How would I find...

Hey there, I am somewhat new to Java and I was wondering, if I had a string, how could I check it to see how many letters there are in it? Is there some sort of function to do this?

You could manually iterate over the characters with charAt() and then test Character.isLetter on each one, incrementing a count if true.
Or you could use regex's \p{Alpha}.
The first one is probably faster (but probably not signifiantly so in most contexts), and simpler if you don't know regex.
The second one leads to more compact code, and is more readable if you do know regex.

How would i find for permissions for certain directory

hello
how would i find in my web docs (/home/user/htdocs) all directories named "templates_c" so i can do a chmod on them.
they need to be writable by the app, but i think 775 is not enough, i think they might need tto be 777 or atleast o+w i believe. its for smarty template engine to write the template files on initial compilation.
i have been trying various wildcard version of find and chmod, but i dont want to foul things up.

i ran as root, it didnt find anything. there is atleast 3 of those directories in there. i had to manually set them again. there is probably more. Is there something i can change on that last command that might be keeping it from finding anything?
its just a local testing server, i had the permissions chowned to "http", but the problem comes when everytime i upload a new file across ftp when logged in as user, it goes back to user, so i ended up chowning everything to user instead.
Could you please confirm whether you tried the commands Samuvuo suggested? Please specify whether the following command found the required directories:
sudo find /home/user/htdocs -type d -name "template_c"
Although, I would personally run the command like so, cos I'm noob:
find ~/htdocs -type d -regex ".*/template_c.*"

Ask the app developer. Maybe they will tell you why... Apple will not disclose the reason to you unless you are the developer. It's entirely possible that the developer removed it.

How would you find the pitch period of a sound signal?

Hi
I have a few questions and i would like if somebody could help me even with the smallest comment on this.
How would someone be successfully estimate the pitch period (fundamental frequency) of a 5 second sound file?How would you successfully distinguish the voiced from the unvoiced parts and how would you make sure you dont mix voiced/unvoiced sections? Finally how can you find the exact points where the pitch is at its peak throughout the signal?
Any help/comment/suggesion would be much appreciated

Hello Madgreek,
After some thought I think I may have come up with an algorithm for what we have discussed. Basically, you are interested in knowing the time intervals over which you can observe any given frequency in your signal. As you had suggested, you can examine small windows of your signal and perform FFTs on each of the small windows to determine what frequency content is contained in that window. By examining all of the windows, you will see when particular frequencies are prevalent in the original signal. You'd want to use the smallest allowable window to give you the most resolution, but one that is large enough to cover an entire period of the lowest frequency (so that you don't miss this frequency).
I have attached an example program that performs this operation. The example performs this analysis on an array that represents audio data. I am basically performing multiple FFTs (for each window) and stacking these FFTs in time to form a 3D plot. By examining the 3D plot, I can then see when in time my frequencies of interest are at their peaks. Rather than graphing these plots, you may work out a different algorithm for programmatically determining and logging these peaks and times. I hope this is what you were looking for!

HT4759 how would i find my iphone if its offline?

how would i fimd my iphone if its offline?

You can't. If it's offline it can't communicate with the Find My iPhone servers. All you can do is put it in lost mode. If and when it goes back online and lost mode in implemented, you will receive an email informing you. (See http://help.apple.com/icloud/#/mmfc0f0165.)

How would I find the most common value every nth row in a column

SCENARIO 1
I have a column with a series of numbers in c1:c1000 as follows:
2
2
3
1
1
4
2
3
1
2...
and I would like to find the most common value for every nth (in this case, second) row.
SCENARIO 2
Originally, I created a separate column in J and used this to find a value of 0 or 1 via a filter to label the rows odd or even. I was then going to create two separate columns, one for even rows of data and another for odd rows of data to separate them and perform functions on each column. But I do not know how to copy just the filtered data to one of the new columns to apply the MODE function (or any other for that matter).
Perhaps my question should be: after applying a filter, how do i copy just the visible filtered data of every nth row to a new column in my spreadsheet while retaining the original column with all rows of data?
BACK TO SCENARIO 1
If I do not need to go through this effort, I would just apply the MODE function (or AVERAGE or SUM) to every nth row in the original data column.

Since Index and Offset were already taken, I used INDIRECT(ADDRESS()) in my example.
Here's how I approached it:
Expressions are as follows...
Data Subset, Column A, Row 2: =IF(StartingRow :: A, 1, NSelector :: $A)
Subsequent rows in Column A: =IF(ROW()<COUNT(Input :: $B)/NSelector :: A:$A+2, A2+NSelector :: $A, "")
Data Subset, Column B, Rows 3
throuth the last: =IFERROR(INDIRECT(ADDRESS(A+1, 2, ,,"Input")), "")
Stats, Column A, Row 2: =IFERROR(MODE(Data Subset :: B), "No Mode")
Stats, Column B, Row 2: =COUNTIF(Data Subset :: B, A)
Lots of ways to skin this cat.

How would you find images without a tag?

II just installed Elements 8. have several folders of images. none of them have tags. I would like to add tags as I add folders. Seems like it would help to find the images that do not have any tags and then associate the correct tage wiith the images.

How would I find my ipod touch after remote wiping?

I lost my ipod and someone stole it at my work I know for fact because it connected to the internet. It wiped but now just figured out I can't locate it, is there a way I can find it? im positive the wipe wont clear out my ipod the person will obviously delete everything and will completely see everyting i had on it. really personal stuff and will ruin my reputation. when seeing it, i learned my lesson.

If you wiped your iPod or if the person restored the iPod, the iPod will be completely erased, including the ability for you to locate or do anything to the iPod remotely. The only way to find your iPod is the old fashioned way, like if you lost your wallet.
The serial number will only identify the iPod as yours if it is recovered.

How would I find a maximum among 4 columns

Let's say I have col1, col2, col3, col4 in my BMM - I need to compare them and select the largest column. So far, it seems as I need to write a CASE statement. Is there another way to do this?

not that i know of.
if you need case statement, this will save you some time:
case when Table.column1 >=
case when ifnull(Table.column2, 'somelternatevalue') >= ifnull(Table.column3, 'somelternatevalue') then case when ifnull(Table.column2, 'somelternatevalue') >= ifnull(Table.column4, 'somelternatevalue') then Table.column2 else Table.column4 end else case when ifnull(Table.column3, 'somelternatevalue') >= ifnull(Table.column4, 'somelternatevalue') then Table.column3 else Table.column4 end end
then Table.column1
else
case when ifnull(Table.column2, 'somelternatevalue') >= ifnull(Table.column3, 'somelternatevalue') then case when ifnull(Table.column2, 'somelternatevalue') >= ifnull(Table.column4, 'somelternatevalue') then Table.column2 else Table.column4 end else case when ifnull(Table.column3, 'somelternatevalue') >= ifnull(Table.column4, 'somelternatevalue') then Table.column3 else Table.column4 end end

How would I find the first date a shipment occurred for a specific material

We need to determine when an item is new and set the u201Cnew item indicatoru201D to True. Once a material is considered new, the u201Cnew item indicatoru201D should remain true for a period of three years. Each week, a process needs to run that looks at the material master data (First Arrival Date) and compares that with the current date to check if three years has passed. If three years has passed, then the u201Cnew item indicatoru201D should be set to False. Initially, all items need to go through this process to set the new item indicator.

Hi,
You could setup a DSO keyed by material in which you have a date key figure that is set to MIN aggregation in the transformation. If you load that DSO from your shipments, it will automatically keep the date of the first shipment.
You could then run a periodic load that could be picking up all the materials whose date in the DSO is older than 3 years and which are still marked as NEW_ITEM. In that load you then update the NEW_ITEM status.
Cheers
Henry
