I am building a few catalog workflows in n8n in order to synchronize our ERP data with Akeneo.
I know it looks incredibly boring but as I progress I have to get in touch with many departments, and it raises questions about how we manage data within the company.
The people I expected to be the most reactionary about it - after all I am sticking my nose into their business - are actually the most helpful because they see an opportunity to make some tasks less painful.

There's going to be a bloodbath in that market in the next years. There are a lot of battery producers and most of them are not producing at full capacity. At the same time, manufacturing cost is dropping as well.

Some battery makers are producing batteries at a cost level of around 60$ per kwh. At that cost, the 16kwh battery would come out below 1000$ (not the same obviously as the product price). Sodium ion might push those prices even lower. Below 50$ soonish and eventually closer to the 10-20$ range in maybe 5-10 years. At that point we're talking a few hundred dollars for a decent size domestic battery. You still need packaging, inverters, etc. of course.

But the ROI at anything close to those price levels is going to be pretty rapid. And it wouldn't break the bank for households across the world. Add a few kw of solar on roofs, balconies, etc. It won't solve everyone's problems and certainly not in every season. But it can help reduce energy bills in a meaningful enough way. Even in winter.

Also worth pointing out: most of the US is south of Cornwall. The Canadian border runs roughly at 49 degrees latitude. Cornwall is the most southern point in the UK sits at 50 degrees. If it can work there, most of the US has no excuse. Also, the UK isn't exactly well known for their clear blue skies. Even people in Scotland much further north manage to get positive ROIs out of their solar setups.

I don't know how much the modern take on stoicism diverges from its historical origins, but I'm among those who believe that it ultimately pumps a delusion: that one can solve mind aches with mind hacks. Contemplative mystics (e.g. Zen, Dao) can recognize in stoicism some elemental truths --mainly that our emotions tend to be driven by the fiction created by thoughts--, but they also see it as incomplete at best and at worst, just another misguided attempt at trusting the mind as a solution architect to the problems that it creates, which often results in other subtler problems like bypassing.

Such traditions don't practice control or avoidance of emotions, but rather use them as teaching devices through aware observation when they manifest in experience (bodily sensations and thoughts). Through this "witnessing" there's realization of their fundamental nature, along with surrendering and integration of shadow elements. On the surface the result may appear the same as what stoicism purports to give you, but there's a radical difference. Where stoicism aims for thought-driven control, mystics know there's none to be found and instead encourage to trust in and to reconnect with our intuitive nature. Allow pain, feel it fully, let it go, and return in the flow.

If you're not into mysticism, but are interested in this kind of work for the practical purpose of navigating your experience of life with less suffering, here's a secular curriculum: start with some embodiment practice (contemplation in bodily sensations, yoga nidra, body scan meditations, soft butter meditations, Tai Chi, Qigong, any physical activity done with heightened awareness of the body), find a good teacher or therapist to guide you into Shadow Work, supplement with regular Trauma and Tension Release Exercises (TRE), sprinkle some Loving Kindness meditations to take things to another level. Do this and you won't just look the part, you'll feel it to your core.
Show HN: Titan – a distributed orchestrator with dynamically mutable DAGs
by ramnarayanan747 | 2026-01-13 17:51:15+00:00
Hello HN,

I built Titan, a distributed orchestrator, to explore the core primitives of distributed systems (scheduling, concurrency, failure detection, and IPC) without the complexity of Kubernetes or the overhead of HTTP.

I originally built it for my home-lab to orchestrate a mix of long-running services and batch jobs. Static schedulers worked at first, but as workflows grew more complex, I needed the system to adapt its execution plan based on runtime data, not just follow a predefined DAG.

This led me to evolve Titan from a hybrid scheduler into a runtime where execution graphs can be constructed or modified dynamically. It still supports static YAML DAGs, but now exposes a Python SDK that allows user code to:

Construct dynamic DAGs programmatically

Branch or loop execution based on live signals

Spawn new tasks/infrastructure in response to failures (Agentic patterns)

The core engine is written in Java 17 using raw TCP sockets and a custom binary protocol (no HTTP, no external DB, around 90KB JAR). Workers use push-based discovery and application-level auto-scaling by spawning ephemeral JVM processes when saturated.

This is a research project (no Raft or mTLS yet), but building it from first principles was interesting. I later realized I had independently converged on patterns similar to Nomad (scheduling) and Temporal (workflow semantics).

I’d love feedback on the architecture, specifically:

Runtime graph mutation as a scheduling primitive

Push-based worker discovery (vs standard pulling)

Tradeoffs of application-level scaling vs centralized autoscalers.

from https://www.nytimes.com/2025/10/15/world/europe/london-polic...

A record 80,000 phones were stolen in the city last year [inferred to be 2024], according to the police, giving London an undesirable reputation as a European capital for the crime.

Overall crime in London has fallen in recent years, but phone theft is disproportionately high, representing about 70 percent of thefts last year. And it has risen sharply: The 80,000 phone thefts last year were a stark increase from the 64,000 in 2023, the police told a parliamentary committee in June.

That is partly because this crime is both “very lucrative” and “lower risk” than car theft or drug dealing, Cmdr. Andrew Featherstone, the police officer leading the effort to tackle phone theft, told a news conference. Thieves can make up to £300 (about $400) per device — more than triple the national minimum wage for a day’s work.

And they know they are unlikely to be caught. Police data shows about 106,000 phones were reported stolen in London from March 2024 to February 2025. Only 495 people were charged or were given a police caution, meaning they admitted to an offense.

It was quite common in the wake of McVeigh and other large vehicle attacks that they should be seen as weapons and licensing strengthened.

The fact you can drive a 26,000 lb GVWR truck without any special license is something special we have in America compared to most of say, Europe. It's actually pretty mind blowing anyone can just rent 26 ft diesel 26,000 lb truck and get in and drive it on the highway.

It is testament to the fact there are a few vestiges of freedom left in America. Not much, but a few vestiges, since such trucks were around before the regulation hysteria of the late 20th century and 21st century.

> Most of the murders (homicides) in the USA are committed using illegal weapons

Hardly relevant. If you control guns better, you get fewer illegal weapons as well. Most of the murders in Europe are committed by illegal weapons as well.

> Banning legal weapons wouldn't reduce crime

Of course it would - see the reduction in gun violence in countries where this has been implemented.

> Besides, USA is not a good example. According to Wikipedia [1], high murder rate statistics in the USA are skewed due to the overrepresentation of one specific part of the population

Oh. You're one of those.

It's a peculiarly American thing to try first to look to race to try to understand something, when there are more salient correlations.

Presumably since Black Americans are overrepresented as victims of gun violence, you'd like to see a significantly higher proportion carrying guns?

Richard Bach in his book Illusions: Adventures of a Reluctant Messiah: “The bond that links your true family is not one of blood, but of respect and joy in each other's life. Rarely do members of one family grow up under the same roof.”

I first read those words many years ago. They were a comfort and a revelation then, and they still resonate today, when I have very much chosen my own family.

There is a mix of culture and food at play here. Most people, left to their own devices, without cultural pressure, are lazy, unproductive, and slovenly.

We can see that with food: as soon as the shaming of people for being fat weakened, as it happened primarily in the US and then in the Western world at large, people started to indulge without guardrails.

We can see that with clothing and appearance: people started to dress slovenly, preferring comfort to being presentable and well-put together.

We can see that with "productivity": people started doomscrolling for hours or watching hours upon hours of life lived by other people, instead of living their lives.

I think there's a big difference between the following:

- enjoying the work of an unrepentant bigot who died hundreds of years ago, whose work is in the public domain, who does not materially benefit from your spectatorship (what with them being dead and all)

- enjoying the work of an unrepentant bigot who is alive today, whose work they have ownership of, who materially benefits from your spectatorship

- enjoying the work of an unrepentant bigot who died mere minutes ago, whose work is owned by their estate, whose heirs materially benefit from your spectatorship

I think the first category is fine, the second category is unambiguously not fine, and the third category is ambiguous, but I would err on the side of "don't consume".

A little out of date now but:

> As of June 2024, Nio had installed 2,432 power swap stations in China, including 804 along highways, representing the largest battery swapping network in the country. Nio aims to expand to 4,000 stations globally by 2025. By February 2025, Nio had 3,106 battery swap stations in China, with 964 located along highways. In January 2025 alone, Nio added 111 swap stations and provided 2,949,969 battery swap services, averaging 95,160 daily.

We have neither the money (see national debt) nor production capacity (see 155mm shells, missile production, howitzer barrels, etc) to give billions away for somebody else’s war.

Furthermore, the weapons had a cost when they were new, and replacing them now carries a higher cost.

Saying the price tag is fictional is like saying my dinner is free because the steak was already in my fridge.

I think there are ways around this, you can always request a separate internet line in your work area, or slap a firewall between your space and their worklan, turning your workspace essentially into a lab. I mean we could probably take a look at pen testing scenarios, I'm sure you don't limit pentesters to your tools when they come into your workplace right? I wouldn't limit a high cost consultant with my tools. I think the reason companies provide a computer, is more for the benefit of the corporation, we want all code, iterations, and notes left behind, it's our product he/she worked on, how do we know all material was handed in otherwise? It's a very neat way to package all deliverables at the finish line.

> I've viewed and read an interminable number of interviews with Cummings.

The statements you have made don't really with the interviews I've listened to.

Your interpretation of events from reading this and previous comments is seems to omit context around key events that happened.

> He decided that a) Brexit was a good idea (we can see how that turned out)

Without re-litigating everything. It may have been different if the politicians and those that worked for them hadn't frustrated the process. I was genuinely disgusted by the attitudes that many of the politicians had after the Leave won.

It also says nothing about the validity of his other statements, which is what I was referring to.

> b) he decided to help get a Johnson government elected

Yes, but the way you are framing it comes off as ignorant of events both before and after the 2019 General Election.

Theresa May had been ousted by the Conservative Leadership after disastrous. She ran an awful election campaign and had to form a coalition Government with the DUP.

He said he was contacted by Johnson because Johnson had a minority government and couldn't call a re-election. His first job was to get Johnson out of that Quagmire, then prepare for re-election. He decided to help Johnson under certain guarantees / conditions. Which tells me that he didn't actually trust Johnson.

He claims to have been forced out by Carrie Johnson and his team shortly after the election. His statements about Carrie Johnson's involvement line up with other accounts from other people and it happened during the same time period.

So there is no reason to believe he is lying, back tracking or retconning events.

> c) joined his administration as de facto chief of staff and chief advisor. If that's not a tacit approval of Johnson and his government, then what is? Of course, he backtracked later when it was a disaster.

It not about it being an approval or disapproval of his government. Often you must work with people that you would rather not to, to achieve things.

His feelings about the Johnson government doesn't change his the validity of his statements about how Whitehall operates.

His comments about ossified organisations lines up with my past experience of working in both ossified Public and Private orgs. His account of the events around COVID match up with the timeline of events, and I re-watched old interviews of him and he hasn't backtracked at all or changed his story around what happened. He has mentioned things he couldn't mention at the time e.g. his residence was broken into and he was advised not to mention this at the time.

I have no reason to not believe him.

I think your dislike of Cummins and the Leave result is clouding your judgement on the validity of his statements about how Boris Joshson behaved and how Whitehall operated.
Show HN: Data from a mixed-brand LiFePO₄ battery bank
by wkcollis1 | 2026-01-13 17:53:06+00:00
Hi HN —
I’m sharing an empirical, long-term dataset from a DIY energy-storage project that ended up testing a common assumption in battery design.

Conventional advice says never mix battery brands. That guidance is well-founded for series strings, but there’s surprisingly little data on purely parallel configurations.

I built a 12 V, 500 Ah LiFePO₄ battery bank (1S5P) using mixed-brand cells and instrumented it for continuous monitoring over 73+ days, including high-frequency voltage sampling. The goal was to see whether cell-level differences actually manifest over time in a parallel topology.

What the data shows

No progressive voltage divergence across the observation period

Voltage spread remained within ~10–15 mV

Measured Peukert exponent ≈ 1.00

Thermal effects were small relative to instrumentation noise

In practice, the parallel architecture appears to force electrical convergence when interconnect resistance is low. I’ve been referring to this as “architectural immunity” — the idea that topology can dominate cell-level mismatch under specific conditions.

This is not a recommendation to mix batteries casually, and it’s not a safety guarantee. It’s an attempt to replace folklore with measurements and to define the boundary conditions where this does or does not hold.

Everything is public:

Raw CSV data

Analysis scripts

Full PDF report

Replication protocol

Repo:
https://github.com/wkcollis1-eng/Lifepo4-Battery-Banks

I’m posting this to invite critique — especially around failure modes, instrumentation limits, or cases where this model would break down (e.g., higher C-rates, aging asymmetry, thermal gradients, different chemistries).

Happy to answer technical questions.

As a side note, I've gotten my dad into dirtbiking for the first time at 65.

He has padded shorts, and padding pants, and a padded shirt. He then wears my track leathers, even though he's on dirt. He's fallen a few times and he agrees you feel like superman.

He's started joking that if he makes it to 75, he's going to start wearing the padded shorts and shirt as regular daily wear.

It's been awhile 2017ish, but I used to book flights for a team of photographers that traveled a lot. They all had their individual preferences for aisle/window, exit row. Maybe it was because they all had lots of butt-in-chair miles, but their upgrades were typically $25 for domestic US travel. Maybe I'm conflating that as the price for everyone when it was the price for their status only???

"What's wrong with this tho?"

The thing that is wrong about it is that the purity spiral may get out of control and result in wholesale purging of art, Iconoclast-style (or perhaps Cultural Revolution-style).

I don't trust people with an instinct to purge history. They rarely know when to stop.

Plus, standards change a lot. Picasso had a teenage mistress. It wasn't as scandalous back then. Should we really be so arrogant as to push our current standards on the entire humanity that once was? If yes, we will be obliterated by the next generation that applies the same logic to us, only with a different set of taboos.

There's also issues when the watched are funding the watches. If the council funds the newspaper, then the newspaper reports badly on the council, then the council can reducing funding for the newspaper.

You need it to be independent, so how can you fund it. Perhaps a separate precept on the council tax bill which is set separately (say by national government)

The BBC funding model attempts to do this at a national level, but of course nowadays that's not sustainable - part of the failure of the old civic minded establishment in favour of the new edgy profit minded establishment

What's lacking authenticity is your assertion a well informed political cult engaged in gaming the system for its own benefit is not working multiple narratives.

If it was just about China they would not be turning TikTok, CBS into right wing platforms. They would not be announcing intent to violate 4th Amendment and go door to door without warrants.

Trump doesn't actually care about China. He prays on idiots fears with xenophobia. Trump is Palpatine. He's afraid of losing power. See also Steve Bannon at CPAC going on about how, if Dems win midterms a lot of them are going to prison.

They need to make moves to also protect their troops: https://www.thedailybeast.com/dhs-ice-hated-under-donald-tru...

You can make all the moral judgments you like, but the fact is: They're making money either way, and then spending that money in their local communities. They can spend that money (and pay taxes on it) in the US or not.

It's no different economically than a musician or an actor doing the same.

My local issue of interest is how my county and state administer elections. I volunteer as a poll worker for nearly every election, with a preference for the "boring" low-turnout contests like state legislative and local board primaries. This experience has given me insight you would never get on national news but lots of people blindly argue about: voter ID requirements, how provisional ballots work, why higher-population counties take longer to report results on election night, what election night "calls" actually mean, entirely mundane failure modes that can slow down the line, etc.

You'd think that for such an important issue like elections you'd get more interest at the local level where regular citizens can actually get involved. But nope. We're always desperate to fill poll worker assigments on non-presidential years, even though those are the best and least stressful opportunities to experience first-hand what it's all about.

>Trump will be gone in 3 years. Maybe fewer depending on his health.

He incited an insurrection last time he had power, in a desperate attempt to stay in power. Congress impeached him for it, but spineless Republicans refused to convict him for it. Then when he got power again, he pardoned everyone who took part in the insurrection. He's talked about having a 3rd term, so if you think he's just going to go away at the end of this term, you are mistaken.

I am looking for technical solutions to establish resilient, long-term communication channels that can bypass such shutdowns. What are the most viable options for peer-to-peer messaging, mesh networks, or satellite-based solutions that don't rely on local ISP infrastructure?
