Finally, David getting the recognition he deserves
I think people in tech world already know him pretty well. Specially because of CS50. Great course.
@@dhruvR.5724 Legit Apu. Man understands you even if English don't seem like your first language, know mean?
Yeah the Harvard job was a slap in the face. The Wired CZcams channel is on par with a Nobel though.
guy has old man sweaty pores.
About time 😊
I'm not saying this guy is smart, but computers come to him for information.
Take cs50
LOL
So he’s Chuck Norris? Got it lol.
Does he have an axe to grind with Amazon? He failed to mention them in the cloud computing question.
They actually do.
He’s not just “a computer scientist”. He’s THE computer scientist
What? lol
@@DanuxsyBasically, he's not just another random computer scientist. He's like a well known hero/teacher for CS students and beginners.
@@Danuxsy figure it out for yourself ffs
@@Danuxsywatch cs50, it's good.
@@bryanmavis8771 The "the" is certainly a little overly emphatic. Folk such as Professor Gerry Sussman aren't exactly chopped liver.
If you haven't taken his free CS50 course yet and want to learn computer science, I HIGHLY recommend it. His lectures are almost two hours long but he is so energetic and explains everything so well it goes by really fast. I've used his courses as supplements to my students when I taught high school as well. Glad he's getting the recognition he deserves!
You mean haven't
@@aditidumpoops fixed it haha
Is there a way to see his course online?
@@StyleMachineVideos it's free on edx
Where is the course?
This guy changed the life of so many beginners. We love you professor Malan!
Man!! he doesn't know how many lives he changed. CS50 2013 taught me a lot about programming, today I am a senior engineer
@@tobeyko Congrats, buddy! Did u take the course?
@@zuberkariye2299 Yes, I did.
More and more people will cause entry level jobs much harder to get as we’re experiencing now! They get filled up so fast and the competition rises and always will for the next big thing. More requirements will be put in place.
Sup brahms
Professor Malan’s CS50 lectures were used as the basis for my computer science courses at university. Thanks to his amazing lectures I have been working as an IT consulting professional for 5 years now. Truly inspiring professor. 🚀
Hello fellow CS50 student! CS50 taught me python and for that I am grateful to this man. Made the course so simple over CZcams!
Same! Started my career with CS50, learning C. Now I am an IT consultant too, great job, leading teams, doing system integratioN!
This guy's excitement is contagious. He has the gift of bringing fun to any scary-looking subject.
genetic privilege at works
@@Danuxsy by "genetic privilege" are you saying he's gifted/talented or are you saying he looks friendly?
all three of them I suppose.@@hiddendrifts
@@Danuxsy i was thinking you were referring to smth more specific
I would be scared if he told me we were going to have some fun.
This is my first time seeing Prof. David J. Malan outside of CS50x. It is thru him back in early 2014 via CS50x that I decided to take Computer Science at my local university because I loved how he delivered his lectures and was mesmerized by how he thought computer science back then. Fast forward to 2023 now, and I am now a Software Engineer with 5yr experience working for a US based multinational software development company that outsources some of its operations in the philippines and some other nations across the globe. 🥰

Boss baka tips Naman for us students in the same field?
I'm at the beginning of the same journey! Thanks for sharing your inspiring story!
I'm an IT professional, this guy explains things in a really great way.
He's a teacher at Harvard!
@@notsparktion More importantly, he teaches CS50, probably the best intro to computer science class in the world. I've watched most of it after I was already a software engineer for a decade and still found it fun and useful. This guy makes the class more like a documentary or a game show! It's awesome and available on youtube for free!
He's the professor and lecturer for one of the most popular introductory Computer Science courses at Harvard, CS50. The class has taken on a life of its own in and outside of the university, through the freely-available open courseware version. His down-to-earth clarity probably has a lot to do with its success as a popular teaching resource.
I think his answers here were half-baked. Almost there, but not quite all the way there.
Bro! He is a lecturer at Harvard University
As an Electrical Engineer, I have never seen someone answer these basic but fundamental questions in a more clear and comprehensive way without needing much visualization and in such a short time. Wow Kudos to you
He's a fantastic prof. Millions joined his online course for a reason 😉
Dude I could listen to this guy all day.
He teaches CS50 😸
Maybe because you’re an electrical engineer and he’s a computer scientist🗿
@@McFlashhyou must not have much experience in either cos theres a lot of overlap between the 2
Keep calling it Twitter.
The way he answers those basic questions without even thinking is insane🤯
Because sometimes the fundamental questions are tough to answer/explain adequately.
Yes I know the questions might be already spilled before the take, but his explanations are very easy to comprehend and therefore, it tells how great he is
This shows someone who doesn't know the world (how things & people behave) -- the OP is guessing & believing his guesses.
Prof. Malan did not answer these questions instantly ("without even thinking"). He had received the questions on twitter/X, and after thinking of his answer he answered each one on twitter/X. THEN, Wired asked him to make this video -- and we see his twitter/X answers next to his verbal explanations. He did not "instantly" answer any. He thought over time. He's not a god.
They are easy to comprehend but they're definitely not complete. He's doing a fantastic job though, it's impossible to give a complete answer to such big questions in such a small timeframe
without thinking lmao
@@shawnmuench He's going ultra instinct
Because there are prepared videos
As a computer science student I found this to be a very interesting and EXTREMELY well spoken "interview" that did a great job of answering these questions, no wonder he's a Harvard professor lol
Suddenly, I felt like I wanna study again 😂
AI will be a tool that dramatically improves the efficiency of programmers, which will mean even if not all programing jobs are lost, many will be.
Is computer science hard? I dont like math.
@@fynkozari9271 there isn't that much math, just the easy stuff, most of what you are gonna learn is stuff related to computers anyway. Don't get discouraged bro.
Takes me many, many years back when I first saw this man going crazy about computer science on CS50. I must thank him and his great first class for everything I have today!
Gradually I‘m convinced that David Malan is the only person who makes it possible for me to understand complex issues immediately without having to research them afterwards. The knowledge sticks. A living proof that it‘s not the subject that matters but the WAY you convey knowledge that build understanding
i've been taking the course CS50P for a few months and this guy is literally THE BEST teacher i have EVER encountered. i love him a little too much. when i saw this video on my homepage i literally gasped with delight and the biggest smile on my face. we need more passionate + engaging + authentic people like david malan teaching fr
Professor David just has a way of speaking that makes you wanna focus on every single word he says, and completely understand it. This guy is a gem.
Professional software engineer here. Professor Malan's CS 50 Intro to Computer Science course is considered the gold standard in the industry, one of which many of us recommend to anyone getting started in their CS careers.
David Malan is the reason I got into Computer Science 🦾
@@icemountaingamez 🤘
@@icemountaingamez same here
But as a professional software engineer, you do realize that his answer to the first question is wrong, don't you?
@@brinckau No. I realize that search engines do use distributed computing, among many other sophisticated techniques to be performant. So he's not wrong.
This man made me start Computer Science at University. His CS50x course taught me IT when I was unable to walk, and I begun studying when I got better
How are u doing know
@@aditidump Just fine. I was my uni year's representative for a while, am active in the student council, I'm helpful to my peers. Just lonely
I hope you are doing well
David Malan is one of the best if not the best teachers in the domain of Computer Science. His cs50x lectures built the base for my start as an undergrad CS student.
Much respect to you Professor.
David Malan is such a good professor, very passionate
As a CS major, and with almost 3 yoe, I knew everything but couldn't have explained it half as well as he did. Every single answer was so well put! Truly a great professor
Not completely. He got the first answer wrong. Search engines are ultra-fast mainly because of constant-time search algorithms, not distributed computing. If you search for "lasagna recipe" on Google, the search engine is not going to search through 8 billion webpages, using lots of computers to be faster (which is what this guy is implying). It will use an algorithm that will not need to go through each of those 8 billion webpages. This algorithm will give results in a constant time, whether there are 5 webpages or 8 billion.
He's not just answering questions, He's teaching us
As a person who finished CS50, this guy is probably the best educator I've ever witnessed, glad his passion is getting rewarded.
What a pleasant surprise to see Prof. Malan on here! I watched parts of his CS50 course a while back and loved his way of teaching and explaining things.
Met him when I took AP Comp Sci way back when. He visited our high school because we were one of the first public high schools to adopt the CS50 curriculum. Had him sign my phone case lmfao. Great guy
This man is an absolute legend and deserves all the recognition. One of the best teachers online and the best in his field imo
Next they should invite Linus tech tips
Im a computer scientists and knew the answers to those questions. Yet hearing David explain complex ideas with such clarity and simple words was a delight. Kudos to him !
We are proud of you.
Perhaps the best professor I've ever heard explaining a concept in ways that are so simple, yet so complete. I'm interested to hear any of his lectures that are available online.
For anyone looking at this comment at a later date, look up CS50 here on CZcams. It’s the actual Intro to Computer Science course that he teaches at Harvard, filmed professionally and uploaded for free.
David Malan makes me want to go back to college and study computer science. What a brilliant and engaging guy. I hope he writes a book one day.
He explained everything so well! When I was in college for CS during the 2000s all my tech profs are unenthusiastic and looked like they don't want to be there. Only one good prof and he taught graphics design. If only I had someone like him.
David Malan, the goat of Computer Science, helped millions of students through his goated CS50 course🙇
Man, I loved CS50 (HarvardX) with him as the instructor! I wish all our teachers and professors were as enthusiastic in explaining concepts as David is about Computer Science.
This man is the reason why i have a job today.
Not just that he's smart, but that he can explain things in such a relatable way and knows his stuff
i used to watch cs50 and this guy is a great teacher
So did I.
So did everyone else
no, never heard of cs50.@@oliver-04
Yes!
I got my first computer in 1979 and he did a great job explaining things. One of the first things I learned in early CS classes was binary and hexidecimal, I can still count by 16s
David Malan is hands down one of the coolest CS teachers out there. His CS50x lectures really got me going as a newbie software developer. Big shoutout to you, Professor! 🙌
This guy is definitely in his element. Very good at explaining stuff in an easy to digest and understand format. Thanks!
I completed Dr. Malan CS50 for computer science and Python. He is an amazing professor
As someone who already knew a lot of this I always love how refreshing it is to listen to not stale tech education
Excellent video, I loved all of the answers! The first one ("how are search engines so fast?") at its core also uses a surprisingly simple trick called "indexing." Search engines go over the entire internet, and keep books for each word they associate with a page - a page talks about names for orange cats? The page goes in the "cat", "orange", and "names" index lists. So when you search for "cat names", both the "cat" and "name" computers recommend the same page, and it shows up in your results - the engine doesn't have to look at every page on the Internet, just the ones it knows talk about cats, and the ones that talk about names. Of course there's more to it than that, and distributed computing is a massive part of it too.
Phenomenal answers across the board though - the speaker does an excellent job of presenting some pretty gnarly ideas in really easy to digest ways. Props!
Nicely explained
Starting my MS in computer science soon thanks to this man ... began with CS50 in 2020 ... thank you, Professor Malan!
I'm a Computer Engineer. Great video! Prof. Malan did a great job explaining every subject.
I'm taking Harvard's CS50 course, of which he is the host
You can realise a person's grip on a subject, based on how easily he can explain stuff..!
Really a Legend in my life...!!
What's with the ... before the !! ?
그냥 방송통신대에서 줌으로 수강해라..그지야
I followed David's IT free online course in 2020 and it was so fun! He's not just competent but also very clearly passionate about teaching, it's amazing to see him here!!
David Malan makes it feel like you've got your best friend teaching technology to you.
I have this man to thank for getting me started with python. He teaches in such an intuitive way.
He had to hit em with the *Hello World*
He’s not just “a computer scientist”. He’s THE computer scientist. He's not just answering questions, He's teaching us.
David is amazing! I took cs50x and the dude is a brilliant teacher. Harvard should want to keep him at all costs. If I ever meet him in person I will want to give him a hug as a thank you.
The idea of working along side these innovations, as tools in our belt, as opposed to replacing us, is the best way I’ve found to cope with rapid technological change. This sentiment needs to be uttered more!
Yes you're right.. it makes a scary future more approachable
His passion for computers is so clearly visible in his sweat that he has while explaining things look at the cs5o course, prof Malan is always sweating and it really does show his enthusiasm and passion for computers and teaching he is probably the best teacher to exist right now.
or computers are just hot
Haha it's his uniform-that black sweater he'll always wear, or sub out for a long sleeve in the summer here!
@@mugensekaihaha makes sense now
is the long sleeve and the extremely fast speaking
I stumbled upon his CS50 class online and got so into it, it basically turned my life around I am now back in school to become a developer. Truly inspiring, great talent, both in computer science and in teaching !
David Malan is quite possibly one of the best educators out there. I'm a CS grad with near 20 years as a systems software engineer and I thought I broke things down into simple terms, but this guy really nails it; he understands what people don't understand about computer science without rapidly taking them down a rabbit hole and explains things concisely and accurately. Bravo!
I really love how he explains anything with a way that is easy for anyone to understand while keeps you interested
David is class. I took his CS50 course and hands down one of the best lecturers out there! Great to see him being recognised finally
This guy does a great job not only explaining things in an understandable way, BUT doing so in a positive and neutral way. And I think that positivity is the most important thing. Ie., someone could explain these topics in a way that’s easy to understand but with a negative tone (starting flame war RE: best OS, etc.). This guy is great.
The idea of computer science really is the combination of mathematics and logic to create automated systems with computers to solve problems. A typical kind of problem that a computer scientist would need to solve is how to identify, keep track of, and search through a massive list of items in a database. We would use code to tell the computer what the system we designed is, but the real skill is knowing how to design a good system in the first place.
I love you guys for still calling twitter twitter and using proper logo
Keep it this way
It is never going to be X
@@iluvpandas2755 NEVER
How come wired get such great professionals.

@@levishkatishka3513 🗿🗿🗿
CZcams pays more than you probably think it does, especially when you have 10 million subs. Wired has a lot of resources to allow them to headhunt and interview a lot of professionals.
@@Eadric_The_Wild is he the guy on CS50?
If u attended CS50, u could answer most questions here. The way he explains the concepts is amazing. Thanks to u Prof., I'm programming my first app.
I love David so much. His passion for teaching and comp science keeps me going. Every now and then i go back to CS50 and he brightens my perspective up.
Guy's doing a great job at simplifying his answers. 👍
he's OVER simplifying it, making the answers not make sense anymore if you have a little bit of advanced knowledge. then his answers are even wrong sometimes.
@@iWhackowhich of the answers don't make sense and/or are wrong?
@@iWhacko And what if he said it accurately? Then it wouldn't be interesting and easy to understand anymore; which is stupid to do if you want to teach people basic concepts.
For example, why do people keep teaching Newton's laws at school? Why don't they just teach quantum physics and relativity theory, which are more up-to-date and accurate when explaining movements and gravity, at an elementary school? If you know that Prof. David is oversimplifying stuff, I bet you would know the answer to my question.
@@vibinmikegothyped3270 Well for instance the first question: "Why are search engines so fast?" he says its about distributed computing. which is true IS a factor. But a single computer search engine can be just as fast, maybe faster because it's not talking to other computers. The reason search engines are fast is because of indexing, just like the index in a dictionary, it can look it up real fast based on the page number.
See?? still easy to understand, and Actually correct.
@@iWhacko That might be true, but I don't have any qualifications as well as the essential knowledge to "fact-check" your statement. So I'll just give you the benefit of the doubt and believe that you're an expert in this field who knows better. And I mean it.
He's one of the best (if not the best) teachers on the planet! I love the way he teaches cs50
I can listen to him for hours and never be bored even for a second! David is just amazing!
I came here just to watch him teach again, the way he teaches changed my life, literally.
This guy is really good. You can tell he is a great educator. He has a positive future on the internet.
The way he explains and his general excitement is so excellent!
I took one of his CS classes and it was easily one of the best I've ever had in any subject / focus area. Great professor and great explanation of concepts
This absolute legend kickstarted my and many others' coding journey. What an guy.
Just curious, when did yours start? :)
Very engaging teacher! Pleasure to listen to him and he takes very complex topics and makes them understandable.
Still convinced that Web 3.0 is just a marketing term for crypto stuff tbh
I have been part of his lectures. This is how not just computer science but anything should be taught. He is super inspiring. Thanks professor
This guy explains a lot of complex things in a very simple and great way.
Such a well spoken guy.👏👏 Thank you Wired for finding intelligent people like him who are not only smart but can communicate effectively and get their point across without boring us.
Wow. He talks really fast. If I was in his class, i guarantee the whiteboard will be erased before I get to jot down my notes! However, i wished some of my lecturers were as passionate and energetic as he is. I can listen to him talk for hours and not be confused.
You can join his classes. Search for CS50 by Harvard. They are freely available for all
This guys computer science courses are absolutely insane. Easily one of the best teachers i've seen.
Most likely the best professor I have ever seen. I have attended university, cisco (and a dozen other vendors) training and I must say: after watching this guy classes online when was being introduced to programming I keep him as the "benchmark" for professors.
A comment for the people that wrote the English (US) captions
At 1:49 he says "you and I" and the captions are "You and AI".
I'm not trying to criticise this small thing, but I really read captions while watching this to make more sense of the information, and it had me confused enough to miss the next 10s of information.
Just giving some feedback 🎉
Great content overall here by the way, amazing video 🎉
As a software developer, I didn't learn much, but I can appreciate how he managed to simplify very complex ideas. Great explanations overall.
Oh I didn't learn much I'm so smart tatatata
@@evangreavu9621he is right tho
As an another software dev, I also didn't learn much. It's interesting seeing a wired interview in a field you already know.
I always love seeing David J. Malan explaining concepts in Computer Science
I had CS in high school and back then i had problems understanding Java. I'm currently doing CS50 and just finished C. It is incredible to me how much easier it was to learn C than Java and given that everyone says C is generally harder than Java, it really goes to show how well structured Malans course is and how important the teacher is. He is not just good at explaining complicated concepts but also preemptively answersvquestions that beginners will naturally have.
Oxford, Harvard, Stanford and other top Universities really does have a reason being the TOP. This guy is one of the reasons!
I happened to have the opportunity to experience a former Lecturer of Oxford University lecturing biology(entomology) and hollyyyyy sshiiiiii*tt it's that GOOD!!! Their way of presenting concrete complex information is by far the best I ever have in my whole life.
I really respect this instructor, the way he's explaining things is just amazing and very creative.
Cybersecurity analyst here and Professor Malan is an excellent ambassador for the field and study of computer science. He does a fantastic job of putting imagery and concepts that make sense in your head in display on a monitor. Great answers for all of the questions!
10:50, what a brilliant but simple way of explaining memory allocation in computers and how it's deleted, stored, and what is the purpose of transistors and capacitors in a computing system all in one analogy. Great!
Wow, one of the best Wired support vids I've seen. David is so informative and clear
I've had bad teachers all my life.
This guy is amazing just 'cause he's simple in explaining.
Someone said "The top of sophistication is SIMPLICITY"!
He's the only reason I want that certification of Harvard. This guy I want to hear, watch and learn.
Maybe I'm biased because he said Harvard, but this man is the greatest teacher ever, not just in the way he is able to explain things for beginners to understand but there is almost not inaccuracy in what he is saying. Most people when simplifying concepts like the ones he is talking about tend to introduce a lot of inaccuracies, but I didn't detect any in the concepts I already knew.
I love this guy. He spreads his excitement to everyone even to ordinary people.
happy seeing David here !
but where do we go to ask the questions for wired
?
If you loved this video i hope people go and wach CS50 courses that David himself teaches with the same fun style he shows here
Im a grad in Computer Science and I must say this professor has his basics down better than Ive seen in any other.
Explaining something incredibly complex so that a non professional can understand it is an art of its own. Thank you David.
God I am so happy this man is finally getting the recognition he deserves. You're awesome, Professor David!
i wish i had this dude as my comp sci professor.
great dude, he should start a course on "introduction to computer science"
I took his class! Honestly the most energetic and passionate lecturer.
