Learn when a refi saves money and how target-date funds work, including fees and when to pick a later fund year. What exactly is a target-date fund, and when should you move your date? How do you know if now is a good time to refinance a house? Hosts Sean Pyles and Elizabeth Ayoola discuss mortgage refinancing and target-date funds to help you understand how to quantify savings on a refi and how to set (and adjust) an age-appropriate retirement glide path. To kick off the episode, NerdWallet senior news writer Anna Helhoski joins with mortgages and student loans writer Kate Wood and mortgage reporter Holden Lewis to break down why refis are spiking even without fresh Federal Reserve cuts, who’s most likely to benefit right now, and how markets (not just the Fed) drive daily mortgage rate moves. They begin with a discussion of rate-and-term vs. cash-out refinancing, with tips and tricks on calculating your breakeven point, using the ~0.75 percentage-point rule-of-thumb for potential savings, and factoring in 2% to 6% closing costs and how long you’ll stay put. Then, investing Nerd June Sham joins Sean and Elizabeth to discuss target-date funds. They discuss how glide paths work (to vs. through retirement), when to push your target year if you’ll work longer, and how fees compare with index funds/ETFs, plus contribution frameworks (10% to 15% of income vs. the “80% replacement” rule) and why many hands-off investors value auto-rebalancing despite higher expense ratios. A listener case study (age 35, 2055 fund) highlights how to revisit your target date in the decade before retirement, how to read a fund’s glide path, and why staying invested and consistent often matters more than chasing perfect timing.

Don't Add Meetings/Committees To Your Change Control Process, Add Autotmation 9:05

More meetings, more committees, more reviews isn't going to deliver more reliable network changes. While a formalized process and policies for network changes is important, you hit a point of very diminishing returns: Doubling your meetings or committees or reviews isn't going to halve your error rate. It just adds friction to the process.…

Test Driven Deployment 11:02

33 weeks yang lalu11:02

11:02

In the software development world, they have a concept called "test driven development", whereby code is tested (unit tests, integration tests) before committing to the main branch and before deployment. We can take that concept and use it in the networking world, and to some extent we are, but there's more to go. The tools haven't quite caught up with the concepts, however, and I discuss this on this episode.…

In this episode, I talk about what CI/CD is for networking automation as well as the general idea for what is in the developer world. And more importantly, I talk about how most organizations probably don't need full CI/CD, they can get a lot of benefits from network automation by adopting three practices (that are part of CI/CD, but alone aren't CI/CD): Configuration generation Automated config deployment Automated post-deployment testing…

There's marketing terms, and then there's words that accurately describe a new way of doing things.

Incremental Configuration Change versus Total Configuration Replacement 7:34

2 years yang lalu7:34

7:34

One of the things we think about as network automators is the concept of incremental change versus total configuration replacement. Traditionally all our changes have been incremental. From the day a switch/router comes online, it's little change after little change. In this episode I talk about how this changes from incremental changes to total configuration replacement when working with most types of automation.…

APIs: Open or Na? 7:01

2 years yang lalu7:01

7:01

In this episode I talk quickly about whether APIs should be standardized. Pretty much all APIs are open in that the vendors allow anyone to access them and the specifications on how to interact with them are public. But using NX-API from Cisco and eAPI from Arista means using two different sets of commands to do that same thing. Projects like OpenConfig/gNMI are meant to provide a single way to configure parameters no matter the devices through a single data model. While this is useful, in the data center it's not so much a problem we tend to have. Working with one API is OK, since data center networks are typically built using only one vendor.…
