Ask HN: Do you use ETags for performance?
4 by willsmith72 | 1 comments on Hacker News.
I'm in the process of improving the performance of my app. Some stuff can be browser-cached, some stuff can be public-cached, but the data doesn't change much, and when it does I want the user to get the latest. At some point I'll probably have to setup programmatic cache-busting with a CDN. People don't talk about ETags nearly as much, and I know it's not the same performance gain as a cache, but are people using them in the wild?

Just as with my phone number and email...

Ask HN: Why can't the US government run their own social media? 2 by rglullis | 2 comments on Hacker News. With the news yesterday of POTUS joining threads.net and with the fanfare about the possibility of following him from other AP-compatible servers (like Mastodon), I was left wondering why is it that the White House couldn't just run their own services? Doesn't "POTUS is using threads for social media" feel a bit like "POTUS is using outlook.com for email"? Is there anything about the bureaucracy that stops their some small team to setup a Mastodon server on "social.whitehouse.gov" and make this a reality? I find it hard to believe that this would be "if it got hacked it could create diplomacy issues", because I don't think that Facebook is setting up any type of special infrastructure to deal with political figures on their platform. Also, none of this seems to be a problem for some of the EU governments. Maybe I am missin...
