For some reason the aligned memory allocator supplied by VS 2015 is really slow. See the following results: SSE::alignedMalloc is our implementation, which works in the standard way - it allocates requested size + alignment, then moves up the returned pointer to so that it is aligned, while storing the original pointer so it can be freed later. _mm_malloc is the VS function that returns aligned memory. It compiles to a call ..

As noted before , with systemd, your core dumps disappear into one of systemd’s log sinks, instead of being stored to the current directory. By now, they are recoverable by normal users again. TL;DR: Run coredumpctl gdb to invoke gdb with the most recent core dump. Related bug about disappearing coredumps: https://bugs.freedesktop.org/show_bug.cgi?id=54288 Scenario: A simple program that crashes with a segfault: ~/dumpcore$ cat dum....

It all started innocently enough. I had “jfrazelle” as my GitHub handle for years, but my Twitter, IRC and other handles are all “jessfraz”. No one on GitHub was actually using “jessfraz” so I sat on it waiting to make my move. I’m currently on vacation this week so of course I was looking to break all the things. One thing you must know about me is that at no point was I thinking I hate this. I actually love stuff like this, I live for....

My nephew Timofey has some trouble accepting the arbitrary authority of adults. In this case, while the mother was away, an older man said something to him in an authoritative voice. Timofey’s reaction was to try and search for his mother, and - after that proved ineffective - to discharge his emotions in a loud, angry but non-confrontational way. He just screamed some meaningless speech-like sounds into the air. Glossolalia - speaking ..

This is a bash function definition that takes you to the top level directory of a git project. function cdtop () { local git_root; git_root=`git rev-parse --show-toplevel`; if [ $? -eq 0 ] then cd ${git_root} else return 1 fi } Here's a git alias that does serves a similar purpose. What this does is define a new alias, exec, that executes a shell command in the current project's root. git config --global ali..

As of me typing these words, my little truck experiment has been going on for over a year and four months. That’s been more than enough time to see a thousand different questions fly through this site and my inbox, and every so often I’ll sit down and answer a few of them . But there’s one question that I haven’t answered, and can’t seem to escape. It’s usually one of the first questions to come up in conversation, and half a bazillion var..

I specifically attended yesterday’s Fuzenation Technology & Music Summit in Kitchener, Ontario to hear Steve Wozniak (a.k.a. The Woz) speak. In short, he’s the co-founder of Apple, and the engineer who created the Apple I and Apple II computers. The Apple II was the first successful, mass-produced personal computer, and as the Woz points out, the “first one that could play arcade games in full colour” (I still have an Apple II that I use..

If you are following Go development you probably know that: Go 1.7 moves the golang.org/x/net/context package into the standard library as context, Yeah ! Unfortunately it won’t work for everything, I’ve spent some time understanding this one. For example if you are using gRPC you can hit this problem, here is an interface generated by gRPC: type APRSServer interface { GetPastMessages(context.Context, *Point) (*ARPSMessages, error) } But wh..

Every year we hold an internal developers conference called DevCon. This year we had 295 submissions for talks, ranging from a deep technical dive into the inner workings of Kafka to a reflection on the power of office pranks. I wondered what, if anything, do these submissions have in common? Are there any common themes/topics being discussed? To find out I decided to visualize the talk submissions in a word cloud to create an easily under..

Go check out her blog, With High Probability. If I said “let’s talk about temperature and voltage”, you might be interested, but few would react the same if instead I suggested an umbrella term: harmonic functions. Harmonic functions are often introduced as foreign operators that ..

In one of my hobby projects I needed to display additional information on top of a running video. The whole project is based on the Raspberry Pi and Python. This article describes the approach I’ve taken to display arbitrary content over the video with the help of the very flexible (and admittedly awesome) Kivy framework.
