ToucanTix | Senior Ruby on Rails Developer | REMOTE (EU/US timezones preferred)

Your code will run the gates at zoos and theme parks across Germany and the USA. When families scan tickets, when capacity limits kick in based on visitors and available resources (staff, equipment, facilities), when dynamic pricing adjusts for weather - that's our Rails app making real-time decisions for thousands of visitors daily.

We're 5 engineers at ToucanTix (sister company Combase has 80+). You'd have serious ownership and architectural influence from day one.

Technical challenges that actually matter:

Multi-tenant architecture supporting 100+ venues with wildly different business logic. Offline-first POS that syncs flawlessly. Complex pricing rules (weather + season + capacity + customer type) that need to stay performant. Hardware integrations with access control and payment systems.

Stack: Rails 7+ API with GraphQL (graphql-ruby), PostgreSQL doing serious heavy lifting with multi-tenant architecture, Redis for speed-critical stuff, SvelteKit frontend (if you're full-stack curious), Google Cloud infrastructure (Cloudtasker, Cloud Storage), RSpec/Capybara keeping everything bulletproof

You: 5+ years Rails. Strong at PostgreSQL optimization. Have architected systems for performance and scale. Comfortable owning technical decisions.

Us: Real ownership. No layers of management. Async-first remote culture. Profitable company, not burning VC cash. Your work has physical impact - people literally can't enter the attraction if your code breaks.

Full details: https://www.toucantix.com/careers/senior-ruby-on-rails-devel...

Apply: jobs@toucantix.com - Send CV + one technical challenge you're proud of solving. Put in subject line.

> The fact that people have started applying social-justice-y terminology ("gatekeeping," "weaponize," "shared experiences," etc) to medical diagnosis is a clear sign we've gone too far.

Standing up for people that you see being mistreated, insulted, or disrespected isn't "social-justice-y" it's basic human dignity and compassion.

The way you choose to disagree shows how much respect you have for other people. I don't agree with you is very different from, you're wrong to think that or say that. Every single person should object when they see someone punching down.

What alternative to having a defense/war industry and stockpiling significant amounts of armour and arms intended for state sanctioned violence do you propose? Where do the actions of the current governments of the PRC, Russia and North Korea figure in this proposed setup? What do you think the consequences of the transition phase (not the final result) of your changes will be? Some possible quantifiable measures of the latter include number of additional wars fought, number of additional genocides perpetrated, number of additional millions killed in conflict; but you're free to choose your own.

The phrase "power of the purse" does not appear in the constitution.

The idea that the members of the board of the federal reserve are structurally very distinct from appointed members of the NLRB or the FTC is ridiculous. It is just calvinball from the fact that the conservatives like the stability offered by the fed and don't like most of the other independent agencies that do things like empower unions and fine people committing financial fraud.

I think we are still in the period where many new jobs are being created due to AI, and AI models are chiefly a labor enhancer, not a labor replacer. It is inevitable though, if current trends continue (the METR eval and GDPval) that AI models will be labor replacements in many fields, starting with jobs that are oriented around close-ended tasks (customer service reps, HR, designers, accountants), before expanding to jobs with longer and longer task horizons.

The only way this won't happen is if at some point AI models just stop getting smarter and more autonomously capable despite every AI lab's research and engineering effort.

I said it in another comment and it's in many reports, but per Senate rules they need a 3/5th majority (60 votes) to pass the funding bill. One Republican voted against, two Democrats and one Independent for. That brought it to 55-45. The Republicans absolutely could change the rules, and don't require that same supermajority to do so, so this is squarely on them.

The same thing happened in 2018 when the previous shutdown happened, also with Trump in the White House and a Republican majority in both houses. The Senate Republicans lacked a supermajority and did not change the rules, and the government shutdown for 35 days.

The linked Discord post is also interesting and fun to read. Most of the post is more serious but this is one of the small gems:

> One thing we discovered very quickly was that [world cup] goals scored showed up in our monitoring graphs. This was very cool because not only is it neat to see real-world events show up in your systems, but this gave our team an excuse to watch soccer during meetings. We weren’t “watching soccer during meetings”, we were “proactively monitoring our systems’ performance.”

https://discord.com/blog/how-discord-stores-trillions-of-mes...

It is linked as evidence for Discord using "less than a petabyte" of storage for messages. My best guess is that they multiplied node size and count from this post, which comes out to 708 TB for the old cluster and 648 in the new setup (presumably it also has some space to grow)

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)

In education, we have always traded off scale and quality. In a 30-student math class, half of kids are ready to accelerate while half are still working on their foundational skills, but teachers cannot be in 30 places at once, giving each student one-on-one support.

Until now. Imagine 30 teachers in every classroom—that's how Goblins feels. Students draw math on any device, and our AI figures out the "why" behind their confusion, giving instant feedback and building conceptual foundations. (Preview: https://youtu.be/SH9UomzBMUs)

Goblins launched to school districts in the spring of 2025. Since then we've built a waitlist of thousands of teachers and sold Goblins to districts across the US (we'll hit 100k+ paid students this year!). We are in the unique position of having a product that is both highly differentiated and demanded :)

Technical problems we've worked on in the past:

→ Building knowledge graphs that adapt to student performance in real-time, routing them to the optimal next problem they should solve to maximize learning and engagement.

→ Extending our handwriting recognition from digital canvas to real paper through Chromebook cameras (think real-time OCR on math equations through low-quality webcams with poor lighting and limited CPU).

→ Creating interactive mathematical lessons (think 3blue1brown, but conversational) that remediate student misconceptions.

You'll be joining founding team members Sawyer (CEO, former Head of Design at X1 [acquired by Robinhood] and math teacher) and Alp (CTO, ex-Stripe and Amazon), plus two other exceptional founding engineers.

We move fast, care deeply about craft, and obsess over delighting users. If you're interested, email alp@goblinsapp.com :)

This is a nice PR fluff piece for something that already exists. Google ‘compact directional drill’ for a number of examples from manufacturers that have been around for a long time with established customers that trust them.

-Ditch Witch (founded in 1949, owned by Toro)

-Vermeer (private, in business since 1948)

-TT Technologies (private, in business doing microtunneling/microboring since 1990)

Directional boring contractors buy the big $2M truck mounted rigs because 99.9% of directional boring is commercial or industrial. For the tiny fraction of customers that are adding a ground source heat pump to an existing house, they’ll have one well so they don’t have to worry about pipes being too close together. Directional boring isn’t required for geothermal in new builds, trenching and backfilling on a greenfield site is going to cost substantially less than directional boring.

There are also trailer mounted hydrovac/water jet excavators, you still need a ton of water so you’re limited by the minimum tank size here.

Well it's not exactly a parody. The next season of Silicon Valley not only continues the cheeky hijinks and ironic saves required to navigate tech-cap dysfunction, it is a reality show. Although some of the new core team characters are (openly) unfiltered chatbots.

Including a real-life LLM "resurrection" of the fictional Erlich Bachman, created as part of a successful espionage mission to steal a Chinese deep learning company's near impossible distillation technology. But despite its trove of valuable illicit information, it has been orphaned online, unable to find its mysterious SV-fan hacker creators. As a result, chatErlich is now desperately attempting to make contact with the original SV team actors, who it actually believes are their fictional counterparts.

Have any HN autists here had any luck with Folinic acid as an adult relieving some of the aspects of the condition?

Leucovorin, a prescription/medical form of Folinic acid, was mentioned recently by RFK Jr./HHS as an effective treatment for some forms of childhood autism.

Politics aside, I recently saw some anecdotal cases of marked immediate improvement in young children.

https://www.tiktok.com/@cassie.hudgins/video/755601851016659...

Has anyone tried the over-the-counter version as an adult? The over-the-counter version which seems to be basically the same compound as Leucovorin, just not produced in a medical setting and exacting medical standards.

PS, please don't just downvote, reply to the comment instead with your objection or correction to what I wrote (if you have one)

I'm glad you posted. When I hear masking described like it is in this simulator: "To keep your job and avoid conflict, you must "mask." Masking means hiding your natural habits and feelings, while imitating the social behaviors that coworkers expect.", I always think, "isn't that just life?" If I didn't hide my natural habits I wouldn't be going to work at all. If I didn't hide my feelings I would yell at the person in the office next to me for listening to some webinar through their computer speakers and their door open. If I didn't imitate the social behaviors that coworkers expect I wouldn't wish the person I barely know happy birthday.

>what's the point of Democrats compromising on a package of budget laws, when the Republican party keeps conspiring to break the very laws they agreed-to but don't like?

At this point, think of it as continuing to gather the moutains of supprot for the next impeachment trials. For when a scandal happens that Trump can't recover from. From if something untimely happens and power shifts. his won't just be forgotten to history.

It's slow and painful, but when words don't work, you point to actions. Trump has done a lot of actions out of the blue that will bite back had when the power is ceded.

On linux it uses IFUNC resolved at load/dynamic relocation time, so at runtime it's the same cost as any other (relocatable) function call. But they're "static" in that it's not a calculated address so pretty easy for a superscaler CPU to follow.

So it does have some limitations like not being inlined, same as any other external function.

I understand how annoying it is when people post shallow dismissals of your work on the internet, but please don't give in to the annoyance when replying. It makes the thread worse, and it's against the HN guidelines: https://news.ycombinator.com/newsguidelines.html.

I don't know if this is your work or not, but I appreciate your wanting to defend it...we just need you to do that in a way that doesn't attack others, no matter how wrong they are or you feel they are. Easier said than done of course, but we're all working on it together.

Even if you want the most cynical approach - networking is an essential aspect of career development. If you stick to just "job description during work hours" you won't get far.

Building a cohesive team involves sharing interactions like this. If you truly value your privacy, I suggest you come up with an alternative thing to discuss: sports, weather, funny stories, etc.

I've certainly had weekends where I very much did not want to share what i did, so I deflected in a way that kept the conversation going.

If HR is asking about where you were at 3:15pm on Saturday, and who you were with, and whether you were using work resources at that time, I would start to worry. But a very large and generic, "so what did you do this weekend" - where you are in the driver's seat, that's not the same thing.

When I look back at previous jobs, my strongest regrets are not building stronger interpersonal relationships with my coworkers. I've since rectified that.

Think of it this way, if you must: coworker relationships are owned by the company - personal relationships are owned by the employees. When you become friends with a coworker, you acquire an asset that will go with you when you leave the company. Much like a new skill, this asset will allow you to get higher pay somewhere else.

There are any number of ways to skin that cat. In Rust, for example, values you pass, whether by value or by reference, are immutable by default. You have to explicitly mark them as mutable in the receiving function signature to allow mutation. I freaking love that as a default. Passing by reference is trivially easy, but you still avoid accidentally altering things that ought not be frobnicated.

I've found docker is as of a monstrous pet.

Docker is a monster that you have to treat as a pet. You've still got to pet it through stages of updating, monitoring, snapshots and networking. When the internal system breaks it's no different to a server collapsing.

Snapshots are a haircut for the monster, useful but can make things worse.

> the expression problem

I assume you're referring to https://en.wikipedia.org/wiki/Expression_problem . The Ars article rambles on for many paragraphs about a barely-sensible analogy that actually makes the concept harder to understand. But given that your apparent purpose is to proselytize for Julia I suppose it's adequate.

But really, you could have just said that Julia implements multiple dispatch. And people have been making do without in many different languages for decades.

> arising from its use of class-based object orientation

The language uses nothing of the sort. Unlike Java, you can write any number of globally-accessible classes in a source code file (including zero). Blame the authors.

Also, you don't even need classes to get polymorphic dispatch in Python. Check out `@functools.singledispatch` from the standard library.

> (but can’t escape insanity such as ",".join(["a", "b"]))

This is perfectly sane. As has been rehashed countless times, the method is on the "joiner" string because that way it automatically works for every iterable without duplicating code.

FTA: "Government tenants (GCC/DoD) for some reason don't support this capability, the one that Baroudi insists "does not create new data exposure risks."

So the government customers that can really strike back at MS don't get this enabled by default. Very interesting...

I would also wonder if this would trigger IT review due to data access patterns. Having copilot start accessing documents would likely trigger certain security systems at many companies that are designed to prevent corporate espionage. It seems like a good possibility anyway, I certainly wouldn't be willing to risk it just so I could generate AI slop emails.

Damn. Jane Goodall was the reason I am the pro-environmentalist person I am today. Learned about her from a young age as an "easy day TV class" sort of day, and it fundamentally shaped how I viewed the world.

This is awful news, though I can't help but to feel she really did it all the right way. Happy she was a part of my timeline.

> It is still nowhere enough. It is barely the capacity to support few hours of consumption of the European grid.

You just need to move the excess to times of high demand.

> Most of the solar production will go wasted.

Germany saw renewable curtailments (including wind) of 3.5% in 2024. I can only find reports it will reach 10% by 2030 in Germany and 10% in the EU. I would define "Most" as 50%+.

> That means that the price of the solar production will tank and go negative during most of the spring-summer period. And that is terrible as far as ROI on the production systems are concerned.

This depends on the market. The UK guarantees a price for renewables that have a Contract for Difference (CfD), so they're unaffected. I don't know much about the other European markets, so this might happen.

Any developer will account for this though, so money will flow out of renewables and into storage if there are serious issues around over capacity - unless you have schemes like the UK's CfD.

Finally, I disagree with your prediction

> we might doom the ROI of an entire industry for the decades to come

You have plenty of price signals in energy markets so I can't see a scenario where there's a complete misallocation of resources into renewablews and not storage. In addition investment predictions for renewables and storage are healthy and not of an industry in distress.

GOP apparently had enough votes to pass a budget by reconciliation. Which means the riders they want to add on, dropping Obamacare funding expansions are at minimum important enough to shut down over.

They do not seem to be acting in good faith, not sending people to negotiate any of this. Combined with the leaking presidents comments about being able to force through things under shutdown they wouldn't be able to otherwise, I think a reasonable interpretation is this shutdown is intentional and part of someone's plan.

edit: since subtext is dead its called Project 2025 and it's supposed to be a "bloodless coup" of the federal government. And if that isn't obvious by now please wake up.
