rayval··on Previously unheard recordings of John Coltrane, captured by Frank Tiberi
the songs you mention are ones that I've played time and again for 40+ years. Never get tired of them.

Giant Steps is more abstract but still worth dipping into once in a while.

Here is a musical analysis of Giant Steps (basically the Circle of Fifths):

rayval··on 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.

rayval··on The impact of competition and DeepSeek on Nvidia
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.

rayval··on TikTok goes dark in the US
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.
rayval··on TikTok goes dark in the US
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.

rayval··on Canvas is a new way to write and code with ChatGPT
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.

rayval··on Doomretro – The classic, refined DOOM source port. For Windows PC
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.

rayval··on Why is it so hard for the U.S. to build quality transit?
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.

By the way, that is a great movie. Or do I say "was"?
rayval··on Google Meet rolls out multi-device adaptive audio merging
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.

rayval··on Beijing, Shenzhen Deserted; China's Great Depression Arrives [video]
This is flimsy propaganda with a ham-handed political agenda. This video is not alone. Multiple "observers" have been predicting the imminent collapse of China, starting 25 years ago.

Here's a list of 25 such predictions in an almost yearly cadence: https://x.com/rippinkitten18/status/1701411830642741348?s=20

In the meantime, China has outpaced most Western countries with steady growth.

One notable "expert" is Paul Krugman, who predicted Chinese doom a couple of months ago. Turns out he made a similar prediction ten years ago: https://x.com/NuryVittachi/status/1701400962957746544?s=20

For an accurate street view about Beijing recorded over the past 2 weeks, here are two random videos that show a bustling and prosperous Beijing, taken by Western travelers:

rayval··on TikTok Is Destroying Itself from the Inside Out
On Twitter, I never use to get spam DMs but now it is a daily occurrence. I never blocked anyone over 10 years but now I am blocking multiple people per day. I used to never see anti-semitic content, but now I run across it regularly (even though I don't follow similar accounts). I still enjoy interesting discussions on crypto and genAI tech/trends but that is probably not a broad enough audience to be sustainable for Twitter/X.

rayval··on How to Replace Your CPAP in Only 666 Days
Yes when I first moved to the US, people would greet me with "How ya doing?" and I thought they really did want to know. It took a while to understand that it was just a way of saying hello.

I'm told that, in China, a way to greet someone is to say: "Have you eaten yet?" 你吃了吗

You are not supposed to provide a detailed answer such as: "Yes I ate a breakfast sandwich this morning at 8 am".

Instead you simply say "I ate" (吃了) or "Nope" (没呢)

rayval··on One year post-acquisition, X traffic and MAUs in decline, report claims
I am still a regular user, but it has become more of a chore than a joy. The lively exchange of ideas without agendas (or with less of an agenda) is absent. Instead I do get some useful information about tech industry trends by some stalwart contributors. Also my spam-and-scam messages have gone up by 10x.

I suppose I could make more effort to mine other sources like Medium or decentralized Twitter clones, but haven't yet done so.

I'll put up with the dreariness and annoyances of X for now, but the instant I find a better alternative, I'm gone.

rayval··on China Bans iPhone Use for Government Officials at Work
"Secretly dreaming" sounds like a thought-crime.

In terms of real-world actions, the US has more 750 military bases in 80 countries, including 300 in Asia.

China has 8 overseas bases: one in Djibouti and the rest in islands near China.

China is definitely trying to advance its economic interests throughout the world, by investing in infrastructure in Africa and Latin America.

That's what every country does or aspires to do. It's just business.

Better transparent soft power that delivers tangible results for the local populace rather than opaque coups, mercenary armies, and funding dictators and warlords.

rayval··on AI Is Catapulting Nvidia Toward the $1 Trillion Club
Economic dislocation will lead to rise of angry/insane populists/nationalists (like Trump 2.0) in multiple regions. Already a trend, will get worse. One unfortunate but plausible outcome is catastrophic global conflict.

To avoid this, countries need to plan for and mitigate the social effects of economic dislocation, such as UBI. Unfortunately that ain't gonna happen. Brace yourselves.
