Lex, honestly...you have emerged from your seemingly weird, obscure, uncomfortable self (which I always felt I could relate to) and blossomed into this loose, entertaining, funny, outgoing self! (New you or Highly edited?) And...The commercials are hilarious...very personable and you represent the product well. I suddenly want Raycon ear buds and a new bed...keep expanding your horizons, working out beyond belief, exceeding expectations and being a great inspiration (especially for me). Much luv

The C programming language. I was taught C in 1981, I live in the UK, I moved to NY in 1981 to a place called Summit NJ, little did I know it was only 4 miles from the temple of AT&T Bell labs. I have been using c/C++ ever since. It gave me my career. Thank you K&R.

[@shanefelkel9966]

Brian Kernighan is always such a gracious and fun guest to listen to. He really conveys his love for the science/art of programming, and his archival knowledge of the earlier era he helped to shape is really invaluable. Beyond that, there are two points I'd like to comment on: (1) It may be because I'm older, but it always amuses me when younger generations aren't aware of the technologies and utilities that the current technologies are built on or have superseded, especially when they work in those affected fields. Now here, Lex may be taking some narrative license for the benefit of his audience, in that he asks questions that may seem like he should know the answer to or be familiar with (as he always does his research), but because of his youth, he may not actually be aware of some of the history. But then, I grew up with rotary dial telephones, black and white televisions, no video games (until Pong), etc. No slight to Lex, it's just a little humorous to me I guess, in that historical technology is somewhat forgotten or ash-canned, unlike social or political history. Also, it makes me feel a little closer connection to Brian or anyone of that era because I lived through the days of punch cards, 4 and 8 bit processors, 16K memory, TRS-80s, and no "mice"! (2) I'm surprised Brian didn't mention the Perl programming language or if he ever used it much since it came out. I watched him on a Computerphile video where he said Larry Wall developed it in response to the lag in waiting for the second(?) version of AWK to be released to the public. But he added that Perl had become so much more. Just wondered if he just never really had a use for it, or if he'd moved on from it, or if there was some mild animosity to it? I love it myself, but I seem to be in a shrinking minority. Okay, one further point (and slightly off-topic comment): Number one on my tech wish list is for the advancement in battery technology. Put everything else on hold til this is done. Tired of having to charge stuff up all the time - usually concurrently. Phone, watch, portable wifi, and laptop always gulping up the juice. Some of it is software's fault for being too bloated and resource hungry. Second wish list item is lets have some equilibrium where hardware advances can let us coast for awhile before software "advances" bog it right back down again (remember bloat?). Third wish list item is somebody please develop the 30 year operating system so we don't keep upgrading ad infinitum. K, cheers! Good vid.

[@mt-qc2qh]

I learned C right after programming in DG assembly language and still have the first print edition of The C Language on my book shelf. Personally I can't express my enjoyment of listening to this interview. I still use C/C++ today as my favorite language after many tangents to other languages throughout my 47 year career as a systems engineer.

[@fredericbrown8871]

I did the opposite: learned C first (back in high school or college, to program my graphing calculator), then assembly (z/Architecture). The insight about how memory is allocated and mapped you get from C was invaluable to understand how things can be implemented at the machine level. I'm still amazed at how that language strikes what's probably as close as you can get to the optimal balance between abstraction (practical expressivity, clarity, portability) and close mapping to a stored-program computer architecture (theoretical expressivity, efficiency). In addition to that, plain C (without awkward extension) is a very elegant language, IMHO (nothing to add, nothing to remove as attributed to Saint-Exupery, plus rien à ajouter, [...] plus rien à retrancher). As I've already sidetracked, I might as well add that I even took the habit to comment operations and control structures in my assembly programs using C, like that (real code snippet, comments have been translated to English): * nbEntrees => R7 : Numbre of entries read. * ptrTable => R9 : Pointer to entries' table. NB 2022: I should have added that sizeof(struct entry) is 20 bytes in that comment for later. * do { LOOP1 EQU * * Read record in buffer (R1 -> buffer) NB 2022: GET is probably a built-in assembly macro from what I remember... GET FICHIN * Copy 20 bytes from read buffer to ptrTable MVC 0(20,R9),0(R1) * ptrTable++; //NB 2022: Yeah, LA is for LOAD ADDRESS but was wildly used for simple integer arithmetic and perfect for pointer stuff like that. LA R9,20(0,R9) * nbEntrees++; LA R7,1(0,R7) * } while(true) /* ON_EOF handle branch to ENDB1 when * last record is reached. */ B LOOP1

[@brunoribaric9683]

Kernighan massively downplays his role in projects he's worked on, every single time. That's interesting.

[@darylallen2485]

It's the mark of a man whose done his best work and worked along side other better and more talented people. In particular, he seems to circle back to Ken Thompson a lot. Ken sounds like he was a genius who was way ahead of his time. I bet he spent a lot of time being frustrated by having to interact with morons who would never be able to comprehend the ideas in his head. Most of us can't comprehend his ideas after they left his head.

[@haythamkenway8675]

[@solderbuff]

@@darylallen2485 , lol, Thompson is just a geek who likes to play computer games. He is a very talented programmer indeed, with great structured code, but he is not a genius. Most of the ideas he used in Unix came from other people's research.

[@darylallen2485]

@@solderbuff I get what you're saying. Sure, there were probably smarter and more knowledgeable people in the field of computing and academia. The Wright brothers were high school drop outs. They invented flight while academia theorized and hypothesize the notion. I'm sure many contemporaries of the Wright brothers were smarter and produced some contributing research. At the end of the day, two highschool drop outs were first to build a flying craft. In my mind, Ken Thompson is a genius like that. Maybe there were some people of his day who were better at theorizing and researching. Ken got his hands dirty and made things to impact the real world. I think it's a kind of genius that gets downplayed by academics. I consider him a genius and an inspiration.

[@solderbuff]

@@darylallen2485 , yeah, I agree here. Thompson is closer to Wright brothers. While others were building great castles out of sand (Multics), Thompson built a steady brick barn that is Unix. Thompson and the others at Bell Labs struggled to keep it as simple as possible. And even though many at the time thought that Unix is inferior to other operating systems, the simplicity of Unix (and C) is exactly what allowed it to become so widely adapted. There is this ingenuity of simplicity.

[@TheEvertw]

For those who have never worked with them, the original TTYs were very different from any other type of user interface. It consisted of a type writer where the printing and the keyboard are disconnected. You talk to the computer using the keyboard, and the computer talks back by printing stuff. This was usually chained paper, i.e. the result would not be loose sheets but a long scroll that could be folded. One of the main differences is that this automatically logs your interactions with the computer. Everything is stored right there on the paper. This means that e.g. text editors did not have to provide the whole context of a file, allow scrolling etc. Because you can print the file once and physically scroll back to it on the paper scroll produced by the printer.

"MS-DOS was a pretty pathetic operating system". Precise words....

[@mecca831]

40:21

[@afterthesmash]

MS-DOS was no worse than the machine it was running on. When the IBM PC was introduced, memory was USD $3500 per megabyte (inflation adjusted to 2020) from the cheapest source recorded (this was not server-grade memory). Nobody had even heard of gigabytes. ¶ This is why the IBM PC wouldn't even accept 1 MB of primary RAM. The price of consumer DRAM began to plummet after the introduction of the IBM PC and it was only about 1/3 as much a year later, especially of memory expansion boards that went beyond the amount of memory you could address normally. For extended or expanded memory, you had to set commands to IO ports to switch different banks of expansion memory into addressable space; this was slow and broke your pointers. Later on, people would buy 3 MB of memory and devote the whole thing to disk caching (the hard drives were also brutally slow) and not even try to use this memory for applications. ¶ You couldn't reasonably time share (or multitask) at this price of memory unless a professional group of people bought a minicomputer collectively. Everyone who criticized the PC was used to a professional system from work or academia. ¶ I'm presently sitting in front of a FreeBSD machine with 16 GB that punted my entire desktop yesterday because it ran out of swap space. The only two programs I was running of any significance were Firefox and Thunderbird. I use FreeBSD because I like ZFS. I've never even tried to run ZFS in a system with less than 8 GB. A decent computing facility with 8 GB of memory back in 1984 would have cost USD $85 million for the memory alone (after you triple the price from consumer memory to server memory). ZFS uses 8 GB on my desktop system basically as a glorified disk cache (more for integrity reasons than anything). ¶ The more things change, the more they stay the same. ¶ Check out the memory price history at jcmit.net (note that they are not inflation adjusted). ¶ In any case, my memory woes should be short lived. I'm awaiting 64 GB of ECC memory I purchased used from Houston for USD $2/GB. Then I can swap the 16 GB of memory I presently have in my NAS box into my desktop system (they are both IBM Thinkstations). It will be just like the first time I upgraded from 256 KiB to 640 KiB on the IBM PC. Like xmas morning all over again. I can hardly wait. ¶ [*] But wait I shall have to do, because the memory went from Houston via USPS to the Pitney Bowes collection center in Erlanger, Kentucky where it sat for a week. I'm pretty sure it's now sitting on some railway siding, after taking a CP freight train from Chicago to Minneapolis to Fargo to Moose Jaw. Canadian Pacific still owns a big chunk of the rail system down there, called the Soo line. And then another long leg from Moose Jaw to Vancouver. Rail is about 1/3 of the price per ton-mile over long-haul trucking. And then a fairy to the island. 3500 miles. What did they charge me to shepherd my 0.78 lb package the effective distance from Lisbon, Portugal to Tbilisi, Georgia? USD $15. ¶ Back in the 1200s, Marco Polo travelled 5600 miles in this general direction, but it took him 3.5 years-about the same length of time it took the IBM PC to compile a large C program if you didn't install a disk cache.

[@Argletrough]

Lex, thank you! What a great interview with such a wonderful gentleman. Really took me back to the days of magic when the emergence of microprocessors was changing not only how we engineered products, but society as a whole. Loved the discussion on assembly language. In 1978, the year "The C Programming Language" was published, a friend and I launched a startup. We were using an Intel 8048 for an embedded design. With 64 ram and 1k rom assembly was the only option. I loved the challenge and the "one to one" correspondence to the machine. It was tedious, and occasionally frightening when late at night we feared maybe what we we're trying to do was "impossible". When Brian answered, "when you built something and it worked" I can relate. Anyway, in the '80's when C for micro-controllers was finally an option my first C text was Brian's book. Thank you for introducing me to the man. He does not disappoint.

They're talking about the days I started in. I was in high school when I first came face to face with my first Time Sharing system... the GE-265. I worked with a group of guys who would go out and acquire systems that had become obsolete from the mid-60s and we'd bring them into an air conditioned warehouse and get them running again, and sell time on the time sharing systems. This was an all black business in a black neighborhood mind you. We'd teach classes in computer programming to young students who were interested in such things back then. It went on for a couple of years, but the problem was we were on the cusp of the end of the minicomputer/mainframe age and the beginning of the "Microcomputer" age, these days known as the personal computer. The Apple II killed us. I went on to become heavily involved in the DEC PDP world, using operating systems like UNIX, RSTS, and RSX-11. Then VAX/VMS. Then Apple did it to me again. A friend showed me what I had once called a stupid little Etch-A-Sketch computer called the Macintosh. My life was interrupted. Since then not a day has gone by where I haven't had a Mac in front of me. I'm 65 years old now and even though technically "retired" I still earn a living through freelance coding and remote system/network administration. People ask how I know so much about computers being so old and I explain that it is difficult for me to remember a day that I wasn't in front of some kind of keyboard since 1975. I have two MacBook Pro M1/Max machines in front of me right now, and I'm building a new a new Apache James mail server for a client. Never tell kids you've forgotten more about computers than they currently know. They don't quite get it. They think you mean you've got Biden Brain.

WE first must “move beyond” [{**}] the ORDER of these OLD WINE SKINS, and talk to our selves as NEW WINE SKINS being our Inner Voices and our “Inner thoughts” that come from The Symbiots [{*}] of The Construct we are all Born into at CONCEPTION……..., not the day our Flesh, and Blood, and Bones comes out of the Wombman… We must “know” we are in A Bio - Binary System where ZERO ONE become the foundation blocks of THE GREAT WORK…….., and we must see that many do not want to OWN what they have done……., so they can be REDEEMED “when they die” / * \ too this Celestial Sphere Home World known as PURGATORY cause [they think} they got an out…..., or a Scrape Goat….., or a LOOP HOLE for These {10 Commandments] that make so much more sense in our FLAT EARTH Reality where Mother is the DOME OF THE ROCK…., and OUR Father is these hallowed ground we come from…, and return to.., and once you can see this “Book of Books” the Biblical known as The Holy Bible., then the Commandment RESPECT your Mother and Father that {your days} /-\ may go well in this life means: Take care of the Sky, and the Seas, and the Lands... Do not fill them with Destruction, and Damnation where WAR IS MURDER is all you will every know!!!

I do not think any of you would want to be Hunted by the U.S. UNITED NATION World Police, and then have them Skin you, and Cut [your head] off like in that Scream and Shout Britney and Mr. Smith Video!!! Then why must you people HUNT Animals for SPORT.?.?.? It is not wrong to “feed” your people and yourself……., but when you Hunt an animal, you are also hunting the SOLIDS in them, the Symbiots in them, and the SPIRITS in them as all life matters……, and all life is SPIRIT… Now, you might “appreciate” why Fur Coats made of the Bashed in heads of Baby Seals is something only EVIL SPIRITS aka Anti-Christ People would do….., for they seek Fame, and Fortune, and Glory, so they want to do WAR IS MURDER when War is against the RULE OF LAW…., but just give (a little mind) some ink on paper, and they will write books that WE THE PEOPLE have the right to Hunt you “into extinction” cause The U.N. Says: This FLAG is allowed to Hunt, and Rape, and Murder all of [these people] under that flag, and you would do well not to FEAR such people, but {pity them} in their sickness of mind, soul, and actions… Remember these PEOPLE whom hunt for SPORT and not food are The Racka, and of Pak-Toe will have nothing to do with The Cursed, The Forsaken, and The Dammed for their JUDGMENT “is evident” in THE WAYS they have lived their lives, and how they Worship S.A.T.A.N. aka WAR IS MURDER….. You see we want to go HOME when we die, not repeat the Curse of Things like them “Bones Buckets” that hang from Dead Trees…. The Book of EXODICE!!!

Great podcast. Always consider him as the Master. I started with C. One of the first and the best book I read in programming is The C Programming Language by Kernighan & Ritchie...Thanks a lot Lex Fridman..

[@rsassine]

At around 18:55 when Brian Kernighan talked about how hard it is to write in assembly I remembered my first computer job back in 1978 was to figure out why 'something' was not working the way it should. Well, after a few days of search, I pinpoint where the problem is. It turned out that the original programmer commented this "I don't know why the next 10 lines works". After the 10th line he/she wrote "I don't know why the above 10 lines worked". Boy! Did I have a blast. Yes. Assembly coding is challenging.

[@silvernode]

Thank you for having Brian on your podcast Lex . Can you please see what you can do to get some more of the greats of computer science? I would like to see Linus Torvalds, Richard Stallman, Ken Thompson and Eric S. Raymond. Keep up the good work, and I too think you should rename the podcast to "The Lex Podcast".

Brian is so humble! Not my first time listening to Lex or Brian but what a great interview!

[@davepatrick7848]

Thanks for having Brian on your channel. I have purchased the K&R book on C a dozen times since my intro in 1981. I either lost or gave a copy away over the decades!

[@abhishekshah11]

While Brian was describing awk, I pulled up the man page for awk and was surprised to see how similar the words he uses to describe them are to the man page.

[@sunderchakra]

Loved the chat . The C book with illustrative examples and crisp reference is an all time classic. Ed line editor , nroff - gems indeed. Have not used these for many years. But still use perl and make .

[@kahnfatman]

This channel and the likes should be called Computer Science Appreciation.

[@andrewtechful]

That was an incredible interview! It's so inspiring to see how humble Brian is about the remarkable work he has done.

[@dantealighieri6613]

Absolute legend, his contributions to computing and programming are on par with Sir Ritchie.

[@eliodecolli]

History of CS is amazing, you should invite more people to talk about this. Mainly old generations of programmers.

[@thanhavictus]

Wow. I had no idea he was still alive let alone this youthful and enthusiastic. What a legend

[@torarinvik4920]

Im paraphrasing, but I think the saying goes something like "An intellectual is someone who makes something easy hard, an artist makes something hard easy." Good way to describe Brians books, so well written and explained.

[@mytechnotalent]

Brian Kernighan is one of the most influential leaders in Computer Science of all time!

Lex, you did a great job interviewing Brian. Thanks for posting this!

[@SanjeevSharma-vk1yo]

I learned LISP (actually SCHEME) around 5 years after I got out of full time programming (C, PERL, SQL) So the language one loves most IMHO is independent what one grows up with (or learns first).

This is easily your best interview.

"Are you kidding? We did it in Troff" "I don't even know what that is" "Yeah, precisely" That made me laugh, if for no other reason than I'm demonstrably a child of the late 1970's at Berkeley, given that I had to mark up my dissertation in troff.

[@dmitripogosian5084]

I have one of my first scientific paper as a graduate student, back in USSR, in troff (or nroff)

[@RhettAnderson]

Lex, if you code assembly language all the time you get into a groove. I coded assembly for commercial games into the 90s. It's difficult but not as hard as you think.

[@anant6778]

If you code C all the time you get into a groove. I then had to go back to python (which I already knew) because school was teaching python ... its very difficult and non-intuitive, at least for the first few days

[@RhettAnderson]

@@anant6778 I have definitely been in the C groove before.

@@RhettAnderson To be very honest, thats not my gripe, but using whitespace and indentation as syntax rather than just good practise for readability is where my contentions lie. Its atrocious.

Thank you for this. Brian mentioned troff was before you were born. We need to interview all these old timers who where around at the beginning and ask all these great questions about what it as like and what they think is important and their perceptions before these pioneers die off to keep a historical record. Brian is one of these Gods. Is he wearing a Casio watch?
