However, there are some areas that Borland didn’t cover (non insulated code). One of them is Internet-oriented applications. For this kind of applications the Delphi coder has to rely on MS libraries. Well, there is the possibility to rely on complex 3rd party Delphi libraries but this is not better that relying of MS libraries. Maybe worse. We all know how many 3rd party libraries died or were left to be eaten by time and rust.
I have seen that some people (especially those that are not from Europe or other countries that have lawsuit against MS) imagine that any computer in the world has to have MS Office and Internet Explorer installed by default! Well people, it is not like that. You cannot just believe (religion has no place in programming) or even hope that the client has the latest Win 7 64 bit OS, service pack, IE, IE updates, XML libraries, dot NET, Java, etc, etc, etc, etc, installed in its machine. You need to start from the premise that they have none of them installed. Only then your application may be robust and working on all Win OS platforms.
So, depending on MS libraries is obviously pure evil for a Delphi programmer (and not only). But we still need to connect to Internet and do fancy stuff such as downloading files (well, for Delphi this is indeed fancy!) while keeping the application system-independent and robust. So, we have to choose between using a 3rd party library which will probably get obsolete and unmaintained sooner than later or to use MS libraries. The thing with using Delphi code to connect to internet based on MS libraries is that the code seems unreliable. It is not multithreaded and it lacks the support for detecting connectivity problems. The application may freeze to death if the, physical connection breaks, if the modem dies, if the ISP is down, if the web server is not responding, etc.
So, let’s see the advantages as disadvantages:
3rd Delphi party libraries:
* They may die and get obsolete.
* Large libraries (such as Indy) will increase the compilation time with several good seconds!
* Are difficult to maintain
* May have poor support (if any at all)
* Many of them that anti-freezing support
Code based on MS libraries (such as IE)
* May not work in all computers (especially in Europe)
* Have no anti-freezing support
* Difficult to use (no support also)
I actually don't know what it worst: application freezing (for a long while) while trying to connect to Internet or application not downloading the file until you convince the user to manually install stuff (MS internet related libraries) in its computer. Basically if you convince the user to go to MS web site and install stuff, then you will rather send it directly to your web site and manually download the stuff your program needs :) :) :) :) :)
Some may instantly fall into the sin of thinking that the “solution” is to deliver the libraries with the application, and install them when the application starts. Well, do you really mess up with user’s system? They are so possessive about their computers. As soon as they will see you installed stuff into their system core they will immediately start posting of forum how evil your application is and how you have tried to take over their system.

Best charger ever
What you will NOT find here:
NiCd batteries are now considered obsolete so we will not review this chemistry.
Chargers that are work at 110V (USA) will also be ignored. Portability is an important factor, as you may want to take your charger with you when you travel with your digital camera.
Weak chargers (under 2100mAh) has been ignored also. This place is not for lamers :)
What you should expect from a charger:
Powerful, portable and most of all, smart! Smart means it that it measures the voltage and temperature of the battery during charging process. This way it knows when to stop the charging, protecting your batteries.

You know a better charger? Please let us know (email us).
Channels - the charger can load the batteries two by two (not so great) or independently (this way you can load three batteries at once, for example, instead of two or four)
General score - Score given by other people/reviewers. On a scale from 1 to 10.
Advices for storing batteries:
Store between 40 and 80 degrees F. Do not refrigerate.
Batteries will self-discharge if left unused.
NiMh batteries should be stored fully charged and recharged every 30 days to keep in peak capacity.
NiCd batteries should be stored fully discharged.
Do not “store” batteries in the charger.
It is not recommended to “condition” batteries until after they have bee charged and used 10 times.

After purchasing the Toshiba Qosmio laptop, I have seen that only 450GB of 500 are available. Few hours after purchase I discovered that two large hidden partitions were created by Toshiba. One is 1GB large and it seems to be the standard Windows 7 hidden partition - but obviously much larger. The second one is not less than 10.3GB in size! It seems to contain the recovery software (Windows setup, drivers, etc.)
The second partition is safe to delete since the so called "recovery" tool offered by Toshiba is 100% useless because it will format your drive and reinstall Windows instead of actually trying to recover the data for you.
So, no matter what you do, DO NOT use Toshiba's recovery utility if you have and important files on your drive!
The partitions can bee seen using the Disk Management utility.
Start>Control Panel>Administrative Tools>Computer Managment>Disk Management
Just delete the last partition (not also the first one!) and expand the previous one to fill the free space.

To reach the automatic recovery utility and use it to repair the bot automatically, you have two options:
A. 1) If your computer is NOT booting at all:
Insert Windows 7 installation CD and re-start your system. Press any key when you are prompted to. In the windows that will start, choose your favourite input language/keyboard. Click 'Next'. Choose 'Repair' option. Then use the onscreen wizard (first menu is what you are looking for) to let Windows repair your boot automatically.
A. 2) If your computer is booting (but Windows in not loading), you don't need to boot from a CD. Just restart your computer and keep the F8 key pressed. A special menu will appear. Choose the last item called "system recovery" and do the same as above.
If automatic recovery is not working, go to plan B.
B) Manual recovery.
These MS utilities may be if great help to you:
You will not find these utilities in Windows. These utilities are available only in the System Recovery utility (folow steps A1 or A2 to reach the System Recovery utility).
Start a DOS console (click 'Command Prompt' in the 'System Recovery Options' dialog box) and type:
After this you can list the available operation systems/disks:
The /ScanOs option scans all disks for installations that are compatible with Windows Vista. Additionally, this option displays the entries that are currently not in the BCD store. Use this option when there are Windows Vista installations that the Boot Manager menu does not list.
Finally type the last command; the most important one:
This command scans all disks for installations that are compatible with Windows Vista. Additionally, this option lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD.
If it is not working, you can try to force the boot installation manually:
Bootsect.exe c: /NT60
Use the correct drive letter instead of C:.
Use /nt52 instead of /nt60 if the operation system on the disk is below Windows Vista
Use the "BootSect.exe /NT60 ALL" command to restore the boot sector on all drives.
Prevent the disaster
The boot information if kept in a file called "c:\boot\bcd". If your computer is working fine now, stop any reading you are doing now, and go immediately and make a copy of this file. You can name it "bcd.good" If later you will thank me for this. If you are playing with the above commands and ruin your boot, you can restore it by renaming the "bcd.good" file back to "bcd". Note: the c:\boot folder may be hidden (invisible).

Easy BCD - freeware
EasyBCD is NeoSmart Technologies' multiple award-winning answer to tweaking the new Windows Vista bootloader. With EasyBCD, almost anything is possible. Setting up and configuring Windows boot entries is simple, and there is no easier way to quickly boot right into Linux, Mac OS X, or BSD straight from the Windows Vista bootloader - on the fly, no expert knowledge needed!
x505 is a very powerful gaming (ish) oriented laptop from Toshiba. Actually, it is pretty powerful (of course a laptop can never be a desktop replacement) for the amount of money you spend on it.
First of all I was impressed by the amount of bloatware and crapware Toshiba installed in this computer. The size of the hard drive is 500GB. After formatting only 477GB are available for use (this is normal). From this amount, Toshiba wasted about 27GB for crapware (well, I guess 1 or 2 GB goes to Windows OS). So, only 453GB were available.
When starting Windows, then amount of RAM wasted to run all Toshiba bloatware is 1.4GB and the boot time is OVER TWO MINUTES. Amazing, huh?
Edit: Just installed Windows XP 32 bit and the boot time is about 40 seconds. Toshiba offer no support for Windows XP or any other 32 bit OS, so you are on your own if you REALLY want to do it!
See my post in July. It will give you some guidance in this big adventure. It took me more than 16 hours to do it.
Toshiba Qosmio x505, red/black
CPU: Intel Core i5 M430 2.27GHz
Graphics: GForce nVidia GTS360M
(see details at the end of this post)
OS: Win 7 Home Premium, 64 Bit
Price: $1099 + $47 shipping
Purchased from: J&R www.JR.com, USA (They really suck. I paid $47 for overnight shipping but they delayed the shipment few days).
Windows Experience Index (Win7 64 bit - June 2010)
Windows Experience Index (Win7 32 bit - February 2011)
I know, compared with my ancient desktop computer, the performance of this laptop really sucks.
Included goodies*: none
Included software (not counting free crapware like Acrobat Reader): Microsoft Works
*I was expected to find some goodies in the package, such as USB adapters, VGA/HDMI adapters, screen cleaning cloth, car 12V power adapter, etc, etc, etc. There was nothing in the package (except the gigantic brick-like charger). Nothing. Not even the Windows 7 CD. I never receive such a disappointing empty package for an expensive product in my life.
Performance index: Windows 7 gives a shameful 5.9 to this Toshiba laptop.
For $1200, an index of 5.9 is not something to be proud of. With this kind of money you can upgrade your PC to a mega number-crunching monster.
Dead pixels: none
I was lucky here :)
Screen quality (1-10 scale): 6 (update: I just downgraded this to 5).
Screen quality is good.
Update: I just found that I can adjust screen brightness and contrast from nVidia software. The image quality is much better. Unfortunately, the controls are not easy accessible (more than 3 clicks away). If the light level changes often in your room, it will be difficult to re-adjust your screen contrast.
TouchPad quality (1-10 scale):
The touch pad has a rough texture. This makes your finger not to smoothly glide over it so the cursor movement is extremely jerky especially if the fingers gets sweaty.
Update1: the more I use the touch pad the more I hate it. I will go today to purchase a true touch pad tablet.
Update2: I just upgraded this from 2 to 3 after uninstalling touch pad drivers. Now it works way much better).
Quick multimedia buttons:
Some buttons have a very bad placement, so when you rest your arms or use the keyboard you accidentally touch them. Most annoying is when you want to press the Escape key and accidentally touch the "start player" button. This will start the dreadful MediaPlayer when you DON'T need it.
Sound quality (1-10 scale):
Update: The choppy sound improved significantly after uninstalling crappy sound utilities (not sound drivers) such as Dolby Surround tool. Grade upgraded for 6 points to 8.
Keyboard quality (1-10 scale): 7
Keyboard itself is not bad. On the other side, its layout is not great.
Keys layout (1-10 scale): 4
Web camera quality: average
Compared with the web camera I have on my EEE PC 1000, the quality of this web camera is really poor. The edges of objects appear extremely sharp (like in a game with no anti-aliasing) and the image is extremely dark if the room is not enough illuminated (you need to stay in direct sunlight to obtain a good picture).
Adjectives like slim, small, tiny, thin, etc cannot be used when one is describing this computer. The laptop is gigantic and mega heavy. However, I will not give a small grade to Toshiba Qosmio because it is big. I wanted a powerful and big screen laptop so I expected something big (even though it could have been better).
Battery and Power adapter:
Yes. This laptop needs a special section for 'power adapter'. The power adapter is more than "huge". I will rather use adjectives such "gigantic", "humongous", "enormous" and "brick size" for weight and size.
Here are some reviews right on Toshiba's web site. 99% of customers agree that the charger is huge: http://www.toshibadirect.com/td/b2c/adet.to?poid=366631
Battery will discharge to 1% in about 3 hours. Not very bad, but also remember the battery is youg, it will get old really quickly especially that Toshiba exaggerated with the loading time - about two hours to fully charge the battery!! This will kill the battery really soon!
Test conditions: Initially the battery was fully charged. I was installing drivers for Win XP, browsing the Internet, rebooting 4 times. The screen brightness was set to 6 (out of 8).
Very very nice design. The red back-lights make a nice impression over the black background, especially in dark.
Boot speed: 3
Boot speed time after some bloatware was remove from start up is about 105 seconds. We can see that the low performance HDD drive put its fingerprint over computer's overall speed.
The TouchPad has a handy button from where you can quickly turn it on/off.
Nice, design. Nice backlight for all non-keyboard buttons.
Pretty quiet when working at low capacity (extremely loud for 4-5 seconds after power on).
Nice HDD anti-shock (and anti-drop) protection.
eSATA port (I really needed that for my external drive).
Button to turn on/off the wireless LAN.
Adware, crapware, bloatware
The worst thing about this laptop (except the power adapter size and no support for XP) is the software. So, the first thing to do first after purchasing the laptop was to start uninstalling the crapware and adware.
Adobe Acrobat reader: 209MB
Toshiba Online Backup (you have to pay to use it): 2.2MB
Amazon Links (more crappy stuff that you need to pay for): MB
Google Toolbar for IE: KB
Norton Internet Security (demo): about 200MB
Microsoft Office Student 60 Days demo: about 350MB
Jerky sound utility (makes Winamp lover the volume every time the OS makes a system sound.
NetZero adware ("free" software that connects you to a service for which you have to pay)
Some blog/hosting services adware ("free" software that connects you to a service for which you have to pay)
WildTangent adware ("free" gaming platform that connects you to a service for which you have to pay)
TouchPad driver (interfere with my tablet driver; the touchpad acted weird anyway before isntalling the tablet)
Many other garbage Toshiba utilities removed...
Big and powerful.
Very good gaming performance (for a laptop).
Good battery file (for this power consumption).
It doesn't get too hot.
Tons crappy software (bloatware) preinstalled.
Really bad drivers.
Poor sound card.
It came with Windows 64 bits. No software and drivers for Windows XP.
Poor customer support (no email support at all). No printed manual. No Windows CD (or at least recovery CD).
Gigantic power adapter.
Really heavy (well it is somehow expected to be that heavy).

I couldn't believe my eye when I open the package and found inside a charger that was almost the size of a brick. To give more accurate measurements, the power adapter is exactly 3 times smaller than my old EEE PC 1000 and about the same weight!
Some pictures will come soon, so if you don't believe me I will show you.
Toshiba Qosmio - Hands on
Thursday, June 3, 2010
Today everybody is blogging, everybody can put a cheap answer on a free “social network” web site and everybody can “spit” information. But rarely the experts are speaking. Usually, there are just 15 years old kids expressing random opinion from their “experienced” life. The worst of all is Yahoo Answers where the (kitsch) avatars of the people worth more than the “information” they over-enthusiastic share.
I had a good laugh today when reading a section about hard drive failures on WikiAnswers web site. Somebody was asking how to repair a dead disk. The answer? "Although in some cases the error can be fixed by adding cooling or defragging and/or formatting…" (WikiAnserws, 2008).
Follow non-expert opinions and all you will get is a dead drive and a bunch of lost data.
This is the difference between a paid answer and a wiki answer: instead of replacing the disk for a lazy $100 you are going to spend $5000 in a Data Recovery shop.
I don't know from where the people got the idea that defrag/format if a magic tool that repair all computer's problem. Is like an urban myth. I use format just once at 2-3 years when I buy a new hard drive.
In this case adding extra cooling is like hiding the pain provoked by a serious disease with painkillers, defrag is like treating cancer with aspirin and formatting is like a criminal deciding to start a new life by making some quick money :)
A pro will never waste its time to provide free answers for newbie on such wikies (especially when it can sell its answer for a good price on other channels).
I don't think that WikiAnwers has a chance of success on long run. When you base your business on cheap content provided by random users all you can offer is answer of low quality.
The problem today is that Internet is over-saturated by these phenomena. Blogs and forums and wikies appeared all over in the last few years, all pretending that their community is better than others. I don't say that these things should not exist. Everybody has the right to express its opinion. What I am saying is that after a bloom always follows a burst (like in the case of dot net burst in 2000-2001). Soon all these free sources of (inexact) content fill filter out by themselves.
At the end all you can ask your self is how to call it: 'free content' or 'cheap information’?
PS: also ready the “User generated content: No Guarantee of Validity" declaration on WikiAnserws web site (at http://www.answers.com/main/disclaimer.jsp). It speaks by itself.
WikiAnserws (2008) What does SMART failure mean [Online] Available from: http://wiki.answers.com/Q/What_does_SMART_failure_mean
(Accessed: 16 April 2008)
- Avoid low priced offers
Never go for a hosting company that offers you too much bandwidth and space for a small amount of money. Some hosts may even offer you infinite space or bandwidth. They will bitterly disappoint you. Reason? The hardware of a server is limited. You can't offer infinite hard drive space. Not even for a huge amount of money.
Additionally to this point, I will add a new advice: don't purchase hosting for a full year. Buy only one or two months. If something goes wrong, you just move your site to another company without loosing the payment of the full year. Companies promising you huge discounts if you buy a full year (or even two), are trying to get you into their trap. If the first two months are ok, then you can go for a 6 months plan and that for a full year.
- Make sure that there are absolutely no hidden charges.
If you purchased hosting and you find out along the way that there is a hidden fee, than you should prepare yourself for a bumpy road with this company. Host a backup of your web site on a free hosting server. In case your original host creates you problems you can switch to the backup until you move the whole website to a better place. Hidden fees are a 100% indicator that something is wrong - and it is true not in the web hosting world but in every commerce and e-commerce business.
- Hosts charging 'one time setup' fees MAY indicate a possible problem.
The setup of a new account is made automatically b the server's software. So, a setup fee can mean only 2 things: a) the companies tries to get some extra money from you (not so bad) or b) the company is trying to 'trap' you - many people are going to stay with a mediocre-to-bad hosting company because they already paid once the 'setup' fee and they don't want to pay it again if they move to a new company (this is more bad than point a)).
- Support - the worst thing that my happen to you is poor support. Every time something needs to be changed to your server or every time your site has problems, you will contact the support team. If they don't have a 24 of 24 hours per day support (ja-ja… they all pretend to have 24/24 support but it isn't always true), then you will have to wait until the support team came to the job and drink their morning coffee. It is easy to check this: make three phone calls at different hours (morning, day, night) and see who will answer: a machine or a person. Also send emails using different email addresses and see if you get answers in less than 2-3 hours (you can ask silly questions about their services and servers).
- Check the Internet and see the ratio of positive/negative feedback/comments. You will never find a 100% positive feedback for a company but it will be easy to see who the winner of 'negative feedback award' is.
Another few advices at the end:
- Inquiry if the host is flexible. Some hosts allow you to choose a customized package that will suit your needs in the best way. However this comes with a nice price attached. Ask for it only if you are running a big site that needs specials customizations. In this case it may be more suited for you to rent a full server and to do whatever you want with it (though you will need some Linux knowledge).
- Location: if your customers are from Europe, don't host your site in America - and vice-versa.
- Go for Linux instead of Windows. Linux never was a good OS for desktop users. However it is magic when we are speaking about servers; also it is fully customizable and very stable.
- Always choose well know and all-over-used technologies (even if they are obsolete) instead of new/unknown ones. For example you will have a much greater community for PHP than ASP. It will be easier to move you site to a different host is you choose MySQL over MSSQL …

I see that for folders created under Win XP I have some user groups that do not exist for 'normal' folders (folders created by me recently under Windows 7).
For example, for the Win XP folder I have:
* Creator owner
* Account unknown(S-1-5-21 blablabla...
For Win7 folders I have:
* Authenticated users
Trying to delete the 'Account unknown' gives me:
Windows Security You can't remove Account Unknown(S-1-5-21-1220945662-706699826-839522115-1003) because this object is inheriting permissions from its parent. To remove Account Unknown(S-1-5-21-1220945662-706699826-839522115-1003), you must prevent this object from inheriting permissions. Turn off the option for inheriting permissions, and then try removing Account Unknown(S-1-5-21-1220945662-706699826-839522115-1003) again.
Now you will be able to access the XP folders like any other regular Win 7 folder.
I have found that some junk is left behind if you are using the first solution. More exactly you will see an account called 'Unknown user' appended to all yuour old folders. The best solution is to rename the current folder for example from 'MyData' to 'Old', make a new folder using the original name ('MyData') and move all content from the old folder ('Old') to the new folder ('MyData'). The new MyData folder will have the correct permissions applied to it.
Anyway, some stuff are still difficult to use it, for example, you have to click a lot to change a simple setting such as "Hibernate after x hours".
Managing file association is the biggest mess. My (advanced) file manager has a nice and handy tool that lets you to change file type associations in just 3 seconds. However, Windows 7 does not like you to do this from any other point expect its own bulky and difficult to use interface.
Under Windows XP, while performing regular tasks (programming, music, browsing), the CPU utilization was 0%. In Win 7 the CPU is usually at 30% even more. So, 30% of your CPU will be wasted for doing nothing (well, not quite nothing, probably for displaying the eye-candy Windows interface). If you look in Task Manager, non application is taking CPU, so probably those 30% of CPU utilization goes to the kernel/GUI.
Under XP I used to defrag my disk while I was working. Under Windows 7, the computer cannot be used when you defrag your disk. Even if my disk has a nice Experience Rating of 7, while defragging, the whole computer runs like a slug.
When speaking about reliability and stability, it seems Windows 7 needs several SP releases until it gets to the point where Windows XP is. Installed from the CD, it seems to be unstable. However, I let Windows 7 to upgrade itself and I got no additional blue screens until now. Let's hope it will stay this way.
Switching to a new OS without waiting for the service packs to be released may a hasty act. But it is also nice the breath of fresh air that Win 7 offers. Think only to those poor guys that upgrade to Vista in its early days. They were used a Guinea pigs.
I will recommend you NOT to switch YET to Windows 7 definitively, but to install it as secondary OS, especially if your hardware is more than 9 months old! Then migrate slowly your non-critical software (multimedia players and so) and leave the productivity tool on the XP machine. When you think Windows 7 is stable and fast enough (after you have upgraded your hardware) you can move to Win 7 definitively.
