Worst thing in popularity is not being considered, or found.
Looks like TIOBE is not alone in differentiating Delphi and Pascal, other popularity indexes share the same issue:
More indexes I looked at didn’t show the “runners up”, only the top 5 or top 10, but they may as well have differentiated.
For lang-index, merging Pascal (rank 11) and Delphi (24), would be enough to reach rank 10, ahead of Ruby, just shy of Perl.
For some unfathomable reason, the TIOBE index distinguishes between “Pascal” and “Object Pascal”, and the “Pascal” category is seeing growth:
So it can’t be the old classic procedural Pascal, can it? That leaves only Object Pascal dialects (FreePascal the largest, but also Oxygene and SmartPascal/DWScript). Pascal programming isn’t dead or dying.
In this new episode of the TMonitor saga is a comparison of its locking features vs TRTLCriticalSection, aka the OS-supported critical section mechanism. Is it fair? is it fast?
Fairness means that if you have several threads attempting to lock the same resources, they’ll all get a chance and none of them gets the lion’s share. In other words, that there are no race conditions.
Speed is obvious, it’s about the overhead the locking mechanism incurs.
Edit 2013-08-24: looks like the issue discussed here should be resolved in XE5, cf Monitoring the Monitor by Allen Bauer.
One of the “novelties” of the NextGen Delphi compiler is immutable strings, which I find quite puzzling, for lack of a better word, given that Delphi already had reference-counted copy-on-write strings, and the NextGen compiler uses reference-counted strings.
I always considered that Delphi’s String type was one of its remaining strong points, being a high-level abstraction (higher than Java’s or .Net’s String/StringBuilder dichotomy) with excellent low-level performance (on par with C/C++ character arrays).
From the recent discussions, it appears many don’t know what makes/made Delphi String so special, so here is a quick summary.
This is a practical poll question, what would get you to buy a newer Delphi version?
What would you like to see most and foremost, and would most have a use for?
To force you to choose, you can only pick two items!
For a few weeks now, an experimental JIT compiler has been available in the DWScript SVN for 32bits code. A more detailed article into the hows and whats and WTFs will come later.
Consider this article as an extended teaser, and a sort of call for test cases, benchmarks and eyeballs on the source code.
