I'm trying to find the total cost of a strategy by looking up the elements that make up that strategy from a table of unique item id's matched to development cost. If an item is in the strategy twice I only want to count the cost once. So strategy 1 would be the cost of Name 1, Name 5, Name 12 and Name 14. I've played around with this for ages trying various combinations of index match, lookup, and sumif but haven't quite cracked it. Let's block ads! بخوانید...

I'm looking for an easy (!) way to encrypt (and decrypt) USB volumes under Windows 10. Easier than my current practise: Currently, I've an True Crypt file on the USB volume and a portable TrueCrypt installation on the same stick. I plug the device in, run TC, select the TC file (have to reselect it, since the device has mostly new drive letters), select a drive letter to mount, and click ok, enter the password, ok. Have the new volume with encrypted files in/on. What I want: Plug the device in -...

I have a table array $E$14:$G$851. Column E just contains unique identifiers, lets say a/b/c/d etc, column F contains hundreds of numbers all less than or equal to 20 and column G contains the values I need retued. I need a formula which will search for the unique identifier in column E, and then search UP column F and find me the FIRST value that is LESS THAN the column F result and use that result to retu the adjacent value in column G. So if I had searched for "g", the formula would then sear...

I am the 'accidental admin' for a small but growing charity. We have a Windows Server 2012 R2 running on a single, newish server plus 8 workstations - 6 with Windows 7 Pro and 2 with Windows 10. The single server is simply a file server & not a domain controller. Each user has a simple setup, they are users on the server and have shares that they access as mapped network drives. However with a growth in volunteers I'm being asked to setup the same user on several PCs, so the volunteers have ...

When I was told about how computers establish a connection (using TCP), I leaed about the "three way handshake", in a way that I understood exactly what the packets were saying: Computer A: Sends "SYN" -- asking if "anyone's there" Computer B: Sends back "SYN ACK" -- confirming there is Computer A: Sends back "ACK" -- making sure B knows their message made it back to A. It made it really easy for me to understand, and explain to others later. I'd like to know if there's a similar way of expla...

I have a simple LAN configured on Thomson TWG870 modem/router. The LAN stations have by default (that's without any explicit configuration in router panel).

How do I get --ntasks-per-node to work with job arrays? I have a test where I submitted a job array of 1-5000 using --ntasks-per-node=2 onto a grid with 36 nodes appearing in sinfo... and it's running >1000 jobs at a time. I've also tried using --tasks-per-node, --ntasks, etc, even tried both --ntasks=1 and --ntasks-per-node=2 and nothing limits it. I'm guessing Slurm's model of this is messed up and "arrays" don't count against the number of tasks so, while each individual job within an arra...

I am building a small system that has one embedded computer and one etheet device. The embedded computer has a fixed IP address (from the manufacturer), but the etheet device uses DHCP to get its address. Is there a fast and easy way to let the embedded computer give the device an address? It runs Debian, but I want to try to avoid to use apt-get to download new packages, as it will be extra work (connecting the inteet, setting routes, etc) when building more of these systems. I am thinking of a...

They're looking for a backup solution that's simple yet offers perfect protection from ransomware. There's no ...

As a graphic designer, I have a large number of fonts installed on my PC (WIN XP SP3). I need the variety, but the many fonts slow my applications considerably. Is there a simple way to organize fonts into multiple folders and switch between them, preferably from within applications? The only way I know to swap font files is to organize the fonts into folders, and rename the folders to "Fonts" as I need each one. That would be terribly cumbersome. Let's block ads! بخوانید...

At my workplace, I have taken over maintainance and development responsibilities of a C# windows desktop application. The application is compiled into a .exe-file, and linked to from our intranet page. When deploying new versions of the application, the standard procedure has been to delete the old file, and simply replace it with the new one. However, the number of users are increasing, and it is becoming hard to find a time of day where no users has the application open. I have researched a bi...
