teej··on Google Is Turning Off the Works-with-Nest API
Maybe I spend too much time on HN, but I’ve literally never seen someone take Google’s side in these situations.
teej··on Launch HN: Prometheus (YC W19) – Remove CO2 from Air and Turn It into Gasoline
I don't have anything new to add, other than to say - this is a very well written startup pitch. I'm in awe of how clearly you've laid out the opportunity.
teej··on Update Regarding Add-Ons in Firefox
Not available on all clients, notably mobile.
teej··on Update Regarding Add-Ons in Firefox
Poor communication with zero accountability. A few hours could be 2, it could be 12.

“I (name the individual accountable) will give you an update at 12:00 PT (name a time) as an update to this post (name the communication channel) with the current status and latest information on this issue (don’t promise time to resolution, just time to info).”

Simple, clear, concrete, and unambiguous. I had hoped that Firefox had better communication procedures in the event of global-impact P1 issues.

teej··on Show HN: Faast.js – Serverless Batch Computing Made Simple
To serve as a data point, I effectively built an in-house version of this a few years ago built on top of AWS Lambda, all in Python. The "entry point" code or orchestration code was hosted normally on an EC2 instance. More specifically we were using Airflow, so our Airflow server would kick off a Python program that would then orchestrate a couple thousand Lambdas.
teej··on Personal Blog Analytics – Which Numbers Really Matter
How many folks am I exposing to Google Analytics that weren't before, if I added GA to my blog? I would be shocked if it was anything other than 0.
teej··on Apple Q2 Results
EPS beat estimates by 4%, $2.46 vs $2.36.
teej··on Topics in Advanced Data Structures [pdf]
Check out CRDTs - https://en.wikipedia.org/wiki/Conflict-free_replicated_data_...
teej··on Stop Memsetting Structures
Code is read many times more than it is written. If someone scrutinizes code for clear intent, I don’t think that should be considered a “pet peeve” or some quirk to be explained away.
teej··on Can Uber ever make money?
Authors who write for the Economist are anonymous, so there’s little incentive for making a bold call because there’s no payoff for being right.
teej··on Changes to Models S and X allow them to travel longer without larger batteries
You go on the website, click a couple boxes, and it tells you a price. You pay what you see on the website. How is that more confusing than a regular dealership?
teej··on Changes to Models S and X allow them to travel longer without larger batteries
I mean sure. But my gas vehicle is purely recreational, it gets a few hundred miles a year at most. I really enjoy teaching myself car maintenance and repair with it. Being an 80s car, it’s super roomy in the engine area and easy to work on.

No one is dying because I own and drive this car today. Someone might’ve died mining the lithium for my Tesla however.

This is all to say that your comment is reductive.

teej··on Unveiling the first-ever image of a black hole [video]
Different target audiences for a science YouTube channel and a scientific findings press conference.
teej··on A majority of consumers do not expect Google to track their activities
In this case it’s just poor survey question design.
teej··on How Kirkland Signature Powers Costco's Success
Everything you’ve claimed about Amazon applies to traditional retailers.
teej··on First Recorded Usage of “Hacker” (2008)
Woah, I knew illegal cab driving in Baltimore was called “hacking” but never considered the term had old roots. Turns out it all comes from the use of Hackney horses in the 19th century. https://en.wikipedia.org/wiki/Illegal_taxicab_operation
teej··on Launch HN: Bottomless (YC W19) – Coffee Restocked with a Smart Scale
Every office with a kitchen and a coffee maker in the world needs to deal with reordering supplies. This doesn't seem massively overpriced nor massively over-engineered. It's basically a scale that auto-presses a dash button for you.
teej··on PagerDuty S-1
Super quick napkin math on YC's investment. Many of these assumptions will be wrong.

    YC investment: $120,000 [0]
    YC shares: 1,050,000 [1]
    PD market cap: $1.3 billion [2]
    PD share price: $20.23
    YC investment value: $21.25 million
    YC ROI: 175x
This is a ~4x return on the S10 batch. In that same batch you have Stripe, which looks like it could be a 3000x+ return for YC.

Notes

[0] - This could be less, I don't remember the dates YC started messing with this.

[1] - The 3 founders hold 13,670,067 shares, or 91% of 15M shares. I assume YC has 7% of 15M.

[2] - I assume their Sep 2018 raise valuation as the price. I'm not confident the public will value this the same.

teej··on PagerDuty S-1
The Facebook advertising spend is most likely remarketing, not post/page promotion.
teej··on PagerDuty S-1
Half the growth in G&A expenses is due to their one-time donation to the Tides Foundation. If you back this out their expenses growth here is in line with everything else.
teej··on PagerDuty S-1
> If we fail to offer high-quality support, our business and reputation could suffer.

I don't know how common this is in S-1 filings but it stuck out to me. Support is often viewed as a cost center, I love that PagerDuty makes it such a high priority.

Edit: After some research, it turns out this is common. Docusign, Dropbox, Okta, Zuora, and MongoDB all have this statement exactly or similar.

teej··on College admissions scandal fallout: Stanford students sue UCLA, USC and Yale
Given that some of the bad actors worked for the universities, specifically athletic staff taking bribes, I think it’s not crazy to sue them.
teej··on Rudder issue that plagued the Boeing 737 throughout the 1990s
This format is a known use case and results in some of Imgur’s most interesting content. Imgurian missfilipina feeds her village’s kids for free every Sunday using donations from the Imgur community and shares her stories like so - https://imgur.com/gallery/nFoh5Bn

Human interest stories are the most common posts to use the format but educational stuff like this is definitely seen too.

teej··on Python Data Science Handbook: Full Text in Jupyter Notebooks
Yep, Jupyter notebooks have an execution API, you can find more of it here - https://nbconvert.readthedocs.io/en/latest/execute_api.html. Hosted notebooks as a service is a growing area of investment and those services presumably use this API.
teej··on Lyft Files S-1
The founders (theoretically) created $20B in value and you think $90M is sufficient compensation?

$90M is definitely enough to be more than comfortable the rest of your life. But a $5B payout would have meant they could start a VC firm, invest in the next several generations of startups, partially self-fund something ambitious like a Space-X, start funded non-profits, etc.

teej··on Perlara (YC W16) is shutting down
I felt that this was notable because of how real Ethan’s sentiments felt to me. It’s the exact opposite of an “incredible journey” non-answer to why a company is shutting its doors.
teej··on Leading with Wikipedia: A brand proposal for 2030
I think "needs adjustment" is reductive. Wikipedia could easily 10x pageviews and article count over the next 20 years. If Wikipedia doesn't grow content, coverage, and quality they could become irrelevant. Thinking donations should just go towards keeping the lights on doesn't sit right with me. An endowment that keeps Wikipedia running forever may very well need to be over $1 billion.

It turns out, the folks who planned out the endowment were very thoughtful. Check out this great read on the motivations, challenges, and plans of the endowment. https://meta.wikimedia.org/wiki/Endowment_Essay

teej··on Leading with Wikipedia: A brand proposal for 2030
A 4% withdrawal rate has a non-zero failure rate over 30 years, let alone in perpetuity. I would say they are no where close to being completely self sustaining. Also, using math calculated for personal retirement (The Trinity Study) is not appropriate for a trust/endowment/etc. Different risk tolerance, different investment strategy, different goals.

On top of that, assuming they will have zero effective cost increases is wrong. There is so much growth left in content and users. How much has Wikipedia grown in the last five years? How well do they cover non English languages? What if they had the same size article base in English as every other language? What if every internet connected user could use Wikipedia?

Saying we could freeze Wikipedia costs in 2019 based on $90M in the bank is shortsighted.

The page on The Wikimedia Endowment is actually quite interesting if you're into finance and investing - https://meta.wikimedia.org/wiki/Wikimedia_Endowment.
