Via [WayBack] What are the size restrictions for the VCL controls like TPanel and TPaintBox.? Are they documented anywhere? I’m talking about placing these on a TScro… – Thomas Mueller (dummzeuch) – Google+:
Some Windows messages use the LPARAM to carry width and height, which allows only 16 bit for each.
So 32k-1 (or decimal 32767) is the maximum size of a GDI based visual element in Windows.

Cool tool, but be aware it does aJavaScript:xmlhttpPost from , so your data can be logged [WayBack] Redirect Detective – A Free Tool To Trace Where Redirects End Up.
For http://www.xs4all.nl/~jp, it shows these redirects (where in bold I’ve listed the changes):
Oh and it runs this call: JavaScript:xmlhttpPost("/linkdetect.px")?word=www.xs4all.nl%2F%7Ejp from [WayBack] redirectdetective.com/ajax.js.
Note that this shows more redirects than the plain http ones, so wget from [WayBack] wget – How do I display all URLs in a redirect chain? – Unix & Linux Stack Exchange shows this:
$ wget http://www.xs4all.nl/~jp 2>&1 | grep Location:
Location: https://www.xs4all.nl/~jp [following]
Location: https://jp.home.xs4all.nl/ [following]

Me at [WayBack] emulation – How to safely remove/uninstall Android Virtual Device .img files added by Visual Studio Emulator for Android – Stack Overflow:
Since after uninstalling the “Visual Studio Emulator for Android” component, you cannot get to the “AVD Manager” any more, you have to manually delete this directory:
%LocalAppData%\Microsoft\VisualStudioEmulatorThis works for both Visual Studio 2017 and Visual Studio 2015.
In addition, you might want to run “AppWiz.cpl“, then remove “Android SDK Tools”, which is also not automatically removed by the Visual Studio installer (at least not in Visual Studio 2015).
This will get rid of the multi-gigabyte folder
%ProgramFiles(x86)%\Android\android-sdk\

As this is still an issue with current Delphi versions: every now and then it looses which designers are needed for a frame:
[WayBack] What is the easiest way of getting Delphi to accept a newly added file as a frame and to treat it as such? – Stack Overflow (by Brian Frost)
<DCCReference Include="x\y\z\myFrame.pas"> <Form>frameMy</Form> <FormType>dfm</FormType> <DesignClass>TFrame</DesignClass> </DCCReference>
Then check your .dfm file to see if it starts with the correct inherited or object as per Delphi – TInterfacedDataModule revisted – use ‘inherited’ in your .dfm files when your datamodules look like forms in the designer.
Oh and at design time, be very careful embedding frames. Better not to do it at all and for certain: do not embed frames in a nested way: [WayBack] Frames in 10.2.2 Hi Has anyone else had issues with frames under 10.2.2? The project seems to have lost its links to the frames? If I went to the Too… – Vince Bartlett – Google+

This post is a reminder to myself that not all mappings from XSD to programming languages are possible.
There are many impossible cases, so this is just a general reminder.
A Delphi specific case for instance is the mapping of enumerations: one reason is that XSD enumerations are case sensitive, but the Delphi language is not: [WayBack] Using XML Enumerations with Delphi XML Data Binding Wizard – Stack Overflow.
More generic examples from my answer to the above question:
I’ve seen horrible things with wildcards that are sort of mappable to Java, but not to C#. This could likely go on for much longer…

Food for thought: what is the hardest thing in your sprints, why, can you make it less hard?
[WayBack] One Story Per “Sprint” – John Cutler – Medium:
Delivering a “potentially releasable increment” after N days is not “hard”. It is not rocket science. (Almost) any team can do it.
Via: [WayBack] One Story Per “Sprint” – John Cutler – Medium – Marjan Venema – Google+
it is not funny to always feel behind; that it actually is detrimental to productivity to focus solely on efficiency, working hard and being hero’s; that it might be a good idea to start with changing your perspective and doing something which has a chance of being successful (doing a single story) and build from there.
It is not about looking busy, but it is about getting things done without having any fears.

When you have physical access to a machine, assume it is compromised.
Sometimes the compromise can be as simple as a HID device access:

Reminder to self: [WayBack] Tomato by shibby – upgrade procedure and cfg backup | LinksysInfo.org:
I keep a text file with the changes I’ve made after a fresh install and I keep the file updated as I make changes.
Re-configuring the router after that takes a bit of time, but it is not that bad. Toastman’s method (here) noted above as well as the methods described here and here can also be used, but I haven’t tried them.
which references:
nvram export –set >config.txt
This outputs the complete setup in useable text form, each line beginning with “nvram set”. This means it’s ready to input to the router without having to add the “nvram set” to every line. You could do this by ssh or telnet.
NOTE – you can only restore the whole config file to the original router. To configure a different router you need to cherry pick the important lines (see below)
e.g.
nvram set clkfreq=480,240,120
nvram set wl0_country=AU
nvram set wan_domain=freewifi
nvram commit
