The first '4' in 404 (and all 4xx errors) means the problem happened on the requesting (frontend) side, whereas a 5xx error means the problem happened on the backend.

[@bunnknees]

Amazing! Thank you!

[@deniscerri]

4 Four, Frontend 5 is and S, Server That's how I remember

[@barneylaurance1865]

Yes, although you can't necessarily trust the backend to tell you correctly whether it has a problem or not. So anything 4xx means the backend says there's a problem with the the request that was sent to it - but just like any other system or human there's a chance it's wrong. 5xx means not just that the backend is broken, but that the backend is prepared to *admit* to being broken. That really can't be wrong, since claiming to broken when it's not broken would itself be a form of brokennes.

It's interesting to see how quickly perspectives change. I was a programmer for years but never used stack overflow, but when I learned Basic, the internet didn't exist yet. We had to use books an people we knew in person. Cracked me up when he said he learned on C++ ("that's how old I am").

[@TheMoreGreen]

When I started out, it was already the early 2000s. I didn't have to read anything up in books but I am well familiar with going on page 16 of the Google search results. Instead of the StackOverflow being the dominant online forum, we had many different ones. My favorite answer to a problem, I've been looking up for 2 hours? "Is Google broken?"

[@neilgendzwill3260]

I learned Fortran using punch cards, then PDP-11 assembler. And I definitely use Stack Overflow. Why bang your head against the wall on some obscure problem when you can often find someone who has already solved it with a 10 second search?

Ten plus years ago, I was a TA (technically they called us section leaders) for Stanford's intro CS class and Chris was the head TA. Even back then and even when he was only talking to us TAs, he had this exact same genuine enthusiasm. When I heard he had become a professor, I knew he was perfect for it. And when this video popped up in my feed, I knew he would be perfect for it too! My most memorable experience with him was the time we were set to proctor a final exam and the professor no-showed; we had no exams. Chris was running around campus (literally) looking for him. Turns out the prof thought the exam was on a different day and hadn't even finished writing it. Chris had to explain what was going on to a room full of hundreds of stressed students. I think they ended up making the partial exam optional. It was a stressful morning but he handled it well!

[@KimberlyGreen]

What most people think of as "the Internet" is actually just "the web" ... a group of applications & services that use the actual Internet. The true Internet is a network of communication lines between computers, a language they use (called TCP/IP), and some rules for how they communicate. It's all structured a little bit like the telephone network, where all the telephones can call each other and make connections. Once a connection is established, information can pass between the two points. (In fact, some of the first computer networks actually used the telephone lines.) Once a couple of computers have established a connection over the Internet, they can exchange pieces of information, data, back and forth. Your mobile phone is actually a computer, so let's use that as an example. If you run an app on your phone, that app may need to talk to another computer to get some information. Let's say you are using Google Maps. Your mobile phone app will "call up" the Google Maps computer on the other side, using the Internet communication network. Once the connection is made, your app might say "Hey, I need directions to XYZ". What's really happening in the background is that your app took your human request, turned it into ones and zeros, and sent those digits to the computer on the other side of the communication connection, the Google Maps server. That server uses that request to understand how to reply. Then it sends its reply, as ones and zeros, to your mobile app. Your mobile app then turns those ones and zeros into a format that you, the user, can understand. The same thing happens when you use your web browser, play a person-to-person game over the network, send an email, or anything else you do "online". Just remember: Internet = communication network; Web = something useful that communicates _over_ the Internet.

I never thought of learning about coding and computer science this easy.Very informational and interesting video.

[@dickJohnsonpeter]

It's both easy and hard. In college you have to a lot of mathematics classes including calculus and learn the history of computers and learn all about computers and programming at the lowest levels as well as networks and a lot things I can't remember after all these years. Then you'll have to spend a couple more years learning your specific area of study, for me it was data analysis. That's on top of learning the gen ed/soft skill classes. On the other hand there are a ton of free courses and websites and tools to learn everything on your own, many even offer certifications. Many universities like Harvard and MIT put their classes up for anyone to see amd you can always go to your local university and sit in on any class. You can learn to code by just lessons online and it's not too difficult if you dedicate yourself for a year or two but to be good you want to learn everything related. The only thing you can't get for free is the piece of paper showing your degree and that's not actually as important as your skill in this field.

I can vouch for the self taught method. I flunked out of college three times. Heck, I _barely_ graduated high school because I'm bad at math. You don't need to know math to code. We write code so that the computer will do the math for us. I started by teaching myself basic computer repair which led to web design then networking. Eventually, I learned coding and more advanced stuff like database management and server management. I worked in the tech world for 20 years for companies like AOL, Gateway Computers, MSN, AT&T, and ADP. I'm probably giving away my age with those company names. But that's actually another good point. When I started, things like KZbin, Stack Overflow, and Free Code Camp didn't exist or were not at all as good as they are now. If I could do it in the late 90s and early aughts, anyone can do it now. As long as you can prove your knowledge to the person interviewing you, you'll be fine. Once you get the job, though, the most important thing, especially something like coding, is never stop learning. It changes so fast that you will forever be a student of your profession.

You don't need much math to code but if you want a degree in IT you need a lot of math

[@Reymon72]

Thanks for the insights!

[@jlang]

Thanks for sharing. I'm starting to think there is hope for me yet, despite my struggles with Python.

[@TheDeadFlashYT]

As a Data Scientist, I need a lot of math and probability

[@neanda]

That's very insightful, thank you, interesting story

[@Henry-fm6ql]

I love just how passionate he is answering theses questions. Honestly any person you invite on really taking the time to explain things in areas I’ve never thought about 10 out of 10 🙌🙌

[@corfe123]

This guy has some magic around him. I literally want to code right now just by listerning to his enthusiasm :) Love your channel!

[@alex_thecarguy]

This guy is very pleasant and highly comprehensive. It's impressive to be this detailed in technical discussion without coming across as condescending or giving a jargon overload, and he nails it. Really good guest and video.

Why couldn't all of my teachers be picked by WIRED. I would have enjoyed school so much more.

[@lolmomz]

Probably because teachers are not compensated nearly enough! Plus they have a whole bunch of other responsibilities

[@aborne]

I am a teacher. Here is why. Teaching takes energy, and sometimes we have to put that energy into other important parts of the teaching process. Presenting with energy? That’s just one part of the process. What they have here is a guy who was already prepared, and had very good energy and delivery. Sometimes, actually often - teachers can’t do all of this all at once.

[@Dr.Schnizzle]

If you go to Stanford you can at least have this guy 🤷‍♂️

[@eddy2561]

The often forgotten part of a web design team is the testers!! I can not tell you how many websites are so poorly designed when it comes to the user interface. Government websites are the worse of the worse, IMO

[@typeterson8376]

This also plays a little bit into the “hacking” portion because I think many of the people who want to get into hacking, are people who are interested in finding ways to break programs or make them behave in a way they aren’t supposed to. This kind of skill also translates really well into software testing

[@KaitouKaiju]

Well, there is a bit of a difference between QA and UX, though they often overlap

[@apnacollege7465]

Thanks for watching Search and join my Telegram for the right investment💯💯💯

[@Someone-lf7iz]

By far one of the best instructors I've ever had, if not the actual best. Teaching well is a gift, I wish all instructors had it!

[@DanDeGaston]

Personal comment: In response to "Do you need to be good at math to code?" I think Historically computer scientists needed to be good at math because memory and processing power was so much more limited so developing mathematically efficient algorithms was so much more important back in the day. Today, Computers have so much power, memory, and multiple processors that the majority of programmers don't need to be great at math. Just my personal thoughts on the movie. loved it.

[@Not-A-Content-Creator]

Well it’s not only in efficiency, for example, mathematical vectors are used in graphics, triangulation, and a couple other areas, but I would say if you have a hard time learning those then you’ll have a hard time reaching those levels, but rly anyone can learn mostly anything given time, dedication and perseverance.

[@syte_y]

to be honest it’s more so related to what domain you’re in. some domains require a lot of math others don’t. if you’re an ML researcher Id expect the person to know some level of math

[@nkosinathindlovu3059]

[@user-cd4tm9yj9m]

Chris is an amazinggg instructor. I truly enjoyed taking his CS109!! He is the best person delivering materials in normal and understandable language. Glad to see him on youtube :)

[@PoemedByTony]

What a Piech. He's amazing. Please bring him back!!! This was time well spent.

[@shahirsaleheen888]

this guys seems like a pleasure to be a student of. hope he continues to inspire for years to come in his life

[@dontknownothing8394]

I would go to all his lectures just for having a bit of his enthusiastic mood. Great teacher!

[@nicksligh3159]

Had Chris Piech as my professor Frosh Year and I can confirm he is literally the best teacher ever

[@meganofsherwood3665]

I love how many of the comments are "I had this guy as a teacher and he is phenomenal"

[@chaoticmonkiluv54]

One of the best classes I ever took was with him! Got me into CS and my career when I never thought I’d do anything remotely STEM-related

[@Jin420]

I would've loved to have him as my teacher when I was going to school for computer science. 💯

[@Errrrrr89]

I love how enthusiastically he explains.

[@labeeonrose]

I LOVE his enthusiasm about this. I wish I heard more people explaining things they love like this guy. THANK YOU

[@blancaluna572]

i love him, he made this difficult concepts seem so easy to understand, i bet it would be great to have him as a teacher

[@katiesmith537]

He explained everything so well and you can tell he loves what he teaches, great video!

[@Yasha_Masha]

Wow! He is one of the sweetest person I have ever seen on the Internet. You can feel his passions for Coding through the screen.

[@kirankornelireddy4136]

Wow what a surprise! I was a student at Code in Place, Stanford last year and he was one of the instructors. I love his teaching style and genuine humour. His lectures are fun filled. Good to see him again.

[@davidb50113]

I'm a UI Designer / front end developer and I could listen to this guy for hours , in fact I want this guy to narrate the rest of my life

[@echognomecal6742]

Nice to see someone so competent who's enthusiastic & skilled @ explaining.

[@chaoskaki]

I love how excited he is when explain everything

[@Sarah-re7cg]

Stack overflow is so great. It’s wonderful to get a different set of eyes on something or to search questions that have likely already been answered as well

[@shahana_style]

He's such a great teacher but I think what I love is how genuinely happy he seems to be explaining these things. His smile is infectious.

[@TessG9107]

I was lucky enough to be a part of Code in Place this spring. Chris is one of our two professors and that's why I clicked on this video. I love your passion for Computer Science. Thank you very much. I already miss Karel.

[@SoberDiogenes]

Chris sure has gone a long way since our times in ISKL in KL. Cool to see this.

[@hikkamorii]

7:00 fun fact, the reason why we use print when seemingly showing something on the terminal, is because back in the day instead of the screen, computers used teletypes that would print console output on paper. That is also why on unix systems your virtual consoles start with tty

[@sougat18]

Best 17 mins of life. Only we had such teachers who would take the effort to make things so interesting and simple that any can understand. Found a legend.

[@aznguyener]

Seeing his ability to teach concepts so well really shows the value of an education at a top tier school

[@toodapapa]

Of all these videos I've watched, he seems the most excited about his topic. Not that others seem unexcited, he's just more excited

[@Paul-uu7ek]

How cool is this guy! Spreading the joy of knowledge to other humans the way he does is really priceless

[@skullknightyt]

We need a part 2 of this. Very inspirational. Love the professor.

[@rotivo99]

This interview was fascinating!

[@JadaEbong]

Fun fact: Admiral Grace Hopper coined the term "debug" bc there was a literal bug in the computers tube and she said debug it She also invented the compiler!

[@francishunt562]

Think you mean COBOL, not a compiler.

[@JadaEbong]

@@francishunt562 no, she invented the first compiler but to be fair she also co-developed COBOL too
