QUESTION
I'm confused about the use of "&" when examining a label using GDB.
I'm following a book from 2008. The author's debugger apparently shows the value stored at the label. However, I can't get the same debugger and am using GDB. I found somewhere that I can see the value using:
...ANSWER
Answered 2022-Apr-02 at 03:55GDB is not just an asm debugger, and is in fact primarily designed to debug compiled C programs and stuff like that. And its treatment of variable names / labels is designed around C variable-name semantics, not asm label semantics.
If GDB doesn't have symbol-type information, it doesn't know whether it should have value semantics like a C int
global variable, where using the bare name loads from that address (with some width that's also unknown to GDB), or like a C array where using the bare name decays to the address (in most contexts). Or whether it's a code label.
Older GDB I think used to have a default, but current GDB doesn't.
You're correct that an asm label is best thought of as having semantics like C char label[]
(at global scope).
Especially in NASM syntax where mov reg, name
is a mov-immediate of the absolute address, unlike GAS .intel_syntax noprefix
where it's a load, like MASM.
For more philosophical musings about the meaning of life (for an asm label), see Is every variable and register name just a pointer in NASM Assembly?
If you're debugging a program compiled from C with debug info which does define a char foo[8] = {1,2,3};
you should be able to use x /8c foo
to see the contents of memory there.
Indeed, I tested that and it works with this C program, on x86-64 Arch GNU/Linux
QUESTION
I have a dataset where I'm trying to make 3 graphs for the same variable (Den Volume) grouped by Species Group. I factorize the Species Group Column to control the order of the display, but the color order is not preserved between line and fill.
Here's the code snippet:
...ANSWER
Answered 2022-Mar-24 at 19:30The issue is that ggthemr("flat")
overrides the default ggplot2 color palettes. However, looks like that does not work in all instances.
But according to the docs
To avoid this and keep using ggthemr colours in these instances, please add a scale_colour_ggthemr_d() layer to your ggplot call.
Hence, adding scale_colour_ggthemr_d()
instead of scale_color_discrete
fixes your issue:

QUESTION
I recently went through a tutorial on building a menu that I wanted to use for a site I'm putting together. The functionality seems to be working but the issue I'm having is with the 'leftIcon' for the 'My Profile' section. I believe the 'leftIcon' is only meant to take a *.svg file and was wondering how I would go about seeing the imported {avatar} .jpg as the left icon.
I have attached a copy of the files below and really appreciate any input on the matter.

QUESTION
I have compiled CLIPS 6.4 into a shared library (compiled as C++) so that I can use in a C++ application.
I want to now write a simple test C++ application that allows me to:
- Start up the CLIPS engine
- Load a CLIPS program (see animal.clp)
- Assert a fact from the C++ program to the CLIPS engine and receive responses back from CLIPS in my C++ program
- Safely terminate the CLIPS engine and cleanup when nothing on the agenda (all rules fired) - i.e. program completed
ANSWER
Answered 2021-Oct-14 at 20:09The CLIPS Advanced Programming Guide is here: http://clipsrules.sourceforge.net/documentation/v640/apg.pdf
You can use the Load function (section 3.2.2) to load a file. There is an example of its use in section 3.6.1.
You can use the GetNextActivation function (section 12.7.1) to determine if the agenda has any activations.
The simplest way to create facts is using the AssertString function (section 3.3.1). Sections 3.6.2, 4.5.4, and 5.3 have an example use of this function. You can also use the FactBuilder functions described in section 7.1 (with an example in section 7.6.1).
If the results of your program running are represented by facts, you can use the fact query functions via the Eval function to retrieve those values from your program. Section 4.5.4 has an example.

I have two dataframes The first is a key with a list of ids. The second dataframe is a table containing values for each of the ids. I'd like to sort the list of ids in the first table with values from the second DF.
For example here is DF 1:

Answered 2021-Sep-27 at 14:13UPDATE: You can explode the list, join it to the sorting DF to have the order column, and then use windowing to collect the list back in order:

and DF2 is (name: String, ord: Int)

QUESTION
I have the following array in C (Used random names)
...ANSWER
Answered 2021-Jul-18 at 06:11There are two problems in your code -
- In function
ArrSwap()
you are looping over index 0 to 5. So, wheni
becomes5
,Arr[i+1]
points toArr[6]
which leads to read from a memory past your array bounds. Which is undefined behavior. - Secondly, if I get your requirement correctly, you want to swap the first and second elements swapped, then third and fourth and so on. So, your code has a logic error. In that case, in
ArrSwap()
the loop needs to increment by 2 instead of 1.
So the code may look like this after both issues are addressed -

HelloWorld! First of all, I'm new to the English version of this page. I think my English is good, but if make any mistakes let me know and I'll fix it. Second, the code I wrote (I'll show you in a minute) is probably not the most efficient, but I only want it to work. Here's the thing...
I'm practicing with kivy and I decided to make a program which will create an anagram out of a list of words, the user will have to guess the word and the program will tell if it is correct or not. I made a program that does that, but I was having problems with the 'new word' button (a new game, so to speak), so I've decided to make a new code (I'll show you the old version in a comment). And this new code fails from the beginning. When I add the labels and buttons, not only I can't click on them, but they are also shown on the bottom-left part of the screen, and very small. The image shows the result: Labels, Buttons and RelativeLayout.
