• Is it possible to make a script/plugin for Finder to toggle hidden files without relaunching?

  - by Andrei

  There are several ways how to toggle hidden files in Finder - via a shell command, or AppleScript, or Automator action, or even a Dashboard widget. All of them are doing the same thing and unfortunately require to close and reopen Finder windows, which is quite annoying. On the other hand, for the Open File dialog one can easily toggle hidden files by pressing Command+Shift+Period. Is it possible to make a script or plugin for Finder to toggle hidden files w/o relaunching? How would you make it?

• Rotate view of PDF on a WinForm

  - by Dabas

  I have to display a PDF inside a winform (c# on .net 2.0 framework). For now, I am using the ActiveX PDF control provided by Adobe. I have to disable the entire control so that a user can't print or save via right-click or hotkeys. Unfortunately, many of the documents need to be rotated (just viewed, not permanently saved that way). I'd like to allow them to rotate the view by pressing a button control. I've tried enabling the control then programmatically sending the hotkeys (ctrl shift +) using SendKeys and SendInput but the timing issues make this a non-viable solution. I've asked on the proper Adobe boards and they said it was not possible being that all of my clients will only have the reader version installed.

• bitfield mask calculation macro

  - by Aidan Cully

  We have a set of C macros, here, for using the preprocessor to do bitfield operations, and we run into warnings when attempting to use these macros in visual studio. The problem can be demonstrated very easily: #define BITFIELD_WIDTHMASK(Width) \ ((Width) >= 32 ? ~0x0ul : (1ul << (Width)) - 1) unsigned long foo(void) { return BITFIELD_WIDTHMASK(32); } Compiling this with MSVC yields the warning: test.c(12) : warning C4293: '<<' : shift count negative or too big, undefined behavior This isn't a behavior problem - the << operator won't be used in this case, and that should be detected at compile time. But does anyone have any suggestions about how to rewrite the macro to avoid the warning? Or, failing that, how to redesign the macro interface for this? Thanks in advance

• Why doesn't splicing an object from an array in Javascript return the array?

  - by Allen Gould

  I have an array of objects (say, a deck of cards): var deck = []; deck.push(new Card(suit, rank)); The following seems to work: var card = deck.pop(); var card = deck.shift(); (pulling from the "top" or "bottom" of the deck respectively) But if I want a card from the middle (say, if this was a hand of cards) var card = deck.splice(2,1); The object doesn't seem to get properly assigned to the variable (everything is undefined). Everything I look up says that splice should return the object that I'm removing - what am I missing?

• Why is the code adding 7 if the number is not >= 0

  - by Hugo Dozois

  I've got this program in MIPS assembly which comes from a C code that does the simple average of the eigth arguments of the function. average8: addu $4,$4,$5 addu $4,$4,$6 addu $4,$4,$7 lw $2,16($sp) #nop addu $4,$4,$2 lw $2,20($sp) #nop addu $4,$4,$2 lw $2,24($sp) #nop addu $4,$4,$2 lw $2,28($sp) #nop addu $2,$4,$2 bgez $2,$L2 addu $2,$2,7 $L2: sra $2,$2,3 j $31 When the number is positve, we directly divided by 8 (shift by 3 bits), but when the number is negative, we first addu 7 then do the division. My question is why do we add 7 to $2 when $2 is not >= 0 ? EDIT : Here is the C code : int average8(int x1, int x2, int x3, int x4, int x5, int x6, int x7, int x8) { return (x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8) / 8; } note : the possible loss in the division since we are using ints instead of floats or doubles is not important in this case.

• How easy would it be to refactor a small JSP/Servlet/JDBC project to SpringMVC/Hibernate

  - by John

  With reference to this post, I am considering starting a new web-based Java project. Since I don't know Spring/Hibernate I was concerned if it's a bad plan to start learning them while creating a new project, especially since it will slow down the early development. One idea I had was to write a prototype using tech I do know, namely JSP/Servlets/JDBC, since I can get this running much quicker with my current knowledge. I could then throw the whole thing away and start over with Spring, etc, but I'd like to consider how easy it would be to refactor a smallish project from JSP/Servlets/JDB to SpringMVC/Hibernate? My DB could of course be re-used but what about other code... would I expect to save most of it plugged into an MVC framework, or is the paradigm shift big enough this would cause more trouble than it avoids? Please use the other question for more general advice on choosing technologies

• How do I indent multiple lines at once in Notepad++?

  - by cdeszaq

  In many text editors that are aimed at programmers, if the user has a selection that spans more than 1 line and presses the TAB key, those lines are indented by 1 TAB (or a number of spaces, depending on how the editor is configured). However, this does not seem to be the default behavior of Notepad++. Is there a way I can do this in Notepad++, or is there a plugin that I can get to allow me to do this? Edit: Upon additional testing, shift-tab correctly un-indents the lines as expected, but only a tab simply inserts a tab wherever the carat is. This is in version 5.4.5 Unicode

• How to quickly access documentation in Xcode 4.5.1?

  - by International Frog

  How can I quickly access the documentation for a symbol, method, enum, etc. in Xcode 4.5? alt + click on symbol shows a quick-info. Apple removed the dictionary icon which opened the documentation. I tried all other possible shortcuts of the cmd / alt / shift / click mumbo jumbo dance and none of them open the documentation browser. I suppose there is a hidden trick to quickly open it anyways? Edit: Figured out this new quick-info box has a link to the documentation.

• How can I print N array elements with delimiters per line?

  - by Mark B

  I have an array in Perl I want to print with space delimiters between each element, except every 10th element which should be newline delimited. There aren't any spaces in the elements if that matters. I've written a function to do it with for and a counter, but I wondered if there's a better/shorter/canonical Perl way, perhaps a special join syntax or similar. My function to illustrate: sub PrintArrayWithNewlines { my $counter = 0; my $newlineIndex = shift @_; foreach my $item (@_) { ++$counter; print "$item"; if($counter == $newlineIndex) { $counter = 0; print "\n"; } else { print " "; } } }

• C++ shifting bits

  - by Bobby

  I am new to shifting bits, but I am trying to debug the following snippet: if (!(strcmp(arr[i].GetValType(), "f64"))) { dem_content_buff[BytFldPos] = tmp_data; dem_content_buff[BytFldPos + 1] = tmp_data >> 8; dem_content_buff[BytFldPos + 2] = tmp_data >> 16; dem_content_buff[BytFldPos + 3] = tmp_data >> 24; dem_content_buff[BytFldPos + 4] = tmp_data >> 32; dem_content_buff[BytFldPos + 5] = tmp_data >> 40; dem_content_buff[BytFldPos + 6] = tmp_data >> 48; dem_content_buff[BytFldPos + 7] = tmp_data >> 56; } I am getting a warning saying the lines with "32" to "56" have a shift count that is too large. The "f64" in the predicate just means that the data should be 64bit data. How should this be done?

• Aptana function definition popups

  - by DavidYell

  I've noticed that in Aptana 2.0 over 1.5.1 that when typing a php function, you no longer get the popup window showing the function description and it's parameters. Does anyone know how to get this working again? As I relied on it quite heavily to remember which parameters went where. Open in PHP Manual shortcut Shift+F2 also doesn't work either, so all I can do is open my browser and keep php.net open all the time. Are either of these features functional? I know that Open delcaration has never worked annoyingly, but I had the function popup in 1.5.1 perfectly.

• Help regarding no sql databases like hadoop, hbase etc

  - by user560370

  I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

• Overlapping elements stop overlapping in IE7 on class change

  - by Gazzer

  On this page http://zenchan.com/program/ When I rollover the right box 2nd from the top suddenly the overlapping (negative margin disappears). What's happening is that a 'hover' class is being added to shift the background sprite. The two yellow boxes are debugging: if the hover class is put their in advance there is no problem. So fundamentally the CSS is not a problem for IE7 but adding the class is. Any ideas what's causing this. I've tried adding haslayout to various elements but to little effect.

• Is it possible to talk to the iPhone simulator/device.

  - by Plumenator

  I need to automate the build/deploy process for my iphone applications from a script. I can use xcodebuild to build the project, then use Applescript to deploy and debug/run the application. Assuming the application will stop by itself after a while, I need to collect the generated logs for verification. But the problem is I have no way to know when the application ended from outside of the application itself. If the running time is fixed, I can again use Applescript to stop the application (Cmd+Shift+Enter). So there has to be a way to connect to the device/simulator and wait on the application somehow.

• Vim: replacing start and end of a visual char, line or block

  - by gattu marrudu

  I am trying to find a shortcut to place a custom comment sequence on my code, e.g.: /* start of comment blah end of comment /**/ (it is easier to void the comment by just adding a / to the beginning) I would like to do this in Vim by selecting a visual line, block or char and adding '/' characters at the beginning of the block and '/*/' at the end, plus newlines. After selecting some lines (Shift-V) I tried this: '<,'>s/\(.*\)/\/*\r\1\r\/**\// But it adds the comment chars at EACH newline. How can I only apply the substitution at the beginning and end of the selected range? Thanks gm

• Return from parent sub in Perl

  - by JS Bangs

  I want to write a subroutine which causes the caller to return under certain conditions. This is meant to be used as a shortcut for validating input to a function. What I have so far is: sub needs($$) { my ($condition, $message) = @_; if (not $condition) { print "$message\n"; # would like to return from the *parent* here } return $condition; } sub run_find { my $arg = shift @_; needs $arg, "arg required" or return; needs exists $lang{$arg}, "No such language: $arg" or return; # etc. } The advantage of returning from the caller in needs would then be to avoid having to write the repetitive or return inside run_find and similar functions.

• What is the best way to write faster on Vim using a non-english keyboard?

  - by Martín Fixman

  I usually use Vim, and its great for the ability to do faster some actions than other editors. However, since I live in Argentina I have a Latin American keyboard, that makes everything in Vim pretty slower (to write / to search, I must press Shift+7). Since I don't want to be changing Keyboard layouts all the time (and its pretty difficult to get used to pressing symbols as in an English keyboard), I was wondering if there was a vim plugin (of .vimrc file) that may be useful for international users. Just for the sake of it, here's how the Latin American keyboard is laid out: By the way, I would love to go and buy an English keyboard, but unfortunately I use a Laptop.

• Construction an logical expression which will count bits in a byte.

  - by danatel

  When interviewing new candidates, we usually ask them to write a piece of C code to count the number of bits with value 1 in a given byte variable (e.g. the byte 3 has two 1-bits). I know all the common answers, such as right shifting eight times, or indexing constant table of 256 precomputed results. But, is there a smarter way without using the precomputed table? What is the shortest combination of byte operations (AND, OR, XOR, +, -, binary negation, left and right shift) which computes the number of bites?

• When does code bloat start having a noticeable effect on performance?

  - by Kyle

  I am looking to make a hefty shift towards templates in one of my OpenGL projects, mainly for fun and the learning experience. I plan on watching the size of the executable carefully as I do this, to see just how much of the notorious bloat happens. Currently, the size of my Release build is around 580 KB when I favor speed and 440 KB when I favor size. Yes, it's a tiny project, and in fact even if my executable bloats 10 x its size, it's still going to be 5 MB or so, which hardly seems large by today's standards... or is it? This brings me to my question. Is speed proportional to size, or are there leaps and plateaus at certain thresholds, thresholds which I should be aiming to stay below? (And if so, what are the thresholds specifically?)

• why does the gingerbread emulator orientation gets stuck in apps?

  - by tabjsina

  At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

• Intellij UML diagram does not show one to many relationships

  - by Calm Storm

  I am trying to follow http://www.jetbrains.com/idea/features/uml_class_diagram.html I have a few classes so when I do Ctrl + Alt + U I only see all classes and just Extends relationships. Please note that I have set the "Diagrams" options in my settings to show one to many etc. I do not see One to One, One to Many relationships at all ? I have used JPA OneToOne Annotations and they dont turn up at all? Pressing Ctrl Shift F12 does not do anything? Can someone please explain?

• OS X Terminal: Meta key + alt functionality at the same time

  - by abababa22

  Is there a way to use "alt/option" key as a meta key but still be able to use the key to make some characters which need it? For example in my local keyboard layout: @ is alt-2 \ is alt-shift-7 | is alt-7 etc. So if I set alt as meta key, I can't make those characters. On the other hand using "press esc, release esc, press a key" to make meta key sequences makes my hands hurt. Any emacs users with international keyboards who have solved this, please give any tips you might have! :) edit: It appears that I can set alt as meta key and then add these kind of settings in inputrc: "\e2": "@" This works in bash shell but it still won't work with emacs though, so no good.

• Notepad++ Move Caret Outside Bracket

  - by marknadal

  I've searched everywhere and can't find an answer to something incredibly simple and useful for Notepad++. When using autoclose, the cursor gets stuck inside, which is good until I've finished typing the parameters. How do I get the caret to jump outside of the currently nested autoclosed element? Regardless of it being (), {}, [], "", '', ? CTRL+B does does something similar, but it goes to the inside of the left bracket first, and then to the outside of the right bracket, which is where I want to be. This only works for brackets though, not tags and qoutations Hitting CTRL+B twice is cumbersome and manually hitting "right arrow" requires too much hand motion while coding. And finally, is there anyway I can map this to "SHIFT+Space"?

• Does a c/c++ compiler optimize constant divisions by power-of-two value into shifts?

  - by porgarmingduod

  Question says it all. Does anyone know if the following... size_t div(size_t value) { const size_t x = 64; return value / x; } ...is optimized into? size_t div(size_t value) { return value >> 6; } Do compilers do this? (My interest lies in GCC). Are there situations where it does and others where it doesn't? I would really like to know, because every time I write a division that could be optimized like this I spend some mental energy wondering about whether precious nothings of a second is wasted doing a division where a shift would suffice.
