Time to stand up and be counted

Okay. I appreciate that some people don't care to read about politics and/or religion, especially if they're expecting some geeky tech-rant. So that's why I've split off my posts about belief, or the lack thereof. You can still find my opinions on technology and other stuff over at witteringon.blogspot.com, but anything to do with crazee fundees, creationism, secular humanism, scepticism (British English will pervade here, note) and rationality will appear on this new blog, to be known as Evil Burnee (because, you know, I'll surely roast in hell).

I shan't remove any of my previous posts on these subjects from witteringon, but I will repost them here.

Never thought I'd see the day... (repost from other blog)

I've read the UK edition of Computer Shopper from the very first issue, when it came on saddle-stapled newsprint and cost only 50p. Since the passing of all those fondly remembered home computers such as the ubiquitous BBC Micro and Sinclair Spectrum, and the not-so-ubiquitous Oric, Memotech and (one for the uber-geeks) Jupiter Ace, Shopper became -- and has remained -- PC-centric.

So it was with surprise bordering on disbelief that I spied this page of buying advice in the latest (July 2007) issue:



Look at that recommended PC in the bottom right-hand corner. If you think your eyes are deceiving you, here's a blow-up:



Yes, it's a Mac.

This tech stuff is too hard (repost from other blog)

I use three computers on a regular basis. My PC is a full-tower monster with two hard disk drives and two DVD rewriters. It's not new, and over the past few months it's been giving me grief (other than the usual...). But that didn't matter too much, as I've been enjoying using my MacBook since last June. I also have a G4 Mac mini, which was my introduction to OS X and the modern Mac. (I've had a second-hand MacPlus for a few years, complete with maxed-out RAM -- all four megabytes of it -- and the legendary programmer's switch, just to prove my genuine geekness.)

I have only one printer in use, an Epson Stylus Photo R300, and until last weekend it was connected to the PC. But as I said, the PC has been giving me grief -- refusing to boot until the box had been powered up for five minutes or so, and even then shutting down a second or two after turning on. Sometimes it didn't shut down, but just sat there shouting at me (yes, really, the damn thing actually spoke -- something about CPU test failure). Other times it would begin its boot-up sequence but then stop with an 'overclocking failure'. This I could cope with, simply going into the BIOS settings and immediately saving and exiting -- it would then boot up okay.

But as you can imagine, this was getting to be a pain, especially when I wanted to print something. The PC is on my home network, and that's how I printed stuff from the Macs. Recently the PC has refused to boot up at all, and I've had to wait until the next day. I had already done some research to establish what the problem was, and had decided that the most likely culprit was the power supply. My PC has a good ASUS motherboard and a decent graphics card, but the manufacturer really skimped on some other components. The keyboard and mouse were utterly repellent. I replaced the keyboard within a week and the mouse within a month. It seems the PSU was a similarly cheap unit, and replacing it with a Jeantech 600W unit completely solved the boot-up problems.

So I could again print relatively easily from anywhere on the network using the shared printer connected to the PC. But if the PC wasn't on, I had to wait for XP to start before anything appeared on paper. I had already looked at print servers some time ago, and nothing seemed suitable (or reasonably priced) until I noticed that Linksys made a USB Print Server with a 4-port Ethernet switch, which looked like a good deal. I read some reviews on Amazon and elsewhere that made me think twice -- especially the point about the status monitor not working, which would mean you could run out of ink and not know which one of the six cartridges to change. I then found the manual on the Linksys website, in which it was pointed out that it's in the nature of network printing that two-way communication with the printer is lost -- it's not specific to Linksys.

During the course of my deliberations the printer did run out of ink when I was printing from the MacBook, and I realised that because the R300 has a small LCD status screen, the software status monitor isn't strictly necessary.

I decided to risk the purchase of the print server, given its price. It installed okay, using the supplied setup CD on the PC, and it worked fine printing from the PC.

There's no Mac software provided, but how hard can it be? Answer: very hard.

Following Apple's guidelines for installing a network printer did not work. The best I could get was page after page of Postscript commands. Other times I ended up with page after page of garbage. Trawling various forum posts, and the aforementioned Amazon reviews again, led me to believe that very few users had managed to make this thing -- the Linksys PSUS4 USB PrintServer -- work with Macintosh.

However -- and this is the purpose of this post -- I did get it to work, from both the MacBook and the G4 Mac mini, and here's how to do it:

It shouldn't be necessary to use the Linksys setup CD, as the PrintServer has a web interface accessible from a browser, but I'm assuming your setup is similar to mine (Windows XP PC and Macintosh OS X Version 10.4.9 on a home network using a wireless ADSL router). Here's what to do:
  1. Install the PrintServer according to the Linksys instructions, using the supplied setup CD on the PC.
  2. Using the Linksys utility change the PrintServer to static IP addressing, choosing a suitable address within the subnet.
  3. On the Mac, open the Print & Fax system preferences pane.
  4. Click the '+' button to add a printer.
  5. At the top of the Printer Browser window, click 'IP Printer'.
  6. In Protocol, select 'Line Printer Daemon - LPD'.
  7. In Address, type in the static IP address you chose for the PrintServer, such as '192.168.1.8'. While you type, the Printer Browser will verify that you have typed a valid address.
  8. In Queue, type 'lpd'.
  9. You'll find that the IP address has been entered into the Name field. You can change this to something more meaningful.
  10. Location can be left blank.
  11. In Print Using, select the make of your printer from the list, then select the actual model of your printer from the model list, and click 'Add'.
  12. Close the Printer Setup Utility.
(I'm not certain all the above steps are absolutely necessary, but they worked for me.)

You should now have the network printer on the list when you next want to print something from the Mac. For me, this has worked on both the MacBook (Intel) and the Mac mini (G4 PowerPC). I can't vouch for any other set-up, but reading the tales of woe in the Amazon reviews has prompted me to make this post, to show that it can be done.

Tech, TV, Apple, DivX (repost from other blog)

I was fascinated when Steve Jobs announced the Apple TV. I like the idea of watching on TV media that has so far been confined to my computer.

There appear, however, to be a number of snags.
  • First, my TV is an old Toshiba 4:3 CRT with SCART and phono sockets. No way would the Apple TV interface to it without an expensive conversion box of some kind. But what about a widescreen LCD computer monitor? -- these can be quite cheap, even with a DVI input, and Apple are already selling reasonably priced HDMI-to-DVI cables. That might work. Maybe.
  • Second, some of the media I'd like to watch on my TV is intended for Windows Media Player, and I've installed various codecs into QuickTime so that I can watch this stuff on my MacBook. Couldn't I install these codecs on the Apple TV's internal hard disk? Highly unlikely. (I could transcode the files so that they play in standard QuickTime, but the idea is to make them easier to watch, not more difficult.)
But I've found a way to watch .avi files on my old Tosh TV.

Last week I bought from a local Argos Extra store, for £29.99, a Bush DVD2054DIVX DVD-player. So far it's played every .avi file I've tried in it, and I also found on the web a remote-hack to convert it to multi-region. It not only plays all my region 1 and region 2 DVDs, and my .avi files (whether on CD-R or DVD-R), but also mp3s and jpegs.

The 2054 is not listed in the current Argos catalogue or on the website. I went to the store to buy the 2051, which has an entirely different, compact form-factor. The 2054, however, is the conventional width, and fits better with other equipment. They told me when I paid that it might have 'some cosmetic differences.'

"Fine," I said, "as long as it does DivX."

Buying software for the wrong/right reasons (repost from other blog)

The podcast Security Now has been on my 'must listen' list for quite a while. Some podcasts I subscribe to are downloaded by iTunes, copied to my iPod and when they turn up in my "Unplayed" Smart Playlist I'll make a snap decision as to whether I'll listen or skip (this decision is usually directly dependent on the total number of podcasts in the "Unplayed" list).

But I'll always listen to Security Now. Steve Gibson knows computers. Not like some people know computers -- people who have used lots of software on several different machines, people who may have done a little scripting, or even programmed in 'C' or Pascal. Steve Gibson is familiar with the PC on a hardware level. His website, www.grc.com has loads of free Windows software utilities available for download. These are not the kind of idle utilities that someone thought up as maybe possibly useful, for someone somewhere. They are essential utilities that solve (and I mean solve, not just mitigate) specific problems with Microsoft Windows. I first came across Steve's utilities without knowing it. After suffering persistent pop-up spam windows on a new XP PC, I did a Google search and came up with something called "Kill The Messenger". I downloaded it, ran it, and have not been troubled since. At the time I knew nothing about Gibson Research Corporation, and didn't actually give it any more thought. It was only after listening to early episodes of Security Now that I went to the website and discovered I had successfully used one of Steve's free utilities several years ago.

Steve Gibson's flagship product is SpinRite, now up to version 6, and by all accounts is the world's best hard-disk recovery and maintenance utility. It isn't cheap, at $89, and some might balk at such a price for a download of only 170 kb. (Yes, that's kilobytes.) Remember, however, that Steve Gibson is 'old school' -- he programs in assembler, for DOS, so his utilities are really tight, fast and efficient. This is the ultimate low-fat software.

The Security Now podcast, part of the TWIT network, features Leo Laporte and Steve Gibson talking about various aspects of computer security, whether this is a comprehensive primer on cryptographic technology (and I do mean comprehensive -- this isn't something that you can give less than your full attention to; it's geeky in the extreme), or discussions on the underlying technology of something in the news -- such as the recent Sony rootkit debacle. Every fourth episode (which with typical geekness they designate a MOD 4 episode) is devoted to answering listeners' queries.

I've been considering buying SpinRite for a while, partly because Steve is providing a useful free service, not only via Security Now, but also to all Windows computer users via his Shields Up! website, and partly because if it's as good as everyone says it is, SpinRite will be a useful utility have instantly available. So today I purchased it.

A few months ago I bought a Maxtor 300GB external USB drive for my MacBook, and it began to regularly misbehave after being powered up for an hour or more. Apparently SpinRite is undiscriminating as to operating systems and file formats, and the recommendation is to extract the external drive from its case and mount it inside a PC before running SpinRite on it. Alternatively, it's possible to run SpinRite on a USB drive if the USB drivers are accessible by SpinRite, although this likely to be much slower in operation.

Well, I couldn't open the case, so I connected the drive to a USB port on the PC, just to see what might happen. I was surprised to find that SpinRite found the drive, and is now -- as I type -- doing its stuff. It will apparently take about five hours.

Watch this space.

Our own, our very own (repost from other blog)

At last, an intelligent, stylish and hugely entertaining science-fiction series that is, for a change, home-grown.

I refer, of course, to the Doctor Who spin-off series, Torchwood, currently airing on BBC Three on Sunday nights, followed with a BBC Two prime-time showing on Wednesday evening, plus various re-runs on digital throughout the week. The plots are utterly fantastical, but believable, thanks to the solid cast and the tight scripts, which show a respect for the main theme and arc of the Torchwood story (as much as has so far been revealed) that has long been missing from serious British SF. And make no mistake, for all its speculative unreality, Torchwood is serious adult stuff, about real people caught up in a world they are still trying to understand.

In the face of such epics as the new Battlestar Galactica and other serious SF from across the pond, British TV now has something to hold up and say, 'See, we can do it too!'

The rumours are true (repost from other blog)

Steve Jobs was very impressive in his keynote at WWDC, even if he did seem a bit flustered in the last few seconds.

So, OS X has been running on Intel for the past five years? And this doesn't mean that OS X will be available as an alternative operating system for Windows XP machines? Isn't OS X based on Unix?

Linux runs native on PCs so why shouldn't OS X? Even if it's not Apple's policy to make available an alternative PC operating system it seems to me that it's inevitable. Mac and PC hardware has been converging for years, and many software companies have a wealth of experience developing applications for both platforms. Apple itself has iTunes and QuickTime running on both. Will we soon see bootleg PC versions of OS X available for download from dubious websites? My guess is that these versions already exist, and the only way Apple will stem the spread of unofficial 'PCOSX' is to release an official version.

What Windows user hasn't envied the sleek designer efficiency of the Mac? (Okay, some Windows users say they never have, but they're lying.) The cool usability of the Mac is largely derived from its operating system, and the chance to sample it directly on cheap PC hardware could be too tempting to resist.

Just think: the release of a PC OS X could be the one thing that takes PC design by the throat and hammers some rationality into it. Currently the main authority on what makes up a PC is Microsoft. If Apple started publishing strict system requirements and hardware standards for PCs to run OS X, we might start getting better designed PCs that weren't so prone to crashing.

And amongst all this speculation let's not lose sight of the irony that the originator of the PC -- and therefore of all the clones that followed -- is the company that Apple are now ditching in favour of the 'heart of the PC'.
