Sending SMS from your PC using a web browser through your Android Phone

Posted by jpluimers on 2019/03/29

I have been a long-time PushBullet user, but I bumped into an alternative if you just want to send SMS from a PC using a web browser through your Android Phone.

You will miss out all the other neat PushBullet features (like clipboard support), but it does work:

There is even a Mac warpper for it:

ESXi 6.5: mount a datastore that does not automount; esxcfg-volume to the rescue

Posted by jpluimers on 2019/03/29

I had a 1.5 TB SATA disk with VMFS5 created on ESXi 5.1 that would not want to mount on ESXi 6.5 automatically, not even after a rescan, or fresh boot, so I did this:

[root@ESXi-X10SRH-CF:~] esxcfg-volume --help

                                         its original copy is not online.

ssh from Mac OS X to ESXi: “WARNING: terminal is not fully functional”

Posted by jpluimers on 2019/03/29

When connecting from my Mac to my ESXi rig, some commands (especially less) show this output:

WARNING: terminal is not fully functional

So I created this alias to connect from my Mac to the internal address of my ESXi rig:

alias ssh-esxi-X10SRH-CF-internal='TERM=xterm ssh -p 22 root@'

The trick is the bold part: TERM=xterm (which you can also replace by export TERM=xterm; if you want future ssh sessions to use the same [wayback] TERM setting).

The reason is that the Mac defines the TERM variable as containing xterm-256 which is defined on the Mac itself, but ESXi has a hard time coping with it.

Some Mac OS and Xcode combinations had a problem with xterm-256 not being present ([WayBackmacos – Terminal strangeness after installing Xcode on Lion – Super User), but this isn’t the case on my system:

$ ls -alh `find /usr/share/terminfo | grep 'xterm-256color'`
-rw-r--r-- 1 root wheel 3.2K Jul 30 2016 /usr/share/terminfo/78/xterm-256color

On the Mac you really want to use xterm-256color as it looks way better than xterm-color or xterm: [WayBacklinux – What is the difference between xterm-color & xterm-256color? – Stack Overflow (thanks [WayBack] Chris Page!)

It seems I already did something similar on ESXi itself to get esxtop working: ESXi: when esxtop shows garbage. That was on the ESXi side and works as well for this problem too.

However, it is a bit harder to have a script run during ESXi boot time that sets this, so it is easier to fix this on the Mac side.

It works for all OS X and ESXi versions I’ve tested so far.

Not sure why, but sometimes the Delphi IDE does not allow you to toggle the Console Application; it looks off, but is in fact on: IsConsole returns true

Posted by jpluimers on 2019/03/28

On my research list: Not sure why, but sometimes the Delphi options display a regular application, but the IsConsole returns true because of AppType Console in the main PropertyGroup.

  1. console applications are turned off in the linker
  2. the debugger still shows it as a console application when stepping through the initialization section of the System unit

One of the problems is that unlike the {$APPTYPE directive (which has not changed much over time), the AppType element is undocumented (hardly anything in the .dproj file is documented).

The $APPTYPE lists two values: Console and GUI, defaulting to GUI:

Empirically, the AppType element can have these values:

  • Application
  • Console
  • Package

This is the topmost part of the .dproj file does not matter, without AppType element valued Console, or with it or even having it valued Application: either way a console application is being built.

There is no $APPTYPE in the .dpr or any of the .pas files.

The IsConsole variable is always false and a console window always appears when debugging.

That variable is not always conclusive, as there are situations where code is inside a BPL or DLL started by an EXE, so this works better: [WayBack] How to determine if I’m running as a console app? (Delphi on Win32) – Stack Overflow:

function IAmAConsoleApp: Boolean;
  Stdout: THandle;
  Stdout := GetStdHandle(Std_Output_Handle);
  Win32Check(Stdout <> Invalid_Handle_Value);
  Result := Stdout <> 0;

The .dproj files:

Windows Manifest Files and Delphi

Posted by jpluimers on 2019/03/28

An interesting read on Windows Manifest Files in Delphi [WayBack].


Do not let Delphi manage your manifest. All versions are either limited, or buggy, or both.

Basically it’s the same as doing VersionInfo in Delphi: do not let the IDE do it, but do it yourself. In this case:

Write your own manifest in XML, then load it as a resource.
