Nginx has a service mesh too. Is it any good?

Let's find out.

 1/

Most service meshes use Envoy as a proxy and for good reasons:

1. It's fully open-source
2. It can be customised on-the-fly via an API
3. It can be extended
2/

Is there a service mesh without Envoy? Of course!

The best example is @Linkerd that uses a custom proxy written in Rust.

Linkerd is smaller and more focussed but it is also slower to add features.

And now there's a new entry: @nginx
3/

But isn't Nginx one of those products not fully open-source proxies?

Yes it is, but they made an exception.

When you run the Nginx Service Mesh you can use Nginx Plus (the paid product) as a proxy for free.

Great isn't it?
4/

How does the meshwork?

There are four main components:

- The API
- SPIRE (cert authority)
- NATS (message broker)
- Nginx Plus as a proxy

Grafana, Prometheus and Zipkin are automatically installed too.
5/

Ok, but how do you run it?

You can find my step-by-step instructions on how to get the mesh running locally on minikube.

If you install the bookshop demo apps, you can inspect the mesh metrics in grafana, Prometheus, and jaeger.
6/

Now the real question, is it good?

Short answer: I don't know. More testing is required.

However, I collected some pros and cons.

Let's start with the "not so good" parts.

And now the PROs.

How does Nginx Service Mesh compare with the other meshes?

F5 reached us @Learnk8s to help you answer that question.

The common understanding of propaganda is that it is intended to brainwash the masses. Supposedly, people get exposed to the same message repeatedly and over time come to believe in whatever nonsense authoritarians want them to believe /1

And yet authoritarians often broadcast silly, unpersuasive propaganda.

Political scientist Haifeng Huang writes that the purpose of propaganda is not to brainwash people, but to instill fear in them /2


When people are bombarded with propaganda everywhere they look, they are reminded of the strength of the regime.

The vast amount of resources authoritarians spend to display their message in every corner of the public square is a costly demonstration of their power /3

In fact, the overt silliness of authoritarian propaganda is part of the point. Propaganda is designed to be silly so that people can instantly recognize it when they see it


Propaganda is intended to instill fear in people, not brainwash them.

The message is: You might not believe in pro-regime values or attitudes. But we will make sure you are too frightened to do anything about it.

"The engineers on my team just want to code. They don't want to have anything to do with product. They just want specs. What do I do?"

1/n Are you asking them do to X *and* do their "day job" as defined by their managers (and frankly your roadmap) ?

If so, start there...

2/n Do they have a reason to believe that doing X will in any way improve the quality of the product and make their lives easier? Have they ever seen X "work" ?

Show don't tell.

3/n Is there average day/week a quagmire of unnecessary meetings, wading through tech debt, struggling to get *anything* to work ... and jumping through process hoops to prove their worth?

If so...no they will not have bandwidth.

4/n How do incentives work on the engineering team? Maybe they want to help, but their "grade" is determined by something altogether different.

"I'd love to, but I am on the hook to deliver [some project] this quarter to make a good impression..."

Talk to eng management.

5/n Have they had any time to practice?

Or did they get thrown into the deep end the first time they were given a shot ... expected to brainstorm on demand, be as vocal as practiced PdMs and designers, and "participate" !

Make it safe to practice. Reasonable expectations.

🧵 @DianeLangberg wrote about NDAs in Christian environments, noting “An NDA is an agreement to hide something. In the cases I have encountered it has always been an agreement to exercise power over and hide sin.... [it is] unlike our Lord.”
1/

NDAs are traditionally “non-disclosure” - don’t talk about specific X. Often in church/ministry cases - they’re overly broad - don’t talk abt *anything* re: your employment

but also may include

“non-disparagement” - don’t say anything negative about us EVEN IF IT IS TRUE
2/

Numerous articles have described the use of NDAs in Christian environments and the conflict with principles described in the very faith supposedly being promoted. I’m linking them here then I’ll offer my 20-year lawyer and victim of silencing (gag order) take on the practice.
3/

“Silence of the sheep” (2018) from @emlybelz described how the conference of catholic bishops has now banned NDAs in abuse cases but how some churches and Christian orgs still use them without

Later in 2018, @scotmcknight discussed NDAs after the Bill Hybels sex abuse scandal, noting that often the stronger party is implicated in sin because the whole reason for the NDA is bc they know that something is wrong and they don’t want it

I am reading through reams of late-1920s communist poetry and easily my favourite title so far is: "To a Lady who Rejected a Poem about Spring as a Petit-Bourgeois Deviation"

The last lines:
"So here's my hat into the air,
Three cheers for your amazing hair,
For coal mines, and for turbines, too,
For steel, the Comintern and you!"

A not exactly graceful (though possibly satirical) title: "Lines Disassociating Myself from Yessenin and Supporting the Otherwise Unfounded Legend that I am a Foremost Proletarian Writer"

An excerpt:
"Goodbye verses of Yessenin
Goodbye literary slop-
You are not the line of Lenin
You are not the line of WAPP

Never shall I moan a
simple lyric from the heart
I'll devote my new corona
to the proletarian art"

The poet was Joseph Freeman, who published much of his revolutionary verse in the New Masses, a stylish journal of the interwar American literary Left.

Yantrodharaka Anjaneya Temple, Hampi, Karnataka.

This temple dedicated to pawanputra Hanuman, near the banks of Tungabhadra river was built by dwaita philosopher and rajguru of the Vijayanagar empire, Sri Vyasaraja around +500 years ago.


:It is only in this temple that Hanuman appears in a prayer position. In this image, Bhagwan Hanuman’s crown has been formed by his tail.12 monkeys have been carved around this amulet.


:They represent the 12 days Sri Vyasaraja prayed to Hanuman ji. Each monkey holds the tail of the monkey in front of him but is facing backward. Seed syllables have also been carved around the amulet.


:It is believed that Sri Vyasaraja used to draw a picture of lord Hanuman here on the rocks before offering prayers using charcoal and the sketch disappeared after prayers.This incidence happened for 12 days in a row until he pleaded to bhagwan to appear in front of him.


On the 12th day, Hanuman ji appeared in front of Sri Vyasaraja and blessed him. Hanuman asked Sri Vyasaraja to constrain him in a hexagonal amulet & install him in that place.

1. The major problem most startups face is marketing and the ability to carve out a niche, find and retain paying customers.

Even with a stellar developer team and a stellar product, your startup may not grow or survive without a great marketing and sales teams.

2. Start growing your audience before you’ve a product or an idea.

You should start promoting yourself and building your audience before you have a finished product or even before you have a great idea that you want to build.

3. Don’t wait to start building your audience after you’ve launched a product.

Most first-time developers actually ignore marketing.

They’re oblivious to the challenge of attracting people to take a look at something they’ve created.

4. At least until they see their first project crash and burn within hours of the launch.

There are so many times that I have seen developers spend countless hours building something, releasing it with no fanfare...

5. and only then trying to figure out how to promote it by asking marketing questions on Indie Hackers, Quora or Hacker News. Don’t make that mistake.

SRI BANASHANKARI AMMAN, BANGALORE
#bharatmandir

Located in Southern Bangalore, this is one of the most popular places of worship in Bangalore City.
Devoted to Devi Banashankari, this shrine is visited specially during Rahukala which is believed to be an unfavorable time.


Somanna Shetty, a great devotee of Devi, brought this murti from Badami’s Banshankari Amma Kshetram.
It is said that many years ago, three ladies visited this shrine and requested the pujari to conduct puja for them. Since it was the inauspicious rahu kaal, the pujari refused.


However, upon their insistence, he conducted the puja. When he returned with prasadam, the ladies vanished. This made the people believe that they were none other than the Devi herself. Since then, the people perform poojas here during the Rahukaal.
@GunduHuDuGa


People use lemons as a diya. Lemons are cut from the centre and their pulps are removed, for pouring oil in them.
It is strongly believed that Devi removes all the troubles from the life of her devotees during the Rahukala although it is considered inauspicious for any pooja.

“We don’t negotiate salaries” is a negotiation tactic.

Always. No, your company is not an exception.

A tactic I don’t appreciate at all because of how unfairly it penalizes low-leverage, junior employees, and those loyal enough not to question it, but that’s negotiation for you after all. Weaponized information asymmetry.

Listen to Aditya


And by the way, you should never be worried that an offer would be withdrawn if you politely negotiate.

I have seen this happen *extremely* rarely, mostly to women, and anyway is a giant red flag. It suggests you probably didn’t want to work there.

You wish there was no negotiating so it would all be more fair? I feel you, but it’s not happening.

Instead, negotiate hard, use your privilege, and then go and share numbers with your underrepresented and underpaid colleagues. […]
