New Sony Vaio VPCEB1J1EWI Laptop Computer

September 15, 2018

As regarding the general theme, the Sony Vaio VPCEB1J1E/WI laptop computer is not a fashion icon, but it is yet another solid, really well placed together notebook computer coming from Sony. Whilst suppliers have a tendency to over complicate their own designs in an effort to stand out, Sony achieves to create a sense of type in a far a lot more restrained way. Every thing is in the appropriate area and posesses function, leaving ones own option of coloration to make the affirmation – in the event that’s what you want.

Connectivity seriously isn’t too poor, either. Though the VPCEB1J1E/WI laptop computer doesn’t have eSATA or USB ‘sleep and charge’ features, it does own mini-FireWire – a significantly rare terminal on laptop computers lately. Everything else is very normal, such as: three USB ports (2x left, 1x right); High-definition multimedia interface along with VGA for video; a 34mm ExpressCard port, audio jacks (1x earphone, 1x mic); an Ethernet port around the backside along with independent memory card slots intended for Sony’s little-known forms plus the extra normally applied SD card format.

Plenty of manufacturers deliver their own laptop computers in the selection of styles, but Sony happens to be on it for for a longer time as compared to most. A person can certainly trace that all the way back towards C Series around February 2007, that was replaced by the CR Line in August that time and then the CS Series recently. Regrettably, though the outgoing CR was preferably handy, the CS was really a substantial step backward, thus we weren’t surprised to notice it straight away replaced by the Sony Vaio VPCEB1J1E/WI using the advent of Windows 7.

You will find 5 colourings accessible: white, red, pink, blue and black. Any pink version regardless of own liking, is most likely the least likable choice of them all. Even those that love pink will probably see the brighter, a lot more lively shade viewed around the lid and hand rest fails to sit well with the instead sickly, light shade utilized within the rest in the laptop. No true problems might be made of the other picks, nevertheless, and all of us in particular enjoy the red/black and white designs.

As for our product, it is powered by an Intel Core 2 Duo P7450 running at 2.13GHz that’s supported by a plentiful 4GB DDR3 Ram memory. Sony has also possessed the experience to install a 64-bit variation of Windows 7, so all that system memory is becoming set to very good use. A 512MB nVidia GT 230M graphics cards serves up the visual treats, while regarding to hard drive you obtain a 320GB disk drive. Gigabit Ethernet, Wireless-N Wi-Fi along with Bluetooth are all existing as well, creating a thorough spec.

In common with all of Sony computers recently, the VPCEB1J1E/WI shows an isolation-style keyboard – an advancement Sony itself started. Without doubt this could be the identical keyboard as located within the VAIO NW Series earlier within the same year, which is beneficial news since it have an brilliant keyboard. Sony has seriously nailed the key measures on these kinds of keyboards, getting rid of the shallow feel of earlier efforts when keeping the snappy response. Allied to a faultless design, the Sony Vaio VPCEB1J1E/WI laptop computer features among the ideal keyboards of any kind of consumer laptop.

The True And False Identification Of Iphone 4s Accessories

September 6, 2018

iPhone 4S did not take the disposable packing or one-off seal, So it is easy to take iPhone 4 s pack apart and again encapsulate it. And so it creates an opportunity for iPhone 4s sales profiteers to switch the original earphone, data cable, and chargers.

The price difference between original accessories and assembly parts is very big. In the driving of the benefit, the possibility of switching is bigger. So please check original accessories carefully when choosing iPhone 4s. If the iPhone original accessories are switched by profiteering, your loss is not small. In addition, please check the packing box. SIM card stand and machine’s three codes are also very important.

iPhone 4 s carry the following accessories: Earphone with microphone and remote control, USB cable, USB power adapter, and SIM card out tool.
The quality of original iPhone 4S accessories is very well; the material of cable is soft. Printing’s handwriting is clear. In a word, working is very well. In addition, original accessories have to follow anti-fake mark.

Earphone
The words on the outer package and the words on the headset are strictly corresponding in the case of not moving iPhone 4s original earphone. In addition, we can find the local country works on the cable of the original earphone.

SIM card tool(Taking card device)
The iPhone taking card device is small, but there are still some differences between true and false ones. We often can see a concave point on the false taking card device, and really taking card device didn’t have. In addition, there are local country words on the side of really taking card device, if we watch carefully.

Card stand details
There is serial number on the border of the iPhone 4s card stand. This number is the same as the number of internal iPhone and packing box, this is three code unity everybody often says.

Note: If there is no serial number on the card stand, or serial number is different from the number of iPhone packaging or internal iPhone. It shows that the iPhone has been opened.

The charger and data cable

Two accessories do not have obvious anti-counterfeiting logo. There is no big difference from the shape. We can only judge them from the wire quality and print accuracy.

In addition, non-original iPhone accessories also have a division of good and bad. If the original accessories are broken, I suggest you choose trusted iPhone accessories wholesale store.

Audio Technica At2020 Or Blue Yeti – The Best All-round Usb Microphone

August 10, 2018

The question I am most often asked is whether to buy the Blue Yeti USB microphone or the AT2020 from Audio Technica.

The Yeti and the AT2020 occupy the sweet-spot in terms of price, quality, functionality and quality so deciding which is the best USB mic comes down to you personal preference and how you intend to use the mic. Both are mid-priced mics, and both mics plug into your USB port and offer professional quality recording.

The Blue Yeti USB mic is the top-of-the-range offering from Blue microphones. It’s a large, quite heavy mic which is perfect for desktop or studio use. It’s solid and sturdy however it reduces the portability therefore if you have to have a lightweight unit to cart around, the Yeti perhaps isn’t your best option.

The AT2020 from Audio Technica is a more compact unit that is a bit more expensive but it is a bit more versatile for road-warriors. It’s also far easier to find a shock-mount to fit the AT2020 which greatly reduces background noise.

Portability
The yeti is industrial and robust whilst the AT2020 is sleek and light-weight. Should you want portability, the AT2020 wins every time

Sound quality
The Yeti and the AT2020 both have classy sound quality and adds a deep richness to just about any voice and they also both pick up the warm tones of an acoustic guitar perfectly. It is difficult to split the difference in quality of sound but the Yeti has 4 different recording modes based on the sound source so just pips the AT2020.

Ease of Setup
After I purchased my blue Yeti, I was recording in a minute of opening the box. I simply plugged in the mini USB and connected it up to my iMac. System preferences appeared and I selected the Yeti for input and output. Boom – ready and recording in 30 seconds!

The AT2020 is also simple to get started but I’ve never set one up personally so it would be unfair of me to comment. We’ll have to say it’s a draw.

Latency
There is a noticeable lag with the sound of the AT2020, as the sound gets processed by the sound card before it’s fed back to the monitor headphones. This echo can be quite distracting. You will find some premium software available to help rectify this but with the Yeti, there just isn’t a problem. There is a headphone monitor port directly in the microphone so the monitor is one hundred percent real-time. It’s warmingly haunting to hear your own voice in your headphones sounding so full and rich.

Features
On paper the specs of the Yeti are far superior. It’s the only officially THX certified USB mic on the market and has 4 recording settings to pick up sounds from various directions as needed. In the omnidirectional setting, it’s great for recording a live session with a few musicians in the room playing at the same time. The At2020 isn’t as versatile with only the cardioid setting available but it’s no wallflower either. The Yeti gets another point on this one.

Accessories
Both microphones come with a stand with a small base, so they both work well if you’re working at your desktop, recording a voiceover or podcast. But if you’re recording screencasts or typing during the recording, both micas will pick up vibrations from the desk.

That’s where the AT2020 comes into its own simply because it’s a lot easier to locate a shock mount which fits. The yeti is simply too big for any widely available shock mount.

The best way to take your recordings to the highest level is to use a freestanding microphone boom. They both have standard mounts allowing you to use any microphone stand, and if you would like the adjustability of an “anglepoise” swivel style mount such as the rode PSA1, then both will work fine. Keep in mind you will need a high tension mount to counterbalance the weighty Yeti.

Just like most microphones, the Yeti and the AT2020 would be improved by adding a pop-filter to take out those popping “p”s. Blue microphones have their own pop filter but I’d recommend a plain pop filter that will save you 10 or 20 bucks.

The AT2020 comes first on accessories just because it’s easier to purchase a shock-mount to fit. But it is a close call and definitely depends upon what you require.

The Final Verdict
We have got a tie with 3 1/2 points each to the Yeti and AT2020.

And so it really depends upon what you want.

If the lack of portability isn’t an issue for you and you don’t need a shock mount, in my opinion the yeti is the foremost USB microphone available.

If portability is essential than audio flexibility, then i suggest the Audio Technica AT2020.

Software encryption status quo and development trend of the industry

July 23, 2018

Software developers usually use some kind of encryption technology to protect their software to prevent illegal use. Also need software encryption software is authorized to purchase content, in order to maximize the sales profit.

Software encryption technology is divided according to whether the use of a dedicated hardware-based encryption hardware and software-based encryption. Hardware-based encryption, encryption need to bind with a dedicated hardware device, the hardware encryption encryption locks, commonly known as a dongle. Software-based encryption, encryption does not require dedicated hardware, general binding digital license with the the terminal device hardware and software information, also known as the electronic authorization forms.

Simply think drive-based hardware encryption security than software-based encryption is not correct, because the more involved in software security, including encryption products, security, encryption policy design, application software, operating systems, , hardware, data communications, and so on, is a comprehensive technical areas, not simply by a to determine whether security.

In other countries, the market share of the electronic authorization and encryption locks are evenly matched. Habits and historical reasons, the encryption locks also occupy a certain market share. Encryption locks, however, is the network developed product of the times, is a pure client technology, lack of management and statistical functions, the presence of hardware production, logistics, driver installation inconvenience, not only the high cost, and can not be achieved network distribution and sales of the software, is gradually decline.

The development of the electronic authorization that is in the ascendant. Electronic license protection methods have become more and more integrated into the Internet technology, cloud computing and SaaS concept is not only more convenient to use and manage software electronic issue and be able to achieve, but also in line with today’s green low-carbon development concept, has replaced the encryption locks Exclusive the software encryption market trends. The more well-known companies in the world, Microsoft, IBM, Autodesk, SIEMENS, Adobe and other software are electronic authorization protection mode.

In the country, the use of encryption software developers lock higher rates, with foreign habits and historical reasons for the continuation of the following two reasons:

1 domestic manufacturers generally considered security encryption locks electronic authorization.

There are not any available electronic license products too high, the price of foreign electronic authorization.

In fact, with the growing improvement of the network environment, the network activation for most domestic users is not a problem. And also mentioned earlier, that the point of view of the security of encryption locks electronic authorization sided incorrect. From a realistic point of view, the encryption locks through hardware replication easier to crack, but completed piracy industry chain has been formed. Instead, electronic authorization because the hardware can not be copied, but also need to network activation and validation, in fact, have very good protection effect. In addition, the domestic has also appeared in some licensed products provide electronic 2-3 company must grow with the development of China’s software industry and grow up.

Therefore, the encryption software industry trends hardware, networking, and information technology. Below, we talk about, from the software encryption method specific to elaborate software encryption status quo and development trend of the industry.

First, the software encryption method

As mentioned earlier, the software encryption technology is divided into encryption hardware-based and software-based encryption.

A hardware-based encryption

Hardware-based encryption encryption locks, some important information, such as encryption keys to sensitive data, authorization documents, custom algorithms, etc. can be stored in the dongle.

The encryption lock interface form is divided into two kinds of parallel port and USB port. The parallel port is the early use of the form, because the mating inconvenient and conflict with the printer, and now has less use. Most developers use are USB interface dongle.

Encryption locks from the two types of CPU type, a microcontroller for CPU and another using a smart card chip as the CPU the microcontroller hardware itself easily crack or copy, so more and more high-end encryption locks using a smart card chip CPU, to prevent hardware crack. But more and more smart card dongle crack, first, because the chip is more and more advanced analytical techniques and instruments; smart card program to be written to the chip factory to manufacture in this session program may leak; encryption locks of the same brand the CPU procedure is the same, only different developers data and key, if these files are spread out, it is easy to copy.

Dongle has a certain degree of security strength, but there are also a number of drawbacks:

1) apply to the traditional one-time perpetual license, can not facilitate the achievement of the trial version and on-demand purchase

2) the presence of hardware production, logistics, installation and maintenance costs

3) can not be achieved the issue of Internet-based electronic upgrades, tracking and management

4) Once cracked, can be copied in large quantities, it is difficult to remedy

Two software-based encryption

Software-based encryption, electronic authorization, and specific also divided into two kinds of registration number and license file:

Registration code is also known as the serial number or authorization code, obtained by a transformation of the the software user computer hardware and software information, the available hardware and software information, including: CPU serial number, BIOS serial number, card number, hard drive serial number, computer name, etc. . Transform algorithm used a custom algorithm or standard encryption algorithm. User or first use of the software installation process, you need to enter the registration code to verify. After authentication, the software can be used normally. The approach has the advantage of the registration code protection is simple to use, the drawback is that security is not high, unable to achieve complex authorization requirements.

License file and the registration code to bind the same computer hardware and software information, just a registration code length restricts use of both hardware and software information, the license file can use multiple hardware and software information. Moreover, the license file can contain more information, so you can achieve the complex authorization requirements, and can even store some user information. The typical license file method is to use the private key of the asymmetric algorithm to sign the license file, while the public key is embedded in the software code. Asymmetric encryption and decryption process, the private key authorization server exists, it is difficult to crack through the analysis of authorization documents.

The advantages of the electronic authorization protection does not require additional hardware, and therefore does not need to install the driver and client components, electronic software issue. The drawback of the electronic license protection mode is not networked users need to manually extract the computer information, and then manually import registration codes or license, is not very convenient to use. In addition, the domestic electronic authorization few of the developers of the product, which also limits the popularization and promotion of electronic license protection technology.

Second, the software encryption industry development status

1. Encryption locks

The major foreign dongle provider SafeNet, Inc. in the United States and Germany Wibu.

Encryption locks provider deep Si Luoke and Feitian. The two companies because of the low prices, the first to introduce the smart card encryption locks localized well to occupy a certain market in the country.

2. Electronic authorization

Foreign company licensed products to provide electronic Flexera Software and SafeNet which, Flexera Software is focused on the field of electronic authorization, the product’s ease of use and functionality are doing better, but the price of the product is also very high.

The domestic electronic authorization products company the Beijing Biteansuo (BitAnswer), Shenzhen-use the (Euse) Safengine Company.

There are very few companies will develop their own electronic authorization scheme, but the developers to develop their own programs usually exist the following questions:

1) the development of non-professionals, there are many loopholes in the security

2) is difficult to achieve flexible licensing control, management and statistical functions very simple or no

3) are likely to be introduced in order to solve the immediate problem of short-term program, and produce far more than expected in the future due to the security, stability and scalability issues continued to invest

4) can not meet market changes brought about by the new demands on software licensing model

Software encryption industry trends

The software encryption industry trends is closely related with the development trend of the software industry. With the popularity of cloud computing and SaaS, provider of software products is change in the direction of the network and platform. Used for the majority of software developers, SaaS products can not only save a lot of hardware and software purchase and maintenance costs, you can also purchase demand, while reducing the use of risk, forcing platform providers to continuously improve products and enhance services to retain customers.

Toward the development of network and platform development is also a software encryption technology trends. The view on the current development trend, the encryption lock technology has developed very mature market is nearing saturation, slow growth. The existence and use of the hardware habit makes encryption locks can not keep up with the pace of development of the Internet era, will be replaced by the electronic license.

Electronic authorization license from early registration code form to the feature-rich documents in the form of changes in technology is undergoing authentication method from offline manually verify the development of automatic network authentication. Authorized management thinking of in particular, the electronic license technology from a single software license certification development as an authorized certification, authorization management and statistical information, and other function of both, greatly increased the authorized level of information for software developers.

Can predict the future of electronics licensed products should have the following main characteristics:
