Full-stack software engineer with over 10 years of experience creating solutions that help teams and businesses succeed. I enjoy jumping into both new projects and existing systems, learning as I go, and tackling whatever challenge the team may face, whether that’s coding, mentoring, or helping solve tricky problems. I thrive in research-heavy environments and my most unique project was building a large-scale audio streaming backend using WebRTC and custom servers.

It speaks to the quality of the SimCity games that they offer something for all ages. I also changed my perspective on a few violent scenes in games when I had a child, I could no longer stomach scenes such as No Russian (iykyk), which I had no problem at all as a teen.

When I experimented with this a few years back a true NxN room would cap around 8 people when using PCs and 4 on mobile, the bottleneck is encoding/decoding of the video. For larger rooms you need a server to route the video to all recipients, this is called an SFU. With an SFU you can have hundreds of participants, but not everyone can speak or be seen at once.

For audio-only the sky is the limit. I used to work on a voice-based social media and you also need an SFU here as well, but I added a few mixing features so that multiple incoming audio streams would be mixed together into a single outgoing one. Was very fun (and scalable).

I have way too many things that catch my interest, but right now I am designing a paper and aluminum foil based linear electric motor. The idea is to create an electromechanical display that pushes a colored piece of paper into place to create a pixel, and see if this can be done cheaply and at scale. The electronics that I have selected look very promising, all I have to do is test the idea and see if this is worth pursuing further.

The primary use for these is implementing Software-Defined Radios and the primary user of these is the military. SDRs allow jamming resistance, operation in hostile radio zones, and flexible network topologies.

Sounds like this guy did not even publish or finish the project, but only communicated his intent. The university is clearly persecuting him and he should absolutely talk to a lawyer.

A few things to consider:

- You don't have to worry too much about efficiency from the ground, since resources are plentiful unlike the sky where every gram counts. For example it would be completely fine to have a 20% efficiency from the ground to the sky (if we don't take into account the heating of the wire), for example spend 2kw to get 400w in the drone. Not ideal, but acceptable to many.

- Also, the efficiency can be greatly improved by using high voltage AC and a transformer on both ends. Very similar to how the power grid works, you can use thin cables to deliver a lot of power, I would not be surprised if 90% efficiency can be achieved. This field has been well researched, tethered drones can fly for hours, but the ranges that are useful in war (10+ km) are a novelty.

I've been thinking a lot about this setup, and it seems it's a major advantage if you can pull it off:

- The drone can send HD video with no interruptions through the fiber, shifting all the AI calculations to the backend, and you don't have to sacrifice your GPUs that you would otherwise add to the drone.

- The fiber drone can act as a radio relay, so you can have many other radio drones connected to it, making jamming much harder and also you can use it as a relay for ground forces as well.

- The fiber can potentially be replaced or augmented with copper, and you can then replace the battery with a transformer, and keep sending electricity from the base station. Such tethered drones already exist and can fly for hours, but maybe they have not been used in war before.

Well, why not have alcohol breath sensors in all cars? Why not have the car not start at all without the seatbelts being in place, and not just have the annoying alarm? Why not have the car stop going over 20 km/h if it's unregistered?

Sure I have, my objection is on the greater tendency for legislators to use technological means to constrain ordinary behavior. Today is a speed limiter, tomorrow is a embedded car snitch, or an automatic hate speech detector, or whatever else you can think of.

Next step: have a speed tracker on the car that will report speeding straight to the cops, no need for them to see you with a radar or anything like that.

In general there's lots of politicians and "administrators" who salivate at tech like this that constrain people and make them manageable. I find these attempts very undignified and totalitarian.

So this is like a helicopter propeller system, but the individual blades point upwards.

New comment by ermir in "Google to pause Gemini image generation of people after issues"

ermir — Thu, 22 Feb 2024 15:27:41 +0000

I personally think that the generated images should reflect reality as it is. I understand that many think this is philosophically impossible, and at the end of the day humans use judgement and context to solve these problems.

Philosophically you can dilute and destroy the meaning of terms, and AI that has no such judgement can't generate realistic images. If you ask for an image of "an American family" you can assault the meaning of "American" and "family" to such an extent that you can produce total nonsense. This is a major problems for humans as well, I don't expect AI to be able to solve this anytime soon.

It's more accurate to say that it's designed to construct an ideal reality rather than represent the actually existing one. This is the root of many of the cultural issues that the West is currently facing.

Normally the light of the big bang is too dim (frequency too low) to be seen, but if you travel really fast the blue shift effect will make it visible, and since this light is uniformly distributed in the sky, it will appear as while light everywhere.

Ideally you want to apply all the time, and not wait for the best time. Still, I am hoping that applicants will get some encouragement and try a bit harder in the next few weeks.

New comment by ermir in "Ask HN: Has the tech recession affected you?"

For anyone wondering about the best times to apply, conventional wisdom is that January is the best time, since it's planning season for the whole year, and then around August, to get some quick help to reach the end-of-year goals. Of course this is anecdotal and applies in normal circumstances, which I don't think the industry is at.

Struggling a lot with the response rate, once I could get one interview in three applications, now it's one in 50. I am hoping that it will pick up this January since everyone is making plans for the entire year. I was told by a manager in a large startup that they plan to complete hiring for the whole year by the end of February, and it might be the case for the entire industry.

WebRTC makes this possible, but server implementations are quite difficult to set up. I recommend you check out Pion (Golang) as a good implementation that's also easy to deploy and integrate with Node (presumably your game server is implemented in JS).

This was completely expected, at the macro level this is easily observed by measuring the outputs of metabolism and bodily function, mainly heat and physical activity. All humans have a baseline bodily temperature, meaning that the inner metabolism also is the same across all humans.
