Junior year Comp Sci switch - How do I Catch Up?

10 min 33 sec ago

I was going to tech and transferred into computer science at my state's University after my sophomore year.

I'm currently a first semester senior and I've been accepted into my Uni's accelerated masters program. I'm in my first data structures and algorithms class and it's a bit disheartening when a lot of my peers seem so knowledgeable compared to me...

I strive to do a software engineering internship at a large company this coming summer but I feel like I my programming skills are lacking and I don't have any full-stack projects under my belt.

With so much knowledge out there it's very overwhelming finding a place to start. I just really want to improve my skills as a programmer, get a good project to put on my GitHub+Resume & earn a summer software engineering internship at a nice company

Oh, and not feel like a failure - Kind people of Reddit I call upon you!

Computer science vs electrical engineering help

Thu, 09/20/2018 - 20:34

I am due to start a mechanical and electrical engineering course at uni in the next few days, however these past few months I have been thinking about a switch to computer science. This would mean taking a gap year as the uni wont allow a transfer, so I have till the end of tonight I guess to decide what I'm going to do as the move in day is saturday.

Basically, the more I have looked into the subjects , the more I have been put off of mechanical engineering, so if I were to start I would change to just electrical engineering. The thing I am put off by is the practical work and the practical work I would have to do when I get a job. Throughout school I have hated any practicals in physics, which includes working with oscilloscopes , ammeters voltmeters etc as it just involved testing circuits and writing long lists of results from the circuits, which I find quite tedious and boring. I also found the reports we had to write on these practicals about the accuracy and precision of equipment etc etc, also very boring. When choosing the degree initially I didn't keep that in mind and chose it just because I like maths and physics (less so with generators and electromagnetism as I find the concepts harder to grasp). Taking all of this into consideration, I am leaning towards a computer science degree.

My main reason for choosing engineering was the problem solving aspect of it and computer science is all problem solving, I have been trying some online courses in programming in python and watching some computer science lectures and have been finding them quite interesting. While the programming side I am interested in, the algorithms, data structures etc, I don't have much knowledge about and at this point am not 100% sure if the course would suit me as I have had no experience with the other topics. I was hoping someone could give some insight into the other topics in computer science and help me get out of this rut as I don't want to take a gap year just to find out that I don't suit computer science

Math in CS vs Math in CompEng

Thu, 09/20/2018 - 18:00

Both majors take different math classes. I heard CompEng has more math but Ive also heard some CS students say CS is a branch of math?? So which one is right then? Which has more math?

Computer Engineering vs CS and Math double major?

Thu, 09/20/2018 - 17:44

So Im in comp eng rn. I have come to the realization I will probably work in software in the future, so I wanted to ask what knowledge would be more useful? A bit of EE or a bit of Math? I know the differences of each field but I cant decide, everything seems interesting which is why Im in comp eng. So instead which of these 2 would be more useful to know as a whole in this field?

Learning CS vs Gettin better grade in a class

Thu, 09/20/2018 - 17:22

Hi all. I'm an international student who take Computer Science class(mostly focusing on algorithm analysis and design patter with Java) in a university in America. Almost every week, my professor give assignments(PDF files which describes like you have to create methods and classes following a description).

I always somehow figure out a solution to those assignments and get a satisfactory grade on Canvas. My point is that I almost learn nothing from a professor or given materials. I'm not confident with my coding and knowledge about CS. Although my professor is nice and try hard to teach us as understandable as possible, they(instructions, or materials) sound surface and not practical.

Easy to read(due to my bad writing)

  1. The lecture doesn't give me sufficient knowledge of CS
  2. I want to study it deeply, but I'm not sure I have enough amount of time to learn.

If any of you have an insight or an idea, please put a comment! Thanks!

Relationship between Integral (Calculus) and Information Technology

Thu, 09/20/2018 - 17:12

Does anyone know the relationship between integral (in Calculus) and Information Technology (or Computer Science) in general? For example the application, the use of integral in IT...

I'm sorry if this sounds complicated but I'm asking for my friend and he's struggling so much at this question. Thank you in advance!

Selected a wrong project for Thesis and now I am in trouble

Thu, 09/20/2018 - 14:31

I am doing my post graduation and for the final year we need to do a Thesis report. So basically we needed to create a project which looks heavy on the day of final presentation. So I decided with some project and now I am finding out that project is mostly about NLP and Deep neural networks. Both of these topics are out of scope for me. I need to prepare a PPT on the topic and present it after two days. So I need a title which suits my requirement. I am comfortable with PHP,HTML,SQL and C++. Now I know that there are not heavy projects based on these but if you have anything in mind which is a good topic please let me know.

Is there any way to check the similiarity of two sentences?

Thu, 09/20/2018 - 14:14

For example :

S1 : Trump will support China.

S2: China will get help from Trump.

S3: China will not get any help from Trump.

S4: China will get support from USA.

So is there any ready to use tool to find if some sentences are similiar. For example, S1 S2 S3 are similiar but S1 and S3 are not. I read about Google Sentence Encoder but not sure if that will work here.

How would you approach the problem of fake news detection in real time?

Thu, 09/20/2018 - 09:23

So I am working on Fake News detection. I am planning to detect only political fake news and nothing else. So if some news article says that if 'Trump has passed away' then I need to tell it's fake. I don't want to go towards classification algorithms. Rather than using classification algorithms I would like to use analytical approach to detect the fake news. This is what I have come up with so far -

So I will create a list of trusted websites, let's say BBC is in that list. Once user inputs the headline and the content of the article, I will scrap all the related articles to given headline from trusted websites and then compare those articles with current article. Now the first problem I am facing is that is there any way to compare two articles. I mean both articles might say same thing but in different way. How do you do that? Is there any NLP based algorithm which can tell if two articles are same.

Apart from that do you have any other ideas of detecting the fake news? Any approach is appreciated.

Are there Computer Science Podcasts with coding best practices

Thu, 09/20/2018 - 08:51


as stated in the title: are there any podcasts concerning computer science, but not with news and gossip but rather coding best practices, lessons learned and problem solving?

I don't want another talk show, I want something beneficial I can use in my everyday coding

New subreddit: r/DigitalPhilosophy

Thu, 09/20/2018 - 03:42

Digital philosophy is a direction in philosophy/metaphysics that relies on computer science and theory of computation. It commonly assumes discrete and finite/countable ontology.

Posts about digital philosophy together with posts close in spirit are welcome in this subreddit. For example posts about philosophy of artificial intelligence, artificial life/open-ended evolution are also welcome.

Original definition of the digital philosophy (DP) by Edward Fredkin was rather specific but for example Gregory Chaitin's ideas are indeterministic instead of deterministic but they are still considered belonging to DP. So it's more an umbrella term now.

According to Wikipedia DP is advocated by certain mathematicians and theoretical physicists, including: Edward Fredkin, Konrad Zuse, Stephen Wolfram, Rudy Rucker, Gregory Chaitin, and Seth Lloyd.

Comp Sci Club Help

Wed, 09/19/2018 - 20:46

I just realized that my school had missed one of the largest components of a club last year: a well-knit community.

For the very first meeting, I was considering having a comp-sci related bonding activity between club members for a start, but am struggling to come up with any; Any suggestions are greatly appreciated, thank you!
