The writing is quite Claude-y. I don't know if it's just me, but Claude models spend more time talking about their feelings to me than they do giving me smart answers.

> And honestly, this is mainly on me. I’ve fallen behind on maintaining my own collection of tasks that are just beyond the capabilities of the frontier models. I used to have a whole bunch of these but they’ve fallen one-by-one and now I’m embarrassingly lacking in suitable challenges to help evaluate new models.

> “Here’s an example prompt which failed on Sonnet 4.5 but succeeds on Opus 4.5” would excite me a lot more than some single digit percent improvement on a benchmark with a name like MMLU or GPQA Diamond.

Just because you say it's piracy doesn't mean it is.

When they provide all the equipment necessary to watch the content, and pay for the internet connection and power to my house, only then will they have a claim to what commands are run on my computer.

But my computer, that I paid for, using the power and bandwidth that I pay for, does not play ads.

If they don't like those terms, they can feel absolutely free to not send me any content they don't want me to watch.

Penlock is a printable paper calculator that enables users to split a seed phrase into a secure 2-of-3 backup. It is open-source, uses straightforward and robust cryptography, and incorporates multiple fail-safes to protect against human error. It also teaches how to use that backup to set up offsite recovery and trust-minimized inheritance, independently of any company, service, or software.

If you're approaching it from a "semantic pixel peeping" perspective then yes, I understand what you mean. It's a pretty clean bite... but it's important to remember the context in which most images will be assessed.

Earlier this week I did some A/B testing with AV1 and HEVC video encoding. For similar bit rates there was a difference but I had to know what to look for and needed to rapidly cycle between a single frame from both files and even then... barely. The difference disappeared when I hit play and that's after knowing what to look for.

For anyone curious: if you are targeting 5-10 Mbps from a Bluray source AV1 will end up slightly smaller (5-10%) with slightly more retention of film grain in darker areas. Target 10 Mbps with a generous buffer (25 MB) and a max bit rate (25 Mbps) and you'll get really efficient bit rates in dark scenes and build up a reserve of bandwidth for confetti-like situations. The future is bright for hardware video encoding/decoding with royalty-free codecs. Conclusion: prefer AV1 for 5-10 Mbps but it's no big deal if it's not an option.

One subtle thing worth adding is that display: contents also changes how accessibility trees are constructed. The element is removed from the visual layout and from the accessibility tree in many browsers, so semantics like list grouping, landmarks, or ARIA roles can disappear unless you re-introduce them manually.

That’s why subgrid ends up filling a different niche: you preserve the DOM structure, preserve accessibility semantics, and still let the children participate in the parent’s track sizing. It costs more than contents, but it avoids a lot of the accidental side-effects that show up once you start mixing layout, semantics, and interactivity.

I work as a custodian lead and our custodial staff has long dreamed of an app called "Poopalert". What Poopalert does is use smartpipes (toilet drains equipped with smart device tech such as employee biomedical health monitoring) - so it uses smart pipes to see if there is an unflushed toilet. Then are staff will go flush and clean, so the next guy gets the proper clean experience, and we dock the phantom shitter a small premium for the service which goes to our bonus pool. Anyway, with the smartpipes we can also tell if an employee is unwell or a risk, basically assess their healthy status, and cull the herd so to speak by firing the bottom 10% least healthy workforce.

This will lead to an organization of obedient, respectful, team players, all of which are very healthy - and make our custodial duties - or doodies as it were - much easier!!

This was underwhelming. I work with Python and Pandas, and I can show examples of much clumsier workflows I run into. The most often, you get dataframe[(dataframe.column1 == something) & ~dataframe.column2.isna()] constucts, which show that python syntax falls short here, and isn't suitable for such manipulations. Unfortunately, there's no alternative, and I don't see R as much easier, there are plenty of ugly things as well there.

There's Julia -- it has serious drawbacks, like slow cold start if you launch a Julia script from the shell, which makes it unsuitable for CLI workflows.

Otherwise you have to switch to compiled languages, with their tradeoffs.

I agree. I got really tired of hearing tables are for tabular data! For 20+ years. My reply was always, Who cares if it accomplished the layout you want. If the meaning of a word is what got people so hung up... why not go and make a new css term that did what tables did but improve on it. Now 20+ years later, that is pretty much what they did.

There was an AMA about conjoined twins on Reddit a couple of years ago, and one of the interesting parts was that they could each sense how the other twin is feeling in terms of emotions. This is due to a lot of emotional states being based on hormones that flow through their shared blood stream.

Depends on what's wrong, and how much a person's free time is worth.

The panel? No. The panel was the singular expensive part, and the cheapest and most available way to get a new panel is usually to buy it in a retail box with the rest of the monitor already wrapped around it.

The backlight tubes? Surprisingly enough: Yeah, if a person really wants to do that, and if the display uses fluorescent backlight, then sometimes the tubes are replaceable. (LED backlight is basically ubiquitous on newish displays and is, AFAIK, kind of a non-starter to dig into repairing. But it might be do-able by swapping bits from a broken panel if one were sufficiently motivated.)

Power supply bits? Sure. It's just a power supply, right? Power supplies are often repairable or replaceable. (I've repaired power supplies in LCD screens myself, and I'm pretty lousy at component-level troubleshooting.)

Broken connectors and switches such? Very repairable. (Difficulty depends a lot on how much, if any, of the board also got destroyed, but generally speaking hot air soldering is a lot easier than it looks like it should be.)

Mechanical issues, like a wonky stand or broken housing? Often repairable. (The screen I'm writing this with has a cast zinc base that broke due to metal fatigue. I've fixed it twice: Once with two part epoxy, and a second time by adding CA glue when the epoxy's grip on the zinc failed.)

Just to go off of this, I used to be a huge unix zealot - pipes, fork(), all of it, init, zombie processes.

I felt like systemd was an epiphany. Software doesn't need to a collection of simple tools that do one thing really well. You can have one tool that does everything shittily, the pdf reader of init if you will, and that's systemd. The author went on to do brilliant work with pulseaudio, you know, the whole /dev/dsp everything including sound is a file, oof. Let's make it a weird complex server process, oh, and let's make another sound system after that too.

I was very happy to see Lennart Poelering had joined microsoft to bring his brilliance to windows. I'm sure he's just cranking out masterpiece after masterpiece of design for them. I actually switched from unix to windows after being so inspired the tremendous quality and sensical design of both pulseaudio and systemd. Oh, and both very reliable, simple, and intuitive.

Thats interesting if true, but my cause to doubt it is that I have seen shops catering to the labubu format, that is the expensive mystery box toy, popping up with heaps of varied stock. In fact they dont even seem to center the labubus. Labubu might go away but I think its cultural significance of tiktok 200 dollar toy unboxing is going the distance.

PCI itself is Payment Card Industry. PCI DSS as noted is the Data Security Standard.

https://en.wikipedia.org/wiki/Payment_Card_Industry_Data_Sec...

The time it was in the transition between 2.0 and 3.0 (its been refined many times since).

https://listings.pcisecuritystandards.org/documents/PCI-DSS-... is the 3.2.1 audit report template.

One of the most important things in there is you don't mix dev and production. The idea of putting a development box next to a production box that runs the same transactions... that just doesn't happen.

Failing a PCI DSS audit means hefty fines and increases of transaction fees (paying 1% more on each transaction done with a credit card can make a $10k/month - $100k/month fine a rounding error) to a "no, you can't process credit cards" which would mean... well... shutting down the company (that wouldn't be a first offense - its still not something you want to have a chat about with accounting about why everything costs 1% more now). Those are things that you don't want to deal with as a developer.

So, no. There is no development configuration in production, or mirroring of a point of sales terminal to another system that's running development code.

Development code doesn't touch other people's money. We had enough side eyes looking at the raw data for our manager's payment card on development systems because only people that banked at that local bank occasionally experienced a problem with their visa check card... https://en.wikipedia.org/wiki/Digital_card#Financial_cards - when it says "generally '^'" it means it can be some other character... and it was... and this wasn't a problem for most people, but it turned out that the non-standard separator (that we only found after reading the card's raw data) and a space in the surname would result in misparsing of the track and giving an error - but none of our other cards used a separator that didn't match the "generally").

So, being able to generate real production load (in the cafeteria) without using Visa, Mastercard, etc... was important. As was being able to fall back to using the nearly antique credit card imprinter ( https://en.wikipedia.org/wiki/Credit_card_imprinter ) for the store that was lucky to get a dozen transactions a day.

That might be true of handbags, I am doubtful it is true of dolls. A handbag is a necessary accessory and has been for decades. The popular brands grew their way there slowly over many years. A company that explodes into popularity suddenly for a product people never knew they needed is likely to only stay in the spotlight for a short while and is best served taking advantage as best they can.

Yes and no. <table> layouts were a hack that solved a real problem but came with massive downsides. People didn’t tell you to not use <table> to lay out content because grids are bad (they are quite handy! take a look at Grid Systems by Josef Müller-Brockmann) but because <table> both posed technical and accessibility problems. A layout grid is not a table (or a <table >). A table (with and without <>) comes with attached semantics, hierarchy, reading direction etc. and is extremely rigid, which makes it a bad fit for differing screen sizes.

It’s true that this was a blind spot for a long time and that it was frustrating to not be able to efficiently lay out content in 2D when <table> was just there. But it was the wrong choice then as it is now and it has been baseline available for 8 years now. I hope it won’t take another 8 years until the comparison stops :o)

> I've fed thousands of dollars to Anthropic/OAI/etc for their coding models over the past year despite never having paid for dev tools before in my life. Seems commercially viable to me.

For OpenAI to produce a 10% return, every iPhone user on earth needs to pay $30/month to OpenAI.

Previously there was way more monoculture I feel. Everyone knew the big youtubers, Smosh, Pewdiepie. Everyone was playing the same flash games. I guess there is still a monoculture in online gaming with everyone centralising on a few top games. But youtube is completely individualised now.

Two users on TikTok are seeing entirely different trends and creators.

I don’t understand the point of concentrating everything in a megacity. Take New York as an example: the cost of living is through the roof, while the quality of life is often the opposite. Corporations should stop renting offices in the most expensive areas of the country and instead prioritize locations where housing is affordable and people don’t have to spend more than 10 minutes commuting to work. The state should de-prioritize NYC and encourage companies to invest in smaller cities. This would bring jobs to those areas, reduce pressure on NYC, and support broader infrastructure development. Apply that approach across the country, and suddenly the entire nation can function more efficiently instead of relying on a few overloaded hubs.

> IQ tests measures nothing more than the ability to pass an IQ test

Incorrect, IQ is a composite measure correlated with fluid reasoning, crystallized knowledge, working memory, processing speed, and spatial ability. It's true that you can't naively use IQ to compare two diverse groups, but you can correct for this with a large enough sample of any two groups. This idea that it's biased towards western culture or education is vastly overblown.
Show HN: RankLens – Track your brand's visibility in AI answers reliably
by digitalpeak | 2025-11-26 05:00:34+00:00
We built RankLens because we couldn’t answer a simple question for our own clients: “How often do AI assistants actually recommend your brand vs. competitors?”

Instead of ad-hoc “SEO prompts”, RankLens uses structured entity-conditioned probes. Each probe is defined by a brand/site entity + intent, and we resample across many runs to reduce prompt noise and random LLM variance.

For each probe we track: – Explicit mention of your brand/site (Brand Match) – Precision of when you’re recommended as the answer (Brand Target) – How often competitors get recommended instead (Brand Appearance + share of voice)- - Likelihood of being recommended by the AI. (Brand Discovery) – A prominence / “confidence” score for how strongly the LLM backs that recommendation

We combine these into a visibility index so agencies and brands can: – See AI visibility trends over time – Compare engines (e.g., ChatGPT-style assistants vs. others) – Spot when they’re losing AI “mindshare” to specific competitors in regions/locale

Method & code – We open-sourced the entity/probe framework as RankLens Entities (code + configs): https://github.com/jim-seovendor/entity-probe – We also wrote an in-depth study, “Entity-Conditioned Probing with Resampling: Validity and Reliability for Measuring LLM Brand/Site Recommendations”: https://zenodo.org/records/17489350

I’d love HN feedback on: – Weak spots / blind spots in the entity-conditioned probing methodology – Better baselines or evaluation strategies you’d use to test validity & reliability – Any ways this could be gamed in practice (e.g., by changing site content or prompts) that we haven’t considered

Happy to go into implementation details (sampling design, resampling, scoring, engine differences, etc.) in the comments.

Kinda. It's like like an in-group status signaling that "i discovered this before it became popular". As mentioned above, some sort of being a "hipster", but with fast-changing trends. To my understanding, it's done less consciously. Think of "oh, there's a new restaurant in town, we should check it out" idea, and people standing in a line waiting to be one of the first "to taste it".

> The firm gradually grew more contentious, demanding that the RTX 5060 be handed in because the event it was acquired at was part of a business trip, entirely paid for by the company. The employee would never have won the GPU had the firm not enabled him to attend the venue. Our winner refused, arguing that it belonged to him because he had won it on his own by pure luck.

Hmm...I feel like the company's reasoning here is almost acceptable. Almost, because I know as a (paid) employee, all of the code I write, any inventions or IP I come up with are the company's property, so it almost makes sense that the company might also want to assert its right to claim that any physical things given or gifted in the course of work-related trips that employees take on company time.

but the article mentions the winner was an intern, not an employee, and I know many interns i've worked with never actually signed an employment agreement, because they dont actually get paid. They sign NDAs but not full on employment agreements, so how can any company treat them like an employee? if I wasn't getting paid, I'd 100% hold my ground like the intern did and take it.

I loved the FAQ question "What happens if cloudflare is down?"... Well, the short answer is it takes down 75% of the internet with it; you mean like 3 days ago for the whole day? well, there is always going outside and going bowling with your friends for a few hours until it comes back online, then the internet resumes function at that time.

Specifically for org, and specifically for org-roam, it's pretty good, but not good enough. It's not as good as desktop emacs, and it's also somehow not as good as a 1st class android app.

the fdroid build of emacs doesn't really work very well with my org-roam, so i use a termux build,,, well nix-on-droid+emacs-overlay... and it's fine, for capture and recall. but i'm not authoring a lot of text with it. a custom extra-keys in the termux config so that your common emacs keybindings are on screen in a tool bar can get you close to a point-and-click interface... but you don't really have a good "swipe" input or voice input to input text efficiently, it's a character interface, a TUI, which is actually not what you want on a phone, you want a word-based interface. so when i want to do org-mode right now, i pull a unihertz titan 2 out of my pocket. without a sim card, the titan battery lasts for about three days unless i fire up an nix devShell & lsp server on it.

calc-mode is my default android calculator tho.

tbh don't listen to me, though: i've been teaching myself 8vim[1] and building a markdown document graph database in my free time. don't listen to ~any emacs user's opinion with any authority, we all have found our own local minima, our opinions and advice usually aren't so useful to each other

I didn't know about modified-bar-mode, though, that's neat.

Yes, this plugin is aimed at the long tail and I need to be clear on a fair use policy. The idea behind the self host worker is that I can provide white glove migration if any site becomes burdensome without disrupting the service altogether.

And I agree, if a site is behind Cloudflare DNS this plugin does not make much sense, but it's a solution for many non-technical users, as you mentioned.

Is it?

The notion of algorithms and computer science were invented to discuss the behavior of infinite sequences: examining if there’s descriptions of real numbers. This was extended by connecting complicated infinite structures like the hyperreals with decisions theory problems.

That descriptions of other infinite sets also corresponds to some kind of algorithm seems like a natural progression.

That it happens to be network theory algorithms rather than (eg) decision theory algorithms is worth noting — but hardly surprising. Particularly because the sets examined arose from graph problems, ie, a network.

Has union labor resulted in measurable improvement in production outcomes in any industry they’re found in? I don’t think going from “managers are unaccountable for failure” to “nobody is accountable for failure” is a good thing.

I think introducing more competition at higher levels may be better than eliminating it below. This should be happening because I’m pretty sure most PMs could be replaced by an LLM.

>Not sure what this technique is called or how it's done

Downscaling/downsampling attack.

Commonly used against AI systems either to pass filters or poison data.

https://arxiv.org/abs/2010.02456

If you know the sampling rate of the sampling filter you want to pass you can do some tricky encoding to show a different image at that particular resolution bypassing AI/content recognition systems. This said if it starts happening a lot Google will take those images/videos and feed them into a learning system that looks for those patterns and preemptively marks the video.

Have it in Japan too. You can clearly see eras in house design. Pre 1960 almost everything is wood. Then you have wood and plaster until the 2000s or so, and after that is plastic on wood. You can see the age of a neighborhood and its residents based on what houses are made of.

If the residents die and someone new purchases the land, the old house is (generally) torn down and a new one built.

Is any datacenter's water use significant compared to other industrial installations? According to that article, all datacenters in North Holland use 550 Ml/yr. North Holland has 2.95M residents [0], who use 129 l/person-day [1], 47 Kl/person-year, 139,000 Ml/year for the whole region. So the data centers use an estimated 0.4% of the region's water. Data centers use about 3% of the Netherlands' electricity.

Why do you think this is a lot of water? What are the alternatives to pulling from the local water utility and are those alternatives preferable?
