Laptop 'D' key doesn't work alone, but types "sd" when pressed with 'S'. Any fix?

My laptop's 'D' key has stopped working completely when pressed by itself. However, if I press

'S' and 'D' together, it successfully types out "sd".

Is this a hardware/keyboard matrix issue, or a weird

software glitch?

Fear of negative balance/debt on leverage: Can I lose more than 100% of my principal?

I'm looking into trading Bitcoin with some leverage, and I want to make sure I fully understand the worst-case scenario regarding liquidations.

​To be absolutely clear: I am 100% fine with my position going to zero. I am willing to take the risk of losing my entire initial margin/principal.

​However, what absolutely terrifies me is negative equity (deficit risk). If the market gaps down or crashes incredibly fast, and the exchange fails to liquidate my position in time, can I actually end up owing money to the exchange?

Is cross-border e-commerce still viable in 2026? What vertical niches are left for regular folks to survive?

Hey guys, looking to pivot into cross-border e-commerce and wanted to do a quick reality check. At this point in 2026, what vertical niches are actually left for a regular guy or a small team to survive?

​Low-ticket generics are completely monopolized by Temu/Shein's fully-managed models and factory-direct giants. Competing on price is suicide. I’ve mapped out 3 potential directions—tell me if I’m delusional:

​High-Ticket + Ultra-Vertical Niches: Hardcore 3C gadget mods, specialized geek/outdoor tools, or high-performance material consumables. Relying on healthy margins to absorb high CAC.

​Content-Driven E-commerce (TikTok to DTC): Building a tailored brand/IP for specific subcultures (like Anime/ACG) and driving traffic to a Shopify store via short-form video. Content skills over price wars.

​Heavy Service + Overseas Warehousing: Oversized items or hardware that requires installation support. Going local from day one to filter out the no-inventory dropshippers.

​My bottleneck:

I have some technical leverage (web scraping, automated data analytics) and about $10k–$20k in starting capital. Should I dive into hyper-competitive Western markets (US/UK) with a micro-niche, or chase "new money" in emerging markets like SEA or Latin America?

​What sectors are you guys focusing on this year? Feel free to brutally wake me up or drop your thoughts below!

Liquid metal or phase-change thermal pads on a gaming laptop? Worth the risk?

My gaming laptop runs incredibly hot during heavy sessions. I'm seriously considering repasting with liquid metal or a phase-change thermal pad.

​Has anyone here actually tried this? Did it drop temps enough to justify the risk of bricking it?
