How Do You Organize Your Experimental Data?

August 15th, 2010 08:16 admin View Comments

digitalderbs writes “As a researcher in the physical sciences, I have generated thousands of experimental datasets that need to be sorted and organized — a problem which many of you have had to deal with as well, no doubt. I’ve sorted my data with an elaborate system of directories and symbolic links to directories that sort my data by sample, pH, experimental type, and other qualifiers, but I’ve found that through the years, I’ve needed to move, rename, and reorganize these directories and links, which have left me with thousands of dangling links and a heterogeneous naming scheme. What have you done to organize, tag and add metadata to your data, and how have you dealt with redirecting thousands of symbolic links at a time?”

Preserving Memories of a Loved One?

August 14th, 2010 08:02 admin View Comments

An anonymous reader writes “My wife is dying of metastatic (stage 4) cancer. Statistically she has between one and two years left. I have pre-teen daughters. I’m looking for innovative ideas on how to preserve memories of their mother and my wife so that years down the road we don’t forget the things we all tend to forget about a person as time passes. I have copious photos and am taking as much HD video as I can without being a jerk, so images and sounds are taken care of (and backed up securely). I’m keeping a private blog of simple daily events that help me remember the things in between the hospitalizations and treatments. In this digital age what other avenues are there for preserving memories? Non-digital suggestions would be welcome, too.”

Recycling an Android Phone As a Handheld GPS?

August 13th, 2010 08:31 admin View Comments

imblum writes “So my dad’s antique handheld GPS unit just went toes up and I was considering replacing it for him with an old Android Smartphone. All he really needs it for is hunting and camping (no navigation), so I don’t want to pay for cell or data service. I found the program Mobile Atlas Creator to download map files onto the SD card, and an app called Maverick Lite to view them. Now all I need is to decide on an Android phone. I was considering a Samsung Behold II ($100-200 on Craigslist), but thought it would be nice to get some input from the Slashdot community. It seems like I can get a lot more functionality for the money out of an old Android than I could from a big name handheld GPS. Does this plan sound reasonable? Is there anything I’m overlooking?”

Oscilloscopes For Modern Engineers?

August 3rd, 2010 08:05 admin View Comments

Every few years someone asks this community for advice on oscilloscopes. Reader dawning writes “I’ve just graduated with a degree in Computer Engineering (and did a Comp Sci one while I was at it) and I’m finding myself woefully under-equipped to do some great hardware projects. I’m in major need of a good oscilloscope. I’m willing to put down $2,000 for a decent one, but there are several options and they all seem so archaic and limited. I’m happy to use something that must be controlled through a PC if that gives me more measuring features. What would you, my esteemed Slashdot colleagues, get for yourself?”

String Quartets On the Web?

August 2nd, 2010 08:32 admin View Comments

rueger writes “Lots of people love iTunes. I’m partial to Ubuntu comes pre-equipped for Jamendo and Magnatune. These are great for those of us hunting popular music — but where do lovers of classical music go to find new artists and albums, download music, and generally keep informed, up to date, and satisfied? As my girlfriend put it, ‘I used to go the the big classical record stores downtown, but they’re gone.’ Where do people go to find the newest Ligeti String Quartet recording?”

Equatorial Mounts For Budget Astrophotography?

August 2nd, 2010 08:36 admin View Comments

Timoris writes “With the Perseids approaching rapidly, I am looking for a good beginner’s motorized equatorial mount for astrophotography. I have seen a few for $150 to $200, but apparently the motor vibrations make for poor photographs. Orion makes good mounts, but are out of my price range ($350) and the motor is sold separately, adding to the price half over again. Does anyone have any good experience with any low- or mid-priced mounts?”

How Can an Old-school Coder Regain His Chops?

August 1st, 2010 08:41 admin View Comments

DonLab writes “I was a proficient software engineer in the 1980s, writing hundreds of thousands of lines of ALGOL, FORTRAN, COBOL, and Pascal programs, as well as working in 370 and 8080 assembly language & pre-relational DBMS systems. My hands-on programming career ended when I became a freelance analyst and designer, ultimately retiring young in the early ’90s. Now I’d like to reenter the field, but I’m finding that I know nothing about today’s post-C languages, programming tools, and computing environments. I wouldn’t know where to start learning C++, PHP, Java, HTML5, or PERL, much less how to choose one over the other for a particular application. Can I be the only pre-GUI software designer or hobbyist searching for a way to update his skills for Windows, iOS, or Android?”

Alternatives To Paypal’s Virtual Credit Card Service?

July 31st, 2010 07:02 admin View Comments

An anonymous reader writes “Paypal has quietly killed the Paypal plugin and the related virtual-card service. The service generated on-the-fly, one-time-use credit card numbers. When I called in and inquired about the service, I was told that the service has been discontinued, but may be relaunching something similar depending on interest. They are treating inquiries as a sort of petition, taking down names and contact info. The forums seem to be a lost cause, as no Paypal reps have replied to the numerous posts regarding virtual cards being discontinued. Does anyone know of a good alternative source of one-time-use credit card numbers?”

How Should a Non-Techie Learn Programming?

July 30th, 2010 07:45 admin View Comments

CurtMonash writes “Nontechnical people — for example marketers or small business owners — increasingly get the feeling they should know more about technology. And they’re right. If you can throw up a small website or do some real number-crunching, chances are those skills will help you feed your family. But how should they get started? I started a thread with the question on DBMS2, and some consistent themes emerged, including: Learn HTML + CSS early on; Learn a bit of SQL, but you needn’t make that your focus; Have your first real programming language be one of the modern ones, such as PHP or Python; MySQL is a good vehicle to learn SQL; It’s a great idea to start with a project you actually want to accomplish, and that can be done by modifying a starter set of sample code (e.g., a WordPress blog); Microsoft’s technology stack is an interesting alternative to some of the other technology ideas. A variety of books and websites were suggested, most notably MIT’s Scratch. But, frankly, it would really help to get more suggestions for sites and books that help one get started with HTML/CSS, or with MySQL, or with PHP. And so, techie studs and studdettes, I ask you — how should a non-techie go about learning some basic technological skills?”

Internal Costs Per Gigabyte — What Do You Pay?

July 29th, 2010 07:29 admin View Comments

CodePwned writes “I recently took over a position at a rather large company where I discovered my group was paying $30 per gigabyte per month! That’s $360 per year per gigabyte to our own IT department. While I understand costs are different depending on the scale, redundancy, backup and support methods, there doesn’t seem to be any good papers on what range you should expect your costs to be. So far, my research shows an average of $1 per gigabyte or less for internally hosted space. What do you pay?”
