From the article, Table 3: 100% SoC @ 25°C leaves only 80% of the original capacity after a year.

It's easy to look at that table and think that it's remaining charge after a year; it's not. It's lost capacity.

This is known in the industry as "calendar aging". So far as I know, stockpiles of lithium ion batteries are stored at a relatively low state of charge and in a cold environment for this reason among others. It's common to order a laptop battery or similar and get a unit that was manufactured a year back. It would be terrible to get a new battery that already had diminished capacity, which is what would happen if you stored them in a non-conditioned warehouse in a hot climate.

I wrote my story and titled it, "My experience at work with an automated HR system". I sent it to a few friends, only a couple of them read it.

A week later, I renamed it to "The Machine Fired Me". That seemed to capture it better. The goal wasn't to make it click bait, but it was to put the spoiler, and punch line right up front. It blew up!

I had just read Life of Pi, and one thing I like about that book is that you know the punch line before you even pick up a copy. A boy is stuck with a bengal tiger in a boat. Now that the punch line is out of the way, the story has time to unfold and be interesting in its own merit. That's what I was trying to recreate with my own story.

This reminds me of my former college who asked me to check some code from a study, which I did not know it was published, and told him I hope he did not write it since it likely produced the wrong results. They claimed some process was too complicated to do because it was post O(2^n) in complexity, decided to do some major simplification of the problem, and took that as the truth in their answer. End result was the original algorithm was just quadratic, not worse, given the data set was easily doable in minutes at best (and not days as claimed) and the end result did not support their conclusions one tiny bit.

Our conclusion was to never trust psychology majors with computer code. And like with any other expertise field they should have shown their idea and/or code to some CS majors at the very least before publishing.

The killings are horrifying in their own right, but the most disturbing part to me is how quickly the Trump administration will just declare these people as "terrorists" before any kind of investigation has happened.

This suggests to me there is some level of systemic intent (or at least ambivalence) with this administration's use of ICE's use of lethal force. It is beyond concerning. This admin is now very literally murdering us and will immediately try to justify it.

I agree with your first assertion but not so much on the rest. There is more than one reason to write and for many it is about communication, they have something they want to express and you would be wise to consider your reader if that is your goal.

Hooking the reader with the opening page is swinging to the other fence of having a terrible opening page that no one will get through, generally not good to swing to the fences. I think the writer should be honest and upfront with the reader, the opening pages should be representative of what is to come, they should represent the whole and not just the beginning.

The thing also is, it doesn't matter what the truth is. If the computer says you did a thing, the thugs (ICE) will do what they want.

Here is someone out for a walk, ICE demanding ID, that she answer questions. She says she's a US citizen ... they keep asking her questions and one of the ICE people seem to be using a phone to scan her face:

https://np.reddit.com/r/Minneapolis/comments/1qbawlr/minneap...

What she says, the truth, none of it would matter if his phone said to bring her in. And after the fact? The folks supporting ICE have made it clear they've no problem with lying in the face of the obvious.

I'm afraid of the day strongmen come into power in my country and start targeting people on their social media history. I'm sure to end on _some sort_ of naughty list. You kind of get how people become depoliticized and apathetic when resistance has no apparent effect and speaking up only gets you in trouble. That's how civic societies atrophy and die.

Wall Street has also increasingly pivoted to hiring strategy roles and operating via India [0].

Roles like Valuation Specialists, Credit Modelling, and M&A advisory that just 10 years ago would have been core strategic roles with in-person requirements in NYC have now shifted East and service both the NAM and EMEA markets.

Pretty sure it destroys something in you as well. So many context changes with no relation whatsoever and regular hooks that give you a pinch.

We haven't evolved for that. Our brain is trying to figure out a narrative between two things following each other. It needs time to process stuff. And there is so much shock it can absorb at once. So many "?!" and open loops in a day.

I made a TikTok account to at least know what people were talking about. After 3 months, I got it.

And I deleted it.

I felt noticeably worse when using it, in a way that nothing bad for me, including the news, refined sugar and pron, ever made me feel. The destruction was more intense, more structural. I could feel it gnarling.

In a way, such fast feedback is good, because it makes it easy to stop, while I'm still eating tons of refined sugar.

There are absolutely people in this group who woke up hoping they got an excuse to murder someone. You interact with the entire gamut of human experience every day, but you never know which ones are the secret heroes and which ones are the secret concentration camp guards until they're presented with the right set of circumstances. It's as much a mistake to assume that everyone is relatively moral as it is to assume that everyone is relatively evil.

Sure, you can batch. But that means your decrements must be _entirely_ buffered, right? Because you cannot remove anything from the main filter until you know its count is zero, and you don't know its count until you've processed all increments. And you need to do that under a lock, or you'll have a race where you could have a false negative in the main filter for a short while.

Here's EU telling Microsoft how to conduct business globally, back in 2004 - https://economictimes.indiatimes.com/news/international/ms-s... - 'help rivals connect their products to the Windows operating system.' does not mean 'EU rivals', but any 'rivals', outside of the EU as well.

'Intel v Commission (C-413/14 P, 2017)' is another case where EU Antitrust explicitly punished global conduct outside of the EU.

Right now, with exception of antitrust, EU laws only incidentally affect global conduct, e.g. once a business is compliant with GDPR, it's often too costly to restrict compliance just to the EU.
Nothing stops that from changing. EU absolutely can make a law that obliges e.g. chat app providers to either apply EU privacy standards globally or face bans/fines/seizure of their EU operations.
Show HN: Helping my band rehearse remotely without installing a DAW
by vaneyckseme | 2026-01-25 20:55:03+00:00
Hey everyone,

I built an app called SingTogether because I was tired of trying to get my bandmates to install complex DAWs just to practice over a demo. I wanted something that works instantly in the browser.

It’s designed to help bands and choirs practice and collaborate using their own multitracks.

The Main Use Cases:

1. Rehearsing a Song

The Problem: Sending MP3s back and forth is messy, and you can't isolate instruments.

The Solution: The band leader uploads multitracks to the app and sends a link. The team opens it (on phone or desktop) and can practice using standard tools like solo, mute, pan, and volume faders to isolate their specific part.

2. Asynchronous Jamming

The Problem: We want to experiment with ideas but can't meet up.

The Solution: A band member adds a base track (instrumental or vocal). They send the invite link, and other members can record a vocal or instrumental part straight from the browser. Everyone can listen to the layered contributions immediately.

I'd love for you to try it out and let me know what features would make your practice sessions easier.

You know I’ve never read an article by Gwern that made me feel like he was sensitive to this idea, one that in my head essentially breaks down to the use of narrative and the leverage of “stakes” that inform the reader of kinds of conflict that make a narrative special.

I’m reminded of a remark made by David Foster Wallace (on KCRW? Or oft-repeated elsewhere) about how he had to come to terms with the purpose of writing not being to show off how smart you are to the reader. Instead your writing has to evince some kind of innate investment to the reader that piques their genuine interests and intrigue.

A lot of writers are tainted by the expectations set in grade school. Write for a grade and good writing is what yields a good grade according to the standards set by the subject which often is not ‘Composition’ but more like ‘Prove to me that you remember everything we mentioned in class about the French Revolution’.

I’ve never felt drawn into an article by Gwern at least not in the way that I have been by some writing by Maciej Cegłowski, for example. Reading Gwern I am both overwhelmed by the adornments to the text (hyperlinks, pop-ups, margin notes; other hypertext doodads and portals) and underwhelmed by the substance of the text itself. I don’t consider Paul Graham a literary griot either. But I find that his own prose is bolstered by a kind of clarity and asceticism that is informative and not entirely void of good style and form.

Lawrence McEnery of the University of the Chicago contributed a lot of good thinking to this kind of stuff though.

This wasn’t meant to be a criticism of the author of this post’s own work. But here that’s how it’s left. I haven’t come across any writing of his that’s as intriguing as "Empires Without Farms: The Case of Venice” seems. If anyone has any recommendations, do share.

No, the way any serious person would look at crime data is per capita. You take the number of crimes committed by an immigrant and divide by the number of immigrants. That gives you a rate. The rate is lower than for people born in the US.

This may be the first time you are exposed to this idea, because you have been lied to repeatedly that crime is high and it's immigrants doing it, but it's well studied.

I agree, but in this hypothetical situation the HR part needs to happen, despite the fact that most people don't want to be the squeaky wheel that explicitly starts pointing fingers..

It's way too easy to pretend the system is the problem while sticking your head in the sand because you don't want to solve the actual human problem.

Sure, use the post mortem to brainstorm how to prevent/detect/excise the systematic problem ("How do we make sure no one else can make the same mistake again"), but eventually you just need to deal with the repeat offender.

It really doesn't matter much. The Titan and K3 are Core 2 performance, the K1 and JH7110 are more like Pentium III.

A 1.5 GHz Ascalon is still going to be ... I don't know ... Skylake level? More than enough for a usable modern desktop machine and a huge leap over even machines we'll start to have delivered 3 or 4 months from now.

And Germany would have been a much larger country economically if Hitler was executed after his first coup attempt. The Weimar government didn't choose that path though, and went for civility.

The brain drain was massive, both before the war, and even more so after. That didn't stop the peasant minded from supporting the Nazi regime though. They got to punish the people who they were told made them poor.

I live in FL, so I get to interact daily with people who are cheering for this crackdown, and have said the equivalent of "those rioters (protestors) should be put down in the street". I don't have much hope for where our country is headed.

The flags on any type of post like this are absolutely ridiculous. Glad the mods are at least for now letting this one stand.

Just had a great experience with this on Linux. One time in 20, when my X1 Carbon (Pop OS 22) resumes from sleep, Bluetooth doesn’t work. This kinda sucks because my mouse is Bluetooth.

After 10 minutes with Gemini, we found the incantation to completely reset the USB+HID stack. I put the commands in a script, and I could make the script auto-run on wake if I wanted.

I was so happy. Even after 8 years on Linux I didn’t expect this to work.

I'd totally use a memory safe browser even if it made all the C++ code 4x slower. Execution time of C++ code is far from a bottleneck in the perceived speed of a web browser these days. I guess the main downside would be the lack of a JIT for JavaScript. Would it ever be possible to extend Fil-C's safety guarantees to a JIT compiler? I'm not sure how that would work.

If you are debating whether to read this article, read it. It’s comprehensive and precise, and although political in substance, not political in form — test-fitting an imprecise definition. The fact it also reaches a firm conclusion (spoiler alert right there in the title) is depoliticized by allowing for malleable application. A benchmark article I will now go share elsewhere.

What’s left to talk about? How to react. How it ends. Where we likely go from there. Where we should go.

Short answer: Japan treats high-speed rail as a tightly controlled system, not just fast trains on tracks.

One major difference is infrastructure. Shinkansen lines are completely separate from conventional rail: no level crossings, no shared tracks, no freight, and no interaction with slower services. There are no cars, pedestrians, or animals anywhere near the line. In much of Europe, including Spain, high-speed lines are very good, but they still tend to interact more with legacy rail networks and inherit more constraints.

Another key factor is how strictly operations are controlled. Speed limits are enforced automatically rather than relying on driver compliance alone. If a train exceeds its permitted speed for any reason, the system intervenes immediately. The design assumption is that human error will happen, so the system is built to prevent a mistake from turning into an accident.

Maintenance is also handled with extreme conservatism. Track geometry, overhead lines, and rolling stock are continuously monitored, with very tight tolerances. Components are replaced earlier than strictly necessary because preventing failures is considered far cheaper than dealing with the consequences of one.

Japan has also invested heavily in detecting external hazards. Earthquake early-warning systems automatically cut power and apply brakes before shaking reaches the tracks, and the same mindset applies to weather, landslides, and other environmental risks.

Finally, there’s a strong institutional safety culture behind all of this. Procedures, training, and reporting of near-misses are taken very seriously, and lessons are applied incrementally over decades. The objective isn’t just to meet safety standards but to systematically remove edge cases.

It’s not a single piece of technology that explains the record. It’s the combination of dedicated infrastructure, automation, conservative engineering, obsessive maintenance, and a culture with very little tolerance for shortcuts.

> Rather final ultimate authority needs to be distributed amongst the states. The unrest in Minnesota would be solved in a week if the governor could simply use the National Guard to restore law and order without worrying that the out of control federal executive would just take control of them

We tried that with the Articles of Confederation. Then half the country tried it again 70 years later. It didn’t work out either time.

Trump’s not even close to the worse President we’ve had. He’s just the craziest since television became widespread. FDR who is widely considered one of our best Presidents put nearly 100k US citizens of Japanese descent in interment camps.

You can't get a packet from a random store wifi network to your home network when your home network is using 192.168.* (barring something like routing headers, which most routers wouldn't process). You said that yourself in the first part of your post, and I don't think I ever argued otherwise.

> Symmetric NAT 100% stops inbound unsolicited connections to the public IP

No, it doesn't. If it did it wouldn't be possible for routers to accidentally make their web admin or UPnP interfaces available to the Internet.

It doesn't stop connections to your router, and it doesn't stop connections through your router either. It just plain doesn't stop connections, which is why it protects you from 0% of attackers.

> They probably don't wake up thinking "Today I'm going to murder someone" but they just don't realize what they're doing.

Jonathan Ross (the ICE agent who shot and killed Renée Good) is an Iraq war veteran who has served in military and paramilitary units (National Guard, CBP, ICE) for over two decades. He intentionally engaged in a behavior that has been documented as far back as 2014 [1] to manufacture a reason to shoot the person in front of him.

Did he premeditate killing someone while getting out of bed that morning? Probably not.

Did he make the decision to kill Ms. Good in advance? No reasonable doubt.

> Good for a phone, certainly.

The multiple lenses and the processing power make smartphones wildly better than almost any consumer camera, particularly for someone without professional photography skills. A professional camera in the hands of a professional photographer can do better, but that means the market has changed from "consumers buy consumer cameras, professionals buy professional cameras" to "consumers use the camera that's always in their pocket and get surprisingly good results, professionals buy professional cameras".

This is common advice in English classes and it predates the World Wide Web (and likely the Internet).

Hook them in the first few sentences or lose them.

Everyone's paying a lot of attention to how bad Trump is, or the midterms. My question is, what happens in 2028? How much of current policy is something the majority of Republican voters (let alone the American people) or the political class actually want and would do without Trump to lead them? How much is only being implemented due to Trump's choices, political style and cult of personality? (Assuming Constitutional safeguards remain strong enough that Trump can't find a way to remain in power past his current term; if Trump is still President in 2029, the system's seriously broken down and all bets are off.)

Will the US say "Wait a minute, things went too far, now that he's gone we need more checks and balances before another President tries to repeat what just happened" like when they added term limits to the Constitution after FDR, or some of the post-Watergate limits imposed on the Presidency?

Or will Trump's redefinition of government power become normalized, like the redefinition of government power that happened with the Patriot Act, TSA security theater, NSA spying on US citizens, etc. after 9/11 that was justified as anti-terrorism? Those policies were never unwound even though the wars in Afghanistan and Iraq are over, Osama bin Laden is dead, and there have been no more attacks on that scale.

>> serious threat

> Regardless, neither that agent's actions nor his decision-making were serious

This is a strange, non-sequitur word game.

> They're also "allowed" to get out the damn way.

I previously submitted a legal analysis (https://www.youtube.com/watch?v=bDda-L_ZOE8). Please indicate where you disagree with what is said in the video. The short version is that what the officer could have done, with the benefit of hindsight, is not legally relevant.

Note that I have not insulted you at any point, nor alleged bad faith on your part, so I think this is a more reasonable request than the one that was made of me in the other thread.

> But they are allowed [to murder because they feel like it]

No, my entire point is that this is objectively not covered by the definition of the word "murder", and that it was clearly not done "because the officer felt like it".

> Interesting how the violent solution seems preferred, though. One might even mistake a "law enforcement officer" for a "gang member".

This sort of rhetoric is not conducive to discussion.
