Over 98 percent of the passwords were cracked, thanks to the site’s poor password security.

An interesting discussion on Xeon based 2nd hand systems that are way cheaper than new ones:
[WayBack] People have been asking about the fact I use old Xeon boxes for my development platforms (and indeed more). I want to cover what I use, why I use them, … – Alan Cox – Google+
I still run a couple of HP XW6600 workstations with [WayBack] E5420 processors (of the [WayBack] Harpertown family) to host VMs on. Works splendid.

ESXi 4.0.0.Update01-208167 Whitebox on HP xw6600: success!
Posted by jpluimers on 2017/05/19
Boy, I totally forgot to post this. It runs also ESXi 5.x; I’ve not tried more recent ESXi versions as they just run fine.
As a follow-up on [WayBack] VMware Communities: ESX 3.5 Whitebox on HP xw6600 …, I have installed ESXi 4.0.0.Update01-208167 on a HP XW6600 workstation.
Good news: the generic ESXi 4 installation works, whereas the HP specific ESXi 4 fails (you get a nice purple screen of death).

Wow, this parses in Delphi: `property Foo: string index 0 string read GetFoo;`
Posted by jpluimers on 2017/05/18
Quite a few interesting entries got posted after I published this compiler glitch:
Wow, this parses:
property Foo: string index 0 string read GetFoo;Note the extra “string”.
Found this in an old piece of code so it must have been uncaught by the compiler for quite a while.
Some:
property DepartmentName: string index 0 program library uses unit interface string class read GetCustomDataX;
property Foo: string index 0 unit if library uses unit do not inline file else raise object if is nil read GetFoo;

Anders Hejlsberg on Modern Compiler Construction | Seth Juarez | Channel 9
Posted by jpluimers on 2017/05/18
One of those “must watch” videos if you are remotely or more interested in how compilers influence our day to day coding activities.
The Red Dragon Book, first edition: Compilers. Principles, Techniques and Tools.
It starts out with referring to the Dragon Book (well, actually the first edition of the Red Dragon Book, as there are three) describing the compilers as having front-ends consisting of a Lexer, Parser and Type Checker and back-ends consisting of Code Generator and Emitter. A full compilation is going through all five stages and there is an increasing cost using these traditional stages when going from syntax highlighting via collapsible regions to red squiggles and code completion will need to go further along those stages taking an increasing time – like seconds or even longer – whereas the user experience requires responses in ~ 100 milliseconds where his code might not even compile in the first place.
Then Anders goes on describing Roslyn, TypeScript and Compiler API JSON interfaces to them so you can run them as a service and keep compiler state, rebuilding just enough of the state on source code changes. He goes on talking about how Visual Studio, Visual Studio Code, Command-Line Compiler, Sublime Text and other tools (can) use these APIs to interact with the compiler so it keeps state of slowly evolving code of which the tools than can emit what they need.
Anders explains this much better and much more visually than I do: so it’s a highly recommended video.

Delphi Corner Weblog: New: Velthuis.AutoConsole unit – helps against the “optimised” Embarcadero FastMM fork.
Posted by jpluimers on 2017/05/17
Brilliant:
if it is a console program and it was started any other way (from the Windows Explorer, from the Delphi IDE with or without debugger, from another non-console program), then, before the console window can close, it will display:
