You're talking about a subset of ASCII then. Unicode is supposed to support different languages and advanced typography, for which those characters are necessary. You can't write e.g. Arabic or Hebrew without those "unnecessary" invisible characters.
if you write كلب which is an arabic word written right to left in the middle of an english sentence, you want to preserve the order of the characters in the stream for computer processing purposes. meaning the chararacter ك must come before the ل and after the e and the space with respect to the memory layout. whereas when displayed, it must be inverted to be legible. the solution is to have an invisible character that indicates a switch in text direction. if you were wondering, the situation where you want to write text in a foreign language within your text is very common outside english speaking countries.
Look I'm writing sdrawkcab (amazingly, I did it without using Unicode!). Layout is the job of your text formatting program. It's easy to fix a text editor to support right-to-left text entry.
The switch in text direction has resulted in malicious code injection attacks, as the reversed text becomes invisible. I had to change my compiler to reject those Unicode characters for that reason. It can be used in other cases to have hidden, malicious text.
Have you checked your SQL code for invisible backwards text that injects malware?
Most people using Slack, Teams etc. and especially those making purchase decisions have no idea what XMPP is and what it's capable of. Heck, even Facebook used to federate XMPP until they decided to go proprietary. Not in the interest of their users, but because it makes the most money for its shareholders.
You got me wondering, so I checked to see how much Anthropic's bribed Trump so far. According to Dario, Trump has been soliciting bribes, but they refused to pay, and the contract "renegotiation" is retribution:
"Amodei claimed that tensions between his company and the Trump administration stem partly from the firm’s refusal to financially support Trump and its approach to AI regulation and safety issues."
Sales tax is actually very different beacuse it is usually either cumulative and added to each part of the chain, or only the last one; whereas VAT is deducted in all but the last part of the chain.
Yea, the idea is that the VAT effectively taxes the added value in each step of the value chain because there's a limit to how much you can charge for an item or service. E. g. a 25 % VAT does not necessarily mean the goods become 25 % more expensive; most of those 25 % would have been profit for the reseller, intermediates and manufacturer if it were not for the VAT. Perhaps a little contra-intuitively, a high VAT keeps prices down and business efficient because every intemediate is indirectly taxed even though the VAT is only charged to the final consumer.
Used to be, but they're very complicated to operate compared to more modern alternatives and have just gotten more and more bloated over the years. Also require a bunch of different applications for different parts of the stack in order to do the same basic stuff as e.g. Meilisearch, Manticore or Typesense.
Sure, I've managed both clusters and single node deployments in production until 2025 when I changed jobs. Elastic definitely does have its strengths, but they're increasingly enterprise-oriented and appear not to care a lot about open source deployments. At one point Elastic itself had a severe regression in an irreverible patch update (!?) which took weeks to fix, forcing us to recover from backup and recreate the index. The documentation is or has been ambigious and self-contradicting on a lot of points. The Debian Elastic Enterprise Search package upgrade script was incomplete, so there's a significant manual process for updating the index even for patch updates. The interfaces between the different components of the ELK stack are incoherent and there's literally a thousand ways to configure them. Default setups have changed a lot over the years, leading to incoherent documentation. You really need to be an expert at Elastic in order to run it well – or pay handsomely for the service. It's simply too complicated and costly for what it is, compared to more recent alternatives.
