Holy cow! 🐄 How hard could it be to sign a PDF on #Linux!? 🤨 FoxitReader hangs and OnlyOffice seems not having this feature. You can draw in the pdf viewer, but thats useless... I ended up borrowing an iPad with a pen to do the trick.

The ideas that I've found online are overcomplicated.

Do you have any hints what app to use? If only #Vivaldi would have such a feature!

I have two different signatures, one for digital and one for pen-and-paper… both stylized in my own way :-)

CBCDigital contracts are the norm today. Is there still power in a written signature? | CBC RadioThese days, it's far more common for most of us to sign our names on a touch screen, or to simply click a box on an online form, than to sign your name with a pen on paper.

Today, it's exactly one month since I released #swad 0.11. And I'm slowly closing in on releasing 0.12.

The change to a "multi #reactor" design was massive. It pays off though. On the hardware that could reach a throughput of roughly 1000 requests per second, I can now support over 3000 r/s, and when disabling #TLS, 10 times as much. Most of the time, I spent with "detective work" to find the causes for a variety of crashes, and now I'm quite confident I found them all, at least on #FreeBSD with default options. As 0.11 still has a bug affecting for example the #epoll backend on #Linux, expect to see swad 0.12 released very very soon.

I'm still not perfectly happy with RAM consumption (although that could also be improved by explicitly NOT releasing some objects and reusing them instead), and there are other things that could be improved in the future, e.g. experiment with how to distribute incoming connections to the worker threads, so there's not one "loser" that always gets slowed down massively by all the others. Or design and implement alternative #JWT #signature algorithms besides #HS256 which could enable horizontal scaling via load balancing. Etc. But I think the improvements for now are enough for a release. 😉

Что скрывается за EIP-712: подробный разбор стандарта

EIP-712 — это стандарт, который делает подписи в Ethereum не только безопасными, но и человекочитаемыми. Он позволяет кошелькам показывать пользователю, что скрывается под подписью, состоящей из набора байт. В этой статье разбираем, как устроен EIP-712: от домена и хеширования до тонкостей кодирования различных типов данных. Посмотрим, как правильно реализовать проверку подписи на смарт-контракте, какие ошибки чаще всего допускают солидити разработчики — ведь даже у OpenZeppelin находили баги.
