  • Removing .html and index.html from URL

    - by James Turner
    I'm having some problems trying to Remove the .html extension from URLs Removing 'index.html' from an URL 1) To remove the extension I have tried using this in my htaccess file. RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(.*)$ $1.html However when I click links in my HTML such as <a href="abcde.html"></a> it doesn't remove the .html from the URL and I am left with www.website.com/abcde.html 2) I tried using this to remove the index.html RewriteCond %{THE_REQUEST} \/index\.(php|html)\ HTTP [NC] RewriteRule (.*)index\.(php|html)$ /$1 [R=301,L] But when I load an index.html file on my server, my URL looks something like this www.website.com/folder// I am left with an extra / at the end. Can anyone help me out?

  • Is Code Complete still Code Complete? [closed]

    - by Peter Turner
    It's been quite a few years since Code Complete was published. I really love the book, I keep it in the bathroom at the office and read a little out of it once or twice a day. But I don't think it's possible to call Code Complete, "Code Complete" when it doesn't have language features that even Delphi has, like anonymous methods and generics. What key sections are missing from this book, and what should be deprecated?

  • What tools do you use to stay focused?

    - by Peter Turner
    This is related, but I'm thinking about something more like a chastity belt for keeping me from checking programmers.SE or my email every time I compile. Rather advice like "go take a walk and you'll feel more like coding", I just need something to augment my weak constitution - a net nanny for my geek fetish I guess. I'll take my answer off the air and I promise not to check programmers.SE for at least a day.

  • What do neglected O'Reilly book topics tell us about that topic?

    - by Peter Turner
    Does anybody know how O'Reilly chooses topics to publish? For some reason, I don't see how it can be based on demand. The reason, I ask, is because they haven't published a Delphi book in almost 12 years and Object Pascal is at least as esoteric as Erlang and as practical as PHP and as robust as C++. So, maybe someone knows what rationale is behind O'Reilly's publishing methodology or what it is supposed to tell us about the relative popularity or usefulness of any given language or programming technique? Oh, I forgot about pig and robotlegs

  • Is there any way to stop a window's title bar merging with the panel when maximised?

    - by Richard Turner
    I'm working on a desktop machine with plenty of screen real-estate, so I don't need my windows' title bars to merge with the global menu bar when the windows are maximised. Moreover, I'm working on a dual-screen set-up, so the fact that a window is maximised doesn't mean that it's the only window visible. Before Unity I'd switch to a maximised window by clicking on its title bar, or close the window, even though it isn't focused, by clicking on its close button; I can no longer do this because the title bar is missing and the global menu bar is empty on that screen. This isn't a huge problem - I can click on some of the window's chrome to focus it - but it's unintuitive and it's forcing me to relearn my mousing behaviour. I'd like to turn-off the merging of title and global menu bars, but how? EDIT: I simply want the title bar of the window NOT to merge with the top panel whenever I maximize a Window. The global menu should stay in the top panel as far as I am concerned. Current it maximizes like this I want it to maximize like this (In that screeny the unmaximized Window has been resized to take rest of the space)

  • How to negotiate with software vendors who do not follow HL7 standards

    - by Peter Turner
    Take, for instance the "", I'd hope that anyone who has spent any time in dealing with HL7 messages knows that the "" signifies that something should be deleted. "" is not an empty string, it's not a filler etc... But occasionally, one may meet a vendor who persists in sending "" instead of just sending nothing at all. Since, I work for a small business and have an extremely flexible HL7 interface, I can ignore ""'s in received messages. But these things are adding up. Some vendors like to send custom formatted fields with psuedo-components that they leave others to interpret themselves. Some vendors send all their information in note segments and assume you're going to only show users the information they send in a monospace font. Some vendors even have the audacity to send Carriage Return Line Feeds at the end of each line of a file interface. Some vendors absolutely refuse to send decimal numbers and in-so-doing refuse to send any numbers. So, with all this crippling humanity against the simple plastic software man, how does one bend without breaking*? Or better yet, how does one fight back and still make money? *my answer is usually to create an interface for the interface and keep the HL7 processing pure, but I don't think this is the best solution

  • As a code monkey, how to discuss programming with a guy who almost has a doctorate in computer science

    - by Peter Turner
    A friend of my wife's is coming over for dinner tonight and he is a lot smarter than me. What do we have in common, well... A Bachelor's in Computer Science, and that should be enough of a conversation starter. But he's nearly completed his doctoral studies and is light years ahead of me in his particular area, which I find fascinating but don't have any legit reason to care about (except for maybe a better way through heavy traffic - he's a combinatorics guy specializing in that I think) and I got married and had some kids and am a professional programmer for medical records software. We've got a lot in common, but there's a point where neither of us care or understand each other - although I really want to learn from him and I'm not certain he'd even want to talk about his work. So for all you doctors or code monkeys, what's a good conversation starter!

  • Is the HL7 membership model normal?

    - by Peter Turner
    To me, it's a little odd that HL7 requires you to be a member to distribute the standard within your organization and in that sense implement the standard and tell others who have implemented the standard what parts you'll be implementing, especially when it's nothing classier than a few pipes and carets for 2.x and some sort of XML for 3.0. I can understand paying money to use a library to utilize HL7 or even the source code to build the library to utilize HL7. But what's the point of requiring membership to see the spec to write the sourcecode to build the library to utilize HL7?

  • Why did Embarcadero make me sign a waiver?

    - by Peter Turner
    Just signed in to the Embarcadero Developer Network and got this: EXPORT CONTROLS ON EMBARCADERO SOFTWARE Your EDN membership and access to Embarcadero Software is subject to your agreement to and compliance with the following terms: -You agree that U.S. export control laws govern your use of the Embarcadero Software. -You are not a citizen, national, or resident of, and are not under control of, the government of Cuba, Iran, Sudan, North Korea, Syria, nor any country to which the United States has embargoed or prohibited export. -You will not provide or export Embarcadero Software, directly or indirectly, to the above mentioned countries nor to citizens, nationals or residents of those countries. -You are not listed on the United States Department of Treasury lists of Specially Designated Nationals, Specially Designated Terrorists, and Specially Designated Narcotic Traffickers, nor are you listed on the United States Department of Commerce Table of Denial Orders. -You will not provide or export the Embarcadero Software, directly or indirectly, to persons on the above mentioned lists. -You will not use the Embarcadero Software for, and will not allow the Embarcadero Software to be used for, any purposes prohibited by United States law, including for the development, design, manufacture or production of nuclear, chemical or biological weapons of mass destruction. I think it's BS, but what craziness is forcing companies like Embarcadero to hold developers to these very high standards? Also, what is "Embarcadero Software"? Does that mean I can't put a benign videogame on a website that may have a runtime that might be downloaded by a Iranian who love scrabble. Or does "Embarcadero Software" refer to anything I develop using Delphi.

  • Windows Phone 7 DatePicker gotcha

    - by David Turner
    The Silverlight Toolkit for Windows Phone adds some great extra controls for Windows Phone 7, one gotcha that I ran into was that the DatePicker Application Bar icons don’t show up unless you include them in your project. The problem is that your DatePicker ends up looking like this: Tim Heuer mentions this in his blog post about the Silverlight Toolkit for WP7, and as he says, it is documented in the source code: So the problem is that the icons can’t be referenced from the Silverlight Toolkit Assembly, and the solution is that you have to add them to you project in the ‘well known’ / pre-defined location of a top level folder in your project called Toolkit.Content, and you must make sure to mark the icons with a Build Action of  ‘Content’ otherwise it wont work: The result is that your DatePicker will now look like this:

  • Grad school guides for professional programmers

    - by Peter Turner
    I've exhausted my googling abilities on this search (too many ad-sites peddling online degrees) and turned to my favorite resource, ya'll. I'm looking for a website, book or long winded answer that breaks down graduate programs at universities and colleges by their geographical area / online capability; relative cost; prestige; difficulty; applicability to software engineering, computer science or a project management MBA; and years to complete.

  • Good abbreviations for XML ... things

    - by Peter Turner
    I've never been very good at maintaining a coherent bunch of variable names for interfacing with XML files because I never name the variables in my interfaces the same way across my source. There are Elements, Attributes, Documents, NodeLists, Nodes, DocumentFragments and other stuff. What's a good scheme for keeping track of this stuff as variables? Is there a standard in regard to Hungarian notation? Do you even put anything signifying that the data is actually XML, is this bad practice?

  • Codeigniter + JQuery + Processing.js to replace a Delphi App

    - by Peter Turner
    So, I've got a mandate to make our aged trillion lined Delphi app web based and it needs to make heavy use of the <canvas> element (HTML5 compatibility doesn't seem to be a big issue since we can just make our clients use a compatible browser the way we'd make them use a compatible version of Windows in the win32 environment). The Delphi app in question is almost completely database driven and will still pretty much continue to be developed as the main product. What I am tasked with is pretty much recreating a scaled down version of the program that performs the major functions of the whole program. I couldn't find any frameworks that simulate windows forms using the canvas element, I'm assuming this is probably by design since it is easier just to use HTML, well, be that as it may, I still think it would be cool to have a few of my cool controls on the web (TRichView and TVirtualTree, etc...) So my question is, to anyone who has tried this before, A.) What can we use for an IDE to code this web app (I just use emacs, but no one else in my company does)? B.) Is it a good idea to mix PHP and Processing.JS? It seems like I'm using a lot of AJAX to get anything to happen. 3 calls just for one dialog box to pop up, Loads the HTML for the dialog, Loads the XML to populate the database info on the form Loads the processing.js PJS file which draws the database info to the canvas. Is three a lot, do people usually combine all their gets into one?

  • Who would be the most efficacious Patron Saint of Programmers? [closed]

    - by Peter Turner
    The purpose of this question is to find someone out there to intercede for us and help our coding (not to magically align the bytes), to inspire our daily grind of software development by their lives of heroic virtue, to unite us under a common patron and to keep us on the straight and narrow path (i.e. don't be evil). In days of yore, the professional guilds had a patron saint. Regardless of whether we have a higher tendency to be atheists or not, who would you choose as the patron saint of programmers and what would be your criteria? Some people have chosen St. Isidore of Seville, but he's more like the patron saint of Wikipedia. If you're not Catholic please don't hesitate to nominate someone, just say what your criteria is. At the very least they should be dead and have lived a life of heroic virtue - or have died trying. It's a very pragmatic and noble custom which I heartily encourage. But if you find the practice off-putting, please don't be offended. I only mean to ask this question to other like minded programmers, which I have reason to believe exist. If you add a picture and a maybe make up a prayer that'd be excellent. It doesn't have to be gilded, illuminated and rhyme, although that would be sweet.

  • Windows Phone 7 Development &ndash; Useful Links

    - by David Turner
    Here are some excellent links for anyone developing for Windows Phone 7: J.D. Meier’s Windows Phone Developer Guidance Map – this is immense.  Also check out the Silverlight version Justin Angel’s site – some really great articles on unlocked roms, automation and Continuous Integration Windows Phone 7 Development Best Practices Wiki Jeff Blankenburg’s 31 days of Windows Phone 7 This post of Links to sample code for Windows Phone Tim Heuers blog, particularly this post of Tips and Tricks Kevin Marshall's blog, particularly the epic WP7 Development Tips Part 1 post Code Samples for Windows Phone on MSDN If you have unlocked your phone for development, then you can use the WPConnect tool to connect to the device rather than using the Zune client.  I found it useful to pin a shortcut to WPConnect in my Start Menu. The Performance Counters displayed when you debug your app on a device are useful for seeing things like frame rate and memory usage, this page on MSDN explains what the numbers mean.  Jeff Blankenburg covers this in more details on his blog I also came across this set of links to tutorials recently which looks very useful.

  • What would you add to Code Complete 3rd Edition?

    - by Peter Turner
    It's been quite a few years since Code Complete was published. I really love the book, I keep it in the bathroom at the office and read a little out of it once or twice a day. I was just wondering for the sake of wonderment, what kinds of things need to be added to Code Complete 3e, and for the sake of reductionism, what kinds of things would be removed. Also, what languages would you use for code examples?

  • What's better than outputdebugstring for windows debugging?

    - by Peter Turner
    So, before I came to my current place of employment, the windows OutputDebugString function was completely unheard of, everyone was adding debug messages to string lists and saving them to file or doing showmessage popups (not very useful for debugging drawing issues). Now everybody (all 6 of us) is like "What can I say about this OutputDebugString?" and I'm like, "with much power comes much responsibility." I kind of feel as though I've passed a silent but deadly code smell to my colleagues. Ideally we wouldn't have bugs to debug right? Ideally we'd have over 0% code coverage, eh? So as far as petty debugging is concerned (not complete rewriting of a 3 million line Delphi behemoth) what's a better way to use debug running code than just adding OutputDebugString all over?

  • iOS Touch Icon through XLSX file?

    - by Joe Turner
    I'm setting up some iPads, and pointing Safari to www.mywebsite.com/spreadsheet.xlsx and it's displaying the document fine. That part is OK. I'm just wondering if there is a way to add a iOS Icon to the document so I can save it to the springboard of the iPad? Maybe embedding the document in HTML? PHP could also possibly be used but I'm really not sure how I would go about doing this, has anyone managed anything like this before?

  • Memory concerns while plotting escape from DLL Hell in Delphi

    - by Peter Turner
    I work on a program with about 50 DLLs that are loaded from one executable, it's an old organically grown program where the only rationale for creating a new DLL is that one previously didn't exist to fill a given need. (and namespaces didn't exist in Delphi so it never crossed our mind to make dll1.main.pas, dll2.main.pas or something even more unique) What we want to do is consolidate all these DLLs into one executable, since none of them are used out of the program, there shouldn't be much of a problem. The concern my boss has is that if we did this, the memory overhead for terminal server clients would go through the roof. So, I've stepped through enough initialization code to know that lots of stuff is done every time a DLL is loaded in to memory, but say I've got a project with about 4000 files, and 50 dlls, 10 of which are probably utilized by any one user in any one session of the program. The 50 dlls are about 2/3rds form files, if not more, but beyond that there's not a lot of other resources being loaded (only a few embedded pictures, icons, cursors, etc..). If I loaded all these files in to memory, how much memory is used per unit? how much is used per class? How do I keep the overhead down? and what is the biggest project one can reasonably expect to build with Delphi? This tidbit won't help answering, but I think it might clarify what my boss is worried about, we currently start our program at about 18megs, normal working conditions are usually less than 40 megs, he thinks it could climb as high as 120 megs.

  • Should maven generate jaxb java code or just use java code from source control?

    - by Peter Turner
    We're trying to plan how to mash together a build server for our shiny new java backend. We use a lot of jaxb XSD code generation and I was getting into a heated argument with whoever cared that the build server should delete jaxb created structures that were checked in generate the code from XSD's use code generated from those XSD's Everyone else thought that it made more sense to just use the code they checked in (we check in the code generated from the XSD because Eclipse pretty much forces you to do this as far as I can tell). My only stale argument is in my reading of the Joel test is that making the build in one step means generating from the source code and the source code is not the java source, but the XSD's because if you're messing around with the generated code you're gonna get pinched eventually. So, given that we all agree (you may not agree) we should probably be checking in our generate java files, should we use them to generate our code or should we generate it using the XSD's?

  • What is a widely accepted term for a string variable that would probably contain a file path and file name?

    - by Peter Turner
    For functions that need to index files in a directory and rename them FileName0001, FileName0002, etc... I often need to write a function that splits the file name from the file path and rename the file. When I put the file name and file path back together, I don't have a very good name for the variable that contains both of them and I usually just wind up concatenating them every time I want to use them (usually using them as parameters for functions labeled either filename or filepath) so I never really know what I'm doing until I notice a lot of files being written in the same directory as my binaries. Anyway, what do I call a file name and a file path? I don't want to call it File, because that usually means the binary information behind the file. I don't want to call it URI because that usually means I've got some sort of protocol, which I don't. I just want a good way to denote "c:\somedir\somedir\somedir\somefile.txt" so as to deconfuse this mess I've just realized I'm in. Please don't just list your personal preference. I think an excellent answer should "'site its sources". (as in, provide a link to a repository with a good example of the code being used as I described)

  • Maximum file size for iFrame in IE7

    - by Peter Turner
    I've got a "super secure" javascript downloader* that I wrote, and it usually works alright. But I noticed, while trying to download a 90 meg file with it on a client's machine that on IE7, it's getting hung up about 1/3rd of the way through. I've never tried to send a file that large through the iFrame and it works fine in other browsers. Is there a size restriction on files that IE7 can read in an iFrame? * It's really just a PHP line that sets header("location: http://someplace/downloadbigthing.exe"); after it does some logging and verification.

  • What's the best language combo for code generation?

    - by Peter Turner
    I read through Code Generation in Action but never bothered to make anything of it because Ruby just doesn't fit with my lifestyle at this juncture. The book came out more on the cusp of the C# revolution, and it said that C# "was a language designed to be generated", apparently using Ruby as the generator language. In your experience, what is the ideal combination of languages to generate the most useful code?

  • SQL Constraints &ndash; CHECK and NOCHECK

    - by David Turner
    One performance issue i faced at a recent project was with the way that our constraints were being managed, we were using Subsonic as our ORM, and it has a useful tool for generating your ORM code called SubStage – once configured, you can regenerate your DAL code easily based on your database schema, and it can even be integrated into your build as a pre-build event if you want to do this.  SubStage also offers the useful feature of being able to generate DDL scripts for your entire database, and can script your data for you too. The problem came when we decided to use the generate scripts feature to migrate the database onto a test database instance – it turns out that the DDL scripts that it generates include the WITH NOCHECK option, so when we executed them on the test instance, and performed some testing, we found that performance wasn’t as expected. A constraint can be disabled, enabled but not trusted, or enabled and trusted.  When it is disabled, data can be inserted that violates the constraint because it is not being enforced, this is useful for bulk load scenarios where performance is important.  So what does it mean to say that a constraint is trusted or not trusted?  Well this refers to the SQL Server Query Optimizer, and whether it trusts that the constraint is valid.  If it trusts the constraint then it doesn’t check it is valid when executing a query, so the query can be executed much faster. Here is an example base in this article on TechNet, here we create two tables with a Foreign Key constraint between them, and add a single row to each.  We then query the tables: 1 DROP TABLE t2 2 DROP TABLE t1 3 GO 4 5 CREATE TABLE t1(col1 int NOT NULL PRIMARY KEY) 6 CREATE TABLE t2(col1 int NOT NULL) 7 8 ALTER TABLE t2 WITH CHECK ADD CONSTRAINT fk_t2_t1 FOREIGN KEY(col1) 9 REFERENCES t1(col1) 10 11 INSERT INTO t1 VALUES(1) 12 INSERT INTO t2 VALUES(1) 13 GO14 15 SELECT COUNT(*) FROM t2 16 WHERE EXISTS17 (SELECT *18 FROM t1 19 WHERE t1.col1 = t2.col1) This all works fine, and in this scenario the constraint is enabled and trusted.  We can verify this by executing the following SQL to query the ‘is_disabled’ and ‘is_not_trusted’ properties: 1 select name, is_disabled, is_not_trusted from sys.foreign_keys This gives the following result: We can disable the constraint using this SQL: 1 alter table t2 NOCHECK CONSTRAINT fk_t2_t1 And when we query the constraints again, we see that the constraint is disabled and not trusted: So the constraint won’t be enforced and we can insert data into the table t2 that doesn’t match the data in t1, but we don’t want to do this, so we can enable the constraint again using this SQL: 1 alter table t2 CHECK CONSTRAINT fk_t2_t1 But when we query the constraints again, we see that the constraint is enabled, but it is still not trusted: This means that the optimizer will check the constraint each time a query is executed over it, which will impact the performance of the query, and this is definitely not what we want, so we need to make the constraint trusted by the optimizer again.  First we should check that our constraints haven’t been violated, which we can do by running DBCC: 1 DBCC CHECKCONSTRAINTS (t2) Hopefully you see the following message indicating that DBCC completed without finding any violations of your constraint: Having verified that the constraint was not violated while it was disabled, we can simply execute the following SQL:   1 alter table t2 WITH CHECK CHECK CONSTRAINT fk_t2_t1 At first glance this looks like it must be a typo to have the keyword CHECK repeated twice in succession, but it is the correct syntax and when we query the constraints properties, we find that it is now trusted again: To fix our specific problem, we created a script that checked all constraints on our tables, using the following syntax: 1 ALTER TABLE t2 WITH CHECK CHECK CONSTRAINT ALL

  • What should developers know about Windows executable binary file compression?

    - by Peter Turner
    I'd never heard of this before, so shame on me, but programs like UPX can compress my files by 80% which is totally sweet, but I have no idea what the the disadvantages are in doing this. Or even what the compressor does. Website linked above doesn't say anything about dynamically linking DLLs but it mentions about compressing DESCENT 2 and about compressing Netscape 4.06. Also, it doesn't say what the tradeoffs are, only the benefits. If there weren't tradeoffs why wouldn't my linker compress the file? If I have an environment where I have one executable and 20-30 DLL's, some of which are dynamically loaded an unloaded fairly arbitrarily, but not in loops (hopefully), do I take a big hit in processing time decompressing these DLL's when they're used?
