DNS Checker – DNS Check Propagation Tool

Posted by jpluimers on 2024/05/24

Not that long ago I learned about [Wayback/Archive] DNS Checker – DNS Check Propagation Tool:

CHECK DNS PROPAGATION

Recently changed your DNS records, switched web host, or started a new website: then you are at the right place! DNS Checker provides a free DNS lookup service to check Domain Name System records against a selected list of DNS servers located in multiple regions worldwide. Perform a quick DNS propagation lookup for any hostname, and check DNS data collected from all available DNS Servers to confirm that the DNS records are fully propagated.

I wish I had known it before as it is a great tool to verify DNS lookups from around the world.

For my link archive (A and SOA records are the most important to me):

Script alternatives to the Windows-L keyboard shortcut (SwitchUser / LockWorkstation)

Posted by jpluimers on 2024/05/23

More than a decade ago I wrote about Programmatic alternatives to Windows-L keyboard shortcut (SwitchUser / LockWorkstation).

Still, I see many scripts invoke rundll32.exe or to call the [Wayback/Archive] LockWorkStation function (winuser.h) inside user32.dll. Don’t!

The BOOL LockWorkStation()function has a calling convention that is incompatible with rundll32.exe () which will corrupt the call stack likely will lead to random problems as after two decades, this post from Raymond Chen still holds: [Wayback/Archive] What can go wrong when you mismatch the calling convention? – The Old New Thing

Lots of interesting git links via b0rk on Twitter

Posted by jpluimers on 2024/05/22

A few years back [Wayback/Archive] 🔎Julia Evans🔍 (@b0rk) / Twitter asked for tips on learning git which resulted in a wealth of resources.

    - ad a summary at [Wayback/Archive] TL;DR // Think Like (a) Git:
      Git is an incredibly powerful tool, but it can be hard to learn.
      
      It helps to know something about [Wayback/Archive] graph theory, especially with regard to [Wayback/Archive] reachability.
      
      And to know what Git’s [Wayback/Archive] references are.
      
      Because [Wayback/Archive] references make commits reachable.
      (Only got time to read one page? Make it that one.)
      
      Once you understand that, you won’t waste so much time backing up your entire repository, [Wayback/Archive] like I did.
      
      [Wayback/Archive] I like GitX, and you can use it (or another visualizer) to bootstrap your knowledge of Git.
      
      I’ve got a few recipes for [Wayback/Archive] testing out merges that give you an “undo” option.
      
      And I’ve attempted to explain [ Wayback/Archive] rebase as simply as I can.
    - [Wayback/Archive] Resources // Think Like (a) Git pointing to a lot of information and to useful tools like:
      - [Wayback/Archive] jonas/tig: Text-mode interface for git with documentation at [Wayback/Archive] Introduction · Tig – Text-mode interface for Git (which used to be at [Wayback/Archive] Index of /tig)
      - [Wayback/Archive] The Thing About Git
        
        The Index is also sometimes referred to as The Staging Area, which makes for a much better conceptual label in this case. I tend to think of it as the next patch: you build it up interactively with changes from your working copy and can later review and revise it. When you’re happy with what you have lined up in the staging area, which basically amounts to a diff, you commit it. And because your commits are no longer bound directly to what’s in your working copy, you’re free to stage individual pieces on a file-by-file, hunk-by-hunk basis.
        
        …
        
        git add --patch is actually a shortcut to features in git add --interactive, a powerful front-end for managing all aspects of the staging area.
        
        git commit --amend takes the changes staged in the index and squashes them into the previous commit.
        
        And then there’s git rebase --interactive, which is a bit like git commit --amend hopped up on acid and holding a chainsaw…
        
        People seem to get a lot of utility out of git-stash(1), which lets you move changes from your working copy into a lightweight holding area to be reintroduced some time later.

Later I want to categorise all these, maybe using categories like these:

Videos
Stories/narrations
Levels (beginner/intermediate/advance)
Direction (inside-out vs outside-in)
(Rough) reimplementations
Perspectives from different version control systems
Failures: learning from or preventing them

I need to contemplate about that for a while.

Watch “Felienne Hermans: How patterns in variable names can make code easier to read” on YouTube

Posted by jpluimers on 2024/05/21

A while ago, various sources pointed me to the great video below by [Wayback/Archive] Felienne Hermans: How patterns in variable names can make code easier to read – YouTube.

I responded to the first Tweet with a series of tweets describing my two pet-peeves that I see going wrong when teaching new programmers how to name things (the examples are in Delphi, but I have seen similar shortcuts being taken in C#, VB.NET, and JavaScript being taught in both courses and conference sessions).

The two pet-peeves are:

avoid abbreviations as those are context sensitive; given software development already mixes technical context (it’s software development!) and domain/semantic context it makes it extra hard to decipher abbreviations
if you want/need to mix technology and semantics in names (most often you do), start with the most meaningful semantics and end with the least meaningful technology
- if you don’t need technology in your names, at least put the most meaningful semantics and end with the least meaningful technology

Both very well amend what Felienne – a university professor – states in her research backed video:

“Their results show that ‘linguistic code smells’ actually increase cognitive loads,” she said. “Your brain has to work harder to process code that has these type of code smells. So that’s not what we want.”

I saved the [Wayback/Archive] tweets in the [Wayback/Archive] ThreadReader as this text (slightly edited for formatting):

Some notes on synching Google Drive data that other accounts shared with you

Posted by jpluimers on 2024/05/17

In the past (pre-2020) syncing shared Google Drive content was easy: Google Backup & Sync was still there and the web-UI of Google Drive was straightforward.

Syncing is important for me as it allows off-line working. Not all places have 24/7 internet access and not all cloud services are up 24/7.

So in 2020, with the mandatory (and often failing!) migration of Google Backup and Sync to Google Drive File Syncing and the new web-UI, things became a lot harder: Workaround to add a Shared With Me folder to your Google Drive (Google made this a lot harder in 2020).

Further into 2022 I discovered that way had become impossible for:

new shares
old shares that you had not set up syncing for

Old shares that you had set up syncing for kept working, and I hope they will for a long time, but I doubt they will.

Note this is not about free vs paid Google Drive data: the new situation fails for both cases.

For new shares or old shares you have not set up syncing for there basically seem to be two solutions, neither of them which is nice:

How NOT to Measure Latency

Posted by jpluimers on 2024/05/15

According to @isotopp (Kristian Köhntopp ), this is one of the most important talks to watch regarding performance issues: [Wayback/Archive.is] How NOT to Measure Latency

Gil Tene provides an in-depth overview of Latency and Response Time Characterization, including proven methodologies for measuring, reporting, and investigating latencies, and overview of some common pitfalls encountered (far too often) in the field. Tene also covers specific considerations in garbage collected environments (such as Java).

It is on YouTube (embedded below the signature) as well, but the above link as synchronised slides plus video.

More places where you can get it:

Via [Archive.is] Kristian Köhntopp on Twitter: “… Dieser Talk ist einer der wichtigsten Talks überhaupt, wenn es um das debuggen von “Performance Problemen” oder SLOs geht.”
