            Why joining structure-identic dataframes gives different results?
            Asked 2022-Mar-21 at 13:05

            Update: the root issue was a bug which was fixed in Spark 3.2.0.

            Input df structures are identic in both runs, but outputs are different. Only the second run returns desired result (df6). I know I can use aliases for dataframes which would return desired result.

            The question. What is the underlying Spark mechanics in creating df3? Spark reads df1.c1 == df2.c2 in the join's on clause, but it's evident that it does not pay attention to the dfs provided. What's under the hood there? How to anticipate such behaviour?

            Is Shannon-Fano coding ambiguous?
            Asked 2022-Mar-08 at 19:38
            In a nutshell:

            Is the Shannon-Fano coding as described in Fano's paper The Transmission of Information (1952) really ambiguous?

            In Detail:

            3 papers
            Claude E. Shannon published his famous paper A Mathematical Theory of Communication in July 1948. In this paper he invented the term bit as we know it today and he also defined what we call Shannon entropy today. And he also proposed an entropy based data compression algorithm in this paper. But Shannon's algorithm was so weak, that under certain circumstances the "compressed" messages could be even longer than in fix length coding. A few month later (March 1949) Robert M. Fano published an improved version of Shannons algorithm in the paper The Transmission of Information. 3 years after Fano (in September 1952) his student David A. Huffman published an even better version in his paper A Method for the Construction of Minimum-Redundancy Codes. Hoffman Coding is more efficient than its two predecessors and it is still used today. But my question is about the algorithm published by Fano which usually is called Shannon-Fano-Coding.

            The algorithm
            This description is based on the description from Wikipedia. Sorry, I did not fully read Fano's paper. I only browsed through it. It is 37 pages long and I really tried hard to find a passage where he talks about the topic of my question, but I could not find it. So, here is how Shannon-Fano encoding works:

            1. Count how often each character appears in the message.
            2. Sort all characters by frequency, characters with highest frequency on top of the list
            3. Divide the list into two parts, such that the sums of frequencies in both parts are as equal as possible. Add the bit 0 to one part and the bit 1 to the other part.
            4. Repeat step 3 on each part that contains 2 or more characters until all parts consist of only 1 character.
            5. Concatenate all bits from all rounds. This is the Shannon-Fano-code of that character.

            An example
            Let's execute this on a really tiny example (I think it's the smallest message where the problem appears). Here is the message to encode:

            To directly answer your question, without further elaboration about how to break ties, two different implementations of Shannon-Fano could produce different codes of different lengths for the same inputs.

            As @MattTimmermans noted in the comments, Shannon-Fano does not always produce optimal prefix-free codings the way that, say, Huffman coding does. It might therefore be helpful to think of it less as an algorithm and more of a heuristic - something that likely will produce a good code but isn't guaranteed to give an optimal solution. Many heuristics suffer from similar issues, where minor tweaks in the input or how ties are broken could result in different results. A good example of this is the greedy coloring algorithm for finding vertex colorings of graphs. The linked Wikipedia article includes an example in which changing the order in which nodes are visited by the same basic algorithm yields wildly different results.

            Even algorithms that produce optimal results, however, can sometimes produce different optimal results based on tiebreaks. Take Huffman coding, for example, which works by repeatedly finding the two lowest-weight trees assembled so far and merging them together. In the event that there are three or more trees at some intermediary step that are all tied for the same weight, different implementations of Huffman coding could produce different prefix-free codes based on which two they join together. The resulting trees would all be equally "good," though, in that they'd all produce outputs of the same length. (That's largely because, unlike Shannon-Fano, Huffman coding is guaranteed to produce an optimal encoding.)

            That being said, it's easy to adjust Shannon-Fano so that it always produces a consistent result. For example, you could say "in the event of a tie, choose the partition that puts fewer items into the top group," at which point you would always consistently produce the same coding. It wouldn't necessarily be an optimal encoding, but, then again, since Shannon-Fano was never guaranteed to do so, this is probably not a major concern.

            If, on the other hand, you're interested in the question of "when Shannon-Fano has to break a tie, how do I decide how to break the tie to produce the optimal solution?," then I'm not sure of a way to do this other than recursively trying both options and seeing which one is better, which in the worst case leads to exponentially-slow runtimes. But perhaps someone else here can find a way to do that>

            Implementing QQuickAsyncImageProvider in Pyside; No such signal QObject::finished()

            I'm attempting to implement a subclass of QQuickAsyncImageProvider in Pyside6, referring to the official example. I'm already aware of the potential hurdle that, unlike in the C++ example code, with PySide it's not possible to inherit from both QRunnable and QObject. In order to send a signal from my QRunnable I'm instead using an intermediary QObject, as suggested here. That part works fine.

            Equivalent of the Rstudio `browser()` function in Julia for debugging
            Asked 2022-Feb-11 at 13:20

            I wondered if there is an equivalent to the browser() statement available in RStudio for debugging purposes for Julia (I am using the Juno IDE at the moment).

            The R function browser() halts execution and invokes an environment browser when it is called. So, in principle, we can put browser() anywhere in our code to stop in this particular line and see what's stored in the environment at that moment, which is terrific for debugging purposes.

            For instance, the code below will stop when i>3. Hence, that's exactly what we will see in the environment browser available in RStudio, where we will observe that i=4 at that moment in the code.

            It is sometimes more convenient to choose in the source code when to break. This is done for instance in Matlab/Octave with keyboard, and in R with browser(). You can use the @bp macro to do this

            When does Linux x86-64 syscall clobber %r8, %r9 and %r10?
            Asked 2022-Jan-05 at 10:28

            I have just browsed the Linux kernel source tree and read the file tools/include/nolibc/nolibc.h.

            I saw the syscall in this file uses %r8, %r9 and %r10 in the clobber list.
            Also there is a comment that says:

            rcx and r8..r11 may be clobbered, others are preserved.

            As far as I know, syscall only clobbers %rax, %rcx and %r11 (and memory).

            Is there a real example of syscall that clobbers %r8, %r9 and %r10?

            ...

            ANSWER

            Answered 2022-Jan-05 at 10:28

            Only 32-bit system calls (e.g. via int 0x80) in 64-bit mode step on those registers, along with R11. (What happens if you use the 32-bit int 0x80 Linux ABI in 64-bit code?).

            syscall properly saves/restores all regs including R8, R9, and R10, so user-space using it can assume they keep their values, except the RAX return value. (The kernel's syscall entry point even saves RCX and R11, but at that point they've already been overwritten by the syscall instruction itself with the original RIP and before-masking RFLAGS value.)

            Those, with R11, are the non-legacy registers that are call-clobbered in the function-calling convention, so compiler-generated code for C functions inside the kernel naturally preserves R12-R15, even if an asm entry point didn't save them.

            Currently the 64-bit int 0x80 entry point just pushes 0 for the call-clobbered R8-R11 registers in the process-state struct that it will restore from before returning to user space, instead of the original register values.

            Historically, the int 0x80 entry point from 32-bit user-space didn't save/restore those registers at all. So their values were whatever compiler-generated kernel code left sitting around. This was thought to be innocent because 32-bit mode can't read those registers, until it was realized that user-space can far-jump to 64-bit mode, using the same CS value that the kernel uses for normal 64-bit user-space processes, selecting that system-wide GDT entry. So there was an actual info leak of kernel data, which was fixed by zeroing those registers.

            IDK whether there used to be or still is a separate entry point from 64-bit user-space vs. 32-bit, or how they differ in struct pt_regs layout. The historical situation where int 0x80 leaked r8..r11 wouldn't have made sense for 64-bit user-space; that leak would have been obvious. So if they're unified now, they must not have been in the past.
