2023 Hamas led attack on Israel happened as Hamas attacked Israel starting the Israel–Hamas war

- SpaceX's Starship rocket explosion last year created one of the largest holes ever detected in the ionosphere, stretching thousands of kilometers and lasting nearly an hour.
- The disturbance surprised researchers, highlighting gaps in understanding atmospheric processes and potential impacts on future autonomous vehicles requiring precise satellite navigation.
- The explosion's shockwaves turned the ionosphere into a neutral region, affecting satellite navigation signals over a vast area from Mexico's Yucatán peninsula to the southeastern United States.
- The ionospheric hole was smaller than the one caused by the 2022 Tongan volcano eruption but larger than the one from the 2013 Chelyabinsk meteor.
- Increasing rocket launch frequencies could pose growing challenges for satellite navigation, communications, and radio astronomy due to ionospheric disturbances.

The Holocaust: Sonderkommando work-unit members in Auschwitz concentration camp revolted upon learning that they were due to be killed; although a few managed to escape, most were massacred on the same day.

Was watching this guy predict bad things after lunar eclipse (that happened last week)

Exactly day after that, train derail, blast in Kerala, people burn NCP office etc (and few upsets in personal life too)

The coincidence was too uncanny

He also mentioned 3 months of extreme warfare - Middle East already burning, US and Afghanistan will also get involved.
US is still obvious, Afg is new. This is interesting to see unfold

If this happens & escalates then it is certainly a WWIII, stock market will crash by 3-5K points on day1 or 2, more layoffs, there will be chaos everywhere. 

This will be full fledged war between two countries, backed by two different axis. Please pray it doesn’t happen at all.

Welcome to Indian Startups's Private Community

I work at this company since 2+ years, day before yesterday company received an email from one of the two payment gateways that they use for catering Indian and International users for both payments as well as payouts. Now since the gateway that was catering the international users banned the company's account, all of the international transactions went to 0 quickly which was more than 90% of the total revenue, additionally they fined the company for $425,000

Now the problem for the company is:
1. The transactions completely stopped
2. A large sum of money in the account as balance is on hold by the payment gateway accounting to approximately, 1/5th of fine.
3. The fine which the payment gateway is charging, doesn't have any underlying reason as why the fine amount is so big.
4 There's absolutely no reply from the payment gateway on the email hence no way to contact directly.

Now, the thing is company knew this day was possible but they had took preventive measures as well and weren't expecting this to happen anytime soon and atleast with a prior notice unlike which landed like a bomb with a brief (text only) email.

So there are features called radar and chargeback protection in the payment gateway which take some percentage of your transaction to ensure if there are some fraudulent/illegal transactions they will flag those transactions and prevent the customers (our company in this case) from getting disputes from the card owner/payee, having which of no use to the company. As per the terms, a threshold percentage of your transactions need to be disputed in order to be flagged as suspicious for the payment gateway which was way less in the company's case.

Although company too could have prevented this from just banning users whose payments were getting disputed by the card holders claiming they didn't authorise the purchase or either the user didn't deliver for what the payment was done by the payee. In either of the case banning that user was the ideal action.

- **China launched** an intercontinental ballistic missile (ICBM) into the Pacific Ocean on September 25, the first such test since 1980.
- **Beijing downplayed** the event, calling it a routine part of annual training, but it was anything but routine.
- **Advance warnings** were given to select nations, including the USA, which deployed an RC-135S Cobra Ball aircraft to collect data.
- **The missile flew** approximately 12,000km, demonstrating China's capability to reach the USA.
- **The test raised** concerns among nations like New Zealand, Australia, and Japan, who demanded explanations from China.

- Scientists have developed an AI system to predict catastrophic tipping points in complex systems like ecological collapse and pandemics.
- The AI combines neural networks to analyze large networks of interacting nodes and their changes over time.
- Researchers successfully tested the AI on real-world data, predicting the transformation of tropical forests into savannah.
- The AI's predictions could help prepare for or prevent critical transitions, potentially mitigating damage.
- Challenges remain, especially in human-involved systems where behavior can alter outcomes, but researchers are optimistic.
