  • Graduating soon with a computer science degree, but have unique circumstances [closed]

    - by Donnie
    I joined the Navy in 1998, and was admitted into Nuclear Power Training. I got my electrician's mate certificate, but was put on medical hold when I was in Nuclear Power Training. I was sent to the Naval Hospital, and received a medical (honorable) discharge in the middle of 2000. I decided to stay at home and raise my son, and my girlfriend worked. a few years ago, I decided that I want to work as a programmer, so I went to college and will soon be graduating with a degree in computer science. I hope to finish with a relatively high GPA, 3.8 or 3.9. My question is this: How much, if any, of my Navy experience should I put on my resume? And how do I explain my nine year gap as a stay at home dad? Do I even try to explain it? I know recent college graduates typically have no experience, but obviously I'm not the typical college graduate. Will my long absence from working, or my relatively short duration in the Navy hurt my chances? Should I just put the college on my resume, and hope that HR thinks I'm younger than I am? Obviously, then, my age would show at the interview and there would be questions. Any help is appreciated.

  • Designs for outputting to a spreadsheet

    - by Austin Moore
    I'm working on a project where we are tasked to gather and output various data to a spreadsheet. We are having tons of problems with the file that holds the code to write the spreadsheet. The cell that the data belongs to is hardcoded, so anytime you need to add anything to the middle of the spreadsheet, you have to increment the location for all the fields after that in the code. There are random blank rows, to add padding between sections, and subsections within the sections, so there's no real pattern that we can replicate. Essentially, anytime we have to add or change anything to the spreadsheet it requires a many long and tedious hours. The code is all in this one large file, hacked together overtime in Perl. I've come up with a few OO solutions, but I'm not too familiar with OO programming in Perl and all my attempts at it haven't been great, so I've shied away from it so far. I've suggested we handle this section of the program with a more OO friendly language, but we can't apparently. I've also suggested that we scrap the entire spreadsheet idea, and just move to a webpage, but we can't do that either. We've been working on this project for a few months, and every time we have to change that file, we all dread it. I'm thinking it's time to start some refactoring. However, I don't even know what could make this file easier to work with. The way the output is formatted makes it so that it has to be somewhat hardcoded. I'm wondering if anyone has insight on any design patterns or techniques they have used to tackle a similar problem. I'm open to any ideas. Perl specific answers are welcome, but I am also interested in language-agnostic solutions.

  • How do I position a 2D camera in OpenGL?

    - by Elfayer
    I can't understand how the camera is working. It's a 2D game, so I'm displaying a game map from (0, 0, 0) to (mapSizeX, 0, mapSizeY). I'm initializing the camera as follow : Camera::Camera(void) : position_(0.0f, 0.0f, 0.0f), rotation_(0.0f, 0.0f, -1.0f) {} void Camera::initialize(void) { glMatrixMode(GL_PROJECTION); glLoadIdentity(); glTranslatef(position_.x, position_.y, position_.z); gluPerspective(70.0f, 800.0f/600.0f, 1.0f, 10000.0f); gluLookAt(0.0f, 6000.0f, 0.0f, 0.0f, 0.0f, -1.0f, 0.0f, 1.0f, 0.0f); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); glEnable(GL_DEPTH_TEST); glDepthFunc(GL_LEQUAL); } So the camera is looking down. I currently see the up right border of the map in the center of my window and the map expand to the down left border of my window. I would like to center the map. The logical thing to do should be to move the camera to eyeX = mapSizeX / 2 and the same for z. My map has 10 x 10 cases with CASE = 400, so I should have : gluLookAt((10 / 2) * CASE /* = 2000 */, 6000.0f, (10 / 2) * CASE /* = 2000 */, 0.0f, 0.0f, -1.0f, 0.0f, 1.0f, 0.0f); But that doesn't move the camera, but seems to rotate it. Am I doing something wrong? EDIT : I tried that: gluLookAt(2000.0f, 6000.0f, 0.0f, 2000.0f, 0.0f, -1.0f, 0.0f, 1.0f, 0.0f); Which correctly moves the map in the middle of the window in width. But I can't move if correctly in height. It always returns the axis Z. When I go up, It goes down and the same for right and left. I don't see the map anymore when I do : gluLookAt(2000.0f, 6000.0f, 2000.0f, 2000.0f, 0.0f, 2000.0f, 0.0f, 1.0f, 0.0f);

  • Getting started on Large Projects

    - by Mercfh
    So I just graduated from my College with a B.S. in Comp. Science (although it was a good school, we're the only accredited CS department in our state.....for w/e that means lol) I feel like im a decent programmer, not amazing....but not terrible. Anyways I got my first job about 2 weeks ago, it's a pretty entry level job: firmware development/tester (I know I know people look down on testers...but I gotta start somewhere). Anyways there isn't a whole lot of coding to be had right now (mostly simple stuff) but here soon I have the option of helping out with development (which is what I want to do) Thing is....I have NEVER worked on a huge project. I mean in school sure we had "group" projects but nothing really big. So I'm not super familiar with HUGE classes and such (main language was C++)....Is this something I'll just get used to with time? Some fellow students were used to that with internships and such...but I never got that chance. My job was mostly a "one man job" kinda thing. Mostly little things. Plus in class we never did huge projects anyways. So how do you guys I guess "plan" out these things? Do you use a whiteboard and plan out classes and such....or what. Also...another worry of mine is that I have to use google......ALOT for examples of code, because sometimes I just don't get how something works. Is this normal? It makes me feel sorta.....stupid I guess. I mean "technically" i've had 4-5 years coding experience......but it really only feels like I had 2 years of REAL experience. If that makes any sense? Thanks

  • Tipps & Tricks rund um CRSCTL

    - by Sebastian Solbach (DBA Community)
    Egal ob Single Instanz oder für Real Applikation Cluster Datenbanken die Grid Infrastruktur findet man bei immer mehr Systemen im Einsatz. Das liegt sowohl an der vereinfachten Überwachungstätigkeiten für die Oracle Datenbank, Listener und ASM Instanz, als auch an einigen weiterführenden Features, wie der einfachen Service Verwaltung für Single Instanz, DataGuard und/oder RAC. Dabei kommen insbesondere den Cluster Ready Services (CRS), einem Bestandteil der Clusterware Komponente der Grid Infrastruktur, eine wichtige Bedeutung zu, da diese intern alle Ressourcen steuert. Ressourcen können hierbei natürlich nicht nur die Oracle Prozesse (Datenbank, Listener, Virtuelle IP Adressen etc.) sein, sondern auch eigene Applikationen, die unter die Überwachung der Grid Infrastruktur resp. Clusterware gestellt werden. Dies kann von simplen Neustartanforderungen im Single Server Betrieb bis zu klassischen Failover Szenarien in Clusterumgebungen reichen. Diesem Aspekt trägt auch die Tatsache Rechnung, dass es seit einiger Zeit generische Applikations-Agenten (Siebel, Tomcat, GoldenGate, Apache, ...) für die Clusterware gibt und eine abgespeckte GI Installation auf der Oracle eigenen Middleware Hardware (Exalogic) läuft, um die Prozesse zu überwachen. Diese Cluster Ready Services werden vom Befehl "crsctl" gesteuert. Deshalb lohnt es sich dieses Utility mal genauer anzuschauen, zumal es einige Feinheiten enthält, die nicht direkt aus der Dokumentation bzw. Hilfe des Tools ersichtlich sind.

  • How can I properly create /dev/dvd?

    - by chazomaticus
    Certain programs look for /dev/dvd by default to find DVDs. When I first boot my computer without a DVD inserted, /dev/dvd exists and points to the correct place (/dev/sr0). However, when I insert a DVD, /dev/dvd disappears. I'd like it to stick around so I don't have to navigate to /dev/sr0 in programs that are looking for DVDs. How do I ensure that the /dev/dvd symlink exists and points to the right place? It looks like I can add something to /etc/udev/rules.d/70-persistent-cd.rules. This site gives a couple of examples, but the 70-persistent-cd.rules file says "add the ENV{GENERATED}=1 flag to your own rules", which isn't part of the examples. The man 7 udev page is impenetrable to me, and I'm not convinced the linked page gives 100% of the information I need. So, what can I do on a modern, Ubuntu 12.04 (or later) system to make /dev/dvd always exist and point to the right device? EDIT: Is it as simple as adding ENV{GENERATED}=1 to the rules in the linked page, something like this: SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="dvd", GROUP="cdrom", ENV{GENERATED}=1 Is that the right information for modern Ubuntu? What is ENV{GENERATED} doing there, when it wasn't generated, but hand-written?

  • Basic is Best

    - by Eric A. Stephens
    Fellow foodies will recognize the recent movement towards "farm-to-table" restaurants. These venues attempt to simplify their menus and source ingredients as close to the source as possible. I had the opportunity to dine at such a restaurant the other evening. I was gushing about the appetizer to my server when she described the preparation for the item and then punctuated her comments with "basic is best". I reminded my fellow enterprise architect diners there was an architecture lesson in that statement. They rolled their eyes and chuckled. But they also knew I was right. I'm reminded of Frederick Brooks' book The Mythical Man Month and his latest The Design of Design. The former must read book talks about complexity. But he refrains from damning all complexity. The world we live in and enterprises we strive to transform with enterprise architecture are complicated organisms, much like the human body. But sometimes a simple solution is the best approach. Fewer applications (think: portfolio rationalization). Fewer components. Fewer lines of code. Whatever level of abstraction you are working at, less is more. I'm reminded of the enterprise architecture principle "Control Technical Diversity". At one firm I created pithy catch phrases for each principles. I named this one "Less is More". But perhaps another variation is what my server said the other night, "Basic is Best".

  • Problem with missing JSON functions on PHP 5.2.6 / Plesk 8.4

    - by Drachenviech
    I have a vserver running openSuse 10.3, Apache 2 and Plesk 8.4. I can update/upgrade neither, as it is apparently not recommended to upgrade openSuse 10.3 (and an update to the EOL 10.4 does not seem to make much sense) and Plesk fails to update no matter what version I try (even fails to upgrade to 8.4.1). Still I can live with that somehow, primarily because I don’t have the time to do a fresh remote install on the vserver. What really is a problem is, that though the installed PHP is 5.2.6 it has no zip library and no json functions. The first is probably because PHP was not compiled with --enable-zip. The second is a big mystery though. As I understand it, it always comes with PHP unless its compiled with the --disable-json configure option. This is however not the case. And the json extension module is just not there. I even tried to enable it with extension=json.so with no luck either. the configure options of my PHP are (as shipped with Plesk 8.4) '../configure' '--prefix=/usr' '--datadir=/usr/share/php5' '--mandir=/usr/share/man' '--bindir=/usr/bin' '--with-libdir=lib' '--includedir=/usr/include' '--sysconfdir=/etc/php5/apache2' '--with-config-file-path=/etc/php5/apache2' '--with-config-file-scan-dir=/etc/php5/conf.d' '--enable-libxml' '--enable-session' '--with-mm' '--with-pcre-regex=/usr' '--enable-xml' '--enable-simplexml' '--enable-spl' '--enable-filter' '--disable-debug' '--enable-inline-optimization' '--disable-rpath' '--disable-static' '--enable-shared' '--program-suffix=5' '--with-pic' '--with-gnu-ld' '--with-system-tzdata=/usr/share/zoneinfo' '--with-apxs2=/usr/sbin/apxs2' '--disable-all' '--disable-cli' As I understand it, PECL is not an option with 5.2.6. Or am I mistaken? Even if I was not, the openSuse repository only goes as far as PHP 5.2.4. The openSuse install even came without zypper, which I had to manually install. So is there a way to get ziplib and json running in PHP 5.2.6 without having to recompile the binary?

  • Coordinate and positioning problem on iOS with cocos2d-x

    - by Vexille
    I'm using cocos2d-x alongside with Marmalade and running some tests and tutorials before starting an actual project with them. So far things are working reasonably well on the windows simulator, Android and even on Blackberry's Playbook, but on iOS devices (iPhone and iPad) the positioning seems to be off. To make things clearer, I put together a scene that just draws an image in the middle of the screen. It worked as expected on everything else, but this is the result I got on an iPhone: To get the coordinates for the center of the screen I'm using the VisibleRect class from the TestCpp sample. It just uses sharedOpenGLView to get the visible size and visible origin, and calculate the center from that. CCSprite* test = CCSprite::create("Ball.png", CCRectMake(0, 0, 80, 80) ); test->setPosition( ccp(VisibleRect::center().x, VisibleRect::center().y) ); this->addChild(test); Also I have a noBorder policy set on AppDelegate: CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width, designSize.height, kResolutionNoBorder); One funny thing is that I tried to deploy the TestCpp sample project to some iOS devices and it worked reasonably well on the iPhone, but on the iPad the application was only being drawn on a small portion of the screen - just like what happened on the iPhone when I tried using the ShowAll policy.

  • Adding files and folders to a Root Folder (inode/directory)

    - by xBaldwin
    Ok so I'm fairly new to Ubuntu and wasn't even the one who put it one this computer(my friend did while I was storing it at his house because I was in the middle of transitioning between houses), but It's on here so I need to learn what I can so I can use it more effectively. My question at the moment is "Would it be safe to add files/folders to a folder (inode/directory) that requires Root access?" I continue to be informed by the system that the directory I am using is running low on space which I found odd seeing how I should have a lot more room on this computer. That's when I started looking at the directories and found that there are two with a bunch of un-used space on them. One says it has 46.9 GB of free space and the other has 24.9 GB of free space. Seems like a complete waste to not use that space and yet they both say they require Root access to add to them. I know that Root folders and files are normally all system folders and files. I also know that changing or deleting them can mess up the computer which right now I cant afford to do. I just don't know if it would mess anything up to add something to those folders. Thank you in advance to anyone who takes the time to reply and try to teach me about how all that works. I really do appreciate it and will do the same if by some crazy (completely unlikely) reason I have an answer to your question. :-)`

  • emacs keybindings

    - by Max
    I read a lot about vim and emacs and how they make you much more productive, but I didn't know which one to pick. Finally when I decided to teach myself common lisp, the decision was straight forward: everybody says that there's no better editor for common lisp, than emacs + slime. So I started with emacs tutorial and immediately I ran into something that seems very unproductive to me. I'm talking about key bindings for cursor keys: forward/backward: Ctrl+f, Ctrl+b up/down: Ctrl+p, Ctrl+n I find these bindings very strange. I assume that fingers should be on their home rows (am I wrong here?), so to move cursor forward or backward I should use my left index finger and for up and down right pinky and right index fingers. When working with any of Windows IDEs and text editors to navigate text I usually place my right hand in a position so that my thumb is on the right ctrl and my index, ring and middle fingers are on the cursor keys. From this position it is very easy and comfortable to move cursor: I can do one-character moves with my 3 right fingers, or I can press ctrl with my right thumb and do word-moves instead. Also I can press shift with my left pinky and do single-character or word selections. Also it is a very comfortable position to reach PgUp, PgDn, Home, End, Delete and Backspace keys with my right hand. So I have even more navigation and selection possibilities. I understand that the decision not to use cursor keys is to allow one to use emacs to connect to remote terminal sessions, where these keys are not supported, but I still find the choice of cursor keys very unfortunate. Why not to use j, k, i, l instead? This way I could use my right hand without much finger stretching. So how is emacs more productive? What am I doing wrong?

  • Touchpad not working on HP

    - by Grayson
    Everything worked fine in Ubuntu 10.04, flawless in fact, I admired the way the Operating System had handled such a unique touchpad so well. I have an HP Pavilion dv6. The touchpad and left, middle, and right click buttons are all on the trackpad, and it the bottom end depresses to click accordingly for each kind of click. In 10.04, everything worked fine, upon upgrading to Ubuntu 10.10 things became... odd. The scroll on the side would work, as would the left click. The right click wouldn't work however, but if you would lightly tap the exact right corner of the touchpad, the right click menu would come up, though it was inconsistent and difficult to make it do so. I have applied a fix I found on the older Ubuntu Forums for a similar issue, and it restored the normal left and right click, but it isn't as fluid, and there isn't the vertical scroll feature, which I do rather like to have... I would just like things to be as it was, if this is possible, please, please tell me how to do so. Thank you.

  • Maker Faire Report - Teaching Kids Java SE Embedded for Internet of Things (IoT)

    - by hinkmond
    I had a great time at this year's Maker Faire 2014 in San Mateo, Calif. where Jake Kuramoto and the AppsLab crew including Noel Portugal, Anthony Lai, Raymond, and Tony set up a super demo at the DiY table. It was a simple way to learn how Java SE Embedded technology could be used to code the Internet of Things (IoT) devices on the table. The best part of our set-up was seeing the kids sit down and do some coding without all the complexity of a Computer Science course. It was very encouraging to see how interested the kids were when walking them through the programming steps, then seeing their eyes light up when telling them, "You just coded a Java enabled Internet of Things device!" as the Raspberry Pi-connected devices turned on or started to move from their Java Embedded program. See: The AppsLab at Maker Faire It will be interesting to see how this next generation of kids grow up with all these Internet of Things devices around them and watch how they will program them. Hopefully, they will be using Java SE Embedded technology to do so. From the looks of it at this year's Maker Faire, we might have a bunch of motivated young Java SE Embedded coders coming up the ranks soon. Well, they have to get through middle school first, but they're on their way! Hinkmond

  • Memory allocation strategy for the vertex buffers (DirectX 10/11)

    - by Alex
    I have the following question. I write CAD system. So I have a 3D scene and there are many different objects (walls, doors, windows and so on). User can add or delete some objects. The question is: how can I organise the keeping of vertices for all my objects. I can create vertex buffer for every object. But I think drawing/switching from one buffer to another would have performance penalty. Another way - I can create several big buffers for every object type. But I don't understand how to update such buffers. It is too big to update whole buffer (for example buffer for all walls). What I need to do if I want to delete the object from the middle of the buffer? Actually I have the similar question: http://stackoverflow.com/questions/5515700/how-to-properly-update-vertex-buffers-in-directx-10 Most examples I've found work with very static models. Therefore, they tend to create a single vertex buffer with their list of points, and then are just manipulated by matrix transformations. I, on the other hand, will be updating the scene very often.

  • Why are "Inverted Colors" considered an accessibility feature? [migrated]

    - by RLH
    Why is it that in Apple software (OS X and iOS,) the "Inverted Colors" display feature is considered an accessibility option? I understand that some users are color-blind. This would justify the Black & White, or grey-scale modes. What I don't understand is how or why does inverting the display color help someone with any specific, visual impairment or dysfunction. As a programmer that wants to understand the need so that I can develop better, accessible software, what purpose does this feature serve to the end user who has some form of visual impairment? NOTE: I felt that this was a hard question to categorize on StackExchange. I settled here on Programmers because I assume that questions of accessibility are important to all developers and this question sits somewhere in the middle between topics that StackOverflow and SuperUser may cover. Also, this question isn't specific to Apple software. I've just noticed that this feature has been available on Macs for a very long time, it's a feature on iOS, and it's always associated with the Accessibility settings. If I can garner some information regarding the needs of some users, I think that I can develop better, accessible software.

  • Tech Article: Tired of Null Pointer Exceptions? Use Java SE 8's Optional!

    - by Tori Wieldt
    A wise man once said you are not a real Java programmer until you've dealt with a null pointer exception. The null reference is the source of many problems because it is often used to denote the absence of a value. Java SE 8 introduces a new class called java.util.Optional that can alleviate some of these problems. In the tech article "Tired of Null Pointer Exceptions? Use Java SE 8's Optional!" Java expert Raoul-Gabriel Urma shows you how to make your code more readable and protect it against null pointer exceptions. Urma explains "The purpose of Optional is not to replace every single null reference in your codebase but rather to help design better APIs in which—just by reading the signature of a method—users can tell whether to expect an optional value. In addition, Optional forces you to actively unwrap an Optional to deal with the absence of a value; as a result, you protect your code against unintended null pointer exceptions." Learn how to go from writing painful nested null checks to writing declarative code that is composable, readable, and better protected from null pointer exceptions.

  • Any empirical evidence on the efficacy of CMMI?

    - by mehaase
    I am wondering if there are any studies that examine the efficacy of software projects in CMMI-oriented organizations. For example, are CMMI organizations more likely to finish projects on time and/or on budget than non-CMMI organizations? Edit for clarification: CMMI stands for "Capability Maturity Model Integration". It's developed by the Software Engineering Institute at Carnegie-Mellon University (SEI-CMU). It's not a certification, but there are various companies that will "appraise" your organization to various levels of CMMI, such as level 2 and level 3. (I believe CMMI level 1 is an animalistic, Hobbesian free-for-all that nobody aspires to. In other words, everybody is at least CMMI level 1, even if you've never heard of CMMI before.) I'm definitely not an expert, but I believe that an organization can be appraised for CMMI levels within different scopes of work: i.e. service delivery, software development, foobaring, etc. My question is focused on the software development appraisal: is an organization that has been appraised to CMMI Level X for software projects more likely to finish a software project on time and on budget than another organization that has not been appraised to CMMI Level X? However, in the absence of hard data about software-oriented CMMI, I'd be interested in the effect that CMMI appraisals have on other activities as well. I originally asked the question because I've seen various studies conducted on software (e.g. the essays in The Mythical Man Month refer to numerous empirical studies, as does McConnell's Code Complete), so I know that there are organizations performing empirical studies of software development.

  • How does the new google maps make buildings and cityscapes 3D?

    - by Aerovistae
    Anyone who's seen the new Google maps has no doubt taken note of the incredible amount of three-dimensional detail in select American cities such as Boston, New York, Chicago, and San Francisco. They've even modeled the trees, bridges and some of the boats in the harbor! Minor architectural details are present. It's crazy. Looking at it up close, I've found there's a rectangular area around each of those cities, and anything within them is 3Dified, but it cuts off hard and fast at the edge, even if it's in the middle of a building. The edge of the rectangle is where the 3D stops. This leads me to think it's being done algorithmically (which would make sense, given the scale of the project, how many trees and buildings and details there are), and yet I can't imagine how that's possible. How could an algorithm model all these things without extensive data on their shapes and contours? How could it model the individual wires of a bridge, or the statues in a park? It must be done by hand, and yet how could it be for so much detail! Does anyone have any insight on this?

  • Is my client correct that I cannot take a vacation as a subcontractor? [closed]

    - by Rae Ann
    I have 2 clients who I do ongoing work for as a subcontractor. Both are sporadic and part-time. Company A sent me to a 3 day certification course out of state. The following week I was scheduled for a 3 day vacation. I warned company B three weeks prior to these events. During my training that Company A was paying for, Company B asked me to leave the training to workon something for them that needed immediate attention. I declined. However I made arrangements to work on it in the evening and in the early mornings after they threatened to take the work and all subsequent work for this client to someone else. I lost all networking and fun from that trip... The following week I was in Florida and was again asked to do more work on the project after the feedback from the client. The integrated product personnel would not cooperate/return any of our calls so I did the best I could. I turned in the work, explained the issue and then was gone for 3 hours. When I returned, all my access to the project had been revoked and after a week of my calls and emails I found out they replaced me. I sent an invoice 3 weeks ago and they tell me they owe me nothing because I did not do the whole project and they cannot bill the client for what I did, because they are billing for the second contractor who started over. I was told that they realize I was on vacation but as a subcontractor I lose the ability to just disappear. I was gone 3 hours! Is this normal, correct, legal?? Not only did they ruin my class and my vacation, but now they expect me to not demand payment? They ended our relationship and I was in the middle of another project of theirs too. They told me to immediately cease all work for them. How do I get paid for the work I have yet to invoice this month?

  • My first blog post…

    - by steveh99999
    I’ve been meaning to start a blog for a while now, (OK, for several years…..) - finally now, here it begins First post, something really simple but, a wise-man once told me about the best way to improve SQL server performance. Store Less Data. That's it.. that's all there is to it... Over the years, I've seen the following :- -  a 200Gb database which held 3 days data. Once business requirements changed, we were able to hold only 1 days data in this database. -  a table developed by DBAs to hold application table cardinality information - that information was collected at 2 hour intervals every day for 7 years ! After 7 years the DBA space-info table had become the largest table in the database - 60 million rows !  It was a simple change to remove alot of the historical intra-day data and change the schedule to run only once per evening. Suddenly that table held 6 million rows instead of 60 million.... - lots of backup and restore history held in msdb. See this post by Brent Ozar for more details on this issue. Imagine how much faster the backups, DBCC Checks and reindexes ran when the above 3 changes were implemented ?   How often do you review your big databases \ tables to see if you’re actually holding only data that is really required by the business ?

  • 3 column layout with css display table, with first row having multiple rows?

    - by Damainman
    I am working on a new website which: Has 3 columns - Each Column being a cell First column has 3 rows (Logo, Nav, icons) - Has a Div with display: table which wraps arround 3 divs with display:table-row. Other two columns only have 1 row. With the middle column being the content area. However since this is my first time using display:table, I am running into some things that aren't so clear to me. I was trying to avoid floating divs. If I need multiple rows with one cell in each row per column, do I embed each cell in a row or just create each row and not declare cells. I understand that browsers automatically create the missing elements but I want to make sure I do this properly to avoid any side effects that might occur due to the browser automatically creating the missing elements. Edit: I think my brain is just over worked, I guess I can accomplish this by just using 3 divs in the first column instead of using a nested table div with the rows. This just popped into my head.
