XAMPP

posted Feb 7, 2019, 2:24 PM by Danny Xu

 Auto installed Apache, PHP, and Perl, MySQL, can use MariaDB already installed.

set up phpMyAdmin to automatically log in as user. I  also created a database user that has full control over (minus grant and lock tables).

XAMPP has a very well designed configuration tool so if we do need to update anything it should be super easy.

Windows 10 in-place reinstall

posted Dec 26, 2018, 11:20 AM by Danny Xu


Running an in-place upgrade worked to fix our instance of Windows 10 that couldn't otherwise be repaired with Command Prompt commands such as

SFC /scannow

and

DISM /Online /Cleanup-Image /RestoreHealth – neither of which would finish their operation on our installation.

SFC works correctly when run from a console in the preinstall environment (PE).  Component store corruption can be repaired from within Windows without an in place re-install.

Mirror a website using wget and VisualWget VWget for Windows

posted Nov 8, 2018, 1:33 PM by Danny Xu


Options to check:

--mirror --convert-links --adjust-extension --page-requisites --no-parent --html-extension
  • --mirror – Makes (among other things) the download recursive.
  • --convert-links – convert all the links (also to stuff like CSS stylesheets) to relative, so it will be suitable for offline viewing.
  • --adjust-extension – Adds suitable extensions to filenames (html or css) depending on their content-type.
  • --page-requisites – Download things like CSS style-sheets and images required to properly display the page offline.
  • --no-parent – When recursing do not ascend to the parent directory. It useful for restricting the download to only a portion of the site.

GPT vs MBR

posted Oct 31, 2018, 9:47 AM by Danny Xu

Windows can only boot from GPT on UEFI-based computers running 64-bit versions of Windows 10, 8, 7, Vista, and corresponding server versions. All versions of Windows 10, 8, 7, and Vista can read GPT drives and use them for data—they just can’t boot from them without UEFI.

libstdc++.so.5

posted Oct 23, 2018, 10:05 AM by Danny Xu

error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

Solution: search for "libstdc" in yast2, most likely libstdc++33-32bit package will provide libstdc++.so.5, if not, try 64-bit
