Professors Slam Java As "Damaging" To Students

Paulrothrock Re:tasty (1267 comments)

Most of my professors had no real world experience, either. So, teaching things like team dynamics and working within a project schedule were really beyond their expertise. Granted, I've been quite successful, but I attribute most of that to my abilities, not what I learned in college. College just got me a piece of paper that opened the door.

This is why I'm thankful I basically flunked out of the CS program at Penn State and went into their IST program. I got a much more well-rounded education, learning everything from database normalization to computer networking to web app programming and XML integration. They usually let us use the languages and applications we felt most comfortable with.

Because of this, I am able to do pretty much everything from debugging Perl to setting up a database to writing a shell script to hardcore coding. (Right now I'm working on Fitnesse fixtures in Java.) And those folks in CS programs? They keep coming to me to fix their computers. They've got a great theoretical knowledge, but little working knowledge.

What Should our National Broadband Strategy Be?

Paulrothrock Paulrothrock writes  |  about 7 years ago

Paul writes "Senator Durbin is asking for your input on the national broadband strategy. The site Open Left, who is hosting the discussion starting at 7PM EDT tonight, has proposed three principles for broadband in the US:

  • Broadband access must be universal and affordable;
  • We need to preserve an online environment for innovation; and
  • We need to ensure that broadband technology enables more voices to be heard.


What are your thoughts?"

Getting Cell Phone Reception in a Basement

Paulrothrock Paulrothrock writes  |  more than 10 years ago I'm finishing a walk-out basement to live in. It's great because we can set it up and paint it like we want, and I can build in things like networks and speaker wiring to get the ultimate geek abode, and it's only $450 a month. The only problem is that we don't get cell phone reception, since we're at the bottom of a hill and we're encased in cinder block.

We don't want another bill for a phone line when we don't really need it, so I had the idea to build a cell phone repeater. This handy little device has two antennas and a bi-directional amplifier. One antenna is outside the house, probably on the roof. This picks up cell signals and sends them down to the amplifier. This routes the signals to the internal antenna at a low wattage (enough to cover our 2400 square foot basement). The internal antenna picks up the signals from our phones and sends them, through the amplifier, to the external antenna and into the network.

First question: How would I go about making one of these? I would imagine I could pick up the materials for under $150 from Radio Shack, and I'm pretty confident I could solder one of these together. But I can't find any plans. I googled for them at work yesterday, but all I could find was people who wanted to sell me one... for at least $500. And I couldn't find personal ones, just commercial ones that cover 20,000 square feet. (I don't really need it outside, since we actually get pretty good reception in the backyard.)

Second question: Would I be breaking any laws doing this? I wouldn't think so, since I'm using very, very low wattages (maybe a 5-10X stronger than a cell phone on the external antenna, and about the same as a cell on the internal antenna). And I'm not providing a service, just amplifying a signal to provide myself with better service (which I'm pretty sure T-Mobile wouldn't mind, since everything else about them is perfect).

Third question: What about a passive repeater system? According to this page, they don't work because the signal strength from the tower is so low. But they're also the people who want me to give them $650 to get reception in the basement. This would be even cheaper than hacking together a BDA, since all I'd need would be two $20 antennas and $5 of low-loss cable.

Fourth Question: What about this thing? Could I add a transceiver to the phone connector to make a BDA? I really, really, really want to avoid having to plug my phone into something. The antenna connector on my phone (T610) is underneath a little button, and I have to turn off the phone, open the battery cover, remove the button, plug the antenna cable in, and put it all back together. And what's the point of this when I got a cell to not have cords?

If anybody could answer my questions, that would be great. Circuit diagrams or instructions would be excellent. The only ones I could find are for a wired 2.4GHz signal booster, not a repeater.
