I’ve googled and I’ve browsed various forums and haven’t found the answer, so I’ll put my plea here. Is there an easy way to share one iPod between 2 computers? Normally, I just sync my 20GB iPod at home and leave it at that. However, the full-sized iPod started to feel a bit bulky to be carrying around all the time – so I’ve just bought myself a 1GB iPod Shuffle for the daily commute. Now I’d like to be able to sync it at home and at work.

When you plug an iPod into a machine with a different iTunes library to the one you have it set it up for, the software asks you if you want to associate the iPod with the new library. Doing so wipes out all the tracks on the iPod and if you wanted to sync with your original library, you have to repeat the process. I read somewhere that if you click “No” when it asks you to associate with the library, the iPod should work in “manual” mode – it shows in iTunes but you have to drag tracks onto it to load them in. This doesn’t seem to work for me, as the Shuffle never shows in iTunes.

My home library is on my iBook and my work machine is running XP, if that makes a difference.

I would prefer to stick to using iTunes, if possible, but if there’s a good bit of cross-platform software that will do what I want, I’d be willing to give it a try. So… anyone got any ideas?

Since rolling out Windows XP SP2 around the office network, I’ve come across curious differences in the way Internet Explorer handles file form inputs (input type="file"...), before and after SP2 is applied. At least I think I have…

Some Context.

Pre-SP2, it seemed possible to just type in a value to the input (rather than use the Browse button). For example, a user could type in ”/home/chris/my_file.txt”. In the context of our intranet, “not applicable” was a valid value that the user could enter.

The Issue.

Once SP2 was applied, this no longer worked. In our Intranet system, typing in a value produced an error in our server-side validation script – the script thought that the input had been left blank. Curiously, the page returned by the server had a javascript error warning (“Object Not Found”), despite there being no client-side scripting done on this particular page.

If the input was given a value by clicking on the browse button and selecting a file, everything would work fine.

This issue has caused us a few problems, as a few of our intranet apps suddenly “broke” with no immediate or obvious explanation.

Over to You

Has anyone else come across this little quirk? Could someone else confirm or debunk this?

I must admit to not testing this in any great depth, but I have come across this problem on a number of different pages (not all on our intranet), using a couple of different machines. I did a quick google search and nothing related came up.

Or is it all me fault? Actually, don’t answer that…

Some pure geekery ahead – and possibly a lot of misinformed rambling. You have been warned! This is as much for me as it is for you guys… I had a load of this stuff going around in my head so much today that it was getting distracting.

One thing anyone who really knows me will tell you, is I’m very interested in the whole media centre PC thing (also known as HTPCs). I really like the idea of storing/accessing all my media content (music, TV, film and photo) through one networked device which connects to my TV/speaker system and has a nice, friendly, interface. Heck, to be honest, I’ve been eying up having a decent home cinema system in any shape or form for some time – the HTPC route is just the most appealing of late. At the moment, I have a fairly cheap DVD player, my Gamecube, and a Sky digi-box – not exactly the most cutting edge setup!

The HTPC has been begging to be built for some time. In fact, I’ve got all the bits except the case. I did make one previous, aborted attempt, using a VIA Mini-ITX board and Linux – but hardware compatibility issues killed that one off. This time, I have a 3.2GHz P4 monster just waiting to find a new body. I’ve got my eyes on a DiGN HV5 case, but it’s expensive enough to make my wallet whimper in fear.

The biggest problem, however, is when the time comes to connect everything together.

Here in the UK (I don’t know about anywhere else), most AV connections are done through SCART sockets and leads. It provides good quality audio and video connections using just one cable. The Sky Digibox produces best results when connected via SCART. My lovely widescreen TV has only two SCART connectors and an RF connector (it also has an S-video and RCA connections, but these are on the side of the TV – not practical when you have a toddler). The HTPC doesn’t do SCART. Doh.

What the HTPC does do, is S-Video and SP-DIF audio in and out. It also does good old RF in. This is where a new box of tricks is introduced: the A/V Receiver. A good A/V Receiver will take all your audio and video inputs and let you switch between them. It will output your sound to your speaker systems (after running the sound through an internal Dolby/DTS decoder and amp/preamp) and will give you a variety of ways to output the video signal. So in my case, the inputs would be my HTPCs S-Video and SP-DIF, and my Gamecube. The output goes to by TV by way of a component to SCART converter.

You may have noticed something missing from the above – the Sky digi-box. This is where I’m not sure where to go. The digibox really, really, really wants to be plugged into a SCART socket. Unfortunately, I want to run it through my HTPC so I can record TV and do all that other cool DVR stuff. The simple thing to do would be to run it into the RF socket of the TV tuner card, but I’m not too sure how much the picture/sound quality would suffer… Does anyone know by any chance?

While I’m canvassing opinion, I will add that if anyone has any suggestions for my setup, please give them. I’ll point out that I’m on an extremely tight budget, but I’ll hear any and all advice!

Pixel Meadow has been online since September 2004. In that time, I’ve written (fairly) regularly and hopefully haven’t been too boring!

Prior to opening Pixel Meadow, I had another site. This site had an almost schizophrenic nature. One month it was an out and out blog. The next month it was a developer site. The next, it was both, then a portfolio/CV site… and so on, etc. With no clear focus, it’s a surprise it lasted as long as it did. I grew bored with it often, neglecting it for months on end. Pixel Meadow was me moving forward, getting focused.

However, ChrisMcLeod.Net was my first real website. Before that, I’d just mucked around with homepage builders on various free hosts such as Lycos Tripod. So there was an attachment there that meant that I couldn’t just shut it down and forget it.

Over the last few days, I’ve been working on the archives of my old site; cleaning and recategorising them. Today, I have added them to the archives of Pixel Meadow.

These additions represent everything that was left of ChrisMcLeod.Net. Over the course of its life many changes occured and data was lost – so these additions don’t represent everything that I’ve written there over the years.

It’s been an interesting process looking over old entries. I can see a definite improvement in my writing. I’m a bit more focussed and less “ranty” then I used to be. No matter the quality of the writing, I’d like to think that adding these old entries will add depth to Pixel Meadow as a reflection of self.

I’ve been fascinated by the Transformers – the “Robots in Disguise” – since I was a young’un. There’s just something about giant robots that transform into everyday vehicles and objects that is plain cool!

As is the way, most of my original toy collection was thrown out long ago. However, during the later stages of my stint at University, I happened across the (then) latest toy line. That was it – they’d pulled me back in. A couple of years later and I had a fairly substantial collection again, covering toys, DVDs and comics. For a while, I even ran a (now defunct) community site for fellow collectors.

I still have my collection, but it’s packed away in the loft, for the most part as there’s just no room for it in our home. It’s a bit of a shame, really, but it needs to be done. I think that I’ll probably sell it on ebay one day. After all, I think it’s maybe better in the hands of someone that can appreciate it properly.

I’ve had my iBook for about 48 hours now, and I’m beginning to find my way. OS X (or is it OSX?) is a completely new experience to me, but I think I’m taking to it rather well. I’m still getting used to the difference between shutting an application and quitting an application, but that’ll come in time! For what it’s worth, I wanted to jot down my initial experiences and reactions with the switch. I won’t go into too much detail just yet – I’ll save that for later articles.

  • File browsing is more intuitive, especially after I switched to column view in Finder.
  • A lot more emphasis is placed on using keyboard commands than in Windows…
  • …Which is just as well, as the trackpad is a bit pants.
  • Software installation is a breeze. It’s so simple and logical. Drop the application into the applications folder and away you go!
  • I’m still not sold on the Dock, but I haven’t done any tweaking yet (other than the size of it)
  • Everything just looks better. From the icons to the text to the GUI widgets… it’s just better!

So far, I haven’t done anything to set up the machine for local development/testing. I plan to do this later this week, after I’ve done a bit more reading – I want to set up SVN and Ruby/Rails, both of which I’ve never set up before (or even used before, in the case of Ruby/Rails!). Another thing that I haven’t done yet, is transferred any old files onto the iBook. That’s tonight’s job.

Ok, so it’s official, I’m switching to Mac. The iBook is all but fully ordered – I’m just waiting on my next pay cheque to come in. It’s sitting there smugly in my saved basket on the Apple Store UK. I can virtually hear it saying “I knew you couldn’t resist!”

Barring any last-minute changes of heart on just how much I’m going to spend, here’s what I’ve gone for:

  • 12-inch iBook G4 with 1.2GHz processor
  • 14-inch iBook G4 with 1.33GHz processor
  • 60GB HDD
  • Bluetooth module
  • Additional 512MB RAM from Crucial

I’m lead to believe that installing the additional RAM will be a piece of cake. Far easier than spending the extra £140 for the same amount of RAM from Apple…

I’m counting the days already.

So… anybody want to buy a 18 month old Centrino laptop?

Update 15/01/05 Ok, so I finally managed to find somewhere local that had iBooks in stock for me to give one a test drive. The 12” screen was a little too small for me, so I’ve upped my spec to the 14” model. To offset some of that extra cost, I’ve dropped the bluetooth module. So basically, I can just buy one off the shelf at the store and do the RAM upgrade later. As a bonus, the store guarantees everything for 2 years – so no paying for extended AppleCare!

I witnessed something quite bizarre on the way home from work today. I’d popped into our nearest PC World store on the way, to pick up a USB hub for my parents (2x USB Ports + 8 USB devices = cable nightmare). While I was browsing around, edging closer to the Mac section as I usually do, I overheard another customer talking to a member of staff about antivirus/security software.

Unfortunately, it’s a habit of mine that when a store sales person is talking about anything computer related I listen in to see how clued up – or not – they are. With PC World, normally the staff aren’t particularly good. This staff member seemed reasonably knowledgable about spyware/virii, how they get on your machine and cause havoc and how to avoid them. Slightly better than average I’d say. He was recommending an overpriced, not-so-good bit of software though…

Anyway, conversation finishes and customer leaves contented. It was only then that I realised who they had been speaking to – the store security guard! I was amazed, simply because he seemed more clued in about computers than most of the other staff I’ve had dealings with in PC World (or most big chain-stores for that matter). I hope they pay him extra for being a decent salesperson as well as keeping the store secure!

When I implemented dated URLs for the blog, I mentioned that I had a particular idea that I wanted to implement. This idea is simple enough – an easy, convenient way for a reader to find entries in the archives. The basics of the idea are explained, in Michael’s discussion on his recent redesign. He calls it a “Digging archive system”, for lack of a better term. Think of it as a “lite” version of Apple’s Finder, but for you weblog archives.

Since Michael explained what he was looking, I’ve been thinking about the problem a lot. It’s an incredibly cool/good idea. The trick is implementing it. The page shouldn’t reload as you dig through the archives, which excludes a purely server-side solution. That leaves XMLHttpRequest (ala Livesearch) or preloading all the data on the page when it loads.

As cool as XMLHttpRequest is, I can’t think of an efficient, graceful method of achieving the desired look ‘n’ feel (if anyone wants to show me a way, feel free!). Instead, I’ve been leaning towards a mixture of CSS and DOM to provide a solution

By using nested lists, we can build up a semantic structure of the archives. In my example it is structured by date, but I can also imagine things working for the standard section/category structure of a standard Textpattern site. Consider this (very) basic structure:

[image lost]

Obviously this would be far larger depending on the size of the archives. The classes are there to allow you to style the lists in case javascript is turned off. If javascript is available, we add a second class to the <ul> elements, otherwise they are left alone. Graceful degredation is good. In the same vein, the idea is to not have to use onclick="..." attributes in our XHTML, but to use DOM to add the event listeners. Gotta keep the code clean!

I can imagine the system working like this:

  • The latest year/month/posts are displayed by default
  • Only years/months that have posts are listed.
  • When a reader clicks on a month, the relevant posts are displayed and previously displayed posts are hidden
  • When a reader clicks on a year, all the previously displayed months are hidden and the relevant months are displayed
  • Clicking on a post title takes the reader to the entry.

Toggling the visibility of a list is handled by setting its display property to either “none” or “block”. All other layout is controlled by the stylesheet. So we could end up with something that looks like the following (top is what it looks like with javascript enabled, bottom is how it would display otherwise, if CSS is still enabled) –

[image lost]

That’s the theory, anyway. The problem is that I haven’t got that much in the way of DOM/Javascript “m4d sk1llz”. Is there anyone out there that might be able to point me in the right direction or otherwise help out?

What’s that? A bloody good game based on Warhammer 40,000? Are you sure? Well, wonders never cease…

It’s true. I’ve just finished playing the beta version of Warhammer 40,000 – Dawn of War… and by jove it’s good. Bit tricky to play on a laptop with just a touchpad, but damn good none the less!

It’s about time that the Warhammer 40,000 franchise had a decent computer game. It’s one of the richest fantasy worlds since Tolkien came up with Middle Earth. The back history is exceptionally compelling; the story of a massive yet fragile Imperium of Man that stretches far across the Galaxy – and of the Alien races that it rages constant war with. As the line goes: “in the grim darkness of the far future this is only war”.

On the surface, the game itself seems a pretty standard RTS. Be thankful they didn’t go for a turn-based game like the table-top game. That would’ve been a disaster. By going realtime, the game is far more exciting and faster to play. There are a few neat tricks to it though.

Graphically the game is gorgeous. Everything is in complete 3D. You can zoom right in on an individual trooper if you want and marvel at how detailed he is. Explosions and weapon effects have a good feel to them – you can really appreciate the rain of fire tearing through an enemy squad when your Space Marine Heavy Weapon Squad let loose a volly.

A fairly novel difference to most RTS games is the resourcing aspect. To gain more resources for building more troops or getting upgrades you must capture and hold onto sections of the game map. These are either “Strategic” points (run-of-the-mill areas that it’s good to control) or “Critical” points. Critical points tend to be the basis for some mission objectives.

There are four races available in the full game: Space Marines, Orks, Eldar and Chaos. Only the Marines are available to play as in the demo. Space Marines are the finest troops of the Imperium; genetically modified, heavily armed and armoured. They have the most balanced and versatile troops and heaps of killer vehicles. The Space Marine Dreadnought is absolutely lethal against most troops and vehicles. Space Marines also tend to not run away much – another vital aspect in the game.
Orks fight in huge mobs and use low-tech weapons salvaged from scrap left on battlefields. Ork tactics tend to be to grind the opponent down with wave after wave of troops, backed up by their “Big Gunz”.
Eldar are Elves in space. Highly advanced technology but not many of them around to use it. The Eldar have tend to use fast troops that hit hard then get away before you can retaliate properly. They can also upgrade squads to specific tasks such as close combat or ranged fighting.
Chaos are the real baddies of the game. The legions of Chaos are Imperial troops seduced by the Gods of Chaos. As such, they fight much like the Space Marines but with one big difference – Daemons!

I’ll stop rabbiting on now. I’ve already gone into far more detail than I planned to! This has turned into a mini-review… Suffice to say that I’ll be going out later today to buy the full version of the game.

Sometimes you just can’t ignore the temptation to tweak and tinker with your work, especially when it’s a personal site…

One thing about web development that I have a love/hate relationship with, is the desire to constantly tweak and fiddle with what you’ve done.

Even something that you’re immensly proud of and happy with; you’ll get the urge to go back and change a little bit here, improve a bit there.

This is especially true of blogs/personal sites. Because it’s yours, you can do what you want with it.

Take here for example. A few days ago I had a design I was reasonably happy with. Then for some reason I decided I wanted to try my hand at porting Kubrick to TXP. Boom-baddah-bing and here we go. Most of the site now uses the Kubrick style (albeit with a number of changes) and I’ll be moving the rest over as and when.

Once I get this distraction out’ve my system, I’ll get back to the XML-RPC script. Promise.

Now that I’ve got the awkwardness of the first post out’ve the way, we can move on…

Ever since moving into the new house (about 3 months ago), I’ve been rethinking my computing needs. I’ve got a pretty big under-stairs cupboard that’s being eyed-up for conversion into an office. While it may be larger-than-average, cupboard wise, it’s not quite big enough to accommodate all of my hardware, so something has to go.

Deciding what was to be turfed out meant evaluating exactly what I use a computer for when at home. Do I need a big, gaming orientated desktop, when I have two games consoles that aren’t exactly getting worn out by over use? Do I need a high-spec Centrino laptop when I’m never more than 2 meters from a power socket? What about that Epia-based Media Center that’s gathering dust in the removal box?

It’s all a bit OTT, really.

Once you start looking at the hardware, attention inevitably turns to the software/OS side of things. Do I like WinXP? No, definitely not. Does it have good software? Yes. Do I like Linux? It’s better, but a pain to setup/manage – particularly on my laptop. Does it have good software? I guess, but not so far as web development stuff goes, IMHO. What about Mac?

Ah. Mac. I’ve never used a Mac before. I know nothing about Macs. Other than they look pretty. Really pretty. Actually, I do know something – they have a fair bit of good web development software. If all else fails, Macromedia Studio MX is available on Mac.

A Mac is sleek and sexy. A Mac is powerful. A Mac is… how much…? A Mac is expensive. Or maybe it’s just me. Getting onto the bottom rung of Apple systems will cost £600. That’s the very bottom, barebones eMac. Prices then go astronomical once you start adding features like AirPort, Bluetooth, SuperDrive or even just bigger RAM or harddisk. But that PowerBook looks so damn sexy…

It’s all a muddle and no mistake. What would you do in my position? Stick it out with the laptop + whatever OS you think is best? Get a new PC/laptop? Get a Mac? I need help choosing people – influence my weak mind!

[Editors Note] This was the first post on my Pixel Meadow blog, but obviously not my first ever blog entry.

Writing your first line is hard. From English classes to blogs, everyone has struggled to write the opening sentence. This short entry recognises that fact and pays tribute; looking back at how others have started before me.

Writing the first line is the hardest part of the writing process. Remember back in school? You could sit for hours trying to come up with the opening sentence for the essay your English teacher wanted in the following morning. The rest of the essay was always easy by comparison.

It was the same with that love letter you wrote to your sweetheart; the first line in your million-dollar film script; the first post in your blog and every post after.

I was curious to what other writers had put in the first posts on their blogs.Dan@SimpleBits alludes to an older version of his blog and how this one will be different. So does David@MezzoblueJon Hicks welcomes you to his lab.Dunstan wrote about Paris. “First Post!” is all Michael had to say. Othershumbly welcome you to their blog and explain why they’ve started writing. I nearly joined them. Some write to share information, others write to get better at writing.

This entry is a tribute. At least, I’d like to think so. A tribute to the first line; the opening sentence; the first post. I’d like you to think back to where you started from. That mountain of effort that started your blog. Share what it was like.

Welcome to my first post.

Malarkey has just posted a fine summery of the pitfall of the various “badges” that currently litter a lot of “standards compliant” websites. You know the ones – they point to the various validators.

A few pitfalls are identified –

  1. They’re pointless if your site doesn’t quite validate for whatever reason (which is subjective with the accessibility validators anyway)
  2. They offer the Average Joe absolutely no explanation as to what they’re about. Instead, they just plonk them in a highly confusing, jargon-filled site.

He then offers a far better solution – link to an internal page that explains what the buttons mean. That way, you can still claim your site validates while actually informing people what it means.

It’s a solution I agree with – expect to see it in use here shortly.

Ever since I joined Technorati and “claimed ownership” of this blog (and Gentooist), my Technorati Profile has always read “No Verified Blogs”. What exactly do I have to do to change this? I thought the instructions were something along the line of:

  1. Signup to Technorati
  2. Add a Blog
  3. Embed Technorati profile link in pages
  4. Setup MovableType to ping Technorati when posting an entry
  5. Write

Am I missing a magical step? I’ve done all that, written several entries since joining and yet there’s been no change. The mind boggles!

Hopefully a more enlightened user will hear my call and be able to shed some light..?

Just came by this massive list of great web standards articles by way ofSimplebits (where you can also find this list).

I think, out’ve the 450+ links, I’ve read around about 30 or 40 of them…
Time to get reading!

For posterity, I’ve duplicated the full list below.

Mahoosive List O’ Links

I just discovered this wonderful series from Asterisk*.

Being as I have worked with bands before (while I was still a young wasterstudent), and still have a bit of interest in the local music scene, I’ve struggled along trying to create a website that promotes a band image, is useful to the users and is basically… something to be proud of. I must admit, looking back, I failed everytime.

Looking at someone else’s design methodology is always refreshing and inspiring, especially if you can identify with the subject.

Hmmm. I (almost) fancy doing just one more band website…

There is one thing on the internet that is – without a doubt – causing more buzz than anything else at the moment. No, not the new Harry Potter film (worth going to see, by the way). I’m talking about Gmail.

For weeks since it was announced, the blogosphere has been buzzing about it. Some have snorted in derision, some have placed it high upon a pedestal. Gmail isn’t even fully open to the public yet – it requires an “invite”.

These invites are highly desirable, so it would seem. All over the place, I’ve seen various contests to win an invite. Some ask you to come up with something funnyOthers just want a link (so can I have my invite now? 😉  ). The slightest mention of having a spare invite prompts a deluge of people you don’t even know asking for it. Googling for “Gmail Invites” returns page after page of people pimping this strang type of gold dust.

I guess it’s this process of invitation only accounts that are making everyone want Gmail so badly. To be in an “exclusive club” is quite a draw for some.

If it’s not that though, what is the draw? Is Gmail any good? I’ve put out the feelers (ooh-er) for an invite, so I’m hoping to be able to find out for myself, but maybe someone could enlighten me?

Isn’t just another web-based email service?

Last Updated: 27/May/2004

The Samsung X10 was, for a long time, the thinnest notebook available. It’s also silver and all shiny. Obviously, I just had to have one! Specifically, the XTC1400 which boasts a Pentium-M 1.4GHz, 512Mb RAM, 40GB disk, CD-RW and wireless networking (it’s a Centrino notebook).

By default, it comes with WinXP Professional. Obviously, that just will not do! Unfortunately, it’s not the easiest laptop in the world to install Linux on. I’ve done a number of installs with several distros and have had wildly differing results – even between reinstalls of the same distro! Eventually though, Gentoo won the day…

Not that it was an easy process, mind you. Indeed, as I type this, a few features are still not working (read: ACPI). But by and large, the laptop is fully usable for day-to-day tasks. Even my Girlfriend can use it, so it must be ok!

Here’s a quick run-down:

  • Kernel – currently 2.6.6 love4. Seems very stable and relatively nippy. Edit 27/May/2004 – Now using 2.6.1 + a handful of patches.
  • Display – The biggest stumbling block for the X10 at one point. Using XOrg X11 + the latest Nvidia Kernel & GLX (5336) from Portage works a treat.
  • SoundALSA’s a bit temperamental at the moment. I had it fully working at one point, but forgot the fix when I did a reinstall. Normal users get a “Cannot find /dev/mixer” error. I know it’s fixable though, but I want to get other pieces working first.
  • Networking – The wired LAN card works a treat straight off the bat. The WiFi card took a bit of work though. Read this post on Centrino Wireless + Gentoo to get it working. I’ve had no need to use the modem, so I don’t have a clue if that works or not… From what I’ve read, it might only work with a 2.4 kernel.
  • ACPIThe major stumbling block at the moment. Some things are working, others aren’t – at the moment, only the AC adapter and battery aren’t being picked up. The problem lies with the common (missing?) ECDT error. I’ve tried adding the several potential patches to the kernel, but none have ever installed properly. Edit 27/May/2004 – fixed by reverting to 2.6.1 kernel + patches. Guide Coming Soon.
  • Speedstep – I’m not going to try the CPU frequency scaling until I’ve gotten ACPI properly working. Just in case.
  • Touchpad – Using the Synaptics touchpad driver, everything works apart from the scrollwheel/middle button. No matter of tinkering could get this to work. The driver does provide features that make up for this, but in the end, I installed a MS Bluetooth mouse instead… (guide coming soon)
  • Keyboard – Not tried to get the extra keys going yet. Last time I installed I couldn’t get them working, but I didn’t exactly try hard.

Currently I’m running Gnome 2.6 and find it very responsive. Apps load up quite fast, although I’ve not been doing anything particularly strenious with the machine since I installed Gentoo.

This page will be updated as I get more things working (and write the guides for the fixes)

Centrino is the big thing in laptops at the moment. Longer battery times despite more powerful processors and inbuilt 802.11b wireless. Unfortunately, Intel have yet to provide Linux support for the wireless component of Centrino and are a little cagey as to when it will be available.

Thankfully, the open-source community is a crafty community. NdisWrapper provides a method of loading Windows drivers to enable the wireless card.

At the time of writing, there are ebuilds in portage for NdisWrapper (latest version is 0.6-rc1). Unfortunately, they seem to be quite buggy and I’ve yet to get them to work. Instead, what I found to work best was to get the latest version from the NdisWrapper site and compile it from that source. At this time, the latest version is 0.7. Then follow the steps below to release yourself from your cat-5 tether!

Note 1: as a prerequisite, you need to emerge wireless-tools.

The Driver

  1. Download the latest source tarball to your system from the Ndiswrapper Sourceforge Project and unpack the archive.
  2. For the Intel PRO/Wireless 2100 (standard Centrino wireless card), download this driver. Otherwise, consult the NdisWrapper homepage.
  3. Open up a terminal and su to root then cd to the directory you extracted the source to.
  4. make install
  5. Unpack the Windows driver and check for a .inf file. In the above package, it should be “w70n51.ini”.
  6. ndiswrapper -i /path/to/win/driver.inf
  7. Once that’s done, type ndiswrapper -l. The name of the inf file should be listed. If not, you may have mistyped the path, so try again.
  8. modprobe ndiswrapper to load the driver. Providing there are no errors, typing dmesg should return “wlan0: ndiswrapper ethernet device…”

Configuring Your Card

The next bit will either be straight-forward or trial and error. It just depends on your setup. I had a bit of bother getting the right combination of authentication settings before I got my card to work.

iwconfig should list your card and its current settings, which will be all empty. To change this, you need to do the following:

  1. iwconfig wlan0 mode Managed if you use and access point. Otherwise, set mode to “adhoc”.
  2. iwconfig wlan0 key restricted <wifi key> will set your authentication key (hex format). Pass the -s option after key to type the key in ascii format. Depending on your setup, you may have to subsitute “restricted” for “open”.
  3. iwconfig wlan0 essid your_essid sets your network ID.
  4. ifconfig wlan0 up should now bring your wifi card online. If not, fiddle around with the settings above. Also take a look at the other options you can set through iwconfig.
  5. DHCP users should type in dhcpcd wlan0 to assign an I.P. to your card.
  6. Alternatively, to assign a fixed I.P. you need to copy /etc/init.d/net.eth0 to /etc/init.d/net.wlan0 and edit accordingly. Then type in /etc/init.d/net.wlan0 start.

If you were to ping Google or similar, you should see your connection working.

Final Steps

The tricky bit is now out of the way. All that should be left to do, is to get the card to come back up at boot time:

  1. Add ndiswrapper to /etc/modules.autoload.d/kernel-<kernel version>
  2. If using DHCP, add the five steps in “Configuring Your Card” (above) to /etc/init.d/local.start.
  3. Otherwise, you’ll probably want to add the net.wlan0 file to startup with rc-update add net.wlan0 default.

That should be it! I’ve been happily connecting with the card in my Samsung x10 since I reinstalled Gentoo about a month ago.
One point – DHCP users might want to try the net.wlan0 method of configuring/bringing the card up/down instead of using local.start. It seems to be the “correct” way to do it and a lot “cleaner”.However, I had no success getting this method to work with Ndiswrapper 0.7 (0.4 worked, IIRC). That’s not to say it won’t work for you, it just didn’t work for me… Give it a try by all means, then let me know how it went by leaving a comment.

This post was originally inspired by this thread on the Gentoo Support Forums.

It seems that SPAM is forever on the increase. Daily, our inboxes are flooded with offers of riches, pills, or other such junk. Dealing with SPAM can take a long time – time that would be better used on something more productive (like Unreal Tournament 2004…)

There are tools for helping to automate the task. Nearly all mail clients allow you to setup filters to direct messages that match certain patterns to certain mailboxes. With the all the different tricks used by spammers, this can lead to a lot of filters having to be setup! Some clients (such as Mozilla Thunderbird) have built-in anti-spam filtering. Depending on the level of mail that you receive, these might be perfectly adequate for your needs.

Sometimes though, you just need a little bit more power…

SpamAssassin is a powerful program for filtering SPAM from your mailbox. I’ve seen it used a lot on the server-side – filtering messages as they come into a mail server. It can also be used client-side, which is the method we’re going to setup today.

Evolution is the mail client/calendar/task list program from Ximian (now part of Novell). It’s a pretty powerful app, on a par with Outlook in most respects, but with none of the flub. It offers a lot of options for filtering your mail, including one very useful option in particular: “pipe message to shell command”.

Can you guess what we’re gonna do? That’s right. Use Evolution’s filters to pass incoming mail to SpamAssassin, then decide what to do with the message based on its spam score. Ready? Then lets begin.

emerge evolution

Let it churn away…

emerge SpamAssassin

More churning…

When all the compiling is done, add the spamassassin daemon (spamd) to the default run level so it starts at bootup:
rc-update add spamd default

If you haven’t already done so, set up Evolution with your e-mail account(s). Next comes the laborious part – setting up the quarantine area, the training area and the filter.

Create a new folder in Evolution, called Quarantine. This will be where messages marked as spam will be put. Now create a subfolder under Quarantine called SPAM Training. This is where we will manually place SPAM mail that SpamAssassin misses and later use it to train SpamAssassin to catch it next time.

With the folders setup, lets create our filter. Filter options can be accessed under Tools > Filters. Create a new filter called “SPAM” (or similar). The settings for this filter should be:

pipe message to shell command spamc -c returns greater than 0
move to folder "Quarantine" in "Local Folders"

That should be it. Instantly, you’ll find less spam in your inbox as it gets filtered into your quarantine folder instead. You could set it to delete spam instead of quarantining it, but there’s always the chance of false positives, so I like to double-check the quarantine area every couple of days in case there’s something there that I might want to keep.

Inevitably, some spam will get through. To deal with this, we need to train SpamAssassin into a lean, mean, spam-eating machine. Remember the “Spam Training” folder we set up? Now’s when it comes in useful. When SpamAssassin misses a message, manually move it into the training folder. Then, type the following command, changing @@ with the path to your home directory: sa-learn --spam --mbox "<home dir>/evolution/local/Inbox/subfolders/Quarantine/subfolders/SPAM Training". This command tells SpamAssassin to look in the folder and that everything in it should be classed as spam from now on. After a few days/weeks of training, the amount of spam in your inbox should drop to next to zero!

If – like me – you do a lot of “tinkering” with your Gentoo installation, you’ll invariably end up typing a lot of commands over and over again.

Aliases save you from having to remember/repeatedly type in these commands. Aliases, in case you are new to them, are command line shortcuts. As such, they can save you a fair bit of time when working in the terminal.

To set up an alias, you use the alias command:
alias aliasname='command'

There are a couple of Gentoo specific aliases that I have set up:

  • unstablemerge—a shortcut to ACCEPT_KEYWORDS="~x86" emerge
  • retrymerge—saves typing in emerge --resume
  • rc-add—instead of rc-update add
  • rc-del—instead of rc-update delete

From The Register

Computerised lamp posts look like being the basis of the biggest data network ever, as the world’s traffic monitors set about controlling cars with wireless. And the result could be an absolute windfall for a startup company which, it seems, owns all the relevant patents.

The whole article reads like some sci-fi nut’s dream… but it could become very, very real. If an entire city or town or even a simple road was a big, internet connected wireless hotspot, you could pretty much access information anywhere. How cool/scary is that?

Microsoft’s Internet Explorer is the dominant web browser out there. There’s no denying it. However, it would appear that its grip on the top spot is slowly – but surely – loosening.

Reviewing the site stats over the last two months (well, 43 days to be exact), there has been a fairly substantial increase in the number of unique visitors using Mozilla. In the first few weeks of the stats, Mozilla (and Firebird – the stats don’t differentiate) accounted for around about 12% of all site visitors. IE6 had approximately 78%, with the rest mostly going to IE5.x/Win, IE5.x/Mac and various minor versions of Opera 7.x.

However, looking at the stats tonight shows the Mozilla browsers at 18.67% – a 6% increase! IE6 is down to 71.89%. A surprise new entry is Netcaptor, which grabbed 3rd place with 2.36% of visitors using it. The rest of the top ten is still IE5.x and Opera 7.x fighting it out.

Just goes to show that IE isn’t the only browser you should consider, when you design web sites. There’s a significant number of users out there that have started using (the far better) alternatives. After all, if my stats are any indication of the web at large, that would mean that an IE only site cuts out a potential 30% of visitors. How can anyone justify a number like that..?
