Comment The future is in the past! (Score 5, Interesting) 206

Take a look at Squeak ( ). As it turns out most things in the future will have their roots in the discarded ideas of the past. As far as programming languages take a look at Erlang and Elixir (computer languages are the operating systems of the future). I expect the capability model and the actor model will get a lot more popular in the future. In the future computers will be networks, applications will be distributed applications.

Comment Definitely Elixir (Score 1) 429

Elixir is a functional, concurrent, general-purpose programming language that runs on the Erlang virtual machine (BEAM). Elixir builds on top of Erlang to provide distributed, fault-tolerant, soft real-time, non-stop applications but also extends it to support metaprogramming with macros and polymorphism via protocols.

Think of it as a mix of Ruby, Haskell and Erlang without too many compromises.

Comment USB to IDE or Trumpet Winsock (Score 2) 466

You best bet is to get the drive hooked up to a USB to IDE adapter and copy the files.

If that doesn't work get and USB to RS232 cable and a NULL Modem Adapter and connect your two machines. Ideally you should setup Linux with pppd on the new computer. Run Trumpet Winsock on your old laptop and do a manual login and just hit ESC as soon as the terminal window shows up. Once that works install and ftp daemon on one of the two machines and a ftp client on the other side. Then just copy your files.

Comment Re:Population is not a real issue here (Score 1) 625

I noticed that everyone quickly jumped to the population problem. In fact this is not an issue at all.

Everything that grows exponentially has a doubling rate. One could easily argue that the real problem is in the newer generations since they will always represent significantly bigger population than the previous one. So the issue is not people not dying quickly, the problem is people being born. If everyone stopped having kids and would magically become biologically immortal the growth rate would be negative or 0% (due to the fact that people die in accidents).

Oh and by the way the only sustainable growth rate is exactly 0% not more. Anything more would mean it has a doubling rate. It's basic math.

It's true that population is not a big issue. But I am afraid the corrupt would use it to maintain their status indefinitely.

Submission + - Java concurrency is orders of magnitude harder than people think (

An anonymous reader writes: A user on StackOverflow claims to have lost $12 million of equipment due to a seemingly obscure behavior with concurrency in Java. A commenter on Hacker News writes

How can anyone program sanely in the presence of this: currentPos = new Point(currentPos.x+1, currentPos.y+1); does a few things, including writing default values to x and y (0) and then writing their initial values in the constructor. Since your object is not safely published those 4 write operations can be freely reordered by the compiler / JVM. [...] I'm not anywhere near smart or careful enough for that... I think I'll stick with Haskell.

Submission + - Syrian Electronic Army has proven one thing about the cybersecurity community

Jeff Peters writes: From an editorial at HackSurfer describing the problem with cybersecurity that has emerged following the SEA hacks:

The state of the cybersecurity profession today, as well as the software industry it drives, is best described by using a religion analogy. Our business leaders are dependent on a largely crowded, confused, splintered, factious, self-righteous community of “holier than thou” experts and engineers convinced of the supremacy of their 10 billion differing points of view. If you've worked in the information technology industry as I have for 20 years (recovering software engineer), you may not admit it openly, but you know exactly what I’m talking about. One of my closest friends, a name most of you would recognize in the IT industry, once described most system administrators by saying:

“They’re either completely terrible or they’re self-righteous dicks. I always choose the dicks because at least I’ll be a little safer.”

Kinda captures it for me. “Sharing” and “plays well with others” not anywhere in the definition. I won’t even repeat his sentiments on most CISSPs.

Submission + - Media Campaign Against Snowden? (

sl4shd0rk writes: With Snowden living somewhere in Russia, and the US having very little course of action in way of damage control, it would seem the best US option would be to attack Snowden's credibility. Perhaps muddy the waters with something germane to System administration, yet somehow easily construed into a criminal act. According to Reuters, Snowden "began downloading documents" related to illegal US spying programs perhaps as early as April of 2012. Of course, the sources of this claim are "U.S. officials and other sources familiar with the matter" which roughly narrows it down from Gen. Michael Hayden to just about anyone who blogged on it. Fact of the matter is, without more details, Snowden could have accessed documents simply by performing backup routines or investigating file system issues. Things which happen quite regularly during the daily course of system adminstration. Without more specificity on the method in question, one is left with an impression from the headline, one of a nefarious circumstance.

Submission + - FISC Secret Court Chief Judge: We can't effectively oversee the NSA ( 1

An anonymous reader writes: Via the Washington Post: "The leader of the secret court that is supposed to provide critical oversight of the government’s vast spying programs said that its ability to do so is limited and that it must trust the government to report when it improperly spies on Americans. The chief judge of the Foreign Intelligence Surveillance Court said the court lacks the tools to independently verify how often the government’s surveillance breaks the court’s rules that aim to protect Americans’ privacy. Without taking drastic steps, it also cannot check the veracity of the government’s assertions that the violations its staff members report are unintentional mistakes."

President Obama: "We also have federal judges that we’ve put in place who are not subject to political pressure,” Obama said at a news conference in June. “They’ve got lifetime tenure as federal judges, and they’re empowered to look over our shoulder at the executive branch to make sure that these programs aren’t being abused.”

Not so much, Mr. President.

Submission + - Carbyne: A Form of Carbon Even Stronger Than Graphene 1

Dialecticus writes: Sebastian Anthony at ExtremeTech has written an article about research into the physical properties of carbyne, an elusive form of carbon. A new mathematical analysis by Mingjie Liu and others at Rice University suggests that carbyne may achieve double the strength of graphene, stealing its crown and becoming the strongest material known to man.

Submission + - Incredible Footage Shows a Perseid Meteor Exploding (

Nancy_A writes: Photographer and digital artist Michael K. Chung said he couldn’t believe what he saw when he was processing images he took for a timelapse of the Perseid meteor shower this week. It appears he captured a meteor explosion and the resulting expansion of a shock wave or debris ring.

After this article was posted, Universe Today received more 'explody' footage from the Perseid meteor shower, which has been added to the article.

Submission + - Ubuntu Edge Now Most-Backed Crowdfunding Campaign Ever

Volanin writes: After nearly a month of its assumed happening, Ubuntu Edge has now passed the $10.2 million mark, thus making it the most pledged-to crowd-funder in history. While the Ubuntu Edge campaign is to be commended for reaching such a mammoth milestone as this, it can’t quite claim ultimate victory yet, since it's just short of making one-third of its $32 million goal with a little less than a week left. Can they do it?
