Report Phone Spam – Shut down robocallers and text spammers

Do you receive unsolicited phone calls or SMS/text spam? I made a free public service site explaining how to find the telecom carrier that is responsible for the spammer's (real) phone number and report the abuse to them – so the carrier can terminate their service.<p>It works, and it feels like magic.<p>Background: Earlier this year, I wrote an HN comment[1] explaining how to find the telecom carrier responsible for a robocall or SMS spam campaign. Those steps aren't documented anywhere else, even though they're actually pretty easy.<p>This info deserved to be much more visible, so now it is: <a href="https://reportphonespam.org/" rel="nofollow noreferrer">https://reportphonespam.org/</a><p>As my site says, most reputable telecom carriers don't want unsolicited messages on their network or phone numbers. In order to disconnect their abusive customers, they need to hear about the abuse. That's where you come in. In a few minutes, you can report abuse to the responsible carrier, who will investigate and often shut off the spammer's phone number(s).<p>[1]: <a href="https://news.ycombinator.com/item?id=34570065#34570835">https://news.ycombinator.com/item?id=34570065#34570835</a>

Show HN: 80% faster, 50% less memory, 0% loss of accuracy Llama finetuning

Hi HN! I'm just sharing a project I've been working on during the LLM Efficiency Challenge - you can now finetune Llama with QLoRA 5x faster than Huggingface's original implementation on your own local GPU. Some highlights:<p>1. Manual autograd engine - hand derived backprop steps.<p>2. QLoRA / LoRA 80% faster, 50% less memory.<p>3. All kernels written in OpenAI's Triton language.<p>4. 0% loss in accuracy - no approximation methods - all exact.<p>5. No change of hardware necessary. Supports NVIDIA GPUs since 2018+. CUDA 7.5+.<p>6. Flash Attention support via Xformers.<p>7. Supports 4bit and 16bit LoRA finetuning.<p>8. Train Slim Orca fully locally in 260 hours from 1301 hours (5x faster).<p>9. Open source version trains 5x faster or you can check out Unsloth Pro and Max codepaths for 30x faster training!<p><a href="https://www.reddit.com/r/LocalLLaMA/comments/188197j/80_faster_50_less_memory_0_accuracy_loss_llama/" rel="nofollow noreferrer">https://www.reddit.com/r/LocalLLaMA/comments/188197j/80_fast...</a> has more info about Unsloth!<p>Hopefully you can try it out! Wrote a blog post at <a href="https://unsloth.ai/introducing" rel="nofollow noreferrer">https://unsloth.ai/introducing</a> if you want to learn more about our manual hand derived backprop or Triton kernels and stuff! Thanks once again!
