The size of Thinkpad series T*s - 14". I had T460s, T470s, T490s and currently using T480s. I picked the wrong CPU for T490s and it fried two keyboards: several keys on the right including enter and backspace stopped working after ~6 m

Not mentioned by others, http://atlantic.net starts at $5 a month. DigitalOcean has a similar offer with much better documentation. I run a couple of larger servers at DigitalOcean and am really satisfied with uptime, management

If you're looking for a cheaper alternative then https://clusterhat.com/ is worth taking a look. I have one sitting on my desk (4 Pi Zero nodes and Raspberry Pi 2 controller).

I work from home 1-3 days a week. I'm also father of 3 boys (2, 8, 10) and wife is working full-time. My only setup is my ThinkPad T450s. That's all. At some point in my carrier I used 4 monitors, specific low profile keyboards an

I developed and maintained CI scripts for large modular C++ application 10+ years ago. Someone added `rm -rf $(SOME_TEMP_DIR)/` to global Makefile that was run before building anything. My CI scripts did not set SOME_TEMP_DIR... Came t

I quickly looked at it and "don't use envelopes by default", "paginate using Link headers" contradict what http://jsonapi.org/ specification says. json:api might not be the best standard and there

I probably should have started by telling it was years ago when applications had to work on OSes other than Linux and BSD (AIX, HP-UX, Solaris). Today it's libev or Boost.Asio. > why not just use poll(2) instead? Because as I mentio

What you wrote about the design flaws of select is correct but a feed set with 10,000 sockets is just 1250 bytes or 157 longs and hardware is very good at sequential memory access. I agree it will be slower than kqueue or epoll for long-liv

I did some tests years ago and a single-threaded event loop was able to handle more than 10,000 short-lived connections per second sending and receiving ISO 8583 bitmaps (38,000 with 2 threads if I remember correctly). And the bottleneck w

I have some questions: Have you experienced malloc failing a lot? How do you test to ensure error handling code paths work as expected? Have you read 'notes' section of Linux malloc manpage? It says: By default, Linux follows a
