And here I am, just wishing that someone with the knowledge would make font ligatures that render -- and --- as en and em dashes, so I could use them more.
One of the minor but very welcome latest updates of Microsoft Windows was the addition of the capability to type Win+- to get an en-dash (–) and Shift+Win+- to get an em dash (—).
> The company will proceed slowly, says Sharon Rosenzweig-Lipson, chief scientific officer at the company, treating up to 12 people with a specific type of glaucoma, and then up to 6 people with another condition, called NAION, that causes acute optic nerve damage. The genes will be regulated by a genetic switch that turns them on only when participants take a certain antibiotic.
This would be huge for IoT. It'll obviously be abused to send "metrics" (a.k.a. private data to be sold) by companies, but still. I hope there's no limit on SIM cards.
This is nice, though I think the use of indices instead of stable identifiers might bite in complex models that undergo changes. I've been toying with the idea that you could specify a point (2D or 3D in some coordinate system, depending on context) and pick the face/edge/point closest to that as the identifier. The only other alternative I see is diffing old and new, and trying to match the outputs of each operation geometrically, but that would produce extra output that needs to be persisted...
E.g. when splitting a face in OnShape, I might have to redo a whole bunch of operations later because the identifiers change, but I'm often surprised how good it is at matching up faces after a single operation. Like modifying a sketch, then having to add the new face to an extrusion, but then it magically does the right thing for chamfers and drafts.
Yep, topological naming solving is a hard problem to solve. It took FreeCAD many years to get it to work correctly. That's why I went with indices for this version. You can also use filters like extrusion.endFaces(face().arc()) to get only arc edges.
When the user click on a region we insert a 2D point, then the extrude feature will find the nearest face.
I have experimented with adding this picking logic to selections too select().pick() which will probably be merged in future releases.
Stock prices are reflection of what speculators expect to happen. So the depleted munitions thanks to Ukraine and the drive to get some independence from an unreliable Trump regime makes this unsurprising.
Indeed. Tit for tat is well known to be an effective strategy. It's almost guaranteed to create one side that feels weaker than the other, while giving that party a way out.
They certainly have, but the general idea is to first use stealth jets to bomb defensive systems (including radar observability) to conquer the skies, and then you can fly around somewhat freely. While SAM technology has improved, so have America's observability and stealth bombing capabilities. It will be interesting to learn the context and sequence of events which led to an F-15 being shot down by enemy fire.
(In 1991, the United States relied on the F-117 Nighthawk to penetrate Baghdad and launch salvos against radar and SAM sites. Simultaneously, Tomahawk cruise missiles were fired against similar communication and defense sites. In this war with Iran, the F-35 and B-2 have been used for stealth missions).
Recall that the Serbs shot down a Nighthawk when they were in a similar situation to Iran. They kept some good AA missiles in reserve and used a system of spotters and just waited for an opportunity. Its likely that similar tactics were used by Iran.
Also recall that the Houthis, armed and trained by Iran, gave F35s some close calls over Yemen.
The story is actually quite interesting. The Serbs observed that a nighthawk would routinely fly the same route but their radar couldn’t lock on it unless the missile hatch were open, which they managed to elicit.
In short, it took 2 rare events to occur for it to happen.
This isn’t unexpected for anyone in the actual military: they’ve planned for this for decades. A couple of friends served in the previous war and they mentioned that this is what their training exercises were like: same enemy, same difficulty.
Most of the F15 upgrades have been against other aircraft. The F15 is primarily an air superiority fighter, it isn’t designed for attacks or defence against ground forces. The F15E is modified to attack ground targets, but ideally they would be targets without any air defences.
The F-15E Strike Eagle variant is definitely designed for attacks and defense against ground forces, but overall air defense is a probability game so it's not too surprising that it eventually happened
Yes, although it’s designed for interdiction, rather than primarily a ground attack aircraft, the difference being that it’s intended to be used against defenceless ground targets (like supply lines), not on the front lines.
