  • Bash script to replace spaces in file names

    - by armandino
    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?

  • 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?

  • 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?

  • Is single float assignment an atomic operation on the iPhone?

    - by iter
    I assume that on a 32-bit device like the iPhone, assigning a short float is an atomic, thread-safe operation. I want to make sure it is. I have a C function that I want to call from an Objective-C thread, and I don't want to acquire a lock before calling it: void setFloatValue(float value) { globalFloat = value; }

  • 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?

  • 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?

  • Will VS2010 work with VSS2005?

    - by DanH
    Until I can convince others to convert over to Team Foundation Server 2010 (TFS2010), I'm still going to use Visual Source Safe 2005 (VSS2005). I will be upgrade to Visual Studio 2010 (VS2010) soon. What do I need to get VS2010 to work with VSS2005? I understand there is a patch for VSS.

  • 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?

  • Are +=, |=, &= etc atomic?

    - by SF.
    Are the "modify" operators like +=, |=, &= etc atomic? I know ++ is atomic (if you perform x++; in two different threads "simultaneously", you will always end up with x increased by 2, as opposed to x=x+1 with optimization switched off.) What I wonder is whether variable |= constant, and the likes are thread-safe or do I have to protect them with a mutex? (...or is it CPU-dependent? In this case, how is it on ARM?)

  • What is a proper way to store site-level global variables in a SharePoint site?

    - by ccomet
    One thing that has driven me nuts about SharePoint2007 is the apparent inability to have defineable settings that apply specifically to a site or site collection itself, and not the content. I mean, you have some pre-defined settings like the Site Logo, the Site Name, and various other things, but there doesn't appear to be anywhere to add new kinds of settings. The application I am working on needs to be able to create multiple kinds of "project site collections" that all follow a basic template, but have certain additional settings that apply specifically to that site collection and that one alone. In addition to the standard site name we also need to define the Project Number, the Project Name, and the Client Name. And given the requests of some of our clients, we also reach a point where we have to have configurable settings that alter how some of the workflows work, like whether files are marked with Letters or Numbers. Our current solution, which I'm hesitant about, has been to store an XML file on the SharePoint server. This file contains one node for each site collection, identified by the URL of the root site. Inside the node are all of the elements that need to be defined for that site collection. When we need them, we have to access the XML file (which will always require SPSecurity.RunWithElevatedPrivileges to access files right on the server) every time to load it and retrieve the data. There are a lot of automated processes which will have to do this, and I'm hesitant about the stability of this method when we reach hundreds of sites with thousands of files running tens of thousands of workflows, all wanting to access this file. Maybe they're unfounded worries, but I'd rather worry than risk everything breaking in a couple years. I was looking into the SPWeb object and found the AllProperties hashtable. It looks like just the kind of thing which might work, but I don't know how safe it is to be modifying this. I read through both MSDN and the WSS SDK but found nothing that clarified on adding completely new properties into AllProperties. Is it safe to use AllProperties for this kind of thing? Or is there yet another feature that I am missing, which could handle the concept of global variables at the site collection or site scope?

  • how to create a system-wide independent universal counter object primarily for Database keys?

    - by andora
    I would like to create/use a system-wide independent universal 'counter object' that can be called via COM in a thread-safe manner. The counter object will be passed an ID to identify which counter to return, handle the counting, 'persist' the count (occasionally), have reasonable performance (as fast as possible) perhaps capable of 1000 counts per second or better (1mS) and be accessible cross-process/out-of-process. The current count status must be persisted between object restarts/shutdowns. The counter object is liklely to be a 'singleton' type object implemented in some form of free-threaded dictionary, containing maybe 10 counters (perhaps 50 max). The count needs to be monotonic and consistent, (ie: guaranteed unique sequential values). Each counter should have a few methods, like reset, inc, dec, set, clear, remove. As a luxury, I would like to have a variable-increment (ie: 'step by' value). To support thread-safefty, perhaps some sorm of critical-section or mutex call. It just needs to return a long/4byte signed integer. I really want something that can be called from anywhere, including VBScript, so I figure COM is my preferred solution. The primary use of this is for database keys. I am unable to use autoinc or guid type keys and have ruled out database-generated counting systems at this point. I've spent days researching this and I have really struggled to find a solution. The best I can find is a free-threaded dictionary object that can be instantiated using COM+ from Motobit - it seems to offer all the 'basics' and I guess I could create some form of wrapper for this. So, here are my questions: Does such a 'general purpose counter-object already exist? Can you direct me to it? (MS did do an IIS/ASP object called 'MSWC.Counter' but this isn't 'cross-process'/ out-of-process component and isn't thread-safe. (but if it was, it would do!) What is the best way of creating such a Component? (I'd prefer VB6 right-now, [don't ask!] but can do in VB.NET2005 if I had to). I don't have the skills/knowledge/tools to use anything else. I am desparate for a workable solution. I need specific guidance! If anybody can code something up for me I am prepared to pay for it.

  • Android files manipulation

    - by klaus-vlad
    Hi, Through the housekeeping stuff my android application has to do is to read and write some files and sometimes to delete others and create new ones. The files in cause have all "sdcard/" as root. Is it safe if I perform all this task using Java style functions ? To me it is very handy to do it this way but I've read that not always the java functions can be applied when it comes to files in Android.
