I find it quite useful that I can do this in C:

I am learning Ada and I've hit a design problem. Excuse me as I'm not up with basic Ada mechanisms and idioms.

Let's say I want to represent an operation. Operators can be either plus or minus and operands can be either integers or strings.

Disclaimer: some things may not make much sense on a semantic level (minus on strings, operators without operands, ...) but it's all about representation.

For now I have the following incorrect code:

operand.ads:

I have a Pandas dataframe where I want to extract every word from the sentences in a column and create a new dataframe where each word has its own row. In addition, the original dataframe has a rating that should be added to the new rows.

The dataframe looks like this:

I come from a non-javascript coding background and one of the things that I am used to doing is encapsulating code in a class.

So I have a class file and it works but the constant reference to this. is lacks a certain elegance that makes me think that I am doing things the wrong way. Especially when I try to reference this. from within a "level" of code in a method and I have to carry the reference in a local variable to make it work.

So here is an example of what I have

I have thousands of images that need to be converted and combined into multiple PDF files. Some of the images are used multiple times. I'm looking for a solution to automate this.

I have all of the .tif files named and organized in a spreadsheet. I want to use that file list and run an automated script to save myself hundreds of hours converting these files one by one.

All the files are in the same folder.

I'm not a programmer. I've tried finding some kind of documentation, code, or third-party tool, but this seems to be an uncommon task. Thanks in advance.

I'm on Windows. Below is an example of the spreadsheet. I've got no problem using formulas to make whatever format or code I need in Excel. These files are individual pages of many scanned documents. "First Page" refers to the beginning of a section. Example: 0066.tif-0068.tif is one document where 0066.tif is the title page of the document. 0070.tif-0081.tif is THREE separate documents combined into one, with 0070.tif as the title page for all three. So it would be 0070.tif-0072.tif, 0070.tif & 0073.tif-0074.tif, and 0070.tif & 0075.tif-0081.tif. 0069.tif is a single page document.

Update: I'm sure this is rare. I found a solution, just in case there is someone out there with a similar situation.

I used a combination of Excel and nConvert. Still working on an easier/faster way to identify which pages are which, so for now that's still a mostly manual process. BUT, after I get that list made I used Excel formulas and VBA commands to export the list as a .bat file I can run to process all the files at once. Not sure if I am able to post files, but here is a the code output for the table of files I posted before, minus a few since this is getting lengthy:

Is there a way to convert an integer to an enum based on its value range? For the sake of elegance, I prefer to implement it into an enum or auxiliary type rather than as a separate function. Ideally, it would be great if I could perform the conversion using a cast like so:

I know my code is wrong. I should have uniform_int_distribution, but I need a random number generator that works whatever the type is. I mean I could generate int and divide them by 10^n to get a float but I dont like the elegance of it.

Suppose I am provided with an event producer API consisting of Start(), Pause(), and Resume() methods, and an ItemAvailable event. The producer itself is external code, and I have no control over its threading. A few items may still come through after Pause() is called (the producer is actually remote, so items may already be in flight over the network).

Suppose also that I am writing consumer code, where consumption may be slower than production.

Critical requirements are

1. The consumer event handler must not block the producer thread, and
2. All events must be processed (no data can be dropped).

I introduce a buffer into the consumer to smooth out some burstiness. But in the case of extended burstiness, I want to call Producer.Pause(), and then Resume() at an appropriate time, to avoid running out of memory at the consumer side.

I have a solution making use of Interlocked to increment and decrement a counter, which is compared to a threshold to decide whether it is time to Pause or Resume.

Question: Is there a better solution than the Interlocked counter (int current in the code below), in terms of efficiency (and elegance)?
