Order of the Bath

The talk on the web is about the first completely new browser for over a decade (I think). Designed from a blank sheet it promises to be popular, emphasising speed and reliability over features. Only a Windows version is available at the moment but I found that I couldn’t even download it from my Mac, it must be doing some platform detection. I will try again tonight after firing up my VM.

Adobe started to lose it some years ago when some marketing wizard decided to re-brand Acrobat Reader and call it Adobe Reader. You still find even experienced system managers confusing the names and you are never quite sure if they are talking about the real Adobe Acrobat or just the Reader freebie.

So when they announced Adobe 9 I wasn’t sure at first if they meant the full product or just the Reader (or both). Especially as we have only just had the emergency patch for Reader 8.1.2. “What patch?” do I hear you ask. Well, to digress, it was very important because it fixed a security hole that could allow those safe files called PDFs to compromise your system. Open up Reader now and click on Help > Check for Updates and it should download a thing called “Security Update 1″. Not that you would realise when it is done because for some stupid reason, the version number is not changed so it still says Version 8.1.2. While we are on the subject, if you download the Windows patch by hand it is called AcrobatReaderUpd812SU1_all.msi so it seems even Adobe are confused by the name.

Now the rest of this is hearsay as I haven’t tried it myself yet but it seems that the new Adobe 9 has bundled together the PDF Reader which we generally tolerated with Flash, the product that Adobe bought from Macromedia and which we all love to hate. It also includes Acrobat.com and Adobe Air, neither of which I have heard of. That is a 33MB download and 200MB+ install for something to just read PDF files! Also beware of the Free eBay desktop which is automatically ticked for you.

I won’t be bothering on my Mac—Preview does the job for me just fine and my Windows systems can stick with Version 8.

To those who look carefully, photographs on web pages look dull compared to how they look in photo editors. I always thought it was due to the low resolution but apparently it is all about Colour Management Profiles. These are instructions placed in the image file which tell the receiver how to render the colours and are intended to allow matching on different devices—e.g. Screens on different computers, projectors and printers. However, Firefox has always ignored them; until Firefox 3. IE ignores them as well; Safari does read them but in a different way.

In Firefox, if you go to the about:config page and set gfx.color_management.enabled to True then, after a restart, it will be activated. All the photographs will look just a little bit richer, brighter and more sparkling. The photo purists are wondering why it has not been enabled by default?

Well if you have tried it in Windows you will see—everything else will have taken on a different tinge compared to what it was before, mine went pinkish, others have reported a cream bias. The greys are no longer neutral because in the process of doing it to photographs that come with built-in profiles, they have applied a default profile to everything else on the page and it all looks wrong. The official Mozilla page says that it relies on a properly calibrated monitor. Well mine is as close as I can get it without special hardware but that is not the answer. What you also need to do is set the default profile gfx.color_management.display_profile. You would expect this to be the actual values for your monitor, but that is what Firefox is already doing. What you need to do is set it to C:\WINDOWS\system32\spool\drivers\color\sRGB Color Space Profile.icm to stop Firefox altering it and allow the Windows display driver to make the correction for the screen. Brad Carlile has a good test page—if the greys still look grey and his three test pictures all look the same then you have got it right. The Apple Mac doesn’t seem to have a problem, just set the enabled flag to True and it mostly works. Safari (at least on the Mac) does it like this by default.

Secondly, plugins, particularly Flash, do not compensate, so sites that blend from backgrounds to Flash will no longer be seamless—but my fix seems to solve that as well, unless they are trying to blend Flash with JPG which would be unusual. I haven’t got this working for the Mac yet. and, although Flash blending is ok, apparently Safari falls down for a similar reason; the CSS and GIF backgrounds don’t blend seamlessly with JPG and PNG images. This may also affect my fix but I haven’t had a chance to experiment with it yet. What I need is another comprehensive test page. Update: It is a heavy read, but this page by G. Ballard explains it all and has a lot of test pictures or this excelent article by Jeffrey Friedl.

Finally, it also takes 10–15% more processor power to render the pictures so those on older systems will see a noticeable slow down on picture heavy sites.

I first though that I would be switching it off again until they get this sorted out properly, but having found the profile hack I will leave it, I don’t care about Flash anyway.

I normally use these posts (the technical ones that is) to highlight problems with products and help people get around them. This one is different. Skype is brilliant and easy! For those that don’t know, it is an internet phone system.

The Mac Pro is one of the few Apple machines that doesn’t come with a microphone so I had to get one first. Unlike a PC it only has a Line-in socket (low sensitivity) and requires a powered microphone. It is a shame that it doesn’t provide 3v phantom power for electrets but I don’t suppose there is much call for it. Powered mics are remarkably hard to get and the easier solution is a USB microphone—it also leaves the line in socket free for other things. Some people recommend using a headset but we didn’t find it necessary.

Then install the software, create an account (most of the good names are already taken unfortunately) and you are away. The only criticism I have is that the Skype web site doesn’t give you much help around the hardware side but otherwise it is fine.

The quality is excellent and it is easy to use. I was particularly impressed by the easy and high quality conference call facility. Now if only the company system was as good as that!

We also installed on a windows laptop and that was just as straight forward. The software version is different and the windows version looks a lot more cluttered but it works just as well, even with the laptop pin-hole microphone and tinny speakers. We found that it scans your Outlook address book for know phone numbers, that may or may not be useful, but they do work quite well; apparently your first call to a “real phone” is free. Internet to Internet calls are free all the time so it is very popular for people with families dispersed around the world. It will also do video calls (I don’t think we will bother), IM chat and SMS.

Finally a recommendation. Unless you want to restrict your calls to a few designated people, fill in at least the basic information into your profile. Think of it as a phone book. I would suggest the minimum is your real name, country and city. Then at least callers can have a sporting chance of getting the right person.

Windows XP will not be available much after 30th June as that is the official end date both for the retail version and the OEM version pre-installed on machines. You may be lucky after that as it will be “while stocks last” and smaller independent system builders have until January to stop, but don’t cut it too fine if you must have one. Time to check if you have enough licences for your future needs.

Support will be available until April 2014 but I am sure that it will be a gradual wind down.

I am not going to talk in this post about how to setup this device, because it works well with the instructions provided and in most normal situations will not give you any trouble. It is a good printer and an acceptable scanner. I will, however, start off with a very strong warning—Once it is configured, leave it alone. This applies to other Canon network devices as well such as the MP800R and IP5200R.

My problem arose when I moved my wireless access point to a location that was out of range of the device. As there was a switch nearby, I decided that the best solution was to change from wireless to wired. This was not easy and to explain why and give a solution is going to get very technical and complex.

Problem description

The heart of the problem is that this multifunction device does so many things and seems to achieve them (or at least initiate them) by broadcast and recognition of the ethernet MAC address using a proprietary protocol. Here we can spot two consequences immediately: first it will only work on the same subnet (but that is generally not a problem for home) and secondly, the wireless and wired interfaces have different MAC addresses (ending in a4 and a5 respectively in my case).

The functions that the device performs are

• Printing—this is pretty much understood and well supported in both Windows XP and MacOS X. The drivers behave in a standard way and using the tools available it is fairly easy to create a new port and printer device—but don’t bother because of what follows.
• Scanning initiated from the device—This depends on a custom daemon “Canon IJ Network Scan Utility” which is waiting for messages. It is configured to watch for particular MAC addresses so doesn’t work if you switch. There is no re-configure tool available but a reinstall does add the new address to the list. Again, don’t do it yet because of what follows.
• Scanning initiated from the computer. This uses the “Canon MP Navigator 3.0.” I am not exactly sure how this works but it must need to know about the scanner address because it didn’t work anymore, and no amount of reinstalling would convince it to work.
• Mounting a memory stick. This seems to work ok because the mechanism knows about both MAC addresses anyway, but I haven’t tested it.

A Solution

While playing with this and trying to get things to work, I got into a situation where one (Windows) machine couldn’t see the device at all, even during installation and another could see it with the “Canon IJ Network Tool” but could not print or scan. I came to the conclusion that the only way forward was to start again from scratch. To clear the deck I un-installed absolutely everything. It helped that I had no other Canon software at all on the system so after using the official uninstallers I deleted the Canon folder in Program Files and, using regedit, deleted all software\canon keys in the registry. I believe that this last stage is important because that is where the addresses are stored. Now do a reboot to clear the air.

Having done this, I re-installed everything needed including configuring the printer using the USB connection, just as if it was brand new. And it works.

I haven’t done this on MacOS X because I have no idea how to uninstall things this thoroughly. Using standard tools and re-installing over the top I have got printing and remote initiated scanning working but computer initiated scanning doesn’t even start. It doesn’t help that the Canon installer keeps insisting that the machine be rebooted, an anathema to Unix based machines.

Would updated drivers have improved things? I don’t believe so but didn’t get the chance to find out as it wasn’t at all clear which versions I already had or what was available for download.

Lessons learned

• Get it right first time. Plan ahead and think before you start to install.
• This device is not designed for larger networks. e.g. it won’t work with multiple subnets and I don’t think two of these devices configured on the same computer would work too well either. Although there is a device configuration tool (”IJ Network Tool”) there is nothing to reconfigure the computer end. Even replacing the printer with a new one would be difficult.
• Don’t rely on Canon tech. support. The web site is hopeless and no one got back to me at all from a support ticket [see below].
• If possible, get one device to do one job, they are much easier to understand. I was shopping for a wired network inkjet printer. All that was available was this wireless combination printer/scanner/copier. At least it doesn’t do fax!

All this is a great shame because Canon make good printers which are economical to run and I have been very happy with them. I hope I will continue to be happy with this one.

Update: later the same day I had an email reply from Canon support. They said

In Mac, you need to select the device and move it to the rubbish bin and the same with software. Just move everything to rubbish bin, device and software. Restart before installing again.

I understand dropping applications into the Trash, but devices? Eventually I took the same drastic action as on the PC. I dropped everything that said Canon into the Trash including stuff under /Applications, /Library/Application Support, /Library/Printers and /Users/Shared. Then rebooted and installed everything from scratch again even using an (extended) USB cable. I thought initially that I was still in the same position as MP Navigator still said “Scan Failed” but on the second click it worked. Trying again, it seems it always fails on the first click. I am not convinced that I managed to delete everything as it still seems to know my scanning settings (600dpi rather than the default 300) but it seemed to be enough to do the trick.

For reference, “Canon IJ Network Scan Utility” (the daemon), “Canon IJ Network Tool” (for configuration) and “Canon IJ Printer Utility” (for printer maintenance and default settings) are all under /Library/Printers/Canon/BJPrinter/Utilities. “Canon IJ Network Scanner Selector” (to pick which scanner to use I suppose) is under /Library/Application Support/Canon/ScanGearMP/Utility. “MP Navigator 3.0″ is under /Applications/Canon Utilities. This is stuff that should be in the manual.

Despite some messages to the contrary, AVG 7.5 End of Support date is 31 Dec 2008. Changes to this policy are not anticipated but this is the link to watch. Even some notices out of the product itself say other dates.

These are WRONG.

One of the first screens you are presented with when installing Windows XP Service pack 3 (from the CD version) is one that asks “What to know before installing Service Pack 3.” A useful feature you would think, except that when you click the link a page opens in the browser headed “More information about installing Service Pack 2″ and says “2″ all the way down so I have no idea if any of it is relevant. If you click through to the “Readme” it seems to be more about SP3.

This may be a trivial point but doesn’t encourage confidence in the Quality Assurance at Microsoft.

Update: 29 May 2008—Although I have had no trouble with SP3, having now installed it on 4 desktops, 2 laptops and one virtual machine, there are strong reports about some problems. In particular owners of HP machines using AMD processors should hold off as should users of Norton Internet Security (well knock me down with a feather).

I am having a few problems using this. I am getting used to it in Mac mode but in VMware Fusion running Windows (or Ubuntu) it is a bit of a pain. There is only mapping for genuine PC layouts. This is what I get:—

This means I either have to touch type and think PC when using Windows ignoring the key caps (if I use the UK layout) or lose the £ and ¬ signs (if using the US layout). Neither is very satisfactory. In UK format I can get € (Ctrl-Alt 4) and ¦ (Ctrl-Alt §) but neither in the US layout.

Update: The best answer I can come up with at the moment is to set the guest to use the US international keyboard. This has the basic keys in the same place as the US keyboard but offers additional ones using Ctrl-Alt. This would fix the problems with @, “, \ and | but still leaves ~, ` and # wrong just as with the standard US layout. € becomes Ctrl-Alt 5 and £ is Ctrl-Alt 4. I am not sure if I prefer that or not.

The right solution would seem to be for VMware to map the keyboard through to the guest in some way.

Update: 30 May 2008. It seems the right solution is rather different as the helpful people on the VMware forum pointed out. For Windows, what you need to do is install the Boot Camp drivers. These are intended for Mac systems that dual boot into Windows and contain all the dedicated drivers for the Apple hardware. Quite a bit of it is not relevant for a VMware guest but other parts, such as the Keyboard drivers are. They are to be found on the Mac OS X install disk which is in a magic format so that, when mounted on a Windows system, it looks like a Windows software install disk. Allow it to autorun (or force it if necessary) and the package will install. Then, after a reboot, new devices will appear in the Keyboard menu which solves the problem. Now the characters that appear on the screen are the same ones as printed on the keys. I wonder how you do the same thing in Ubuntu?

Now that it is available, upgrading from AVG 7.5 to AVG 8 is a logical step but there are some decision points to be made along the way so it is best to be prepared for them.

[Note that the Free edition has some quite rigid conditions about home use only.] First you have to find it. The link I gave before is still good but it is a few clicks of Grisoft determinedly trying to get you to buy the full suite. Some of the links on the way are a bit misleading. One says that AVG Anti-Spyware is being discontinued but others that it is now included with the Anti-Virus package. The eventual download location is either their own site or C|Net downloads.com.

When you come to install it there is no need to un-install the previous version. You will need to login to an admin account. Leaving a lot out, the sequence of events is:—

• Standard or Custom install—you will need custom if you don’t need the email scanner.
• For the Custom install, Un-tick the email scanner if you don’t want it.
• Un-tick the AVG Security Toolbar if you don’t want it. Everyone seems to want you to get one of those and if you loaded them all you wouldn’t have enough window left to browse in.
• Un-tick the “Enable Daily Scanning” box if you don’t want it. I find that it is a long process and very heavy on resources (though they have put in some sort of load-limiter now). I would rather do them when I want to—and certainly not daily.
• There is a tick box for informing AVG about potentially dangerous web sites that you come across. I haven’t checked the privacy statement for this yet so I would be cautious.
• Definitely SKIP the updates at the moment as the install is not really ready for them.
• Skip the registration for the time being.
• Now you will need to reboot (it prompts you).
• When it comes back the System Tray icon will probably be red. Right click to open the AVG User Interface.
• Click Update Now and it should go ahead and do it.

That is the install complete but you need to check one other thing. One of the features of AVG 8 is the AVG Search Shield, sometimes called the Link Scanner. This intercepts results from the search engines (Google etc.) and inspects them for malicious content—try it and see the little green icons after every hit. Quite how it does that I am not sure but it seemed to take a long time and have a lot of internet traffic. I would imagine that on a dial-up connection it would be impossible. The search engines themselves do some quality checking, if this is doing it real time then it would be better but at what cost. The other thing that bothers me about this is that it could be that you are automatically visiting sites that you wouldn’t otherwise touch with a barge pole (porn etc.) and it will leave the evidence of this in your cache even if it never displays it.

If you decide that you don’t want this facility there are two ways to switch it off. You can use the AVG interface, but if you switch it off there it will forever say that AVG is not fully functional. The other way is with the browser controls. It works using a browser plugin (both IE7 and Firefix, I don’t know about Opera or Safari) and these can be disabled. Go to Tools —>Manage Add-ons—>Enable or Disable Add-ons in IE7 or Tools —>Add-ons in Firefox. This will need to be done on EACH ACCOUNT on your computer.

Now you can register at leisure, if you can figure out how. I haven’t yet! It is worth remembering that, despite all my griping, this is still a free service for which we are grateful.

Update: 20 Jun. As far as I can tell, the Firefox plugin which drives LinkScanner is not Firefox 3 compatible. It will be interesting to see how they update it.
