cobookman··on Introducing E2, new cost-optimized general purpose VMs for Google Compute Engine
However n1 and other instance classes have different sku pricing for custom vs predefined pricing.

E.g. n1 predefined machine bills $0.031611 / vCPU hour. Whereas a custom sized n1 machine is $0.033174 / vCPU hour

OP didn’t mention scale. Not all websites can be run on a single VM/node. Many can though
cobookman··on AI Dungeon 2 costing over $10k/day to run on GCS/Colab
I like how google did employee travel. They calculated a cap = 2/3 * historical employee data + 1/3 * current cost of business flight.

Obviously for common routes such as Sf to la, nyc to sf...etc they hard coded values.

for every $1 under the cap you received 50cent to use on a future travel plan over the calculated cap.

You could fly economy on an international flight saving money, then bank 50% of savings to buy a first class ticket some other time.

This created a negative feedback loop keeping travel costs in check.

Shouldn’t this be free egress as traffic is straight to a google product/ colab server or is this being downloaded in the browser?

Also cost was before cdn was enabled. This kind of traffic generally costs fractions of a cent per GiB after signing a contract with negotiation.

“”” Egress to Google products (such as YouTube, Maps, Drive), whether from a VM in Google Cloud with an external IP address or an internal IP address No charge “””

cobookman··on SpaceX working on fix for Starlink satellites so they don’t disrupt astronomy
It’s not that hard to get in contact.

If you cared you could LinkedIn message a SpaceX employee. Tweet at Elon Musk. Connected with nyt or other media who’d love to run such a story.

...etc

cobookman··on The Great Cannon has been deployed again
The "Final Solution" wasn't started at first.

As WW2 progressed the Nazis attempted to ship the jews elsewhere. Sadly countries refused to accept these refugees.

Nazis then started to pile up Jews into Ghettos. Note that these Ghettos are almost identical to the Uyghur's current situation.

As the Ghettos started to fill up, the Nazis needed a plan on what to do as the ghettos started to reach capacity. Their decision is known as the "Final Solution" or death camps.

cobookman··on What Happens if SAT Scores Consider Adversity?
Socioeconomic mobility doesn’t happen overnight.

Maybe the poor kid goes to a trade school moving up from poor to upper middle class.

The kid of said person would have a better start...repeat the cycle and after just 2-3 generations you have a Harvard/Stanford graduate

This is how many Jews and Asians moved up from being broke poor

cobookman··on The California DMV Is Selling Drivers’ Personal Information
"Statewide property tax revenues are estimated to increase 6 percent in 2018-19 and 6.8 percent in 2019-20" [1]

National average for property tax revenue growth is ~4% YoY [2].

TLDR, California sees a bigger Property tax revenue growth then the national average.

cobookman··on Save .org
Has the broader group thought about just buying their own tld?

With a better governance model.

cobookman··on Save .org
Not sure I agree. If FF & Chrome both supported it...it'd be in effect in < 5 years total.

Just look how quickly DoH is being rolled out, or Google's QUIC.

Realistically if Google, Mozilla, Cloudflare, Apple, Microsoft, and a few others agree that this move is bad, and wanted to stand up a new .org TLD...they could, and I don't believe it'd be illegal (IANAL).

There's something called defense in depth.

Even with ES deployed in an environment with proper network firewall rules...etc, I'd still want some sort of authentication/RBAC

Was thinking the same thing. Sounds expensive to repair. Leading to higher insurance premiums

I think you mean .01%. The 1% maybe have 1-10million of savings.

cobookman··on Nearly 1 in 5 Millennial Renters Expect to Rent Forever in Some Metros
30year fixed mortgage rate of say 3.5% is only ~1-2% higher than the rate of inflation.

The cost of owning the house is really just interest + hoa + taxes + upkeep. You'll get your principal back out when you sell.

Over a long enough time period, the yearly home ownership costs will be less than renting.

Owning even in SF can still be a better financial decision than renting. There's a lot of tax advantages that you get by owning a home as well.

E.g take this place: https://www.redfin.com/CA/San-Francisco/201-Sansome-St-94104.... Costs about 5.4k/month. Removing principal & tax rebate its likely costing you ~4-4.5K/month.

Somewhat equivalent rental is 3.3k/month. https://sfbay.craigslist.org/sfc/apa/d/san-francisco-916-pac...

Cost of owning is ~1k/month more expensive. However you've locked in your mortgage for 30 years. Likely after 7-10 years the place you were owning will end up cheaper than renting on a monthly cost basis.

cobookman··on The Google Squeeze
Startups can disrupt because the major public companies need to show growth for w-street. If there's no growth then the ask is on profits, which cause the company to start gutting teams.

meanwhile a startup can focus on building a great product, sometimes while not needing to be profitable.

Amazon.com took advantage of this, with Jeff Bezos famous quote of, "Your margin is my opportunity".

cobookman··on YouTube says it has ‘no obligation’ to host anyone’s video
Google also gets the ability to leverage wasted search assets for YT. YT's video long tail is very low IOPs workload.

Search on the other hand is high IOPs.

As you scale out your HDD storage fleet its great to have the benefit of putting a Low IOPs high storage with a High IOPs low storage.

cobookman··on Mark Twain playing with electricity in Nikola Tesla's lab in 1894 (2013)
1894 was just 125 years ago.

just in 125 years how far we've come technologically...it's crazy.

Makes one wonder how drastic the technology landscape might be 125 years from today.

cobookman··on SpaceX’s Starlink Satellite Internet Was Tested by the US Air Force
Ah if they could do Ground->Sat->Sat->Ground. You could always have the Sat->Ground communication over the USA.

In that setup, to jam the signal would require equipment between the USA<->Sat link (difficult), Sat<->Sat (even more difficult), or Plane->Sat (very difficult)

cobookman··on SpaceX’s Starlink Satellite Internet Was Tested by the US Air Force
Getting 610 Mibps of data connectivity to/from a Fighter Jet is likely game changing.

Starlink connectivity is from the jet to a satellite back to a ground station, making jamming the signal much more difficult from Jet to ground. I assume the starlink satellites can bounce the signal from one another as well.

cobookman··on Tesla’s new Solar Roof costs less than a new roof plus solar panels
Not just rich people. Anyone who pays taxes. Its just a tax write off. That's it.

There's lots of other tax write offs.

In California you can get solar installed for free if you are low income.

cobookman··on California’s new law bans schools from starting before 8am
I've read multiple studies that the biggest influence in a kids success in school is their parents involvement.

Don't make the assumption that throwing more money at teachers will improve our schools. Zuckerberg tried that with little success, as have many before him.

I'd rather a focus on ensuring every kid has a healthy meal at the table. A support group who's invested in tbe individual kids success. A family that encourages and supports during the best and worst of times.

Arguably the "advantage" well to-do middle class families get.

Video footage can be misleading. Different Video perspective and knowledge of events unfolding before the incident is necessary to accurately convey what happened.

Yet Java is still a defacto choice even today.

Arguably minimal fuss & stable. Java code written today will still run without change in 5 years. Can't say the same of other languages.

What other language would you recommend for a large eng organization of 1000+ ppl?

cobookman··on A multithreaded fork of Redis that is faster
Happens more often than you think with larger tech companies. Especially if one has hot keys.

However yeah, 99% of all deployments could get by with SQLite/MySQL/Postgres performance amounts.

cobookman··on Single malt Scotch whisky targeted by United States tariffs
WTO authorized the tariffs. This started way before trump. Read the article before blaming trump as sole cause
cobookman··on Single malt Scotch whisky targeted by United States tariffs
“The US first filed the case in 2004, arguing that cheap European loans for Airbus amounted to illegal state subsidies.“

“The US was given the go-ahead to impose tariffs on $7.5bn (£6.1bn) of goods it imports from the EU following a World Trade Organisation (WTO) ruling on Wednesday.”

The WTO imposed the tariffs against the EU due to a recent ruling.
