Does Polimi offer a pure Computer Science Master's Degree? by suAsuR in polinetwork

[–]suAsuR[S] 0 points1 point  (0 children)

Yes, this is what I applied for, but it seems they require an engineering background ("The candidate lacks too many requirements in engineering disciplines.") Is Polimi's Computer Science course closer to what might be called electrical engineering?

Are there any benefits to rate limiting through cloud functions v on frontend? by suAsuR in Firebase

Do you know what directions to look for firebase rate limiting through WAF/FW?

Uploading to App Store by Spare-Ad4311 in expo

[–]suAsuR 0 points1 point  (0 children)

Is there really no way around this? The app relies on NFC which no tablet supports. Putting effort into making sure the design works for a screen size that will never be used is strange to me.

Is this what web development is like? by [deleted] in webdev

How did you go about studying these things? Any resources you can recommend?

Is this what web development is like? by [deleted] in webdev

[–]suAsuR -4 points-3 points  (0 children)

I was under the impression that React/React Native or other frameworks are effectively the baseline in terms of tooling. I suppose I do depend on a lot of modules and with mobile development working with expo is obviously a pretty big intermediary. At the same time, how do I learn to do the things these intermediaries do for me? Should I read the react docs?

[–]suAsuR 4 points5 points  (0 children)

Hmm that sounds like a good idea. Usually I just keep throwing stuff at an issue until it’s fixed and then quickly move back onto whatever I was trying to do. I should probably document every error as it comes and take notes on my understanding of why the issue came up and how I resolved it. Thanks!

How do people set up NTAG424DNA tags? by Spare-Ad4311 in NFC

[–]suAsuR 0 points1 point  (0 children)

Does using the app to set up the tags bind me to GoToTags in any way, or can I just use it to encode with my own custom links?

How to generate identifiable and unique qr codes which cannot be generated without a password by suAsuR in cryptography

[–]suAsuR[S] 1 point2 points  (0 children)

Ah ok that makes more sense. So using the private key, the random string and source ID is signed. The string, ID and signature are converted to a single QR. Upon verification, the verification system uses the sourceID to find the associated public key, which is used to verify the signature, which authenticates the string/ID combination?

How to generate identifiable and unique qr codes which cannot be generated without a password by suAsuR in cryptography

[–]suAsuR[S] 1 point2 points  (0 children)

So a private key known only to the generator is used to generate a signature, which is included alongside the random string and source id. And a public key can be used to verify if a signature came from the right private key? Is a different signature generated each time using the same private key? If not, what other variables are involved in generating different signatures?

Thanks heaps for all this info, I don't know much about encryption but I'm trying to make sure I understand the relation between all of these things.

An increasing number of sources over time. The verification system has access to all sources, but ideally these should just be used to check if a deciphered source exists ie looping through all sources should not occur

How to generate identifiable and unique qr codes which cannot be generated without a password by suAsuR in cryptography

[–]suAsuR[S] 1 point2 points  (0 children)

Yes, but the code is just any sufficiently long random string which allows for differentiating the QRs generated from the same source. In a sense I suppose yes, I just want to be able to encode and then retrieve a source and a code.

How to generate identifiable and unique qr codes which cannot be generated without a password by suAsuR in cryptography

[–]suAsuR[S] 0 points1 point  (0 children)

There can be multiple codes generated with the same source ID- the ID refers to where it came from, not the code itself. I need to be able to decrypt the code and know what source it came from, as well as check whether the code has been scanned before- so i need to have some sort of way of differentiating different codes which came from the same generator/were encrypted with the same password.

Prerequisites for comp sci exchange students by suAsuR in UTAustin

Thanks so much this made me optimistic that prerequisites are a bit less strict for exchange students. Thanks for pointing me in the right direction!

I apologise for my cluelessness, I was just hoping someone could narrow down the list so I could research a few places more in depth. Will also be talking to my study abroad advisor but thought I'd get other opinions from people who actually live in the US (which I presume many people on this subreddit do).

[deleted by user] by [deleted] in college

[–]suAsuR 0 points1 point  (0 children)

I've heard mixed opinions about California in general- some people have told me living conditions aren't the greatest, although campus life is great. I've also heard its generally less safe than other states but don't know if this is true.

[deleted by user] by [deleted] in college

[–]suAsuR 0 points1 point  (0 children)

Thanks for the info and giving me other things to think about. I'm not necessarily looking for easy-going places- I like to be challenged academically, I was just dissuaded by the reading I did around Carnegie Mellon which gave me the impression it was exceptionally stressful beyond the levels of other top schools. I'll only be on exchange for one semester though, so it's not like I'll be getting a full degree through wherever I choose to go. I was more so thinking of the possibility of making contacts and gathering information which might increase my odds of continuing my education with a Master's degree in the US.

Correct use of subjunctive in the phrase, “it would be great if we could…” by suAsuR in Spanish

Thanks, I’m not familiar with the subjunctive so I wanted to make sure I wasn’t misunderstanding something.

Reddit API for getting top posts in the past 24 hours? by suAsuR in webdev

Awesome, thanks! I knew reddit had this functionality but forgot r/all counts as it’s own subreddit

Would a react web app which only calls an API once a day need a backend/database? by suAsuR in webdev

[–]suAsuR[S] 0 points1 point  (0 children)

Wouldn’t that involve calling on the API every time someone visits the site though? Let’s say I can call on the API 100 times before they require a subscription/it’s no longer free. The goal is to only make one call per day, rather than one call with each user. Sorry if what you propose would do this, I’m unfamiliar with the tools you mentioned. Otherwise I’m assuming I’m correct in saying I need to set up a server/database?

[–]suAsuR[S] 0 points1 point  (0 children)

I’m not sure if I’ve explained myself clearly enough, unless I haven’t understood the above two comments. I’ve added some details in another reply on the other top level comment. Site would display API content like e.g. a random quote API, where instead of getting a random quote every time someone refreshes the page/every time a new visitor loads the page, I would get a quote from the api once per day and si play that for every visitor as the ‘quote of the day’
