Fighting for effective resource usage and performance every day. Open for some random jobs, the worse ball of mud the better. Love to jump into tasks others are running from :)

From (yuck!) JVM/Spring/Kotlin, through Go/TS/C# to C/C++.

misiek08··on Can GROUP BY still be optimized after all these years?
22.2ms vs 35.6ms is 1.6x faster! It's 0.4x faster and even doing worst math possible it's 0.62x faster.

Can't we really keep the IT without breaking news/we are all gonna die/sensationalist way of passing news?

misiek08··on Tell HN: Gemini trains on chat history, even for subscribers (personal accounts)
People read privacy polices and believe them. It’s like EU cookies alerts that are automatically dismissed by 99.9% of people, accepting everything.
misiek08··on AI is forcing us to pay off 40 years of technical debt
> As far as anyone is aware, disaster has been averted: The hack was discovered by cybersecurity researchers who reported it to the PHP Foundation

Thanks to The Lord everytime someone discovers the vulnerability he reports it right to the owners/maintainers and there are no bad actors out there keeping it as secret and using for years.

misiek08··on Microsoft fixes a Windows 11 annoyance as PC revenue declines
That's why a lot of us still works on Windows 10. I'm always laughing hearing that on Win 11 even Task Manager breaks not showing process list, randomly. Clipboard on RDP breaks every few connections and requires killing process or restart. The funniest is when next person calls me and asks if he really needs creating Micro$hit account to just use PC for local stuff.

I hope someone at big corp will be so bored one day that he'll just start releasing Win 10 updates after reverse engineering the mechanisms and we will get Win 10 support again.

The rule still alive and stands strong - every second Windows is just a crap. ME, Vista, 8 and now 11.

misiek08··on Node2Shell evolves to HTTP2Shell, blast radius affects many HTTP libs and apps
They’ll have it for few months and then make you pay to get the update.
misiek08··on Show HN: I got tired of btop not seeing my Mac's chip, so I built siltop
They don’t accept vibecoded PRs and yes, it’s much easier to sit for a evening or two than to wait for maintainers to review PR in a month and wait another month or year for release. I’m not happy, but that’s the reality.

No mention of Rust in repo description and every 4 sentences?! Thanks, I’ll look at it! I didn’t know I miss those things until reading README ;(
misiek08··on 90% of US working hours are spent on tasks not covered well by AI benchmarks
I still think that AI is optimized first for the most overpaid jobs to reduce costs for the corporations and countries. What I don’t understand?
misiek08··on Thinking will become a hobby
As long as workforce is needed cheap food will be somewhat cheap.
misiek08··on 3rd Yandex Cloud Data Center Was Hit
Germans hid plane engine factories underground with old (not so efficient) diesel generators running 24/7. 80 years ago, so the tech was leaner. Also they didn’t have issues with ventilation and even today if you don’t know where - you won’t see anything driving around.
misiek08··on Telegram Desktop vulnerability allowed any user's file to be stolen
Personally - I still don’t think I’m interesting enough to even point agents to hack me and the most important… the UI feel and UX. Even WhatsApp UI and UC is better than Signal and such statement can be seen as insulting.
misiek08··on `123456' password used in Danish CPR data breach
Technically or socially? The second one is hard, the first one can be done easily - just require the passwords to be 14/16+ characters, multiple symbol domains and calculate tempo of input. Slower than 350ms between keystrokes - error message. Those who can type that fast already are using pw manager or you can just skip this 0.001%.
misiek08··on Telegram Desktop vulnerability allowed any user's file to be stolen
Still we are using it, because UX kills any other app and people that are (probably) behind it will cause almost no harm to casual, not-interesting people :)

And yes, I know that by default chats are not E2E, that phone number has way too many effects on accounts etc. Still, UX and agencies interested in important people are more welcome than data selling, ad-based companies.

misiek08··on Improper redaction reveals Google Data Center water and electricity usage
The path they are talking about solves also a lot of problems, tho. They don’t care, because they’ll already live on Moon, Mars or will be dead.
misiek08··on Rails World 2026 Opening Keynote [video]
I can’t imagine how agile apps and difficult environment you have to develop for to really feel tokens cost at implementation level. Meetings, research, PoCes and everything else eats thousands times more.
misiek08··on What algorithm did Windows XP use to choose your initial user picture?
Thanks for that. Algorithm in article looks like always choosing first picture and I was curious what magic is there behind.
misiek08··on Java 27
Saying that Go lacks in those is just showing how people are making software those days. It’s just terrifying.

As to Rust - we all, hopefully, agree that it’s great language, but not for some startup making websites or Mongo based, boring backends. It’s great for the stable, system level products.

misiek08··on Java 27 Released
I’m not sure how long it will take, but please - can we stop saying that annotations like @IHopeThisWontBeNull is a toy for kids and, having so many years of incidents caused by those and having LLMs to write and fix the code, we can rely on language and compiler already?
misiek08··on My business partner sent a 5K vibe-coded PR that he didn't even test
"no worries man I know what I'm doing" it’s first sentence in AI-using human mouth that tells me to turn around and run. I’m using models, I’ve built two whole projects without looking at more than 1% of code, but I’ve tested the interface and went through data on disk to verify the assumptions. Sad to see you have a FRIEND who behaved this way.
misiek08··on CEO fired developers to make room for AI. Developers create open source AI CEO
So.... is it overpaid.lol[1], but this time real implementation? :)

misiek08··on Building an (almost) fully self-hosted, sandboxed, agentic software factory
I would love to know what Claude model was used to one-shot the gym app. My observations lately show that only top model is able to do that, a e.g. Opus got dumber after Fable premiere.
misiek08··on The road to ACID transactions in Cassandra 6
Second that question not only to OP/GP. Comparing Scylla and Cassandra - the choice is obvious, but current offering is a complete no-go.

Also Mongo is catching up in the use case we have and it’s even more scary. We are all the time at the exact edge of Mongo scalability and I’m talking about very good, few-years-invested-in setup on NMVe that is really delicate…

misiek08··on There's no such thing as a small software team anymore
So you are already sometimes being the „meat proxy”. It only shows one much worse thing - the people asking you are first to blame/for, because they didn’t ask LLM. Maybe it’s temporary and it will change.

One added value I see in senior knowing how things work is simple - in case of outage or business incidents (caused by incorrect logic produced by LLMs from even worse prompts or incomplete spec) senior can act faster and answer difficult questions live. Now we are going to have bunch of kids looking at „Hallucinating…” and „Crashing the prod…” status bar in CC CLI.

Maybe this is what’s gonna be acceptable and it’s just new world.

misiek08··on We replaced Redis with MySQL for inventory reservations and it scaled
We observe 200+ (can’t say closer number) purchases per second for single SKU with good marketing and price.

The other thing that bothers me - why not real stable, but maybe „too old, medieval” solution with Redis as the main source of through - without any sync with SQL at all in terms of stock… it worked in my previous job with much higher traffic (1000s/s). Yup, we ended up with app-side sharding, but it was stupid-simple.

misiek08··on Choose DuckDB rather than SQLite
You new to the world, right? ClickHouse proven being a beast for analytics, tracing and even some basic metrics storage (VM won of course, but still CH is probably 2nd or 3rd)
misiek08··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
It’s still a thing in big corps. We have all business nanoservices (I can’t call them micro) at JVM (moving to Kotlin from Java) and any try using Go is silently killed by those JVM talibans.

I wonder if no one really thought there about rewrite that will still connect with all old dependencies with old protocols, but also will expose new kind of API that can be used by next rewritten block.

We also had mainframe, we used Oracle. It turned out that casual server is also reliable in long term and we restarted them only for upgrades of OS. Of course moving to some distributed, fault tolerant option also feels like good direction, but instead not-doing the perfect rewrite at once you can do it two/three step migration. Costs nowadays? You already fixed that.

misiek08··on Show HN: I replaced a $120k bowling center system with $1,600 in ESP32s
I would love to see some blog posts and/or videos about this!
misiek08··on Show HN: I replaced a $120k bowling center system with $1,600 in ESP32s
While reading all about cameras and other sensor I would try to use distance-driven sensors every where. Standing pin vs laying one have enough height difference to not mislead even simple distance echo-based sensor. Other techs I see more reliable are LIDARs, because they don't require lighting. Pure camera should have enough light to see the pins (or you have to do some IR based markings and IR camera) or you can't make the space darker for events etc.
misiek08··on Claude Fable produced a counterexample to the Jacobian Conjecture
So IIUC no one really worked on that in „professional” or rather university world since then?
misiek08··on Is this the end of the once-mighty GoPro?
Garmin will survive a year or more easily, because in Europe there is a big group of people who belive in Garmin even more than people belived in Apple (this group is still huge and strong, but the company itself does everything it can to change it).

The real competition is Apple Watch and for sport-intensive application Garmin wins because of battery and simplicity of usage in harder conditions.
