On... New phone - Sony Ericsson G900

I've abandoned PalmOS for the second time

This is a bit of a placeholder, since I linked to this post from another post before I'd actually written this one. There should be a longer review along soon - no more than a few days.

Like most people, I've been through a bunch of mobile phones in the past few years, keeping at least somewhat up with technology - when I was in the UK, it was funded by subsidies from the operator once I signed a contract, but I've been buying phones retail in HK and been quite happy on a no-minimum-term contract, in particular one which gives me a decent amount of included voice minutes and unlimited GPRS. I don't actually talk on the phone that much, since most of my communication is either online or face-to-face nowadays, but having an always-on connection terminating at a smart device in my pocket is quite nice.

It's small, it's sleek, it's got a smaller but brighter screen than my Treo 680. The interface is a little slow, but the individual programs are fine. The world of UIQ3 software seems very small, even compared with the sadly shrinking PalmOS world. The built-in email software is usable, even if it behaves slightly strangely - Chatter Email for PalmOS is nicer, but that's a dead end now anyway since the author was hired by Palm. The signing thing complicates things a bit and probably contributes to the shortage of third-party software, as does the UIQ/S60 split. The built-in media player is quite nice, even if it doesn't do Ogg - or for that matter, AVI. Getting used to handwriting recognition and a phone-type keyboard rather than a qwerty keyboard is taking a bit of time. The battery life is almost certainly longer than the Treo, but I haven't really stress-tested that yet. I wish they'd just use a USB connector. Full Java support is nice, and makes the software situation a little less disastrous. I'm waiting for the first OS update for what is a pretty recently-released phone, which will apparently have some Flash support - I don't care too much for Flash, but it would be nice if it gets delivered with a newer version of the Opera Mobile browser. Alternatively, there is some work going on to put together a webkit-based browser, which should be able to handle most/all iPhone-targeted sites, which would be nice. I might do some hacking at some point to remove the Chinese support, which might make some of the input quicker. I wish it had the hard soft buttons of the G700, rather than the soft soft ones, but I think the wifi and better camera are fair exchange. Wifi on a phone is nice, but I haven't really had a chance to use it on a public network yet, rather than at home. My mobile network are offering access to their affiliated wifi network for almost nothing if you are already paying for a data plan, so I've signed up and will try it out sometime soon. It's a 3G phone, but my (current) phone network is 2G-only, so I can't comment on 3G at all. It cost me $3780, standard Hong Kong retail price, but I've got a year's interest free credit so I'm paying around $315 per month and the shop threw in: (deep breath) spare battery and charger, screen protector, SE gym-sized bag, a voucher to get some crappy stickers for the phone, a 2GB memory card, a couple of pads and fridge magnets in the shape of the phone, two cans of Coke Zero and a large metal retro-style Coke thermometer. They call it dark brown, but it's really just a slightly 'warm' black.

How's about that for a brain dump then?

On... Home networking

Homeplug and wireless and airport, oh my!

I live in a medium-sized apartment, in Hong Kong terms. We've got a reasonably large living room, two comfortable-but-not-roomy bedrooms and smallish kitchen and bathroom. During the change of flatmate, I moved from one bedroom into the other, because the new one is slightly larger and has more storage. Our broadband connection comes into the living room, where there's a file server in the corner and an 802.11n wireless router box thingy, but unfortunately, that puts the bathroom between the wireless box thingy and my bedroom. The bathroom which has thick concrete walls which do a pretty good job of blocking 2.4GHz signals, apparently. In the bedroom, there's a weak, slow and unreliable signal from the wifi box which is only really a few meters away. I'm not entirely happy about this - I've got quite used to having wireless in my bedroom for things like watching TV in bed, late-night IM and so forth, particularly with the EeePC and my new wifi-enabled phone thrown into the mix. Incidentally, a little testing shows that my GSM signal strength also drops significantly between the living room and the bathroom.

So how to solve this problem? I tried moving the wifi router box thingy around a bit, which didn't make much difference, so I decided to throw a bit of money at the problem. I went down to Wanchai and bought a couple of no-name cheap Homeplug boxes for $500 the pair (approximately £32 or US$64). There are more expensive brands and more expensive standards - there are three generations of the technology in use, analogous to 802.11b, 802.11g and 802.11n for wifi. There are strict warnings in the short documentation for the homeplug boxes saying that you must only ever plug them directly into the wall, not into power strips, but that simply wasn't going to happen - I'm a techie living in a flat with a real paucity of power sockets and it would be impossible to dedicate two of them to networking. So, I plugged the boxes in and they work - really not that much more to say that that. They are pretty slow, comparable to 802.11b, but that's okay because that's all I paid for. They have some support for on-the-wire encryption, but you need to load up some Windows management tool to do that, so I'm running them unencrypted.

Phase 1 complete - I have a working network connection in my bedroom.

Unfortunately, I'm greedy. I don't just want a working wired connection, I want a working wireless connection. The next thing I tried was to repurpose my old Dell laptop, which has been almost completely replaced by the Eee, as an access point. That was... not a great success. Without a wifi card and driver which supports running in Master mode, you're stuck with an ad-hoc network, which is a lot less reliable than Infrastructure mode, particularly in a dense urban environment where any channel is going to get interference from other wifi devices, not to mention microwaves, TV signal senders and so forth. One notable thing I did find while trying to get this to work was parprouted which does virtual bridging between networks using ARP, rather than actual bridging which doesn't work with wifi interfaces. Parprouted does seem to work, but the network itself let it down.

I finally (?) solved the problem last night. One thing which most techies have is a drawer/box/room/large warehouse filled with spare bits and pieces which were useful in the past and might be useful again in the future, and which are being stored against that possible future use. Deep in one of my storage vats was an old Apple Airport Express, possibly the first 'travel router' designed for use in places like hotels, which might provide a wired connection but not wifi, or would charge extra for it. It can also do streaming audio and run as a printer server, but I've never used those - I have used the wireless bridge before, however. After a lot of faffing around trying to get a copy of Windows XP running under kvm/qemu to see the little AE box on the physical wired network, I configured it up, plugged it all in, and I seem to have a nice reliable wireless network in the corner of my room now. It is even happily acting like a real bridge and routing between the networks, over the virtual cable supplied by the homeplug boxes, rather than doing NAT and running its own DHCP server, which is the usual mode. In the end, I've got two little boxes lying on the floor in the corner of my room, and all is well!

There's also a bright blue network cable running right across the middle of my living room, but there are always sacrifices...
