Concrete That Purifies the Air 88

fergus07 writes "Although much of the focus of pollution from automobiles centers on carbon emissions, there are other airborne nasties spewing from the tailpipes of fossil fuel-powered vehicles. These include nitrogen oxides (NOx). In the form of nitrogen dioxide it reacts with chemicals produced by sunlight to form nitric acid – a major constituent of acid rain – and also reacts with sunlight, leading to the formation of ozone and smog. Everyone is exposed to small amounts of nitrogen oxides in ambient air, but exposure to higher amounts, in areas of heavy traffic for example, can damage respiratory airways. Testing has shown that surfacing roads with air purifying concrete could make a big contribution to local air purity by reducing the concentration of nitrogen oxides by 25 to 45 percent."

When Rewriting an App Actually Makes Sense 289

vlangber writes "Joel Spolsky wrote a famous blog post back in 2000 called 'Things You Should Never Do, Part I,' where he wrote the following: '[T]he single worst strategic mistake that any software company can make: They decided to rewrite the code from scratch.' Here is a story about a software company that decided to rewrite their application from scratch, and their experiences from that process."

Actually, it can. There is such a thing as backlash. The pressure to change the meaning of a word that has so much history for the religious has created an environment where people who were neutral in the past have become polarized against gay marriage. When the MA courts forced gay marriage upon the people there, they created a groundswell of resistance that has lead to 40 states enacting bans on gay marriage. Many prominent gays have stated that pushing too fast for gay marriage has set the movement back at least 20 years. I believe this to be true.

"yet if this were a law revoking the right ..." Funny that the "right" that is being "revoked" was entirely the creation of 4 judges who overturned an existing law banning recognition of gay marriages. Those same 4 judges then created the entire mess of people thrown into limbo over the status of their "marriages" when the court refused to stay their ruling until after the election. Remember that Prop. 8 was already on the ballot when they overturned the existing law. Also, the state allowed the proposition to go forth as a standard proposition requiring 50% when they certified it for the ballot. It was only after they lost that the idea that it was a rewrite came up. Sounds to me like playing the game, losing, then demanding that the rules be changed retroactively to benefit themselves.

Or thrown out. The people of California have voted repeatedly that gay marriage is a none starter. It can be argued that the incessant screaming for "equal rights" has done more harm to the gay agenda than not. 30 states have passed and implemented laws banning gay marriage. These laws were a response to the Mass. courts imposing gay marriage on the people there. The fact is that everywhere that anti-gay marriage laws have made it to the ballot, the measure has passed and been implemented. If the CA supreme court overturns this amendment, I would expect to see a new amendment which would allow CA citizens to through out those same supreme court justices.

1. Use the military to assist the border patrol. Anyone crossing the border illegally would be given 10 lashes with a cane and deported. Same with people found to be in the country illegally after a 90 grace period.

2. Prosecute all employers who are hiring illegals. Arizona's law sounds good.

3. Give all recipients of welfare a physical. If they are physically capable of working, take them out of the welfare system after 6 months and require a 2 year delay before they can be re-enrolled.

4. Stop all the nanny state financial giveaways that make it more lucrative to be getting a government handout than it is to work.

5. Use the suddenly available labor pool to take over the jobs vacated by all the illegals self-deporting after #1 goes into effect.

6. Make all prison sentences "at hard labor". Chain gangs and work parties to do most of the public works jobs.

7. Cut the number of people on government pay role by at least 50% by using prisoners to do most manual labor jobs currently being done by unionized civil servants.

8. Revisit all the laws currently on the books and eliminate any that have no basis in common sense and the constitution. Re-write remaining laws in plain language that do not require an education in Latin to understand.

9. Implement term limits that limit politicians to 6 years max and then forbid that person from receiving a government pay check for at least 6 years before being able to run for office again.

10. Eliminate the IRS. Institute a 3% sales tax on all sales and services. This should be more than enough income to support the remaining government functions.

11. Implement a law that requires all bills in Congress and the Senate to be single subject. No more Omnibus bills with thousands of set asides. All amendments must be read and debated on the floor. A filibuster would only last as long as the politician could continue talking ABOUT THAT SUBJECT.

12. Implement a 5 year limit on appeals for the death penalty. Using hanging or firing squad as the method. Televise on all stations in the region where the person is being executed.

13. Limit frivolous lawsuits by making the person filing pay the court costs and lawyer fees if they loose.
