Your boss may not be wrong for patenting your work.
If your work contributed to or is a piece of code or software that your company relies on for revenue, what happens if he doesn't patent it? Someone else does. And then turns and sues your company for using "their" code. It's not hard to see where that leads. Company going under, you and your boss getting fired, etc, etc.?
I don't like it any more than the next Slashdotter, but it's not hard to picture that exact scenario.
You may have to just grin and bear it.
Bottom line -- software patents have their advantages and disadvantages, but refusing to file a patent seems like a bad career move to me.
Your cause, while subjectively nobel, will be a very quiet and lonely one. Fired or not.
If it makes you sleep better at night, go on ahead. Frankly, I am more interested in paying my bills AND helping keep my employer in business.
Mod up. This is the best comment i've seen on this article.
We use this gear on our community wireless network (SeattleWireless) and I always recommend it. Don't waste your time with linksys hacks, non-waterproof cantennas that melt in the rain (believe me, i should know, it rains a lot), and cheap imitations.
belial's idea is cheap, effective, and reliable. I'd recommend a pair of nanostations, as i think a powerstation would be overkill. Can't go wrong for $80 a pop.
Think for 2 seconds... they are suing because of the effects of "GLOBAL" warming. Picking them up and moving them somewhere else is only a stop-gap measure. GLOBAL == everywhere. In other words, its time to move on.
The premise of the lawsuit sounds silly, but it sure did get everyone's attention. But think of it this way: You have a group of about 400 people in "the middle of nowhere" about to see everything they know flooded and eroded out of existence. They are having trouble getting noticed. This is a hurricane Katrina in the making. The problem is, half of americans I have met don't even know Alaska is even a state -- or even where it is on a map. The Inuit as a whole (including all regions) have repetitively petitioned the government to take a look at what's happening to their lives.....they have even gone to the UN declaring a human rights crisis. Hunters falling through thin ice, dwindling food supplies, hungry polar bears being forced to forage villages for food/garbage/animals/humans. Lets say in San Francisco had paper thin sidewalks in random locations, causing people to fall to their deaths, and man eating lions roaming the streets. Thats absolute nonsense -- nobody would let that happen, right? If it was allowed to persist, that would almost be a human rights issue..and..hmmm..back to where we started.
In other words, if they have all this, they've already been assimilated. Think about it for a minute... they're suing, aren't they? Sounds pretty much like they've absorbed non-native American culture pretty well.
Never did I say that the people here live in igloos and are unaware of modern society, requiring government protections of some sort. Thats absolutely absurd. These are real people watching their entire town be destroyed by the forces of nature, caused by global warming or not, it doesnt matter. They are being denied the very disaster relief funds that we in the rest of America take for granted. Even New Orleans (eventually) got this. I haven't been to this particular location, but most arctic natives are very close to their native roots compared to any other native american group. They have never objected to accept new technology as it came along -- assuming it made sense. Its a mix of old and new ways. I know one particular whaling captain on the north slope that takes along his iridium satellite phone on hunts in a seal skin boat. He's got a day job, but he goes on the hunt and shares food with other people in the town. While living wage jobs are usually provided, there is still quite a bit of poverty, and every bit of food helps. Food by air freight is extremely expensive, even in jet serviced locations.
The arctic environment is extremely harsh, unforgiving, and I believe that for better and for worse, technology has been somewhat of a help. I think everyone in america has the right to enjoy heat, running water, electricity, and a modest gravel strip for air taxi / medivac if you are dying. There are people in Florida/etc with plenty of money to move out of harms way, and yet they get billions of dollars of funds to help out in times of need. I sometimes wonder why people live there, but this is still a very rich nation that should take care of its citizens, whether it be a native village in Alaska with a vibrant hunting culture (really 'livin' off the fat of tha land' -- like everyones dream) or the coffee addicts in Seattle, washington.
Apparently you have never performed or seen any logistical operation in rural Alaska. a 10 lane freeway does not run from Anchorage to Kivalina. It is a fly in only location with a short gravel runway. Nevermind the fact that the location of the new city would need to be moved inland to an undeveloped location which would need a new landing strip.
The summer (construction) season would be very short, with possibly one yearly shipping window where heavy equipment, houses, and various pieces of infrastructure could be loaded onto the shore. It would have to be positioned inland. Labor rates would be ridiculously high, and its difficult to find experienced contractors for arctic construction. Contractors would have to be routinely ferried between Anchorage by charter aircraft. Shipping costs would be about $0.25/LB by boat and $1/LB by aircraft (and air freight would likely be limited by the type of airfield available). Anyone how much a house weights?
A brand new town in northwestern Alaska would require and not limited to: landing strip, communication facility (satcom), telephone, power generating facility, electrical systems, storage facilities for diesel fuel, water supply, water treatment facilities, something like utilidor (insulated everything-in-a-tube conduit for water, sewer, etc), and manufactured buildings for various government, commercial, and residential housing. Keep in mind that in a lot of parts of Alaska, there is something called permafrost. This makes even the most basic construction difficult, and usually requires drilling through this ice and insertion of pillars to anchor buildings.
When a couple of villages on the north slope were "modernized" with running water and sewer systems (Utilidor), hundreds of millions were spent by the North Slope Borough in 1980 dollars.
Yes, a town for 400 people can cost $400 million easy in rural Alaska. And when the stuff really hits the fan, those oil and gas companies are getting off scott free, and the federal government will have to pay for it. And believe me, with the way things are going, it won't be the last relocation of an American town or city. $400M is going to look like a bargain.
And for those of you who say "why don't we just put them on a plane and fly them to XYZ and buy them a house", why not show a little compassion? You apparently don't understand. You cannot just pick up a group of people and relocate them from a place they don't want to leave. How would you like it if China took over your local jurisdiction, and decided to relocate you to mainland China, gave you 20 yuan, and patted you on the head, and sent you off..?
What company, in their right mind, wouldn't patent multitouch gestures and protect themselves? I'd much rather see a company patent this and actually use the technology than a troll come along and assert their litigation power on every company who adopts a defacto standard.
Every 8 hours means 3 launches a day, or 1095 launches a year.
With even the cheapest base station hardware, helium, balloon (at say, $5000 per unit), costs would exceed $14.6M/year per site.
This does not include the labor to continuously manufacturer, transport, and launch equipment.
At a rate of $50/month per subscriber, you would need about 25,000 to break even on base station--hardware alone. This does not include the uplink facility, bandwidth costs, and business administration costs.
I have seen quite a few telemetry balloon launches and return of balloon hardware has never happened even once. Balloons seem fall in the most remote areas, getting caught in trees, landing in the ocean, etc. If a human ever encounters the hardware, they certainly are not very honest about returning it. Even at a modest recovery rate of 1%-5%, it wouldnt be worth the trouble. This sounds like a major environmental hazard too.
Whoever wrote this business plan is on crack. $15 million a year for the equivalent of 14 base stations?! In a rural area? Instead of using grain silos?
And what is this 'floating gently back down to earth' stuff? Unless they have a parachute, the tranceiver will not be floating gently back down to earth when the balloon pops. It will be plummeting
The FAA has quite a few requirements for balloons, including a) payload to have a parachute apon balloon failure b) radar reflectors so ground controllers and aircraft can see them c) remote "self destruct system" to release balloon, among others.
I think everybody on this planet deserves the benefits of modern healthcare, even if they forget dosages from time to time.
Are pills your life? Most commonly not. Are some people prone to forgetting random tasks such as a 3 second event each day? Yes, myself included.
I haven't taken a prescription medication in over 10 years, but just recently, I have had to take one for the last several months. I can't tell you how many times ive dumped out that pill bottle and correlated the current date, number of pills, with the date of the prescription to determine: a) if taking another pill equals a double dose b) if i even took a dose that day
I agree, one of those monday, tuesday, wednesday, etc. boxes grandma had might do the trick. Or perhaps i should pop it into my iphone calendar on a daily recurrence.
What people really need is pill management. They need to be reminded of this. Most want to take their pills (unless they are mentally ill, an entirely different issue), and feel bad when they miss them. Like many other people out there, I want to get better. I need something to manage that.
Greenhouse gases aside, its important to point out that the big losers in corn ethanol lobby are the third world (or more PC, the developing world).
The demand for ethanol, driven mainly by 10%, 20%, and E85 mixtures has driven corn commodity prices sky high. Remember, corn is still a food product that people eat!
That corn you are burning in that E85 car of yours is quite literally starving women and children in a large part of Africa. They are completely priced out of the market. I am all for the environment, but there are much better ways to go about it. Here's a start: lets not use food, especially staples like corn.
All LEDs inversely function as light detectors, even while emitting light. All that is really needed is a display controller that is designed to detect this reverse current flow. It would be interesting to see such an application. The only thing I have seen so far is a traditional LED matrix that works like a touch screen to turn each individual LED on and off.
Maybe to some high tech geeks, voice may seem to be the least used function. But as someone in the cellular industry, I can tell you voice far exceeds any other type of usage.
If anyone ever does push that mystical "web" button, its on accident. Actual usage of "value add" data services is very minimal at best. A vast majority of customers just want a phone for one purpose: voice
I do not understand what WiMax or WiFi has to do with Wireless WAN services either.
The word "pod" means a shell, casing, or housing that stores STUFF. There are likely several fruits and vegetables in violation. Its a short, generic, common word. Its has an "i" infront of it, but otherwise, its a very difficult name to defend.
You would think they would be aware of this fact, since "Macintosh" is a specific type of Apple (the fruit).
There is nothing exotic or magical about "hearing" or "knowing" a TV is turned on. Although, high frequency hearing abilities vary among the public.
NTSC television uses a 15KHz horizontal frequency that audiably generates a 15KHz tone. The pitch is so high that most people really hear it like you would a baby crying, but they just sense it as being there. To me, televisions sound similar to ringing in the ears. High audio frequencies are very directional, and thats why you can always seek out the source.
Capacitors can also audibly resonate. When I was a kid, I used to build circuits with a little radioshack breadboard. One of the circuit projects consisted of making a cap buzz -- its very simple to do, especially on accident. Given the construction quality and engineering of cheap electronics these days, a buzzing cap wouldnt be too surprising.
Never expiring password? Backdoor into every corporate network? I work at a public company as a network engineer, and there is no such thing. We couldn't get away with it, even if we wanted to. There is this thing called Sarbanes Oxley....and yeah, they kind of frown on passwords that never expire and role based accounts. Plus its just dumb when you can always change the password on a network device or server. Its not like the enable password on a Cisco device is burned into ROM with a cattle prod.
We also implement individual user accounts wherever possible. Role based accounts are avoided, unless the device simply has no way to handle AAA.
If someone out there has a password that never expires and cannot be changed, you have a serious design problem. No real company I have worked at has done business this way. And while I am certain that there has to be some truth to this alarmist generalization, I am really am having a hard time figuring out who this would be.
Your EE friend is not the only one, all of our future data center build outs will be 208VAC. We are simply running too many amps at 110VAC for it to make sense for us anymore. Just about any piece of equipment will run at 208VAC these days -- every power supply seems to be internationalized, it is probably cheaper this way.
Another serious issue threatening coastal communities is coastal errosion. Over the past years, during the summers, the ice cap has retracted at quite an alarming rate -- ask anyone who lives up there.
It becomes quite windy at times, and all this (newly) open water picks up very large waves. There have been several instances were storms have jumped these errosion barriers and flooded these communities.
This is met with an assault of machinery (cats, dumptrucks, etc) during some of the wilder storms to keep these barriers in place, but I don't know how long this tactic will keep up.
Other coastal communities are not as lucky as Barrow, and have been forced to relocation.
People may joke that "..the melting of the Arctic ice cap would be annoying to several dozen polar bears..", but an entire culture calls this area home.
It will be very sad to have to tell stories to my children/grand children about what used to be.
Instead of taking apart a GSM cell phone, check out some of the (low cost) GSM modules instead.
Sparkfun.com sells an OEM GSM module kit for $229 which contains antenna, module, PCB, camera, and USB interface. This OEM module, a Telit GM862, has full GSM and GRPS functionality, including audio and camera phone functions. You could easily adapt it to an astrisk system.
I purchased one of these kits a while back, and you have enough functionality to create your own home-brew cellular phone.
As a Cisco network engineer, we have a similar problem. Although, we do own all the network gear at least. We have no control over the clients. Here is a way you can enforce your policies on a system you cannot install anti-virus software onto.
While expensive anomially based and signature based products do exist, as well as open source applications, you can simply look for one general worm characteristic: large ARP storms. Nearly all worms will attempt to contact a large amount systems with haste, generally above the 15-25 ARP/sec thesholds.
Pipe a simple tethereal arp filter into a perl script. You can measure these rates on a per host basis. After automatically identifying culprits, disable the ethernet ports using an expect script or perhaps the Cisco Perl module if you are running Cisco switches.
Now, this is only useful if you are able to access these switches or convince another party to grant you this.
If you dont even have access to switches, another option is to grant only very short DHCP leases and run a similar script above. For violators, either ignore their dhcp requests, or offer them a lease to some blackhole network that is unreachable.
With either solution, people will complain that they are not able to gain network access. Offer to clean their machines, and put them back on the network. If they continue to behave badly, the punishment will repeat.
While we have long since invested in anomally-based detection systems due to worms, we once had to use the tethereal script for some of the first dcom worms. It was a life saver/network saver.
I have noticed that a lot of cellular carriers tend to completely ignore and indefinately cache DNS entries. This sucks for a company like mine.
About 6 months ago we were switching a wireless application back end from one datacenter to another. I set several records to a very low TTL (15 minutes) about three months before -- just to be safe.
The application completely broke on one particular carrier -- it was still resolving to the old IP. Every other DNS server in the world picked it up but theirs.
It required a direct phone call to several network engineers to correct the problem. Given their clueless responses and complete misunderstanding of how DNS even works, I suspected it was a misconfiguration of their caches.
How did they fix it? They just rebooted the nameserver to clear the DNS cache! How crafty.
Oh how I can't wait to work with this carrier again!

While Voom technically had the most HDTV channels, it is a far stretch to call it real content. There is just not enough real content out there to show this many channels in HDTV.
