Splitting the ping

Posted by jpluimers on 2021/12/09

Cool tool that shows the asymmetric timing character of networks (usually because the send and receive paths are different): [Wayback] Splitting the ping

split-ping is a tool that can tell you what direction packet latency or loss is on. This is handy for network debugging and locating congestion.

The blog above explains the reason and details in great depth. Recommended reading.

Source code: [] benjojo/sping: Split ping, see what direction the loss or latency is on

It is supposed to work better than [Wayback] cmds/ – vendor/google/platform – Git at Google

 * Like ping, but sends packets isochronously (equally spaced in time) in
 * each direction.  By being clever, we can use the known timing of each
 * packet to determine, on a noisy network, which direction is dropping or
 * delaying packets and by how much.
 * Also unlike ping, this requires a server (ie. another copy of this
 * program) to be running on the remote end.

Threader is dying: save your content as soon as possible

Posted by jpluimers on 2021/12/09

Luckily I only had two posts using Threader, as I today learned that it is dying really soon now, as per [Wayback/Archive] Threader – Good Twitter threads every day (emphasis and archival links mine):

As part of this acquisition, we’ll be shutting Threader down on December 15, 2021.

We’ve [Wayback/Archive] recently built a similar reading experience at Twitter, which is now available as part of [Wayback/Archive] Twitter Blue.

All of our users will be able to export their bookmarks from their settings in our iOS and web apps. Make sure to also download your PDF archives if you’d like to keep them.

Twitter Blue is paid and only available in very few countries and is part of Twitter, so quite useless for archival.

The alternatives [Archive] @ThreadReaderApp, [Archive] @WayBackMachine and [Archive] @ArchiveIs for the win (:

Bye bye [Archive] Threader (previously [Archive] @Threader_app), it was fun while it lasted.

Playing around with spammers is easy

Posted by jpluimers on 2021/12/09

Thread start: [] Boris Veldhuijzen van Zanten on Twitter: “I created a fake company to play around with spammers, and it is just such a joy to use, and you can use it too. A thread: I receive an email from a scammer/spammer. Like this:… “

Archived unroll: [Wayback] Thread by @Boris on Thread Reader App – Thread Reader App.

Via: [] Boris Veldhuijzen van Zanten on Twitter: “Or, next time you receive spam reply with this: “Please forward this email to, and delete my email, as I’ll be changing jobs soon, and this email address will no longer be active.””

The [] inspiration partly came from [Wayback] The Story of Lenny, the Internet’s Favorite Telemarketing Troll:

Lenny is a decade-old chatbot designed to troll telemarketers that has developed a cult following online. It’s remarkably convincing, but is it actually effective?

Research indicated that Lenny is effective and wastes time of scammers which they cannot spend on calling real people.

Some highlights

Waste time by sending spammers in an auto-reply loop of personas.

“Please forward this email to, and delete my email, as I’ll be changing jobs soon, and this email address will no longer be active.”

One of the email forwards bounces:

There even is a (http-only) web-site [Wayback] Nordic Procurement Services – Providing Procurement services worldwide since 1994.

A plugin for gmail or other mail systems would be cool, just as having more domains and accounts:

Some people are already adding these to their own domains:

Be sure to spread the word.

Oh, and have some spammers contact
