Not at all, if you have a lot of data coming from imperfect hardware (which can mean both a fixed bias and unknown variance), and you don't know the variance for plenty of practical reasons, you are left with a result that is statistically significant, but wrong

On other news, the AI company recently found to have poor cybersecurity posture, still has poor cybersecurity.

If this was a peer-reviewed paper, it won't pass.

- Is the wearable accurate enough to be sure that 3bpm is not a measurement fluke? - Why did you use the minimum heart rate value (which could be a measurement glitch) and did not compare a percentile (e.g., 2.5th lowest percentile)? - Were all assumptions for paired t-testing valid? How did you account for likely temporal correlations in the data (e.g., sauna could have an effect also on a night 2 days after it, same for exercise)? - How can you define a "comparable-intensity exercise day" if you don't know the characteristics of the sauna?

Honestly impressed! While humanoid legs are an interesting challenge from a technical point of view, there are plenty of examples in nature (roadrunners) and tech (anything with wheels) that are more efficient and practical.

Fair, I forgot about aphantasia! The whole plan for AGI is still built on creaky eugenic foundations: measuring intelligence to distinguish who is "intelligent" and who is not. The whole idea of "human baselines" from the paper is terrifying, they even start it by excluding people without a high school degree! Looking at their 10 cognitive faculties ontology, there is no reason why people with lower education levels should be excluded...

Every week we are 50% closer to shifting the goalpost...

from the paper "AI systems already possess some capabilities not found in humans, such as LiDAR perception and native image generation". I don't know about them, but I can natively generate images in my mind.

Except now we get websites that need to download 20-25MB of "latest cool framework" to show you a blurb of text because programmers before you created unnecessary complexity that needs to be maintained forever.

The honest opinion no one wants to hear is that programmers do not deserve the money they are paid for because MOST of the time what it's really needed is a "single sqlite db with a php frontend".

Dijkstra understood it 50 years ago, and again 26 years ago [1]. Nothing changes. Malpractice just propagate and there are zero incentives to build simple, small, and maintainable software. If the company you work for just push for unnecessary complexity, get out of there! Don't fold!

From the post you linked "These findings do not represent the specific environmental impact for all Gemini App text-generation prompts nor are they indicative of future performance."

I would like to see independent agencies having access to the various companies to provide reliable estimates. Just because humanity as a whole consumes a lot of water does not justify the extra consumption of water AND energy AND land AND monetary resources that is wasted on AI crap.

Their whole product is about vibe-coding unmaintainable "apps", not surprised they put the same level of (dis)attention in their blog too.

Also yikes for the proprietary modifications. AI companies: "what's yours is mine, and what's mine is mine only"

Sam Altman (and everyone else in the field) complain that estimates of water and power consumption of AI are wrong, but instead of just publishing that data they come up with this crap.

Humans also don't have wheels, but we build objects with wheels. It is as if we can build objects that don't resemble humans for specific purposes. Crazy...

Maybe because of the multiple investigations Tesla has currently due to crashes, deaths, injuries, etc. all caused by "whoops our cameras were fooled by some glare/fog and accelerated into a truck/pole"

lccerina — Thu, 19 Feb 2026 14:46:54 +0000

not OP, but sometimes I add the ebook version to my library even if I never use them. To find it again and fix it, sometimes I need to scroll through the years of read books to spot the tiny icon that distinguishes the version of the book. It would be nice to have a simple filter by book type (physical/ebook/audio) in the library page.

Everyone: things suck, better move my stuff on a small home server. The hyper-scaler mafia: NOT ON MY WATCH!

The only silver lining is that newer devices will have to scale down memory, so developers will have to ditch memory-sucking frameworks and start to optimize things again.

"Oh no, I am using a thing that no one is forcing me to use, and now I am sad".

Just don't use AI. The idea that you have ship ship ship 10X ship is an illusion and a fraud. We don't really need more software

lccerina — Thu, 08 Jan 2026 14:58:53 +0000

Not like having a portable number, but I was able to do it kinda okay with DuckDuckGo @duck mail forwarding, at least for newsletters and other semi-spammy emails.

It is used to remove trackers from emails, but then I was able to just change the forwarding from gmail to another provider and that was it.

As a limitation, it doesn't allow to respond to emails from the same @duck email.

An interesting perspective on this is why Facebook kept the Sun's microsystems sign in their Palo Alto HQ. Nothing in tech is inevitable, nothing in tech is irreplaceable, nothing in tech is permanent.

Shout out to the Juicero example, because there are so many people out there showing that AI can be also "just squeeze the bag with your hands".

New comment by lccerina in "The writing is on the wall for handwriting recognition"

lccerina — Wed, 03 Dec 2025 13:11:50 +0000

Most likely, and probably inferring the structure on texts with "similar" writing forms. Tried with my handwriting (in italian) and the performance wasn't that stellar. More annoyingly, it is still a LLM and not a "pure" OCR, so some sentences were partially rephrased with different words than the one in the text. This is crucially problematic if they would be used to transcribe historical documents
