New comment by rayval in "Detecting LLM-Generated Texts with “Classical” Machine Learning"

As I recall, a few years ago (in the era of first generation LLMs), a professor in Texas used an anti-plagiarism tool that flagged more than one-third of the class using AI in an exam, and used that finding to give them a failing grade.

If memory serves, one student objected strenously and ran the professor's own work (published 10 years earlier) into the same tool and it flagged that work as AI-generated.

"unbiased", in the world of realpolitik, means "biased in a manner to further my agenda and not yours".

In theory, the more people use the product, the more OpenAI knows what they are asking about and what they do after the first result, the better it can align its model to deliver better results.

A similar dynamic occurred in the early days of search engines.

Thanks for the ref. Not sure why that particular user got banned. A search just now on RedNote using the hashtag "gay" returns 8.7k posts. The results show plenty of men in skimpy clothing with uncovered nipples.

What is impressive to me as a software developer is that the RedNote engineering team added a Translate item to the system, at scale, within a matter of days. It works flawlessly.

I was on RedNote just now. I saw some gay content that had been there yesterday as well, and has not been removed.

BTW, the RedNote userbase in China is 70% female, similar to Pinterest in the US. That may be why there's an affinity with a portion of the Tiktok userbase. The RedNote users are not into politics (at least were not). They cats, cooking, fashion, interior decorating, travel, sports.

That would be nice, to gambol in a lush, sunny meadow, perusing a leather-bound volume that we read in the original Greek or Sanskrit.

Unfortunately, I fear we will instead end up sweaty and dirty and bloodied, grappling in the parched terrain, trying to bash members of a neighboring clan with rocks and wooden clubs, while a skyline of crumbling skyscrapers looms in the distance.

New comment by rayval in "Doomretro – The classic, refined DOOM source port. For Windows PC"

rayval — Sat, 21 Sep 2024 05:44:13 +0000

The wiki says Doomretro is 180,000 lines of code. That seems high to me, without ever having looked at the code.

I have worked on simple games in the past which are in the low tens of thousands LOC. I understand AAA games can be several millions of lines of code. Minecraft is reportedly 1.8M.

However, Chocolate Doom (the precursor for Doomretro) is around 50kloc, according to [1]. Wonder what changes were made to more than double the code size.

New comment by rayval in "Why is it so hard for the U.S. to build quality transit?"

rayval — Tue, 06 Aug 2024 05:11:05 +0000

The article mentions how global cities outside the US are building out urban rail systems.

Here's some more detail about China, which has the two largest transit systems in the world: Shanghai and Beijing.

In 1993, Shanghai had one line running 2.7 miles with 4 stations. Less than 30 years later, the system had 15 lines, 500 miles of track, and 500 stations. [1]

And in that same time frame, the Beijing subway system was expanded, from 2 lines in 2002 to 27 lines and 500 miles of track, with 13 million riders per day in 2022. [2]

Also in that time, 30 other cities in China got subway systems as well.[3]

In 1993, China's per-capita GDP was $537. By comparison, per-capita GDP in the US was 50 times larger (about $23k). Since then, the gap has narrowed. US per-capita GDP is now 5x of China (66k vs 12k).

China demonstrates that, even with small GDP, if you prioritize the needs of the people over entrenched commercial interests, it can be done.

rayval — Mon, 27 May 2024 04:32:56 +0000

I have used Microsoft Office for 20 years and Google Docs/Workspace for 15 years. I much prefer the Google suite over the Microsoft one. I prioritize quality of user experience, ease of use, performance, platform portability, freedom from constant intrusive software updates, and not messing with the built-in Emacs key bindings built into every Mac (Various MS Office programs inconsistently disable those key bindings). YMMV, esp with UI and UX, but for me there's no contest.

Regarding support, that is not an issue I have never needed it for Google, but occasionally have needed for MS Office. So I can see why if you are using Office you would value that.

To be clear, this is just a rumor passed along by Bindu Reddy. who I consider pretty well informed. Anyone have more detailed sources?
