I loved reading your comment and got curious: how he detected the bitflips?


It looks like computing math heavy process with known answer, like 301st prime, and comparing the result.

General memory testing programs like memtest86 or memtester sets random bits into memory and verify it.


Wait a second, JS in James Webb Space Telescope?? Doing what? I'd love to hear about its usecases in the telescope. Is there any blog post about it?


Which firewall software do you use? I should probably start using firewalls in my computers as well...


I've been using Fort: https://github.com/tnodir/fort

It's the best one I found after trying a few, because it's pretty easy to use, and lets me disable notification popups which is a part that always frustrates me about other options.


Why am I hearing about that specific FW in year 2026, this seems really good, at least the features written if it really supports rules based on parent processes, wildcards, SvcHost granularity without gotchas. Been wrangling with Windows FW for ages, trying to get some badly behaved programs to update like Discord, Teams and others that change install paths or updater executable names or hiddenly use msedgewebview2. PolicyAppId and tagging based rules have given some success but Windows FW is still really broken. Definitely giving Fort a try.


> A "Core Isolation: Memory Integrity" feature of Windows 10+ prevents creating such memory area (leading to BSOD).

> We tried to attestation sign the driver via new EV certificate by MS to fix the driver's limitation, but failed (see #108).

> So for now users have to disable the "Core Isolation: Memory Integrity" feature

Disabling HVCI doesn't sound like a good idea honestly. I mean they abuse kernel memory protection to bypass EV Certificate restrictions leaving the system in a state where another driver can mess with FW's internal structures using the same trick.


It's quite good! It definitely deserves to be more popular, I hope it gets some more recognition.

Wildcards are great, like you said for those apps that change the directory name every single update.


Thank you!!


It doesn't matter really because nowadays all of them are just a front-ends to Windows Firewall.

Also legitimate software (i.e. firewall/AV) cannot use "oldschool" tricks like system service descriptor table hooks to obtain godlike privileges these days, while malware sometimes can do this by exploiting vulnerabilities, so in such cases it may be an unequal fight.


Are you using a framework for developing with react native? I'd love to know if you have some blog posts on the UI part.

Thanks!


Thanks for a comment from outside of the bubble


I am going to start using this. Thank you!


First of all, thank you! What a treasure trove of data.

If I may ask a question, do you have historical air quality data?


You can access historical air quality data from August 2022 onwards: https://open-meteo.com/en/docs/air-quality-api#start_date=20.... Data is based on the Copernicus air quality forecast. All are references listed the documentation


Thank you!


If I may use your expertise a bit: I need air quality data for two cities, one of which doesn't have any air quality monitoring stations. Is there anything I can use as a proxy for air pollution, like satellite data? Also, do you know any sources for that data?

Thanks!

P.S.: I'm passionate about air quality, given I have alergies and was an active member of the bicycle activism movement for about 10 years.



Thank you!!


this is legit awesome!


This is awful in so many ways
