Dock is part desktop OS X that characterizes Apple’s flagship computer operating system. Dock functions such as running apilkasi shortcuts or files and move from one application to another. To move from window to another window in an application, the user must use the OS X Exposé. But, what if asiknya application icon in the Dock to have features such as Windows 7, which the user can select a window which opens directly without having to rely on Exposé.
For those of you who want those features, can wear DockView apps in the App Store.
Like I mentioned earlier, DockView able to provide thumbnail windows of an application by placing the cursor over the application that has many windows.
DockView also supports thumbnail windows through the App Swithcer. Suitable for you who frequently use the App Swithcer to move the window. Still clumsy with App Swithcer? Just look at the previous tips, about maximizing the use of the App Swithcer.
Label the price is free, but it actually has a Dock View in app purchase to eliminate loading thumbnail window sometimes appears for a few seconds.
Additional Dock DockView a supplement that must be considered to accelerate access to switch between windows.
In this post we’ll look at five ways in roomates efficient coding we can use to help our garbage collector CPU spend less time allocating and freeing memory, and reduce GC overhead. Often Long GCs can lead to our code being stopped while memory is reclaimed (AKA “stop the world”). Duke_GCPost
The GC is built to handle large amounts of allocations of short-lived objects (think of something like rendering a web page, where most of the objects allocated Become obsolete once the page is served).
The GC does this using what’s called a “young generation” – a heap segment where new objects are allocated. Each object has an “age” (placed in the object’s header bits) defines how many roomates collections it has “survived” without being reclaimed. Once a certain age is reached, the object is copied into another section in the heap called a “survivor” or “old” generation.
The process, while efficient, still comes at a cost. Being Able to reduce the number of temporary allocations can really help us increase of throughput, especially in high-scale applications.
Below are five ways everyday we can write code that is more memory efficient, without having to spend a lot of time on it, or reducing code readability.
1. Avoid implicit Strings
Strings are an integral part of almost every structure of data we manage. Being much heavier than other primitive values, they have a much stronger impact on memory usage.
One of the most important things to note is that Strings are immutable. They can not be modified after allocation. Operators such as “+” for concatenation actually allocate a new String containing the contents of the strings being joined. What’s worse, is there’s an implicit StringBuilder object that is allocated to actually do the work of combining them.
For example –
a = a + b; / / a and b are Strings
The compiler generates code comparable behind the scenes:
StringBuilder temp = new StringBuilder (a).
a = temp.toString () / / a new string is allocated here.
/ / The previous “a” is now garbage.
But it gets worse.
Let’s look at this example –
String result = foo () + arg;
result + = boo ();
System.out.println (“result =” + result);
In this example we have 3 StringBuilders allocated in the background – one for each plus operation, and two additional Strings – one to hold the result of the second assignment and another to hold the string passed into the print method. That’s 5 additional objects in what would otherwise Appear to be a pretty trivial statement.
Think about what happens in real-world scenarios such as generating code a web page, working with XML or reading text from a file. Within a nested loop structures, you could be looking at Hundreds or Thousands of objects that are implicitly allocated. While the VM has Mechanisms to deal with this, it comes at a cost – one paid by your users.
The solution: One way of reducing this is being proactive with StringBuilder
Many consider me to be a 4K hater. The past few trade shows I’ve attended have been pushing it on consumers to replace their TVs, but I see less value in it. When it comes to a computer display, it is a different game. Unlike a 50” TV, we sit close to our monitors, even if they are 30” in size. We also have no worries about a lack of native content, since everything is rendered on the fly and native. There are no issues with the lack of HDMI 2.0, as DisplayPort 1.2 can drive a 3840×2160 screen at 60 Hz.
When it comes to 4K on the desktop, my main question is: how much difference will I see? ASUS is one of the first with a HiDPI display in the PQ321Q. While not truly 4K, it is a 3840×2160 LCD display that can accept an Ultra High Definition (UHD) signal over HDMI and DisplayPort. It also clocks in at a wallet-stretching $3,500 right now. The question is, are we seeing the future with displays here, or are we seeing a niche product?
What does 4K/UHD/HiDPI bring to the desktop? We’ve seen it for a few years now in smartphones and tablets, making their smaller screens more usable for reading and general work. My initial thought is more desktop space, as that is what it has meant before. With a 32” monitor and a pixel density this high, running it without any DPI scaling leads to a desktop where reading text is a huge pain. Instead I believe most users will opt for DPI scaling so elements are larger and easier to read. Now you have something similar to the Retina screen on the iPhone: No more desktop space compared to a 2560×1440 monitor, but one that is razor sharp and easier to look at.
To get to this pixel density, ASUS has relied upon a panel from Sharp that uses IGZO technology. IGZO (Indium gallium zinc oxide) is a material that replaces amorphous silicon for the active layer of an LCD screen. The main benefit is higher electron mobility that allows for faster reacting, smaller pixels. We have seen non-IGZO panels in smartphones with higher pixel densities, but we don’t have any other current desktop LCDs that offer a higher pixel density than this ASUS display. IGZO also allows for a wide viewing angle.
Jakarta – Founder and Chief Executive Officer of Google, Larry Page, said he likes to wear Google Glass although not as often as his fellow founders, Sergey Brin ie.
“It was like living in the future,” he said when presenting the company’s performance for the second quarter via teleconference. “It really makes me excited.” At a wedding in Croatia, Larry is seen wearing smart glasses.
“For some people, working on crazy projects are very challenging,” he continued. “Attempting to change the world with ten co-workers.”
Some projects that turned into a popular product used by many people in the world like Gmail, Chrome, and Android. “I see the results of our work on a number of projects and I feel satisfied.”
Several other projects are being worked on is the smart glasses Glass, Google Now, Project Loon, and a vehicle without a driver. “Misrepresentation if we assume the technology will be static,” he said.
Home computer network equipment manufacturers Linksys launches Wi-Fi modem router X3500 series in Jakarta, Wednesday (17/07/2013). This product is equipped with dual band capability, at a frequency of 2.4 GHz and 5GHz, which can be run simultaneously at speeds up to 450Mbps + 300Mbps.

CALIFORNIA – Microsoft preparing update hardware drivers Advanced Micro Devices (AMD) and Nvidia for Windows 8.1. Thus, users need not worry if will upgrade the latest version of the operating system.
Reported Hardware.info, Monday (01/07/2013), both companies are based in the United States announced the optimized drivers for Windows 8.1 Nvidia stressed that the company intends to have a reliable certified WHQL drivers available for one day.
AMD just published a list of new features, including revealing designated driver for the graphics processing unit (GPU) FirePro. While Nvidia, is reportedly not mention updated drivers for the graphics card with the Quadro series.
In addition to the graphic card’s drivers, original hardware vendor giant Santa Clara (Nvidia) also reveals updated device drivers for notebook GPUs. Nvidia also write a list of downloads or update Nvidia drivers are suitable for ‘Windows 8.1 Preview 62-bits’. Writing ’62-bits’ appears to be a typing error.
AMD calls several new features, including the option to play the video on the ‘refresh rate’ 48 Hz. In addition, the company is headquartered in Sunnyvale also brings hardware acceleration in video conferencing application Skype and Lync.
The information circulated previously revealed, Windows 8.1 will present a free phone features. Windows 8.1 Preview is reportedly updating Internet Explorer 11 (IE11), which will bring some interesting improvements.
Reportedly, IE11 will present the option ‘Click to Call’ which allows users to dial phone numbers directly from the browser. “Click to Call is a new feature in IE11. If you want to make phone calls by simply click the name mereka.Anda can choose to call Default Programs of IE11 or Skype, “said Microsoft.
Unggulkan Big Screen
The success of one of the Korean manufacturer to sell millions of smartphone unit have made a great sailing inspired many other manufacturers. However, to be sold at more competitive prices, various gadgets “rival” comes with fewer features. This is carried by Vandroid S5 from Advan.
u4-435-S5 AdvanAdvan Vandroid by PCplus quite on par with ZA987 OneScribe of Zyrex that appeared almost simultaneously. ˝ 5.3 capacitive screen with a resolution of 480 × 800 pixels here look quite a contrast and not inferior to similar products from leading brands. Advan S5 Vandroid called as “Smart Note” which is interpreted as a smart gadget with a variety of features that support mobile activities. This seems to be a campaign to educate consumers.
Smartphone MediaTek MT6575 is powered by a 1GHz processor (ARM v7) plus 512MB of main memory is actually not very special and still like most other large screen smartphones. Booting the system fairly quickly became hallmarks Vandroid Advan S5.
Here also 4GB of internal memory available. Unfortunately, only 2.2 GB of available capacity that can be used. It was only by the system / application alias can not be accessed directly by the user. As a result, users must add a microSD card (up to 32GB) as a storage media to store data.
The process of exploration in the menu Vandroid Advan S5 with Android 4 systems is quite smooth because of the PowerVR SGX531 GPU to handle graphics side. Advan smartphone also includes six important sensor that is not provided other competitors. With all those fittings plus dual SIM support, he can be had for less than Rp. 2 million. This makes it an attractive alternative products in the ranks of the many large screen smartphones on the market today.
Maybe not as perfect Advan S5 Vandroid similar smartphones from popular brands. When held casing feels slippery. However, to simply live day-to-day activities of this product is sufficient. At more competitive prices, even compared to other local brands, this smartphone is certainly attractive alternative option for on a budget.
Like the models in the fashion world, most outstanding ultrabook now prioritizes slimness of the body and a pretty view. However, these physical characteristics will result in a collision or vulnerable laptop face hostile weather conditions. That try to overcome this shortcoming by presenting a Lenovo T430 repeated his version into the ThinkPad series T430u.
Well, now ultrabook models (ThinkPad T430u) comes with the typical specifications of mobile devices are lightweight and power-saving. Examine the “u” as a marker ultrabook segment here. Series that we try (type 3351-7DA) contains an Intel Core i5-3317U 1.7 GHz, 4GB of main memory, and a 500GB hard disk. Also added a 4GB SSD for ultrabook-style get fast booting.
As general character ultrabook, the Lenovo ThinkPad T430u only include a little plug. This device only provides two USB 3.0 ports, LAN, HDMI, and DisplayPort. This device also has a wireless card slot that can be used to access the internet via a 3G connection. The slot itself is at the back of the laptop is sailing 14 ˝. The bottom of the laptop is also surprisingly easy to open with a special slot (no screwdriver) making it easier for you to upgrade components.
T430u also comes standard Thinkpad features such as finger print reader and an Anti-Theft technology from Intel. However, the laptop weighs 1.9 kg making it a lure is physical endurance-tested to military standards. This test requires the Lenovo ThinkPad T430u resistant to shock, dust, extreme temperatures, up to a humid environment. This is why this Ultrabook casing made slightly thicker (2.2 cm) with glass fiber plastic material to reinforce the cover.
To beautify the inside, Lenovo makes keyboad in design they call the Island-style that stood out. To give the impression of a minimalist, physical buttons for volume settings, wireless, and such removed. Instead, the available combination on the keyboard. Continue to be included on this keyboard also typical ThinkPad trackpoint. With lithiumpolymer 4220mAh battery, the laptop can be used for seven hours continuously.
Given its performance, the Lenovo ThinkPad T430u ultrabook par with most other equivalent. However, it seems to make a strong design-based Windows 8 Pro laptop is becoming prominent. This product is perfect for fans looking for a ThinkPad ultrabook or resilient.
