Re: After upgrading my PC from Debian Sarge to Debian Etch
Quoting Omer Zak, from the post of Sat, 12 May: I have at last upgraded my desktop PC from Debian Sarge to Debian Etch. At one stage, the aptitude package was removed. But I used dselect to re-install it and so could proceed with installation. Moral: avoid marking packages as automatic in aptitude, unless you really need them only when another package is installed. well actually I haven't ran dselect in years... I would run apt-get install aptitude. I don't think you mark packages as auto, it's more like aptitude marks them auto by default if you never selected them. What you want to do is once you selected a package and it auto-added a few more automatic packages, go over the list and force select them if you want them to stay regardless of the package that added them. -- One for the books Ira Abramov http://ira.abramov.org/email/ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Copying and pasting Hebrew text Firefox-OOo
On Fedora Core 6, I am trying to copy and paste Hebrew text from Firefox 2.0.0.2 to Open Office 2.2 Writer / Calc. The text is encoded in ISO-8859-8 (one of several Hebrew encodings) from the website 999.co.il. When I paste into either Writer or Calc, the text is backwards (left to right). What is the solution/ workaround to copying and pasting from Firefox? Thanks in advance.

What you want to do is once you selected a package and it auto-added a few more automatic packages, go over the list and force select them if you want them to stay regardless of the package that added them. Actually my strategy is sort of the other way around - I try to keep as many packages as I can marked as auto unless I'm absolutely sure I really need them independent of other packages (e.g. perl modules, or development libs). That way I know my system doesn't have too much lint left behind from search and learn expeditions through the vast fields of apt-cache search (I also use purge instead of plain remove to keep the lint down). Another couple of morals I'd like to add from Omer's story: 1. Carefully and patiently go through the first screen you see after hitting g (go) in aptitude and make sure you like what you see, so you'll catch any nasty surprises before they actually happen. 2. When upgrading between major releases, I've seen many times recommendations to upgrade the administration tools (apt, dpkg, aptitude) first on a round of their own, since the new version usually have many bug fixes and important features to handle the upgrade better then the version which exists in the older release. These will usually also drag a bunch of other basic packages they depend on but hopefully you'll get the newer, smarter version handling depenencides for most of your package's upgrade.

Re: Fwd: 4GB Memory question
Hi, Quick answer is no. A bit longer answer is: 1- PAE refers to a certain technology avail. in the CPU which allows 32bit kernels to address larger address spaces. 2- Hugemem is a technology which changes the ratio between the user space and kernel space from 3GB/1GB to 4GB/4GB. (So the actually virtual memory refers to the same physical memory) It just gives your processes a bit more a breathing space before starting unmapping/mapping memory from highmem zone to the normal zone. 3- In RHEL5 there's no need for a specific hugemem kernel anymore as the kernel is smart enough to decide during boot what kind of technology should it use. - Noam On 5/13/07, Ira Abramov [EMAIL PROTECTED] wrote: Quoting Noam Meltzer, from the post of Sat, 12 May: Actually, that what PAE means according to wikipedia (http://en.wikipedia.org/wiki/Physical_Address_Extension): yes I know PAE, so that was my questions - does PAE in the kernel package name refer to the same patch as the hugemem package of older RHELs? -- Waste of space Ira Abramov http://ira.abramov.org/email/ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

(So the actually virtual memory refers to the same physical memory) It just gives your processes a bit more a breathing space before starting unmapping/mapping memory from highmem zone to the normal zone. Actually, if you read the original 4/4 patch, you will see that the two are not as unrelated as it may sound. The purpose of the 4/4 split (which makes every call into the kernel more expensive, as it now requires switching the MMU address space) was NOT to give user space processes more breathing space. The purpose was to give the KERNEL more breathing space. The problem was that with PAE and several GB of memory, the kernel spent most of its 1GB address space on keeping track of where all its memory resides, and did not have enough memory for doing, well, pretty much anything else. The 4/4 split was not built to allow userspace the extra 1GB. The 4/4 split was meant to allow the kernel an extra 3GB. This is unlike the case for Windows, where Windows 2000 advanced server had a revolutionary 3/1 split, unlike the traditional 2/2 split for Windows 2000 server and workstation. I don't know what splits XP uses. 3- In RHEL5 there's no need for a specific hugemem kernel anymore as the kernel is smart enough to decide during boot what kind of technology should it use. That does not make sense to me. The kernel can find out whether it needs more than 1GB for the kernel space during boot according to the amount memory available, and it can decide whether it needs PAE. I don't see how it can decide whether any user space program needs more than 3GB of space, however, during boot. - Noam Shachar = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
