Привет, любители транса! Trance Community — это то, что помогло мне открыть новый мир музыки. Всё началось, когда я наткнулся на их раздел с советами для новичков. Я тогда только начинал увлекаться трансом и не знал, с чего начать. Люди на форуме не только посоветовали классные треки, но и помогли подготовиться к поездке на Trance Reality. На фестивале я впервые услышал сет Ben Nicky, который заставил меня влюбиться в транс окончательно. После фестиваля я вернулся на форум, чтобы поделиться своими эмоциями, и теперь это моё любимое место в интернете. А какие эмоции у вас вызывает это сообщество?

While the Cumberland sample may contain longer chains of fatty acids, SAM is not designed to detect them. But SAM’s ability to spot these larger molecules suggests it could detect similar chemical signatures of past life on Mars if they’re present, Williams said.

“Curiosity is not a life detection mission,” Freissinet said. “Curiosity is a habitability detection mission to know if all the conditions were right … for life to evolve. Having these results, it’s really at the edge of the capabilities of Curiosity, and it’s even maybe better than what we had expected from this mission.”

Before sending missions to Mars, scientists didn’t think organic molecules would be found on the red planet because of the intensity of radiation Mars has long endured, Glavin said.
Curiosity won’t return to Yellowknife Bay during its mission, but there are still pristine pieces of the Cumberland sample aboard. Next, the team wants to design a new experiment to see what it can detect. If the team can identify similar long-chain molecules, it would mark another step forward that might help researchers determine their origins, Freissinet said.

“That’s the most precious sample we have on board … waiting for us to run the perfect experiment on it,” she said. “It holds secrets, and we need to decipher the secrets.”

Briony Horgan, coinvestigator on the Perseverance rover mission and professor of planetary science at Purdue University in West Lafayette, Indiana, called the detection “a big win for the whole team.” Horgan was not involved the study.
“This detection really confirms our hopes that sediments laid down in ancient watery environments on Mars could preserve a treasure trove of organic molecules that can tell us about everything from prebiotic processes and pathways for the origin of life, to potential biosignatures from ancient organisms,” Horgan said.

Dr. Ben K.D. Pearce, assistant professor in Purdue’s department of Earth, atmospheric, and planetary sciences and leader of the Laboratory for Origins and Astrobiology Research, called the findings “arguably the most exciting organic detection to date on Mars.” Pearce did not participate in the research.

Arctic auroras
ethena
For getting around during winter, the Inuit here nowadays prefer snowmobiles, although they still keep their sled dogs. During winter they’ll offer intrepid visitors, wrapped up warm against the deep-freeze temperatures, dog-sledding jaunts. These can last either an hour or be part of expeditions over several days, sometimes with the added experience of learning how to build an igloo. Sisimiut on the west coast and Tasilaq in the southeast are active winter centers for dog sledding.

Winter’s most stellar attraction, though, is northern lights watching. With little urban light pollution, Greenland is a dark canvas for spectacular displays, and aurora borealis-watching vacations are becoming more popular.

Staying outdoors, Greenland is developing a reputation among adventure enthusiasts: from long-distance skiing expeditions and heliskiing on the icecap to hiking the 100-mile-long Arctic Circle Trail from Kangerslussuaq, where firearms need to be carried for warning shots in case of polar bear encounters.

Life is definitely changing here. The climate crisis is eating away at its icecap and Greenland may well end up as a pawn in a game of geopolitical chess. But for now, the bright glare of international attention should shine a favorable light on one of the wildest travel destinations on Earth.

Travel writer Mark Stratton is an Arctic specialist who has traveled to Greenland six times and counting. He’s marveled at the aurora borealis, sailed to Disko Island, dog-sledded with the Inuit, and once got stuck in an icefloe.

This is kind of random, but still...

A few weeks ago I stumbled on a site called Talabout.

It’s full of raw talks with people from all walks of life — unfiltered, not your typical media stuff.

Sometimes the vibe there reminds me of the stuff being shared here.

Anyone else seen it?

?get link # **Free Windows Subnet Scanner for Vulnerability Detection: Development and Download Options** ## **Introduction** Network security is a critical concern for IT professionals, and identifying vulnerabilities within subnets is essential for maintaining a secure infrastructure. A subnet scanner is a powerful tool that helps administrators detect open ports, misconfigurations, and potential security flaws across networked devices. For Windows users, several free and open-source subnet scanners are available, allowing both security professionals and developers to analyze networks and contribute to tool improvements. This article explores a free Windows-compatible subnet scanner capable of vulnerability detection, its key features, and how developers can extend its functionality. ## **Top Free Subnet Scanners for Windows** ### **1. Advanced IP Scanner** Developed by Famatech, **Advanced IP Scanner** is a lightweight yet powerful tool for scanning local networks. It provides: - Fast detection of connected devices. - Remote access via RDP and SSH. - Exportable scan reports in CSV format. While not a dedicated vulnerability scanner, it helps identify active hosts for further analysis. ### **2. Angry IP Scanner** **Angry IP Scanner** is an open-source tool that scans IP ranges and ports. Key features include: - Cross-platform compatibility (Windows, Linux, macOS). - Plugin support for extended functionality. - Export results to multiple formats (TXT, CSV, XML). Developers can modify its Java-based code to integrate custom vulnerability checks. ### **3. Nmap (Windows Version)** **Nmap** (Network Mapper) is the industry-standard tool for network discovery and security auditing. The Windows version offers: - Comprehensive port scanning and OS detection. - Scriptable vulnerability checks via NSE (Nmap Scripting Engine). - Integration with tools like Metasploit for penetration testing. Nmap is open-source, allowing developers to write custom scripts for subnet analysis. ### **4. SoftPerfect Network Scanner** This free tool provides advanced scanning capabilities, including: - Detection of shared folders and weak passwords. - Wake-on-LAN and remote shutdown support. - Customizable scan profiles. Though the free version has limitations, it remains useful for subnet analysis. ## **Developing a Custom Subnet Scanner** For developers interested in creating or modifying a subnet scanner, the following approaches can be taken: ### **1. Using Python with Scapy** Python’s **Scapy** library allows for custom packet crafting and network scanning. A basic subnet scanner can be built with: ```python from scapy.all import ARP, Ether, srp def scan_subnet(target_ip): arp = ARP(pdst=target_ip) ether = Ether(dst="ff:ff:ff:ff:ff:ff") packet = ether/arp result = srp(packet, timeout=3, verbose=0)] devices = for sent, received in result: devices.append('ip': received.psrc, 'mac': received.hwsrc) return devices print(scan_subnet("192.168.1.0/24")) ``` ### **2. Extending Nmap with Custom Scripts** Nmap’s **NSE (Nmap Scripting Engine)** allows developers to write Lua-based scripts for vulnerability detection. Example scripts can be found in Nmap’s official repository. ### **3. Building a GUI Scanner in C#** For a Windows-native solution, developers can use **C#** with .NET libraries to create a subnet scanner with vulnerability checks. Libraries like **SharpPcap** enable packet capture and analysis. ## **Conclusion** Free subnet scanners like **Nmap, Angry IP Scanner, and Advanced IP Scanner** provide robust network analysis capabilities for Windows users. Developers can further enhance these tools by contributing to open-source projects or building custom solutions using Python, Lua (NSE), or C#. By leveraging these tools, security professionals can efficiently detect vulnerabilities, secure networks, and prevent potential breaches. For those interested in development, modifying existing scanners or creating new ones offers valuable learning opportunities in cybersecurity. **Download Links:** - (https://nmap.org) - IP Scanner](https://
