  • Using Different Mappings for Uppercase and Lowercase of the Same Key

    - by cosmic.osmo
    I'm trying use AutoHotkey to map some key combinations in a way that respects upper and lowercase, but I cannot get it to work. For example: I want: AppsKey + L types "a" AppsKey + Shift + L types "b" A. I've tried these, but both combinations only give "b" ("+" appears to be the symbol for shihft): AppsKey & l::Send a AppsKey & +l::Send b B. I've tried this, but it won't compile and gives a "invalid hotkey error": AppsKey & l::Send a AppsKey & Shift & l::Send b C. I've tried this, but it won't compile and gives a "duplicate hotkey error" (which makes sense as it appears the hotkey definitions are case insensitive): AppsKey & l::Send a AppsKey & L::Send b Is this type of mapping possible in AutoHotkey? What am I missing to make it work?

  • Why does my webpage look different when I connect using different routers?! Does routers cache files?

    - by Ayyash
    Here is the case, I am working on a site from office and home, I recently updated the stylesheets and logged in the live site from office (using my same laptop I use all the time), and everything looks okay, I come home use my home internet connection to connect to the site using the SAME laptop, the styles are not updated! The thing is: this happens on ALL browsers, and after emptying the cache many times, and even after one month of work, and even if I have never opened the site before on that browser (as if my router has a cache of its own) Another thing: only one particular styles.css file seem to be hanging Extra info: I use the same IP for my home wireless router as that defined in the office, the usual 192.168.0.1

  • For an ORM supporting data validation, should constraints be enforced in the database as well?

    - by Ramnique Singh
    I have always applied constraints at the database level in addition to my (ActiveRecord) models. But I've been wondering if this is really required? A little background I recently had to unit test a basic automated timestamp generation method for a model. Normally, the test would create an instance of the model and save it without validation. But there are other required fields that aren't nullable at the in the table definition, meaning I cant save the instance even if I skip the ActiveRecord validation. So I'm thinking if I should remove such constraints from the db itself, and let the ORM handle them? Possible advantages if I skip constraints in db, imo - Can modify a validation rule in the model, without having to migrate the database. Can skip validation in testing. Possible disadvantage? If its possible that ORM validation fails or is bypassed, howsoever, the database does not check for constraints. What do you think? EDIT In this case, I'm using the Yii Framework, which generates the model from the database, hence database rules are generated also (though I could always write them post-generation myself too).

  • Add an entry for Ubuntu on Windows 8 boot loader

    - by John
    I have installed Ubuntu 12.10 by creating free space in Windows 8 and then using that space to create 3 partitions, one for SWAP, one for GRUB (mounting point is /boot) and one for the actual OS. I did this so the Windows 8 boot loader wouldn't be overwritten in case I ever wanted to remove Ubuntu. I can still boot into Ubuntu if I select the boot loader from the BIOS. I want to add Ubuntu to the Windows 8 boot loader and I've been told to use EasyBCD. The issue with that is it doesn't actually direct Windows to the GRUB file, but rather to something like autogrub0.mri. I have found another programme called Visual BCD which will allow me to actually set the bootloader paths and drives. From here, I don't quite know what to do. I believe I have it set to the correct drive but I don't know if I'm directing to the right file. I think it's /boot/grub/x86_64-efi/grub.efi. I don't know if that's the right file, if I need to remove /boot or if the / need to be \ as that's what Windows uses. Sorry for such a lengthy post, please help!

  • How do you keep up with Nagios/Capistrano configs when using EC2?

    - by imaginative
    I use Amazon EC2 for my mobile app. Depending on load of the application at a given time, I might spawn new instances and then take them down when load is lower to save costs. How does one keep up with Nagios configurations for such a dynamic environment? When one deals with managed hardware, configuration files are predictable. In this case Nagios, Capistrano and a bunch of other configuration files would need to be added. Capistrano needs to know where to deploy a new build to for an app server. Nagios needs to know to remove an existing instance or add a new instance for monitoring. Nagios also needs to know if a node was intentionally taken down or if the host is down due to error. How is this done with the wonderful world of VPS/dynamic instances?

  • what to do when ctrl-c can't kill a process?

    - by Dustin Boswell
    Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else. What's the easiest way to force that process to die now without losing my terminal? Summary of answers below: Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools. On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

  • Read the contents of a ComboBox (or any other windows control) [closed]

    - by Homer
    I have a program that reads the contacts from my phone, but I can't export them from it. I'd like to use another program to read the contents of the controls on the original program. In this case, I would like to export the content of a dropdown list (combobox), containing these contacts. Can someone recommend a good program for this or recommend another method? I know I saw something for this last year on lifehacker.com in a collection of diagnostic tools, but I can't find it now.

  • Make Gameobject Stand On Surface Facing Certain Direction

    - by Julian
    I want to make a biped character stand on any surface I click on. Surfaces have up vectors of any of positive or negative X,Y,Z. So imagine a cube with each face being a gameobject whose up vector pointing directly away from the cube. If my character is facing "forward" and I click on a surface which is to the left or right of me ( left or right walls), I want my character to now be standing on that surface but still be facing in the direction he initially was. If I click on a wall which is in the forward path of my character i want him to now be standing on that surface and his forward to now be what was once "up" relative to my character. Here is the code I am working with now. void Update() { if (Input.GetMouseButtonUp (0)) { RaycastHit hit; var ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit)) { Vector3 upVectBefore = transform.up; Vector3 forwardVectBefore = transform.forward; Quaternion rotationVectBefore = transform.rotation; Vector3 hitPosition = hit.transform.position; transform.position = hitPosition; float lookDifference = Vector3.Distance(hit.transform.up, forwardVectBefore); if(Vector3.Distance(hit.transform.up, upVectBefore) < .23) //Same normal { transform.rotation = rotationVectBefore; } else if(lookDifference > 1.412 && lookDifference <= 1.70607) //side wall { transform.up = hit.transform.up; transform.forward = forwardVectBefore; } else //head on wall { transform.up = hit.transform.up; transform.forward = upVectBefore; } } } } The first case "Same normal" works fine, however the other two do not work as I would like them to. Sometimes my character is laying down on the surface or on the wrong side of the surface. Does anyone know nice way of solving this problem?

  • Protected flash video (requires HAL) on Gentoo

    - by Mala
    I am unable to play "protected" flash video, such as Amazon Prime Instant Video. From what I've read and uncovered, this seems to be due to a lack of HAL being installed on my computer. Confirmation that it is required for protected video can be seen towards the beginning of http://helpx.adobe.com/x-productkb/multi/flash-player-11-problems-playing.html However, hal is not in the gentoo portage tree, and in any case has been deprecated and replaced by udev. How can I go about getting Amazon Prime Instant Video to work again? I was considering grabbing the source from http://www.freedesktop.org/wiki/Software/hal but the links there won't load, and trying to install it from old ebuilds or from overlays which claim to still support it (e.g. kde-sunset) result in a compilation error: In file included from addon-generic-backlight.c:38:0: /usr/include/glib-2.0/glib/gmain.h:21:2: error: #error "Only <glib.h> can be included directly." Has anyone else solved this issue?

  • Turn O&M Operations into Optimized Projects with Oracle Primavera

    - by mark.kromer
    Oracle enterprise project portfolio management with Primavera is much more than optimizing project performance and eliminating project failure on new projects, capital programs, etc. A very common use case that we see is small-scale frequent and recurring projects based on on-going operations and maintenance. As opposed to assigning resources to various activities when you are building a new network infrastructure, for example, Oracle has teamed-up the Primavera and eBusiness Suite teams to provide direct integration for work orders from Oracle's Enterprise Asset Management (eAM) system to populate into Primavera P6 project schedules. So now that your network infrastructure build-out project is complete, planners and operations managers can use the world-class what-if and scheduling capabilities in Primavera tools to assign work orders, maximize resource utilization and to reuse templates for typical O&M operations in Primavera and share that back to the operations teams using eAM for maintenance. Also, large-scale maintenance operations related to large assets in the asset lifecycle will include phase-outs, shutdowns and turn-arounds which are classic maintenance projects, as opposed to building something new, that Oracle Primavera with Oracle e-Business Suite provides full coverage to optimize your ALM processes in your business. Read more about these new capabilities from Oracle in the ERP space from the Oracle eAM data sheet.

  • Write to stdin of a running process using pipe

    - by aditya
    I am in a similar situation as in this post But I couln't get the solution provided there to work in my situation as the answer seems related to that question only. In particular, I couldnt understand what was the purpose of cat my.fifo | nc remotehost.tld 10000 In my case, I have a process running and waiting for input. how can I send input to that process using named pipes? I've tried echo 'h' > /proc/PID/fd/0 it just displays 'h' on the process' window.

  • Windows 8 Color Settings (Window Title)

    - by xixixao
    In Windows 7, the window title's color (by default black, to see the title in the title bar fire up Windows Media Player for example) is stored in [HKEY_CURRENT_USER\Control Panel\Desktop\Colors] TitleText value. This is not the case in Windows 8, since this value is only used when using high contrast theme. It looks like noone has come up with a way to change this color yet, so my question is, where to look? What tools can I use to see dependencies, what could be the way to find this value (I rightfully hope it's not a constant in code).

  • Problem with fitting graphics card

    - by Gary Robinson
    I have recently purchased a new radeon hd5670 graphics card. The problem I have is that it is what I might call a double height card. So the end where you fix the card to the case is twice the size of the card it is replacing. But this means that it is blocked by the rear of the network card. The only way I can see it to cut that part of the fixture part out then I won't have a problem. But has anyone any suggestions what I could use? To be clear it is not the actual card it is the fixture part which is 90 degress to the card that is causing the problem. Unless someone knows of another solution - some kind of pci-e extender that I could use as I could easily

  • Broken Package on Update Manager

    - by Widy Graycloud
    I dont know what's wrong with my update manager.. It says that the softwares that I installed was broken. Maybe because I force shutdown my laptop, because Ubuntu wont shutdown,showing up desktop wallpaper but not title bar and launcher, but It won't shut down (+that's another bug). I've just update the broken softwares. the size is 60 to 70 MB.. But It doesn't work. Now I cannot update or install any software from Update Manager or Ubuntu Software Center. Can anybody tellme what's wrong? This is what appears when I use Update Manager I use Ubuntu Software Center, and this message appeared I chose repair and when it update the broken softwares using Ubuntu Software Center. It failed. And show up this message. The problem is I can't update or install any program from Ubuntu Software Center and Device Manager anymore. (I closed allprograms include ubuntu software center,and device manager in this case). Some one helpme? I tried to use apt-get install -f in terminal but it shows message like this: E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied) E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

  • Is it possible to not trigger my normal search highlighting when using search as a movement?

    - by Nathan Long
    When I do a search in vim, I like to have my results highlighted and super-visible, so I give them a bright yellow background and a black foreground in my .vimrc. " When highlighting search terms, make sure text is contrasting colors :highlight Search guibg=yellow guifg=black (This is for GUI versions of vim, like MacVim or Gvim; for command-line, you'd use ctermbg and ctermfg.) But I sometimes use search as a movement, as in c/\foo - "change from the cursor to the next occurrence of foo." In that case, I don't want all the occurrences of foo to be highlighted. Can I turn off highlighting in cases where search is used as a movement?

  • Does exportfs disrupt users already utilizing those filesystems?

    - by CptSupermrkt
    I need to modify a servers /etc/exports file to export to an additional host. After modifying this file, for it to take effect (i.e. for the additional host to have access to the designated filesystem), I believe I have to run "exportfs" on the server exporting the filesystem. Does this disrupt users who are currently using filesystems that are exported from that serving host? I'm hoping to add this new host "silently", without disruption. Any additional advice related to this, common traps, things to be careful of, etc. would be appreciated if you have any. Edit: just in case...uname -a returns 2.6.32-358.18.1.el6.x86_64 #1 SMP Fri Aug 2 17:04:38 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

  • What is better for the overall performance and feel of the game: one setInterval performing all the work, or many of them doing individual tasks?

    - by Bane
    This question is, I suppose, not limited to Javascript, but it is the language I use to create my game, so I'll use it as an example. For now, I have structured my HTML5 game like this: var fps = 60; var game = new Game(); setInterval(game.update, 1000/fps); And game.update looks like this: this.update = function() { this.parseInput(); this.logic(); this.physics(); this.draw(); } This seems a bit inefficient, maybe I don't need to do all of those things at once. An obvious alternative would be to have more intervals performing individual tasks, but is it worth it? var fps = 60; var game = new Game(); setInterval(game.draw, 1000/fps); setInterval(game.physics, 1000/a); //where "a" is some constant, performing the same function as "fps" ... With which approach should I go and why? Is there a better alternative? Also, in case the second approach is the best, how frequently should I perform the tasks?

  • Does it make sense to write build scripts in C++?

    - by Klaim
    I'm using CMake to generate my projects IDE/makefiles, but I still need to call custom "scripts" to manipulate my compiled files or even generate code. In previous projects I've been using Python and it was OK, but now I'm having serious trouble managing a lot of dependencies in two very big projects I'm working on so I want to minimize the dependencies everywhere. Someone suggested to me to use C++ to write my build scripts instead of adding a language dependency just for that. The projects themeselves already use C++ so there are several advantages that I can see: to build the whole project, only a C++ compiler and CMake would be necessary, nothing else (all the other dependencies are C or C++); C++ type safety (when using modern C++) makes everything easier to get "correct"; it's also the language I know the better so I'm more at ease with it even if I'm able to write some good Python code; potential gain in execution speed (but i don't think it will really be perceptible); However, I think there might be some drawbacks and I'm not sure of the real impact as I didn't try yet: might be longer to write the code (that said I'm not sure because I'm efficient enough in C++ to write something that work quickly, so maybe for this system it wouldn't be so long to write) (compilation time shouldn't be a problem for this case); I must assume that all the text files I'll read as input are in UTF-8, I'm not sure it can be easilly checked at runtime in C++ and the language will not check it for you; libraries in C++ are harder to manage than in scripting languages; I lack experience and forsight so maybe I'm missing advantages and drawbacks. So the question is: does it make sense to use C++ for this? do you have experiences to report and do you see advantages and disadvantages that might be important?

  • DVD RW: Are they still relevant for backups?

    - by Harry
    Hello, With the availability of compact USB memory sticks with much, MUCH higher storage capacities is there still any use-case for taking periodic, incremental backups on DVD/RWs? The DVD/RW has an additional annoyance that you cannot drag and drop files to it as easily as you can on a USB memory stick. So, if I have a 4.7GB DVD/RW, I must re-burn the whole image every time I backup new stuff... with possibly rearranged file/folder structure. Secondly, why in this day and age you cannot install a file-system (like ext3 or FAT32) on a DVD/RW... and likewise on CD/RW's as you can on a USB memory stick? Many thanks, /HS

  • Is it possible to have a portable plotter that can print QR codes on burlap?

    - by Brian Ballsun-Stanton
    This is a hardware question. Is there a class of plotters that are portable and accept sharpies? The use case: I have a burlap sack. It will be taking very specific potsherds from an archaeological dig. It needs an indelible QR code (or bar code) printed on the burlap. (Stickers have far far too short a lifetime). It was my thought that a plotter that uses sharpies and that works in the field would be the optimal solution for this problem. Is a portable plotter the right solution? If so, who makes them? If not, what is a better solution?

  • dpkg -S not showing all files in package

    - by dimadima
    I've been using dpkg -S <package_name> to list the contents of a package. Sometimes I pipe to grep bin to quickly scan for executables. I just ran into a case where this didn't work out for me: $ which virtualenv $ sudo apt-get install python-virtualenv Reading package lists... Done ... Setting up python-virtualenv (1.7.1.2-1) ... $ which virtualenv /usr/bin/virtualenv $ dpkg -S /usr/bin/virtualenv python-virtualenv: /usr/bin/virtualenv $ dpkg -S python-virtualenv | grep bin $ /usr/bin/virtualenv seems to be provided by python-virtualenv, but isn't listed in the package contents provided by dpkg -S. All the while, passing /usr/bin/virtualenv to dpkg -S returns that the file comes from python-virtualenv. Can you all explain this?

  • Why is my ethernet interface in promiscuous mode

    Here is a video on this link http://www.youtube.com/watch?v=kSx873lOgIc&feature=player_embedded#at=62 Someone among my bosses wants to create some thing similar to the video on above link and has asked me what software can they use to do the same.The purpose is to create educational content only.Which can have the demonstrations (animations ) and audio also running in backend. I am not clear as what software can be used for this on Linux or Windows. I have users which use Windows and Linux both. I have used video editing on Mac using Final Cut Pro but the video on the above link is not some thing which can be achieved with FCP.(Or may be I am not aware) I am looking solution for 1) Linux users 2) Windows users In case of Linux it is Ubuntu for some users and Fedora for some others. I am a Linux guy so I am specifically posting this question in terms of Ubuntu but I also need suggestions for Windows type of users.I have no clue of such video animations at all.

  • Restoring file properties but not the complete files, from backup

    - by Jon
    While copying data from my old storage on a Linux computer to the new (linux-based) NAS, I accidentially failed with getting the properties (most important: the modify dates) along to the new location. I also continued to use/modify the files at the new location and hence, cannot just copy it all over again. What I would like to do is a diff between files in the old vs. the new storage, and for those being identical, restore the properties from Linux storage to the NAS storage files. Is there a clever way such as a script or a tool to do this? I could either run it on the Linux box or in worst case from a remote Windows computer. Grateful for any suggestions. /Jon
