If Beyond Compare indicates “editing disabled” after starting from SourceTree, then your integration is wrong.

Posted by jpluimers on 2017/10/16

SourceTree 2.1 still doesn't recognise that Beyond Compare is installed.

SourceTree 2.1 still doesn’t recognise that Beyond Compare is installed.

I noticed that on my Mac, Beyond Compare wasn’t able to edit diffed files when it had been started from SourceTree. This struck me as odd since on Windows this worked fine. So I did a bit of digging and found out both SourceTee and I screwed up:

Editing Disabled

Luckily [WayBack] Zoë Peterson (lead developer on Beyond Compare and formerly Turbo Power Abbrevia project admin) had answered this before, and all these show “Editing disabled” in the user-interface:

Beyond Compare will disable editing of a file any of the following reasons:

  • It’s one of the input files in a 3-way merge
  • The comparison was cancelled
  • The comparison encountered an error (corrupt file, invalid character encoding, out of memory, gamma rays, etc)
  • The file format’s conversion settings don’t support converting back to the original format (MS Word, PDF)
  • The file is on a read-only “filesystem” (7zip/RAR/CHM archives, CD/DVD-ROMs)
  • A file or parent folder had editing explicitly disabled by the user in the session settings or using the /ro command line switches
  • The viewer itself doesn’t support editing (eg, Hex Compare)

Source: [WayBack] version control – Beyond Compare 3 editing disabled – Stack Overflow

So the last instruction should be:

Set both Visual Diff Tool and Merge Tool to Other, then set both the Diff Command and Merge Command to the value you obtained above (in my case /usr/local/bin/bcomp) and these arguments:

  1. Diff Command Arguments
    "$LOCAL" "$REMOTE"
  2. Merge Command Arguments
    "$LOCAL" "$REMOTE" "$BASE" "$MERGED"

Note that somewhere during 2.2, SourceTree has added Beyond Compare integration and fixed some of the issues, but there are still issues left:

No Editing Disabled

There is only one occasion where the UI does not show “Editing Disabled”, but where you cannot edit the file itself (you can only edit the current line in the line diff view at the bottom of the UI). Zoë mentioned that too:

…

Also, the Full Edit (F2) toggle in the Text Compare View menu switches between inline editing and line-based mode. If it’s disabled you can copy/delete whole lines and type in the line details edits at the bottom of the window, but the main windows won’t have a cursor, typing is disabled, and it will always select whole lines. Unlike the above items, this doesn’t show “Editing Disabled” in the status bar.

By default this setting is bound to the F2 key on Windows, so if you accidentally press that when Beyond Compare is active, you might be in for a surprise.

When you believe that you have a keylogger or some sort trojan | Official Apple Support Communities

We thought one of our Macs was compromised, but it wasn’t: it had too many web browsers open so it was crawling like a snake.

The below terminal commands and EtreCheck [Source: etresoft/EtreCheck: Source code for EtreCheck] helped to find out what was running:

Mac OS X – Hardware Monitor Help: remove com.bresink.driver.BRESINKx86Monitoring

Posted by jpluimers on 2017/10/13

Just in case you have this driver installed:

$ kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
com.bresink.driver.BRESINKx86Monitoring (9.0)

[WayBack] Hardware Monitor Help shows how to remove it:

  1. Ensure you are logged in as user with administrative rights.
  2. Use the Finder to open the folder Library at the topmost level of your system volume, and inside it, the folder StartupItems. If the driver is still installed, you will see the folder BRESINKx86Monitoring at this location.
  3. Drag the folder BRESINKx86Monitoring to the Trash. OS X may ask for your administrator password.

The cloud has no walls: cache-based jamming agreement to communicate over the CPU cache even without rights

ThreadBarrier/ThreadBarrier.pas at master · lordcrc/ThreadBarrier

Posted by jpluimers on 2017/10/12

I mentioned Asbjørn Heid on wiert.me before. While prepping for the Deadlock Empire workshop at EKON20, I needed a Delphi equivalent for the .NET [Way: Barrier Class (System.Threading)

The game uses that in level deadlockempire.github.io/#H4-Barrier [WayBack].

HTML indentation: 2 spaces

Posted by jpluimers on 2017/10/12

Using too many editors in too many environments, tabbed files usually kills my productivity.

Not just because the structure of the indented code, also because most editors are stupid enough to also use tabs beyond the indentation, for instance for carefully aligned initialisation statements.

Changing the tab-size effectively waves good bye to those.

It’s weird (Wiert loves that word) that HTML peeps even argue about tabs versus spaces:

Most people still use HTML for pixel perfect rendering and spaces help getting character perfect rendering of the source code.

I was glad to bump into [WayBack] Jefferson Lima answering this on Stack Overflow:

The Google HTML/CSS Style Guide and the W3School HTML(5) Style Guide recommend 2 spaces.

This article also brings an analysis of the effect of tabs vs spaces in the resulting file size.

Source: [WayBack] html5 – html indenting standard, tab or two spaces? – Stack Overflow

So: use 2 spacec for HTML indent.

It doesn’t really matter in transmitted size (minified compressed transfer difference is ~0% and the usual image bloat is way larger than the HTML anyway – just try www.webbloatscore.com and watch).

References:

  • Indent by 2 spaces at a time.
  • Don’t use tabs or mix tabs and spaces for indentation.

Source: [WayBack] Google HTML/CSS Style Guide

  • Do not add blank lines without a reason.
  • For readability, add blank lines to separate large or logical code blocks.
  • For readability, add two spaces of indentation. Do not use the tab key.
  • Do not use unnecessary blank lines and indentation. It is not necessary to indent every element.

Source: [WayBack] HTML5 Style Guide

Tabs Spaces Saving
Raw file size 1403 bytes 1703 bytes 300 bytes/18%
Raw file GZipped   327 bytes   332 bytes      5 bytes/1.5%
Raw file minified 1199 bytes 1199 bytes      0 bytes/0%
Minified & GZipped   312 bytes   312 bytes      0 bytes/0%

When minified, it doesn’t matter if tabs or spaces are used, since they are all stripped away.
