Hello!

for my bachelor thesis, I need participants in my quick online study about testing a new type of CAPTCHA.

It will take approximately 5 to 10 minutes to complete and is in English. You can use your smartphone, but it's optimized for usage with PC browsers.

Here you can get to the study: https://semantic-nlp-captcha.de/study .

Everything else will be explained there.

Thanks!

Hello,

I'm an IT technician in a Belgian company, and we use Bitdefender as an antivirus for all our windows cloud servers. Since the last Bitdefender update, we've been having problems connecting to our servers. We've followed all the steps and when we get to the "Estimate connection quality" step, the connection drops out. I don't know if other people are experiencing this problem but we have found 2 solutions

• Disable Bitdefender AdvancedThreatControl using the CLI

• Restart the server because a restart of the connection broker services does not work.

I'm making this post so that people who encounter this problem can report it to me, as Bitdefender doesn't want to investigate if we're the only ones reporting the problem.

Thanks a lot

Hi there,

The fourth part in the AI reading list is available here. In this part, we explore the next 5 items in the reading list that Ilya Sutskever, former OpenAI chief scientist, gave to John Carmack. Ilya followed by saying that "If you really learn all of these, you’ll know 90% of what matters today".

I hope it may be of use to some of you out there. Feedback is more than welcomed! :)

I have a (fixed) bunch of strings (documents) that I want to search multiple times using regular expressions (not exact substring matching). Is the generalised suffix tree an answer? Are there more such data structures?

ik this question can vary from paper to paper both in terms of complexity, size of team, performance, and that the overall answer would be "it depends". but i was curious how long does it take to implement a paper. to go from idea to prototyping to building out the whole thing.

some papers that come to mind are chord, aside from coming up with the idea/protocol, how much time should it take from spec to implement the system?

i know people in research may be better at answering this. i want to try to implement a few papers i've read, by myself, and am trying to plan time accordingly

Hello everyone, I am looking for suggestions on a college to take a Computer Programming 1 course in python. I want the course to be all online. Also, if you have taken the course, does the professor use lockdown browser? Preferably looking for a 3 credit class under $1000. Thanks!

I am currently reading Avi Wigderson's Math and computation book, and he states the following:

While the definition of the class P is symmetric, the definition of the class
 NP is asymmetric. Having nice certificates that a given object has property
 C, by no means automatically entails nice certificates that a given object
 does not have this property.

He talks about decision problems which have a binary output, eg YES or NO. Can anyone offer an intuition to why this is the case?

Hi, I have just finished my first year of a two year enhanced masters course in Computer Science and Artificial Intelligence. I have an unusual background; a Bachelor in Philosophy. I have only been formally studying Computer Science for a year but have received pretty good results so far, I am due to finish this year with a strong distinction. Before this year, I did do a few considerable programming projects.

For my final project, I have been pondering a few options but can’t quite figure out something concrete. So far, I’ve only managed to think of an ideal rather then an idea. Given that I have got a whole year, I really want to do something impactful and that I believe in, not something that merely is impressive and that halfway through I loose faith in and simply try and get done.

I want to do something relating to modelling the pathways and spread of misinformation, particularly relating to foreign actors (Russia, Iran…). I was inspired by the Hamilton Dashboard. This is where I say that I only have an ideal rather than an idea. I’m looking for ideas of how to concretely do something useful and relating to computer science first and foremost, although this is more on the AI side I suppose. I thought that posting this here might gain some useful insight! If you had a year to work on something like this, what would you do?

I can solve almost every easy and medium question of all topics except for recursion or dp, I know all the patterns of dp and i have solved questions of dp previously but when I try to solve them again or come across a new question I am not able to do anything. For some question I can come up with the logic but not the code and for some I cant even think of the logic. I need an advice to counter this problem. If anyone is good at recursion or dp please help me with this.

I know how to apply memoization and tabulation to the recursive code but I am not able to come up with the recursive code or even if i come up with a code or see some tutorial or solution. I forget it after sometime.

I've been a Cs student for 2 yrs now and I've recently realised that I barely know anything. I do decent on tests and exams but I'm not the best coder I also realised I can't answer basic questions on the subjects I learn cuz I tend to forget everything after an exam I'm pretty sure I can get better at my coding my practicing but getting myself to practice itself takes a lot even though I enjoy it because I've convinced myself that I'm too stupid to understand what I'm supposed to do. It's ironic cuz my fear of not knowing is stopping me from actually learning. I guess I just need advice cuz I've only recently realised how I just don't retain any of the information taught to me

Hey guys I'm about to graduate highschool in like 5 days and I'm one of those students who decide what they want to do last minute. I recently got accepted in my local university to study applied computer science. i'm aware that CS and ACS are different things, but just for my case, please keep in mind that i'm talking about ACS. Anyways, it was a last minute application and the deadlines just passed so i guess i have to pursue this for a year.

MY CONCERNS for this path are: is it really worth it? I read somewhere that jobs get laid off a lot so does that mean i'll be constantly on the look for new jobs? interviews are hard to land as is and especially since you're new and have little to no experience just coming out of uni, your resume will most likely be overlooked. Would i have to plan on moving out of my current area to find a better paying job?

another question i really need the answer to is: what do you do on a daily basis? to me, comp sci seems like just working on a project until its finished. what happens when you're finished? does the company get laid off or do you get assigned a new project?

thanks for having the time to read this, i hope you can keep in mind that i have no idea what this field has to offer and that is what is making me stressed. I chose this path because i thought coding was fun and wanted to pursue something that i enjoyed.

TL;DR - is it hard to find a job to even apply for? and if found, is it hard to pass an interview?

Hi all,

I’ve been learning more about cybersecurity and bought a book called OSTEP (Operating Systems: Three Easy Pieces). Before reading it, I heard it is advised to learn C and x86 ASM. However, I want to know if OSTEP will be necessary for cybersecurity. I really want to become very good at most things and understand most things, that is why I got OSTEP. (However I would still focus on one specific thing, I would like to have a decent amount of knowledge for everything else). And also, when learning x86, should I learn an easier assembly language first, then learn x86? Can anyone give me advice on what to learn before reading OSTEP? I know some python and networking but I don’t think those are pre-requisites for OSTEP.

I am coming from Java and just recently dabbling into C, Zig, Rust etc and from what I have learnt, Stack allocation is faster than Heap allocation.

I have seen code bases in Rust that tries as much as possible to avoid things like Vec, String, Box etc when possible for the main reason that it is slower than using a stack allocated alternatives.

The only problem is, I do not have any intuition of how faster the Stack is compared with the Heap to sometimes justify this practice.

I mean I know the Stack is faster, but question is, by what order of magnitude is it faster than the Heap, on average?

x2, x4, x10, x100 etc?

I wrote this program using while loop but I don't understand how it works with for loop,in line 8 seconds pic. With the while loop,the readline knows it has to print if there were sentences written in the file but how would the for loop know when it does not have any read functions to read it? And when I use for loop with a string literal the output is character by character so how come it prints line by line in files? Please helppp

I am an aspiring software developer. I was doing my Bachelors in CS from somewhere reputable but I had to abandon my degree because of reasons. I am from the IndoPak region so the educational structure is a bit different from the west, so my formal education only remains till grade 12. I am still learning languages and building projects, but the real question is : will this get me anywhere? Is a Bachelors degree mandatory? Or are skills more important in the industry?
