TMemIniFile have non-virtual SetStrings procedure.
One of the classic Delphi RTL examples of Delphi team members not reading Delphi Component Design by +Danny Thorpe
You can still get it for a few dollars, used: http://www.amazon.com/Delphi-Component-Design-Danny-Thorpe/dp/0201461366

Delphi XE8 [dcc32 Fatal Error] dcc32_F2084_C2359.dpr(30): F2084 Internal Error: C2359
Posted by jpluimers on 2016/10/05
Fails in Delphi XE8 with a nice [dcc32 Fatal Error] dcc32_F2084_C2359.dpr(27): F2084 Internal Error: C2359
It is fixed in Delphi 10.0 Berlin, but of course a C2359 search does not reveal that as Quality Portal is behind a wall. So for future reference the bug: [RSP-13471] Int64 for loops can generate Internal Compiler Error – Embarcadero Technologies. Thanks +Stefan Glienke for mentioning the issue.
program dcc32_F2084_C2359;
type
TNumber = Int64; // UInt64; // fails too; other numeric types do not fail. Fails in a unit as well.
TNumbers = TArray;
TNumberRange = record
strict private
function GetLowerBound: TNumber;
public
function Numbers: TNumbers;
property LowerBound: TNumber read GetLowerBound;
end;
{ TNumberRange }
function TNumberRange.GetLowerBound: TNumber;
begin
Result := Default(TNumber);
end;
function TNumberRange.Numbers: TNumbers;
var
lValue: TNumber;
begin
for lValue := LowerBound to LowerBound do
;
end;
begin
end.

If you thought you could do multi-threading, then play “The Deadlock Empire” games
Posted by jpluimers on 2016/10/04
Source: The Deadlock Empire
Via: Face the dragon. Learn the ropes of concurrent programming. – Lars Fosdal – Google+
Source code is available and focuses on C#; maybe one day I’ll make a Delphi version: deadlockempire/deadlockempire.github.io: The Deadlock Empire: Slay dragons, learn concurrency!
BTW: a great book (with nice illustrations at both github and kernel.org) is Source: Is Parallel Programming Hard, And, If So, What Can You Do About It? [WayBack]

Encoding is hard… so how did the single quote become a circumflexed a followed by Euro sign and trade mark?
Posted by jpluimers on 2016/10/04
A while ago (in fact more than a year), I posted Encoding is hard… go G+ with the below picture.
[Wayback] ftfy (“fixes text for you”, a parody on “fixed that for you”) [Wayback] fixes it, but:
How did the single quote become “’“?
Actually, because of a a common “beautification” of many Office suites (Microsoft and Open alike), the single quote was a special one: a Unicode Character ‘RIGHT SINGLE QUOTATION MARK’ (U+2019) which in UTF-8 is encoded as 0xE2 0x80 0x99.

Fun deciphering thermometers
Posted by jpluimers on 2016/10/03
From a while ago: a Norwegian (left) and German (right) thermometer. In dialect. Because.
Anyone having more of these in other dialects?
Sources:
- Only a few of the temperature references on the right side are possible to translate, as the rest use terms from the local dialect, unknown to those not born here – Lars Fosdal – Google+
- Here’s the thermometer I’ve been talking about. – Lübbe Onken – Google+

Viewing an USB camera on Mac OS X without mirroring
Posted by jpluimers on 2016/10/03
Even though Photo Booth has an “Auto Flip New Items” option, but that only works for stills, not videos.
I needed it to see without mirroring the images from a DBPOWER 2 Million Pixels Cmos 7M/23FT USB Waterproof HD 6-led Borescope Endoscope Inspection Tube Visual Camera.
What does work are these:
- QuickTime Player – built in app which can also do movie recording. You start recording a new movie without actually pressing the record button.
- QCamera – free tool from the App Store by Simon Guest.
I forget how I bumped into QCamera, but later I found out he posted on apple.stackexchange.com.

Dan Hirsch: You probably have a Google Apps Account. There’s no switch back to old G+ for Google Apps aka GSuite users anymore.

SSD BareMetal cloud servers, Simple and flexible pricing, enjoy a predictable cloud pricing model | Scaleway
Posted by jpluimers on 2016/09/30
So I won’t forget:
SSD BareMetal cloud servers, Simple and flexible pricing, enjoy a predictable cloud pricing model
Source: Pricing BareMetal | Scaleway
They are based in France and host both ARM and x86 servers at very competitive prices.
At the time of writing the cheapest bare metal x86 server has 8 GB or RAM, 4 cores and 50 gigabyte SSD storage at EUR 12/month. VPS are even more affordable. 50 gigabyte extra is EUR 1/month.

InitialKeyboardIndicators registry setting to fix NumLock in a certain state.
Posted by jpluimers on 2016/09/30
There are odd things with the InitialKeyboardIndicators registry setting. Technet only documents bitflag value 2.
According to the docs it should be a bitflag, but sometimes you encounter InitialKeyboardIndicators value 2147483648 (0x80000000) especially as part of the .DEFAULT profile at HKEY_USERS\.DEFAULT\Control Panel\Keyboard.
The problem I had was having these symptoms:
- while logging in locally, I manually turned of the NumLock (as I have a 46W6740 UltraNav keyboard without a numeric keypad)
- after logging in locally, it magically turned itself on even with
InitialKeyboardIndicators=0in my local profile atHKEY_CURRENT_USER\Control Panel\Keyboard. - after logging in locally and turning it off, future local logons would keep it off
- after logging in remotely, it would magically turn itself on while logged in
- after having logged in remotely, the local logon console would have it turned on again
After reading Num Lock problem: Strange number in InitialKeyboardIndicators in Registry, I set both values to 0.
Now that it is 0 in both at HKEY_USERS\.DEFAULT\Control Panel\Keyboard and HKEY_CURRENT_USER\Control Panel\Keyboard, symptoms 4-5 still hold. Strange.
It is not the same problem as Num Lock state not retained after resume from Hybrid Shutdown in Windows 8 and Windows Server 2012.
If it persist, I might just put a script in: [Partially Solved: re-wired keyboard lol] Registry key “InitialKeyboardIndicators” NEVER keeps NumLock ON + ScrollLock ON (6) at startup and reverts back to NumLock ON (2).
