I'm not particularly leaving Twitter, but I am spending a lot less time here. Most of my posts are now on @cocoaphony" target="_blank" rel="nofollow noopener">mastodon.social/@cocoaphony, and that's where I spend more of my time reading. I'll post to Twitter for things that need more reach, and I still look at Twitter every day or two.

Big-O matters, but it's often memory that's killing your performance.: cocoaphony.micro.blog/2022/12/28/big…

@Cennydavidsson I don't think it changes this much one way or another. Before you pull something into main is a very good point to stop, think about what you (singular or plural) meant to do, and re-read the changes and make sure they actually do that, and the way you really wanted.

@cocoaphony What do you think about mob programming as a replacement for PRs? My team has replaced PRs with mob programming and it works great. I don’t miss making or reviewing them at all. Today I see PRs mostly as a open source tool and not a tool for a collaborative team

@davetron5000 I configured my client to show all posts. The folks I follow, I wouldn't follow if I didn't want to see their posts. I don't hang out on the local feeds. And *still* the CWs are handy by giving me a bold subject line, and leads me to skip over stuff I'd rather skip.

Life comes at you fast. In a few weeks, my "I'm bored" muscle memory has gone from "tw\n" to "mas\n". (after "sta\n") I think this wake is premature. Things can shamble on a long time (livejournal). But still, Mastodon has already replaced this for me. Took 2-3 weeks.

@cocoafrog Now that I've taken the trouble to make a custom instrument, I probably wouldn't go back. But if templates can let me filter signposts and HTTP requests tracks to just the pieces I want, I would save some time in the future.

@cocoafrog But question: What really got me started on this road was that I couldn't find a way to save a template that showed Signposts for a specific subsystem. It always had the general "os signposts" instrument, and after running, I had to drill down to my piece. Can templates do that?

Any custom Instruments experts out there? Maybe this is just a limitation in Instruments to keep it faster? stackoverflow.com/questions/7446…

@cocoafrog Fairly well; there are some states that are very short, so nothing is visible, but that's fine; they're very short states. The states I mostly care about are roughly of similar length and represent large chunks of the request, so when zoomed to the request, their bars are long.

@cocoaphony I see! In my experience it’s difficult to get a zoom level that shows multiple real-world intervals with readable labels as the length just differs too much so often an interval is too small to show its full label. Worse with longer labels. But it sounds like it works for you?

@cocoafrog My Instrument has tracks for the entire request time, time in each state (sequential), time spent in each activity (overlapping), HTTP requests, and total network traffic. They're all built-in tools; I just want to organize them in ways that best tell the story, even to non-devs.

@cocoafrog I've found that even with my current builtin-based solution, I screenshot and share the plot a lot (often to folks who are not Apple devs). Having the numbers on it would make that nicer, keeping the screenshot small and clear.

@_saagarjha @davedelong Yeah, that was the answer, at least with out writing a custom modeler, which I may consider at some point, but not today. Thanks. twitter.com/cocoaphony/sta…

@davedelong @cocoaphony Unfortunately custom Instruments are not really my area of expertise but from a quick skim of your question I think the answer is “you can’t do this”

@icanzilb @aligatr Bah. No fun at all. I'm considering Apple's suggestion of writing a custom modeler, which is more work, but then I can do whatever I want. (That said, for the moment, I'm going to just accept that the duration is in the label and the detail table.)

@rtfeldman A good proxy is the discount banks are offering in order to sell the loans they made. Reports of up to 40% discounts. bloomberg.com/news/articles/… Normally they're sold at very close to par (see washingtonpost.com/business/buyou….)

Context: at least in my bubble, it seems to be very popular to predict Twitter's demise in the next few years. I'm curious what actual bookmakers (whose real money is on the line) think the odds are.

Twitter is now a private company, but I assume there are ways to place actual-dollar bets on its future (based on various measurable metrics). I'm not someone who typically bets on things; does anyone know of a site which does that?

@FakeUnicode Any chance you have thoughts on this question? It's an interesting one, and maybe you have an answer better than my comment. stackoverflow.com/questions/7440…
