A platform to host virtual races for fundraising events. Think Race Nights from the 90s/00s. Currently working on this with my brother, as we've both been out at risk of redundancy.

Had our first event over the weekend. Now we're focusing on marketing to local social clubs, charities and school groups.

Got a long list of future features and improvements, but this is a solid MVP. Made in react with redux, Pixi.js and prisma with sqlLite for a db.

Do you have any... sources?

> the whole federal government pissed off a good chunk of the country with DEI initiatives, codified by affirmative action, extra grant requirements, and ideological purity statements

Certainly there were affirmative action programs within the NSF, yes, but I think it's trivially obvious that they only affected a small minority of applications. RE:"ideological purity statements", I'm assuming this means stuff like affirming the vague concept of social equality and civil rights? If so, that's a goofy framing; the scientific process is seriously endangered by entrenched biases, which every human necessarily has on some level or another: https://plato.stanford.edu/entries/feminism-epistemology/

Regardless, I seriously question the idea that "a good chunk of the country" was actually "pissed off" by these things (much less anything at all involving the NSF and NIH programs, which most voters are only vaguely aware of). Lots of privileged people in this country continued to voice the exact same oppositions to social change that they have since the ~~1960s~~ 1860s, sure, and perhaps they have some valid points -- this isn't the place to really litigate that. But on an objective level, I find the idea that this is some justified reaction to post-2008 wokism to be fundamentally incorrect.

USAtoday is a propaganda rag. Gas powered tools are needed because electric tools still can't do large jobs very effectively. It has absolutely nothing to do woth proping up the oil industry. That's just a straw man used to push more control over your life and freedom of choice. Electric tools are 90% made of petroleum oil. They batteries are mined with petroleum oil. The batteries are charged by oil as well.

I'm having trouble decoding this.

The human emotion of spite is an attitude, not a permanent trait we call "evil". I've felt spite. You've felt spite.

I've never killed a national institution out of spite like these people are trying to do with academia. But I yearn to someday eliminate the Forbes 500 list. Does that make me evil? That's a judgement call. How much do you need the Forbes 500 list? How essential is it to your future well-being that those people keep on existing at their current level of wealth? Compare with academia.

> Society can't throw up its hands in shock as students outsource their thinking to simulation machines when fifty years of neoliberalism has masticated education into something homogenised, metricised and machinic. Meanwhile, so-called Ed Tech has claimed for decades that learning is informational rather than relational and ripe for technical disruption.

So university cannot effectively resist AI without resisting these ideas first. I hope it can be done.

This attitude means the shared institutions go away since the group you don't like doesn't want them to begin with and are a very large (possibly majority) of the people you have to share them with.

The only way to fix this is to apologize for the things you think are actually important and correct the mistake.

Alternatively if you really do deeply want these things you could acknowledge we can't share them, find some way to separate yourself, and go build them with like minded people and without the rest of the country. But that probably means finding or creating a different state to do it in.

Gallup doesn't poll capital but retirement accounts- a lot of those are invested in cash and cash equivalents - CDs, bonds, etc. That's not the capital-as-control which we're discussing here.

More importantly, the 401k-s invested in the stock market aren't capital either but they do provide intermediating third parties with controlling power without any assurance that it will be used in the interest of the account holders - pretty much like bank accounts work.

Thus, 401k holders are not holders of capital, they only notionally own a share of pooled assets which are controlled by third parties for those parties' own ends and connections - mutual funds, banks, etc.

having two very different code paths for measuring the length of the DER buffer and writing the DER sounds very scary. i guess its fine with Rust but the idea would give me the heebee-jeebies for any other language unless they are using a safe buffer implementation. i would find it hard to trust that there is no buffer overflow based on divergent behaviour between the two functions.

> once they get there they go back and return with women would be a reasonable guess.

Off-hand this seems like it'd require twice the time, resources, and risk. Without some strong theory as to why an all-male boat would be particularly useful (but not necessary on the return trip), occam's razor suggests to me that this is a much less likely theory.

FWIW, the oral history does indicate both men and women were part of at least the initial settling of new zealand by polynesians: https://en.wikipedia.org/wiki/Kupe. Even if this is entirely mythical, it does speak to the cultural understanding of settling.

you also could compare internal dimensions between 3: 2005 accord vs 2025 civic vs 2025 accord, I kinda believe 2025 civic will be closer to 2005 accord.

But I mostly referred on class in general: 2005 accord was basic appliance economy car, while 2025 accord has many more accura like luxury features besides drivetrain.

I've been basing one of the biggest financial decisions in my life - whether to buy a house - in large part on NYT/NerdWallet Rent-Buy calculators. But when I dig in, it seems that the model is both extremely sensitive to home/S&P500 growth assumptions, and that their defaults aren't well thought through.

This site is my attempt to organize my thoughts on what reasonable defaults should be, and provides an interactive tool to explore housing and S&P500 growth historical growth rates.

I'd appreciate feedback!

Unfortunately pharma has the US patent office in their pocket and they release most drugs in a default form and then when the patent is running out they make a slow release version and get a new patent on it. It doesn’t take them a dozen years to figure out how to make a slow release version, and another ten to come up with an extended release version.

I’m on an extended release generic only because it’s older than dirt.

First, while we have eliminated the "family wage", which was what allowed American working class families to be supported on one income alone in the 1950s, and we have made things like the housing market cost prohibitive, and wrecked community life, we also have different priorities today. For example, among those who can afford an annual vacation to the Caribbean or a new car or whatever, many would not be willing to give that up if they had to in order to have another child. Keeping up with the Jones's is a thing, and we simply view children as burdensome sacrifices that deprive us of empty self-indulgence rather than great riches and an occasion to grow as a human being.

Second, the obsession with finances is unjustified. What's "enough" to have a child? And will you ever get there? You might hit infertility sooner and then it'll be too late. Having a child is an incredible motivator, because you have a firm and clear and worthy purpose. Your whole life is rearranged, and in a good way. You have descendants and in that sense, you are not alone or the end of the line. When children are a mere possibility, mere phantoms that you hope to afford one day, you won't have the same drive, and it becomes easy to get sidetracked or fall into resignation.

It’s more complicated than you’re implying. University capital expenditures are rational decisions when they’re competing for a national pool of students backed by cheap debt. Parents care about the student success initiatives, students care about the multibillion dollar rec center. Given the way the current higher ed market is structured, the bloated administration and vanity dorms are thus actually revenue positive. They attract top students, especially from out of state, and with them a fat stream of tuition revenue. Just cutting their funding from the top, without looking at the other half of their revenue generation, is missing the point entirely.

Sure, but in that circumstance this seems like an even worse solution. This requires hardware as well as uptime on services that you have no control over.

In the scenario you are describing (disaster relief) the simplest solution is to use what is already available. That would be the cheap radar set that you bought for the purpose of being a radar set for the port, or simply asking to have access to any of the dozens of existing radar sets already installed on most of the boats in port.

My point is that this uses additional hardware and an outside dependency (transmitting cell sites or other RF sources) to replace very affordable, ruggedized, reliable, safety-critical hardware that already exists. If your port control needs radar, the solution is to get a radar, not to pioneer a new technology that is almost as good as radar when it works correctly.

I'm not going to argue against the veracity of what you're saying, but I would caution against cutting off our nose to spite our face.

I think what we're seeing is that there is obviously a need to rein in some of those corporate excesses you're alluding to, and try to protect the research core that we need to move the nation, and humanity in general, forward.

I am working on tcx-ls. It is quite niche, TCX is an XML file format used in sports tracking devices. Tcx-ls is a CLI that displays the information contained in the TCX file (like accumulated time and distance, etc.) in a more user-friendly way. I hope it is useful for many people.

It seems like no more than a year ago the prevailing narrative was problems with higher education and science: how predatory and insidious the student loan industry is, and how it traps people in a cycle of debt with special treatment from the government to not let them escape; the replication crisis revealing just how deeply flawed the incentives in science are, and how safeguards like peer review have failed to stop the slide.

And yet now that there's money at stake - not the money of those drowning in student loans, but those who benefit from the system - people come out of the woodwork to wax lyrical about the majesty of academia, championing its defense at all costs. Curious.

> most modern hybrids use the ICE at higher speeds for efficiency, right? What does that mean in terms of added complexity and reliability?

There’s a lot of tradeoffs involved which I’m not an expert on. However, ICE cars need an engine capable of low end torque and a good efficiency across a huge RPM range, hybrids can use a much simpler engine design optimized for where the engine operates best because the EV side handles the low end just fine.

A hybrid engine is also used for fewer hours of operation over its lifespan so in general (because exceptions exist) the gas engine in an hybrid is more reliable than the gas engine in an equivalent ICE. That said, car manufacturers can use up that margin to save weight etc so it’s not a guarantee.

In the end it’s a huge design space, saying something is a hybrid doesn’t actually tell you much about what’s under the hood.

I can kind of see the author's point, though I don't agree with it. AI is what made the problems obvious. Students didn't start cheating with the appearance of AI chatbots.

My view is that university classes should be taught in such a way that students can use AI as much or as little as they desire in order to learn the material. Evaluation should primarily be done in the classroom without access to AI. 90% of the grade in my undergraduate course comes from in-person exams. I don't care how they learned the material. This can be a problem for composition classes, for instance, but the problem existed long before the chatbots.

> AI is actually a giant material infrastructure with huge demands for energy, water and concrete, while the supply chain for specialised computer chips is entangled with geopolitical conflict. It also means that the AI industry will beg, borrow and steal, or basically just steal, all the text, images and audio that it can get its spidery hands on.

Sure. We don't know yet how the economics will play out. We don't know the actual cost of LLM and other AI services, we only know what companies are currently charging for them, but they're competing for mindshare so the prices are most definitely being held low. To a large extent, the whole thing has demonstrated what can be done in the short-term in the absence of copyright restrictions, and now we have to see the long-term effects of the removal of copyright restrictions.

I agree with many of the points in the article but don't understand how that turns into a recommendation to "resist".

This is really cool - it'd be great to test for other chemicals like heavy metals.

Specifically, rice seems to contain a good deal of arsenic (https://www.consumerreports.org/cro/magazine/2015/01/how-muc...) and I've been interested for a while in trying to find some that has the least, as I eat a lot of rice.

> This is actually a frequent occurrence. But honestly it usually doesn't come with that exact same phrasing. It usually comes with "let's spend our time on this other thing that isn't important but is new therefore important". It's true, sometimes you need to triage, but there's a clear bias that once something "works" (no matter how poorly) there is much less incentive to make it work not poorly.

Exactly. “It technically functions and therefore doesn’t need attention” has become an industry norm. There’s a massive bias towards piling on more features over making older ones good.

HN readers are, at least if they’re in sfbay, somewhat more likely to use a variety of drugs (prescribed or otherwise) and significantly more likely to have researched the beneficial and adverse affects of any drugs they take voluntarily, relative to a baseline default population. “Nootropics” preceded “Microdosing”, and the human fascination with optimizing oneself knows few bounds.

I suspect so. Evidence from multiple scientific and medical sources indicates a clear association between chronic alcoholism and a decline in IQ. Obviously correlation is not causation, and it's hard to argue we should do an RCT for drinking with any medical ethics board. But in the case of a small molecule neurotoxin like alcohol that so easily weaves its way into and through brain tissue, and with relatively easy-to-understand molecular interactions, it seems likely to be causal.

Alcohol and its metabolites directly harm and kill nerve cells, contributing to a reduction in brain volume. Here it's particularly important to remember that neurons, if they grow back at all, don't do so anywhere near the rate of, say, your skin cells. But it's also true that alcohol use can damage blood vessels, including in the brain. It's not hard to suspect that causes less efficient neural activity over time even if no actual neurons are killed.

I’m working on Great Rift Safari — an AI-powered platform that helps travelers design fully personalized safari itineraries in East Africa (think Kenya and Tanzania).

Instead of wading through endless lodge options, park fees, and confusing seasonal details, you just share your interests (big cats, birding, photography, budget, luxury, etc.), and our AI planner (plus input from local experts) builds a detailed, day-by-day itinerary for you.

We also show realistic price estimates and handle all the local logistics, so you can focus on the adventure, not the spreadsheets.

If anyone here has struggled to plan a safari (or has feedback on what would make it easier), I'd love to hear your thoughts!

> Here the term "same representation and alignment" covers for example the possibility to look at [...] one would be a structure and the other would be another structure that sits at the beginning of the first.

Does it? It is quite simple for a struct A that has struct B as its first member to have radically different alignment:

struct B { char x; }; struct A { struct B b; long long y; };

Also, accidentally coinciding pointers are nothing "rare" because all objects are allowed to be treated as 1-element arrays: so any pointer to an e.g. struct field is also a pointer one-past the previous field of this struct; also, malloc() allocations easily may produce "touching" objects. So thanks for allowing implementations to not have padding between almost every two objects, I guess.

Corollas in a High Cost-of-Living Area (HCOLA) that are ~3 years old, and under 30K miles, and all under $20,000. So... 20% or more off MSRP?

(The SE starts above $24k, the LE is a bit cheaper.)

I picked a hard example, but I bet for any car less popular and in demand than a Corolla (and in more normal areas), you can readily find them for 20% off MSRP at the 2-3 year old, 20-30k mark.

Most people have their phone in a pocket or purse or similar while outdoors. Wouldn't this require the phone to be out and exposed to light in order to work correctly? So not only are you trying to get people to change habits of getting outside, you're also requiring they change habits with the devices as well. Good luck with that, and I mean that with more sincerity than snark but not no snark.

So they voted to shut it down in 2015, which is a very different statement than it being shut down in 2015 (your original statement). And did they plan the shutdown to take place at this exact time of year 2025, or was the date not set back then?

It seems you also got many of the facts wrong based on replies from others anyway.

I know nothing about this particular one, just trying to understand what actually happened.

Yes? My tape measures are in the tape measure box. White metal cabinet, lowest shelf on the right, cardboard box marked "tape measures." There's a dozen or so tape measures in there. Same place they've been the last 30 years.

Making a custom enclosure for every tool seems over optimized and wasteful. If I were to attempt this, it would take decades and I'd never see a return on productivity within my lifetime.
Show HN: Dittofeed – Embed Messaging Features in Your App
by chandlercraig | 2025-06-30 17:03:00+00:00
Hi HN, Chandler from Dittofeed here. We’ve made a way to embed messaging features into any application because we saw a lot of engineers reimplementing the same things like drag and drop workflow builders, user segmentation builders, and template editors. This is especially true in vertical SaaS where you may have an app for healthcare providers, for example, and you want to give them communication tools to reach out to patients. It’s a non-trivial lift to build messaging features, and it can end up taking engineering teams 6-12 months to implement.

So now you can just consume any number of our embedded components as iframes and, by next month, as headless react components as well:

https://docs.dittofeed.com/embedded/getting-started

Looker was a strong inspiration for us, and it was apparent that messaging automation was in need of a similar approach. We have a range of companies that have successfully deployed our components to production, so it seemed like a good time to let the internet know they’re ready to use.

Although we’re an open-source company and our base product is free, these components are a paid feature. You can either use our self-hosted license or our cloud. Reach out to [support@dittofeed.com](mailto:support@dittofeed.com) for an admin API key if interested.

If you just want to use our MIT-licensed base product as an alternative to Klaviyo, Iterable, MailChimp, etc. you can find it here:

https://github.com/dittofeed/dittofeed

Would love any feedback you have!

Let me be clear: it shouldn't be about sides or ideologies, but recently in some places it has been blatantly about ideologies, promoted by one side while they were in power, and this has enraged the base of the other side, who have brought their side into power, and they approve of their side applying maximum ideological fuckery, possibly dooming us all.

A slight majority of people who ended up voting in the last election did vote for people who also said they were against DEI, yes. But

1. That really has nothing to do with what's going on. I feel comfortable saying that it is a plain fact that the Trump administration is not just pushing back against woke language or affirmative action, they are dismantling the entire scientific infrastructure. It's up to you to infer why (maybe for a good reason!), but denying that it's happening is doing yourself a disservice. That's of course not even mentioning how "anti-DEI" seems to be awfully close to old-school segregation in practice...

2. I think you're mischaracterizing the basic mechanics of referrenda. Again, without getting too far into political particulars, I think it's objectively true that "stop the woke" was only a small part of Trump's campaign, even if we grant that that phrase logically implies what's happening now. He spent most of the final months denying P2025, hitting "no taxes on tips" and "Trump == Safety, Kamala == Crime" hard, associating Harris with Biden & The Deep State, and, above all, talking about inflation and the price of eggs and "a new American golden age". Of course all voters should read up on everything a candidate says, but we know that's far from the case.

I am still amazed that humanity continues to depend on steam (water vapor) for majority of our energy production.

Essentially, everything boils down to (pun-intended): Heat + Water = Steam + Turbine.

Still, waiting for the day when we will get rid of the rotating elements, directly using charged or magnetic fields, harnessing the energy...
