The IDEA project – an ongoing series of nonverbal algorithm assembly instructions

Posted by jpluimers on 2021/12/10

I wonder how many new algorithms were added, as the first 6 were really impressive: [WayBack] IDEA on Twitter: “Excited to announce the IDEA project – an ongoing series of nonverbal algorithm assembly instructions: https://t.co/zOAyfOAv3l… https://t.co/epQfBBdzdF”

While originally scheduling this, these were added:

Having cancer is not a fight or a battle, it is about having luck or misfortune

Posted by jpluimers on 2021/12/10

It has been a while after my last post about me having cancer. No, I am not giving up. But I am having the regular fear of the upcoming checks: did the metastases return, or do I have the luck to outlive some 30% of my peer group.

The last metastases surgery has been slightly more than a year ago. A year from now, that percentage hopefully will be 50% and slowly increase over time until about 90% in some 9 years from now.

At year’s end, I will know for sure.

Below are some links on, mostly Dutch but with English abstract, articles about the mental side of having cancer, or having survived it for now.

First/Last-Tab: Ctrl-1/9 (or Command-1/9): Switch Between Tabs in Any Browser Using Shortcut Keys

Posted by jpluimers on 2021/12/10

Only recently, I learned this works on just about any web-browser:

  • Ctrl-9 (macOS: Command-9) goes to LAST tab
  • Ctrl-1 (macOS: Command-1) goes go FIRST tab

Via: [WayBack] Switch Between Tabs in Any Browser Using Shortcut Keys

For those keyboard ninjas who hate using the mouse, switching between tabs in your browser window is essential since most people probably have a bunch of tabs open at once. […]

…

If you want to go to a specific tab, you can press CTRL + N, where N is a number between 1 and 8. Unfortunately, you can’t go past 8, so if you have more than eight tabs, you’ll have to use a different keyboard shortcut or just click on it. CTRL + 9 will take you to the last tab, even if there are more than 8!

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

It is supposed to work better than [Wayback] cmds/isoping.cc – 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: [Archive.is] 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: [Archive.is] Boris Veldhuijzen van Zanten on Twitter: “Or, next time you receive spam reply with this: “Please forward this email to bill@noprocurement.com, and delete my email, as I’ll be changing jobs soon, and this email address will no longer be active.””

The [Archive.is] 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 bill@noprocurement.com, 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 john@noprocurement.com

Jan Schaumann: “The secret language of coders, part N of many. Today: “risk acceptance”… “

From a while back, but more relevant than ever:

Obligatory video below the fold.

In case I ever need rails performance troubleshooting: I feel like I should be able to ask @datadoghq “What’s the CPU load across all our Rails controllers”, but have no idea where to start with that.

Posted by jpluimers on 2021/12/08

Just in case I need to do performance troubleshooting in Rails some day: [Archive.is] hey on Twitter: “@shelbyspees @honeycombio From a browser. Thinking is we had trouble even narrowing it down to a section of the site. Thinking if we could see that most of the load was in some_controller we could maybe dig in there. I don’t want to take up too much of your time, but how would a double request show up?” / Twitter

Chrome Print dialogue not offering fit to page, landscape, other printing options ( I’m looking at you @OHRA )

Posted by jpluimers on 2021/12/08

Some sites manage to disable various printing options (including layout, so you cannot choose between landscape and portrait any more, or force landscape when portrait works better or vice versa).

Googling this got me into a web of things that didn’t help me (see links below), but those led me to this query [Wayback] chrome save as pdf layout missing portrait landscape – Google Search.

That returned a helpful result at [Archive.is/Wayback] Chrome Print dialogue not offering fit to page, landscape, other printing options – Google Chrome Community:

I found a solution.

1.  Install the Stylus Extension.
2.  Go into the Stylus extension and click on “Write new style”.
3.  Put the following code in:
​​​@page {
  size: auto;
}

4.  Give it a name (I called mine “Fix Orientation”) and save it.

5.  Reload the page you’re trying to print and the print dialogue should now have the “Layout” option and you should always get it for any page you print from now on.

It’s about the extension [Archive.is] Stylus – Chrome Web Store

Redesign the web with Stylus, a user styles manager. Stylus allows you to easily install themes and skins for many popular sites.

I reconfigured the OHRA Mijn Zorg site to force re-enabling of layout by adding @page { size: auto !important; } for https://mijn.ohrazv.nl/ (click the Save button to save this change permanently):

Kristian Köhntopp on Twitter: “Playing with a Ceph Storage Volume in a VM: The new openstack backend provisions an all-flash Ceph volume, which after tuning delivers a commit latency of around 1.1ms or so”

Posted by jpluimers on 2021/12/07

Not on an average VM (8 threads and 16gb memory) or network (100gbit), but ceph isn’t average solution.

For my link archive this long Twitter thread:

Archive.is Kristian Köhntopp on Twitter: “Playing with a Ceph Storage Volume in a VM: The new openstack backend provisions an all-flash Ceph volume, which after tuning delivers a commit latency of around 1.1ms or so. My dev VM has 8 Threads and 16 GB of memory, and mounts the Ceph Volume with XFS in /a.”

Hopefully this one day makes into a blog post at [Wayback] Die wunderbare Welt von Isotopp | Something old, something new, something borrowed, something blue.
