Facebook’s Balancing Act: The Good, the Bad, and the Ugly

Facebook’s Balancing Act: The Good, the Bad, and the Ugly

The good news: Facebook (NASDAQ: FB  ) turned fabulously profitable in the just-reported second quarter thanks to a redesigned ad flow on mobile Facebook apps. Revenues jumped 23% from the first quarter to the second. Last year, the same comparison yielded just an 11% seasonal gain. The year-ago quarter’s net loss turned into a tidy profit.

In response, share prices jumped more than 30% overnight and sit very close to all-time highs that were set during the stock’s IPO.

The bad news: The ad assault is interfering with the user experience. A fresh survey (free registration required) from the American Customer Satisfaction Index shows Facebook dead last among online media sites in terms of user satisfaction. “Facebook users find the numerous changes to the site’s interface taxing,” says the ACSI. Twenty-seven percent of users surveyed complained that ads are ruining their Facebook experience these days.

The ugly news: The good news may not last very long. Facebook had better dial back the ad blitz if it wants those disgruntled users to stick around.

It’s a high-wire balancing act between monetization and user satisfaction. Lean too far in one direction, and you won’t make any money from those billions of page views. Err too far in the other direction, and those profitable page views will melt away as unhappy users find greener pastures.

Don’t think it couldn’t happen. Facebook is not too big to fail. Unless the company strikes that crucial balance before it’s too late, we could very well see another mass exodus from one leading social network to another.

Facebook itself killed MySpace by launching a better service in the same genre. Before that, MySpace trampled all over social pioneer Friendster in much the same way.

And there are Facebook alternatives waiting to crush the current king at the first opportunity, believe it or not.

Chief among these is Google (NASDAQ: GOOG  ) and its Google+ service, which benefits from tight integration with the world’s most popular search engine as well as with leading video site YouTube.

Twitter sings a somewhat different tune but can fill many of the functions of a Facebook account. LinkedIn (NYSE: LNKD  ) is basically Facebook for corporate users and could very well expand into the consumer side of things if it wanted to.

All of these alternatives offer fewer ads and a cleaner experience than Facebook. LinkedIn ties with Facebook at the least satisfied end of the ACSI survey; everyone else runs miles ahead. Yes, even the much-maligned Google+ “ghost town.” And even LinkedIn reports fewer ad-taint complaints than Facebook.

That’s why I’d take this week’s Facebook share-price pop as a temporary boost, and not as a sustainable clean bill of health. The service currently leans far too heavy on the monetization side of the fence and runs a very real risk of finding out that the next era of social networking doesn’t include much Facebooking.

So my bearish CAPScall on Facebook stays in place until Mark Zuckerberg and company adjust their strategy again. If you can’t keep your users happy, the money will very quickly cease to matter.

Watch our jaw-dropping investor alert video today to find out why The Motley Fool’s chief technology officer is putting $117,238 of his own money on the table, and why he’s so confident this will be a huge winner in 2013 and beyond.

Monoprice 27″ IPS-G Pro LED Monitor WQHD 2560×1440

Monoprice 27″ IPS-G Pro LED Monitor WQHD 2560×1440

Monoprice is among the more interesting companies you probably haven’t heard of. Started out of an apartment around a decade ago, the company initially sold everything at a single price, hence the name. That business model may have worked when the product line was mostly cables and connectors, but the company now offers a diverse array that includes monitors (more in a moment), home theatre screens, graphics tablets, headphones, apocket-size pico projector, an action cam, even electric guitars – and, yes, cables, connectors and accessories as well. It’s a lineup with no seeming rhyme or reason, other than quality products at bargain prices.

And that actually is the rhyme and reason behind Monoprice products. According to CEO Ajay Kumar, the company looks for categories where vastly overpriced products predominate. That gives Monoprice room to create and sell products at dramatically lower price points, while still maintaining strong profit margins.
“We are in the right place at the right time with our business model,” says Kumar, who joined the company in July 2011. “We offer the same cable or accessory as national retail brands, but for much less cost. However, we are not cutting corners as we employ high-quality manufacturing partners who work with our specs. Our markup is much lower and we pass those savings to our customers. Monoprice brings them a value proposition they can’t find anywhere else.”
And that leads us to the Monoprice 27″ IPS-G Pro LED Monitor WQHD 2560×1440 Product ID 10489, which is what you came here for. I’ve been rocking this 16:9 (widescreen) monitor for over a month now and it’s stunning. Let’s take a look at the stats and find out why.
Start with the size, 27″. You don’t have to join Grindr to know that size matters. A larger screen means that you can work easily with more windows at once. It makes copying files and editing text and spreadsheets easier and obviously makes working with pictures and video more convenient, if that’s your thing. And if you’re a gamer, a large screen is essential. Ditto if you are, for instance, a daytrader or a designer.
Hand in glove with size is resolution. “WQHD” may sound like a Minneapolis TV station, but it means 2560 x 1440 pixels. Some 27″ screens max out at regular Full HD, which is 1920 x 1080. The higher resolution of the Monoprice unit means that more detail is visible, if your PC’s graphics card supports it. If not, you’ll be limited to 1920 x 1080 (or less, if your PC is really old). A large screen with high resolution allows you to display more information. It makes it easier to do more with your PC.
Since we’re talking graphics cards, another nice feature of the Monoprice 10489 is that it supports four different types of interface: HDMI 1.4, DVI, VGA and DisplayPort 1.2. That means that the monitor is bound to work with your existing graphics card. The package includes VGA and DVI-D cables, but these are standard length (around 6′). Because of the size of the monitor, it’s much easier to use longer cables – you can plug in the cable before maneuvering the monitor into place on your desk. Monoprice has you covered with available 15′ HDMI, DVI-D, VGA and DisplayPort 1.2 cables. Choose the one you need.
The monitor uses LEDs for the backlighting, rather than cold cathode fluorescent tubes. The benefit: more even illumination. And it uses In Plane Switching (IPS) display technology, which means you get a wide viewing angle with no color shift even when the screen is viewed at an extreme angle. Viewing angle is stated as 178 degree in both the horizontal and vertical planes.
Covering that screen is a glossy glass laminate with an antiglare coating. The antiglare coating is not a matte finish; the screen is glossy, but the antiglare coating reduces the intensity of any glare from reflected light. As with any monitor, you’ll want to position it so that ambient light is not reflected directly back at you. I’ve found the screen easy to use.
The monitor comes with a removable stand and has a 100×100 VESA mounting size for use with desk or wall mounts. The stand (which is completely removable) has rotate and tilt adjustments. It doesn’t have height adjustment, a feature found on a small number of other monitors.
The bezel is black plastic and is relatively thick. The OSD controls (brightness, etc.) are easy to reach. The connectors are in the usual awkward place for monitors, along the bottom bezel.
Several other stats are key. One is dead pixels. The monitor has over 10 million subpixels (2560 x 1440 pixels x 3 colors per pixel). If any one of those subpixels is stuck in the on or off position, you get a dead pixel – a spot that is always dark, or always white, red, reddish, green, greenish, etc. Unfortunately, dead pixels are a potential fact of life on all monitors – but Monoprice tells me they offer a zero dead pixel guarantee for a year. It’s an unusually strong guarantee, since other manufacturers often will only guarantee that the dead pixel count won’t exceed 5 or 10. The unit I received had no dead pixels.
Also important are brightness and contrast. Monoprice advertises a brightness rating of 440 cd/m², which it says is more than 15% brighter than most comparable displays, and a maximum dynamic contrast ratio of 80,000:1.
The display is indeed bright, but this is the one area where I noted a difficulty with this product – the screen is a bit too bright, even with the brightness adjustment turned down to the lowest setting. As a result, black areas on screen are rendered slightly grayish. For most people and most applications, this won’t be a problem – and it’s a phenomenon that’s scarcely unique to the Monoprice unit – but graphic designers will want to carefully compare this screen with others to see what meets their needs.
The panel features 109 pixels per inch, which translates to a 0.2331mm pixel size. The unit also includes builtin stereo speakers, which can be fed via a stereo audio cable, as well as audio from the HDMI connection. As with most builtin monitor speakers, the sound was tinny and unimpressive, so I don’t recommend using them. Buy a pair of standalone computer speakers instead.
Another stat is response time, which the company says is 6 milliseconds (gray-to-gray response time). That’s a measurement of how long it takes the monitor to change the image when the PC tells it to, and is an issue for almost no one except gamers.
Bottom line: if you’re looking for a high-quality 27″ WQHD IPS LED monitor at a great price, pick up the Monoprice 10489.

Variabel di Shell Script

Variabel di Shell Script

In the previous issue we’ve become acquainted with a shell script and managed to create a very simple shell script. If we look, we did not perform any processing on the shell script. We only show a message on the screen and execute commands on the shell through shell script. What if we want to make the program more interactive shell script?

As with any programming language, shell script also serves to recognize the variables that can hold information temporarily for a variety of purposes, for example to compute or determine the output results. You may make as much as possible or use a variable in your shell script. Name the variables are independent, large and small letters should, but make it easier to remember, make it a habit to create standard rules in the manufacture of the variable name. At this writing, all variables will be written in lowercase.

Variables can be divided into two types, namely environment variables and user variables. Environment variables are variables that have been previously determined as a part of the shell used (bash). By default, the name of this variable using all capital letters. Example of this is the $ USER variable that will contain the user name you are currently using, $ HOME home directory which contains the address of the user that is used, and so forth. To display the entire value of an existing environment variable, you can use the set command in the terminal (Figure 1). User variable is the variable name specified by the user themselves and not by the shell used.

Variables can be accessed by using the dollar sign ($) before the variable name, for example, we have a variable named “my name”, to access the value stored in the variable, we use the $ my name. To give value to a variable, we use the sign “=” is immediately followed by the value we give without any spaces, for example my name = Willy. What if the value that we want to give is a sentence? Use double quotes as the opening and closing value of a variable, such as my name = “Willy Sudiarto Raharjo”. For example, see listing 1 and try running on your computer. Seen that the value of the variable Sudiarto be regarded as a command and not part of the variable because it is not enclosed in double quotation marks. Please be careful in giving a value to a variable.

You can combine environment variables and user variables in a shell script is the same, as in listing 2. What if want to write a message using the $ character, such as “It cost me $ 15”? If we are not careful, it could be a shell script would be wrong to interpret the information that we provide and try to take the value of variable 1 (which will not contain any) and display it as a “price 5”. To fix this, use the escape character to indicate that the next character will be recognized as a regular character and not as a substitute for a variable, which marks the backslash “\” as in listing 3.

One character that needs more attention is the backtick character “` “(position number 1 on the left side your keyboard) because this character has a special function in shell programming, which is able to accommodate the output of a shell command in a variable. As an example, we will hold the result of the date command into a variable date and display its contents using the echo command as in listing 4.

To be able to receive input from the user and store it into a variable, we can use the read function is followed by the name of the variable that we want to use to store the values ​​as in Example 5 listings.

Almost Maximum Bandwidth, APJII Install Router Brocade

Almost Maximum Bandwidth, APJII Install Router Brocade

Internet users in Indonesia continues to increase. As of the end of 2012, Indonesia, which has a population of 237.5 million people has 63 million Internet users.

When compared to the condition two years ago, seen a significant surge in Internet traffic in IIX (Indonesia Internet eXchange). March 2013, the average traffic reached 10 Gigabit per second, or 4x the condition in 2010.

“As a result, our routing infrastructure that already exists is approaching maximum capacity, while Internet traffic growth shows no signs of slowing down,” said Private Harijanto (Chairman IIX).

“The main problem is about 60 percent of Indonesia’s population using mobile phones, but are accessing the Internet from the handset is still fairly small,” said Harijanto. “Obviously, this trend will change quickly. 3G infrastructure development nationwide 4G/LTE technology is almost completed and will be implemented next year. ”

Anticipating the explosion of bandwidth requirements up to 10x in the next five years, the Association of Indonesian Internet Service Providers (APJII) is now using the series routers Brocade MLXe-16 is able to support 100 Gigabit Ethernet (GbE) as the main component IIX. IIX two main router was installed at different locations to ensure high availability. With the substantial spare capacity in the 16-slot chassis, APJII has ample scope to install modules with a capacity of four-port 40 GbE and two-port module with a capacity of 100 GbE in the future.

APJII also plans to apply the technology Brocade Multi-Chassis Trunking (MCT). This technology will connect the two routers on top to create a single tool that is able to generalize the traffic load on network-network service provider that has a lot of connections to the center of the Indonesian Internet Exchange.

APJII currently has 278 members, including telecommunications companies, Internet service providers and content providers. Some 161 of which have been connected to the IIX via IPv4, while 51 of them also use IPv6 connection.
