Twitter wayback_exe generates screenshots of old websites in old browsers every two hours

Posted by jpluimers on 2021/12/22

Classic browsers

Classic browsers

Going back to in time old web-pages using old web-browsers is fun!

[Archive.is] wayback_exe (@wayback_exe) | Twitter automatically does it for you.

A short introduction is at [Wayback] muffinlabs – @wayback_exe.

There is a playground at [Archive.is] oldweb.today where you can choose which classic browser to use for viewing and what page to view with it.

You can fiddle around with the node.js based code that is available on GitHub: [Wayback/Archive.is] muffinista/wayback_exe: code for twitter bot @wayback_exe

Some screenshots:

Some notes on forwardemail.net

Posted by jpluimers on 2021/12/01

Some notes, as I’m looking to a stable, simple to maintain email forwarding system that is also secure and – yes – can cost money.

I need to leave IT-infrastructure behind that is easy to maintain for my heirs.

Some links:

  • [Archive.is] mausdompteur 💉 on Twitter: “Email! Yes, Email. Need to Set Email for a domain, basically forward only. Has anyone ever heard of https://t.co/v29TbMXrrl? Is it good? Any alternatives I should consider?”
  • [Wayback] The Best Free Email Forwarding Service for Custom Domains | Forward Email

    The best open-source and free email forwarding service for custom domains. We do not keep logs nor store emails. We don’t track you. Unlimited aliases, catch-alls, wildcards, API access, and disposable addresses. Built-in support for DKIM, SRS, SPF, ARC, DMARC, and more. No credit card required.

  • [Wayback] FAQ | Forward Email has a truckload of information, but the main points for me are these:

    What is the max email size limit

    We default to a 50MB size limit, which includes content, headers, and attachments. Note that services such as Gmail and Outlook allow only 25MB size limit, and if you exceed the limit when sending to addresses at those providers you will receive an error message.

    An error with the proper response code is returned if the file size limit is exceeded.

    …

    What is the difference between Free and Enhanced Protection

    The Free plan requires you to use public DNS records to store your forwarding configuration. Anyone with a computer can lookup your forwarding configuration in a terminal if you are on the Free plan. Unlike the Free plan, the Enhanced Protection plan uses a cryptographically generated random string to store your forwarding configuration privately.

    Free Plan Enhanced Protection Plan
    forward-email=user@gmail.com forward-email-site-verification=m8d7o8K4Il
  • [Wayback] About | Forward Email with this very important point for me:

    Privacy

    We have a “zero tolerance policy” privacy policy, which states that we don’t store logs nor emails, and we don’t track users. Our statement clearly states that we do not collect nor store forwarded emails, metadata, server-side nor client-side logs, IP addresses, or browser information.

    Only an email address is required to create and configure the Enhanced Protection Plan, which hides DNS email alias information on the free plan through a managed and hosted service.

    User’s accounts, domains, and all related information can be permanently deleted at any time by the user.

  • [Wayback] Pricing | Forward Email (levels: free / enhanced protection / team / enterprise)

    Free email forwarding for domains with features including Custom Domain Email Forwarding, Disposable Addresses, Multiple Recipients, Wildcards, and more!

  • It’s open source too (written in JavaScript using Node.js), but running it requires you to keep up with versions and security: [Wayback/Archive.is] forwardemail/free-email-forwarding: The best free email forwarding for custom domains. Visit our website to get started (SMTP server)

Random User Generator | Home

Posted by jpluimers on 2021/11/23

Cool tool for when you ever need random users to test a system [Wayback] Random User Generator | Home:

Random user generator is a FREE API for generating placeholder user information. Get profile photos, names, and more. It’s like Lorem Ipsum, for people.

This was used when extracting Parler data to substantiate evidence around the 20210106 USA Capitol riots.

You can even use a simple HTTP GET like [Wayback] randomuser.me/api and get a JSON result like this.

{"results":[{"gender":"female","name":{"title":"Miss","first":"Malou","last":"Mortensen"},"location":{"street":{"number":2669,"name":"Lyngbyvej"},"city":"Sundby","state":"Syddanmark","country":"Denmark","postcode":48047,"coordinates":{"latitude":"-35.1307","longitude":"113.7480"},"timezone":{"offset":"+1:00","description":"Brussels, Copenhagen, Madrid, Paris"}},"email":"malou.mortensen@example.com","login":{"uuid":"981747de-66fe-40b0-87ea-adfe403fe1be","username":"purpleostrich871","password":"sweets","salt":"x86aQbIB","md5":"55497ac53530b428f98b9d36267ceeef","sha1":"358b94ffabe7d827c34da15791e5d6717c594428","sha256":"6e357e887877e29b7e6d53073f648174382c53c24f83479e25fed9c82075ed32"},"dob":{"date":"1995-06-05T04:50:35.145Z","age":26},"registered":{"date":"2018-07-21T00:59:50.523Z","age":3},"phone":"02990797","cell":"94800012","id":{"name":"CPR","value":"050695-9954"},"picture":{"large":"https://randomuser.me/api/portraits/women/27.jpg","medium":"https://randomuser.me/api/portraits/med/women/27.jpg","thumbnail":"https://randomuser.me/api/portraits/thumb/women/27.jpg"},"nat":"DK"}],"info":{"seed":"8971869bb62b73d7","results":1,"page":1,"version":"1.3"}}

GitHub’s commitment to npm ecosystem security | The GitHub Blog – no npm package can historically ben tracked to be authentic

Posted by jpluimers on 2021/11/18

What started as [Wayback/Archive] GitHub’s commitment to npm ecosystem security | The GitHub Blog with this qoute:

on November 2 we received a report to our [Wayback/Archive] security bug bounty program of a vulnerability that would allow an attacker to publish new versions of any npm package using an account without proper authorization. …

This vulnerability existed in the npm registry beyond the timeframe for which we have telemetry to determine whether it has ever been exploited maliciously. … the timeframe for which we have available telemetry, which goes back to September 2020 …

This basically means you cannot trust the authenticity of any npm package published through the registry.

It sparked reactions like these:

For my link archive:

I also need to check out [WayBack] Martin Farach-Colton – Wikipedia, as his algorithm is likely more optimised and more versatile.

For WiFi guest networks with a fixed SSID: QR code – Wikipedia

Posted by jpluimers on 2021/10/06

Access Denied

Access Denied

I knew it was possible to generate QR codes to access quest networks (as the QR code has credentials) for WiFi networks having a fixed SSID.

I just never bothered, but did when needed home care with quite a few different people providing the care.

Generating was easier than I anticipated, though I hoped I just could put the parameters in a URL and fire off to get a page including the QR code.

Alas, the pages I found require you to enter the SSID name and key/password phrase.

That’s OK: I have saved the PNG files for our network and my brother’s as images so I can put them on-line, and printed them out so guests can scan and use the network at once.

Here we go:

  • 124 network Access Denied, key 2171TB24
  • 171 network Disconnected, key 1060NP71

GitHub – metasfresh/metasfresh: We do Open Source ERP – Fast, Flexible & Free Software to scale your Business.

Posted by jpluimers on 2021/09/22

For my link archive: [WayBack] GitHub – metasfresh/metasfresh: We do Open Source ERP – Fast, Flexible & Free Software to scale your Business.

It’s mainly written in JavaScript and Java with a PostgreSQL database and elasticsearch search.

There is plenty of [WayBack] metasfresh documentation (for users, administrators and developers), all with markdown source.

The developer documentation starts with a nice diagram of the [WayBack] metasfresh Architecture:

Markdown source of the architecture page: [WayBack] metasfresh-documentation/metasfresh_architecture.md at gh-pages · metasfresh/metasfresh-documentation · GitHub: Docs and Manuals for Devs, Users, Admins.

So here are some links for my archive:

Where my tweet about testing in production gained me knowledge about the Covid QR code systems

Posted by jpluimers on 2021/07/06

Even though RIVM twitter-care did not respond at all on my raised issue that the production environment leaded an acceptation environment URL, it did gain me some knowledge on their systems and the (then upcoming) European QR code systems.

[Archive.is] Jeroen Wiert Pluimers on Twitter: “Onhandig op de #CoronaCheck site van het @rivm de link hier (1) wijst nog naar de acceptatie omgeving en daar heb je authorisatie voor nodig. Zonder “.acc” werkt het ook niet: (2) Dit werkt wel: (3) CC @locuta… “

  1. web.acc.coronacheck.nl/nl/faq/1-6-welke-informatie-staat-in-mijn-qr-code/
  2. web.coronacheck.nl/nl/faq/1-6-welke-informatie-staat-in-mijn-qr-code/
  3. coronacheck.nl/nl/faq/1-6-welke-informatie-staat-in-mijn-qr-code/

The problem digging into it was that it only reproduces when inside the [Archive.is] Coronacheck Print Portaal after you have logged on via DigiD, so you cannot save it in the WayBack machine nor Archive.is.

This print portal isn’t a straightforward hierarchy of web-pages, but an actual Vue.js app that injects itself into [Wayback/Archive.is] nl-covid19-coronacheck-website/index.html at main · minvws/nl-covid19-coronacheck-website and dynamically changes the URL depending on the application state.

It also means that you cannot archive pages like coronacheck.nl/nl/print/vaccinatie-ophalen or coronacheck.nl/nl/print/keuze-papieren-bewijs as the Vue.js app will not understand state from those sub-URLs and go back to coronacheck.nl/nl/print/

The only other results of [Wayback] “acc.coronacheck.nl” – Google Search were:

Acceptance URLs in production

I had a hunch the CoronaCheck code would be open source, though finding it through the most obvious [Wayback] open source coronacheck app – Google Search failed. Since the web-site and app look very similar to the CoronaMelder web-site and app, I tried [Wayback] open source coronamelder app – Google Search and found the page with links: [Wayback] Colophon – Stop the spread of the coronavirus, download CoronaMelder.

Note that [Wayback] Open-Source Project Corona-Warn-App is a different beast. Though internationally available and released way earlier than the Dutch apps, the Dutch government has a huge ego (maybe even abbreviatable to Hugo) resulting in severe “not invented here” syndrome despite having had to be bailed out when “code black” happened in hospitals.

One thing that I learned is that there is one version of the code behind coronacheck.nl/nl/print/print-vaccinatie in the main branch of github.com/minvws/nl-covid19-coronacheck-website that has only acceptance URLs. They are in these locations:

Apparently, replacing these with production URLs is done during deployment, but I could not find the code that does it in the main repositories at [Wayback] github.com/minvws

European Corona/COVID-19 Green Pass QR certificate

One answer to my tweet was [Archive.is] Joel Haasnoot on Twitter: “gir.st/blog/greenpass.html… “ which provides more information on the European

These are the links I thought were interesting:
