This is not a valid argument. TPS is essentially QoS and can be adjusted; more GPUs allocated will result in higher speed.

Actually, Opus might achieve a lower cost with the help of TPUs.

other filesystems are just as susceptible to data corruption from memory errors. this is not a weakness unique to ZFS.

While this guide covers roughly 80% of the material, it remains a high-level overview that lacks depth. I can't confirm if it was LLM-generated, but the content is undeniably superficial. Real-world production environments are far more complex; for instance, despite other users mentioning hugepages and TLB, there is no discussion of critical issues like TLB shootdown.

The reason is that you are not a Computer Science PhD. But soft skills (such as storytelling, sense of ownership, etc.) can still be passed down

You can buy a used AX1800 with OpenWrt in China for around five or six euros.... XD

A safer approach is to treat Tor only as a special obfuscation method.

Besides technical details, in a normal usage scenario, the context length is also much greater than the generation length.

One strong point of Grammarly comes from its friendly display of diffs (which is somewhat similar to what Cursor does). This project simply uses some predefined prompts to generate text and then replaces it. There are countless plugins that can achieve this, such as the OpenAI translator.

If this tool really wants to compete with Grammarly.
