Running Windows 8 on local virtual machine

by Dmitry Kirsanov 21. September 2011 11:06

Just to repeat what I’ve said in my Twitter recently – now you have the ability to run Windows 8 Developer Preview on your VMWare Workstation. One week ago VMWare released Workstation 8.0, which doesn’t crash and indeed works quite well with Windows 8. Microsoft Virtual PC, as well as earlier versions of VMWare, still crashes.

After installation, you may notice that Start menu is changed by what is called Metro. If you prefer the “old” style Windows 7 menu, you can switch to that by switching one setting in Registry Editor.

In case you are using mouse, rightclick the taskbar, choose Task Manager, go to File and choose New Task. Now type regedit and click OK.

In Registry Editor, navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
There will be setting named RPEnabled. Doubleclick it and change it’s value from 1 to 0.

Now enjoy your start menu.

Equation

12 hours + 3 bottles of beer = new ASP.NET website with bright future.

That’s for database, WCF back-end and what they call “architecture”. GUI will take couple more hours, but not today. Will show that project this week. However, although it’s purely not commercial, I wonder what it takes from a good developer with dedication to establish something he would be proud of.

Sneak Peek into Windows 8 GUI

by Dmitry Kirsanov 14. September 2011 17:29

Just wanted to show the most interesting part for system administrators about changes in most frequently used functionality. Task Manager and file copy / delete operations. As you may see, Task Manager became much more functional and file operations more ordered.

Although the ribbon in Explorer is not shown, it is here and definitely adds to user experience, but can be removed… When it doesn’t :)

Windows 8 GUI sneak peek, switch to Full Screen for better view.

Visual Studio 2010 Test Manager Overview

by Dmitry Kirsanov 14. September 2011 16:17

A little demo about how to use Test Manager from Visual Studio 2010 Test Professional / Team Foundation Server.

This one is the first of a series and doesn't either have or require any sound. Ideal for those who are using it as a reference during the work with real environment.

Play it full-screen for a “better experience”

This is a typical lab from Microsoft Official Curriculum. Don’t know how you, but I usually enjoy seeing things done as much as doing them, whether it is a lab or a computer game.

Windows 8 Developer Preview revealed

by Dmitry Kirsanov 14. September 2011 15:00

This night MIcrosoft opened the prototype of their brand new OS and this build was named “Developer Preview”. Aimed mainly at software developers, it has a copy of not yet released Visual Studio 11, using which you can create software for that same Windows 8.

The only downside of this release is that you couldn’t install it on either VMWare workstation or Windows Virtual PC – it could only be installed on either physical or Hyper-V machine. I installed it on both.

First fascinating things about new OS is drastic change in user experience. I don’t even mean the new Metro and effects, but also much reworked file copying routine and Task Manager. The latter became as useful as it never been.

Although scheduled release date is not yet revealed, and most likely will be somewhere in Autumn of 2012, chances are you can grab a copy of ISOs at MSDN.

Windows Live is alive

by Dmitry Kirsanov 11. September 2011 19:10

Do you remember such thing as Outlook Express? A lightweight e-mail client from Microsoft which was the part of operating system since the stone age. It was separated from Windows for good, so unlike in Windows XP, we don’t have to cut it from the distribution DVD anymore. However, once separating some applications from the system, Microsoft added a few more tools to the Live family.

One of them is the one I am using at this particular moment – Windows Live Writer. The thing looks like a Microsoft Office 2010 product, something similar to FrontPage, but it’s about blogging. Whatever platform you are using for your blog, it can connect to it and you can use this wonderful editor without ever having to log into your blog. Styles, working with resources - everything is here. And it’s free.

Another one is irreplaceable for me and it is called Live Mesh. Once you’ve got your free 5Gb space at Windows Live, called SkyDrive, you can synchronize folders between your multiple computers. Like, for example, between home and work machine, so you can make sure that two folders on these machines are equal. Works perfectly for source code sharing for my notebooks and desktop, as having multiple versions of hundreds of files is a pain.
Another feature of Live Mesh is remote desktop, which works also through proxy and is just great when you want to log into your home computer but don’t want to set the remote desktop NAT rules. At some point it is more secure, as you won’t forget to switch off your rules later.

I know how hard it is to find a gem in a pile of software and services, so if you have a problem that any of these two programs solve, try them out!

Browser Wars, 09/2011

by Dmitry Kirsanov 8. September 2011 23:06

As a web developer, I do care about browsers performance a bit less than typical web surfers do. I care more about the supported functionality. Whether my website can be viewed on this browser or another and how it will behave.

However, typical web surfers care more about speed and resources of their computers, so when I hear that people prefer Chrome to Firefox, this means my website should look well in that browser as well.

So here is a relative chart of today’s most popular web browsers after testing on my notebook. All numbers are totally relative, but tests included both graphics and data manipulations, the same for each test.

BrowserPerformance08092011

I don’t want to comment on it, as I find these results quite reasonable, but would like to look at the difference between MSIE 9.0 and MSIE 10.0. As you may notice, the Internet Explorer 10’s performance is promising.

So what did I understand from this graph? First of all, I will continue measuring performance of my applications using MSIE 9. And will make sure they are compatible with Chrome 13. And if that’s worth the effort, I will display demos using either MSIE 10 or Chrome. You can keep tracking the performance of browsers on your own equipment using PeaceKeeper website.

Skipping bits

by Dmitry Kirsanov 8. September 2011 11:26

Most of us consider ourselves professionals in what we do. Systems Administrators, Software Developers, whoever else, once we start considering ourselves as professionals, whether it is because others told us so or because we were promoted – that becomes a milestone and an impediment for further development.

Promotion or awe is what puts us into the comfort zone, state of mind when we can easily believe that we are supreme and that will last forever. False sense of security, idea that current state of technologies will stay the same even tomorrow or that we are using the best out of something. And that’s the pitfall.

When you think that you are using only the best features of some technology and that will be enough for today and tomorrow – you are wrong.

So, what this post is about? It’s about the behavior of people who are trying to learn something new, but skip parts they already “know” or won’t need in foreseeable future. First of all, you think you know, and second – you will need the most complicated part of the technology when you least expect it.

As an example – me and WCF, which is Windows Communication Foundation.  During my training  I skipped the security part, as I already knew WSE, I perfectly know Security+ and CISSP, what could be wrong? It took me 2 days to fix a “complicated” configuration of WCF web service at client’s highly secure area. The whole topic would take 3 hours during the training.

File Replacement Utility

by Dmitry Kirsanov 24. August 2011 22:48

Ok, here is another command line tool. This time - for developers who create software made of many components.

Imagine, you have a product which consists of main executable file and multiple dll files. And different people are working on these. And you are deploying it all on multiple machines and never know where it could be hiding. Maybe in some build directories, maybe somewhere else.

So this utility will find all instances of that file and replace with the newest one. Moreover, you can even select the older file, but all files will be replaced by the newest found. Well, there are parameters, of course.

As the searching for files is time consuming, the end result of this utility could be a batch file (.bat) which contains commands to repeat operation. It will take the same source file and put it to the same destinations as during the first run. That way, continuous replacing won't be a problem or take more than a couple of seconds.

So, here it is. Requires .net framework 3.5.

7-Zip Converter

by Dmitry Kirsanov 23. August 2011 23:05

7zip

7-Zip is the most effective file archive format, with which far exceeds ZIP and even RAR in terms of compression level. When I realized that a few years ago, and when all tests proved I could store more files without the need of buying new and expensive hard drive, that was kind of relief, as I have a huge repository of files. A few terabytes.

You would ask why do I need so much storage, but the fact is – among other trades I am also a trainer, and I need to store my training materials somewhere. And these are mainly not the media files, which are generally well compressed and couldn’t be squeezed further, but documents and images of hard drives and DVDs. Anyway – something that could be compressed.

The problem was – all these thousands of files were already compressed by ZIP. The least effective but also the most compatible file format. I own a license for WinRAR, so opening any sort of archive isn’t a problem for me, but I didn’t want to either keep old files in ZIP form when I could compress them up to 10 times better, nor convert ZIP files to 7-ZIP manually. No, I needed to convert ZIP files to 7-ZIP automatically.

WinRAR, is quite useful and user-friendly (even though it has one of the worst customer support in software industry), it's compression ratio is not the best, comparing it to less visually attractive free 7-Zip. However, since my precious archives consuming terabytes of data, and hard drives are still quite expensive, especially when you are planning for some redundancy, space becomes more important than graphical user interface of archiver's shell.

However, one little freeware thing that comes with WinRAR is called “RAR converter”, or “rarcvt”. It comes in form of command line utility and is able, using WinRAR, decompress other archives, be it ZIP, CAB, ARJ or even ISO and RPM into RAR. I wanted that functionality for 7-ZIP, but it was nowhere to be found.

So I had to create it myself. I took Visual Studio and in a few hours made what is called now a 7-ZIP converter. This command line utility was tested on thousands of nested archives and proved to improve the efficiency of data storage from at least 1 and up to 99%. Sometimes there were situations when I couldn’t believe my eyes how it was able to repack the ZIP file to 7-ZIP for the end file to be 100 times smaller than ZIP!

I believe that this utility is essential for file server system administrators, as well as for home servers or even personal notebooks, where storage space is quite limited. It does not require installation, but you should have .NET framework 3.5 installed (you already have it in Windows Vista and Windows 7) and, of course, 7-zip. Config file can be edited in Notepad, it has just 3 parameters - the path to 7-zip, path to temporary directory and extensions of archives that should be converted.

Utility finds files by file mask, may convert nested archives (that is - when you have one archive inside of another), can delete the original file after conversion and may set the time stamp of original file to the resulting 7-zip archive.

Well, here it is!
