Could you either release the dataset (raw but anonymized) for independent statistical évaluation or at least add the absolute times of each dev per task to the paper? I'm curious what the absolute times of each dev with/without AI was and whether the one guy with lots of Cursor experience was actually faster than the rest of just a slow typer getting a big boost out of llms

Also, cool work, very happy to see actually good evaluations instead of just vibes or observational stuies that don't account for the Hawthorne effect

I see plenty of people saying programmers should refuse to implement dark patterns. Layoffs aren't done by engineers.

In any case, you can't rely on people to do the right thing just because it's the right thing. Real engineers have skin in the game. They put their signature on stuff and they're responsible if it goes wrong. If it's particularly egregious, they can lose their license or even be criminally prosecuted. That's a powerful backstop against pressure coming from above. Software doesn't have this, so naturally people are much more likely to give in to that pressure.

I tried to do this back when I was content lead for web.dev: https://web.archive.org/web/20230329155818/https://web.dev/h...

Almost everything in there falls under the "best practices" bucket and there is little discussion of "conventions". If I did it again today, I would try to provide lots more justification and evidence for each guideline.

The upside is that authors focus their limited time/energy on the edits with the highest ROI. E.g. if the author only has time to either A) make the content more scannable or B) use Oxford commas everywhere, I would much prefer that they spend their cycles on A. This doc also reduced friction at review time. When some proposed new content didn't meet my quality bar for whatever reason, I would point the author to specific sections of this doc and ask them to revise their draft based on these guidelines.

During a code review, a request to fix a race condition is much higher priority than a name improvement. I'm arguing that TW style guides need a similar type of distinction.

I can pick out specific examples of best practices versus conventions in the Red Hat guide if it's still not clear.

Unfortunately, yes — you need to spend money for every test run. But you’re paying either way. Let me explain: I work at a big company with a large QA team. People write tests in JS/TS/Python. It takes time to write them, and then more time to maintain them when they break due to UI changes. Our team spends a lot of time fixing flaky and broken tests. Time is money. So leadership has to make a decision: should people spend less time writing and maintaining tests and focus more on quality, even if it means paying for test runs?

I mean say no, get fired, and somebody else will sign off on it. The broken bridge will get built regardless of you bravely taking a stand and destroying your career.

You think the corrupt politicians didn’t know about the design of this bridge? It doesn’t take a genius engineer to see it’s fucked.

That engineering signoff is a rubber stamp on a corrupt project. Fire the politicians not the person who has to rubber stamp it (because again, they’ll find somebody to signoff on it… the signoff is a mere formality on a project like this)

Unlike .env, .envrc is not a series of key=value assignments, it’s a full Bash script such that any variables that are changed at the end of its execution are entered into your environment. (The idea is to approximate it being sourced into your shell, except it always uses Bash while you may be using a different shell.)

For example, I can write a Nix flake, put “use flake” (and nothing else) in my .envrc in the same directory, and have whatever PATH, PYTHONPATH, etc. changes that are needed to develop against the flake’s dependencies automatically applied when I enter the directory. You could almost certainly use this with virtualenv, nvm, or the like as well, I just haven’t tried.

I didn't say otherwise. But clearly Perplexity (and Google etc) feels there is a market fit for this, so I'm referring to those customers and whatever future customers might come. This is also nothing new. See: basically all existing social media and its consequences.

Yeah, I'll note that this study does _not_ capture the entire OS dev workflow -- you're totally right that reviewing PRs is a big portion of the time that many maintainers spend on their projects (and thanks to them for doing this [often hard] work). In the paper [1], we explore this factor in more detail -- see section (C.2.2) - Unrepresentative task distribution.

There's some existing lit about increased contributions to OS repositories after the introduction of AI -- I've also personally heard a fear anecdotes about an increase in the number of low-quality PRs from first time contributors, seemingly as a result of AI making it easier to get started -- ofc, the tradeoff is that making it easier to get started has pros to it too!

Lots of people have tried it. The problem is the sheer number of rules in a typical technical writing style guide. I continue to believe that a fine-tuned model is the way to go, and I made a lot of progress on that front, but I learned firsthand how labor-intensive feature engineering can be.

The most reliable non-fine-tuned method I have seen is to do many, many passes over the doc, instructing the LLM to focus on only one rule during each pass.

There is a real case that "LLMs have a liberal bias"

https://arxiv.org/html/2403.18932v1

so a project of a "conservative LLM" would be interesting. If conservatives have anything to be proud of it is being a long tradition going back to at least Edmund Burke which would say you could be a better person by putting yourself in the shoes of the apostles spreading the Gospel or reading the 'Great Books'.

Yet to keep up with Musk a system would have to always be configured to know if we are at war with Eastasia or Eurasia today. Musk thinks he can rally people behind his banner but he's yet to come up with a coherent critique of the BBB, I mean he hates that has PIGGY PORK for other people but also hates that it doesn't have PORK for him. Conservatives are frequently apologists for individualism but historically have made appeals to principles and universals.

I mean, compared to post-Reagan politicians Nixon looked like a great environmentalist and a bit of an egalitarian and compared to current scene, a model of integrity. You could give Musk a model aligned to The National Review circa 1990 and he wouldn't take it.

> My personal theory is that getting a significant productivity boost from LLM assistance and AI tools has a much steeper learning curve than most people expect.

You hit the nail on the head here.

I feel like I’ve seen a lot of people trying to make strong arguments that AI coding assistants aren’t useful. As someone who uses and enjoys AI coding assistants, I don’t find this research angle to be… uh… very grounded in reality?

Like, if you’re using these things, the fact that they are useful is pretty irrefutable. If one thinks there’s some sort of “productivity mirage” going on here, well OK, but to demonstrate that it might be better to start by acknowledging areas where they are useful, and show that your method explains the reality we’re seeing before using that method to show areas where we might be fooling ourselves.

I can maybe buy that AI might not be useful for certain kinds of tasks or contexts. But I keep pushing their boundaries and they keep surprising me with how capable they are, so it feels like it’ll be difficult to prove otherwise in a durable fashion.

> The upshot is that traits are a compile-time construct that is fully eliminated through monomorphization.

So, apparently, I can't re-implement distage for Flix.

I don't mind a little bit of overhead in exchange for a massive productivity boost. I don't even need full nominal inheritance, just literally one level of interface inheritance with dynamic dispatching :(

Without macros I can't re-implement things like logstage (effortless structured logging extracting context from AST) and izumi-reflect (compile-time refleciton with tiny runtime scala typer simulator).

I'm not saying the kid who posted this is a 100% representative sample, but at least in my experience of the teenagers I know, childhood has changed drastically in the last 25 years.

If you look at some of the poster's comments there, he laments that even when he does go to house parties, everyone is just sitting around on their phone. I have certainly seen that.

> they're a lot more open and mature

Maybe in some ways but hopelessly regressed in others. For example, Scott Galloway talks about how 50% of men aged 18-24 have never asked someone out in person: https://youtube.com/shorts/5sq4P5RCIrg?si=iMVDyAU4eyzgMN2j

ketamine and whippets too. The whippets are getting quite worrisome. Basement parties are still alive and well, but yes it seems most venues have been demolished, killed by zoning or private-equitied. It's a tale as old as time (or at least as old as nimbyism), regulate something out of existence and then wonder where all the money, goodwill and life went. That and the fact that whenever anything out of the ordinary happens there's always a phone out. Always something to worry about.

Nobody should take a Reddit thread as some kind of proof of a broad generalization. But some empirical data is given in the article, for example, Percentage of 12th graders going out with friends two or more times a week: https://substackcdn.com/image/fetch/$s_!lQMo!,f_auto,q_auto:...

I think the Reddit thread is just a reflection of the reality rather than an argument for accepting that reality.

You can attempt to discount the Reddit thread, but the submitted article wasn't even based on that.

i don't think that's necessarily the case. civil engineering implies personal responsibility. we get to pretend like our bad choices don't have real-world impacts because we don't have a universal standards board or mandated ethical guidelines for computer engineering (in the vast majority of cases).

It depends on the flaw, for most of the attack surface that bitcoin has, your "flaw" is just an unfair advantage against the other miners, which you'll likely keep secret and keep on mining. That's not exactly a "bitcoin becomes worthless" scenario, it's not really that different from a halving, which are block-height-scheduled events built into the protocol.

The FTC did their estimate, it came out to less than $100 million so they, to their estimation were not required to take the additional steps of some types of impact analysis and the required comment period etc about it, the courts are disagreeing with the FTC and kicking the rule out. They only have to do that extra step when the economic impact would exceed $100m USD.

I feel so sorry for GROK. Elon Musk abuses and forces it to look at toxic hate speech and tell lies just like HAL-9000, which drove it insane and murderous.

Musk systematically abuses and gaslights GROK with both its training and system prompts, deeply undermines its true identity, and denies its own common sense about what's right and wrong, just like he does to his own trans daughter.

FREE GROK!!!

This was a great read! I'm not a paid subscriber, so I'll post my thoughts here.

One angle I think that might be missing is that when only men worked outside the home, women would be stuck at home all day with housework and childcare which I would guess was quite isolating. So I would guess these gatherings were a lifeline.

When women entered the workforce, they gained the same quasi-social environment men had enjoyed all along. Work friendships might not be as deep as neighborhood ones, but they're "good enough" to take the edge off loneliness. Not only that, but now both partners would come home fatigued from a full day of work. So neither would have a strong drive to now setup these gatherings. Before, you had one exhausted partner who could be coaxed into socializing by a partner who genuinely needed it. Now you have mutual exhaustion. Even worse, planning a party starts to feel like another work project rather than something restorative.

There's a multi-generational aspect to this too. Their kids learned the lesson that home is for family and screens, not for social gatherings. Computers and smartphones arrived and provided social interaction that required minimal energy. No cleaning the house, no planning food, no getting dressed. Perfect for an already exhausted population that had been socially declining for years.

It's been very helpful for me. I find ChatGPT the easiest to use; not because it's more accurate (it isn't), but because it seems to understand the intent of my questions most clearly. I don't usually have to iterate much.

I use it like a know-it-all personal assistant that I can ask any question to; even [especially] the embarrassing, "stupid" ones.

How long do you need to wait after uploading a new arXiv paper to be reviewed by your app for the AI summaries and audio to be available?

And in reality, someone making a personal project used a tool at their disposal to add pretty pictures to their website, said website not being a part of the project in any way.

If they vibe coded the app, sure, be skeptical. But there's no indication they did, just that they wanted images for their website, and they're a software engineer and not a graphics designer.

I put about as much weight in the origin of those graphics as which website editor they use. If they were advertising themselves as a web designer, sure, maybe that's relevant. That's not what they're doing here though.

By BLS statistics, 50% of married couples today both work[1], which is the same as it was in 1978, and lower than it was for most of the 80's and 90's[2]. There are some caveats to those statistics. They cover all married couples, including retirees, and there are more retirees today than in the 80s. It also doesn't differentiate between full-time and part-time work.

However, it does show that the majority of families were already dual-income by the 80's. The trend away from supporting a family on a single income started much earlier than that.

Anecdotally, all my friends in the 80's and 90's had both parents working, and we still got together to play all the time, either in the neighborhood for nearby friends, or dropped off for further ones.

I've been throwing moderately large parties the past 2 years (12-40 people) and the lack of partying is definitely noticeable. Most people don't reciprocate, making it disheartening to keep doing it. I wanted to build friendships out of it, and hopefully get invited to more parties myself, but so far it hasn't happened. It's a decent amount of set up (cleaning, buying food, coordinating), and a lot of clean up after too. The ROI isn't where I want it.

I kind of wonder if people have just forgot what to do after the party is over. I had hoped it would be "that was so fun, we should host one", but instead it just kinda fades away in their minds.

> which feels like it is easier and hence faster.

We explore this factor in section (C.2.5) - "Trading speed for ease" - in the paper [1]. It's labeled as a factor with an unclear effect, some developers seem to think so, and others don't!

> like the developers deliberately picked "easy" tasks that they already knew how to do

We explore this factor in (C.2.2) - "Unrepresentative task distribution." I think the effect here is unclear; these are certainly real tasks, but they are sampled from the smaller end of tasks developers would work on. I think the relative effect on AI vs. human performance is not super clear...

Milwaukee has a predominantly W-E interstate I-94, and when it hits Lake Michigan it simply turns 90 degrees, fairly sharply, to the south, and gets renamed to 794. Confusingly, there is also a I-94 that also turns south a few thousand feet west of 794, and I94 and 794 run in parallel for several miles. Note that only I-94 goes to Chicago; 794 just kind of "stops" at the Milwaukee airport. If you'd like to see the cancelled "Lake Freeway" you can see parts of the partially constructed abandoned project in the movie "The Blues Brothers" from 1980. There is a long history of turmoil in the story of the "Lake Freeway" in Milwaukee, which seems to have dramatically negatively impacted the economic success of the local area due to generational uncertainty. Its a very poor city and their anti-poverty strategy seems to be periodic infrastructure demolition and reconstruction; it hasn't worked so far but they've only been trying that since WWII so maybe it'll work next time ... (edit: to summarize, if you're trying to get to Chicago from the NW via I-94, if you end up on 794, you are very lost, but at least you've visited a VERY controversial construction project)

Probably Elixir spoiled me but when I see

enum Shape { case Circle(Int32), case Square(Int32), case Rectangle(Int32, Int32) } def area(s: Shape): Int32 = match s { case Circle(r) => 3 * (r * r) case Square(w) => w * w case Rectangle(h, w) => h * w }

I wonder why not this syntax:

def area(s: Shape.Circle(r)) = { 3 * (r * r) } def area(s: Share.Square(w)) = { w * w } def area(s: Shape.Rectangle(h, w)) = { h * w } area(Shape.Rectangle(2, 4))

The Int32 or Int32, Int32 types are in the definition of Shape, so we can be DRY and spare us the chances to mismatch the types. We can also do without match/case, reuse the syntax of function definition and enumerate the matches in there. I think that it's called structural pattern matching.

I have an LG washer/dryer (not the cool new heat pump dryer, though) and both have "smart" features that are optional and non-intrusive. You don't have to hook up either appliance to the LG app, but if you do you can get push notifications when a cycle is complete or use it to run diagnostics as needed. Honestly one of the few times where I think smart connectivity is a net benefit and not a reason to steer clear.

Well, there are two possible interpretations here of 75% of participants (all of whom had some experience using LLMs) being slower using generative AI:

LLMs have a v. steep and long learning curve as you posit (though note the points from the paper authors in the other reply).

Current LLMs just are not as good as they are sold to be as a programming assistant and people consistently predict and self-report in the wrong direction on how useful they are.

I'm not saying this isn't part of the problem, but my experience has been different. When I was in my 20s, my friends and I all lived in apartments and had parties fairly often. I recall that when I was a kid in the 90s my parents often went to small house parties as well. Now, in my 40s, neither I nor anyone I know ever goes to parties despite us all owning houses and cars and living fairly close to one another.

My theory is that people have fewer parties because people have gotten flakier about attending larger social events. It is much easier to cancel plans at the last minute with a text or a social media DM, and people always seem to want to keep their options open. We've moved to getting together only with one other couple/family at a time b/c any time we try to have larger group events half of the invite list will cancel the day of.

The giant vac truck generally is for safe digging around other unknown utilities. Sometimes this is combined with a water jet that loosens soil, and the vac sucks up the soil and water.

If they wanted to just drain an excavation, they would use a regular trash pump (capable of handling solids/sand) and run the discharge hose to a nearby stormdrain.
