olegkikin··on US telcos appear to be selling non-anonymized access to consumer telephone data
That's why Ghostery is important, at least it can help with the cookie part.
olegkikin··on Ask HN: Most cost effective AWS instance(s) for a UE4 render farm?
The most cost-effective way is not to use AWS, which is generally very expensive.

Figure out how much it costs you per month, then see what kind of dedicated servers that money buys. LowEndBox is a great place to find amazing deals.

Hetzner is a well-known cheap dedicated server provider.

olegkikin··on Ask HN: How do you conduct coding interviews?
Leetcode has 695 public questions. If you can memorize so many questions and answers over a week, you deserve to be hired.

Most of their questions are trivial anyway.

olegkikin··on Bitcoin Is Now Bigger Than Goldman Sachs and Morgan Stanley
The economy is not everything. It's better people use their money more rationally, rather than buying junk that they don't really need, which then falls apart and poisons our soils and oceans.

Plus it's quite clear to me that people are willing to spend their deflationary currency on the things that they believe in - the whole ICO market demonstrates it.

olegkikin··on Bitcoin Is Now Bigger Than Goldman Sachs and Morgan Stanley
I didn't say bitcoins are like computers. You misunderstood my comment.

To clarify, computer markets emulate the deflationary nature of something like bitcoin. Yet they sell just fine.

olegkikin··on Bitcoin Is Now Bigger Than Goldman Sachs and Morgan Stanley
In other words, you buy computers when you need to. Seems healthy.
olegkikin··on Bitcoin Is Now Bigger Than Goldman Sachs and Morgan Stanley
You can buy a better computer by waiting. Does that stop you from buying computers?

Considering how easily people invest cryptocurrencies into quite risky ICOs, you can see that people don't have any problem spending, as long as it's something they consider valuable.

$100 billion, not $100 million.
olegkikin··on Hyperloop One Becomes ‘Virgin Hyperloop One’
Expansion joint is likely the way to do it, but I'm not aware of vacuum expansion joints of that size. Even if it's possible, it sounds very expensive to make and to maintain. Just like everything in this project.

That's the thing about Hyperloop. It's not technologically impossible. It's just not economically viable.

olegkikin··on Competitive Self-Play
Unfortunately there are countries that don't care about your regulations. I'm not even sure a regulation like that can pass in most western countries.
olegkikin··on Competitive Self-Play
I doubt that the militaries of the whole world will just sit and ignore the AI advantages.

Something as simple as an aimbot with a scope can do a tremendous amount of damage - it doesn't get tired, it can see in the dark, it can compensate for the wind perfectly, it doesn't shake, its reaction time is in milliseconds, and it almost never misses.

olegkikin··on Show HN: Token Spread – Bitcoin/crypto spread tracking for arbitrage
I created a script years ago that looked for arbitrage opportunities on BTC-E, up to 4 trades deep, and it used the order books properly. I left it running, and was surprised that it actually found some arbitrage opportunities, around once every 3-4 minutes. Unfortunately the profits were always lower than 3-4 transaction fees of 0.2% each, so my dreams of getting rich quick got crushed.

I'm was actually surprised BTC-E didn't do something like that themselves, since the they don't have to pay any transaction fees, and they also had zero lag. It's like free money.

olegkikin··on iOS Privacy: Easily get a user's Apple ID password, just by asking
It must be an image comparison, and it's can be a simple 1-to-1, because all it takes is one modified pixel to break that. That's why it has to be some sort of an image recognition technology.
olegkikin··on iOS Privacy: Easily get a user's Apple ID password, just by asking
One solution that seems obvious to me is - the OS itself can detect fake popups such as this. It can even be a fast neural net that checks the screen, say, once a second.

Paywall.

Only problem is, 1G acceleration for 5 days straight is pure fiction at this point.

After, but not because of. It was a blood clot. Can happen to anyone at any time.

That's why security fonts were invented.
olegkikin··on Ask HN: Why aren't there more Google Search competitors?
Because it's close to impossible. To compete with Google in its primary business of search/advertising you must

1) be much better at it, or no one will switch

2) have enough money for the equipment to handle the crazy amounts of traffic

3) have enough money for the engineers to build all that

You have to realize how huge and fast google already is. You make a post/comment on Reddit, it's in the search results within minutes.

What features would it take for you to switch from Google? Even if some giant like Apple would spend billions and launch a search engine, how many non-apple users would use it? My guess is - not that many. Google has become a verb. "Just google it".

As far as I can see, you can beat google in some niches, like DuckDuckGo that rides on the wave of privacy.

olegkikin··on Internet speed guarantees must be realistic, says Ofcom
That's actually not a problem. You can always connect to 10-20 good servers (like linux distribution ones) and fully saturate your domestic connection.
olegkikin··on Persisting state between AWS EC2 spot instances
Hostus.us

The deal was found on LowEndBox, not sure if it's still available, but there are many other ones.

olegkikin··on Persisting state between AWS EC2 spot instances
If you don't care about reliability, why not just get a cheap and powerful VPS? Paying $90/month for that machine is madness. I pay $6/month for 6GB RAM, 4 cores, 50GB disk.
olegkikin··on The Bitcoin Apocalypse Is Coming in Mid-November
Please tell us when LN will launch. Not some half-baked beta that chokes on 10000 channels, but the real thing.
olegkikin··on The Truth Is Catching Up with Tesla
Can we not post paywalled garbage? Why give backlinks to something we can't see?
olegkikin··on The Bitcoin Apocalypse Is Coming in Mid-November
What if they only accept bitcoin? That's the case for most businesses accepting cryptocurrencies.

Both of you are suspiciously avoiding a direct and simple question. How does LN work on Bitcoin in this case?

olegkikin··on The Bitcoin Apocalypse Is Coming in Mid-November
In the broad terms, how do you even imagine LN to work? Let's say I want to buy a $3 coffee at some random Starbucks I'm walking by. Do we have to first open and fund the channel? How much will it all cost just for that one off purchase?

Give particular figures please, no vague nonsense I hear all the time.

As for these implementations, I will believe it when I see it. You didn't even try to address the particular issue I mentioned.

Upwork?

TopTal if you're good enough to jump through their hoops.

olegkikin··on A scientist who spots fake videos
That's not his point. He is claiming he can record a fake video that plays on a screen, and the resulting recording will look like a recording of reality, not of the screen (and the camera will sign it as such).
olegkikin··on A scientist who spots fake videos
Try it. Record something off the screen (including the audio), and see what happens. I'm yet to see one example of that that looks like reality.

Emulating a sensor sounds like it immediately reduces the number of perpetrators by orders of magnitude.

I agree though, what I'm suggesting is not 100% bulletproof, but it's using a proven technology, and it's relatively simple, assuming hardware manufacturers are willing to add one small chip to their cameras.

olegkikin··on The Bitcoin Apocalypse Is Coming in Mid-November
LN has been vaporware for a long time, and it's always 18 months before it's ready. Recently the developers openly admitted they don't know how to scale it beyond 10000+ channels, because they don't know how to solve distributed routing.
