treesciencebot··on AMD Ryzen Threadripper Pro 7000WX at 96 Cores and Threadripper 7000 HEDT
At least for the HEDT variant, I actually believe we are a point where we can potentially see one or more (less likely) refreshes considering the main problem with prev gen was I/O (releasing a new platform at the end of PCIE 4.0/DDR4 was not extremely wise of AMD). Obviously this is under the assumption that we’ll get a launch per year (same cycle as consumer variants).
treesciencebot··on DALL·E 3
Especially for previous generation of models (from Dall-E 2 to SD 2.1) without any sort of finetune, my experience was that you can get good results only and only if you have an amazing prompt. This obscure problem seems to be slowly disappearing with newer generation (SDXL) models or the existing fine tunes (RealisticVision).
treesciencebot··on Tell HN: Troubleshooting Slack Crashes during screen sharing on Wayland
In case you are using snap and don't mind using a beta version, I was able to get rid of the same issue by updating to the beta channel which has the 4.34.120 (sudo snap refresh slack --beta). Wayland + window sharing works (with XWaylandBrige)

> The question remains, how do we drive down the cost per NAND module. The current market NAND is due to oversupply and is not long term sustainable.

What are the current market prices for NAND modules in terms of $/TB? And how much do we need to bring it down to catch mechanical drivers (factoring in the durability of these vs mechanicals).

treesciencebot··on SUSE to go private
Is there any reason for the buyer here who already owns almost 80% of the company to offer a 67% premium for the remaining 20% of the shares? What would have happened if they offered a 30% premium or a 15% one (from what I understand, they have both simple majority and qualified majority so that means they don't really need to ask anyone for anything). It's not like they want to get 100% ownership since this is a purely voluntary buy-out and existing investors can choose to stay.
treesciencebot··on Hopin Sold for $15M After Raising $1B
> Founder sells $140million worth of secondary shares in June 2021

I wonder whether any (non-executive) employees had the chance of participating in this secondary market.

What sort of abuses you have encountered when dealing with port forwarding? Was it DMCA'd content hosting or were there other major issues with it? Also how does other VPNs that offer port forwarding (like Proton) function against those sort of abuses?
treesciencebot··on Google Invites Employees to Sleep 'On Campus' for a Fee
> If it's a work trip, it's work expenses

That doesn't probably affect the financials of the hotel though (assuming its financial profit/loss charts are totally independent from google's OpEx)

treesciencebot··on Apple reports third quarter results
Its incredible that "Services" brings as much revenue as Mac, iPad and wearables/accessories combined. I wonder what are the profit margins on services compared to traditional consumer electronics from Apple's point of view (they obviously need to sell both of them, since without hardware the software is not that useful but still it might incentivize them to subsidize the hardware like console makers in order to earn more from subscriptions).
treesciencebot··on The papers were not ready for publication
This reminds me an amazing piece of documentary[1] I've watched a couple months prior about a man who tried to "scam his way onto a Nobel prize". It really goes into showing how the majority of the system is based on trust and reputation and without well skepticism fraudsters can thrive.

Wow, this is pretty strict. If you are working from home, don't let your children or partner even see it.

treesciencebot··on Making the most of Apple Silicon power: 2 Core capabilities (2022)
This is a similar hack to what AMD does with their new 3D-series processors with two CCDs (or clusters following this article's terminology). One of them has a higher clock count but the other one has much more L3 cache. Since their target is gamers (at least at the consumer level chips), they basically ship a driver which detects when you launch a game and "parks" the low-cache CCD from being assigned tasks which effectively dispatches your processes to the high-cache ccd.
treesciencebot··on Istanbul's blue tile paradise
Especially true for south / far-east Asian cuisines. Unlike many other major western metropolises, Istanbul simply lacks any authentic chinese, indian, vietnamese or japanese places. I wish (as a resident) we had more exposure to those cultures through better / relaxed immigration policies in the past.
treesciencebot··on AMD Ryzen 7 7840U Performance Benchmarks on Linux
7950X for desktops, 7945HX for laptops. Pretty similiar in terms of the compute functionality (16C/32T) although the base clocks and TDPs are different (4.5 GHz for desktop, 2.5 GHz for the laptops as the base clock -- they both can boost much higher).

treesciencebot··on Introduction to math for game developers
The Math section as a whole seems very useful, especially for the self taught engineers (or people who need a quick memory refresh of the underlying subjects). The concepts are simplified enough that anyone with basic understanding of numbers can just jump in and learn what they might need regarding this particular field.

I wonder whether something like this (albeit a little advanced, considering the field's depth) exists for machine learning?

treesciencebot··on AMD EPYC 97x4 “Bergamo” CPUs: 128 Zen 4c CPU Cores for Servers, Shipping Now
I think we will be seeing this more and more (less cache on the die OR stacked cache on top of the main chip instead of in it) since SRAM scaling is now near a halting point [1] (no more improvements) which means the fixed code of cache is going up with every new node.

treesciencebot··on Twitch Star Signs $100M Deal with Rival Platform
It seems like 70M over 2 years, which is not that bad but also weird for a newly founded streaming startup that does not have anything unique. Looked around for a bit, but there isn't anything that really gives a clear insights on their investors/founders and how they are financing the whole deal.

Edit: I was mistaken, it seems like the site is owned by the same people who owns multiple crypto related/adjacent gambling companies so that might actually be where the "money" comes from. Source: https://twitter.com/OllyRobzTTV/status/1640542322180988929

treesciencebot··on Alphabet selling Google Domains assets to Squarespace
I wouldn't really say that for any of the new products that people actually wanted to use. Including Google Domains (even if it might not be an effective use of workforce for Alphabet).
treesciencebot··on SimulaVR's Reaction to Apple
This is an amazing point. I was also thinking about the question in the parent, but reading this now makes me realize that unlimited monitors are nice but that's not what I would want for a truly immersive "spatial computing" experience.
treesciencebot··on Addressing the community about changes to our API
As far as I understand, its 100 qpm per oauth user. Each logged-in user will have 100 qpm, so they can actually query inbox once per minute and still be left with 99 queries for that minute alone. I thought the problem was that, if you exceed this limit even for some users (e.g. particularly active ones) then you are no longer eligible for the free-tier and get kicked out of the club and pay price even for the free tier.
treesciencebot··on Turkish citizens' personal data offered online after government site hacked
Be aware that the website(s) tied to this event has been down for quite a while and there are no concrete evidence that any of them have really worked. There were a few leaks back in the 2010s but nothing recently has come up (lots of claims, no real proof).
treesciencebot··on Launch HN: Seam (YC S20) – API for IoT Devices
What's the primary difference compared to Home Assistant's programmatic interface (with each device plugging in their own API to a unified description format) or Matter?
treesciencebot··on Apple Vision Pro: Apple’s first spatial computer
Up until to the point they announced the price, apple was doing nice on the street but seems like $3,499 for a brand new platform is a bit too much risk than market was anticipating. Almost 60 billion $s went from the market cap (maybe not much for a giant in Apple's scale but still interesting).
treesciencebot··on Linux on the Xbox 360
Modern XBOX Series X and S has very nice hardware (custom AMD APUs) for a really really discounted price. I wonder when or if they can be bricked enough to be a viable linux computer that can be sold for ~250$ ish with a great performance.
treesciencebot··on Stability AI Co-Founder Sued CEO for 10 Percent of the Company
> The complaint was filed on May 18 in a Virginia district court where Waseem is based; Stability AI is incorporated in Delaware and the United Kingdom. The complaint was dismissed voluntarily by Waseem’s counsel on the same day that it was filed. Counsel for Waseem, as well as Mostaque and Stability AI, did not immediately respond to Motherboard’s request for comment.

This seems super weird (at least for someone who doesn't know how these dealings work). Any idea on why it might be filed and dismissed voluntarily in the same day?

treesciencebot··on A Reply to Josef Průša
> If "the Chinese" want to clone your product, then you are often out of luck anyway. Although that is not entirely true anymore, my previous company fought in China against clones and IP theft a couple times and won. But you need to have a local presence, a local subsidary that can hire lawyers etc.. If you are just outsourcing production to third parties then it gets problematic.

This is the take I think people are missing. If you are in a spot where "the Chinese" or any other company can cut you out, then I'm in the box that you are producing anything unique. Which was/is not true for Prusa, since even though there are clones that can be had by 1/4th of the price; people sure trust the name of Prusa to order directly from them. This is why they are the most sold printer of all time, their name is a mark of quality.

I think the main problem that now started to get them all fired up is the rise of other companies who can also provide that experience (buying something out of the shelf and start printing with it without turning this into a fully fledged hobby to learn the mechanics). Bambu Lab not only did innovate on it but also started to provide that convience for the same price, obviously they had to go cheaper in order to start obtaining market share but with true innovation they can still sell advanced printers that are maybe 1.5X in price but 2-3X worth in the capabilities compared to the Prusa (while also providing cheaper options). Now the game is who is going to dominate which sector (low end consumers [price] / high end prosumers [innovation]). If I were Prusa I'd try to aim high but not sure how well equipped are they to catch up to other printers.

treesciencebot··on The state of open-source in 3D printing in 2023
Now it is kind of funny to think about all the discussions that happened last week when the main advantage of Prusa over Bambu Lab X1C was quoted as them "being open source" and the absolutely crazy pricing was just "supporting/sponsoring Prusa's work since there are many clones thanks to their open source model". The tables turned, or they would have been turned if Prusa did either a huge change in their pricing or brought a completely new printer with features that would actually be worth the price tag.
