User: why did the singer from Journey stop singing? 
Assistant: The lead singer of Journey, Steve Perry, took a long hiatus from performing due to various personal and health reasons. After the release of the band's album "Trial by Fire" in 1996, Perry faced several challenges, including a hip issue that required surgery, which ultimately affected his ability to perform. He also took time off to deal with personal matters and to focus on his well-being.

Perry's absence from the band lasted for many years, but he eventually returned to music. In 2018, he released his first solo album in nearly two decades, titled "Traces." Although he stepped away from Journey for a long time, his passion for music never completely faded, and he has since resumed his career sporadically.
User: what's a tenkeyless keyboard? What's so special about them?
Assistant: A tenkeyless keyboard, often abbreviated as TKL, is a type of keyboard that omits the number pad (the "ten keys") typically found on the right side of a standard full-sized keyboard. This design typically includes the main alphanumeric keys, function keys, and navigation keys, but excludes the additional numeric keypad.

The special features of tenkeyless keyboards include:

1. **Space-Saving Design**: Without the number pad, TKL keyboards take up less desk space, making them an excellent choice for users with limited desk real estate or those who prefer a more minimalist setup.

2. **Improved Ergonomics**: The compact design allows for a more natural placement of the mouse, which can reduce shoulder strain and improve overall ergonomics, especially in environments where users switch between typing and using a mouse frequently.

3. **Portability**: TKL keyboards are lighter and easier to transport, making them a popular choice for gamers and professionals who travel frequently and want to carry a keyboard that takes up less room in their bags.

4. **Customization Options**: Many gaming and mechanical TKL keyboards offer customizable features such as programmable keys, RGB lighting, and various switch options, appealing to gaming enthusiasts and typists alike.

5. **Performance**: Many TKL keyboards are designed with gaming in mind, offering faster response times, durability, and features that cater to gamers or serious typists seeking a high-performance keyboard.

Overall, tenkeyless keyboards appeal to a wide range of users for their blend of functionality, ergonomics, and portability.
User: when it comes to trading bots, what's a live broker and a paper broker? 
Assistant: In the context of trading bots and automated trading systems, the terms "live broker" and "paper broker" refer to different environments in which trading occurs:

1. **Live Broker**:
   - A live broker refers to a trading platform or brokerage that facilitates real-time trading with actual funds. When using a live broker, traders execute real buy and sell orders in the financial markets, affecting their actual trading accounts and portfolios.
   - Trades made through a live broker involve real money, which means that profits and losses affect the trader’s actual capital. It requires a funded account and often comes with various trading fees, commissions, and other associated costs.
   - Using a live broker can provide traders with hands-on experience and the opportunity to test strategies in real-market conditions.

2. **Paper Broker** (or Paper Trading):
   - A paper broker, on the other hand, is a simulated trading environment that allows traders to practice their strategies without risking real money. It provides a risk-free way to test and refine trading algorithms or strategies by using a fake trading account that mimics the behavior of a live account.
   - In a paper trading setup, traders can monitor trades, strategies, and market movements as they would in a live scenario, but without financial consequences. This helps traders develop skills, understand market mechanics, and assess the performance of their trading bots before committing real capital.
   - Paper trading is often used by beginners to learn the basics, while advanced traders may use it to test new ideas or strategies without financial risk.

In summary, the key difference between the two is that a live broker involves actual trading with real money and real consequences, while a paper broker involves simulated trading without any financial risk.
