• Should you do validation checks that go outside the possiblility of normal user activity?

  - by Scarface

  Hey guys I have been thinking about form security a lot lately. I have been told time and time again to check if form input is a number if you are expecting a number or escape it in case (unless you use proper mysqli formatting) to avoid injection. 1.After the safety checks are done, should I do additional logic checks? For example, if the user is sending a friend request to them-self for example even if my user interface will not show the form if the user is looking at their own page.

• Monitoring IIS with SNMP

  - by Shtong

  Hello, I'm trying to monitor IIS using the Windows integrated SNMP service (for versions 2000, 2003 ans 2008 of Windows Server, but i'm doing my experiments on a 2008 R2 box). So far I was able to install the SNMP service, and query mib-2 values without problems. Now, I'm having trouble to monitor IIS informations, as the SNMP service does not seem to know about the .iso.org.dod.internet.private.enterprises.microsoft.software.internetServer OIDs. Walking the entire SNMP tree only gets the mib-2 stuff as well as the names of some services, but that's it. I did't find anything interesting in the service configuration panel. So how do I configure this service to get IIS information, or other WMI data for that matter (I installed the SNMP WMI Provider) ? I can't find any documentation about that !

• Is it possible to deploy a SOAP server with Axis without using WSDD?

  - by Alceu Costa

  In the project I am working I have deployed a SOAP server using Deployment Descriptors (WSDD) files. To do that a webserver (e.g tomcat, jetty) is started and then the following command is executed: java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient deploy.wsdd What I need is to skip the above command to avoid a call to the Axis AdminClient. Is it possible to deploy my webservice as war file? Note: A solution with JWS can't be used due to its limitations.

• Python Code Introspection and Analysis

  - by oneself

  Hi, I am trying to write a Python code analyzer, and I am trying to avoid having to parse bare Python text files. I was hoping that once the Python compiler/interpreter parses the code there's a way to get to the object code or parse tree from within a running Python program. Is there anyway to do this? Thank you

• How to retain background colors when pasting between documents in Excel

  - by Iain Fraser

  I have a script that programatically generates excel spreadsheets - cleaning up ugly reports that are given to us from another organisation. For interests sake; I'm using PHPExcel to generate the "clean" reports. We get these reports every week for an event that happens every couple of months. The reports contain a list of attendees along with a group id that allows us to know that some attendees belong together. To help the event organisers out, I've taken the event ID and generated a unqiue color code (based on the hash of the event ID - truncated to 6 characters). This unique colour code is set as the background color of a cell in each row. This helps organisers quickly visually identify group members. Trouble is, when the organisers copy the rows from the weeks report into the master report (which contains all attendees, not just the ones that signed up this week) - all the colour-codes snap to the master template's color pallette. Thank you very much for your time All the best Iain

• URI encode and HTML ecnode

  - by Anil Namde

  If i have the xml/html data to post we need to encode the data to avoid the XSS validation. So should we use HTMLencode or URI encoding for this. If URI encoding is used will it cause issues as form POST automatically URI encode all the data before sending.

• Premature end of script headers

  - by Tony

  I often get a "premature end of script headers" error in my apache log which results to an internal 500 error. I understand what the error message means - that my application did not give the browser the headers it needs (and maybe nothing at all), but the odd thing is that this does not happen all the time. It actually usually happens the first few times I go to my website after a deploy. Could this be a memory issue? Does anyone know how to trouble shoot this? My apache log isn't really telling me anything. I am running a ruby site using the rails framework on ubuntu hardy. thank you!

• Gtk+ Tables for Layout - Good or Bad?

  - by wag2639

  Hi, I'm just starting to play around with GTK+ and I wanted to stop bad habits before they happen. I see that GTK+ seems to be a little based in HTML/CSS and I was wondering if there are any reasons to avoid using tables for layout.

• Sync Gmail, Google Contacts, Google Calendar with Microsoft Exchange

  - by Steve Dolan

  At my work we only use Microsoft Exchange. As I hate Outlook and much prefer Google's services, I'd like to be able to sync my email, calendar, and contacts to a Gmail account. It looks like Google shut down their Google Sync service for Gmail accounts earlier this year: http://support.google.com/a/bin/answer.py?hl=en&answer=2716936. They are recommending IMAP, CalDAV, and CardDAV. I'm having trouble even setting up IMAP to work with Exchange. Is this the best way to go or is there a better solution?

• Why is an oracle sequence named hibernate_sequence being created with JPA using Hibernate with the O

  - by JavaRocky

  All my entities use this type of @Id @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "MYENTITY_SEQ") @SequenceGenerator(name = "MYENTITY_SEQ", sequenceName = "MYENTITY_SEQ") @Column(name = "MYENTITY", nullable = false) private Long id; Or @Id @Column(name = "MYENTITY") I find that an oracle sequence named hibernate_sequence is always created. Why is this so? And how can i avoid this? I am using JPA1 with Hibernate 3 and the Oracle 10g dialect.

• NHibernate query CreateCriteria

  - by Jacob

  Is it possible to chose what columns I want in return from Session.CreateCriteria() ? egz.: var x = session.CreateCriteria(); x.CreateAlias("EmployeePosition", "employeePosition"); x.Add(Restrictions.Eq("employeePosition.Name", "Developer")); and is there a way to add something like "select LastName" to avoid downloading the whole row.

• creating TAGS for Ruby and emacs

  - by hortitude

  I ran the following from my top level Ruby on Rails directory find . -name "*.rb" | etags - Then within emacs I visited that tag file. This works reasonably well to find some of the methods and most of the files, however it is having trouble finding some of the extra methods/classes that I use in my helpers directory. e.g. I have a file in my helpers dir called my_foo_helper.rb If I search my tags for that file, it finds it. However, if I try to find a tag for one of the methods within that module it doesn't find it at all. If I use Aptana or something like that it seems to be able to locate those methods. Any thoughts? Thanks!

• 10,000 RPM HDD (WD VelociRaptor) vs SSD for OS?

  - by GiH

  I currently have a 10,00RPM 150GB Raptor that I use for Vista. I'm about to upgrade to Windows 7, and while doing that I thought I'd buy another drive and install Ubuntu 9.10 on it. I don't want to partition the current drive I have, but I don't need 150GB for another OS. So, I'm having trouble deciding whether its worth it to buy a 64 GB SSD at the same price point as the 150GB WD VelociRaptor? Or should I just get a 7,200 RPM drive for really cheap (around $50)? Would it be better to use an SSD for the OS than a mechanical drive? I could always get a 32GB SSD too... Oh, and I don't want to virtualize Ubuntu because I'm going to be testing to see the differences in networking and overall performance.

• Edit inherited ACE's using icacls

  - by RedPheonix

  I am trying to write a script that will allow me to replace the user associated with certain permissions with another username. For example say I have a user Administrators and a user Administrator. Using icacls.exe I want to be able to replace all of the permissions given to Administrators and give them to Administrator. I also want to remove all instances of Administrators. So far I have used the following commands: icacls File1.txt /save acls.bin icacls . /substitute Administrator Administrators /restore acls.bin But when I run icacls File1.txt I get: User-PC\Administrator:(F) NT AUTHORITY\SYSTEM:(I)(F) BUILTIN\Administrators:(I)(F) User-PC\User:(I)(F) I have read that icacls has trouble dealing with inherited permissions but I was wondering if there was a method that allowed you to edit all of the permissions including the inherited ones.

• Perl, print with newline

  - by Mike

  In perl most of my print statements take the form print "hello." . "\n"; Is there a nice way to avoid keeping all the pesky "\n"s lying around? I know I could make a new function such as myprint that automatically appends \n, but it would be nice if I could override the existing print.

• Entity Framework: Generating database from classes

  - by Anonymous Coward

  Hi Everyone Is it possible to create the database from the classes with entity framework 4.0? I found many tutorials on how to do it the other way round. But since we have already implemented and tested all classes of the domain we'd like to avoid changing them to much. If I used the wrong keywords in Google I'd appreciate you could post a link. Cheers, CA

• Manage song metadata on CentOS from command line

  - by Puddingfox

  I am making a simple Pandora.com alternative for myself and a few friends where the user can upload his/her songs and listen to them anywhere. My intent is to make a lightweight, simple player in HTML5 so all the user needs is a current Firefox or Chrome to use it. I have set it up so that all uploaded songs get converted to .ogg and added to a database but I also want some metadata (not sure if that is the correct term) for the songs to be stored in the database so the player can tell the user what song he/she is listening too. I know there are several GUI tools for managing the title/artist/album info for songs but I'm having trouble finding any good ones I can use from the command line. If the song has the information already in the file, I think I can use mplayer to retrieve the information but it would be really great if there was one that would look up the song information online. I don't mind interfacing with an API (would be pretty interesting actually). Do you guys have any suggestions?

• RAID P410i and P812 performance issues

  - by Alexey

  I'm having much trouble with I/O performance of HP DL360 server with two RAID controllers - P410i and P812, Windows Server 2008, 36 GiB RAM and 16 x Intel Xeon x5550. The server runs a bunch of tasks producing heavy sequential I/O, and after about 20-30 minutes of intensive work it looks like the tasks are stuck, not using CPU and with enough free memory (so this cannot be a bottleneck). The same tasks were running quite well on the older server (Windows Server 2003, 4 x Intel Xeon, 12 GiB RAM). RAID cache is present, write-cache battery is installed. Cache is configured as 25% readahead/75% writeback. The swap file resides on the logical disk served by P410i and other logical disks are on P812. Can someone tell me what can be the matter of this? Is this a hardware problem or misconfiguration?

• Easiest way to automatically download required modules in Python?

  - by user248237

  I would like to release a python module I wrote which depends on several packages. What's the easiest way to make it so these packages are programmatically downloaded just in case they are not available on the system that's being run? Most of these modules should be available by easy_install or pip or something like that. I simply want to avoid having the user install each module separately. thanks.

  is there any method to avoid the annoying write conflict messages by automating and hiding the process so that it doesn't appear as if the program is defective? there doesn't seem to be any point to these messages anyway as there is only one real choice which is to drop the changes.

• SonarJ like tool for .NET

  - by J. Random Coder

  I'm looking for a tool like SonarJ but for .NET instead of Java. SonarJ helps you to find deviations between he architecture and the code within minutes. It can be integrated into your IDE to help you avoid the introduction of new architetural violations to your code base. You can also use it to maintain metric based software quality rules which will keep complexity under control. I googled and searched SO without satisfying results.
