10 Tips for Using Less Gas and Saving More Money
By
Danek Kaus

The hurricane that has devastated so many lives has created a huge spike in gasoline prices around the country, even in areas that are not directly affected by the crisis.

With this in mind, here are some ways that you can reduce your gas consumption, and thereby spend less money at the pump. At the same time, you’ll also be helping the environment by putting fewer emissions into the air.

1. Avoid idling as much as possible. Modern engines do not need to be warmed up. In fact, they warm up better by driving them slowly, under a light load. Instead of using the drive-up window at the local fast food joint, consider going inside instead. If you do use the pick-up window, turn off the engine while you are in line. It takes less gas to restart a warmed-up engine than it does to idle for 30 seconds or more.

2. Accelerate and decelerate slowly. Don’t stomp on the gas peddle when the light turns green. Try to anticipate traffic flow and drive accordingly, keeping safety in mind at all times.

3. Lighten the load. If you have a bunch of stuff in your car that you don’t need with you, store it somewhere else. The more your car weighs, the more gas the engine must burn.

4. Combine trips. Try to run all your errands at one time. Planning ahead for what you need to buy and do can save a lot of trips and miles.

5. Check tire pressure. Improperly inflated tires create drag and reduce fuel efficiency by as much as 2%. Properly inflated are safer and they last longer.

6. Use the right gas. Check your owner’s manual for the right grade of gas for your car. It is a waste of money to use a higher grade then recommended.

7. Close the gas cap properly. Make sure the seal is tight. If you buy a replacement cap, make sure it is the right one for your make and model.

8. Change the air filter regularly. A clogged filter reduces mileage.

9. Change the spark plugs. Make sure to install new ones at the appropriate intervals to improve mileage.

10. Drive a fuel-efficient vehicle. If you have more than one vehicle, drive the one with the best mileage rating whenever possible.


I would like to close by asking everyone who reads this article to please give whatever you can to relief agencies such as The Red Cross and The Salvation Army, or one of many other worthy organizations that are working hard to bring aid and comfort to the victims of Hurricane Katrina.

Although it hurts to pay more at the pump, it can’t compare with the agony that so many in the Gulf Coast are enduring.

Thank you.

11 advanced MySQL questions

Author: bussiness // Category:
  1. Explain MySQL architecture. - The front layer takes care of network connections and security authentications, the middle layer does the SQL query parsing, and then the query is handled off to the storage engine. A storage engine could be either a default one supplied with MySQL (MyISAM) or a commercial one supplied by a third-party vendor (ScaleDB, InnoDB, etc.)
  2. Explain MySQL locks. - Table-level locks allow the user to lock the entire table, page-level locks allow locking of certain portions of the tables (those portions are referred to as tables), row-level locks are the most granular and allow locking of specific rows.
  3. Explain multi-version concurrency control in MySQL. - Each row has two additional columns associated with it - creation time and deletion time, but instead of storing timestamps, MySQL stores version numbers.
  4. What are MySQL transactions? - A set of instructions/queries that should be executed or rolled back as a single atomic unit.
  5. What’s ACID? - Automicity - transactions are atomic and should be treated as one in case of rollback. Consistency - the database should be in consistent state between multiple states in transaction. Isolation - no other queries can access the data modified by a running transaction. Durability - system crashes should not lose the data.
  6. Which storage engines support transactions in MySQL? - Berkeley DB and InnoDB.
  7. How do you convert to a different table type? - ALTER TABLE customers TYPE = InnoDB
  8. How do you index just the first four bytes of the column? - ALTER TABLE customers ADD INDEX (business_name(4))
  9. What’s the difference between PRIMARY KEY and UNIQUE in MyISAM? - PRIMARY KEY cannot be null, so essentially PRIMARY KEY is equivalent to UNIQUE NOT NULL.
  10. How do you prevent MySQL from caching a query? - SELECT SQL_NO_CACHE …
  11. What’s the difference between query_cache_type 1 and 2? - The second one is on-demand and can be retrieved via SELECT SQL_CACHE … If you’re worried about the SQL portability to other servers, you can use SELECT /* SQL_CACHE */ id FROM … - MySQL will interpret the code inside comments, while other servers will ignore it.
