It's now been over four years since the release of 0.11 alpha and it couldn't unfortunately have been any different. But today I'm finally able to offer you the minimum feature set and quality that you've been waiting for.<br />
<i style="text-align: center;"><br /></i>
<i style="text-align: center;">Oh-Eleven</i><span style="text-align: center;"> brings you syntax highlighting on the result display, predefined color schemes, instant function usage help, digit grouping (thanks, Tey), new languages, a slightly redesigned formula book with new sections, lots of visual perks, and a new icon (by yours truly, who decided to take an adventure in vector graphics). You can now include comments in the expression - everything after a question mark (</span><i style="text-align: center;">?</i><span style="text-align: center;">) will be ignored and highlighted differently. Finally, bot comma and dot are now accepted as radix characters. Check the complete closed list of </span><a href="https://code.google.com/p/speedcrunch/issues/list?can=1&q=Milestone%3D0.11+Type%3DEnhancement+status%3AFixed+&colspec=ID+Type+Status+Priority+Milestone+Owner+Summary&cells=tiles" style="text-align: center;">enhancements</a><span style="text-align: center;"> and </span><a href="https://code.google.com/p/speedcrunch/issues/list?can=1&q=Milestone%3D0.11+Type%3DDefect+status%3AFixed&colspec=ID+Type+Status+Priority+Milestone+Owner+Summary&cells=tiles" style="text-align: center;">defects</a><span style="text-align: center;">.</span><br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://speedcrunch.org/images/slide1.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" src="http://speedcrunch.org/images/slide1.png" height="240" width="320" /></a></div>
Now for some bad news for some of you: the virtual keypad is gone. The reason for this is that it goes against the SpeedCrunch philosophy and main goal - to be a keyboard-oriented, fast to use scientific calculator. The old keypad was both ugly and not very functional. I'll consider re-adding a keypad in the future IFF a significant user base asks for it and a good and scalable design is found. I see this feature in the same category and usefulness as RPN support.<br />
<span style="text-align: center;"><br /></span>
<span style="text-align: center;">I'm already thinking about 0.12 (or 1.0) and the features that should have priority. One of them is the long awaited ability to define user functions. Thanks to Tey, we're getting there and it will certainly be available in the next version. But for now, I hope you'll enjoy and find this release useful. Grab your Windows or OS X package from the </span><a href="http://speedcrunch.org/" style="text-align: center;">usual place</a><span style="text-align: center;">, which has just been heavily revamped. Linux users will have to wait for their distribution to update their included version.</span><br />

If the term <a href="http://en.wikipedia.org/wiki/Software_release_life_cycle#Alpha">alpha</a> does not ring a bell for you, please be aware that it might contain numerous bugs.<br /><br />Although it should function quite well for the majority of users, the goal of this release is precisely to give people a new version to play with and report back the issues encountered during usage.<br /><br />You can give us feedback through our <a href="http://groups.google.com/group/speedcrunch/">mailing list</a>, but if you are sure about the existence of a bug, please fill it on our <a href="http://code.google.com/p/speedcrunch/issues/">bug tracker</a>.<br /><br />I apologize for the lack of a proper and up-to-date change log, but you can check most of the changes <a href="http://code.google.com/p/speedcrunch/issues/list?can=7&q=milestone:0.11&colspec=ID+Type+Status+Priority+Milestone+Owner+Summary&cells=tiles">here</a>.

I haven't forgotten about it though. Will try to include them for the final 0.11, but can't promise. Also, there are some old requests still not implemented in this version, so if your particular wish matches that case, I'm sorry for that.<br /><br />Like usually, contributors of any kind are more than welcome to help this project (developers, translators, testers, etc). Please feel free to participate in our mailing list or contact me directly.<br /><br />Special thanks to Alessandro, Andreas, Ariya and Wolf, who help me in keeping this project alive despite the slow progress in the past year.<br /><br />Only the links are missing:<br /><li><a href="http://speedcrunch.googlecode.com/files/SpeedCrunch-0.11-alpha.exe">Installer for Microsoft Windows</a></li><li><a href="http://speedcrunch.googlecode.com/files/SpeedCrunch-0.11-alpha.zip">Portable Edition for Microsoft Windows </a></li><li><a href="http://speedcrunch.googlecode.com/files/SpeedCrunch-0.11-alpha.dmg">Apple Mac OS X Universal application </a></li><li><a href="http://speedcrunch.googlecode.com/files/speedcrunch-0.11-alpha.tar.gz">Source code tarball</a></li><br />I hope that the new features, user interface tuning and new translations please you, as well as the bugs fixed.

The lastest release, 0.10.1 (May 24), has a Portable Edition download count of almost 11000 as I write this (<a href="http://code.google.com/p/speedcrunch/downloads/list">source</a>).<br /><br />But since August 22, our fellow folks at PortableApps.com have incorporated SpeedCrunch in their distribution (<a href="http://portableapps.com/apps/office/speedcrunch_portable">page</a>). This is absolute good business for us, since the download count is at this moment a bit above 47000 (<a href="http://sourceforge.net/project/showfiles.php?group_id=151265&package_id=288703">source</a>).<br /><br />This is quite impressive and gives SpeedCrunch yet another boost, since it basically doubles our Windows (installable and portable together) download rates for 0.10.1. A big thank you to portableapps.com!Helder Correiahttp://www.blogger.com/profile/06430233725902328852noreply@blogger.com2tag:blogger.com,1999:blog-3899900022788320858.post-72581838987654317682008-08-02T00:07:00.003+01:002008-08-02T01:18:15.467+01:00Essential Motivation in Free SoftwareBeing really tired to code anything on a Friday evening while the TV tries to force me to watch Dick Tracy in vain, I decided to do a web search on reviews about SpeedCrunch.<br /><br />I was surprised with the amount of recent articles about 0.10.1, complete with screenshots and non-copied-and-pasted text. I quickly found some 20 posts, and that was just looking for pages in English, Portuguese and Spanish. Articles in Spanish and Brazilian Portuguese are quite common for some time (thank you everybody responsible for that!), but today I got really touched when I found a very nice page with a review from someone from Portugal for the first time. The feeling is even bigger when one lives outside the home country.<br /><br />I haven't found a review saying SpeedCrunch essentially sucks so far, and the opinions are actually VERY favorable. On top of that, readers often comment on those pages thanking for the divulgation of such great alternative free software. The voting score is also generally the highest possible.<br /><br />So in addition to blogs, some of the websites were software aggregators that actually host the application files (they don't just link to our download page). That was when I found out by summing the few that I visited, that I could add at least 10 000 downloads to our counter (which is currently around 22 000, just for both Windows options). Well, considering all the websites that I didn't visit, and that every download eventually results, in average, in the sharing with the whole family / friends / office mates / class mates / you-name-it-group-of-people, I truly believe that the current amount of users (again, just for the Windows versions) can be, at the very least, 100 000.<br /><br />Since SpeedCrunch is also available on almost all the most popular Linux distributions, and especially considering that it is shipped as the default desktop calculator in Kubuntu, the total number of users is probably extremely interesting for a project that started only as a toy and a proof of concept, and has always been a 1-2 active men project (active as in when the rare spare time after the real job and private life allows). The recent recovered support for the OSX platform also contributed for the increase of total official downloads, which surprised me a lot, to be honest.<br /><br />Finally, it's also very gratifying to read Wikipedia pages mentioning our beloved pet project, on articles like <a href="http://en.wikipedia.org/wiki/Division_by_zero">division by zero</a> and <a href="http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic">arbitrary-precision arithmetic</a>. All of these factors are quite important in order to keep the motivation levels high and refuse to stop improving the project because nobody really uses it or really cares.<br /><br />It's fairly easy to start a free software project, but maintaining it is a hell of a trip. On activity peak times, you can't just stop coding until you reach a certain satisfactory level of features and stability. After that period, you run out of ideas and free time. So people suddenly come to you and complain about bugs or features that MUST be there, otherwise the product is useless and the author a jerk. This can easily lead to the extinction of projects, which is probably the most common destiny of them all anyway.<br /><br />Developers must then learn how to ignore destructive comments and incentivate constructive ones, instead of starting flame wars, stalling the project and wasting precious time. Feature suggestion and bug reporting are two essential and determinant factors that only the users can do, and will definitely contribute for the survival of a project. I imagine that if what has been happening with the KDE Plasma project lately happened with a "small", innocent and unpretentious SpeedCrunch, the application would probably have frozen in time. All because ingratitude and destructive positions send real contributers' motivation to the void.<br /><br />So thank you for being there and keeping this project alive and kickin' :)Helder Correiahttp://www.blogger.com/profile/06430233725902328852noreply@blogger.com9tag:blogger.com,1999:blog-3899900022788320858.post-40022862787390654902008-06-02T23:15:00.003+01:002008-06-05T08:18:57.881+01:00SpeedCrunch 0.10.1 releasedIt took much longer than it should and than we all wished, but finally here it is. SpeedCrunch 0.10.1 is a maintenance release that aims to fix a couple of annoying bugs present in 0.10, as well as introduce new translations and polish things even more.<br /><br />So finally the virtual keypad "=" button <a href="http://code.google.com/p/speedcrunch/issues/detail?id=176&can=1&q=milestone:0.10.1">works again</a>, the previous and next math book navigation buttons <a href="http://code.google.com/p/speedcrunch/issues/detail?id=185&can=1&q=milestone:0.10.1">have been fixed</a> for the Hebrew version (for those who don't know, the left arrow means "forward" instead of "back" in right-to-left written languages), and the unmask function <a href="http://code.google.com/p/speedcrunch/issues/detail?id=180&can=1&q=milestone:0.10.1">does not crash</a> anymore.<br /><br />Since I'm a language and translation lover, I'm very glad to announce the availability of Simplified Chinese, Basque and Catalan translations. Best thing since the Hebrew translation :)<br /><br />For the geeks, a detailed changelog <a href="http://speedcrunch.googlecode.com/svn/tags/0.10.1/ChangeLog">is available</a>, as well as the list of <a href="http://code.google.com/p/speedcrunch/issues/list?can=1&q=milestone%3A0.10.1&colspec=ID+Type+Status+Priority+Milestone+Owner+Summary&cells=tiles">closed issues</a> in our task tracker.<br /><br />I kept the cherry for the end: a big thank you to Alessandro Portale for providing the first Apple Mac OS X universal package since version 0.7, and Christian Ehrlicher for providing faster and smaller Microsoft Windows packages.<br /><br />Go <a href="http://speedcrunch.org">get it</a>!

I was immediately convinced that this has to be the open source cross platform desktop calculator. But wait... what's that!? No up-to-date OSX package? Just having learned about SpeedCrunch, I immediately felt bad for all the OSX users out there being excluded from all the new features.<br /><br />Having basic OSX experience, I decided to jump on the boat and create fresh OSX packages: Universal binary, compact and using the latest Qt. SpeedCrunch 0.10.1 will already come with a new OSX package.<br /><br />You are welcome to test the <a href="http://www.casaportale.de/lagerraum/SpeedCrunch-0.10.1-Preview.dmg">preview version</a>. Please let me know if something went wrong. I am for example not 100% sure if it runs on OSX 10.3.9.<br /><br />If you like to build an OSX package yourself, just follow the <a href="http://code.google.com/p/speedcrunch/wiki/BuildingOSXPackage">instructions</a>.Alessandro Portalehttp://www.blogger.com/profile/11866823172844198050noreply@blogger.com0tag:blogger.com,1999:blog-3899900022788320858.post-8966399842133865152008-04-01T21:38:00.008+01:002008-04-02T12:49:27.842+01:00SpeedCrunch 0.10 Released!After about 4 months of very strong dedication (and I mean it), a new version is out there. You can get it as usual from the project website <a href="http://www.speedcrunch.org/en/download.htm">download page</a>. NOTE: now there is also a portable edition available in addition to the normal installer, please read the instructions on the page. There, you can also read the major changes in this version (box on the right). If you're really interested, you can always read the <a href="http://speedcrunch.googlecode.com/svn/tags/0.10/ChangeLog">changelog</a> or, why not, the list of all the bug fixes and enhancements registered in the <a href="http://code.google.com/p/speedcrunch/issues/list?can=1&q=status%3AFixed%2CVerified+milestone%3A0.10&colspec=ID+Type+Status+Priority+Milestone+Owner+Summary&cells=tiles">issue tracker</a>.<br><br />My personal very favorite new features are:<ul><li>the ability to calculate, inside an immediate tooltip, the result of the selected text (in addition to the calculate-as-you-type feature that SpeedCrunch introduced a long time ago)</li><br /><li>the possibility to save and restore sessions, keeping your variables between them. It also makes it possible for you to send your calculations to someone. In addition, it is also possible to run a batch calculation from a file, as well as the text export that was broken in the previous version</li><br /><li>the ability to change the language of the application on-the-fly, with no need to restart, as well as a close to complete support for right-to-left written languages (Hebrew, for now, but I'd love to be contacted by an arabic or whatever translator)</li><br /><li>automatic generation of high contrast colors to be used on the syntax highlighting of the expression being entered, adapting automatically to the system background and foreground colors, thus removing the need for a human (tedious) reconfiguration of the colors</li><br /><li>a new dock window serving as a browsable mathematics manual, with geometry figures, quadratic equation, etc, allowing the immediate insertion of the formulas displayed in the book pages into the expression editor</li><br /><li>reorganized menus and virtual keypad</li><br /></ul>I need to mention this. There's a sort of an "easter egg" in SpeedCrunch that just a few people seem to know about. If you press Ctrl+Space, you'll get a popup with all the constant categories. If you press Enter, Return or Right Arrow on one of them, a new view will slide in the popup - the list of constants belonging to the category you chose. Pretty handy for those who use the calculator through the keyboard and need frequent and fast access to the constants they need.<br /><br />I'd like to say a huge thank you to Wolf Lammen for his active development, especially on the math engine and parser; Petri Damstén for his original idea of the math book and prototype implementation; Marco Wegner for his testings, tips and work related on our translation tools; Yonathan Avraham for his help on the RTL support; Johan Thelin for being always available to help me with my deep questions about Qt and packaging the application on Windows; Ariya Hidayat, the original author, for his important contributions on the last days and what not (and we both started working for Trolltech today, life's funny sometimes, hurray!).<br /><br /><br />I hope you enjoy the new release, it should be the most complete and polished release ever.<br />For the Linux users, a dynamically linked portable edition will be shipped soon as well (that shall work on any Linux distribution with Qt 4.2 or higher version), and requiring no installation, just like the new Windows Portable Edition.

The new (optional, as almost everything else in the application) status bar and the new automatically generated syntax hilighting colors are shown. Not shown is the new feature that allows the user to select a part of the expression being inserted and get its result immediately in a tooltip (just like calc-as-you-type). The math book also got a new style sheet. I hope that in the future we can adapt it automatically to the system colors as well (the only tricky part is to make images adaptive).Helder Correiahttp://www.blogger.com/profile/06430233725902328852noreply@blogger.com0tag:blogger.com,1999:blog-3899900022788320858.post-33584303806181085962008-02-21T21:37:00.020+00:002008-02-25T13:50:02.717+00:00Generating syntax highlighting colors based on system colorsFor quite some time it came to my mind that the colors used for syntax highlighting should be automatically generated by the application, removing the need of forcing the user to manually edit each and every color everytime a new color scheme is chosen for the whole system. In the SpeedCrunch case, there's at least the need of choosing 3 colors for the expression editor syntax highlighting: variables, functions and numerals.<br /><br />The problem is when the text box background or the text color is not the expected (generally white and black, respectively). So I started playing with some code in order to try to reach an easy and acceptable enough algorithm that could make SpeedCrunch adapt to any text and background color combinations (or at least the most common and wise ones). Certainly, predefined color sets (that also include and overwrite the system background and text colors) shall always be provided, in order to ensure that nobody needs to switch off syntax highlighting.<br /><br />Let's look at the examples. The surrounding color represents the system base color, used for text input boxes, for instance. The first colored square represents the system text color. The remaining squares are the generated colors for highlighting. If you see no surrounding color, that's because it's white.<br /><br />KDE / Windows * / MacOs X / BeOS<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh9QoNIcaa-fMU18vurKUbBCbS-yfJxj3folUVRss6kdEI8IdUZ-HPfktCEaHZyMEsL8zAGLDCcz0hgN9jA04Emd03OWd5-wYyfLi4JhUMSVLIx2Xxd7oeR4zUAtmiohQC-o9y_cFuEZ3U/s1600-h/autohilite-kde-windows-macosx-beos.png"><img style="cursor:pointer;

In the example, we can see a page for the quadratic equation. Currently there are additional pages for various 2D and 3D objects. If you want to contribute with more pages to enrich our book, just contact us. Physics and other areas are also welcome, not only plain mathematics. The pages are trivial to design (you can easily do it with the lamest text editor). We'll help you out with your first one. I must say they are also translatable (I always try to make sure everything is translatable :) So the book will be available in other languages, just like the rest of the application.<br /><br />In 0.10 it will also be possible to run SpeedCrunch in full screen mode (additionally to the stay-always-on-top mode). The mathematical core was also very much reworked and is better than ever. There are plans to introduce rational and complex numbers to the application. Not sure if for 0.11 or later, since 0.11's main focus will be a complete port for KDE4. Also still possible to be ready for 0.10 is the "portable" (as in take it with you) build. So then you just need to copy a directory to your flash drive and run your favorite calculator anywhere :)Helder Correiahttp://www.blogger.com/profile/06430233725902328852noreply@blogger.com2tag:blogger.com,1999:blog-3899900022788320858.post-11848532958889813732008-01-14T22:23:00.000+00:002008-01-14T22:44:26.521+00:00SpeedCrunch with Oxygen style<p><a href="http://code.google.com/p/speedcrunch/issues/detail?id=126">Work</a> is continuing to bring <a href="http://www.speedcrunch.org">SpeedCrunch</a> closer to become a real KDE 4 application.

SpeedCrunch has several dock widgets and I thought that some kind of math book widget would be nice. After mockup got positive feedback I wrote something to start with. Since writing simple browser with QTextBrowser is an easy job, that did not take long. When talking to Helder Correia he noted that this could be a more general book widget that could also show help etc. I think the result look promising especially considering how little time it took to make it :-)<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrsDDHh7qmNpxivDCbmzaHeQI71Hwng9tnNj1ssHBsn6p3qKensuhVZF_nOviC9UUSZ3HodTBOBm949U9Lnt-ZHrhJoHbXHVW0icjV6gfNBG876paUFS3eqX4kfsb6NPg7onUaBgVjXy0/s1600-h/speedcrunch_book.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjrsDDHh7qmNpxivDCbmzaHeQI71Hwng9tnNj1ssHBsn6p3qKensuhVZF_nOviC9UUSZ3HodTBOBm949U9Lnt-ZHrhJoHbXHVW0icjV6gfNBG876paUFS3eqX4kfsb6NPg7onUaBgVjXy0/s400/speedcrunch_book.png" alt="" id="BLOGGER_PHOTO_ID_5143755921915925890" border="0" /></a><br /><span style="font-size:85%;"> (This post can also be found from my <a href="http://pdamsten.blogspot.com/2007/12/math-book.html">blog</a>)</span>Petri Damsténhttp://www.blogger.com/profile/09787740330194013628noreply@blogger.com1tag:blogger.com,1999:blog-3899900022788320858.post-56387795423824833402007-12-12T00:26:00.000+00:002007-12-12T00:37:40.397+00:00Feature plan for 0.10Finally I took some time to write down all the <a href="http://code.google.com/p/speedcrunch/wiki/FeaturePlan">features</a> I'm aiming for the next <a href="http://code.google.com/p/speedcrunch/wiki/ReleaseSchedule">release</a>.

About half of the improvements and fixes that were planned will have to be shifted to another release. Lately, the developers' professional and private lives have been taking all of the former usual spare time because of its higher priorities. Nevertheless, this version brings some cool enhancements.<br />Of those, I'd like to mention the absolutely extraordinary work of the new developer Wolf Lammen, who has integrated a new, faster, more accurate and stable math core into SpeedCrunch. The usual new functions and a <i>stay always-on-top</i> window feature are also some of the news.<br />So it is now time for the call for translators. The current version is available in <a href="http://speedcrunch.blogspot.com/2007/07/would-anyone-like-to-contribute.html">16 languages</a>. For this release, I'd like to extend this number. So if you want to contribute to this project with a new or updated translation, you're very welcome to do so. Please drop a comment on this article or on our Google Groups forum. You just need to know how to use Trolltech's <a href="http://trolltech.com/products/qt/features/internationalization">Qt Linguist 4</a>.<br />Here's the up-to-date list of languages already being taken care of by someone:<br /><b>de | es_AR | fi | fr | he | id | it | nl | pt | pt_BR | ru | sv</b>Helder Correiahttp://www.blogger.com/profile/06430233725902328852noreply@blogger.com0tag:blogger.com,1999:blog-3899900022788320858.post-7126813019781805562007-07-29T18:31:00.000+01:002007-07-29T18:40:41.991+01:00A nice reviewAriya found <a href="http://kernelsource.org/2007/07/27/speedcrunch-la-calculadora-mas-precisa/">this interesting review</a> (in Spanish). I've translated it to English so most of you can understand it (may not be a perfect translation though, since I'm native portuguese and not spanish):<br /><blockquote><tt><br />"Although any operating system comes with a calculator, its characteristics go no further beyond common calculations. If we need more precise results or execute calculations with certain complexity, we shall consider SpeedCrunch as a magnificent tool. It's a calculator program with some very interesting features like scrolling display, up to 50 decimal digits precision, unlimited variable storage, intelligent automatic completion or additional math functions. Using it is very pleasant since we can customize the look, and we can deal with big expressions with no problem because of the syntax highlighting and parenthesis matching. It's an option to consider when traditional solutions are not enough and we don't want to use other GNU/Linux complex calculation tools."</tt></blockquote>Helder Correiahttp://www.blogger.com/profile/06430233725902328852noreply@blogger.com4tag:blogger.com,1999:blog-3899900022788320858.post-9143432881925286262007-07-26T12:39:00.000+01:002007-07-28T16:17:46.739+01:00SpeedCrunch 0.9 release planFirst of all, I'd like to say that a maintenance 0.8.1 release might be considered if some critical bugs are found meanwhile. And now...0.9.<br /><br />We've already got a lot of <a href="http://code.google.com/p/speedcrunch/wiki/FeaturePlan">improvements and bug fixes</a> in mind, so let's define the goals and deadlines for the next major 0.9 release codenamed <i>Nona</i> (spelled Noh-na and meaning ninth in Portuguese :)<br /><br />I learned a lot from 0.8's process, since it was my very first FOSS release. Many mistakes were made and I hope to fix them for Nona. Also, SpeedCrunch has lately won a great number of contributors (enhancement proposals, testing, bug fixing, translations). And so I had a lot of trouble coordinating everybody, accomplishing deadlines and managing bug reports and patches.<br /><br />For the upcoming release, I'd love to increase the number of active contributors. Maybe Johan can come back to active development now that he's finished his <a href="http://www.apress.com/book/bookDisplay.html?bID=10278">book on Qt 4</a>. Maybe Wolf can help in other fields other than his very promising new math engine. Maybe someone else new can come and help in order to achieve an even bigger boost. And of course I guess we can always count on our old daddy (guess who) to help us from time to time when he's resting from KOffice and his PhD :)<br /><br />So <a href="http://code.google.com/p/speedcrunch/wiki/ReleaseSchedule">here's the plan</a>, based on my recent experience. And it's really meant to be respected, else I'll end up e.g. fixing translations by hand over and over til the very last moment before the release, just like it happened this time.
