I have a filterSection object array and a customFilter array and I'm trying to loop through both and remove any matching elements from the filterSection array.
The problem I'm running into is that I can only seem to remove the first match and nothing beyond that and I'm not sure what I'm doing wrong.
This is my function for compare/remove:
...ANSWER
Answered 2021-Apr-01 at 03:19Two problems, you are returning on the first match, and you are mutating the original filterSelection
array in the loop so the length changes and you don't iterate over the entire array. You should store it to a temporary array to avoid this problem. Something like this:
QUESTION
I am going through some CTF challenges at https://recruit.osiris.cyber.nyu.edu/challenges.
I got to one for Template Programming where the task is to "Read /flag.txt from the server. http://recruit.osiris.cyber.nyu.edu:2000"
I am not asking for a solution, but I would like some better understanding of what is going on below:
- What is this code doing?
- Should I be worried about running out of Debugging mode and/or using host="0.0.0.0"?
- What are some resources that could help me understand this? I tried reading through the Flask documentation and the tutorialspoint page, but I am unclear as to how this doesn't just set up a local server for testing as opposed to accessing a remote server...
- If I ctrl+C do I need to worry about leaving a server still running on an open port when I am not in Debugging mode?
ANSWER
Answered 2020-Jun-25 at 23:01I think I can answer most of these.
As you probably already figured out, Flask is a fairly basic web framework. By the look of things, what you have there is a copy of the code running at the CTF site. It displays just two pages; one that contains the initial web form (
templates/index.html
) and another that uses a query string variable to greet the user (templates/hello.html
) when a name has been provided.You don't really have to run this code yourself. The
0.0.0.0
host address is catch-all that matches all IPv4 addresses on the local machine, which would include local addresses like192.168.0.1
and127.0.0.1
as well as the IP address used for incoming connections to the server.Like I said, this is the code running on the remote server.
I think what you need to do is find some way of crafting a request to this web service in such a way that it reveals the contents of
/flag.txt
instead of (or perhaps in addition to) just saying hello. A quick search for something like "flask include file vulnerability" should give you some idea of how to attack this problem.
QUESTION
I'm having a problem making a unitary test with jest over an es6 class. I don't know if the configurations were made properly or if I need some extra package.
This is my file queue.js
...ANSWER
Answered 2020-Apr-25 at 10:49The error you are getting means that one of your presets isn't compatible with the babel version.
Looking at your package.json
you are using babel version 6. But both jest
and babel-jest
use later versions of babel. This causes your es2015 preset not to work correctly.
If you are tied to your current version of babel you can downgrade your jest and babel-jest dependencies to a version that uses older versions of babel:

I'm trying to create a Java code that creates a nifi customized processor ! so in order to do that I need to use windows cmd windows and launch mvn archetype:generate
then choose the modele nifi by typing nifi
then choose the project by typing1
the I need to write the groupeId, the artifact ...
I need to do all that automatically by using a java code : I tryed this code :
...ANSWER
Answered 2020-Apr-12 at 20:55Just don't do that. The mvn command could accept all required arguments in command line so there are no interactive actions required. See the documentation on the plugin and supply parameters accordingly into single command. See http://maven.apache.org/archetype/maven-archetype-plugin/generate-mojo.html There is an example here: Specify archetype for archetype:generate on command line

QUESTION
I'm just learning Electron, and I'm trying to open a file and display it in a new window. I click a button in the initial (root) window, which then opens an "open file" dialog, from which I can get a file path. I would like to then open that file, create a window, and pass the contents of the file to the new window. My issue is in getting the string with the file contents into the callback function for when the window is ready; i that even possible? My main.js code:
...ANSWER
Answered 2020-Feb-23 at 01:04I'm not sure I fully understand what you need to do but you can use the ready-to-show event to send data to a new window before the window is shown for the first time.
This probably makes the most sense if the data is being used to populate existing page elements – though I guess there is no reason you can't blow out whatever was on the page with the new data – it's just another render.
While loading the page, the ready-to-show event will be emitted when the renderer process has rendered the page for the first time if the window has not been shown yet.

QUESTION
I have a .csv file (generated from exporting a googleDoc spreadsheet) that I need to extract information from. The information does NOT contain a consistent delimiter.
I am currently using a comma (,) as a delimiter, which works fine when getting information from the first 4 columns.
However, when I want to extract information from column 8, I get incorrect data. This is because some cells contain 2 pieces of information split up by commas.
Cells with 2 pieces of information are given doublequotes (") at the start and end. Providing data like 1,"2,3",4
My splitter cannot recognise the difference between 1,2,3,4 and 1,"2,3",4 so the third value returns 3
for the first set and 3"
for the second set, when it should return 4
for the second set (3 for the first set is expected)
Below is an extract of the .csv file I'm using.
...ANSWER
Answered 2019-Nov-29 at 21:02First off, PowerShell has the built in ability to parse and manipulate CSV documents, so that would be a better option. But I will stick with batch processing.
Regular Expression solutionRegular expressions are no good to a pure native batch solution for two reasons:
- It is impossible to alter FOR /F behavior to parse tokens by regular expressions - it is what it is - very limited.
- To parse your file with FOR /F you would need to manipulate each line prior to parsing. Batch does not have any regex utility that can alter content. It only has FINDSTR which can do very crude regex searches, but it always returns the original matching line. On top of that, the FINDSTR regex is so crippled, I'm not sure you could properly parse a CSV anyway.
You could use custom JScript or VBScript via CSCRIPT to preprocess the file with a regular expression search and replace in such a way that FOR /F could then parse the file. I have already written a hybrid JScript/batch regular expression processing utility called JREPL.BAT that works well for this.
A quoted CSV field can contain quote literals, in which case the quote liberals are doubled. The following regex would match any CSV token (not including the comma delimiter) ("(?:""|[^"])*"|[^,"]*)
. It looks for a quote followed by any number of non-quote characters and/or doubled quotes, followed by a closing quote or any number of characters not including quote or comma. But your CSV does not contain any doubled quote literals, so the regex can be simplified to ("[^"]*"|[^,"]*)
.
CSCRIPT has no mechanism to pass quote literals within arguments, so JREPL has an /XSEQ option to enable extended escape sequence support, including \q
to represent "
. The other option is to use the standard \x22
sequence. JREPL "(\q[^\q]*\q|[^,\q]*)," "$1;" /XSEQ /F "test.csv"
will match any token (possibly empty) followed by a comma delimiter, and preserve the token and replace the comma with a semicolon.
But that still leaves empty tokens, and FOR /F does not properly parse empty tokens. So I can throw a bit of JSCRIPT into the replacement term to remove any existing quotes, and then surround each token with quotes (except for the last one, where it isn't needed)
JREPL "(\q[^\q]*\q|[^,\q]*)," "$txt='\q'+$1.replace(/'\q'/,'')+'\q;'" /JQ /XSEQ /F "test.csv"
Here is a demonstration showing how it could be used to parse your CSV:

I've been trying to parse a dictionary, which is returned by a database I'm working on, but I'm not sure about the best approach to take. I think the difficulty is being caused by the fact that the list sizes within the dictionary are not symmetrical, so my approach doesn't seem to be able to pull out what I'm looking for.
