[WayBack] Hi there, this is pure curiosity only; but this compiler behaviour seems odd to me. What do you think?… – Agustin Ortu – Google+
The problems start when you prefix the outer class which you have to when using inner consts ([WayBack] Oh nice. Feel free to QP. Fails at least in Delphi XE8. … – Jeroen Wiert Pluimers – Google+).
The big problem in both cases is a formal language specification. The lack of a formal language specification makes it very hard to predict the effect of use cases or generate them for testing.
So this post is yet another request: Please Embarcadero/Idera, come up with a formal language definition for Delphi.

I copied the tables from [WayBack] Memory Performance Information (Windows) as even Microsoft managed to let information “disappear” for EOL products (the en-US version already “disappeared”):
System Memory Performance Information
The following table associates memory object performance counters with the data returned by the memory performance functions in the MEMORYSTATUSEX, PERFORMANCE_INFORMATION, andPROCESS_MEMORY_COUNTERS_EX structures, and with the corresponding information displayed by Task Manager.

I totally missed the passing of Michael Scott Kaplan some 2 years ago, so a belated R.I.P. is in place.
Obituary for Michael Kaplan, Michael Scott Kaplan, 45, passed away Wednesday, October 21, 2015, in Redmond, WA, after a brave battle with MS for 25 years. He was a lead software developer for Microsoft.
Source: [WayBack] Michael Kaplan Obituary – Berkowitz-Kumin-Bookatz | Cleveland Heights OH
Michael was the leading source on i18n, L10N, Unicode, sorting, normalisation and other things having to do with languages, representations and writing.
Besides that he was a really nice guy of which I enjoyed his MSDN materials.
Other people enjoy that too, so I’m glad his writings have been archived: [first archive.is, second archive.is, WayBack] Sorting it All Out: Archives
Here are some additional links:

Sometimes your Atom installation gets so unstable that the quickest solution is a reinstall. For that you need to get a list of user-installed packages, then re-install them.
On Windows your Atom Package Manager apm is here (but not in the path), where the first is version specific and the latter the most recent version:
%LOCALAPPDAT%\atom\app-1.18.0\resources\cli\apm.cmd
%LOCALAPPDATA%\atom\bin\apm.cmd
On Mac OS X, it is here and in the path:
/usr/local/bin/apm
/Applications/Atom.app/Contents/Resources/app/apm/node_modules/.bin/apm
Save your packages:
apm list --installed --bare > package-list.txt
Install packages:
apm install --packages-file package-list.txt
For my own memory, the settings folders:
- Windows:
%USERPROFILE%\.atom
- Mac OS X:
~/.atom

It is a lot (~300 megabyte compressed download!), but worth it.
Here are the links:
And the quote from [WayBack] LAUNCHED https://uberpdf.org/ … – Joe C. Hecht – Google+
LAUNCHED https://uberpdf.org/
…
337 MB of source and utils in 2,308 Files, 910 Folders before you build (not counting 3rd party source UberBuild downloads).
It’s a start, with much to come.It will get easier now that UberBuild is clean.
I will be updating the docs and website in the next few days.
Special thanks …
I already see room for improvement (such as a setup screen for extra compilers such as Delphi and Free Pascal to keep folks out of shell scripts and from hunting for help in the documentation).

This is what DevOps is all about: [WayBack] jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”
I had seen the tweet before, but forgot to save it. Jonas Bandi reminded me of it at [WayBack] Weekend Reader: End of Year Edition – reality-loop.
Jessie is doing great work. For instance, she developed and published contained.af, and nobody captured the flag yet: [WayBack] jessie frazelle on Twitter: «A year ago I made contained.af and it’s launched over 128,000 containers & no one has retrieved the flag».
The game runs in a container, gives you console access and has a bunch of questions. Still need to dig deeper in it, as it is a fascinating set-up. If you like to try it:
Wishing you a year where nobody captures your flags (:

A nice discussion followed on [WayBack] Senior Oops Engineer on Twitter: “what’s a blockchain?” It’s like git but for destroying the environment.
It basically comes down to: can alternatives like git together with a set of rules and contracts to facilitate upstream pushing to a global order of changes be sufficient alternative to the very resource intensive “calculate proof of work to achieve consensus”.

Bugs happen: [WayBack] Did I miss something ? I’ve tried to add a custom image loader for FMX … TBitmapCodecManager.LoadFromFile calls TImageTypeChecker.GetType that returns ONLY predefined image types ! (gif, bmp, png, tiff, jpg) … – Paul TOTH – Google+
I’m not so much surprised by bugs, but what scares the heck out of me is that since about halfway October 2017, there are 900+ Reported issues with status Unresolved (i.e. no change to the issue after it got reported).
Before switching to half-year product release cycles, the yearly ones had an issue triage cut-off date of about 3-6 months.
Now back on yearly cycles, I don’t expect that to be much different.
Expecting a new release in the halfway March 2018 till beginning May 2018 time frame, and assuming the past being a good indication of the future, the window of processing issues is closing soon.
I really hope I am wrong and wish 2018 turns out to he a great Delphi year.

Sorry this post became victim to the “Missed Schedule” issue (I finally found out there is a ridiculous limit of 100 scheduled posts over which scheduling becomes unreliable; this limit used to be much much larger in the past).
