Good morning.
Good morning.
morning.
So twice in a row now i've gone into the ground room.
hey I did that yesterday. Also what's happening.
what's happening just in general or.
yeah what's happening in DR happening, you know.
Okay. Well, so happy Thursday for. One thing, first of all, for I forget. and Canada is one step closer to qualifying for the World Cup in Qatar.
What we are.
So. we're in the octagon so I. and i'm a bit new to. The ins and outs of the World Cup qualifying system, but so in our. area that goes. It covers the Americas, basically, I guess. So, as the first round. That decided eight teams and now. we're in amongst the teams were. Which is called the octagon. We play each team twice home and home. And so the matches are done in groups of three I think so there's four windows. And we just completed a third of the fourth one third of fourth for windows. And so far we're on top of the standings in the octagon was 25 points so you get three points for a win. 1.4 hundred and zero points for a loss, but. So we would be the United States, the other day. Thank. You build a beat El Salvador last night so. I remember when Canada first qualified for the World Cup back in 1986 and I thought that was. exciting. And I didn't expect that it would be. 30 close to 40 years before they might qualify again.
But.
it's not done yet, but. So the top three finishers. In this octagon will advance to Qatar. And the fourth place team. has to play a playoff with another region. And so, as I understand it, Canada can finish no lower than fourth now. So. Keep winning then. get one or two more wins anyway, then you have a lock on one of the top three spots. But. Not not to put the cart before the horse, so to speak. So those it's good news. Something to. Somebody doesn't have quite as much. Well, something with good vibes instead of other kinds of vibes a lots of stories in the news are giving off I guess. anyone else have something to mention.
I got one for us.
Okay.
Go ahead.
i'll see your likened the fight between intel's Z ons and andy's epic processors like a knife fight and a phone booth.
that's quite as quite a vivid picture.
All right.
So. Do you want to. Post, the link to that story in the chat.
I already did. Okay, great.
Alright, so. let's do our attendance. share my screen. Sorry. That was a link I posted into our meeting plan. And I didn't copy.
I got it.
yeah thanks. I had copied and just pressing the command V to paste it, as you said that.
No worries.
And can be done. So I didn't set up an activity. Yet for. Assessing. The covert data. or searching for resources so that we might. have some clarity for ourselves about. The efficacy of vaccines and so forth. And I did find. So we can maybe discuss a little bit today. So I did find a Twitter thread. written by Dr Alex long who's. Sometimes on the news that he's a physician at the general hospital, I think. And so. we'll just put that up here. So. we're here we go. So I don't know if this thread is. A common feature and Twitter. So I. i've given up on Twitter some years ago. and partly because. I did not. True, for me, I don't I didn't understand and maybe I wouldn't still understand the intricacies of the mental model that's. The basis for the service. Because I was on Twitter some you a few years ago let's see. Maybe five. Maybe it was 2014 I had an event, I want to promote. It did a video, and I was tweeting to everybody. Well, details of the event in the video. But then I had my. Account locked because I was flagged for spamming. And the reason I was that doing that was because. I was thinking of. So my my mental model, the way I thought about service was. It being like email, so I would. I was sending essentially the same tweet but I was addressing the different people. Including different. ideas on the. we're sending it to different are mentioning different. Twitter handles with each tweet. So this got me into trouble quite quickly. And I begged and pleaded that I said I really want to get the news out about this event was happening that day and. So eventually I got reinstated but. For me that's not the. i've just decided to leave it alone I don't know what what experience you've had with Twitter. Okay, to encourage. Some discussion here and that's. All. Do you like Twitter. say what you think. So i'm doing alternatives here So what do you think of Twitter using a lot and I like it use it event and it's okay. tried. Okay. So I have a ball ready here. About Twitter. So i'm giving you four. choices. or i've written rose sort of outlined what the choices and then, if none of those four fit your experience he can write other so i'll start the whiteboard You can write in the chat or type on the whiteboard if you'd like to add your. And they're feeling about Twitter. So I turned off names for annotations on the whiteboard if you want to. To get a few more. seconds of it gets replies. Okay, well, we had some pretty good participation so and. Okay. So is that VI VI peace. Or is that a w I can't. it's a little bit hard I think that's to these. Let me go back. Right. So anyway. I want to. engage a little bit about Twitter here because I want to mention. interfaces. So the end of them is firstly. Put a school Grad. And then slash one. And then here's slash to. slash 3456789 and.
1112 1314 1516 1718 1920 2122 2324.
And then the last one is 25 but it's not number is 25 just says end. So 240 characters a message. Times 25 messages, so that. let's see. It seems to me like 6000 characters. are available in this forum. So is it easy to. To get from the start. To the end. And what happens if we. get a. get a tweet one of the tweets from a metal can we. get to the. front of the threads. and read all the way through or. Is that. difficult to do. So it's been the clements passage and posted a bunch of times in the chat. bunch of times by me and a bunch by other people so. So I don't have the link here, so another thing in the news. Because this is from last week or last weekend there was an arrest of somebody. was making. Making guns from 3D printed parts.
This is actually happened a few times and back when the 3D participants came out somebody printed a gun, not just in the state, but I think in Canada.
well. There was. Like I don't have the person's name off the top my head, but he was he was formerly the head of Defense distributed. The company in the States. that's interested in promoting a different. Their own version of. public interest. yeah so it's not new. But from the pictures in the story and i'll post, the link. The story. It looks like they're good more advanced than what was first 3D printed guns. and Then what they've looked like a few years ago. The one that made the news some years ago, was a single shot gun. So you could put one bullet in it and. And discharge it. All.
we're just posting more links to other articles, also involving 3D printed guns. That just you know better, the chatters.
yeah, so I think one's about to sketch from the same story that i'm referring to. So in talking about the public interest. As a general concept that maybe we think. It doesn't need to be defined, because they're already. Has a sense of it. But in this case. So the people at Defense distributed were. Originally. actively promoting a different. idea of public interest and it's common. So that's why I think it's important to. To think critically about statements like well what is people say well it's not it's in the public interest or it's not in the public interest, what do we mean when we say that.
Sorry So can I get you just to repeat that question I kind of missed out on the last part of that.
well. I suggested. That. You know people talking with the public interest in a vague way because. Maybe it's easier to deal with, if you don't define it to carefully.
Well, definitely because ignorance is bliss.
mm hmm.
So I I was associated with a startup company in Vancouver some years ago and they talked about their intellectual property plant portfolio. Which is very impressive but. The they had submitted a number of patent applications. But they had not yet got point of. adjudication so. They could say. They had all this intellectual property. But it was only an application form and hadn't been tested. By the patent. By the Patent Office or patent offices different countries. So this is a little bit the same idea. You can talk about public interest. And if we don't. Define too closely, then you know we can define we can continue on. And everybody can talk about it. and Everyone be happy that they're talking about public interest, even though they might have really different ideas about what that is in practice. Does that makes sense.
Definitely.
So. it's a question about. Reading the that reference book The blown to bits second edition. And some other things. So. it's a. Long to this book is, it is a good. good thing to. Introduce many aspects of what we're talking about in class. But also links on the web. That I find. And that you, you may find so. As we find. links to the things that are happening. In the news each day. are presently you know. Our contemporary with our class here. Then we can collect, we can share them. In class and we can evaluate them. as well. So I know that's not necessarily. A common you'd like me to say. reads these pages for this topic and. There will be a question on the final exam. So my goal for the class is to. encourage you to think critically about what's going on. In a world today, and how. And how our reliance on computers in our information society creates both risks and rewards. And how do we. As computer professionals or future computer professionals. Think about these challenges. How should we behave. What what is ethical behavior for us. And for other professionals.
that's such a hard thing to even think about answering right, because how many variables you got to think about how many different laws and things you got to think about inviting not only laws, but the. ideas of people and how they.
Can.
Think of themselves and how they should be treated and everything to you have to take into account.
yeah. So I think there's lots of issues. That, I think it's also. Say it's. in society, when software so many things are dependent on computer technology. That it's incumbent upon. The computer professionals. So that means. The people who write code. and manage information technology systems. For them to have conversations about. The impact of their work. And the. And the kinds of principles that can guide the behavior so that. Are you said, this is the use of technology in the world it's. is held to a high standard I guess. So. The questions may be difficult. They think we can come to an answer, we can work through answers. And I think that conversation is important. And it may not be that we have. We come up with the best answer to begin with.
No.
But we can come up with an answer and refine it over time. As we get more data as we. get more understanding of the impacts. Of the choices we make. So it makes sense. Okay, so I was flipping through back to here because I put a couple video links here in last week's. Show there's one from don Norman and one from David Kelly. So. I have a few laws here. Are proposed laws they're not really. laws like. Was and during the physical world, for example, but. So they proposed by there's. Three interfaces. proposed by Jeff raskin who's one of the designers of the apple MacIntosh back in 1984 we did some other things as well, so he wrote a book called the human interface, which is a nice. what's a nice book to read. Anyway, he said. So talking about the human interface, he said, the dinner and interfaces you may, if it is responsive to human needs, and considering of human frailties. So then, here are the two laws and he. mentioned. A computer should not harm your work or through an action allow your work to come to harm. So that's similar to. asimov's three was. and rights. And a second law that he proposes a computer shall not waste your time or require you to do want. You to do more work than a strictly necessary. So I would sit. Why didn't get it. Has anyone heard about flight for a one. This is, many years ago. We crashed into the Everglades. in Florida.
I can't say i've heard of it, Sir okay.
So. There, there are other video and we used to it was an episode of made a which was show produced in Canada. But this is a bit more of a concise. it's not a reenactment but it's a description of what happened, so the title is how a broken $5 ball costs this message into crash in Miami.
say a $5 bald.
So the story was basically. The there's a. Clear night, but there is no moon, so it was very dark. And pilots were. preparing to bring the flight into Miami. And they put the landing gear down. But there was no way to confirm. The bulb on the in the cockpit that in that said yes, the landing gear is down. was burnt out so they didn't know whether it was burnt out or whether the landing gear wasn't down. So. They had set. relatively new autopilot system into. and set up the autopilot. And then. The pilot the copilot work. very hard to get the light bulb. Out of to change the light bulb in the control panel. see if that was the reason, so they couldn't get it out and even sent. The flight engineer i've moved his his title down below the deck to see whether he could see the. front, the landing gear down on the nose. and It was so dark and there were no lights. available for him to. To see whether the gear was down he couldn't report positively or negatively about the gear status, so you went back up to the cockpit. And they were continuing to work with a light bulb and then. What happened was in there working to change the light bulb they inadvertently shut off the autopilot. And because they were so engaged in. The light bulb for the landing gear they didn't hear the warnings. Until there was a very loud warning that they were below 1000 feet, I think, maybe 500 feet.
It kicks another thousand yeah.
yeah.
So. At that point he heard it. and It took them some some time to understand that the autopilot had gone off because it's a very dark night out and so that it's very hard to see what was going on. So, by the time they realize. That they were had shut off the iPod and they were. few hundred feet above the Everglades it was too late to to correct. To make any corrections in the plane crash there. So. My connection of late for one with. A computer should not waste your time or require you to do more to do more work than a strictly necessary. Is that. The system. The amount of work strictly necessary for pilots flying. A commercial airliner. Is not just to sit there. and make sure the lights Come on, when they're supposed to and. Everything else they need to be engaged. In that in what's going on with the. With the airplane at all times. So. From an ethical perspective. The amount of work that strictly necessary this theme relates to the amount required. To keep someone engaged. In the details of the. Of the flight. In this case. What do you think about that.
Man looking at pictures of this plane crash or this incident, I am surprised that 60 plus people actually lived through this out of 167 people.
Well, I guess. Maybe the water. made it a bit more soft landing than it.
would have otherwise been crushed on dry land.
Nobody was in the swamp.
All Okay, I see what you're saying yeah the pictures don't make it David any texture like that. So total of 75 people survived out of hundred and 6367 were passengers and 10 hour flight attendants yeah.
So they're also been some stories about, because this is an l 1011. o'clock EVAL 1011 which is kind of interesting design it's kind of. The third engine and the tail. They sell which parts from from the crash, and they use them another all 10th 11th and. There were some reports of ghost sightings. On those planes that got some spare parts. So that that's not the topic of our discussion today. But, so this is not maybe so different than your reports of what happened when those Boeing 737 max's. crashed. in the sense that. Well, in this flag for one example was. The crew may be relying too much on the. idea of the. flight control system or the automatic pilot. But in the 737 Max it was the pilot. Trying to actively disengaged. Some software that was. Making the wrong. interpreted. Interpretation of data that was fed in from. One one of the sensors on the plane. So they were both. Examples of. The interaction between people in computers. And they're likely some others as well. So there are a couple other examples, maybe i'll just mention those. One One example is with the Apollo 13 flight. Where the accident. occurred on the way to the moon. And the success. It was success successful flight because. The astronauts are able to make it back to earth, but they didn't. get to complete the Lunar landing. And the interface issue there was. The carbon monoxide. scrubbers in the command module and the Lunar lander. So they both had systems. They worked fine on their own, but the filters were not interchangeable between the two, so when. It became necessary to spend. extra time with more people. In the spacecraft they needed more capacity. to clean the air. And they found that they knew they had enough filters, but. They couldn't use all the filters in. In the command module where they were located. So. The people on the ground, had to develop a strat. A method based on what. materials they had on board. and involve duct tape. that's maybe no surprise. But the idea of. So they were able to create a system or. A method for. Attaching. or using. All the filters they had. And the question for design. it's maybe. Related to how do we deal with. How do we. flag something where we have two different. We have a square filter and around filter. And is that an important difference and. You know, because sometimes we might be in a situation where we need to put the square. filter in the round hole or vice versa. And the third Another example is a third 25 has anyone heard of that yeah. Okay. So therapy 25 was a radio therapy. machine. It was built. It was marketed by the Atomic Energy Canada limited. believe in the 70s, or 80s, there was a partnership with a French firm. And there were some models that preceded this one with the preceding models. Out of mechanical interlock system. That would prevent. lethal dose is being given to. The patient so. So the development of the software began. On the models that had the mechanical interlock. And the. Implementation of the designers and implementation of the software system. understood that their software is working correctly on those earlier models, but in fact. The software. Is not. Working perfectly in all cases, but the mechanically interlocks prevented. overdoses of radiation to the patients. So. When the. came around and they remove mechanical interlocks. With the. False understanding that the software was correct. And there were a number of deaths. related to the system. And so. arts. So there are a number of issues with the design of the software. And the test.
and
So, for example, buffer overflows were part of the issue. So we weren't tested. testing to make sure the data conform to expectations, so they weren't. coding defensively per se. So in that case it was. The people behind before they released the third 25. They. saw what they wanted to see in the performance of the machine. And they didn't. They didn't independently verify the correctness of the software, so there has been a lot of positive recommendations to come out of that. But Those are some of the big examples where interfaces. And then, important. been important in the life and death situation. life and death situation. stick with that. Okay, so I don't want to start a. breakout room. With six minutes left. But let's. Go back to the whiteboard here. So i'll put this question to you how would you like to. activity. what's up Kevin see that all right. kind of hidden on my screen.
I can see it fairly good.
makes sense, so I could say we could do something like code vaccine triage like we did a search before. And maybe do that search on never platforms like being in Google and it kausea. clients and duck duck go. Maybe those five. Where do we. Take a question. And then search results and then. We analyze whether or not those results are. helpful were reliable or the quality sources. So you can either and i've turned on anonymous annotation if you want to type on to the whiteboard or. or draw. or. Type into the chat window.
Are we putting this just in the chat in here or on the wiki.
singing of chatting now, so I can set it up. In your courses. But if it's if anyone has any thoughts. leave them now because we're out of time. So. If there are people like to put things in the chat now as you leave. that's fine. And I will. put up an activity. For I guess for over the weekend. by noon today. Anyway, thank you for today.
I just have a question can you answer this question as a meeting response or.
well. i'd rather you didn't. Well, you can but i'd also like. Your feedback more quickly than midnight today. So if. If you can answer it. now and then. use that answers. say the same kind of thing in your response that would be a fine.
Okay, thank you.
can say, maybe what I, like most like to know more about.
His.
so on and so forth.
All related to happen and have a good weekend.
thanks you too.
I just had a question regarding to the project proposal is there, like a specific format that you want to just introduce like our project and the project proposal for like you have to write an essay for the project proposal.
So i'm just looking for a pair some some paragraphs one or two pages with those headings that i've indicated.
sounds good, and then, basically, can I use like the same headings in the project or should be something different. If I write another introduction in the project proposal, can I just use the same. Paragraph in the project.
well. yeah I guess you might have a little bit of overlap, but I wouldn't think you would use the same text verbatim because you want, you will have developed it further, by the time you submit your project sounds good.
Thank you.
So. See how. i'm not sure offhand whether. Those headings are appropriate for the deliverable. So, I guess, I would say, maybe see how things work out as you during your research behind. And we can talk more about that. As we get closer to. So. I would say, focus on the proposal part now. and across an expiration to come to it. Once you get an idea of what more. And more firm idea what you're doing.
OK.
For the proposed for the project deliverable.
sounds good Thank you so much, I have a good day after.
thanks you too.
Yes, i'm.
Sorry, Sir, I do put the attendance the password for the attendance and when I tried to put it is now it didn't along, but I was present.
yeah okay. Second here. Thanks why fix it right now.
hey.
Okay. If any of you are still left. we'll see you on Tuesday, have a good weekend take care. Yes, i'm.
Sorry, Sir, I, how can I might marked my attendance.
fix this year.
I didn't see it sorry you go.
No, no, I have to change it.
You.
know. A couple minutes. Thanks everyone bye Thank you, Sir.

is it about Scott Moe
I only actually use Twitter when I get linked from another source!
never use it
Something Else: I have never used twitter and almost never look at it.
Never tried it. Never use it unless someone shows me it.
Never used it
I only used it to see the covid updates easier
Something Else: Use it a lot but don't like it.
Something else: I use it all the time and hate it. Why do I keep going back oh god
It's a useful tool that almost always goes misused.
I made an account to claim my name. I never use twitter.
I look at stuff but don't post, only sometimes though
I think its a good place for people to have discussions, I usually read to get more insight on topics
I use twitter because its more quick then rest of the social media
mostly I used to read others tweets, but tweeted only a few times mydelf
never use it, but my friends screenshot twitter post and post it on facebook/instagram
I have an account but I rarely go on the app
Never tweeted anything. Solely look at xrpl trustlines
Good way to contact customer support/service for various stores/corporations
Just read through the tweets but never tweet
I think twitter is great depending on what space of it you're on, as with most social media
I use it a lot, just to read sports and other daily news. Never posted anything.
Sometimes I think I'm being forced to use it as all the VVIPS post there all the time
Never tried it!
Double v
Not very often used used。 After Trump, it is used even less

Thank you!
Both of these activities sound interesting but I think I would prefer Searching for an answer to a question. across different search engines.
^
Either way it sounds interesting
I'm good with either
I would like to do a search across multiple engines and maybe even with vpn on and off or adblock on and off
^
In my opinion, it is quite important to analyze the source for the results i.e., how were the results obtained?
Coming up with results and evaluating their quality since that is the most important part of assessing data.
Thanks for the lecture!
Thank you
thank you
Both these methods sound compelling to try. But if I have to choose one, I would go searching across different search engines and try it with different restrictions such as w/o location, doing VPN etc.
I'm just letting you know that response to meeting 8 isn't showing.
Response now fixed

Responses

The most important thing that I encountered:

The most important thing i learned is that an interface is humane if is responsive to human needs and considerate of human frailties.
the most imporant thing i learned was about the purpose of interfaces and how a flawed design can cause harm which lines up perfectly with what we learn in CS 215.
Most important thing about today was learning about flight 401
I learned how other people view twitter. For the most part I think it's a cesspool of complaining, but it is also a very important tool in communication for things like revolutions in many countries.
How can I minimize my risk of contracting and transmitting COVID? Searching from 3 or more search engines.? The most helpful search engine was Qwant
interfaces are important to flight.
The way we design systems is really important. Today we discussed how interfaces often are life and death with reference to feric 125m, flight 401, and apollo 13. Here all of them caused unnessesary danger. Apollo 13 did this by not having interchangable CO2 scrubbers thereby causing unnessesary work. Flight 401 didn't have adaquate sensors so when a lightbulb failed they had to put a lot of effort into sensing if the landing gears were down. The autopilot should have had warnings about being disengage
Today I learned the impact of relying on Computing in our society with examples of Flight 401 accident which killed 101 passengers, 737 Max Fault Sensors which killed 346 passengers, and Apollo crash 3 crew members.
An interface is humane if it is responsive to human needs and considerate of human frailties. A computer shall not harm your work or, through inaction, allow your work to come to harm. A computer is created to help people to do their work.
The thing I would like to think know more about from today’s meeting is why humankind struggles hard when automatic fails. As Jef Raskin says, “A computer shall not harm your work or, through inaction, allow your work to come to harm” and “An interface is humane if it is responsive to human needs and considerate of human and machine frailties”. A computer professional must have an understanding of relevant information on how both human and machines operations.
I learned a lot about how we can relate current news and events to the course and course content. This will help me with my project and my blog posts because it will help me easier identify topics I could cover in these assignments.
The Laws of Interface by Jef Raskin taught me how computer professionals should be accountable for their every single action. They should not allow a computer to affect their work. Computer professionals should check their code and software thoroughly before they work with them in the field.
The most important thing I learned is that it is important to check that programs and make sure they take into account what the people who use them need to be responsible for. In some of the examples stated in class, there where issues where people were to reliant on programs and there were situations where programs did not work as intended. It is important that people know the capabilities and limitations of programs.
We investigated what the students thought of Twitter. I personally have a lot of fake news on Twitter and I don't trust Twitter.
It's hard to imagine how just a small a small detail can lead to a big event, like the broken lightbulb that leads to the crash of flight 401
That simple design choices in technology can have an impact on many lives (easily change a burnt-out lightbulb in planes, safety switches in Therac-25). They need to be well tested and user-friendly (as well as other qualities) in order to prevent damage to people, environment, and businesses.
From an ethical perspective, the connection of Flight 401 incident with the Jef Raskin's third law of interfaces i.e., a computer shall not waste your time or require you to do more work than is strictly necessary was that the pilots should have been engaged at all times and not shouldn't have just relied on the auto-pilot. The pilots relying too much on the auto pilot or flight control system caused the flight to crash which could have been avoided if the pilots had been engaged at all times.
The most important thing I learned today is that that when we are at the work environment we need to relay information correctly and engage in our work. I also learned that information from the news is helpful for the class. We discussed In the class about the Olympics and the world cup. The impact of Covid-19 and that Saskatchewan is going to lift covid restrictions.
I have learned about interface aspiration and their examples, I wasn't aware of the incident which happened in the ghosts of flight 401 as the flights didn't have adequate sensors and when the light bulb failed, pilot has to put a lot of efforts sensing if the landing gear were down, which unfortunately caused the lives of 101 people and also the Apollo 13 accident..
computers have to be designed very carefully to avoid tragedies such as flight 401
I learned that an interface is humane if it is responsive to human needs and considerate of human frailties. That is an equipment that is built to perform a particular function or activity has instructions to respond to the various needs its users may have and in the process of carrying out its instructions is able to interrupt program flow if a its users could come into any potential harm; These kinds of interfaces are considered humane. The case of flight 401 exemplifies an interface that is not humane be
In today's lecture, we have discussed about the twitter's post and we had a poll of how many are aware of twitter what it is actually and how many of us not using the app. Later on, we had story of Ghost of the flight 401, which was explained by Dr. Hepting in class.
The thing about twitter especially the poll got my attention towards finding more knowledge about this subject.
The most important thing i learned from today's lecture is about the current news about the world cup qualifying and a man from saskatchewan from weyburn is facing charges after rcmp seizes firearms. Then discussed the question about how to prevent covid-19 infections and have to submit results from various search engines. on how we can prevent covid-19 infections. The most interesting thing i came to know about is the ghost of the flight 401 how sensor failure led to very bad result. then the discussion on
Today we looked at professor's twitter and how people use twitter to share their opinions
Today, we talked about the ghosts of flight 401. The flight's lightbulb stopped working and then, pilots spent a lot of time trying to fix it. While fixing it they set the plane on autopilot mode which at that time was newly made available. It was in its developing years, so it was not well developed like nowadays. While repairing the lightbulb, the pilots accidently turned off the auto pilot mode, which became responsible for the plane crash.
Twitter is so dangerous, even a leader like Moe can spread incorrect information. It is very urgent that our government establish a law when using social websites for influencers. How can we trust our leader when they posted nonsense Tweet?
I learned today that the ultimate goal of an interface is to enable the user of a computer system to understand the behavior of the machine and to be able to respond appropriately to the behavior of the machine (computer). So when we design the human-machine interface of a computer system, how should we imagine the behavior of the computer system? In the author's opinion, the metaphorical approach is very effective. The so-called metaphor is to see the computer system as an object with some kind of behavior
The Therac-25 story has really emphasized the importance of testing software created. While I do not agree that any ethical decisions were made, as it it very tough to have an understanding of the software, hardware and medical aspects of the Therac-25. I do think a critical error was made by the company in not completing enough testing.
Always go through the safety checklist before a flight.
The most important thing I learnt from today's lecture is that how covid had impacted in the technology sector. And I really wish to learn more about this in future lessons.
The most important thing I learnt is how detrimental a poor interface can be, and the impact we’ve seen it have. I’m interested to see what current interfaces that won’t be accepted years from now!
I thought the discussion about interfaces was pretty interesting.
Compared to duckduckgo, which only lists statistics according to country, bing and google have made a more intuitive statistical chart according to region, where bing also made a cumulative diagnosis chart to clearly show the growth rate and other factors
The online database can be protected by firewall and in the coid-19 time, people still can work online

The most difficult thing for me to understand:

Still Interface Aspiration is an unknown topic for me and didn't understood the concept of it in relation with the different events like "The Ghosts of Flight 401", "The Apollo 13 Accident" and "The Therac 25". Would like to know more about Interface relation with these in the next lecture as I didn't understood them in this lecture and is still most difficult thing for me to understand.
How do we plan out what we are building to include all potential use cases? Using Apollo 13 as an example; how do we know to think about situations where the air filter in one module should be compatible with the air filter in the other module?
The most difficult thing for me to understand in today’s class topic about the guy who was printing 3d guns. is that why would some people use internet to prompt the wrong version of public interest? Promoting guns and violence will harm many people and many innocents will be victims of any terror attacks caused by selling guns. Would the desire of earning money will make people to choose the incorrect decision to not caring about the safety and life of others? Selling things that protect others on interne

The thing about which I would most like to know more:

I would like to know more about what methods social media sites use to censor content, and what (if any) regulatory oversight is involved.
The thing from today's lecture that i would most like to know more about is how a $5 light bulb caused the crash of an airplane. Don't they have to check everything before takeoff? Did the light burn out during takeoff, when else would it have been on? Did the plane engineer not have a flashlight when he went to check under the plane to see if the landing gear was down? There was so many mistakes that could have been prevented.
W have learned about 3D printed guns in Saskatchewan and how they were obtained illegally. I would like to know more about how government is taking steps to prevent 3D guns from getting in the wrong hands. 3D guns are getting extremely easy to obtain nowadays. A person with a 3D printer and a few ingredients which could be bought from a store can easily print a 3D Gun. It is extremely easy to get a 3d printer hence, a 3d gun. But, I haven't heard of the law doing something out of the ordinary to prevent it
why do big comperations take most of our internet information
If you used three different search engines using the same search history, if you would then get similar search results to one another.
Today we have discuss interface Aspiration and its examples. The three examples we have discuss that are The Ghosts of Flight 401, The apollo 13 accident and the Therac 25. I would like to know more examples in this topic.
today's class was very interesting but I'm curious in how various websites present different results for the same subject.
Why doesn't the government or 3d printing software companies manage and track 3d printing activities? Someone could make a bomb or a gun using a 3d printer for malicious intent without anyone knowing.
how search engine connect multiple websites
Today's topic and discussion about the interface intrigued me. In contrast to other tools which often have limited uses, computers often have many uses that involve an open-ended dialogue between the user and the machine. The interaction between a human and a computer has been a vital area of research and I am interested to know more about this area of research. I am also eager to learn more about artificial intelligence and how it is amazing in terms of helping users have a better experience.
Interface errors! They seem like such a simple thing, yet they clearly have been missed in the past to cause dramatic problems. Is this something that should be taught more in Software Engineering classes, to ensure compatability with similar systems? Or should these largely be treated as freak accidents?
The thing which I would most like to know more about is how we can make sure these tech companies are programming in an ethical way. How can we make sure that the coders biases are not coded into the algorithm?
Since we talked about interface examples this class, I wanted to get to know more about interface risks and rewards regarding computing technology. And since we were discussing whether someone would rather search on different engines on COVID related news or evaluating the quality of their own answer, in my opinion, I would rather search for an answer on different search engines and maybe turn off recognizable filters (ie locations, vpn, etc) to fully credit the search and not have biased claims.
I would like to know how different search engines seek different access and information.
I would like to know more about other areas in which computing makes an impact on society, not just social media. Although I understand that social media is an incredibly prominent element to the impact, I wonder what else there is that we could be overlooking. What other areas do we have so much impact on as computer scientists?
I would like to know how humanity looks forward to the advancement of AI and technologies in general. The high expectations individuals have , the fears civilians have of loosing their job to AI's, the fear of being harmed by one and how acceptable everyone will be towards the future humanity is heading.
I would like to know more about how the 3 laws of technology came to be.
I would surely like to know more about the interface of different browsers and by today's poll i gotta know how everyone thinks about use of Twitter.
To answer today's question: I would rather come up with the results and evaluate the quality of those results. It is better than searching for an answer across different search engines. It is not guaranteed that those search engines will provide good results. The quality of results matter especially when acquiring data. Good quality data gives good quality analysis.
I would most like to know about risk regarding technology as well as how we can resolve it with different ways.
Is twitter more user friendly then the other social medias that we use?
Why does twitter’s method of posting an article or people’s ideas a thing. Twitter would have easily implemented a feature that could display an article in image format which also opens up the opportunity to include images in the article.
Todays meeting was very good. It all started with the discussion on latest news. After that we all talked about interface aspiration and also discussed some examples related to that such as about the ghost of flight 401, the Apollo 13 accident and also about Theravada 25. After that the meetings ends by discussing about next meeting topic.
I would like to know more about what safety systems are in place in essential code such as the auto-pilot on air planes. I would also like to know how these codes are examined and tested to ensure that they work and are deemed safe to use.
the number of search result of specific topic and its trendcy
The phrase an activity dealing with accessing data (about COVID-19) as I prefer to evaluating quality of results than searching in other search engines as per medical search/news search I would go to renowned organization ex for covid I would prefer
I'd like to hear more about the Jef Raskin quotes, they were pretty interesting to think about.
