  • Where does the information shown by OS X Terminal 'Display all commands' feature come from?

    - by Sergio Acosta
    I just learned that if you hit and hold ESC while on the Mac Terminal, a prompt appears after a few seconds offering to show every command available on your system, including aliases, built-ins, and executables on your PATH. Soruce: http://www.mactricksandtips.com/2008/05/list-all-possible-terminal-commands.html However, the output is show through a more filter, and I cannot grep it or pipe it to another command. Does anyone know how this magic output is generated? Is it just generated on the fly by Terminal? Is there a bash command that can be called explicitly on the command line and get the same result? It is mostly curiosity, but I would love to be able to get the results as text I can post-process and not just browse on screen.

  • On Windows 7, how can I make the Start Menu search feature include matches from within words, not just the start of the word?

    - by Gabriel
    I have a program installed called WinSCP. When I press the Windows key and type "SCP", I get "No items match your search." Is there a configuration option I can set somewhere, so that this item will be found? I'm not looking for a specific solution for this particular program, but something general, so that if there's a program named XYZ, I can find it via the Start Menu search by entering YZ. EDIT TO ADD: I'm looking for a "set-it and forget-it" type of configuration change, so that within-word searching happens always, automatically. I don't want to have to type a * before every query. Apparently this wasn't clear from what I wrote above.

  • Program (or perhaps built-in feature of Windows 7) to change wallpaper depending on screen resolution?

    - by Lasse V. Karlsen
    I have a laptop with a resolution of 1680x1050. At work I use 2x 1280x1024 monitors, and sometimes I present using a projector that is 1024x768. My wallpaper, that I made for 1680x1050, looks awful on the other resolutions. Is there anything I can do that would make Windows 7 switch to a different wallpaper that has been cropped appropriately? ie. can I give Windows more than one wallpaper, with different resolutions, and have Windows 7 switch automatically to a matching one? If there is a free (or relatively cheap) piece of software I could download and install that would fix it, that would be OK too.

  • How does Windows 7 taskbar "color hot-tracking" feature calculate the colour to use?

    - by theyetiman
    This has intrigued me for quite some time. Does anyone know the algorithm Windows 7 Aero uses to determine the colour to use as the hot-tracking hover highlight on taskbar buttons for currently-running apps? It is definitely based on the icon of the app, but I can't see a specific pattern of where it's getting the colour value from. It doesn't seem to be any of the following: An average colour value from the entire icon, otherwise you would get brown all the time with multi-coloured icons like Chrome. The colour used the most in the image, otherwise you'd get yellow for the SQL Server Management Studio icon (6th from left). Also, the Chrome icon used red, green and yellow in equal measure. A colour located at certain pixel coordinates within the icon, because Chrome is red -indicating the top of the icon - and Notepad++ (2nd from right) is green - indicating the bottom of the icon. I asked this question on ux.stackoverflow.com and it got closed as off-topic, but someone answered with the following: As described by Raymond Chen in this MSDN blog article: Some people ask how it's done. It's really nothing special. The code just looks for the predominant color in the icon. (And, since visual designers are sticklers for this sort of thing, black, white, and shades of gray are not considered "colors" for the purpose of this calculation.) However I wasn't really satisfied with that answer because it doesn't explain how the "predominant" colour is calculated. Surely on the SQL Management Studio icon, the predominant colour, to my eyes at least, is yellow. Yet the highlight is green. I want to know, specifically, what the algorithm is.

  • Where is the Camera Codec feature available in Windows 8?

    - by Rowland Shaw
    If you try to install the Camera Codec pack for Windows 7 on Windows 8, you get an error: This version of the Microsoft Camera Codec Pack is not compatible with Windows 8 or Windows Server 2012. You can get the codec pack through Windows Update on Windows 8. However, I cannot see anywhere on Windows update that would suggest I can download this, even as an optional update? Is it just the case that it is not yet live, as everything filters through the RTM process, or is it hidden away as something else?

  • What XMonad Configuration Best Replicates Default Ion3 Behavior and Feature Set?

    - by mtp
    Not being very familiar with Haskell and lamenting that Ion 3 is now abandonware, I am curious if anyone out there has found a way of replicating the default Ion 3 behavior and aesthetics in XMonad. If I can't have a near-exact replica of Ion 3-style behavior in XMonad, here is what would be critical to me: Virtual desktops that are empty by default and that spawn full-screen applications, which can be split horizontally or vertically evenly, leaving an empty adjacent pane. The panes, which house open windows, are manually resizable, preferably via keyboard. The panes exhibit tabbed behavior, meaning that they can house multiple windows. Windows can be tagged and moved between panes / virtual desktops via keyboard sequence. A given window may be temporarily exploded into full-screen mode via keyboard sequence. Each new virtual desktop starts in the same state—i.e., with one pane. Each virtual desktop may have its panes divided independently of other virtual desktops. From my investigation, it appears that there are several configurations that provide #3. For as much as I want to spend the time to familiarize myself with Haskell, I just simply don't have time. Any suggestions would be greatly appreciated. As far as I can tell, Ion has no conception of master pane or window, so this behavior is not desired.

  • How to get back the themes feature in Windows XP?

    - by Martín M.
    When I try to set a visual style in Windows XP (the standard Luna, for example), I get one of these two: "Access denied" error. It works, but when I restart the computer, I get the Classic look again, with no errors. Also, the "Windows and icons" dropdown is grayed out in the "Appearance". This is a list of things I have tried, with no results: Making sure "Use visual styles on windows" is checked on System Properties Advanced Performance. Restarting the "Themes" service. It starts cleanly, no errors. Applying these two fixes: Kelly's Corner and tweaks.com. Running sfc /scannow and checking the integrity of uxtheme.dll against a clean installation of XP Restoring the whole \Windows\Resources\Themes directory. Creating a new user. The new user does not seem to suffer this problem. Maybe this is the solution, create a new user and migrating all the data, but it would be a pain, and I would prefer reinstalling the whole thing. I am using Windows XP Professional SP3, with no spyware, no virus, and no other visible malfunctions. How can I fix this?

  • How to get a "Maximize" button in every window in GNOME Fallback

    - by RockKeyman
    Just installed Ubuntu 11.10 (AMD64), and immediately switched back to GNOME with GNOME Fallback. I'm searching for a feature which provided a "maximise" button in every window, even ones which should have only the "close" button. In older Ubuntu versions this feature was activated when switching from "None" to "Normal" in "Visual Effects": But now, that window is out, and I can't find that feature. I guess it's somewhere in CompizConfig, but I've searched there with no result. Does anyone know what's the feature I'm searching for?

  • What browser feature is this exploiting and how to stop it ?

    - by ldigas
    http://raffa991.ra.funpic.de/lol/ Warning: It is some kind of an annoying "you are an idiot" sign combined with a lot of popup message boxes. Open with care! In any case, it crashed my firefox 3.5.4. (or to be more precise, made it unusable) ... I don't know about other browsers. Since it's been a while since something that stupid did something like that, I'm wondering ... what weakness is that thing using (Javascript ?), and how to protect oneself from it ?

  • Is there a feature in Nagios that allows Memory between checks?

    - by Kyle Brandt
    There are various instances where there are values I want to monitor with Nagios, and I don't care as much about the value itself, but rather how it compares to the previous value. For instance, I wrote one to check the fail counters in OpenVZ. In this case, I didn't care about the value that much, but rather I cared if the value increased. Another example might be switch ports, I would be most interested to get alerted about the change of state of a port (Although perhaps a trap would be better for this one). For my OpenVZ script, I used a temp file, but I am wondering if there is a better way? Maybe Nagios has some variables that plugins (check scripts) can access that are persistent across checks?

  • How can I add a "Loading...Please wait..." feature?

    - by Rob
    I have a very simple table on my website, that displays different URL's. I have an input field where I can type in a URL and click 'Submit' to add additional URL's. However, I want to add an MD5 grabbing feature to this, using @md5_file(); to grab the MD5 of the URL and check to make sure it's the MD5 it should be, before adding it to the database. However it may take a few seconds for it to grab the MD5 and compare it, so I would like to add a little bit of text, like "Processing...Please wait..." while it does the comparing, and then once it's compared I want that text to go away. I've never done this before, or even though about doing it so I have no idea where to start. I'll go ahead and put javascript as a tag for this, since I'm guessing it would be done with javascript, but I really have no idea. I don't think it's possible with PHP, but again, I have no idea. Any suggestions?

  • How best to implement "favourites" feature? (like favourite products on a data driven website)

    - by ClarkeyBoy
    Hi, I have written a dynamic database driven, object oriented website with an administration frontend etc etc. I would like to add a feature where customers can save items as "favourites", without having to create an account and login, to come back to them later, but I dont know how exactly to go about doing this... I see three options: Log favourites based on IP address and then change these to be logged against an account if the customer then creates an account; Force customers to create an account to be able to use this functionality; Log favourites based on IP address but give users the option to save their favourites under a name they specify. The problem with option 1 is that I dont know much about IP addresses - my Dad thinks they are unique, but I know people have had problems with systems like this. The problem with 1 and 2 is that accounts have not been opened up to customers yet - only administrators can log in at the moment. It should be easy to alter this (no more than a morning or afternoons work) but I would also have to implement usergroups too. The problem with option 3 is that if user A saves a favourites list called "My Favourites", and then user B tries to save a list under this name and it is refused, user B will then be able to access the list saved by user A because they now know it already exists. A solution to this is to password protect lists, but to go to all this effort I may as well implement option 2. Of course I could always use option 4; use an alternative if anyone can suggest a better solution than any of the above options. So has anyone ever done something like this before? If so how did you go about it? What do you recommend (or not recommend)? Many thanks in advance, Regards, Richard

  • How to use R's ellipsis feature when writing your own function?

    - by Ryan Thompson
    The R language has a nifty feature for defining functions that can take a variable number of arguments. For example, the function data.frame takes any number of arguments, and each argument becomes the data for a column in the resulting data table. Example usage: > data.frame(letters=c("a", "b", "c"), numbers=c(1,2,3), notes=c("do", "re", "mi")) letters numbers notes 1 a 1 do 2 b 2 re 3 c 3 mi The function's signature includes an ellipsis, like this: function (..., row.names = NULL, check.rows = FALSE, check.names = TRUE, stringsAsFactors = default.stringsAsFactors()) { [FUNCTION DEFINITION HERE] } I would like to write a function that does something similar, taking multiple values and consolidating them into a single return value (as well as doing some other processing). In order to do this, I need to figure out how to "unpack" the ... from the function's arguments within the function. I don't know how to do this. The relevant line in the function definition of data.frame is object <- as.list(substitute(list(...)))[-1L], which I can't make any sense of. So how can I convert the ellipsis from the function's signature into, for example, a list? To be more specific, how can I write get_list_from_ellipsis in the code below? my_ellipsis_function(...) { input_list <- get.list.from.ellipsis(...) output_list <- lapply(X=input_list, FUN=do_something_interesting) return(output_list) } my_ellipsis_function(a=1:10,b=11:20,c=21:30)

  • Why should I care about RVM's Gemset feature when I use Bundler?

    - by t6d
    I just don't get it. I thought, Bundler was developed to resolve version conflicts between gems. So that I just have to require "bundler/setup" and everything is fine, knowing that Bundler will load the correct versions of all my gems and their dependencies. Now, RVM is great for managing multiple Rubies, I know, but why should I care about the Gemset feature? Do I miss something here? Can it make my development even easier? Maybe, some of you can give me some hints on the perfect RVM + Bundler workflow for both, development and production. I also don't know when RVM starts switching to another Ruby. I know that I can have an .rvmrc file in my project, but do I have to cd to this directory so that the switch happens? Furthermore, I usually use Passenger for development since, thanks to the Passenger.prefpane, integration in Mac OS is great. Can I still do that with RVM or is there a better way to do it? Does Passenger recognize .rvmrc files and switch to the correct Gemset?

  • Question about how AppFabric's cache feature can be used.

    - by Kevin Buchan
    Question about how AppFabric's cache feature can be used. I apologize for asking a question that I should be able to answer from the documentation, but I have read and read and searched and cannot answer this question, which leads me to believe that I have a fundamentally flawed understanding of what AppFabric's caching capabilities are intended for. I work for a geographically disperse company. We have a particular application that was originally written as a client/server application. It’s so massive and business critical that we want to baby step converting it to a better architected solution. One of the ideas we had was to convert the app to read its data using WCF calls to a co-located web server that would cache communication with the database in the United States. The nature of the application is such that everyone will tend to be viewing the same 2000 records or so with only occasional updates and those updates will be made by a limited set of users. I was hoping that AppFabric’s cache mechanism would allow me to set up one global cache and when a user in Asia, for example, requested data that was not in the cache or was stale that the web server would read from the database in the USA, provide the data to the user, then update the cache which would propagate that data to the other web servers so that they would know not to go back to the database themselves. Can AppFabric work this way or should I just have the servers retrieve their own data from the database?

  • Could somebody give me a high-level technical overview of WSGI details behind the scenes vs other we

    - by orokusaki
    Firstly: I understand what WSGI is and how to use it I understand what "other" methods (Apache mod-python, fcgi, et al) are, and how to use them I understand their practical differences What I don't understand is how each of the various "other" methods work compared to something like UWSGI, behind the scenes. Does your server (Nginx, etc) route the request to your WSGI application and UWSGI creates a new Python interpreter for each request routed to it? How much different is is from the other more traditional / monkey patched methods is WSGI (aside from the different, easier Python interface that WSGI offers)? What light bulb moment am I missing?

  • What technical skills needed for algorithmic trading, HFT, etc?

    - by alchemical
    I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.

  • GCC, -O2, and bitfields - is this a bug or a feature?

    - by Rooke
    Today I discovered alarming behavior when experimenting with bit fields. For the sake of discussion and simplicity, here's an example program: #include <stdio.h> struct Node { int a:16 __attribute__ ((packed)); int b:16 __attribute__ ((packed)); unsigned int c:27 __attribute__ ((packed)); unsigned int d:3 __attribute__ ((packed)); unsigned int e:2 __attribute__ ((packed)); }; int main (int argc, char *argv[]) { Node n; n.a = 12345; n.b = -23456; n.c = 0x7ffffff; n.d = 0x7; n.e = 0x3; printf("3-bit field cast to int: %d\n",(int)n.d); n.d++; printf("3-bit field cast to int: %d\n",(int)n.d); } The program is purposely causing the 3-bit bit-field to overflow. Here's the (correct) output when compiled using "g++ -O0": 3-bit field cast to int: 7 3-bit field cast to int: 0 Here's the output when compiled using "g++ -O2" (and -O3): 3-bit field cast to int: 7 3-bit field cast to int: 8 Checking the assembly of the latter example, I found this: movl $7, %esi movl $.LC1, %edi xorl %eax, %eax call printf movl $8, %esi movl $.LC1, %edi xorl %eax, %eax call printf xorl %eax, %eax addq $8, %rsp The optimizations have just inserted "8", assuming 7+1=8 when in fact the number overflows and is zero. Fortunately the code I care about doesn't overflow as far as I know, but this situation scares me - is this a known bug, a feature, or is this expected behavior? When can I expect gcc to be right about this? Edit (re: signed/unsigned) : It's being treated as unsigned because it's declared as unsigned. Declaring it as int you get the output (with O0): 3-bit field cast to int: -1 3-bit field cast to int: 0 An even funnier thing happens with -O2 in this case: 3-bit field cast to int: 7 3-bit field cast to int: 8 I admit that attribute is a fishy thing to use; in this case it's a difference in optimization settings I'm concerned about.

  • Are there any technical problems using an animated GIF for a web site’s favicon instead of an actual

    - by Paul D. Waite
    When putting a favicon on your site, you can apparently use an animated gif, just by changing the gif file’s extension to .ico. http://www.k-director.com/blog/how-to-add-an-animated-faviconico/ Have you encountered any problems doing this? (Aside from users being driven mad by some stupid little blinking favicon.) Have you seen a browser get confused by a gif file with a .ico extension?

    OK, so we all saw the lists of "funny" or "bad" comments.

  • What is the technical skill degree of your co-workers?

    - by bonefisher
    For now it has been around 4 years that I work as developer. Most of my team mates, from their tech-skill, programming ability and code practices view, are somewhere between junior and senior. In all my previous jobs, there was a real geek who was brilliant at coding/analyzing/lead, but the others were just 'average' programmers. How would you rank your co-workers as good developers from rank 1 (best) - 5 (worst) ?

  • "Directly accessing" return values without referencing

    - by undocumented feature
    Look at this ruby example: puts ["Dog","Cat","Gates"].1 This will output Cat as ruby allows me to directly access the "anonymous" array created. If I try this in PHP, however: echo array("Dog","Cat,"Gates")[1] This won't work. What is this called, not only concerning arrays but all functions? Where else is it possible? Feel free to change the question title when you know how this "feature" is called.
