I am saving map images created in Adobe Illustrator as .svg documents. What are some tips and tricks for making the file size as small as possible? 回答1: Turn off "Preserve Illustrator Editing Capabilities", which includes an enormous proprietary pseudo-binary blob in your file. GZIP your content (either

问题 I stumbled to learn that my rails3.1 log file is super large, around 21mb. Is this, in terms of size normal? What the log file would like in the production environment? Besides, can I get rid of the log?thanks 回答1: you can just delete the file! Rails will create a new log if one doesn't exist. Obviously save / backup the file if it's important, but usually it's not. You can also zip the backuped up file (and then delete the source) if you want to keep it on the same drive but still save space

问题 I have a MySQL/PHP project that currently has a files table that creates virtual folders and links to uploaded files, the upload and accessing works fine, however i have just added the field 'size' and have amended my code to update the file size after upload into the table, however the code is not working. I get no errors and the file still gets uploaded but the code is inserting a null value into the relevant field. Code is below: global $dal; $tblDocs = $dal->Table("doc_files"); $fileArray

问题 I have a Python script that reads a file (typically from optical media) marking the unreadable sectors, to allow a re-attempt to read said unreadable sectors on a different optical reader. I discovered that my script does not work with block devices (e.g. /dev/sr0), in order to create a copy of the contained ISO9660/UDF filesystem, because os.stat().st_size is zero. The algorithm currently needs to know the filesize in advance; I can change that, but the issue (of knowing the block device

问题 I am building a prototype app with OpenCV. The app currently does not do anything but its apk file size is 6MB. The size is 10 times of normal app size. Is there any way to reduce this size? Update: I found out that as long as I use android native camera and interface with OpenCV in JNI/C++, the file size can be dependent on the methods you are using in the library. Current my test app with simple filter has size of 700K. 回答1: You can unzip your .apk file and find two versions of opencv_java

问题 I have a large set of directories for which I'm trying to calculate the sum total size of several hundred .txt files. I tried this, which mostly works: find . -name *.txt | xargs du -hc But instead of giving me one total at the end, I get several. My guess is that the pipe will only pass on so many lines of find's output at a time, and du just operates on each batch as it comes. Is there a way around this? Thanks! Alex 回答1: How about using the --files0-from option to du? You'd have to

问题 I'm running into a problem that I haven't seen anyone on StackOverflow encounter or even google for that matter. My main goal is to be able to replace occurences of a string in the file with another string. Is there a way there a way to be able to acess all of the lines in the file. The problem is that when I try to read in a large text file (1-2 gb) of text, python only reads a subset of it. For example, I'll do a really simply command such as: newfile = open("newfile.txt","w") f = open(

问题 This question is about using two different ways to insert objects into a Realm. I noticed that the first method is a lot faster, but the size result is huge comparing with the second method. The diference between the two approaches is moving the write transaction outside vs inside of the for loop. // Create realm file let realm = try! Realm(fileURL: banco_url!) When I add objects like this, the Realm file grows to 75.5MB: try! realm.write { for i in 1...40000 { let new_realm_obj = realm_obj

问题 I've read in apple's dev guide there's a limit for iOS app size, but I don't really understand it. It says this: iOS apps can be as large as 2 GB, but the executable file cannot exceed 60 MB. Isn't the executable file the whole app? I don't understand the difference between the 2 GB limit and the 60 MB limit. 回答1: The main part of the app is without a doubt the executable file. The executable is usually not very large, because it's just the compiled code that the machine runs. In small,

问题 Is there a way to get the size of a remote file like http://api.twitter.com/1/statuses/public_timeline.json in shell script? 回答1: You can download the file and get its size. But we can do better. Use curl to get only the response header using the -I option. In the response header look for Content-Length: which will be followed by the size of the file in bytes. $ URL="http://api.twitter.com/1/statuses/public_timeline.json" $ curl -sI $URL | grep -i Content-Length Content-Length: 134 To get the
