Image caching vs. image processing in PHP and S3 -

-

The thing here is right now I have this e-commerce web site where people can send many photos for their products. All images are stored on Amazon's S3. When we need thumbnails or some things, then I check on S3 if someone is available. If not, I do a process and send it to S3 and display it on the browser. Thumbnails of every different size are stored on S3, and checking the thumbnail availability for every request is to consume money. I am afraid that after paying more attention to the site, I will pay a lot (if it is ... ). Thinking of the option, I was thinking of placing the original pictures on the S3 only. Process the images flying on each request. I think that in this way I use the CPU, but I see a standard Not made me how far I can go. The thing is that I will not dismiss requests to make money and store more images on S3 and I can cache everything on the user's browser. I know it is not safe to do this, that is why I am bringing this question here.

What do you think? How do you think I can solve it?

Place the local cache of

:

  1. Which images in S3
  2. Cache of most popular images

Then in both cases you have a local reference if the image is not in the local cache, you can see the local cache You can check whether it is in S3 or not. Saves the S3 traffic for your most popular item and saves on latency while checking the S3 for one item in the local cache.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
