Nobody is asking it to (except freaks trying to get news coverage.)

It's like compiler output - no, I didn't write that assembly code, gcc did, but it did it based on my instructions. My instructions are copyright by me, the gcc interpretation of them is a derivative work covered by my rights in the source code.

When a painter paints a canvas, they don't record the "source code" but the final work is also still theirs, not the brush maker or the canvas maker or paint maker (though some pigments get a little squirrely about that...)

Yeah, context management is one big key. The "compacting conversation" hack is a good one, you can continue conversations indefinitely, but after each compact it will throw away some context that you thought was valuable.

The best explanation I have heard for the current limitations is that there is a "context sweet spot" for Opus 4.5 that's somewhere short of 200,000 tokens. As your context window gets filled above 100,000 tokens, at some point you're at "optimal understanding" of whatever is in there, then as you continue on toward 200,000 tokens the hallucinations start to increase. As a hack, they "compact the conversation" and throw out less useful tokens getting you back to the "essential core" of what you were discussing before, so you can continue to feed it new prompts and get new reactions with a lower hallucination rate, but with that lower hallucination rate also comes a lower comprehension of what you said before the compacting event(s).

Some describe an aspect of this as the "lost in the middle" phenomenon since the compacting event tends to hang on to the very beginning and very end of the context window more aggressively than the middle, so more "middle of the window" content gets dropped during a compacting event.

Depends on how demanding you are about your application deployment and finishing.

Do you want that running on an embedded system with specific display hardware?

Do you want that output styled a certain way?

AI/LLM are getting pretty good at taking those few lines of Bash, pipes and other tools' concepts, translating them to a Rust, or C++, or Python, or what have you app and running them in very specific environments. I have been shocked at how quickly and well Claude Sonnet styled an interface for me, based on a cell phone snap shot of a screen that I gave it with the prompt "style the interface like this."

I don't know how rare it is today. What I do know is that it's less rare today than it was 3 months ago, and 3 months ago it was even more rare 3 months before that...

If you outsource you could at least sure them when things go wrong.

Most outsourcing consultants I have worked with aren't worth the legal fees to attempt to sue.

Plus you can own the code if a person does it.

I'm not aware of any ownership issues with code I have developed using Claude, or any other agents. It's still mine, all the more so because I paid Claude to write it for me, at my direction.

I tried using Gemini 3 for OpenSCAD, and it couldn't slice a solid properly to save its life, I gave up on it after about 6 attempts to put a 3:12 slope shed roof on four walls. Same job in Opus 4.5 and I've got a very nicely styled 600 square foot floor plan with radiused 3D concrete printed walls, windows, doors, shed roof with 1' overhang, and a python script that translates the .scad to a good looking .svg 2D floorplan.

I'm sure Gemini 3 is good for other things, but Opus 4.5 makes it look infantile in 3D modeling.

I'll put it this way: LLMs have been getting pretty good at translation over the past 20 years. Sure, human translators still look down their noses at "automated translations" but, in the real world, an automated translation gets the job done well enough most of the time.

LLMs are also pretty good at translating code, say from C++ to Rust. Not million line code bases, but the little concepts they can do pretty well.

On a completely different tack, I've been pretty happy with LLM generated parsers. Like: I've got 1000 log files here, and I want to know how many times these lines appear. You've got grep for that. But, write me a utility that finds all occurrences of these lines, reads the time stamps, and then searches for any occurrences of these other lines within +/- 1 minute of the first ones.... grep can't really do that, but a 5 minute vibe coded parser can.

Depends entirely on the app.

I don’t have time to argue with FOSS creators to get my stuff in their projects

So much this. Over the years I have found various issues in FOSS and "done the right thing" submitting patches formatted just so into their own peculiar tracking systems according to all their own peculiar style and traditions, only to have the patches rejected for all kinds of arbitrary reasons - to which I say: "fine, I don't really want our commercial competitors to have this anyway, I was just trying to be a good citizen in the community. I've done my part, you just go on publishing buggy junk - that's fine."

[–] MangoCats@feddit.it 2 points 4 hours ago

There have been some articles published positing that AI coding tools spell the end for FOSS because everybody is just going to do stuff independently and don't need to share with each other anymore to get things done.

I think those articles are short sighted, and missing the real phenomenon that the FOSS community needs each other now more than ever in order to tame the LLMs into being able to write stories more interesting than "See Spot run." and the equivalent in software projects.

people re-inventing the wheel because it’s “easier” than searching without properly understand the cost of the entire process.

A good LLM will do a web search first and copy its answer from there...

[–] MangoCats@feddit.it 1 points 4 hours ago

making something quick that kind of works is nice… but why even do so in the first place if it’s already out there, maybe maintained but at least tested?

In a sense, this is what LLMs are doing for you: regurgitating stuff that's already out there. But... they are "bright" enough to remix the various bits into custom solutions. So there might already be a NWS API access app example, and a Waveshare display example, and so on, but there's not a specific example that codes up a local weather display for the time period and parameters you want to see (like, temperature and precipitation every 15 minutes for the next 12 hours at a specific location) on the particular display you have. Oh, and would you rather build that in C++ instead of Python? Yeah, LLMs are actually pretty good at remixing little stuff like that into things you're not going to find exact examples of ready to your spec.

A prominent computer scientist who has spent 20 years publishing academic papers on cryptography, privacy, and cybersecurity has gone incommunicado, had his professor profile, email account, and phone number removed by his employer Indiana University, and had his homes raided by the FBI. No one knows why.

Xiaofeng Wang has a long list of prestigious titles. He was the associate dean for research at Indiana University's Luddy School of Informatics, Computing and Engineering, a fellow at the Institute of Electrical and Electronics Engineers and the American Association for the Advancement of Science, and a tenured professor at Indiana University at Bloomington. According to his employer, he has served as principal investigator on research projects totaling nearly $23 million over his 21 years there.

He has also co-authored scores of academic papers on a diverse range of research fields, including cryptography, systems security, and data privacy, including the protection of human genomic data. I have personally spoken to him on three occasions for articles herehere, and here.

"None of this is in any way normal"

In recent weeks, Wang's email account, phone number, and profile page at the Luddy School were quietly erased by his employer. Over the same time, Indiana University also removed a profile for his wife, Nianli Ma, who was listed as a Lead Systems Analyst and Programmer at the university's Library Technologies division.

According to the Herald-Times in Bloomington, a small fleet of unmarked cars driven by government agents descended on the Bloomington home of Wang and Ma on Friday. They spent most of the day going in and out of the house and occasionally transferred boxes from their vehicles. TV station WTHR, meanwhile, reported that a second home owned by Wang and Ma and located in Carmel, Indiana, was also searched. The station said that both a resident and an attorney for the resident were on scene during at least part of the search.

Attempts to locate Wang and Ma have so far been unsuccessful. An Indiana University spokesman didn't answer emailed questions asking if the couple was still employed by the university and why their profile pages, email addresses and phone numbers had been removed. The spokesman provided the contact information for a spokeswoman at the FBI's field office in Indianapolis. In an email, the spokeswoman wrote: "The FBI conducted court authorized law enforcement activity at homes in Bloomington and Carmel Friday. We have no further comment at this time."

Searches of federal court dockets turned up no documents related to Wang, Ma, or any searches of their residences. The FBI spokeswoman didn't answer questions seeking which US district court issued the warrant and when, and whether either Wang or Ma is being detained by authorities. Justice Department representatives didn't return an email seeking the same information. An email sent to a personal email address belonging to Wang went unanswered at the time this post went live. Their resident status (e.g. US citizens or green card holders) is currently unknown.

Fellow researchers took to social media over the weekend to register their concern over the series of events.

"None of this is in any way normal," Matthew Green, a professor specializing in cryptography at Johns Hopkins University, wrote on Mastodon. He continued: "Has anyone been in contact? I hear he’s been missing for two weeks and his students can’t reach him. How does this not get noticed for two weeks???"

In the same thread, Matt Blaze, a McDevitt Professor of Computer Science and Law at Georgetown University said: "It's hard to imagine what reason there could be for the university to scrub its website as if he never worked there. And while there's a process for removing tenured faculty, it takes more than an afternoon to do it."

Local news outlets reported the agents spent several hours moving boxes in an out of the residences. WTHR provided the following details about the raid on the Carmel home:

Neighbors say the agents announced "FBI, come out!" over a megaphone.

A woman came out of the house holding a phone. A video from a neighbor shows an agent taking that phone from her. She was then questioned in the driveway before agents began searching the home, collecting evidence and taking photos.

A car was pulled out of the garage slightly to allow investigators to access the attic.

The woman left the house before 13News arrived. She returned just after noon accompanied by a lawyer. The group of ten or so investigators left a few minutes later.

The FBI would not say what they were looking for or who is under investigation. A bureau spokesperson issued a statement: “I can confirm we conducted court-authorized activity at the address in Carmel today. We have no further comment at this time.”

Investigators were at the house for about four hours before leaving with several boxes of evidence. 13News rang the doorbell when the agents were gone. A lawyer representing the family who answered the door told us they're not sure yet what the investigation is about.

This post will be updated if new details become available. Anyone with first-hand knowledge of events involving Wang, Ma, or the investigation into either is encouraged to contact me, preferably over Signal at DanArs.82. The email address is: dan.goodin@arstechnica.com.
