Plus, if my knowledge is properly up-to-date, no AMD processor supports those instructions, not even any member the recent and famously super efficient Ryzen family processors.

Windows is not written in C++, even if Microsoft did embrace C++ quite a bit with the infamous MFC and so on. Windows was originally written using C and assembly language, using the Pascal calling convention for efficiency. It was originall

It is not necessary to have a valid alternative to validly declare something as fundamentally flawed. ElasticSearch is as brittle as you can get. If you don't dimension Java heap sizes properly, nodes crash all the time and uncontrolla

The ray-scene hit test uses comparison between distances, which involves a square root for each sphere. If you switch to using squared distances, the comparison will work equally well and the code will be a lot faster in many cases. You wil

At my small startup we tried using Google Drive as a Dropbox replacement a year or two ago. We are paying for Google apps so it made sense to try they're Dropbox-like service, and it had some seeming advantages too. We found it to be a

I tried to use unison for serious production work a few years ago, and it fell short. It would fail or become incredibly slow with large (but not huge) amounts of data. A pity because the concept is great. I wonder if it has improved since.

I think that is reductionistic and misguided. I don't know the exact inside story of course, but this is how I read it, and how I honestly think this happened. They chose to have a garbage-collected, bytecode-VM-executed, OO language a

I seem to recall the USB bus on the RPi3 is limited to 480Mb/s, the fastest SD cards in the market are around 150MB/s, and the SDcard port on the RPi3 is below 25Mb/s.

I believe Raspberry Pi's SDCard port is limited to a bit below 25 MB/s, so that's gonna be the actual limit very often.

Is there a video of the talk? Would love to watch it. Congrats on the work, it looks great! I'm just missing more detail, since having just the slides is a bit on the dry side.

Indeed, and high DAUs doesn't translate to a high number of engaged users either. Just a 301 HTTP redirect through a domain as part of a chain can count as DAU and mean nothing.

I have no idea about this specific case, but this kind of claim can be very misleading, while remaining true. Maybe they used the tooling once for an offline script of some sort, and that is all.

The first version of C++ ever, designed by Bjarne Stroustrup at AT&T as a thin layer on top of C, was called "C with classes". It was implemented as some kind of source code preprocessor that took ".cc" code and outp

Are you implying that Sun had a larger impact than Microsoft? Of course "larger" is not well-defined if the dimension isn't specified, but in the financial context it is used, I would say that is a fair assessment.

My view of this is: all of us who have written a lot of code feel intuitively there is something wrong with how coding is done. It feels like we are repeating too much work every time, reinventing the wheel for the umpteenth time. It feels
