Trying to demonstrate a web worker API to my Web Development students and I wanted to make the process of changing a color image to grayscale in the worker. I know it doesn't take much processing but I'm just using it as an example. I have the grayscale working fine when it's not separated out into a websworker ( jvalencia.ceiwd.com/contoso/badge1.html ) but when I put the code into a webworker the progress bar works but the grayscale image doesn't work--the color image is loaded. ( jvalencia.ceiwd.com/contoso/badge.html )  What am I missing?

WORKING (With no Web Worker):

function showImage(file) {
      reader = new FileReader();
      reader.onload = function (event) {
            console.log(event.target)


            
            if (holder.getContext !== undefined) {
                  var context = holder.getContext('2d');
                  var destX = 0;
                  var destY = 0;
                  var imageObj = new Image();
                  
                  imageObj.onload = function() {
                        context.drawImage(imageObj, destX, destY, holder.width, holder.height);


                        var imgData = context.getImageData(0, 0, holder.width, holder.height); //get image from badge
                        var pixels = imgData.data
                        console.log(pixels);

                        for (var i = 0, n = pixels.length; i < n; i += 4) {
                            var grayscale = pixels[i] * .3 + pixels[i+1] * .59 + pixels[i+2] * .11;
                            pixels[i  ] = grayscale;        // red
                                 pixels[i+1] = grayscale;        // green
                            pixels[i+2] = grayscale;        // blue
                            //pixels[i+3]              is alpha

                            var…

I have to draft a guideline for systems that interface with a CII system & need inputs:
currently, the interfaces concerned are limited to 3 types only:

1. files transfer
============
I can only think that the generally practices ie:
 a) encryption of data in transit (eg: using sftp instead of ftp/mapping a drive or NFS)
 b) encryption of data at rest if it's sensitive (tampered with)

2. API
=====
how do we secure these (in particular APIs using microServices)??
I've heard of API needs to be certified so before requesting for it, need to be certain
else applications developers may question its relevance/usefulness

3. DBLink
========
Those sqlconnect  esp Oracle links to extract / update data.
Will need to define if the non-CII system is
   a) updating into CII, will have to be extra stringent but how?
   b) extracting from CII, just encrypting the sql calls
 

Oracle databases, weblogic are involved in the critical systems
while the less-critical systems may be Windows, Linux on
various apps (including mobile apps).

Editing thread to add Oracle as it relates to DBLink.

We have setup a Windows 2012R2 RDS with Web apps. When we publish the apps they are not showing up in the work place. In the properties of the published app the Remote App program folder has nothing in the drop down menu. I have removed the Collection and created a new one with the same results. Any suggestions on resolving this issue would be greatly appreciated. TIA

i have multiple ms accounts and I always use visual studio community 2015 IDE as well as TFS Online.
My issue is: sometime MS Visual Studio keeps remember my first ms account for e.g. client A. When I try to sign out and sign in another MS account for client B - TFS online
It does not allow me to connect client B - TFS online. Seem like the cache issue but have no idea how to fix it

I manage a bunch of websites that mostly use Coldfusion. Each website is located in its own directory on the server and they all use the same version of the code and they each have their own database. I am trying to figure out what is the best way to update all of the sites when I make a change to the code. Right now I have created a directory on the server that contains the changed files and then I use directoryCopy to copy over the new files. My code looks something like the following:

<cfset temp = directoryCopy("_UpgradeCode","website_to_update_directory/",true,"*.*")>

Select all Open in new window

One issue that I have is that I don't know if there were any problems copying over the code.

Can anyone suggest a better way to update websites? I am hoping that this can be done in an automated way so that I can just call a function or something and then it automatically updates all of the sites. I have created a list of sites to update that can be passed to the function.

Thank you for any help that you can provide about this.

I need to change a gridview datasource/connectionstring based on session parameter/login.

Just a little background, we have an in-house software that generates an .mdb database file and then uploads it to our hosted database-driven website via FTP. Each of our customers get their own .mdb file and a login to the website. The website is designed to show only their assigned .mdb. But the website has limited capabilities.

So I was tasked to update the website and found out that it uses .asp, but I am not well versed in VB script and found that creating an .aspx web application is easier.

Now I'm developing a web application in Visual Studio that utilizes the same database but with added features such as sorting, paging, and filtering based on keyword searches.

I've finished creating the login part (with sessions), and I've been able to create a page that displays data on a gridview. My problem now is that I don't really know how to change the gridview datasource based on login/session.

By the way, the database for login information is also an .mdb and is also uploaded by our in-house software. If we need to add new users, we use the in-house software to update the .mdb and then upload it to the website. There are 3 columns in the database table, username, password, and client code. I would like to use the client code to pull the correct database file because each of the database files contain a specific client code already.

Please assist. Thanks!

I am trying to put together some pertinent questions in regards to our corporate website, in terms of technology, hosting, support, roles & responsibilities etc. This is to assist in an independent review of the website by a 3rd party from both accessibility, performance, security etc. Can you suggest some relevant 'fact finding' questions that if you needed to understand the setup of a website, and its hosting, and all the various technology components used to develop and maintain the site. It is not something I have ever had responsibility for, so having some queries in order to get a better understanding would be most useful.

Hi , I need an advise .
Do anybody know , what is the most popular architecture for .Net WEB application?
I mean before 2008 I use
ASP.NET 3.5  + Adjust  Toolkit cl [b]- front end ( view)
Typed DataSet  + Busies Logic CS classes middle tier ( model)
Public generic  cs class injected into Code Behind of every page was responsible  for binding / back binding
ASP.NET controls  to Typed Dataset  ( controles)
Public generic  cs class was responsible  to fill out Typed Datset data from SQL Server ( DAL)
Back end is always was SQL Server
Export / Import of the data was always via WEB Services  or sql jobs  which were run  from the last data received identity  (for performance point)
Right now so many Framework.

Do you   how use them  the most optimal way?
I mean what is the best way  to  implement
1)Most  efficient front end
2) Middle Tier with Business logic
3) Data  Access Layer
4) Data Exchange (Export/ Import) with   different clients
 
Please advice

I'm using a normal windows 10 desktop pc.

I tried the instructions from the link above in this section

HOW TO SAVE PHOTOS FROM INSTAGRAM IN WINDOWS AND MACOS

It worked fine using downloadgram except for one thing, it only saves the first picture in the post.

Sometimes an instagram post has more than 1 pictures

To view the other pictures i just click the right arrows that show above the picture.

How do i download the other pictures?
With the method above It only lets me download the first picture.
So if a instagram post has 4 pictures in the post, how do I download the 2nd picture? or all 4 pictures?
