When using LowCodeUnit, after 'Unpacking Latest' and syncing with GitHub and going to my lowcodeunit.com site, some of the images on my site are not showing up as desired.
Currently LowCodeUnit only supports file paths (and file names) without spaces. Also, entire file paths are case-sensitive (including file extensions). If needed, there is a great free MS tool for batch renaming of files on Windows called PowerRename that you can download here:

We have a website, which allows users to upload documents (word, pdf, PPT, etc.).
We are uploading files to Amazon S3. So, all files will have it's own web URL.
For these uploaded documents, we would like to generate thumbnails. This thumbnail needs to be generated based on it's content (like Google document viewer).
Is there any Service/API, which generates thumbnails of documents by it's URL?
Thanks and Regards,
Ashish Shukla
You could roll your own solution. I'm evaluating 2JPEG and it appears to support 275 formats including Word, Excel, Publisher & Powerpoint files. fCoder recommends running 2JPEG as a scheduled background task. The command line syntax is pretty comprehensive. I don't think it has the ability to process remote AWS files, but you could retain it locally temporarily, generate the thumbnail and then delete the local source file.
Here's a sample snippet to generate a thumbnail for a specific file:
2jpeg.exe -src "c:\files\myfile.docx" -dst "c:\files" -oper Resize size:"100 200" fmode:fit_width -options pages:"1" scansf:no overwrite:yes template:"{Title}_thumb.jpg" silent:yes
You should also take a look at AWS Lambda. In fact, this presentation from the AWS re:Invent 2014 conference shows a live example of using Lambda to generate thumbnail images. This solution will be very reliable, and very cost-effective, but has the downside that you'll be responsible for maintaining the code, or debugging issues.
In my chrome app, I am using HTML5 file system to save the pdf files to sand box.Downloading is working fine.But how do i access that downloaded file path? I want to give that path as webview source.
The best way, if it works, would be to use a filesystem URL. To get this use FileEntry.toURL
These don't work on external files (i.e. files that come from chrome.fileSystem.chooseEntry and are outside the app's sandbox) but should work for files in the app's sandbox.
Note, I am referring to filesystem:// urls not file://urls, which won't work as Marc Rochkind has pointed out in his answer.
Disclaimer: I haven't tested this, but I believe it should work.
You need to get the contents of the PDF into a data URL. See my answer to this question:
Download external pdf files to chrome packaged app's file system
I've taken on the webmaster role for a website that uses DNN version 07.02.02. Most of the links to my pdf files are broken. They pdfs were in a folder called "/pdfs" now they're in a new folder "/docs/pdfs "
A few quick things:
I only have ftp access to the web site files. No access to web.config so rewrite rules are out.
I don't want to copy the old files back to "/pdfs" because it would mean managing two different pdf copies (there are over 500 pdfs).
Using file directories with a .pdf extension then add an index.asp file with a redirect i.e. "/pdfs/file_1001.pdf/index.asp" led to an error page because there's an override which doesn't allow site directory pages exposed.
Using a DNN module where I'd have to enter 500 files to redirect seems redundant when I only want to move a directory.
Any solutions to try?
In DNN if you have HOST level access you can modify Config files through the Host/Configuration manager page.
There you could modify the web.config file.
You might also look at the siteurls.config file (also accessible there) in which you could define some URL rules, might be as easy as
<RewriterRule>
<LookFor>/pdf/(.*)</LookFor>
<SendTo>/docs/pdf/$1</SendTo>
</RewriterRule>
The above rule is completely untested, not positive if it will do what you need or not.
I did a little more testing, and it looks like this won't work out of the box as a default setting that tells it to NOT rewrite PDF files, but I can't find the source code for that currently.
I am currently trying to download a small binary file from the web, in order to upload that to another website, both using the API.
Previous versions seemed to have the "file" API module for such purposes, but I can't see anything similar as of the latest (1.14).
The file to be downloaded would be saved in some form of cache (browser cache, preferably), its path stored somewhere, to be then uploaded to another URL via POST.
How would I go about it, when the process should happen completely in the background?
I checked out the how to download a file page, but can't figure out where to download.
Is there a variable URI for the "Downloads" directory, and does a regular Add-On has write privileges in it?.
This is important, because the add-on must be able to function properly on various platforms.
You can use the pref, browser.download.lastDir, which should work for windows/mac as it will be saved in the OS format. However the pref may not always be set if the person has never downloaded anything before. In that case you'll have to build the directory yourself.
var dir = require("sdk/preferences/service").get('browser.download.lastDir');
To build the directory yourself you're going to have to go a little deeper. Check this article on MDN about File I/O which has examples. The DfltDwnld key should give you the directory you want.
Your add-on will have write permissions to everything Firefox has write permission to.
I would like a better workflow for debugging uploaded SCOs. As things are, I must edit a file in the activity, repackage, upload, and test. Often, I just need to change a single line of code. It would be VERY nice to be able to edit that file, that line of code, on the server. So far, all I've found is that Moodle manages the files, so it seems impractical to locate and decipher the renamed files after upload.
Is there a way to configure Moodle so that it doesn't rename and relocated files in SCOs upon extraction? Actually, I'm open to any suggestions on the best, fastest workflow for debugging SCOs.
Problem background
Since Moodle 2.0, files are no longer stored on server in the conventional /this/is/the/path/to/my.file way. Instead, files are rehashed and stored in Repositories (i.e. spread all over the moodledata folder as a collection of seemingly random data). This increases security and cross-OS compatibility but complicates stuff for people who would like to simply upload a SCORM zip package via FTP. Here's more information on file handling in Moodle 2.0
Path to the soluton
Let's locate the file you want to update, then update it.
Run phpmyadmin, go to mdl_files table, find your file by name in the filename field (let's say it's portrait.jpg)
Look at the contenthash field, it'll look like abcde1234567890. This means your file is stored in moodledata/filedir/ab/cd/ folder under the name abcde1234567890.
Rename the updated portrait.jpg to abcde1234567890, upload and overwrite.
Go back to phpmyadmin and update the filesize field in record for portrait.jpg with the size of the updated file.
Obviously, this process can be automated. You'll have to write a script that allows you to upload a file, then it'll search for that file in mdl_files, save it to the correct folder and update all fields accordingly.
Alternative idea
Enable external package type (and also enable 'Update on every launch'). Go to Site administration / Plugins / Activities / SCORM and check the box down below. Now you'll be able to launch SCORM packages directly from another server, so Moodle won't mess with it. Of course, you can run in other (probably cross-domain related) problems.
Sergey's answer is very good, with one caveat:
In his example with the contenthash of abcde1234567890, the file is stored in the moodledata/filedir/ab/cd/ folder under the name abcde1234567890. Moodle uses the full contenthash to name the file.
