Waze Causing Anger Among LA Residents

Jmstuckman Re:Move to a gated community (589 comments)

Do this, and all the bicycles will be forced to ride on the main arteries. Then, the same people who were complaining about traffic on their streets will probably be complaining about arrogant cyclists who think they own the road and slow everyone else down.

Not a good idea.

Google Suggests Separating Students With 'Some CS Knowledge' From Novices

Jmstuckman Common in foreign language classes (304 comments)

This reminds me of a common practice in foreign language classes -- if a student shows up to a language class (e.g. Spanish) and is obviously too advanced for the level, then the student will not be allowed to return to that class. This is partially done for reasons of fairness (getting an A that's too easy), but mostly because it's actively detrimental for the basic students to have an advanced student in the classroom. They speak too quickly for the other students to understand, and their presence can be actively discouraging in an environment where many are struggling.

My college has long placed students with some CS knowledge in an "advanced" section of the intro programming class to avoid this issue.

Ubuntu Gets Container-Friendly "Snappy" Core

Ubuntu Gets Container-Friendly "Snappy" Core

Jmstuckman I Don't Get It (149 comments)

Developers of snappy apps get much more freedom to bundle the exact versions of libraries that they want to use with their apps.

...Did this guy just say he brought DLL Hell to Linux? Help me to understand how he didn't just say that.

Too late -- Ruby on Rails has already brought DLL Hell to Linux. I challenge you to install a Ruby on Rails application without having the exact version of Ruby and its dependencies that was used to develop it. This is why almost everyone uses Ruby version managers such as RVM, and you will not have much luck installing Ruby packages from your OS maintainer's package repository (and I certainly hope that none of your Ruby code is pulling in something with a security vulnerability.)

I'm guessing that this solution was built by the same crowd that did Ruby on Rails.

The Most Highly Cited Scientific Papers of All Time

Jmstuckman Re:When is something well-known enough to not cite (81 comments)

Maybe the PP works in Computer Science. In CS, it is common for authors to typeset the entire paper themselves using a style file provided by the conference or journal.

We actually *prefer* typesetting papers ourselves because our manuscripts are all in Latex anyway. Journals that want to prepare their own camera-ready copies (in particular, non-CS journals) often have trouble accepting Latex source are are accustomed to taking all of their submissions in Word...

Automation Coming To Restaurants, But Not Because of Minimum Wage Hikes

Jmstuckman Workforce vs. number served (720 comments)

More customers served per minute -> fewer workers required per customer -> fewer workers. This development will inevitably reduce workforce.

Ask Slashdot: How Would You Build a Home Network To Fully Utilize Google Fiber?

Jmstuckman Running Ethernet cable not always difficult (279 comments)

Is your router on the first floor, and does your house have an unfinished basement (no finished ceiling)? If so, you can easily run Ethernet cable through the basement. Just drill one hole in the floor near the fiber device, and another hole where you need your computer. Run the cable into the basement. This is easy to hide if you have carpet -- if you have hardwood, drill it near an existing opening (like the heating duct).

The Great Lightbulb Conspiracy

Jmstuckman Warranty returns for GE CFLs (602 comments)

The warranty for GE CFLs guarantees that the bulb will last a certain number of years at a given duty cycle. I keep the receipts for all GE CFLs that I buy (writing identifiers on the bulbs themselves), and I always make a warranty claim when a bulb doesn't last as advertised.

A few have burned out before their rated lifespan, but most have performed as advertised. For the bulbs that did burn out prematurely, GE has always honored my warranty claims quickly.

Artificial General Intelligence That Plays Video Games: How Did DeepMind Do It?

Jmstuckman How to do it. (93 comments)

Advances in Deep Learning have made it far easier to extract features from vision -- in fact, feeding pixels straight to the neural net is pretty close to being all you need to do.

Take a look at these slides and read about convolutional neural networks: http://www.slideshare.net/0xda...

Washington DC To Return To Automatic Metro Trains

Jmstuckman What's wrong with American drivers? (179 comments)

> What's wrong with American drivers?

DC's metro trains were designed to be operated automatically the vast majority of the time. Hence, the acceleration and braking systems were optimized for automatic operation (as opposed to manual operation) and it is difficult for a human driver to control the train's movements precisely and smoothly.

PHP 5.6.0 Released

Jmstuckman Re:Now almost as useful as python was 5 years ago! (118 comments)

PHP is a horrible programming language, but I know why people like PHP applications -- the ability to install an application on a LAMP stack by just untarring a single archive into the deployment directory is priceless.

Last time I tried to install a Python web application, I had to give the installer root privileges to install a bunch of junk in some system-wide module directory. No thanks.

Last time I tried to install a Ruby web application, I ran into a bunch of snafus related to newer versions of Ruby not being backwards compatible with older code, and discovered that the "right" way to do it was to install a whole new package management system that wasn't in sync with my OS's own package manager. No thanks to that, either.

Ask Slashdot: Bulletproof Video Conferencing For Alzheimers Home?

Jmstuckman Did something like this recently (194 comments)

I did something like this recently with Skype and Ubuntu 13.10. You can set up auto-login on Ubuntu, auto-start on Skype, and set up Skype to auto-answer and auto-activate the camera. In theory, it could get torpedoed by some kind of random dialog box, but it hasn't happened in two months. To make a it a little more bulletproof, you could set up a cron job that reboots the system nightly.

One warning: since Skype was acquired by Microsoft, the standard Skype login dialog was replaced with some kind of weird integration to Microsoft's outlook.com single-sign-on. When Microsoft is having system problems (like they were a couple months ago), it appears to lose all of the single-sign-on tokens, which will drop the system back to the login page, and you will be stuck. However, this only happened once in the past couple months. (Yes, things worked far better before Microsoft bought Skype, but it's not a lost cause.)

Geographic Segregation By Education

Jmstuckman Moving is more natural (230 comments)

Absolutely right. I grew up in an economically disadvantaged area, went to college, and settled in one of the best-performing metro areas in the country. My classmates who skipped college are still there, driving 1-2 hours each way to the closest job they can find, and enduring the double disadvantages of lacking a college degree and living in a depressed area.

When one is living dangerously close to the poverty line, moving away from friends and family will be perceived as unacceptable risky. Only the most ambitious will leave, and most of those people went to college anyway.

The Future of Wearables: Standalone, Unobtrusive, and Everywhere

The entire comment was apparently plagiarized from an article on another site. Given this, I'm wondering how it got all the way up to +4.

Autonomous Trucking

Jmstuckman Rail? (142 comments)

As the previous AC post alluded, the particular requirements of freight and passenger transport don't mix well. The United States moves a massive amount of freight by rail, with very few long-distance rail lines being totally dedicated to passenger transport. Unfortunately, the unique requirements for passenger and freight traffic don't mix well.

Freight trains travel at lower speeds than the ideal passenger train, and acceleration and deceleration is extremely slow and inefficient. In the USA, the rail lines that share track with freight suffer from very slow average speeds and long delays, as they get stuck behind freight trains and are sometimes forced to stop and wait for conflicting traffic to pass. This results in long delays (both on long-distance lines and on local commuter lines which share freight tracks into the city) and the inability to add extra trains to improve service. Furthermore, for a passenger train to survive a crash with a freight train, an extraordinary amount of extra mass must be built into the passenger train, raising costs considerably. (Look up the Wikipedia page for the USA's Acela Express rolling stock.)

Ask Slashdot: Hosting Services That Don't Overreact To DMCA Requests?

Jmstuckman John Smith? (148 comments)

I thought that perjury was a criminal offense, not a civil one, meaning that one cannot "take them to court" -- you can only report it to the FBI and see if the US Attorney will choose to prosecute. Am I missing something here?

In 2012, Facebook Altered Content To Tweak Readers' Emotions

Jmstuckman Re:consent (130 comments)

From a legal standpoint, for an activity to be considered "research", it must be "designed to develop or contribute to generalizable knowledge". http://www.virginia.edu/vpr/ir...

When a website uses A/B testing to improve its own internal operations, it's seeking to privately develop limited knowledge on its own operations, rather than general knowledge. This puts it outside the scope of US federal regulations on research, which have been narrowly crafted to avoid regulating commercial activities like these.

Given these criteria, Facebook was surely engaged in research.
