Не про ИБ, но про электрику, инженеров, вклад в историю, и наши ценности.

Недавний разговор со знакомым подтолкнул покопать вопрос - кто придумал УЗО (устройство защитного отключения - защищает вас от удара током практически в каждой современной квартире) и почему безопасным током утечки взяли порог в 30 мА?

Нарыл статью на вики - https://en.wikipedia.org/wiki/Charles_Dalziel

Чарльз Дэлзил изобрел УЗО в 1961 году, проводил эксперименты с током и людьми в Беркли, будучи профессором электротехники и компьютерных наук, был пионером в исследовании воздействия тока на людей и животных, написал книгу, десятки научных работ, по сути спас десятки тысяч жизней своим изобретением, и уже практически забыт - статья в вики почти пустая, не переведена на другие языки, упоминания есть только в специфической литературе.

В такое время живем, моргенштейна помним, инстасамку знаем, а инженеров и профессоров за полвека забываем.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.
