2020-01-03 No longer amazon.com associate on The Virtual Bookcase 1 year ago
I received a message from amazon that The Virtual Bookcase no longer qualifies as an amazon.com associate. That was no big surprise as I haven't done a lot of maintenance on the site and haven't added a lot of content in the last years.

The only serious maintenance was for the migration to the new web server where php 7.0 is the standard version. I wish to some day migrate to perl but haven't found time yet.

So I removed all amazon affiliate links I could find. This also means I can't use the amazon.com API anymore.

2018-01-03 Fixing stuff in The Virtual Bookcase for PHP 7 3 years ago
After spending an evening fixing scripts on The Virtual Bookcase to make them run in PHP 7 and make them safer at the same time I came to the conclusion that I still don't like php.

My conclusion is that if I want to maintain sites I'd rather redo them in perl. I noticed any serious maintenance on the scripts of The Virtual Bookcase was 9 years ago (!). That was also when I had the habit of writing maintenance scripts in perl and web code in php. The upside is that a part of the page-generating code is already available in perl.

But a rewrite is a task for another day. For now the site works cleanly in PHP 7 (and 5) and I can go on to the next task for moving the homeserver.

2017-08-19 Moving virtualbookcase.com to https 3 years ago
I received a notification from the google webmaster program that chrome browser would start showing security warnings on http://www.virtualbookcase.com/ due to the search box there.

The simple solution: make the site correctly available via https and redirect to the https version. I found out I already started doing the first bit and therefore the conversion was easy. Now with encrypted connections: The Virtual Bookcase.

2015-03-27 Overly interested Amazon EC2 nodes 6 years ago
On Camp Wireless and The Virtual Bookcase I see the following pattern in the access logs:
2620:108:700f::36bc:aade - - [27/Mar/2015:13:27:11 +0100] "GET / HTTP/1.1" 302 298 "-" "curl/7.36.0"
2406:da00:ff00::36e2:d963 - - [27/Mar/2015:13:27:38 +0100] "GET / HTTP/1.1" 302 298 "-" "curl/7.36.0"
Constant requests, 2 or 3 per minute from Amazon EC2 IPv6 addresses just requesting the / using curl. Over the day I now see 1334 unique addresses with at most 5 requests from one url.

The same pattern as described in Stange stream of HTTP GET requests in apache logs, from amazon ec2 instances - Server Fault with no real answer to the why.

It's not a problematic amount of traffic, I'd just like to understand what is happenning!

2014-08-04 IPv6 visitor stats 2014 6 years ago
Time to count IPv6 visitor percentage to different websites again:

Interesting numbers. Results for The Virtual Bookcase and Camp Wireless are totally skewed thanks to some IPv6 bot constantly checking the site from constantly changing IPv6 addresses .. but without privacy extensions enabled.

Method: unique IPv6 addresses seen in the whole month / total unique addresses seen in the whole month.

After the updates to virtualbookcase.com last weekend I noticed one other area of serious bit rot: character set damage. The pages were still charset=US-ASCII and this went noticeably wrong in HTML For Dummies® by Ed Tittel and Steve James. But there are only a few places where I had to change that, and the databases are all UTF8 anyway.

Funny is how the amount of visitors is slowly growing since this weekend. A few improvements and a few new links from my homepage, and suddenly more visitors.

I got around to posting reviews for books I read recently: But I noticed quite some bit rot on The Virtual Bookcase. Some scripts needed updating before I could add a book or post a review. And the reviews queue had been filled with lots of spam.

Big surprise yesterday: UPS logistics is able to do a 'deliver to neighbour' on a residential address. Since we have nice neighbours in the street a package was delivered there and we found the note to pick it up. That is quite an improvement over having to go to some warehouse in a far away industrial area only reachable by car.

In the package: two Amazon Kindles. Yes, we're going e-book! The main reason is quite simple: on cycling holidays books are a serious part of the weight we drag along. Having the entire library as a lightweight (240 gram) e-reader is nicer.

One effect is that I think I want to add something with editions / versions of books to detail pages about books on virtualbookcase so it is visible when a book is available in a kindle version. This has already been on my mind for UK/US versions (which happened for books like Harry Potter and the Half-Blood Prince (UK version) / Harry Potter and the Half-Blood Prince (US version). Ideally, I'd like to link all versions of the same book so I can show all reviews together. And as an added bonus I could show availability of hardback / paperback / kindle versions at places like amazon. But that will take some serious programming time...

I recently re-read The Fugitive Game: Online with Kevin Mitnick and noticed I never wrote a review for it. So I fixed that omission. It's a great book to read as it reads as a big adventure. But it took me a while to write a good review.
