"How to get original image name from Microsoft Custom Vision API?",
"I'm unsure how to associate the tagged regions with my original image file names.\n\nFollowing the Custom Vision API documentation for GetTaggedImages request, I'm able to get a response with information about iteration id, created date, width, tagged regions, etc. However, there's no mention of the original image name. \n\nIf it's not possible to associate the original file name with the tagged regions, then I'll have to do my labeling offline (LabelImg for instance) and use the API to upload the tagged images - not the workflow I'm hoping for.\n\nThanks for any insights!"

"How does a client share a secret with an Intel SGX enclave instance, without letting the server hosting the enclave knowing it?",
"I am aware that there are SSL libraries available for SGX. But How to establish a secret between the SGX and the clients without letting the host knows it? Trivial methods fail, like: \n\nHave a public-private key pair built-in the SGX, then the client sends the session key to the SGX. The session key is encrypted by the public key of SGX. \n\nThis doesn't work because the host can get the private key directly from the compiled SGX enclave executable.\n\nRunning an https server in the SGX can neither do the trick, also because there is no authentication nor pre-shared secret between the SGX and clients."

This may be set on a per-axis basis to define each y-axis separately. If either limit is unspecified, it will be calculated automatically (e.g. c(NULL, 30) to automatically calculate just the lower bound).\n\n\nThanks!"

"Django query: Sort objects by the number of occurrences of a value?",

"Pagination in Oracle with dynamic query",
"I have a query that returns large amount of data. When users search for data in larger date ranges It can come up to 5 millions records, and when that happens app freezes for certain amount of time.\n\nSo I decided to do a pagination of query result, but I'm trying to do that without any DB changes. Let me explain:\n\nI have a stored procedure for retrieving all data, with dynamic SQL. Input parameters are 3 :\n\n\nVarchar for number of Select case (to choose which select should be executed),\nand 2 other Varchar parameters that select fields and condition of query, in other words - one before FROM and one after WHERE clause. These two parameters matter in this question.\n\n\nIn example, my procedure for calling query looks like this:\n\n\n first_parameter || ' FROM (...here is my query where all possible fields are selected with joins, db links etc.... ) WHERE ' ||\n second_parameter\n\n\nSo, I can modify start and end of query, and now I would like to modify It to enable pagination too, for let's say max 1.000 records at a time.\n\nI have tried to modify It in C# by adding a rownum in first_parameter along with selected fields \n\n\n (Select rownum, field1,field2 etc...)\n\n\n, and using \n\n\n rownum < 1000 in a WHERE clause\n\n\n. This actually works, but for a pagination I would need also to tell what row for start and end, like \n\n\n WHERE rownum > 1000 AND rownum < 2000\n\n\n, but this doesn't work. \n\nHow can I do this in Oracle 11g, where OFFSET is not available, can somebody show me ? I would prefer a solution without changing query inside of parameters If possible, since I can send everything I want into both parameters in question from C# in code (Varchar values ofcourse).\n\nP.S. : I have never done a pagination so forgive me If I wrote some silly things ;)"

"How to set custom rules like difficulty level for GameCenter to find match",
"Need to set dynamically some rules of game and inform possible players (while GC searches for players/automatch) about those rules before the player connects. Lets say I want to host/start a game and i want to set some starting amount of betting units (10...1000), level of difficulty(0...10), scoring system (0..3) etc. I imagine this like a table with cells providing this information so player decides if he/she wants to join and play game with such rules. How to implement it?\nAFAIK GKMatch uses only min and max number of players while searches for players and thats all. I could provide such information in invite but I need it for other players who r looking for game by themselves, like browsing existing games including rules. My game doesn't allow to join players since game is started but I need somehow to fill needed amount of players for session. Like if I want to play with only one player I start a game with number of players=2 (and some custom rules) so I need the GC to help me to find opposite player. And that player should be informed about my rules set before joining me."

The board has 4 pins - VCC GND TX RX. They're all connected to my sim900 hardware serial as follows: VCC=5V GND=GND TX=TX RX=RX (Yes I know that it's always actually TX=RX and RX=TX, but when I connect it that way my interface board doesn't blink any led to indicate a transfer whereas it does when I connect TX=TX and RX=RX). The switch on the module is set to hardware serial pins as well.\n\nSo the only thing that happens when I send AT commands such as AT or ATI and press enter is that puttys cursor comes back to the beginning of command that I typed. No response.\n\nI'm thinking that I'm not doing something that the arduinos software serial port is doing when it sends commands to sim900.\n\nCan anyone help please ?

"Comments on my design v3",

Each of these concrete classes will also inherit the Speed property from the IMovable interface, and each will have their own speed set. The whole abstract Bullet class and their concrete class derivatives is the strategy pattern.\n\nSome things I want to ask: The Ship and Invader class can only have one bullet at a time - but the Invader class can also have no bullets. This is e.g. when all the rows of aliens are still intact, then only the first row of aliens can fire bullets. The rows above them are not able to shoot. But how would I implement this in the Invader class? Should the bullet variable in the Invader class of the invaders who are not able to shoot be set or left to null? Or is there a better option?\n\nI hope I am getting closer and closer to getting the right design, all your comments are welcome!"

The resulting byte-code would have to play nicely with existing Lua byte-code that was compiled with the standard LoadString().\n\nTo be clear -- any difference would only occur at byte-compilation time. At runtime, the byte code would have no idea that anything different/unusual happened to it during the compile phase.\n\nWhat I have in mind sounds a lot like ActionScript; I wouldn't even mind an ActionScript compiler that outputs Lua byte code!\n\nHas anyone heard of such an effort?

I DO NOT want to have to pass in a pointer argument into getGlobalBig() because I want a function that returns an rvalue so that I could do stuff like:\nif(getGlobalBig().someField == 9) {\n // yay\n}\n\nI am also aware that I could do a single copy by skipping the unlocking of the variable, leaving that to the caller as a cleanup activity, but this is undesirable as I want to spend as little time as possible with the lock on.\nstruct big getGlobalBig(void) {\n // lock globalBig here...\n return *globalBig; // <------ copy #1 (directly into stack of caller, caller is responsible for unlocking)\n}\n\nSo based on those needs, is there a way to avoid the two copies?

"We have an MVC 5 WebApp and several class libraries all part of the same solution.\n\nThe WebApp is in Azure and we are using the StackExchange Redis as our caching.\n\nWe wanted to know if it is ok to add the Exchange Redis package to one of our class libraries instead of the WebApp. Will the connection string that is added to our Web.config file in the WebApp be accessible from our Library.\n\nMany thanks"
