Dari hasil investigasi singkat kemarin, ketahuan bahwa blog ini rankingnya cukup bagus di Google untuk berbagai keyword. Dan GoogleBot juga cukup sering mampir untuk meng-update index dari situs blog ini.

Tetapi, situs umum saya justru tidak terlalu berhasil di index oleh Google. Agak aneh, karena jelas GoogleBot sudah menemukan situs tersebut kalau menilik isi file log Apache, danURL-nya juga sudah SE-friendly.
Namun, kebanyakan pengunjung situs adalah dari situs-situs lainnya – bukan dari Google.

Sayang sekali, karena ada beberapa artikel di situs itu yang bisa bermanfaat bagi banyak orang. Tapi yang membutuhkan jadi tidak bisa menemukannya, karena cuma sedikit sekali halaman situs tersebut yang di index oleh Google.

Jadi, eksperimen sedikit ah… coba kita link setiap artikel dari blog ini. Lalu setelah beberapa saat, kita lihat apakah jadi banyak yang bisa menemukannya ?

It was quite a struggle to get the setup above to work. It’s also quite scary because I don’t even know if 5MX is compatible with 6820, or if 6820 has modem functionality, etc.

But in the end, it works. You can find the instruction to get them to work here, mainly for my own future references, and also (hopefully) to benefit others in similar situation.

Note: I think it’s quite reasonable to assume that any Nokia phones newer than 6210 will be able to work with 5MX using this instruction. But, don’t bet your life on that statement.

Requirements:

• Psion 5MX & Nokia 6820
• You’re already able to access the Internet using your Nokia 6820 via GPRS
• Mobile GPRS update already applied to 5MX
• Web Browser v2.0 installed on 5MX.
• Mobile Connectivity Update installed on 5MX (may not be essential actually, but I’ve got it installed anyway)

The Steps:

1. Go to Control Panel
2. Select MODEMS > New
3. Name: Nokia 6820

19. Complete all fields in order to access your POP3 email
20. FINISHED with set-up!

Again, please note that the settings above works if you’re a subscriber of O2 mobile phone network in UK only !
You’ll need to adjust some settings above to follow the settings from your own mobile phone provider. An example of such settings can be viewed here.

Now, to actually use the email or internet:

• Activate infrared on the mobile
• Activate GPRS on the mobile
• Point at the infrared port of Psion 5MX
• Open Message
• Open Mailbox, and select an account
• A new window appears “Connect to internet” – click OK
• If you’re downloading email, ALWAYS Close mailbox before disconnecting from the Internet to avoid login problems on subsequent sessions.

Enjoy.

In anticipation to my return to Indonesia, where I expect I’ll be mobile / on the road most of the time at the day, I just bought a Psion 5MX to enable me to work anywhere.

The reasons:

1. It’s way lighter and easier to bring around than a laptop
2. While small in size, the keyboard is still convenient and speedy to use
3. It’s able to connect to Internet, and browse/email/etc.
4. There are a LOT of applications available for it
5. You can run Linux on it – and it’s Debian-based too. (minimizing the need to compile software, which means longer CF card life)
6. It runs Linux without destroying what’s already on it – a small program will cause it to boot from the CF card, which has Linux installed in it
7. It’s a bargain (most especially when you compare it to laptop price ) at about 100 poundsterling
8. It’s a very convenient voice recorder – it has dedicated buttons for this feature, so you can record straight away without having to open it first. It’s very important for me because I’m very forgetful I really hate it when I forgot brilliant ideas because I wasn’t able to record it when it occurs. I almost bought separate device for this – lucky for me, 5MX can do this too.
9. It uses 2 x AA batteries, not some weird proprietary battery. So when it runs out of power, I just need to buy AA batteries – which is available pretty much everywhere.
10. The Psion community is amazing – you can find the solution for your problem on Google quite easily. Or when you need to ask questions, the community is very helpful

This afternoon, I’ve managed to get it to access the Internet via Nokia 6820 :
Internet — GPRS — Nokia 6820 — infrared — Psion 5MX

It was quite a struggle to get it connected for the first time, but now it’s rock solid.
Sweet.

Someone probably will argue that it’ll be more convenient to connect via Bluetooth (and use different PDA), why do you use such antiquated thing, and so on.
However, I’ve yet to find any other PDA with the features listed above, so it’s Psion 5MX for me at the moment then. Do feel free to let me know if you find anything else that can beat that feature list.

5 years in writing (see bottom of page), ARP has now released the latest version of their Virtual Memory Optimization Guide (version 4.1)

Since hard disk is WAY slower than RAM, increasing virtual memory / swap performance will always give you instant increase in overall system performance.

Of particular interest would be movingswap file to outer tracks (max 200% performance gain), create multiple swap file on different hard disks (just make sure to read this as well), and stopping Windows from paging itself to disk.

A recommended read.

People are still busy with spyware; sure it is a problem. But reading their recommendations on combating the problem does make you wonder a bit.

If you have a good firewall, use Firefox instead of Internet Exploder, doesn’t install dubious software (read: kazaa, morpheus) – then you can be quite sure that your PC will be free from Spyware.

Alternatively, use Linux
