Particularly tasteful is their choice of native speaker actors who speak their native language for less important narration, and English with an accent for more important moments, in particular when talking solo to the camera.

DIGITAL WEB RECOVERY - REVIEW OF THE BEST BITCOIN RECOVERY TEAM by Cynthia Joe 0 Updated 2025-04-18 +Created 2024-12-08
Cynthia Joe 0 Updated 2025-04-18 +Created 2024-12-08My journey into cryptocurrency was filled with excitement and hope. I had invested a significant amount in Ethereum (ETH), believing it would secure my financial future. But in a single, unfortunate moment, everything came crashing down. Due to a technical error and a lapse in security, I lost my entire investment. The amount of ETH I had worked so hard to accumulate, which once felt like the key to my financial freedom, was gone. I felt like I had lost not only my money but also my dreams and the future I had envisioned. The emotional toll was immense. I tried everything to recover my funds, from reaching out to various services to exploring online forums for solutions, but nothing seemed to work. The more I searched, the more hopeless I became. I was at a complete loss, unsure if I would ever be able to reclaim what was rightfully mine. That was when I discovered Digital Web Recovery. Initially, I was cautious, as I had heard of countless scams in the cryptocurrency recovery space. But after reading about their proven track record and the positive reviews from others who had been in similar situations, I decided to give them a try. I had nothing left to lose, and their expertise seemed like my last shot. I knew I had made the proper decision as soon as I got in touch with Digital Web Recovery. The group was considerate, professional, and understanding of my predicament. They told me they have the resources and expertise to assist me in getting my lost Ethereum back after attentively listening to my narrative and comprehending the specifics of my case. They gave me the certainty I needed, which gave me hope I hadn't had in weeks. The recovery process wasn’t instantaneous, but throughout the journey, I was kept informed at every stage. The team worked tirelessly, using their deep knowledge of the blockchain and cryptocurrency recovery techniques to track and retrieve my lost ETH. Website; digitalwebrecovery.com Email; digitalwebexperts@zohomail.com Their commitment was unmatched, and with every update, my optimism grew. Then, the day finally came when I received the news: my lost Ethereum had been recovered. It was hard to believe at first—I felt an overwhelming sense of relief and joy. I had gone from a place of complete despair to triumph, all thanks to the tireless efforts of the Digital Web Recovery team. The funds were returned, and with them, my peace of mind. This experience has been nothing short of transformative. Trusting Digital Web Recovery gave me back not only my investment but also my faith in the possibility of recovery. What seemed like a catastrophic loss was turned into a success story that I’ll never forget. If you're facing a similar situation, I cannot recommend Digital Web Recovery enough. They restored my lost funds and gave me a chance to move forward.

This one is good: stackoverflow.com/questions/36533429/generate-random-string-in-postgresql/44200391#44200391 as it also describes how to generate multiple values.
with symbols(characters) as (VALUES ('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'))
select string_agg(substr(characters, (random() * (length(characters) - 1) + 1)::INTEGER, 1), '')
from symbols
join generate_series(1,8) as word(chr_idx) on 1 = 1 -- word length
join generate_series(1,10000) as words(idx) on 1 = 1 -- # of words
group by idx;Then you can insert it into a row with:
create table tmp(s text);
insert into tmp(s)
select s from
(
with symbols(characters) as (VALUES ('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'))
select string_agg(substr(characters, (random() * (length(characters) - 1) + 1)::INTEGER, 1), '') as asdf
from symbols
join generate_series(1,8) as word(chr_idx) on 1 = 1 -- word length
join generate_series(1,10000) as words(idx) on 1 = 1 -- # of words
group by idx
) as sub(s);A more convenient approach is likely to define the function:
CREATE OR REPLACE FUNCTION random_string(int) RETURNS TEXT as $$
select
string_agg(substr(characters, (random() * length(characters) + 1)::integer, 1), '') as random_word
from (values('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 --')) as symbols(characters)
join generate_series(1, $1) on 1 = 1
$$ language sql;And then:
create table tmp(s text, t text);
insert into tmp(s) select random_string(10) from generate_series(10);- output one column per line: stackoverflow.com/questions/9604723/alternate-output-format-for-psql-showing-one-column-per-line-with-column-name

Convert project Gutenberg King James Bible to verse number to text dataset by Ciro Santilli 35 Updated 2025-04-18 +Created 2024-12-05
Ciro Santilli 35 Updated 2025-04-18 +Created 2024-12-05This section is about converting: www.gutenberg.org/ebooks/10, and most likely the plaintext version: stackoverflow.com/a/43060761/895245 to the same data format as www.kaggle.com/datasets/oswinrh/bible mapping book/chapter/verse to the text:
1 1 1 In the beginning God created the heaven and the earth.
1 1 2 And the earth was without form, and void; and darkness was upon the face of the deep.On particular annoyance is that the txt version has multiple verses per line at times.
Verse number to text:

It is obscene that the DVSA, which is the UK organ that officially setups up the theory driving tests, does not make all of its material open.
As such, it uses its monopoly on the test as an advantage to sell books and services that allow you to pass the tests.
Particularly obscene is their focus on an online service: www.safedrivingforlife.info/shop/official-dvsa-theory-test-kit-car-drivers-elearning (archive) a that you can only use for 30 days and costs 15 pounds as of 2024. This way you can't even buy the book used or go to a library.
Obscene.
Paying to take the test is fine. But paying for learning materials which help everyone become better drivers and saves lives? Obscene.

Ciro Santilli 35 Updated 2025-04-18 +Created 2024-12-04This one has a 3D model of C. elegans containing all the cells, browsable on the browser at: browser.openworm.org/.
Fantastic resouce that contains cross sections of C. elegans at various lengths of its body. Presumably frozen and cut with a Microtome and then scanned with electron microscopy.
Shame that there are so many parts missing.

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.
