SolarSquare, an Indian rooftop solar provider, is negotiating a Series C round that could bring in $55-60M at a $450-$500M valuation. The company has already installed over 150 MW of capacity across 29 cities and aims to reach 200 MW this year. This funding will accelerate growth in India's booming residential solar market, which is set to contribute more than half of the country’s renewable energy by 2030.
Apple and Google have introduced robust security measures against government-sponsored hackers targeting journalists, activists, and critics with advanced spyware. These tools, such as Apple's Lockdown Mode and Google's Advanced Protection Program, aim to protect users by limiting device functionality but enhancing security features like blocking attachments in iMessage or restricting web technologies in Safari. If you're a journalist or human rights defender, these new defenses are crucial for safeguarding your data from state surveillance. For instance, since March 2023, Apple has never detected a successful attack on an iPhone with Lockdown Mode enabled. Let's dive deeper…

Summary: SolarSquare secures up to $60M at a valuation of up to $500M for its Series C round. This investment will fuel India's growing residential solar market, aiming for over 50% of the country’s renewable energy by 2030.
Key Points:
SolarSquare is in advanced talks to raise between $55 million and $60 million at a valuation of up to $500 million.
The company has installed more than 150 megawatts of solar capacity across 29 cities in nine states, powering nearly 50,000 homes.
SolarSquare's residential segment now accounts for the majority of its business and aims to reach 200 MW this year.
India’s cumulative installed solar capacity has surged from about 3 GW in 2014 to more than 150 GW by 2026, making it the third-largest producer globally.
The country's goal is to achieve over half of its renewable energy capacity from solar power by 2030.
Why it matters: SolarSquare's Series C funding will accelerate India’s residential solar market growth. With a target of more than half of the country’s renewable energy coming from solar by 2030, this investment is crucial for achieving these ambitious goals.

Summary: Apple and Google have rolled out enhanced security features to protect against government spyware. If you're at risk of targeted attacks, these tools could be your first line of defense.
Key Points:
Apple's Lockdown Mode blocks attachments in iMessage and restricts web technologies like JavaScript in Safari when enabled (March 2023).
Google’s Advanced Protection Program includes Deep Gmail Scans and Safe Browsing in Chrome, enhancing account resilience against hackers since 2017.
Lockdown Mode changes device functionality to prevent spyware from accessing data or tracking users' real-time locations on Apple devices (March 2023).
Google's Advanced Protection Mode blocks connections to 2G networks and locks the device if it detects suspicious activity, adding another layer of security for Android users.
Both programs offer features like Google Play Protect and Memory Tagging Extension (MTE) to safeguard against unwanted messages and harmful links sent via Messages app.
Why it matters: If you're a journalist or human rights defender using an iPhone with Lockdown Mode, your data is now better protected from sophisticated spyware attacks. Since March 2023, Apple has never detected a successful attack on iPhones with this feature enabled. For Android users, Google's Advanced Protection Program offers similar defenses against malicious hackers of all kinds.

Summary: Roger Linn's LinnStrument introduced MPE in 2014, three years before it became an official standard — a must-have for expressive musicians.
Key Points:
LinnStrument was the first instrument to implement MIDI polyphonic expression (MPE) in 2014.
The Association of Musical Electronics Industry (AMEI) officially released MPE as a standard in 2017, three years after LinnStrument's release.
J Dilla's MPC 3000 is now part of the Smithsonian collection, highlighting its cultural impact.
VR headsets like Meta Quest 3 and Apple Vision Pro are currently the favorite gadgets among tech enthusiasts.
Rhino3D is the first app installed on new phones or computers for many users.
Why it matters: If you're a musician looking to add depth and nuance to your performances, LinnStrument's early adoption of MPE means you can start using advanced features now. The instrument has become essential for producers and composers who want precise control over their music.

Summary: Deep Fission seeks $157M in a Nasdaq IPO at $24-$26 per share. Despite raising funds, the company's reactor timeline has slipped and it’s losing money.
Key Points:
Deep Fission is seeking up to $157 million through an IPO on Nasdaq with shares priced between $24 and $26 each.
The company raised $30 million in a private placement at $3 per share following its reverse merger with Surfside Acquisition in September 2023.
Deep Fission's deficit grew to $88.1 million by March, up from $56.2 million previously, indicating financial struggles despite fundraising efforts.
The company is drilling test wells and aims for a well depth of up to 6,000 feet as part of its commercial-scale reactor plans.
Deep Fission's timeline for achieving criticality in its first reactor has slipped; it no longer provides an estimated date.
Why it matters: Deep Fission's IPO attempt signals a significant financial challenge despite raising $30 million. The company’s deficit grew to $88.1 million by March, and its timeline for achieving criticality in its first reactor has slipped without providing an estimate. This affects investors and stakeholders who must weigh the risks of backing a nuclear startup with uncertain technical progress.

Summary: xAI is spending $2.8 billion on natural gas turbines, a move that contrasts with SpaceX's vision for space-based solar power. Why it matters: It highlights the challenges in transitioning to clean energy in tech.
Key Points:
xAI plans to buy $2.8 billion worth of unregulated natural gas turbines to power its data centers.
SpaceX spent $131 million on 1,279 Cybertrucks for various projects, including potential space applications.
xAI has invested $697 million in Tesla Megapacks over the past two years for grid-scale battery storage.
Solar energy is not a significant source of power for xAI's current data centers despite SpaceX’s ambitious plans.
Space-based solar arrays can generate more than five times the energy terrestrial ones due to 24/7 illumination.
Why it matters: xAI's decision to invest in natural gas turbines raises critical questions about sustainable computing. For companies like Tesla, which aim for a solar electric economy, this move by xAI highlights the ongoing tension between technological advancement and environmental responsibility. The reliance on fossil fuels could impact future regulatory scrutiny and public perception of tech companies' commitment to sustainability.
