Application developed under Delphi 7 are 32 bit, and they can only access a limited amount of RAM. This Microsoft document says that the limit is 2GB. So I have made some tests and indeed I could not allocate more than 2GB of RAM. However, The document also says that 32bit applications could access up
What they charge? Are you new to online software selling? How much do you think you will make when you sell a copy of your software that worth $100? $99? Wrong! $95? Wrong! $90? Wrong! $80? Wrong! $50? Wrong! $40? Still wrong! Let’s take example of a $100 order placed via PO by your customer.
This is doable. In your user profile folder find the prefs.js file. In this file change the order of your accounts like this: user_pref(“mail.microsoft.accounts”, “account4,account1,account3,account2”); You can also use a Firefox extension called ‘Folderpane Tools’. Once you successfully installed the extension you will be able to define the new sorting orde. To configure Folderpane Tools:
I had problems in the last month with Firefox which refused to remember the URLs I typed in the address bar. There is a fuzzy Mozilla article that says to fix bookmarks problems. However it applies also to the problem described above. The article says that deleting the ‘places.sqlite’ will solve the problem but you

More horror stories about Toshiba’s crappy drivers. I just find out that turning on the year-candy features in Toshiba (x505) sound driver (especially the Dolby stuff) will eat one on my CPU’s cores! The high CPU utilization cannot be viewed directly from Task Manager since it is generated by a driver. Instead can be seen

The application priority was set to High in Task Manager. ————- Start point: No optimization: 2.28 sec ————- Test 1: With FastMM4 enabled: 2.23 sec With FastMM4 enabled and RtlVclOptimize: 2.18 sec With FastMM4 enabled and VCLFixPack: 2.10 sec With FastMM4 enabled and FastCode: 2.09 sec All (FastMM4 and RtlVclOptimize
Recently I wanted to test some things and I wanted to comment some of the units used in my project, in the DRP file. Unfortunately, I forgot to close the comment (close bracket}) so I commented too much code in that DPR. As soon as I compiled the project I got an access violation in

Today I recompiled and run a program. FastMM started to report all kind of strange memory leaks but it was unable to locate the source of the error (unknown address). After a while I tried disabling FastMM and recompiling the program. The program was recompiled but it had no icon. Solution: After a long trial

It looks it is possible to switch from IDE to AHCI after Windows was installed in IDE mode.

1. Note: If you already have an empty partition to install XP on it, use it and jump to step 2. Shrink the existing partition (use Computer Management-> Disk Management) to make room for the second partition. For Windows XP you need minimum 4GB. In the space that you just freed, create the new partition.

When did you looked last time in your ‘Plugins’ section of your Firefox browser? Did you know that you have lots of garbage there?

Few months ago I had to run a test to see if DNA sequence files (FASTA files) compress better than simple text files. DNA files contains only 4 characters (A, C, G, T) so you will expect that they will compress really well compared with text files. However, the DNA code is pretty random (well

Some raw notes about distributed databases. If you want to start with parallel databases then you need some good knowledge about traditional (non-distributed) data bases.

Raw Notes on Parallel Programming Parallel programming involves multiple tasks running simultaneously to process data or execute instructions. I’ve been exploring parallel computing for a recent project, and I’ve come across various definitions and distinctions in the literature. These terms often have loose interpretations, so it’s worth noting that each book or source defines them
Distributed Processing: Raw Resources (2008/2009) I’ve decided to share some of my 2008/2009 notes on distributed processing. These documents are just raw material and personal observations from my research at the time. While I intend to revisit and organize them into a more presentable format, here’s the first post in a series of about 30
Web applications are increasingly popular, but are they truly “real” applications? Given the limitations of web technology, it’s clear that web “applications” can’t match the functionality of traditional desktop applications. This is why 96.4% of users still prefer desktop software (like Word) over basic online tools (such as Google Docs). An interesting observation about the

Here is a “nasty” article about how to hack your Windows 7 32 bit to use more than 4GB or RAM. It looks like MS Windows can use more than 4GB or RAM but MS don’t want to sell it that way: “That 32-bit editions of Windows Vista are limited to 4GB is not because
I strongly recommend against Windows XP on 64 bits. It has NO advantage over Win XP 32 bit unless you have more than 3.2GB of RAM.If you have 4GB of RAM, Win XP 64 bits will give you back those 0.8GB of RAM that Win XP 32 bit cannot access, but at the same time
There’s nothing worse than a Delphi programmer writing code like a Visual C++ programmer. Delphi developers have the distinct advantage of creating applications that are isolated within the Windows OS. This is why applications compiled for Windows 3.1 are still running on Windows 7. However, Borland didn’t cover every area—especially when it comes to non-isolated
