what would be the best way to reach out to college communities? assuming the product is most useful to them.

1. Can you point any company in recent history that went through bankruptcy/auction to pay is retail investor their money back... or for that matter, most tech companies with negative net income does not pay dividend either...

2. So called, "Money" does not pay dividend... does Gold pays dividend? now on the other hand, I can lend you BTC or Gold and ask you to pay me back the principle + interest on it in BTC/Gold etc so that is that... Fiat money can yield as it can be created of thin air, no actual work required (i.e. mining for Gold or BTC)

3. Any currency, company also can be replaced by something else out there but won't why? network effect, trust and liquidity matters...

What makes it funny is they can survive everything but can’t manage to turn them upside down if they get flipped... kind or ironic....

Access to talent, capital and culture still makes SF Bay Area one of the top if not first in the list. Are there issues here? Of course, one too many.

this makes me think,

1. If history is written by the winners then how does it matter?

2. If history is written once you depart then how does it matter?

3. Finally, if leaving a legacy that important; how far one would go to write it the way they want?

does this model work?

"The electric-vehicle startup Rivian will make the platform for Lincoln's first EV. That platform will include the vehicle's motors, suspension, and battery pack."

isn't these 3 (motor, suspension and battery pack) core competency of any EV?

got it. thanks.

if apple were to be a nation state, it will be one of the top 20 trillion dollar economy... insane and amazing... https://en.wikipedia.org/wiki/Trillion_dollar_club

got it. thanks.

What happens to bandwidth saturation on the backup database/RDS host? is it unlimited? Capped? user-defined? i.e. would backup impacts the ongoing transactions/packet transfer?

VC money does not fix TAM, be it 100M or 1B. What is does; allows startup to pivot and find other areas of growth (hopefully really fast), which is not easy or guaranteed to work either. Recent examples like WeWork, Zume and many more... I must also add, sometimes not everything that one sees fits in the definition of TAM... by true definition of TAM, AirBnB and UBER would have been a lifestyle business when they were first started....

Daniel, I am no genius but if you are reading this, WashingtonPost story with your details hardly makes you anonymous.

- Daniel

- in his late 30s, but he’s 48 years old

- returned from a 10-day trip to Italy’s Amalfi Coast

- journeyed to a yoga retreat and juice cleanse in Bali

- ending a five-year marriage

- shedding 10 pounds of subcutaneous fat several years back

> Why did the VCs value these as billion dollar companies? Desperation?

1. FOMO

2. Easy Access to Capital in last decade

3. Winner takes it all culture, which causes more FOMO

But then as a VC you also have to bet future with incomplete set of data... which is not truly a science... though there are some Midas in VC... reality/statistics is only 3-5% of all investment will hit home run, 5-15% will do average and other will just fail... we would not have many of the company/services around if someone would not have taken those bets (from UBER to AirBnB and others...)

What one study, listens or believe is their choice, regardless of the medium through which one acquire that learnings (be it a professor or guru. By your argument all professor and accounts are almost always correct because?)

Also, just because something is science does not make people believe it (for the most part of our civilization earth was flat and for many global warning is hoax) Similarly, just because something is NOT science does not make people NOT believe it too.(the whole world of placebo is not science that has shown to work for many)

cheers,

You’d be surprised to hear many of these spiritual gurus. Their ideas are much more logical (if not intellectual) than an average priest (of any religion) whose learning/ideas are almost always about religion. Again, I’m not making the case for or against anyone here.

Like I said in my previous comment, One does not have to ”follow” these gurus, be it Indian or otherwise. But I also believe, one should have open mind to listen to all ideas. Eventually, What one doss with these ideas is one’s choice.

I feel you completely missed my argument here, which ended with,

Does Principal has flaws? Yes. Do they always work in good faith? No.

Simply put, What to do with information/guidance one receive is their prerogative and life/lifestyle of these people is theirs.

Should we appreciate ideas more than the people behind it? Yes. Will we ever do it? No.

Let's drill down,

Why go to gurus to listen to ideas or ideology, that you can read in books and practice at your home?

Why go to college when you can learn anything from books or by working on it (as profession or hobby)?

Why go to tax planner when you can file taxes on your own?

In World, where information is asymmetric, (and we lack time to acquire information or expertise) we need help. They are our references/guides, with assumption and hope of good faith (No fiduciary agreement)

This is classic Principal Agent Problem.

Does Principal has flaws? Yes. Do they always work in good faith? No.

Simply put, What to do with information/guidance one receive is their prerogative and life/lifestyle of these people is theirs.

Should we appreciate ideas more than the people behind it? Yes. Will we ever do it? No.

+1.

Shame is a focus on self, guilt is a focus on behavior. Shame is “I am bad.” Guilt is “I did something bad.” - Dr Brene Brown. Failure treated as a guilt may lead to learning and be fixed, but if treated as Shame may lead to depression.

basically locking will create the serializability for that document... so if there are concurrent updates on mongo side it will have to wait... also for step-1 in dual write it should be automic/two-phase between mongo and RDBMS.

you mean the result set or the query it-self? databases like oracle, mysql, postgres can already identify existing queries and hash it to re-use execution plan etc... some can even convert literals in queries into bind.. generally seeking use bind variables in your queries for re-use...

real question is, why do you need a distributed relational database? when it comes to scale (both in size, QPS, latency) existing RDBMS would just do fine for 95% use-cases. For very small use-cases where you would absolutely need distributed RDBMSs keep some good hygiene of not using DRDBMS specific features, data types etc that can lock you in for future portability/mobility...

1) start with dual-write to both the DBs for all the writes.

2) all reads from Mongo

3) in the background start data migration, one key/document at a time; transform Mongo document into RDBMS table/rows and insert... have mongo document id as primary key for main table... for every document migration/insert, lock the corresponding RDBMS row, this will ensure data consistency...

4) create code path to read from RDBMS.

5) test it in stage for different fail-case scenarios...

6) ideally, do canary type push to single server etc in prod to see if read from RDBMS seems fine (this assumes #3 is done)

actual steps may vary... but these are high-level steps....hope it helps...

It depends, what you define as database. is it only the SORs (Statement of Records) or everything from Cache, KV store to RDBMS? Let's just say everything, I believe it would be in range of 300-500 trillion queries every day.

for multi-tenancy users(=customers) there are 3 main solutions,

1) Single DB with a) dedicated table per user or b) shared table with column that identify the user 2) Dedicated Schema for every user. 3) Dedicated DB for every users.

there is no good answers and you'll find everyone have solved it differently as they scale... few biggest names i can think of my haed are SalesForce, Workday and ServiceNow

"best iPhone ever" is never an inaccurate statement, subjectively speaking (compared to previous release of iPhone), if you think about it. :-)

https://www.youtube.com/watch?v=9SexsvIO4vE internet is full of these examples.

My point is, computer with,

- more data, (historic on how to act on certain situation, live data for event i.e. sensor data, lidar/radar data, images) vs human driver who would not have access or the ability to process these.

- faster and parallel processing vs human driver

- single focus/goal (of driving from x to y safely and making appropriate decisions to achieve it) vs human driver (with "physical limitations", "emotions", "hormones" and other things that makes up "life") is more likely to be distracted...

computer with all of above advantages compared to human driver may able to make better informed decision much faster than human driver can do (and when it doesn't it's hard to know/prove if human driver would consistently make better decision every time for same situation)

having said above, I agree that tech is in its infancy and it's gonna take a decade or two to be matured and even after that human intervention just in time in some cases would be needed but for the most controlled/learned environment (which is 70-80% of total driving on day to day basis) these systems would be immensely helpful.

Yes. point about the charges would be a thing, something that should be debated...

would "use at your own risk" vindicate the company behind autonomous vehicle? or owner is responsible for his vehicle's actions? i guess never in the history, we had so much advance automations in direct hands of consumer...

As for the failure, I have reasons to disagree... if autonomous cars are working under "unsupervised learnings", my assumptions is, it most likely will makes different decisions for same scenarios based on data on hand.... so thousand's of failure events... though it may look similar may or may not end in same results... similar to how we would react when faced to some unknown situation on road... your scenario might more likely to play out for bad batch of hardware devices/sensors/lidar/camera etc in autonomous system...
