Hulu vs Netflix

Among the online streaming options available today, Netflix and Hulu are two of the most popular but the focus of their content library is quite different. Netflix offers the widest selection of movies and thousands of older TV shows, while Hulu Plus, offers a stronger collection of current-season TV shows and a smaller selection of movies. One disadvantage with Hulu Plus is ads — Netflix offers an ad-free experience. Both services are $7.99 per month and both have apps available on a wide variety of devices, including smart TVs.

Content Library

TV Shows vs. Movies

Hulu offers some movies but is primarily known for TV shows, including related clips, trailers and interviews. It is unique in that it has episodes available quickly, often within a day of the original airing, and features shows from networks including NBC, ABC, Fox, Current TV, ION Television, USA Network, Brave, Syfy, E!, A&E, and Oxygen. Hulu has made four original series – A Day in the Life, Battleground, Spoilers and Up to Speed – and is launching 3 more.

Netflix has many more films and TV shows, but it can often be a year after an episode airs before it appears on the service. However, it has a huge library of older shows, and a large children’s section. Netflix is also working on its own original shows, and has launched House of Cards and the revival of (or sequel to) Arrested Development.

EDITSize

Hulu has not stated the size of its library, but it is estimated that it has more than 43,000 TV episodes from 1,650shows, and over 2,500 films.

Netflix has over 100,000 titles in its library. This counts individual episodes of TV shows. Netflix does not publicize the size of its content library because, the company says, it changes as title availabilities expire or new ones become available.

EDITForeign

Hulu offers some international TV shows, typically from the UK and Canada. It also has Korean drama like Boys Before Flowers.

Netflix offers many foreign films, and some foreign TV series, including Norwegian drama Lilyhammer, and Britishshows such as Being Human and Downton Abbey.

EDITDevice Compatibility

The Hulu website is incompatible with most portable devices, such as iPads, because it uses Flash. Hulu Plus members can use it on many platforms, including Apple TV, iPad, Blu-ray players, TiVo, iOS and Android smartphones, Wii, Nintendo 3DS, PlayStation 3, and Xbox 360.

Netflix apps are also available on all these platforms and others such as Roku and Windows phone.

See devices supported by Hulu and devices supported by Netflix (Super HD).

EDITClosed Caption Availability

82% of Netflix content has subtitles. The company aims to reach 90% availability by the end of 2013 and 100% by the end of 2014.

EDITWhere Offered

Hulu is only available in the US and in Japan.

Netflix is available in many countries, including the US, Canada, Mexico, South America, the UK, Ireland, and Nordic countries (excluding Iceland). The available content varies depending on the region.

EDITPopularity

As of April 2013, Hulu Plus has about 3 million subscribers and Netflix has over 30 million subscribers in the US.

EDITPrice

Basic use of Hulu is free, as it is supported by ads. Hulu Plus costs $7.99. This allows users to download mobileapps and access more content, but is still supported by ads.

Netflix costs $7.99 per month, for unlimited instant streaming.

EDITHow to choose between Netflix and Hulu Plus

The bottom line is that if you're into movies, Netflix is a better option and if you like to stay current on all the latest TV shows, Hulu Plus is a better option. Of course, when comparing with cable, it is cheaper to get both Hulu Plus and Netflix ($16 per month compared with cable TV, which typically runs from $30 - $120 per month).

CT Scan vs MRI

A CT Scan (or CAT Scan) and an MRI operate differently and are better suited for different types of diagnoses. An MRI suited for examining soft tissue, (e.g. ligament and tendon injury, spinal cord injury, brain tumors etc.) while a CT scan is better suited for bone injuries, lung and chest imaging, and detecting cancers. CT scans are widely used in emergency rooms because the procedure takes less than 5 minutes. An MRI, on the other hand, can take up to 30 minutes.

An MRI typically costs more than a CT scan. One advantage of an MRI is that it does not use radiation while CAT scans do. This radiation is harmful if there is repeated exposure.

Improve this chart	CT Scan	MRI
Cost:	CT Scan costs range from $1,200 to $3,200; they usually cost less than MRIs (about half the price of MRI).	MRI costs range from $1200 to $4000 (with contrast); which is usually more than CT scans and X-rays, and most examining methods.
Time taken for complete scan:	Usually completed within 5 minutes. Actual scan time usually less than 30 seconds. Therefore, CT is less sensitive to patient movement than MRI.	Scanning typically run for about 30 minutes.
Radiation exposure:	The effective radiation dose from CT ranges from 2 to 10 mSv, which is about the same as the average person receives from backgroundradiation in 3 to 5 years. Usually, CT is not recommended for pregnant women or children unless absolutely necessary.	None. MRI machine control/limit energy deposition in patient
Ability to change the imaging plane without movingthe patient:	With capability of MDCT, isotropic imaging is possible. After helical scan with Multiplanar Reformation function, an operator can construct any plane.	MRI machines can produce images in any plane. Plus, 3D isotropic imaging also can also produce Multiplanar Reformation.
Effects on the body:	Despite being small, CT can pose the risk of irradiation. Painless, noninvasive.	No biological hazards have been reported with the use of the MRI.
Scope of application:	CT can outline bone inside the body very accurately.	MRI is more versatile than the X-Ray and is used to examine a large variety of medical conditions.
Application:	Suited for bone injuries, Lung and Chest imaging, cancer detection. Widely used in Emergency Room patient.	Suited for Soft tissue evaluation, e.g. ligament and tendon injury, spinal cord injury, brain tumors etc.
Details of bony structures:	Provides good details about bony structures	Less detailed compared to X-ray
Acronym for:	Computed (Axial) Tomography	Magnetic Resonance Imaging
Details of soft tissues:	A major advantage of CT is that it is able to image bone, soft tissue and blood vessels all at the same time.	Much higher soft tissue detail as compare to CT scan.
Principle used for imaging:	Uses X-rays for imaging	Uses large external field, RF pulse and 3 different gradient fields
History:	The first commercially viable CT scanner was invented by Sir Godfrey Hounsfield in Hayes, United Kingdom; the first patient brain-scan was done on 1 October 1971.	First commercial MRI in 1981, with significant increase in MRI resolution and choice of imaging sequences over time.
Principle:	X-ray attenuation was detected by detector & DAS system, follow by math. model (back projection model) to calculate the value of pixelism then become a image.	Body tissue that contains hydrogen atoms (e.g. in water) is made to emit a radio signal which is detected by the scanner. Search for "magnetic resonance" for physics details.
Image specifics:	Good soft tissue differentiation especially with intravenous contrast. Higher imaging resolution and less motion artifact due to fast imaging speed.	Demonstrates subtle differences between the different kinds of soft tissues.
Limitation for Scanning patients:	Patients with any Metal implants can get CT scan. A person who is very large (e.g. over 450 lb) may not fit into the opening of a conventional CT scanner or may be over the weight limit for the moving table.	Patients with Cardiac Pacemakers,tattoos and metal implants are contraindicated due to possible injury to patient or image distortion (artifact). Patient over 350 lb maybe over table weight limit. Any ferromagnetic object may cause trauma/burns.
Intravenous Contrast Agent:	Non-ionic iodinated agent is covalently bind the iodine and have fewer side effects. Allergic reaction is rare but more common than MRI contrast.

How the scans work

EDITHow MRIs work

Using a very powerful magnet and pulsing radio waves the detection coils in the MRI scanner read the energyproduced by water molecules as they re-align themselves after each RF alignment pulse. The collected data is reconstructed into a two-dimensional illustration through any axis of the body. Bones are virtually void of water and therefore do not generate any image data. This leaves a black area in the images. MRI scanners are best suited for imaging soft tissue.

The CT scan of a person's torso.

EDITHow a CT Scan works

CT, Computerized Axial Tomography, uses xrays to generate images of the body, including bone. In the CT scanner the x-ray tube, (source) rotates around the patient laying on the table. On the opposite side of the patient from the tube is the x-ray detector. This detector recieves the beam that makes it through the patient. The beam is sampled via some 764 channels, (approximate number of channels). The signal received by each channel is digitized to a 16 bit value and sent to the reconstruction processor. Measurements are taken about 1000 times per second. Scan rotations are usually 1 to 2 seconds long. Each view/channel chunk of scan data is compared to calibration scan data of air, water and polyethelyne, (soft plastic) previously acquired in the exact same relative location. The comparisons allow the image pixels to have a known value for a particular substance in the body regardless of differences in patient size and exposure factors. The more samples, or views, the better the picture.

The following video explains how the different types of scans work — Ultrasound, CT scan, MRI and PET scan.

EDITPros and Cons

In the following ABC News video, Paul Christo, M.D. at Johns Hopkins explains the use of MRI or CT scans for diagnosing problems related to the spine.

EDITAdvantages of MRI over CAT Scan

• A CAT scan uses X rays to build up a picture. MRI uses a magnetic field to do the same and has no known side effects related to radiation exposure.
• MRI has much higher detail in the soft tissues.
• One of the greatest advantages of MRI is the ability to change the contrast of the images. Small changes in the radio waves and the magnetic fields can completely change the contrast of the image. Different contrast settings will highlight different types of tissue
• Another advantage of MRI is the ability to change the imaging plane without moving the patient. Most MRI machines can produce images in any plane.
• Contrast agents are also used in MRI but they are not made of iodine. There are fewer documented cases of reactions to MRI contrast and it is considered to be safer than X-ray dye.
• For purposes of tumor detection and identification, MRI is generally superior. However, CT usually is more widely available, faster, much less expensive, and may be less likely to require the person to be sedated or anesthetized.
• CT may be enhanced by use of contrast agents containing elements of a higher atomic number than the surrounding flesh (iodine, barium). Contrast agents for MRI are those which have paramagnetic properties. One example is gadolinium. Iodine use may be associated with allergic reactions.

EDITAdvantages of CT Scan over MRI

• CT is very good for imaging bone structures.
• Some patients who have received certain types of surgical clips, metallic fragments, cardiac monitors or pacemakers cannot receive an MRI.
• The time taken for total testing is shorter than taken by MRI
• MRI cannot be done in patients who are claustrophobic as the patient has to remain inside the noisy machine for about 20-45 minutes
• It is cheaper than an MRI. A CT scan costs $1,200 to $3,200 while an MRI can cost up to $4,000.

EDITCost of Machines

Not surprisingly, there are various CT scanners available and there is a large variation in price depending upon the features and brand. This is a good pricing guide for CT scan machines. A vanilla 4-slice CT scanner costs $85,000 to $150,000. A 16-slice scanner costs $145,000 to $225,000 and the top-of-the-line 64-slice CTs can cost up to $450,000. The machines also typically need annual maintenance, which can also cost tens of thousands of dollars.

MRI machines are available in 1.5 T and 3 T (T stands for Tesla) models. 3T models are more expensive but offer higher image quality and shorter scanning times. 1.5 T MRI scanners start at around $1 million and 3T models are 50% more expensive. Manufacturers may include accessories in their quote, which include a workstation to view images, contrast injectors, This is a good guide for MRI scanners.

Cat5e vs Cat6

Cat6 cables, also called Category 6 or Cat6 cables, provide lower crosstalk, a higher signal-to-noise ratio, and are suitable for 10GBASE-T (10-Gigabit Ethernet), while Cat5e cables support only up to 1000BASE-T (Gigabit Ethernet). As a means of future-proofing your network, Cat6 is generally a better choice and worth the small premium in price. Cat5e and Cat6 cables are both backwards compatible, which means newer Cat6 cables can be used with older Cat5e, Cat5 and even Cat3 equipment.

Wiring

Both Cat5e and Cat6 are twisted pair cables that use copper wires, typically 4 twisted pairs in each cable. The specification for Cat6 features more stringent specifications for crosstalk and system noise, and provides performance of up to 250 MHz. Cat5e, in contrast, performs up to 100 MHz. This was often achieved using a spline (a longitudinal separator) in the wiring, which isolates each of the four pairs of twisted wire. However, this made Cat6cables more rigid; newer cables use other methods to reduce noise and are more flexible. Regardless of whether a spline is used, a cable that meets Cat6 specifications provides significantly lower interference or near end crosstalk (NEXT) in the transmission. It also improves equal level far end crosstalk (ELFEXT), return loss and insertion loss compared with Cat5e. The result is less noise, fewer errors and higher data rates in the transmission of the signal.

How to identify

The category is almost always printed on ethernet cables. It is not possible to identify cable categories by color, butCat6 cables are often thicker than Cat5e because it uses thicker copper wires.

EDITMaximum Length

Both Cat5e and Cat6 cable specifications allow lengths up to 100 meters, but Cat6e has a lower max length (55 meters) when used for 10GBASE-T (10 Gigabit Ethernet). In order to run 10GBASE-T for 100 meters, Category 6acable, or Augmented Category 6, cables need to be used. Cat6a cables allow performance up to 500 MHz.

If network infrastructure requires covering distances larger than 100 meters, repeaters or switches are required to amplify the signal.

EDITSpeed

As mentioned previously, Cat6 cables can be used to power 10GBASE-T, or 10 Gigabit Ethernet, while the maximum that Cat5e cables can support is 1GBASE-T, or 1 Gigabit Ethernet. This is because Cat6 cables performup to 250 MHz, more than twice that of Cat5e cables (100 MHz).

EDITCost

The price of ethernet cables vary by length, manufacturer and seller. In general, Cat6 cables are 10-20% more expensive compared with Cat5e cables. However, cables are generally cheap and the speed boost offered by Cat6 cables usually makes the price premium well worth it, even for home use.

EDITWhat and where to buy

Cat5e cables seem to be more popular on Amazon.com. Only 2 of the top 20 best selling ethernet cables on Amazon are Cat6.
