There are three items. All are running on my desktop now.

  • Western Digitial Caviar Blue 1TB (HDD)
  • AMD A8-3870K Black APU Quad Core Processor and MSI A55M-P33 mATX FM! Motherboard (MoBo CPU bundle)

5 Twitter Tips for Newbies in 2014

Twitter is one of the best, if not the only best, social networking web site. Covering most countries in the world. As a newbie on Twitter, what is the basic tips?

I have my Five tips for newbies in 2014.

1) Complete your Profile

Of course, you should have a twitter account. If you don’t have it, just register one on Twitter web site.

When you have your account, sign in and click the right gear icon on the top navigation banner. Then, click Edit Profile.

Twitter Profile
Twitter Account Profile

You’d better to complete all information on this page.  Such as photo, header, website URL, Bio. The URL in the Bio will automatically be click-able link.

They will be shown on the Profile summary page, when people search you. Very important.

2) How to use Search

A good search tool has same features. User friendly.

Easy to search other users; easy to search event; easy to search tweets.

Twitter has it own search, powerfully.

For example, I input “Global” in the search box. Twitter provides auto-suggestion terms in the pull-down list. You can find some just a suggested keywords, some with avatar are users. And sometimes it will show you some terms with hashtag #, it is used to search tagged content. These search functions are very helpful. User does not have to think how to input the search terms in the search box.


There are some search tips for you:

  • Search keywords exactly: put two or three words inside of quote.
  • Search either one of two words: put or in the middle of two words.
  • Do not include one word in the search results: put the minus sign in front of this word.

3) Check the hot topic, or Twitter trends

It is the official tool, go to

Twitter Search Home

Above is the Trends when I sign in my account. The trends is provided based on my account, history, or the people I follow.

You can also see Worldwide Trends, if you are not sign in. It is interesting to see what people focused in other places.

twitter search home worldwide


4) Use twitter desktop application

Twitter did not have good web interface previously. It changed or upgraded many time. Now it is better. But somebody still want to use third-party desktop tool, just like me. Most of time I use MetroTwit. There are some choice for you, tweetdesk (now it is by twitter), MetroTwit, hootsuite, janetter. You can try to install every each desktop tool and try at least one or two days. Then make your choice.

5) Figure out who is influential on Twitter

Just see who has the most followers. But don’t worry about it. Twitter automatically recommends followees for new accounts. There are also some websites provide the service. Go to following web site and see if it is interesting. If you like it, just follow them. Then you will have something on your timeline.

The basic Five tips for newbies. Start to use Twitter and find interesting people and event.


Use MetroTwit as my twitter tool on desktop

I used twhirl for two years. Now I have to say it is not the best one any more. I googled it and find MetroTwit.

I feel the look of it is simple and clear. I like it. Users can custimize the layout. From two columns to three or four columns. It can conain my own timeline, mentions, favorites and etc. Skins or themes are changable. And also notification system included.

Firstly, Drawing inspiration from Microsoft’s Metro design language, MetroTwit celebrates an elegant and clean user interface that’s beautiful to look at and a pleasure to read. I use the larger text to shown the content. I put the window in full screen on my second monitor.

Secondly, Taking advantage of the latest Microsoft .NET 4.0 and Windows Presentation Foundation 4 frameworks, MetroTwit is a first-class native application that shines on Windows. Yes, I have to install .NET 4.0 before install it.

How to add windows to a CentOS 6.3 server

I installed a CentOS 6.3 server on virtualbox. It has no windows, or GUI installed.
Now I wanted to add a GUI to my server, but I could not find easy documentation showing how to add a GUI, or Gnome in this case, to a CentOS 6 server installation.
There are a lot of results of how to do this, but things have been renamed in CentOS 6, so that made it more difficult to figure out. Also, there are “Short Names” and I am assuming they are called “Long Names” associated with a yum groupinstall, which added to my confusion.
To add Gnome/GUI to a minimal CentOS 6 install run (short name version):

yum groupinstall basic-desktop desktop-platform x11 fonts

And the “long name” version:

yum groupinstall "Desktop" "Desktop Platform" "X Window System" "Fonts"

Install XP SP3 on Compaq Presario SR1520nx

I tried to install SP3 on my wife’s Compaq desktop. It has Windows XP Home Edition.
In the first time. I installed SP3 within the Windows Updates. When it restarted after the installation, it did not boot normally. It failed and auto-rebooted, then stay in the boot menu.
I can boot in the Safe Mode.
So I remove the SP3 and downgrade it in Safe mode.
I don’t know what’s wrong with SP3 or this Compaq.
Later I Googled a guide tell me the problem is created by HP (Compaq).

First problem, affecting AMD-based computers with OEM images, primarily HP Desktops

Just like Compaq Presario SR1520nx. It has AMD Sempron 1.8 GHz CPU and SIS chipset.
To double check the problem, do the following steps.
You may not see the error code because the computer reboots too fast. ( Just like me)To force the computer to stop when it crashes, you need to set an option during startup. To do so, hit the F8 key during restart right when you see the black Windows XP screen come up. Then select the “Disable automatic restart on system failure” option, as shown below:
