http://www.webupd8.org/2011/02/attack-of-clones-is-very-interesting.html

Attack Of The Clones is yet another theme created by JurialMunkey (who is also behind Divergence IV: A New Hope) that features a unique Metacity theme and a very interesting combination of light and dark colors.

Attack Of The Clones requires Murrine Engine 0.98 (which is available in Ubuntu 10.10) - if you're using Ubuntu 10.04, install it using the following commands:

 sudo add-apt-repository ppa:elementaryart/elementarydesktop sudo apt-get update sudo apt-get install gtk2-engines-murrine

To install the theme, download the .zip, extract it, then open the "Appearance Preferences", switch to the "Themes" tab and drag and drop the extracted .tar.gz file onto it.

80 Essential iPhone Apps for Small Business

Mobile Download Guide: 80 Essential iPhone Apps for Small Business By James Alan Miller January 28, 2011

The ever-expanding smartphone and mobile application market, as with the economy at large, depends on the support of small business to keep the engine of growth running smoothly. You could say--as we often hear from politicians regarding the country in general---America's legion of small, privately-owned companies are the foundation upon which the continued success of the wireless sector stands.

For Apple, it may have been consumers that first launched the iPhone into the stratosphere, but it is Steve Jobs and company's flagship product's growing adoption by business, particularly the millions of smaller ones, that will keep it, if not on top--Google's Android platform is quickly catching up and RIM's BlackBerry isn't going anywhere--then near the summit of today's unprecedented mobile device boom.

Like other mobile device manufacturers and software developers, Apple knows this of course. It would be imprudent, if not downright foolish of them to ignore the combined buying power of small businesses. That's why so many vendors in the wireless sector, Apple included, take the mobile computing needs of smaller companies so seriously when developing new products and marketing plans. And it is one reason why the 300,000-strong App Store contains tens of thousands of applications capable of helping the owners and employees of proverbial mom-and-pop establishments run their companies and get the most out of their iPhones--whether or not the apps in question were even targeted in their direction in the first place.

In this article, we've done the heavily lifting to help you decide what apps to install on your iPhone(s). We have sifted through the App Store with a fine tooth comb, distilling our list down to 80 essentials. As with previous articles in our series on great iPhone apps, every program listed below won't meet the needs of every small business operator, of course. They simply can't.

After all, as it sometimes appears, there are nearly as many different types of small businesses (i.e. medical and legal practices, accountants, dry cleaners, pharmacies, coffee houses, independent booksellers, restaurants, decorators, retail stores, franchises, etc.) as people running them, with each type and sub-type--let alone individual owners and employees--having their own unique mobile requirements. Most readers will find plenty of applications to help them better perform the mobile (and not so mobile) tasks at hand, however.

Johns Hopkins University Selects Likewise to Manage Linux and Mac

http://www.globenewswire.com/newsroom/news.html?d=211676

BELLEVUE, Wash., Jan. 26, 2011 (GLOBE NEWSWIRE) -- Likewise, an expert in helping businesses and educational institutions manage cross-platform IT environments, announced today that Johns Hopkins University will use Likewise Enterprise for Education to integrate its Linux and Mac computers using Microsoft Active Directory.

Johns Hopkins University is a private research university based in Baltimore, Maryland that maintains campuses in Maryland, Washington, D.C., Italy, China and Singapore.

"Although educational institutions use the same technology as enterprises, the policies, procurement procedures and security concerns differ greatly," said Arne Gallagher, director of worldwide education sales at Likewise. "Johns Hopkins has an incredibly complex, diverse and distributed IT infrastructure and our Likewise Enterprise for Education delivers true cross-platform harmony."

The competitive pricing of Likewise Enterprise for Education, along with volume discounts, helped Johns Hopkins achieve cost savings.

Johns Hopkins agreed to a two-year site license that allows the decentralized campus flexibility to use the technology wherever it is needed. The central IT department can enable single sign-on and enforce policies on systems in the network, and will also manage computer labs comprised exclusively of Macs using Apple's Workgroup Manager application and Likewise Enterprise, which allows Mac-specific system settings to be managed remotely.

"Likewise Enterprise will allow us to manage our vast campus network centrally using Active Directory," said Kyle Reynolds, IT manager at the Institute for Computational Medicine at Johns Hopkins University. "The savings we will achieve by reducing operating costs and eliminating additional hardware required by other solutions adds to the value we're getting from Likewise. After examining the alternatives available, Likewise Enterprise for Education was the clear choice."

About Likewise

Likewise provides integration and identity management solutions to improve security and operational efficiencies and to help achieve regulatory compliance in mixed networks. Likewise Open lets organizations securely authenticate Linux, Unix and Mac users with Microsoft Active Directory. Likewise Enterprise includes all the core authentication technology that comes with Likewise Open, plus world-class migration, group policy, auditing and reporting modules.

Switching to Desktop Linux? 6 Ways to Ease the Migration

http://www.pcworld.com/businesscenter/article/217836/switching_to_desktop_linux_6_ways_to_ease_the_migration.html

- PCWorld Business Center

By Katherine Noyes, PCWorld

With all the many compelling reasons for a company to switch to Linux on the desktop, it's no wonder that businesses large and small are increasingly relying on the free and open source operating system. After all, it's free, flexible, reliable, and highly secure--to name just a few of the most attractive features.

No matter how good your reasons for switching from Windows to Linux, however, the fact remains that most of us don't like change. That--more than anything else--is why migrations of any kind can be painful.

One of the most commonmistakes new desktop Linux users make is to give up too easily, often citing the frequently heard myth that "It's too hard." The truth, however, is that it's just different. It may be difficult to remember at this point, but Windows took some getting used to, too.

How can you make the desktop Linux migration process as easy as possible in your business? Here are a few suggestions.

1. Get Buy-In at the Top

This probably goes without saying, but executive buy-in is essential to business migrations of just about any kind. Users need to know that the change has been mandated from the top or they won't feel motivated to go along with it.

2. Choose the Right Distribution

Before the migration even begins, it's critical that you choose the right Linux distribution from among the many hundreds that are out there. As I've outlined before, this is primarily a question of the skills of your users, the focus of your business, your hardware and software needs, and the kind of support you hope to get.

Assuming your users haven't been on desktop Linux before, I'd be inclined to steer you toward either Ubuntu or Linux Mint, unless you have compelling reasons to do otherwise. To help convert real Windows aficionados, there's also Zorin OS, which is designed to mimic Microsoft's graphical user interface. You should definitely avoid some of the more expert-oriented distros such as Arch Linux or Slackware.

If you want a little extra online help in making your decision, check out the zegenie Studios Linux Distribution Chooser or polishlinux.org's distro chooser, both of which can be useful.

3. Choose a Familiar Desktop

One of the nicest things about Linux is that it's so flexible and customizable, and that's particularly useful when it comes to introducing new users to the operating system. In addition to choosing your distribution carefully, I'd also encourage you at least to check out a few different desktop environments.

I outlined a few of these not long ago within the context of Ubuntu--which has traditionally come with GNOME by default--and there are many more. Pick one that seems relatively similar to what your users are familiar with.

4. Begin with Key Apps

Because so many of the apps your employees will likely need are cross-platform, one good hurdle to jump ahead of time is getting them used to any new key applications. If they're used to Internet Explorer, for example, you can start them on Firefox or Chrome while they're still on Windows.

If they've been using Microsoft Office, you can get them used toOpenOffice.org or LibreOffice ahead of time, too. That way, when it comes time to make the switch in operating systems, they'll have some familiar territory--it won't all be new.

5. Remove the Pressure

Before you're aiming to make the switch, set up a Linux box in your office using the distribution, desktop and apps you've chosen. Make sure there are some games on there too, and offer it as an option for break time. There's nothing like no-pressure time with a new technology to make people open-minded and quick to learn.

6. Make a Cheat Sheet

Because the lion's share of any difficulty in switching to Linux is simply getting used to something different, it can be a real help for users if you give them a quick, post-training "cheat sheet" to remind them how to get at the tools they need once the switch is made.

It could be worded like, "Instead of... (Internet Explorer, for example) Use... (Firefox, say)." It could also outline the first few clicks to get users where they need to go. They'll probably be fine once they're in the applications they need--more often than not, it will simply be the process of getting there that they need help remembering.

There are, of course, outside consultants and other resources that can be used to help with this kind of migration. There are even several books on Amazon (such as this one) dedicated to helping with the process. With a little preparation, training and thoughtful choice, however, pain really shouldn't be part of the picture.

中国联通定制3G手机可以在美国用吗？

中国联通定制3G手机可以在美国用吗？

买的是中国联通定制的夏普3G手机，请问插上美国的sim卡后可以在当地使用吗？ 还有就是能否使用当地电信的3G服务？美国的3G制式是 wcdma ,中国联通也是wcdma,这是否意味这手机也能在美国用当地的3G网络服务？谢谢 ^ ^

问题补充：

GSM三频能用，那么wcdma 3G办好sim卡后能不能在美国用呢？

最佳答案

 中国联通定制的夏普3G手机应该可以插美国的sim卡在当地使用， 中国联通的手机大多没有网络锁， 反之美国的拿到中国就不一定能直接用了，美国营运商大多都设了网络锁！ GSM三频指850M 900M 1800M三个频率，中国不用850M北美地区才有，联通卡在美国可以用但漫游费太贵！

 
  中国移动,中国联通,中国电信的3G频段分别是什么?

 
 中国移动获得的频段是1880-1900MHz和2010-2025MHz； 中国电信获得的频段是1920-1935MHz和2110-2125MHz； 中国联通获得的频段是1940-1955MHz和2130-2145MHz。

 
  中国移动、中国电信、中国联通的2G、3G分别采用哪些网络制式？分别是哪些号段？

 
 移动 联通的 2G是GSM 电信的2G是CDMA
 移动的3G td-cdma  联通的3G WCDMA 电信的3G CDMA2000

 
 移动号段。134[0到9]。135、136、137、138、139、150、151、152、157、158、159、【187、188、147这几个属于3G专用号段】  电信 133 153 189 联通 130 131 132 156

Backup Your Ecommerce Website - or Kiss It Goodbye

http://www.ecommerce-guide.com//article.php/3921071

— eCommerce-Guide.com

By Helen Bradley
January 18, 2011

Your small business ecommerce website is a valuable asset. Every hour that you spend adding content is an investment in your business, but it's an investment that could be wiped out in an instant. If that happens you could be faced with rebuilding your small business ecommerce website from scratch, and that's often such a daunting task that many business owners opt to walk away from the business instead.

In this column, I'll explain the risks, show you why ignorance is not an option, and how you can protect your investment in your small business website by ensuring that adequate data backup process are in place.

Small Business Ecommerce Website Security Risks

One slip of a finger by a disgruntled employee, or by your own carelessness, could delete your website. Your site's also at risk if the hard disk it's stored on crashes, or if the building that hosts your server is damaged by fire or natural disaster. And if the company that hosts your site goes out of business, well, you're pretty much out of luck there, too.

In any of these situations your website will go offline -- only the largest of businesses can afford to have a fully redundant system where a second machine in a different location can take over without significant delay. For most small business websites, a disaster will take your site offline for a substantial length of time if not for good.

Who's Got Your Back(up)?

If your site goes down for any reason, the question then becomes "How do you get it back online again?" If you have a recent data backup and if your programs are backed up then, with time, effort, expertise and dollars your website can be re-built and made fully operational again. It won't be easy but it is possible. However to do it, you need a backup, and it has to be a backup of everything. It has to be recent, and it has to be undamaged.

Whether or not you have what you need depends on who is doing your data backups, whether they're doing their job and if the backup they do includes everything that you need.

If you purchased a Web hosting service, and you're assuming your hosting service is attending to your data security needs, then that assumption could cost you your business. Ask your Web hosting service if it's performing regular backups. Ask what specifically its backing up, where the backups it stores and how many it keeps.

You also need to ask what sort of assistance will be available if you have to recover your site from those backups. If your hosting service cannot or won't answer these questions, you have cause for concern.

Small Business Ecommerce: Disaster Recovery

You need this information from your Web host provider because a backup to a duplicate drive on the same server won't save your website in the case of fire or natural disaster. At least one backup should be stored off site and well away from the server itself.

If your hosting service doesn't backup your shopping cart software and customizations, your product data and images, your email data, mailing lists and SSL certificates, then the absence of any one of these could cost you your business. For example, your email mailing list took years to build and, if you lose it, you won't be able to contact your customers. Your product details and images, sales data and historical record are all key parts of your website. If they aren't backed up, you won't be able to recreate them easily, if at all.

The number and frequency of the backups is important in case your system becomes corrupted or infected with a virus. If you have only backup, by the time you realize you have problems, it too might be corrupt or infected. Retaining a series of backups from different dates gives you a better chance of having a clean backup to restore from.

Small Business Ecommerce: Web Host Failure

If your Web-hosting service goes out of business, not only will your website go down but you may not be able to access any backups that your hosting service made. To protect against this, you should have a second backup, which could be one you do yourself using a FTP (File Transfer Protocol) program to make a copy of your server files onto your own computers. There are also online services that will, for a fee, perform an online backup to copy your shopping cart and data to a second location that's not controlled by your hosting service.

Unfortunately, creating a data backup system and ensuring it works is something that's often left undone because it isn't a money earner. You won't see any immediate return from spending time organizing backups today, but tomorrow those backups could be the difference between being in business and not.

Smart business professionals don't go without data backup. To ensure you won't be kissing your small business ecommerce website goodbye if it crashes, make sure that it is backed up regularly, and that at least one backup copy is under your control.

 Rogers 是加拿大最大的GSM无线电话商, 用的是GSM 850MHZ 和 GSM 1900 MHZ,    FIDO 一年前已经被 ROGERS 收购, 用的是 GSM 1900MHZ.      TELUS 和 BELL 都是 CDMA 网络, 手机没有 SIM 卡也没有 USM 卡的.       中国的手机如果要保证在加拿大能用至少要有 1900MHZ, 如果没有 850MHZ, 在地下停车场\隧道\电梯间会接收不到信号, 所以建议最好用四频手机.       中国的手机大多是两频或者三频, 低端手机里面四频的比较少见, 智能手机比如 HP iPAQ6515/6955 \Treo 650/750 Blackberry 7100/8700/8100/8800 HTC s620 都是四频的...      加拿大的 Rogers 不用 WCDMA/CDMA2000, Rogers 的 3.5G 手机是 HSDPA, 所以不要买中国或者香港的 3G 手机到这边用(用不上,浪费)      如果要用 email 的话建议买带有 Wifi (802.11 b/g) 的手机, 有急用的话在有免费wifi的地方就可以收发电邮      加拿大的本地手机很少有中文(不排除海外水货有), 所以不喜欢用英文机最好还是自己带.         加拿大的手机服务相对比较便宜, 一般接听免费(国内所谓的单向收费)的计划是 $25~35, 加上$6~8的牌照费, 911费, 来电显示费...一般月租在 $30~50, 如果签上3年的合同就可以拿商家送的手机   所谓的合同就是卖身契, 每个月用要给钱不用也要给钱是也.    如果签了最低的约, 比如$20每月, 加上杂费和税之后每月支出如果按照 $37算, 一年就是 $37 x 12 = $444, 三年就是 $1332.    如果不超支, 基本上就是那么多. 所以回头看送手机只不过是服务商的揽客手段之一.
