZ file, Google Earth will auto refresh to get new data from that Restful service
Everytime refreshing, server will send the latest update KML data with new data to GE.
KMZ sample:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2"
xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">

I tried to find this but I'm not exactly sure how to search for it or if it would even be possible. I'm trying to integrate a program I wrote with a commercial app, the commercial app has the ability to call an external program with a command and pass it the data that I want to capture.
I want to be able to get the currently open instance (or whichever responds first in the case of multiple instances) and send it the information directly and have it perform a function based on that information, I don't want to have to open a new instance.
I know one of my options is to drop a text file with the info and then have my program watch for it and parse it once found but if I can do a more direct communication I'd rather do that.
all it needs to do is fill a text box and run a function seems simple enough, and all I need is a point in the wright direction or some search terms that would pull up pertinent results. I'd like to understand how it works instead of just having someone write the code for me.
Thanks
I made a program that gets the data from the clipboard and saves it in a string variable. Then it looks for specific words in that string and generates several URLs. Afterwards it open the browser and shows each URL in an own tab.
Some of my friends already use this program frequently and I want to have some statistics about how often. I simple counter variable would be enough but I need to get access to it.
I came up with two options that could work:
I could send an email to a specific adress every time my app is executed. Then I can track the amount of uses by manually or automaticly counting the amount of emails in the postbox. I think this would be a Vers dirty solution.
I could create and publish a website containing a counter. This counter could be refreshed by my application. This solution is a bit better I think but a lot more work for just one single counter.
Do you have better ideas to solve my problem or is one of mine already a good one?
Thank you in advace!
You can use Measurement Protocol Overview. This provides you statistics of usage your application compared with Google Analytics. You can see even a geo statistic, version distribution, crash reports. It is easy to use it from .net. It is just about requesting http request to google.
I need to display pages in a tutorial fashion. I looked in to netsupport, beamyourscreen and other possibilities but, I do not want the viewers to download anything. I cannot use gd / send screenshots due to audio / video instructions embedded in some of the pages.
Basically, I need the ability to "refresh" a users browser window to a different page via an interface on my end. Whether via a form submission, javascript or any other type of "controller" that allows me to change the page on the viewers browser. PERL preferred but, PHP / javascript whatever works and is cross browser. I set up a simple javascript page forward timer that "works" but, page load times and conversation interruptions are a huge factor.
The entire tutorial website will be developed around this ability.
I was looking in to curl / cron / wget methods but, found little information.
I have seen forum and chat scripts that basically perform a similar task but, there must be a simple(ish) solution in leau of hacking up another script to suit my needs.
I do not want others to control the pages either. The site really, only needs to be accessable during the tutorial however, It "could" remain web accessable as long as user interaction was normal unless (being controlled).
The initial site concept is based on instructing people how to properly introduce new pets into a home. Will be operated by a veteranarian that saved my pets life. I wanted to give something back.
Possible? I really appreciate simple examples etc...
You have no other way but to keep polling the server for "instructions" using javascript. No, you can't send nothing to the end user browser, neither curl nor wget.
Mainly, you'll have to set up a simple request/response protocol between the browser and the server.
If you want to go deeper, you can use something like cometd/meteord/etc. If not, a hidden iframe that reloads himself and receives pages with javascript code for the needed actions can do the trick.
Another alternative.
With javascript dopolling and single character flatfile. Have a simple one character flatfile with a single var. Write it in perl (it is faster and uses less resources than php). The parent script calls a javascript variable in a flatfile. It hits the flatfile and goes wherever the var sets it. The flatfile is written to by the controller. Done.
I guess you could also rename an empty flatfile and use that as the controller. I am usure which is faster, open and read a specific file or hit the directory and return the file name. On the controller side, opening and writing to a file vs renaming a file. Maybe they counter each other in resources and time?
This way the site can act as a normal site. When you want to have remote users see a "presentation" (automatically being shown the site pages at the controllers pace), the controller activates polling and tells the viewers to push a start button. This allows a remote instructor to load pages for the viewers at his leisure.
It is a simple solution that works with nothing really sophisticated going on. No frames are needed either. Just need javascript enabled.
Any better suggestions are welcome!
It occurred to me that what you might want to use is HTML Push technology. Check out the wiki, they have several links. I have never used it myself
