• How do I get Ubuntu One on Win7 to authenticate my login?

  - by Fred jones

  I just got a new computer running Windows 7 home premium, I used to have Ubuntu One working great on my Ubuntu desktop, but now, running win7, I know my login email address and password is correct, but it still says 'Authentication failed'. Googling the problem, looks like it may be because a device was removed from my list of devices, but the only device listed is my previous Ubuntu workstation, and nothing has been removed. I also checked the windows firewall and Ubuntu One is allowed on all interfaces on incoming and outgoing, and still authentication fails. Web login to my Ubuntu One account works fine.

• What is the benefit of the "download will begin shortly" page?

  - by Fammy

  I've noticed many websites that host files for downloads have an interstitial page between the download link/button and the actual start of the download. Terminology on the page may include "Your download will begin shortly. If it does not, try this direct link". What is the purpose of this page? It seems to draw away from the general experience of downloading a file. Is this beneficial for bookmarking? Less experienced users? Analytics?

• Stairway to T-SQL DML Level 4: The Mathematics of SQL: Part 1

  A relational database contains tables that relate to each other by key values. When querying data from these related tables you may choose to select data from a single table or many tables. If you select data from many tables, you normally join those tables together using specified join criteria. The concepts of selecting data from tables and joining tables together is all about managing and manipulating sets of data.

• What is a good time/task tracking software to use when consulting?

  - by NeoModulus

  I am looking for time tracking software to use as an individual consulting on multiple projects at once. The projects I work on are billable to different clients. Some clients are billed on an hourly basis while others are billed on a project basis. I also track personal projects that may never produce income. I need to be able to track the time down to the individual task level. I am looking for software that is easy to use, cost effective, easy to invoice out of and has data mining reports.

• How to prepare for an online job interview (maybe through Skype)?

  - by phunehehe

  I'm applying for a company far away and if I get an interview it will probably be done remotely. I have been searching for advices regarding this but all tips seem to be directed at face-to-face meetings (things like "shake hands firmly"). What are the differences? How can I make the best out of those differences? Update: This is a software developer position, so there's also something about technical questions (such as, I can Google anything that they ask ;) This question also applies to any freelancers who are dealing with customers, or recruiters who are interviewing remotely. I hope that makes it relevant to this site. It may also help if you keep answers programers-related.

• Does an incomplete update affect my programs?

  - by Junior

  I saw a pop up which said 'updates are available' so I clicked it. I completely forgot that the installation was incomplete, I logged off. NOw when I came back, it told me to do a partial update. I read the internet for information, partial update wasn't the safest thing for me. I tried to log in to skype, it said another skype may exist. That wasn't true, Skype wasn't opened. I'm not sure if it's because of the incomplete update, but I'm quite off, in trouble. Please reply. Thank you Regards Junior

• How to build completely modular web applications

  - by Webnet

  In the coming months we're going to begin a project where we take a system we've built for a client (v1) and rebuild it from scratch. Our goal with v2 is to make it modular, so that this specific client will have their own set of modules they use, then another client may use a different set of modules altogether. The trick here is that Company A might have a series of checkout and user modules that change how that system works. Company B might stick with the standard checkout procedure but customize how products are browsed. What are some good approaches to application architecture when you're building an application from scratch that you want to have a Core that's shared among all clients while still maintaining the flexability for anything to be modified specifically for a client? I've seen CodeIgniter's hooks and don't think that's a good solution as we could end up with 250 hooks and it's still not flexible enough. What are some other solutions? Ideally we won't need to draw a line in the sand.

• WHy CAps lock is too slow to turn off in Ubuntu?

  - by chtsrl

  *TH*is is a strange problem. *NO*tice how the beginning of my sentences include two capitals? Well, over the years I have developed a terrible habit... and it may be too late to fix. Instead of holding shift like a normal person to capitalize my works, I hit Caps Lock, then hit the letter, then hit Caps Lock again. PRetty weird huh? I Took an official government typing test recently and scored 99 words a minute, so it hasn't been a huge hindrance until now that I use Ubuntu. IN Ubuntu, often when I do my crazy method of typing, the Caps LOck won't turn off fast enough. IT's not my keyboard. I didn't have this problem in WIndows. IT's extremely annoying. Is there a cure for this? Took the question from Ubuntu forums because it's just explaining the same problem I am having here.

• Are VM-based languages becoming viable for Graphics since the move to GPU computing?

  - by skiwi

  Perhaps the title is not the most clear, so let me elaborate it more: I am talking about VM-based languages, by that I mean languages that run on the JVM (java) and for example C#. Also I am talking about 3D graphics, just to be clear. Lately the trend has been that most computing is being done on the GPU and not on the CPU, and since times the issue with programming games on a VM-based language is that garbage collecting may happen randomly. So let's take a look which is responsible for what: Showing the graphics: GPU Uploading graphics to the GPU: CPU? Needs to be done every frame? Calculating physics constraints: GPU Doing the real game logic (Determining when to move objects (independent of physics calculations), processing AI): CPU Is my list actually correct? And if it is, is for example Java becoming more viable? Or is uploading the graphics (vertices) still the most expensive operation? Would like to get more insight into this.

• Pooling (Singleton) Objects Against Connection Pools

  - by kolossus

  Given the following scenario A canned enterprise application that maintains its own connection pool A homegrown client application to the enterprise app. This app is built using Spring framework, with the DAO pattern While I may have a simplistic view of this, I think the following line of thinking is sound: Having a fixed pool of DAO objects, holding on to connection objects from the pool. Clearly, the pool should be capable of scaling up (or down depending on need) and the connection objects must outnumber the DAOs by a healthy margin. Good Instantiating brand new DAOs for every request to access the enterprise app; each DAO will attempt to grab a connection from the pool and release it when it's done. Bad Since these are service objects, there will be no (mutable) state held by the objects (reduced risk of concurrency issues) I also think that with #1, there should be little to no resource contention, while in #2, there'll almost always be a DAO waiting to be serviced. Is my thinking correct and what could go wrong?

• Best way to trigger editing and dynamically show editing features? [on hold]

  - by Tim Marshall

  Page In Question: http://rafflebananza.com/admin/StatisticalData/expenses/expenses.html Hiya Everyone, On my page, I have an 'Actions' drop down to the top-right hand side of the page. This actions drop down I would like to have an action to 'Enable Editing'. Upon clicking to enable editing, I would like a PHP variable modified from 'EnableEditing = false' to 'EnableEditing = true'. Why I would like to use PHP maybe questionable, here is why I would like to use PHP under my understanding to clarify; Sections on my page will show to different administrators depending on their level. Upon enabling editing mode, certain contents will then dynamically. <?php if ($_SESSION['user_level_status'] < 2) { if ($editing = enabled) { show this } else { show this } } ?> Something similar to this, I'm new at PHP so this may look incorrect. The question really is, is PHP the correct language to use to trigger editing and how can I do this please? Best Regards, Tim

• Is it possible to configure Apple's Magic Mouse to be recognised on start up?

  - by Dave

  This question may apply more roundly to all bluetooth mice but in my case I am dealing with an Apple Magic Mouse. I have followed the set up instructions here; https://wiki.ubuntu.com/Multitouch/AppleMagicMouse closely. I have even removed the mouse and started from scratch more than once repeating each step described carefully. Every time the computer is started it does not see the Magic Mouse by default. I need to keep a wired mouse connected to the computer at all times which I use to log in with then connect the Magic Mouse, in a somewhat counter-intuitive exercise! Any help would be greatly appreciated.

• How to create a bookmark under "computer" in the Sidebar of the nautilus file manager in 12.04?

  - by Jiskya

  Somehow, I removed the Downloads bookmark in the Sidebar under "Computer". Is there any way I can make a new one? Possibly with the same icon? I still have my Downloads directory. I just don't have the bookmark under "Computer" anymore, and it has the ordinary folder icon. I know it's not the most significant question, but it's a question nonetheless. Also, I'm not sure, but it may be important to note that I'm using unity 2d.

• Should I create an Enum mapping to my database table

  - by CrazyHorse

  I have a database table containing a list of systems relevant to the tool I am building, mostly in-house applications, or third-party systems we receive data from. This table is added to infrequently, approx every 2 months. One of these systems is Windows itself, which is where we store our users' LANs, and I now need to explicitly reference the ID relating to Windows to query for user name, team etc. I know it would be bad practice to embed the ID itself into the code, so my question is what would be the best way to avoid this? I'm assuming my options are: create a global constant representing this ID create a global enum containing all systems now create a global enum and add systems to it as & when they are required in the code retrieve the ID from the database based on system name I appreciate this may seem a trivial question, but I am going to have many situations like this during the course of this build, and although we are in complete control of the database I would like to conform to best practice as far as possible. Many thanks!

• How can I prevent people from looking at a listing of files in parent directory if I haven't uploaded index.html? [closed]

  - by LedZeppelin

  Possible Duplicate: How to restrict the download of all files in a folder? I haven't uploaded index.html or index.php to my root directory. How can I prevent people from looking at a listing of files in parent directory? http://oi56.tinypic.com/sc739e.jpg Also, is it possible for people to obtain a list of all the files in the root directory once I upload index.html? I'm currently using .htaccess and htusers to prompt someone to enter a username and password when they try to access any file in the root directory. This may sound like a weird request but would it be possible to have them come to the site (without an index.html) and just have them not see the files? All it would say on the page would be the following: Index of/ Apache Server at mysite.com Port 80

• Drawing map tiles for iPhone game

  - by user17778

  I'm working on a turn-based strategy game for the iPhone that has a hexagon-grid based map in it. I'm in the process of drawing up the actual tiles for the different landscapes (i.e. forest, grassland, etc.) and was wondering what program to draw the tile images in. I would assume Adobe Illustrator since a vector-based image may allow for smooth images even when the user is zoomed in really close. Is this right? Thanks!

• Where's Gangnam?

  - by Mike Dietrich

  When somebody did mention "PSY" during a dinner at OOW this year with customers and colleagues from Korea I was completely clueless. I even didn't understand correctly who or what "PSY" is. I did forget about that until last week as a German online magazine did report on over 500 mio youtube hits for "Gangnam Style". Well ... I didn't know that I've almost missed a global phenomenon. And now I've learned that the song is omnipresent in Korea (and not only here) - and Gangnam is a really nice (and expensive) quarter of Seoul not that far away from my hotel. And if you need some rest during your lunch break you may watch these youtube vids - but don't blame me if you don't get the song out of your head anymore ... Gangnam Style by PSY Eton Style - my personal favorite Jakarta Flash Mob - wow! And NO - that's not the type of music I'd usually listen to!!!

• Email forwarding to gmail accounts instead of maintaining a mail server?

  - by user01

  I want to set up 4-5 email addresses on my newly purchased domain(from namecheap.com), for team size of just 2-3 people. But I really don't want to maintain my own mail server(don't have the experience as well as want to avoid the expenses involved, may be I could have kept the mail server alongside my webapp on the web server, but I would avoid). So I came across a workaround option to forward the emails. Thus I could setup email forwarding from namecheap's management console to my free gmail accounts. So all my emails would come to gmail account, convenient & familiar interface as well free. Are there any serious drawbacks of this approach ?
