How to survive cancer: an inspiring story by Désirée Hairwassers

Posted by jpluimers on 2022/04/29

Today is my birthday. I am turning 53 today. But when writing this I’m not sure I am what we Dutch call “schoon”. It is a Dutch euphemism that I dislike, but still accidentally use. The thing is that one never knows for sure to be really clean from he signs of cancer metastases.

While writing this post, I’m in a melancholic mood during a period of depression/burnout after all the treatments. I am reflecting on if and how I survived the metastasised rectum cancer and lived through all other stressful things that started somewhere early 2017.

So I was glad to find the tweet below on the edge of spring that inspired me, I originally made me draft this post as being titled

“Surviving cancer is not a fight or a battle, it is about having luck or misfortune”

It was a (now by posting this link) pointer back to Having cancer is not a fight or a battle, it is about having luck or misfortune.

But it doesn’t do the artwork of Désirée Hairwassers justice, so here is her tweet:

[Wayback/Archive] Dees on Twitter: “Het lijkt mij ook een gepast moment om jullie mijn boek te presenteren. In het Engels, want gericht op de hele wereld. Dun boek. Dat moet een bestseller worden….. ” / Twitter

Translated: “I also think it is an appropriate time to present my book to you. In English, because aimed at the whole world. Thin book. That should be a bestseller”

And her video about “How to survive cancer: The inspirational journey of Désirée Hairwassers” showing the book. A very focused book (if it does not show, click on her above tweet to see it):

virtualization – Convert a hard-drive into a VMWare machine – Server Fault

Posted by jpluimers on 2022/04/29

Sometimes machines die without one having had the chance of doing a proper bootable file-system backup instead of a file-by-file-backup.

You can still P2V these machines (convert them from physical to virtual), but it is a lot more pain as you have to try to grab any installation keys for them and create a compatible virtual machine configuration by hand like I did in P2V of an existing XP machine to Hyper-V to have an emergency fallback when retiring old XP physical machines.

The below linked answer (with steps) uses Symantec Backup Exec System Recovery (now back in the hands of Veritas again as Backup Exec) to make part of this process towards VMware ESXi less tedious: [Wayback] virtualization – Convert a hard-drive into a VMWare machine – Server Fault (thanks [Wayback] Mark Booth and [Wayback] Dave M)

Doing this might require you to find old Windows XP media. Those are in the Internet Archive (often slower, but has the file hashes too) and The Eye (much faster from where I live in Europe); Internet Archive examples are for English, though other languages are present as well:

Got the Internet Archive tip from [Wayback/Archive.is] Where can I download an official Windows XP ISO? I have a license key if that helps? : windows, found the correct filename there, then downloaded the [Wayback] The Eye.

Setting up a GitHub project so it is served over https as a github.io and a custom subdomain

Posted by jpluimers on 2022/04/27

Some links that helped me getting this working:

The goal is to have a githubstatus.wiert.me plain html (or maybe markdown) page that eventually will show some status information (kind of like githubstatus.com, but for different things).

Note that for free accounts, private repositories cannot publish pages: [Wayback] Troubleshooting custom domains and GitHub Pages – GitHub Docs:

GitHub Pages is available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server. For more information, see “GitHub’s products.”

[Wayback] GitHub’s products contradicts this by limiting GitHub Pages to only GitHub Pro and GitHub Team and higher levels.

Steps I did

Since there are quite a few links above, here are the steps I took from my github.com/jpluimers account:

  1. For  jpluimers.github.io/jpluimers (steps 1, 3, 4 and 5 were the key ones):
    1. Created a new GitHub repository github.com/jpluimers/jpluimers with license (in my case MIT license) and README.md (which by default is filled like this).
    2. Amended the README.md from my StackExchange profile.
    3. Enabled Pages publishing by switching the source from None to the main branch.
    4. GitHub automagically published it at jpluimers.github.io/jpluimers.
    5. Verified it was running at jpluimers.github.io/jpluimers (note there is no site at jpluimers.github.io yet – it shows a 404 error as in this archived version, see below why).
    6. Fixed the Twitter profile link so it is easier to find back my surviving rectal cancer story.
    7. Fixed the link to my www.race-checker.com running results as by now that is a Chinese Porn site because the underlying company 4Athletes Sports GmbH went belly up in 2019 (and still owns the race-checker trademark) and  updated the half marathon results as well.
    8. I verified the deployment actions at github.com/jpluimers/jpluimers/deployments/activity_log?environment=github-pages.
  2. For jpluimers.github.io (step 1 and 3 were the key ones):
    1. Created a new GitHub repository github.com/jpluimers/jpluimers.github.io with license (in my case MIT license) and README.md (which by default is filled like this: only one heading 1 line with the name of the repository).
    2. GitHub automagically set the source to the main branch, then published it at jpluimers.github.io.
    3. Verified it was running at jpluimers.github.io.
    4. I verified the deployment action at github.com/jpluimers/jpluimers.github.io/deployments/activity_log?environment=github-pages.
  3. For githubstatus.wiert.me :
    1. Created a new GitHub repository github.com/jpluimers/jpluimers.github.io with license (in my case MIT license) and README.md (which by default is filled like this: only one heading 1 line with the name of the repository).
    2. Enabled Pages publishing by switching the source from None to the main branch.
    3. I verified the jpluimers.github.io/githubstatus.wiert.me page existed (it will be gone soon).
    4. Set the custom domain to githubstatus.wiert.me.
    5. Now GitHub, after the DNS check, complained rightly that “githubstatus.wiert.me is improperly configured”, as it needs to be “set up with a correct CNAME record … We recommend you change this to a CNAME record pointing to jpluimers.github.io.”.
    6. So in the DNS settings panel of my wiert.me domain, I added a DNS record of type CNAME, with name githubstatus.wiert.me pointing to jpluimers.github.io.
      CNAME githubstatus.wiert.me Alias of jpluimers.github.io

      CNAME githubstatus.wiert.me Alias of jpluimers.github.io

      1. In retrospect, I should have reversed steps 6. and 4, as now this was the order of events, with a lot of waiting for the DNS to time-out.

        The DNS timeout was because githubstatus.wiert.me originally pointed via the DNS CNAME entry *.wiert.me to the blog at wiert.me, the timeouts were set by the domain provider (in this case WordPress.com), see the DNS nslookup information for *.wiert.me [Wayback/Archive.is].

        If I had set the DNS CNAME first, then the below list would have been much shorter.

        This was the order of events waiting for the DNS to timeout and the CNAME entry to take effect:

          1. Before entering the githubstatus.wiert.me custom domain “Your site is ready to be published at https://jpluimers.github.io/githubstatus.wiert.me/
          2. After entering the githubstatus.wiert.me custom domain:

            Your site is published at http://githubstatus.wiert.me/

            and a “Check Again” button preceded with:

            githubstatus.wiert.me is improperly configured
            Your site’s DNS settings are using a custom subdomain, githubstatus.wiert.me, that’s not set up with a correct CNAME record.

            We recommend you change this to a CNAME record pointing to
            jpluimers.github.io.

            and an “☐ Enforce HTTPS” checkbox followed by:

            Unavailable for your site because your domain is not properly configured to support HTTPS (githubstatus.wiert.me)

          3. After configuring the DNS information, and pressing the “Check Again” button the text briefly shows

            githubstatus.wiert.me DNS check is in progress.
            Please wait for the DNS check to complete.

            and an “☐ Enforce HTTPS” checkbox followed by:

            Unavailable for your site because your domain is not properly configured to support HTTPS (githubstatus.wiert.me)

          4. After a few minutes at the top of the page:

            Domain githubstatus.wiert,me is not eligible for HTTPS at this time.

            followed by the same “Check Again” button preceded with:

            githubstatus.wiert.me is improperly configured
            Your site’s DNS settings are using a custom subdomain, githubstatus.wiert.me, that’s not set up with a correct CNAME record.

            We recommend you change this to a CNAME record pointing to
            jpluimers.github.io.

          5. A few more minutes later:

            Requesting a certificate for githubstatus.wiert.me. It can take up to an hour to propagate.

            followed again by the above “Check Again” button.

          6. More than an hour later:

            Certificate already exists for githubstatus.wriert.me and is usable.

            followed again by the above “Check Again” button.

          7. The next morning, a green checkmark () had appeared behind the githubstatus.wiert.me custom domain and the text following the “☐ Enforce HTTPS” had by:

            HTTPS provides a layer of encryption that prevents others from snooping on or tampering with traffic to your site.

          8. Both these URLs now function correctly (so I can test a page both with and without TLS):

        The above order is typical for DNS timeouts on a distributed computing system like GitHub: some parts of the system are waiting for the DNS time out and therefore list failure, while some other parts already have had the updated DNS CNAME entry and therefore list success

    7. After waiting for the DNS timeout (this was a long wait, I probably should have reversed steps 6. and 4.), verified that https://githubstatus.wiert.me/ was loading fine.
    8. I verified the deployment actions at github.com/jpluimers/githubstatus.wiert.me/deployments/activity_log?environment=github-pages

Note: I saved the TLS information – including certificates here:

GitHub – bbbradsmith/flompy: DOS floppy disk dumper

Posted by jpluimers on 2022/04/26

Need one day when archiving old floppies: [WayBack] GitHub – bbbradsmith/flompy: DOS floppy disk dumper

Via: [WayBack] Brad Smith on Twitter: “So I wrote a floppy disk dumper program for DOS. I dunno if this is really a very useful thing, but it’s open-source at least! 💾⚡🖥 “

Full thread at [WayBack] Thread by @bbbradsmith: “Hrm… why doesn’t the floppy controller status register have its non-DMA bit set, even though I’ve used a specify command to set it… and […]”:
