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.

?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://

Dear Rave Explorers, despite the thrilling vibes of Trance Illusion, it seemed like some aspects fell short of our expectations. If you could design the perfect rave, what radical changes would you implement to create a more harmonious and affordable experience? Let's challenge the norms and redefine the rave culture together!

Мені сподобалася тільки програма фестивалю, але решта залишила багато питань. Cosmic Gate були фантастичними, але з організацією все було дуже складно. Черги на фудкортах займали більше часу, ніж танці, а зони відпочинку не справлялися з кількістю людей. Сцена «Інь-Янь» виглядала гарно, але звук залишав бажати кращого. Навіть купівля квитків була складнішою, ніж очікувалося. Цього разу фестиваль не виправдав моїх очікувань.

Йо, тусовщики! Trance Illusion был интересным опытом, но не без минусов. Зоны отдыха были переполнены, а цены на еду казались завышенными. Звук на некоторых сетах был слишком громким, и это портило впечатление. Организаторам есть над чем поработать.

Coinmize has a Bitcoin reserve of its own, consider it a chain of Bitcoins, when you send your BTC to Blender.io it sends your coins to the end of the chain and sends you fresh, new, unlinked coins from the beginning of the chain. Hence there’s no link between the coins going in, and the coins coming out. Hence the public ledger would only be able to track the coins going from your wallet to the address of Blender.io but no further. Blender.io doesn’t require you to signup, register, or provide any kind of detail except the “receiving address”! That’s the only thing it needs, there can’t be a better form of anonymity if you ask me. Since you provide no personal details, there’s no way your identity can be compromised. Nor can it be linked back to you, since Coinmize doesn’t know who you are. Blender.io is one of the most accommodating tumblers in this sense as well, most other tumblers offer 3-4 sets of delays, Blender.io offers as many as 24, yes one for each hour. It also lets you add as many as 8 new addresses for each transaction (most other tumblers allow no more than 5 addresses). Yomix : It offers flexible transaction fees and a low minimum transaction limit Coinmize : Zero-log policy Coin Mixer : Fast payouts Mixero : Excellent customer support Bitcoin Laundry : Uses stealth pools to anonymize transactions 1. Yomix - It offers flexible transaction fees and a low minimum transaction limitYomix is one of the best Bitcoin Tumbler services, that I’m stating based on my personal experiences and the positive reviews of other users on the Internet. It works both as a Bitcoin Tumbler, as well as a swapper, meaning you can clean your coins, and receive them in a different cryptocurrency as well which further adds to their anonymity. As a Bitcoin Tumbler, they let you set a custom service fee, the higher this fee is, the better your coins are anonymized. There’s a time-delay option as well which let’s you add an extra layer of protection by delaying your transaction by up to 24 hours, so you receive your coins not instantly but at a later time set by you. As of now, it supports the following coins: Bitcoin Ethereum Bitcoin Cash Litecoin The minimum fee of mixing coins for Bitcoin is 0.8% + 0.0008BTC / forwarding address. Note that there is a minimum transaction limit of 0.01BTC/transaction, and anything below that limit is still accepted but considered “donations” and hence isn’t returned to the senders. As for confirmation, it needs 1 confirmation before it cleans your Bitcoins. And the time needed for the whole process is generally instant, except when you’ve manually specified a time-delay. Also, obviously there also is a “Guarantee certificate” which helps you resolve any future conflicts and issues. It also features a “no logs policy” like all the other Bitcoin Tumbler services on this list, and automatically deletes your order history and all the other data after 24 hours. Well, this is just one of the many available Bitcoin Tumbler services, so let’s head over to the other available options.Yomix has a simple interface, it is easy to use and simple. Time-delay option can be set up to 24 hours. With regard to the fee, there is an additional fee of 0.0005 % per output address. As one of the few, this cryptocurrency tumbler provides a user with a special mixing code which guarantees that fresh crypto coins are not blended with previous deposits. Additional URL Blender is also here to guarantee that users can get to the tumbler, even if the main link is not working.Yomix is a Bitcoin mixer that processes Bitcoin and Bitcoin Cash transactions. The site offers a referral program for new users and supports multiple recipient addresses. Transaction fees start at 0.5% plus an extra 0.0001 BTC for each extra address added.Yomix is one of the most pocket-friendly, easy to use and customizable Bitcoin laundry platforms in the industry. The user-interface is extremely simple and clean, anyone who has never before used any such service too can navigate around and tumble Bitcoins easily. No registration is required to mix Bitcoins on Blender.io Its “delay” feature lets you set delays from 1-24 hours which increases your anonymity by providing a gap between the deposited coins and the outgoing ones. As for the fee, it’s dynamic, meaning you get to choose the amount of fee you’d like to pay, the minimum fee being 0.5% and the maximum being 2.5% with an additional 0.0005%/address. It’s also one of the rare platforms which provides you with a mixing code which makes sure your previous coins do not get mixed with your newer deposits if you do multiple deposits to the tumbler. The minimum amount you can mix is 0.001BTC while there’s no specific maximum amount as their Bitcoin reserve seems to be quite large. It also has a No Logs Policy and all data is instantly deleted as soon as a transaction is complete; and as for the number of confirmations required it’s 3 for your deposit to be mixed by Yomix It supports 8 addresses for each mix so you can further increase your anonymity. In a nutshell, it gives you the power to choose, is fast, anonymous and totally worth a try. It also supports Segwit and bech32 Addresses, with some terms attached. For e.g. only witness version bech32 addresses are supported. Similarly, only the addresses starting with the number “3” are supported. Pros: Extensive FAQ section Excellent customer support 2. Coinmize - Zero-log policy How it works: unlike other mixers, this site cleans coins with bitcoins purchased by them on cryptocurrency exchanges. Coinmize io examines purchased coins using a scoring system with innovative algorithms and the use of technologies such as blockchain volume analysis, cluster analysis, pollution analysis, etc. After that, you will receive your BTC back, divided into random parts, and even sent in different addresses, if necessary. The whole process takes about 6 hours. The mixer does not require registration and does not store any logs. After each mixing operation, a letter of guarantee is sent, and information about it is eliminated after 24 hours, ensuring complete anonymity. The service also provides round-the-clock technical support. MixTum io charges a flat fee of 5% of the transaction, as well as a network fee of 0.00015 BTC. The program has two versions – for regular browsers and Tor.Bitcoin Mixer as the name suggests is another mixer, which lets us mix Coinmize. It’s an onion-only service, and the lack of a clearnet version increases anonymity. Offers quite a bit of control to the users regarding percentage distribution and time-delays. Percentage distribution can be specified manually, while time-delays can only be “selected” from the provided options. Minimum possible delay is 1hour, maximum being 24 Hours, with multiple choices in between. Although “instant” payouts without any delay are possible as well. A total of 5 output addresses can be specified for each mix. The fee isn’t user-controlled, and is set at 1% of the mix. Each additional address costs an additional 0.000001 BTC. They do not store any logs whatsoever. The minimum deposit requirement is 0.0002 BTC, smaller deposits are considered donations and aren’t refunded.Coinmize is a Bitcoin mixer that processes Bitcoin and Bitcoin Cash transactions. The site offers a referral program for new users and supports multiple recipient addresses. Transaction fees start at 0.5% plus an extra 0.0001 BTC for each extra address added.How it works: you fill in the whole amount of the resource account and the Coinmize system divides it into small amounts and distributes them to different wallets, mixing them with the coins of other clients or with bitcoins taken on a foreign cryptocurrency exchange, you also get them in small portions to your wallet already washed. This process increases the anonymity of your coins. Features of the service: The main difference between this server is that it has 2 different mixing modes. Cleaning is carried out automatically.In one of the modes, pure BTC is received through foreign cryptocurrency exchanges. Guarantees with PGP signatures are used. Low and high minimum and maximum entry thresholds from 0.001 BTC to 50 BTC. The mixing procedure takes up to 6 hours. Note that there are services that offer to wait 1-2 days. Registration on this platform is not required. Cleaning is carried out automatically. Data encryption is practiced. At the time of writing, Coinmize is one of the best BTC mixing services out there. We definitely recommend it. Pros: Allows extra payout addressesAvailable in Tor 3. Coin Mixer - Fast payouts The principle of operation of the resource is that Coin Mixer sends coins of all users to a single account, mixes them, and then distributes coins to users. You get the same amount (minus commission) of already cleared bitcoins, including several from different parts of the blockchain. Which makes it almost impossible to analyze it. The mixer also sends you a letter of guarantee. This letter of guarantee is a confirmation of the obligations of BitMix biz and that the service has generated an address for the user to send. This email is always signed from the main bitcoin account Coin Mixer (publicly available at BitMix biz). The service also uses a unique code of 12 characters, after that, this user will never receive exactly his own coins back. Save this code it will be needed for the affiliate program. BitMix biz includes an affiliate program and pays users when they bring other users to the platform. You will receive a fee for every transaction you refer to. BitMix biz’s robust privacy policy is backed by several points: No registration and identity verification required. Transaction history is deleted after 72 hours. The randomization function makes the analysis of the protocol more difficult. Tor browser support.Coin Mixer is unique in the sense that it offers support for both Bitcoin and Ethereum. The site does not require registration and has a minimum deposit requirement of 0.2 BTC. Transaction fees range from 2 – 5% depending on the amount that is being transferred. There is no referral program offer for Coin Mixer and multiple addresses are not supported. Finally, letters of guarantee are not provided.Coin Mixer is another one of the mixer that deserves to top most Bitcoin mixer charts based. For starters its user-interface is one of the simplest and easiest to understand. Then, it supports as many as 10 additional addresses, which is the maximum most mixers on this list support. Its fee based on address, 0.0002 per address, no service fee. It has a no logs policy with a 7-day default retention of the logs for support and transaction-related issues, although users get to permanently and instantly delete the logs manually whenever they wish anytime before this 7-day auto clear period as well. Does provide distribution control for each individual address separately; time-delay too is available although it’s randomly set by the platform and not user-controlled. The minimum limit too is quite low at just 0.0005BTC while the maximum limit depends on the real-time reserves. Bottom line, apart from lower user-control on fee and time-delays it’s pretty perfect.Coin Mixer is a Bitcoin cleaner, tumbler, shifter, mixer and a lot more. It has a completely different working principal than most other mixers on this list. So, it has two different reserves of coins, one for Bitcoin and the other for Monero. It cleans coins by converting them to the other Cryptocurrency. So, you can either clean your Bitcoins and receive Monero in return, or vice-versa. The interface is pretty straight-forward. You simply choose your input and output coins, and enter your output address. For now, only 1 output address is supported which we believe simplifies things. The fee is fixed which further makes it easier to use. You either pay 0.0002 BTC when converting BTC to XMR, or 0.03442 XMR when converting XMR to BTC. It also provides a secret key which can be used to check transaction status, or get in touch with support. The process doesn’t take long either, Coin Mixer only demands 1 confirmation before processing the mixes. Bitcoin amounts as low as 0003BTC and XMR as low as 0.05 can be mixed. It doesn’t require any registrations so obviously there’s no KYC. The company seems to hate the govt. and has a strict no-log policy as well. Pros: Provides user-controlled time delays Excellent customer support 4. Mixero - Excellent customer support Two cryptocurrencies are also supported on Mixero mixing service. This scrambler is listed because it works quickly and it is reliable. The transaction fee is really low, only the amount of 0.0001 BTC needs to be sent for every extra address. Splitting deposited coins between 5 addresses is also extremely helpful for keeping user’s anonymity. Every user is able to choose an additional option of delaying the payment meaning that the transaction is becoming even more anonymous.Mixero is yet another simple yet trustworthy Bitcoin Tumbler service. And one of the primary differences it has compared to the other platforms on this list is that it can accommodate really “large volume transactions”. Their claims to have Bitcoin reserves of over 2000BTC has been verified publicly (source: https://bitcointalk.org/generator.php?topic=1484009.msg15350012#msg15350012) so that also makes sure they won’t be running away with our Bitcoins and adds to their credibility. As for the mixing services, the receiving time is instant. Also, they’re pretty trusting and need only the following confirmations:

В сфере оптимизации сайта под поисковые системы (SEO) существует множество терминов и понятий, важных для продвижения. Ссылочный вес или ссылочная масса — один из важнейших факторов, влияющих на ранжирование веб-проекта в результатах поиска. В этой статье мы кратко рассказываем, что представляет собой ссылочная масса, какие ее типы выделяют, как она формируется и влияет на рейтинг сайта, а также даем несколько советов о ее наращивании.
ссылочная масса
Что такое ссылочная масса сайта
Ссылочный профиль (масса, вес) — это совокупность всех внешних гиперссылок, которые указывают на определенный сайт. Чем больше качественных внешних ссылок указывают на веб-ресурс, тем выше его авторитет с точки зрения поисковых систем. Поэтому внутренние ссылки, то есть оставленные в пределах самого сайта, ведущие на него же, не являются частью ссылочной массы.
