News for hackers. Stuff that matters.

Yes, making it effectively disposable.
Yes it does. It's the "51.2V Vertical Battery Pack" with the 314 Ah EVE cells. I have two of them connected in parallel, communicating with my Sol-Ark 18k inverter via a standard Pylontech protocol for closed-loop communication. Maybe I confused you by describing it as a "wall mount"? The vertical batteries are very often wall mounted. I should have just said "vertical" instead. Anyway, they have been fantastic batteries. Two in parallel can discharge roughly 19kW of power continuously, which is more than enough to power all of the big loads in my home at the same time. The only downside of the batteries is you have to configure the JK BMS yourself. But there's a lot of community resources for that: https://docs.google.com/spreadsheets/d/1szaRxYzBHxwairtpCBBF...
Many of them are not constructed for repair and have a lot of integrated components. It's an era of disposable cars so to speak.

With some notable exceptions, I would argue that most of the time, the caller simply doesn't care. Maybe the "right" approach is to provide two functions, one that takes an allocator, and one that does not. That way the caller doesn't have to care unless it wants to.
I have two Yixiang power 16kwh wallmount batteries ($2200 each). The 32kwh battery is $3699. They work remarkably well and have EVE LFP cells and a JK bms. They are not UL listed, so keep that in mind. My system uses a more expensive SolArk 18k inverter, and these two batteries easily power my whole house through the night, even this time of year. It's not enough to be off grid 100% of the time, but where I live, it's probably close to 80% of the time.
You can get a 32kwh battery for about $3500. 12kw in solar panels is about $2500. And an inverter is a couple thousand. Throw in since mounting equipment and wiring, and a big system that can power a 4000 sqft home can be had for around $10k. If you want it truly off grid, you'll want a bigger battery and more panels to make it through consecutive cloudy days.

Unfortunately for me, yes. Some companies are very risk adverse and would rather stick with the devil they know. They have no idea what they are sacrificing.

That's why I installed my 13kw system myself. I saved a ton of money, assuming you don't equate time with money, otherwise it will have cost me a fortune. It was a great learning experience, and quite fun.

Re:Toyota is finally taking its best-seller electric on Thursday September 24, 2026 @09:56PM (#49839353)
I'm not super concerned about green energy, but i put solar panels on my roof and charge an ev because it's incredibly practical and a much better experience than the status quo.
Re:Toyota is finally taking its best-seller electric on Thursday September 24, 2026 @09:53PM (#49839333)
The aesthetic has nothing to do with it being an EV. They just designed it to be ugly.
Re:Toyota is finally taking its best-seller electric on Thursday September 24, 2026 @09:49PM (#49839300)
Neglecting a cabin air filter isn't going to make your EV fall apart. You can neglect that on an ICE too. Imagine how much worse these people would have it with an ICE vehicle - neglecting oil changes, oil filter, brake fluid, radiator coolant, air intake filter, spark plugs, valve cover gasket, power steering fluid, putting the wrong gas in, topping off with the wrong oil, etc...

I think this is awesome! LAN parties were so much fun back in the day. And the social aspect is what I miss the most (and my youthful energy to stay up all night).
Re:Fine, I'll build my own text editor on Wednesday September 02, 2026 @01:13AM (#49532006)
I use emacs daily (with vim keybindings of course), but I completely understand why vscode is so popular. It's extremely easy to get started with, has features galore, and sane defaults. Emacs takes much more effort to get productive with, although this is improving with each release.

Yes, as bloated as Go. I consider Java, C# and Go roughly equivalent in speed, space, and memory.
Re:I spent twenty years becoming good at the wrong game on Thursday August 20, 2026 @10:54AM (#49375500)
While I agree with you, I also have to acknowledge the absurdity of some schools having kids define their own crazy undergrad majors, while plunging them into large amounts of debt. They should at least have to sign a waiver that says, "I acknowledge that this degree will likely not be a good investment".
Re:Emacs 31.1 RC1 is available on Monday August 17, 2026 @10:46PM (#49340604)
I'm a life long vim user, and I love Emacs w/evil mode. There's something about hacking in elisp on the editor that you're using to do the hacking, that just makes me fall in love with programming again. I'm not joking when I say this, but one of the activities I look forward to when I'm retired is hacking on Emacs.

Thanks to those who continue to make these Emacs releases happen.

I think they believe that AI will account for nearly all production, and jobs will no longer be necessary. At the very least, it's going to be tumultuous.
Re:Abdominal fat predicts heart disease risk better than BMI on Saturday August 15, 2026 @08:51PM (#49315762)
I haven't been down in the normal BMI range since 8th grade. And I was measured at 6% body fat my senior year in high school! BMI has always run several points high for me. For that reason, I've always liked waist to height ratio better.
Re:Jolt: Clojure compiler implemented with Chez Scheme on Tuesday August 11, 2026 @09:43PM (#49266906)
I think the author has been very open about the use of LLMs. And while I am very wary of LLM slop, this is one use case where it makes complete sense to utilize them to the fullest. A Clojure implementation already exists for LLMs to reference, and tons of test cases to verify behavior. It doesn't get better than that for LLM usage.

> If you're good you can keep a lid on tech debt in the face of rapidly changing requirements. If you suck at it, well... you can't.

Every drop of tech debt (aside from AI slop) I have ever been a part of has manifested simply because some manager or executive made the decision to sacrifice quality for short-term speed. Sometimes this looks like an unskilled developers producing something that management won't let you fix. Sometimes it's a completely unrealistic deadline that requires extreme measures to meet. If you are able to keep a lid on tech debug in the face of rapidly changing requirements, it likely means that you have enough slack in your job to do so.

If you're using Lisp, then sure. If you're using C++, then chances are you're going to have to heavily overengineer the thing to cover all possible requirement changes. That comes at a great cost - in most cases, you are unlikely to benefit from the overly abstract design, but you will pay for that additional complexity for the life of the project. I am convinced that you are better off designing the project to solve the problem in front of you, and then if the requirements shift, pay the cost to solve the new problem, rather than forever pay the cost of solving a host of unrealized problems.
Re:I'm 38 and I Can't Support Myself Anymore on Tuesday July 28, 2026 @06:12PM (#49090658)
People say this, but I'm not sure I understand how it could be true. For example, taxing billionaires is often cited as the solution to this problem. But if we took Elon Musk's $730 billion fortune and divided it evenly among the US population, people would receive a one-time payment of about $2000, and then that fortune would be gone, and any opportunities or advancements it was creating. So I'm genuinely curious where you see this incredible excess coming from.

Do you feel threatened that Russia and Iran will succeed in conquering all of Europe and the Middle East? I see it more like a couple of misbehaving misfits. That's very different than say, WWII.
Re:Claude Opus 5 on Saturday July 25, 2026 @08:34AM (#49047084)
One could argue that human learning is not all that different from machines training on data. We are all regurgitation our own experiences and knowledge to some degree. We certainly have things that machines don't, but LLMs can definitely come up with novel things that were not in the training data.
