• Suggestions for debugging print stylesheets?

  - by Jim Puls

  I've recently been working on a print stylesheet for a website, and I realized that I was at a loss for effective ways to tweak it. It's one thing to have a reload cycle for working on the on-screen layout: change code command-tab reload but that whole process gets much more arduous when you're trying to print: change code command-tab reload print squint at print-preview image open PDF in Preview for further inspection Are there tools I'm missing out on here? Does WebKit's inspector have a "pretend this is paged media" checkbox? Is there some magic that Firebug (shudder) can do?

• Lombok with Play 2

  - by Alex Povar

  What about Lombok integration with Play Framework 2? I really like Lombok it make my code more readable and less boilerplate. And Play Framework is wonderful too. But there is a great trouble in case if you going to mixup them. Main reason is that scala temlates in play project compiled before domain classes. So Lombok, which itself is compiler's hack do not generate accessors for that time. The question is: if it any ways to make it work? I found some discussions in Google Groups, but they do not provide any reasonable solution. So have you got any success with it? And.. why guys from Play Framework project do not provide some Lombok-like solution? Anyway Play is full of code-generation magic and shadow compiling... so, why not?

• Should one use < or <= in a for loop

  - by Eugene Katz

  If you had to iterate through a loop 7 times, would you use: for (int i = 0; i < 7; i++) or: for (int i = 0; i <= 6; i++) There are two considerations: performance readability For performance I'm assuming Java or C#. Does it matter if "less than" or "less than or equal to" is used? If you have insight for a different language, please indicate which. For readability I'm assuming 0-based arrays. UPD: My mention of 0-based arrays may have confused things. I'm not talking about iterating through array elements. Just a general loop. There is a good point below about using a constant to which would explain what this magic number is. So if I had "int NUMBER_OF_THINGS = 7" then "i <= NUMBER_OF_THINGS - 1" would look weird, wouldn't it.

• findManyToManyRowset with Zend_Db_Table_Select

  - by Typeoneerror

  Hello. I'm trying to use a select object to filter the results of a many to many rowset. This call works great: $articles = $this->model->findArticlesViaArticlesUsers(); This however does not: $articles = new Default_Model_Articles(); $articleSelect = $articles->select(); $articleSelect->where("status = 'published'") ->order("date_published DESC") ->limit(1); $articles = $this->model->findArticlesViaArticlesUsers($articleSelect); That throws the following error: exception 'Zend_Db_Select_Exception' with message 'You cannot define a correlation name 'i' more than once' I can't figure out how to successfully get "articles that have the status of 'published'" using the magic many-to-many relationship (nor findManyToManyRowset). I'm at the end of my rope and thinking of just writing the sql manually. Any ideas?

• No Flash, How do i handle jcupload ?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• Lost in UTF-8 hell. (Django and Python)

  - by user140314

  I am working through the Django RSS reader project here. The RSS feed will read something like "OKLAHOMA CITY (AP) — James Harden let". The RSS feed's encoding reads encoding="UTF-8" so I believe I am passing utf-8 to markdown in the code snippet below. The em dash is where it chokes. I get the Django error of "'ascii' codec can't encode character u'\u2014' in position 109: ordinal not in range(128)" which is an UnicodeEncodeError. In the variables being passed I see "OKLAHOMA CITY (AP) \u2014 James Harden". The code line that is not working is: content = content.encode(parsed_feed.encoding, "xmlcharrefreplace") I am using markdown 2.0, django 1.1, and python 2.4. What is the magic sequence of encoding and decoding that I need to do to make this work? Thanks.

• Mapping functions of 2D numpy arrays

  - by perimosocordiae

  I have a function foo that takes a NxM numpy array as an argument and returns a scalar value. I have a AxNxM numpy array data, over which I'd like to map foo to give me a resultant numpy array of length A. Curently, I'm doing this: result = numpy.array([foo(x) for x in data]) It works, but it seems like I'm not taking advantage of the numpy magic (and speed). Is there a better way? I've looked at numpy.vectorize, and numpy.apply_along_axis, but neither works for a function of 2D arrays. EDIT: I'm doing boosted regression on 24x24 image patches, so my AxNxM is something like 1000x24x24. What I called foo above applies a Haar-like feature to a patch (so, not terribly computationally intensive).

• Software mirroring (RAID1) versus "Fake Raid" for new Windows 7 install

  - by kquinn

  I've just ordered two new hard drives for my main desktop and a copy of Windows 7 Professional 64-bit. I'd like to do a clean install of Win7 onto the new drives (leaving my old XP Pro boot partition around for a while in case something goes disastrously wrong, etc.). I want to have them set up in mirrored (RAID-1) mode. My understanding is that Win7 Pro can do software mirroring, but can I set this up directly at install time? If so, how? Note that I'd like the disk to be split into three partitions (OS/Apps&Data/Bulk data), all of which should be mirrored. Would it be better (more reliable or faster) to use my motherboard's hardware RAID support? My motherboard is an older nVidia nForce 680i SLI, which is not the most stable of motherboards, and I'm not sure how trustworthy its RAID1 configuration might be (or if Win7 could even detect and install onto a hardware-mirrored volume). Also, the performance characteristics of RAID1 are rather different than RAID0 or RAID5, and I'm wondering if Win7's software mirroring might actually be faster than hardware RAID1 (for example, I'm more of a Unix admin when I have to wear the sysadmin hat, and I've had great success deploying ZFS; most hardware RAID1 implementations have to read both disks and compare results to look for data errors, but ZFS can read from only one disk in the mirror and just use the built-in checksum, meaning it can have up to 2x the number of reads in-flight, as long as there's no data corruption). Edit: Okay, my question about whether Windows 7 can do software mirroring has been answered, and it can. I'm still unsure whether Windows software RAID or my motherboard's hardware "fake RAID" function is a better choice, though. Remember, I'm only interested in mirroring -- not the more complicated striping or parity operations that generally show the poor performance of crappy motherboard RAID solutions.

• Is it possible to "merge" the values of multiple records into a single field without using a stored

  - by j0rd4n

  A co-worker posed this question to me, and I told them, "No, you'll need to write a sproc for that". But I thought I'd give them a chance and put this out to the community. Essentially, they have a table with keys mapping to multiple values. For a report, they want to aggregate on the key and "mash" all of the values into a single field. Here's a visual: --- ------- Key Value --- ------- 1 A 1 B 1 C 2 X 2 Y The result would be as follows: --- ------- Key Value --- ------- 1 A,B,C 2 X,Y They need this in SQLServer 2005. Again, I think they need to write a stored procedure, but if anyone knows a magic out-of-the-box function that does this, I'd be impressed.

• How do I get developers to treat test code as "real" code?

  - by womp

  In the last two companies I've been at, there is an overriding mentality among developers that it's okay to write unit tests in a throw-away style. Code that they would never write in the actual product suddenly becomes OK in the unit tests. I'm talking Rampant copying and pasting between tests Code styling rules not followed Hard-coded magic strings across tests No object-oriented thought or design for integration tests, mocks or helper objects (250 line single-function tests!) .. and so on. I'm highly dissatisfied with the quality of the test code. Generally we do not do code reviews on our test assemblies, and we also do not enforce style or code analysis of them on our build server. Is that the only way to overcome this inertia about test quality? I'm looking for ideas to take to our developers, without having to go to higher management saying that we need to use resources for enforcement of test quality (although I will if I have to). Any thoughts or similar experiences?

• EF Code First - Include(x => x.Properties.Entity) a 1 : Many association

  - by VulgarBinary

  Given a EF-Code First CTP5 entity layout like: public class Person { ... } which has a collection of: public class Address { ... } which has a single association of: public class Mailbox { ... } I want to do: PersonQuery.Include(x => x.Addresses).Include("Addresses.Mailbox") WITHOUT using a magic string. I want to do it using a lambda expression. I am aware what I typed above will compile and will bring back all Persons matching the search criteria with their addresses and each addresses' mailbox eager loaded, but it's in a string which irritates me. How do I do it without a string? Thanks Stack!

• CSS3PIE: Internet Explorer 6 doesn't download PIE.htc

  - by Jonas

  I'm using the very impressive CSS3PIE (http://css3pie.com) library to add support for CSS3 styles in IE6-8. It works fine in versions 7 and 8 and took a lot of pain out of the process. However, in IE6 no CSS3 styles are shown at all. In fact, looking at the server logs, I can see that IE6 doesn't even download the PIE.htc file, which is necessary for the magic to work. The content type for the file is set correctly as text/x-component, it's referenced by absolute URL, and works fine in IE7 and 8. I'm using Compass (www.compass-style.org) and the PIE helper which makes the CSS look like this: #shopping_cart { behavior: url("/media/static/css/PIE.htc"); position: relative; border-radius: 10px; } I can't figure out what the problem is. Does anyone have any ideas what might cause IE6 to skip the behavior definition altogether? Cheers, Jonas

• What to name this class?

  - by orlandu63

  (This is not an interface: I simply omitted the method bodies) class _ { protected $_data = array(); function __construct($data); function set($name, $value); function get($name); function __set($name, $value); function __get($name); //aliases for their respective non-magic methods. # and some other generic methods } Essentially it's a class that provides a magical object-oriented reusable access layer to some data. I've considered DataLayer, DataObject and some others; I'd like to hear some suggestions from someone who's more terminologically savvy.

• SQL Server version of MySQL's group_concat and escaped strings

  - by TheObserver

  I only have the Express versions of MS SQL Server 2008 and Visual Studio. Given that I can't create a SQL Server project and therefore CLR solutions are out of the question, I've attempted to use select col1, stuff( ( select ' ' + col2 from StrConcat t1 where t2.col1 = t1.col1 for xml path('') ),1,1,'') from StrConcat t2 group by col1 order by col1 to get a row concatenated col2. col2 is a varchar field with some control characters like & and \n. When it is concatenated with the above SQL, it appears to escape those control characters ie. & becomes & amp ; and \n becomes &#xOD, which is not what I want it to do. So, the question is, what black box magic is causing that to happen?

• Optimal file system type and mount options for an rsnapshot dedicated drive

  - by Nimmy Lebby

  We have an external USB 2 drive that we are using as a backup drive for our configuration. We use rsnapshot for the backups. It uses a few standard commands for managing snapshots: rm -rf: deletes expired snapshots mv: moves older snapshots down a slot cp -al: duplicates last snapshot to new slot rsync -a --delete --numeric-ids --relative: synchronizes new snapshot As you could see by the log below, the majority of the time is spent on the rm -rf and the cp -al steps: [25/Dec/2010:14:00:02] rsnapshot hourly: started [25/Dec/2010:14:00:02] echo 21012 > /var/run/rsnapshot.pid [25/Dec/2010:14:00:02] rm -rf /mnt/extdrive/snapshots/hourly.5/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.4/ /mnt/extdrive/snapshots/hourly.5/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.3/ /mnt/extdrive/snapshots/hourly.4/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.2/ /mnt/extdrive/snapshots/hourly.3/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.1/ /mnt/extdrive/snapshots/hourly.2/ [25/Dec/2010:14:15:48] cp -al /mnt/extdrive/snapshots/hourly.0 /mnt/extdrive/snapshots/hourly.1 [25/Dec/2010:14:23:32] rsync -a --delete --numeric-ids --relative /etc /mnt/extdrive/snapshots/hourly.0/sm4/ [25/Dec/2010:14:23:52] touch /mnt/extdrive/snapshots/hourly.0/ [25/Dec/2010:14:23:52] rm -f /var/run/rsnapshot.pid [25/Dec/2010:14:23:52] rsnapshot hourly: completed successfully My questions: I'm currently using ext4 for the filesystem. Maybe this is not the best choice from those available in Red Hat. Anyone have any recommendations that would speed up the process? The partition's mount options are sync,dirsync 1 2. Is there a way to optimize this since it's solely used for rsnapshot? Of course, reasoning would be greatly appreciated.

• Cannot connect to *.dbf file through JDBC drivers

  i'm trying to connect to *.dbf (dBase III) file on my Java application, running on a Windows Server 2003 system.

• Regular Expressions: RegEx for determining valid PHP class property names?

  - by Brian Lacy

  I am using PHP's magic __set and __get methods to access a private array in a class. I want to make sure the property names requested (i.e. $myObj->FakeProperty) are valid according to PHP property name rules before accessing them. My current RegEx isn't doing the trick; with my test values, _12 always falls through the cracks. I'm not actually sure that my test values even represent a realistic representation of what is and isn't allowed for PHP class property names, but I'm not really too concerned about it, just that I have some sort of rudimentary check in place. Test Fields: albert12 12Albert _12 _Albert12 _12Albert _____a_1 RegEx: ^(?=_*[A-z]+)[A-z0-9_]+$

• XSD NewDataSet Namespace?

  - by Ian

  I'm running XSD on an XML file and getting something strange. Depending on the depth of elements it produces a 'NewDataSet' element which will then is prefixed in Visual Studio to my auto-generated classes which is something I don't want. I've got quite a complex structure and am just trying to add a simple version element or attribute which is causing the problem. The simplest demo I could come up with is this. <A> <B>Text</B> </A> Running this through XSD says there is an element called 'NewDataSet' which may or may not appear and will prefix namespaces. <A> <B> <C>Text</C> </B> </A> This example works as expected and there is no magic 'NewDataSet' element in the generated XSD file.

• Is there an equivalence to CDOSYS AutoGenerateTextBody in .NET

  - by AnthonyWJones

  I'm porting some VBScript code which generates emails using the standard CDOSYS Message object. The Message oject has a property AutoGenerateTextBody which when true will cause it to automatically create the TextBody property value when you assign HTML to the HTMLBody property. Hence creating the typical text/plain and text/html alternatives in the message body. However .NET appears to be missing this function. The MailMessage object does have the ability to create alternative views but there doesn't appear to be a way to easily create the text body content from the HTML content. I'm not necessarily looking for an auto-magic option but I do need a solution to taking what is an HTML string and converting it to a reasonable plain text representation. Just dropping all the HTML markup doesn't cut it. Is there a tool buried somewhere in the existing .NET framework that can do this?

• Multi-part gzip file random access (in Java)

  - by toluju

  This may fall in the realm of "not really feasible" or "not really worth the effort" but here goes. I'm trying to randomly access records stored inside a multi-part gzip file. Specifically, the files I'm interested in are compressed Heretrix Arc files. (In case you aren't familiar with multi-part gzip files, the gzip spec allows multiple gzip streams to be concatenated in a single gzip file. They do not share any dictionary information, it is simple binary appending.) I'm thinking it should be possible to do this by seeking to a certain offset within the file, then scan for the gzip magic header bytes (i.e. 0x1f8b, as per the RFC), and attempt to read the gzip stream from the following bytes. The problem with this approach is that those same bytes can appear inside the actual data as well, so seeking for those bytes can lead to an invalid position to start reading a gzip stream from. Is there a better way to handle random access, given that the record offsets aren't known a priori?

• Scanning website for vulnerablities

  - by Kristen

  I have found that the local school's website installed a Perl Calendar - this was years ago, it has not been used for ages, but Google has it indexed (which is how I found it) and it full of Viagra links and the like ... program was by Matt Kruse, here is details of the exploit: http://www.securiteam.com/exploits/5IP040A1QI.html I've got the school to remove that, but I think they also have MySQL installed and I'm aware that out-of-the-box there have been some exploits of Admin Tools / Login in old versions. For all I know they also have PHPBB and the like installed ... The school is just using some cheap, shared hosting; the HTTP response header I get is: Apache/1.3.29 (Unix) (Red-Hat/Linux) Chili!Soft-ASP/3.6.2 mod_ssl/2.8.14 OpenSSL/0.9.6b PHP/4.4.9 FrontPage/5.0.2.2510 I'm looking for some means of checking if they have other junk installed (quite possibly from way back, and now unused) that might put the site at risk. I'm more interested in something that can scan for things like the MySQL Admin exploit rather than open ports etc. My guess is that they have little control over the hosting space that they have - but I'm a Windows DEV, so this *nix stuff is all Greek to me. I found http://www.beyondsecurity.com/ which looks like it might do what I want (within their evaluation :) ) but I have a worry about how to find out if they are well known / honest - otherwise I will be tipping them a wink with a Domain Name that may be at risk! Many thanks.
