4.How to Harden GitHub Actions: The Unofficial Guide(How to Harden GitHub Actions: The Unofficial Guide)
Over the last three years, researchers have raised concerns about the security risks of GitHub Actions, highlighted by two recent incidents involving supply chain attacks. In December, attackers used a vulnerable GitHub Actions workflow to inject a cryptominer into the Ultralytics Python package. In March, another attack exploited common vulnerabilities in GitHub Actions, compromising a contributor's access token and allowing unauthorized changes to several repositories.
To enhance security, organizations are encouraged to review and strengthen their GitHub Actions configurations. Key recommendations include:
- Set Workflow Permissions to Read-Only: Change default permissions to read-only to prevent unauthorized modifications.
- Limit Use of Actions: Only allow verified or trusted Actions to run in workflows.
- Govern Workflow Adoption: Control which repositories can use certain workflows and restrict self-hosted runners to specific repositories.
- Disable Automatic Pull Request Actions: Avoid enabling settings that allow workflows to create or approve pull requests automatically.
Additionally, it is crucial to implement branch protection rules to safeguard against malicious code being merged. Secrets management is also vital, as improper handling can lead to security breaches. Organizations should use repository, organization, or environment-level secrets while ensuring they are only accessible when necessary.
When constructing workflows, manage permissions carefully, avoid using third-party Actions without restrictions, and mitigate risks associated with high-privilege triggers. Organizations should also be cautious with self-hosted runners, ensuring they are isolated from public repositories and monitored for unusual activity.
In summary, organizations should focus on minimizing third-party risks, managing permissions and secrets wisely, and employing security best practices to protect their GitHub Actions workflows. Tools are available to assist in identifying and addressing vulnerabilities in GitHub Actions configurations.

7.Yes, the Apple II MouseCard IRQ Is Synced to the VBL(Yes, the Apple II MouseCard IRQ Is Synced to the VBL)
The text explains that the Apple II MouseCard's interrupt (IRQ) is synchronized with the vertical blanking (VBL) signal, which is crucial for graphics rendering on the Apple II. The author faced issues with flickering in a game when emulated but found that it rendered correctly on real hardware.
To determine the synchronization, the author engaged the Apple II development community and investigated the MouseCard's operation. It was confirmed that the MouseCard IRQ is indeed timed to coincide with the VBL.
When the MouseCard is initialized, it waits for the VBL signal to start processing. This is accomplished by the MouseCard’s firmware, which uses the Apple II's main CPU to monitor the VBL signal. The MouseCard also includes its own CPU, the 68705, which handles timing and interrupts.
The 68705 uses a timer to generate IRQs at specific intervals that match the VBL timing for different Apple II models. The timing values are calculated based on the hardware specifics and ensure that interrupts occur at the right moment, minimizing flicker in graphics.
For programmers, it’s important to use the MouseCard's firmware calls correctly to maintain synchronization across different Apple II models (NTSC and PAL), which may require measuring cycles or asking the user for their machine type.
In summary, the Apple II MouseCard effectively synchronizes its interrupts with the VBL signal, ensuring smooth graphics, and developers need to account for different machine types for optimal performance.

9.How Obama’s BlackBerry got secured (2013)(How Obama’s BlackBerry got secured (2013))
In January 2009, when Barack Obama became president, he faced the challenge of using his BlackBerry, which was seen as a security risk. Initially, he had to give up the device, but he eventually kept it after it was secured with special encryption software and additional security measures.
Previously, George W. Bush had to stop using his BlackBerry upon taking office due to security concerns and legal requirements. Obama wanted to stay connected with people outside the White House, so a collaboration between the Secret Service, the White House Communications Agency, and the NSA led to a solution.
While there were suggestions that Obama could use a secure device like the Sectéra Edge, it was impractical and bulky. Instead, a compromise was reached where Obama could use a modified BlackBerry with SecurVoice software for secure communications. This software was developed by The Genesis Key and allowed secure voice and data encryption.
Richard George from the NSA oversaw the process of securing Obama's BlackBerry, which involved extensive testing and modifications. The NSA ultimately chose the smartphone model for the president. The secured BlackBerry was delivered to Obama by mid-2009, and he had to change his email address to a secret one.
The secure BlackBerry was also given to a limited number of close contacts to facilitate encrypted communication. This meant that Obama's ability to communicate broadly was restricted.
Despite the security measures, risks remained, such as potential hacking and location tracking. To mitigate these risks, the BlackBerry was designed to prevent email forwarding and attachments, and Obama's contacts were advised on security protocols.
In conclusion, while Obama was able to keep using a BlackBerry, it required significant effort to ensure its security, marking a shift toward using software applications for secure communications on standard smartphones. As of 2023, the BlackBerry devices used by Obama are on display at the National Cryptologic Museum.
10.How linear regression works intuitively and how it leads to gradient descent(How linear regression works intuitively and how it leads to gradient descent)
Learning for computers involves improving guesses based on data. This post explains linear regression, which starts with an initial guess of house prices based on size and improves it using a method called gradient descent.
When looking at house prices, there’s a clear trend: larger homes usually cost more. By plotting house size against price, we can draw a line that represents this relationship. The line has a slope, indicating how much price increases with size (price-per-square-foot), and an intercept, which represents the starting price.
To find the best line for pricing your house, we need to measure how well it fits the data. This is done by calculating the "error"—the difference between predicted and actual prices. A good line minimizes these errors, and we can sum them up to find the line with the smallest total error.
However, measuring error can be tricky. One method is absolute error, which treats all mistakes equally, but it may overlook larger errors. A better approach is to use squared error, which penalizes bigger mistakes more severely, encouraging a more reliable line.
To find the best line with the smallest error, we can’t test every possibility due to the vast number of potential combinations of slope and intercept. Instead, we use gradient descent, which is a step-by-step method that adjusts the slope and intercept based on the error's steepness until we find the optimal line.
Gradient descent works best with squared errors because it creates a smooth curve that makes it easier to find the minimum error point. This technique is also foundational for training neural networks in deep learning, showing that the principles of linear regression apply broadly in machine learning.
In summary, the process of using linear regression and gradient descent helps us make accurate predictions for house prices based on size, allowing for informed and trustworthy pricing decisions.

12.Will protein design tools solve the snake antivenom shortage?(Will protein design tools solve the snake antivenom shortage?)
The article discusses the potential of protein design tools to address the shortage of snake antivenom. It highlights several key issues:
-
Antivenom Production Challenges: The process of making antivenom is complicated and costly, which has led to a significant shortage. Snake bites kill between 81,000 and 138,000 people annually, and many more suffer permanent injuries. The high cost of antivenom, particularly in low-income regions, exacerbates the problem.
-
Heterogeneity of Snake Venom: Snake venom varies widely between families, species, and even individual snakes. This complexity makes it difficult to create a universal antivenom, as different venoms require different treatments.
-
Current Antivenom Methods: Traditional antivenom is produced by injecting snakes' venom into animals (like horses or sheep) that then produce antibodies, which are harvested and purified. This method is not only slow but also limited by the variety of venoms and the ability of animals to generate the necessary antibodies.
-
Potential of Computational Tools: Recent advancements in protein design, such as the work from the Baker Lab using computational tools to create proteins that bind to specific venom components, may offer a way to develop more effective antivenoms. However, this research alone doesn't solve the broader issues of venom diversity and production challenges.
-
Economic Considerations: Even if a universal antivenom is developed, the market dynamics remain challenging. Antivenoms primarily serve low-income populations in developing countries, making it hard to justify large investments in production.
-
Future Outlook: There's potential for new methods, including cell-based production of antivenoms, to improve the situation. However, significant financial backing and market confidence are needed to make these innovations viable.
The article concludes that while protein design tools could lead to better antivenoms, overcoming economic and production hurdles is crucial for solving the antivenom shortage issue.

23.Trump's NIH Axed Research Grants Even After a Judge Blocked the Cuts(Trump's NIH Axed Research Grants Even After a Judge Blocked the Cuts)
Protesters recently gathered on the National Mall to urge the Trump administration to halt cuts to federal government funding. In a related issue, internal records reveal that the Trump Administration, despite a court order, terminated over 600 research grants from the National Institutes of Health (NIH), including those focused on transgender research. This was allegedly in response to executive orders from President Trump.
The Washington state attorney general's lawsuit highlights that the NIH's actions contradict the administration's claims of compliance with the court's injunction. Documents show that the NIH cut funding for grants deemed to promote "gender ideology" shortly after the injunction was issued. Whistleblower testimonies indicate that the Department of Government Efficiency (DOGE) played a significant role in directing these terminations, despite the administration's claims of limited authority.
The lawsuit also reveals that the administration has been opaque about its reasons for terminating grants, which often focus on politically sensitive topics like gender identity and climate change. Critics argue that these cuts undermine scientific research and align more with political agendas than with public health priorities. The ongoing legal battle seeks to clarify the administration's compliance with court orders and the true motivations behind the grant terminations.
24.Engineered adipocytes implantation suppresses tumor progression in cancer models(Engineered adipocytes implantation suppresses tumor progression in cancer models)

47.How to Average in Prolog (2017)(How to Average in Prolog (2017))
The text discusses how to calculate the average of a list of numbers using Prolog programming. The author presents two methods:
-
Directly averaging a list - This involves defining a function that calculates the average by finding the sum of the list and dividing it by the number of elements.
-
Using a procedural approach - A more complicated method is shown, where the average is computed using recursion. This involves creating additional predicates and managing state variables, which makes the code longer and more complex.
The author expresses frustration with the requirement to avoid using Prolog's standard library, suggesting that this makes the code unnecessarily complicated and less readable. The main points are:
- Prolog allows for concise and clear code, but students are often restricted from using it.
- Procedural loops can be transformed into recursive functions in Prolog, but this can lead to convoluted code.

48.I can’t understand Apple’s Critical Alert policy (2023)(I can’t understand Apple’s Critical Alert policy (2023))
The author launched an iOS app called SuperDose, designed to remind users to take their medications. To work effectively, the app needs access to Apple's Critical Alerts API, which allows notifications to bypass silent mode and Do Not Disturb settings—important for users with life-saving medication needs.
Despite the Health app using Critical Alerts for similar purposes, the author’s request for access was denied. The rejection cited that apps unable to enforce proper usage aren't suitable candidates, which the author finds illogical since Critical Alerts require user consent. They are frustrated because some less urgent apps have received approval for Critical Alerts, while their app, which addresses a critical need, has not.
Without access to this API, the app risks users missing important medication reminders, potentially putting their health at risk.
49.Ancient DNA from the green Sahara reveals ancestral North African lineage(Ancient DNA from the green Sahara reveals ancestral North African lineage)
This article discusses findings from ancient DNA discovered in the Takarkori rock shelter in southwestern Libya, dating back about 7,000 years. During the African Humid Period (AHP), the Sahara was a green savannah, which supported human habitation and pastoralism. The DNA analysis reveals that the individuals from Takarkori belonged to a previously unknown North African lineage that diverged from sub-Saharan African lineages around the same time modern humans left Africa.
These Takarkori individuals are closely related to ancient foragers from Morocco but show limited genetic exchange with sub-Saharan populations during the AHP. Notably, they have significantly less Neanderthal ancestry compared to other ancient populations from outside Africa. The study suggests that the spread of pastoralism in the Sahara was primarily due to cultural exchange rather than large-scale migration.
Overall, the findings provide insights into the genetic history of North Africa, highlighting an isolated lineage that existed before the influence of farming groups from Europe and the Levant. This research enhances our understanding of human settlement and adaptation in the Sahara during a time when it was much more hospitable than it is today.

61.Cuttlefish 'talk' with their arms, study reveals(Cuttlefish 'talk' with their arms, study reveals)
Researchers have found that cuttlefish communicate using specific arm movements, referred to as "arm wave signs." A study conducted by scientists from École Normale Supérieure in Paris and the Italian Institute of Technology identified four distinct gestures:
- Up sign - Arms extend upward and outward.
- Side sign - Arms are rolled to one side.
- Roll sign - Arms are tucked and rolled under the head.
- Crown sign - Arms form a crown-like shape with rapid movements.
These gestures are part of a complex communication system that can be perceived visually and through vibrations in water. Cuttlefish respond differently to these signals based on their orientation, indicating they process these movements similarly to how humans perceive faces.
The study also showed that cuttlefish can detect meaningful information from water vibrations, suggesting a dual-channel communication system. This discovery highlights the sophistication of cuttlefish interactions and opens new avenues for understanding communication in marine life. Researchers hope to further explore how different animal species communicate with their environments.

68.Telling Lies: Bowie and Online Music Distribution in 1996(Telling Lies: Bowie and Online Music Distribution in 1996)
In 1996, online music retail was growing, but downloading and streaming music were still challenging. David Bowie attempted to change this by releasing his single "Telling Lies" as a free download on his website, with the help of the company N2K, aiming to bypass traditional record labels.
At the time, music was primarily sold on CDs through online retailers, not as digital downloads. The technology for high-quality music downloads was limited, and many users faced slow download speeds and poor audio quality. Despite these issues, Bowie's release attracted significant attention, with 450,000 downloads in the first week.
Bowie viewed this experiment positively, although he acknowledged that the idea originated from Virgin Records. He was excited about the potential of the internet but recognized that the technology was still in its early stages. N2K's CEO, Larry Rosen, believed this experiment signaled a major shift in how music would be distributed electronically in the future.
69.Hyper-Typing(Hyper-Typing)
The article discusses a trade-off in TypeScript's type system: stricter types provide more safety but can become overly complex. This complexity leads to a phenomenon called "hyper-typing," where libraries aim for perfect type safety but end up with confusing types and error messages.
The author illustrates this with a function example, showing how looser types can be simpler and easier to use, while stricter types, although safe, add complexity. They mention TanStack Form, a library that emphasizes type safety but results in complicated type definitions that can be hard to understand.
The drawbacks of hyper-typing include:
- Poorly formatted type definitions that are difficult to read.
- Complex types that are hard to grasp.
- Unsafe workarounds where developers resort to using
any
to bypass type issues. - Confusing error messages that arise from complex types.
The author concludes that they prefer simpler, less strict libraries that are more enjoyable to work with, or using type generation from schemas, which can lead to better developer experiences.

86.Accents in latent spaces: How AI hears accent strength in English(Accents in latent spaces: How AI hears accent strength in English)
BoldVoice is an AI-powered app designed to help non-native English speakers improve their accents. The app uses a unique concept called the "accent fingerprint," which analyzes speech recordings to understand accent strength.
To visualize accents, BoldVoice creates a "latent space" using audio samples from various speakers. In this space, accents are plotted based on how closely they resemble native English accents. For example, the app compared the recordings of Victor, a non-native speaker with a strong Chinese accent, to Eliza, a native American English speaker.
Key findings from their research include:
- Accent Strength Measurement: The model accurately assesses how strong a person's accent is, regardless of their native language.
- Accent Improvement: With practice and technology, speakers can modify their accents. For instance, Victor was able to improve his accent significantly after practicing with a modified recording of Eliza's voice.
- Background Noise: Reducing background noise in recordings does not significantly change the measured accent strength.
- Voice Conversion: The app can convert a speaker's voice to match a target accent, aiding in practice.
The technology has potential applications in tracking language learner progress, evaluating speech recognition systems, and monitoring speech synthesis for accent consistency. BoldVoice plans to explore more about accents in future posts.

88.All of the Biggest U.S. Cities Are Sinking(All of the Biggest U.S. Cities Are Sinking)
A recent study has found that all 28 of the largest U.S. cities are experiencing land subsidence, meaning they are sinking to varying degrees. This affects not only coastal cities but also those further inland. The study, published in Nature Cities, reveals that some areas within these cities are sinking faster than others, which could lead to structural problems for buildings and infrastructure.
The primary cause of this sinking is the extraction of groundwater, which accounts for about 80% of the subsidence. Other factors, such as the weight of buildings and natural geological processes, also contribute. For example, Houston is the fastest-sinking city, with significant areas sinking more than 5 millimeters per year.
The researchers highlighted that population growth and climate-induced droughts could worsen the situation. They also noted that some cities experience uneven sinking, which can cause tilting and stress on buildings. While only 1% of the land area in these cities is affected by differential sinking, it still poses risks, especially in densely populated urban areas.
The study suggests that cities should take action to address these issues, such as improving drainage systems and retrofitting buildings to handle potential subsidence. The goal is to move toward solutions that mitigate the impacts of this problem.
