emrehan··on Pine64 Smarphone Spare Parts
iPhone 12 models could only be serviced by Apple. A youtuber bought 2 iPhones and swapped their main boards to have a plethora of issues with the screen, battery and cameras: https://www.youtube.com/watch?v=FY7DtKMBxBw

I’m never going to buy another Apple product. The first blow was being unable to install linux to “my” devices.

emrehan··on The Science of Blockchains
I'll start from the RSA paper and see how it goes from there. I want to get to the Eth2 papers after 20 or so papers.

emrehan··on Show HN: Trueq.io – A New Q&A Platform for Developers
IMHO, the popularity of Stackoverflow is powered by search engine results rather than their community. If they fail to create such a community, it’s probably hard to establish one around a Q&A app.

In a competition like this where network effects play a huge role, your app must be orders of magnitude better for some niche. It could be about revenue sharing, decentralization or something better.

On the other hand, some other smart people work on such interesting things at the cutting-edge and make profit doing so.

I’d prefer to live with a system where frontrunning is available for anyone rather than exchanges and brokers only. So that we could upgrade the system to be frontrunning resistant for good.

There’re front running resistant decentralized exchange PoCs on Ethereum. It’s only a matter of time (and governance) before we could have this technology on Ethereum.

“Mempool” is a pool of transactions and price offered for each VM instruction rather than a queue.

Frontrunning in this context is detecting transactions that yield in profit and submitting them to the pool with a higher price for each instruction (gas price).

Good point but it won’t stop DeFi’s growth. In my opinion, such risks shouldn’t stop DeFi’s growth neither. Similar risks have been present in conventional finance and economy too. Relevant: https://youtu.be/ed2FWNWwE3I

Instead of fearing from the risks we should quantify and analyze them.

emrehan··on What Makes a Picture Good?
This post is like asking “What makes a painting good?” and answering in respect to realist paintings.

Likewise, photography is a broad discipline ranging from pictorialism to postmodernism and a good photograph is more than opportunity, emotion and execution.

emrehan··on “Pain Is the Only School-Teacher”
A good argument, but not applicable for people practicing self-harm.

A quotation from https://en.wikipedia.org/wiki/Self-harm below:

“Those who engage in self-harm face the contradictory reality of harming themselves while at the same time obtaining relief from this act.

It may even be hard for some to actually initiate cutting, but they often do because they know the relief that will follow. For some self-harmers this relief is primarily psychological while for others this feeling of relief comes from the beta endorphins released in the brain. Endorphins are endogenous opioids that are released in response to physical injury, acting as natural painkillers and inducing pleasant feelings, and in response to self-harm would act to reduce tension and emotional distress. Many self-harmers report feeling very little to no pain while self-harming and, for some, deliberate self-harm may become a means of seeking pleasure.”

Proof-of-Work alternatives that could distinguish between a human and spoofing attempts is an important problem.

This patent is about this problem but it does not put forward a solution. It's probably an attempt for patent trolling in the unlikely case that a feasible genius solution would be found.

I'd add https://pandemicvolunteers.org to coronavirus resources. It could provide the best relief.
emrehan··on Ask HN: What projects are you working on now?
I’m building a platform to connect volunteers with those in need during this global pandemic.

It should go live in a few days on https://pandemicvolunteers.org

It will start with “Hospital Support Staff” working under nurses formed from SARS-CoV-2 immune volunteers.

emrehan··on Scientists monitored brains replaying memories in real time
There is a theory on how memories are formed on neural networks through cycles of firings by an artificial intelligence pioneer. I’ve searched for it again to no avail.

Is there such a theory by Minsky?

This’s an essay on the short relationship between psychedelics and the Western culture.
emrehan··on Apple Platform Security
I used to appreciate the security features of Apple products until it began to interfere with my freedom.

I’m telling this after wasting tens of hours to install a linux, any linux to my iMac Pro without success.

emrehan··on Sundar will be the CEO of both Google and Alphabet
Since I can't edit this post, I've written my thoughts more clearly in a Twitter thread: https://twitter.com/hantuzn/status/1202179388571340805
emrehan··on Sundar will be the CEO of both Google and Alphabet
They could help with their money, but if they could help with their visions, social capital and network that would set them apart.

I admire Brian Acton in this respect. He regretted the decision of selling WhatsApp and publicized it. Since then he has taken on the leadership of Signal while donating money into it.

emrehan··on Sundar will be the CEO of both Google and Alphabet
Dear Larry and Sergey,

Thank you for creating Google.

Nobody could prove that without it the web would have been a better place. You couldn’t have known what’s to come when you were raising hundreds of thousands of dollars as two students in 1998. Maybe your leadership has been one of the least evil among the possibilities in the evil world we live in.

However, we know what is it like to lose control of your company, and how it could inspire dystopian novels under your leadership now. There’re many lessons for all the entrepreneurs to take from your story.

I sincerely hope that you would prioritize the greater benefit rather than the Google’s benefit as years pass.

Sincerely, A Non-Googler, one of the 7.7 billion

I really like this. It provides value as it is. If I were to build this, I’d focus on marketing and not try to monetize or have big expectations for 3+ years.

This is a container OS with additional security features. While it might be better, making it adopted widely would take a long effort.
emrehan··on BitMEX leaks 20k customer emails
In summary, the programmer building their batch email post tool didn’t know about the implications of adding the addresses in the TO field instead of the BCC field. They should have known about this though, as almost anyone that uses email knows.

One shouldn’t program something before learning how to do that thing probably manually.

BitMEX has many issue, I guess, that are downplayed here:

* They underestimated the importance of proper email usage.

* This functionality has been tasked to a programmer without enough knowledge on the subject.

* The code has not been tested / reviewed or reviewed competently

    * ... at the time of merge.

    * ... after it has been used in production.
