• Parallel and Concurrent Programming in Haskell

    Comments Off on Parallel and Concurrent Programming in Haskell

    As one of the developers of the Glasgow Haskell Compiler (GHC) for almost 15 years, I have seen Haskell grow from a niche research language into a rich and thriving ecosystem. I spent a lot of that time working on GHC’s support for parallelism and concurrency. One of the first things I did to GHC in 1997 was to rewrite its runtime system, and a key decision we made at that time was to build concurrency right into the core of the system rather than making it an optional extra or an add-on library. I like to think this decision was founded upon shrewd foresight, but in reality it had as much to do with the fact that we found a way to reduce the overhead of concurrency to near zero (previously it had been on the order of 2%; we’ve always been performance-obsessed). Nevertheless, having concurrency be non-optional meant that it was always a first-class part of the implementation, and I’m sure that this decision was instrumental in bringing about GHC’s solid and lightning-fast concurrency support.

    Haskell has a long tradition of being associated with parallelism. To name just a few of the projects, there was the pH variant of Haskell derived from the Id language, which was designed for parallelism, the GUM system for running parallel Haskell programs on multiple machines in a cluster, and the GRiP system: a complete computer architecture designed for running parallel functional programs. All of these happened well before the current multicore revolution, and the problem was that this was the time when Moore’s law was still giving us ever-faster computers. Parallelism was difficult to achieve, and didn’t seem worth the effort when ordinary computers were getting exponentially faster.

    Around 2004, we decided to build a parallel implementation of the GHC runtime system for running on shared memory multiprocessors, something that had not been done before. This was just before the multicore revolution. Multiprocessor machines were fairly common, but multicores were still around the corner. Again, I’d like to think the decision to tackle parallelism at this point was enlightened foresight, but it had more to do with the fact that building a shared-memory parallel implementation was an interesting research problem and sounded like fun. Haskell’s purity was essential—it meant that we could avoid some of the overheads of locking in the runtime system and garbage collector, which in turn meant that we could reduce the overhead of using parallelism to a low-single-digit percentage. Nevertheless, it took more research, a rewrite of the scheduler, and a new parallel garbage collector before the implementation was really usable and able to speed up a wide range of programs. The paper I presented at the International Conference on Functional Programming (ICFP) in 2009 marked the turning point from an interesting prototype into a usable tool.

    All of this research and implementation was great fun, but good-quality resources for teaching programmers how to use parallelism and concurrency in Haskell were conspicuously absent. Over the last couple of years, I was fortunate to have had the opportunity to teach two summer school courses on parallel and concurrent programming in Haskell: one at the Central European Functional Programming (CEFP) 2011 summer school in Budapest, and the other the CEA/EDF/INRIA 2012 Summer School at Cadarache in the south of

    Comments Off on Revealed, Microsoft SkyDrive Allow Skype and Tapped

    A document reveals how Microsoft is working with U.S. intelligence agencies to read messages from users, including helping the U.S. National Security Agency (NSA) secret unlock code Microsoft, Australia Guardian reported on Friday (07/12/2013).

    Confidential documents obtained by the Guardian of Edward Snowden, U.S. intelligence whistleblowers, said the level of cooperation between Silicon Valley and American intelligence agencies in the last three years.

    The document, among others, suggests, Microsoft helped the NSA to read the conversation at the new portal Outlook.com by giving the company secret code. NSA has access to Outlook.com including Hotmail before the messages are written in the form of a code (encrypted).

    Microsoft is working with the FBI this year that the NSA get easier access to the data warehouse via Prism SkyDrive which has 250 million users in the world.

    Microsoft is also working with the FBI to the intelligence agencies “understand” the issues that potential Outlook.com that allows users to use the e-mail alias for them.

    In July last year, nine months after Microsoft bought Skype, the NSA is proud to mention that the NSA has been able to increase the amount of video that they can access through Skype as much as three times through the Prism program. The materials obtained from Prism program routinely accessed by the FBI and CIA. One of the documents referred NSA has the name “team sport”.

    Snowden documents also reveal the tension between Silicon Valley and the Obama administration. Leading technology companies lobbying the government to be allowed to express the depth of their cooperation with the NSA to address customer concerns in terms of privacy.

    Corporate leaders are not trying to claim that they have collaborated and worked with intelligence agencies like NSA documents mentioned in the argument that the process is carried out according to the lawsuit.

    In a statement, Microsoft said, “If we increase the capacity (upgrade)-prudok and updating our products, we are not exempt from having to comply with applicable laws, both now and into the future.”

    Microsoft reiterated his argument that they provide the customer data “only in response to government requests, and we only serve the demand for specific address or identity”.

    Last June, the Guardian reported that the NSA claims to have “direct access” program through the Prism system leading internet companies including Microsoft, Skype, Apple, Google, Facebook, and Yahoo.

    Starting from his love for the graphic design world, John Djauhari now assembling machines printer (printer) 3D. By leveraging open source technology, 3D printers that can print documents assembled Johanes digital into three-dimensional objects.

    John worked as a product designer. Some clients who want to make a product sometimes is not satisfied if only to see the design in the form of digital documents. They want physical shape despite the small size.

    “Well, from there, why do not I make a 3D printer itself,” he said when met at the show Popcon KompasTekno Asia 2013 in Jakarta Convention Center, beginning last July.

    John also likes the toys (toys). Many colleagues who designed character toys and wanted to realize his ideas into tangible form. Some of them use the services of John for 3D printing.

    Keseriusan Johanes merakit printer 3D dimulai pada 2011. Ia mendirikan Bikin Bikin 3D Print dan aktif ikut pameran untuk memperkenalkan teknologi ini. Kala itu, desain luar printer buatannya masih berupa kerangka. Setelah melewati beberapa kali pengembangan, kini printer 3D-nya semakin akurat dan didesain menggunakan casing. “Akurasinya sampai 0,2 mm,” tutur Johanes.

    Akurasi itu dibuktikan dengan mencetak replika arca yang penuh detail dan lekukan. Johanes terlebih dahulu memindai seluruh bagian arca asli yang tersimpan di Museum Nasional. Setelah mendapat filepindainya, mulailah Johanes mendesain 3D lalu mencetak dengan printer buatannya sendiri.

    Memanfaatkan “open source

    Dalam mengembangkan printer 3D, Johanes memanfaatkan teknologi open source untuk driver dansoftware. Ia ikut dalam forum internet yang khusus membahas teknologi printer 3D.

    “Di forum ini, kita bisa tahu kalau ada algoritma yang lebih baik dan memberi struktur lebih mudah. Bukan cuma soal teknis, dari sana juga kita tahu soal materi yang mudah dicari dan lebih terjangkau,” jelasnya.

    Untuk mendesain bentuk 3D, Johanes menggunakan software Pronter Face dan Repetier. Komputer yang dipakainya terhubung ke motherboard printer melalui kabel USB. Motherboard inilah yang memerintahkan gerakan koordinat X, Y, dan Z, menerjemahkan dokumen digital menjadi obyek nyata 3D.

    Printer 3D yang dibuat Johanes masuk dalam tahap pengembangan akhir. Ia membuka pre-orderdengan harga Rp 10 juta. Setelah masa pre-order berakhir pada September 2013, printer 3D bakal dibanderol Rp 12 juta.

As we find a company for creating the next generation with medicine, we need to look at several other factors to be considered. The following are some of the factors to have a look at as we seek to get the best firm.

    Look at the availability of the science labs. The labs will aid in the process of research. Nothing will happen without research. The medicines will be as a result of looking at the way the cancer disease is physically getting to affect people. We look at how it can be effectively countered. The only way it will be effectively fought is by going into deep lab research.

    Check on the availability of resources for research. The people who are going to commit to research are to be paid. They need to be given some cash as an appreciation of the work they are doing. The government should set aside some money for this.

    Look at the cost of the services. Ensure that you seek the lowest people in the market who have set the lowest prices. Everyone will want to spend the least amount of money on the services he is being rendered. As a matter of fact, it is the desire of every individual to get the best of the market prices. The quality should be proportional to the prices charged. Always set a target of how much to be used. Choose to spend so low on several services. Different firms will charge a different amount of cash. So, choose o a firm that will mean to have the interests of the clients at hand.

    Look at the reputation of the firm. Let reputation be one of the key factors to look at. Ensure that you choose a reputable firm. Choose on a firm that many people like and they are free to hire any time of the day. Avoid getting firms which will affect the way you need your work to be done. Such firms may come with delays and lazing around in the job which is very wrong. Get the firm that has very many positive comments on the comment section. Avoid firms that are responded to very badly as they may delay your work by doing the worst work ever.

    Look at the experience of the firm. Choose a skilled firm that has been serving guys for some time now. The firm should have an understanding of all the activities it is carrying out. The firm should have relevant staff with the required credentials. Check on the certificates the expertise of the firm has. Ensure that they did a relevant course to perform the task.
