• How do you approach tutorials

  - by aurel

  I get lots of interesting tutorials through feeds and sometimes I implement them step by step, other times I just read through them and note anything that I do not know. When ever I implement them I takes a long time - starting the project, typing the code (as I feel there is no point to copy and paste ), then going back and forth between browser and editing program All in all, I am interested to know how do you learn from the tutorials (I'm no where close to being an expert). Or if you don't use tutorials, is there any other way to learn?

• Research topics for starting and optimizing a high-traffic website

  - by user745434

  I bury a good deal of my ideas for fear that I don't know enough about scaling web applications and high-traffic websites. That said, I'd like to know of any general topics to research in order to ensure that your web app doesn't break / slow down when you start getting to Twitter-level traffic. I'm looking for research topics with, preferably, additional resources. For example: Make sure you optimize SQL queries (see High Performance MySQL Optimization)

• Login keyring box frozen

  - by Maddie

  I'm new to ubuntu and I'm afraid I've done something really stupid. After booting, When prompted to enter a password to unlock my login keyring, I tried to enter in my password, but it won't let me. I can move my cursor but everything else is frozen. I tried to access the terminal by using Ctrl + Alt + F2, I entered my login and password from there and it worked, I just don't know what to do afterwards. Don't know what other information I can provide other than the fact that I am using Ubuntu 10.04

• State machine interpreters

  - by saadtaame

  I wrote my own state machine tool in C and at this point I'm faced with two choices for specifying state machines. Crafting a little language and writing a interpreter. Writing a compiler for that language. I know the advantages/disadvantages of each. I'd like to know what choices game programmers have made for their games. If you've used a state machine in your game in any form, I'd be interested in knowing how you did it.

• A list of the most important areas to examine when moving a project from x86 to x64?

  - by AbrahamVanHelpsing

  I know to check for/use asserts and carefully examine any assembly components, but I didn't know if anyone out there has a fairly comprehensive or industry standard check-list of specific things at which to look? I am looking more at C and C++. note: There are some really helpful answers, I'm just leaving the question open for a couple days in case some folks only check questions that don't have accepted answers.

• Do first-class methods exist?

  - by gdhoward

  Okay, I know first-class functions are cool, closures even better, etc. But is there any language with first-class methods? In my mind, I see a first-class method as an "object" that has both a function pointer and a pointer to a specific instance of the class/object, but the implementation doesn't matter. I just want to know if there is any language that uses them. And as a bonus, how were they implemented?

• Install Script Question

I'm installing sickrage and couchpotato and headphones, and will be doing multiple installs I made a small batch script just to install everything but what I don't know how to do is automatically make them auto start on boot. Since they all require a file to be created I do not know how to make this file auto create and populate what needs to be put into it.

  - by patsee

  I'm trying to create a unity launcher icon (.dekstop file) on which you can drop any (selected/highlighted) text from a web browser, google chrome in my case. I know you can use the "MimeType=" key in a .desktop file, but I can't find the right mime type for my scenario. I've tried several text MimeTypes and "text/*", but none of them would work. Does anyone know which MimeType I have to use in order for my launcher icon to accept text when hovering over it?

• Ranking with PowerPivot – a different approach

  - by Marco Russo (SQLBI)

  Alberto Ferrari wrote an interesting post about a “different approach” in creating a ranking measure with PowerPivot . If you know DAX or you read our book , you will find that a DAX expression can solve the issue. However, such a formula is more complex than necessary. The next version of PowerPivot might have more built-in DAX functions and should solve the ranking need with a simpler formula. In the meantime, it is interesting to know a different approach that relies on Excel skills instead of...(read more)

• Off-Page SEO - Is Backlinking a Sensible Pursuit?

  To qualify what I mentioned in the last article about backlinking and why to me it seems rather a silly way to assess a website's popularity. For us in the know - us internet marketers, of which there are perhaps a million around the globe, who knows, maybe more for us, we know full well that to get our own sites to rank highly in Google and in Yahoo and Bing, we need to get backlinks and we need to get quite a few.

I want to mention here that few arguments to that method are of ref type and few are of value type.

• Need Help with partitions and such Dual Booting 13.10 w/ windows 7

  - by Aymax

  so I've spent the past couple days freaking out about this and looking for answers, and I decided to resort to asking on forums. probably should have before I wasted 2 entire days. so I am trying to DUAL-INSTALL Ubuntu 13.10 with my x64 Windows 7 home premium computer. I have 6 gb of ram, 1TB hard drive, and a 3.3GHZ dual core processer (just in case it matters). I've managed to figure some things out. I've burned the ubuntu files onto a DVD, and I have been able to successfully run it off the disk. I also shrunk my Windows partition by 120Gb and partitioned that for Ubuntu (all using the windows Disk Manager). Problems: When I turn my computer on with the DVD in the tray, the computer cant find windows. it flashes a screen real quick that says something about not being able to find an operating system, and then goes to "grub" and asks what i want to do with Ubuntu. this scares me, because I don't know if that means that I will not be able to boot windows if I install Ubuntu. The Ubuntu 13.10 installer does not detect my Windows operating system. I only have the options to Erase everything on my drive, or "something else." I choose that, which brings me to 3 I don't understand the partition table. I have no idea which drive im selecting to install stuff on, much less which one to select. I tried to tell by the amount of memory partitioned off, but none of the numbers seem to be accurate. Plus, all the names are dev/sda(#). I know Ubuntu knows the name of my partition, because on the sidebars it shows the names of the different drives, including the partition I made; so why don't they use the names? I have no idea what I'm going to be erasing. I've read that I should know which is which by the file system type, but they are all NTFS, including the one I made. my only other option was FAT, none for EXT2 or any of that like people said to do. My main concerns are that of accidentally erasing windows or not being able to access windows. any feasible solution is helpful, weather it helps me with the install or to make Ubuntu see windows. I realize this question has been asked much, but i have found no feasible answers so far. I am relatively new to this, and have never installed an operating system before, so I do not know most of the jargon. please keep it relatively simple, please. I am not a programmer. Thanks.

• Strangling the life out of Software Testing

  - by MarkPearl

  I recently did a course at the local university on Software Engineering. At the beginning of the course I looked over the outline of the subject and there seemed to be some really good content. It covered traditional & agile project methodologies, some general communication and modelling chapters and finished off with testing. I was particularly excited to see the section on testing as this was something I learnt on my own and see great value in. The course has now just ended and I am very disappointed. I now know one of the reasons why so few people i.e. in my region do Test Driven Development, or perform even basic testing methodologies. The topic was to academic! Yes, you might be able to list 4 different types of black box test approaches vs. white box test approaches and describe the characteristics of Smoke Tests, but never during course did we see an example of an actual test or how it might be implemented! In fact, if I did not have personal experience of applying testing in actual projects, I wouldn’t even know what a unit test looked like. Now, what worries me is the following… It took us 6 months to cover the course material, other students more than likely came out of that course with little appreciation of the subject – in fact they now have a very complex view of what a test is – so complex that I think most of them will never attempt it again on their own. Secondly, imagine studying to be a dentist without ever actually seeing a tooth? Yes, you might be able to describe a tooth, and know what it is made out of – but nobody would want a dentist who has never seen a tooth to operate on them. Yet somehow we expect people studying software engineering to do the same? This is not right. Now, before I finish my rant let me say that I know this is not the same everywhere in the world, and that there needs to be a balance on practical implementation and academic understanding – I am just disappointed that this does not seem to be happening at the institution that I am currently studying at ;-( Please, if you happen to be a lecturer or teacher reading this post – a combination of theory and practical's goes a long way. We need to up the quality of software being produced and that starts at learner level!
