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.

Having something built IRL would at least inspire a few to actually be interested in astronomy or star gazing.

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.

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.

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.

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.

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?

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.

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 :)

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.

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.

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.

>> 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

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

> 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 — Sun, 27 Apr 2025 12:58:05 +0000

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.

Reliability stats aside, would have loved to see cost differences between on-prem and cloud.

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
