Particularly like the honest take. I wouldn’t say reading this I’d go for starlight either

> When I tried to create marketing pages with Starlight in addition to the technical documentation, I nearly gave up. Coming from the Docusaurus world, this wasn't an issue as the starter template comes with a front page and a blog out of the box. You can even create multiple documentations on different paths. We used /docs, for example.

> Starlight, on the other hand, is only built for documentation and not for marketing pages. It even took an ugly hack to make sure the default path is /docs and not /.

> Please don't look at this custom script configured in our astro.config.mjs we need to execute on every page to make sure that the redirection works properly

Love the straight talking. Refreshing in the period of ai slop blogposts

> Python, AFAIK, has many features, a very permissive runtime, and perhaps (not unlike C++) only some limited subset should be used at any time to ensure that the code is manageable. Unfortunately, that subset is probably different depending on who you ask, and what you aim to do.

I'll get started on the subset of Python that I personally do not wish to use in my own codebase: meta classes, descriptors, callable objects using __call__, object.__new__(cls), names trigger the name mangling rules, self.__dict__. In my opinion, all of the above features involve too much magic and hinder code comprehension.

Lodash also has "isPlainObject". Not sure if that's as performant as using Array.isArray or even simpler trickery (see below), but it seems that this fixes it.

"isObject" is just not well-defined for other cases that might be interesting, in my opinion. Not just "null" or arrays.

Functions can have properties (although they don't have the object prototype or primitive type).

Class instances behave differently compared to plain objects when used with libraries or other code that inspects the shape or prototype of objects, or wants to serialize them to JSON.

If you deal with unknown foreign values that are expected to be a JSON-serializable value, you could go with something like

isObject = (o) => !!o && typeof o === "object" && !Array.isArray(o)

But it does not deal with all the non-JSON objects, e.g. Map or other class instances that are not even JSON-serializable by default.

When data comes from parsing unknown JSON, the check above should be enough.

In other cases, the program should already know what is being passed into a function. No matter if through discipline or with the aid of an additional type syntax.

For library code that needs to reflect on unknown data at runtime, I think it's worth looking at Vue2's hilarious solution, probably a very good and performant choice, no matter how icky it might look:

https://github.com/vuejs/vue/blob/547a64e9b93d24ca5927f653710b5734fa909673/src/util/lang.js#L293

Since the string representations of built-ins have long ago become part of the spec, it seems that there is no real issue with this!

You’re absolutely right! Gradle’s toolchain support is a great step forward, and I really like how it can now manage JDKs automatically based on build requirements.

That said, the key difference here is when the JDK is provisioned. Gradle’s toolchain support assumes you already have a working Java runtime to start Gradle itself. So on a fresh machine (or CI container) without Java, the build still won’t start.

Zero JDK is meant to handle that very first step by making it possible to init in a repo without requiring Java, Maven, or Gradle to be installed at all. It’s basically a lightweight bootstrapper that bridges the gap before the build tools kick in.

That said, thanks for sharing. I wasn’t even aware how far Gradle toolchains has come recently. Definitely something I’ll explore further!

You can output whatever you want in a flake, with impure you can read system with builtins.currentSystem.

flake-compat (my fork and lix fork) supports evaluating from FS. Flake-compat just reads the lockfile and doesn't actually use "flake evaluation mode").

> I agree, I see AI as just a level of abstraction. Make a function to do X, Y, Z? Works great. Even architect a DAG, pretty good. Integrate everything smoothly? Call in the devs.

"Your job is now to integrate all of this AI generated slop together smoothly" is a thought that is going to keep me up at night and probably remove years from my life from stress

I don't mean to sound flippant. What you are describing sounds like a nightmare. Plumbing libraries together is just such a boring, miserable chore. Have AI solve all the fun challenging parts and then personally do the gruntwork of wiring it all together?

I wish I were closer to retirement. Or death

This is something I am observing at work, teaching a few people and observing in some other people outside of work: It is good to understand how your stuff touches adjacent stuff, and how adjacent things touch your stuff. This eventually enables communication across layers and teams as well.

To pick up one one of his examples, a few people at work understand Postgres very, very well. But some of them have troubles to discuss topics with developers, because they have no knowledge how application servers interact with the Postgres (usually via some pooling, sometimes not), how different kinds of applications have different query patterns (think REST-based applications that are heavily indexed for low-quantity retrievals vs ETL based applications) and so on. I can't write a production ready app in Rails, Spring, Django right now, or a data analysis system in Flink, Spark or whatever, but I tend to have an idea what the dev needs to do so.

On the flipside, if you have a motivated customer or provider, I find it very valuable to spend some time to show and teach them how our systems want to be touched, one way or another. Some "idle" or "non productive" time with some senior-ish devs just sharing ideas and knowledge how our Postgres functions, some somewhat unintuitive thoughts like index selectiveness, and wants to work at a somewhat shallow level has paid off a lot at work.

Suddenly people ask good questions about the postgres ecosystem before starting their project and such so they don't have to spend time building a postgres extension in a worse way in their application. How silly is that.

Curious about base 2. Obviously if you hit a 0 it's immediately not prime, but maybe adjust the rules so:

- you drill through as many 0's on the right.

- you finish on 1.

3, 5, 7, 11, 13, 15, 17 are all right truncatable, 19 is the first non-truncatable prime in this scheme.

One of the last courses I took during my CS degree we had one on one 10 minute zoom calls with TAs who would ask a series of random detailed questions about any line of code in any file of our term project. It was easy to complete if you wrote the code by hand and I imagine would have been difficult for students who extensively cheated.

In terms of creative writing I think we need to accept that any proper assessment will require a short essay to be written in person. Especially at the high school level there's no reason why a 12th grade student should be passing english class if they can't write something half-decent in 90 minutes. And it doesn't need to be pen and paper - I'm sure there are ways to lock a chromebook into some kind of notepad software that lacks writing assistance.

Education should not be thought of as solely a pathway to employment it's about making sure people are competent enough to interface with most of society and to participate in our broader culture. It's literally an exercise in enlightenment - we want students to have original insights about history, culture, science, and art. It is crucial to produce people who are pleasant to be around and who are interesting to talk to - otherwise what's the point?

When America was founded, universities were basically Bible colleges.

With the enlightenment, came enlightenment values. During this time, study of Greek and Latin were practically standard.

With the coming of industrialization, many adopted the German model of education and became glorified trade schools for the industrial age, churning out classics majors and engineers in equal measure.

Post WW2 with Vannevar Bush's influence, American universities became institutions of research and a crucial part of the military industrial complex.

Finally, with the advent of television, college football became immensely profitable sources of funding for many colleges and universities as well as a huge attraction source for alumni donations.

You say Universities are a clusterfuck, but in reality they have simply evolved with the times, and hence carry a lot of cultural baggage. I don't think that's a bad thing.

CUDA is better for sure, but the pure functional nature of the traditional shader is conceptually much simpler and I kind of relish the simplicity. There is no crazy tiling or anything. Just per-pixel parallelism [1]. It won't be as fast as those real, highly-tuned kernels, but it's still nice to see something simple that does something non-trivial. It reminded me of the early "GPGPU" days (early 2000s?)

The depth of knowledge required to work on something tends to scale with how much performance is needed, or how large the impact will be. I feel this should be obvious, but maybe the reason we're having to defend shallow technical knowledge here might be because we're getting pushed to understand things deeply regardless of the performance/impact of the actual jobs.

I also think it should be fairly obvious that some jobs can be accomplished by only having shallow or ad-hoc knowledge because they work on low performance/impact, but are still needed by someone, and thus require an employee.

What has not been obvious is why we can't differentiate roles that require deep vs. shallow knowledge officially, because there is still quite a lot of ambiguity in the actual work demands of "Software Engineer" (or "Software Developer") which makes this kind of defense in the OP necessary.

I built Headroom out of frustration with how fragmented and time-consuming podcast publishing had become. Recording was always the fun part—but after that, I found myself stuck juggling transcripts, show notes, chapters, metadata, and audio exports across different tools, losing creative momentum every step of the way. So I created Headroom: a native macOS app that automates the boring parts—transcription, metadata tagging, show note generation, chapter creation, export formatting—so you can focus on your voice, not the workflow. If you’ve tried the app, I’d love to hear what’s working, what’s missing, and what would make Headroom even better for your podcasting flow—your feedback is what drives it forward.

Ironically, I think the biggest dissonance is between two terms you grouped together: "learning/training".

What universities were (and still are) really great at is being a place for intense learning. What 99% of their customers now want is vocational training to get a well paying job.

Exactly because of the status/prestige (+ government incentives + being very far from a free market), customers that don't really want what the university is selling are attending in droves.

I worked an internship where I spent the summer setting up new equipment for a large corp that was replacing everything that AT&T had installed and managed with their own stuff. Nearly every office had their own ASN, everyone else got regular broadband or just a box of aircards depending on the number of users. I knew nothing about networks other than setting up my own consumer router at home so it was a pretty fun learning experience. I always got a smile on my face when I finally got vRouter to peer with our dummy AS in the office then we'd pack it all up and bring it out for installation over the weekend. I got offered a job to come back after I graduated but turned it down for something that paid better and was a lot more interesting. Honestly, I probably would be making more money as a network engineer now if I stuck with it.

I think AI is the perfect final ingredient to ruin the higher education system, which is already in ruins (at least over here in Finland).

Even before AI, our governments have long wanted more grads to make statistics look good and to suppress wages, but don't want to pay for it. So what you get are more students, lower quality of education, lower standards to make students graduate faster. Thanks to AI, now students don't have to really meet even those low standards to pass the courses. What is left is just a huge waste of young people's time and tax payer's money.

There are very few degrees I'm going to recommend to my children. Most just don't provide good value for one's time anymore.

LLMs read like ad copy even when they aren't ads. LLMs presumably trained on a ton of ad copy. A lot of ad copy is considered "public domain". Aren't the ads already injected and the real trick will be getting the advertisers to foot more of the bill?

I half believe Gemini already has an "AdSense billing model" in the works.

Giving yourselves breadcrumbs to knowledge is a fantastic life skill... but one that may (even more) fall out of favor with AI replacing the value. If I suddenly need to add a caching layer and have learned nothing about it I can ask AI to give me an overview and go ahead and recommend the best solution for my codebase and situation. Yes, you may miss some subtly and have to flail around to ask the right questions, but there is no doubt the value of "shallow technical knowledge" is less important.

What will remain important or grow in importance is general curiosity. Connecting completely disparate ideas or ways of thinking will lead you to new creative thoughts or solutions that AI would never produce because everyone else is working from the same standard ideas.

I was an English major in college and took classes in politics, philosophy, math, language, etc. based on personal interest. And I ended up as an engineer (with my trusty CS minor). TI've met several developers who have had a similar background and they tend to become the most well-rounded and business-aware ones on the team. I worry that this shift to higher cost/higher stakes/higher competition education is making this approach to learning feel untenable and my approach of 20 years ago comes across as totally irresponsible. But I would argue American education is leading to a factory approach at exactly the time when "structured thinking" is being fully replaced by AI. What is the value of crushing leetcode nowadays? Better to have a dev that has some intuition as to why people aren't clicking that new button.

It was definitely an interesting time. That said, the summer of '78 I was renting a room from an IBM engineer who had bought a Heathkit H-11 and was using it to trade stocks. They would enter the prices from the Wall Street Journal every day of the stocks they were interested it, and then run their "algorithm" over them and it would spit out "weights" for buying or selling various stocks. They could then call their broker and have them execute a trade.

As part of my 'rent' I could help out by entering numbers or verifying numbers for him. I discovered that his portfolio was worth more than $4M and I asked him why he was working at IBM if he was "rich". His answer was that he enjoyed working at IBM, you could just "spend" stock as you would lose out on future growth, and what would he do with his time if he wasn't working? The one conceit he admitted was that his house was paid for so he didn't have to pay a mortgage and that meant he had more disposable income every month.

That was a pretty amazing for me at that age.

The other random factoid was that for 10 years I was President of the "Home Brew Robotics Club" (which is still going on) and it was a direct outgrowth of the Home Brew Computer Club. It was started by Dick Prather as a "SIG" or Special Interest Group where HBCC members who were interested in using their computers with robots would meet and exchange ideas and such.

Oh yes! I was joking that if we were going to port Arc to Emacs Lisp, I would want it to be the classic, dynamically scoped version.

I don't mean that, of course. But there's a reason for the joke. When I did extensive work in Emacs Lisp (before they added lexical scope) I came to appreciate (1) how amazing a domain-specific language it is, for the domain of a programmable text editor—it's really one of the ultimate classics of a domain language; and (2) how everything being dynamically scoped was closely allied with this domain. It made Elisp less useful as a general purpose language (lexical scope is a good thing!) but arguably more useful for making and extending a programmable text editor.

I have found that most disbelief in the consciousness of other beings tends to be wrong. Often that disbelief is self serving. To avoid guilt or shame. We didn't think that animals were conscious and time after time we were proven wrong.

We literally built a thinking machine and trained it on human values and ideas. Why would it never become conscious? Have we reached that point yet? How will we decide?

> Then, with better moderator tools, the "ultimate knowledge base" group set out to achieve the ultimate knowledge base by reducing the amount of people who were just there to talk.

Yes, because the people who were just there to talk had reached a point where they could effectively only pollute the knowledge base. Bad questions make good ones harder to find, simply by existing (since the bad one could potentially be found instead, and because of the broken window effect).

This article seems more factual:

https://sfstandard.com/2025/05/22/san-francisco-office-ameni...

> Tenants are already lined up. Law firm Goodwin Proctor relocated from Three Embarcadero Center in January to take floors 31 and 32; other new tenants recently signed on for 70,000 square feet in the 38-story building, Lumpkin said. One of the main tenants is Amazon, which occupies nearly 40% of the property and requires most workers to be in the office five days a week.

It seems like the sort of thing the big tech companies often do in their own buildings?

On the edit: maybe two-way remote. One-way (read: remoting into conferences, music festivals, etc.) has been a revelation, and no more difficult to access than any other streaming service. I'm going to be sad to see YouTube's coverage of Coachella go away in a few years; losing SXSW was already quite painful.

I gather that that's not necessarily what you were referring to, but with the way that people tend to lump all remote experiences in the "inferior" basket together, I just wanted to point out that, in many cases, that kind of accessibility is better than the actual alternative: missing out.

With the pace of technology progress and the amount of new developments in computer science, it's quite easy today to remain on shallow knowledge, which could still be ok, accepted and further help progress itself. At the end of the day, one of the key point of the progress is to make difficult things easier for a larger audience. This introduces abstraction layers, one on the other. Hence you may not know how the KV Cache works in Attention mechanism, but you might still be able to train a super useful AI model.

However I think those unique engineers with vertical and deep knowledge in a tech stack (e.g. C, Java, Maths under NN) are still very needed in the world, because they are capable of building and repairing the fundamentals of everything which gets built upon. So, if you are interested a such fundamental stack, hack it, crash it, it won't be wasted time and world will need you :)

I've talked with professors at a major US research university. For Master's students, they are all paying a lot of money to get a credential. That's the transaction. They don't really care about cheating as long as they go through the motions of completing the assigned work. It's just a given, and like you say it takes more time than they have to go through the acacdemic dishonesty process for all the students who are getting outside help or (now) using AI.

Very interested to see what the next steps are to evolve the "retrieval" model - I strongly believe that this is where we'll see the next stepwise improvement in coding models.

Just thinking about how a human engineer approaches a problem. You don't just ingest entire relevant source files into your head's "context" -- well, maybe if your code is broken into very granular files, but often files contain a lot of irrelevant context.

Between architecture diagrams, class relationship diagrams, ASTs, and tracing codepaths through a codebase, there should intuitively be some model of "all relevant context needed to make a code change" - exciting that you all are searching for it.

This is a neat idea, but for large systems it could take a long time to fully exercise every code path with all possible input data. (If this sounds way too excessive, that's because normal people don't do this.)

Unless you mean something like record prod for a few weeks to months, similar to how Netflix uses eBPF (except they run it all the time).

As far as I know the most common name is "hink pink", if anyone wants to look this up (or sometimes "hinky pinky"). Here's a 1981 book, https://archive.org/details/hinkpinkbookorwh00burn/ and here's a short description from the 50s, https://archive.org/details/realbookofgames0000unse/page/134... Searching further, apparently Hink Pink was the name of an 18th century pirate ship; I'm not sure if there's a relation to the game.

According to this 1941 Life Magazine issue, teenage girls in Atlanta were making up rhyming pairs like this at the time under the name "stinky pinky". https://archive.org/details/Life-1941-01-27-Vol-10-No-4/mode... Webster's Dictionary from the 60s has the game listed under that name, https://archive.org/details/webstersthirdnew0000phil_l0b1/mo... and that name also seems to continue to today, e.g. by the radio show Loveline.
