Download SharePoint Online built-in template?

I know that, with custom scripting enabled, you can save a SharePoint Online site as a template and then download the .wsp solution to your computer. I was wondering if this was possible with a built-in template, such as STS#0 or WIKI#0?

video – Is there any way to download only part of torrent movie?

I make little clips from series for English learners. It is from half to a minute long, but I have to download a whole episode to cut it.

Is there any way to download only part of the episode with torrent, for example, as soda player does during movie streaming?

Tried to dig around libtorrent, but didn’t find anything useful.
Thank you.

email – Can’t find Word doc I was working on within Outlook, but it was opened as an “eml” file after download from Gmail?

I was looking at an email in Gmail and wanted to open it up separately. I ended up clicking download, which downloaded an eml file and when I clicked on it, it opened in Outlook.

I opened the Word doc attached within the email and worked on it, while clicking save every 15 minutes or so.

Once I finished, I closed the doc after saving one last time, and then closed the email. However, the document is nowhere to be found on my computer.

Any chance at all that it is retrievable or did I just learn a lesson?

criptomoeda – Como posso fazer download de grande quantidade de dados da blockchain Ethereum?

Estou fazendo um trabalho acadêmico e preciso fazer download de grande quantidade de dados da blockchain do Ethereum. O serviço que mais se assemelha com o que quero é o da Etherscan, mas ela só permite fazer download de no máximo 5000 dados de transações de uma vez. Alguém sabe uma plataforma, mesmo que paga, que me permita fazer download de grande quantidade de dados? Ou até então, que tenha uma API. A API do coingecko e do coinmarketcap não me servem, pois não tem todas as criptomoedas.

malware – Where can i download a benign PE dataset? or at least which website is the best candidate for crawling and downloading normal executables?

I’m planning to gather a benign dataset for my ML malware detection model

the problem I’m having is finding benign PE files, i just need a source that has a dataset of normal executables, i will scan them with VT and extract benign ones, but i cant find anything useful

if there is nothing out there, then at least what is the best website that has the potential to be useful for a PE downloader crawler? (meaning its easy to crawl and automatically download .exe files without running into problems)

also another problem of using a download website is Installers, considering most of their files are installer and i need to install the program first, is there any good solution to this? is there any AutoIT script that somehow can install all types of installers ?

(I tried looking at surveys on using ML in malware detection like (1), but seems like non of the papers have released any useful benign dataset other than simple windows files which anyone can gather and is less than 10k, and very small amounts like 1000, i need to gather a large benign dataset, more than 50,000 benign files because my malware dataset is really large)
