  • How can I line up columns with Perl's printf when the value might be a number or a string?

    - by user317203
    I am trying to output a document that looks like this (more at http://pastebin.com/dpBAY8Sb): 10.1.1.1 100 <unknown> <unknown> <unknown> <unknown> <unknown> 72.12.148.186 94 Canada Hamilton ON 43.250000 -79.833300 0.00 72.68.209.149 24 United States Richmond Hill NY 40.700500 -73.834500 611.32 72.192.33.34 4 United States Rocky Hill CT 41.657800 -72.662700 657.48 I cannot find how to format the output I have to have a floating poing and format the distance between columns. My current code looks something like this. if (defined $longitude){ printf FILE ("%-8s %.6f","",$longitude); }else{ $longitude = "<unknown>"; printf FILE ("%-20s ",$longitude); } The extra "" throws off the whole column and it looks like this (more at http://pastebin.com/kcwHyNwb). 10.1.1.1 100 <unknown> <unknown> <unknown> <unknown> <unknown> 72.12.148.186 94 Canada Hamilton ON 43.250000 -79.833300 0.00 72.68.209.149 24 United States Richmond Hill NY 40.700500 -73.834500 571.06

  • How do I determine the revision number of an Android build?

    - by hermo
    I know how to get the API level, android.os.Build.VERSION.SDK_INT, but there are also several revisions of each level release, e.g. for 2.1 there's rev 1 and 2. How do I determine the revision of a build? The reason i'd like to know this is that I have a workaround for a bug in Android 2.1 (and 2.2), and this workaround will break the moment the corresponding bug is fixed. So right now i'm in the odd position of hoping that the bug won't be fixed (at least not until I can find an answer to above question).

  • Is there any sence in performing binary AND with a number where all bits are set to 1

    - by n535
    Greetings everybody. I have seen examples of such operations for so many times that i began to think that i am getting something wrong with binary arithmetics. Is there any sense to perform the following: byte value = someAnotherByteValue & 0xFF; I don't really understand this, because it does not change anything anyway. Thanks for help. P.S. I was trying to search for information both elsewhere and here, but unsuccessfully.

  • How to know which process hold a semnum with a specific number?

    - by Daniel
    For the following truss output, we can see the process post to 11 processes whose semnum is 49,32, ..etc, is there anyway to find out which process hold semnum 49, and which process holds setnum32, etc? /1: semop(67108928, 0xFFFFFFFF7FFF9F4C, 11) = 0 /1: semnum=49 semop=1 semflg=0 /1: semnum=32 semop=1 semflg=0 /1: semnum=52 semop=1 semflg=0 /1: semnum=41 semop=1 semflg=0 /1: semnum=40 semop=1 semflg=0 /1: semnum=55 semop=1 semflg=0 /1: semnum=46 semop=1 semflg=0 /1: semnum=35 semop=1 semflg=0 /1: semnum=37 semop=1 semflg=0 /1: semnum=48 semop=1 semflg=0 /1: semnum=39 semop=1 semflg=0

EDIT: Well, off course i assume that someAnotherByteValue is 8 bits long, the problem is that i don't get why so many people ( i mean professionals ) use such things in their code. For example in Jon Skeet's MiscUtil there is: uint s1 = (uint)(initial & 0xffff); where initial is int.

  • How to deploy a number of disparate project types?

    - by niteice
    This question is similar to http://stackoverflow.com/questions/1900269/whats-the-best-way-to-deploy-an-executable-process-on-a-web-server. The situation is this: I'm developing a product that needs to be deployed to a web server. It consists of 4 website projects, a background service, a couple of command-line tools, and two assemblies shared by all of these components. Now, I also happen to administer the server that this product will be deployed on. So I'm familiar with everything that may need to be done to perform an update: Copy website files Replace the service binary Install updated components in the GAC Configure IIS Update database schema After some research it seems that, to reduce deployment time and to be able to let the other sysadmins handle deployment, I want to deploy all of these as an MSI, except that I don't know a thing about installers. I know VS can generate web deployment projects, but where do I go from there? Being able to simply click Next a few times on an installer is my goal for deploying updates. It would also be nice to modularize it, so for example, I could distribute the four websites among multiple servers and have everything appear as individual components in the installer, and as one entity in Add/Remove Programs. Is all of this too much to ask in a single package?

  • How do you print a limited number of characters?

    - by Mike Pateras
    Sorry to put a post up about something so simple, but I don't see what I'm doing wrong here. char data[1024]; DWORD numRead; ReadFile(handle, data, 1024, &numRead, NULL); if (numRead > 0) printf(data, "%.5s"); My intention with the above is to read data from a file, and then only print out 5 characters. However, it prints out all 1024 characters, which is contrary to what I'm reading here. The goal, of course, is to do something like: printf(data, "%.*s", numRead); What am I doing wrong here?

  • usort - more parameters

    - by pgfonline
    Hallo, how can I pass more parameters to usort? I have different functions, which are very similar in structure, I want to have just one function: <?php $arr = array( array('number' => 100, 'string'=>'aaa'), array('number'=>50, 'string'=>'bdef'), array('number'=>150, 'string'=>'cbba') ); usort($arr, 'sortNumberDesc'); //How can I use just a single function? //How can I pass further parameters to usort? function sortNumberDesc($a, $b){ $a = $a['number']; $b = $b['number']; if ($a == $b) return 0; return ($a > $b) ? -1 : +1; } function sortNumberAsc($a, $b){ $a = $a['number']; $b = $b['number']; if ($a == $b) return 0; return ($a < $b) ? -1 : +1; } //I want to do the same with just one function: //Sort ID is the search index, reverse DESC or ASC function sort($a, $b, $sortId='number', $reverse = 0){ $a = $a[$sortId]; $b = $b[$sortId]; if ($a == $b) return 0; if($reverse == false) return ($a > $b) ? -1 : +1; else return ($a < $b) ? -1 : +1; } print_r($arr); ?>

  • How can you tell MYSQL to TRIM the X number of characters, beginning from the Back?

    - by Tim
    How do I write the following in MYSQL? SELECT SUBSTRING(value - (1 TRAILING CHARACTER)) FROM table; Basically substring(value, 2) trims the first letters. But I need to trim the last letters. I can't use substring(value, -4, 3) because I don't know the length of the value. Here's another example: SELECT * FROM table WHERE SUBSTRING(value - (4 TRAILING CHARACTER)) in (SELECT SUBSTRING(value - (1 TRAILING CHARACTER)) FROM table);

  • How do I select distinct rows where a column may have a number of the same values but all their 2nd

    - by Martin Rose
    I have a table in the form: test_name| test_result | test1 | pass | test2 | fail | test1 | pass | test1 | pass | test2 | pass | test1 | pass | test3 | pass | test3 | fail | test3 | pass | As you can see all test1's pass while test2's and test3's have both passes and fails. Is there a SQL statement that I can use to return the distinct names of the tests that only pass? E.g. test1
