1U server – AM1H-ITX 5350 build

October 28, 2014 8:25 pm

Just finished building a 1U ITX server for home router, web and email server with AM1.

Case: X-Case ITX 19-02 – 1U Rackmount
Mobo: Asrock AM1H-ITX
APU: AMD Athlon 5350 (Asrock “Cool’n’Quiet” using powernow-k8 driver)
Heatsink: FM2+ heatsink Gelid Slim Silence AM1
PSU: DLH 90W Ultra Slim Travel Laptop Power Supply
RAM: 1600MHz 2x4GB @ 1.325V
HDD: 2 x 500GB 2.5″ HDD
NIC: HP NC360T

AM1H-ITX 1U server build

Did have a problem with the install, Proxmox 3.3 won’t directly from a USB disk and needed to install it on to the HDD from a different computer first. Proxmox working properly with the following VM:

  • Sophos UTM Home Edition 9.2 VyOS – KVM
  • Debian 6 turnkey lamp – OpenVZ LXC
  • Ubuntu 13.04-x86_64 – OpenVZ LXC
  • Zimbra Open Source Edition 8.5 – OpenVZ LXC

First time trying out Sophos UTM and really like it, definitely one of the best if not the best UTM (home router) I’ve used so far. Still a problem with the upload speed, possibly with the KVM virtio NIC driver. I’ve already disabled TSO and GSO with ethtool, but I can get 94Mbps download speed, but only around 45Mbps upload speed on a 100/100 fibre optic connection.

Also managed to get the Asrock “Coll ‘n’ Quiet” working with the powernow-k8 driver:

modprobe powernow-k8

vi /etc/modules
powernow-k8

vi /etc/default/cpufrequtils
GOVERNOR=”conservative”

Just a few things to improve on:

  • either adding a SSD or another HDD to making it into a raid-1
  • Cooling on the processor, perhaps by diverting more cool air to it. Currently the AM1 5350 does run quite hot at around 50℃ even with the FM2+ heatsink which is larger than the original AM1 heatsink.
  • Change to long ribbon cable for the dual gigabit NIC card to a proper 1u riser

Antec ISK 110 A88x FM2 mini-ITX build

May 2, 2014 9:45 am

The desktop I had was six years old so it was time to upgrade, I wanted something small and low power but has a decent inbuild graphics that can drive a 2560×1440 monitor over DVI-D. So, I decided on getting a ITX system with the AMD FM2 APU, was waiting for the A8 7600 to come out but that wasn’t out as early as expected, so went for A8 6500 instead.

Case: Antec ISK 110 Mini ITX
Mobo: Asrock FM2A88X-ITX+ @ NB 1.10V
APU: A8 6500 @ 1.125V
HS(F): Prolimatech samuel 17
Fan: Raijintek Aeolus Alpha 140mm
RAM: Crucial Ballistix Tactical 1866mhz 2x4GB @ 1.480V
SSD: Kingston HyperX 3K 120GB

Antec ISK 110 A88x ITX build

Build went well except the heatsink samuel 17 is a few millimeters too long and the ISK 110 can’t close. So I had to trim part of it off to get it to fit in the case.

Running at stock frequency with slight undervolting, temperature of system and APU idle at around 30°C.

Sony Reader eBook – Chinese

January 30, 2009 4:49 pm

There aren’t many eBook readers to choose from in the UK that comes with e-Ink 2 display and Chinese support, and many like the Sony PRS-505 that doesn’t support Chinese ebooks. Since it’s a Linux based device like many others people have made patches to enable Chinese on this reader. Thanks to them you can add Chinese support to your eBook reader! Just google “PRS-505 中文” and you will find there are at least 3 methods out there now that will allow you to do that, some require flashing the reader and some doesn’t. I went for the one which require flashing the device since I don’t have to activate the patch everytime you reboot, but it’s safer not to have to flash the reader!

This eBook reader is quite ideal if you have a lot of ebooks ready to be put on. This works out quite well for me because all the Buddhist materials/books are for freely available online! There are many websites for Buddhist books and sutras, here is one that I often visit:

To read them on your ebook, you can either upload them to the reader as plain text or use a multi-platform software called “Calibre” to convert your (html) files into .lrf or .epub. Here is how I convert the ebooks.

  1. Pick a book you want to convert, e.g. 淨土十疑論
  2. In your browser, save page as html only
  3. Drag this html file into Calibre and click convert
  4. Upload to the ebook

Problems that I experienced:

  • Automatic table of content creation in Calibre – It will created the table of content but failing to link it to the right page! But it’s good enough!
  • Reader freeze on connecting USB to computer – need to reset to solve this problem, I believe it’s a problem with the Chinese interface that I’m using which is probably solved by now. But my advice is to use the original English interface!

Here are some photos of the eBook.

LG Renoir – KC910

November 4, 2008 11:38 pm

My contract with Three UK ended 2 months ago, since I’m still quite happy with my K800i that I got 2 years ago, I thought I will just continue with the contract as what they’re charging me is quite reasonable (£10 per month). Last Sunday, they called me and asked if I want to upgrade my mobile, at the end I decided to get the LG Renoir. I surprised myself this time as I didn’t read any reviews before getting it, but since I am not intended to keep this phone for myself and they are charging me a one off £40 for it, I decided to get it.

The phone arrived today, it was packed in a very nice and a relatively small box, which is good because nowadays products tends to come with excessive packaging. My first thought was that this looks so much like the iPhone! I’m impressed by the phone, and here are some of the features that I like:

  • Wi-Fi – Can do without having a computer at home if all we need is checking email and some browsing…
  • GPS – Very useful for travelling especially when we are driving (not yet supported)
  • 8MP Camera – Since I’m using my K800i as my camera, this would be nice
  • 8GB SD card – Surprisingly it comes with that much memory, I can’t believe memory is getting so cheap nowadays!
  • Touch screen – I find touch screen a clever invention for human to interact with computers/machine, much more user friendly when implemented well.

There are also something that I think it can improve on:

  • GPS – only for geotagging at the moment, no software support for navigation
  • Speed – The interface can be slow at times
  • Touch screen – not quite sensitive enough, sometimes I’ve push it!
  • Application – As the phone is still quite new, many are not supported yet. The good thing is, most of the points mentioned here can be fixed in the next firmware.

All these features used to be what I want in a mobile, integrating everything that I need into one! It’s all nice to have, but none of these are necessary!

The world has changed so much, and our wanting never ends, so does our suffering. Often, we want something so much, and after much hard work, when we get it, how do we feel? Satisfy? Happy? May be for a moment, a very short moment! This phone remind me again that these materialistic things really doesn’t bring happiness, peace nor make us feel contented, all these are impermanence! After getting the object that we long wanted, moment later we often move on to wanting the next object, our wanting never ends! You may not agree with me, but try to ask yourself if these materialistic things give you long lasting happiness or does these wantings bring endless suffering.

On Sunday, I went to Amaravati Buddhist Monastery to join their Kathina ceremony this year. This is my third time attending this ceremony, the first time was in 2006. One of the points that I remember from the talk after the ceremony is that advertisements are decided to make us feel discontented! I found this very true myself, many advertisements often try to make us want more, make us feel unsatisfied and a feeling of lacking something, suggesting that buying their product would satisfy us.

Adverts are everywhere nowadays, even if we don’t watch TV, they are on websites, bus stops, train stations, you name it. Often we are not aware of what they are doing to us, no wonder why many of us always feel unsatisfy and wanting more all the time! I’m not blaming the companies for advertising here, it comes down to supply and demand again. If there is no demand, why would they advertise anymore. It’s ourself who is reasonable to watch our mind, as soon as we start blaming others, we are not doing ourself any good. I will share a quote from the Dhammapada (法句經):

 As a well covered house is not penetrated by a rain,  thus a well developed mind is not penetrated by passion.

如盖屋不密,必为雨漏浸,如是不修心,贪欲必漏入。

I still have a great interest in technology and it’s one of the things that I still do get affected by. I’ve to admit that I do like this phone, but I must watch my mind from wanting it! So I’ve decided to keep to my K800i as long as it lasts and not keeping the LG Renoir for myself. I still have much to work on!

Google Maps “My location” & Skype on K800i

July 14, 2008 7:50 pm

Google Maps Mobile – My location

If you want this function on K800i and found that it’s not supported after installing GMM, you will need to flash your phone with the latest firmware.

Google Mobile Maps (GMM) 2 recently introduce a new feature called “My location”, a function to find your current location using Mobile towers around for mobile without GPS. I’m surprise that my K800i from 2 years ago can run GMM, however to support this function the mobile need the latest firmware (at least not the one I have)!

I’ve version 2.2.0 installed and tried this function in Bracknell, I would say it’s not too bad. Most of the time it says it’s accurate to within 1.7km (probably better than it claims, I would say within 1km most of the time). However in places more urban the accuracy will be higher. I read somewhere that GMM uses data collected from mobiles with GPS, with increasing number of people using this function, it should get more accurate over time. The reason for finding out about this is mainly for travelling. GMM would be very useful in finding hostels, food and point of interests nearby…

Skype Mobile

Download the latest version from skype directly and it works fine on the K800i too but it’s not true VOIP. What it does is that it loaded up all the contacts and everything as expected, but when you make a call, it will dial a number (charged at local rate or deducted from inclusive minutes) to make that call. A bit like using a calling card I guess, but without entering the pins… So becasue of that I went on to searching for a true VOIP (SIP) client for K800i but couldn’t find one at this moment of time. However did found PennyTel which is slightly cheaper than skype and the good thing is, you can use any SIP phone or softphone like x-lite or ekiga in linux. Also the Skype that comes with 3’s X-series is actually a iSkoot, not Skype!

Three Roaming

Something that I only just found out, Three roaming is actually “free” with you are travelling in a country with a 3 sister network, ie. Austria, Australia, Denmark, Hong Kong, Italy, Ireland and Sweden. “Free” means you can use your inclusive allowance to call or text standard UK number + data allowance! However if you call a local number aboard, it will be charged as a oversea calls just like how it would be if you make the call from the UK!

Useful Appications

Software mentioned here are data intensive, unlimited internet access is recommended on your mobile!

If you are also on Three UK, you will find that 3 includes many download links in the 3 Planet page, but they are usually not the latest version!

Google Notebook

September 20, 2007 11:54 am

I’ve been searching for a daily software for work for a few weeks now, finally find something that I like. All I want is a simple daily, more like a advance notebook with features that helps me orgainse the notes better, something like the Tomboy notes would do the job nicely, a online one would be even better. But I can’t use that since I’ve to work on a Windows machine at work. I also don’t really want to setup another wordpress blog for it since it’s not going to be public and I don’t need all that functionality, just need something simple.

This morning I found the Google notebook, it’s quite amazing, and I’m very happy with it. The functions it supports is just what I need + a easy to use interface and it’s online which means I can access it anywhere given that I have connection to the internet! It even has a firefox plugin that makes it even better. It also supports sections and different notebooks, before I found this I used to use gmail draft to just drop down something, now it’s a lot easier. Thanks google for another amazing application/software.
