Skoda octavia mk 2 (year 2002) - vacuum pipes layout

I had my car serviced and the car mechanic messed up the vacuum pipes - i had to have them re-fitted in another garage.

The result of the pipe mess up was that the automatic transmission couldn't go into 4th gear.

 I looked on the net but couldn't find easy to follow vacuum pipe layouts, so i drew one after they fixed it:

top view of engine



For non-hebrew users - the middle is the engine (on the engine right side is the vacuum pump). The most right side has the air filter. bottom right is the turbo unit which is behind the engine - you will have to shove your hand all the way behind the engine near the bottom to re-fit that tube if it gets loose.

here more pictures of the layout:

Windows explorer right click "new" item and how it works

      The "New" Menu


There is not necessarily one good way to insert document types to the New menu; it depends on the type of document.

Windows searches for items in the registry at HKCR\.XXX where .XXX is the document extension, such as .bmp for Bitmaps, .xlsx for Excel 2007 Workbooks, .txt for Text Files, etc. For each one of these extensions, there is a ShellNew sub-key.

For documents that do not require predefined parameters, the ShellNew subkey contains a String Value named NullFile with no data. Text Files (.txt) and Bitmaps (.bmp) fall into this catagory.

For document types that do require predefined parameters, there must be a blank document of that type located at the %WINDIR%\ShellNew\ folder. The ShellNew subkey for that type must point to that file. Instead of having a String Value of NullFile with no data, it must contain a String Value of FileName that points to that file by name in the contained data. JPEG Files (.jpeg) and Excel Workbooks (.xlsx) fall into this category.

For example, to create a menu item for an Excel 2007 Workbook, there must be a blank workbook in the %WINDIR%\ShellNew folder (e.g. %WINDIR%\ShellNew\excel2007.xlsx). Then there must be a registry entry that point to this file:
[HKEY_CLASSES_ROOT\.xlsx\ShellNew]
"FileName"="excel2007.xlsx"


In newer office versions you won't find the ShellNew key directly under HKEY_CLASSES_ROOT\.xlsx
instead it is located in HKEY_CLASSES_ROOT\.xlsx\Excel.Sheet.12

The reason is that under HKEY_CLASSES_ROOT\.xlsx there is a key:
(default)=Excel.Sheet.12

which tells windows to search of the ShellNew key under Excel.Sheet.12.

Likewise, the conventional way to disable items from the New menu is to rename the sub-key from ShellNew to ShellNew-, or to simply delete the key (with caution, of course).

(default)=Excel.Sheet.12

and it reappeared in the right click menu "new" items !

faulty wireless charging on nexus 5 problem fix

So my nexus 5 fell on the floor and then suddenly the wireless charging stopped working (or worked only when i pressed hard on the phone when it lay down on the charger.

first here is the fix:
Take your nexus 5 out of it's case (if it has a protective case). Turn it around so you face the back.
Start pressing the cover back on to the phone on the top right area (a little towards the middle of the phone) - until you here a click! - that's it - fixed.

why this worked:
There are small plastic clipses on the inside of the cover that attach the cover to the phone - they run around the rim of the phone and in the middle.

The charging unit is attached to the back plastic of the phone and it has small metal contacts that touch the main board in different sections.

Sometimes when the phone falls, the back separates a little from the phone (the middle plastic internal clipses) and then the back charging unit looses contact with the phone.
