Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, dehumanization of minorities, or glorification of National Socialism.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in !yurop@lemm.ee. (They're cool, you should subscribe there too!)
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)

(This list may get expanded when necessary.)

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the mods: @federalreverse@feddit.org, @poVoq@slrpnk.net, or @anzo@programming.dev.

Humm, this will probably mean that the EU will need to look into if we need to setup a European mainframe manufacturer.

I am talking AS400/iSeries type stuff.

MasterCard and VISA process a huge number of transactions per second, and there can't be any risk of loosing a transaction in progress, so you need an extremely stable central processing node with very high redundancy.

At the moment I believe that only IBM and Fujistu makes mainframes these days, IBM is American which has now shown to not be an ideal long term trading partner, Fujistu is Japanese, with a strong presence in Europe, but they made the UK Post Office computer system, which makes me want to stay, far, far, far away from them.

Either one, whoever we pick will make it easy to get the system going, but to migrate away will be a nightmare.

I wonder if we could build something on open hardware like Risc-V, this make me wonder is Risc-V would even be suitable for this application

Lmao someone would be very incompetent to actually propose the idea to create a mainframe system to do this

It would be so stupid , it would be ancient slow and hard to maintain

Everything this century that's new is cloud, distributed, HA, real time, event driven, and fast low latency

Mainframe only has some of those features, plus really ancient legacy and other stuff that makes it not perform as well in certain areas

What?

Mainframes are not slow?

You do know that VISA handles a their transactions on mainframes?

I do

I mean slow in terms of innovation, which they stagnate on

But also performance actually

Their TCP\IP stack is one such consequence. It doesn't have any of the massive changes that happened in the last few decades that have optimized performance

Open source stacks picked those up immediately. Windows, and other older platforms still use a much slower and more poorly designed stack

That's one such example. Plenty of others

It's not that they can't solve problems. They can.

Steam engines can solve everything too. But they are not the best at every task and these days it's hard to find anything that couldn't be beaten otherwise

Mostly these systems ONLY exist because of legacy

It is why none of the big compute players have touched any of that in decades. Because it is dead technology and a dead end
