• Let's improve Visual Studio 2010

  - by Knowing me knowing you

  I wonder if some of you would like the idea to collect in this place features/improvements we would like to see most in visual studio, vote for them and then send them (these with the most votes) to VS Team. Maybe some of them would make their way into another release of VS. Looking forward to see what you're thinking about it.

• Accessing smart card with Java

  - by Tom Brito

  I'm trying to learn about how does Java access smart cards, due to a project analysis. I wonder if there is any kind of virtual smart card which I could use to make some tests with Java? By the way, I've read about Java Card, and looks like it is used to run Java in cards, not to smart card data access, right?

• Are there any free tools for building AIR applications?

  - by rspeed

  There is an ongoing argument on the web right now about the "openness" of the iPhone OS and Adobe Flash platforms. Adobe's argument is that anyone can build a Flash application without having to worry about being allowed to distribute it. This made me wonder… is it possible to build and distribute an AIR application without giving any money to Adobe (without violating any licenses, of course)? Are any of these tools free? Are any open-source?

• Java MessageDigest result does not stay constant

  - by user344146

  I've got this function for encrypting passwords in Java, but somehow when I call MessageDigest, it returns a different result every time even though I call it with the same password. I wonder if I am initializing it wrong somehow. public String encrypt (String password) { MessageDigest md = MessageDigest.getInstance("SHA-1"); md.reset(); md.update(password.getBytes(Charset.forName("utf-8")),0,password.length()); String res = md.digest().toString(); }

• Do USB interrupt transfers guarantee order?

  - by ulidtko

  I've found in the fairly awesome book titled "USB in a NutShell" that interrupt transfers provide reliable delivery (via error detection and automatic retry). But I wonder, does that guarantee that transfers will not be swapped in order someday? As far as the bus is serial, my guess is that yes, reordering should never occur. But I'm not really much into this, so having doubts. Could somebody clarify?

• Android: how to get the walking distance between two geo coordinats?

  - by wei

  I used this query URL http://maps.google.com/maps?q=from+A+to+B&output=kml ,which is given in the answer to this question. But after I tried it, it doesn't work with coordinates. It works with address names tho. I guess I could use google's geocoding to get the addresses first. But I wonder if there is another way to get the walking distance between two coordinates?

• Zend framework forms, upload file problem

  - by bounce

  Hi, I use Zend forms in my web application. I wonder where Zend puts uploded temp file by default ? I can't find it in server tmp dir. For example if I upload image(1.jpg) via file field, it appears on tmp folder, but as 1.jpg(/tmp/1.jpg). But I need temporary file like /tmp/phpeZApBn. Maybe it is in any other location ? Any help would be appreciated.

• jquery document height reported incorrectly by IE (on XP) first time

  - by Zhami

  I'm having a "first time" problem with IE, which reports a different value for $(document).height(); when the page first loads versus subsequent queries. The difference is 17 pixels regardless of the opening size of the window -- on document ready, the height reported is 17 pixels larger than is subsequently reported. I wonder if this is an artifact of some aspect of my page (some margins or paddings somewhere), but so far can't account for 17 pixels.

• Tool to create an amalgamation/combine all source files of a library into one for C/C++?

  - by Anteru

  SQLite and googletest come with a very easy-to-use, single-file version which makes it a breeze to use it in other projects, as you just need to add a single source file. Both of them use home-brew tools to create the combined source file, so I wonder if there is a more generic tool for this?

• Is it bad practice to 'mix class and interfaces in the same package'?

  - by DerMike

  Hello, I just found something that I never heard of before and I do not agree with (by now). In an (upvoted and not further commented) answer I read "why to mix class and interfaces in the same package" So I wonder, if there are reasons to separate Interfaces and implementations in Java. I know that we are not obliged to have all implementations in the package of the interface, but is it (sometimes) wise to have none there? Regards Mike [;-)

  Using Seam 2.1.2 and JSF 1.2 I wonder how to store the users login name in the database.

• is there any faster way to parse than by walk each byte?

  - by uray

  is there any faster way to parse a text than by walk each byte of the text? I wonder if there is any special CPU (x86/x64) instruction for string operation that is used by string library, that somehow used to optimize the parsing routine. for example instruction like finding a token in a string that could be run by hardware instead of looping each byte until a token is found.

• As a programmer, how much time do you spend churning?

  - by Chinnery

  I recently went through a period of frustration, "churning" as I tried to set up my environment to work effectively on a task. By the time I broke through and started to make actual progress, I felt tired and kind of angry. (I'll admit: in this case, it took me several days of banging my head and ultimately starting from scratch to finally get around the problems.) This experience made me wonder: When a roadblock happens to other programmers, how long do they churn before finally becoming productive and beginning what feels like actual work?

• Listing the content of a tar file or a directory only down to some level

  - by Tim

  I wonder how to list the content of a tar file only down to some level? I understand tar tvf mytar.tar will list all files, but sometimes I would like to only see directories down to some level. Similarly, for the command ls, how do I control the level of subdirectories that will be displayed? By default, it will only show the direct subdirectories, but not go further.

• Cycle in Eclipse

  - by Sebi

  If I open two Java projects in Eclipse which depend on each other, I have to add dependencies between these two projects in the Build Path (Properties - Java build path). This works fine for one way, but why doesn't allow Eclipse to set the dependencies vice versa? The following error message occurs: A cycle was detected in the build path of project 'A' and A cycle was detected in the build path of project 'B' I know what's causing this error but i wonder why exactly this isn't allowed. Thanks.
