Apple Doubles MacBook Pro R/W Performance 204

Lucas123 writes Benchmark tests performed on the 2015 MacBook Pro revealed it does have twice the read/write performance as the mid-2014 model. Tests performed with the Blackmagic benchmark tool revealed read/write speeds of more than 1,300MBps/1,400MBps, respectively. So what's changed? The new MacBook Pro does have a faster Intel dual-core i7 2.9GHz processor and 1866MHz LPDDR3) RAM, but the real performance gain is in the latest PCIe M.2 flash module. The 2014 model used a PCIe 2.0 x2 card and the 2015 model uses a PCIe 3.0 x4 (four I/O lanes) card. Twice the lanes, twice the speed. While Apple uses a proprietary flash card made by Samsung, Intel, Micron and SanDisk are all working on similar technology, so it's likely to soon wind up in high-end PCs.

Comment Re:I miss Google Search (Score 2) 150

They used to have a great search engine, but then they replaced it with something that keeps second-guessing my search terms.

Probably the most annoying part of this for me is the blazingly stupid way they'll just drop words from your query. There have been times when I submit a phrase with 4 or 5 search terms, and most of the first page is filled with results that have 3 or 4 of the words crossed out. The results were useless garbage and I'd rather have been told there were no pages found. Along with this is the absolutely horrible decision to remove the functionality of the (+) symbol to mean "required". I don't know what social media asshats at Google made this call, but I curse them every time I have to put double quotes around a bunch of individual words just so the aforementioned query "optimizer" doesn't screw with it.

I'm pretty sure that bad design on Google's part combined with the constant abuse of the system by "SEO specialists" has turned Google Search into something inferior to what we had 10 years ago. Oh, and don't forget the malicious adwords results serving up malware for popular software titles. That's always a winner.

Comment Re:Why uTorrent? (Score 1) 275

Why are you using any version above 2.2.1?

Came here to say exactly this.

After seeing what version 3 looked like on a friend's computer (code isn't the only thing that got bloated with crap) and reading about the hassle people were having with advertising, user-hostile admins, and finally seeing uTorrent get bought out, I'm glad I never bothered to update past 2.2.1. Some private trackers even block 3.x.

I've also heard good things about Deluge, so if I'm ever forced into updating I'll probably give that a try.

Pretty interesting concept and if it works as well in the real world as the video portrays, it could be very cool to use. I was all ready to sign up for early access and talk about it with my team on Monday, until I saw your comment below that it only works on Apple devices.

In the tech and development world (especially in the trenches) Android rules, and our office is no exception. What a downer.

He died at 83; smoking probably didn't kill him so much as being old.

Considering the cause of death was end-stage chronic obstructive pulmonary disease, I'd guess smoking played a major part. Says Wikipedia:

Tobacco smoking is the most common cause of COPD, with a number of other factors such as air pollution and genetics playing a smaller role.

But it's a sad day regardless.

As someone who was quite vocal against Beta in the original announcement article, I've got to say that this about-face is a pleasant surprise. I don't love everything about it, but it's a far sight better than what we saw on the beta site. Glad to see the powers that be came to their senses, and were not persuaded by UX blowhards.

One bug/design issue is with the comment margins. Here's what I'm seeing in Firefox: http://i.imgur.com/YPhBVI0.png

Playing with the CSS, I think this is easier on the eyes and feels a lot less squished: http://i.imgur.com/npol1Kq.png

Which I got with this:

    #commentwrap, #commentlisting {

    #commentlisting {

Now how about some proper Unicode support? :)

Video Female-Run Companies Often do Better Than Male-Run Ones (Video) 271

Today's interviewee, Viktoria Tsukanov, is one of the executives at predictive marketing company Mintigo who did a study in January, 2015 that seemed to show that large companies with female CEOs "achieve up to 18% higher revenue per employee than male CEOs." The study, titled "She’s the CEO and She’s Sensational," used financial data Mintigo collected on 20 million companies, and determined CEOs' genders by analyzing first names, so it was not subject to survey vagaries but was a straight data analysis job. Could this be a case of correlation and causation being unrelated? It's possible. It's also possible that the revenue per employee figures are affected by the fact that female CEOs are more common in healthcare and non-profit organizations, while men dominate manufacturing and construction -- and, as Viktoria pointed out in a blog post headlined "Women Just Raised the Bar. Big Time." there may be other factors at work as well.

The "18% higher revenue" figure specifically applies to companies with more than 1000 workers, while companies with fewer workers may average more revenue per employee if they have male CEOs. Besides discussing the study itself, in our interview Viktoria talks about how male employees might want to alter (or not alter) their behavior if they find themselves working for a female boss for the first time. She also discusses challenges a woman might face if she is suddenly put in charge of a heavily male IT or programming staff. Other thoughts she shares have to do with finding mentors and dealing with negative people, both of which apply to people of all genders. Interesting food for thought all around.

Video Listnr Wants to be 'Your Listening Assistant' (Video) 45

This Listnr is "a new listening device connected to the cloud" being developed by a team in Japan that's currently running a Kickstarter project looking for $50,000 by March 7. The other Listnr "is a free music service helping people discover the best music from independent artists on Soundcloud and Bandcamp." More accurately, that's what it was, since their last Facebook post was in 2011 and their domain name is now for sale. Today's Listnr -- the listening device one -- claims it is able to tell whether a baby it hears is laughing, crying, gurgling or trying to talk. It is supposed to respond to finger snaps, hand claps, and other audio commands. It has an open API so that you can extend its use however you like. The company, too, is working on new applications for their product. Will there be enough of them, and will they interest enough people, to make this a success? Co-Founder Rie Ehara says, "We wanted to build something using sound to enrich and delight our lives." As of today (Feb. 2), Listnr is slightly less than halfway to its Kickstarter goal, so it's still a coin-toss whether or not Listnr will succeed.

Senator Who Calls STEM Shortage a Hoax Appointed To Head Immigration 514

dcblogs (1096431) writes The Senate's two top Republican critics of temporary worker immigration, specifically the H-1B and L-1 visas, now hold the two most important immigration posts in the Senate. They are Sen. Chuck Grassley (R-Iowa), who heads the Senate's Judiciary Committee, and his committee underling, Jeff Sessions (R-Ala.), who was appointed by Grassley on Thursday to head the immigration subcommittee. Sessions was appointed one week after accusing the tech industry of perpetuating a "hoax" by claiming there is a shortage of qualified U.S. tech workers. "The tech industry's promotion of expanded temporary visas — such as the H-1B — and green cards is driven by its desire for cheap, young and immobile labor," wrote Sessions, in a memo he sent last week to fellow lawmakers. Sessions, late Thursday, issued a statement about his new role as immigration subcommittee chairman, and said the committee "will give voice to those whose voice has been shut out," and that includes "the voice of the American IT workers who are being replaced with guest workers."

New Advance Confines GMOs To the Lab Instead of Living In the Wild 130

BarbaraHudson (3785311) writes In Jurassic Park, scientists tweak dinosaur DNA so that the dinosaurs were lysine-deficient in order to keep them from spreading in the wild. Scientists have taken this one step further as a way to keep genetically modified E. coli from surviving outside the lab. In modifying the bacteria's DNA to thwart escape, two teams altered the genetic code to require amino acids not found in nature. One team modified the genes that coded for proteins crucial to cell functions so that that produced proteins required the presence of the synthetic amino acid in the protein itself. The other team focused on 22 genes deemed essential to a bacterial cell's functions and tied the genes' expression to the presence of synthetic amino acids. For the bacteria to survive, these synthetic amino acids had to be present in the medium on which the bacteria fed. In both cases, the number of escapees was so small as to be undetectable."

Gender and Tenure Diversity In GitHub Teams Relate To Higher Productivity 106

New submitter Bogdan Vasilescu writes: Diversity in teams is a double-edged sword. Increased team diversity results in more varied backgrounds and ideas, providing the team with access to broader information, enhanced creativity, adaptability, and problem solving skills. However, due to greater perceived differences in values, norms, and communication styles in more diverse teams, members become more likely to engage in stereotyping, cliquishness, and conflict.

In a recent study, researchers from University of California, Davis and Eindhoven University of Technology, The Netherlands have analyzed the effects of gender and tenure diversity on productivity and turnover for more than 23,000 open-source projects on GitHub. Using regression modeling, they showed that after controlling for team size and other confounds (such as a project's age, development model, or amount of social activity), both gender and tenure diversity are positive and significant predictors of productivity, together explaining a small but significant fraction of the data variability. On an economic and societal scale, these findings suggest that added investments in educational and professional training efforts and outreach for female programmers will likely result in added overall value.

The paper describing the results (preprint PDF here) will be presented at the prestigious ACM CHI Conference on Human Factors in Computing Systems, in Seoul, South Korea, in April 2015.

Doxing Victim Zoe Quinn Launches Online "Anti-harassment Task Force" 693

AmiMoJo writes: On Friday, developer and doxing victim Zoe Quinn launched an online "anti-harassment task force" toolset, staffed by volunteers familiar with such attacks, to assist victims of a recent swell of "doxing" and "swatting" attacks. The Crash Override site, built by Quinn and game developer Alex Lifschitz, offers free services from "experts in information security, white hat hacking, PR, law enforcement, legal, threat monitoring, and counseling" for "victims of online mob harassment."

They have already managed to preemptively warn at least one victim of a swatting attempt in Enumclaw, Washington. As a result, the police department's head e-mailed the entire department to ask any police sent to the address in question to "knock with your hand, not your boot."
