linux – How can I execute a series of commands in a bash subshell as another user using sudo? – Stack Overflow

Posted by jpluimers on 2021/03/31

Based on [WayBack] linux – How can I execute a series of commands in a bash subshell as another user using sudo? – Stack Overflow:

alias restart-spotlight-service-as-root="sudo bash -c 'echo stop;launchctl stop com.apple.metadata.mds;echo start;launchctl start com.apple.metadata.mds;echo started'"

The bold bits above sudo bash -c 'echo stop;launchctl stop com.apple.metadata.mds;echo start;launchctl start com.apple.metadata.mds;echo started' allow the commands between single quotes to executed in one new bash shell under sudo.

msbuild verbosity levels

Posted by jpluimers on 2021/03/31

Passing verbosity levels to msbuild on the one hand can help to quickly locate issues that go otherwise unnoticed, but also make your output so large that it is hard to search through.

Some build targets (Delphi!) do not pass the verbosity to their underlying tools, so for those cases you have to find other means to increase underlying verbosity.

You can always pass msbuild options by using the commandline (even abbreviate them as described in [WayBack] MSBuild Command-Line Reference – Visual Studio | Microsoft Docs: You can specify the following verbosity levels: q[uiet]m[inimal]n[ormal]d[etailed], and diag[nostic]).

Often you also can use your IDE can also specify verbosity levels, for instance:

The currently specified verbosity values in ascending order according to [WayBack] LoggerVerbosity Enum (Microsoft.Build.Framework) | Microsoft Docs:

Quiet 0 Quiet verbosity, which displays a build summary.
Minimal 1 Minimal verbosity, which displays errors, warnings, messages with MessageImportance values of High, and a build summary.
Normal 2 Normal verbosity, which displays errors, warnings, messages with MessageImportance values of High, some status events, and a build summary.
Detailed 3 Detailed verbosity, which displays errors, warnings, messages with MessageImportance values of High or Normal, all status events, and a build summary.
Diagnostic 4 Diagnostic verbosity, which displays all errors, warnings, messages, status events, and a build summary.

Note that in the past, Detailed was called Details:

[WayBack] visual studio 2010 – What is output at the different MSBuild output verbosity levels? – Stack Overflow:

  • Quiet: only shows the result of your build.
  • Minimal: shows some configurations of your msbuild, and the CSC task.
  • Normal: This will show all the targets and its mainly steps.
  • Details: In addition to normal, this flag shows the task and it’s implementation within the each target.
  • Diagnostic: Contains all the information that a MSBuild need and produce, it’s switches, parameteres, prerequisites and etc. The input parameter of the target and task, and also contains the value of the input and output parameter, the detail steps of the task execution. The time execution for each task.

In matrix form, as per [WayBack] Obtaining Build Logs with MSBuild – Visual Studio | Microsoft Docs:

The following table shows how the log verbosity (column values) affects which types of message (row values) are logged.

Quiet Minimal Normal Detailed Diagnostic
Errors
Warnings
High-importance Messages
Normal-importance Messages
Low-importance Messages
Additional MSBuild-engine information

Delphi: got “EOleException with message ‘Microsoft MSXML is not installed'” in a console or test project?

Posted by jpluimers on 2021/03/31

Did you ever get this run-time error in a console or test project?

EOleException with message 'Microsoft MSXML is not installed'

It means that CoInitialize or CoInitializeEx needs to be called in the thread that uses MSXML.

Then an easy workaround is to:

  1. use the unit System.Win.ComObj in any unit that (indirectly) uses Xml.XMLDoc (for instance any unit using an XML Data Binding generated unit),
  2. use the unit System.SysUtils as well (because it defines TProcedure used below)
  3. add this code in in your initialization section (which is what VCL TApplication.Initialize does):

if InitProc <> nil then TProcedure(InitProc); // Calls CoInitialize for the main thread and prevents "EOleException with message 'Microsoft MSXML is not installed'"

The initialization section of System.Win.ComObj sets up InitProc to cals CoInitialize for the main thread, which usually suffices for these simple VCL projects, but not for most console or test projects.

Based on ideas I got after reading [WayBack] 为什么LoadXMLDocument在线程类中使用会报错?-CSDN论坛 (for which Google Translate actually does a goot job [Archive.is])

Warn me whenever and where you are going to use these adapter patterns

Posted by jpluimers on 2021/03/30

Well known in the software development bubble: Adapter pattern – Wikipedia.

If you ever are going to apply the below ones at the hardware level, please warn me in advance when and where you are going to.

~0.5 Ampère over an almost zero sized contact surface is for sure going to result in some burns eventually.

DO NOT EVER DO THIS

Juha is an irresponsible father of two, Nikita reckless, and it’s not just Julien’s tweets that have a life expectancy.
