My campus lab has the Dell desktops. I am not sure the model, but the network devices are Broadcom BCM43228. As a result, after installation of the Ubuntu (they were not installed by me), Ubuntu cannot get WiFi connection to online.

Since my student mentioned that Windows can use the ethernet cable to share the wireless network, I asked him to help to share the wireless network from Windows on the other Dell desktop, and connect to the target Dell desktop.

Recently, I feel fervent to learn functional programming, because i) (in my opinion), it will become a trend, and ii) the interpreter can be used as an advanced calculator.

Since I am teaching Statistics, I want to do some calculation of the normal distribution probability.

Before I begin, I need to mention, in order to calculate the normal distribution probability something like P(x < X), this can be done by using a spreadsheet software with NORMDIST() and NORM.INV() for the inverse of the former function.

Recently I move back to use my (around) 4 years old laptop, HP Pavilion dv3. It has NVIDIA graphic card. But since I (re-)installed Arch Linux 64 bit on it, I failed to run the X11 with the proprietary NVIDIA driver. As a result, I used the Nouveau module instead. Then, I tried several times and finally successfully run the X11 with NVIDIA driver.

To use the Nouveau module, in the mkinitcpio.conf, we have to add in “nouveau” module, then build the initramfs (refer to wiki page). And use the “Xorg -configure” to generate the xorg.conf.

Today I just upgraded the MIUI to version 7. Actually, it prompted for the  upgrade since some times last week. But I failed to upgrade, expected to be server problem.

So, today I determined to find the solution for manual upgrade. The upgrade version is MIUI 7.0.5.0. I visited the official site and searched the ROM, but the official site does not have this ROM. As a result, just did a search, and found the target ROM in the MIUI official forum. Then everything becomes easy now.

Previously I read an article regarding JavaScript and another one regarding HTML.

JavaScript, it is so wonderful that not only enhances the HTML interaction, (e.g. jQuery), it also makes a revolution of the system architecture design (e.g. AngularJS, ReactJS with Babel). The Babel JavaScript compiler is so amazing that it can transform the JavaScript to EcmaScript 6 with JSX feature. JSX is actually cannot be interpreted by our current web browser, but with the Babel, it makes JSX possible.

I am not a Facebook fervent user. I use it because of some of my friends are using it.

So, if you want to enable your “available to chat” status to your group of close friends or special group of friends,

1. Go to Friends an create a list that you want to chat with.
2. After creating the list, add your close friends.
3. Now, turn on the Chat.
4. Go to Chat Options > Advanced Settings
5. Choose “Turn off chat for all friends except…”, and add in your target chat.

Preface

LibreOffice Writer is better than Microsoft Word. If you are a web developer, you should understand that there are class and style. Using LibreOffice is tended to using class-like style, instead of direct formatting, which causes a lot of inconsistent, troublesome, and time consuming modification throughout the word processing. And this is happened when the newbies are using Microsoft Word to create templates for the advanced user like me, and causes me full of trouble as being tortured.

I like science fiction movie, especially related to time travelling. Watched Project Almanac (2015), and there are quite a lot of interesting points.

[WARNING! CONTAINS SPOILERS]

Firstly, unlike Back to the Future (1985), time travellers going back will not meet the time travellers selves, this can be seen when the protagonist and the friends solve Quinn’s chemistry problem. Secondly, unlike Time Traveler’s Wife (2009), travelling to the past can change the future; yet in Time Traveler’s Wife the timeline is fixed, there is only one, single, timeline.

This is not a new stuff. You can get some tutorials from Internet. And it is very interesting when I did this, because I learnt new things. The following procedures are based on what I remembered. So, it may not be 100% accurate, since I am a forgetful person. 😅

What I did was reading the Arch Linux Wiki page. Then, followed the instructions as much as possible, and do some trials and errors. Remember to backup everything necessary. And try this at your own risk.

Personal Web Server(?) age

When I was doing web development, that time was mostly static pages, with no CSS, a little JavaScript. The only interaction was CGI form. Then I learnt VBScript for ASP and Microsoft Access and used Personal Web Server.

Designing page layout was like hell, everything was using table. The font style was hard coded. So, the HTML source is too messy.

LAMP age

Then, from Personal Web Server, the web server was upgraded to IIS. Next was XAMPP on Windows, using all open source solutions: Apache, MySQL, and PHP. That was a great solution. Unlike ASP, PHP has more functions, more libraries, supports object oriented, syntax similar to C and C++.
