Ask Slashdot: Swift Or Objective-C As New iOS Developer's 1st Language? 312

Posted by timothy
from the two-roads-diverge-but-do-they-loop dept.
macs4all (973270) writes "I am an experienced C and Assembler Embedded Developer who is contemplating for the first time beginning an iOS App Project. Although I am well-versed in C, I have thus-far avoided C++, C# and Java, and have only briefly dabbled in Obj-C. Now that there are two possibilities for doing iOS Development, which would you suggest that I learn, at least at first? And is Swift even far-enough along to use as the basis for an entire app's development? My goal is the fastest and easiest way to market for this project; not to start a career as a mobile developer. Another thing that might influence the decision: If/when I decide to port my iOS App to Android (and/or Windows Phone), would either of the above be an easier port; or are, for example, Dalvick and the Android APIs different enough from Swift/Obj-C and CocoaTouch that any 'port' is essentially a re-write?"

Rosetta Code Study Weighs In On the Programming Language Debate 165

Posted by Soulskill
from the fresh-ammunition dept.
An anonymous reader writes: Rosetta Code is a popular resource for programming language enthusiasts to learn from each other, thanks to its vast collection of idiomatic solutions to clearly defined tasks in many different programming languages. The Rosetta Code wiki is now linking to a new study that compares programming language features based on the programs available in Rosetta Code. The study targets the languages C, C#, F#, Go, Haskell, Java, Python, and Ruby on features such as succinctness and performance. It reveals, among other things, that: "functional and scripting languages are more concise than procedural and object-oriented languages; C is hard to beat when it comes to raw speed on large inputs, but performance differences over inputs of moderate size are less pronounced; compiled strongly-typed languages, where more defects can be caught at compile time, are less prone to runtime failures than interpreted or weakly-typed languages."

from the next-generation dept.
First time accepted submitter Molly McHugh writes Flickr Vice President Bernardo Hernandez explains how the beloved photo platform is targeting a new generation that's addicted to smartphones. “10 or 15 years ago it was expensive and complicated to explore the world of photography,” Hernandez said. "Very few people could afford that—[it is] no surprise the best photographers 20 years ago were older people. We believe all of that is changing with the mobile [photography] revolution."

An anonymous reader writes If you use Twitch don't click on any suspicious links in the video streaming platform's chat feature. Twitch Support's official Twitter account issued a security warning telling users not to click the "csgoprize" link in chat. According to f-secure, the link leads to a Java program that asks for your name and email. If you provide the info it will install a file on your computer that's able to take out any money you have in your Steam wallet, as well as sell or trade items in your inventory. "This malware, which we call Eskimo, is able to wipe your Steam wallet, armory, and inventory dry," says F-Secure. "It even dumps your items for a discount in the Steam Community Market. Previous variants were selling items with a 12 percent discount, but a recent sample showed that they changed it to 35 percent discount. Perhaps to be able to sell the items faster."

from the escallatio-isn't-just-for-lbj dept.
rfernand79 writes Infoworld has an interview with Martin Odersky, designer of Scala, in which they discuss the future of this popular language. Three versions are discussed as being part of the Scala roadmap: The first one (2.12) focuses on better integration with Java 8, and making use of the latest improvements in the JVM. The second one (Aida) focuses on cleaning up the Scala libraries. But the third one (Don Giovani) is about a fundamental rethink of Scala, with a strong focus on simplicity.

DMCA Claim Over GPL Non-Compliance Shuts Off Minecraft Plug-Ins 354

Posted by timothy
from the granting-license dept.
New submitter Maxo-Texas writes One of the primary programmers, Wesley Wolfe (Wolvereness), who contributed over 23,000 lines of code to the Bukkit project (which enhances Minecraft server performance and allows others to write mods and plugins) submitted a DMCA request September 5th, preventing use of his code in the popular Bukkit or Spigot (and numerous other Minecraft plugins, mods, and other open source enhancements that depend on them). This has the effect of freezing all further development for multi-player server Minecraft based on these add-ons until the issue is resolved.

The programmer says that Mojang must release the Minecraft server code to the public domain since decompiled, deobfuscated versions of the Java code are included in the Bukkit project before he will withdraw the DMCA. Mojang has never released the real source code and has stated they will not open source the server code to meet the GPL and LGPL licensing requirements. This approach might be a risk for other GPL and LGPL projects out there which are derivative of or enhance non GPL programs or products.
Mojang COO Vu Bui writes in a post at the Bukkit forums The official Minecraft Server software that we have made available is not included in CraftBukkit. Therefore there is no obligation for us to provide the original code or any source code to the Minecraft Server, nor any obligation to authorize its use. Our refusal to make available or authorize the use of the original / source code of the Minecraft Server software cannot therefore be considered to give rise to an infringement of any copyright of Wesley, nor any other person. Wesley’s allegations are therefore wholly unfounded.

Carmack On Mobile VR Development 60

Posted by Soulskill
from the duct-taping-a-phone-to-your-eyeballs dept.
An anonymous reader writes: After surprising everyone by demonstrating Samsung's new VR headset at IFA yesterday, John Carmack spoke with Gamasutra about the difficulties of developing virtual reality in a mobile environment. He also had some interesting comments on developing for Android: 'Okay, there's the normal hell of moving to a new platform — and I gotta say, Android was more hell to move to than most consoles I've adopted. Just because of the way Google has to position things across a diverse hardware spectrum, and because Google still doesn't really endorse native code development — they'd still rather everyone worked in Java. And that's a defensible position, but it's certainly not what you want to be doing on a resource-constrained VR system. So brace yourself: Android setup and development really does suck. It's no fun at all.' He also had insights on building compute-intensive software — if you go to full speed on all CPU and GPU cores, you can expect overheating and thermal throttling in less than a minute.

If Java Wasn't Cool 10 Years Ago, What About Now? 511

Posted by timothy
from the pretty-good-drink-especially-with-honey-and-cream dept.
10 years ago today on this site, readers answered the question "Why is Java considered un-cool?" 10 years later, Java might not be hip, but it's certainly stuck around. (For slightly more than 10 years, it's been the basis of the Advanced Placement test for computer science, too, which means that lots of American students are exposed to Java as their first formally taught language.) And for most of that time, it's been (almost entirely) Free, open source software, despite some grumbling from Oracle. How do you see Java in 2014? Are the pessimists right?

Russia Cracks Down On Public Wi-Fi; Oracle Blocks Java Downloads In Russia 254

Posted by timothy
from the interesting-times dept.
Linking to a story at Reuters, reader WilliamGeorge writes "Russia is further constraining access to the internet and freedom of speech, with new laws regarding public use of WiFi. Nikolai Nikiforov, the Russian Communications Minister, tweeted that "Identification of users (via bank cards, cell phone numbers, etc.) with access to public Wifi is a worldwide practice." This comes on top of their actions recently to block websites of political opponents to Russian president Vladimir Putin, require registration of prominent bloggers, and more. The law was put into effect with little notice and without the input of Russian internet providers. Sergei Plugotarenko, head of the Russian Electronic Communications Association, said "It was unexpected, signed in such a short time and without consulting us." He added, "We will hope that this restrictive tendency stops at some point because soon won't there be anything left to ban." In addition to the ID requirement to use WiFi, the new law also requires companies to declare who is using their web networks and calls for Russian websites to store their data on servers located in Russia starting in 2016." That's not the only crackdown in progress, though: former Slashdot code-wrestler Vlad Kulchitski notes that Russian users are being blocked from downloading Java with an error message that reads, in essence, "You are in a country on which there is embargo; you cannot download JAVA." Readers at Hacker News note the same, though comments there indicate that the block may rely on a " specific and narrow IP-block," rather than being widespread. If you're reading this from Russia, what do you find?

Oracle Hasn't Killed Java -- But There's Still Time 371

Posted by Unknown Lamer
from the common-lisp-rising dept.
snydeq (1272828) writes Java core has stagnated, Java EE is dead, and Spring is over, but the JVM marches on. C'mon Oracle, where are the big ideas? asks Andrew C. Oliver. 'I don't think Oracle knows how to create markets. It knows how to destroy them and create a product out of them, but it somehow failed to do that with Java. I think Java will have a long, long tail, but the days are numbered for it being anything more than a runtime and a language with a huge install base. I don't see Oracle stepping up to the plate to offer the kind of leadership that is needed. It just isn't who Oracle is. Instead, Oracle will sue some more people, do some more shortsighted and self-defeating things, then quietly fade into runtime maintainer before IBM, Red Hat, et al. pick up the slack independently. That's started to happen anyhow.'

Ask Slashdot: Best PDF Handling Library? 132

Posted by timothy
from the when-vi-is-not-the-answer dept.
New submitter Fotis Georgatos (3006465) writes I recently engaged in a conversation about handling PDF texts for a range of needs, such as creation, manipulation, merging, text extraction and searching, digital signing etc etc. A couple of potential picks popped up (PDFBox, itext), given some Java experience of the other fellows. And then comes the reality of choosing software as a long term knowledge investment! ideally, we would like to combine these features:
  • open source, with a community following ; the kind of stuff Slashdotters would prefer
  • tidy software architecture; simple things should remain simple
  • allow open API allowing usage across many languages (say: Python & Java)
  • clear licensing status, not estranging future commercial use
  • serious multilingual & font support
  • PDF-handling rich features, not limiting usage for invoicing, e-commerce, reports & data mining
  • digital signing should not go against other features

I'd like to poll the collective Slashdot crowd wisdom about if/which PDF related libraries, they have written software with, keeps them happy for *all* the above reasons. And if not happy with that all, what do they thing is the best bet for learning one piece of software in the area, with great reusability across different circumstances and little need for extra hacks? I'd really like to hear the smoked out war stories. It is easy to obtain a list of such libraries, yet tricky to understand whethe people have obtained success with them!

Ask Slashdot: "Real" Computer Scientists vs. Modern Curriculum? 637

An anonymous reader writes At work yesterday, I overheard a programmer explaining his perception of the quality of the most recent CS grads. In his opinion, CS students who primarily learn Java are inferior because they don't have to deal with memory management as they would if they used C. As a current CS student who's pursing a degree after 10 years of experience in the IT field, I have two questions for my fellow Slashdoters: "Is this a common concern with new CS grads?" and, if so, "What can I do to supplement my Java-oriented studies?"

Old Apache Code At Root of Android FakeID Mess 127

Posted by Soulskill
from the write-once-run-anywhere dept.
chicksdaddy writes: A four-year-old vulnerability in an open source component that is a critical part of Android leaves hundreds of millions of mobile devices susceptible to silent malware infections. The vulnerability affects devices running Android versions 2.1 to 4.4 ("KitKat"), according to a statement released by Bluebox. The vulnerability was found in a package installer in affected versions of Android. The installer doesn't attempt to determine the authenticity of certificate chains that are used to vouch for new digital identity certificates. In short, Bluebox writes, "an identity can claim to be issued by another identity, and the Android cryptographic code will not verify the claim."

The security implications of this are vast. Malicious actors could create a malicious mobile application with a digital identity certificate that claims to be issued by Adobe Systems. Once installed, vulnerable versions of Android will treat the application as if it was actually signed by Adobe and give it access to local resources, like the special webview plugin privilege, that can be used to sidestep security controls and virtual 'sandbox' environments that keep malicious programs from accessing sensitive data and other applications running on the Android device. The flaw appears to have been introduced to Android through an open source component, Apache Harmony. Google turned to Harmony as an alternative means of supporting Java in the absence of a deal with Oracle to license Java directly.

Work on Harmony was discontinued in November, 2011. However, Google has continued using native Android libraries that are based on Harmony code. The vulnerability concerning certificate validation in the package installer module persisted even as the two codebases diverged.

Famo.us: Do We Really Need Another JavaScript Framework? 104

Posted by Soulskill
from the let's-create-a-javascript-framework-to-find-out dept.
An anonymous reader writes Front-end developer Jaroen Janssen has a post about Famo.us, "a custom built JavaScript 3D rendering and physics engine meant as a replacement for the standard layout engine of the browser." The engine effectively replaces a big chunk of HTML5 in order to render more efficiently by using technology based on WebGL. Janssen questions whether the world really needs another JavaScript framework: "Is it a bad thing that Famo.us replaces major parts of HTML5? To be honest, I'm not sure. As a Front-end developer I have to admit it makes me slightly uneasy to have to use a custom API instead of 'standard' HTML5. On the other hand, like almost everyone that makes web apps for a living, I have been terribly frustrated by some of HTML5 limitations, like slowness and browser incompatibilities. Either way, it might be a good thing to try a fundamentally different approach so I'm keeping an open mind for now.

Famo.us chases another holy grail, namely the 'write once, run anywhere' dream. Instead of having to write different code for different platforms, like iOS and Android, developers can write one application that works and looks as good on all platforms, in theory anyway. This of course saves a huge amount of time and resources. Unfortunately, this idea is not without its problems and has never really worked very well with earlier attempts like Java-applets, Flash and Silverlight. In the end native applications have so far always been faster and slicker and I'm pretty skeptical Famo.us will be able to change this."

One small step for man, one giant stumble for mankind.
