Here is a direct follow-up on this, now showing how to implement #GapJunctions in a network of #spiking #neurons (#SNN) using the #NESTsimulator. We simulate a network of 500 inhibitory neurons with gap junctions and analyze the effects on #synchrony and #oscillations. The code is also available on GitHub. Feel free to modify and expand upon it 🤗

#Banking #Outage Leaves Customers Without Account Access
Updated: May 2, 2025 By Robert Farrington
Excerpt:
"Banking Grinds To A Halt
"#Fiserv supplies the infrastructure behind many major financial institutions’ digital platforms. When its systems fail, the effects cascade quickly across the financial ecosystem.
"Banks affected include major players such as #Ally, #BankOfAmerica, #TDBank, #CapitalOne, #Synchrony, and #CitizensBank, as well as #RegionalBanks and local institutions like #NorthwestBank, #SunflowerBank, and #FarmersNationalBank in Ohio. #CreditUnions such as Navy Federal. Even money transfer service #Zelle appears to be impacted.
"Customers have reported a range of issues: locked accounts, unavailable balances, non-functioning transfers, and missed direct deposits.
"One IT staffer at a bank impacted by the outage shared on Reddit, 'It's been a nightmare. ACH files, Zelle, BillPay, and more have all been impacted.'
"Fiserv has not confirmed what the cause of the incident is. According to reports, the outage allegedly appears to have originated from problems with its core processing software (DNA) and related services like Nautilus (document and content management) and Payment Exchange (real-time transfers).
"While some functionality has returned for select services, many banks are still experiencing intermittent issues as of Friday afternoon.
"We reached out to Fiserv for comment but as of publication had not heard back. As of now, Fiserv has not released a public timeline for full restoration or details of the cause of the incident.
"This incident is more than just an inconvenience - it highlights how fragile the digital banking experience can be when so many institutions rely on a single vendor.
"Fiserv supports everything from transaction processing to statement delivery. When one system fails, it's not just a front-end website that goes dark. Payments don’t go through. Payroll deposits don’t arrive. Consumers lose access to their money."

@daringfireball How does this jibe with last year’s rumored #AppleCard switch from #GoldmanSachs' #MasterCard to #AmEx? https://DaringFireball.net/linked/2023/11/28/apple-goldman-breakup. (The other rumored partner was #Synchrony.)
Another possibility might be #Barclays; last month, #Goldman was supposedly in talks to transfer its #GeneralMotors card program there: https://WSJ.com/finance/goldman-sachs-general-motors-credit-card-barclays-226d2b02
(Barclays had a #Visa with #Apple Rewards card in the 2010s.)
