Debian security updates for testing branch

So I decided to install a full anti-virus and Spam filtering system on my web/mail server using Amavisd-new/ClamAV/SpamAssassin. This has gone pretty well especially since I’m using the Razor plugin for SpamAssassin.

Razor is like a collaborative network of machines which hold signatures for spam that is currently circulating around the Web. Each time I receive a mail into my system, a unique signature is generated for it and this signature is checked against the signature database in Razor servers on the net. This catches so many spam emails it’s not funny. On certain days I Razor catches 77 spam messages and all my normal emails are untouched and end up in my inbox. Razor is a true lifesaver.

ClamAV is also pretty good at catching viruses in email. It just scans each mail as it comes in and if it’s infected, puts it in ‘quarantine’ and sends the admin an email about it. Very transparent and it works nicely.

The only downside to all this was that I had to pull some packages from Debian’s ‘testing’ branch which may not receive timely security updates. I didn’t think that I could rely on ‘testing’ to give me timely updates and this seems to confirm it. The official word seems to confirm this as well. I guess my only choice is to add:

deb http://security.debian.org/ testing/updates main
deb http://security.debian.org/ stable/updates main

to the sources.list file and hope I get timely updates from both.

Finally on Wireless!

I know I’m late to the game, but I’ve finally got a wireless network installed at home. I got myself a Belkin Wireless ADSL Router to replace my current ADSL router. The router itself was easy enough to set up but unfortunately setting up XP to use the wireless network was a nightmare!

I tried so hard to make XP use my wireless network to no avail. Due to some bug in the Service Pack 1 release of XP, it was continously creating some kind of bridge for me between all my networks. I had to figure out that I don’t need the bridge and once I had that sorted I tried to get wireless working again. I couldn’t get it to work with WEP encryption and so I opted for the WPA-PSK method which I’ve read is better as it fixes some older attacks which WEP was vulnerable to.

For those interested, I tried the using the network without encryption in linux and it worked straight away! What a surprise and a breath of fresh air! I’m using Ubuntu Linux nowadays by the way. It is a Debian based distro which has it’s own packages which they update around every six months or so. It’s heavily GNOME-based but looks quite good so far. Sleeping the laptop and other ACPI-related stuff doesn’t all work yet, but that’s pretty much how it is with all new Centrino-based laptops nowadays so I’ll just have to wait probably about a year or so before all that is sorted out in Linux (I mean done for me automatically without recompiling kernels, not that I mind the occasional kernel recompile ) :-)

BlogBridge

A superb blogging app written in Java, and it also allows you to save your state so you can pick up where you left off on a computer other than your regular one. Just try it using the supplied Webstart link; you don’t need to create an account the default list of supplied feeds is excellent.

Some cool stuff on the Ars Technica Holiday Gift Buying Guide. Mmm.. iPaq ;-)

Superb commentary and speculation from Russ on the iPhone ;-) This sounds plausible, but a lot of the comments against it also make sense. Apple will have to compete in the market that is already swamped really badly, and they will also have to deal with the mobile phone operators. In short, a lot of work in a lot of new territory for them, if they take up the challenge.

weedshare

Finally, music artists have come up with a way to earn money and circumvent the music industry through weedshare, and online service that allows artists to put up their own songs and charge as much as they want for them, but usually up to a dollar for a song. I think it’s a great idea, if it takes off that is. At least artists now seem to be starting to move towards a model where they make their own rules and earn their own keep on their own terms. Also, the more you share and other people share the better. This is better explained in this section in the FAQ:

The concept is pretty basic: Weed rewards people who share files and respect artists’ rights.

You can play a Weed file three times for free on any PC. After three free plays, you’re asked to pay for the file. You can use any current Windows Media-compatible player software to play the file. The Weed software, which keeps track of your account information, is used to purchase files.

Once you purchase a Weed file, you’re free to play it all you want on up to three PCs. You also can burn the file to CD and play it on your stereo system, or transfer it to a portable device like the Creative Labs Nomad, the Rio S10, or any current Windows CE PDA.

Best of all, you can share Weed files with anyone you like, as long as the files remain in their original form as Windows Media files. And if someone you share a file with purchases that file, you’ll earn a payment for helping to distribute it.

Specifically, the artist always receives 50% of each sale, and the rest goes to those who helped distribute the file. You get 20%, the person who shared the file with you gets 10%, and the person who shared the file with that person gets 5% of the sale price. Weed receives the final 15% for service and software maintenance costs.

All purchases and distributor payments are made into your Weed account through PayPal. Deposits and withdrawals from your Weed account cost 50 cents, but all other transactions are free. You must have a PayPal account to make deposits to your Weed account.

Some friends were over and I took some pictures of their baby daugher which they loved. My Olympus camera is over 3 years old right now and this got me thinking about what new stuff is available. I bought my 3 megapixel Olympus camera for about 300 pounds and now the superb Canon IXUS 5 Megapixel is only 239 pounds! It’s quite an amazing camera, more than good enough for a lot of things. A great recommendation.

Spyware removal guide

Great guide at Ars Technica here about the best tools for removing Spyware from your computer. I already use Ad-Aware SE 6 and it gets a really good score so I’m happy.

Never heard of the SqueezeBox before. Very interesting.

I completely forgot to post about the Regent Street Apple Store opening in London last weekend. I wish i could have gone, but I would have had to queue all night in order to ensure I got a goody bag (worth £700). I will go soon anyway, and here’sa good summary of what went on there

Upgraded to MT 3.2

I finally upgraded to MoveableType 3.212. I really wanted to upgrade, if just to get the Comment Moderation feature as comment spammers are bombarding my site pretty badly right now. Everyday I get about 20 pieces of new comment spam. This feature allows me to approve comments from unregistered users before they appear on the site. That doesn’t cut down the work for me, but at least it defeats the spammers’ purpose: free web advertising through search engines like Google.

I haven’t been reading blogs regularly these days and I just found out that Russell has started working for Yahoo!. Wow! Way to go! I have always enjoyed reading Russ’ posts (sometimes not completing them as they tend to be really long :) and I’m looking forward to any changes at Yahoo! that he will influence. Good luck, Russ. On another note, this image he has put together of the phones available in the US this Christmas is awesome.

Tracking everything you print?

I’ve got to check this out on my own printouts, it’s interesting: Color Laser Printers Tracking Everything You Print.

It’s not new, but it’s getting noticed: Jordan writes “Yahoo! News is
reporting that several printer manufacturers are now and have been for
some time embedding (nearly) invisible serial numbers in every document
you print with their color laser printers, allowing law enforcement to
track any such document back to the printer which printed it. The
technology, ostensibly created to track down money counterfeiters, was
created by Xerox about 20 years ago. A Xerox researcher says that the
number-embedding chip lies ‘way in the machine, right near the laser’
and that ‘standard mischief won’t get you around it.’”

I have suddenly gotten a surge of mobile mania in the past few days. I bought a Sony Ericsson T610 a few days ago and though I really like the phone (it’s my first GPRS phone) I really wish I could have gotten something better. I will soon try and switch from pay-as-you-go to a contract with either T-Mobile or Orange, which will allow me to get much better, newer phones, plus an option to pay a fixed amount for a certain amount of GPRS usage. As it is right now, I’ve tried to use GPRS on it a bit and it really eats up money like no tomorrow. I wish we had unlimited GPRS here in the UK at a cheap rate like in the US and elsewhere :(

I’m thinking about getting a iPaq handheld and a WiFi access point so that I can surf wireless on the PDA. I used to do a little blog reading on my older Clie, so I think it may be OK reading websites on it, but I’m not sure. It will certainly be useful when out and about though, I can use my bluetooth phone’s GPRS connection if I can’t get WiFi access.

Star Wars Trilogy is out!

Hmm.. Russell just received his Star Wars trilogy set, I feel like I should get it too, it was just 29.99 at WHSmith’s on the day of the release and is only 26.99 on Amazon right now. I was seriously expecting it to be much much more expensive than that, though I am glad it isn’t. I never managed to watch any of the movies as a kid, they were never to be found anywhere. It was only about 7 or 8 years ago when I was in Cyprus that I watched them properly. I do believe the new movies suck though Episode II was definitely better than I.

I almost completely missed the rumour that Google is thinking about creating it’s own browser, namely gbrowser. That should be interesting, though I still haven’t managed to get a gmail.com account. Google has hired away a few people from Microsoft who used to work on IE. Jason Kottke has more on it, and apparrently Anil Dash thought it was a good idea last year ;-) Good call.

Good Security Checklist

Kasia has compiled a good security checklist against the recent spate of ssh attacks. If you don’t know about this attack, read your log files, particularly the auth.log files and if you see repeated attempts to login as root, guest, test, etc then someone is trying to break into your system.

Take a look at her checklist here

MSN Music and the iPod

Regarding my comments on MSN Music and the lame comments by some people, Daring Fireball has made some interesting observations on the help site for MSN Music. Microsoft claim that Apple’s store uses a proprietary format and it is difficult to use the store with the 70 other standard music players on the market. Interesting spin, though as is pointed out in the post, those 70 or so other players also work only with WMA or MP3. In the case of Apple, the iPod only works with AAC and MP3. So both are DRM-encumbered, but, Microsoft makes a really big spin on it and makes the iPod look like the beacon of incompatibility.

The only format of music you can buy on the MSN Music store will be DRM-enabled WMA. Most players that support Windows will play only this format plus maybe MP3. The MSN Music store only works in IE and uses ActiveX. So who’s being incomptible with everyone else here? Apple makes iTunes available for both Mac and Windows and people have even been able to play the stuff in Linux as AAC is a standard format, unlike WMA which requires you to get the Windows DLLs from somewhere to play in Linux. Anyways, enough of this rivalry. They both have their limitations and lock-ins. Let the best man win. I have a feeling Microsoft might eventually take the lead again somehow because they have deeper pockets and most people who get Windows with their PCs will not know any better to go out of their way to buy music from Apple. Yes I know Apple is the leader in online music sales right now, but for how long?

I uploaded a bunch of older entries from my weblog yesterday and it is really striking to me how much more funny and free-spirited I used to be back in 1999 :-) Staying awake everyday until 3:00 am, reading a lot of technical books, documentation, eating a lot, watching a lot of movies. All my older entries have a much funnier streak. I hope I don’t lose what I have left as I get older.

MSN Music Store

I haven’t tried it yet, just browsed around a bit looking for songs by Billy Joel and Pearl Jam, for instance and I did find both. I had to wait quite a while for iTunes to add Billy Joel and Pearl Jam still has a paltry selection on iTunes from what I can see so far.

Robert McLaws loves the new music store but says several things that just don’t make sense, first of all why the fuss about iTunes being a fat client versus the web-based MSN music store? I love the iTunes interface and the way that Apple have integrated song playback, cd burning, music purchasing, etc into the client is just seamless. I also think the quote about having to download the fat client is useless as it’s really no big deal to download it and it installs without a hassle. If he’s complaining about people who are on dial-up or something like that, then I don’t think they will have a lot of fun downloading music in the first place let alone iTunes.

One of his other points is that Apple is locking in customers to it’s proprietary AAC format. First of all AAC is NOT proprietary. It is based on an established and openly published standard (mp4 i think I haven’t checked). The DRM aspect of Apple’s AAC is something that Apple have themselves added to it to please the music industry. So who is the proprietary format here? WMA!! Windows is really the one that is locking it’s customers into a proprietary Microsoft-only format.

I’ve also read that songs purchased from the MSN music store will be 160 kpbs VBR (variable bit-rate – which is good). This has been used to assert that since Apple’s AAC is only 128 kbps, it must be inferior, but this is not the case. These codecs are different and even though 160 is a higher number, it is still possible for Apple’s AAC to sound just as good as WMA. The only way to really find out is to listen to it in person and from what I have heard from the Apple store so far AAC sounds absolutely superb, but we’ll see about WMA, I will try it out soon. I don’t think I will be able to tell much difference personally.

Note that I’m not anti-Microsoft, it’s just that I think those comments by Robert are way off. MSN Music doesn’t even have Audiobooks yet or Gift Certificates for kids or even iMixes. I do have a feeling that Microsoft will catch up soon, though and then perhaps once again Apple will have innovated only to have someone else out-do them. Is it possible? Yes, very, but only time will tell.

20 years

Larry Osterman has written a brilliant post about his 20 years at Microsoft. He’s been through so many changes and reorganizations at Microsoft, he’s basically witnessed the whole of the personal computer revolution and it’s repercussions. I suppose a lot of others have as well, but in any case his write-up is superb:

I still have the letter that Microsoft sent me confirming my job offer. It’s dated January 16th, 1984. It’s formatted in Courier, and the salary and stock option information is written in ink. It’s signed (in ink) by Steve Ballmer. The offer letter also specifies the other benefits; it’s not important what they are. I also have Steve’s business card his job title? VP, Corporate Staffs. Yup, he was head of HR back then (he did lots of other things, but thats what his title was). I also have the employee list they gave out for the new hires, as I said before; there are only about 600 people on it. Of those 600 people, 48 of them are still with Microsoft. Their job titles range from Executive Assistant, to UK Project Troubleshooter, to Architect, to Director

Discovered Metroblogs today, and I quite like the London one, despite all the criticisms levelled at it in the comments. I’m sure it’ll improve in time. It’s made me think about going to the London Wetlands and the Thames Barrier Park.

Torrential downpours

Middle of summer and so much rain around it’s not funny. I was caught in a thunderstorm a week ago with an umbrella in one hand and a kitchen trolley in another :) Oh and a knapsack which I shouldn’t have brought along. Nevertheless running in the rain and hoping and praying that the lightning flashes you are seeing don’t find a reason to come your way is something I won’t (and won’t want to) experience again soon. I should have had the damn trolley delivered ;)

That was a while ago but recently even more torrential downpours have hit the northern areas of Scotland and England. Lots of flooding and devastation and rescues. Charlie is causing much havoc stateside as well. We have mostly managed to avoid the rain here is london so far but we hear it is approaching ….

Had a really nice time a few nights ago with my friends Phil and Julia and Carlos and Jenny. They were hosts at our first tea party at the new flat. Muchos fun was had by all.

Apple Tablet coming up? new G5 iMacs being released end of August, which should be very interesting. I can’t wait to see their new design for the iMacs as I’m sure everyone else is. Phil Schiller is doing the keynote speech this time though as Jobs just underwent cancer surgery. I wish him a speedy recovery.

XP SP2 install not trouble-free

Looks like XP SP2 is definitely better but proving quite troublesome for many people to install. I’ve read quite a few reports of installations failures and total system screw-ups on different mailing-lists and newsgroups, and this eweek article gives a nice summary of the problems so far:

In Weblog postings and interviews with eWEEK.com, users have reported everything from unproblematic installs to complete system failures. In between, difficulties varied from confusing user interface changes to broken applications to performance slowdowns. Many said SP2′s features improved their confidence in the platform’s security; others said they continue to be surprised by minor issues

The thing that surprised me most was the ability of other firewall vendors such as McAfee and ZoneAlarm to turn off the XP firewall when they are installed. I understand why they would need to do this, as running 2 potentially conflicting firewalls at the same time is probably not a good idea, I do hope these third-party products provide suitable notification and warning of their actions.

I myself am actually a bit glad that these kinks will be worked out or at least solutions will have been posted for most problems by the time Microsoft releases the non-OEM home user version of SP2.

On another random note, though and totally unrelated to SP2, Pizza Hut in London sucks! And I really mean it, I almost lost it today trying to order a simple delivery from them. The person on the other end couldn’t understand my address, had problems with my postcode, the final price was wrong …. I’ll just end it there, I hope they get better

Great Hackers

Found a great entry on Tom’s site today where he comments on Paul Graham’s excellent Great Hackers essay. I haven’t managed to find time to read the essay but Tom’s post about office space makes a good point. I also strongly believe in having a nice quiet space when one wants to concentrate on ‘hard problems’ or even when trying to follow a train of thought to conclusion. Being interrupted at times like these leads to a huge loss in productivity as you have to context switch for however long is necessary to do something else and when you return to the task at hand you might find it difficult to continue where you were interrupted. It’s not like you can simply change the Instruction Pointer in the brain like you can in computer memory to simply resume execution where it left off :-)

If you read Ray Kurzweil’s book The Age of Spiritual Machines you’ll see that he is right when he states that brain neurons basically waste a lot of processing power not calculating, but sustaining body functions. So when a positronic brain is eventually constructed with equal computing capacity to the brain it will function much more effectively at computation as electronic circuits are a million times faster than neurons. Remember though that this “being” or whatever it may be will also have to devote a portion of it’s processing power to maintaining itself. Still, in the end it would be a lot more efficient.

Finished the Move

Just finished moving home a while ago and I’m glad it’s almost over. It’s always quite stressful and deeply tiring sometimes; often there are days when you just want to relax but there’s another box to unpack and flat-pack and discard. Then you hope the garbage guys feel like picking it up ;-) They only picked it up this Saturday after a full week of flat-packed boxes lying there.

We had to buy some cupboards and stuff from Argos, and are currently into our first few days of a Sky Digital subscription. The fact that we can find something to watch most of the time now is still something to get used to. There is always something, maybe Simpsons, Enterprise, X-Files or Frasier or something to watch. Most of the time it’s several things clashing with each other. Let’s see how we cope with that.

In other news, XP SP2 just came out and I’m so glad it finally did. I’m waiting for the version for home users to be release before I upgrade but I am so glad Microsoft is finally fixing it’s mistakes and making XP more and more secure for everybody. Let’s hope this really does fix *most* of the problems that caused viruses and trojans to spread. Time will tell.

On-demand books

Pretty cool idea here about a device that prints books on-demand.

A user browses through books by “author, title, subject matter or publisher.” Once they have made a selection the book text is sent to the machine via satellite and the whole thing is printed out in standard-format softcover in three to five minutes, basically turning the whole book browsing and purchasing process into an ATM transaction.

Firefox on my laptop seemed to be scrolling funny, generally being quite slow when scrolling up or down. The increments seemed to be so small they caused visible ghosting to occur. I was worried this was a problem with the laptop refresh rate until I tried the same page in IE which seems to scroll better and in larger increments. SuperScroll fixed this for me. It allows me to specify the number of lines to scroll by, and this helped me mimick IE’s scrolling behaviour perfectly.

Blog Software Breakdown

Big kerfuffle happening since MT decided to impose some charges upon its users. Mark Pilgrim has a very well-written piece called Freedom 0 which has been linked to death by many people; he ended up writing a follow-up to it. There is a nice breakdown of most blogging software and their features here

I’m still using MT as I installed it last year. Since I’m the only one publishing to this blog at the moment, I don’t see any reason to change over to anything else. Nevertheless I will keep a close eye on WordPress and may switch to it sometime in the future as Tom and many others have done. It’s not that I’m against what MT have done in any way; it’s just something I need to think about.

Been doing a lot of linux work lately at home and am quite pleased with its progress on the desktop ;-) Kernel 2.6, Gnome 2.6, gdesklets, etc all make for a really nice desktop and OpenOffice is getting better everyday. The GNOME developers are quite busy these days as can be witnessed by reading the PlanetGnome blogs.

Serious OSX exploit!

A very serious exploit has been discovered on OSX, and everyone using Safari or any other browser on OSX (even FireFox or IE) are urged to follow the instructions here so they can temporarily stop the exploit from working, at least until Apple gets its act together and fixes the problem. The fact that Apple have still not fixed the problem, which they have been aware of since February strikes me as a very stupid thing to do. I don’t know if fixing the exploit would require many in-depth changes to the OS and maybe that’s why it’s taking so long for Apple to fix. One would hope that this is indeed the case. They should have at least warned their users about this a long time ago. Leaving an exploit unpatched like this for such a long time looks really bad for them, especially in enterprise environments where I hear they are trying to make serious inroads.

It seems the HFS+ file system on OSX is quite good at keeping file fragmentation at bay, almost eliminating it altogether in most cases! Amit Singh has a great article about it here.

A colleague at work asked me today how OSX’s Mail.app does it’s spam filtering and this appeared as if just by coincidence :-)

Created by the engineers who bring the Japanese input method and the Speech technologies to you, Mail’s junk mail filters are outstanding. When trained for a sufficient period of time, the filters can reach 98%+ accuracy against spam and are surprisingly painless to use. In fact, this feature alone has convinced many users to switch to Mail.

The first part of that article is also pretty good, a lot of good stuff about spam, picking good email addresses, etc.

Update: These guys have released a program to fix the OSX exploit.

Sony Clies, Mac x86 emulation

Some amazing things happening these days. I’ve been using my Sony Clie heavily for quite a while now and have found it to be so convenient while travelling to/from work. I’ve got several ebooks on it (including Cryptonomicon :) , some music and some technical audio talks, some movies, a few pictures I took in the office, and every morning I sync up all my RSS feeds to it and read them on the way to work :-) It’s got quite a good battery life, requiring recharging every few days or so, depending on how heavily I use it.

The only downsides to using a clie on the Mac is that some things like Memory Sticks don’t show up on the desktop as mountable drives. This can be fixed by downloading the excellent missingsync for macs, which allows you to use the full functionality of the clie, along with iTunes, iPhoto, etc. Memory sticks are one of the things I don’t like about Sony machines though. They are expensive for the amount of memory you get (about 50 pounds for 128MB – official sony store prices are about 70 pounds!). Yes, ebay is your friend :)

In other interesting news, someone’s written a Mac emulator for the PC that runs OSX! I’ve only just found out that PC fans are falling all over themselves to try this thing. There’s even a website called www.emaculation.com!

One other thing to check out: musicplasma. It’s really cool.

Hourly doses of coffee beat a cup? I better figure this out and change my daily dose, this might be quite helpful.
