Windows – WorldTransform on the Printer’s Canvas can be a challenge…

Posted by jpluimers on 2017/09/05

// Don't use SetWorldTransform [WayBack] on Printer.
// Some drivers don't handle it correct
// We will only use ModifyWorldTransform [WayBack]
// Let Windows and Driver do the Job

How to Easily Print a Large Image to Multiple Pages in Windows | Scottie’s Tech.Info

Posted by jpluimers on 2017/09/04

Many applications cannot not do that (Paint.net is one of them), but Paint can at least in Windows XP, 7, 8. and 8.1 (I need to check other Windows versions).:

In any case, here’s what you do:

  1. Open the image you’d like to print in Paint
  2. Select: Print -> Page Setup (Vista and 7), or File -> Page Setup (in XP)
  3. Under Scaling, select Fit to and change the setting to something like “3 by 2 page(s)”
  4. Click OK
  5. Print the image from Paint, and make sure to select “All Pages”

Note the “3 by 2” has the order “horizontal by vertical”.

How to change the Notepad++ editor’s font – via Notepad++ Community

Posted by jpluimers on 2017/09/04

Paraphrased Steps (thanks guy038); Screenshots below.

  1. Choose the menu option Settings  -> Style Configurator…
  2. In the Style configurator dialog, choose the Global Styles under Language
  3. Then, under Style, select the Default Style (this won’t work for Global Override unless you have that one override everything)
  4. Finally, in the Font Style area, you can select your favourite Font name and/or its Size and apearance (Bold, Italic, Underscore)
  5. Confirm with Save & Close when you like the new font settings.

The cool thing is that if you have a file open, you will immediately see the effects even before pressing Save & Close.

some notes on L2TP IPSEC on Mikrotik

Posted by jpluimers on 2017/09/01

For debugging purposes:

/log print where buffer=memory && (message~"l2tp" || message ~"L2TP"))

This will result in an answer like this:

13:43:59 l2tp,info first L2TP UDP packet received from 93.184.216.34
13:43:59 l2tp,ppp,info,account l2tp-jeroenp logged in, 192.168.73.239
13:43:59 l2tp,ppp,info <l2tp-l2tp-jeroenp>: authenticated
13:43:59 l2tp,ppp,info <l2tp-l2tp-jeroenp>: connecteda

Some links for when you cannot get connections to work:

Before digging deeper, check the output of settings like these:

/system logging add topics=ipsec

/ip ipsec policy group print
/ip ipsec peer print
/ip ipsec remote-peers print
/ip ipsec proposal print
/ip ipsec installed-sa print

It will give you answers like these (note that a Mac OS X 10.9.5 won’t connect with camelia encryption algorithms and not do better hashing than sha1):

> /ip ipsec policy group print
Flags: * - default
# NAME
0 * default

In order to switch away from default as Policy Template Group, you will have to:

  1. add a new IPSec group (in /ip ipsec policy group)
  2. add a new IPSec proposal (in /ip ipsec proposal) with the same PFS group name as the policy group.
  3. add a new IPSec policy (in /ip ipsec policy group) with (under General) the same group name as the policy group. *and* (under Action) the same proposal name as the proposal.

ESXi 6.5 Update 1: Anyone that knows how to edit the port groups of live VMs?

Posted by jpluimers on 2017/08/31

Anyone that knows how to edit the port groups of ESXi 6.5 Update 1 live VMs?

This worked fine in the C# based Windows vSphere Client, but not in the web-client.

When pressing Save, you get this error: Failed to reconfigure virtual machine [[vmname]]. The attempted operation cannot be performed in the current state (Powered on). - dismiss.

You have to edit because of This VM is attached to a network portgroup VM Network Fiber xs4all that doesn't exist. Edit this VM and attach it to a different network. Actions.

If seems a known issue at [Archive.is] ESXi Embedded Host Client – Bugs: #88 Error while editing a VM more than once, but it is unclear how these bugs are tracked and in which of the labs versions any of the bus are fixed ([Archive.is] @jpluimers: Hi @elesueur ! …How can we track progress at VMware Labs Flings?).

The big problem is that the vSphere Web Client is nearly covering the vSphere Windows Client, but as of VMware ESXi 6.5 update 1, the vSphere Windows Client cannot be used any more:

Screenshots:

Press Actions, then Edit Settings:

Press Save:

Delphi code completion but more relaxed

Posted by jpluimers on 2017/08/31

From my link archive:

Both via I remember someone in this group showed a prototype of a ‘code-completion’ replacement IDE expert, which supports fuzzy matching of method names you typed [WayBack]

If I remember correctly, the Kibitz compiler started to expose less functionality around the Delphi 7 or Galileo era rendering many of the GExperts additions useless. Not sure about the current state of that now.
