stm | An R Package for the Structural Topic Model | Topic Modeling library

If you're using old a version of R that is 3.2 or Less then those versions does not handle Unicode in proper way. Try to install latest version of R from https://cran.r-project.org/ and if required then install all packages.

Accessing the individual bytes of a 32-bit integer is fine.

However, both of your approaches fail to work because you are passing the wrong memory address to HAL_SPI_Transmit(). You are passing the address of buf_ptr itself, rather than the address of OBuf that buf_ptr is pointing at.

Also, in the case of the second approach, you are not even assigning buf_ptr to point at a valid memory address to begin with! You are reading the values of the individual bytes of OBuf and casting them to pointers, rather than taking the address of each byte.

Try this instead:

0A decoded is \n or Line Feed; perhaps try sanitizing first with

The point of STM is to speculate: we try running all the transactions hoping that they do not conflict with one another (or perform a retry). When we do discover a conflict, we allow some transactions to commit, while making the conflicting ones to rollback.

We could run only one transaction, wait for it to complete or to block, and then run another one, and so on, but doing so would amount to use a single "global lock", making the computation completely sequential.

More technically, when threads are waiting on a MVar, those threads will progress on a very simple condition: the MVar becoming non empty. On wake up, a thread will take the value, making it empty. So, at most one thread can perform the take, and there's no point in waking more than one.

By constrast, when threads are waiting because of STM, the condition is much more complex. Suppose they are waiting because they previously performed a retry, so they are waiting for some previously read TVar to be changed. When that happens, we can't really know which thread will block again unless we re-run its transaction. Unlike MVar, it is now possible that waking them all up will cause all of them to complete without conflict, so we try doing just that. In doing so we hope for many (if not all) to complete, and prepare to rollback again for those that do not.

Consider this concrete STM example:

Here's the solution I'm using for this problem:

As u_mulder said in the comments,

your connect method will not return anything.

I updated it as below and made some change on your getData() method:

The fully qualified name of the table includes the database (schema) that it is in. So, if your database is named bobby and your table is named posts, you access that table using bobby.posts

Now, when connecting it is very common to specify the default schema, which you do. That saves the need to prepend the schema to the table name each time you name a table. However, internally, it is still used and for error messages it is very helpful to see the schema.

So when it says Table 'z7h5wlemxfp9e62l.post' doesn't exist that simply means the table post does not exist in database z7h5wlemxfp9e62l

The problem is first you request for going /dashboard.jsp page then you create session meanwhile, your label show previously created session because your page first load and then pass session...

it is mandatory to load page for get new session in java or any other programming

Use request.getRequestDispatcher() instead of getServletContext().getRequestDispatcher. rs.isBeforeFirst() is not for RowCount use of isBeforeFirst() is if data found pick first row...

here is modified code:

login.jsp

Spring Data Projections has many limitations and I think this is a perfect use case for Blaze-Persistence Entity Views.

I created the library to allow easy mapping between JPA models and custom interface or abstract class defined models, something like Spring Data Projections on steroids. The idea is that you define your target structure(domain model) the way you like and map attributes(getters) via JPQL expressions to the entity model.

A DTO model for your use case could look like the following with Blaze-Persistence Entity-Views:
