      Chris Wellons writes in this article about gap buffers and their performance indications when using multiple-cursors.el. He states that because of the technical implementation of changes in Emacs as gap buffers things like multiple-cursors.el are a performance hit and thus should not be used. Instead one should use search & replace as well as macros.

      I totally disagree. Performance is nothing I should be molested with as a user. When I choose to use a tool I look at the mental overhead it adds. Will it disturb my workflow? How much thought do I have to invest to use it properly? How much thought is necessary to solve my editing problems?

      Macros, for example, add a lot of mental overhead. I have to be aware of many things: I have to ensure that the cursor is at a defined position before executing it (often done with a movement to the beginning of the line), I have to ensure that cursor movements are reproducible in the different contexts, etc, pp. It totally disturbs me in what I am doing right now.

      Search & replace on the other hand add a bit of complexity, but much less than macros. The biggest difference is that I can’t see my changes before executing the replace.

      This is fixed when using multiple cursors: I instantly see my changes and can adopt them, e.g. in case of typos. Also more complex edits are possible since all cursor movements are done on all cursors.

      I just don’t care about the performance. Make it fast enough that I don’t get annoyed by lag, that’s good enough for me.

      Although I’m not a Firefox user these days I have to say I’m impressed by their last release. After years of ignorance followed by years of „we’re not that slow really“ they finally got noticeably faster. It feels much less sluggy and websites which were slow on the older releases now feel much more responsive. Kudos!

      If you would’ve told me that I would have fun in the gym and would do sports five to seven times a week I would’ve laughed at you 😜

      I’m really happy that I can run 10km routes again. I had to stop running a few years ago because of shin splints.

      Since about February(?) I go regularly (three times a week) to the gym and do some strength training and jog about 20 minutes. At the same time I started jogging again, first with small routes (about 4km), then longer routes (8km), first slow then faster. It seems that I avoided shin splints for now despites running three times a week outside and three times a week on the treadmill (only 20 minutes to warm up).

      Recently I read a very interesting (and for me: entertaining) article by Dan Luu titled „everything is broken“:

      If I had to guess, I’d say I probably work around hundreds of bugs in an average week, and thousands in a bad week. It’s not unusual for me to run into a hundred new bugs in a single week.

      This is basically a list of errors and bugs he finds during a week. Go read it - software quality matters!

      Be aware, this is Enterprise grade hardware, it needs a controller to work. The controller can be installed on any computer you own (there is a version for the three major OS), but this controller software has to run when you want to use the wifi.

      Maybe we can now take most of the services off Amazon? Centralizing the Internet sucks…

      The ScanSnap ix500 was for sure a really good invest. I scan every mail I receive and put the original into a file. I put the file onto the attic at the end of the year and done. If I need a document I just send the scanned version.

      Cory Doctorow wites about DRM products and that they are defective by design. He asks a good question: if DRM is so good for us, then why aren’t DRM products labeled as such?

      In our open letter on DRM labelling – a letter signed by a diverse coalition of rights holders, public interest groups, and publishers – we ask the FTC to take action to ensure that people know what they’re getting when they buy products encumbered with DRM.

      He further points out that DRM is often designed as a kill switch:

      What’s more, most modern DRM is designed for “renewability” – which is a DRM-vendor euphemism for a remote kill-switch. These DRM tools phone home periodically for updates, and install these updates without user intervention, and then disable some or all of the features that were there when you bought the product.

      Interesting read!

      Of course things like software quality, bad UX (e.g. still none of the hands-off/continuity features work) are a reason for me: why would I pay the „Apple tax“ if „it simply works“ is no longer true?

      Another reason is the hardware, and that’s a complex one. On one hand Apple hardware is really good, e.g. the touchpads are the best I know. But on the other hand they do stupid things like soldering the SSD and RAM onto the board or gluing the battery. At least the SSD should not be soldered, as I use my hard disks heavily (due to big databases) it is likely that it breaks before the computer is broken.

      Also software freedom is a reason. I like the ideals behind the GNU project and think this is the right way.

      But my absolutely main reason is performance. Linux performs so much better… I have a script touching and inserting about 2 million rows, one at a time. My Linux finishes the job within two hours, while my macbook needs six(!!) hours to complete the task. The overall performance is so much better, and disk I/O is in its own league.

      Nicolas Perriault wrote a nice article about switching away from the Mac to a Linux desktop. He has a similar vita (computer-wise) as me:

      I was a Linux user 10 years ago but moved to being a Mac one, mainly because I was tired of maintaining an often broken system (hello xorg.conf), and Apple had quite an appealing offer at the time: a well-maintained Unix platform matching beautiful hardware, sought-after UX, access to editor apps like Photoshop and MS Office, so best of both worlds.

      I, too, was a Linux user (Gentoo, to be accurate) until some time in 2006 (iirc) and I too got tired repairing my system over and over again. Now he is switching back to Linux:

      To be frank, I was a happy Apple user in the early years, then the shine started to fade; messing up your system after upgrades became more frequent, Apple apps grown more and more bloated and intrusive (hello iTunes), UX started turning Kafkaian at times, too often I was finding myself tweaking and repairing stuff from the terminal…

      My reasons are are a bit different, but I can relate to that.

      For my Emacs using friends: this is an interesting article about a possible Org workflow. The author seems to use Org-mode for about a year and describes the features he can’t live without:

      I’m writing this short guide in an effort to introduce the features in org-mode which I’ve found I can’t live without. I’ll go over how I use org-mode, and it’s powerful built-in summary/calendar view known as org-agenda, in both my work and in my hobby projects. I also include some details about how everything was implemented, or at the very least provide the reader with references to understand my code. This guide is only an introduction to my workflow and is by no means self-contained!

      I read these descriptions with curiosity, I often take a thing or two out of them I didn’t know before. For example last week I learned about the org-agenda-follow-mode, a true piece of heaven!

      In this interesting article Wesley Moore writes about switching away from macOS. He writes about his motivation and reasons:

      • Access to regularly updated, pro hardware.
      • Not restricted to Apple hardware that makes choices that I don’t value, such as:
        • Removing the Esc key.
        • Removing all legacy ports necessitating the use of dongles for everything.
        • Prioritising thinness and weight over everything else.
      • Access to hardware that Apple doesn’t make, such as 2-in-1 laptops.
      • Getting comfortable with an alternative before I’m forced to.
      • The ability to inspect and contribute to the OS I use.
      • Using an OS where developers are first-class citizens.

      I can understand his reasons: I for myself have similar problems with Apple nowadays (besides the moral issues). Interestingly he also favors elementary OS:

      Elementary is stunning and definitely my favourite. It won’t appeal to everyone but their philosophies and direction really resonate with me.

      I’m trying out elementary as well (using it for a week now, I am pretty happy with it), so it was nice to read that somebody else likes it as well - especially since loads of Linux users I know think that this not the way Linux is supposed to be.
