Calamityjanitor commented on ESP32 WiFi Superstitions   supakeen.com/weblog/esp32... · Posted by u/supakeen

I was having multiple ESP devices from different brands running totally different firmwares all drop out randomly when I switched to a new Asus wifi router.

Came across even more 'work arounds'; No spaces in the SSID, disable IPv6 for the whole network even if the ESP ignores it. Thing is all of these settings would reboot the router and reconnect everything, so it would seemingly work until the next dropout.

I found limiting them to 802.11g instead of connecting with 'n' stopped the dropouts for good. Even now I wouldn't say that is a cure-all and that any of these other recommendations don't work, I'd guess that each AP's firmware might have different conflicts with different devices.

What's the point of more bandwidth when virtually all carriers limit your data plans to 50 to 150 GB/month?
Calamityjanitor · 7 months ago
Here in Australia they'll charge more for 5G but limit it to 150mbps. That's slower than LTE's max, no wonder 5G uptake is slow.

Poor Grant in this article was always against the law but now has to talk as if it's a good idea.

I looked into who was pushing for this law; a personality on a Murdoch owned radio station, along with Murdoch's News corp, a TV advertising company owner, and Jonathan Haidt as mentioned in the article, who is an anti-woke anti-academia hack https://3quarksdaily.com/3quarksdaily/2024/07/why-academics-...

Feels weird and gross to me that legacy media / advertising companies are crying over kids's mental health when they've been targeting teenagers with impossible standards and negatively influencing their self image for decades.

My personal conspiracy theory is that it was done to avoid scrutiny of advertising practices. A few months before academics started publishing findings on how problematic social media ads are; unhealthy foods, gambling, alcohol, and just plain scams. https://www.admscentre.org.au/adobservatory/

With 'kids' removed from social media, advertisers can better get away with less savoury stuff.

The magic of password is that you can write them to paper or keep them in your mind. No interoperability issue if suddenly having to use it temporarily or permanently with another device, like if you lose your phone. And you can also pretend they don't exist and no one can prove otherwise. Also if you don't use a password manager, no one (hacker or else) can extract it from your head like it can be forced from your devices.

Realistically passwords can also be forced from your head using 'enhanced interrogation techniques'.

Are you sure they actually happened? as you say, at least one of us is confused. My understanding is that the added leap seconds never happened, they are just inserted to make the dates line up nicely. Perhaps this depends on the definition of second?
Calamityjanitor · 8 months ago
I'm honestly just diving into this now after reading the article, and not a total expert. Wikipedia has a table of a leap second happening across TAI (atomic clock that purely counts seconds) UTC, and unix timestamps according to POSIX: https://en.wikipedia.org/wiki/Unix_time#Leap_seconds

It works out to be that unix time spits out the same integer for 2 seconds.

> POSIX time, also known as Unix time, is the number of seconds since the Unix epoch, which was 1970-01-01 at 00:00:00. … I think there should be a concise explanation of the problem.

I don’t think that the definition that software engineers believe is wrong or misleading at all. It really is the number of seconds that have passed since Unix’s “beginning of time”.

But to address the problem the article brings up, here’s my attempt at a concise definition:

POSIX time, also known as Unix time, is the number of seconds since the Unix epoch, which was 1970-01-01 at 00:00:00, and does not include leap seconds that have been added periodically since the 1970s.

Calamityjanitor · 8 months ago
I think you're describing the exact confusion that developers have. Unix time doesn't include leap seconds, but they are real seconds that happened. Consider a system that counts days since 1970, but ignores leap years so doesn't count Feb 29. Those 29ths were actual days, just recorded strangely in the calendar. A system that ignores them is going to give you an inaccurate number of days since 1970.

This lede makes no sense:

> Remember when Apple blamed EU tech rules — and more specifically the Digital Markets Act — to justify the fact that Apple Intelligence wouldn’t be available in the European Union? Maybe that was just an attempt to turn EU users against their regulators as Apple Intelligence is coming to the EU in April 2025 along with local language support.

If they were NEVER bringing it to the EU, maybe I'd understand the cynicism. But that it's part of a phased roll-out where it just takes more time to come to the EU does not make it MORE likely that the cynics were correct. It's impossible to know for sure without some kind of Apple memo/emails, but I don't understand pointing to the new release date as proof of some ulterior motive.

I collect old laptops.

The difference in brightness and colour reproduction in a pair of 2003 PowerBooks, one used heavily and the other just stored…

It’s quite stark. Dim backlights and washed out colours.

Calamityjanitor · a year ago
Yeah just like OLED, the LED backlight on a LCD doesn't last. I just recently swapped out the backlight on my ~10 year old TV with a $30 new one off aliexpress. Way brighter again, and way less color accurate. At least it doesn't need to be ewaste now.

surely it won't hurt. at minimum, it makes the attacker's job much harder -- their window to exploit becomes max 30 seconds instead of however long you don't change your password.

Tools like evilnginx proxy the traffic, then grab the auth token / cookie after a successful login. From there you can send the session tokens to something like necrobrowser to automatically do whatever you want with the account. The whole hack can happen in seconds.

Hey, just going to say what I've been telling folks IRL, if you are reading this, and your parents and family members aren't tech savvy, you need to set them up with two factor authentication now.

Because you know how to do that, and it's so much easier than helping them when they get hacked.

Calamityjanitor · a year ago
MFA doesn't stop this kind of phishing. If you're tricked to put in your password, you'll likely put in your 2FA code right after. A yubi key or device passkey that uses webauthn can stop these methods, since the domain seeking authentication is checked and won't authenticate unless it's the original domain.

Even then, that won't help scams and fraud that just trick you into sending money, or direct you to install malware.
