  • It's 2011 - why do I still have to use tables for email?

    - by John Isaacks
    This might seem like a rant, but I am curious. CSS replaced tables for layout a long time ago. But we still have to use tables for layout when creating rich emails. Why is this? Are there any other options? Are there really technical constraints that prevent CSS from working in an email. What are they? I can see how linked or embedded style sheets might be a problem, but not even inline styles work. Is this ever going to change?

  • How to become more productive in design and programming

    - by aurel
    Usually whenever I see tutorial videos (apart from the main subject) I learn a lot from their working habits, for example; they way they have set up their folders, what shotcuts they use. The best example was (long time a go) I say a jquery video, and half way through the author said something like “by the way you could have a code library” – that’s the only thing I remember from that video (but the author said it as something he assumed people know about) So I was wondering if someone knows any tip or any website which goes other how other professionals work, how they have set up their programming habits to help them not waste time in repetitive tasks.

  • Should I learn GWT (I'm a Java newb) if I eventually want to learn JavaScript and related libraries?

    - by Aaron
    I haven't been working with Java for a long time, and I found GWT to be interesting plus a chance to learn and practice Java. My goal for this year is to learn JavaScript. I'm very interested in HTML5, browser extensions and other cool stuff that JavaScript can do. I think I'm more interested in this than Java at the moment (that's not to say I dislike or would discontinue working with Java) but I would like advice as to whether it's a good idea to proceed with learning GWT (given my interest in JavaScript) or to spend my time learning other Java technology. Thank you.

  • Why Wikipedia doesn't appear as a referral in Google Analytics' Traffic sources?

    - by Rober
    One of my clients has a website and got not spammy backlinks in a Wikipedia article. When I test it for SEO purposes with Google Analytics (from different IPs), apparently there is no referral information. On the Real-Time view my test visit is visible but with There is no data for this view in the referrals subview. And this visits appear as (direct) / (none) on the Traffic sources view. Wikipedia is not hiding in any way its links origin, since it is shown in the server visits log. Is Google ignoring Wikipedia as a referral? Am I missing anything else? Update: Now it works, several days after the link was active. Maybe something is detecting for how long the link was there so that it doesn't work just from the beggining, as a security measure? Many visits are actually not recorded.

  • HP 655 Notebook (Ubuntu 12.04) wireless internet disabled after running updates

    - by Bastian
    Today the update-manaeger suggested that I should download some updates. So I did. After the updates were installed I had to reboot the system. After the reboot my notebook doesn't see any wireless networks. I was looking for a long time on the internet for answers but non of them applies to my case. I have the idea, it has got something to do with the kernel I am currently using (Linux 3.2.0-55). Is this one new for Ubuntu 12.04? When I boot my system I can choose to use an older kernel (linux 3.2.0-32). When I use this one the notebook does see the wireless networks. This is my network card according to the command lspci: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe Anyone an idea to fix my problems with wireless internet?

  • How do I make Unity quit opening Firefox under the Shiretoko icon?

    - by Azendale
    I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

  • Is there a media player that works on HTTPS sites?

    - by Iain Hallam
    I'm currently using Yahoo! Media Player for a site that needs to play MP3 files that are stored on our server. In total, there's quite a bit more than the free limits at Soundcloud, but each file is only a few minutes long. YMP is pretty good, but causes security warnings on HTTPS pages, because it can only be served via HTTP. Is there an equivalent free player I can embed for the HTTPS pages? EDIT: Just to clarify, I'm initially looking for something that will scan the page and turn media links playable.

  • Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 4)

    - by hinkmond
    Here's the first sign of life of a Hexbug Spider Robot converted to become a Skynet Big Data model T-1. Yes, this is T-1 the precursor to the Cyberdyne Systems T-101 (and you know where that will lead to...) It is demonstrating a heartbeat using a simple Java SE Embedded program to drive it. See: Skynet Model T-1 Heartbeat It's alive!!! Well, almost alive. At least there's a pulse. We'll program more to its actions next, and then finally connect it to Skynet Big Data to do more advanced stuff, like hunt for Sara Connor. Java SE Embedded programming makes it simple to create the first model in the long line of T-XXX robots to take on the world. Raspberry Pi makes connecting it all together on one simple device, easy. Next post, I'll show how the wires are connected to drive the T-1 robot. Hinkmond

  • Wide gap in my resume as a Java developer. What are must-have skills required to get hired those days? [closed]

    - by OnlineAlien
    For some legal reasons I haven't worked for anybody for the last 12 years. I am a java web developer or at least I am thinking so. For this period I have been working on my project- some sort of business network - and I did few small jobs, so right now I feel I am far behind in terms of my skills and the skills needed today. I lingered too long on Struts and Hibernate and thought that could the job for my project. I need to get a job, right now, so I am spending most of my time brushing my skills. My question is: What are the current necessary skills that could convince employers to hire me regardless of my past employment or the lack of it. Right now I am on AspectJ, IoC and Spring Thanks

  • Infinite redirect loop in cpanel-purchased script

    - by lital maatuk
    I am installing a script (that I bought on cpanel) in the root directory of my web site. When I try to install it, it gives me an error. I found that it starts an infinite URL redirect loop containing the name of my web site. Something like: install//mywebsite.com/install=mywebsite.com/install=mywebsite.com/install=mywebsite.com etc. until the browser refuses to continue when URL gets too long. The vendor told me I need to have mod_rewrite installed on my cpanel and something about .htaccess. How do I do fix this?

  • How to determine the right amount of up front design?

    - by Gian
    Software developers occasionally are called upon to write fairly complex bits of software under tight deadlines. Often, it seems like the quickest thing to do is to simply start coding, and solve the problems as they arise. However, this approach can come back to bite you—often costing time or money in the long run! How do we determine the right amount of up front design work? If your work environment actively discourages you from thinking about things up front, how do you handle that? How can we manage risk if we eschew up-front thinking (by choice or under duress) and figure out the problems as they arise? Does the amount of up front design depend entirely on the size or complexity of the task, or is it based on something else?

  • Test Doubles : Do they go in "source packages" or "test packages"?

    - by sbrattla
    I've got a couple of data access objects (DefaultPersonServices.class, DefaultAddressServices.class) which is responsible for various CRUD operations in a database. A few different classes use these services, but as the services requires that a connection is established with a database I can't really use them in unit tests as they take too long. Thus, I'd like to create a test doubles for them and simply do FakePersonServices.class and FakeAddressService.class implementations which I can use throughout testing. Now, this is all good (I assume)...but my question relates to where I put the test doubles. Should I keep them along with the default implementations (aka "real" implementations) or should I keep them in a corresponding test package. The default implementations are found in Source Packages : com.company.data.services. Should I keep the test doubles here too, or should the test doubles rather be in Test Packages : com.company.data.services?

  • What options should I consider for a modern Web/Mobile development stack? [on hold]

    - by jimmy_terra
    I'm a long time server side dev who has been tasked with building a bleeding edge web UI (go figure), so apologies for the very broad nature of the question. What are the best modern libraries, tools, languages and patterns for building a dynamic web application that will run seamlessly on mobiles also? My requirements are that it must be dynamic (push updates), support automated testing, and should allow 'componentization' (a team of devs will be working on this). What should I check out and why? I will start off with some of the things I'm looking at already: Front-end HTML5 CSS3 JavaScript AngularJs Testing Karma Testem Jasmine Patterns Single Page Applications

  • Queuing rpc calls

    - by alfa64
    i'm designing a system wich listen to json rpc calls from clients, piles it up inside a list, and if it gets full it should store them in a DB and keep recieving calls. My original plan is to listen to the rpc calls from Perl with the json-rpc and put them in the array. The clients do some long polling in another server to get responses as they appear. What is this blocking/noblocking thing? Should i do a script for node.js to listen to the calls? What do you think is a good practice in this case? The objective is to listen as much calls as possible.

  • Should a developer always use version control

    - by kurtnelle
    I've heard statements to the effect of: "Well it's just me working on this project so I don't need to put it under source control" as well as, "There is no need to work version controlled on this project, it's so small". It is my opinion that no matter how small the project is, so long as it's adding value to the client (and they are paying for it too) that we, the developer(s), should version control it; especially since its company policy. Am I insane or does my standpoint make sense. Question: Should development work always be version controlled?

  • Anyone code at a treadmill desk? [closed]

    - by Sequenzia
    have been thinking about getting a treadmill desk for awhile now but I just don't know if it is possible to code at one. I can see doing a normal computer job while walking very slow but I just don't know if you can write code do it. Like a lot of people I could stand to lose weight and I am just not in shape anymore. I sit at my computer for at least 12 hours a day and then I am on my laptop for a few more hours. I need to do something to help my health. I also have been seeing a lot of reports about the long term health issues related to desk jobs. Like this. Before I drop a few hundred dollars on a new desk I am wondering if anyone has tried a treadmill desk and if so which one?

  • Alternative to | more to display error results page by page

    - by Lane
    The command psql -d template_postgis2 -f /usr/share/postgresql/9.1/contrib/postgis-2.1/postgis.sql returns a list of errors that is too long to be displayed by scrolling up to the beginning of the error. I tried the same command with "| more" and "| less" added up at the end of the command but it does not display the message page by page as it should. I also tried to put the output in a file with "> file.txt" but I do not get in this new file what is displayed on the screen!! I don't understand why. I guess i can't do this with a psql command?? Is there any other way to get all the error message? Thanks for your help!

  • 12.04 server on home network

    - by dustin mantei
    I need advice to help me with a server install, I'm new to ubuntu and linux in general. I have 6 systems in my house, 5 being windows 7 and this laptop that I am typing on is Linux mint 13 Maya. Question is, my wife will not transition to anything. She is stuck in Gates-land. so, can I make a server with ubuntu 12.04 (burnt disc image last night) so that all systems in my home can access and my mother-in-law in another state can also access with a username? That would be awesome and it may convince the war dept (my wife) to change all the systems in my house to ubuntu/linux. Sorry this is so long winded, but all the questions I have seen on this forum don't answer it completely.

  • Swap is not copied back into physical memory

    - by GradGuy
    I have a question regarding swap and physical memory. Often times I run a program that requires a lot of memory and as a result I can see some of the data is copied from the physical memory into swap. However, once the program is terminated, and the physical memory is freed I can still see a considerable amount of data on swap which significantly slows down the system and is annoying! What is the reason behind this and how does the OS decide which part of data should go to swap? How long is this data supposed to be there and how is it "freed"?

    - by alexismp
    It's time for me (Alexis) to move to new challenges and this 773rd post of mine on TheAquarium will be my last one. For all these years since TheAquarium was started by others, this place has seen the community come to life, grow and thrive. It has been an effective way for the GlassFish team to share our progress and for you the community to provide feedback, both good and not so good. Thank you for your continued readership, support and feedback, all of which contributed to keep TheAquarium the #1 technical blog at Oracle and helped us improve Java EE and GlassFish in a significant way. Oracle has exciting and ambitious plans for GlassFish 4.0 and Java EE 7 and I trust TheAquarium will remain an important link in the chain as both of these are being delivered. I leave you in the hands of savvy and sharp contributors. Long live The Aquarium! - AlexisMP

  • Developing an AI opponent for Monopoly

    - by Bernhard Zürn
    i want to develop an AI opponent for the Board Game Monopoly. I want to implement the whole Game with Prolog (XPCE). The probability for a field on the Board being hit, can be computed with Markov Chains. I already know some "best practices" like "after 50% of the playing time it does not make sense to buy out of jail because in jail you get renting fees for your fields but you don't have to pay for other fields as long as you stay in prison". The interesting question always is: buy a streetfield ? buy houses / hotels ? how much ? so i think i would have to compute some kind of future liquidity .. does anyone know how to pack that into an algorithm or how to translate it to prolog ?

  • OOW 2012: Slides Download

    - by Mike Dietrich
    Hm ... you might ask yourself why there are no Oracle Database 12c slides available for download, neither in the OOW 2012 content system nor on our blog (and I believe nowhere else). Simple reason: As long as Oracle Database 12c is not released and available we are not allowed to offer slides for download. Therefore people were simply taking pictures during the 12c sessions with their phones, iPods and cameras. Roy took a nice shot: Sorry for that - we'll make the content available as soon as Oracle Database 12c gets released. In between you can download our OOW 2012 talk Database Upgrades on Steroids: Real Speed, Real Customers, Real Secrets as PDF (3.4MB) - but the 12c content is currently not in that PDF. But a lot of information applies to your source database and/or to any upgrade - so it still might be helpful. And unfortunately the same 12c rule applies to the slides guiding you through our Hands-On-Lab on Tuesday. Thanks
