So I went ahead and got myself a Compaq Presario B1256TU notebook computer for use as my mobile workstation. The retail package did not include an operating system (that’s why it’s relatively cheaper), and so while paying I was thinking whether to:

• Install Ubuntu Linux as my primary OS,


• Install a bootlegged copy of Windows XP or Vista.


• Purchase an original copy of Windows Vista.

A new copy of Windows XP was out of the question, since in my mind this is already a dated OS. Sure, it’s more reliable than ever, given the seven or so years since its first release. But seven years? That’s old!

Ubuntu, meanwhile, is cool, but sometimes I still find the need to run Windows apps that simply cannot run on Wine. So this could perhaps be a hobby OS. I do run eeeXubuntu on my Asus Eee, though. And so my wife and I decided to go for Vista, so we can have some exposure to some new OS at home.

And so we bought a copy of Windows Vista Home Premium to go along with the laptop. The shop gave us a discount with an OEM package (I wonder if it’s legal to bundle a separate OEM package with a laptop sale, though). I also asked for a copy of the HP-Compaq drivers for the B1256TU, as I also read that while drivers are available from the HP site downloading can take some time.

Our home is now a multi-platform one, with a Mac that runs OS X Tiger, a notebook that dual-boots Windows XP and Ubuntu Feisty (due for upgrade soon), an Asus Eee that runs eeeXubuntu, and this new Presario that now runs Vista.

The Compaq came packaged with 1GB of memory, though, and from what I’ve read 1GB is inadequate for use with Vista. But the first few days I was using the laptop, it was responsive enough. I noticed a significant improvement when I plugged in a 4GB SDHC into the built-in card reader for use with ReadyBoost, which basically uses flash memory as cache. This is faster than having to access virtual memory from the hard drive, whenever physical RAM runs out.

But then I was planning to use this machine for photo manipulation and some video editing. So I replaced one of the 512MB RAM sticks with a 1GB one (not able to find a 2GB stick yet, and because the sales person mistakenly told me that Pentium Dual Core machines only supported up to 2GB RAM). Some improvement. And when I found a 2GB stick cheap enough (PhP 2,000 flat for a Kingston branded one), the laptop now runs on 3GB. Good thing I didn’t go for two 2GB sticks. I read you needed to run the 64-bit version of Vista to fully harness the extra gig. So it’s effectively a 3GB maximum for me!

The eye candy that comes default with Vista Home Premium (which Home Basic does not have) is both functional and aesthetically-pleasing. I’m a fan of OS X’s Expose, and Compiz Fusion’s scale, which make switching windows easy and intuitive. Vista doesn’t have that, but instead has Flip 3D. It’s not as intuitive as Expose, since you don’t get a full view of Windows thumbnails (just the top left edges), but it does its job fine.

SpeedStep Problem on Windows Vista

My only gripe with Vista so far is that it’s not able to adequately make Intel Speedstep work! I was wondering why the laptop got hot at the bottom, and the battery lasted only one hour. The Intel T2370 processor the B1200TU ran with was supposed to have SpeedStep. That meant the processor could run at low clock speeds when it didn’t need power, and could step up the speed (and voltage) when performance processing was needed. This translated to cooler operation and power savings.

And so I installed various CPU monitoring apps like CPU-Z and RightMark CPU Clock, and they all showed that the CPU speed was hovering somewhere between 1.72 and 1.73 GHz—hardly SpeedStep-like adjustments.

So I did some research and found out that a lot of other Windows Vista users had problems with SpeedStep on Intel dual core processors. These users had no problems with SpeedStep on XP or most Linux distros on the same machines, but Vista was simply unable to control SpeedStep. It’s a pity, since Vista does have a built-in way to define the speed ranges you wanted your processor to run on.

This was a really big speedbump in my book. Having the processor cores run at full speed all the time meant fast battery draining and a hot laptop, much like using Celeron-M processors.

With much tweaking, I discovered that on the Compaq B1256TU, the Processor will SpeedStep properly after waking from sleep. So after a cold boot, SpeedStep doesn’t work. After resume from hibernation, SpeedStep doesn’t work. It will only work after the computer has been awoken from standby state.

If you have a Pentium Dual Core machine running on Windows Vista, you can verify this by using CPU-Z or RM Clock. You can monitor the processor frequency adjusting from 0.7 GHz to 1.73 GHz according to CPU load. If you want to be able to customize this (such as by under-volting, or specifying which P-states or frequencies to use), you can use the “performance on demand” setting of RMClock.

Actually, this serves as a warning to people running Vista on their laptops. I know a few people whose laptops have been overheating for no apparent reason. I’ve even read reports that the Presario B1256TU was running at abnormally high temperatures out of the box. Now I know: it’s most likely that SpeedStep is not running properly. So this means the processor is always at full speed, and depending on the load, this likely causes high temperatures.

Does anyone else have similar experiences with Vista?

As for the notebook, I’ll post a more in-depth review soon. I paid in cash, btw, so I got it for less than the published PhP 35,950 price. With Vista Home Premium included, I paid just a bit over PhP 40k.

This is for a friend of mine. He’s looking for an intelligent PHP/MySQL/JS programmer who can work full time on a telecommute/virtual office/home based position. By intelligent, I assume he meant someone who could not only code, but someone who can lay out the vision and execute plans for a particular service or web app on his own, or on coordination with others.

He should be able to do something like this:
http://vbskins.com (simple paypal IPN, JS newsletter/shopping cart,
GD-image manipulation, user registartion, etc).

Pay is very attractive at approx. $2,000 per month, depending on qualifications. That’s about 3 to 4 times the usual rate for experienced PHP programmers here in the Philippines.

They say the next logical step in the evolution of operating systems (if there ever is such a process) is bringing it online. There have been various steps taken toward this end, such as companies coming out with online versions of common Desktop tools, such as word processors, spreadsheets and notepad applications.

ajaxWindows does more, by actually offering a desktop-like interface on your Web browser, consolidating most of today’s popular Web-based apps. It even a media player one can use online!

Ron Miller says the people behind this nifty site might actually get to market their “online OS” soon.

There’s a lot to like there, but conceptually it’s mind-boggling because if you can put the whole OS on the internet, it changes the whole way we interact with and use our computers. The likes of Microsoft (and its high prices) become, dare I say, irrelevant. Of course, there is the entire matter of a business model and it’s not clear what that is. According to the About page on the ajax13 web site they are in fact a software development company, which would suggest they hope to make money from this venture. How they do that isn’t completely clear to me.

Of course in this logical progression of things (i.e., then vs. now being desktop-based vs. online-based computing), the new battlefront would be on the browser arena. Let’s not talk thin clients for now, since I think that’s too drastic.

I don’t see Internet-based OSes as being too mainstream too soon, especially given bandwidth considerations (particularly in my country), and given the marketing and lobbying power of the software giants (this means you, Microsoft). However, apps like ajaxWindows look like small steps in the right direction.

Last week I ditched Beryl in favor of Compiz Fusion. While Beryl effects are really slick, what I’m really after is the productivity boost I get with being able to manage windows and workflows more efficiently. For instance, I like how I can group windows, and how I can use different faces of the desktop cube for different window/task groups. And I particularly like the OSX Expose-like “Scale” functionality. The zoom functionality is also useful when making presentations.

However, I found Beryl to be quite unstable at times. It’s great that Compiz and the Beryl (a fork project of Compiz) had merged into Compiz Fusion. I would expect better stability and new functionalities and that’s just what I got. And they’re actually still in beta. I hear they will release a stable edition later this year.

Some screencaps. Oh, pardon the OSX-like theme. I was trying out some eye candy, and since I’m used to my Mac’s look, I guess it helps to have a more or less uniform look.

The Expose-like Scale feature

Expo is much like the Desktop Wall feature. One thing I don’t like with Desktop Wall is that it conflicts with Desktop Cube. So it’s great to have Expo along with Desktop Cube (you can move windows across the different faces easily just by dragging).

Compiz Fusion’s settings manager has less customization abilities than Beryl, though, but I guess that’s a good tradeoff if you’re after stability. And it’s still not a final/finished product (active development is ongoing). So you can still expect more. Check out a guide for installing Compiz Fusion on Ubuntu Feisty here. I hear Compiz Fusion is included by default in the next release of Ubuntu (Gutsy Gibbon).

I’ve stuck it out with Bloglines even when there were other RSS readers touted to be more cool (okay, I also used Vienna when I used my Powerbook as my main work machine). Even though the interface was a bit dull, I found beauty in the simplicity (and the lack of snazzy AJAXy effects).

Now, Bloglines has redesigned and has released its new features and interface as a beta.

Why I like it:

• Drag and drop reorganization of feeds
• Feeds are marked as read when they are actually shown in the window, not when the whole page is loaded (meaning you might have missed those posts at the bottom of the page)
• Quick switch to quick and full views
• Less page refreshes
• Seems spiffier, overall. Not like Google reader which takes forever to load.

Bloglines plasn to release this new version in full before the year ends. You can try the beta yourself by logging in to beta.bloglines.com—use your existing Bloglines login!
