Obtaining the dual variables of an optimisation problem with second order cone constraints solved using Gurobi

I’m solving an optimisation problem with linear and second order cone constraints, in other words the problem is convex and should have dual variables. I’m using Julia with JuMP to formulate the optimisation problem and I’m solving the problem with Gurobi. From the JuMP documentation, it should be possible to obtain the dual variables using the function dual. However I obtain NaNs when I do this while a linear version of my problem returns the duals as expected. Can anyone explain to me why this is and possible work arounds?

Add second trusted voice to Google Pixel

Is it possible to add a second “trusted voice” to my Google Pixel so that a second person can say “OK Google” to unlock my phone? I would like to do this so that my phone can act like a substitute for Google Home when I’m at home–in order to enable my partner to unlock through “OK Google”, but still restrict it to our two voices only.

If it isn’t possible to do through a single user, is it possible that setting up a second user will allow this? I’m not familiar with how switching between users works on Android yet.

Prevent “invoked too many times per second” error in Google Apps Script

I have a Google spreadsheet consisting of different months on each tab. Every month, I add a new tab and another 50-75 rows. There are many tabs. There is a cell on each row which calls a custom function, like this:

=myFunction(A1) 

The problem I am having is that I am getting the following error:

error: Script invoked too many times per second for this Google user account.

What can I do to prevent this error from occurring?

Is the problem because there are too many tabs, or too many rows per tab?

There must be a way to prevent the function from having to run more than once.


Here is a shortened version of the function that is called:

function myFunction(expense) { if (   InStr(1,expense,"CPC SCP") ||   InStr(1,expense,"CPC/SCP") ||   InStr(1,expense,"xxxx")   )   { category = "5530 - Postage Expense" }     else if (   InStr(1,expense,"PRE-AUTHORIZED PAYMENT") ||   InStr(1,expense,"xxx ")   )   { category = "9999 - Payment" }     else if (   InStr(1,expense,"PURCHASE INTEREST") ||   InStr(1,expense,"RETURNED PAYMENT FEE") ||   InStr(1,expense,"xxxx")   )   { category = "5070 - Bank Charges" }   else { category = "Not Sure" }  return category;    }  

ATL to MAD, 1 hour stop in PHL with terminal change – Do I have to go through security a second time?

I have a flight on AA from Atlanta to Madrid. My booking lists a “stop” in Philadelphia for approximately one hour and 15 minutes. I’m concerned because my itinerary lists arrival in PHL at terminal A but departure from terminal B, and the airline switches to Iberia. Will I need to go through security again before leaving PHL? I’m worried about the short stop time.

Drawing a second weapon as part of an attack?

Consider a 1st level Rogue who wants to fight with two shortswords using Two-Weapon Fighting (PHB p.195) but does not have the Dual Wielder Feat.

Starting off empty-handed, is the following possible?

Round 1) Free Interaction: Draw first shortsword Action: Attack with first shortsword

Round 2) Free Interaction: Draw second shortsword Action: Attack with first shortsword Bonus: Attack with second shortsword

Rounds 3+) Continue happily attacking with both weapons

Or do I need to “Use an Object” on the first round to prep for the Two-Weapon Fighting?

Thanks.

Does a +1 shield allow me to add 3 to my Dex saves when using the second benefit of Shield Master?

If I have a +1 shield and the Shield Master feat (PHB, p. 170), can I add 3 to my Dex saving throw when I use the second benefit of Shield Master?

If you aren’t incapacitated, you can add your shield’s AC bonus to any Dexterity saving throw you make against a spell or other harmful effect that targets only you.

Recent second canadian citizenship travelling to USA

So i just got my canadian passeport… I used to travel to USA with my tunisian passeport (green passeport with arabic letters) needless to say that i get double checked (second inspection) every single time I go through customs with some weird questions from random agents (they can be cool agents but also rude ones ) … My question is as follows : If the guy asks me if I already got a passeport before my canadian one do I have to answer? Does he have the right to ask me that question? (Btw in order to avoid any issues I might just asks/do whatever he gonna ask me)

Thanks

Two IP interface private in access mode and second one in a trunk mode, the second doesn’t works

I have two interfaces one of them is ens160 in access mode and the second one is ens192 in trunk mode with vlan 600 and ip pool of 192.26.124.104/29 i have done this netplan in ubuntu 18.04. The first interface is ok but the second one doesn’t works. The router don’t show me the mac address. Any suggestion?

Netplan is like this:

network:     versión: 2     renderer: networkd     ethernets:         ens160:             addresses:             - 10.203.22.107/27             gateway4: 10.203.22.97             nameservers:                 addresses:                 - 8.8.8.8         ens192: {}      vlans:         vlan.600:             id: 600             link: ens192             addresses: [192.26.124.104/29]             gateway4: 192.26.124.105             nameservers:               addresses: [8.8.8.8, 8.8.4.4]             dhcp4: yes 

Is it possible to mirror only one space or one app to a second monitor/screen?

Specifically, I would like to be able to switch spaces on my laptop while the monitor mirrors only one of those spaces – specifically for presentation purposes.

That is to say, imagine my laptop has 5 spaces – Desktop 1, Desktop 2, etc. I would like to be able to mirror Desktop 1 to the monitor or screen but still be able to switch to Desktops 2-5 on my laptop without the monitor’s space changing. Alternatively, is there a way to mirror only a single instance of, say, Chrome or Firefox in fullscreen?
