There is a reason why almost all ERP apps end up being almost the same. When you build a product with a USP that makes you special, at some point your client will ask for all the basic things that are required for that product (provided by your competitors) and generally for businesses this becomes the reason to stay with you; your USP and you providing everything else that is expected from the product category.

The point is, you have defined your USP. Its cheaper Typeform alternative for SMBs, stick with it and build the product around it and meet all the basic requirements first. Do some research and find out which features a typical form builder wants or which Typeform features are most used. Have those ready and then work on the other fancy things.

And have a number in mind, after X number of clients increase your price. And seriously increase your price now.

Isn't the windtunnel test completely different from actual conditions? Mach 7 at 1 bar is wildy different than Mach 7 at very low pressure, isn't it?

My gut feeling tells me the paper plane doesn't have enough mass to "power through" the thickening atmosphere with enough force to substantially heat up.

Also, if it starts tumbling or not is not very relevant, it's still flying. Surely it could recover at some point, maybe at low altitude with higher air pressure and random turbulences.

You don't think the left had all these things in their favor? You think the media are all far right wing conservatives? People like Rachel Maddow and Oprah, you might consider to be much more right wing than even Dick Cheney? You don't think maybe there might be some issues out there that people voted on and maybe saying "I'm a middle class kld" and "I'm speaking" on a loop just didn't do it for them? No, it must be Murdoch, because Soros is a relative pauper by comparison. Really?

There is a pervasive feeling in our complex postindustrial society that one thing we are lacking is a little fucking slack, the sort of thing that might be unavoidably extended on a very regular basis in the primeval human tribe/clan. We get it where we can.

Turning employment and education into an up-or-out pressure cooker that thinks nothing of, for example, firing the bottom performing 10% of people every year, or failing a student who's fifteen minutes late to a final exam, is not what we are built, cognitively/socially/culturally, to tolerate. These people are taking a norm that we DO make a formal attempt to force tolerance on, disability, and trying to extend it to get the system to treat them more like a human being and less like a competitor.

Let's take a more consensus trend: ADHD.

ADHD barely existed as a recognized social phenomenon until the 1990's.

> I didn’t realize how much of a psychiatrist’s time was spent gatekeeping Adderall.

> The human brain wasn’t built for accounting or software engineering. A few lucky people can do these things ten hours a day, every day, with a smile. The rest of us start fidgeting and checking our cell phone somewhere around the thirty minute mark. I work near the financial district of a big city, so every day a new Senior Regional Manipulator Of Tiny Numbers comes in and tells me that his brain must be broken because he can’t sit still and manipulate tiny numbers as much as he wants. How come this is so hard for him, when all of his colleagues can work so diligently?

> (it’s because his colleagues are all on Adderall already – but telling him that will just make things worse)

> He goes on to give me his story about how he’s at risk of getting fired from his Senior Regional Manipulator Of Tiny Numbers position, and at this rate he’s never going to get the promotion to Vice President Of Staring At Giant Spreadsheets, so do I think I can give him some Adderall to help him through?

> Psychiatric guidelines are very clear on this point: only give Adderall to people who “genuinely” “have” “ADHD”.

Form builders are a hard business to succeed with. Quite a lot of companies started off as a general “form builder” product and then found success by specializing into specific uses of forms. Examples include Qualtrics, Survey Monkey, Open Water, etc. Quite a lot of other companies stick with generic forms and get stuck and stagnate.

The reason is that forms are like dates, time, addresses, names, to-do lists, etc. They are things that many developers need to work with, but are way deeper and more complicated than they seem at first. See the wide variety of feedback and suggestions just in this HN thread.

So I would recommend specializing if you want to gain traction. And expect to do tons of marketing.

I certainly stop to explore some topics where I may not have in the past, but that does lead to better code sometimes too.

>“When we watched the videos, we found that the AIs made some suggestions about their work, and the suggestions were often directionally correct, but not exactly what's needed,”

Being aware of this and investigating just sounds like responsible use of AI.

Upvotes are a lagging indicator. Despite all the leaderboard scores presented, etc, no one actually knows how good a model is until they go use it for a while. When Claude 4 got ~2k upvotes, it was because everyone realized that Claude 3.7 was such a good model in practice - it had little to do with the actual performance of 4.

The article notes several examples of reduced use of fossil fuels:

> California is so far using forty per cent less natural gas to generate electricity than it did in 2023

> total carbon emissions in China had actually decreased

> kept the country’s coal use flat and also cut the amount of natural gas used during the same period in 2024 by a quarter

I gave it a serious try for a side project. Entirely vibed from system design to backend, db, frontend and all sort of ci/cd hacks.

I ended up binning the fully vibed version and started again with a design of my own. This mostly because the final product wasn’t really usable.

Then I heavily modified the backend.

In the last days I finished a major refactoring of the frontend.

I’m now in the situation where the project is 20% vibe coded.

If I were to start again it would possibly be less than that. Just because in the process I learnt as much react I need to do things myself.

This was using a mix of gpt4, claude, gemini, lovable…basically anything with a free tier to squeeze free tokens from

> GPL 2.0 and GPL 3.0 (to a much more significant extent) disallow use of plugins. Or well, the do allow plugins, but at the cost of infecting the entirety of your own codebase with GPL 3.0 obligations.

> And that's my principle objection to GPL. Linking to GPL code infects my code, requiring me to also license my code via a GPL license.

No. You release a host application with no dependence on GPL code.

The end user loads a plugin that is (or uses) GPL code. The end user doesn't distribute anything.

In very practical terms, what is the enforcement here? Who is gonna sue the end user?

It does really vary based on the data set.

If the email data is mostly text with markup (like HTML/XML), you might want to try bzip3 too.

It's also possible that a large part of your email is actually already-compressed binary data (like PDFs and images) possibly encoded in base-64. In that case it's likely that all tools are pretty good at compressing the text and headers, but can do little to compress the attachments, which would explain why the results you get are so close.

He is a pretty important guy who does a lot of stuff all of the time that causes ripples throughout the entire world! I don’t read much about him beyond the headlines since I feel the same way about everything he does, but I understand why it fills up so much space.

Tbf it was different during his first term when every word he uttered made front-page news but rarely set off an actual major chain of events. That’s when I learned to tune out.

Someone had to actually write all that code and it inevitably shows up in the stats. People who work on the code most tend to know it the most. Although people in non-coding roles sometimes prefer to deny it.

Sure there had so be some frequent but low impact committers. But implying that people with lowest amount of code contribution must have more impact is ridiculous.

I mean, a staff engineer who stopped committing couple years ago? Yeah could be burnout, or could be some major contribution that's not in the stats. OTOH an IC on their second year in position who hadn't pushed a single line? Nah the institutional knowledge is safe without.

Can anyone point me a genuinely unbiased comparison of solar, wind, coal, oil, nuclear and hydro, in a reputable scientific journal that covers all of the 'criticisms' that are raised for some but not others?

There's at least:

- creation of infrastructure

- maintenance of infrastructure

- mining/acquiring fuel

- waste fuel

- retirement of infrastructure

and then for each point:

- something like cost per MWh,

- human deaths,

- animal deaths,

- CO2 emissions

- land area usage (or land area damage)

- others???

Yes. Each garage is different. If you are working on your car in an open garage that is an invite for someone else interested in cars to say hi, offer advice - and possibly pitch in when you are working on something that needs more than 1 person. If you see someone playing guitar in their garage that is an invite to bring your fiddle and join in. If you see someone playing pool that is your invite to play the next game. And so on. Note that there is nothing in the above list that will appeal to everyone, so if you don't like cars you walk by that garage, if you don't play music you walk by the guitar...

I think that's also not fully true. The trope is that the rich nobles were swimming in money and in their boredom they just tinkered and did hobby stuff and then this resulted in the discoveries.

But for example Galileo from Wikipedia:

> Three of Galileo's five siblings survived infancy. The youngest, Michelangelo (or Michelagnolo), also became a lutenist and composer who added to Galileo's financial burdens for the rest of his life.[22] Michelangelo was unable to contribute his fair share of their father's promised dowries to their brothers-in-law, who later attempted to seek legal remedies for payments due. Michelangelo also occasionally had to borrow funds from Galileo to support his musical endeavours and excursions. These financial burdens may have contributed to Galileo's early desire to develop inventions that would bring him additional income.[23]

Or Kepler:

> His grandfather, Sebald Kepler, had been Lord Mayor of the city. By the time Johannes was born, the Kepler family fortune was in decline. His father, Heinrich Kepler, earned a precarious living as a mercenary, and he left the family when Johannes was five years old. He was believed to have died in the Eighty Years' War in the Netherlands. His mother, Katharina Guldenmann, an innkeeper's daughter, was a healer and herbalist.

I think the pattern is less that they were so free from concern that they started to research, and more that they worked hard to get funded. And often incidental jobs, like calculating easter and astrology stuff (Kepler in Prague) and to the science as a bonus. Similar to how artists were mostly commissioned (like Leonardo) but also did their own "passion projects".

The typical intellectual was not some duke or baron or huge lord or the son of such. They had to be somewhat stable of course, but that's also true today. Today's professors also don't typically come from abject poverty.

Impartial benchmarks are great, unless (1) you have so many to choose from that you can game them (which is still true even if the benchmark makers themselves are absolutely beyond reproach), or (2) there's a difference between what you're testing and what you care about.

Goodhart's Law means 2 is approximately always true.

As it happens, we also have a lot of AI benchmarks to choose from.

Unfortunately this means every model basically has a vibe score right now, as the real independent tests are rapidly saturated into the "ooh shiny" region of the graph. Even the people working on e.g. the ARC-AGI benchmark don't think their own test is the last word.

I recently discovered that `perf` itself can spit out flamegraphs. My workflow has been:

$ perf record -g -F 99 ./my-program $ perf script report flamegraph

You can also run `perf script -F +pid > out.perf` and then open `out.perf` in Firefox's built-in profile viewer (which is super neat) https://profiler.firefox.com

My grandma is in hospice right now. Her son (my uncle) and myself continually visit and are involved in decisions surrounding her care. My uncle is being willed her estate. My uncle has no children. I have no children. At some point relatively soon there is going to be a lot of assets locked up with a geriatric population with no heirs.

Do you know that feeling when you waste tons of time searching for old documents, projects, or customer data across different systems? It’s driving me crazy. That’s why we’re building aigentwork – a platform where you can simply chat with your own data to get answers or generate content.

For example: “Show me all projects for client X from last year.” → aigentwork finds it for you.

Would you use something like this? Or what would be important for you if you were to use it?

If it sounds interesting, we’ve set up a waitlist here: https://aigentwork.com/

«Manual Folder Sorting» — first, they broke 3rd party plugin for that. Next, author (not member of official Thunderbird team or employee of Mozilla) of this plugin spent more than 1 year pushing this functionality into base.

Now they highlight it as big deal in new release without mention volunteer author of this BASIC feature which should be in mail client FROM VERSION 0.0.1!

It is pity, that Google Mail is «good enough» and it killed development of good desktop e-mail clients.

Thunderbird is best what we have (Cross-platform), but still very bad, and after killing off XUL plugins cannot be easily modified.

They exists for 21 year and now announce manual folder sorting! There is no support for Sieve (3rd party plugin? Dead after removing XUL)! There is no way to store folder settings as IMAP properties, and if I have two installations (on laptop and desktop, for example) I need repeat same setting or folders again and again — including selection of identity per-folder (again, not native functionality but 3rd party plugin, thanks, it is alive now!). No true message templates (per-folder, per-action, per-identity), only lousy "signature", broken in-line quoting in plain text messages, etc, etc, etc.

And it is best what I can use cross-platform :-(

21 years of progress and now we are here.

They could still have trained the model in such a way as to focus on benchmarks, e.g. training on more examples of ARC style questions.

What I've noticed when testing previous versions of Grok, on paper they were better at benchmarks, but when I used it the responses were always worse than Sonnet and Gemini even though Grok had higher benchmark scores.

Occasionally I test Grok to see if it could become my daily driver but it's never produced better answers than Claude or Gemini for me, regardless of what their marketing shows.

For grad students, yes, the money largely comes from grants (more than 50% of my funding in grad school was from grants from my advisor). The university doesn't actually take a chunk of the grant, they get an additional "overhead". This used to be 60%, now with the Trump administration its been cut to between 15% and 30% depending on the federal agency. For example, if the overhead was 30% and I get a $1000 grant from the NSF, the university will get an additional $300, but I still get the full $1000 (actually the university has full control of the $1000, but I can ask them nicely to use it).

I am more concerned with the research institution's effect on undergrads rather then grad students. Grad students have their own unique ways of being exploited.

If he didn't like those people, why would he want to share the country with millions of them?

Confederates weren't importing slaves (Let's just say there's a reason why slave auctions were often closed on Saturdays), but anyway, it's a different analogy since the slaves were not participating in society. They were slaves. They imported them knowing their kids will not share schools, they will not share restaurants, etc. They were imported with the impression they will not become American citizens. The millions of Indian workers have a pathway to greencard, or often they have children which become US citizens.

If you want to claim that Elon is racist despite him wanting millions of foreigners, you have to provide strong support for your claim.

If that's how you see it, literally everything costs money at some point in the line. So I guess nothing is free. But we have a word for it, so let's give it an actual use.

You enter at no cost (with exceptions, of course). That's free. They should continue to be open and free; a world without parks, without use of public funds for public good, isn't a good one. Profits be damned, I want my parks.

I built an app for iOS and android recently with a combination of Claude, and cursor. I started off by drawing Claude a picture of what I wanted the app to look like, and telling it to give me the skeleton of an iOS app. (It did a surprisingly good job)

Then I switched to cursor and iterated with it on making it work. Once I had the iOS app running, I got cursor to create an android app that looked and functioned the same.

Super interesting experience - took a couple of days of iterating here and there, helped to have them in git repos for when cursor went too far off piste.

Both apps work, they look pretty much like my original picture.. and the code is absolute trash. I don’t know swift, or particularly kotlin, but the code is horrendous. If you wanted to take them any further, you’d rewrite it from scratch.

This was. Rating combinations of Claude 3.7, 4.0 thinking, Gemini 2.5, and chatgpt 4. (Switching between agents when one was getting stuck.)

Observationally, they all had a much harder time with android and rarely produced anything that didn’t need fixing to build.

Great for rapid prototyping in a stack I don’t know, but 100% tech debt.

I’ve been working on a lightweight, header-only ECS called kawa::ecs that’s designed to be blazingly fast, minimal, and easy to use with modern C++20 features. If you’re building games, simulations, or AI systems and want a simple yet powerful ECS backbone, this might be worth checking out!

Quick example:

#include "registry.h" #include <string>

using namespace kawa::ecs;

struct Position { float x, y; }; struct Velocity { float x, y; }; struct Name { std::string name; };

int main() { registry reg(512);

entity_id e = reg.entity(); reg.emplace<Position>(e, 0.f, 0.f); reg.emplace<Velocity>(e, 1.f, 2.f); reg.emplace<Name>(e, "Bar"); // Simple query reg.query ( [](Position& p, Name* n) { std::cout << (n ? n->name : "unnamed") << " is at " << p.x << " " << p.y; } ); float delta_time = 0.16; // Parallel query (multi-threaded) reg.query_par ( [](float dt, Position& p, Velocity& v) { p.x += v.x * dt; p.y += v.y * dt; } , delta_time ); }

would they be doing that if they didn't have a guarantee that importation of millions of people will continue?

there are millions of Chinese and Indians who can buy those homes with cash.

That's for the whole country. This site is very heavily biased toward people who live in major cities, where real estate has in fact become the purview of only the rich.

Short version of the history:

Starting in the late 1990s, you had a super-concentration of both good jobs and interesting culture in a short list of cities: SF Bay, New York, LA/OC, Seattle, and a few others. I remember growing up during this period and the whole cultural zeitgeist was "if you don't live in one of those cities, you can't do anything."

These cities have always had an allure, especially creative centers like LA and NYC, but what I mean is that it got much more extreme. It fits with the general cultural zeitgeist of everything centralizing and going to the extreme right side in an increasingly tight power-law distribution.

This was followed by insane real estate hyperinflation in those cities, of course, because if you try to take all the "interesting" stuff in the world's largest economy and a nation of 300+ million people and cram it into a few metros, that happens.

The rest of the country still has a lot of affordable real estate, less so than it used to -- RE has appreciated everywhere and not just in the US -- but it's far less insane than the top-tier cities.

I post this every chance I get:

So, you really think there are no issues that anyone voted on? It's just that the left has no money and no audience? People like Soros and Oprah are just so unbelievably poor that they are no match? Basically, if it were not for Joe Rogan, who has a large audience but hardly captures half of the country, and other comedians, people would have been sublimely enamored with the intellectual tour de force that is "I'm a middle class kid" and "Today is the day that we will do what we do every day?" Basically, this view is that if it wasn't for podcasts and perhaps "foreign intelligence operations" people would have right realized that they agree with a litany or far left extremist positions. I guess that must be the only answer ::shrug::.

I feel like the news article doesn't emphasize that you aren't "launching" the plane any more than you would by setting it on the roof. So it's really surprising that it all happens in <4 days.

I thought atmospheric effects were much lower at that altitude, but apparently even the ISS loses about 3km every month (enough to deorbit in ~15 months).[1]

The ballistic coefficient of the ISS is a whopping >500 times greater than the plane so the plane drops really fast.
