Force Dynamics - Affordable Real Virtuality

Are you crazy for flight/driving simulators? Then you'll definitely want to see what I have to show you today. Force Dynamics is a company that specializes in turning virtual reality a lot more realistic. Just check their amazing 301 model in action.



Or, if you prefer F1 racing:



You can find a lot more info and videos on Force-Dynamics.

They call their 301 model a "low-cost" solution - and while I do agree that's quite affordable for professional/commercial simulators, I don't think many hardcore gamers will be ready to hand out $37,500 for it.
These models are designed for professional use - in fact, for added realism they can even offer you a more advanced model:
We also have a 401 with a base price of $52000.00 USD. The 401 has a 4th, yaw axis, which provides 180 degrees of rotation. This was designed to be used as a training simulator for professional race drivers and other high performance drivers.
I sure wouldn't mind taking one of those out for a spin. :)


But all is not lost... and for 2008 they expect to have their new Force Dynamics 201 model ready for shipment .
The 201 will be aimed at the simracer/home user. Basically it will be a scaled-down version of the 301 with more limited motion, but - more importantly - also with a much smaller price tag.

Keep your eyes and ears open, as you may very well be sitting on one less than a year from now.

I do think Force Dynamics may be tapping into an unexplored market here - lots of people invest a lot of money on "gaming". An affordable flight/driving simulator one could have in their own gaming room would surely be a huge success.

Anyone care to comment on how much you'd be willing to spend on such a system?

RIAA is getting desperate: Now suing people ripping their own CDs

Seems like 2008 won't be the year RIAA will get to see the "light".
In legal documents in its federal case against Jeffrey Howell, a Scottsdale, Ariz., man who kept a collection of about 2,000 music recordings on his personal computer, the industry maintains that it is illegal for someone who has legally purchased a CD to transfer that music into his computer.

The industry's lawyer in the case, Ira Schwartz, argues in a brief filed earlier this month that the MP3 files Howell made on his computer from legally bought CDs are "unauthorized copies" of copyrighted recordings.

"I couldn't believe it when I read that," says Ray Beckerman, a New York lawyer who represents six clients who have been sued by the RIAA. "The basic principle in the law is that you have to distribute actual physical copies to be guilty of violating copyright. But recently, the industry has been going around saying that even a personal copy on your computer is a violation."


Good... now you're alienating everyone actually buying CDs... good move... good move...
Hopefully by 2010, most artists will already be using newer and more appropriate distribution channels, and RIAA will be left defending... oh... there will be no need for RIAA anymore.

I Am Legend - Future movies and Gas prices

The good thing about movies portraying near future scenarios is that you often get a glimpse of "small" details inserted into some scenes.

In Will Smith's I Am Legend, look at what you can see on one of the scenes:



Isn't that a Batman VS Superman movie poster? Who knows, maybe they're just creating the buzz to see see how the public reacts... :)

The following frame is also quite interesting:


Have you noticed the gas prices? 6.63 USD for regular Mobil gas, ouch. That's double from now.
And considering the "world" was in that state for nearly 3 years, those prices should be from sometime next year.

Panasonic to announce a 150" Plasma

There are rumours that Panasonic is about to announce a 150" Plasma screen. This will leave the current 108" giant from Sharp miles away from it.

To get a sense of what a behemoth it will be, consider their current 103" screen:



The 150" will be over 6.5 feet high, and nearly 11.5 feet wide: meaning you'll be able to see a life-sized person on screen.

As usual, if you have to ask the price... you can't afford it.
(The 103" model costs over $52,000 in Japan)

LinuxMCE - The Perfect Media Center, and More!

If you think you can't live without Windows MCE in your living room, just have a look at what you can do with LinuxMCE.
Not only can you do all the common "media center" stuff, like watching and recording videos and TV, access it from all rooms in your house - but you can also use it to control your home lighting, phones (including voice mail,) and even alarms and surveillance cameras.

It's amazing what you can do with this LinuxMCE!

I didn't know about it, but I'll be keeping a close eye on it from now on.

LCD vs Plasma: Fight!

When you talk about LCDs and Plasmas, conversation quickly becomes a lot like opposing football teams shouting at each other.
However, no arguments can beat facts, and when you place the best LCD right next to the best Plasma TV... which one will provide a better viewing experience?

That's what the folks from Sound&Vision magazine did, comparing the LCD Samsung LN-T5281F and the Plasma Pioneer Elite PRO-110FD Kuro.
(And yes, this Samsung LCD has multi-zone led backlighting, for the best "black levels" around... or so we're told.)

And the result?

While this Samsung does indeed provide the best blacks ever seen on any LCD screen, the Pioneer Plasma can still beat it.
(oh well, there goes my bet on the LED backlighting... maybe the next version?)

In fact, these gentleman, who spend their lives looking at HD screens say that this Pioneer is the best ever screen, ever seen - period!

So, if you're still searching for the perfect Christmas gift, and have no problem spending over $4000 USD on screen, this the perfect TV for your home theater.

Samsung readying 4000x2000 LCDs?

According to NYTimes Samsung's LCDs VP said that the LCD business is going well for Samsung.

Their latest Gen 8 LCD manufacturing plant allows them to efficiently cut 50" LCD panels, unlike previous Gen 7 plants, optimized for 40" and 46" screens.

And if you think your 1080p FullHD set will last for long...

“The next wave of resolution will be 8 times the resolution of H.D.,” he predicted of high-definition sets, noting that Samsung expects to start making displays that are roughly 4000 pixels by 2000 pixels. The company hasn’t started building a plant that would do this, but it is starting to talk about the idea with potential customers.

“We’re not trying to force the market to move,” he said. “But sometimes technology surprises you and things pull in much quicker than you expect.

So, get ready - we might be enjoying full 4k movies in our living rooms before you know it.

Right Brain vs Left Brain Creativity Test


Have you ever wondered which side of your brain is more "powerful"?

Traditionally, creative people use the RIGHT side of their brains more than the LEFT.
This doesn't mean you can automatically draw or paint a masterpiece, but it sure helps you see the world in a different way.

So, just take this test and find out if you're a "righty" or a "lefty". :)

Google Analytics gets new Features

And it's time for Google Analytics to get an update.

You can now compare two graphs to easily see any correlation between them.
For instance, the AdWords traffic to average vistis, or one goal to another.
You can learn how to do it by following these instructions.




Also, the famous urchin.js has been superseded by the new ga.js wich is recommended to all new analytics tracking. Although urchin.js will continue to work, Google advises you to update to ga.js so you can use the new features of Google Analytics. For instance, with ga.js you can now track E-commerce transactions in a much more readable way.

Custom Xubuntu for Eee PC: the eeeXubuntu

It was just a matter of time until someone did it, and that time is now: Xubuntu for the Eee PC is here.

Besides providing an easier install path via USB (there's no CD/DVD drive on the Eee PC), it's also pre-configured with a desktop environment suited for its low screen resolution.

However, just like I had mentioned in my own Eee PC review:
The Ubuntu graphical installer (Ubiquity) is still too large to fit the screen in its entirety. However, holding down and dragging the installer around works fine. Unfortunately, there is no easy fix: I wish there was.
Well, I guess we can live with that to have Xubuntu running on it. :)

Tech news

WiMedia unveils strategic directions
It was promised it would change the wireless world. However, it has fallen short of its expectations. Device drivers are now fingered as the cause of disappointing data rates compared to the 480 Mbits/s PHY once touted by the Alliance. Let's see what comes out...

Integration key to 802.11n
Still in the wireless arena, the latest wireless LAN (WLAN) specification, 802.11n, poses several technical challenges. Serving multiple frequency bandwidths (2.4 GHz and/or 5 GHz) with multiple antennas, the devices used in 802.11n WLAN must be optimized for output power as well as size. In a crowded wireless world, things are getting a lot more crowded by the day.

Upgrades for PCI Express in the works
The PCI Special Interest Group is making progress on a list of feature extensions to its latest 2.0 specification. The changes are expected to enhance system performance as well as provide a smooth a path for accelerators and storage devices, all of which should be available by June 2008. Let's hope this paves the way for true SSD high-performance storage as well.

AT&T lights up 40-Gbps network
The network connects major U.S. cities and includes 18,000 miles of optical ultra-long- haul routes. Let's see if this will be a free "autobahn" or if it will be a censored version of the internet where packet filtering is the norm.

DRM was tried in 1923 - and failed!

[Original portuguese article here]

'Those who cannot remember the past are condemned to repeat it.' -- George Santayana

Well, that's exactly what's going on with DRM (Digital Rights Management) right now.
No matter how good the concept may look on paper, getting it to work without causing a major headache to consumers is a whole different matter.
You've paid for it, you'd expect to use it as you see fit.

Just not very long ago, thousands of subscribers lost all their sports games they had paid for when the company changed it's DRM scheme to a different system - they were left with nothing, unable to play those old obsolete DRM video files in their players.

The same has happened time and time again with music on portable players. Want to transfer those songs you paid for to a new portable device? You're out of luck!
In the real world, those who "pirate" stuff end up using the files as everyone should - while those who pay for it get "screwed". This doesn't make sense!

I won't even delve into wondering how they justify spending millions (billions?) in copy protection and DRM schemes - like the infamous CSS on DVDs and the AACS on newer HD discs. Schemes that are quickly bypassed by "pirates", and offer nothing good to regular consumers - quite the opposite: the added complexity drives costs up, and it's you and me who are supposed to pay for it.

Take the latest MS operating system, Vista, that devotes more time encrypting and protecting its copyrighted files from possible misuse (wasting a lot of CPU power in the process) than to make your computer work as efficiently as possible.

But let's see how things were back in 1923...


Radio gets to Austrália [1923]

(Source [BlogCampaining])

When radio broadcasts arrived to Australia, obviously they were already worried about protecting consumers from themselves - sort of an "Analog Rights Management".

So, what did they come up with? Each radio was sold tuned to a specific preset frequency. Each radio station sold it's own unique and different radio, properly sealed so that no one would dare tampering with it. (No, I'm not joking!)

Can you imagine it? Want to listen to a different radio station? Buy another radio!

Obviously, the system was deemed a complete failure in less than two years.

Today, the formats and media have changed, but they keep wanting to do just the same exact thing. You buy a song or a movie, you can only play it in a specific device, and if they ever decide you can't play it anymore - you're stuck with it.

Why is it taking so long to see this is still a failure today?

Michael Bay throws Microsoft into the HD Format Wars

As if the the back and forth arguments between the two opposing fields (HD DVD and Blu Ray) weren't enough, Hollywood star director Michael Bay has thrown Microsoft right into the middle of it. In his official forum, Bay said:
What you don't understand is corporate politics. Microsoft wants both formats to fail so they can be heroes and make the world move to digital downloads. That is the dirty secret no one is talking about. That is why Microsoft is handing out $100 million dollar checks to studios just embrace the HD DVD and not the leading, and superior Blu Ray. They want confusion in the market until they perfect the digital downloads. Time will tell and you will see the truth.

Bay
Well, I don't know if that's true or not - but it doesn't take a mega-famous director to realize that the future of High-Def movies is indeed digital downloads.

As for his preference for the Blu ray "superiority", maybe he should check what's happening with the Blu Ray profiles causing a lot of headaches for those with older players. Would you accept buying a DVD that requires you to buy a new DVD player as well? That's what's happening with bluray right now.
All the new "stuff" that Blu-ray is trying to implement, is on the HD-DVD right from the start.

Stripped from those features, HD-DVD and Bluray are basically just a storage medium, and both are enough to store a high quality MPEG4 H264 High definition movie. (Not even considering their newer mutiple layer improvements, allowing 51Gb on triple layer HD-DVDs and even more on Blu-ray discs.)

WD external HD tells you what you can(t) to with your own Files

This is nice.
You buy a brand new Western Digital 1TB external hard drive to store all your media files. You go home and trannfer all your songs and movies to the new storage device.

You head to your living room, fire up your media center and try to play a movie from your new WD disc and...
Due to unverifiable media license authentication, the most common audio and video file types cannot be shared with different users using WD Anywhere Access.
From Wired:
It doesn't matter what the files are: If you try to share these formats over a network, Western Digital assumes not just that you're a criminal, but that it is its job to police users. You see, MP3, DivX, AVI, WMV and Quicktime files are copy-protected formats.

The list of banned filetypes includes more than thirty extensions. Some of them are bizarre: .IT files are banned — these are Amiga-style music modules composed with Impulse Tracker, a particularly well-loved tracking sequencer that hasn't been updated in almost a decade. I composed with IT myself, back in the day, and still have all my shitty compositions, none of which Western Digital would have me share. (Try MOD vs. Speak&Spell masterpiece Eddie Dreams of Women, if you dare: IT, MP3)

Gmail continues to improve small details

Quietly as a mouse, Gmail continues to sneak some small improvements that - although not Earth shatering - will certainly make all our lives a little easier.

From now on you can edit your contacts name directly from the popup box that appears when you hover an email or contact name.



Simple and to the point . just how we like it! :)

Eve Online Expansion Deletes Windows XP - MS new tactic to force upgrade to Vista?


Sloppy programming? Lousy beta testing? A new way to intimidate users to upgrade to Vista?
"CCP Games recently released an expansion for their MMORPG Eve Online containing new premium graphics content. However, the installer was programmed to delete C:/boot.ini, making it impossible to reboot without manually repairing your Windows XP installation. Vista is unaffected."
It's completely unacceptable that a game expansion has such a major flaw, rendering computers useless for all but highly advanced users!

Embed Charts in Your Pages with Google Charts API

If you've ever complained about creating charts to embed in your web pages, you'll be pleased to hear about this new Google API.

Let's get straight in with an example. This URL:

http://chart.apis.google.com/chart?cht=p3&chd=s:hW&chs=250x100&chl=Hello|World

Creates this image:



That's as simple as it can get. A simple http request and you get a PNG image back with a rendered chart. Currently there are line charts, bar charts, pie charts, scatter plots, and sparklines.

Although this project began as a 20% project and was intended to be used internally - on Google Video and Google Finance - it was only natural to allow other users to use it as well.

You can find out all about it at on the Google Chart API homepage and there's a Google Chart API group for questions and support.

Google launches new iPhone Interface

With so many improvements made on Gmail on the past few days/weeks, it was only a matter of time till Google offered a gift fot iPhone users.

If you visit Google from your iPhone, you'll have a pleasant surprise: their new interface is up and running - even though it hasn't been officially announced yet.

The main Google services: search, mail, calendar, etc. are now easily accessible with fully iPhone look and style.

Its elements are quite similar to those created by Joe Hewitt, whose framework has been used in dozens of iPhone applications (such as his Facebook product.)

Other mobile devices are still redirected to the traditional Google Mobile interface.

Here are some simulated images of the new interface.
If you want real images (low quality) you can find it here.

Gmail Chat Learns to Speak AIM



After the continuous stream of Gmail improvements (like the colored labels) it's time for Gmail chat to receive a new trick: it can now talk to AIM (AOL Instant Messenger.)

Of course, you'll still need an AIM account - which you'll now be able to use in your Gmail web chat.

Next to your chat status, you'll see a new option:“Sign into AIM.”
In your Settings -> Chat dialog options you'll also find a new section called “AIM” as seen in the picture above.

How longer we'll we need to wait for MSN cross-chating? :)

Flickr offers Picnik to your Photos


Sure there are a lot of web photo editors on the Internet. But you have to admit, it's a pain dragging your photos around back and forth from your hosting site to the editing site and back again. What we really need is a way to edit our photos right where we host them... and that's exactly what Flickr is offering you now.

From now on, all you have to do to edit your photos no Flickr is to click the “edit photo” option located above one of your photos and use your imagination.

Just like other 3rd party services, you'll have to allow Picnik online photo editing services to edit and save your photos. But considering the amount of time it will save you, I'm sure no one will have a problem with that.

Eee PC Review

[Original Portuguese article here]

Now that the weekend is over and the Eee PC is back on the hands of its rightful owner (which I sincerely appreciate having lending it to me for use and abuse during the weekend) its time to write about my findings and conclusions.

To begin with, and just like I had alreade said on my first impressions post, the Asus Eee PC's size is just right. Everyone that glanced at it had that look: "I don't know what that is, but I definitely want of those!" In that department, it's a highly addictive gadget that you wish to buy right from the start.
But... is it a long lasting love? That's what I wanted to figure out...


(Eee PC size compared to a Nintendo DS and to a regular 15" laptop)

With 4Gb of flash based SSD and 512Mb of Ram, this Galaxy Black Eee PC is - in my opinion - the best looking Eee PC out there. Some may prefer the à la Mac look of the white model. But when you notice those black speakers standing out next to its tiny 7" LCD screen... you'd wish you had this all black model - it looks a lot better


(Eee PC compared to a wireless mini-keyboard; guess that mini is not mini enough)

Such a tiny keyboard requires some getting used to, but I found its layout quite pleasing. The "Fn" key is not obnoxiously required as in some other UMPCs, and its allows you to type reasonably well (even with my big hands) once you get used not to move your fingers around so much as usual.



The Trackpad is tiny but surprisingly usable. It also implements the "scroll" function - which is a real requirement with such a tiny screen (800x480) however I found it a big disapointment when it came to a simple feature: the "tap" that does a left mouse button click. If you're used to using the physical mouse buttons next to the trackpad, you won't have a problem - but I use "tapping" a lot, and nearly half of the time, those taps were not properly detected.
I messed around with the trackpad settings, trying every possible combination, but I never got it to work right.
It's a bit odd, as even the lowest-end PCs have quite usable "tappable" trackpads...
It remains to be seen if this was a faulty trackpad, or if it's a driver issue that could be improved by a future update.

The 7" LCD is reasonable. I was hoping to try it out outdoors on a sunny day - but I can't control the weather and just got dark overcast skies. So, I can't say if it will be usable under direct sunlight (most likely it won't.)
However, my main gripe with the Eee PC is indeed related to the LCD - it's "low" resolution.
A few years back maybe we could live with a 800x480 screen resolution... today we can't.



I mean... sure, this is enough when you're using the Eee PC in its "easy mode", with its large icons and tab selections. However, not every program 3rd party is designed to work at those resolutions.
Although it may be enough to work on Open Office, typing some letter and using its spreadsheets; when you launch firefox to navigate the web, things get a bit more cramped.
In its regular view you'll end up seeing just the ad banners on top of websites. Even if you use the "full-screen" view (highly recommended) it will still feel claustrophobic when using Google Maps, Gmail, and Google Reader. It could really use some extra vertical resolution.

But it's not just about the internet - even when trying to access some configuration screens on several programs, it's not that hard to find a dialog window that doesn't entirely fit the screen. You'll end up with several inaccessible options, as well as "OK, CANCEL" buttons placed outside your view area.
You'll need to press ALT+ left mouse click + move your mouse to drag the window around and use it; hardly intuitive for a newcomer.

On some other devices using this same resolution, like Nokia's MIDs N770, N800, N810 - they have a couple things in its favor. They have a touchscreen for easier interaction, and most of their software is designed with that resolution in mind. Today's Linux and Windows Operating systems are designed to be used in far higher resolutions. Some programs even fail to launch at such low resolution.
Having a virtual higher resolution could also help a bit, having a 1024 or 1200 screen resolution rescaled to show on screen.

However, the best solution would be to have a proper screen with slightly bigger dimensions (8" or 9") with a higer 1024x600 or 1280x800 resolution.
However, it's easy to understand why Asus used this screen: it certainly is a lot cheaper!
This type of screens is used in a lot of devices, and it certainly helped keep its target price.
Furthermore, for its target audience this screen may be "enough" - though I'm sure it will be the reason that will keep a lot of more advanced users away from the Eee.


(Eee PC with a bigger screen - ok, maybe 50" is a bit overkill :)

When you press the "on/off" button, the Eee PC takes just a bit over 15 seconds to be completely loaded and ready to work. Some PC motherboard need more time just to pass the BIOS tests and RAID configurations!
Its performance is more than adequate for Open Office and internet browsing. Obviously, by lacking a swap file and only 512Mb of RAM, you won't be able to keep many programs open at the same time. Leaving a couple open office documents open and browsing the web can quickly lead to some "out-of memory" errors. The 1Gb model will be more adequate for intensive use.
You might also want to consider upgrading to 2Gb RAM. But keep in mind that you need to recompile the kernel in order to get 2Gb in Xandros. If you plan to use Windows XP the full 2Gb will be instantly recognized, though you might want to read my post regarding XP and SSD)

After the first round of boots and reboots, suspends and resumes, and checking the pre-installed applications (which I won't delve into as many other sites have already talked about it,) I activated the "advanced mode" that allows you to boot into the traditional linux environment (Xandros.)
Well, a lot of people will want to use this mode. You can now have full access to your machine, and install new applications through synaptic.
As a curiosity, there is a small voice "recognition" application that allows you to launch programs by speaking "Computer Web, Computer Calculator, etc." - but if you're in a noisy environment, forget it.


(Remote Desktop from the Eee PC)

I even dared trying Google Earth, just to see how it worked - but it didn't work too good. It was s l o w... very slow. More than a couple of seconds per frame. I don't think this has to do with the 900Mhz Eee PC CPU alone. Maybe it's a driver issue, or the lack of memory or swap file. I'm sure it can get better when a new updated version comes out.



WiFi reception is great. I was able to use the Eee PC in places my Acer laptop was unable to. However, if you suspend it and resume it, your WiFi connection will require a manual reconnect to work again. I'm not a linux guru, but I read there are already some scripts to fix this - but this should have been better handled right out of the box.

Connecting a digital camera and iPod to its USB ports is not a problem, though you may want to replace those programs and install your personal favorites for that.
When trying some USB pen drives, two of them were recognized but failed to show up on the file explorer. A old 128Mb and a newer 2Gb sticks weren't displayed. That was odd, as both work fine in both my windows and ubuntu computers.

If I had more time, I would have tried installing Ubuntu and XP on the Eee PC to see how it handled. But I prefer to leave those tests to its bigger brother with 8Gb flash and 1Gb Ram (preferably expanded to 2Gb.)

Like it was said, if you want to upgrade its memory, you'll need to remover a "warranty void" sticker:



In the USA this is illegal, as the buyer has the right to upgrade the computers s/he owns.

As a conclusion: the Asus Eee PC is a nice "toy" which you wish to have. For its price there are no other devices like it.
Its the perfect computer for children, and for everyone requiring a light ultra-portable laptop to carry around for occasional web browsing and open office work.
For advanced users waiting for the perfect UMPC, this may be close, but the limited screen resolution and lack of mobile connectivity options such as bluetooth (though you can add it yourself if you0re brave enough) might keep you waiting for its next version.

Will I buy one?... I haven't made up my mind yet.

For me, the SSD space is not the issue (there will even be a Elite Eee PC with 16Gb SSD flash for a few select developers) - it's all about the LCD resolution.
I'd want to use it as a always connected UMPC wherever I'd go. Bluetooth or HSPDA would be essential. And for remote access work, anything less than 1024x768 just isn't enough.
(But these are my personal requirements for the use I'd like to use it for)

For those wanting a small and simple computer to do some office work, probably a 2nd or even 3rd computer to have around, this low cost tiny laptop is a highly attractive option you should consider seriously.

Pros:
  • Price
  • Small, lightweight
  • Easy mode interface for first time users
  • Flash SSD storage
Cons:
  • Low resolution LCD might feel "cramped"
  • Trackpad "tap" doesn't always work
  • 512Mb RAM may cause "out-of-memory" errors
For many, this will be a nice Christmas gift, for me... I guess I'll keep waiting for a Fujitsu U810/U1010 form factor with a P1610 screen... at the Eee PC's price! :)

Optimizing Windows XP for SSD use

[Original portuguese article here]



Although SSD (Solid State Disks) are now becoming a lot more common (even cheap mini-laptops like the Eee PC use Flash disk storage) it doesn't mean that our old trusted MS Windows XP knows how to use it properly.



The main issue with flash based SSD is the limited number of write cycles.

Although hundreds of thousands may sound like a lot, a computer can issue hundreds of writes per second - and even though some SSD use a "smart" relocation scheme, so it spreads the writes across different sectors in order not to wear down a single area; the fact remains that paging files and temporary files cause significant degradation that can cause disk errors in just a few months of regular use.



On Linux (like on the Asus Eee PC) you can turn off the swap files with just 512Mb of Ram; on Windows XP that wouldn't be possible (and would be even worse on Vista.)



So, before considering upgrading your laptop or UMPC for SSD use, it's best to upgrade your RAM to its highest capacity.

On XP, with 2Gb of Ram you can turn off the paging file - I've done so over 2 years ago and just rarely get a "out of memory" error (and only when forcing it, like trying to use Photoshop to edit multiple 12Mpixels images while having 2 browsers with dozens of tabs open, and burning a DVD at the same time.) Under regular conditions, even with multiple browsers open, I can still play memory intensive games like ETQW and UT3 without any problem.



With no swap file, you avoid the constant disk trashing due to the page file constant reading/writing, However, there's still more to be done.



There are other programs that use disk space for temporary buffers and caches. Internet Browsers are probably the worst of them. Each time you visit a new page, hundreds of small files are written to disc to speed up future requests. Although not a big deal on magnetic hard drives, these are not well suited to SSD.

Until these programs offer a finer control on how to use their RAM/disk caches and memory usage, the most efficient way to deal with it is by using a RAM disk.

Yes, I know it sound illogical - waste RAM making it look like it's a disc... However it does work out ok for the time being.

You just need to configure your programs to use the newly created ram disk to store their temporary files.

(As an added advantage you also stop worrying about cleaning your disk and privacy issues - every time you reboot it will clear all you temporary files; though some Ram disk drivers also allow you to commit the changes to disk at shutdown time, restoring it when you boot up again.)



There still one other alternative - though it requires a fair amount of computer knowledge.

If you use the EWF (Enhanced Write Filter) originally designed for XP Embedded, it allows you to manage writes much more efficiently.

Just like Ubuntu "live CD" that allows you to boot and save files even if you don't have a hard-drive installed, the EWF reroutes all writes through a management layer which would allow you to commit the changes to disk only when absolutely necessary. Usually, when a shutdown/suspend is in order, or when some extra free memory was required. However, this is not easy to setup, and not indicated for a "normal" windows user.



With Linux - although I'm not an expert on it - I imagine all these changes would be a lot easier to implement (or they might be there already, requiring just the correct settings.)



On Windows, as we can't change its source-code, we need to resort to these ips and tricks to maximize SSD performance and reliability (though you can also use it even if you use regular Hard-Drives.

  • Install as much RAM as possible (at least 2Gb, but ideally 3 or 4Gb)

  • Deactivate the paging file

  • Use 128-512Mb as a RAM disk (depending on your needs) and setup your programs to use it as storage space for temporary files/caches
