> what is literally snake oil.

Well it is this part that I'm unconvinced. You can probably gather from my comment that I fully believe they are overselling, but that's different.

As for the administration part, that's an orthogonal conversation. It is preying on the effects that I discussed, so they are related, but that doesn't mean they're the same thing. We can talk about the x-axis without the y-axis, even if we want to figure out where a point lies in a plane.

> We are so strapped for cash

I'll refer you to the first part of my comment.

Personally, when you're strapped for cash I think it is best to go after the big ticket items that are costing you money rather than freaking out about losing a few pennies. You're not wrong that allocation is a problem, but allocation is a difference between lack of budget.

I am curious to identify what your users are perceiving that isn't be being captured by your metric. If it is accurate and not just rhetoric that MOST of your users are asking for a rollback for purely performance reasons, that is a very extreme outcome.

Are your p90 metrics testing:

- navigation after first load?

- users who are going to the app after it is cached on their browser?

Are your actions going through server actions or rest apis? Do you have metrics on those?

It's not a bid deal but... I've become interested in low level programming some time ago. During past 5 months I've been working (not with the diligence I wanted) on a GameBoy emulator written in C++. It started with me trying to emulate the gbz80 chipset, then the "why not?" question did hit my mind.

Actually I have finished the CPU fetch-decode-execute cycle, so I'm implementing the CPU instructions and looking forward to implement a basic version of the MBC and get cycle accurate.
Show HN: Investment Catalog
by graham1776 | 2025-07-27 22:42:11+00:00
I am a commercial real estate executive who has no business posting to HN, yet I love this community and why not show off a project?

Working in finance often gets you the question "What should I invest in?"...which is kinda like going to a friend and saying what should I eat?

So over the years I've collected hundreds of types of investments across many categories and they lived in an excel sheet. And now I've brought it to life to share with you all!

Also added a fun little "allocations" page which shows how major investors allocate to these categories.

Have fun finding weird and wonderful things to invest in and let me know what is wrong or missing.

NASA is “the elites” in a key area: they’ve done a ton of research confirming climate change is real and impactful. I think the general antipathy for education intersected strongly with the wing of the Republican Party which sees climate change as the enemy both because many of them are funded by fossil fuel companies and because they see all forms of collective action or addressing externalities as an existential threat.

I agree; I think there's a huge veil of perception thing happening here like. I've worked directly with dozens of coders and indirectly with hundreds, and like, no one does their job like I do? It's like we all show up to the job site, you have a drill, another person has a hammer, and I have a feather duster and a bottle of glue, and we all have the exact same job. No wonder what makes the drill person more productive doesn't do shit for the feather duster/glue person.

I've been thinking lately that the proliferation of ad-supported services, as well as venture capital supported services (free while they look for a way to monetize) is an overall bad thing.

If big companies are giving stuff away for free for 5 years, or a decade, or more, it's hard for any business to develop selling that stuff. It's hard to even justify the idea of selling that stuff, or similar stuff, when someone else is giving it away for free. It's unlikely that any charity will develop, giving these things away for free, because no one recognizes that is even charity. It prevents governments from recognizing that there are niches for fundamental services that have developed that could reasonably be provided by the government or by a regulated utility.

I don't know what to do about companies giving things away for free and people and even society becoming dependent on it. It doesn't seem like it's going to stop on it's own.

LAN is being used in an under specified way. To my reading, a separate VLAN or standalone LAN for the washing machine wouldn’t be on “my (main/primary LAN is assumed here) local network” if I mean that “my local network” doesn’t have untrusted devices on it. I tend to read these kinds of comments with a bit of wiggle room because sometimes folks disagree about if VLANs are actually isolated enough to consider them separate local networks, as the same device may do routing and firewall or VLAN tagging, so there is isolation in principle, but bad actors can’t be expected to comply with network security policies.

I guess I can see how each of you could be right to their own reading.

I love this! It would be great to have follow-ups and series of books about how to make things worse, as a way to learn to make things better.

Maybe it could be like O’Reilly, except the covers could have shittily-drawn fantasy animals, e.g. a 7-year-old’s drawing of a unicorn with a head on each side of its body both talking on their AirPods giving away their money to scammers, making PowerPoint slides, eating too much, doing hard drugs, live-streaming on Facebook, and standing on the railroad tracks with a train in the distance.

from https://www.outsideonline.com/health/training-performance/be...

The key ingredient in beet juice, from an endurance perspective, is nitrate. Once you eat it, bacteria in your mouth convert nitrate to nitrite. Then the acidity in your stomach helps convert the nitrite to nitric oxide. Nitric oxide plays a whole bunch of roles in the body. That includes cueing your blood vessels to dilate, or widen, delivering more oxygen to the muscles, faster.

The article summarizes the results of several studies into beetroot juice for physical athletic performance.

I sent the following summary to Andy Jones, the scientist most associated with beet juice research, to see whether he would agree: “It works. It probably works less well in elites, like most things, but there may still be an effect. Higher doses taken for at least a few days in a row probably increase your chances of a positive effect.” Jones thought that sounded reasonable. He pointed out that there’s a separate body of evidence emerging that beet juice also enhances muscle strength and power in some circumstances, an effect that Poon’s review confirms.

I'm building Journoo, an Ai-native journaling/diary app as an intelligent companion and memory repository for mental well-being, accountability, seeing patterns, critical thinking, processing thoughts/feelings, making better decisions, thinking of others, creativity, help staying focused on long-term aim/goals, and documenting and remembering your life - all according to your core values (via text, voice, and image).

Basically a productivity tool for making sense of reality and living your best life.

I love making something truly valuable and it's also a crash course on AI product/app development. Absolutely having the time of my life and am so grateful to be on this path!

>In practice, no one donates like this with their own money. They just vote for the government to take incremental money from others via ever more taxation.

In practice they throw piles of money at Trump - knowingly that it will lead to them saving an even larger money pile and thusly a net win.

Trump, who then happily drives up debt. Taxing people more is so uncool, so let's go easy on the whole taxes thing, just have the money printer go brrrrr and let inflationary tax serve its purpose

> Just a single YouTube video in a single firefox tab will bring you up to at least 10W.

10W for video playback is a lot. 5w average for light workloads is not unrealistic... I think your perception of power consumption is a number of years out of date at this point.

After all, Apple claims 18 hours from a 54watt-hour battery - you really think nobody else can get within 2x of that?

I at least appreciate that Bezos is now transparent with his transactional beliefs, instead of trying to wrap them in some bullshit moral superiority.

During Trump I, WaPo was all "Democracy Dies In Darkness". Trump II is all about "Hey, we don't do presidential endorsements anymore" and "our opinion pages are only about defending personal liberties and free markets".

> Consider "200". Is this the year 200? Is this the 200th day of the current year? Surprise, in ISO 8601 it’s neither — it’s a decade, spanning from the year 2000 to the year 2010. And "20" is the century from the year 2000 to the year 2100.

In any sane system, giving a function "200" as an input and asking what date/datetime it represents should return some sort of error.

Some inputs are too ambiguous to meaningfully parse.

Peculiar right?

A well funded agency would likely be able to develop a sensor package which tracks objects with multiple cameras with various zoom lenses and spectrums (IR/UV/etc.) and also radio.

I think tech is becoming so good eventually some enterprising UAP engineer is going to be able to cobble something together with off the shelf components and start selling kits.

Probably nothing will come of it still, I think, but who knows?

A Pomodoro timer to improve my skills but primarily as an excuse to get better at various AI coding tools when they pop up.

A website down-time detector because I think I can make money off it and learn a few things so I can later launch a grown-up SaaS.

A replacement for MS Notepad but with Markdown support. (I know Notepad sort of added this but it isn't great.) It's the tool I want to have when I say, "I like the way I can edit things in Notion and Obsidian but 95% of the functionality of those apps feel like bloat for my use case".

> Consider the discrepancies in jobs requiring similar education and responsibility, or similar skills, but divided by gender. The median earnings of information technology managers (mostly men) are 27 percent higher than human resources managers (mostly women), according to Bureau of Labor Statistics data.

Way to blow up their credibility in one sentence... Those are completely different jobs. An IT manager needs both management skills and sufficient technical knowledge to make decisions about technical matters and effectively supervise technical employees. Those skills are in higher demand, resulting in higher pay for IC staff and managers.

Also, numerous studies have found that the pay differences within job categories are largely accounted for by factors like overtime, lack of flexibility, stressful work environments, long commutes, etc. Society encourages men to pursue higher compensation, so it's hardly surprising that they are willing to put up with more for an extra 5-10%, even if it's to the detriment of their health and work-life balance.
Ask HN: How do you build B2B software that pays living expenses?
by architectofsw | 2025-07-27 22:50:26+00:00
I spent years at medium and large size companies. I have worked with product managers, designers, ux, cx, engineering teams etc. Two of my experiences were at early stage companies who got acquired.

While I do know some people are they are mostly employees.

How do you think and build b2b software that I can sell to earn living expenses? I think I need about $70k-$80k as a single (after divorce) person.

I would appreciate your help and thoughts on -

1. Finding ideas that are YC scale. Ideas that are good enough to be accepted by YC.

2. Where to find these people for reaching out? I know Apollo and LinkedIn is buzzing. Since most of my network is fellow employees I don’t know how to reach out to decision makers.

3. If there are such groups, where do I meet them? I am in far east side of. Washington without major tech activity.

I had a great extremely nasty divorce. Divorce has big impact on me but I am ready to build again and live my life.

I'm working on hessra.net, a token-based authorization system for machines and built using biscuits. The idea is that any service/machine/IoT device can authenticate to the service and get authorization tokens for each request based on policy. Then the tokens can be included with the request and verified without any further RTTs using the service's public key. The tokens are meant to be single-use and scoped to a single request.

Besides the simple "get token and send to a thing that uses it to authorize a request" there's a couple of things we've built/are building on top:

service-chains: for a given resource, you can configure the token so that it needs to be signed by notable components along the path of the request, and at each step along the path check that it was signed by expected components up to that point. the thinking is this could really cut down on lateral movement in a system

multi-party authorization: for a given resource, you can configure N authorization services that also need to sign the token based on their policy. the token only authorizes if all parties have signed it. this could be useful for managing capabilities of software deployed into customer environments or perhaps for b2b agents to get signoff from both b's for doing an action

I agree with this take, insofar as I interpret it as "we do a lot of bullshit that doesn't matter". Like, do you remember people arguing Rails vs Django, or even worse Rails vs Sinatra? I do and did, and my meager defense is that I was young and naive. The list of "I can't believe we spent any time building/doing any of that" is just so, so long. I mean, how many times are we gonna reimplement node ffs.

The cuts to NASA as well as NOAA, NIH, USGS, USDA, FWS, DOE, etc. are not really saving that much money, but are destroying literally trillions of dollars of future economic value (not to mention all sorts of work whose value can't be easily quantified).

Maybe "smashing things and ruining people's lives and work is fun per se" is a better explanation than anything more complicated. Pretty shitty for the rest of us though.

Our previous washing machine had a mechanical rotating switch, sort of like an egg timer, built into it. I seriously thought about just gluing a pair of metal bits onto it to make a physical connection when it was done, which would either do something clever like trigger a RasPi into sending me a text, or something stupid like physically triggering a doorbell chime.

A serious dent in the human population or something as severe as a world-wide nuclear war would look like a complete destabilization of existing supply chains and world economy. Sure, humans might exist on earth but nothing about the quality of that life is guaranteed - might be backed to subsistence agriculture at best and never recover since all the raw materials that are accessible that let us leave that kind of lifestyle have been thoroughly mined.

Basically, the current quality of life is never again attainable by any other species full stop because of those resources having been consumed to get to today. If the point of life is just to exist as animals then sure, no need to worry. If the point of life is to reach and strive to touch the stars and achieve a kind of immortality for our species, it feels like we’re in danger of permanently dooming planet Earth to never producing such a species.

the sans-IO approach seems roughly correct

libraries provide pure processing machines that pull data in through well defined input functions (and output through return), and then it's up to the callsite (or host code or however we want to call our code) to decide what kind of color to paint the whole thing eventually.

this helps testability and composability too.

It doesn't support what you wrote.

"The U.S. budget deficit exploded in fiscal year 2009, ultimately reaching $1.4 trillion under President George W. Bush...The deficit would remain above $1 trillion throughout the 2012 fiscal year, but it was slashed to as low as $440 billion in the later years of Obama's presidency."

Comparing Biden to GWB doesn't make any sense. Their presidencies were 12 years apart and in very different circumstances.

Looking at the number of already discovered vulnerabilities in popular applications, I would say it's actually impossible to build secure systems right now. Even companies that are trying are failing. IMO it's still way too easy to introduce a vulnerability and then miss it in both review and pentests. We need big changes in all parts of the software buliding and maintaining process. Probably no one will like that, because we are still in "move fast and break things" software development age.

Lately I’ve been heads‑down on a complete rethink of my dotfiles setup. It’s not just a `.vimrc` collection – the goal is to treat the dev environment like any other project: reproducible from scratch, automated, and designed to scale as AI becomes a bigger part of daily work.

The core of the project is a “Spilled Coffee Principle,” which basically says that if I spill coffee on my laptop, I should be back up in an afternoon. Every configuration change is codified into scripts, not a one‑off terminal command. Setup scripts create directories, handle symlinks, document dependencies and generally remove the “Brent the bottleneck hero” problem.

Beyond that, the repo lives inside a P.P.V system (Pillars, Pipelines, Vaults) where dotfiles are one of the pillars. This structure separates foundational configs from automation pipelines and secure vaults. It forces me to think at the system level: how do all of my tools fit together, where do secrets live, and how can I onboard a new machine (or person) with a single `git clone && ./setup.sh`?

What’s really interesting is the mindset shift this has caused. I’ve been experimenting with what I call the OSE (“Outside and Slightly Elevated”) principle: moving from micro‑level, line‑by‑line coding to a macro‑level role where you orchestrate AI agents. At the micro level you’re navigating files in an editor and debugging sequentially; at the macro level you’re using tmux + git worktrees + AI coding assistants to run multiple tasks in parallel. Instead of `1 developer × 1 task = linear productivity`, you get `1 developer × N tasks × parallel execution`, which has obvious 100×–1000× potential. This OSE approach forces me to design workflows, delegate implementation to agents, and focus on the “why” and “what” instead of the “how”.

The result is that my dotfiles aren’t just about aliases anymore; they’re a platform that bootstraps AI‑assisted development, enforces good practices, and keeps me thinking about the bigger picture rather than getting lost tweaking my prompt or editor colours. I’d love to hear how others are approaching the macro vs. micro balance in their own setups.

Two things:

I am building a Pinterest clone that filters out AI generated imagery[1]. It is built on top of Bluesky so gets the benefit of its large library of well alt-text'd images, which aids with search.

Also working on a new kind of social media, where every user is a verified human[2]. The idea is to avoid the problems that sock puppet accounts controlled by the rich and powerful can have on our society. Again, I am starting with Bluesky as a target demographic and have already had some adoption.

> Did you consider things like JScript.NET? jsc.exe still comes with every Windows installation, and JScript still runs on IIS server (I have built a few things with it).

I've not heard of any of these, wow – very cool that it's still bundled with Windows. I suspect that most things related to JScript wouldn't fit the scope of "the last decade", though? I tended to focus on creation date when deciding what should be in scope.

> And what about things like Adobe Photoshop, After Effects, Premiere, and Illustrator which can run Javascript using either Extendscript in older versions or V8 in modern versions.

Hmm, these may well qualify, you're right. Maybe I can add them to the addendum. I'd want to do a bit of research to understand their timeline and genealogy before including them, though. Wrists beginning to hurt for today now, though!

I do recall now that Adobe PDFs can run JavaScript. That would've been worth a mention for sure.

I don't know how common this is, but the fschat library maintainers went for at least a year without making an official release or updating the version number in their GitHub repo, so the only way to both have current code and a reproducible build (without just including the fschat library directly, of course) was to pin it to a particular GitHub commit hash, which would get you code that was current, but with the version number from 12+ months earlier.

fschat is pretty popular for LLM-related work, so I assume this is at least not unheard-of for other notable third-party libraries.
