Government “committed” to using more open source

http://www.computerworlduk.com/news/public-sector/3239664/government-committed-to-using-more-open-source/

Flexibility of open source makes it attractive

The government has said it is "committed" to using more open source software "where possible".

In a parliamentary written answer yesterday, Francis Maude, Minister for the Cabinet Office, said that the government will "actively and fairly" consider open source and proprietary solutions in its procurement decisions.

"Procurement decisions will be made on the basis of the best value for money solution to the business requirement, taking account of total cost of ownership of the solution.

"Where there is no significant overall cost difference between open and non-open source products, open source will be selected on the basis of its additional inherent flexibility," he said.

However, Maude said that the government had not made any estimates on the possible cost savings from moving to open source.

"While more open procurement can undoubtedly save money, it is difficult to ascertain precise cost savings from open source software alone as it is one element in the overall solution," he said.

Maude said that the Cabinet Office was working with the Office of Government Commerce on a "Guidance for Procurers", which focuses on open source software.

A recent survey by Accenture revealed that more than two-thirds of businesses expect to increase their investment in open source software in this year.

Meanwhile, last week Atos Origin became the first supplier to announce that it had signed a memorandum of understanding (MoU) with the government to launch a 'single-client' approach to IT procurement.

India's $35 Android 7-inch Tablet to Hit in January

http://www.tomshardware.com/news/india-android-tablet-35-indiapad,11255.html

5:50 PM - September 9, 2010 by Jane McEntegart - source: Tom's Hardware US


We've been hearing about India's plans for a $35 computer for a few months now, and for a while we thought it might be all talk. However, it seems India is pushing ahead with plans for the educational tablet.

Zoom

Engadget reports that India has just awarded the manufacturing contract to HCL Technologies. The first shipment will supposedly only contain the 7-inch model and is set to arrive on January 10. It's unclear if the $35 price has stuck or whether India's been successful in plans to eventually drive the price down to $10 with the help of large orders and government subsidies.

Unveiled by the Human Resources Minister of the Union of India, Shri Kapil Sibal, in July, the device has generated significant interest among colleges and schools. The tablet device will have web browsing, including the ability to access YouTube. Official specs have yet to be confirmed, but it's said to have WiFi, come in a variety of sizes, and pack 2GB of storage. Though the press release is hard to decipher, it would seem the Indian government also has plans to launch a wesbite containing quality educational content for the devices.

Google Reader 使用技巧

http://www.xjp.cc/2010-log/09/reader-tips-and-recommended-rss.html

假设我关注3个新闻网站、5个财经网站、30个博客、4个社区,这意味着查看这些网站的信息即便只全部打开一遍都会消耗惊人的时间。而且这个部分可能会面临更大的时间成本,因为你打开的时候可能它们并没有更新,或者没有更新你感兴趣的内容。这种频繁刷新以及获取内容的不确定感,一定程度就会产生信息焦虑症,你就会频繁地刷新网页,然后一直心慌慌。

  在有了RSS技术后,你以前需要打开N个网页,现在只需要打开阅读器添加对应的RSS订阅,然后就可以获取订阅网站的最新更新。如果它们的RSS提供了全文输出,那么你甚至在阅读器里面看到全部内容,设置包括图片、音乐、视频等多媒体内容。所以RSS最大的革新是让大家从信息的包围中解脱出来,剪掉了中间步骤让用户可以把更多焦点集中在内容本身。

  RSS阅读器有国内的、有国外的,有客户端的、也有WEB的,那为什么选Google Reader呢?第一WEB应用是未来趋势,第二Google是巨头大树好乘凉,第三Google Reader是无界限的,世界更精彩。

  很多用户在刚使用Google Reader的时候,不得门而入抓不住诀窍,我总结了几个常见的新手技巧分享给大家:

  1、使用https方式连接不容易出问题。

  2、侧边栏可以点小三角隐藏,获得更大可视区域。

  3、使用列表浏览,可以更高效查看信息。

  4、使用未读查看模式,每次阅读完所有感兴趣文章不要忘记点"全部标记为已读"。

  5、建议起始页设置为"所有条目",进入即可查看最新更新。

  6、添加订阅输入框,可以输入RSS地址,也可以输入关键词进行搜索。

  7、加注星标是收藏,喜欢是评分,共享是分享给关注你的人。

  8、几乎所有阅读器都支持导出OPML文件,你可以在Google Reader导入使用。

  新手最常犯的错误就是订阅著名门户网站的新闻,然后每天都会收到一大堆乱七八糟的更新,自己真正感兴趣的内容早已经被深深掩埋。所以新手不推荐订阅更新量大的RSS源,最好从自己喜欢的一些博客,小更新量让自己慢慢熟悉功能,然后再慢慢加入各种内容。内在的逻辑是订阅感兴趣的而不是知名的网站,往往他们能以更小的成本带给你感兴趣的内容;或者订阅那个资讯站点的细分RSS,例如你只关注某财经网站的股票。避开大而全的RSS订阅,例如门户、资讯类网站,它们每天数百条推送会塞爆你的未读列表,你要从中找到感兴趣的信息会花费太多额外时间。

  最重要的一点,遇到不喜欢的RSS源一定要果断退订,他们占据你宝贵的空间并且没有任何功能。

---------------------------------------------------------------

最后推荐一些不错的RSS源供参考,你可以直接搜索网站名,也可以直接添加我提供的RSS源地址。

Don’t Waste Money on a New Computer for College

http://www.crunchgear.com/2010/09/11/dont-waste-money-on-a-new-computer-for-college/

by Scott Merrill on September 11, 2010


Heading off to college? Here's my suggestion: buy a used laptop from Craigslist and installUbuntu onto it. Seriously. You don't need a new computer for college. If you're pursuing a liberal arts degree, you really don't need a brand new computer just to write all the papers you'll write. If you're pursuing an engineering degree, the chances are high that your department's computer labs are better than anything you can buy for yourself.

The value of computer labs should not be underestimated, even for liberal arts students. In addition to hopefully beefy hardware with properly installed and maintained software, there's a very important social component to using computer labs. This is not to say that's just an opportunity to watch lulz videos on YouTube with your pals, of course. The people you meet in your classes and your degree program are kindred souls, and you should get to know some of them. Whether it's a team project, or help with a tough assignment, or simply making smalltalk, the interactions you can have in the computer lab are an important component of the social college experience, and you should not avoid them by locking yourself in your dorm room to plug away on your fancy new workstation.

That janky old laptop you buy from Craigslist will not be as attractive a target for theft as a brand new computer. If it does get stolen, you won't be out as much cash. No, it won't be a speed demon, but what do you seriously plan to do with it? Type some papers, read some emails, Facebook, maybe watch some Internet pornography? It'll sit unobtrusively on your desk, under a pile of papers, until you need it. Even if the battery doesn't work, you can still lug it with you to plug in at the library or the coffee shop when you need a change of scenery.

You're not going to play games on your college laptop. Your roommate, or someone in your hall, will have an Xbox 360. Someone else will have a PS3, and there's a strong chance that there'll be a Wii somewhere, too. Make friends with these people and play their games. Save yourself the grief of soda spilled into your own precious gaming console. Save yourself the trouble of kicking people out of your room when they want to play RockBand every night during Finals Week. Take the time to learn a couple new card games, too: Euchre, Golf, whatever. Going old school — you know, without electricity — can be a fun and super portable way to enjoy games and meet new people, too.

You're also not going to use your used laptop as a media PC to stream movies in your room. Oh sure, you can, but you'll be watching those things alone: none of your friends are going to want to crowd around your 14″ laptop screen to watch anything. For more social viewing opportunities, rely on those friends with XBox 360s and PS3s and big TVs. You can, however, load up your laptop with MP3s so that you can rock out (with headphones on if you have a roommate) while cranking out that paper on Plato's Republic.

The used laptop you buy from Craigslist should be used to help you get some schoolwork done, and little else. Ubuntu provides everything you need. OpenOffice can open and save files in Microsoft Word format, so you'll have no real trouble integrating with most of the campus systems. In the event that your school uses a classroom management system like Blackboard or Desire2Learn, you may have the occasional situation that requires some goofy ActiveX control, or proprietary shim component. See the paragraph above about the computer lab.

Ubuntu will keep you safe from the Wild West that is a dorm network. You can be absolutely sure that a good many of the computers on the dorm network are compromised by malware. There's also a slim chance that some miscreant in your building fancies himself a hax0r, and will probe and poke at every device he or she can find. Your Ubuntu laptop will not easily become a victim, and it might even become a conversation starter.

  1. Download the latest version of Ubuntu and burn it to a CD.
  2. Search Craigslist for a decent, moderately priced used laptop.
  3. Buy that laptop.
  4. Boot that laptop from your Ubuntu CD and follow the instructions.
  5. Enjoy your college experience.

Meet open source robot

Robot
CALIFORNIA: A US company is out to transform the world of robotics with a formula that has helped make Facebook popular. Their bot uses open source code that will let it run third party applications. Willow Garage a Northern California company believes that third-party applications can do for robots what they did for the iPhone and the world's top online social networking service.

An open-source ross.org software platform along with a PR2 robot priced at $4,00,000 combine in a technology mix that lets software savants craft apps to make machines do their bidding.

Willow Garage began selling the robots on Tuesday in what it depicted as a step on the journey to the kinds of personal, affordable robots science fiction writers have long envisioned. "This is fundamentally going to change the pace of development," said co-director Keenan Wyrobek.

"It will be a couple of years before robots get priced down to being in the house, but this is an absolutely necessary step to get there." University of California, Berkeley, researchers that took part in a test phase got a PR2 to fold towels and match pairs of socks from the laundry.

Engineers at German company Bosch had one of the robots sorting and delivering mail to desks in an office. While students at the University of Pennsylvania had a PR2 "reading" music and playing songs by rock bands U2 and the Beatles using drums and an electric organ.

The PR2 is intended to spare researchers from wasting time, effort and resources on building their own robots from scratch. "Most of the people who want PR2 are software gurus; crazy good software developers that have some cool app in mind," Wyrobek said.

"We are opening the field to software developers like what happened in the smartphone space, or Facebook and all those social networks." PR2 moves about on wheels and has arms with changeable grips. It stands four feet 1.2 metres) tall but has a telescoping spine that lets it rise to 5.5 feet (1.6 metres). The machine also has an array of sensors.

"If you have some cool idea you want to develop, it gives you a good starting point," Wyrobek said. Proven leaders in the open-source software community can qualify for a reduced price of $2,80,000 dollars for a robot, according to Willow Garage.

Google Maps for Android gets GPS navigation for walking routes

http://www.downloadsquad.com/2010/09/09/google-maps-for-android-gets-gps-navigation-for-walking-routes/

Pedestrians might get exercise or save on gas, but they don't get the fancy turn-by-turn GPS directions that drivers do. Or, they didn't until Google decided to release Walking Navigation in Google Maps 4.5 for Android. Android users can now use GPS navigation in walking mode, getting suggestions for the best pedestrian routes Google knows about. This navigation mode isn't just a copy of driving mode, either. It's got pedestrian-friendly features like vibrating when you need to make a turn, and a map that turns as you do. Walking navigation also uses satellite imagery by default, to give you a better idea of where you are. You can also use the Street View smart navigation feature in the Google Maps search bar to decide which way to walk. This is a fantastic idea, although I'm sure there are still some kinks to work out. If you've got an Android device, we suggest you, well ... waaaalk this waaay!

Fact or Fiction? Top 8 Linux Myths Debunked

http://www.pcworld.com/businesscenter/article/205147/fact_or_fiction_top_8_linux_myths_debunked.html?tk=hp_new

If the idea of using Linux in your business is one that makes you nervous, chances are you've fallen prey to one or more of the many myths out there that are frequently disseminated by competing vendors such as Microsoft. After all, each Linux user means one less sale for such companies, so they have a powerful motivation to spread such FUD.

In fact, the ranks of businesses and government organizations using Linux grows every day, and for good reason: it's simply a good business choice. Let's take a look, then, at some of the top anxiety-causing myths and dispel them once and for all.

1. "It's Hard to Install"

Today, installing Linux is actually easier than installing Windows. Of course, most people don't install Windows themselves--rather, it comes preinstalled on their hardware, and that's an option with Linux too, if you're in the market for a new machine anyway.

If not, however, the best thing to do is first try out the distribution you're interested in via a Live CD or Live USB. Then, once you decide you like it, you can either install it in dual-boot fashion, so that both Linux and Windows are available to you all the time, or you can install Linux instead of Windows.

Either way, installation has become extremely simple over the years, particularly on distributions such as Ubuntu, Fedora, Linux Mint and openSUSE. Most include a step-by-step wizard and very easy-to-understand graphical tools; they also typically offer a way to automate the process. A full installation will probably take no more than 30 minutes, including basic apps.

2. "It's Just for Experts"

That Linux is more difficult to use than Windows and Macs is probably one of the most enduring and yet unjustified myths in existence today. It certainly used to be true--say, 10 years ago. Today, however, the inclusion of attractive graphical user interfaces and other usability improvements in many distributions means that even elementary school children can use Linux easily.

Now, server usage is a different story--just as it is under Windows, for example. And Linux won't be exactly the same as a Mac or Windows. But on the desktop, if you're used to the GUI of Windows or Mac OS X, you should have no trouble getting used to Linux. It's that simple.

3. "It's Free, So It Must Be Pirated"

Despite the growing use of free and open source software in governments and other organizations, some people still believe that any software that's free must be illegally copied. Fortunately, that's completely false. The notion of "taking" software off the Internet and then "tampering with it" for your own ends can strike litigation fears into the hearts of those unfamiliar with the concept, but fear not! Free and open source software is designed from the start to be free in cost as well as open to modification and improvement. That's how it works and gets better.

4. "There's No Support"

Vendors of proprietary software love to strike more fear into business users' hearts by painting a picture of the Linux user alone at sea, without anyone to ask for help. Once again, completely false!

First of all, every Linux distribution has an online community with excellent forums for getting help. There are also forums dedicated to small businesses and for newcomers in need of extra explanation. For those who want even more assurance, commercial Linux versions such as Red Hat Enterprise Linux and SUSE Linux Enterprise Desktop come with vendor support. It's entirely up to you which route to choose.

5. "It's Not Compatible"

There are very few instances of hardware and software remaining that can't be used with Linux. One of the operating system's many advantages, in fact, is that it's designed not to hog resources, and so doesn't require the latest, cutting-edge hardware. Most peripherals are compatible as well, particularly in distributions such as Ubuntu.

On the application side, it's also rare to find a problem. If there is something your business needs that can be run only on Windows, however, there are packages like Wine and Crossover Linux to make that happen. There are also countless comparable and Linux-friendly alternatives that can be easily installed, including all basic productivity packages.

6. "It's Less Secure"

Of all the myths perpetuated about Linux, I'd say this is the one with the least merit. The reality, in fact, is quite the reverse: Linux is far *more* secure than either Windows or Macs, as countless examples and security researchers such as Secunia have confirmed. In a nutshell, Linux's superior security derives from the way privileges are assigned, the fact that it's open to scrutiny by countless developers the world over, and the diversity of distributions in use.

Ever wonder why you've never heard of the Linux equivalent of Microsoft's "Patch Tuesday"? That's because there isn't one--it's not necessary. Neither is antivirus software. Strange but true.

7. "It's Not Reliable"

If you're using a Mac or Windows, it goes without saying that you are intimately familiar with crashes and downtime. Part of that is due to those systems' vulnerability to malware, but part is also simply inherent in the software. That's a big reason why Linux is used so heavily on servers--it almost never goes down. Imagine a day in the life of your business with no downtime!

8. "Its TCO Is Higher"

Last, but not least, proprietary vendors are notorious for trying to counter Linux's free price tag with vague fears about its "higher" total cost of operation in the long run. All I can say is, if that were true, why are so many governments and organizations around the globe turning to it in droves, particularly during the tough economic times we've had over the past few years?

There are also numerous studies confirming the financial benefits of Linux in a business setting, even with paid support. It's worth noting, too, that TCO doesn't explicitly capture the future costs that will be incurred by being locked in with a particular vendor.

Is Linux perfect? Of course not; no operating system is. Nor is it necessarily the best choice for every business. But don't let the myths hold you back.
