It was fitting to bump into [WayBack] Packet Sender is a good tool when debugging protocols…” Written by Dan Nagle… – Lars Fosdal – Google+ on the day presenting [WayBack] Conferences/Network-Protocol-Security.rst at master · jpluimers/Conferences · GitHub
It also means that libssh2-delphi is getting a bit more love soon and will move to github as well after a conversion from mercurial.
Some of the things I learned or got confirmed teaching the session (I love learning by teaching):
Here is some more info:

Not just a great overview for the season, but also a good overview on what the state of the art in various SSD products is: [WayBack] Best SSDs: Holiday 2017.

A kind of repeat of a 6 year old post, as by now this has much more information: [WayBack] hardware rec – When to stop using a hard drive? What rules/software apply? – Super User.
It is a continuation for another drive of my 2011 post hard drive – When to stop using a HDD? What rules/software apply?.
Basically I was unlucky receiving a brand new drive that appeared exceptionally slow and doing some ticking.
So I ran these on it:

Sorry for the “missed schedule”, but WordPress.com is acting up again:

Since I ran this machine on Windows and I didn’t have time to run locally, these are the tools I used:

The SuperMicro X10SRI-F and X10SL7-F boards are very similar, so I was happy that [WayBack] SuperMicro X10SL7-F – Onboard LSI pointed out where the CPU fan was: it’s header FANA which isn’t exactly clear form the X10SRI-F motherboard PDF manual [WayBack]:
FANA is the CPU fan connector
(I connected my CPU fan to the closest fan connector and everything works like a charm, but I’m still curious).

Mikrotik and SFP versus SFTP+ is always confusing especially as the text on their equipment and their documentation doesn’t show well which situations work.
Equipment text is further on, this is their text searchable documentation:
As usually, a long search in the forums reveals the background information:
[WayBack] SFP in SFP+ slot – MikroTik RouterOS: 10Gb SFP+ sockets are usually backward compatible with SFP, but this is not guaranteed.
There are two tricks involved to get an SFP connection between these devices working:

Maybe for my LoT (LAN of Things): having multiple (even many) local LANs some each with their section of LoT equipment nicely separated and partially being able to talk to some of the other LANs or part of the outside world.
Some links that might help me getting this set up:
The basic plan:
- Configure each port or grouped (with ethernet master-port or maybe bridged) of ports having their own address pool and DHCP server so each of them are in a separate private network
- Routes between the networks so they can be accessed
- NAT mangling so the networks can reach the other networks or outside world without exposing their private network addresses
- Firewall rules to permit/limit which networks can see each other or the outside world
WinBox displays routes in various colors [WayBack]:
- Black – active
- Blue – inactive
- interface not up or disconnected
- other route with higher precedence already covers this route
- Red – invalid
- interface does not exist
- interface is disabled
- IP address not on that interface any more
Sometimes they show as blue while still being legitimate. Not sure why yet.

Accessibiity -> Zoom -> enable checkbox” class=”size-medium” /> Preferences -> Accessibiity -> Zoom -> enable checkbox
I didn’t know this was built-in since Mountain Lion and up, but it is, is startable from the keyboard and it’s tremendously convenient when presenting: [WayBack]: OS X Mountain Lion: Zoom content on the screen.
TL;DR:
- System Prefrecences
- Accesibility
- Zoom
- Checkbox
