  • Coding guidelines + Best Practices?

    - by Chathuranga Chandrasekara
    I couldn't find any question that directly applies to my query so I am posting this as a new question. If there is any existing discussion that may help me, please point it out and close the question. Question: I am going to do a presentation on C# coding guidelines but it is not supposed to limit to coding standards. So I have a rough idea but I think I need to address good programing practices. So the contents will be something like this. Basic coding standards - Casing, Formatting etc. Good practices - Usage of Hashset over other data structures, String vs String Builder, String's immutability and using them effectively etc Really I would like to add more good practices (Especially to improve the performance.) So like to hear some more good practices to be used with C#. Any suggestions??? (No need of large descriptions :) Just the idea is sufficient.)

  • Cisco Secure ACS 4.2 + TACACS+ - installed together or?

    - by Lance
    I'm tasked with installing Cisco Secure ACS (4.2 as its windows based). Do you install TACACS.net or something similar with ACS or does ACS facilitate the TACACS+ authentication? I can get my device to authenticate against a tacacs.net installation without much trouble but can't seem to figure out how one plugs ACS in, per se. I've installed ACS on the same server (is this my problem?) but no matter what I do I can only get my TACACS+ users to authenticate. Any helps/tips would be greatly appreciated!

  • Secure Login add on stopped working after installing BitDefender

    - by ldigas
    I'm using FF 3.5.4. with Secure Login 0.9.3 add on (lovely little thing). After a lot of persuading, my sys admin finally got to me, and I let him install BitDefender on my machine as well ... and naturally, like all anti virus programs do, it had to screw up something, and it was that add on. It says now in the add onns menu, that it isn't compatible with FF 3.5.4. (which is possible, I don' know, but it did work until one hour ago). What to do to make it work again? All ideas welcomed. I really hate writing all that logins/passwords by ahnd.

  • Issues with hard disk secure erase

    - by John Watson
    I want to completely wipe all the data and both OSes (Ubuntu and Windows 7) from my hard drive. I tried DBAN but it gives me an error and does not run. I am looking for an alternative. After reading some articles online, I came to know that, using a Linux live CD, it can be done using either of following commands. a) sudo dd if=/dev/zero of=/dev/sda b) sudo shred -vfz -n 1 /dev/sda My questions are 1) Which option (a or b) is more secure (wipes everything) and faster? 2) Does either of the options damage the hard drive or anything? I want to use hard drive again i.e. installing Windows and Ubuntu again.

  • Secure messaging using Secure MIME is it reliable?

    - by aaronb
    We have an automatic reporting and notification system written in .net that sends emails with plain text. We are having to encrypt the messages that we send our clients. The possible implementation approaches we have: Send messages as S/Mime email with attachments. Plain text email with that just contains a link to a web site that will display the message over https. It seems like S/Mime is a simpler solution, as we won't need to create the web application or secure it. Our concern is our interoperability with our clients email clients and more importantly their email filtering software. Has anyone had success or issues deploying a Secure MIME messaging solution?

  • Arguments, local variables, and global variables coding convention in Python

    - by prosseek
    In python, there is no way to differentiate between arguments, local variables, and global variables. The easy way to do so might be have some coding convention such as Global variables start with _ and capital letter arguments end with with _ _Gvariable = 10 def hello(x_, y_): z = x_ + y_ Is this a Pythonian way to go? I mean, is there well established/agreed coding-standards to differentiate them in python?

  • How can I keep current with Python coding style?

    - by vartec
    I've been using Python since version 2.2. I do pick up new language constructs like for example with statement or dictionary/set comprehensions. However, I've realized that even though I'm being consistent with PEP-8, for existing constructs I'm using old style, rather than new style (for example except Exception, e instead of except Exception as e). Is there a resource which would have either most current style guide, or even better a list of changes in Python's coding style?

  • How to set up secure cookie on weblogic server

    - by adejuanc
    WebLogic Server allows a user to securely access HTTPS resources in a session that was initiated using HTTP, without loss of session data. To enable this feature, add AuthCookieEnabled="true" to the WebServer element in config.xml: <WebServer Name="myserver" AuthCookieEnabled="true"/>Setting AuthCookieEnabled to true, which is the default setting, causes the WebLogic Server instance to send a new secure cookie, _WL_AUTHCOOKIE_JSESSIONID, to the browser when authenticating via an HTTPS connection. Once the secure cookie is set, the session is allowed to access other security-constrained HTTPS resources only if the cookie is sent from the browser.Thus, WebLogic Server uses two cookies: the JSESSIONID cookie and the _WL_AUTHCOOKIE_JSESSIONID cookie. By default, the JSESSIONID cookie is never secure, but the _WL_AUTHCOOKIE_JSESSIONID cookie is always secure. A secure cookie is only sent when an encrypted communication channel is in use. Assuming a standard HTTPS login (HTTPS is an encrypted HTTP connection), your browser gets both cookies.For subsequent HTTP access, you are considered authenticated if you have a valid JSESSIONID cookie, but for HTTPS access, you must have both cookies to be considered authenticated. If you only have the JSESSIONID cookie, you must re-authenticate.To configure on Admin Console : Log into WebLogic Admin Console. Under Domain Structure, press click on <domainname> Select the "Web Applications" tab Select "Lock and Edit" in change center. Click on  "Auth Cookie Enabled" checkbox. Restart to confirm changes. Test an application and view the cookie which got stored as "JSESSIONID" To Configure the Web application's weblogic-application.xml file: Run the following to extract the file from the web application's weblogic-application.xml: $PATH_JDK_HOME\binjar -xvf easy-web-examples.ear META-INF/weblogic-application.xml Add <cookie-secure>true</cookie-secure> between <session-descriptor> </session-descriptor> to the weblogic-application.xml. Run the following to repackage the file to the application: $PATH_JDK_HOME\bin\jar -uvf easy-web-examples.ear META-INF/weblogic-application.xml Deploy the application into WebLogic For further information, please read the documentation on "Using Secure Cookies to Prevent Session Stealing " : http://download.oracle.com/docs/cd/E12840_01/wls/docs103/security/thin_client.html#wp1053780

  • Coding with laptop and external screen - neck, back, comfort ...

    - by Xorty
    Guess I'm not the only one here coding on laptop + external keyboard + external screen. I can't really decide. Figure 1: Putting screen directly in front of (upright) my eyes and move laptop to the side. That feels like more comfortable but I can't really see so good to 15" laptop which is now quite away. Feels unused. Figure 2: Putting laptop in front of me and move external monitor on side. Feels like more efficient space usage, but I am afraid that my neck/back might start hurting since I need to turn my head often. What do you prefer? Some good advice? Sacrificing health is definitely no option here so that's why I'm worried and asking this silly question. Thanks

  • Recommended Reading for Polishing JavaScript coding style?

    - by wml653
    I've been coding in JavaScript for a while now and am fairly familiar with some of the more advanced coding features of the language (closures, self-executing functions, etc). So my question is, what advanced books/blogs/or anything else would be recommended to help tighten up my coding style? For example, recently I was coding something similar to: var x = ['a', 'b', 'c']; var exists = false; for(var i = 0; i < x.length; i++){ exists = x[i] === 'b' ? true : exists; } But found that the following condensed code would work better: var y = {'a':'', 'b':'', 'c':''}; var exists = 'b' in y; Both store the same value in 'exists', but the second is less common, but much cleaner. Any suggestions for where I should go to learn more tricks like this?

  • tips for fixing bad coding/dev habits ?

    - by dfafa
    i want to become a better coder....so i have decided to sign up for computing science program...maybe a formal education can assist me. i started working on smaller projects to learn but currently i have really bad coding/dev habits which is hindering my productivity as the codebase increases.... i have highlighted them and perhaps someone could make suggestions (or redirect to resources) or a more efficient method. most stuff that i made in the past were web apps. i usually develop with putty + nano...i just love the minimalist feel i use winscp and develop directly on my private web server...too lazy to do it on localhost and upload it later. i dont use subversion control...which one do i need ? sometimes ctrl +z doesn't work well. when i run out of ideas for naming variable, i use swear words instead. i swear a lot when i get stuck....how to deal with anger issue ? my codes look ugly with comments everywhere. would rather use procedural coding finds "thinking" in OO difficult and time consuming i "write first think later". refactors code only if i am getting paid for it. dislikes configuring linux distro, Apache, MySQL, scaling, designing graphics and layouts. does not like writing tests likes working alone. does not like sharing codes. has an econ degree dislikes reading other people's code would rather write it on my own it seems my only true desire is to translate my ideas to a working prototype as fast as possible....it seems like i am very uninterested in the other details...could it be that i am not cut out to be a coder after all ? is going back to study comp sci a bad idea ?

  • Should we encourage coding styles in favor of developer's autonomy, or discourage it in favor of consistency?

    - by Saeed Neamati
    A developer writes if/else blocks with one-line code statements like: if (condition) // Do this one-line code else // Do this one-line code Another uses curly braces for all of them: if (condition) { // Do this one-line code } else { // Do this one-line code } A developer first instantiates an object, then uses it: HelperClass helper = new HelperClass(); helper.DoSomething(); Another developer instantiates and uses the object in one line: new HelperClass().DoSomething(); A developer is more easy with arrays, and for loops: string[] ordinals = new string[] {'First', 'Second', 'Third'}; for (i = 0; i < ordinals.Length; i++) { // Do something } Another writes: List<string> ordinals = new List<string>() {'First', 'Second', 'Third'}; foreach (string ordinal in ordinals) { // Do something } I'm sure that you know what I'm talking about. I call it coding style (cause I don't know what it's called). But whatever we call it, is it good or bad? Does encouraging it have an effect of higher productivity of developers? Should we ask developers to try to write code the way we tell them, so to make the whole system become style-consistent?

  • Questions on Juval Lowy's IDesign C# Coding Standard

    - by Jan
    We are trying to use the IDesign C# Coding standard. Unfortunately, I found no comprehensive document to explain all the rules that it gives, and also his book does not always help. Here are the open questions that remain for me (from chapter 2, Coding Practices): No. 26: Avoid providing explicit values for enums unless they are integer powers of 2 No. 34: Always explicitly initialize an array of reference types using a for loop No. 50: Avoid events as interface members No. 52: Expose interfaces on class hierarchies No. 73: Do not define method-specific constraints in interfaces No. 74: Do not define constraints in delegates Here's what I think about those: I thought that providing explicit values would be especially useful when adding new enum members at a later point in time. If these members are added between other already existing members, I would provide explicit values to make sure the integer representation of existing members does not change. No idea why I would want to do this. I'd say this totally depends on the logic of my program. I see that there is alternative option of providing "Sink interfaces" (simply providing already all "OnXxxHappened" methods), but what is the reason to prefer one over the other? Unsure what he means here: Could this mean "When implementing an interface explicitly in a non-sealed class, consider providing the implementation in a protected virtual method that can be overridden"? (see Programming .NET Components 2nd Edition, end of chapter “Interfaces and Class Hierarchies”). I suppose this is about providing a "where" clause when using generics, but why is this bad on an interface? I suppose this is about providing a "where" clause when using generics, but why is this bad on a delegate?

  • Write Secure Cocoa Code

    - by happyCoding25
    Hello, Im making an application in cocoa and wanted to see if some strings in it were easily accessible so I ran OTX on it and sadly all of my code was found. Is there a method I can use to make my code more "secure" or at least encrypt/hide the strings? The reason I want to encrypt the string is it's a password for a server. I don'd need it really secure I just don't want the password to be so easy to find. Thanks for any help

  • HTG Explains: How Windows 8's Secure Boot Feature Works & What It Means for Linux

    - by Chris Hoffman
    Whether you plan on using Windows 8 or not, everyone buying a PC in the future will end up with the Microsoft-driven Secure Boot feature enabled. Secure Boot prevents “unauthorized” operating systems and software from loading during the startup process. Secure Boot is a feature enabled by UEFI – which replaces the traditional PC BIOS – but Microsoft mandates specific implementations for x86 (Intel) and ARM PCs. Any computer with a Windows 8 logo sticker has Secure Boot enabled.
