• Change present working directory of a calling shell from a ruby script

  - by Erik Kastman

  I'm writing a simple ruby sandbox command-line utility to copy and unzip directories from a remote filesystem to a local scratch directory in order to unzip them and let users edit the files. I'm using Dir.mktmpdir as the default scratch directory, which gives a really ugly path (for example: /var/folders/zz/zzzivhrRnAmviuee+++1vE+++yo/-Tmp-/d20100311-70034-abz5zj) I'd like the last action of the copy-and-unzip script to cd the calling shell into the new scratch directory so people can access it easily, but I can't figure out how to change the PWD of the calling shell. One possibility is to have the utility print out the new path to stdout and then run the script as part of a subshell (i.e. cd $(sandbox my_dir) ), but I want to print out progress on the copy-and-unzipping since it can take up to 10 minutes, so this won't work. Should I just have it go to a pre-determined, easy-to-find scratch directory? Does anyone have a better suggestion? Thanks in advance for your help. -Erik

• ReadOnlyCollection or IEnumerable for exposing member collections?

  - by Erik Öjebo

  Is there any reason to expose an internal collection as a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection? class Bar { private ICollection<Foo> foos; // Which one is to be preferred? public IEnumerable<Foo> Foos { ... } public ReadOnlyCollection<Foo> Foos { ... } } // Calling code: foreach (var f in bar.Foos) DoSomething(f); As I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does not allow the user to modify the collection. So if the IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I missing something? Thanks /Erik

• Unit Testing & Fake Repository implementation with cascading CRUD operations

  - by Erik Ashepa

  Hi, i'm having trouble writing integration tests which use a fake repository, For example : Suppose I have a classroom entity, which aggregates students... var classroom = new Classroom(); classroom.Students.Add(new Student("Adam")); _fakeRepository.Save(classroom); _fakeRepostiory.GetAll<Student>().Where((student) => student.Name == "Adam")); // This query will return null... When using my real implementation for repository (NHibernate based), the above code works (because the save operation would cascade to the student added at the previous line), Do you know of any fake repository implementation which support this behaviour? Ideas on how to implement one myself? Or do you have any other suggestions which could help me avoid this issue? Thanks in advance, Erik.

• PHP - CSRF - How to make it works in all tabs?

  - by Erik Persson

  Hi there, I have readed about how to prevent CSRF-attacks in the last days. I am going to update the token in every pageload, save the token in the session and make a check when submitting a form. But what if the user has, lets say 3 tabs open with my website, and I just store the last token in the session? This will overwrite the token with another token, and some post-action is going to fail. Do I need to store all tokens in the session, or is there a better solution to get this working? Best regards, Erik Persson

• MVVM/Presentation Model With WinForms

  - by Erik Ashepa

  Hi, I'm currently working on a brownfield application, it's written with winforms, as a preparation to use WPF in a later version, out team plans to at least use the MVVM/Presentation model, and bind it against winforms... I've explored the subject, including the posts in this site (which i love very much), when boiled down, the main advantage of wpf are : binding controls to properties in xaml. binding commands to command objects in the viewmodel. the first feature is easy to implement (in code), or with a generic control binder, which binds all the controls in the form. the second feature is a little harder to implement, but if you inherit from all your controls and add a command property (which is triggered by an internal event such as click), which is binded to a command instance in the ViewModel. The challenges I'm currently aware of are : implementing a commandmanager, (which will trigger the CanInvoke method of the commands as necessery. winforms only supports one level of databinding : datasource, datamember, wpf is much more flexible. am i missing any other major features that winforms lacks in comparison with wpf, when attempting to implement this design pattern? i sure many of you will recommend some sort of MVP pattern, but MVVM/Presentation model is the way to go for me, because I'll want future WPF support. Thanks in advance, Erik.

• function (blurClass) NOT WORKING IN IE

  - by Erik

  I can't get this plugin to function properly in IE.... Check out my homepage and look at the huge search field toward the top... www.naturalskin.com Whenever I refresh the screen the "blur" looses its function and I'm stuck with text..... Here is the script that I place in an external js page: http://www.naturalskin.com/src/js/javascript/batches.js jQuery.fn.hint = function (blurClass) { if (!blurClass) { blurClass = 'blur'; } return this.each(function () { // get jQuery version of 'this' var $input = jQuery(this), // capture the rest of the variable to allow for reuse title = $input.attr('title'), $form = jQuery(this.form), $win = jQuery(window); function remove() { if ($input.val() === title && $input.hasClass(blurClass)) { $input.val('').removeClass(blurClass); } } // only apply logic if the element has the attribute if (title) { // on blur, set value to title attr if text is blank $input.blur(function () { if (this.value === '') { $input.val(title).addClass(blurClass); } }).focus(remove).blur(); // now change all inputs to title // clear the pre-defined text when form is submitted $form.submit(remove); $win.unload(remove); // handles Firefox's autocomplete } }); }; Erik

• PHP: Next Available Value in an Array, starting with a non-indexed value

  - by Erik Smith

  I've been stumped on this PHP issue for about a day now. Basically, we have an array of hours formatted in 24-hour format, and an arbitrary value ($hour) (also a 24-hour). The problem is, we need to take $hour, and get the next available value in the array, starting with the value that immediately proceeds $hour. The array might look something like: $goodHours = array('8,9,10,11,12,19,20,21). Then the hour value might be: $hour = 14; So, we need some way to know that 19 is the next best time. Additionally, we might also need to get the second, third, or fourth (etc) available value. The issue seems to be that because 14 isn't a value in the array, there is not index to reference that would let us increment to the next value. To make things simpler, I've taken $goodHours and repeated the values several times just so I don't have to deal with going back to the start (maybe not the best way to do it, but a quick fix). I have a feeling this is something simple I'm missing, but I would be so appreciative if anyone could shed some light. Erik

• Why can't i change the permissions of files I have access to?

  - by Erik

  I'm logged into a server as user "ubuntu" and I've got files that look like this: -rw-rw-r-- 1 www-data www-data 33150 2012-06-04 22:17 file-a.png -rw-rw-r-- 1 www-data www-data 36371 2012-06-04 22:15 file-b.png -rw-rw-r-- 1 www-data www-data 41439 2012-06-04 22:16 file-c.png the ubuntu user is a member of the group www-data: > groups unbuntu ubuntu : ubuntu www-data so shouldn't I be able to change other permissions since I have access to the file? I'm not an expert on the user/group stuff ... so this is just perplexing me. I'm trying to run: > chmod o-r * I realize I can do it with sudo, easily, but I'm trying to understand why I can't modify the files without sudo. Thanks for any help!

• Can I use CodeSynthesis XSD (C++/Tree mapping) together with a GPLv3-licensed library?

  - by Erik Sjölund

  Is it possible to write an open source project that uses generated code from CodeSynthesis XSD (C++/Tree) and then link it to a third-party library that is licensed under the GPL version 3? Some background information: CodeSynthesis XSD is licensed under the GPL version 2 but with an extra FLOSS exception (http://www.codesynthesis.com/projects/xsd/FLOSSE). C++ source code generated from CodeSynthesis XSD (C++/Tree) needs to be linked against Xerces (http://xerces.apache.org/xerces-c/) that is licensed under the Apache License 2.0. Update I posted a similar question on the xsd-users mailing list two years ago but I didn't fully understand the answers. In that email thread, I wrote: I think it is the GPL version 3 software that doesn't allow itself be linked to software that can't be "relicensed" to GPL version 3 ( for instance GPL version 2 software ). That would also include XSD as the FLOSS exception doesn't give permission to "relicense" XSD to GPL version 3.

• VIM does not detect syntax of .ssh/config

  - by Erik

  On a plain Ubuntu installation (12.04 in my case) when I have no ~/.vimrc VIM does not detect syntax of .ssh/config. Syntax highlighting works, but it does not set the correct filetype. vi ~/.ssh/config :set syn? >syntax=conf When I do: set syn=sshconfig Then the syntax highlighting is as it should be. Why isn't the filetype automatically identified? And how can it be set automatically?

• Automatic login vs. manual login and screensaver lock

  - by Erik Johansson

  Is there a way to prevent a command from running when I login manually, but having it run when the computer starts up and GDM automatically logs me in. This is the setup: in the Gnome "on start programs" settings I have a command that locks the screen gnome-screensaver-command -l I have automatic login turned on. That means that the screen will be locked when I turn on the computer, but it will also be locked when I manually login from GDM, is there a way to prevent this?

• New Management Console in Java SE Advanced 8u20

  - by Erik Costlow-Oracle

  Java SE 8 update 20 is a new feature release designed to provide desktop administrators with better control of their managed systems. The release notes for 8u20 are available from the public JDK release notes page. This release is not a Critical Patch Update (CPU). I would like to call attention to two noteworthy features of Oracle Java SE Advanced, the commercially supported version of Java SE for enterprises that require both support and specialized tools. The new Advanced Management Console provides a way to monitor and understand client systems at scale. It allows organizations to track usage and more easily create and manage client configuration like Deployment Rule Sets (DRS). DRS can control execution of tracked applications as well as specify compatibility of which application should use which Java SE installation. The new MSI Installer integrates into various desktop management tools, making it easier to customize and roll out different Java SE versions. Advanced Management Console The Advanced Management Console is part of Java SE Advanced designed for desktop administrators, whose users need to run many different Java applications. It provides usage tracking for those Applet & Web Start applications to help identify them for guided DRS creation. DRS can then be verified against the tracked data, to ensure that end-users can run their application against the appropriate Java version with no prompts. Usage tracking also has a different definition for Java SE than it does for most software applications. Unlike most applications where usage can be determined by a simple run-count, Java is a platform used for launching other applications. This means that usage tracking must answer both "how often is this Java SE version used" and "what applications are launched by it." Usage Tracking One piece of Java SE Advanced is a centralized usage tracker. Simply placing a properties file on the client informs systems to report information to this usage tracker, so that the desktop administrator can better understand usage. Information is sent via UDP to prevent any delay on the client. The usage tracking server resides at a central location on the intranet to collect information from those clients. The information is stored in a normalized database for performance, meaning that a single usage tracker can handle a large number of clients. Guided Deployment Rule Sets Deployment Rule Sets were introduced in Java 7 update 40 (September 2013) in order to help administrators control security prompts and guide compatibility. A previous post, Deployment Rule Sets by Example, explains how to configure a rule set so that most applications run against the most secure version but a specific applet may run against the Java version that was current several years ago. There are a different set of questions that can be asked by a desktop administrator in a large or distributed firm: Where are the Java RIAs that our users need? Which RIA needs which Java version? Which users need which Java versions? How do I verify these answers once I have them? The guided deployment rule set creation uses usage tracker data to identify applications both by certificate hash and location. After creating the rules, a comparison tool exists to verify them against the tracked data: If you intend to run an RIA, is it green? If something specific should be blocked, is it red? This makes user-testing easier. MSI Installer The Windows Installer format (MSI) provides a number of benefits for desktop administrators that customize or manage software at scale. Unlike the basic installer that most users obtain from Java.com or OTN, this installer is built around customization and integration with various desktop management products like SCCM. Desktop administrators using the MSI installer can use every feature provided by the format, such as silent installs/upgrades, low-privileged installations, or self-repair capabilities Customers looking for Java SE Advanced can download the MSI installer through their My Oracle Support (MOS) account. Java SE Advanced The new features in Java SE Advanced make it easier for desktop administrators to identify and control client installations at scale. Administrators at organizations that want either the tools or associated commercial support should consider Java SE Advanced.

• How to credit other authors in an open source project

  - by erik

  I have a pet project that I am planning to release as open source at some point in the not-too-distant future. A couple of the files use or are mostly code that was taken from a project released under the New BSD License. While I have changed it to fit my needs and added some small stuff, the algorithm and the functionality is basically exactly the same. I want to make sure that the author of the code gets credit and that the license is not broken, but I also want to make the reader aware that this is not the code as it was orignally released. How should I approach this? Should I isolate the code as much as possible and just retain the original license? Maybe put all the files that contain foreign code in their own folder and add a readme explaining what has been added/removed? There must have been tons of projects using other open source code. What is the standard approach to this?

• Running a webbrowser on the screen saver or login screen.

  - by Erik Johansson

  I would really like people to beable to use my locked computer to surf, so I would like some way to run a browser on login screen. So can I make GDM run firefox in some way? It would be cooler if I could have a browser as a screensaver, but that seems a bit harder. Please ignore all the security problems with this, if you let someone use your computer you have lost that race anyways. Though of course it would be nice to have a browser running as another user.

• Unmounted disk still spins up regularly

  - by Erik Johansson

  I just added a disk, with partitions but none of them are mounted. The disk will still spin up every now and then. it goes like this: ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.37.08 CET ### disk spins up hdparm -Y /dev/sdb;date /dev/sdb: issuing sleep command 9 feb 2011 23.46.12 CET Also it always spins up when I shut down the computer. Any tips are welcome, e.g. how can I figure out which process is accessing the disk, are there any daemons doing this? I know it isn't a cron job.

• Difference left/right super button

  - by Erik Keemink

  When I press my left super key the gnome shell appears and when I press the right super key it does not. Moreover pressing right super + T does open a terminal at once, but when using left super I have to press the t twice, when I press the t only once it is similar to just pressing the t without holding super left. This last point also occurs with other shortcuts that I defined (like super+L, super+E), but not with super+up/down/left/right. What I want is to press either super key to get the gnome shell and to use either super key in combination with T to open a terminal immediately (and similar with other shortcuts). I use Ubuntu 12.04 LTS and the gnome 3 shell.

• Are there any formalized/mathematical theories of software testing?

  - by Erik Allik

  Googling "software testing theory" only seems to give theories in the soft sense of the word; I have not been able to find anything that would classify as a theory in the mathematical, information theoretical or some other scientific field's sense. What I'm looking for is something that formalizes what testing is, the notions used, what a test case is, the feasibility of testing something, the practicality of testing something, the extent to which something should be tested, formal definition/explanation of code coverage, etc. UPDATE: Also, I'm not sure, intuitively, about the connection between formal verification and what I asked, but there's clearly some sort of connection.

• How to define type-specific scripts when using a 'type object' programming pattern?

  - by Erik

  I am in the process of creating a game engine written in C++, using the C/C++ SQLite interface to achieve a 'type object' pattern. The process is largely similar to what is outlined here (Thank you Bob Nystrom for the great resource!). I have a generally defined Entity class that when a new object is created, data is taken from a SQLite database and then is pushed back into a pointer vector, which is then iterated through, calling update() for each object. All the ints, floats, strings are loaded in fine, but the script() member of Entity is proving an issue. It's not much fun having a bunch of stationary objects laying around my gameworld. The only solutions I've come up with so far are: Create a monolithic EntityScript class with member functions encompassing all game AI and then calling the corresponding script when iterating through the Entity vector. (Not ideal) Create bindings between C++ and a scripting language. This would seem to get the job done, but it feels like implementing this (given the potential memory overhead) and learning a new language is overkill for a small team (2-3 people) that know the entirety of the existing game engine. Can you suggest any possible alternatives? My ideal situation would be that to add content to the game, one would simply add a script file to the appropriate directory and append the SQLite database with all the object data. All that is required is to have a variety of integers and floats passed between both the engine and the script file.

• Can static and dynamically typed languages be seen as different tools for different types of jobs?

  - by Erik Reppen

  Yes, similar questions have been asked but always with the aim of finding out 'which one is better.' I'm asking because I came up as a dev primarily in JavaScript and don't really have any extensive experience writing in statically typed languages. In spite of this I definitely see value in learning C for handling demanding operations at lower levels of code (which I assume has a lot to do with static vs dynamic at the compiler level), but what I'm trying to wrap my head around is whether there are specific project contexts (maybe certain types of dynamic data-intensive operations?) involving things other than performance where it makes a lot more sense to go with Java or C# vs. something like Python.

• How can I quantify the amount of technical debt that exists in a project?

  - by Erik Dietrich

  Does anyone know if there is some kind of tool to put a number on technical debt of a code base, as a kind of code metric? If not, is anyone aware of an algorithm or set of heuristics for it? If neither of those things exists so far, I'd be interested in ideas for how to get started with such a thing. That is, how can I quantify the technical debt incurred by a method, a class, a namespace, an assembly, etc. I'm most interested in analyzing and assessing a C# code base, but please feel free to chime in for other languages as well, particularly if the concepts are language transcendent.

• Should I return iterators or more sophisticated objects?

  - by Erik

  Say I have a function that creates a list of objects. If I want to return an iterator, I'll have to return iter(a_list). Should I do this, or just return the list as it is? My motivation for returning an iterator is that this would keep the interface smaller -- what kind of container I create to collect the objects is essentially an implementation detail On the other hand, it would be wasteful if the user of my function may have to recreate the same container from the iterator which would be bad for performance.
