Show HN: I made an affordable email verification service
Hi HN!

I wanted to share a project I've been working on for a while.

As a developer, I've experienced the frustration of seeing email campaigns land in spam folders or bounce back due to outdated or invalid email addresses. Email still is a powerful outreach medium, and we shouldn't have the fear of getting blacklisted. Instead, we should focus on writing that great email.

That's why I've created Heybounce. It is a fast and affordable email verification service with an API for developers and a no-code tool for list uploading and cleaning.

It blocks fake signups (disposable emails). Removes inactive and invalid email addresses. Cleans spam-traps and honeypots.

If you have any questions about the product or any feedback, feel free to write them below, and I’ll be more than happy to answer them.

They aren't effective because truly being effective was not the goal.

It's about having a program that's easy to scale, low maintenance and cost. Whilst it seems at least good enough.

McMindfullness era has made things cheaper, but also diluted products no longer be properly effective.
> I always thought a nation as rich as ours should welcome a lot more refugees.

Well, I think your fellow citizens are not happy with the levels - "Nearly six in 10 people now agree “there’s too much immigration to Canada,” according to the country’s longest-running survey on the topic by the Environics Institute. It’s the first time since 1998 that this view is held by a clear majority, and a stark shift from favorable opinion over the past two decades."

I often dont have the competence and time so selective comments are often more informative for me
For though-hole components which I use with my breadboard and for small bolts, nuts and washers I have glued together a few dozen matchboxes and inscribed them with component description.
For SMD resistors/capacitors I use an organizer box. Components within a certain range go into the same compartment together. For example, I have three compartments for resistors: ≤1k, 1k..≤10k, >10k.
SMD ICs are all in one box, each type in its own plastic bag, inscribed.

I also have a registry of everything I have. When I buy or use something, I update the registry.
Thanks for your detailed reply.This seems daunting but I will look into it.
> A higher level of preemption enables the system to respond more quickly to events; whether an event is the movement of a mouse or an "imminent meltdown" signal from a nuclear reactor, faster response tends to be more gratifying. But a higher level of preemption can hurt the overall throughput of the system; workloads with a lot of long-running, CPU-intensive tasks tend to benefit from being disturbed as little as possible. More frequent preemption can also lead to higher lock contention. That is why the different modes exist; the optimal preemption mode will vary for different workloads.

Why isn't the level of preemption a property of the specific event, rather than of some global mode? Some events need to be handled with less latency than others.

>Fast reliable unit tests are difficult

Not difficult if you build your code (not just the test suite) around scheduling APIs (and queues implementations, etc.) that can be implemented using virtual time instead of CPU/wall clock time (I call that soft vs hard time).

Actually I find it a breeze to create such fast and deterministic unit tests.

Smells like reinforcement learning in real life. Master sets ups the task environment, collects samples from students, picks the best and maybe even augments them. Students watch the master and learn... and the cycle continues.

And then the master becomes a grandmaster (unless entropy explosion occurs).
>“In Japan, companies are traditionally strong – what your employer says goes,” he says. “And Japanese people are generally reluctant to rock the boat. Resigning is seen as escaping and evading your responsibilities. But that is changing.”

Oh man.... wait until the youth hear about the US custom of Job Hopping every year to get better pay. The labor markets everywhere are shrinking as people like me are yeeted, or age out of the supply.

No wonder the Japanese model is to have a job for life... you're a serf in that model.

> The point is that this is a data structure and not a web server.

URIs are not only used on web servers though, they're all over the place, probably most notable your filesystem is using `/` as a path separator, so it wouldn't be completely out of place to use it as a path separator elsewhere.
Yes, and it does it by starting an instance of the old version and runs pg_dump against it. And that was one thing the original poster complained about.
There's no real delete, just add a status: archived for "deletion" and you 're fine, nothing else to learn.
That's a funny post, since your other reply in this thread is:

Yes. Surprise surprise, most businesses generate most of their initial sales via cold calls/emails/DMs/other automated marketing. That’s the real world
> Helix, the editor? How would you pitch it?

Not the OP, but Helix is a minimal fuss modal editor with sensible defaults. My config is maybe five lines? I say "maybe" because I haven't looked at it I first wrote it. And I think I'd probably be just fine with no config.
Implementing an Intermediate Representation for ArkScript
For a while I wanted to explore new optimization opportunities for ArkScript, and so I wrote a very simple IR for my language ArkScript (lisp like that’s made easy to embed in C++ apps).
I’m now going to improve this IR (to have function calls directly in it, so that I can do some inlining)!
I believe Chrome is also the only software that enables certain mitigations such as ProcessSystemCallDisablePolicy on Windows and NO_SMT and TECS on macOS [1]. I wonder if some of these OS features have been implemented at Google's request.

However, in the case of Spectre, I think the OS should try to prevent exploitation rather than end programs, with a user-facing toggle to disable mitigations per-program for compatibility reasons.

As if. I've been doing my own research, following a youtube channel that reveals the hidden truth about PLT PIs. Most of them are into brackets and even experiment with bisimulation, but worst of all are their grant sources: they're clearly in the pockets of Big Step.

This would be a tremendous amount of steel for the size of building they are creating.

Crude steel production in 2023: 18.88 billion mt. 20% = 3,776,000,000 metric tons.

If you just laid that on the ground in 1 meter square blocks it would cover a 481km² area (steel mass=7850 kg/m³). If you made a 1m² block tower, it would be enough to reach the moon, wrap around it, and start heading back.

Their original planned area is 26,500 square km, though this has been scaled back to 1.5km long.

I struggle to see how 481,019 m³ of steel will fit in an area 1.5km square without being the largest and tallest building ever constructed. If you just made a block of pure steel in that 1.5km square area it's going to be 320m high (about half the height of the world trade center across an area the size of 40 Manhatten blocks).

Yes, exactly, while the average USian might still keep up with the rising costs of healthcare,

(and in fact being the cause of rising costs because that is where they are going to spend their disposable income),

the median USian will not.

Partially this also comes from statistical effects that aren't scale-invariant :

Countries with more people are more rich (including per capita).

Countries that are richer are more inequal.

Countries with more people are more inequal.

I was debating someone, not asserting that I know the answer.

They were speculating whether there could be a copyright violations vs for instance using a tape recorder or a video camera.

I made an example that yes if there is a copyright violation here it is, and that’s it’s not that different.

I could have pillowed my language differently sure but what’s the point. It’s clear in context.
10 minutes reading into the madness of this project, it's claimed sustainability, and you realize that the amounts to be spent there, and the fact that it's build on the necessity to solve dozens of huge technological hurdles, make it a pure waste of money.

This is a project championed by MBS himself, and no-one dared telling him it was nonsense. Architects and consulting companies are doing what they do best with these types of pie-in-the-sky project: play along and take the money.

The vision is a nightmare of population control and surveillance. It wants to be sustainable, but go cool nearly 150M m2 of glass walls in one of the most inhospitable hot environment for humans... and tell me this is sustainable.

There are flying pods and glow-in-the-dark sand scapes...

Nothing in that project is energy efficient or makes even little sense. It's a vanity project. The money could have financed real breakthrough in science and engineering. Instead, it's wasted moving sand around. They won't even be able to build and host the 1.5km they now target.
> Japan’s chronic labour shortage – a symptom of its low birthrate – has also made employers more determined to retain staff, even if it means intimidating them into staying. Some force workers to find their own replacements before accepting their resignations or rip up their resignation letters in front of them.

You'd think that in a market economy a labor shortage would result in rises in wages and improvements in working conditions because labors hold more leverage in negotiations. And yet.
A mention of "cofounder dating app" made me stop and thing wtf is wrong here.

Knocker uppers: Waking up the workers in industrial Britain (2016)
My friend Jim's been fixing stuff since the 1950s. He's got a lot of boxes for specific Radio types, etc... a few "Collins" boxes, etc.

For fixing IFR stuff[1,2], he's got a few dedicated under the desk roll out clear plastic drawers with all the spares, etc.

All the Tubes are in boxes in trays in the closet, in random order.

Resistors, are sorted, in drawers by value, clearly marked.

Capacitors are separated by type and voltage. He's got a few boxes of 450 volt electrolytics for all the tube gear.

All the semiconductors are in a few drawers with the IFR parts.

Then there's the shelving with parts radios, etc.

> Air travel is a privilege, not a right. If you can't afford a ticket, don't fucking buy it.

They did buy the ticket. Legally.

> Sure, but that's not skiplagging.

That literally is the same as skiplagging. Skiplagging is only determined on intentions, not actions as it is the same action.

> If skiplagging becomes more common, airlines will ultimately raise prices for everyone to make up for the inefficiency and everyone loses. Screw that noise.

You should be more mad about people flying for cheap with credit card points, that literally DOES raise prices for everyone. But I'm sure you do that all the time so it magically makes it okay.

It's not really a technical issue, they just pretend it is. It's an abuse by the employers, and that's not something you can fix with certified mail.

Likely they just find a way to make the certified mail not work when it is in your favor, while of course it works perfectly when you get delivered some notice of trouble for not showing up at work.
Looks nice but requires a LOT of printer time.
user fldsk means to say 6000 year history, of course. But I'm willing to come down on that, since Genesis is a bit of a chronological hand-wave.

If we grant that Italy is Rome, which is a separate conversation, then we're still left with Roman conquest, which we don't consider legitimate today, and a long period of documented Jewish inhabitation.

I don't take a position on the legitimacy or otherwise of Israel, because there are already plenty of indignant westerners with insufficient information. But I will say: that written history is weighty evidence.
Opportunity cost. Anthropic's deal is in training Claude and whatever they choose to call their next model, not whatever weird little niche you're going after. I might not go after programming, but, say, a dnd character backstory generator would be a wrapper that's probably not interesting enough for them to build themselves to compete with yours. Or maybe it is, but your DND character backstory generator also doesn't have to use anthropic as the backend, there are others for you to choose from, so it's a bit of a standoff.
Agreed - as organizations scale, it's like some kind of fundamental law of thermodynamics that says they must become more bureaucratic in order to remain competitive. I think it's because organizations can only work at scale if they minimize the variance of each individual business unit, and malleability threatens that. I still think that good enough leadership and communication should allow for malleable units to coexist well together, but that may be a naive ideal.

I think the idea here is to build a thin layer but BYOD.

I currently work for a company where most our value add lies in the data collection, cleaning and running of proprietary algorithms. A UI like this would be a game changer for us and something that Anthropic couldn’t easily replicate due to all the IP in our data pipeline.

Because nothing motivates them. It’s mostly chinese money but also US. Stop giving them it and find a better use, simple. Or say something like “I’ll buy it, if you do X”. That’s motivation. They will say “nah, if we do X, Y, you just don’t understand”. Etc etc. It was probably all said before and we are just exploring naive ideas on how the world should work.

Europa Clipper Heads to Jupiter
In Austria you can eg end your Apartment lease via a specific court form that removes all ambiguity to wether they have received this in time or whatever. It cannot be refused since it is not filed with the landlord directly but served to him by court. Since Austria requires you to specify a known address to the government it is basically your problem then if you are not present. It is mostly used if your rental agreement contains language in conflict with the law about when you can end the lease. It basically reverses the roles since they cannot refuse the cancellation only appeal it and companies will obviously not do that based on leases that contradict law. You pay 100 EUR so you don’t have to communicate any more about it with the landlord which can be quite the good deal
For example in Spanish, there's been always a fight between using "cifrar" instead of "encriptar". I like "cifrar" a bit more, but it's true that we've always had the prefix "cripto-" for hidden or mysterious things. Anyway, the difference is "cifra" is the Latin root for "digit", and "kryptos" is the Greek root for "hidden".

I would indeed (like Altman promised for OpenAI; 'we're gonna steamroll you'), implement all these cases (and many more) on their side, so their 'chat' becomes a full toolkit for building, visualising, prompting etc and allow people to plugin their data/processes (maybe with a few partners for that part which they can easily replace or have multiple of).

Currently, the "Added to project" button that remains for n seconds and you have to wait for to add another file (sometimes Claude generates 4-5 files per chat) is such an annoyance that I guess they should stick to training and nothing else.

Its a matter of debate how much exclusivity should be granted and for how long.

But the key idea stands: an inventor who invents something rare and non-obvious should be rewarded, supported, and encouraged to invent again. Or not?
This isn't really trying to emulate copy-on-write though. It's intentionally making a copy temporarily to mutate it further whilst keeping the original ready to be mutated on the next tick. They share superficial similarity but that's about it.

As a random tangent, whilst memcpy in the general case is going to be O(n) given that in this program the n is a fixed size the operation in context is always going to be O(1). Fundamentally though it's not a very good way to compare the performance profiles of the approaches to this problem on real hardware.
