• Should you always pass the bare minimum data needed into a function

  - by Anders Holmström

  Let's say I have a function IsAdmin that checks whether a user is an admin. Let's also say that the admin checking is done by matching user id, name and password against some sort of rule (not important). In my head there are then two possible function signatures for this: public bool IsAdmin(User user); public bool IsAdmin(int id, string name, string password); I most often go for the second type of signature, thinking that: The function signature gives the reader a lot more info The logic contained inside the function doesn't have to know about the User class It usually results in slightly less code inside the function However I sometimes question this approach, and also realize that at some point it would become unwieldy. If for example a function would map between ten different object fields into a resulting bool I would obviously send in the entire object. But apart from a stark example like that I can't see a reason to pass in the actual object. I would appreciate any arguments for either style, as well as any general observations you might offer. I program in both object oriented and functional styles, so the question should be seen as regarding any and all idioms.

• IPv6 tunnels - any easy way to turn them on and off?

  - by Rob Hoare

  I've set up a tunnelbroker.net (Hurricane Electric) IPv6 tunnel from my laptop running 12.04. Works fine, and allows me to test the dual-stack configuration on my remote webservers etc. until native IPv6 is available on my ISP. However, there are times when I don't want the tunnel. For example if I'm accessing something that requires an IPv4 address in my own country rather than the Tunnelbroker tunnel endpoint, or if I'm away from the local IPv4 tunnel endpoint, or if I simply want to test without IPv6. Is there a simple way to disable and then re-enable the IPv6 tunnel, without rebooting? For context, here's what's in my /etc/network/interfaces (NNN replaces numbers): auto he-ipv6 iface he-ipv6 inet6 v4tunnel endpoint 216.218.NNN.NNN address 2001:470:NNN:NNN::2 netmask 64 up ip -6 route add default dev he-ipv6 down ip -6 route del default dev he-ipv6 Is there a network manager application (gui or command line) to selectively enable/disable parts of /etc/network/interfaces, or IPv6 in general? I found even by commenting out that out (and reloading networking) it's tough to get the IPv6 to go away. A "tunnel on/off" button in networking would be great, like using a VPN.

• Windows 8 App Downloads Increasing + Over 5,000 Apps Available

  - by David Paquette

  Windows 8 will be unleashed on the general public tomorrow and I thought it would be a good time to review some of the numbers I have been tracking over the last month. Downloads of Windows 8 Apps have been steadily increasing over the last month.  Below is screenshot from the App Summary page for my Windows 8 app.  The blue line is my app, while the orange line is average for the top 5 apps in that subcategory.  Considering the large gap between the 2, I think it is safe to assume that my app is NOT in the top 5 in the subcategory. The spike in the last couple of days is fairly dramatic and I am a little surprised by that.  I would have expected that kind of spike on the days following the official release as opposed to the days leading up to the release.   Finally, the all important App count.  There have been some stories floating around that the Window 8 Store is a ghost town and that there are no apps available.  I think these might be exaggerating the situation a little.  As of this morning, in the US store there are over 5000 apps available for download.  Obviously a far cry from the hundreds of thousands available in other app stores, but we are seeing solid growth in this number. Less than a month ago, that number was 2000. That means the store more than doubled in less than a month. If the growth continues, it won’t be long before the Widows 8 Store is filled with all the apps you need (and a whole lot you don’t need).

• Is there an application that converts a PC into a video game kiosk/arcade machine?

  - by Rahil627

  Sorry to make the question so vague. What I ultimately want is software that allows people to play independent video games on a PC and not have to worry about maintaining it. Imagine a game that was made in a few hours that does not have a restart button and crashes often. It should be able to handle these kinds of things and do more! The software should: allow the game to be restarted manually handle game crashes (likely by restarting the game) restrict the user from doing anything crazy later... offer a UI to select the game from a list handle pre-configured key bindings cross-platform (start with windows) I just want to know if this exists already before I start creating one. As of now AutoHotKey is being used to do this sloppily. If such software does not exist then perhaps someone could recommend a general open source Kiosk software? Open Kiosk? I'll take anything. (I also could not find a related tag. Not even sure if this question should be here rather than stackoverflow)

• "Viral" license that only blocks legal actions of user and developer against each other

  - by Lukasz Zaroda

  I was thinking a lot about software licensing lately, because I would like to do some coding. I'm not an expert in all those licenses, so I came up with my own idea, and before I will put in on paper, I would like to make sure that I didn't reinvent a wheel, so maybe I would be able to use something that exists. Main idea behind my license is to guarantee freedom of use the software, but not "freedom to" (positive) (e.g. freedom to having source code), but "freedom from" (negative) (strictly from legal actions against you). It would be "viral" copyleft license. You would be able to without fear do everything you want with the software (and binaries e.g. reverse engineering), as long as You will include information about author and/or authors, and all derivative works will be distributed with the same license. I'm not interested in anything that would restrict a freedom of company to do something like "tivoization". I'm just trying to accomplish something that would block any legal actions of user and developer, targeted against each other, with the exception of basic attribution. Does exist something like that?

• What is logical cohesion, and why is it bad or undesirable?

  - by Matt Fenwick

  From the c2wiki page on coupling & cohesion: Cohesion (interdependency within module) strength/level names : (from worse to better, high cohesion is good) Coincidental Cohesion : (Worst) Module elements are unrelated Logical Cohesion : Elements perform similar activities as selected from outside module, i.e. by a flag that selects operation to perform (see also CommandObject). i.e. body of function is one huge if-else/switch on operation flag Temporal Cohesion : operations related only by general time performed (i.e. initialization() or FatalErrorShutdown?()) Procedural Cohesion : Elements involved in different but sequential activities, each on different data (usually could be trivially split into multiple modules along linear sequence boundaries) Communicational Cohesion : unrelated operations except need same data or input Sequential Cohesion : operations on same data in significant order; output from one function is input to next (pipeline) Informational Cohesion: a module performs a number of actions, each with its own entry point, with independent code for each action, all performed on the same data structure. Essentially an implementation of an abstract data type. i.e. define structure of sales_region_table and its operators: init_table(), update_table(), print_table() Functional Cohesion : all elements contribute to a single, well-defined task, i.e. a function that performs exactly one operation get_engine_temperature(), add_sales_tax() (emphasis mine). I don't fully understand the definition of logical cohesion. My questions are: what is logical cohesion? Why does it get such a bad rap (2nd worst kind of cohesion)?

• Benefits of Masters of Engineering Professional Practice for the lowly (yet aspiring) programmer

  - by Peter Turner

  I've been looking into in state online degree programs 'to fit my busy lifestyle' (i.e. three children, wife and hour and a half commute). One interesting one I've found is that Master of Engineering in Professional Practice. It looks more useful and practical than a MBA in project management. I'll contact the admission dept there about the specifics. But here I'm just asking in general. Do the courses in this degree apply to software engineering/development in even an abstract sense. The university I'm looking at does not have a Software Engineering major in the school of engineering. I'm not interested in architecture astronomy, but I am interested in helping my company succeed and being able to communicate technical information at a high and effective level as well as being able to lead my co-programmers toward a more robust end product. So my multipart question is: What might be the real benefit to me and my brain and How do I convince my boss (the owner of the company, who does do some tuition reimbursement) that just because it doesn't say anything about software that it might still do us some good? Oh, and how do I get past the fact that a masters degree would make me more qualified to be the project manager than... the project manager? (who is my supervisor)

• Slap the App on the VM for every private cloud solution! Really ?

  - by Anand Akela

  One of the key attractions of the general session "Managing Enterprise Private Cloud" at Oracle OpenWorld 2012 was an interactive role play depicting how to address some of the key challenges of planning, deploying and managing an enterprise private cloud. It was a face-off between Don DeVM, IT manager at a fictitious enterprise 'Vulcan' and Ed Muntz, the Enterprise Manager hero .   Don DeVM is really excited about the efficiency and cost savings from virtualization. The success he enjoyed from the infrastructure virtualization made him believe that for all cloud service delivery models ( database, testing or applications as-a-service ), he has a single solution - slap the app on the VM and here you go . However, Ed Muntz believes in delivering cloud services that allows the business units and enterprise users to manage the complete lifecycle of the cloud services they are providing, for example, setting up cloud, provisioning it to users through a self-service portal ,  managing and tuning the performance, monitoring and applying patches for database or applications. Watch the video of the face-off , see how Don and Ed address some of the key challenges of planning, deploying and managing an enterprise private cloud and be the judge ! ?

• OAuth2 vs Public API

  - by Adam Tannon

  My understanding of OAuth (2.0) is that its a software stack and protocol to allow 2+ web apps to share information about a single end user. User A is a member of Site B and Site C; Site B wants to fetch some data from Site C about User A, and this is where OAuth steps in. So first off, if this assessment is incorrect, please begin by clarifying this for me and correcting me! Assuming I'm on the right track, then I guess I'm not seeing the need for OAuth to begin with (!). I'm sure I'm just not seeing the "forest through the trees" here, but the way I see it, couldn't Site C just expose a public API that Site B could use to fetch the same data (sans OAuth)? If Site C required user credentials to access the data, could this public API just use HTTPS for secure transport and require username/password as a part of each API call? Again, I'm sure I'm missing something, but I'm just not understanding why I would need OAuth when a secure, public API written and exposed by Site C seems more than capable of delivering what Site B needs regarding User A. In general, I'm looking for a set of guidelines to go by when deciding to choose between using OAuth for my web apps or just writing my own web service ( exposing public API). Thanks in advance!

• Modular Database Structures

  - by John D

  I have been examining the code base we use in work and I am worried about the size the packages have grown to. The actual code is modular, procedures have been broken down into small functional (and testable) parts. The issue I see is that we have 100 procedures in a single package - almost an entire domain model. I had thought of breaking these packages down - to create sub domains that are centered around the procedure relationships to other objects. Group a bunch of procedures that have 80% of their relationships to three tables etc. The end result would be a lot more packages, but the packages would be smaller and I feel the entire code base would be more readable - when procedures cross between two domain models it is less of a struggle to figure which package it belongs to. The problem I now have is what the actual benefit of all this would really be. I looked at the general advantages of modularity: 1. Re-usability 2. Asynchronous Development 3. Maintainability Yet when I consider our latest development, the procedures within the packages are already reusable. At this advanced stage we rarely require asynchronous development - and when it is required we simply ladder the stories across iterations. So I guess my question is if people know of reasons why you would break down classes rather than just the methods inside of classes? Right now I do believe there is an issue with these mega packages forming but the only benefit I can really pin down to break them down is readability - something that experience gained from working with them would solve.

• https:// search results appearing on Google for purely http:// site

  - by hydrurga

  I started weeding through my site's search results from Google today, using a site: search, to determine if there are any links that cause 404s and thus need redirecting. To my amazement I noticed numerous https:// results relating to various pages. My site doesn't have a SSL certificate, doesn't serve such pages, doesn't internally link to https:// pages, doesn't include any such files in its sitemap.xml and, for all of these, never has. I decided to do a Google search for https://<my site> and found one site that incorrectly refers to the root of my site with a https:// prefix - I will try to contact them to get them to correct this. I'm not sure however how Googlebot managed to index the non-root files as https://. I can't find any external links to them and surely, without certification, Googlebot should have stalled at the first request? I've just added the following lines to the site's .htaccess (although the surfer still has to navigate through the browser's "This site is a security risk. Abandon hope all ye who enter here!" message(s) first to get there): RewriteEngine On RewriteCond %{HTTPS} on RewriteRule ^(.*)$ http://www.<my site>.org/$1 [R=301,L] replacing <my site> with my domain name. My big question is this though - I would like to use the Google Webmaster Tools Remove URLs feature to remove the https:// pages from the index. Can I be guaranteed that this will only remove the https:// versions of each relevant page and not the valid http:// versions? My thanks to anyone who can help me out with this particular question and the issue in general.

• The Enterprise Side of JavaFX: Part Two

  - by Janice J. Heiss

  A new article, part of a three-part series, now up on the front page of otn/java, by Java Champion Adam Bien, titled “The Enterprise Side of JavaFX,” shows developers how to implement the LightView UI dashboard with JavaFX 2. Bien explains that “the RESTful back end of the LightView application comes with a rudimentary HTML page that is used to start/stop the monitoring service, set the snapshot interval, and activate/deactivate the GlassFish monitoring capabilities.”He explains that “the configuration view implemented in the org.lightview.view.Browser component is needed only to start or stop the monitoring process or set the monitoring interval.”Bien concludes his article with a general summary of the principles applied:“JavaFX encourages encapsulation without forcing you to build models for each visual component. With the availability of bindable properties, the boundary between the view and the model can be reduced to an expressive set of bindable properties. Wrapping JavaFX components with ordinary Java classes further reduces the complexity. Instead of dealing with low-level JavaFX mechanics all the time, you can build simple components and break down the complexity of the presentation logic into understandable pieces. CSS skinning further helps with the separation of the code that is needed for the implementation of the presentation logic and the visual appearance of the application on the screen. You can adjust significant portions of an application's look and feel directly in CSS files without touching the actual source code.”Check out the article here.

  - by William Pursell

  I've just come across (for the 47 millionth time) some code that looks like this: except IOError, e: print "Problems reading file: %s." % filename sys.exit( 1 ) My first reaction is very visceral: the person who coded this is a complete idiot. How hard is it to print error messages to stderr and to include the system error message in the string? I haven't used python in years, and it took me all of 4 minutes to track down the documentation to figure out how to get the error message from the exception object e and the syntax for printing to stderr. My "complete idiot" reaction was slightly lessened since at least a non-zero value is passed to sys.exit, but I still find this code offensive. My prime thought is that the developer who wrote this is a complete novice for whom I have zero respect. Am I over-reacting? Surely there are excuses for all sorts of bad coding practices, but is there anything that can possibly excuse this sort of $#|t? I guess there are two question here: one is a duplicate of What are developer's problems with helpful error messages?, and the other is "am I over-reacting, or is it valid to conclude that the author of the above code is a novice?"

• What is a Coding Dojo?

  - by huwyss

  Recently i found out that there is a thing called "coding dojo". The point behind it is that software developers want to have a space to learn new stuff like processes, methods, coding details, languages, and whatnot in an environment without stress. Just for fun. No competition. No results required. No deadlines.Some days ago I joined the Zurich coding dojo. We were three programmers with different backgrounds.We gave ourselves the task to develop a method that takes an input value and returns its prime factors. We did pair programming and every few minutes we switched positions. We used test driven development. The chosen programming language was Ruby.I haven't really done TDD before. It was pretty interesting to see the algorithm develop following the testcases.We started with the first test input=1 then developed the most simple productive program that passed this very first test. Then we added the next test input=2 and implemented the productive code. We kept adding tests and made sure all tests are passed until we had the general solution.When we improved the performance of our code we saw the value of the tests we wrote before. Of course our first performance improvement broke several tests.It was a very interesting experience to see how other developers think and how they work. I will participate at the dojo again and can warmly recommend it to anyone. There are  coding dojos all over the world.Have fun!

• Is there such thing as a "theory of system integration"?

  - by Jeff

  There is a plethora of different programs, servers, and in general technologies in use in organizations today. We, programmers, have lots of different tools at our disposal to help solve various different data, and communication challenges in an organization. Does anyone know if anyone has done an serious thinking about how systems are integrated? Let me give an example: Hypothetically, let's say I own a company that makes specialized suits a'la Iron Man. In the area of production, I have CAD tools, machining tools, payroll, project management, and asset management tools to name a few. I also have nice design space, where designers show off their designs on big displays, some touch, some traditional. Oh, and I also have one of these new fangled LEED Platinum buildings and it has number of different computer controlled systems, like smart window shutters that close when people are in the room, a HVAC system that adjusts depending on the number of people in the building, etc. What I want to know is if anyone has done any scientific work on trying to figure out how to hook all these pieces together, so that say my access control system is hooked to my payroll system, and my phone system allowing my never to swipe a time card, and to have my phone follow me throughout the building. This problem is also more than a technology challenge. Every technology implementation enables certain human behaviours, so the human must also be considered as a part of the system. Has anyone done any work in how effectively weave these components together? FYI: I am not trying to build a system. I want to know if anyone has thoroughly studied the process of doing a large integration project, how they develop their requirements, how they studied the human behaviors, etc.

• Oracle E-Business Suite is Helping to Save Lives at the National Marrow Donor Program

  - by Di Seghposs

  To improve the management of its life-saving operations, the National Marrow Donor Program recently modernized its financial and procurement operations by upgrading to Oracle E-Business Suite 12.1.   As the global leader in bone marrow and umbilical cord blood transplants, the NMDP manages a complex ecosystem of donor, patient, hospital, and biological data. “Maintaining accurate data and having an efficient matching process is essential, particularly as our global database of bone marrow patients grows and donor lists expand,” says Bruce Schmaltz, director of finance/controller. “We rely on the Oracle E-Business Suite to ensure our procurement and financial management processes meet the highest standards, enabling our growing non-profit to work swiftly and efficiently to help improve and save lives.” As the non-profit organization and its registry grew larger, NMDP needed a modern platform to store and integrate its financial information and complicated procurement process. It selected Oracle E-Business Suite for its ability to fit seamlessly into NMDP’s enterprise architecture. NMDP initially implemented Oracle E-Business Suite release 12 by leveraging Oracle Business Accelerators, which are rapid implementation tools and templates that help reduce implementation time and costs. With Oracle Financial Management and Oracle Procurement, NMDP has streamlined back-office processes and integrated its procure-to-pay business processes by leveraging industry leading accounts payable, accounts receivable, and general ledger modules. NMDP is currently rolling out Oracle Hyperion Performance Management applications and plans to implement Oracle Order Management and Oracle Advanced Pricing by the end of 2012. Read more details about NMDP’s modernization efforts.  For more updates on Oracle Financial Management Solutions, view our November 2012 Oracle Information InDepth Financial Management newsletter. Subscribe Now.

• What reasons are there to reduce the max-age of a logo to just 8 days? [closed]

  - by callum

  Most websites set max-age=31536000 (1 year) on the Cache-control headers of static assets such as logo images. Examples: YouTube Yahoo Twitter BBC But there is a notable exception: Google's logo has max-age=691200 (8 days). I've checked the headers on the Google logo in the past, and it definitely used to be 1 year. (Also, it used to be part of a sprite, and now it is a standalone logo image, but that's probably another question...) What could be valid technical reasons why they would want to reduce its cache lifetime to just 8 days? Google's homepage is one of the most carefully optimised pages in the world, so I imagine there's a good reason. Edit: Please make sure you understand these points before answering: Nobody uses short max-age lifetimes to allow modifying a static asset in future. When you modify it, you just serve it at a different URL. So no, it's nothing to do with Google doodles. Think about it: even if Google didn't understand this basic trick of HTTP, 8 days still wouldn't be appropriate, as only those users who don't have the original logo cached would see the doodle on doodle-day – and then that group of users would go on seeing the doodle for the following 8 days after Google changed it back :) Web servers do not worry about "filling up" the caches of clients (or proxies). The client manages this by itself – when it hits its own storage limit, it just starts dropping the lowest priority items to make space for new items. The priority score is based on the question "How likely am I to benefit from having cached this URL?", which is nothing to do with what max-age value the server sent when the URL was originally requested; it's a heuristic based on the "frecency" of requests for that URL. The max-age simply lets the server set a cut-off point – the time at which the client is supposed to discard the item regardless of how often it's being re-used. It would be very nice and trusting of a downstream client/proxy to rely on all origin servers "holding back" from filling up their caches, but I don't think we live in that world ;)

• Ubuntu 64bit Black Screen on Minecraft

  - by Signify

  I have tried posting on the forums, but I really need help (I'm a server admin and really don't want to have to switch to Windows just to run Minecraft). Anyhow, I originally was running openjdk6 as I was told that 7 was unstable and was getting periodical lag spikes while walking (at least once every 3 seconds the screen would freeze for a tenth of a second). After that, I attempted to install Sun's Java JDK7 (I couldn't get ahold of 6 without signing up for Oracle's newsletters). Upon attempting to run Minecraft, I got a black screen after logging in with this error message: 27 achievements 182 recipes Setting user: Thunder7102, -1618112820878091307 Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/noiro/.minecraft/bin/natives/liblwjgl.so: /home/noiro/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1939) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1864) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1825) at java.lang.Runtime.load0(Runtime.java:792) at java.lang.System.load(System.java:1059) at org.lwjgl.Sys$1.run(Sys.java:69) at java.security.AccessController.doPrivileged(Native Method) at org.lwjgl.Sys.doLoadLibrary(Sys.java:65) at org.lwjgl.Sys.loadLibrary(Sys.java:81) at org.lwjgl.Sys.<clinit>(Sys.java:98) at org.lwjgl.opengl.Display.<clinit>(Display.java:132) at net.minecraft.client.Minecraft.a(SourceFile:184) at net.minecraft.client.Minecraft.run(SourceFile:657) at java.lang.Thread.run(Thread.java:722) Now, this got me fed up, so I tried to install a Windows 7 virtual machine through virtualbox, I gave it 256mb of graphics memory with 2D and 3D acceleration and 3GB of RAM. I installed Java JDK7 for Windows (which does work from experience on my other Windows 7 partition). Once again, a black screen after login. What the heck is going on guys? My System Specs: Ubuntu 12.04 64bit Fully Updated running Gnome3 Nvidia GTS 450 1.3GB OC'd AMD Athlon II 4x 2.8Ghz 6GB of RAM So, what do you think?

• What are some efficient ways to set up my environment when working on a remote site?

  - by Prefix

  Hello fellow Programmers, I am still a relatively new programmer and have recently gotten my first on-campus programming position. I am the sole dev responsible for 8 domains as well as 3 small sized PHP web apps. The campus has its web environment divided into staging and live servers -- we develop on the staging via SFTP and then push the updates to the live server through a web GUI. I use Sublime Text 2 and the Sublime SFTP plugin currently for all my dev work (its my preferred editor). If I am just making an edit to a page I'll open that individual file via the ftp browser. If I am working on the PHP web app projects, I have the app directory mapped to a local folder so that when I save locally the file is auto-uploaded through Sublime SFTP. I feel like this workflow is slow and sub-optimal. How can I improve my workflow for working with remote content? I'd love to set up a local environment on my machine as that would eliminate the constant SFTP upload/download, but as I said there are many sites and the space required for a local copy of the entire domain would be quite large and complex; not to mention keeping it updated with whatever the latest on the staging server is would be a nightmare. Anyone know how I can improve my general web dev workflow from what I've described? I'd really like to cut out constantly editing over FTP but I'm not sure where to start other than ripping the entire directory and dumping it into XAMP.

• How does a game developer get feedback from gamers (not developers) or start a forum community without paying for advertising or hiring Q&A teams?

  - by Carter81

  I am familiar with a lot of game developer forums, but I'd assume this is much less likely to attract more casual commentators. I also fear that feedback from a gamer's perspective would often be tainted by their game dev perspective. For example, if I were making a RTS game and wanted to get feedback from "The RTS gamers" where would I go? Is there a general idea of what type of website or forum to go to? Do you go to specific game websites, to try to "steal" attention? Would this not equate to spam or inappropriate posting? What is considered appropriate and inappropriate? I am not asking for specifics. I am asking how one "starts a community", or how one "gets feedback from gamers" without resorting to spamming forums or 'advertising' just to see what sticks. What TYPE OF PLACE does one go? Are there already sites designed for this purpose? I tried going to what was once a very popular forum for feedback from what I believed was a niche hardcore group of gamers in the genre, but its popularity seemed to have died significantly; Leaving only trolls and very young teenagers. The resulting feedback was quite disappointing, mainly for how little feedback it resulted. Many years ago, feedback would flood in by the hundreds so quickly. Without this website, I am at a loss as to where to go to see what people think of ideas, gather feedback from a gamer's perspective (not a developer's perspective), or where to pull from to start my own site's forum. I am out of ideas of what to do, short of going to various game forums to post in the off-topic sections there.

• Hash Algorithm Randomness Visualization

  - by clstroud

  I'm curious if anyone here has any idea how the images were generated as shown in this response: Which hashing algorithm is best for uniqueness and speed? Ian posted a very well-received response but I can't seem to understand how he went about making the images. I hate to make a new question dedicated to this, but I can't find any means to ask him more directly. On the other hand, perhaps someone has an alternative perspective. The best I can personally come up with would be to have it almost like a bar graph, which would illustrate how evenly the buckets of the hash table are being generated. I have a working Cocoa program that does this, but it can't generate anything like what he showed there. So the question is two fold I suppose: A) How does one truly interpret the data he shows? Is it more than "less whitespace = better"? B) How does one generate such an image based on some set of inputs, a hash, and an index? Perhaps I'm misunderstanding entirely, but I really would like to know more about this particular visualization technique. Or maybe I'm mis-applying this to hash tables rather than just hashes in general, but in that case I don't know how it would be "bounded" for the image.

• PerlRegEx vs RegularExpressionsCore Delphi Units

  - by Jan Goyvaerts

  The RegularExpressionsCore unit that is part of Delphi XE is based on the latest class-based PerlRegEx unit that I developed. Embarcadero only made a few changes to the unit. These changes are insignificant enough that code written for earlier versions of Delphi using the class-based PerlRegEx unit will work just the same with Delphi XE. The unit was renamed from PerlRegEx to RegularExpressionsCore. When migrating your code to Delphi XE, you can choose whether you want to use the new RegularExpressionsCore unit or continue using the PerlRegEx unit in your application. All you need to change is which unit you add to the uses clause in your own units. Indentation and line breaks in the code were changed to match the style used in the Delphi RTL and VCL code. This does not change the code, but makes it harder to diff the two units. Literal strings in the unit were separated into their own unit called RegularExpressionsConsts. These strings are only used for error messages that indicate bugs in your code. If your code uses TPerlRegEx correctly then the user should not see any of these strings. My code uses assertions to check for out of bounds parameters, while Embarcadero uses exceptions. Again, if you use TPerlRegEx correctly, you should never get any assertions or exceptions. The Compile method raises an exception if the regular expression is invalid in both my original TPerlRegEx component and Embarcadero’s version. If your code allows the user to provide the regular expression, you should explicitly call Compile and catch any exceptions it raises so you can tell the user there is a problem with the regular expression. Even with user-provided regular expressions, you shouldn’t get any other assertions or exceptions if your code is correct. Note that Embarcadero owns all the rights to their RegularExpressionsCore unit. Like all the other RTL and VCL units, this unit cannot be distributed by myself or anyone other than Embarcadero. I do retain the rights to my original PerlRegEx unit which I will continue to make available for those using older versions of Delphi.
