@david__smith__ haha, long way to go still... I had to take a route midway, to avoid it from looking like a clone of bigger databases... ended up choosing clarity and visibility.

my latest project is done and I tick off my bucket list of having my own database. sceptre - a transparent embedded relational database engine, the whole stack... from raw disk pages up to a SQL layer, all from scratch. here's what's under the hood: - fixed-size page storage with dual meta pages and checksums. - copy-on-write B+ tree for ordered key/value storage. - freelist so deleted pages get reused instead of lost. - typed tables, primary keys, secondary indexes. - a query planner that picks table scans vs index lookups. - commit interruption recovery, tested deterministically, not just hoped for. - full inspection CLI: decode a raw page, walk the freelist, trace row flow through execution. and the part I'm most proud of: the observability tooling. you can run a query, see exactly which rows were scanned, which stage took how long, and then drop down to the raw page bytes to see why. benchmarks on 100k rows: - table scan: 246ms, 100,000 rows scanned - same query with a secondary index: 14ms, 1,429 rows scanned - 70x fewer rows touched. 17.6x faster. - crash recovery: 20/20 cases clean and it's built in Go. zero external dependencies. single binary CLI with a built in shell.

If Linux is the best, why does it have such a small market share?

so far , I think the majority of AI tools really did almost nothing to have a great truly useful impact on the majority of society in everyday life it feels like it is just an abstraction layer over everything that we already have promising you could do it a bit more easier I feel like we dont really even need that easier anymore the deterministic software systems we had before really solved most comfortability we could have as majority of society it was simply just a great helper for people who were already doing their things productive and right

@rxhit05 potential networking opportunites in universities are underrated most of the time there are more talented people than you think who are most likely somewhat interested in the field you are pursuing the degree in

I think it depends on the depth level of the software ur building, but for most of the projects , it tends to be a coping mechanism for the great dopamine hit we used to get from solving problems by hand on our own but neglecting the power of these models even combined with programming knowledge is just clearly not the way

The urge to learn [zig, rust, go] by-hand right now is incredibly high. Not because I think it's a better way to build software in 2026 (it's not) but because it's SO MUCH FUN. Remember the feeling of learning your first language? Your second? Third? How the intuition about language features and design steadily developed and helped you become the engineer you are today? Speaking of which, need to choose a topic for next stream series...

first of all , the only cryptocurrency that is truly good for illegal reasons is monero public ledgers and kyc linking most of the cases is not really the most pro-illegal thing why would you not want to hold some crypto which is now the only way to get some sovereignity over the centralized banking system what is melted in every financial activity nowadays why would you not crave some independence at least financially

Owning cryptocurrency is insane. Like are you some kind of criminal or something? There is 0 good legal reasons to own cryptocurrency. 100% of the good reasons are illegal. Like seriously illegal. Like hiring hitmen illegal

DeepSeek just dropped a 1.6 trillion parameter open-source model with a 1 million token context window. OpenAI is charging $200/month,China is giving it away for free. This changes everything.

@fardeentwt I didnt really understand this ever obviously people like to join groups just to feel they belong somewhere and get some form of identity cheaply but if you go deeper you always realize nuance and there is no one objective truth in anything like this everything is subjective

@icanvardar too many abstractions these days to notice how amazing it is to solve almost any problems and put it in front of real people thanks to a computer

programming is still fun you just forget it sometimes when you get buried in tools, frameworks, and opinions at its core, it’s still just you and an idea turning into something real

@Param_eth we need useful and fun projects on existing chains rather than tge slops but that would require a studying of the tech and the whole ecosystem which is harder than only thinking in terms of tokens and red and green lines

99% of crypto projects lie. - They're not decentralised - They are useless and have no utility. - They won't change the world. They are just here to launch a token and rug you I love web3, but I don't want a TGE everyday.

AI promised to do the work for us so we could enjoy our time doing other things. Since llms, me and everyone ambitious around me has been working harder than ever. I don't think this stops anytime soon.

@gregisenberg thinking about this every single day in the past year I made the most amount of progress with my goals in building but I know the potential is 100x more it amazes me and gives me anxiety at the same time everyday

You know what fires me up? That this is the greatest time ever to build a company (thanks to AI). My first startup I built in college took 1.5 years to build the prototype. When I hit 100 users I was so happy i was literally in shock. Today, you can hack a product in 24 hours and wake up to 1000+ strangers already using it. You can post a stray thought, record a selfie vid and millions might see it. Words, code, distribution. It all feels like a giant multiplayer game. The rules are clear, the moves repeatable, the rewards compounding if you keep playing. Kinda feels like a treasure hunt. One post can change your career. One prototype can become a company. One company can snowball into a movement. All in a few clicks. You rack up points. Except now the points are customers, revenue, and freedom. It doesn't matter where you come from, what school you went to, what jobs you had. As long as you got fast internet, you can play. Startups used to be for the privileged and now they're for the persistent. And that fires me up. Maybe you too. Pretty amazing.

Sorry to say, Lazarus Group is the top hardworking smart contract security auditor in the world. Other auditors charge $50k and miss critical vulnerabilities. These guys work for free and never leave any money from the contract. Their resume: • Bybit: $1.5 Billion • Drift: $285 Million • WazirX: $235 Million • KelpDAO: $292 Million • DMM Bitcoin: $308 Million • Axie Infinity (Ronin): $625 Million And many others.
