I have the following problem: Imagine I have a UTF8 file where every Special character is symbolized by the REPLACEMENT_CHARACTER "�". Some part of the file could look like:

Das hier r�ckg�ngig ist das zu machen r�ckg�ngig : ist bereits geamcht Weitere W�rter gibt ers zu korrigieren Hier noch ein bl�des Wort zwei in einer Zeile G�hte und Gr��e

I wrote a PowerShell script which replaces the REPLACEMENT_CHARCTERS by the corresponding Special characters, for example "a", "ü" or "ß". The corrected text, also UTF8, will look like:

Das hier rückgängig ist das zu machen rückgängig : ist bereits geamcht Weitere Wörter gibt ers zu korrigieren Hier noch ein blödes Wort zwei in einer Zeile Göhte und Größe

The Problem is that the program where I want the text to Import to only takes "Wester European DOS (CP850)" encoded files. By the way, that was the original coding which the program has been exported and would have imported without problems if I hadn't opened the file, edited it and saved it in UTF8. So here is what happend:

1. I exported files from a specific program as "Wester European DOS (CP850)". [Note: Every Special character has its own REPLACEMENT CHARACTER here, so an Import would work easy and restore the Special characters]

2. I opened the file with an Editor of my choice and the Editor detected "UTF8" on its own which is not correct. I did not recognize, edit the file and saved it as UTF8. [Now every Special character has the same REPLACEMENT CHARACTER, its �]

3. I have recognized that there is something wrong and wrote a script which replaces every occurrence of � by the right Special Character in UTF8. [I think it doesnt matter how the script does this, but if so, ask]

4. I have the corrected UTF8 File, but as you remember, I have to Import "Wester European DOS (CP850)" to my program. The same File Encoding as it has exported the file. This Encoding ensures that every Special character has its own unique REPLACEMENT_CHARACTER. So how do i got back to this by PowerShell?

Here are some more Information. The Line in which the script Reads in the file i want to correct is:

I am facing problem in getting values from rendered data in component that is already outputted on page render. What I need to do is, when someone types in data into text field, it should send it to database but taking that fields data from runtime data.

Currently, when I type something, it says undefined field etc. This is not form data but a data that need to be update from text field. So, if user write some xyz in text field, we need to update that data according to the id associated to that field.

I am not able to get data into: console.log(Id, projectId, userId, date, e.target.value) I have used reduce method that serves the purpose but now I have another use case.

I dont want to set hidden fields as its not the right approach.

The problem is that when someone type data in text field, I need to get that text field data and associated id and respective data from it and pass it ti ajax call.

I need to send that data with ajax but as soon as I type something, it says undefined. I can easily get data from projects array but its of no use to me. I think array reduce method is not good for my use case.

Here is project array:

Can anyone help in parsing this part of an HTML site? I use php and PHP:DOM I would like to get the Klassifikation and Schlagwörter in one php string. How is this done? Thanks

So, i am needing to replicate some data that already exists in a table. For example, a users table could have one user, but that one user may have 20 entries for 20 different accounts. So what i am currently doing when i have a new user that they say need to replcate a different user, is i am doing a insert into table_a (select from table_a where UserID = 'user to replicate). Now instaed of running this once for each entry, how can i tell it to loop through multiple rows returned, and insert for each one.

Example:

I wrote an ontology importer in Java to parse an RDF-formatted .owl file into a JSON-formatted string. More specifically, the static method parseOntologyObjectHierarchy parses the class hierarchy defined in the ontology into JSON. Everything works fine if I call the method from a JUnit test or the main method of a class (JUnit and the class main are invoked from IntelliJ IDEA Professional 2017). However, if I package my classes as a jar using gradle (including all dependencies), I get an org.semanticweb.owlapi.io.UnparsableOntologyException. The jar actually contains the required RDFXMLParser. Is the classpath in the jar not set properly?

I want to implement a fluid simulation. Something like this. The algorithm is not important. The important issue is that if we were to implement it in a pixel shader, it should be done in multiple passes.

The problem with the technique I used to do it is performance is very bad. I'll explain an overview of what's happening and the technique used for solving the calculation in one pass and then the timing information.

Overview:

We have a terrain and we want to rain over it and see the water flow. We have data on 1024x1024 textures. We have the height of terrain and the amount of water in each point. This is an iterative simulation. Iteration 1 gets terrain and water textures as input, calculates and then writes the results on terrain and water textures. Iteration 2 then runs and again changes textures a little bit more. After hundreds of iterations we have something like this:

In each iteration these stages happen:

1. Fetch terrain and water height.
2. Calculate Flow.
3. Write Flow value into groupshared memory.
4. Sync Group Memory
5. Read Flow value from groupshared memory for this thread and the threads in the left,right,top, and bottom of current thread.
6. Calculate new value for water based on Flow values read in previous step.
7. Write results to Terrain and Water textures.

So basically we fetch data, do calculate1, put calculate1 results to shared memory, sync, fetch from shared memory for current thread and neighbors, do calculate2 , and write results.

This is a clear pattern that happens in a very wide range of image processing problems. The classic solution would be a multi-pass shader but I did it in one pass compute shader to save bandwidth.

Technique:

I used the technique explained in Practical Rendering and Computation with Direct3D 11 chapter 12. Assume we want each thread group to be 16x16x1 threads. But because the second calculation needs neighbours too, we pad the pixels in each direction. meaning we'll have 18x18x1 thread groups. Because of this padding we will have valid neighbors in second calculation. Here is a picture showing padding. Yellow threads are the ones that need to be calculated and the red ones are in padding. They are part of thread group but we just use them for intermediate processing and won't save them to textures. Please note that in this picture the group with padding is 10x10x1 but our thread group is 18x18x1.

The process runs and returns correct result. The only problem is performance.

Timing: On system with Geforce GT 710 I run the simulation with 10000 iterations.

• It takes 60 seconds to run the full and correct simulation.
• If I don't pad borders and use 16x16x1 thread groups, The time will be 40 secs. Obviously the results are wrong.
• If I don't use groupshared memory and feed the second calculation with dummy values, the time would be 19 secs. The results are of course wrong.

Questions:

1. Is this the best technique to solve this problem? If we instead calculate in two different kernels, it would be faster. 2x19<60.
2. Why group shared memory is too damn slow?

Here is the compute shader code. It is the correct version that takes 60 sec:

I'm trying to follow the instruction on how to run a Spring application from command line: getting-started-cli-example. After I run the application by entering spring run app.groovy I got the following error:
