I occasionally use Upwork (formerly eLance) to hire contract workers in other countries to work on some projects. Considering that I live in the San Francisco Bay Area, which happens to be one of the most expensive places to live, I have to constantly remind myself to price my projects according to the economy and cost-of-living where I hire workers overseas. Here’s an example cost analysis.
Let’s say that, based on the type of work you need done, a fair US wage would be $10 per hour. Let’s also say that you expect the work should be done in no more than 17.5 hours. Therefore, the total project cost in the US would be $175.
Let’s say you hire someone in Egypt to do the work. You’ll need a way to fairly and reasonably convert wages in the US to wages in Egypt. One way to do this is by comparing each countries GPD per capita, which is an estimate of the average salary in a particular country.
GDP Per Capita
According to the World Bank, as of July 6, 2018, the GDP per capitas of the US and Egypt are:
In other words, the average annual salary in the US and Egypt are $60k and $3K, respectively. Read More

Do the following before going to sleep at night:
1. Salycilic Acid
Wash and clean your entire face using salycilic acid.
Clearasil Rapid Rescue Deep Treatment Wash 6.78oz – $6.00
2. Skin Moisturizer
Apply skin moisturizer to your entire face. This is necessary because the next step using benzoyl peroxide will make your skin red and very dry. The moisturizer will help prevent redness and dryness and will only slightly limit the effectiveness of the benzoyl peroxide.
Up&up Daily Moisturizing Lotion – $2.00
3. Benzoyl Peroxide (BP) 10%
Apply a thin layer of 10% benzoyl peroxide (BP) to entire face. Don’t go out in the sun with BP without sunscreen as sunlight hitting the BP could darken your skin. Don’t get BP on your eyes and hair. BP has a bleaching side effect and can cause dark fabric, e.g. towels and clothes, to appear bleached. BP is considered the best OTC (over the counter) acne medicine.
Max. Strength 10% Benzoyl Peroxide Gel Acne Medication – 1oz – Up&Up – $3.50
Put a pillow cover, ideally one that is benzoyl peroxide resistant, over your pillow.

Here’s what you see in the Chrome console.
The first console.log statement is showing the final value of the object as opposed to the value at the time the console.log statement was called. That’s because console.log is displaying a reference to the object, not the copy of the object at the time the console.log statement was called. To solve this, always stringify (serialize) the object which makes a deep copy (deep clone) of it before consoling it out. To see a prettified display of the object, parse the stringified object. This is what’s done in the 2nd console.log statement which shows the expected value of the object.

When you buy new car tires, you’ll either go online and enter your car’s year, make, model, and trim or give that information to someone at a store. Unfortunately, the tire specifications you get in response will not necessarily be correct. For the past 13 years, I’ve been buying car tires for my 2003 Honda Accord DX and the tire specs I’d be given are
This information was taken from tires.costco.com and from the tire specialist’s computer at a Costco Tire Center. It says that my tire size is P215/60R17. The tire specs in the driver side door, however, says this:
It says that my tire size should be P205/65R15. While it may be okay to go with a slightly different size, it’s probably better to go with the manufacturer’s recommendation. Read More

If you have nasal congestion, which could also cause coughing, then one of the best medicines to take is Sudafed. However, be careful which one you get.
Sudafed (behind the counter)
This kind of Sudafed has the active ingredient Pseudeophedrine which can be used to illegally make methamphetamine (meth / “speed”). As such, it can only be gotten behind the counter, i.e. by talking to a pharmacist at Walgreens. You can get 4 hour Sudafed and 12 hour Sudafed. If you are impatient and can’t wait 12 hours to take the 12-hour version, then just buy the 4-hour version. Psychologically, taking medicine more often may make you feel better. One doctor told me that this version of Sudafed (Pseudeophedrine) is better than the kind below (Sudafed PE). Also, you can get a cheaper generic brand like Wal-Phed since all that really matters is the active ingredient, not the brand.
Sudafed PE (over the counter)
This kind of Sudafed can be gotten over the counter (on a shelf) because it’s active ingredient is phenylephrine which can’t be used to make illegal drugs. That’s why it has the PE acronym in the name.

In the US, car tire tread depth is measured in 32nds of an inch. New tires typically come with 10/32” or 11/32” tread depths, and some truck, SUV and winter tires may have deeper tread depths than other models. A tire is legally worn-out if the tread depth is 2/32nds. Therefore, a typical tire that starts with 10/32″ of original tread depth has only 8/32″ of usable tread depth. A tire that started with 10/32″ of original tread depth and has worn off 4/32″ (down to 6/32″ of remaining tread depth) is 50% worn. Though 2/32nds of tread depth is the legal minimum, you should change your tires when they reach 4/32nds of tread depth. At tread depths less than 4/32nds, you may experience hydroplaning when driving in the rain and lose control of your vehicle.
Tread Depth Gauge
There are manual and digital tread depth gauges. I’d go with a manual one so you don’t have to worry about replacing a battery.

When looking to buy a battery charger or power adapter for a device such as a phone or laptop, you may be unsure whether the one you buy will be sufficient or even blow up your device. Here are basic guidelines to keep in mind.

There will always come a time when you wish the noise outside your room in your home could go away and that the sound that you are making, e.g. from playing music to watching a movie, could not be heard by people in other rooms. There is a unit of measure called STC (Sound Transmission Control) that indicates how much of a sound can penetrate a wall. According to Wikipedia, here are common levels.
|STC||What can be heard|
|25||Normal speech can be understood quite easily and distinctly through wall|
|30||Loud speech can be understood fairly well, normal speech heard but not understood|
|35||Loud speech audible but not intelligible|
|40||Onset of “privacy”|
|42||Loud speech audible as a murmur|
|45||Loud speech not audible; 90% of statistical population not annoyed|
|50||Very loud sounds such as musical instruments or a stereo can be faintly heard; 99% of population not annoyed.|
|60+||Good soundproofing; most sounds do not disturb neighbouring residents.|
and here are different STC values by partition (wall) type.
|27||Single pane glass window (typical value) (Dual pane glass window range is 26-32)|
|33||Single layer of 1/2″ drywall on each side, wood studs, no insulation (typical interior wall)|
|39||Single layer of 1/2″ drywall on each side, wood studs, fiberglass insulation|
|44||4″ Hollow CMU (Concrete Masonry Unit)|
|45||Double layer of 1/2″ drywall on each side, wood studs, batt insulation in wall|
|46||Single layer of 1/2″ drywall, glued to 6″ lightweight concrete block wall, painted both sides|
|46||6″ Hollow CMU (Concrete Masonry Unit)|
|48||8″ Hollow CMU (Concrete Masonry Unit)|
|50||10″ Hollow CMU (Concrete Masonry Unit)|
|52||8″ Hollow CMU (Concrete Masonry Unit) with 2″ Z-Bars and 1/2″ Drywall on each side|
|54||Single layer of 1/2″ drywall, glued to 8″ dense concrete block wall, painted both sides|
|54||8″ Hollow CMU (Concrete Masonry Unit) with 1 1/2″ Wood Furring, 1 1/2″ Fiberglass Insulation and 1/2″ Drywall on each side|
|55||Double layer of 1/2″ drywall on each side, on staggered wood stud wall, batt insulation in wall|
|59||Double layer of 1/2″ drywall on each side, on wood stud wall, resilient channels on one side, batt insulation|
|63||Double layer of 1/2″ drywall on each side, on double wood/metal stud walls (spaced 1″ apart), double batt insulation|
|64||8″ Hollow CMU (Concrete Masonry Unit) with 3″ Steel Studs, Fiberglass Insulation and 1/2″ Drywall on each side|
|72||8″ concrete block wall, painted, with 1/2″ drywall on independent steel stud walls, each side, insulation in cavities|
Note that a typical interior wall has an STC value of 33.
Some options for increasing the STC value in your walls:
