    Quiet morning on the links, huh? I’ll chime in and say I appreciate the effort.

    Also, tangentially related to the first item

    The Air Force conducted a major test of the F-35 program when it conducted a deployment demonstration from Edwards Air Force Base in California to Mountain Home Air Force Base in Idaho in February and March 2016. This was the service’s first attempt to use an updated version of the ALIS?—?the ground-based computer system that is supposed to diagnose mechanical problems, order and track replacement parts, and guide maintenance crews through repairs.

    Whenever a squadron deploys, it must establish an ALIS hub wherever the F-35 is deployed. Crews set up an ALIS Standard Operating Unit (SOU), which consists of several cases of computer equipment. Technicians will use these to set up a small mainframe which must then be plugged into the world-wide ALIS network.

    It took several days for the crews to get ALIS working on the local base network. After extensive troubleshooting, IT personnel figured out they had to change several settings on Internet Explorer so ALIS users could log into the system. This included lowering security settings, which DOT&E noted with commendable understatement was “an action that may not be compatible with required cybersecurity and network protection standards.”

        This strikes me as being vaguely related to the age of the people in charge of advising the people in charge of approving the purchase order.

        The Colonels advising the Generals at this point know Linux as this crazy OS that only eggheads can use and we can’t expect Airmen Basic fresh out of boot to sit down at a computer and know how to use Linux but… yeah, they’re down with Windows.

        When we get Colonels who grew up in the post-Redhat era to start having enough stroke to be able to tell the General “New distros of Linux are different. They’re really user-friendly now”, we might be able to do a real and serious (and perhaps even cheap?) upgrade to military tech.

        (Sometimes I wonder how much money Microsoft lost due to Windows 8 when it comes to military contracts…)Report

                The F-16 was so badly unstable that, during its first high-speed taxi run, it oscillated so badly that it actually left the ground.

                It’s now being used as the Superior Legacy System We Never Should Have Stopped Buying in articles like the one by this turd, who’s gleefully reposting some forced-out general’s backstabbing of his former colleagues.

                ps the description: “”First, the roll control was too sensitive, too much roll rate as a function of stick force. Second, the exhaust nozzle control for the prototype was wired incorrectly. You had to be on the ground for the nozzle to be wide open, so as soon as you took the weight off the wheels, the nozzle closed and essentially doubled the thrust at idle.”

                So, um, the prototype for this Superior Legacy System was built so badly wrong that it was basically uncontrollable.Report

                Related: the success of the F-16 is largely due to avionics that (eventually) took care of all the fiddling details so quickly that the pilots had no idea it was happening.

                I imagine the first few prototypes were exciting birds, before that got that figured out.Report

      I figure that what happened was the people who wrote ALIS were mandated by the customer to use off-the-shelf software as a cost-savings measure.

      And, at the time, the off-the-shelf software was IE 8.

      The only backwards compatibility between IE 8 and IE 11 is the ability to parse basic HTML, so any hacks that made ALIS work on IE 8 are not available to IE 11…unless, as described, you turn all the security features off.

      And they’re not allowed to rewrite ALIS to work with IE 11 because “you already BOUGHT that software, we’re not gonna give you MORE MONEY to go BUY IT AGAIN”. And they’re not allowed to use an entirely different system because “off the shelf saves money, MAKE IT WORK.”Report

        This company I used to work at used a bug tracking system with an HTML front end that only worked on IE. Well, only on some versions of IE. Well, only on very specific patch levels of some versions of IE. Really, not “gotta have these patches”, but “gotta have these patches but not those, because those fix bugs it depends on”.

        Eventually, someone I worked with spent two days writing a dead simple HTML frontend that had no polish at all but worked on any browser without crashing or freezing.Report

    If you’re looking for tea leaves to read for 2018, here are some.

    I’m not totally sure how useful these are, given that only 31% of the folks in Colorado Springs voted and, especially, given that Tuesday was a huge snowstorm (a bunch of businesses closed, and my boss even sent out an email saying, paraphrased, “days like this are one of the reasons why we give you guys vacation days… stay safe, etc”).

    The takeaway is that people are now joking that Boulder has moved to Colorado Springs.

    A window into 2018? An outlier? What are your priors?Report

    Here’s an interesting idea.

    Right now, current wind turbines in offshore installations each have their own electrical generator mounted directly to the turbine (through a gearbox, obviously). The generated power then flows along cables to a central station where it is combined and conditioned for the grid.

    This idea removes the generator set from each turbine and replaces it with a seawater pump. The pumps move seawater under pressure to a central generating station and that is where it is turned into power. Hydraulic networks can balance out load variations easier than electrical systems can (or, perhaps, more cheaply, not sure).Report

                Eh, I’m iffy on whether he’ll get anything distinguishable from noise. Public taste for Middle Eastern adventurism is already really low (“bombing terrorists” is great, but people don’t want actual boots on the ground or any sign it’s going to become something serious that could turn into another slog like Iraq), low overall approval for Trump means skepticism as to the wisdom and effectiveness of any proposed plan is ‘baked into the cake’, and the fact that people seem pretty sick of Syria anyways.

                He might get a blip for doing something at all, maybe a larger one of Russia saber rattles back enough to push back on “So friendly with Russia” but….I suspect it’ll be down the memory hole by next weekend, and out of the polls.

                Just too much downward momentum for what is, in the end, just another bombing run in Syria. After several days of hemming and hawing. (And as Jaybird notes — nobody really wants to be involved in Syria anyways)Report

                Not sure who “those people” are in this sentence; thus far this is wildly popular with Trump-skeptical Twitter conservatives, which I would expect to be echoed among real people, and I assume the ever-present pro-action part of popular opinion will assert itself. He isn’t going to hit W post-9/11 numbers, but I wouldn’t be surprised if it at least got him over 50% approval.Report

                One difference is that I don’t Hillary woulda done what Trump just did: act unilaterally without either legal basis or political cover from allies. The end result, of course, isn’t any different but the politics is. The problem Trump now has is that he’s not only reversing course on his earlier isolationist policies, but he’s alienated so many allies who might have otherwise been willing to follow thru on this … well … pretty reflexive reaction to an event which previously wasn’t within the Trump-policy worldview.

      I suspect that, despite the lack of competence in either the WH or the State department, that the Russian’s are not overly concerned. Playing with chemical weapons draws undue attention, so letting Uncle Sam smack someone’s hands for doing it is perfectly fine by them.

      It reinforces who Assad’s friends are, doesn’t it? It also reminds Assad not to play with the big boy toys because that makes the world give a crap, if briefly, over Syria. Which is not so good for Russian interests.

      So I don’t suspect much beyond this. Trump lacks the popularity to get involved in Syria — the public appears in no mood for another Middle Eastern adventure. Russian interests weren’t significantly harmed (possibly even advanced) so I suspect this will be a return to the pre-chemical weapons status quo.Report
