Just while I was watching a nice DEFCON video about security
I came across these two links:
It really looks like too many companies are not genuinely interested in your security.

As Delphi allows to forward declare both classes and interfaces, people often wonder about records.
The short answer: you can’t forward declare record types.
The long answer: you can’t directly, but you can indirectly either reference based (through pointers or callbacks with const parameters) or operator based (through operator overloading).
I think the reason forward declaration of classes and interfaces is possible because they both are reference types, so referring does not impose copying.
Anyway, the trick is this:
You can’t have forward declarations for record types. Define both Implicit operators in the second type

This indeed works very well:
All console output is shown in the build log.
So when you need more context on tests that succeed, you can just output them on the Console.
A practical use: testing the sending of SMS messages over HTTPS where the intermediate proxy can change and was giving different effects.
Logging the actual proxy used correlated some run-time findings. Based on that we could write better tests.

If for instance your Boxee gets old or breaks down, you can use a Raspberry Pi as a replacement with Kodi as media player.
This combination will understand the Video+USB over HDMI which most TV supports officially named HDMI-CEC , but most vendors “invented” their own names (see list below).
The core is the kodi support for CEC.
Basically it comes down to using three cables going to the Pi: Power from TV (or some other source), HDMI to TV, and wired Ethernet. And a distribution for RaspberryPi containing kodi will work, for instance from OpenELEC Mediacenter – Download: Raspberry Pi Builds
Chad MILLER has more details on how to get this to work: My Boxee box is getting old, but I knew of no replacements. The problem is I …
Names known for HDMI-CEC via Wikipedia:
Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link and Regza Link (Toshiba), RIHD (Remote Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
Because of the naming, turning on CEC can be confusing: How to Enable HDMI-CEC on Your TV, and Why You Should

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:
| ## <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:
Link to possible platforms.

Just updated Cool: Vysor screen sharing by Koush with this:
Escape -> Back Button;F1 -> Menu Button;Home -> Home Button;Middle Click -> Home;Right Click -> Back
Now hopefully the screen resolution thing will be fixed: [Wayback/Archive] github.com/koush/vysor.io/issues/68

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:
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.
