The biggest reason is that you may also have other consumers than just Clickhouse.

Sure, but the article doesn’t talk about that, it seemed to be focused on CH alone, in which case async insert is much fewer technical tokens.

If you need to ensure that you have super durable writes, you can consider, but I really think it’s not something you need to reach for at first glance


I'm in my 40s and run my own company. We deliver a data platform, our customers can choose between our self-hosted solution or run it on AWS/Azure for 10x higher cost.

TrackerFF sounds like someone on the left trying to defend the wealth tax. As a Norwegian who believes in freedom and the right for anyone to start their own business, I think the wealth tax is one of the most toxic taxes ever introduced. In practice, it makes Norwegian-owned companies about 30% less competitive than foreign-owned ones.

It’s sold as a “tax on the rich,” but in reality it’s a 2.1% annual tax on businesses. The companies have to cover these costs, and the result is that everyone — rich or poor — ends up paying for it. The only winner here is the state, which wastes the money on useless projects and subsidies.

It gets even dumber: businesses that invest in emergency preparedness — like storing gravel or materials for war or disaster scenarios — actually get punished by the wealth tax. Imagine paying 2.1% tax every year on a gravel pile. No, this is not a joke: link: https://www.dn.no/innlegg/beredskap/sikkerhetspolitikk/formu...

The consequences are clear: more than half of the 400 wealthiest people in Norway have already left the country. There’s no risk capital left for startups, and outside the oil and gas sector, businesses are struggling. Plenty of smart young engineers fresh out of university can’t find work, and hiring of junior software developers has basically stopped.

When we talk about taxes, we should be talking about incentives and motivation. If you tax people so hard that they lose the drive to work and create, then you’ve got a real problem.

If I had the chance, I’d move to Sweden or Switzerland immediately. But I can’t, because I’ve got a family to take care of here.


> The only winner here is the state, which wastes the money on useless projects and subsidies.

They should use that to reduce other taxes instead. Especially income taxes.

> If you tax people so hard that they lose the drive to work and create

That a bigger problem for income taxes. If the top marginal rate is over 40% people will prefer chilling out instead of working hard for the next promotion.

> more than half of the 400 wealthiest people in Norway have already left the country

Did they take their money too? And their factories and land and patents and other assets? Does it matter that they're not physically present in the country?

> There’s no risk capital left for startups

Was Norway previously known for having a lot of capital for startups? I thought Europe was generally bad for startup funding.

> hiring of junior software developers has basically stopped

You've described the entire world in 2025.


>Did they take their money too? And their factories and land and patents and other assets? Does it matter that they're not physically present in the country?

The better question is the impact on future investment. Once a factory is in place, it's a sunk cost and it won't make sense to move it unless the political situation is dire. The same can't be said for investments that haven't been made yet.

> I thought Europe was generally bad for startup funding.

I wonder why that'd be the case...


> The same can't be said for investments that haven't been made yet.

We can debate counterfactuals all day long. People invest when there are profits to be made and refrain when there aren't. Everything else is bullshit.

> I wonder why that'd be the case...

Definitely not wealth taxes because most European countries don't have them. It might be because they don't have the world's reserve currency. Or the million other reasons commentators and economists have written about elsewhere.


>We can debate counterfactuals all day long.

It's not really a counterfactual. My point was that deployed capital is less subject to flight, so using that as a measure for a policy's impact is incomplete and short sighted.

>People invest when there are profits to be made and refrain when there aren't. Everything else is bullshit.

This is also incomplete. People also seek the highest returns. That's why the magnificent 7 tech companies (which happen to be all American) have seen their valuations skyrocket, whereas the appetite for Volkswagen is tepid, despite it turning a profit. That's not to say there's no investment in Europe, but based on startup funding and IPOs, it's pretty clear that the US is the favored place to invest.

>Definitely not wealth taxes because most European countries don't have them.

My point is that europe is generally business-hostile. Wealth taxes is only one of the factors. There's also high taxes and onerous regulations.


> There's also high taxes

This is correct, I called out high income taxes as a problem in my original post. There's no point in working harder when more than half the gain is taken away.

Wealth taxes != income taxes.

> onerous regulations

When I wrote "the million other reasons" - this is one of them.


The negative impact of wealth taxes is vastly over-stated.

Obviously the impact depends on the level of taxation, but it is instructive to compare it with inflation. Typical wealth taxes are in the region of 1% per year; a 1% (additional) annual rate of inflation would have the same impact on wealth as the tax and not be considered disastrous for any business except those with very marginal profitability.


>Typical wealth taxes are in the region of 1% per year; a 1% (additional) annual rate of inflation would have the same impact on wealth as the tax

Or to put it another way: a 50% rise in the "normal" level of inflation (assuming 2% target that most countries target). Moreover this is a bad comparison because most rich people don't keep their wealth in cash, they invest it which mostly shields it from inflation. You end up overstating the current costs that capital owners are paying.


All assets are denominated in currency, so there exists no "shield" from inflation, except perhaps government-issued bonds that guarantee a return above inflation. Most so-called shields against inflation are investments that yield more than the rate of inflation.

The reason I used the comparison between wealth tax and inflation is to illustrate that modest wealth taxes in the order of 1% are not more onerous than many other influences on wealth.


> All assets are denominated in currency

False.

All assets can be valued in currency, but most are not denominated in currency (and even more are not denominated in whichever specific currency it is that you are trying to hedge against inflation in.) Debt instruments are usually denominated in some currency, but stocks are a claim on a particular share of the assets of a corporation at dissolution, not denominated in a particular currency.

A stock of a physical commodity is denominated in the physical commodity, not a currency.


You are correct.

Inflation affects the value of all assets whose value is frequently traded using currency (which is most of stock markets, property, etc). To argue otherwise would be to deny the seriously negative impact high inflation can have on all aspects of the economy.

There are assets whose value is mostly not financial, e.g. physical, social, intellectual, or otherwise. These retain their value despite inflation.

Nevertheless, I aimed to show that a modest 1% tax is not onerous compared to other impacts on accumulated wealth.


> Inflation affects the value of all assets whose value is frequently traded using currency (which is most of stock markets, property, etc).

Affects them all, sure, but it doesn't affect them all in the same way, even on a broad qualitative level.


Mattermost is open source, but the licensing is complex and full of bullshit. It is not a community driven project. Once you have installed the self hosted solution, you get a user interface that asks you to upgrade to the enterprise edition in every corner and menu.

A self hosted version is better than nothing though.


The last 15 years, servers has gone from 3x memory channels to 12x, while desktop still only have 2x memory channels. It is by far the biggest bottleneck today.


15 years ago a server CPU had twice as many cores as a desktop CPU. Today a server CPU has about eight times as many cores.


Probably by using partitioning.


I love Debian, but it does have some weaknesses. For example with virtualization, when you enable SR-IOV, apparmor goes bananas. With AlmaLinux + SELinux there are no problems. I use both Debian and AlmaLinux on my servers, and with that combo I feel I get the best of the best. But I think AlmaLinux is more polished and that SELinux is superior to apparmor.


Anyone happen to have a good primer on these? Have been around a decade or two but I know almost nothing about them.


If you have many beans that does IO, startup will be slower. For example, just removing sql/database initialization can shave off a second.


Before I knew about Keycloak, I need to figure out how to use Spring Boot to authenticate via Azure Entra Id. I could't use Spring Boot Security OAuth2 as I couldn't figure out how to bind Entra ID groups to roles in Spring Boot. I saw a great video from Okta where they broke down all details down to each http request (don't remember the link to the video), and then implement each http request/redirects to Entra ID. Finally I got the token and could then use the Graph API to get group memberships for binding a Spring Boot role.

I still used Spring Sessions though, where a successfull authed user got a new Spring Session. The reason was that I liked the idea of having beans with session scope, for example where each user/role has access to a specific database schema.
