boysabr3··on Slack down?
Unfortunately, most billion dollar startups update their status pages post-hoc -- specially if the incidents last <15 mins.

boysabr3··on Ask HN: How to get industry insights and meet people outside your bubble?
I had a similar goal few years ago and decided to move countries and take up a job in a new industry.

It didn't quite work out for me in that industry at the end but I certainly did meet people outside by bubble + learn about how the industry works in a fairly detailed manner.

This is not the easiest thing to do, but I would highly recommend it if you have the chance!

boysabr3··on Ask HN: At what point did you incorporate for your startup or side project?
Highly recommend this Stripe Atlas guide on incorporation: https://stripe.com/atlas/guides/incorporation
boysabr3··on Ask HN: Booking.com sends raw CC data to Hotels. Is it legal?
I think you have the answer already and IANAL but just to add on, in most countries this a matter of PCI compliance that is enforced by the card networks. In most countries it's not a criminal offence to be PCI non-compliant (but you could be liable for civil suits and fines by the card schemes).

I imagine there's a clause in the PCI compliance rules that allows raw card numbers to be sent less securely if they are virtual + single use card numbers or maybe if the liability of fraud on those card numbers doesn't fall on the "original" card holders.

boysabr3··on Ask HN: Booking.com sends raw CC data to Hotels. Is it legal?
They should be using an issuing processor (a financial institution that works with Visa or MasterCard) to issue card numbers. Issuing processors can easily generate card numbers programmatically + on the fly.

I think this is what https://www.wavecrest.gi/ does. But haven't heard great things about them.

Shift payments is another option in the US - don't think they're in the UK either.

boysabr3··on Jeff Bezos is the richest person in history
Lots of friends at Amazon (US, IN, EU) who would categorically disagree on being slave driven. He is more aggressive and less favorable on "perks" than other companies in the bay area, but no where close to a slave driver (and no, I'm not taking you literally here).

I don't have data and so won't make a factual claim but can personally attest that work cultures can get significantly more aggressive / stressful / unreasonable at well funded + known tech companies in Asia. I don't think you realise how high up the totem pole Amazon is when it comes to work cultures and I also don't think you realise that there are many out there who like working at Amazon just because of it's work culture.

That being said, totally concede to the possibility that Amazon / Bezos _could_ have done questionable things starting up. I'm not aware of any but feel free to point them out.

boysabr3··on Jeff Bezos is the richest person in history
Nope, doesn't really matter if he's the richest or not. I think lots of companies could learn a lot from how Amazon innovates. I don't think you can deny that they are categorically better than many others at their size / scale.
boysabr3··on Jeff Bezos is the richest person in history
I'm always in awe of Amazon's sustained growth. Bezos has built a company that has innovated constantly (after a tumultuous start in the late 90s) and at scale:

- AWS was launched in 2006 when Amazon had < 15k employees.

- Kindle was launched in late 2007 with 20k employees.

- Echo was launched in 2014 with 150k employees.

It's no surprise he's the richest in history. Will be really interesting to see how he spends his money over the next 2-3 decades.

boysabr3··on Ask HN: Is there any scalable “blockchain”/cryptocoin?
The raiblocks White paper does an excellent job explaining why it (and other DAGs) are scalable: https://raiblocks.net/media/RaiBlocks_Whitepaper__English.pd...
boysabr3··on Ask HN: Any recommended book for social entrepreneurs?
I think running a successful social enterprise is largely similar to running a successful vanilla for-profit.

That said, I found the How I Built This episode with Perry Chen from Kickstarter quite insightful on the social enterprise topic: http://pca.st/episode/dbc5c113-aa4d-4d68-8da0-0befdf6809f8

boysabr3··on Ask HN: How do you store your programming notes?

boysabr3··on Ask HN: What's the best textbook you've read?
Haven't read it personally but heard great things about: Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp - Peter Norvig

boysabr3··on Bitcoin Visa debit cards are cancelled
I wonder why this happened. Visa is primarily a technology company - not a financial institution. It's incentivesed to keep fraud on visa cards low (so that merchants continue to accept it) and keep its ecosystem of issuers + acquirers happy.

If I'm not missing anything, I believe this must have happened because of unusually high levels of fraud on Bitcoin visa cards. Certain acquirers might've complained about abnormal amounts of "shady" volume from WaveCrest BINs.

Alternatively, Visa might have seen a settlement risk on WaveCrest's end. I.e. Visa might be worried that fluctuations in BTCs price would put WaveCrest in a position that they wouldn't be able to settle funds with Visa (and consequently the acquirers + merchants).

Any other ideas on what could've prompted this? I think if this was anti-BTC regulatory action, the prompt to turn off these cards would've come from WaveCrest's banking partners and not Visa.

boysabr3··on Ask HN: What are some good resources to learn about Crypto/Altcoins?

boysabr3··on Ask HN: What are some good resources to learn about Crypto/Altcoins?
If you're starting from scratch, I'd recommend this Khan academy course (it's short and sweet): https://www.khanacademy.org/economics-finance-domain/core-fi...

There's a lot more advanced stuff out there (as you can see in the other comments) that I would touch on once I have a rough overview.

A lot changes in the crypto world month-to-month, and so forums like Reddit and Twitter are usually the best to stay up to date. Unfortunately, there's a lot of useless chunder on these forums you'll have to learn to filter to get access to the quality stuff.

Personally, I avoid the fanboys/girls and like following people who are more critical of the space. Because of this, I've discontinued following r/Bitcoin on Reddit (I'm sure there're smart people out there—there was just too much I didn't agree with and decided to leave).

Some of my favorites today are:

- patio11 on Twitter

- prestonbyrne.com website and Twitter

- buttcoin on Twitter

- Tim Swanson (ofnumbers on Twitter)

- Bitfinexd on Twitter

- http://thereformedbroker.com/2017/11/27/it-just-got-real/

I know this is more of a crypto pessimist crowd but I tend to agree with their views way more than the rest of the herd. I think they're a lot more rational and highlight some great things to look out for.

I would encourage you to fish for some of the rational optimists as well. If anyone has recommendations, I'm all ears!

boysabr3··on Ask HN: What biographies/memoirs to read in 2018?

boysabr3··on Central bank of Ghana to hold 1% of reserves in Bitcoin
Hyperbolic title - this has merely been suggested. Not agreed upon.

As someone who has spent time working with the Ghanaian regulator on cryptocurrency education, I think they're very unlikely to do something like this (unless they're extraneously incentivised by something else or trying to do something fishy [ML]).

boysabr3··on A swarm of submarine drones will scour the depths for MH370
It would be super cool if these submarines could be made completely autonomous.

They could come up to the surface to recharge their solar batteries or maybe charge them using turbines rotated by the water movements.

They could remotely relay images and data to a publicly accessible services where they could be crowdsourced for interesting findings.

I think something like this could be useful for more than just the search for MH370 (oceanography, marine biology, etc.)

boysabr3··on Ask HN: How can we improve the world via creative, compassionate new ventures?
This might sound overly simplistic but I believe we need to do more to incentivise the best talent in the world to work on socially conscious projects. I found Wendy Kopp's episode on the How I Built This podcast particularly insightful on this topic: http://pca.st/episode/68275e4c-8d1d-4a86-be7c-e45b1eb7c738
boysabr3··on Trump admin considers tweak that may lead to mass deportation of Indians
The entire article can be summarized in these 3 lines:

> The proposal is based on the power of discretion given to USCIS officials to decide on extensions to be given to H-1B holders waiting for Green Card. They could choose to extend from one to three years, and often chose the maximum of three, and granted some visa holders as many extensions as needed. “If it has been left to their discretion,” said a lobbyist. “They can theoretically decide not to grant any extension at all.”

A better title could be: Deportation of more H1-B holders possible as Trump admin proposes pushing visa ext. discretion to USCIS officials.

I don't know much about how the USCIS makes decisions — are they likely to decline all/most visa extension requests for Indians waiting for green cards?

boysabr3··on Show HN: Read My Book Notes
Thanks for sharing this!

I've always wanted to do something like this but find it to be too disruptive to my reading process. It makes reading feel more like work and less like fun.

Curious to know how you go about writing these out? Do you write them out while reading (say after a chapter or two?) or do you jot from memory after the read?

boysabr3··on All shared Google Photos are open to the public
I think this is a fairly standard practice. This is exactly how shared links on Dropbox, Box, Mega, Imgur, etc. work. You can think of the URL as one long, and extremely hard to guess password.

Completely agree that Google Photos (and the other data hosting services) could provide warnings to those new to this method of sharing — I wouldn't expect my grandma to simply know this.

boysabr3··on Bitcoin Is Not the Future of Payments – A Glimpse from China’s Digital Wallets
Bitcoin is an asset (or a currency). Not a user experience. I think you should distinguish between the UX of a Bitcoin wallet app (which is analogous to Alipay and WeChat Pay) and the "asset" Bitcoin (which is more analogous to CNY or a stock you hold).

Bitcoin can be made user friendly with a user friendly Bitcoin wallet app. Coinbase could streamline KYC by partnering with banks / regulators, request Uber rides in-app, or enable QR based merchant payments (basically make it's app exactly similar to Alipay/WeChat Pay).

None of that has anything to do with the success / failure of Bitcoin. Bitcoin is failing because it is not a good store of value for consumers at the moment. It's too volatile and too hard to acquire. It's more of an investment class asset than a stable store of value I can purchase and not worry about.

The Alipay vs. Bitcoin comparison doesn't make sense — you're comparing apples and oranges.

boysabr3··on Bitcoin Is Not the Future of Payments – A Glimpse from China’s Digital Wallets
I don't think comparing Bitcoin to Ali/Wechat Pay is fair. One could build the same payment experiences (qr codes, ride hailing, red packets, etc.) on top of a Bitcoin wallet app. Bitcoin is a "layer" apart from the payment experiences the Chinese wallet apps enable.

Building an ecosystem of services and checkout experiences is not an incredibly hard problem for a company like Coinbase to solve. The reason why Coinbase (and other Bitcoin wallet apps popular in China) aren't aggressively cloning the Ali/WeChat Pay experience is probably because a majority of their userbases hold Bitcoin for investment and speculation — not to make day to day payments. These wallets and exchanges are better off spending a majority of their time building for these investors / speculators.
