Ubuntu 10.04 hit by major bug on release day
Ubuntu 10.04 hit by major bug on release day: "
It's the end of April. Spring is here, and so is Ubuntu 10.04. Or at least, that's the plan. Canonical's rigid release schedule is awesome for many reasons -- one of which is the amount of excitement it generates around each new Ubuntu release. However, I don't think this is the kind of excitement Mr. Shuttleworth had in mind when the 'fixed schedule' policy was set.
As it turns out, after the final release ISOs were already created (or 'spun' in Ubuntu geek-speak), a critical bug came up; and no, I don't mean something like 'OMG, we put the window buttons on the wrong side!'. I mean something like 'once you install Ubuntu, you will not be able to boot your other operating system.' Oops. It doesn't kill the other OS, and it's fixable when it happens (it's a problem with the GRUB2 bootloader configuration), but it's certainly not something you want to have happen to people just trying out your OS (or even upgrading from previous versions).
Granted -- it doesn't happen with each and every installation, but it can happen. The Ubuntu team considered a quick-fix, but eventually went for the more responsible (and safer, in terms of PR) option of re-spinning the ISOs. However, re-spinning all ISOs would push the release into May, which would be a PR flop in itself. So they're just re-spinning some of the most popular ones, like the x86 and x64 desktop releases, as well as the Netbook remix. Exciting stuff!

Using netstat: "
As promised (in my article “How do I find my network information in Linux?“) I am going to introduce you to the netstat command. This command is a very useful tool for discovering networking information such as routing tables, network connections, interface statistics, masquerade connections, and multicast memberships. But it’s not quite as simple to use as some of of the other “discovery” tools (such as ifconfig). With netstat you really do need to know what you’re looking for and how to find it. This article will help you to understand just that.

Sony shutting down Japanese floppy disk sales by March 2011, kills a tech dinosaur
Sony shutting down Japanese floppy disk sales by March 2011, kills a tech dinosaur: "
Believe it or not, Sony managed to shift 12 million 3.5-inch floppy disks in Japan last year -- presumably to die-hard old schoolers. Alas, time waits for no one, and the venerable data transporter that started its life way back in 1981 is going to all but cease production by March of next year. Sony was the last of the major manufacturers to keep churning these bits of plastic out, but soon that too shall be no more. Having already shut down operations in most of the world, it's now noted the end of life for its domestic market, and thereby effectively consigned the floppy to the past. Good riddance, you might say, but we still remember fondly the wonder we experienced upon tearing apart our first 5.25-inch floppy. Ah well, the diskette goes the way of the cassette, guess that was predictable.

A explicação do erro pode ser consultada aqui Article ID: 321044
Basicamente, o que erro quer dizer é que existe duas contas de computador que estão em conflito. Para corrigir o problema bastará procurar quais as contas recorrendo à aplicação ldifde.exe
exemplo: ldifde -f check_SPN.txt -d "DC=mydomain,DC=com" -l servicePrincipalName -r "(servicePrincipalName=host/mycomputer.mydomain.com)" -p subtree
Substitui DC=mydomain,DC=com pelo do root name space correto e pelo FQDN da máquina damycomputer.mydomain.com
Em alternativa podem executar este vbs.
Depois de encontradas as contas, terá que apagar uma delas. Para tal executa a consola de Utilizadores e Computadores da AD, dsa.msc, procura a conta de computador e "delete".

Luckybackup: Linux backup made easy
Luckybackup: Linux backup made easy: "
There are a lot of backup tools out there. From the overly simple to the overly complex. Many of those backup tools go unnoticed and unused. Some of them get recognized as the outstanding projects they are. One of those tools is Luckybackup. This tool was awarded Sourceforge’s best new project of 2009. There is a reason for that. Luckybackup is a simple to use backup tool that can backup both to a local machine and to a remote machine – with a user-friendly gui and all the features you would expect in a backup tool.
You might think that Luckybackup is a tool only an end-user could love. Not so. Although Luckybackup is simple to use, open source, and free it’s a worthy candidate for business backup as well. Oh sure, you’re not going to image your machines with this backup tool, but you can backup your data. In this article I am going to show you how to install and use Luckybackup.

Google releases major overhaul of Google Docs; faster, more responsive, better collaboration
Google releases major overhaul of Google Docs; faster, more responsive, better collaboration: "
It's hot off the press, and still being slowly unrolled, but the Google Docs blog has just announced some major changes to its office productivity suite of web tools. You can stop reading now and watch the video if you want to find out what's new, or read on for some bullet points!
As I said earlier, not everyone has access to the new version yet, but you should be able to toggle it within the next few days. Spreadsheet users will see a button appear at the top of the page, while you have to go into Settings > Document Settings to enable the new document editor.
Meanwhile, there's a counterpart post up on the Google Enterprise blog with more technical details on the new implementation of Google Docs. Imported documents will be of a higher fidelity, with more-accurately preserved formatting. Also worth noting is that the new Google Docs does not support Gears -- as a result, offline support is disappearing from 3 May 2010. Google is busy working on an HTML5 solution and the offline option should reappear soon after.

It's hot off the press, and still being slowly unrolled, but the Google Docs blog has just announced some major changes to its office productivity suite of web tools. You can stop reading now and watch the video if you want to find out what's new, or read on for some bullet points!
- Faster -- what with Google Docs being entirely in the browser, things can sometimes get a bit slow with JavaScript doing the majority of the work. With this new version of Docs, pages will load faster, spreadsheets will manipulate more quickly.
- More responsive -- seemingly, Google's purchase of EtherPad was actually to bolster Google Docs rather than Wave! This new version of Docs features a more-responsive, real-time word processor -- you'll be able to experience collaborative projects character-by-character.
- Better collaboration -- the new version of Google Docs features a collaborative drawing editor; neat. Take a look at a screengrab of it (it's not enabled yet -- later today, Google says).

Want to breathe new life into your netbook? Here’s a quick look at Jolicloud, a unique new Linux based OS that lets you use your netbook in a whole new way.
Netbooks have been an interesting category of computers. When they were first released, most netbooks came with a stripped down Linux based operating system designed to let you easily access the internet first and foremost. Consumers wanted more from their netbooks, so full OSes such as Windows XP and Ubuntu became the standard on netbooks. Microsoft worked hard to get Windows 7 working great on netbooks, and today most netbooks run Windows 7 great. But the Linux community hasn’t stood still either, and Jolicloud is proof of that. Jolicloud is a unique OS designed to bring the best of both webapps and standard programs to your netbook. Keep reading to see if this is the perfect netbook OS for you.

10 reasons why Windows Terminal Services is becoming more popular
10 reasons why Windows Terminal Services is becoming more popular: "
When Terminal Services debuted with Windows NT, server hardware was hard pressed to support multiple server sessions. Furthermore, 10 Mbps networks were still the standard at that time and could easily become saturated by network-intensive applications, such as Terminal Services. Today, server hardware is far more powerful than it has ever been, and running multiple operating system instances on a server is the norm. Today’s servers are well equipped to handle the demands of hosting Terminal Service sessions.

If you've noticed your Firefox installation seems a bit more stable since you upgraded to Firefox 3.6, you're not alone. According to statistics collected by Mozilla, Firefox 3.6 is 30 percent more stable than its predecessor, and Firefox crashes are down 40 percent across the board. Firefox-focused blog Mozilla Links reports that the, overall, crashes dropped 'from about 6.5 crashes for every 100 users, to around 2.5.' Even better: those numbers should drop even more significantly now once Firefox Lorentz's isolated plug-in architecture leaves beta and becomes the standard for the majority of Firefox users.

After a decade of vehement distrust for its open source cousin, Microsoft looks like it is finally ready to embrace one of the features that makes Linux and its variants so damn desirable.
Speaking frankly, Garrett Serack of Open Source Development at Microsoft laments the current state of open source package management and installation on the Windows platform.

Google Docs Windows Explorer Integration (Ask The Readers)
Google Docs Windows Explorer Integration (Ask The Readers): "
Now that I have decided to run a computer system without local pdf reader installed I had to find another comfortable way of dealing with pdf documents. I’m currently using Google Docs for the purpose which is not that big of a nuisance because I have to open pdf documents rarely and I have the web browser open most of the time to access Google Docs in just a few clicks.
One thing however that bothers me a little bit is that there does not seem to be a way to integrate Google Docs in Windows Explorer natively. Natively meaning without a software or application running in the background that provides that functionality.
I have discovered several programs that can be used to send documents from Windows Explorer to Google Docs. These include Quick Tools for Google Apps or Google Docs Uploader but their functionality is only available for as long as the programs are running.
I’m more looking for a solution that integrates the upload into Windows Explorer without a software running in the background all the time. Much like the Virus Total Uploader is offering. The program only starts up if the user selects the option to send the selected files to Virus Total.
The question is: Is there a way to integrate Google Docs into Windows Explorer without a permanent process in the background that is providing that functionality?

Qubes uses virtualization, sandboxing to deliver a more secure desktop OS
Qubes uses virtualization, sandboxing to deliver a more secure desktop OS: "
It's probably a safe assumption that if a project to design a new operating system involved an experienced security researcher that the goal would be an OS which is darn near bulletproof. That's exactly what Joanna Rutkowska is gunning for with Qubes, which she's pegged for release later this year.
Qubes is a bit different from the desktop OSes most of us are familiar with, though it looks similar. It's built on Fedora and Xen and aims to deliver a more secure desktop through the use of sandboxing and 'App VMs.' Each VM is isolated, though you're still able to do pass data between them (via secure copy and paste).
There's a price to pay in terms of system resources for the added security, but it's reasonable. A typical App VM uses about 400MB of memory but can run a handful of apps in that space (e.g. Firefox, Thunderbird, and OpenOffice).

RJ TextEd: Free Text Editor with Syntax Highlighting and Code Folding: "
Windows only 
I’m always on the look out for awesome text and code editors, but the percentage that turn out to be good versus the number I actually test is fairly low. RJ TextEd ranks pretty high in that list though. It’s free, portable, and has a very extensive list of features. In fact it has so many features that at first glance it may seem overwhelming.

One thing I’ve never taken lightly is making sure all of my most important data is backed up. Utilities like SyncBack have served me well over the years, and I’ve even gone as far as to buy a copy of the software for my primary PC. For my other computers I switch on and off between other tools, and one of the more recent ones is FreeFileSync.

Geek Gifts 2010: Alienware M11x gaming notebook
Caros amigos e amigas,
Comecem já a poupar $$$ para me oferecerem um destes :)
Geek Gifts 2010: Alienware M11x gaming notebook: "
Alienware has a reputation for making really nice gaming personal computers for what has been dubbed as the enthusiast market. In more common language, computer enthusiasts don’t mind paying more for hardware that meets a high standard for performance and style. Since my current personal Alienware gaming desktop is my fourth PC purchased from this company, I guess that makes me an enthusiast.
But the Alienware M11x is a slightly different kind of notebook for the company. Oh sure, it still has a fast CPU and GPU, and it still rivals any other notebook when it comes to performance, but this Alienware is different because it is netbook-sized.

Update
Process Explorer v12's new server administration features: "
—————————————————————————————————
Process Explorer, which is arguably one of the most frequently used Sysinternals tools, has been updated to version 12. The latest version includes a number of new features that allow server administrators to see what program, service, or system process is interacting with a file. According to this TechNet blog, the update also includes a number of other minor improvements and bug fixes.
The significant new features for the popular diagnostic tool include the following:
Process Explorer has a lot of tabs and views, so it may take you a while to find the new features. Figure A shows the new feature that displays the TCP/IP information of a given process.
Figure A
Figure B shows an example of the new feature that will display a Windows service name to a running thread. This feature detects if a thread has been started by a service.
Figure B
In Figure B, the two processes on the left (vpxd and JettyService) were originated from a Windows service and have the Service tab visible. On the right, the user process (Firefox Web browser) does not have a Service tab.
You can install Process Explorer version 12 via a free download from the Microsoft site. This update of Process Explorer works for Windows Server 2003 and higher. It also works on Windows XP and higher. This tool continues to hold the crown of most useful in my book.
Process Explorer is the most useful tool that I use in my server admin work. What do you think of Process Explorer? How do you use it? Share your thoughts with the TechRepublic community.

Use Vaseline To Make Scratched CDs Work Again [DIY]
Use Vaseline To Make Scratched CDs Work Again [DIY]: "
Rubbing Vaseline on scratched CDs to make them readable again is a new one to me, but Instructables has a DIY project up claiming it works perfectly. Mind you, they also say peanut butter works a charm too.
Using a piece of cloth, the Vaseline can be slicked onto the scratched CD, and then rubbed off with some rubbing alcohol on a cotton ball, leaving the Vaseline in the scratches, filling them in. It won't remove the scratches completely—that would be a miracle—but it sounds like it does a nice job of filling them in to make the disc work again. [Instructables via Lifehacker]"
