rayvy··on Ask HN: What's the current sentiment on JWT for stateless auth tokens?
> Wasn't the question about using them for auth, not application state?

Whether a user is auth'd or not can indeed be a form of application state

rayvy··on Ask HN: Is there a better employment route to high earnings than FAANG?
> It feels dreary because you feel you have nothing left to strive for because you're only measuring your progress by your salary

This.

In your post you mentioned nothing but salary. Sadly I think you might find the hard way that the whole FAANG salary rat-race isn't/wasn't the best choice

rayvy··on How we built Uber Engineering's highest query-per-second service using Go (2016)
I think this write up is very fair for a solid engineering team. Is it groundbreaking and eye opening? Absolutely not, I’d say the most “hmm I didn’t know that” part of the entire thing was the part about R-Trees and S2. Is that bad? Absolutely not. These guys did the work, logged their performance and are sharing their story.

However, and I believe this is where the animosity in the comments is coming from - given the elitist (for lack of a better term) attitude of these engineering types at these orgs (think of the poster children of the Valley), this is pretty...lacking. I mean, the part about using the Read/Write lock on the second attempt and instead trying to go with an installed package just screams Node.js, and honestly made me chuckle. I guess Leetcoding and Production Engineering really are different things. I genuinely expected more.

rayvy··on Ask HN: Why don't streaming services make use of P2P?
That's cute ;)
rayvy··on Ask HN: Why don't streaming services make use of P2P?
P2P is for decentralization. Why would a centralized entity want to implement a decentralized service when they can create a centralized version of that same service faster, easier, and cheaper?

P2P is _hard_ with a capital H.

rayvy··on Ask HN: Which stack will get my MVP API off the ground fastest?
This is kind’ve a bait question. I mean the “no duh” answer (as others have already mentioned) is “whichever you are most comfortable with”. I’m confused as to what other answer you could want
rayvy··on Ask HN: Founders, if you had a time machine...
Seconded. Would also love to know these things.

Side note: Would definitely change the title as it comes across a bit...baity.

rayvy··on Nginx to Be Acquired by F5 Networks
Gonna just chime in and mention Yahoo for Hadoop (yes I know Big Table was Google), and Zookeeper. Great tech started at Yahoo, but they didn’t (unlike today) make too much of a fuss/self-pat-on-the-back about it
rayvy··on Ask HN: How do I find early startups in LA to get a job?
Welcome to LA! (Well, when you get here)

Qualifier: been here for about 2.5 years and just got a new position at a startup after 2.5 years at [big_adtech_co]

1. Angelist.co for startups 2. Bultinla.com for startups (though anglelist is better IMO) 3. Startups around here are mainly looking for mid/senior as opposed to junior (in my experience), but obviously there are Jr positions out there 4. Look for recruiters (agencies), to help, plenty of agencies around here hungry for devs (obviously you’ll have to sift through the noise to find the signal here)

5. Avoid leetcode companies..at all costs

Happy hunting

rayvy··on How to pass a programming interview (2016)
I think you’ve mentioned a HUGE part of the interview process that interviewers forget: you only have 60 mins. 45 mins if you leave time for questions (which you always should). It’s an incredibly difficult task, and deserves significant effort, as opposed to just thinking “oh interviewing is easy”
rayvy··on How to pass a programming interview (2016)
This is a decent start, but then again remember you only have 60 minutes. And what might seem relatively easy to you, might not be so easy to someone with a time limit (60 mins), and pressure (trying to get a job you want).
rayvy··on Elizabeth Warren Proposes Breaking Up Tech Giants Like Amazon
By "spent more money on congress people" @psadauskas is not simply just referring to "who spent more money last year", he's implying that the foothole that a Comcast or a Verizon has in the capitol goes much further than say a Google. And that makes since right? Especially from a government's perspective. If you can be chummy with an ISP, you hardly need the help of a downstream application builder (e.g., Google).

His statement still holds

rayvy··on Thousands of New Millionaires Are About to Eat San Francisco Alive
> Most rank-and-file joining one of these cos in the last 4 years or so will be lucky to net $1-2m pre-tax

Yea I'm confused as to where all these splurge-happy millionaires the article mentions will come from. There will definitely be people well off (as you mentioned), but I'm not sure if these folks will have the money (that they want to spend) on boats, and lavish parties. It seems like a good deal of these employees will get early retirement/nest egg money, and a few execs will get a few million, while founders obviously make out the best. Not sure why that would "eat San Francisco alive".

A sensationalist headline if ever there was one {facepalm}

rayvy··on Lyft warns it may never make any money
This type of disclosure is quite literally standard in almost every type of public company financial disclosure. Surprised this made it to the HN front page
rayvy··on Ask HN: Would you sell or diversify your startup equity if you could?
> You diversify to retain or safeguard wealth, you concentrate to first create wealth.

That'll do it

rayvy··on Ask HN: Would you sell or diversify your startup equity if you could?
Funny you mention this, I was just reading [1]this article related to the quote on "putting your eggs in one basket". Conventional wisdom says "diversify". However, I'm of the belief that you'll need high risk for a high return (can't have your cake and eat it too).

rayvy··on Facebook and Telegram Are Hoping to Succeed Where Bitcoin Failed
I mean seriously though. I love how various media platforms ALWAYS talk about Bitcoin as a failure. What? But then again, they only think of “success” as some idea cut from the same cloth as current capitalist alternatives - the very alternatives bitcoin was meant to disrupt. Bitcoin is an incredible success IMO
rayvy··on Limiting Your Digital Footprints in a Surveillance State
I'll start the discussion by just pointing out how Bloomberg and the NYT absolutely love to talk about China being a surveillance state, but hardly ever talk about the surveillance state that we live in here in the US (relative to how much China bashing they do)
rayvy··on Overpaid CEOs 2019
Any more details (that you're willing to share) on this? You mentioned they're only the "Head of HR", but you say you were a core product dev (senior by the timeline you give). Did you accept underpay because you were early? I'm having a hard time wrapping my head around an 8-month "Head of HR" making out significantly better than a (first 20?) Sr Product dev (not questioning your story though).
rayvy··on JP Morgan Unveils USD-Backed Cryptocurrency for B2B Payments
Keep in mind that the EOS ecosystem extends far beyond downloading a CLI client/etc. EOS Lynx[1] is a wonderful example of a decentralized wallet that has abstracted layers away to the point where it looks/feels/acts like a "regular people" iOS app

rayvy··on JP Morgan rolls out first US bank-backed cryptocurrency to transform paymentsd
> Open standards and interoperability made public networks more useful, but now that the networks are in place, and access is ubiquitous, walled gardens can spring up and dominate MUCH faster than distributed protocols.

And personally, how do you suggest distributed protocols work to keep up with their centralized alternatives? Obviously one could build a walled garden (UI, API, Database) much quicker than its decentralized alternative.

rayvy··on JP Morgan Unveils USD-Backed Cryptocurrency for B2B Payments
I wouldn't say its so much the UX. The UX even on some crypto projects is just fine (see some EOS projects, apps, and dApps). The problem I see is that what incentive do end users have to use crypto/privacy/blockchain/whatever apps vs the centralized alternatives? Currently? None, because no one gives a damn about their privacy/data. I don't think it will be my generation (millennial) that picks this tech up, I think it will be later generations that have seen our missteps when it comes to digital privacy.
rayvy··on JP Morgan Unveils USD-Backed Cryptocurrency for B2B Payments
It's pretty well known that these BigCorp crypto/blockchain plays are just smoke and mirrors. There is no actual differential value gained here (unless as @dwiel says,they get some sort of loophole crypto tax break). It's a bit saddening to see that the tech has been picked up by the exact institution(s) that the tech was meant to combat. But if anything that just proves that there's meaning behind the concept (regardless of a f'ing coin price).

I look forward to the day where the JPM's and the like are put out of business for this sort of thing due superior, user-friendly technology.

rayvy··on Ask HN: Why companies are not using deep learning yet?

rayvy··on Asia-Pacific is home to a rise in new self-made billionaires
Agreed. If you're a regular reader of Bloomberg (I am myself), then you see that they almost fetishize abnormal wealth - constantly writing articles in regards to what the "elite", the "1%", the "ultra-wealthy" think/do. As someone who previously liked Bloomberg (about as much as someone can like that type of thing), the constant obsession with wealth is definitely a turn off.
rayvy··on Created a fake account and Facebook still figured out who I am. How?
Great resource, thanks
rayvy··on Created a fake account and Facebook still figured out who I am. How?
Yea definitely don't take that as me insinuating anything about ProtonVPN. However _absolutely_ take that as me saying "just because you're behind [insert VPN name], doesn't mean someone can't derive your actual IP" (however that may happen). There are companies that sell this service. Again, I specifically mention this because this is how we at [large, known ad tech company] deal with user VPN traffic
rayvy··on Created a fake account and Facebook still figured out who I am. How?
OP was probably not a very technical user, else he/she would've understood that

1. They should've deleted _all_ relevant cookies (in the browser, as well as in the browsers cookie database)

2. There are many 3rd party companies that sell data packs that derive residential IPs from VPN IPs (we use some at work). A trusted/good VPN is a must

3. They probably came via the same User Agent (didn't mention changing browsers)

IP + Cookie + User Agent = Fingerprint (not a good one, but will work for Facebook's needs)

rayvy··on Snapchat weighs what was once unthinkable: permanent snaps
Yea as I can't count how many times I've seen a "stories" feature open on someone's phone and asked "Oh I didn't know Snapchat had that?", only to be told that it was Instagram. Insta ate Snapchat's lunch - pretty brutally.
