pavs··on To Break Google’s Monopoly on Search, Make Its Index Public
I am not even that good of a programmer and I also agree with you that index relatively trivial. Other major issues, besides fighting spam:

- Hardware infrastructure and data center presence for extremely fast search from anywhere in the world. - Near real-time search suggestion. - personalized search results based on past search + geolocation. - Search to get instant results without having to go to a website.

Just to name a few. Google Search is the gold standard of a search engine, not because its Google or because they have been around for a long time and the brand name sticks (I am sure it helps too), but for the simple fact is no search engine is even remotely close to being as good as google and I have tried them all more of the less and given them shot. They are just not good at all.

I also don't understand the hate towards google being in charge of so many products so many people use, ie, Mail, Maps, Chrome, Android, Docs (to name a few). It's simply because they are damn good at it. If its a crime to make a product so good that people continue to use it, then I don't know what else people are supposed to do. As if we are asking google to make shit products, I just don't understand the reasoning.

pavs··on The Scene: Pirates Ripping Content from Amazon and Netflix
The scene releases are usually the highest quality possible released in exclusively closed private trackers - sometimes only paid accounts are accepted as a member (if at all).

Everything else probably 95% you see in the wild are transcoded to lower bitrate and stripped out of all the extra files in the container (sub/multiple audio stream/highbitrate audio) to smalled files - because thats what most people want:

Small Video easily playable on a regular screen.

pavs··on Apple’s Low Latency HLS differs from the community-developed solution
H265 encoding/compression tech is the best in the world right now - unless I missed something.
pavs··on Apple’s Low Latency HLS differs from the community-developed solution
No, it got worse. Try H265, compression artifacts are pretty bad in certain scenarios, even with high bitrate. Same with h264 - but it can be solved with high bitrate - but your file size also gets much much bigger. Which means you will need very low latency, high-speed internet.

I think youtube is the only streaming service that does it very well without any issues for the end-user, anywhere in the world. Mostly because of their free peering service that is extremely ubiquitous. https://peering.google.com/#/

pavs··on Apple’s Low Latency HLS differs from the community-developed solution
I think OP wanted a browser-based non-flash player solution. Pretty much rules out RTMP.

I have used nginx-rtmp in the past - a very solid solution for my use case.

Re-encoding with lower bitrate. 99% of the people won't be able to tell the difference.
pavs··on Why is the ‘race to 5G’ a race?
2 more things"

- in what ungodly scenario would a consumer need 1gbps speed on their desktop, let alone on their phone. I consider myself a power internet user (I own an ISP), and even I can't think of many scenarios where I would need more than 50 Mbps of internet speed for a sustained period of time.

- On mobile devices, higher speed will almost surely result in higher power usage. When consumers are asking for longer battery life on their phone - does 5g theoretical speed really gives that, much advantage over a 4g phone? I can't think of any situation where it does.

In conclusion, 5g advantage is nothing more than to stimulate tech industry component sells to consumers and business, ie, 5g modems, phones, antennas, license fees for goverments, exporting tech stack to other countries. All these scenarios adds up to a huge financial market. The first country/company to be in this market will benefit from it. Thats whats its all about. I am not worried about snooping - the telcos and ISPs are already inside government's pocket for decades now under eecutive order (I am not only talking about USA here).

pavs··on India’s data labellers are powering the global AI race
Because of how Cloudflare works, and how ubiquitous they are, specifically, internet users from a non-western country can get bombarded with recapchas. It is so prevalent and annoying that I had to resort using VPN (located on a western country), to avoid this nuisance.

It literally breaks the internet for me, I had to go through recapchas 12-15 times a day.

The problem itself is difficult and the cost of making mistake is high. Thats why the progress is relatively slow.

Also, at least to my opinion, its not very clear that the market is big enough. Its highly unlikely that one single company can monopolize the market as there are quite a few rich companies with deep pocket and extremely talented team are investing in the same space.

If more than a dozen companies comes out with very similar performing self-driving solution. The markey may not be big enough to recoup the investment into this technology.

For the longest time I thought waymo was way ahead of everyone else - but the nature of their slow and passive progress in to the market doesn't give me a lot of confidence in their abilities.

They have a hardtime in relatively peaceful streets of developed world, how will technilogy work on the streets of developing countries where most people live?

I think the problem is extremely hard. And it will take a lot longer than most people initially though it would.

From a cursory look, it looks like he is using nginx-RTMP - one of the most widely used streaming solutions out there: https://github.com/arut/nginx-rtmp-module + ffmpeg

If you know Linux - shouldn't take more than 5-10 minutes to set it up.

pavs··on Why You Should Build a Hackintosh
Using Hackintosh as my primary driver for 3 years. no Issues. For every 1 person having vocally shared their problems, there are 100s who keep quiet, because of its working fine.

Apple hardware also has problems, yet people use them as their primary computer all the time.

Of course, there is a slightly higher risk with Hackintosh than a proper apple computer. But if your computer uptime and data is very important, the solution is having a proper backup. Having apple hardware won't make things marginally better.

Thanks for the info, I didn't know about FAIR or that pytorch came from facebook research.
pavs··on Facebook Field Guide to Machine Learning – video series
I am not trying to be a fan boy here. I am genuinely curious. What makes someone a leader in ML applications.

Google has more than studies and blog post about machine learning, apart from research and opensource ML applications, they are heavily dependent on machine learning in almost all their major product that I know of. For the most part they extremely good at it.

What and how does FB use machine learning in their product?

pavs··on Facebook Field Guide to Machine Learning – video series
> and Facebook legitimately is a leader in ML

I am curious how you came to that conclusion. I would think that Google is a leader in ML - unless I am missing something.

pavs··on Very few owners of Alexa-powered devices use them for shopping
My point was the duration of time it takes to develop a product, doesn't necessarily mean it was a well thought out product. Vista was a legendary case - The initial release was a horrible poorly thought out and broken product, that got better over the next few years with each service packs releases.

Driver-compatibility and resources usage should have been taken into account when released. Those two weren't the only major problem with the OS.

pavs··on Very few owners of Alexa-powered devices use them for shopping
Many products took years of development time, only to come out as ill-thought out and dud. Development time period is not really a scale for the quality of a product.

Some poorly thought out products that come into mind, Windows Vista, 8, IE, Android (earlier versions) - just to name a few.

People watching videos on Youtube are not SpaceX consumer/customer. Or am I missing something?

Here is a full SpaceX manifest both past and future: https://www.reddit.com/r/SpaceX/wiki/launches/manifest

As it stands right now, they are most likely the largest rocket company right now (or at least the top 2), they seem to be adding more order every other month. Not a sign of their customer base losing confidence in them.

pavs··on Fast.com now measures latency and upload speed
I was talking about international peering. If you are in USA/Europe, it's not much of an issue. Outside of that, the situation gets murky. Local ISPs don't do international peering, they piggyback on other, whose peering capacity is almost always oversold.

Yes, the last mile is the biggest expense, but other costs are not small either. An ISP with a couple of 1000 users are just reselling BW from someone else. They are at the mercy of their upstream's peering. I wasn't referring to them.

I own an ISP outside the developed nation.

pavs··on Fast.com now measures latency and upload speed
The problem with peering is that cross country peering can cost a lot of money. So if netflix does not have any caching server in your country, they will have to pull bandwidth from the closest location and your isp might have limited peering agreement with that provider.

Which many ISP understansibly will refuse to icrease peering capacity and you end up with poor bw speed from netflix or other similar providers. The solution is to do what google does with GGC nodes. Netflix also has similar service but the are very stringent and picky with which ISP they give the servers to. Google basically gives them away to almost whoever asks for it. Not to mention with all streaming and cdn and cloud providers wanting to have their own ggc like hardware at ISP premise it puts cost strains to isp in terms of power usage, rack space and high-output switch and routers at the distribution end. Not to mention all of these hardware will pull bandwidth from source (about 20%) which will come through ISPs expense.

People often like to blame ISPs. While big ISPs have legitimate problems. It also makes it extremely difficult for smaller isps bear this cost and provide service parity compare to ISP giants. Which is why you don't see a lot of isp business popping up. There is a reason google fibre is so limited in scope.

It always facinates me how most ISPs makes money at all. Then i realize the one who do has been doing it for a long time ans were already big companies when started out and probably had to take substantial loans and help from government and even then it probably took them a long time to be profitable.

They are talking about future revenue generation. Kickstarted is being used as a fundraiser.

They are probably trying something similar to ghost blogging platform.
