Restoring XP backups in Vista

Filed under: — Aviran Mordo

Windows Vista’s Backup and Restore tools are completely different from the Backup program that came with Windows XP and so the backup files are incompatible. What do you do if you need/want to restore a Windows XP backup in Windows Vista?

Fortunately, Microsoft took this scenario into account and provided a supplemental utility called the Windows NT Backup - Restore Utility that you can download and install in Vista. You can then use it to restore a backup made in Windows XP from within Windows Vista.

Before you actually install and run the Windows NT Backup - Restore Utility, you must enable the Removable Storage Management feature. (If you don’t, you may receive an NTSMAPI.DLL error.) To do so, access the Control Panel from the Start menu and click the Programs item. Once the Programs window appears, locate and select the Turn Windows Features On or Off command under the Programs and Features heading. When you do, you’ll encounter a User Account Control (UAC) dialog box and will need to respond accordingly.

When you see the Windows Features dialog box, locate and select the check box next to Removable Storage Management option to turn the feature on. Then, click OK. When you do, you’ll see a progress dialog box and it may take a minute or two to turn on the Removable Storage Management feature.

Once the Windows NT Backup - Restore Utility is installed, you can launch it from the Start menu. Oddly enough, Vista doesn’t recognize the utility at all and displays a UAC that calls it an unidentified program. To continue, just click the Allow button.

You’ll then see the main Windows NT Backup - Restore Utility. The Utility window contains two tabs allowing you to either use the Restore Wizard on the Welcome tab or to perform a manual restore operation on the Restore and Manage Media tab.

Tip: Make Old extensions Work In Firefox 2

Filed under: — Aviran Mordo

When firefox gets updated some of the extensions gets disabled. The reason for that is that Firefox extensions need to define in what version of Firefox they work. But in many cases extensions authors don’t update their extension version, or it takes some time after a new version of Firefox is introduced until a new version of the extension is out.

Firefox by default disables extensions that do not match the version, although they can still work without problems.

The first thing that you can try is to use the Nightly Tester Tools extension.

This extension adds a few extras useful to those that regularly test nightly builds of Firefox and Thunderbird.

Features:

  • Allows you to force the application to believe an extension is compatible with the current version and enable it.
  • Allows copying the build identifier and a list of installed extensions to the clipboard.
  • Adds a toolbar button to let you insert the build identifier into the current text box (Not supported in the Application Suite).
  • Lets you customise the title bar to include the build identifier and other information.
  • Provides talkback integration allowing you to quickly view recent incidents as well as a sidebar that shows all incidents still on your machine (you may be surprised at just how many there are).
  • Adds a simple interface for parsing nspr log files for leaks.
  • Lets you take a screenshot of any open window and save it as an image, copy it to the clipboard or submit it to Imageshack (not yet fully functional in cairo builds).

If this does not work you can try to tell Firefox which versions of extension to work with by changing the browser’s settings

Tip: Reduce Firefox Memory Usage

Filed under: — Aviran Mordo

Many Firefox users notice that the open source browser can take a lot of memory, sometimes several hundreds of mega bytes. Fortunately Firefox lets you control to some extent how much memory it will consume.

To set the configurations you’ll need to edit Firefox settings. To do that you’ll need to type about:config in the address bar and edit the keys we’ll discuss in this article.

Cached Pages
When a page is loaded, it can be cached so it doesn’t need to be rerendered to be redisplayed. As a default Firefox will set the amount of cache memory according to the total amount of RAM your system got. The problem with that is that these values are per tab, so the more tabs you’ve got opened the more memory Firefox cache takes.

The config parameter is browser.cache.memory.capacity and you can set it to the number of KB you want let Firefox use for cache. Value of 0 will tell Firefox not to use any memory for cache. Note that the parameter browser.cache.memory.enable has to be true

The default value is -1 where Firefox will set the memory usage according to the following values

Physical RAM Memory Cache (in KB)
32 MB 2048
64 MB 4096
128 MB 8192
256 MB 14336
512 MB 22528
1 GB 32768
2 GB 45056

4 GB 59392

In Firefox 2 these defaults will change to the following:

Physical RAM Memory Cache (in KB)
32 MB 2048
64 MB 4096
128 MB 6144
256 MB 10240
512 MB 14336
1 GB 18432

2 GB 24576
4 GB 30720

To view current memory cache usage, type about:cache?device=memory in the address bar


Pages Stored In Memory

Pages that are visited are stored in memory in such a way that they don’t have to be re-parsed. Although it sounds like cache this is different from the cache. This setting improves performance of Firefox when pressing Back and Forward buttons.

The setting key to control this behavior is: browser.sessionhistory.max_total_viewers. The default value is -1 where Firefox use the following settings based on the amount of memory your system has.

RAM Pages
32MB 0
64MB 1
128MB 2
256MB 3
512MB 5
1GB 8
2GB 8

4GB 8

This preference limits the maximum number of pages stored in memory. Setting the value to 0 do not store any pages in memory.


Let Windows claim back memory
On Windows operating systems, when a program is minimized and left for a period of time, Windows will reclaim the memory the program used in anticipation that other programs might need it. Because of the way Mozilla applications are stored in memory, Windows is much more aggressive in reclaiming the memory they use, which can cause a delay when the program is restored. This preference determines whether to allow Windows to reclaim memory from a minimized Mozilla application.

Firefox’s default setting prevents Windows from reclaiming memory when the program is minimized.

To change this settings you’ll need to change or create the key config.trim_on_minimize and set it to true or false. True - allows Windows to reclaim back the memory and false (default) prevents Windows from doing that.

Note: Changing Firefox’s settings may not be enough to stop it from taking too much memory, plugins can also be a big factor in memory consumption.

Tips on Notebook Computer Use

Filed under: — Aviran Mordo

Notebook computers are now a part of modern life. They can be found in offices, schools and homes across the country. There are tens of millions of portable computers in use. The U.S. Consumer Product Safety Commission (CPSC) is aware of at least 47 incidents involving smoke or fire associated with notebook computers, from January 2001 through August 2006. To promote safe use of notebook computers, batteries and chargers, CPSC offers the following tips:

  • Do not use incompatible computer batteries and chargers. If unsure about whether a replacement battery or charger is compatible, contact the product manufacturer.
  • Computer batteries can get hot during normal use. Do not use your computer on your lap.
  • Do not use your computer on soft surfaces, such as a sofa, bed or carpet, because it can restrict airflow and cause overheating.
  • Do not permit a loose battery to come in contact with metal objects, such as coins, keys or jewelry.
  • Do not crush, puncture or put a high degree of pressure on the battery as this can cause an internal short-circuit, resulting in overheating.
  • Avoid dropping or bumping the computer. Dropping it, especially on a hard surface, can potentially cause damage to the computer and battery. If you suspect damage contact the manufacturer.
  • Do not place the computer in areas that may get very hot.
  • Do not get your computer or battery wet. Even though they will dry and appear to operate normally, the circuitry could slowly corrode and pose a safety hazard.
  • Follow battery usage, storage and charging guidelines found in the user’s guide.

Tip: Enable Access To All Folders In The Recovery Console

Filed under: — Aviran Mordo

If you have SP2 installed already, there is an easy way to enable access to all files and folders in the Recovery Console. This requires the user to modify a setting using the Group Policy Editor (gpedit.msc).

1) Start>Run>gpedit.msc

2) Once the GPE console opens, expand Computer Configuration by clicking on the + sign left of it.

3) Expand the Windows Settings folder by clicking the + sign left of that.

4) Expand the Local Policies folder by clicking the + sign left of that.

5) Click on the Security Options folder. A long list of configurable options comes up in the window pane to the right.

6) Scroll down until you find:: Recovery Console: Allow floppy copy and access to all drives and folders.

7) Right click on it and select Properties, which appears in bold.

8) Click on the Enabled radio button.

9) Hit OK.

10) Reboot.

Congratulations, you can now access all files and folders on the system, and you can copy to/from floppy drives all while inside the Recovery Console.

Strict warning to anyone messing about in the gpedit.msc: You can totally screw up your Windows install if you change options in there without knowing what you are doing. CHANGE SETTINGS IN THERE AT YOUR OWN RISK!

Also, there is an option above that, called Automatic Administration Logon that will automatically store and log in the Administrator account information when you try to log into the Recovery Console. Very useful in situations like this. Just enable it, and you aren’t bothered with trying to remember the admin password credentials, Windows will automatically log into the Recovery Console for you with this option enabled.

Thanks for thejynxed from the forum for this tip

Tip: Installing Maven 2 Behind A Proxy

Filed under: — Aviran Mordo

If you are a java programmer you probably know the Ant build tool. However creating an Ant build script can be very complicated, and hard to maintain. The apache group recently released a new build tool called Maven (which is now in version 2), and it makes the build scripts very easy to create.

Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project’s build, reporting and documentation from a central piece of information.

Indeed getting started with Maven is pretty strait forward, however if you are working in a corporate network and behind a firewall this simple step of configuring maven to use the corporate proxy will save you a lot of time and aggravation.

Edit your maven configuration file settings.xml under maven-2.0.x/conf

Now we need to configure a proxy. In the settings.xml file find the element and add the following child element under it:


<proxy>
   <id>myproxy</id>
   <active>true</active>
   <protocol>http</protocol>
   <host>proxy.yourcompanydomain.com</host>
   <port>80</port>
   <nonproxyhosts>localhost|158.187.*</nonproxyhosts>
</proxy>

Note the <nonProxyHosts> element. This element is needed to bypass proxy for local network access, such as for working with local corporate repository

Tip: Know The Recovery Console Commands

Filed under: — Aviran Mordo

The recovery console is used to troubleshoot and repair damaged Windows installation.

Many users are not aware that when working with the recovery console, although it looks like a regular command prompt, you actually have a different set of commands that you can use than the regular command prompt.

Also your disk access is restricted to the Windows folder and to the root folder of your hard drive ( you still have access to the floppy drive, if you have one)

Here are the recovery console list of commands.

  • Attrib - Changes the attributes of a file or directory.
  • Batch - Executes the commands specified in the text file.
  • Bootcfg - Boot file (boot.ini) configuration and recovery.
  • ChDir (Cd) - Displays the name of the current directory or changes the current directory.
  • Chkdsk - Checks a disk and displays a status report.
  • Cls - Clears the screen.
  • Copy - Copies a single file to another location.
  • Delete (Del) - Deletes one or more files.
  • Dir - Displays a list of files and subdirectories in a directory.
  • Disable - Disables a system service or a device driver.
  • Diskpart - Manages partitions on your hard drives.
  • Enable - Starts or enables a system service or a device driver.
  • Exit - Exits the Recovery Console and restarts your computer.
  • Expand - Extracts a file from a compressed file.
  • Fixboot - Writes a new partition boot sector onto the specified partition.
  • Fixmbr - Repairs the master boot record of the specified disk.
  • Format - Formats a disk.
  • Help - Displays a list of the commands you can use in the Recovery Console.
  • Listsvc - services and drivers available on the computer.
  • Logon - Logs on to a Windows installation.
  • Map - Displays the drive letter mappings.
  • Mkdir (Md) - Creates a directory.
  • More - Displays a text file.
  • Net Use - Connects a network share to a drive letter.
  • Rename (Ren) - Renames a single file.
  • Rmdir (Rd) - Deletes a directory.

IT Salary Negotiation Tips

Filed under: — Aviran Mordo

Negotiating or renegotiating your salary is, to say the least, a delicate dance. You want the folks that control the purse strings to show you the money, and if your workplace is like most, they’d rather keep it in their seemingly gold-lined coffers.

Your company might be willing to bend a little, but will avoid disclosing how much from the outset. You’re worried about asking for too much, thus seeming presumptuous; but if you ask for too little, you may be selling yourself short.

But it doesn’t mean it can’t be done. With a little bit of preparation, advice from bosses and experts, and that old fallback, common sense, you’d be surprised to find income negotiation wiggle room where it might have seemed impossible.

eWEEK rounds up tips from pros about when to negotiate or renegotiate, how to prepare yourself, what to never do and even when to fold your cards. But, with good preparation, that should be a lot less likely.

Everything You Need to Know About Alternate Data Streams

Filed under: — Aviran Mordo

Alternate Data Streams is used by recently discovered Rootkit to hide itself from the being discovered. By using Alternate Data Streams you can totally hide files from the user and from Anti-Virus applications

What is an alternate data stream (ADS)?
In NTFS, a file consists of different data streams. One stream holds the security information (access rights and such things), another one holds the “real data” you expect to be in a file. There may be another stream with link information instead of the real data stream, if the file actually is a link. And there may be alternate data streams, holding data the same way the standard data stream does.

heysoft.de published a page called: FAQ: Alternate Data Streams in NTFS which gives you all the information about Alternate Data Streams.

Tip: Use Your WebMail As A Remote Drive With RoamDrive

Filed under: — Anthony Rousseau

Do you know about RoamDrive ?

RoamDrive is a great application that permits you to upload whatever data you want in the free store space on one of your webmail accounts. You can choose between GMail (about 2700MB actually), Hotmail (non-paying up to 250MB & paying up to 2GB),MSN (paying up to 2GB) and (maybe) Yahoo! Mail soon.

It acts exactly like a Hard Disk Drive. You can simply Drag&Drop files or folder from your computer in the application window. RoamDrive will just compress it and then upload it directly on your webmail account.

You will be able to access you file on any computer you want in the world : just install RoamDrive on it and then connect to your account.

The difference between RoamDrive and GMail Drive is that RoamDrive,allows you to upload files greater in size than 10MB, and you are not limited to file names of 40 characters maximum. It is free, there is no adware in it and the minimum system requirements you will need to meet are any version of Windows XP and the Microsoft .NET Framework version 1.1. Actually it is a beta version.

You can learn more and download it by checking their website here : RoamDrive beta.
