2020-07-23 Twitter pointing me right at the dark side of social media 6 months ago
I separated my amateur radio twitter from my work and other contacts twitter to get less depressing world politics in my timeline and today Twitter showed me very clearly that I'm supposed to get agitated and depressed and not retreat into a safer bubble.

I got notifications on the @PE4KH account (including on my phone) to look at this tweet by Phil Karn KA9Q: Fascism has arrived in America. which quotes another political tweet.

I really appreciate the work Phil Karn has done in the past for networking and amateur radio, and as a person I feel sorry for him and others to have to live their daily lives in a situation like this.

But at the same time I don't want to be reminded constantly, because I can't do much about it and I will just feel more depressed. So it really annoys me that Twitter goes out of its way to point me to something that will agitate and depress me.

It seems like Twitter wants more doomscrolling and more depression to increase "engagement" at the short term.

2020-07-02 My social media accounts 6 months ago
Social media is a nice and easy way to interact with people. There was and is a lot of choice in social media. Ages ago I started with fidonet echomail groups, later with usenet and recently with web-based social media.

But that's also a development from volunteer-run systems to commercially run systems. Companies like twitter, google and facebook are in the world to make a profit. With echomail and usenet the protocols and software were not linked to the operator of the service, someone else was able to run the same service and allow access to the network again. When google+ stopped the ties to people I knew were broken and I had to find them again on other networks.

I am somewhat active on twitter. My 'main' twitter account is twitter.com/khoos but I was getting a lot of negative messages about world politics which got depressing. Since twitter has made it a lot easier to manage more than one twitter account from the twitter web interface I decided to add a specific account for amateur radio with the predictable name twitter.com/PE4KH. Amateur radio twitter is not completely free of politics, but it's a lot more sane view of twitter.

2020-05-25 Websites get attacked from the very first moment 8 months ago
Cybercriminal Sometimes hobby and work intertwine when I'm not expecting it.

I set up a domainname and added a dummy website for something related to amateur radio. I have no idea if it will go anywhere, but I thought I'd get the web configuration right. The domain name isn't published anywhere.

But, to my surprise:
178.174.174.11 - - [20/May/2020:09:14:35 +0200] "GET /.git/HEAD HTTP/1.0" 404 594 "-" "-"
178.174.174.11 - - [20/May/2020:09:14:35 +0200] "GET /.git/HEAD HTTP/1.0" 404 594 "-" "-"
178.174.174.11 - - [20/May/2020:09:14:53 +0200] "GET /.git/HEAD HTTP/1.0" 404 594 "-" "-"
178.174.174.11 - - [20/May/2020:09:14:53 +0200] "GET /.git/HEAD HTTP/1.0" 404 594 "-" "-"
81.92.203.216 - - [20/May/2020:09:15:12 +0200] "GET /.git/HEAD HTTP/1.0" 404 594 "-" "-"
2a00:d680:30:50::67 - - [24/May/2020:16:54:36 +0200] "GET /wp-login.php HTTP/1.1" 404 594 "http://******.*******.**/wp-login.php" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0"
I added the domain name and requested a LetsEncrypt certificate on 11 May 2020, I set up the webserver correctly on 19 May 2020. The only 'publication' of the name is via the certificate transparancy log. Somehow this is enough for the first probes for possible security issues.

Looking in the haproxy logs finds even more requests on 15 and 18 May 2020. Part of the requests are via http, not https.

2020-05-12 Changing the CSS grid depending on screen size 8 months ago
Camp Wireless responsive design A special feature I realized when working with the CSS grids is that I can change the order in which objects are displayed based on screen width. Or whether they appear at all on small screens.

So now I'm working on stylesheets that change the grid to what works better on a mobile device. Which is what a lot of the visitors to Camp Wireless use!

On a small screen I want the important content to come first. There is not enough space for the extras at the top, and a mobile visitor wants fast answers to the question "where can I find a campsite".

2020-05-06 I discovered the CSS grid model 8 months ago
In my todo-list is a rewrite of Camp Wireless to stop maintaining PHP and make it more mobile-device friendly.

The reason to stop maintaining php is because I don't like it anymore which gives me a risk of having insecure code, which would be really bad for me. I'm rewriting it in Perl which isn't todays choice in web development either but it is what I can program good enough to avoid security errors.

The reason to make it more mobile-device friendly is that over half of the visitors to the site are using mobile devices. They want to find a campsite while travelling with a smartphone or other mobile device.

I was already using a media selector CSS, with variations for printer, I'm now looking at CSS grids which allows me to device the page into regions that move place depending on the available screensize. This makes separating content from page layout even easier.

2020-05-05 Internal documentation of my home network 8 months ago
A few times I had to lookup something again about the way things work in my setups. I made a remark before that I should set up a documentation wiki at home to keep this information somewhere central.

Right before I started with the homeserver conway I set up Mediawiki on a webserver. First on the previous homeserver greenblatt but as soon as web production was migrated to the new server I ran it on the web production server virtual machine.

So for a lot of 'how did I' questions there are answers, and some future plans. Also for plans on the house and on amateur radio related things.

People who know me from work will just say this is an extension of the trail of MediaWiki based documentation systems I left behind, and they are right.

2020-04-07 Troy Hunt: No I won't link to your spammy article 9 months ago
A recurring theme in rants here: link request spam written to look like a serious and personal request to improve an article on my site.

Troy Hunt seems to get a lot of those too, so he wrote No, I Won't Link to Your Spammy Article.

So we can now all stop doing stupid 'search engine optimization' and go back to sharing actual good content.

2020-01-17 Added the javascript IPv6 test 1 year ago
With very little javascript programming experience I managed to program a version of the IPv6 inline test that is what I wanted for a while: a simple IPv6 check in the right hand column of my homepage. With credit to the IPv6 test by Iljitsch van Beijnum. A needed test, because we really ran out of IPv4 addresses.

It took a lot of tries and debugging because I have absolutely zero javascript experience. But I learned slowly and managed to get what I want.

This is where I like having test environments. There were a lot of broken versions of the test on a separate minimal test page, then I implemented it on the developer version of my homepage and fixed the last errors in that combination and after that I committed the change to the versioning system and updated the production version which showed the update without problems in one go.

2019-10-20 Restored the webcam site and archives 1 year ago
I was looking at the overview of most requested but not available URLs and noticed there is still traffic to http://webcam.idefix.net/. For years that was the webcam site when I still had access to a reasonable location for putting up a webcam. First a good view at my previous house, and later a window with a good view from a server room at work.

So I dug up the archived images and scripts, cleaned them up and made them available again. There are no fresh images, just the aged archives.

2019-09-08 A thumbs up for robust scripts 1 year ago
Encrypt all the things meme Today some of the letsencrypt certificates were older than 60 days, so the renewal script started to kick in. Last year I completely automated the certificate renewal of letsencrypt certificates with dehydrated and wrote some scripts around the renewal process with hopefully enough error handling.

Today some of the error handling got tested, one renewal gave an error:
  + ERROR: An error occurred while sending post-request to https://acme-v02.api.letsencrypt.org/acme/new-order (Status 500)
And indeed the dehydrated script gave an error level, the resulting (empty!) .crt file wasn't copied and nothing happened. On the next run of the renewal script this certificate will still be older than 60 days and therefore the renewal will be tried again.
