Ok, as someone who has long been very close to the rail industry, a few points:

1. "...the Long Island Commuter Railroad (LIRR) in New York City, which has no freight traffic" - Incorrect. The LIRR also is host to the New York & Atlantic railway, a freight line which does indeed operate on LIRR lines daily. Average train gross weight is about 1,200 tons for each freight on that line, not 100 tons.

2. "FRA staffers point out that it is unfair to compare US buffering standards with those in Europe because passenger rail in the US has to contend with more (and heavier) freight traffic." - They are quite right to do so. The US plays host to the highest density of freight rail traffic in the world with most trains exceeding 5,000 tons (some closer to 15,000).

3. "In both Europe and Japan, a competitive business exists in the DMU marketplace. But that market is off limits to US transit agencies because the FRA has effectively created a trade embargo." - Incorrect. In San Diego, the Sprinter lines use Siemens Desiro DMU's, a light design totally unadapted for the US Rail network as far as weight goes. The line also plays host to freight trains at night. How they got around the weight requirement, I do not know. Furthermore, the San Diego Trolley has the line from downtown to El Cajon by way of Lemon Grove. That line also plays host to freight at night - a streetcar line! The market is indeed open, but the trick agencies use to get around the requirement is a bigger question.

4. "The FRA proposed rule would only allow Quiet Zones exemptions at crossings that had been improved with "four-quadrant" gates and curb medians." - for good reason! Many fatalities happen at grade crossings and horns are one of the only really efficient ways to keep people off the tracks. Most other nations have few crossings, preferring grade-separated rights-of-way. However, in the US, drivers are often grossly idiotic and don't pay attention. Not how many grade crossing accidents you see on YouTube...

That said, it is indeed a major issue that the FRA rules apply to any rail line connected to the freight network that spans the nation. It would be far better if the regulations made clear exceptions for trains on passenger-only lines, hours of operation, etc.

For example, let's look at CalTrain. The main line up the peninsula only sees freight traffic at night. By setting operational rules that restrict speeds near freight trains, etc, this would allow much better equipment for CalTrain while continuing to let freight run at specific times.

The FRA very much needs to get with the program and allow better conditional standards.
A CS graduate with a GPA in the low 3's is quite employable.
The math field is full of seniors graduating with GPAs in the low 3's that can't find jobs. Lots of them have done a
little programming, so it is hard to stand out. There is an
excellent chance you will be sending out resumes for a year without a job offer, looking less employable all the time.

If you can get into a CS Masters program (doesn't have to be a top school), you would be much more employable after a year of CS classes than you are now, even if you are far from getting a degree.

Alternately, can you delay graduation a year? Is it feasible to spend another undergraduate year minoring in CS?

Palo Alto - Tinfoil Security (http://www.tinfoilsecurity.com) - 500startups company

About Tinfoil Security:

Tinfoil Security is the simplest way to secure your website. To the user, we provide an easy-to-use reporting interface that tells you where we found vulnerabilities, what they are, and provides a step-by-step wizard of how to fix them. Behind the scenes, we're crawling the site looking for every potential input vector and attempting to infiltrate, just like any external hacker would. The catch is we do this non-maliciously and without leaving a trace. Sound interesting?

We're looking for incredibly smart guys (or girls) who like to get their hands dirty. If you don't know the answer, find it. If you can't find it, build it; but don't reinvent the wheel. If all the wheels suck though, build a better one.

We're revolutionizing the stale and boring security industry, and making website and mobile security accessible to the world, so no business has to continue being the "low hanging fruit." It's absurd that security is only understood by so few developers and business owners in the world, when so much of it is actually pretty simple to understand. We want to change that. Join us.

About you:

You'll be employee #1.

Our entire stack is Ruby at the moment, but we have a strong affinity for Python, Scala, and C, in no particular order. We're of the mindset that you pick the best tool for the job, much as you wouldn't hammer in a nail with a wrench (unless you didn't have a hammer and really needed to get it done fast).

You'll be in charge of a large project, and will be given the ability to take charge of it and make it your own. On the flipside, you should be willing to take on that challenge.

More than anything else, I can guarantee you'll have a boatload of fun, learn a ton, and produce software people really care about; lots of people.

We offer significant equity, market salary, benefits, your choice of equipment, etc. We're based in Mountain View and are looking for people that can hack in the office with us.

Please get in touch -- borski@tinfoilsecurity.com -- we'd love to chat. :)

It takes much less time to build a new bridge from scratch than to replace half of a bridge in-place. From the Bay Bridge FAQ (http://baybridgeinfo.org/faq):

"One of the greatest challenges in performing any seismic safety work on the Bay Bridge is that traffic must be kept moving. This has required the construction of temporary structures, and shifting of traffic from the existing bridge to the temporary structures. Major construction and demolition work is often scheduled during nights and weekends in order to minimize disruption to commute-hour traffic. This elaborate scheduling has extended the length of time that it takes to complete the seismic safety work."

Ask HN: How does a n00b get started on open source projects?
My fellow hackers,

I just started messing with Rails, but in a big way. That does not mean I've done anything great, I just have been learning from every source I could. I think I'm ready to stand my own two feet now (or at least try).

How do I start looking at, and messing with, simple open source projects? I'd prefer projects that are well documented / have tons of comments, are small, standalone, and simple.

For example, a good initial project might be a simple form, that lets users sign up, and store data in a db, and be able to call it (kind of like bare-bones Wufu). Another might be just creating multiple relational dbs and messing with them.

Also anything that teaches good jQuery integration, CSS etc. Also, if anyone would like, I don't mind putting up my crap work somewhere for you to dissect. :-)

Always grateful.

What the web needs is a UI demo site. You could submit a page that was a demo, and it'd have some metadata in the markup to describe it, and then that would be iframed into the site - then there'd be a header to navigate all the demos. It could be called UIpalette. Any takers?

_delirium pointed out the regulation that allows Sprinter and San Diego Trolley to get around the weight requirement in this comment: http://news.ycombinator.com/item?id=3060835

In doing some more research, Utah's FrontRunner has a completely disconnected network that allows them to get around the weight requirement. Apparently they went with standard US commuter equipment (MPI locomotives and Bombardier coaches) because of grade crossings and collision concerns. No sense in having a super-light train at high speed with grade crossing that carry many trucks.
I'm used to see 10 trains on an electrified railway line an hour in each direction, some of them very light EMUs, longer locomotive-hauled passenger trains and heavy freight (ok, heavy is ~2000 tons). With the last deadly accident with a passenger train hitting the freight (and falling from the bridge after that) in... 1970.
Monorails and Maglev are remarkably expensive and inefficient, so unfortunately I doubt they'll ever be a viable alternative.

Rail operators are occasionally able to get waivers from the FRA to run non-compliant rolling stock. Caltrain was awarded such a waiver for a future rolling stock purchase, and the Sprinter was awarded one as well. Typically the FRA requires that there be some sort of temporal separation between the trains, which could mean freight only running at night, or it could mean all trains on the line have some form of electronic PTC (positive train control) that guarantees separation between trains. The freight lines have been fighting PTC for several decades, but they're finally being forced to implement it (of course the FRA hasn't set much of a standard, so there's going to be a dozen different incompatible systems, yay).

The problem is that the waivers are arbitrary and one-offs. There's no standard for light passenger rail in the US, there's just a bunch of hyper-specific waivers for each case and operators must re-apply if their rolling stock changes. So if caltrain wanted to switch from UIC-compliant Siemens Desiro trains to a UIC-compliant hitachi train, they'd have to apply for another waiver.

To top it all off, the FRA's own studies showed that their "buff strength" standards are more dangerous than the more modern energy-absorbing crash structures mandated on European and Japanese lines.

The FRA really does need to be reformed.
Yep, signaling and operating rules are the biggest concern. If you run a railroad properly, you reduce the risk at far lower cost.

Sites like Hacker News comb the net and bring interesting web sites and articles to my attention, in a world where everyone can be a writer. And in a world where everyone can be an artist, musician or movie maker, there will be ways to filter out the good stuff from the bad. "Getting lost in a sea of mediocrity" is entirely avoidable.
This is a great idea but it doesn't seem to work well yet.

The music 'industry' is huge and complex. They're like Righthaven, Microsoft, Linux, the startup scene, and all other players on every side of helping/exploiting artists.

The RIAA has nothing to do with small record labels like the one I manage, struggling to promote great but fame-less musicians. I suppose they do effect us in that they pose an omnipresent threat of arbitrary litigation at any moment.

What's the difference between Sony, some small tour booking company, and a music venue? I guess from the outside it all looks the same.
Per-Element FullScreen API
Yes Caltrain (actually the Peninsula Corridor Joint Powers Board that owns the track) has a clause in their contract from when they bought the line from Union Pacific that states they can start freight abandonment proceedings if they make a significant change to the line. It's generally believed that was put in there in case they wanted to convert the line to BART, but in theory it could be brought into play for a Caltrain electrification or the HSR project.

Caltrain has so far, however, refused to go down that route. Apparently the one freight train per day is too much to lose.
