For Education, Why TI-83 > iPad 340

theodp writes "Writing in The Atlantic, Phil Nichols makes a convincing case for why educational technologies should be more like graphing calculators and less like iPads. Just messing around with TI-BASIC on a TI-83 Plus, Nichols recalls, 'helped me cultivate many of the overt and discrete habits of mind necessary for autonomous, self-directed learning.' So, with all those fancy iPads at their schools, today's kids must really be programming up a storm, right? Wrong. Nichols, who's currently pursuing a PhD in education, laments, 'The iPad is among the recent panaceas being peddled to schools, but like those that came before, its ostensibly subversive shell houses a fairly conventional approach to learning. Where Texas Instruments graphing calculators include a programming framework accessible even to amateurs, writing code for an iPad is restricted to those who purchase an Apple developer account, create programs that align with Apple standards, and submit their finished products for Apple's approval prior to distribution.'"

Ask Slashdot: Speeding Up Personal Anti-Spam Filters? 190

New submitter hmilz writes "I've been using procmail for years to filter my incoming mail, and over time a long list of spam patterns was created. The good thing about the patterns is, there are practically no false positives, and practically no false negatives, i.e. I see each new spam exactly once, and lose no legit mail. This works by using an external spam-patterns file, containing one pattern per line, and running an 'egrep -F' against it. As simple as this is, with a long pattern list this becomes rather slow and CPU consuming. An average mail currently needs about 15 seconds to be grepped. In other words, this has become quite clumsy over time, and I would like to replace it by a more (CPU, hence energy) efficient method. I was thinking about a small indexed database or something. What would you recommend and use if you were me? Is sqlite something to look at?"

Researchers Reverse-Engineer Dropbox, Cracking Heavily Obfuscated Python App 242

rjmarvin writes "Two developers were able to successfully reverse-engineer Dropbox to intercept SSL traffic, bypass two-factor authentication and create open-source clients. They presented their paper, 'Looking inside the (Drop) box' (PDF) at USENIX 2013, explaining step-by-step how they were able to succeed where others failed in reverse-engineering a heavily obfuscated application written in Python. They also claimed the generic techniques they used could be applied to reverse-engineer other Frozen python applications: OpenStack, NASA, and a host of Google apps, just to name a few..."

Devs Flay Microsoft For Withholding Windows 8.1 RTM 413

CWmike writes "Windows app developers are taking Microsoft to task for the company's decision to withhold Windows 8.1 until mid-October. Traditionally, Microsoft offers an RTM to developers several weeks before the code reaches the general public. On Tuesday, however, Microsoft confirmed that although Windows 8.1 has reached RTM, subscribers to MSDN will not get the final code until the public does on Oct. 17, saying it was not finished. Antoine Leblond, a Microsoft spokesman, said in a blog post, 'In the past, the release to manufacturing milestone traditionally meant that the software was ready for broader customer use. However, it's clear that times have changed.' Developers raged against the decision in comments on another Microsoft blog post, one that told programmers to write and test their apps against Windows 8.1 Preview, the public sneak peak that debuted two months ago. One commenter, 'brianjsw,' said, 'In the real world, developers must have access to the RTM bits before [general availability]. The fact that Microsoft no longer seems to understand this truly frightens me.'"

Ask Slashdot: How To Get Open Source Projects To Take Our Money? 301

New submitter wkaan writes "Last financial year, we had an underspend at work, and it was suggested and agreed that we should give some cash away — $20k to be exact — to open source projects. Four projects were selected. A management catch was that it could not appear to be a donation and it had to be for something we had notionally received in the current financial year. At that time it was early June, our financial year finishes at the end of June. The four projects were emailed using the most relevant looking contact address on their website. Often this was 'Finance' or 'Donations' contact. What do you know, none of the projects that were contacted could work out a way to accept our money. We were unable to give a cent of the twenty grand away, not even a cent. All somebody needed to do was invoice us for something (perhaps 'support' or whatever) and they'd have received $5000. Of the projects contacted, two never replied to our mail — perhaps they thought it a scam? The other two contacted couldn't work out what to invoice and just went away. Is open source too rich to need the money? Have you got a funny donation story? Better still, do you have a way this can be streamlined when we have our next underspend? The goal was not to have a funny (sad) story, but to support the projects that support our business." For those of you with open source projects for which would you would like to take donations but sometimes cannot, what complications get in the way?

Afraid Someone Will Steal Your Game Design Idea? 140

Lemeowski writes "Game studios go to great lengths to protect their IP. But board game designer Daniel Solis doesn't subscribe to that philosophy. He has spent the past ten years blogging his game design process, posting all of his concepts and prototypes on his blog. Daniel shares four things he's learned after designing games in public, saying paranoia about your ideas being stolen "is just an excuse not to do the work." His article provides a solid gut check for game designers and other creatives who may let pride give them weird expectations."

Write Windows Phone Apps, No Code Required 210

jfruh writes "One of the biggest challenges Microsoft has faced with its Windows Phone platform is that it's far behind in the apps race against iOS and Android. One way to close the gap is to lower the barrier to entry for new app devs, and Microsoft has done so with Windows Phone App Studio, a hosted service that lets you build applications without actually writing any code. The description of how App Studio works may leave you wondering how useful or exciting the apps created will be, but a surge of developer interest during the current beta program has surprised even Microsoft with its scope."

How One Programmer Is Coding Faster By Voice Than Keyboard 214

mikejuk writes "Is it possible that we have been wasting our time typing programs. Could voice recognition, with a little help from an invented spoken language, be the solution we didn't know we needed? About two years ago Tavis Rudd, developed a bad case of RSI caused by typing lots of code using Emacs. It was so severe that he couldn't code. As he puts it: 'Desperate, I tried voice recognition'. The Dragon Naturally Speaking system used by Rudd supported standard language quite well, but it wasn't adapted to program editing commands. The solution was to use a Python speech extension, DragonFly, to program custom commands. OK, so far so good, but ... the commands weren't quite what you might have expected. Instead of English words for commands he used short vocalizations — you have to hear it to believe it. Now programming sounds like a conversation with R2D2. The advantage is that it is faster and the recognition is easier — it also sounds very cool and very techie. it is claimed that the system is faster than typing. So much so that it is still in use after the RSI cleared up."

Web Apps: the Future of the Internet, Or Forever a Second-Class Citizen? 205

An anonymous reader writes "This article takes a look at whether web apps will ever match desktop and mobile apps in terms of performance and usability. Jo Rabin, who's leading the push by web standards body W3C to get web app performance up to scratch, is optimistic web apps will eventually be the default choice for building the majority of commercial and business apps, while the article weighs up just how much web technologies need to be improved before this could happen. Quoting: 'Native apps are generally first to gain access to new platform-specific hardware features — be it navigating using a phone's GPS and accelerometer or taking pictures with a phone's camera. But if a particular hardware feature becomes popular, standards to implement that feature in the browser will always follow, Rabin said. Work is taking place within W3C to standardise APIs for web technologies to access many of the features found on modern smartphones. Ongoing work this year includes setting out a system-level API to allow a web app to manage a device's contacts book, a messaging API for sending and receiving SMS and MMS, new mechanisms for capturing photos and recordings, new event triggers that could handle mouse, pen and touch inputs, a new push API to allow web apps to receive messages in the background, new media queries for responsive web design, an API for exchanging information using NFC and precise control over resource loading times in a web document.'"

Ask Slashdot: When Is It OK To Not Give Notice? 892

An anonymous reader writes "Here in the U.S., 'being professional' means giving at least two week's notice when leaving a job. Is this an outmoded notion? We've all heard stories about (or perhaps experienced) a quick escort to the parking lot upon giving the normal notice, and I've never heard of a company giving a two-week notice to an employee that's being laid off or fired. A generation ago, providing a lengthy notice was required to get a glowing reference, but these days does a reference hold water any more? Once you're reached the point where you know it's time to leave, under what circumstances would you just up and walk out or give only a short notice?"

Open Source Licensing Debate Has Positive Effect On GitHub 96

New submitter Lemeowski writes "Critics have been pounding GitHub recently, claiming it is hosting tons of code with no explicit software license. The debate was thrust into the limelight last year when James Governor of RedMonk issued an acclaimed tweet about young developers being 'about POSS — post open source software,' meaning they disliked or avoided licensing and governance. Red Hat's IP attorney Richard Fontana explores the complaint saying there is a positive aspect of the POSS and GitHub phenomenon: Developers are, for the first time in the history of free software, helping inform each other about licensing and aiding in the selection process. The result is that it's becoming easier to suggest legal improvements to GitHub-hosted repositories."

Larry Ellison Believes Apple Is Doomed 692

Nerval's Lobster writes "Oracle CEO Larry Ellison thinks that Apple will collapse without Steve Jobs at the helm. In a televised interview with CBS News, scheduled to air August 13, Ellison called the deceased Jobs 'brilliant' and compared him to iconic creators such as Thomas Edison and Pablo Picasso. When asked about Apple's future now that Jobs is dead, Ellison didn't hold back: 'We already know, we saw — we conducted the experiment, it's been done.' Raising his hand above his head, presumably to indicate the rise of Apple's fortunes during Jobs' initial reign, Ellison said: 'We saw Apple with Steve Jobs.' Then he lowered his hand: "We saw Apple without Steve Jobs." In other words, the period following Jobs' ouster, when the company's revenues declined and it launched whole portfolios of consumer products that failed. 'We saw Apple with Steve Jobs,' Ellison continued, raising his hand above his head again — this time, to suggest that incandescent period following Jobs' return to the company, when it released the iPod, iPhone, iPad, and a variety of bestselling PCs. 'And now, we're going to see Apple without Steve Jobs,' he finished, and his hand fell."

Back To 'The Future of Programming' 214

theodp writes "Bret Victor's The Future of Programming (YouTube video; Vimeo version) should probably be required viewing this fall for all CS majors — and their professors. For his recent DBX Conference talk, Victor took attendees back to the year 1973, donning the uniform of an IBM systems engineer of the times, delivering his presentation on an overhead projector. The '60s and early '70s were a fertile time for CS ideas, reminds Victor, but even more importantly, it was a time of unfettered thinking, unconstrained by programming dogma, authority, and tradition. 'The most dangerous thought that you can have as a creative person is to think that you know what you're doing,' explains Victor. 'Because once you think you know what you're doing you stop looking around for other ways of doing things and you stop being able to see other ways of doing things. You become blind.' He concludes, 'I think you have to say: "We don't know what programming is. We don't know what computing is. We don't even know what a computer is." And once you truly understand that, and once you truly believe that, then you're free, and you can think anything.'"

How To Build a Simple Open Source Server Monitoring Solution With Mobile Support 58

reifman writes "Nothing sucks more than finding an 'Error establishing database connection' on your blog hours after the fact, but it's not easy to find inexpensive, simple monitoring solutions which support smartphone notifications. I wrote MonitorApp, a free, open source software applet which sends notifications to your iPhone (or Android) if anything goes wrong with your web site or services. This tutorial describes how to install and configure MonitorApp for your own purposes. The only cost is a $4.99 mobile application called Pushover — which links MonitorApp to your phone. Pushover also links with Nagios, a more complex open source option — but ironically, Nagios' website was down when I looked for it last month."

NVIDIA Open Sources SHIELD's Operating System 83

hypnosec writes "NVidia has now open-sourced the operating system that powers the gaming console to encourage its modification and further development. Powered by NVidia's homegrown Tegra 4 processor, the console runs Android, which shouldn't surprise many as the company moves ahead with its open-sourcing intentions. The GPU company has said that the SHIELD is an 'open gaming platform' that allows for 'an open ecosystem,' enabling developers to develop content as well as applications that takes advantage of the underlying hardware and which can be enjoyed on bigger displays as well as mobile screen." Playing with it isn't without risks (like potentially voiding the warranty), but NVIDIA's blog post says they're also providing a recovery image to fall back to.
