That may be the written goal, but I doubt that's the actual reason the project exists.
scblock··on Rules, Not Renewables, Might Explain the Iberian Blackout
That is correct. There are no modern utility scale turbines that are directly coupled to the grid. This was at least initially to allow for variable rotor speed at a constant grid frequency.

Some use doubly-fed induction generators which take about 1/3 of the power through an inverter at variable frequency back through the rotor to create stable 50 or 60 Hz output (Type 3 machines), while others do full scale conversion (Type 4 machines)[1].

FERC 827[2] details the power factor requirements in the US for non-spinning (mostly renewable) generators, most easily summarized as power factors from 0.95 lagging to 0.95 leading at the high side of the transformer in the project substation.

scblock··on Rules, Not Renewables, Might Explain the Iberian Blackout
Renewables can absolutely provide and consume reactive power through the use of power electronics equipment incorporated into the inverters. All modern utility-scale wind and solar power plants use this type of equipment, and most interconnection requirements in the US require significant reactive power capability as part of the interconnection process. This may require additional reactive power capabilities such as capacitor banks, DVAR units, or reactors at the project substation.

This means if grid voltage drops they will provide VARs to increase voltage, and vice versa. They can similarly react to shifts in grid frequency. Only after they reach certain power factor, voltage, or frequency limits will they disconnect from the grid, similar to other generators.

If in spain renewable energy projects were somehow exempted from needing to provide a wide range of power factor capability then yes this would be a rules problem.

They charge more for inductive loads because of low power factors and significant VAR consumption yes, though you can also do power factor correction on induction motors. And though most wind turbines use induction generators, they are designed to be able to supply power at unity power factor and through a large power factor range.

Also, islanding means operating as a standalone grid, which does not happen when the generators shut down, and systems are designed to shut down after a certain number of cycles without grid. This does not sound like islanding at all.

scblock··on Menstrual tracking app data is gold mine for advertisers that risks women safety
This comment in this thread explains it fairly clearly. Do not make the mistake of thinking this is just a semantic difference.

Then you haven't tried looking. Women are being arrested and even convicted for having miscarriages, including in the US.

scblock··on Ask HN: How do I take an LLM with me when I go camping?
I don't know that this is really a good idea, but if you insist then LM studio is a good tool for local LLMs and has nicely formatted output. Smaller 4B models will probably run fine (they do on my M2 Pro at least). I prefer it to ollama, and it makes tuning the system prompt and temperature easy.

Others will probably have better model recommendations, I am using Mistral and Gemma myself.

scblock··on The Decline of Battery Life (2021)
Well, first this should be marked as (2021).

The rest is just a bunch of BS anecdata that definitely does not tell the story the author wants it to tell. The chart is sorted by battery life rather than date which really muddies the picture. Looking at the dates I don't see "the decline of battery life" but rather "battery life is highly variable but devices are getting more efficient as they get more powerful".

Progress in the last 4 years (through mid-2025) shows this post has aged poorly even if the premise had been supported by the data. Many handhelds gaming devices get over 6 hours continuous play, and several like the Odin 2 have larger batteries and can get 10-12 hours easily. And they can be recharged from typical USB chargers.

scblock··on Real ID is a waste of my time and I don't need one
I live in one of the majority of states that simply made this part of the state ID process years ago, and I'm struggling with the way decades later this is apparently still such a huge ordeal for some.

The article talks about not wanting to give more of your personal data and yet advocates for getting a passport or passport card... So, do the same basic thing and share the same basic data with the same basic government? What principle is being upheld again?

"Just use your passport", sure if you have one. That's fine. Passports are the gold standard. But not all Americans have them, they need to be renewed, they are anything but free, and they take time and effort to obtain.

And the end of the article, with the author acting like they're clever for using their passport at the airport? TSA agents see them all the time, like every day all day. Of course it's fine.

scblock··on My quest to make motorcycle riding that tad bit safer
Agreed, I was more responding to the idea of tying into existing sensors or motorcycle data as noted above. The light I mentioned is part of a bigger lighting system that works through a CAN interface and has all kinds of control of settings through a somewhat convoluted overlay on existing bike inputs, like press this switch, then these, then turn the wonder wheel to adjust brightness.
scblock··on Samsung is paying $350M for audio brands B&W, Denon, Marantz and Polk
Ah, so just like with AKG they'll get rid of everyone who knew anything and then slap old (and already lower tier through their own lack of efforts) audio names on hot garbage.
scblock··on Ask HN: What's your favorite text editor on Mac and why
Here are my personal choices and what I use on my Mac:

Paid: BBEdit

Free: Kate, after jumping through Apple's ridiculous "unknown developer" nonsense to approve it to run.

scblock··on My quest to make motorcycle riding that tad bit safer
An existing brake light product, the Billy light from Clearwater, integrates with the BMW canbus to pull the bike's acceleration data and use that as a basis for what this light appears to do.
scblock··on Office is too slow, so Microsoft is making it load at Windows startup
FYI "the few games that work" is most of them these days, including newer games like Baldur's Gate 3 and Elden Ring and older ridiculous towers of cards like my heavily modded Skyrim setup. I think it's mostly things that use invasive anti-cheat software that struggle. I use a mix of Steam and Heroic Games Launcher and haven't run into anything I've been playing recently that doesn't work except my PSVR2 to PC adapter in Steam, which I haven't taken any time to troubleshoot.
scblock··on Two publishers and three authors fail to understand what "vibe coding" means
That's because it doesn't mean a god damned thing.
scblock··on Why did Windows 7 log on slower for months if you had a solid color background?
On my fairly recent corporate laptop a 30 second login would be massively faster than my corpo-malware-ridden experience. 5 minutes to Windows 10 desktop this morning.

A similar (slightly older) laptop I own boots from fully off to the KDE desktop in 25 seconds total including typing my password.

scblock··on A $20k American-made electric pickup with no paint, no stereo, no screen
A more reasonable comparison is probably the hybrid Maverick, which appears to be popular (at least around here), has 4 doors and actual features, and starts at around $25k.
scblock··on A $20k American-made electric pickup with no paint, no stereo, no screen
Looks like a concept that will never actually reach the market.

And if it does and I'm completely wrong, this concept is probably doomed anyways, as it is swinging far too far to the other side away from fancy tech and right into uselessly bare. I'm sure a few people are excited by this, but realistically it will have a tiny real market. Nearly no one wants manual windows and leaving them out isn't saving huge amount of money.

Make it comparable to a decent conventional vehicle, but electric, and you may do well. This though is more useless and non-functional than my old Jeep, which has a trip computer and bluetooth as the biggest "tech features".

scblock··on The Truth about AI and copyright that nobody will say out loud
Garbage. Has a lot of discussion that goes nowhere, then says "you have to subscribe to keep reading."

I see no reason to keep reading. I regret having started.

scblock··on A student accidentally broke the laws of thermodynamics while mixing fluids
No one ever broke the laws of thermodynamics. What is this garbage writing?
scblock··on Google says all upcoming Google TV remotes will have a 'Free TV' button
It's always great when your shitty streamer or TV's dedicated button for a service goes to a dead product. What a great idea, and a great combination with Google, well known for killing products.
scblock··on Switch 2's new "Game-Key Cards" are the worst of digital and physical
They're also functionally identical to my PS4 disc of Cyberpunk 2077 which is nothing more than a license; the PS5 version of the game and all updates were downloaded, nothing is loaded from the disc, but the game only works with the disc.

Considering how strongly Miyazaki cares for human art and human effort, and his past thoughts on early efforts in this space, he would likely consider this an abomination.

What experts?
scblock··on Sports Illustrated to Roll Out Athletics-Linked Wagers Market
Sports betting has ruined sports for me completely.
scblock··on 931 Laid off at Block (Formerly Square) based on performance
"The second and biggest bucket, 460 people, is for “performance” reasons, with Dorsey explaining that Block is laying off employees who score a “below” rating on the company’s internal performance tracking metrics, or were trending towards it."

Anyone who has ever worked at a big company knows this is bullshit. I think people would prefer to not be lied to like this.

scblock··on Ask HN: Why Are We Fighting AI Scrapers If the Internet Is Meant to Be Public?

scblock··on VPNs on iOS Are a Scam (2022)
1. Should be noted as [2022] or [2023] at best

2. This is about "VPNs" which are not true Virtual Private Networks but more anonymizing or semi anonymizing gateway services.

I use a WireGuard VPN to connect to services at home from my phone that I don't want on the public internet, and that is an actual VPN in the classic sense. And in this use case I don't want all traffic to go through it because that would be annoying. VPN infrastructure was designed with this case in mind and this paid service approach (do you really trust it?) is just piggybacking on the technology.

scblock··on Firefly, the easiest using and high performance WireGuard VPN server
I'd need more info why I'd use this over wg-easy. The front is (as noted in the README) is the wg-easy front end. The one thing I see is it doesn't appear to require containers (but supports them).

This needs a real license too, the "free for personal use" statement in the README is not really an actionable license, and I wouldn't be comfortable building anything important on it.

scblock··on Ask HN: Should there be new RPN calculators to replace the TI-84?
PCalc is indeed excellent.

As for RPN, it's one of those things I didn't get until I was in my 30s and started using it. Then used it more. And now I'm at the point where using a "normal" calculator is a frustrating experience. I got very used to the stack and having intermediate results. I find it highly frustrating that the windows calculator still doesn't have it as an option, and that when asked about it the developers seemed confused why anyone would want it.

Free42 has filled the gap though.
