Matthew #60: The New Creation (Matthew 28:1-15) Rob Woodrum (7/26/26) I’ve said many times before how much I love the Gospel accounts of the resurrection of Jesus. Critics will often point out all the discrepancies we find in them and declare the whole story as untrustworthy because of them. But it’s precisely because of those discrepancies that I find them so compelling! The narrative carries the…

Matthew #59: The Curse Removed (Matthew 27:32-66) Rob Woodrum (7/19/26) Download It’s amazing to me how much the crucifixion of one Middle Eastern man two millennia in the past has persistently and relentlessly invaded the imagination of humans right up until this present day.

Matthew #56: Tasting The Tree Of Life (Matthew 26:17-30) Janelle Greene (6/28/26) When I was in college, one of my professors led an activity that has stayed with me ever since. He said the word “apple” and asked us to write down as many descriptive words as we could. We wrote things like fruit and tree. Then he showed us a picture of an apple, and our list grew with words like red, round, and…

Matthew #54: Identifying With The Insignificant (Matthew 25:31-46) Janelle Greene (6/14/26) Download I once had a job where I wasn’t entirely sure what I was supposed to be doing. Every time my boss walked into the room, I suddenly felt the need to look busy. The problem was that I wasn’t even sure whether what I was doing was close to what was actually expected of me.

Matthew #53: The Risk of Grace (Matthew 25:14-30) Rob Woodrum (6/7/26) This week we’ll be reading a very familiar parable – what is often called “The Parable of the Talents”, in Matthew 25:14-30. As you read this story, remember that parables aren’t meant to be exact representations of God’s kingdom in all the details. Jesus said it is “like” this sort of thing.

_2025-05-29 · Posts on jub0bs.com_

TL;DR ¶ Go has now standardised iterators. Iterators are powerful. Being functions under the hood, iterators can be closures. The classification of iterators suggested by the documentation is ambiguous. Dividing iterators into two categories, &ldquo;pure&rdquo; and &ldquo;impure&rdquo;, seems to me preferrable. Whether iterators should be designed as &ldquo;pure&rdquo; whenever possible is…

TL;DR ¶ Some of the wisdom contained in Josh Bloch&rsquo;s Effective Java book is relevant to Go. panic and recover are best reserved for exceptional circumstances. Reliance on panic and recover can noticeably slow down execution, incurs heap allocations, and precludes inlining. Internal handling of failure cases via panic and recover is tolerable and sometimes beneficial. Abusing Java exceptions…
