100% agreed on all points. Evading the Phoenix on its terminal guidance near max range should be a viable strategy for avoiding it due to the bleed of kinetic energy. Though like the HARM (which an F-16 Wild Weasel pilot _hated_ due to the huge plume of smoke it creates; listen to https://www.youtube.com/watch?v=2EI2rYxMPHM), it should be launched at high altitude for the best probability of a kill at long range.
trevorishere··on Cobra Maneuver
Good point about the B-2. Does the Navy even perform Wild Weasel? That's usually the F-16's job and we can only "assume" that it was out of range of any USAF or collation airbase.

Of course, the country in question would have to be Iran due to the F-14... though the Felon hasn't been shipped outside (or inside of...heh) Russia.

And of course we come back to 'it's a movie' :-)

trevorishere··on Cobra Maneuver
Of course this is a hypothetical now that we've seen how "well kept" Russian equipment is, but the R-37M will technically reach out and touch American aircraft long before the AMRAAM is in range.

Gotta wait for the AIM-260.

Which do nothing for radar-guided SAMs... but pumping out chaff wouldn't be very visually impressive (if you could see it at all).

And of course, the strike package would have been accompanied by the EA-18G Growler to jam SAM radar.

War itself is terrible.

The machinery, ingenuity, and eventual incorporation of some of that technology into civilian life is important and possibly the only way to get funding for new technologies by the (US) government.

The NRO offered two spy satellites (I believe rumored to be Keyhole family satellites) to NASA back in 2011/2012 -- neither have launched yet, but they have the same sized mirror as the Hubble, but with a better focal length giving the satellites a 100 times wider field of view. The now-named Nancy Grace Roman Space Telescope is scheduled to launch by Nov 2026 on a Falcon Heavy.

The NRO also donated Keyhole satellite mirrors to create the Multiple Mirror Telescope.

https://en.wikipedia.org/wiki/MMT_Observatory#Multiple_Mirro...

NASA was the last to fly the SR-71 as a research platform.

Unfortunately, the military is often what pushes technology forward.

B-52 was the last USAF bomber to have a rear-ward facing guns. During the Gulf War, one of two theories that a rear-ward facing gunner turned on his defensive fire control system and was hit by friendly fire after an F4 released anti-radiation (HARM) missile in the blind. The AGM-88 locked on to the DFCS and blew off the rear section of the BUFF -- which was then nicknamed "In HARM's Way".

Last air-to-air cannon kill I'm aware of was an F-16 vs. OV-10 in Venezuela in 1992. You can watch the kill at https://www.youtube.com/watch?v=nDASW6X0XoU.

If you look closely at the moment of shoot down, you'll see the F-16 has its air breaks fully deployed (and I'd assume both leading and trailing edge flaps almost fully down) to slow down enough.

trevorishere··on Cobra Maneuver
It's an airshow maneuver. Speed is life. USAF (and presumably other AF's) send out 2 to 4 ship (or if we look at Desert Storm, over 70 ships). If you "stall" or perform this maneuver, whomever is behind you might overshoot, but his or her buddy will nab you.

Check out Stroke 3. This is an F-16 strike on an oil facility in Iraq. Stroke 3 avoided six Iraq (Russian-made) SAMs /without/ deploying any counter measures. Simply amazing to listen to.

https://www.youtube.com/watch?v=2uh4yMAx2UA

And here's a visual illustration of the entire strike package that went out. 76 aircraft as part of Package Q.

https://www.youtube.com/watch?v=zxRgfBXn6Mg

Fun (?) fact -- the first strike in Desert Storm was performed by eight Apache attack helicopters with two Pave Low helicopters leading them at NAP of the earth level at nighttime.

AIM-9X (https://en.wikipedia.org/wiki/AIM-9_Sidewinder#AIM-9X) has 90 degree off-boresight capabilities with helmet mounted displays, being able to pull 60Gs.

So not quite "backwards", but dang close. With that being said, beyond visual range (BVR) engagements for gen 4 and higher fighters (gen 4 would be F-16 (the best plane ever produced, and everyone here knows it ;), F-18, MiG-29, Su-27; gen 5 would be F-22, F-35... and somewhat arguably Su-57) should be the norm. The USAF/US Navy is a bit behind on this with the AIM-120C/D being a medium-range missile where as some of the Russian-produced missiles have a longer reach. The USAF currently has a program to produce a long-range variant of the AIM-120C/D (our last long range missile was the AIM-54 Phoenix, exclusively carried by the retired F-14) with the designation of AIM-260 -- the AIM-260 is expected to replace the AIM-120.

AIM-120C/D "maddog" call -- now that'd be an interesting air-to-air engagement -- "maddog" is the call for firing the AIM-120 without the aircraft having radar lock and whatever the missile picks up on it's terminal guidance radar is likely doomed.

Ahhh I played way too much Falcon 4.0 and the DCS F-16 module.

I've actually created this setup (in order to ditch Okta as it is far more expensive than AAD P1 if you want MFA).

You federate AAD and Okta. Sign in to Okta and it's smooth sailing into AAD-based resources like M365.

Okta puts on a good dog and pony show for execs. From a technical perspective, they're no better for corps (at least in first party auth or B2B -- I don't get into the B2C space). We found, for the apps we used, AAD as of ~4 years ago had better SCIM support (!) than Okta.

On top of getting O365 E5 + Ent Sec (I think they're just now called M365 E5) which gave us AAD P2 licenses, overall it was much cheaper than Okta. The goal was to just get MFA, which Microsoft gives away for free (with limited toggles) or in P1 licenses (with more toggles) where-as Okta wanted $6/user/month _just for_ MFA.

Microsoft puts on a terrible sales pitch, though. We were fortunate enough to have an _awesome_ Principal Program Manager spend days with us in-person answering all of our questions and explaining AAD to our IT management.

> we don't need Microsoft to make it even worse.

Microsoft made it better by preventing the scenario from occurring beginning 3 - 5 years ago.

trevorishere··on Does Company ‘X’ have an Azure Active Directory Tenant?
This is a legacy setup that can no longer be created. Microsoft removed the option to use a custom domain for Microsoft accounts many years ago, but hasn't forced people to change.

However, your friend can get out of this scenario by following the instructions on this site:

https://support.microsoft.com/en-us/account-billing/change-t...

They'll end up with <whatever_they_can_find>@outlook.com for their Microsoft account. When using Org services via a browser, you'll automatically use your Org account. When using consumer services, you'll automatically use your Microsoft account (assuming you've selected stay sign-in for both).

trevorishere··on On eating out alone
I was in a relationship for 18 years.
trevorishere··on On eating out alone
Not always, until the quietness and boredom sets in. You can only play games/watch YT/reddit/HN for so long.

I love being alone in the forest, though. I seek solitude on back logging roads -- places where people don't normally hike because it isn't 'pretty'.

Being alone in that context is freeing.

trevorishere··on On eating out alone
No, I don't experience the judgement effect.

Ended a very long relationship.

trevorishere··on On eating out alone
Eating out alone really hurts. It makes you feel that much more _alone_ because nearly everyone else is with their SO, a party, friend, etc. Bringing a phone is only a distraction to get through waiting for the meal to arrive.

I dislike it more than being alone at home.

trevorishere··on Why the Windows Registry sucks technically (2010)
I should add to this, as we know file system filters (e.g., anti-virus) slow down access to read (and write, but irrelevant here) files from any file system format on Windows (NTFS, FAT32, exFAT, etc), storing configuration data in configuration files would be less optimal, though minimal in terms of performance (given your app wasn't constantly re-reading the file). This wouldn't be the case with the Registry, as the hives are already open.
trevorishere··on Why the Windows Registry sucks technically (2010)
Do you know where Microsoft calls out the Registry as the current best practice in https://docs.microsoft.com/en-us/windows/apps/?
trevorishere··on Why the Windows Registry sucks technically (2010)
However, by default on NTFS, there will be 4096-N bytes of used space each time the specific hive needs to grow to accommodate those 10-100 bytes (this varied historically if we're talking about NT 4 and below, depending on volume size) due to format cluster size.

That said, it is still smaller than 100 files that are 10-100 bytes each taking up 4096 bytes, though with NTFS, those would be stored in the MFT anyways...

trevorishere··on Why the Windows Registry sucks technically (2010)
Application writers are free to use which ever format they choose on Windows, as well. The Registry is just yet another option -- Microsoft does not force developers to use it. I don't see the Unix convention as the more "liberal" one, here. It typically has _one less_ option.

trevorishere··on Long-term benzodiazepine use causes synapse loss and cognitive deficits in mice
Lamictal is not a benzo and must be used consistently (daily) to prevent SJS as it requires titration. Generally, those who need it (epileptic patients or those with bipolar disorder) must use it for the duration of their life.

> dementia in old age.

Spoke to a psychiatrist on this one. He was saying The Lancet longitudinal study was bunk and that Xanax use was not one of concern.

I'm not saying he's correct, but he literally laughed at my objection to Xanax, including it's now very long history of use with an average dose of 6mg/day.

trevorishere··on You're Not Losing Fat Because You're Eating Too Damn Much (2016)
Went from 230 to ~155 without exercise by calorie restriction alone (600-1200cal/day). It IS possible, though likely unhealthy to accomplish without exercise (I never, ask they say, consulted a doctor prior to the self-imposed restriction).

Exercise was uncomfortable until I had lost weight, now I can do 15+ mile hikes with a 60l backpack.

I don't want to discourage anyone from doing exercise at any time in their goal for weight loss, but it is possible to lose weight by calorie restriction alone.

trevorishere··on Current MFA fatigue attack campaign targeting Microsoft Office 365 users
It's not Azure, it is how your organization decides to implement MFA. The only time re-MFA'ing is 'required' is when your password expires (if it does) as your token expires.

Otherwise, you could have 365 day token lifetimes if your organization configured it. Or greater.
