• Code snippets in interview

  - by Maddy

  Hi All, Recently I went to an interview for a C development position. Instead of asking me questions, they just gave me 20 code snippets to find out two logical errors on each one. I just couldn't complete all of the 20 since it took me time to go through each of these code snippets. My question is: Is this the right way to judge a candidate? If yes, how can I improve over my error detection skills so that I don't need to waste a lot of time in the next interview? If possible, please, suggest me some links where I could find lots of samples of such questions (mainly in C). Thanks and regards, Maddy

• Gnome 3 Shell extensions not working on Ubuntu 12.4 [closed]

  - by user63960

  Possible Duplicate: Gnome Shell Extension Empty I just upgraded to Ubuntu 12.4 running on a Win 7 box via VBox and switched the user interface to Gnome 3 but have a problem. In Advanced Settings (gnome tweak), the Shell Extensions window has no listings and the Theme window shows a "caution" triangle next to the Shell theme drop box. I have re-installed the default extensions using the Noobs Lab posted instructions: sudo apt-get install shell-extensions3.4 sudo apt-get install gnome-shell-extensions The commands appear to complete without error. Symptoms are: Gnome 2 visual appearance and no window borders or controls. To close a window, I have to click the window indicator in the sys tray and select the close menu item. Any ideas?

• Create secure working environment on USB stick

  I want to create an usb stick which contains an ubuntu installation that: can be used as a working environment (Covered in: How do I install Ubuntu to a USB key?) - ie the ubuntu installation on the stick must provide an accessible home folder.

How do I realize the complete usb stick encryption? I am also very thankfull for any further articles and ideas on this topic!

• how can I contact Google about a domain misuse?

  - by questy

  I was trying to add a newer domain of mine to my existing Google Apps account with an already set primary domain. Google Apps then returns the message that the domain is already in use by another account. I tried finding a way to contact Google, but they have a wall up preventing anyone with an original Apps account from calling them. There's a help page saying to try retrieving the password, but how is that even possible? I don't know the email address of the owner of the Apps account using my domain, and I don't know his/her name on the account, so I can't complete the form for retrieving any of the information. Google Productforums is always a dead end. Does anyone here know how to force a removal of a domain on Google Apps from someone that doesn't own it?

• How best to take a users signature online? (UK law orientated) [closed]

  - by Ben Griffiths

  Not sure if this is the best place to ask, but I can't seem to find any of the other SE sites that would fit better (unless there's a law one?) I'm building an application that will replace an existing paper based form, and this form would normally be signed by the person filling it in. Looking around, it's hard to find a good definitive resource to explain what I can and cannot accept as far as a signature goes. It looks like some UK government online forms accept just your name typed into a box, but I've also heard you should back up with an email - so that process would be type name into a box along with providing an email address, send out an email, then make them click a link within the email to finally complete the verification. Involving email seems very long winded and leaves the system open to spam filters blocking emails, forgotten emails that just sit in inbox's etc. So, does anyone have any knowledge in this department? Personally, I'd love to just get them to type their name into a box and be done with it!

• Free vs. Paid: Picking a Financial Model

  - by ashes999

  I finally embarked upon my first "paid" game. What this means is that I will incorporate some sort of monetization strategy in my game. This may mean making the app pay-to-download, making it "freemium" with paid content, or something else. Having never done something like this, I'm at a complete loss as to how to figure out what I should do. I know a couple of models (pay to download, freemium, etc.) and I can brainstorm some ideas. But how do I figure out what strategy to use? Perhaps there's some body of research on this? (I recall reading that MMOs popular in Korea use a model where cosmetic changes only are pay-to-buy; everything else is free).

• My first Windows Phone 7 application is live &ndash; from zero to submitted in 5 hours

  - by Eric Nelson

  Tuesday evening I found myself minus family. I decided to use the time to “have a crack at this Silverlight Phone 7 stuff”. From zero (no experience, no tools installed, no membership on the AppHub) to submitted for approval took me from 8pm to 1am – with the last hour messing around with png files in Paint to complete the submission process! Two days later on Thursday it was approved and is now in the marketplace for you to install - or not :-) The application is very simple but it works and looks “finished” – and importantly I learnt a lot about what is involved and the power of our tooling to make this pretty easy to get going. Go on, give it a go by popping over to the App Hub. You do need to pay $99 to join the App Hub to publish but you can start by downloading the free tools and just work with the included emulator.

• Converting large files in python

  - by Cenoc

  I have a few files that are ~64GB in size that I think I would like to convert to hdf5 format. I was wondering what the best approach for doing so would be? Reading line-by-line seems to take more than 4 hours, so I was thinking of using multiprocessing in sequence, but was hoping for some direction on what would be the most efficient way without resorting to hadoop. Any help would be very much appreciated. (and thank you in advance) EDIT: Right now I'm just doing a for line in fd: approach. After that right now I just check to make sure I'm picking out the right sort of data, which is very short; I'm not writing anywhere, and it's taking around 4 hours to complete with that. I can't read blocks of data because the blocks in this weird file format I'm reading are not standard, it switches between three different sizes... and you can only tell which by reading the first few characters of the block.

• Displaying a Sorted, Paged, and Filtered Grid of Data in ASP.NET MVC

  Over the past couple of months I've authored five articles on displaying a grid of data in an ASP.NET MVC application. The first article in the series focused on simply displaying data. This was followed by articles showing how to sort, page, and filter a grid of data. We then examined how to both sort and page a single grid of data. This article looks at how to add the final piece to the puzzle: we'll see how to combine sorting, paging and filtering when displaying data in a single grid. Like with its predecessors, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more! Read More >

• Google Analytics goal funnel does not recognize virtual page views

  - by Webber Smith

  I have a setup wizard with 3 steps. Since I'm using AJAX each step uses a virtual pageview with an appropriate URL for each step (see below). The pageviews are being recorded in the Content section of Google Analytics but the Goal Funnel still shows zero for each step. I've tried advise on other forums such as... Make sure Goal URL is set to Exact match Make sure no steps or the Goal URL are a parent directory of any other steps. For example, don't track /wizard/ as a Goal/step and track /wizard/step2/. Not sure why this would be a problem since it is an exact match, but it shouldn't hurt so I tried it... Require (or don't require - tried both) the first step in the funnel ...but none of these seem to work. Thoughts? Goal Settings Exact match : "/wizard/setup-complete/" Funnel Step 1 : "/wizard/step1/" Step 2 : "/wizard/step2/" Step 3 : "/wizard/step3/"

• Need a really simple client manage script to deliver graphics and revisions, please help?

  - by Mark R

  I am looking for a very simple client management script. The process flow of the script should be: Client orders (paypal etc) while giving specs on what they need given login details and thanked for their order backend for them consists of a 2 way communication. They ask questions we answer. We also upload the graphics here where they either accept them or as for revision. process complete. Now I cannot for the life of me find something as simple as this. It seems all the scripts out there are way too complicated. Does anyone know of one I can use to do this?

• Inventory management system design problem

  - by Steve F

  What are the conventions for item batch identifiers in inventory management systems? For example: A retail supermarket can order 'Item X' from either 'Supplier A' or 'Supplier B'. When it completes an order for the item from either supplier, it needs to store the record of the receipt. Inventory quantity for the item is increased upon receipt of the order. However it is also required to store some record of the supplier. Thus some sort of batch identifier is required. This batch identifier will uniquely identify the item received and the supplier from whom it is received. A new batch is created each time items are received in stock (for example, after an order). Hence, for purposes of accounting / auditing, information available to identify an item after it was sold comprises of ITEM_CODE, ITEM_NAME, BATCH_CODE. The BATCH_CODE is unique and is associated with DATE_RECEIVED, SUPPLIER_CODE, QTY_RECEIVED. Is this a complete system specification for the above scenario or has anything significant been left out?

• Visual Studio 2010 JavaScript Intellisense Behavior

  After I installed Visual Studio 2010 I was having a difficult time editing .js files in Visual Studio. I habitually type the "(" character as soon as the function I want to call is highlighted in the Intellisense window, but in 2010 this behavior was no longer auto-completing the function name. At first I thought this behavior was due to the new "suggestion mode" in Intellisense, but no amount of toggling with CTRL+ALT+SPACE would bring back the auto-complete behavior. It turns out the two...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• Ubuntu 13.10 upgrade error. Dropping to low graphics mode

  - by aero31aero

  I was updating from the terminal and it was complete. It asked me if I would like to reboot now. I accidentally pressed 't' instead of 'y' and then it just asked me to reboot manually. Then I rebooted using sudo shutdown now -r And on reboot, the system flashed the "low graphics mode" error screen and its stuck there. I have 13.10 live-USB with me. Is there any way I can get my system to boot normally? I'm not willing to do a fresh install as I had installed several other packages. Another question: is there any diff if I drop into terminal using Alt+Ctrl+F1 or if I use chroot from a live session?

• LL(8) and left-recursion

  - by Peregring-lk

  I want to understand the relation between LL/LR grammars and the left-recursion problem (for any question I know parcially the answer, but I ask them as I don't know nothing, because I am a little confused now, and prefer complete answers) I'm happy with sintetized or short and direct answers (or just links solving it unambiguously): What type of language isn't LL(8) languages? LL(K) and LL(8) have problems with left-recursion? Or only LL(k) parsers? LALR(1) parser have troubles with left or right recursion? What type of troubles? Only in terms of the LL/LALR comparision. What is better, Bison (LALR(1)) or Boost.Spirit (LL(8))? (Let's suppose other features of them are irrelevant in this question) Why GCC use a (hand-made) LL(8) parser? Only for the "handling-error" problem?

• Is the increase in earning potential for a software developer enough to justify the cost of pursuing a masters degree? [closed]

  - by John Connelly

  Possible Duplicate: Is a Master's worth it? I am considering possibly enrolling in distance education at Kaplan University in order to pursue my masters. On one hand, I would prefer to have more free time so that I can continue to study for certifications and play with the technologies that interest me, work on my little side projects, etc. On the other hand, I am wondering how much difference it can make for my career if I go ahead and get a masters. I have been a .NET programmer since about 2004/2005. I'm currently working in a stable position but possibly considering a move to phoenix when my company's contract runs its course. There is not enough time between now and then for me to be complete with my masters, but I'm just trying to consider whether I should start. The main thing I am trying to determine is really whether or not the increase in earning potential is going to make the cost of pursuing my masters degree a good investment. Any thoughts?

  Suppose someone of your development team is presenting the a sprint to the customer but he is having web connection problems such that a complete storie cannot be presented. For the sake of the cleanness of the presentation, do you help your collegue suggesting posible solutions and try to fix it in the moment? Or is it kind of messy? May be the client (who is "part" of the team) will understand? Why? I'm really looking forward for a good answer! Regards,

• Dell M6800 with Windos 8.1 on part-1, cannot run if Ubuntu and Fedora are 2nd and 3rd OSsen?

  - by user289334

  On a Dell M6800 machine that has Windows 8 pre-installed, I upgraded to 8.1, then I loaded Ubuntu 14.04 then Fedora 20 the only way I could, that is in "Legacy" BIOS Mode. BTW the Ubuntu install was unable to complete but Fedora did, and left all working, 2 bootable OSsen, with Grub2 from Fedora doing the boots, but Windows 8.1 is now "invisible". I have run Boot-Repair but info is not useful. It tells me to switch to UEFI which, on M6800, doesn't work with this (too long-winded to explain why here). I need to have the Grub2 configs "see" the original Windows 8.1 partition, with BIOS switched to "Legacy". BTW various posts have said make switch to UEFI to boot from, say, USB-stick or DVD; this is wrong, you can't - UEFI mode only allows boot from the Windows partition, which it says has a Windows 8.1 on it, which doesn't boot. Basically, if you have actually succeeded in loading Ubuntu 14.04 or Fedora 20 on an M6800, which comes with pre-loaded Windows 8, you will know how I fix this.

• Chrome keeps crashing after updates

  - by Phil

  I'm a chrome user and an enthusiast but few days ago I made Ubuntu get some updates using Update Manager, then I turned off my notebook and when I restarted it, I tried to start Chrome which after a few seconds turned the screen completely black, and some errors appeared for few seconds and then I got logged off, and had to re-login, and when I opened Chrome again the same thing happened! I've uninstalled it with Synaptic and did complete cleanings before re-installing Chrome but nothing succeeded. Now I can't use either Chromium and Chrome, but Firefox works. It's a very strange thing, never happened to me before and I don't know what to do because I had all my bookmarks syncronized in Chrome! Please help if you can :)
