اسلایدها و اطلاعات بیشتر:
پروژه آپولو اولین سیستم پرواز بود که با یک رایانه دیجیتالی با هدف کلی در هسته خود مستقر شد. رایانه راهنمایی آپولو (AGC). این یک پروژه تحقیقاتی کامل بود: هیچ رایانه ای دیجیتال بیش از چند ساعت پیاپی اجرا نشده بود ، تکنیک های پیشرفته برنامه نویسی ناشناخته بود و رابط انسان / کامپیوتر برای جلب توجه فضانوردان مشروطه با دخالت دستگاه در عملیات پرواز ساخته شده بود.
در این گفتگو ، من به تاريخچه AGC خواهم پرداخت ، در مورد پيشرفت پروژه آپولو ، درباره طرح اوليه و سير تحول اين طرح بحث خواهم کرد. ما به معماری دستگاه عمیق می پردازیم و متذکر می شویم که ادغام تنگ با یک وسیله نقلیه مخصوص ، رفتاری فوق العاده پیشرفته از یک ماشین ابتدایی را پذیرفته است. در ادامه ما رابط انسان / کامپیوتر برای AGC ، چگونگی نقش هواپیماهای فضانورد نقش کامپیوتر و برعكس آن بحث خواهیم كرد. از نمونه های انگیزه در پروازهای انتخابی آپولو استفاده می شود.
در طول این دوره ، ما به یادگیری درسهایی که از تجربه مهندسی AGC و چگونگی تطبیق این درس ها با سیستم های رایانه ای مدرن در استقرارهای مهم برای ماموریت بپردازیم ، توجه خواهیم کرد.
اهداف گفتگو:
هدف از این گفتگو توصیف ابزار و روشهای آنچه اکنون می نامیم مهندسی نرم افزار در زمان واقعی جاسازی شده در یک زمینه جذاب و تاریخی است. بسیاری از تکنیک هایی که اکنون در کتاب های درسی کاملاً ارائه شده است ، توسط مهندسانی که روی کامپیوتر Apollo Guidance کار می کنند ، در خدمت پرواز با ایمن و بازیابی مردان از ماه ، در پرواز اختراع شده اند. مخاطب برای یادگیری در نظر گرفته شده است:
* اکتشاف سیستماتیک حوزه های مشکل اساسی
* تکنیک های برنامه نویسی جاسازی شده برای رایانه های کوچک
* رویکردهای تاریخی برای ماشینهای محاسباتی
* تحقیقات دم بلند که به پرواز موفقیت آمیز در فضا به ماه رسید
مخاطب هدف:
– مهندسین نرم افزار عمومی ، افرادی که علاقه مند به پرواز در فضا و مهندسان سیستم های حساس هستند ، اگر همه مطابق برنامه پیش بروند ، باید از صحبت کردن بسیار لذت ببرند.
درباره برایان
برایان ال Troutwine یک مهندس نرم افزار با تمرکز بر تحمل به خطا و سیستم های بحرانی در زمان واقعی است. او به طور گسترده در ارلنگ کار می کند و مهندس ارشد با AdRoll در پروژه مناقصه در زمان واقعی است. برایان مانند چیزهایی است که با شکست روبرو می شوند.

I see a lot of negative comments about the Brian's lecture, but we should remember that he is a programmer not an aerospace engineer, so I did not tune in to learn about orbital dynamics, hardware design, etc. What he knew about and explained very well the 'Priority Tasked Scheduling' software executive for the AGC and how it functioned. In his area of expertise I think he did a good job of explaining the software design and capabilities of the AGC, as well as limitations.
37:04 Execute Order 66!!
41:42 Isaac Newton: "If I have seen further it is only by standing on the shoulders of giants."
Would have been funnier if he said Arse
I really wanted to watch this. But that funny fabric that makes that squeaky-squishy sound every time he moves his arms…..I just can't take it anymore. Adios, made it to 8:58.
How charming
This guy knows very little. So many factual errors as people have described below. It's not that he doesn't give enough information, it's that he says A when the fact is actually B. It's hard to listen to because you don't what else he is saying is wrong.
Annoyingly, the sound volume keeps reducing throughout the recording. Otherwise, it's interesting and informative.
When talking about Apollo .. Use Pounds & Miles..The way it was done ?
Stupid letterbox. Didn't need that up the WHOLE damn lecture. Made the pics too small. Derp
Is anybody going to ask where this magical guidance computer ended up? Smithsonian Museum maybe? No! Johnson space flight center? No! JPL? No! It just vanished without trace along with all the data, and yet just look how many experts there are on it, Houston! We have a problem!
It's a shame that I can't hear the speaker. A little post production really makes a difference.
I don't mind you using my DSKY for your lecture, pleased to see you chose it over all others,

My hats off to all the guys that eat this stuff up. I failed intermediate Algebra, so I appreciate that we have some real brains in this country.
Littered with glaring factual errors and claims.
Doubt they regretted saving 50 lbs, you can recover from a gimbal lock, you can't recover from not having enough air, or food, or a nice strong parachute on way back. 50 lbs is an enormous weight when we talk spacecraft. Lets not forget there are a bunch of other system besides the guidance computer, so if they could shave 25% weight from a system that was a 3rd redundancy already and use that weight somewhere else where it was mission critical, why not ?
In Margaret Hamilton's own words: https://www.youtube.com/watch?v=ZbVOF0Uk5lU
There are people that are currently alive that are not on this planet. ISS
good video. even though its old. Good job
WRONG, what about the Nazi base on the Moon ? There are humans alive currently on the Moon !
Ummmmmmm the international space station means people do live off the Earth right now……
well at least we can say for sure no ones going to the moon any time soon.
We 'sit inside a great project' ? This guy is dangerous.
I love his enthusiasm. He has a genuine love for the subject, and I enjoyed learning from him. Thanks for sharing!
I belve it was liquid FREOn not Xenon ? I may be wrong..
Stellar audio. Really. Absolutely top-notch quality. Give the sound guy an Oscar for his work.
AGC is the best computer I think
0:36 "This is the earth. This is our planet. This is where all us are, presently. There are no people that are alive, that are not on this planet."
FALSE
Astronauts Scott Kelly, Timothy Kopra, and Tim Peake (UK), along with Cosmonauts Mikhail Korniyenko, Sergey Volkov and Yuri Malenchenko were all alive, and were NOT on this planet during this conference in early November of 2015. They were members Expedition 46 in low earth orbit aboard the International Space Station.
I came here from a video breaking down the many many problems apollo had with its data transfer.
This is a lie & all you morons eat it up, look at what you swear has happened NOTHING works!!!!!
never been back eh, the astro-NOTs now days will jump at the chance to say we CANT get to the moon today.
They must of lost the giant model they built.
LOL fuck you guys you are retarded
An American starting & ending his speech with obscenities. Super professional.
