ANSWER
Answered 2020-Apr-04 at 16:39As Peter Cordes correctly said, your program would fall off _start
and return to undefined code, if it didn't crash earlier due to infinite recursion in printi
.
The reason there is infinite recursion: you probably think that div ebx
divides EAX
by 10. It doesn't: it divides EDX:EAX
64-bit value by EBX
, and you don't control EDX
.
Zeroing out EDX
before DIV
allows the program to print something (but not the desired output), then crash when it falls off printi
.
QUESTION
I was playing around in Python as I am relatively new to it. Below is a snippet
...ANSWER
Answered 2019-Dec-12 at 14:44Classes are first-class objects in Python; you can pass references to them around.
Person
is a reference to the class defined by the class
statement. Person()
(calling the class
object like a function) returns an instance of that class.
Attribute lookup rules can get complicated, but for this example the following simplification will suffice. Since neither new_person.version
nor another_one.version
is defined, an attempt to look either one up will result in a class attribute lookup. That is, new_person.version == type(new_person).version
.
If you create an instance attribute with the same name, it will shadow the class attribute:
QUESTION
Hello I want to know how to load a Dialog Topic file using python. I made sure that the file path is right, but it keeps saying that it isn't. I have also used the tutorials in NAO 2.1's documentation ALDialog and ALModule Please send me a code that works or tell me the error. I tried using the following code:
...ANSWER
Answered 2018-Oct-25 at 18:41The path to the topic needs to be the absolute path to that file, whereas you're passing a relative path compared to your current execution directory. The reason is that ALDialog is a separate service running in it's own process and knows nothing about the execution context of whoever is calling it.
And the program .top file must be uploaded to the robot using Choregraphe.
So, your absolute path in this case might be something like

TD:DR, jump to EDIT5.
I'm trying to writte some Greek text into a pdf form via iText. I'm retrieving the string from the DB, where is in Greek, but when I try to print it into the pdf form, it shows nothing (the pdf is also Greek-written). I've tried almost everything I've found, same in here, same in iText forum.
As you can see, the string is in greek:
but it is not written into the pdf:
EDIT:
I've lost count how the efforts trying to make this happen. Converting the string to an array of bytes and then coding it back was one of the closest aproches i could make. Sadly, there is no much code to be shown. As told befor, i've got an string qich has the dfata shown and when traying to printi it into dthe pdf form with a sentence like form.getField("municipality").setValue(municipio);
the output is, again, the shown.
EDIT2:
Using itext 7.0.4, now we can't create the font, as nor baseforn nor font classes are beeing recogniced as itext classes.
...ANSWER
Answered 2018-Jul-23 at 12:38Enconding of non-ASCII symbols is font-dependent. You should look for a font that supports Greek symbols. If you use one of the main fonts in IText, you won't have any trouble; if not, you should embed the font as described in the IText manual.
Ps: you should put your code, efforts and version used.
