Rules (2024-08-30)
- 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.
- 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 When you post outdated/historic articles, add the year of publication to the post title.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.
- 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.
- No bigotry, sexism, racism, antisemitism, dehumanization of minorities, or glorification of National Socialism.
- 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).
- If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
- Light-hearted content, memes, and posts about your European everyday belong in !yurop@lemm.ee. (They're cool, you should subscribe there too!)
- 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.
- 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
Tech guy here. There’s no way in hell a new system would be mainframe-based. A distributed queue with delivery receipt and many nodes to process messages along with many distributed read-only DBs is the way to scale this thing. And you can be isolated form local power and connectivity issues. Tech isn’t the problem in this situation, market penetration is.
I know right!
I think this is another case where even the engineers got sold into the marketing
Because they heard three decades ago that this was the fastest best technology, and IBM sold it to them
... The reality is, these technologies nobody uses for anything new and there's a reason why. They are just too ancient and stagnating
Plus, other technologies are open and you can see how much more innovation happens when you allow that. Mainframe never had that and that's why it sat around
