(Jun 8, 2022)
Tuesday night's Friday Night Coding Zoom has hooked me. This is the beginning of the result of that hook.
(Jun 3, 2022)
Some thoughts after another pleasant conversation with Colin Hammond of ScopeMaster.
(Jun 2, 2022)
If in fact I'm done, for a while at least, with the dungeon program, what shall I do and write about. Your input welcome.
(May 27, 2022)
I was asked what I tell people to do that I don't do myself. The answer may surprise you.
(May 24, 2022)
We should have it. What should we do when we haven't?.
(May 20, 2022)
Estimation and a tiny bit of code. ScopeMaster took up my challenge.
(May 18, 2022)
I don't like estimates in this world. Perhaps you do. If so, and you're so inclined, pick up this challenge. I'll tell you everything I know to help you.
(May 17, 2022)
This morning, I plan to write about COSMIC Function Points, Agile Practices, Civility, and Kindness. I can't wait to find out what I have to say.
(Apr 13, 2022)
The experiment i did yesterday deserves a bit of commentary. Something to think about.
(Mar 17, 2022)
Here, some thoughts raised by yesterday's Agile Alliance Zoom thing.
(Mar 14, 2022)
You'd think that software developers would realize that they are prone to error. Yet we are often more opinionated than we probably should be. Here's my opinion on that.
(Feb 27, 2022)
In which: Our intrepid author attempts to find some use for the FP library he has been toiling on for over four hours.
(Feb 26, 2022)
Today, for your delectation, I offer: the Library Trap! (Update: I looked at XSet2.)
(Feb 25, 2022)
Let's see if we can find a decent way to provide filter, map, reduce functions in Codea Lua.
(Feb 24, 2022)
Kent Beck is writing about 'tidying'. It's a whole patch of delicious strawberries, and I highly recommend them.
(Feb 24, 2022)
Yesterday's search for strawberries in the XST patch discovered problems. I want to at least double check what we did. TL;DR: It all works. Odd morning.
(Feb 23, 2022)
We're taught to 'make it work; make it right; make it fast'. We're taught that if it's hard to test, it's not right. Let's explore. TL;DR: No strawberry here?
(Feb 19, 2022)
Can we make our programming life immediately easier with this one simple trick? The answer may surprise you.
(Feb 15, 2022)
One 'reason' why folx don't want to learn technical practices seems to be that they expect no benefit. Sometimes that's more about futility than actual benefit.
(Feb 12, 2022)
Some developers show little or no interest in learning practices that could make their lives better. I'd like to understand that.
(Feb 11, 2022)
I don't know whether this is good or bad, but it's an interesting trick.
(Feb 10, 2022)
Wandering off. Spinning down. Fading out. My projects here have a habit of that. What does that say about me, about you, and about our work? And krill? Really?
(Feb 9, 2022)
In my thinking about Strawberries, I'm wondering what issues folks have with Scrum, good or bad. Please tell me. I'll mention some ways here.
(Feb 8, 2022)
There are signs and portents. What are they telling us? Is this death--or is it perhaps a rebirth?
(Feb 3, 2022)
I'm taking a couple of on-line comments as writing prompts today. Let's see what we get.
(Feb 1, 2022)
Today I learned a new term. Maybe better/worse than 'Dark Scrum'. (TL;DR: If it isn't joyful, we're doing it wrong.)
(Jan 29, 2022)
Agile Software Development is about people working together. For that to happen, it helps to be kind, respectful, and helpful. Let's talk about that.
(Jan 28, 2022)
I'm pressing forward with the Lispy thing, but I have some concerns. I find it difficult to think about but I think I have an angle. (Spoiler: It's a wrap!)
(Jan 25, 2022)
TDD is too big a lump to be a good strawberry. Today I'm playing with TDD to try to find a bite-sized goodie. I expect not to accomplish that.
(Jan 24, 2022)
Technical Practices, Craft, Excellence, Improvement, Ease, Joy. What ARE you talking about??
(Jan 21, 2022)
A Twitter exchange yesterday and today has given me today's topic. I love it when not having a plan comes together. (Hm. Societal impact is similar ...)
(Jan 20, 2022)
Let's consider the implications of small-step development on our three shadow views of the program. (Includes Sarlacc.)
(Jan 19, 2022)
Yes, short feedback cycles are good. But is the trick of the trade 'small', rather than 'short'? The answer will not surprise you.
(Jan 18, 2022)
Working software is at the core of success with agile methods. Let's remind ourselves about that.
(Jan 17, 2022)
GeePaw Hill is workin on an idea. I urged him to publish his thoughts because I knew it would help him to make things concrete. Also I wanted to comment here.
(Jan 17, 2022)
I wasn't really planning to write about Sudoku again, but here we are.
(Jan 15, 2022)
I know what you're thinking: 'Is this four rules or only one?' Well, to tell you the truth, in all this excitement, I kind of lost track myself. You've got to ask yourself one question: 'Can I use this?' Well, can you?
(Jan 14, 2022)
We're here to replace raspberry jam with strawberry jam. We need those delicious nodules of flavor and value.
(Jan 13, 2022)
It's not the method. It's not the framework. It's your unique assemblage of innumerable small things that work together toward success. And some larger things: the people.
(Jan 12, 2022)
It's Wednesday. At last night's Friday Zoom Ensemble, we talked about Jam. I am inspired to put down some thoughts. Bottom line: On-line strawberry, not raspberry. (Updated, more links.
(Jan 11, 2022)
Just a bit more playing with the Lispy Calculator to while away a few minutes in the afternoon.
(Jan 11, 2022)
Thoughts and observations. Stuff and nonsense.
(Jan 10, 2022)
I'm going to push forward with this LISP / Scheme dialect. I'll begin by explaining why, and why not.
(Jan 9, 2022)
It's still the weekend, so I'm going to follow Peter Norvig's Python LISP Implementation a while and see where it takes me.
(Jan 8, 2022)
It's my weekend and I'll try if I want to. You could try too if it happened to you. Spoiler: This takes a very weird turn. Final line: Your move, Bill!
(Jan 7, 2022)
I guess there's nothing for it but to figure out how to rewrite, i.e. refactor, a set operation based on the existence of helper structures. But how? I have ideas but are any of them any good?
(Jan 6, 2022)
Bill Wake is trying to get me to think in terms of trees. I don't want to, but he does have some good ideas. Thanks, Bill!
(Jan 5, 2022)
Today I plan to experiment with creating some form of expressions that might be optimized. I expect to stumble a lot. Come along, point, and laugh.
(Jan 4, 2022)
No, not smiles and frowns. Algebra. At this moment I don't think much code will be done today. Feel cute, might delete later.
(Jan 3, 2022)
It's 6 AM and I have an idea. This could be very good or very bad.
(Jan 2, 2022)
I don't love the interface for adding functions into an XSet. And I want to add them 'one level in'. Will hilarity ensue? Probably not, but something will happen.
(Jan 1, 2022)
Some HNY thoughts, and more on the function as an element idea. Joy, philosophy, code. What's not to like?
(Dec 31, 2021)
I was thinking before I got up about median and mode. Then I had a truly marvelous idea.
(Dec 30, 2021)
I want Lua tables to be more useful as XSets. There's a hard way. But the current design also offers an easy way. (The answer will surprise you. It surprised me.)
(Dec 29, 2021)
I'm on a path to make ordinary tables behave like XSets. But first, I have to figure out how this thing actually works! Much musing, then some code.
(Dec 28, 2021)
I have in mind small things for today, starting with an interesting and confusing mistake left over from yesterday.
(Dec 27, 2021)
No, I'm not hearing voices. But the code does tell us things, just like any working material. We need to learn to listen. Today, we listen and the result is good.
(Dec 26, 2021)
A look at the code. Maybe a bit more on stats. P.S. I learn something and ditch almost all the code I wrote this morning.
(Dec 25, 2021)
It's Christmas, I'm waiting for the household to wake up, and I enjoy what I'm doing. Perfect holiday so far!
(Dec 24, 2021)
I didn't do the best possible thing in this morning's XST article. Here's what I think about that.
(Dec 24, 2021)
Today I plan to get grouping and summing working. Who knows, it might happen. If not, there's always tomorrow or my birthday.
(Dec 23, 2021)
Let's think about what the current drafts of summing and grouping tell us about our system. Then code (anyway).
(Dec 22, 2021)
Today, rather than make any deep progress, I plan to work on something I consider interesting, sums, averages, and grouping. I promise to publish this even if it explodes. (It doesn't, quite.)
(Dec 21, 2021)
Transformations, optimizations, and the relationship between OO and XST. Got some thinking to do. You get to watch, if you're tough enough. At least a tiny bit of code.
(Dec 20, 2021)
Step by step, inch by inch, slowly we turn long searches into more direct accesses.
(Dec 18, 2021)
I don't want to get stuck in a never-ending series of new setops: there won't be much learning there. Where's the beef?
(Dec 17, 2021)
I'm sure a lot of you have been saying 'Yes, but what about tuples?', or 'Why XST anyway?'. Today, we address those fascinating concerns.
(Dec 16, 2021)
Let's work on those new operations a bit.
(Dec 16, 2021)
Short morning today. I have a tentative plan for indexes. I'll scribble some sets. Might code.
(Dec 15, 2021)
Last night's Zoom Ensemble netted me a few ideas. I'll start exploring those today. Hilarity or perhaps something good will ensue. I can't wait to find out.
(Dec 14, 2021)
Further reading leads me to think about design, and design motivation. Castles in the air. Or underground. Good stuff happens.
(Dec 13, 2021)
In conversation with Bill Wake and with the Internet, I have an idea for something to try. And I'm just about ready to assess where we are and where we should go.
(Dec 12, 2021)
I'm not sure whether this will be useful, but Bill Wake gets the credit if it is.
(Dec 11, 2021)
Bill Wake was trying to hammer an idea into my head. I must think about that. And I have a small idea of my own.
(Dec 10, 2021)
Time to work on the actual restrict operator for CSV, since the pattern-maker experiment was a success.
(Dec 9, 2021)
There's no way around it, I've got to work on the fast restrict today. Might not finish. We'll see.
(Dec 8, 2021)
Getting started with CSV data. And reporting a conversation.
(Dec 7, 2021)
Reflection leads me to focus a bit more on set operations, and less on internal methods. Does this call for a new layer? Also: real technical debt! Updated with idea from Carl Manaster!
(Dec 6, 2021)
I'm going to try to create pipelines using coroutines. I think they may make for a more expressive interface. I turn out to be partially right.
(Dec 6, 2021)
How do you design a thing like this, Brain? Same as everything else? Or not?
(Dec 5, 2021)
I was puzzling over an issue with 'union' and gained an insight that either I've never had, or that I had lost. Whee!
(Dec 3, 2021)
I found the easy way to build an iterator in Lua, so we'll do that and see whether it improves the code as much as I think it will.
(Dec 2, 2021)
I think I'm going to start on restrict today. There are some issues around atoms.
(Dec 1, 2021)
Last night I understood how to do something with XST that I've not in the past been able to do. So let's talk about why XST is interesting and what one might do with it.
(Nov 30, 2021)
I have a random idea about the data structure for sets, so thought I'd give it a try.
(Nov 30, 2021)
Save me, I'm thinking about Extended Set Theory again.
(Nov 12, 2021)
Just because I think I should do SOMETHING, I think I'll improve how CodeaUnit displays results on the screen.
(Nov 10, 2021)
I'm going to try to build a 'fluid interface' feature for Codea's graphical style capability. Why? I don't know.
(Nov 9, 2021)
Let's improve CodeaUnit a bit. But first, what's the deal with iOS shortcuts? An odd report on an odd morning.
(Nov 8, 2021)
Driven by some Slack chatter, I've been thinking about feedback. How does that fit into life, and into this little program?
(Nov 4, 2021)
Some refactoring, and some thoughts on a Twitter thread. And an odd surprise: the code says No.
(Nov 3, 2021)
Rules, rules. TDD rules, Beck Rules, OK. And a cat.
(Nov 2, 2021)
I'm just not up for going back into the Dung mines. Gonna put plain function detection into the stats instead. Also, random subtweeting. Also bear bites man.
(Nov 1, 2021)
At last, I get to apply Dave's scrolling thing. It's simple, and obvious, and I never thought of it. And a couple of stories of a great programmer.
(Oct 31, 2021)
This morning, I plan to add detailed method reporting to the full report. I am expecting no real trouble but have recognized a mismatch.
(Oct 30, 2021)
Let's get some output up in this baby. I plan to steal two good ideas while I do this.
(Oct 28, 2021)
I wonder what we could do about comments. They're tricky.
(Oct 27, 2021)
"If this is his idea of fun, he must be a laugh riot at parties." -- A Reader
(Oct 25, 2021)
Backward? Or forward? Which was it?
(Oct 24, 2021)
We continue working on our little 'Making App', because it's kind of fun. Today, I foresee a 'major refactoring'.
(Oct 23, 2021)
Let's do methods, and try to drive out some objects.
(Oct 21, 2021)
In the interest of variety, let's do some work for the makers here. Let's see how we can collect some interesting statistics from Codea programs.
(Oct 15, 2021)
What's the deal with Jira? Is it a bad thing, or the worst thing?
(Oct 13, 2021)
We were thinking about words for code. Let's consider these. New! Improved! Now with more words!
(Oct 10, 2021)
Today, I'm going to try a fun exercise to demonstrate Codea's translate, scale, and rotate.
(Sep 7, 2021)
Two ways of doing a thing appeared on the Codea forum today. I'd like to see whether we can transform the one into the other in small steps.
(Sep 7, 2021)
Another in my continued attempts to come to terms with what Scrum is rather than what it could (and should?) be.
(Sep 4, 2021)
Satire? Idiocy? Monkeys? Why not all three?
(Aug 25, 2021)
Again today, I take my writing prompt from GeePaw. I have a good purpose in mind. (Added: Dammit. I didn't expect to end up here.)
(Aug 23, 2021)
Is it useless marketing BS? Certainly there are issues. [CW: language, systemic racism/sexism]
(Aug 22, 2021)
Events in a few worlds lead me to write a few words about how we treat each other.
(Aug 15, 2021)
When someone shows you who they are, believe them the first time. -- Maya Angelou
(Aug 10, 2021)
I've had a reply from the Chief Product Owner of the Scrum Alliance.
(Jul 28, 2021)
I think that today I'm going to write about joy. I have no idea where this goes. Walk with me ...
(Jul 19, 2021)
Jeff Patton writes about the importance of outcomes. Yes, and ...
(Jul 17, 2021)
I've think I've figured out the disconnect between my view of the Scrum Developer priorities, and those of the Refactoring Team who created the new CSD track.
(Jul 16, 2021)
Responses from Scrum officials to my recent Scrum articles here and on more private slacks have not been favorable. I think I'll sum up and move on for now.
(Jul 13, 2021)
I've chosen a large windmill at which one might tilt. Could we, of good heart and great skill and courage, fix Scrum? If so, should we?
(Jul 10, 2021)
The End Scrum Now site, a bit of a rant, raises important issues. Let's explore some of them.
(Jul 5, 2021)
Herewith, some remarks pro-Scrum, and a reminder that Scrum is not as good for developers as it might be. Even some advice to developers.
(Jul 5, 2021)
On June 19th, I sent this email to the CPO of the Scrum Alliance. I have had no reply. In a second article today I will offer some related ideas.
(Jul 2, 2021)
A week ago, I posted a Scrum-related survey. Today, the results of that survey, and my comments.
(Jun 24, 2021)
Scrum asks for an Increment every Sprint. Of all the Scrum rules, this one is most important for developer success and survival.
(Jun 18, 2021)
A few(?) more thoughts on the battle between Scrum and Software Development. A review of some past thoughts, and some of today's.
(Jun 17, 2021)
The Scrum Alliance mission? Let's talk about that. Fail better.
(Jun 15, 2021)
As often happens, this article didn't go where I expected. I hope you like where it went.
(Jun 1, 2021)
What are you doing, Ron, how do you do it, and most of all, WHY?
(May 6, 2021)
I was going to move back into the dungeon today, but realized I wanted to talk about what I learned doing the ominoes exercise. Here goes ...
(May 5, 2021)
It is of course necessary to display yesterday's polyominoes, for our viewing pleasure.
(May 4, 2021)
The Zoom Ensemble folks have been playing with polyominoes. I can't resist embarrassing myself by trying them.
(Apr 11, 2021)
Alistair found some ancient estimate for a KWIC program and challenged folks to implement it. I'm picking up the challenge.
(Apr 6, 2021)
Every time these organizations stamp out a new ScrumMaster, there are programmers somewhere whose lives will be made worse.
(Jan 15, 2021)
Some thoughts on the world as I see it today, in 2021, from my privileged vantage point as an old white guy in the USA.
(Oct 28, 2020)
Today, some code review. No big plans. We'll see what we see. I expect to mention Beck's Four Rules.
(Oct 27, 2020)
We'll look at using invader count as a flag to start a new rack. I don't promise to change it.
(Oct 26, 2020)
I don't feel very bright this morning. Let's see if I can prove it.
(Oct 23, 2020)
I have an idea and I can't wait to try it out. Niagara Falls.
(Oct 23, 2020)
Today's plan: Code review, and targets of opportunity. Short morning, just one new class.
(Oct 22, 2020)
Displaying two player score. Beyond that, we'll see.
(Oct 21, 2020)
Attract mode needs to be turned back on. Maybe we should show both players' scores. What about those buttons?
(Oct 20, 2020)
Let's do more on the two-player game mode. We're probably getting to the hard part.
(Oct 19, 2020)
It's time to start on the two-player option. I have ideas but not precisely a plan.
(Oct 18, 2020)
A lesson from history, a surprise refactoring, and, apparently, a sermon.
(Oct 16, 2020)
Not really, but the saucer is looking to score.
(Oct 9, 2020)
Users observe the need for more racks of invaders. That's going to get ... interesting. Also Game Over if they reach bottom.
(Oct 8, 2020)
I've convinced myself that a global would be a better way to handle constants than the singleton. Kill your darlings.
(Oct 7, 2020)
Users have detected a problem. Users, do you hear me? Users!
(Oct 6, 2020)
Improving zombie behavior. Sound adjustments. Maybe more. Maybe less.
(Oct 5, 2020)
Let's take a look at a simple attract mode. Zombies!
(Oct 4, 2020)
More with Singletons. And distractions. And no singletons.
(Oct 3, 2020)
Improving our Singleton and using the idea elsewhere.
(Oct 2, 2020)
There's no reason to think that I'm smarter today than I was yesterday, but I am a bit more experienced.
(Oct 1, 2020)
Touch to Start has me thinking that attract mode might be within reach. Things go Very Wrong.
(Sep 30, 2020)
Saucer Scoring, then whatever makes sense to me at the time.
(Sep 28, 2020)
Another day of improv. Let's see what looks worth doing. (Wow, a factory object!)
(Sep 26, 2020)
What shall we do today? I honestly don't know.
(Sep 26, 2020)
Remarks on a Twitter comment from Jez Higgins.
(Sep 25, 2020)
Another defect. I'm starting to feel ... afraid. That's not a good sign.
(Sep 24, 2020)
This isn't Houston, but we definitely have a problem. And it's not a new one. And I'm tired of it.
(Sep 23, 2020)
Things we might do. And I'm thinking about conditionals. The next trick may surprise you.
(Sep 22, 2020)
I have an idea. Let's find out if it's a good idea.
(Sep 21, 2020)
Maybe some tuning. Do we need more start-up settings? Should the test results disappear? What about a FireControl object?
(Sep 19, 2020)
The world is burning, and I'm really just trying to ignore reality, but in addition, I've made a mistake. Another mistake, that is.
(Sep 18, 2020)
If nothing else, you have to admire me for getting over 100 articles out of ancient video games. Let's do another today.
(Sep 18, 2020)
A couple of interesting articles crossed my virtual desk yesterday. Links and some reflection within.
(Sep 17, 2020)
Better scaling, then more with the saucer, I guess. Plus whatever opportunities we spot.
(Sep 16, 2020)
More with the saucer, that's my plan.
(Sep 15, 2020)
I know the voices in my head aren't real, but they're sure ticked off at me for the past few days of messing up.
(Sep 14, 2020)
Well this goes entirely not as planned. Double Arrgh.
(Sep 14, 2020)
In which our intrepid author makes a grievous error: disagreeing with Kent Beck. Or does he?
(Sep 12, 2020)
No, not space pirates all of a sudden. I released a fatal defect yesterday. What's up with that?
(Sep 11, 2020)
A couple of small changes to CodeaUnit and my CUBase template. Then let's see what we can improve about Space Invaders. (Saturday: Arrgh, a defect!)
(Sep 10, 2020)
More to do with bombs, especially targeted ones. We need some refactoring as well. The results may surprise me.
(Sep 9, 2020)
I think today we'll work on the bomb timing, and targeting the rolling bomb. Often, what I think will happen is what actually happens.
(Sep 8, 2020)
Let's continue the bomb dropping logic. Our current design can't do what's required.
(Sep 7, 2020)
Speed indicator; Bomb dropping order; Free player, maybe.
(Sep 5, 2020)
Some recovery from repo problems, some work with the clock, whatever else seems right.
(Sep 4, 2020)
The web site with sounds came back, so I'm scarfing them down and starting to install them. Should be mostly straightforward, he said. Except when my repo locked up.
(Sep 3, 2020)
If you're like me, you're wondering what space invaders eat. The answer will surprise you.
(Sep 2, 2020)
Let's damage shields from below, and try to continue small steps toward 'better', whatever we mean by that.
(Sep 1, 2020)
Let's make missiles explode, and continue improving this design.
(Aug 31, 2020)
I want to figure out why this program makes me feel bad. Then do something about it.
(Aug 27, 2020)
Some improvements. But first, a word about less technical matters, the book `x + y`, by Dr Eugenia Cheng.
(Aug 27, 2020)
A bit of planning, a bit of action.
(Aug 26, 2020)
Let's get a start on scoring. This should be easy enough. But--when is too much way too much?
(Aug 26, 2020)
I woke up this morning certain that some of my bitmap calculations were STILL off. Something has to be done.
(Aug 25, 2020)
A bit more exploding. I'm going to continue to let things get messy.
(Aug 24, 2020)
Let's do some damage
(Aug 21, 2020)
It's my ball and if I want to play with it you're not the boss of me.
(Aug 20, 2020)
One of these two things is not like the other ...
(Aug 19, 2020)
If the world isn't flat, how come these invaders keep falling off the edge?
(Aug 18, 2020)
Today we'll try to fix the collision logic to accommodate our origin changes, and to make the invaders explode.
(Aug 16, 2020)
I've moved the good iPad into the TV room and while waiting for our Sunday festivities to start, I'll set up the project's bitmap assets.
(Aug 14, 2020)
Having decided to move to CORNER mode from CENTER, we've got some work to do. I'm hoping this one isn't interesting.
(Aug 13, 2020)
Is it worse luck when Friday the 13th comes a day early? Or a near miss? Time to dig further into bombs failing to miss shields. (Added Friday: It was worse luck.)
(Aug 12, 2020)
I had no plan. Now I have a plan. Check code clarity, then work on shields. Things go ... oddly
(Aug 11, 2020)
Maybe make the invader bombs do some damage? Or what?
(Aug 10, 2020)
My plan for the day is to retrain myself by reading this code that I've not touched for two whole days, and then to see about moving things forward. My guess: invader missiles.
(Aug 7, 2020)
I think today I'll work on making the invaders march back and forth. Right now they just march forth and forth and forth ...
(Aug 6, 2020)
A friendly demo of shield damage techniques leads to an examination of an interesting coding approach. I need to figure out what I think about it.
(Aug 5, 2020)
It's 6 bloody AM and I'm programming. What's up with that?
(Aug 4, 2020)
Let's see about extending our square invaders game-like thing to be a bit more like a game.
(Aug 3, 2020)
Twelve articles and no product. What's up with that?
(Jul 30, 2020)
Adam Savage (@donttrythis) posted a marvelous video of his attempt to build a giant brass nut and bolt. It reminds me of software.
(Jul 22, 2020)
In the real game, the invaders' missiles eat away at the shields. How can we duplicate this effect?
(Jul 21, 2020)
An experiment and some planning. Then even some doing.
(Jul 20, 2020)
Learnings from the ancient scrolls. What shall we do about them?
(Jul 18, 2020)
This one is mostly for the record, if it goes as planned. I'm just going to import some more bitmaps. I recommend against reading this.
(Jul 17, 2020)
Let's see what happens if we try to refactor our little spike into something reasonable.
(Jul 16, 2020)
A bit of an idea about marching, and thoughts about spikes.
(Jul 15, 2020)
I need an idea. Representation is important.
(Jul 14, 2020)
I'm wondering how to move these invaders. Let's do an experiment.
(Jul 13, 2020)
Dave1707 from the Codea forum shows a much better approach to converting the bitmaps.
(Jul 11, 2020)
Importing Invaders. How hard could this be?
(Jul 10, 2020)
I'm having so much fun with Asteroids that I thought I'd look at the old Space Invaders game. I'm sure I'll learn something.
(Jul 9, 2020)
Let's clean up that level handling a bit.
(Jul 8, 2020)
Unfortunately, we need to take things to whole new levels. This'll be fun. (Later: not as interesting as some, but it has its moments.)
(Jul 7, 2020)
Let's get some more modernization up in this baby. I'm sure it's the only reason we aren't selling millions.
(Jul 6, 2020)
Let's see about reducing a Singleton or two, and maybe some more modern graphics.
(Jul 6, 2020)
Our marketing people have a challenging request: modernize the look of this game.
(Jul 2, 2020)
It could happen: I've figured out a good way to handle these callbacks.
(Jul 1, 2020)
We'll continue our code review, with particular attention to our tweens, especially that tricky one.
(Jun 30, 2020)
I feel like reviewing some code. What I learn? Kill your darlings.
(Jun 29, 2020)
We're nearly done here!
(Jun 29, 2020)
Some tweaks to hyperspace seem in order, but I feel that this thing is nearly done.
(Jun 27, 2020)
Enhance Hyperspace?
(Jun 26, 2020)
Perfect saucer shots and a start on hyperspace.
(Jun 25, 2020)
Let's put in some options.
(Jun 25, 2020)
Let's clean up the Aimer and look around. I think we need options.
(Jun 24, 2020)
I really want to crack missile targeting. I've made some observations.
(Jun 22, 2020)
Two things go right. One thing goes horribly wrong
(Jun 20, 2020)
Free ships. Beyond that, maybe some reorganization? No, more like confusion.
(Jun 19, 2020)
Let's finish up the small saucer, and how about testing it this time?
(Jun 18, 2020)
Ships Remaining Indicators. After that, who knows?
(Jun 17, 2020)
After some discussion of things we might do, we decide to do GAME OVER. The results will surprise you.
(Jun 16, 2020)
Run tests automatically, dribs, drabs, and oddities. Pretty calm.
(Jun 15, 2020)
Today I plan to give the saucer the ability to aim its shots. I anticipate zero trouble.
(Jun 13, 2020)
A bit of planning and a bit of doing.
(Jun 12, 2020)
Not really an answer, but just a bit of fun.
(Jun 11, 2020)
Some sound, and saucer needs to stop helping so much.
(Jun 9, 2020)
Let's do collisions. And try to TDD them.
(Jun 9, 2020)
We move saucer and ship in the direction of our new scheme, and get rid of the cloning of the collection. Also took a nice walk.
(Jun 8, 2020)
We made a number of useful changes last time. Let's harvest some value.
(Jun 8, 2020)
I'm sure my double dispatch approach will work fine. But the pattern seems simpler than that ...
(Jun 7, 2020)
Some thinking and working on collisions. Is Ron converting to London School???
(Jun 6, 2020)
I've determined that it's time to collapse some 'technical debt', in small, incremental steps.
(Jun 6, 2020)
We need to improve collision detection. I think we have to do it in one go.
(Jun 5, 2020)
I think this afternoon I'll just push a little further on the saucer. Maybe make it dangerous.
(Jun 5, 2020)
I've decoded how to draw the saucers. Let's see about making them fly. That will require some research.
(Jun 4, 2020)
Some rationale, an experiment, some learning, some protection.
(Jun 3, 2020)
We start asteroids on the edge, which gives us an edge on refactoring.
(Jun 3, 2020)
A new approach to steering. And an apology.
(Jun 1, 2020)
I found some better recordings of the Asteroids sounds. And it's time to trigger new waves.
(May 31, 2020)
Stereo, because I can.
(May 30, 2020)
Based on the 'learning' from #25, let's just make bigger buttons.
(May 30, 2020)
Today I decided to experiment with improved controls. The experiments, um, succeeded oddly.
(May 29, 2020)
New ship, new sounds, learn new tricks, amaze your friends, confuse your enemies. Apply now! UPDATED!
(May 28, 2020)
I think today we'll do waves of asteroids. And some tests.
(May 27, 2020)
I've made yet another mistake. Will the embarrassment never end?
(May 27, 2020)
I reckon it's time to kill the ship when it's hit by an asteroid. I have a clever way to do it and a direct way. Which is best?
(May 26, 2020)
I'm feeling like coding a bit this evening. So stand back.
(May 26, 2020)
Thinking about tests and refactoring. The boss wants a feature.
(May 25, 2020)
I think it's time to move more toward objects. Part of our mission is to decide what we like. And: 'No large refactorings!'
(May 25, 2020)
I thought I knew what we had to do today but I was a bit mistaken. We need more, and better thinking ... and code.
(May 24, 2020)
Just arriving 'at work' this morning, I'm thinking we'll make the Ship move. We need a safe place to land first. EDIT: Arrgh, a defect!
(May 23, 2020)
A report on last night, and a 'major' refactoring. P.S. There is no such thing as a major refactoring.
(May 22, 2020)
A quick report on a short project last night, then let's try to get something nearly playable.
(May 21, 2020)
I looked up tween and my tween example and it seems like just the thing. Let's find out.
(May 21, 2020)
First, I'm really feeling the need to improve this code. But maybe it's too soon to do good work? Plus explosions.
(May 20, 2020)
Displaying different shaped asteroids is nice, but we have an issue of size we might work on for a bit. And let's split them!
(May 20, 2020)
Having converted the 6502 asteroid shapes to Codea style, let's plug them in. This design is starting to bug me, and we'll think about that too.
(May 19, 2020)
Dave1707 offers a much better idea for the conversion of Asteroids graphics into Codea. Let's explore it.
(May 18, 2020)
I found the definitions of the asteroid shapes in DVG language. Let's draw them in Codea.
(May 17, 2020)
I spent last night decoding some graphics chip code on computerarchaeolgy.com, and I managed to draw an Asteroid in the classic style. Today, a look at what I found out. Updated: New Resource.
(May 16, 2020)
I've decided how buttons should work. It only remains to make it so.
(May 15, 2020)
To move forward with this project, the ship needs to be able to move forward. And turn. And fire ...
(May 14, 2020)
OK, Asteroids doesn't have a horizon, but today we'll start on the ship. Shouldn't be too hard: it's a triangle.
(May 13, 2020)
I needed to test some floats the other day. Let's improve CodeaUnit to help with that.
(May 13, 2020)
Today we'll clean up the code a bit. It really needs it.
(May 12, 2020)
Today I decided to draw two square asteroids at random angles. All's well that ends well, but I did get confused.
(May 11, 2020)
For something to do, and because it might be helpful to new Codea users, I'm going to implement an homage to the old Asteroids game.
(Mar 22, 2020)
Wow. Shapr 3D is neat! I wish I could use it. It's so cool I might warp my process just to fit it into my plans.
(Mar 18, 2020)
This may be the most powerful most frustrating 3D application ever created.
(Mar 17, 2020)
To create reasonable creatures or vehicles, I'd need a decent 3D object creation tool. Ideally, since this is an iPad project, an iPad app.
(Mar 11, 2020)
I am supposedly on a course to make the Orc stay within bounds of our little world. Today might be the day ...
(Mar 9, 2020)
It's probably time to work on behavior, so I want to take a bit of time to look forward at what we might do, might not do, and probably won't do.
(Mar 8, 2020)
It's Sunday. My long-suffering wife is prepping for the upcoming election. On my own, I decided to spike motion for my game creature.
(Mar 7, 2020)
I've decided a bit about the 'game' I'm writing in Codea. This should keep me off the streets for a while.
(Mar 3, 2020)
I've been reading examples and searching the web about terrain generation and I'm ready to start sharing. Brace yourself, this gets pretty random.
(Feb 28, 2020)
I feel I've got my feet firmly on the grass, dirt, and bedrock, and I can see what I'm doing. Time to become confused again.
(Feb 27, 2020)
I think I nearly have a solid place to stand: a tiny application that I understand pretty well. Today we'll clean it up and see what's next.
(Feb 25, 2020)
There's trouble, my friends, right here in river city. Is this little project serving my needs? Am I about to break through to the other side ... or to break through the ice and freeze?
(Feb 17, 2020)
We're at a fairly clean point right now. There are a couple of small topics in the code to consider, but we need to figure out a plan for what's next.
(Feb 17, 2020)
Owing to driver error, I lost all my code versions for the Orc program. We'll speak of recovery and then move on.
(Feb 11, 2020)
In response to some question on the codea.io forum, Dave1707 showed me a neat trick with text. It taught me something, and raised some questions.
(Feb 10, 2020)
Despite its great value in the hands of experienced TDDers, the uptake is slow and the practice is often hard to sustain. What's up with that?
(Feb 7, 2020)
The bird experiment worked pretty well. Now it's time to clean it up and consolidate what we've discovered.
(Feb 5, 2020)
I've made a couple of objects move, in two different ways. I figure that topic is spiked. What should I look at next? This session is gonna be rambling, I'll wager.
(Feb 4, 2020)
Today I'll build a different kind of creature, who moves differently from the Orc. The idea is to build up an understanding of where the design needs improvement in terms of flexibility or clarity.
(Feb 3, 2020)
Today I'll review the code, and think about whether to build in some object thinking. I want to ... but should I?
(Jan 31, 2020)
Last time I managed to make a fairly simple Codea Craft program draw an Orc standing on (or near) the floor. Today I plan to make him move a bit, and then to see what I've learned.
(Jan 30, 2020)
Yesterday I managed to move an Orc, by hacking a sample program. Today, let's try to do a clean version to consolidate our learning and ask ourselves some questions. Maybe even begin to answer some ...
(Jan 29, 2020)
I begin trying to make sense of Codea's ambitious and powerful Craft components.
(Jan 20, 2020)
>Alex Bunardzic has been part of a rambling Twitter thread about TDD and people who object to it. One of his concerns is that TDD proponents agree that TDD isn't always appropriate but don't say when. Let's explore that.
(Jan 18, 2020)
I tweeted this on the 18th, in response to something left frustratingly vague by one of my dear colleagues, which caused me to think more deeply about what they said.
(Jan 8, 2020)
Some folks who don't know TDD, and some folks who should know better, have been describing TDD in ways that don't match what I experience. Herewith, some thoughts.
(Jan 8, 2020)
In a Twitter conversation a week or so ago, I was asked to do a TDD video, to show how I do it. A video isn't within scope just now, but here's an article with real TDDed code in it.
(Nov 25, 2019)
Despite my concerns about experienced coaches advocating against practices that are often quite useful, there are a few things where I'd at least advise great caution.
(Sep 15, 2019)
This article expresses, in written form, the talk that Chet Hendrickson and I gave at the deliver:Agile conference.
(Sep 12, 2019)
A private note from GeePaw Hill, and a tweet from Brian Marick inspire me to mumble a bit about mindfulness and collaboration.
(Sep 10, 2019)
When I was blurting about the Increment as the most important thing, just the other day, GeePaw Hill mused about collaboration as the most important thing. Today, I'll muse on that and his notion of makers-making-made.
(Sep 5, 2019)
If you are not producing working, running, tested usable software in every single Sprint or iteration, you are not [yet] 'doing' Agile, you are not [yet] 'doing' Scrum.
(Aug 29, 2019)
A question on AgileMentoring.com triggered this little article. Perhaps repetition is the mother of something ...
(Aug 24, 2019)
Kate chats with people at the KALE Society meetup. They discuss some small issues and then one big one. Test Doubles come up. Darts are thrown.
(Aug 20, 2019)
A Twitter conversation and some reading has triggered some new, and probably some old, thoughts on estimation and the #noEstimates tag and meme.
(Aug 5, 2019)
A bit of a screed about naming, triggered by a super idea from Dan Terhorst-North.
(Jul 6, 2019)
We're here to discuss whether Agile ideas fit in with fixed-scope efforts. We'll look at Agile values, principles, frameworks, and practices. The answer is that Agile works just fine.
(May 23, 2019)
I like to say that I may have invented story points, and if I did, I'm sorry now. Let's explore my current thinking on story points. At least one of us is interested in what I think.
(Apr 19, 2019)
There was a thread on Twitter talking about Agile being anti-management. No, it's much more radical than that.
(Apr 15, 2019)
Sprints, Iterations, Cadences, Continuous Flow. Planning sessions, daily scrums, retrospectives, increment reviews. Are these all, in the end, overhead to be eliminated along the way to some Agile Nirvana?
(Feb 28, 2019)
Scrum is founded in the belief that self-organizing teams can figure out what they need. When true, this is sometimes not sufficient. And sometimes, particularly in software development, it seems not to be true.
(Feb 27, 2019)
Let's talk about what responsibility we have for those who never take a course from us, read our books or web sites, or even see our tweets. I think we have rather a lot.
(Feb 26, 2019)
I wrote this in response to some tweets from an esteemed colleague, who I think is a bit less sensitive to dangerous ideas than I'd prefer our 'thought leaders' to be.
(Feb 21, 2019)
Another little tweet-storm about estimation. I think it's useful and not as easy to use as some people think it is.
(Nov 3, 2018)
I was asked on Twitter what I meant when I said 'Simple, not easy. There's a difference.' I have no idea what I meant then, but here's what I think just now.
(Oct 26, 2018)
Are Imposition and Dark Agile both bad? Yes. Are they the same thing? No.
(Sep 26, 2018)
Some early unfocused thoughts around original XP practices and what I might say today.
(Sep 17, 2018)
I'm not going to define a new framework, and don't think I should redefine XP, as it's not my baby. But I was thinking ...
(Aug 17, 2018)
I tweeted a storm about responsibility when 'Agile' doesn't go well. Here we'll unroll it and say a few more words.
(Jul 25, 2018)
Yesterday, I tweet-improvised the following thread. I had intended to write it up later as an article on my site, and here it is. It received a number of replies and comments, and I'll address some of those here as well.
(Jul 20, 2018)
There's a lot of whinging going on about imposing 'Agile' methods and practices. These whiners just don't know how to do imposition correctly. Me either, but here's what I'd try.
(Jul 19, 2018)
People have been telling me for years that Scrum is not an Agile Software Development Framework. I should have paid more attention. It's still good stuff, though.
(Jul 11, 2018)
A discussion of my personal values in the light of way too many 'well-reasoned' but mistaken notions on diversity.
(Jul 9, 2018)
A chapter from 'Software Development, How I'd do it'.
(May 10, 2018)
The above was the title of my talk with Chet Hendrickson at deliver:Agile. I'll update this with a link to the talk when it is published. Meanwhile, here are some thoughts.
(Apr 20, 2018)
I watch The Expanse to force myself to exercise. Today this quote hit me pretty hard.
(Apr 12, 2018)
Where do we place the responsibility–surely not blame–when things don't go well on a Scrum team? Who's responsible for taking action? (A bit of something I wrote on Twitter, lightly edited.)
(Apr 6, 2018)
Just a few words about why I publish all these words, going over and over the same topics again and again, repeatedly and repetitively.
(Apr 6, 2018)
On the Agile Mentoring Slack group, Jack Caine and I were discussing what it means to be Agile. I wound up writing something like this, and wanted to share it more broadly.
(Apr 3, 2018)
I'm not finished ripping Scrum a new one, but I don't want to come off all negative. So let's talk a bit about what I'd like to see done.
(Apr 2, 2018)
We've spoken often before about the backlog. Let's get down and dirty today. Delenda est backlogus or something like that.
(Mar 29, 2018)
If your factory pollutes the river, you're supposed to clean it up. If you plant kudzu to combat erosion, you are responsible for its destruction of everything in its path. If you swallow a spider to catch the fly, and die when you swallow the horse, of course -- it's on you.
(Mar 28, 2018)
The Sprint causes serious problems in many Scrum installations. What are some ways to mitigate those problems?
(Mar 27, 2018)
Let's consider the Scrum Sprint. What's the strongest case we can make against it? It harms people, how's that for a case?
(Mar 27, 2018)
In the spirit of inquiry, fairness, and a generally bad attitude because it's raining, let's consider how strong a case we can make against Scrum. It might be fun.
(Mar 22, 2018)
These articles about hills to die on are in response to a continuing trope on Twitter and elsewhere, to the effect that X is bad, or Y is better than X, and therefore don't do X do Y. These are amusing, provocative, and rather frequently ... mistaken.
(Mar 21, 2018)
When are Sprints a good idea, when not so good? What are their values, and their costs?
(Mar 20, 2018)
Bashing of Scrum (and other methods) is a common form of Internet Entertainment, and not without reason. Some of the concerns are more accurate than others. Choose carefully which hill you want to die on. In this series we'll explore some hills.
(Jan 23, 2018)
There's a lot of noise going on on the Twitter just now, about starting with Scrum, with kanban, or with nothing. Here are some thoughts.
(Sep 8, 2017)
Responding to a mistaken TDD flowchart.
(Sep 6, 2017)
Mike (GeePaw) Hill storified about sense of urgency and an acronym RAMPS. I like what he said and will muse upon it.
(Aug 4, 2017)
I'm wondering, today, whether the Increment could be the driver for all 'Agile' software development.
(Jul 31, 2017)
Today, let's talk about cadence. Iterations, Sprints, to have them or not, that is the question.
(Jul 26, 2017)
I was asked a question about one of today's modern approaches to Agile software development. Here are some general thoughts.
(Jul 12, 2017)
An innocent email question leads me off into wildness and chaos. What's new with you?
(Jun 26, 2017)
What if I were to create a new software development framework? I'd never do that, but if I did, what might I do? Let's find out. Let's talk today about Whole Team.

Some Notes on the theme "If I were going to create a new framework, what would it be?".
(Jun 21, 2017)
A number of tweets and posts this week point out, correctly, that if we don't think about what we're doing, Scrum and Agile won't work. Apparently people need this reminder.
(Jun 12, 2017)
A couple of things passed by my Twitter last week and I'll try to comment briefly on them. For values of 'briefly'.
(Apr 24, 2017)
Based on our Scrum Gathering 2017 talk, we discuss the impact on real software development of growing focus on the 'enterprise'.

Time was, you got a spec, got browbeaten into saying you'd do it in 6 months, then got mostly left alone for 6 months. Now, they get to **** with you every ******* day!

Good frameworks are deep. Quick-entry courses sell well. It turns out they sell TOO well.

Scrum is good, when done as intended. Otherwise it can be oppressive and dangerous to developers. Let's study: Defense Against the Dark Arts of Scrum.

A twitter conversation got me thinking about the extent to which Agile ideas are intended to support small improvement, or to disrupt things.
(Jun 27, 2016)
Some interesting tweets make me wonder: if I were creating a method today, what would it be?

Over the past few days, an ancient twitter thread accidentally revived, talking about how you don't need quality code when you're just validating assumptions. What do the ants have to say about that?
(May 24, 2016)
Tozier and I did a little work on the ants experiment. Lessons are beginning to be learned.
(May 17, 2016)
Tozier posed an interesting problem today, and we decided to work on it at the coffee shop.
(Apr 21, 2016)
I found this picture of a roulette wheel. I wonder how hard it would be to make my little game use it.
(Apr 20, 2016)
Let's finish wiring up our second pass at Jim Jeffries' roulette example, and see what we can see.
(Apr 19, 2016)
I felt I owed it to myself to do Jim Jeffries' roulette exercise, this time with more tests. You won't believe what happened next. (Sorry, I have a click-bait virus.)
(Apr 18, 2016)
Jim Jeffries (no relation) proposed a TDD exercise / challenge. I took it on. The results may surprise you. (Sorry.)

Just some small thoughts bordering on rants. Something here for everyone to get mad about.

At the time of the Agile Manifesto, we all did the best we knew. Here's something I wish we had done. (Revised)

Chet and I were talking about the importance of the Increment and the Sprint Goal. Herewith, some musings.

You people could help me by doing a better job and making fewer mistaks.

One great way to remove an impediment is to replace an old idea with one that's better. Let's give that new idea a new name.
(Aug 26, 2015)
Kate and Dan estimate a new project. Or do they?
(Aug 24, 2015)
I haz one.
(Aug 24, 2015)
The Estimate-Commitment relationship stands in opposition to collaboration. It supports conflict, not teamwork.

After a lot of email and blogging, Steve McConnell and I "Came out by the same door where in we went".
(Aug 6, 2015)
Many individuals are creating new, marvelous, incredibly valuable Agile contributions. These were inspired by the Manifesto. They are not updates to the Manifesto, they're founded upon it.

In which we search for common ground and disputed ground.
(Jul 31, 2015)
Steve makes some great points. I think I'd make somewhat different ones.
(Jul 29, 2015)
If we can't build software well, all our Agile is for nothing.
(Jul 24, 2015)
A recent Twitter conversation bugged me (and bugged Clarke Ching even more). Here's why.
(Jul 22, 2015)
Privilege. No privilege. Screw it, improve your situation. Or don't. It's up to you.
(Jul 20, 2015)
OK, one more on this bowling thing: I decided I should do some tests.
(Jul 19, 2015)
Scoring bowling is Chet's and my go-to application for demonstrating pair programming and TDD. So here it is in Elixir, without either pairing or TDD. Interesting, though.

A report on building up a payroll pipeline. Twice. And still not entirely liking it.
(Jul 15, 2015)
Let's see whether we can sketch a little payroll. In Elixir. As the title suggests. Expect trouble - I do
(Jul 15, 2015)
It seems like time to experiment with something new. Will it be Elixir? Hold on, this is going to be chaotic.
(Jul 13, 2015)
Apparently the word 'estimates' is not clear. Here's what I mean and don't mean.
(Jul 11, 2015)
You keep using that word. I don't think it means what you think it means.
(Jul 9, 2015)
Slicing is easier and better than estimation for projecting done. And slicing adds value, while estimation does not!
(Jul 7, 2015)
That's all you need. You don't need no more.
(Jul 6, 2015)
A Twitter conversation got me thinking about how often teams or organizations fall away from their process, when it happens, and why.
(Jul 5, 2015)
Theory, Practice, Received Wisdom, Certification. These are not the things that make things work. Good people make things work.
(Jul 3, 2015)
Keep seeking better ways.
(Jul 2, 2015)
Deciding what kind of tests, and what tools, would be good for a payroll series, if I continue with it.

I love computers! Trying to set up Fitnesse and landing squarely on rspec.

Every minute we spend just thinking and talking, and not programming, is wasted!
(Jun 29, 2015)
Chet and I just ran an Agile Skills Workshop last week. It was great fun. We were asked for a description, and here it is.
(Jun 7, 2015)
A brief um discussion about the Increment and how it might help you change culture.
(Apr 24, 2015)
I guess today I must write about the Scrum "Definition of Done", which is neither a definition, nor done. Is it a Scrum Artifact? I'd rather not.
(Apr 23, 2015)
Someone asked about comments on this site. I don't want comments on the site, but I am happy to discuss things, so I've set up a Google Groups forum. Here's some info about the forum.
(Apr 20, 2015)
I had occasion to look at a couple of articles from 2010, and things don't seem to have changed much. Should we be concerned?
(Apr 10, 2015)
All around us, Scrum and Agile are used, misused, and abused. How should we feel about that?
(Mar 29, 2015)
For success with Scrum, we need the basics, our expertise, and to improve our culture. To improve the culture, we need the Product Increment.
(Mar 27, 2015)
Development teams need help using the product increment as a center for making lives better. I resolve to work to fix that.
(Mar 27, 2015)
We're not blaming you when we say you're doing it wrong. We're trying to help you do it right.
(Mar 27, 2015)
We need to make Scrum and Agile safe for software developers. How should we proceed? (updated)
(Mar 25, 2015)
It's not up to Scrum or "Agile" or XP to make you successful or happy. It's on you.
(Mar 25, 2015)
We don't want just a "Product Owner". We want a Product Champion!
(Mar 23, 2015)
Impediments are there to be removed, not there to be recorded for posterity. Drive them out, don't log them in.
(Mar 16, 2015)
There's not much wrong with Scrum. Or is there? It depends what the meaning of 'wrong' is.
(Mar 16, 2015)
They shipped the software, therefore what they did was best. It ain't necessarily so.
(Mar 12, 2015)
Jonathan Rasmusson wrote an interesting article. I agree. It's not about unit tests. It's about skill and understanding.
(Mar 9, 2015)
Giles Bowkett invited me to discuss another article he wrote. For some reason I'm willing to do that.
(Mar 6, 2015)
The conversion from XProgramming.com to RonJeffries.com is essentially complete. Let's look at some learnings.
(Mar 2, 2015)
Many people assert that Scrum fails often. They say it's Scrum's fault. I'm still trying to understand.
(Mar 1, 2015)
Jeff Sutherland said today that it's not done if it's not tested. You won't believe what happened next!
(Feb 24, 2015)
It is my practice to reconsider important topics. Certification certainly is such a topic. Here are today's thoughts.
(Feb 20, 2015)
Giles Bowkett has written some impassioned diatribes against Scrum on his blog. He raises some issues, which I shall try to discuss.
(Feb 8, 2015)
I was reminded by a lovely email of what happened during our SAFe training. Eliminate dependencies, don't document them or accommodate them.

Address given at the final meeting of the Agile Alliance, August 20__, by Ron Jeffries
(Jan 24, 2015)
As Tozier and I work on Scraper, I find the pairing to be quite difficult, though not unrewarding.
(Dec 8, 2014)
XProgramming will transition slowly over to ronjeffries.com. Be there or be square.
(Nov 29, 2014)
Today is a big day for people tweeting how they deplore what other people are doing. Others retweet those tweets. I think that's a fruitless behavior and suggest something different.
(Nov 22, 2014)
This is an NSFW rant regarding the whiny, mewling *bastards* who bitch, whine, and complain about Agile methods, Scrum, and similar topics.

Scrum top dogs announce combined site for Scrum definition.

XProgramming.com needs a new implementation. Want to watch?

Put makeup on your own pig, make it look as good as you can. Don't go around finding ugly imaginary pigs to stand it beside.
(Apr 2, 2014)
Recent Twitter conversations inspire me to pull out some of my concerns with SAFe and talk about them.
(Feb 27, 2014)
I recently took the SAFe SPC training. My bottom line assessment is that it will be a marketing success, organizations trying it will see improvement, and some will see great improvement. And I don't like it.
(Dec 31, 2013)
Don't buy a brand. Seek out good ideas, and apply them to your situation.
(Mar 27, 2013)
Robert Pirsig's protagonist "Phaedrus" said "Quality is what you like". We talk a lot about "value". My aim here is to suggest to you that value is what you like.

Overcoming the Estimation Obsession
(Jan 3, 2011)
Alan Shalloway blogged on "Big Change Up Front", suggesting that it's not always the best thing to do. This made me think ...
(Dec 24, 2010)
"Why don't you believe in testing?" said Lanette Creamer, the Testy Redhead. Ah, but I do. I care about what, when, and at which end of the horse.
(Dec 12, 2010)
An odd anonymous article on "LearnTFS" purports to debunk Agile by moving closer to waterfall. Interesting, but not quite right.
(Dec 10, 2010)
I've had the privilege of observing He Jinbao, a martial arts master. He doesn't hurry. Maybe we shouldn't either.
(Dec 9, 2010)
Are there places where lower quality has less negative impact? Possibly. Except maybe on your soul.
(Dec 8, 2010)
No one I know can operate at their peak performance all the time. How do we know how hard to work on quality? Same way you get to Carnegie Hall.
(Dec 7, 2010)
You can always find someone to argue for cutting quality corners to "go faster". Is it possible to waste time cleaning code? Sure. Is it possible for code to be too clean? No.
(Dec 1, 2010)
Teams often want to write "technical stories" to cover things like testing and improving the design or infrastructure. There is rarely a need to do this. Here's why.
(Nov 6, 2010)
Alan Shalloway and I were tweeting about whether Scrum could be improved because it doesn't include some damn thing or other. Scrum is working as designed. We and the Alliance need to get to work.
(Oct 31, 2010)
Chet and I will be meeting with both the new and the outgoing Managing Director of the Scrum Alliance. I asked for input on Twitter, and have received some. Here, some thoughts.
(Oct 20, 2010)
"Just tell us when you'll be done with all these requirements" is not how to guide an Agile project, be it Kanban, Scrum, or XP. Not remotely.
(Aug 27, 2010)
Some people have difficulty living up to the values and principles of the Agile Manifesto. Should we improve the Manifesto? Raise your game: we meant what we said.
(Jul 15, 2010)
"His brand is bad: my brand is good." Isn't it well past time we got over that kind of thinking? I'll take a good idea from anywhere. So should you.
(Jul 13, 2010)
Should we ease into Agile, or jump in? How fond of being eaten by bears are you?
(Jun 29, 2010)
Let's consider two "dimensions" of a project, the extent to which it adheres to "Agile" values, and the extent to which it is an effective or successful project.
(Apr 11, 2010)
There has recently been another discussion of Kanban on one of the Scrum lists. Kanban has some interesting ideas, and yet it seems to conflict with Scrum in some essential ways. The problem isn't Kanban: it's the notion of "essential ways".
(Dec 21, 2009)
Agile projects very often seem to stall out after gaining perhaps twenty-five percent of the possible benefit. Why is this? What can be done?
(Dec 16, 2009)
Incremental and iterative development processes provide frequent opportunities for teams to "Inspect and Adapt". What should we inspect? How should we adapt? Is this part of the process?
(Nov 20, 2003)
Object aficionados worldwide are concerned that the procedural bowling solution presented last time is just not robust enough. They want to see how we would make it score the frames incrementally. Frankly I haven't the slightest idea.
(Nov 18, 2003)
Here's the Bowling Game again. This time I'll take a simpler approach, along the lines I usually follow when I do a Test-Driven Development demonstration. The result is strikingly simpler than the preceding 'object-oriented' solution. What does this tell us about TDD and how to use it?
