Fat FIRE devs

Your Postgres database is at 95% disk usage. You delete 1 million rows but disk space doesn't decrease. Why not and how do you reclaim space? [We faced this last quarter]

10 super practical tips to ace 95% of your Senior Backend Engineer interviews in the age of AI in 2026 (and beyond).

You added caching and your memory usage grows until server crashes (OOM). Cache hit rate is 95%. What's wrong with your cache implementation? [Topic: Memory Management]

Just talked to a person via my 1:1 call and he said that after 9yrs of experience he is still not staff. He works at a reputed company but writing APIs in python. I suggested him to use AI to get better at system design etc and also get better at understanding the fundamentals. And tbh this is more common than people think. 9 years of experience does not automatically become Staff. A lot of people spend years doing scoped API work, closing tickets, staying reliable, but never intentionally building the skills that higher levels actually demand. Staff is not just writing more code. It is system design. It is driving ambiguity into clarity. It is taking ownership beyond your Jira board. It is influencing roadmap, mentoring people, seeing tradeoffs early, and communicating well with managers and teams. He said he is earning 27 LPA fixed which is not some disaster tbh. It is a decent base. One solid switch with better prep can move that to 40 to 45+ LPA very realistically. But the bigger point is this: - Stop thinking in "how do I escape next month" - Start thinking in "what can I become in the next 6 months" - Use AI daily. - Study fundamentals properly. - Practice system design. - Do Leetcode consistently. - Talk more with your manager. - Ask for ownership. - Get closer to architecture and decision making. Most careers do not change in one interview. They change when someone spends 6 months very seriously becoming a different engineer. Consistency looks boring in the moment. But in software, boring consistency is what usually creates the big jump. --- You can book 1:1 call if you want: topmate.io/abhishek_singh… Practice System Design for free: 0xffdevs.com/design Read interview Experiences: 0xffdevs.com/interviews Follow pathways: 0xffdevs.com/pathways And invest and buy the community token on Solana: 0xffdevs.com/token --- Thanks for reading.

@sir4K_zen @0xlelouch_ There's a big fat roadmap section in there

@0xlelouch_ @0xffdevs Nice build, free learning paths rock. What's the next milestone?

I finally completed building @0xffdevs over the past few days - a learning platform for devs who want to code their way to financial independence. pathways for Go, Rust, Solana, system design. interview stories. a free system design canvas. jobs board. all free. We also launched a token on solana via market on @orynth so the crypto community can be a part of this ambitious, community driven project. Just a way for the community to have skin in what we're building together. Official CA(can be found on the wesbite too): 7bGT4zV1XfaDrjCGNDA5Tghsy83cJSaiqQhwmBBGory checkout 0xffdevs.com and start learning some niche skills, do checkout the roadmap for what's coming next! some exciting things in the pipeline!! Seeing some good growth for a platform launched yesterday

We are live! You can also connect your wallet and list free resources in the marketplace! We are working on adding a paywall feature here!

@mewudi669 @orynth I see. Let me do that asap

@0xffdevs @orynth You must personally post it on the main account; some people say you've deployed it several times.

It's live! We launched our product on @orynth checkout 0xffdevs.com for the official token address!

93.5% of Senior Backend Engineer interviews are just these 7 concepts repeated again and again.

90% of React interviews are basically the same 10 topics.

In the AI era, code and generic answers are abundant, but lived engineering judgment is still scarce; that is exactly why @0xffdevs exists. We’re building a place where builders share practical pathways, real interview outcomes, curated resources, and grounded discussions so people can learn from actual experience, not just generated summaries. AI can accelerate execution, but community context, taste, mistakes, and hard-won lessons are what turn information into direction, and 0xffdevs is designed to preserve and compound that human signal! Here are some more updates on the product of the year 0xffdevs.com > Unified Connect now supports both Discord login and MetaMask login, and shows whichever identity is active. > Discussions are now Discord-first, showing only general with the latest 10 messages. > Discord feed auto-refreshes every 30 minutes, with manual refresh anytime. > Resource requests are routed directly to Discord, so submissions land instantly in the team channel. > Subscriptions can be handled with Discord/webhook workflows as a free lightweight backend layer. > Marketplace supports wallet-connected listing and browsing in a single flow. > Wallet-based interactions (where needed) remain available without blocking public content access. > Core community ops are now consolidated through backend APIs + Discord for faster, low-cost shipping. > A completely transparent roadmap section to show what's coming! More integrations coming soon! Visit: 0xffdevs.com --- Would love to have any feedback, feel free to join telegram, discord and discuss and request resources (can be done from the UI too).

@gvanrossum It's prompts and an ide

I think I finally understand what an agent is. It's a prompt (or several), skills, and tools. Did I get this right?

Every time I read stories like this, I understand a little more why so many software engineers want to leave India. It is not just about salary. It is about basic dignity. You study hard, crack interviews, work night shifts for global teams, pay huge taxes, sit in traffic, breathe bad air, and still a bad road, broken system, or one random failure can destroy your life in seconds. That is the real issue. Indian engineers are not leaving only for dollars or pounds. They are leaving for working infrastructure, cleaner systems, better public safety, more predictable rules, and a place where the state does not take so much from you while giving so little back. And while all this is happening, the rupee keeps getting weaker. The rupee recently fell past 94 per dollar, and the RBI reference rate for the pound was around 126.2 per GBP on 27 March 2026. That means if you earn only in rupees and do nothing with your money, you are getting poorer slowly. Maybe your salary did not fall on paper. But your purchasing power did. Imported goods get costlier. Foreign travel gets costlier. Studying abroad gets costlier. Global assets get costlier. Even just comparing yourself to someone earning in stronger currency becomes painful. This is why being a good employee is no longer enough. You need: a second income a side business equity freelance work a digital product content consulting something that scales beyond your monthly salary Because salary alone gets taxed first, inflated later, and devalued silently. Harsh truth: if you are only working, only saving in cash, and not building anything on the side, there is a good chance you are moving backward without realizing it. Build skills. Build assets. Build income streams. And legally optimize taxes as much as you can. In this economy, doing nothing is also a decision. And it is an expensive one. It's just sad.

Let's make it clear once and for all. I would rather have AI-generated content provide value than using a faceless girl pic and posting random opinions about soft boobs and what not (with 30% verified followers). For my account, verified followers represent less than 10% of the total. It seems people are drawn to this platform for entertainment, even with readily available, dumb alternatives like Instagram. Coming to the AI content part. I get DMs every day on LinkedIn and X from people who really enjoy reading me and getting value out of this account. I use AI to rephrase/proofread what I write and I accept it. Imho, if you are using LLMs to enrich your experiences, you are missing a lot!

If serverless (Lambda, Cloud Functions) eliminates infrastructure management and auto-scales, why run any servers at all?
