The problem with overcommitting beyond the sum of RAM and swap is that userspace processes can't protect themselves against the kernel's lies. You allocate memory, handle the result, access the address space and someone dies. The

You can still use ham packet radio protocols over ISM bands not held back by those stupid historical limitations and stay within the law.

Do you only offload aes-gcm or do the NICs handle chacha20-poly1305 too?

Waymo should be punished at least as harsh as a single driver honking away every night.

Much worse. If you can make the radio controlled servo to throw the chain during sprints this could cause a specific rider to crash.

Executives behind bars and multiple times the revenue from their illicit deals should work as incentive to guide the industry.

There is not just the big end of year congress, but also lots of smaller events organised and run by regional CCC (like) groups in Europe e.g. MRMCD, EasterHegg, the Dutch camps changing the name every time (next one is WHY2025).

The term implies the existence of a contract. By his own clear statements Dmitry did the firmware on his own as a volunteer because he liked the RP2350 and wanted to to contribute to the badge project.

Not the RP2040. That chip has no boot security from anyone with physical access to the QSPI or SWD pins.

> no hardware integer division The RP2040 SIO block contains one hardware divider per CPU core.

The funniest to watch was systemd deciding to kill user processes on "last logout" so it would happily kill your elected PostgreSQL cluster leader as soon as the last follower is done catching up the WAL via rsync (over SSH). It w

The first comes with a lot of trade-offs, but I would love to see two QSPI controllers or at least two chip select lines that can be controlled by an extra address bit. I also want the DMA engine to be able to address the SIO block to acces

Z-buffers don't just require about an other frame buffer worth of memory, but also lots of read and write bandwidth per pixel. This extra memory bandwidth requirement made them expensive to implement well. High end implementations used

SMT also allows the cores to hide memory latency by executing the other thread(s). Taken to the extreme end this would give you a barrel CPU.

I wish FreeBSD and Linux had Solaris style doors extended to support kqueue()/epoll() in addition to threads.

Files are normally stored hierarchically (e.g. atomically move directories), and updated in place. Objects are normally considered to exist in a flat namespace and are written/replaced atomically. Object storage requires less expensive

Are you claiming that SeaweedFS requires twice as much RAM as the sum of the sizes of the stored objects?

I just can't get over Cabo's choice to put 65 (yes 65) Bit fixed sized ints in the wire format and to top it off by making it ones complement (the sign bit is part of the type and the longest fixed sized ints are 64 bit range)...

I assume it's supposed to work by having the compiler track the lifetime of the inodes. The compiler is expected to help with ephemeral references (the file system still has to store the link count to disk).

So because an incumbent exists ESA should give up, let their production and development pipeline rot away and "enjoy" the monopoly until it's too late to change something?

Because the cost is a lot lower. Paying a few percent of overcapacity doesn’t change that.

It's almost as if you should understand security critical C code before you start patching it to death.

Because Russian "offerings" are lacking in comparison, but they don't have access to a lot of it.

One of most important technical details about resources in early MacOS is that it allowed the system to swap resources by using double indirect pointers (aka handles) with the lock bit stuffed into the upper 8 bits of the 32 bit. Stealing t

Users come to expect the performance that was never promised or even properly requested. Once you efficiently load the system they complain because you overdelivered and they got used to it.
