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 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’s plenty of cases where they don’t look for cars either.
Or the cops themselves just straight up steal the car themselves.
My wife’s car was ordered to be towed by, according to the impound lot, the police.
Neat thing was that there was no ticket with the car, no police station within 3 miles had a record of a ticket for her or the car, and the area she had parked had no signs that suggested it was illegal to park where she did, nor does the city have any ordinance about overnight parking.
Best we can figure, is a cop or the tow company that works with the city, just decided to tow a car for funsies and the 500 bucks it took to get it out of impound.
The police and every organization associated with them are corrupt to the core.
Reading that I almost had a thought like it must have been a mix-up or something, but no, US police will murder people with less thought, so that type of fuckery is completely expected.
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.
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.
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!
It probably depends a lot on where you live. My wife’s bike got stolen and she was woken up by police coming to check on it (one of the maintenance guys at our apartment noticed a man at 7-Eleven riding it and recognized it; came back running to check if it’s indeed missing and called the police). We fully expected the police would do nothing about it (it was the cheapest Walmart bike), but an hour later they called that they found the bike and have the culprit in custody. It did help that the bike was a girly mint green with a wicker basket, so they instantly recognized it when they saw it.
Then again, in San Francisco, when my wife got her car window smashed and wallet stolen (she was late for class and dropped her wallet under the car seat, didn’t stop to take it; but it wasn’t the wallet that caught the thieves’ attention, it was the breast pump bag that looked like a laptop bag; they threw it on the floor when they saw what it was), we never heard anything back from the police.
And they absolutely hate ever doing anything
about bicycle theft in particular.FTFY
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.

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?
Removed by mod
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
when they just don’t want to do their job.
It might also be a matter of getting a directive from their management not the care, because there’s not enough cops to go around for the ‘important’ stuff.
They don’t want to waste their limited time for simple property theft, which is ironic considering that’s what police are supposed to be doing (stopping theft).
The answer would be then to hire more police, but unfortunately that would mean higher taxes for the citizenry, and that seems to be a hard glass ceiling.
Wrong
The police exists to protect the status quo. Try overthrowing any immoral law or legally but immoral behavior and you’ll see how efficiently they move about.
Before handing out life advice maybe try it IRL and see how it goes. It’s kinda fun.
I tried being born rich but it didn’t work this time around. Maybe next re incarnation?
No, the police just don’t want to do any work. In my hometown you can’t get the police to do shit unless you are a black man who “fits the description” or “smells like weee” then they will gladly try to make your death look as much your fault as possible.
More police wouldn’t cost more money if they stopped buying tanks.
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
edit: to use the entire hour we’d need a couple more universes worth of video time to sort through, 36.5 billion years worth to be exact. or a measly 609 million years if we need to find that single frame at 60fps
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.
Well, in this case it must have been recorded on video, so could as well start recording before inventing the writing
Just watch at 3X!
Combine AI image/visual-pattern recognition and quantum computing, and this search could be completed before it was even started.
We can go deeper!
A minute to decide if there is a bike in the picture really ?
As a robot, finding bikes in pictures is really hard, okay
Takes time to precisely seek to each timestamp, but really I just meant that an hour was reasonable even with a lazy cop doing the search
They must be really bad at solving CAPTCHA
Ever heard of a logarithm? If you haven’t, you just reinvented it.
Also, your math is wrong: log base 2 of 200,000 is ~18
You did 200k years. You need to do 200k years as seconds (the 6.311e12 they mentioned). Their math is right.
Not sure why you’re acting like they claimed to invent the logarithm, either…
This didn’t go down well.
IT consulting pro-tip: Customers would rather pay for your time and expertise, than be made to feel stupid that they didn’t think of something so simple themselves.
After working in desktop support for a year after college, I realized that people just wanted their problem solved and to not feel frustrated. That realization made my job immensely easier because I pivoted from copying a file in 30 seconds and walking away to talking to them a little bit and letting them feel good after we were done. My ticket closing speed slowed down a little but people felt better and I consistently got positive feedback.
Dude same here. I usually say stuff along the lines of ‘yea it took me forever the first time to figure it out’ or ‘it’s a common issue that a lot of people have, I’ll get it sorted in a sec for you no problem’. Make it seem like they’re not stupid, regardless of the truth and then fix it, keeps em happy and more willing to cooperate with you as well.
I also talk through what I’m doing and if they show interest I’ll teach them so they can fix it in the future, ‘ah I’ve seen this before, took me like a hour to figure it out on my computer, for me it was a chrome update that broke how downloaded files open. Here let me right click the file, and go to open with, we hit Adobe pdf and check the always open with this program button, that should do it let’s test it out. OK seems like its good to go. Let me know if you have any more issues’. If they don’t show interest then it’s no problem.
Are you my kindred spirit!? :P Thats almost exactly what I do too!
My favourite is when someone apologies for not knowing something or having dumb questions. Apart from “there is never a dumb question” because there usually isn’t, I typically respond with “if everyone already knew how to do everything, I’d be out of a job” which always seems to go down well.
Some of my favorite help desk moments are those times you get to a be teacher for someone that’s genuinely listening and happy to learn.
My go to is usually ‘everything is easy if you know how to do it’
When I started in support 15 years ago my boss said: “First you solve the person, then you solve the problem”.
He was a good dude.
What would you recommend for solving people? Does a household base like NaOH suffice?
Solving, not dissolving.
Customers typically stop complaining once in aqueous form.
What about in soap form?
Same story here, actually. I cut my teeth on internet telephony (modems) support for an ISP. People would call up furious about not being able to connect. I learned that chatting people up during a long Windows reboot did a lot to humanize their struggle and get them to calm down and loosen up. First few times were organic, then I started looking for pretenses to do this, just to bring the temperature down for the rest of the call.
Call centers tell you to empathize but that’s not something you can teach. You can either do it or you can’t. So they give those terrible scripts, and then some of them require you to speak the scripted lines, even when you know all it does is piss the caller off.
No hears that scripted pablum at the start of call and thinks it’s genuine. No one. “I’m sorry to hear your having issues sir, but I’ll be happy to assist you.” genuinely comes off condescending at this point. They know you know it’s scripted, they know you know the representative has to say it, but they make them do it anyway.
Here’s what I found doing ISP call center work, and it worked virtually every single time: imply through tone and pointed comments you’re as frustrated as the called with how shitty the service and the hardware is. They’re never prepared for it, it always catches their anger off guard.
Don’t outright say “Yeah, Cox is absolute dog shit, and that POS gateway we make you pay for isn’t worth the cost of the the technician we’re sending out to ‘fix’ it.” You’ll get in trouble for that.
But if you’re careful and creative, you can make them appreciate you think that
Just yesterday, I was helping this manager set up a new system of ticket line (the kind where you get a ticket number and wait for it to be called in a panel). He complained that they didn’t have a proper printer just for these tickets, so he made the tickets in excel and printed them. To the right of the number, someone would mark the service, from a list of 6.
“Why not use a single letter prefix and print different piles of passwords? (A01, A02, A03; B01, B02, etc)”
That’ll use too much paper. We’ll also need more tickets than before
“That will use less paper, you can print 2 tickets using the same space. Also, the amount of tickets always depends on the number of people that show up, but you’ll have a better idea of which service is being needed each day”
Mr manager didn’t like the idea and moved on to another problem.
Eh, it’s less intuitive than you might think, as someone who already knows how to do it.
I once had to explain this process to a software engineer who was quite senior to me. The guy wasn’t any idiot, he was a pretty competent engineer, he just didn’t know this trick.
The cops might even already know how to do it, they just don’t want to, because they’re cops.
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.
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.
They probably do know. They just aren’t meant for protecting your personal property
Right.
What they really want to say is “We aren’t interested in investigating your personal theft. Things get stolen all the time and we really can’t be bothered. You are not important to us.”
But they can’t say that, so they instead throw out some excuse that puts the onus back on the other person.
You dont quite understand.
They aren’t here to protect your property.
Or you, really.
Not unless you have a couple million in assets, then all of a sudden it’s all hands on deck, let’s get this bicycle back.

They can, and do, say that.
Edit: just without the you’re not important to us part.
I dunno. “Don’t attribute to malice that which can be sufficiently explained by stupidity.” I can totally believe that the average police officer has not thought this through. “5 hours of footage! We don’t have 5 hours to look for one bike.”
“Don’t attribute to malice that which can be sufficiently explained by stupidity.”
And Detective Conan Doyle O’Brien really did just let his bro fuck around and watch porn and even bring a stripper into the station during footage reviewing hours. Of course, Stuart was quite shocked to hear he was not invited to the stag do later that weekend
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
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.
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.

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.

I never said they work 100% of the time. I said they work most of the time, which is a true statement.
An event happens in time, that event has a duration, if you can detect that duration then a binary search works perfectly fine.
And even after the duration most times events change the environment around them, which stay statically changed, and are detectable.
So much work to try to Kill the Messenger. Maybe organizations don’t want people to think they work so people won’t demand that they be used, causing more work for them.
I never said they work 100% of the time. I said they work most of the time, which is a true statement.
That’s also what the comment you claim to disagree with said, so why are you even arguing?

Right. And when that happens, it’s covered by the second paragraph of the parent comment:
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.
Situations where binary searches aren’t useful are covered in the third paragraph of the comment:
If the event lasts only a moment and leaves no visual cue (e.g. an assault), then binary search is practically useless.
You’ve claimed that you disagree with this, but have yet to explain why you disagree beyond saying that there would be visual cues. Except that they’ve already said that binary searches work in situations that leave visual cues. You haven’t explained how a binary search can work in situations that leave no visual cues except by claiming they they would, except if they do, then the person you claim to disagree with has already said that binary searches are useful.
You’ve claimed that you disagree with this, but have yet to explain why you disagree beyond saying that there would be visual cues.
I have explained it, multiple times. I disagree that there would not be visual clues most of the time. I can’t prove a negative I don’t belleve in, to me its a false scenario that doesn’t (mostly) happen. In fact, the whole point of my very first comment was to rebut implicitly the ‘no visual clues’ clause.
Each comment is not atomic, on its own, its part of an overall conversation being had. To try and do so otherwise is just to play “gotcha” and is intellectually dishonest.
But you will see the event happen though.

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.

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. The route is used 24/7 by many identical cars throughout the day and night, and that our target car is one such identical car, with the only difference being the license plate. 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?
You didn’t get what was talked about here. Re-read the topmost parent comment.
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 have no before or after visual clue as to when the event took place.
That wouldn’t necessarily be true. If you shook it hard enough to move the contents inside the vending machine and the vending machine had a glass front then you would have a static change that would last from the time the event happened until a human being came to work on the machine. That change would be detectable.
Or from the shaking the vending machine is moved an inch forward and an inch to the left. That change would be detectable.
Everyone arguing against me is trying to focus the point that the event is such a short duration that it’s not detectable afterwards, and what I’ve been arguing the whole time and that people keep ignoring is that most of the time after an event happens that the environment around the event changes, and it’s detectable afterwards.
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

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?
Yes.
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.
I’m not trolling, and I stand by what I said.
And to recap, what you said is:
If an event lasts only a moment and leaves no visual cue, you will see that event happen using a binary search.
Which is, of course, false.
And to recap, what you said is:

It’s not false if the event changes the environment around it, which was my point.
You incorrectly assuming a completely clean and static event that does not affect anything around it afterwards, and in the real world that’s just not usually the case.
And for the record, I never said it works 100% of the time.
I’ve written binary searches before.
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
I never said it works 100% of the time. This that it would work most of the time. And I make that statement based on the fact that usually the environment changes around the event, or the event happens long enough to be detectable, if not by humans, then by AI.
In all of my comments I’m assuming that that focal point of the crime is visible.
But even if it wasn’t, if the person stealing the bike knocks over a trash can while doing it and that’s in the camera view it would still be useable. Or if a crowd congregates around the focus point and looks around for the bike, that would also make a binary search feasible.
That’s always just been my point, that a binary surgery more often than not works because most times the environment around the event changes in some way, from subtle to extreme.
You would have to be confident that said change in environment was done by the bike thief. What if that knocked over trash can was done by some unrelated bored teenager twenty minutes after the bike was stolen?
It might be better to use some software to remove any frame of video that is identical to the one before it, no motion is taking place, etc. then manually watch the much shorter video of “only when stuff happens.”

Well, the change would happen, the human will be noticed, and then they can watch that moment in time on the tape to see who did it. The binary search would be about shortening what portions of the video tape a human/AI would have to review manually.

So, I hope you’re not under the impression that I’m advocating binary search as the ONLY way of doing a search. I’m just staying within the confines of the subject as brought up by the OP, which was about binary searches.
At the end of the day its about detecting the change/aftereffect, and not the search inandof itself. A binary search just helps you narrow down the video you have to watch manually, especially when there’s allot of it to review.
I’m just a random guy stumbling across this thread hours after the fact. I want to say that after reading many of these comments. I feel like I’m starting to get a handle on what your position is. You aren’t wrong, but you are communicating your idea horribly.
Your position seems to be “Thankfully, many crimes do leave behind lasting visual cues, so you can still do a binary search for those situations if you are clever about what to look for.”
What you’ve actually been communicating is that “If there really was no lasting visual cue, then just find a lasting visual cue anyway, then do a binary search on that and it’ll work!” - It’s all about how you choose to present, order, and emphasize your comments. Your message is more than just the words you type. I hope this message helps clarify the debate and confusion for you and anyone else who stumbles upon this long chain.I appreciate you responding kindly, and your thoughts, thank you.
What you’ve actually been communicating is that “If there really was no lasting visual cue, then just find a lasting visual cue anyway, then do a binary search on that and it’ll work!
What I’ve been attempting to communicate, and I think have been expressing that, is that “no lasting visual cue” is not right (most of the time), its incorrect, and that there’s (almost) always a visual cue, and that you can do the binary search because there is. Not maybe, but there is, lasting visual cues (most of the time).
I disagreed with the point being asserted by the comment I initially replied to. I think people are getting hung up on my very initial comment, where I implied instead of being explicive, thinking my assumption was a well known one, just based on how I see the world operate (humans are messy). But how those replied to me seem that its not well known (or just not realized).
In hindsight, I should be more explicive, but that’s a horrible way to have to communicate, like if I have to pass every comment through a lawyer before posting it. You’d think people instead of instantly attacking would just have a conversation about try to understand my assumption. That didn’t come up until WAY later in the conversation tree, and only by a single person. There was way too many comments just attacking me with every hypothetical possiblity just to try and prove me wrong, and that, was wrong of them to do. Its not conversational, its bad group think.
Your message is more than just the words you type.
I was just telling my wife that the other day, its how you say that matters as much as what you say. I’m actually a well spoken person (on a good day at least). I’m honestly going to blame some of the confusion not on me, but on others with their hypotheticals, and confluencing how you scan a video, with how you search for sections of a video to scan, as adding to the confusion.
I hope this message helps clarify the debate and confusion for you and anyone else who stumbles upon this long chain.
Well, I think (saying this in 3rd person) what null was trying to do (gatekeeping censorship by telling others to not read my comments and calling me a troll) is really, really wrong. and bad for Lemmy, and I would have liked to have seen more people call him out on it, but instead he was rewarded with up votes. I truly don’t believe I deserved that, or that ANYBODY deserves that, and that his comment should be moderated.
And only because you mentioned it, I don’t feel confused, I feel anger. Anger over how I’ve been treated. It was just supposed to be a friendly conversation, expressing a counterpoint, and people responded by doing things they would not do in public to another’s face.
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.
We just give all the tools to solve crimes to people who have no idea how to use them, no biggie.
*have a perverse incentive to not know how to use them or to know things about their job generally.
Sat on jury duty. We literally said not guilty because the officer was supposed to follow a process for line ups and they didn’t even do the bare minimum. They were like we got out guy
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 would still at least figure out one of the conflicting mods and could look for updates / further information about conflicts.
Edit: On PC that is.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.
Just enough so that you could get a conflict between two of them.
I only have it on PS4, and yes there are lots of mods in the workshop. There are obviously limitations.
Every few months I try installing various mods to make what I want out of it, darker nights, flashlight mod, weapon and armour changes for a more hard core experience, etc, and end up with 15 or so mods installed.
Start a new hardcore mode, get just about past diamond city, and the game invariably starts crashing.
No idea which one or ones are causing the issue, and in the end I get annoyed and go play something else.
Then it’s even easier, just remove one of them
When I want to see a broken mod, I just surf over to Reddit.
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.
Yeah, pretty great in my minecraft modding experience
I was looking for this specific comment lmao
“Exactly my point. We will not be investing an hour looking at the footage to pinpoint the time of theft, now get out!”
Show up with a box of donuts.
“Hey, look what I got for us to eat while looking at that tape!”
“Oh, I don’t think those donuts will last more than ten minutes here!”
“No problem, I know a way that won’t take that long…”
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.
Sad meme very relevant
I’m sure it didn’t go well. If it was somehow framed in a sycophantic way where the police were led to believe it was their idea, I’m sure it would have gone better. Wait that might not be too difficult to do.
You just have to say there was a weird technique the Nazi’s liked to use.
They probably already know all Nazi techniques.
Na. If it’s British police it’s just an excuse. All they’re there for after all these years of Tory cuts is to give you a reference number so you can make an insurance claim.
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.

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.
It would have taken 5 minutes at most
