truekonrads··on When random is not actually random enough
PRNG is the answer, if you want over a set of small numbers (say a 100) to get a nice distribution of your choice , then you shouldn’t use a RNG, you should generate the desired points on the curve and then shuffle them (or use deterministic code to that effect). A true RNG can output any numbers and only over a large set of numbers the distribution would be uniform.
truekonrads··on How Delhi cut electricity loss from 50 to 5 percent
Re Estonia - it is integrated into EU wide power grid, 99% households have smart meters, reliability is 99.99% etc, all of its grid is inspected by drones. The only thing Estonian grid hasn't done is achieved sentience.

truekonrads··on Where's the Beef?: The lab-grown-meat revolution that wasn't
Vegetarian for 10+ years. Love the odd impossible burger, otherwise I don’t miss meat or fish at all - the thought doesn’t enter my mind
truekonrads··on Where's the Beef?: The lab-grown-meat revolution that wasn't
Why eat meat at all is the big question? Impossible and Beyond satisfy the taste and craving without the nastiness.
truekonrads··on Reverse Engineering Unknown File Formats with ImHex
My few rules are: 1) What's the entropy? This helps with encrypted/compressed. You probably need to overcome this? 2) What's the context? Apps are developed in context and context suggests formats. Is it C? Then expect structs. Does it need to go over the wire? Expect run-length encodings. Python/JS - JSON/pickle. 3) There are broadly speaking only a few ways you can read data back into memory: fixed layout, run-length encoding, terminators. A great case-study is ASN.1, once you've built an ASN.1 parser by hand no file format will ever daunt you.
truekonrads··on The Indo-European Family Tree
Cool viz. However it’s hilarious to classify living, spoken languages as “proto” - Latvian and Latgalian. It’s like: “despite there being 2M speakers you guys don’t quite qualify as proper Baltic”.
truekonrads··on Microsoft builds MacBook Pro rival with NVIDIA-powered Surface Laptop Ultra
Surface devices last 6 months in tropical climate like Singapore and then something breaks.

truekonrads··on Decisions that eroded trust in Azure – by a former Azure Core engineer
What were the issues behind "APIM down"?
truekonrads··on Postgres Postmaster does not scale
Cool debugging, but… 1) if you have very spiky loads (on the hour) and you can distribute them a little it’s obvious that this is will be good thing. 2) they had the answer all along in their telemetry Sometimes wisdom beats effort
truekonrads··on Defeating a 40-year-old copy protection dongle
The problem seems the sales model rather than the dongle:

1) a hardware and software solution implies that hardware will stop working at some point. Customers should understand it 2) you could sell them a new dongle every time support contract ends which is what I’ve experienced with Xways as an example. Even if you’re air gapped once a year usage data upload and new dongle seems fine. 3) why should users receive free upgrades and bug fixes? No software is bug free.

Finally there are several brand protection shops that fight fakes and work well with Shopee, Lazada, Facebook etc. It’s not five dollars but they will take these down effectively

truekonrads··on CRISPR fungus: Protein-packed, sustainable, and tastes like meat
This is not how the overwhelming majority of chickens live - they live in high intensity farm operations in horrible conditions
truekonrads··on Amp, Inc. – Amp is spinning out of Sourcegraph
I love AMP, it delivers great results. I like that it’s opinionated in how it should be used and for example tells me that I need to hand off context.

I love that I am not welded to one model and someone smart has evaluated what’s best fit for what. It’s a bit a shame they lost Steve Yegge as their brand ambassador. A respected and practicing coder is big endorsement.

To anyone on the fence - give it a go.

truekonrads··on Advent of Sysadmin 2025
I absolutely love the sadservers. Can’t wait for windows version.
truekonrads··on Adversarial poetry as a universal single-turn jailbreak mechanism in LLMs
The writer Viktor Pelevin in 2001 wrote a sci-fi story "The Air Defence (Zenith) Codes of Al-Efesbi" where an abandoned FSB agent would write on the ground in large text paradoxical sentences which would send AI enabled drones into a computational loop thereby crashing them.

It’s all about the libraries in the end.
truekonrads··on The paradoxical efficient market hypothesis (2024)
In systems thinking there’s the concept of “stocks” or “buffers”. Meaning that change of inputs into the systems first affect stocks/buffers before the outputs.
truekonrads··on Cloudflare Email Service: private beta
Deliver via sendgrid*, receive directly is probably the only viable path for self hosted systems.

Where sendgrid=any major player, could be Mimecast, proofpoint or anyone else who will forward outgoing email.

Copilot 365 conserves tokens a lot which is why results are bad.
truekonrads··on Show HN: Tritium – The Legal IDE in Rust
Hi! Tech/cyber person at a law firm here. Major concern I can see is “will this make the formatting go haywire”? Also which kinds law practice groups would benefit them most. Finally - how can this be collaborative ?
