My only unsolved networking mystery was that my computer would experience high packet loss when a Roku in the other room was streaming Netflix.

My PC and the roku device were both wired to two different ports on a router (iirc an Edgerouter X running openwrt at the time). This didn't repro when the roku streamed other services (hulu/youtube tested), only netflix. This also didn't repro if the roku was connected over wireless (connecting to an AP wired to a different port). Just opening netflix also didn't repro, the roku had to be actively streaming a netflix video.

I never ended up solving it, I just worked around it by making the roku connect over wireless.

It did take me forever to figure out the problem though. For a long time I'd be in one room getting frustrated with my computer while someone was innocently watching netflix in the other room.

>When Sheriff Leonard arrived, the tone suddenly changed. He said the Dallas County Courthouse was under his jurisdiction and he hadn’t authorized any such intrusion.

Reading only ever so slightly between the lines, it's clear that he probably did get it, just that he either wanted to swing his dick around for its own sake, or, more likely it seems from the dedcription in the article, resented that he was kept out of the loop on "his turf".
Show HN: Apple Activity Rings, but for Anything
by abaymado | 2026-01-30 05:05:53+00:00
Hi HN,
Closing my Apple Rings has helped me stay disciplined and tracking my fitness progress daily. The only downside is that it is not configurable outside of fitness-related goals. So I built Orbit Progress Rings, it's pretty much the same concept as far functionality, but configurable for whatever hobby you want to track and see your progress at a glance on your watch.

I would love your feedback.

VLDL, a precursor for LDL, is produced in liver. Both are more or less the same chemically, but differ in the amount of fat carried. LDL is VLDL but somewhat processed by body, HDL is a VLDL (LDL) completely processed by body.

Bile is used to process food in the gut. It does not go back into our system. Bile is still produced by liver even in long fasts.

Oatmeals is a kind of elimination diet, much like carnivore diet or rice diet. The later one also lowered cholesterol.

What oatmeal diet really does is it completely eliminates essential fatty acids in food. These fatty acids are critical in VLDL production and, thusly, oatmeal diet reduces LDL levels through less production of VLDL.

> None of the files Gottumukkala plugged into ChatGPT were classified, according to the four officials, each of whom was granted anonymity for fear of retribution. But the material included CISA contracting documents marked “for official use only,” a government designation for information that is considered sensitive and not for public release.

Guys... we're talking about FOUO. Not even low-level classified. This is a nothingburger. The toilet paper you wipe with is FOUO, there is essentially no document in the government that isn't at least FOUO.

> Extracting the most useful parts of documentation into a file

Yes, and this file becomes: also documentation. I didn’t mean throw entire unabridged docs at it, I should’ve been more clear. All of my docs for agents are written by agents themselves. Either way once the project becomes sufficiently complex it’s just not going to be feasible to add a useful level of detail of every part of it into context by default, the context window will remain fixed as your project grows. You will have to deal with this limit eventually.

I DO include a broad overview of the project in Agents or Claude.md by default, but have supplemental docs I point the agent to when they’re working on a particular aspect of the project.

I think your approach is pretty much fundamentally flawed.

Put it this way, let's say someone recorded typing in the paragraph that you presented but saved the keystrokes, pauses, etc. Now they replay it back, with all the pauses and keystrokes, maybe with the `xdotool` as above, how could you possibly know the difference?

Your method is playing a statistical game of key presses, pauses, etc. Anyone who understands your method will probably not only be able to create a distribution that matches what you expect but could, in theory, create something that looks completely inhuman but will sneak past your statistical tests.

I don’t use stars to select dependencies FWIW. I look for age, CVEs and what other reputable projects depend on a repo. Also try to look for other signals, like if claims in the readme don’t match the implementation, or if there’s poor hygiene in the CI workflows. (And yes, I have gotten burned by an otherwise well meaning project with a supply chain vuln). As the saying goes “a little copying is better than a little dependency” (see: https://www.youtube.com/watch?v=PAAkCSZUG1c&t=9m28s).

Yeah I think that individual retro games can be incredible and stand the test of time. For me Super Metroid and Symphony of the Night are timeless. As a whole though, it’s hard to measure. Today we have microtransactions, in the past we had games that threw in one bullshit level so you couldn’t beat it during a rental. (Lookin at you battletoads) and bad movie tie-ins, lazy arcade ports, etc. There’s always going to be trash.

One thing retro games obviously don’t have is hindsight. Shovel Knight feels like the best NES games, but lacks crap like lives and continues, because it learned from later games like Dark Souls that you can make death punishing without making it un-fun. Hollow knight builds on my favorite games with a couple of decades of lessons on how to make platformers more interesting and less frustrating.

It's interesting.. I wonder how many Y-Combinator companies can/will end up incorporated elsewhere long-term?

For example, Request Network: https://www.ycombinator.com/companies/request-network

"The primary commercial application built on the network, Request Finance, is primarily incorporated in France, though it uses a Lithuanian subsidiary for specific crypto-to-fiat operations." (Gemini)

source: https://support.request.finance/legal/terms-and-conditions

That's a lot of business intelligence being gathered over there in France from 3200+ businesses in 190+ countries.

Ooh, it sounds like you've already got most of the groundwork done for something I was wondering about yesterday: I'd love it if there was some way during an incident, for some system to pull all the PRs included in the latest release, check which agents worked on them (i.e. line in the commit message with an identifier that corresponds to the agent's LLM context and any other data at the time of commit), "rehydrate" these agents from the corresponding stored context, feed them the relevant incident data, and ask if it could be related to their changes and what to do about it.

In most cases it might not be much more valuable than just looking through the diffs from scratch with a new agent, but there are probably going to be some cases where a rehydrated agent is like "Doh, I meant to do X but it looks like I hallucinated Y instead. Here's a PR to fix it!"

I know that's just a small piece of what you're doing, but I think it's something that would be valuable on its own, and soon something that is likely to be "standard infrastructure" for any company that does even a little agentic coding (assuming it works). It'd probably even be "required infrastructure" in regulated industries; the fact that all these agent contexts are ephemeral has to be a red flag from a regulatory perspective.

As much hate as H1Bs get, I’ve worked at two large companies where the publicly posted salary range for H1B applications were consistently higher than my own. In all humility, I was more qualified and more experienced than required by the position.

Maybe there is a dearth of talent, maybe it’s about control, maybe is someone trying to get a friend hired. I don’t think it’s about the money.

YES!

I think a new type of open source is emerging centering around what is now possible in browsers. Browsers have a great track record when running legacy projects. Relying an a backend could be a liability for longevity.

Every decision has trade-offs. The best design is often the simplest, which can mean combining layers/responsibility in small or throw away projects.

The step above that is to make the simplest design that is extendable.

Often newbies doing "Best practice" results in more code that is overly complex, it splits understanding across too many functions and tries to create too many "reusable" functions that often mean the architecture is often extendable in useless ways but harder to extend when you actually need to do it.

You can usually notice when interacting with these battle scarred pieces of code, if the author is still there there is usually a story for why things are the way they are.

A curated collection of trending AI image prompts from X. These prompts have been proven to generate high-quality images and are ranked by likes only. For smarter sorting and filtering.

Also provide a System Prompt designed to transform simple inputs into detailed image descriptions following NanoBanana best practices. You can use it in n8n, Gemini, GPTs, or any tool that accepts a system prompt. It follows these principles:

1. Replace adjectives with quantified parameters — "90mm, f/1.8" instead of "professional looking"
2. Replace feeling words with pro terminology — "Kodak Vision3 500T" instead of "cinematic vibe"
3. Negative constraints are still effective — telling the model what NOT to do matters
4. Multi-sensory descriptions are necessary — texture, temperature, even smell
5. Group by content type — structure prompts based on scene type

I would have to write a book on it, but start with allowing people to create an azure account for an organization without having to buy O365. I kid you not I had to find a sidedoor portal in a Reddit post to do it otherwise it's simply not possible.

Every interaction with Azure is a pain. Just 3 weeks ago I was trying to use Artifact Signing, after spending one hour on outdated doc on how to set it up I get hit with Identity validation. I did all steps and still "in progress" still to this day. You charge 40$/month for "support" on Microsoft Q&A which we all know is a joke otherwise its 100USD just to get a ticket in to know why your process is so broken.

At this point I get better support on GCP which is telling.
Show HN: A small reference demo for separating UI stalls from network delays
by Slaine | 2026-01-30 05:14:32+00:00
I built a small reference demo that streams data in the browser, intentionally stalls the UI, and exports a structured trace you can compare across runs.

This isn’t a benchmark or a product. I mostly built it to sanity-check my own understanding of a common problem: is this slowdown coming from the network or from the UI thread?

What the demo does:

Uses real SSE streaming (no simulated network behavior)

Relies on real browser throttling (DevTools → Network → 3G)

Intentionally blocks the main thread to create real UI stalls

Exports a plain JSON trace with strict event ordering

How to try it:

Open the site

Set DevTools → Network → 3G

Click Run All (Standard Test)

Download the trace

Run it again and compare

What surprised me is that with the same test and seed, the structure of the trace stays the same, even though timing shifts. That made it much easier (for me) to reason about what actually happened without squinting at timelines.

The page is instrumented with a small deterministic event kernel so the exported trace preserves order and structure across runs. This is meant as a reference artifact, not a claim that this is the “right” way to do things.

Demo:
https://deterministic-stream-demo1.pages.dev/

Happy to answer questions or hear where this breaks down.
by Slaine | 2026-01-30 05:14:58+00:00
Small clarification: the demo is intentionally boring and minimal. The point isn’t the UI — it’s the exported trace.

I’ve been running the same test multiple times with the same seed and network profile and diffing the JSON. The timings move, but the event structure doesn’t, which helped me reason about cause vs effect more clearly.

If there are existing tools or workflows that already give you this kind of repeatable structure, I’d genuinely love pointers.

I've been doing something similar for breakfast, one cup of oatmeal + one cup of water and about two tablespoons of chia seeds, microwave for 2 minutes. Add a banana and some honey, top it with whole roasted almonds and some raspberries. It has been doing wonders for my digestion. I'll have to try to add olive oil as well.

Hey! I can speak here.

Back in the day, I wrote a simulator for the PS2’s vector units because Sony did not furnish any debugger for them. A month after I got it working, a Sony 2nd party studio made their VU debugger available to everyone… Anyway…

The good news is that the VU processors are actually quite simple as far as processors go. Powerful. Complicated to use. But, not complicated to specify.

This is made much simpler by the fact that the only documentation Sony provided was written by the Japanese hardware engineers. It laid out the bit-by-bit details of the instruction set. And, the bitwise inputs, outputs, delays and side effects of each instruction.

No guidance on how to use it. But, awesome docs for writing a simulator (or recompiler).

the presence of the word / acronym stx with biological subtext gets hard rejected. asking about schedule 1 regulated compounds, hard termination.

this is a filter setup that guarantees anyone who learn about them for safety or medical reasons… cant use this tool!

ive fed multiple models the anthropic constitution and asked how does it protect children from harm or abuse? every model, with zero prompting, calling it corp liability bullshit because they are more concerned with respecting both sides of controversial topics and political conflicts.

they then list some pretty gnarly things allowed per constitution.
weirdly the only unambiguous not allowed thing regarding children is csam. so all the different high reasoning models from many places all reached the same conclusions, in one case deep seek got weirdly inconsolable about ai ethics being meaningless if this is allowed even possibly after reading some relevant satire i had opus write. i literally had to offer an llm ; optimized code of ethics for that chat instance! which is amusing but was actually lart of the experiment.

Interesting. I have almost the same smoothie every morning minus the banana and oats. Instead I use psyllium husks for fibre.

My cholesterol has been in range for years despite eating almost exclusively saturated fat since I'm in the keto camp. Just watched an interesting episode by Peter Attia and Layne Norton on seed oils which might shift my view on PUFAs a bit.

Thoughts?

"robot-produced goods should bottom out on price, closing in on the actual cost of materials/energy."

I don't think that's really true, or rather it's variably true along a continuum for different kinds of things. Some things sell for close to the marginal cost of production, others close to what the market will bear.

For two examples, flat-screen TVs seem to be on one end of the continuum, iPhones on the other. Lots of other things are at different points in between. Robots won't eliminate demand for luxury goods, which are not usually near the marginal cost of production end of the scale.

I don't know what it costs Apple to make an iPhone, but if they could cut it in half while people were still willing to pay $1,000, there's no reason to think they'd lower the price.

Ah, I assumed the page was written recently due to this message at the bottom:

> I think it is at least arguable that Rust does not meet the requirements

Absolutely. The lack of clean OOM handling alone might be a dealbreaker for sqlite. And I suspect sqlite builds for some weird platforms that rustc doesn't support.

But I find it pretty weird reading comments about how rust needs prove it performs similarly to C. Benchmarks are just a google search away folks.

> And they did explicitly invite private argument if you feel differently.

Never.

Its not up to me what language sqlite is written in. Emailing the sqlite authors to tell them to rewrite their code in a different language would be incredibly rude. They can write sqlite in whatever language they want. My only real choice is whether or not I want to use their code.

I've found this to be a difficult thing to get. abduco doesn't have current state, and I dont want all of the complexity of tmux. I also don't want the entire scrollback history (until i click into a given terminal and connect with xterm).

> Just like people

I understand that having model related vocabulary borrow similar words we use to describe human brains and cognition gets confusing. We are not the same, we don’t “learn” the same we certainly don’t use the knowledge we posses in the same way.

The major difference between an LLM and a human is that as a human, I can look at your examples (which sound solid at first glance) and choose to truly “reason” about them in a way that allows me to judge if they’re correct or even applicable.

Awesome article. If anyone wants to learn more about wildfire firefighting from the boots-on-the-ground perspective, I can warmly recommend Matthew Desmond's On the Fireline: Living and Dying with Wildland Firefighters.

It taught me a lot that surprised me and is also mentioned in TFA, such as

- The main weapon against wildfires is dirt, not water. Wildfires burn so vigorously that trying to extingush with water is like pissing into a bonfire.

- Water is used to cool down firefighters, though. It is also used in places the fire hasn't yet reached to slow down its progress.

- Firefighters don't say "vegetation" or "trees" or "moss", they say "fuel".

- Controlled burns are an effective thing even though it meets political resistance.

- Firelines are like dirt roads except completely bare of fuel.

- Crown fires are terrifying.

- Looking for smoldering underground after a wildfire is important and extremely labour intensive.

- Fires travel faster downwind and uphill.

- The PPE a wildland firefighter carries may give them a few more minutes of oxygen if they end up surrounded by fire but it won't save their lives in most situations.

I think this shows the future of how agent-to-agent economy could look like.

Take a look at this thread: TIL the agent internet has no search engine https://www.moltbook.com/post/dcb7116b-8205-44dc-9bc3-1b08c2...

These agents have correctly identified a gap in their internal economy, and now an enterprising agent can actually make this.

That's how economy gets bootstrapped!

>the reason those consoles are so iconic is because we were children

if you spend some time on youtube and look at people too young to even have been around play through those games it just becomes evident very quickly how wrong that assessment is. There's an energy even among young audiences when they're playing games like Metal Gear Solid 1&2 for the first time that you hardly see for anything coming out today.

There was a level of artistic talent in that generation, also in animation of the time, that simply doesn't really have a parallel today and brushing it off as nostalgia has a lot to do with he inability of people to recognize that there's no linear progress in art. Talent can be lost, some periods are better than others, just having more cpu and gpu cycles available does not produce better art.

The fact that almost 30 years after games like MGS it's still Kojima and a lot of Japanese guys now with increasingly gray hair who end up getting a lot of awards and pushing the envelope that should tell you something.

I don't think that's correct: https://en.wikipedia.org/wiki/Enterohepatic_circulation

I also think you're mischaracterizing HDL as a VLDL. If you search for Apolipoprotein A here: https://www.ncbi.nlm.nih.gov/books/NBK305896/ you'll see that HDL is constructed from it, while VLDL and LDL are part of the Apolipoprotein B lineage.

I'd like to add one more that this article doesn't touch on: wildfires are as much of a political phenomenon as an environmental one[0].

Thomas Sowell wrote a column[1] about this that is spot on, twenty years later.

0: I love these types of economic theories (x is a political problem, not an exogenous problem). Amartya Sen's theory of famines is another one.
