Chippy's Hiblue Lab

In my previous post I pondered over the idea that the Satio might be my next mobile phone. Don’t worry; I’m over it now!

It turns out that the Satio doesn’t run OVI maps (out of the box,) isn’t as fast as the Cortex A8 CPU might have you believe and with a waiting line of Sony Ericsson phones expected, I really don’t see it getting the long term attention it needs from it’s creators.

All that remains now is to wait for Mobile World Congress and if I don’t see anything there, the N82 will likely be my phone for the next year. It’s been good from day 1 and with Gravity, Opera Mobile and Ovi Maps to make it even better, why shouldn’t it be the perfect buddy for another 12 months?

Supplementing the N82 with a MID like the UMID BZ is working out pretty well and we’ve got the Viliv N5 and Dell Mini 5 to look forward to too!

I’m pretty much locked-in when it comes to mobile phone choices. 2 years ago I bought a Nokia N82 and the camera on that is so good that even today I’m having trouble finding an upgrade. I’m so used to taking good quality evening, home and low-light snaps with it that I rarely have any other camera with me. To me, camera, internet and mobile phone go together like bread and butter and if you’ve tasted Xenon flash before, there’s no going back. (It’s not just brightness BTW, the short period of flash helps to freeze movement and results in far sharper low-light captures of people and other moving objects.)

I took a brief look at the Sony Ericsson Satio a while back but it didn’t really register in my ‘want’ list because I didnt know about the CPU. When I found out that it’s got the same CPU in as the iPhone 3GS (AAS Review) I started to get interested again. Today I checked it out in the T-Mobile shop here in Bonn and sure enough, it’s got a lot of potential. The touchscreen is resistive but, like the Nokia N900, gives good haptic-assisted response. The slider-protected (essential) camera is 12MP and the pre-focus is quick and accurate. The only thing I found missing on the camera side (in my 10 minute test) was the ability to force the flash on (for fill-in.)

I had a great day today which is why I’m drinking more than one bottle of beer tonight. The UMPCPortal server got hit with a Slashdot article. And then an Engadget article. And then a Gizmodo article.  I woke up at 0800 to a DM from JKKMobile saying ‘Server Down’ so I rolled over, put the Archos Internet Tablet in its dock, picked up the U820 UMPC and got to work (while I sipped a nice cuppa that my wife had brought me.)

The great thing about getting hit with a Slashdot article is that it stresses your server with REAL traffic. Clearly my server wasn’t doing too well. With a Dual-Core 3Ghz CPU it was hitting CPU limits and with 100 concurrent Apache instances, out of memory and into swap space. Swap space is not something you want to be hitting on a web server.

After measuring network load, watching mod-status and top for a while I decided that I needed to reduce the number of Apache sessions to 80 which did a good job at keeping the swap partition unused. I then played around with some Wordpress cache software. None of it really worked well.

After some research and a handy tip from Hanno, I checked out some PHP cache software. This is something I’ve been thinking about for at least 12 months as my product database is written with ‘Chippy code.’ That means it’s super inefficient and generates the page dynamically from the database for every view. For pages that don’t change from month to month, that’s a poor architecture!

I settled on a very simple, a surprisingly simple, Xcache install via apt-get on my server. The install was quick and smooth and almost immediately I was seeing a drop in CPU load.

For the rest of the day I watched the traffic flow and everything has been working really well. At least I think it is.

I though it might be a good idea to share the stats I’ve seen today. It could help someone to scale or measure their own server. Feedback on this will also help me too so here goes.

Server: Dedicated, E8300 (dual core, 3.0Ghz) processor, 2GB RAM.

Server Software: Mysql, PHP5, Apache 2.

Applications: Wordpress (about 15 instances including Wordpress Mu and Buddypress), OPenX, Gallery2 and a hand-written PHP product website. Small amount of FTP and Email.

Normal load: about 20-25K pages per day. Most including some PHP/Mysql.

Current stats (Today, since Slashdot impact)

Server uptime: 9 hours 11 minutes 42 seconds
Total accesses: 1255349 – Total Traffic: 16.1 GB
37.9 requests/sec – 510.1 kB/second – 13.5 kB/request

CPU load has been between 40 and 60% average.

Apache2.conf prefork MPM config:

StartServers         2
MinSpareServers      2
MaxSpareServers      5
MaxClients          120
ServerLimit     120
MaxRequestsPerChild  4000

Each Apache process instance grows up to 30MB. Average about 15-20MB over the 120 processes.

(I’ve tuned the above to fit within the 2GB of Memory that I have. Swap kills! CPU levels are OK)

The plan is:

Upgrade memory to 4GB and increase MaxClients to 200. I’m hoping that the server can handle up to 100 requests/second of PHP from my code, from Wordpress, from OPenX (a significant part of my setup) and from various other LAMP components. I will also take a CPU upgrade though. Serving sessions and closing them off quickly is going to save memory. With an upgrade to a quad-core I’m hoping I can reach 150-200 requests per second on the single server.

I’m quite happy with the performance and the cost of the server which is about $160 per month from the very responsive and helpful Future Hosting service I’ve been using for about 2 years now but the question is, which part of my website is taking the most CPU and Memory. Is there 20% that is responsible for 80% of the load? If I knew how to find it, I’d probably be able optimise and double the capacity.

As I said, I’d be happy to have your feedback. How much traffic do you serve and what environment do you have?

I’m not a big believer in convergence. It would be nice but on the whole, it’s a stupid dream. Here are five reasons why it won’t happen. You won’t be buying totally converged smartphones.

Marketing – Does anyone think that marketing teams will let this happen? What are the chances of the marketing team saying this to the board: “We have an idea. Lets stop separate MP3 and digicam sales and just focus on selling the converged device. It’s cheaper for the consumer.”

Buying cycle – The chances are that you’ve just bought one of the devices that your converged device includes. 1) Buying something you’ve already got doesn’t feel good. 2) The chances are that the dedicated device is better.

Pricing – The price of the separate items will drop to the point where you can afford to buy a PMP, MP3, EReader. In many cases the price drops to the point where they can be given as gifts.

Physics – There are physical reasons why everything won’t converge onto a smartphone. It doesn’t take much thought to see that.

Advancing Tech – Developing a converged device requires expertise, industry partners and speed. If you don’t get that converged device to market before the next wave of technology comes along then you’re already behind the curve on launch day.  Developers of dedicated devices will always be ahead of the curve because they have a more efficient focus.

A slim opportunity

There is an opportunity for a large, dynamic, dedicated smartphone manufacturer to create a single device that 1) does not cut across products that exist in their portfolio 2)  is more usable than dedicated devices at the leading edge of technology 3) to reach a big enough scale that the prices can be brought down to ‘no-brainer’ levels.

There aren’t many companies out there that could do this but Nokia is one example. Apple, Samsung, Sony and similar multi-product companies would have problems with this strategy.

N900 and B7610

There’s some nice chit-chat going on about the camera on the N900 right now. Ari Jaaksi highlighted the rather stunning set of photos appearing on Flickr which has prompted a lot of people to go ‘wow!’

I’m holding back on recommending the N900 as a good cameraphone choice based on issues I’m seeing outside the realm of pure image quality.

A smartphone is, for most people, a snapshot camera. It’s there to take photos of events as they happen. Family, friends etc. The most important thing is that it produces the best snapshots which means being able to do more than just get a technically correct white balance or depth of field.

I tested the N82 camera against the Omnia Pro recently and here are the criteria I used to asses it. If you’re looking for a cameraphone or reviewing a cameraphone, think about the following:

There’s nothing more fun than walking from mobile phone shop to mobile phone shop trying to work out what exactly is going on in the market. For a start it’s shocking to hear the differences in opinion between shops of the same ‘brand’ and secondly, none of them have a clue what’s going on with their own websites let along what’s happening in the market. Questions about the Motorola Milestone today were met with that millisecond pause that tells you that what comes out of their mouth is going to be bullshit!

What I did discover is the following (that will only be of interest to Germans, that can read English. (note-to-self: Maybe widening your niche area might result in more visitors!)

As I went from shop to shop I tweeted my findings:

Vodafone and 02 have confirmation that the Droid / Milestone is coming. I’m a Vodafone customer who’s contract finishes in Feb so this is interesting to me but there’s something even more interesting.

O2 have an interesting ‘transparent’ system where they’ve separated the phones and contracts into different products. A phone is free and costs 5,10,15 or 20 per month over 2 years. It allows them to sell voice and data services on a month-by-month basis. You can combine multiple products in different ways which benefits someone like me who rarely makes a voice call but is connected to the data channel for most of the day. I’ve been offered a Motorola Milestone/Droid for 20 Euro per month / 24 months (480 Euros) I can then add a 0 Euro per month voice contract. (0,15 Euros per call/sms) and then (and this is the cool part) add a 300MB or 5GB HSPA (in Bonn) contract on for 10 or 25 Euro per month. (Actually they are both flat rate data but throttle down to GPRS after the limit is reached.) For 45 Euro per month I get a Droid and 5GB of lovely 7.2mbps data. Vodafone, you’ve got about 5 days to offer me something else because apparently the Milestone/Droid will be here next week.

Other updates: Amazon have one weeks exclusivity on the Nkia N900 in Germany. Nokia shop gets it one week later. (Should be under 2 weeks)

I didn’t get a chance to talk to the T-Mobile people about the HTC HD2. It’s coming soon and it looks like it will be exclusive to T-Mobile for a while as no-one else knew anything about it. The T-Mobile shop was rammed full so I left. Maybe I’ll check them out again later.

I spotted the Omnia Pro B7610 in a few shops and spoke to one person about why it took too long to reach the shelves in Germany. ‘Germany is a different place’ he said. ‘Everyone else is casual about faults but it’s different in Germany.’ I had to laugh out loud because it’s so true. The Germans are the best quality control testers in the world!

It’s funny how a walk around the shops results in a different conclusion to browsing the web. There’s an extra special element of excitement that can catch you unaware. Right now I’m seriously thinking about the Milestone for next week. If I get it I’ll start a sub-blog droid-milestone.carrypad.com My only worry is that I will end up with a QWERTZ keyboard.

Apparently Sky, is coming to the UK XBox. Today! (At some point)

Being an ex-pat with a Sky card and a father in the UK who pays way too much money to watch golf, tennis, football etc. on Sky I’m now wondering if I can get me some Sky action on the Xbox in Germany.

Apparently you don’t need a subscription to Sky but you do need an Xbox Gold subscription at 40 pounds per year.  If they can deliver BBC1-4 I’d pay 40 quid per year for that, no problem. I doubt BBC is going to be part of the package but it will be interesting to see what Sky include.

When the update comes I’ll test it out with a monthly Gold subscription.

My Xbox 360 was bought purely to front a Media Centre back-end and it’s turning out nicely. If Xbox could deliver a browser or videocast catcher though, I’d be a lot happier.

Archos 5 and the starbucks test.

Originally uploaded by umpcportal.com

There is a mobile computing test that no-one speaks of. It’s called the Starbucks test. You simply take your mobile device into Starbucks, put it on the table and take a deep breath. There are only two possible results. You either feel good or akward. Today I feel good.

Thumbs up for the Archos!

Nokia N82 in the pocket: Camera, GPS, BT, HSDPA, Voice, SMS, MP3, mobile web in the pocket.
Archos 5 IT (Android) in the hand: Quick-snack web browsing, video, navigation, ereading, emergency computing.
Gigabyte Netbook on the table: Productivity, 3G and storage.

This is getting very close to my ideal setup. 3G in the Tablet would probably be as close as it’s possible with today’s technology.

I’m currently testing out the Archos 5 Android Tablet on UMPCPortal.
http://www.umpcportal.com/2009/10/archos-5-android-internet-tablet-first-impressions-long/
It’s a bit unstable but I’m hoping that firmware upgrades will fix it.

Notice that the Omnia Pro that I bought isn’t in the picture. I’m really leaning towards keeping the N82 based on it’s digital/internet camera capabilities and the fact that the Omnia Pro doesnt really give me the web experience that I need.

I think this is the setup i’ll take to Amsterdam next week – The Maemo conference!!!

Look U driving 3 million pixels

Since I bought my full HD 1920×1080 monitor (LG W2261VP) I’ve been testing with Menlow-based UMPCs. Yesterday I managed to get the Kohjinsha SK3 driving it but it took a few driver updates to get it working at the correct reslution. Today i’m using the Fujitsu Loox U in it’s docking station and it’s driving the two displays in extended mode without any problems at all. I’ll use this as my desktop setup for today to see if I notice any issues, slowness, noise.
