Learned more in this 1 video than my entire degree at Montana State. Never knew teachers like this existed!

@manitshah1881 3 месяца назад

Came here for 5 minutes. Stayed here for 150 - even though I was already comfortable with all these languages. Simply fabulous teaching of the highest quality. Professor Malan - Please never stop! Also, if you ever decide to take requests, a deep-dive into SQL (beyond just lecture 7) would be awesome.

@junhuama68 27 дней назад

At 2:17:00 would it be better to use "const" instead of "let"?

@anita.popovic 3 месяца назад

Down to basics lecture where emphasis is on entry level coding for all segments and then JavaScript which IMHO is more important in this context (compared to HTML and CSS anyway) is somewhat glossed over at the very end. Anyway, to whom it may concern, since the lecturer seems to be a stickler for good form and syntax, which he definitely should be, the example html file hello3 should be corrected to align with hello2 where as the lecturer says the "annonymous function" that "apparently takes an argument as input called event" the event argument is included but it is excluded in the hello3 version and is renamed to e. Both can perhaps be confusing. for some with no prior experience whatsoever.

@maxxx973 3 месяца назад

Yes, its kindda confused about the JS part especially for no prior people, I think the "e" and "event" argument is set deliberately to tell people its just a arg of a callback fuction which includes a preventDefault() method of a event

Can we get certificate for this course?

@Polaris_Babylon 3 месяца назад

Yes, it's on edX!

@enisten 3 месяца назад

Yes, but I've seen reviews of this course where people recommend that you don't pay for the edx certificate because Harvard already gives you a free certificate upon completion. I just don't know if you need to take it on the cs50 website or you get the free Harvard certificate even if you audit it on the edx website. Maybe someone who knows can clarify?

@antonipokrzywa4776 2 месяца назад

@n I've made entire course on website (cs50.harvard) and received cert. I was just in case enrolled on edX (but its free), the only one benefit that u get from the paid one is that they check your final project and get a slightly better certificate. But it won't get u a job anyways so saving your money is a great option.

You need to ask if anyone in the audience is epileptic before showing them a simulation of the "blink" tag, as that is one of the reasons it was removed in the first place. RU-vid needs to add a photosensitive warning to this video. Please remove it from your future lectures.

@enisten 3 месяца назад

Where is it?

@FlorentChardevel 3 месяца назад

The implementation he shows seems very safe to me, as it's just a small black text blinking slowly on a white background. I'm not epileptic but I don't think there's any risk in this part of the video.
