The horrors of HTML email where there CSS

Posted by jpluimers on 2021/11/16

[Archive.is] Kat Maddox on Twitter: “Who’s the CEO of emails I need to talk to him… “:

This is why dreamweaver still exists.

[Archive.is] Kat Maddox on Twitter: “You don’t need a time machine to go back to the past. You just need to try to write HTML in emails. If I have to nest one more table, I’ll have gone back far enough to be able to warn people about the dot com bubble. Fuck it. I’m writing this newsletter in markdown”

Markdown with an HTML generator actually is quite a good way to get HTML emails going.

Another route is [Wayback] Foundation for Emails | A Responsive Email Framework from ZURB.

Oh remember this: [Archive.is] StuAngel on Twitter: “rule of thumb “the mail clients are about 5 years behind in HTML support” – that was like 10 years ago and they have never gotten any better… https://t.co/lVAW5YCubm”

unix/linux: using paste to turn separate lines into a comma separated list

Posted by jpluimers on 2021/11/16

Never to old to learn new things: I was totally unaware of the GNU paste tool that is available on virtually all unix/Linux/BSD core installs.

Thanks [WayBack] zeppelin for answering this question at [WayBack] linux – Turning separate lines into a comma separated list with quoted entries – Unix & Linux Stack Exchange:

You can add quotes with sed and then merge lines with paste, like that:

sed 's/^\|$/"/g'|paste -sd, -

If you are running a GNU coreutils based system (i.e. Linux), you can omit the trailing '-'.

If you input data has DOS-style line endings (as @phk suggested), you can modify the command as follows:

sed 's/\r//;s/^\|$/"/g'|paste -sd, -

Now I can get a comma separated list of for instance ssh available mac algorithms:

# ssh -Q mac | paste -sd, -
hmac-sha1,hmac-sha1-96,hmac-sha2-256,hmac-sha2-512,hmac-md5,hmac-md5-96,umac-64@openssh.com,umac-128@openssh.com,hmac-sha1-etm@openssh.com,hmac-sha1-96-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,hmac-md5-etm@openssh.com,hmac-md5-96-etm@openssh.com,umac-64-etm@openssh.com,umac-128-etm@openssh.com

To bypass a Chrome certificate/HSTS error, you can type ‘badidea’ (previously ‘thisisunsafe’) without quotes (this might change in the future)

Posted by jpluimers on 2021/11/11

For expired or self-signed certificates with an untrusted chain, you might want to by base the Chrome certificate/HSTS error message.

Instead of clicking a few times, you can also type ‘badidea’ (this used to be ‘thisisunsafe’ and might change again someday).

Based on: [WayBack] security – Does using ‘badidea’ or ‘thisisunsafe’ to bypass a Chrome certificate/HSTS error only apply for the current site? – Stack Overflow

Found via [WayBack] KPN-klanten kunnen Experiabox V10A niet benaderen door verlopen certificaat – Computer – Nieuws – Tweakers

Source code that handles this: [WayBack] components/security_interstitials/core/browser/resources/interstitial_v2.js – chromium/src – Git at Google

/**
 * This allows errors to be skippped by typing a secret phrase into the page.
 * @param {string} e The key that was just pressed.
 */
function handleKeypress(e) {
  var BYPASS_SEQUENCE = 'badidea';
  if (BYPASS_SEQUENCE.charCodeAt(keyPressState) == e.keyCode) {
    keyPressState++;
    if (keyPressState == BYPASS_SEQUENCE.length) {
      sendCommand(SecurityInterstitialCommandId.CMD_PROCEED);
      keyPressState = 0;
    }
  } else {
    keyPressState = 0;
  }
}

[MS-ERREF]: NTSTATUS Values | Microsoft Docs

Searching for Windows error codes (like the ones in blue screens) often leads to web-sites with an incomplete list.

Drawing with nice handwriting

Posted by jpluimers on 2021/11/10

Did you also wonder about the nice handwriting in the diagrams of yesterday’s post @adamsand0r drew up a few sketches of design decisions needed to be taken when building a #gitops-based CD pipeline « The Wiert Corner – irregular stream of stuff?

I did too.

They are from [Archive.is] Excalidraw | Hand-drawn look & feel • Collaborative • Secure, with source code at [Archive.is] GitHub – excalidraw/excalidraw: Virtual whiteboard for sketching hand-drawn like diagrams.

From a while back, but still relevant when you learn all your life:

[Archive.is] 🔎Julia Evans🔍 on Twitter: “ten questions about UDP: “

[WayBack] UDP questions

Hello! Here are some questions & answers. The goal isn’t to get all the questions “right”. Instead, the goal is to learn something! If you find a topic you’re interested in learning more about, I’d encourage you to look it up and learn more

/me is a 1x.engineer

Posted by jpluimers on 2021/11/09

It is totally OK to be an 1x engineer instead of a 10x engineer.

The link below shows why, what 1x engineers actually do and how much value they add.

[WayBack/Archive.is] 1x Engineer

The official website of 1x Engineers around the world.

If you have more to add to that list, feel free to add a pull request to the underlying repository: [WayBack/Archive.is] GitHub – cutenode/1x.engineer: The official website of 1x Engineers around the world

Some links on Delphi compiler potential speed improvements…

Posted by jpluimers on 2021/11/04

A long time ago, there was an interesting blog post referenced from [WayBack] See how you can use Delphi’s upcoming new language feature to improve performance of your code. – Erik van Bilsen – Google+ referred to [WayBack] Inline Variables can increase performance – grijjy blog which made me comment [WayBack] “given the potential performance improvements the compiler already could do, and how long they could have been done, I would not bet on these new improvements becoming reality anytime soon.” that I later backed up with these links:

One of the observations there is that since Delphi 2005, no major compiler speed improvements have been done, and that even between Delphi 5 and 2005 mot much has been done either.

From my point of view, the – not so big – Delphi compiler team is very busy keeping balls up in the air supporting the many compiler targets and architecture changes that have been introduced over the past decade or so, that they do not have resources to improve code generation other than rely on the LLVM tool chain (which is not used for Windows x86 and x64 development that covers like 90+% of the Delphi users).

In my book, when you need an “inline var”, you usually want to refactor that bit of code into a separate method anyway.

Refactoring out parts of code that have implicit try/finally blocks for managed variables or records is a strategy that can improve execution speed in many Delphi applications anyway, especially if that piece of code is outside of the happy flow: it moves unneeded overhead out of that flow.

This is actually a strategy used for instance in the Spring4D library: Stefan Glienke has a very good insight in how the compiler works and did magic to some performance critical code paths there.
