To reset Ubuntu Unity or any other Linux desktop with GNOME/MATE DEs to its default settings, run:
dconf reset -f /
Source: [WayBack] Reset Linux Desktop To Default Settings With A Single Command – OSTechNix
I need to check if it works on OpenSuSE with XFCE as there the dconf command is installed, but I still have a default desktop (mainly because most of the work I do is using a terminal over ssh).

One more thing to take away from Procedural Programming: It’s Back? It Never Went Away – Kevlin Henney [ACCU 2018] – YouTube was explained in [WayBack] How to Design Early Returns in C++ (Based on Procedural Programming) – Fluent C++.
Though in C++, it applies to all programming languages that stem from a procedural background (Pascal, C#, Java, golang, to name just a few).
The article is about keeping an if/else-if/else tree, even when they can be removed becomes some of their bodies perform an early return, as
In C++, as well as in other languages, the
returnkeyword has two responsibilities:
- interrupting control flow,
- yielding a value.
It basically comes down to this argument:
Essentially, the argument for Code #1 is that you need to know less to understand the structure of the code.
Indeed, if we fold away the contents of the if statements, Code #1 becomes this:
The structure of the code is very clear. There are 4 different paths based on the
year, they’re independent from each other, and each path will determine the boolean result of the function (if it doesn’t throw an exception).Now let’s see how Code #2 looks like when we fold away the if statements:
And now we know much less. Do the if statements contain a
return? Maybe.Do they depend on each other? Potentially.
Do some of them rely on the last
return falseof the function? Can’t tell.With Code #2, you need to look inside of the if statement to understand the structure of the function. For that reason, Code #1 requires a reader to know less to understand the structure. It gives away information more easily than Code #2.

Steps:
Tools followed by Any Time, then Custom range often does not show a dialog.&tbs=qdr:y to the URL magically enables that popup:This is how I found the post in Did you hear about the man who got cooled to absolute zero? He’s 0K now.
I think cdr stands for custom date range and qdr for a built in date range as after searching for the abbreviations, I found [WayBack] Google Search URL Request Parameters | DETECTED that discusses tbm and tbo in addition to tbs.
The trick above is the successor of [WayBack] Filter Google Results by Date with a URL Trick which appended &as_qdr=d.

[Archive.is] Need to try this: … multiple default index properties having the same name …getters can be overloads … resolve …by type signature … – Thomas Mueller (dummzeuch) – Google+, thanks to marck for this brilliantly simple example:
private function GetColumnValue(const ColumnName: string): string; overload; function GetColumnValue(Index: Integer): string; overload; procedure SetColumnValue(Index: Integer; const Value: string); public property Values[const ColumnName: string]: string read GetColumnValue; default; property Values[ColumnIndex: Integer]: string read GetColumnValue write SetColumnValue; default; end;This means:
- you can have multiple default indexor properties
- the multiple indexor properties can have the same name e.g., Values
- the properties getters can be overloads (i.e. have the same name) e.g., GetColumnValue
- Delphi will resolve the overloads by type signature

Some systems to not have a %windir%\ShellNew directory, so here are some links and observations on ShellNew entries in the registry.
Originally, I needed this for Creating a blank Visual Studio solution without a directory, and sln Format Version numbers but found a default installation did not have a %windir%\ShellNew directory.
A similar Windows 8.1 system had these files there:
EXCEL12.XLSXMSPUB.PUBOn the Windows 10 system, these files were in C:\Program Files (x86)\Microsoft Office\root\vfs\Windows\SHELLNEW, so apparently, Windows 10 has moved more into a Virtual File System structure.
The key HKEY_CLASSES_ROOT\.zip\CompressedFolder\ShellNew on both systems has the below values, indicating you do not need a file template: a binary template in the registry suffices:
Data having REG_BINARY content of a 22-byte empty .zip fileItemName having a REG_EXPAND_SZ content pointing to @%SystemRoot%\system32\zipfldr.dll,-10194The key HKEY_CLASSES_ROOT\.rtf\ShellNew on both systems has the below values, indicating you do not need a file template: a text template in the registry suffices:
Data having REG_SZ content of a 7 character file content {\rtf1}ItemName having a REG_EXPAND_SZ content pointing to @%ProgramFiles%\Windows NT\Accessories\WORDPAD.EXE,-213The key HKEY_CLASSES_ROOT\.bmp\ShellNew on both systems has the below values, indicating you do not need a file template: a zero byte template in the registry suffices:
NullFile having an empty REG_SZItemName having a REG_EXPAND_SZ content pointing to @%systemroot%\system32\mspaint.exe,-59414At HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders, is a value named Templates having an absolute path which can be expanded from %AppData%\Microsoft\Windows\Templates.
That directory was empty, but it is connected to the HKEY_CURRENT_USER\Software\Classes counterpart of HKEY_CLASSES_ROOT (the latter is an alias for HKEY_LOCAL_MACHINE\SOFTWARE\Classes).
So in stead of putting template files in %WinDir%\ShellNew plus registering them underHKEY_CLASSES_ROOT, you can put them in %AppData%\Microsoft\Windows\Templates and register them under HKEY_CURRENT_USER\Software\Classes.
Since people have requested empty solution files to be created without creating a directory for a long time ([WayBack] create solution without folder – Visual Studio) and Visual Studio still does not allow you to do that, I have amended the %WinDir%\ShellNew based solution I created some 7 years ago at Creating a blank Visual Studio solution without a directory, and sln Format Version numbers, to a current user based one:
[WayBack] jeroenp / wiert.me / commit / 01e4430712a6 — Bitbucket:
Amend empty Visual Studio templates to support%AppData%\Microsoft\Windows\Templates referenced from HKEY_CURRENT_USER\Software\Classes
I might be able to morph this into a registry-only solution by using REG_MULTI_SZtyped values containing the actual .sln template content as multi-line strings separated by zero bytes. Some starting links on this for future reading:
HKEY_CLASSES_ROOT.This is a special registry hive that combines the local user’s associations in HKEY_CURRENT_USER\Software\Classes with the system’s associations in HKEY_LOCAL_MACHINE\Software\Classes.–jeroen

Cool research paper from a while back but still soo relevant:
The project page for an ICSE’17 paper, To Type or Not to Type: Quantifying Detectable Bugs for JavaScript
JavaScript is also a dynamically typed language for which static type systems, notably Facebook’s Flow and Microsoft’s TypeScript, have been written. What benefits do these static type systems provide?

[WayBack] Where is the Chrome settings file? – Super User, on various platforms as a folder named Default under:
In Windows:
%LocalAppData%\Google\Chrome\User Data\
In OS X:~/Library/Application Support/Google/Chrome/
In Linux:~/.config/google-chrome/
The easiest way to find out the actual location is by browsing to chrome://version/ as per [WayBack] google chrome – Disabling “Sign In ” tab on startup – Super User. There the entry Profile Path will show the actual profile location.
Inside that path is a JSON file called preferences which you can edit if Chrome is closed (since Chrome will overwrite it regularly when active).
A few entries I saw are interesting:
"session": {
"restore_on_startup": 1
},
"exit_type": "Crashed",
"exited_cleanly": true,
"exit_type": "Normal",
"exited_cleanly": true,
A trick to restore the session after you quite Chrome is to replace "exited_cleanly":true with "exited_cleanly":false in the Preferences file.
