Broken. This will generate page faults if your string ends at a page-boundry and start address isn't aligned on four bytes.

It's mostly about bandwidth depending on how the device is connected inside the computer (usb is much better than ps/2 or serial), polling frequency, and software filtering raw data properly (duplicates and such). Some improvement

Same here. I lost a disk to btrfs and did not manage to recover any data. No longer on my list of filesystems-I-trust. I guess Suse is the biggest contributor since the others stopped? It doesn't give me any confidence that it can be t

We stopped working on BeZilla when Mozilla decided to scrap all native gfx-backends and use Cairo.

No idea, but they have signed distance fields font rendering (phew) which you can enable to get proper font rendering: chrome://flags/#distance-field-text For some info: https://www.youtube.com/watch?v=CGZRHJv

For Go (as it is statically linked) you can use FROM SCRATCH. It's faster, smaller, easier. https://blog.docker.com/2016/09/docker-golang/

The minnowboard has GPIO connectors, and has already managed to boot Haiku in UEFI mode. A bit expensive though.

https://github.com/Lyndir/MasterPassword/ is probably a better idea as it has lots more features and supported platforms.

The first for-loop looks like it only stops if s* is zero or the pointer s is zero. Also you need to calculate size from the byte in the word that is zero, not the word itself.

I was thinking more how branch prediction is handled in the pipeline. Agner Fog states that on Haswell having branches in the same 16 byte block affects performance. Probably not enough to matter though.

Kind of similar to the one I wrote for Haiku: http://cgit.haiku-os.org/haiku/tree/src/system/libroot/posix... Makes me wonder if having testbyte() inside the loop will be good for branch prediction

I've been keeping an eye on malloc's for quite a while, and they are getting ridiculously big nowadays. The malloc complexity seems to be greater than the programs themselves. With that kind of complexity it's hard to do obj

DBCP seems to be a safe bet: http://wix.io/2013/06/12/how-many-threads-does-it-take-to-fi... But I think the new connection pool in Tomcat might be interesting as well.

Ah thanks for clearing that up. It's in a newer (C++03?) standard. I still have to deal with gcc 2.95 on a regular basis so I'm stuck in the old ways. I guess that is why the title was 'Modern C++'.

To me at least build_new_object example seems horribly wrong: If you allocate the object on the stack and then returns it, it will go out of scope with the function, and the memory overwritten with next stack usage. Or does modern C++ do so

I really really wish they'd Javadoc their code properly, before they do anything else at all..

It's not intended. It's clock and/or data-signals that leaks and has gotten amplified, if you look at it in an oscillator you will probably see a square or sawtooth wave at around 1KHz. You might even be able to read that dat
