Need advice about zip rar files

Here's wishing you all a very happy New Year!! Mr Greenhorn is back again! I have a question about zip and rar files. As some of you may remember, this is my first Mac, so I'm used to using the zip/rar programme on my old Windows O/S. Now I receive zip/rar files and can't open them. What is anyone's advice about downloading the zip/rar programme onto my Mac? Any particular pro's and con's? Any particular site to download from? Now my Mac has a compression programme included which converts files to zip files, but is that compatible to the actual zip/rar programme? And finally, where is the advantage to compressing files? Is it only for uploading or is there some benefit to having files 'compressed' on your actual laptop?

Hi There
Mac OS X has a built in Archive Utility which doesn't support .rar files. To uncompress rar files you will need a utility like RAR Expander or Stuffit Expander both are free. I suggest doing a search on MacUpdate (http://www.macupdate.com) or VersionTracker (http://www.versiontracker.com) to find a programme that you like.
I personally don't see any advantage with keeping compressed files on your laptop (unless the archives being used often for emailing, uploading to websites etc). Compressing files does save disk space but if you get to the point where you need to compress your files to gain disk space then I suggest buying an external HD or a bigger internal HD.
Hope this helps

Need to join multiple rar files - help please!

I need to join multiple rar files. what is the equivalent of winRAR or something along those lines for macs? I know of Chunk Joiner, but I've never seen one that has been updated for the new macbook pros.
thanks!

OK, I think MacHacha will do the job for you, if not look at RAR Expander or The Unarchiver

Need advice about transfering files

Hello. I just got a new mac through an education deal at school. I hate this process of transferring files from one computer to the next but have never done it from one Mac to another before so thought it would be pretty smooth. Im new to the whole Migration Assistant and so need some advice about what to do next.
I tried using migration assistance upon first turning on my new mac but was using wireless and it just wasnt working. My computer kept saying my new mac wasnt responding and I kept having to select ok or cancel every minute and with 15 hours to go, i thought f^*# it. So I decided to just start the computer up and manually transfer files. Then I found an ethernet cable, turned file sharing on and am using my public folder to transfer but its turning into The Most Tedious task and things arent transferring properly (like certain folders arent copying contents, just the folder itself).
Now Im wishing I could have used migration assistant from the start but what can you do. I cant just re-install the mac os software and try again because before we got our new macs they installed some programs for us, like Logic, and I dont really wanna mess with that.
Whats my best option at this stage? Ive transferred about a gig of pictures and documents over so far (and I think my old hard drive is about 60 gig full) but theres a bunch of other little things like iphoto, imovie, garageband, stickies, as well as big folders of music (and itunes - playlists etc) that I wanna make sure get copied in entirety. Will migration assistant handle that? Is it best to delete the stuff Ive transferred so far and let it start fresh? What would you do?
Sorry my post is so long

Also, now that I have an ethernet cable, if I go ahead and use migration assistant to transfer the account from my old computer, will Logic only be available through the new account I have set up on my new computer? Would I have to log out of one account and into the other and back and forth to access the different files/programs? Any help would be much appreciated

Need advice about making a application log over every task succsessfully done to a target

Hi!!!
I need an advice about how to make an application log over every task succsessfully done to a target with an unique ID.
I have developed an application with several tasks on the menu which have to be done in a certain order to program and test a target board,
and the user want a log about which tasks are done to the target, so it is easy to know which step is next on the menu (It is a very routinebased job).
Do somebody have any good advice on how this can be done in a cleaver way ?
Best regards,
A

Need advice about coalesce and deallocate unused space

Hi experts;
Here looking for an advice about coalesce and deallocate unused space.
I got this tablespace with 87% full, one of the table in that tablespace has 1,150,325 records. I'm going to delete 500,000 records from that table, but to release the space used by those records I understand that I need to execute other procedure. I was reading about coalesce tablespace and deallocate unused space.
I found that apparently, both process can help me to free space. If you want to share with me your comments, about advantages or disadvantages about them, in order I can take the best solution?
Thanks for your comments.

Hi
after deleted rows, the high water mark is still the same and so the size of the table. you need to bring down the water mark
here is what you need to do to bring down the high water mark. We do this monthly for performance purpose.
This is an EBS R12 system but the procedures are the same for EBS database or non EBS database.
After you purge or delete data in a table
1) alter table APPLSYS.WF_ITEM_ATTRIBUTE_VALUES move; <-- this operation will invalidate all indexes attache to the table
2)select owner, index_name, status from dba_indexes -- list all invalid object for user APPLSYS
where table_owner = upper('APPLSYS')
and
status NOT IN ('VALID','N/A');
3)spool idxrebuild.sql --generate script to rebuild indexes.
select 'alter index ' ||owner||'.'||index_name ||' rebuild online;' from dba_indexes
where table_owner = upper('APPLSYS')
and
status <> 'VALID';
4) run idxrebuild.sql -- to rebuild indexes. -- at this point if you check spaces on the table, it is still the same, you need to run #5
5)exec fnd_stats.gather_schema_stats ('APPLSYS'); --fnd_stat is for EBS system you can replace with the database equivalent command.
use this statement to count the block before and after the operation to see the different.
select DISTINCT(SEGMENT_NAME), count(blocks) "Total Block" from dba_extents
where
owner IN ('APPLSYS')
AND segment_name = 'WF_ITEM_ATTRIBUTE_VALUES'
Hope this help.

I need advice about being part of the Twitter Army of Awesome Help

I am grateful for the fact of Mozilla and I use Twitter a lot.
Although I am not technically competent, I do have experience of using Mozilla and Thunderbird for quite some years and am willing to share my experience.
I obviously do not want to make matters worse for questioners and need some advice about how to begin.
Is there a Forum where Folk such as me can share experiences of answering Tweets and also just be given examples how the system works, please, or might it be better for me to resign before I start rather than cause complications for anyone?

Thanks - I hope to have a check there, when I have more time, meanwhile I see that separately I have been sent an email asking for my experience etc.. -
I plan to attend to that when I am less pressed for time, it may not be for some while though - my spirit is willing but resources few, but if I just learn to do some small things it spreads the load - and I guess I have made a very small start - I have wondered about it for years but that Awesome Tweet was the prompt that got me this far!

// get a list of files from current directory
File f = new File(".");
String files[] = f.list();
for (int i=0; i<files.length; i++) {
System.out.println("Adding: "+files);
FileInputStream fi = new
FileInputStream(files[i]);
origin = new
BufferedInputStream(fi, BUFFER);
ZipEntry entry = new ZipEntry(files[i]);
out.putNextEntry(entry);
int count;
while((count = origin.read(data, 0,
BUFFER)) != -1) {
out.write(data, 0, count);
origin.close();

Don't cross-post!

And use code tags already.
The referenced thread already has advice for you (and no, we will not do it for you, you've already been given an example of how to do it, it is up to you to at least attempt it).

Need advice about certification: do J2SE 1.4 or wait for 1.5 to go out?

I need advice here! I am studing for Java Programmer certification (310-035) and I know now that the certification does not have any expiration date, instead it's version based. So, if I get now a J2SE 1.4 certification, soon it will be outdated... I guess!
Does anyone know or have any ideia of WHEN java 1.5 sdk will be avaliable, and anyone can tell me how long it will take for a new 1.5 programmer certification be avaliable for general public?

Do both. 1.5 is far enough away that you do not want to wait for it.
And besides, 1.5 has enough new stuff in it that you'll want to recertify anyway.

Need advice about a WiFi set-up

Dear Gang,
I want to have a pure 802.11n network using the 5 ghz spectrum and the wide array setting. However, I have one desktop computer that is 802.11g. I'd like to run a 25 ft. Cat 5 cable to one of the LAN ports on the TimeCapsule and then shut-off the WiFi on this computer. However, strangely enough, I've always had all my computers (even desktops) networked via WiFi so I don't know how well using the LAN works.
What are the thoughts of the group?
I know that ethernet should give me greater speeds to the TC's hard drive and should solve my problem with bringing a non-802.11n machine in to a "pure" network, but I don't want to do so if the set-up is arduous or if doing so makes me lose a lot of features that I get in an all WiFi network.
TIA,
Mark

dwb,
I'll definitely take your advice about the ethernet cables - thank you.
Your info is reassuring as it means that my dual G5 will get a little more life out of it by connecting it in to my "pure" system via ethernet.
Two other quick questions:
-should I connect my new iMac via ethernet to the router, too, even though it's capable of going on my system in 802.11n 5ghz?
-also, as an aside, I'm trying to figure out if my new 802.11n network will equal my current 802.11g network in terms of distance as I have an Apple TV that's a few rooms over. That Apple TV gets about 4 bars of signal from my current network. Do you think that 802.11n at 5 ghz will have an equivocal range?

Need advice about best characterset for XMLDB

Hi,

Please, give me an advice about best character set
configuration for XML DB.
During installation Oracle istallator suggests
charset =AL32UTF8 for multilingual data and ncharset=

Is it good settings for database, which will be

Need advice about files back up

Could you please tell me how I can easily (I am not technically competent) backup the following:
- Microsoft security updates
- Norton security updates
- other downloaded software program updates
- emails
- Internet "Favourites" list
- desktop display settings
- any other important files you suggest
Your help would be gratefully appreciated.

It sounds like you need a disk cloning program similar to the software used by Toshiba for their product recovery discs.
There are several commercial products like Norton Ghost for example but there are also free ones like Terabyte Unlimited CopyWipe:
http://www.terabyteunlimited.com/copywipe.html
Unfortunately I have used neither program so I really can't comment on how good they work.

Need advice about importing a Powerpoint file into FCE 3.5

I am editing a live event (a 2 camera shoot). A 3 minute Powerpoint projection was shown with a music track.
Our recorded footage is useable, but I thought that I could import the original PPT file from the producers (two teenagers), for better picture quality. I managed to get Keynote to Save it as a .mov file.
However the Producers seem to have re-edited the PPT and now there is certainly no Sync with the original. The duration is much longer than the original. The image quality is however brighter and crisper than our Rushes.
Can anyone suggest any Tips on working this way with PPT. (yes, I know - no-one in their right mind would ......)
My work-around seems to be just edit as a Fit-to-Fill and hope for the best.
I am not expecting too many brilliant ideas but if there is anyone out there witha solution, I will be very grateful.
Thanks in advance
Freesh

Matt,
Thanks for your lonesome Reply. Not too many people going down this route!
I have actually managed to edit it in as a Fit-to-fill and have previewed it within the sequence. However my programme is 90 minutes long and I have had to move on. I will come back to it again to see if I can improve anything probably tomorrow - Thursday.
I cant imagine I will use this avenue too often, so I dont want to seek perfection here or waste your time. There is only a tiny budget - it is a good cause really. We do these things.
But I am alaways generally interested in building my knowledge base. I didn't find any problem in converting or importing it to FCE HD 3.5. I am running 10.4.7. I saved it as a QT Pro 7.04 .mov. I dont know too much of the technical aspects, only when something goes wrong and I have to.
I did force it to Render. But I re-edited so I haven't yet bothered with it again. I am interested to see what it looks like on a TV (I dont have a dedicated monitor at present) and on the eventual DVD which is the Delivery format.
I will post back or email you with any more info when I finish the edit if you would like?
Thanks again
Freesh
