  • Une variante de Kinect adaptée aux ordinateurs sortira en 2011, Asus remplacera Microsoft dans ce projet

    Une variante de Kinect adaptée aux ordinateurs sortira en 2011, Asus remplacera Microsoft dans ce projet PrimeSense. Ce nom ne vous dit rien ? Il s'agit de l'entreprise israélienne qui a vendu les technologies clés du Kinect à Microsoft. Cette dernière travaille actuellement au développement d'un appareil similaire pour les PC... mais sans Microsoft ! A la place, la compagnie a décidé de s'associer avec le fabriquant Asus, pour offrir dans les mois à venir une interface de contrôle gestuel pour les ordinateurs (qui fonctionnera d'ailleurs avec toutes les machines, et pas seulement celles d'Asus). Le produit répondra au nom de Wavi Xtion et ne sera pas axé vers les jeux, mais plutôt vers la navigation (...

  • "En 2020, 80% des applications tourneront dans le cloud", déclare Microsoft, en expliquant que les DSI devront s'adapter à ces changements

    "En 2020, 80% des applications tourneront dans le cloud", déclare Microsoft, tout en expliquant que les DSI devront s'adapter à ces changements Au premier jour des TechDays 2011, nous avons pu rencontrer Jérôme Trédan, Directeur produits serveurs et infrastructure de cloud computing chez Microsoft France. Sa mission : encadrer une équipe de chefs de produits sur toute les lignes de produits serveurs, dans 3 grands domaines : les infrastructures (Windows Server, System Center et toute l'offre de sécurité de la gamme Forefront) ; l'axe des plateformes applicatives de Microsoft (SQL Server, Biztalk, .Net) ; et la partie infrastructures cloud computing (qui se développe très rapidement avec Windows et SQL Azure).

  • List all documents (webparts) and sites using a certain solution in sharepoint 2007

    - by tnolan
    I would like to uninstall a Sharepoint application template (GroupBoard Workspace to be exact) but I want to make sure nothing currently relies on it. I don't see any functions within stsadm that will tell me this information and I have even tried SPM which would work, but with such a huge site it's tedious to go through every single web and page to see which features are in use. Is there a way (probably with SQL using the id from stsadm -o enumsolutions) to list everything that relies on a template within a given solution, including webparts on custom pages? If this is not possible, what is the best way to check dependencies prior to uninstalling a solution (especially since GBW is not the only one on my axe list.) Note: I know that stsadm -o deletesolution will stop me from removing something that is in use, but I want to see all of the things that are using a given solution.

  • Any language where every class instance is a class too?

    - by Dokkat
    Taking inspiration from Javascript prototypes, I had the idea of a language where every instance can be used as a class. Before I potentially reinvent the wheel, I would like to ask if there is a language already using this concept: //To declare a Class, extend the base class (in this case, Type) Type(Weapon,{price:0}); //Same syntax to inherit; simply extend the parent: Weapon(Sword,{price:3}); Weapon(Axe,{price:4}); Sword(Katana,{price:7}); Sword(Dagger,{price:3}); //And the same to create an instance: Katana(myKatana,{nickname:"Leon"}); myKatana.price; // 7 myKatana.nickname; // Leon // An operator to return children of a class; Sword_; // [Katana, Dagger] // An operator to return array of descendants; Sword__; // [Katana, Dagger, myKatana] // An operator to return array of parents; Sword^; // Weapon // Arrays can be used as elements Sword__.price += 1; //increases price of Sword's descendants by 1 mySword.price; //8 // And to access specific element (using its name instead of index) var name = "mySword" Katana_[name]; // [mySword] Katana_[name].nickname; // Leon Has this kind of approach been already studied/implemented?

  • More Changes...

    - by MOSSLover
    Stuff has changed drastically for me in the past two to three years.  I moved over 1000 miles from Saint Louis.  I go outside and I get up in front of crowds with less issues.  Now I'm changing jobs again.  I'm not really sure what to say here.  I was obviously unhappy and I needed to do something different.  So quit two days ago and I guess it worked out that I end with B&R this Friday, then head to TEC and SPS Huntsville and a week from this Monday I start my new job at Gig Werks.  I'm not sure what to expect or where I'm heading, but I think it's a step in the right direction.  I won't really know what kind of impact this will have on my life for at least another 6 months to a year. For some reason I can't sleep tonight and I think it's really a reflection of my last day.  Tomorrow is an ending and a beginning at the same time.  So it's both kind of sad and exciting.  I don't know why I'm really excited to go to Disney Land for the second time ever in my life time.  I get to ride the Teacups.  For the longest time when I was a kid I wanted to go to Disney Land.  I wanted to ride the teacups.  In 2007, at the age of 25, I rode the teacups for my first ever visit to LA.  That was the start of finally syncing up with my childhood goals.  I wanted to live near a major city.  I wanted to visit all the major cities in the world.  I wanted to see everything and meet everyone.  This job change will probably turn into something great I just don't know it yet.  I'm walking again outside my comfort zone and stepping into uncharted territory.  In 2-3 years I'll probably write another blog post how this week lead to something great.  It just stinks when you have to leave behind something you know and love.  I will miss all my current colleagues, but I'm sure I'll gain some new ones and keep in touch with the old.  To 2010 being a great year for change and hopefully by the end of the year I can say I went to Europe.  To reaching my goals and my dreams.  Don't let anyone stop you from getting what you want in life (unless you are axe murderer please don't kill anyone that's just wrong).  Have a good weekend everyone!

  • Attaching new animations onto skeleton via props, a good idea?

    - by Cardin
    I'm thinking of coding a game with an idea of mine. I've coded 2D games before, but I'm new to 3D programming, so I'd like to ask if this idea of mine is feasible or out of my depth. I'm making a game where there are many different characters for the player to choose from (JRPG style). So to save time, I have an idea of creating many different varied characters using a completely naked body mesh and animation skeleton, standardised across all characters. For example, by placing different hair, boots, armor props on the character mesh, new characters can be formed. Kinda like playing dress-up with a barbie doll. I'm thinking this can be done by having a bone on the prop that I can programmically attach to the main mesh. Also, I plan to have some props add new animations to the base skeleton, so equipping some particular props would give it new attack, damage, idle animations. This is because I can't expect the character to have the same swinging animation if he had a big sword or an axe. I think this might be possible if the prop has its own instance of the animation skeleton with just only the new animations, and parenting the base body mesh to this new skeleton. So all the base body mesh has are just the basic animations, other animations come from the props. My concerns are, 1) the props might not attach to the mesh properly and jitter a lot, 2) since prop and body are animated differently, the props and base mesh will cause visual artefacts, like the naked thighs showing through the pants when the character walks, 3) a custom pipeline have to be developed to export skeletons without mesh, and also to attach the base body mesh to a new skeleton during runtime in the game. So my question: are these features considered 'easy' to code? Or am I trying to do something few have ever succeeded with on their own? It feels like all these can be done given enough time and I know I definitely have to do a bit of bone matrix calculations, but I really don't want to drag out the development timeline unnecessarily from coding mathematically intense things or analyzing how to parse 3D export formats. I'm currently only at the Game Design stage, so if these features aren't a good idea, I can simply change the design of the game. (Unrelated to question) I could always, as last resort, have the characters have predetermined outfit and weapon selections so as to animate everything manually.

  • Am I getting the right memory for my motherboard?

    - by Daniel Carvalho
    Hi technophiles; I have a Gigabyte GA-EP45-DS motherboard. Also, the memory that came with my computer was two Transcend aXe RAM 1066MHZ 1GB modules. The thing is, I noticed that my motherboard has "DDR2 1200" written on it. This concerns me, have I bought slower memory than my computer is supposed to have ideally? Now, I'm not super concerned at a granular level about the best optimal RAM with the best CAS latency etc... but I do hope at least that I've got the right speed. Now, as far as I know, there is no such thing as ram at 1200MHZ? Am I right? You see, because I'm thinking of getting more RAM now, before I can't find the same type or speed any-more and just want to make sure it's the right thing. Furthermore, if the memory is slower than what I should be getting for my motherboard, what RAM should I be getting, and will that new RAM play nice with my old RAM? If I get new RAM at a different speed, would it be better / more beneficial performance-wise to omit the old RAM because of how the whole DUAL channel RAM thing works? I'm not too clued up on this area. Thanks chiefs.

  • Select list auto update on any kind of change?

    - by Tom Irons
    I have a jQuery that when you click on a select option it will show the next one, but you have to click, you cant just use the down arrow or "tab" to the next option. I am wondering what options do I have to make this work? Here is my jQuery: function typefunction() { var itemTypes = jQuery('#type'); var select = this.value; itemTypes.change(function () { if ($(this).val() == '1-Hand') { $('.1-Hand').show(); $('.2-Hand').hide(); $('.off').hide(); $('.Armor').hide(); } else $('.1-Hand').hide(); if ($(this).val() == '2-Hand') { $('.2-Hand').show(); $('.1-Hand').hide(); $('.off').hide(); $('.Armor').hide(); } else $('.2-Hand').hide(); if ($(this).val() == 'Armor') { $('.Armor').show(); $('.2-Hand').hide(); $('.off').hide(); $('.1-Hand').hide(); } else $('.Armor').hide(); if ($(this).val() == 'Off-Hand') { $('.Off').show(); $('.2-Hand').hide(); $('.1-Hand').hide(); $('.Armor').hide(); } else $('.Off').hide(); if ($(this).val() == '1-Hand') { $('.one-hand-dps').show(); $('.item-armor').hide(); $('.two-hand-dps').hide(); } else $('.one-hand-dps').hide(); if ($(this).val() == '2-Hand') { $('.two-hand-dps').show(); $('.one-hand-dps').hide(); $('.item-armor').hide(); } else $('.two-hand-dps').hide(); if ($(this).val() == 'Armor') { $('.item-armor').show(); $('.one-hand-dps').hide(); $('.two-hand-dps').hide(); } else $('.item-armor').hide(); }); } And the HTML: <div class="input-group item"> <span class="input-group-addon">Type</span> <select id="type" name="type" class="form-control" onclick="typefunction(); itemstats(); Armor(); OffHand(); TwoHand();"> <option value="Any Type">Any Type</option> <option value="1-Hand">1-Hand</option> <option value="2-Hand">2-Hand</option> <option value="Armor">Armor</option> <option value="Off-Hand">Off-Hand</option> </select> </div> <div class="input-group item"> <span class="1-Hand input-group-addon" style="display: none;">Sub-Type</span> <select class="1-Hand form-control" name="sub[1]" style="display: none;"> <option value="All 1-Hand Item Types">All 1-Hand Item Types</option> <option>Axe</option> <option>Ceremonial Knife</option> <option>Hand Crossbow</option> <option>Dagger</option> <option>Fist Weapon</option> <option>Mace</option> <option>Mighty Weapon</option> <option>Spear</option> <option>Sword</option> <option>Wand</option> </select> </div> <div class="input-group"> <span class="2-Hand input-group-addon" style="display: none; ">Sub-Type</span> <select class="2-Hand form-control" name="sub[2]" style="display: none;"> <option>All 2-Hand Item Types</option> <option>Two-Handed Axe</option> <option>Bow</option> <option>Diabo</option> <option>Crossbow</option> <option>Two-Handed Mace</option> <option>Two-Handed Mighty Weapon</option> <option>Polearm</option> <option>Staff</option> <option>Two-Handed Sword</option> </select> </div> <div class="input-group"> <span class="Armor input-group-addon" style="display: none;">Sub-Type</span> <select class="Armor form-control" name="sub[3]" style="display:none;"> <option>All Armor Item Types</option> <option>Amulet</option> <option>Belt</option> <option>Boots</option> <option>Bracers</option> <option>Chest Armor</option> <option>Cloak</option> <option>Gloves</option> <option>Helm</option> <option>Pants</option> <option>Mighty Belt</option> <option>Ring</option> <option>Shoulders</option> <option>Spirit Stone</option> <option>Voodoo Mask</option> <option>Wizard Hat</option> </select> </div> <div class="input-group"> <span class="Off input-group-addon" style="display: none;">Sub-Type</span> <select class="Off form-control" name="sub[4]" style="display:none;"> <option>All Off-Hand Item Types</option> <option>Mojo</option> <option>Source</option> <option>Quiver</option> <option>Shield</option> </select> </div>

  • Gamify your Web

    - by Isabel F. Peñuelas
    Yesterday Valencia welcomed the Gamification World Congress that I follow virtually through #GWC2012. BBVA, Iberia, Ligeresa, Axe, Wayra, ESADE, GlaxoSmithKline, Macmillan, Gamisfaction, Nomaders, Blaffin were among the companies presenting success stories on gaming. It has been proved that people remember things easily when an emotion is created. The marketing expectations around Gamification techniques have a lot to do with Neuromarketing theories. There are a lot of expectations on internal enterprise Gamification. In the public Web some sectors are taking the lead on following the trend. The Gartner Analyst Brian Burke opened another Gamification recent event in Madrid remembering that “Gamification is mostly about Engagement”, and this can be applied both to customers or employees. Gamification and Banking The experience of the Spanish Financial Group BBVA that just launched BBVA Game was also presented a week ago at the BBVA Innovation Centre during the event “Gamification & Banking: a fad or a serious business?” . One of the objectives of the BBVA Game was to double the name of registered users. “People like the efficiency of the online channel want to keep a one-to-one contact with the brand”-explained Bernardo Crespo. Another interested data coming out the BBVA presentation was that “only 20% of Spanish users –out of the total holders of Bank Accounts in the country- is familiar with the use of a Web Site to consult their bank accounts”, the project aims also to reverse this situation helping people to learn making a heavy use of the Video in the gaming context. In general Banking presenters seem to agree that Gamification techniques are helping to increase the time spent on the Web. Gamification and Health Using Gamification techniques for chronic illness rehabilitation was another topic of the World Congress. Here you can find some ideas and experiences What can games do for the health (In Spanish) I have personally started my own mental-health gaming project at http://www.lumosity.com/ Gamification in the Enterprise I really recommend Reading this excellent post of Ultan ÓBroin my Introduction to Gamification and Applications. Employee´s motivation and learning are experiencing a 360º turn and it looks than some of us will become soon the Dragon of the year instead of the Employee of the Year. Using Web 2.0 Tools for Gamification Projects  What type of tools do we need for a quick-win Gamification project? To certain extend Gamification can be considered an evolution of the participative Web. Badging, avatars, points and awards, leader boards, progress charts, virtual currencies, gifting and giving challenges and quests are common components and elements. The Web is offering new development frameworks to that purpose as this Avatar Framework from Paypal or Badgeville to include in web applications. Besides, tools to create communities around a game are required to comment, share and vote players as well as for an efficient multimedia management. Due to its entirely open architecture, its community features, and its multimedia and imaging solutions is were I see WebCenter as a tool helping brands to success.

  • What Color is your Jetpack ?

    - by JoshReuben
    I’m a programmer, Im approaching 40, and I’m fairly decent at my job – I’ll keep doing what I’m doing for as long as they let me!   So what are your career options if you know how to code? A Programmer could be ..   An Algorithm developer Pros Interesting High barriers of entry, potential for startup competitive factor Cons Do you have the skill, qualifications? What are working conditions n this mystery niche ? micro-focus An Academic Pros Low pressure Job security – or is this an illusion ? Cons Low Pay Need a PhD A Software Architect Pros: strategic, rather than tactical Setting technology platform and high level vision You say how it should work, others have to figure out why its not working the way its supposed to ! broad view – you are paid to learn (how do you con people into paying for you to learn ??) Cons: Glorified developer – more often than not! competitive – everyone wants to do it ! loose touch with underlying tech in tough times, first guy to get the axe ! A Software Engineer Pros: interesting, always more to learn fun I can do it Fallback Cons: Nothing new under the sun – been there, done that Dealing with poor requirements, deadlines, other peoples code, overtime C#, XAML, Web - Low barriers of entry –> à race to the bottom A Team leader Pros: Setting code standards and proposing technology choices Cons: Glorified developer – more often than not! Inspecting other peoples code and debugging the problems they cannot fix Dealing with mugbies and prima donas Responsible for QA of others A Project Manager Pros No need for debugging other peoples code Cons Low barrier of entry High pressure Responsible for QA of others Loosing touch with technology A lot of bullshit meetings Have to be an asshole A Product Manager Pros No need for debugging other peoples code Learning new skillset of sales and marketing Cons Travel (I'm a family man) May need to know the bs details of an uninteresting product things I want to work with: AI, algorithms, Numerical Computing, Mathematica, C++ AMP – unfortunately, the work here is few & far between. VS & TFS Extensibility, DSLs (Workflow , Lightswitch), Code Generation – one day, code will write code ! Unity3D, WebGL – fun, fun, fun ! Modern Web – Knockout, SignalR, MVC, Node.Js ??? (tentative – I'll wait until things stabilize as this area is undergoing a pre-Cambrian explosion) Things I don’t want to work with: (but will if I'm asked to !) C# – same old, same old – not learning anything new here Old code – blech ! Environment with code & fix mentality , ad hoc requirements, excessive overtime Pc support, System administration – even after 20 years, people still ask you to do this sometimes ! debugging – my skills are just not there yet Oracle Old tech: VB 6, XSLT, WinForms, Net 3.51 or less Old style Web dev Information Systems: ASP.NET webforms, Reporting services / crystal reports, SQL Server CRUD with manual data layer, XAML MVVM – variations of the same concept, ad nauseaum. Low barriers of entry –> race to the bottom.  Metro – an elegant API coupled to a horrendous UX – I'll wait for market penetration viability before investing further in this.   Conclusion So if you are in a slump, take heart: Programming is a great career choice compared to every other job !

  • DynamicResource and Dynamic Items in ContextMenu on XamDataGrid

    - by miguel
    I would like to dynamically create a set of context menu options based upon some properties. Currently, I am creating a context menu as a DynamicResource with the visibility of the menu options bound to the properties, however, it seems that the DynamicResource is created only once, at runtime. Is this true? What I would like to do is have the menu generated each time, which will take into account the property changes on the data object. Please see the following XAML snippet: <Border DockPanel.Dock="Right" Margin="4,4,4,4" BorderBrush="Gray" BorderThickness="1" CornerRadius="3" > <igDP:XamDataGrid Height="Auto" Width="Auto" Style="{DynamicResource DefaultInfragisticsGridStyle}" Name="axeDataGrid" ActiveRecord="{Binding Path=SelectedItem, Mode=TwoWay}" DataSource="{Binding Path=Axes}" ContextMenuOpening="ContextMenuOpeningHandler"> <igDP:XamDataGrid.Resources> <Style TargetType="{x:Type igDP:DataRecordPresenter}" BasedOn="{x:Static Themes:DataPresenterAero.DataRecordPresenter}"/> <ContextMenu x:Key="RecordContextMenu"> <ContextMenu.Resources> <BooleanToVisibilityConverter x:Key="booleanToVisibilityConverter"/> </ContextMenu.Resources> <MenuItem Header="Cancel Axe" Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.CancelAxe}" Visibility="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.IsCancelAxeAllowed, Converter={StaticResource booleanToVisibilityConverter}, Mode=OneWay}"/> <MenuItem Header="Create RFQ" Command="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.CreateRFQ}" Visibility="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}, Path=DataContext.IsCreateRfqAllowed, Converter={StaticResource booleanToVisibilityConverter}, Mode=OneWay}"/> </ContextMenu> <Style TargetType="{x:Type igDP:DataRecordCellArea}"> <Setter Property="ContextMenu" Value="{DynamicResource RecordContextMenu}" /> </Style>

  • How can I draw on JPanel using another quadrant for the coordinates?

    - by Sanoj
    I would like to draw some shapes on a JPanel by overriding paintComponent. I would like to be able to pan and zoom. Panning and zooming is easy to do with AffineTransform and the setTransform method on the Graphics2D object. After doing that I can easyli draw the shapes with g2.draw(myShape) The shapes are defined with the "world coordinates" so it works fine when panning and I have to translate them to the canvas/JPanel coordinates before drawing. Now I would like to change the quadrant of the coordinates. From the 4th quadrant that JPanel and computer often uses to the 1st quadrant that the users are most familiar with. The X is the same but the Y-axe should increase upwards instead of downwards. It is easy to redefine origo by new Point(origo.x, -origo.y); But How can I draw the shapes in this quadrant? I would like to keep the coordinates of the shapes (defined in the world coordinates) rather than have them in the canvas coordinates. So I need to transform them in some way, or transform the Graphics2D object, and I would like to do it efficiently. Can I do this with AffineTransform too?

  • Retrieve specific preceding sibling nodes attributes

    - by Matthieu BROUILLARD
    Is there an XPath way of recovering directly one specific attribute of preceding sibling nodes of an XML node using an XPath query? In the following example, I would like to retrieve the values of the alt attribute of each img nodes that precede the div element marked with the id=marker. <content> <img alt="1" src="file.gif" /> <img alt="2" src="file.gif" /> <img alt="3" src="file.gif" /> <img alt="4" src="file.gif" /> <div id='marker'></div> </content> For this example, I want to retrieve the values 1 2 3 4. I use the following XPath query //div[@id='marker']/preceding-sibling::img in order to retrieve the node list I want <img alt="1" src="file.gif"/> <img alt="2" src="file.gif"/> <img alt="3" src="file.gif"/> <img alt="4" src="file.gif"/> As it is a node list I can then iterate on the nodes to retrieve the attribute value I am looking for, but is there an XPath way of doing it? I would have expected to be able to write something like: //div[@id='marker']/preceding-sibling::img@alt or //div[@id='marker']/preceding-sibling@alt::img but I don't even know if it is possible once you have used an XPath Axe like preceding-sibling.

  • Wrapping text and div as a unit

    - by mathee
    I have the following that I would like wrapped as units. <div class='tag-box'> <a href=#>Axe Committee</a> <div class='circle'><a href=#>x</a></div> </div> The CSS for these classes are: .tag-box { display:inline; } .circle { display:inline; padding-left:4px; padding-right:4px; background:rgb(196,15,24); /*dark red*/ -moz-border-radius:10px; -webkit-border-radius:10px; } .circle a { font-size:10px; text-decoration:none; color:#fff; position:relative; top:-2px; } I can have upwards of 20 or 30 of these tag-boxes displayed inline. The problem is that the wrapping will break the words from each other or even break the red circle from the link. This makes it hard to differentiate which circle belongs to which link. (In the future, each circle corresponds to a different action with respect to the link.) See below. How do I prevent this kind of wrapping from occurring?

    I am trying to make my control lines static so instead of being displayed as part of the graph(the control lines are moving with the graph), they would be displayed like an axis the app can only scroll horizontally i'm talking about the two red line and the green line(which i put over the x axis) this is how i do my lines: // Center line CPTScatterPlot *centerLinePlot = [[CPTScatterPlot alloc] init]; centerLinePlot.identifier = kCenterLine; CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; lineStyle.lineWidth = 2.0; lineStyle.lineColor = [CPTColor greenColor]; centerLinePlot.dataLineStyle = lineStyle; centerLinePlot.dataSource = self; [graph addPlot:centerLinePlot]; but maybe it has something to do with the displayed range: ////////ajuste la portion a voir if(data.Resultats.count>10) { plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(data.Resultats.count - 10) length:CPTDecimalFromDouble(10)]; } plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(RangeMin) length:CPTDecimalFromDouble(RangeMax-RangeMin)]; // Adjust visible ranges so plot symbols along the edges are not clipped CPTMutablePlotRange *xRange = [plotSpace.xRange mutableCopy]; CPTMutablePlotRange *yRange = [plotSpace.yRange mutableCopy]; //place l'axe x sur la ligne de controle pour voir les WorkOrders x.orthogonalCoordinateDecimal = CPTDecimalFromDouble(center); //x.orthogonalCoordinateDecimal = yRange.location; //y.orthogonalCoordinateDecimal = xRange.location; //x.visibleRange = xRange; //y.visibleRange = yRange; //x.gridLinesRange = yRange; //y.gridLinesRange = xRange; [xRange expandRangeByFactor:CPTDecimalFromDouble(1.15)];//1.05 [yRange expandRangeByFactor:CPTDecimalFromDouble(1.15)]; plotSpace.xRange = xRange; plotSpace.yRange = yRange;

  • At times, you need to hire a professional.

    - by Phil Factor
    After months of increasingly demanding toil, the development team I belonged to was told that the project was to be canned and the whole team would be fired.  I’d been brought into the team as an expert in the data implications of a business re-engineering of a major financial institution. Nowadays, you’d call me a data architect, I suppose.  I’d spent a happy year being paid consultancy fees solving a succession of interesting problems until the point when the company lost is nerve, and closed the entire initiative. The IT industry was in one of its characteristic mood-swings downwards.  After the announcement, we met in the canteen. A few developers had scented the smell of death around the project already hand had been applying unsuccessfully for jobs. There was a sense of doom in the mass of dishevelled and bleary-eyed developers. After giving vent to anger and despair, talk turned to getting new employment. It was then that I perked up. I’m not an obvious choice to give advice on getting, or passing,  IT interviews. I reckon I’ve failed most of the job interviews I’ve ever attended. I once even failed an interview for a job I’d already been doing perfectly well for a year. The jobs I’ve got have mostly been from personal recommendation. Paradoxically though, from years as a manager trying to recruit good staff, I know a lot about what IT managers are looking for.  I gave an impassioned speech outlining the important factors in getting to an interview.  The most important thing, certainly in my time at work is the quality of the résumé or CV. I can’t even guess the huge number of CVs (résumés) I’ve read through, scanning for candidates worth interviewing.  Many IT Developers find it impossible to describe their  career succinctly on two sides of paper.  They leave chunks of their life out (were they in prison?), get immersed in detail, put in irrelevancies, describe what was going on at work rather than what they themselves did, exaggerate their importance, criticize their previous employers, aren’t  aware of the important aspects of a role to a potential employer, suffer from shyness and modesty,  and lack any sort of organized perspective of their work. There are many ways of failing to write a decent CV. Many developers suffer from the delusion that their worth can be recognized purely from the code that they write, and shy away from anything that seems like self-aggrandizement. No.  A resume must make a good impression, which means presenting the facts about yourself in a clear and positive way. You can’t do it yourself. Why not have your resume professionally written? A good professional CV Writer will know the qualities being looked for in a CV and interrogate you to winkle them out. Their job is to make order and sense out of a confused career, to summarize in one page a mass of detail that presents to any recruiter the information that’s wanted. To stand back and describe an accurate summary of your skills, and work-experiences dispassionately, without rancor, pity or modesty. You are no more capable of producing an objective documentation of your career than you are of taking your own appendix out.  My next recommendation was more controversial. This is to have a professional image overhaul, or makeover, followed by a professionally-taken photo portrait. I discovered this by accident. It is normal for IT professionals to face impossible deadlines and long working hours by looking more and more like something that had recently blocked a sink. Whilst working in IT, and in a state of personal dishevelment, I’d been offered the role in a high-powered amateur production of an old ex- Broadway show, purely for my singing voice. I was supposed to be the presentable star. When the production team saw me, the air was thick with tension and despair. I was dragged kicking and protesting through a succession of desperate grooming, scrubbing, dressing, dieting. I emerged feeling like “That jewelled mass of millinery, That oiled and curled Assyrian bull, Smelling of musk and of insolence.” (Tennyson Maud; A Monodrama (1855) Section v1 stanza 6) I was then photographed by a professional stage photographer.  When the photographs were delivered, I was amazed. It wasn’t me, but it looked somehow respectable, confident, trustworthy.   A while later, when the show had ended, I took the photos, and used them for work. They went with the CV to job applications. It did the trick better than I could ever imagine.  My views went down big with the developers. Old rivalries were put immediately to one side. We voted, with a show of hands, to devote our energies for the entire notice period to getting employable. We had a team sourcing the CV Writer,  a team organising the make-overs and photographer, and a third team arranging  mock interviews. A fourth team determined the best websites and agencies for recruitment, with the help of friends in the trade.  Because there were around thirty developers, we were in a good negotiating position.  Of the three CV Writers we found who lived locally, one proved exceptional. She was an ex-journalist with an eye to detail, and years of experience in manipulating language. We tried her skills out on a developer who seemed a hopeless case, and he was called to interview within a week.  I was surprised, too, how many companies were experts at image makeovers. Within the month, we all looked like those weird slick  people in the ‘Office-tagged’ stock photographs who stare keenly and interestedly at PowerPoint slides in sleek chromium-plated high-rise offices. The portraits we used still adorn the entries of many of my ex-colleagues in LinkedIn. After a months’ worth of mock interviews, and technical Q&A, our stutters, hesitations, evasions and periphrastic circumlocutions were all gone.  There is little more to relate. With the résumés or CVs, mugshots, and schooling in how to pass interviews, we’d all got new and better-paid jobs well  before our month’s notice was ended. Whilst normally, an IT team under the axe is a sad and depressed place to belong to, this wonderful group of people had proved the power of organized group action in turning the experience to advantage. It left us feeling slightly guilty that we were somehow cheating, but I guess we were merely leveling the playing-field.

  • Is it possible to call Javascript's onsubmit event programatically on a form?

    - by hoyhoy
    In Ruby on Rails, I'm attempting to update the innerHTML of a div tag using the form_remote_tag helper. This update happens whenever an associated select tag receives an onchange event. The problem is, <select onchange="this.form.submit();">; doesn't work. Nor does document.forms[0].submit(). The only way to get the onsubmit code generated in the form_remote_tag to execute is to create a hidden submit button, and invoke the click method on the button from the select tag. Here's a working ERb partial example. <% form_remote_tag :url => product_path, :update => 'content', :method => 'get' do -%> <% content_tag :div, :id => 'content' do -%> <%= select_tag :update, options_for_select([["foo", 1], ["bar", 2]]), :onchange => "this.form.commit.click" %> <%= submit_tag 'submit_button', :style => "display: none" %> <% end %> <% end %> What I want to do is something like this, but it doesn't work. <% form_remote_tag :url => product_path, :update => 'content', :method => 'get' do -%> <% content_tag :div, :id => 'content' do -%> # the following line does not work <%= select_tag :update, options_for_select([["foo", 1], ["bar", 2]]), :onchange => "this.form.onsubmit()" %> <% end %> <% end %> So, is there any way to remove the invisible submit button for this use case? There seems to be some confusion. So, let me explain. The basic problem is that submit() doesn't call the onsubmit() code rendered into the form. The actual HTML form that Rails renders from this ERb looks like this: <form action="/products/1" method="post" onsubmit="new Ajax.Updater('content', '/products/1', {asynchronous:true, evalScripts:true, method:'get', parameters:Form.serialize(this)}); return false;"> <div style="margin:0;padding:0"> <input name="authenticity_token" type="hidden" value="4eacf78eb87e9262a0b631a8a6e417e9a5957cab" /> </div> <div id="content"> <select id="update" name="update" onchange="this.form.commit.click"> <option value="1">foo</option> <option value="2">bar</option> </select> <input name="commit" style="display: none" type="submit" value="submit_button" /> </div> </form> I want to axe the invisible submit button, but using a straight form.submit appears to not work. So, I need some way to call the form's onsubmit event code. Update: Orion Edwards solution would work if there wasn't a return(false); generated by Rails. I'm not sure which is worse though, sending a phantom click to an invisible submit button or calling eval on the getAttribute('onsubmit') call after removing the return call with a javascript string replacement!

  • Why does my Ajax function returns my entire code?

    - by JDelage
    I'm playing with sample code from the book "Head first Ajax". Here are the salient pieces of code: Index.php - html piece: <body> <div id="wrapper"> <div id="thumbnailPane"> <img src="images/itemGuitar.jpg" width="301" height="105" alt="guitar" title="itemGuitar" id="itemGuitar" onclick="getDetails(this)"/> <img src="images/itemShades.jpg" alt="sunglasses" width="301" height="88" title="itemShades" id="itemShades" onclick="getDetails(this)" /> <img src="images/itemCowbell.jpg" alt="cowbell" width="301" height="126" title="itemCowbell" id="itemCowbell" onclick="getDetails(this)" /> <img src="images/itemHat.jpg" alt="hat" width="300" height="152" title="itemHat" id="itemHat" onclick="getDetails(this)" /> </div> <div id="detailsPane"> <img src="images/blank-detail.jpg" width="346" height="153" id="itemDetail" /> <div id="description"></div> </div> </div> </body> Index.php - script: function getDetails(img){ var title = img.title; request = createRequest(); if (request == null) { alert("Unable to create request"); return; } var url= "getDetails.php?ImageID=" + escape(title); request.open("GET", url, true); request.onreadystatechange = displayDetails; request.send(null); } function displayDetails() { if (request.readyState == 4) { if (request.status == 200) { detailDiv = document.getElementById("description"); detailDiv.innerHTML = request.responseText; }else{ return; } }else{ return; } request.send(null); } And Index.php: <?php $details = array ( 'itemGuitar' => "<p>Pete Townshend once played this guitar while his own axe was in the shop having bits of drumkit removed from it.</p>", 'itemShades' => "<p>Yoko Ono's sunglasses. While perhaps not valued much by Beatles fans, this pair is rumored to have been licked by John Lennon.</p>", 'itemCowbell' => "<p>Remember the famous \"more cowbell\" skit from Saturday Night Live? Well, this is the actual cowbell.</p>", 'itemHat' => "<p>Michael Jackson's hat, as worn in the \"Billie Jean\" video. Not really rock memorabilia, but it smells better than Slash's tophat.</p>" ); if (isset($_REQUEST['ImageID'])){echo $details[$_REQUEST['ImageID']];} ?> All this code does is that when someone clicks on a thumbnail, a corresponding text description appears on the page. Here is my question. I have tried to bring the getDetails.php code inside Index.php, and modify the getDetails function so that the var url be "Index.php?ImageID="... . When I do that, I get the following problem: the function does not display the snippet of text in the array, as it should. Instead it reproduces the entire code - the webpage, etc - and then at the bottom the expected snippet of text. Why is that?

  • Using inheritance and polymorphism to solve a common game problem

    - by Barry Brown
    I have two classes; let's call them Ogre and Wizard. (All fields are public to make the example easier to type in.) public class Ogre { int weight; int height; int axeLength; } public class Wizard { int age; int IQ; int height; } In each class I can create a method called, say, battle() that will determine who will win if an Ogre meets and Ogre or a Wizard meets a Wizard. Here's an example. If an Ogre meets an Ogre, the heavier one wins. But if the weight is the same, the one with the longer axe wins. public Ogre battle(Ogre o) { if (this.height > o.height) return this; else if (this.height < o.height) return o; else if (this.axeLength > o.axeLength) return this; else if (this.axeLength < o.axeLength) return o; else return this; // default case } We can make a similar method for Wizards. But what if a Wizard meets an Ogre? We could of course make a method for that, comparing, say, just the heights. public Wizard battle(Ogre o) { if (this.height > o.height) return this; else if (this.height < o.height) return o; else return this; } And we'd make a similar one for Ogres that meet Wizard. But things get out of hand if we have to add more character types to the program. This is where I get stuck. One obvious solution is to create a Character class with the common traits. Ogre and Wizard inherit from the Character and extend it to include the other traits that define each one. public class Character { int height; public Character battle(Character c) { if (this.height > c.height) return this; else if (this.height < c.height) return c; else return this; } } Is there a better way to organize the classes? I've looked at the strategy pattern and the mediator pattern, but I'm not sure how either of them (if any) could help here. My goal is to reach some kind of common battle method, so that if an Ogre meets an Ogre it uses the Ogre-vs-Ogre battle, but if an Ogre meets a Wizard, it uses a more generic one. Further, what if the characters that meet share no common traits? How can we decide who wins a battle?
