More to come. Cheers!

So, how can I do this? It’s simple, you can tweak Chrome with the following startup parameters:

• “…chrome.exe” –disk-cache-dir=<CACHE_DIR> –disk-cache-size=<SIZE_IN_BYTES>

Here is an example, pointing to a ramdisk drive (T:) and allocating a max of 500MB to it (which is nice to be able to control when you’re using ramdisk):

• chrome.exe –disk-cache-dir=T:\ChromeCache –disk-cache-size=524288000

Here is a discussion post about these new parameters for more info:

• Needed Feature: Cache Size/Location

So far this has worked great for me, much better than reallocating the whole home dir using symlinks, junctions and the –user-data-dir parameter . If you still want to do this, follow these examples:

You can now optionally [...] intercept any error message sent back from the server, and perform custom client-side actions as a result [...]. (source)

Well, I disagree with “optionally”. As far as I understand, if you don’t explicitly intercept the error/exception sent back from the server from within an UpdatePanel, your user will get an unfriendly javascript error like this:

So what can you do to fix this? Easy, just add this piece of Javascript code to your Masterpage (or to any page if you don’t have/use a Masterpage):

<%-- This script must be placed after the form declaration (i.e. <form id="form1" runat="server">) --%>
<script type="text/javascript">
    Sys.Application.add_load(AppLoad);

    function AppLoad() {
        Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequest);
    }

    function EndRequest(sender, args) {
        // Check to see if there's an error on this request.
        if (args.get_error() != undefined) {

            var msg = args.get_error().message.replace("Sys.WebForms.PageRequestManagerServerErrorException: ", "");

            // Show the custom error.
            // Here you can be creative and do whatever you want
            // with the exception (i.e. call a modalpopup and show
            // a nicer error window). I will simply use 'alert'
            alert(msg);

            // Let the framework know that the error is handled,
            //  so it doesn't throw the JavaScript alert.
            args.set_errorHandled(true);
        }
    }
</script>

Now you should get error messages like this (javascript alert):

This is exactly how exceptions used to be displayed when thrown inside an UpdatePanel before .NET 3.5.

Note: I do understand the benefits of a the new approach. It gives you flexibility to present the error message any way you want, before your hands where quite tied to this simple Javascript alert window.

As a matter of fact, I’ve implemented a nice ModalPopup and have ensure that only user-friendly messages are actually shown: only messages of a certain type (i.e. UIMessageException) are forwarded to the user without any cleanup/transformation.

One of the most annoying thing about Visual Studio default settings is the fact that the Solution Explorer doesn’t track what files you are currently looking at. Alot of developers thought this was the only way, and had to bear the pain of flicking through the Solution Explorer while scratching their head to figure out ‘where the hell I put this file?’.

There is actually a setting in Visual Studio that does this automatically.

So far, no problems.

A page refresh would usually take up to 3 seconds (localhost) even without changing the source code (so it should be instantaneously, especially now that I’m using a SSD).

It appears that there is some kind of bug on Vista/Windows 7 with DSN and IPv6, but that can be easily fixed. Here are some of the solutions I have found:

1. Recommended Solution – machine wide: uncomment the localhost address in the hosts file (%WINDIR%\System32\drivers\etc\hosts): (source)

# localhost name resolution is handled within DNS itself.

127.0.0.1       localhost

# ::1             localhost

# localhost name resolution is handled within DNS itself.

127.0.0.1       localhost

# ::1             localhost

2. Firefox-only solution: disable IPv6

1. Type about:config in the address bar and press Enter.

2. Scroll down until you find network.dns.disableIPv6.

3. Double-click on it to change its value to true.

4. Restart Firefox.

3. System wide-configuration (option 1): Disable IPv6 Random identifier

netsh interface tcp set global autotuninglevel=disabled

4. System wide-configuration (option 2): Disable IPv6 from Your LAN Interfaces and Connections

1. Launch Vista, click on Start, and then click on Run. Once the Run window appears, type regedit.

2. Once you have accessed the registry, you will add a registry value as follows: (DWORD type) Set to OxFF.

3. The registry is as follows: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents

No, you can’t. Really? Well, you could try to run it with wine… But if you check the latest releases, it’s really not supported… I tried various configurations, wine 1, wine-1.2, iTunes 8.x, iTunes 9.x… Nothing worked!  If you really have enough patience to figure out all of the “fix-me” messages in the wine log, good luck!

Ok, so what can I use instead? What is out there that that truly replaces iTunes?

Well, you will be really surprised by a project called Songbird (www.getsongbird.com). Check this out:

Screenshot of Songbird 1.2

It’s sleek, easy to use and can be customized by tons of plugins…

Installation Instructions for Ubuntu Linux (and similar flavours):

Unfortunately Songbird is not yet available under the “Ubuntu Software Center” or thru Synaptic/Apt-get, so you have basically two options:

1. Download the latest .tar.gz file from the main website (www.getsongbird.com), manually unzip and run the executable file, or,
2. (Recommended Solution): Use this installer (.deb) created by Eric: http://skyzim.com/songbird-1-2-0-installer/

The installation works like a charm, it even creates the proper menu entry under Application -> Sound & Video. Thanks Eric!

Welcome to the Songbird community!

Seriously, I’m talking about at least 10x faster… Check it out:

• Boot time on Ubuntu 9.10 (disregarding BIOS initial checkup time)
  • 7500 rpm HDD:  ~160 sec
  • OCZ Solid Series 60GB  SSD: ~20 sec; (what?! yes, your read correctly)

• Copying Files (ex: typical video of 600 MB)
  • Before, with a “fast” 7500 rpm HDD: a lot… no need to mention, it was pretty lame…
  • OCZ SSD: 12 seconds!

• Firefox Browsing / Overall Impression:
  • Opening tabs, clicking back and other things are now instantaneous with SSD.

Check out this vid to see a guy doing a boot time test on a Ubuntu with SSD: Booting Ubuntu 9 04 with SSD

Even if you’re on a budget,you can start with the entry-level OCZ Solid Series…

Nowadays you can get one for less than $150 bucks… Here is where I got mine:

• http://www.canadacomputers.com/index.php?do=ShowProduct&cmd=pd&pid=020610&cid=HDD.859

Based on some Internet reviews I thought this one would be too slow compared to the other options (i.e. Vertex), but It’s like comparing a Porsche 911 to a Bugatti Veyron, both are extremely faster than my Honda Civic

Happy shopping!

Then every time you change your ASP.NET pages (or any code-behind or reference DLLs) the build will happen much faster because is doing all in memory.

So, how you do this? Simply follow these steps:

1) Make sure you have enough free memory:

Open the usual apps you use (i.e. Visual Studio, Outlook, etc) and check how much free memory you have (Task Manager -> Performance -> Physical Memory -> Available).

So, let’s say you have 500MB free and your total memory physical memory is 2GB (Task Manager -> Performance -> Physical Memory -> Total).  The total I’d recommend allocating for your virtual drive would be half of your free memory, or 250MB.

If you’re short on free memory, try running some cleanup tools like TuneUp Utilities (very good, but paid) or CCleaner (free). Besides that, you can always check what services are running and stop/disable the ones you really don’t need (this is a delicate step, be careful not to stop essential services – use Google to find out what’s essential and what’s not).

2) Install RamDisk

I’m using a free implementation that can be found here. You can follow these steps for a details explanation of this tool and installation instructions.

Make sure you install it and create a drive letter (i.e. “R:”) with the disk size amount calculated in the previous step. If you over-allocate it, your Windows will run out of memory and the whole purpose of this idea will be worthless.

3) Change your default “Temporary ASP.NET Files” folder to your new ram-based drive

Here you have two options. You can do this only for a specific site or for all projects running on your computer. If you have too many sites you may run out of disk space in your ramdisk, so choose your option wisely

3.1) Configuration for a specific website (local settings):

Change your site’s web.config “compilation” property to specify the new path. Below is an example that assumes “R:\ASP_NET_TempFiles\” as the new ram-based folder location:

<system.web>
....
<compilation debug="true" tempDirectory="R:\ASP_NET_TempFiles\">
....
</compilation>
....
</system.web>


3.2) Configuration for all ASP.net websites (global settings):

To implement this globally all you need to do is change your global web.config (which is usually located somewhere like this C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config)and  adjust the compilation properties the same way the local settings (previous example):

<system.web>
....
<compilation debug="true" tempDirectory="R:\ASP_NET_TempFiles\">
....
</compilation>
....
</system.web>

And your done!

Two last tips I can give you is to keep an eye on the usage of your ramdisk folder. If it get’s full, you’ll have to manually delete some old temporary files. The second tip is to watch how your free memory, if it gets too close to it’s total it might indicate the you either have too much programs running or you might have to reduce your ramdisk size.

Happy speed building!
