  • Super simple CSS tooltip in a table, why is it not displaying and can I make it work?

    - by Kyle Sevenoaks
    Hi, I have been trying to implement many different tooltips on this page for my client, he's adamant that we have a picture of the product show up when you hover over the product name in the order page. I decided to use the super simple CSS tooltip, it's very easy to implement and does exactly what we want. It works on a dynamic page, the others I tried didn't. I have made an example here: CSS tooltip in table example. This page used to be displayed using divs, I have since changed it to a table, as it's tabular data and easier to work with. It worked fine when it used divs, now it's in a table, it won't display the span on hover. My questions are: Why is it not working? How can I make it work? If not, does anyone know another super easy to implement tooltip that can work properly on a dynamic page? Here's the DIV tooltip for reference: DIV display tooltip. Edit: Just noticed it kinda half works in IE8. Thanks.

  • What is the best degree Computer Engineering or Software Engineering?

    - by Samourainite
    I'm interested in getting into the gaming industry, but i'm unsure as to whether which degree would help me the most. I also do not have any prior programming knowledge(apart from some basic html). So, do you guys have any opinion on which degree i should pick? please don't mention anything about game development or games programming degrees. You may also compare the 2 degrees with Computer Science degree.

  • Why do camera's aspect ratio look good on computer but not on Android devices?

    - by Pooya Fayyaz
    I'm developing a game for Android devices and I have a script that solves the aspect-ratio problem for computer screens but not for my intended target platform. It looks perfect on computer, even when re-sizing the game screen, but not when running my game in landscape mode on mobile phones. This is my script using UnityEngine; using System.Collections; using System.Collections.Generic; public class reso : MonoBehaviour { void Update() { // set the desired aspect ratio (the values in this example are // hard-coded for 16:9, but you could make them into public // variables instead so you can set them at design time) float targetaspect = 16.0f / 9.0f; // determine the game window's current aspect ratio float windowaspect = (float)Screen.width / (float)Screen.height; // current viewport height should be scaled by this amount float scaleheight = windowaspect / targetaspect; // obtain camera component so we can modify its viewport Camera camera = GetComponent<Camera>(); // if scaled height is less than current height, add letterbox if (scaleheight < 1.0f && Screen.width <= 490 ) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } else // add pillarbox { float scalewidth = 1.0f / scaleheight; Rect rect = camera.rect; rect.width = scalewidth; rect.height = 1.0f; rect.x = (1.0f - scalewidth) / 2.0f; rect.y = 0; camera.rect = rect; } } } I figured that my problem occurs in this part of the script: if (scaleheight < 1.0f) { Rect rect = camera.rect; rect.width = 1.0f; rect.height = scaleheight; rect.x = 0; rect.y = (1.0f - scaleheight) / 2.0f; camera.rect = rect; } Its look like this on my mobile phone (portrait): and on landscape mode:

  • prevent schemagen from adding the super-class to the schema?

    - by shay
    Hi, how do i prevent schemagen from adding the super-class to the schema? I have tried using XMLTransient on the super-class, and on its fields but they still show up in the schema . for example : @XmlTransient public class Asset { @XmlTransient public Long ID; } public class Movie extends Asset { } creates this schema : <xs:complexType name="asset"> <xs:sequence> <xs:element name="ID" type="xs:long" minOccurs="0"/> </xs:sequence> </xs:complexType> <xs:complexType name="movie"> <xs:complexContent> <xs:extension base="asset"> <xs:sequence/> </xs:extension> </xs:complexContent> </xs:complexType> the schema that i would like to see is : <xs:complexType name="movie"> <xs:complexContent> <xs:sequence/> </xs:extension> </xs:complexContent> </xs:complexType>

  • Is it wrong to tell mobile users to view a site on their computer?

    - by betamax
    I am creating a web application that doesn't work correctly on mobile. I don't want to make it work on mobile because I would rather mobile users have a fully integrated experience and not have to use the web version. This mobile version will be released at a later date based on reaction to the initial web-based version. So, my question is: Is it wrong to not allow mobile users to use the site and instead show them some sort of splash screen telling them to come back to the site on a computer?

  • I'm graduating with a Computer Science degree but I don't feel like I know how to program.

    - by wp123
    I'm graduating with a Computer Science degree but I see websites like Stack Overflow and search engines like Google and don't know where I'd even begin to write something like that. During one summer I did have the opportunity to work as a iPhone developer, but I felt like I was mostly gluing together libraries that other people had written with little understanding of the mechanics happening beneath the hood. I'm trying to improve my knowledge by studying algorithms, but it is a long and painful process. I find algorithms difficult and at the rate I am learning a decade will have passed before I will master the material in the book. Given my current situation, I've spent a month looking for work but my skills (C, Python, Objective-C) are relatively shallow and are not so desirable in the local market, where C#, Java, and web development are much higher in demand. That is not to say that C and Python opportunities do not exist but they tend to demand 3+ years of experience I do not have. My GPA is OK (3.0) but it's not high enough to apply to the large companies like IBM or return for graduate studies. Basically I'm graduating with a Computer Science degree but I don't feel like I've learned how to program. I thought that joining a company and programming full-time would give me a chance to develop my skills and learn from those more experienced than myself, but I'm struggling to find work and am starting to get really frustrated. I am going to cast my net wider and look beyond the city I've grown up in, but what have other people in similar situation tried to do? I've worked hard but don't have the confidence to go out on my own and write my own app. (That is, become an indie developer in the iPhone app market.) If nothing turns up I will need to consider upgrading and learning more popular skills or try something marginally related like IT, but given all the effort I've put in that feels like copping out. EDIT: Thank you for all the advice. I think I was premature because of unrealistic expectations but the comments have given me a dose of reality. I will persevere and continue to code. I have a project in mind, although well beyond my current capabilities it will challenge me to hone my craft and prove my worth to myself (and potential employers). Had I known there was a career overflow I would have posted there instead. Thanks again!

  • Javascript inheritance: call super-constructor or use prototype chain?

    - by Jeremy S.
    Hi folks, quite recently I read about javascript call usage in MDC https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/call one linke of the example shown below, I still don't understand. Why are they using inheritance here like this Prod_dept.prototype = new Product(); is this necessary? Because there is a call to the super-constructor in Prod_dept() anyway, like this Product.call is this just out of common behaviour? When is it better to use call for the super-constructor or use the prototype chain? function Product(name, value){ this.name = name; if(value >= 1000) this.value = 999; else this.value = value; } function Prod_dept(name, value, dept){ this.dept = dept; Product.call(this, name, value); } Prod_dept.prototype = new Product(); // since 5 is less than 1000, value is set cheese = new Prod_dept("feta", 5, "food"); // since 5000 is above 1000, value will be 999 car = new Prod_dept("honda", 5000, "auto"); Thanks for making things clearer

  • NAT ports - how do they work?

    - by Davidoper
    I have the following network schema: Computer A: three nics: NIC 1 (eth0): dhcp, public internet NIC 2 (eth1): static 192.168.1.1, gateway for Computer B NIC 3 (eth2): static 192.168.2.1, gateway for Computer C Computer B: static 192.168.1.2, using gateway 192.168.1.1 (NIC 2). Computer C: static 192.168.2.2, using gateway 192.168.2.1 (NIC 3). So I applied this to get NAT working: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE Every computer can connect to the internet now. I have been applying rules to the main computer (Computer A), like dropping connections to some ports, e.g ssh: iptables -A INPUT -p tcp --dport 22 -j DROP But for instance, now I would like only allow connections for ports 20,21,22,53 and 80 in Computer C, and ignore the outside traffic if it's not related to those ports. The allowed connections should be FROM Computer C to outside, but not from outside to Computer C (I mean - Computer C is not hosting any HTTP or SSH, but it is going to use them as a client). I guess this sould be done like this: iptables -A OUTPUT -i eth2 -o eth0 -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT iptables -A INPUT -i eth2 -o eth0 -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT The last rule (dropping any other traffic different from those) is at the end of the configuration, so -A should be working correctly. The thing is... it is not working. If I put the last rule like this: iptables -A FORWARD -i eth2 -o eth0 -j DROP It just drops everything and, for instance, port 21 (previously opened as you can see above) is not either working. Can you tell me what could I have done wrong? I have been struggling with this problem for some time and I am unable to solve it. Thanks!

  • ssh key questions

    - by Tim
    I have some questions regarding generating keys for ssh access: (1) Supposed there are two computers running ssh server service and I have generated a pair of key files on computer A and copy the public file to computer B. Is it true that this is only a one-way key: We only gave computer A permission to access computer B, not gave computer B permission to access computer A? If I now want to ssh from computer B to computer A, must I generat another pair of key files on computer B and copy the public file to computer A? (2) If I would like to connect a single local computer to several remote servers, is it to generate a common pair of key files only once on the local and copy the same public file to the remote servers, or to generate different pair of key files on the local for different remote servers? (3) If I would like to connect several local computers to a single remote server, when copying the public files from different local computers to the remote server, is it to combine them together into a single authorized_keys file or store them in different authorized_keys files? (4) If there are several servers shared the same file system by, for example, NFS, how to generate keys and arrange the key files for accessing from one server to the other? Also how to still generate keys and arrange the key files for a local computer to access anyone of the servers? All the machines above are Linux.Please provide examples and commands in your reply so that I can better understand how to solve the problems. Thanks and regards!

  • Which browser does my computer use to open a Web page? [on hold]

    - by msh210
    I know little about networking the Internet, but, from what I understand, it works — very approximately — as follows: I, sitting at the computer example.com, send a message saying, roughly, "get http://s.tk" to my ISP, which passes the message along, eventually to the machine at s.tk. The s.tk machine gets "example.comhas sent 'gethttp://s.tk'", so sendssomefileto its ISP which passes the file along, eventually to the machine atexample.com`. When the file gets back to example.com, my computer, how does my computer know what to do with it? I'm sure the headers (or something else) indicate it's a Web page rather than, say, a Usenet post — that's not my question. My question is: how does it know whether to display the Web page in my open Opera window or my open Firefox window, or my other open Firefox window, or, heck, to open a new browser instance?

  • Computers "applying computer settings" for a long time on start-up...why?

    - by tombull89
    Hello. Might be a bit of a slong shot but I'm stumped, along with the ICT Manager for the school I'm working it. In one of the IT rooms when you switch a computer on it will boot through BIOS fine, but when it gets to "applying computer settings" it can hang for a long time (~15 minutes). If you unplug the computer from the network it starts up fine, gets to the login screen, then you can plug the network cable in and it will work fine. I don't think it's anything to do with the fact we've been coming close to running out of IP addresses or a problem with our DHCP. Microsoft KB says apply the latest service pack, which we've done, and check a service. Servers and domian controllers are S2003, Computers and Desktops are XP. Does anybody have any thoughts on what to try?

  • Blocking ICMP outgoing requests only in eth1

    - by Raj
    I am creating a NAT with iptables: Computer A: eth0 (dhcp) + eth1 (static ip 192.168.0.1 - gateway) Computer B: eth1 (static ip 192.168.0.2, using Computer A as gateway) I know how to block ICMP outgoing requests (-A OUTPUT -p icmp --icmp-type echo-request -j DROP), but that would block ICMP requests from Computer A, but not from Computer B (in fact, only for Computer A - Computer B can keep doing those). I tried with the same command, but adding -o eth1, but that does not block at all. Any idea?

  • The Art of Computer Programming - To read or not to read?

    - by Zannjaminderson
    There are lots of books about programming out there, and it seems Code Complete is pretty much at the top of most people's list of "must-read programming books", but what about The Art of Computer Programming by Donald Knuth? I'm a busy person, between work and a young family I don't have a ton of free time, so I have to be picky about how I use it. I'm wondering - has anybody here read 'TAOCP'? If so, is it worth making time to read or would some other book or more on-the-side programming like pet projects or contributing to open source be a better use of my time in terms of professional development? DISCLAIMER - For those of you who sport "Knuth is my homeboy" t-shirts, don't get me wrong - I want to read it, but I'm just wondering if it should be right at the top of my priority list or if something else should come first.

  • Can we set up svn server on a local computer without any network access?

    - by Aitezaz Abdullah
    I want to set up an SVN repository on my computer without any network access. I am working on a code without any collaborator, so I don't want it to be publicly available. I read the following post. http://stackoverflow.com/questions/6001445/local-source-control-repository-cross-platform but this post suggests using online svn repository services that give free repositories. In that case, my code will be publicly available (as is included in the terms of free plans). So I was wondering if I can set up a local server on my windows xp machine that only I access even when I don't have any internet connection?

  • How can a computer render a CLI/console along with a GUI?

    - by Nathaniel Bennett
    I'm confused when looking into graphics - specifically with operating systems. I mean, how can a computer render a CLI/console along with a GUI? GUI's are completely different from text. And how can we have GUI windows that display text interfaces, ie how can we have CLI in modern Graphics Operating system - that's what I'm mainly trying to grip on to. How does graphics get rendered to display? Is there some sort of memory address that a GPU access which holds all pixel data, and there system's within OS's that gather the pixel position of windows and widgets, along with the Z Index and rasterize them to that memory address, which then the GPU loads to the screen? How about the CLI's integrated with Graphics? How does the OS tell the GPU that a certain part of the screen wants to display text while the rest wants to display pixel data?

  • How important is Discrete Mathematics for a Computer Scientist?

    - by mort
    As the title says, How important is Discrete Mathematics for a Computer Scientist? Background: I'm pursuing a Master's degree with a focus on fundamentals such as Algorithms, Complexity and Computability Theory and Programming Languages to get a good foundation for working in the field of Parallel Computing. Some more background: My university grants a lot of freedom in the choices of courses for my Master's degree. It's officially called "Software Engineering", but due to a the broad range of electives, a different focus is possible. Interestingly, none of the electives is a lecture in Math! I'm thinking about doing a course about Discrete Mathematics that would take half a semester to complete successfully, even if I can't use it for my degree. So with this question I'm trying to find out if the effort is justifiable.
