While uploading an image I got:

Building a C++ project with MinGW using Visual Studio Code

In CMake Tools extension settings I specified my CMake path:

and built my project with MSVC 2022 first and then switched to MinGW.

Building a project with MSVC 2022

On my machine with installed MSVC 2022 it automatically generated configuration file %LocalAppData%/CMakeTools/cmake-tools-kits.json:

    "name": "Visual Studio Professional 2022 Release - amd64",
    "visualStudio": "04bbaecf",
    "visualStudioArchitecture": "x64",
    "preferredGenerator": {
      "name": "Visual Studio 17 2022",
      "platform": "x64",

Compiling a C++ source file in Visual Studio Code with MinGW

I followed this instruction and configured C/C++ extension as follows:

            "cppStandard": "c++17",
            "intelliSenseMode": "windows-gcc-x64"

Building QT6.4.2 for MacOS and iOS

Build QT for MacOS separately in Debug and Release configuration:

tar xf qt-everywhere-src-6.4.2.tar.xz
cd ~/build/qt

export MY_MODE=release
#export MY_MODE=debug

Touch target size on Android

Probably QT “Fusion” is not an appropriate style for Android apps, because its buttons height is not enough:


“One Edit Apart” task on Yandex interview

The task is to write one_edit_apart function that determines is it possible to make two given strings equal by replacing, adding or removing one symbol. The equal strings are considered to be equal, for example:

one_edit_apart("cat", "at") == true
one_edit_apart("cat", "cats") == true
one_edit_apart("cat", "cast") == true
one_edit_apart("cast", "cats") == false
one_edit_apart("cat", "cut") == true
one_edit_apart("cat", "dog") == false

The task is trivial, but Yandex interviewers require all the calculation to be done exactly in their inline editor without debugging and compiling and they do not accept the solution until it works for all possible input. The obvious solution is to truncate equal heads and equal tails and check if the lengths of remaining strings are not greater than 1, but if you forgot to handle the case when heads and tails intersect (with “a” and “aa”, for example) they will say “ooops…., you did a newbie mistake that 1-st year students usually do” and if this all takes more than 40 minutes you fail to pass the test. Below I provided the source code they are most likely to accept:


QT has Translation Rules for Plurals

For example, there is the following content in qt-everywhere-src-6.4.1\qttranslations\translations\linguist_ru.ts:

<message numerus="yes">
    <source>Dropped %n message(s) which had no ID.</source>
        <numerusform>Удалено %n сообщение, у которого не было ID.</numerusform>
        <numerusform>Удалено %n сообщения, у которых не было ID.</numerusform>
        <numerusform>Удалено %n сообщений, у которых не было ID.</numerusform>
