Kenapa kok sedih?
Besok sudah mulai kerja ya

Oh wow, TIL we can do:
```
static void *array[] = { &&foo, &&bar, &&hack };
goto *array[i];
```
Noted, thanks.
It seems the doc you referred is actually what I am looking for.
I will try to tweak the wake up sources and play around with those configurations. It is much better to have only the "power button" as a wake up source rather than having random unexpected wakeups.
I will test suspend-resume after tweaking it later today.
The watchdog reported CPU#6 stuck for 5946s (observed from the photo).
That is roughly 99 minutes bake, lol.
That means my laptop didn't just wake up right before I checked it.
It likely woke up and hit soft lockups almost immediately after I put it in my backpack and was running at full tilt for the entire journey from Sragen to Surakarta 
Shit.
Subject: "systemctl suspend" on Linux is not reliable.
How long has it been since last time I used the the emergency sync SysRq?
Today traveled to Surakarta for a family event, I departed from Sragen. I suspended my laptop with "systemctl suspend" and put it into my backpack.
When I arrived in Surakarta, I opened my bag and felt my bag was so hot. It turned out that my laptop was on (not in a sleep state) and everything was spinning at 100% CPU (especially firefox and vscode).
I had a chance to check htop and tried to kill firefox with "pkill -9 firefox", but then the system froze.
When the GUI froze, I could still see my caps lock button was still working indicated by the caps lock LED on-off still responed to my input.
I tried to jump to tty4 and tried to login, but then soft lockup warnings appeared, everything froze. I could not login from tty4 neither.
I invoked an emergency sync procedure (Alt+SysRq+s) and forced my laptop off. Unfortunately, the SysRq to print backtrace was disabled. I am not sure how to debug this.
I hope this was not a kernel bug, just hope it was a random bit flip in my RAM caused by an extrme temperature that led to this scary incident.
Hopefully, my persistent filesystem will still be ok, not corrupted.
A university textbook in Indonesia states that `char*` is the same as `char[]`

Mind-blowing.
Exploiting a 20-year-old bug in the Linux kernel to achieve full privilege escalation and container escape, plus a cool bug-hunting heuristic

Again, mati listrik lagi... Jam 02:42 pagi.
I doubt that it will be forward compatible, though.
BTW, using those bits to store extra user data can drastically simplify object identification.
I often use it when dealing with async I/O user data in epoll or io_uring.
How I typically macro this out to pack and unpack event bits:
```
#define EV_BIT_ALL (0xFFFFull << 48)
#define GET_EV_BIT(X) ((X) & EV_BIT_ALL)
#define CLEAR_EV_BIT(X) ((X) & ~EV_BIT_ALL)
#define SET_EV_BIT(X, EV) ((X) | ((uint64_t)(EV) << 48))
```

I really appreciate the elegance of pointer tagging. A standard 64-bit pointer isn't actually fully utilized for addressing. On most systems, virtual addresses are only 48 bits wide, leaving the upper 16 bits theoretically free to embed extra user data

Nice. Thanks for testing!

I plan to send this patch to upstream. Would you like to attach a Tested-by tag?
Kebayoran Lama, Jakarta Selatan baru saja mati listrik. Bersiaplah untuk kemungkinan terburuk.
Lmao, you just hit a kernel bug. Can you show the full call trace?
Netcup is good. I have been using netcup for almost 3 years and have no complaints.
Previously, Netcup only offers VPS located Germany and Austria regions. But recently, Netcup also offers Singapore region (which is good w.r.t. latency if you access it from Indonesia).
I recommend you to migrate to netcup.
> also how hard to register
Netcup will ask you to provide your selfie photo, ID, and your electricity bills.
While it was easy and quick for me to register, I have seen several GNU people were rejected. I am not sure what the reasons were behind the rejection.
