I built this because I watched my LangChain agent burn ~$50 in OpenAI credits overnight due to an infinite loop.It&#x27;s a middleware API that acts as a &#x27;Flight Simulator&#x27;. You send it your agent&#x27;s prompt, and it runs adversarial attacks (Red Teaming) to catch loops and PII leaks before deployment.Code &amp; Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;Saurabh0377&#x2F;agentic-qa-api" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Saurabh0377&#x2F;agentic-qa-api</a>

As various LLMs become more and more popular, so does comments with &quot;I asked Gemini, and Gemini said ....&quot;.While the guidelines were written (and iterated on) during a different time, it seems like it might be time to have a discussion about if those sort of comments should be welcomed on HN or not.Some examples:- <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46164360">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46164360</a>- <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46200460">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46200460</a>- <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46080064">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=46080064</a>Personally, I&#x27;m on HN for the human conversation, and large LLM-generated texts just get in the way of reading real text from real humans (assumed, at least).What do you think? Should responses that basically boil down to &quot;I asked $LLM about $X, and here is what $LLM said:&quot; be allowed on HN, and the guidelines updated to state that people shouldn&#x27;t critique it (similar to other guidelines currently), or should a new guideline be added to ask people from refrain from copy-pasting large LLM responses into the comments, or something else completely?

Ask HN: Should "I asked $AI, and it said" replies be forbidden in HN guidelines?

Throughout 2025, I&#x27;ve been following job boards like YC Jobs, RemoteOK, NoDesk, WeWorkRemotely, and others. Across all of them, I keep seeing a recurring pattern:Many companies advertise &quot;remote&quot; roles, but hiring is limited to the US, Canada, UK, or Germany. Sometimes they add one or two more countries, but rarely anything beyond that.Given that it&#x27;s the last quarter of 2025 and remote work is more established than ever, I&#x27;m trying to understand the reasoning behind this.A few questions I&#x27;m hoping founders, hiring managers, or people with international hiring experience can shed light on:- Is the main blocker regulatory complexity? (employment law, compliance, local registrations, PE risk, etc.)- Is it primarily about taxes and payroll overhead when hiring abroad?- Are there security or liability concerns that make certain jurisdictions easier to work with?- Is it simply the cost of maintaining compliant employment structures worldwide, or are there deeper strategic reasons?- And finally: Is there evidence that the value produced by strong engineers abroad doesn&#x27;t offset those costs, or is the issue not economic at all?I&#x27;m asking out of genuine curiosity, from the outside, it seems like a global talent pool should be an advantage, especially for remote-first companies. But the hiring restrictions persist, even as tools like Deel, Remote, Oyster, etc. mature.I&#x27;d love to hear perspectives from people who have dealt with this firsthand.

Why are "remote" jobs in late 2025 still limited to hiring in US/CA/UK/DE?

I have been purchasing used&#x2F;new Lenovo&#x2F;Dell laptops for the last 7 years, and I have noticed that the build quality of recent models is concerning.Lenovo: Ex-company gave me a NEW Carbon X1 around 2019, and the battery only lasted for less than a year (!). On the other side, I bought a used 2017 470S from the same company, added more RAM, didn&#x27;t touch anything including the SSD, and I&#x27;m still using it in daily coding. I did buy a new battery last month so technically the old batteries lasted for about 7-8 years.Dell: I bought 3 laptops + 1 desktop from Dell Refurbished (So the quality should be consistent). 2 laptops + 1 desktop are older models, and 1 is Precision 5550 (2021) that I bought last December. Everything works fine, except for the 5550, which has issues with battery (dropped from 31% to 4% in a few seconds) and (more deadly) charging port (doesn&#x27;t charge from time to time). Even if I bought it new in 2021, I would be surprised that it only lasted for a bit over 4 years.The other issue is that 5550 uses USB-C ports. I blame on myself not checking it closely before the purchase. I really hate those ports. Why is everyone copying from Mac?What&#x27;s my option? I can&#x27;t really justify the 2,000+ CAD price point for a new laptop, especially if it lasts less than 5 years. I&#x27;d prefer a &quot;low-end&quot; workstation with 32GB memory, but because of the price point I can only afford a 16GB non-workstation one. I don&#x27;t do gaming any more but I still prefer a good integrated video card. I can&#x27;t afford Framework and other Linux laptops because they are expensive and usually don&#x27;t operate in Canada so delivery is expensive too.I did buy a used Macbook Pro M1 16GB (2021) from my current company last month. I haven&#x27;t used it but I&#x27;m confident that the hardware is good. The problem is I don&#x27;t really like the software, so I figured I still need a Linux box.Did you find any sweet spot?

Ask HN: Quality of recent gens of Dell/Lenovo laptops worse than 10 years ago?

i have a pixel 4, and it looks like i might be stuck with this phone forever if things keep going in the same direction (hopefully they don&#x27;t).
the pixel 4 isn&#x27;t bad, but even on this i don&#x27;t have the level of customization that i had back in the day with cyanogenmod etc. on my note 3 or epic 4g touch.here are some requirements that i can think of:<pre><code> - not huge. small enough to use with 1 hand

 - able to root and install custom OS without too much difficulty&#x2F;annoyance (the manufacturer doesn&#x27;t actively try to stop you from modifying your own device)
 
 - able to use mint mobile

 - has a trackball (like the htc hero, that thing was fuckin awesome)

 - possibly some hardware buttons</code></pre>

I worked with C# about 15 years ago. Due to some circumstances at work, I have the opportunity to use it again.What are some great books that could help me learn to write *modern* C#?I will mostly work with web and .NET Core, are there books specifically about using .NET Core on Linux?

I don&#x27;t know if we&#x27;re ready to pull the trigger yet, but curious if other folks are looking at alternatives.The WAF is great, but recent events have made it obvious that having a single point of failure entirely defeats the purpose of DNS being a distributed&#x2F;decentralized service.Is anyone doing anything creative here? We like the features that the WAF provides - but not at the expense of global outages. If you have a 3 9s availability SLA, you&#x27;ve just blown 90% of your allotted downtime because of Cloudflare&#x27;s WAF.

I&#x27;m a founder (and ex-architect) building a logistics OS. Recently, I received feedback that my site looks &quot;cheap and ugly&quot; because I used Serif fonts and an engraving style aesthetic instead of the standard Sans-Serif &quot;Clean Tech&quot; look.My intent was to evoke the &quot;Age of Exploration&quot; vibe, since the AI era feels like charting unknown territories. But users seem conditioned to trust only &quot;Standard Blue SaaS UI.&quot;My question to HN: Does a B2B tool have to follow the &quot;Standard Modern UI&quot; to be taken seriously? Or is there room for distinctive, maybe even polarizing, aesthetics in enterprise software?I&#x27;m debating whether to cave in and redesign to &quot;boring but safe&quot; or double down on our soul. Would love to hear your thoughts on &quot;Brand Distinctiveness vs. UI Familiarity.&quot;

Wouldn&#x27;t say nvidia sell more GPU&#x27;s if RAM prices were lowered? What prevents them from buying up IP &#x2F; RAM fab labs and commoditizing the blueprints for its manufacture? Perhaps to the public at large, or perhaps just relicensing it for very low prices to entities in friendly nations?

I see people all around me who have this bleak, pessimistic view of where everything is going. That art&#x2F;originality is fading, that technology is causing more harm than good, and that most jobs now exist to feed some mindless machine where sole goal is to get people addicted. Tech roles feel drained of purpose, and non-tech roles are being eaten away.This outlook is a stark contrast to the era I grew up in. From 2010 to 2020, tech optimism was at its peak. Despite the flaws, companies like Airbnb, Uber, Amazon, and countless SaaS startups felt like they were genuinely improving things—breaking old monopolies and building better systems.Now we have AI, arguably the most transformative technology of our lifetime, yet a lot of times the reaction seems to be exhaustion rather than excitement. Sure, people love using it, but unlike the early Internet, AI doesn&#x27;t seem like a medium for creativity. The core value feels just about compressing the time it takes to do what we were already doing.Maybe it’s age. Maybe it’s just me. And maybe I am bitten by false nostalgia. But I’m curious: how are others seeing this shift?
