Recently I sat in a room trying to write something on a Sony Vaio PC laptop which seemed to be running a special slow-motion edition of Windows Vista specifically designed to infuriate human beings as much as possible.
LOL
I don't like Apple products. And the better-designed and more ubiquitous they become, the more I dislike them. I blame the customers.

If like me, you are still using Windows on your primary PC or Notebook, and - heaven forbid - are still using XP, and you're not a fan of re-formatting and reloading the OS every time things get bit infected, or slow and heavy... Pause for breath... You're probably either just not interested, or , quite the opposite, you're fond of poking around the registry, tweaking and optimizing.
When I get a virus, trojan or other nasty, I like to remove it, clean up all traces of it, and kill off the previous System Restore point(s). I have Nod32, Xoftspy, Malwarebytes, Spybot S&D, Spysweeper and other tools to help me out in this regard. I don't do "re-format and rebuild" - not ever. You learn nothing, and you lose too much. It takes time to lovingly customise your user experience. Reloading XP might be quick, but all the little flourishes you add over months, even years, is definitely not.
The downside of all this, is that eventually, things start to slow down over time. It gets tougher and tougher to clean up the remnants of this and that. One by one, the applications, files, pictures, movies and mp3s accumulate until you're short of resources; CPU, memory and disk space.
So, you do your best spring clean and you look at what you can optimise.
This is a minefield... Many so called optimisations can do more harm than good, so it's best to stick to the few that are known to work well. Keep it safe, at least at the start.
Boot up - we all want that to be quick.
System readiness from logon - that's really important.
Application loading times - Firefox, anyone?
I'm not going to go through all the things you can do to improve performance, because this article makes a pretty good fist of that, but the most important thing to me to start with is boot time.
If you don't feel like using a tool like BootVis, you can always turn on boot logging and read through the boot traces. You'll be digging around for ages, but you'll learn a lot this way (I picked up a thing or two, anyway). You can really see where the bottlenecks are occurring, and can address them one by one. You can read all about this painstaking approach and try it out if you want. Another alternative is tracelog.exe, part of the Win XP SP2 Toolkit, which is described in detail in an article on citrix.com.

It's called Courier and it's beautiful
Some people are complaining because it's hinged. So it has a hinge? So what!?
Journals, diaries and binders have "hinges" - nobody moans about that.
Seriously - if Microsuck can deliver on this, I might just stop calling them Microsuck. This could single-handedly make up for Win ME, Vista and even Visio.

Most of the time I don't face issues with dropped connections, but recently I found myself in a situation where the signal was not so strong (no repeaters were located any where near me, and the access point didn't have a 5dB+ aerial). As a result, connections were dropping so often, that I was nearly driven mad.
Every other wireless device was fine, dropping either occasionally, or not at all, but my Lenovo Thinkpad T61 was, or rather the drivers for the Intel WifiLink 4965AG card were, quite frankly, performing pretty poorly.
In deperation, I visited the Lenovo site to see if there was any upgrade available. There was:
However, I realised from reading that page, that it wasn't going to be all that simple. The webpage lists a daunting number of prerequisites and caveats relating to model number, card version, current installed program versions and so on. So many, in fact, that I was beginning to get turned off.
Eventually, for me at least, it boiled down to this:
Note: The part numbers are listed so that you can find each component driver easily.
From the readme notes for Intel Wireless LAN (11abgn, abg, bg) - 6hwc05ww.exe:
Make sure that the following driver prerequisite were installed on your system before installing this driver: - MSXML6.0 Parser or higher - Windows Installer 3.14 or higher (Download installer from http://www.microsoft.com)
- If you use ThinkVantage Access Connections, the following software must be installed. - ThinkVantage Access Connections for Windows XP/2000 version 5.1 or higher - ThinkPad Power Management Driver for Windows 98 SE/Me/2000/XP/Vista version 1.51 or higher or ThinkPad Power Management Driver for SL Series version 1.44 or higher - ThinkPad Hotkey Features for Windows 98/98 SE/Me/NT 4.0/2000/XP version 1.24.0603 or higher or Hotkey Features for Windows Vista/XP/2000 version 2.09.0002 or higher (Note: Refer to each Hotkey package for which version to use.)
- If you currently use IEEE 802.1x authentication on Windows XP Service Pack 1 and do not use WPA encryption, Lenovo recommends you to uninstall Q826942 (WPA Supplicant update rollup package in Windows XP) and Q815485 (WPA Wireless Security Update in Windows XP). This does not apply if you are running Windows XP Service Pack 2.
To check if Q826942 or Q815485 is installed and to uninstall it: 1. Start Windows XP and logon with administrative privileges. 2. Click Start and then click Control Panel. 3. Click Add or Remove Programs. 4. Click Windows XP Hotfix (SP2) Q826942 or Windows XP Hotfix (SP2) Q815485 if it is listed under Currently installed programs. 5. Click Remove and follow the instructions on the screen.
Note: The above action will remove all the fixes within the update rollup package, Q826942. You may need to re-install the other specific hotfixes you expect for this rollup package.
- You may need to re-enter security information after updating the Wireless LAN driver.
- If you use Single Sign-On with the following authentications, ThinkVantage Access Connections version 4.22 or higher is needed. - LEAP on Windows XP
- [Specification changes] 2200BG/2915ABG Network Connection will report lower signal strength than with previous driver versions. Because the 2200BG/2915ABG methodology was changed to be more accurate and responsive, similar to the 3945BG/3945ABG. However, wireless network performance and functions are not affected at all by this change.
I don't know about you, but I find even the readme a little bit discouraging.
So from the notes, check you have the right MSXML parser 6.0 +, and the latest Windows Installer, and from there:
Switch off wireless radio (use the hard switch to be sure it's not going to come back on)
For the T61 with the 4965AG WiFi card:
Install the following parts in this order:
You will have to restart after each install. Make sure you do this. Messing this up is not an option!!!
Note: you may find that you are already at some of the minimum driver / program levels, but still look for the latest for your platform. For the Vista versions of the drivers above (points 3. and 4.) visit those pages and you'll find the link to the page for the Vista drivers / programs.
So, after doing all this, how was the performance of the new wireless adapter driver?
In short, pretty much perfect. Not one droped connection, and even a 40% signal could be used to get acceptable transfer speeds (18-24Mbps out of a possible 54).
What was an added bonus wass that the new Access Connections program is pretty cool and flashy. It's still the same underneath, but there are some extra features. I won't spoil the surprise for you in this post. Maybe later.
If you are suffering at work or at home from all-to-often dropped connections (and I know many of you are), you could do a lot worse than upgrade. Your sanity will thank you for it.

Well, no need to guess. ManicTime is a handy little freeware utility that allows you to track your time spent on your computer, by program, and your idle time too.
All this information is stored in a local database, isn't transmitted anywhere (for those with security concerns, rest assured), and can be displayed in all manner of views, graphs and charts. It's not a mindreader, so you might have to tag your time, but that's pretty easy.
It might not be something you'll use often, but it's interesting to give it a try at work, you might be surprised just how much you spend time switching applications when you see the results, not to mention the surprising amount of downtime. An eight to ten hour day doesn't amount to as much real work as you might think, especially when you take away the time lost to meetings, lunch, coffee breaks and other meanderings.

If you haven't used NMap before, here's what it does in a nutshell:
NMap is short for "Network Mapper", and it is used to determine what hosts (computers and other network-enabled devices) are on the network, what services they offer (apps), firewall and AV or filtering they have installed, plus OS type and version.
It's obvious to see the benefit if you're a network administrator. Just start it sniffing on the company network and it will report back all this information, allowing you to do inventory, security compliance audits and vulnerability testing.
Of course, the more subversive of you out there will probably think other uses. Whether your hat is white or black, you can have a lot of fun with this. Sniffing for hosts to attack, or just to play about with is easy and rewarding. However, I wouldn't run it on a tightly-controlled, corporate network unless you're really tired of your job ;-)
The latest version is NMap 5.0. It came out in July, and unfortunately no-one told me until now :(
I upgraded my not-so-old 4.75 version on my Win XP machine, but I haven't done the same for my Ubuntu box. Zenmap, the front-end, looks slightly tweaked, and overall (I might be imagining things, it's not as if I benchmarked it) it seems to run faster.
If you haven't tried it, maybe now is a better time than ever. Considering what it does, and how powerful it is, it really isn't much of a hassle to install and configure. It has a really great tutorial, and the NMap site it a treasure trove of tools, tutorials and ideas. It's well laid out too.

OK, it was 40 years ago a few days back... But it's still hard to believe that Unix is really that old. I still don't know as much about it as I'd like.
I know, this isn't exactly news, but if you haven't upgraded to Firefox 3.5 by now, you probably should - and I think you'll be pleasantly surprised.
All the good things that made the majority of users choose Firefox (other than those who just blindly accepted IE because they had no idea how to do otherwise) are still there. But there are a few new features. Some are new (native JSON support, web worker threads), and some are just new to Firefox (private browsing). Other features were available in add-ons, such as Tab Mix Plus and Session Manager (closed tabs, closed windows, tab tearing).
These new or borrowed features are important factors that will contribute to Firefox staying ahead of the competition, but I think I'm not the only one who was starting to get tired of every bell and whistle slowing the browser down. Safari wasn't going to tempt me away, but Chrome - while it didn't impress at first - started to really grow on me. Thanks to Chrome View, I could set certain sites to load up in Chrome instead. I'd noticed that Firefox 3.0.x, while it felt like an improvement at first, seemed to have terrible trouble with sites with deeply nested links. It simply took a ridiculously long time to load such sites, making the browsing experience pretty unbearable in the process.
So, the main area for improvement for Mozilla to look at, for me, was speed. Chrome and Safari had it. Chrome had some neat features too (even if Safari had nothing), but it had no add-ons (and probably never will). Once I heard that Firefox 3.5.x was much faster than Firefox 3.0.x I was very nearly sold. It was just a matter of time before all my favourite add-ons were confirmed compatible with 3.5 and then I'd be on my way.
My favourite add-ons (all FF 3.5 ready :) - Ad Block Plus (essential) - Greasemonkey (essential) - Personas - Tab Mix Plus (quite redundant now though) - Selenium IDE (essential) - Flashgot - Firebug (essential) - Speed Dial (essential) - Stumbleupon - Forecastfox - Zemanta
Now that I have upgraded, since all the add-ons listed above are supported, I can vouch for greatly improved performance. The claims from Mozilla were that FF 3.5 is over 2x faster than FF 3.0, while benchmark tests on many sites claim it's up to 2.5x faster. All I can say so far is that I can feel a huge improvement. Most of the frustration has been removed, and I don't think I'll be reaching for Chrome quite so often from now on.

Cowon's new flagship offering looks fantastic, but then again, most of their products do. It features a 3.3" screen and it looks like it will be extremely high def, with perfect colour. That seems to be the main improvement (maybe the UI and controls were made more intuitive), because the sound quality is exactly the same as the models that have been available for the last few years: 20Hz - 20kHz freq. range and ~30mW per channel max output @ 16 Ohms I suppose it doesn't need to be any better than that for consumer use - but they could easily take on the pro market if they wanted to.
It has a lot of nice additional features: flash playback, wireless, bluetooth, AV output in PAL/NTSC - I wouldn't mind some of that. Pity they never did anything about the recording facility. This seems to be the only thing missing - a really good stereo condenser mic instead of a pinhole, and a good sampling bitrate (say 160kbps - 320kbps mp3, instead of 96kbps WMA). With that, musicians (and bootleggers ;-) wouldn't need the Zoom H-2

Cyxymu, a Georgian who has blogged extensively on the Russo-Georgia conflict and the land grab of South Ossetia was apparently targeted in a DoS attack lasting around two hours yesterday.
His Live Journal blog (which I won't link to), Facebook page and Twitter profile were hit hard, probably by a botnet set up to silence him.
The side effect of the DoS attack was that Live Journal, Facebook and Twitter were heavily affected, with Live Journal an Twitter being brought down, unable to handle the millions of requests, while Facebook performance was greatly reduced. Google and YouTube were also targeted, but their architecture greatly limits the effects of such DoS attacks, so they were able to absorb most of the impact and no end users were impacted.
It is not yet known who was responsible, although there was the suggestion (from Cyxymu himself) that the Russian authorities were involved. There is more evidence that an individual or a small group was responsible, leveraging the power of hacked PCs (known as zombies) around the world to stage what is quite a traditional type of denial of service attack - flooding target pages with a very high and volume of requests, sustained for long enough to bring down the site or service serving the page.
Cyxymu's Live Journal blog is still offline - presumably as a precautionary measure from Microsoft, to spare other users from further outages. Understandable, if a bit cowardly.
Whether the KGB was behind this, as some suspect, or if it was a disgruntled diametrically opposed (in the political sense) hacker or group of hackers remains to be seen. It is unlikely that this is the last we will hear of it.

I don't use the .NET 3.5 framework myself, I'd rather stick pins in my eyes, but for those who do: watch out for fix pack 1 - it'll open up a security hole. The vigilant will probably notice that you have a new add-on in Firefox that can't be uninstalled without some registry diddling. I'm sure it'll be patched some time, perhaps next month.
Of course, if you're one to install the .NET framework in the first place, you're probably not the type to check these things.

A couple of months back, I posted this about Bitnami. They provide applications such as Drupal, Wordpress or phpBB to be installed natively on a PC, Mac or Solaris box with no existing web application infrastructure stack in place - all in one convenient installation file, providing the complete package: a full-stack infrastructure with the application of choice as the cherry on top.
This makes the whole process of getting a blog, CMS, bulletin board or portal set up as easy as possible. All you need is a modest box to serve it to the company, or to the world at large.
Of course, if you don't have a modest box (a server, in other words), you're stuck. Hosting a public application can be a headache, and there's a cost involved, which can grow as your application scales.
Why not take one of these Bitnami stacks and put it in the cloud? There are lots of cloud providers out there, that will provide you with a scalable site with an application, configure it, manage it, load-balance it and monitor it for you.
Enter Bitnami and RightScale, linked with Amazon's cloud offering. RightScale will give you 10 hours free cloud computing with Amazon EC2, after which further costs are linked to your EC2 account.
I'm not the biggest fan of cloud computing, yet, but if you have a business that needs a public facing site, and you want to put the responsibility of running it firmly in the hands of people that know what they're doing, then I can see how this could be a great solution.

A few weeks back, when IBM turned down Sun's offer to acquire them, I thought they were crazy. You would think they would at least try to block their main competitor, right? Wrong. Oracle have been busy doing some buying of their own of the last few years, gradually building up momentum, looking for a big name acquisition.
Weeks have passed, and it's still hard to say what the future will hold for Sun, and for Oracle. While in the past they have been pretty much steamrollering the smaller companies they've got their hands on, a company of the stature of Sun - who gave us Java and Solaris - requires different treatment. This should be an alliance, a meeting of minds.
However, what makes this approach even more interesting, is that Sun only recently acquired Oracle's greatest open source competitor, MySQL.
Now it's personal. Reading around on TheRegister and Slashdot, amongst other places, I'm getting a bit worried. I actually care about MySQL. I've been using it since I started to work with databases and especially since I started to develop web applications. It's default beep, sounding every time I type something stupid into it's command line, is music to my ears.

For those who have been waiting for Sony's strategy of flogging over-hyped, overpriced products for years to catch up with them, this is very, very good news. For the 16,000 unfortunates who will be losing their jobs over the next year, this won't be such a welcome development. Samsung make better TVs, Apple make better personal music players, Nokia make better phones, Nintendo make better games... Shall I go on? Sony nowadays are the definitive jack-of-all-trades, master of absolutely nothing. Good to see them pay the high price their foolish customers usually do :P
