Visual Studio is a pretty big product and will take over 30GB of disk space after installation

LOL. It’s about half the size of recent Delphi versions.

Anders Live | Build 2016 | Channel 9 – on Turbo Pascal, Delphi, C# and TypeScript
Posted by jpluimers on 2016/04/06
Anders Live – Build 2016 – Channel 9 Stage C907 – Speakers: Anders Hejlsberg, Seth Juarez
Anders explaining about being a pragmatist ever since he started working on the Turbo Pascal predecessor in 1981. It’s been a long way to TypeScript and beyond (:
Lot’s of interesting tidbits about the future of TypeScript and how it relates to other languages.

PS:
The Turbo Pascal predecessors were called Blue Link Software Pascal, Compas Pascal and Poly Pascal as I learned last year while teaching a workshop for DAPUG in Denmark when I bumped into some people working with Anders while he still lived there a long time ago. Later I researched the above links.

A future Delphi won’t download start page content from the Embarcadero site
Posted by jpluimers on 2016/04/05
The “Official statement” of Embarcadero about their recent hacks are in the form of comments on public messages mentioning the hacks, some asking to take discussions offline.
They forgot to comment on Delphi: disable or change your welcome page to not use the Embarcadero site (as that site has been hacked twice this weekend) « The Wiert Corner – irregular stream of stuff, so here is their comment from the G+ thread I posted:
FYI: Future versions will no longer have the banner pulled from the website on the start page.
Source: This weekend, the Embarcadero web site was hacked by AnonCoders. once…
I hope it will be the upcoming Delphi 10.1 Berlin version, but given their speed at responding to security threats, I won’t hold my breath.

PS: what a coincidence that I wrote this yesterday on G+:
I know of a few companies that could benefit from more openness.

RAD Studio 10 next stop: Berlin (via: The inheritance tree of all Fire Monkey objects) but would you really trust it?
Posted by jpluimers on 2016/03/22
Apart from the very interesting poster: the next stop is RAD Studio 10.1 Berlin Version 24.0.22718.6766.
Apparently, I missed the previous RAD Studio 101. Berlin rumour and Tim Anderson mentioning Berlin in New Delphi and C++ Builder Roadmap promises Linux server support « Tim Anderson’s ITWriting as in the Delphi roadmap for 2016 it’s still called BigBen.
The docwiki start page is there, just not open for the public yet: http://docwiki.embarcadero.com/RADStudio/Berlin/en/Main_Page. Like right before Delphi 10 Seattle, it’s only available for writer, l10n, RADBeta, ConnectBeta, Employee.
Similarly, https://sourceforge.net/p/radstudiodemos/code/HEAD/tree/branches/RADStudio_Berlin/ is not there: it was added 20160311.
Still the TLS issues have not been solved, so the very bad SSLLabs rating of F stays stays the same as at before the start the 10 Seattle era.
Also apart from some comments, there still is no central official statement of the recent web-site breaches.
I’m not sure what an eminent new Delphi version can be of use when you can’t be sure your account data is secure and the product download is valid (i.e. not tampered with).
In other words: would you really trust a new Delphi version? I won’t yet, at least not for now.

The Default magic function in Delphi
Posted by jpluimers on 2016/03/17
Stefan Glienke worded it perfectly: Default(typeIdentifier) is a “magic” function that is implemented into the compiler and causes it to generate the correct code – like for records with managed fields it generates a call to FinalizeRecord and some instructions to zero the remaining fields.
Source: I know I can write MyRecordVar := Default(TMyRecordType) because I asked a qu…

Delphi: disable or change your welcome page to not use the Embarcadero site (as that site has been hacked twice this weekend)
Posted by jpluimers on 2016/03/14
Initial hack – image via the forums server.
This weekend, the Embarcadero web site was hacked by AnonCoders. Not once (see also [WayBack] G+ link and [WayBack] DelphiPraxis link and [WayBack] image) but at least twice (see also [WayBack] G+ link and [WayBack] image and [WayBack] Delphi Praxis link and [WayBack] image) where the initial hacked simple text “Hacked By AnonCoders ~ Cyber Caliphate” after having been reverted back to the site – hopefully by Embarcadero staff – was replaced with [WayBack] more graphical content later on.
Hack presenting itself in the IDE – image via the forums server.
The Welcome Page inside the Delphi IDE uses the Embarcadero web site, so the Delphi IDE Welcome Page was also affected (see also [WayBack] this G+ link).
Because the IDE uses this on-line content, potentially any code could be executed inside the IDE (apart from that page being loaded over http, so any man-in-the-middle could abuse this, but I digress). This imposes a security risk as many developers run the IDE from accounts having more rights than the average user.

Delphi: forward declaration of classes and interfaces, but no records.
Posted by jpluimers on 2016/02/24
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

A script to check the frequency of Oracle log switches | Oracle DBA tips
Posted by jpluimers on 2016/02/17
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.
