I'm told to write a program in 'C' to print the contents of the 'super block'. Can anybody tell me how to read the contents of the super block. Which system call can be used to do so?
Thanks.
I guess what they want you to do is precisely to find this.
Hint: Googling "superblock linux" and pressing "I'm feeling lucky" got me straight to the first links to the answers. (Yes, there are several :) )!
Hint hint: If the fs is extN, there is a catch!

I don't know if it is possible, but I have a Jupyter notebook where I'd like to disable some cells in case of a whole run.
That is, 'Run All' would jump over these cells and not trigger them, but they could still be used if ran alone (e.g. with Ctrl+Enter) without changing the code.
I know %%script false --no-raise-error does the trick, but you need to manually change a constant to re-enable the cells when you need them. Ideally, I'd not have to change anything in the code.
Thanks in advance!
Your question resembles another question on here that I've answered recently. It's not the same question but I think my solution to that one actually works better for you. Here's the link to it and I hope it helps: https://stackoverflow.com/a/73978254/16264178
(PS I previously just copy-pasted my answer to the other question to here and that got flagged by a moderator. He was right that that wasn't best practice (answering different questions with the same answer verbatim). The recommendation though was to flag this thread as a duplicate of the other, which it isn't really. They're similar questions but my suggestion was a fairly imperfect solution to the other query, whereas I think it applies very well to the question in this thread. That's why I reposted my answer here with a link to the other one. That was the best thing I could see to do but people should feel free to enlighten me if they know better)
Anyone know how to set Notepad++ as default text editor for SAS, Stata and R?
I'm having the hardest time finding anything online (particularly for SAS). Looking for ability to run code from Notepad++ as well as setup color coding.
Thanks.
Why not just go the GUI route: right click, e.g., any foo.R file and select "Open with...", then pick Np++ and click the "always open this file type.." button. Rinse, lather, repeat.
BTW, for R, if you don't already have it, get "NppToR" , a little app which lets you execute code directly from the Npp window.
On windows you can either:
manually edit the keys for the file type to set the value of HKEY_CLASSES_ROOT\FILE_TYPE\shell\edit\command where FILE_TYPE is the appropriate one for each of the files extensions you wish to change this is quite hard work or
you can use a program that does it for you such as the free Default Programs Editor
In either case the first thing to do is to back up the registry.
I would seriously suggest looking into using one of the many, some free IDEs as they will automatically include the run from edit environment, syntax highlighting, code completion and, in many cases, debugging as well.
Notepad++ is my favorite editor and I was in the same shoes as you are now.
I am assuming that you are in Windows (Notepad ++ doesn't exist in Mac, saddest thing for me)
Please follow the steps mentioned in the below webpage and do as the author says.

Now for in-line editing , it may be not be the best choice for SAS. Although I haven't tried it much so not a good person to comment on it.
I want to use the semanticvectors API. I am completely new at this. I want to make a program which takes some documents and searches keywords and returns the documents which are conceptually similar to the search keywords. I want to know if there is any document from which I can get all the function and their functionality description and from which I can learn or if there is any example to do so.
I have checked
https://code.google.com/p/semanticvectors/
and
http://semanticvectors.googlecode.com/svn/javadoc/latest-stable/index.html
but couldn't understand anything. Please help me. Thank you.
It is not clear what you want to do with SemanticVectors. Here is where you should start off with:

And for specific questions, it would be fruitful if you ask on project's forum itself:

I run a proxy for the Pirate Bay. I don't think I'm allowed to link to the script itself but it called "unblocked pirate bay".
And this script doesn't have normal code like I know it. It encrypts (?) everything and I'm a little suspicious of it. It looks kind of like this (but with no spaces).
eval(
gzinflate(
str_rot13(
base64_decode('')
)
)
);
And inside the base64_decode is a LONG list of random strings (~8000 characters). Is there a quick and easy way to decode this? So I can see whats going on?
Yes. The answer is right there in your question. Take the scary string, base64 decode it, ROT13 it, and then GZ inflate it. When you do that you'll have executable JavaScript code. I suspect it'll be highly obfuscated and not very readable, but it will at least be valid JavaScript.
Please take a look at this:
It says 'Found 6 results in 3 files', but how can I see which files are those and the exact line, you know the usual way.
I've haven't set any options or settings anywhere, its just all default settings.
This is making me crazy!
Thanks everyone for taking interest in it, but I think I found the answer. Its as dumb as the question.
There is another field to filter the result at bottom and when I cleaned it I got everything back to normal :)
Hope this saves somebody hours.
