How to change Wordpress’ default username

Frank:
這篇文章提到修改 WordPress 預設帳號名稱的方法,原文也是圖文並茂,文章有點長。

步驟說穿了就很簡單:
  1. 使用 phpMyAdmin 登入資料庫。
  2. 在左方資料庫選單中,選取要更改的資料庫。
  3. 選擇左方的 wp_users 欄位。
  4. 點選右上方的「瀏覽」兩字。
  5. 把畫面往下拉,會看到 admin 的資料,看到一隻筆的圖示,按下去編輯它。
  6. 然後會看到欄位:user_login,型態: varchar(60) 後面的值就是 admin,在這裡改成自己想要的名字。
  7. 按下最下方的「執行」即可。
After each installation, Wordpress gives you a deafult “admin” username and a random password to login to your control panel. Try to login with them and access your profile by clicking the “Profile” link on the top right section of the page.
##CONTINUE##
Wordpress installation

Wordpress default login

The profile page displays your user information such as your username, e-mail, and login password. You can easily change the password, but what about that username? Why do we want to change it anyway? Well, having a username as common as “admin” is not quite secure, not to mention hundreds if not thousands of other Wordpress bloggers use it as their login too.

Default profile page

Unfortunately, Wordpress doesn’t make it possible to change the username from the control panel. Yes, it is visible but no, it is locked for editing. To change it, you’ll have to access the database and do it from there.

Here are the steps on how to change Wordpress’ default username:

1. Login to your host’s control panel and access the MySQL database

In your web host control panel, you’ll find a link that goes to the database administration. On that page you’ll find a link to phpMyAdmin. Go and click it. Some web hosts might even have the link to phpMyAdmin directly on the control panel’s front page. After clicking the link you may or may not be presented by a login form. Enter your database login information to continue.

Your can see your database information in the “wp-cofig.php” file located in the root directory of your Wordpress installation.

2. Open your Wordpress database tables

On the left side of the screen, you’ll see a list of database. Find and click your Wordpress database. After you clicked it, the page will display the database tables, which stores all information about your Wordpress blog. Find the table named “wp_users“. This table holds information about users; e-mails, passwords, and of course usernames!

After you’ve located it, you need to browse it’s content. Along the table’s row you’ll see a series of action icons. Find the one that reads Browse. You can usully hover your mouse over the icon to see what action it wil do. Click it. On the screenshot below, Browse is the first icon after “wp_users”.

Database home

3. Open and edit the username

After clicking the Browse action, the page will display all users registered to your blog. If you happen to be a single user or just installed Wordpress, there will be only one admin user row. In the row’s heading you will see the user ID and next to it the user_login. This is the information that we want to edit. To do that, click on the Edit icon. On the screenshot below, it is the one next to the trash icon.

Database - select admin

You will then enter the table edit screen. Find the field that reads user_login that change its value to whatever you want your username will be. For example, I changed it from ‘admin’ to ’simba’. After you’ve typed the new user_login, hit the Go button located at the bottom of the page.

Change user login

That’s it. You can test your new username by refreshing your profile page in your Wordpress control panel. It will bounce you back to the login screen with a big red box stating your session has expired.

使用 Local DNS cache 加快上網速度

Frank:
當時使用這篇文章所提供的程式,確實是想要看看能不能加快,不過可能現在網路都很快,所以感覺不太出來,這支程式後來變成我分析 DNS 的工具,裝上它,可以看出長上的網站有哪些,有許多意想不到的統計結果。(這裡也是僅擷取前面半段)

影響上網速度的因素很多:電腦本身的處理能力、頻寬大小、網站主機的能力、電路品質、ISP服務品質…等等。

大多數使用者所能做的努力,就是買好一點的電腦,還有多花點錢申請大一點的ADSL,更有經驗的人就是另外加上 Google Web Accelerator

通常努力到這個階段,上網的速度已經可以讓人滿意了。其他的,也無從努力起。

還可以更快嗎?答案是肯定的。因為上網的一連串動作中,DNS解析是最容易被忽略的一個關鍵。

DNS解析的目的,是將人類容易記憶的文字網址,轉換成ip位址,個人使用的電腦再依照查詢來的ip位址,在網海中找尋到相對應的主機,接著送出請求,再收下主機傳來的相關資料。

##CONTINUE##

看似簡單的動作,其實是一連串的複雜的查詢與電腦之間的連繫,只要其中一個環節耽誤了,就會影響上網的速度。

那既然有這麼多問題,直接在網址列打ip不就得了?

沒 錯,打ip位址是一個方法,不過,以常去的網站為例,比方說 www.hinet.net,ip是203.66.88.89 , tw.yahoo.com ,ip是 202.43.195.52 ,有多少人能記得?就算加入「書籤」或是「我的最愛」,當對方的ip有變動,這些「最愛」就變成「沒人愛」了。

所幸,網站主機的變動率不會很高,但是每次上網,TCP/IP的特性就是會重複去查詢DNS的解析,浪費時間,所以只要將這個重複的動作在電腦內完成,不再向遠方的DNS主機要求,就可以提高上網的速度,於是 Locas DNS cache 的概念應運而生。

Local DSN cache 的概念在 Unix like 的系統上,早就是很成熟的機制了。WINDOWS 上除了有架設DNS SERVER的機器之外,並沒有 DNS cache 的服務。(要說完全沒有也不盡然,有個指令 ipconfig /flushdns 就是清除DNS快取,但是說有這個快取服務,偏偏又感受不到它的存在。)

廢話講完了,開始說說怎麼使用 FastCache 加速上網。

Local DNS cache 是一個概念,使用的軟體是 FastCache,官方網站有說明。下載在 http://www.analogx.com/files/fci.exe

檔案只有179k,下載完成後依說明安裝。

PCMan 教你幾分鐘內學會架簡易個人 FTP 站,和好友分享檔案

Frank:
這篇文章我只列出了前半段,其實這篇文章主要是介紹一個 FTP 軟體,免安裝的特性是最重要的,解開馬上就能用,解決了我兩台電腦之間的傳檔問題。
千萬要給自己一個機會嘗試,相信我,這真的很簡單。

隨著電腦和網路的普及,對於一般個人來說,尤其是使用學術網路的學生,架設FTP站已經是很普遍的事情。再加上作業系統的進步,還有網路上各式各樣的軟體,架設 FTP 站再也不是少數高手的專利。

硬碟容量越來越大,資料越來越多,電腦裡滿滿的寶藏,要是能和大家分享該多好呢,但很多人不熟悉電腦操作,也不想花時間學習,因而卻步不前,這是很可惜的,其實如果是在Windows系統下,這只需要短短幾分鐘時間就能學會。
##CONTINUE##
在Windows環境下,以前只有需要付費的少數外國軟體可以使用,不好操作又有一些中文不相容的問題,後來隨著軟體的發展,漸漸的各式軟體如雨後春筍般出現,百家爭鳴,各有所長,其中有幾套還是免費軟體,品質都很不錯,但很可惜,英文的介面配上較為複雜的設定方式,對於電腦初學者來說還是一看就打退堂鼓,會架 FTP 站的人相對還是少數,雖然其實很簡單,但因為大家都沒接觸過,所以會架站的人總不免有點得意,不會架的還得看人臉色拜託人家教,使用Serv-U等老牌軟體架 FTP 站也成為某些社團必教的課程。

其實,沒有那麼難,也不用花時間研究那些英文軟體怎麼用,我現在提供一個 Step by Step 的教學,按照以下步驟,在幾分鐘內一個不熟電腦的初學者都可以瞬間把個人 FTP 站架好。
快速簡易 FTP 站架設全攻略,Step by Step 示範,一學就會:

首先下載要用來架設 FTP 站的軟體,這裡我推薦我設計的軟體 PCMan's FTP Server (按這裡下載),這是專門針對初學者設計的全中文免費 FTP 架站軟體,特色是讓不熟電腦的人也能夠輕易架設 FTP 站。

R.I.P. - A tribute to web 1.0

Frank:
這篇文章寫了幾個過去我常用的服務,現在回想起來,好像還真有那麼一回事。
(原始位址那邊含有圖片比較完整)

A millennium ago the web was made of static websites with flashy ‘Click Here’ .gif files optimized for windows 95 on a 36k modem. These sites had no AJAX techniques, profiles, blogs, let alone an option to comment. The internet was a place to look around, instead of interaction.
##CONTINUE##
Now – a whopping 61,352 hours later – it’s hard to believe on how we could spend our time online without updating our profiles, downloading the newest Prison Break episode, uploading Flickr photo’s, filling our ipod with iTunes songs and reading the latest Google news.

Let’s go back into history and check out what happened to the websites that were ‘hot’ back then. Are there still pieces alive of the old web, or have these sites become an useless appendix?

In ’95 Hotmail was introduced: the first place to get a free email address, disconnected from an ISP.

Hotmail was properly the first contact for many new web users with the powers of the internet: communicating by email. Four years later after it's introduction 30 million people worldwide were exchanging @hotmail email addresses. At some point maybe thought to be the only way to ‘email’ by n00bs.

Hotmail was bought by Microsoft in 1998 for just 400 million dollars, a bargain for pre-internet bubble standards.
Now in 2007 the end of Hotmail is near – although the @hotmail.com won’t go anywhere- since it’s transformation to “Live” mail to become an integrated part of the Microsoft’s “Live” family.


geocities
Geocities was the most popular place where you could create your own free homepage on the web.

In 1997 Geocities was the fifth most popular website, with over 500,000 homepages created. Yahoo bought Geocities two years later for $3.57 billion dollars. And started to actively commercialize the homepages with various advertising types that resulted in their death sentence. With ‘real’ web hosting becoming affordable for anybody, the need for free homepages in this form vanished. Geocities accounts are now only used for outdated information, and to upload/download illegal mp3 files from...


Altavista
Search engine Altavista was the Google of the last millennium. The first real effort to index the World Wide Web. It was popular because it was one of the few search engines that actually came up with good search results.

But Altavista had a hard time fighting spam listings in their results.
While spam grew logarithmic in Altavista, some company named Google found a way to prioritize web pages more intelligently, and thus keep spam out better.
When people tried Google and compared it was Altavista, it became an easy switch. Since then their market share in the industry dropped to almost nothing, with only visitors from old bookmarks. Altavista never (tried to) recover. Yahoo! is now the proud owner of this piece of history.


ICQ
ICQ – for the younger people a abbreviation of “I seek you” – created in 1996 was an easy to use instant messenger program where you could add friends to your list, and see if they were online. Doens't sound new at all, but back then it was revolutionary for the masses and it became the ‘application’ everybody had installed.

ICQ was acquired by AOL in June 1998 for a whopping $287 million plus contingent payments of up to $120 million over three years based on growth performance levels.

What went wrong? Eventually the program got too many additional features that made the application heavy and unorganized. While competition of AOL IM, Yahoo IM, and MSN Messenger increased, and friends on your ICQ-list left the application. Eventually resulting in a mass abandoning of the network.


Netscape
Netscape, now only famous for the oldschool “optimized for Netscape” on outdated webpages, has dropped from a browser share of over 50% in ’98 to less than 1% now.

What went wrong? Netscape was ‘victim’ of Microsoft’s notorious ways of dealing with competitors. But in the end most blame lies with Netscape self, due to lack of innovation and inability to tie customers to their product. The Netscape browser was good in the beginning but got Slowwww, buggy, and had an (even more) ugly layout compared to Internet Explorer.

Struggeling to survice Netscape became in 2006 a non-innovative boring web portal, waiting to completely dissapear into the history books.


Realplayer
Bringing a online standard in streaming audio since ’95. The first audio from the web was transmitted in the Realplayer format. This was in a time of .wav files and slow 36k modems: not a good combination. Real had created the solution with their applications, and (live) internet broadcasts was born.

But what went wrong? The Realplayer audio format – and player - became obsolete due to - locally savable - small sized mp3 files, and Windows Media Player – distributed standard on all pc’s. Yes, the death story resembles Netscape Vs. Internet Explorer. Also the program became too commercial with annoying ‘buy pro version’ pop-ups every 10 minutes.


Network
The web hasn’t always been on ‘open’ place. In the previous millennium there was only one company available where you could buy a .com, .net or .org domain.
For the small ( rolleyes ) price of 100 dollars and a two year minimum, you would get your own domain name. But back then there was still a big chance you would be able to buy a dictionairy word as .com.
It took until the beginning of 2000 until they lost the monopoly position and domain prices dropped over 95%.
Since then innovation halted and Network Solutions became one of the thousands anonymous domain registrars.
