No. Your calculated landing speed doesn't change depending on the winds, so you'll always be touching down at roughly the same airspeed for the same aircraft type, weight, and flap setting. Touching down with a headwind just means

That they passed their minimums and still weren't set up correctly is shocking, yes. How can you commit to landing instead of going around when you're not configured for landing? The more egregious thing to me though is ignoring t

by aaronmdjones 6d ago
This is true for takeoffs but not for landings. You want to land with a headwind because this means that for the same airspeed you have a lower groundspeed, i.e. when you actually touch down you're going slower on the runway than if yo

RSA operations are performed modulo n, where n is the product of 2 primes. A 2048-bit RSA key is an n that is 2048 bits long (with the most significant bit set by definition). There are no consumer CPUs that have 2048-bit-wide registers; ev

The thing visible on the bus is the interface chip, not the sensor. Most cameras which I've seen hardwire their activity LEDs (it is impossible to grab stills or record video without lighting up the LED) do so by connecting the activit

Yes, but there are free resources available that guide you on how to go through the process without consulting a hallucination machine. Judges don't like their time being wasted, and they doubly don't like plaintiffs and defendant

I have to agree with GP here, this is pretty incredible. They contracted with a vendor to store their data, not to back it up. It's not a backup if you can lose it in the same instant you lose the data. You're right, they are. If

This is true, and yet DMARC v1 does not require you to use them in concert. Either one (a valid DKIM-signed message with sender alignment or a message that passes SPF checks with sender alignment) is enough to pass DMARC.

I'm afraid I don't know anything about ThinkPads. Hazarding a guess I'd say it's using Thunderbolt (hence the specific port requirement) which allows you to tunnel PCIe over it. Though it is odd that they wouldn't j

vPro requires the NIC to be connected directly to the PCH (over PCIe/CNV). This is going over USB, which won't cut it. An Intel WLAN card in an M.2 slot on the mainboard might work (given your givens; a vPro enabled chipset).

`errno` is a userland concept; the kernel returns negative error numbers that libc then turns into -1 and sets errno. Thus the correct manpage is errno(3).

You don't need any setuid binaries. You could just as easily use the vulnerability to add a job to crontab(5) that causes the cron daemon to run whatever you want as root.

If they don't have world-execute permission, an access(2) check for executability would return negative, leading to things like shells not tab-completing it. The kernel would also deny attempting to execute it, as it is not executable
