After social engineering fraud, the real question is not “did the client mess up?” It is: could the bank have broken the clients "hypnosis" before the transaction went through?

Ghostty is the terminal Claude Code deserves: native splits, a drop down quick terminal, and desktop notifications forwarded by default.

Also why Powerlevel10k silently breaks Claude Code, plus tmux and bootstrap scripts.

I must give credit where it is due,@CapitecBankSA and @SADHomeAffairs have outdone themselves... It took me less than 10min to apply for my first Smart ID card, this is including the waiting time in the queue. You have just simplified an onerous task that causes so much anxiety in people's lives.

How do manage technologists if you don’t know anything about technology? The honest answer is in the conclusion. Don’t.

Script 1: finds where your provisioned IOPS exceed what your instance can consume.
Script 2: finds where your actual workload is already approaching that ceiling. You need both.

@Thush_Mcobothi @CapitecBankSA @Uber hiya, my son had this... its an uber subscription. They make it very easy for you to accidentally press it and very hard to remove it. You need to reinstall uber and then find the subscription section and unsubscribe to it... hope this helps? Lots of people get caught with this..

@De_Real_Noriega @capitec Hi 👋... i work at capitec. There was a bug in the IOS version of the app, for some phones it would cause connectivity issues. This has been fixed in the latest update to app store. Please update your app...

[Andrew James Baker @andrewbaker007]

@Lindelo_Lee @CapitecBankSA Great suggestion ... have passed this to the app team. We are working on debit orders currently and so will make sure we make this easier to understand ♥️

Massive news: #TeamHomeAffairs is proud to announce Capitec and FNB as the first banks signed up to our new digital partnership model that will expand access to Smart ID and Passport services to 100s more bank branches across urban and rural areas - and to banking apps! 🇿🇦

On 30 April 2025, the DG of Home Affairs wrote to the CEOs of ABSA, African Bank, TymeBank, Capitec, Discovery Bank, FNB, Investec, Nedbank, and Standard Bank, inviting them to join this transformative, digital-first new phase of the Department’s existing collaboration with the banking sector, which dates back more than a decade and has, until now, seen the successful delivery of Smart ID and Passport services at only 30 branches across 5 different banks.

However, that old model relied on the costly duplication of Home Affairs staff and hardware inside bank branches, and failed to take advantage of technology to dramatically expand services into all rural and urban areas where bank branches already exist - and onto banking apps.

Thanks to our commitment to digital transformation, Home Affairs is now digitalising this long-standing partnership after Capitec and FNB became the first banks to respond positively to our invitation. I reiterate the call for all other banks to similarly accept our invitation to work together to provide Smart ID and Passport services in their branches and on their digital apps.

More details will be announced when I visit both partners this week, but it is safe to say that this marks the beginning of the end for Home Affairs queues, and the start of a new digital-first era in public service delivery. Cabinet’s Medium-Term Development Plan tasks us with expanding this service to 1 000 bank branches, and we are well on our way to meeting that commitment.

Many more bank branches + banking apps = huge step towards fulfilling our pledge to use technology to deliver 𝐇𝐨𝐦𝐞 𝐀𝐟𝐟𝐚𝐢𝐫𝐬 @ 𝐡𝐨𝐦𝐞!
