This is perfect timing for me - was just thinking about how to do this. But pricing is a bit steep for a startup currently looking to prove the market. Would you consider a cheaper option (e.g. 1 free inbox, or maybe $20/mo for 5 agent inboxes and a more limited storage level)? I'm building something that I might consider this for, but I don't know how long my runway is before I get sustainable client revenue, so $100/month is a deep hole being burned in my personal pocket before I can prove my MVP out.

As somebody who has done both- mcp-use makes it very very simple.

If you are at all familiar w/ python back-end development, it's literally just as easy use this tool to make an API as it is to put your MCP into claude desktop.

MCP SDK is not hard to do per se... but it's more than a 5 minute job

Meh it's a little bit worse, because smaller reactors burn a smaller fraction of their fuel and therefore make more volume of high level waste per kWh generated.

But it's not THAT much worse. Nuclear waste is already ridiculously small in volume per kWh vs. any other fuel-burning energy technology. Right now all of the waste we've accumulated from making 20% of the country's electricity for decades fits on a football field 3 meters high (that's pellets only, if you include individual dry casks it's 135 meters). So if we make lots of small reactors that are a bit less fuel efficient we might need 2 big football fields deep underground rather than 1. Compared to all the particulate and CO₂ emissions other sources make I'm just not that worried about it. Recall that fossil kills ~6 million per year from particulate emissions alone. Commercial nuclear waste has never hurt anyone, and is unlikely to do so in the future.

It's funny because the biggest impact in my eyes is social and not technical: the standard library is controlled by project governance whereas libraries are not.

Zig moves fast with it's BFDL structure, Rust moves slow with its committees, and both are by design. I'm excited to watch the Zig standard library evolve quickly, especially once the language has settled things like I/O.
Show HN: FakeFind is working again – AI tool to detect fake reviews
by FakeFind_ai | 2025-07-31 21:19:55+00:00
Hi HN,

Just a quick update — FakeFind is back online.

We originally built FakeFind to help people spot fake reviews after Fakespot shut down. It scans product reviews on Amazon, Walmart, eBay, and others using AI to detect patterns like repetition, review hijacking, and mass posting. You get a Trust Score, an Adjusted Rating, and a short review summary so you know what’s real before you buy.

It’s browser-based, free to use, and doesn’t require installing anything.

If you tried it during our downtime — thanks for your patience. We’d love feedback from the HN community as we keep improving. For those who are interested: https://fakefind.ai

In chess, previous moves are irrelevant, and LLM aren't good with filtering out irrelevant data [1]. For better performance, you should include only the relevant data in the context window: the current state of then board.

The main difficulty is that most people do not like running a business, especially a small business. For most of these businesses, you are buying yourself a job. Let's say you take out $1.5MM loan to open a shop, and you net $70,000 per year on a good year after expenses and debt service. After a few years, you have $1MM left to pay and there's no way you could sell the business for that. You have a personal guarantee on the loan.

Your vendors are always coming up with new ways to tack on extra charges. You have to deal with training, HR, bookkeeping, payroll, handyman tasks, cleaning, working shifts when your employees flake out, annoying customers, dangerous people, destructive customers, employee drama, the list goes on. If that is not what you enjoy, you will have a lot of your life doing things you do not enjoy. Sipping tasty coffee and chatting with your happy customers is a small part of the whole.

"Nature also analyzed its jobs board and found “that US scientists submitted 32% more applications for jobs abroad between January and March 2025 than during the same period in 2024.”

"Scientists who have felt abandoned in the U.S. are being courted by institutions across the world. Aix-Marseille University (AMU), located in France, "introduced eight U.S.-based researchers who were in the final stage of joining the institution's 'Safe Place for Science' program, which aims to woo researchers who have experienced or fear funding cuts under the Trump administration," said Politico. The program has received close to 300 applications from some of the top institutions in the U.S."

Source: https://theweek.com/science/scientists-refugees-research-tru...

"There are also new scientific refugees in the making. Trump's "big, beautiful bill" calls for a 56% cut to the National Science Foundation budget and a 73% reduction in staff and fellowships. It also cuts resources from the National Oceanic and Atmospheric Administration, Environmental Protection Agency, Department of Agriculture and U.S. Geological Service. There is a "whole generation of young scientists who see no pathway into the field for them,""

> Why is housing always about the homeless?

To me, poverty is basically the only thing worth talking about when it comes to politics. Nothing else is going to get me to the voting box—to me, a platform that doesn't focus on poverty reduction doesn't even understand the point of government, the economy, or trying to work together.

I suspect other folks who think this way are going to be disproportionately loud.

IIRC it is the efficiency of the chemical process in the battery that is affected by cold temperatures. Different chemistries are affected differently.

This is a part of the reason why EVs will actually spend energy to warm up their battery packs in the cold, spending the energy to warm it up early will lead to better efficiency for the rest of the drive. Another reason why it's better to condition the car plugged in before starting a trip in the cold; the battery is already in its optimal temperature range.

This is great but as usual, the specifics on 'how to execute' are highly culture-dependent. Some of the ways he proposes to talk to decision makers would cause them to be seen as unserious or disingenuous where I'm from.

For example, hitting senior people with 3-4 questions via Chat or, godforbid, sending them a Word Document with questions would not get you taken very seriously here.

Subtlety is key. Less is more.

You certainly could create an embedding of your code and then hooking it up to OpenWeb UI or equivalent as a chat interface - we've actually spoked to some teams that have rolled their own custom solution like that!

From a product POV: our main focus with Sourcebot is providing a world-class DX and UX so that it is really easy to use. Practically speaking, for DX: a sys-admin should be able to throw Sourcebot up into their cluster in minutes with minimal maintenance overhead. For UX: provide a snappy interface that is minimal and gets out of your way.

From a technology POV: vector embeddings (and techniques like graph-RAG) are definitely something we are going to investigate as a means of improving the agent's ability to find relevant context fast. Bringing in additional context sources (like git history, logs, GitHub issues, etc.) is also something we plan to investigate. It's a really fascinating problem :)

If you ship in a stack of panels, inverters and cables, sure. But maybe you could be a little smarter about it, like a container with all the electronics (inverters, batteries, management) and a bunch of folded, pre-cabled panels that you can pull out across a field. If you bring a couple of those covering a field in a few hours shouldn't be that hard and could be ready for use instantly provided the batteries are charged at delivery.

It’s a supply-side problem, but with majority of people being either indifferent to the problem or against downward pressure on the housing prices (most people don’t rent). The prices have skyrocketed, and most people who bought in the last 5 years wouldn’t want their assets to depreciate, if they spent 500K+ on it.

How it works:

Websocket:

1. Two AWS ec2 t4g.nano instances polling the SEC's RSS and EFTS endpoints. (RSS is faster, EFTS is complete). 2. When new submissions are detected, they are sent to the Websocket (t4g.micro websocket, using Go for greater concurrency). 3. Websocket sends signal to consumers.

Archive:

1. One t4g.micro instance. Receives notifications from websocket, then gets submissions SGML from the SEC. 2. If submission is over size threshold, compresses with zstandard. 3. Uploads submissions to Cloudflare R2 bucket. (Zero egress fee, just class A / B operations). 4. Cloudflare R2 bucket is proxied behind my domain, with caching.

RDS

1. ECS Fargate instances set to run daily at 9 AM UTC. 2. Downloads data from archive, then parses them, and uploads them into AWS dbt.medium MySQL RDS. 3. Also handles reconciliation for the archive in case any filings were missed.

Some are projects that have a changing variable over a long period of time (Framingham Heart Study, E. coli long-term evolution experiment) or strive to exist a long time (Clock of the Long Now). I would argue that these projects -- their process, data collection methods, and goals -- may have been developed quickly, in a short amount of time. Their longevity is proof that the original project was well established. But the same could be said of the invention of the wheel, shoe, sliced bread, etc

> because this doesn’t magically solve the housing crisis

It does. Twenty thousand units represent about 5% of Denver's housing stock [1]. Commit to adding this many units to the housing stock every year for the next 10 years and you'll have solved the housing crisis. (You'll probably need to bail out recent homebuyers, who will be permanently underwater, but that's a separate issue.)

Coupled with LogoFAIL and most hardware shipping with insecure debug keys.. has Secure Boot ever provided meaningful security? It sure causes all sorts of practical problems.

> Lowering the rent stops people from becoming homeless which is a necessary element of ending homelessness.

Sure but by this reasoning you could justify any effort as sufficient. At some point you have to make the personal judgement on what effort is enough. I don't really see any effort focusing on anything short of homelessness as worth the oxygen in the room it consumes.

Sure. I'm passionate about turning off my computer at 18:00. And I'm passionate about not hurting our customers. These two go hand in hand: I work very hard to avoid prevent doing things that are likely to cause incidents, as those hurt customers who are not at fault, and they often mean I have to stay late.

I guess you could say I'm passionate about testing and observability, though that doesn't really describe how I feel. It just puts me in a sour mood when something breaks and we could have prevented it with better practices from the start.

I used Perl extensively for small-network (~25 boxen) sysadmin and local/personal tooling, but never in cluster/multi-node deployed production. It gave too much freedom for expression making it difficult to "team-scale".

I stopped using it circa 2000 for no real reason other than Python was easier for teams to adopt and common modules became well-maintained enough where CPAN was no longer a competitive advantage. It also helped that Guido lived and worked a few minutes north in Reston, VA back then.

That said, I still "think" in Perl regex to this very day. ;)

Thanks, I updated the text putting the US bit in parentheses.

For black-list/white-list replacing with block-list/allow-list (also more descriptive) is a a clearer example of the rationale to change the terminology. In general it is about the whole range of feelings and perceptions around "dark" and how they lead to biases in people, often without being aware. If we become conditioned that uses of "dark" invoke gut feelings of sneaky, shady, illegal, secretive, nefarious, evil, etc. some of that may seep through in how people with dark skin are considered. Whether that is true or not, in any case, the alternative terminology being more descriptive, it is low-hanging fruit to adopt it.

Anecdotally, I came across a large (for a single user) quantity of diesel 9 years ago. (Nothing exotic - a company went titsup and I was the only one both bidding for and capable of removing the diesel from their premises within an acceptable time frame; I got approx 80% off the pump price at the time.)

I still run my tractor and Land Cruiser off the stuff; the tractor had an outing today. Granted, neither of those engines are very particular about the fuel they are given, but still...

(Water drained off every few months, also a biocide is added to keep the diesel gunk at bay.)

If they spent any amount on it. The long-run equilibrium is managing housing prices like the Fed, with a commitment to building enough to keep median real home prices flat. (I'd argue for a one-time adustment to pre-Covid levels. But that's arguably an arbitrary threshold.)

As both a long time Perl and long time Python user who has seen both used in production, here are some of my thoughts:

Perl

- Was an easy jump from bash to Perl

- Perl never felt like it "got in the way"

- was WAY too easy to write "write only code"

- that being said, I learned Java first and most people found MY Perl code to be very legible

- regexes as first class citizen were amazing

- backwards compatible is GREAT for older systems still running Perl (looking at you banks and some hedge funds)

Python

- Forced indentation made it MUCH easier to read other people's code

- everything is an object from day one was much better than "bless" in Perl

- no standard way of setting up an environment for MANY years hurt

- sklearn and being taught in universities were real game changers

FLUX.1 is one of the most popular open weights text-to-image models. We distilled Krea-1 to FLUX.1 [dev] model so that the community can adopt it seamlessly into existing ecosystem. Any finetuning code, workflows, etc that was built on top of FLUX.1 [dev] can be reused with our model :)

I think at some point there will gradually be a line that divides consumer type devices and Workstation with a capital W type devices. If nothing else it'll encourage the PC market to really decide for each use-case how much they value having a huge range of laptop or pre-built configurations or being able to assemble from parts. There's a lot of momentum in the PC mindset, but I also think a lot of people would be satisfied with less 'personal' so long as they were able to identify what they need and match it to capabilities of a model. 20 years ago the idea of a phone/table as the personal computer for most people and not a PC/laptop would be silly, yet here we are

How are NPs not just the trend of enshittification? Most doctors already aren't very engaged in the tiny 15 minute slices of appointments, and now we're supposed to be happy that they'll be even less educated? The most straightforward way to address the doctor shortage is to make it so doctors are spending most of their time on healthcare, rather than appeasing "insurance" company bureaucrats with onerous paperwork.

One of the most important startup lessons to learn, in perpetuity, is not to underestimate email.

I learned this the hard way when I was running a startup 15 years ago (we used sign in with Twitter and didn't required people give us their email address) and it's still true today.

Email is almost universal, mostly free from gatekeepers and is an incredibly effective way to keep your product relevant in a way that doesn't depend on your users remembering to visit your site or open your app.

There are people out there who don't use email, but they tend to not be people who spend serious money on the kind of products most startups are building.

But then you're just shifting the cost somewhere else. The doctors aren't working for free. Someone is paying them. It's just not the patients in the case of free clinics.

In addition, doctors aren't the only cost centers in health care either. Even if they're free, which is sort of already the case or fairly inexpensive for the insured in the US, the overall cost of healthcare will still be high.

Plus if you want completely free clinics (everything from doctors to medicine, etc), then you're not talking about a market solution to the issue, which is completely fair too. No one said you have to use a free market solution for this problem.

My point is that we can't expect a free market to solve this issue. It isn't as simple as supply and demand.
by hangonhn | 2025-07-31 21:29:54+00:00
Completely fair point. I should have prefaced my statement with US based healthcare system is structured this way. I don't know how the dynamics are in other countries -- though I do suspect it's similar in term of information asymmetry. I imagine doctors everywhere have some pretty advanced and specialized knowledge. I don't know enough about India to know how they overcome this issue or if they do or not.

I mean its not that much different from a diesel generator, they are around 30% efficient, so they'd also be kicking out the same amount of heat?

That's neat, I'd never considered one could use udev reactively like this! Very nice.

Not nearly as elegant, but I keep running into problems where I want to run some command when X happens. I've been trying to lean into systemd, creating a service for whatever it is I want run (perhaps just a oneshot if it's a a one off command). Then have a separate program that detects for the desired condition (polling?) and runs systemd-notify to signal that it's healthy. Then you can just BindTo=, so that the desired command runs whenever the condition-detector thing goes green.

Extracting uranium from seawater gives you natural uranium, which needs to be enriched for use in most power reactors. The reactor under discussion here needs higher uranium enrichment and more expensive fuel fabrication operations than common power reactors. Developing uranium extraction from seawater is a good long-term insurance plan for uranium availability, but it's not going to help this reactor get its fuel costs down.

I would expect that a protocol such as TCP performs much better than QUIC in benchmarks. Now do a realistic benchmark over roaming LTE connection and come back with the results.

Without seeing actual benchmark code, it's hard to tell if you should even care about that specific result.

If your goal is to pipe lots of bytes from A to B over internal or public internet there probably aren't make things, if any, that can outperform TCP. Decades were spent optimizing TCP for that. If HOL blocking isn't an issue for you, then you can keep using HTTP over TCP.

I got into game engine development knowing full well that it’s “applied linear algebra” and not at all like playing a game… except when you need to test something a hundred times in a row.

Lots of my colleagues dropped out of the industry in their first year because they didn’t like maths at all.

What really drove the point home for me though was that a decade later I got more satisfaction out of developing ETL pipelines for multidimensional analytics.

Think about how “nuts” that is! Everyone likes playing games but nobody installs SQL Server Analysis Services on their home PC for “fun”! Yet… it is, for a certain very select subset of the population…
