cuts: Unix/POSIX cut (and paste) on (s)teroids. cut is a very useful Unix (and POSIX standard) utility designed to extract columns from files. Unfortunately, despite its usefulness and great popularity, it is pretty limited in power. Many questions on stackoverflow suggest that the same pain-points of the standard cut are felt by many users.

            Discord.py | When working with embeds, how does one use a for loop to generate a variable's worth of fields?
            Asked 2021-Jun-09 at 16:05

            I'm currently working on a discord.py dice roller command that allows one to input an argument for a number of dice to roll. As this command outputs to an embed, I would like each dice roll to output to it's own embed field using a for loop that executes the same number of times as the variable that contains the argument's amount of dice.

            I've attempted quite a few types of for loops, but I think I'm doing something fundamentally wrong. Unfortunately, Discord.py is not returning any errors when I run this for loop so I can't even begin to wrap my head around why...

            Counting total number of paper pieces
            Asked 2021-Jun-08 at 11:14

            The below is an interview question which I was unable to solve and needs some help.

            Question:

            A Person is playing with paper and during his game he folds the paper vertically in one turn and then horizontally in another turn and repeats the process n number of times. After he's done he cuts the paper vertically and horizontally. The task at hand is to take a number "N" as input and find the count of paper pieces that will be there after cutting the paper vertically and horizontally after folding it n times following the pattern as mentioned above.

            ...

            ANSWER

            Answered 2021-Jun-08 at 11:14

            As the comments mentions, you should look for a pattern in the sections (4 corners) and not in the total parts. We will enumerate the corners as a vector like this:

            (a (top left),b (top Right) ,c (bottom left) ,d (bottom Right))

            Also for sake of consistency and understanding we always fold from right to left in the vertical fold (right half on top of the left half) and from bottom to top in the horizontal fold (bottom half on top of the top half) and we start with horizontal as the first fold we will preform.

            first we start with 1 in each corner so when we divide we get the sum of all corners like this:

            (1,1,1,1) = 1 + 1 + 1 + 1 = 4 (n = 0)

            lets see what will happen in each corner after few runs:

            (2,1,2,1) = 2 + 1 + 2 + 1 = 6 (n = 1)

            (4,2,2,1) = 4 + 2 + 2 + 1 = 9 (n = 2)

            (6,3,4,2) = 6 + 3 + 4 + 2 = 15 (n = 3)

            (9,6,6,4) = 9 + 6 + 6 + 4 = 25 (n = 4)

            maybe at first its hard to see the relation between but actually the pattern is pretty simple:

            (a,b,c,d) -> (a+b,a,c+d,c) when you fold vertically (from right to left)

            and

            (a,b,c,d) -> (a+c,b+d,a,b) when you fold horizontally (from bottom to top)

            so you can get the recursive relationship and here some simple code in C for this:

            Linux shell - parse date in odd formats
            Asked 2021-Jun-04 at 17:03

            Is there any way to use standard tools (not programming scripts) to parse the date in custom, odd format?

            I've got a start script (bash) that should handle the output of the program, that contains dates with very odd formatting (like Jan, 4, 2021, 1:20:30 PM - which would be a pattern like "MMM, d, yyyy, h:mm:ss a".

            It would be possible to extract the tokens with sed or awk, but processing them is a nightmare, especially month shortcuts (they are in the same language like system, but that language can be installation-specific) or hours (need to check AM/PM token and add 12 if it's PM).

            'date' apparently doesn't support that, but maybe some shell extension or toolkit package? Or I'm out of luck and I need to parse this crappy format token by token with sed/cut/awk?

            This what I've tried was to do touch -d "Date" after removing the commas (so that I can compare dates with [[ file1 -ot file2 ]], but the problem is, that touch has ignored the TIME part, and ls -lh has shown, that the year was set in place of time, and the result of the comparison was therefore invalid.

            C threads corrupting each other
            Asked 2021-Jun-02 at 00:03

            So I've got a weird issue that I don't quite understand why it is happening. In md4checker, I launch n pthreads that get and check an MD4 hash. In md4.c, I generate an MD4 hash. If I set n threads to 1, it works flawlessly. It generates the MD4 hash with perfect accuracy (I ran it in a loop for 1,000,000 tries and not a single time did it fail). However, when I run this same code with n threads as 2 (or higher) it fails a lot and randomly.

            The md4.c file is derivative of another I found online but I tweaked it a little because the original md4.c had a memory leak (and running 50,000,000+ hashes made that leak fill up 16GB of RAM in about 15 minutes). If it was just a matter of it not working, I'd know where to start but I'm genuinely at a loss as to where and why multiple threads corrupt each other here.

            edit: If I add usleep(100) to the worker thread in md4checker.c, it cuts the failure rate to 10% of what it normally does.

            md4checker.c (works when running just one):

            Answered 2021-Jun-02 at 00:03

            So why the random number of fails?

            The MD4 code presented is not thread safe, and you are adding a bit of thread-unsafety of your own.

            Observe in particular variables A, B, C, and D in file md4.c. These are declared at file scope and without the _Thread_local qualifier, so they have static storage duration and are shared by all threads in the process. These are modified during the computation, so you have data races involving all of these. The resulting behavior is undefined, and it shouldn't be hard to imagine how it might mess things up if multiple threads were clobbering the values that each other had written in those variables.

            As for your own code, with each call to runprocs(), the main thread and each new one created all share the same struct data object, which the threads read and modify and the main thread reads, all without synchronization. This also causes undefined behavior, though it looks like this could be rescued by engaging a mutex or other synchronization mechanism.

            Additionally, the MD4 code appears to be deterministic -- given the same input, it will always (if run single-threaded to avoid undefined behavior) produce the same output. It is therefore unclear what you seek to accomplish by running it in multiple threads on the same input.

            Also, the while(!d.done) loop is pointless and poor form. You should be joining each thread via pthread_join() to clean up its resources after it, and since that has the (primary) effect of waiting for the thread to terminate, you don't need to also roll your own wait for termination.

            I made no effort to make cuts fast. Although compared to the I/O overhead, there may be not much need for it. If you have ideas on how to make the column extractions and joining more efficient, without compromising the simplicity, elegance and generality of the code, that would be welcome.
