• flash dynamic textfield, multiline and wordwrap acting funky.

  - by pfunc

  I have this weird thing happening with flash and a dynamic textfield. Basically, someone rolls over a marker on a map, and a tooltip pops up with a dynamic textfield. The textfield is set to multiline=true and wordwrap = true, and I defined a specific width of 160 pixels. The problem is, some of my text is jumping to the next line, some of it is just getting cut off. So if I have a line like "The Cat Jumped Over the Box", On one line I will see "The Cat Jumped" and on the next line I would see "the Box". It looks like it is masking out the "over" line and not pushing it to the next line. It's not doing this for everything, just some longer lines. This is a really weird bug and I have tried for 8 hours to get this fixed. Has anyone ran into this problem before?

• Getting the uptime of a SunOS UNIX box in seconds only

  - by JF

  How do I determine the uptime on a SunOS UNIX box in seconds only? On Linux, I could simply cat /proc/uptime & take the first argument: cat /proc/uptime | awk '{print $1}' I'm trying to do the same on a SunOS UNIX box, but there is no /proc/uptime. There is an uptime command which presents the following output: $ uptime 12:13pm up 227 day(s), 15:14, 1 user, load average: 0.05, 0.05, 0.05 I don't really want to have to write code to convert the date into seconds only & I'm sure someone must have had this requirement before but I have been unable to find anything on the internet. Can anyone tell me how to get the uptime in just seconds? TIA

• Python regular expression implementation details

  - by Tom

  A question that I answered got me wondering: How are regular expressions implemented in Python? What sort of efficiency guarantees are there? Is the implementation "standard", or is it subject to change? I thought that regular expressions would be implemented as DFAs, and therefore were very efficient (requiring at most one scan of the input string). Laurence Gonsalves raised an interesting point that not all Python regular expressions are regular. (His example is r"(a+)b\1", which matches some number of a's, a b, and then the same number of a's as before). This clearly cannot be implemented with a DFA. So, to reiterate: what are the implementation details and guarantees of Python regular expressions? It would also be nice if someone could give some sort of explanation (in light of the implementation) as to why the regular expressions "cat|catdog" and "catdog|cat" lead to different search results in the string "catdog", as mentioned in the question that I referenced before.

• Store value of os.system or os.popen

  - by chrissygormley

  Hello, I want to grep the error's out of a log file and save the value as an error. When I use: errors = os.system("cat log.txt | grep 'ERROR' | wc -l") I get the return code that the command worked or not. When I use: errors = os.popen("cat log.txt | grep 'ERROR' | wc -l") I get what the command is trying to do. When I run this in the command line I get 3 as thats how many errors there are. Can anyone suggest another way? Thanks

• LINQ To Entities - Items, ItemCategories & Tags

  - by Simon

  Hi There, I have an Entity Model that has Items, which can belong to one or more categories, and which can have one or more tags. I need to write a query that finds all tags for a given ItemCategory, preferably with a single call to the database, as this is going to get called fairly often. I currently have: Dim q = (From ic In mContext.ItemCategory _ Where ic.CategoryID = forCategoryID _ Select ic).SelectMany(Function(cat) cat.Items).SelectMany(Function(i) i.Tags) _ .OrderByDescending(Function(t) t.Items.Count).ToList This is nearly there, apart from it doesn't contain the items for each tag, so I'd have to iterate through, loading the item reference to find out how many items each tag is related to (for font sizing). Ideally, I want to return a List(Of TagCount), which is just a structure, containing Tag as string, and Count as integer. I've looked at Group and Join, but I'm not getting anywhere so any help would be greatly appreciated!

• Why is the meaning of “ours” and “theirs” reversed with git-svn

  - by Marc Liyanage

  I use git-svn and I noticed that when I have to fix a merge conflict after performing a git svn rebase, the meaning of the --ours and --theirs options to e.g. git checkout is reversed. That is, if there's a conflict and I want to keep the version that came from the SVN server and throw away the changes I made locally, I have to use ours, when I would expect it to be theirs. Why is that? Example: mkdir test cd test svnadmin create svnrepo svn co file://$PWD/svnrepo svnwc cd svnwc echo foo > test.txt svn add test.txt svn ci -m 'svn commit 1' cd .. git svn clone file://$PWD/svnrepo gitwc cd svnwc echo bar > test.txt svn ci -m 'svn commit 2' cd .. cd gitwc echo baz > test.txt git commit -a -m 'git commit 1' git svn rebase git checkout --ours test.txt cat test.txt # shows "bar" but I expect "baz" git checkout --theirs test.txt cat test.txt # shows "baz" but I expect "bar"

• How to send EOF to stdin in paramiko?

  - by Alexandru

  I would like to execute some program through ssh and redirect its input from a file. The behaviour of the following code: channel.exec_command('cat') with open('mumu', 'r') as f: text = f.read() nbytes = 0 while nbytes < len(text): sent = channel.send(text[nbytes:]) if sent == 0: break nbytes += sent should be equivalent to (assuming public-key authentication): ssh user@host cat < mumu However the application hangs waiting for more input. I think this happens because the stdin stream is never closed. How do I do that?

• Turn RSS into array, explode the 'description' and insert words into MySQL table one per row

  - by K.I

  I have only recently gotten into php and MySQL and I want to take an RSS feed, turn it into an array, take only the description part of the XML, explode it and insert it into a table on a MySQL base. I feel like this should be possible, but is a little over my head right now. I tried using magpie as a parser, but if possible I want to do it in simpler php code. The result I am looking for would take a description "This is a cat" and insert it into a table with two fields ID term 1 This 2 is 3 a 4 cat I've been stumped on this for a couple days. Any help would be great.

• Sorting nested hash in ruby

  - by Rabbott

  Provided the following ruby hash: { cat: { 1: 2, 2: 10, 3: 11, 4: 1 }, wings: { 1: 3, 2: 5, 3: 7, 4: 7 }, grimace: { 1: 4, 2: 5, 3: 5, 4: 1 }, stubborn: { 1: 5, 2: 3, 3: 7, 4: 5 } } How can I sort the hash by the sum of 'leaf' excluding "4", for instance the value to compare for "cat" would be (2 + 10 + 11) = 23, the value for "wings" would be (3 + 5 + 7) = 15 so if I was comparing just those two they would be in the correct order, highest sum on top. It is safe to assume that it will ALWAYS be {1: value, 2: value, 3: value, 4: value} as those are keys for constants I have defined. It is also safe to assume that I will only ever want to exclude the key "4", and always use the keys "1", "2", and "3"

• bash: how to know NUM option in grep -A -B "on the fly" ?

  - by Michael Mao

  Hello everyone: I am trying to analyze my agent results from a collection of 20 txt files here. If you wonder about the background info, please go see my page, what I am doing here is just one step. Basically I would like to take only my agent's result out of the messy context, so I've got this command for a single file: cat run15.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' This means : after the regex match, continue forward by 50 lines, stop, then match a line separator starts with "==", go back by 50 lines, if possible (This would certainly clash the very first line). This approach depends on the fact that the hard-coded line number counter 50, would be just fine to get exactly one line separator. And this would not work if I do the following code: cat run*.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' The output would be a mess... My question is: how to make sure grep knows exactly when to stop going forward, and when to stop getting backward? Any suggestion or hint is much appreciated.

• How do I write to a file and print to a terminal cuncurrently in Unix?

  - by bias

  I have a little bash function to log my Macports outputs to a file (since installs often spew little tidbits that are easy to lose in terminal noise), then I just cat the file to the terminal: function porti { command sudo port install $@ >> $1.log 2>&1; cat $1.log } Is there a way to do this concurrently? I don't care about it being in Bash, that's just how I started it. BTW I pass $@ to install but only $1 for the file name so that I can do something like: porti git-gore +bash_completion and only get the file git-core.log however someone else might prefer to include variants in the file name ...

• Why is the base() constructor not necessary?

  - by Earlz

  Hello, I have a class structure like abstract class Animal { public Animal(){ //init stuff.. } } class Cat : Animal { public Cat(bool is_keyboard) : base() //NOTE here { //other init stuff } } Now then, look at the noted line. If you remove : base() then it will compile without an error. Why is this? Is there a way to disable this behavior? I have had multiple bugs now from forgetting the base() which I would have thought to be required on such a special thing as a constructor.

• SQL latest/top items in category

  - by drozzy

  What is a scalable way to select latest 10 items from each category. I have a schema list this: item category updated so I want to select 10 last update items from each category. The current solution I can come up with is to query for categories first and then issue some sort of union query: query = none for cat in categories: query += select top 10 from table where category=cat order by updated I am not sure how efficient this will be for bigger databases (1 million rows). If there is a way to do this in one go - that would be nice. Any help appreciated.

• Persist collection of interface using Hibernate

  - by Olvagor

  I want to persist my litte zoo with Hibernate: @Entity @Table(name = "zoo") public class Zoo { @OneToMany private Set<Animal> animals = new HashSet<Animal>(); } // Just a marker interface public interface Animal { } @Entity @Table(name = "dog") public class Dog implements Animal { // ID and other properties } @Entity @Table(name = "cat") public class Cat implements Animal { // ID and other properties } When I try to persist the zoo, Hibernate complains: Use of @OneToMany or @ManyToMany targeting an unmapped class: blubb.Zoo.animals[blubb.Animal] I know about the targetEntity-property of @OneToMany but that would mean, only Dogs OR Cats can live in my zoo. Is there any way to persist a collection of an interface, which has several implementations, with Hibernate?

• Regular expression for parsing CSV in PHP

  - by Discodancer

  I already managed to split the CSV file using this regex: "/,(?=(?:[^\"]\"[^\"]\")(?![^\"]\"))/" But I ended up with an array of strings that contain the opening and ending double quotes. Now I need a regex that would strip those strings of the delimiter double quotes. As far as I know the CSV format can encapsulate strings in double quotes, and all the double quotes that are already a part of the string are doubled. For example: My "other" cat becomes "My ""other"" cat" What I basically need is a regex that will replace all sequences of N doublequotes with a sequence of (N/2 - rounded down) double quotes. Or is there a better way ? Thanks in advance.

• Find all clauses related to an atom

  - by Luc Touraille

  This is probably a very silly question (I just started learning Prolog a few hours ago), but is it possible to find all the clauses related to an atom? For example, assuming the following knowledge base: cat(tom). animal(X) :- cat(X). , is there a way to obtain every possible information about tom (or at least all the facts that are explicitly stated in the base)? I understand that a query like this is not possible: ?- Pred(tom). so I thought I could write a rule that would deduce the correct information: meta(Object, Predicate) :- Goal =.. [Predicate, Object], call(Goal). so that I could write queries such as ?- meta(tom, Predicate). but this does not work because arguments to call are not sufficiently instantiated. So basically my question is: is this at all possible, or is Prolog not design to provide this kind of information? And if it is not possible, why?

• How to load program reading stdin and taking parameters in gdb?

  I have a program that takes input from stdin and also takes some parameters from command line. It looks like this: cat input.txt myprogram -path "/home/user/work" I try to debug the code with gdb inside emacs, by M-x gdb, I try to load the program with the command: gdb cat input.txt myprogram -path "/home/user/work" However, gdb does not like it. Question cribbed from here. Unfortunately I don't understand the solution and am not sure what to do beyond compiling with the -g option and running the command M-x gdb.

• Can I improve this regex check for valid domain names?

• Symfony2 Entity to array

  - by Adriano Pedro

  I'm trying to migrate my flat php project to Symfony2, but its coming to be very hard. For instance, I have a table of Products specification that have several specifications and are distinguishables by its "cat" attribute in that Extraspecs DB table. Therefore I've created a Entity for that table and want to make an array of just the specifications with "cat" = 0... I supose the code is this one.. right? $typeavailable = $this->getDoctrine() ->getRepository('LabsCatalogBundle:ProductExtraspecsSpecs') ->findBy(array('cat' => '0')); Now how can i put this in an array to work with a form like this?: form = $this ->createFormBuilder($product) ->add('specs', 'choice', array('choices' => $typeavailableArray), 'multiple' => true) Thank you in advance :) # Thank you all.. But now I've came across with another problem.. In fact i'm building a form from an existing object: $form = $this ->createFormBuilder($product) ->add('name', 'text') ->add('genspec', 'choice', array('choices' => array('0' => 'None', '1' => 'General', '2' => 'Specific'))) ->add('isReg', 'choice', array('choices' => array('0' => 'Material', '1' => 'Reagent', '2' => 'Antibody', '3' => 'Growth Factors', '4' => 'Rodents', '5' => 'Lagomorphs'))) So.. in that case my current value is named "extraspecs", so i've added this like: ->add('extraspecs', 'entity', array( 'label' => 'desc', 'empty_value' => ' --- ', 'class' => 'LabsCatalogBundle:ProductExtraspecsSpecs', 'property' => 'specsid', 'query_builder' => function(EntityRepository $er) { return $er ->createQueryBuilder('e'); But "extraspecs" come from a relationship of oneToMany where every product has several extraspecs... Here is the ORM: Labs\CatalogBundle\Entity\Product: type: entity table: orders__regmat id: id: type: integer generator: { strategy: AUTO } fields: name: type: string length: 100 catnumber: type: string scale: 100 brand: type: integer scale: 10 company: type: integer scale: 10 size: type: decimal scale: 10 units: type: integer scale: 10 price: type: decimal scale: 10 reqcert: type: integer scale: 1 isReg: type: integer scale: 1 genspec: type: integer scale: 1 oneToMany: extraspecs: targetEntity: ProductExtraspecs mappedBy: product Labs\CatalogBundle\Entity\ProductExtraspecs: type: entity table: orders__regmat__extraspecs fields: extraspecid: id: true type: integer unsigned: false nullable: false generator: strategy: IDENTITY regmatid: type: integer scale: 11 spec: type: integer scale: 11 attrib: type: string length: 20 value: type: string length: 200 lifecycleCallbacks: { } manyToOne: product: targetEntity: Product inversedBy: extraspecs joinColumn: name: regmatid referencedColumnName: id HOw should I do this?
