How to load remote Maxima script? - webserver

I've written formula snippets containing user-defined functions (for example func-name(x,n):=x^2+x^3/n).
Now, I would like to share them with my colleagues.
What I am planning to do;
store snippet as .mac files
store files on https webserver
My question is, once the .mac files are on server, how can we access them remotely using Maxima?

PowerBI/Powershell - Get list of datasources that a PBIX file uses

I am trying to get a list of datasources that a Powerbi file is using. I seen solutions online where I can use the ReportingService module to get a list but this only works when the PowerBI report is published online. Is there a solution that would work for a local file?
Here is the situation.
A user gives me a Powerbi file. In order for me to get a list of datasources, I have to go in manually and to take a look at sources manually. Ideally, I would like to use Powershell to get this list.
There isn't an API that can access the desktop application. You would have to brute force it.
The PBX file is basically a Zip file which then contains separate files with JSON information. You would have to follow the following steps:
Use Expand-Archive to get the files out of the PBX (Not sure if you will need to change the file extension first).
Read the "Connections" file (Which is Json). It will have the various connection strings used by the model.
You can do this manually by changing the file extension to Zip and opening the Zip file directly, and looking at the connections file in notepad.

VS Code workspace storing additional script data

I wanna build external editor for scripts stored in crm.
I have API which exposes script engine returning list of scripts containing ,script id, script name, content...
Editor will be Visual Studio Code plus my extension. Manage to build extension and get data, store scripts on in the folder and give them name from the response. Problem is in update, to send data back to the server i need to use id not the name.
Question: is there any kind of container in workspace where i can store all data related to every script such as Id?
Something like settings for every script containing scriptName:id, date, owner...
Maybe https://code.visualstudio.com/api/extension-capabilities/common-capabilities#data-storage can help? You can store data either locally, in the workspace, or globally, in the user' storage space. Can be simple key/value pairs, or your own format.

How to Connect CloverETL to Google Cloud Storage?

I am using CloverETL Designer for ETL operations and I want to load some csv files from GCS to my Clover graph. I used FlatFileReader and tried to get file using remote File URL but it is not working. Can someone please detail the entire process here??
The path for file in GCS is
https://storage.cloud.google.com/PATH/Write_to_a_file.csv
And I need to get this csv file into the FlatFileReader in CloverETL Designer
You should use the Google Cloud Storage API to GET the file; Clover's HTTPConnector component will allow you to pass in the appropriate parameters to make a GET request (you will presumably have to do an OAuth2 authentication first to get a token), and send the output to a local destination specified in "Output File URL." Then you can use a FlatFileReader to read from that local file.
GCS has several different ways to download files from your buckets. You can use the console and the Cloud Storage browser. Steps: open the storage browser, navigate to the object you want to download, right click, and save to your chosen local folder. If you use Chrome the save appears as “Save Link As…”.
To use the GS Utility, use this command:
`gsutil cp gs://[BucketName]/[ObjectName] [ObjectDestination]`.
Or you can use client libraries or the REST APIs to download files. With these last options you could work with a number of files or create a job to download them. Once they are in a location known to Clover ETL the process is straightforward.
Within Clover designer, under the navigation pane you can right click a folder and choose import. Pick the one in which you placed your GCS file. Once the file is imported then you can use data from it like any other datafile in Clover. Since this is a .csv file, remember to edit your metadata (right click the component, choose extract metadata then edit inside the Metadata Editor -- for data types, labels and such.) Assign metadata to the edges of your components so they know what is coming in/going out of that step. Depending on your file, this process may be repeated many times.
Even with an ETL tool, getting the data and data types correct can be tricky. If you have questions about how to configure data types or your edges in an ETL project, a wiki may help. The web has additional resources may help you get the end analysis you’re looking for.

TFS 2013 build - uploading build output to servier via FTP

I'm hoping someone can help. I've started using the Community TFS Build Extensions, in particular the FTP activity. I followed the documentation here and got to grips with the it pretty easily. I'm encountering one major problem though.
My Web app has a basic enough structure:
I start by creating the FindMatchingFile activity which places the files in the drop location into an IEnumberable variable called FilesToFTP :
String.Format("{0}\**\*.*", BuildDetail.DropLocation)
When I iterate through the variable and print out the results, all seems correct:
G:\builds\Build.1203\CredentialManagement\bin\BusLogic.dll
G:\builds\Build.1203\CredentialManagement\css\style.css
G:\builds\Build.1203\CredentialManagement\AppError.aspx
......
G:\builds\Build.1203\CredentialManagement\Web.config
etc etc.
The problem is, when I pass that IEnumerable to the Ftp activity (converting it to a string array), it FTP uploads all the files on the server however it doesn't keep the directory structure of my Web app. It just piles all the output (dlls, aspx etc) into one directory. See the following two screenshots.
Is there any way I can use the FTP activity to upload all the output from the drop location recursively? I feel like I'm doing something simple wrong.
The FTP activity in TFS Build Extensions doesn't upload files recursively.
I think it would be a good value addition to the activity. Please create a request for the project and we will add in it. For now, you can go around it by calling the Ftp activity recursively for each directory and setting the RemoteDirectory for each.

Non class files with Java Web Start

How do you distribute other files needed by your application that aren't in a jar file? For example, the application at http://www.javabeginner.com/java-swing/java-swing-shuffle-game . The download contains Shuffle.jar, Shuffle.bat, Score.dat, and an images folder with 3 images in it. I can see possibly putting the images directly in Shuffle.jar, but you wouldn't want to put Score.dat in the jar file because it changes. Is there somewhere you could identify this type of file in the jnlp?
The non-java files should be stored as resources. For files that change, you store the original or template file also as a resource in your jar. When the program starts, you have it check the local system to see if that file exists. If not, it creates the local file by copying the template file from the JAR resource. If the file already exists, then it is used as is.
To save files to the local system, even when running in the sandbox (unsigned), you can use the PersistenceService (javadoc / example). If your java application is signed, then you can use the regular File apis to write the file to the local machine, such as in a ".yourgame" subfolder under the user's home folder.
You can put all those files (except the scores file) in your jar file and load the contents using resource loading.
I've just deleted and restarted my reply twice now, changing my answer each time; this is confusing and needs a bit more clarification.
Are you SURE that application is supposed to be a Web Start app? On the site you linked to, it doesn't appear to be. Are you trying to take an application that was not designed as a Web Start application and change it into one that can be Web Start?
If it's not a Web Start app as your tag implies, then this question is open ended. You can distribute it 100 different ways.
If you are indeed trying to convert it into a Web Start app, you can start by packaging the images into the jar and that will alleviate your first headache if you just read them from there instead of from a File(). If it's going to be Web Start, then you need to decide how you want to keep scores. You have to decide what the scoring system is like before you can decide on how to go about it; will all the scores be kept on the web site hosting the Web Start app? Will that part still be local? If you want to get access to the local file system, you need to sign the jar, then you can extract the score.dat to the file system and do whatever you want with it if the end user accepts.
You need to figure out what you want to do before you can do it, or at least clear it up for us if you already know more than we know you know.
