AMD vs Intel Processors


AMD vs Intel processors is a major dilemma these days while buying a computer or a laptop. Here is a low down on how these two fiercely compete with each other.

The central processing unit (CPU) is to computers what brain is to human beings. If the CPU does not function properly, a 22 inch LCD monitor would be absolutely futile. The point, therefore is that there is no use of 'beauty without brains'! Jokes apart, though, in computers, the processor is what you pay for the most, and then the other things follow suit. Talking of processors, Intel and AMD processors are the ones selling like hot cakes in the market. Which one is better, depends on what kind of a computer setup you are looking for. For now, lets take a look at AMD vs Intel Processors.

AMD vs Intel Processors Comparison

The Intel Story
Intel is undoubtedly the best processor on the face of this earth, I guess. You just cannot imagine a computer without an Intel processor! Although there were a few hiccups in between with the Pentium 4, the core series has got them back right on track. The latest chipset by Intel, the 'Xeon' is a dual core processor which boosts computer performance for business applications. If you purchase a P4 3.4 GHZ with HT Technology or a Xeon Processor you will spend between $4 and $1200 on an average. Intel, synonymous with processors, almost has a faster processor, which can handle much more. These processors have always been top notch, when it comes to main clock speed. Moreover, the need for a front side bus has been totally bypassed by Intel chips.

AMD Saga
Advanced Micro Devices' AMD Turion and Athlon are giving a tough fight to Intel. Starting off by making chips almost exactly like Intel's, later AMD started developing their own microprocessor chips. AMD processors have good power, if you are looking at gaming and stuff, but nothing more. However, AMD wins hands down when it comes to price in the battle of AMD vs Intel processors. Moreover, AMD has worked a lot on the power consumption and heating factor of its processors and AMD's Phenom is doing pretty well in the market.

AMD vs Intel Processors for Gaming
The cardinal question, when it comes to AMD vs Intel processors, is which one is good for gaming. Well, many a times, the gamers have given a nod to AMD processors. First things first, AMD is good when it comes to power, but that's that, for gaming. Yes, you save money and you can use the same to upgrade your system with a new graphics card and stuff. However, if you are not the kind who would be hooked on to games for ever, Intel is the way to go (It almost always is, isn't it?). If you are not a voracious gamer, Intel is the way to go. Even AMD's fastest chip, the Phenom X4 9950 (about $240), comes second when compared to equivalent systems packing a Core 2 Duo E8500 in dual-core friendly games. Eventually, it is up to you to decide who is the winner in AMD vs Intel processors based on what you want to do.

AMD vs Intel Processors Laptops
When you are looking at comparing the 2 processors for laptops, core clock speed is the first thing to consider. Intel is way ahead of AMD in that respect. When it comes to front side bus, which enhances the communication between multiple processing cores, Intel and AMD both are at par, nearly. Moving onto the features of lets say AMD Turion, it has several features in its dual core technology. To name a few, these are cool core and power now which work on the issues of increased power consumption and reduced generation of heat. Intel's Core 2 Duo and other high end processors are much more efficient and are faster, which works for laptop computers. This is one of the aspects when it comes to what to look for when buying a laptop.

Last but not the least, in the AMD vs Intel processors dilemma, is the heat generation factor and cost. It is better to fully inquire about how do both the processors deal with the problem, though both of them have improved greatly in this department. When it comes to price, AMD may have an advantage over Intel, as they are cheaper. Again it depends what is going to be the end usage, which one will be a preferred choice, with regards to AMD versus Intel chips comparison.

Some of the AMD vs Intel processors reviews may be a bit biased towards Intel, but that is crystal clear considering that Intel, by far, seems to be the best when it comes to processors, even if they are a bit expensive. You win some you lose some, right? Eventually it is not possible to write off either one in any department, unless you know what you want and what you are looking for, when it comes to AMD vs Intel processors. This is where I sign off!

SEO Engine

best SEO tricks » permalink, improve blog traffic, By default, Blogger gives you this dynamic URL for your post: “http://yourdomain.com/?p=SOME-ID-NUMBER”. The best SEO permalink structure is to have your post appears with ‘category’ and the ‘post title’ in the URL.
This looks something like this: “http://yourdomain.com/category/post-title”
Why is this the best SEO permalink structure compares to the other structures?
To simply put, this permalink structure allows you to have ‘more’ keyword loaded into the URL of your post. Since the category that you’ve placed your post under usually related to the post title (which hopefully is keyword-loaded itself), you will have the extra SEO benefit if other people use that permalink structure to link your post.
How to Change the Default Permalinks to ‘Category/Post-Title’ Permalinks
In order to change the default permalink structure, you need to go to “OPTIONS -> Permalinks” in your admin panel and paste this code into the BOX after “Custom Structure:”
/%category%/%postname%/
Next, click the “Update Permalink Structure >>” button; if blogger does NOT automatically update the permalink structure to for you–don’t worry–just do the following:
-If you don’t have a .htaccess file in your root directory (public_html/.htaccess) already, just ‘create a new file’ and name it .htaccess and place it in “public_html” directory or whatever directory you have your blogger blog installed (e.g. public_html/blog/.htaccess, which is equivalent to yourdomain.com/blog/.htaccess).
-Then, copy and paste the code blogger gives you after clicking on the “Update Permalink Structure >>” button into your .htaccess file. *Note: You need to click on the some option (e.g. ‘Edit’) of your .htaccess file to open up a window to paste your permalink code in the file.


Tuntunan Puasa Ramadhan Untuk Anak-anak


PUASA ANAK-ANAK

mengenai puasa Ramadhan untuk anak-anak, walaupun Ia tidak wajib puasa tetapi sepatutnyalah walinya menyuruhnya mengerjakannya, agar ia dapat membiasakannya dari kecil, yakni selama anak itu dapat dan kuasa.

diterima dari Rubaiyi' binti muawwidz bahwa rasulullah saw pada hari 'Asyura mengirim utusan ke desa-desa kaun Anshar guna menyampaikan:

"siapa yang telah berpuasa dari pagi hari hendaklah ia meneruskan puasanya, dan siapa yang dari pagi telah berbuka, hendaklah ia mempuasakan hari yang tinggal!"

maka setelah itu kamipun berpuasalah, dan kami suruh anak-anak kami yang masih kecil berpuasa, kami bawa mereka ke masjid, kami buatkan mereka semacam alat permainan dari bulu domba. Maka jika ada diantara mereka yang menangis minta makan, kami berilah ia alat permainan itu. Demikianlah berlangsung sampai dekat waktu berbuka"(riwayat Bukhari dan Muslim)

Hukum Puasa Ramadhan Dalam Fikih sunnah

HUKUMNYA
puasa Ramadhan itu hukumnya wajib, berdasarkan kitab, sunnah dan Ijma' . mengenai kitab, firman Allah Ta'ala:
"Hai orang-orang beriman, diwajibkan atasmu berpuasa sebagaimana telah diwajibkan atas orang-orang sebelum kamu, semoga kamu bertaqwa." Al-Baqarah: 183
dan firman-Nya pula:
"yakni pada bulan Ramadhan, yaitu saat diturunkannya Al-Qur'an yang menjadi petunjuk bagi manusia dan penjelasan dari pedoman serta pemisah - antara yang hak dan yang batal, maka barang siapa yang berada ditempat pada bulan itu, hendaklah Ia berpuasa." Al-baqarah: 185

mengenai sunnah, maka sabda Nabi SAW:
"didirikan Islam atas lima dasar, yaitu: mengaku bahwa tidak ada Tuhan melainkan Allah dan bahwa Muhammad utusan Allah, mendirikan shalat, membayar zakat, berpuasa pada bulan Ramadhan dan naik haji"
dan pada hadits Thalhah bin 'Ubaidillah tersebut bahwa seorang laki-laki bertanya kepada Nabi saw.:
"ya Rasulullah, katakanlah kepadaku puasa yang diwajibkan Allah atas diriku!, Ujar Nabi Saw: "puasa Ramadhan" tanya laki-laki itu pula; "apakah ada lagi yang wajib atasku?" Ujar Nabi;"tidak kecuali kalau anda berpuasa sunat."

dan umat Islam telah Ijma' atau sekata atas wajibnya puasa Ramadhan, dan bahwa ia merupakan salah satu diantara rukun Islam. Hal itu dapat diketahui dari ajaran agama secara naluri dengan tak usah dipikirkan lagi, hingga orang yang mengingkarinya berarti kafir dan murtad dari Islam.

And The World Is Silent: burma massacre

and the world is silent about burma massacre

Muslims Massacre In Burma and Silence of Media on this issue

Burma has a population 75 million with the Muslim population being just 0.7 million. The Burmese Muslims have been under this affliction after 1962 when the Army usurped the power in Burma. It all started on 3rd June 2012 when 11 innocent Muslims were killed by the Burmese Army and the Buddhist mobs after bringing them down from a bus. A vehement protest was carried out in the Muslim majority province of Arakan, but the Protestants fell victims to the tyranny of the mobs and the army.

Trying to elude capture and an imminent killing; Burmese Muslims thronged to the Bangladeshi border, but all they met was dismay. The Government of Bangladesh refused to offer them asylum.

Over 500 Muslim villages have been incinerated hither-to. Thousands have been exterminated. The persecution of the Burmese Muslims at the hands of the Buddhist mobs is at its full swing. Yet all the human rights organizations have maintained a criminal silence up till now. Has the Muslim world become so callous that they remain undeterred by such genocide?

This is not a new thing or an unprecedented massacre. Muslims have been a subject to such hostility even before. If we go through the
annals of history we come to the very tenable conclusion that Muslims were always on the suffering side. Islam is a religion of peace and
harmony. It doesn’t allow its followers to lay-waste any other tenet. This leaves behind a big question mark. Why are the followers
of such a peaceful religion being oppressed from time to time?

The fear stricken faces of the poor Burmese Muslims really cuts one apart. The glimpse of their bruised bodies is a heart rending
spectacle. Where is the UN now? Why isn’t the International media highlighting this issue? Why are the competitive authorities of the
Muslim world procrastinating?

Stop killing the Burmese Muslims. JI did a meritorious job by staging rallies against this brutality. The government of Pakistan should
raise a voice in favor of the poor Burmese Muslims at the international forum. The whole Muslim world should join hands to get
the poor Burmese out of their distress and misery.

In lieu of launching into a tirade against the killings, something should be done on the ground. If we don’t help out our brothers there then we are equally responsible for their bloodshed. We won’t be able to satisfy our conscience, and the abrasive cries of the Burmese Muslims will keep on pinching us throughout our lives
