MikroTik RB960PGS hEX PoE powering PoE devices: ensure you get a 48V power supply

Posted by jpluimers on 2021/08/24

By default, the [WayBack] MikroTik RB960PGS hEX PoE comes with a 24V power supply.

Most PoE capable devices cannot be powered by 24V but need 48V. I wrote about this before in the midst of the long post Linus Torvalds – Google+: Working gadgets: Ubiquiti UniFi collection (and a whole bunch of Unifi/Ubiquiti/Ubtn links)

So now I re-mention it in a much smaller post so it easier to find back, and a few links to Power over Ethernet – Wikipedia, where especially these bits are relevant:

  • The PoE Standard implementation for 802.3af (802.3at Type 1) “PoE” requires DC 44.0–57.0 V.
  • Of the PoE Non-standard_implementations, some common Passive specifications include:
    • 24VDC 0.5A 100 Mbit/s or 1 Gbit/s
    • 24VDC 1.0A 100 Mbit/s or 1 Gbit/s
    • 48VDC 1.0A 100 Mbit/s or 1 Gbit/s
    • 56VDC 1.0A and 2.0A 1 Gbit/s (used for 45W+ load point to point microwave and millimeter band radios

The 24V is what MikroTik sticks to with their default power supply.

Windows 10: quickly view Settings -> Printers no matter the installed language

Posted by jpluimers on 2021/08/23

From Windows 8 on, Microsoft has been pushing more and more stuff to the App UI (sometimes called Immersive User Interface).

By default they are only easily accessible from the search feature from the “Start” button or “Search” pane in the task bar.

This is cumbersome or even problematic when you have to remember the correct terms over many localisations.

In the past you could run this from the command prompt or Windows+R keyboard shortcut “Run” pop-up:

control printers

This does not work however in either of the two:

settings printers

This works from the Windows+R keyboard shortcut “Run” pop-up:

ms-settings:printers

This works from the command prompt:

start ms-settings:printers

The difference is that with control , it will eventually find control.exe on the path, but ms-settings: is the scheme bit of an URI. The start command can handle this, the plain command-line cannot.

What in fact happens is that the URI scheme handler, will have a Windows Service (which runs under NT AUTHORITY\SYSTEM) start "C:\Windows\ImmersiveControlPanel\SystemSettings.exe" -ServerName:microsoft.windows.immersivecontrolpanel under your current user.

List of Settings URIs

Next to a List of applications behind the various control panel links – via “Stop user access to control panel”, below is a list of Settings URIs.

The below list is from [WayBack] The list of Settings pages URIs (ms-settings) in Windows 10 , but misses ms-settings:printers.

The Windows key has no Unicode equivalent, so use ⊞ like Wikipedia and many others do

Posted by jpluimers on 2021/08/23

lFor Mac keyboard keys, almost all (except the old solid and open Apple logo’s) have a Unicode code point, see for instance the modifier keys from the [WayBack] List of Mac/Apple keyboard symbols · GitHub (the “Alt” column has a solid Apple logo in the bottom right; on non-Mac systems it will look differently as it is in the Unicode private range: [WayBack] Unicode Character ” (U+F8FF): ‘<Private Use, Last>’):

Sym Key Alt

These are the code points for the “Sym” column:

Windows chocolatey Wireshark install: ensure you install nmap too, so you have a pcap interface for capturing!

Posted by jpluimers on 2021/08/19

Wireshark is indispensable when doing network communications development or DevOps.

This is my choco-install-network-tools.bat batch file to install Wireshark and the pcap dependency which nmap provides:

choco install --yes nmap
:: wireshark requires a pcap for capturing; nmap comes with npcap which fulfills this dependency
:: see:
:: - https://chocolatey.org/packages/wireshark
:: - https://chocolatey.org/packages/win10pcap
:: - https://chocolatey.org/packages/WinPcap
:: - https://chocolatey.org/packages/nmap
choco install --yes wireshark

Yes, I know: Windows Subsystem for Linux could have an easier installation, but the above:

A storage history thread by @Foone: from USB Floppy drive back to Shugart via UFI/ATAPI/SCSI and everything in between

Posted by jpluimers on 2021/08/19

Quite some interesting bits in [WayBack] Thread by @Foone: “So if you want to use a USB floppy drive, you use a USB protocol called the UFI: Uniform Floppy Interface. What’s UFI? A way to embed ATAPI […]”

Via [WayBack] Kristian Köhntopp on Twitter: “PC Hard drive and floppy disk interfaces, and the people and companies that made them.”

html – How can I scale the content of an iframe? – Stack Overflow

Posted by jpluimers on 2021/08/19

I used [WayBack] html – How can I scale the content of an iframe? – Stack Overflow as starting point to scale some iframes.

In my case, I had to scale up (by a 25% so a factor 1.25) instead of scale down.

What I observed so far in recent Chrome versions is:

  1. The wrapping div is still needed, otherwise the outer size and inner size of the frame mismatches
  2. The wrapping div and the wrapped iframe need to have the same dimensions (so unlike the Stack Overflow answers, no need to scale the width/height of the div; keep the same values as the iframe)

The div uses class calendar_wrap.

The iframe uses class calendar_iframe.

This is part of my CSS:

body {
      margin: 0; /* override browser setting for body `margin: 8px;` */
      overflow: hidden; /* remove scroll bars; does not work for iframes  */
    }

    /* ... */

    iframe {
      border-width: 0; /* override browser setting for iframe `border-width: 2px; */
      height: 100vh;
      width:   50vw;
      overflow: hidden; /* remove scroll bars; does not work for iframes  */
    }

     /* wrap and iframe zoom as per https://stackoverflow.com/questions/166160/how-can-i-scale-the-content-of-an-iframe */
    .calendar_wrap {
      float: left;

      height: 70vh;
      width:  35vw; /* calc(35vw / 1.25); */

      padding: 0;
      background-color: blue;
    }

    .calendar_iframe {
      float: left;

      width:  35vw;

      -ms-transform: scale(1.25);
      -moz-transform: scale(1.25);
      -o-transform: scale(1.25);
      -webkit-transform: scale(1.25);
      transform: scale(1.25);

      -ms-transform-origin: 0 0;
      -moz-transform-origin: 0 0;
      -o-transform-origin: 0 0;
      -webkit-transform-origin: 0 0;
      transform-origin: 0 0;
    }

    /* ... */
