t_tsonev··on The AI-Native SDLC Playbook
The article text doesn't fit on an iPhone screen, but sure, code is a solved problem.
t_tsonev··on Googlebook
"Works" is kind of generous. Try connecting a printer for example.
t_tsonev··on How an oil refinery works
The article is quick to point out the huge role of oil in the modern energy mix. It also fails to note that most of the energy ends up us waste heat. The so called "Primary energy fallacy". Other than that, it's a great read.
t_tsonev··on Tesla is committing automotive suicide
There have been significant advances in power electronics and electric motors in the recent decades. Yes, there's not a lot to gain when you're starting at 85%+ efficiency, but it's far from "basic" technology.
t_tsonev··on Adoption of EVs tied to real-world reductions in air pollution: study
What you're missing here is that oil production and processing has huge fixed costs. Producers can't just pump out infinite oil at zero cost. The economies of scale break down and fuels become more expensive as demand drops.
t_tsonev··on Launch a Debugging Terminal into GitHub Actions
Why SSH to the build agent when you can run your actions locally using the excellent https://github.com/nektos/act
t_tsonev··on IPv6 just turned 30 and still hasn't taken over the world
The problem with private address ranges is that everyone thinks they're available. In a large enough enterprise you're bound to have conflicts. They usually pop up at the most inconvenient time and suddenly you're cosplaying ARIN in your IT department.
t_tsonev··on Scaling LLMs to Larger Codebases
I'm okay with writing developer docs in the form of agent instructions, those are useful for humans too. If they start to get oddly specific or sound mental, then it's obviously the tool at fault.
t_tsonev··on Nuclear energy key to decarbonising Europe, says EESC
But you can compare generated power, right?

> In the 12 months to June 2025, wind and solar (2,073 TWh) generated more electricity than all other clean sources (nuclear, hydro and bioenergy) combined (1,936 TWh). Just four years ago, wind and solar generated half as much electricity as other clean sources combined.

t_tsonev··on Nuclear energy key to decarbonising Europe, says EESC
Those are not really great construction examples, are they? Both projects took 15+ years to complete with huge cost overruns. And for those two "successful" projects, you can find 2 or 3 that failed.
t_tsonev··on In New York City, congestion pricing leads to marked drop in pollution
Specialized EV tires are also optimized for drag and noise, wear is just a factor. Anecdotally speaking I'm at over 80k km on a set of EV tires with at least 20k more to go. The issue has more to do with driving style and engine power than any other factors.
t_tsonev··on A supersonic engine core makes the perfect power turbine
No fundamental reason not to power them with renewables, either off-grid or with a small capacity grid connection. The argument that they need to run at full load 24x7 sounds more like a business requirement than a technical one. LLMs in particular with their stateless nature seem like an ideal candidate for global distribution.
t_tsonev··on A supersonic engine core makes the perfect power turbine
The final analysis is still pending, afaik. In any case maintaining grid stability is a good problem to have and likely much easier to solve than generation. Worst case, you spin some flywheels to get inertia.
t_tsonev··on A supersonic engine core makes the perfect power turbine
I'd really like to see the math on this one. It implies that building wind and solar on Earth is somehow worse than building it in space _and_ moving the data center there? It's not just counter-intuitive, it's bonkers.
t_tsonev··on Migrating Burningboard.net Mastodon Instance to a Multi-Jail FreeBSD Setup
Isolation is certainly one big reason to use jails. You also get independent management of dependencies, and can optionally share the base system.

They're somewhat similar to how you'd use Docker containers on Linux, but have different approach to security and networking.

t_tsonev··on Comparing the Latitude of Europe and America
You need a Solar Radiance map to say thay. Latitude is a factor, but so is climate.

Here's an example: https://re.jrc.ec.europa.eu/pvg_tools/en/

California and Arizona are comparable to Sahara, but Germany has much usable potential too.

t_tsonev··on I bought the cheapest EV, a used Nissan Leaf
This is not a general rule and many non-cooled and air-cooled batteries can hold up pretty well. The battery cooling becomes a limiting factor for DC charging, especially if multiple charging sessions are required per trip.

The Leaf limited battery life is mainly to its battery chemistry (LMO), although it arguably doesn't go to great lengths to ensure thermal stability of the pack.

t_tsonev··on Volkswagen locks horsepower behind paid subscription
This seems to be an UK thing, possibly to keep the sticker price below the 40k GBP tax limit. The option for a lifetime purchase supports this.

So it's an extra that you can try with a subscription and buy once, if desired. Seems fair to me.

t_tsonev··on UK government advises deleting emails to save water
Are you suggest they move them outside the environment? Sounds familiar.
t_tsonev··on Bulgaria to join euro area on 1 January 2026
Finally, some quality fearmongering on Hacker News /s
t_tsonev··on AI's energy footprint
No amount of value, in the economic sense, will solve climate change.
t_tsonev··on US Administration announces 34% tariffs on China, 20% on EU
That's true for most other places, including the EU. With services included, the trade imbalance is negligible. Source:

t_tsonev··on Why Tracebit is written in C#
Recently I've got bitten by the comically poor cross-platform cryptography support in .NET

Just look at https://learn.microsoft.com/en-us/dotnet/standard/security/c... and https://learn.microsoft.com/en-us/dotnet/framework/network-p... for a sneak peek into this madness.

t_tsonev··on Touchscreens are out, and tactile controls are back
If this is a laptop, it helps to touch the aluminum chassis or an exposed metal part with your other hand.
t_tsonev··on Battery-swap networks are preventing emergency blackouts
On-demand charging is very much happening today. All chargers communicate the available charging current with the vehicle and some can adjust it dynamically.

As for control, there are proprietary and OSS solutions (shout out to https://evcc.io/en/) that allow you to control the charging process based on price, grid load, local PV generation, etc.

t_tsonev··on The Wi-Fi only works when it's raining
Rain can improve signal quality by lowering the noise floor. Essentially, it drowns out the weaker signals originating from other emitters, making your own signal stand out.
t_tsonev··on I used to not worry about climate change. Now I do [video]
Here’s some new data for you: Russia is flaring over 4 mil cubic meters of natural gas per day.
t_tsonev··on Self-Consuming Generative Models Go MAD
It's the most likely scenario.
t_tsonev··on Fewer people are buying electric cars in the US
At these latitudes the optimal slope is 40+ degrees which is pretty steep by roof standards. I don't know how much of an issue it is in practice.
t_tsonev··on Fewer people are buying electric cars in the US
As far as the US is concerned, there are no stricly "bad" locations for solar. Even using them in Alaska makes sense.
