wensheng··on Ghostty 1.4
Judging from kitty benchmark, 1.4 is much faster than previous version 1.3.1. Vivido[0] was the fastest terminal when i measured terminal performance a month ago. Now Ghostty is the fastest. Time to catch up.

wensheng··on State-of-the-Art Chatbot, Vicuna-7B, now runs on MacBook with GPU acceleration
super helpful, thank you.
wensheng··on Using mmap to make LLaMA load faster
How did you distribute the weights between CPU and GPU? Thanks
wensheng··on Hard Data on Remdesivir, and on Hydroxychlorquine
Ahh, the infamous RECOVERY trial, where they give patient dangerous high dosage(2000mg first 24 hours, 800mg each for next 9 days). Also they probably made the decision to stop the trail after that (now retracted) study[0], lots of trials stopped after that study came out.

wensheng··on SARS-CoV-2 Is an Unrestricted Bioweapon (The 2nd Yan Report) [pdf]
For anyone who has doubt about her qualification on Covid-19, she is co-first-author (one of 3 equal contributing first authors) of Nature article "Pathogenesis and transmission of SARS-CoV-2 in golden hamsters"[0]

She is also the actual first author of this paper "Antibody Profiles in Mild and Severe Cases of COVID-19"[1]

The 2nd paper was submitted by her, accepted after she had left Hongkong, so other authors removed her name from the paper, but I guess they still had a little bit of decency left, they acknowledged her (as Scarlett Yan) at the end of paper. This paper, according to a researcher who developed the cocktail covid drug at Regeneron, was very informative and helpful to covid drug and vaccine development.

wensheng··on Unusual Features of SARS-CoV-2 Genome Suggests Sophisticated Lab Modifications
I didn't notice the tone, but there must be some of it. I think the author tried their best to sound neutral but if they strongly believe what they believed it, it's unavoidable for letting personal opinion slip in. I once asked one of the author - nerdhaspower, to remove such words as "中共" from his site because they show confirmation bias. He refused. But in this paper, they did a much better job.

I don't believe the paper implied what you said. The first reference for example, also a well-written paper, is from a Harvard researcher, who has nothing to do with the organization.

wensheng··on Unusual Features of SARS-CoV-2 Genome Suggests Sophisticated Lab Modifications
oh, thanks. That post is also flagged.

HN community are extremely liberal. When they see Steve Bannon name, they automatically reject the paper. I wouldn't trust the comments, even if they claim they are subject experts here.

wensheng··on Unusual Features of SARS-CoV-2 Genome Suggests Sophisticated Lab Modifications
Why is this flagged?

This is a scientific paper written by 4 Ph.D's. It uses "rule of law society" as affiliation because this is the organization that helped the main author Dr. Yan escape from Hongkong. Dr. Yan has published in Nature, Lancet, Virology as first authors. The 3 other authors don't want to list their real affiliations because they want to remain anonymous. One of them is a professor at a US University. The other two are accomplished scientist in their own fields.

This is not conspiracy theory, this is candid scientific study and discussion of upmost importance.

Why is this buried?

wensheng··on The new business of AI and how it’s different from traditional software
I am not sure what the difference between this and the "option 2" in the post you replied to. Some examples would be helpful. It seems to me both options replace human intensive tasks.
wensheng··on The Effect of Cold Showering on Health and Work (2016)
It says old showering reduced self-reported sick leaves but not illness days. So it's not conclusive it has real benefits.

I guess lots of HNers shower cold, they like hearing it having potential benefit so they can feel good about themselves. Lots of confirmation bias here. The top voted comment doesn't discuss TFA, but just how great cold showering is.

In the study, a 90-seconds subject died, most likely not because of cold shower, but you never know, without the the experiment, he/she probably would have lived. His/her family members probably blamed cold-shower for it.

Dr. David Sinclair advocates cold-showering, said it increase brown fat. But the evidence he cited[1] (Lifespan page 110), the short term cold exposure is 4 hours, the temperature is probably lot colder than cold shower, so it's doubtful a 30/90 second cold shower help growing brown fat.

wensheng··on Ask HN: Where do you get your cheap servers?
AWS EC2 reserved instances, pay upfront for 3 years, it works out cheaper than digitalocean/linode.
wensheng··on China Detains Former U.S. Air Force Pilot Flying for FedEx
I've been to about 20 national parks each in US and China. I'd say on the whole China has better natural scenes. The problem with China is the crowd. Every where you go, there's huge crowd, which ruin the experience.
wensheng··on Ask HN: What are your favorite books or essays written at least 100 years ago?
I'm pretty sure it's not abridged because it's 3 books, each a few hundred pages.
wensheng··on Ask HN: What are your favorite books or essays written at least 100 years ago?
2 years ago, I replied a similar question by saying The Count of Monte Cristo is my favorite book in my youth. I finished reading the Chinese version on one day when I was 16. Since that comment my son was given the book (English) at the same age for his English class last year, he finished it in more than 1 month. I think I have failed as a parent (by not forcing him to learn to read).
wensheng··on In China, tattoos border on illegal – and they're his life's work
I don't understand tattoo, it's like wearing the same cloth (i.e. a T-shirt) every day, for the rest of your life.

I do think there's market for more colorful, longer lasting temporary tattoos. (Might be a startup idea for ya)

wensheng··on OpenDroneMap – Simple Images into 3D
this might be off-topic, but anyone know a good software for indoor use? i.e turning indoor images into indoor 3D models.
wensheng··on Chinese TechCrunch Rival 36Kr Is Said to Plan Overseas IPO
I followed 36kr.com from its beginning. In its first 2 years, HN is the source for 80% of the its articles.
wensheng··on Microsoft Adds an OpenSSH Client to Windows 10
It seems it only available in Administrator mode, to enable it for normal user, you have to add "C:\Windows\System32\OpenSSH" to your PATH.
wensheng··on Ask HN: What are your favorite books of all time, and why?
In my youth, my favorite book is The Count of Monte Cristo, in college it is The Mind's I by Hofstadter and Dennett. (Actually for both I read their Chinese translations as I was in China). My favorite English book is The Fall of Hyperion.
wensheng··on Review of Jean Bricmont's book "Making Sense of Quantum Mechanics"
thank you
wensheng··on Apple joins the NFC party, providing iOS developers the ability to read NFC tags
Might be off-topic, but anyone know what other techs provide indoor distance tacking/localization other than BLE beacons? WIFI's accuracy is too low.
wensheng··on CertBot: Automatically enable HTTPS on your website with Let's Encrypt certs
Simp_le does the same thing. I use simp_le with Haproxy on one server and nginx sni on another. Works very well.

wensheng··on Ask HN: What is the most mind blowing book you've ever read?
The Mind's I, by Douglas Hofstadter and Daniel Dennett

Blowed my mind when I read the Chinese translation of this book 25 years ago in College.

wensheng··on Microsoft makes it easier to build Minecraft Mods using Visual Studio
With the said RaspberryJuice you don't need to have a Raspberry Pi.

I wrote a RaspberryJuice+Python command server so you can have run python functions inside minecraft. [0]

wensheng··on $15 Dedicated servers from OVH
Are you OpenVZ only? Can I deploy my own Xen VPS on it.
wensheng··on TypeScript: a language for application-scale JavaScript development
No list comprehension? No, Thanks.
wensheng··on Program above and beyond your actual ability by using FreeMind
There's a Freemind fork called Freeplane ( http://freeplane.sourceforge.net ) that has some additional features.

There's also non-opensource xmind ( http://www.xmind.net/ ) that's much faster than Freemind/Freeplane.

wensheng··on How to run your own open source Skype replacement
Thank for the info.

Have you considered of using Freeswitch to replace Asterisk and maybe even your own media relay module?

wensheng··on How to run your own open source Skype replacement
It appears to be based on Asterisk, with Mysql and Apache.
