Killing zombie Google Chrome processes

This article is also available on the Microsoft TechNet Wiki.

When using the Google Chrome browser with of mix of normal and incognito windows, long-running sessions with multiple tabs can sometimes chew up a lot of memory. It certainly does not help either that Google Chrome spawns 10+ processes for any given browsing session. So when it comes time to close these browsing sessions it is not uncommon for Chrome to leave behind several zombie processes in the Windows Task Manager.


To terminate these remaining processes you can right-click them in the Task Manager and select End task. However, there is a faster way using either a PowerShell command or Windows Batch (.bat) file. Let’s examine both ways.


Within PowerShell, there is the Stop-Process Cmdlet. This will allow you to terminate all processes in one command. You can kill the process either by process name (minus the file extension) or by process ID. Since we want to end all Chrome processes, we would use the -processname parameter combined with the process name:

Stop-Process -processname Chrome

You can enter this command into the PowerShell window or save it to a PowerShell script (.ps1) file that you can run from the Windows PowerShell ISE.

Batch File

Another, simpler, way is to create a Batch (.bat) file. A batch file is a script used in Windows. It lists commands that can be run using the command line interpreter when the file is either called from the Command Prompt or double-clicked.

To stop processes, we can execute the taskkill command:

taskkill /F /IM chrome.exe /T

This command will use these parameters:

  • /F: Identifies that process(es) be forcefully killed.
  • /IM: Identifies the image name of the process to be killed
  • /T: Kills all child processes along with the parent process, commonly known as a tree kill
    If we combine this with a For Loop we can see the number of processes being terminated:


When run, the script will pause to display all terminated processes including the associated process ID (PID). As well, the total number of Google Chrome processes removed is also listed.


In this article, we saw how we can use both a PowerShell command and a Batch file to terminate hanging or zombie Google Chrome processes. Try either method if you have problems with Chrome processes remaining on your machine after all sessions are closed.

10 tips on submitting a conference session proposal

Conférence NWX2012

CC Image courtesy zigazou76 on Flickr

I have been seeing a lot of calls for speakers to submit their abstracts to various conferences lately. This got me wondering what it takes to get a session proposal accepted. Is it that the session content is cutting edge or is there something more to it than that? So I scoured the web for the best tips and compiled them here.

Your first question though might be where I do I learn about conventions looking for speakers? Well, since I work in the .NET stack I am only tracking conferences looking for speakers on .NET or Microsoft products. To find these I closely monitor Speak.NET. This is a group that finds and rebroadcasts calls for speakers on all things Microsoft. You can follow Speak.NET through Twitter @SpeakNET or through their Google group SPEAK.NET. Note though that to access this group you must sign up to be a member through your Google account. If you are new to Google Groups you can get more information through their Support Page. Finally, many of the posts are duplicated between the Twitter feed and the Google group so checking in with one or the other should be sufficient to keep you abreast of all the current announcements.

So, now, here is my list of what I found makes for a good conference proposal:

Read the speaker guidelines

A sure-fire way to not get your proposal accepted is to do something they have asked you not to do. Take five minutes to read the instructions they wrote for all submissions, including yours.

Get it in early

Most symposiums announce their call for speakers weeks before they open the floodgates for proposals. This should give you plenty of time to think about whether you want to even to give a talk at that particular seminar and if so to come up with a good topic. By submitting early you are showing the conference organizers that you want to be a part of the speaking line-up. As well, some conferences assign spots as the proposals come in so waiting to the end means a smaller chance of acceptance.

However, even if you missed the initial call for speakers most conferences give people about two weeks to get a submission in. That being said try not wait until the final day as that could leave a bad impression with the people selecting the speakers.

Having a good title

You want to make sure the title is descriptive enough to grab everyone’s attention. A title like “LightSwitch Development 101” is not as exciting as a title that says “Develop a complete LightSwitch app in 20 minutes”. You also want to make sure that any non-native English speaking attendees can understand your title and session abstract easily enough.

Make sure you can deliver on what you promise

Regarding the point above, if you say you can deliver a LightSwitch application in 20 minutes make sure you can or you will lose the audience. They will then discount the rest of your presentation or worse, tell others not attend any future presentations which could be disastrous if you have several planned for the same conference.

Having the right amount of material for your allotted time

You want to make sure you can cover your topic in the amount of time you have been given. If you give a high-level overview you may find you don’t have enough material. On the other hand if you try to cover every aspect of your topic you might find you are rushing through your slides with only five minutes left. Make sure you can go at a decent pace with some time left for questions at the end.

Don’t do a sales pitch

If you are presenting a topic that relies on a certain technology then make sure it is not a sales pitch. Tell the organizers that you are including the product to assist in your talk but not to be the focus of it.

And don’t think about doing a bait and switch either. Meaning don’t tell the organizers that you will not be focusing on the product and then once it is accepted make your entire presentation an overt sales pitch. You will only burn your reputation for future talks.

Having a good session description

A well-written session description has two goals – 1) entice the conference organizers into accepting your abstract, and 2) get attendees into the seats (since most conferences will use your submitted description within their promotional materials). To do this you want to show you are passionate about the topic you are presenting. If you have a passion for teaching the technology then people will want to hear what you have to say.

You must give people a reason to come and hear you speak instead of one of the other sessions you are competing with in your time slot. What you want to do is tell people how your talk will benefit them in their day-to-day work and to give them information they can use immediately. Returning to the LightSwitch example above you could add a statement like “Developing a simple CRUD application with LightSwitch will reduce development times by 50%!” People reading that can see an instant benefit. As I said before though make sure you can back up your claims.

Also, try to be very specific in what your session is going to cover. Do not think you can submit a high-level overview of the topic as your description. Conference selection committees want to know specifics about what you plan to talk about. Are you doing a case study, a live-coding demo, delving into a certain area only? Tell them this in your pitch.

Finally, try to make the description concise. Eliminate any unneeded words and sentences. This makes it easier for the conference organizers to remember your abstract when it comes to making their selections. It also helps attendees make their choices as they can quickly understand what your talk is about.

Complete the entire abstract portion of the form

The organizers have created the form specifically to gather certain types of information they will need to make their choices. Leaving portions of it blank shows them that you did not take the process seriously and this can cast your proposal in a negative light.

Make sure you fill out your biographical information in full

Give the conference planning committee every pertinent detail about yourself that you can. Write a compelling bio and tell them what makes you qualified to speak on the topic. This is especially important if you are not a well-known speaker or if you are travelling to a conference outside of your normal speaking circles. It also allows you to differentiate yourself from others speakers.

If the form includes areas for various social media accounts like Twitter and LinkedIn then fill them in. If not then include them in your bio. You want to demonstrate to attendees that you are open to continuing the discussion after your presentation is over.

As well, make sure you have links to your developer’s blog and your previous presentation videos including any YouTube screencasts you may have done. If you do not have a developer’s blog read my article on how Creating a developer’s blog can benefit you. If you have done presentations in the past push your slide decks to SlideShare and mention those links to the selection committee. Finally, you can also include any URLs to sites that contain information you are planning to use in your presentation as this shows that you have given your topic some in-depth thought.

Check over your session abstracts and bio thoroughly for errors

When submitting your session proposals you are competing against everyone else for a spot on the speaker’s list. The conference organizers want to know you are not going to waste a spot by giving a shoddy presentation. So attention to detail here is crucial. Make sure you double check your entire submission over several times for grammatical and spelling mistakes. Better yet have a friend read it over to make sure that the topic sounds compelling and that your submission is tip top.

So these are the top 10 items I found in my research. If you are a conference organizer or a seasoned speaker and you have other useful tips then please leave a comment below as I would love to read them.

The many benefits of speaking at conferences

Using Dropbox, Site44 and Google Drive to create a quick registration site

I recently came across a new company called Site44 and they have come up with a very neat product. By connecting your existing Dropbox account their site acts as a website hosting service for your HTML pages. This means that in mere seconds you could have a functioning website up and running that you can modify by simply overwriting your existing HTML file with a modified one that incorporates your new changes.

In this blog post I will delve into all three technologies and show how we can link them easily to create a quick user registration site for any community event or contest you might be running. By harnessing the power of Google and Site44 you can give your organization a free online website simply and easily. For less technical people you could even choose to create your webpage with Microsoft Word and save it as an .htm file. For this demonstration though I will code a simple site using Notepad++ and I will also include some CSS, JavaScript and jQuery elements to show you the power of Site44.


Dropbox was founded in 2007 and it is a free cloud storage file system. Much like Microsoft’s SkyDrive or Google Drive you can upload numerous types of files to the Dropbox server so that they are accessible to your account anywhere is the world. It comes with 2GB of space initially. You can synchronize your files by using their web interface to upload and download items or you can install their program onto your machine which will create a Dropbox folder structure for you. You can then drag files into this folder and Dropbox will sync your items for you.

Dropbox allows both folder and file sharing with anyone, even if they are not Dropbox users. You can choose to make folders public or private and then you can share links to these items. For the purposes of this demonstration you will need a Dropbox account. You can create a Dropbox account here. (Full disclosure: this is my referral link).


The tag line for Site44 is “absurdly simple web hosting.” In essence the company’s service turns Dropbox folders into websites. Having played with the site for a little bit I can honestly say that their tag line lives up to its name. It was easy to get started and I had my test site loaded within minutes. In fact it took me longer to code the HTML page than it did to prep the site. As you will see in the demo below the process could not simpler!

It is free to use Site44 and with the unpaid account you get five websites and a data transfer limit for all sites of 100MB/month. A word of warning from the Site44 team though. The service is still in beta and so they have posted this disclaimer: “Although it has undergone significant testing and is not expected to change significantly prior to general release, the use of Site44 is not recommend for production environments. You are encouraged to use Site44 for testing and non-critical purposes only.”

Due to the bandwidth restrictions on the free Site44 account you will not want to stress the system out by placing large files or pages with heavy content on your site as you might run the risk of maxing out your limit. As Site44 says their service is for lighter loads and is an excellent way to debug some of your code. You could also use the service to house any non-sensitive project proposals or mock-ups that you might want to demonstrate to clients.

Finally, Site44 only supports client-side scripting which includes JavaScript. Any server-side scripting of PHP or ASP.NET pages is not allowed. Placing such pages on your site will not fail but will simply show the page code to the viewer.

Google Drive

Google Drive was released in April 2012 and it is similar to Dropbox in that it is a free cloud-based file storage system. Like SkyDrive and Dropbox it also provides a synchronization service from your computer to their servers. They offer an initial 5GB of space. Google Drive is an extension of Google Docs which is a set of tools that allow you to create and collaborate online to generate documents, spreadsheets, presentations, etc.. Files created in Google Docs get housed in Google Drive automatically. They can then be downloaded to your personal computer for editing. Both of these features are accessible to anyone with a Google or Gmail account.


Let’s first create the HTML page that will house an introduction, some instructions and the link to our Google Docs file. When it is rendered it will appear as a form on the page so people can enter their information. I will also include on this page some calls to CSS, JavaScript and jQuery to demonstrate that all three are supported on Site44. (Note: all of the example code used in this demonstration will be available for download at the end of this post.)

Listed below is the HTML for my site. As you can see it is pretty vanilla code that invites people to register for  a fictitious Windows 8 workshop that I am hosting. If you scan the code you will see I reference CSS, JavaScript and jQuery.

    <title>Beginning Windows 8 Workshop</title> 
    <link href="Site.css" rel="stylesheet" type="text/css" /> 
    <script src=""></script>

    <script type="text/javascript"> 
            function () { 
                    .animate({ width: '+=150px' }, 2000) 
                    .animate({ width: '-=150px' }, 2000) 

    <script type="text/javascript"> 
        function ShowDate() { 
            var mydate = new Date(); 
            var year = mydate.getYear(); 
            if (year < 1000) { 
                year += 1900 
            var day = mydate.getDay(); 
            var month = mydate.getMonth(); 
            var daym = mydate.getDate(); 
            if (daym < 10) { 
                daym = "0" + daym; 
            var montharray = new Array("January", "February", "March", "April", "May", "June", 
                "July", "August", "September", "October", "November", "December"); 
            document.write(montharray[month] + " " + daym + ", " + year) 
        <script type="text/javascript">ShowDate()</script> 
    <div id="animate">

        Event starts at 6 pm 
        Seating is limited so act fast! 
        Please register below for my Windows 8 Workshop for beginners: 

I am using JavaScript to show the current date on the page and jQuery to animate the Windows 8 logo upon $(document).ready. I have placed both of these client-side scripting items on the page to show that they can work on Site44 and that they can combined if needed. If you find though that one item is not responding you might need to use jQuery.noConflict to return control of the $ back to the other library.

The rendered HTML page will look like this:


This page is almost done but I need to add in my Google document. We will build this now to complete the site.

To create our registration form navigate to the Google Drive website. Click the red Create button on the site and choose Form. You will then get a template similar to this in which two fields are already created:

Empty Form

We can then edit this form to add a title and as many sections as needed. You can also select various input methods including text, checkbox and radio button under Question Type. Fields can also be marked as required to ensure a successful submission. To add subsequent sections click the Add Item button in the upper left. For my site I wish to collect the following items from each registrant:

  • First Name
  • Last Name
  • Email
  • Phone Number
  • Company
  • Poll – Is your company planning to switch to Windows 8?

The finished form will then look something like this:

Finished Form

The title you place on your Form page is the subsequent title of the file. If you close the form editor and return to your Google Drive page you will see the registration form you created in your list of documents. Clicking on the form will take you to the responses page.

Form Spreadsheet

This page is effectively an Excel spreadsheet. Notice how each field on your form is a column on the sheet. Every registration will be contained in a single record in this document. Once I have closed registration for this event I can then go to File | Download as to export all the responses to any file type listed there. If I choose something like .xls I could then use this spreadsheet to track attendance at my event. To edit the form or add additional fields just click Form | Edit form. Use this Help Center for more information on Google Docs.

Now that our Google form is ready we can embed the form’s link in our HTML page. This will make the form render on our registration page so that prospective registrants can start signing up for my course. To embed a Google document you need to find the key to the document. To find the link to our form click Form | Embed this form in a webpage. A dialog box will appear with an IFRAME link. Copy this link and paste it into your HTML page wherever you want your form to appear. In my HTML page I am pasting it at the bottom as the last paragraph. The IFRAME’s source attribute looks like this:

width="760" height="689" frameborder="0" marginheight="0" marginwidth="0"

Your form will appear at the bottom of the page like this:

HTML Page With Form

Notice though the title we gave the form appears on the page. As well, the default width has pushed the form off to the left and is out of skew with the centered text on my page. I also get a vertical scroll bar. I will adjust the width to be 400px and I will append &ttl=0 to the src attribute of the IFRAME which will hide my form’s title on the page. (See more examples here of how else to modify Google Docs.)

My IFRAME source attribute now looks like this:

width="400" height="689" frameborder="0" marginheight="0" marginwidth="0"

And my page looks like this:

HTML Page With Form Modified

The next step we need to do is sign up of for Site44. To do this we will go to Make sure you have created and are logged into you Dropbox account. On the Site44 page you will see a button called “Sign in with Dropbox to get started.” This will allow Site44 to create a trusted link with your Dropbox account. Note though that you are NOT giving them access to your entire Dropbox contents. They will only create and share one folder that is necessary to build your websites.

Once the link is made you will see a page called Your Websites. Click the Create a new website button to start building your first site. A dialog box will appear and on this page you can create a free page or you can use a custom domain if you own one. We will choose a free site for this demo. I will use the site name I did not include the words “Beginner” to my site name so as to keep the webpage generic. This way if I want to add more advanced workshops later on I can keep my same site but just update my registration page as needed.

Once the site is created Site44 takes me to my new webpage. The page contains some default text including the URL of the site and where it is housed on Dropbox.

Website Default Page

If we now move to our Dropbox account we can see that Site44 has created a new root folder called Apps. If we drill down into this folder you will a site44 folder and then a folder for your new webpage. Within this page there will be an index.html file. This is the default page shown above. You can edit this page or remove it all together.

Now depending on if you have installed Dropbox onto your computer or not (if not you can use the web interface) upload your HTML page and any resource files you might need to run your site. If your site is large enough you can create subfolders to house your images or style sheets if you want but just keep in mind that you will also need to update your source paths in your web page. My site folder now looks like this:

Dropbox Folder

When we return to we get a 404 error as I have removed the index.html file. I could use a landing page to redirect users but for this demo we can just go right to our new page at We will now see the following:

Complete Website

And if I register myself on the site my Google Docs form responses page will display my registration like this:

Form Spreadsheet With Entry

So, in this tutorial we saw how we could use Dropbox, and Google Docs/Google Drive to create a quick registration site. We were able to incorporate both JavaScript and jQuery into the site as well as CSS. Let me know what other creative uses you can think of for using Site44 by leaving a comment below.
