> To prevent impairment of sound quality, we recommend cables with cross-sections of at least 2.5 mm² for lengths up to 3 m and at least 4 mm² for lengths above 3 m.

This is just a unit issue. See:

https://www.engineeringtoolbox.com/wire-gauges-d_419.html

Those numbers are also ridiculous. They’re recommending 13AWG or higher for a 3m run. That’s about 20 feet round trip, which is about 0.04 ohms. The speaker should be 8 ohms nominal, but let’s call it 1 ohm at some very audible frequency to be conservative. So you might lose 2% of your power or maybe 0.1dB. Keep in mind that you cannot hear frequency-independent attention at all (the volume knob fixed it), so you’ll only hear the frequency-dependent part, which will be smaller, and your speaker plus room already has frequency dependence far in excess of 0.1dB.

I will admit that there is a good reason to use at least 18AWG cable or so: speaker cable terminations are utter crap, and the crappiness seems to get worse as the fanciness goes up. A thicker wire is more likely to survive being terminated, within limits.

Buy some 16AWG two-conductor CL2 or CL2R or CL2P cable at your home improvement store and be done with it.

> Unless you're running speaker cables parallel to some power cables, shielding is not a requirement from my experience.

I have never heard mains hum coupled from a passive speaker cable. That’s not really a thing — there just isn’t enough power to make it audible under normal conditions.

"Exercise" in these studies could be something like leisure walking for a couple of hours. That can only affect your weight by keeping you away from your snacks for a couple of hours, its energy expenditure is not moving your weight in any direction. If you look up, the energy cost of light activity is exaggerated. You can get numbers as high as 1 kcal / (kg*km) so somebody who is 100kg (220lbs) supposedly burns 500 kcals in a 1 hour of walking at 5 km/h (20 minutes mile). I know people who believe these numbers, think themselves at a caloric deficit and, when still gaining weight, doubt the Thermodynamics instead of the exercise "science".

The closest thing to an IBM PC and daq is… an Arduino. Simple cpu, simple interface library, go from zero to making stuff move in no time.

A modern PC as a platform is in no way helpful to learning how sensors and actuators work. You’d be spending hundreds more for unnecessary frustration.

The Art of Electronics is not a good choice for a beginner. It’s aimed at good university educated EE’s.

I fear that these news publishers would come after RSS next as I see hundreds of AI companies misusing the terms of the news publishers's RSS feed for profit on mass scraping.

They do not care and we will be all worse off for it if these AI companies keep continuing to bombard news publishers RSS feeds.

It is a shame that the open web as we know it is closing down because of these AI companies.

> even the basic airpods provide plenty of resolution and detail

My information might be outdated, but aren’t those the kind that sort of sit loosely at the outside of your ear canal (like the original iPod headphones)? If so, those are the one kind of headphones that I find basically worthless. I’m not an audiophile by any stretch of the imagination, but in the iPod era I could never understand how people tolerated those when you can get 5x better sound for a few bucks.

AirPod pro sounds fine, though.

Yes, two in fact. One is the same prefix (with subtle differences of course, it's x86) that was introduced for AVX512's 32 registers. The other is new and it's a two byte extension (0xd6 0x??) of the REX prefix (0x40-0x4f).

The longer prefix has extra functionality such as adding a third operand (i.e. add r8, r15, r16), blocking flags update, and accessing a few new instructions (push2, pop2, ccmp, ctest, cfcmov).

> My point is there is no non-LLM service.

Considering Stoat just (supposedly) removed all LLM code from their code base, there is at least one. I’d expect, based on Meredith Whittaker’s stance regarding LLMs, that Signal also doesn’t have LLM code, though I haven’t verified.

> The commenters simply focus on the thing they saw, and didn't even bother comparing against their existing alternative.

I mean, how do you know? There is one mention of Discord in that thread. Making sweeping statements about “the commenters” doesn’t seem right.

You are not wrong. I blew up a great career that burned me out to go on a journey that was absolutely crushing to emerge with a machine that allows me to have the deepest technical conversations of my entire career. Professionally isolated for sure. But, im married and have friends so its not that bad and dont worry.

I just came to many observations about myself and AI has helped process so many emotions that I would never share with another human.

This is a schoolboy error. Requires != includes.

The meme about AMA artificially limiting the supply of new residency slots turned out to be much more complex the more I read about it (and IMO mostly incorrect, at least as described by the just-so stories on the internet where I first learned about it).

The actual limiting factor is federally funded residency positions which are funded by CMMS, and were artificially capped by the Balanced Budget Act of 1997 during a widespread climate of financial austerity after Gingrich had led Republicans to retake the House in 1994 for the first time in decades.

At the time, AMA apparently did release a report that included support for reducing the number of residency slots, so that detail is correct. But the decision wasn't made by them, and federal healthcare spending was already on the chopping block (and was a politically attractive area to make cuts given the Clinton's administration failed healthcare reform proposal).

As early as 2006 [4], the AMA started releasing policy position statements requesting caps on federal funding to be increased, but it wasn't until the CARES ACT in 2020 that Congress funded 1000 new CMMS funded slots were funded (but limited to small gradual increases each year) and started to be implemented in 2021-2022. And they continue to advocate for increases that so far haven't been adopted.

So while there's a kernel of inarguable truth that the AMA and other medical professional groups did support certain caps back in 1997, it has always been, then and now, a policy decision by Congress. With the motivation to set limits driven by concern over federal healthcare spending inflating budget expenditures.

But it makes for a simpler, emotionally resonant narrative of a shadowy self-interested group pulling the strings at the expense of the public (that also conveniently redirects outrage away from the people actually empowered to fix the problem, or that federal spending is a crucial lever to fix the problem).

Are AI labs training on the bike Pelican?

From the blog:

>The strongest argument is that they would get caught. If a model finally comes out that produces an excellent SVG of a pelican riding a bicycle you can bet I’m going to test it on all manner of creatures riding all sorts of transportation devices. If those are notably worse it’s going to be pretty obvious what happened.

Right now Always on Top options can be enabled only when you're not in the "attachment mode". Because when the app is attached to browser window it shows the sidebar only when it becomes active. I'll see if I can find some solution

As for importing from other browsers, this is definitely on my list (at least Chrome and Firefox). I just did Arc first because that's where I wanted to migrate from

Interesting approach. I built something similar (Komilion) — a model router that classifies each request and routes to the cheapest model that handles it well.

A few things I learned building this:

1. Price-only routing is not enough. You need quality signals too. I use LMArena and Artificial Analysis benchmarks to set quality floors per tier.

2. A regex fast path for simple queries (greetings, yes/no, translations) handles ~60% of requests in <5ms with zero API calls to a classifier. This matters because routing latency eats into your savings if every request hits an LLM classifier first.

3. Provider reliability varies wildly. Auto-failover saves you from the "DeepSeek is down" problem — your app keeps working, just on the next cheapest option.

One real example: a support bot went from ~$250/mo on Opus 4.6 to ~$40/mo with routing. Most conversations were FAQ-level.

Is EA(I assume they're the current IP holder of the game) losing sales from this in order for the violation to be noteworthy?

I assume there's not a huge untapped customer base for this particular game that were rushing out to buy it but stopped because it's also available online for free.

Nevertheless, i expect just like Nintendo, their lawyers will send a C&D just to defend the IP and trademarks on the basis of "use it or lose it".

On one hand there are places that will look out for job-hoppers so the 3yr rule is good. But for promotions, job-hopping is the best strategy.

The part people don't talk about much is the toll it takes on you when you switch jobs. It's like moving but worse. It's not like switching your wardrobe or something, it's a very drastic and intense change.

There really is no hard-and-fast rule with these things, you just have to figure out your industry, country, region and other details and determine what is best.

An advice I could have used earlier myself is the whole networking and building contacts thing. This is both internally and in your industry. There is literally nothing more important for your career than being likeable and building a reputation. Whether it's a promotion, better pay, or landing a better gig, focus on that as a priority.

In case what I'm saying isn't clear: be the biggest butt-kissing sycophant possible, and never be negative or disagree unless you're very confident that's absolutely what's expected of you by the right people. You don't get paid for how hard you work, you get paid for how valued you are. I think that's a bit obvious, but what many miss is that it isn't how valuable you are for the company that matters, it isn't even how valuable you are to your team, or to delivering some goal that matters. What matters is how valuable you are to individuals. Competency matters, but only as a 2nd or 3rd point of order. It matters how well you're liked, but also how good you are at improving how well-liked others are.

Sometimes there just aren't any opportunities where you are, nothing can be done about that other than jumping ship. However, expecting to be promoted, or paid more because of "the rules", that doesn't work well in real life.

Any guarantee made by manufacturer about data on tape longevity is irrelevant unless it is easy for user to create the storage conditions under which is warranted, and that is usually not cheap.

not hard to find stories about data on LTO tapes being unreadable after 5 years. The same as stories of data on even the worst CD-Rs being still readable after 30 years ( i can personaly attest to that).
by robinbanner | 2026-02-14 21:05:03+00:00
This is a nice approach — using model internals to predict success before committing to full generation.

We took a different path at Komilion: classify the prompt upfront (regex fast path + lightweight LLM classifier) and route to the cheapest model that benchmarks well for that query type. Simpler, but works without model-specific training.

The 70% cost reduction figure matches what we see in practice. The insight that most queries are "easy" is the key — once you stop sending FAQ-level questions to frontier models, the savings are dramatic.

Curious if you have looked at combining both approaches — upfront classification for obvious cases, then internal state probes for the ambiguous ones in the middle.

No. The specific strategy is not about using LLMs or polluting the internet. Enshittification is ... ah screw it, let's turn to wikipedia:

> Enshittification, also known as crapification and platform decay, is a process in which two-sided online products and services decline in quality over time. Initially, vendors create high-quality offerings to attract users, then they degrade those offerings to better serve business customers, and finally degrade their services to both users and business customers to maximize short-term profits for shareholders.

Fun fact, that obviously you already know but may be interesting to others.

In the encoding the registers are ordered AX, CX, DX, BX to match the order of the 8080 registers AF, BC (which the Z80 uses as count register for the DJNZ instruction, similar to x86 LOOP), DE and HL (which like BX could be used to address memory).
Show HN: Keyjump – a keyboard-first new tab for power-users
by kristianmitk | 2026-02-14 21:06:15+00:00
I built Keyjump, a keyboard-first new tab page for quickly jumping between bookmarks, dashboards, and predefined site searches.

I originally made it for myself during my CS studies because I was constantly switching between tools and wanted something faster than clicking through bookmarks. I’ve used it locally for years and recently cleaned it up and made it public: https://keyjump.app/

Main characteristics:

- Keyboard-first navigation

- Custom search templates (e.g. jump directly to search results on specific sites)

- Local-first: data stored in browser local storage by default

- No account required

- Optional account for cross-device sync and persistence (when clearing browser data)

- Chrome extension available (Firefox planned); it also lets you quickly save bookmarks/search queries from other tabs and launch an overlay on any page

- Theme and layout customization

It’s intentionally simple and focused. I’d appreciate any feedback or criticism.
by robinbanner | 2026-02-14 21:06:17+00:00
Nice dashboard. Cost visibility is the first step — you cannot optimize what you cannot measure.

We have found that the natural next step after tracking is automated routing. Once you see that 70% of your frontier model calls could have been handled by something much cheaper, you want a system that does that automatically.

At Komilion we route each API call to the cheapest model that fits based on benchmarks. The combination of monitoring (like this) + routing gives you both visibility and automatic savings.

One thing I would suggest adding: cost-per-quality metrics. Raw cost is not the full picture — $0.80/M tokens that fails 20% of the time is more expensive than $2/M tokens that works reliably.

I maintain an open-source project called Linkwarden and this exact discussion is one of the reasons why it exists, teams needed a way to preserve referenced URLs reliably without having to depend on external services.

It stores webpages in multiple formats (HTML snapshot, screenshot, PDF snapshot, and a fully dedicated reader view) so you’re not relying on a single fragile archive method.

There’s both a hosted cloud plan [1] which directly supports the project, and a fully self-hosted option [2], depending on how much control you need over storage and retention.

That is easy for optical drives, because there is no direct relationship between the size of bits on the optical track and the dimensions of the read/write laser head.

For magnetic media, the gaps in the magnetic circuit of the read/write heads are optimized for a certain dimension of the bits from the tape material and the efficiency of the read/write process greatly diminishes for other bit sizes.

So there is no obsolescence policy, but there is a real technical difficulty in ensuring compatibility with older magnetic media with different bit densities.

I personally dislike wearing isolated earphones for longer periods of time since they short-circuit the ear canal and I hear every bone in my jaw area and neck after some point.

3rd generation Airpods, while don't isolate, sound pretty epic for what they are. When sitting at home, I can listen to some music and genuinely enjoy it, and I like their non-isolating nature because it helps me to hear traffic around while walking with them. The only problem is, talking on the phone with them might get a little noisy for the other party, but I believe phone hardware filters some of it.

When compared to their rivals, they really have higher resolution, and enjoyable sound balance. Also, iPhone scans your ears with FaceID camera to profile them, so they are also tuned for your ears from get go. This makes positional audio really shine, too.

The original iPod buds were pretty flat and tinny. I used to use a pair Sennheisers (I don't remember the model but they were pretty high end) to be able to enjoy what iPods had to offer, back in the day.

Answering the question in the title...

> One study in 2020 found that 95% of asymptomatic patients had some type of "abnormal" finding, but just 1.8% of these findings were indeed cancer.

So a bit less than 1.8% of the time in this study

> Prenuvo's recent Polaris Study followed 1,011 patients for at least one year following a whole-body MRI scan. Of these patients, 41 had biopsies. More than half of the 41 were diagnosed with cancer.

That's 2.0%

Note that this doesn't mean that 1.7~2.0% of people have cancer without knowing it. It could be more:

> A negative scan doesn’t mean you’re disease-free. Some cancers and conditions simply aren’t visible yet or aren’t reliably detected on a one-time full-body MRI."

But also perhaps less, in a way:

> "You're finding something that never would have caused you any problem in your life, and in cancer, we call that overdiagnosis," Vickers says.

Russia has been among the top sources of spam since the early 2000s, it's not like anything changed lately. Mail-order bride scams and similar peaked in like 2005. It doesn't take a lot of people to send spam, I don't think it's correlated with the general population's online presence. I'd actually say it's quite the opposite: in 2026, Russia has never been more disconnected from the Western parts of the Internet than it is now (the Russian Internet watchdog blocks like 30% of foreign resources since a few years ago, while Russian IPs are routinely banned on Western sites after 2022, I can barely open anything without a VPN).

For that reason, and because of limited English proficiency, Russian netizens rarely visit foreign resources these days, except for a few platforms without a good Russian replacement like Instagram and YouTube (both banned btw, only via a VPN), where they usually stay mostly within their Russian-speaking communities. I'm not sure why any of them would be the reason the Internet as a whole has supposedly become low-trust. The OP in question is some SEO company using an LLM to churn out sites with "unique content." We already had this stuff 20 years ago, except the "unique content" was generated by scripts that replaced words with synonyms. Nothing really new here.

That's a great question; it's something I still need to explore, but it would involve some sort of distributed public key database and IP address directory, then a routing table on top of that as people add more resources to the mesh. Wireguard is particularly good at transparent roaming, so it's trivial to use on portable devices or if you need to migrate your server from one provider to another.
