I paid an average of $0.31 per kWh last month with SCE (which is on the low side, because a lot of that is charging my car, which I have setup to only charge during off-peak). I see under $0.06 per kWh of Non Bypassable Charges. The word "tax" does not appear on the bill, except in a notice about raising rates which mentions a loss (with the word "after-tax" appended to the amount of the loss) incurred by SCE.
I didn't talk about it in the article, but my strategy is:

1. Local time machine backup (for disk failure recovery)

2. All the Docker container mount in a particular directory, and I periodically sync that directory to an S3 bucket

3. Planning to have Backblaze for more disaster recovery

All of these would have downtime in the event of an issue, but that's ok with me.

If these symptoms were not attributable to covid, we would expect that the symptoms would be present at the same rate in patients who have never had covid, no?

I'm also not sure what the explanation would be for why the symptoms improve over time, if those were the causes.
i generally consider myself an enemy of psychedelic advocates, because I think they want to make it effectively socially mandatory to do these drugs, which is really bad.

("sure, it's your choice what you put in your body, but a really enlightened person wouldn't be so frightened and closed-minded that they don't want to see what psychedelics can show them...")

of course ketamine for depression has this giant downside risk of adverse effects and psychosis, and we should talk about it more, not just sell it as a safe miracle drug.

however... safe, neutral, bland, boring well-tolerated SSRIs, also have a massive downside risk, in that they can trigger a manic episode, which in severe cases also involves psychosis.

so i find myself in the position of being glad there are different depression treatments for different people, including psychedelics and dissociatives, and hopefully we can find a way to make sure people get sorted to the treatments where they are least exposed to the tail risk side effects.
There's a difference between "you personally can't pay to insure it" and "it is not possible to insure". By your definition, a lot of very cheap cars are "uninsurable" because their owners are broke, which does not seem to be a useful definition.

I work with a couple workloads that can’t even be completely deployed in cloud environments. Those aren’t common.

The vast majority of companies can get along with a Google office license and a Wix website.

Not everyone works at a company with hundreds of thousands of employees and hundreds of millions of users.

I agree RDS, Aurora, Big Query, S3, load balancers, declarative security policies, artifact repositories, managed auto-scaling clusters and so on are very convenient, but they aren’t a requirement.
hey Mozillians (:
That’s not universally true
Have to hard agree on this.

Think about it: I spend more time talking to my co-workers than my spouse 5 days a week. Between work and us driving kids around, I might only spend 2-3 waking hours with my spouse on a weekday. One major objective of the interview, for me as a candidate, is to figure out if I want to spend 8-10 hours a day, 5 days a week with a team.
The extraterritorial effect of the law is profoundly troubling, especially the prohibition on revealing the existence of the Technical Capability Notice. However, Apple would almost certainly be subject to lawsuits in the US and EU if it secretly added a backdoor to iCloud Advanced Data Protection, because doing so would violate their privacy policy and would likely give rise to fraud claims. They could kill iCloud Advanced Data Protection entirely, or they could add a backdoor and say there is a backdoor, but they could not, without being exposed to liability, secretly add a backdoor while simultaneously claiming that the data is end-to-end encrypted and nobody other than the user can access the data.

It is not that DC has more losses. it is that transforming DC voltage is non-trivial. With AC you just need a couple of magnetically coupled inductors, no moving parts, easy to build, efficient, reliable. With DC this does not work, you need to convert it to AC first do the transform then convert it back. Nowdays we can achieve pretty good efficiency doing this with modern semiconducting switches. But historically you needed to use something like a motor-generator and the efficiency losses were enough that just transmitting in ac was the clear winner.

The losses over distance thing is the fundamental conflict between desired properties. For transmission you want as high a voltage as possible, but high voltage is both very dangerous and tricky to contain. So for residential use you want a much lower voltage. we picked ~ 200 volts as fit for purpose for this task. but 200 volts has high loses during long distance transmit. So having a way to transform the current into voltage is critical.

Some of our highest voltage most efficient long distance transmission lines are DC, but this is only possible due to modern semiconducting switches.

Show HN: Torchhd – A Python Library for Hyperdimensional Computing
Hyperdimensional Computing (HDC), also known as Vector Symbolic Architectures, is an alternative computing paradigm inspired by how the brain processes information. Instead of traditional numeric computation, HDC operates on high-dimensional vectors (called hypervectors), enabling fast and noise-robust learning, often without backpropagation.

Torchhd is a library for HDC, built on top of PyTorch. It provides an easy-to-use, modular framework for researchers and developers to experiment with HDC models and applications, while leveraging GPU acceleration. Torchhd aims to make prototyping and scaling HDC algorithms effortless.

A fun threat to read for the current hype cycle.

You can tell who is working in the field by the fact they don't use VLMs for OCR and who isn't because they think it's a solved problem.

A question to the authors.

Do you have resources to train any VLMs from scratch? They aren't quite the bests the sota LLMs are and I think they can be made a lot more useful with:

1). Better training data.

2). Larger vision parts of the model.

In short: 2d attention is not something that anyone's doing at scale - that I know of - and is a no brainer for understanding images.
DMA is very popular among EU voters.
My favorite example of this is Pete Hegseth. The fact that a man with zero qualifications, experience, or demonstrated aptitude to run an organization with 3.4 million employees and an $850 billion annual budget can go on and rail about how "woke hiring" allows unqualified people to rise to positions of prominence in government just shows that some people are completely incapable of shame or introspection.

> We've landed on a hybrid approach of reviewing a small homework exercise they were sent prior in an interview and find it a lot more useful to ask them to explain their approach and use it as a jumping off point for other questions. When's the right and wrong place to use arr.reduce()? Why did they need event.preventDefault() in that form submit handler?

I applied this approach recently and it was... depressingly useful. Sent out 3 short tasks which should take an experienced programmer less than 30 minutes to solve in total: one "find, fix, and explain the problem in this code" and two "write the ~50 LOC to implement these exact specifications". These went out only to those whose resumes looked like a potential fit.

Something like half of the responses we got back didn't even compile/run. Mostly due to hallucinated library functions.

One candidate had decent responses, so we went on to the full interview, asking (as you mentioned) if he could explain his approach. He was having some trouble so I just asked him to explain how a sync.WaitGroup (which he'd used in his code) actually functions, and we got treated to an intensely painful few minutes as he desperately tried to spin some BS about how important concurrency is, and how Go's so powerful at concurrency, etc etc etc. but nothing about what a WaitGroup actually does.

I don't really know how to solve this shit going forward.

> Apple/ARM platform development will continue downstream. If I feel like

I may, or I may not.

I suppose it's possible that that could turn out well.

The situation with Apple hardware feels a bit like the early days of Linux (including the fast pace of development). There was a time when if you wanted broad hardware support it was better to run an Alan Cox kernel than a Linus kernel. And the whole point of git was to have a system that didn't require one central blessed tree.
A few years ago I heard a story on NPR about someone who built a site that also used the IBM quantum backend. They had you input a question about what you should do with your life (I think the example was "Should I grow a beard?"). Then the quantum backend would give you a yes or no answer.

The idea here is that if you believe the many worlds interpretation then that quantum decision splits the universe in two, and in one universe you grow a beard, and in the other you don't.

I thought it was a fun idea.
Per a separate comment I made, I think you could add to this and call it an AI assisted code review. Not just can the user review the code shown, but can they review the code that AI creates?

Yes, AI code is sort of like any other code in that it can have errors, but I think taking it to the next step is whether they can actually modify or follow up with the prompt to get it to do the right thing.

AI is kind of like having a really smart and confident intern who's sometimes wrong or doesn't quite understand your request. But you're not a manager or a lead. You're just some junior hire who's got AI saying, "Hey I have this figured out and am very confident in my results" and it's your job to check their work.
Pivot into cybersecurity?
As a pentester, a mountain of security bugs in a mountain of AI produced slop that no one understands is the ideal provider of job security, I guess

Maybe pentesting can be partly automated, but "the devil is in the details" and a pentester's primary quality is to look where the automated software won't.

It would cost less than $50 to equip a kettle with appropriately sized battery. You only need something like 0.2 kWh of capacity.
Rust is generally safer than Zig, but unsafe Rust is/was (mid)designed in such way that it's almost guaranteed to blow in your face eventually.

I don't know if mutable noalias has been already enabled for good, but even if there are no changes between compiler versions, those mutable noalias rules are super-tricky to get right.

In Zig, a pointer is just regular thing, you take care, but most pointers are arena-allocated anyway, and that's a bit like runtime-branded lifetime (which is great and Rust cannot do that, at least not in idiomatic Rust).

Long COVID in kids is real and widespread. It’s not "rare". Far more than 200k are affected. This latest survey aligns with previous data, but it’s likely an undercount(noted by the authors as a limitation) due to reliance on parental reporting. Kids often struggle to articulate symptoms. Pediatric Long COVID has been ignored despite millions suffering debilitating effects.

Note: I work on NIH efforts to cure Long COVID called RECOVER, RECOVER-TLC, and help non-profits dedicated towards viral persistence/immune dysfunction hypotheses.

Me too. Just as most problems won't need "phd-level intelligence" (whatever they might want you to think, 10x devs don't require phd skills nor research abilities / test time compute for being good at their job), most problems won't need subsecond latency or response time.

Automated resume rejection as a service is half the reason we're in this mess.

Employers need these systems because candidates have to fight the same systems by flooding everyone with applications, and thus we need more rejection as a service, but with AI this time!

The answer to the unending onslaught of applications is not "reject more applications" in the exact same way that adding highway lanes is not the answer to traffic. You'll just get even more applications.

Great, so we all agree that according to the German law, researchers have access to this data, so there is no need to argue about it! I would personally go so far as to say "the people" at large should also have access to the data, so that no one can weaponize the definition of "researcher" or "the people" (which is prone to happen, as evidenced here), but luckily that's not the conversation we're having today, in this case the law is very clear and the German courts agreed so. Also, the GP post by that individual had no point, it was ostensibly a question, but in the article they covered that in this case, according to the law and German courts, "the people" means "researchers", so they either didn't read the article or were redirecting for other reasons. I just wasn't going to play around with their "definitionalism" where definitions of simple things are the most important talking point in order to off-track a discussion.
I once did something similar with a recipe from a cookbook where the recipe started at the bottom of one page and continued onto the next page.

Not liking this, unless FEMA has discretion to fund mitigations in advance of events, it's role is reactive. I thought the defensive works like levee construction was the army corps of engineers and the states civil construction people.

I do think defensive preparation should be done, it's almost certainly cheaper in the long run. But I'm unsure FEMA has a significant role in public education about climate change and so I can somewhat relate.

Obviously it's not being done in a benign, neutral environment. It's part of an attack on AGW as a social construct in a politically divisive time.
>Most of life’s engines run on sunlight.

There's a huge amount of life that runs on zero sunlight and instead runs on chemical energy deep in the earth. It makes up maybe 10% to 20% the biomass on earth and a good chunk of its biodiversity and is quite likely where life originated, hundreds of millions of years before photosynthesis evolved. It also quite possibly exists in a similar way on Mars.

An interesting example is D. audaxviator, which runs on uranium and is named after a passage in Jules Verne’s “Journey to the Center of the Earth.”

A lot of it has been discovered fairly recently - there's an unusually interesting nyt article on it all, including how they may transform rocks and continents https://www.nytimes.com/2024/06/24/magazine/earth-geomicrobi... or https://archive.ph/VgzKD

Appliances, like electric range, that need higher power have dedicated 240V circuits. My understanding is that 240V circuits use thicker cable because they usually also have higher current. But it is possible to convert 120V to 240V if only one device, sometimes done for imported electric kettles.
Absolutely.
