Can’t argue with that

Save their dick picks to have a collection at hand so when someone sends you one you can reply with one too.

- Comment on Does being a ‘hero’ mean you are a perfect person? 2 weeks ago:
Doesn’t have to be and in stories its absolutely boring. The wheel of time has a quite great example of a hero that is far from being perfect. The main character has to save the world but due to him being the chosen one he develops quite the superiority complex and becomes arrogant (which is also because kings bow before him) this inner conflict of being absolutely flawed and his duty to save the world largely contributes to the storyline being literally the best book I have ever read. I can only recommend it (but be aware, the whole story is 11.000 pages long)

- Comment on Should Neutron Stars be Added to the Periodic Table? 3 weeks ago:
Here’s what the article says:
Assuming a periodic table in which each element is represented by a 1 cm by 2.5 cm rectangle, 40 rows of 32 elements will take up one meter of space. At this scale, a periodic table incorporating element 10^56^ would need to be 7.82 × 10^52^ meters long. This is problematic, because 7.82 × 10^52^ meters is about 10^37^ lightyears, and the universe is currently estimated span a mere 93 billion lightyears. As such, the new periodic table would be a quadrillion times larger than the observable universe.
The universe is expanding, however, which is good news for chemists and first-home buyers. The rate of this expansion is apparently about 73 km/s for every million parsecs of space, which corresponds to 2 × 106 km/s across the entire universe.8 At that rate, the universe will be able to accommodate the new periodic table in about 10^34^ years.

I just copy pasted it, so thats why its messed up.
- Comment on Should Neutron Stars be Added to the Periodic Table? 3 weeks ago:
IUPAC currently recognises 118 chemical elements. The last twenty have half-lives shorter than Australian prime ministers, and are of equally limited utility to science.
Lmao

Sell me this pen.
Here WE have our latest advancements in manufacturing pens all combined in this new masterpiece. Made from the highest quality materials we could find this pen is made for those who need equipment capable of withstanding all weather conditions. This pen is not for those who worry about getting their hands dirty, its made for the explorers of our world, those who have a desire to advance humanity and are not afraid to go through hell for it and their mission should not fail because of some bad quality products. For just 10.99€ you too can become part of our global movement to advance humanity beyond its limits.
Writing this felt horrible.

- Comment on Exactly Six Months Ago, the CEO of Anthropic Said That in Six Months AI Would Be Writing 90 Percent of Code 5 weeks ago:
As I already stated, AI is my last resort. If something doesn’t work because it has a logical flaw googeling won’t save me. So of course I debug it first, but if I get an Error I have no clue where it comes from no amount of debugging will fix the problem, because probably the Error occurred because I do not know better. I Am not that good of a coder and I Am still learning a lot on a regular basis. And for people like me AI is in fact quite usefull. It has basically become the replacement to pasting your code and Error into stack overflow (which doesn’t even work for since I always get IP banned when trying to sign up)
- Comment on Exactly Six Months Ago, the CEO of Anthropic Said That in Six Months AI Would Be Writing 90 Percent of Code 5 weeks ago:
You can use AI to generate code, but from my experience its quite literally what you said. However, what I have to admit is, that its quite good at finding mistakes in your code. This is especially useful, when you dont have that much experience and are still learning. Copy paste relevant code and ask why its not working and in quite a lot of cases you get an explanation what is not working and why it isn’t working. I usually try to avoid asking an AI and find an answer on google instead, but this does not guarantee an answer.

Please put an NSFW tag on this. I was on the train and when I saw this I had to start furiously masturbating. Everyone else gave me strange looks and were saying things like “what the fuck” and “call the police”. I dropped my phone and everyone around me saw this image. Now there is a whole train of men masturbating together at this one image. This is all your fault, you could have prevented this if you had just tagged this post NSFW.

- Comment on WiFi signals can measure heart rate—no wearables needed 1 month ago:
It may be possible, but I have no clue. It may also be, that the position of the router and the Laptop is important, but that’s probably something you would have to test.
- Comment on WiFi signals can measure heart rate—no wearables needed 1 month ago:
Yeah sadly it is paywalled, but I have been lucky enough to get access to it through my university.
Heres what I found regarding your question in the article:
Fig 1 illustrates Pulse-Fi’s system architecture which consists of three main components: data collection using commodity Wi-Fi devices, a CSI signal processing pipeline, and a custom lightweight Long Short Term Memory neural network for heart rate estimation.
Fig 1:
And this is the Setup they used (left site) and the one that other researchers used (right side):
The parts on how they collected the data:
A. ESP-HR-CSI Dataset
We collected the ESP-HR-CSI dataset from seven participants (5 male, 2 female) in a room of a public indoor library. It was collected using two ESP32 devices, one as the transmitter and the other as the receiver. The sampling rate is 80 Hz, with a 20 MHz bandwidth with 64 subcarriers positioned at different distances. Each participant was measured at distances of 1,2 and 3 m for 5 minutes each. The participants sat in a chair between the devices and wore a pulse oximeter on their finger to collect ground-truth information as seen inB. E-Health Dataset
The E-Health dataset [20] contains CSI collected from 118 participants (88 men, 30 women) in a controlled indoor environment measuring 3 m×4 m (Fig 4). The setup consists of a router set in the 5 GHz band at 80 MHz bandwidth as a transmitter, a laptop as receiver and a single-antenna Raspberry Pi 4B with NEXMON firmware for CSI data collection (234 subcarriers). Participants wore a Samsung Galaxy Watch 4 for the ground truth.Each participant performed 17 standardized positions or activities, with each position held for 60 seconds.
To me it sounds like, that they really just used standard WIFI to collect the data (this is especially true for the E-Health Dataset), since all the processing gets done on the Raspberry Pi.

Health data is extremely valuable. You can use it to serve more personalised ads or even use it to, as example, define prices for health insurance. When you combine it with lots of other data it becomes even more valuable. Also never forget, big corporations track literally everything. Why not add your heart rate.

The Paper: ieeexplore.ieee.org/abstract/document/…/metrics#m…
This is very cool and useful, but at the same time very concerning. While I see a lot of good use cases for this ranging from hospitals to stress recognition in animals I Am also quite scared, that big corporations will use this to spy on us. Luckily currently it is only possible to measure the pulse at about 3m, but it should be possible to increase the range. It may fall short when multiple persons are in detection range, but as far as I have read from the paper they did not test this.

You should use it so that if anyone ever asks you what it means, you can scarce them for life.
