I will need to have a maximum of 10 concurrent coections. I will use: PostgresSQL for my db Hibeate for ORM Server application that manages the db Client applications that coect to the the server app and send requests My questions: Is that a good way of organising the structure? From my research it seems that hibeate is single threaded; Is it a good idea then to setup a FIFO request queue (on the server app) that will take the requests from multiple threads(clients) and retu the results in order OR is th...

Vote count: 0 Evening All, I am extracting data from a API which exposes records as properties of the class so an example would be For Each entry As Webservice.Names In objResponse.results string = string & "'firstname'=" & entry.firstname string = string & "'suame'=" & entry.suame next now we have about 50 entities in the webservice, and each has at least 10 "fields" my question is can I expose properties any other way ? i.e. could i For Each entry As Webservice.Names In objResponse.results for each prop in entry.properties string = string & "'" & prop.name & "'=" & entry.fields(prop.name) next next or similar, i can't seem to expose the properties above, but really looking for a way that i...

Vote count: 0 We are just begiing to use Avi in AWS and I am setting up the controller instance. As I am adding users to the controller instance I would like for users that log in to the instance via shell do so with private/public keypair authentication. I created a user and added their public key to ~/.ssh/authorized_keys , I also added a NOPASSWD entry, but it seems to still be prompting for a password. Can I log in to the GUI with a password but restrict shell access to keypair only? asked 6 mins agomattdlh Let's block ads! بخوانید...

Vote count: 0 Using C# and .NET 4.5: I am looking for a simple and efficient option to use the windows user and current machine to encrypt/decrypt a string. The encrypted string can be decrypted on the very same machine with the same logged-in user only. Other users logged-in to the same machine must not be able to decrypt. The same user logged into another machine must not be able to decrypt. Back in 2002, I used to use DPAPI to do the similar thing. I expect there is a more mode option in 2016 with .NET 4.5 with single line of API call :) Thank you, asked 39 secs agoAllan Xu Let's block ads! بخوانید...

Vote count: 0 I am trying to take a screenshot of the whole screen and would like to send it over the network to a server. (the server will be the one to save it) I am currently using this code HBITMAP hBitmap = CreateCompatibleBitmap(hScreen, w, h); CImage image; image.Attach(hBitmap); image.Save(L"screen.jpg"); It does save the file, but that's not what I want. I'm also not sure how to get the bytes, I was thinking of GetBits() but the documentation says it is a pointer to the data of the underlying Bitmap. What I want to get is the JPG data which I can send through the network and save the image using the server. So, why am I not just using bitmap and sending it directly? because it is a ...

Vote count: 0 I was searching for .NET memory leak detection tools and .NET profilers - on inteet there is plenty of them, however - they are all commercial tools. I would like to check if there is any open-source alteative, what is their development status (what is working and what is not working), and if it's possible - if someone could pinpoint me to which API's are used to "hook" .NET garbage collector. Also I've understood that reference analysis is non-trivial - if GC does not collect memory - then it means that someone references that data - so that in a tu requires some sort of reference backtracking - also interesting what API's and techniques exists to analyze references. I would p...

For a particular node N1, I want to find the root node of the tree it resides in (its ancestor that has a degree of 0). Is there an easy way to do this in network x? I looked at: Getting the root (head) of a DiGraph in networkx (Python) But there are multiple root nodes in my graph.

Vote count: 0 pic of the problem I have a problem. I'm making a simple unet game for 2 players. They should face each other and the host should be on the left and the client on the right. Round Robin only works with the host discoects and re-run. But first thing first, inside the tank's script in OnStartLocalPlayer() I make the check if the player was spawned in the left side or the right (simple transform.position.x is greater than a value or not). The host flip both to the wrong direction and the client sees the right direction but the tanks shoot from their behinds (as the host sees this). The player prefab is a red tank facing right (blue is colored also in OnStartLocalPlayer() to make o...
