"Everything flows" by Vassily Grossman. It's the first time getting into the Soviet era. Not really a history book per se but still a great FPV of the peopler that lived during that era.

Re:Show HN: Huzzah – a novel approach to coding with AI on Friday August 21, 2026 @08:41AM (#49387234)
My main problem with the current state of the editors is that either they're are bloated i.e. VS Code or they've drift out of being editors i.e. Claude Code desktop or the new agents panel that Cursor/Antigravity and others have introduced

None of the existing ones (that I've used at least) are good editors designed to work with agents.

Ask HN: What internal tools/SASS replacements are you building?

I hear more and more from people in companies of all sorts, are building internal tools/replacements of SaSS businesses.We built an automated QA agent based on Playwright, that does QA on our own products, literally in a week and we continue to contribute to it. Our QA engineers love it.What sort of things/products are you building?

Re:Mike: open-source legal AI on Thursday April 30, 2026 @02:35AM (#47958979)
For a moment I thought it was some open-source LLM trained on legal. It's not, it's a web app wrapping major LLM providers and streamlining legal workflows, uploading documents, and having the LLM providers interact with them.

Cool project regardless!

Re:A.I. is creating engineers who can't think without it on Tuesday April 28, 2026 @08:22AM (#47933522)
In "Thinking—Fast, Slow, and Artificial: How AI is Reshaping Human Reasoning and the Rise of Cognitive Surrender" [1], a third level of the human thinking process was introduced where argues that besides internal intuition (level 1) and deliberation (level 2), there's a third one which is external and is the well-known to everyone, AI.

Humans now can choose to either completely surrender to that external intelligence, called cognitive surrender or choose to just offload tasks and use it alongside their own reasoning.

It's up to us how to use it. I've recently joined a new company and I had to explore their massive codebase. Even my manager suggested that I should use an agent to help me with the onboarding but I went straight to the code and whenever I had a new task, I would explore the code to understand what is happening and then instruct the agent to do any tasks I thought should be done.

There are moments when I completely hand off to the agent without looking any diffs, but my main focus is understanding first and then handing off.

I do like Antigravity a lot and I use it on a daily basis. Are you referring to that or something else? I do find their marketing weird though and seems like their internal teams are not yet fully aligned. (Jules, Antigravity, Gemini CLI, ...)

I'm trying to do a deep dive on RAG/LLM based apps since I didn't had the chance yet.

I'm building a chat-assistant that will be able to discuss with you and find more about what's your current work status and what you're looking for. Then it will suggest best suited roles for you from the HN Who's Hiring threads.

It's still very early, I've managed to index the latest thread and there's a CLI chat tool to discuss with the LLM.

It's been great because I learned a ton already, about LLM deployments, RAG evaluation, prompt engineering, LLM internals, etc.

Re:Ask HN: Solid setup for local microservices architecture on Wednesday August 30, 2023 @01:21PM (#37325554)
Author here: just wanted to clarify that the question was meant to be for creating a local development environment.

Ask HN: Solid setup for local microservices architecture

What are some impressive setups you've seen or you've implemented on locally replicating a microservices architecture with local DBs and other backend dependencies.I'm looking into docker-compose with remote docker-compose yaml files but I'm not sure of how solid is going to be.Our services are mostly Node.js based services and dockerised already. Production environment is setup on AWS ECS.

Yeah I get that, I was looking for personal subjunctive opinions.
I'm thinking that GDP is best used for longer term periods and not for a goverments' short term term, 4-10 years. For example, a goverement could be recklessly spending money that could have an effect on GDP but that doesn't show the whole picture.

Regardless, GDP is always useful so def one of the right metrics for economic performance in general.

Def I need more studying on the subject my self.

Ask HN: How to evaluate a country's economic performance?

What would be the right indexes (or anything else) to evaluate a country's performance over a specific time period?I would like to evaluate my country's (Greece) last government performance and what real effect it had over the country's wealth and the general population.That is only for personal knowledge purposes and not for a professional/academic inquiry or something.Thank you

Ask HN: What is your agile product development process?

Dear HN, I'm a software engineer with several years of experience in web development and generally SaaS products.In all my experience, the agile product development process has been pretty much the same. For example, in my latest role, the PM will verbally or in a very short and vague document describe something that we want to build to the Engineering Manager (or to one of the engineers) and...

Re:How to transition a team from Git-flow to trunk/CI-CD? on Monday March 13, 2023 @05:16PM (#35142807)
I see you have a good suggestion but I haven’t really got what the problem is. Is it the weekly release cadence, you mentioned branch hell but tbh I’m not familiar with it, how does it look like? What are the biggest pain points?

I’m only trying to make sure I understand the problem otherwise I cannot evaluate the solution. Plus it would have make it very hard to sell it to me, if I was to take the decision.

It’s all about “listening” to the users with quotes because it doesn’t necessarily means face to face communication. Although f2f is best for relation building, it can’t really scale.

Data are everywhere these days and you should be gathering as much as you can(emphasis in can, it can be expensive). Take Google Analytics for example added to a blog, you can see your most read articles and write more of those, see where people exit and take action, setup interaction tracking and see what buttons are working best. You can do AB tests and compare results between two comment forms.

Same logic applies to a product as well.

But then it’s not just analytics and valuable information can be extracted from everywhere. Look at your DB and see what people have been storin (being cautious on prívacy laws). Gather NPS and see what feedback you’re getting from there.

Big companies usually have departments focused on data gathering and analysis, but even for smaller products, I would say that the best thing you can do is being data driven. Try to base your decisions with data that make sense.

All the best

Re:The Beginner's Guide to over­Complicating Coffee on Saturday February 25, 2023 @09:38AM (#34936984)
Same experience for me! Never worked as a barista but it was actually a super fun and educational journey to learn all things espresso and coffee.

I bought a Mignon Zero grinder and a Delonghi Dedica with a non-presurrised portafilter for about $500 for both. Both are beginners friendly and for home use. I've learned all about dialling an espresso, the amount of coffee to put it, the duration of the extraction, the amount of coffee to get out and what role the cut of the coffee plays.

I've calculated that the investment will pay back it-self in a few months, ~5-6.

Re:Ask HN: Burnt out from big tech. What's next? on Thursday February 09, 2023 @04:15AM (#34721482)
I couldn't suggest what you should do next with your life because of course that's different to everyone.

But seeing that your experience is mostly on FAANGs and big companies, have you thought of going with a smaller early-stage company? These are environments where people usually expose them selves to a broader spectrum of things, even having the ability to choose specifically what they want to work on.

Workplace politics unfortunately are everywhere, small or big companies. You can't really avoid those.

I also can't stress enough other replies here about really exploring your self outside of work. What do you like spending your time on outside of working hours? Any hobbies that take your mind off? If there aren't any, can you start exploring new activities (without necessary having to take a sabbatical or move to another place?)

Re:Ask HN: I’m falling out of love with coding on Wednesday February 08, 2023 @06:28AM (#34706717)
I remember vividly the times when I was so much impressed of every single line of code I've written that day. I would stay up late at nights just to make the perfect piece of code, the perfect UI, the perfect architecture diagram, etc etc. To me, that feeling was life-giving.

Nowadays and after lots of years of experience mainly in early-stage startup environments, I don't even care about the code or the low level stuff.

I'm trying to embody my self to the mission. I'm looking for the right metrics to watch and when these metrics are impacted by my actions (or my teams' actions because these environments tend to be very team-driven) thats when I get the same feeling as when I was writing those Visual Studio LoCs and was building those grey UIs with MS Access for data storage.

With the right mission and metrics, comes a problem. With the right problem that will motivate you and excite you, comes the solution. And the solution will be a package of the right code, the right UI, the right line of communication, the right team policies.

I've stopped using the term software engineer for my self, I prefer the term product engineer. And building the right product is my mission.

If you haven't explored that path, of changing your perspective of what gives you that feeling, maybe it would be helpful before deciding to go live in a farm. :) All the best.

I would also like to hear from people that went through that path and where that lead them because I'm still early in my career (in my 30s now).

Re:FCC Threatens to Disconnect Twilio for Illegal Robocalls on Sunday January 29, 2023 @02:48PM (#34571949)
Do companies like Twilio do anything about spam the same or similar way Google for example handles spam?

I guess that they are not obliged to deal with it at least in most countries. I honestly don't know much on this space but this article raised my curiosity.

Re:How to Create Luck on Wednesday January 18, 2023 @08:21AM (#34426297)
But meritocracy has more to do with capabilities rather than needs. We could argue that you've actually deserved what you got because you've worked for it (by fighting your depression and coming out to say yes to more things). You def proved that you are capable of overcoming it.

Btw I'm not arguing against the people that are in need and under-privileged, I totally get your point on that.
