Sure, Fujitsu has a right to be proud of its K supercomputer — performing over 8 petaflops with just under 70,000 Venus CPUs is nothing to sneeze at. Intel isn’t giving up its status as the supercomputing CPU king, however, as it plans to bring exascale computing to the world by the end of this decade. Such a machine could do one million trillion calculations per second, and Intel plans to make it happen with its Many Integrated Core Architecture (MIC). The first CPUs designed with MIC, codenamed Knights Corner, are built on a 22nm process that utilizes the company’s 3D Tri-Gate transistors and packs over 50 cores per chip. These CPUs are designed for parallel processing applications, similar to the NVIDIA GPUs that will be used in a DARPA-funded supercomputer we learned about last year. Here we thought the war between these two was over — looks like a new one’s just getting started. PR’s after the break.
Intel adds to ULV processor line with 1.8GHz Core i7 and i5 options, one of them to star in ASUS UX21
Intel’s so-called Ultrabooks may be a little way off into the distance at the moment, but the company isn’t making you wait until its Ivy Bridge rollout to get a taste for ultraslim laptops with some real power inside them. A trio of new ultra-low voltage CPUs, each rated with a TDP of just 17W, has been added to the company’s catalog, starting with the top-tier Core i7-2677M, whose pair of cores run at 1.8GHz by default but can be sped up to 2.9GHz when duty calls. Then there’s the i7-2637M, which looks to only differ in clock speeds (1.7GHz default, 2.8GHz under Turbo Boost), and the i5-2557M that makes do with a 3MB L3 cache (1MB less than its i7 brethren) and a 1.7GHz / 2.7GHz speed range. All three 64-bit, 32nm processors also integrate a GPU (350MHz base clock, maxes out at 1.2GHz) within their walls, which is what makes their ascetic power consumption all the more impressive. OEMs should soon start splicing these new options into their next generation laptops, and while the obvious speculation centers around a MacBook Air refresh, CNET tells us the Core i5-2557M has already found a home in ASUS’ upcoming UX21, a (purportedly) sub-$1,000 11.6-inch featherweight contender.
Sebuah perombakan besar dalam nama domain di internet telah ditorehkan oleh ICANN dengan telah disetujuinya pendaftaran TLD (top level domain) baru yang bisa dipakai dan dikuasai oleh perusahaan atau wilayah tertentu. Aturan ini memungkinkan sebuah pihak memiliki alamat internet pribadi mulai tahun 2012 nanti, misalnya Google dengan alamat berakhiran TLD .google, Ebay dengan .ebay, dan seterusnya.
Saat ini alamat domain internet utama biasanya diakhiri dengan TLD standar seperti .com, .net, hingga domain negara seperti .id. Dengan aturan baru ini nantinya bisa muncul TLD baru yang semakin beragam, termasuk juga domain dalam bahasa non latin seperti bahasa Arab maupun China.
Untuk memiliki alamat domain ini para pendaftar harus membayar sekitar $185,000 dan harus mengisi aplikasi pendaftaran untuk verifikasi sepanjang 360 halaman. Prosedur ini dimaksdukan agar domain baru ini tidak disalahgunakan dan hanya ditujukan untuk mereka yang memiliki merk dagang sesuai alamat yang dimiliki nantinya.
Beberapa waktu lalu, Microsoft mendepak tools pembobol Windows Phone 7 (WP7) dari Marketplace. Kini, tiba-tiba mereka justru merestui perangkat tersebut.
Tools pembobol tersebut bernama ChevronWP7. Aplikasi ini diklaim menjadi tools pertama yang dibuat para pengoprek untuk membedah Windows Phone 7. Aplikasi ini diciptakan oleh tiga sekawan: Rafael Rivera, Long Zheng dan Chris Walsh.
Para pembuat Chevron WP7 mengaku membuat aplikasi ini untuk memberikan akses kepada pengguna atau developer agar bisa menyusupkan aplikasi pihak ketiga tanpa harus dipersulit dengan persyaratan di market place Windows Phone 7.
Kini tim pengembang ChevronWP7 justru mendapat restu penuh dari Microsoft. Mulai sekarang para pengembang aplikasi bisa bebas menggunakan ChevronWP7 untuk memodifikasi Windows Phone, namun dikenakan biaya. Asal hal itu untuk tujuan pengembangan aplikasi.
“Sejalan dengan dirilisnya Windows Phone Dev Podcast, kami akan merilis juga layanan Windows Phone unlocking, sebagai bagian dari ChevronWP7 Labs. Ini segera tersedia bagi para pengembang di semua negara,” tulis pesan Microsoft.
Tampaknya, Microsoft justru memanfaatkan celah tersebut sebagai bagian dari bisnis mereka. Developer pengguna ChevronWP7 bakal dikenai sedikit biaya via PayPal saat ingin menggunakan aplikasi tersebut.
Regular expressions are an essential part of any programmer’s toolkit. These are very useful kits for web developer to validate, match or replace text. To help user there are number of tools and resources are developed. The tools and resources like Greedliness / Laziness, Back referencing, Word boundaries, Named Groups, Word Boundaries, Atomic Groups, Recursion, Call Backs, Commenting, Regex helps to test regular expression in a different ways. If you would like to modify a htaccess file to make clean URLs, or some other advanced works as filtering RSS or other data. Some resources and tools given bellow which let you step forward to achieve good mastery over regex.
With the enormous technology development, everything is being made simple, accessible, and user-friendly. Regular expression also known as ‘regexp’ or ‘regex’ is one such method that offers a brief and adaptable mode of text strings to describe a search pattern with minimal effort. The idea of regular expression is to provide great flexibility in matching the text patterns or strings and hence provide a powerful approach for an easy search.
Why regular expressions
The answer is very simple. It is one of most powerful tools a programmer can think of! However just take a look at some of the reasons :
- Regular expressions are merged to many programming languages and tools such as the vi editor of Unix/Linux OS (operating system); the grep command of the OS; Perl and PHP programming languages.
- Every usage of regular expressions evokes a powerful search engine and this searches for the text with the specified patterns.
- You are offered with dual match strings – eg: Find all lines having either Mangoes or Grapes – Mangoes|Grapes.
- Regular expressions are language study by themselves – in other words – a language within a language.
- You may match a whole category of characters – eg: Match all lowercase letters for 1 character position: (a-z) or (0-9) or (ABCXYZ456).
- You may match any character by the usage of a period – eg: Match any 3 characters: … (3 periods), or match characters at the beginning or end of a line.
- With regular expressions you can almost match anything as it can scan any file or date that are in an identifiable pattern.
- And much more…
Basic and Extended Regular Expression
There are the two main types of regular expressions. These provide you with all the required matches according to your need. Either you want to match a single character, or a range of characters in the desired pattern. You are exposed to Perl-derivative regular expressions, Simple regular expressions, Posix character classes, and Posix basic regular expressions with the apt examples for you to learn to use the regular expressions appropriately. Expressive power and compactness
