Faulty Url in FsLab package for F# - f#-data

I just downloaded this report called Analyzing and Visualizing Data with F# and am having a hard time just running the first example. This should probably be expected since the report is 7 years. I am running the first script which is as follows.
#load "packages/FsLab/FsLab.fsx"
open FSharp.Data
open XPlot.GoogleCharts
let wb = WorldBankData.GetDataContext()
wb.Countries
I get an error message that reads
Response from http://api.worldbank.org/country?per_page=1000&format=json&page=1:
{ "statusCode": 404, "message": "Resource not found" }
It looks like the url is broken because it seems that the worldbank has updated its api. When I use the url http://api.worldbank.org/v2/country in my browser it works. I noticed when I went to the source code that they have the base url hard coded in, so I was thinking I would just need to add "v2/" to it and it would work, but I am unfamiliar with how to load a edited library into my script.

Yes, your investigation is correct, even banks sometimes change their APIs :)
As for adding the library to your script, it depends on how your environment looks like, but basically you can fix the problem locally and/or globally.
For the local solution, once you compile your downloaded library with modified url, you can load or reference it as described here.
For the global solution, send a pull request that fixes the link in this file, Tomáš Petřiček (the repo owner) is generally active and should merge it. And you will improve the world a little bit.

Getting "'__name__' not in globals" when updating custom plugins for 2.0

I have updated my check_mk from 1.6.x to 2.0.x
My custom omd-plugins got messed up and so I started to refactor them for the new 2.0 API with the help of this article.
However, when the time for testing came, I got this:
OMD[my_omd]:~$ cmk --detect-plugins=my_plugin -vI my_host.my_company.de
Error in plugin file /omd/sites/my_omd/local/share/check_mk/checks/my_plugin: "'__name__' not in globals"
I was using sym-links.
For source-control, I have a git-repo. I had put sym-links pointing from the old checks-directory back to the plugin-file in that repo. Starting through the above mentioned guide, I created a new sym-link from the new local/lib/check_mk/base/plugins/agent_based/. Adding the required .py suffix in the process. So now I have 2 sym-links pointing to one piece of code, which I had modified in-place.
Turns out: If you do not delete the plugin from the old location, you will always test the old plugin. With sym-links, you will test the new code in the old environment, giving you that error.
Notice the path in the error-message!
As for the __name__ error itself: It seems to come from doing relative imports import .something. Notice the leading dot. It means "in the same directory as this file". Somehow the old environment was not able to cope with that.

Golem Task respons back with runtime error 2, can't determine the cause

Repo for all code I've been using is updated here . When I run the requestor script it exits with a runtime error 2 (File not found). I am not sure how to further debug this or fix it. So far I've converted my code over to a python slim docker image to better mirror the example. It also works for me when I spin up a docker image that typing and running "/golem/work/imageclassifier.py --trainmodel" works from root. I switched all my code to use absolute paths. I also did make sure the shebang (#!) uses linux end of file characters rather than windows before which was giving me errors. Fixed a bug where my script returns error code 2 when called with no args to now pass.
clf.fit(trainDataGlobal, trainLabelsGlobal)
pkl_file = "classifier.pkl"
with open(pkl_file, 'wb') as file:
pickle.dump(clf, file)
is the only piece I could think of that causes the issue, but as far as I can tell this is the proper way to pickle something in python. Requestor script is also heavily based on the simple service example and I tried to mirror my design to that. I just need help in getting more information while debugging, or guidance on how to move forward from here

uninitialized constant OrigenTesters

I am working on transferring one application from rgen to Origen.
I added environment/j750.rb in my application.
added the below code into j750.rb
# environment/j750.rb
$tester = OrigenTesters::J750.new
in Target folder, I also added $test as below:
$tester = OrigenTesters::J750.new
however, when I tried to generate pattern, it still failed and showed'uninitialized constant OrigenTesters'.
When and how to initialize it?
Thanks a lot in advance!
Normally this is something that Origen users don't particularly need to worry about, if you add:
gem 'origen_testers'
to your application's Gemfile, then it will be required automatically and a reference like OrigenTesters in your environment file or anywhere else will just work.
However, I note that you mention upgrading from an rgen app, which means that your application must be very old and in fact may not even have a Gemfile.
If you contact me internally I can send you the link to our intranet page which has a guide on how to update these really old apps.

What is the simplest way to create a UI test in Android Studio that can take screenshots when I need it to?

I am trying to create a UI test in Android Studio which will navigate through the various screens of my application and take screenshots when I tell it to.
I am new to Android Studio and Android programming in general; I have a decent understanding of XML and Java, but I don't know much about build files and I am not very good at using Android Studio, it seems.
I started this endeavor a couple weeks ago, and the first solution I tried was to use uiautomator. However, the documentation on that page (and seemingly just about everywhere else) is geared towards development with Eclipse, which I would like to avoid using for this project if possible.
The next thing I tried was Espresso. After I overcame some issues with implementing Espresso into my project, I was able to write tests with Espresso which would navigate through the screens of my application. However, unlike uiautomator, Espresso does not have built-in functionality to take screenshots at this time.
I first attempted to solve this problem of being unable to take screenshots with Espresso by writing custom code; as I'm still unfamiliar with Android, I wasn't really sure how to go about that, so I searched for help on the Internet (How to programmatically take a screenshot in Android?). However, I was unable to get the solutions I found to function from inside the test file.
Somebody recommended the usage of this tool: https://github.com/rtyley/android-screenshot-lib but I could not figure out how to import that into my project.
I eventually came back to uiautomator; I was still having a lot of trouble importing it into my project, and some people said that Robotium would help with that. I got Robotium to work, but I still could not import uiautomator.
It has been probably one month since I started using Android Studio, and in that time, I've had nothing but trouble simply getting the software to function properly. For the sake of brevity, I've omitted all the problems I have managed to solve on my own, but, to put it bluntly, I'm at the end of my patience.
TL;DR
If somebody could either:
-explain in the simplest possible way how to import uiautomator into an Android Studio project (I have read a lot of documentation about how to import external libraries into a project, but they all tell me to add a 'libs' folder to my project, but do not specify which type of folder to use [Java Resource Folder? Assets Folder? Module? etc.], and/or they tell me to go into Project Structure, select my app, go to dependencies, and choose "Import as Module," which does not work...)
OR
-explain how best to take a screenshot from inside of an Espresso test, including any instructions on how to import any required libraries
OR
-explain in detail some other way to create a UI test that can take screenshots...
...I would really appreciate it. I've spent days trying to figure out how to do this, and I am so frustrated. Many people have asked similar questions, but the answers are either too vague or the problems aren't close enough to my own.
Thanks!
Alright, after much trouble, I've found a very simple solution. It took me a very long time to work out, but if anyone else needs to do something similar, I'll put my conclusion here.
First of all, the testing framework that is easiest to use with Android Studio, it seems, is Espresso. Setting up Espresso is fairly simple; most of the instructions can be found here: https://code.google.com/p/android-test-kit/wiki/EspressoSetupInstructions Make sure you read it carefully -- it tells you basically everything you need to know, but I missed some important details and that caused me a lot of trouble.
If you browse around that Espresso site, it tells you just about everything you need to know about how to write Espresso tests. It was a little frustrating for me because, if I wrote a test and the test failed, my device would then have connection issues with my laptop and I would have to disconnect and reconnect the USB cord I was using. I think this had something to do with the fact that I was using a Nexus 7 with a Windows 8 laptop, which has given me some problems in other areas, so you may not encounter this issue yourself.
Now, unlike uiautomator, the documentation of which claims to have support for taking screenshots, Espresso does not have built-in support for taking screenshots. That means you'll have to figure out a different way to take screenshots. My solution was to create a new class (called HelperClass, in my case) inside my androidTest package and add this method to it.
public static void takeScreenshot(String name, Activity activity)
{
//slightly modified version of solution from http://www.ssaurel.com/blog/how-to-programmatically-take-a-screenshot-in-android/
//I added "/Pictures/" to my path because that's the folder where I wanted to store my screenshots -- you might not have that folder on your device, so you might want to replace "/Pictures/" with just "/" until you decide where you want to store the screenshots
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Pictures/" + name;
View v = activity.getWindow().getDecorView().getRootView();
v.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(v.getDrawingCache());
v.setDrawingCacheEnabled(false);
OutputStream out = null;
File imageFile = new File(path);
//the following line will help you find where the screen will be stored on your device
Log.v("Screenshot", "The image file path is " + imageFile.getPath());
try {
out = new FileOutputStream(imageFile);
// choose JPEG format
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
} catch (FileNotFoundException e) {
// manage exception
} catch (IOException e) {
// manage exception
} finally {
try {
if (out != null) {
out.close();
}
} catch (Exception exc) {
}
}
}
In order for this function to work, you will also have to add the following line to your manifest file.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Without that, the function above will throw a FileNotFoundException every time you run it.
Finally, to call the takeScreenshot function from inside your Espresso test code, use this line (assuming you called your class HelperClass... if not, use the name of your class instead.
HelperClass.takeScreenshot("Whatever you want to call the file", getActivity());
Finding where your screenshots are stored can be a little difficult if you don't know where to look. I added a line of code to the takeScreenshot function that would print the filepath to LogCat, but I was using the file explorer on my computer to look for the screenshots on my Nexus (which was, of course, connected to the computer), and I couldn't find that path. However, I got a file explorer application on my tablet which made it very easy to find where the files were located in relation to everything else.
My solution may not be the simplest and it certainly isn't the best -- you'll fill your device up with screenshots before long if you aren't careful to delete the ones you don't need anymore, and I haven't got any idea how one would go about saving the screenshots directly to, say, a computer connected to the tablet via USB. That would certainly be helpful. However, if you really need a simple UI test that takes screenshots, and you're frustrated to no end like I was, this solution should probably help. I certainly found it useful.
I hope this helps somebody else -- it definitely solved my problems, at least for now.
Of course if you don't have all the restrictions that I did when I had to write a UI test that took screenshots, the other posts in this thread probably work much better.
You should give AndroidViewClient/culebra a try. Using culebra GUI, you can automatically generate a test case that interacts with your app and takes screenshot exactly when you indicate so.

Auto-correlation callback function issue - loadrunner

I'm working in new application written in Siebel 8.1, issue appears when I'm trying to replay script and I can't handle that.
Replay Output:
Error -27086: Auto-correlation callback function
"flCorrelationCallbackParseWebPage" failed (rc=1) for parameter
"Siebel_Parse_Web_Page40"
web_reg_save_param("Siebel_Parse_Web_Page40",
"LB/IC=",
"RB/IC=",
"Ord=1",
"Search=Body",
"RelFrameId=1",
"AutoCorrelationFunction=flCorrelationCallbackParseWebPage",
"AutoCorrelationDll=LrwiSiebelCorrelationWrapper",
LAST);
I have done all steps for prepare record options from: http://software-qe.blogspot.se/2008/01/siebel-7x-record-and-replay-for.html
I'm using Loadrunner 11.52 (Siebel Web protocol), IE8.
We've been using the autocorrelation library for quite a few years on my team and we see this a lot. Unfortunately, it's not an easy problem to diagnose.
First I would check your test results and your VUser log to see if something happened before the autocorrelation failed. (Make sure your logging is set to parameter substitution in runtime settings).
Check your parameter files for extra spaces, commas, etc. Sometimes I've seen that error right after it rejects something about your parameter file.
Worst case scenario, your script is corrupted and you'll have to start over. We've gotten in the habit of making frequent backups of our scripts just because of this issue. Usually, we'll be able to start from our backup and continue or create a new script and paste the old code in. Autocorrelation error "magically" goes away with the same code in a new script.
If auto(magical)correlation does not work then use manual correlation.
Record twice with same data: Compare. You will find session, state and time data.
Change the credentials: Re-record. Compare. You will find credential related correlation
Change the business record but keep the same business process. Re-Record. You will find the business related correlation.
Do not expect autocorrelation to provide a magical working script. You have about a 0.0001% chance of that happening without LoadRunner script development intervenetion.
