• 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.

• Efficient way to check for changes to the contents of folders

  - by MrVimes

  I am creating an application that maintains a database of files of a certain type in a given folder (and all subfolders) Initially the program will recurse the folders and add any file it finds of that type to the database. I want the application to have the ability to re-scan the folder and add any files that were not there the last time the folders were scanned. It can't use the date created property of the file because there is a high chance of a file being added to the folders that isn't a new file. I am wondering what the most efficient way of doing this is, and if there is a way that doesn't involve checking each file is in the database already (which, if there are 5000 files would mean 5000 queries of a list 5000 items in size, or 25 million 'checks' for the sql engine to perform) I suppose a more specific question to acheive the same goal would be - is there a property of a file (in Microsoft Windows) that will reliably tell you when that file arrived in that folder.

• Why is (Ogg) Vorbis not automatically supported by Windows?

  - by flying sheep

  Vorbis was never threatened by MPEG LA, so it is undoubtedly completely patent free. (MPEG LA never misses a chance to spread patent FUD) Windows supports mp3, so it isn’t because they want to push their crappy wma. The GPL allows distribution alongside commercial products, and Even if they fear to ship GPL software, they can still load it automatically, like they do with XviD So why can’t a windows customer not simply drop a ogg vorbis file into his/her music library and listen to it via WMP? PS: To counter misconceptions: They already download the GPL’d XviD codec on demand, so they already have 99% of what it takes to do the same with Vorbis. It would take me about 5 minutes to do this, if I were familiar with the WMP code base and directshow filter system. PSS: I was told to ask this here rather than on stackoverflow, so i do.

• How To Track "Similar Product/Page" Links In Internal Site

  - by Petra Barus

  So I just created a new widget that would show up in a product page in my site. This widget will show several products similar to the product that is displayed in the current page. The purpose is to help users compare similar products. Let's say in the product page A http://domain/products/A The Similar Products widget will show http://domain/products/B http://domain/products/C http://domain/products/D http://domain/products/E My question is how to track this "Product B page were visited X times from Product A page via Similar Product widget"? (And there is also chance that Product B will show up in the widget on Product C page) I have this idea using the Event feature from Google Analytics. But I'm still not sure if it is or what is the common best practice for this.

• Update installed on netbook.. now sidebar icons have disappeared! :oS

  - by Lolly Collier

  hope someone can help. I am not extremely computer literate and my brother installed Ubuntu on my Acer net book when my windows crashed irretrievably . I recently (day before yesterday) had a box come up saying an update (i think it was 10 or 11 .something) i followed the instructions to download and install it and now, all my side bar icons have disappeared. I happened upon an Internet connection by chance and have no idea whatsoever how to get them back. This is quite probably a really stupid question and a really easy fix but as i said earlier, i am pretty much a novice, very far from a computer expert! Thanx in advance :o)

• Boots to a totally blank screen after I installed some ATI Radeon card updates

  - by baboonWorksFine

  I am using Ubuntu 10.04 LTS, dual boot with win7 on ThinkPad T400, I followed Ubuntu update hints and installed some update for my ATI Radeon graphic card, but when I boot to Ubuntu(means I can still load GRUB), the tragedy happened, the screen goes to blank and no matter what key stroke, I can not get any responds, I try to go to text terminal, but impossible! However when I hit the power button, the computer would pop out the Ubuntu shutdown screen briefly and shut down. I figure out I should delete the updates package of my graphic card, but I don't even get a chance to go to text terminal, please help me!

• Career Shifters: How to compete with IT/ComSci graduates

  - by CareerShifter

  I am wondering what are the chances of a career shifter (mid 20's), who have maybe 3-6 months programming experience vs. younger fresh IT/Com Sci graduates. You see, even though I really love programming (Java/J2EE), but nobody gives me a feedback when I apply online. maybe because they preferred IT/ComSci graduates vs a career shifter like me.. So can you advice on how to improve my chance on being hired. How can i get a real-job programming experince if nobody is hiring me. I can make my own projects (working e-commerce site blah blah) but it is still different from the real job. And my codes are working but it still needs a lot of improvement and no one can tell me how to improve it because no one sees it (because I'm doing it alone?). Do you know any open source websites (java/j2ee/jee) / online home-based jobs who accepts java/j2ee/jee trainees.. Thank you very much

• April 25th Online Forum -- Oracle Solaris 11: What's New Since the Launch

  - by Larry Wake

  It's been a few months since we released Oracle Solaris 11, so we thought it was time to check in and let you know how things are going. On April 25th, at 9:00 PT, we'll host an online forum, featuring Markus Flierl, the VP for Solaris core engineering, as well as engineers, customers and partners. During the forum, Markus and his crew will give an update on the release, recap Oracle's OS strategy, and give you a peek at what the engineers are working on for future updates. I think one of the more interesting parts of this event will be the chance for some of our customers to share why they've moved to Oracle Solaris 11 and what benefits it has already given them.  We'll also have an online chat, so you can ask Solaris engineers any questions about what you've heard, or other thoughts you've had.  It should be a worthwhile event -- hope you can join us. Online Forum: Oracle Solaris 11: What’s New Since the LaunchApril 25th 9:00 a.m. PDT – 11:30 a.m. PDTRegister today!

• Why does the Git community seem to ignore side-by-side diffs

  - by Kyle Heironimus

  I used to use Windows, SVN, Tortoise SVN, and Beyond Compare. It was a great combination for doing code reviews. Now I use OSX and Git. I've managed to kludge together a bash script along with Gitx and DiffMerge to come up with a barely acceptable solution. I've muddled along with this setup, and similar ones, for over a year. I've also tried using the Github diff viewer and the Gitx diff viewer, so it's not like I've not given them a chance. There are so many smart people doing great stuff with Git. Why not the side-by-side diff with the option of seeing the entire file? With people who have used both, I've never heard of anyone that likes the single +/- view better, at least for more than a quick check.

• Best options for freelance or part-time programming? [closed]

  - by Andrew

  I apologize in advance if this is an inappropriate question for this SE. A few years back I was all set to study computer science and get a job programming, but went a totally different route and went into healthcare. I currently work as a paramedic on a rotating 24/48 schedule, so I have two days off for every day I work, and a decent bit of downtime on the days that I do work. I've been looking at ways to earn some extra money with all that spare time, and was wondering if it'd be worth the effort to try and find a part-time/freelance gig. I know HTML/CSS, PHP, and I'm pretty familiar with Python and Ruby (and Rails). Anyways, was hoping that someone could point me in the right direction as what "skill set" would give me the best chance to be able to land a part-time/freelance gig. I realize this is a rather open-ended question but any direction is appreciated.

• How to remove shells?

  - by MyNameIs...

  I installed few shells that I wanted to try out on Ubuntu 12.04, but none of them worked at all. It could be that I installed them all at the same time, meaning the OS didn't get a chance to work everything out, but either way, they didn't work. I would now like to remove them. The one's that I installed are Fluxbox, OpenBox, XFCE, and MATE. I installed them through the help of this site. Everything seemed to have been working properly until I actually tried to use the shells and nothing loaded at all. Except for Fluxbox, I think that one worked. I want to know of any way to repair or perhaps just remove the packages entirely. I might have already removed them because I did the apt-get remove command on all of them, but they were still in the list on the login screen.

• My website links now include DirectX categories

  - by Michael B. McLaughlin

  I’ve done a bit of overdue updates to my website. The links page - http://www.bobtacoindustries.com/Developers/Links  - now includes DirectX links. I’ve also updated all of the links that were broken in the recent changes to the App Hub site. If you have any good links you think I’m missing, let me know. I haven’t had a chance to do any dead link checking & pruning yet so there might be some links that go to the wrong place or go nowhere at all. That’s the problem with link repositories; maintenance of them is quite a bit of work. But hopefully I’ll find some time to do that soon.

• How do I check that my tests were not removed by other developers?

  - by parxier

  I've just came across an interesting collaborative coding issue at work. I've written some unit/functional/integration tests and implemented new functionality into application that's got ~20 developers working on it. All tests passed and I checked in the code. Next day I updated my project and noticed (by chance) that some of my test methods were deleted by other developers (merging problems on their end). New application code was not touched. How can I detect such problem automatically? I mean, I write tests to automatically check that my code still works (or was not deleted), how do I do the same for tests? We're using Java, JUnit, Selenium, SVN and Hudson CI if it matters.

• Connecting a reliance zte AC2737 netconnect + modem

  - by coditor

  I have a Reliance netconnect+ zte Ac2737. It has an allocated data of 5gb per month. The modem works fine only after the allocated data is over, for which i have to pay extra to the provider. I tried contacting the provider, but it was not of much help. The system detects the modem every time. I assume that it must be a possible problem with the provider, so is there any chance it is the problem of Ubuntu 12.04 LTS 64 bit itself as i have no other reason to think otherwise an it works fine every time on windows.

• Install/running ubuntu on extarnal HDD with a windows laptop?

  - by Peter

  Sorry for asking, especially as I've trawled through many similar questions. Mine is of the most basic element I think as this kind of thing is really out of my ball park. Anyway I wanted to if by installing ubuntu on my old laptop hdd (I now use it as external storage), can I run it on my laptop which has windows installed. I can't take the chance of installing on the laptop as I'm currently studying, and I have a years worth of work on here (most backed up elsewhere), and will be using it a lot. However there are some programmes I can use if I can get ubuntu that will be helpful for one or two classes. Sorry for the very basic question.

• Working with Primary Keys and Generators - Quickstart with NHibernate (Part 4)

  - by BobPalmer

  In this NHibernate tutorial, I'll be digging into the ID tag and Generator classes.  I had originally planned on finishing up a series on relationships (parent/child, etc.) but felt this would be an interesting topic for folks, and I also wanted to start integrating some of the current NHibernate reference. Since this article also includes some reference sections (and since I have not had a chance to check for every possible parameter value), I used the current reference as a baseline, and would welcome any feedback or technical updates that I can incorporate. You can find the entire article up on Google Docs at this link: http://docs.google.com/Doc?id=dg3z7qxv_24f3ch2rf7 As always, feedback, suggestions, and technical corrections are greatly appreciated! Enjoy! - Bob

• Vmware 3D Acceleration Ubuntu 14.04

  - by Bowser5543

  I have installed Vmware Player 6.0.3 build-1895310. The problem I have is that when I run a Windows 7 Vm, it says that 3D support was disabled. (I can't read the exact report atm because it has a chance of crashing my machine.) I have the 3D support box enabled. Here is my graphics card: Mobile Intel® GM45 Express Chipset x86/MMX/SSE2. Can anyone tell me to install drivers or something? I can't find mine anywhere!

• Canon MP280 All in One prints but scanner not recognized

  - by Chris

  I recently installed Ubuntu 12.04 LTS after not using any Linux distro for several years. My Canon MP280 worked perfectly as far as printing goes and I was even able to set it up on a Samba share and print from a Windows 7 machine. However when I open Simple Scan it does not detect a scanner. I did find some instructions online but the scanner is still not recognized in Simple Scan even after installing a couple .deb packages from the Canon site. I also couldn't seem to find the ScanGear package after installing those .deb packages as well but I haven't had a chance to delve fully into it. Thanks for your time!

• What are my options for Web 2.0 gallery software?

  - by NewProger

  Good day everyone! This is my first post on this site ^_^ My question is: What are my options if I need a Web 2.0 gallery software that work in a very similar manner to this removed web site. Essentially: users can create account, then create and manage their own galleries. And all other users and guests can see these galleries, add tags, comments, etc. Basically a community driven gallery web site. When it comes to "normal" cms I know a lot of good options, but I never worked with any gallery management software... If you can suggest me some good solutions (free) it would be great! Also: If you by any chance know what software is used at this removed website it would be even better, because this solution suits me the best and I would have used this engine, but I cant find any information on what this engine is and if it is even public, or privately developed thing. Thanks in advance!

• Deferring questions about salary expectations until the second interview [closed]

  - by Polynomial

  I usually find that interviewers ask about expected salary on a first interview, but I usually feel uncomfortable discussing such details at an early stage. I feel that low-balling a figure might result in under-selling myself, whereas going too high might lose me the chance of a second interview. I also like time to reflect on my interview experience before vocalising my expectations. I recently realised that in one interview I prefixed my salary figure with a justification, which made me come across as a little desperate and unsure of myself. Is there a good way to defer such questions until a second interview (assuming I get one, of course) without hurting my chances or weakening my position?

• Mobile Application development - get hands on at UKOUG

  - by Grant Ronald

  Development of mobile solutions is one of the hottest topics in the IT market at the moment.  Forbes predicts that mobile application development with outstrip native PC development by 4-1 by 2015.  I'm therefor delighted to announce that the UKOUG and Oracle have synch'd up to provide a rolling 3 day hands-on Mobile development lab at the UKOUG conference this year. We're setting up a lab of 10 Mac machines in which you will be able to develop iOS on-device applications.  And the great thing is, if you want to develop for Android, its the same lab as well!  Just think, write once and deploy to iOS or Android.  We know places will be limited so we are going to be putting in place a first-come-first-served booking system.  Walk-ups will be allowed only if places are free. This is your chance to start skilling up on the hottest development initiative in years.

Temperature of my i7-hp pavilion dv6 rises from 67degrees to a superhot 85+ and also to 106degrees where my laptop shuts down. When running torrents or Chromium I hardly open 4 Tabs so there is no chance for CPU over-loading due to multiple processes.NEED HELP.And Thank You for your time.

• Do you think that in the future it'll be possible to develop games on OS X by using Python and the latest library "Sprite kit" made by Apple? [on hold]

  - by Cesco

  I don't understand a lot about game engines and modules for Python, even though I'm aware of the existance of PyGame and Pyglets, so please don't bash me too hard if I'll wrote something wrong in this question :-) When I upgraded my Mac to the latest version of OS X, I noticed for the first time that Apple is providing a library named Sprite kit for developing games on both iOS and OS X. It looks to me fairly complete, and the fact is managed by a big company gives me the impression of being well-supported for the time being; in summary, it looks... cool. Actually in order to take advantage of "Sprite kit" you need to code in Obj-C. Since I don't know Obj-C but only a little bit of Python, do you think that there's a chance that sooner or later someone will make a wrapper for Python ? Thank you very much and best regards
