After the hype of security in marketing campaign run by Microsoft about new security “pearl” Vista, there are the first reports of how easily someone can crash the system….

Just press Win+E – this is well known shortcut for launching Explorer and hold it for 20 sec this will cause the launch of multiple Windows Explorer instances resulting lack of system resources and crash of the system.

Unfortunately this cannot be stopped in Task manager….

Wait for patch for MS and hope that somebody will not write a hoax using this vulnerability.

After updating my Linux workstation I found that acroread produces “expr: syntax error” when started.

Quick Googling show me the solution.

  1. Open terminal.
  2. First find where acroread executable script is located – on my machine:
    whereis acroread
    acroread: /usr/bin/acroread /usr/lib/acroread
  3. Then type vi /usr/bin/acroread.
  4. After that type 418G and add *(asterisk) [move cursor after the block press i for insert and *]after second [0-9] block as shown below
    Fix acroread
  5. Then save the file [Press Esc 2 times and type :wq]
  6. Now you can use acrobat again.

NOTE: This fix is for AdobeReader_enu-7.0.9-1 for Linux. It is not tested on other versions or platforms.

EDIT: How to install AdobeReader_enu-7.0.9-1 in CentOS 5/4.x.

Navigate to –> Click on get adobe reader –>Choose .rpm version –>Click on Download –>Either Open with Software Installer or download to disk and install if you need to do it on multiple machines.
