What Nokia's Windows move means for Open Source

What Nokia's Windows move means for Open Source: "

When Nokia announced that it was going to use Microsoft’s Windows Phone 7 for its smartphones some people saw this is a great move. Other folks, like yours truly, saw Nokia and Microsoft partnering being as dumb as betting that the Pittsburgh Pirates will win the 2011 World Series. But, what do Nokia’s open-source partners think of this move? I asked, and as you might guess, they’re not happy.

Jim Zemlin, head of The Linux Foundation tried to make the best of it, “The Linux Foundation is disappointed in Nokia’s decision today to choose Microsoft as the primary platform for its mobile phones. Tough times give birth to difficult decisions that we don’t always agree with, but open source is–at its core–about choice. We believe that open source software is more than a sum of its parts, and the market is currently bearing that out. The Linux Foundation is here to enable collaboration among its members and the Linux community, and we invite participation in MeeGo [an embedded Linux for smartphones and other devices that was supported by Intel and Nokia] and any of our other many projects and programs.”

I might add that Nokia is a gold member of the Linux Foundation. Nokia’s been a member of the Foundation since 2007. The Linux Foundation itself had been, and I presume will continue to be a big MeeGo supporter. Nokia’s move to Windows Phone 7 could not have made the Foundation nor its members happy.

In particular, although Nokia has said it will continue to support MeeGo, Intel, Nokia’s chief MeeGo partner was not pleased. In a statement Intel said:

While we are disappointed with Nokia’s decision, Intel is not blinking on MeeGo. We remain committed and welcome Nokia’s continued contribution to MeeGo open source.

Our strategy has always been to provide choice when it comes to operating systems, a strategy that includes Windows, Android, and MeeGo. This is not changing.

MeeGo is not just a phone OS, it supports multiple devices. And we’re seeing momentum across multiple segments–automotive systems, netbooks, tablets, set-top boxes and our Intel silicon will be in a phone that ships this year.

Still, you have to believe that Intel feels hosed by Nokia’s move.

Another open-source group that’s wondering what’s going to happen next is Nokia’s Qt division. Qt is the cross-platform framework behind both MeeGo and the KDE Linux desktop. Now, though, Qt looks like it’s irrelevant to Nokia’s future.

Aaron Seigo, a leading KDE developer and one of the chief designers of the KDE 4 desktop, wrote on his blog that “While I have little good to say of the announcement that was made, what remains of interest to me is the level of investment in Qt, the strategic positioning of MeeGo going forward and what KDE’s role can and will be as both of those things continue to mature.”

Seigo continued, “Open governance around Qt is moving forward briskly and from what I gather there are some interesting and useful announcements to come. R&D investment continues. However, we (KDE) won’t know the full shape of how this will impact our landscape in the mid- and long-terms until we speak more with people at Nokia as well as within the Qt team itself. That’s going to take weeks, not hours or days.”

I asked Seigo for more of his thoughts on the matter and he replied, “The most important thing to keep in mind is that Qt is licensed under the LGPL (Lesser General Public License) and has a broad ecosystem around it. Regardless of what happens at Nokia, it won’t be the end of the world.”

While Qt’s licensing situation is complicated, with no fewer than three possible licenses, the bottom line is that it’s relatively easy to legally use Qt in software projects.

Seigo added, “That said, it is far, far too early to say anything conclusive about what it means for Qt and therefore by extension to F/OSS [Free and Open-Source Software] communities like KDE and their projects. We’re (KDE) putting together an internal task force to work through these topics with Nokia as well as the broader Qt community and it will need a few weeks to arrive as useful conclusions.”

“It’s a dynamic situation that we’re taking seriously and tracking, but we’re also being careful not to jump the gun and either miss opportunities that arise as a result or make poor reactive decisions to challenges as yet not fully understood,” he concluded.

That sounds like a fair assessment to me. We’re going to need to wait and see.

I will add one more thing, from where I sit, Android is actually the least effected open-source project by Nokia’s moves. MeeGo, followed by KDE and other Qt users are the ones with something to be concerned about. Google and its Android friends? I think they could care less.

Our Universe is an enormous place; that’s no secret. What is up for discussion, however, is just how enormous it is. And new research suggests it’s a whopper – over 250 times the size of our observable universe.(...)

How to Automatically Backup your Files with Dropbox

How to Automatically Backup your Files with Dropbox: "

dropbox backupDropbox offers 2 GB of free online storage space that you can easily bump up to 3 GB or more with the help of your social networks and by inviting friends who aren't on Dropbox yet.

This kind of space is not sufficient to backup the entire hard drive1 but enough to save your essential files and folder that you can’t afford to lose. These may include your documents, photographs, source code and other important files.

Using Dropbox for File Backup

Backup with Dropbox is effortless but one big limitation is that your files and folders need to be residing inside the main Dropbox folder before they can be sent to the cloud.

To deal with this problem, we’ll make use of Microsoft SyncToy, a free application that keeps files and folders in sync with each other. You identify all the essential folders that you want to backup and then sync them all with the local Dropbox folder using SyncToy.

Next we’ll use the built-in Task Scheduler in Windows to run SyncToy once per day (or sooner) so that the content of our local Dropbox folder and the source folders are always in sync with each other.

Backup with Dropbox – Step by Step

Now that you have the basic idea, lets see how this can be implemented in in few easy steps (you can also skip straight to the video tutorial).

Step 1. Launch SyncToy and create a new folder pair. For instance, to backup documents, set the “Left Folder” as your My Documents folder and the “Right Folder” as a sub-folder of Dropbox. Set the action as ‘synchronize.’

Step 2. Repeat Step 1 for every folder that you want to back up using Dropbox. If you want to backup all your pictures, just point the left folder to the main ‘My Pictures’ folder or choose individual folders if you don’t have space to backup the entire archive.

Step 3. Enter taskschd.msc in the Windows Run box to start the Task Scheduler or go to Start –> All Programs –> Accessories –> System Tools –> Scheduled Tasks.

Step 4. While you are inside Task Scheduler, create a basic task and give it a name like ‘Dropbox Backup.’ Set the trigger as Daily (run backup once per day) and choose a time when you are less likely to use your workstation.

Step 5. Under Action, choose “Start a Program” and set the program name as SyncToyCmd.exe. For arguments, just say “-R” without quotes and save the task.

That’s it! SyncToy will launch everyday at the set time and will put all the new and updated files into Dropbox. Once there, Dropbox will automatically copy your files to the cloud which you can then access from anywhere from almost any device.

Logisim: Open source digital logic simulator

Logisim: Open source digital logic simulator: "

[Spi Waterwing] wrote in to make sure that we were aware of Logisim, a Java-based open source digital logic simulator. We’ve used Atanua quite a bit in the past but hadn’t heard of this program. It seems to have a pretty big educational following and right off the bat it’s got a feature we’ve always wanted, the ability to build your own ‘black box’ logic devices. That is to say you can build your own circuit out of logic gates and then package it into a part to be plopped into your next design. What it doesn’t have is the series logic chips that we’re used to with Atanua, but you can build your own with the black box feature if you really need that kind of functionality.

So grab a copy and try building that binary calculator project from last month.
