I agree with the gist of what you are saying wholeheartedly. Always be prepared to be thrown under the bus by your employer, no matter how unlikely it seems... but that isn't really the message of the original blog post beyond the possibility space of the headline.

The actual contents are almost the opposite, the blog poster stayed around in their role for an entire year while letting their employer know they were unhappy.

I'm all for professionalism when leaving a job. For any full-time position I've held I've always followed the 2 week notice standard as a minimum and have even done part-time work past the 2 week period in a couple of special cases where I understood the burden on the company I was leaving was more than a 2 week transition could handle.

... but I don't see how it counts as being ready to quit at any time if that quitting is the result of the company not being able to fix a job situation you've told them isn't working out for you over the course of an entire year.

It depends. Overall, lowest all-cause death indexed on BMI seems to be around 27 plus or minus [0]. Interestingly, for all subjects (not just healthy non-smokers), BMI 30-32 isn't really associated with a dramatic increase in all cause mortality.

Obviously life is more complicated than just one measure. I figure this is just another data point saying BMI is useful for population studies and not great for individual diagnosis.

There is an old pharmaceutical product that was available in Germany, but can not be obtained anymore. Ouabain /Strophanthin

"Ouabain /wɑːˈbɑːɪn/[1] or /ˈwɑːbeɪn, ˈwæ-/ (from Somali waabaayo, "arrow poison" through French ouabaïo) also known as g-strophanthin, is a plant derived toxic substance that was traditionally used as an arrow poison in eastern Africa for both hunting and warfare."

It was later found naturally occuring in the human body:

Key Paper: Gottlieb SS, et al. "Elevated concentrations of endogenous ouabain in patients with congestive heart failure." Circulation. 1992;86(3):846-849. Details: Researchers measured plasma EO in 21 patients with severe heart failure (NYHA class III-IV), finding mean levels of 1.59 nM—over 3x higher than in controls. EO correlated inversely with cardiac index (r = -0.62) and positively with mean arterial pressure, but not with atrial pressures, suggesting a compensatory role in cardiac output regulation rather than simple volume overload.

The only problem on VAT is that it's regressive. People studied sales taxes until they solved every single of their problems, except for this, that in inherent to the activity. It's also the least regressive form of commerce taxes around, and the easiest one to mess with and so the government can take the worst impacts away.

And if you pair it with a capital movement tax, you can make it proportional. But we don't have anything equivalently good for capital movement, so most governments refrain from it.

Either way, if you want to argue that VATs are bad because they only tax one part of economical activity, that's an incredibly bad argument.

Getting shot? I think you might have stumbled onto the question of gun control. I wonder if that's ever been a topic of discussion.

Or if it's about black-on-black crime, maybe there's something to look into with affirmative action?

Cops against blacks? ACAB or kneeling at football games ringing any bells?

Sarcasm aside, one difference here is that the government is trashing your neighbourhood on your dime. You have to listen to republicans say there's no money for healthcare while they spend money on deploying troops to shoot priests with pepper bullets and trying to deport citizens.

If D has a separate feature for one of: generic types, interfaces and macros, then obviously it doesn't use partial evaluation similarly to how Zig does. It seems to me that it has all three: templates, interfaces, and string mixins. So if Zig uses its unified partial evaluation feature to eliminate these three separate features, why bring up D, which clearly does not eliminate any one of them?

It's like saying the the iPhone design wasn't novel except for the fact that prior art all had a keypad. But the design was novel in that it was intended to eliminate the keypad. Zig's comptime feature is novel in that it exists to eliminate interfaces, generics, and macros, and you're bringing up a language that eliminates none of them.

So D clearly isn't an example, but perhaps there's some other language I haven't heard of. Just out of curiosity, can a printf in D not only check types at compile time but also generate formatting code while still allowing for runtime variables and without (!!!) the use of string mixins? Like I said, it's possible there's precedent for that (even though it isn't the distinguishing feature), and I wonder if D is that. I'm asking because examples I've seen in D either do use string mixins or do not actually do what the Zig implementation does.

With the first iPhone Steve Jobs wanted a web based future. Then jailbreaking got us native apps and AppStores and the rest is history.

I still remember my Nexus One running flash!

Anyway, I wonder if the web path would’ve been the chosen one, how Apple would’ve played the web standards that are crippled today especially on Safari.

>Children don't get 'rich feedback' at all on the grammatical structure of their sentences.

They probably do get parents and the like correcting them or giving an example. Kid says we goed fish, adult say yeah we went fishing. I taught English as a foreign language a bit and people learn almost entirely from examples like that rather than talking about ellipsis or any sort of grammar jargon.

It seems brains / neurons / LLMs are good at pattern recognition. Brains probably quicker on the uptake than LLM backpropagation though.

I've been selfhosting my own to avoid this issue. Once in awhile a search provider will be unavailable but its pretty consistent in pulling in the major ones.

There is nothing to "misunderstand" here, this is not algebra but law, and law often erects artificial and arbitrary barriers in the middle of things, in order to further some specific interests or agenda.

The closest analogy I can find is the concept that commercial speech deserves less protection than private speech.

It is a matter of opinion and prevailing mores. In my opinion, becoming an employee is a voluntary decision (unlike, say, being drafted into a war), and should be treated the same as becoming a trade union member or a volunteer in a church organization.

Why make a special language? Just use HTML and TypeScript that will be compatible with editors, tooling, etc. This is the same mistake Imba made.

It's a shame because the core of Marko looks phenomenal: streaming, fine-grained bundling, rendering performance, etc.

Also not sure about the file-based routing of Marko Run. That was a big reason why I abandoned SvelteKit.

Does that include housing? I went and read the Swedish Wikipedia birth rate article (Födelsetal), but couldn't find any clues. Social norms, that's about all.

Presumably the worrying thing here is a possible boom-and-bust cycle. In the long view it should be self-limiting, if a small population with lots of space tends to fill it with a larger future population that then reproduces less. It's just unpleasant to be caught at the declining stage of that cycle, with abundant old people.

Yeah, I know that Upset Plots are a better choice for data visualization — as everyone is pointing out — but take a moment to appreciate this beautiful etude for what it is. This nicely executed. I love how this forced the author into some very difficult choices about how to create a large set of convincingly "mixed" colors — which is a very difficult problem even with just 4 overlapping base colors!

In some sense, they "lucked out" by dealing with a prime number of primary color sets, which helped them avoid having multiple pairs of colors that are directly across the wheel from each other.

Very nicely done. It's fun to play with, and inspiring to study.

Heart disease is the leading cause for death, but the root cause is definitely obesity. There’s a an obesity-pandemic that no one’s talking about it, there should be a national program that encourages people getting fit and discourages them from getting obese. And by encouraging/discouraging I don’t mean some random posters posted around, no, things like tax cut for fit people, free access to xyz if your bmi is less then abc, cheaper flights and insurance if you are fit, and so on.

This was a nice surprise. It looks simple but it does the job. It allows me to put my pics and videos on my private cloud. My pdf also and search is fun. It allows me to create markdown docs too. A simple docker install and you have your private cloud. Top! It is not NextCloud. Nor it pretends to be. I like it, might keep this running and maybe put it to work. Thanks.

Even more basic, I will often use the Lookup option in the macOS right-click menu to get a quick definition just to make sure I have the right spelling correction. If it’s a correct spelling of a wrong word, that can be harder to find later and difficult to remember the intended word later.

For example…

Whether - expressing a doubt or choice between two alternatives.

Wether - a castrated ram

That one letter makes a big difference.

Not the OP, but:

This is actually a thorny problem.

Say you have an advertising system that knows nothing about a user’s gender. This system, by construction, cannot vary its ad selections based on gender. But the system does remember whether users have expressed interest in the ads it has previously shown them.

Now say you have a job that in general appeals to one gender almost exclusively. The system will, given time, learn which users are interested in ads for this job. Those users will just happen to be almost exclusively of one gender.

If the ad system stops showing ads for this job to the users who have demonstrated they don’t want to see them, is that gender discrimination?

One can make an argument either way. But either way, it’s not going to be a clear-cut argument. There’s some subtlety required.
by inglor_cz | 2025-11-08 22:08:47+00:00
This is basically just a consequence of people being a long-lived species.

The question is whether the side effects of artificially speeding up the process won't negate the original intent.

Also, the very fundament may be wrong. The authors of anti-discrimination statutes seem to be awfully certain of things such as "men can take care of babies in nurseries equally well as women can". We do not know if this is, in fact, statistically true. It is more of an egalitarian article of faith.

Thanks for the feedback on the raku.org site. We like sigils $ for one thing (scalar), @ for many things (array) and % for dictionaries (hash). The linguistic idea is that such words stand out as “nouns” in contrast to all the routine names which are “verbs”. In practice, after you get familiar, it really helps code to be written in an expressive way to better convey the intent. Sure, if sigils makes you glaze over then maybe it’s not for you.
by jiggawatts | 2025-11-08 22:11:27+00:00
All fair points and obviously well thought out by knowledgeable people. I approach problem solving the same way, accounting for staff familiarity with tools, not just the wall-clock time taken for some esoteric approach.

My observation is that in the last year or so the relative weight of these contributions has shifted massively because of AI code authoring.

It’s so fast and easy to whip up a few hundred lines of code with something like Gemini Pro 2.5 that I got it to make me a sorting benchmark tool just so I’d have a data point for a comment in this thread! I never would have had the time years ago.

For relatively “small” and isolated problems like password hash lookup tables, it’s amazing what you can do in mere hours with AI assistance.

If I was approaching this same problem just two years ago I would have picked SQL Hyperscale too, for the same(ish) reasons.

Now? I feel like many more avenues have been opened up…
by fragmede | 2025-11-08 22:11:41+00:00
In AI though, you also have the world trying to compete with you, so even if you do totally cheat and put the benchmark answers in your training set and over fit, if it turns out that you model sucks, it doesn't matter how much your marketing department tells everyone you scored 110% on SWE bench, if it doesn't work out that well in production, your announcement's going to flow as users discover it doesn't work that well on their personal/internal secret benchmarks and tell /r/localLLAMA it isn't worth the download.

The Surface Go 2.

I wanted to combine my MacBook, my notebook and my books to reduce my pack size, since I travel a lot.

It spent a full 24 hours doing software updates. Then I realised that nothing kills the joy of sketching like the file save dialog when you want to close the app. It was also a lousy laptop and a bad ebook reader. I returned it on day 2.

I got an iPad Mini instead. It's one of my favourite objects.

Notably, Chris Sacca (now a famous VC), when working at Google in the early 2000s, got in trouble for mentioning that telecoms were preventing Internet from being Net Neutral, and instead of being fired, he got promoted by Larry Page and given a huge budget to work on it. I can't find a reference but I'm almost certain this is correct.

The point of these LLMs is to do things that computers were bad at.

That's a good point imo but we achieved this stuff by at least 2022 when ChatGPT was released. The thing about these giant black boxes is that they also fail to do things that directly human-written software ("computers") does easily. The inability to print text onto generated images or do general arithmetic is important. And sure, some of these limits look like "limits of humans". But it is important to avoid jumping from "they do this human-thing" to "they're like humans".
ECommerce – CAC keeps rising, so we built Evolvoom.io to fix it
by evolvoom_io | 2025-11-08 22:13:08+00:00
We started our business journey in 2022, running our own eCommerce stores. Early on, we realized something simple but powerful — it’s way easier to sell again to people who already trusted you than to chase new customers through ads.

But acquisition kept getting more expensive, and our retention marketing just didn’t deliver. Even with discounts and email flows, ROI was weak — and tools like Klaviyo weren’t cheap.

So we went manual. We analyzed each customer’s purchase history, behavior, and preferences, then wrote personal messages with relevant products and offers. Those manual campaigns converted at ~40%. But it wasn’t scalable.

That’s why we built *Evolvoom.io* — an AI-powered email marketing employee. It connects to your Shopify store (we’re official Shopify Partners), syncs customer data, writes personalized campaigns on the fly, and sends them automatically. It even replies when customers respond.

The technology is powered by *OpenAI*, and we’re also a *registered TCR Campaign Service Provider (CSP)* — meaning we don’t rely on third-party SMS gateways. This lets us stay competitive on costs and maintain higher margins than typical outbound marketing SaaS providers.

We’ve already built the full platform, ran multiple small beta launches, and are now preparing for our public rollout focused on paid users and brand awareness.

From a market standpoint, we’re operating in the *B2C e-commerce space*, valued at around *$5.47T in 2023* and projected to reach between *$17.7T (by 2030)* and *$37.7T (by 2034)*, growing roughly *~19% annually* (Grand View Research, Precedence Research). The *dropshipping segment* alone is expected to surpass *$1.2–2.0T by 2033 (CAGR ~22–23%)*. With rising acquisition costs (+222% since 2016) and an average retention rate of just 31%, the gap in customer loyalty is only widening.

We built Evolvoom for that gap — a system designed by ex-store owners who were tired of wasting time and money on tools that didn’t scale personalization.

In short: *Evolvoom is retention on autopilot* — it writes, sends, and replies so you can focus on growth instead of manually managing marketing.

We’re sharing this here because this community understands what it means to build fast, test hard, and learn quickly. Would love to hear thoughts from other founders on: - Building SaaS in saturated markets but with new positioning (retention vs. acquisition) - The tradeoffs of AI automation vs. authenticity - Managing go-to-market strategy while keeping margins healthy as an early-stage startup

Here’s a short 60-second demo we filmed for our beta-testers that explains how Evolvoom works:

That requires people feel he is trustworthy, so he thinks (I don't believe him) this rhetorical pivot is essential to earn youth trust.

They all been doing this; Zuckerberg with his Macklemore style update.

Not sure I get the pearl clutching over surveillance state; look at social media being used to cancel. Journalism and its history of reaching into everyone's lives. Religion's history. Self organizing groups surveilling the population are normal.

Everyone is a self selecting biology out to demonize and denigrate, insulate itself with prestige. In the end all of it is some form of randos trying to surveil and track people. The one exception I make is healthcare, spread of illness. The rest is mostly self aggrandizing nonsense.

First worlders with zero obligation to engage in manual labor to serve their biological survival have little to do but hallucinate up crimes, sins, immoral behavior perpetrated by others.

The only people we should be canceling and harassing are in Congress. Yet purity competitions about powerless neighbors rule Main Street. The American social cult is nothing but hypocritical randomly existing meat suits abusing 12-13 year olds in third world textiles sweatshops; from billionaire class down to retail cashier.

The corruption is getting baked into the entire datasphere.

Funny if e-coins might have to die because the data stores become irredeemably polluted.

Meanwhile the LLMs are ingesting all of it into their matrices, implying corruption has become meaningless.

Today you can have a Microsoft Windows installation that constantly fails during auto updates due to config logic issues, where updates keep installing and rolling back, but you can't turn off updates and the only information provided is "Installing", "You're almost there 97%", and "Oops, something didn't go as planned, but don't worry we'll try again".

The criteria of proper system functioning is now arbitrary, yet "don't worry" that all your infrastructure and appliances are constantly modifying themselves.

Show HN: VitalLens 2.0 – A new SOTA rPPG model for HRV estimation from video
by prouast | 2025-11-08 22:15:22+00:00
Hi HN, I'm Philipp, the solo founder of Rouast Labs.

I've spent the last couple of years working on a new rPPG model, and I just published this blog post (which links to the full technical paper on arXiv) about the 2.0 version of my VitalLens API.

The main breakthrough is that the new model is now accurate enough to robustly measure Heart Rate Variability (HRV) metrics (SDNN, RMSSD) from a webcam feed, not just heart rate.

The blog post covers the new model architecture, the 1,400+ person training dataset, and performance benchmarks.

I'm here to answer any questions about the model, the tech, or the challenges of building a bootstrapped API.

Thanks for checking it out!

Apparently late 19th to 20th century wind cargo ships had their crew essentially subsidized by the fact that some countries (IIRC in Scandinavia?) required commercial sailing experience to get a pilot's license. For bulk cargo (e.g. grain or guano) the economies worked out.

I love that they're trying this. It appears the more practical goal might be retrofitting existing vessels with large sails to augment the motors, but making a point with a fully wind-powered vessel is a good show. Well, it would have been fully wind powered if not for the damaged sail. Good on them for sticking with the journey, though. I hope they keep running the vessel and get a few more fully wind powered journeys.

There's a big difference between first-order and second-order effects. If you explicitly check the box that says "show this job only to old white men" then we can prove your intent was to discriminate. If you advertise at a golf club, we have no such proof.

Also, unless the golf club is discriminating, female golfers are just as able to see the ad -vs- male golfers.
