Anyone with a solution for evaluating a cell with multiple arbitrary operands?

comment How does the Finder refresh in OS X Mountain Lion?
Only one restart later to find that the bug reoccurs :-( After that I killed UserEventAgent, and then refreshing worked fine, but Finder jumped to 100% CPU. Killed and thereby restarted Finder. Bug there again. Killing UserEventAgent again did not help this time. I am at the end of my testing for now. Think I'll do a fresh install somewhen...

comment How does the Finder refresh in OS X Mountain Lion?
Finally Finder 10.6.8 refreshes properly again! Did so much within my user account, that I'm not sure what actually fixed it & am certainly not trying to reproduce the bug now that Finder works again! But to share some experience my hot guess is: From within the control panel Users I deleted unused accounts & the group access_bpf (needed for Wireshark network device), enabled, used, then disabled Fast User Switching. Besides this, within ~/Library I checked Services & Scripts, erased Contextual Menu Items (empty but who knows...) and LaunchAgents/com.apple.FolderActions*.

I tested this on the guest account, and there the bug does not occur! So Finder.app is definitely not corrupted, and the cause of the problem must be somewhere within my home directory. I had erased com.apple.finder.plist and the .DS_Store files in the troubled directories, and restarted Finder, and also logged out and in again, but the problem still persists. I can only assume that my file/folder permissions are not as supposed to be or that a 3rd party software integrated into Finder or Filesystem events causes the trouble. (Contextual Menu) Services? Dropbox? Any ideas?

comment Is there a way to refresh a Finder file listing?
Thanks for this workaround. Maybe I create a daemon which runs this script once per second (but that's not very power efficient), although that polling approach is not very power efficient, would prefer Finder to automatically properly update based on file system events. Isn't there a fix for this? (Erasing com.apple.finder.plist and .DS_Store in affected folders did not fix it for me).

comment Why is my MacBook Pro's fan constantly on at 6000RPM?
I also once experienced a similar issue on a MacBook Pro 4,1 (A1260). See my report (including miraculous solution for which I don't know the true cause): Fans rotating at maximum although reported temperatures are very low.

So as long as a file is actively written to (programmatically speaking: file handler open), the responsible process (writing app, kernel or possibly fsevents or similar fs monitoring processes) seem to not trigger Finder to refresh, only if the event "finished writing" occurs. Makes sense, as the Finder would need to refresh a lot otherwise (even if reduced to certain refresh intervals). I think this is by design. My script was a loop of consecutive open/write/close processes, thus triggered the refresh, whereas the other observed cases were open … write … write … write … close cases.

Same effect in ~/Downloads. While downloading a file from Chrome, its size is not updated, although its written to constantly. A refresh is triggered, either by navigating our and back in again, or by creating a new or renaming an existing folder within ~/Downloads. When the download finished the size and timestamp are updated correctly. But not while the download progress.

Btw, I am on 10.6.8. Sadly, the refreshing bug still occurs. Example of a current manifestation adb backup -apk -all -f ~/Backups/android.ab. android.ab constantly shows the same file-size although its constantly being written to. If I point my fast growing file script at this directory, both the file growing and the file android.ab regularly refresh their file size! It seems that some write operations trigger a refresh, while others don't. I don't know specifics. Maybe certain Services that I use cause that.

comment How to fix “512 bytes per sector” to “4096 bytes per sector” for an “Advanced Format” 4K sector USB hard drive?
I connected a Toshiba DT01ACA300 3TB via eSATA cable to the eSATA ExpressCard AKE BC338 in my MacBookPro2,2 running OS X 10.6.8. diskutil shows me 512 byte sectors, whereas stat shows 4096. smartctl shows me 512 logical / 4096 physical. These differing infos assert nothing, just leave me insecure, not really knowing what's happening under the hood. I have to trust my BlackBoxes I guess. ;-) Hoping that one of the involved devices just misreports and the optimum happens in reality.

Adding small files frequently: cd ~/Desktop/update/;i=1;while [ $i -lt 1000 ];do mkfile 0 $i;(( i++ ));echo "File Nr $i";sleep 1;done Slowly growing file: cd ~/Desktop/update/;mkfile 1000 1kb;mkfile 0 growing;i=1;while [ $i -lt 1024 ];do cat 1kb >> growing; echo "$i kB";(( i++ ));sleep 1;done Fast growing file: cd ~/Desktop/update/;mkfile 1000000 1mb;mkfile 0 growing;i=1;while [ $i -lt 1024 ];do cat 1mb >> growing; echo "$i mB";(( i++ ));sleep 1;done

Mac OS X Finder's refreshing behavior differs a bit depending the the occurring changes: Single file growing at kB/sec rates (instant), many new small files (1-3 secs), fast growing files (mB/sec) refresh a bit slower (max 3-4 secs). Full Finder Refresh Test Suite which for provoking different refresh behaviors in next post.

Nr.3 rm ~/Library/Preferences/com.apple.finder.plist ; killall Finder was definitely the solution! After that my desktop icon sizes&grid&positions were broken, but with some pref tweaking + cp /Volumes/TimeMachine/Backups.backupdb/MacName/Latest/LocalDisk/Users/Name/Deskto‌​p/.DS_Store ~/Desktop/; killall Finder successfully restored. Then wrote test script! cd /path/to/refresh-dir/;mkfile 1000000 1mb;mkfile 0 growing;i=1;while [ $i -lt 1024 ];do cat 1mb >> growing; echo "$i mB";(( i++ ));sleep 1;done Finder now refreshes properly! ~Every 2-3 seconds. Prior only on leaving&reentering dir!

comment DropBox syncing all folders, again?
While Dropbox reindexes, disk read access is up at max, and network traffic is unspectacularly. This indicates that Dropbox re-reads all files (heavy disk read load), calculates their checksums, and compares this with the cloud (only very little network traffic). The question is, why it is reindexing. I cloned my HD with SuperDuper, which is doing a very exact clone, just ommiting some caches etc. Either one of Dropbox cache files/dirs was left out, or Dropbox uses inode for UID-ing files as well, and the inodeschanges of course in the clone process. Any input?

It only works if the source text cell contains a mathematical expression in the form of "a/b". Any other operator such as +-* fails. Also multiple operands such as "a+b+c-d+e-f+g" are not possible. I would like to have my source text cell with i.e. "1+2+3-4+5-6.7+8.99" and another cell evaluating the content of that source cell.
