my area is building a new transit line, and I'd like to "add" it to trip planners for comparison's sake. Before I dive into Mapbox and reinvent the wheel, is there any way to add or reference a GTFS file from within an existing app, say, Google Transit, without adding it to the service?
Thanks for any help, and sorry if this is covered somewhere; I swear I didn't see it.
Import existing GTFS file into suitable editor. For example this one
Add new "theoretical" transit line. Save it.
Export new data to new GTFS file
Use schedule viewer to view it.
Schedule Viewer is a Python program for viewing the contents of a GTFS feed on a map. It's a diagnostic program intended for those creating a feed

I expose my problem: I have recently started using CortexDB, a NoSQL software to database analysis. I have read the (poor) documentation on https://docs.cortex-ag.com/en/CortexDB/CortexDB/, and purchased a free license to evaluate the operation of the program. As the documentation is unclear I would have some questions to ask you:
1) How do I create a database?
2) how can I import a database contained in an excel file (.csv)?
3) how do I create charts or analyzes regarding the data entered?
Thanks
because the question is very old I hope I can still help you.
First of all: you should download the latest release of the free version (simple registration and download)
if you downloaded the free version you got the server and two databases. A server process handles one database. For a second database you have to start a second server (different port of course). If you start the free version you should have an empty database (or the filled and configured demo db). If you want to create a complete new one without any predefined configuration, you have to start the server process with the command line and the parameter -n (ctxserver64 -n). If you did that you have to configure everything by hand with the tool ‘remote admin’.
the question is not clear for me. Do you mean how to import a csv file into a CortexDB or do you mean how to import the database content into an excel file?
If you want to import the csv file into a CortxDB, the easiest way is to use the tool CortexImplex. It’s completely explained in the online docs (https://docs.cortex-ag.com/en/CortexImplex/CortexImplex-Basics/)
If you want to export datasets as csv file the only thing you have to do is to configure a list in the CortexUniplex as a view for your datasets and export them as csv (you find the export function in the list menu).
I would do the charting with d3j. For this you can use the so called ‘DataService’ of the CortexUniplex. It’s a kind of an API for posting requests and getting JSON objects. If you have a completely configured UniPlex you can use all of your configuration as json objects for other apps (for example charts or an individual application).
The full version has a simple dashboard inside of the CortexUniplex. Maybe the vendor offers it in the free free version.
By the way: it’s always good to write an email to the info address. Because this database is not so famous and known, the guys are very helpful. Or contact them via twitter or other channels (see at the bottom of the cort ex-ag.com webpage).
The title says it all. I need to create a form that the user fills in and on submit, I want the data to go to a database and a PDF to a directory on the server.
I don't think AngularJS can do all of these things, can it? I'm very new to programming -- trying to crossover from HTML/CSS/JS to more in-depth projects.
Can anyone please suggest the best course for this? What language for the form, writing to the DB and generating a PDF? I can do the rest of the research and build it out once I have some direction.
How would you go about achieving this?
Thanks!
Ugh. I forgot to mention that PHP is not an option. Is there another way?
All you need is to apply the paradigm Client / Server.
With angular.js you can build the client software for handling the form but this is not necessary...
With a single script php you can generate the page with the form and handling the incoming data.
You can use a standard relational database like mysql for storing it and, about the pdf, take a look here
I have a site that I'm looking to transfer to Volusion. Importing tabled content into Volusion's a breeze, it's getting it tabled that's an issue. The old site has no real ability to export, nor do I know how to get at it's database. I'm thinking there must be some sort of script I can write to take the content from the frontend and download it in some sort of list that I can put into a CSV, and put into Volusion.

Any suggestions? I'm hoping to get in the image directory as well and download all them for upload to the new site.
You are going to need at the very least a file with product code, product name, weight and price.
Looking at the URL you provided it doesn't appear that the products their follow any type of orderly structure where you can target the images folder or products based on a known piece of information like a products code. Unless the back-end has some type of product export function you may have no choice but to recreate it from scratch.
I don't know if you solved this yet or not, but I would suggest scraping the data providing you have the information on the old site currently. This can be done easily using vbscript and excel, or if you aren't very savvy at coding you could look at a piece of software called mozenda. There are a whole variety of methods that can be used to scrape data, all of them pretty easy to learn with a bit of research. Basically you write a script that will crawl your dom and extract the data (to xml works best in my experience)
Hope this helps.
I'm not guru in DBA, so I'll try explain what I want in terms I imagine it.
I have Oracle DB with network devices. each device has ports which has parent device/port
I want some tool which will automaticaly create visual map of this device relations.
Will create "Network Map" based on this relations.
It's would be better if this tool will have some output ready for web publishing, or web based tool from the begging. Also if it will automatically update "picture" as soon as I add new relation/object
From far it looks something like Gource http://youtu.be/E5xPMW5fg48
But not exactly what i need
Hope to get some suggestion.
Thanks in advance!
UPD: found another tool: Gephi
You could try graphviz. It was created specifically for visualising large graphs of network nodes.
It's not out of the box; you'll have to write some code that:
Reads data on the devices & their relationships
Creates the graphviz input file
generates the diagram by calling the graphviz binary.
There are many ways to do that. One of the easiest is to use python with the pydot library.
Note that graphviz generates static images (jpeg / tiff etc.) so you'd have to regenerate on demand.
There are more interactive toolkits available, e.g. protovis / infovis. Both are javascript based and render directly in the browser.

I am interested in creating a video databse. My goal is to have a folder where my videos will be kept and each time I copy/delete a video the website that presents them should be updated to. the problem is I have no idea how to approach it.
Should I..
Use Sql and store a reference to each video location?
Have a script that checks all the time if new changes happen in that folder?
A package like joomla?
I am using ubuntu btw. I already have a simple html5 page, and I am presenting the videos using html5 video.
It depends on the size and the performance you want.
1.Way : use php to scan the folder and generate links on the fly
2.way : Use a database to store the file names and retrieve the names from the database and generate urls
pros and cons.
simple to implement , no changes in upload or download script. no database required.
You need have a database , little coding required for upload and also while genrating a page
You should make a db (format does not matter) and storing in it only file names of videos: the videos would be stored on hard drive.
Any operation on the web site will pass first on db for insert/update/delete videos records and then (maybe in a transaction context) on the file system.
This would be the standard approach to your question.
