Wish he'd do the same for boardview file formats. I've already reverse-engineered a few like xzz and teboview but for some reason he's now somewhat oblivious to it ( I suppose since he doesn't repair any more he's not "in the game" as such ).

Helping the less fortunate is a form of human decency.

The people of the United States are exceedingly generous in giving their money to charities, foreign and domestic. Americans sent almost 30 billion dollars abroad to foreign recipients in 2023. Americans pretty much have decency covered. But this isn't about decency. It's about responsibility.

I think it's more about diplomacy and soft power. If the US was instrumental in ensuring your survival, you're more likely to have a favorable view of the US when you're an adult and can affect your nation's policies.

Same goes for allowing foreign students to attend US universities.

Comment Re:Corporate Cards (Score 1) 54

Most airline reservation systems require a saved booking (PNR = Passenger Name Record) before they can issue a ticket. So, the booking class and seats are locked in before you can make a payment. Once that's done, they can't really change the price, and you can pick which card you use. So, I would suspect that they aren't trying to identify a corporate card as part of their segmentation strategy.

Submission + - Another large Black hole in "our" Galaxy (arxiv.org)

RockDoctor writes: A recent paper on ArXiv reports a novel idea about the central regions of "our" galaxy.

Remember the hoopla a few years ago about radio-astronomical observations producing an "image" of our central black hole — or rather, an image of the accretion disc around the black hole — long designated by astronomers as "Sagittarius A*" (or SGR-A*)? If you remember the image published then, one thing should be striking — it's not very symmetrical. If you think about viewing a spinning object, then you'd expect to see something with a "mirror" symmetry plane where we would see the rotation axis (if someone had marked it). If anything, that published image has three bright spots on a fainter ring. And the spots are not even approximately the same brightness.

This paper suggests that the image we see is the result of the light (radio waves) from SGR-A* being "lensed" by another black hole, near (but not quite on) the line of sight between SGR-A* and us. By various modelling approaches, they then refine this idea to a "best-fit" of a black hole with mass around 1000 times the Sun, orbiting between the distance of the closest-observed star to SGR-A* ("S2" — most imaginative name, ever!), and around 10 times that distance. That's far enough to make a strong interaction with "S2" unlikely within the lifetime of S2 before it's accretion onto SGR-A*.)

The region around SGR-A* is crowded. Within 25 parsecs (~80 light years, the distance to Regulus [in the constellation Leo] or Merak [in the Great Bear]) there is around 4 times more mass in several millions of "normal" stars than in the SGR-A* black hole. Finding a large (not "super massive") black hole in such a concentration of matter shouldn't surprise anyone.

This proposed black hole is larger than anything which has been detected by gravitational waves (yet) ; but not immensely larger — only a factor of 15 or so. (The authors also anticipate the "what about these big black holes spiralling together?" question : quote "and the amplitude of gravitational waves generated by the binary black holes is negligible.")

Being so close to SGR-A*, the proposed black hole is likely to be moving rapidly across our line of sight. At the distance of "S2" it's orbital period would be around 26 years (but the "new" black hole is probably further out than than that). Which might be an explanation for some of the variability and "flickering" reported for SGR-A* ever since it's discovery.

As always, more observations are needed. Which, for SGR-A* are frequently being taken, so improving (or ruling out) this explanation should happen fairly quickly. But it's a very interesting, and fun, idea.

Comment Is it really about education? (Score 2, Insightful) 110

About the only thing outpacing higher education costs is healthcare costs. I've been awarded a few degrees, I've worked with several universities as an outsider to sponsor research, and I've spent years on an advisory board. May I suggest a few problems that need to be fixed?
- Tenured professors that teach maybe one or two classes a year
- Layers of administration that don't teach or really add to the value
- Buillshit jobs in administration. My pet peeve is the graduate school troll who has to measure the headings in every thesis to make sure they're exactly centered

Anyone care to add to the list?

Comment Re:Airlines still use mainframes (Score 1) 118

Yes, CrowdStrike would have affected Windows machines running as front-end terminals for any airline that has that. It may also affect a lot of the operational systems that often run on Windows (flight planning & dispatch, gate planning, etc)
Southwest does not use TPF any more, they're hosted by Amadeus and they're completely off the mainframes these days. SWA's previous system was running TPF, it was originally based on a clone of Braniff's system years ago, but this system was shut down about 8-10 years ago. Amadeus runs reservations for 150+ airlines around the world.
For the other US majors - AA runs on Sabre's system, AFAIK the core is still TPF but they're working on migrating everything to Google's cloud. DL runs their own mainframe system and UA runs on SHARES, which is the TPF system that Continental used.

Comment Re:Still waiting for the boardviews.... (Score 4, Informative) 23

That's because the schematics are basically under heavy NDA. Designing a motherboard is basically impossible without heavy help from Intel or AMD and that is provided under NDA only.

That's why boardviews are so nice - they don't reveal *anything* about the actual PCB fabrication other than position of the parts and the logical connections between the parts (ie, which pins are on the same net); they are not *design* files, likewise schematics aren't truly revealing a lot either, certainly not enough that you could implement a clone for exactly the reasons you cite, there's simply too many other things such as firmware, routing and actual timing/impedence-control of the signals that go well beyond what can be deduced from the schematic and/or boardview alone.

If you look at common boardview files for things like Macbooks, all they contain is a long list of the following data tuple
{ position, side, part#, pin#, network name } ... yet having a boardview + schematic goes a long way towards making things actually repairable.

Comment Still waiting for the boardviews.... (Score 3, Interesting) 23

I had hoped that Framework would be a real change in the market but we're still locked out from really repairing those boards because there's no boardview access.

Sure, you can fix some things without the schematic and/or boardview ( they're two separate things btw ), but if you really want to be able to service machines that have been damaged you do need both in this day & age.

I've approached Framework a few times and it keeps ending up with a dead end when it comes to the boardview ( even through the conduit of Louis Rossmann to assist ). Basically, the whole repairability marketing tilt is little more than skin deep; they don't even have the rights to the designs to distribute the boardviews, of which I will point out are NOT the same as design files.
