Have you actually lost weight like that? I think exercise is a huge trap for weight loss. Cardio exercise makes you healthy, but it will also make you hungry. Especially if you are not used to it. Overweight people are usually already overeating. They can't deal with hunger and cravings well. If you make them do cardio, they will likely eat back whatever they burned and most likely much more. And even if they don't, they were already overeating, so chances are high you are not in a caloric deficit still. I have lost a lot of weight (30kg) three times now (gained some of it back every time unfortunately) and I think there is much truth to "You don’t lose weight at the gym, you lose weight in the kitchen.".

Thanks for your feedback — I really appreciate it. I agree with you that the headline and description didn’t address the needs well. I’ve already updated them right away. Do you think they’re better now?

Regarding the video, I did include the steps and some screenshots of the PDF generation process. That said, I agree it’s a bit too long, even for a tutorial. I didn’t polish it further or make it more compact earlier due to time constraints. I’ll consider creating a better one later.

Thanks again!

> in a healthy amount

That's the crux! Constant hunger starts nagging me as soon as I try. I've tried several times for several months, with nice results from the weight's points of view, but I never got to the point where my quality of life globally increased, and that was always due to the constant hunger.

I'll only retry when I'll have found a way to stop the hunger now.

TL;DR

- K2-18b

- detected dimethyl sulfide and dimethyl disulfide, false positive possibility is now very low

- "produced by marine-dwelling organisms on Earth", possibility they were produced by other processes (unrelated to life as we know it) not high but maybe unknown unknowns

- other factors like distance from the star are in favor of life & water

- previous studies detected methane and carbon dioxide

One pretty easy way to do it while running your own DNS is to put the zone files, or some input that you can build to zone files, in version control.

There are lots of systems that allow you to set rules for what is required to merge a PR, so if you want "the tests pass, it's a TXT record, the author is whitelisted to change that record" or something, it's very achievable

10k calories a day is what a black bear eats preparing for hibernation. And it is what Michael Phelps would eat daily when training in the pool for hours on end.

Obese people can remain obese eating 1000 calories a day. I recall one episode of My 600lb Life and the show's featured person that day was at 900 or 1200 calories a day and still didn't lose weight. Might have still been gaining.

It is a dynamic system. People tend to only consider the CI in CI/CO.

I think AI can and will replace many stakeholder-facing SWE eventually. It's not there yet but I don't see why it can't reach there. On the other hand, it needs very good integration and a complete revamp of human workflow to adapt to AI (hint: a lot easier than making AIs that adapt humans). Even if AI never replaces some roles, the increased productivity means that less humans are needed. The next consulting wave is FAANG pushes internal teams to integrate with AI and then these teams leave to consult other companies in AI integration to get big $$$.

I work as a data engineer, and I'm pretty sure that the current AI is good enough to do around at least 50% of my work. I look around and believe the same applies to my data analyst colleagues as well.

I believe stakeholder-facing engineers are the first to get hit, like data engineers and frontend developers. The reasons are:

- In general their work isn't very technical (it can be, but not common) and often repetitive. There are tons of examples and documentation online.

- They face business stakeholders directly. The communication is not always smooth, so the stakeholders have the incentive to train themselves talking to AI trying to get things done ASAP.

it's never about the trade war

NVDA reached its peak after the release of DeepSeek‑r1, and, more importantly, the entire AI industry is extremely overpriced

Thanks for your question! While the previous project focused mainly on general AI photo transformation, this one specifically specializes in creating collectible-style anime, Barbie, and action figures from photos.

Also, we've improved the model outputs and added more figure styles based on early feedback. It's part of an ongoing effort to explore creative AI personalization tools.

Appreciate you checking it out!

At Polars I developed a new query engine which uses a hybrid of push and pull. I gave a short (and not very technical) talk about the engine at our first meetup recently, which can be viewed here: https://www.youtube.com/watch?v=Ndil-eLynh4.

Each operator is a (set of) async functions which are connected to its input(s) and output(s) through capacity-1 spsc async channels. An operator pulls input by reading from a channel, and pushes output by writing into a channel. For an oversimplified example, consider a simple select operator:

while let Ok(morsel) = input.recv().await { let result = select(morsel); if output.send(result).await.is_err() { break; } }

Note how it has two await points: on receive and send. The nice part about this is that Rust will automatically transform these asynchronous functions to state machines which can pause execution when either a send or receive blocks, returning control to our scheduler. In the above example the operator is able to pause both to wait for more data, or to wait until the receiver is able to consume more data. This also makes for example pausing execution in the middle of a hash join probe to send some partial results onwards in the computational graph trivial.

You wouldn't necessarily need to keep track of all states that have been visited before, to my understanding, just one extra state that you move along at half the speed (so it'll eventually also enter the loop, and then the state you're progressing at full speed will loop around and hit it). So 2X the memory and 1.5X the time/compute of the program on its own.

Firstly that is completely badass science. The idea that you can use observations to detect the chemical composition of an exoplanet millions of kilometres away is an absolute triumph of the work of thousands of people over hundreds of years. Really amazing and deeply humbling to me.

Secondly, my prior was always that life existed outside of earth. It just seems so unlikely that we are somehow that special. If life developed here I always felt it overwhelmingly likely that it developed elsewhere too given how incredibly unfathomably vast the universe is.

You missed a very important detail, the language runtime.

While Haskell's runtime is designed for Haskell needs, Clojure has to be happy with whatever JVM designers considered relevant for Java the language, the same on the other platforms targeted by Clojure.

This is yet another example of a platform being designed for a language, and being a guest language on a platform.

How is that possible? There is a lower bound on calories needed (on average across say six months) to maintain life. Adding to that the calories needed to maintain the weight, I don't see how an obese person could stay alive with "CO" significantly lower than 1200 kcal.

But then the ip-poachers wait for you at the gates. Investing into the new thing, in a world order where copying the new thing is the best game approach, makes R&D a looser strategy. You need temporary punishment tariffs on products that steal IPs to recuperate the investments and make it a bad strategy - or else..

Patents do not work - because the rule of law does not exists without the international order and goverments have a tendency to trade away such cases for protection of big players.

That's not an accurate description.

For example, it is common in sorting algorithms to do an n² algorithm like bubble sort when the list to sort is small (e.g. <50), whereas when it's larger, we do an n log n algorithm like merge sort.

The issue is that merge sort does recursion, which comes with some extra cost, so that an n² algorithm beats an n log n algorithm, provided n is small.

It has nothing with your criticism to do.

Since the rise of LLMs, the thought has definitely occurred to me that perhaps our intelligence might also arise from language processing. It might be.

The big difference between us and LLMs, however, is that we grow up in the real world, where some things really are true, and others really are false, and where truths are really useful to convey information, and falsehoods usually aren't (except truths reported to others may be inconvenient and unwelcome, so we learn to recognize that and learn to lie). LLMs, however, know only text. Immense amounts of text, without any way to test or experience whether it's actually true or false, without any access to a real world to relate it to.

It's entirely possible that the only way to produce really human-level intelligent AI with a concept of truth, is to train them while having them grow up in the real world in a robot body over a period of 20 years. And that would really restrict the scalability of AI.

Navidrome's killer feature is its simplicity, and not just the dead simplicity of setting it up: Jellyfin has everything and the kitchen sink, which is nice - especially for video, whereas Navidrome offers a well-honed, long matured, music search/browse/play standard API, namely Subsonic which opens a world of clients for a multitude of platforms and all tastes... On that front Jellyfin feels narrow in comparison.

Maybe the amount is record-breaking (but then it's probably "just" adapting to what's possible) but fundraising dinner events with the President at $10k+ a plate are standard in US politics.

In this case I think it's because it's not just a dinner where you may see the President from far away, it's a smaller setting where you may be able to speak to him.

Legally this is a fundraiser for political campaigning with none of the money going to the President. Again, I believe that this is standard in the US.

In the EU subsidies for infrastructure upgrades are tied to a minimum, non guaranteed, downlink speed of 30 Mbps. For a family it is enough for most normal uses.

ISPs perhaps decided it was commercially more convenient, for the industry at large, to cross subsidize demanding applications by providing everyone with gigabit class connections and CPEs.

Actually that thread has an interesting theory:

"... o-series models are often prompted with previous messages without having access to the relevant reasoning. When asked questions that rely on their internal reasoning for previous steps, they must then come up with a plausible explanation for their behavior."

The fact is that humans do this all the time too -- their subconscious prompts them to do something, which they then do without reflecting or analyzing what their motivation might be. When challenged on it, they come up with a rationalization, not an actual reflected explanation.

The movie "Memento" is basically about how humans do this -- use faulty memories to rationalize stories for ourselves. At some point, a secondary character asks the main character, "And this fancy suit you're wearing, this car, where did they come from?" The main character (who is unable to form any long term memory) says, "I'm an insurance agent; my wife had insurance and I used the money from the payout to buy them." To which the secondary character says, "An in your grief, you went out and bought a Jaguar."

Not to give any spoilers, but that's not where the Jaguar came from, and the secondary character knows that.

Claude Code has outstanding performance in code understanding and web page generation stability, thanks to its deep context modeling and architecture-aware mechanism, especially when dealing with legacy systems, it can accurately restore component relationships. Although Codex CLI (o4-mini) is open source and responsive, its hallucination problems in complex architectures may be related to the compression strategy of the sparse expert hybrid architecture and the training goal of prioritizing generation speed. OpenAI is optimizing Codex CLI by integrating the context control capabilities of Windsurf IDE, and plans to introduce a hybrid inference pipeline in the o3-pro version to reduce the hallucination rate.

Whether it's actually correct, whether it works, I don't think that's even a concept in these systems.

I'm not an expert, but it is a concept in these systems. Check out some videos on Deepseek's R1 paper. In particular there's a lot they did to incentivize the chain-of-thought reasoning process towards correct answers in "coding, mathematics, science, and logic reasoning" during reinforcement learning. I presume basically all the state of the art CoT reasoning models have some similar "correct and useful reasoning" portion in their RL tuning. This explains why models are getting better at math and code, but not as much at creative writing. As I understand it, everybody is pretty data limited, but it's much easier to generate synthetic training data where there is a right answer than it is to make good synthetic creative writing. It's also much easier to check that the model is answering those problems correctly during training, rather than waiting for human feedback via RLHF.

It seems that OpenAI forgot to make sure their critic model punished o3 for being wrong it claimed it had a laptop, lol.

I shared it on the catlang discord, Devine immediately replied "wow, that looks so much like uxn 0_o" hahaha. It's not the most active server but the response has been very positive! A few people thought it would probably be fun to use it to build a custom IR as part of a compiler pipeline, that was the context of the question.

I personally really love the utf8 and the "z80 for loop" examples, those are beautiful and make me nostalgic for the days I was writing stuff for the TI-83+ in Z80 assembly.

> The observations also provided a tentative hint of dimethyl sulfide (DMS), a possible biosignature gas, but the inference was of low statistical significance.

From the source paper. It is a very important result but not definitive, false positive is still possible as well as us finding a new way in which DMS can form without a biological process.

Still freaking exciting and fantastic scientific achievement. JWST is already bearing incredible fruits.

Projects and performance come out of practice and training. Each attempt was repeated and refined until it matched their inner style [1].

And they never gave up until then.

Sure, it gets boring. Mix it up; be silly; take breaks. Try a different perspective; teach others.

Sometimes it only makes sense with age.

I mean, the ranges of a European mentioning that they are overweight compared to the US are of course very different. What is overweight here counts as normal over there.

I am currently at around ~120kg and my "goal weight" was around that area. I still have a tummy that I am not satisfied with, but my legs are mostly muscles due to me cycling a lot. I sold my car on purpose to force me to cycle in bad weather.

Currently I am also trying out a more hardcore exercise program because I never gained a lot of muscles in the past, even when I was doing MMA training 6 times a week.

I'm probably stating the obvious here: muscles weigh more than fat, meaning you'll always gain weight before you can lose weight. I mentioned the 2-3 months time span because that's (for me) when it switched, and my body suddenly had it easier to get into calories burning mode.

Suffice it to say: I don't eat nor drink any sweets, not even in my muesli. No artificial sweeteners either. I replaced sweets with fruits in my muesli, for example. And I just drink water, because soft drinks are the human brain's enemy.

The decision to not eat nor drink anything sweet is important, I think, because it helps me go into calories burning mode much faster with much less calories.

> Know/practice rucking with 50kg for a 20km brisk walk (maintain speed 7-8 km/h) on uneven terrain, and no water (speak to your doctor first)

Ermm..... This is so far beyond basic militarytraining. Did you mean 5kg? And no water? There are special forces units that wouldn't be able to do this.

Full kit loadout is like 20 kilos, maybe 25-30 if you are the LMG/Nlaw carrier in your unit.

>Fast for 3-4 days (just to see what it feels like)(speak to your doctor first)

>Thirst for 1-2 days (just to see what it feels like)(speak to your doctor first)

No water for 2 days is MUCH worse than no food for 4.

The conclusion of the article is flawed.

The article could have been a nice recollection of a battle with a wonderful, long-lasting effect, yet unknown to most people - generally speaking, I mean... you'll surely have studied it if you grow up in the countries around the Alps.

But the conclusion is useless and wrong:

> the international order that diplomats have painstakingly built

Diplomats did not build anything, apart for those cases where the peoples had already decided they didn't want to go to war with one another.

In every other situation, it was the military R&D that shaped the current world order. Putin, Jong-un, and Khamenei still ruling their countries, while Gaddafi and Saddam are no more, does not let any chance of being misinterpreted: is you have nuclear weapons, you can be an a**; if you don't have them, you can only choose between complying with civil manners or being obliterated.

> false positive possibility is now very low

It's not that low, unfortunately. From the article:

> They say their observations have reached the ‘three-sigma’ level of statistical significance. This means there's a 0.3% probability the detection occurred by chance. And to reach the accepted level that would mean scientific discovery, observations would have to meet the five-sigma threshold. In other words, there would need to be below a 0.00006% probability they occurred by chance.

To ensure the AI doesn't hallucinate bad responses, focus on the following steps:

Quality Training Data: Train the model on high-quality, up-to-date company documents, ensuring it reflects accurate information.

Fine-tuning: Regularly fine-tune the model on specific support use cases and real customer interactions.

Feedback Loops: Implement a system for human oversight where support agents can review and correct the AI's responses.

Context Awareness: Design the system to ask clarifying questions if uncertain, avoiding direct false information.

Monitoring: Continuously monitor and evaluate the AI’s performance to catch and address any issues promptly.

You say:

> specs in line with what I see on dell.com as still available in new systems

But I'm not sure if you mean the relative performance of an entry-level chip like the N100 or the raw numbers like "6-8 core, 3.8GHz" - the performance may be fine for your use-cases but doesn't actually compare to decade-newer chips like M2 when pushed.

> Are you saying that, it deliberately lied to you?

Pretty much yeah. Now “deliberately” does imply some kind of agency or even consciousness which I don’t believe these models have, its probably the result of overfitting, reward hacking or some other issues from training it, but the end result is that the model straight up misleads you knowingly (as in - the thinking trace is aware of the fact it doesn’t know the answer but it provides it anyways).

> The surprising thing here is that people think that LLMs are "powerful at solving math tasks".

That's not really surprising either. We have evolved to recognize ourselves in our environment. We recognize faces and emotions in power outlets and lawn chairs. Recognizing intelligence in the outputs of LLMs is less surprising than that. But the fact that we recognize intelligence in LLMs implies intelligence in them just about as much as your power outlet is happy or sad because it looks that way to you.
