QUESTION
A simple x86_64 shellcode is written:
...ANSWER
Answered 2020-Nov-30 at 20:34Two issues.
First, you're using the n
GDB command, which is supposed to step to the next source line, which may be many instructions away. (And when you're executing code that's not part of the binary, line numbers don't make sense anyway and n
will not work reliably.) You want to be using ni
instead, or better yet si
which will always execute exactly one instruction without trying to step over subroutine calls and the like.
Indeed, note the value of RIP
in the register dump after the segfault. It's not the address of your push rbx
, so that's not the instruction that faulted; rather, it's the following instruction, which you had meant to be mov rcx, rsp
.
How can a simple register move cause a segfault? Because it's not a register move anymore - you just overwrote it. Compare the values of RSP and RIP. You're executing code from the stack, and your push rbx
stored to address 0x00007FFFFFFFEA78
, while the mov rcx, rsp
is a three-byte instruction starting at 0x7fffffffea76
. So you just overwrote its third byte. If you do another disassemble
or x/i $rip
at this point, you'll see the instruction you ended up executing instead - I bet it accesses memory.
Indeed, mov rcx, rsp
is encoded as 48 89 e1
. The low byte of rbx
is 0x88
, and overwriting the third byte with 88
produces 48 89 88 xx xx xx xx
which is mov [rax+disp], rcx
.
QUESTION
I have been stucked on this for a couple of days, all help would be really cherished.
I have a list and detail view which are function based views, my detail view works perfectly because i am able to pass the "/str:pk/" at the end of the url and also with the request as(def po_detail(request, pk)) which in turn i am able to pass into my view functions and they all successfully return the unique id i desire.
I have a custom queryset i have written to help me get the sum total amount of some payments and return it in both the list and detail view.
The issues now is that i am not able to get each unique items in my list view page because i am not able to pass the pk into the url and the request function as the object i used it for in detail function has access to the pk.
I have id=True so as to prevent error, because when i made id=id, it gave me a error saying, "Field 'id' expected a number but got ."
This is the image of the detail template which works well as well as for other id
I would love if any one can provide an hint, suggestion, or solution.
Thanks, Oyero H.O

Answered 2020-Sep-19 at 06:50First, fix your error
po_detail = PurchaseOrder.objects.get(id=True) payment_lists_doc =
PurchaseOrderPayment.objects.filter(po_number__id=True) amount = po_detail.po_amount = True
You need to pass an id (integer) to these fields

QUESTION
I have a large dataframe consisting of tweets, and keyword dictionaries loaded as values that have words associated with morality (kw_Moral
) and emotion (kw_Emo
). In the past I have used the keyword dictionaries to subset a dataframe to get only the tweets that have one or more of the keywords present.
For example, to create a subset with only those tweets that have emotional keywords, I loaded in my keyword dictionary...

Answered 2018-Dec-12 at 14:02Your requirement would seem to lend itself to a matrix type output, where, for example, the tweets are rows, and each term is a column, with the cell value being the number of occurrences. Here is a base R solution using gsub

QUESTION
I have a global variable that needs to be altered by user input generated by a function.
I'm trying to make a Zork style text game and want the character name, input
by the user during a character creation function
, to alter a global variable.
I've been able to create a class
to store character information and been able to display most of the information in the class
on a mock command prompt I have appear when input
options are available to the user.
I use a global variable
to define the character's name until the character creation stage. I use the 'global
' keyword in the creation()
function
to alter the 'name' variable
with user input
.
When the prompt is ready to be used it still only displays the name as 00
instead of the input
generated during the creation()
function
I am exceedingly novice. Any advice, tips or direction would be cherished.
...ANSWER
Answered 2019-May-25 at 03:29Ahhh, took a little bit, but I think I found the problem.
You initialize Player 1 using the name variable before calling Creation()
, where you change the global name variable, so Player1 is created with the original name “00.”
Move the line:
Player1 = Character(name, 100, 100, 1, 0)
Put it after Creation()
at the bottom but before segway()
Python more or less executes any unindented code (code that isn’t in a function, class, etc.) from top to bottom.
So, moving from top to bottom in your program, it sets name to “00”, then creates Player1 with the original name, then calls Intro()
, Creation()
(which changes the name to t00n), and finally segway()
.
QUESTION
I have about 300 small- or medium-sized Node apps that my team has produced over the past few years which I'm trying to clean up and organize. Suffice it to say that my cherished assistants have not always meticulously used the --save
flag with npm install
, so the package.json
files often do not reflect all the dependencies. Other times, they include packages that are not actually used because someone DID use --save
and then changed his mind about needing that packages.
The apps all use the same filename conventions, so we can at least be thankful for that.
I could write a script that read the source code as a text file, used regex to look for require
and import
, and got the package names. I can deal with versioning myself. But this seems inelegant and inefficient.
I've noticed when I run webpack
on a project that the compiler processes the code, detecting any illegal syntax and, more to the point, any import of a package that is not available because it wasn't installed.
Normally I'd chafe at the process of executing an unknown script, but since these are all scripts written by known entities, I'm not worried about malfeasance. I'm mainly unclear how it is that a program like webpack
parses a .js
file without necessarily executing it, and returns specific errors with line numbers.
I don't even necessarily need to automate the process of adding missing dependencies to the package.json
file--many of the 300 apps are properly built. But it would still save me eons to quickly detect what's missing.
Does running a script to see if it works involve a VM? Or is it as simple as running the script from another script? Naturally, the apps themselves aren't packages, so just trying to require
them wouldn't seem to work. Maybe it uses JSLint?
ANSWER
Answered 2019-Apr-15 at 04:04Webpack does not run any scripts that run your code to make sure it is working. It uses Babel, which is a transpiler (which also does not run your code).
The way compilers work is they scan through your code and make sure that everything is syntactically correct, such as matching parentheses or braces, whether a variable you use has been declared, and in statically typed languages, whether your types are correct. While/after they do this, they spit out code that the target system can use. In the case of C, a compiler takes your C code and turns it into machine code or assembly, depending on the options you specify.
The difference between a compiler and transpiler, generally, is that compilers translate the code downwards (towards the machine level) and transpilers translate the code horizontally. Think Typescript -> Javascript, or in this case, ES6+ Javascript -> ES[compatible] Javascript. This means that in order for Babel to convert your ES6 code to something more compatible, it has to read through all of your files and perform basic integrity checks. Specifically, if it sees you importing code, it's going to try and access the module/files because that's what the instruction is. If it can't, then it'll throw an error.
This is also why you'll see compilation errors but not runtime errors, similar to other languages. If Babel were to actually run your code to check for errors, it could also find runtime errors. However, code has many branches of execution, so to find these and then also set the conditions to make them execute is a titanic task. This is why we have testing tools.
To more directly address your questions/concerns:Does running a script to see if it works involve a VM?
Nope
Or is it as simple as running the script from another script?
Nope
I'm mainly unclear how it is that a program like webpack parses a .js file without necessarily executing it, and returns specific errors with line numbers.

But this seems inelegant and inefficient.
unfortunately, this is essentially what Babel does.
NoteI double checked the Webpack docs, and see that they do have their own transpiler, but it only handles import/export statements, and recommend using another transpiler like Babel or Bublé to transpile the rest, which is what I mean when I refer to how Webpack uses Babel.

QUESTION
I grasp that this code isn't working because the request is somehow insufficient, but I'm uncertain as to how to go about correcting it. I'm trying to configure it so that, if the ajax data matches the username, it will redirect to home.html. Any help would be so greatly cherished! (PS: the print calls are working - if the user exists, it prints the "else" statement and vice versa. Nevertheless, the redirect still doesn't work!)
views.py
...ANSWER
Answered 2019-Feb-19 at 18:21Simply put a return statement in front of your call to redirect, it returns an HttpResponse Object and that needs returned to the caller.
EDIT: OP updated and added return, however this should be a good fix. Please try to pass URL and Boolean indicating whether you should redirect or not. Django AJAX Redirect
