This is something that has always been bugging me as a feature of C++ lambda expressions: The type of a C++ lambda expression is unique and anonymous, I simply cannot write it down. Even if I create two lambdas that are syntactically exactly the same, the resulting types are defined to be distinc...

Two pointed, connected CW complexes with the same homotopy groups need not be homotopy equivalent (Are there two non-homotopy equivalent spaces with equal homotopy groups?). Moreover, having the same homotopy and homology groups is also not enough (Spaces with same homotopy and homology groups th...

I have reason to suspect that a user may be accessing their company email using a copy of Microsoft Outlook (or perhaps another email client) from a personal device for the purpose of data exfiltration. I've ruled out them accessing their account using ActiveSync (using Get-ActiveSyncDeviceStatis...

I was using this command to read the temperature of cpu: cat /sys/class/thermal/thermal_zone0/temp Then I was looking for some other options and suddenly found that there is another option to find out core temperature. Since this CPU has two cores I am seeing temperature range of thermal_zone0 - ...

Let $\mathbb{S}_m$ the symmetric group on $m$ letters. Let $v\in\mathbb{S}_m$, and consider paths in the Bruhat order like this: $1\lessdot v_1\lessdot\cdots\lessdot v$, where $\lessdot$ means the covering relation in the (strong) Bruhat order. Let $N_v$ be the number of such paths. It is intuiti...

There is some file, like file.txt, and I want to append COPY at the end of the filename, like fileCOPY.txt. Give me a command for this in the Ubuntu terminal. I have tried the mv command like mv file.txt fileCOPY.txt, but this does intend to do what I mean.

When an integer is converted to floating-point, and the value cannot be directly represented by the destination type, the nearest value is usually selected (required by IEEE-754). I would like to convert an integer to floating-point with rounding towards zero in case the integer value cannot be d...

So I have a df like this In [1]:data= {'Group': ['A','A','A','A','A','A','B','B','B','B'], 'Name': [ ' Sheldon Webb',' Traci Dean',' Chad Webster',' Ora Harmon',' Elijah Mendoza',' June Strickland',' Beth Vasquez',' Betty Sutton',' Joel Gill',' Vernon Stone'], 'Performance':[33,64,142,116...
