[ Politics ] Open Question : Why didn’t Trump lock the country down in January to prevent deaths?

CNN)If the United States had started social distancing just a week earlier, it could have prevented the loss of at least 36,000 lives to the coronavirus, according to new research. As of Thursday, the outbreak’s death toll across the country has risen to 93,439. At least 1,551,853 cases of the disease have been recorded, according to data from Johns Hopkins University.

Is there a way to lock down a network?

If supposing I discover that my network is being attacked by some hacker or is being compromised in any way and I am able to detect it. So, is there any software-oriented way of ‘locking-down’ the network?

Basically, that means that there would be NO traffic at all in the whole network. A solution like yanking the model cable is not appreciated. Could it be somehow done in a more subtle way? blocking an IP address would not be the best because the person on the other end could spoof it or more certainly, could just get himself assigned another IP address by using other devices.

Could it be also done in a way as to only block traffic from that specific person so that legitimate traffic is not hindered? Maybe to identify him without something being easily changeable like IP or MAC address?

function to lock buddypress username from edit and automatically generate it

Was wondering if someone could recommend a function with buddypress that would both automatically change a user’s buddypress username to “First name” xprofile field + randomly_generated_characters as well as prevent the user from being able to change their username. I’m hoping this is possible because let’s just say our students are getting ‘creative’ with their usernames 🙂

Any help would be wonderful!

Thanks for this and all of the support you guys give us!

Name of ‘smart brute force’ attack against sequential cipher lock [duplicate]

I remember learning about an attack against sequential cipher locks – ones that don’t have a ‘reset’ or ‘enter’, you just enter digits and as soon as the last n consecutive entries match, the lock opens. So, if the code is ‘1234’, the sequence ‘32431234’ will work just fine.

The attack depends on a specific sequence that appends such digits that the resulting ‘tail’ of the string is as new as possible.

Let’s take for example a 3-digit binary lock. The possible codes are 000, 001, 010, 011, 100, 101, 110, 111. To try all 8 codes in standard brute force attack, you’d enter 24 digits total.

But instead, entering sequence 0001110100, 10 digits total, you cover all combinations and unlock the lock – generating sequences: 000, 001, 011, 111, 110, 101, 010, 100, each new digit past first 2 generating a new code.

For the good of me, I can’t recall the name of the sequence used for this sort of attack.

Friendly reminders for people who don’t lock laptops

My bosses have tasked me with coming up with a kind of “friendly reminder” card that we can leave on the desks of folks where we see they’ve walked away without locking their workstation and we have to lock it.

Has anyone else ever had to do something like this or do you have like a template email you have to send to people? The idea is to educate without coming off as overtly punitive.

Thanks in advance!

What does multiple castings of Arcane Lock on a door actually do?

If you cast Arcane Lock twice on a door, would the second spell take effect after the first one is suppressed?

I realise the effects do not stack but if two spells are active on a creature/object and one is suppressed the other is still active.

The way I see it is that if a door has two Arcane Lock spells cast on it, it would take two Knock spells to suppress it for 1 minute.

If a creature tried to pick a lock it would increase the difficulty by +10 (not +20), but would it need to roll twice to pick the lock?

As an alternative spell example, if a creature had Bless cast on it, the benefits would not stack, but both spells are active. If one caster loses concentration the effect of Bless would still be active.

Feel free to use other spell examples/scenarios in your answer, if you need. I am happy with any answers from published materials as well as Unearthed Arcana.

Thanks for your help with this.

Fully-secured screen lock in Ubuntu with encryption

I have Ubuntu 19.10 with full disk encryption. The encryption is effective as long as the system is turned off or restarted. Otherwise the data is unencrypted behind a locked screen which may not be very secured.

I wish to protect against:

  1. mechanisms that bypass screen lock (I have disabled SysRq, but there might be other ways too)
  2. cold boot attacks
  3. attacks through DMA, network, WiFi/Ethernet, physical ports, etc

What’s the best way to proceed? Can I have a home encryption on top of full disk encryption, and set the screen lock such that the same password will unlock and decrypt the home drive (I don’t want to enter two passwords)?

Is there any secure screen lock (no bug, no vulnerability against X11 crashes, etc)?

The OS + encryption should be able to protect the system 100 percent (except for cold boot attacks which mostly aren’t practical: the data rapidly deteriorates).

Thanks!

How can I lock rows for update without returning data over the connection?

I want to do something like this:

begin select * from foos where owner_id=123 and unread=true for update update foos set unread=false where owner_id=123 end 

In the statement where I acquire the lock, I don’t need any info about the rows. I just want to lock those particular rows. Is there a way to do this (elegant or hacky) which tells postgres to not do any of the work of actually giving me the data?

Can the spell Arcane Lock be used on objects like books or backpacks?

Having recently had to endure a nosy little halfling, my wizard is considering going ham with Arcane Lock. The spell states that casting it locks

a closed door, window, gate, chest, or other entryway, and it becomes locked for the duration.

Obviously, neither a book nor a backpack are an ‘entryway’. There are plenty of books (many modern day diaries or journals, for example) that come with a locking cover, and it makes sense to me that this spell would affect the lock of such a book. But what about an item without a built-in locking mechanism?

The spell description refers to the target of the spell as an object on several occasions. Since a book is a closeable object, would Arcane Lock work to lock the book shut? How about a belt pouch, or backpack?
