I love markdown , but it lacks the ability to directly create destination anchors (but MarkDownExtra however does for headers )
Anchors can be used to link within and between documents, the foundation of web navigation, and also very important inside documentation.
Luckily, Markdown allows inline HTML , so you can add an HTML destination anchor: an a element with either a name or id attribute.
XHTML deprecated the name attribute , but you should actually use it. The reason is that in HTML5, most browsers create a global JavaScript variable for each id id anchor .
In addition, you should not use a self closing a element: only XHTML supports that .
So the Markdown then becomes something like this:
Learn more about bidirectional Unicode characters
## <a name='possiblePlatforms'>Possible platforms</a>
Link to [possible platforms](#possiblePlatforms).
In the heading, you will see the html for the destination anchor, in the link you will see the MarkDown for the internal source anchor..
The above example will render like this:

An interesting tip at alter table drop column tips for Oracle: unused columns.
I knew about the multi-column syntax for drop column, but the unused columns :
You can also drop a table column by marking it unused and then dropping the column, thusly:
alter table
table_name
set unused column
column_name
;
They will appear in the DBA_UNUSED_COL_TABS view.
After that:
alter table
table_name
drop unused columns
;
You can perform the first statement for a few columns over time, then the last statement will delete them all.
Together with some other views like described in places like oracle – How to check if a column exists before adding it to an existing table in PL/SQL? , you can create nifty scripts for your meta-data maintenance.

A wile ago, I had a this error when trying to get the TIME portion of a DATE column:
ORA-00904: "TIME": invalid identifier
This doesn’t work in Oracle, even though when you search for Oracle convert DATE to TIME you end up at this page listing TIME as a function: 12.7 Date and Time Functions . Alas, that page is for MySQL which is owned by Oracle for a while now .
Back to the query which was like this where date_column was of type DATE .
SELECT
id,
date_column,
TIME (date_column)
FROM some_table
That DATE type actually stores date+time , and since it was filled with Delphi TTime values, the date parts would always be “1899-12-30” (yes, I like ANSI DATE and TIMESTAMP formats ). Oracle doesn’t get that, so I wanted to get the time portion.

This was very useful to get a WebClient with a WebProxy configured to use a proxy server that is based on NTLM authentication.
The note in the MSDN NTLM and Kerberos Authentication . documentation however was totally wrong.
String MyURI = "http://www.contoso.com/";
Note NTLM authentication does not work through a proxy server.
This code works perfectly fine as the CredentialsCache.DefaultCredentials contains your NTLM or Kerberos credentials .

Seems they got only released just yesterday because of the QA effort taking a long time. But it’s good news for Delphi/Rad Studio/C++-Builder Update Subscription members: some fixes are now back-ported to 2 Delphi versions. Which is a new milestone in support from Embarcadero.
Anyway: BLDN .
Note that the list of fixes is at the bottom of these pages:
Source: RAD Studio Hotfixes for XE8 and XE7 with 10 Seattle fixes
I also found out that I never updated the links for XE8 update 1 downloads (I did the original XE8 links Delphi XE8 is out with version 22.0.19027.8951; Spring4D is almost ready. « The Wiert Corner – irregular stream of stuff ) so there they are:

For a short while (from Windows 2003 Service Pack 1 till Windows 2003 service pack 2) some updates used Windows Hotpatching.
Some links on the how/why and how to abuse it:

Thanks Oliver for sumarising this: Translation Memory Tools Tried and Found Wanting – Oli’s Blog
His conclusion support why I see all my clients building their own translation tooling: no 3rd party tool really supports the full process well, especially not the translation memory parts.
