This is a good company, first they truly helped reduce international transfer fees. They they continued to morph into a decent challenger bank.
Brick and mortar banks were way way behind in that regard!
E.g. October 2023, Wise was doing 4.87% interest after fees, while Barclay's best option was 1.16% above 5k pounds on the Rainy Day Saver (5% below). Ridiculous!
CIA 2010 covert communication websites Expired domain trackers by 
Ciro Santilli 40 Updated 2025-07-16
Ciro Santilli 40 Updated 2025-07-16When you Google most of the hit domains, many of them show up on "expired domain trackers", and above all Chinese expired domain trackers for some reason, notably e.g.:This suggests that scraping these lists might be a good starting point to obtaining "all expired domains ever".
- hupo.com: e.g. static.hupo.com/expdomain_myadmin/2012-03-06（国际域名）.txt. Heavily IP throttled. Tor hindered more than helped.Scraping script: ../cia-2010-covert-communication-websites/hupo.sh. Scraping does about 1 day every 5 minutes relatively reliably, so about 36 hours / year. Not bad.Results are stored under
tmp/humo/<day>.Check for hit overlap:The hits are very well distributed amongst days and months, at least they did a good job hiding these potential timing fingerprints. This feels very deliberately designed.grep -Fx -f <( jq -r '.[].host' ../media/cia-2010-covert-communication-websites/hits.json ) cia-2010-covert-communication-websites/tmp/hupo/*There are lots of hits. The data set is very inclusive. Also we understand that it must have been obtains through means other than Web crawling, since it contains so many of the hits.Some of their files are simply missing however unfortunately, e.g. neither of the following exist:webmasterhome.cn did contain that one however: domain.webmasterhome.cn/com/2012-07-01.asp. Hmm. we might have better luck over there then?2018-11-19 is corrupt in a new and wonderful way, with a bunch of trailing zeros:ends in:wget -O hupo-2018-11-19 'http://static.hupo.com/expdomain_myadmin/2018-11-19%EF%BC%88%E5%9B%BD%E9%99%85%E5%9F%9F%E5%90%8D%EF%BC%89.txt hd hupo-2018-11-19000ffff0 74 75 64 69 65 73 2e 63 6f 6d 0d 0a 70 31 63 6f |tudies.com..p1co| 00100000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 0018a5e0 00 00 00 00 00 00 00 00 00 |.........|More generally, several files contain invalid domain names with non-ASCII characters, e.g. 2013-01-02 contains365<D3>л<FA><C2><CC>.com. Domain names can only contain ASCII charters: stackoverflow.com/questions/1133424/what-are-the-valid-characters-that-can-show-up-in-a-url-host Maybe we should get rid of any such lines as noise.Some files around 2011-09-06 start with an empty line. 2014-01-15 starts with about twenty empty lines. Oh and that last one also has some trash bytes the end<B7><B5><BB><D8>. Beauty. - webmasterhome.cn: e.g. domain.webmasterhome.cn/com/2012-03-06.asp. Appears to contain the exact same data as "static.hupo.com"Also has some randomly missing dates like hupo.com, though different missing ones from hupo, so they complement each other nicely.Some of the URLs are broken and don't inform that with HTTP status code, they just replace the results with some Chinese text 无法找到该页 (The requested page could not be found):Several URLs just return length 0 content, e.g.:It is not fully clear if this is a throttling mechanism, or if the data is just missing entirely.

Therefore, data from 2018 onwards does not contain webmasterhome.cn data.Starting from2013-05-10the format changes randomly. This also shows us that they just have all the HTML pages as static files on their server.

Data comparison:
- 2012-01-01Looking only at the
.com:The lists are quite similar however.- webmastercn has just about ten extra ones than justdropped, the rest is exactly the same
- justdropped has some extra and some missing from hupo

On the Relative Motion of the Earth and the Luminiferous Ether by Ciro Santilli 40 Updated 2026-08-21
Ciro Santilli 40 Updated 2026-08-21This paper is in the public domain and people have uploaded it e.g. to glorious Wikisource: en.wikisource.org/wiki/On_the_Relative_Motion_of_the_Earth_and_the_Luminiferous_Ether including its amazing illustrations.
So dominant that it is usualy called just "zip".
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
