3M executives convinced a scientist forever chemicals in human blood were safe

6 hour(s) ago

ProPublica discovered that 3M Corporation's chemical PFOS was found in the blood of people who had never worked for the company. Despite knowing about the toxicity of the chemical, 3M executives kept it a secret for decades and faced backlash from employees who tried to raise concerns. The article also discusses the widespread contamination and health effects of "forever chemicals" like PFOS, and the lack of accountability for companies like 3M.

### The commenter believes that it is important for companies to prioritize the safety of their employees to freely express their opinions, especially when it may affect the company's revenue or profits. They have personally witnessed situations where speaking up diffused a potentially harmful situation, and they believe that management should not retaliate or silence employees for speaking their minds.

The commenter speculates that Johnson's departure may be related to the PFOS revelation, but the article does not mention if Johnson had shared any additional information with Hansen, such as private discussions, ultimatums, or his own feelings of disillusionment or despair.

### The commenter believes that engineering salaries are often overlooked in cost-saving projects, possibly because engineers are seen as a fixed expense or because their contributions are less tangible. They have observed many projects that claim to save money but do not consider the effort and cost of maintaining and building them. They suspect that some of these projects are created simply to give people something to work on, rather than being a necessary solution.

CVE-2024-4367 – Arbitrary JavaScript execution in PDF.js

5 hour(s) ago

A vulnerability, CVE-2024-4367, has been discovered in PDF.js, a JavaScript-based PDF viewer used by Firefox and other applications. This bug allows for arbitrary code execution when a malicious PDF file is opened, affecting all Firefox users and many web and Electron-based applications. Developers are advised to update to version 4.2.67 or higher and check for vulnerable versions of PDF.js in their applications. A workaround is also suggested, and it is noted that headless use-cases may not be affected.

### The commenter is questioning whether disabling the pdfjs.enableScripting setting in about:config can protect against a potential security issue. They believe that allowing PDFs to run Javascript goes against the Principle of Least Astonishment, which states that things should behave in a way that is expected by the user. They argue that since paper documents cannot run Javascript, PDFs should not be able to either, as they are the digital equivalent of paper documents.

They also point out that PDF.js runs under the origin resource, preventing access to local files but still having some privileges such as being able to invoke a file download.

How a 64k intro is made (2017)

5 hour(s) ago

The article discusses the creation of a 64k intro called Guberniya, released at Revision 2017 by a team of six members. The process involved using various visual designs, a global keyboard hook, Ground Control for animation, and the dear imgui library. Challenges with floating point code and the use of raymarching and rasterization techniques in Unreal Engine 4 were also mentioned, along with the use of post-processing effects and distance fields for modeling objects. The music was created using a VST-instrument plugin and MilkyTracker in XM module format, with the addition of reverb for an atmospheric effect.

Top three comments:

### The commenter has considered writing explanations for their demos but has found it difficult to accurately convey the creative process behind them. They believe that for smaller demos, the size plays a significant role in the creative process and can lead to unexpected discoveries. However, when trying to explain the demo, this aspect is often lost. The commenter struggles with finding a way to convey both the technical explanation and the creative process in their writeups.

### The demoscene has shifted its focus from 64k intros to smaller ones, such as 4k or 1k, and regular demos. This is because creating a high quality 64k intro requires a lot of work and the demoscene is not as big as it used to be. The commenter challenges others to prove them wrong by creating a 64k intro about it.

British engineering giant Arup revealed as $25M deepfake scam victim

8 hour(s) ago

British engineering company Arup was scammed out of $25 million through the use of deepfake technology, where a fake video call with re-created staff convinced an employee in Hong Kong to transfer the money. Despite the incident, the company's operations were not affected, but it serves as a warning for businesses to be vigilant against the increasing sophistication of deepfakes.

Top three comments:

### A worker received a suspicious email from their company's UK office requesting a secret transaction. Despite initial doubts, the worker proceeded after seeing familiar colleagues on a video call. The commenter questions the wisdom of blindly following such instructions, even if they come from a boss, and expresses concern about the potential consequences.

As a result, they are optimistic about the future of travel and in-person meetings, but skeptical about the potential of VR and telecommunications.

The efficacy of duct tape vs. cryotherapy in the treatment of the common wart

This article discusses a study comparing the effectiveness of duct tape and cryotherapy in treating common warts in children. The study found that duct tape was significantly more effective than cryotherapy in resolving warts.

### The commenter shares a childhood experience of having warts and being taken to a dermatologist who suggested a "witch doctor cure" involving stealing a banana, eating it secretly, and burying the peel in the garden. The alternative was cryotherapy, but the commenter tried the "witch doctor cure" and it worked. They express concern about the warts potentially coming back now that they are sharing the story almost 70 years later.

A recent study has revealed that the summer of 2023 was the hottest in the Northern Hemisphere in the past two thousand years, with temperatures almost four degrees warmer than the coldest summer during the same period. This is attributed to global warming, which has been shown to be more severe in recent years.

Eco-brutalism: when angular concrete meets the wonder of nature

Olivia Broome's Instagram page, @brutalistplants, showcases the combination of angular concrete structures and lush greenery in a movement known as eco-brutalism. The images, now compiled in a book, feature buildings from around the world and highlight the balance between harsh architecture and nature. This trend has gained popularity, especially in modern cities, as a way to incorporate plants and nature into smaller spaces.

High performers job hop when they can't find a high performance culture

4 hour(s) ago

High performers often job hop because they are looking for a high performance culture and cannot find it in their current company. This can lead to feelings of isolation, exhaustion, and resentment towards their manager and company. It is important for hiring managers to recognize this and not immediately dismiss candidates with a history of job hopping, as they may be looking for a better work environment.

### The commenter, who is a manager that frequently reviews resumes, does not view "job hopping" negatively as long as the stints were not exclusively short (less than a year). They believe that people put too much emphasis on trying to interpret a candidate's personality from their resume and instead prefer to have a conversation with them to understand their work style, problem-solving approach, and ability to manage constraints.
