QUESTION
With regards to qt_sequence_no_mnemonics(), the qt documentation says "This function is not declared in any of Qt's header files. To use it in your application, declare the function prototype before calling it."
But what does that mean? I only see this function declared in a cpp file that is not distributed. How do I declare that function, so that I can call it?
When I call it, is it on an instance of QKeySequence? Is it somehow static? Can someone help me understand what is meant by that documentation?
File here: https://code.woboq.org/qt5/qtbase/src/gui/kernel/qkeysequence.cpp.html
edit 1: I tried removing every import of QKeySequence, and walling that off behind a new file that does this:

QUESTION
I am currently working with the TC275 tricore chip, and am exploring the startup code taken from the example on Hightec free tricore entry toolchain. I'm wondering about the effect of square brackets in assembly statements. As I worked with ARM core before, when square brackets are surrounded by a register, it means a reference to the value that the address of that register is storing.
But for Tricore, for example with LEA instruction: "lea %a14, [%a14]lo:__crt0_config". This instruction means something like taking the low 16 bit value of the __crt0_config function address plus the low 16 bit value available in register a14 and then assigning it to the low 16 bit in register a14.
I refer to the documentation in the userguide of Hightec free tricore entry toolchain and it says:
Indirection: If an operand (register or constant) is used to access memory indirectly, you may, at your option, wrap it in square brackets (e.g. [r4]). This is completely in compliance with the specification mentioned above; however, there are no options which let you specify if the use of such indirection specifiers (read: square brackets) is illegal, optional, or mandatory. This means you can’t change the default, which is ”optional”. Of course, if you use indirection specifiers at places where they’re not allowed, you’ll get an error message, which again is compliant with the Assembler Mnemonics Specification.
In addition to the lea instruction, there are also ld.w and st.w instruction that also use square brackets (but the mov command does not). I think this is related to addressing mode.
Please help me understand the problem.
Thanks!!!

That's the same for TriCore
However, in ARM assembly language you would write [R4, #1234], in TriCore assembly language you would write [R4]1234.
So on an ARM CPU, you would write [R4, #lo:__crt0_config] instead of [R4]lo:__crt0_config.
Specifying a constant using lo:xxx is a feature of the tool chain, not of the CPU.
As far as I know, lo:xxx is the low 10 (not 16) bits of the address of the symbol (__crt0_config), sign-extended (this means: interpreted as signed 10-bit number).
And: TriCore does not have general-purpose registers (R0-R12), but it has registers only intended for data (D0-D15) and registers only intended for addresses (A0-A15).
In addition to the lea instruction, there are also ld.w and st.w instruction that also use square brackets (but the mov command does not). I think this is related to addressing mode.
Just like in ARM assembler, the brackets are used for memory addresses:
In ARM assembler, you write LDR R4, [R5] but you don't write MOV R4, [R5].
The LEA instruction (which also exists on x86 CPUs) is some "special case":
It takes a memory address as second argument and you can pass any valid memory addressing mode:
If the ARM CPU supported LEA, LEA R0, [R1] would be equal to MOV R0, R1.
However, for the second operand, you would have the same options as for the LDR instruction, so you could use LEA R0, [R1, #4]! or LEA R0, [R1], #4.
The LEA instruction is often used to do some "complex" calculations. In your case, it is simply mis-used instead of ADD because there is no ADD instruction that can add 10 bits to an address register.
I refer to the documentation in the userguide of Hightec ...

QUESTION
If you use FRED (https://fred.stlouisfed.org), you may have encountered the following situation: you have a data set of multiple series (say, 100 series), and you only want to retrieve those series that were updated in a specific timeframe (e.g. you check daily, and you only want to retrieve those series of your 100 that were updated today).
Fred offers the function fred/series/updates, described here in detail: https://fred.stlouisfed.org/docs/api/fred/series_updates.html
But, the series has a max. limit of 1000 results (or series), and once you use the function, you quickly realize that a typical call will return considerably more than 1000 results.
So, my question for FRED users: has anyone a good idea how to leverage this function? I'd really like to avoid having to do repeated calls to return the full list of updates (which one could do, I suppose, leveraging the "offset" parameter, but the volume of results returned defies the idea of minimizing data downloads). To the best of my knowledge you cannot pass a series of mnemonics and ask which of these have been updated.
So - what are ways you have found helpful for using fred/series/updates?
Thanks, Philipp
PS I'm leveraging R, but I suppose that the same issue may arise if you use python.
...ANSWER
Answered 2021-Oct-23 at 20:38I don't think there's a great answer here but there are some approaches that likely limit the number of calls you have to theoretically make.
Based on their API documentation, it seems you have no choice but to loop through all the results using the offset parameter.
You could limit results using the filter parameter if you know, a priori, that you are only interested in certain things. This isn't as ideal as being able to specify specific mnemonics, but it can help!
The docs say it limits to the last 2 weeks of updates and the results are sorted by the last update. If you track updates daily, you likely never have to go past "the first offset" on any given day (past the "genesis day") except on days the release is particularly large.
Do not take this as legal advice (I have not read their TOS)... but I do not think the total volume of calls you theoretically would make even if you downloaded the last 2 weeks of data daily would be considered "excessive" (in the grand scheme of things, even a few thousand JSON objects w/ 1000 entries each, as documented, isn't going to have an adverse effect on their bandwidth, especially if you rate limit your requests). That said, you can likely save yourself a large volume of calls.
QUESTION
Playing around a bit with Turbo Assembler and Turbo Debugger, I was surprised about opcodes. More precisely, I have some assembled binary in which Turbo Debugger disassembles the word
...ANSWER
Answered 2021-Aug-22 at 15:42Most x86 instructions support two operands of which one operand can be a memory operand. This is supported by encoding the operands in a modr/m byte. This byte always encodes one register operand and one register or memory (r/m) operand, but the instruction must decide which of its operands is the register operand and which is the memory operand.
So to support having the memory operand in the source or the destination operand, many instructions are available with one variant where the source operand can be a memory operand and one variant where the destination can be a memory operand. This is generally controlled by bit 01 (dubbed the d bit in some manuals).
As a consequence, instructions that do not need a memory operand can be encoded both ways and assemblers generally pick one or the other as a somewhat random implementation detail.

QUESTION
Apart from binary just being binary intrinsically (decimal notation, etc.) the binary sequences still have to be programmed to mean & initiate certain tasks. With that being said, & to be more specific/clarify:
How does one implement a custom assembly language with custom mnemonics starting from scratch, defining the values & definitions for the binary to execute specific tasks at specific address registers? (i.e. mapping keyboard keys, etc. then onto the assembly language, assembler, etc). (for implementation on a 64 bit computer).
In a nutshell, I'm inquiring about starting from scratch from binary. Essentially the lowest level of operations. Is a custom CPU/GPU necessary for this kind of implementation?
...ANSWER
Answered 2021-Jan-28 at 02:19So you ask about assembly language which is just a low level programming language often intended to have a direct relationship with a specific instruction set architecture (ISA or instruction set). If you are asking if you can make up an new instruction set for an existing ISA, absolutely nothing is stopping you from doing that instead of something like
QUESTION
Due to a known bug, JavaFX applications that use a MenuBar will keep the mnemonic selected ("latched") when the user presses Alt+Tab to switch to another program. When the user returns to the JavaFX application, the framework retains the latch.
ProblemIf the user then presses a letter that corresponds to the mnemonic, then the letter is consumed and that menu is opened.
This behaviour is not what users have come to expect from an application: it interrupts workflow. Rather, Alt+Tab should not put the application in a state whereby the menu can open. This is conflating Alt by itself to trigger the menu with Alt+Tab, a conceptually different operation.
Other questions seek to disable the mnemonic, but we want to clear the latch so that when the user returns to the application, pressing a letter will not trigger opening the menu.
QuestionHow do you instruct a JavaFX application to clear the latched mnemonics when Alt+Tab is pressed (i.e., the application focus is lost)?
...ANSWER
Answered 2021-Jan-24 at 01:08There are a couple of parts to this solution: releasing the mnemonics and consuming the Alt key press. Be sure to implement both.
Release mnemonicsOne way to work around the bug is to add a focus listener to the application's Stage that fires a key released event for all known mnemonics. Given a Stage instance, we can iterate over all the main menu mnemonics as follows:
QUESTION
When a .java file is compiled, it produces a .class file containing bytecode. JVM takes that bytecode and executes it. Byte during this step, if an exception is thrown, there is also a mention of in which line did this error occurred in source code. But the line numbers in bytecode and source code will be completely different and bytecode also does not store line numbers during compilation since I did not find any mnemonics related to it (and also storing line numbers would simply increase the code size). So can someone tell me how JVM gets the exact line number in the source code where the exception was thrown.
...ANSWER
Answered 2021-Jan-18 at 15:41The JVM specification provides a reference for the format of class files (bytecode). The line numbers are stored in an attribute LineNumberTable. You can also try running the following Java disassembler command (javap provided by the JDK) on a certain .class file to see them:
