The key unlock was deleted in newer PLC software versions, but the lock logic remained.

After a certain update by NEWAG, the cabin controls would also display scary messages about copyright violations if the HMI detected a subset of conditions that should've engaged the
lock but the train was still operational.

The trains also had a GSM telemetry unit that was broadcasting lock conditions, and in some cases appeared to be able to lock the train remotely.

We found that the PLC code actually contained logic that would lock up the train with bogus error codes after some date, or if the train wasn't running for a given time. One version of the controller actually contained GPS coordinates to contain the behaviour to third party workshops.

It was also possible to unlock the trains by pressing a key combination in the cabin controls. None of this was documented.

I can finally reveal some research I've been involved with over the past year or so.

We (@redford, @mrtick and I) have reverse engineered the PLC code of NEWAG Impuls EMUs. These trains were locking up for arbitrary reasons after being serviced at third-party workshops. The manufacturer argued that this was because of malpractice by these workshops, and that they should be serviced by them instead of third parti
es.

this is my formal apology to the ministry of public health in lebanon, i did not mean to completely DOS your website when i did a basic surface level look at your website out of boredom

Google is trying to put the web in a cage in the same way they put your devices in a cage (Android, ChromeOS).

There’s one really easy, simple and efficient way to fight them: uninstall Chrome/Chromium, use #firefox

Do it. Now.

– But I prefer Chrome because of…

If you are not ready to sacrifice a little comfort (so little, Firefox is great) to save the web, then you don’t deserve a free web anyway. You are part of those killing it.

Remove Chrome. Install Firefox.

there is so much joy in me. there is so much life! and yet there is still so much potential joy to be found

cis feelings about cis privileges 

There is a power imbalance present whenever I'm engaging one-on-one with a cis person.

Let's use a real-life example to illustrate: An acquaintance since over a decade ago, who decided to befriend me when she realised I was trans, and who I have now blocked.

Like me, she's a native Swedish speaker and has white privilege, she's a woman, she has trauma and she's neurologically nonconforming. The difference is: She's cishet and I'm trans and queer.

Anyway, she was telling me about how I'm not a *trans* woman in her eyes, but just *a* woman like any other woman.

And I of course told her why that's not a nice thing to say.
