Matt Godbolt's talk on ray tracers, shows how effective that change can be. Think it was that talk anyway. https://www.youtube.com/watch?v=HG6c4Kwbv4I

With C in the embedded world it is very common to write entire applications that never only use static memory and the stack. Sometime programmers will allow dynamic memory during init only, other times not even then (I tend to favour the ne

It's very common that both historical artifacts and natural wonders have been consumed by reservoirs, I suspect it would be almost impossible to avoid this.

For the codebase I was working on today (in C). At first it was just } so filtered those out, then it was /* (no comment detail on that line) so again filter them. Then it was a bunch of #includes. Not surprising but not insightful at

FPGA's also have billions of transistors now, but adding more block memory means removing transistors from something else, such as LUT's, registers, DSP blocks etc. As always it is a tradeoff, and given many designs don't nee

Recently at work I developed a small suite tools (in a mixture of python and shell, running in WSL) that left my boss impressed when he saw me debugging a customers system (IOT). Then he started asking me to make them accessible to non prog

Different volcano, but back in the 50's the natural tephra damn on the crater lake of Mount Ruapehu (New Zealand) collapsed triggering a lahar, that ultimately took out the piers of rail bridge near Tangiwai minutes before a passenger

That is correct, if the first few records (a virtual block size sorta) (not sure how many off the top of my head) don't compress well, it assumes that the file is not compressible and just writes the data out skipping the compression s

That quote doesn't contradict what mkl said, towards the end of the article it does say this thou, "The cloak will be on display in the new museum developed in Perth, set to open in Spring 2024."

Can hot-code reloading coexist well with inlined functions?

It isn't required (in the strict sense) to keep the dedup table in memory, the problem is that performance is dire when it doesn't. It would be pretty similar to virtual memory thrashing, when the table is not fully in memory.

What happened to Germany (territory shrinkage and economic sanctions) after WW1 incidentally shows this story pretty well.

The drive can infer that the LBA hasn't been mapped, since it won't be present in the FTL, there is no need for the OS to inform the drive of this.

You could use some sort of disk quota system, to make the filesystem artificially smaller than it actually is (trim after applying this change). Or simply insure that you don't exceed 80% - 90% used space. It it is also worth noting th

The SSD maintains a translation table for all the virtual addresses exposed by the drive, that maps to the underlying flash physical addresses. Any physical address not in that table, is unallocated and the drive can use freely.

My old T420 couldn't sleep overnight in Windows 7 (something would trigger a resume), but would sleep fine under Linux and FreeBSD.

Not sure if this is more or less extreme option, but you could put the TV in a Faraday cage, or build a Faraday cage into your walls.

Directly no, but if you moved the data to a new dataset, with a command that preserves the timestamp that would work (rsync -a or zfs send/recv), which could be run from a cronjob. Compression settings are set at a per dataset level, s

From what I have heard, the amount of work needed in porting native encryption to the original FreeBSD port of ZFS was actually what led to this project.

I can think of an example in New Zealand where an old law (Sedition) was essentially ignored for several decades. A couple years after its first use in a modern setting (early 00's) it was repealed.
