  • What's Your Method of not forgetting the end brackets, parentheses

    - by JMC Creative
    disclaimer: for simplicity sake, brackets will refer to brackets, braces, quotes, and parentheses in the couse of this question. Carry on. When writing code, I usually type the beginning and end element first, and then go back and type the inner stuff. This gets to be a lot of backspacing, especially when doing something with many nested elements like: jQuery(function($){$('#element[input="file"]').hover(function(){$(this).fadeOut();})); Is there a more efficient way of remembering how many brackets you've got open ? Or a second example with quotes: <?php echo '<input value="'.$_POST['name'].'" />"; ?>

  • Personalized URL with pre-populated data

    - by AttackingHobo
    I think I am going to use Google spreadsheets and an embedded form. I see that it is possible to pre-populate the fields with URL parameters. So I think I just need a way to redirect with the correct data from a database when a user goes to their Personalized URL. I have no idea how to do the second part. Or if it is even the best way to do it. How do I set up Personalized URLS? How do I redirect from those URLS to the spreadsheets? Is this even the best method for pre-filled forms?

  • Directory access control with Apache: do I need to use a specific .htaccess?

    - by Mirror51
    I have an Apache webserver, and in the Apache configuration, I have Alias /backups "/backups" <Directory "/backups"> AllowOverride None Options Indexes Order allow,deny Allow from all </Directory> I can access files via http://127.0.0.1/backups. The problem is everyone can access that. I have a web interface, e.g. http://localhost/adminm that is protected with htaccess and password. Now I don't want separate .htaccess and .htpasswd for /backups, and I don't want a second password prompt when a user clicks on /backups in the web interface. Is there any way to use same .htaccess and .htpasswd for the backups directory?

  • Can you tell whether I have a hardware or software problem with a DVD-ROM drive?

    Trying to copy the content of a DVD on a Asrock ION 330 running Maverick, i.e. with: dd if=/dev/sr0 of=dvdcopy ...I get errors in /var/log/messages: Jan 15 17:18:15 asrock kernel: [ 2616.445966] sr 1:0:0:0: [sr0] Unhandled sense code Jan 15 17:18:15 asrock kernel: [ 2616.445975] sr 1:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE Jan 15 17:18:15 asrock kernel: [ 2616.445984] sr 1:0:0:0: [sr0] Sense Key : Medium Error [current] Jan 15 17:18:15 asrock kernel: [ 2616.445994] sr 1:0:0:0: [sr0] Add.

  • RewriteRule for URL Subdirectory Root

    - by JYerdon
    Have not found this in my searches on SE. I need this scenario to work: • User visits someurl.com/news/folder or someurl.com/news/somefolder/, they get redirected to someurl.com/somefolder. • If the user visits JUST someurl.com/news or /news/, they are allowed through to visit /news. Here is my current rule: RewriteRule ^news/(.*) /$1 [NC,R=301,L] How do I make it allow the second bullet point? First seems to work with no issues. Thanks all! POST UPDATE I have got the code RewriteCond %{REQUEST_URI} ^news RewriteRule ^/news news/ [NC,L] RewriteCond %{REQUEST_URI} ^/news/(.)$ RewriteRule ^news/(.) /$1 [NC,R=301,L] BUT - it doesn't allow me to go to the URL something.com/news/ Any thoughts?

  • Phantom activity on MySQL

    - by LoveMeSomeCode
    This is probably just my total lack of MySQL expertise, but is it typical to see lots of phantom activity on a MySQL instance via phpMyAdmin? I have a shared hosting plan through Lithium, and when I log in through the phpMyAdmin console and click on the 'Status' tab, it's showing crazy high numbers for queries. Within an hour of activating my account I had 1 million queries. At first I thought this was them setting things up, but the number is climbing constantly, averaging 170/second. I've got a support ticket in with Lithium, but I thought I'd ask here if this were a MySQL/shared host thing, because I had the same thing happen with a shared hosting plan through Joyent.

  • What's the best way to sell ReSharper to management? [closed]

    - by Jackson Pope
    Possible Duplicate: How do you convince your boss to buy useful tools like Resharper, LinqPad? I've recently started a new job developing code in C# and ASP.Net. At a previous employer I've used ReSharper from JetBrains and I loved it. I've downloaded the free trial in my new job, as have several of my new colleagues on my recommendation. Everyone thinks it's great. But now our trials are coming to an end and it's time to buy or say goodbye. I've been reliably informed that getting money for tools from senior management is like trying to get blood from a stone, so how can I convince them to loosen their grip on the purse strings and buy it for our team (of seven developers)? Does anyone have any experience of convincing management of the benefits of refactoring tools? I feel the benefit every second I use it, but I'm having difficulty thinking of how to explain the concrete benefits to a manager who only think

  • I know of three ways in which SRP helps reduce coupling. Are there even more? [closed]

    - by user1483278
    I'd like to figure all the possible ways SRP helps us reduce coupling. Thus far I can think of three: 1) If class A has more than one responsibility, these responsibilities become coupled and as such changes to one of these responsibilities may require changes to other of A's responsibilities. 2) Related functionality usually needs to be changed for the same reason and by grouping it togerther in a single class, the changes can be made in as few places as possible ( at best changes only need be made to the class which groups together these functionalities) 3) Assuming class A performs two tasks ( thus may change for two reasons ), then number of classes utilising A will be greater than if A performed just a single task ( reason being that some classes will need A to perform first task, other will need A for second task, and still others will utilise it for both tasks ).This also means that when A breaks, the number of classes ( utilising A ) being impaired will be greater than if A performed just a single task. Can SRP also help reduce coupling in any other way, not described above? Thank you

  • Server 13.10 Install Hangs

    - by noloader
    I'm trying to install Server 13.10 on some old hardware for testing (HP/Compaq dc5850, with Athlon X2 2.3 GHz dual core, 4GB RAM). The third screen is "Select Language" and the machine appears to hang. Ath e selection screen, the keyboard and mouse does not work. I integrity checked the CD and it checked out OK. I also performed a second ISO download and it cross checked with my initial download: $ md5 Desktop/ubuntu-13.10-server-amd64.iso Downloads/ubuntu-13.10-server-amd64.iso MD5 (Desktop/ubuntu-13.10-server-amd64.iso) = 4d1a8b720cdd14b76ed9410c63a00d0e MD5 (Downloads/ubuntu-13.10-server-amd64.iso) = 4d1a8b720cdd14b76ed9410c63a00d0e I was able to install Server 12.04 on the same machine. The problem with 12.04 is the OpenStack packages are too old, and I wanted to try something with fresher packages. My problem appears similar to I cannot install Ubuntu Server 12.10. The Installer hangs at the language selection, but my ISOs appear to be good and the disc appears to be good. Any ideas?

  • Retrieve data from an ASP.Net application using ADO.Net 2.0 connected model

    - by nikolaosk
    I have been teaching Entity Framework,LINQ to SQL,LINQ to objects,LINQ to XML for some time now. I am huge fan of LINQ to Entities and I am using Entity Framework as my main data access technology. Entity framework is in the second version right now and I can accomplish most of the things I need. I am sure the guys in the ADO.Net team will implement many more features in the future. I am a strong believer that you cannot really understand the benefits of LINQ to SQL or LINQ to Entities unless you...(read more)

  • returning correct multiTouch id

    - by Max
    I've spent countless hours on reading tutorials and looking at every question related to multiTouch from here and Stackoverflow. But I just cannot figure out how to do this correctly. I use a loop to get my pointerId, I dont see alot of people doing this but its the only way I've managed to get it somewhat working. I have two joysticks on my screen, one for moving and one for controlling my sprites rotation and the angle he shoots, like in Monster Shooter. Both these work fine. My problem is that when I Move my sprite at the same time as Im shooting, my touchingPoint for my movement is set to the touchingPoint of my shooting, since the x and y is higher on the touchingPoint of my shooting (moving-stick on left side of screen, shooting-stick on right side), my sprite speeds up, this creates an unwanted change in speed for my sprite. I will post my entire onTouch method here with some variable-changes to make it more understandable. Since I do not know where Im going wrong. public void update(MotionEvent event) { if (event == null && lastEvent == null) { return; } else if (event == null && lastEvent != null) { event = lastEvent; } else { lastEvent = event; } int pointerCount = event.getPointerCount(); for (int i = 0; i < pointerCount; i++) { int x = (int) event.getX(i); int y = (int) event.getY(i); int id = event.getPointerId(i); int action = event.getActionMasked(); int actionIndex = event.getActionIndex(); String actionString; switch (action) { case MotionEvent.ACTION_DOWN: actionString = "DOWN"; break; case MotionEvent.ACTION_UP: shooting=false; // when shooting is true, it shoots dragging=false; // when dragging is true, it moves actionString = "UP"; break; case MotionEvent.ACTION_POINTER_DOWN: actionString = "PNTR DOWN"; break; case MotionEvent.ACTION_POINTER_UP: shooting=false; dragging=false; actionString = "PNTR UP"; break; case MotionEvent.ACTION_CANCEL: shooting=false; dragging=false; actionString = "CANCEL"; break; case MotionEvent.ACTION_MOVE: try{ if((int) event.getX(id) > 0 && (int) event.getX(id) < touchingBox && (int) event.getY(id) > touchingBox && (int) event.getY(id) < view.getHeight()){ movingPoint.x = (int) event.getX(id); movingPoint.y = (int) event.getY(id); dragging = true; } else if((int) event.getX(id) > touchingBox && (int) event.getX(id) < view.getWidth() && (int) event.getY(id) > touchingBox && (int) event.getY(id) < view.getHeight()){ shootingPoint.x = (int) event.getX(id); shootingPoint.y = (int) event.getY(id); shooting=true; }else{ shooting=false; dragging=false; } }catch(Exception e){ } actionString = "MOVE"; break; default: actionString = ""; } Wouldnt post this much code if I wasnt at an absolute loss of what I'm doing wrong. I simply can not get a good understanding of how multiTouching works. basicly movingPoint changes for both my first and second finger. I bind it to a box, but aslong as I hold one finger within this box, it changes its value based on where my second finger touches. It moves in the right direction and nothing gives an error, the problem is the speed-change, its almost like it adds up the two touchingPoints.

  • Time it would take me to learn c++ given my speed? [closed]

    - by ashwin
    I am a student in second year of engineering and my life is hard, nowadays. To make my future secure and at least get good jobs, I have started learning C++; I have learned J2SE, ASP.NET (little, basic C#), PHP (little), HTML, CSS, AJAX, Javascript, SQL, a little android development (I have built a benchmark app) in 4 months and have received 1 gold medal in CSS and 1 each in HTML, CSS, Java. I am able to make things in C#, Java and all other, so I can apply all this knowledge. I was able to do all this, because I loved learning and I hate to ask this question. How much time would it take me to learn C++, good-enough to get good jobs at Google, Microsoft? I am currently learning data structures, so that's excluded.

  • Set modified date = created date or null on record creation?

    - by User
    I've been following the convention of adding created and modified columns to most of my database tables. I also have been leaving the modified column as null on record creation and only setting a value on actual modification. The other alternative is to set the modified date to be equal to created date on record creation. I've been doing it the former way but I recent ran into one con which is seriously making me think of switching. I needed to set a database cache dependency to find out if any existing data has been changed or new data added. Instead of being able to do the following: SELECT MAX(modified) FROM customer I have to do this: SELECT GREATEST(MAX(created), MAX(modified)) FROM customer The negative being that it's a more complicated query and slower. Another thing is in file systems I believe they usually use the second convention of setting modified date = created date on creation. What are the pros and cons of the different methods? That is, what are the issues to consider?

  • Moving between sites using SAML

    - by System Down
    I'm tasked with developing an SSO system, and was guided towards using the SAML spec. After some research I think understand the interaction between a Service Provider and an ID Provider and how a user's identity is confirmed. But what happens when I redirect the user to another Service Provider? How do I ascertain the user's identity there? Do I send his SAML assertion tokens along with the redirect request? Or does the second Service Provider need to contact the ID Provider all over again?

  • How to bridge the gap between university and job requirements

    - by user1762636
    I study physics and computer science and both studies include minor programming tasks whereas larger tasks are only (potentially) a part of larger projects like for your thesis. When I look at job postings for scientific jobs e.g. in the area of HPC they usually ask for "extensive programming skills in C/C++ and HPC" or the like. This is what I would like to achieve, but frankly I don't know how. I don't mean to mourn, but you can imagine that studying physics/CS means having a busy schedule so I couldn't even work part time as a research assistant to get practice without negative influence on my grades. The second problem is that I lack ideas on what to code in my spare time. I would like to do something useful but even for open source projects you apparently need a whole lot of time and depending on the type of software a lot of experience to be useful. I would be grateful for any advice you can give me.

  • What is the best certification for the self-taught ASP.Net programmer? [closed]

    - by Wahid Bitar
    I learned the C#.Net language from books and many other resources then i did some good projects with ASP.Net "Web Forms & MVC". But i wanna a good certificate to get a better work out of my country as i suppose. I've two choices: Apply for a " college / institute " and start study academic courses to be more professional and maybe in two years I'll "hopefully" graduate with this college certificate. Apply for kind of " Certifications by Companies " like MCTS from Microsoft or something like that and study their straightforward courses then maybe with three or four months I'll get this "Not official Certificate". Is the second type of certifications good for learning and work or the best is the hard way ?. Please give me advises with certifications names please. ======================= Update: This is not related to certain country or region. I'm asking about a good certification and courses for an ASP.Net and C# in general programmer.

  • How to configure kubuntu for lightweight low-memory usage?

    - by augustin
    I just upgraded an old, secondary computer to the latest Kubuntu (10.10). It seems the effort was a bit too much for the hardware and one 512MB memory module died. I tried to take it away, clean the connectors, put it back several times, but to no avail. Until such a time I can find a second hand DDR memory module, I am left with a meagre 256MB RAM, which is below the official requirements (384MB) to run Kubuntu/KDE. Indeed: the computer constantly swaps the memory, making everything painfully slow. Since Kubuntu is already installed and I use it on all my computers (and I want to keep KDE for when I really need it), how can I configure Kubuntu to squeeze out every bit of unnecessary memory usage? This is a secondary computer but still very useful. We use it mostly for web browsing. A "lightweight" tag is missing.

  • DNSCrypt-Proxy specific usage

    - by trekkiejonny
    I have some specific usage questions about DNSCrypt-Proxy. I followed a guide and ended with the command dnscrypt-proxy --daemonize –user=dnscrypt Without any further switches does it default to using OpenDNS's resolver server? I want to use specific servers, I found reference to pointing it to the full path of a CSV file. What is the CSV format for use with DNSCrypt? Would it be "address:port,public key"? Does it go in order of working addresses? For example, first resolver doesn't connect it moves on to the second line of the CSV, then third etc. Lastly, would this question be more appropriate in another StackExchange section?

  • Eleven Eleven Eleven Plus Two

    - by Larry Wake
    You probably already know that Oracle Solaris 11 11/11 was not in fact launched on 11/11/11.  We had our reasons, one of the primary ones being that would have collided with Veterans Day. But I'm going to venture a blog post today--even though it's again of course Veterans Day--to catch up on some news for Oracle Solaris 11's second anniversary (plus two days). Most recently, we had lots to talk about at Oracle OpenWorld -- Markus Flierl gives an excellent recap on his blog. Also, you can now download the various Solaris-related presentations that were given this year.  Find the list and links at: Focus on Oracle Solaris (http://bit.ly/OOW13-Solaris) If you follow the links above, you'll see there's lots to learn about how to get major benefits from Oracle Solaris 11 today, and you'll also find out about some of the new things we're busily at work on as well.  Onward to year three!

  • Cannot boot Windows 7 after installing Ubuntu 13.04

    - by whowantsakookie
    So I boot up my computer after installing Ubuntu 13.04. Grub correctly shows me all available boot options and I am able to boot to Ubuntu. However, when I try to boot into Windows 7, grub hangs at a purple screen. I have an HP laptop. It came with all four primary partitions taken up by the Windows bootloader, the actual Windows partition, one called HP_TOOLS, and another for HP Restore. I was able to back up and delete HP_TOOLS and the recovery partition, and change my disk type from Dynamic to Basic (GParted doesn't recognize Dynamic drives). I then booted into a live session of Ubuntu and made two partitions with GParted: one large partition for storage space that I could use between the two operating systems (sda4), and another extended partition (sda3) which contained Ubuntu (sda6) and it's swap space (sda5). It currently looks like this: I'm not sure if the second paragraph is actually relevant, I just want you to know all the variables in the equation. Thank you in advance for helping this poor noob.
