Ask Slashdot: What's the Best Working Environment For a Developer?

2017-03-28T00:10:00+00:00

New submitter Dorgendubal writes: I work for a company with more than a thousand developers and I'm participating in activities aimed at improving the work experience of developers. Our developers receive an ultrabook that is rather powerful but not really adapted for development (no admin rights, small storage capacity, restrictive security rules, etc.). They also have access to VDIs (more flexibility) but often complain of performance issues during certain hours of the day. Overall, developers want to have maximum autonomy, free choice of their tools (OS, IDE, etc.) and access to internal development environments (PaaS, GIT repositories, continuous delivery tools, etc.) . We recently had a presentation of VMWare on desktop and application virtualization (Workstation & Horizon), which is supposedly the future of the desktops. It sounds interesting on paper but I remain skeptical. What is the best working environment for a developer, offering flexibility, performance and some level of free choice, without compromising security, compliance, licensing (etc.) requirements? I would like you to share your experiences on BYOD, desktop virtualization, etc. and the level of satisfaction of the developers.

Facial Recognition Database Used By FBI Is Out of Control, House Committee Hears

2017-03-27T23:30:00+00:00

The House oversight committee claims the FBI's facial recognition database is out of control, noting that "no federal law controls this technology" and "no court decision limits it." At last week's House oversight committee hearing, politicians and privacy campaigners presented several "damning facts" about the databases. "About 80% of photos in the FBI's network are non-criminal entries, including pictures from driver's licenses and passports," reports The Guardian. "The algorithms used to identify matches are inaccurate about 15% of the time, and are most likely to misidentify black people than white people." From the report: "Facial recognition technology is a powerful tool law enforcement can use to protect people, their property, our borders, and our nation," said the committee chair, Jason Chaffetz, adding that in the private sector it can be used to protect financial transactions and prevent fraud or identity theft. "But it can also be used by bad actors to harass or stalk individuals. It can be used in a way that chills free speech and free association by targeting people attending certain political meetings, protests, churches, or other types of places in the public." Furthermore, the rise of real-time face recognition technology that allows surveillance and body cameras to scan the faces of people walking down the street was, according to Chaffetz, "most concerning." "For those reasons and others, we must conduct proper oversight of this emerging technology," he said.

Prominent Drupal, PHP Developer Kicked From the Drupal Project Over Unconventional Sex Life

2017-03-27T22:50:00+00:00

An anonymous Slashdot reader writes: Last week the Drupal community erupted in anger after its leader, Dries Buytaert, asked Larry Garfield, a prominent Drupal contributor and long-time member of the Drupal and PHP communities, "to leave the Drupal project." Buytaert claims he did this "because it came to my attention that he holds views that are in opposition with the values of the Drupal project." A huge furor has erupted in response -- not least because the reason clearly has much to do with Garfield's unconventional sex life. [Garfield is into BDSM, and is a member of the Gorean community, "a community who are interested in, and/or participate in, elaborate sexual subjugation fantasies, in which men are inherently superior to women."] Buytaert made his post (which is now offline) in response after Larry went public, outing himself to public opinion. Buytaert retorted (excerpt available via TechCrunch): "when a highly-visible community member's private views become public, controversial, and disruptive for the project, I must consider the impact [...] all people are created equally. [sic] I cannot in good faith support someone who actively promotes a philosophy that is contrary to this [...] any association with Larry's belief system is inconsistent with our project's goals [...] I recused myself from the Drupal Association's decision [to dismiss Garfield from his conference role] [...] Many have rightfully stated that I haven't made a clear case for the decision [...] I did not make the decision based on the information or beliefs conveyed in Larry's blog post." TechCrunch columnist Jon Evans goes on to "unpack" the questions that naturally arise from these "Code of Conduct conflicts."

After 20 Years, OpenSSL Will Change To Apache License 2.0, Seeks Past Contributors

2017-03-26T22:59:00+00:00

After nearly 20 years and 31,000 commits, OpenSSL wants to change to Apache License v2.0. They're now tracking down all 400 contributors to sign new license agreements, a process expected to take several months. Slashdot reader rich_salz shares links to OpenSSL's official announcement (and their agreement-collecting web site). "This re-licensing activity will make OpenSSL, already the world's most widely-used FOSS encryption software, more convenient to incorporate in the widest possible range of free and open source software," said Mishi Choudhary, Legal Director of Software Freedom Law Center and counsel to OpenSSL. "OpenSSL's team has carefully prepared for this re-licensing, and their process will be an outstanding example of 'how to do it right.'" Click through for some comments on the significance of this move from the Linux Foundation, Intel, and Oracle.

Apache Hadoop Has Failed Us, Tech Experts Say

2017-03-25T21:34:00+00:00

It was the first widely-adopted open source distributed computing platform. But some geeks running it are telling Datanami that Hadoop "is great if you're a data scientist who knows how to code in MapReduce or Pig...but as you go higher up the stack, the abstraction layers have mostly failed to deliver on the promise of enabling business analysts to get at the data." Slashdot reader atcclears shares their report: "I can't find a happy Hadoop customer. It's sort of as simple as that," says Bob Muglia, CEO of Snowflake Computing, which develops and runs a cloud-based relational data warehouse offering. "It's very clear to me, technologically, that it's not the technology base the world will be built on going forward"... [T]hanks to better mousetraps like S3 (for storage) and Spark (for processing), Hadoop will be relegated to niche and legacy statuses going forward, Muglia says. "The number of customers who have actually successfully tamed Hadoop is probably less than 20 and it might be less than 10..." One of the companies that supposedly tamed Hadoop is Facebook...but according to Bobby Johnson, who helped run Facebook's Hadoop cluster before co-founding behavioral analytics company Interana, the fact that Hadoop is still around is a "historical glitch. That may be a little strong," Johnson says. "But there's a bunch of things that people have been trying to do with it for a long time that it's just not well suited for." Hadoop's strengths lie in serving as a cheap storage repository and for processing ETL batch workloads, Johnson says. But it's ill-suited for running interactive, user-facing applications... "After years of banging our heads against it at Facebook, it was never great at it," he says. "It's really hard to dig into and actually get real answers from... You really have to understand how this thing works to get what you want." Johnson recommends Apache Kafka instead for big data applications, arguing "there's a pipe of data and anything that wants to do something useful with it can tap into that thing. That feels like a better unifying principal..." And the creator of Kafka -- who ran Hadoop clusters at LinkedIn -- calls Hadoop "just a very complicated stack to build on."

Stack Overflow Reveals Results From 'Largest Developer Survey Ever Conducted'

2017-03-25T15:34:00+00:00

More than 64,000 developers from 213 countries participated in this year's annual survey by Stack Overflow -- the largest number ever -- giving a glimpse into the collective psyche of programmers around the world. An anonymous reader quotes their announcement: A majority of developers -- 56.5% -- said they were underpaid. Developers who work in government and non-profits feel the most underpaid, while those who work in finance feel the most overpaid... While only 13.1% of developers are actively looking for a job, 75.2% of developers are interested in hearing about new job opportunities... When asked what they valued most when considering a new job, 53.3% of respondents said remote options were a top priority. 65% of developers reported working remotely at least one day a month, and 11.1% say they're full-time remote or almost all the time. Also, the highest job satisfaction ratings came from developers who work remotely full-time. 62.5% of the respondents reported using JavaScript, while 51.2% reported SQL, with 39.7% using Java and 34.1% using C# -- but for the #5 slot, "the use of Python [32.0%] overtook PHP [28.1%] for the first time in five years." Yet as far as which languages developers wanted to continue using, "For the second year in a row, Rust was the most loved programming language... Swift, last year's second most popular language, ranked as fourth. For the second year in a row, Visual Basic (for 2017, Visual Basic 6, specifically) ranked as the most dreaded language; 88.3% of developers currently using Visual Basic said they did not want to continue using it."

Blinking Cursor Devours CPU Cycles in Visual Studio Code Editor

2017-03-24T18:01:00+00:00

An anonymous reader shares a report on The Register: Microsoft describes Visual Studio Code as a source code editor that's "optimized for building and debugging modern web and cloud applications." In fact, VSC turns out to be rather inefficient when it comes to CPU resources. Developer Jo Liss has found that the software, when in focus and idle, uses 13 percent of CPU capacity just to render its blinking cursor. Liss explains that the issue can be reproduced by closing all VSC windows, opening a new window, opening a new tab with an empty untitled file, then checking CPU activity. For other macOS applications that present a blinking cursor, like Chrome or TextEdit, Liss said, the CPU usage isn't nearly as excessive. The issue is a consequence of rendering the cursor every 16.67ms (60 fps) rather than every 500ms.

LastPass Bugs Allow Malicious Websites To Steal Passwords

2017-03-23T00:45:00+00:00

Earlier this month, a Slashdot reader asked fellow Slashdotters what they recommended regarding the use of password managers. In their post, they voiced their uncertainty with password managers as they have been hacked in the past, citing an incident in early 2016 where LastPass was hacked due to a bug that allowed users to extract passwords stored in the autofill feature. Flash forward to present time and we now have news that three separate bugs "would have allowed a third-party to extract passwords from users visiting a malicious website." An anonymous Slashdot reader writes via BleepingComputer: LastPass patched three bugs that affected the Chrome and Firefox browser extensions, which if exploited, would have allowed a third-party to extract passwords from users visiting a malicious website. All bugs were reported by Google security researcher Tavis Ormandy, and all allowed the theft of user credentials, one bug affecting the LastPass Chrome extension, while two impacted the LastPass Firefox extension [1, 2]. The exploitation vector was malicious JavaScript code that could be very well hidden in any online website, owned by the attacker or via a compromised legitimate site.

Performance Bugs, 'the Dark Matter of Programming Bugs', Are Out There Lurking and Unseen

2017-03-22T16:00:00+00:00

Several Slashdot readers have shared an article by programmer Nicholas Chapman, who talks about a class of bugs that he calls "performance bugs". From the article: A performance bug is when the code computes the correct result, but runs slower than it should due to a programming mistake. The nefarious thing about performance bugs is that the user may never know they are there -- the program appears to work correctly, carrying out the correct operations, showing the right thing on the screen or printing the right text. It just does it a bit more slowly than it should have. It takes an experienced programmer, with a reasonably accurate mental model of the problem and the correct solution, to know how fast the operation should have been performed, and hence if the program is running slower than it should be. I started documenting a few of the performance bugs I came across a few months ago, for example (on some platforms) the insert method of std::map is roughly 7 times slower than it should be, std::map::count() is about twice as slow as it should be, std::map::find() is 15% slower than it should be, aligned malloc is a lot slower than it should be in VS2015.

Android O First Developer Preview Featuring Notification Channels, Background Limits Now Available

2017-03-21T18:43:00+00:00

A year after Google released the Android N Developer Preview, the company has made available the developer preview of the next major version of Android, "Android O." You will not want to put it on your primary Android smartphone as the preview is likely to have rough edges. Google says as much. "it's early days, there are more features coming, and there's still plenty of stabilization and performance work ahead of us. But it's booting :)." The company is using the developer preview to give beta testers a sneak peek into some new features, such as "notification channels," which will offer users the ability to group notifications. There is also Picture in Picture, which will enable you to have a video appear in a small window on top of homescreen or any application. Google is also adding "multi-display support" and improved "keyboard navigation." Your guess is as good as mine as to what these features will actually do. There's also better "background limits" which will supposedly help save battery, and wider Wi-Fi support to include things like Neighborhood Aware Networking (NAN). No word on what "O" in Android O stands for.

GitHub Now Lets Its Workers Keep the IP When They Use Company Resources For Personal Projects

2017-03-21T15:20:00+00:00

If it's on company time, it's the company's dime. That's the usual rule in the tech industry -- that if employees use company resources to work on projects unrelated to their jobs, their employer can claim ownership of any intellectual property (IP) they create. But GitHub is throwing that out the window. From a report on Quartz: Today the code-sharing platform announced a new policy, the Balanced Employee IP Agreement (BEIPA). This allows its employees to use company equipment to work on personal projects in their free time, which can occur during work hours, without fear of being sued for the IP. As long as the work isn't related to GitHub's own "existing or prospective" products and services, the employee owns it. Like all things related to tech IP, employee agreements are a contentious issue. In some US states, it's not uncommon for contracts to give companies full ownership of all work employees produce during their tenure, and sometimes even before and after their tenure, regardless of when or how they produce it. These restrictions have led to several horror stories, like the case of Alcatel vs. Evan Brown.

O'Reilly Site Lists 165 Things Every Programmer Should Know

2017-03-19T23:46:00+00:00

97 Things Every Programmer Should Know was published seven years ago by O'Reilly Media, and was described as "pearls of wisdom for programmers collected from leading practitioners." Today an anonymous reader writes: All 97 are available online for free (and licensed under a Creative Commons Attribution 3), including an essay by "Uncle Bob" on taking personal responsibility and "Unix Tools Are Your Friend" by Athens-based professor Diomidis Spinellis, who writes that the Unix tool chest can be more useful than an IDE. But the book's official site is also still accepting new submissions, and now points to 68 additional "edited contributions" (plus another seven "contributions in progress"), including "Be Stupid and Lazy" by Swiss-based Java programmer Mario Fusco, and "Decouple That UI" by tech trainer George Brooke. "There is no overarching narrative," writes the site's editor Kevlin Henney (who also wrote the original book). "The collection is intended simply to contain multiple and varied perspectives on what it is that contributors to the project feel programmers should know...anything from code-focused advice to culture, from algorithm usage to agile thinking, from implementation know-how to professionalism, from style to substance..."

America's Most Affordable Cities For Tech Workers: Seattle, Austin, and Pittsburgh

2017-03-19T21:46:00+00:00

"Seattle tech workers who own their homes can expect to have about $2,000 more in disposable income each month than tech workers in the Bay Area," according to a new study from LinkedIn and Zillow. An anonymous reader writes: "For technology workers who rent, Seattle, Austin and Pittsburgh, Pennsylvania came out on top among the housing markets analyzed, with the Bay Area at #4..." the two companies reported. "Salaries for other industries don't hold up as well in the San Francisco area, though. Even highly-paid finance workers keep only about 32 percent of their incomes after paying for housing and taxes. In Charlotte or Chicago, they can pocket a median of 61 percent." The Bay Area's high housing prices are apparently offset by the high salaries paid there to tech workers, according to the study. Even so, both home owners and renters pay roughly half the median income for housing on the west coast, "while a rental in the middle of the country costs more like 25 percent of the median income." The report also identified the best cities for health workers -- Phoenix, Indianapolis, and Boston -- as well as for finance workers, who do best in Charlotte, Chicago and Dallas. The top 15 cities for tech workers also included those same cities except Chicago and Phoenix, while also including known tech hotspots like Denver, Atlanta, and Washington, D.C. But surprisingly the top 15 best cities for tech workers also included Detroit, Nashville, St. Paul (Minnesota) and Tampa, Florida.

RedMonk Identifies 2017's Most Popular Languages: JavaScript, Java, And Python

2017-03-19T04:34:00+00:00

Twice a year the tech analysts at RedMonk attempt to gauge adoption trends for programing languages based on data from both GitHub and Stack Overflow. Here's their top 10 list for 2017: JavaScript, Java, Python, and PHP, followed by a two-way tie between C# and C++, a two-way tie between Ruby and CSS, and then C at #9, and Objective-C at #10. But their GitHub data now counts the number of pull requests rather than the number of repositories. An anonymous reader quotes their report: Swift was a major beneficiary of the new GitHub process, jumping eight spots from 24 to 16 on our GitHub rankings. While the language appears to be entering something of a trough of disillusionment from a market perception standpoint, with major hype giving way to skepticism in many quarters, its statistical performance according to the observable metrics we track remains strong. Swift has reached a Top 15 ranking faster than any other language we have tracked since we've been performing these rankings. Its strong performance from a GitHub perspective suggests that the wider, multi-platform approach taken by the language is paying benefits... Of all of the top tier languages, none jumped more than TypeScript on our GitHub rankings, as the JavaScript superset moved up 17 points.... PowerShell moved from 36 within the GitHub rankings to 19 to match TypeScript's 17 point jump, and that was enough to nudge it into the Top 20 overall from its prior ranking of 25... One of the biggest overall gainers of any of the measured languages, Rust leaped from 47 on our board to 26 â" one spot behind Visual Basic. Swift and Scala and Shell all just missed out on the top 10, clustering in a three-way tie at the #11 spot.

Ask Slashdot: What Is Your Horrible IT Boss Story?

2017-03-17T13:00:00+00:00

snydeq writes: Good-bye, programming peers; hello, power to abuse at your whim, writes Bob Lewis in a send-up of an all-too-familiar situation: The engineering colleague who transforms into a greasy political manipulator upon promotion into management. "It's legendary: A CIO promotes his best developer into a management role, losing an excellent programmer and gaining a bad manager. The art of management isn't so much about assembling a dream team, helping others be successful, or solving technical problems. It's about aligning everything you do in service of the business -- the business of yourself.'" What tales do you have of colleagues who broke bad all the way to the top?
