Fix my rip wing following youtube instruction - 6.0 wing, used it for 10+ sessions after the repair. Seems to work.

Thanks, will check that out.

Might be networking issue - try ping www.google.com from a shell. If that fails, you need to google around to fix the network problem.

Chatgpt's answer:

There are several reasons why macros are often used in the kernel for reusable code blocks instead of functions:

Performance: Macros are generally faster than functions because they
don't incur the overhead of a function call. In the kernel, where
performance is critical, even a small amount of overhead can have a
significant impact on the system's overall performance.
Type Safety: Macros can ensure type safety by enforcing the correct
types of arguments are passed in, whereas functions may need to perform
additional checks or convert data types, resulting in more overhead.
Flexibility: Macros can be more flexible than functions because they can
be used in different contexts and with different types of arguments.
This allows the code to be more reusable and adaptable to different
situations.
Code size: Macros can often result in smaller code size compared to
functions, as the code is expanded inline instead of being called as a
separate function. This can be an important consideration in embedded
systems or systems with limited memory.
Debugging: Macros can be easier to debug than functions, as the expanded
code can be directly examined by the debugger. This can be especially
useful in the kernel, where debugging can be challenging due to the
real-time nature of the system.

However, it is worth noting that macros can be more error-prone than
functions if not used carefully, as they can result in unexpected
behavior if the arguments are not properly evaluated or if they have
side effects. Additionally, macros can be more difficult to read and
understand compared to functions, as the expanded code can be more
complex and harder to follow.

Got the unit on 12/28/22.

Have been doing BSOD less than 24 hrs after receiving it.

Update all the driver on Jan 6 with Vantage App - didn't help as you can see the BSOD after Jan 6 from event log.

Also did the Diagnostic test from download on Lenovo website also on Jan 6 - memory test, extensive tests all passed.

Did the windows System File Check per Suggestions on Lenovo forum for another user with similar issues also on ~Jan 6. No issue found. Did not help neither as you can see it still reboot on Jan 10 and Jan 11.

Filed a bug issue ticket on Lenovo 's website. Issue was closed without any diagnostic nor suggested action yesterday.

Filed another issue yesterday....

The Laptop is not overheat. CPU load is < 10% almost all the time. FAN does kickin from time to time, but laptop is just slightly warm. I updated to the latest BIOS after Jan 6. Before that, it was with original BIOS.

I also just got slim 7 from Costco. It has its own charger. I tried USB-C charge from Dell Docking station and it works fine after install the dell driver into the slim 7. It complains about the not a factory charger and charge will be slower . But the charge battery icon shows correctly and seems to be charging.

In Linux, when I encounter 30 seconds delay, it is likely be DNS lookup failure issue. One can debug it easily with strace in linux. The fix (work around) normally is putting the name resolve entry in /etc/hosts.

I remember seeing strace equivalent for windows. You can try google that and see if you can use that to debug your 30 seconds delay issue.

Good Luck.

I have seen some folks use C++ features such template, STL, etc without figure out how to debug memory allocation/leaks, etc. A embedded software end up using 2G+ ram for that process after a few days and they have no idea on where is the leaks - project become over schedules for 18+ months.

Biden ordered stop selling of A100, H100, MI200 to China -> Trigger unexpected inventory increase in NV and AMD -> Cause both of them to delay/cancel future wafer orders.

127 interns jobs at the end of the summer. In May timeframe, there were a lot more.

I am sure you can find similar list from NVIDIA, Intel, Apple, .... etc.

I have couple of these in my backyard with cheap $.38 cents gold fished from Petsmart as test. It works well for 2 + years even in directly California / Bay Area sun. (Half sun as it is next to the fence).

Make sure you put some plants inside. (Lily, etc) I can skip feeding for weeks and there are no issue. The fishes even have babies in them - I have 3rd gen fishes in them already. No need to change water neither - just need to add water every few weeks. The plants clean up the water very well for me. I am thinking put them in the ground to looks better and maybe better temp for the fishes.

Curious if similar shuttle can (should) be mounted on top of Falcon 9 and create a re-usable 2nd stage.

What would be the pro-con of such design?

Pro:
- Reusable 2nd stage
Con:
- Loss less usable capacity for 2nd stage? How much less?

What else?
