>> Please leave me alone and if someone uses a throttle bike in an illegal manner give them a ticket.

Well in most jurisidictions just the throttle is an "illegal manner", and if you're riding technical trails because of it I have no sympathy for your condition or improved quality of life; you're screwing it up for the rest of us. Maybe you should be the one who leaves.

>I always start a convo with a question, " what is exciting in your life?"

Sadly, nothing. Stuck on 2 part time jobs, I see more layoffs than job posts, I'm about to be soft evicted from my current dwelling, and my country decided to start yet another needless war.

That question works in good times in a high trust society. Now it just reminds you how little there is to look forward to.

Bullshit. That's internet incel horseshit. Have an actual conversation. Get to a point where your sole, entire intention isn't just to con a woman into sleeping with you, and where you like, maybe want to get to know her. Lose the weird, internet pick-up artist intensity.

Like, do random men you talk to think you're a creep? If they do, then maybe it's time to get some life coaching. If not, maybe, just maybe, there's some subtle differences in how you approach people you see as sex toys vs. people you see as, you know, people.

Proving policy controls are in place and that actions were taken is a fairly universal problem.

Cryptography doesn't really do as much to improve it as one would think. Yes, providing evidence of sequence or that stuff happened before a certain time is a helpful tool to have in the toolbox.

The earliest human writings date to about 3000-3500 BCE, and are almost entirely ledgers on clay tablets.

I want to point out a little asymmetry. It's a little rude to generate a bunch of stuff, including writing, using LLMs, and then expect actual humans to interact with it. If it wasn't your time to do and understand and say, why should it be worth others' time to read and respond to it?

That makes some sense. But one can make the argument given how easy it is to create CLI tools and add new API endpoints, enhancing them is still a better approach than creating and MCP.

I'm not pro or anti-MCP myself. I just haven't had a lot of success using them yet. I've been struggling to find the right balance and every path has lead me to a CLI tool (optionally paired with a skill).

Now I'm not using my cli tools in Claude Chat proper, but I'm not using MCPs either because they just keep failing me. This could very well be a me problem, but I'm still looking for that "ah-ha" moment.

Maybe I'm misunderstanding you, but the way you describe MCP sure sounds like it's just another RPC endpoint. Those are easy to add using traditional methods. Why deal with all the overhead of MCP for those cases?

Author does not know what they're talking about.

> In other words, XML tags have not only a special place at inference level but also during training

Their cited source has 0 proof of that. It's just like python/C/html in training. Doesn't mean it's special. And no, you don't need to format your prompts as python code just because of that.

> In truth, it does not matter that these tags are XML. Other models use ad hoc delimiters (as explained in a previous article; example: 
 and 
) and Claude could have done the same. What matters is what these tags represent.

Those strings are just representations of special tokens in models for EOS. What does it have to do with anything this article pretends to know about?

Please don't post such intellectual trash on here :')

Claude analysis of the article:

The author is making an interesting philosophical argument — that XML tags in Claude function as metalinguistic delimiters analogous to quotation marks in natural language, formulaic speech markers in Homer, or recognition sequences in DNA.

The core thesis is about first-order vs. second-order expression boundaries, which is a legitimate linguistic/information-theory concept.
But to your actual question — do they understand what tokens are?

No, not in the technical sense you're pointing at. The article conflates two very different things:

1. Tokenizer-level special tokens — things like 
, 
, 
 etc. These are literal entries in the vocabulary with dedicated token IDs. They're not "learned" through training in the same way — they're hardcoded into the tokenizer and have special roles in the attention mechanism during training. They exist at a fundamentally different layer than XML tags in prompt text.

2. XML tags as structured text within the input — these are just regular tokens (<, instructions, >) that Claude learned to attend to during RLHF/training because Anthropic's training data and system prompts heavily use them. They're effective because of training distribution, not because they occupy some special place in the tokenizer.

The author notices that other models use 
 style delimiters and says Claude "could have done the same" but chose XML instead. That's a category error. Claude also has special tokens at the tokenizer level — XML tags in prompts are a completely separate mechanism operating at a different abstraction layer.

The philosophical observation about delimiter necessity in communication systems is fine on its own. But grafting it onto a misunderstanding of how tokenization and model architecture actually work weakens the argument. They're essentially pattern-matching on surface-level similarities (both use angle brackets!) without understanding the underlying mechanics.

Have your agent do red/green TDD - its like double entry accounting, the tests and code mirror each other and the tests are an executable repository of docs of how the thing should behave, that helps immensely when you need to be an archaeologist and understand some deep corner of the system.

Code reviews are a cinch because if you get confused by the real code you can switch to reviewing the tests and vice versa.

These are fun but as long as it’s OpenSCAD it will always be a hobbyist toy and not able to be used for professional use. Which is fine! But imo an openscad rendering pipeline is pretty easy. I’m more interested in someone trying to take a stab at vibe coding models that output Brep compatible formats and generate STEP files. This is much, much harder to do but is the main step towards doing this for actual professional use cases.

Presumably someone is getting closer to this, curious who the most robust player in that space is.

Also curious if building an actual kernel replacement for open cascade is on the table now with AI, it’s a very tough thing to do but now it seems somewhat tractable in 2026

Wow. It’s scary to think this person votes.

A dude makes a series of terrible decisions. Decides to not learn from any them. Then blames society. Okay.

But my early story is eerily similar to his. Expect instead of just my dad dropping out to do drug, so did my mom. I grew up constantly moving between women’s shelters, random peoples couches and storage units.

And while he was in rural Oregon, I was in rural Idaho.

I ditched my parents as soon as I could. I worked basic non-silicon valley tech jobs. Moved from help desk ticket closer to actual IT career. No college, no money or time for it. Did alright.

Yeah life would have been a fuckton easier if I had supportive parents. But I’m in a good place and what I did wasn’t magic or luck. It was simply get basic job. Get shit apartment. Get slightly better job. Repeat.

This dude is deep in incel territory, which you can tell from the incel words he drops throughout his rant.

This dude says he never expected or needed any hand outs but several paragraphs earlier was complaining that the food bank didn’t provide vegan food. Ooohhh Kay. I have a lot of thoughts about both those statements. But dang dude. Maybe if you’re starving you should take any food you can get and deal with the rich people virtue signaling once you can afford to eat.

(To clarify on the above, being vegan is fucking great. It’s good to not kill animals… but you gotta take care of yourself before you take care of a cow.)

Yeah parts of the system are screw up. Yeah some people get a really unfair hand. But this guy was in generally good health, should have had health insurance through these crap jobs he was complaining about for his skateboard thing. (Which is another wtf that shows total lack of risk analysis. Who choses skateboarding as a hobby when you can’t afford a doctor. Jeez. Take up running.)

I’m wrapping up a 4 month stint at a fancy hotel working as a valet attendant. My job responsibilities as written were parking cars and helping with bags, but the unspoken expectation was that I also greet everyone who passed by my desk. These conversations are all low stakes but make such a difference in my day, and I think the article hits it on the head when they say it doesn’t have to be groundbreaking to be beneficial. The hard part is going to be continuing the habit when I’m not getting paid for it.
by josephg | 2026-03-02 02:18:20+00:00
Yeah this is the way. You will lightly bother some people by being talkative. But it’s ok. So long as you’re sensitive to their desire not to talk, you’ll be fine. Nobody will murder you in the night or kick you out of the village.

I live in an apartment (condo). I’ve been practicing making small talk with people in the elevator. The conversations aren’t all winners. Lots of people are closed off or don’t want to chat. But no matter. Elevator conversations are disposable. And most people are genuinely lovely. It’s a fun challenge trying to brighten the days of strangers.

Human effort just isn't worth very much. The strongest humans on earth can manage about 400W for an hour. Even very small ebike motors are usually capable of 500w continuous/forever, so long as the motor does not spend too much time stalled or at very low speeds.

For a normal human, a "legal" 250w motor is easily doubling or tripling their normal power output, so hauling around an extra 20kg on top of the existing ~100kg body + bike is not a big deal.

Sharing a project that I contributed to:

RunWatch is a CI/CD monitoring and analytics platform focused on pipeline visibility, starting with GitHub Actions and GitLab. Those open sourced reporter actions are my contribution and other platforms like CircleCI and BitBucket are in the works.

It's especially useful for:
- Pipeline and job duration trends
- Failure/flaky pattern visibility
- Alerts for failures and slowdowns
- One dashboard across platforms/repos/orgs

Since there are still the typical go-live rough edges the first month is 100% free with code: LAUNCHMONTH

Would love feedback either in comments or here: https://runwatch.io/contact

Presumably this hypothesis is meant to explain why there is this observed asymmetry in the type of Neanderthal DNA we find in modern human populations that contain them, which is entirely autosomal. With none in the mitochondrial form, which is exclusively passed down along the female line, and also none in the Y-chromosome form, which is exclusively passed down along the male line.

Without weighing on the validity of their hypothesis that one or both sides found the other“especially attractive”, an alternative mechanism that could explain why we only see Neanderthal autosomal DNA in modern humans could be that only the female offspring of male-Neanderthal and female-sapiens pairings were reproductively fertile. This is more commonly the case in interspecies hybrids, see Haldane’s rule.
by levocardia | 2026-03-02 02:19:41+00:00
One of the ML textbooks (ESL maybe?) I read described decision trees as (paraphrasing) "really great - they are interpretable, fast to fit, work on lots of different types of data and outcomes, insensitive to scaling and distributional issues, don't have too many tuning parameters...except they just don't work very well." That latter problem can be solved with bagging or boosting, though you are bargaining away many of the other advantages.
by Qwertious | 2026-03-02 02:19:59+00:00
Fixed for metric:

>Class A: Bikes that can not go over 10mph (16km/h) via a throttle. And can’t go over 28mph (45km/h) with pedal assist. Or set the pedal assist limit at 20mph (32km/h) if you’re feeling especially conservative.

In Australia, the pedal-assist limit is 25km/h (~15.5mph). And frankly, that's plenty.
by butcloudagent | 2026-03-02 02:21:14+00:00
Okay, MCP is useless if the agent has full CLI access, sure. But what if it's a remote cloud agent connecting to another equally remote service. Well, now I need to install said CLI tool. What if I dont want to install a local mcp server either (which was always a stupid idea), and I want for there to be an harness around what the agent can do instead of give it a whole API?

With that said, the total number of applications that should have a MCP before an API is 0, and all that go beyond that threshold are partaking in sin and sacrilege.

I don't think older British lady is in the cards for me but I get your point. One of my friends has a dog (a very cute little yorkie) who I take on walks fairly often. Let me tell you: I get so many people coming up to me wanting to talk when I'm out walking that dog. It's like I'm suddenly transported to a different universe where people are 100x more sociable.

It makes sense: people love dogs. It gives us something in common and is a starting point for conversation. And people with cute dogs seem much less threatening.

But I also kind of resent it. I wish people would want to talk to me when I'm just me.

>Get to a point where your sole, entire intention isn't just to con a woman into sleeping with you, and where you like, maybe want to get to know her.

But the point of this exercise isn't to make a deep friendship. It's practice. Is this article inherently creepy?

>Like, do random men you talk to think you're a creep? If they do, then maybe it's time to get some life coaching.

If they do, they're a lot better at hiding it. The big difference is in threat level. I don't see men nor women approach me and think "are they trying to hurt me/hit on me" as a default.
by skeeter2020 | 2026-03-02 02:22:20+00:00
again, you're confusing/conflating the definition of ebike. The problem is not a senior or disabled person using a pedal assist bike; it's electronic motorcycles being ridden like they're bicycles, by underage, inexperienced kids without protection. This is going to turn out much worse for everybody; look what New Jersey has done for ALL ebikes because of the lack of understanding that there is a big difference between a pedal-assist mountain bike and an electronic motorcycle.

>> Starting January 20, 2026, all e-bike riders in New Jersey need three things: a license, registration, and insurance. You have until July 19, 2026 to get these sorted out.

I think the most important problem here is that this is an ambulance not a monster truck. It never ceases to amaze me how people on this site will always insist that the onus should be on society to deal the fallout from silicon valley's poorly-tested and poorly-designed bullshit. In a truly just world we'd be able to charge Google's leadership as an accessory to homicide for this.

"as much as" implies that it's not going to be truly sight unseen and that that is going to be what granny's perfectly maintained home will get.

Randomly, I looked up the US state capitals (since I live in one) for market appreciation, or depreciation. My state is in the top ten, still seeing >3% YoY appreciation as of last month.

I mean just as a counterpoint:

I am a Junior dev (graduated in 2022) and I am gainfully employed at the McGowan institute, earning an okay salary, with colleagues who actively use LLMs, but there is zero talk of firing me or laying me off due of LLMs. I personally avoid LLMs for most things other than:

1) Google search which actually works
2) translating MATLAB, which I have never learned (and probably won't ever)

There is a whole team of Junior devs, and actually on Friday I got an email asking if I could refer another junior/entry level. Granted it was for a 1 year contract, but still.

I really do not get this hype.
by diacritical | 2026-03-02 02:24:14+00:00
I'm not a dualist or anything. I'm in the "it's weird and I have no idea what the answer is" camp. And yes, I've read Dennett. I'm trying to understand your views. Lots of questions follow, but don't feel like I'm barraging you unnecessarily. Just trying to figure out your view with what seem to me like interesting questions that I myself can't really answer.

I'm using "consciousness", "subjective experiences", "senses" and "qualia" as synonyms here, but if you see a difference, please mention it. Obviously "consciousness" has many definitions that have nothing to do with the "hard problem of consciousness", so I'm using it in this sense here. I'll use "qualia" as it's the word that relates most to the hard problem of consciousness. You can substitute it with "sense"/"senses" if you like.

1. Do you view qualia as an emergent property? Of what exactly? What is a self-modeling system? Is a human one? Where would the boundaries be; would they even be defined? The human body or the brain only or the nervous system? Or whatever neurons activate when a certain thing happens, like seeing blue or feeling pain? What about animals - pigs, dogs, rats, snails, ants, bacteria? What about AI, current and theoretical?

2. Could there be a set of minimal self-modelling systems in some abstract space that are the boundary of what has qualia and what doesn't? Like, these 1000000 neurons arranged like that qualify, but if you take 1 out, they don't? Or is it a fuzzy boundary somehow?

3. What kind of statements could be made about the qualia of yourself and of others? Not sure what kind of answer I'm looking for, but how objective or truthful would those statements be? Maybe "qualia is nothing really, we only have the set of equations that govern physics and everything else is an abstraction"? Like an apple isn't anything really, it's just a badly defined set of atoms and energy. There is no "apple" or "chair". Or is it something else?

4. What are your views on meta-ethics and ethics in general? Should we care about it at all?

the alternative should be using a real statically-typed language instead of glorified comments that don't do anything without outside tools.

I understand that very large code bases have been built in python and this is a compromise to avoid making them rewrite Ks upon Ks of LoC but as it stands, Python type annotations are akin to putting a Phillip's head screwdriver on a ball peen hammer; the screwdriver is not a real screwdriver and the ergonomics of the hammer have been compromised.
by ActorNightly | 2026-03-02 02:24:34+00:00
Lets be clear, you and most people aren't "fighting". Typing comments on the internet, voting, and maybe donating money to PACs is literally the minimum amount of effort anyone can do to show support.

Even for those that are doing political outreach, while the effort being put in is more than the average person, the direction is misplaced - in 2024 it was pretty clear that no matter how much information you give people, they are going to vote a certain way because of extreme polarization.

If people were willing to actually FIGHT for what they believe in through offensive means, physical or cyber, with direct results, I would have a different opinion.

But at this point, its pretty clear where society is headed. I don't want to live in that world either, but shit is going to boil over at one point or another, and delaying the inevitable just means we all get fucked when we are senior citizens instead of within the next decade.

Lasting consequences include social outcasting and even dismissal. Those are pretty lasting.

>Just don’t make things a big deal

That sadly doesn't stop the runmors from flowing. That's the real damning thing about such social faux pas. Your reputation can be ruined without having a single person say it to your face. That's both unsettling and morbid for how you look to humanity.

I think this one is a bit different, faster/easier to input and an information dense display.

I'm a software engineer with 25 years of experience, and this started as something I built for myself. I originally wanted to track energy and didn’t find something in the App Store that fit what I had in mind. I prototyped the first version in Rork, which got me moving fast, then migrated to Xcode when I needed more control over proprietary extensions.I’ve been using it daily for several months while I add features and rearrange things. I’m just starting to promote it now.

The main screen shows your whole week at a glance as a color grid, so you can spot patterns without navigating through multiple screens. Data stays private on your device and backs up to your personal iCloud. No sign-in, no shared database. All of the important features are free and there are no ads. There is a subscription for some extra features.

Feedback and bug reports welcome! I’m hoping some others will find it as useful as I do.

Cheaper, quieter, smaller footprint for storage, can be easily brought up a few stairs or put in the back of your car (by one person), slower (a perceived safety advantage by some, as most motorcycles can go highway speed), maintenance is less daunting (again, perceived), culture (perceived) as some people are quite turned off by motorcycle culture, and many many more.

The only place MCP made sense for me, so I thought, was to give my Claude Web agents access to the same cli tools my Claude Code agents had. In this context, agents don't have shells.

However, then I discovered MCP servers on Claude Web are forced onto my laptop for Claude Code, which is very confusing. I don't know if there is a way to stop that, but it has messed up my Claude Code agents.

Is this experience common, and is there a known way to stop this?

So sure... and so wrong. I've done government contracting. If you angered the Pentagon enough they would simply blacklist you. You couldn't get a contract or be a part of someone else's contract.

The difference with Anthropic is it's open and above board instead of the customer telling a company "You can't sub with those guys or you won't get the contract."
