This. This is the most important thing to consider: the available corpus the model was trained on. Remember that LLMs are inferring code. They don't "know" anything at all about its axiomatic workings. They just know what "looks right" and what "looks wrong". Agentic and RL are about to make this philosophy obsolete on grand scale, but signs still don't look good for being any to improve how much they can "hold in their head" to infer what token to spit out next from the vector embedding, tho.

But does this mean I need to keep receipts around for decades? What if a claim gets denied and dr. is dead or no longer practicing?

Has anyone tested this HSA claim approval amd reimbursement of 30/40/50 year old medical work before? Is there a chance the rules could change and the medical care has to be recent?

> Mind you, I don't really have any alternative suggestions.

This is thing.

If this choice is between:

1. A gameable system that will be gamed by most students.

2. An ungameable system that will unfairly punish those bad under pressure and time constraints.

There isn't really a choice at all.

One option would be a school-provided proctoring system, allowing teachers to outsource the actual test-taking times. It could be done outside of class time, at the student's convenience, and they could have 3-4 hours if they chose.

raku has had feed operators like this since its inception

# pipeline functional style (1..5) ==> map { $_ * 2 } ==> grep { $_ > 5 } ==> say(); # (6 8 10) # method chain OO style (1..5) .map( * * 2) .grep( * > 5) .say; # (6 8 10)

uses ==> and <== for leftward

true it is syntax sugar, but often the pipe feed is quite useful to make chaining very obvious

This was one of the most incredible essays about war I've ever read. At some points I forgot that I was even reading an essay about war, but everything came together in the end.

I think Sandlin was one of the few authors (perhaps alongside Remarque) that could adequately capture the silent resignation into fear (or 'fey' as he put it) that so many people have; my father was one of those people, and while his time at war was something I barely understand and was never told about—probably to shield me—his description of those restless nights dreaming of patrolling Okinawa (or Fallujah, Kandahar, or Kashmir) are something that truely can't be described by the language of peace, or even by people who were not there—like myself.

There's a certain melancholy in the tone of the entire essay, something that I think grips so many people in my generation (and that Sandlin mentions while describing Wagner): the belief that while life continues on as normal today, the world is about to be irreparably changed for the worse; perhaps we'll go to war with China, Russia, Iran, or some other country, but in the aftermath, everything we've taken for granted in life will be completely gone. I think an entire generation of young men now believe that they'll eventually be shipped off to some war and might not return—and if they do, just like Eugene Sledge, the entire world around them will be completely different. And eventually, no one will care to hear about their war stories and their memories of it will fade.

> But it is not like cities are walled off.

Sadly it is, once you live in another district they can and will refuse to treat you.

> If you need urgent specialist care, they have helicopters that can fly astonishingly fast.

Oh no, my comment was not about urgent care, it's just often people get appointments with specialists a year or more in the future. Or you pay out of pocket and get it much faster but again those specialists are only in big cities.

> The original comment was about moving to "a small town", not moving to "a specific small town".

Sure, and my comment is representative about small towns in Slovakia.

> but is staying in Slovakia a hard constraint?

For me currently it is, but many people are moving away.

Looking at the listed curricula, this won't teach kids the skills they need to have financial literacy which is a very low bar needed to make financial decisions.

Listed Curricula: Budgeting • Saving • Banking • Credit • Investing • Insurance • Taxes • College Finance • Career Planning • Entrepreneurship • Economics • Consumer Rights

This is so broad that the important parts won't have sufficient detail to understand the foundations. I can almost guarantee you they won't have talked about fiat currency, or inflation aside from the macro perspective which won't connect to anything at the individual level (Micro).

If you want your kids to understand finance and by extension money you start with Mises on Human Action, then The Theory of Money and Credit, then Menger/Hayek, a review of Adam Smith's 5 volume set, and later Socialism.

Here's an alternative hypothesis...

People thrive under regularity, and young people (especially) tend not to understand that. Similarly, being able to focus on a single thing is a kind of super-power, while multi-tasking generally hurts performance on tasks.

Going to class (and paying attention) means that you've got a regular period of focus on the class topic. That combination of regularity and focus translates into long-term learning and better performance.

It‘s still a bit flaky getting video acceleration (not talking about object detection but video decoding) working but after that it is one of the best solutions for live object detection I‘ve ever tried: no more small animals waking me up in the night.

P.S.: I‘m also supporting them with a yearly? subsciption to train the „A.I.“ model against false positives I provide which increased the accuracy even more.

There’s a significant amount of discussion and research about the problems both young men and women face. It’s definitely not 100% a men are to blame for everything, situation out there. There’s plenty of discussion about how women treat each other, about how some of the staunchest supporters of laws against women’s health care and autonomy are women, and about the crazy expectations for men that some (mostly young), women have.

Each topic hits only certain types of distribution, so if you’re reading and social media sources, are all pretty similar, or you aren’t trying to make sure you click / positively influence the feed to what you want it to be, you might be missing a huge swath of information.

> The first week or 2 of each semester is very light.

Please tell that to the undergrad STEM professors, please. Almost all of mine had an assignment first class that was due by the third class.

Freshman engineering is generally Calc I, Physics I, Chem I, and English Composition/Writing and often some random engineering/computer thing. I assure you that schedule sucks even harder that it looks like it sucks, and it gets more time consuming as the years progress.

While there were lots of Party Hardy(tm) types in the College of Arts, the ones I knew who were taking their degrees seriously were working every bit as hard as the STEM folks. Possibly, they were working harder as they needed a lot more extracurricular work and achievement since what they were doing didn't have nice, clean objective measures like STEM does. They spent a lot of time being unpaid labor at functions and networking like crazy.

By contrast, no matter how many hours they worked me at my summer internship, it simply never compared to the grind at school.

This is the complete opposite of how LLMs are trained. LLMs are most effectively prompted (for instruct/chat finetunes anyway, i.e. chatbots) through the same kind of language patterns (natural or formal/programming) that they learn from. Trying to write formal prompts to them is exactly as misguided as speaking to your friends and family in C.

good code may not look like you expect

- duplicate code isn't always bad

Sometimes* the same code copy/pasted or repeated is much easier to understand than pulling it all into a subroutine. It seems logical when writing code, but kills understanding when reading code. Predictable is better than compact a lot of times.

- code should fail early

Sometimes* "being robust", correcting errors or continuing after an error is the wrong thing to do. When something unexpected happens, failing, and failing quickly might be important.

- explicit is better than implicit

Sometimes* it is much better hardcode a list of things instead of constructing the list from whatever is there.

concrete example would be a makefile that compiles .c vs a makefile that compiles one.c two.c three.c. Hardcode the list. Make it hard fail if something is missing or something is added. Yeah, it is more work, but the madness it prevents is worthwhile.

there are probably thousands of these things. All are opinion, like camelcase sucks and indent should be 4, but not with tab characters.

* not always

You say “blockade” without thinking about the consequences.

The US blockades Japan causing food shortages. The military prioritizes what little food is available for themselves. The know the population will starve, but it’s necessary to defend Japan against the foreign Invaders. As long as there is enough food for the military, the war can continue.

Now you have a mass famine where millions of women and children slowly starve to death. Japan uses it for propaganda showing how cruel the West is and how if the West would just sign an armistice leaving the military junta in charge, all these people could be saved.

Is that better?

You're conflating authority, the authorization to do something, with autonomy - the ability to use that authority at your own personal discretion. The law grants a regulatory agency the authority to do something that they would not otherwise be able to do, like nationally ban widgets. But the law does not also inherently grant them to the autonomy to do so entirely at their own discretion. For agencies under the Executive branch, the President is free to direct them to utilize their authority at his discretion.

I think "rediscovered" is a bit dismissive. Upgrading software on a computer whose capabilities are akin to the state-of-the-art in the late 1990s and is 12-13 light minutes away is non-trivial. Also, no pressure because losing contact means the end of a whole team. I'm pretty sure they know a lot of things they could do but don't because the risk/reward ratio is too high... all without "rediscovering" it.

Roughly two in three Americans don't make it. Other countries may have worse odds. At least you'll have good company.

It's a cycle. Some generations enjoy life. Some will fight so that future generations can enjoy life. The best thing you can do to honor the past generations is to give future ones a chance.

As long as you set your goal to help others, you can't really fail, you'll just die trying. There's all kinds of advice that say you should take care of yourself first, but that's how we got here in the first place. Apes together strong.

Try reading more than one leftist book: Fischer is great, but he doesn't try to talk praxis. So I'm talking about pragmatics here: just pretending that "we can abolish work by automating it" is pure ideology, totally ignorant of the centuries of historical examples to the contrary. Any time you get back will immediately be seized. What matters are your personal capabilities, what the working class is capable of doing with their own hands. You advocate waiting on the bourgeoisie to hand over control (what, out of good will?), but Fischer could tell you that only by seizing power for themselves can the working class ever become free.

Did you account for leverage? I agree with you all the way, however, the top reason it can actually be beneficial to most people is the fact, that they can leverage their money.

Putting it a bit simple, it would mean, that for most people, ncr_(real estate)^t > c*r_investing^t

It all depends where in the world you are, but most places have easier access to loans for real estate than investment, and everything else being equal, the risk is also higher. There might be this line of thought in wake of the financial crisis, that real estate carries close to or as much as the same risk. It doesn't. It's just not zero, and that is the lesson learned.

That's Java's story.

A single language to rule them all: on the server, on the client, in the browser, in appliances. It truly was everywhere at some point.

Then people massively wish for something better and move to dedicated languages.

Put another way, for most shops the productivity gains and of having single languages are far from incredible, to being negatives in the most typical settings.

Maybe, women don’t have a responsibility to me to make things work. I just don’t see a world where women stop working, and go back to where they couldn’t own property or get a credit card or bank account without having a man. Women have discovered that it’s possible to find men that have jobs, take care of themselves, and participate in household chores and child rearing, and frankly the expectations in general are reasonable.

The fact that so many men have the response to that of, fine… we’ll take away your reproductive freedom, and next we’re coming for divorce. We want you trapped.

Society changes, people have to adapt, and right now society is failing men, and they aren’t adapting on their own. I’m not sure what the answer is, but Andrew Tate for sure isn’t it.

So. I teach at a university and I do give an "assignment" exactly like this.

In a few of my classes, I have final projects that teams work on. I also have presentations. I used to require them of all students; and quickly learned this is a good way to waste valuable time.

Now, all my presentations are completely optional for NO CREDIT. You don't get penalized if you don't do them, and perhaps more importantly, I give ZERO EXTRA CREDIT for doing them.

As you can imagine, every single presentation I've gotten from this has been absolutely worth it.

you definitely came ahead by not buying and you did the math. Good for you!

Generally, this holds true today for most HCOL and MCOL areas. It is still a good idea to buy in a few LCOL areas.

What I have seen is that in high-earner areas (Bay area for example) buying completely outpaces renting in cost (buy to rent ratio_. Mainly because the pool of buyers outbid each other. This is mainly due to the narrative and social pressure to buy at all cost. Similarly, renting stays relatively low as people do not compete as much.

> Sometimes* the same code copy/pasted or repeated is much easier to understand than pulling it all into a subroutine.

The Write Everything Twice principle is a much needed sanity check for absurd DRY practices. There are too many naive people arguing with a straight face that writing a base class and two specialization classes saves you the work of writing two classes.

All the calculators include leverage, yes.

In fact leverage is absolutely required for real estate to even be considered an investment, and not even a good one. The fees, interest, etc are eating all the gains from the leverage.

A leverage also goes both ways. Making the housing investment so much more risky if not well timed.

Houses in Denver for example went down close to 10%. Now imagine you leveraged this...

"PHP".subst(/PHP/, 'Raku').say; #Raku

The environment we live in has become disadvantaged to the average person not only in economic terms, but in terms of life goals. The people responsible are, generally speaking, the current leadership in power, and have been holding on to that power despite their increasing age.

They have manipulated the systems to enrich themselves, at the expense of the future, and like all cyclicals in recent history, the economic pieces of it are driven by clever- re-imagingings of money-printing schemes.

Most people are worse off today than they were 20 years ago, and 10 years ago, and its still getting worse. Eventually you have 27 grievances and revolutionary activity when the vast majority of people realize there is no out, there is only through, and that involves chaotically increasing violence which no sane person would wish for, ever.
Show HN: Code Index MCP – Codebase Indexing Server for LLMs
by johnhuang316 | 2025-08-05 05:43:11+00:00
Code Index MCP is an MCP server that indexes codebases and provides search capabilities to LLMs. Supports 50+ file types with automatic indexing, regex/fuzzy search, code analysis, and real-time file monitoring.

LLMs can search your entire project, find files with glob patterns, analyze code structure (functions, classes, imports), and get automatic updates when files change. Eliminates the need to manually copy files or explain project structure to overcome context limits.

Built with Python using the Model Context Protocol. Uses pluggable search backends (ugrep/ripgrep/ag/grep).

Installation:

{ "mcpServers": { "code-index": { "command": "uvx", "args": ["code-index-mcp"] } } }

Slightly related: I die a little inside each time I see `JSON.parse(JSON.stringify(object))` thinking about the inefficiencies involved compared to how you'd do this in a more efficient language.

There's structuredClone (https://developer.mozilla.org/en-US/docs/Web/API/Window/stru... https://caniuse.com/?search=structuredClone) with baseline support (93% of users), but it doesn't work if fields contain DOM objects or functions meaning you might have to iterate over and preprocess objects before cloning so more error-prone, manual and again inefficient?

“Fewer deaths” is a meaningless concept. Every human being inevitably dies. If you prevent someone from dying today, you have only delayed the inevitable. In some cases this is extremely valuable; if you save a newborn baby, that baby could live eighty more years. If you save a 77 year old, they will not live eighty more years. And if you repeatedly save elderly people from natural conditions that could easily kill them, their quality of life gets worse and worse over time as their bodies wear out and decay and the side effects of these interventions build up. Which is why the vast majority of doctors have DNR’s.

Are they, though? Last time I checked, CO2 is going up without any "flattening of the curve". And whenever mainstream environmentalists annonce X megawatts added to the grid, a tech company announces that they need Y > X megawatts for AI. Plastic production goes up steadily without cessation every year, and there's still immense amounts of deforestation.

No, people "working" on it are intellectually amusing themselves with technology that could be a workable solution if only everyone actually took action and reduced their consumption, which doesn't need that technology in the first place. Pretty much all mainstream solutions are just psychological salves to make us think we are doing something.

Working on it, yeah right. We simply need to make significant reductions in CO2 output and no one is doing that.

Furthermore, technologies like this will make people less likely to do something about the root problem because it ameliorates it.

| The main challenge in building content-aware memory models is lack of data. To my knowledge, no publicly available dataset exists that contains real-world usage data with both card textual content and review histories.

I wonder if the author has ever considered reaching out to makers of Anki decks used by premeds and medical students like the AnKing [1]. They create Anki decks for users studying the MCAT and various Med School curricula, so have a) relatively stable deck content (which is very well annotated and contains lots of key words that would make semantic grouping quite easy) b) probably contains loads of statistics on user reviews (since they have an Anki addon that sends telemetry to their team to make the decks better IIRC), and c) contains incredibly disparate information (all the way from high-school physics to neurochemistry).

the fact is that this is a terrible feedback loop, because every time you started late, but manage to finish on time, it is reinforcing the idea that you're "good" and can manage it even if you start late! This self-reinforcing condition makes you later next time, but because of your capability, you still make it on time.

But at some point, you either stop procrastinating as you find the absolute limit, or fail outright (which is why survivorship bias exists if you look at the student body and see the amount of procrastination).
