Electronic Ink such as that found on Amazon Kindle is the greatest invention ever made by man.
Once E Ink reaches reasonable refresh rates to replace liquid crystal displays, the world will finally be saved.
It would allow Ciro Santilli to spend his entire life in front of a screen rather in the real world without getting tired eyes, and even if it is sunny outside.
Ciro stopped reading non-code non-news a while back though, so the current refresh rates are useless, what a shame.
OMG, this is amazing: getfreewrite.com/

Holy fuck the type of data source that we get in this area of work!
This pastebin contained a few new hits, in addition to some pre-existing ones. Most of the hits them seem to be linked to the IP 72.34.53.174, which presumably is a major part of the fingerprint found by CYBERTAZIEX, though unsurprisingly methodology is unclear. As documented, the domains appear to be linked to a "Condor hosting" provider, but it is hard to find any information about it online.
Ciro Santilli checked every single non-subdomain domain in the list.
Other files under the same account: pastebin.com/u/cybertaziex did not seem of interest.
The author's real name appears to be Deni Suwandi: twitter.com/denz_999 from Indonesia, but all accounts appear to be inactive, otherwise we'd ping him to ask for more info about the list.
Organelle that is only present in prokaryotes.
en.wikipedia.org/wiki/Logarithm_of_a_matrix#Existence mentions it always exists for all invertible complex matrices. But the real condition is more complicated. Notable counter example: -1 cannot be reached by any real .
The Lie algebra exponential covering problem can be seen as a generalized version of this problem, because
- Lie algebra of is just the entire
- we can immediately exclude non-invertible matrices from being the result of the exponential, because has inverse , so we already know that non-invertible matrices are not reachable

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!
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.

- 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
