  • Building a database class in PHP

    - by Sprottenwels
    I wonder if I should write a database class for my application, and if so, how to accomplish it? Over there on SO, a guy mentioned it should be written as an abstract class. However, I can't understand why this would be a benefit. Do I understand correctly, that if I would write an abstract class, every other class that methods will need a database connection, could simply extend this abstract class and have it's own database object? If so, how is this different from a "normal" class where I could instantiate an database object? Another method would be to completely forget about my own class and to instantiate a mysqli object on demand. What do you recommend?

  • I can't get ubunutu installation to start

    - by tyler
    AZUS Sabertooth Motherboard, Intel I5 2500 CPU, Windows 7 installed I'm trying to install linux. I first attempted to install pin guy. I burned the ISO; booted from it; got the initial menu; attempting either run the live version from DVD, or install to system; the process stops at a blank screen with the blinking cursor in left corner. So I downloaded Ubuntu and got the same results. Then tried wubi, and ended up in the same position; blinking cursor in left corner.

  • What are the cons of using DrawableGameComponent for every instance of a game object?

    - by Kensai
    I've read in many places that DrawableGameComponents should be saved for things like "levels" or some kind of managers instead of using them, for example, for characters or tiles (Like this guy says here). But I don't understand why this is so. I read this post and it made a lot of sense to me, but these are the minority. I usually wouldn't pay too much attention to things like these, but in this case I would like to know why the apparent majority believes this is not the way to go. Maybe I'm missing something.

  • Simple Scripting for your Exalogic Storage

    - by Trond Strømme
    As part of my job in Oracle ACS (Advanced Customer Services) I'm handling lots of different systems and customers. Among the recent systems I worked with have been Oracle's Exalogic engineered systems. One of the things I'd never had much exposure to as a system developer/architect/middleware guy/Java dude has been storage; outside of consuming it for my photography needs.. Well, I'm always ready for a new challenge... I'd downloaded the 7000 series storage simulator when it was released in the good old Sun days, found it fun and instructive to play around with, but as I never touched storage in any way (besides consuming it..) I forgot about it. A couple of years ago when I started working with Exalogic engineered systems it again came into light as an invaluable learning and testing tool for the embedded storage in an Exalogic;  Oracle's Sun ZFS Storage 7320 Appliance.  aaaanyway... I've been "booted" into a part-time role as the interim storage/system admin/middleware/Java guy for a client and found I needed to create the occasional report or summary or whatever.. of what's using the storage in the 7320 (as default configured for an Exalogic, 40T of disk in a mirrored configuration, yielding 18T of actual space.) Reading the nice documentation and some articles on the Oracle Technology Network I saw great possibilities with the embedded ECMAScript3/JavaScript engine in the 7000 series.  In my personal opinion anyone who's dealing with Exalogic administration, or exposed to any of the 7000 series of storage appliances and servers that Oracle offers should have a VirtualBox instance of it kicking around. For development and testing it's a fantastic tool. (It can save you from explaining (most) of the embarrassing FAILS you can do if you test something in a production system to your management...) So download, and install.  A small sidestep, if after firing up the 7000 series simulator in VirtualBox you've forgotten what it's IP address is, the following will sort you out if you log in directly via the running VirtualBox VM. So in my case I can ssh to 192.168.56.101 or point a browser to https://192.168.56.101:215 to log into the storage appliance. One simple way of executing a script on the 7320 is to ssh to the device and redirecting a file with the script in it to ssh. ssh [email protected] < myscript.js One question I got from my client and the people who will take over the systems was: "how can we see the quotas and allocations for all projects/shares in one easy go so we don't have to go navigating around in the BUI for all the hundreds of shares the 7320 is hosting just to check if anything is running dry?" Easy! JavaScript time, VirtualBox and emacs! //NOTE! this script is available 'as is' It has ben run on a couple of 7320's, (running 2010.08.17.3.0,1-1.25 & // 2011.04.24.1.0,1-1.8) a 7420 and the VB image, but I personally //offer no guarantee whatsoever that it won't make your server topple, catch fire or in any way go pear shaped.. //run at your own risk or learn from my code and or mistakes.. script run('cd /'); run('shares'); //get all projects: proj = list(); function spaceToGig(bytes){ return bytes/1073741824; //convert bytes to GB } function fullInPercent(quota, space_data){ tmp = (space_data/quota)*100; return tmp; } //print header, slightly good looking printf(" %s/%-15s %8s(GB) %7s(GB) %5s(GB) %7s(GB) %3s\n","Project", "Share","Quota","Ref", "Snap", "Total","%full"); printf("-------------------------------------------------------------------------------\n") //for each project, get all shares. check for quota and calculate percentage and human readable figures.. for (i=0;i<proj.length;i++){ run('select ' + proj[i]); //get all shares for a project var pshares = list(); //for each share get quota properties for (j=0;j<pshares.length;j++){ run('select ' + pshares[j]); quota = get('quota'); //properties associated with a share or inherited from a project spaceData = get('space_data'); spaceSnap = get('space_snapshots'); spaceTotal = get('space_total'); if(quota>0){ //has quota printf(" %s/%-15s \t%4.2fGB\t%.2fGB\t%.2fGB\t%.2fGB\t%5.2f%%\n",proj[i], pshares[j],spaceToGig(quota),spaceToGig(spaceData),spaceToGig(spaceSnap),spaceToGig(spaceTotal),fullInPercent(quota,spaceTotal)); }else{ //no quota printf(" %s/%-15s \t%8s\t%.2fGB\t%.2fGB\t%.2fGB\t%s\n",proj[i],pshares[j], "N/A", spaceToGig(spaceData),spaceToGig(spaceSnap),spaceToGig(spaceTotal),"N/A"); } run('cd ..'); } run('done'); } The resulting output should look something like this: Project/Share Quota(GB) Ref(GB) Snap(GB) Total(GB) %full ------------------------------------------------------------------------------- ACSExalogicSystem/domains N/A 0.04GB 0.00GB 0.04GB N/A ACSExalogicSystem/logs N/A 0.01GB 0.00GB 0.01GB N/A ACSExalogicSystem/nodemgrs N/A 0.00GB 0.00GB 0.00GB N/A ACSExalogicSystem/stores N/A 0.04GB 0.00GB 0.04GB N/A ***_dev/FMW_***_1 133GB 4.24GB 0.01GB 4.25GB 3.19% ***_dev/FMW_***_2 N/A 4.25GB 0.01GB 4.26GB N/A ***_dev/applications 10GB 0.00GB 0.00GB 0.00GB 0.00% ***_dev/domains 50GB 10.75GB 3.55GB 14.30GB 28.61% ***_dev/logs 20GB 0.32GB 0.01GB 0.33GB 1.66% ***_dev/softwaredepot 20GB 4.15GB 0.00GB 4.15GB 20.73% ***_dev/stores 20GB 0.01GB 0.00GB 0.01GB 0.05% ###_dev/FMW_###_1 400GB 17.63GB 0.12GB 17.75GB 4.44% ###_dev/applications N/A 0.00GB 0.00GB 0.00GB N/A ###_dev/domains 120GB 14.21GB 5.53GB 19.74GB 16.45% ###_dev/logs 15GB 0.00GB 0.00GB 0.00GB 0.00% ###_dev/softwaredepot 250GB 73.55GB 0.02GB 73.57GB 29.43% …snip My apologies if the output is a bit mis-aligned here and there, I only bothered making it look good, not perfect :/ I also removed some of the project names (*,#)

    On Monday, Tom LaRock ( b /@sqlrockstar) presented his #MemeMonday topic as What #SQLFamily Means To Me . The #sqlfamily hash tag is a relatively new one, but is amazingly appropriate. I've been working with relational databases for almost 20 years, and for most of that time I've been the lone DBA.

  • Small-Scale Physics Engine

    - by user1276078
    I'm entering Android game development, and I already have a computer version of a game I want to publish. The thing is, I want to make this as good as it can be. With that said, I need a physics engine, really to only do one thing. That one thing is to make a parabolic movement of my main character as he's jumping in the air. Currently, my computer version simply makes the guy move up at a 45 degree angle, and as soon as it hits the ceiling, down at a 45 degree angle. I need a physics engine/library that would accomplish that, it has to be in java since that's my best language, it has to be 2D, and it has to be able to work on Android. Which physics engine/library could accomplish all of that?

  • Some mail details about Orange Mauritius

    Being an internet service provider is not easy after all for a lot of companies. Luckily, there are quite some good international operators in this world. For example Orange Mauritius aka Mauritius Telecom aka Wanadoo(?) aka MyT here in Mauritius. The local circumstances give them a quasi-monopol position on fixed lines for telephony and therefore cable-based DSL internet connectivity. So far, not bad but as usual... the details. Just for the records, I am only using the services of Orange for mobile but friends and customers are bound, eh stuck, with other services of Orange Mauritius. And usually, being the IT guy, they get in touch with me to complain about problems or to ask questions on either their ADSL / MyT connection, mail services or whatever. Most of those issues are user-related and easily to solve by tweaking the configuration of their computer a little bit but sometimes it's getting weird. Using Orange ADSL... somewhere else Now, let's imagine we are an Orange ADSL customer for ages and we are using their mail services with our very own mail address like "[email protected]". We configured our mail client like Thunderbird, Outlook Express, Outlook or Windows Mail as publicly described, and we are able to receive and send emails like a champion. No problems at all, the world is green. Did I mention that we have a laptop? Ok, let's take our movable piece of information technology and visit a friend here on the island. Not surprising, he is also customer of Orange, so we can read and answer emails. But Orange is not the online internet service provider and one day, we happen to hang out with someone that uses Emtel via WiMAX or UMTS.. And the fun starts... We can still receive and read emails from our Orange mail account and the IT world is still bright but try to send mails to someone outside the domain "@intnet.mu" or "@orange.mu". Your mail client will deny sending mail with SMTP message 5.1.0 "blah not allowed". First guess, there is problem with the mail client, maybe magically the configuration changed over-night. But no it is still working at home... So, there is for sure a problem with the guy's internet connection. At least, it is his fault not to have Orange internet services, so it can not work properly... The Orange Mail FAQ After some more frustation we finally checkout the Orange Mail FAQ to see whether this (obviously?) common problem has been described already. Sorry, but those FAQ entries are even more confusing as it is not really clear how to handle this scenario. Best of all is that most of the entries are still refering to use servers of the domain "intnet.mu". I mean Orange will disable those systems in favour of the domain "orange.mu" in the near future and does not amend their FAQs. Come on, guys! Ok, settings for POP3 are there. Hm, what about the secure version POP3S? No signs at all... Even changing your mail client to use password encryption with STARTTLS is not allowed at all. Use "bow.intnet.mu" for incoming mail... Ahhh, pretty obvious host name. I mean, at least something like pop.intnet.mu or pop3.intnet.mu would have been more accurate. Funny of all, the hostname "pop.orange.mu" is accessible to receive your mail account. Alright, checking SMTP options for authentication or other like POP-before-SMTP or whatever well-known and established mechanism to send emails are described. I guess that spotting a whale or shark in Mauritian waters would be easier. Trial and error on SMTP settings reveal that neither STARTTLS or any other connection / password encryption is available. Using SSL/TLS on SMTP only reveals that there is no service answering your request. Calling customer service So, we have to bite into the bitter apple and get in touch with Orange customer service and complain/explain them our case and ask for advice. After some hiccups, we finally manage to get hold of someone competent in mail services and we receive the golden spoon of mail configuration made by Orange Mauritius: SMTP hostname: smtpauth.intnet.mu And the world of IT is surprisingly green again. Customer satisfaction? Dear Orange Mauritius, what's the problem with this information? Are you scared of mail spammer? Why isn't there any case in your FAQs? Ok, talking about your FAQs - simply said: they are badly outdated! Configure your mail client to use server name based in the domain intnet.mu but specify your account username with orange.mu as domain part. Although, that there are servers available on the domain orange.mu after all. So, why don't you provide current information like this: POP3 server name: pop.orange.muSMTP server name: smtp.orange.muSMTP authenticated: smtpauth.orange.mu It's not difficult, is it? In my humble opinion not really and you would provide clean, consistent and up-to-date information for your customers. This would produce less frustation and so less traffic on your customer service lines. Which after all, would improve the total user experience and satisfaction level on both sides. Without knowing these facts. Now, imagine you would take your laptop abroad and have to use other internet service providers to be able to be online... Calling your customer service would be unnecessary expensive!

  • Kansas City Developer's Conference

    - by Brian Schroer
    I just found about about / registered for Saturday’s Kansas City Developer’s Conference, and am going to make the drive over from the right side of the state (Hey, no offense, KC – I’m just looking at a map, and St. Louis is on the right side, Kansas City’s on the left). (I’m sure the event’s been mentioned on geekswithblogs several times, but I’m on a “staycation” this week, getting cabin fever, and noticed @leebrandt’s tweet today.) I’m looking forward to some of the presentations in the Agile and Patterns tracks. I’m going to have to get up pretty early Saturday morning to descend from St. Louis to Kansas City (Again, no offense – St. Louis is just at a higher elevation*, that’s all), so if you see a tired-looking guy wandering around wearing a St. Louis Day of .NET shirt, please be nice. I’m not sure how much longer registration will be open, but here’s the link: http://kcdc.eventbrite.com/ *Not true – St. Louis is closer to sea level than Kansas City, but I’ll start my drive from the top of the Arch, OK?

  • How to explain to a layperson the variance in programmer rates?

    - by Matt McCormick
    I recently talked to a guy that is looking for developers to build a product idea. He mentioned he has received interest from people but the rates have varied from $20-120/hr. This project he estimates should take 3-6 months and since he is non-technical, he is confused why there can be so much variance. I understand how I would choose someone but I am a developer and can gauge other people's work. How can I explain to him (in a non-biased way, if possible, as I will apply as well) about the variance in rates? Is there any good analogy that would help?

  • Working on someone else's code

    - by Xavi Valero
    I have hardly a year's experience in coding. After I started working, most of the time I would be working on someone else's code, either adding new features over the existing ones or modifying the existing features. The guy who has written the actual code doesn't work in my company any more. I am having a hard time understanding his code and doing my tasks. Whenever I tried modifying the code, I have in some way messed with the working features. What all should I keep in mind, while working over someone else's code?

  • Point domain to 3rd Party DNS

    - by PhilCK
    I have a few of domain names and a rather simple website (small company type thing). We are in the process of having a web designer create a new website for us, but I don't want to give access to the control panel for the domain names (and have no way to limit it, it seems), while at the same time I don't want to be the go between guy for it the settings. Is there a way or a service for me to point the domain's at a 3rd party DNS system, that I can then give access for the web designer, without worry that he can find my personal info or try and transfer my domain out. Thanks.

  • Why C++ is an abomination [closed]

    - by Chander Shivdasani
    Possible Duplicate: Why do so many people dislike C++? I was reading the blog by Peter Seibel (Author of Coders at Work) where brilliant programmers like Ken Thompson, Joshua Bloch and Guy Steele have despised c++ to no end. What is it in C++ that people hate so much? And despite so much hate towards it, companies like Google are still using it, and some of the programmers who snubbed C++ have worked or are already working at Google. So, what is it in the language that despite so much hate from top programmers, it's still used at most of the places? I haven't really used C++ beyond academic projects, so i don't know much about the disadvantages of the language. What do programmers here think about it? --Chander

  • On technical talent

    - by Rob Farley
    In honour of the regular T-SQL Tuesday blogging, the UnSQL theme started, looking at topics that were not directly SQL related, but nevertheless quite interesting. This is the brainchild of Jen McCown, who posted the second of these recently. I’m actually a bit late in responding, as I haven’t got it in my head to look for these posts yet. Still, Jen says I can still contribute now, hence this post. The theme this time is on Tech Giants. I could list people all day for those I admire in the SQL Server space, and go on even longer if I branch out to other areas. But I actually want to highlight four guys that I admire so much for their skills, integrity and general awesomeness that I hired them. Yes – the guys that work for me at LobsterPot Solutions, being Ben McNamara, David Gardiner, Roger Noble and Ashley Sewell. I admire them all, and they present the company with a platform on which to grow.

  • UML Class diagrams with Java packages?

    - by loosebruce
    I am trying to model in UML 2.0 a Java servlet application that has three classes Servlet class; essentially a main class that acts as the controller DatabaseLogic; contains methods for database operations XMLBuilder; builds an XML from a query result string The classes use a variety of packages from the Java library. I am unsure how to model this in UML Do I have to create a package and show which libraries are used for each individual class or can I just have one large package in the diagram with all the libraries showing which classes have dependencies on which. As per this diagram This is my first time working with java properly (im a C++ guy) Apart from being a bit messy , is this a correct UML representation of the system I described? Does a Package in UML mean the same as a Package in Java?

  • Do I create new site or add to existing site?

    - by nitbuntu
    Hi, Suppose, as an example, I have a website with the address, www.cool-gifts.com and I'm getting regular sales and its a worthwhile site, but no great fireworks. After research I find that there is a great market for '2nd hand stuff' and I'd like to serve that market. Would it be best to add '2nd hand stuff' as an additional category of gifts in my existing site....or, since the 2nd hand stuff is a market in itself, would I be better off investing time and energy bringing up a whole new site (www.used-stuff.com)? If I had employees and financial resources, it probably would be a no-brainer...start a new site. But, what if you are a small guy, with limited resources? So...new site....or add to existing site?

  • Customising Google Maps breaks highway label blocks

    - by user2248809
    I'm trying to customise a Google map to use shades of a particular colour. It's working nicely except the blocks that contain major road names / numbers is illegible. I've figured out how to target styles to those elements, but setting the 'color' value sets both text and background to that colour. And no adjusting of saturation, gamma, lightness etc seems to make the text legible. function initialize() { var latlng = new google.maps.LatLng(50.766472,0.284732); var styles = [ { stylers: [ { "gamma": 0.75 }, { "hue": "#607C75" }, { "saturation": -75 }, { "lightness": 0 } ] },{ featureType: "water", stylers: [ {color: "#607C75"} ] } ]; var myOptions = { zoom: 15, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, }; var marker = new google.maps.Marker({ position: latlng, title:"Living, dining, bedrooms by David Salmon" }); var map = new google.maps.Map(document.getElementById("map"), myOptions); map.setOptions({styles: styles}); marker.setMap(map); }

  • Chicago Architects Group &ndash; Document Generation Architectures

    - by Tim Murphy
    Thank you to everyone who came out to the Chicago Architects Group presentation last night.  It seemed like the weather has a way of keeping a large portion of the people who registered from making the meeting.  There was some lively networking going on before and after the meeting.  I enjoyed the questions that people had during the presentation.  It helped to bring out some of the challenges with dealing with the OOXML and ODF standards from an architecture perspective. I have posted the Slides and Code.  Feel free to contact me with any questions. For those of you who missed the presentation I will be giving a similar one at the Lake County .NET Users Group on June 24th. The next CAG presentation will be July 20th.  The presentation will be Architecting A BI Installation by David Leininger.  Look for the registration to open in the next day or so. del.icio.us Tags: Chicago architects Group,OOXML,ODF,BI,LCNUG,slides,code

  • Tiled/TMX C++ Library/Parser

    - by Ben
    Where can I find an easy to use and up to date C++ parser/library for the .tmx map format (used by the Tiled Map Editor) ? EDIT: David's comment, 'Unless you want to build your game around the format of the parser..', got me thinking... So I have downloaded pugixml, which is an easy to use xml-parser with very straightforward documentation. Together with the spec for the TMX Map Format, I think I'll give it a try myself. I'll probably compare with Cocos2d-x's CCTMXTiledMap at some point.

  • How do you answer "Rate yourself" questions?

    - by Vinoth Kumar
    Hi , I have been frequently asked questions like "Rate yourself in java" It goes like interviewer : Rate yourself in java on the scale of 10 me: 9 interviewer : Rate yourself in J2EE me : 8 .... But really I just come up with arbitrary numbers. Sure I know Java well , but what does it mean to say "9 out of 10" . I think it is a very subjective question, that does not make sense overall. The problem is ,if I say 9 , If I am not able to answer any question , the interviewer might think , "this guy just said 9" . On the other hand If I said 6 , there is a good chance the interviewer might think "He rates himself this low...not good" How do you respond to such questions ?
