    tar -cvzf filename.tar.gz directory_to_compress/

Most `tar` commands have a `z` option to create a `gzip`ed version. 



Though seems to me the question is how to circumvent Google. I&#39;m not sure if renaming your output file would fool Google, but you could try. I.e.,

    tar -cvzf filename.bla directory_to_compress/

and then send the `filename.bla` - contents will would be a zipped tar, so at the other end it could be retrieved as usual.



To bypass google&#39;s check, which is what you really want, simply remove the extensions from the file when you send it, and add them back after you download it.
For example:

 - tar czvf file.tar.gz directory 
 - mv file.tar.gz filetargz 
 - [send filetargz via gmail]
 - [download filetargz]
 - [rename filetargz to file.tar.gz and open]

Another easy way to circumvent google&#39;s check is to use another compression algorithm with tar, like bz2:

    tar -cvjf my.tar.bz2 dir/

Note that &#39;j&#39; (for bz2 compression) is used above instead of &#39;z&#39; (gzip compression).

Try this:

    tar -czf my.tar.gz dir/

But are you sure you are not compressing some .exe file or something? Maybe the problem is not with te compression, but with the files you are compressing?

With flash on the way out in many environments (iPhone, Android, IE10, etc...), is there any new solution forthcoming in any browsers that will allow a safe copy of information to the clipboard without flash installed?

I&#39;ve been using [ZeroClipboard][1] so far, but I&#39;m worried about more viewers that don&#39;t have flash and this functionality is going to be broken and I&#39;d love to not depend on Flash whenever possible.

I have two scripts 1.sh and 2.sh.

1.sh is as follows:

    export variable

2.sh is as follows:

    #!/bin/sh

According to what I read, doing like this (export) can access the variables in one shell script from another. But this is not working in my scripts. Can somebody please help. Thanks in advance.

How stable is s3fs to mount an Amazon S3 bucket as a local directory in linux? Is it recommended/stable for high demand production environments?

Are there any better/similar solutions?

**Update:** Would it be better to use EBS and to mount it via NFS to all other AMIs?

Is there a way to include another shell script in a shell script to be able to access its functions?

Like how in PHP you can use the `include` directive with other PHP files in order to run the functions that are contained within simply by calling the function name.

I want to cross compile the Qt libraries (and eventually my application) for a Windows x86_64 target using a Linux x86_64 host machine. I feel like I am close, but I may have a fundamental misunderstanding of some parts of this process.

I began by installing all the mingw packages on my Fedora machine and then modifying the `win32-g++` qmake.conf file to fit my environment. However, I seem to be getting stuck with some seemingly obvious configure options for Qt: `-platform` and `-xplatform`. Qt documentation says that `-platform` should be the host machine architecture (where you are compiling) and `-xplatform` should be the target platform for which you wish to deploy. In my case, I set `-platform linux-g++-64` and `-xplatform linux-win32-g++` where linux-win32-g++ is my modified win32-g++ configuration.

My problem is that, after executing configure with these options, I see that it invokes my system&#39;s compiler instead of the cross compiler (x86_64-w64-mingw32-gcc). If I omit the `-xplatform` option and set `-platform` to my target spec (linux-win32-g++), it invokes the cross compiler but then errors when it finds some Unix related functions aren&#39;t defined.

Here is some output from my latest attempt: http://pastebin.com/QCpKSNev.

Questions:

 1. When cross-compiling something like Qt for Windows from a Linux host, should the native compiler *ever* be invoked? That is, during a cross compilation process, shouldn&#39;t we use *only* the cross compiler? I don&#39;t see why Qt&#39;s configure script tries to invoke my system&#39;s native compiler when I specify the `-xplatform` option.

 2. If I&#39;m using a mingw cross-compiler, when will I have to deal with a specs file? Spec files for GCC are still sort of a mystery to me, so I am wondering if some background here will help me.

 3. In general, beyond specifying a cross compiler in my qmake.conf, what else might I need to consider?


How do I configure Qt for cross-compilation from Linux to Windows target?

Can GNU tar add many files to an archive, deleting each one as it is added?

This is useful when there is not enough disk space to hold both the entire tar archive and the original files - and therefore it is not possible to simply manually delete the files after creating an archive in the usual way.

**TL;DR;**

Is there a way to compress an image (mostly jpeg, png and gif) directly browser-side, before uploading it ? I&#39;m pretty sure JavaScript can do this, but I can&#39;t find a way to achieve it.

&lt;br /&gt;
Here&#39;s the full scenario I would like to implement:

- the user goes to my website, and choose an image via an `input type=&quot;file&quot;` element,
- this image is retrieved via JavaScript, we do some verification such as correct file format, maximum file size etc,
- if every thing is OK, a preview of the image is displayed on the page,
- the user can do some basic operations such as rotate the image by 90&#176;/-90&#176;, crop it following a pre-defined ratio, etc, or the user can upload another image and return to step 1,
- when the user is satisfied, the edited image is then compressed and &quot;saved&quot; locally (not saved to a file, but in the browser memory/page),-
- the user fill a form with data like name, age etc,
- the user click on the &quot;Finish&quot; button, then the form containing datas + compressed image is sent to the server (without AJAX),

The full process up to the last step should be done client side, and should be compatible on latest Chrome and Firefox, Safari 5+ and **IE 8+**. If possible, only JavaScript should be used (but I&#39;m pretty sure this is not possible).


I&#39;ve not code anything right now, but I&#39;ve thought about it already. File reading locally is possible via [File API][1], image previewing and editing could be done using [Canvas][2] element, but **I can&#39;t find a way to do the image compression part**.

According to [html5please.com][3] and [caniuse.com][4], supporting those browser is quite hard (thanks to IE), but could be done using polyfill such as [FlashCanvas][5] and [FileReader][6].

Actually, the goal is to reduce file size, so I see image compression as a solution. But, I know that uploaded images are going to be displayed on my website, every time at the same place, and I know the dimension of this display area (eg. 200x400). So, I could resize the image to fit those dimensions, thus reducing file size. I have no idea what would be the compression ratio for this technique.

What do you think ? Do you have any advice to tell me ? Do you know any way to compress an image browser-side in JavaScript ? Thanks for your replies.

How to compress an image via Javascript in the browser?

I&#39;m trying to create a ZIP archive with a simple demo text file using a `MemoryStream` as follows:

    using (var memoryStream = new MemoryStream())
    using (var archive = new ZipArchive(memoryStream , ZipArchiveMode.Create))
    {
        var demoFile = archive.CreateEntry(&quot;foo.txt&quot;);

        using (var entryStream = demoFile.Open())
        using (var streamWriter = new StreamWriter(entryStream))
        {
            streamWriter.Write(&quot;Bar!&quot;);
        }

        using (var fileStream = new FileStream(@&quot;C:\Temp\test.zip&quot;, FileMode.Create))
        {
            stream.CopyTo(fileStream);
        }
    }

If I run this code, the archive file itself is created but *foo.txt* isn&#39;t.

However, if I replace the `MemoryStream` directly with the file stream, the archive is created correctly:

    using (var fileStream = new FileStream(@&quot;C:\Temp\test.zip&quot;, FileMode.Create))
    using (var archive = new ZipArchive(fileStream, FileMode.Create))
    {
        // ...
    }

Is it possible to use a `MemoryStream` to create the ZIP archive without the `FileStream`?

I normally compress using `tar zcvf` and decompress using `tar zxvf` (using gzip due to habit). 

I&#39;ve recently gotten a quad core CPU with hyperthreading, so I have 8 logical cores, and I notice that many of the cores are unused during compression/decompression. 

Is there any way I can utilize the unused cores to make it faster?
