Yeah, pigs don’t like to be corrected. Or made to look like they don’t know what they’re doing.
And they absolutely hate ever doing anything about bicycle theft in particular.
I reported my bike stolen in college and I got a call the next day that they had found it parked in front of a nearby church.
It was stolen on a Sunday. I guess someone didn’t want to be late to service.
What you’re entering the third act of your love story and you have to get to the church in time to break up the wedding and declare your love, what’s a little bike theft? The universe will take care of it.
Probably added the theft to the sins they were confessing that day as well.
God made them do it!
I have heard that very often. I wonder if bikes are harder to track down than other property for some reason.
They only care about property loss when it involves rich people.
Which proves that cops really DO actually do their jobs.
Because protecting the property of the rich is the exact core purpose of policing.
Technically it’s maintaining social order. So get back to work menials or be reported to the Enforcers for organized discontent.
Maintaining social order, especially in the form of violent repression against demonstrations, indirectly protects the rich’s properties, so all in a day’s work.
Given the number of times I’ve seen cops on police forums and r/protectandserve use terms like “bikefags”, I think it’s just the typical cop disgust of anything they perceive to be weak or effeminate.
As a gay cyclist I know I’m doing something right by pissing off cops without doing anything wrong
Thank you for you service o7
Yeah, I don’t get that. Bicycling requires strength and endurance. It exposes you to the elements. Why is sitting in a cushy car something some people think as being more macho? Is it that you’re in control of a heavier and more powerful machine?
Bicycling requires strength and endurance.
So does cleaning a house, but that’s “women’s work”.
Is it that you’re in control of a heavier and more powerful machine?
That’s it. You didn’t get it at first because made the mistake of associating manliness with things like patience, strength, hard work, endurance both of toil and hardship; all things that do make up ideals of manliness to normal people. But you need to approach it from the perspective of a wastrel, a weak, foolish, and lazy person who demands the respect and deference of being manly without putting in the hard work—something he has avoided all his life. He might praise hard work in abstract, but he has no discipline for it and doesn’t respect those who actually do it, he just considers them beneath him. To such a person, the defining aspect of manliness and machismo is mastery, mastery over others and their wills, and since mastery through work is a waste of time to him, he turns to shortcuts.
From there, it’s not hard to see where the thought process goes. Since strength is to him based on control and mastery, he picks something that gives him more command over the road in a direct and in-your-face way. The man who drives a lifted Ram 2500 can confront you by running you the fuck over. By contrast, in his opinion, cyclists are entitled jackasses in miniscule booty shorts who can only confront you on the road by screaming “CRITICAL MASS! FUCKING CAGER!” and throwing sparkplugs at your windows. The difference in power dynamic is proof enough to our friend of who the “real man” is.
To take the mentality to its conclusion, the easiest way to gain mastery in general is through authority, and the easiest way to get that, even easier than joining a gang, is by becoming a cop.
smaller, therefore easier to hide. Not registered with a central authority like, for example, cars.
There is bike registration. https://bikeindex.org
It’s helped track down bike trafficking gangs sending bikes to Mexico. The police just don’t care at all
Love bikeindex, I actually got my stolen bike back thanks to that site. It was literally two years later but still, the police wouldn’t have even made a report probably in the city I was at, with bike theft so ubiquitous.
I’m pretty sure any petty theft is very hard to track down. Not just bikes, if someone broke into your house and stole some minor things it’s almost certainly not gonna get found. Bikes are the same, it’s very easy to resell them and repaint, and nobory registers bikes.
In Poland we have a saying about bike theft, that they won’t even consider looking for it unless you are the commendant’s son.
Because even if they look for it and find it, whoever is riding just says it theirs and there is literally nothing the police can do unless it was caught on video or there is a meaningful identifying feature like a serial number or something else specific and unique.
Seeing a sketchy guy with a black and red bike with the same bike rack you had isn’t enough to prove anything.
If an officer approached me riding my bike around and asked me to prove it’s mine, I couldn’t either despite not being a thief.
Anything that’s not serialized and recorded is basically impossible to find. If you have serial numbers then they can inform local pawn shops, but even then the shops probably aren’t checking serials for anything under $500.
And if the thief just sells it on craigslist then no one is checking serials.
Fun fact. Cops on average have lower IQ and often fail literacy tests. Furthermore it appears that critical thinking is discouraged in the job, with candidates being selected who lack critical thinking abilities over those that have them.
We need to have a chat about your definition of “fun”.
Certain departments specifically have IQ tests, in order to ensure you aren’t smart enough to easily get a better job elsewhere.
I think it’s more nefarious than that. Many departments want a good 'ol boys club where they’re the ultimate authority and they want their officers to fall in line rather than question department actions.
This internet myth has got to die. ONE case in ONE department, a quarter century ago, does not mean it’s a practice.

Can you blame them if they can not find one from after 1999?
Because the 1999 story is the origin of this talk.
Anyone got a non-paywalled link?
It sounds like this could be applied to the military too
The military doesn’t actively exclude smarter people. However they 100% prey on people who are less educated
This argument did not go well
You can’t convince people to do their job with logic when they just don’t want to do their job. After minorities, the thing cops hate most is doing their job.
WRONG! After minorities, it’s poor people. Then doing their job. :P
Come on, don’t disparage our hard-working Boys in blue. Without police who’s going to come to your house to take notes about the crime that you have sufficient evidence to prove, and even have a likely suspect for, and then never follow up?
Nah, they just dont care about some stupid bicycle.
Also - why dont this guy just give them the exact footage? He doesnt want to?
I assume he doesn’t have access to it. He just knows there’s a camera pointing at the place where his bike was stolen, and that the police have access to the footage.
They might not know when in the footage it happened
I thought this had to be hyperbole, so I did the math myself. I’m assuming human history is 200,000 years as google says, and we want to narrow this down to the second the bike disappeared. also that the bike instantly vanished so there’s no partially existing bike.
each operation divides the time left in half, so to get from 200k years (6.311×10^12 seconds) to 1 would take ~42.58 divisions, call it 43. even if we take a minute on average to seek and decide whether the bike is there or not it would still be less than an hour of manual sorting
hell, at 60fps it would only take another 6 divisions to narrow it down to a single frame, still under an hour
I regularly bisect commits in the range of 200k (on the low end) for finding causes of bugs. It takes me minutes. Pretty crazy
Lemmy learns exponential math.
Mostly joking, thanks for doing the math.
History is about 10k years, the 200k years is mostly pre-history. People didn’t write stuff down until they invented agriculture and needed to track trade between owners, workers, etc
True and interesting to note. OOP says ‘dawn of humanity’ though, not recorded history, so taking 200k as ‘human history’ is also valid.
Yeah, I’m used to the narrower meaning of “history”, meaning recorded. I like that definition as it lets you differentiate between it and prehistory.
Definitely a useful distinction.
Just watch at 3X!
Combine AI image/visual-pattern recognition and quantum computing, and this search could be completed before it was even started.
This method will take forever to find the exact moment, said Officer Zeno.
I love you for that joke.
I heard that he wanted to get Officer Thomson and his lamp on the case, but the request form was incomplete.
This post just shows that the police rarely if ever review any video as this method would’ve been learned as a result of repeatedly reviewing video.
I’m a little surprised the police didn’t already know about that method. Seems like they’d encounter enough CCTV footage that’d it’d be standard training.
I once again overestimate the training levels of the police.
For sure they know, it’s just cops are lazy and aren’t paid to solve crimes
I imagine it’s utilized in more “serious” investigations and they just can’t be arsed for theft.
In the US most their training involves how to be more aggressive veiled as training to be assertive.
It’s a somewhat narrow situation. You won’t always have the object of interest in plain view of a camera. What if it’s behind a door? Well now you do have to scrub through all the footage
Part of my job is to review security footage for reported incidents.
If there is a long-lasting visual cue that the event has or has not happened yet (e.g. a window is either broken or not), then a binary search is very useful.
If the event lasts only a moment and leaves no visual cue (e.g. an assault), then binary search is practically useless.
If the event lasts only a moment and leaves no visual cue (e.g. an assault), then binary search is practically useless.
But you will see the event happen though.
It’s a matter of if you can identify who the perpetrator is or not, but at least that due diligence should be done by police, looking at the person doing the crime and see if they can be identified.
But you will see the event happen though.
Not with a binary search.
Edit: just collapse this thread and move on. Cosmic Cleric is an obvious troll.
Well now I HAD to read the thread
What an absolute weirdo.
Edit: just collapse this thread and move on. Cosmic Cleric is an obvious troll.
Screw you, and your gatekeeping censoring.
I replied, saying the comment is not correct, and I gave reasons why, which are valid reasons.
Your reasons for why they were incorrect about a binary search being useless in situations that don’t leave visual cues is that you can simply look for the visual cues lmao, that’s not valid at all
But you will see the event happen though.
Not with a binary search.
Yes you will.
A binary search is just what it says, it’s just for searching only.
When you find that moment in time where the bike was there one moment, and then the next moment the bike’s not there, then you view at regular or even slow-mo at those few seconds of the bike in the middle of disappearing, and see the perpetrator, and hopefully can identify them.
You didn’t get what was talked about here. Re-read the topmost parent comment.
How do you binary search for two people arriving, one punches the other, they both leave?
How do you binary search for two people arriving, one punches the other, they both leave?
In the same way the OP talks about it …
You don’t watch the whole thing, he said. You use a binary search. You fast forward to halfway, see if the bike is there and, if it is, zoom to three quarters of the way through. But if it wasn’t there at the halfway mark, you rewind to a quarter of the way though. Its very quick. In fact, he had pointed out, if the CCTV footage stretched back to the dawn of humanity it would probably have taken an hour to find the moment of theft.
Instead of a bike, you look for the aftereffects of a fight happening (chairs knocked down, tables turned over, etc.). You can even look at how many people congregate around the location of the fight before and after the video as a ‘marker’ to the point of time the fight was happening/just finished.
Edit: One thing we didn’t even mention, AI can also be used these days to notice subtle changes in the video. If a video is a static image of an alley, then two people walk in the alley and fight, even though they leave no traces behind, that moment of the fight is caught on the video with activity/movement. Motion sensor movement, basically.
You are seriously confused. OP specifically said that you’re fucked if there is no visual cue.
You are seriously confused.
And you are seriously trying to kill the messenger.
OP specifically said that you’re fucked if there is no visual cue.
And I’m saying there’s ALWAYS a visual clue/cue, always. Either the bike is there one minute and gone another, or a fight breaks out and trashes the place from the fight. In the vast amount of cases, there’s always a visual difference.
And in this case we’re talking specifically about a bike, going missing.
Your adding things that would allow a binary search work, but the question was in a situation where the only evidence is the conflict itself
2 guys enter one guy punches the other guy they both leave. Nothing is moved no blood was created,
you could not use a binary search effectively to duduce when it occurred.
Your adding things that would allow a binary search work, but the question was in a situation where the only evidence is the conflict itself
I’m describing the vast majority of fights that happen in the public. Also, you’re trying to move the goalposts by focusing on a fight, when the discussion is about the theft of a bike.

What about this hypothetical scenario:
Suppose the objective is to review highway cam footage of the day to verify that a (non-speeding) car with a particular license plate drove past the area / used this route. We know on average cars that drive past this camera only appear for 3 seconds on the footage. How can binary search be used to find the car within 24 hours of footage, if the target car only appears for 3 seconds within the 24 hour video?

I was responding to this …

I disagree with the “leaves no visual cue” part, as I’ve commented on. There’s ALWAYS something caught on the video to help determine things. Maybe not enough, but never nothing.
Maybe I’m not understanding both arguments here but I’d like to understand. I’ve had to review footage of a vending machine being shaken to release drinks.
You have no before or after visual clue as to when the event took place. The only indication is when you physically see it happening. The same could be said for an assault. If nothing is changed in the before or after static still how can you pinpoint the incident?
You either don’t know what binary search is or you completely missed the context of this conversation
You either don’t know what binary search is or you completely missed the context of this conversation
I’m a computer programmer. I know exactly what a binary search is. I’ve written binary searches before.
The search is to get you to the point where you can watch the video to see the crime happening, in hopes of indentifying the perpretrator.
Then you missed the point of this conversation

You’re being intellectually dishonest, in an attempt to kill the message.
This is what was said in the origional OP pic…

Binary search only works on sorted data, i.e. you know which side of the mid point is pointing towards the incident. If the incident leaves no trail, you can’t know whether you can discard the left side or the right side, making it a complicated linear search at that moment.
If the incident leaves no trail, you can’t know whether you can discard the left side or the right side
There’s a moment where the bike is there, then another when its not. The whole video, either way, will either from the beginning up to the point of theft have the bike there, or NOT have the bike there from the point of theft to the end of the video. The marker is the removal of the bike from the video lens.
But the comment you replied to wasn’t talking about bike thefts specifically, it was talking about unspecified situations that don’t leave traces. You responded to someone saying that binary search doesn’t work in situations that don’t leave cues not by arguing against the premise (e.g. “but no such event exists, everything leaves cues”), but by telling them that you simply have to look for the cues from the hypothetical event that didn’t leave any.
but by telling them that you simply have to look for the cues from the hypothetical event that didn’t leave any.
And my point is that the DID leave a clue that a binary search would pick up on, the disappearance of the bike.
That doesn’t apply to the comment you replied to.
Yes, it does…
But you will see the event happen though.
Not with a binary search.
Yes you will.
If the event lasts only a moment and leaves no visual cue (e.g. an assault).
How?
Let’s use the example of a bike theft. We enter into evidence a 4-hour security cam video that shows the thief with the bike.
Scenario A: The camera can directly see the bike rack, and the bike in question is visible at the beginning of the video, and not visible at the end. Somewhere in this 4-hour video, someone walks up to the bike and takes it out of the bike rack. You can use a binary search to find the moment that happens in this video because you can pick a frame and say “Ah, this was before the theft; the bike is still there” or “ah, this was after the theft; the bike is gone.”
Scenario B: The camera can’t directly see the bike rack, but can see the doorway you have to walk through to get to the bike rack. So somewhere in 4 hours of doorway footage, someone walks through the door, then a short time later walks back through the door with the bike. A binary search won’t help here because the door looks the same at the beginning or end of the video. A simple binary search won’t work here because the door looks the same before and after.
This is the explanation that CosmicCleric needs in order to understand binary search.
Because as it is, (s)he’s failing abysmally at demonstrating any understanding whatsoever of that subject.
Nah, they’re just gonna say you can use AI or something, as a retroactive explanation for what they obviously weren’t talking about in their original comment. They’re a troll; they’re not going to budge.
Edit: Case in point. They’re now at the level of mental gymnastics that they’re saying part of their original response implied that they were talking about the capabilities of AI at some point in the future.
That’s how I look for broken mods too. Move half of them into a temp folder, launch the game. If it works, put half of the sorted out ones back. if it doesn’t work, remove another half and try again.
This is all fine and good till it’s a conflict between two specific mods. Damn you FO4 on PS4, why you gotta be like that?
You can put mods on the PS4?
Bethesda made mod workshop worked on the consoles, so you could share the pc made mods.
Small setback that it didn’t support script extender, so it was quite limited. Still better than no modding tho.
To add to your answer, Skyrim also supports mods on PS4/5 and there are even a couple really useful ones. Stuff like the Unofficial Skyrim Special Edition Patch exists, for example.
I have had a much better time w Skyrim mods than FO4 on the PS4 as far as stability goes.
A very limited amount.
Btw, this is why i have given up on Early Access on Steam; can’t disable updates and have to fix your 100 mods then.
I love Steam, but the fact that you cannot permanently disable auto updates for specific titles is definitely infuriating.
When I want to see a broken mod, I just surf over to Reddit.
Yeah, pretty great in my minecraft modding experience
I was looking for this specific comment lmao
Sounds about right. Cops have low iqs
more importantly cops don’t actually give a shit about solving crime.
In England the police primarily exist to keep noise down in middle class areas. I assume it’s even worse in America
That is their primary purpose here too but it just requires more violence and subjection, Americans are extra noisy.
Its likely just a fake story, omitting key details to make the web assembler feel better about his CSS skills.
No, I’ve been in this situation as a victim. My bike was stolen and they said it would take hours to search the CCTV. I told them about binary search, they didn’t understand.
Yeah, seriously. What is even the context of this? We have no idea. The cops might have been like “We need a warrant to look at that footage you idiot.”
Whoever owns the camera presumably has an interest in reducing/solving crime in the area (why else have cameras?), so they would likely be happy to make the footage available to police if asked nicely, with no warrant required.
Yeah, in general, but not necessarily in that circumstance. A lot of time talking to tech people (I’m a softwar engineer) they can can be smug about this while leaving out important context.
Police try to understand anything challenge (100% impossible) (gone sexual) (gone violent)
I once had a friend who was robbed of all kinds of stuff including a PS3, and that the guy was signed into his Netflix changing account profiles the very same day. I told him he can just get a tracking number by calling Playstation and that the active police officer can use it to track them. Thing is, the officer ghosted him for like 8 months despite having everything they needed to immediately find the exact location of the perpetrator actively using the stolen property.
Their method actually does make sense, you just have to remember they aren’t cops to solve (boring) crimes like petty theft. Why get it done as efficiently as possible when you can milk it for hours of overtime? 12 hours of footage means 6+ hours of overtime even watching it at x2 speed, and it’s the kind of thing you can basically have going on in the background. Cops being willfully ignorant for their own benefit makes sense to me
You know what’s even better than milking it for 6hrs of OT? Saying its “to hard” to the victim, going home and then lying about doing 6hrs of OT and getting paid anyway.
Cops lie about OT systemically. Its absolutely rampant. The only consequence they ever get is either a few hrs suspension without pay or fired, and most states are happy to hire them next door immediately so they can do it again.
“Exactly my point. We will not be investing an hour looking at the footage to pinpoint the time of theft, now get out!”
just tell them there is a black man at the moment of theft, they will get on it lickety split!
- Binary search: O(log(n))
- Sequential search: O(n)
- Linear search: O(n)
- Police ethnicity database search: O(0)
No need to search when you already have someone you wanna pin it on.
