Ask HN: How to navigate USB-C charging hell
4 by kuon | 3 comments on Hacker News.
I realize this topic has been discussed numerous times, but after some research I found about 50 different "theories" on how it is supposed to work. As a developer and electronic engineer, it deeply frustrate me to have no good understanding of it. I am quite sure that the actual protocol and electrical details are simple, but because everybody comes with their own theory, navigating google results is really hard. Long story short, I built a new threadripper workstation, and none of the gazillion of USB port will charge my One Plus 5T phone. I tried all the the A-C ports with different cables (aren't A port just 4 contacts? what can be in the cable, resistors?...). I also tried C-C and it doesn't charge either. So, two questions: - Is there a good, technically precise and right explanation of the whole situation? I tried reading the USB standard, but it would take days to extract a proper understanding of it. - In there an adapter or something I can use on USB-C port of my workstation to provide a "charge port" for my phone which seems to require some voodoo magic to charge? I am posting on HN because it has a lot of visibility, and I hope this post might become a beacon of hope in the USB situation (this part is very pretentious, but HN did surprise me quite many times).

New ask Hacker News story: Tell HN: Equifax free credit report dark patterns

Tell HN: Equifax free credit report dark patterns 4 by PopAlongKid | 0 comments on Hacker News. For years, I have been obtaining free annual credit reports (annualcreditreport.com) which must be provided by law. Recently, for the first time, when I tried to obtain my Equifax report, I was prompted for an email address and a mobile phone number, a new requirement that apparently cannot be bypassed. The other two bureaus, and Equifax previously, confirmed identity by asking knowledge based questions. They do not need my phone or email for anything. Next, trying to obtain the report by phone instead of web site per instructions, I got to the point where I entered my ZIP code on the phone keypad, the voice menu system correctly repeated the number back to me, but every time I press 1 to indicate it is correct, the system acts like it got an invalid response and only gives me the option to enter further information by voice, not by the phone keypad. Just as with my phone number and email

New ask Hacker News story: Ask HN: Why can't the US government run their own social media?

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
