• Writing temporary data from R

  - by Shane

  I want to write some temporary data to disk in an R package, and I want to be sure that it can run on every OS without assuming the user has admin rights. Is there an existing R function that can provide a path to a temporary directory on all major OS's? Or a way to reference a user's home directory? Otherwise, I was thinking of trying this: Sys.getenv("temp") I presume that I can't expect people to have write access to their R locations, otherwise I could reference a path within the package directory: .find.package("package.name").

• Modify game using external file

  - by Veehmot

  In Flash, for example, I can place an xml file along with the binary, then if I modify some variable the game will change for everyone. How to achieve something like that in Android? I know that for every change I make to the game, the player would need to download a new update. But the main goal I'm looking for, is modifying a game stats without the need for recompile the entire APK. I'm working with Haxe+OpenFL.

• allowing index access only with .htaccess

  - by YsoL8

  Hello I have this in my .htaccess file, in the site root: Options -Indexes <directory ../.*> Deny from all </directory> <Files .htaccess> order allow,deny deny from all </Files> <Files index.php> Order allow,deny allow from all </Files> What I'm trying to achieve is to block folder and file access to anything that isn't called index.php, regardless of which directory is accessed. I have the folder part working perfectly and the deny from all rule is working as well - but my attempt to allow access to index.php is failing. Basically could someone tell me how to get it working?

• Why does running rake gems:unpack result in a Gem::FilePermissionError

  - by Globalkeith

  I'm attempting to upgrade the friendly_id gem in a rails project. I have removed the old gem from the vendor directory, installed the new gem from rubygems.org. When I type: rake gems:unpack I get the following response: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/lib/ruby/gems/1.8 directory. Sure, I realise I can sudo it, but what I don't understand is if I would like to unpack the gem into my project vender directory, why does it need access to /usr/lib/ruby/gems....

• Mixing static and dynamic endpoints in app.yaml file

  - by Greg

  I'm trying to describe endpoints in my App Engine app and am having difficulty for directory structures that mix static and dynamic content. But my yaml rules are conflicting with one another. Before I change my directory structure, does anyone have a recommendation? The goal is to create a directory that contains both documentation (static html files) and implementations. /api - /v1 - getitdone.py - doc.html - index.html What I think I should be doing with my application yaml... - url: /api/v1/getitdone script: api/v1/getitdone.py - url: /api/ static_files: api/index.html upload: api/index.html - url: /api static_dir: api But this causes the dynamic endpoints to fail. I'm assuming the static_dir reference is breaking it. How can I do this without describing every script and static file reference (I have many more than are listed here)?

• Changing resource file in new version of an app

  - by Michael Frost

  Hi, I'm working on an update for an already existing iphone app. The existing version contains a .sql database file which is used in the app. I would like to use a new version of this file in the update of the app. On the first startup of the existing app the .sql file is placed in the caches directory of the users iphone. From what I can understand from Apple's documentation the files in the caches directory might get copied from the old app to the new versions caches directory when the user updates the app. Does this mean that for being sure my new file is used in the updated version I should use a different name of the file? And what happens with the old file? Do I have to manually delete it from inside the app? Which means I have to check if it's there at every startup of the app? Thanks Michael

• User Mode Linux - Installing a module error

  - by Zach

  I am trying to run 'make' on a module in User Mode Linux to install a simple makefile. Here is my make file: obj-m := hello.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules When I run this in User Mode Linux I get the following error: make[1]: Entering directory /lib/modules/2.6.28/build' make[1]: *** No rule to make targetmodules'. Stop. make[1]: Leaving directory `/lib/modules/2.6.28/build' make: * [default] Error 2 The problem is that no files are present under /lib/modules/. There's no directory for 2.6.28 or build. From what I've read, these should be symlinks to /usr/src, but under /usr/src, I don't see any files under that either.

• How to apply Ubuntu patch for rpcbind?

  - by Linda

  I am currently running Ubuntu 12.04.1 Desktop and would like to apply this patch: https://launchpad.net/ubuntu/+source/rpcbind/0.2.0-7ubuntu1.2 My current rpcbind version is here: # aptitude show rpcbind Package: rpcbind State: installed Automatically installed: yes Version: 0.2.0-7ubuntu1.1 As you can see on the patch page, I'd like to patch to this version: Version: 0.2.0-7ubuntu1.2 However, based on the downloadable files on the patch page, I'm not sure where to start. (directory structure of the original rpcbind source) # find rpcbind-0.2.0 -type d rpcbind-0.2.0 rpcbind-0.2.0/src rpcbind-0.2.0/man (directory structure of the patch download) # find debian -type d debian debian/patches debian/source [EDIT] I've figured out how to apply the individual patches in the patches directory: # patch -p1 < ../debian/patches/01-usage-fix.patch patching file src/rpcbind.c (and so on for each patch file) ... but I'm not sure what do with the patch-related files in the root debian folder. Any help here? Thanks in advance, Linda

• LightSwitch Tutorial - Adding Image to a LightSwitch Screen

  - by ChrisD

  Last week, I have discussed how to control Screen Layouts in LightSwitch. Now, I will talk about how to add an image to the LightSwitch screen. In this demo, I will try to upload the image to the screen and will save the image into the database. The first step we need to do is start the VS 2010, create LightSwitch Desktop application with the name “AddingImageIntoScreenInLSBeta2” as shown in the following figure. The second steps, create a table as shown in the screen by selecting the "create a table" option in the start up screen. Then, we need to add a New Data Screen to our demo application. See the following figure which is the default screen layouts for the screen we have created. So we have to change the layout of this screen so that the uploading and using the image in the screen can be easily explained. Before adding the Model Window we have to prepare the layout. So delete the Highlighted fields as shown in the above figure. After preparing the layout to add the image, just add a new Group to the Person Property Rows Layout. To add a new group, [No: 1] – Select the Rows layout, it will shows you the Add button. [No: 2] – Click the Add button to select the new group. [No: 3] – Select the New Group. After adding the new group change the Layout type to Columns Layout. Here, -          Change the rows layout to columns layouts and give the display name as Uploading Image Example. -          Click on the add button to add the Photo field under the column layout. Add a new group under the Column layout group. Follow the [No: #] to create a new group under the columns layout group. After adding a new group of rows layout add the fields to the newly created group. [No: 1] – Select the Rows Layout group and change the display name as Details. [No: 2] – Click on Add button to select the appropriate fields to add to the group. [No: 3] – Add the fields to the group The above snippet shows the complete layout tree for our screen. Now the screen for uploading the image is ready. Just press the Play button. And see the result.

• Boot strapper for VSTO 3.0 SP1

  - by Amjid Qureshi

  Hi, I've got a .net 3.5 vs2008 Excel addin. I've created an installer for it and have it working apart from the fact that I cant get an option in the prerequisites for VSTO 3.0 SP1. I have one for VSTO 3.0 and when I check the C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\VSTOR30 directory it has vstor30.exe vstor30sp1-KB949258-x86.exe product.xml "en" directory. However when I build the installer only the vstor.exe file gets copied over to the bin directory. I need vstor3.0sp1 for the addin to work. If I manually install vstor sp1 then everything works fine.

• Which Document Requires A Single Uri For Web Resources?

  - by Pietro Speroni

  I know that giving short, clear URI that do not change with time is considered good manners, but I need to create a system that is designed not to have them. But to do this I need to go back and find the document in which first it was explained that there should be a single URI per resource. And that it should not change with time. It is probably a document from T.B.L. or from the w3c. Anyone knows which document would that be? Thanks

• Building path independent mod_rewrite statements for generic .htaccess file

  - by Pekka

  Say I have three small web applications stored under a shared web root: www.example.com/app1/ www.example.com/app2/ www.example.com/app3/ www.example.com/app4/ each application has a .htaccess file containing some run-off-the-mill mod_rewrite statements to rewrite urls like RewriteCond %{REQUEST_URI} ^/app1/([^/]+)/([^/]+)\.html$ RewriteRule .* /app1/index.php?selectedProfile=%1&match=%2&%{QUERY_STRING} now, I would like to have a generic .htaccess file in each /app{n} directory. So, no RewriteBase and no /app{n} prefix in the RewriteConds. One idea I had was making the first level a wildcard directory as well: RewriteCond %{REQUEST_URI} ^/([^/]+)/([^/]+)/([^/]+)\.html$ seeing as the .htaccess file gets triggered only when the /app{n} directory is entered, this should work. Is this an acceptable solution? Are there other, better ones?

• How do I execute a shell-command in background?

  - by Adobe

  Here's a simple defun to run a shell script: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " &") nil nil)) If I start a program with no ampersand - it start the script, but blocks emacs until I close the program, if I don't put ampersand it gives error: /home/boris/its/plts/goodies/bk-konsoles.bash /home/boris/scl/geekgeek/: exited abnormally with code 1. Edit: So now I'm using: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " & disown") nil nil) (kill-buffer "*Shell Command Output*")) Edit 2: Nope - doesn't work: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (let ((curDir default-directory)) ;; (shell-command (concat "nohup " (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir) nil nil) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir "& disown") nil nil) (kill-buffer "*Shell Command Output*"))) keeps emacs busy - either with disown, or nohup. Here's a script I'm running if it might be of help: bk-konsoles.bash

• How Microsoft Market DotNet?

  - by Fendy

  I just read an Joel's article about Microsoft's breaking change (non-backwards compatibility) with dot net's introduction. It is interesting and explicitly reflected the condition during that time. But now almost 10 years has passed. The breaking change It is mainly on how bad is Microsoft introducing non-backwards compatibility development tools, such as dot net, instead of improving the already-widely used asp classic or VB6. As much have known, dot net is not natively embedded in windows XP (yes in vista or 7), so in order to use the .net apps, you need to install the .net framework of over 300mb (it's big that day). However, as we see that nowadays many business use .net as their main development tools, with asp.net or mvc as their web-based applications. C# nowadays be one of tops programming languages (the most questions in stackoverflow). The more interesing part is, win32api still alive even there is newer technology out there (and still widely used). Imagine if microsoft does not introduce the breaking change, there will many corporates still uses asp classic or vb-based applications (there still is, but not that much). There are many corporates use additional services such as azure or sharepoint (beside how expensive is it). Please note that I also know there are many flagships applications (maybe adobe's and blizzard's) still use C-based or older language and not porting to newer high-level language. The question How can Microsoft persuade the users to migrate their old applications into dot net? As we have known it is very hard and give no immediate value when rewrite the applications (netscape story), and it is very risky. I am more interested in Microsoft's way and not opinion such as "because dot net is OOP, or dot net is dll-embedable, etc". This question may be constructive, as the technology is vastly changes over times lately. As we can see, Microsoft changes Asp.Net webform to MVC, winform is legacy now, it is starting to change to use windows store rather than basic-installment, touchscreen and later on we will have see-through applications such as google class. And that will be breaking changes. We will need to account portability as an issue nowadays. We will need other than just mere technology choice, but also migration plans. Even maybe as critical as we might need multiplatform language compiler, as approached by Joel's Wasabi. (hey, I read his articles too much!)
