My opinion is such that people will not choose to better the environment. People have let the oceans fill with plastic for years. What faith do you have in the the population as a whole to adapt to environmental impacts before they become a massive problem? If people were capable of this, would they not already have adapted? Hell, people have to be forced to wear seatbelts for their own safety.

The article is a little bit confusing on the nature of denaturing.

Alcohol can be denatured by making it literally unsafe to drink (methanol, gasoline, etc), or by making it really unpalatable (denatonium benzoate, vinegar, etc), or both. The list of agents and formulae are here: https://www.law.cornell.edu/cfr/text/27/part-21

True, you can't directly identify the driver, but I would imagine the correlation between number plate and one or a very small number of individuals who have use of the vehicle is strong enough (in most cases) that it could be regarded as personal information.
Geothermal water heating just barely works out in general because efficiency drops with higher temperature differentials. If you would accept you water at noticeably below body temperature it would be great (though I suspect this is ideal for bacteria growth) efficiency. If you want your water as warm as the minimum recommended temperature by efficiency experts you are already in questionable efficiency range. If you go hotter it gets worse.

Real Life Signage Mockups - Boost your workflow, portfolio and presentations.
The article starts with GFW and then goes onto RST packet validation.It's great to see people re-learning the classics. Awesome! Extra points for using "scapy".

The injected RST are often easy to drop once you know what you are looking for. For example Netsweeper RST was easy to spot. In past I caught them with simple tcpdump looking for window size=4096. It worked well "tcp[tcpflags] = (tcp-ack|tcp-push|tcp-fin) and tcp[14:2]=4096"

Anyhow, with L3 RST injection systems it's easy to abuse them. For example - they don't have rate limits usually and they don't verify IP's. By sending a spoofed packet in the direction of such netsweeper / GFW you might be able to trick it to .... generate two packets aginst some host. For example

from scapy.all import *
payload = "GET / HTTP/1.1\r\nHost: censored.com\r\n\r\n"
ip = 'b.b.b.b' # the target IP,
p = (IP(src=ip, dst=ip)/TCP(sport=9999,dport=80,flags="PA")/payload)[IP]
p.show()
send(p, iface="ethx")

If such a packet is directed against an L3 censoring device, it might generate TWO RST packets and send them towards b.b.b.b. The takeaway: L3 packet injecting is hard, and fundamentally flawed. Of course.
Show HN: Make Your Photos Untraceable with Sensor Noise Cancellation
Every camera sensor has a unique fixed pattern noise, called Photo Response Non Uniformity (PRNU). Our new application Photoclean estimates PRNU and removes it from photos. This unique noise not only degrades the photo, but can also be used as a fingerprint to associate a photo with a camera. Once you remove it, you obtain a cleaner photo and eliminate the possibility of camera and photo association. Any feedback will be appreciated.

Some of the depth blur fakery occasionally fails so badly I get dizzy when looking at it because my brain is wired for shooting and editing DSLR images that have been shot in RAW mode. Since I've short DSLRs for almost 20 years now, my workflow is wired to work with the technology and its limitations. And DSLRs have some significant limitations.

Let's forget about the limitations of small sensors and tiny optics for a bit. It's a phone and not a DSLR or a medium format camera with glass that costs more than your car. It can only do so much..

When I shoot I aim for data capture and not how the image looks as shot. How it looks comes later. Which, in overly simplified terms, means: don't blow out the highlights ever and try to keep the noise level in the shadows as low as possible. Or in other words: try to get as much as possible within the dynamic range of the sensor at the lowest possible sensitivity (amplification?) setting of the sensor. (I'm not fond of large grain - artificial or otherwise).

The post processing is essentially about taking more data that your output medium can reasonably render and then offset, squeeze and stretch parts of the dynamic range until you get the tonality you want from the data you have.

Even the iPhone 6 did an amazing job at automating this. But I can't help but feel that with each generation, iPhones get a little bit worse. It tries to do more, which means that when it gets things wrong, the results can get really horrible. And I'm not fond of images that have had heavy alterations of pixels.

Sure, most people aren't going to see this when the image is rendered on a surface that isn't that much bigger than a baseball card. And sure, for most pictures it probably isn't going to be as noticable for the 2 seconds they spend looking at it.

And as someone else pointed out, if you are going to fake focus blur, you're going to have to do a hell of a lot more complex stuff than just smearing pixels with gaussian blur or any other blurring method that doesn't model how lenses actually work.

If you want a really stark example, take a 85mm Petzval lens, or some other "bokeh monster", shoot it wide open with a foreground subject that is 2m away against a background that is 4-5 meters away that contains lots of small highlights. Then repeat the same with various iPhones.

No the iPhone doesn't have a Petzval lens or any other (relatively) large lens. So why try to fake that you do? If you want the visual effects of large glass then shoot with large glass.

As a hobbyist photographer I find it easier when a camera doesn't try to be clever. When it just does what it does. To me a mobile phone camera is more of a "documentation camera" - it should try to capture what you are interested in. It doesn't always have to be pretty. It just needs to be reasonably accurate. Subtly applied HDR tricks are okay since it helps you capture what you are looking at, but when you start to alter pixels, it becomes less useful as a tool.
High schooler here. On-line school is far from perfect. There are two approaches I've seen:

1. The "self-taught" style. This one is being done by my linear algebra class: the prof tells us which chapters to read, sends out notes, and some recommended problems. Periodically, he sends out a take-home test; we work it and send him the answers. This style is helped by the fact that our book is short and concise enough to teach but still be readable. No one wants to read if a chapter takes hours. This approach works great for me, but it requires a more self-directed student to function.

2. The "micro-manager" style. This one is being done by my physics class: the prof uses online, checked homework, multiple zoom calls, requires us to record videos of ourselves solving problems in a "tutorial style", gives on-line quizzes, and attempts to give the same tests on-line as were given in-person. This results in horrible, invasive solutions that give a "proctor" remote access to one's computer, require one to use a webcam to be monitored, and require one to show the space around him using a mirror. This style is awful, wastes colossal amounts of time, but is the option on which teachers fall back when they lack confidence in their students to be self-directed.

Most teachers are going for option 2, which is worse than in-person learning. This may sound cynical, but mot of the tools for "active learning" or "on-line engagement" make students' lives harder, waste their time, and offer no benefit beyond an administrator feeling as though he's "done something".

Edit: can any current student tell me if y'all are getting refunded for room and board, at least partially? Y'all paid for something and are being prohibited from using it, so that seems reasonable.
This is quite different. The ghost flights you describe are empty flights, only flown with a skeleton crew to avoid losing an airport slot.

I'll second that. Growing up, I saw my father drinking lots of coffee every day, and complaining about his "addiction". This simply registered as a bad thing in my mind, so I avoided coffee at all costs until I was about 30. Even now, I still have a "moral" repulsion towards coffee, if you wish. Most non-working days, I don't touch coffee. So, I was able to get through a PhD without caffeine. But, man, how many times was I sleepy. The worse was being sleepy at the wheel. How many times did I not started dozing for a few seconds while driving (never got into an accident though). And no, I was not sleep deprived.

There are people, like me, who are sleepy at times, despite not skimping on their sleep.

I will note though, that for the last 6 weeks I did not drink any coffee, with all the work-from-home thing. I drink only tea nowadays.

Who gets to decide what "harm" is or whether anyone suffered "detrimental effects"? Surveillance is so common and normalized they don't consider the act of collecting so much information itself as a "detrimental harm".

What if that harm only presented itself years down the line? Maybe a creepy stalker who can synthesize mulitple data sets to reconstruct a person's movements or possibly use it against them some way (scammers and fraudsters are increasingly using all these leaked datasets to create a more accurate profile of an individual for more sophisticated attacks/targeting. Your name/address/mobile number must not and can not be considered PII since it's already been leaked probably ten's of times by now).

That's an incredibly shortsighted comment to try and justify developing a system with not even the most basic of security considerations.

I honestly just wish those same people were jailed for 50 years as a result, we'd see a LOT more consideration in the future if they were held personally liable.

Well, to be clear, I was reacting to the specific statement that people only drink three coffees because they have some problem in their life. If you want to cut down on your coffee use, have at it, but do so without casting aspersion onto those who think otherwise.

Otherwise, to me it’s tiresome when any sort of substance is critiqued because it doesn’t fit the standard sober societal narrative, especially because it’s assumed that people are incapable of making decisions for themselves. It is a sort of creeping, subtle Puritanism and is usually totally arbitrary; you’ll see the same people gleefully talk about marijuana yet call tobacco users dumb. These things have costs and benefits and a mature society should be able to rationally discuss them, rather than act like a heavy-handed nanny. As an American living in Europe, this seems to be less of a problem in somewhere like France or Italy that has a tradition of wine cultivation. America seems to always skew to the extremes of over-indulgence or prohibition.

I simply don’t agree with the idea that everything with a supposedly negative health effect is necessarily a bad thing. Intoxication and substance use has played an important role in art and culture for thousands of years. To casually dismiss it just seems really short-sighted.

Perhaps you clone some viral genes into the host genome and remove them from the virus? I don't know what this would do with regards to packing the remanent genome into the capsid.

I was one of two developers on a team of 30 analysts and I would regularly get requests to add employee details (name, manager, director, email) to various spreadsheets. It wasn't difficult but it was a tedious process that took away from far more interesting problems.

Eventually I built a small web app that would allow a user to upload their spreadsheet and have employee details added based on some identifier. It was an enterprise so there was at least three unique ways to match someone. I wrote most of it in one night and spent evenings fixing bugs for a week. While it was very useful, it wasn't "core business" so I didn't get to spend any work time making upgrades.

Eight years later, I still get an occasional email but I no longer have access to the source or server. Definitely a lesson in how long shitty code an live.

I've worked on projects to build skills throughout high school; I'd continue working on those.

JavaEE (now known as JakartaEE) is pretty oldschool and IMHO a dead horse: since Java 9, all the modules have changed package name, breaking massively the old code and those new modules are partly _unnamed ones_, so that means, you cannot use tools such as jlink or jpackage to obtain an optimized JVM image.

JavaFX is far better than Swing for Desktop applications, but if you really want to develop a Desktop application, consider C++ and Qt Framework, especially for performance. Also in this case, now JavaFX is called OpenJFX and comes as modular approach.
