+ - Why Your Sysadmin Hates You->

Submitted by jfruh
jfruh writes "We've learned many lessons in the fallout from Edward Snowden's whistleblowing and flight to Hong Kong, but here's an important one: Never piss off your sysadmin. Even if your organization isn't running a secret, civil-rights violating surveillance program, you're probably managing to annoy your admins in a number of more pedestrian ways that might still have blowback for you. Learn to stay on their good side by going along with their reasonable requests and being specific with your complaints."

+ - Examining Ford's "best mileage" algorithms->

Submitted by Esther Schindler
Esther Schindler writes "Ford is busy working on ways to deliver data to ease range anxiety and other concerns drivers have about relying on electric vehicles. But while all the attention on energy-efficient electric vehicles is cool, it masks some interesting algorithms:

"We can generate a lot of simulations varying the traffic conditions and the driving style and calculate the energy and get a distribution of energy consumption [said Erica Klampfl, technical leader, strategy & sustainability analytics, at Ford Research & Advanced Engineering]. That really helps us answer this question, 'Under different scenarios, how far can I go?'" ... For the second question, "Is there a smarter way to get from Point A to Point B?", Klampfl said Ford uses a "robust route optimization algorithm that determines the optimal routes under energy consumption uncertainty." She compared this to the short-distance or fastest-route alternatives spewed out by any of the navigator apps many of us use regularly today. "What we're doing is, based on energy consumption uncertainty, figuring out what is the most robust route that will get you there most of the time."

This short article takes a look at some of the data-management things that Ford's working on."

+ - Meet a Professional Genome Wrangler->

Submitted by Esther Schindler
Esther Schindler writes "Computers have played a part in the pursuit of science for most of their history. Humanity would not have made it to the moon without a myriad of computers controlling every aspect of the space flight, and computers are crucial in modern statistical analysis of data. But bioinformatics, and specifically genomics (the study of the human genome, and how it influences traits and diseases), are even more critically dependent on the use of computers, for a number of reasons. In Meet a Professional Genome Wrangler: Madeleine Ball Keeps DNA Straight at Harvard’s Personal Genome Project, James Turner interviews Ball to discover what's involved in the process — geeky details and all.

If one genome is big, 100,000 genomes is overwhelmingly huge, and it’s Dr. Madeleine Ball’s job to keep all the data happy. Ball oversees data collection and the public data portals for the PGP, as their Director of Biology. This can be as awesomely geeky as tweaking python scripts to analyze data, or as mundane as packaging blood samples so they can be sent off to be biobanked.

To me, the most interesting stuff is in regard to data formats that only sound like standards.

One of Ball’s largest challenges is the lack of uniformity in personal health records (PHRs). The PGP program participants (who currently number in the low thousands) are very active, uploading all sorts of personal data such as PHRs, X-Rays, and MRI scans. Unfortunately, getting all that information into a consistent format is daunting. “Everyone has their own way of doing a health record,” says Ball, “And they all say, ‘Oh, we have electronic health records,’ as if it solves everything. That’s kind of like saying, ‘We all have Word documents;’ it doesn’t mean they’re all using the same coding systems.”

See what you think."

+ - Supermarkets Are High-Tech Hotbeds->

Submitted by Esther Schindler
Esther Schindler writes "You don't think of your supermarket as the source of geeky innovation, but you may be surprised. For example, in Steven Cherry's Supermarkets Are High-Tech Hotbeds, a Techwise Conversation with Kurt Kendall, a partner and director at Kurt Salmon, where he heads the analytics practice there, we learn:

A lot of supermarket tech is at the checkout area. Bar-code scanning was already old hat when U.S. president George Bush the elder was allegedly amazed by them in 1992, and retailers continue to experiment with the next logical step: self-checkout systems.

Here's some of the ways you'll find spiffy stuff among the lettuce:

There’s a lot of technologies out there right now that are being introduced into the retail space to understand what consumers are doing in the store, and heat-mapping is one of those technologies--using cameras in the ceiling to actually track where the consumer’s going. What this information tells the retailer is where a consumer is, how they’re moving around the store, whether they’re dwelling in certain places, like checkout or in front of specific merchandise.

There’s both the real-time application for this technology as well as a longer-term application. And so, as you’re deciding how many people should be in the store manning the registers the next week, you can actually use this information as well.

You’re seeing retailers are being more innovative than I think historically they’ve been given credit. And IT organizations are really starting to be innovators in technology.

Neat stuff, I think."

+ - Why your users hate Agile->

Submitted by Esther Schindler
Esther Schindler writes "What developers see as iterative and flexible, users see as disorganized and never-ending. Why your users hate Agile development (and what you can do about it) shares how some experienced developers have changed that perception.

...She's been frustrated by her Agile experiences — and so have her clients. "There is no process. Things fly all directions, and despite SVN [version control] developers overwrite each other and then have to have meetings to discuss why things were changed. Too many people are involved, and, again, I repeat, there is no process."

The premise here is not that Agile sucks — quite to the contrary — but that developers have to understand how Agile processes can make users anxious, and learn to respond to those fears. Not all those answers are foolproof. For example:

Detailed designs and planning done prior to a project seems to provide a "safety net" to business sponsors, says Semeniuk. "By providing a Big Design Up Front you are pacifying this request by giving them a best guess based on what you know at that time — which is at best partial or incorrect in the first place." The danger, he cautions, is when Big Design becomes Big Commitment — as sometimes business sponsors see this plan as something that needs to be tracked against. "The big concern with doing a Big Design up front is when it sets a rigid expectation that must be met, regardless of the changes and knowledge discovered along the way," says Semeniuk.

How do you respond to user anxiety from Agile processes?"

+ - When Smart Developers Generate Crappy Code->

Submitted by itwbennett
itwbennett writes "If you've ever worked on a team you can probably recall a time when, as a group, you produced work that was not as good as any one of you could have done on your own. Sarah Mei had this sort of sub-par teamwork experience, which she shared in her session at the O'Reilly Fluent Conference this week. Mei 'spoke about a time she worked on a team with really expert developers. Every one of them was someone whom you'd admire, who had previous written code that you and I would boast to have created. Yet, these smart people created modules that didn't talk to each other. And its quality was, to be kind, on the rotten side.' It's not an uncommon story, but why and how does it happen? The answer, says Mei, is that code quality 'is defined by its patterns of dependencies,' not all of which have equal weight. And, as it turns out, team communication is the heaviest dependency of all."

+ - Project management lessons from Game of Thrones->

Submitted by Esther Schindler
Esther Schindler writes "In George R.R. Martin’s masterful series, A Song of Ice and Fire (currently an HBO television show, Game of Thrones), many characters in the fantasy world of Westeros create goals, make plans, maneuver people and events toward the goal they want, and eventually realize their goal. It’s kind of like project management, says Carol Pinchefsky in Everything I Know About Project Management, I Learned from Game of Thrones, but with more entrails.

For example:

Danerys also shows another key quality of good project management: She constantly seeks to learn, and she frequently integrates new information into her plans. That allows her to take advantage of opportunities when they arise, where an inflexible project leader (say, King Joffrey) sees only distractions.

At one point, she tells her people, “I swear to you that those who would harm you will die screaming.” Remember that loyalty to your team is important, although threatening blood and fire might not work in the boardroom.

Well, perhaps it depends on your boardroom."

+ - 13 Geeky Items To (Secretly) Wear To The Office->

Submitted by Esther Schindler
Esther Schindler writes "Not everyone works in an office where superhero t-shirts are acceptable. Sometimes you have to play Clark Kent... but with superhero underwear.

In that vein: Carol Pinchefsky found a few fun things for you to wear to your next business meeting that happen to be subtle and not easily recognizable as geeky. "This way you can maintain your superhero- (or space hero-)inspired confidence while keeping your geeky proclivities on the down-low," she explains. "Plus, if you meet someone who does recognize these items, you may have made a new breakroom buddy."

(Yes, this is a slide show: I admit it. But these things are inherently visual, so it's justified. Plus, it might make you giggle, or rush over to /r/shutupandtakemymoney. I don't foist such things on you usually, do I? Trust me. Or at least buy me the Wonder-Woman underwear and the Starfleet Academy class ring.)"

itwbennett
itwbennett writes "Assuming that Microsoft doesn't choose to implement Secure Boot in the ways that the Linux Foundation says would work with Linux, there 'will be no easy way to run Linux on Windows 8 PCs,' writes Steven Vaughan-Nichols. Instead, we're faced with three different, highly imperfect approaches: Approach #1: Create UEFI Secure Boot keys for your particular distribution, like Canonical is doing with Ubuntu. Approach #2: work with Microsoft's key signing service to create a Windows 8 system compatible UEFI secure boot key, like Red Hat is doing with Fedora. Approach #3: Use open hardware with open source software, an approach favored by ZaReason CEO Cathy Malmrose."

Esther Schindler writes "Think nostalgia isn't what it ought to be? Well, you're in luck. Steven Vaughan-Nichols has written a walloping overview of the pre-Internet online services he used to review for Computer Shopper (which, as it happens, is where he and I first met... perhaps you knew me at 72241,1417 in the early 90s?). Because, you young whippersnappers, before there was the World Wide Web, back when 2,400bps modems were "high-speed," millions of people used online services like AOL, CompuServe, and GEnie to work with each other, gossip, and share Star War jokes. (To my dismay, though, he leaves out Plato Homelink. sniff!) If you have a strange fondness for the sound of a modem connecting and (like me) are still proud of being able to whistle at 300bps, you'll nod along with his trip into the time machine."

jfruh
jfruh writes "The Slashdot readership is probably split pretty evenly into two groups. There are those for whom full-on Internet access has been available for their entire computer-using lives, and then there are those who wanted to use the Net from home before 1991, and who therefore had to use a BBS or an online service. Steven J. Vaughn-Nichols (yes, this guy) takes you on a tour of some of these services, including Prodigy, Compuserve, and of course AOL. This should be a nostalgic trip for the oldsters among us, and a history lesson for Gen Y readers."
