I am working on the Vanta for sustainability and climate disclosures. Climate and sustainability disclosures are starting to come online in many sectors and parts of the world. We offer compliance-as-a-service so that startups and covered entities can fulfill their compliance requirements in a mostly self-serve manner without having to hire expensive consultants or undergo significant restructurings. Our platform provides a single source of truth for your climate, sustainability, and emissions data. For example, if you are an American company trying to go-to-market in Europe, all it takes is purchasing an additional module and we will automatically generate the compliance documents and checklists for you based on the existing data we have on your company. We also offer managed “Climate Trust Center” dashboards that you can subdomain on your website for investors reporting and to satisfy disclosure requirements.

If you are in an EPA-regulated (or equivalents in Canada and Europe) industry (such as mining, oil and gas, minerals, rare earths, metal processing, airlines, construction, shipping/marine, logistics, heavy industries, agriculture/farming/food production, data center, power generation including renewables, adjacent ones like consumer goods, real estate, large scale AI training, climate derivatives etc.) or require sustainability consulting support in general, we would love to talk to you:

Show HN: Trendly–A Personalized Feed to Cut Through Content Overload
Hi everyone! I’m excited to introduce Trendly (trendly.global), an app I think you’ll find really useful.

Here’s what we’re solving:
* Social media is full of fake news and lacks depth, yet many still rely on it for updates.
* There’s too much content online, making it hard to find what really interests you.
* Switching between platforms to get full details on a topic is tiring.

Trendly (https://trendly.global/) is a mobile app that curates a personalized feed with trending updates based on your interests. It lets you dive deeper by asking follow-up questions as a chat—all in one app.

We’re in the early stages, so while the chat function isn’t live yet, the other features are ready:
* The feed acts as a recommendation engine, curating content based on past interactions.
* Delivers concise, bullet-point summaries instead of lengthy articles
* Pre-generated Q&A for easy understanding

Check it out and share your honest feedback!
Everheard of copy/paste? Not unlike the way you copy/paste these css classes from the last project to the next.

Guess what? Taiwind has components too, but the built-in of course is never the exact thing people want, so they had to add utility classes. And when it doesn't cut, you go back to css anyway. A pointless effort only to add another thing you have to manage just for styling.
I agree. If all you need is Linux on a bog standard machine and would rather spend your time doing something else than tinkering on your OS, nix is not for you. Life is short and there are lots of things to do - we all have different priorities.
Show HN: Finstruments - Financial instrument library built with Python
finstruments is a Python library designed for modeling financial instruments. It comes with the core financial instruments, such as forwards and options, out of the box, as well as position, trade, and portfolio models. finstruments comes with the basic building blocks, making it easy to extend and build new instruments for any asset class. These building blocks also provide the functionality to serialize and deserialize to and from JSON, enabling the ability to store a serialized format in a document database. This library is ideal for quantitative researchers, traders, and developers who need a streamlined way to build and interact with financial instruments.
ChatGPT is, as usual, full of shit here.

Forth-83 is not an implementation but a standard, superseded by the ANSI standard in 01994, though sometimes people confuse it with F83, which is Laxen and Perry's public-domain implementation of the Forth-83 standard. It came out in 01984. It runs on CP/M and MS-DOS, but the MS-DOS version is limited to a single 64-kibibyte segment. It has no facilities to support embedding it in a program written in another language.

eForth, if by that you mean Bill Muench's eForth, is written in, mostly, Forth, on top of a small assembly-language core. It also has no facilities to support embedding it in a program written in another language.

GForth is pretty usable and can be embedded, as documented in https://gforth.org/manual/Integrating-Gforth.html (which is down at the moment but will probably be back up soon along with forth-standard.org.)

I don't know anything about SwiftForth and picoForth, but so far ChatGPT is 1 for 3, so I wouldn't bet much on those either.

The Meaning of Wisdom
The measure is in GW which normally makes sense for power plants because they're capable of running 24h a day. GWh per day is what batteries need to be measured in and comparing a generation technology to a storage technology is a little dubious in the first place but comparing the peak output capacity is meaningless.

At the very least, you need to be able to measure how much battery was discharged (in gwh) over a long term, to show it's ability to compete/compare/replace nuclear (or any other generation technology).

This seems like a very clearly, "we don't need nuclear because batteries" piece that's either not well informed or misleading. Even if the case can be made, this article doesn't make it.
Let's do both, since one fosters the other.
This article is out of date; lots of progress has been made since then. The NIH-sponsored Intervention Testing Program showed conclusively and multiple times that rapamycin is able to extend the lifespan of mice about 10%; and more recently the lifespan of macaques was also shown to be extended. It works by fooling your cells into thinking there's no nutrition available, by inhibiting the "MTOR" receptor. It's well known that "dietary restriction" extends lifespan in most life forms. The doses needed are lower than the usual FDA-approved use of rapa for preventing rejection of transplanted kidneys, and bio-hackers have not encountered lots of side effects. Probably the best hope for increasing health-span, which matters more than life span. Since it's in the public domain, there's not much hope for getting large studies done to prove efficacy, but the "Pearl" study recently showed a good safety profile. Also, the Dog Aging project is in progress, enroll to increase the lifespan of your dog (or not, it's double-blind).

See https://www.rapamycin.news/
I don't really expect that there are Trump voters who could be convinced to vote for Harris by the op-ed, but I do think there could be voters who may have been on the verge of reconsidering Trump who may hear something like this story (of Bezos stopping an endorsement) as something that makes them identify their moment of reconsideration as a mistake because they think Bezo's behavior should be perceived as supporting the concept that Democrats and other anti-Trump parties are the ones off-kilter.
My general experience with Arch is that the up-to-date-ness is a double-edged sword, and you some times hit new bugs or incompatabilities. If it happens in nix i can simply just revert - you can select which OS build version you want to boot at startup - and wait a few days.

And for my eGPU setup it also gives me a lot more confidence to tinker and reboot - the barrier for me to do so is a lot lower when I know i can simply boot an older build of my OS instead of having to whip out the arch installer USB and arch-chroot into my root drive to fix a bricked install that no longer boots.

"This software is deemed compliant with best practices when used on systems 100% offline on a network without connectivity to the internet. A customer's choice to use this software outside of our recommended best practices is at the customer's discretion and assumption of liability."

Obviously if you want secure an air gapped system is the recommended best practice.

Meta-analyses are a cool way to perform a garbage in, garbage out exercise.
Are those blunders or accents? From my point of view you spelled diarrhea incorrectly, unlike how our lord and savior Noah Webster taught us.

Maybe language is fine if it conveys the intended meaning.
Is this specific to react?
I think there are some number of people who are trying to decide what's "true" or "real" and while I don't think they'd have even noticed a WaPo editorial, I do think they might hear that Bezos prevented an endorsement and see it as indicative that the endorsement of Harris was somehow dishonest and tally it as a stone on Trump's side of the "reality scale."
Got to the point the EICAR string was described as "very, very random" and became abruptly disinterested fwiw.

It's not random. It's a DOS .COM file encoded as printable 8-bit-clean ASCII. The whole point is that it's executable code.

I stopped watching from there so it's possible this was mentioned later in the video.
It's intentionally misleading. I have never understood what this is supposed to accomplish, since it's greenwashing at it's worst and will damage the battery storage (much less solar power in general) cause far more than it helps in the long term. It's utterly rampant in the renewable power space.

Eventually you run out of other people's power generation and these little wordplay tricks no longer work.

Follow the money, I suppose.

You have a very blinkered rosy eyed picture of the colonial settlement of the USofA.

The colonies were very much European sponsored investment enterprises with owners and stockholders with European values in addition to being opposed to Crown taxes raised by batshit loons with Royal blood (an issue in Europe and not just the US).

Post independance trade continued and the original colonies remained Anglophile (the English colonies at least, the Dutch and other colonies also retained European ties).

> In my experience this is not actually the case; I can usually remember a few parts of the character but draw a blank on the rest. You can see the picture of the grocery list that for some characters he got basically half the character right but gave up on the other half (shrimp is the combination of 虫 and 下, you can see he remembered the first half).

That one's just bizarre, since 虾 is also just the most intuitively obvious choice to form a substitute character if you do forget the right component. If anything, I don't think pinyin substitution is something you do unless you're a highly-educated computer user who deals regularly in Latin script. It's a striking "man bites dog" moment, but the one has been passed around since 2006 (cf. https://pinyin.info/readings/defrancis/chinese_writing_refor...) and is not, as far as I can tell, indicative of any particular trend.

> In practice, most people would find the result to be an incomprehensible mess.

Unless Chinese is somehow unique among all human languages, this isn't true. Chinese would be just as intelligible if written in a phonetic script (like Pinyin) as it is when written using the characters.

Now, it would be an incredibly shocking transition for Chinese people who have already spent their entire lives writing with characters. However, after the transition to Pinyin, especially for young people who wouldn't ever learn the characters, written Chinese would still be perfectly understandable.

That being said, I don't favor replacing the characters, because the transition would be extremely difficult and because the characters are very culturally important to China. They've been in use for a good 3000 years, and people are very attached to them. Phonetic scripts are technically superior, but the cultural and practical arguments for sticking with the characters are still stronger.

I'm a huge proponent of using SQLite as an abstraction over a filesystem. One warning I will note though, is be aware that a SQLite database does not shrink unless you vacuum it (basically copies the data into a separate file and deletes the original). This is a manual operation you have to do at points where it makes sense within your application. So be careful with disk usage when just writing binary data and then deleting it.
Nice idea, but right now the villagers mostly say some variation on "I eagerly await the valiant hero's return!". Beside the fact that no villagers would ever speak so formally, this seems to fall into the standard fantasy problem that the normal people in the world only exist to further the hero's agency. Could you give the villagers a sense of their own agency, meaning that they have lives of their own that would continue whether the hero returns or not?
My personal take on Bulma is that it is like an uglier version of Bootstrap CSS that doesn't work as well and is harder to modify (in my experience, from when I had to poke at it to fix some issues I was having).

I worked with it for a couple projects, I was not particularly pleased with it overall. It's okay, I guess, but just nothing to really write home about.

I'm working on a wearable device with a camera+ultrasonic sensor which is capable of accurate hand pose estimation, which will then result in sign language recognition mainly (extending to gesture recognition and HCI applications). The device should be able to integrate into a smartwatch. I'm only at the 'will it work?' stage, working on the algorithms for recognising ASL words through synthetic data. Would appreciate criticism and pointers on what to keep in mind :)

I'm building Reasonote, a platform where you can learn anything with personalized, interactive lessons, and podcasts.

Imagine a fusion of Duolingo, Spotify Podcasts, Anki, ChatGPT, and Claude Artifacts.

We have custom AI-generated podcasts that generate faster than NotebookLM, that you can queue up for yourself. (Many more features coming here soon -- like more engaging podcasts and better voices)

Our classroom mode can generate interactive lessons, complete with an AI tutor, on any subject.

Flow mode allows you to practice deeply, with infinite activities to test your skills.

All of this is driven by a dynamically generated and continuously updating "Skill Tree", which keeps track of the domain you're studying, and your progress within it.

I wouldn’t count on it.

Most people travel during vacations and typically choose air travel over spending extra vacation days on a train. Likewise, bullet trains don’t make much economic sense across national borders, as few people commute daily between countries for work (in the European Union).

The only way to make train travel economical is by artificially increasing costs of air travel or the costs of owning a car. This has slowly been happening already, but will likely lead to a larger divide within the EU.

Yes, but we don't need a train to replace NY-to-LA. At least not right away.

What we need are high speed trains between nearby city pairs. Short-haul flights both waste fuel, don't get up to speed, and have their travel times doubled by TSA security theater and airline boarding nonsense. A Shinkansen-spec high speed train (320kph/200mph) would beat the plane on 200-400 mile trips, both in terms of convenience, carbon emissions, and luxury.

The 2,785 road miles between NY and LA would be 14 rail hours compared to the six a plane takes. Not competitive in the slightest, and not a serious mode of travel, but I'd consider it. The three days the train currently takes sounds like the worst of a road trip combined with the worst of a plane trip.
Oh, when was this added? I'll have to check it out.
Several things:

1. Working on a 'production ready' version of Conal Elliot's 'compiling to categories' for GHC.

2. This is so I can create a vectorizable model of a datalog-based query language I'm building in Haskell.

3. The query engine will be using a version of monadic optimization as outlined on a blog post somewhere

4. The purpose of the query engine is maintenance of large datasets, all the more important with AI these days, but really general purpose.

5. The motivation for this was a low code tool I had built in Haskell almost a decade ago that I abandoned that I'm bringing up to use ghcs web assembly backend and I need a proper query engine for it now.

Other things:

1. Thinking about binary neural networks and how to train them stochastically.

2. Learning about finite element methods for physical modeling and also reviewing my basic topology so I can think more about non discrete math and algebra which I tend to focus on.

3. I'm building a cloud chamber! Because I want to see space particles. Literally for no other reason than I'm obsessed with these devices ever since seeing one at the exploratorium

4. And raising three kids. I don't know how I have time for anything

Pretty solid take on a roiling shitstorm that's been brewing for at least the last 15 years. One thing I strongly disagree with the author about is wanting the web to win. Of all possible outcomes the web coming out on top of the platform wars is the worst available. Simple fact of the matter is the web wasn't built for any of this shit as our bloated and still wildly insecure browsers demonstrate rather vividly. The web defaulting back to a largely static information display medium would free up so much client budget and development hours it's hard to imagine that multi-OS support for native apps wouldn't be a net savings over the long haul. Hell, just imagine the kinds of resources that would free up if forced migration of highly dynamic websites was a thing of the past (yeah I'm looking at you Drupal).
