Ask HN: Where to Work After 40?
I turned 40 last month and spent the past decade working on my own startup that ultimately failed. I'm now trying to figure out the next step. Someone once said to me, Google is the place you go to retire after 40. I've done my time at various startups, and spent some time at Google. As an engineer the landscape of things is always changing and we've now moved from Cloud to AI pretty rapidly. I'm just curious to know what moves people made after 40 and what worked for them.

Ask HN: How to stop an AWS bot sending 2B requests/month?
I have been struggling with a bot– 'Mozilla/5.0 (compatible; crawler)' coming from AWS Singapore – and sending an absurd number of requests to a domain of mine, averaging over 700 requests/second for several months now. Thankfully, CloudFlare is able to handle the traffic with a simple WAF rule and 444 response to reduce the outbound traffic. I've submitted several complaints to AWS to get this traffic to stop, their typical followup is: We have engaged with our customer, and based on this engagement have determined that the reported activity does not require further action from AWS at this time. I've tried various 4XX responses to see if the bot will back off, I've tried 30X redirects (which it follows) to no avail. The traffic is hitting numbers that require me to re-negotiate my contract with CloudFlare and is otherwise a nuisance when reviewing anal

I launched 17 side projects. Result? I'm rich in expired domains
I think I'm officially a side project collector. I've had it all: A SaaS for freelancers... that I never had time to finish because I'm a freelancer. A revolutionary AI tool that I abandoned as soon as GPT-4 came out. And the famous "anti-social media social network" (spoiler: it was just me). I buy a domain name → I code for 3 all-nighters → I lose interest → I start again. My Google Domains look like a graveyard of unfinished dreams. But honestly, I've never learned so much, nor enjoyed it so much. And one day, I might release one that takes off. Or not. But I'll be ready. Any other serial side-projectors here?

Ask HN: Decided I no longer want to be a SWE – what next?
I recently spent the past six months working on a startup. We had a fair bit of momentum coming out of a well known accelerator and an idea with traction, but unfortunately the money just didn't quite show up for the seed. At 30, doing this without pay (and expenses covered) seemed like an ok idea, at least for a few months. But at this point I'm kind of done. Co-founder didn't understand why I wasn't interested working without salary anymore... there were other signs the relationship had broken down etc. Planning on letting him know I'm out near the end of this week. I started interviewing when these feelings started to get to me and... the VC from the accelerator ratted to my co-founder that they'd "heard from recruiters". This was effectively the most unprofessional breach of privacy I've ever experienced and as a result I think I'm do

Show HN: Core – open source memory graph for LLMs – shareable, user owned
I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps. The deeper problem 1. Not portable – context is vendor-locked; nothing travels across tools. 2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance. 3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried.

Ask HN: Want to leave my job with nothing lined up
I’m currently working in a very toxic environment and it’s starting to affect my life outside of work in negative ways. I have money saved up, don’t live an extravagant lifestyle, and have around 7 years of experience but I do know how challenging the job market has been which worries me. I would also be leaving my current company towards the end of the year when not many people are hiring. When asking my friends and colleagues what to do, I always get the same answer of either wait until you find something else to quit or wait until they fire you, but whatever you do don’t leave with no offer in hand. I agree with their approach in general but I’m just really burned out and don’t have the mental energy to come home from a 10 hour day and start preparing for interviews.

Ask HN: As a developer, am I wrong to think monitoring alerts are mostly noise?
I'm a solo developer working on a new tool, and I need a reality check from the ops and infrastructure experts here. My background is in software development, not SRE. From my perspective, the monitoring alerts that bubble up from our infrastructure have always felt like a massive distraction. I'll get a page for "High CPU" on a service, spend an hour digging through logs and dashboards, only to find out it was just a temporary traffic spike and not a real issue. It feels like a huge waste of developer time. My hypothesis is that the tools we use are too focused on static thresholds (e.g., "CPU > 80%") and lack the context to tell us what's actually an anomaly. I've been exploring a different approach based on peer-group comparisons (e.g., is api-server-5 behaving differently from its peers api-server-1 through 4?). But I'm coming at this f

Note: this is an update to [this]( https://news.ycombinator.com/item?id=44568529 ) "Show HN" post. timep is a state-of-the-art [debug-]trap-based bash profiler that is efficient and extremely accurate. Unlike other profilers, timep records: 1. per-command wall-clock time 2. per-command CPU time, and 3. the hierarchy of parent function calls /subshells for each command the wall-clock + CPU time combination allows you to determine if a particular command is CPU-bound or IO-bound, and the hierarchical logging gives you a map of how the code actually executed. The standout feature of timep is that it will take these records and automatically generate a bash-native flamegraph (that shows bash commands, not syscalls). ------------------------------------------------ USAGE timep is extremely easy to use - just source the `timep.bash` file from the repo and add &quo

Ask HN: MIT grad, junior dev layoffs – watching my daughter lose faith in merit
My daughter followed the playbook everyone here recommends. MIT. Programming olympiads. Strong internships. No shortcuts. She was hired as a junior developer and laid off in February. Since then, I’ve watched her confidence collapse in real time. She isolates herself. She barely talks. She spends most days in her room applying, waiting, and getting silence. I recently saw her crying alone, trying not to be noticed. That’s when it hit me how deeply this has affected her. This layoff didn’t just remove a paycheck. It removed her belief that effort correlates with outcomes. Every rejection reinforces the idea that none of what she did mattered. It’s Christmas and we aren’t celebrating. No decorations. No pretending things are okay. I’m completely shattered as a parent, mostly because I don’t have answers. I told her for years that merit would protect her. It didn’t. So I’m asking this commu

I am concerned about the future. Are you?
My children are in college pursuing STEM degrees (CS and Robotics), with one also pursuing an art double major (animation). While we are in the US, we also have family in Europe and Latin America. So, what's the concern? Well, there are two that I think should be obvious. The first is how AI will alter the landscape. It is easy to see that companies might be able to develop products with somewhere between 1/5 to 1/10 the engineers in the not-too-distant future. Let's define that as the time required for a fresh high school graduate to finish a Masters degree. How can you possibly advise and guide a young person given the huge variability of potential outcomes 6 to 10 years out? The second is the massive deindustrialization of the West (again, this isn't US-centric as Europe, Latin America and others are deeply affected) as China solidifies into a dominant positio

Show HN: A library to convert+deploy existing agent projects as MCP servers
Most of the MCP servers that I’ve seen are tools implemented in standalone projects. To onboard more tools (especially agents and multi-agent workflows) to MCP, I’ve been thinking it’s important to allow AI engineers to continue to prototype in their existing agent frameworks and deploy with minimal conversion when ready. We created the automcp library, which you can add as a dependency to existing projects (CrewAI, LangGraph, Llama Index, OpenAI Agents SDK, Pydantic AI, mcp-agent currently supported but more coming soon). You just need to run a CLI command to create a run_mcp.py file, make some edits and run it to start the server locally. You can think of run_mcp.py like Heroku’s Procfile, Codespaces configs, Pulumi/AWS CDK style IaC. We also created a demo of a deployment platform where you can enter the GitHub URL of your project, deploy with one click, and get a URL for the hos

Show HN: We Built Our Own Chart Type for Live Dashboards
Most analytics tools give you 10–15 chart types and call it a day. But what happens when none of them actually represent your data well? We ran into this when building a CRM dashboard. We wanted to show how sales reps connect to open deals: not just totals, but actual relationships. A bar chart was too flat, a table too dense. We needed a network graph. The problem? Most chart libraries and BI tools don’t support that out of the box. You either say “no” to the feature request, or you hack together a standalone visualization that breaks the product’s flow (no filters, no interactivity, no theming). So we built it ourselves, but in a way that still plays nicely with the rest of the dashboard. Luzmo now lets you define your own chart type, write your own visualization code, and then drop it into the dashboard editor like any other chart. Luzmo still handles the boring stuff: querying, filte

Is anybody still using TUI applications for business? My family company is a wholesale distribution firm (with lightweight manufacturing) and has been using the same TUI application (on prem unix box) since 1993. We use it for customer management, ordering, invoicing, kit management/build tickets, financials - everything. We've transitioned from green screen terminals to modern emulators, but the core system remains. I spent many summers running serial and ethernet cables. I left the business years ago to become a full time software engineer, but I got my start as a script kiddie writing automations for this system with Microsoft Access, VBA, and SendKeys to automate data entry. Amazingly, they still have a Windows XP machine running many of those tasks I wrote back in 2004! It's brittle, but cumulatively has probably saved years of time. That XP machine could survive a nu

We got a $60k tax penalty for a zero-revenue side project
In 2020, in the middle of COVID, a few friends and I decided that obviously the world needed another presentation tool. Our pain point was simple: we hated fighting with PowerPoint/Google Slides. We just wanted to write content and get nice slides without babysitting fonts, sizes, alignment, colors, and 19 different "Title + Subtitle" layouts that all somehow looked bad. So we built a prototype: a tiny click-together slide builder. Then we decided clicking was too slow and turned it into a full markdown-to-slides thing. Write markdown in, pretty slides out. Easy. Then, like every good side project, we started bolting on features: Image uploads, PDF generation via API, AI integration and more and more stuff nobody had actually asked for.... Somewhere in there, in peak "we're definitely the next unicorn" mode, we incorporated a US company through Stripe Atlas.

Show HN: A word of the day that doesn't suck
I’ve long thought that the Word of the Day was a wasted genre. The goal should be to give you words you can use; to enrich your understanding of words you already know; or at least to use words to tell you something neat about the world. Instead, what you usually get is words that will never be used in conversation, held up as curios. Some examples from Dictionary.com’s daily email: thewless, balladmonger, vagility, contextomy. These words are... not useful. I’ve always thought I could do better.

It’s a pretty involved question and looking up “marquee tech startups” or "hot tech startups" on Google gave me nothing useful. Deep research on both ChatGPT and Perplexity gave really high quality responses with ChatGPT siding on slightly larger scaleups and Perplexity siding more on up and coming companies.
