8_hours_ago··on Former Tesla Firmware Engineer Discusses the System
Certification. Many commercial RTOS's are already certified to ASIL-C or ASIL-D, which requires extensive testing to verify that the system will work as designed and every code path is covered by tests. Products exist like Automotive Grade Linux, but you will have to go through the verification and certification process yourself which isn't quick or cheap. I'm not even sure it's possible to certify Linux to ASIL-D.

So yes, I'm sure that Linux can work. But it will be difficult to prove to auditors that it will always work.

8_hours_ago··on Former Tesla Firmware Engineer Discusses the System
Automotive ADAS systems generally require ASIL-D certification, which is much easier with an RTOS than Linux. I don't have much experience with real-time embedded Linux, but my understanding is that it is very difficult or impossible to certify to ASIL-D. Can someone correct me?

My jaw hit the floor the first time I heard this. Why Linux instead of an RTOS?? Apparently Tesla's autopilot also runs Linux, which seems like a huge accident waiting to happen (pun intended).

SpyFone can only be used with consent of the device owner. From the Terms of Use (https://spyfone.com/terms-of-use/):

"You will only install the SpyFone software on devices for which you are the owner, or on devices for which you have received consent from the owner of the device."

Their service cannot be used by domestic abusers, obviously. (sarcasm)

"[wood ladders] don't conduct electricity like aluminum or wet fiberglass ladders do."

"'Aluminum or fiberglass, when it gets too hot, it gets soft; it will actually fold over without any warning,' he said. 'Wood takes hours to fail completely -- enough time for a firefighter to see it burning and get off it.'"

"Once an aluminum or fiberglass ladder cracks, it usually has to be replaced. Wooden ones can always be repaired, he said."

8_hours_ago··on Hello, GitHub
My company is concerned about that as well. We don’t use any cloud storage from Microsoft or anyone else, and we self host Exchange and SharePoint servers.

That is a good point though, it’s becoming more and more inconvenient for a company to self host everything. Microsoft does stand to benefit from everyone becoming more accustomed to relying on 3rd party services in the cloud.

8_hours_ago··on Hello, GitHub
I assumed that Microsoft has security policies to ensure that all confidential information (e.g. non-open-source code and strategic discussions) is stored on infrastructure controlled by Microsoft.

The company I work at is very careful about keeping our intellectual property on our infrastructure, and I am surprised that a larger company like Microsoft doesn't have similar policies.

8_hours_ago··on Hello, GitHub
> Long before the acquisition, we've been hosting important stuff in private GitHub repositories. Including having strategic discussions in those private repositories.

Wow! I am very surprised by that. Is that an officially allowed policy? Or is it something that is "don't ask for permission, ask for forgiveness"?

Huh? Not that I see. Private repos require a paid plan.

People like to complain about professional politicians, but I haven't heard a good argument against them that outweighs their benefits. Wouldn't a professional politician be better than one who doesn't really know what's going on? Governing is hard. Getting results in our political system requires difficult compromises. Creating policy, understanding the consequences of policy, and evaluating differences between policies requires domain expertise. Wouldn't someone with more experience be better?

8_hours_ago··on Depressing and faintly terrifying days for the C standard [pdf]
Large and complex pieces of software, and operating systems in particular, tend to be tightly tied to their compilers. It is never easy and in some cases practically impossible to port to a different compiler. I expect that Microsoft has come to terms with the fact that Windows will only support being compiled by their compiler.

When a different toolchain introduces a new feature for finding bugs that would be useful for Windows, the Microsoft compiler team can add that functionality to their own tools instead of porting Windows. An advantage of this is that they can customize the feature for exactly their use case. Yes, this is the definition of NIH syndrome, but that’s how large companies work.

8_hours_ago··on Depressing and faintly terrifying days for the C standard [pdf]
Presumably the compiler team wrote a test for that behavior so there won’t be a regression. I assume that Windows isn’t planning on switching compilers, so they can rely on that behavior as long as the Microsoft compiler passes all its tests.

8_hours_ago··on LocationSmart Leaked Location Data for All Major U.S. Carriers in Real Time

That is what I am looking for! Do you know where to find those providers?

8_hours_ago··on LocationSmart Leaked Location Data for All Major U.S. Carriers in Real Time
This is what I sent... feel free to mention any issues you see with it which may help other people.

Hello XX,

I am concerned about the security of my cell phone location information.

Yesterday, a vulnerability was found that leaked the real-time location of 95% of the cell phones in the US. That is unacceptable.

US cell phone carriers including AT&T, Sprint, T-Mobile and Verizon share personal information, including phone numbers and real-time location of cell phones, with companies such as LocationSmart, who then resells the information to other companies for marketing and other purposes. Carriers to not provide a way for users to opt-out of such sharing. This is completely legal under the current Electronic Communications Privacy Act. LocationSmart claims that they will not share the gathered information without user consent, but the definition of consent is vague, and that doesn't protect the public from security breaches. I understand that carriers need to have location data to comply with emergency 911 regulations, but it is unacceptable that they are able to share it with 3rd parties who may use it for dubious purposes, and may have lax security standards.

We need to have laws that protect the privacy of cell phone users, and do not allow carriers to sell personal information to 3rd parties. Or, and the very least, customers should be able to opt-out of such sharing from their carriers.

For more information on the vulnerability found yesterday, please see: https://krebsonsecurity.com/2018/05/tracking-firm-locationsm...

Please contact me if you have any questions.

Thank you, XX

I just wrote to my senators and representative in congress, and I urge everyone else to do the same. It is unacceptable that our personal information is so easily sold to 3rd parties by our cell phone carriers, with no way to opt-out.
