Remember that the German navy took it further and had four rotors, on its' machines. The messages would also be in groups of letters that would correspond to code words in their code books. You described the bombes very clearly and the Python simulation looks concise. Thank you.

How did the government repay their gratitude for him winning the war? By driving him to suicide. Fucking disgraceful.

In 2004 I took a cab from the airport to home, the cab driver told me he used to be a COBOL programmer who worked for a bank.

Got part way to the moon, then the system shut down and the pilots landed it without computer assistance. People are blowing what the women did out of all proportion BECAUSE they are black american women..its completely trying to overshadow the female programmers who predate them by decades and in one notable case 2 fucking centuries.

I was forced to learn COBOL in around 1990 as part of my computing degree. It was the primary language we learnt. Thankfully in the following carrier of 30 years I was never required to even look at a single line of COBOL ever. My memory of this language is that it forced you to write well structured code with an understandable program flow. I worked 15 years in the banking industry but never got near cobol code although we new it was there 🤠

Moon landing.....lol....& those running the show call it a Plan IT.....for a Reason....possibly

I worked in COBOL during first IT job, but I changed track as it wasnt something I was interested in. I take of backend architecture today and APIs and cloud. But to be honest even today I remember COBOL and I dont think it is hard for me to work on it if some one asks me to. And to me the very reason which keeps it alive today is the very reason why I wanted to change to other areas of my interests.. its very basic and simple. And something very basic and simple is what is preferred by systems that are expensive. And it also adds security. when things become too nested with concepts like oops, functional programming and all that... it also requires great deal of attention to detail to design to make it all fool proof and have it updated as industry changes.

Nice bit of code

Thanks Ma'am, you have made my day!

this story is a good example of responsibility. What should be done with the informations? Save a convoy and risk that the the german realize what is going on or use the informations very very carefully. They decided to go choose the second option witch obviously worked. BTW 30.000 civilian sailors where killed in the so called battle of the atlantic.

never forget that the enigma is a mechanical device working under extreme condition

other themes around Eniga Gordon Welchmann the film imitation game mr and mrs friedmann the story about breaking japanese codes

solution is simple, build a new bank ;-) Not cheap but the only way to avoid all these little traps

Add Glide too in the list

COBOL invented self documenting software. That’s why it’s still in use.

This is absolutely THEE best video showing what a Data Analyst does. 🎯 Ms. Dee can’t thank you enough.

the biggest problem is Flutter. Avoid it.

Cobol is dead easy but not something I'd like to touch now. One of the main reasons Cobol programs are still in production use in banks, with no intent to replace them (and only a handful of people to maintain them) is because nobody has been able to, with 100% certainty, replicate how Cobol does decimal computations natively. Floating point is not a substitute.

Que all the "we never went to the moon losers"

1202… overload…. So restart! In the middle of landing! 😱

Hello? We are still here, I'm a relic of the Y2K scare, which BTW was questionable. Anyhow we are still alive and the last of us are about to retire

I think RUclips wants to deter people from watching your video. I had to mute the PC and make tea for nearly five minutes to get through the ads that Adblock seems no longer capable of dealing with. Perhaps someone could use COBOL to make a better Adblock for Firefox?

As presented very factual, EXCEPT that for several years afterwards Turing developed an entirely and perfectly satisfactory COMPUTATIONAL THEORY AND IT'S INITIAL IMPLEMENTATION IN SOFTWARE (written by Bernard Richards) of MORPHOGENESIS! Well, that's a fact! Simples... (:-)

tell me this video was AI generated

This is a fascinating video. In the past I've watch many videos and read books on this subject. As you was explaining the workings of the rotors and cipher along with the mention of a flaw, I started to think - WEP, WPA/2/3 and the word word for CAPTCHA, - A Completely Automated Public Turing Test To Tell Computers and Humans Apart. Alan Turing is always with computers and coding and part of our daily lives. Great presention and thank you for sharing.

There are thousands of people who can code in COBOL. Also ChatGPT

In the movie "Apollo 13" they said the "the astronaut is the most visible person in the structure of thousand of enginneers".

I once met a heavy-duty equipment salesman. He told me that there are thousands of farmers in America who still use circa 1970s John Deer and Caterpillar equipment. The newer equipment he sells is definitely better in many ways, but not enough so for farmers to give up what they already own, know how to use, fix and trust. He said some of the old equipment was built so tough that as long as you maintain it, it will never die. When something survives for a long time, there is a reason for it. With all of that said, the way COBOL is structured, in matter of years AIs will be able to port a lot of COBOL programs.

I wrote an assembler when I started work back in the 70s, but my boss had written such a good suite of libraries that was actually quite a high level.

agile is just a term to cover up the fact that nobody wants good design and QA anymore, let's 'wing it' and call it 'agile'.

You got me. Thought the thumbnail was meghan markle. Nice try

"The World Depends on 60-Year-Old Code" Well, actually the world depends on the gravity of the sun. Yeah, I used to program some COBOL. It's awful. BUT, if you can get it to finally compile, it will probably work fine for the next 40 years.

"the engineering manager ... and the SCRUM master were very much against the idea [of less SCRUM meetings]". Well, SCRUM masters or engineering managers are normally not computer science guys or girls. I know the case of a company using external, freelancing SCRUM masters. They were payed by the hour. No wonder that these "high priests of SCRUM" wanted to have more meetings.

Excellent Video. Thank you.

Hold your horses. Im a Cobol/Mainframe Developer for 20 years and worked on and Off as a Freelancer, but never worked on a fulltime position... Why? Because they are on average 5 Open positions per year in my country with 85 million inhabitants. So, its Not a Problem of know how, its a Problem of supply and demand.

7:18 Fun fact: the stack of binders next to Margaret Hamilton, the "rope mother", is not "the software", it is several versions of the software. I assume one binder was one version of the software, that is the listing of the 69000 bytes of the final version for AGC. If I remember correctly, to stack the binders was the photographers idea, to make it more impressive.

So the problem is that much of the coding done is using magical number without any comments. Ah, that makes sense, I assume it is not impossible to learn cobolt, but looking at the code and needing to take educated guesses on what does what, it is a massive headache, the older the system is, the more quick fixes you see that makes things even more complicated and no comments so even more magical numbers. I assume there are some old heads around that knowes cobolt. But the older a programming language is, the more pain is it to use on moden hardware. Due to its limited nature.

once i lied i dont know COBOL

Awesome 👌🏻

I still have my COBOL text book from back in the day. I agree with the comments that if you can learn Python your can learn COBOL. Indeed I wish programmers would back themselves more, and employers back their programmers. If you can PROGRAM, if you know something about structure and boolean logic, learning another language is not impossible. There will be some challenges. Most of my working life, and all of my training, was in languages that had no scoping of variables. Or, if you prefer, everything is globally scoped. So scoping was something I had to get my mind around, but now I've done that. I'm working in a situation now like the one described here. Lots of old code, no documentation. But it could have been a whole lot easier if programmers just commented their code so you know what the intent of it is.

No-code has its place, but let’s be real, it’s not for every situation or skill level. People resist it because change feels like a threat to their expertise or jobs. I’ve also tried and failed, but failing doesn’t mean no-code is useless. The world evolves, and tools like these make tech accessible to more people, even if they aren’t developers. Sure, it won’t make everyone a Google engineer, but it can help launch a functional product or idea quickly. The trick is knowing its limits and when to call in the experts.

17:55. There is a detailed explanation in wiki covering the actual cause. As said, it was not a software or pilot error. However, it was a procedural error which caused two different overflows. en.wikipedia.org/wiki/Apollo_Guidance_Computer#:~:text=1201%20and%201202%20program%20alarms,-DSKY%20and%20Buzz&text=PGNCS%20generated%20unanticipated%20warnings%20during,alarm%20was%20a%20soft%20restart.

13:30. The reference to NOUNS and VERBS, apart from the Shakespeare quote, is actually the manual input to the DSKY keypad. The keypad you displayed at 12:09 you will see these button names. VERBS indicated actions to be performed, NOUNS referred to specific data or items that actions were applied to.

in your dreams

The Lector, mentioned in early James Bond films, I would imagine.

MERN won't get you hired...

Assembly is a nightmare of a language. Remember that early CPU's couldn't do multiplication or division natively beyond bit shifting. Try doing high-level calculations on what is essentially an abacus.

Thanks for the nostalgic COBOL

I am 56 year young, Once I started to develop a software to convert cobol code into other language during Y2K Got success too but than whole project became useless due to no demand for it I am still developing ERP in .net, has knowledge of flutter , react-remix , python, jquery, tailwind, bootstrap
