• Android ACTION_SEND Attached File

  - by Sean

  When you attach a file to an e-mail using the ACTION_SEND intent (with the extra EXTRA_STREAM) does the e-mail app copy that attached file to its own location? My app creates a file and attaches it to an email, but this can happen many times and I would like to be able to delete this file when it is no longer needed (so it doesn't flood the user's storage with junk data). Is the file safe to delete after the e-mail intent has started?

• Find messages[from-to]

  - by Alfred

  I would like to return all messages from certain key to a certain key. The class should be thread-safe and old keys should be able to be deleted say for example after 30 seconds. I was thinking of using a concurrentskiplistset or concurrentskiplist map. Also I was thinking of deleting the items from inside a newSingleThreadScheduledExecutor. I would like to know how you would implement this or maybe use a library?

• Why .data() function of jQuery is better to prevent memory leaks?

  - by burak ozdogan

  Hi, Regarding to jQuery utility function jQuery.data() the online documentation says: "The jQuery.data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. " Why to use: document.body.foo = 52; can result a memory leak -or in what conditions- so that I should use jQuery.data(document.body, 'foo', 52); Should I ALWAYS prefer .data() instead of using expandos in any case? (I would appreciate if you can provide an example to compare the differences) Thanks, burak ozdogan

• Solve math question in PHP

  - by Koning WWWWWWWWWWWWWWWWWWWWWWW

  The user can enter a math problem like 5 + 654, 6 ^ 24, 2!, sqrt(543), log(54), sin 5, sin(50). After some reformatting (e.g. change sin 5 into sin(5)), and doing an eval, PHP gives me the right result. However, this is quite unsafe. Can anyone point me in the right direction parsing and solving a math question like the examples above, which is safe? Thanks.

• Is there a Cocoa equivalent of Apple Event Manager?

  - by Alexey

  Is there a way to handle Apple Events (namely starting the app from a custom protocol link like myapp://do/something/cool) without using the Carbon APIs? If not, is it safe to assume that these APIs are not going to go away in the next release of OS X?

• How to safely store encryption key in a .NET assembly

  - by Alex

  In order to prevent somebody from grabbing my data easily, I cache data from my service as encrypted files (copy protection, basically). However, in order to do this, I must store the encryption key within the .NET assembly so it is able to encrypt and decrypt these files. Being aware of tools like Red Gate's .NET Reflector which can pull my key right out, I get a feeling that this is not a very safe way of doing it... are there any best practices to doing this?

• C# why App.config is copied to my debug and release folder after build?

  - by 5YrsLaterDBA

  I am using Visual Studio 2008 professional, C#. I found the App.config file is copied into the bin\debug and bin\release folder. Is that by default? I thought the XXX.exe.config file will be the only configuration file for a project. Is it safe to release our applicaion without the App.config? if yes, how to ask VS2008 to stop copy that file after build? thanks

  Can anyone recommend a safe solution to recursively replace spaces with underscores in file and directory names starting from a given root directory? For example, $ tree . |-- a dir | `-- file with spaces.txt `-- b dir |-- another file with spaces.txt `-- yet another file with spaces.pdf becomes $ tree . |-- a_dir | `-- file_with_spaces.txt `-- b_dir |-- another_file_with_spaces.txt `-- yet_another_file_with_spaces.pdf

• How to safely use VSS when using a working directory on a thumb drive?

  - by MatthewMartin

  I know putting code into VSS in general is as safe as putting money into a mutual fund run by Bernard Madoff, but I don't have the luxury of ditching it for subversion. That said, I need to be able to write code on two machines, I'm considering checking out code to a flash thumb drive. Anyone know in advance what I should/shouldn't do to avoid loss of work? Do I need to ensure the drive letter stays the same?

• Choosing the MVC view engine

  - by leonard

  I want to allow the end-users of my web application to modify views (via web based back office), stored in the database. The desired view engine is expected to be code-injection safe, meaning that the end-user will be limited to the absolute minimum number of expressions available, no server code inserts are allowed. Is any suitable view engine available to download?

• Postgres: Convert varchar to text

  - by williamjones

  I screwed up and created a column as a varchar(255) where that is no longer sufficient. I've read that varchar has no performance benefits over text on Postgres, and so would like to convert the varchar to a text column in a safe way that preserves the data. What's the best way for me to do this?

• Is there a method in Java that allows me to replace all HTML special characters into their encoded e

  - by Siracuse

  I have a textfile which my Java program is modifying and putting into an HTML file for display. However, this textfile contains lots of HTML unsafe characters such as "<" and the "" which would need to be encoded into & gt; (sans space) and & lt;. Is there some library method I can use to sanatize my text document to replace all these HTML special characters with their safe encoded equivelants?

• Check if webbased CertEnroll will succeed

  - by Tim Mahy

  Hi all, for a project we will be doing webbased certificate enrollment, in Vista / Win7 combination with IE this gives some problems if the user does not import the root certificate first and then changes a lot of default IE settings (Enable ActiveX not marked safe for scripting etc....). I was wondering if any of you ever created a test VB or Javascript to test that all the settings are OK. So it can be used by the user before he starts the enrollment process.... greetings, Tim

• *Right* outer join in LINQ

  - by Rap

  Is it safe to say that there is no such thing as a right outer join in LINQ? I know to effectively create one, you'd just swap the tables in a left outer join. But can you apply the DefaultIfEmpty() method to the table on the left side of the equijoin to make it a right outer join?

• File Upload via PHP and AntiVirus in Linux?

  - by wag2639

  I was wondering, if I was making a file or image hosting/transfer site, whether or not there was a good approach to check for viruses for files that users are uploading? I was thinking of this: Use traditional PHP file upload form to upload the file to the server. Put files in a queue folder Move the queue folder to a "process" folder, and replace queue folder after a predetermined limit (time, cronjob, file count, collective file size) Run a command line virus scan on files in process folder Place safe files in holding area for use Is this a good approach?

• Ways to purge the workspace environment with RAD (based on Eclipse)

  - by Berlin Brown

  I am getting a lot of errors when starting RAD7. The server doesn't respond to class changes. Sometimes the server won't start. Sometimes RAD will not acknowledge modules that I added to the server. It is kind of buggy. I know there is metadata in the workspace, are there safe ways to clean the metadata or RAD in general? Where RAD = Rational Application Developer

• Pros and cons of escaping strategies in symfony

  - by zergu

  I am still not sure in that matter. While turned on we're quite safe but some other problems appear (with passing template variables or counting characters). On the other hand we have magic turned off, everything is clear, but we have to manually escape every variable (that come from untrusted source) in templates. By the way, non-magic solution is used in Ruby-on-Rails. So the question is: when starting a new project in symfony do you disable escaping_strategy and why?

• Do you pay for Subversion support?

  - by Seth Reno

  My team is looking to switch from source safe to something else (finally). I think we have it narrowed down to Team Server 2010 or Subversion. I would prefer Subversion, but my boss has concerns about how we will get support if were using Subversion and something goes wrong. It was suggested that we pay for support. So my question to those out there that use Subversion: Do you pay for support? Have you ever needed it?
