Really weird that nobody in the thread is pointing out that this is basically a website that says "give me your photos, specifically from protests, which have details that you want to keep private". It doesn't matter that it theoretically all happen in the browser. You can serve different versions to different IPs etc. Every heuristic in me would be screaming don't use that if I would have a need for such tool.

It's a static site running on GitHub pages, over HTTPS, directly out of a linked repo so you can examine the source code. I literally could not imagine a more transparent way to serve this application. The only way an attack vector is possible here is if you think GitHub themselves would maliciously inject an altered version of the code in the repo, and even then you'd be able to see the code and network requests in…

That's assuming the author can be trusted. The link is not pinned to a specific commit so their is no way to know if the code is updated later without auditing it every time the tool is used.

I am not aware of facts supporting the claim that african americans live under an authoritarian regime. I am aware that a number of african americans have been unjustly killed by police. That is a different claim than african americans are systematically oppressed by the US government. For instance, compare what is happening in the US to a real authoritarian regime such as the USSR. The government made millions of in…

Why do you believe what you're told about a faraway land, but disbelieve what you can see for yourself in your own community?

why are you asking loaded questions?

The protests were sparked by the lack of accountability of the police resulting in police brutality. The violent people among the protesters are subject to the same incentives. The more they expect to be held accountable, the more likely they will refrain from violence. Anonymizing photos of the violent ones is therefore likely to support their actions by making accountability less likely. To scrub ethically, limit i…

When the US inevitably does turn into an authoritarian dictatorship, I think people would be happy if there wasn't copious amounts of proof they were on the streets protesting.

I should add: In all of the streams and pictures I've seen, all (most?) the looters or violent people were wearing masks, ensuring their anonymity. If anybody's being protected by measures like this, it's your average peaceful protestor.

haveibeenpwned is explicit about not entering passwords you use . If you want to check a password that you intend to use then download the database and check for yourself.

I don't get it. If I check for a password I used before, presumably I want to keep using it if it's safe. Otherwise what's the point?

On haveIbeenpwned (at least last time I used it), you can either check the hash of your password, or the first N characters and it will return a list of leaked passwords that match

i would ask you the same thing

you have never met me, but seem to know a whole lot about what i do and do not know

how did you get this information about me, and how do you know it is true? or are you just making a bunch of baseless assumptions?

Everyone in this thread knows you live closer to Minneapolis than to Ürümqi. You started the thread by discounting the difficulties of black people in USA. You wanted someone to give you some "facts" to "support" the claim that racism is a problem. All of us made the same assumption based on that evidence. We don't need to imagine anything else.

>Have you got an actual example? Of a cop murdering a black man in broad daylight and not getting charged for it? Hell, here's an example I just pulled up for someone else of a 12 year old black kid being murdered while he played airsoft in the park[0], the cop faced no charges and was subsequently hired by another police department in the same state. It's like paedophile priests getting shuffled around by the Cathol…

You can't even defend it with the infamously flexible ethics of utilitarianism, because the strategy has been employed numerous times - and it always results in the utter ruination of those that pursued it.

I had named an example, the one which just happened. Reading that question sandwiched between my last sentence and your next one I was legitimately unsure what you were asking. Therefore I made it clear which question I erred on the side of you asking, and proceeded to answer. Please consider considering your own lack of clarity in communication before insulting others in the future.

You want another example of riots leading to change? The Civil Rights Act of 1968 was signed into law during a storm of riots that had broken out following the assassination of MLK.

Easier to select an area and delete it from the layer entirely so that a transparent hole is left. Then make sure you cleanup EXIF and other metadata or you may have the original image still in a thumbnail field at reduced fidelity. Free online metadata viewer http://exif.regex.info Powered by FOSS (Perl-based) https://exiftool.org

Do not keep it transparent! The Gimp for example keeps the underlying colour data, and just sets the opacity to 0. this bug (closed as Expected Behavior) has a demonstration: https://gitlab.gnome.org/GNOME/gimp/-/issues/4487

I didn’t specify a program to use, but I did not know this. A step in my personal workflow I neglected to state is to flatten all layers but I’m not sure what the best way is, so I’ll just say I am open to ideas for better ways.

There should be a test suite for image editing applications which will validate the different ways of editing a file to see which ones work as expected and which do not. I’m thinking something similar to web standards test for browsers. Does something like this already exist?

>Yes, deliberately preventing anyone from providing care or defense for a person who's being murdered makes you an accomplice to the murder. Are we in agreement that this was documented as happening, and the other cops present were accomplices in the murder of George Floyd? If so, why do you think they aren't being charged? >Who should the city of Cleveland have charged justly to prevent this? I assumed GP meant Minn…

Semantics... We likely agree on the other officers' responsibility/duty both to police the unlawful/unjustified actions of their colleagues and to protect the life and liberty of Mr. Floyd in this situation. I think murder requires some threshold of intent deliberation and I'm not very familiar with the details in this incident just yet... but on it's face it's doubtful the officer intended to kill George Floyd and c…

I would recommend watching the George Floyd murder video, and not for morbid reasons. I think it helps to understand how calmly, with his hands in his pockets, this cop sat on Floyd's neck for 8 minutes (the last 3 of which Floyd was unresponsive for) while an EMT asked for a pulse to be checked. This was not an accidental death.

I don't think the man who killed Tamir Rice understood that he was shooting somebody holding an airsoft gun, but if the killer wasn't a cop then I seriously doubt that they would have decided his actions in that situation were reasonable as self defence -- they probably wouldn't clear me of all wrongdoing if I claimed that a 12 year old kid pointed an airsoft gun at me before I killed him. There's a double standard. Despite the victim being a 12 year old, I can see how this is less egregious than what I consider to be the clearly intentional killing of a known-to-be-helpless George Floyd -- I brought it up as an incident in your specific community where this pattern of violence bubbled up so dramatically that it received nation wide news coverage. I think you misunderstood some facts around the hiring and firing of the cop. He lied on paperwork at the original (Cleveland) police department, which is the technical reason he was fired -- it came up during a review of him following the shooting. The other (Bellaire) police department knew what they were buying. A quote from the link in my last reply:

>“He was cleared of any and all wrongdoing,” the Bellaire police chief, Richard Flanagan, told The Times Leader of Martins Ferry, Ohio, adding that it was unfair to “crucify” the officer. “It’s over and done with.”

I could see there being a causal link between how your city handled this incident (as well as others like it) and how much violence you're seeing now, a few years later, when everybody is focused on this other prominent example of the pattern.
