  • 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.


  • The business strategy decisions behind CPU fab is really interesting over the past 15 years.

    AMD made a budget clone of Intel two decades ago. Then Intel made a misstep and released Northwood Pentium 4. AMD used less power and was faster. And AMD decided to go with DDR memory, while Intel went RDRAM. Then AMD was king when they went AMDx86-64 for 64 bit and Intel went Itanium.

    Then AMD made a huge miscalculation on the future of multicore computing and designed Bulldozer, while Intel got their shit together and went down the hyperthreading route and released CORE/Core2/Core2Duo chips. And Intel was king for a decade.

    I don’t know the exact timing, but AMD needed cash and sold their fabs to raise money, which became TSMC GlobalFoundries, sorry. GF learned how to make stuff small since smartphones became a huge market. Then AMD let an engineer run the company and she invested in the Zen architecture, which could be made by GF with their lessons from the mobile world.

    This is my take. By AMD turning GF loose, GF could date other people work on mobile projects, which helped them learn.

    It’s a side note now, but Intel hung on to their fabs and lagged behind GF. AMD let their fab go and benefitted from it. EDIT: I had some facts wrong. It’s possible Intel fabs are ahead of GF.

    As a side note, Intel did try fairly hard to get into mobile like GF. They had the Atom chips and went for tablet, Ultrabook, netbook, and mobile. I had an ASUS Android phone with an Intel SOC. So it’s not like they ignored mobile, but it didn’t benefit them as much as TSMC.


  • There are methodical ways of valuating a private (and public) company. Some are pessimistic and some are wildly optimistic. Your can legally use whichever one you want, only you must only use that valuation method for everything. It’s illegal to value the company low for taxes and high for loan collateral. And if you sell it, you can owe back taxes if your valuation was off (sale price is the new valuation).

    This is overly-simplified US accounting rules (from finance class 10 years ago)





  • Yeah. I know people who say stuff like that. I know someone who wanted a convertible car (they were 18). Someone mentioned the greater danger of they flip, and this person said “well I’m not going to flip a car”. We all gave them a hard time about whether they thought everyone who flipped a car did it on purpose. The next year, this same person flipped their car several times (and walked away OK somehow).

    Some people can’t comprehend that bad stuff would happen to them.



  • I’m not following closely and haven’t gamed on PC in a while but:

    Denovo is a technology that is supposed to prevent copying games (DRM). Not sure what it’s current state is or might be mixing it up with other DRM, but DRM is known for causing headaches for paying customers. Using excessive system resources, refusal to launch for legitimate paying customers, spyware/excessive data collected and sent to a corporation, etc. In some games, volunteers will patch bugs out of a game, and this will cause the game to think it’s cracked and refuse to launch.

    Some DRM is “phone home” and can’t be played offline, so people in remote areas can’t play. And sometimes the company doesn’t want to keep servers online when the game has been out for 10 years, so people that purchased the game can no longer play.

    In this case, the company let reviewers rate the game and got the initial scores and sales, then pushed the unpopular DRM update. It’s scummy. If you’re using it, then use it. Don’t bait and switch.


  • Almost a decade ago that was true. I use budget Android phones, and Brave was the only ad-blocking browser I could use. Firefox with ad-blocking plugins was slower than Chrome with ads. Brave was chromium based and was by far the most responsive way to browse the web.

    Firefox got their act together and now the Android version is great. And the plugins work well. Brave began substituting some site ads for their own ads, if I remember correctly. You’d see fewer ads, but Brave was getting some money to let a few through.
