  • Resuming File Downloads in Ruby on Rails

    - by jaycode
    Hi, this has been asked here: http://stackoverflow.com/questions/1840413/resuming-file-downloads-in-ruby-on-rails-range-header-support But there was no answer. I am having similar problem, could anybody help, please? Thanks before. Alright I am getting close. Seems like I need to setup header Content-Length or Content-Range, as described here: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.13. Haven't got an idea how. Anybody knows? Jay response.header["Content-Range"] = "20000-#{size}" send_file "#{Dir.pwd}/products/filename.zip", :type => 'application/zip', :size => (size - 20000) doesn't work

  • NoSQL as file meta database

    - by fga
    I am trying to implement a virtual file system structure in front of an object storage (Openstack). For availability reasons we initially chose Cassandra, however while designing file system data model, it looked like a tree structure similar to a relational model. Here is the dilemma for availability and partition tolerance we need NoSQL, but our data model is relational. The intended file system must be able to handle filtered search based on date, name etc. as fast as possible. So what path should i take? Stick to relational with some indexing mechanism backed by 3 rd tools like Apache Solr or dig deeper into NoSQL and find a suitable model and database satisfying the model? P.S: Currently from NoSQL Cassandra or MongoDB are choices proposed by my colleagues.

  • How to organize my site's file system properly?

    - by Wolfpack'08
    Doing some reading on Stack Overflow, I've found a lot of information suggesting that proper organization of a file system is crucial to a well-written web app. One of the key pieces of evidence is high-frequency references to "separation of concerns" in questions related to keeping programs organized. Now, I've found some information on organizing file systems (Filesystem Hierarchy Standard) from 2004. It raises only two concerns: first, the standard's a bit dated, so I believe it may be possible to do better given the changes in technology over the past 8 years; second, and most important, my application is very small compared to an entire Linux distro. I think that the file system should be organized very differently because of that. Here's what I'm looking at, currently: /scripts, /databases, /www -> /dev, /production -> login, router, admin pages, /sites -> content types, static pages /modules, /includes, /css, /media -> /module-specific-media

  • Does this file format exist?

    - by Jon Chase
    Is there a file format that handles the following use case... I'd like to create a tar file (or whatever - I'm just using tar here b/c it's a well known file format for containing multiple files) that would be usable even if I only had access to specific chunks of said file. For example, say I tar up my mp3 and photo collection into a 100GB tar file, then put the file into some long term storage somewhere. Later, I want to access a specific mp3 file. I don't want to download the entire 100GB tar file just to get to one mp3. In fact, let's say I can't download the entire 100GB tar file. Instead, I'd like to say "give me megabytes 10 through 19 of the 100GB tar file" and then have the mp3 magically extracted from those 10 megabytes. Does a file format like this exist?

  • Foremost custom file type not accepted by -t argument

    - by Channel72
    I'm trying to recover a deleted file on an ext3 file system using the foremost utility. The file I want to recover is a hpp C++ source code file. However, foremost does not automatically support the hpp file extension, so I have to add it to the config file. So, following the instructions on the man page, I add the following line to the config file: hpp n 50000 include include ASCII Then I run foremost as follows: $foremost -v -T -t hpp -i /dev/md0 -o /home/recover/ Instead of doing anything, it just displays the help message. If I change the hpp to htm or jpg, it works. So apparently foremost isn't accepting the custom file type I added into the config file. But I've looked over this dozens of times now, and I can't see what I'm doing wrong. I'm following the instructions exactly. Why doesn't foremost recognize the new file type I added to the config file?

  • Need a solution to store images (1 billion, 1000,000,000) which users will upload to a website via php or javascript upload [on hold]

    - by wish_you_all_peace
    I need a solution to store images (1 billion) which users will upload to a website via PHP or Javascript upload (website will have 1 billion page views a month using Linux Debian distros) assuming 20 photos per user maximum (10 thumbnails of size 90px by 90px and 10 large, script resized images of having maximum width 500px or maximum height 500px depending on shape of image, meaning square, rectangle, horizontal, vertical etc). Assume this to be a LEMP-stack (Linux Nginx MySQL PHP) social-media or social-matchmaking type application whose content will be text and images. Since everyone knows storing tons of images (website users uploaded images in this case) are bad inside a single directory or NFS etc, please explain all the details about the architecture and configuration of the entire setup of storage solution, to store 1 billion images on any method you recommend (no third-party cloud storage like S3 etc. It has to be within the private data center using our own hardware and resources.). The solution has to include both the storage solution and organizing the images uploaded by users. How will we organize the users images if a single user will not have more than 20 images (10 thumbs and 10 large of having either width or height 500px)? Please consider that this has to be organized in a structural way so we can fetch a single user's images via PHP/Javascript or API programmatically through some type of user's unique identifier(s).

  • What You Said: How Do You Sync Your Files Between Your Devices?

    - by Jason Fitzpatrick
    Earlier this week we asked you to share your tricks and techniques for keeping files synced between your different devices. Now we’re back to highlight how you do it. Overwhelmingly, you do it with Dropbox. Despite the proliferation of different platforms there has been little inroads made into any sort of universal syncing. We heard from quite a few different readers and by far the most popular option was to use Dropbox to ensure that you could get the music and documents you wanted whether you were on your desktop, laptop, netbook, iPhone, or Android device. In the same breath however, nearly all of your added on an additional service. The real message, it would seem, is that there simply isn’t a service good enough to meet all of the needs most users have, all of the time. The most common response to our Ask the Readers question was “Dropbox and…”; this pattern is illustrated nicely in the following quotes. Kim writes: Dropbox for all kinds of things. (Would also use Sugarsync, but it doesn’t support Linux.) Lastpass for passwords. Xmarks for bookmarks, although I’m going to try Firefox Sync soon. Evernote for things like shell commands I might want someday. Google Beta for music, once I get it uploaded. I have an Amazon account too, but Google gives you more space. Gmail. Michael finds himself in a similar situation and writes: How to Make and Install an Electric Outlet in a Cabinet or DeskHow To Recover After Your Email Password Is CompromisedHow to Clean Your Filthy Keyboard in the Dishwasher (Without Ruining it)

  • Storing lots of large strings with frequent "appends" and few reads

    - by Thiago Moraes
    In my current project, I need to store a very long ASCII string to each instance of a given object. This string will receive an 2 appends per minute and will not be retrieved so frequently. The worst case scenario is a 5-10MB string. I'll have thousands of instances of my object and I'm worried that storing all those strings in the filesystem would not be optimal, but I can't think of a better solution. Can anyone suggest an alternative? Maybe a key-value store? In this case, which one? Any other thoughts?

  • Trying to figure out SDL pixel manipulation?

    - by NoobScratcher
    Hello so I've found code that plots a pixel in an SDL Screen Surface : void putpixels(int x, int y, int color) { unsigned int *ptr = (unsigned int*)Screen->pixels; int lineoffset = y * (Screen->pitch / 4 ); ptr[lineoffset + x ] = color; } But I have no idea what its actually doing here this is my thoughts. You make an unsigned integer to hold the unsigned int version of pixels then you make another integer to hold the line offset and it equals to multiply by pitch which is then divided by 4 ... Now why am I dividing it by 4 and what is the pitch and why do I multiply it?? Why must I change the lineoffset and add it to the x value then equal it to colors? I'm soo confused.. ;/ I found this function here - http://sol.gfxile.net/gp/ch02.html

  • TDD with SQL and data manipulation functions

    - by Xophmeister
    While I'm a professional programmer, I've never been formally trained in software engineering. As I'm frequently visiting here and SO, I've noticed a trend for writing unit tests whenever possible and, as my software gets more complex and sophisticated, I see automated testing as a good idea in aiding debugging. However, most of my work involves writing complex SQL and then processing the output in some way. How would you write a test to ensure your SQL was returning the correct data, for example? Then, say if the data wasn't under your control (e.g., that of a 3rd party system), how can you efficiently test your processing routines without having to hand write reams of dummy data? The best solution I can think of is making views of the data that, together, cover most cases. I can then join those views with my SQL to see if it's returning the correct records and manually process the views to see if my functions, etc. are doing what they're supposed to. Still, it seems excessive and flakey; particularly finding data to test against...

  • Graphical Interface and Object Selection/Manipulation

    - by ToriArendt
    I have a project I want to try to implement, but I'm kind of stuck on how to get started. I know there are probably a lot of resources that I can look at, but I'm really just stuck on what to even search for and where to begin. Basically, I have a program written in Java that separates 3D coordinates from a 3D reconstructed model into different objects. I then want to be able to perform a logistic regression on these objects to determine if they are type A or type B. But first, I need to classify a training set of objects as type A or B by hand. I don't know ANYTHING about graphing or user interfaces in Java, so I have been plotting the coordinates of a given object in MATLAB so that I can visualize the object and assign it a type. Now, as I am trying to make this program more "user friendly" I want to create an interface in Java where I can simply graph all the coordinates of the objects from the entire 3D model (on the same graph). I then want to be able to click on the each object and assign it to be either of type A or type B. I hope this description makes sense and someone can point me in the direction of something that will help me. I'm sorry if some of this terminology is off; I'm a bit new to software development. P.S. If anyone also has some tips on implementing logistic regression in Java, I'm sure I'll need them down the road :).

  • Delete temp file during finally vs delete output file during catch

    - by Russell
    This is in Java 6. I've seen more than once that people create temp files, do something, then rename it to the output file. Everything is wrapped in a try-finally block, where the temp file is deleted in finally in case something goes wrong in between. try { //do something with tempFile //do something with tempFile //do something with tempFile tempFile.renameTo(outputFile); } finally { if (tempFile.exists()) tempFile.delete() } I was wondering what are the benefits of doing that instead of doing something to the output file directly and delete it in case of exceptions. try { //do something with outputFile //do something with outputFile //do something with outputFile } catch (Exception e) { if (outputFile.exists()) outputFile.delete(); } My guess is that deleting temp files in finally benefits me when the try block can throw many kinds of exceptions. Is my guess right? What else?

    Okay, mkstemp is the preferred way to create a temp file in POSIX. But it opens the file and returns an int, which is a file descriptor. From that I can only create a FILE*, but not an std::ofstream, which I would prefer in C++. (Apparently, on AIX and some other systems, you can create an std::ofstream from a file descriptor, but my compiler complains when I try that.) I know I could get a temp file name with tmpnam and then open my own ofstream with it, but that's apparently unsafe due to race conditions, and results in a compiler warning (g++ v3.4. on Linux): warning: the use of `tmpnam' is dangerous, better use `mkstemp' So, is there any portable way to create an std::ofstream to a temp file?

  • File won't save output to file, and prints out a string oddly C++ Linux

    - by Predictability
    I'm trying to make a password code, the user enters a password, then it will save the password to a file in /tmp/ and then it will output the password (For me so I can find bugs). I have included the "string" library, and I set the password type to string, but when I output it, it outputs like this: 0x7fffb55baac0password // <-- thats the password I entered It will output hex (I think), then the password I entered, and it won't save it to the file in /tmp/ I want it to (Or any file in /tmp/). Here's the source code: http://codepad.org/3aamAv7R Thank you for all the help you guys have given me so far.
