For Your Inspection: Source Code For Photoshop 1.0 176

gbooch writes "With the permission of Adobe Systems, the Computer History Museum has made available the source code for Photoshop version 1.0.1, comprising about 128,000 lines of code within 179 files, most of which is in Pascal, the remainder in 68000 assembly language. This the kind of code I aspire to write. The Computer History Museum has earlier made available the source code to MacPaint."

Can You Do the Regular Expression Crossword? 115

mikejuk writes "Programmers often say that regular expressions are fun ... but now they can be a whole lot of fun in a completely new way. Want to try your hand at a regular expression crossword? The idea is simple enough — create a crossword style puzzle with regular expressions are the 'clues.' In case you don't know what a regular expression is — it is a way of specifying what characters are allowed using wild-card characters and more. For example a dot matches any single character, an * any number of characters and so on. The regular expression crossword is more a sort of Sudoku puzzle than crossword however because the clues determine the pattern that the entries in a row have to satisfy. It also has to use a hexagonal grid to provide three regular expressions to control each entry. This particular regular expression crossword(pdf) was part of this year's MIT Mystery Hunt. This annual event is crammed with a collection of very difficult problems and the regular expression crossword, created by Dan Gulotta from an idea by Palmer Mebane, was just a small part of the whole — and yes there is a solution."

Oracle Open Sourcing JavaFX, Including iOS and Android Ports 105

hypnosec writes "Oracle is going to open source JavaFX ports for Android and iOS soon as a part of its efforts to open source the framework. JavaFX, destined to replace Swing GUI library as the default method to develop graphical user interfaces, is a framework used to develop cross-platform rich Internet applications. The ports for iOS and Android are based on an 'unreleased version of JavaSE Embedded for iOS/Android.' Oracle's Richard Bair revealed that the 'first bits and pieces' for JavaFX for iOS should probably be out sometime next week. The rest of the release will be scheduled along with the release of Prism (the next-generation toolkit). Oracle is going to keep javafx-font proprietary, but Bair has said developers are already working toward an open source native replacement of the component through the OpenJFX list."

COBOL Will Outlive Us All 318

jfruh writes "Here's an old computer science joke: What's the difference between hardware and software? If you use hardware long enough, it breaks. If you use software long enough, it works. The truth behind that is the reason that so much decades-old COBOL code is out there still driving crucial applications at banks and other huge companies. Many attempts to replace COBOL applications flopped in the 1980s and '90s, and we're stuck with them for the foreseeable future — but the Baby Boomers who wrote all that code are now retiring en masse."

Ask Slashdot: Making Side-Money As a Programmer? 257

earlzdotnet writes "I've been programming for a few years now, and I have a full time job. I'm one of those lucky souls that actually enjoy programming, so I commonly work on my own open source projects on weekends. However, I wouldn't mind working on a short-term projects (i.e. not more than ~2 months) every once in a while on weekends. I've looked at freelancing before, and I could probably make more money by working at McDonald's on weekends than that. I've also looked into making web sites for small businesses, but it requires a bit too much commitment and support for me, especially since I'm terrible at graphics design. I've tried my hand at writing reusable components to sell to other programmers, but that was pretty pointless (I made one $20 sale). I've seen teaching suggested, but I'm self-taught and probably not experienced enough to responsibly teach people. Are there any other options to make a bit of cash as a programmer? Is programming just one of those things that requires complete dedication, or what?"

Should Techies Trump All Others In Immigration Reform? 231

theodp writes "In an open letter on TechCrunch, Vivek Wadhwa calls on Congressman Luis Gutierrez to lift his 'hold on Silicon Valley' and stop tying immigration reform for highly-skilled STEM immigrants to the plight of undocumented immigrants. So, why should the STEM set get first dibs? 'The issues of high-skilled and undocumented immigrants are both equally important,' says Wadhwa, but 'the difference is that the skilled workers have mobility and are in great demand all over the world. They are getting frustrated and are leaving in droves.' Commenting on Gutierrez's voting record, Wadhwa adds, 'I would have voted for visas for 50,000 smart foreign students graduating with STEM degrees from U.S. universities over bringing in 55,000 randomly selected high-school graduates from abroad. The STEM graduates would have created jobs and boosted our economy. The lottery winners will come to the U.S. with high hopes, but will face certain unemployment and misery because of our weak economy.' So, should Gutierrez cede to Wadhwa's techies-before-Latinos proposal, or would this be an example of the paradox of virtuous meritocracy undermining equality of opportunity?"

GNU Hurd To Develop SATA, USB, Audio Support 274

An anonymous reader writes "Hurd, the GNU micro-kernel project that was founded by Richard Stallman in 1983, may finally be catching up with Linux on the desktop... Plans were shared by its developers to finally bring in some modern functionality by working on support for Serial ATA drives, USB support, and sound cards. There are also ambitions to provide x86-64 CPU architecture support. GNU Hurd developers will be doing an unofficial Debian GNU/Hurd 'Wheezy' release this year but they hope for the Debian 'Jessie' release their micro-kernel in Debian will make it as part of some official CDs."

Crowdsourced Coders Take On Immunology Big Data 31

ewenc writes "Mercenary computer coders are helping scientists cope with the deluge of data pouring out of research labs. A contest to write software to analyze immune-system genes garnered more than 100 entries, including many that vastly outperformed existing programs. The US$6,000 contest was launched by researchers at Harvard Medical School and Harvard Business School, both in Boston, Massachusetts. TopCoder.com, a community of more than 400,000 coders who compete in programming competitions, hosted the contest. The results are described in a letter published this week in Nature Biotechnology."

Ask Slashdot: Do Most Programmers Understand the English Language? 330

Shadoefax writes "I have been developing Firefox add-ons for several years and all so far submitted to AMO have been translated (localized) into several different languages. My latest add-on is geared more to the web developer as opposed to the average web browsing user. (It is a utility for examining JavaScript Objects and their methods and properties.) By my reckoning, I believe JavaScript, HTML, CSS and the DOM are all pretty much designed to be easily understood by English language readers. My question is this: Can I assume that most programmers understand the English language well enough that I may forego localizing the UI? While this will save time, effort and bloat, it may also restrict the usage of (what I hope) is a useful tool for developers."

Summer Programming Courses Before Heading Off To College? 183

First time accepted submitter LiteWait writes "My son is heading off to college next year and although he is bright kid with a great background in math and science, he has indicated that he'd like learn some introductory programming skills this summer. The courses at the local universities are pretty sparse and most of the CS101-type courses I've seen offered are too general to meet his needs. Even though he is a self-starter I think he would benefit from actual courses/code camps/etc rather than just slogging through online samples and tutorials. I'd like some advice on possible options for code camps, online courses, or developer training."

Python Gets a Big Data Boost From DARPA 180

itwbennett writes "DARPA (the U.S. Defense Advanced Research Projects Agency) has awarded $3 million to software provider Continuum Analytics to help fund the development of Python's data processing and visualization capabilities for big data jobs. The money will go toward developing new techniques for data analysis and for visually portraying large, multi-dimensional data sets. The work aims to extend beyond the capabilities offered by the NumPy and SciPy Python libraries, which are widely used by programmers for mathematical and scientific calculations, respectively. The work is part of DARPA's XData research program, a four-year, $100 million effort to give the Defense Department and other U.S. government agencies tools to work with large amounts of sensor data and other forms of big data."

Ask Slashdot: Programming / IT Jobs For Older, Retrained Workers? 215

12_West writes "I seek opinions from the Slashdot community about entry level job opportunities as programmers (or other I.T. Staff) for seniors who want to switch careers and continue to work full time. I do not want to retire, nor go part time, as long as I can get up and drive myself in to work. I'm currently 58 years old, working as an industrial electrician in a maintenance department setting for a building products manufacturer. I like the work, but it is becoming hard on my aging body, so, I would like to begin gradually retraining and hope to switch careers in about four years. A lower paying, less physical job would be just fine as there will be pension money coming in. I'm not currently a programmer, but have done some hobbyist level coding in Qbasic and MS-DOS batch files 'back in the days.' I also have some exposure to the Rockwell Automation RSLogix programming tools that are now going obsolete. So, I will be retraining whether I switch careers or not."

The History of Visual Development Environments 181

Esther Schindler writes "There was a time when programs were written in text editors. And when competition between C++ vendors was actually fierce. Step into the time travel machine as Andy Patrizio revisits the evolution and impact of the visual development metaphor. 'Visual development in its earliest stages was limited by what the PC could do. But for the IBM PC in the early 1980s, with its single-tasking operating system and 8- or 16-bit hardware, the previous software development process was text edit, compile, write down the errors, and debug with your eyes.' Where do you start? 'While TurboPascal launched the idea of an integrated development environment, [Jeff] Duntemann credits Microsoft's Visual Basic (VB), launched in 1991, with being the first real IDE.'... And yes, there's plenty more." A comment attached to the story lists two IDEs that preceded VB; can you name others?

Gnome Goes JavaScript 387

mikejuk writes "Much to most programmers' shock and dismay Gnome has made JavaScript its main language for apps. It will still support other languages and it still supports C for libraries, but for apps it is JavaScript that rules. JavaScript seems to be a good choice for Gnome 3, as the shell UI is written in the language. It is also consistent with the use of JavaScript in WinRT, Chrome Apps, and FirefoxOS apps, and generally the rise of web apps. As you might expect, the initial reactions are of horror at the idea that JavaScript has been selected rather than the favorite language of the commenter. There is a great deal of ignorance about (and prejudice against) JavaScript, which is often regarded as an incomplete toy language rather than the elegant and sparse language that it actually is."

Apple Angers Mac Users With Silent Shutdown of Java 7 451

An anonymous reader writes in with news of the continuing saga of Java patches and exploits. "If you're a Mac user who suddenly can't access websites or run applications that rely on Java, you're not alone. For the second time in a month, Apple has silently blocked the latest version of Java 7 from running on OS X 10.6 Snow Leopard or higher via its XProtect anti-malware tool. Apple hasn't issued any official statements advising users of the change or its reasons, but it's a safe bet that the company has deemed Oracle's most recent update to Java insecure. That's why the company stealthily disabled Java on Macs back on Jan. 10, the same day a Java vulnerability was being exploited in the wild."

Can Proprietary Language Teams Succeed By Going Open Source? 136

JerkyBoy writes "RunRev maintains the proprietary LiveCode programming environment. Those familiar with HyperCard on the Mac would feel quite at home using the environment to produce simple applications, and possibly more, although the programming language it incorporates has a few significant shortcomings (e.g., true object orientation). But it is a very versatile environment, currently claiming support for Windows, Mac, Linux, iOS, Android, and server-side scripting. For us NOOBs who could never find the time to learn C++ and something like the wxWidgets or QT toolkits, it seems like a pretty good deal. Recently RunRev has done something interesting, however, and that is to create a Kickstarter campaign to move the environment to open source (~500K lines of code, ~700 files). The way that they describe it, it sounds like there will be a commercial version and an open-source version of the environment (hopefully not cripple-ware), and they are asking for money to do this. But I want to know: what are their chances of success with this model? How in the world can they make enough money to maintain their programmers and overhead while giving the environment away? In other words, if a company like RunRev announces that they are moving to an open-source model, should you become more interested or less interested in their product?"
