data-transfer

问题 We're making a quiz game. We have a question bank on a Google Drive Spreadsheet. We have a designer who has made a generic design for the question cards, in Photoshop. Now, can we somehow transfer the questions, with the corresponding answers, onto this design through some script, code, or any other automated process? I know there's a thing called PhotoshopScript, could that be worth taking a closer look at? 回答1: Yes, it can be done. A sample is this video that does something similar: https:/

问题 I am trying to use cURL for the first time to download some data. I am working with the cmd prompt in Windows 7. I have a txt file with lots of URLs where the files I want to download shoul be.

问题 I went through this answer here: Mysqldump of the AWS RDS But, apparently, it gave me no clue. What I intend to do? I have an RDS instance running on amazon and database is about 450+ tables, which is an insane amount of data for mysqldump. I wish to have it dumped so that I can migrate it from AwS to Dedicated. What is the problem? It freezes once I start taking the dump via adminer. Snapshot gives a format which can be used from one region to another but, I wish to have it in say.. SQL

问题 What is the difference between Data transfer costs and Bandwidth costs in AWS?? When I view my AWS bills, I see there are 2 types of expenses in Data Transfers tab, one of Data Transfer and one on Bandwidth costs. I tried to search a lot on this but could not get a clear demarcation on the difference between the two. 回答1: Yes, that is confusing! The top Data Transfer part seems to be data transfer between regions. From the Amazon EC2 pricing page: Data Transfer OUT From Amazon EC2 To Another

问题 How much data is transferred when I send the location to geofire table with geoFire.set("?????", [??.????, ??.????]) after the connection of the browser client has be set up? Somekey is a unique id up to 5 digits? down to the 4th digit (gives us an accuracy of 11m according to Measuring accuracy of latitude and longitude) We want to show a client with a fleet in public transport that it isn't really that much - but want to give facts. It would be nice to get the data every 5-10 seconds. 回答1:

问题 I'm attempting to transfer a large two dimensional array (17955 X 3) from my server to the client using Asynchronous RPC calls. This is taking a very long period of time which is especially bad because the data is needed in order to initialize the application. I've read that using a JSON object might be faster, but I'm not sure how to do the conversion in Java as I'm pretty new to the language and GWT, and I don't know if the speed difference is significant. I also read somewhere that I can

问题 Since Android api level 1, We can attach a MediaPlayer or Camera to the Surface with setDisplay or setPrewviewDisplay, then image data can be transfered to gpu and processed much faster. After SurfaceTexture is introduced, We can create our own texture with the target GL_TEXTURE_EXTERNAL_OES and attach the MediaPlayer or Camera to opengl es. These are well known, but what I want to talk about is the underneath which is about Android graphics architecture.(Android Graphics architecture) The

问题 I'm assuming that for every page request, the webserver (eg. Apache) creates a new instance of a script in memory. Can these instances communicate with each other while running? and pass data too? 回答1: If you want to pass data between scripts in PHP I suggest using either memcached or a database. Or possibly APC. If the scripts belong to the same session, they could theoretically communicate via the session but this would be effectively a one-way communication in most cases because only one

问题 My goal is to upload a image( .jpg or .png ) from client's folder to tomcat6 server through hessian protocol. And do image processing using opencv on server, then return the image back to client. Question1. Is the following transfering steps correct? put a test.jpg image on client's folder --> convert the test.jpg in client.java ( main.java ) class to BufferedImage --> convert the BufferedImage to mat or Iplimage in server for using openCV . I have set a hello world sample from Simple

问题 I am building an app which gets JSON-encoded data from a web server. Right now, anyone can access the server-script that gets the data, and potentially access sensitive data. So, what is the best way to ensure that the app is what's getting the data, and secure the traffic between the server and app? The server-script is PHP. Thank you. 回答1: You should use nonces Here's a great tutorial on how to generate an MD5 hash in C: http://www.saobart.com/md5-has-in-objective-c/ 回答2: So, what is the
