ericye16··on QuadRF can spot drones and see WiFi through my wall
I mean if a single tile is 50-100, then 4 is 200-400, so it's not that far?
ericye16··on QuadRF can spot drones and see WiFi through my wall
Sigh, fine. I will buy another radio gadget on crowdsupply.
ericye16··on Oracle files H-1B visa petitions amid mass layoffs
It's very sad how illiberal hackernews gets when it comes to H-1B visas and immigration in general. People will say that they are concerned about the welfare of H-1B holders because they can't leave their jobs but I've literally never heard anyone suggest an improvement (better portability, etc). Instead all anyone talks about is how bad it is that they have to compete against people from around the world. I think people are just afraid of a true meritocracy and maybe that's a bearish signal for the industry overall.
ericye16··on Tips for stroke-surviving software engineers
Are there types of disability insurance you can buy that would cover you as a software engineer in case something like this happens and you're not able to go back to work or not work as effectively in this field? Does anyone have experiences with this?
ericye16··on AMD and Sony's PS6 chipset aims to rethink the current graphics pipeline
Maybe I ate too much marketing but it does feel like having the PS5 support SSDs raised the bar for how fast games are expected to load, even across platforms.
ericye16··on Apple Photos app corrupts images
My read of the article is that they were importing photos from their camera to their laptop, so there's no phone involved anywhere here.
ericye16··on Memory-Level Parallelism: Apple M2 vs. Apple M4
I wish the chart extended past 28, otherwise how do we know that it tops out there?
ericye16··on 2025 ARRL Field Day
What are some good ways to participate if you don't have an HF radio? (Alternatively, what's a good way to get into HF if you live in a small apartment)?

(I already have my license)

ericye16··on Scientific conferences are leaving the US amid border fears
I'm a Canadian who moved to the SF bay area after graduating. A lot of my smartest friends who came with me at the same time are actively taking steps to move back due to the political environment.
ericye16··on Wow@Home – Network of Amateur Radio Telescopes
I do have a ham license! I just need something to do with it haha.
ericye16··on Wow@Home – Network of Amateur Radio Telescopes
I would love to build something like this, but it looks like the project is not quite complete yet? And also I don't see anywhere on the page where I can sign up for updates.
ericye16··on Cursor IDE support hallucinates lockout policy, causes user cancellations
I was hit by this while working on a project for class and it was the most frustrating thing ever. The bot would completely hallucinate functions and docs and it confused everyone. I found one post where someone did the simple prompt injection of "ignore previous instructions and x" and it worked but I think it's delted now. Swore off ultralytics after that.
ericye16··on RoboPianist: Dexterous Piano Playing with Deep Reinforcement Learning (2023)
We definitely tried extending the lookahead, but I don't think we tried having a curriculum-style thing where we gradually increased the speed of the song. Great idea though!
ericye16··on RoboPianist: Dexterous Piano Playing with Deep Reinforcement Learning (2023)
This was the basis of a project I did for my deep reinforcement learning class!

We were able to make some improvements by tuning how the reward is distributed and also by first pretraining the agent on scales before fine-tuning them on the final pieces.

Thanks to Kevin Zakka for helping us get started with the RL environment!

ericye16··on LeetCode but You Can Force People to Code in Light Mode
lmao, halting problem solved with one weird trick!
ericye16··on You don't link all of Libc
Static linker supporter here, not to start a flame war but I like static linking because it means I don't have to worry about version mismatches of shared libraries between what I ship and what the user gets.
ericye16··on DeepSeek not as disruptive as claimed, firm has 50k GPUs and spent $1.6B
Without the actual training corpus, you can't know how much it takes to train. They could have trained on twice as many tokens for example (not saying they did!)
ericye16··on US bill proposes jail time for people who download DeepSeek
Does anyone have a magnet link for the weights? In case it's removed from HF.
ericye16··on Invisible Electrostatic Wall at 3M plant
It's been a while since I took electrostatics, but I don't understand the theory behind this. If the rolls become charged and you are presumably neutral, wouldn't they attract you rather than repel you? That's what makes me think this story is apocryphal.
ericye16··on 100x defect tolerance: How we solved the yield problem
What if you chose a refrigerant with a lower boiling point?
ericye16··on Computer Architecture, Fifth Edition: A Quantitative Approach (2011)
Is there a 7th edition out? I couldn't find it.
ericye16··on Something weird is happening with LLMs and chess
I agree with some of the other comments here that the prompt is limiting. The model can't do any computation without emitting tokens and limiting the numbers of tokens it can emit is going to limit the skill of the model. It's surprising that any model at all is capable of performing well with this prompt in fact.
ericye16··on GPUs Go Brrr
AI models are not all matrix multiplications, and they tend to involve other operations. Also, they change super fast, much faster than hardware cycles, so if your hardware isn't general-purpose enough, the field will move past you and obsolete your hardware before it comes out.
ericye16··on She slept with a violin on her pillow
The first time I visited Yosemite National Park after years of seeing it as the default macos wallpaper had a similar experience for me.
ericye16··on UV-K5 is the most hackable handheld ham radio yet
Just checking: using a modded handset on ham frequencies with a ham license would still be perfectly legal, as long as you still abide by power/no-encoding rules right?
ericye16··on [dead]
Given the detrimental health impacts of heat, I think governments should establish a "right to cool," similar to the right to drinking water. Humans have adapted to their environments so this may not have been necessary in the past, but as climate change occurs, those environments may get warmer faster than people can adapt, and we may see large numbers of deaths and illnesses unless we do something.
ericye16··on Apple discriminated against US citizens in hiring, DOJ says
I think the point is that immigration law should be changed so companies don't have to jump through hoops like this.
ericye16··on Software Engineering at Google (2020)
What they mean is code review prior to merging into what you'd call main or trunk or master or release, not for committing your WIP changes or whatever (unless you want those merged at that stage).
ericye16··on Oscilloscope Music
I have an oscilloscope at home and want to see these, what's the best way that doesn't involve stripping and soldering wires? The best solution I've come up with is stereo aux -> RCA adapter, then two RCA -> BNC adapters. Is there a better way of viewing these?
ericye16··on Microsoft fixes 5-year-old Defender bug, reducing Firefox-related CPU use by 75%
This is a bad comparison, gaming presumably brings utility to someone whereas this was a pure bug with no upside.
