Excel 2007 has a bug with the display of floating-point values, a Microsoft developer confirmed on his team's blog yesterday. BetaNews confirmed the bug's existence, which leads to some values in floating-point multiplication to be "rounded" to incorrect values.

Jikes is a great compiler but they could really benefit from better project management.  This bug  has been open for greater than 3 years now with no resolution.  One of the developers sent me a *private* email (without commenting or closing the bug) this this could be fixed by avoiding the use of symlinks but wasn't sure. Of course this email was sent more than 2 years ago so I have no decent way of finding it.  Adding insult to injury is the fact that IBM won't let me comment on the bug without an account.  The only problem is that my account won't activate.  In a nutshell if you want to use incremental compile with jikes you need to specify relative paths not full paths.  For example if y ...

Evolt.org has an interesting new article posted today about combining CSS and PHP to display fractions correctly on your pages.   Most of us are uncomfortable with using fractions when writing programs. If we encounter a fraction, we will first convert it into a floating point number (with decimals) and proceed from there. Most programming languages would prefer to use 0.5 as opposed to 1/2 because the later might conflict with the syntax of the languages. In this article, I will discuss my attempt to work with fractions in one of the PHP projects that I have done.   They start with the CSS to handle the output before moving into the PHP code. The code given will take in a decimal number and do its best to match it up with a fraction string value out of an array. The result is the echoed out with sup and sub tags to create the correct effect.

(InfoWorld) - For the second week in a row, independent security researchers have fixed a hole in Microsoft Corp.'s software. On Friday, Determina Inc.Â published a free patch for a critical bug in an ActiveX control (called WebViewFolderIcon) that is used by Windows' graphical user interface. Security experts consider the flaw to be critical because it could be exploited by attackers to run unauthorized code on a victim's PC. To make this happen, the victim would have to visit a Web site with Internet Explorer (IE) and allow it to run a malicious ActiveX control. Security researcher HD MooreÂ published details of the bug on July 18, but he recently added attack code that exploited the flaw to his widely-used Metasploit hacking toolkit. Determina says that the availability of the Metasploit code has boosted the risk of attacks. There seems to be no shortage of Windows attacks this week. On Tuesday, MicrosoftÂ issued a rare emergency patch for a separate problem in Outlook and IE's Vector Markup Language (VML) rendering engine, after that flaw was widely exploited by attackers. And criminals have also launched extremely limited attacks that exploit an unpatched flaw in PowerPoint. The VML flaw had first been fixed four days ahead of Microsoft's patch by a group of security researchers calling themselves the Zeroday Emergency Response Team. This latest bug is not likely to be as widely exploited as the VML vulnerability, Moore said. "This bug is not as severe as the VML flaw, since it depends on ActiveX, and would not be exploitable by default through Outlook," he said in an e-mail. Nevertheless, Microsoft found the issue to be serious enough to meritÂ a security advisory, published Thursday. Microsoft plans to patch the WebViewFolderIcon flaw in its next scheduled set of security updates, due Oct. 10. So far, Microsoft doesn't know of "any attacks attempting to use the reported vulnerability or of customer impact at this time," the security advisory states. Microsoft does not recommend that users install third-party patches, because this software has not gone through the rigorous quality assurance testing process that Microsoft applies to its security updates. Determina's patch works on Windows 2000, XP and 2003 systems. Â

Stop us if you've heard this before Security experts warn a new, unpatched vulnerability in Internet Explorer might be used to spread malware. A flaw in Microsoft's Direct Animation Path (daxctle.ocx) ActiveX control, rated as critical by Secunia and other security watchers, has spawned proof of concept code but has not yet become the subject of widespread, hostile attack. Memory corruption is possible even on a fully patched Windows XP system.â¦
