jayp··on Why GraphQL Is the Ideal API Language for Front End Engineers
Disclaimer: My co-founder at Midtype Neel wrote that article.

I have used GraphQL for the last 2 projects I've been involved with... and definitely was a better experience for frontend engineers.

Was the last API you built REST or GraphQL? Why you pick one vs. the other?

jayp··on Self-serve first: an overlooked paradigm underlying great software companies
Not sure where this is coming from. Not my experience, but I am one data point.
jayp··on U.S. regulators approve the Long-Term Stock Exchange
I am happy for LTSE.

The article doesn't explains what makes LTSE different than NYSE? How will it actually encourage looking beyond the next quarter? Where can one learn about that?

jayp··on Pluralsight will acquire GitPrime for $170M
Congrats to the GitPrime team.

While the acquisition price is public, would love to learn more about revenue or # of customers. They must have had some serious revenue/traction to be bought for $170M.

jayp··on Don’t buy the MacBook Pros even on sale, in my opinion
I just switched back to Thinkpad X1 w/ Windows. With Linux Subsystem for Windows, it's been roughly working out. though I am currently maintaining two copies of things - one for Linux and one for Windows for lots of tooling. Not sure how to optimize here. Only been a few days. Re-learning keyboard shortcuts.

Only pain: not having iMessage on laptop.

jayp··on Ask HN: Do you use continuous deployment for your web app? How (or why not)?
One specific question is how does one resolve an issue?

One option is to automatically revert back to a commit when an issue is discovered until a fix can be applied. Does anyone use this? If so, what is your team's SCM (i.e., git) workflow?

My guess:

Not in a law-of-physics point of view, but I suppose, it is from the perspective of the entity that pays for the server.

If you can push the computation to the end point, and simply spend fewer resources (let's say, 1000x fewer resources) to coordinate the task, then, behold 1000x cost reduction!

jayp··on Exploring Property-based Testing (using Clojure)
Please let me know if there are any concerns/comments about the article.

Sharding via a Tweet Storm(TM).
jayp··on Exactly-Once Messaging in Kafka
Completely tangential: can you please invite me to lobste.rs?
jayp··on Ask HN: What's left for early startup engineers as the company grows?
A 10-year exercise window has to be extremely rare to the order of non-existing in SV startups. Maybe it's picking up stream since the article was written and I am not aware of it. Can an employee vouch for his/her employer (company) that does this? Do more recent YC companies do this?

In fact, even Quora hadn't actually implemented a 10-year exercisable window by the time (or right before the time) Sam's article was written: see comment at https://news.ycombinator.com/item?id=7610668. Note that the article simply mentions it as an idea; not as an ongoing implementation. I wonder if it is now actually implemented at Quora.

jayp··on Wit.ai (YC W14) Is Joining Facebook
Congratulations to the Wit.ai team.

I was never a user, but when I checked them out, did think their offering showed great promise. I suppose the offer from Facebook must've been too good to say no.

jayp··on Are we consistent yet? Eventual consistency of cloud object stores
Yeah, more sophisticated and challenging experiments can be had.

However, as they say, reality is relative. If the tests they ran are "realistic" in the sense that most people use the systems in the same way they tested, then it's all good.

I suppose we need to agree on what's realistic / acceptable. I would say just minimize client-server RTT and that's a good setup, which they may have.

jayp··on Are we consistent yet? Eventual consistency of cloud object stores
Thanks for the clarification and the work Andrew and you put in.
jayp··on Are we consistent yet? Eventual consistency of cloud object stores
Thanks Justin.

Ahh -- "observed instances of eventual consistency" as in "able to observe poorer than strong consistency". I was imagining it as able to eventually confirm _consistency_. However, was dumbfounded by the lack of information on delay before check.

I wonder if the experiment normalizes for the client origin. The farther the client is from the actual server, the more time it takes to do a round trip, and less chance for an observed instance of eventual consistency.

jayp··on Are we consistent yet? Eventual consistency of cloud object stores
What does it mean by "observed instances of eventual consistency"? Shouldn't it be close to 100% given enough time? The claim of zero for 100k operations is jaw dropping (and requires more evidence, or simply, a better explanation of the experiment).
jayp··on Show HN: Madrassa – Code and Design Courses Reduced to 5sec GIFs
Doesn't the name have seriously negative connotations... at least in English-language media. Until I looked it up right now, I didn't know that is a positive word in Arabic. I have always seen in portrayed negatively and associated with Islamic fundamentalism.
jayp··on Ask HN: Big company approached our stealth startup – what to do?
Have been through an acquisition before as a core/senior team employee at a startup.

The big company that acquired us didn't even ask to take a look at your code until after a deal was discussed, and intent signed, but before closing. (i.e., final due diligence... and they wanted it to scan for GPL violations, etc.). They evaluated our software/company by focusing their efforts on extensively using our software in various (stress) test scenarios prior to discussing the deal. They also asked us to add a few features on short notice to test our ability to execute.

In fact, they kept the competing implementers (read: engineers who would actually write code) away from the deep technical decisions (and they had a competing effort which they merged with us later). Most of the technical discussions were limited to the engineering director who ran the group. They took a very caution approach: they have much more to lose then us if the deal didn't went through and they did in fact end up launching the product (i.e., possibility of a failed startup suing them).

I think if it any reputable big company in the valley, they will probably follow the same protocol.

One word of caveat: you may end up working on a deal, but generally it will take a LOT of your time. So you should find out if the discussions are leading to something you want ASAP.

jayp··on YC Demo Day Session 2
On the other side of the coin, there are index funds for fixed income too. That would be a better compare against hedge fund that primarily uses fixed income assets. (For hybrid hedge funds, there are hybrid index funds too.) Once again, the 2 and 20 payment structure makes it very hard for it to beat a 0.2 fee index fund.

And as for clearly better funds like A16Z and YC now, there have many numerous that have held that crown before. Fees and fund expansion have resulted in worse results -- allowing newer players like A16Z and YC to take off.

My argument is that I don't think it's clear who'll beat the broad market (for their asset class) once the fees are taken out. I suppose we disagree about the value of high-fee managed funds (whether VC, PE, Hedge, etc.). That's fine.

Anyway, enough digression from the discussion on hand.

Good luck to the founders in making their value proposition clear. I am sure there are lots of people want to invest in hedge funds but don't have the funds to invest directly. They will find this appealing.

jayp··on YC Demo Day Session 2
Is it really irrelevant?

How do you suppose one tell which hedge fund will do better and which won't beforehand? Past performance? We know that's not a good indicator. If you can tell which hedge funds will do better in the future, you probably can tell which stocks will do better, and then why not just got it yourself without giving someone else 2 and 20?

We agree that S&P500 and hedge funds have different risk factors.

The point is that S&P500 is a lot less riskier and with better returns than an average hedge fund.

jayp··on YC Demo Day Session 2
Interesting. If Hedge funds can't event beat a vanilla S&P500 index fund, why would any one want to invest in a hedge fund?

Buffet (S&P500) is leading against hedge funds on the aforementioned long bet: http://fortune.com/2014/02/05/buffett-widens-lead-in-1-milli...

Disclaimer: I am on Buffet's side on this long bet. Management fees are the devil. I am all-in for low-fee index funds.

jayp··on Employee Equity
I think you should hit up Adam and see if he can provide you with a 9-year 9-month extension. If not, you should let Sam know so he can provide an update clarification on the article.

There is also a precedent for such type of clarification updates in YC family. YC founding partner, Jessica Livingston, provided a clarification with respects to Sabeer Bhatia of Hotmail vs. DFJ ventures based on the statements Bhatia made in an interview with her for the book "Founders at Work".

jayp··on Stripe: Marketplaces
PayPal has a lower rate for small transactions too.
jayp··on MA lost contact with MH370 at 12:40 AM. Waits until 7:30 AM to say anything
lost contact at 2:40AM, not 12:40AM. Still a long time, but the title exaggerates.
jayp··on Learn to think big
At least Gabriel is upfront about it: investing contributed a big part to the changing of his world view. Here is how a cynic may see it:

(1) Risk of time (and other things, including money) => go safe.

(2) Risk of money (only) => go big.

I am genuinely not sure[1], but it does occur to me that this could be the underlying difference in approach between an investor and a founder (more specifically: a founder still looking for his safety net.)

---

[1] To tell you the truth, I find myself leaning towards "going big" of late. But until I found something tangible, it's just an exercise in vanity.

jayp··on Ask HN: How many YC companies have African American founders?
Michael Seibel founded two YC companies: Justin.tv and Socialcam
jayp··on Employee Retention
While I agree with your premise, the didn't-take-early-offer-and-run seems doesn't provide strong enough evidence.

For a super successful startup (a la dropbox, stripe, etc.) -- why take only $50 million and leave the rest (possibly hundreds of millions) on the table? Especially with investors chewing their ears out about going for the home run. And, possibly, with an opportunity to cash out partially (a la Groupon, airbnb, etc.)

jayp··on How to build great products
Yeah, I have to agree. Looks like the author took a long time and care to formulate this thoughts. Obviously, the experience to come up with these thoughts took over 3 years as the article mentions.

This is the type of article I come to Hacker News for. Thank you for writing it.

jayp··on This 4×6 index card has all the financial advice you’ll ever need
It's barely positive if you compare the two points. However, if you have investing regularly via your 401k (etc), you also bought in during the low periods. So, your gain would be much more than just minimal positive.
jayp··on VMware introduces log analytics tool - vCenter Log Insight
I have been an engineer on the Log Insight team since prior to VMware acquisition (which happened 10 months ago -- see http://cto.vmware.com/vmware-acquires-log-insight-technology...).

To make it interesting to the Hacker News crowd, I can provide some insights into how our acquisition went -- from a small startup to launching the product at a huge company with a large sales team.

Please let me know if you have any questions, comments, etc.
