Have you ever tried to do a code review on a PR that merges a large release branch or feature branch back into mainline, fixing merge conflicts? It’s not pretty. The diffs are often and easily very big, — 50k+ LOC big — have hundreds of commits, and the actual changes made by the engineer resolving the merge conflicts are virtually impossible to spot. This article covers one nifty trick I’ve been using lately in these cases that lets you....

There is no way to get Java to automatically use find out many cores are available and use them all, on AWS ECS using Docker. You have to specify how many cores you want to use via the -XX:ActiveProcessorCount option. On JDK >= 10, use the following JDK options: -XX:ActiveProcessorCount=2 On JDK >= 8, use the following JDK options: -XX:+UnlockExperimentalVMOptions -XX:ActiveProcessorCount=2 Discussion Having optimized my CPU-bound ..

It’s old, but — as the saying goes , every day someone is born who has never seen the Flintstones. I wanted to take a second to drop a link to Mozilla’s new project, Firefox Send . This service promises free, private, end-to-end encrypted, and temporary file transfers from a respected company with a stated desire to preserve its users privacy. Check out the release notes here . Also of interest, pCloud Transfer allows anonymous users t..

I want to take a moment to speak to my old readers. Maybe you forgot to remove my feed, never got around to unfollowing me on Twitter, or just stayed close and hoped that I would one day write again; regardless, I’m glad you did. What this site once was, however, somewhere for me to talk about the writer’s craft, Apple, and technology, it is no longer. Permalink.

Over the last few years — perhaps not that unusually among the nerds I know — I’ve become increasingly fascinated by the Apollo program (and early space program more generally), and been reading my way through a growing number of books and documentaries written about it. At a party this weekend I got asked for my list of Apollo book recommendations, so I decided to write them in a form I can easily share and refer to, in case it’s of intere..

A while back I wrote a post about distributing a ROS system among multiple snaps. If you want to enable some sort of add-on story, you need to have multiple snaps, and that remains the way to do it today with ROS. That approach works, but I’ll be the first to admit that it’s not terribly elegant, and we’re working on making it better. However, in my experience talking to various ROS users creating snaps, they oftentimes end up using multipl..

Last week I got to see what it was like to be an investigative journalist for a day. It was thrilling. I will get into what I learned but first I waned to give some background on why I was doing this. I have a general curiosity for people. It’s interesting to me to uncover what people are motivated by. Humans are individual snowflakes and no one is exactly like the next. It is our unique experiences that form the way we think and behave, ....

This post is written mostly for fun, not for practical everyday usability (enjoy!). Introduction There was a question on Twitter about alternative options for retrieving the SQL execution plan line ID that Oracle is currently executing. Normally Oracle’s Active Session History shows this info in its PLAN_LINE* columns as I have explained in my asqlmon.sql post. does anyone knows if I can select the equivalent from ASH.SQL_PLAN_L..

So, I’m back . I stopped writing almost four years ago, and a lot has happened since then. Although in the past I did not share many personal details, I want that to change, and I want that to start now. While I used to loosely limit myself to two topics, technology and writing, I plan to broaden my focus considerably in the future. I will save my vision for this site for a later post, but today I will start down this new path with a brief..

Finally some exciting news on the TimeSnapper front. For a long time, the most requested feature for TimeSnapper has been a whole new version, for the Mac OS. Many of our customers and friends have moved from Windows to Mac over the last decade, and consistently told us that they miss the peace of mind and assistance that TimeSnapper provides. One such customer, Jon Schneider was so tired of the situation that he built a new version o....

Back in the early 1990s, teenagers with a drivers license made a hobby of tweaking out their cars - adding custom grills, spoilers, paint jobs, and so on. The more crazy, the better. And since the most common car to perform these modifications on were older Honda Civics, which you could get fairly cheap at the time, especially if they were more than 5 years old and needed a bit of work.

Enforcing logical order of chronologically incoherent commits in Github

Note This issue was fixed and announced on July 14th 2020 The problem Github’s pull request interface has the somewhat unexpected tendency to show your commit history in a different order than what otherwise appears when running git log. Imagine the following master and feature branches. The master branch has 1 commit that adds 1 file named file 0 as shown in the following output: (master)$ git log -..
