wenyuanyu··on Qwen2.5-VL-32B: Smarter and Lighter
The cycle from idea to product is a bit too long and too costly to materialize in energy sector. And that decides the speed of innovation.
wenyuanyu··on Fire-Flyer File System from DeepSeek
No, besides accessing training data, there is also logging and checkpointing... When you run k8s over it, and there are multiple training jobs... isolated local storage is a nightmare...
wenyuanyu··on DeepSeek-V3
Truly remarkable! Their approach to distributed inference is on an entirely new level. For the prefill stage, they utilized a deployment unit comprising 32 H800 GPUs, while the decoding stage scaled up to 320!! H800 GPUs per unit. Incorporates a multitude of sophisticated parallelization and communication overlap techniques, setting a standard that’s rarely seen in other setups.

wenyuanyu··on Tailscale SSH is now Generally Available
First of all, for CF, it manages the authentication part of ssh with SSO support (personally I used github)

Secondly, it has clients (on iOS it is called Cloudflare One) which can act as a VPN service as well. You can access any IP addresses (if you setup the vpc correctly [0]) directly accessible to cloudflared daemons.

How does it compare with cloudflare's tunnels? [0]

I have been using Cloudflare's cloudflared tunnels. It was great for tunneling ssh traffic behind firewalls. And it starts free.

wenyuanyu··on EU data shows PHEVs emit 350% more CO2 than tested values
Natural gas and biogas, are they both CH4? I heard they could be way worse than CO2 and leak might be inevitable to distribute them around the country and pumped into cars from time to time? Are there scientific evaluation on the impact?
wenyuanyu··on EU data shows PHEVs emit 350% more CO2 than tested values
A factor could be the limited range on a single charge, which might not meet the daily travel needs unless there's convenient access to a charging station at home or work.

Additionally, the charging process in Europe involves carrying your own cables, which adds an extra layer of inconvenience—unlike in some places like China where charging stations provide the cables. - To open the trunk twice daily to get and put the heavy cables could deter regular charging, particularly for those using their PHEV for commuting.

wenyuanyu··on A shrub in Nepal supplies the raw material for the bank notes used in Japan
Thanks for explaining! Yeah.. I was thinking of the maximum direct surface distance when saying "across the globe"... That would be 20k km... and the sea route turns to be about 10K km long from Kolkata to Osaka...

No, they are not flying non-stop from Himalaya as you assume. I did a rough calculation using [0][1]. Not including the land part, just the sea route, it is 5396 nm [0], roughly 9993 km and that is indeed halfway the globe.

By the way, from Antwerp, Belgium to Boston, MA is 3607 nm, roughly 6680 km, much shorter actually.

Sourcing the raw material of bank notes from Nepal? Seems a bit off from an environmental standpoint by hauling materials halfway across the globe from Himalaya.

How about plastic notes? They are durable, recyclable, and because they are money, not likely to end up in our oceans as wastes.

wenyuanyu··on BYD launches cheaper Seagull EV with $9,700 starting price tag
I disagree with the notion that Chinese EV makers, including BYD, have always aimed to dominate EV exports. Their focus has primarily been on satisfying domestic demand rather than targeting overseas markets like Tesla or VW.

Given that they've only 1 year something ago emerged from COVID-related restrictions, a shift to an export-focused strategy would require substantial time and effort in research, planning, and marketing to become competitive internationally. While BYD, as one of the earliest players in the EV market and with existing facilities in Mexico and the U.S., may be a step ahead, I believe they're just at the initial stages of exploring overseas opportunities. The EV market competition is likely to intensify in the coming years, but it's still early days for Chinese EV makers in the global arena.

Future automotive joint ventures (JVs) in China will cease following the completion of existing contract term.

China is lifting all foreign investment restrictions in all its manufacturing sector this year[0][1].

wenyuanyu··on New jet engine enables efficiency at every speed for cheaper orbital launches
Not sure if I understood correctly, but does this mean that instead of going up vertically, with this engine, the "rocket" should fly near horizontally and stay in the atmosphere at the right altitude until it reached the highest possible speed given the air resistance, and then lift up by the 2nd stage rocket engines?
wenyuanyu··on The Era of 1-bit LLMs: ternary parameters for cost-effective computing

wenyuanyu··on The Era of 1-bit LLMs: ternary parameters for cost-effective computing
I wonder how the training process works...
wenyuanyu··on A History of the TTY
The user interface of the current ChatGPT strikingly reminds me of the classic teleprinter interface. It's fascinating to think that, with a bit of ingenuity, one could potentially retrofit a 1960s teleprinter to interface with the ChatGPT API.

This thought leads me to ponder whether there are ongoing projects aimed at evolving this user interface into something more dynamic and interactive with LLMs. Specifically, I'm curious about initiatives that not only automatically better visualize results beyond Markdown but also "generates" innovative UI components and layouts. These would ideally support richer user interactions, such as touch, clicks, scrolling, and zooming for the input requests. Enhancing the interface in such a manner could revolutionize the way we interact with AI, making it more intuitive and engaging.

wenyuanyu··on The Fed is behind the Capital One/Discover merger
How much is the credit card fee and debit card fee in Europe? In China, it is capped to 0.6% and could be as low as 0.3% or less I believe.

I was a little bit surprised that there are no EU-based/originated payment networks. How comes?

At least, in Japan, there is JCB, and in China there is UnionPay / Alipay?

wenyuanyu··on Tiny, tamper-proof ID tag can authenticate almost anything
I don't know if I understood correctly. But it might be that the metal pieces in glues are pure random process, and there are no way to reproduce or re-print it again. The metal pieces are then recorded as a key in central database or some sort of AI, just like human fingerprint or retina how are collected and used for authentication???

wenyuanyu··on Hertz to sell 20k EVs in shift back to gas-powered cars
Honestly, H2's got a long long way (if viable at all) to go as the future of clean cars. There is not much natural H2. In a way, H2 acts like a battery as well using electricity to produce from H2O, and discharge as electricity to H2O. Producing it cleanly, like with green power, isn't efficient yet – it's only around 70% efficient. Plus, getting H2 from the factory to the customer is way way pricier than just using our current electricity grid for charging stations... Converting it to electricity is only about ~30% efficient(?) It will cost a few times more than electricity in the foreseeable future. It will be definitely much harder than have charging stations everywhere.

Not to mention the technical challenges (assume we can handle) of the low volume density, low temperature..

wenyuanyu··on OpenAI staff threaten to quit unless board resigns
I guess employees are compensated with stocks from the for profit entity. And at the face value before the saga, stocks could be like 90%, 95% or even more of the total value of their packages. How many people are really willing to wipe 90% of their salary out? Just to stick on the mission? On the other hand, M$ offers to match. The day employees are compensated with the stock of the for-profit arm, there is no way to return to nonprofit and their charter any more.
