Only 2 weeks left to enable 2FA for your GitHub account

Posted by jpluimers on 2023/08/29

If you haven’t done so already, then enable 2FA for your GitHub account now: This will be a requirement in 2 weeks time.

The 2FA/MFA possibility started about half a year ago with [Wayback/Archive] Raising the bar for software security: GitHub 2FA begins March 13 – The GitHub Blog

You can have various means of 2FA, which al start with a choice between:

After completing either of those those, you can view/download a set of backup codes, and you can add more factors to your Multi-factor authentication setup up to these:

Email Handling and vBulletin Cloud – vBulletin Community Forum

Posted by jpluimers on 2023/08/25

For my link archive: [Wayback/Archive] Email Handling and vBulletin Cloud – vBulletin Community Forum.

  • Asking your end users to white list your email address and the Sendgrid IP (167.89.58.99) can help alleviate the issues.

I didn’t know the above but bumped into an issue because I didn’t know a supplier had moved to vBulletin Cloud, my account password stopped being accepted and my account password reset messages would not arrive.

So I wrote this as part of a mail to sort this out, and it was confirmed to be correct:

Then I re-checked a few connection refusals that appeared close to the password reset tries. Not sure if this a pattern, but a few of them had this:
2022-02-20T19:41:42.999415+01:00 snap sendmail[24314]: NOQUEUE: connect from o1678958x99.outbound-mail.sendgrid.net [167.89.58.99]
2022-02-20T19:41:43.015958+01:00 snap sendmail[24314]: NOQUEUE: dns 99.58.89.167.bl.spamcop.net. => 127.0.0.2
2022-02-20T19:41:43.016442+01:00 snap sendmail[24314]: ruleset=check_relay, arg1=o1678958x99.outbound-mail.sendgrid.net, arg2=127.0.0.2, relay=o1678958x99.outbound-mail.sendgrid.net [167.89.58.99], reject=553 5.3.0 Spam blocked see: http://spamcop.net/bl.shtml?167.89.58.99
2022-02-20T19:42:29.527789+01:00 snap sendmail[23814]: 21KIeTfo023814: engine10.uptimerobot.com [69.162.124.231] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
From the linked page I got to https://www.spamcop.net/w3m?action=blcheck&ip=167.89.58.99 indicating

167.89.58.99 listed in bl.spamcop.net (127.0.0.2)

If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 13 hours.

Causes of listing
  • System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)

Express-delisting is not available

Listing History

In the past 44.4 days, it has been listed 12 times for a total of 13.3 days

Can you check if the forum software uses sendgrid?

The confirmation linked to the first post in this blog entry on how to whitelist the SendGrid outgoing IP-address.

One thing I wonder: why does SendGrid use a single outgoing IP-address? If it gets blacklisted, many of their clients have problems.

Anyway: before adding the entry to my whitelist, the problem had resolved itself, and the blacklist entries were done:

Bruce Tate on Twitter: “What’s the most unique feature of your favorite programming language?”

Posted by jpluimers on 2023/08/24

For my link archive: [Wayback/Archive] Bruce Tate on Twitter: “What’s the most unique feature of your favorite programming language?” / Twitter

From the languages that I have been using most:

It was a kind of follow-up on his earlier tweet that also sparked nice responses at [Archive] Bruce Tate on Twitter: “What is a #programming technique or construct that other people like but you think is overused?” / Twitter.

In my respons I phrased my decades long pet peeve [Archive] Jeroen Wiert Pluimers on Twitter: “@redrapids OOP: inheritance over composition. This leads to deep hierarchies that eventually nobody understands.” / Twitter.

Whereas with OOP (object-oriented programming) one should use composition over inheritance, often the reverse is true.

Actually my take can be generalised into two directions as these hierarchies:

  1. often crowd a single namespace, so: crowding namespaces is bad.
    One does see this outside the Object Oriented realm a well.
  2. often have many levels of indirection, so: overdoing indirection is bad
    One does see this outside the Object Oriented realm a well, just not as pronounced.

Some notes on the WordPress Press-This bookmarklet

Posted by jpluimers on 2023/08/23

I want to improve my WordPress blogging experience especially since most of the pages I link also have two extra links of the archived pages in the Wayback Machine and Archive.is.

The WordPress Press-This bookmarklet does not always cut it. It is slow too as it does a POST request to the WordPress site which then renders a new page.

It is also highly minified, so below are some links that will hopefully allow me to research it further to see if I either could improve it for my own workflow, or need to start from scratch.

I want to figure out:

  • what the values of the v= version parameter were (I know about v=8 and v=4, there are likely more)
  • which commits were involved
  • can I get more information (like summary, first heading or first paragraph of a page too)
  • what techniques are used for opening new windows/tabs

TODO: make diffs of the various versions

Bookmarklet to save a page both in the WayBack machine and Archive.is (ending on the latter to solve a reCAPTCHA)

Posted by jpluimers on 2023/08/22

TL;DR:

javascript:{h=location.href;open('https://archive.is/?run=1&url='+encodeURIComponent(h));location.href='https://web.archive.org/save/'+(h)}

Burninator Sec: Twitter Removed the Blocked Account Export – Let’s Put it Back!

Posted by jpluimers on 2023/08/18

Hoping I can still use the Twitter API to perform thousands of requests: [Wayback/Archive] Burninator Sec: Twitter Removed the Blocked Account Export – Let’s Put it Back!

I dug around in the Data Archive and eventually found block.js, which is a JSON object of all the blocked accounts in their ideas. From there you can write a quick Python script to use the Twitter API to resolve all of those IDs to usernames.

Figuring out the threads for processes ran by python

Posted by jpluimers on 2023/08/17

A while ago I wrote about Figuring out the open network connections for processes ran by python, which explained the TL;DR:

pidof python | tr " " "\n" | xargs -r -n 1 lsof -i -a -e /run/user/1001/gvfs -p

Now I needed thread information as well, so below two examples using ps and pstree. I won’t explain the pidof and xargs stuff here as that was already covered in the above blog-post and I found out that ps already has a built-in way to filter on process name.

The ps solution uses the H, -L or -T argument to show the threads:

Youtube – Extract Meta Data – Amnesty International

Posted by jpluimers on 2023/08/16

Cool that Amnesty International can do a YouTube [Wayback/Archive] Extract Meta Data (Amnesty International).

I wonder if I can write a Bookmarklet for this (it will likely require an HTTP POST request).

Bookmarklet for Archive.is to navigate to the canonical link

Posted by jpluimers on 2023/08/15

This is a follow-up to Bookmarklets for Archive.is and the WayBack Machine to go to the original page.

Archive.is has two kinds of URLs:

  1. The encoded version is the short form without any meta-information,
  2. The canonical version is a long form and has metadata about Archive date and time, and the Archived URL,

You get the first URL both after archiving and when browsing from an archived page to another archived page (if it is not archived you will go the unarchived full page URL).
