    Any advice on understanding device drivers for windows and how to write my own?

    Posted: 13 Mar 2021 06:26 PM PST

    So far, I have found that a good understanding of C is a good place to start, what comes next? I want to be able to write a filter driver that displays disk speeds and then does something when it reaches a certain speed. Thank you!

    What will be the next “software engineering”?

    Posted: 13 Mar 2021 06:19 PM PST

    When I was in high school (2012) Many of my teachers would say to study software because their friends were getting paid 100k+.

    Now I've heard by many tech social media influencers that the days of getting a career for building website and applications for 100k are dying (as I've experienced it myself since I just graduated and average is about 80k in AZ).

    Obviously there's exceptions to that. But my question Is where are the 100k jobs? What tech sub field is getting these?

    I'm guessing machine learning, big data, data science, robotics, cloud etc

    How many have you actually got a good career from learning programming?

    Posted: 13 Mar 2021 06:49 AM PST

    To be honest i've met so many coders ( and many video game hackers and botters who created their own bot ) and stuff like that. So far i haven't heard none of them actually getting a career with their skills despite the fact i know a guy who studies everyday and is very good at it too.

    ​

    So far i only know few guys who actually made it. But both of them finished computer science in university ( one is studying there at the moment though ). But how many of you have got a job from self taught from courses?

    College vs day to day job workload

    Posted: 13 Mar 2021 11:47 AM PST

    Hi everyone, just have a short question for programmers that did CS in college or even bootcamps, would you say the workload of a day day job is higher than when you when taking CS classes(Data structure and algorithms for example)in college(assuming you were taking more than 10 credits at once)?

    greater than zero. If it is, we want to add the value to the account and return true. However

    the number of T-shirts being purchased; and size, which represents the size of the shirts being purchased.

    The prices for T-Shirts are as follows:

    smalls (represented by the character 's' or 'S'): $10 each

    medium (represented by the character 'm' or 'M'): $20 each

    larges (represented by the character 'l' or 'L'): $24 each

    Before allowing the purchase to go through, make sure it is a valid purchase first. Purchases can be invalid

    for a number of reasons. If the user does not have enough money, it is invalid. If the size character is invalid,

    the purchase is invalid. If they try to buy zero or a negative number of shirts, it is invalid.

    If a purchase is invalid, we will return false so that the error message can be shown by the main method. Otherwise

    we will subtract the cost from the user's balance and return true to signify that it is a valid purchase.

    Not sure what to use here

    Posted: 13 Mar 2021 06:38 PM PST

    I am working on trying to grab just the hyperlinks from a txt file for an assignment. I can get my code to grab just the hyperlink, but it still shows all the white space and gives me the incorrect amount of lines I need. I've been trying a couple of different things but I am not sure where to go from here. Any help would be greatly appreciated. Here is my code so far:

    file = open('mbox-short.txt') count = 0 for line in file: if line.find("http"): location1 = line.find("http") location2 = line.find(" ",location1) line = line.replace(")","") count = count + 1 print(line[location1:location2]) print(count)

    and here is the output up until the first text comes in:

    http://source.sakaiproject.org/viewsvn/?view=rev&rev=39772

    Edit: The code box won't show it, but there are about 25 blank lines before this shows up.

    Help using DivMod or bit shifting in Python to decode hex values to ASCII

    Posted: 13 Mar 2021 06:07 PM PST

    I am trying to write a function that takes a list of Hex values that looks like this " [0x4974, 0x2077,0x6173,0x2074,0x6865,0x2062, 0x6573,0x7420,0x6f66,0x2074,

    0x696D, 0x6573,0x2c20,0x6974,0x2077,0x6173,0x2074,0x6865,0x2077,0x6f72,0x7374,0x206f,

    0x6620,0x7469,0x6d65,0x732e] " And decodes it to ASCII then prints back the message in ASCII. The hard part (for me) is my teacher gave specific diameters for how we must write the function. 1.) we must use a for loop 2.) Conversions can only be done using the divmod function or bit shifting. I have created a program that works already but it does not use divmod or bit shifting to decode, it uses built in libraries. If anyone has any examples using divmod or bit shifting that would be super helpful. Even if its just a link to a resource online i havent been able to find any examples, or at least the ones i find on divmod dont make sense to me. Any help is appreciated Thanks!

    Online interface for DnD World

    Posted: 13 Mar 2021 04:50 PM PST

    Without sounding stupid as I can be a slow learner at times:

    I want to create an online interface where players can hover over different icons and be given a text box, with links if they click them.
    I know this is easy enough to do in all likelihood I was just wondering if someone could point me the right way on what this would be called or where I could learn it?

    What is the extent of modding capabilities in among us?

    Posted: 13 Mar 2021 04:20 PM PST

    I'm not sure this is the right place to ask, but I don't think the right people will see this in r/amongus

    About half a year ago I assumed modding was nigh impossible in among us. However, we have ottomated (a non affiliated mod creator) make some role and gameplay mods which are amazing to say the least.

    A bit of context about the game, I'm thinking the only reason why among us mods can go so in depth is because so much of the game is handled on the client. It coincides with their hacker problem but that's an entirely different issue.

    Anyways, if among us can handle mods like this, then ...

    • What can or can't be modded? Just to list some examples, can we add more alignments, new game mechanics, new tasks, new victory conditions, a new UI, and new maps?
    • Why aren't more people doing this? Among us has (or had) a pretty large playerbase so I imagine "know how" isn't a large contributing factor. Plus it's a coding project that's been very unexplored, with a large audience

    _M_construct null not valid core dumped? Data Structures problem

    Posted: 13 Mar 2021 02:20 PM PST

    Hey guys, so I have a question. So I'm trying to implement the Bag ADT in C++ using a linked data structure with an array of cells. I've edited the ArrayLinkedBag.cpp and the header file however I keep running into this weird error where the whole thing aborts whenever I try to make test and I was wondering if anyone can help me figure out where I went wrong. I've tried everything to pinpoint the error including rewriting everything and testing the lines one by one but it just isn't working. Any help would be appreciated. I've attached my code for the two files as well as the error message I keep getting.

    ArrayLinkedBag.cpp

    /** Implementation file for the class ArrayLinkedBag. @file ArrayLinkedBag.cpp */ #include "ArrayLinkedBag.h" #include <cstddef> template<class ItemType> ArrayLinkedBag<ItemType>::ArrayLinkedBag(): head(-1), free(0), itemCount(0) { //create free list for (int i = 0; i < DEFAULT_CAPACITY; i++) { cells[i] = (Cell<ItemType>){"a",i+1}; } } // end default constructor template<class ItemType> int ArrayLinkedBag<ItemType>::getCurrentSize() const { return itemCount; } // end getCurrentSize template<class ItemType> bool ArrayLinkedBag<ItemType>::isEmpty() const { return itemCount == 0; } // end isEmpty template<class ItemType> bool ArrayLinkedBag<ItemType>::add(const ItemType& newEntry) { bool hasRoomToAdd = (itemCount < DEFAULT_CAPACITY); if (hasRoomToAdd) { int newFree=cells[free].next; cells[free]=(Cell<ItemType>){newEntry,head}; head=free; itemCount++; free=newFree; } // end if return hasRoomToAdd; } // end add template<class ItemType> bool ArrayLinkedBag<ItemType>::remove(const ItemType& anEntry) { int locatedIndex = getIndexOf(anEntry); bool canRemoveItem = !isEmpty() && (locatedIndex > -1); if (canRemoveItem) { itemCount--; cells[locatedIndex] = (Cell<ItemType>){NULL, free}; free=locatedIndex; } // end if return canRemoveItem; } // end remove template<class ItemType> void ArrayLinkedBag<ItemType>::clear() { //reset free list for (int i = 0; i < DEFAULT_CAPACITY; i++) { cells[i] = (Cell<ItemType>){"a",i+1}; } head=-1; free=0; itemCount = 0; } // end clear template<class ItemType> bool ArrayLinkedBag<ItemType>::contains(const ItemType& anEntry) const { return getIndexOf(anEntry) > -1; } // end contains template<class ItemType> int ArrayLinkedBag<ItemType>::getFrequencyOf(const ItemType& anEntry) const { int frequency = 0; int curIndex = 0; // Current array index while (curIndex < itemCount) { if (cells[curIndex].item == anEntry) { frequency++; } // end if curIndex++; // Increment to next entry } // end while return frequency; } // end getFrequencyOf template<class ItemType> std::vector<ItemType> ArrayLinkedBag<ItemType>::toVector() const { std::vector<ItemType> bagContents; for (int i = 0; i < itemCount; i++) bagContents.push_back(cells[i].item); return bagContents; } // end toVector // private template<class ItemType> int ArrayLinkedBag<ItemType>::getIndexOf(const ItemType& target) const { bool found = false; int result = -1; int searchIndex = 0; // If the bag is empty, itemCount is zero, so loop is skipped while (!found && (searchIndex < itemCount)) { if (cells[searchIndex].item == target) { found = true; result = searchIndex; } else { searchIndex++; } // end if } // end while return result; } // end getIndexOf
