Show HN: See the carbon impact of your cloud as you code
by hkh | 2025-12-16 15:22:42+00:00
Hey folks, I’m Hassan, one of the co-founders of Infracost (https://www.infracost.io). Infracost helps engineers see and reduce the cloud cost of each infrastructure change before they merge their code.

The way Infracost works is we gather pricing data from Amazon Web Services, Microsoft Azure and Google Cloud. What we call a ‘Pricing Service’, which now holds around 4 million live price points (!!). Then we map these prices to infrastructure code. Once the mapping is done, it enables us to show the cost impact of a code change before it is merged, directly in GitHub, GitLab etc. Kind of like a checkout-screen for cloud infrastructure.

We’ve been building since 2020 (we were part of YC W21 batch), and iterating on the product, building out a team etc. However, back in 2020 one of our users asked if we can also show the carbon impact alongside costs.

It has been itching my brain since then. The biggest challenge has always been the carbon data. The mapping of carbon data to infrastructure is time consuming, but it is possible since we’ve done it with cloud costs. But we need the raw carbon data first. The discussions that have happened in the last few years finally led me to a company called Greenpixie in the UK. A few of our existing customers were using them already, so I immediately connected with the founder, John.

Greenpixie said they have the data (AHA!!) And their data is verified (ISO-14064 & aligned with the Greenhouse Gas Protocol). As soon as I talked to a few of their customers, I asked my team to see if we can actually finally do this, and build it.

My thinking is this: some engineers will care, and some will not (or maybe some will love it and some will hate it!). For those who care, cost and carbon are actually linked; meaning if you reduce the carbon, you usually reduce the cost of the cloud too. It can act as another motivation factor.

And now, it is here, and I’d love your feedback. Try it out by going to https://dashboard.infracost.io/, create an account, set up with the GitHub app or GitLab app, and send a pull request with Terraform changes (you can use our example terraform file). It will then show you the cost impact alongside the carbon impact, and how you can optimize it.

I’d especially love to hear your feedback on if you think carbon is a big driver for engineers within your teams, or if carbon is a big driver for your company (i.e. is there anything top-down about carbon).

AMA - I’ll be monitoring the thread :)

Thanks all

In a world ruled by game theory alone marketing is pointless. Everyone already makes the most rational choice and has all the information, so why appeal to their emotions, build brand awareness or even tell them about your products. Yet companies spend a lot of money on marketing, and game theory tells us that they wouldn't do that without reason

Game theory makes a lot of simplifying assumptions. In the real world most decisions are made under constraints, and you typically lack a lot of information and can't dedicate enough resources to each question to find the optimal choice given the information you have. Game theory is incredibly useful, especially when talking about big, carefully thought out decisions, but it's far from a perfect description of reality

Kate is such a refreshing change. Super responsive and fast under Asahi. It's the best dev environment I've worked with in a very long time.

A few niggles with the switch, like it seems to assume Git but I'm using Fossil. I also haven't found a decent cheat-sheet for keyboard controls. I got duplicate block and move block working, and really enjoy the column editing, but still using cut for line delete.

I think KWrite is the same engine underneath? at least it feels much akin to Kate. I use it mainly for assembly files, since I was able to hack in an armv8 syntax file and needed a different theme than Kate.

I would argue in fact almost all fMRI research is unreliable, and formally so (test-retest reliabilities are in fact quite miserable: see my post below).

https://news.ycombinator.com/item?id=46289133

EDIT: The reason being, with reliabilities as bad as these, it is obvious almost all fMRI studies are massively underpowered, and you really need to have hundreds or even up to a thousand participants to detect effects with any statistical reliability. Very few fMRI studies ever have even close to these numbers (https://www.nature.com/articles/s42003-018-0073-z).

This article has a weird progression.

It starts with the origins of TNR. Then it basically says it's a decent font with no significant problems. Then it talks about how it's popular because it's the default.

Then in the last paragraph it takes a hard stance that you should not use TNR unless required. It even implores the reader with a bold "please stop". It makes no arguments to support this stance and offers no alternatives.

At federal minimum wage, you make 15k a year. NASDAQ 100 is on average 14.6% per year. It only takes 100k to passively earn more than the vast majority of labor.

We have arrived to the point where capital is vastly more important and productive than labor. AI has only make that worse. Historically, there has been a balance because it was Capital and labor that were required to generate outsized returns. But once you strip out incremental cost with software, and tack on an AI "service" layer, where are the need for employees?

The one saving grace, is that this will also break the VC model. When one youtuber who has 100k subs can spin out 20 different apps a year, we fragment the app space, allowing alot of micro businesses to form around "brands". But "brands" will just be social media influencers.

> Of course we could all sit quietly on a pillow in zazen pose, minds blank, freeing ourselves of want and desire, living happily and peacefully with nothing. But that sounds boring.

Nobody said you have to do this alone.

I'm an overspender, probably for mental health reasons or whatever. Still I know that what I'll remember on my death bed will not be my Apple Watch or my car.

I'll remember laughing with my son, with my wife, partying with friends, learning rollerblading, riding rollercoasters, I'll remember the good movies, the good videogames, the good music. I'll remember the theatre. I'll remember the people I loved.

That doesn't sound boring at all.

An acquaintance of mine bought a really beautiful car, a brand new Porsche 911. I actually like it but he doesnt want anyone to touch it and barely drives it himself because he is afraid of damaging it. To be able to buy this car, he sacrificed his familly life and saw his wife and daughter only on weekends for years. That, to me, sounds boring.

Fuck did it really? How on earth does that pan out? Who uses notepad? Writers? Word. Coders? Vim or VSCode or <IDE of choice>. I just don’t understand their logic.

They make this beautiful pasture (Windows XP wallpaper) and then lay mines all over the field. Put up signs that say “Free Lemonade” and charge for parking.

Hi, I’m a member of the Monadic DNA team.

This post describes a local-first approach to personal genomics. Large-scale analysis (processing raw genotype data against the GWAS Catalog, >1M traits) runs entirely on the user’s device.

LLMs are used only for exploration and summarization of selected results and they never see raw genetic data. Users can choose different LLM backends depending on their preferences, including a TEE-based option ( nilAI), local models via Ollama, or hosted models via HuggingFace.

Happy to answer technical questions about the pipeline, privacy tradeoffs, or limitations.

It can be seen though. Thats why I referred back to the Arc browser. People saw the real differences and it had fairly brisk adoption across a number of different type of folks, it didn't narrowly target technologists. Our designers, for example, at my last job, loved the heck out of it.

It was good enough for Atlassian to buy the whole company for a good chunk of cash too, if I recall correctly.

The abrupt ending of Arc's development has now left a hole in the market that Firefox could fill and gain marketshare.

If you think eastern philosophical traditions have resulted in comparatively less consumerist desire in Asia, you’re in for a disappointment. You don’t have to transcend to some spiritual enlightenment. I understood what the author was getting at very well, and it makes sense to me. When you have a mission in life, things that don’t serve your mission are worthless to you. When you don’t have a mission, it’s easy to get caught up in vain consumerism.

I think it's not quite as bad as you're making it out to be. If Apple's abuse of their position became truly intolerable GP is correct: people would stop buying their products. Apple knows this, and that limits how aggressive they can be with their anti-consumer nonsense and forces them to keep innovating.

So market forces do still work on Apple, just not as efficiently as they otherwise would in the absence of these artificial barriers to competition.

Software is somewhat unique in its ability to act against the interests of the person who owns it. Trying to design a fridge to not refrigerate your competitor's food would be impractical and probably easy for consumers to bypass. But designing an operating system which won't run your competitor's software? Trivial, and very hard to bypass. Because of this, companies that write software include anti-consumer features like that all the time to the point where it's almost expected now.

> If true (seems dubious to me), that's a ~20% difference. The difference in wages is a lot larger than that though, at least for tech workers. So that doesn't really explain why German tech can't compete against US tech.

https://www.oecd.org/en/data/indicators/hours-worked.html

1805 for the US (slightly more than the OECD average) vs. 1335 for Germany, which works the least.

Germany can't compete with US wages in tech because their companies don't generate as much revenue or profit, either per employee or in total.

> Also, there's quite a bit of evidence that a better work/life balance improves productivity.

There is, and the US is more productive per hour worked than the EU. Maybe that work/life balance in the US isn't as bad as reddit would have you believe.

> I think vacation time is a red herring. My guess is that the various forms of worker protection, making it impossible or very laborious+expensive to get rid of disfunctional team members, are a much larger factor.

An emphasis on regulation over productivity is the core issue IMO, including mandates for paid time off. By incentivizing leisure and bureaucracy designed to stifle change (both for the better and for the worse), you're effectively punishing highly productive individuals.

> But also, let's not forget that the major difference between the state of the economy in the US and the EU is Silicon Valley. Without its tech companies, the US doesn't amount to all that much anymore. This could also be explained as a historical fluke with lots of momentum.

No, productivity in the US is higher than the EU in nearly every sector: https://eei-institute.eu/publications/understanding-the-eu-u...

It's not a fluke. Like every other organization, the EU is getting what it encourages, which is stagnation and a lack of productivity. They will have to adapt at some point, the only question is how painful that process will be.

It's why the Unicode Collation Algorithm exists.

If you look in allkeys.txt (the base UCA data, used if you don't have language-specific stuff in your comparisons) for the two code points in question, you'll find:

004B ; [.2514.0020.0008] # LATIN CAPITAL LETTER K 212A ; [.2514.0020.0008] # KELVIN SIGN

The numbers in the brackets are values on level 1 (base), level 2 (typically used for accents), level 3 (typically used for case). So they are to compare identical under the UCA, in almost every case except for if you really need a tiebreaker.

Compare e.g. :

1D424 ; [.2514.0020.0005] # MATHEMATICAL BOLD SMALL K

which would compare equal to those under a case-insensitive accent-sensitive collation, but _not_a case-sensitive one (case-sensitive collations are always accent-sensitive, too).

> I hope that the association makes protectionism politically taboo for decades to come.

That is waaaay too black and white. Trump's actions != protectionism, Trump's actions ⊂ protectionism (and have been stupid). Free trade and globalization has failed most of the world in pretty serious ways (though it's been great for the much of the elite, floating on top of big piles of capital). Protectionism is important, it just needs to be conducted in a smarter way (instead of indiscriminately tariffing everyone all the sudden)

> I often tell my teammates exactly how I want them to implement something.

Ugh. I recently found myself working with one of those people. What a horrid experience. We waste days trying to reverse engineer out of him what the business problem actually is, and then, once we finally figure that out, even more going over all the things he failed to consider.

Software isn't the technical Olympics. It sole purpose in life is to solve human problems. You must work from understanding the human problems. "This is how we are going to do it" obscures all of the information that is necessary to write good software. I have no qualms about pushing back to ensure that we start from the right place, but it is so draining when it happens over and over. Building software doesn't have to be so stupid.

Don't be that guy.

> I ask myself all the time whether I'm insisting on too much control.

No. You're not. Someone has to wrangle those who are not providing positive contributions (without a forceful hand). But your job is to figure out why they are not providing positive contributions and solve for that problem, not to continually tell them how to do their job. You are no longer in a technical role. "Lead" means you are now in a people role, solving people problems not suitable to be solved with tech.

If you'd rather be a software developer, consider doing that job instead.

Some courts publish word processing templates for briefs; for example, the U.S. Court of Appeals for the Fourth Circuit: https://www.ca4.uscourts.gov/court-forms-fees/brief-template...

The Eighth Circuit gets really into this, publishing a typography guide for lawyers: https://federalcourt.press/wp-content/uploads/2018/03/Eighth...

Judges, particularly appellate judges, spend a lot of their time reading briefs. So, as you can see, some of them have strong opinions about brief typography. (Judges, as a group, have strong opinions about lots of things).

It's not so easy to setup. I mean: it's easy but it hits some real world constraints.

Example 1. I run Blockada on my Android phone, so I can block every ad even in apps and I can more or less firewall them (the outside calls). Blockada runs as a local VPN and unfortunately Android allows only one active VPN. So it's either Blockada or Wireguard. I'm with Blockada but I might occasionally want to disable it and enable Wireguard. I never did it yet because:

Example 2. WireGuard does not run everywhere. My little home ARM based server has a Linux kernel with some special driver to manage its hardware (it's pretty common on non-Raspberry ARM devices) and WireGuard does not run on it. It requires a newer kernel that I still cannot upgrade to and maybe I will never be able to. So I don't have anything to VPN to.

I might eventually put online a Raspberry, even an old model 3, as a bastion host on the home end of the VPN, but then it would be something else to care about and to power. It's not worth the mind share and the wattage so far.

I was mostly arguing that Altman's statements, if taken at face value, show him to be unfit to be a parent. I stand by this, but mostly because I think people like him -- Altman, Musk, I tend to conflate -- are robots masquerading as human beings.

That said, of course Altman is being cynical about this. He's just marketing his product, ChatGPT. I don't believe for a minute he really outsources his baby's well-being to an LLM.

As an attorney who specialized in IP practice in law school, I can tell you that your understanding of what a property right is is absolutely wrong. If you told a judge that copyright is not a property right, they’d stifle a laugh and advise you to come back with a lawyer, and your lawyer would, in turn, advise you to keep your legal opinions to yourself.

Both are rights to exclude enforced in law, which is the essence of what property law is. As the owner of physical property, you can exclude others from occupying or using it (with the violation being trespass). As the owner of intellectual property, you can exclude others from copying it, making derivative works, etc (with violations also enforceable in law).

Yes, both types of property rights are subject to limitations, either by law or by contract (as in the easement and mineral rights examples you gave). But that doesn't change the essence of what they are.

It's why the 3 branches of government worked so well for the US for so long. They each want to protect themselves, and are effectively at odds with each other unless there is almost universal agreement on something.

However that has completely fallen apart with a toothless Congress, and a executive branch that can stack the 3rd branch with similar minded idealogues.

Hey Community!

In The React Native Rewind #24: React Native 0.83 ships with <Activity>, useEffectEvent, and a desktop debugger that actually behaves. RNRepo cuts Android build times in half, Reanimated lands shared element transitions.

Also: Expo Targets tries to make native extensions less painful — not easy, but getting there.

If the Rewind helps you debug less or build faster — a share, reply, or confused emoji is always appreciated

My personal experience doing this for about 1.5 years is that if your personal project solves meaningful problems that you have personally there are great odds other people will find it equally useful provided it does something different or better than existing solutions. That is all that's required to make an open source hobby project at least marginally successful, but you are correct in that it will absolutely not gauge value of a potential commercial project.

Paying users are very different than casual users. This marketability is nonetheless predictable though. Projects that solve a business problem of greater expense than what they cost in monetary charges pay for themselves, which is more than sufficient to determine product-market fit provided salesmanship and merchandising.
Show HN: Veriduct Prime – Format destruction framework for binary evasion
by float_val | 2025-12-16 15:29:02+00:00
I built a framework that destroys binary file formats into chunks that evade detection, then executes them directly from memory without writing files.

Validation: Original binary gets 58/72 detections on VirusTotal. Format-destroyed chunks get 0/62. Reconstruct it, 58/72 again with byte-perfect hash match. It's deterministic.

It's not encryption (no file structure remains), not obfuscation (format is destroyed, not hidden), not packing (no stub loader needed).

Test battery: 75% success rate. Console apps, network tools, crypto, and threading work. GUI apps and DLLs don't (documented in KNOWN_LIMITATIONS.md).

Includes working C2 beacon executing from chunks.

MIT licensed. Full source on GitHub. Would love to find edge cases or binaries that break it.

That’s not true at all. We just don’t talk much about the ones we won.

> To put it in HN terms, this is what people here like to use to shit on Mozilla for how much they pay their executives while having zero insight into how much Firefox's for-profit competitors pay their executives.

It's dubious to say Google "competes" with Mozilla, because they pay Mozilla to develop Firefox to avoid antitrust issues, but it's easy enough to find CEO compensation for public companies.

https://www.sec.gov/answers/execcomp.htm

Of course people have published the numbers for well known companies:

https://www.jagranjosh.com/general-knowledge/highest-paid-ce...

Also, "Other companies pay their CEOs ridiculous amounts, so we're going to," is a poor justification, and just shows Mozilla execs are there to enrich themselves, and don't really care about the browser or community. But I guess they can't spend all of the money on Pocket and AI.
