Comment: Single-ride exact price ticket? (Score 1) 240

by Tmack (#46220845) Attached to: How To Hack Subway Fares Using Fare Arbitrage
More so than the efficiencies, unless you went through the trouble of getting an exactly priced BART ticket for that single trip, you will be swapping tickets that potentially still have more cash value on them. Most commuters have switched to using Clipper card (rfid based pre-payment system) which works well for BART but is a craptastic company to deal with and is setup horridly on the other transit lines (Caltrain specifically). Simply the time I save not having to stand in line to buy a paper ticket at a machine, reduced to the exact ride price (look it up on the fare chart, hit buttons many times to reduce the default $20 ticket to the exact price if its credit, or spend time counting out change to feed the thing) each trip and instead just swipe my wallet over the turnstile and walk through is worth more than any potential saving, if I even happen to ride a route that has this arbitrage opportunity (doubtful).

Sure, but the devil is in the details. WHERE do they park? Cabs must park somewhere visible where anyone can see them, a public space on public property, but these other "things", can be anywhere, in a private parking lot, or somewhere else equally privately owned.

...

How does that matter? The Uber driver could be (and has been a few times I have scheduled a pickup for a 3am flight from SFO) at home in bed. They are only providing a ride from point A to point B for customer X, after customer X contacts Uber to schedule the ride (ie: a Chartered trip). They are not soliciting rides directly, which is THE differentiator between Uber/Lyft/etc and a Taxi service. Once that charter is completed, they could go on to their next assignment or go home. Taxis circle hoping to get either a dispatch or someone flagging them down on the street.

+ - Java 6 is EOL'd by Oracle

Submitted by Tmack
Tmack (593755) writes "Not completely unexpected, Java6 has reached EOL. This tidbit shows up in Oracle's Java6 FAQ page, recommending everyone update to Java7:

Java SE 6 End of Public Updates
Oracle no longer posts updates of Java SE 6 to its public download sites. All Java 6 releases up to and including 6u45 have been moved to the Java Archive on the Oracle Technology Network, where they will remain available but not receive further updates. Oracle recommends that users migrate to Java 7 in order to continue receiving public updates and security enhancements.

Apple just pushed its update 16 which is Java6u51, likely to be one of their last Java6 updates."

Ask yourself, is it worth it for a bank, gmail, the FBI to invest $9k (or more, for the higher-end device), or risk $X0,000 * $NumberOfCustomers in legal fees and triage and incident response if a bad drive were to escape into the wild? I can guarantee you a single investment of $9k is a no-brainer and is dirt cheap compared to any incident response for stolen data. Not sure what "simpler methods" exist than: 1. insert drive, 2. ??? 3. drive is dead/data gone. When you have to get rid of multiple drives a week, things like this are a must-have.

Those fills of random bits work real well when the drive fails and can no longer be accessed.... A motivated entity could possibly recover the bits still on chip/disc, its up to the organization to decide how to dispose of the drive and if its worth their/their clients' interest in making sure the data is not recoverable. I wouldn't want my bank to simply toss a bad drive out in the normal garbage.... -T

Described here (w/dump): https://lkml.org/lkml/2009/1/2/373

Simple version:
"dont kill the messenger" except when the messenger is going to kill you. Its printk sending notice that the leap second happened that deadlocks against the timer doing the leap second (both vying for xtime_lock). Call it a "feature" of the NTP code. Hence the "turn off NTPD" workaround, if NTP doesnt get notified it should implement the leap second from somewhere upstream, it wont notify about it to the kernel, and the printk shouldnt happen.

The vulnerable kernel versions (prior to 2.6.29) are still common amongst older versions of popular distributions (Debian Lenny, RHEL/Centos 5) and embeded/black-box style appliances (Switches, load balancers, spam filters/email gateways, NAS devices, etc). Several vendors have released patches and bulletins about the possibility of a repeat of last time. Are you/your team/company ready? Are you upgraded or are you going to bypass this by simply turning off NTP for the weekend?"

As many others above have posted, though none got any mod points for (yet)...

Its free, opensource (GNU), widely available as a standard package to most platforms, etc. You create a password file, encrypt with gpg, then sign it with each user's key that should have access to it (requires all users to have proper gpg keys setup). When someone leaves, you revoke their key from the file and they can no longer get to it, without having to do much else. If thats too complicated, just do a basic crypt (gpg -c) and share that password around. Then if someone leaves just decrypt and re-encrypt with a new password.

Then go to dealextreme.com, or I think they're also at dx.com now. There you can get cameras, and the video balun's to make it simple to use cat 5 to run your cameras. A camera is about $20 for a decent night vision one, and the balun set (8 baluns to run 4 cameras) were about $25.

Can some one point to the airport exclusion? Or where congress amended the constitution to allow this?

They simply changed the interpretation of "unreasonable". After all you may be a terrorist, citizen.

No, its simple congressional logic: that since you are flying on a commercial airliner, and terrorists have flown on and blownup/crashed commercial airliners, you must be a terrorist, therefore probable cause exists to search you with overpriced gadgets that serve to slow down the lines of passengers (unless you pay them more $$ to bypass them) and not detect any of the things the manufacturers promised they would, but find everything else that could make them run your bag through multiple times... while said manufacturer, and their share holders (coincidentally people that helped construct/pass the bills making this mess happen) is raking in taxpayer $$.........

The output of the 3d printers will be made of a completely different substance than the specialized car parts. The different substance will likely have different heat and pressure tolerances, different tensile strength, and so on. It probably won't work, and could cause damage.

Maybe, but they would make a great pattern to build a mold so that the part could be reproduced with the proper materials.
