In fact, there was a famous de-censoring that happened because the censoring which happened was a simple "whirlpool" algorithm that was very easy to unwind.
If media companies want to actually censor something, nothing does better than a simple black box.
You still need to be aware of the context that you're censoring in. Just adding black boxes over text in a PDF will hide the text on the screen, but might still allow the text to be extracted from the file.
Indeed. And famously, using black boxes as a background on individual words in a non-monospaced font is also susceptible to a dictionary attack on an image of the widths of the black boxes.
And even taking sharpie and drawing a black box doesn't mean the words can be seen at a certain angle or by removing the sharpie ink but not the printed ink.
Really, if you need to censor something create a duplicate without the originals. Preferably literally without the originals as the size of the black box is also an information leak.
Curious anyone know if the specific censoring tool in the MacOS viewer has this problem? I had assumed not because they warn you when using the draw shapes tool that text below it can be recovered later and they don't warn you about that when using the censoring tool.
This was pretty different though. The decensoring algorithm I'm describing is just a linear search. But pixelation is not an invertible transformation.
Mr. Swirl Face just applied a swirl to his face, which is invertible (-ish, with some data lost), and could naively be reversed. (I am pretty sure someone on 4chan did it before the authorities did, but this might just be an Internet Legend).
A long while ago, taking an image (typically porn), scrambling a portion of it, and having others try to figure out how to undo the scrambling was a game played on various chans.
Yeah but if you read about him it serves as a rallying cry for right wing types since he's an example of the candaian legal systems extreme leniency. This guy should be in prison forever and he's been free since 2017. Look at his record of sentencing. I love being a bleeding heart liberal/progressive and all, but this is too far.
Furthermore, don't look too hard at Isreal and it's policy of being very, very open to pedophiles and similar types.
A completely opaque shape or emoji does it. A simple black box overlay is not recommended unless you that’s the look you’re going for. Also very slightly transparent overlays come in all shapes and colors and are hard to recognize whether it’s a black box or another shape, so either way you need to be careful it’s 100% opaque.
The only sane way to bring back manufacturing is investments like the chips act.
Think about it this way, you are a widget manufacturer trying to place a new factory. You could put it in say Canada and enjoy cheap imports and exports of your product globally. It's cheap to produce and easy to sell.
Or you could place it in the US, but now you are looking at a minimum 10% tax on importing the resources you need. On top of that, a significant portion of the world (especially the richest nations) are tacking on an addition 10% or more tax on your product because it came from the US.
Would you build a factory in the US? Maybe if you can source everything in the US and you are fine with your primary market being only the US. Otherwise, it's a bad business move.
When talking about something like semiconductors, global access is really important to be profitable. Low or no tariffs and the proximity to China and other raw resources powerhouses is a major reason why so much of the semiconductor industry is in Asia.
Neonazis tend to like the idea of Israel while hating the occupants. They hate sending aide there but love it if Jews move there.
The notion of a Jewish state was an OG Nazi idea (see Madagascar plan). They wanted a place to send their unwanted citizens.
On top of that, core to most fundamentalist Christian belief is that utopia will happen after a strong Israel gets involved in massive wars. That value is why you may see neonazis cheering on Israel as an aggressor because they believe it'll lead to utopia.
This is why mixing support for Israel with whether or not someone is antisemitic is silly. Israel isn't the Jews and Jews aren't Israel.
Ironically, the anti-medical viewpoint is FILLED with naked capitalism. The people most distrustful in the motivations of modern medicine seem highly inclined to buy supplements their favorite anti-medical media is almost certainly hawking.
This isn't to say medicine is perfect, but you really should be questioning the motives of those calling it all a sham. Due to regulation, medicine is generally pretty well backed up.
It'll depend on the allocator. Generally speaking, the better an allocator is at minimizing fragmentation, the slower it's going to be with new allocations.
That's why bump allocators are wicked fast, but make the trade-off the article mentions.
Interesting. Looks like it the line isn't able to take the energy (I'm guessing voltage is already too high) they dump the energy into a resistive heater.
Makes sense, it's just going to be heat anyways. I wonder how often that happens vs the energy getting dumped into the line.
Sure. Because windmills and photovoltaics grow naturally from seeds. You need quite a bit of an equipment to put up one windmill. They are usually built in some distance from an existing road. So you need special service roads. Those need to be wide and take heavy load because the equipment like cranes need space and are themselves heavy. Then you need special transport because main components like propellers are oversize load. Then you need to transport them hundreds for kilometres…, and then you need the rest of the infrastructure to distribute generated electricity. Yes, let’s compare apples to apples.
Yes and what's the service life for that windmill or solar panel? What's the service life of the distribution system?
And what was the cost to build out and constantly repair the refinery?
The problem you have with your talking points is that solar and wind both have decades of service in them whereas fossil fuels are single use product. Further, once the infrastructure is created large portions of it can be reused when solar and wind hit their end of life. You only need new lines and roads for new installations.
All energy collection will have some environmental impact. It just so happens that fossil fuels have an outsized impact for the energy they create.
I'm not an absolutist about crude oil. It'll likely have a place in society for a long time.
With that said, it's a matter of degree and where it should be deployed.
If, for example, burning 1 gallon of gas sets up a power generation which produces the equivalent of 20 gallons of gas without emissions, that's a worthy trade off.
As it turns out, that's roughly the energy trade-off for new solar/wind installations assuming a pure fossil fuel grid.
What you are saying isn't a gotcha. The entire cycle of CO2 released for fossil fuel use is not comparable to the CO2 released installing renewables. That some is released is meaningless.
Asbestos is chemically inert. Yet it causes lung cancer. Why?
The answer is simply that it continually damages the cells in the lung due to it's needle like structure.
I assume (but critically don't have proof) that if we find a cancer link to plastics it will be due to a similar sort of structural interaction. I don't think the specific type of plastic matters, though I'm sure some will be worse than others.
In this specific case, very unlikely that plastics as a whole cause cancer due to some structural form issue. Saying ‘microplastics’, to compare to asbestos, is similar to saying ‘silicon’. Asbestos is a particular form of crystalline tube shaped silica (aka silicon dioxide).
Many other forms of silicon are both cancer causing, and completely inert.
I suspect plastics will similarly have only small portions that are really nasty. We’re making a huge variety of novel types though every day. Which is part of the concern.
what we call ‘plastic’ has such a huge variety of molecular weights and compositions it’s like trying to find common ground between say nickel, stainless steel, and uranium.
We already know some plastics cause cancer, and some precursors to the same plastics cause cancer.
And a bigger issue IMO is plasticizers which modify the plastics structure to make them more malleable and less brittle.
Even asbestos divides into several families with very different levels of carcinogenicity. Crocidolite "blue asbestos" was first banned long ago due to its severe effects, but chrysotile (white asbestos) is far less dangerous.
There is this interesting study from last year that looks at the health effects of chrysotile, in a population exposed to far more of it than possibly anywhere else on earth: https://pubmed.ncbi.nlm.nih.gov/38247448/
Interesting but also seems like something that'll be a bit problematic to work with when vandalism happens.
The sensor is right outside the box, it'd be better if that was recessed and harder to see/access (I can see these little black dots getting little dabs of paint).
But, tbh, I don't really see the utility of this over equipping the postman with a scanning gun (or even phone) that does the same thing. You might still want 4g and solar panel, but I'd use those for a "there's something at this box" and not "let's scan it to let people know it's on the way".
Postmen already have them if you've paid for postage online and requested collection.
Post boxes in the UK are not like US mailboxes, these are communal and for outgoing mail only. Postmen (typically, exception per first paragraph) only being your incoming mail, and it goes in a letterbox in or near your door, almost always depositing the mail inside your house; there's no way for them to reach outgoing mail you've left there.
If media companies want to actually censor something, nothing does better than a simple black box.
