Some @MCH2022Camp badge updates I found on Twitter

Posted by jpluimers on 2022/07/19

For all attending [Wayback/Archive] May Contain Hackers 2022 , a few things to check out:

  • their blog contains new posts with exiting news: [Wayback/Archive] Weblog | May Contain Hackers 2022 – blog
  • Tweeps and tweep-groups are fiddling with the MCH2022 badge already resulting in cool things like:
    • The MCH2022 terrain as a gameboy map (which runs on the MCH2022 badge)
    • There is a batch housing you can 3D print
    • Thumb knobs for the MCH2022 badge to it is easier on your fingers (2 models)
    • More software to run on the MCH2022 badge (like a CTF game)
    • Doom running on the badge (that of course was just a matter of time)
    • After MCH2022 there are 3 more hackercamps in Europe

More below…

Viewing the most recent Windows DNS requests on the console

Posted by jpluimers on 2022/07/18

I missed that over time, ipconfig has been extended with some more commands.

The command ipconfig /displaydns does exaxctly what I want: Display the contents of the DNS Resolver Cache.

The ipconfig help:

USAGE:
    ipconfig [/allcompartments] [/? | /all |
                                 /renew [adapter] | /release [adapter] |
                                 /renew6 [adapter] | /release6 [adapter] |
                                 /flushdns | /displaydns | /registerdns |
                                 /showclassid adapter |
                                 /setclassid adapter [classid] |
                                 /showclassid6 adapter |
                                 /setclassid6 adapter [classid] ]

where
    adapter             Connection name
                       (wildcard characters * and ? allowed, see examples)

    Options:
       /?               Display this help message
       /all             Display full configuration information.
       /release         Release the IPv4 address for the specified adapter.
       /release6        Release the IPv6 address for the specified adapter.
       /renew           Renew the IPv4 address for the specified adapter.
       /renew6          Renew the IPv6 address for the specified adapter.
       /flushdns        Purges the DNS Resolver cache.
       /registerdns     Refreshes all DHCP leases and re-registers DNS names
       /displaydns      Display the contents of the DNS Resolver Cache.
       /showclassid     Displays all the dhcp class IDs allowed for adapter.
       /setclassid      Modifies the dhcp class id.
       /showclassid6    Displays all the IPv6 DHCP class IDs allowed for adapter.
       /setclassid6     Modifies the IPv6 DHCP class id.


The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid and Setclassid6, if no ClassId is specified, then the ClassId is removed.

Examples:
    > ipconfig                       ... Show information
    > ipconfig /all                  ... Show detailed information
    > ipconfig /renew                ... renew all adapters
    > ipconfig /renew EL*            ... renew any connection that has its
                                         name starting with EL
    > ipconfig /release *Con*        ... release all matching connections,
                                         eg. "Wired Ethernet Connection 1" or
                                             "Wired Ethernet Connection 2"
    > ipconfig /allcompartments      ... Show information about all
                                         compartments
    > ipconfig /allcompartments /all ... Show detailed information about all
                                         compartments

Automatically reload page in Chrome without plugin – Super User

Posted by jpluimers on 2022/07/14

Below is a cool solution to refresh a page using a bookmarklet is to embed it into an iframe, then automatically reload it every interval.

It for instance works for the [Wayback/Archive.is] Woonveilig and often in Fritz!Box environments.

[Wayback] Jon described the below method as a solution for his own question, 6 years after asking it in [Wayback/Archive.is] Automatically reload page in Chrome without plugin – Super User.

So I made this a bookmark:


javascript:document.getElementsByTagName("body")[0].innerHTML = "<iframe id=\"testFrame\" src=\""+window.location.toString()+"\" style=\"position: absolute; top:0; left:0; right:0; bottom:0; width:100%; height:100%;\"><\/iframe>";reloadTimer = setInterval(function(){ document.getElementById("testFrame").src=document.getElementById("testFrame").src },5*60*1000)

(it is in a gist as the WordPress editors keep killing the embedded html code, despite it being escaped within <code> tags.

The Delphi and Turbo Pascal tools page by Duncan Murdoch has moved domain from www8.pair.com to murdoch-sutherland.com

Posted by jpluimers on 2022/07/13

For a very long time (about 2 decades) Duncan Murdoch had his home page at www8.pair.com/dmurdoch which somewhere in 2021 has moved to

I figured that out thanks to some help from [Wayback/Archive] Pair Networks (@pairnetworks) / Twitter.

So you need to do a replacement of many URL link prefixes

  • from http://www8.pair.com/dmurdoch/
  • to: http://murdoch-sutherland.com/

For instance some old and new pages:

GitKon Sept 22 – 23, 2021 – Virtual Git Conference | Presented by GitKraken

Posted by jpluimers on 2022/07/12

GitKon was a cool virtual conference about git and the git ecosystem: [Wayback/Archive.is] GitKon Sept 22 – 23, 2021 – Virtual Git Conference | Presented by GitKraken

Navigation was a bit hard because of the visual overload on the site (look at the various Archive.is archivals), so here is the outlined list of sessions with the rough timestamps in the below live recordings:

Global sitemap:

Live recordings are below. Hopefully they will last and per session splits will have become available.

None of them are at listed at [Wayback/Archive.is] www.youtube.com/c/Gitkraken/videos.

Last days until the May Contain Hackers 2022 camp; the badge project can still use some help on the software side: Python apps, FPGA, documentation, etc

Posted by jpluimers on 2022/07/11

After yesterdays post (which I will be editing to add some more pictures) MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp) now a call for help:

The Badge Team needs volunteers helping them on the software side.

At the badge event, the version 1.0 firmware was flashed so the badge will function perfectly fine during the event, but it would be cool if more features are available that attendees can get when upgrading at the event or downloading from the hatchery.

There is a virtual environment to test and a GitHub projects page with open issues to get started.

See the links below on how you can help:

MCH2022 badge sneak previews from tweeps that attended the Bitlair 20220709 Sweatshop (@MCH2022Camp)

Posted by jpluimers on 2022/07/10

The MCH2022 badge has an ESP32 (with WiFi!), a RP2040 and an FPGA next to a full colour TFT LCD, buttons (including joystick!), LEDs, LiPo battery, USB-C connector, micro SD-card slot and more (see below) and SHA2017 badge compatibility. How cool is that!

There is a wealth on information for this at [Wayback/Archive] Badge.team (some 22 repositories and counting: [Wayback/Archive] Badge.team: search for repositories containing mch2022).

Good starts are [Wayback/Archive] MCH2022 badge | BADGE.TEAM and [Wayback/Archive] Software Development | BADGE.TEAM (yes of course you can write your own software for it and even distribute it through the [Wayback/Archive] hatchery.badge.team Hatchery).

Below are lots of tweets including some of the Twitter retrospect that organically grew (just like the sweatschop event) on Twitter the day after.

From the original announcement [Wayback/Archive] May Contain Hackers 2022: Presenting: The MCH2022 badge! , this is what hardware is in it

HTTPS Is Actually Everywhere | Electronic Frontier Foundation (so HTTPS everywhere will sunset January 2023)

Posted by jpluimers on 2022/07/08

I missed this announcement: [Wayback/Archive] HTTPS Is Actually Everywhere | Electronic Frontier Foundation.

Though in practice there still are a few sites not having HTTPS (usually old blogs, sometimes old forums too), almost all have (thanks Let’s Encrypt!) and many not even support HTTP any more.

So the HTTPS Extension in Google Chrome recently pointed me to [Wayback/Archive] Set Up HTTPS by Default in Your Browser | Electronic Frontier Foundation, which pointed me to the above post, which taugt me that most browsers (Firefox, Chrome, Edge and Safari) by now have an HTTPS-only mode which you can enable by hand or sometimes is just the only way.

Cool, I love progress!
