So, I'm using FlatFileItemWriter to write a csv file from data that I can successfully read from a database.

I'm struggling with how to write an integer number (i.e., row counter) corresponding to the row that I'm writing to the file. Seems like an easy thing to do, but quite simply I am stumped.

Everything is working (file is being produced from the data being read from a database). But I just can't seem to figure out how to implement my getCount() method in a way that gets me the corresponding row's count. I'm thinking it has something to do with leveraging the ChunkContext, but I can't seem to figure it out.

So I have the following in bean in my job configuration.

I have search field that filter my list and it works fine I just want to make small changes to it:

Logic

1. Back to full list when user clear search field
2. search also be included of ListTile->subtitle currently only search in title

Code search function is commented for better understanding

I was designing a database model using chen notation, but there's one part where I'm not sure how it will looks like in crow's foot notation. As far as I know, a new relation needs to be created when the relationship between two entities is many to many, which looks something like this:

However, I'm creating a new relation for entities with one to many relationship as I'm adding attribute for the relationship. Therefore, I'm not really sure on how it will looks in crow's foot notation.

The primary key for book and publisher is just bookID and publisher ID

Basically, I'm trying to modify the accepted response to this question to retain the id field which is used in the aggregation.

So if my input dataframe looks like this:

Considering the following SO Question: Is it dangerous to use synchronize in a non-VCL application?

I was wondering how TThread's Synchronize, CheckSynchronize and WaitFor is affected when using them inside an Apache Web Application DLL.

I started investigating this when I realized WaitFor was locking/hanging. Inside WaitFor it checks if CurrentThread.ThreadID = MainThreadID and then repeats checking the result of MsgWaitForMultipleObjects and based on the result it will do CheckSynchronize or PeekMessage and when it received a WAIT_OBJECT_0 it will finally exit the loop. If the MainThreadID is not the same as the CurrentThreadID, then WaitFor will do a single WaitForSingleObject.

So I created the following test Apache Web Module DLL to see what the MainThreadID is during the lifetime of a web request.

I need to conditionally bold text inside of an Excel spreadsheet. The logic is as follows:

For each record, I need to bold the last name first initial in column E that corresponds with the name of the person in column B (which is formatted Last Name, First Name). All the last name first initial are separated by commas in column E. Note that there might be two of the same last name with a different first initial in column E. I need to iterate through a spreadsheet with 1,000+ records. Example below:

A B C D E value Smith, Joseph value value Jones K, Jenkins T, Smith J, Hines L, Abdhel B, Higgins M value Roberts, Anna value value Taylor B, Starbert K, Helmann E, Santoro P, Stebnitz M, Hamilton A, Brown P, Palmer A, Roberts A, Stanton J value Chen, Jennifer value value Anderson B, Chen J, Flanders C, Chen P, Aberdeen T, Daniels P

• For the first record, "Smith J" in column E must be made bold based on the "Smith, Joseph" in column B.
• For the second record, "Roberts A" in column E must be made bold based on the "Roberts, Anna" in column B.
• For the thrid record, "Chen J" must be made bold base on the "Chen, Jennifer" in column B -- PLEASE NOTE that there is another "Chen" ("Chen P"), in column E that must not be made bold.

I greatly appreciate any help.

I'm trying to calculate the centroid of a 3D mesh of triangles.

EDIT : it turns out I was not, I was trying to calculate the center of gravity, which is not the same

My code is made of bits and pieces, mainly :

• This nice paper by Cha Zhang and Tsuhan Chen
• SO : How to calculate the volume of a 3D mesh object the surface of which is made up triangles
• SO : How to compute the centroid of a mesh with triangular faces?

I compared my results to those provided by Rhino. I calculate the centroid and volume :

• of the reference NURBS volume with Rhino 7
• of a 27k triangle mesh with Rhino 7
• of a simplified 1k triangle mesh with Rhino 7
• of the same 1k triangle mesh with my code.

As you can see, it works great to calculate the volume, but not for the centroid, and i can't seem to know why. I need the error to be less than 0.01. I checked everything several times, but there must be something obvious.

I'm not great with numerical instability :

• should I work in milimeters instead of meters ?
• should I calculate the tetrahedrons signed volume with another point than the origin, as suggested by galinette in the second reference ? I tried and it didn't improve much.

MY CODE

Before calculationg anything, I check that my mesh is correct (code not provided) :

• closed mesh, no naked edges or any holes ;
• the vertices of all triangles are ordered consistently, i.e. triangles are correctly oriented towards the outside of the mesh.

I developed a 3D cube that moves on one axis simulating the accelerometer sensor. Currently, I have the .obj and .mtl of a toycar which I aim to add to the scene(), but when I remove the BoxGeometry 3D cube and replace it with the car mesh I got these errors all the time:

I also get this error saying that obj is not defined, even if I defined it globally I still have the same issue:

I checked libraries that exist locally and other function but I can't see where is the problem.

Below is how I load the car model:
