Also, no setting integers to a value. Instead, we'll initialise it to 0 and use a bespoke for loop to increment it to the desired value, then we'll unroll that loop.
Not that there is anything wrong with your code, but this way you're expanding from 2 lines to 12 (+500%) instead of from 5 to 12 (+140%). Marketing will think you did 3,571428 times the work!
Cars have had computers in them since the mid 90s, to monitor things like engine performance, status conditions of different components, and much more. Then in the late 2000s we saw a rise in "infotainment" systems, with built in touch screens/ GPS etc. This has led to more complex systems such as Apple Carplay and Android Auto being included in modern cars. The third wave of automotive software is semi-autonomous driving features, such as computer assisted parking, automatic emergency braking, more intelligent cruise control, and, eventually, self driving. All of this adds up, and as long as everything runs fast enough then there's no reason for a company like Mercedes to go crazy optimizing everything.
Or they do an update the next you take it in for maintenance? And I'm sure more manufacturers will go the Tesla way and just push OTA patches and updates.
mnbvas ยท 16 points ยท Posted at 07:12:13 on August 9, 2016 ยท (Permalink)
I hope no OTA, considering their track record with security.
If Tesla can do it, it is not outside the realm of possibility a malicious entity can push an update to brick or otherwise fuck with your car's computer from anywhere in the world.
It's so, so easy to compromise. Plus- if an Apple update bricks my phone, it's annoying, but survivable. If Tesla bricks my car, that's a much bigger issue.
Remember: every change made to software carries with it risk, and no extent of testing can ever fully eliminate that risk. OTA car updates are just plain risky.
I can understand an argument based on malicious intent. The risk of a vendor software update bricking your car though, doesn't seems like anything nearly strong enough to outweigh the benefits.
They won't be pushing an update except when your car is stationary at home, so safety isn't a risk. If they did 'brick' your car, they would send someone out to fix or replace it, or provide a method to revert. Seems far more likely they updates prevent a bug from affecting you than they brick you car.
Safety is absolutely still a risk! Did they test the update on my car specifically? Did they test it under my driving conditions? Of course not. So how do they know it works for me? The can have a degree of confidence from their testing, but they cannot guarantee it. There's a risk, and we need to recognize that and give the user control of updates.
Beyond that: what if I don't want the update? How many times has a forced vendor update removed a feature you used? I've seen that happen all the time.
And you also underestimate the risk of malicious tampering. Think of how useful this would be for corporate espionage. If GM wanted to kill Tesla, they could do it for a few hundred grand, probably. Even if it cost millions, that's a steal!
amunak ยท 1 points ยท Posted at 21:40:46 on August 10, 2016 ยท (Permalink)
Not so easy with proper precautions (code signing, authentication, doing it only in repair shops under supervision and obviously when the car is stationary, not being used).
We're talking about OTA updates. But it's still so, so easy to compromise, on a number of levels. First off, you have internal attacks- developers or people who have access to the code who make unauthorized changes. Yes, code reviews provide a defense, but that requires ME as a user to have FAITH in a vendor's software development practices, and that's worrisome when we're talking about cars.
You have a number of external attacks built around compromising the signature validation process. This could happen through poor key management (a number of instances of keys being compromised have happened), through attacks against the keystore itself, and so on.
You've also got to worry about the network stack that powers the OTA updates. Why worry about compromising the key if I can trigger a buffer overrun and get arbitrary code execution? The very act of giving the car a network interface increases the surface area of attack so much it's ridiculous.
All of this assumes that auto manufacturers are using reasonable coding practices- and we already know they're not. Which model of car was it had bugs resulting from piles of global variables and spaghetti code? Was it the one that accelerated uncontrollably or the one that would shift into park while drivingโฆ I forget.

What I heard from people working in Automotive as Software Engineers: About 90% of the Software is Infotainment, 10% is actual hardware control and all those things.

A base pair in a genome is 2 bits of entropy, not a full line of code. Assuming an average line length of 60 (conservative, but many people (Google/PEP8) restrict to under 80), and we have 480 bytes on average per line. That's easily two orders of magnitude of discrepancy.
I'm really afraid to read that code. All my experience with Mechanical engineerings and their coding skills is horrible.
The car is probably mostly Matlab code badly converted to C, or still Matlab code running in Dspace, or it is coded directly in C and they haven't used any functions and specified every single situation.
All three options I have seen happen in Automotive on my university and they work with Mercedes.
I would be too. If it's healthy code, most of that will be tests considering the difficulty of updating after release.
Otherwise if it can receive over the air updates, it should be mostly tests and analytics.
I know nothing about the problem domain, but I do a lot of business critical software in a heavily regulated industry. Tests are most of the line count.
I once had a cross faculty team project working with arduino robots and my task was integrating every ones code. Most of my time was making functions and reducing the code from more than a thousand lines to around a hundred.
The mechanical engineerings had a habit if a part of code was needed again with small alterations to the parameters to copy those two to ten lines and alter them. Not a problem to have a single list of code, but it makes switch cases very unreadable.

Oh god, that makes me nervous. I've seen some seriously shit code in industry, but I really hoped the car industry would have better standards, given how lives will depend on it.
I can say that they have started in improving. But most senior engineers do it the way they did it 20 years ago and a lot of students that go in to automotive think coding standards are unnecessary evil.
The local truck manufacturer (quite a big one) has written out every situation the truck can be in. So a lot of lines of code could be reduced by simply implementing of functions and parameters. [Parafrasing a CS student that had worked for the company for his graduation project.]

Apply the "If it looks stupid but works it's not stupid" principle. In this case "If the statement is meaningless but people still buy it it's good advertisement".
If you are a professional in a field and looking at something "stupid but works" in your field, it is still probably stupid.
gandalfx ยท -1 points ยท Posted at 13:26:29 on August 9, 2016 ยท (Permalink)
That's the point. Whatever subject you are talking about the laypeople will always be the majority. In other words, we are simply not the target audience of that specific ad, but there will still be more than enough uninformed people who fall for it. Meanwhile we may very well be the target audience of other, equally stupid ads that rely on us not having a clue about a different subject.
Of course a smart person will generally doubt any ad based on the "more is always better" premise but I'd still assume that a vast amount of people are stupid enough to fall for it.
In the end it doesn't even matter if the ad is bullshit. You don't have to intellectually accept that the statement makes sense for your subconscience to be like "damn that looks smooth tho". As long as you spend time thinking about it, it stays in your mind and is effective. "Bad advertisement is better than no advertisement" and all that.
The problem is I always hear the phrase about stupidity in context of my own field, or in rare cases other fields I am familiar with. I don't hear it about welding or neurosurgery or knitting or anything else. I basically only hear it about programming. And it is always wrong in programming.
Also, I am well aware of how ads work. But the two phrases in your original post are not equivalent, because one of them is always wrong, and the other is just basic psychology.

How... What?
Languages allow this shit?
Programmers use this shit?
"mutable constants" are static variables which do not have immutability ensured by the language rules.
Most languages allow this. Take Java for instance, if you declare a private static field but do not make it final, it is mutable. Name it with UPPERCASE_WITH_UNDERSCORES and you get something that anyone reading the code that uses the identifier would assume to be a constant but is not.
Don't use any linters and it may go years unnoticed. Until a very clever guy decides to change something by changing the constant during runtime.

It's not IoT, there are a ton of computerised features that do a lot to add safety, performance, durability, etc. Automatic braking, assisted parking, monitoring condition and wear, etc.
Whilw I agree that Internet of Shit-devices still have a long way to go (think the automatic cat feeder that stopped because the servers were offline, or the home automation system that stopped working because the company that made it didn't support it anymore) that doesn't apply to cars.
Modern cars have a ton of safety features and driving assistance technologies that are slowly coming together to fully automate transport, and that can't happen in a purely mechanical car.

Why does a modern car need so many lines of code? Is it all the libraries of functions that allow the hardware to communicate with each other?
Chris2112 ยท 43 points ยท Posted at 02:12:01 on August 9, 2016 ยท (Permalink)
Cars have had computers in them since the mid 90s, to monitor things like engine performance, status conditions of different components, and much more. Then in the late 2000s we saw a rise in "infotainment" systems, with built in touch screens/ GPS etc. This has led to more complex systems such as Apple Carplay and Android Auto being included in modern cars. The third wave of automotive software is semi-autonomous driving features, such as computer assisted parking, automatic emergency braking, more intelligent cruise control, and, eventually, self driving. All of this adds up, and as long as everything runs fast enough then there's no reason for a company like Mercedes to go crazy optimizing everything.

remy_porter ยท 5 points ยท Posted at 20:06:07 on August 9, 2016 ยท (Permalink)
It's so, so easy to compromise. Plus- if an Apple update bricks my phone, it's annoying, but survivable. If Tesla bricks my car, that's a much bigger issue.
Remember: every change made to software carries with it risk, and no extent of testing can ever fully eliminate that risk. OTA car updates are just plain risky.
ColdFire75 ยท 4 points ยท Posted at 20:17:24 on August 9, 2016 ยท (Permalink)
I can understand an argument based on malicious intent. The risk of a vendor software update bricking your car though, doesn't seems like anything nearly strong enough to outweigh the benefits.
They won't be pushing an update except when your car is stationary at home, so safety isn't a risk. If they did 'brick' your car, they would send someone out to fix or replace it, or provide a method to revert. Seems far more likely they updates prevent a bug from affecting you than they brick you car.
remy_porter ยท 1 points ยท Posted at 22:15:50 on August 9, 2016 ยท (Permalink)
Safety is absolutely still a risk! Did they test the update on my car specifically? Did they test it under my driving conditions? Of course not. So how do they know it works for me? The can have a degree of confidence from their testing, but they cannot guarantee it. There's a risk, and we need to recognize that and give the user control of updates.
Beyond that: what if I don't want the update? How many times has a forced vendor update removed a feature you used? I've seen that happen all the time.
And you also underestimate the risk of malicious tampering. Think of how useful this would be for corporate espionage. If GM wanted to kill Tesla, they could do it for a few hundred grand, probably. Even if it cost millions, that's a steal!
amunak ยท 1 points ยท Posted at 21:40:46 on August 10, 2016 ยท (Permalink)
Not so easy with proper precautions (code signing, authentication, doing it only in repair shops under supervision and obviously when the car is stationary, not being used).
remy_porter ยท 2 points ยท Posted at 23:16:42 on August 10, 2016 ยท (Permalink)
We're talking about OTA updates. But it's still so, so easy to compromise, on a number of levels. First off, you have internal attacks- developers or people who have access to the code who make unauthorized changes. Yes, code reviews provide a defense, but that requires ME as a user to have FAITH in a vendor's software development practices, and that's worrisome when we're talking about cars.
You have a number of external attacks built around compromising the signature validation process. This could happen through poor key management (a number of instances of keys being compromised have happened), through attacks against the keystore itself, and so on.
You've also got to worry about the network stack that powers the OTA updates. Why worry about compromising the key if I can trigger a buffer overrun and get arbitrary code execution? The very act of giving the car a network interface increases the surface area of attack so much it's ridiculous.
All of this assumes that auto manufacturers are using reasonable coding practices- and we already know they're not. Which model of car was it had bugs resulting from piles of global variables and spaghetti code? Was it the one that accelerated uncontrollably or the one that would shift into park while drivingโฆ I forget.

A base pair in a genome is 2 bits of entropy, not a full line of code. Assuming an average line length of 60 (conservative, but many people (Google/PEP8) restrict to under 80), and we have 480 bytes on average per line. That's easily two orders of magnitude of discrepancy.

I'm really afraid to read that code. All my experience with Mechanical engineerings and their coding skills is horrible.
The car is probably mostly Matlab code badly converted to C, or still Matlab code running in Dspace, or it is coded directly in C and they haven't used any functions and specified every single situation.
All three options I have seen happen in Automotive on my university and they work with Mercedes.

I would be too. If it's healthy code, most of that will be tests considering the difficulty of updating after release.
Otherwise if it can receive over the air updates, it should be mostly tests and analytics.
I know nothing about the problem domain, but I do a lot of business critical software in a heavily regulated industry. Tests are most of the line count.

I once had a cross faculty team project working with arduino robots and my task was integrating every ones code. Most of my time was making functions and reducing the code from more than a thousand lines to around a hundred.
The mechanical engineerings had a habit if a part of code was needed again with small alterations to the parameters to copy those two to ten lines and alter them. Not a problem to have a single list of code, but it makes switch cases very unreadable.

I can say that they have started in improving. But most senior engineers do it the way they did it 20 years ago and a lot of students that go in to automotive think coding standards are unnecessary evil.
The local truck manufacturer (quite a big one) has written out every situation the truck can be in. So a lot of lines of code could be reduced by simply implementing of functions and parameters. [Parafrasing a CS student that had worked for the company for his graduation project.]

Meanwhile we may very well be the target audience of other, equally stupid ads that rely on us not having a clue about a different subject.
Of course a smart person will generally doubt any ad based on the "more is always better" premise but I'd still assume that a vast amount of people are stupid enough to fall for it.
In the end it doesn't even matter if the ad is bullshit. You don't have to intellectually accept that the statement makes sense for your subconscience to be like "damn that looks smooth tho". As long as you spend time thinking about it, it stays in your mind and is effective. "Bad advertisement is better than no advertisement" and all that.

The problem is I always hear the phrase about stupidity in context of my own field, or in rare cases other fields I am familiar with. I don't hear it about welding or neurosurgery or knitting or anything else. I basically only hear it about programming. And it is always wrong in programming.

Also, I am well aware of how ads work. But the two phrases in your original post are not equivalent, because one of them is always wrong, and the other is just basic psychology.

When you have no idea what goes into coding or just starting out the number of lines in a program might seem daunting.
You get farther along and realize you'll write 500-1000 lines for the most mundane shit in the world.
I bet they are counting debugging code that will either never run or is not even included in the final binary.
Also, any game today would easily hit that many lines of code.

Unreal 3, just the engine with zero gameplay elements is 2 million lines of code.
I agree that measuring it by lines of code is pretty meaningless, but it makes decent advertising if your target demographic is non-technical people.

Bask in this seat of only the finest subroutines, arduously built by shops overseas that claim to hire software developers. Feel its texture, made gentle and contiguous by a lack of DRY principles.
Or perhaps you would like to enjoy some functional soup? Choose from 3 never ending non contiguous flavors. Just as you think you know the flavor, you'll realize you don't!
If variety is your spirit song, we host a 24 hour buffet of global variables with non idiomatic name spacing for your delight and amusement.
A cornucopia unspoilt by any who've come before, which is why we didn't write any tests. Join Mercedes in a blissful orgy as we speed toward oblivion.

"global variables with non idiomatic name spacing for your delight and amusement." So much true. I will have nightmares about some of those "mutable constants" again.

mafagafogigante ยท 1 points ยท Posted at 22:10:16 on August 10, 2016 ยท (Permalink)
"mutable constants" are static variables which do not have immutability ensured by the language rules.
Most languages allow this. Take Java for instance, if you declare a private static field but do not make it final, it is mutable. Name it with UPPERCASE_WITH_UNDERSCORES and you get something that anyone reading the code that uses the identifier would assume to be a constant but is not.
Don't use any linters and it may go years unnoticed. Until a very clever guy decides to change something by changing the constant during runtime.

I imagine they are exaggerating and including tools and utilities they developed for designing the car. Think custom tuning/programming tools and whatnot for testing and tweaking configuration in test cars while they dial stuff in.

Kif managed to make that holodeck-esque simulation with only 4 million lines of BASIC, so imagine how many moons, water reflections, light refractions, and physics that thing must have!
What's that? It doesn't simulate another planet? That's okay, as long as... Wait it's just a car, it isn't even a self driving car with a smart AI that can run errands?

It's not IoT, there are a ton of computerised features that do a lot to add safety, performance, durability, etc. Automatic braking, assisted parking, monitoring condition and wear, etc.

Whilw I agree that Internet of Shit-devices still have a long way to go (think the automatic cat feeder that stopped because the servers were offline, or the home automation system that stopped working because the company that made it didn't support it anymore) that doesn't apply to cars.
Modern cars have a ton of safety features and driving assistance technologies that are slowly coming together to fully automate transport, and that can't happen in a purely mechanical car.
