One of the best to graphs diagrams of LINQ I know is in Mastering C# – Lecture Notes Part 2 of 4 – CodeProject [WayBack]
The LINQ explanation in that article [WayBack] is top notch as well. Thanks Florian Rappl [WayBack]!

Closed: HDD Guardian – Home
Posted by jpluimers on 2017/08/16
Too bad: it was fun while it lasted.
Mid april 2017 [WayBack] HDD Guardian – Home closed down, so the latest commit removed all the [WayBack] HDD Guardian – Source Code.
HDD Guardian provides a Windows front-end for smartctl, a utility which monitors your hard drive(s) and SSD(s) for health status, taking advantage of S.M.AR.T.
The WayBack machine and Archive.is have archived some links though:
- 2017: [Archive.is] [WayBack] HDD Guardian – Home – most recent home page
- 2017: WayBack: HDD Guardian – Documentation – Documentation – Supported/unsupported controllers
- 2016: WayBack: HDD Guardian – Documentation – News
- 2016: WayBack: HDD Guardian – Documentation – FAQ / Known Issues
- 2017: [Archive.is] HDD Guardian – Source Code – Changesets
- 2017: HDD Guardian – Download: HDD Guardian 0.7.1 (though the downloads themselves are not available).
Anyone interested in getting it before codeplex itself shuts down:
git svn clone https://hddguardian.svn.codeplex.com/svn
Edit 20210909:
Note that a while ago, the salvaged source code got pushed to GitHub: [Wayback/Archive.is] native-api/hddguardian: A GUI app to watch and manage HDDs’ S.M.A.R.T., based on smartmontools. Salvaged from https://hddguardian.codeplex.com

What is the right way to convert into UNIX timestamp from the date and time in C/C++? – Stack Overflow
Posted by jpluimers on 2017/08/16
Thanks R.. for answering this:
POSIX has a formula for exactly what you want:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_15 [WayBack]
tm_sec + tm_min*60 + tm_hour*3600 + tm_yday*86400 + (tm_year-70)*31536000 + ((tm_year-69)/4)*86400 - ((tm_year-1)/100)*86400 + ((tm_year+299)/400)*86400This works whenever you have a broken-down time in GMT, even if the underlying system’s
mktime, etc. functions do not use the same formattime_tas “Unix timestamps”.If your original time is in local time, you can use
mktimeandgmtimeto convert it to GMT using the system’s notion of timezone rules. If you want to apply your own timezone offset rules, just do that manually before using the above formula.
Source: What is the right way to convert into UNIX timestamp from the date and time in C/C++? – Stack Overflow [WayBack]
For testing and more examples: Epoch Converter – Unix Timestamp Converter [WayBack]
Hopefully this will help me getting better implementations for these:
- Monolithic function that requires splitting up: Useful Universal Date Converter function – MikroTik RouterOS [WayBack]
- Calculate Day of Week from Date – MikroTik RouterOS [WayBack]

Why doesn’t RevertToSelf undo the most recent SetThreadToken? | The Old New Thing
Posted by jpluimers on 2017/08/16
Oops: I fell in this trap as well: When you call SetThreadToken, [WayBack] it replaces the token. When you call RevertToSelf [WayBack], the token is cleared and the thread no longer has a token. Maybe RevertToSelf should have been named ClearThreadToken, since that would emphasize that the function erases any existing thread token, leaving the thread to inherit the identity of its host process.

Some links on Belise/Elise licensing server (yes, AppWave is dead or at least: should be)
Posted by jpluimers on 2017/08/15
Some links on the Embarcadero License Center server (formerly known as Belise and Elise) from my contributions to these G+ threads:
- Anyone here ever start out using Workstation licenses then switch to eitherNetworked Named User or Networked Concurrent ?… [WayBack]
- Does anyone know what is happening with AppWave? Is it still going, or has something replaced it? – Nicholas Ring – Google+ [WayBack]
When for instance your workstations cannot communicate to the external license servers or you want to run concurrent Delphi/C++-Builder/RAD-Studio instances on your local network, you need to run the Elise licensing server on your network, which requires you to have a server with Java running somewhere.
Despite some of the documentation, it runs on more recent Windows versions too.
Not sure about the money: it’s just that a few clients of mine use it as it makes it easier to manage licenses when you switch contractors or not having various team members only use Delphi part of the time.

Inline code highlighting in reStructuredText – Stack Overflow
Posted by jpluimers on 2017/08/15
To inline code inside reStructuredText embed it with back-ticks and pre-pend the first back-tick with :code:
This is how some text with :code:`a = b + c` embedded will look like.
This is how some text with
a = b + cembedded will look like.
Source: Inline code highlighting in reStructuredText – Stack Overflow [WayBack]
The above is in addition to the a = b + c that renders to default code as described for instance by reST – reStructuredText — Sphinx/Rest Memo v1.0-14-ga2798e1 documentation [WayBack]

Experiments in Uniform Memory Management – grijjy blog
Posted by jpluimers on 2017/08/10
TL;DR of [WayBack] Experiments in Uniform Memory Management – grijjy blog:
the closest we can get to uniform memory management is to use object interfaces
The reason is that cross platform memory management in Delphi is a mess.
Via: [WayBack] Erik van Bilsen – Google+ I share some results of my quest for a uniform memory management model across all platforms. For some reason, it also touches on old-school linked lists and new-school messaging…

Delphi Error: E1026 File not found: ‘Controls.res’ – Google Search
Posted by jpluimers on 2017/08/10
As since E1026 is [WayBack] documented as x1026 since Delphi 2007 probably because it can manifest itself as W1026 as well, I thought Delphi Error: E1026 File not found: 'Controls.res' also be related to F1026: When the Delphi XE5 commandline compiler fails with error F1026: File not found: ‘False.dpr’
But it wasn’t.
Then I thought it might have to do with Unit Scope names.
Often an upgrade of a pre-XE2 project where old names of units (like Controls [no WayBack]) were used in stead of Unit Scoped [WayBack] prefixed units (like Vcl.Controls [WayBack]) wrongly makes the Unit Scope Names list in Project > Options > Delphi Compiler empty.
Such an empty list causes the normal mapping of unit name to scoped unit name as described in Unit Names Alphabetical List with Unit Scopes [WayBack] to fail. That results in a F2613 Unit ‘%s’ not found [WayBack] or rarely a F1027 Unit not found ‘%s’ or binary equivalents (%s) (Delphi) [WayBack].
So that wasn’t the cause either.

Using BC4 OSX with Version Control Systems
Posted by jpluimers on 2017/08/10
A great thread about Using BC4 OSX with Version Control Systems, -Tools and IDEs.
Some highlights:
- git
- Cornerstone
- Mercurial/Hg
- SourceTree
- Syncovery
- IntelliJ IDEA
- Tower
- Perforce
- Subversion/SVN
- Eclipse and Team Explorer Everywhere (TFS)
- SmartCVS
- Android Studio
- Using BComp instead of Beyond Compare.app for VCS and OSX Command Line Utilities
