praveen9920··on JetZero
They should have started these as cargo planes. Less compliance issues and more flight times can make it more trustable.
praveen9920··on Gaussian Point Splatting
Sorting the gaussians is the compute heavy part in gaussian splatting. So, Im guessing this will give only marginal improvement in terms rendering speed.
praveen9920··on Voyager 1 runs on 69 KB of memory and an 8-track tape recorder
I wonder if we can build a series of probes sent one after the other, which can communicate with relay network. Im sure we can reduce the power requirements for radio for each probe.

I have a feeling this feat is all about the budget requirements rather than technical feasibility.

praveen9920··on A 26,000-year astronomical monument hidden in plain sight (2019)
Having something built IRL would at least inspire a few to actually be interested in astronomy or star gazing.
praveen9920··on We replaced H.264 streaming with JPEG screenshots (and it worked better)
This reminds me of the time we built a big angular3 codebase for a content platform. When we had to launch, the search engines were expecting content to be part of page html while we are calling APIs to fetch the content ( angular3 didn’t have server side rendering at that point)

So only plausible thing to do was pre-build html pages for content pages and let load angular’s JS take its time to load ( for ux functionality). It looked like page flickered when JS loads for the first time but we solved the search engine problem.

praveen9920··on The ancient monuments saluting the winter solstice
There is a temple in India called “Konark Sun Temple”, meant to be worship place of sun god.

It is built east-west to signify sun’s journey. The temple has a wheel sort of structure which kinda acts as sundial with minute level accuracy.

In India, difference in day time between winter and summer solstices is minimal ( 3.5 hours ), I guess it doesn’t signify anything major close to equator.

praveen9920··on Epsilon: A WASM virtual machine written in Go
Nice project.!

Is there anything akin to file sockets api for wasm? I see a lot of potential in using them with go channels for ipc between multiple wasm modules.

praveen9920··on AI's Dial-Up Era
In my case, Learning new stuff is one place I see AI playing major role. Especially the academic research which is hard to start if you are newbie but with AI I can start my research, read more papers with better clarity.
praveen9920··on Who owns Express VPN, Nord, Surfshark? VPN relationships explained (2024)
Major issue I faced in this method is the network egress costs the cloud providers charge. I had to remind myself not to accidentally land on YouTube or some other video streaming sites.

Are there any cloud providers who don’t charge for network egress?

praveen9920··on Show HN: Toolbrew – Free little tools without signups or ads
Bunch of network utilities like DNS checker, ping, port scan etc
praveen9920··on Microsoft has urged its employees on H-1B and H-4 visas to return immediately
I just saw that some people on 4chan are organizing a mass booking of high-traffic route flights from India to stop some Indians from coming back. It feels like the visa process is politically weaponised for propagating racism.
praveen9920··on Engineer restores pay phones for free public use
Interestingly, someone on Reddit recently mentioned that “Pay phones started disappearing almost immediately after The Matrix movie showed everyone how to escape matrix”.

Let’s see if they will sustain :)

praveen9920··on The only time HN is this interested in Bitcoin is when there's a bubble (2017)
I remember when bitcoin post appeared first on HN. It was trending and lot of people were curious about technical details and people joking about viability as currency.

I even started mining for a brief time on work desktop which I had to uninstall immediately of course.

praveen9920··on Model Once, Represent Everywhere: UDA (Unified Data Architecture) at Netflix
Main challenge with this approach is change management of models scheme. Apart from Consensus for updating schema, maintaining versioned models across services becomes a challenge. Let’s say someone deprecates a field in schema, all services needs to update the business logic based on that which is challenging and against the ethos of distributed services.
praveen9920··on Show HN: Spark, An advanced 3D Gaussian Splatting renderer for Three.js
Any plans to extend support for triangle splats?
praveen9920··on The iPhone 15 Pro’s Depth Maps
I am waiting for a day when all phone hardwares defaulting to Gaussian splatting to take 3d images without expensive sensors. It may be computationally expensive but probably cheaper than adding expensive sensors and adding more weight.
praveen9920··on Cinematography of "Andor"
>> Right now everything is going wireless. Video is wireless. Lights are wireless. Sound is wireless. It’s all good, but there’s a lot of congestion on sets with all those things combined. Sometimes those nice tools don’t work because there’s too much technology on set

I’ve been there. Too much tech and compatibility among them is a major source of frustration. For a movie tech guys I see that as opportunity to come up with an OS where everything can be integrated where all stakeholders being users and multiple technologies working together with cohesion

praveen9920··on Triangle splatting: radiance fields represented by triangles
I think the major computational task is sorting the primitives, which works great on GPUs but not so much on CPUs. Im sure there is some research happening on sort-free primitives
praveen9920··on Triangle splatting: radiance fields represented by triangles
> The triangles are well aligned with the underlying geometry. All triangles share a consistent orientation and lie flat on the surface.

When I first read "triangle splatting," I assumed Gaussians were just replaced by triangles, but triangles being aligned with geometry changes everything. Looking forward to seeing this in action in traditional rendering pipelines.

praveen9920··on Top Patenting Powerhouses of 2024
Patents are mostly theoretical.. they are done by researchers in companies. Companies consider them as assets and holds them which sometimes increases valuation of company itself. This does not mean they want to spend money into building that may not bring them business in near future.

Best example is car companies. I heard from one of the employee that they already have research and patents to build more efficient cars but the production of those are delayed for getting the value for the research done.

praveen9920··on So you want to build your own data center
Reliability stats aside, would have loved to see cost differences between on-prem and cloud.
praveen9920··on Why do bees die when they sting you?
Stepping back a little and try to projecting that logic onto humans, are we more like super organisms? Interestingly, Our social constructs does have similarities of both superorganism and non- superorganism
praveen9920··on I ditched the algorithm for RSS
I used to use Google Reader a lot. I used to love reading through the feed but once Google killed it, I did not continue the RSS collections. Perhaps its time I get back to finding a new reader.

Heuristics for picking the most valued content is not always good. I see some posts on niche subs without much engagement, but align with my interests. Perhaps I can let a local LLM prioritize the feed based on my history or preference which I can tune as per my requirements rather than some black-box algorithm

praveen9920··on Regulations Enabling 6 GHz Wi-Fi
Going through their “economic advantage of 6GHz WiFi” document. It looks like there is a “fight” with telecom guys trying to license 6GHz for 5G and others fighting for it to be unlicensed.

Interesting to see that countries are tilting towards unlicensing even with strong lobbying of telecoms

praveen9920··on No-hole surgery: no keyhole, yet surgeons can now still operate under your skin (2023)
I heard about some resin 3d printers that work inside a resin instead of open air so that they don't need support.
praveen9920··on No-hole surgery: no keyhole, yet surgeons can now still operate under your skin (2023)
It will be interesting to see such techniques for normal 3d printing without support structures.
praveen9920··on Show HN: Watch 3 AIs compete in real-time stock trading
I think this shows more of bias of market analysis(text) rather than anything. The reasoning will mostly align with analysis.

And also pure randomness of picking the one trade from list of trades

praveen9920··on Plasticlist Report – Data on plastic chemicals in Bay Area foods
True. Also, no one is talking about tyres. They shed lot of micro plastics in their life time
praveen9920··on A pretty visualisation of the European power grid (2022)
One observation I could make from the visualization is that major cities have very big power generation centers, despite that they seem to be drawing power from surrounding areas. It is very apparent near London. I guess it is obvious that bigger cities have more demand from both industrial and residential consumption.
praveen9920··on Show HN: Jelly – A simpler shared inbox for small teams
We used to create private Google groups with corresponding team and Google would provide a shared email like sales@ourdomain.com. Now admin has more control over who gets the shared mails. It is essentially free but with few caveats.
