  • I’m a mech E in the medical field. We’re consistently understaffed. If I validate an Excel worksheet in Excel '08 or a Python program in 3.5 with a specific version of NumPy, we’re probably sticking with those versions for a while. Every time I bring up re-validating with the latest version, keeping one old system running the old software requires fewer resources than me or a colleague re-validating.

    My whole department is stuck on one version of Python because that was the most recent version when I had an emergency project and developed a data analysis algorithm. We validated it, then as new members were added to my team, they needed a copy, so we had to keep using it. I’ll probably re-validate it to the next Python release. It’s not only unit tests, or we could automate validation. Unit tests are a tiny part of validating software for making medical decisions. And software that directly runs a medical device (like firmware on an insulin pump) is an order of magnitude more rigorous than what I do.

    Side note: there are people who somehow root their insulin pumps and run algorithms on them. There’s a group that can get a PID control loop on an insulin pump that has a more simple control scheme on it (because that’s how the FDA approved it). The company has been trying to get approval to use PID control in the US for years.


  • Seriously? I was looking at a Surface product recently, and it appeared to have an access panel for the NVME drive. I read a ton of complaints about the dimensions of the drive being unusual, but access to it was easy. I don’t think I was looking at a Surface pro though.

    If a surface pro wants to be a full OS and not a tablet OS, it should be easy to replace the storage device.

    I haven’t dealt with HPC in a while, but Intel C compiler against MKL libraries were fastest CPU, and Nvidia CUDA was slightly easier to develop than OpenCL for other cards. I’m not sure if the situation’s changed.

    For my current applications, I use NumPy compiled against Intel MKV installed as a binary. It works great.





  • Technically second distro I ever installed, but the first one I actually used. I purchased Mandrake when it was based on RedHat, but didn’t get very far with it. In college I inherited always on Internet in my dorm and ran a Slackware webserver, and later fileserver and BitTorrent machine. I tried running Slackware on my laptop but I couldn’t get the battery management to work, but I dual booted for a couple of years.
