Yikes. If anybody ever adapted this to non public spectrum (restricted band) it could be used for naughty purposes 👿. Even in public it is scary accurate!

This year marks the 75th anniversary of the establishment of diplomatic relations between China and Pakistan. Through changing times, China-Pakistan friendship has remained as strong as iron, with the two countries often termed as "Iron Brothers", while green cooperation is becoming a new highlight of bilateral ties. Located on the Jhelum River in Pakistan, the 720 MW Karot Hydropower Project, developed by CTG and operated by CSAIL, is known as Pakistan's version of "Three Gorges Project". It is the first major CPEC hydropower project in commercial operation and the first large-scale hydropower investment project under the Belt and Road Initiative. With an average annual output of about 3.206 billion kWh, it can meet the electricity demand of more than five million local people. CSAIL also operates three wind farms in Jhimpir, Sindh, with a combined installed capacity of 148.5 MW. Together, they deliver about 443 GWh of clean electricity every year, enough to meet the power needs of more than 600,000 people. But this partnership is not only about electricity. Beyond power generation, CSAIL has supported biodiversity protection along the Jhelum River, community infrastructure, roads, bridges, water systems, hospitals, schools, scholarships and flood relief. From hydropower to wind power, from energy supply to community support, these projects show how clean energy cooperation can bring long-term value to people, nature and development.

🇺🇸 163 Years Ago Today, June 30th, 8:30 PM General John Buford holds a council with his brigade commanders. His scouts report Confederate forces to the west, and Buford correctly anticipates that the enemy will attack in force the next morning. "The enemy will attack us in the morning. They will come booming, skirmishers three deep. If we don’t hold this high ground until the infantry gets up, the road will be full of dead men." He stations signal officers in the cupola of the Lutheran Seminary to watch the western approaches. He also sends urgent messages to Major General John Reynolds, commander of the I Corps, urging him to bring his infantry forward as quickly as possible. Buford knows his cavalry cannot hold the position alone if the Confederates attack in strength the next morning. Note: The Gettysburg movie had him around the Lutheran Seminary a lot more than he was. He did most of his work from his headquarters at Eagle Hotel.

🇮🇱 Channel 14 reports the Israeli government may announce a settlement nucleus in Gaza before the elections, while demolitions roll on in southern Lebanon Laith Marouf comes at this from a position he states openly: he rejects Israel's legitimacy outright and describes it as a colonial project. His read on the settlement report cut against the panic: psychological warfare, he argued, over ground he claims three years of munitions have left unlivable, an announcement designed to break morale rather than break ground. His forecast runs darker than any other guest's. Eighteen months to two years of continuous escalation, in his telling, ending in what he insists is Israel's collapse, militarily or through courts, boycotts, and economic unraveling. On the Gulf, his claim is that Iran strikes only facilities used for American operations, that Qatar objected to its bases being used this round, and that Oman's fee revenue shows the sovereignty path he believes the region should take. There was real news between the fireworks: the Axios report that Trump told Netanyahu to pull out of Syria and south Lebanon, and fresh footage of a partially sunken bulk carrier near the strait.

October 3, 1982 SUMMERALL AND MADDEN CALL DIVISION-III COLLEGE FOOTBALL Wittenberg vs. Baldwin-Wallace During the fall of 1982, in the midst of the NFLPA's 57-day players' strike, CBS needed to get creative with their Sunday afternoon programming. So on October 3, the network sent Pat Summerall and John Madden to Springfield, Ohio to call Division-III Wittenberg's game against their rival Baldwin-Wallace — each school with an enrollment then of about 2,000 students. Three other #NFL on CBS broadcast teams called Division-III games that weekend as well. Both Wittenberg and Baldwin-Wallace, as well as the Ohio Athletic Conference, were paid $10,000 each for the game. The video includes the CBS open and pregame introduction by Pat and John, the first several minutes of the game, as well as some select highlights from this historic CBS broadcast. Certainly a very rare and fascinating broadcast — and I'm sure quite a thrill for those players, coaches, students, and communities.

Anna's Hummingbirds have been fooling humans for centuries with red throats. Those blazing crimson feathers that catch sunlight and seem to glow from within contain zero red pigment. The bird's gorget is built from microscopic transparent platelets stacked like glass slides, each one precisely 400 nanometers thick. When white light hits this biological interference filter, most wavelengths cancel each other out through destructive interference. Only red light at 630 nanometers survives the gauntlet and bounces back to your eye. The bird is essentially wearing a living hologram. Move your head three degrees to the left and the red vanishes completely. The angle change shifts which wavelength survives the interference pattern. The throat flickers between crimson, orange, deep purple, and invisible black as the bird moves through space. Every hummingbird species fine tuned their microscopic architecture to reflect different wavelength combinations. Anna's chose red. Allen's chose orange. Broad-tailed chose magenta. Each species evolved their own optical signature by growing feather structures at slightly different nanoscale dimensions. The precision required borders on impossible. These birds grow biological optical computers on their bodies. Each platelet must be manufactured to within a few nanometers of the target thickness or the color shifts completely. Human engineers struggle to build interference filters this precise in clean rooms with million dollar equipment. A hummingbird grows them while hanging upside down drinking sugar water. The evolutionary implications are staggering. Female hummingbirds are literally selecting mates based on their ability to grow functional nanophotonic devices. Males with better optical engineering get to reproduce. Sexual selection drove these birds to become living examples of advanced materials science. Your eye processes the reflected light as "red" but the bird's throat contains nothing red at all. The color exists purely in the interference between transparent surfaces and incoming photons. The hummingbird bent light itself into love.

Incredible enhanced and upscaled WWII footage shows the Fallschirmjäger (paratrooper branch of the German Luftwaffe) deploy an 88mm Flak 18 during street fighting in Italy in 1943. During World War II, Kurt Student served as the commander of the branch, holding the position due to his status as the second most senior officer in the Luftwaffe. During the German invasion of Crete, Allied forces and Cretan irregulars inflicted heavy losses on the Wehrmacht. In retaliation, Kurt Student ordered reprisals against civilians to deter the Cretan population from resisting German occupation. On June 2, 1941, German paratroopers arrived at the village of Kondomari, rounded up the male villagers, and selected their victims. Between twenty-three and sixty men were executed by a firing squad while the women and children of the village watched, witnessing what came to be known as the Massacre of Kondomari. As further reprisal against the Cretans the next day, the Fallschirmjäger killed 180 inhabitants in the village of Kandanos and razed the village to the ground.

Phase II/CP30/TU-01/ – TBM Kolli (S 81) Breakthrough at Otteri shaft Chennai Metro Rail Limited has commenced the expansion of the Chennai city’s metro rail network as part of Phase II after the successful completion of the Phase I and Phase I Extension. CMRL has ventured into an extensive infrastructure development in the city comprising of three more corridors of metro rail for a total length of 116.1 km. Corridor 3 comprising a total alignment length of 45.4 km from MadhavaramMilk colony to Siruseri Sipcot will be spanning across the north to south direction of the Chennai city and has a total of 28 underground stations and 19 elevated stations. Corridor 4 is an east west alignment for a length of 26.1 km connecting the beach front from Light House station to the Depot at Poonamallee has 9 underground stations and 18 elevated stations. Corridor 5 also begins at Madhavaram Milk colony and connects through Koyambedu, Porur, Alandur and other residential/commercial development of the city to Shollinganallur for a total length of 44.6 km with 6 underground stations and 39 elevated stations. The tunnel construction for the first 9 km underground section of Corridor 3 from Madhavaram Milk Colony to Kellys is being executed through M/s Tata Projects limited and mobilized 7 TBMs for the tunnelling works. The TBM Kolli (S 81) tunnel drive started on 11.07.2023 from AyanavaramStation to Otteri station (Up line), covered a bored tunnel length of 903 m and break-through done at Otteri shaft on 29.08.2024. This is the 6th TBM breakthrough carried out by M/s Tata Projects Limited under TU-01 contract. As a whole, CMRL has completed 7 TBM breakthroughs in phase-2 project. The tunnel section between Ayanavaram and Otteri is the most complex tunnel section under the contract TU-01 with major challenges, such as the TBM S 81 (Kolli) first 500m tunnel drive negotiated with sharp 220m radius curve and the last 200m tunnel drive with 280m radius curves. Also, this tunnel drive completed with major challenges such as passing through densely populated areas and addressing more than 100 No. of bore wells along the alignment by providing alternate sources without any issue to the public. The complete tunnel drive was well managed within the allowable minimum settlements and extensive instrumentation and monitoring was ensured throughout the drive. Thiru T. Archunan, Director Projects of CMRL, Thiru. Kolli Venkata Ramana, AGM CIVIL UG, Thiru. Alper Vahit Yildiz, Project Manager/Tata Projects, Thiru.

A poison ivy is one of the most notorious plants in North America, and for good reason. Hidden in forests, trails, and even backyards, it releases an oily irritant called urushiol that can trigger an intensely itchy, blistering rash within hours to days of contact, What makes it especially deceptive is how easily it blends into its surroundings, often going unnoticed until the reaction begins. Its classic identifier, “leaves of three,” is a helpful warning, but not a perfect one. The leaves can appear shiny or dull, smooth or slightly jagged, and shift in color from green to red or orange depending on the season. Poison ivy can grow as a climbing vine wrapping around trees or as a low shrub spreading across the ground, making it adaptable and easy to encounter in multiple environments. The real danger isn’t just touching the plant itself. Urushiol can linger on clothing, tools, pet fur, and other surfaces, meaning indirect exposure is just as risky. Immediate washing of skin, clothing, and any contaminated items is critical to reduce the severity of the reaction. In many cases, awareness and quick action are the differences between a minor irritation and days of relentless itching.

One of the patients that The Sameer Project had supported continuously was little Saadallah who sadly passed away last December from malnourishment. Eight months later, and in more dire times, his only brother is also malnourished. Help us support malnutrition cases: This mother had the pain of losing her baby, and now the stress and fear of seeing her older son suffer from the lack of food. The Sameer Project visited the now family of 3 to provide nutritional support. We gave a vegetable parcel for $114 including 10% bank transfer fees, tuna for $15 per can after 45% cash commission, and red and green nutritional suppliants ranging from $2.5-$12 each. And we will of course be back to supply this family with more as one visit does not help a child get out of the grips of malnutrition caused by a man-made famine. We miss Saadallah and will support his family who are still mourning his loss. Thank you for allowing us to assist through our Medical Campaign. Other ways to donate include: (Paypal option, please make sure to add a message saying "Medical") (Venmo option, please make sure to add a message saying "Medical")

These giant structures dotting the Central Valley are adjacent to impoverished communities and will not be placed into service for at least ten years, if ever. Delayed by construction traffic controls, local residents have a front row seat as they watch California’s misguided, High Speed Rail (HSR) project kick up dust and spend $ billions 💰 and $ billions 💰 of taxpayer dollars on unused overpasses that cross above roads, canals, rivers, and railways as Central Valley farming communities are divided by the fenced off HSR route. This particular structure crosses the in-service Amtrak line just south of Wasco. The existing line has been carrying passengers between Bakersfield and Northern California since 1899 when originally placed into service by Sante Fe Railroad. Today, Amtrak connects Bakersfield to Sacramento on this line. It’s a three hour Amtrak ride from Bakersfield to Merced including stops in Wasco and Hanford. HSR will not stop in Wasco. However, Wasco Amtrak passengers now have to walk through an underground walkway below the new, unused HSR structure in Wasco to get from the parking lot to the shiny, new replacement Amtrak platform. The Wasco Amtrak platform was working fine but was newly constructed as a part of the HSR project. Since the Amtrak line and the HSR are nearly parallel at this location, the overpass shown in the video had to be enormous. How many $ billions 💰 of taxpayer dollars will be spent to transport people between Bakersfield and Merced a little bit faster than Amtrak’s current three hour service? There’s no justification for spending so much money for so little benefit, that might occur ten years from now, or more.

Draymond Green says his first major lesson about taxes came after taking a $60,000 NBA salary advance and only receiving $28,000 “My first contract was three years, $2.6 million. I think I got drafted June 26. You don't get your first check until November 15. So from June 26 to November 15, you have to find a way to bridge that gap before you start getting paid” “Then once you sign your contract, which I didn't sign until after Summer League because as a second-round pick, you have to make the team. I didn't sign my contract until August. I didn't have any money” “In bridging that gap, the NBA allows you to take an advance of up to 15% of your salary as soon as you sign the contract. So I took out a $60,000 advance, and it hit my account, and it was $28,000. I'm excited. I've never seen $28,000, and it's right there” “So I called my agent and said, ‘Yo, this is amazing. It's $28,000 in my bank account. But where's the other $32,000. I'm missing some money’” “He's like, ‘Well, you know, taxes.’ I said, ‘What are you talking about. I'm supposed to get money back from taxes. He's like, ‘You're no longer in the position where you're going to get money back from taxes’” “Learning that right there at the very beginning, and understanding that anything you make, you can almost count it for half because half of it is going to the government. That immediately taught me you don't have as much money as you think you have, and you won't have as much money as you think you're about to make. That was really big for me”

This guy just explained Liberals vs Conservatives like we’re five… and it’s brutal because it’s dead accurate. Red team (Liberals): “We wanna spend like drunken sailors but we’re gonna keep all that oil, gas, and natural resources in the ground like it’s radioactive waste.” So how do they pay for it? Easy — they just take it straight from your pocket with endless taxes and fake “green” fees. Blue team (Conservatives): “Let’s actually use the resources God gave Canada, create real wealth, and let YOU keep more of your own damn money instead of treating taxpayers like an ATM.” One side wants to punish you for working and living. The other side wants Canada to actually prosper. Pretty simple when you stop listening to the propaganda and just watch what they do. Vote blue. Keep your money. Develop our resources. End the Liberal wealth transfer. Canada deserves better than poverty disguised as virtue. #LiberalFail #CarneyDisaster #cdnpoli #CanadaFirst #TaxationIsTheft #UseOurResources

I have spent the last 3 weeks working on a complicated tool/software for $AERO LPers to track their profits and losses across various liquidity pools on Aerodrome I have made immense progress so far but there is much more to accomplish before going public Not sugar coating it but there isn't a similar tool out there that is able to give accurate metrics and proper accounting Here's what it does right now > Compiles all your LP mints and withdrawal events > Computes the difference in USD value between entering an LP position and exiting it > This feeds to your impermanent loss or gain depending on the price movement of the underlying assets > Compiles all AERO rewards > Compiles all Fees earned (Since Aerodrome merges fees + LP position amounts when you withdraw, the tool had to separate principal from yield) > Compiles all gas fees paid > Gives you a USD denominated PnL > Gives you a net APR and a net return based on the period Here's what it doesn't do right now but will be added later > All AERO rewards have the USD value equivalent based on the price they were claimed at - future implementation would give them proper USD value based on your actions (selling vs holding) > No holding IL included (that's IL that is computed based on the difference between the moment an asset enters your wallet, either via purchase, transfer or LP event, and the moment it exists, either via a sell event, LP event or transfer. If it entered your wallet and you're still holding it then it gives your PnL between purchase timestamp and current price) > veAERO yield in case you've locked those claims and started voting with them > Live AERO rewards that are accruing in an active CL position > Full accounting for all Liquidity pools at once as it currently operates based on one LP / Gauge Once everything is tested and these additional things added then it will go public Prompting this terminal is going to be fully AERO aligned, meaning priced in AERO Would appreciate feedback

Mike Galsworthy, "How do you get a socialist Europe if you're not in it?" "The problem with the right wing surge and the far right surge are absolutely everywhere, and one of the best ways to deal with it is a robust pluralist system, with proportional representation, and that's what you're getting in Europe" Zack Polanski, "You don't hear politicians talking about Brexit much, have the catastrophic consequences of Brexit just gone away?" Mike Galsworthy, "Of course they haven't. The problem with Brexit is not that it was a one off event, we have put ourselves at a very disadvantageous position" "We're outside the team.
