  • Why should I use Zend_Application?

    - by Billy ONeal
    I've been working on a Zend Framework application which currently does a bunch of things through Zend Application and a few resource plugins written for it. However, looking at this codebase now, it seems to me that using Zend_Application just makes things more complicated; and a plain, more "traditional" bootstrap file would do a better job of being transparent. This is even more the case because the individual components of Zend -- Zend_Controller, Zend_Navigation, etc. -- don't reference Zend_Application at all. Therefore they do things like "Well just call setRoute and be on your way," and the user is left scratching their head as to how to implement that in terms of the application.ini configuration file. This is not to say that one can't figure out what's going on by doing spelunking through the ZF source code. My problem with that approach is that it's to easy to depend on something that's an implementation detail, rather than a contract, and that all it seems to do is add an extra layer of indirection that one must wade through to understand an application. I look at pre ZF 1.8 example code, before Zend_Application existed, and everywhere I see plain bootstrap files that setup the MVC framework and get on their way. The code is clear and easy to understand, even if it is a bit repetitive. I like the DRY concept that Application gets you, but particularly when I'm assuming first people looking at the app's code aren't really familiar with Zend at all, I'm considering blowing away any dependence I have on Zend_Application and returning to a traditional bootstrap file. Now, my concern here is that I don't have much experience doing this, and I don't want to get rid of Zend_Application if it does something particularly important of which I am unaware, or something of that nature. Is there a really good reason I should keep it around?

  • Numbered list with subclauses

    - by Barry Clearwater
    I'm trying to create a legal document with decimal numbered subclauses, then alpha and roman subsub and subsubsub clauses. (whew!) `1. MAIN HEADING 1.1 This is an example of a sub-clause and you can see that even though the words continue on to the right, it would be best if it wrapped around and formed a block to the right of the decimal number 1.2 In doing so the normal second clause should also wrap around but the second subsequent clause should hang in from the left and be in a block. See below for the remaining clauses (a) this list is completely for demonstration and should not be construed as legal language in any way, nor should make sense in that (b) should the indentation take more than: i) this many lines it would be overly big 11) legal numbering continues in the sub-sub clauses with the use of lower roman lettering and should flow below in a block iii) and continue the formatting on to the next line but be underneath the body of the the text and not begin directly below the number itself. In this example the text carries out to the right but I need it to wrap around underneath. Sorry its so wordy, need this to show the example. 2. Second Clause Heading 2.1 and so it continues thus I've found the examples for decimal numbering but they do not create a block out to the right of the number, and they carry on with multiple decimals rather than alpha and roman sub clauses.

    - by Ola
    I tried to upgrade Ubuntu from 11.10 to 12.04. I left it for 24 hours but the upgrade did not complete. Hence I cancelled the upgrade. I thought I will copy all the files that I have to a DVD/CD and try try downloading a copy of Ubuntu. But now, I cannot open any file or copy them. I cannot even shutdown my laptop. I have many important files on my laptop. Can someone help me retrieve my files from my laptop? Regards Ola

  • Multi screens are not aligning properly

    - by Steve
    I am using (4) Samsung (SMB2230) screens. When I place my mouse on the first screen at the bottom right and pull it into the second screen the mouse jumps to the middle on the left of the second screen. Then it does the same on the 3rd and 4th screens. The biggest jump is between the 1st and 2nd then it tightens up between 2 and 3 then close between 3 and 4. This is a really pain because my mouse gets hung up and I have to move up and down to get it to change screens.I had (4) Dells screens before and this didn't happen. I'm using Windows 7

  • Practical considerations for HTML / CSS naming conventions (syntax)

    - by Jeroen
    Question: what are the practical considerations for the syntax in class and id values? Note that I'm not asking about the semantics, i.e. the actual words that are being used, as for example described in this blogpost. There are a lot of resources on that side of naming conventions already, in fact obscuring my search for practical information on the various syntactical bits: casing, use of interpunction (specifically the - dash), specific characters to use or avoid, etc. To sum up the reasons I'm asking this question: The naming restrictions on id and class don't naturally lead to any conventions The abundance of resources on the semantic side of naming conventions obscure searches on the syntactic considerations I couldn't find any authorative source on this There wasn't any question on SE Programmers yet on this topic :) Some of the conventions I've considered using: UpperCamelCase, mainly as a cross-over habit from server side coding lowerCamelCase, for consistency with JavaScript naming conventions css-style-classes, which is consistent with naming of css properties (but can be annoying when Ctrl+Shift+ArrowKey selection of text) with_under_scores, which I personally haven't seen used much alllowercase, simple to remember but can be hard to read for longer names UPPERCASEFTW, as a great way to annoy your fellow programmers (perhaps combined with option 4 for readability) And probably I've left out some important options or combinations as well. So: what considerations are there for naming conventions, and to which convention do they lead?

  • Plymouth package broken... Can I safely remove it? Other solution to repare it?

    - by Julien Gorenflot
    I have a broken package... So far nothing horrible. The problem is that it is Plymouth, and it seems that if I remove it, I will remove half of the packages of my system... So here is my question: if I actually remove, or even purge plymouth; will I at least have a terminal left after it to reinstall it? Or am I definitely doomed? Just to illustrate what I say; here is the result of an apt-get --reinstall install plymouth: julien@julien-desktop:~$ sudo apt-get --reinstall install plymouth Reading package lists... Done Building dependency tree Reading state information... Done Reinstallation of plymouth is not possible, it cannot be downloaded. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: plymouth : Depends: libdrm-nouveau1 (>= 2.4.11-1ubuntu1~) but it is not installable Recommends: plymouth-themes-all but it is not installable E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). or an apt-get -f install (well basically it is the same) julien@julien-desktop:~$ sudo apt-get -f install [sudo] password for julien: Reading package lists... Done Building dependency tree Reading state information... Done Correcting dependencies... failed. The following packages have unmet dependencies: plymouth : Depends: libdrm-nouveau1 (>= 2.4.11-1ubuntu1~) but it is not installable Recommends: plymouth-themes-all but it is not installable E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. E: Unable to correct dependencies julien@julien-desktop:~$ Any idea would be very welcome...

  • how can I stop my sonicwall TZ-210 (SonicOS Enhanced 5.5.1.0-5o) from responding to arp queries on the wan subnet?

    - by IsaacB
    My sonicwall TZ-210 is answering arp queries on the wan subnet (which my isp doesn't like), basically mapping all the wan ips to its own mac address, causing network havoc since it is not set to route those back to the main isp gateway. How the heck can I turn this behavior off? I have already entered in all wan subnet ips in the static arp cache and left them 'unpublished' which I presumed would mean that it did not bother answering arp queries for them. Apparently it did not do the trick. Arp queries are still being answered unfortunately. What can I do? Any suggestions?

  • Copy Formatting in Word

    - by Ahamad Patan
    Many a times you may need to copy the "Format" in Word. The "Copy Format" feature lets you quickly and easily "copy" all the formatting characteristics from one group of selected text to another. This is helpful when you have several headings that you want consistent formatting. Here are steps on how to Copy Formatting: 1. Select, or highlight, the item of text containing the format you wish to copy. 2. Office 2003 - Click on the Format Painter Button in the Standard Toolbar (looks like Paintbrush). Office 2007 - Format Painter Button is located on the Home tab (looks like a Paintbrush). Office 2003 - An I-beam with a small cross to the left will appear as you move your mouse. Office 2007 - An I-beam with a small paintbrush will appear as you move your mouse. 3. Select the text you wish to copy the formatting to. 4. Formatting of the selected text will automatically change. For multiple formatting changes, double-click on the Format Painter button in Step 2. Remember, you'll have to click it again to deselect it or press Esc.

  • Fixed JavaScript Warning - Pin to Top of Page Using CSS Position [migrated]

    - by nicorellius
    I am new to this site, but it seems like the right place to ask this question. I am working on a noscript chunk of code whereby I do some stuff that includes a <p> at the top of the page that alerts the users that he/she has JavaScript disabled. The end result should look like the Stack Exchange sites when JavaScript is disabled (here is a screenshot of mine - SE looks similar except it is at the very top of the page): I have it working OK, but I would love it if the red bar stayed fixed along the top, upon scrolling. I tried using the position: fixed; method, but it ends up moving the p element and I can't get it to look exactly the same as it does without the position: fixed; modification. I tried fiddling with CSS top and left and other positioning but it doesn't ever look like I want it to. Here is a CSS snippett: <noscript> <style type="text/css"> p. noscript_warning { position: fixed; } </noscript>

  • Are there any good apps for managing vCard vcf files?

    - by Lunatik
    I've just got an Android handset and the import of the SIM contacts from my old phone has left them in a mess; lack of capitalisation, funny character substitutions, odd delimiters etc. I have exported the contacts list as a vcf and while I could manually edit this file, I was really after a desktop app that could do formatting, search & replace etc. There are Android apps that do this but, as much as I like the phone's UI, the prospect of sorting hundreds of contacts via it doesn't exactly fill me with joy. A quick Google just threw up lots of questionable download sites, hoping someone can suggest a lightweight alternative

  • Strange characters appearing on websites - ASCII? - UNICODE?

    - by Mick
    I have created many very simple pure HTML websites over the years. Most of them appear to work fine most of the time. But there is one recurring problem which I have never quite sorted out involving strange characters. The scenario goes like this: I create the site. I look at it in my browser, everything appears fine. I may look at it a great many times over the coming weeks or months as I make additions here and there. Perhaps on a variety of browsers on a variety of PC's. Then one day I look at the page and see a random sprinkling of white question marks against dark diamond shapes. These might appear where I had expected to see hyphens or quotes or apostrophes. My immediate thought is that my browser got into some strange state because I was looking at some foreign website with strange characters, but I'm never quite sure. I'm left with that nagging feeling that perhaps half the planet is seeing my website with funny question marks all over it. So my question is what's going on? What should I do to ensure that as many people as possible around the world can view my text as I originally intended? Should I be using those special html sequences like &pound; for all non alphanumeric characters? Should I worry at all? Edit: Right now I have the problem occurring on this page: http://www.fullreservebanking.com/papers.htm ... part of it looks like this: I am using FireFox 5 and the character encoding currently appears to be "UNICODE (UTF-8)". I do not remember manually setting the character encoding to anything since installation. I do occasionally look at Japanese websites for work related reasons - though when I do so, I do not manually make any changes to firefox settings. Edit: Now fixed. Web page altered accordingly.

  • Libgdx Box2d createfixture crashes vm intermittently

    - by user45021
    I have a hard to debug problem. I have a Box2D game which creates a wheeled vehicle. I want the vehicle body to reflect when it goes from moving left to moving right. to do this i set a flag in a changelistener on a button and then in update method i destroy and recreate the body facing the other way. it works fine most of the time but if i flip the vehicle several times quickly JVM crashes. no errors nothing in log. i added system.out.prints and the errors occur in the routine that instantiates the new body and before anything gets deleted/removed so i don't think the UI is trying to access null pointers. and if it was it should throw an error. M the crash seems to be at createFixture statements. but the work most of the first time. I tried debugging but the error doesn't happen much when the flips are slow. in any case createFixture drops fairly quickly into jni. Is this a Box2D bug? Is GC the issue? From Mission Control I see the GC is collecting on a period of ooh maybe 5s and flipping slower than that mostly works. how do i debug this? i am win7 64bit with 64bit at and jdk7 64bit. libgdx-0.9.9 and sometimes libgdx-nightly-20140215.

  • XNA Required information to represent 2D Sprite graphically

    - by Fire-Dragon-DoL
    I was thinking about dividing my game engine into 2 threads: render thread and update thread (I can't come up on how to divide update thread from physic thread at the moment). That said, I have to duplicate all Sprite informations, what do I really need to represents a 2D Sprite graphically? Here are my ideas (I'll mark with ? things that I'm not sure): Vector2 Position float Rotation ? Vector2 Pivot ? Rectangle TextureRectangle Texture2D Texture Vector2 ImageOrigin ? (is it tracked somewhere else?) If you have any suggestion about using different types for datas, it's appreciated Last part of the question: isn't this a lot of data to copy in a buffer?what should I really copy in the buffer?I'm following this tutorial: http://www.sgtconker.com/2009/11/article-multi-threading-your-xna/3/ Thanks UPDATE 1: Newer values at the moment: Vector2 Position float Rotation Vector2 Pivot Rectangle TextureRectangle Texture2D Texture Color Color byte Facing (can be left or right, I'll do it with an enum) I re-read the tutorial, what I was doing wrong is not that I need to pass all those values, I need to pass only changed values as messages. UPDATE 2: Vector2 Position float Rotation Vector2 Pivot Rectangle TextureRectangle Texture2D Texture Color Color bool Flip uint DrawOrder Vector2 Scale bool Visible ? Mhhh, should Visibile be included?

  • Stereo images rectification and disparity: which algorithms?

    - by alessandro.francesconi
    I'm trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted images plus their depth information by looking at their disparity. Actually I've found lots of papers about these two methods, like: "Computing Rectifying Homographies for Stereo Vision" (Zhang - seems one of the best for rectification only) "Three-step image recti?cation" (Monasse) "Rectification and Disparity" (slideshow by Navab) "A fast area-based stereo matching algorithm" (Di Stefano - seems a bit inaccurate) "Computing Visual Correspondence with Occlusions via Graph Cuts" (Kolmogorov - this one produces a very good disparity map, with also occlusion informations, but is it efficient?) "Dense Disparity Map Estimation Respecting Image Discontinuities" (Alvarez - toooo long for a first review) Anyone could please give me some advices for orienting into this wide topic? What kind of algorithm/method should I treat first, considering that I'll work on a very simple input: a pair of left and right images and nothing else, no more information (some papers are based on additional, pre-taken, calibration infos)? Speaking about working implementations, the only interesting results I've seen so far belongs to this piece of software, but only for automatic rectification, not disparity: http://stereo.jpn.org/eng/stphmkr/index.html I tried the "auto-adjustment" feature and seems really effective. Too bad there is no source code...

  • NCurses, scrolling of multiline items, "current item" pointer and "selected items"

    - by mjf
    I am looking for hints/ideas for the best (most effective) way on how to scroll multi-line items as well as emphasizing of the "current item" and "selected items" such as: 1 FOO ITEM 1 Foo sub-item 2 Foo sub-item 3 Foo sub-item 2 BAR ITEM 1 Bar sub-item 3 BAZ ITEM 1 Baz sub-item 2 Baz sub-item 4 RAB ITEM 5 ZZZ ITEM 1 Zzz sub-item 2 Zzz sub-item 3 Zzz sub-item 4 Zzz sub-item using NCurses (some combination of windows, sub-windows, pads, copywin? Uff! In fact, the lines could exceed the stdscr's width so that possibility to scroll left/right would be also nice - pads?)... The whole items (including the sub-items) are supposed to be emphasized as full-width window/pad areas. The "current item" (including it's set of lines) should be emphasized (i.e. using A_BOLD), selected set of items of choice (including the set of lines for each the selected item) should be emphasized in another way (i.e. using A_REVERSE). What would you choose to cope with it the most effective NCurses way? (The less redrawals/refreshes the better and terminal is supposed to have the ability to change it's size - such as XTerm running under "floating window" management.) Thank you for your ideas (or perhaps some piece of code where something similar is already solved - I was not able to find anything helpful on the Internet. I mean I am not going to copy/paste foreign code but programming NCurses properly is still somehow difficult to me). P.S.: Would you suggest to "smooth-scroll" +1/-1 screen line or rather "jump-scroll" +lines/-lines of the items? (I personally prefer the latter one.) Sincerely, -- mjf

  • Macbook Pro keyboard with BootCamp - missing the Home/End/PageUp/PageDown keys

    - by brainjam
    Last year I converted from Windows to a MacBook Pro and went through the process of learning the ways of the Mac keyboard. In particular, I learned that Ctrl-left and Ctrl-right were the Mac way of doing Home and End. I'm now doing a project on Windows 7 on Bootcamp, and finding that I'm missing the Windows Home and End keys in a completely different way -- they don't exist, but the Mac combos don't work either. Any suggestions for getting this functionality somehow? Code editing is a real drag without these keys.

  • My Intel Core i3 frequently shuts down due to "Processor Thermal Trip error"

    - by explorest
    My Desktop PC running Windows 7 on Intel Core i3 dual processor machine started shutting down during the boot process a couple of days ago. I left it alone for about 48 hours and tried again. The boot process informed me about Processor Thermal Trip as being the cause of boot failures and suggested a Windows recovery process. I went through the recovery process which completed without problems. The PC booted normally and Windows 7 worked as expected but after 10 minutes it again tripped and now whenever I start it, it shuts down during the boot process. What should I do next?... is there a boot menu / setup settings that needs to be adjusted to avoid it... Or is there a hardware problem (which seems unlikely as the machine occasionally boots perfectly )?

  • Natively boot Virtualbox Image

    - by isync
    I am faced with a Windows hardware/software problem left over from another person. It's on me to resolve. It's a mission critical setup. The situation is: I've got a physical server machine with: -Disk C:\ (one disk) containing a basic install of Windows Server 2008 R2, formerly Win Vista Pro, now gone. -Disk D:\ (software Raid) containing a VirtualBox disk image of a configured Windows Server 2008 R2 running SQL Server R2 among others. What shall I do now? Migrate all the stuff from the configured VM to the basic but natively installed C:\ Windows Server 2008 R2 (with the possibility of breaking stuff)? Or, Setting up the machine to "natively boot" the VM with the help of bcdedit.exe (something I've read about, what I've never done, what I don't know of if it works, if it hits performance, or if it is stable for production) For me, being old skool, I am in the process of de-virtualising everything (option 1). But I'd be happy if someone suggests I am ok to go down the "natively boot" route.

  • Perl - can't flush STDOUT or STDERR

    - by Jim Salter
    Perl 5.14 from stock Ubuntu Precise repos. Trying to write a simple wrapper to monitor progress on copying from one stream to another: use IO::Handle; while ($bufsize = read (SOURCE, $buffer, 1048576)) { STDERR->printflush ("Transferred $xferred of $sendsize bytes\n"); $xferred += $bufsize; print TARGET $buffer; } This does not perform as expected (writing a line each time the 1M buffer is read). I end up seeing the first line (with a blank value of $xferred), and then the 7th and 8th lines (on an 8MB transfer). Been pounding my brains out on this for hours - I've read the perldocs, I've read the classic "Suffering from Buffering" article, I've tried everything from select and $|++ to IO::Handle to binmode (STDERR, "::unix") to you name it. I've also tried flushing TARGET with each line using IO::Handle (TARGET-flush). No dice. Has anybody else ever encountered this? I don't have any ideas left. Sleeping one second "fixes" the problem, but obviously I don't want to sleep a second every time I read a buffer just so my progress will output on the screen! FWIW, the problem is exactly the same whether I'm outputting to STDERR or STDOUT.

  • Ubuntu 12.10 + Windows 7 - No option to install alongside windows 7

    - by user1828314
    I have a 64-bit Windows 7 OS installed at the moment. I have used GPartEd to shrink the current Windows 7 partition on my 720GB HDD to 200GB. I have then made a new NTFS partition of 200GB which I will keep for later on as a shared drive between both Windows 7 and Ubuntu. So in GPartEd I now have 3 partitions which were all automatically there from the Windows 7 installation, I only shrank the 3rd one from the 698GB or so that it was to 200GB and created the 200GB for the shared drive. I first tried creating another 200GB partition at this stage to install Ubuntu too but when I burnt the DVD and loaded it, Ubuntu gave me no option to install alongside Windows, only the option to erase the entire disk and install Ubuntu on the blank drive...not what I want to do. So I tried installing it through clicking 'Something else', it downloaded all the install files but didn't install. I then had a lot of problems with getting the DVD drive to work and what not but now have this fixed so I can use Windows again. So now I've used GPartEd to delete the partitions so again I'm now left with the 3 partitions there which Windows 7 automatically installs and a 200GB NTFS partition I will later use as a shared drive. Booting up from the Ubuntu disc and again there is no option to install alongside Windows 7. How do I get it to do so? All I would like is Windows 7 and Ubuntu on a dual boot, with a 200GB NTFS partition to dump my work onto so that I can access it from both OS's. Thanks.

I have tried various combinations of apt-get options to no success. apt-get remove apache2 apt-get remove --purge apache2 apt-get purge apache2 apt-get autoremove apache2 None of these totally remove apache properly. Nothing works, the /etc/apache2 directory still exists. So I deleted it. When I install apache the folder is never created. Running Ubuntu server 10.10.

  • Updating from OSX Lion 10.7.2 to 10.7.4

    - by Ozair Kafray
    I just got my Mac upgraded to 10.7.2, just to be able to install Xcode 4.3.3. However, when I try to install Xcode 4.3.3, it says that it requires a minimum of OSX 10.7.3. Then using the "Software Upgrade" tool it detects successfully for me that a combined upgrade to 10.7.4 is available. As I select Install Item, the download starts however, it fails after complete download (taking two hours) saying something like "the update cannot be saved". I have done this twice already, and followed it up until 5 minutes were left. I have also checked that there is enough space (60 GB) available on my hard disk, while the update requires around 1.5 GB. The question is what is causing the problem mentioned in bold above.

  • SQL Bits X – Temporal Snapshot Fact Table Session Slide & Demos

    - by Davide Mauri
    Already 10 days has passed since SQL Bits X in London. I really enjoyed it! Those kind of events are great not only for the content but also to meet friends that – due to distance – is not possible to meet every day. Friends from PASS, SQL CAT, Microsoft, MVP and so on all in one place, drinking beers, whisky and having fun. A perfect mixture for a great learning and sharing experience! I’ve also enjoyed a lot delivering my session on Temporal Snapshot Fact Tables. Given that the subject is very specific I was not expecting a lot of attendees….but I was totally wrong! It seems that the problem of handling daily snapshot of data is more common than what I expected. I’ve also already had feedback from several attendees that applied the explained technique to their existing solution with success. This is just what a speaker in such conference wish to hear! :) If you want to take a look at the slides and the demos, you can find them on SkyDrive: https://skydrive.live.com/redir.aspx?cid=377ea1391487af21&resid=377EA1391487AF21!1151&parid=root The demo is available both for SQL Sever 2008 and for SQL Server 2012. With this last version, you can also simplify the ETL process using the new LEAD analytic function. (This is not done in the demo, I’ve left this option as a little exercise for you :) )
